impact of foundation pit construction at Subway #1 and shield tunneling at Subway #3, i.e. superpose in linear way the above-described conclusions for impact of foundation pits at Subway #2 and shield tunneling at Subway #3 respectively, that after reinforcement Erqi Tower's maximal settlement is 19.2 mm within the limit of 20 mm and its foundation tilt is 0.0005, within the limit of 0.001. ......................................................................... 405  6.2.2 Analysis of Cumulative Impact during the Operation Period .................................... 405  6.2.2.1 Analysis of Cumulative Impact on Traffic during the Operation Period................................. 405  After the subway is put into operation, massive passengers will be attracted to travel by subways thanks to its quickness and convenience. Safety-related hidden hazards may be present at subway stations, especially at the transfer stations and those located at the down-town areas because the heavy passenger flow that concentrates around stations at the peak hours will cause temporary congestion or jam at some local stations and is hard to evacuate quickly in case of emergency............................... 405  The subway, upon operation, will be connected seamlessly with the high-speed railway station, the train station and the long-distance bus station to form an integrated traffic network by connecting it with different public transport systems at proper positions including the public transport stops, BRT and the parking lots in order to divert passenger flow and save time and cost for passengers. ........ 405  6.2.2.2 Analysis of Cumulative Impact of Noise during the Operation Period ................................... 405  6.2.2.3 Analysis of Cumulative Impact of Vibration during the Operation Period ............................. 406  6.2.2.4 Analysis of Cumulative Impact by Air Pollution during the Operation Period....................... 408  6.3 Mitigation Measures of Cumulative Impacts of this Project................................................. 409  6.3.1 Mitigation Measures of Cumulative Impacts during the Construction Period ........... 409  6.3.1.1 Mitigation Measures for Cumulative Impact by Continuous Construction near the Memory Tower for “Feb. 7th” ........................................................................................................................... 409  6.3.2 Mitigation Measures of Cumulative Impact during the Operation Period ................. 410  6.3.2.1 Measure to mitigate the accumulative impact on traffic ...................................................... 410  11    1. Based on the demand from traffic development, considering the land development mode along the subway route, the characteristics of connecting passenger flow, land condition, road network condition and the traffic condition, specific studies have been done on some topics concerning the integrated traffic plan in order to build a well-developed integration traffic network to meet the demand of resident traveling as quick as possible. Based on these results from studies, various station's accessing functions are defined and spatial arrangement of different types of connecting facilities are planned as a whole. There will be mainly five ways and means: ................................... 410  (1)  Pedestrian access................................................................................................................. 410  Walk will be the final form for all accessing ways. The walk accessing system shall be first considered for all stations. A continuous, safe and comfortable pedestrian system shall be provided through squares, crossing-street facilities and foot paths based on the passenger flow to be accessed, considering road building and rebuilding. The barrier-free facilities shall be provided for and attached to the pedestrian system and be constructed together with the urban facilities. ................... 410  (2)  Cycling access..................................................................................................................... 410  In view of the accessing features at difference areas along the subway route where most are residential areas, the cycling access is inevitable and planning of parking lots along the entire route shall be focused on whether it is convenient to access to residential areas. The accessing facilities shall be designed and distributed based on whether the land supply is possible and reasonable, and land will be reserved in view of the change in long/near term demand. The parking space will be reduced through parking space landscaping, sharing it with public buildings, three-dimensional parking, reducing space for a single cars. For the cycling accessing facilities, passengers will be encourage to use it more frequently. Specific bicycle parking space will be arranged to reduce the time percentage of bicycles using roads as much as possible. ...................................................................................... 410  (3)  Access to bus stops ............................................................................................................. 410  At the old urban areas where there are more public transports, the spatial position, the manners and the spatial size of the intermediate stops will be optimized by analyzing the bus flow route, defining the main passenger flow direction and centering arrangement of the entrance and exit of railway transit. At other areas where the public transport is developing, public transports shall be planned and developed in consideration of the subway stations along its route. Bus stops shall be optimized and adjusted to proper positions while consideration shall be given to the intersections are coordinated as a whole to meet the requirement to connect subways efficiently........................................................... 410  (4)  Taxi access .......................................................................................................................... 411  The regulations on design and arrangement of taxi facilities shall be complied and road and general traffic conditions at different areas shall be taken into consideration. Taxies are allowed to pull over the road around the subway route to take or drop passengers, for instant stopping and leaving. At the peripheral areas towards the south and the north, where conditions permit, taxi waiting space or taxi-beckoning stops will be set, and the passenger-waiting space will be set at the hub station, flexibly. ............................................................................................................................................... 411  (5)  Car access ........................................................................................................................... 411  Car access shall be planned and arranged in compliance with the criteria of "P+R" (Parking and Transfer), based on the station land condition, the road network conditions and the traffic condition, and considering the whole picture of the railway network. In the process of preparing the detailed regional planning, focus shall be on reserving parking space around the remote subway stations..... 411  12    The above-mentioned access space for public transport will be controlled and reserved as the accessing land by the planning bureau to avoid being used by other projects. During the project construction, the Subway planning company and the commission for communication will take the lead to organize the public transport companies and the gardening &landscaping organizations to build respective facilities to be accessed to the subway stations as per the planning. ........................ 411  Example: Erqi Square Station - the transfer station between Subways #1 and #3. ............................. 411  (1)  Traffic around the station .................................................................................................... 411  The station is located at the intersection of Jiefang Road and Zhengxing Street and arranged in transmeridional way along Jiefang Road. Passengers can transfer between Subway #1 and #3. There are totally 5 entrances/exits for Subways #1 and #3 which are distributed on four sides of the intersection between Jiefang Road and Zhengxing Street. The station stand at the center of the old urban area where it is well-developed, densely populated, the most prosperous commercially and highly-concentrated with urban functions........................................................................................... 411  At present, Bus Line No. 6, 603, 28, B17 have stops on Jiefang Road (stop name: Erqi Square bus stop) which are closer to the subway entrance/exit while Bus Line No. 105 (south), 806, K906, 95, 32, 21, K6, K903, 93, 517 and 906 have stops at Zhengxing Street (stop name: Erqi Square bus stop) that intersects Jiefang Road, which also are closer to the subway entrance/exit. ...................................... 411  (2) Passenger flow features ................................................................................................................. 412  The passenger flow is dominantly mixed including travellers and commuters. The passengers walking to the station are distributed over the commercial space around it. Since railway transit stations concentrate there, most passengers from other stations also walk inside it and so there will be no bicycle parking space. passengers coming to it by public transports are by passing-by buses and the train station. ........................................................................................................................................ 412  (3) Improve the integrated traffic network .......................................................................................... 412  Consideration is mainly given to access to the station on foot, by public transport, by bicycle, taxi, and private cars. ......................................................................................................................................... 412  The pedestrian system: Since the on-foot passenger flow comes from every direction around the station, squares are to be built around every entrance/exit of the subway and to be connected with established roads, and the established roads with footpath width less than 3 m will be rebuilt. Develop and improve sound planar crossing-street facilities and crossing-street facilities for transferring bus stops to provide a safe and comfortable on-foot system for on-foot and transferring passengers to the station. ................................................................................................................................................. 412  The public transport facilities: 2 bue stops on the west street will be reserved. 2 bus stops on Shuncheng Street will be relocated in order to minimize the distance from new stops to the subway entrance/exit, thus reducing the transferring time. .............................................................................. 412  The bicycle parking space: based on the demand from bicycle access and the organizational requirement, the first measure is to build more cycling roads and the second measure is to build 2 bicycle parking lots somewhere around the subway entrance/exit on the western street in order to reduce the frequency of bicycles crossing street effectively and lower traffic interference. The total area of both bicycle parking lots is 500 square meters including No.1 bicycle parking lot of 200 m2 to be located on the north side of the western street to serve the passenger flow on the north side of the station and No.2 bicycle parking lot of 300 m3 to be located on the south side of the western street to serve the passenger flow on the south side of the station; ............................................................... 412  13    Taxi: Taxies are allowed to pull over the road around the subway entrance/exit for instance stopping and leaving to provide convenience to transferring passengers on the condition that the Zhengzhou rules concerning taxi management are met. ........................................................................................ 412  2. Organize passenger flow effectively and efficiently Understand how the passenger flow changes dynamically and take some measures to manage passenger flow (e.g. restrict traffic flow and direction at the peak hours). ............................................................................................................................... 413  3. Optimize the emergency response plan The organization responsible for operating the railway transit shall prepare emergency plans to address possible situation due to high passenger flow at the peak hours to incorporate relevant organizations, establish the interactive mechanism and carry out periodical drill. .................................................................................................................................... 413  6.3.2.2 Mitigation Measures of Sensitive Points Affecting by 2 Wind Pavilions at the Same Time .. 413  6.3.2.3 Mitigation Measures of Cumulative Impact by the Vibration of 2 Subway Lines at the Same Time .................................................................................................................................................... 413  6.4 Summary ............................................................................................................................... 413  7 Analysis of alteranative schemes ..................................................................................................... 415  7.1 Analysis of Zero Scheme ...................................................................................................... 415  7.2 Comparison and Selection of the Route Selection Technology of the Project ...................... 416  7.2.1 The Principles of Route Selection .............................................................................. 416  7.2.2 Comparison and Selection of Typical Lines............................................................... 416  7.2.2.1 Comparison and Selection of Line Trend at the North of the North Ring .............................. 417  Fig.7.2-3 Line diagram of Jiangshan Road scheme ............................................................................ 418  Fig.7.2-4 North extension line plan of Jiangshan Road scheme ......................................................... 419  Fig.7.2-5 Photo of current status of north extension of Jiangshan Road ............................................ 419  Fig.7.2-6 Line diagram of Changxing Road scheme .......................................................................... 420  Fig.7.2-7 North extension line plan of Changxing Road scheme ....................................................... 420  Fig.7.2-8 Photo of current status of north extension of Changxing Road ........................................... 421  7.2.2.2 Comparison Selection of Line from Jinshui Road Station to Seven Feb.

radial rail backbone line from northwest to southeast in the city’s center. The north end of the Phase-1 project of Line 3 will start from Xinliu Road Station at the provincial sports center in Huiji District, and the south section will end at East Hanghai Road Station at the Economic Development Seventeenth Street in the Economic Development Zone. The length of the line will be about 25.2km, all underground, with 21 stations, one car depot and one parking lot. The line will be constructed along Changxing Road, Nanyang Road, Minggong Road, Jiefang Road, West Street, East Street, Zhengbian Road, Nandu Road and Economic Development Seventeenth Street, and will connect the Feb 7 Square’s Commercial Center, Economic Development Zone’s center and other urban functional centers. The line’s average station spacing will be 1.29km, and its length will be about 25.2km, with 21 stations, one car depot and one parking lot. 1.1.2 Project Origin As the provincial capital of Henan Province, Zhengzhou City is located in the hinterland of the Central Plain, with "an important hub controlling advantageous positions." Zhengzhou is always one of China’s important transportation and communication hubs, an important city of the new Eurasian Continental Bridge, and a national open and historical and cultural city. Zhengzhou is an important center city of the central region, the first city in Henan province and the urban agglomeration in the Central Plain, has unique and important geographic conditions, and is Henan Province’s political, economic and cultural center. Zhengzhou City has a long history. The Shang Dynasty had its capital here. It is the birthplace of the Chinese Civilization and one of China’s oldest cities. Its north is near the Yellow River, its southwest is hilly land, and its southeast is a vast plain. In the pattern of China’s economic development, it has an important role in linking the east and west, north and south. Zhengzhou now has under its jurisdiction six districts, five county-level cities, one county and two state-level development zones. The city's total area is 7446.2 square 1    kilometers. In recent years, Zhengzhou’s economic construction and development is rapid. Throughout 2011, Zhengzhou completed 491.27 billion yuan of GDP, ranking 20th among Chinese large and medium-sized cities, and the annual general budget revenue of its local fiancé was 50.23 billion yuan, ranking 17th among Chinese large and medium-sized cities. With the rapid development of the city, Zhengzhou presents such problems as population growth, the rapid growth of its motor vehicles, traffic jams and so on. Although, in recent years, Zhengzhou has been increasing investment in the construction of its urban traffic, the increase of its traffic supply is still far less than the growth of its traffic demand and its traffic supply and demand contradiction has an intensifying momentum. To solve the problem of metropolitan traffic congestion, the general experience of domestic and international cities is to build rapid rail transit systems and construct integrated transport systems so as to solve traffic pressure and promote cities’ healthy development. To this end, in September 2000, Zhengzhou began the preparation of the planning of its urban rail transit lines and networks. In 2004, according to Zhengzhou’s overall urban planning-related local adjustment program and to experts’ review comments, the planning of Zhengzhou’s rail lines and networks experienced a local adjustment. In August 2005, the Henan Development and Reform Commission organized and convened an experts’ review meeting on Zhengzhou City’s urban rail transit construction planning. The meeting proposed an opinion of further optimizing the forward line and network solutions. In January 2006, Zhengzhou’s rail transit construction plan was completed. In January 2008, in Zhengzhou, the China International Engineering Consulting Corporation (CIECC) organized and convened an evaluation meeting for "Zhengzhou City’s Rapid Rail Transit Construction Plan"; in March, the CIECC completed an assessment report and submitted it to the National Development and Reform Commission. In April 2008, in Zhengzhou, the Ministry of Environmental Protection organized and convened an experts’ review meeting, comprehensively reviewing and passing in principle the "Environmental Impact Report for Zhengzhou City’s Rail Transit Lines and Networks Construction Planning." In February 2009, the National Development and Reform Commission printed and issued the "Circular of the National Development and Reform Commission Regarding the Request for the Examination and Approval of the Recent Construction Plan (2008 ~ 2015) for Zhengzhou’s Urban Rapid Rail Transit" (NDRC Basic Document No. [2009] 369.). According to the construction plan, the Phase-1 project of Line 1 for rail transit started in June 2009, and the Phase-1 project of Line 2 started in December 2010. Meanwhile, in order to coordinate the construction of Lines 1 and 2, do a good job of the 2    reserved projects and provide technical support, the Zhengzhou Rail Transit Office organized and carried out the preliminary study of Lines 3, 4, 5 and 6, so as to provide a technical resource guarantee for along-the-line land use control planning, urban construction and the interim construction plan. In July 2009, the Zhengzhou Rail Transit Office entrusted relevant units to formulate and complete the pre-feasibility study report (draft for review) for Line 3 project of Zhengzhou’s rail transit, which passed experts’ review. According to the experts’ review comments and related units’ opinions, the report underwent corresponding modification. In November 2009, the pre-feasibility study report (final draft) of Line 3 project of Zhengzhou’s Rail Transit was completed. In 2010, in order to maintain the sustainability, feasibility and rationality of Zhengzhou’s rail transit construction, give play to the overall efficiency of Zhengzhou’s rail transit lines and networks as soon as possible, accelerate the process of building rail transit, and provide the construction basis for the follow-up projects of its rail transit, Zhengzhou started the preparation of "Zhengzhou City’s Rail Transit Construction Plan" (2013 - 2020). Currently, this planning report has been basically completed, initially having the conditions for being reported to a higher body. . Combining with the progress of the original construction plan and with Zhengzhou’s recent years’ development, this plan proposes that after the phase-1 projects of Line 1 and 2, the Phase-2 project of Line 1, the Phase-2 project of Line 2, the Phase-1 project of Line 3, the Phase-1 project of Line 4 and Line 5 be constructed. Among them, the project of Line 3 will be constructed in 2014 and will be completed and opened to traffic in 2016. In October 2010, in order to coordinate the formulation of its rail transit construction plan and to carry out in advance the research work for the relevant lines, the Zhengzhou Rail Transit Office entrusted the Beijing Urban Construction Survey and Design Institute to carry out the feasibility study work for Line 3 project for Zhengzhou’s rail transit. In 2012, the institute completed a first draft feasibility study report. This EIA report is based on this first draft. The Line 3 project of Zhengzhou City’s rail transit was included in the projects using the World Bank’s loans in 2011, which needed preparing an EIA report, environmental impact assessment summary and environmental management plan (ESMP) and other documents in line with the World Bank’s requirements. After accepting the entrustment, our unit organized experienced EIA staff members to undergo field research and collect the information and data related to the project, and completed the preparation of this report in December 2012. 3    1.1.3 Project Development Objectives (1) The construction of this project will not only provide safe, efficient, fast and comfortable transport for the residents along the line and will be of great significance in promoting the rational distribution of the city, accelerating the formation of urban planning, improving transport structure, protecting the ecological environment, creating a favorable investment environment, accelerating economic development, etc. At the same time, its completion will have a strong pull effect on the project’s along- the-line comprehensive development, land appreciation and so on.

One core: including the central area and three outside groups (the group of Zhengbian area - Zhongmu County, group of Airport, group of Shangjie District - Xingyang County). Four cities: referring to the four medium-sized county-level cities including Gongyi City, Xinzheng City, Xinmi City and Dengfeng City. 48    Two axis areas: the east-west axis area comprised of central Zhengzhou city, Zhengbian - Zhongmu group, Shangjie District - Xingyang group, Gongyi City and the towns and small cities, all of which are located along such arterial traffics as Lianyungang-Huoerguosi Expressway and Lianyungang-Lanzhou Railway; the north-south development axis comprised of central Zhengzhou city, Airport District group, Xinzheng City and towns, all of which are along arterials traffics like Beijing-Hongkong - Macao Expressway and Beijing-Guangzhou Railway etc. One stripe area: the east-west development stripe constituted by cities and towns like Dengfeng city area, Xinmi City area and Xinzheng City area etc. along the provincial-class arterial traffics. Figure 2.7-1 Zhengzhou City Space Layout The future nature and size of Zhengzhou City require a modernized comprehensive traffic system suitable for the modern life which is in alignment with the overall urban development level. Hence, it’s a necessary trend to build the public transport network centered on rail transit with large and medium passenger capacities, which is essential to the sustainable development of urban transportation. Such works as the formation of new urban space structure, redistribution of the population and land expansion depend on the strong support of transportation infrastructure system. According to the current urban situation of Zhengzhou, density populated regions are concentrated in several areas, the land expansion speed being greater than the population growth rate though. The phenomenon is caused largely by the existing traffic system failing to satisfy the city’s expanding needs in operation characteristics and service levels etc. Take Zhengdong New District for example, after nearly ten years’ development, it’s still haunted by problems like slow development speed, weak commercial atmosphere, poor supporting facilities and few employment posts etc., which hinder its functioning in leading Zhengzhou’s leapfrog development and bearing regional service responsibilities; and here we cannot neglect the contribution of lacking convenient transport communications between the new district 49    and old district, CBD and Erqi Square. The urban rail transit will provide fast and convenient communications for the medium-distance travels within city scope, being the important transport line connecting central cities and outside groups as well as the connection among outside groups; it will cover major functional centers and passenger flow channels of the city, supporting and leading the urban space development. The Line 3 project connects the commercial center of Erqi Square, the old city areas and Zhengdong New District, providing powerful transportation support for Zhengzhou’s development and being coordinated with Zhengzhou City overall planning. 2.7.2 Analysis on consistency with the construction planning (1) Overview of the rail transit construction planning Zhengzhou city government began to draw up the Zhengzhou Urban Rail Transit Construction Planning (2013-2020) in 2010 in order to ensure the continuity, feasibility and reasonability of the construction work, bring the rail transit network into realization as soon as possible, speed up the construction process and provide construction bases for the follow-up projects. The planning has passed the assessment by China International Engineering Consulting Corporation now. Combined with the progress of original construction planning and the recent development situations of Zhengzhou City, the current planning progress that the second-stage projects of Line 1 and Line 2 and the first-stage projects of Line 3 and Line 4 as well as Line 5 shall be put into construction after completing the first-stage projects of Line 1 and Line 2; the first-stage project of Line 3 will start in 2014 and come into use in 2016. 50      Figure 2.7-3 Line Sketches of the Second-stage Construction Planning (2013-2020) (2) Analysis on conformance to the construction planning The line designing conforms strictly to the Zhengzhou Urban Rail Transit Construction Planning in terms of line routes, laying methods, car depots and parking lot set-up etc., therefore it’s consistent with the construction planning. 2.7.3 Analysis on consistency with environmental impact assessment According to the Environmental Impact Law (EIA), the construction office entrusted Transport Planning and Research Institute of the Transport Ministry with the environmental impact assessment on Zhengzhou Urban Rail Transit Construction Planning (2013-2020) in December, 2010. Now the planning has got appraised by the expert review which is organized by the assessment center of environmental protection ministry. Main contents related to Line 3 in planned environmental impact assessment: “Since the first-stage project of Line 3 is planned to go through Erqi Memorial Tower, the line location and burial depth in the passing section of Line 3 shall be optimized in consideration of the anti-vibration distance of historic buildings and it’s necessary to take enough mitigation measures so as to eliminate adverse impacts on historic architectures.” In March 2010, the Protection Scheme of Erqi Memorial Tower Passed Through by the Rail Transit Project of Zhengzhou City from Sides was compiled by Zhengzhou Metro Limited Corporation and Zhengzhou Cultural Relics Bureau and got approval of the expert review meeting; the design and construction of Line 3 strictly comply with requirements specified in this scheme and conform to the 51    construction planning. “The noise protection distance shall be: 10m for class 4a and class 3 areas, 22m for class 2 areas and 47m for class 1 areas. And the protection distance against vibration shall be 35m when the line passes through ‘residential and educational areas’. The minimum distance between architectures above the tunnel and the tunnel outer wall should be greater than 10m so that noise impact of the underground lines on indoor secondary-structure of the architectures could be avoided. And it’s inappropriate to construct high-crowded buildings like schools, hospitals and concentrated residential buildings within areas 30m from the ventilation kiosk. In addition, the main transformer station must be away from sensitive buildings (hospitals, schools, kindergartens, densely-populated residential buildings etc.), ensuring the minimum distance being greater than 50m and away from the residential areas as far as possible; the main substation wire incoming should adopt buried cables so as to weaken the electromagnetic pollution and radio interference caused by aerial transmission lines.” The design and construction of Line 3 as well as its land utilization planning comply with the above requirements completely, therefore, the project is carried out with satisfactory conformance to the planning environmental impact assessment. 2.7.4 Analysis on consistency with regional economic and social development planning Zhengzhou has undergone a sustained and rapid growth economically and socially in recent years. Since 2000, the average growth rate of its Gross National Product (GNP) has kept 19.2%; in 2011, the urban total output value reached 491.27 billion yuan, ranking the 20th place among all medium and large cities in China; the general budget revenue of local finance for the whole year sumed up to 50.23 billion yuan, ranking the 17th; and the total retail sales of consumer goods reached 198.71 billion yuan, ranking the 19th. The large urban investment in infrastructures could break through “bottlenecks” in regional economic development, producing direct or indirect “induced investment”, which can bring about great investment benefits. According to rail transit construction experience of other cities in China, the direct contribution of rail transit construction investment to local GDP is considerable - a 100 million yuan investment can produce over 263 million yuan of GDP and create 8,466 employment posts, to say the least. The construction investments of Line 3 can not only promote social employment, but also stimulate domestic demand and play a significant role in promoting and maintaining the sustainable development of economy in Zhengzhou. Line 3 rail transit goes through the east-west development axis, covers the radial northwestern and southwestern passenger flow corridors, and connects the high-tech development district, northwestern area, Jinshui-Zhongyuan area, central urban area, new railway station area and the Economic And Technological Development Zone; 52    regions that Line 3 passes are recent priority development areas determined in Zhengzhou Overall Urban Planning (2007-2020). Construction of Line 3 is critical to urban space expansion, traffic integration, proper industrial layout and optimized spatial arrangement, carrying great significance for integrating regional resources, strengthening competitive industrials, accelerating population and industrial concentration and putting forward balanced development among regions. 2.7.5 Analysis on consistency with ecological function zoning 2.7.5.1 Analysis on coordination with the general land use policy The land use efficiency of rail transit is much greater than that of other regular ground transportations, hence, it’s capable of improving the urban land use efficiency and resource carrying capability of city infrastructures except for its function in alleviating traffic congestion and guiding the urban space layout optimization and adjustment. Developing rail transit is in accordance with “implementing the basic state policy of ‘cherish and utilize land rationally’” and the principle of land resources protection and utilization specified in Zhengzhou city overall planning - “Implement scientific development view and change land use patterns. Strictly protect arable land and basic farmland, abide by provisions on construction exclusion and restricted areas; optimize land use structures and layouts and improve the comprehensive benefits; reinforce the reclamation of industrial and mining wastelands, farmland arrangement and pollution control works, protecting and improving the ecological environment; promote coordinating urban-rural integration development, and guarantee sustainable utilization of land resources.” 2.7.5.2 Basic farmland protection The project involves no basic farmland protection areas according to Feasibility Report of Line 3 Project Site Selection and the Opinion of Land Use Pre-approval issued by the Land and Resources Bureau. 53      3 Description of the project 3.1 Construction background According to Zhengzhou Rail Rapid Transit Construction Planning (2013-2019), the government plans to start the construction work of Line 1-6 in a short term. The firs-stage projects of Line 1 and Line 2 started in June 2009 and December 2010 respectively, and the first-stage project of Line 3 is planned to begin in 2014 and come into use in 2016. 3.2 Construction necessity 3.2.1 Line 3 runs through the main development axis in the east-west direction and covers the two radial passenger flow corridors in northwestern and southwestern city areas, which has great significance for promoting the concentration and cultivation of east-west axis areas’ regional service functions, facilitating city development and playing the steering role in making appropriate urban layout. According to Zhengzhou Overall Urban Planning (2007-2020), there are four priority development areas in recent years: firstly, continue to develop the high-tech industrial development zone in Xushui groups; secondly, develop university campus park in the west to integrate with the High-Tech Industrial Development Zone; thirdly, develop Zhengdong New District in the east which is the key developing project of Henan Province and will become the new city center, and large construction projects such as the International Convention and Exhibition Center and Longzi Lake university campus park have been put into implementation planning; fourthly, build the eastern economic and technological development zone. The rail transit line 3 links the High-Tech Industrial Development Zone, northwestern area, Jinshui-Zhongyuan area, city core area, New Railway Station District and the Economic and Technological Development Zone together; the areas Line 3 passes belong to the recently prioritized developing areas determined in the Zhengzhou Overall Urban Planning (2007-2020); its construction plays an important role in accelerating the concentration and cultivation of east-west developing axis area’s regional service function, promoting city development and guiding the appropriate urban layout. 54      3.2.2 The construction of Line 3 can effectively alleviate traffic congestion in the east-west transportation corridor, relieve the traffic pressure of city center and offer convenience for people’s daily travel. The latest demographic information shows there are 2.33 million registered population and 1.2247 million floating population in Zhengzhou now, and the total population is 3.5547 million. The urban center is highly populated, which brings tremendous pressure to the city center’s traffic. And there are defects in the existing road traffic system, reflecting the contradiction between traffic supply and demand more prominently, thus traffic paralysis caused by congestion in the core city zone may occur at any time. It’s predicted that the annual passenger traffic volume of public transport in 2015 will increase to 1.6 billion person-times from the number of 0.65 billion in 2007, with an average annual growth rate of 10.5%, and the number will reach up to 2.13 billion person-times in recent years (in 2020). Without rail transit, the average travel speed in urban center will decrease to 13.5km/h in 2015, which shall bring more serious traffic congestion. Assuming the plan was executed, a cross-shaped skeleton line would have been built in 2015, which would relieve road congestion to some extent and increase the average travel velocity to 15.1km/h, effectively improving the travel efficiency. Another example, if the rail transit is not constructed, the average travel speed in core areas will decrease to 9.37km/h in 2020 and the traffic congestion problem will turn extremely severe (the average travel speed in the urban center shall be 10.9km/h). However, if the intersecting line network composed of rail transit line 1, 2, 3 and 4 has been constructed in 2020 according to the planning, the congestion problem would be largely solved with a significantly improved travel efficiency (especially the average traffic speed in city center will reach 18.7km/h, maintaining the reachable level in 2007.) 3.2.3 Construction of Line 3 is the inevitable choice for enhancing city environment of Zhengzhou, implementing sustainable development and facilitating social and economic development. Transportation acts as a guide in city development in certain cases. The urban rail transit can increase land use benefits, improve the developing intensity of lands along the line, becoming the urban land developing axis or city development axis so as to bring the planned city layout into realization. Besides, the rail transit construction can lead the formation of outer groups and satellite cities, transforming city development from the groups mode into that based on land layout of the overall urban planning. In order to lead the future urban layout effectively, the spatial and efficiency constraints reflected on omnibuses must be eliminated. It’s necessary to choose rail transit as the backbone of public transport system for its characteristics of high speed, large capacity, small land occupation and no pollution, so as to widen the developing framework of Zhengzhou city, enlarge city size, and realize the strategic objective of transforming 55      Zhengzhou from the provincial capital into a national regional central city. Therefore, the construction of Line 3 project is extremely essential. 3.3 Project overview 3.3.1 Project construction scale Line 3 is a northwestern - southeastern slant and radial backbone line in the city center. The first-stage project starts in the north from Xinliu Road Station of Provincial Sports Center in Huiji District and ends in the south at East Hanghai Road Station of Jingkai 17th Avenue in Economic and Technological Development District; the total length is about 25.2km with 21 stations, 1 car depot and 1 parking lot, and the whole line is underground.

Construction Site (1) The layout of a construction site should make full use of a station’s building land, 78      and as far as possible, combine development plots, green belts, squares, etc, which will be used as temporary construction sites, but should be subject to consent of the municipal environmental protection and planning departments. For a location whose site layout is difficult and whose traffic volume is smaller, after a traffic police department’s approval, its roads may be temporarily closed or part of its roads may be occupied as a construction site. (2) The construction site for an underground station normally will take about 25 thousand square meters. Each station’s geographical location is different, with a different environment and a different construction method, and some construction sites are relatively concentrated, and some are more dispersed, which requires that a construction team’s comprehensive ability be stronger and its construction management level be higher. (3) A shield shaft should be used as the assembly shaft and construction-related earth-going shaft of a shield. (4) In order to ensure the smooth progress of the work of laying tracks, the track laying for the Phase-1 project of Line 3 should have two track panel bases at the car depot and parking lot to facilitate the track-laying operation. 3.3.14.2. Earthwork The total amount of earthwork of Zhengzhou’s Metro Line 3 will be approximately 4,974,000 cubic meters, of which the station excavation will be approximately 2,661,000 m3, and filling will be 293,000 m3; the interval shield soil excavation will be approximately 531,000 cubic meters, and the filling will be approximately 58,000 cubic meters; the Xinliu Road station’s car park’s dredging excavation will be a total of 120,000 cubic meters, and the filling will be 279,000 cubic meters; Hanghai East Road’s car depot’s excavation will be about 393,000 cubic meters, and the filling will be about 638,000 cubic meters. In this project, the total cut will be 3,705,000 m3 and the total fill will be about 1,269,000 m3 all of which will come from the cut.For the earthwork quantity of the project of Line 3, see Table 3.3-8.

It plays an important role in bridging the east and the west of China, and is one of the core cities that promote the rise of central China. Zhengzhou, the capital of Henan Province, is the political, economic and cultural center of Henan Province. It is located in the north-central part of Henan Province, south of the Yellow River, east of Songshan Mountain, northwest of broad Huanghuai Plain, between 112°42‟E and 114°14‟E, and between 36°16‟N and 34°58‟N. It is 166km from east to west and 75km from north to south. Zhengzhou is 25km south from the Yellow River, 760km north from Beijing, 514km south from Wuhan, 570km east from Lianyungang and 480km west from Xi’an. Zhengzhou has one county (Zhongmu County), five county-level cities (Gongyi, Xingyang, Xinmi, Xinzheng and Dengfeng) and six districts (Zhongyuan, Erqi, Guancheng, Jinshui, Shangjie and Huiji, among which Shangjie District is an exclave). Its total area is 7446.2km2, among which urban area accounts for 1010.3km2 and built-up area was 328.6km2 (including Shangjie District 26.6km2) at the end of 2008. At the end of 2009, total population of Zhengzhou was 7,521,000 and urban population was 3,331,000. Green coverage ratio of Zhengzhou is up to 35.5%, so it is honored as “Green City in Central Plains of China”. Jingguang Railway and Lianyungang-Lanzhou Railway intersect here. Therefore, it is one of the important railway terminals in China. 4.1.2 Landform (1) Landform of the city Zhengzhou is located in extension of eastern section of Qinling Mountains and in the transition zone between the second class landform sidestep and the third class landform sidestep. The overall topography is higher in the southwest and lower in the northeast. The topography steps down in the form of ladder from structural erosion middle-low mountains in the west and the southwest to structural denudation hills, loess hills, inclined plains (downland) and alluvial plains which form relatively complete geomorphologic sequence. Mountains in Zhengzhou occupy area of 2377km2 which accounts for 31.9% of total 81      area. Average altitude of mountain land is between 400m and 1000m. The highest point is main peak of Shaoshi Mountain (Yuzhai Mountain) with the altitude of 1512.4m. Hills are distributed in the west of Jingguang Railway and in front and in the north of Songshan Mountain. Hills in Zhengzhou occupy area of 2255km2 which accounts for 30.3% of total area. Altitudes of most hills are between 200m and 300m. Undulating degree of hills is relative small and the land exploitation potential is relatively large. Plains can be divided into two parts, i.e. east plains and west plains. The east plains are located in the south of alluvial fan of the Yellow River and are mainly distributed in central area of Zhengzhou, Zhoumu and Xinzheng. The west plains are located in two sides of downstream of Yiluo River and Kuhe River and are distributed in Gongyi and Xingyang. Plains in Zhengzhou occupy area of 2815km2 which accounts for 37.8% of total area. The lowest point of Zhengzhou is in Shaogang of Zhongmu with the altitude of 75m. In plains, topography is flat, the soil is thick and water is adequate. Therefore, the plains are the main crop areas of Zhengzhou. (2) Landform along the project Line 3 of Rail Transit of Zhengzhou is located in central zone of Zhengzhou and belongs to plain area. The line mainly passes through municipal roads and green land. Elevation of the whole line is between 86.70m and 103.10m. Based on geological data of Zhengzhou, the line mainly passes through two geomorphic units. Geomorphic unit between start point of the project and the inter-junction of the line and the Lianyungang-Lanzhou Railway is alluvial-diluvial plain of the Yellow River (area A). Geomorphic unit between East Hanghai Road and the end of the line is alluvial-diluvial plain of the Yellow River and the micro-topography is aeolian sand dune. 4.1.3 Climate and weather Zhengzhou belongs to continental subtropical monsoon climate, so change in temperature is large. In summer, it is hot and rainy; in winter, it is cold and dry. Zhengzhou has four distinct seasons. Annual average temperature is 14.9℃. Average temperature in July is 27.8℃, and extreme highest temperature is 43.3℃. Average temperature in January is -0.3℃ and extreme lowest temperature is -17.9℃. The annual average rainfall is 640mm and the most rainfall is in summer. On record, the maximum rainfall is 866.8mm and the minimum rainfall is 439.3mm. Maximum snowfall thickness is 150mm and maximum thickness of accumulated snow is 230mm. Maximum freezing depth is 270mm. The annual average evaporation is 2048.8mm, maximum evaporation is 341.4mm in June and minimum evaporation is 80.5mm in January. October to April next year is frost period. In plain area, frost free period is more than 200 days. Throughout the entire year, northeaster and southeaster prevail 82      with average wind velocity 2.5m/s and maximum wind velocity 24m/s. Maximum sunshine hours are 4430.7h and average sunshine hours are 2189.5~2352.2h. 4.1.4 Engineering geology 4.1.4.1 Engineering geology of Zhengzhou city proper Zhengzhou city proper is covered by quaternary loose deposits. Outcrops are middle Pleistocene, late Pleistocene and Holocene series stratum of quaternary. (1) Middle Pleistocene series stratum (Q2) Middle Pleistocene series stratum is divided into middle Pleistocene series aeolian deposit, alluvium and diluvium. Aeolian deposit is mainly distributed in hills and rolling plains without outcrop. A layer of grit stone lens can be seen at the bottom of the stratum and light loam and loam in upper part of the stratum. Alluvium and diluvium are mainly distributed in inclined plains and flood plains without outcrop and are covered by late Pleistocene and Holocene series stratum. Buried depth of roof is 15-50m and thickness is 10-70m. The lower part is fine sand, medium-fine sand and gravel layer; the upper part is clay, loam and light loam. (2) Late Pleistocene series stratum (Q3) Late Pleistocene series deposits are widely distributed in Zhengzhou city proper. Except for northeast of Zhengzhou, almost all outcrops are late Pleistocene series stratums. Late Pleistocene series aeolian deposits are widely distributed in hill downlands and rolling plains in the southwest. The top layer is dark brown paleosol (thickness about 1m). The lower layer is composed of light loam and loam. Late Pleistocene series alluvium and diluvium is distributed in surface layer of rolling plains. In the northeast, alluvium and diluvium are covered by Holocene series deposit with the thickness of 15-45m. The lower part is light loam, loam mixed with find sand, medium-fine sand and grit stone lens with thickness of 5-8m. The middle part is almost loam with thickness of 5m. The upper part is light loam as primary and loam mixed with sand lens as supplementary with thickness of 10m. There is a layer of breen loam with thickness of 1m at the top layer. (3) Holocene series accumulation (Q4) It is distributed in flood plains and valleys in the east. It can be divided into three types, alluvial, aeolian and artificial accumulation. The artificial accumulation is mainly distributed in old city zone of Zhengzhou with thickness of 0.5-7m. 4.1.4.2 Engineering geology along the line Based on geomorphic units and geotechnical properties along the line of the project, engineering geology along the whole line 3 is divided into two districts, i.e. district A 83      and district B. Zone A: the range is from start point, through Nanyang Road, Erqi Square, Dongdajie Street and Zhengbian Road, to inter-junction of the line and Lianyungang-Lanzhou Railway. The mileage is K0+0.000~K23+200. Elevation of the ground is between 86.70m and 103.10m. Zone B: the range is from inter-junction of the line and Lianyungang-Lanzhou Railway to the end point. The mileage is K23+200~K31+350.000. Elevation of the ground is between 87.10m and 95.00m. Geomorphic unit of Zone A is alluvial-diluvial plain of the Yellow River. Stratum of the site within depth of 30m is mainly the Q4 Stratum. As to stratum of the site within 0-19.0m, the surface layer is artificial fill and miscellaneous fill and the lower layer is slightly dense and medium dense silt soil, and soft plastic and plastic silty clay mixed with silt sand and fine sand. Main stratum of 19.0-30.0m is medium dense and dense silt sand, fine sand and medium sand layer. The stratum under the depth 30m is Q3 and earlier one. It is mainly hard plastic silty clay and dense silt soil and find sand layer. Geomorphic unit of Zone B is alluvial-diluvial plain of the Yellow River and micro-topography is aeolian sand dune. Stratum of the site within depth of 30m is mainly the Q4 Stratum. As to stratum within 0-15m, the surface layer is artificial fill and miscellaneous fill and the lower layer is medium dense fine sand and silt soil mixed with thin silty clay. Main stratum of 15-33m is medium dense and dense fine sand layer. The stratum under the depth 33m is Q3 and earlier one. It is mainly hard plastic silty clay and dense silt soil and find sand layer. 4.1.5 Hydrogeology 4.1.5.1 Characteristics of aquifer system Groundwater types of Zhengzhou can be divided into clastic rock fissure water and loose rock pore water which are mainly and widely distributed groundwater types in Zhengzhou. The groundwater types and water yield property distribution figure are as shown in figure 4.1-1. 84      Figure 4.1-1 Groundwater types and water yield property distribution of Zhengzhou Based on buried depth, hydraulic properties and exploitation condition of groundwater, Quaternary groundwater can be divided into shallow groundwater and mid-deep groundwater. (I) Shallow aquifer system Shallow groundwater generally refers to concealed water and micro confined water with the buried depth less than 60m. The zonation is clear. It covers from mountains 85      to alluvial plains. The particles are from coarse to fine. The water yield property depends on lithology and thickness of aquifer. Buried depth of bottom of shallow aquifer system is 50-70m in general. Buried depth in the east is relatively large and in the west is relatively small. In the east of Jingguang Railway, it is mainly composed of upper Pleistocene and Holocene series; Yuanqian plain in the west is composed of Holocene and upper Pleistocene series; Taiyuan zone has middle Pleistocene series as primary and lower Pleistocene series as secondary. The part under shallow aquifer system is separated by loam or loam sand aquitard and underlay aquifer. Thickness of aquitard is 25-45m. Shallow water is major water supply for suburban agriculture. Based on occurrence condition, lithology characteristics can be divided into: (1) The pore water with sand and grit stone as main is distributed in alluvial plain of the Yellow River in the east of Jingguang Railway and in the north of Lianyungang-Lanzhou Railway. Aquifer is composed of one or two layers of middle and coarse sand, find sand and gravel in partial position. Buried depth of roof is 10-20m. Partial depth is less than 5m or more than 25m. (2) The sand and clay pore water is distributed in Gouzhao, Shibali River and Yuanqian alluvial-diluvial plain in Nancao zone. Aquifer is mainly composed of silt, loam, clay and loam mixed with loess doll. Partial aquifer contains find sand with thickness of 2~6.5m (maximum 16.6m). The buried depth of roof is 4.3～30m. (3) Clay and loess fissure pore water is distributed in Sanli and loess Taiyuan zone of Kuangshan Mountain in the southwest. Pore water in loess has been drained. The aquifer is mainly the underlay loam including loess doll layer. (II) Mid-deep aquifer system Mid-deep groundwater refers to confined water with buried depth of 60～350m. The particles are relatively coarse. Thickness is relatively large and water quality is good. Therefore, it is major water supply for industrial and agricultural production and urban domestic water. Mid-deep groundwater is distributed under the first stable aquiclude with the buried depth of roof 50-100m. Procuratorial College and Mazhuang Zone in the east achieve buried depth of the bottom. It is 300-380m in the east and 220-280m in the west. Aquiclude in the roof is mainly loam, sandy loam and clay with thickness of 10-50m. Aquiclude at the bottom is mainly the clay with thickness of 20-50m (maximum 80m). The aquifer system can be divided into two aquifers. Aquifer of middle Pleistocene series is composed of one or two layers and multi-layer fine sand and mid-fine sand. Partial section is composed of mid-coarse sand or silt layer. The thickness is 10-30m. Buried depth of roof increases from 50m in the southwest to about 60-80m in the northeast. The maximum buried depth is almost 100m. Aquifer of lower Pleistocene series: none in southwest; Northeast of 86      Wali-Dazhuang-Zhangweizhai is composed of 3-5m middle sand layer, mid-coarse sand and gravel. Partial section is composed of fine sand and silt. The thickness is 20-50m. Buried depth of roof increases from 70m in Yuanqian downland in the southwest to 140m in the northeast (maximum 155.5m). The structure is loose or semi-cemented. Water is abundant. It is the major exploitation target layer in Zhengzhou. 4.1.5.2 Recharge, runoff and discharge conditions (1) Recharge, runoff and discharge of shallow groundwater Shallow water of city proper and suburb is primarily from atmospheric precipitation infiltration and surrounding lateral runoff recharge and secondarily from canal infiltration and infiltration recharge of irrigation water. Shallow water near the Yellow River is primarily from lateral recharge of the Yellow River and the atmospheric precipitation infiltration. Based on relevant data, precipitation infiltration coefficient of alluvial plain of the Yellow River in the northeast is (10～20)×104m3/km2·a and of surrounding suburbs is more than 20×104m3/akm2. Ground of the city proper is hardened, so it is not benefit for precipitation infiltration and precipitation infiltration coefficient is less than 5×104m3/km2·a. Lateral seepage of the Yellow River is 8337.8×104m3/a. Infiltration capacity of Changzhuang reservoir, Jiangang reservoir, Xiliu Lake and other artificial water bodies is 1010.56×104m3/a. Topography of Zhengzhou City is high in the southwest and low in the northeast. Influenced by the topography, natural flow direction of shallow groundwater of Zhengzhou City is from the southwest to the northeast. Influenced by increased exploitation, the groundwater depression cone is formed. In the cone area, the shallow groundwater flows from surrounding area to cone center. Statistic and cruising data of buried depth of water level in July, 2008 shows (in figure 3-4) buried depth of water level in suburbs in the east and alluvial plain in the north is mostly less than 5m or 5～10m and in city proper in the east of Jingguang Railway is mostly 10～15m, in the west of Jingguang Railway 15～35m, and suburbs in the west 20～40m. 87      Figure 4.1-2 Contour line of buried depth of Quaternary shallow groundwater in Zhengzhou city proper Discharge of shallow groundwater: in early period of exploitation, evaporation and exploitation are main approaches of discharge of shallow groundwater. Secondary approaches are runoff to the east out Zhengzhou and discharge in Huaihe River. After 1970s, influenced by labor exploitation, Zhengzhou has strengthened the exploitation of mid-deep groundwater. The mid-deep groundwater which was higher than shallow groundwater is lower than shallow groundwater now, which stimulates the shallow groundwater recharging the mid-deep groundwater. There is evaporation discharge in shallow buried area of shallow groundwater in the east and northeast. Besides, there is a little river discharge and lateral discharge. (2) Recharge, runoff and discharge of mid-deep groundwater 88      Recharge of mid-deep groundwater is mainly the leakage of shallow groundwater and surrounding groundwater flowing to the cone center, among which the leakage of shallow groundwater accounts for about 80% of total recharge. Before exploitation of mid-deep groundwater, mid-deep confined water of Zhengzhou city proper flows from the southwest to the northeast. Hydraulic gradient is about 1/1500～1/2500. Influenced by exploitation, after 1970s, the exploitation has been enhanced, so the groundwater depression cone is formed and the surrounding groundwater flows to the cone center. Main discharge approach of mid-deep groundwater is labor exploitation. The lateral discharge is small. 4.1.5.3 Exploitation of groundwater resource Water supply type of Zhengzhou city proper is surface water and groundwater. There are 4 modes of water supply. Firstly, water is supplied by surface water plant and groundwater plant. Shiyuan Water Plant and Baimiao Water Plant adopt surface water of the Yellow River. Shifo Water Plant and Dongzhou Water Plant adopt groundwater near the Yellow River. Well Water Plants adopt groundwater in central city proper flowing in public water supply network. Secondly, self sufficient wells of company adopt groundwater. Thirdly, the Yellow River diversion project adopts ecological water from surface water of the Yellow River to Zhengzhou city proper. Fourthly, urban villages adopt centralized water supply from groundwater in decentralized area. According to Management Report of Water Supply, Consumption and Groundwater of Zhengzhou City Proper in 2011, the total water consumption of Zhengzhou city proper was 278,220,000m3, among which water consumption for industry was 46,160,000m3, domestic water consumption was 193,190,000m3, and water consumption for other purposes (water for fire control, free water consumption and water for buildings) was 38,870,000m3. 4.1.6 Seism According to Seismic Ground Motion Parameters Zonation Map of China (GB18306-2001), peak acceleration of seismic ground motion of Zhengzhou is 0.15g. Characteristic period of response spectrum of seismic ground motion is 0.40s. Seismic fortification intensity of Zhengzhou is 7. Classification of design seism is the second class and design basic acceleration of seismic ground motion is 0.15g. Mileage in zone A is K0+0.000~K23+200. Thickness of coverage on site is more than 50m. According to article 4.1.6 in Code for Seismic Design of Buildings (GB50011-2010), type of soil on site is mid-soft type. Classification of construction site is class III. Design characteristic period is 0.55s. Because there is little liquid soil in the line, division of anti-seismic section for buildings belongs to disadvantageous anti-seismic section. Mileage in zone B is K23+200~K31+350.000. Thickness of coverage on site is less than 50m. Classification of construction site is class II. Design characteristic period is 89      0.40s. Division of anti-seismic section for buildings belongs to advantageous anti-seismic section. 4.1.7 Animal and plant resources In Zhengzhou, there are mountains, hills, plains, eastern sand region and the Yellow River wetland with area of 34,000 hectares which provide good inhabit environment for many animals. Animal fauna of Zhengzhou belongs to north China animal fauna. Species and quantity of animals in mountains and hills in the west are more. Animal resources in forests are relatively abundant. Zhengzhou has two kinds of first class nationally protected animals (Aquila heliaca and Aquila chrysaetos) and more than 40 kinds of second class nationally protected animals (including Andrias, Cygnus cygnus and Cygnus columbianus) among which Ciconia ciconia, Cygnus cygnus, Cygnus columbianus and other aquatic birds are distributed in the Yellow River wetland and other wetlands in Zhengzhou in the centralized or decentralized way and Aquila chrysaetos, Aquila heliaca, Accipiter gentiles, Accipiter soloensis and other protected animals are distributed in mountains, hills and plains in Zhengzhou in widespread or scattered way. Cultivated area is 313,900 hectares and orchard area of Zhengzhou is 2.45 hectares. Green rate of Zhengzhou city proper is 27.8%. There are poplars, willows, chinars, locust trees, elms, kiris, pines, cypresses and other trees. Floristic division of Zhengzhou belongs to warm temperate deciduous broadleaf forest vegetation type. It crosses two vegetation zones. Area in the east of Jingguang Railway belongs to cultivated crop vegetation zone of Eastern Henan Plain. Area in the west of Jingguang Railway belongs to vegetation zone of deciduous broadleaf forest in mountains, hills and mesas. Plant resources of Zhengzhou are abundant. Main crops are wheat, corn, rice, peanut and cotton etc. Local specialties are honeysuckles in Xinmi, Chinese dates in Xinzheng, persimmons in Xingyang, garlics, watermelons and peanuts in Zhongmu, pomegranates in Heyin, tobaccos in Dengfeng and Chinese roses in Zhengzhou. There are 19 national key protected plants, including Metasequoia glyptostroboides, Ginkgo biloba, Eucommia ulmoides Oliv, Paeonia suffruticosa with spots, Pteroceltis tatarinowii, Juglansregia Linn, Pistacia chinensis Bunge, Glycine soja and Kolkwitzia amabilis Geaebn etc, which are mainly centralized in mountains in different counties and the Yellow River wetland in Zhengzhou. 4.2 Overview of social environment 4.2.1 Administrative division Zhengzhou is the political, economic and cultural center of Henan Province. It has 90      one county (Zhongmu County), five county-level cities (Gongyi, Xingyang, Xinmi, Xinzheng and Dengfeng) and six districts (Zhongyuan, Erqi, Guancheng, Jinshui, Shangjie and Huiji, among which Shangjie District is an exclave). Its total area is 7446.2km2, among which urban area accounts for 1010.3km2. According to Zhengzhou Statistical Yearbook (2012), at the end of 2011, built-up area of Zhengzhou city proper was 354.7km2, total population of Zhengzhou was 8,857,000 and of Zhengzhou city proper 4,563,000. 4.2.2 Regional economy In recent years, society and economy of Zhengzhou have continuously developed in fast speed. From 2000 to now, average annual growth rate of GNP is 20.6%. In 2011, annual total output value of Zhengzhou was 497.98 billion Yuan which increased by 13.8% that that of last year. Proportion of primary, secondary and tertiary industry was from 12.4:53.7:33.9 in 1990 to 2.7:57.7:39.6 in 2011. The secondary and tertiary industry accounted for 97.3% of total output value. At present, Zhengzhou accelerates process of industrialization, urbanization and agricultural modernization, optimizes economic structure, changes growth mode, constructs advanced manufacturing base, modern service industry center and modern agricultural demonstration district and constructs ecological Zhengzhou, peaceful Zhengzhou and harmonious Zhengzhou. Zhengzhou shall be built into a national regional central city, national important modern logistics and business city, national important transportation and communication city and national famous historical culture city. Industrial structure of Zhengzhou is gradually optimized. Industrial upgrade step obviously accelerates. Zhengzhou has obvious advantages in textile, machinery, building material, refractory material, energy and raw material industries. Therefore, four leading industries (non-ferrous metal, food, coal and cigarette) are formed. Economic development of Zhengzhou has huge potential. According to latest general plan of the city, orientation of Zhengzhou is a national regional central city, national important modern logistics center, regional finance center, advanced manufacturing base and science and technology innovation base. In 2011, total output value of Zhengzhou was 491.27 billion Yuan which was the 20th among large and middle sized cities in China; the general budget revenue of local finance was 50.23 billion Yuan which was the 17th among large and middle sized cities in China; total retail sales of consumer goods was 198.71 billion Yuan which was the 19th among large and middle sized cities in China. 4.2.3 Natural resources Zhengzhou is a city with most abundant natural resources in China. There are 36 proved mineral resources, including coal, bauxite, fireclay and oil stone. Proved reserves of coal are 7.208 billion tons, of fireclay 100 million tons and of bauxite 260 91      million tons (40% of the whole province). Natural oil stone is excellent in quality. Zhengzhou has one of largest natural oil stone bases in China. 4.2.4 Overview of transportation 4.2.4.1 Overview of urban comprehensive transportation Zhengzhou is an important transportation hub in China. With development of economy and society of Zhengzhou, transportation industry has developed rapidly. At present, Zhengzhou Railway Network is formed, and Zhengzhou Road Network and Zhengzhou Air Harbor has preliminarily taken shape. A comprehensive transportation system integrated with railways, highways, civil aviation and pipeline transportation has primarily formed. 4.2.4.2 Railways At present, as to railway hub in Zhengzhou, the pattern of Zhengzhou North Marshalling Station and Zhengzhou Railway Station in parallel has formed. Railway transportation of Zhengzhou in recent years has grown rapidly. In 2008, railway passenger volume of Zhengzhou was 26,240,000 person-trips which accounted for 9.22% of total passenger volume of Zhengzhou. In recent 5 years, average growth rate of railway passenger transportation volume is 8.3%. In 2008, total freight volume of railway was 31,080,000 tons which accounted for 8.31% of total freight volume. In recent 5 years, average growth rate of railway freight transportation volume is 4.79%. Zhengzhou Railway Station is the only large scale passenger transportation station in Zhengzhou railway hub and is one of large passenger transportation stations in China. After expansion and renovation in many times, the building area of Zhengzhou Railway Station is up to 40,000m2. Its scale and area of waiting rooms are the third in China. In Zhengzhou Railway Station, departure, arrival and passing operation and changing and hanging operation of all passenger trains in Jingguang and Lianyungang-Lanzhou Railway are provided. Capacity for the departure/arrival track of the station is 296 trains. Zhengzhou North Marshalling Station is the largest marshalling station in Asia. The marshalling station belongs to network marshalling station and bidirectional longitudinal three-class and six-yard type. Zhengzhou North Marshalling Station undertakes break-up, marshalling, arrival and departure operation of freight trains in Jingguang and Lianyungang-Lanzhou Railway and in Jiaozhi Railway (North of Xiangfan to North of Zhengzhou and Shangfu to Zhengzhou North) and provides exchange trains for Zhengzhou East Railway Station and Zhengzhou West Railway Station. Zhengzhou East Railway Station is a principal freight station in China and is established with the only comprehensive freight yard in the hub. It mainly provides 92      arrival, departure and transshipment of full-truck-load, less-than-truck-load and containers and placing-in and taking-out operation in freight yard and special lines. 4.2.4.3 Highways Highway network layout of Zhengzhou is Zhengzhou City as center, G107, G310, Lianhuo Expressway and Jingzhu Expressway as double cross framework, S102 and S103 as radial support, G207, S223, S232 and S237 vertical lines as supplementary, and S314, S315, S316, S317, S321 and S323 horizontal lines as linkage support. Above mentioned lines and criss-cross highways in counties and towns form the highway network which links trunk lines and branch lines. At the end of 2008, total mileage of Zhengzhou City highway was 12144.0km and density of network was 1.63km/km2, among which mileage of national highways was 444.2km, provincial highways 783.4km, county highways 1011.3km, town highways 3889.7km, village highways 5770.6km and special roads 244.7km. There are 10 bus stations in Zhengzhou which are public stations with area of 18.7ha. The daily passenger dispatched number is 71,300, among which 17,700 passengers go out of Henan Province, 41,000 passengers go to other places in Henan Province (excluding passengers to counties and cities under jurisdiction of Zhengzhou) and 12,600 passengers go to counties and cities under jurisdiction of Zhengzhou. The passenger volume of bus stations (Long-distance Center Bus Station, Erma Road Long-distance Bus Station, Jingguang Long-distance Bus Station and South Bus Station) near Zhengzhou Railway Station accounts for 70% of total passenger volume of long-distance passenger volume of Zhengzhou. In 2008, passenger volume of highway in Zhengzhou was 254.65 million. In recent 5 years, average growth rate is 12.5%. Highway passenger transportation is in leading position of external transportation system in Zhengzhou. In 2008, passenger volume accounted for 89.5% of passenger volume of the whole society. 4.2.4.4 Aviation Xinzheng International Airport is an aviation airport of Zhengzhou and is an important trunk airport and air hub in China. It is one of five air stations in China and is the first class air port. The airport is designed based on international standard. Aircraft movement area reference code is class 4E. Runway is 3400m in length and 60m in width and is large enough for take-off and landing of B747-400 passenger planes. Area of airdrome is 110,000m2 which is large enough for 12 large scale planes. At present, Xinzheng International Airport has offered 51 air routes and 274 scheduled flights every week. Compared with 1995, 21 air routes and 155 scheduled flights are increased. At present, it has become a modern international airport with business covering Henan and surrounding regions. In 2008, air passenger volume of Zhengzhou was 3,560,000 person-trips and freight 93      volume was 40,000 tons. During 2004~2008, average annual growth rate of air passenger volume was up to 13% and of air freight volume was up to 18.9%. Base and proportion of air traffic are small. Therefore, although growth speed is fast, the gross volume is still small. 4.2.4.5 Traffic Situation of Urban Roads Until 2008, Zhengzhou has constructed many roads with the total length of 1232.3km, including 177.4km expressway, 551.4 km arterial road, 213.2 km sub arterial road and 290.3 km by-pass. The density of road network is 4.19 km/km2. The road network structure of “ring + radiation” has been preliminarily formed. Being divided by Beijing-Guangzhou Railway and Lianyungang-Lanzhou Railway, the traffic flow in Zhengzhou is the largest in the east-west direction in the southwest quadrant and northeast quadrant. The traffic flow is decreasing gradually from the axis composed by the southwest quadrant, northeast quadrant and East New Zone of Zhengzhou to the south and north. The intensity of road network traffic is gradually decreasing. The traffic in the east-west direction is mainly concentrated on Jinshui Road, Zhongyuan Road and Longhai Road. The intensity is decreasing obviously from the trunk road to both sides and the suburban areas. The traffic flow of Zhengzhou in the east-west direction is larger than that in the south-north direction. The traffic flow of motor vehicles is the largest in the section of northeast district and southwest district; the next is the northeast district and east new district; the traffic flow is gradually decreasing from the axis of southwest district-northeast district-east new district to the south and north. In the south-north direction, the traffic flow in the northeast district and southeast district is larger. During the peak hours, the traffic flow of motor vehicles in the section of northeast district and southwest district is the largest. The two-way traffic is 16420 vehicles/h, which account for 52% of the total traffic flow crossing the Beijing-Guangzhou Railway. The traffic flow of motor vehicles in the northeast district and east new district takes the second place. The maximum peak hour flow in the section of Lianyungang-Lanzhou Railway occurs in the southeast district and northeast district. Generally speaking, the traffic flow in the urban area has obvious characteristics: 1. Divided by Beijing-Guangzhou Railway and Lianyungang-Lanzhou Railway, the traffic flow crossing the railways is large, as manifested in the overlapping part of these two railways, which is the border between the northeast district and the southwest district; 2. The throughput of motor vehicles in different sections is basically decreasing from the axis composed by the southwest quadrant, northeast quadrant and East New Zone of Zhengzhou to the south and the north; 3. The traffic flow of non-motor vehicles is the same as the motor vehicles. 94      The first phase of rail transit No.3 is a passenger transport corridor linking up the northwest and southeast of Zhengzhou. It links up the northern area, the old town, the east new district and the economic and technological development zone. This phase is basically in the urban built-up area. The surroundings of stations along this line are provided with good road network. The straight forward and intersected road conditions are good. Except the old town and the economic development zone, the road planning along this line has been basically realized. Please refer to table 4.2-1 and table 4.2-2 for roads along this line and intersected roads.

The density of bus network in the central urban area has reached to 4km/km2. Currently, the bus routes are mainly concentrated within the third ring road. The bus 96      passenger corridors include 7 in east-west direction and 8 in south-north direction. The corridors in east-west direction include Jianshe Road-Jinshui Road, Zhongyuan Road-Zhengbian Road, Dongfeng Road, Nongye Road, Huanghe Road, Longhai Road and Hanghai Road. The corridors in south-north direction include Huayuan Road－Zijingshan Road, Wenhua Road, Nanyang Road-Minggong Road. Jingsan Road-Chengdong Road, Jingguang Road, Daxue Road, Songshan Road and Dongbai Road. The structure of the current public transit network in Zhengzhou has the following characteristics: 1) On the whole, the orientation of bus routes in Zhengzhou City is in east-west direction and south-north direction; 2) The bus routes in Zhengzhou are mainly concentrated in Jianshe Road-Jinshui Road, Zhongyuan Road, Hanghai Road, Huayuan Road-Zijingshan Road, Nanyang Road, and Wenhua Road. Most of them are connected with Erqi Square and central station; 3) The density of bus roads in the east new district, economic development zone and high and new industrial district is low. (2) Overview of Buses along this Line The first phase project of Zhengzhou Subway No.3 connects the northwest and southeast of the city, and coincides with the busiest arterial road in the east-west direction. Therefore, this district is the one with the most developed urban traffic, the highest road network density, the largest passenger flow, and the most troublesome district in traffic operation and organization. The road network within the third ring road is dense. Nearly each intersection is provided with a bus station, and the distance between stations is not more than 500m. The bus stations outside the third ring road are yet to be developed. The connection between the existing bus rapid transit systems of Zhengzhou and the first phase of rail transit No.3 is not close. Only a part of B20 line is overlapping with the first phase of line No.3. The overlapping part is from Nongye Road to Minggong road along Nanyang Road. So the overlapping rate is very low. On the other hand, only B1 main line has two intersections on Nongye Road and Weilai Road with the first phase of rail transit No.3; B10, B11, B15, B16 and B19 lines only have one intersection with the first phase of line No.3; while the other 6 BRT lines are far away from the first phase. From the direction of line No.3, there is a large passenger flow from ground bus routes passing by this line, which will be the basic passenger flow and the main source of passengers.

As early as 3,600 years ago, here is the important city of Shang Dynasty. Zhengzhou once was the capital of Xia Dynasty, Shang Dynasty, Guan State, Zheng State and Han State as well as Zhou (equivalent to present province) in Sui Dynasty, Tang Dynasty, the Five Dynasties, Song Dynasty, Jin Dynasty, Yuan Dynasty, Ming Dynasty and Qing Dynasty. Zhengzhou has rich tourism resources, natural landscape, history & culture and modern civilization add radiance and beauty to each other. With long history, beautiful scenery, assembled human landscape and various scenic spots and historic sites, Zhengzhou now has 499 culture relic protection sites, 43 historical and cultural relics under state protection and 76 historical and cultural relics under provincial protection, there are also Songshan Mountain Scenic Spot mainly including Shaolin Temple, Zhongyue Temple and Songshan Mountain National Forest Park, Yellow River Historic and Cultural Scenic Spot mainly including Yellow River Tourist Area and Dahe Village Primitive Village Site, and Fuxi Mountain, Huancui Valley, Imperial Mausoleum of Northern Song Dynasty, Stone Cave Temple of Northern Wei Dynasty, Native Place of Xuanyuan Yellow Emperor and Native Place of Poet Dufu etc. 4.3 Material culture resources Three culture relic protection sites are involved in assessment range of this line, including Erqi Memorial Tower (Memorial Tower of the Great Strike of February 7, 1923), Zhengzhou Confucious’ Temple and Shang Dynasty Site in Zhengzhou. With reinforced concrete structure and built in 1971, Erqi Memorial Tower located in Erqi Square of Zhengzhou is unique and archaized conjoined twin tower in Chinese buildings, and a memorial tower built in honor of the great strike of the Beijing-Hankou Railway workers. It was listed as historical and cultural relics under state protection in 2006 and is the youngest historical and cultural relics under state protection in China. With reinforced concrete structure, Erqi Memorial Tower is 99      double-body tower in parallel connection with total height of 63m and 14 stories, of which tower base has 3 stories and tower body has 11 stories. Apex angle of each story is archaized jet angle cornice and green glazed tiles cover the top. Belfry is built on the top of the tower, six large bells with diameter of 2.7m tell time by playing music of “The East Is Red”. One red five-star is placed on the belfry. Tower plain is two pentagons with east-west connection, and it is single tower from the east-west direction and twin tower from north-south direction. Erqi Memorial Tower is now called Erqi Memorial Hall. There are 10 tower-story halls and 1 underground hall in the Memorial Hall, displaying various historical relics, pictures and written materials of the Great Strike of February 7, 1923 in the tower. Erqi Memorial Tower is the landmark building of Zhengzhou, the minimum horizontal distance between Line 3 rail and Erqi Memorial Tower is only 3m, and protection state of Erqi Memorial Tower is good. Zhengzhou Confucious’ Temple was founded in Yongping Period of Eastern Hanming Emperor reign, built on a large-scale in the third year of Qianlong Emperor Reign, and fired in the second year of Guangxu Emperor Reign. Dacheng Hall of Qing Dynasty survived after liberation, due to large historical, artistic and scientific values, it was listed as historical and cultural relics under provincial protection by People’s Government of Henan Province in June, 1963. People’s Government of Zhengzhou City allocated 30 million yuan to build 18 palaces and temples including over 80 rooms with area of about 9,333m2 from 2004 to 2006, large timber frames all adopted solid wood structure, tiles for roof all adopted traditional tiles, black bricks were laid in yards, details for building components adopted traditional wood carving, stone carving and tile carving, and reserved Dacheng Hall foundation in Ming Dynasty, Qing Dynasty and the period of the Republic of China. Dacheng Bell with weight of 2557 Jin (1278.5kg) is hung in front of Dacheng Hall in Confucious’ Temple, meaning that confucius’ birthday of 2557 years, Ceremony of ringing the bell was held at night of December 31st, 2006, marking bell tone of Confucious’ Temple which disappeared for over 100 years ring again. The minimum distance between Line 3 rail and Zhengzhou Confucious’ Temple is about 82m, and protection state of Zhengzhou Confucious’ Temple is good now. The ruins of middle Shang Dynasty’s capital. It’s located both within Zhengzhou city and in the suburb, being basically a square and covering an area of about 25km2. Uncovered in 1950, the ruins belong to Shang-Dynasty rammed earth construction. The city wall has a ladder-shaped profile, built with foundation trench under and protection slope at the two sides, all of which are constructed with rammed earth by section and layer. There are dense rounded pointed-bottom or rounded circular-bottom ramming trails on each layer of earth, and the city wall is also imprinted with board building marks. The whole city wall is about 7km in circumference, including the 1690m length of north wall, about 1870m length of west wall and the two 1700m lengths of south and east walls. The width of wall foundation is approximately 20-32m, and the maximum height of remaining foundation on the ground is about 5m. Historical relics unearthed from the ruins are mainly earth wares and bronze wares etc. 100      The ruins were announced as historical and cultural relics by the People’s Government of Henan Province on August 1956 and later named as historical and cultural relics under state protection in 1961 by the State Council. Since the ruins are close to city constructions and isolation protection measures for the site outskirts are insufficient, there still exist destructive phenomena like citizens damaging the rammed earth, digging holes and climbing etc. The distance between line 3 rails and the ruins is about 6m. 4.4 Current situation of environmental quality 4.4.1 Current situation of quality of air environment Ambient air quality of Zhengzhou city area in 2012 reached Level III standard; ambient air quality of four county-level cities and one county including Xinmi City, Xinzheng City, Xingyang City, Dengfeng City and Zhongmu County reached Level II standard, and that of Shangjie District reached Level III standard.

In recent years, Zhengzhou has gradually rebuilt Jinshui River, Dongfeng Canal and Xiong’er River into Riverfront Park with area of 231.08hm2, 20 squares with area of 116      62.23hm2 have been built, including Lvcheng Square, Jingwei Square, Zijing Square, Lvyin Square, Wenhua Square, Wenbo Square and Weilai Square; 17 street parks and green areas with area of 26.97hm2 have been built, including Ruhe Residential Area Park, Tongbai Road Park, Park of Affiliated Hospital of Institute of Traditional Chinese Medicine, Shangcheng Park and residential block green belt of Administrative Committee; 11 overpass green areas with area of 46.78hm2 have been built, including Zijingshan Overpass greenbelt, Xintongqiao Overpass greenbelt and Dashiqiao Overpass greenbelt; Shang Dynasty Site greenbelt is being built at wall of ancient city in light of conservation of historic cultural city and by exploring Central Plain cultural essence. Construction and production of garden and nursery stock in Zhengzhou is mainly of state-owned nursery garden, supplemented with enterprise nursery garden and a few collective and individual nursery gardens. At present, Zhengzhou has productive plantation area of 405.81hm2, accounting for 3.13% of urban built-up area. Zhengzhou has green area for environmental protection of 22.94hm2, including 15.68hm2 for Jinshui District, 4.48hm2 for Guancheng District and 2.78hm2 for Gaokai District, and they are mainly protection forests along railways (Beijing-Guangzhou Railway and Lianyungang-Lanzhou Railway) and rivers (Dongfeng Canal and Xiong’er River). Among greening tree species in Zhengzhou, deciduous tree mainly includes Paulownia elongata, populus tomentosa, Platanus acerifolia (Platanus orientails), Robinia pseudoacacia and Chinese scholartree etc.; aiphylium mainly includes oriental arborvitae, cedar, Chinese pine and glossy privet etc.; defoliation flowering shrub mainly includes Chinese rose, peony, winter jasmine, flowering peach, crape myrtle, Chinese redbud, flowering almond and clove etc.; evergreen flowering shrub mainly includes Chinese littleleaf box, Viburnum awabuki (sweet viburnum), moundily (Spnish bayonet), sweet-scented osmanthus, photinia serrulata and pittosporum tobira etc.; akebi plants mainly include Chinese wisteria, honeysuckle, grape, Japanese creeper and elecampane etc. Zhengzhou is located in Central Plains with long history, there are more than 1,200 old trees preserved in Zhengzhou, 17 of which are in urban area with the highest tree-age of over 500 years. Famous trees mainly include 4 cedars - Friendship Trees of Zhengzhou in China and Urawa in Japan which are planted in Bishagang Park now. 13 Friendship Flowers of Zhengzhou in China and Urawa in Japan are planted in People’s Park. Platycladus orientailis and cedar forest, Memorial Forest of the 4th conference of Central Afforestation Committee, are planted in Yellow River Tourist Area. 5 cedars, China-Japan Youth Friendship Memorial Forest, are planted in Penoy Garden of Yellow River Tourist Area. There is also memorial forest planted in Bishagang Park at annual meeting of the 14th session International Small and Medium-sized Cities. These famous and old trees in parks and institutions have fair growth potential, and Chinese scholartree and cypress in Guancheng District and Erqi District have poor growth potential since they are seriously affected by diseases and pests and human factors. 117      This project passes through Dashiqiao Overpass greenbelt and public green space of Shangyun Park in Shang Dynasty Site in the form of underground line, involving Jinshui Road Station and Chengdong Road Station, Jinshui Road Station is located at the north of Dashiqiao Overpass without occupying overpass greenbelt; Chengdong Road Station sets one passageway and one ventilation kiosk cooling tower with area of about 520m2 in Shangyun Park, most occupied land is hardened land for leisure, and public green space is not occupied basically. Lands occupied by other stations are mostly green belts at both sides of road. 4.4.6.7 Distribution of nature reserves, scenic spots, forest park and basic farmland along the Line Since this project is mostly located in urban center, nature reserves, scenic spots and forest park of Zhengzhou are relatively far away from the assessment range. According to field investigation, scenic spots, nature reserves and forest park are not involved in the assessment range along the Line. At the same time, various ecological function zones of Zhengzhou are mostly located at outer city with long distance, so current various nature reserves and forest park of Zhengzhou are not involved along the Line. According to Opinions on site location of Zhengzhou Rail Transit Line 3, this project does not involve basic farmland preservation area. 118      5 Environment impact analysis 5.1 Analysis of safeguard policies of World Bank 5.1.1 Screening of safeguard policies In this environment impact assessment, analyze the relationship between World Bank loan part and related projects of Zzhengzhou rail transit line 3 project and World Bank safeguard policies/procedures, and list the results in table 5.1-1.

Thus the World Bank Procedures Information Disclosure BP7.15 applies to this project. 5.2 Analysis of environment issues of similar projects in China 5.2.1 Main problems The main environment problems generated from urban rail transmit include: noise interference on residence area, school, hospital and office area at both sides of line from the operation of train and environment control equipment; impact of environment vibration on the building above and near the line due to traveling of train (especially for underground line) and secondary structure noise impact; impact on underground water level, water quality and ground building settlement during construction of underground line and stations; impact on water environment from domestic and production sewage from stations and car depots; disposal of hazard wastes such as battery of car depots; impact on traffic and resident livings by construction works during construction period, especially the open-cut station; impact on resident livings by relocation, demolition and resettlement during rail transit construction. 5.2.2 Lesson of experience (1) Noise nuisance issue After operation of urban rail transmit, especially the elevated line, it has large range and long time impact from noise radiation, and will lead to nuisance of surrounding residents if no effective insulation measures have been taken. According to the experience of subway line built, such as the overhead layout of Beiyuan to Tiantongyuan section of Beijing subway line 5, the complaint of surrounding 121      residents is increasing by time. Under these conditions, the operation company has to re-install noise barrier at both sides of line or other measures to reduce the subway noise pollution. The noise nuisance during rail transit construction period, especially individual subway project in some cities, which, to shorten the construction period, has the uncivilized construction phenomena such as night construction of large noise equipment, and it has been also complained by the residents. (2) Subway vibration issue Currently the environment vibration problem from subway vibration is mainly the vibration interference on the buildings above and near the line when subway train passes, which leads to vibration of buildings and therefore impact on the livings, study and rest of residents in the buildings. For example, although the vibration damper measures have been taken in Qingniao Jiayuan community near Beijing subway Daxing line (line 4), the residents in buildings can sense the vibration due to the vibration when train passes has exceeded the standard requirements, and the resident complaint has drawn high attentions by government departments and subway operation departments. (3) Impact on underground water and ground building settlement by subway construction When the subway is built in the city with low underground water level and abundant underground water resource, it may lead to falling of underground water level. At same time, the accidents of underground space such as collapse, explosion, improper or fault support will directly lead to settlement of ground. For example, the ground settlement accidents account for 25% of total accidents during construction period. The tunnel construction in subway section led to large range of ground settlement at crossing of Shennan Middle Road and Hongling Road with the settlement of more than 50cm; the cast iron water supply pipes along both sides of Shennan Middle Road and Hongling Road and therefore the water supply works are affected and damaged to certain extent due to ground settlement. (4) Wastewater discharge of station and car depot In the subway construction process of some domestic cities, the subway line is long and especially the car depots and stations at both ends of line are normally within municipal planning zones of which the sewage pipeline network has not fully provided. After subway servicing, the domestic and production sewage from stations and car depots can not discharge into municipal pipeline network and then relative sewage treatment plant for disposal, and will lead to pollution of surrounding waters. (5) Impact on traffic and resident living during subway construction period 122      The large scale and long period subway construction project will inevitably exert impact on the traffic and livings of local residents. Especially in urban center area, it will increase the traffic load and lead to continuous traffic congestion, and affect the traffic and livings of residents. During station construction of Zhengzhou subway line 1 and subway line 2, the traffic dispersion programs have been elaborately designed, and effectively relieved the congestion under strict implementation of traffic management departments and construction units and minimized the impact on traffic and resident livings. 5.2.3 Counter-measure of the project (1) Noise reduction measures To relieve the noise interference, this project adopts underground line layout throughout the line, even in Gaoxinqu district with the conditions for elevated line, so that it not only eliminates the impact of line on existing sensitive spots at both sides of line, but also is favorable for the implementation of planning at both sides of line. Aiming to the noise interference during construction period such as of open-cut stations, a series of measures have been requested for this project such as prohibiting large noise equipment construction at night time and surrounding noise barrier so as to minimize the noise impact on surrounding residents. (2) Vibration reduction measures The full line 3 is of underground line and passes under some buildings. To minimize the impact on buildings and residents, the strict vibration damping measures such as steel-spring floating-slab track bed have been taken in line 3 for the sensitive spots passing beneath and nearby environment wit h over-limit vibration so as to minimize the impact on surrounding environment after train servicing. (3) Measures for mitigation of Geological risk and underground water impact Considered the features of collapse and settlement risks during subway construction, and various geological conditions and construction conditions at different sections along line 3 project, determine different construction methods, mainly of shield method for underground section construction which has the least impact on underground water and ground settlement. During station construction, the underground diaphragm wall retaining structures are adopted for the foundation pits of stations in Huijiqu with existing narrow road and near the surrounding buildings, so as to effective prevent leakage and reduce the fall of underground water level and ground settlement surrounding the stations. (4) Sewage treatment measures The Jialu River parking depot and Xinliu Road Station of 3 line are in the range of 123      Matougang sewage treatment plant phase II project, and there is no municipal pipeline network. It is predicted that the expansion construction of Matougang sewage treatment plant can be completed before operation of subway (the capacity after expansion will be 50×104m3/d, and it is in Huiji District old city (Shamen Road Station (inclusive) - Jinshui Road Station (inclusive)). The existing municipal sewage pipeline network and current Matougang sewage treatment plant (30×104m3/d) will treat the sewage collected. The section from Jinshui Road Station (exclusive) to Zhongxing Road Station (exclusive) has municipal sewage pipeline network and it is possible to connect the Wangxinzhuang sewage treatment plant (current 40×104m3/d and 60×104m3/d after expansion) via existing municipal pipeline for treatment; the section from Zhongxing Road Station (exclusive) to Hanghai East Road (inclusive) has part of municipal sewage pipeline network and is within the service range of Chensanqiao sewage treatment plant, so it can connect to Chensanqiao sewage treatment plant (in construction, 20×104m3/d) via existing main pipe or newly-built temporary pipeline for treatment; The Hanghai East Road car depot has no supporting municipal pipelines at present and it is within in the service range of Gengzhuagn sewage treatment plan in planning, so the sewage in this area can be discharged into Chensanqiao sewage treatment plant through Gengzhuang sewage treatment plant (7×104m3/d) or newly built temporary pipeline. The sewage treatment capacity of above sewage treatment plants can meet the requirements for Zhengzhou 3 line The municipal sewage pipeline network near the section from Shamen Road Station to Zhongxing Road Station of 3 line has the supporting conditions, and the sewage pipeline network of others such as Xinliu Road Station, Boxue Road Station, Hanghai East Road Station, Parking depot and car depot is to be completed. During construction of 3 line, it is necessary to track the synchrony of construction of sewage pipeline network near Jialu River parking depot area and Hanghai East Road car depot with the subway project. (5) Traffic dispersion measures Based on the experience from 1# Line, the detailed traffic dispersion programs are prepared for the stations along the line, especially the stations in old city and the open-cut stations with large traffic flow so as to mitigate the traffic congestion, and the proper construction programs are planned to reduce the impact on resident livings. 124      5.3 Sound environment influence assessment and sound measures of environment protection 5.3.1 Analysis of noise source 5.3.1.1 Noise source analysis during construction period The construction sites of this project are classified as: underground station, section, car depot, integrated base and etc. The noises during construction period mainly come from open-cut construction of underground station (including civil construction of station entrance/exit and air shaft), civil construction of car depot and integrated base; it is mainly from the operation noises of various construction machines, such as road breaker, excavator, bulldozer, air compressor and etc, and also the noises of various construction transport vehicles and noises of building demolition and breaking works of existing road. The shield method construction of sections, installation of mechanical and electrical equipment in full line and the decoration works have less impact on ground surface noise sensitive objectives. The main construction machines used in all construction phases with open-cut and covered cut method for underground stations include hydraulic grooving machine, 50t and 100t crane, caterpillar excavator, loader, concrete pump truck, bulldozer, grader machine, air compressor and vibrator. The main construction machinery used in integrated base construction sites includes bulldozer, loader, dump truck, crane, concrete pump truck, air compressor and v vibrating bar. According to analog survey and monitoring, the noise levels of various construction machinery and vehicles at different construction stages are shown in table 5.3-1.                 125      Table 5.3-1 Noise levels of construction machinery and vehicles Distance from measurement Construction Lmax No. Construction machine point to construction machine phase (dBA) (m) Wheeled hydraulic 1 5 84 excavator 2 Bulldozer 5 84 Civil construction 3 Wheeled loader 5 90 phase 4 Various drill rigs 5 87 5 Truck 5 92 6 Various pile driver 10 93 – 112 Foundation 7 Grader machine 5 90 construction phase 8 Air compressor 5 92 9 air hammer 5 98 10 vibrating machine 5 84 11 concrete pump 5 85 Structure 12 air wrench 5 95 construction phase 13 mobile crane 5 96 Various rolling 14 5 76 – 86 machine 15 paving machine 5 87 Each phase 16 generator 5 98 As shown in table 5.3-1, the noise levels of construction machinery and vehicles are relatively high. In actual construction process, it is normal that several machines operate at same time, so the noises from various noise sources superpose with more impact. 5.3.1.2 Noise source intensity during operation period Zhengzhou rail transit 3 line phase I project is of underground line and it is configured with 1 parking depot and 1 car depot. According to the characteristics of noise source impact, the noise sources impacting external environment in underground section mainly include ventilation pavilion noise, cooling tower and main substation noise; the train running noise will occur at the access section of car depot and the fixed sound source devices in workshop also generate certain noise effect.

Therefore, the prediction results of the air-conditioning period should be higher than those of the non-air conditioning period. The vast majority of sections in this project advances under existing urban road and the ventilation pavilion area is not far from the road, so most of assessment points are interfered by road traffic noises and it is general for background noise overlimit. The traffic noise will be still the main cause after project is built and put into service. ○. Population affected by noise d The population in sensitive spots along the line which is directly affected by subway pavilion and cooling tower noise is about 10,101. c. Analysis of impact range According to noise source intensity of ventilation pavilion and cooling tower, the protection distances of sound sources are summarized in table 5.3-14 (not considering ambient noise current value and open without blocking). Table 5.3-14 Noise protection distance of ventilation pavilion and cooling tower Standard-reaching distance (m) Noise source GB3096-2008 GB3096-2008 GB3096-2008 Description Category 4a Category 2 Category 1 category Day Night Day Night Day Night time time time time time time Two pitons + Set 2m long-plate type silencer ≥3 ≥20 ≥10 ≥38 ≥18 ≥71 exhaust pavilion +new ventilation Set3m long-plate type silencer * ≥6 ≥3 ≥11 ≥6 ≥20 pavilion Normal cooling tower ≥7 ≥42 ≥23 ≥80 ≥42 ≥154 cooling tower Low noise cooling tower ≥4 ≥13 ≥7 ≥24 ≥13 ≥45 Set 2m long-plate type silencer ≥7 ≥48 ≥25 ≥90 ≥48 ≥170 in ventilation pavilion Ventilation Set 2m long-plate type silencer pavilion (piston in ventilation pavilion; adopt ≥4 ≥24 ≥12 ≥45 ≥24 ≥85 + exhaust + new) low noise cooling tower + Set 3m long-plate type silencer cooling tower in ventilation pavilion; adopt ≥4 ≥14 ≥8 ≥26 ≥14 ≥50 low noise cooling tower Two piston Set 2m long-plate type silencer * ≥9 ≥3 ≥17 ≥6 ≥32 ventilation pavilions Set 3m long-plate type silencer * ≥3 * ≥6 * ≥9 Note: “*” indicates it can meet the standard outside of ventilation pavilion shutter; night time standard-reaching distance refers to the standard-reaching distance in 151      actual operation period. As shown in table 5.3-14, in the noise of ventilation pavilion and cooling tower, the noise from cooling tower plays the predominant position, so the noise standard-reaching protection distances in zone categories 4a, 2 and 1 around the ventilation pavilion during non-air conditioning period (cooling tower not activated) are separately of 20m, 38m and 71m; during air conditioning period, if conventional cooling towers are used, the noise protection distances for zone categories 4a, 2 and 1 around the ventilation pavilion are separately of 48m, 90m and 170m; if the low noise cooling tower is used, the noise protection distances for zone categories 4a, 2 and 1 around the ventilation pavilion are separately of 24m, 45m and 85m. From this view, to reduce the project demolition and save the urban land resource, the application of low noise environment control device or “combination of prevention and management” purposeful noise control program can effectively control the noise impact in underground station ventilation pavilion area. B. Noise prediction and assessment in area of car depot and integrated base Parking depot is located at north of Lian-Huo highway and south of Jialu River, and there is no noise sensitive spot around it. The car depot is located at east of Chaohe River and south to Jingnansan Road, and there is makeshift houses sporadically distributed around the traction line. The fixed sound source devices are set in workshop or factory with the feature of quick attenuation, so it has less impact on external environment in the car depot. The main interference from the noise of the car depot and parking lot on the external environment is from the parking lot’s inlet and outlet segments and test line, and from the parking lot’s vehicle operating noise. For the factory boundary noise prediction of the parking lot and car depot is shown in Table 5.3-15 and Table 5.3-16.

Hanghai East Road car depot is located in the development zone as category 2 area; the car depot is mainly affected by the vehicle operation noises of testing line and release line during operation period. As shown in table 5.3-16, the noise at boundary of car depot is 49.6-71.1 dB(A) at daytime and 36.3-50.0dB(A) at nighttime; in contrast to the category 2 standard in GB12348-2008 Emission Standard for Industrial Enterprises Noise at Boundary, the noise at east boundary at daytime exceeds the standard value for 11.1dBA due to close to the testing line and all other boundaries meet the standard requirements. C. Noise impact prediction and assessment of main substation This project newly builds one 110kV main substations of BoXue road Station main substation, which is of indoor ground layout. There is no sensitive spot around BoXue road Station main substation; which is affected by road noises and social noises with the day time level of 60.5dBA and 54.2dBA at night time. The noise level simply affected by the main substation is 33.6dBA. The environment noise prediction value maintains the present status without any increment. 153      5.3.3 Noise pollution control measures 5.3.3.1 General According to the basic principles of environment protection “Mainly of prevention, combination of prevention and control, comprehensive management” in domestic and basic strategic policy of “Integration of social benefit, economic benefit and environment benefit”, and the guiding concept of “Eliminate the root cause for pollution control”, the noise pollution prevention measures of this project shall comply with following sequences: (1) Firstly carry out noise control on sound sources and select the device and structure types with low noise. (2) Secondly strengthen the design of noise pollution abatement works, mainly from blocking of noise propagation path and sound receiving points. (3) Finally, based on “Prevention First” principle and in combination with urban modification and planning, reasonably plan the land functions along the line and optimize the building layout to avoid new environment problems. 5.3.3.2 Suggestions for noise pollution control during construction period According to the regulations in Law of the People's Republic of China on Prevention and Control of Pollution from Environmental Noise articles 27, 28, 29 and 30, the project shall comply with national ambient noise emission standards at building construction boundary; the construction unit shall report, 15 days before commencement of construction, to the competent administrative department for environmental protection of the local people's government at district level the name of the project, the construction site, the length of time needed for completion of the project, the possible level of environmental noise and the measures taken for prevention and control of such pollution. In an urban area where noise-sensitive structures are concentrated, construction operation that produces environmental noise pollution is forbidden at night. For continued operation due to special needs, there must be a permit issued by the people's government at or above the district level or by the relevant competent department, and the approved night time operations be made known to the residents in the neighborhood. Furthermore, put forth following measures and suggestions for noise environment impact during construction period in combination with actual conditions of this project: (1) During construction period, it must accept the supervision and inspection of environment protection department and take effective vibration damping and noise reduction measures according to the regulations in Noise Limits for Construction site (GB12523-90) without disturbing the residents. The Night Construction Permit shall be obtained for night construction. (2) The machines with large noise such as generator and air compressor shall be laid out at remote place or in tunnel, and kept from sound environment sensitive spots 154      such as residential area, schools and hospitals; they shall be regularly maintained and strictly comply with the operation specifications. The mobile diesel generator car must not be used as possible, instead the low noise generator car with noise control measures must be used or reliable ventilation and sound insulation measures must used for both diesel generator or air compressor. (3) The static pile driver shall be used in sensitive section rather than cast-in-place pile. The low noise processes such as “reverse construction method” and “covered excavation method in amplitudes” shall be used as possible instead of open cut construction method. It is forbidden to drive the pile. If necessary, it shall be reported to Zhengzhou Environment Protection Bureau for approval and limit the operation time period in the range of 7:00 - 12:00 and 14:00 - 22:00; the application of other construction machinery and devices with high noise shall be also limited in the time range of 7:00 - 12:00 and 14:00 - 22:00. If necessary for continuous construction, it must obtain the advance approval from Zhengzhou Environment Protection Bureau. Arrange the low noise construction works such as shielding and hoisting at night time. (4) The access of transport vehicles to construction site shall be arranged at the side far from the residential area. (5) Adopt commercial concrete rather than the operation method to set the concrete mixer in construction site. (6) Optimize the construction program, reasonably arrange the construction time limit and minimize the noise hazard of building construction environment. During tendering and bidding of construction project, list the measures to reduce the environment noise pollution in the contents of construction organization design, and specify them in the contract signed. (7) According to Notice on Strengthening the Ambient Noise Pollution Supervision and Management during College Entrance Examination issued by State Environmental Protection Administration of China in April 26th in 1998, during college entrance examination and half an month before the period, prohibit any building construction works which may lead to noise over-limit and resident disturbance besides strict control for various environment noise sources acceding to related national environment noise standards. (8) During construction period, the employer, construction unit, design unit and street office establish the special leading group. Set 24h on-duty hotline and special liaison man and strengthen the communication with the residents along the line, and timely improve the management measures according to resident advices so as to ensure the living quality of the residents along the line. (9) For the machines and tools with high noise, increase the height of temporary noise barrier if necessary. For the sensitive spots with heavy noise impact by station construction (see table 5.3-6), recommend setting temporary 3-4m high sound insulation fencing or noise barrier or directly set up the sound insulation work shed (or sound insulation flexible curtain) with effective design; it can also consider to establish temporary workshop near the sensitive spots to function as insulation wall so as to relieve the noise impact. The estimated cost for noise prevention and control and noise compensation during construction period is 2.25 million Yuan. 155      （See table 5.3-17） Table 5.3-17 List of measures to be taken on noise-sensitive points during construction Sensitive point Closest distance from Predicted noise Investment No Position relative Predicted noise after Station Size the constructional before measures Measures to reduce noise (RMB . to stations measures (dB(A)) boundary (m) (dB(A)) ¥:×104) Chengshi 5 units - 2 households, 6 Bei’an North end 1 floors, 1 building, about 60 18  54.4  47.4  Community west side households  1# building 5 units, 12 households Changxing South end 2 each unit, about 60 13  57.3  50.3  Building west side households Huiji District Erect a 3m-high fence;

So the proper selection of fan and cooling tower is critical to prevent the ambient noise impact in underground section. In view that the environment control device model in the design of this project has not finally determined, the assessment puts forth following requirements for the model selection: (1) Fan model selection and design requirements Under the premise of meeting the project ventilation requirements, adopt the fans with low noise and excellent acoustic performance as possible and note following problems in ventilation pavilion design: A. During location selection of ventilation pavilion, the noise prevention distance specified in table 5.3-14 shall be kept far from the noise sensitive spots as possible with air outlet opposite to sensitive spots. B. Make full use of barrier functions of non-sensitive building s such as station devices, entrance/exit and management rooms, and set them between the ventilation pavilion and sensitive buildings. C. Reasonably control the exhaust speed of ventilation pavilion and reduce the air flow noise. (2) Model selection of cooling towers The cooling towers are normally arranged on ground, top of ventilation pavilion or underground low buried depth position, and their radiation noises directly impact the external environment. To block the noise propagation path, it is necessary to fully enclose them. The required enclosed barriers not only feature large volume and also impact the ventilation of cooling tower. So the optimal route is to use low noise cooling tower or ultra-low noise cooling tower and strictly control the noise value of sound source. There are many manufacturers and models of low noise cooling towers and the production technical levels tend to be mature. For example, the acoustic test data of low noise type (DBNL3) and ultra-low noise type (CDBNL3) cooling towers are shown in table 5.3-18. Table 5.3-18 Noise values of low noise type and ultra-low noise type cooling towers Low noise type (DBNL3) Ultra-low noise type (CDBNL3) Model Distance (m) Noise value (dBA) Distance (m) Noise value (dBA) 3.732 58.5 4.6 54.0 150 10 52.0 10 47.5 163      3.732 59.5 4.6 55.0 175 10 53.0 10 48.5 4.342 60.0 5.7 55.0 200 10 54.0 10 49.6 4.342 61.0 5.7 56.0 250 10 55.6 10 50.6 5.134 61.0 6.4 56.0 300 10 56.8 10 51.8 5.134 61.5 6.4 56.5 350 10 57.3 10 52.3 As shown by the noise values f various cooling tower models in table 5.3-17, the noise values of low noise type cooling tower is over 10dBA lower than those of normal cooling towers, and the noise reduction of ultra-low noise cooling tower to normal cooling towers is more than 15dBA. The assessment recommends the employer and design department strictly control the quality when adopting ultra-low noise cooling tower and the noise indexes must reach or excel the noise indexes specified in GB7190.1-1997. The noise indexes of various cooling towers specified by GB7190.1-1997 are shown in table 5.3-19. Table 5.3-19 Noise indexes of various cooling towers specified in GB7190.1-1997 Nominal cooling Noise index flow rate m3/h P type D type C type G type 30 68.0 60.0 55.0 70.0 50 68.0 60.0 55.0 70.0 75 68.0 62.0 57.0 70.0 100 69.0 63.0 58.0 75.0 150 70.0 63.0 58.0 75.0 200 71.0 65.0 60.0 75.0 300 72.0 66.0 61.0 75.0 400 72.0 66.0 62.0 75.0 (II) Urban planning and reasonable layout of buildings For reasonably planning of land use along the line, according to related regulations in Subway Design Specifications and in combination with the noise prediction results of this project, it is recommend that no noise sensitive building such as residential area, school and hospital may be planned to construct in the noise prevention distance range of 15m (category 4 zone), 26m (category 2 zone) and 50m (category 1 zone) from the station ventilation pavilion and cooling tower; if necessary to construct noise sensitive building in related sound environment function area, the developer must 164      consider the isolation function of building itself, and ensure the internal sound environment of building meets the application functions. Scientifically plan the layout of buildings to arrange the first row buildings near the noise sources as noise non-sensitive building such as commercial and office building. In combination with the modification of old town, firstly demolish the residential houses near the sound source, and, in combination with the greening design and re-arrangement of buildings, reserve the sound prevention distance for newly developed buildings or make use of the sound blocking and insulation effects of non-sensitive buildings so as to ensure the impact on sensitive buildings within allowable range of standard. (III) Operation management of rail transit To strengthen the operation management, it can effectively abate the noise impact on external environment by train running mainly with following measures: (1) Periodically trim the wheel tread The wheel tread may present rough surface of different extents after operation of certain period. When there is a series of rough spots with the length of more than 18mm on wheel, it must be trimmed. The test demonstrates that the wheel after ground can reduce the squeak by 2-5dBA and roaring by 2-6dBA. (2) Keep steel rail surface smooth Since the smoothness of steel rail surface directly influences the noise volume of wheel and track, so it is necessary to grind the ripple and rough surface on steel rails with grinder after operation of certain time after operation of certain time. It can reduce the wheel and track noise for 5 – 6 dBA after taken such measure. (3) Operation management of car depot and integrated base Improve the operation management of integrated base, enhance the environment protection awareness of driver and conductor and control the whistling; prohibit test run operation at night time and production in workshop with high noise. 5.3.3.4 Noise control engineering in sensitive spots (I) Noise control for environment control device in underground section (1) Demolish the sensitive buildings (1) Adjust the position of ventilation pavilion and cooling tower According to requirements of subway design specification, adjust the ventilation pavilion and cooling tower positions so as to ensure the distance from sensitive spots is more than 15m. If some areas can not be moved to beyond 15m, then the wind pavilion and cooling tower shall be relocated to one side of the road center to be away from sensitive points at both sides of the road. (2) Block the propagation path of sound source For the ground noise sources such as cooling tower, the measures such as setting noise 165      barrier or applying sound absorption materials on inside surface can be taken to effectively block the noise propagation path and achieve certain sound insulation and noise reduction effect. (3) Protection measures of sound receiving point The sound insulation with building method can be used for protection of sound receiving point; for example, the sound insulation ventilating window can reduce the indoor noise for about 20dBA to enable the indoor noise to meet the application requirements of functions. The sound insulation ventilating window has the advantages of less investment, but affecting the view and ventilation and certain affect on daily lives of residents, so this assessment can be used as an auxiliary measure. (4) Sound damping design For exhaust and inlet pavilions, the silencers can be installed on air ducts and before and after the fan to reduce the noise impact by pavilion, the plate type silencer can be installed in air duct and the integrated silencer can be installed in air pipe. The analog survey and test results show that the silencer can reduce the noise for about 10dBA every meter. In addition, the measures such as maximizing the surface area of air duct, affixing sound absorption materials, mounting damping shutter at outlet, optimizing geometric section of silencing shutter and reducing the air noise can effectively reduce the pavilion noise impact to certain extent. It is recommended to use environment friendly, fungi-proofing and mould proof materials to improve the air and hygienic conditions inside and outside the stations. (II) Protection measurement and effect analysis of noises in underground section sensitive spots This environment impact assessment, from the view of least favorable conditions, adopts noise prevention measures in reference to environment noise prediction value during air conditioning period and enables the environment noise at sensitive spots to achieve related environment standard, and maintains present level of ambient noise for sensitive spots in which the present ambient noise level has exceeded the limits.

For 17 ventilation pavilions including Xinliu Road Station west side ventilation pavilion, Shamen Road Station north ventilation pavilion, Xinglongpu Road Station south ventilation pavilion, Dongfeng Road Station north ventilation pavilion, Dongfeng Road Station south ventilation pavilion, Nongye Road Station northwest ventilation pavilion, Nongye Road Station southwest ventilation pavilion, Huanghe Road Station north ventilation pavilion, Huanghe Road Station southwest ventilation pavilion, Jinshui Road Station northeast ventilation pavilion, Jinshui Road Station southeast ventilation pavilion, Jinshui Road Station southwest ventilation pavilion, Taikang Road Station south ventilation pavilion, Erqi Square Station northwest ventilation pavilion, Shuncheng Street Station northeast ventilation pavilion, Chengdong Road Station northwest ventilation pavilion, recommend taking the noise reduction measures with silencing treatment and make the exhaust port of ventilation pavilion back to the sensitive buildings. Recommend using the ultralow noise cross flow type cooling tower at three locations including Shamen Road Station north side, Dongfeng Road Station south side, Nongye Road Station southwest side, Huanghe Road Station north side and Taikang Road Station south side, and the low noise cooling tower at 4 locations including Xinglongpu Road Station south side, Jinshui Road Station east side, Dongdajie Station southeast side and Chengdong Road Station northeast side. The total environment protection investment required for noise control of underground station environment control devices is 4.85 million yuan (excluding removal expense and modification and design cost), in which includes the newly added 1.5 million yuan for ultralow noise cross flow cooling tower, new added 0.8 million yuan for low noise cooling tower and 2.55 million yuan for addition of silencer in ventilation pavilions. (III) Noise control measures for car depot and integrated base The noise control measures for car depot boundary are shown in table 5.3-21 and table 5.3-22. 174      Table 5.3-21 Schedule for noise control measures at boundary of Jialu River parking depot Boundary noise over-limit amount Estimated Predicted (dBA) Suggestion for Control effect investment boundary Actual control measure analysis (10,000 position operation program Daytime yuan) at nighttime Noise reduction by Heighten the the fencing wall for fencing wall to 1m out of west about 3dB; about 3.5m; set the green boundary 3dB by green belt; / 0.7 belt of no less than 9.6 (about 6m from the boundary noise 10m wide and U-channel) level meets the about 240 linear standard meters long requirement Table 5.3-22 Schedule for noise control measures at boundary of Hanghai East Road car depot Boundary noise Estimate over-limit d amount (dBA) investme Predicted boundary Suggestion for control Control effect Actual position measure program analysis nt operati Day (10,000 on at time nightti yuan) me Noise reduction by the fencing wall 1m out of east Set 2m high sound for about 3dB; boundary (7m from barrier beside testing 10dB by sound testing line and 52m 11.1 / line; normal fencing barrier; the 135 from train checkup wall of 1800 linear boundary noise shed) meter level meets the standard requirement 5.3.4 Assessment summary 5.3.4.1 Assessment summary during construction period For the ambient sensitive spots near the subway station affected by construction noise, after taken the noise control measures during construction period provided in this environment impact assessment, the environment impact of construction noise has been relieved to certain extent, but it still can not meet the requirements of standard GB12523-90 Noise Limits for Construction Site; for the residents affected by construction noise, recommend the employer and construction unit to negotiate the compensation issues. 175      5.3.4.2 Assessment summary during operation period (I) Noise of underground station environment control system (1) Prediction results The 44 sensitive points within the evaluation scope of the underground stations along the line will be purely affected by subway-related environmental control equipment noise (without superimposed background). The equivalent continuous A sound level during day’s and night’s actual operational period will respectively be 35.3～71.5dB （A）and 36.2～71.5 dB（A）. Among the daytime 44 measuring points, 18 has sensitive standard-exceeding, with the standard-exceeding amount being 2.4～12.5dB (A), The prediction points’ standard-exceeding rate is 40.9%; among nighttime actual operating hours’ 43 acoustic sensitive points, in addition to the sensitive points of standard exceeding at daytime still exceeding the standards, there are 28 sensitive points of standard exceeding, with the standard exceeding amount being 1.1 ～ 16.6dBA. The prediction points’ standard-exceeding rate is 65.1%. During the air-conditioning period, each sensitive point is purely affected by subway-related environmental control equipment noise (without superimposing background). The daytime’s and nighttime’s actual operational period’s equivalent continuous A sound levels respectively are35.3～71.5dB（A）and 36.2～71.5dBA.dB (A).Among the daytime 44 sound sensitive points’ measuring points, 25 sensitive points are standard-exceeding, with a standard-exceeding amount being 2.1 ～ 12.5dBA, and with the prediction points’ standard exceeding rate being 56.8 percent. For the actual operating hours at night, 30 sensitive points are standard-exceeding, with a standard-exceeding amount being about, 0.4～16.6dBA, and the prediction points’ standard-exceeding rate being 69.8 percent. (2) Scope of Influence Among the wind pavilion and cooling tower noise, the cooling tower noise is dominant. Therefore, the non-air-conditioning period (not turning on the cooling tower), around the wind pavilion area, Classes 4, 3, 2 and 1 areas’ noise standard-reaching distances are 17m, 17m, 30m and 54m respectively, with a relatively small range; if the air conditioning period uses conventional cooling towers, the noise protection distances around the wind pavilion’s Classes 4, 3, 2 and 1 areas are respectively 29m, 29m, 52m and 92m, with a larger context; if low-noise cooling towers are used, the noise protection distances of Classes 4, 3, 2 and 1 areas around the wind pavilion area are respectively 19m, 19m, 34m and 59m, with the protective distance being greatly reduced compared with ordinary cooling towers. Thus, in order to increase the supply of land resources along the line, low-noise environmental control equipment will be used or the "combination of prevention and cure" will be put forward for specific noise control solutions, which can effectively control the underground stations’ air pavilion areas’ noise impact. (3) Number of people to be affected For the sensitive points along the line, the number of households directly affected by subway-related wind pavilion and cooling tower noise is about 2886, with a total of 176      approximately 10,101 people. (II) Noise at boundaries of car depot and parking depot (1) The Jialu River parking depot and Hanghai East Road car depot are in suburb area without the sound environment sensitive spots such as village, school and hospital. (2) The noise at boundaries of Hanghai East Road car depot is 49.6-71.1 dB(A) at daytime and 36.3-50.0dB(A) at night operation period. In contrast to standard for category 2 in GB12348-2008 Emission Standard for Industrial Enterprises Noise at Boundary, the east boundary noise exceeds the standard value by 11.1dBA due to noise from testing line, and all other boundaries meet the standard at different prediction years. (3) The noises at boundary of Jialu River parking depot is 48.7-57.5 dB(A) at daytime and 33.4-50.7dB(A) at night operation period. In contrast to standard for category 2 in GB12348-2008 Emission Standard for Industrial Enterprises Noise at Boundary, except east boundary, all other boundaries exceed the standard values with the maximum over-limit amount of 0.7 dB(A). (III) Main substation noise There is no sound environment sensitive spot around Boxue Road Station main substation at present. The contribution of main substation noise is 33.6dBA; the environment noise prediction value maintains the status quo without increment. 5.3.4.3 Program for noise pollution control measures (I) Proper selection of device and type (1) Under the premise of meeting the project ventilation requirements, adopt the fans with low noise and excellent acoustic performance as possible. (2) Select low noise and ultra-low noise type cooling tower. (3)The wind pavilions and cooling towers should have rational layout, 15m or more from a sensitive point, with the air outlet facing away from the sensitive buildings. (II) Urban planning and reasonable layout of buildings For new development area, according to related regulations in Subway Design Specifications and in combination with the noise prediction results of this project, it is recommend that no noise sensitive building such as residential area, school and hospital may be planned to construct in the noise prevention distance range of 15m (category 4 zone), 26m (category 2 zone) and 50m (category 1 zone) from the station ventilation pavilion and cooling tower; otherwise it shall enhance the building sound insulation requirements according to Law of Noise to ensure the internal sound environment of building meets the application functions. Scientifically plan the layout of buildings to arrange the first row buildings near the noise sources as noise non-sensitive building such as commercial and office building. 177      The Jialu River parking depot is out of the central urban area planning zone and of category 1 sound functional area. At present, except the east boundary, the noises of all other boundaries exceed the standard value. There is sensitive spot around at present, and recommend not building the sensitive buildings such as residential area, school and hospital within 100m range in future construction. (3) Pollution control of noise sensitive spot Noise control measures at underground sections ●For 7 ventilation pavilions and 5 cooling towers including Shamen Road Station south cooling tower and ventilation pavilion, Dongfeng Road Station north ventilation pavilion and cooling tower, Dongfeng Road Station south ventilation pavilion and cooling tower,Nongye Road Station southwest ventilation pavilion and cooling tower, Huanghe Road Station north ventilation pavilion and cooling tower,Taikang road station southwest ventilation pavilion and cooling tower,,Jinshui Road Station northeast ventilation pavilion and cooling tower, Erqi Square Station northwest ventilation pavilion, East Street Station southeast cooling tower, which do not comply with the environment protection control distance requirements in Code for Metro Design, their locations shall be adjusted to control the distance more than 15m far away. ●For 17 ventilation pavilions including Xinliu Road Station west side ventilation pavilion, Shamen Road Station north ventilation pavilion, Xinglongpu Road Station south ventilation pavilion, Dongfeng Road Station north ventilation pavilion, Dongfeng Road Station south ventilation pavilion, Nongye Road Station northwest ventilation pavilion, Nongye Road Station southwest ventilation pavilion, Huanghe Road Station north ventilation pavilion, Huanghe Road Station southwest ventilation pavilion, Jinshui Road Station northeast ventilation pavilion, Jinshui Road Station southeast ventilation pavilion, Jinshui Road Station southwest ventilation pavilion, Taikang Road Station south ventilation pavilion, Erqi Square Station northwest ventilation pavilion, Shuncheng Street Station northeast ventilation pavilion, Chengdong Road Station northwest ventilation pavilion, recommend taking the noise reduction measures with silencing treatment and make the exhaust port of ventilation pavilion back to the sensitive buildings. ●Recommend using the ultralow noise cross flow type cooling tower at three locations including Shamen Road Station north side, Dongfeng Road Station south side, Nongye Road Station southwest side, Huanghe Road Station north side and Taikang Road Station south side, and the low noise cooling tower at 4 locations including Xinglongpu Road Station south side, Jinshui Road Station east side, Dongdajie Station southeast side and Chengdong Road Station northeast side. The total environment protection investment required for noise control of underground station environment control devices is 4.85 million yuan (excluding removal expense and modification and design cost), in which includes the newly added 1.5 million yuan for ultralow noise cross flow cooling tower, new added 0.8 million yuan for low noise cooling tower and 2.55 million yuan for addition of silencer in ventilation pavilions. 178      Noise control measures for car depot and integrated base ● Prohibit test run operation and high noise workshop production works at night time. ● Set 10m wide green belt and fencing wall around Jialu River parking depot, in which the west fencing wall is heightened to 3.5m and it needs additional 609,000 yuan investment. ● A 2m high sound barrier is set at a testing line of Hanghai East Road car depot and it needs additional 1.35 million yuan investment. Above total noise control expense is about 6.809 million yuan (excluding removal expense). 179      5.4 Ambient vibration impact predication and protection measures 5.4.1 Vibration sources 5.4.1.1 Vibration sources during construction period The vibration sources during construction period in this project are mainly of vibration from power type construction devices.

(1) Underground section According to Handbook of Vibration and Noise Control of Urban Rail Transit, the 180      subway vibration source intensities of main cities in domestic are summarized in table 5.4-2.

(2) Ground section According to actual measurement data from Jingjiang Park station to Lianhua Road station of Shanghai Metro line 1, the subway vibration source intensities at ground section are summarized in table 5.4-3.

Among the stations, JinShui east road station adopts covered excavation method and other stations adopt open cut method. As shown by the practices of these construction methods, the vibration impact on external environment can be controlled if strictly controlled and constructed according to specifications. However, since the construction section in urban area is in dense environment sensitive area, the vibration generated from operation of mechanical devices, vehicles and tunnel blasting construction may impact the ambient environment, so it is necessary to analyze the environment impact from construction machines and explosion vibration during construction period. (I) Environment impact assessment of construction machinery vibration (1) Source intensity of vibration pollution from construction pollution According to construction features of this subway project, the mechanical devices and vibration source intensities used during engineering construction are shown in table 5.4 -5. Table 5.4 -5 Reference vibration levels of vibration source intensity of construction machines (VLzmax: dB) Distance of measurement point from construction device Constructio Construction (m) n phase devices 5 10 20 30 40 excavator 82-84 78-80 74-76 69-71 67-69 civil constructio bulldozer 83 79 74 69 67 n phase rolling machine 86 82 77 71 69 182      heavy transport 80-82 74-76 69-71 64-66 62-64 vehicle shield machine / 80 - 85 / / / pile driver 104-106 98-99 88-92 83-88 81-86 Foundation Vibrating hammer 100 93 86 83 81 constructio n phase air hammer 88-92 83-85 78 73-75 71-73 Air compressor 84-85 81 74-78 70-76 68-74 Structure Drilling machine 63 constructio n phase concrete mixer 80-82 74-76 69-71 64-66 62-64 (II) Vibration environment impact analysis of construction machines The construction machinery of this project is mainly of vibration type operation, including the vibrations from shield machine, construction works such as pile driving and excavation, and transport and handling of transport vehicles, so the construction works inevitably impact the along-line traffic, buildings and residents livings. As shown in table 5.4 -5, except pile driving works, the vibration level at location 10m from normal construction machinery is 74-85dB, 64-76dB at 30m location and 62-74 dB at 40m, so only the locations with more than 30m distance can meet the requirements of day time 75dB for “mixed zone, CBD”, “industrial concentration area” and “both sides of traffic arterial line”, and the locations more than 40m away can meet the requirements of day time 70dB for residential and culture education area. As shown by the field survey, the locations affected by construction machinery vibration are mainly of environment sensitive spots near the station (see table 5.4-6). Most of the construction sites of this project are located in urban built-up area and near the resident housing, so part of sensitive spots is hard to meet the limit requirements of GB10070-88 Standard of Vibration in Urban Area Environment and the construction machinery vibration inevitably impacts the sensitive spots around construction sites. The section tunnel adopts shield method construction with less vibration effect on ground surface at both sides of line and certain impact on vibration right above the line, which is mainly of ground settlement. 183      Table 5.4 -6 Summary list of main sensitive spots of station contruction vibration impact The Burie Buildin Sensitive Target recent d Using gs Contructi constructi SN station Mileage section distance depth function Scale point Name Categor on year on way overview （m） （m） y Yuhua ninth 25 Xinliu K0+100 about city, Xinliu Road-Shamen floors， Open cut 1 road ～ 46 14.5 House I 1475 2010 Building 1 Road Station Section Frame methed station K0+280 househlds #~ 3 #

The main job contents include: On basis of field survey and monitoring, carry out monitoring assessment of ambient vibration status of the project before built-up. The ambient vibration present status monitoring covers all sensitive spots in assessment range, and all present status values of sensitive spots are of actual measurement; Adapt analog measurement method to determine the vibration source intensity, carry out vibration analog monitoring for the vibration sensitive buildings in 10m range from vertical above of tunnel to both sides of outer line centerline and critical historic and culture buildings to be protected, and predict the vibration impact of secondary structures; The vibration environment impact prediction covers all sensitive spots and provides the vibration prediction amount, variation from present status and over-limit amount of each sensitive spot during operation period; Aiming at the environment vibration impact range and extent on environment protection objectives, put forth the vibration protection measures, carry out technical and economic feasibility demonstration and provide the vibration reduction effect and investment estimate; Provide reference from decision making by environment management and urban planning department. This assessment provides the vibration standard-reaching protection distance of buildings along line in table form. (II) Vibration analog investigation and analysis When the subway train runs on track, it generates knocking vibration, sliding vibration and rolling vibration due to interaction between wheels and rails, and they are transferred to tunnel lining via sleepers and ballast bed and then to the ground, and therefore lead to the vibration of ground buildings and impact on ambient environment. (1) Underground section According to Handbook of Vibration and Noise Control of Urban Rail Transit, the subway vibration source intensities of main cities in domestic are summarized in table 5.4-7. Table 5.4 -7 Vibration source intensity of subway operation of main cities in domestic (VLzmax, dB) Vehicle Distance of Vehicle Train Train Vibration Vehicle dead measurement Line name length Model marshalling speed level manufacturer weight point from (m/car) (car) (km/h) VLzmax(dB) (t/car) track (m) Guangzhou subway German 24.4 37 A 6 60 0.5 87.0 No.1 line Tianjin Changchun 19.0 37 B 4 60 0.5 87.0 Subway Shanghai German 23.5 38 A 6 60 0.5 87.4 Metro line 193      1 Beijing Changchun, subway 19.0 37 B 6 60 0.5 87.2 Beijing No.1 line As shown in table above, in case of following line conditions: travel speed of 60km/h, elastic split type fastener, normal integrated ballast bed and 60kg/m seamless steel rail, the vibration source intensity VLzmax generated when rail transit A type train passes the track can be taken as 87.4dB. (2) Ground section According to actual measurement data from Jingjiang Park station to Lianhua Road station of Shanghai Metro line 1, the subway vibration source intensities at ground section are summarized in table 5.4-8. Table 5.4 -8 Analog monitoring results of ground section vibrations from Jinjiang Park Station to Lianhua Road Station Measurement VLz10(dB) Analog conditions times 7.5m 15m 30m Speed Subgrade Fastener 1 76.4 69.9 64.3 2 77.8 72.1 65.9 National 3 77.6 71.3 65.5 Subgrade Railway 60 - 65km/h height of 4 77 70.7 64.8 elastic strip 0.5m type II 5 76.9 70.2 64.7 Average 77.1 70.8 65 (3) Vibration analog of underground line section The vibration analog monitoring data of underground section from shanghai railway station to Zhongshanbeilu Road station of Shanghai Metro line 1 are shown in table 5.4-9.

(III) Prediction and assessment of vibration environment impact (1) Prediction methods The generation and propagation of subway vibration is very complicated process which is related to many factors including subway train structure, performance and traveling speed, structures and materials of track and tunnel structures and geological conditions along the line. The vibration prediction, based on present status monitoring, adopts the vibration predication model in HJ453-2008Technical Guidelines for Environment Impact - Urban Rail Transit and combination method of analog survey and test for prediction with analysis, analog and calculation survey methods in combination with the engineering actual and environment features of this line. The vibration predication mode is as follow: VLz = VL0 +ΔLt +ΔLs +ΔLr+ΔLp+ΔLc+ΔLst +ΔLb (Formula 5-1) Where: VLz——Predicted vertical Z vibration level of outdoor (or indoor) of buildings, dB; VL0——Vibration source intensity of standard line, dB; ΔLt——Correction of axle load of train car, dB; ΔLs——Correction of train traveling speed, dB; ΔLr——Wheel and train condition correction, dB; ΔLp——Correction for ballast bed and fastener, dB; ΔLc——Correction of tunnel structure, dB; ΔLst——Attenuation from distance diffusion and media absorption, dB; ΔLb——Correction of building type. (2) Prediction parameters As shown in formula 5-1, the building outdoor (or indoor) vibration level and the source intensities of standard line closely relate to the traveling speed, wheel and track conditions, ballast bed and fastener type, tunnel structure type, distance absorption and other factors, and separately describe as follows: A. Vibration source intensity of line section 195      The source intensity VLzmax of underground line section of the project is 87.4dB (train speed of 60km/h; 0.5m from outer line). B. Correction of vehicle axle load (ΔLt)    W1 Lt  20 lg W0 (Formula 5-2) Where: W0——Analog vehicle axle load 16t; W1——Zhengzhou subway line 3 vehicle axle load 16t, ΔLt=0. C. Traveling speed correction (ΔLs) Under normal speed (20 - 100km/h), the vibration speed correction ΔLs is as follow: v Ls  20 lg v0 (Formula 5-3) Where: v0——Reference speed (km/h), taken as 60 km/h; v ——Train traveling speed (km/h) . That is, the vibration level increases for 6dB each when the train speed doubles. D. Correction for wheel and track conditions (ΔLr) The irregular wheel and track surface may lead to contact vibration of wheels and rails; when the train passes discontinuous steel rail, it may generate impact vibration. They also will increase the vibration level under the rail. The table 5.4 -10 lists the vibration correction under different wheel and track conditions. Table 5.4 -10 Vibration correction ΔLr under different wheel and track conditions (Unit: dB) Wheel and rail conditions Vibration correction ΔLr Seamless line, round wheel, smooth steel rail 0 surface Short rail circuit, not round wheel and not 5 - 10 smooth steel rail surface E. Correction for ballast bed and fasteners (ΔLp) The vibration correction of different ballast beds and fasteners are summarized in table 5.4 -11. 196      Table 5.4 -11 Vibration correction of different ballast beds and fasteners ΔLp (Unit: dB) Type of ballast bed structure and track fastener ΔLP Average Normal integrated ballast bed 0 0 LORD type fastener -5 - -7 -6 Elastic supporting block type integrated ballast -8 - -12 -10 bed III type track vibration damper fastener -8 - -10 -9 Rubber floating slab ballast bed -15 - -25 -20 New type integrated damping fastener -11 - -15 -13 (Vanguard fastener) Steel spring floating slab ballast bed -20 - -30 -25 F. Correction of tunnel structure (ΔLc) The vibration corrections of different tunnel structures can be determined according to table 5.4 -12. Table 5.4 -12 Vibration correction of different tunnel structures ΔLc (Unit: dB) No. Tunnel structure type ΔLc 1 Rectangular tunnel +1 2 Single bore single line tunnel 0 3 Single bore double line tunnel -2 4 Station section tunnel -4 G. Distance attenuation and medium absorption (ΔLst) The vibration energy attenuates with the distance diffusion. The attenuation law is affected by geological conditions and varies for the geological conditions of different zones. The along-line sites of Zhengzhou rail transit Line 2 project is of tectonic denudation hills and alluvial plain geomorphic unit and the geological conditions are similar to Shanghai. In reference to existing vibration attenuation laws and study results of Shanghai Metro, the distance attenuation and medium absorption ΔLst of vibration assessment of the project are calculated with following formula: a. Ground at both sides of tunnel (L≥5m) Lst  20 lg R  12 (Formula 5-4) b. Ground above tunnel top (vertical) (L<5m) H Lst  20 lg H0 (Formula 5-5) 197      Where: R——Straight line distance from prediction point to tunnel bottom outer line centerline, R  L  H , m; 2 2 L——Horizontal distance from prediction point to outer rail centerline, m; H0——Distance from tunnel top to steel rail top face (m), taken as 5m for single line tunnel; H——Distance from tunnel rail face and ground (m) . c. Ground line r Lst  15lg 7.5 (Formula 5-6) Where: r——Straight line distance from prediction point to outer rail, m; H .Correction for different building types (ΔLb) The responses of different buildings to vibration are different. In general, the reinforced concrete frame buildings with large mass and quality foundation (more than 8-10 floors) have large attenuation of vibration, and classified as category I; the brick-concrete structure buildings with normal foundation (3-8 floors or good quality one-storey house, 2 – 3 floors residence) are classified as category II; The low and old buildings with poor foundation or light structure housing with the natural vibration close to the ground surface and apt to resonance after excited and generating amplification effect of vibration are classified as category III. The vibration corrections of various buildings are shown in table 5.4 -13. Table 5.4 -13 Vibration correction amount of different building categories ΔLb (Unit: dB) Vibration Building Building structures and features correction value type ΔLb Frame structure buildings with quality foundation (highrise I -13 - -6 building) Brick-concrete structure building with normal foundation (middle II -8 - -3 level building or quality low building) Light and old house with poor foundation (poor quality low-rise -3 - 3 buildings and simple temporary building) (3) Predictive assessment amount The predictive assessment amount of vibration of sensitive spots along the line such as resident housing, school and hospital is taken as VLz10 (dB); the predictive assessment amount of vibration of historic and culture sites to be protected is taken as V(mm/s), and the noise predictive assessment amount of secondary structures for sensitive spots within 10m from outer line centerline right above the subway is taken as weighted sound pressure level Lp (dB). 198      (4) Prediction technical conditions A. Train speed Design maximum operation speed: 80km/h. B. Operation time Day time operation period: 6: 00 - 22: 00, totaling 16h; night time operation periods are separately of 5: 00 - 6: 00 and 22: 00~23: 00 totaling 2h. C. Vehicle model selection Adopt A type vehicle, 6 cars marshalling for initial stage, short term and long term with 4 power cars and 2 trailer cars. D. Line technical conditions Steel rail: 60kg/m for main line and 50kg/m for car depot line. Lay long steel rail seamless line along the line. Fastener: adopt elastic split type fastener. Ballast bed: integrated ballast bed for main line, double layer gravel ballast bed for test run line. (5) Prediction formula of environment prediction According to above subway vibration source intensity, prediction mode and various prediction parameters, the ambient vibration prediction formula of Zhengzhou subway line 3 is as follow: A. Ambient vibration predication formula of outdoor ground surface at both sides of underground section tunnel (or indoor) is as follow: V VLz10  84.2  20 log  Lc  20 log L2  H 2  12  Lb V0 (Formula 5-7) B. Environment impact prediction formula of outdoor ground surface above tunnel top in underground section (or indoor) V H VLz10  84.2  20 log  Lc  20 log  Lb V0 H0 (Formula 5-8) C. Prediction formula of outdoor ground surface environment vibration on ground section V r VLZ 10  77.1  20 log  15 log V0 7.5 (Formula 5-9) 199      (6) Vibration prediction results and assessment A. Vibration impact range prediction of rail transit According to above mentioned prediction methods and vibration standard of this assessment, the standard-reaching protection distances of ground vibrations at both sides of line refer to table 5.4 -14.

As shown in table 5.4 -14: the ground surface vibration in areas out of the range 20m from subway outer rail centerline of underground line section along the line can meet the standard requirements of “both sides of arterial traffic”, “mixing area, CBD” and “industrial concentration area” in GB10070-88 Standard of Vibration in Urban Area Environment; the ground surface vibration in areas out of the range 38m from subway outer rail centerline can meet the standard requirements of “residential and culture education area” in GB10070-88 Standard of Vibration in Urban Area Environment. In reference to related regulations in Subway Design Specification (GB 50157-2003) and in combination with the actual conditions of this project, the planned control requirements are provided as follows: a. For “mixing area, CBD”, “industrial concentration area” and “both sides of traffic arterial road”, the building protection distance at both sides of underground line is 25m. b.

R= L  H 2 2 224      b. Evaluation and analysis of prediction results of environment vibration As shown from table 5.4 -15: After project is put into operation, the vibration value VLz10 of 161 environment sensitive spots along the line is 54.6~77.7dB at daytime with 0~ 25.4 dB increment than that at present, and 0.3~26.9 dB increment at nighttime. The environment vibration of 6 sensitive spots exceeds the standard requirements, in which there are 1 sensitive spots with the vibration level exceeding the standard value at daytime with the over-limit amount of0～2.7dB, 6 sensitive spots with then noise level exceeding the standard value at nighttime with the over-limit amount of 0.1～5.7dB; and the over-limit rate is up to3.7％. Among others: The Dongyinggang village sensitive spot exceeds the standard requirements at day night,is located “industrial concentration district”. Due to the line passes just under the sensitive spot, all residents move out within 5m range at both sides of line; the environment vibration prediction value of the first residential building after removal is about 77.7 dB. In contract to GB10070-88 Standard of Vibration in Urban Area Environment, the noise level of this sensitive spot exceeds the standard requirement; the over-limit amount is 2.7 dB at daytime and the night over-limit amount is 5.7 dB. c. Prediction results and analysis of vibration speed There is no subway vibration source around the culture relics along the line in this project.

Prediction result analysis and assessment c As shown by the prediction results in table 5.4 -18, the indoor secondary structure noises in 38 sensitive buildings within 10m range from right above of project underground section to outer rail centerline are in the range of 38.7~56.2dB dB dB. In reference to standard reference limit of “42dB(A)”, there are total 32sensitive spots affected by secondary structure noise due to subway vibration with the over-limit amount of 0.5~14.2dB. 5.4.3 Ambient vibration protection measures 5.4.3.1 Suggestion for vibration pollution control measures during construction period To minimize the construction vibration environment impact in the project sections, it is necessary to take effective control measures from following aspects: (1) Scientifically and reasonable layout of construction site Scientifically and reasonable layout of construction site is an important approach to reduce the construction vibration. Under the premise of guarantee of construction works, it is necessary to fully consider the position relationships between construction site layout and ambient environment. Concentrate the fixed vibration source in construction sites such as processing workshop and material yard to minimize the vibration disturbance scope. In case of long construction period, it is possible to take some emergency vibration damping measures and make full use of natural conditions of topography and land features so as to reduce the impact of vibration propagation on surrounding sensitive spots. The traveling paths of construction vehicles, especially the heavy transport vehicle shall avoid the vibration sensitive areas as possible. (2) Scientific management and civilized construction Under the conditions to guarantee construction progress, optimize the construction program, reasonably arrange the operation time, carry out the high vibration works in the time period with high ambient vibration background value (7:00 - 12:00, 14:00 - 22:00) and limit the construction works with heavy vibration pollution at night time to realize civilized construction. (3) Optimal construction method For the interval section with shield construction method, it is necessary to carry out detailed survey and make the record for the sensitive spots near the tunnel in advance, and take preventive measures such as reinforcement to prevent possible building cracking and ground settlement. 231      (4) During construction period, prepare complete monitoring program for culture relics and ancient architectures affected, focus on the monitoring of their settlement, tilting and crack development, define the pre-alarm value, alarm value and control value and prepare the construction emergency plan; renovate the key buildings in advance; conduct the retaining protection for the building with poor stability; protection measures for the sections near or passing under ground buildings: except reasonable adjustment of parameters such as soil chamber pressure, jack pushing force and grouting pressure during shield propelling, reduction of disturbance for surrounding soil mass as possible and control of surrounding stratum deformation, conduct grouting reinforcement for stratum around the ancient building foundation if necessary so as to enhance the bearing capacity and further control the ancient building deformation. (5) The construction unit and environment protection department shall properly conduct the promotion works and strengthen the environment management awareness of construction unit. According to national and local related laws, regulations, codes and rules, the construction unit shall actively accept the monitoring management and inspection of environment protection department. It is necessary to designate special person to take charge during engineering construction and supervision so as to ensure the implementation of construction vibration control measures. 5.4.3.2 Suggestion for vibration pollution control measures during operation period (I) General Principles of vibration pollution prevention To relieve the disturbance of this project on ground and building along the line, in combination with predictive assessment and analysis results and based on the principle of technical feasibility and economical rationality, conduct vibration reduction design for vehicle types, track construction and line conditions according to production mechanism of subway vibration so as to reduce the vibration source intensity value produced from wheel and rail contact and fundamentally relieve the impact of rail transit vibration on ambient environment. This assessment puts forth the protection measures and suggestions from following aspects: (1) Vehicle vibration control The vehicle performance directly influences the size of vibration sources and the vibration reduction design of vehicle structure is important to control the rail transit vibration. According related study data at home and abroad, the application of elastic wheel can reduce the vibration for 4 - 10dB. In addition, it is possible to use damping wheel or wheel with special tread; take vibration reduction measures on bogie; reduce the primary and secondary suspension system quality; adopt measures such as disc brake to reduce the vehicle vibration. In vehicle model selection of this project, it is recommended to mainly consider, except dynamic and mechanical performance of vehicle, the vibration protection measures and vibration indexes. It is preferable to select the vehicle with low noise and vibration values and quality structures. (2) Vibration control of track structures 232      The vibration control of track structures mainly include the steel rail and line type, fastener type and ballast bed structure, which are separately described as follows: A. Steel rail and line type The 60kg/m steel rail seamless line can not only improve the track stability, reduce the service and maintenance work load and the vehicle operation energy consumption, but also reduce the train impact load, so it is widely applied in urban rail transit. The main line of this project adopts 60kg/m steel rail seamless line, of which the vibration under round wheel conditions is 5-10dB lower than that of short rail line. B. Fastener type The sections in this project with high vibration damping requirements shall adopt Vanguard vibration damping fasteners or GJ-III track vibration damper fastener. C. Ballast bed structure The underground line sections in this project with high vibration damping requirements shall adopt elastic supporting block type integrated ballast bed, of which the installation is inconvenient; in the section with special vibration reduction requirement, it is possible to use steel spring floating slab ballast bed. (3) Maintenance of line and vehicle The smoothness and roundness of subway line and wheel directly affect the size of subway vibration level and the good wheel and rail conditions can reduce the vibration for 5 - 10dB. So it is necessary to intensify the maintenance and service of wheels and rails, regularly lathe the wheel and grind the steel rail and apply oil on small radius curve section for protection so as to ensure good operation conditions and reduce the additional vibration. (II) Vibration pollution control for over-limit sensitive spots (1) Comparison and selection of vibration reduction measures and related principles The comprehensive comparison of construction costs, vibration reduction amount, difficulties of construction and maintenance of vibration reduction measures of different tracks are shown in table 5.4 -19. 233      Table 5.4 -19 Comprehensive comparison of vibration reduction measures of different tracks Elastic supporting GJ-III track vibration Vanguard vibration Vibration reduction type block type integrated LORD fastener Floating slab track damper fastener damping fastener ballast bed Combine the rail support It mainly uses the Make use of the plate, porous rubber and Directly separate the steel rubber tie plate under rubber tie plate under vulcanized base plate rail and ballast bed and Locate the ballast bed plate Structure features and at side of short and at side of steel and make use of make use of rubber on steel spring pad sleeper for track rails for track compression support at steel rail side vibration damping vibration damping deformation of rubber for vibration damping for vibration damping Average of predicted vibration reduction effect 10 9 6 13 25 (dB) Construction cost estimation (increment, 200 130 100 400 1000 10,000 Yuan/single line km) At least once to twice At least once to twice Replace after wearing or Replace after wearing or At least once to twice full Service life full replacement in 50 full replacement in 50 falling off of rubber falling off replacement in 50 years years years support Impact of replacement on Possible impact No impact Possible impact No impact Likely impact operation The floating slab can be cast in place, requiring Same to normal integrated Large construction Same to normal Same to normal special construction Construction feasibility ballast bed, difficulty integrated ballast bed integrated ballast bed machines and tools, with interchangeable large construction difficulty and proven technologies Inconvenient Convenient Maintainable with less Maintainability Maintainable Convenient maintenance maintenance maintenance maintenance work load Practicalness (subway General application England, America, Italia, Europe and America, Beijing subway line Canada, Malaysia, application country or abroad, Shanghai, Spain, Hongkong, Hongkong, Guangzhou, 5, line 10 Shanghai M4 city) Beijing, Guangzhou Guangzhou Beijing 234      According to application examples of urban rain transit vibration control at home and abroad, refer to the requirements in GB50157-2003 Subway Design Specification and HJ453-2008 Environmental Impact Assessment Technology Guidelines - Urban Mass Transit, and considering the large noise of secondary structure due to subway vibration during train passing, the measures principles in this assessment refer to the class 1 standard of residence bedroom, quiet room with special requirements in school and hospital ward in GBJ118-88 Sound Insulation Design Standards for Civil Architecture: indoor noise of residence, classroom and hospital: ≤40dB(A), and regard this as the standard limit of secondary structure noise during train passing period. the basic principles for vibration reduction measures used are as follows: A. For historic and culture sites to be protected and the buildings to be managed according to culture relics requirements, adopt steel spring floating slab integrated ballast bed or equivalent moderate shock-absorbing measures. B. For the sensitive spots such as school, hospital, residential area passing by the line (the right above of track is in 10m range from the outer rail centerline), adopt adopt steel spring floating slab integrated ballast bed or equivalent moderate shock-absorbing measures. C. For the sensitive spots such as school, hospital, residential area with the over-limit of 10dB of secondary structure noise during train passing period or VLzmax over-limit amount of more than 7dB, adopt steel spring floating slab integrated ballast bed or equivalent moderate shock-absorbing measures. D. For the sensitive spots such as school, hospital and residential area with the VLzmax over-limit amount of no more than 3-7dB, adopt Flexible short sleeper and monolithic track bedb,or The same level of vibration reduction measures.. E..For the sensitive spots such as school, hospital, residential area with VLzmax over-limit amount of more than 3dB, adopt GJ-III vibration reduction fasteners or equivalent moderate shock-absorbing measures. In the view of continuous technical advance, the vibration reduction measures suggested by environment impact assessment can be adjusted to other proven vibration damping measures with equivalent effect, ease for maintenance and less construction cost according to domestic and international technical conditions at time of project construction. (2) Vibration reduction measures and investment estimation The vibration reduction measures recommend by the evaluation are as follows: For three cultural relics protection units of Shanhaimomuduha Tomb ,Zhengzhou Memorial Tower for February 7th Strike, Zhengzhou Confucius Temple and 235      Zhengzhou Shang Dynasty Relics 4 along both sides of the line in this project, set the steel spring floating slab ballast beds or equivalent moderate shock-absorbing measures., totaling 780m at both sides and requiring 1.95million yuan investment. For 38 over-limit sensitive spots where the line passes just through (in 5m range from the outer rail center line just above track) such as school, hospital and residence areas, including RCC family member courtyard (Gadameilin district) so on, arrange the steel spring floating slab integral ballast beds, totaling 7052m at both sides and requiring investment of 105.78 million yuan. For 45 over-limit sensitive spots within 10--15m range mainly including City bus company, family member courtyard, and Tianxiu courtyard so on, use the flexible support block type integral ballast bed or equivalent moderate shock-absorbing measures, totaling 8753m for double line and the investment of 87.53 million yuan. For the environment sensitive spot with over-limit environment vibration VLz10, or VLz10 is qualified, but VLzmax exceeds the standard environment requirements, including 28 locations of Peaceful residential homes, Building 8 and so on,, use type III vibration reduction fasteners or equivalent moderate shock-absorbing measures, totaling for 5239m m and investment of 17.45 million yuan. The detailed vibration pollution control measures refer to tables 5.4-20 and 5.4-21. The implementation of preferable removal measures requires the project vibration protection investment of 3# line of 212.71 million yuan, including vibration reduction investment for cultural relics protection of 1.95 million yuan and the vibration reduction investment for sensitive spots such as residence community of 210.76 million yuan, while excluding the engineering demolition and resettlement fee. 236      Table 5.4-20.Table Of Sensitive Point Vibration Control Measures Superscalar Mileage of Relation Total Superscalar of Structural Sensitive ship with Prediction Structural Sensitive Point Lengt investment( VLZma VLZ10 of VLZmax    noise Point SN  Target Name  Mileage  the line Location  point noise Vibration Control h Ten x(dB)  （dB)  prediction  Vibration (m)  position Location  prediction  Measures  thousand Using Control （m）  Day  Night  Day  Night  yuan)  function Measures  New Hope Ao Garden, 17 1  K00‐195～K00‐472  47  Right  House  Outdoor 0.5m 59.0  54.6  /  /  /  /  /  #, 3 #          Fuwa beauty area, Building adopt  GJ‐III  2  K00+843～K00+921  18  Left  House  Outdoor 0.5m 69.5  55.2  /  /  /  /  /  3, Building 1,  vibration  reduction  Taili community, Building fasteners  or  3  K00+940～K00+968  16  Left  House  Outdoor 0.5m 68.1  56.0  /  /  /  /  /  K0+793 ～ 1,  equivalent  357  178.5  K1+150  moderate  Hongda district, 11 #, 10 #, 4  K00+986～K01+100  18  Left  House  Outdoor 0.5m 69.7  56.4  /  /  /  /  /  shock‐absorbing  9 #, 5 #

Scientifically plan the layout of buildings to arrange the first row buildings near the vibration sources as vibration non-sensitive building such as commercial and office building. In combination with the modification of old town, firstly demolish the residential houses near the vibration source, and, in combination with the greening design and re-arrangement of buildings, reserve the vibration prevention distance for newly developed buildings so as to ensure the impact on sensitive buildings within allowable range of standard. 5.4.4 Assessment summary (1) Assessment and analysis of environment vibration prediction results After project is put into operation, the vibration value VLz10 of 161 environment sensitive spots along the line is 54.6~77.7dB at daytime with 0~ 25.4 dB increment than that at present, and 0.3~26.9 dB increment at nighttime. The environment vibration of 6 sensitive spots exceeds the standard requirements, in which there are 1 sensitive spots with the vibration level exceeding the standard value at daytime with the over-limit amount of 0～2.7dB, 6 sensitive spots with then noise level exceeding the standard value at nighttime with the over-limit amount of 0.1～5.7dB; and the over-limit rate is up to3.7％. (2) Prediction results and analysis of vibration speed The structure maximum speed response values of two cultural relics protection sites in this project as Shanhaimomuduha Tomb ,Zhengzhou Memorial Tower for February 7th Strike, Zhengzhou Shang Dynasty Relics and Zhengzhou Confucius Temple along the line exceed the standard requirements and the over-limit amounts are separately of 1.57mm/s、1.18mm/s、0.96 mm/s. (3) Prediction results and analysis of secondary structure noise The indoor secondary structure noises in 38 sensitive buildings within 10m range from right above of project underground section to outer rail centerline are in the range of 38.7~56.2dB dB dB. In reference to standard reference limit of “42dB(A)”, there are total 32sensitive spots affected by secondary structure noise due to subway vibration with the over-limit amount of 0.1~14.2dB dB. 256      5.4.5 Suggestion of pollution control measures (1) In the vehicle model selection of this project, besides the dynamic and mechanical performance, it also focuses on the vibration protection measures and vibration indexes. It is preferable to select the vehicle with low noise and vibration values and quality structures. (2) The 60kg/m steel rail seamless line for project design has positive effect on prevention of vibration pollution. (3) The operation unit shall intensify the maintenance and service of wheels and rails, regularly lathe the wheel and grind the steel rail, and apply oil on small radius curve section for protection so as to ensure good operation conditions and reduce the additional vibration. (4) In this project, there are totally 161 susceptible places to installed with GJ-III track vibration damper fasteners or equivalent moderate shock-absorbing measures in the length of 5239m (dual lines), elastic supporting one-piece track bed or equivalent high-level shock-absorbing measure in the length of 8753m (dual lines), and steel-spring floating-plate track bed in the length of 7182m (dual lines), so requiring investment of RMB 212,710,000. (5) During subway operation period, it is necessary to prepare complete monitoring program for culture relic protection unit, timely feed back the monitoring information. If any problem is found, timely take measures to ensure the safety of culture relics. (6) To prevent the impact from subway vibration, according to the regulations in Subway Design Specification (GB50157-2003) and vibration protection distance in this report, the protection distance of buildings at both sides of underground line in “mixing area, CBD”, “industrial concentration area” and “both sides of traffic arterial road” area specified in GB10070-88 Standard of Vibration in Urban Area Environment is 25m; the protection distance of buildings at both sides of underground line in “residential and culture education area” is 38m. 5.4.6 Summary of vibration environment impact assessment The design unit has considered the vibration pollution control issues in project design. This report, in combination with project features and ambient quality present status, puts forth purposeful prevention measures and suggestions from aspects of vehicle model selection, urban planning and management, project operation and maintenance, line and track structure vibration reduction. As long as these measures and suggestions have been completely and carefully implemented, the impact of vibration environment along the line of this project can be controlled within national and Zhengzhou municipal specifications and standards. 257      5.5 Water environment impact predictive assessment and measures of water environment 5.5.1 Surface water predictive assessment 5.5.1.1 Water pollution source (1) Water pollution source during construction period The waste water generated in construction period of this project mainly come from: muddy water from construction works excavation, drilling, construction of continuous diaphragm maintenance structure and shield, washing water of construction machinery and transport vehicles, domestic sewage from construction staff, the surface runoff sewage from flushing capping mass and construction silt and etc. According to survey of construction waste water drainage conditions of rail transit, there are normally about 100 persons in each station (section); calculated with the water consumption of 0.04m3 per person per day, the discharge volume of domestic sewage for construction staff in each section is about 4m3/d. The main pollutants in sewage include COD, animal and vegetable oil, SS, ammonia nitrogen and etc. The construction also discharges the structure curing drainage, the construction site flushing drainage. The COD content in domestic sewage of construction wastewater is high and up to 200 - 300mg/L, and the SS content in washing drainage of construction site is high and up to 150 - 200mg/L. (2) Water pollution source during operation period The sewage during operation period of this project mainly comes from the domestic sewage from the stations along the line, and the oily sewage, washing sewage and domestic sewage generated from car depot and integrated base. A Station Drainage This project will have a total of 21 stations, all underground stations, with a total amount of wastewater discharge beng 771.4m 3 / d. The sewage in the stations mainly includes the fecal sewage in toilets of stations, domestic sewage of staff and the washing sewage of station facilities, of which the water quality of this sewage is simple of domestic sewage. The station sewage is drained into municipal sewage pipeline network and then into local sewage treatment plant for treatment. B. car depot and integrated base The production waste water of Hongjiaozhou car depot and integrated base mainly includes the oily wastewater from vehicle inspection and washing, and vehicle washing sewage, in which the main pollutants are of petroleum type products, COD, BOD5, LAS and etc. in addition, it also includes staff office and domestic sewage 258      such as bathing pool bath water, canteen washing water, cleaning drainage and toilet washing water, in which the main pollutants include BOD5, COD, ammonia nitrogen, animal and vegetable oil. For the water use for the car depot and parking lot of Line 3 of Zhengzhou Metro, see Table 5.5-1. 5.5.1.2 Assessment method The assessment, based on engineering design and in reference to existing study results and analog data, predicts the water quality and water quantity of various pollution sources and analyzes the water quality standard-reaching conditions with standard index method. The expression is as follow: Si,j＝(Ci,j/Co,i) Where: Ci,j——Emission concentration of ith pollutant of jth pollution source (mg/L); Co,i——Assessment standard of ith pollutant (mg/L); Si,j——Standard index at jth point of single water quality parameter i. The standard index of pH is as follow: SpH,j=(7.0 - pHj) /(7.0 - pHsd) pHj ≤ 7.0 SpH,j=(pHj -7.0) /(pHsu -7.0) pHj > 7.0 Where: pHj——pH value of jth pollution source; pHsd——Lower limit of pH value specified in standard; pHsu——Upper limit of pH value specified in standard; SpH,j——Standard index of pH value of jth pollution source. 5.5.1.3 Analysis of water environment impact during construction period The project generates large amount of sediments and dusts during construction period. If not cleaned completely, the residual part will be flushed into sewer with the drainage or rain at construction site. The waste water will increase the sediment contents in surface waters near the construction site and municipal drain pipe, and even lead to sewer silting up, and therefore impact the normal function of municipal drain pipe network and lead to unsmooth rainy season drainage; when there is no municipal sewer line at construction site, the sewage automatically flows to nearby surface waters so that it leads to increase of SS content in received waters and pollution of ambient environment. 259      The construction sites in urban area will temporarily rent the houses and the domestic sewage and production swage are drained into urban sewer line network and surface waters. If the construction period drainage facilities are not complete, the domestic sewage and production sewage are drained into the sewage receipt waters, which impose certain adverse impact on water quality in waters and living environment of aquatic animals and plants. According to the survey of construction sewage drainage of rail transit line, there are normally about 100 construction workers in each section for road construction. Calculated with the water consumption of 0.04m3 per person per day, the domestic sewage drainage of construction staff in each section is about 4m3/d. The main pollutants in sewage are mainly of COD, animal and vegetation oil, SS and ammonia nitrogen The construction also discharges the structure curing drainage, the construction site flushing drainage and equipment cooling drainage. The COD content in domestic sewage of construction wastewater is high and up to 200 - 300mg/L, and the SS content in washing drainage of construction site is high and up to 150 - 200mg/L. Except Hanghai East Road car depot and Boxue Road Station, the municipal drainage pipeline network along the line of this project has been completed; the waste water can be drained into municipal sewage pipeline network or rainwater pipe network during construction period, and it will execute the limits in level 3 standard in Integrated Wastewater Discharge Standard (GB8978-1996). For the areas where the municipal sewage pipe network has not been completed, set temporary toilet pit to collect the domestic sewage, and periodically clear to nearby farm without draining out; the construction waste water will be recycled after sedimentation and not drained out.

There is no centralized drinking water source along the construction line so that it will not impose impact on the earth surface water sources. The construction wastewater is discharged into the settlement pond at site via the pipeline laid in construction site, and then returned to site washing dust suppression and washing vehicles without draining out; the muddy water generated from shield construction will be fully returned through muddy water separation system without draining out. The muddy are dried and then transported out with engineering waste slag to designated place for uniform treatment by Zhengzhou municipal construction waster management department, and will not pollute the water environment. 5.5.1.4 Predictive assessment of water environment during operation period (1) Assessment job contents According to assessment job class, define the job contents of surface water environment impact assessment as follows: A.

Evaluate the designed sewage treatment faculties and provide assessment conclusion and assessment suggestion according to pollution source prediction results; D. Calculate the discharge amount of main pollutants, (2) Environment impact assessment of sewage discharge of car depot &the parking lots The car depot is near Hanghai East Road. The parking depot is at south bank of Jialu River and north of Xinliu Road Station, and equipped with vehicle operation overhauling facilities and general material warehouse. It is responsible for the parking, 261      train technical inspection and routine maintenance and service works such as cleaning and wiping for the vehicles in the line. The drained sewage is mainly of overhauling oily sewage, washing waste water and domestic sewage of working staff. The overhauling oily sewage and washing waste water are of production sewage and the main pollutants are of petroleum type; the domestic sewage is mainly of COD, BOD5, ammonia nitrogen and etc. In the design, the overhauling sewage is treated by the grease trap and the car washing sewage is neutralized, deposited and filtered with the car washing auxiliary facilities before recycling. The normal domestic sewage is treated with the septic tank. The sewages are finally discharged into the municipal drainage pipe network and then the municipal sewage treatment plant for centralized treatment. (I) Prediction of water quality and water volume A. Prediction of water volume According to the design, the maximum water consumption of car depot and the parking lots is 290m3/d, sewage generation volume of 214 m3/d, sewage return volume of 95 m3/d and sewage drainage volume of 119 m3/d. The detailed water balance refers to figure 5.1-1. 新 鲜 水 Fresh water, 生 产 用 水 process water, 生 活 用 水 domestic water, 未 预 见 水 unforeseen water, 绿化用水 greening water, 检修用水 maintenance water, 洗车用水 car wash water, 污水处理站 sewage treatment station, 排入附近沟渠 Discharged into nearby ditches, 耗 consuming 单位：unit Water balance chart of car depot at Hanghai East Road 262      新鲜水 Fresh water, 洗车用水 wash water, 生活用水 domestic water, 未预见水 unforeseen water, 绿 化 用 水 greening water, 化 粪 池 septic tanks, 耗 consuming, 接 入 市 政 管 网 connected to municipal pipe network, 单位 unit Water balance chart of parking lot at Jialu River Figure 5.5-1.Water balance chart of car depot and parking lot B.

(III) Effluent water quality analysis A. Inspection & repair sewage 264      The design adopts adjustment, oil separation and settlement tank to treat the inspection & repair oily sewage. The working principle of adjustment, oil separation and settlement tank is mainly of gravity separation and agglomeration separation with the advantages of high efficiency, quick, stable and less floor area, and is normally used to remove the oil droplets with the diameter of more than with the oil removal efficiency of more than 80%. B. Car washing sewage Part of car washing sewage are recycled after treated with neutralization, sediment and filtration devices affiliated to the car washing device, and the rest is discharged into urban pipeline network. According to related data, in the car washing sewage after treatment of neutralization, sediment and filtration, the pollutant concentrations of CODcr, BOD5, petroleum products and LAS contents are separately of 36mg/L, 2 mg/L, 5mg/L and 0.16mg/L; they can meet the standard requirements of “Car washing water” in GB/T18920-2002 Reuse of Recycling water for Urban--Water Quality Standard for Urban Miscellaneous Water Consumption (BOD5≤10mg/L, LAS≤0.5mg/L) and be recycled for car washing. The rest sewage not recycled also excels the class 3 standard requirements in GB8978-1996. C. Domestic sewage In the design, the domestic sewage is discharged after treatment with septic tank and meets the class 3 standard requirements in GB8978-1996.

The assessment considers the sewage treatment program in design for car depot & the parking lots is feasible. (3) Environment impact assessment of sewage discharge in stations along the line There are 21 stations along the line of project. The discharged sewage mainly includes office domestic sewage of staff, washing sewage from station facilities cleaning and fecal sewage in station toilets. The total discharge amount of sewage is 160 m3/d. The sewage features simple sewage property and the main pollution factors include CODcr, BOD5, animal and plant oil, ammonia nitrogen and etc. According to field survey and feedback of related department, the sewage of each station during project construction period is able to be included in existing or planned municipal sewage pipeline network and then into related urban sewage treatment plant for centralized treatment (details refer to table 4.1-8). The sewage discharge of each station complies with GB8978-1996 class 3 standard. According to analog analysis of related projects, the average water quality of station domestic sewage after treatment by septic tank is as follow: pH value =7.5 - 8.0, CODCr=150 - 200 mg/L, BOD5=50 - 90 mg/L, animal and plant oil content =5 - 10 mg/L and ammonia nitrogen =10 - 25 mg/L. According to prediction results of sewage water quality and in reference to the assessment standard, adopt standard index method to evaluate the standard-reaching state of station sewage. The assessment results refer to table 5.5-7.

The drinking water sources in Zhengzhou are separately located at north and south of urban area; the north water sources are located at the south bank of Yellow River, separately of Jiuwuyuan water source and Beijian water source; the south water sources are located at both sides of Zhengzhou-Xi’an railway, separately of Changzhuang reservoir and Jiangang reservoir; moreover, the middle main canal of South-to-North Water Diversion Project passes through the southwest out of the central urban area. The rail transit 3# line project is in the central urban area, while the drinking water source protection areas are out of the central urban area, so the stations, car depot and parking depot in this project do not involve Zhengzhou drinking water source protection areas. 267      5.5.1.6 Mitigation measures for surface water environment impact Properly design the construction site drainage system during construction period. The construction staff fecal sewage are regularly collected and treated by Zhengzhou Municipal sanitation workers after storage of septic tank; the sediment tank is set at construction site outlet and the construction sewage is recycled for field site washing dust suppression and washing vehicles after settlement treatment; the muddy water for shield construction are fully reused after treatment by mud-water separation system. Prohibit the construction site production sewage and domestic sewage directly or indirectly discharged into surface water. The construction site and spoil field must not be set within range of 200m surface water source protection area. The construction waste slag and the dried sludge treated by shield mud-water separation system shall be deposited at specified locations, fenced and timely delivered to local water slag administration for treatment. The construction organization design must be orderly fulfilled during construction and the excavation and fill construction must not be done during rainstorm. In rainy day, it is necessary to cover tarpaulin or equivalent on temporary spoil and materials so as to prevent the spoil soil flowing into surface water and polluting the waters under the flushing of rainstorm. Strengthen the environment protection management during construction period. it is recommended to assign special construction environment protection manager to intensify the implementation of specific environment protection measures and put the prevention first so as to reduce and prevent the pollution on waters. Treat the car depot production sewage with adjusting, oil-separation and sediment tank, and the domestic sewage of 21 stations with septic tank. 5.5.2 Underground water predictive assessment The main assessment contents of underground water are as follows: analyze the impact of project construction on underground water quality and provide the protection measures; analyze the impact of construction rainfall on ground settlement and provide prevention measures; analyze the impact of project construction on underground supply, runoff and discharge. 5.5.2.1 Impact on underground water quality (1) Impact analysis on underground water during construction period Before the construction of the underground station and the interval, the continuous concrete wall is built first in order to block groundwater and act as a maintenance structure. And then on the basis of good anti-seepage work, lay blind pipe on the bottom on both sides of the tunnel to collect and conduct the residual water on to the ground. The water goes through the sedimentation tank set on the ground and discharges into urban sewage pipe network then into the urban sewage treatment plant. In the construction process, drainage water quantity is low, without influence to the 268      underground water . Based on the above analysis, the project construction process has little influence to groundwater. (2) Impact analysis of underground water quality during operation period The waterproof of underground structures of this project complies with standards Technical Specifications for Underground Construction Moisture Prevention (GBJ108-87) and Code for Design of Subway. The subway tunnels and stations have good waterproof performance, so the external pollution sources during subway operation period will not enter the underground water through subway tunnel and station. After construction and put into service of this project, the sewage produced from along-line stations and car depot & the parking lots will be discharged into municipal sewage pipeline network after treated. During generation and transport of sewage, the sewage amount seeping into the underground due to leakage and drop-in is small, and the anti-seepage measures are taken in station facilities such as toilet and septic tank, so it will impose remarkable impact on regional underground water quality. 5.5.2.2 Impact analysis of construction dewatering on ground settlement According to past subway construction experience, if the underground station or underground section adopts open cut or covered cut construction method without any waterproof and waterstop measures, it is necessary to dewater or drain large mass of phreatic water and shallow confined water, which will lead to overall falling of underground level along the construction line and surrounding regions, and therefore the increase of ground settlement volume and settlement rate. So it will lead to the risk of ground settlement and even surface collapse. The line of this project will go beneath the Jinshui River, Xiong’er River, Qili River and other surface water bodies, and the traction lines of the parking lot and car depot will also go beneath the Jialu River and Chao River. The surface water and groundwater are closely related. The construction process should pay special attention to preventing pumping and discharging groundwater from causing nearby surface water leakage as well as the ground subsidence and other disasters brought thereby. (1) Prediction of impact range of construction dewatering Among the project’s 21 underground stations, 20 stations will use the cut and cover construction method. The Jinshui Road Station will use the cover digging method. Each interval will use the shield method as the primary method and the cut and cover method as the secondary method. For the interval structure-related detailed construction plan, see Table 5.5-9.

For the enclosed structure and technical features of shield machine, it can fulfill the works with water without need of unwatering; during construction with open cut and covered excavation method, when the bottom elevation of construction structure is lower than underground water level, it must conduct unwatering works. 271      The unwatering requirements for project construction are listed in table 5.5-10.

(II) Ground settlement impact analysis from construction unwatering For 21 underground stations in project design, the main body enclosure structure during open cut construction of work well adopts underground diaphragm wall or cast-in-place pile enclosure plus jet grouting pile water stop, and the enclosure structure will enter the impermeable stratum under pit foundation. According to construction sequence of station open cut construction, firstly conduct the enclosure structure construction during construction period, and then set well in pit foundation for pit unwatering before excavation so as to ensure the underground water level is about 1-2m lower than pit foundation excavation face, and finally backfill the bottom and well. By analogy with the underground station construction of other cities, under the conditions of safety construction, the settlement along the line is uniform and the settlement different and inclination at both sides of buildings are within the allowable range specified in GBJ7—89 Specifications for Design of Building Foundations. Since this project adopts underground diaphragm wall or cast-in-place pile enclosure plus jet grouting pile water stop for station construction, it only requires pumping out the underground water in the range of construction foundation pit and discharging to nearby rain drainage system so that the underground water levels inside and outside of the foundation pit keep stable. Since the underground diaphragm wall and cast-in-place pile enclosure structures have a remarkable waterproof effect, the unwatering in foundation pits can effectively prevent the underground water loss outside of the foundation pit. Under the conditions of underground diaphragm wall or cast-in-place pile enclosure plus jet grouting pile water stop or similar measures, the possible ground settlements mainly concentrate in 10-20m range around the station foundation pit and the settlement amount around the station is normally no more than 30mm. In addition, the time periods required for construction unwater during subway construction are limited in station construction period, and it will stops when the foundation works complete. The engineering unwatering duration is short and it is implemented along the subway line sections separately, so it has limited impact on urban underground reservoir. The safe unwatering construction of the project will not lead to adverse effect on ground and buildings. 5.5.2.3 Impact analysis of engineering construction on underwater recharge, runoff and discharge This project does not involve any underwater drinking water source protection area. The underground water types of regions along the line of project are mainly of perched ground water, quaternary loose rock type hole water and bedrock crevice water, in which the quaternary loose rock type hole water is the priority. The underground water is mainly supplied from surface waters (including Jinshui River, 277      Xionger River, Chaohe River) with less impact from artificial exploitation. In normal water season and low water season, the underground water feeds surface water and the underwater drains to the surface water; while in flood season, the surface water level rises and the surface water feeds the underground water. The impact of this project construction on underground water feeding is very small. The sectional impact analysis of constructions of underground stations and section tunnels in this project on ground water runoff are as follows: (1) Zone A The section range is from the start point, through Nanyang Road, Erqi Square, East Street, Zhengbian Road to the intersection of line and Longhai Railway, and the mileage range is (K0+0.000~K23+200) and the ground elevation is between 86.70m and 103.10m. The underground water in section from starting point to Longgang is mainly of bedrock crevice water and lack of quaternary loose rock type hole water (perched ground water), and the aquifer is mainly of angular gravel and shallow weathering gaps, receives the infiltration feeding of atmospheric precipitation and discharges to nearby inter-mountain depression. The included angle of underwater trend and underground water runoff is small and the project tunnel will not block the underground water, so it only has limited impact on ground water runoff and drainage in the area. (2) Zone B Zone B: the range is from the intersection of line with Longhai Railway to the destination; the mileage range is (K23+200~K31+350.000) and the ground elevation is between 87.10m and 95.00m. The underground water types in this section are mainly of phreatic water with weak confined property, and the aquifer is mainly of gravel and pebble and side fed by Qili River and other surface waters. The included angle of line direction with ground water runoff direction is large and some aquifer sections is cut off by the tunnel in local sections, so the project tunnel will cut the shallow aquifer in this zone and lead to high banked-up underground level at local area. however, the tunnels only involves partial space of shallow aquifer section and the shallow underground water fabric has good permeability, the ground water runoff path can bypass the tunnel structures through penetration and normally will not remarkably affect the runoff and drainage of regional ground water runoff. In this project, the concrete diaphragm wall is constructed before the construction of underground station and section to block off the underground water and use as the retaining structure. Then based on the proper anti-seepage works, lay out the blank tubing under the channel at both sides of tunnel to collect the residual water to the ground surface; set up the sedimentation basin on the ground; the water is discharged to municipal sewage pipe network and then sewage treatment plant after sedimentation in the basin. During construction of project, the drainage water volume is small with less impact on the underground water. 278      5.5.2.4 Mitigation measures of impact on underground water (1) Protection measures for underground water quality According to the regulations in Law of the People's Republic of China on Prevention and Control of Water Pollution article 14 “While constructing underground engineering facilities or carrying out underground prospecting, mining and other underground activities, protective measures shall be taken to prevent ground water pollution”, following measures are taken in construction and operation periods of this project to prevent ground water pollution: The construction camps shall set septic tanks and equipped with anti-seepage measures to prevent underground water pollution. The domestic garbage generated during construction period shall be subject to centralized management and delivered to municipal sanitation department for collective treatment so as to prevent pollution of underground water source. (2) Suggestion for preventive measures from ground settlement and collapse The construction scale of foundation pit excavation of underground stations is large, so it shall fully consider the adverse factors which may impact the foundation pit stability during construction, and take proper protection measure to ensure the safety of foundation pit construction and surrounding road, underground pipelines and buildings. Intensify the construction monitoring works and strictly monitor the vertical and horizontal displacement of pit foundation and surrounding buildings, stress conditions of enclosure structures, variation of underground waters and the soil pressure. Strive to fulfill informationization construction for ease of timely adjustment of design parameters and construction methods to ensure the construction safety and eliminate the potential hazards. Recommend to intensify the monitoring and supervision of underground water level, flow direction and speed along the line (especially: Zhongxing road~Hanghai east Road). This assessment reserves 500,000 Yuan for setting of temporary sedimentation tank, 600,000 Yuan for monitoring of ground settlement, underground water level and quality. 5.5.2.5 Summary (1) The project does not involve the protected areas of underground water and drinking water resources. (2) Before the construction of the underground station and the interval, the continuous concrete wall is built first in order to block groundwater and act as a maintenance structure. And then on the basis of good anti-seepage work, lay blind pipe on the bottom on both sides of the tunnel to collect and conduct the residual water on to the ground. The water goes through the sedimentation tank set on the 279      ground and discharges into urban sewage pipe network then into the urban sewage treatment plant. In the construction process, drainage water quantity is low, without influence to the underground water . Based on the above analysis, the project construction process has little influence to groundwater. (3) The engineering construction adopts underground diaphragm wall or cast-in-place pile fence and the auxiliary retaining structure adopts cast-in-place pile fence with jet grouting pile for waterproof so as to effectively control the ground settlement. (4) The urban sewage infrastructures along the line are complete and the construction sewage quality is simple. The assessment considers the sewage will not pollute the underground water quality if treated with proper process and collected into nearby municipal pipeline network or waters. (5)The short term falling of local underground water level during construction period will rapidly recover after rainfall completed, and will not affect the underground water resource in the area. 5.5.3 Assessment conclusion (1) The domestic sewage, muddy water and other production wastewater generated from construction stations, car depot and other sites are reused or drained into urban pipeline network after treatment of sedimentation tank, and will not affect the surface water and underground water environment. (2) The sewage amount from car depot and the parking lots is 214 m3/d, in which the sewage reuse amount is 95m3/d and sewage discharge amount is 119 m3/d. The total discharge amount of domestic sewage in stations along the line is 160m3/d. The overhaul sewage of car depot integrated base after treated by oil separation tank, and the car washing sewage after treatment of matching neutralization - sediment – filtration by car washing device, are reused, and the normal domestic sewage is treated by septic tank. The domestic sewage of station is treated by septic tank. The above sewage can be discharged into existing or planned municipal sewage pipeline and then into municipal sewage treatment plant. The drainage water quality can meet the requirements of level 3 emission standard in GB8978-1996. (3) The current water quality of the Jinshui River, Xiong’er River and Qili River the line passes by can reach requirement for water quality category IV in “Quality Standard for Surface Water” (GB3838-2002) . The major water quality indexes of the current underground water can meet the requirements for water quality category III of “Quality Standard for Underground Water” GB/T14848-93. (4) The project runs beneath surface water bodies such as Jinshui River, Xiong’er River and Qili River etc. in the form of tunnel(constructed with shield tunnel method), and does not run across the protected areas of water resources. The project construction will not cause direct influence on the water quality of the water source and the water intake. (5) In case the pollutants such as oil etc. enter into underground water during project construction, the underground water quality in the area may be influenced to some 280      extent. However, the influence on the underground water quality due to construction may be lowered to the minimum level in case of scientific, rational and orderly management of the whole course of construction. No influences will be caused on the underground water quality during the project operational period. (6) The engineering construction adopts underground diaphragm wall or cast-in-place pile fence and the auxiliary retaining structure adopts cast-in-place pile fence with jet grouting pile for waterproof so as to effectively control the ground settlement. (7) The urban sewage infrastructures along the line are complete and the construction sewage quality is simple. The assessment considers the sewage will not pollute the underground water quality if treated with proper process and collected into nearby municipal pipeline network or waters. 5.6 Ecological environment impact assessment and ecological environment protection measures This project is located in urban area of Zhengzhou city and the project scope is mainly of urban regional ecological system. According to the requirements in HJ453-2008 Technical Guideline of Environment Impact Assessment - Urban Rail Transit and the ecological sensitivity of project line and areas, carry out predictive assessment of ecological environment impact. The assessment works highlight the urban ecological environment features as complete, objective and correct as possible to reflect the impact of project to be built in ambient environment, and focuses on the local sensitive ecological issues and typical factors which may generate significant impact and puts forth the prevention and recovery measures of ecological impact. 5.6.1 Predictive assessment 5.6.1.1 Assessment principle (1) From the view of regional ecological function impact, focus on the ecological function of related urban planning and ecological planning for assessment; (2) According to features of urban ecological environment, carry out selective analysis fir the ecological factors such as land utilization and urban landscape on rail transit construction; (3) Predict and analyze main environment impact of project to be built for urban ecological sensitive area, and analyze and describe the possible ecological variation by engineering construction. 5.6.1.2 Assessment contents, emphasis and protection object (I) Assessment contents (1) According to urban development planning and function orientation of regions 281      along the line, in view of urban planning layout, traffic planning and other related planning, comment the relationship of this project with urban planning and urban group, and carry out analysis of related planning conformity and ecological suitability of project line; (2) Evaluate the variation of regional land utilization function and loss of greenland, vegetation and rare species; (3) Impact of engineering waste slag and treatment method on urban ecological environment; prediction and analysis of possible water loss and soil erosion; (4) Ecological structure stability and variation trend of species diversity within range of prediction analysis assessment, describing the impact of project on ecological structure, function and disturbance recovery capability in assessment range; (5) Impact analysis of buildings such as project stations and ventilation pavilions on urban landscape.

Assessment critical content: compatibility of project and urban planning; coordination analysis of ground building landscape and urban landscape including station entrance/exit and ventilation pavilion; impact of project on ecological sensitive objects. (III) Protection object (1) Protection object of ecologic environment during construction period The construction site, construction unit premise and construction facility will occupy the land, destroy the ground surface vegetation and impact the urban ecology and urban landscape. The protection object during construction period is the urban green land. (2) Protection object of ecologic environment during operation period After the project is put into the operation, the main protection objects are of urban landscape; it shall ensure the harmony and unity of newly built artificial building of the project with the natural landscape and artificial landscape of surrounding city and set up the human oriented service concept to benefit the virtuous cycle of urban ecological system, contribute to establishment of “Ecological city” and ensure the sustainable development of city. 5.6.1.3 Assessment method The present status assessment of ecological environment adopts the combination method of qualitative and quantitative analysis to analyze the ecological completeness 282      of regional environment and evaluate the regional land utilization features and immunity capacity; the predictive assessment plans to adopt related principles of landscape ecology and architectural aesthetics to analyze the impact of ground buildings such as station entrance/exit, ventilation pavilion, car depot, repair depot and main substation on ambient environment as well as the coordination of project ground buildings with urban landscape. 5.6.2 Analysis and protection measures for urban ecological environment impact 5.6.2.1 Impact analysis of land acquisition and demolition of project construction on ecological environment (I) Type and volume of project land acquisition and demolition The land acquisition and demolition at early stage of this project features long line, many points and wide range. Since the project transverses the core zone in city center, to reduce the land acquisition and demolition works, many stations are located in the middle of road. However, most of stations are within the range of main urban roads and downtown area and many transfer stations needs to be constructed at same time, so it still involves a wide range of removal and relocation range to meet the requirements for station layout, construction, social traffic and pipeline relocation. The removal and relocation housing properties mainly include downtown area office building, mature community, school, downtown area store and etc. so the land acquisition and demolition features in this project are as follows: favorable lot for housing demolition, large number of households, great removal and relocation difficulty, high relocation cost and wide impact range. The total demolition area along project line is 10.2 hm2, permanent land use of 5.98hm2 and temporary land use of 30.08hm2. The temporary ground is temporarily occupied during open cut construction method for underground stations. By investment and statistics, the total land occupation of this project is 829.68 Mus, including expropriated collective land of 786 Mus and expropriated state land of 43.68 Mus. The expropriated collective lands are of vegetable plot, cultivated land, orchard and forest land at present. The expropriated state lands are of state construction land.

The land acquisition and demolition is a complicated systematic engineering widely involved, and the works directly influence the project progress. Based on the experiences of similar project, the employer can establish special agent or entrust other unit to specifically take charge of the land acquisition and demolition works of this project. According to Regulations on management of Zhengzhou Urban Construction Dismantlement (revised in 2005), Zhengzhou Municipal People’s Government Administrative Department fulfills the supervision and management of demolition works of urban houses, the district people’s government real estate administrative departments are responsible for the houses demolition management works in own district according to the duty allocation. (III) Environment impact analysis for demolition and placemen In general, the land acquisition and demolition amount involved in Zhengzhou rail transit 3 line phase I project is small due to full underground layout of the project, and the Zhengzhou Municipal Government will, according to related compensation and placement policies for land acquisition and demolition, properly arrange and reasonably compensate the masses affected by the land acquisition and demolition for rail transit construction, and guarantee their legal rights and benefits. The disputes can be effectively avoided or solved provided that it fulfills the compensation according to actual conditions of Zhengzhou city and related laws and the proper public participation. For the user of houses demolished, make overall arrangement with the principle of in favor of implementation of urban planning and urban old zone modification according to the requirement for construction areas in urban planning and the construction project property. If the residents have other houses in urban or have planned to purchase other houses, the money compensation for demolished houses will be helpful to improve their economic status and enhance the quality of life. In addition, the urban planning department will control the construction project land use according to this planning and avoid new land acquisition works as possible during implementation of this project. As indicated in above conditions, after taken proper placement measures, the adverse impact from demolition is limited, and the land acquisition and demolition problems due to rail transit construction can be properly solved with small impact on urban social environment. 285      5.6.2.2 Impact analysis of engineering construction on urban ecological function areas According to Zhengzhou Eco-city Construction Planning, the entire city is divided into 5 class I ecological function areas of northwest Mangshan Mountain Landscape Ecological Tourism Zone, southwest Loess Hilly and Gully Water Conservation Zone, Yellow River Beach Wetland Ecological Protection Zone, southeast Plain High Efficient Ecological Agriculture Development Zone and middle Human Production Activities Zone. On this basis, it specified 15 class II ecological function areas and 84 class III areas, and put forth related classified control planning for ecological protection. The planning line is mainly in middle Human Production Activities Zone. The line is laid under the existing (or planned) roads and the domestic sewage generated from its stations and car depot & integrated base is discharged into municipal pipeline network and then to the urban sewage treatment plant so that it will not lead to pollution of surface waters. At same time, the features of rail transit of less land occupation and high passenger traffic volume can effectively solve the urban traffic congestion problems, relieve the pressure on road traffic and reduce the road traffic construction land use, and therefore play an active role in optimization of urban and industry space layout. Thus, the construction of rail transit will effectively relieve the ecologic problems such as unreasonable land use structures in Zhengzhou urban ecological function areas and basically will not impose adverse impact on ecological function of various ecological function areas. The Construction-forbidden areas in Zhengzhou include: Yellow River wetland, core area of national protection area and landscape ad famous scenery (including Songshan World Geopark, Henan Songshan National Forest Park, Zhengzhou National Forest Park, Xinzheng Shizu Mountain Forest Park, Henan Songbei Forest Park, Gongyi Qinglongshan Forest Park, Zhongmou Forest park, Henan Songshan Scenic Spot, Zhengzhou Yellow River Scenic Spot, Fuxi Mountain – Huancui Valley Scenic Spot), basic farmland preservation area, geological disaster prone areas (including debris flow prone areas, mine goaf), underground mineral reserve distribution area, underground cultural relics burial area, water source protection zones (including surface water drinking water source protection zone, south-to-north water diversion project class I protection zone, underwater source core zone, river headwater, river and lake wetlands), main floodwater drawoff passage, large scale infrastructure gallery and its control belt (including west-east natural gas transmission trunk line, Zhongyuan Oil field long distance transport pipeline, Yima coal-gas long distance transport pipeline, Lanzhou-Zhengzhou-Changsha and Jinzhou-Zhengzhou oil pipeline, high voltage power transmission line). Except Jialu River parking depot, the rain transit 3 line phase I project is within the urban built-up area and planning area and does not involve the construction control area and construction-forbidden area range in the ecologic function zone planning. The land use of Jialu River parking depot is of normal construction land, not of construction-forbidden zone. 5.6.2.3 Impact analysis of engineering construction on the vegetations and urban green lands along the line (I) Impact on vegetation along the line 286      In comparison with urban ground traffic, the construction land occupied for urban rail transit is far less and the urban construction land scale along project line can be effectively controlled. The project line is mainly laid along existing road so that it can minimize the urban green land occupation while relieving the ground traffic, and also benefit for the construction and recovery of urban ecological infrastructures such as green land so as to improve the urban landscape. (II) Impact on urban green land The urban green land occupation of the project is mainly of the occupation of road greening belt by ground buildings such as station entrance/exit and ventilation pavilion. Through greenling land restoration, this project construction will not reduce the urban greenland, but also can increase the public green land volume after taken proper restore measures (such as parterre above the entrance/exit) and enhance the urban greening coverage rate. In addition, the construction of parking depot and repair depot will damage original agriculture vegetations and green lands, so the greenling design in combination of trees, shrubs and grass will be adopted for the ground buildings and surroundings and interior of fields after project construction so as to effectively restore the vegetation volume. Before engineering construction, submit to competent authority for approval according to related provisions in Regulations on Zhengzhou Urban Greening Management article 27, and obtain temporary greening land occupation permit and properly compensate the owner unit of greenland before occupation (the temporary green land occupation period must not exceed the construction period of the project, and it must be returned at due time and restored); during construction, it is necessary to strengthen the construction organization design and reduce the occupation amount and period of green land as possible; after construction, it must compensate and restore the damaged green land. The farmland surface cultivated soil in excavation sections shall be independently deposited during construction for later greening or ecological recovery. Nanyang Road is of the old city area and the trees along the street are mainly of old Chinese scholar tree; a number of sycamore trees with the breast diameter of more than 20cm at Chengdong Road and Zhengbian Road; although these street trees do not reach the protection specification for old and valuable trees, it remarkably improves the urban landscape. If it is confirmed to transplant these Chinese scholar trees or sycamore trees during station or ventilation pavilion construction, firstly consult with the expertise of related departments and prepare transplant program to ensure the survival rate. Following aspects shall be noticed during transplant: (1) Select proper time for transplantation of large tress. Once the engineering program determines the transplantation of trees, select the transplantation time as early as possible. (2) Take proper treatment measures and digging measures for large trees before transplantation, such as trimming of branches and wrapping of tree roots. (3) Select proper transport method and transplantation site for placement of the trees. The above aspects can ensure high survival rate of large tree transplantation. 287      Meanwhile, for the landscape damage due to tree transplantation during construction, it shall be recovered with proper greening trees such as camphor trees and Chinese scholar trees which are suitable for Zhengzhou local conditions so as to maintain the landscape coordination. (III) Species selection for urban greening trees According to site actual investigation, the main plants planted in the streets in Zhengzhou city include: Platanus orientalis, goldenrain tree, photinia serrulata, ligustrum vicaryi, dragon juniper, cedar, boxwood, small-leaf privet, large-leaf privet, Chinese scholar tree, Chinese Rose, southern magnolia, gingko, Ailanthus altissima, Sabina chinensis, aspen, silk tree, crape myrtle, flowering peach, Prunus cerasifera, pyracantha crenatoserrata, Cericis chinensis, hibiscus, nandiana, berberis thunbergi, clove tree, magnolia, photinia glabra, sweet osmanthus, cherry, pomegranatel, pittosporum. We has also investigated 10 roadside parks such as Lvchegn Squre; the main tree species planted include: prunus cerasifera, salix Salix x aureo-pendula, Chinese Rose, mahonia, Nandina, Chinese little leaf box, Cericis chinensis, southern magnolia, gingko, palm, Mount Huangshan, crape myrtle, berberis thunbergi, ligustrum vicaryi, Viburnum odoratissimum, pyracantha crenatoserrata, small leaf privet, large leaf privet, silk tree, loquat, sweet osmanthus, Juniperus formosana, black pine, five-leaved pine, juniper bush, photinia serrulata, dragon juniper, Chinese holly, Golden scholar tree, oleander, forsythia, Chinese juniper, oriental arborvitae, pittosporum, Sabina procumbens, Magnolia, sisal hemp, Sabina chinensis, Chinese pagoda tree, kerria japonica, Chinese scholar tree, weeping willow, bamboo, Sweet Olive. Above greening trees have favorable cultivation experiences and adaption. Except the allergic plants with willow blossoms and odors such as willow, others are recommended as the greening garden tree specs for this project. 5.6.2.4 Ecological impact analysis of water and soil loss By estimation, the quantity of earth work of car depot and parking depot, station and section is 4.974 million m3 in total, in which the excavation of 3.705m3 and back filling of 1.269 million m3. The line construction range is large with wide earthwork area and it will lead to severe water loss and soil erosion. In addition, most of rainfall in Zhengzhou city concentrates in June to September, which amounts 60% of annual precipitation, which provides the dynamical conditions for water loss and soil erosion. So the water loss and soil erosion issue during construction period must be emphasized. 288      Table 5.6-2 Balance sheet of project earthwork Excavation Fill Total earthwork Sub item (10,000m3) (10,000 m3) volume station 266.1 29.3 295.3 section 53.1 5.8 58.9 The parking lots 12.0 27.9 39.9 Car depot 39.3 63.8 103.2 total 370.5 126.9 497.4 Except the Jinshui Road Station adopts cover-excavation method construction, other stations in the line adopt open-cut method construction. The open-cut method not only damages the road surface and moves the underground pipelines, and also features wide construction working face and excavation area and large excavation earth volume, and requires backfill, so the water loss and soil erosion is severer than covered excavation method. The parking depot and repair depot are the construction sites with maximum area, and they require excavation and backfill during construction, so it will veritably lead to water loss and soil erosion. The water loss and soil erosion during construction not only affects the construction progress, but also imposes other environment impact. The silting and mud on road will suffer the pedestrian and traffic. The rain water with silt enters municipal rain pipe and ditch. The silt deposition may block the pipeline and ditches and impact the drainage capacity, and therefore further worsen the urban water ponding during rainy season. Based on above analysis, it is necessary to take measures to control and minimize the hazard during planning implementation process. The specific soil and water conservation measures include: prepare scientific and reasonable construction program, reduce the land occupation and vegetation destroy; reasonably determine the construction period and avoid the centralized construction in rainstorm season so as to prevent soil loss from water erosion, avoid construction in gale season so as to prevent soil loss from wind erosion; prepare adequate protection devices for rainstorm during construction period such as covering net, tarpaulin or grass mat to cover the rupture face of construction works, and properly fulfill the prevention and drainage works before rainy season so as to control the water loss and soil erosion as possible; during the excavation of surface soil for fill construction, the surface soil must be properly deposited and protected to avoid the spoil directly flushed by rainfall runoff into municipal rain or sewage pipeline and ditch; during construction period, to prevent the flushing and silt-up of project or other buildings and other facilities, the temporary drainage facilities shall be built to keep proper drainage conditions of construction site. The temporary drainage facilities shall combine with permanent drainage facilities so as to prevent silt-up, blockage and flushing; select proper enclosure structure type and internal support system, reduce excavation amount, timely remove the spoil and construction waste and determine the disposition of engineering waste slag; the spoil field shall be orderly and stably deposited with smooth drainage so as to prevent interference or damage of buildings near the spoil (slag) pile, drainage and other designs, and minimize the water loss and soil erosion; intensify the temporary greening of field, adopt native species, strictly control the construction excavation disturbance range, strengthen the survey and observation at outlet of drainage facilities, ensure cleaning and sprinkling of construction field and prevent the raise dust polluting the urban air environment; implement full process management of construction project, especially the water and 289      soil reservation monitoring during construction period; if required purchasing the sand, soil and stone materials during construction, it shall explicitly define the control responsibility of water loss and soil erosion incurred in purchase contract, and define that the unit prices of soil and stone materials have included related water loss and soil erosion control expense. In addition, it shall conduct application registration and clearing management according to related requirements in Regulations on Administration of Zhengzhou Urban Environment Sanitation and the solid waste treatment administration. 5.6.3 Analysis and protection measures of urban landscape environment impact The landscapes are divided into two levels of visual landscape and ecological landscape. The visual landscape refers to the observed general vision of ambient environment. The urban visual landscape refers to the combination of urban natural landscape, building landscape and culture landscape. The ecological landscape is the aggregation of different ecological systems, and made up from model lands, piece blocks and galleries. The urban ecological landscape refers to the spatial structures and appearance forms of all spatial range or urban layout of the city. The urban landscape is mainly restricted by the factors such as city features, urban development planning and surrounding environment characteristics. 5.6.3.1 Overview and present status of urban landscape along project line The areas for locations of parking depot and individual stations to be built in the project are of farmland and waste land, presenting the farmland ecological landscape; the regions passed by the line sections consist of city artificial buildings and road, presenting typical urban ecological landscape. The car depot area is mainly of forest ecology landscape. There are various function blocks such as dense residential area, commercial center, traffic hub, large scale public building, scientific and education unit and public facilities along the line, but the dense population and unsmooth ground road traffic gallery in the regions along the line severely restricts the mitigation of people stream, material flow, energy and information and therefore influences the stability of landscape ecological systems in regions along the line. According to field survey, there are dense buildings in Erqi Square Station, Shuncheng Street Station, East Street Station, Chengdong Road Station passed by phase I project line and they are located in visual sensitive area with high landscape requirements. The line of this project is laid in underground form, so the engineering factors for landscape impact are mainly of station entrance/exit and ventilation pavilion, and the landscape factors include the appearance, structure and coordination with entire contraction zone. 5.6.3.2 Impact analysis of engineering construction on urban ecological landscape The urban landscape consists of many ecological systems centered on mutual relationship of human and environment. The urban landscape ecological structure is fragile with low automatic adjustment capability, and highly depends on the input/output of ecologic flows such as material flow and energy flow to maintain the own stability. 290      The traffic gallery is the only way for urban ecological system energy flow, material flow, information flow and population flow. The smoothness of traffic gallery is the premise of completeness and smoothness of urban functions. After put into operation of this project, as artificial traffic gallery, the link effect of its traffic transportation combines the basic urban function piece blocks, including large amount of resident area, commercial area, traffic hub, large public building and science & education units, into a complete structure system, enhances the communication of various function blocks landscape in the regions along line, enables the smooth input and output operations of various ecological flow between function blocks along the line, so as to ensure effective operation of city, enhance the stability of urban landscape ecological system and ensure urban healthy development. Since the subway gallery passes under the ground in urban area, it minimizes the separation of various function blocks along the line and therefore will not increase the fragment of urban landscape; it has no cross interference with ground traffic galleries and features large traffic capacity, quick, comfort and on schedule so that it can attract large ground passenger flow and relive the ground road congestion while maintaining the smoothness of own gallery. The artificial galley construction not only considers the economic benefit of galley, but also the environment benefit of gallery so as to achieve harmonious urban landscape structure. The rail transit has the advantages of environment friendly, energy saving and high efficiency, so the project can reduce the damage to environment as possible while improving the along-line landscape stability and facilitating the along-line regional economical development. 5.6.3.3 Impact analysis of engineering construction on urban visual landscape The urban landscape ecology requires coordination of natural landscape, urban buildings, urban resource development, economical development and protection of ecological environment so as to ensure orderly development of city, solve the city ecological problems and form the virtuous cycle of urban ecological system. This landscape impact assessment will emphasize the coordination of project buildings such as subway ventilation pavilion and station entrance/exit with urban visual landscape. (1) Landscape impact analysis on car depot and the parking lots and main substation The current situation of the depot and parking lot are green lands and fruit farm etc.. See Figure 5.6-1 and 5.6-2 for the current situation. 291      Figure 5.6-1 Current Land Occupation by Construction of Parking Lot Figure 5.6-2 Current Land Occupation by Construction of car depot For the landscape design around car depot & integrated base and main substation, the greening shall give priority to local native plants and also the fruit trees, but favorable for evergreen and flower species, and dynamically combine the arbors, shrub, flowers and grassland with proper colors and pattern combination so as to form a beautiful seasonal landscape. (2) Landscape impact analysis at station entrance/exit and ventilation pavilion Based on the principles of unification of ecology landscape structures and functions, the structures and appearances of underground station entrance/exit shall be subject to the access functions of rail transit. From the view of urban landscape composition, the beautiful city shall have the clear and identifiable features, i.e. clear understanding of districts, roads and objects, and be easy for get awareness of the overview and features of city and make people ease without confusion. The station entrance/exit, for its small land use and building volume, is less attractive; however, the design of building type, mass, height and color of entrance/exit at sensitive section must be uniform with the old town landscape; in suburban area, the station is more attractive, but the overall landscape sensitivity is low, so the design has more extension scope and it is easy to achieve the coordination and unification with surrounding landscape environment. 292      The design of ventilation pavilion shall firstly consider the combination with existing or newly-built structures, and then the independent devices for different models so as to coordinate with surrounding buildings and ensure the unique scene of each station at same time; thus they can adorn the urban landscape and beautify the urban living environment, and make each entrance/exit, ventilation pavilion and cooling tower as a work of art of city. (The details refer to figure 5.6-3, 5.6-4) . Figure 5.6-3 Station entrance/exit landscape Figure 5.6-2 Station ventilation pavilion landscape The land areas in the locality of the stations(entrances, exits and ventilation pavilion) along the phase project of No. 3 line are mostly urban construction land. The design of this subway project station entrance/exit shall consider as much as possible the models, coordination with ambient environment, night time lighting and surrounding greening to keep uniform styles for its design structure and appearance so that it can enhance the urban impression for visual joy, but also provide convenience for access of local residents and the riding of rail transmit by visitors and business from other cities. For the design of entrances and ventilation pavilion of 10 stations including Weilai Avenue Station, Fengtainan Road Station, Zhongzhou Avenue Station, Tongtai Road Station, Huanghedong Road Station, Nongyedong Road Station, Zhongxing Road Station, Boxue Road Station, Hanghai East Road Station, it shall consider in principle their location of new district and economic development zone, which is an integrated modern new downtown and CBD of commercial, office, information and business functions, so their structures and appearances shall be uniform as possible; adopt blending landscape design handling principle to uniformly plan and construct with surrounding buildings and construct the ventilation pavilion station, pavilion and other 293      ground buildings together to meet the design requirements of local urban regions. For 5 stations in Zhengzhou old town area including Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station and Jinshui Road Station, there are dense buildings around the stations and the ground buildings appears crowded. The rail transit construction shall be considered together with Zhengzhou old town reconstruction planning and Nanyang Road expansion project; The along-line regions integrates the functions of resident, commercial, traffic connection, special mending and lacing, so the design of the stations and ventilation pavilions in this section shall be arranged in combination with surrounding buildings as possible, and it can consider the joint construction with existing ground buildings if conditions allow so as to ensure the coordination of station buildings with surrounding urban building landscape, reduce the impact of newly built facilities on ground landscape visual effect and make them open space presenting the urban style. For Erqi Square Station and Chengdong Road Station, since they are near national and provincial historic sites to be protected such as Memorial Tower for February 7th Strike, Zhengzhou Confucius Temple and Zhengzhou Shang Dynasty Relics and there are many modern buildings such as Hualian Shopping Center, Wanda Plaza and Zhengzhou Department Store, and also near 3 historic and cultural blocks of Shuyuan Street, Confucius Temple- Chenghuang Temple, Dehua Street-Datong Road, the design of entrance/exit and ventilation pavilion of these stations shall fully consider the actual conditions and adopt the combination design concept of blending method and hidden method to both reduce the impact of station entrance/exit and ventilation pavilion on ground landscape visual effect, and not lose the eye-catching state of station building so that it can maintain the open landscape space of Zhengzhou city and surrounding grandeur feeling, but also blend into the modern atmosphere. (3) Impact analysis on scenic spots around construction sites Since this project adopts shield method construction, the construction sites during construction mainly focus on the area near the station, the ambient environments of construction sites of Line 3 phase I project can be classified as following types. The details refer to table 5.6-3. Table 5.6-3 Environment in areas around engineering construction site No. Section name Present status of surrounding area environment Present as farmland ecologic system of mountains and Start point--Xinglongpu Road 1 hills; the whole section is planned as urban suitable Station construction land in new round of planning Xinglongpu Road Station Present as typical urban ecological system of communities 2 --Nongyedong Road Station and commercial office buildings Nongyedong Road Station Present as farmland, and this area is planned as economic 3 –Destination development zone in new round of planning. For the construction site in section from start point to Xinglongpu Road Station, the original surface is severely disturbed during excavation with the vegetation destroyed and naked soil (which is apt to water erosion), so it shall focus on the coordination with surrounding ecological functions and take measures such as planting turf besides removal and clearing of construction waste soil and leveling of construction site. 294      For the construction site in section from Xinglongpu Road Station to Nongyedong Road Station, it shall clear and restore the roads and municipal land occupied during construction period so as to restore the landscape. The measures to be taken mainly include: clear and remove the construction waste soil solid waste and building waste during construction period; restore the municipal lands such as roads occupied during construction period; plant proper urban greening vegetation and maintain original urban greening belt and forest coverage rate. For the construction sites from Nongyedong Road Station to destination, since this area is planned as urban public green land, it shall be planted with proper species of urban greening trees after construction to restore the ecologic landscape and comply with the urban general planning. 5.6.4 Summary The urban rail transit system is an important part of urban structure, and also the main space for urban public livings. It directly involves in the formation of urban appearance and style and the living and communication environment of citizens, and becomes the long term daily visual aesthetics object to provide aesthetics outlook and living experience for residents, and also the components of city culture. Zhengzhou is a famous historic city and also a modern city with enormous development potential so that the historic landscape protection in modernization construction is a critical issue to ensure sustainable development of Zhengzhou city. As the new buildings added into the environment, the arrangement of subway ventilation pavilion and entrance/exit shall fully consider the city features and land use pattern, comply with the urban general planning, focus on historic continuity and culture completeness, strengthen the protection of historic relics and landscapes and alternation and blending of the new and the old and ensure the coordination and unity of urban style, clear overall arrangement, complete special development sequences, coordinative body, color and texture treatment so as to establish the aesthetics feeling artificial landscape in coordination with the environment, set up the modern city image with rich culture intension and features of times and enable the station buildings be an integral part of ambient environment. 5.6.5 Conclusion and suggestion 5.6.5.1 Conclusion (1) The project does not involve any ecological sensitive area such as natural reserves, scenic spot and basic farmland conservation area. (2) After construction and operation of this project, it will enhance the connectivity of all function block landscapes along the line, keep the smooth input/out operation between the function blocks, ensure the high efficiency operation of city, enhance the stability of urban landscape ecological system and ensure the healthy development of city. (3) According to the landscape aesthetics analysis and analog survey analysis, if fully considered the unique historic city property of Zhengzhou city and land use pattern 295      and adopted the design with blending method and hidden method, it can keep the coordination of ground buildings such as station entrance/exit and ventilation pavilions with ambient environment. (4) The construction of rail transit has remarkable advantages in saving of land resource and energy, and in favor for integration and modification of Zhengzhou land resources, relief of regional land utilization pressure and improvement of land utilization efficiency. 5.6.5.2 Suggestion (1) The arrangement of ventilation pavilion and station entrance/exit of this project shall, in the principle of protecting traditional landscape and respecting the local features, focus on the harmony and unity between Zhengzhou ecological construction and modern landscape. Under the conditions of meeting the construction access and ventilation requirements, it shall strive to merge into the ambient urban functions and coordinate with ambient building styles and landscapes. It is possible to plant surrounding dense multiple-layer vegetation such as shrub and grass so as to enclose the hardness space of building into soft space with the mediation effect of vegetation and therefore integrate the building space of station entrance/exit with ambient environment, increase the landscape ecological function and create a harmonious ecological environment of human and nature. Especially the areas near Memorial Tower for February 7th Strike, Zhengzhou Confucius Temple, Zhengzhou Shang City Ruins, and 3 historic and cultural blocks of Shuyuan Street, Confucius Temple- Chenghuang Temple, Dehua Street-Datong Road, which have the Zhengzhou feature and represents the historic and cultural connotation of Zhengzhou, the design of entrance, ventilation pavilion and cooling tower shall ensure the integration with surrounding environment; the low rise type ventilation pavilion and the ground buildings integrated in ambient environment are preferably designed. (2) Properly fulfill the planning of permanent land use and temporary land use during project design phase so as to minimize the occupation of green land and the impact of rail engineering construction on along-line urban green land system. For the green land occupied by the project, the employer shall carefully execute various application and approval processes, organize the construction strictly according to approved the land use range, fulfill necessary recovery and compensation for occupied green lands and recovery their ecological functions as soon as possible. (3) The project shall strengthen the greening and ecological construction in yard during construction process, focus on the protection of ecological environment in this region, reasonably plan the land use along the line, reserve the greening land and intensify the greening design in full land use range. Protect the vegetation in the land acquisition and along-line range during construction period, minimize the damage of forest, grassland and scrub around the temporary land use and operation area. (4) For the construction site in the section from Zhengzhou west railway station to Longgang Station, it is necessary to, besides removal of construction waste soil and leveling of construction site, pay more attention to the consistent with surrounding ecological functions such as planting of turf. For construction site in the section between International Sports Center Station and Xinjia’an Station, restore occupied municipal land such as road during construction period; plant proper urban greening 296      vegetation and remain original urban greening belt and forest coverage rate. (5) During operation period, the car depot & integrated base and substation will be completely afforested and the greening tree category shall meets the requirements of coordination with ambient landscape, improvement of ecological balance, rehabilitation and optimization of along-line environment. The greening tree category shall be mainly of local indigenous plant so as to form stable community structure with surrounding plants and prevent the biological invasion and impact on the stability and biological diversity of regional ecological system. (6) The construction unit shall, in combination with Zhengzhou climate and according to the regional rainfall features, prepare the construction organization plan of earthwork and avoid large scale earthwork construction in rainy season; during earthwork construction, it is necessary to take necessary sole and water conversation measures and implement the road surface drainage works simultaneously so as to prevent the formation of runoff of surface during rainy season which may directly flush and lead to collapse of vertical excavation face or bottom ponding. The construction waste slag shall be timely removed and the subgrade face filled shall be timely compacted and properly protected; during construction in rainy season, it is necessary to ensure smooth drainage system at construction site. 5.7 Ambient air influence predictive assessment and measures of ambient air protection 5.7.1 Air pollution source 5.7.1.1 Air pollution source during construction period The air pollutant emission during construction period mainly comes from the raise dust generated by construction excavation, material placing, earthwork transport and construction materials such as yellow sand and cement, and fuel exhaust emitted by construction machinery and heavy transport vehicles during operation period. The main pollutants include raise dust, smoke, sulfur dioxide (SO2) and nitrogen oxides (NOX). 5.7.1.2 Air pollution source during operation period After completion of this project, the EMUs for train have no locomotive exhaust emission. The air pollutant emitted only includes a few exhaust gas emitted by the diesel locomotive for car depot & integrated base, which is of mobile source. The main pollutants include NO2, SO2 and flues, of which the exhaust pollutants emission is low with minor air environment impact The exhaust of underground station ventilation pavilion may lead to certain odor impact. The exhaust odor from ventilation pavilion during initial operation period may be large, which is mainly due to the volatilization of various harmful gases from composite materials and devices used by the subway project. As the time goes on, this 297      part of gas will gradually reduce, it is hard to feel the odor at the area more than 15m downwind from the exhaust pavilion. In addition, the analog survey indicates there is basically no odor feeling for the ventilation pavilion at sides of road. The passenger transport volume of rail transit is large and it can substitute for many ground road traffic after put into service and therefore significantly reduce the automobile exhaust pollutants emission. At initial phase, the reduction volumes of bus exhaust pollutants emissions of COand NOx are separately of 111.6 and 30.9t/a and these reductions will be more at short term and long term. The rail transit is more rapid and comfortable than the bus, and can reduce the bus exhaust pollutants emissions as well as inhalable particle concentration in air so that it benefits for the improvement of environment air quality in Zhengzhou city. 5.7.2 Predictive assessment 5.7.2.1 Air environment predictive assessment during construction period (1) Raise dust production mechanism The possible drift distance of dust particles under the effect of wind or handling and vehicle movement will be affected by the initial speed, particle diameter and atmosphere turbulence intensity; the theoretical drift distance is the function of particle diameter and average wind speed. In case of wind speed of 4 - 5m/s, the drift distance for the dust participle of about 100μm diameter is 7 - 9m; for the dust particles of 30 - 100μm, the drift distance may be up to hundreds meters according to atmosphere turbulence intensity; for the dust particles of less diameter, its drift distance will be ever further. The raise dust emission in construction site in positive relation to the ground dust quantity, flow of transport vehicles, traveling speed, deadweight and wind speed, i.e. the more the ground dust quantity, the higher the traveling speed, the larger the load, the higher the wind speed, and then the more the raise dust emission is.. During demolition of housing, various fine particles will form the raise dust under the demolition external forces, and the cleaning of construction site, deposition and transportation of building wastes will also lead to raise dust pollution. The raise dust quantity from housing demolition relates to the demolition method, protection measures (if any) and present climate conditions; The construction of ground stations and car depots of this project will veritably form many construction exposed surfaces. The construction exposed surfaces is very easy to produce raise dust under dry and windy climate conditions. In addition, the slag and spoil from this project construction are mainly of clay silt, which has large viscosity under high moisture and therefore is hard to produce raise dust. However, the fine soil layer with small diameter will form after the surface dried and the fine dust will drift into the air due to human activities such as handling, movement and vehicle traveling or when the wind speed reaches related startup value, and then form the raise dust. The raise dust generated during vehicle transportation mainly includes following three aspects: 298      The vehicle stirs the ground dust when driving in construction area and forms the raise dust; During loading and transport process of dregs and soils, if not tightly and properly covered, the dregs and soils may scatter on the road during high speed traveling and jolting and then form the raise dust after rolled by the vehicles. According to the analog survey for Zhengzhou dregs and soils transport vehicles, the average scattering amount of dregs and soils for each vehicle is more than 500g. When the transport vehicle travels out of construction site, the wheels and chassis normally will carry certain number of soils due to contact with the dregs and soils. The carrying soils will scatter on the road and therefore form the raise dust. According to the survey, the average soil carrying amount of each vehicle driving out of the site is more than 5000g. The soils of access roads mainly scatter on the road surface of 1.2m wide and 1200m away from the construction site. The average surface dust amount is 190.2g/m2 and it is 39 times of that of road surface not affected by the construction. If the construction dregs and soils are deposited at the road side with vehicle passing, the average surface dust amount is 319.3g/m2 and it is 67 times of that of road surface not affected by the construction. (2) Impact analysis Sine most of the construction sites are near the traffic roads, the construction machines and transport vehicles with the fuel as power source emit certain amount of exhaust near the construction site. Although the total amount of exhaust emission in the region increases, it will not impose remarkable impact on ambient air environment as long as to strengthen the servicing of devices and vehicles, ensure no emission of soot not completely combusted and strictly comply with the regulations on motor vehicles in Zhengzhou city. The excavation and drilling on dry ground surface may generate the fine dust; in addition, after the original vegetation is destroyed during construction period, the ground surface is exposed with water evaporated and forms the dry and loose particles, and it will generate the raise dust in case of large wind or backfilling. A part of fine dust floats in the air and the other part drifts to nearby ground and building surface with the wind. The fine dust pollution during construction has large harness. If the fine dust floating in the air is inhaled by the construction staff or surrounding residents, it will lead to various respiratory diseases, and may also heavily impact the healthy because the fine dust carries large amount of pathogenic bacteria; the flying fine dust will also reduce the visibility and may lead to traffic accident; the fine dust drifting on various buildings and tree leaves may impact the landscape. The impact duration of secondary raise dust from transport vehicle is the longest and the impact degree will significantly increase for the damage of road surface and mud explosion in construction site. It is predicted that the raise dust quantity depends on road surface dust deposition amount under constant vehicle speed and weight. The larger the dust deposition amount, the heavy the secondary raise dust. Since the transported construction materials in this project are mainly of underground deep spoil with certain humidity, so the raise dust generated by the construction transport 299      vehicles in this project will only influence the residents near the construction site, especially the residents in first row of buildings. 5.7.2.2 Air environment predictive assessment during operation period In combination with the features of this project, the subway train adopts electric traction without fuel exhaust emission. The air pollution source is mainly of the odors emitted from exhaust pavilion. So the ambient air impact assessment of this project is mainly for the impact of gas emission from subway exhaust pavilion on nearby resident living environment. (I) Main job contents The main job contents of ambient air impact assessment include: (1) Briefly analyze the impact of odor emission from underground station ventilation pavilion. (2) Predict and calculate the total air pollutant volume emitted by integrated base track cars. (3) Predict the reduction of automobile exhaust pollutants emission due to substation for bus traffic by rail transit after put into service. (II) Assessment method (1) With analog method, predict and briefly analyze the impact of odors emitted from ventilation pavilion on ambient environment; (2) Adopt pollutant emission factor method to calculate the pollutant emissions from integrated base shunting locomotive and reduction of automobile exhaust pollutants emission due to substation for bus traffic by rail transit after put into service (III) Environment impact analysis of odors emitted from ventilation pavilion (1) Cause analysis of ventilation pavilion exhaust odor The gas emitted from subway station exhaust pavilion, not exposed to sunlight for long term in underground station, will breed the mould in dark and damp environment and emit stale odor; the power system during vehicle operation will increase the ambient air temperature in underground space and the vehicle passing and access of passengers will bring in large amount of dust and therefore increase the dust content of air; the CO2 exhaled by the crowd will increase the CO2 concentration in air; the high voltage electric spark between vehicle pantograph and contact devices will generate ozone in the air; the sweat volatilization and various composite materials sued for internal decoration engineering of underground stations will also give out harmful gas, and so on. According to the odor survey of existing subway station exhaust pavilion in domestic, the stale odor is the main component of exhaust odor in underground station ventilation pavilion, even if at the initial operation phase. (2) Analog monitoring and analysis of emission from ventilation pavilion 300      A. Analog survey location Shanghai M8 line Xiangnan Road was built in 2007 and has been normally operated for more than one year till now. The vehicles is of type C car for EMUs with variable voltage variable frequency regulation and control receiving the power from the catenary.; there are 263 pairs of trains at day time and 12 pairs in night time; there are an air supply duct and an exhaust duct separately arranged at ends of stations, and the station public area air treatment system is made up from the supply/exhaust duct in station and the air supply/exhaust fan in them, silencers and combination air valves so as to ensure the minimum fresh air operation in air conditioning reason in public areas, full fresh air conditioning operation and ventilation operation during non-air conditioning season. B. Monitoring overview a. Monitoring factor: according to exhaust characteristics of subway ventilation pavilion, determine the monitoring factors as follows: odor concentration, volatile gas (including 59 indexes such as Benzene) and particles. b. Monitoring time and frequency: in April 17th in 2009, Shanghai Environment Monitoring Center conducted related monitoring for the gas emitted from exhaust pavilion at Xizangnan Road station of Shanghai rail transit No.8 (M8) line. It took four times samplings and analysis for two factors of odor concentration and volatile gas at each measurement point, and conducted once monitoring for the particles, and also the synchronous meteorological observation. c. Layout of monitoring points: there are four monitoring points. 0# measurement point mainly reflects the source intensity and it is located in pipeline of ventilation pavilion; 1# and 2# points mainly reflect the attenuation rules after emitted into the environment and are located at downwind 2m and 10m from the outlet; 3 position is close to the road and mainly reflects the environment background conditions. Take the samples simultaneously at 4 monitoring points and the specific positions of monitoring points are as follows: 0# monitoring point: in internal pipeline of ventilation pavilion; 1# monitoring point: 2m down wind at outlet of ventilation pavilion; 2# monitoring point: 10m down wind at outlet of ventilation pavilion; 3 monitoring point: 15m down wind at outlet of ventilation pavilion; The specific positions of monitoring points are as follows: 301      Residential area  Xizangnan Road  Residential area  1# exit of line 4/8  Exhaust pavilion  Zhongshannan Road  Residential area    1# measurement point is located at 2m downwind from 1# exit exhaust pavilion; 2# measurement point is located at 10m downwind from 1# exit exhaust pavilion; 3 measurement point is located at 15m downwind from 1# exit exhaust pavilion; Figue 5.7-1 Schematic diagram of measurement points locations C. Monitoring result analysis Since the odor concentration and volatile gas have no related environment air quality standard, the monitoring makes reference to the monitoring concentration limits in GB16297-1996 “Integrated Emission Standard of Air Pollutants” and GB14554-93 “Emission standards for odor pollutants” for related analysis.

Brief analysis of monitoring results a. Volatile gas ○ a The monitoring results show the concentrations of 4 items in volatile gas with related standard (benzene, toluene, dimethylbenzene and chlorobenzene) are less than the concentration limits for secondary monitoring in “Integrated Emission Standard of Air Pollutants” (benzene of 0.40mg/m3, toluene of 2.4mg/m3, dimethylbenzene of 1.2mg/m3 and chlorobenzene of 0.40mg/m3); ○. The monitoring data indicate, the concentration of volatile gas materials emitted by b ventilation pavilion is basically equivalent to that of ambient environment, so it can consider that there is no pollution of this category of materials. b. Particle concentration ○ a The monitoring results show the concentration value of particles at each measurement point is lower than the secondary monitoring concentration limit requirement (1.0mg/m3) in GB16297-1996 “Integrated Emission Standard of Air Pollutants”; ○. The monitoring data indicate, the concentration of particle materials emitted by b ventilation pavilion is basically equivalent to that of ambient environment. Since the subway environment control system has complete dedusting system with certain vibration reduction effect for the particles of external environment, so it can consider there is no pollution of this category of materials. c. Odor concentration ○ a The monitoring results show the odor concentration at each monitoring point has exceeded the monitoring concentration reference limits in Emission standards for odor pollutants; ○. The monitoring data have no evident rule. In 4 groups of sample data, the odor b concentration in the internal pipeline of ventilation pavilion is slightly higher than that at downwind 15m from the outlet of ventilation pavilion. It means, after the ambient air enters the subway environment, the odor concentration in exhaust slightly increases due to human body odor and mildew smell in underground space; however, the data at downwind 2m and 10m from outlet of ventilation pavilion show that the subway exhaust pavilion is not the unique odor source for ambient air and the road traffic exhaust is also one of the sources; the proportion of odor concentration in gas emitted by subway exhaust pavilion is not high so that there is no evident attenuation rule in various groups of data. The survey of residents around Shanghai rail transit No.2 and No.8 lines, at initial phase after subway construction, there is strong odor feeling in downwind 0-10m range from exhaust pavilion and it has certain impact on residential environment. However, as the times go on , the exhaust odor of ventilation pavilion significantly reduces. The survey form indicates that there is odor threshold or no odor at downwind 10-15m from exhaust odor from Shanghai subway line 2 ventilation pavilion and the areas more than 15m away can not feel the ventilation pavilion odor. 304      In addition, the analog survey shows the odor is hardly sensed for the ventilation pavilion at road side (3) Impact analysis of exhaust odor of ventilation pavilion during operation period According to the station plan in feasibility study design, carry out field survey for ambient environment of all ventilation pavilions of the project, and finally determine there are environment sensitive spots at 14 ventilation pavilion areas in 13 stations and 50m range of 1 sectional ventilation pavilion 50m. The impact analysis results of subway exhaust pavilion exhaust odor on sensitive spots refer to table 5.7-4. 305      Table 5.7-4 extent of sensitive point affected by Wind Pavilion off-flavors Sensitive point Station Wind Pavilion location Distance (m) Sensitive point overview The degree of influence Note Name West Wind Pavilion： Northwest side of the Xinliu Road Each floor has 19 households, a total of 26 floors, a total 15m away，not affected The wind pavilion intersection of Sanqun Road and Building 1 of Yuhua ninth city 30 Station of about 494 households facing backs sensitive point Changxing Road North wind Pavilion：North side of Hualian family member courtyard’s, 15m away，not affected The wind pavilion northwest exit, Shamen Road Station, west 19m a total of about 252 households facing Buildings 3, 4 and 5 backs sensitive point Shamen Road side of Changxing Road Station South wind Pavilion,：North side of Closer to the piston air pavilion, Cityorth Shore District, 1 # and The wind pavilion southwest exit, Shamen Road Station, west 19m a total of about 40 households facing with a slight impact at the initial 4#building backs sensitive point side of Changxing Road stage After the 1 # building is The 1 # building is an North wind Pavilion,：West side of City bus company, family member demolished by engineering, entrance and the 23 a total of about 42 households facing Xinglongpu Road Northwest exit, Xinglongpu Road Station courtyard , 1 # and 2# building Building 2# will be 23m from the location of the air Station wind pavilion, without effect pavilion.

In design, the car depot & the parking lots is equipped with 2 shunting locomotives (diesel locomotive for line inspection & repair and locomotive rescue). The shunting locomotive emits small amount of exhaust pollutants. According to emission coefficient method, the emission prediction of exhaust pollutants for Hongjiaozhou car depot & the parking lots shunting locomotive refer to table 5.7-5. Table 5.7-5 Prediction results of pollutant emission from car depot & the parking lots shunting locomotive Unit Diesel consumption Flue SO2 NOX kg/d 140 2.12 0.44 2.66 t/a 51 0.78 0.16 0.98 The car depot & the parking lots shunting diesel locomotive is of mobile source with small amount of exhaust pollutant emission and therefore minor impact on ambient environment air. (V) Reduction of automobile exhaust pollutant emission from substitution for bus transport The rail transit construction can relieve the traffic congestion of Zhengzhou urban road transport. The rail transit transport reduces the ground traffic vehicles and therefore the pollution of vehicle exhausts on urban environment air, and benefits for the improvement of urban ambient air quality conditions. After put into service of rail transit, it can effectively reduce the exhaust emission. Taken the bus for example, calculate with the average of 35 persons transported in an hour for each bus, covert the rail transmit traffic volume into bus vehicle quantity, and then figure out the automobile exhaust pollutant emission reduction from substitution for bus traffic by the rail transit according to daily turnover volume (see table 5.7-6). Refer to table 5.7-7. Table 5.7-6 Passenger flow prediction of Zhengzhou subway line 3 Daily total passenger Average Passenger traffic Peak high profile transport traveling design period intensity (10,000 volume （10,000 persons/h） distance persons/km) (10,000 (km) persons/km) （2023） initial stag 42.38 1.35 2.23 7.94 Short term 86.92 2.77 2.90 6.79 （2030） Long term （2045） 117.47 3.75 4.05 6.96 308      Table 5.7-7 Automobile exhaust pollutant emission reduction from substitution for bus traffic by the rail transit rail transit Automobile exhaust pollutant emission reduction from substitution for Pollutant Unit bus traffic Initial phase Short term Long term kg/d 305.7 521.1 352.7 CO t/a 111.6 190.2 128.7 kg/d 84.8 124.2 117.5 NOX t/a 30.9 45.3 42.9 As shown in table 5.7-7, after operation of rail transit, the Automobile exhaust pollutant emission reduction amounts of CO and CHX from substitution for bus traffic at initial phase are separately of 111.6 and 30.9t/a .and these reductions will be more at short term and long term. So the rail transit construction not only changes the traffic structures, increases the passenger transport volume, relieves the ground traffic congestion and more rapid and comfortable than bus, but also it reduces the exhaust pollution emission of bus transport and benefits the improvement of Zhengzhou urban environment air quality. The rail transit is one of effective approach to solve the urban traffic pollution. 5.7.3 Control measures for environment air pollution 5.7.3.1 Control measures for air environment pollution during construction period Most of the construction sites of this project are located in commercial area and other areas with dense residents, so they are sensitive to the raise dust. To this end, it is necessary to take practicable measures to control the dust generated during construction period of this project so as to control the dust pollution in construction sites and near the transport road along the line. (1) The employer and construction unit shall assign the persons in charge of raise dust control and determine their responsibility range. (2) The construction site shall set the hard enclosures of no less than 2.5m high; the main roads must be hardened and kept clean. Assign special person to be responsible for the cleaning works of construction site to timely sprinkle and clean to reduce the raise dust. (3) During demolition and excavation of dry soil surface, properly spray water and keep the operation surface at certain humidity. (4) The garbage and spoils shall be timely cleared (the wastes and spoils generated from housing demolition shall be completely cleared in 3 days after the demolition). The spoil deposits and bare soil for more than 2 days shall be covered with dust cloth or hardened to remove the dust. (5) When the air pollution index is higher than 100 or in case of dry climate with gale of grade 4 and above, prohibit explosion, demolition, earthwork and manual dry sweeping. When the air pollution index is between 80 and 100, clean once every 4h 309      and the sprinkling and wiping shall be alternatively conducted. When the air pollution index is larger than 100, the cleaning frequency shall intensify. (6) The office area and living area at construction site shall be afforested and rehabilitated. The water boiler and cooking stoves shall use clean fuel. (7) The vehicle transporting the garbage, spoil and sandstone must obtain the “Transport permit for spoil and sandstone vehicles”. (8) The earth-moving trucks shall be completely sealed without spillage. They loading shall ensure the materials will not scatter during transport. If any scattering, they shall be timely cleared to reduce pollution. (9) Set up the car washing platform at inside of construction site gate. The ground of car washing and access road must be hardened; frequently clean the muds on transport vehicles and chassis; clean the wheels or muds when the construction vehicles get out of the site so as to reduce the soil carried on the wheels. (10) Properly plan the traveling route and time for construction vehicles and avoid the traveling at crowded area and residential areas. For the areas with higher environment requirements, the transport shall be done at night time according to actual conditions so as to reduce the dust impact on the crowed. 5.7.3.2 Control measures of air environment pollution during operation period (I) Suggestion for control measures for odor impact of ventilation pavilion (1) It is proposed in the report that the buildings at the sensitive points within 10 meters to the ventilation pavilions shall be relocated; The positions of the ventilation pavilions within 15 meters to the sensitive point shall be adjusted. It can be guaranteed that the position of the ventilation pavilion can be 15 meters to the sensitive points after taking the measures. (2) To more effectively relieve the odor impact, plant ardors around the ventilation pavilions and set the air outlet opposite to sensitive spots. (3) The underground stations shall use the decoration materials complying with national environment standards, especially not use the materials containing PCBs, so that it can be in favor for protection of personal health and also relieve the impact of ventilation pavilion exhaust odor on ambient environment at initial operation phase. 5.7.4 Summary (1) In this design program, 8 sensitive spots at Dongfeng Road Station, Nongye Road Station, Huanghe Road Station and Shuncheng Street Station conflict with the land use of ventilation pavilion or the distance is less than 10m, and they are planned to be demolished; in addition, the distance from ventilation pavilions at Shuncheng Street Station and Taikang Road Station to the sensitive spot is less than 15m, and the odors emitted from ventilation pavilion will impact the resident livings to some extent; in combination with the control measures listed in noise topic, the environment 310      assessment suggests to adjust the locations of 8 ventilation pavilions with the distance of less than 15m from sensitive spots. To effectively relieve the odor impact, it is necessary to plant arbors around ventilation pavilion and make the outlet opposite to the sensitive spots such as residential building. The underground stations shall adopt decoration materials complying with national environment standard so that it can be in favor of protection of health of the crowd and also relieve the impact of ventilation pavilion exhaust odor during initial operation period on ambient environment. (2) After operation of rail transit, the reduction volumes of exhaust pollutants emissions of CO and NOX by the bus substituted by the subway at initial phase are separately of 111.6 and 30.9t/a and these reductions will be more at short term and long term. The rail transit is more rapid and comfortable than the bus, and can reduce the bus exhaust pollutants emissions as well as inhalable particle concentration in air so that it benefits for the improvement of environment air quality in Zhengzhou city. (3) The diesel locomotive employed is of mobile source with small exhaust pollutant emission and minor air environment impact integrated base. (4) The crowed buildings such as school, hospital and centralized residential house shall be not built in 15m range around the ventilation pavilion. (5) Since the rail transit adopts electric traction, there is no fuel exhaust emission during vehicle operation, and the impact of piston ventilation pavilion odor is slight at initial phase and no impact during operation period. 5.8 Electromagnetic impact predictive assessment and protection measures 5.8.1 Electromagnetic source The impact of this project on electromagnetic environment mainly includes: random ignition interference generated from the discharge gap due to poor contact between vibration or sliding plate and catenary when the EMUs travels on access line of vehicle integrated base; electromagnetic interference resulted from electromagnetic induction of substation due to high voltage or large current. The existing environment assessment indicates that the electromagnetic interference only imposes slight impact in certain distance with the civil television reception without any impact on human health. 5.8.2 Predictive assessment 5.8.2.1 Assessment job contents and job emphasis The impact assessment contents of electromagnetic environment include the impact of electromagnetic radiation generated from train operation on the resident television reception near ground section, car depot and specific repair section; impact of power 311      frequency electric and magnetic fields generated by main substation and the impact of radio interference generated on ambient electromagnetic environment. 5.8.2.2 Electromagnetic pollution source characteristics and impact assessment (I) Electromagnetic radiation generated by train traveling and impact (1) Characteristics of electromagnetic pollutant source generated by the train traveling Zhengzhou subway line 3 phase I adopts flexible overhead category for supply with the 1500V DC voltage and full compensation simple chain suspension. So it can adopt Guangzhou transit line 1 ground line electromagnetic radiation measurement as analog source intensity. Figure 5.8-1 provides the electromagnetic radiation frequency characteristics and distance characteristics of Guangzhou rail transit No.1. This figure is drafted according to the average value which will not be exceeded by 80% measurements at each frequency point and different distance. Guangzhou Urban Rail Transit Ground line  electromagnetic radiation  Background  Field intensity  Frequency (MHz)     Figure 5.8-1 Actual measurement results at different distances and frequencies of Guangzhou rail transit ground line The figure 5.8-1 shows out the variation trend of electromagnetic radiation intensity with the frequency and distance of measurement point to line distance when the rail transit trains pass. The electromagnetic radiations at 50MHz and 150MHz frequency points when vehicle passes are about 10dB higher than the background, while those at 490MHz at different distance points are close to the background. According to figure 5.8-1, table 5.8-1 provides the interference field strength values at different frequencies and distances. 312      Table 5.8-1 Interference field strengths of different frequencies and distances (dBμv/m) Frequency (MHz) 50 170 500 900 Distance (m) 10 32.7 31 19 17 20 27.9 34 17 15 40 2 31 15 14 (2) Prediction on Influences of Electromagnetic Pollution due to Train Operation: The No. 3 Zhengzhou subway line is totally underground line, and the electromagnetic interference caused by train operation will not influence the receptive effect of TV signals by surrounding residents. The train climbs up to the ground only at the depot and parking lot. However, there are no environmental sensitive points around the depots and parking lots, therefore the whole project of No. 3 line will not influence the signal receptive quality of surrounding residents. (II) Impact of electromagnetic radiation generated by main substation The impacts generated by subway main substation mainly include the interference by owner frequency electric field, magnetic field and radio, and the effect may be tested by analog with similar type of substations built and put into service. (1) Analog monitoring object and overview: The analog monitoring object is selected as Shanghai rail transit line 1 north extension “Lingshi Road main substation”. The substation is of 110kV ground substation for households with the high voltage incoming line of 110kV and low voltage outgoing line of 35kV and 10kV. All incoming lines and outgoing lines are laid with underground buried method, main transformers and other electric devices are built indoors. (2) Reference standard: DL/T988-2005 Methods of measurement of power frequency electric field and magnetic field from high voltage overhead power transmission lines and substation HJ/T24-1998 Technical regulations on environmental impact assessment of electromagnetic radiation produced by 500 kV ultrahigh voltage transmission and transfer power engineering GB7349-2002 Methods of measurement of radio interference from high voltage overhead power transmission lines and substations GB15707-1995 Limits of radio interference from AC high voltage overhead power transmission lines (3) Analog monitoring contents: 313      Power frequency electric field and power frequency magnetic field. (4) Instrument used: Adopt PMM8053A low-frequency electromagnetic field gauge for power frequency electromagnetic field measurement. All instruments are calibrated as qualified in RPC National Institute of Metrology. (5) Monitoring method: The PMM8053A low frequency electromagnetic measurement instrument is 1.5m from the ground surface. The power frequency electric field measures the vertical components and the power frequency induction strength measures the composite component of horizontal component and vertical component. The detailed measurement points and results are as follows: Substation fence  North  Fence of buildings in substation  3 m  35kV switch cabinet  110kVGIS switch cabinet  10kV switch  110kV incoming line  No.1 main  No.2 main  cabinet  substation substation Radio interference  measurement point    Figure 5.8-2 Distribution diagram for monitoring of Lingshi Road main substation Table 5.8-3 Monitoring results of power frequency electromagnetic field Vertical component of Power frequency magnetic Measurement power frequency Position description induction strength point No. electric field (μT) (V/m) south side high voltage 1 incoming line terminal fence 0.22 0.27 position 2 5m from measurement point 1 0.3 0.05 10m from measurement point 3 0.9 0.07 1 314      Fence at each side of 4 0.1 0.07 substation Fence at each side of 5 0.1 0.08 substation Fence at each side of 6 0.08 0.05 substation Fence at each side of 7 0.1 0.05 substation 8 5m from measurement point 7 0.09 0.02 According to above analog monitoring results, 110kV Lingshi Road main substation has a small electromagnetic leak because it is built indoors and the incoming and outgoing lines are laid underground. The maximum value of vertical component of power frequency electric field out of the fencing wall is 0.9V/m and the maximum power frequency magnetic induction intensity is 0.27μT, which are equivalent to the background value of normal regions and far lower than the recommended limit requirements of power frequency electric field intensity of 4kV/m and power frequency induction intensity of 100μT in HJ/T24-1998 Technical Regulations on Environmental Impact Assessment of Electromagnetic Radiation Produced by 500 kV Ultrahigh Voltage Transmission and Transfer Power Engineering. (III) Assessment conclusion According to analog prediction analysis, the monitoring points for TV at present status can receive 5 TV channels with normal antenna, in which 4 channels can meet the signal to noise rate of 35dB. After construction, under the impact of vehicle passing, only 2 channels can meet the signal to noise rate requirements. Since the cable TV network connection rate in teleview sensitive spots of this project is high, it is predicted that the radio interference generated by construction of this project will not generate obvious impact on teleview quality of nearby residents. There is no sensitive spot in 200m range of the car depot, testing line and parking depot of this project, so it has no impact on the teleview of nearby residents A main substation and a switching station are newly built in Zhengzhou subway 3 line. By analogy monitoring, after construction and put into service of Boxue Road main substation and Erqi Square switching station, the generated power frequency electric field and magnetic field comply with the limits of power frequency electric field of 4kV/m and power frequency magnetic field of 0.1mT recommended in HJ453-2008 Technical Guidelines for Environment Impact - Urban Rail Transit. 5.8.3 Electromagnetic pollution control measures 5.8.3.1 Measures for impact on television reception The CCTV facilities have been basically configured along the line of Zhengzhou subway Line 3 phase I project. The districts along the line have been uniformly installed with CCTV devices by the government with the wired TV network connection rate of more than 90%. Only a few rural residents do not have access to cabled TV due to economic reason, and watch TV with antenna. However, the whole No. 3 line is underground line, and has no influences on TV viewing by such rural residents. There are no sensitive points such as residents around the trial running line 315      of the depot at East Hanghai Road, thus no measures need be taken on such influence in the project. Recommend to intensify the routine maintenance on catenary so as to reduce the off-line rate and the electromagnetic disturbance during train operation. 5.8.3.2 Measures for impact on main substation According to survey of present status, the location of Boxue Road main substation currently is of a freight depot with logistics companies and warehouse and without any sensitive spot around; there is no sensitive facility such as high voltage line over the location. According to above analog analysis, although the power frequency electric field and magnetic field and radio interference generated by main substation complies with the national standard requirements, more and more persons begin to worry about that the electric and magnetic fields generated by the substation may impact the personal healthy with the social advance and strengthening of environmental protection consciousness, and then oppose the construction of substation close the residential area. The complaints of these issues have been the social hotspot. In the view of human orientation and establishment of harmonious society, to reduce the worrying of the public for electromagnetic impact and therefore the environment complaints due to electromagnetic radiations, recommend to reasonably lay out the main substation and properly plan the land around the main substation to keep the fencing wall of main substation away from residential area as possible, and the least distance from residential area shall be more than 50m. 5.9 Solid waste impact assessment and measures of disposal and protection 5.9.1 Solid waste pollution sources The solid wastes of this project during construction period mainly come from the spoil generated from stations and tunnel construction; the solid wastes during operation period mainly include the domestic garbage from station passengers and staff, solid waster from car depot & integrated base mechanical processing and maintenance works and staff domestic garbage, train passenger left wastes in depot, and small amount of domestic garbage discarded by the passenger, and waste oil and dregs from sewage treatment plant in car depot & integrated base, clothes wiping the oil in each procedures, waste transformer oil and EMUs battery regularly replaced. 5.9.2 Predictive assessment 5.9.2.1 Solid waste impact predictive assessment during construction period (I) solid waste properties 316      The solid wastes from this project mainly include engineering spoils, construction wastes and construction staff domestic garbage. The engineering spoils are mainly of the spoils generated from excavation and tunneling of stations and tunnels during construction process. The spoils generated from this project are mostly of clay silt with high viscosity in case of high moisture and less organic content. The construction staff domestic garbage is of normal domestic garbage, and the quantity is less. (II) Environment impact due to solid waste treatment The solid wastes produced during project construction, if not properly disposed, will obstruct traffic and pollute environment. During transport of spoils, if the vehicle is not properly cleaned, the muds and soils may scatter along the road and therefore pollute the streets and roads and impair the urban appearance; the traveling of spoils transport vehicles on urban roads will increase the vehicle flow in the regions along the line and may lead to traffic congestion. If the spoils are deposited and dumped randomly, it may lead that large amount of silts carrying the cement at construction site flushes into the nearby rain pipeline during rainstorm period and therefore the silting up of pipeline. The high turbidity sewage may lead to water loss and soil erosion if flowing into receiving river channel via rain pipeline, and it may also lead to seasonal ground water logging in rainstorm season near the construction sites. 5.9.2.2 Solid waste impact predictive assessment during operation period The solid wastes after subway operation mainly include: domestic garbage generated by station waiting passengers and working staff, of which the main components are of drink containers, paper towel, fruit skins, ticket remnant and dusts; wastes sweeping from the passenger car in car depot & integrated base, routine domestic garbage generated by production staff; waste battery generated by the vehicle. (I) Discharge amount of solid wastes and treatment conditions (1) Discharge amount of domestic garbage According to analog survey, the station passenger waste amount is about 50-100kg/d; the domestic garbage generated by the production and office personnel is calculated as 0.4kg/d per person, so the prediction of solid waste discharge amount of solid wastes after operation of rail transit is shown in table 5.9-1. 317      Table 5.9-1 Discharge amount of solid waste during operation period (initial phase) Source Discharge amount of domestic garbage (t/a) Production and office 165.7 personnel along the line Passenger 18.3-36.5(each) station garbage 384.3-766.5(entire line) total 568.3－968.7 As shown in table 5.9-1: the solid wastes generated after subway operation are of nontoxic domestic garbage and the total amount is 568.3-968.7t/a. The discharge amount is small and they are distributed in the stations, car depot & integrated base and other locations along the line. All wastes shall be collected and stored at specific locations and delivered to local environment sanitation department for uniform treatment. From this, the solid wastes generated after subway operations have minor environment impact on ambient environment. (2) Hazard solid waste disposal The hazardous solid wastes of this project are mainly of waste soil and slag generated in car depot & integrated base sewage treatment plant, clothes wiping the oil at each procedure, waste transformer oil and EMUs batteries regularly replaced, the domestic substation equipment has banned the use of PCB-containing compounds related material, the project will not produce the pollution caused by PCBs materials. The above hazardous waste shall be disposed by the agency with qualification for hazardous waste treatment. The assessment recommends that after line 3 puts into operation, Zhengzhou Rail Transit Co., Ltd. shall enter into agreement with the unit with qualification for hazardous waste treatment and deliver the hazardous wastes to them for treatment. The battery for EMUs is mainly of alkaline (Ni-Cd) battery. Each EMUs train has 2 battery banks and their service life is 36 months. All batteries are of maintenance free chargeable type. According to statistics, it is predicted that the vehicle integrated base will replace more than 1000 batteries every year on average. The replaced batteries are deposited in car depot and regularly treated by the manufacturers or agency with qualification for hazardous waste treatment (once – twice every year). So the batteries used by car depot and integrated base EMUs will not impose solid waste hazard on ambient environment. 5.9.3 Disposal measures 5.9.3.1 Disposal measures of construction period solid waste The solid wastes during construction period are normally of spoils generated during construction period. The total spoils quantity in stations and open cut sections of this project is 2.368 million m3, and total spoils quantity in shield section is 0.473 million m3; the car depot and parking depot are mainly of filling with the spoil quantity of about 0.513 million m3. The construction wastes in Zhengzhou are mainly disposed with landfill method. The landfill location is at the gullies in southwest hilly area. There are 4 planned construction building disposal locations at present, separately of Houzhai, Honghuasi, Xiaoliucun and Shawolicun. The basic conditions of all disposal fields are shown in table 5.9-2. 318      Table 5.9-2 Basic conditions of waste disposal fields during construction period of Zhengzhou rail transit 3 line Lan Present status d Capacity Approval use Land use Reclamatio Name (10,000m3 procedure area time limit n measures ) execution (Mu ) In Plant cherry 2011-202 Houzhai 60 137 transactio after filled 8 n up Plant In poplar, 2010-202 Honghuasi 40 80 transactio cherry and 5 n grape after filled up Plant apple, In 2012-202 cherry, Xiaoliucun 40 64 transactio 5 grape after n filled up In Plant fruit Shawolicu 2011-201 60 120 transactio trees after n 2 n filled up Total 200 401 / / / The total capacity of above 4 construction waste disposal fields is about 4 million m3, and can meet the demand for spoils from 3 line. However, if other spoil group is to be selected when 3 line construction commences due to the construction time sequence problems, it shall strictly comply with related requirements of Zhengzhou city to acquire the permit. The specific approval procedures are as follows: Approval Procedures for Construction Wastes Disposal in Zhengzhou City 1. Application The unit disposing the construction wastes on construction site in urban buildup area shall assign person (applicant) to urban management department of area under administration to get the application for approval of construction wastes disposal in Zhengzhou city and related certification data, and complete the form according to the requirements. The applicant shall provide the construction project planning permit of the planning competent authority. 2. Acceptance The urban administrative department of administrative service center in the area under administration registers and accept at the service window. 3. Initial review 319      The responsible person for initial review is responsible for the review of written materials, informing the applicant of related rights, conducting field survey and providing the initial comments to the section chief for review. 4. Review Carry out full review for the permit of this project; put forward the permit or refusal comment; submit to the supervised director for approval. 5. Approval The approval responsible person is responsible for the signature and approval of the decision, and issuance of urban construction waste disposal permit. By site survey, the 4 disposal fields are more than 4km away from the water sources, and currently of natural gully without water passing by, and with stable geological conditions. The assessment considers the location is proper. Since the locations suitable for landfill of mucks in Zhengzhou city are located in southwest gully area, while there are threw ate source protection zones of Changzhuang reservoir, Jianggang reservoir and south-to-north water diversion middle section main canal in this area, the assessment requires the construction unit to keep the spoil field away from the water source protection zone according to related requirements in Water Pollution Prevention and Control Law. The spoils generated from 3 line are planned to transport to above 5 spoil fields for disposal. Following environment protection measures shall be taken for transportation, and also the spoil deposition fields of construction sites and the spoil fields: Timely clear the generated dregs and spoils and maintain the environment tidy of construction site and surroundings; set up enclosures and bulletin board and harden the site entrance/exit according to related regulations; set up the vehicle washing and cleaning facilities complying with the requirements and assign full-time cleaner, and the vehicle in the construction site can drive out of the site only after cleaned by the washing and cleaning facilities; regularly sprinkle the construction site for dust falling and cover the exposed muds. Part of construction sections may generate liquidified shield soil, which shall be aired for some time at construction sit, and then cleared and transported with special vehicles; they shall be mixed with dry soils with certain proportion after transported to the disposal field before landfilling. The retaining wall shall be set on construction site to avoid the spoil flowing out during rainy season. 5.9.3.2 Solid waste disposal measures during operation period (1) The waste oil produced by oily waste water treatment system, oily rags of various working procedures, and waste transformer oil undergo harmless treatment by the organization with relevant qualifications. (2) The batteries regularly replaced in car depot are of hazard wastes, and shall be 320      reclaimed by manufacturers or qualified agency. The storage room of batteries shall be treated for anti-seepage to avoid percolation. (3) The sludge produced at the depots shall be collected, buried and disposed regularly by the domestic rubbish disposal plant located at Hongzhai Village in section 27. 5.9.4 Assessment summary (1) The solid wastes during construction period are normally of spoils generated during construction period. The total spoils quantity in stations and open cut sections of this project is 2.3680 million m3, and total spoils quantity in shield section is 473,000 m3, and the total spoils quantity of car depot is 513,000 m3. The spoils generated from line 3 are planned to transport to ERqi Qu and LongHu Zhen depot spoil field for excavation and backfilling treatment. (2) The solid wastes during operation period are mainly of station and car depot domestic garbage. According to analog survey data, it is predicted the total discharge amount of solid wastes during operation period of this project is 568.3 – 968.7t/a. The wastes at each station are collected by environment sanitation workers and collectively delivered to urban garbage treatment field for treatment, so there is only slight impact on environment. (3) The waste oil and dreg from sewage treatment plant in car depot & the parking lotsduring operation period, clothes wiping the oil in each procedures, waste transformer oil are of hazardous wastes, and shall be entrusted to the agency with related qualification for harmless treatment; the battery regularly replaced shall be reclaimed by the manufacturers and the anti-seepage treatment shall be conducted in battery deposition room to avoid leakage. So the soil wastes have little impact on ambient environment by the solid waster generated after operation of rail transit. (4) Explicitly prohibits the procurement of equipment containing polychlorinated biphenyls material in transformers and other equipment in the design and tender documents. 321      5.10 Social environment influence assessment and measures of social environment protection During construction period and operation period, the project construction will affect the people’s livings of Zhengzhou city to certain extent. The positive effects include: the project construction will provide Zhengzhou city people with a more quick, convenient and environment protection public transit facilities for ease of trip of residents; the adverse impacts include: during construction period, the fences will impose adverse impact on living and traffic of the people along the line, but the impact is temporary and controllable, and relieved by measures. So, the positive effects of construction of line 3 are far higher than the positive effect in long term. This chapter will consider the line direction and construction methods of subway line 3 project and the factors such as traffic organization and land utilization, present environment status and station design, and focus on the impact analysis on social environment by subway line 3 project from the positive and negative aspects. 5.10.1 Analysis of social environment impact 5.10.1.1 Positive effect This positive effects of this project on the society mainly concentrates in operation period, and mainly include following aspects: (1) Improvement of urban traffic after put-into-operation of rail transit 3 line; (2) Saving of land development along the line for the utilization of rail transit; (3) Vast business opportunity for the stores along the line from large passenger flow after put-into-operation of rail transit. (I) Impact on urban traffic after put-into-operation of rail transit 3 line is mainly laid along the urban main rods of Zhengzhou city. The line passes Changxing Road, Nanyang Road, Jiefang Road, East and West Street, Zhengbian Road and Shangdu Road successively. After put into operation of rail transit 3 line, After put into service of rail transit 3 line, due to its advantages of rapid, convenient and economic, it will attract large amount of passenger flow to share part of passenger flow on roads, and part of public routes may be replaced and another part of buses may reduce their departure frequencies so as to reduce the road pressure and fundamentally improve the traffic of above areas. Prepare reasonable bus-rail integral program to facilitate the public to use 3 line project, enhance the public traffic resource utilization rate of Zhengzhou city and finally improve the urban traffic of Zhengzhou city. (II) Impact of rail transit on land use variation along the line (1) Impact analysis of project land use on urban land utilization The total demolition area along project line is 10.2 hm2, permanent land use of 5.98hm2 and temporary land use of 30.08hm2. The temporary land use is temporarily 322      occupied during open cut construction method for underground stations. The expropriated collective lands are of vegetable plot, cultivated land, orchard and forest land at present. The expropriated state lands are of state construction land. In term of related passenger capacity, and in comparison to the ground traffic facilities, the rail transit features less land use area, larger transport capacity, higher speed and operation stability; the construction of rail transit can significantly saves the tense construction land use and is good for the saving development of land in Zhengzhou so as to save the valuable land sources for urban development of Zhengzhou. (2) Impact analysis of project on along-line land utilization The construction of 3 line project will speed up and promote the implementation of land utilization planning along the line, speed up the urbanization development process along the line. Under the induction effect of rail transit, the land utilization property of zones to be developed will substantially change. The main change is that the farmland and forest land are converted into resident land, commercial land and education land. The conditions of planning areas along 3 line are shown in figure 5.10-1. Figure 5.10-1 Conditions of planning zones along 3 line The rain transit 3 line passes through zone B3, zone A3, zone A7 (focus of Erqi 323      Commercial Center and Shang City Ruins), zone A8, Zhengzhou Comprehensive Transportation Hub core area and economic development zone. Hereby describe the impact 3 line construction on around land development by taking zone A2 as example: The planning range of zone A2 is shown in figure 5.10-2. The rail transit 3 line passes through the west of zone A2. It is currently of old town and mainly used for residence, railway and warehouse lands; and there are also many industry land. The land use proportions of four functions are separately of 26.63%, 20.24%, 10.67% and 8.67%. The public facility land use is dispersed and the public green land is seriously lack. The land uses in zone presents obvious sectional different with Huanghe Road as the boundary. The land block at south of Huanghe Road is well developed mainly of residence, education, scientific research and commercial lands, and the public service facilities and municipal facilities such as education and medicals are complete; while the land block at north of Huanghe Road is mainly for warehouse, village construction land and industry land, and few residence land, and the resident living and service facilities are seriously deficient Figure 5.10-2 Planning range of zone A2 After construction of rail transit 3 line, the planning control emphasis in this zone lies in: highlight the concept of city management, adjust the land use structure, optimize 324      the land use pattern, increase the tertiary land use, support the integration of land use and utilization with traffic (especially the land use around rail transit yard), coordinate the relations among along-line large buildings, municipal infrastructures and rail transit, analyze the adjustment objective and measures of road network, regular bus connection and pedestrian distribution system, specify the rail car depot and station land use control. The high strength and high mixture land uses can be developed around the station. Designate the compact district for building complex at large scale rail transit transfer center, encourage the construction of complex and further improve the human settlement environment. Figure 5.10-3 Planning map of zone A3 According to short-range planning of Zhengzhou rail transit, there are total lines of rail transit 1#, 3 and 5# lines pass through the planning zone. Total 7 stations are set in the planning zone, including 2 transfer stations. There are 3 BRT corridors planned in zone; at initial stage, the line passes through Nongye Road and a pair of bus stops are set at east of Nongye Road – Shakou Road overpass. A bus start/destination station is planned each at southeast of intersection of Jianshedong Road and Jingguangbei Road (8,100 m2) and northwest of intersection of Nongye Road and Shakou Road (2,500m2). There are 8 public parking depots in the section with the total area of 270,000 m2, separately located at southeast of intersection of Jianshedong Road and Xizhonghe Road, southeast of intersection of Jinshui Road and Jianxin Road, southeast of intersection of Shakou Road and Jinshui Road, northwest of intersection of Huanghe 325      Road and Shakou Road, northeast of intersection of Damengzhaibei Road and Shakou Road, northeast of intersection of Qunban Road and Shakou Road, south of intersection of Tiexi Road and Dongfeng Road, southwest of intersection of Xinglongpu Road and Shakou Road. The control detailed planning around stations of rail transit 3 line is in preparation, but has not completed. (3) Protection measures for impact of the project on land use The construction of 3 line project has positive and favorable effects on surrounding land utilization around 21 stations along the line, especially for Nanyang Road; with the construction of rail transit 3 line, Zhengzhou old town reconstruction plan and Nanyang Road expansion project, the land utilization and urban landscape along Nanyang Road will significantly change. When planning the land utilization functions in above areas, it shall consider together with the noise and vibration protection distance in this report for reasonable planning and therefore minimize the environment impact of project construction on existing residences and planned sensitive spots. The control detailed planning along 3 line will be adjusted according to social development requirements. Normally once every 5 years. In each adjustment, it shall be submitted for approval according to the procedures in Urban and Rural Planning Law and Zhengzhou Planning Management Regulations; the planning approved can be used for instruction of urban construction. The planning adjustment procedures are shown in the figure below. The detailed control procedures are shown in the figure below. 326      Submit the application materials (application report; boundary line of land and ownership certification, land transfer contract; planning reference drawing) Planning Bureau  Zhengzhou Application report Demonstration report Boundary line of land and ownership Demonstration review phase for certification, land transfer contract Planning reference drawing modification of design keynote passing Concept planning, demonstration Fail to  Questionnaire form for functional Passed department notice Application report Demonstration report Concept planning, demonstration  notice  Approval phase Planning reference drawing Boundary line of land and ownership certification, land transfer contract Modification keynote notice by Planning Bureau Questionnaire form for functional department    Figure 5.10-4 Control planning procedure for land utilization change 5.10.1.2 Negative Influences: The negative influences caused by the project on the society are mainly concentrated in the construction period as follows: (1) influence of enclosure during construction period on urban traffic; (2) influence of enclosure during construction period on resident income; (3) influence of enclosure during construction period on residents’ life. (4) Influences of underground vibration during construction period on stability of ground buildings. (I) Influences of Enclosure during Construction Period on Urban Traffic The major construction method for project section is shield tunnel method, and no influences will be caused on ground traffic. Except for Jinshui Road which adopts covered digging method, the other stations adopt open cut method, and influences will be caused on ground traffic during construction period. (1) Influences of Construction of No. 1 Line under Construction on Urban Traffic The project team surveyed the influences of station construction on ground traffic such as 27 square station, Tongbai Road Station, Minhang Road Station and Dongfeng 327      Road station etc. during project survey. See Table 5.10-1 for details. See Figure 5.10-5 for the traffic organization during construction period of 27 Square Station and Tongbai Road Station. (2) Influences of No. 2 Line Project on Urban Traffic See Table 5.10-2 for detailed influences of station construction of No. 3 line on ground traffic on the analogy of the influences of the stations built of No. 1 line on ground traffic. 328      Table 5.10-1 Traffic impact analysis of stations in construction of Zhengzhou rail transit 1and 2 line Road occupation Traffic for residences around the

and Chenyang Road Road Station opened 332      As shown in table 5.10-2, during construction of stations in Huiji District such as Xinliu Road Station and Shamen Road Station, although the open-cut method is used, the Huiji District Changxing Road is wide and the traffic flow is small, and the station construction only occupies part of road, so the residual road can still meet the traffic demand. In light of above facts, it has no remarkable impact on traffic. The Xinlongpu Station in Huiji District is on narrow Nanyang Road, but the Beihuan Road is wide with small traffic volume, and the construction does not occupy the narrow Nanyang Road, so it has little traffic impact. The stations in Nanyang Road including Dongfeng Road, Nongye Road and Huanghe Road Jinshui Road are in old town of Zhengzhou with dense population and seriously congested traffic at present. Except Jinshui Road Station, other stations adopt open-cut construction method, so it intensifies the congestion of Nanyang Road during construction period. The Taikang Road Station is located on current narrow Minggong Road with many buildings, dense population and complicated road conditions; it also connects with Zhengzhou Railway Station and commercial centers like Erqi Square with large visitor flows, so it is very congested. The Taikang Road Station adopts open-cut construction method and it has large traffic impact on Minggong Road during construction period. Erqi Square Station is a station in construction of 1# line. Through field survey, due to scientific traffic strike control for surrounding Zhengxing Street, Renmin Road, Erqi Road, Jiefang Road and West Street and the circular corridors in large shopping malls around Erqi Square Station for ease of pedestrian traveling, although this station construction adopts open-cut method, the construction enclosure is arranged at the triangular location of each intersection, and in combination with practical measures, it has little traffic impact during construction period. Jiefang Road and East and West Street are of Zhengzhou Commercial Center with dense human traffic and developed road network, the Shuncheng Street Station, East Street and Chengdong Road Station in this area may be affected during construction period; but the roads in this area is wider than Nanyang Road, so the impact is slightly less than that of Nanyang Road and Minggong Road. The Weilai Avenue Station, Fengtainan Road Station, Zhongzhou Avenue Station, Tongtai Road Station, Huanghedong Road Station, Nongyedong Road Station, Zhongxing Road Station and Boxue Road Station in Zhengdong New District are on the Zhengbian Road and Shangdu Road. This area is of new development area with 8 lanes road and 5m wide green belts between lanes and both sides of walkway; although it adopts open-cut construction method, the construction area is basically located in walkway and green belts, and the construction of stations basically do not occupy existing road, so it has little impact on ground traffic. By above analysis, in the stations with open-cut construction method, the traffic impact of Taikang Road Station by construction activities is the most serious, then followed by Dongfeng Road, Nongye Road and Huanghe Road Station on Nanyang Road Station. For Jinshui Road Station with cover-excavation construction method, due to current narrow road and large traffic volume, it can still ensure two-way 4 lanes traffic after adopting cover-excavation construction method; it has little traffic impact during 333      construction period. (II) Impact on resident incoming after enclosing during construction period The impacts of 3 line project on resident incoming mainly include: impact of part of farmland occupation at car depot, parking depot and access section of open cut on resident incoming; after open cut and semi-covered station, the resulted traffic blocking and cutoff will impact part of commercial tenants at both sides of open cut and semi-covered excavation station; the surrounding construction demolition around the station will affect the operation incoming of relocated merchants. (1) Impact on residents of farmland occupation According to field survey, the economic loss of residents due to land occupation of 3 line refers to table 5.10-3. Table 5.10-3 Expropriated collective land for parking depot and car depot Number of Number of Vegetable Arable Fruit Other Woodland Total Households People Field Land Garden Land Influenced Influenced I.

(2) Impact analysis on commercial tenants around the station by station construction During project survey, the project group surveys the impact on commercial operations by construction of Minhang Road Station of 1# line. The details refer to table 5.10-4. By analog with the survey of 1# line, the detailed economic loss of commercial units from station construction along 3 line refers to table 5.10-5. 334      Table 5.10-4 Commercial impact of Zhengzhou rail transit 1# line station construction Operation revenue Current road conditions Cause Station loss of store (%) Type of Position Name of store Scale construction Traffic store Current road method Traffic flow congestion width conditions Small open-cut At peak time, Relative Reduction of about No parking position;

The incomes of merchants around above stations will decrease 20%-30% in comparison to present status. For 260 merchants to be demolished along the line, compensate according to market price and provide 6 months close-down compensation reward. For 988 store employees, offer one-off 6 months minimum wage compensation for actual employees registered in business license. For other affected merchants, after 3 line operation, the passenger flow volume around the stations will considerably increase due to the radiation effect of rail transit and it will sustainably and long-term increase the above merchants’ incoming affected during construction period. As a result, although the income during construction period decreases, the construction period is far less than operation period and the incomes of merchants generally increase in integrated consideration of construction period and operation period. (III) Impact on resident livings during construction period The impact on resident livings by line 3 project mainly occurs during construction period. It includes the inconvenient traveling of residents or enterprise or public service units around the station during construction period and extension of traveling time for going to work and getting off work. The relocation and placement will affect the resident livings. At same time, the noise and vibration interference due to operation of construction machinery, deposition and transport construction raise dust, sewage, muddy water, construction wastes and construction materials during construction period will impact the resident livings. The main resident areas or enterprises or public service units affected along the line refer to able 5.10-6. 338      Table 5.10-6 Impact analysis of resident livings Name of residential area and Influence Influence Position Influenced factor organization period degree Xinliu Road noise, vibration, Construction Yuhua 9th City 1# Low Station traveling period Chengshi Bei’an Community 1# noise, vibration, Construction building traveling period noise, vibration, Construction Changxing Building traveling period Shamen Road Huiji District Changxing Road noise, vibration, Construction Large Station Subdistrict Office traveling period Changxing Road 2# Yard 13, 10# noise, vibration, Construction building traveling period Baiwen Garden 1#, 2#, 6#, 7# noise, vibration, Construction building traveling period noise, vibration, Zhengzhou Public Transportation Construction traveling, Company Family Area period demolition Xinglongpu Huarun Chengshi Zhiyin (Xinyu noise, vibration, Construction Large Road Station Yayuan) Community 1#, 5# building traveling period Construction Changjian Yufeng (in construction) Traveling period Sunshine Holiday Community 3# Building noise, vibration, Construction Large Sunshine Holiday Community 2# demolition period Building Tongle Community 46# building noise, vibration, Tongle Community 61# building Construction Dongfeng traveling, Large Food Machinery Plant Family Area period Road Station demolition 2# Building noise, vibration, Tongle Community North Area 1#, Construction traveling, Very large 2#, 3#, 4#, 5# building period demolition Futian Lijing Garden Community noise, vibration, Construction small 39#, 40# building traveling period noise, vibration, Construction Ronghua Family Area 3#, 4# Large traveling period Zhengzhou Ceramics Factory Family noise, vibration, Construction Area 1#, 3# building, Nanyang Road Large traveling period No.62 Nongye Road Nanyang Road 68# Yard Zhengtie Station noise, vibration, Construction Nanyang New Town Community 1#, Large traveling period 2#, 3#, 10#, 41# building noise, vibration, Xiaoyuzhai (Nanyang Road 266# Construction traveling, Large Yard) 3#, 5# building period demolition Nanyang Road the 1st Primary noise, vibration, Construction Large School traveling period noise, vibration, Zhengzhou Textile Machinery Staff Construction traveling, Large Huanghe Road Apartment 18# - 20# building period demolition Station Nanyang Road 296# Yard (Nanyang noise, vibration, Construction Moderate Renjia) 1#, 2#, 3# traveling period Nanyang Road 300# Yard 2# noise, vibration, Construction Large building traveling period 339      Zhengzhou Textile Machinery Co., noise, vibration, Construction Ltd.

(IV) Underground vibration impact on ground building stability during construction period Since the project adopts the construction methods of open cut and covered cut and shield method and auxiliary construction methods, the improper selection of construction methods will be liable to uneven settlement, ground collapse or uplift. It will impose certain impact on the stability of ground buildings along the line of project, and therefore the cracking or collapse of ground building along the project line. The list of ground buildings of which the stability may be affected due to engineering construction refers to table 5.10-7. 341      Table 5.10-7 Investigation of structures (buildings) along rail transit No.3 in Zhengzhou No. Name of road Pile No. Name of ownership unit Type of building Depth of foundation (pile Distance to the center line Construction area Important note foundation) 1 Nanyang road 右 K2+752-783 Xiaoji huimian Frame The depth of pile foundation is About 23.5m from the wast of the 2000 ㎡ 8.5m center line 2 K2+750-775 Nanyangzai dashaguo Brick concrete Natural foundation About 15m from the east of the 850 ㎡ center line 3 K2+776-822 Xinyu yayuan 3# Bottom frame + brick concrete The depth of pile foundation is About 22m from the east of the 4529 ㎡ 10.5m center line 4 K2+833-843 Xinyu yayuan 11# Brick concrete Natural foundation About 20m from the east of the 1048 ㎡ center line 5 右 K2+792-885 City bus company, family Brick concrete Depth of raft foundation 1.8m About 20m from the wast of the 1 号:3209 ㎡ member courtyard center line 2 号:3209 ㎡ 3 号:2915 ㎡ 4 号:2143 ㎡ 6 K2+879-923 Zhengzhou yanjing dashijie Bottom frame + brick concrete Natural foundation About 17m from the east of the 1800 ㎡ center line 7 右 K2+899-922 Zhengzhoukaoya Brick concrete No data About 25m from the east of the 578 ㎡ center line 8 K3+43-60 Henan zhubao, family member Brick concrete No data About 18m from the east of the 1454 ㎡ courtyard center line 9 K3+70-121 Zhongji urban spring Frame The depth of pile foundation is 16m About 31m from the east of the 19904 ㎡ center line 10 右 K3+178-312 Grain transport community, 3 #,5 3#、5#：Brick concrete 10#： Natural foundation About 20m from the east of the 3 号楼：1999 ㎡ # ,10#Building Frame center line 5 号楼：1769 ㎡ 10 号楼 3680 ㎡ 11 Nanyang road K3+175-191 Building No.2 and No.7 of Frame The depth of pile foundation is 14m About 35m from the east of the 2 号：7828 ㎡ K3+231-249 City-state of Jianye Yihao center line 7 号：7972 ㎡ 12 K3+271-313 Office building Brick concrete Natural foundation About 18m from the east of the 2600 ㎡ center line 13 K3+335-395 Yard No.149 of Family Brick concrete Natural foundation About 16m from the east of the 2842 ㎡ residential building of Zhengzhou center line Tractor Plant 14 K3+400-460 Family residential building of Brick concrete Natural foundation About 18m from the east of the 1706 ㎡ K3+470-530 Zhengzhou Tractor Plant center line 15 K3+610-622 Tianxiu Homeland Bottom frame + brick concrete Natural foundation About 42m from the east of the 20000 ㎡ center line 16 K3+558-588 Liuzhai Office Building of Huiji Frame The depth of pile foundation is About 21m from the east of the 2767 ㎡ District 12.5m center line 342      No. Name of road Pile No. Name of ownership unit Type of building Depth of foundation (pile Distance to the center line Construction area Important note foundation) 17 右 K3+597-607 Family residential building of Brick concrete No data About 19m from the wast of the 8276.52 ㎡ Huiji District Education Office center line 18 右 K3+615-750 Building No.1 and No.2 of Yuhua Brick concrete Natural foundation About 24m from the wast of the 共 36566 ㎡ Wenhui center line 19 K3+722-769 Dongfang Hospital Bottom frame + brick concrete No data About 24m from the east of the 14700 ㎡ center line 20 K3+770-876 Bojin Shopping Mall Frame The depth of pile foundation is 12m About 17m from the east of the 39000 ㎡ center line 21 Nanyang road K3+900-934 Office building of Nanyang Road Frame The depth of pile foundation is 13m About 30m from the east of the 4072 ㎡ Sub-branch of ICBC center line 22 右 K3+898- 右 Building No.1, No.2, No.3, and Frame Natural foundation About 22m from the wast of the 1 号楼： 5631 ㎡ 2 号楼：5308 K4+30 No.4 of Yuhua Wenqing center line ㎡ 3 号楼：5755 ㎡ 4 号楼： Community 5643 ㎡ 23 K4+38-158 Frontage shop of Liuzhai Vallage Brick concrete No data About 16m from the east of the 371 ㎡+1526 ㎡ center line 24 右 K4+49-59 Family residential building of Brick concrete No data About 24m from the east of the 1969 ㎡ Zhengzhou Brewery center line 25 右 K4+181-191 Family residential building of No data No data About 25m from the wast of the 10128 ㎡ Zhengzhou Brewery center line 26 K4+223-241 Nanyang Road sub-branch of Frame The depth of pile foundation is 20m About 23m from the east of the 4400 ㎡ Zhengzhou Branch of Unicom center line 27 右 K4+211-260 Chuangye homeland No data No data About 22m from the east of the 5773 ㎡ center line 28 K4+252-272 Business office of Nanyang Road Brick concrete No data About 22m from the east of the 1500 ㎡ center line 29 右 K4+275-355 Commercial residential building No data Natural foundation About 26m from the wast of the 6453 ㎡ center line 30 右 K4+361-392 Zhengzhou Songtao Hotel Co.

The construction in the fourth phase has two sites, there are two entrances and exits at the north, and the construction site will be occupied for 4 months.   Fig.5.10-8 Traffic organization and construction fencing of the first phase on Weilai Road   Fig.5.10-9 Traffic organization and construction fencing of the Secondphase on Weilai Road 367        Fig.5.10-10 Traffic organization and construction fencing of the Third phase on Weilai Road   Fig.5.10-11 Traffic organization and construction fencing of the Fourth phase on Weilai Road Severe impact section: The current road is narrow, the traffic flow is large, there are 368      a lot of pipelines, and the surrounding demolition is difficult. Treatment measures: cover construction at sections crossing the intersection and fully fencing open-cut construction for stations at both sides, necessary demolition at the same time, traffic limitation, keep one driveway and one non-motor vehicle lane at either direction, and regional traffic organization. The treatment measures of this type of station are explained by taking Dongfeng Road Station as the example. Dongfeng Road Station is located at the intersection between Dongfeng Road and Nanyang Road. It is arranged in the south-north direction along Nanyang Road. It is a station with two underground floors. The entrance and exit are located at both sides of Nanyang Road. Nanyang Road is an important traffic artery in the south-north direction connecting the old town of Zhengzhou. The traffic on this road is heavy. Dongfeng Road is the important traffic corridor in the east-west direction connecting the old town and the eastern area. It extends to the east new zone at the east and to the high-tech zone at the west. The traffic volume at the surroundings is large. Currently, there are many passing bus routes. There are many bus routes overlapping with the rail transit. The northeast corner and southeast corner of this station is the mixed 6-storey residential buildings in Tongle community, the southwest corer is the 11-storey Futian high-rise and Futian Lijing Garden, and the northwest corner is the mixed 6-storey residential buildings in Jiari Huayuan housing estate. The east station has two underground floors. The main structure crossing the intersection is constructed by the cover excavation method. This station is located at the intersection between Dongfeng Road and Nanyang Road. The traffic is congested. The demolition of buildings in four quadrants is difficult. The construction of this station will be fenced in four phases. During the first phase construction, the crossroads of this station will be fenced, cover excavation method will be used, and traffic will be diverted to both sides of the fencing. During the construction period, the impact on traffic on Nanyang Road and Dongfeng Road, and this can basically meet the traffic organization requirements. Pipelines affected above the main structure will be relocated to the south and north of the cover plate. Vehicles have to pass round the edge of the fences, and the construction site will be occupied for 4 months. During the second phase construction, buildings in the place of accessory structures shall be demolished before construction. Nanyang Road at both sides of the crossroads will be fenced to construct the main structure at both sides of the station. Pipelines being affected will be relocated to the east and west of the station, and the construction site will be occupied for 12 months. The third phase construction has three sites, the entrance and exit and the wind pavilion at the east side will be fenced, and the construction site will be occupied for 5 months. During the fourth phase construction, the entrance and exit and the wind pavilion at the west side will be constructed, and the construction site will be occupied for 6 months. 369        Fig.5.10-12 Traffic organization and construction fencing of the first phase on Dongfeng Road   Fig.5.10-13 Traffic organization and construction fencing of the Second phase on Dongfeng Road 370        Fig.5.10-14 Traffic organization and construction fencing of the Tird phase on Dongfeng Road   Fig.5.10-14 Traffic organization and construction fencing of the Fourth phase on Dongfeng Road (2) Traffic organization measures in important sections The first phase of rail transit No.3 in Zhengzhou mainly travels under Nanyang Road, Minggong Road, Jiefang Road, and West Street-East Street. The ground transportation of these four roads is relatively congested.

The width of the standard section of the station is about 22m which will occupy most of the main road. Furthermore, there are many buildings at the surrounding. So the construction method of this station will be greatly affected. To guarantee smooth traffic, the cover excavation method will be adopted to the section crossing the intersection, and full fencing and open-cut will be adopted to both sides of the station. Meanwhile, necessary demolition is required. A driveway and a non-motor vehicle lane will be kept in each direction. Regional traffic organization will be conducted at the same time to guarantee smooth traffic. During the peak period, regional organization will be used to ease the traffic on the premise of station traffic organization in Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station and Jinshui Road Station. Minggong Road section Minggong Road is an urban trunk road and an important traffic artery connecting the new and old towns and Erqi business district in Zhengzhou in the south-north direction.

Weilai Avenue Wide road; the Station, Fengtainan lands occupied Road Station, by construction Zhongzhou Avenue Shangdu open-cut are mainly of 5 / Station, Tongtai Road method sidewalk and Road Station, road green Huanghedong Road land; it does no Station, occupy the 379      Nongyedong Road lane; no impact Station, Zhongxing during Road Station, construction Boxue Road period Station, Hanghai East Road Station As shown in table 5.10-10, during construction of stations in Huiji District including Xinliu Road Station, Shamen Road Station and Xinglongpu Road Station, since it has little impact on traffic, the measures taken mainly include reasonably arranging the station construction field and reducing the road occupation. For Dongfeng Road, Huanghe Road Station and Nongye Road Station using open-cut method construction in old town, since the traffic flow is large at present, the measures taken include properly arranging the construction field, enabling less or no road occupation and reducing the construction period; For Jinshui Road Station with cover-excavation construction method, it has little impact on the traffic; for Taikang Road Station, Shuncheng Street Road Station, East Street Station and Chengdong Road Station in downtown area, since the ground traffic flow is large and the road area occupied is large, the measures taken mainly include: preparation of traffic dispersion program to enable bypassing of vehicle in advance; elaborate arrangement of construction filed for less road occupation; setup of special lanes at both sides of field to reduce the traffic obstruction; speed up the construction progress and reduce the land occupation period; give priority to the smoothness of bus route. Among others, during the construction of stations along Nanyang Road with most serious traffic impact, recommend use of semi-cover-excavation construction method if conditions permit. For the impact on urban traffic by construction of Zhengzhou Rail Transit 3 Line, except preparation of reasonable traffic dispersion program, it shall set up real time notice to provide the enclosure information to the residents and it shall inform the residents in advance if any necessary bypassing. (IV) Ground and underground traffic integration program The network optimized adjustment methods of bus line along the track mainly include: newly built, cancel, adjust (including adjustment of direction, cut-down and extension, and adjustment of line orientation and functions such as change of bus model and timetable). The main conclusions of specific programs are described as follows. The connection methods of rail transit include: walk, conventional bus, bicycle, taxi, car and external traffic mode. At present, only the optimized adjustment principles and methods are put forward in feasible study phase. The detailed implementation program is to be deepened by public traffic planning and operation departments at next stage. The common methods include: Bus connection Realize the transfer of bus line and rail transit through the station; so the adjustment of stations, including bus start/destination station and midway bus stop are the key points to be considered for connection. The attentions for these two facilities at different areas are different. Under the conditions of well-developed bus route, the optimization of middle bus top is the concerned key point of connection; in peripheral areas, especially the terminal station, due to incomplete line, the connection of bus 380      passenger flow shall be handled by adding the bus start/destination stations and open up new conventional line or regional minibus. Bicycle connection The bicycle parking depot is the parking facility necessary for the bicycle passenger flow to transfer to the urban rain transit. Considered the climate, geographic features and traveling structure features in Zhengzhou, the setting scale of bicycle parking depot shall be reasonable with possible various methods. Car connection Similar to bicycle connection passenger flow, the car connection passenger flow has to depend on “P + R” Parking depot in connection; the land occupation for single car is large, so special layout of “P + R” Parking depot is mostly limited by land supply conditions; the common station, especially in central area, does not has the setting conditions. So the land supply capacity is the key factor to be considered for arrangement principle of “P+R” Parking depot. Taxi connection facilities The taxi connection passenger flow mainly enables the transfers with the rail transit through temporary bus stop and passenger waiting area. The land occupation of these two facilities are small and normally can be solved in road redline, so the dependency on supply is less than that of bicycle and car parking depot. 5.10.2.2 Protection measures for impact on urban resident incoming and livings (I) Mitigation measures for negative affects (1) For the economic loss of local farmer due to farmland occupation by car depot, parking depot and line route, it shall be compensated according to national and Zhengzhou municipal government compensation standard with the basic principle of not affecting the economic income of the farmers whose land is occupied. (2) Under the impact of station construction, the incomes of small-scale merchants around the stations such as Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station, Jinshui Road Station, Taikang Road Station, Shuncheng Street Station, East Street Station, Chengdong Road Station, Weilai Road Station and Zhongzhou Avenue Station during construction period decreases in different degrees. However, after put into operation of 3 line, the passenger flows around the stations will significantly increase due to the radiation effect of rail transit and it will sustainably and long-term increase the above merchants’ incoming affected during construction period. As a result, although the income during construction period decreases, the construction period is far less than operation period and the incomes of merchants generally increase in integrated consideration of construction period and operation period. For the merchants to be relocated and related employees for station construction, they shall be properly compensated according to national and Zhengzhou local standards in the relocation and placement process. The compensation shall base on the principle of not impairing the interest of merchants and related employees. 381      (3) For 260 merchants to be demolished along the line, compensate according to market price and provide 6 months close-down compensation reward. For 988 store employees, offer one-off 6 months minimum wage compensation for actual employees registered in business license. (4) For the construction of stations in old district with dense residents, enterprises and public service unit, it shall reduce the construction noise and vibration impact by setting up construction enclosure, properly arranging the machinery in construction site, prohibiting pile driving operation at night time, and relieve the impact of raise dust by sprinkling and dedusting in construction site and covering the construction materials. (5) Before construction, it is necessary to conduct various preparation works and detailed survey for the road and various underground pipelines such as power supply, communication, water supply and drainage pipeline involved in the line, coordinate with related department to determine the removal and relocation program in advance and fulfill various emergency preparation works so as not to impact the normal supply and operation of water, electricity, gas and communication facilities in the areas along the line and ensure the normal society livings. (6) The electricity and water consumption during construction period are large. The construction unit shall communicate with related department in advance to determine the pipeline and line connection programs, and properly connect the temporary pipeline and line. For the section with inadequate supply capacity, it shall modify the pipeline in advance so as to avoid temporary power cutoff and water cutoff or affecting normal water and power supply of regions nearby. (7) In addition, for other impacts on resident livings during construction period, it shall persuade the resident or shorten the enclosure and construction period as possible. It shall persuade the residents: After put into operation of 3 line, the passenger flows around the stations will significantly increase due to the radiation effect of rail transit and it will sustainably and long-term increase the small-scale merchants’ incoming affected during construction period. As a result, although the income during construction period decreases, the construction period is far less than operation period and the incomes of merchants generally increase in integrated consideration of construction period and operation period. (II)Improvement measures for positive effects (1) Design of station wheelchair access To ensure safe, convenient and rapid utilization of the traffic facilities by the people with various demands such as blind people, disabilities, office staff and the people with many luggage, Zhengzhou rail transit 3 line stations design the wheelchair access according to Code of Accessibility Design, such as sidewalk for the blind, accessible elevator and staircase, which can separately meet the requirements for the disables and the blind to ride the rail transit. The staircase provides a good luggage transport access for the people carrying many luggages. The design principle is to ensure minimize transfer line and save the traveling time of office staff. 382      (2) Consideration of proportion of men and women toilet positions According to related social survey and social feedback reports, due to different physiological characteristics of male and female, the time consumption in toilet for male and female has remarkable difference. According to the statistics, the average time consumption in toilet of male is only 1/5 of that of the female. Based on above reasons, improvement of toilet position design in 3 line stations to increase the toilet position numbers of the male and the female with the female toilet position increment larger than that for the male can reduce or avoid the lining-up for toilet of the female (the female toilet position increase will considerably shorten the lining-up time of the female) so that it can not only facilitate the female, but also enhance the satisfaction of the male waiting for the female. (3) Reasonable consideration of low-incoming group during determination of ticket fare In entire social group in Zhengzhou city, the low-incoming group is a special group accounting for a large portion. The definition of ticket fare for Zhengzhou rail transit 3 line shall consider the traffic of low-incoming group in Zhengzhou city. It shall prepare reasonable ticket fare satisfying most of people for different hierarchies and different incoming levels of low-incoming groups, and positively affect the society. 5.10.2.3 Protection measures for impact on ground building stability To avoid the cracking or collapse of ground buildings along the project line due to engineering construction, it shall properly fulfill all aspects of preparation and prevention works. First, the departments shall get familiar to the project conditions and record the possible affected buildings on ground along the project line, and take proper anti-vibration measures. The second, if any ground building cracking or collapse along the line during construction period occurs, it shall be immediately complaint or reported to related departments. The corresponding department shall provide the solution according to actual conditions in two weeks and ensure the normal livings of residents are not affected. 5.10.3 Assessment summary (I) Impact assessment of the project on social environment Whether in construction period or operation period, this project will affect the livings of Zhengzhou citizens in different degrees and from various aspects. The positive effects lie in that the project construction will provide Zhengzhou people a more rapid, convenient and environment protection public transit facility and Zhengzhou rail transit 3 line during operation period will become a more convenient, safe, comfortable and economic communication mean for the residents along the line; at same time, the project construction works and enclosure will inevitably bring forward adverse impact on the people along the line; however the adverse impact is controllable and temporary as long as implemented related relief measures in the report. 383      The positive effects mainly lies in: the rail transit construction improves the urban traffic to provide a more effective and low price choice for traveling of citizens; it brings forward favorable impact for change of land utilization along the line, promote the urbanization process, enhance the development strength along line; the construction of rail transit also significantly saves the traffic land use and provides valuable land sources for urban development of Zhengzhou The adverse impacts are mainly in construction period and include followings: the station enclosure impacts the local urban traffic; station construction enclosure imposes temporary impact on incoming of surrounding merchants; the construction enclosure leads to inconvenient livings of nearby residents and increases their traveling time; noise and vibration disturbance due to construction machinery operation, construction raise dust, sewage, muddy water, deposition and transport of construction garbage and construction materials will affect the living quality of residents; the ground settlement and vibration affect the ground building stability during construction period. (II) Protection measures for social environment impact by the project For the impact on traffic, take proper protection measures including traffic dispersion program, money compensation and mental compensation, and related report and complaint procedures. The specific protection measures for impact on urban traffic environment impact by the project are as follows: the traffic dispersion program for 3 line complies with the principle of “Compensate a road for each road Occupation”. The traffic pressure during the construction period can be reduced by taking the measures of fencing in different phases, regional traffic organization and necessary demolition.During construction of stations in Huiji District including Xinliu Road Station, Shamen Road Station and Xinglongpu Road Station, since the vehicle flow and passenger flow is small and the road is wide, the construction enclosure duration in traffic dispersion measures are short and the construction can be completed in short term. So its traffic impact is not much in long term. For Dongfeng Road Station, Nongye Road Station and Huanghe Road Station of Nanyang Road and Taikang Road Station of Minggong Road, the vehicle and passenger flows are dense and the roads are crowed. To avoid large impact of traffic by enclosure during construction period, the construction enclosure range in traffic dispersion measures are small and the enclosure duration is long. It is preferable to use cover-excavation construction method for Taikang Road. For the impact on urban traffic by construction of Zhengzhou Rail Transit 3 Line, except preparation of reasonable traffic dispersion program, it shall set up real time notice to provide the enclosure information to the residents and it shall inform the residents in advance if any necessary bypassing. (III) Protection measures for impact on urban resident incoming and livings by the project (1) Mitigation measures for negative effects For the economic loss of local farmer due to farmland occupation by car depot, parking depot and line route, it shall be compensated according to national and 384      Zhengzhou municipal government compensation standard with the basic principle of not affecting the economic income of the farmers whose land is occupied Under the impact of station construction, the incomes of small-scale merchants around the stations such as Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station, Jinshui Road Station, Taikang Road Station, Shuncheng Street Station, East Street Station, Chengdong Road Station, Weilai Road Station and Zhongzhou Avenue Station during construction period decreases in different degrees. However, after put into operation of 3 line, the passenger flows around the stations will significantly increase due to the radiation effect of rail transit and it will sustainably and long-term increase the above merchants’ incoming affected during construction period. As a result, although the income during construction period decreases, the construction period is far less than operation period and the incomes of merchants generally increase in integrated consideration of construction period and operation period. For the merchants to be relocated and related employees for station construction, they shall be properly compensated according to national and Zhengzhou local standards in the relocation and placement process. The compensation shall base on the principle of not impairing the interest of merchants and related employees. For 260 merchants to be demolished along the line, compensate according to market price and provide 6 months close-down compensation reward. For 988 store employees, offer one-off 6 months minimum wage compensation for actual employees registered in business license. For the construction of stations in old district with dense residents, enterprises and public service unit, it shall reduce the construction noise and vibration impact by setting up construction enclosure, properly arranging the machinery in construction site, prohibiting pile driving operation at night time, and relieve the impact of raise dust by sprinkling and dedusting in construction site and covering the construction materials. Before construction, it is necessary to conduct various preparation works and detailed survey for the road and various underground pipelines such as power supply, communication, water supply and drainage pipeline involved in the line, coordinate with related department to determine the removal and relocation program in advance and fulfill various emergency preparation works so as not to impact the normal supply and operation of water, electricity, gas and communication facilities in the areas along the line and ensure the normal society livings. The electricity and water consumption during construction period are large. The construction unit shall communicate with related department in advance to determine the pipeline and line connection programs, and properly connect the temporary pipeline and line. For the section with inadequate supply capacity, it shall modify the pipeline in advance so as to avoid temporary power cutoff and water cutoff or affecting normal water and power supply of regions nearby. In addition, for other impacts on resident livings during construction period, it shall persuade the resident or shorten the enclosure and construction period as possible. It shall persuade the residents: After put into operation of 3 line, the passenger flows 385      around the stations will significantly increase due to the radiation effect of rail transit and it will sustainably and long-term increase the small-scale merchants’ incoming affected during construction period. As a result, although the income during construction period decreases, the construction period is far less than operation period and the incomes of merchants generally increase in integrated consideration of construction period and operation period. (2) Boosting Measures for Positive Influences (I) Impact of station wheelchair access To ensure safe, convenient and rapid utilization of the traffic facilities by the people with various demands such as blind people, disabilities, office staff and the people with many luggage, Zhengzhou rail transit line 3 stations design the wheelchair access according to Code of Accessibility Design, such as sidewalk for the blind, accessible elevator and staircase, which can separately meet the requirements for the disables and the blind to ride the rail transit. The staircase provides a good luggage transport access for the people carrying many luggages. The design principle is to ensure minimize transfer line and save the traveling time of office staff. (II) Impact of increase of men and women toilet positions According to related social survey and social feedback reports, due to different physiological characteristics of male and female, the time consumption in toilet for male and female has remarkable difference. According to the statistics, the average time consumption in toilet of male is only 1/5 of that of the female. Based on above reasons, improvement of toilet position design in line 3 stations to increase the toilet position numbers of the male and the female with the female toilet position increment larger than that for the male can reduce or avoid the lining-up for toilet of the female (the female toilet position increase will considerably shorten the lining-up time of the female) so that it can not only facilitate the female, but also enhance the satisfaction of the male waiting for the female. (III) Impact of ticket fare rationality on low-incoming group In entire social group in Zhengzhou city, the low-incoming group is a special group accounting for a large portion. The definition of ticket fare for Zhengzhou rail transit line 3 shall consider the traffic of low-incoming group in Zhengzhou city. It shall prepare reasonable ticket fare satisfying most of people for different hierarchies and different incoming levels of low-incoming groups, and positively affect the society. (IV) Protection measures for impact on ground building stability Firstly, prepare detailed stability protection program for each buildings which may be affected by the project; secondly, fulfill the settlement observation and vibration speed monitoring for ground buildings along the line which may be affected by the project; in addition, if any ground building cracking or collapse along the line during construction period occurs, it shall be immediately complaint or reported to Tack Company. The Tack Company shall provide the solution according to actual conditions in two weeks and ensure the normal livings of residents are not affected. 386      5.11 Impact on physical culture resources and protection measures 5.11.1 Along-line cultural relics 5.11.1.1 Identification of along-line cultural relics The protection objectives of along-line cultural relics of this project are mainly of culture relics, old and valuable trees.

Construction control zone of Zhengzhou Shang Dynasty Relics The area within the Zhengzhou Shanghai Dynasty Wall (excluding the cultural relics protection range); the area of 200m from the boundary of self-protection range of Zhengzhou Shang Dynasty wall; copper smelting ruins and bone workshop ruins out of Shang City north area, i.e. the area at west of Huayuan Road, east of Jingwu Road, north of Jinshui Road and south of Weisan Road; Pottery Workshop ruins at west of Shangcheng west wall, i.e. the area in Zhengzhou 14th middle school; People’s Park tombs area, north Erqi Road tombs area and Zhangzhainan Street; bronze ware cellaring ruins, i.e. the area at south of 10m from north side of Longhai Road, east of Nancangxili, north of Nancang Street and west of provincial freight transport 1st company; cigarette plant tombs area, i.e. Zhengzhou Cigarettes Factory field (north of Xionger River, west of Zhengzhou Light Automobile Factory, north of Longhai Road and east of Yanchang street); Yangzhuang tombs area, i.e. the area at south of Fenghuan Road, east of Chengdong Road, west of Huozhanbei Street and north of Yangzhuangnan Street; the areas of 50m from both sides of Shang city outer wall, i.e. the areas going south from Fenghuangtai at southeast of Zhengzhou Shang City, till the municipal service company Xinzheng Road Family Area through provincial water conservation warehouse and then turning to northwest, through Zhengzhou 5th middle school, Buchang Street Huayuan Xincun, Yinji Shopping mall till Dongfanghong theatre, and the extension of outer wall ruins. Current protection status The Zhengzhou Shang City ruins and palace foundation site have not been effectively protected; for the entire wall, only the southeast wall is 8m higher than the ground and well protected; however, there are many temporary buildings on walls and surroundings due to historic reasons; most of these buildings or structures are in the cultural relics protection range such as Shang City wall body. Moreover, there are 389      related buildings in Zhengzhou Shang city construction control zone, of which the style does not agree to that of Shang City. Position relation with 3 line The section of Shuncheng Street Station to Tongtai Road Station of 3 line is fully located in the protection range of Zhengzhou Shang Dynasty Relics. The ruins are located underground, and separately of 31m and 6m from the left side and right side of southeast wall above the ground. The detailed position relation refers to figure 5.11-2.   Figure 5.11-2 Position relation of Zhengzhou Shang Dynasty Relics with rail transit (II) Zhengzhou Confucius Temple Zhengzhou Confucius Temple is located at north of Zhengzhou Guancheng District East Street and in former Zhengzhou Bearing Factory yard. The Confucius Temple is facing south. According to records in Republic of China Zheng County Annals, Zhengzhou Confucius Temple was built in Yongping Years of Donghan Dynasty Ming Emperor (in 58-75) with large scale. The original Lingxing Gate and Pan Pool are destroyed in “Cultural Revolution” period, and there are two buildings of Dacheng Hall and Ji Gate, and many wing rooms. In 2005, Zhengzhou People’s Government invested to rebuild and recover the Confucius Temple. The Recovered Confucius Temple land use is about 9.300 m2, and consists of Lingxing Gate, East and West Memorial Archway, Dacheng Gate, Minghuan Temple, Xixian Temple, Dacheng Hall, Zujing Pavilion, East and West Rooms and Stele Gallery. The Coloured Glaze art in Dacheng Hall can be called as the masterpiece in existing 390      historic building arts. On June 20 in 1963, Henan Province People’s Commission publicized the Confucius Temple as one of the first batch of Henan Province Cultural Relics Protection Units. (1)Protection range of Zhengzhou Confucius Temple The area 50m west from Xishan Wall of Dacheng Hall, 62m east from Dongshan Wall of Dacheng Hall, 116m south to Threshold Wall of Dacheng Hall to north boundary of East Street, and 100m north from Rear Eave Wall of Dacheng Hall. (2)Construction control zone of Zhengzhou Confucius Temple 100m north of protection range boundary; 100m east to protection range boundary; 120m west to protection range boundary to Zhigong Road; 100m south to protection range boundary. (3)Position relation with 3 line 3 line is not in the protection range of Zhengzhou Confucius Temple; the rail transit 3 line passes through Confucius Temple construction control zone in underground mode, but there is no ground building in construction building zone. The details refer to figure 5.11-3. Figure 5.11-3 Position relation of 3 line and Zhengzhou Confucius Temple (III) Memorial Tower for February 7th Strike February 7th Memorial Tower is located at south of Zhengzhou Center Erqi District Erqi Square. February 7th Memorial Tower was built in memory of Wang Shengyou and Si Wende, the railway strike worker leaders killed by Zhili Clique. In 1951, Zhengzhou People’s Government expanded the former site of Xiguan Changchun Bridge as Erqi Square with a hexagon wooden spire in the middle. In July 1 to September 29 in 1971, knock down the wooden spire and rebuild as reinforced concrete pentagon conjoined twin 391      towers; it was total 14 floors and 63m height, and a bright red five-pointed star is mounted on top of bell tower; the historic relics, figures, literal data and memorial articles for Jinghan Railway Worker Strike are displayed in the tower. February 7th Memorial Tower has been the symbol and logo of Zhengzhou. On Nov. 21 of 1986, Henan Province People’s Government publicized February 7th Memorial Tower as Henan Province Cultural Relics Protection Unit. On May 25 of 2006, State Council of People’s Republic of China publicized it as one of the 6th batch of national major cultural relics protection units. (1)Protection range of February 7th Memorial Tower 50m east from Tower east boundary to Asia Shopping Hall west wall; 46m west from Tower west boundary to Erqi Hotel east wall boundary; 95m south from Tower south gate to Youyi Commercial Building north door; 80m north from Tower north door vertically to left-east side of south door of Shangcheng Department Store. (2)Construction control zone of February 7th Memorial Tower 100m east from protection range boundary to South and North Xiejie; 70m west from protection range boundary to Erqi Hotel west street; 100m south from protection range to Yuanling Street, 80m north from protection range to Zhenghong Building north street. Execution of planning: February 7th Memorial Tower is located at urban center with high-rise building around, developed commercial environment, crowed traffic and large traffic volume. The vision corridor has been destroyed and the Zhengzhou landmark and symbol peculiarity have been seriously impaired. (3)Position relations with 3 line 3 line passes side through Memorial Tower for February 7th Strike underground; the line is within the protection range for Erqi Tower and it is only 3m from the tower body at the nearest part. Erqi Square Station is the transfer station of 1 and 3lines and there is no ground building such as entrance and ventilation pavilion; the entrance and ventilation pavilion are fully built in construction control zone. (IV) Penggong Temple Penggong Temple is located at east of Zhengzhou Erqi District Minggong Road north section, and in current People’s Park. It was built on October 10 in 1925 in memory of Peng Xiangqian, so it is called as “Penggong Temple”. Now the “Penggong Temple” only leaves a gate, 5 halls and 6 hexagon pavilions, and was included in People’s Park in 1957. On June 3 of 2009, Zhengzhou People’s Government publicized Penggong Temple as Municipal Cultural Relics Protection Unit; the protection range and construction control zone have not determined at present. The rail transit 3 line has not set the station at west gate of People’s Park and 3 track is about 79m from Penggong Temple. 392      (V) Other possible underground buried areas Zhengzhou Shang Dynasty Relics is of underground ruins. Besides it, the possible buried areas along 3 line include: ancient ruins distributed in high-tech industry development zone, ancient tombs and ancient cultural ruins distributed from Nanyang Road (Dashiqiao) to Henan Province Sports Center. The detailed positions refer to figure 5.11-4. Table 5.11-4 Schematic diagram of centralized areas for distribution of cultural relics for Zhengzhou rail transit network (VI) Old trees and famous wood species There is an ancient locust tree in Hugong Temple at south gate of People’s Park and 200m from 3line. 5.11.2 Impact analysis of along-line physical culture resources 5.11.2.1 Impact identification on along-line physical culture resources (1) Impact identification on cultural relics protection site during construction period The construction phase mainly includes the works of land acquisition which may lead to vanishing or damage of ruins body (above ground or underground), device transport, debugging and grooving; the pile foundation and shield construction activities may generate waste gas, electromagnetic radiation, flying dust, noise, construction garbage, vibration and collapse, damage of aquifer, and damage of buried cultural relics during tunneling of shield machine. (2) Impact identification on cultural relics protection units during operation period It will generate the impact such as waste gas, electromagnetic radiation, flying dust, noise and vibration during operation phase. The occurrence of construction project body will block off the vision corridor of cultural heritage, and therefore vanish or reduce the peculiarity and impose impact on ecologic landscape. 393      5.11. 2.2 Requirements proposed by Cultural Relics Protection Units for 3 line construction and execution (1) According to related regulations on construction control area of historic and culture sites to be protected in articles 18 and 19 in Law of the People’s Republic of China on the Protection of Cultural Relics, for the engineering construction involving construction control area, the engineering design plan shall be agreed by cultural relics administrative department and then submitted to urban construction planning department for approval according to regulations in law of cultural relics. (2) In the answer of State Administration of Cultural Heritage to route selection for Construction Project of Zhengzhou Urban Rail Transit: 1. This project shall be kept from the axis of memorial tower when passing underground of Zhengzhou Memorial Tower for February 7th Strike, and bypass from other foundation as possible. 2. The program shall include scientific and accurate project construction and operation, and vibration analysis report for Zhengzhou Shang Dynasty Relics (wall ruins) and Zhengzhou February 7th Strike Memorial Tower and necessary vibration reduction measures. 3. Henan Provincial Cultural Relic Bureau shall organize special archaeological excavation unit for archaeological investigation and exploration for the ground building areas to be built such as station and ventilation port of this project, and the incurred costs shall be assumed by the construction unit. 4. The stations and ventilation ports project newly built in construction control zone of Zhengzhou Memorial Tower for February 7th Strike shall be otherwise submitted for approval according to the procedures. The ground building construction projects involving Zhengzhou Shang Dynasty Relics shall be otherwise submitted for approval with related procedure according to the archaeological excavation results and management requirements for Zhengzhou Shang Dynasty Relics construction control zone after the archaeological excavation completed. (3) In the review comments of Ministry of Environment Protection for Report on Environment Impact of Zhengzhou Rail Transit Construction Planning (2013-2019), it proposes: 1. Increase the buried depth of line passing underground of Zhengzhou Shang Dynasty Relics and Zhengzhou Memorial Tower for February 7th Strike for 3 line phase I project, optimize the line position program near Zhengzhou Confucius Temple based on scientific verification an avoid adverse impact on environment sensitive objects. (4) Execution: 3 line bypasses the axis of Memorial Tower for February 7th Strike and there is no ground building such as entrance, ventilation pavilion and cooling tower in its protection range. The report for ground building in construction control zone to cultural relics management department is in transaction. There is no ground building in Shang Dynasty Ruins wall protection range; the archaeological exploration works for buried depth of Shang Dynasty ruins is in progress. 3 The protection range of Zhengzhou Confucius Temple has been bypassed during routing of 3 line and it passes through from its construction control zone range, so it meets the requirements in answer of Ministry of Environment Protection to line network planning environment assessment. 394      5.11.3 Cultural relics protection measures 5.11.3.1Memorial Tower for February 7th Strike (1) Protection requirements for Memorial Tower for February 7th Strike According to Protection Program for Zhengzhou Rail Transit Project Passing through side of February 7th Memorial Tower reviewed and approved in March of 2010, the Erqi Tower deformation control standards in construction period of short-term 1# line Erqi Square Station and long-term 3 line shield section are determined as follows: maximum settlement amount of foundation of no more than 20mm and the foundation inclination of no more than 0. 001. (2) Protection measures The protection program for Zhengzhou rail transit project passing through side of February 7th Memorial Tower consists of pre-reinforcement protection measures before construction and process control measures for 1# line station construction and 3 line shield section construction. The details are as follows: Arrange a row of 800mm-diameter bored piles along axis direction of 3 line, partly of broken line with the total length of 62m; the pile bottom is at 4m under 3 line shield tunnel and enters (33) silty clay layer (permeability coefficient of 0.08m/d); it will restrain the soil body deformation during 1# line pit foundation construction and isolate the ground settlement channel during 3 shield construction, as shown in figure5.11-5.   Figure 5.11-5 Protection program for Memorial Tower for February 7th Strike When the shield machine excavates to 50m position from February 7th Memorial Tower, strictly fulfill the shielding construction management, especially the management of shielding working level to ensure good conditions of equipment; adopt earth pressure balance mode; control the shield driving posture, excavated earth volume for each loop and synchronous grouting amount and carry out secondary grouting supplement and balanced excavation; carefully study the shield excavation parameters and optimize the parameters such as grouting mixing ratio, pressure, shield pushing force and speed according to special geology of Zhengzhou; ensure 395      smoothly and stably passing through side of February 7th Memorial Tower. Keep the ground settlement at minimum level and meet the requirements for ground cultural relics protection. The tracks in 50m range from protection range of February 7th Memorial Tower adopt steel spring floating slab to reduce the vibration impact on February 7th Memorial Tower during operation period. (3) Analysis of settlement monitoring of 1 line during construction period Carry out settlement monitoring at 1 line pit foundation construction phase; the monitoring results refer to table 5.11-2. It can be seen that the settlement values of each points of Erqi Tower are in the allowable range, so that it verifies that the protection measures for Erqi Tower is effective. 396      Table 5.11-2 Monitoring data for building settlement (Erqi Tower) of Erqi Square Station 1# line Construction period Number of The cumulative amount of change（mm） measuring itial value controlling value 3-1 Conclusion points 3-29 4-10 4-12 4-14 4-17 11-12 12-2 1-2 6-2 （mm） 5 JCJ-45 100.9782 0.0 0.2 0.1 0.2 -0.2 0.1 0.9 0.9 0.9 1.0 15mm Normal JCJ-46 100.9181 0.0 0.2 0.3 0.4 0.9 0.5 0.5 1.5 1.3 1.3 15mm Normal JCJ-47 101.2679 0.0 0.1 0.5 0.4 0.5 0.3 0.2 1.2 1.6 1.6 15mm Normal JCJ-48 101.1165 0.0 -0.5 -1.1 -1.8 -2.8 -3.0 -3.2 -3.2 -3.4 -3.3 15mm Normal JCJ-49 101.1266 0.0 1.4 1.9 2.4 2.5 2.2 2.2 2.1 2.1 2.2 15mm Normal   397      (4) Protection requirements for Erqi Square Station in this report Require the rail transit 3 line away from the axis of memorial tower and passing through from the outer side of tower foundation, and the depth shall meet the requirements of no less than 15 specified by cultural relics protection department. During construction, adopt underground diaphragm wall protection before exaction of underground station; intensity the protection near February 7th Memorial Tower. The tunnel construction adopts shield method; timely adjust the pressure during excavation to avoid displacement of tunnel. After construction of tunnel, the related government departments shall take strict limit measures to prohibit excavation of pit foundation with forced drainage method and heavily exploiting of underwater above the underground tunnel and 500m range at both sides so as to avoid instability of tunnel, and intensify the ground settlement monitoring near February 7th Memorial Tower. Thus the impact of rail transit project on cultural heritage during construction period will be minimized so as to fulfill maximum protection of cultural relics (body). The 3 station entrance is located at west side of Erqi Road and in front of Hualian Department Store and it is not in protection range of Erqi Tower. To avoid impact on Erqi Tower landscape, it is planned to adopt uncovered entrance. The design of this kind of entrance is very simple, i.e. no upper cover underground, and only mounting the safeguard fencing around the entrance with the height below 1.5m. The design of outdoor steps and handrails is kept uniform with the landscape of entire Erqi Square. There is no ventilation pavilion in protection range of February 7th Memorial Tower; the building styles of entrance and ventilation pavilion in its control zone shall keep uniform with February 7th Memorial Tower. Figure 5.11-6 Schematic diagram of coverless entrances 5.11.3.2 Zhengzhou Shang Dynasty Relics When rail 3 line passing under Shang City Ruins, it shall adopt steel spring floating slab ballast bed for vibration reduction. This rail system features favorable damping performance and can eliminate the solid sound. The natural vibration frequency can be very low (5-8Hz) with favorable vibration reduction performance. The maximum vibration reduction can be up to 20dB and it has remarkable vibration effect at low frequency range. The new construction, expansion and reconstruction are prohibited in key protection range, which must be approved by cultural relics department and the building height must be lower than 9m. the construction materials, colors, types, technologies and greening shall consider the coordination with ancient capital environment and related 398      protection planning for Zhengzhou Shang City Ruins. Furthermore, the depth of underground wall of Zhengzhou Shang City is about 8 to 13m according to the archaeological exploration, so recommend the subway buried depth as 15 to 20m. 5.11.3.3 Zhengzhou Confucius Temple The rail transit 3 line passes through underground of Confucius Temple protection range and it mainly impose impact on Confucius Temple Lingxing Gate (stone memorial gateway). Due to close straight line distance, according to provisions in Code for Industrial Vibration Proof for Historic Buildings, the culture relics protection site of masonry structure shall be kept 40m away from the line to meet the code requirements. The 3 line is about 82m from Lingxing Gate, so it is necessary to set steel spring floating slabs in 50m tracks at both sides of Confucius Temple protection range to reduce the vibration impact by 3 line during operation period. The nearby section of Zhengzhou Confucius Temple is passed through with shield construction method and the construction distance meets the construction safety requirements without need of any measures. 5.11.3.4 Penggong Temple The rail transit 3 line passes through under west gate of People’s Park and set a station (Jinshui River north side) at People’s Park northwest corner, i.e. the intersection of Jinshui Road and Nanyang Road (Minggong Road). The design of station, ventilation pavilion and cooling tower shall be coordinated with the Shang Dynasty Cultural Display zone of People’s Park and Jinshui River Waterfront Park landscape. 5.11.3.5 Protection measures for physical culture resources (I) Handling procedure of physical culture resources detected during construction period According to Law of the People’s Republic of China on the Protection of Cultural Relics (2002.10.28) Article 32 “In the course of construction of a project or agricultural production, all units and individuals that discover cultural relics shall keep the scene intact and immediately report to the local administrative department for cultural relics; after receiving the report, the department shall, except under special circumstances, rush to the scene within 24 hours and put forth its proposals on the handling of the matter within seven days. The administrative department for cultural relics may report to the local peoples government; requesting it to inform the public security organ of the matter and to seek its assistance in keeping the scene intact; and where important cultural relics are discovered, the matter shall immediately be reported to the administrative department for cultural relics under the State Council, which shall put forth its proposal on the handling of the matter within 15 days after receiving the report. The cultural relics discovered in such a manner as mentioned in the preceding paragraph belong to the State, and no unit or individual may plunder, privately divide or conceal them.” and Regulations on Protection of Cultural Relics in Henan Province Article 26 “In the course of construction of a project or agricultural production, all units and individuals that discover cultural relics shall keep the scene intact and immediately report to the local administrative department for cultural relics; after receiving the report, the department shall rush to the scene within 24 hours and 399      put forth its proposals on the handling of the matter within seven days. The administrative department for cultural relics may report to the local people’s government; requesting it to inform the public security organ of the matter and to seek its assistance in keeping the scene intact.” This practice code for environment protection puts forth following management requirements for the culture relics detected during construction period: of practice implementation: If the culture relics are found during construction period, it shall immediately stop the construction and keep the scene intact without conducting any action without authority, and immediately report to the local administrative department for cultural relics. After the administrative department for cultural relics puts forth the handling comments, the construction unit shall prepare the construction program of culture relics section according to the handling comments issued by culture relics department, and begin construction only after approved by culture relics department. Before archaeological excavation completes, no unit and individual may continue construction or conduct production activity in archaeological excavation area.

The impact of excavation of Foundation Pits at Subway #1 on Erqi Tower does not exceed the deformation limit. After reinforcement, the maximal settlement of Erqi Tower is 4.2mm, less than 20 mm and its foundation tilt is 0.0002. After reinforcement the impact of excavation of Foundation Pit #1 on Erqi Tower does not exceed the deformation limit. it is concluded that prior to reinforcement Erqi tower baseplate's maximal settlement is 10 mm and its tilt is 0.0003, and after reinforcement, they are 5 mm and 0.0002, respectively, none of them beyond the deformation limit. (2) Numerical Simulation Computation and Analysis on Impact of Shielding Tunneling of Subway #3 In the numerical analysis, a molar-Coulomb ideal elastic-plastic constitutive model is used for the earth body. = After calculation, prior to reinforcement Erqi tower baseplate's maximal settlement is -22 mm beyond the limit of 20 mm, its minimal settlement is -7 mm and its tilt is 0.0006 within the limit of 0.001; After reinforcement Erqi tower baseplate's maximal settlement is -15 mm within the limit of 20 mm, its minimal settlement is -8 mm and its local tilt is 0.0003 within the limit of 0.001. It is concluded from this that prior to reinforcement Erqi tower baseplate's maximal settlement is -22 mm and its tilt is 0.0006; After reinforcement Erqi tower baseplate's maximal settlement is -15 mm and its tilt is 0.0003, none of them exceeding the allowed maximal foundation settlement of 20mm and the maximal allowed tilt of 0.001. (3) Conclusion from comprehensive consideration of the impact of foundation pit construction at Subway #1 and shield tunneling at Subway #3 404      It is known from comprehensively assessing overall impact of foundation pit construction at Subway #1 and shield tunneling at Subway #3, i.e. superpose in linear way the above-described conclusions for impact of foundation pits at Subway #2 and shield tunneling at Subway #3 respectively, that after reinforcement Erqi Tower's maximal settlement is 19.2 mm within the limit of 20 mm and its foundation tilt is 0.0005, within the limit of 0.001. 23.6m  17.3m  23.7m  Raft  foundation   Fig.6.2-1 Profile relationship between the Memory Tower for “Feb. 7th” and the foundation pit of Line No.1 station and Line No.3 6.2.2 Analysis of Cumulative Impact during the Operation Period 6.2.2.1 Analysis of Cumulative Impact on Traffic during the Operation Period After the subway is put into operation, massive passengers will be attracted to travel by subways thanks to its quickness and convenience. Safety-related hidden hazards may be present at subway stations, especially at the transfer stations and those located at the down-town areas because the heavy passenger flow that concentrates around stations at the peak hours will cause temporary congestion or jam at some local stations and is hard to evacuate quickly in case of emergency. The subway, upon operation, will be connected seamlessly with the high-speed railway station, the train station and the long-distance bus station to form an integrated traffic network by connecting it with different public transport systems at proper positions including the public transport stops, BRT and the parking lots in order to divert passenger flow and save time and cost for passengers. 6.2.2.2 Analysis of Cumulative Impact of Noise during the Operation Period 405      During the operation period, if the noise sensitive point is located at the common range of wind pavilion and cooling tower corresponding to two transfer stations, the noise impact generated by the subway environmental control equipment will have cumulative impact. Concrete analysis is listed in table 6.2-1. Table 6.2-4 Cumulative impact on sensitive point by air-conditioning noise (unit: dB) Contribution value Cumulative noise Standard Name of Name of Current value of wind pavilion of value of Line No.3 value station sensitive point Line No.3 and other lines Day Night Day Night Day Night Day Night Building No.5 Huanghe in Huayuan 57.2 51.2 57.4 52.2 60.3 55.3 55 45 Road Community Station Building No.6 (Line in Huayuan 58.2 52.2 58.2 52.3 61.2 55.3 55 45 No.5) Community Various sensitive points will be affected by the noise of environmental control equipments for subway Line No.3 or Line No.5, and the noise values in day and at night are from 57.4 to 58.2 dB and from52.2 to 52.36dB, separately. Huanghe Road Station is a transfer station, and it also affected by the noise from environmental control equipments for subway Line No.3 and Line No.5. Therefore, the superposition noise value of various sensitive points in day and at night are from 60.3 to 61.2 dB and from 55.3 dB, separately. Compared with the corresponding standards, the noise at building No.6 in Huayuan Community and building No.5 in Huayuan Community exceeds the standard both in day and at night,. 6.2.2.3 Analysis of Cumulative Impact of Vibration during the Operation Period At transfer stations, the vibration caused by the increasing of passing times of subway will have cumulative impact on sensitive points on the ground. Cumulative analysis of environmental vibration generated by Xinliu Road Station, Huanghe Road Station, Seven Feb. Square Station, Dongdajie Station, Future Road Station, Zhongzhou Road Station and Zhongxing Road Station is listed in Table 6.2-2. 406      Table 6.2-2 Cumulative impact on sensitive points by environmental vibration (unit: dB) combined action of Line Combined Line No.3 alone Z10 No.3 and other lines Standard value Name Name of sensitive point action Remarks cumulative Z10 lines Day Night Day Night Day Night Xinliu Road Buildings No.1 to No.3 in 3, Line Line No.3 is 63.1 62.4 66.2 65.4 70 67 Station Yuhuang 9th City No.4 above Line No.4 First Primary School on 3, Line Line No.3 is 70.6 70.5 73.6 73.5 75 72 Nanyang Road No.5 above Line No.5 Buildings No.1, No.2 and Huanghe Road No.3 in No.296 yard on 68.9 68.7 71.9 71.7 75 72 Station Nanyang Road Building No.5 in Huayuan Community (No.300 69.9 69.4 72.9 72.4 75 72 Nanyang Road) Ziyanhuating Housing 67 66.5 70 69.5 75 72 Dongdajie Estate 3, Line Line No.3 is Station Yuhonghuayuan Housing No.2 above Line No.2 67 66 70 69 75 72 Estate 407      Various sensitive points are affected by the vibrations of subway Lines No.1, No.2, No.3, No.4 and No.5. The vibration values at day and night varies from 63.1 to 70.6dB and from 62.4to 70.5dB, separately. Transfer stations will also be affected by the vibration of other railways. Therefore, the superposition vibration values of various sensitive points at day and night vary from 66.2 to 72.9 dB and from 65.4 to 73.9 dB, separately. Compared with corresponding standards, the vibration values of buildings the First Primary School on Nanyang Road, and building No.5 in Huayuan Community (No.300 Nanyang Road) at night exceed the standard. 6.2.2.4 Analysis of Cumulative Impact by Air Pollution during the Operation Period The ambient air is mainly affected by the smell from the wind pavilion. The influence degree of peculiar smell is related to the ambient temperature, passenger flow volume and atmospheric diffusion conditions. Sensitive points which may be affected by cumulative air impact during the operation period are listed in table 6.2-3. Table 6.2-3 Cumulative impact of sensitive points by ambient air during the operation period Combined Accumulative result Standard Name of Name of action of (bad-smelling gas value Influence sensitive station wind concentration) degree point pavilion The distance from the wind Xinliu Yuhua 9th pavilion to the West wind Road City Housing <10 20 sensitive point pavilion Station Estate is long, so the cumulative impact is small Huanghe Southeast Zhengfangji Combined wind Road wind <10 20 Community pavilion and Station pavilion small Zhengzhou Southeast Dongdajie cumulative Post Office cooling <10  20  Station impact Building tower It can be seen from Table 6.2-3 that many transfer stations have the same wind pavilion. So the cumulative impact on sensitive point by wind pavilion is small. The distances from Yuhua 9th City Housing Estate near Xinliu Road Station to wind pavilions at both sides are small. They are separated by green land or road. So the cumulative impact by wind pavilion is small. 408      6.3 Mitigation Measures of Cumulative Impacts of this Project 6.3.1 Mitigation Measures of Cumulative Impacts during the Construction Period 6.3.1.1 Mitigation Measures for Cumulative Impact by Continuous Construction near the Memory Tower for “Feb. 7th” The protection scheme of the Memory Tower for “Feb. 7th” when the rail transit project of Zhengzhou side penetrating the tower includes pre-reinforced protective measure before construction and control measure during the shield construction of Line No.3. (1) Various enforceable reinforcing protection schemes are proposed in view of the deformation control standards, combining with similar successful engineering experience in China as well as the geological conditions of the Seven Feb. Square. And then, numerical simulation and finite element calculation are conducted for various schemes before reinforcement. On the premise of meeting the deformation requirements, the optimal scheme is proposed combining with economy, technology, pipeline modification and correction, and other factors. (2) A row of bored piles with the diameter of 800 mm are provided along the axis direction of Line No.3. The pile tops are connected into a whole by the 0.8m×1.0m crown beam. The pile bottom goes deep into 4 m below the shield tunnel of Line No.3, and enters into the (33) silty clay layer (permeability coefficient of 0.08m/d). Meanwhile, grouting pipes are embedded near the tower foundation. Information construction is adopted to the construction of foundation pit of Line No.1 and to the shield tunneling of Line No.3. Grouting reinforcement is prepared at any time according to the monitored deformation data. (3)The impact of foundation pit construction at Subway #1 and the reinforcement process on Erqi Tower will not be in excess of the deformation control limit because following factors have been considered in construction of the foundation pits: the water-retaining effect of the chemical churning piles outside the pits, the shear strength of the fending piles inside the pits and strength of the concrete support inside the pits to prevent water/mug ingress and water loss in formations, monitoring frequently data concerning uneven settlement of Erqi Tower in real time. The above-mentioned measured have been carried out during construction of Subway #1 and the data from monitoring has shown the requirement had been met. (4)Within 50 meters from Erqi Tower, the shield tunneling, especially the operation, will be under strict control to ensure equipment in good condition. The earth-pressing balance mode will be applied, the shield tunneling excavation position, earth cut from each cycle and the volume of synchronous grouting shall be under control, and secondary grouting will done to achieve tunneling in balance. The tunneling parameters of the shield tunneling machine will be studied in detail and parameters 409      such as grouting ratio, pressure, thrust force and speed of the machine will be optimized based on specific geologies in Zhengzhou to ensure the shield tunneling machine passes below Erqi Tower in continuous and steady way in order to achieve minimal ground settlement and meet the requirement on protection of historical relics. 6.3.2 Mitigation Measures of Cumulative Impact during the Operation Period 6.3.2.1 Measure to mitigate the accumulative impact on traffic 1. Based on the demand from traffic development, considering the land development mode along the subway route, the characteristics of connecting passenger flow, land condition, road network condition and the traffic condition, specific studies have been done on some topics concerning the integrated traffic plan in order to build a well-developed integration traffic network to meet the demand of resident traveling as quick as possible. Based on these results from studies, various station's accessing functions are defined and spatial arrangement of different types of connecting facilities are planned as a whole. There will be mainly five ways and means: (1) Pedestrian access Walk will be the final form for all accessing ways. The walk accessing system shall be first considered for all stations. A continuous, safe and comfortable pedestrian system shall be provided through squares, crossing-street facilities and foot paths based on the passenger flow to be accessed, considering road building and rebuilding. The barrier-free facilities shall be provided for and attached to the pedestrian system and be constructed together with the urban facilities. (2) Cycling access In view of the accessing features at difference areas along the subway route where most are residential areas, the cycling access is inevitable and planning of parking lots along the entire route shall be focused on whether it is convenient to access to residential areas. The accessing facilities shall be designed and distributed based on whether the land supply is possible and reasonable, and land will be reserved in view of the change in long/near term demand. The parking space will be reduced through parking space landscaping, sharing it with public buildings, three-dimensional parking, reducing space for a single cars. For the cycling accessing facilities, passengers will be encourage to use it more frequently. Specific bicycle parking space will be arranged to reduce the time percentage of bicycles using roads as much as possible. (3) Access to bus stops At the old urban areas where there are more public transports, the spatial position, the manners and the spatial size of the intermediate stops will be optimized by analyzing 410      the bus flow route, defining the main passenger flow direction and centering arrangement of the entrance and exit of railway transit. At other areas where the public transport is developing, public transports shall be planned and developed in consideration of the subway stations along its route. Bus stops shall be optimized and adjusted to proper positions while consideration shall be given to the intersections are coordinated as a whole to meet the requirement to connect subways efficiently. (4) Taxi access The regulations on design and arrangement of taxi facilities shall be complied and road and general traffic conditions at different areas shall be taken into consideration. Taxies are allowed to pull over the road around the subway route to take or drop passengers, for instant stopping and leaving. At the peripheral areas towards the south and the north, where conditions permit, taxi waiting space or taxi-beckoning stops will be set, and the passenger-waiting space will be set at the hub station, flexibly. (5) Car access Car access shall be planned and arranged in compliance with the criteria of "P+R" (Parking and Transfer), based on the station land condition, the road network conditions and the traffic condition, and considering the whole picture of the railway network. In the process of preparing the detailed regional planning, focus shall be on reserving parking space around the remote subway stations. The above-mentioned access space for public transport will be controlled and reserved as the accessing land by the planning bureau to avoid being used by other projects. During the project construction, the Subway planning company and the commission for communication will take the lead to organize the public transport companies and the gardening &landscaping organizations to build respective facilities to be accessed to the subway stations as per the planning. Example: Erqi Square Station - the transfer station between Subways #1 and #3. (1) Traffic around the station The station is located at the intersection of Jiefang Road and Zhengxing Street and arranged in transmeridional way along Jiefang Road. Passengers can transfer between Subway #1 and #3. There are totally 5 entrances/exits for Subways #1 and #3 which are distributed on four sides of the intersection between Jiefang Road and Zhengxing Street. The station stand at the center of the old urban area where it is well-developed, densely populated, the most prosperous commercially and highly-concentrated with urban functions. At present, Bus Line No. 6, 603, 28, B17 have stops on Jiefang Road (stop name: Erqi 411      Square bus stop) which are closer to the subway entrance/exit while Bus Line No. 105 (south), 806, K906, 95, 32, 21, K6, K903, 93, 517 and 906 have stops at Zhengxing Street (stop name: Erqi Square bus stop) that intersects Jiefang Road, which also are closer to the subway entrance/exit. (2) Passenger flow features The passenger flow is dominantly mixed including travellers and commuters. The passengers walking to the station are distributed over the commercial space around it. Since railway transit stations concentrate there, most passengers from other stations also walk inside it and so there will be no bicycle parking space. passengers coming to it by public transports are by passing-by buses and the train station. (3) Improve the integrated traffic network Consideration is mainly given to access to the station on foot, by public transport, by bicycle, taxi, and private cars. The pedestrian system: Since the on-foot passenger flow comes from every direction around the station, squares are to be built around every entrance/exit of the subway and to be connected with established roads, and the established roads with footpath width less than 3 m will be rebuilt. Develop and improve sound planar crossing-street facilities and crossing-street facilities for transferring bus stops to provide a safe and comfortable on-foot system for on-foot and transferring passengers to the station. The public transport facilities: 2 bue stops on the west street will be reserved. 2 bus stops on Shuncheng Street will be relocated in order to minimize the distance from new stops to the subway entrance/exit, thus reducing the transferring time. The bicycle parking space: based on the demand from bicycle access and the organizational requirement, the first measure is to build more cycling roads and the second measure is to build 2 bicycle parking lots somewhere around the subway entrance/exit on the western street in order to reduce the frequency of bicycles crossing street effectively and lower traffic interference. The total area of both bicycle parking lots is 500 square meters including No.1 bicycle parking lot of 200 m2 to be located on the north side of the western street to serve the passenger flow on the north side of the station and No.2 bicycle parking lot of 300 m3 to be located on the south side of the western street to serve the passenger flow on the south side of the station; Taxi: Taxies are allowed to pull over the road around the subway entrance/exit for instance stopping and leaving to provide convenience to transferring passengers on the condition that the Zhengzhou rules concerning taxi management are met. 412      2. Organize passenger flow effectively and efficiently Understand how the passenger flow changes dynamically and take some measures to manage passenger flow (e.g. restrict traffic flow and direction at the peak hours). 3. Optimize the emergency response plan The organization responsible for operating the railway transit shall prepare emergency plans to address possible situation due to high passenger flow at the peak hours to incorporate relevant organizations, establish the interactive mechanism and carry out periodical drill. 6.3.2.2 Mitigation Measures of Sensitive Points Affecting by 2 Wind Pavilions at the Same Time The noise in buildings No.6 and No.5 in Huayuan Community exceeds the standard. Measures taken for them in this report include: (1) lengthening the silencer to more than 3 m which will reduce the noise of the wind pavilion by 10dB; (2) setting the main vents at the backward direction of the sensitive point. After taking the above measures, the predicted value of noise at these two sensitive points can meet the standard requirement. 6.3.2.3 Mitigation Measures of Cumulative Impact by the Vibration of 2 Subway Lines at the Same Time Sensitive points near the transfer station may be affected by two (or more) subway lines. The influence of shallow buried subway line to the sensitive point is much larger. Therefore, conservative vibration prevention measures shall be taken for both lines. The standard in “Residential, cultural and education areas” is taken as the limit value, and vibration prevention measures are proposed. For sensitive points with strict standards like residential area, school and hospital within 20 m, the mitigation measure of “steel spring floating slab” shall be adopted, and for “office buildings and commercial buildings” within 40 m, the mitigation measure of “elastic monolithic track bed” shall be adopted. The mitigation measure of “elastic monolithic track bed” will be adopted to building No.5 in Huayuan Community (No.300 Nanyang Road). The mitigation measure of “fastener” will be adopted to First Primary School on Nanyang Road. 6.4 Summary (1) Cumulative Impact on Cultural Relics Protection during the Construction Period: It is known from comprehensively assessing overall impact of foundation pit construction at Subway #1 and shield tunneling at Subway #3, i.e. superpose in linear way the above-described conclusions for impact of foundation pits at Subway #2 and shield tunneling at Subway #3 respectively, that after reinforcement Erqi Tower's maximal settlement is 19.2 mm within the limit of 20 mm and its foundation tilt is 0.0005, within the limit of 0.001. 413      A row of bored piles with the diameter of 800 mm are provided along the axis direction of Line No.3. The pile tops are connected into a whole by the 0.8m×1.0m crown beam. The pile bottom goes deep into 4 m below the shield tunnel of Line No.3, and enters into the (33) silty clay layer (permeability coefficient of 0.08m/d). Meanwhile, grouting pipes are embedded near the tower foundation. Information construction is adopted to the construction of foundation pit of Line No.1 and to the shield tunneling of Line No.3. Grouting reinforcement is prepared at any time according to the monitored deformation data. The cumulative impacts by Line No.3 during the operation period mainly include: the impact on the same sensitive point by wind pavilions at both sides of the subway at the same time; the impact of noises from two subways on one same sensitive point; the impact of the same sensitive point by the vibration of two subway lines; and the impact on the Traffic .. The cumulative impact of noise during the operation period can be mitigated by properly arranging the position of wind pavilion and cooling tower, selecting low noise equipment, lengthening the silencer, and other measures; the cumulative impact of vibration during the operation period can be mitigated by using the steel spring floating slab, and other damping measures. The traffic access space will be controlled and reserved by the planning bureau to avoid being used by other projects. During the project construction, the Subway planning company and the commission for communication will take the lead to organize the public transport companies and the gardening &landscaping organizations to build respective facilities to be accessed to the subway stations as per the planning in order to realize 5 accessing ways; Organize passenger flow effectively and efficiently. Understand how the passenger flow changes dynamically and take some measures to manage passenger flow (e.g. restrict traffic flow and direction at the peak hours); Optimize the emergency response plans. The organization responsible for operating the railway transit shall prepare emergency plans to address possible situation due to high passenger flow at the peak hours to incorporate relevant organizations, establish the interactive mechanism and carry out periodical drill. 414      7 Analysis of alteranative schemes First-stage project of Zhengzhou Rail Traffic Line No. 3 highlights line trend and comparison and selection of alternative scheme for station location during the feasibility study and design phase. Comparison and selection of alternative scheme of underground station construction scheme is taken into account during the construction stage. 7.1 Analysis of Zero Scheme Line No. 3 project of Zhengzhou Rail Traffic is urgent and necessary to the development of Zhengzhou and is mostly represented in following aspects.

Furthermore, the construction of rail traffic can reduce the emission of carbon dioxide by cars and thus protect the environment. Therefore the construction scheme is superior to the zero scheme view from any aspect. 7.2 Comparison and Selection of the Route Selection Technology of the Project 7.2.1 The Principles of Route Selection (1) The trend of the line and the allocation of stations shall be based on the “Master City Plan of Zhengzhou”, “Planning of Zhengzhou Rail Transit Network”, “Construction Program of Zhengzhou Express Rail Traffic”, and other master planning. The trend of the line and the allocation of stations shall be studied and selected by combining with the land development and the engineering construction conditions along the line to give full play to the high efficiency and backbone effect of passenger transport. (2) Allocation of stations shall be close to the distribution points of main passenger flow and various traffic hubs in order to attract the passenger flow maximally and provide convenience for passengers. Meanwhile, united consideration shall be given to the development plan of real estates along the line to drive the real estate development and improve the land efficiency. (3) Besides considering the transfer to other lines in the network, the connection with other public transportation modes shall also be handled for stations. The type of transfer station, the transfer mode and scale shall be properly selected according to the future passenger requirements to create better transfer conditions for passengers. (4) Auxiliary lines and other lines shall be properly provided according to the requirement of train operation and organization.

These intersections shall be avoided as far as possible. (6) Cultural relics and environment along the line shall be protected. (7) The buried depth of subway shall be properly determined according to the present situation and planning along the line. (8) Dynamic slope shall be adopted as far as possible for underground sections, especially the sections constructed by shield method to save the energy. 7.2.2 Comparison and Selection of Typical Lines In the feasibility research stage, the alternative scheme research is made to the trend 416      of lines at the north of the North Ring, the line scheme from Jinshui Road Station to Seven Feb. Square Station, and the line scheme of down-traversing the planned National Highway No.107 Interchange. 7.2.2.1 Comparison and Selection of Line Trend at the North of the North Ring This section is located at the starting section of Line No.3. After passing the North Ring Interchange along Nanyang road, Line No.3 goes further to the north in two routes: along Changxing Road and along Jiangshan Road, as shown in Fig.7.2-1.

The housing estate at the west has buildings of 6 storeys, while the housing estate at the east has buildings of 30 storeys. The minimum space between buildings of these two estates is only 30m, as shown in Fig.7.2-3 to Fig.7.2-5.   Fig.7.2-3 Line diagram of Jiangshan Road scheme 418                          Fig.7.2-4 North extension line plan of Jiangshan Road scheme            Fig.7.2-5 Photo of current status of north extension of Jiangshan Road (II) Recommended Scheme (Changxing Road Scheme) Line trend: after passing round the pile foundation of North Ring Interchange, the line goes north and down-traversing the plot at the northeast corner of the North Ring Interchange. The future line goes further north along Changxing Road, down-traversing Jialu River, enters into Huiji District, and goes further north along Qinghuayuan Road. Stations will be built in the planned Binhe Road intersection, Kaiyuan Road intersection and Dahe Road intersection.

From the engineering technology point of view, the recommended scheme is relatively better. Both schemes will down-traversing existing roads without conflicting with the planning. But affected by the Beijing-Guangzhou Railway at the west, the recommended scheme will attract more passengers. Furthermore, the plot at the northeast of Nanyang Interchange is under reconstruction, which can reserve spaces for Line No.3. From the long-term planning point of view, the recommended scheme will go further north, down-traversing Lianyungang--Khorgos Expressway and Jialu River. Stations will be built in the planned Binhe Road intersection, Kaiyuan Road intersection and Dahe Road intersection. The Kaiyuan Road Station is a transfer station with subway Line No.2, so the transfer conditions are good. From the social impact point of view, the recommended scheme is relatively better. From the environmental impact point of view, the recommended scheme will not down-traversing existing housing estate, so the impact of vibration on residents is small. From the finance point of view, the recommended scheme is better due to the reducing of construction difficulty. To sum up, this report argues that the recommended scheme is relatively better. 7.2.2.2 Comparison Selection of Line from Jinshui Road Station to Seven Feb. Square Station This section is located in the Seven Feb. business circle with dense surrounding buildings and busy traffic. It is one of the section with the most control factors, the largest implementation difficulty and the highest engineering risk on Line No.3. This line scheme shall be studied in emphasis, as shown in following figure.      Fig.7.2-9 Schematic diagram of comparison selection schemes of line trend and passenger attraction from Jinshui Road Station to Seven Feb. Square Station (I) Alternative Scheme (detour scheme at the west of Minggong Road) Line trend: a station will be built in Dashiqiao for Line No.3, the line will bypass the pile foundation of the interchange, go along the planned road at the west of Minggong 423      Road, and Xichenzhuang Station will be built after reaching to the backstreet of Xichenzhuang; and then, the line will curve off in R-320m to Jiefang Road, reach to Seven Feb. Square along the north of the planned interchange, and transfer with Line No.1. (II) Recommended Scheme (scheme along Minggong Road) Line trend: a station will be built in Dashiqiao for Line No.3, the line will bypass the pile foundation of the interchange, go along Minggong Road, and a station will be built at the intersection between Minggong road and Taikang Road; and then, the line will curve off in R-310m and passing through the plot of Huigangxincheng, bypass the pile foundation of Jiefang Road Interchange, and then bend to Jiefang Road, and reach to Seven Feb. Square, and transfer with Line No.1. (III) Comparison Selection of Line Schemes The routes of this line are compared and selected by considering the current status, planning, route conditions, passenger attraction, and other factors, as listed in table 7.2-2. 424      Table 7.2-2 Comparison selection of line schemes Review of scheme Advantages and Recommended scheme Alternative scheme1 Factors of comparison disadvantages Down-traversing seven buildings of 6 to 7 storeys at the north of Jiefang Road, and many low The difficulty of Down-traversing Huigangxincheng (28 storeys under construction), a few buildings, Recommended buildings of 1 to 2 storeys.

Square Station are fixed at both ends of this line, the scheme along Minggong Road is the straighter and the demolition amount is small. However this scheme is restricted by the Huigangxincheng under construction and the Memory Tower for “Feb. 7th”. Vibration and secondary structural noise will affect them during the operation period. The detour scheme at the west of Minggong Road is slightly far away from the Memory Tower for “Feb. 7th”, but the vibration during the operation period will still affect them. Furthermore, this line will down-traversing seven buildings of 6 to 7 storeys at the north of Jiefang Road, and many low buildings of 1 to 2 storeys. The demolition amount is large, and the social impact is great. Besides, buildings in the old housing estate are of brick-concrete structure, and the vibration resistance ability is poor, so the vibration and secondary structural noise will have large influence on them. The engineering cost of demolition is large, too. Based on the above analysis, this report suggests the use of the recommended scheme, which is the Minggong Road scheme. 7.2.2.3 Comparison Selection of Line Schemes Down-Traversing the Planned National Highway No.107 Interchange According to the road planning of Zhengzhou, a large interchange will be built at the intersection between National Highway No.107 and Shangdu Road. This interchange has not been built, and the current intersection is level crossing. By considering the present situation, this line is compared and selected, as shown in the following figure.   Fig.7.2-11 Schematic diagram of comparison selection schemes down-traversing the planned National Highway No.107 Interchange (I) Alternative Scheme (Scheme II) In this scheme, the line detours the intersection between the national highway and Shangdu Road. This line firstly detours to the south of the interchange, and returns to Shangdu Road after passing the interchange. (II) Recommended Scheme (Scheme I) 426      In this scheme, the line is directly down-traversing the intersection between the national highway and Shangdu Road.

Therefore, the advantages and disadvantages of the comparative schemes are mainly considered from the aspects of engineering and economy. The recommend scheme is straight, its influence on existing railway is small, and the engineering cost is low. There will be interchange at this intersection, which requires the proper consideration of the positions of piers during the design process to connect with Line No.3. The alternative scheme is curved and obliquely-traversing the high-speed rail, so the engineering cost is high. Therefore, this report suggests the use of the recommended scheme. 7.2.3 Comparison Selection of Positions of Key Stations 7.2.3.1 Comparison Selection of Schemes for Jinshui Road Station This section is located at the central area of Zhengzhou with dense buildings at its surroundings and prosper businesses. Both Jinshui Road and Nanyang Road are urban trunk roads. The road red lines are 60 m and 50 m, separately. Jinshui Road is one of the few urban expressways in Zhengzhou. It is the main channel linking the east and west, and the traffic flow is huge. The intersection between Nanyang Road and Jinshui Road is a large interchange, which has three elevated layers. The ground layer is mainly composed by sidewalk, non-motor vehicle land, motor vehicle land and bus lane; the second elevated layer is the direct connection of the east and west of Jinshui Road, and the third elevated layer is the direct connection of Nanyang Road and Minggong Road. Ramps are provided at all four quadrants at the surrounding of the interchange for vehicles to turn around. The maximum radius of the ramp bridge is 100 m, and the minimum radius is 26 m. All ramp bridges are made of reinforced concrete box girder, and the maximum span is 25 m. Both the main bridge and the ramp bridge are of bored pile foundation. Each pier of the ramp bridge is a pile foundation with the diameter of 1.5 m. Both ends of the 50m span of the main bridge have two pile foundations with the diameter of 1.5 m. 428      Other piers of the main bridge are of two pile foundations with the diameter of 1.2 m. Pile foundations are densely covered under the interchange, which will restrict the selection of line schemes. In addition, some low buildings of 1 to 5 storeys are located at the northeast corner near the Dashi Bridge Interchange. Jinshui Restaurant and low street shops are at the northwest corner. Street shops of less than 5 storeys are located at the southwest corner, which have the urgent need for development and reconstruction. Zhengzhou Acrobatic Hall and park are located at the southeast corner. To provide better service for passengers and to reduce the impact on surrounding environment, 2 schemes are studied for this section. The following figure is the schematic diagram for the comparison selection of the position of Jingshui Road Station.   Fig.7.2-12 Schematic diagram of comparison selection of Jinshui Road Stations Alternative Scheme (scheme I) In the alternative scheme, the station is located at the north of Dashiqiao Interchange. It is at about 300 m from Jinshui Road. After that, the left and right lines will down-traversing the interchange and Jinshui River from the east and west of Dashiqiao, and then they will bend to Minggong Road. (II) Recommended Scheme (scheme II) The station is moved to the south about 270 m compared with the alternative scheme. 429      It is separated island platform station. This station is located at the interspace between the east and west of Dashiqiao Interchange, and is about 30 m from Jinshui Road. After that, the left and right lines will down-traversing the interchange and Jinshui River from the east and west of Dashiqiao, and then they will bend to Minggong Road.

The passenger flow is large and it is very important. Therefore, the impact on the traffic of Jinshui Road during the construction and operation periods shall be considered in priority when selecting the position of station on Jinshui road. The recommended scheme has certain advantages both in passenger service and traffic influence. Its function is better. Although there are certain risks during the construction process and the engineering investment is slightly higher, certain engineering measures can be taken to guarantee the construction safety. Scheme II is recommended for this section with the principle of people oriented and function priority. 7.3 Comparison Selection of Construction Schemes The construction method has a decisive influence on the determination of structural type and the cost of civil works. The selection of construction methods is restricted by engineering geological and hydrogeological conditions, environmental conditions (current status of above ground buildings and underground structures, widths of roads, traffic status, etc.), plane position of the line, buried depth of the tunnel, excavation width, and many other factors. Meanwhile, the selection of construction methods will directly affect the ground transportation, the normal life of urban residents, the construction period, the degree of difficulty of the project, the implementation of urban planning, the development and utilization of underground space, and the operation effect. Therefore, the determination of construction method shall be adjusted according to local conditions, and overall consideration is required. The section type and construction method with reliable technology, advanced level and reasonable economic shall be selected. 7.3.1 Comparison and Selection of Section Construction Schemes The section type of the underground section is interrelated with the line, construction scheme and construction method. The section type is always different for different schemes. Common construction methods include mining method and shield method. The differences of them are listed in table 7.3-1. Table 7.3-1 Comparison selection of section construction methods Advantages Review of Scheme Mining method Shield method and Factors of Comparison disadvantages Passing through general strata, the Relatively easy in construction passing through the technology is usually geological fault, the many and complicated, Engineering Construction construction method Shield method the construction Technology difficulty is mature, and the is better difficulty is large, and construction the difficulty in difficulty and risk passing through are small geological fault is larger 432      Passing through Relatively easy in general strata, the passing through the construction geological fault, the Construction Shield method technology is usually construction method risk is better many and complicated, is mature, and the the construction construction risk are difficulty is large small The quantity of shield machines are determined The quantity of according to the time working shafts and schedule. The working surfaces are construction period Construction determined according Shield method is restricted by the period to the time schedule. is better station conditions, The construction but the automatic period is flexible and degree of the shield easy to control method is high, and the construction speed is fast Engineering Shield method Relatively good Good quality is better Difficulty in Relatively easy to controlling the ground control the ground settlement, and large Ground settlement during the Shield method land subsidence will be settlement construction period, is better easily caused if the and it is safe and supporting is not in reliable time The safety of Great construction construction can be difficulty and high risk guaranteed for strata Geological for construction in Shield method with complicated conditions sections with is better geology, large water complicated geological content and weak conditions surrounding rock Good control of surrounding buildings and ground Impact on Great influence on the deformation during Shield method ground safety of surrounding the construction by is better traffic buildings shield method, and the construction environment is good Social impact Utilizing existing Utilizing existing vacant land, land vacant land, land requisition and requisition and Land demolishing. The demolishing. The Shield method occupation occupied land area is occupied land area is is better large due to the due to the scattered construction concentrated sites construction sites Construction is likely Basically no impact Shield method Environmental Groundwater to cause the loss of on groundwater is better impact groundwater Vibration The impact of The working surface Mining 433      vibration and noise is has noise and method is large if blasting vibration in a long better operation is required term during the construction process The expense is 89,000 Yuan for dual line in The expense is each linear meter and between 95,000 Mining Engineering Finance about 75,000 Yuan for Yuan to 100,000 method is cost medium weathered and Yuan for dual line in better slightly weathered each linear meter rock. It can be seen from Table 7.3-1 that from the engineering technology point of view, it is relatively easy to penetrate through the fault by the shield method, which has the advantages of mature method, high automatic degree and fast construction speed. Compared with the mining method, the construction difficulty is small, the construction period is flexible and easy to control. It is relatively easy to control the ground settlement if using the shield method and the construction risk is small. Concerning with the impact on social environment and natural environment, if compared with the mining method, the shield method has good control to surrounding buildings and ground deformation, the construction speed is fast, the construction environment is good, and it has no impact on groundwater and other environment. Besides, the geological features of Zhengzhou are suitable for the shield method. Therefore, the shield method is mainly adopted for constructing this section. 7.3.2 Comparison Selection of Station Construction Schemes The construction methods of stations have decisive influence on the determination of the structural form and the engineering cost of civil works of rail transit. The selection of construction methods is restricted by engineering geological and hydrogeological conditions, environmental conditions (current status of above ground buildings and underground structures, widths of roads, traffic status, etc.), functional requirements of rail transit, plane position of the line, buried depth of the station, excavation depth, and many other factors. Meanwhile, the selection of construction methods will directly affect the ground transportation, the normal life of urban residents, the construction period, the degree of difficulty of the project, the implementation of urban planning, the development and utilization of underground space, and the operation effect. The construction methods of underground stations mainly include open cut method, undermining method and cover-excavation method. The advantages and disadvantages of these three methods are listed in table 7.3-2. 434      Table 7.3-2 Comparison selection of construction methods for underground stations Review of Scheme Advantages and Open cut method Cover-excavation method Undermining method Factors of Comparison disadvantages Open cut method is Construction difficulty Small construction difficulty Large construction difficulty Large construction difficulty better The undermining Construction risk No No Large construction risk method is bad Open cut method is Construction period Short construction period Relative long construction period Long construction period better Engineering The undermining Engineering quality Good construction quality Good Relatively good Technology method is bad The undermining Ground settlement Relatively small Relatively small Large method is bad The undermining Geological conditions Suitable for various geological conditions Suitable for various geological conditions Unsuitable for Quaternary soft soil layer method is bad Impact on underground Large, modification and correction of pipelines in the scope of the No modification and correction is The undermining Modification and correction of some pipelines pipelines foundation pit required method is good The undermining Social impact Impact on ground traffic Large (relatively small if constructing in the planned land use scope) Relatively small impact on ground traffic No impact on ground traffic method is good The undermining Noise Large influence scope of construction noise Short influence time of noise Not affected by construction noise method is good The undermining Air Easy to generate construction dust Short influence time of construction dust Not affected by construction dust method is good Environmental impact Continuous wall or sealing curtain can be used to reduce the impact on Continuous wall or sealing curtain can be used to The undermining Groundwater Large impact on groundwater level groundwater reduce the impact on groundwater method is bad Occupying urban green space and affecting the ecological Restorable after being occupied and short influence The undermining Ecology No impact environment time method is good Open cut method is Finance Engineering cost Lowest cost Relatively low Highest investment better 435      It can be seen from the above analysis that the open cut order method with the advantages of simple, fast, economic and safe shall be considered in priority if there are enough construction sites on the ground, the road can be occupied for a long time by dispersing the traffic, and if the underground pipes can be relocated. Compared with the undermining method, both the open cut method and the cover-excavation method have obvious advantages in construction safety, difficulty, construction period, waterproof quality of the structure, and engineering cost of civil works. According to the environmental conditions, the traffic dispersing conditions, the underground pipeline modification and correction requirement, the geological conditions, the buried depth of the station, and other factors, and by drawing on the successful experience of domestic subway construction, it is suggested that the underground stations of this line shall be constructed by firstly selecting the open cut method. The segmented inverted edge construction method or open cut + local cover-excavation method can be adopted for traffic trunks which need dispersing the traffic or crossing intersections. The geology along Line No.3 is mainly alluvial plain, the groundwater level is high and the geology is poor. The construction difficulty is really large for the station of more than 20 m in width. Therefore, the undermining method is generally not considered for the main structure of the station. Therefore, the open cut method or cover-excavation method will be used for stations on rail transit Line No.3 according to the recommendation of surrounding environment. Jinshui Road is the trunk road for the east-west traffic in Zhengzhou. The adoption of cover-excavation method will have small impact on ground traffic. All other stations are constructed by the open cut method. 7.4 Conclusions This report highlights the comparison and selection of alternative scheme in line trend, station location as well as the comparison and selection of alternative scheme in underground interval and underground station construction scheme. (1) In the comparison and selection process, comprehensive comparison of line operation condition, construction hardness, civil work investment, passenger flow attraction and environmental impact have been taken into account. For the comparison selection of the line trend at the north of the North Ring, both schemes will down-traversing the existing road and have no conflict with the planning. But due to the influence of the Beijing-Guangzhou Railway at the west, the recommended scheme can attract more passengers. Furthermore, the plot at the northeast of Nanyang Interchange is under reconstruction, which can reserve spaces for Line No.3. From the long-term planning point of view, the recommended scheme will go further north, down-traversing Lianyungang--Khorgos Expressway and Jialu River. Stations will be built in the planned Binhe Road intersection, Kaiyuan Road intersection and Dahe Road intersection. The Kaiyuan Road Station is a transfer station with subway Line No.2, so the transfer conditions are good. From the social impact point of view, the recommended scheme is relatively better. From the environmental impact point of view, the recommended scheme will not down-traversing existing housing estate, so the impact of vibration on residents is small. From the finance point of view, the recommended scheme is better due to the reducing of construction difficulty. To sum up, this report argues that the recommended scheme is relatively better. 436      For the comparison selection of line scheme from Jinshui Road Station to Seven Feb. Square Station, while the positions of Jinshui Road Station and Seven Feb. Square Station are fixed at both ends of this line, the scheme along Minggong Road is the straighter and the demolition amount is small. However this scheme is restricted by the Huigangxincheng under construction and the Memory Tower for “Feb. 7th”. Vibration and secondary structural noise will affect them during the operation period. The detour scheme at the west of Minggong Road is slightly far away from the Memory Tower for “Feb. 7th”, but the vibration during the operation period will still affect them. Furthermore, this line will down-traversing seven buildings of 6 to 7 storeys at the north of Jiefang Road, and many low buildings of 1 to 2 storeys. The demolition amount is large, and the social impact is great. Besides, buildings in the old housing estate are of brick-concrete structure, and the vibration resistance ability is poor, so the vibration and secondary structural noise will have large influence on them. The engineering cost of demolition is large, too. Based on the above analysis, this report suggests the use of the recommended scheme, which is the Minggong Road scheme. For the comparison selection of line schemes down-traversing the planed National Highway No.107 Interchange, the recommend scheme is straight, its influence on existing railway is small, and the engineering cost is low. There will be interchange at this intersection, which requires the proper consideration of the positions of piers during the design process to connect with Line No.3. The alternative scheme is curved and obliquely-traversing the high-speed rail, so the engineering cost is high. Therefore, this report suggests the use of the recommended scheme. (2) In the comparison and selection of key stations, Jinshui Road is the trunk road for east-west traffic of Zhengzhou. The passenger flow is large and it is very important. Therefore, the impact on the traffic of Jinshui Road during the construction and operation periods shall be considered in priority when selecting the position of station on Jinshui road. The recommended scheme has certain advantages both in passenger service and traffic influence. Its function is better. Although there are certain risks during the construction process and the engineering investment is slightly higher, certain engineering measures can be taken to guarantee the construction safety. Scheme II is recommended for this section with the principle of people oriented and function priority. (3) The interval construction scheme conducts the comparison and selection to the shield method and the mining method. It can be seen from the engineering technology that the shield method is relatively easy in passing through the geological fault, mature in construction method, high in automaticity and quick in construction, therefore it is smaller in construction hardness than the mining method, and is flexible in construction period, easy to control; The shield method is relatively easy in passing through the geological fault, mature in construction. Relatively in controlling the land subsidence and small in construction risk; From the aspect of impact to social environment and natural environment, the shield method construction is relatively good in controlling buildings around and the ground deformation, quick in construction, good in construction environment without any impact to environments such as underground water; In addition, the construction of this interval gives priority to the shield method taking the geologic characteristics of Zhengzhou into account. 437      (4) The station construction scheme conducts the comparison and selection to open deep excavation, covered excavation and subsurface excavation. The open deep excavation has larger environmental impact of ground traffic, land use, noise and dust than the covered excavation and subsurface excavation, however when the ground has adequate construction yard, the road can be occupied for long time by dispersing the traffic and the underground pipelines possess the modification and correction condition, construction method of the underground station should firstly consider the open excavation order method for its simplicity, quick speed, economy and safety. The open deep excavation has obvious advantages comparing to the subsurface excavation in construction safety, construction difficulty, and construction period, quality of structure waterproof and cost of civil work. According to the environmental conditions, the traffic dispersing conditions, the underground pipeline modification and correction requirement, the geological conditions, the buried depth of the station, and other factors, and by drawing on the successful experience of domestic subway construction, it is suggested that the underground stations of this line shall be constructed by firstly selecting the open cut method. The segmented inverted edge construction method or open cut + local cover-excavation method can be adopted for traffic trunks which need dispersing the traffic or crossing intersections. The geology along Line No.3 is mainly alluvial plain, the groundwater level is high and the geology is poor. The construction difficulty is really large for the station of more than 20 m in width. Therefore, the undermining method is generally not considered for the main structure of the station. Therefore, the open cut method or cover-excavation method will be used for stations on rail transit Line No.3 according to the recommendation of surrounding environment. Jinshui Road is the trunk road for the east-west traffic in Zhengzhou. The adoption of cover-excavation method will have small impact on ground traffic. All other stations are constructed by the open cut method. 438      8. Environmental Risk Analysis and Mitigation Measures Environmental risk analysis is intended to put forth preventive, emergency and mitigation measures against the impact on and damage to personal safety and environment caused by predictable emergencies (usually excluding manmade destruction and natural disaster) that occur during project construction and operation. Urban rail transit project involves huge investment, complex techniques, extensive aspects involved and influenced by engineering construction, and high operational requirements, thus it is necessary to identify and assess risk throughout project construction, and put forth corresponding measures against major risk. The results of risk assessment vary in different project phases and from the perspective of different stakeholders. The risk analysis in the first phase of project is mainly to identify and assess risk from the perspective of project decision making to identify and assess major risk, analyze the overall risk level, put forth countermeasures against major risk to provide basis for decision making and approval of the project, and serve as the foundation for risk management in subsequent engineering design, construction and operation. 8.1 Risk Analysis and Mitigation Measures during Construction Period 8.1.1 Identification of Risk Source Major risk source during construction period: Subway construction is characteristic of complex surrounding environment, various constructions, numerous underground pipelines, and high requirements for control of construction deformation; complex engineering geology and hydrological geology, and many uncertain factors; many structural forms, and crossed and varied construction methods, and high difficulty in construction and heavy pressure from construction period etc. Such characteristics are intensively embodied in high risk of subway construction, mainly during digging of base pit or interval tunnel of subway. Improper selection of construction methods and auxiliary methods such as open digging, hidden digging and shield tunnelling etc. tends to cause uneven settlement, ground collapse or bulging; Accidents such as collapse, roof fall, sand gushing water gushing, and water transmission etc. tend to happen during construction due to influences by multiple factors such as geological and hydrological factors etc.; Improper selection of construction methods and retaining program will cause breakage of adjacent underground pipelines or cracking, leaning or even collapse of surrounding constructions. For example, fire accident and explosion will be caused by breakage of gas pipelines; and damage of electrical wires and telecommunication cables will lead to power failure and suspension of telecommunication, or even electrical shock. Breakage of water supply and drainage 439      pipelines and sewage pipelines will cause suspension of water supply or accumulation of water in low-lying areas etc.. Major risk sources during operational period: According to survey of risk events during domestic and foreign subway operational period, the major risks and accidents during operational period come from social hazards such as arson or terrorist attack etc., and the accidents due to improper operation by staff and mechanical failure etc.. The aforesaid accidents have not only caused huge economic losses and tend to cause personal casualty and significant social influences. 8.1.2 Risk Analysis during Construction Period 8.1.2.1 Outline Construction of urban rail transit in China has undergone rapid development in recent years, and various areas in the country are speeding up planning and implementation of subway construction. However, the increasingly denser subway routes have brought along with themselves continuous construction accidents. A lot of accidents in urban subway construction show that subway construction will not only influence and destruct the safety of the environment(ground buildings, traffic, underground constructions and underground pipelines etc.) in the area influenced by construct6ion, but also endanger production, construction and safety of people’s life and property in serious cases, leading to serious economic losses. However, it is notable that inevitably certain secondary environmental disasters will be brought about to the surrounding environment upon occurrence of such accidents, or during remedy thereof. Thus it is necessary to carry out objective and fair assessment of the possible accidents and incidental environmental risk during project construction during environmental impact assessment for urban rail transit construction according to characteristics of project and the level of sensitivity of the ecological environment along the routes so as to take preventive measures for the areas greatly influenced thereby in time, which is of great significances for environmental safety in the areas influenced by construction. 8.1.2.2 Analogical Investigation of Environmental Risk Caused by Subway Construction Accident As shown in the investigation data, accidents such as bursting of water supply pipelines and ground collapse frequently occur in many large and medium-sized cities in China along with the accelerating urban construction in recent years. Collapse accidents caused by subway construction frequently happen in such accidents, for ground collapse accidents caused by construction of underground rail transit(hereinafter referred to as subway) are especially striking. Construction of rail transit has stepped into rapid development in various large cities in China in recent years to solve traffic jam on the ground. The accidents that occur during such subway construction and the environmental problems caused thereby have aroused extensive attention from various social circles. See Table 8.1-1 for the important accidents in domestic subway construction in recent years: 440      Table 8.1-1 List of Important International Subway Accidents Time Site Type and Cause of Accident Loss Ground collapse due to defects in construction Fengqing Avenue methods, and problems in site selection of 8 deaths; 13 persons November along No. 1 Subway of construction; There are requirement to hurry disappeared, and 11 15, 2008 Hangzhou through project construction to meet “construction injured; period”.

Thus it is necessary to pay great attention to environmental protection project and implement effective measures during construction. (1) Impact on Water Environment 442      According to statistical data, most of breakage of underground pipelines and ground collapse during subway construction occur in case of leakage of underground pipelines and mine tunneling method. As shown in the results of site investigation of the accident, the basic reason for ground collapse is stratum deformation caused by water and underground construction activities. Water sources can be divided into the original underground water in the stratum, and abrupt inrush of water due to breakage of pipelines. The accidents such as breakage of underground pipelines and ground collapse etc. will cause water and soil erosion in surrounding areas. In case water stoppage cannot be well solved during subway construction in stratum saturated with water, shifting sand or slurry will occur during construction, which will gush into base pit or tunnel suddenly and cause collapse, and the ground will be influenced in serious cases. (2) Impact on Atmospheric Environment As a lot of construction materials and various chemicals needed for construction are stored on the site of subway construction, certain impact will be caused on the surrounding atmospheric environment once fire accident happens on the site of subway construction. In addition, a huge quantity of firefighting water and the ashes of the substances produced during combustion or incomplete combustion will cause secondary pollution on the local surrounding underground water and ground water as well during fighting against the accident. (3) Impact on flooding The access line of Jialu River depot runs underneath Jialu River, and the main line transverses Jinshui River(at K8+550), Xiong’er River(at K12+900) and Qili River(at K17+300). The widths of aforesaid rivers run across by the line are 5m, 30m, 20m and 60 respectively, with the depths of river channel being 4m, 3m, 5m and 5m respectively. The anti-flood facilities of the aforesaid riverbeds have been carried out and designed according to the standard of withholding the greatest flood in 50 years, and the dyke will not be flooded by the greatest flood in 100 years. No influences will be caused on the stations of No. 3 line during the flood season. 8.1.2.4 Geological Risk Analysis The stratum within the depth of 30m under the line(K0+0.000~K25+200) is mainly Holocene Series stratum of Q4 with a depth of 0-19.0m. The major stratums are as follows: the surface is artificial fill and complex earth etc., then dense-medium dense powdery earth, and soft plastic -plastic powdery clay mixed with powdery sand and fine sand. The major stratums between 19.0 to 30.0m are medium-dense to dense tight powdery sand, fine sand and medium sand stratums. The aforesaid stratums belong to category I wall rock with uneven distribution of rock properties and ordinary engineering geological conditions. The stratums are composed of powdery earth, powdery clay, powdery sand and fine sand. Except for the sand stratum and its interlayer with high bearing capacity and low compressibility, the other rock and soil layers are mainly earth with medium and high compressibility, low strength and poor stability. The area belongs to area with medium risk level of geological disaster. The major categories of geological disaster are ground collapse, ground fissure, ground precipitation and uneven ground settlement. 443      Thus shield tunneling method is adopted for construction of the line(K0+0.000~K25+200) , and open digging and covered excavation method are adopted for underground stations(Xinliu Road Station, Shamen Road Station, Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station, Jinshui Road Station, Taikang Road Station, Er’qi Square Station, Shuncheng Street Station, Dongdajie Station, Chengdong Road Station, Future Avenue Station, South Fengtai Road Station, Zhongzhou Avenue Station, Tongtai Road Station, East Huanghe Road Station, East Nongye Road Station, Zhongxing Road Station, Boxue Road Station, East Hanghai Road Station). Meanwhile, relevant engineering measures and prevention methods have been taken for disposal so as to avoid geological disasters(mainly instability of tunnel wall rock, instability of base-pit slope, watergushing in base pit and tunnel water surging etc.) caused by engineering construction. 8.1.2.5 Risk Analysis for Construction Methods The major construction method adopted in subway construction in Zhengzhou is hidden digging (shield tunneling method), and those for subway station are open digging and cover excavation. Improper handling of any construction method adopted will cause serious environmental and safety accident. For example, there is a base pit constructed with open digging in the south section of No. 3 subway line of Guangzhou, which adopts the drilling pile as the retaining structure. Due to poor water stoppage between the piles, the slurry outside the retaining piles gushes into the base pit from among the piles suddenly, and cause ground collapse outside the base pit. Another case in point is as follows: Shield tunneling is adopted for construction of No. 4 Zhongshan Road on No. 1 subway line of Guangzhou. Due to water leakage in the cast-iron water supply pipes, part of the soil under the hard road surface was eroded, leading to hollow holes therein. Small stratum deformation causes breakage of water supply pipelines and erosion of a huge amount of water and soil, and ground collapse through passage of shield tunneling. Moreover, mine tunneling method is adopted for construction of the interval tunnel near Jingguan Bridge of No. 10 subway line of Beijing. Due to poor anti-deformation capacity of the joints of sewage pipelines, the sewage pipelines break and sewage and soil gush into the tunnel, and over 300 square meters of ground collapses due to interference by underground construction. 8.1.2.6 Risk Analysis for Running Across ther Municipal Projects No.3 subway line runs across the bridge piles such as Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line and Shiwu highspeed railway line etc.. Impact will be caused on the bearing capacity and deformation of piles, and foundation settlement due to stratum interference, and overturning of the above structure may happen in serious cases. Overall settlement and differential settlement of the rails, and unsmooth level of rails from front to back will be necessarily caused when shield tunneling runs across railway routes of Nachang Railway Station. Such problems will cause significant uncertain factors to safe railway operation. 444      8.1.3 Risk Classification evaluation The onstruction risks are classified into 4 classes according to the possibilities and loss classes of urban rail transit underground engineering construction risks. The risk classification refers to table 8.1-2. Table 8.1-2 Construction risk classes and handling Acceptance Class Handling measures Control program Response department criteria Headquarter high-level leader, and It must be highly focused, and Prepare control and middle-level take measures to prevent; alarm measures, or departments such as Class 1 Unacceptable otherwise the risk must be correct or adjust the headquarter Safety reduced to acceptable level. program; Office, Engineering Division, Chief Engineer Office It must strengthen the monitoring and take risk handling measures Prepare preventive Unwilling to to reduce the risk level, and the Class 2 and monitoring accept cost of risk reduction shall not be measures higher than the loss after risk occurs. All parties on site (site Strengthen routine owner representative, No risk handling measure Class III Acceptable management and construction unit, required, but require monitoring review supervision unit, design unit, monitoring unit) No risk handling measure Routine Class IV Neglectable required, but require routine management and Construction unit monitoring review The classification of open cut foundation pit risks are determined by four main factors of foundation pit depth, underground water conditions, surrounding interference degree of foundation pit and ambient sensitivity of foundation pit deformation. The open cut foundation pit risk classification considering depth impact will be regarded as basic classification of foundation pit risks, while the detailed risk classification, on basis of basic classification of foundation pit risks, will modify after considered necessary factors such as underground water impact, surrounding interference degree of foundation pit and ambient sensitivity of foundation pit deformation. After comprehensively considered various factors, determine in detail to classify the open cut foundation pit risk into several classes. For risk classification of shielded tunnel, it is determined according to country rock category and poor geologic conditions of shielded tunnel, spatial state of shielded tunnel (gradient, earthing thickness, turning radius and spatial distance from neighboring tunnel), stratum interference extent and environment sensitivity for stratum deformation. The risk classification for tunnel country rock category, poor geologic conditions and impact on underground water is considered as fundamental classification of shielded tunnel; the detailed risk classification will be corrected after considered spatial state of shielded tunnel, stratum interference extent and environment sensitivity for stratum deformation on basis of fundamental classification. 445      The shielded tunnel risk will be classified into several classes in detail after integrally considered various factors. 8.1.4 Risk Preventive Measure during Construction Period According to the general analysis of the accidents and cases during subway construction listed above, the following work shall be done well to avoid safety risk during construction, and reduce the environmental risk caused by construction accident: 8.1.4.1 Pre-Construction Investigation and Design of Risk Source Firstly, subway lines shall avoid important risk source if possible, which calls for making definite the important risk sources for the route, the specific position and current situation, and the risk level. According to the practical conditions of No. 3 route, the following major problems shall be investigated and designed as required by project construction: (1) Engineering rock and soil survey of wet-collapse stratum and liquefied stratum before line construction to find out scope of distribution, burial depth and thickness etc.; (2) No. 3 line project runs across three overhead bridges at North Ring Road-Nanyang Road, Nanyang Road-Jinshui Road, and Zhongzhou Avenue-Shangdu Road, and bridges piles of Longhai Railway, and Shiwu High-Speed railway line etc.. The line runs under a great many houses, and multiple pipelines such as water supply, rainwater, sewage, fuel gas, thermal energy, electrical power and telecommunication etc. are distributed within the construction scope, and large-sized pipe galleries and pipe culverts are buried in some sections. It is necessary to carry out detailed and comprehensive survey of the bridge piles and foundations, house structure and foundation the line runs beneath, and the pipelines within the influence by the construction, and detailed construction organization and design according to the construction methods, construction order, and relative relations with the bridge foundation, house foundation and pipelines, and the types and characteristics of foundation and pipelines in the initial period of project construction to reduce the mutual adverse influences. 8.1.4.2 Engineering Measures for Risk Control (I) Engineering Measures for Risk Control during Station Construction: (1) Preventive Measures against Geological Risks Appropriate enclosure program shall be determined according to the requirements for base pit and digging depth, and the engineering geological and hydraulic conditions on the site during open digging of base pits at each station on the line. Base-pit engineering bracing measures such as soil nail wall, slope protection pile and underground continuous wall etc., and engineering measures such as engineering water lowering, water stopping and recharging etc. are adopted during construction of base pit at the station. In case subsurface excavation method is adopted during 446      construction, it is hard to for a balance arch of natural stresses due to the thin earth covering the structural roof of the station, and poor self-stability capacity of the wall rock, therefore it is subject to collapse during digging. Due to the dense distribution of surrounding buildings along the subway line, it is improper to adopt water lowering measure with well outside the base pits. The underground water level along No. 3 subway line ranges between 2.5m to 14.0m, and the depth of base pit is between 17 to 23m. Thus the base pit lies below the underground water level. In case water stopping measure is adopted, it is proposed to adopt bracing manner with drilling pouring pile plus waterproof curtain for the two-floor station, and underground continuous wall for three-floor station. In case well points are needed to lower the water, water lowering during base pit construction can only be carried out inside the pit, and it is strictly forbidden to lower the water outside the base pit, and it is necessary to establish a certain number of backfilling wells inside the water-lowering tunnel formed due to water lowering outside the base pit, and strengthen the monitoring over precipitation, deformation and movement of the surface and surrounding construction. The specific methods are as follows: In case of no confined water within the project scope, the disposal measures shall be mainly water lowering, i.e. bury tube wells deep at the bottom of the base around the base pit. The underground water is pumped out through the submerged pump inside the tube well to reduce the underground water level 0.5 to 1.5m lower than the bottom of the base pit. Effective measures shall be taken during precipitation to lower the adverse influences on surrounding environment, and avoid large-area precipitation of the surrounding ground on the site and danger for the safety of the surrounding buildings. In case there is confined water within the project scope, and “transitional layer” with a certain thickness between the digging depth of the base pit to the top of the confined aquifer, the upper submerged water may be isolated with the suspended vertical waterproof curtain. Then reduce pressure to lower the water level for the confined water in most cases to avoid hidden water-related dangers such as flowing sands and earth debris on the pit wall, and heave-piping at the bottom of the pit. When the digging depth of base pit has approached or entered into the confined aquifer, water-lowering measures shall be taken to lower the confined water level to 2m below the digging depth of base pit, and the underground continuous wall or secant pile shall be taken as bracing structure. Bottom sealing of the base pit shall be taken if necessary to avoid water penetration and earth debris on the pit wall, and heave-piping at the bottom of the pit etc.. (2) Risk Prevention Measures for Pipeline Construction ① Disposal Measures for Existing Underground Pipelines: As for the underground pipelines that influence the depth and engineering construction price of the station(for example, sewage pipelines with depth over 3 meters), it is proposed to relocate them outside the project scope at one time to lower the construction difficulty and risk, and save the overall project investment. As for the underground pipelines with a small burial depth, characteristic of high 447      pressure and explosion, or high safety level and great difficulty in construction disposal that do not influence the burial depth of the station(for example, fuel gas pipeline), it is proposed to relocate them temporarily during the construction period to lower the engineering risk, and restore to the original place after the end of project. Generally, the underground pipelines vertically laid out along the station may be relocated temporarily. As for the pipelines that involve great difficulty of relocation, and whose relocation restricts the construction period of subway, and those that cannot be relocated due to influence of the slope degree, such pipelines may be suspended for protection during construction period. Generally, steel arm or steel framework shall be put up for suspension protection. As for the concrete pipelines, they may be replaced with steel pipes for suspended protection. Generally, the underground pipelines that runs across the station(or exit and entrance passage) horizontally may be suspended for protection. As for the underground pipelines that are close to the subway structural project with high requirements for own safety, or those that are subject to leakage, or may lead to construction risk, necessary protective measures shall be taken for them during construction. The specific disposal measure shall be formulated according to the opinion and requirements of the employer’s unit, and tracing, monitoring and measurement shall be carried out during construction period at the same time. ② Disposal Measures of Existing Ground Pipelines: The ground pipelines are mainly electric and telecommunication pipelines, and shall be relocated outside the influenced scope of the project during project implementation, or elevated and buried along with pipeline network upgrading to guarantee construction and pipeline safety. (II) Engineering Control Measures against Construction Risk of Interzone Tunnel (1) Protection and Disposal Measures for Interzone Tunnel Running Across Houses on the Ground No. 3 rail traffic line of Zhengzhou City runs beneath a great many houses, and house safety assessment shall be carried out, and the safety level of the buildings shall be classified before construction to guarantee safety of buildings. It is proposed to dismantle the buildings with a high risk, and then reconstruct or compensate them in other ways. In case it is qualified to carry out shield tunnel construction, adjustment of excavation and control of shield tunnel conditions shall be strengthened during shield tunnel construction, and carry out simultaneous filling and secondary supplementary filling, and carry out informationalized construction and management. The following major measures shall be taken during excavation of shield tunnel: ① Improve excavation control level, and adjust shield tunnel excavation parameter to guarantee soil stability of the excavated surface. ② Improve the water-tightness of the working surface; Improve the mobility and penetration parameter of the earth through infilling bentonite or foam agent into the earth cabin to prevent sprouting of spiral transmitter. 448      ③ Improve the sealing properties of the shield end; Take multiple shield tunnel ends to prevent entry of the earth into the tunnel from the shield tunnel end; inject grease into the shield tunnel end and strengthen the waterproof properties of the shield tunnel end; ④ Take simultaneous filling and secondary supplementary filling during excavation to fill in the crevice inside the rings, and cause the pipelining to support the stratum as soon as possible and control the ground settlement. ⑤ Do well in construction monitoring, and adjust construction parameter in time according to monitoring results. ⑥ Carry out necessary reinforcement measures for the foundations of the houses run across by the shield tunnel before excavation. (2) Risk control measures for foundation of bridges run across by inter-zone tunnel: The whole line needs to run across part of the bridges spanning over rivers and overhead bridges. According to the foundation data grasped at present, the most of the bridge pile foundations have been avoided on plane surface through adjusting the plane location and line elevation of the inter-zone tunnel of the whole line. In case of running across bridge pile foundation from the sides, generally optimal construction parameters may be adopted while strengthening the management of excavation parameters and status control, and carrying out simultaneous pressure grouting and necessary supplementary pressure grouting measure to guarantee its safety. In case of excessively large ground load, or close distance, compensatory filling may be adopted to duly reinforce the earth surrounding tunnel, or strengthen the pipe segment structure. As for intrusion of bridge pile foundation into the tunnel structure, it is necessary to dismantle such pile foundations before arrival of the shield tunnel machine. It is possible to take pile foundation underpinning, or pile dismantlement for bridge reconstruction. As the earth surrounding the tunnel may become loose due to passage of shield tunnel through pile foundation, and the friction resistance of pile foundation may decrease, grouting pipes shall be reserved in the tunnel to reinforce the surrounding soil. Meanwhile, high-pressure jet sprouting piles shall be established between the bridge pile foundation and the structure of the inter-zone tunnel for isolation. (3) Risk control measures for inter-zone tunnel running beneath Jinshui River etc. No. 3 rail traffic line of Zhengzhou runs across Jinshui River and Qili River etc., therefore on the one hand, simultaneous filling materials with light pollution for water resources shall be selected for tunnel construction, and on the other hand, the shield structure thrust force and filling pressure shall be controlled to avoid penetration of the slurry into river due to excessive pressure. In case the inter-zone tunnel runs across lake or river, the thickness of the covering earth shall be large than the diameter of the shield tunnel in principle, and anti-floatage shall meet the relevant requirement. 449      Carefully study engineering geological and hydrological geological conditions, and make definite the requirement of project construction for the properties and functions of the shield tunnel machine according to the characteristics of the project. Disposal of sudden accident shall be taken into consideration for allocation of shield tunnel machine; Put strict check over major excavation parameters, reduce pressure fluctuation, and adopt low-speed even promotion to avoid great interference with the soil. (4) Risk Control Measure in case of Inter-zone Tunnel Running Beneath Railway Zhengzhou boasts developed railway network, and the whole line needs to runs across the existing railways such as Longhai Railway and Shiwu High-Speed railway line etc.. The plane and vertical sections of the line have been optimized according to specific conditions to keep certain safe distance between the inter-zone tunnel and the line. The major control factors are excessive railway deformation and pipeline transformation according to the experience on the existing urban subway shield tunnel running beneath the existing railway. The following measures shall be taken: ① Improve excavation control level, and adjust shield tunnel excavation parameter, and guarantee the soil stability of the excavated surface. ② Improve the watertightness of the dregs on the working surface. Improve the mobility and penetration parameter of the dregs through infilling bentonite or foam agent into the earth cabin to prevent sprouting of spiral transmitter. ③ Improve the sealing properties of the shield end; Take multiple shield tunnel ends to prevent entry of the earth into the tunnel from the shield tunnel end; inject grease into the shield tunnel end and strengthen the waterproof properties of the shield tunnel end; ④ Take simultaneous filling and secondary supplementary filling during excavation to fill in the crevice inside the rings, and cause the pipelining to support the stratum as soon as possible and control the ground settlement. ⑤ Carry out whole sectional filling and rotary grouting reinforcement for the areas run across by the shield tunnel; ⑥ Take reinforcement protective measures with a certain aim for important pipelines, and control its deformation through isolation zone formed through reinforcement; ⑦ Establish pressure-relief vent to prevent excessive movement of earth due to high-pressure filling; (5) Inferior Geological Conditions There are powdery earth and powdery clay on the line at K0+0.000~K25+200 with low strength and poor stability. It is proposed to adopt shield tunnel method for construction. And the stations shall be constructed by means of open digging and 450      covered digging method. 8.1.4.3 Adopt new construction techniques and technology New prospecting equipment and comprehensive methods shall be adopted during construction to realize cooperation among various departments, and gradually find out specific conditions of urban underground facilities and establish 3-dimensional digital map of underground space. According to statistical data, most of the breakage of underground pipelines and ground collapse etc. caused during subway construction happen in case of leakage of underground pipelines and mine tunneling method. At present, domestic mine tunneling construction is still carried out mainly by means of manual excavation. Due to varied management capacity of the contractors and technical levels of the construction workers, or lack of clear knowledge about the stratum, underground water and pipelines, it is rather hard to properly carry out measures to control the underground water and stratum deformation. However, as open digging is visible and approachable during construction, it is easier to find abnormal conditions, and take emergency remedial measures in time and avoid accident. Shield tunneling depends on real-time monitoring of stratum and construction conditions by meters during construction, and can adjust construction parameters at any time. The shield tunneling machine can complete the prescribed construction operation automatically, and can strictly control stratum deformation and water stoppage. The optimal subway structural forms and construction method shall be selected according to the specific engineering geological and hydrological geological conditions, and the status of underground pipelines. Open digging construction shall be adopted for the subway stations and distribution sections in front of or behind the subway stations if possible. Except for mine tunneling method for the sections with ground constructions, fewer underground pipelines and lower underground water level, and more stable stratum, shield tunneling shall be adopted for the other sections of the interval tunnel if possible. In case mine tunneling method must be adopted due to difficulty in grooming ground traffic or transfer of underground pipelines, the scale of subway station constructed with hidden digging shall be strictly controlled without lowering the service functions. Meanwhile, steady and reliable technical measures to stop water and consolidate stratum shall be adopted. In addition, relevant project parties shall closely cooperate with the owner of the underground pipelines to find out the relative positional relations between underground pipelines and subway tunnel, and leakage thereof. Construction shall be carried out after consolidation of the site in case of serious leakage. Shield tunnel method is mainly adopted for construction of the project sections, which can effectively control stratum deformation and prevention of penetration of underground water, thus lower construction risk. Supporting and water-stopping measures such as diaphragm wall, drilling hole pile plus water seal curtain etc. have been adopted for subway stations constructed by means of open digging and cover digging of the project to control drainage and extraction of underground water and prevent ground settlement. 8.1.4.4 Strengthen monitoring and measurement during construction 451      Strengthen monitoring and measurement during construction(including structural deformation of tunnel, ground settlement, and pipeline deformation etc.) to realize informational construction; Establish risk management mechanism and formulate risk control standard to improve the risk awareness, management and technical levels of the construction staffs. Generally speaking, there will be signs before occurrence of subway construction accident. For example, excessively large or rapid deformation of retaining structure, or sudden changes in ground settlement, or water leakage in tunnel etc.. In case such problems can be discovered and handled in time, and confined to the control standard all the time, the accident will be avoided as a result. Therefore monitoring and measurement are the eyes and ears of the construction staffs and managerial personnel. They can carry out actions with a certain aim to avoid risk in case they can obtain clear information. It can be found through careful analysis of the previous accident that most of such accidents were caused due to loose or improper monitoring. Strict monitoring and monitoring measures shall be carried out against structural deformation of tunnel, ground settlement, structure deformation and settlement etc. when digging stations and sections that run across bridges and piles of Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line, Shiwu highspeed railway line and residential buildings. 8.1.4.5 Establish environmental safety technical management system for subway construction There are many practical cases on leaning of adjacent buildings, road collapse and breakage and dislocation of pipelines due to excessively large stratum movement due to underground project construction. Urban underground project is a risky project as well as a rather complex systematic project. Thus it is quite necessary to establish a set of perfect engineering construction environmental safety technical management system. To ensure the construction project of Zhengzhou Rail Transit Line 3 and construction personnel personal safety, avoid sudden major accidents and fulfill rapid and effective control and handling once accident happens, hereby prepare the risk management methods based on the principle of “prevention first, self-help in priority, uniform direction, works division” and it mainly includes construction risk identification, construction risk management system, construction risk early warning mechanism and construction risk emergency plan. For details see annex 2. See table 8.1-3 and 8.1-4 for risk analysis and and prevention measures of the railway stations, tunnels along Line 3 project.   452      Table 8.1-3 Construction risks and measures of stations Engineering Construction Risk No. Station Risk engineering category Description of basic risk conditions Solution proposal method classifications 1.

However, such risk is not totally inevitable. Domestic subway engineering circles have obtained rick experience in this aspect, and there are many successful examples as well. For example, Huangzhuang transit station of No. 10 subway line and No. 4 subway line of Beijing is constructed by means of mine tunneling. Such station is of a large scale and complex structure with a large number of surrounding constructions and dense distribution of underground pipelines, which is rarely seen even in the world. However, the project was smoothly completed through strict risk technical management throughout construction, and no construction safety accident happened during construction. 8.1.5 EHS Analysis and Mitigation Measures during Construction Period 8.1.5.1 EHS Analysis and Mitigation Measures during Construction Traffic accident has become of the reasonsfor the most injury and deaths to the public throughout the world. All the project staffs shall safeguard traffic safety when leaving for or from the worksite, and operating project equipment on free road or public road. The safety measures to prevent and control injury and deaths in traffic accident shall be intended to protect the project workers and road users, including the increase in traffic flow on the existing road, or major contents of the project in case of road transport. The following measures are requested to be taken: (1) Reduce simultaneous use of road by the passengers and construction vehicles as much as possible; (2) Cooperate with local community and authority to improve the road signs and increase visibility and increase the overall safety level of the roads,especially roads near school and other areas that involve children. Jointly carry out traffic education and safety education for passengers with local community(for example, publicity activity in school); (3) Coordinate with personnel handling emergency to ensure suitable first aid in case of accident; (4) Use materials purchased in local area if possible to shorten transport distance and reduce the possibility of traffic accident; (5) Adopt safe traffic controlling measures, and warn the passengers and vehicles against dangerous conditions with road signs and signaler. 8.1.5.2 EHS Analysis and Mitigation Measure against Contagious Diseases during Construction Period Contagious diseases have posed great threat to health of global public. Usually the health threat of large-scaled development project comes from poor sanitary conditions and living conditions, and infection due to sexual transmitted diseases and disease transmission medium. In view of lack of long-term effective measure therein, it is necessary to take various behavioral and environmental rectification measures to 469      prevent contagious diseases successfully. It is requested to take the following intervention measured within the scope of the project: (1) Carry out regular physical check for the workers; (2) Prevent transmission of the worker’s disease to local community by the following methods: carry out health education, for example information communication strategy, strengthen face-to-face consultancy work to solve systematic problems influencing personal behaviors; encourage individuals to take protective measures, and prevent transmission of diseases to others through use of condom. (3) Train medical staffs to treat disease; (4) Carry out immunity injection for the workers to improve health and prevent infection; (5) Provide medical care service; (6) Treat the patients in site medical organ or that of the local community to ensure easy access to medical treatment for the workers; keep the information on the workers in secrecy, and provide suitable nursing service(especially for mobile workers); 8.1.5.3 EHS Analysis and Mitigation Measures against Noise and Vibration during Construction Period The project is a large-sized construction project, and opening digging of the underground station(including the entrance and exit of the station, and civil construction of air kiosk), part of the underground sections, civil construction of vehicle depot and parking lots, and ground lines and ground stations, and underground construction of shield machine etc. shall be carried out during construction period. The aforesaid construction will use a large number of mechanical equipment with high noise and vibration such as excavators, air compressors, pick and heavy transport truck etc.. A series of health impacts on the construction operators due to long-term exposure to the aforesaid equipment of high noise and vibration. Hearing will be seriously influenced after long-term working or living in environment with noise above 90dB, leading to diseases of neurological system such as neurasthenia with major symptoms such as headache and sleep disorder, changes in EEG(for example changes in rhythm, low wave radiation and decrease of indexes), and functional disorder of autonomic nerves etc: Mechanical vibration will cause various adverse influences on human body: pale fingers and barriers to blood circulation, numbness and hurt of hand and wrist, dizziness and nausea etc., for the amplitude and frequency of various parties in the human body vary from each other during vibration, which will lead to abnormal position of organs in human body, and physical discomfort and melancholy etc.. The following measures shall be taken to reduce influence on construction operators by equipment with high noise and vibration: (1) Give priority to construction machinery with low noise and vibration during 470      selection of equipment, and regularly maintain and keep the construction machinery and equipment; (2) The constructors operating equipment with high noise and vibration shall strictly carry out working-rest system to guarantee sufficient rest, and alternating shift and overtime work are forbidden except in special cases. (3) Carry out regular physical check for the personnel operating equipment with high noise and vibration 8.1.5.4 Atmospheric EHS Analysis and Mitigation Measures during Construction Period Dust will arise due to digging and drilling on the dry ground during construction of stations constructed with open digging. Moreover, the ground surface will be exposed and water will evaporate to form dry particles and loose ground surface after destruction of the original vegetation during construction. Thus dust will be raised in case of high wind or earth refilling. A part of the dust is floating in the air, and another part fly down ground or surface of buildings nearby with the wind. Dust pollution will cause great damage during construction. The dust floating in the air will be inhaled by the construction personnel, which will not only lead to various diseases of respiratory duct, but also spread various diseases due to the a large amount of pathogen carried by the dust, which will seriously influence the physical health of constructors. The construction dust and decorative materials during subway tunnel construction, decoration and decoration of subway station contain volatile organic substances and gases such as formalin, benzene and dimethyl benzene etc.. Moreover, long-term exposure to such environment due to the long construction period of subway construction will cause serious influences on the health of the constructors, and tends to cause diseases of respiratory system etc.. During application of substation devices, it may involve the selection of insulator materials. A favorable insulator used at early stage contains PCB compound, which is a colorless or light yellow oily material difficult to dissolve in water and has many good chemical and physical characteristics such as high thermal stability, chemical stability, fat solubility, insulativity, viscosity and dielectric constant. However, it is soluble in fat and other organic compound with large hazard on human body. So the related materials containing PCB compound have been forbidden during installation of substation devices in domestic and it is normally replaced with corresponding rubbers so that it will not lead to pollution. The following measures shall be taken during construction period against the health damage caused by air pollution to the constructors: (1) Establish special personnel to take charge of cleaning on the site of ground construction; splash water and clean the site in time to reduce dust raised thereby. Duly sprinkle water during digging of dry earth surface to keep certain humidity of the operational surface. (2) The workers shall wear masks during tunnel construction. The ventilation system in the tunnel shall be kept in normal working state to guarantee sufficient amount of 471      ventilation. Construction inside the tunnel shall be stopped in case the ventilation system is damaged. (3) Environmental protection materials shall be used during decoration of the tunnel and subway station, and the content of formalin therein shall meet the requirements of relevant standards. (4) The constructors shall wear corresponding gas masks and gloves during installation of the equipment of transformer substation to prevent physical damage due to poisonous substances in the equipment. (5) In the process of construction, the personnel should wear work clothes, helmets, protective gloves, masks, goggles, etc., in order to avoid the damage caused by toxic substances in the equipment。 8.1.5.5 Spoil ground EHS analysis and mitigation measures The waste residue produced during the construction process will be transported to Yaohu spoil ground and Jiaoqiao spoil ground. In the process of transportation of waste residue in, attention must be paid to the following: (1) The waste residue should be cleaned up and transported away without delay, in order to ensure the construction site clean and tidy, so as to protect the body health of construction workers; (2) In the process of construction, the workers shall wear work clothes, masks, helmets, etc.; (3) Spray water on construction site on a regular basis for dedusting, and cover the bare soil; (4) The satisfactory vehicle washing and cleaning facilities as well as full-time cleaners are available. Vehicles entering and leaving the site must be washed and cleaned by the facilities. For the management of Yaohu spoil ground and Jiaoqiao spoil ground, the followings are required: (1) Don't pile or discard the waste residue without order, but separate it in terms of its type and use; (2) Set in the hazardous location signs or instructions such as security warnings to remind workers or other management personnel to pay attention to safety; (3) For rainy days, stop the transportation of waste residue into the spoil ground, and at the same time, establish a temporary cover of waste residue and the temporary drainage facilities. 472      8.2 Risk Analysis and Mitigation Measures during Operational Period 8.2.1 Risk Analysis and Mitigation Measures during Operational Period 8.2.1.1 Analogical Accident Cases during Operational Period (1) Cases on foreign subway accident 23 typical significant subway safety operational accidents at home and abroad in recent 30 years are summarized in Table 8.2-1. According to the analysis, at least 1201 deaths and 7952 injuries were caused in the 23 significant accidents, and the indirect losses caused thereby were immeasurable. Table 8.2-1List of Significant International Subway Accident Time Site Type and Cause of Accident Loss Subway train bump onto the February 1975 London, England over 30 deaths wall at the end of the tunnel Subway fire accident caused November 1986 London, England by electrical spark in the 32 deaths and over 150 injuries machinery room March 1990 Philadelphia, America Derailing of train 3 deaths, 162 injuries Derailing of train and fire at least 6 deaths, and over 100 August 1991 New York, America accident injuries Artificial release of March 1995 Tokyo, Japan 12 deaths, and 5500 injuries poisonous sarin gas 8 deaths, and 150 injuries July 1995 Paris, France Bomb explosion Subway fire accident by 558 deaths, and 269 injuries October 1995 Bak of Azerbaijan mechanical trouble Crowding due to excessive 54 persons were stamped to May 1999 White Russia number of passengers death June 1999 Saint Petersburg of Russia Subway explosion 6 deaths Subway train collision due to 67 injuries, including 7 serious August 1999 Cologne, Germany system trouble injuries Derailing of subway train March 2000 Tokyo, Japan and collision with another 5 deaths, and over 60 injuries train due to rail problem June 2000 New York, America Derailing of train 89 injuries Derailing of train due to over August 2000 Paris, France 24 injuries speed Fire accident and collision Salzburg, Austria November 2000 with another train due to 155 deaths, and 18 injuries mechanical trouble Derailing due to mechanical January 2003 London, England 32 injuries trouble February 2003 Daegu City, Korea Arson 198 deaths, and 147 injuries 473      Nearly two thirds of the subway operation was suspended, and August 2003 London, England Power failure in a large area about 250000 persons were trapped in subway At least 40 deaths and 100 February 2004 Moscow, Russia Bomb explosion injuries Train collision due to January 2005 Bangkok, Thailand 212 injuries artificial factors July 2005 London, England Successive explosion 52 deaths, and over 700 injuries 42 injuries, including 2 serious September 2005 Valencia, Spain Collision of subway train injuries Derailing of lightweight 1 deaths, and 83 injuries, September 2005 Chicago, America railway train including 17 serious injuries Derailing and overturn of July 2006 Valencia, Spain 41 deaths, and 47 injuries train due to overspeed (1) Domestic Subway Accidents Two subway trains collided on No. 10 subway line of Shanghai at 14:51 on 27th of 2011, which caused 271 injuries. Manual dispatching was adopted for subway tariff from Jiaotong University station to East Nanjing Road station on No. 10 subway line of Shanghai due to trouble in signal equipment at 14:10 that day. No. 5 subway train collided with the rear end of No. 16 subway train in the interval tunnel from Yuyuan to Laoximen at 14:51 due to sudden power failure of the equipment that day and suspension of operational signal. The operators of the No. 10 subway line adopted manual dispatching for traffic. However, failure to strictly abide by relevant management rules by the relevant personnel led to the accident. Cause of accident: The company has many emergency plans. However, as the trains shall go through maintenance and repair at night, and it is hard to carry out exercise during the operational peak period during the day, exercise has not been properly and fully carried out. Moreover, emergency exercise against fire accident, terrorist attach, and passenger evacuation etc. is carried out once a month on average, while there are rather few exercises on operational dispatching. The trains depend more on automatic system after installation of automatic safety orientation system, and almost no exercise on manual dispatching has been carried out. Preventive Measures against Accident during Operational Period The subway trains operate in a single direction under the semi-sealed underground space, and there is poor ventilation in the tunnel. Thus passenger evacuation will be greatly restricted in case of accident. On the other hand, trains can carry a large number of passenger, and belong to a public place with a high concentration of personnel and a rapid public means of transport with a high mobility of personnel, thus it is impossible to carry out strict security check for the passengers like trains and plane. Therefore it is subject to terrorist attack such as arson, explosion or biochemical attack etc., and the project needs to refer to the accident emergency plan of the operating subways at home and abroad to formulate strict preventive measures. Floodproofing measures for entrance during operation period: the subway station entrance shall be designed according to 100-year return period standard and be 15cm-45cm higher than the ground surface. In emergency, the station shall reserve 1m 474      high waterproof baffle plate to insert in case of emergency to avoid the flood generated from rainstorm entering the underground station. (2) Formulate emergency plan and carry out mimic exercise It is hard to totally eradicate accident and disaster, thus great attention shall be paid to formulation of emergency plan. “Prevention first” is the principle for safe and normal operation of subway. Preparedness ensures success, unpreparedness leads to failure. Different accident calls for different emergency disposal methods. The personal casualty and loss of property caused by accident and disaster cannot be minimized unless several emergency plans against emergency accidents are formulated in advance, and emergency handling capacities against emergency accident are strengthened. Rapid response and proper measures are key to disposal of emergent accidents and disasters. Emergency plan is a necessary supplement to daily safety management work, which include the major contents as follows: organization and formation of commanding system, and configuration of emergency equipment(mainly including alarming system, rescue equipment, firefighting facilities, and telecommunication equipment etc.), accident handling and restoration of normal operation. It is quite necessary to carry out mimic exercise on emergent handling of accident to prevent accident and guarantee safe subway operation in addition to strengthening ideological education on safety among employees, improve the awareness of group safety, perfecting various rules and regulations, and strictly implementing labor disciplines and operational disciplines, and establishing safety supervisory management organ. Strengthen awareness of safe production among all members and gradually improve the emergency capacities, capacity of concerted cooperation and comprehensive rescue capacity for accident of various specialties and types of work to serve the purpose of tampering employees. For example, Beijing subway has carried out mimic exercise named “prior emergency handling in case of train parked in the tunnel due to explosion” at Jianguomen station. (3) Handling Countermeasure after Accident---Safe Evacuation of Passengers According to the experience and lessons drawn from significant subway accidents throughout the world, failure to rapidly and safely evacuate passengers in time is an important reason for serious consequences. Thus rapid and timely safe passenger evacuation is an extremely important content in the whole subway safety system. A perfect safe passenger evacuation program shall be as much detailed and specific as possible. In case traffic cannot be restored within one to two hours, the subway company shall lose no time in contacting bus company and establish dedicated buses to different areas at each subway entrance to effectively evacuate passengers. The subway company shall undertake the responsibility of informing passengers after occurrence of accident instead of neglecting or even ignoring the right to know of the passengers under the excuse of “trouble”, which will cause horror and disorder among the passengers. (4) Establish expert system for handling accident Analysis and handling of subway accident is a complex technical work that involves much experience, and there are many reasons for subway accident. Rapid, effective and accurate identification of the reason for the trouble and taking effective measures to restore normal operation of the subway in time is work that is worthy of in-depth 475      research. Computer technology has been extensively integrated with engineering techniques such as safety management, safety assessment and risk analysis and prediction etc. in the field of safety science, and has promoted the development process of safety science. Safety analysis, accident diagnosis and safety decision making etc. can be carried out through accurate and rapid scientific calculation function of computer. At present, computer monitoring system is generally installed on subway. However, status monitoring function has not been fully performed, and a backstage trouble handling and analyzing system is needed to realize disposal of the monitoring signals, and fully realize intelligent monitoring of the system and improve the utilization rate of the whole monitoring system. There is a large amount of knowledge and experience at expert level in some field in the expert system, which can dispose of the problems in such field by utilizing the knowledge and means of solving problems of human expert. Disposal measures can be rapidly obtained through utilizing the expert’s experience to assist managerial personnel in disposing of accident and improving the safe economic operational level of subway. The expert system for handling subway accident is established on such basis. Once accident and disaster happen, the trains running on the whole route cannot go on operating according to the original prescribed operational chart, and the central control room must make scientific and accurate adjustment of all the trains in time. The ineffective management of the central control room in the arson case of the subway in Daequ of Korea led to failure to stop another train from running into the station that had caught fire and increase in the number of casualties, while most of the dead persons were the passengers in the second train. Automatic train control system shall include automatic train dispatching system in case of emergent accident and disaster. Such automatic dispatching system shall be a real-time expert system, and the automatic dispatching software shall be composed of fact base, rule base, reasoning machine and data blackboard etc.. The fact base is mainly for storing static facts related to reasoning; rule base is mainly for storing expertise of dispatching experts, for example, judging rules for trouble, and rules for adjusting operational chart etc.; The reasoning machine simulate the thinking modes of the dispatching experts, and utilize the rules in the rule base according to the facts in the fact base to carry out reasoning step by step. The intermediate structure of reasoning is temporarily stored on the data blackboard. Automatic dispatching system will formulate new train operational program in time to prevent aggravation of disaster. (5) Safety Summary for Operational Period As a large-capacity public means of transport, the safety of subway is directly related to the life safety of massive passengers. Safe operation is the primary objective and basic principle for subway transport. Transport safety of subway is a huge and complex systematic project, and the major factors influencing safe operation of subway are mainly people, vehicle, rail, power supply, signal and social disaster etc.. The subway operational management department shall do well in the following aspects: Strengthen publicity and education for passengers and staffs; ②Equip advanced equipment and testing system; 476      ③Establish monitoring and alarming system; ④Formulate emergency program; ⑤Carry out mimic exercise ⑥Pay attention to emergent evacuation of passengers after occurrence of accident 8.2.2 EHS and Mitigation Measures of Noise and Vibration during Operational Period The equipment of high noise during operational period mainly comes from noise and vibration during repair at the subway depot; the noise and vibration produced by the operating trains. The workers who are exposed to high-noise operation in the repair workshop of the depot for a long time shall wear ear plug etc.. The driver and crews of the subway train shall shorten their working time and receive regular physical check to guarantee physical and mental health. 8.2.3 EHS Analysis and Mitigation Measures for Air Environment during Operational Period Due to relatively sealed underground space, limited air circulation, and lack of direct shining, subway system is subject to contagious diseases. The research literature publicized by WHO and America EPA shows that generally the interior air pollution level is 2 to 5 times that of external atmospheric environment, and 100 times in extreme cases. The seriousness of air pollution in underground subway station which is more sealed is self evident, which will cause hidden danger to the heath of the staffs working in the subway station for a long time. Normal operation of the ventilation system shall be guaranteed and regular air quality test shall be carried out to lower air pollution in the underground space. Non-poisonous pesticides and herbicide shall be used during greening of the subway depots, the parking lots and transformer substation during operational period. 8.2.4 EHS Analysis and Mitigation Measures for Electromagnetic Environment during Operational Period As shown in analogical data, the maximum value of electromagnetic noise in the subway working zone is 61 dB(μV/m), which is equal to 1125μV/m; The possible maximum value of radio noise of the spark radiation formed through contact with the rail line is 108.5 dB(μV/m), which is equal to 0.25V/m. The aforesaid two values are smaller than the “output limit for public luminance” in “Protective Rules for 477      Electromagnetic Radiation”. Thus it will not cause adverse influences on physical health of the staffs. 8.2.5 EHS Analysis and Mitigation Measures for Dangerous Solid Wastes during Operational Period The dangerous solid wastes of the project are mainly the waste oil and dregs produced by oil-bearing waste water treatment system of the subway depots and the parking lots wiping tarpaulin of various processes, and waste transformer oil. The waste oil and dregs produced by the oil-bearing waste water treatment system, and wiping tarpaulin of various processes, and waste transformer oil belong to class HW08 in the “State List of Dangerous Wastes”, and such dangerous wastes shall be entrusted to relevant qualified units for harmless disposal. The staffs shall wear protective gloves and masks when exposed to such pollutants. 8.3 Conclusion (1) Risk during construction period mainly occurs during digging of base pit or interval tunnel. Improper selection of construction methods tends to cause uneven settlement, ground collapse or bulging; Accidents such as collapse, roof fall, sand gushing water gushing, and water transmission etc. tend to happened during construction due to influences by multiple factors such as geological and hydrological factors etc.; Improper selection of construction methods and retaining program will cause breakage of adjacent underground pipelines or cracking, leaning or even collapse of surrounding constructions. Major risk source during operational period: The major risks and accidents during operational period come from social hazards such as arson or terrorist attack etc., and the accidents due to improper operation by staff and mechanical failure etc.. The aforesaid accidents have not only caused huge economic losses and tend to cause personal casualty and significant social influences. (2) The stratum are mainly earth with medium within the depth of 30m under the line(K0+0.000~K25+200) and underground stations(Xinliu Road Station, Shamen Road Station, Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station, Jinshui Road Station, Taikang Road Station, Er’qi Square Station, Shuncheng Street Station, Dongdajie Station, Chengdong Road Station, Future Avenue Station, South Fengtai Road Station, Zhongzhou Avenue Station, Tongtai Road Station, East Huanghe Road Station, East Nongye Road Station, Zhongxing Road Station, Boxue Road Station, East Hanghai Road Station), the characteristic are high compressibility, low strength and poor stability. The area belongs to area with medium risk level of geological disaster. The major categories of geological disaster are ground collapse, ground fissure, ground precipitation and uneven ground settlement. Meanwhile, the subway station is constructed by means of opening digging and cover digging, and extraction and drainage of a large quantity of underground water in base pit tends to cause sudden decrease in underground water level and drifting sand, regional ground settlement and collapse, and deformation and cracking etc. of surrounding buildings. As No.3 subway line runs across the bridge piles such as Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road 478      approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line and Shiwu highspeed railway line etc,, and tends to cause settlement and deformation of the aforesaid buildings or structures, and many overturn the structures and endanger safety in serious cases. (3) Carry out pre-construction investigation and design of risk sources during construction period, and establish environmental safety classification system for construction period, adopt new construction techniques and technology, strengthen monitoring and measurement during construction, establish environmental safety technical management system for subway construction, and formulate emergency measures to lower risk. As No.3 subway line runs across the bridge piles such as Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line and Shiwu highspeed railway line etc, and various of municipal fundamental pipes,, it is necessary to carry out strict monitoring and monitoring measures against structural deformation of the tunnel, ground settlement, structure deformation and settlement etc.. Adopt earth pressure balance shield and select optimal construction parameters to ensure stable cutting face; strength the synchronous grouting and necessary supplement measures to control the settlement of structures, meanwhile it is necessary to take ground reinforcement measures. Supporting and water-stopping measures such as diaphragm wall, drilling hole pile plus water seal curtain etc. have been adopted for subway stations constructed by means of open digging and semi-cover digging of the project to control drainage and extraction of underground water and prevent ground settlement. Meanwhile, observe settlement of the surrounding buildings of the base pit, and monitor the underground water level etc.. (4)Take risk management measures such as strengthening publicity and education for passengers and staffs; Equipping advanced equipment and testing system; Establishing monitoring and alarming system; Formulating emergency program; Carrying out mimic exercise; strengthening emergent evacuation of passengers after occurrence of accident to lower the possibility of risk and personal and property losses caused thereby; 479      9 Dismantlement and Immigration Relocation 9.1 Immigration Information: The project will have social impacts related to the need for land acquisition and demolition of a number of structures like houses or enterprises. Based on the survey, about 767 people from 239 families will be affected by the acquisition of 55.3 ha of land, including 52.4 ha of collectively owned land; about 1,308 people from 449 families will be affected by the demolition of 35,347 m2 of private houses; and about 1,026 employees from 264 enterprises, institutes and small shops will be affected by the demolition of 66,313 m2 of structures. 9.2 Impact of the Project The areas impacted by the phase 1 project of No. 3 Zhengzhou rail traffic line under World Bank load are totally concentrated within Zhengzhou city.

(2) Populations Influenced by Relocation Relocation project at each station of phase 1 of No. 3 line involves 22 enterprises and units, involving 449 private families, and influencing 1,308 persons. 264 enterprises, institutions and shops will be relocated, involving 1,026 employees. As for relocation and land occupation caused by the project, Zhengzhou Municipal Rail Traffic Construction& Management Office has entrusted Wuhan University to make comprehensive RAP that meets the requirement of OP4.12 to fully restore the life of the immigrants and sufficiently compensate the losses, and maintain and even improve the living level. See RAP of the project for specific contents. The project will be supervised by internal and external monitoring agencies for implementation of 483      RAP. 9.5 Environmental Impact Analysis and Comments on Relocation 9.5.1 Rationality Analysis on Relocation (1) No Economic Influences Influenced relocated households, enterprise, and shop owners and employees can receive rational monetary compensation or relocation compensation in kind, and various land attachments influenced have been compensated according to replacement cost. No labor force influenced will lose job permanently due to influences on their units or land requisition. (2) Public Facilities Improved The public facilities of the community and the community environment etc. influenced by the project will be restored to level before relocation, and efforts will be made to improve them. The relocated areas are mainly located around each station, and the dismantled houses will be replaced by new urban infrastructure, and will be planned and constructed according to urban rail traffic as a whole. The traffic facilities and commercial supplementary facilities around each relocated station will be improved in essence, and the community environmental will be improved fundamentally after project completion. 9.5.2 Influences of Relocation on Employment and Economic Income (1) Influences of Relocation on Employment Mainly 264 shops will be influenced during relocation, involving 1,026 shop employees. The shops cannot operate during relocation, and employment of the aforesaid employees will be influenced. In addition to he relocation compensation for the aforesaid relocated shops, temporary relocation subsidy in the amount of 4% of the appraised price of the relocated buildings in the real estate market will be paid for the enterprises and shops that have suspended production or business due to relocation. (2) Influences of Relocation on Economic Income The means of compensation for relocation this time includes monetary compensation and compensation in kind to guarantee the economic income thereof will be increased instead of being lowered due to relocation. Compensation for houses dismantled: The influenced populations can obtain suitable residences from the market on their own through monetary compensation, or resettlement houses will be arranged for house replacement for the relocated 484      households, thus the normal living conditions thereof will not be influenced due to project construction and relocation. Compensation for land requisition and relocated enterprises: production resettlement and restoration is to restore the normal production and business activities of the influenced populations due to land requisition or relocation of the project, including compensation or replacement of the business venues of the enterprises and shops, compensation for relocation and transition, and losses due to suspension of production so that the influenced populations will obtain production and business conditions and income no lower than the original conditions. Meanwhile, proper arrangement will be made for the long-term living of the peasants depending on the requisitioned land to guarantee their living level will be improved instead of being lowered due to land requisition. 9.5.3 Environmental Impact Analysis in Relocation Zone The major environmental impacts on the relocation zone during dismantlement and relocation are the environmental noise influences due to dismantlement of surrounding old houses, and the impacts due to construction dust and construction rubbish. The major source of impacts of environmental noise is the noise caused due to operation of relocation construction machinery, with the maximum noise exceeding 100dB. In addition, the aforesaid houses involved in relocation lie in urban center with dense concentration of surrounding buildings and a high density of population. Therefore there is a large number of populations influenced by noise of relocation. However, due to short relocation cycle, it is necessary to do well in construction organization program, and select equipment with low noise if possible and avoid explosion operation while doing well in publicity for the surrounding residents and units. Generally, the noise caused by relocation is acceptable for the residents. Dust pollution will be caused due to destruction of buildings during relocation, and the pollution index such as PM2.5 in the air will be greatly increased in case of great wind. Thus it is necessary to avoid great wind during relocation and do well in water sprinkling and dust reduction. A lot of construction rubbish will be produced during relocation, and Zhengzhou municipal administrative department shall carry out coordination. The construction rubbish shall be disposed of in the construction rubbish site or landfill site of Zhengzhou city. 9.6 Environmental Protective Measures for Relocation 9.6.1 Planning and Design The specific measures during project planning and design are as follows: Carry out program optimization, comparison and selection, and give more 485      consideration to the influences of project construction on local social economy; Try to utilize the empty lands and greening land on both sides of the urban roads if possible to reduce occupation of the existing roads and urban built zones in case land occupation is unavoidable. Carry out site survey repeatedly when relocation is unavoidable; Reduce amount of relocation and provide convenience for travelling by urban residents if possible according to the layout characteristics of surrounding traffic facilities and municipal facilities while meeting the basic travelling demands of the subway passengers. Give sufficient consideration to the factor of land requisition and relocation, and reduce the amount thereof when comparing different design programs. 9.6.2 Project Implementation The rail traffic group relocation office will take the following measures during construction of No. 3 rail traffic line to reduce inconvenience brought to influenced populations as much as possible. (1) Rationally arrange construction plan and traffic organization design to lower the influences of subway construction on the surrounding environment and traffic order. Carry out scientific design and reduce enclosure area to the greatest extent during enclosed construction while giving sufficient consideration to various influencing factors and complete excavation and backfill within the shortest possible time; Construction shall avoid peak time on crossroads with busy traffic; It is strictly forbidden to carry out rude construction and destroy the original pipelines. In addition, necessary warning signs, lamps and guiding marks shall be established for convenience of passage by passengers and vehicles. The site shall be cleaned and traffic shall be opened in time after completion of construction. (2) The deserted earth dug out during engineering construction shall be transported in time, and shall not exceed load limit during transport. Measures shall be taken to guarantee no littering of earth from the transport vehicle on the way. The earth on the wheels shall be washed clean before the vehicle runs out of the site to prevent littering of earth everywhere and influencing environmental tidiness. Meanwhile, cleaning system shall be carried out for the roads in front of the gate of the construction unit, and the deserted soil, if any, shall be cleaned in time. (3) Project construction shall not be carried out between 10 pm to 8 am on the next day within 200 meters to the residential area. Meanwhile, the construction unit shall give priority to that during selection of construction equipment and methods, and shall adopt low-noise machinery. Noise elimination or control measures shall be taken for the construction machinery for the construction site that carries out construction at night and influences surrounding residents. Meanwhile, establish temporary sound screen etc. around the construction site, or in areas with concentrated residents to guarantee sonic environmental quality of the residential areas. (4) The project construction unit shall contact the local environmental sanitary department, and clean the domestic wastes on the construction site in time to guarantee site tidiness of the construction area. 486      9.6.3 Requirements for Environmental impact assessment during Relocation (1) Select low-noise equipment during dismantlement of buildings and avoid explosion operation if possible. It is forbidden to carry out relocation at night(22： 00~6:00) . (2) It is forbidden to carry out dismantlement and relocation in case of great wind.

Others 4.63 10.3.1.3 Analysis of Survey Results of Monographic Questionnaire: The following conclusions can be drawn through analysis of the survey statistical data in Table 10.3-2: Firstly, it is found from the survey that the influenced population have known more about the Zhengzhou Rail Transit Project and the policies on demolishing compensation for more than 72% of citizens know clearly the Rail Transit Line (RTL)3# and over 87% support its construction. This is because Zhengzhou, in recent years, has conducted large-scaled urban construction, and the land requisition and 492      demolishing is quite normal to citizens there who also are aware of the relevant policies more or less. In the meanwhile, most citizens are expecting the subway construction and operation to alleviate the increasing urban traffic congestion and so they are more concerned with and sensitive to news about RTL #3. Secondly, though with expectation and positive support to RTL#3, many citizens are also worried about some potentially negative impact from its construction, for example, land requisition and demolishment will lead some population to residential loss, relocation of enterprises and store may have influence on employment of citizens along the line, and construction at the down-town area may possibly compound traffic congestion causing more difficulties for people travel. For this reason, some citizens proposed some concerns in RTL#3 construction: first, open spaces at both sided of the current roads shall be made as full use of as possible in the construction of the subway inlets/outlets and the kiosks; second, the subway shall be built in an scientific order and shall not affect more on the surrounding environment and traffic. Also, some other citizens suggested building RTL#3 in phases to minimize the negative impact. Thirdly, the intent of house resettlement: most citizens are willing to resettle in the way of property right transfer. More than 40% of them expect the most to resettle back to their current residence after the Subway stations are built for their current locations are advantageous in residence and environment. Some residents hope to resettle by giving economically affordable housing but are worried that the governments cannot publish such a preferential policy because average households are not qualified for this in normal conditions. About 22% of households are willing to receive money for compensation because from our survey they are known to own more than one houses and their residence will not be affected by construction of RTL#3. 10.3.1.4 Monographic Cooperation---Public Participation in Feedback of Opinions During the period Apr. ~ May 2012, RTPMO and the Project-related Emigrant Center of Wuhan University, had summarized and generalized suggestions and opinions given by the impacted population during the social/economical investigation on the influenced population and the public participation, and considered or introduced these in their development of the emigrant resettlement action plan. Table 10.3-3 shows feedback toward public participation and consultation opinions to date. 493      Table 10.3-3 Public Participation, Major Consultation Opinions and Solution Program for Zhengzhou RTL## Project Funded by the World Bank Reason and Issue Consequences of Solution Issues 1） During the Village-in-City rebuilding, the two villages will be given 10% of total requisitioned Villagers of land for independent development and operation to Laoyancheng and compensate for the financial loss to the impacted Influences by Guchengcun, already population. land with insufficient land, 2） After stations, parking lots and vehicle depots are requisition will be hard to get employed once their built for RTL#3, employment opportunities for land lost. some auxiliary posts such as securities, cleaners, ticket clerks will be given to competent members of household with land loss in priority. 1） Carry out site survey during project design for many times and try to avoid or reduce passage through concentrated areas of resident’s houses, and arrange the exit, entrance and air kiosk on both Construction of sides of the current roads; Select the program with entrance and exit and the most economic number and structure of Influences of air kiosk will cause constructions when resettlement is inevitable. resettlement resettlement of a certain number of 2） After the subway inlets/outlets and the kiosks are buildings built and when Zhengzhou RTPMO is building residential buildings over the demolished sites, the original residents shall have the priority right to select and own housing by property right transfer based on previous house’s building area. 1） Optimize the direction of the routes and establishment of stations, reduce unnecessary land requisition and resettlement, and minimize the number of the enterprises and shops to be resettled. 2） Rationally arrange construction cycle, and control construction cycle as much as possible.

It is planned to have 21 Project Profile  stations at the average interval of 1.29 km , a vehicle depot and a parking lot. The routing is shown in the figure below. 516      The negative impact of the project includes: the project will have some effect on sound/vibration/water/ecologic environment and atmosphere (e.g. vegetation damage, waste water , noise and flying dust from construction) which can be mitigated by the project owner by measures such as reducing noise level, suppressing dust and waste water treatment, within the short period of construction. Through the traffic dispersion, waste water treatment, noise reduction and water spray measures, their environmental Main Environmental impacts  impact will be minimized during construction. During operation, the noise and vibration of the fans and cooling column will have adverse effect on residents. By reasonable design and selection of fans and cooling columns, installation of sound-proof hood on the cooling column, use of longer mufflers for the air kiosks, setting and installation of railway shock absorbers and use of elastic supporting blocks to support the one-piece track bed, and use of steel-spring floating-slab track bed and so forth, the impact of vibration on environment will be controlled within the level set out in the national standards. The economical, environmental protection and technically feasible principles are considered in selection of the route. During the design, construction and operation, effective protection measures will be taken for the social/ecologic/sound/vibration/electromagnetic/water environment, the atmosphere and the soild waste to control effectively the adverse effect and to contribute regional economic development and a stable society along the route. The project is considered freasible from the point of environmental protection view.   Educational Name Sex Age Nationality Level Working Unit or Occupation Contact Residence 517      1. what do you think of the current condition where the project is to be located?□ Very good □ Good □ average □ poor Please tick the environmental issue you are the most unsatisfied with □ Noise □ Vibration □ Flying dust□ Waste water □ Traffic jam □ Other Please in detail 2.

The interviewees may be mainly those directly influenced by the project construction, and the opinion forms are densely distributed along the routes and around underground stations. 714 forms have been recovered, with the recovery rate being 79.3%. Of the citizens living along the route, 89.08% supports the project and 10.92% don’t mind. 520      (2) In the first questionnaire, most of citizens along the route are not satisfied with the current local conditions. In this one on investigation of the unsatisfied environmental condition, most highlight the traffic jam (21.57%), followed by flying dust (37.39%) and noise (31.23%) during construction. 32.21% believe this project will aggravate the current environment while 35.57% think the environmental impact from the project is temporary and will be alleviated after the project is over and the urban traffic congestion will be relieved substantially after it is built. In addition, 11.76% believe the project will have no effect on the current environment. (3) For the environmental impacts during construction: the public are the most worried about flying dust (60.5%) and noise (45.52%), followed by vibration 30.67% etc. In this questionnaire highlighting the environmental measures taken during construction and operation, for the question about the noise interference arising from excavation of the stations, 50.84% believes the need to make the fence for construction higher while 49.16% prefer to financial compensation. For the short-time impact during construction, 85.71% can basically withstand but require taking mitigating measures and 10.64% are acceptable. (4) For the environmental impacts during operation: the public are the most worried about noise (40.34%) and smelling kiosks (38.24%), followed by vibration (35.85%), electromagnetic interference (20.03%) and water pollution (6.02%), damaged cultural relics (2.94%). For measures on noise, kiosks and vibration during operation, the public requiring building of acoustic barrier and claiming financial compensation for the noise account for 41.74% and 29.83%, respectively, while some citizens select to install ventilation sound-proof windows and relocate. For the measures to be taken during operation, more than half of respondents agree to take better isolation vibration measures and make it deeper underground, and claim financial compensation. For protective measures from kiosk smelling, most of the respondents agree to locate kiosks far away from the residential area (43.42%) and take measures to eliminate the smell (49.72%). (5) For the attitude toward and requirement on the environmental protection measure to be taken during construction: 59.8% of respondents agree and are satisfied, 21.75% are satisfied with measures with no comments. 18.63% require more measures. (6) For the attitude toward and requirement on the environmental protection measure to be taken during operation: 65.13% of respondents agree and are satisfied, 22.27% are satisfied with measures with no comments. 7.9% require more measures. From the 2nd questionnaire, it is known that the public along the RTLK#3 know more about the routing and the stations as well as the environmental impacts to be brought by the project during the construction and the operation, and are basically satisfied with the measures proposed after being informed of the measures on noise, vibration, air, ecology and water during construction and operation and hope these measures will be implement practically during the project implementation. 10.3.9.5 Treatment on feedbacks from public participation The result from the 2nd questionnaire indicates a vast majority of respondents are positive in RTL#3 and hope the project is implemented as soon as possible. They are satisfied with the treatment on previous feedbacks. They are informed of many 521      policies involved in the project, get familiar with the environmental protection measures proposed for this project and hope these measures are strictly complied. Table 10.3-15 Summary of main comments from public participation and the treatments Main No Public citizens Solutions comments The public are informed of the traffic dispersion plan which is more detailed, and the related entities shall base on the place to strengthen traffic management, Measures to arrange construction, occupy less road and quicken Citizens within the 1 mitigate the the progress during construction so as to ensure a free project area blocked traffic people and vehicle flow. For the details, see the traffic dispersion plan list 5.10-7for each station in the environmental protection measures Noise impact during construction: use low-noise machineries as possible, machineries failing to meet the national standard are not permitted to work, frequent maintenance and service will be made to the machineries during construction; loud-noise machineries (loaders and vibrators) are not allowed to Measures to work at night (22:00 ~ 6:00). For working in the day mitigate such Citizens within the time, impact on schools shall be reduced as possible 2 pollution as project area by avoiding construction activities during the class noise during hours. After operation, the environmental protection construction measures will be taken at any places along the line where the sound level is beyond the standard to ensure all places along the line sensitive to sound meet the standard. For details, see the summary list of environmental protection measures 11.6-1.11.6-2 The underground sections will be mainly impacted by the environmental control devices at stations. The mufflers will be extended to at least 3 m long at 13 kiosks with investment about RMB 1,950,000, the super-low-noise cooling column will be used at 9 stations with investment of RMB 2,700,000 while the Measures to environmental control devices will be invested with mitigate noise Citizens within the RMB 4,650,000 in total. 3 during project area For the heavily-impacted noise-sensitive places, the operation acoustic-proof building may be used to protect the sound-receiving locations, for instance, use of ventilation soundproof windows may reduce indoor noise by 20 dB. The soundproof ventilation window which is not expensive is used as an auxiliary measure because of affecting vision and ventilation thus resident’s daily life. 522      10.3.10 Public Notification on Site       Hanghaidong  road  Erligang Sub‐district Office  Sub‐district  Office        Jiefang Road  Sub‐district  Office  Minggong road Sub‐district Office      Liuzhai Sub-district Office West Str. Sub‐district Office    Chengdong road Sub-district Office Changxing road Sub‐district Office  523        Nanyang Road  Sub‐district  Office  Beixia Str. Sub‐district Office  Fig. 10.3-5 Pictures of Public Notification at different Sub-district Offices 10.3.11Public Notification on “Environmental impact assessment Report on RTL#3 of Zhengzhou Funded by Loan of World Bank” “Environmental impact assessment Report on Phase I Project of RTL#3 of Zhengzhou Funded with the Loan of World Bank” is publically notified on the official website of the World Bank (http://www.worldbank.org.cn/), and the information on the contact person, telephone and contact address etc. are left on the website to ensure timely and effective collection of public opinions during period of public notification. The deadline for receiving the opinion lasts till publication of the environmental impact report. 10.3.12 Feedback Mechanism for Public Opinions Phase I project of Zhengzhou RTL#3 involves numerous residential areas, enterprises and public institutions and so will be built for a longer period during which part of residential areas, schools, hospitals and stores will be impacted by noise and vibrations arising from the project and also the traffic, income and living of residents will be affected. Moreover, some residents have been involved in impacts caused by resettlement.

Thus in addition to calculating investment and expenses for controlling pollution, the possible environmental and economic effects shall be accounted during analysis of economic gains and losses due to environmental impact. Means of Assessment and Analysis The economic gains and losses due to environmental impacts of the project are comprehensively assessed by means of static analysis method, and conclusion is drawn from environmental and economic perspectives. (1)Net Benefits of Evironmental Protection Investment Calculation of net benefits of environmental protection investment is intended to 612      assess the dominant environmental impacts of the project(beneficial or adverse impacts). The calculation formula is as follows: B 总=(B 措-K)+B 工–L 前: As shown in the formula：B 总: Net benefits of environmental protection investment; B 措 : Environmental economic benefits produced by environmental protection investment; K : Environmental protection investment and expenses; B 工 : Environmenal and economic benefits due to environmental impacts of the project; L 前: Environmental and economic lossed in case of no environmental protection funds (2)Investment Efficiency Ratio in Environmental Protection The benefits and expenses ratio of investment on environmental protection must be calculated to assess the rationality of investment on environmental protection, and feasibility of environmental protection. The calculation formula is as follows: E 总=(B 措+B 工–L 前)/K In case E 总≥1, it shows that the environmental economic benefits of the project are larger than the environmental protection expenses, and the project is accpetab le. In case E 总<1, it shows the environmental protection expenses of the project is larger than the benefits obtained, and the project shall be given up. The larger E 总 is, the better effect of environmental protection investment will be. (1) Ratio between Environmental Protection Investment and Capital Construction Investment Comparison of the index with that of similar domestic projects can confirm the rationality of the project. 11.8.2.2 Analysis of Economic Gains an Losses due to Environmental Impacts The economic gains and losses due to environmental impacts of the project are comprehensively assessed by means of static analysis method, and conclusion is drawn from environmental and economic perspectives. (I) Major Factors Influencing Environment The major factors influencing environment entered into analysis of economic gains and losses due to environmental impacts are noise, ecological landscape and water pollution etc. according to characteristics of the project and specific local environmental conditions: (II) Environmental economic losses produced before input of environmental 613      protection funds L 前 (1) Environmental economic losses caused by noise: L 前声 According to the characteristics of the project, the populations around the air kiosk, cooling tower and depots as well as the ground lines of entrance/exit depot will be influenced by noise to various extents. Thus the project mainly assesses the environmental economic losses caused to surrounding populations due to subway noise. The report has selected the assessment coefficiency for environmental and economic lossed caused by noise of rail transit in Germany to passengers adopted by Planco in 1992 in a similar case, i.e. RMB 1.2 yuan per 100 persons km. Suppose the average running speed of the train is 35km per hour(daily operational hour: 18 hours). As rail transit is a rapid means of transport, if the short interval between the trains is omitted, the trains running on the route can be seen as continuous, and the social populations around the noise source will receive constant impacts by the noise. And such people are influenced by the noise as if they travel by subway at 35km per hour for 18 years. It is estimated 10101 persons will be influenced by the noise of the project, and L 前声 is 27.87 million yuan per year. (2) Environmental economic losses(L 前水) caused by water pollution: If the sewage discharged by the project is directly discharged without being disposed, the receiving water body will be polluted, and environmental economic losses will be caused due to deterioration of water quality. Such environmental economic losses is approximately replaced by the sewage discharge expenses payable for discharge of sewage of the same water quality and quantity. According to the current charging standards and provisions of relevant department, in case the sewage produced by the project is directly discharged without being disposed, the construction unit will pay 310,000 yuan per year as the sewage discharge expenses. Thus L 前水 is 310,000 yuan per year. (3)Total environmental and economic losses(L 前 ) caused before input of environmental protection funds: Environmental and economic losses caused before input of environmental protection funds: L 前= L 前声+ L 前水=28.18 Million yuan per year (III) Investment on Environmental Protection K The investment on environmental protection of the project is 225419000 yuan, which will be amortized over 4.25 years. Thus K is 53039764 yuan. (IV)Environmental economic benefits(B 措) caused by investment on environmental protection: (1)Environmental economic benefits(B 措声) caused due to decrease in the number of people influenced by noise after noise control According to the prediction results for impacts on sound environment, the noise level 614      at the sensitive points along the project line is basically maintained at the level before project construction after noise and pollution prevention and control measures are taken, that is the project construction will not increase the noise level of various sensitive points. B 措声 is 27.87 million yuan per year. (1) Environmental economic benefits(B 措水) caused by control of water pollution: According to relevant provisions, the sewage of the project will be discharged after reaching standard through treatment. The sewage discharge fee in the amount of 50,000 yuan per year shall be paid after sewage treatment through calculation, and 310,000 yuan per year shall be paid before sewage treatment. Thus the environmental economic benefits produced through treatment of water pollution(B 措水 ) is 260,000 yuan per year. (1) Total environmental economic losses produced by investment on environmental protection(B 措): B 措= B 措声 + B 措房 + B 措水 =28.13 Million yuan per year (V) Environmental economic benefits caused by engineering environmental impacts(B 工): The extent of environmental pollution will be different in case road traffic instead of rail transit is adopted to meet the ever increasing demands for traffic by economic and social development along the route of the project in Zhengzhou City. (1)Comparison of Environmental Economic Losses due to Noise Pollution: To compare the environmental economic losses casued by noise due to two means of transport, the function of road traffic shall be the same as that of the means of transport of the project, and the travelling speed per hour is 35km per hour, with the daily operational period being 18 hours and the same quantity of passengers. Moreover, as road traffic is totally on the ground, the number of people influenced by noise on the two sides of the traffil route will be larger than that of subway, and is estimated to be 104,000. The populations along the road are influenced by noise as if they travel by road at the speed of 35km per hour for 18 hours. According to relevant data of Germany, the estimation coefficient for environmental economic losses caused by road traffic noise on the passengers is RMB 1.7 yuan per 100 persons km. The environmental economic losses caused by road traffic noise(L 路声) is 406.55 million yuan per year through calculation. The environmental economic benefits(B 工声) caused by noise pollution in the two ways is B 工声= L 路声- L 后声=406.55 Million yuan per year. (2)Comparison of Environmental Economic Losses due to Atmospheric Pollution: 615      As rail transit utilizes power as energy, it produces less atmospheric pollution, thus the environmental economic losses caused by its atmospheric pollution is approximately 0. According to the conclusion of atmospheric environmental impact assessment, the emission of automobile exhaust will be reduced due to project construction. The environmental economic losses due to road atmospheric pollution is estimated according to the environmental economic losses caused by the road traffic exhaust on passengers in Germany, that is RMB 0.2 yuan per 100 persons km. B 工气=47.83 Million yuan per Year. (3)Total environmental economic benefits(B 工) due to engineering environmental impacts: B 工= B 工声 + B 工气 =454.38 Million yuan Per Year (VI) Analysis of Economic Gains and Losses due to Environmental Impacts: (1) In case B 总 is larger than 0, it shows the environmental impacts of the project are mainly beneficial. Net benefits from envrionemental protection investment B 总 =(B 措 -K)+B 工 -L 前 =397,610,000 yuan per year. (2) Environmental protection investment efficiency E 总=(B 措+B 工-L 前)/K=8.01 E 总>1, which shows that the environmental economic benefits of the project is larger than the environmental protection expenses, and the environmental protection investment effect is good. (3)Environmental protection investment/capital construction investment ratio: The environmental protection investment of the project is 225419000 yuan, and the estimated total investment of the project is 197699790000 yuan, thus the environmental protection investment/capital construction investment is 1.14%, which is similar to that of the environmental protection investment of similar domestic project. Thus the environmental protection investment is rational. 11.8.3 Conclusion: The completion and operation of the project will positively promote social economy and urban environment in areas along the routes of the project. The environmental economic losses caused by project construction will be controlled within a small scope after several environmental protection measures are taken. Project construction will produce significant social benefits and environmental benefits, which complies with the principle of simultaneous growth of economic benefits, social benefits and environmental benefits. 616      11.9 Environmental Reporting System The construction unit, environmental supervisory unit and environmental monitoring unit shall report progress of environmental protection project regularly, existing problems and effect of environmental protection measures etc. during project implementation, and the owner shall report the major problems to local environmental protection bureau regularly. 617      12 Conclusions and suggestions 12.1 Environmental status assessment 12.1.1 Acoustic environment There are 44 environmental protection objectives in the assessment scope, including 42 centralized residential buildings, one library and one religious venue. 44 ones among these sensitive points are affected by noise of ventilation system, and there is any sensitive spot in car depot and parking lot. Among these sensitive points, 20 ones execute Category 4a Standard, 24 ones execute Category 1 Standard. 12.1.2 Vibration environment There are 161 environmental protection objectives in the assessment scope, including 3 schools, 8 hospitals, 4 cultural relics sites under protection and 2 religious venues. environmental vibration VLz10 value of sensitive points along the line is 50.1～ 68.5dB in the day and 47.3～64.5dB dB at night, meeting corresponding standard limit value requirements of GB10070-88 Standard of Vibration in Urban Area Environment. 12.1.3 Water environment (I) Surface water The line underneath passes through Jinshui River, Xiong’er River, Qili River and Chaohe River in the form of tunnel (shield construction), and parking lot is located at southern bank of Jialu River. In 2012, surface water quality of Yellow River basin under administration of Zhengzhou City was good and in conformity with Level III standard. Surface water of Huaihe River basin under municipal administration was seriously polluted, of which Jialu River was seriously polluted, Shuangji River was moderately polluted, and Yinghe River was mildly polluted; one of 12 monitoring sections conformed to Level II standard, one conformed to Level III standard, two conformed to Level IV standard, and other eight ones were poor Level V, accounting for 8.3%, 8.3%, 16.7% and 66.7% respectively; main pollutants affecting river water quality were ammonia nitrogen, chemical oxygen demand and permanganate index. Main environmental protection objectives: Jinshui River, Xiong’er River, Qili River, Chaohe River and Jialu River. (II) Ground water 618      Ground water type of areas along the line mainly includes perched water, Quaternary system’s pore water among loose rock and fissure water of bedrock. According to the investigation, areas along the line take tap water as water source, In 2012, water quality by comprehensive evaluation for underground water environmental quality in Zhengzhou city area was good (Level I), water quality basically remained stable, and 7 points all reached underground water Level III standard. 12.1.4 Ecological environment This project is located at Zhengzhou urban area, the areas passed by this project take human activities as the core, there are row upon row of office buildings, stores, residential buildings and Party and government organizations, which is artificial ecosystem based on urban structure; areas around Jialu river parking lot, Boxue road Station and Hanghai east Station are mainly farmland and wasteland, and ecosystem type is farmland ecosystem, areas around car depot are mainly forestland, and ecosystem type is forestland ecosystem. There is no nature reserve, scenic spot or forest park in the assessment scope, and there are few farmlands only near car depot,and there are few forestland near parking lot. 12.1.5 Electromagnetic environment Cable television receiving systems are basically installed in households along the line, and networking rate of cable television can reach 90%. Only few rural residents still adopt open-type television receiving mode due to economic reason,there are any sensitive spot around Boxue road Main Transformer Station. Current electromagnetic environment around requested main transformer station meets standard requirements. 12.1.6 Ambient air Ambient air quality of Zhengzhou city area in 2012 reached Level III standard; ambient air quality of four county-level cities and one county including Xinmi City, Xinzheng City, Xingyang City, Dengfeng City and Zhongmu County reached Level II standard, and that of Shangjie District reached Level III standard. Primary pollutants of urban ambient air are inhalable particle except sulfur dioxide in Xingyang City and Shangjie District. Days of good ambient air quality in Zhengzhou city area in 2012 were 319 with rate of reaching the standard being 87.2%, days of good ambient air quality in four county-level cities, one county and one district under municipal administration were 312-345 with rate of reaching the standard being above 85%. Ambient air in Zhengzhou city area remained basically unchanged than 2011 in terms of pollution level. There was no acid rain. 619      12.1.7 Social environment At the end of 2011, built-up area of Zhengzhou city proper was 354.7km2, total population of Zhengzhou was 8,857,000, The urban center is highly populated, which brings tremendous pressure to the city center’s traffic. And there are defects in the existing road traffic system, reflecting the contradiction between traffic supply and demand more prominently, thus traffic paralysis caused by congestion in the core city zone may occur at any time. It’s predicted that the annual passenger traffic volume of public transport in 2015 will increase to 1.6 billion person-times from the number of 0.65 billion in 2007, with an average annual growth rate of 10.5%, and the number will reach up to 2.13 billion person-times in recent years (in 2020). Preservation buildings of cultural relics along the line include: separately of Memorial Tower for February 7th Strike, Zhengzhou Shang Dynasty Relics, Zhengzhou Confucius Temple. in which the distance of line to Memorial Tower for February 7th Strike body is only 3m,and in which the distance of line to Zhengzhou Shang Dynasty Relics is only 6m. 12.2 Environment impact assessment and measures of environment protection 12.2.1 Sound environment (I) Construction period The report indicates: in earthwork construction phase, the construction noises at locations 60m from construction boundary at day time and 350m at nigh time can meet the standard requirements; in foundation construction phase, the construction noises at locations 60m from construction boundary at day time can meet the standard requirements and the pile driving works must not be done at night time; in structure construction phase, the construction noises at locations 150m from construction boundary at day time and 350m at nigh time can meet the standard requirements.

The environment vibration of 6 sensitive spots exceeds the standard requirements, in which there are 1 sensitive spots with the vibration level exceeding the standard value at daytime with the over-limit amount of0～2.7dB, 6 sensitive spots with then noise level exceeding the standard value at nighttime with the over-limit amount of 0.1～5.7dB; and the over-limit rate is up to3.7％. The maximum speed response values of 3 cultural relics along the line including Zhengzhou Memorial Tower for February 7th Strike , Zhengzhou Confucius Temple and Shanhaimomuduha Tomb exceed the standard requirement, with the over-limit amounts separately of 1.18mm/s、0.96mm/s and1.57mm/s. The indoor secondary structure noises in 38 sensitive buildings within 10m range from right above of project underground section to outer rail centerline are in the range of 38.7~56.2dB. In reference to standard reference limit of “42dB(A)”, there are total 32sensitive spots affected by secondary structure noise due to subway vibration with the over-limit amount of 0.1~14.2dB The indoor secondary structure noises in 38 sensitive buildings within 10m range from right above of project underground section to outer rail centerline are in the range of 38.7~56.2dB dB dB. In reference to standard reference limit of “42dB(A)”, there are total 32sensitive spots affected by secondary structure noise due to subway vibration with the over-limit amount of 0.5~14.2dB. For reasonable planning of land use along the line, predict the vibration pollution 622      during operation period of rail transit; suggest as follows: ① According to the regulations in Subway Design Specification (GB50157-2003) and vibration protection distance of this report, the protection distance of buildings at both sides of underground line in areas of “mixing area, CBD”, “industrial concentration area” and “both sides of traffic arterial road” specified in GB10070-88 Standard of Vibration in Urban Area Environment is 25m; the protection distance of buildings at both sides of underground line in “residential and culture education area” area is 38m. ② Scientifically plan the layout of buildings to arrange the first row buildings near the vibration sources as vibration non-sensitive building such as commercial and office building. ③ In combination with the modification of old town, firstly demolish the residential houses near the vibration source, and, in combination with the greening design and re-arrangement of buildings, reserve the vibration prevention distance for newly developed buildings so as to ensure the impact on sensitive buildings within allowable range of standard. 12.2.3 Water environment (I) Surface water The domestic sewage, muddy water and other production wastewater generated from construction stations, car depot and other sites are reused or drained into urban pipeline network after treatment of sedimentation tank, and will not affect the surface water and underground water environment. The domestic sewage, muddy water and other production wastewater generated from construction stations, car depot and other sites are reused or drained into urban pipeline network after treatment of sedimentation tank, and will not affect the surface water and underground water environment. (II) Ground water The report indicates: since the groundwater depth of project along-line and nearby areas is normally deep and the bottom groundwater depths of along-line stations of this project are larger than the buried depth of groundwater level in this region, the dewatering works shall be done for open-cut or cover-cut construction methods. In addition, seven sections including Xinliu Road Station end siding area, Xinlongpu Station end siding area, Huanghe Road Station end siding area, Taikang Station end siding area, East Street Station end siding area, Tongtai Road Station end siding area and Zhongxing Road Station end siding area adopt open-cut construction method, which requires dewatering during tunnel construction; the other underground sections adopt shield construction method without need of dewatering. The report predicts that, under the conditions of water proof measures, the possible ground settlements mainly concentrate in 10-20m range around the station foundation pit and the settlement amount around the station is normally no more than 30mm. The report indicates that the underground water types of regions along the line of project are mainly of perched ground water, quaternary loose rock type hole water and bedrock crevice water, in which the quaternary loose rock type hole water is the 623      priority. The underground water is mainly supplied from surface waters (including Jinshui River, Xionger River, Chaohe River) with less impact from artificial exploitation. In normal water season and low water season, the underground water feeds surface water and the underwater drains to the surface water; while in flood season, the surface water level rises and the surface water feeds the underground water. The impact of this project construction on underground water feeding is very small. The measures provide in the report are as follows: Construct the concrete diaphragm wall before the construction of underground station and section to block off the underground water and use as the retaining structure. Then based on the proper anti-seepage works, lay out the blank tubing under the channel at both sides of tunnel to collect the residual water to the ground surface; set up the sedimentation basin on the ground; the water is discharged to municipal sewage pipe network and then sewage treatment plant after sedimentation in the basin. 12.2.4 Ecological environmen (1) The project does not involve any ecological sensitive area such as natural reserves, scenic spot and basic farmland conservation area. (2) After construction and operation of this project, it will enhance the connectivity of all function block landscapes along the line, keep the smooth input/out operation between the function blocks, ensure the high efficiency operation of city, enhance the stability of urban landscape ecological system and ensure the healthy development of city. (3) According to the landscape aesthetics analysis and analog survey analysis, if fully considered the unique historic city property of Zhengzhou city and land use pattern and adopted the design with blending method and hidden method, it can keep the coordination of ground buildings such as station entrance/exit and ventilation pavilions with ambient environment. (4) The construction of rail transit has remarkable advantages in saving of land resource and energy, and in favor for integration and modification of Zhengzhou land resources, relief of regional land utilization pressure and improvement of land utilization efficiency. 12.2.5 Electromagnetic environmen The report indicates: The ground line train traveling may impose certain impact on the TV user with antenna to receive signal, but most of the channels can be normally displayed. Since the cable TV connection rates at sensitive spots of this project are high,and there are any sensitive spot around Boxue road main substations,so there has no impact. By analogy monitoring, after construction and put into service of Boxue Road main substation and Erqi Square switching station, the generated power frequency electric field and magnetic field comply with the limits of power frequency electric field of 4kV/m and power frequency magnetic field of 0.1mT recommended in HJ453-2008 Technical Guidelines for Environment Impact - Urban Rail Transit. 624      It recommends properly laying out the main substations and reasonably planning the lands around the main substations so as to make the fence of substations away from the residential area as possible. The least distance from the residential area shall be more than 15m. 12.2.6 Ambient air The air pollutant emission during construction period mainly comes from the raise dust generated by construction excavation, material placing, earthwork transport and construction materials such as yellow sand and cement,and yellow sand and cement is the main factor. In addition,the exhaust pollutants emission is low with minor air environment impact. The exhaust gas during construction period mainly includes the tail gas emitted by construction machines and flying dust generated during construction field operation and transportation, in which the flying dust is the main influential factor for atmospheric pollution during construction period. There is very few tail gas emitted by the machinery during construction period with little impact on the environment. The flying dust during construction period will impose certain impacts on the residents around the construction sites and transportation roads. The flying dust amount is closely related to the construction mode, natural conditions of construction site and construction management. Since the construction sections in this project are short and the excavated earth volume during construction period are small, it can relieve the adverse impact on atmospheric environment by the construction by strengthening the management during construction period and taking effective dust suppressing measures. According to the prediction: during initial period of operation, the odors emitted by the pavilions will be serious due to the mildews in underground dark and humid environment and also the impact of decoration materials; and there is evident odor within 15m range. The measures provide in the report are as follows: in this design program, 8 sensitive spots at Dongfeng Road Station, Nongye Road Station, Huanghe Road Station and Shuncheng Street Station conflict with the land use of ventilation pavilion or the distance is less than 10m, and they are planned to be demolished; in addition, the distance from ventilation pavilions at Shuncheng Street Station and Taikang Road Station to the sensitive spot is less than 15m, and the odors emitted from ventilation pavilion will impact the resident livings to some extent; in combination with the control measures listed in noise topic, the environment assessment suggests to adjust the locations of 8 ventilation pavilions with the distance of less than 15m from sensitive spots. To effectively relieve the odor impact, it is necessary to plant arbors around ventilation pavilion and make the outlet opposite to the sensitive spots such as residential building. 12.2.7 Solid wastes The report indicates the solid wastes of this project during construction period are mainly of engineering spoils, construction wastes and domestic wastes of construction 625      personnel. Failing to timely clear and handle will impose adverse impacts on the environment within construction range. The total amount of solid wastes of the project after operation is about 860 - 1370t/a. The production wastes mainly include the metal filings, waste scraps and waste batteries from car overhaul and wastewater treatment in car depot and comprehensive base, and the sludge and waste oil mud from sewage treatment plant. The main measures provided in the report include: All spoils are transported to the spoil grounds specified by urban management department for landfill treatment. The construction unit shall assign managerial personnel to carry out site management of the disposal of spoils and rubbish. The vehicles transporting spoils shall be equipped with sealed cover, and shall run according to the prescribed time, site and routes. The engineering spoils and building wastes shall be handed over to Zhengzhou Municipal Urban Management Bureau Solid Waste Division for uniform and proper disposal. Reasonably arrange the rubbish bin and collect the domestic wastes in the stations and carriages; transport the domestic wastes collected along the subway line and car depots to the environmental sanitation department for uniform disposal; the production solid wastes such as metal chips and waste scraps shall be recycled; the waste batteries shall be properly kept according to hazard waster regulations and transported by the manufacturer back to the plant for disposal; the sludge and domestic wastes from sewage treatment plant shall be transported together to the municipal solid waste landfill for disposal. 12.2.8 Social environment (I) Impact assessment of the project on social environment Whether in construction period or operation period, this project will affect the livings of Zhengzhou citizens in different degrees and from various aspects. The positive effects lie in that the project construction will provide Zhengzhou people a more rapid, convenient and environment protection public transit facility and Zhengzhou rail transit line 3 during operation period will become a more convenient, safe, comfortable and economic communication mean for the residents along the line; at same time, the project construction works and enclosure will inevitably bring forward adverse impact on the people along the line; however the adverse impact is controllable and temporary as long as implemented related relief measures in the report. The positive effects also include followings: the barrier free access benefits the traveling of disables; the increase of female toilet proportion enhances the female social position and living convenience; the reasonable ticket fare is in favor of the low-incoming group and equivalent to increase of economic income; the rail transit line 3 improves the urban traffic after operation and brings forward favorable impact on land utilization change an therefore promote the implementation of development construction and planning of city. The adverse impacts are mainly in construction period and include followings: the station enclosure impacts the local urban traffic; station construction enclosure imposes temporary impact on incoming of surrounding merchants; the construction 626      enclosure leads to inconvenient livings of nearby residents and increases their traveling time; noise and vibration disturbance due to construction machinery operation, construction raise dust, sewage, muddy water, deposition and transport of construction garbage and construction materials will affect the living quality of residents; the ground settlement and vibration affect the ground building stability during construction period. 12.2.8.1 Improvement measures for negative effects The specific protection measures for impact on urban traffic environment impact by the project are as follows: the traffic dispersion program for 3# line complies with the principle of “Compensate a road for each road Occupation”. During construction of stations in Huiji District including Xinliu Road Station, Shamen Road Station and Xinglongpu Road Station, since the vehicle flow and passenger flow is small and the road is wide, the construction enclosure duration in traffic dispersion measures are short and the construction can be completed in short term. So its traffic impact is not much in long term. For Dongfeng Road Station, Nongye Road Station and Huanghe Road Station of Nanyang Road and Taikang Road Station of Minggong Road, the vehicle and passenger flows are dense and the roads are crowed. To avoid large impact of traffic by enclosure during construction period, the construction enclosure range in traffic dispersion measures are small and the enclosure duration is long. It is preferable to use cover-excavation construction method for Taikang Road. For the impact on urban traffic by construction of Zhengzhou Rail Transit Line 3, except preparation of reasonable traffic dispersion program, it shall set up real time notice to provide the enclosure information to the residents and it shall inform the residents in advance if any necessary bypassing. For 201 merchants to be demolished along the line, compensate according to market price and provide 6 months close-down compensation reward. For 858 store employees, offer one-off 6 months minimum wage compensation for actual employees registered in business license. For the construction of stations in old district with dense residents, enterprises and public service unit, it shall reduce the construction noise and vibration impact by setting up construction enclosure, properly arranging the machinery in construction site, prohibiting pile driving operation at night time, and relieve the impact of raise dust by sprinkling and dedusting in construction site and covering the construction materials. 12.2.8.2 Improvement measures for positive effects (1) Design of station wheelchair access To ensure safe, convenient and rapid utilization of the traffic facilities by the people with various demands such as blind people, disabilities, office staff and the people with many luggage, Zhengzhou rail transit 3 line stations design the wheelchair access according to Code of Accessibility Design, such as sidewalk for the blind, accessible elevator and staircase, which can separately meet the requirements for the disables and the blind to ride the rail transit. The staircase provides a good luggage transport access for the people carrying many luggages. The design principle is to ensure 627      minimize transfer line and save the traveling time of office staff. (2) Consideration of proportion of men and women toilet positions According to related social survey and social feedback reports, due to different physiological characteristics of male and female, the time consumption in toilet for male and female has remarkable difference. According to the statistics, the average time consumption in toilet of male is only 1/5 of that of the female. Based on above reasons, improvement of toilet position design in 3 line stations to increase the toilet position numbers of the male and the female with the female toilet position increment larger than that for the male can reduce or avoid the lining-up for toilet of the female (the female toilet position increase will considerably shorten the lining-up time of the female) so that it can not only facilitate the female, but also enhance the satisfaction of the male waiting for the female. (3) Reasonable consideration of low-incoming group during determination of ticket fare In entire social group in Zhengzhou city, the low-incoming group is a special group accounting for a large portion. The definition of ticket fare for Zhengzhou rail transit 3 line shall consider the traffic of low-incoming group in Zhengzhou city. It shall prepare reasonable ticket fare satisfying most of people for different hierarchies and different incoming levels of low-incoming groups, and positively affect the society. 12.2.9Material and culture resources There are four physical cultural heritages identified in this project, separately of Memorial Tower for February 7th Strike, Zhengzhou Shang Dynasty Relics, Zhengzhou Confucius Temple and Penggong Temple, in which the distance of line to Memorial Tower for February 7th Strike body is only 3m; there is no ground buildings such as entrance, ventilation pavilion or cooling tower in protection range in protection range and there is an entrance in construction control zone; the line passes through underground of Shang Dynasty Ruins and there is no ground building in its protection range and construction control range; the line passes through underground the construction control range of Zhengzhou Confucius Temple without any ground building; the Penggong Temple is located at west gate of People’s Park and the line passes through underground with far distance. The protection measures provide in the assessment are as follows: carry out pre-reinforcement before construction at Memorial Tower for February 7th Strike; adopt shelter pile measures during 3# line shield construction and mount steel spring floating slabs in 50m range at both sides of protection range, and intensify the settlement monitoring during construction period; during design of stations near the cultural relics including Erqi Square Station, Chengdong Road Station and Taikang Road Station, the design of entrances, ventilation pavilions and cooling towers shall be kept uniform separately with People’s Park Shang Dynasty Cultural Display Area and Jinshui River Waterfront Park landscape, Memorial Tower for February 7th Strike and Dehua Commercial Center and Shang Dynasty ruins landscape. Since Zhengzhou is one of national famous historical and cultural cities and listed in 628      eight ancient capital cities, the general style design for stations and ventilation pavilion of rapid rail transit of complete city shall have the visual image of city culture and coordinate with the heavy culture connotation of Zhengzhou. 12.3 Evaluation conclusion of cumulative impact The main cumulative impacts of 3# line during construction period mainly include: ① Shield construction soil from sectional construction of 2# line and construction spoils of complete 3# and 5# lines;② Impacts from concurrent construction of 3# and 5# lines on the surrounding areas of station such as traffic congestion, increased flying dust and traveling inconvenience; ③ Cumulative impact on own settlement of tower foundation due to the construction near February 7th Memorial Tower. The main cumulative impacts of 3# line during construction period mainly include: the same sensitive spot is subject to the impact of subway pavilion at both sides; the same sensitive spot is subject to the impact of vibrations from 2 subway lines nearby; interaction between urban bus rapid transit and rail transit after operation. Intensify of management methods during construction period, improve the selection of spoil ground and various environment protection measures during operation and decommission period, reasonably select the construction sites and arrange the construction time. Carry out the construction works around Erqi Tower according to approved Protection Program for Zhengzhou Rail Transit Project Passing through side of February 7th Memorial Tower, and intensify the monitoring measures during construction period; as a result, it can relieve the adverse impact on environment for concurrent construction of major projects. The cumulative noise impact during construction period can be relieved by reasonably adjusting the positions of pavilions and cooling towers, selecting low noise equipment and lengthen the silencer; the cumulative noise impact during operation period can be relieved by the vibration reduction measures such as adoption of steel spring floating slab. By in-depth design of BRT route, station position selection and departure intervals, it can make use of the advantages of both urban rapid transit and rail transit to set up 3D rapid public transit system. 12.4 Conclusion of analyses to alternative scheme This report highlights the comparison and selection of alternative scheme in line trend, station location as well as the comparison and selection of alternative scheme in underground interval and underground station construction scheme. (1) In the comparison and selection process, comprehensive comparison of line operation condition, construction hardness, civil work investment, passenger flow attraction and environmental impact have been taken into account. For the comparison selection of the line trend at the north of the North Ring, both schemes will down-traversing the existing road and have no conflict with the planning. But due to the influence of the Beijing-Guangzhou Railway at the west, the recommended scheme can attract more passengers. Furthermore, the plot at the northeast of Nanyang 629      Interchange is under reconstruction, which can reserve spaces for Line No.3. From the long-term planning point of view, the recommended scheme will go further north, down-traversing Lianyungang--Khorgos Expressway and Jialu River. Stations will be built in the planned Binhe Road intersection, Kaiyuan Road intersection and Dahe Road intersection. The Kaiyuan Road Station is a transfer station with subway Line No.2, so the transfer conditions are good. From the social impact point of view, the recommended scheme is relatively better. From the environmental impact point of view, the recommended scheme will not down-traversing existing housing estate, so the impact of vibration on residents is small. From the finance point of view, the recommended scheme is better due to the reducing of construction difficulty. To sum up, this report argues that the recommended scheme is relatively better. For the comparison selection of line scheme from Jinshui Road Station to Seven Feb. Square Station, while the positions of Jinshui Road Station and Seven Feb. Square Station are fixed at both ends of this line, the scheme along Minggong Road is the straighter and the demolition amount is small. However this scheme is restricted by the Huigangxincheng under construction and the Memory Tower for “Feb. 7th”. Vibration and secondary structural noise will affect them during the operation period. The detour scheme at the west of Minggong Road is slightly far away from the Memory Tower for “Feb. 7th”, but the vibration during the operation period will still affect them. Furthermore, this line will down-traversing seven buildings of 6 to 7 storeys at the north of Jiefang Road, and many low buildings of 1 to 2 storeys. The demolition amount is large, and the social impact is great. Besides, buildings in the old housing estate are of brick-concrete structure, and the vibration resistance ability is poor, so the vibration and secondary structural noise will have large influence on them. The engineering cost of demolition is large, too. Based on the above analysis, this report suggests the use of the recommended scheme, which is the Minggong Road scheme. For the comparison selection of line schemes down-traversing the planed National Highway No.107 Interchange, the recommend scheme is straight, its influence on existing railway is small, and the engineering cost is low. There will be interchange at this intersection, which requires the proper consideration of the positions of piers during the design process to connect with Line No.3. The alternative scheme is curved and obliquely-traversing the high-speed rail, so the engineering cost is high. Therefore, this report suggests the use of the recommended scheme. (2) In the comparison and selection of key stations, Jinshui Road is the trunk road for east-west traffic of Zhengzhou. The passenger flow is large and it is very important. Therefore, the impact on the traffic of Jinshui Road during the construction and operation periods shall be considered in priority when selecting the position of station on Jinshui road. The recommended scheme has certain advantages both in passenger service and traffic influence. Its function is better. Although there are certain risks during the construction process and the engineering investment is slightly higher, certain engineering measures can be taken to guarantee the construction safety. Scheme II is recommended for this section with the principle of people oriented and function priority. (3) The interval construction scheme conducts the comparison and selection to the shield method and the mining method. It can be seen from the engineering technology 630      that the shield method is relatively easy in passing through the geological fault, mature in construction method, high in automaticity and quick in construction, therefore it is smaller in construction hardness than the mining method, and is flexible in construction period, easy to control; The shield method is relatively easy in passing through the geological fault, mature in construction. Relatively in controlling the land subsidence and small in construction risk; From the aspect of impact to social environment and natural environment, the shield method construction is relatively good in controlling buildings around and the ground deformation, quick in construction, good in construction environment without any impact to environments such as underground water; In addition, the construction of this interval gives priority to the shield method taking the geologic characteristics of Zhengzhou into account. (4) The station construction scheme conducts the comparison and selection to open deep excavation, covered excavation and subsurface excavation. The open deep excavation has larger environmental impact of ground traffic, land use, noise and dust than the covered excavation and subsurface excavation, however when the ground has adequate construction yard, the road can be occupied for long time by dispersing the traffic and the underground pipelines possess the modification and correction condition, construction method of the underground station should firstly consider the open excavation order method for its simplicity, quick speed, economy and safety. The open deep excavation has obvious advantages comparing to the subsurface excavation in construction safety, construction difficulty, and construction period, quality of structure waterproof and cost of civil work. According to the environmental conditions, the traffic dispersing conditions, the underground pipeline modification and correction requirement, the geological conditions, the buried depth of the station, and other factors, and by drawing on the successful experience of domestic subway construction, it is suggested that the underground stations of this line shall be constructed by firstly selecting the open cut method. The segmented inverted edge construction method or open cut + local cover-excavation method can be adopted for traffic trunks which need dispersing the traffic or crossing intersections. The geology along Line No.3 is mainly alluvial plain, the groundwater level is high and the geology is poor. The construction difficulty is really large for the station of more than 20 m in width. Therefore, the undermining method is generally not considered for the main structure of the station. Therefore, the open cut method or cover-excavation method will be used for stations on rail transit Line No.3 according to the recommendation of surrounding environment. Jinshui Road is the trunk road for the east-west traffic in Zhengzhou. The adoption of cover-excavation method will have small impact on ground traffic. All other stations are constructed by the open cut method. 12.5 Conclusion on Environmental Risk Analysis (1) Risk during construction period mainly occurs during digging of base pit or interval tunnel. Improper selection of construction methods tends to cause uneven settlement, ground collapse or bulging; Accidents such as collapse, roof fall, sand gushing water gushing, and water transmission etc. tend to happened during construction due to influences by multiple factors such as geological and hydrological factors etc.; Improper selection of construction methods and retaining program will 631      cause breakage of adjacent underground pipelines or cracking, leaning or even collapse of surrounding constructions. Major risk source during operational period: The major risks and accidents during operational period come from social hazards such as arson or terrorist attack etc., and the accidents due to improper operation by staff and mechanical failure etc.. The aforesaid accidents have not only caused huge economic losses and tend to cause personal casualty and significant social influences. (2) The stratum are mainly earth with medium within the depth of 30m under the line(K0+0.000~K25+200) and underground stations(Xinliu Road Station, Shamen Road Station, Xinglongpu Road Station, Dongfeng Road Station, Nongye Road Station, Huanghe Road Station, Jinshui Road Station, Taikang Road Station, Er’qi Square Station, Shuncheng Street Station, Dongdajie Station, Chengdong Road Station, Future Avenue Station, South Fengtai Road Station, Zhongzhou Avenue Station, Tongtai Road Station, East Huanghe Road Station, East Nongye Road Station, Zhongxing Road Station, Boxue Road Station, East Hanghai Road Station), the characteristic are high compressibility, low strength and poor stability. The area belongs to area with medium risk level of geological disaster. The major categories of geological disaster are ground collapse, ground fissure, ground precipitation and uneven ground settlement. Meanwhile, the subway station is constructed by means of opening digging and cover digging, and extraction and drainage of a large quantity of underground water in base pit tends to cause sudden decrease in underground water level and drifting sand, regional ground settlement and collapse, and deformation and cracking etc. of surrounding buildings. As No.3 subway line runs across the bridge piles such as Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line and Shiwu highspeed railway line etc,, and tends to cause settlement and deformation of the aforesaid buildings or structures, and many overturn the structures and endanger safety in serious cases. (3) Carry out pre-construction investigation and design of risk sources during construction period, and establish environmental safety classification system for construction period, adopt new construction techniques and technology, strengthen monitoring and measurement during construction, establish environmental safety technical management system for subway construction, and formulate emergency measures to lower risk. As No.3 subway line runs across the bridge piles such as Beihuan and Nanyang Road approach bridge, Nanyang and Jinshui Road approach bridge, Zhongzhou Road and Shangdu Road approach bridge, the elevated bridge of Longhai railway line and Shiwu highspeed railway line etc, and various of municipal fundamental pipes,, it is necessary to carry out strict monitoring and monitoring measures against structural deformation of the tunnel, ground settlement, structure deformation and settlement etc.. Adopt earth pressure balance shield and select optimal construction parameters to ensure stable cutting face; strength the synchronous grouting and necessary supplement measures to control the settlement of structures, meanwhile it is necessary to take ground reinforcement measures. Supporting and water-stopping measures such as diaphragm wall, drilling hole pile plus water seal curtain etc. have been adopted for subway stations constructed by means of open digging and semi-cover digging of the project to control drainage and 632      extraction of underground water and prevent ground settlement. Meanwhile, observe settlement of the surrounding buildings of the base pit, and monitor the underground water level etc.. (4)Take risk management measures such as strengthening publicity and education for passengers and staffs; Equipping advanced equipment and testing system; Establishing monitoring and alarming system; Formulating emergency program; Carrying out mimic exercise; strengthening emergent evacuation of passengers after occurrence of accident to lower the possibility of risk and personal and property losses caused thereby; 12.6 Conclusion on Resettlement (1) The project will have social impacts related to the need for land acquisition and  demolition  of  a  number  of  structures  like  houses  or  enterprises.  Based  on  the  survey,  about  767  people  from  239  families  will  be  affected  by  the  acquisition  of  55.3  ha  of  land,  including  52.4  ha  of  collectively  owned  land;  about  1,308  people  from 449 families will be affected by the demolition of 35,347 m2 of private houses;  and about 1,026 employees from 264 enterprises, institutes and small shops will be  affected by the demolition of 66,313 m2 of structures.  (2) Certain economic losses will be caused on the aforesaid units, shops and individuals due to land requisition and resettlement for the project, which will influence their life and employment as well. The major environmental impact caused during resettlement is the construction garbage and flying dust caused by house dismantlement. Certain impacts will be caused on vegetation due to resettlement, which will also cause noise as well. (3) The major measures to reduce impacts on immigration and resettlement in the report are as follows: Immigration and Resettlement Office of Zhengzhou Rail Transit Group has held joint conference attended by various consultancy units and designing units during project planning and design to adjust and optimize the project design program and reduce the quantity of resettlement and land requisition. Make out compensation and reward program for the personal households with resettled houses, the families influenced by land requisition, and the enterprises, units and shops influenced by resettlement, and the employees of the shops influenced during resettlement. Feedback mechanism for public opinion has been formulated to lower the social impacts caused by resettlement. The environmental impacts caused by resettlement are reduced through rational arrangement of construction plan and traffic organization and design, water sprinkling to reduce dust and strengthening vibration and noise reduction measures during project construction. 12.7 Conclusions on Public Participation: (1) Most of the public along the project line support construction of phase I project of RTL#3, Zhengzhou, and hold that the project construction will promote traffic and 633      economy of Zhengzhou, and expect earlier completion of the project. (2) Through the public participation investigation, the citizens along the line have known about the project profile, the routing and the station locations proposed, the environmental problems that will arise from the project and the proposed mitigation measures to these. (3) The public along the line understand and accept the environmental measures to deal with the impact basically, and expect to strengthen construction management and strictly implement the proposed environmental protection measures during the construction period in the report to avoid interference with the people due to traffic jam, sewage, slurry, construction dust and noise. (4) The public hope the relevant parties to improve the transparency of the resettlement policies, strictly act on laws and rules, and inform the households to be resettled as early as possible to enable them to make sufficient preparation. (5) Strictly take measures, and prevent ground settlement; strengthen monitoring on ground settlement during construction; formulate emergency plan with a certain aim. (6) The opinions obtained through public survey are beneficial for the relevant construction, design, building, operation and management units and departments to pay more attention to the adverse influences the project may cause, and take comprehensive measures and win the understanding and support by the public along the project line so as to embody the social, economic and environmental benefits brought about by the project. 12.8 Conclusion on Comprehensive Assessment: Construction of Phase I Project of Zhengzhou Rail Transit Line 3 will greatly alleviate traffic congestion in central urban area, contribute to improvement of the integral traffic structure of Zhengzhou and urban renewal and development, and possess remarkable social benefit, economic benefit and environmental benefit. As one type of advanced urban rapid transit system, rail transit is electric-driven without environmental problems such as atmospheric pollution along the Line, and it can reduce automobile exhaust due to replacement of some buses and improve urban atmospheric environment, so to speak rail transit is green transportation means. Since urban center areas are located along the Line with centralized residential buildings and important environmental sensitive points such as historical and cultural sites under government protection and schools, project construction and train operation during operational period will produce certain degree and scope of noise, vibration and waste water, affecting social environmental elements such as urban traffic, resident income and residents’ lives to some extent. Since the design takes corresponding control measures, and this report also puts forward targeted prevention measures and suggestions, as long as these environmental protection measures and main construction realize “Three Simultaneous” (simultaneous design, simultaneous construction and simultaneous putting into operation), at the same time, strengthen monitoring management, the influence of this project on the environment can be controlled and mitigated. 634      To sum up, this project conforms to the principle of coordinating and unifying social benefit, economic benefit and environmental benefit, so project construction is feasible in terms of environmental protection. 635
