Xining is the capital of Qinghai Province. With great support of provincial Development and Reform Commission, Xining started at the end of 2006 preparation of a World Bank loan funded project, i.e. Xining Flood and Watershed Management Project, the first standalone World Bank loan project of Qinghai Province, and the project was officially put into implementation at the end of 2009. Xining Flood and Watershed Management Project was implemented in one city and three counties (i.e., Xining City, Datong County, Huangyuan County and Huangzhong County) and involved 6 components such as flood control and management, sewage collection, participatory small watershed management, institutional capacity building, resettlement and environmental management and project management, as shown in the following table (Table 1.1-1). The above mentioned project has been successfully accomplished. 6 Table 1.1-1 Activities included in Xining Flood and Watershed Management Project No. Components Activities Description of Activities Expected Results of Construction Gully Improvement: Flood control embankment of 53.617 km in total along Beichuan Gully mouth River, Nanchuan River and mainstream Huangshui River; gully Flood control standard upgraded to 1 in 100 years for improvement and mouth section flood control construction of 35.006km in total Xining, 1 in 50 years for the 3 counties and 1 in 30 years landscaping and Flood Control and for 28 gullies, and construction and development of 3 recreation for the improved gullies. 1 recreation area 2 Management areas totaling 2.62 km in Xining City. development Information collection system, computer network system, Flood control, early warning and protection capabilities Development of flood information processing system and early warning information of Xining greatly upgraded and losses of lives and early warning system disclosure system property minimalized.

Implementation of the project not only accomplished to a great extend a complete flood control system and a small watershed management system, which was not possible before the project due to financial limitation of Xining City, it also played an important role in bringing in new project concepts, staff training and capacity building, and therefore laid a good foundation to guarantee future development and implementation of other projects in Xining. Thanks to national and the World Bank funded projects, a fundamental flood control system has been formed in Xining and a waste water collection pipe network has been installed in the main urban area of the city. However, water quality of the rivers in the city is still not up to standard and water quality at Xiaoxiakou control cross-section is poor, characterized by serious pollution and higher sediment content. Currently, the main environmental problem with Xining can be summarized as ‘dirty water and turbid water ’, which can be embodied in the following four aspects: (1) Water pollution: direct wastewater discharge into river still exist in the suburb of Xining; (2) Lack of environmental water: seasonal water shortage of rivers in Xining results in reduced overall assimilative capacity of the rivers and reuse of reclaimed water is still inadequate; (3) Solid waste dumping into river, improper filling of river floodplain for land reclaimation, inadequate urban service infrastructure and poor living environment are problems found in some riverine areas of Xining City; (4) River sediment problem: gravity erosion of the gullies in Xining is serious. Without adequate engineering facilities, rainwater washes sediment directly into rivers in rainy days. In the gully head areas, solid waste dumping and direct sewage discharge make the local environment lousy and unpleasant. At the same time, water shortage is a serious challenge to Xining to cope with overall growth of future water demands, since its water resources utilization ratio is now 51.4% and available water resources are scarce. Based on the current situation, the newly approved Xining City plan clearly 8 states its objectives as ‘reaching waste water treatment ratio of above 90%,with a treatment capacity of 440 thousand m3/day; reaching reclaimed water reuse ratio of above 30%, with a total reclaimed water amount of 164 thousand m3/day; fully implementing river channel and river bank improvement; strengthening Huangshui River eco-environmental development and further upgrading vegetation coverage ratio; continuing to implement water and soil conservation and ecological recovery projects in watersheds of Xining City so as to reduce discharge of sediment and wastewater into the rivers’. In order to realize the above objectives and address the problems of serious water pollution and water shortage, Xining City deems it appropriate and necessary to propose use of the World Bank loan to support an integrated environmental improvement project consisting of components of rainwater and sewage collection pipelines, integrated river bank environment improvement, reuse of reclaimed water, and integrated gully improvement. The proposed project has been listed by NDRC as the World Bank loan pipeline project. In March 2013, Huangshui River Basin (Xining Section) Integrated Management Committee entrusted Environmental Quality Impact Assessment and Research Center of Lanzhou University to conduct environmental impact assessment of the proposed project. Following that, the task team of Lanzhou University conducted data collection and discussions on potential environmental issues relating to the proposed project, as well as field surveys and monitoring to the planned project sites, with cooperation and support of relevant local departments, and thereby prepared the report Environmental Impact Assessment for the project. The task team expresses hereby its sincere gratitude to the Project Management Office and other relevant local departments for their great support and assistance it received in the preparation process of this report. 1.2 Project Components Qinghai Xining Water Environment Management Project consists of four components as listed in the following table and the shown in Figure 1.2-1.

The task team thus prepared a Social Assessment Report for the project and the main findings are summarized in the following sections. 4.5.1 Social Impact Assessment Based on systematic field surveys, the social assessment expert and his task team conducted prediction and adequate analysis of social impacts and benefits of the proposed project during its construction and operation periods, and summarized the main findings of social assessment. In accordance with results from a great amount of public consultation and participation activities, suggestions on strengthening positive impacts and mitigating negative impacts were also put forward to promote sustainable project development and safeguard interests of and benefits to the local people in the project area. Details of the findings and suggestions are shown in Table 4.-1 that follows. Table 4-1 Findings from Social Assessment and Suggestions Findings from Social No. Suggestions Assessment 1 ） Information dissemination prior to the construction should be well conducted, and section by section and phased construction should be adopted to minimize impacts on the enterprises and businesses along both sides of the roads.

Implementation of the proposed project will produce all-rounded, open to all and shared social benefits. Such social benefits will not only be apparent in the short run, but also sustainable in the long run to promote sound social development. In the process of project implementation, while paying attention to attaining project benefits, social risks that may accompany the project should not be neglected. If improperly handled, the activities involving sewage and/or reclaimed water pipe installation, connection and management and other constructions may cause negative impacts that undermine the project benefits or even cause negative impacts on realization of project objectives. To address these potential risks, relevant departments of Xining should have comprehensive consideration and adopt corresponding measures 41 to reduce such risks and ensure project benefits for sustainable project development. Together with the PMO, project owners, implementing entities and project design institute, the social assessment task team conducted thorough consultation and discussions on the social risks and prepared a feasible social action plan with details shown in the following table (Table 4-2). 42 Table 4-2 Social Risks of the Proposed Project and the Action Plan Project Components Project Risks Actions Timing of Action ① During construction, business of enterprises and ① Project unit committed to well conduct information dissemination prior shops along both sides of the to construction, and adopt phased and section by section construction roads and daily life of local method to reduce impacts on business of the enterprises and shops along ① Prior to and residents may be impacted and both sides of the roads.

When the project is put into operation after its completion, the driving vehicles will generate exhaust gas, dust nuisance, noise, etc., the operation of wastewater treatment and reclamation plant will generate noise and foul smell contaminating surrounding environment, and the operation of wastewater treatment and reclamation plant project will cause noise emission. In addition, the serious contamination of local area by sudden contamination accident needs to be considered. Therefore, in order to overall and timely grasp the trends of pollution along the project, learn about the environmental quality change of neighboring region, and serve the environmental management of project construction area, the environmental monitoring needs to be carried out for the construction project. The environmental monitoring plan is prepared for the purpose of supervising the implementation of each measure so as to adjust in a timely manner the environmental protection action plan, providing basis for the implementation time and implementation plan for environmental protection measures. The monitoring plan is prepared by predicting the main environmental impacts, road sections likely to exceed standard and indexes that might be exceeded (with focus placed on main sensitive receptors ). Implementation of the environmental monitoring plan will enable timely understanding of environmental quality of project area and will help in analyzing environmental impacts of project construction, so that corresponding mitigation measures can be taken to minimize environmental impacts caused by project construction, ensuring that negative impacts on people’s life or damage to natural ecological environment can be eliminated or mitigated. Environmental monitoring for the overall proposed project can be entrusted by Xining Municipal World Bank Project Office to a qualified institute, which will then take responsibilities for collecting and analyzing data and preparing environmental analysis report for submission to the entrusting party and, via the entrusting party, to the World Bank. See Table 5-1 for organizational responsibilities of monitoring plan for the project. Table 5-1 Organizational Responsibilities of Monitoring Plan Tasks Responsible Unit Local environmental monitoring station with Collection of monitoring data qualifications can be entrusted 45 Monitoring unit is responsible for collecting and Data analysis analyzing data Monitoring unit prepares the report based on Preparation of environmental report monitoring data collected Xining Municipal World Bank Project Office may entrust a unit to conduct the above tasks. According to the monitoring plan, the entrustee should consolidate and analyze the quarterly monitoring data, and prepare and submit environmental analysis report to the entrusting party for its submission to the World Bank. After its submission, the environmental analysis report shall be managed and filed by Xining World Bank Project Office, and will be used to Management Plan compile the overall environmental impact report during project implementation for the purpose of project completion acceptance. 5.2 Monitoring Agency It is recommended that management organization should entrust the local environmental monitoring station with qualifications to perform monitoring plan and undertake timely monitoring of environmental impacts of sudden contamination accident. On one hand, such arrangement can make use of advantages of the fully-staffed, well-equipped, existing environmental monitoring; on the other hand, it can save costs of investment in monitoring equipment and personnel for the management organization of the proposed project. The project management organization should sign monitoring contract for implementation period prior to commencement of construction, and sign monitoring contract for operation period prior to project delivery. 5.3 Environmental Monitoring Plan According to results of environmental impact prediction, the pollution sensitive receptors are selected as monitoring objects. Based on potential pollution during construction period and operation period, acoustic environment and environmental air are to be monitored. Monitoring indicators are determined based on pollution characteristic factors identified through engineering analysis. The monitoring analysis methods of corresponding items in Environmental Monitoring Technical Norms are adopted. Corresponding assessment standards defined in national standards and confirmed during environmental impact assessment are applied as evaluation criteria. According to the engineering and environmental characteristics, the environmental monitoring contents during construction period and operation period are determined.

It is recommended to introduce environmental supervision system for the project. The supervisor’s performance in undertaking environmental protection supervision responsibilities during construction period directly relates to implementation effectiveness of environmental protection measures at the stage. 6.1 Purpose of Environmental Supervision Implementation of environmental supervision on the proposed project aims to make environmental supervision and management responsibilities clear on construction site, and make objective clear, as well as implement supervision in the whole construction course of the project, so as to ensure that various environmental protection measures put forward in environmental protection design and environmental impact report can be successfully implemented, and that contract conditions regarding environmental protection as stated in construction contract can be put into practice. 6.2 Tasks of Environment Supervisor During construction of the project, tasks of environment supervisor include: 1) Management, i.e., management for collecting, classifying, handling, feeding back and storing information on supervision, environment and quality. 2) Coordination, i.e., coordination and organization between the owner and the contractor, the owner and design unit, various departments involved in the project construction. 3) Control of quality and progress. 6.3 Framework of Environmental Supervision 1) Establish and strengthen organizational system for environmental supervision Environmental supervision has dual natures. From the perspective of independence, professional mechanism must be set and full-time personnel with relatively high 55 professional quality must be allocated. It is recommended to incorporate the environmental supervision of the project into engineering supervision, in which full-time environmental protection personnel are required. As a result, the project quality can be comprehensively managed with dual requirements of project quality and environmental protection quality. In the project, environmental protection and supervision must be conducted under the supervision of regional and local environmental protection bureaus. 2) Formulate relevant environmental protection & management measures and implementation rules Based on national environmental protection policies, laws & regulations, and according to environmental monitoring & supervision plans formulated as per the environment assessment report of the project, relevant environmental protection systems of the project shall be established. 3) Establish a completed environmental supervision system ① Work record system, i.e., “supervisor diary”. Patrol inspection and environmental problem shall be described, causes for problem and responsible unit shall be analyzed, and preliminary handling comments shall be put forward. ② Reporting system, including “monthly report” of environmental supervision engineer, “quarterly report” and “half-year schedule assessment report” of engineer, and “monthly report on environment” of the project contractor. ③ Document notification system: Only working relationship should exist between environmental supervision engineer and the contractor, and affairs between the two parties should be communicated and confirmed by delivering documents. In case of emergency works, oral notification is firstly made, and a written document will be submitted for confirmation after the next day. ④ Regular environmental meeting system: It means that environmental protection meeting shall be held once a month to review and summarize the work of environmental protection for the last month. At the meeting, engineer, environmental supervision engineer and other relevant personnel shall gather together to discuss problems and rectification requirements, so as to unify thought and form implementation scheme. 6.4 Requirements on Environment Supervisor Since environmental supervision is a new topic, whether it can work or not greatly depends on the quality of environment supervisor.

Preservation and Management Regulations for Cultural Relics and Historic Sites If cultural relics and historic sites are found or suspected during construction period, the contractor shall immediately protect the site according to Law of the People's Republic of China on the Protection of Cultural Relics (December 29, 2007) and requirements as stated in material culture and resource policies of the World Bank, report to local Cultural Relics Bureau for handling, and carry out construction again after the handling by Cultural Relics Bureau. Report procedure for cultural relics is shown in Fig.5.1-1. When cultural relics and historic sites are found or suspected in the course of construction, the contractor shall: (1) Stop construction at position where cultural relics are found and strengthen protection for the site; (2) Report in a timely manner to police department and competent department of cultural relics for identification and handling; (3) Delimit protection range immediately once cultural relics are determined by experts; (4) Conduct rescue excavation for cultural relics in case of tight construction period or natural damage risk; (5) Let professional personnel to conduct rescue excavation for cultural relics by using special equipment, and do not excavate them randomly; (6) Conduct demonstration about whether alternative site shall be selected for continuous construction once major cultural relics are identified. 83 Discover cultural relics Stop construction and protect site Report to local administrative competent departments of cultural relic protection Administrative departments of cultural relics put forward handling comments The contractor prepares construction scheme for cultural relic section Disagree Comments of cultural relic departments Agree The contractor carries out construction according to the construction scheme Fig. 5.1-1 Handling Procedure for Cultural Relics Found During Construction Period 6. Environmental Protection Regulations on Noise Pollution Prevention During construction period, the major source of noise is mechanical noise generated by such construction equipment as excavators, cutting machines and transport vehicles, with sound level being more than 85dB(A). Whether shield is provided or not, areas within 30m, 80m and even 150m of construction site will be affected by construction noise at different levels. The following measures are taken to improve acoustic environment quality of the said main protection objects. (1) Environmental management on construction site shall be strengthened, and Noise Limits for Construction Site shall be strictly followed. In order to reduce impact of construction on surrounding residents, when route reconstruction is conducted near acoustic environmental sensitive objects listed in environment assessment and residential area, it is prohibited to carry out construction during 22:00 PM to 6:00 AM of the next day in noise sensitive points near to the route. Except for protection objects at noise sensitive point, for other routes to be reconstructed, construction time can be arranged according to project schedule and impact on traffic. 84 (2) In main traffic road, residential area and site of wastewater treatment and reclamation plant involved in layout of pipe and route, a notice to reassure the public can be posted, in which construction period shall be indicated. This can not only reassure the masses and get their understandings, but also supervise the contractor, which is conducive to completing construction on schedule. (3) In school and other sensitive points, high-noise equipment shall not operate during school hours. In residential area, high-noise equipment shall not operate during lunch time. In hospital and government office and other sensitive areas, operation time of high-noise equipment shall be shortened as much as possible. As for construction equipment and method, low-noise machine shall be adopted as far as possible, e.g., small machine. (4) The construction method of “concentrate efforts and carry out construction section by section” shall be adopted to shorten construction period and relieve impact of construction noise on acoustic environment in local sections. Except in busy sections, joint calking for pipe connection in other sections shall be carried out simultaneously in different batches. (5) Preventive measures for noise pollution shall be taken when route construction is carried out at sensitive points. Guardrail with a height of 1.5-2.0m can be used to shield construction noise at construction site. (6) In partial intensive residential areas and teaching areas, pipeline may be laid by man, so as to minimize impact of construction noise on residents and schools. (7) Isolating and protective measures shall be appropriately taken for construction site, so as to achieve good effect of noise reduction. (8) During road construction, noise is mainly generated by construction machines and transport vehicles. In order to ensure health of construction personnel, according to Sanitary Standard for Noise of Industrial Enterprise , it is recommended that the contractor shall rationally arrange schedule for workers and let them operate high-radiation strong-noise construction machines in turn to reduce their time of receiving high-noise. At the same time, the contractor shall pay attention to maintain machines and operate them correctly, so as to maintain the noise of road building machines at minimum sound level. It is recommended that operators and relevant personnel shall ware personnel protective articles, such as earplug and helmet. 7. Environmental Protection Regulations on Air Pollution Prevention During Construction During construction, main pollution factors for impact of proposed project on ambient air are construction waste gas and dust nuisance, for which, the waste gas mainly includes the exhausts from various construction machineries and transport 85 vehicles; during construction, the dust nuisance is mainly produced from subgrade excavation, site excavation and backfill, discarding of soil and stone, and loading, transportation of knocked-down construction garbage, transportation, loading and unloading of construction materials, and construction. And, few dust nuisance is also generated by site leveling, and the main pollutant is TSP. (1) Preventive Measures for Dust Nuisance Pollution From pavement excavation, pipe trench excavation, foundation excavation for structures on site to backfilling and covering, in order to prevent dust nuisance, construction site shall be embosomed (in the environment assessment, closed embosoming or semi-closed embosoming with color plate is recommended). If there is successive sound weather and wind during construction of pipe network, temporary storage area of excavated earth shall be watered or covered with green covering screen, to prevent dust nuisance. The contractor shall dispose spoiled soil timely as per plans, cover the compartment of vehicle transporting residual soil (keep the vehicle closed during transportation) during transportation and spray water on transportation route containing non-soil pavement. Besides, the contractor shall avoid excavating earth and handling materials under wind. The transport vehicles shall not be overloaded. Relevant measures shall be taken to prevent dropping of residual soil being transported during transportation. Before departure, soil attached on wheels of vehicles shall be swept out with broom to prevent falling off of spoiled soil to affect environmental cleanness. Besides, clean-keeping system shall be implemented for road under construction, to ensure spoiled soil can be timely cleaned up once being found. During construction, the major impact on ambient air is from dust. Dust is generated during excavation on dry ground surface and hole drilling, part of which will suspend in the air and other part will drift with wind and down to nearby ground and surface of buildings. In case of strong wind, dust will fly during pile-up of excavated soil, part of which will fly and fall off during handling & transportation of such excavated soil. The soil entrained by rushing rainwater is scattered on ground surface, and will generate dust nuisance due to movement of vehicles or wind after being dried. Backfilling of excavation earth will also generate a large amount of dust nuisance. Handling, transportation and stacking of construction materials will inevitably cause falling off and flying of dust. Hazard of dust pollution during construction shall not be neglected. If construction personnel and surrounding residents imbibe dust floating in the air, various respiratory diseases will be caused. What’s more, since dust contains lots of pathogenic bacteria infecting various diseases, health of construction personnel and surrounding residents will be seriously influenced. In addition, because flying dust will reduce visibility, traffic accident will be easily caused. Dust drifts down to buildings and trees and their leaves, affecting landscape. Therefore, the owner shall strengthen management and take 86 appropriate measures to strictly control dust generated during construction. In order to minimize impact of project construction on surrounding environment, the following preventive measures are recommended: 1) Special personnel shall be allocated to be responsible for constriction site, so as to realize scientific management and civilized construction. During construction of foundation, relevant measures shall be taken as much as possible to accelerate project schedule, and earth-rock shall be transported out to specified place to shorten hazardous period of stacking. 2) Floor of construction site must be hardened, and concrete floor may be adopted if conditions permit. 3) During excavation, hole drilling and demolition, water shall be sprayed to keep construction site wet in a certain degree. Specifically, loosen and dry surface soil on construction site shall be watered regularly to prevent dust; when soil is backfilled, dry surface soil shall be watered appropriately to prevent dust from flying. 4) To strengthen management for stacking yard of soil to be backfilled, measures for compacting, regular watering and covering of earth surface shall be prepared. Needless soil and construction materials shall be carried away in a timely manner, and should not be stacked for a long time. 5) Anti-spraying equipment shall be provided for truck transporting soil and transport vehicle of construction materials, and the load should not be too full, so as to ensure soil and materials will not be scattered during transportation. Running route and schedule shall be planned appropriately to avoid driving in such sensitive areas as busy area, intensive traffic area and residential area. In section with high environmental requirement, transportation shall be conducted at night based on actual conditions, so as to reduce impact of dust on environment. 6) Top of transport vehicle shall be covered, and handling site shall be washed cleanly before handling to prevent soil carried by wheel and chassis from falling on road surface. 7) Soil scattered on pavement during transportation shall be swept timely to reduce dust during running of transport vehicles. 8) Sand and cement, which are stacked outdoor and will easily generate dust nuisance, shall be covered with canvas and plastic cloth to prevent dust from spreading. 9) During construction, it is prohibited to use discarded construction materials as fuel. 10) Fence on demolition construction site shall be complete. 87 11) After completion of construction, road and vegetation on the land occupied by construction shall be restored timely. 12) Demolition and road construction sites shall be embosomed with color steel plate. 13) Transportation shall be rationally arranged. Bulky members and massive materials as well as spoiled soil required during construction shall not be transported in rush hours, so as to relieve traffic pressure and minimize automotive emission. (2) Preventive Measures for Tail Gas Pollution Caused by Construction Machines and Transport Vehicles Construction machines & equipment and transport vehicles conforming to national health and protection standards shall be adopted so that the gas emissions can meet relevant national standards. Overload limit, speed limit, exhaust purifier installation, and other measures can be taken to reduce impact of the exhaust from transport vehicles and construction machines on the surrounding residential area. 8. Environmental Protection Regulations on Water Environment Impact (1) Stacking of construction materials including asphalt, cement, oil fuel and chemicals shall be managed properly, and coverings shall be added during stacking. Such construction materials shall not stacked besides rivers, when necessary, fence shall be provided to prevent such materials form being rushed into rivers along rainwater runoff to cause pollution in case of rainy season or rainstorm. (2) During construction of pipes along or crossing rivers, it is prohibited to dump waste from pipe installation into the rivers nearby. Such waste shall be transported to specified filling position of subgrade or to specified location for disposal. (3) Intercepting ditch shall be provided around machine storage yard within maintenance area, to prevent mechanical grease dirt form being rushed into surrounding environment along rainwater to cause pollution. Wastewater collected in the intercepting ditch shall be naturally evaporated after oil and precipitation treatment. Household waste generated shall be managed properly, and collected regularly and transported to specified location for disposal. Machines in maintenance area shall be maintained to prevent pollution by mechanical grease dirt. (4) Heavy grease leakage from construction machines shall be prevented. It is prohibited to discharge oily water produced during running of machines into nearby water bodies. It is also prohibited to discharge oily water produced during maintenance of construction machines into water bodies. (5) In addition, the proposed project is municipal construction project, folk houses, unused plant and warehouse can be rented and used as construction camp. During 88 construction, household wastewater generated by construction personnel can be discharged into municipal wastewater pipe network, and finally delivered to wastewater treatment plant to be treated until standard is met, and then discharged, so as to reduce pollution on environment. (6) Without prior written consent of supervision engineer, the contractor shall not, for any purpose, interfere natural flowing of river course, water channel or existing irrigation system or drainage system, so as to avoid occurrence of flushing and deposition. 9. Environmental Protection Regulation on Solid Waste Disposal The solid wastes produced during construction period of the project mainly include construction waste, household waste, and waste from the environmental management of river bank and the ditch clearance and transportation, and sludge from ditch clearance. Most construction wastes generated during construction period are inorganic wastes which mainly compose of offcut in construction such as discarded mound, tiles, concrete blocks, etc. There are also a small number of organic wastes which mainly include various packing materials such as discarded old plastics, plastic foams, discarded paint and coatings, etc. Surrounding landscape and environmental quality will be affected if these wastes are not disposed properly as they are non-perishable and insoluble. In order to avoid these problems, it is suggested in the EIA that construction wastes generated during construction period shall be transported at any time to the Yinjiagou domestic solid waste landfill for unified disposal or comprehensive utilization. Discarded earth and stone work excavated in construction shall be returned to nature by means of disposal on the spot and be properly filled and compacted. The household waste mainly composes of organic waste including leftovers and feces. If being piled in construction site without timely and effective disposal, these solid wastes will rot, stink and breed flies, and even trigger infectious diseases when it becomes worse, affecting the health of construction personnel. The household waste during construction period of the proposed project is disposed in a unified manner by stacking in specified places and transporting to Yinjiagou landfill in a timely manner. The waste from the river bank environmental improvement and gully clearance includes mainly construction waste and household waste, both being ordinary solid waste and can be transported to Yinjiagou Landfill after being collected. Canal clean-up will be done for Chaoyangdianqu canal as part of gully improvement component. Chaoyangdianqu canal used to be a water channel with function of power generation, now it is mainly for agricultural irrigation. It is surrounded by villages and farmer households, without industrial enterprises. The wastes discharged into the canal are mainly domestic wastewater and household waste. The sludge in the canal is of 89 general composition, which will be delivered to Xining Landfill. During clearance and transportation of solid waste, management shall be strengthened to avoid secondary pollution in the process. (1) The Owner and relevant departments should jointly formulate proper spoil disposal and transportation plan. Transportation of waste slag at peak traffic times shall be avoided. The transportation of soil residue in bustling downtown sections is prohibited and such transportation should be arranged at night as far as possible. (2) The contractor of the project shall timely carry away waste slag according to spoil disposal plan. Overload shall not occur. Loader carrying slag shall be slow during driving to reduce spill and leak and keep the city clean. (3) The Owner shall go hand in hand with the relevant departments undertaking transportation to properly educate drivers about professional ethics, and urge proper waste transport according to the specified route, places and time. Non-scheduled inspection shall also be made. 10. Environmental Protection Regulation on Ecological Environmental Protection (1) Protection Measures for Vegetation ① The current farmland and trees shall be properly protected. It is recommended that construction personnel should receive relevant training before temporary land is used. Civilized operation without damage except the works shall be emphasized. Management shall be strengthened. Strict protection of the trees and vegetation within the temporary land is required to reduce damage to the ecological environment along the project as far as possible. ② The construction of the project, landscape engineering, slope protection, and drainage ditch shall be performed at the same time. It is best to simultaneously carry out utilization, leveling, greening and reclamation. But in view of feasibility, leveling and greening shall remain to be the focus after completion of the works. ③ The land temporarily occupied shall be leveled and reclaimed or greened and renovated in time after completion of the works. ④ The green vegetation outside the land in use shall be protected to the greatest extent. If the current green vegetation is damaged due to construction of temporary works, reclamation shall be undertaken when temporary works are demolished. ⑤ The area of vegetation damaged by the works during construction period shall be strictly controlled. No human destruction shall take place other than inevitable land occupation and tree cutting for the works. 90 ⑥ The education about protection of natural resources and wild animals shall be strengthened among construction personnel. Cutting trees at random is prohibited in employment contract. (2) Protection Measures for Cultivated Land ① Since the proposed project is located in Xining Municipality and its surrounding area, the construction of pipe network and road is bound to have certain impacts on agricultural development along the project. The unnecessary land shall be occupied as little as possible or not occupied in construction. Operations shall be performed within reach of land used for the project according to greening design requirements. ② The cultivated land shall be occupied as little as possible. The process of taking and removing soil shall be combined with the agricultural development and planning design and the farmland capital construction to provide convenience for developing local economy and solving local practical problems. ③ The requirements of relevant policies shall be carefully implemented for greening of the project. The width of greenbelt shall be strictly controlled if the project is surrounded by cultivated land. (3) Greening Measures ① Greening measures for main road: Certain amount of vegetation is damaged by slope surface of the proposed highway, temporary land occupation, etc. The vegetation damaged thereby is mainly restored by revegetation. When greening tree and grass species are selected, the basic principle of “matching species with the site” shall be followed to determine the species of trees and grass. Priority shall be given to native trees and grass. Secondary are the introduced trees (grass) that have become accustomed to the local natural environment after being planted for many years. According to the conditions of areas passed through by the proposed highway, the selected trees shall be hardy variety with high survival rate and be characterized by cold resistance, drought resistance, tolerance to barren soil, developed root system, and strong ability in stabilize soil. The grass shall be local grass variety easy to survive. The leanness-resistant hardy grass prone to humus shall be selected. ② Plant measures for areas directly impacted: The areas directly impacted include several types, i.e. cultivated land, barren slope (wasteland), and grassland. The principle for greening of areas directly impacted is to restore the original land use types after completion of the main works. Therefore, land remediation and reclamation to farmland are carried out for cultivated land after completion of the works. Land remediation is carried out for barren slope and grassland after completion of the works to create mixed forest of arbor and shrub or plant grass of quality. ③ Greening measures for other occupied land: They are mainly to restore the 91 farmland and vegetation damaged by borrow pit. 11. Environmental Protection Regulation on Water and Soil Conservation The excavation method of earth and stone work shall be reasonably arranged in construction. Earth and stone work shall not be discarded nearby at random. No waste disposal area is provided for the project. All the earth and stone work shall be reused. The earth and stone work involved in the project must borrowed and stacked at the borrow pit and temporary waste yard specified in the scheme. (1) Borrow Pit The borrow pit site was not specified during feasibility study period of the proposed project. Borrowing earth will unavoidably change surface condition, disturb soil structure, and damage vegetation. With respect to the negative impacts caused by the project construction, the following preventive measures must be properly taken to try best to minimize water and soil loss. ① Before excavation of borrow pit of the project, the surface humus soil is stripped and stacked in a centralized manner in proper location near to the site and is used for follow-up greening. ② Rainfall concentrated period shall be avoided as far as possible to borrow earth. In the process of excavation, in order to reduce rainfall runoff intrusion that increases weight of loose soil and leads to gravitational erosion, ditches shall be arranged at two sides of borrow pit to allow the surface runoff to discharge in time. ③ Earth covering shall be carried out in the pit after completion of borrowing and then revegetation is performed. The type of revegetation depends on the original land vegetation. Meanwhile, according to the rock and soil types of back wall after excavation, slope cutting and stepping is carried out for it. Water conservation measures are provided accordingly. With respect to rock slope, slope shall be cut at the grade below 1:1 and wire mesh shall be hung on slope surface to plant grass. With respect to soil slope, slope shall be cut at the grade below 1:1.5 and grass and shrubs shall be planted on slope surface. Intercepting ditch shall be set at slope top of back wall of borrow pit.

This portion of spoil is stacked at temporary waste yard. Before stacking earth, stacking scope is strictly divided, simple walls to retain water and wind shall be provided, and drainage ditches shall be dug. The temporary waste bank shall be timely used over implementation of greening to avoid prolonged exposure. After completion of greening, leveling shall be performed, and spontaneous recovery or 92 plant protection shall be carried out depending on local conditions. Various prevention and control measures adjusted to local conditions shall be taken for the water and soil loss within scope of responsibilities of this project to effectively control newly increased water and soil loss amount and gain effective management of original natural water and soil loss. After completion of construction, clearance and remediation shall be carried out for land temporarily occupied. Temporary buildings shall be demolished, ground shall be cleaned, the soil compacted after being rolled shall be loosened again, low-lying land shall be filled up by earth covering, and greening shall be performed in time to minimize the level of water and soil loss.

The construction of drainage ditches and construction roads are simultaneous. 93 ③ Based on subgrade protection engineering of construction road and drainage works, protection is carried out in sections by combining topographic and geological conditions and construction characteristics. According to the different situations of each road section, protection measures for plant are arranged. Based on the principle of “matching species with the site”, consideration is given to the requirements of protection and greening and beautification, local conditions and characteristics of vegetation are combined, and thus local excellent native tree and grass species are selected for roadside greening according to comprehensive analysis of survival ratio and adaptability, so as to realize the purpose of preventing water and soil loss and improving greening environment. ④ If construction roads are unavailable in borrow pit, temporary waste bank and waste disposal area, or road width does not meet the requirements, supplementary design shall be performed for this scheme and road width shall be designed as 4.5m.In construction, construction vehicles shall be strictly required to drive on designed road to avoid random rolling that damages original surface and vegetation and leads to new water and soil loss. (5) Standard Construction a During construction period, the damage by the works to aboveground vegetation shall be reduced as far as possible. The selection of construction season shall be adjusted to local conditions and the seasons when plants grow fast shall be avoided. As for construction in forest land, manual work shall be adopted as far as possible to minimize area of operation. b Efficiency of construction shall be improved to shorten construction time and reduce exposure duration of bare land. c The operation specifications for excavation in layers, stacking in layers, backfilling according to layers (undersoil is at bottom and topsoil is at top) of soil during construction period shall be strictly implemented. The original survival conditions of plants shall be maintained as far as possible to facilitate the recovery of vegetation. Proper accumulation layer shall be provided during backfilling to prevent surface depression and water and soil loss caused by precipitation. 12.

After excavated, aboveground vegetation disappears and soil erosion modulus in local range increases due to certain gradient (height difference). After being excavated, quarry area and borrow pit are easy to cause water and soil loss if without timely restoration and greening. 2) Impact on landscape Borrow pit will damage vegetation and change original terrain, landform and natural landscape. 3) Mechanical noise produced by earth borrowing has impact on acoustic environment. 4) Dust nuisance caused by borrow pit has impact on ambient air. 5) If the excavated topsoil of borrow pit is not piled well, the water and soil loss is easy to happen. (3) Environmental Practice Regulation for Borrow Pit 99 According to site selection requirements for borrow pit and its impact on environment, the setting of borrow pit shall meet the following requirements: 1) Exploit nearby and take full use of the spoil from the project, use existing legal borrow pit in local as much as possible, and reduce the impact on ecological environment caused by exploitation of rock material and earth borrowing. 2) During soil borrowing, the side ditch collecting rain shall be constructed to avoid the occurrence of water and soil loss, debris flow and the like in rainy season. 3) During construction, deep excavation is avoided, the excavated earth and rocks and filled earth and rocks shall keep balance, and if borrowing of earth and rocks is required, coordination shall be performed for the soil spoiled from other construction items within the project area to avoid separate establishment of a borrow pit, which can eliminate the impact of borrow pit on environment fundamentally. 4) To reduce the quantity of borrow pit, the soil borrowing shall be centrally conducted for the project. 5) To reduce dust pollution caused by earth excavation, during soil borrowing, water shall be sprayed for dust suppression. 6) To prevent water and soil loss and the lost sediment directly discharging into surface water following the runoff in the drainage ditch to affect the water quality, intercepting drain and drainage ditch shall be constructed in borrow pit. 7) During excavation, the topsoil shall be kept and then applied to the land rehabilitation. In addition, the topsoil shall be temporarily piled in the relative flat area at the site, with temporary fence built with bagged soil. Temporary drainage ditch and desilting facility covered by dust screen shall be provided around. After the construction is completed, the topsoil shall be applied to the ecological restoration of borrow pit. 8) Through following the principle of simple and easy to be maintained, adopting greening method of integration of trees, shrub and grass which will form plant communities landscape, restore the natural ecology of quarry area and borrow pit and reduce the water and soil loss. 9) Strictly control construction time. If there is sensitive target (such as settlements and the like) within the scope of noise impact, then it is prohibited to conduct quarrying and soil borrowing during 12:00-14:00 and 22:00-6:00. 15.

(2) Landscape Design Bridge location selection needs to be done by taking into account landscape design of bridge to make it coordinate with local cultural landscape. (3) Solid Waste Yard The proposed bridge involves relatively large volume of earth and rock, and all pier foundations may produce some solid waste, so one proper site must be selected to dispose the spoiled earth and rocks. Otherwise, water and soil loss will occur or the cultivated land will be polluted. Therefore, the solid waste yard shall be designed in design stage and ask for the advice of local environmental protection department and government sector for the design. 2. Environmental Protection Measures at Construction Stage (1) Environmental Protection Measures during Construction of Main Bridge 1) The Owner shall appoint special personnel to handle environmental protection problems occur during construction and operation periods of main bridge, handle environmental problems between the Contractor and environmental protection object (approach bridge), and supervise implementation of environmental protection measures during construction period.

Besides, the Contractor shall also strengthen equipment management and maintenance, and prevent leakage of petroleum material and building materials being transported, so as to reduce possibility of pollution on water area. 102 3) The Owner shall prepare & print and publicize data on environmental protection to distribute to each Contractor, and give education on environmental protection to all construction personnel to improve their environmental protection awareness. 4) During construction of main bridge, it is strictly prohibited to discharge muck of bored pile, construction waste, domestic wastewater produced by workers on water platform and solid wastes (such as household wastes) into Beichuan River. Toilet and dustbin shall be set on the platform and cleaned by specially-assigned person. It is not allowed to discharge or throw anything into the River, so as to reduce pollution on water quality. 5) From the prospective of environmental protection, the following principles are proposed to treat such solid wastes: ① The solid wastes produced during construction of main bridge pier must not be thrown into Beichuan River. This shall be stipulated with clear clauses in bidding documents. Specific penalty system shall be defined for all contractors who are found that they discharged solid wastes into river course. In addition, the design unit shall set solid waste yard properly within the land requisitioned for road, stacking method and proposal for treatment of waste surface based on quantity of earthworks, and confirm jointly together administrative competent departments of environmental protection and local government. ② Before stacking the solid wastes, a dam shall be built around such wastes to prevent them invading ambient environment in the form of mudflow and polluting environment. The Contractor shall solidify and stack the solid wastes that may flow, e.g. mixing with appropriate cement and leveling the waste surface after stacking. ③ For solid waste yard or slope of such wastes, the Contractor shall cover the yard surface with straw curtain before local rainy season, so as to reduce water and soil loss caused by surface exposure of the stacked wastes. ④ When works about pier is completed and the solid wastes need not to be stacked, top surface or slope surface of the stacked solid wastes shall be renovated, and greened after earth backing, such as planting trees or grasses, so as to increase vegetation coverage of the surface of the stacked solid wastes and reduce water and soil loss. 6) When filling subgrade, water shall be sprayed as required by material compaction. The Contractor must also spray water frequently after the material compaction, ensuring the material will not fly in the air. (3) Measures for Environmental Protection during Construction of Approach Bridge and Connection 103 1) During construction, advanced equipment shall be adopted as much as possible to reduce interference of construction noise on normal life and rest of nearby residents. During construction, equipment with big mechanical noise shall stop operating during 22:00 PM to 06:00 AM of the next day, so as to ensure normal rest of residents at night. It is worth mentioning that construction of such a large project in suburban area must produce much interference on normal life and convenient travel of local residents. Except that necessary preventive measures are taken to relieve interference, the Contractor shall post notice in entrances & exits and residential area. The Contractor shall ask for pedestrians' or residents' understanding and support, give psychological comfort to people affected by construction and give their support in action, so as to reduce incoordination caused by construction. This is conducive to promoting progress of works. 2) Solid wastes drilled (excavated) during construction of bored pile of approach bridge pier must not be stacked anywhere and shall be disposed as required by the report. New water and soil loss must be prevented. 3) Requirements on environmental protection measures for construction personnel's camp shall be subject to provisions of the report. 4) Water must be sprayed based on weather conditions on construction site and access road as well as when subgrade is filled in connection works. For construction materials scattered on urban roads, the construction contractor of each bid section shall appoint special personnel to sweep timely, so as to reduce pollution of dust nuisance on ambient air quality. 104 Attachment 4: Management Regulation on Protection Measures for Intercepting Main Sewer Construction 1.

Labor Protection The principle of “Safety First, Precaution Crucial” shall be carefully implemented to ensure that the project construction and use are consistent with national safety requirements, and ensure that workers are not injured during production and their health is not affected. 2. Analysis of Main Hazard Factors There are mainly two types of hazard factors of the Project. The first is hazards and adverse effects caused by natural factors mainly including earthquake, unfavorable geology, summer-heat, lightning stroke, storms, etc; the second is hazards formed during production including hazardous gas and dust, fire and explosion, mechanical injury, noises and vibration, electric shock accident, high-attitude falling, collision, etc. (1) Analysis of natural hazard factors 1) Earthquake Earthquake is a natural phenomenon which can cause great destruction especially on structures and buildings. As the impact scope is large, earthquake can be a great threat to safety of equipment and personnel. 2) Storm and flood Storms and flood can threat safety of wastewater treatment plant. Though their impact scope is large, they rarely happen. 3) Lightning stroke Lightning stroke can damage buildings, structures and equipment and might cause fires and explosion. But it rarely happens and the action time is short. 4) Unfavorable geology Unfavorable geology can cause great damage to buildings and structures and even threaten personnel security. But damage to buildings and structures by the unfavorable geology in the same region happens only once with short action time. 5) Wind direction It is very unfavorable for personnel downwind the hazard sources as the wind direction has obvious effect on transmission of hazard substances. 111 6) Temperature Human body requires appropriate scope of ambient temperature. If such scope is exceeded for certain extent, the human body will feel uncomfortable. If temperature is too high, human body might suffer heat-stroke; if temperature is too low, human body might be injured by extreme cold. Effect of temperature on human body is large with long action time. But the harmful consequence is slight. In a word, natural hazards are basically inevitable as they are generated naturally. However, relevant protective measures can be taken to relieve injuries or damage to personnel and equipment. (2) Analysis of production hazard factors 1) High-temperature radiation When intensity of high-temperature in work place is larger than 4.2Jm2·min, human body will be overheated leading to series of physiological function changes such as unbalanced thermoregulation and water and salt metabolic disturbance. The digestive and nervous system are also affected. These changes are showed as inattention, poor coordination and precision of actions which can easily induce accidents. 2) Vibration and noises Vibration can cause vibration disease which is mainly showed as dizzy, asthenia, sleep-disorder, palpitation, cold sweat, etc. Noises can not only damage hearing organ but also cause unfavorable impact on nervous system and cardiovascular system. After long-time exposure to noises, people can get headache and dizzy, feel fatigued easily and become forgetful. Incidence of coronary disease is also increased. 3) Fire alarm and explosion Fire is a kind of fierce combustion. Out-of-control combustion can cause fire accident which will lead to great personnel and property loss. Like fire hazard, explosion can also cause great casualties and property loss. 4) Other safety accidents Pressure vessel accident can cause damage to equipment and threaten personnel safety.
