General Hezhou Municipality is located in the northeastern part of Guangxi Zhuang Autonomous Region (GZAR) in Southwest China. A prefecture-level city established in Year 2002 with Hezhou Prefecture and Wuzhou Prefecture as its predecessors, Hezhou Municipality administers two districts of Babu District and Pinggui Administration District and three counties of Zhongshan County, Fuchuan Yao Autonomous County and Zhaoping County, with a total population of 2.35 million. Hezhou Municipality is located at east longitude 111°25′ ～ 112 ° 03 ′ and north latitude 23°39′～25°09′ and covers a total area of 11,855km2. Hezhou Municipality is located at the border area of Hunan Province, Guangdong Province and GZAR, known as the “Three-Province Thoroughfare� and “Backyard of Guangdong, Hong Kong and Macao�. Along with the construction of four expressways of Gui-Wu Expressway, Guang-He Expressway (2009), Yong-He Expressway (2010), and Nan-He Expressway and three railways of Luo-Zhan Railway (2009), Gui-Guang High-Speed Railway and Liu-Shao Railway as well as the development of airport and harbor, Hezhou will set up an integrated transportation network with all-directional reach and embrace unprecedented development opportunities. Hezhou Municipality does not only have advantages of geographic location, but also has rich ecological resources, in particular forest resources far much higher than the national average. Hezhou has a forest coverage rate of 72.88%, higher than the national average by a factor of 3.6 and ranks the second in the region. In addition, Hezhou Municipality has outstanding air quality and hot springs, waterfalls and beautiful scenery are distributed all over the city. Hezhou’s rich ecological resources have now become its most significant advantage and core competitiveness. He River is the main river in Hezhou Municipality and runs across the city from northwest to southeast before it joins Xijiang River System in Fengkai, Guangdong. Finalization of the city’s development strategy of "further expansion to the southern and western parts, further extension to the eastern part and focused optimization of the northern part� and the development orientation of “an emerging industrial and tourism city along Gui-Guang Economic Belt and portal and hub city in Northeast Guangxi� has paved the way for He River to become an important river in the urban centre in Hezhou serving the important functions of industrial and agricultural water supply, urban flood discharge and providing services for the cultural activities of local residents. Within the context of high-speed industrialization and urbanization and intensified global climate change over the recent years, Hezhou is in the face of increasingly prominent issues of frequent water disasters, aquatic ecological imbalance and water pollution and so on. All such issues have impeded the development of local economy and society. The main problems in flood control and water environment that Hezhou faces in the current stage include: Firstly, the flood control and drainage infrastructure in the urban area of Hezhou is very weak in contrast to the frequent flood events. He River runs through the urban -1- area of Hezhou Municipality, the major part of which is located in He Riverside belt along He River with no built dike or revetment in most parts. Without a sound flood control system, He River Watershed is very poor in terms of flood control. The increasingly frequent flood events have resulted in increasing serious economic losses. In the latest flood event in mid-November 2015, Hezhou experienced the heaviest winter rainfall ever recorded and 33 townships/towns/communities in the five counties/districts with a total population of 83,450 (including 4376 people for emergency displacement) and a total farmland area of more than 3100 ha were affected, ending up with a direct economic losses of over CNY 70 million. Secondly, municipal infrastructure construction is slow and the living environment needs further improvement. In Hezhou, which was established as a municipality quite recently, the existing municipal infrastructures constructed at lower standards and the road network poorly planned in both layout and structure cannot meet the needs of the growing size of the city. Most of the drainage networks are combined system of wastewater and stormwater constructed in 1990s against lower design standard. In the developed areas, wastewater and rainwater are directly discharged into adjacent rivers or He River via surface flow or ditch without any treatment, resulting in deteriorated water quality in city rivers and He River. The key water quality indicators, such as ammonia nitrogen, total nitrogen and fecal coliform, have exceeded relevant standards, implying the presence of pollution from domestic wastewater. Thirdly, some urban inland canals are slow in terms of water flow and deteriorated in terms of water quality because sediments and debris carried by the inner rivers of Huangansi and Shizigang flowing through the built urban area deposit on He River bed due to the absence of effective sewage interception. This situation is worsened by direct discharge of domestic wastewater of riverside residents and organizations. Consequently, He Rivers are very poor in terms of water quality and suffer from severe odors and black water. Deteriorated water environment and poor municipal infrastructures have become a bottleneck for external communication and economic integration, a serious restriction to the social and economic sustainability of Hezhou Municipality and a serious threat to the water security of Pearl River-Xijiang River Watershed. In order to promote the flood control capacity of He River and the drainage capacity and integrated utilization of water resources in the project area and improve the ecological environment and municipal infrastructure of Hezhou Municipality to support integrated development of the city, Hezhou Municipal Government decided to apply for a loan from the World Bank (Hereinafter referred to as “WB�) for the project. WB Loan Guangxi Hezhou Urban Water Infrastructure and Environment Improvement Project has been included in the national list of candidate projects utilizing WB loans. According to WB’s environmental policies, the project is categorized as a “Category A� project requiring a complete environmental impact assessment report, an environmental & social management plan and an executive summary. Hezhou Municipal Project Management Office of WB Loan (hereinafter referred to as the "PMO") entrusted Guangxi Zhengze Environmental Protection Technology Co., Ltd.

The results are shown in Table 1-1 below. Table 1-1 Correlation Analysis of the Project and the WB Safeguard Policies Safeguard S/N Triggered ? Explanation Policies The project is designed to assist Hezhou Municipality to address its existing challenges on environmental protection and flood control. The proposed investments include river rehabilitation and dredging, improvement of drainage system (pumping stations), construction of sewage interceptor, WWTP and associated pipelines and roads, and strengthening of water and ecological environment monitoring capacity. Based on the characteristics and scope of the Project, it is anticipated that the Project will involve the following environmental impacts: (1) The construction activities in the downtown area of Hezhou Municipality will generate certain environmental Environmental and social impacts, especially to the nearby residents 1 Assessment Yes and historical and heritage buildings on Xiyue Street. OP/BP 4.01 (2) Dredging of He River and its tributaries will generate environmental and social impacts. In the EIA process, the sludge nature and dredging quantity have been assessed and methods for dredging, sludge transportation, treatment and disposal are designed to minimize the impacts on local environment and residents. (3) The construction works under the Project (river rehabilitation, pumping station and wastewater treatment plant) will involve land acquisition and resettlement and thus significant social impacts. (4) The Project and the other development activities already -5- Table 1-1 Correlation Analysis of the Project and the WB Safeguard Policies Safeguard S/N Triggered ? Explanation Policies implemented, to be implemented and reasonably foreseeable on the urban section of He River will have accumulative impacts on flood control and water environment, which, according to analysis, are primarily positive impacts. Therefore, the Project triggers World Bank OP4.01 and is identified as Category A Project. The policy is triggered because the construction and operation of proposed WB investments will have impacts on natural habitats including aquatic and terrestrial ecosystem along He River and its tributaries. As per the requirements of OP4.04, survey on aquatic and terrestrial ecosystem were conducted in the project-affected area and no critical/sensitive natural habitat has been identified. The Natural project-related ecological impacts will be generally positive, 2 Habitats Yes and the anticipated adverse impacts are short-term, OP/BP 4.04 temporary and site-specific. The project has been developed in an environmentally sustainable way considering the protection of local species and biodiversity, and the specific mitigation measures were incorporated into the ESMP and ECOPs to ensure the potential adverse impacts were sufficiently addressed during construction and operation. The project will not finance activities that involve significant Forests conversion or degradation of critical forest or related critical 3 No OP/BP 4.36 habitat defined under the policy. This policy will not be triggered. Pest The proposed project will neither procure pesticides nor 4 Management No result in increased use of pesticides. This policy will not be OP 4.09 triggered. The EA process confirms that He River rehabilitation subprojects of He River main watercourse rehabilitation (Guangming Bridge - Lingfeng Bridge section), Huang’ansi Physical Flood Discharge Pump station and Discharge Canal Cultural Rehabilitation will have indirect impacts on some ancient 5 Yes Resources buildings on the nearby historical and cultural street of Xiyue OP/BP 4.11 Street in the construction stage. In particular, a 120m-long downstream section of Huang’ansi Channel is part of this provincial-level protected historic quarter. A PCR management plan has been developed as part of the ESMP -6- Table 1-1 Correlation Analysis of the Project and the WB Safeguard Policies Safeguard S/N Triggered ? Explanation Policies and mitigation measures have been developed to avoid, minimize and compensate the project-related impacts. In addition, the RAP survey also found that the subproject of central green corridor will affect 53 new tombs of rural family and might generate impacts on local sacrificial customs. All the compensation and relocation measures for those tombs have been formally planned and developed in the RAP based on detailed survey and extensive consultation. The Project is located in Hezhou Municipality of GZAR. Indigenous According to the investigation, there are no ethnic minorities 6 Peoples No in the project areas. Therefore, the project will not affect the OP/BP 4.10 ethnic minorities. Details will be further investigated during the project preparation. Project components, including watercourse widening of He River and its tributaries for flood discharge, river-lake Involuntary connection, Jiangnan WWTP, will involve extensive 7 Resettlement Yes occupation of land and also private house demolition. OP/BP 4.12 Therefore, in the project design, the impact of land acquisition has been minimized. The Project triggers OP4.12 and a Resettlement Plan has thus been prepared. It has been found during environmental screening that there are two dams upstream of the proposed WB Loan Project. However, there are three small hydroelectric stations involved in the Project for rehabilitation. This policy is therefore triggered considering their direct impacts on the Safety of safety of proposed interventions. The Borrower has 8 Dams OP/BP Yes arranged one independent dam specialist to: 1) Inspect and 4.37 evaluate the safety status of existing dams identified as relevant; 2) Review and evaluate the owner’s operation and maintenance procedures; and 3) Provide a written report of findings and recommendations for any remedial work or safety-related measures. Projects on International This Project involves no international waterways. The policy 9 No Waterways is not applicable and no action is required. OP/BP 7.50 Projects in Disputed All the project areas are in Guangxi and no disputed areas 10 No Areas OP/BP are involved. 7.60 -7- 1.2 Objectives of EIA The main objectives of the EIA is to identify the current status of natural and social environment and environmental quality; evaluate the positive environmental impact of the project implementation; identify, screen and predict the possible negative impacts; propose effective mitigation measures and provide environmental & social management plan for the unavoidable negative environmental impacts so as to provide a rationale for the WB’s independent assessment of the project as well as references and basis for project decision making, environmental management and engineering design optimization. 1.3 Principles of EIA The EIA shall be organized and implemented in accordance with the principle of sustainable development and in a scientific, fair and practical way to support environmental decision-making and management. Principles to be followed include: (1) Complying with the national industrial polices, environmental policies and regulations; (2) Complying with the watershed and regional functional zoning plan, ecological protection plan and urban master plan and adopting an appropriate layout; (3) Complying with laws and regulations on ecological protection such as biodiversity; (4) Complying with policies of integrated resource utilization; (5) Complying with land use policies; and (6) Complying with pollutant discharge standards and regional environmental quality requirements. 1.4 Environmental functional zoning and evaluation criteria 1.4.1 Environmental functional zoning and environmental standards in force (1) Atmospheric functional zoning According to the Principles and Technical Method for Environmental Air Quality Functional Zoning (HJ14-1996), the project is located in a functional area subject to Class II standard specified in the Ambient Air Quality Standards (GB3095-1996）.

Engineering analysis 2.1 Project overview 2.1.1 Project background Within the context of high-speed industrialization and urbanization and intensified global climate change, Hezhou is in the face of increasingly prominent issues of frequent water disasters, aquatic ecological imbalance and water pollution and so on. All such issues have impeded the development of local economy and society. The main problems in flood control and water environment that Hezhou faces in the current stage include: Firstly, the flood control and drainage infrastructure are very weak in contrast to the frequent flood events. Secondly, the issue of environmental pollution has not been resolved. Thirdly, some urban inland canals suffer from deteriorating water quality due to limited water flow. And fourthly, the living environment is yet to be improved on account of the slow progress of municipal infrastructure development. These prominent water environment issues and the poor municipal infrastructures have become a “bottleneck� for economic integration, an obstacle to sustainable economic and social development, and a threat to water safety in the Pearl River and Xijiang River Watershed. In order to improve the flood control capacity of He River, the drainage and integrated water resource utilization in the project area and the ecological environmental and municipal infrastructure in Hezhou, Hezhou Municipal Government (HMG) decided to work with the World Bank and utilize a WB loan to implement Hezhou Urban Water Infrastructure and Environment Improvement Project. 2.1.2 Project objectives To be implemented following the guidelines of development, livelihood and innovation and the principles of stabilized growth, deeper reform, strengthened restructuring, improved livelihood, controlled risks and integrated balancing and taking into consideration the relevant special plans and the practical situation and economic conditions, the Project intends to develop a system that covers flood risk management, urban drainage improvement, water environment improvement, ecological landscape promotion, and technical assistance management, etc. In addition, the Project will adopt the standards of “green water service, eco-friendly water service and storm and flood safety� to implement water environment rehabilitation and urban infrastructure development, safeguard regional drainage and flood safety, and improve regional water environment, and develop high standard and modern urban infrastructure and public service to support the sustainable development of Hezhou and demonstrate the integration of reform and innovation. 2.1.3 Project description Hezhou is located in the northeastern part of GZAR. He River is a part of the Xijiang River System in the Pearl River Watershed and a major tributary of Xijiang River. It runs from northwest to southeast across the urban area and joins Xijiang River at - 17 - Huikai in Guangdong Province. Along with the all-direction expansion of Hezhou Municipality that identifies itself as an industrial and tourism city on the Guizhou-to-Guangdong Economic Belt and a portal and hub for Guangxi to the northeast direction, He River has become an important watercourse in the urban area with important functions to serve the city’s needs for industrial and a gricultural water, drainage and residents’ cultural activities.

(2) Construction schedule The Project will be implemented in three stages: the preparation stage, the main works construction stage and the completion stage. The main tasks in the preparation stage are construction of access roads, living and production facilities inside and outside the project site; the main works construction mainly includes earthwork excavation, backfill, and construction of slope, dike, pumping stations and water gates; in the completion stage, the main tasks are site cleanup and documentation. Based on the actual conditions, the Project is scheduled to be constructed over a period of 7 years, commencing in early January 2018 and ending with the final acceptance test at the end of December 2024. 2.2 Current conditions 2.2.1 Current conditions for urban flood control Hezhou is located in the Babu Basin, spreading from east to west like a belt along He River. The elevation along He River is relatively low, with the minimum elevation of the built area ranging from 102.08 m to 103.08 m. As a result, buildings and streets in these areas suffer from flood almost every year. According to the historic records, the City was hit by major floods in the years of 1813, 1908, 1914, 1915, 1954, 1956, 1978 and 1994. Since the city was established, Hezhou Municipality has experienced major floods in the years of 2002, 2005, 2008 and 2020, with both the urban and rural areas - 31 - flooded by river water overflowed from the dike, causing significant waterlogging and flooding disasters. The flood in 1994, in particular, caused huge loss in the urban area. Hezhou is an emerging tourism city with its infrastructures being developed in all aspects. Its first effort in development of special plans for flood control can be traced back to Year 1995. However, up till now, the city still does not have a complete flood management system, making it the only municipal-level city in Guangxi having no integrated management system. The flood control and drainage infrastructure in Hezhou is still very weak, with most of He River sections in the city having no dikes or embankment. Even for some of those in place, the flood control capacity is insufficient. The only dikes in place are the 965m long dike from Jiangbeizhong Road and Jianan Road to Shizigang Drainage Canal, the 764m long dike from Hezhou Bridge to Guidong Electrical Company, and the 2836m long dike (still under construction) from Guidong Electrical Company to Wayoutou Section. Without a sound dike system, Hezhou still has a long way to go to improve its flood management system. Built dike 1 Built dike 2 2.2.2 Current conditions of the drainage system Currently in Hezhou there are 98.63 km drainage pipeline in place in total, most of which are combined sewers system. This is because they are mostly built in the 1990’s when the design standards were not as strict as today. The storm water is mainly discharged to surrounding area through scattered ditches or pipes, mostly of small diameter of 300*300 or DN300. In addition, due to severe sedimentation, the drainage capacity of the pipelines is very limited. Without separate stormwater and sewage pipeline systems, a part of the domestic sewage, industrial wastewater and storm water are discharged directly into Huangansi River, Shizigang Drainage Canal or He River. During storm events, storm water and sewage overflow will occur due to limited drainage capacity, causing significant impacts on daily life and hygiene of local people. To the north of He River in the urban area, there are three major drainage canals, namely Huangansi Drainage Canal, Shizigang Drainage Canal, and Nanshetang Drainage Canal serving as the main drainage passage in the northern part of the City - 32 - and joining He River eventually. Huangansi Drainage Canal and Shizigang Drainage Canal run across the downtown area, receiving most of sewage before entering He River. The service area of Nanshetang Drainage Canal is currently a suburban area with much less sewage to receive. 2.2.3 Current conditions of rivers to be rehabilitated (1) Main watercourse of He River The main watercourse of He River to be rehabilitated in the Project is approximately 21.6 km long. The sections under construction include Beidi Park Section, Jiangnanzhong Road Section, Dongludi Dike Section and Pinggui Section in the upstream. With a ground elevation of 102.8 m to 117.5 m on both banks, the existing river banks are mostly farmland, bamboo forest or dry lands except the built area section that is protected with a vertical retaining wall. Most parts of He River bank are floodplain and Level 1 terrace. Photo No. 1 for current status of He Photo No. 2 for current status of He River River (1) Huangansi Drainage Canal The section of Huangansi Drainage Canal to be rehabilitated is 1.23 km long. It has vertical masonry retaining wall on both sides except the natural slope in only some individual sections. Both sides are crowded with residential houses. The terrain is relatively flat, slightly high in the north and low in the south with elevations ranging from 103.9 m to 105.2 m. The water quality of the canal gradually deteriorates from upstream to downstream along with the increase of sewage discharge. In the upstream sections, there is basically no siltation while in the downstream section siltation is as thick as 1.0m. Results of geological survey and drilling show that the bedrock in the Project is not deep and the Project is located within the area of karsts terrain. (2) Shizigang Drainage Canal The section of Shizigang Drainage Canal to be rehabilitated is 3.8 km long. There are artificial dike along the both sides of the canal with masonry retaining wall except in some parts there are natural slopes which are now used as gardens for local residents. The canal is narrow with shallow and black water. With open canal and - 33 - blind culvert each taking half of the canal, the canal involves thick sediments of 1.3 to 3.7m. Shizigang Drainage Canal Huangansi Drainage Canal (3) Lining River, Changlong River, Huangtian Branch Canal and Guposhan Drainage Canal The section to be rehabilitated is respectively 4.4km, 4.4km, 6.16km and 3.96km long for the planned Lining River, the planned Changlong River, Huangtian Branch Canal Guposhan Drainage Canal. The landform in the area is typical peak-forest eroded plain featuring a flat terrain high in the northwest and low in the southeast. Banks along the canals are mostly farmland or dry land, partly having exposed base rock, and the current ground elevation ranges from 111.5 m and 119.3 m. The canals are, in most of the sections, supported by vertical retaining walls, with only a very few parts being soil slope. With a very small width, siltation in these parts is not serious. (4) East Trunk Canal The section to be rehabilitated for Guishidong Trunk Canal is 9.89 km long and is located in the northern part of the project area. The upstream and midstream section of the canal belong to eroded terrace terrain while the downstream section belongs to peak-forest eroded plain and peak-forest depressions. The existing canal is supported by vertical and inclined retaining walls. Wider than the other canals, but without perennial flow, the canal does not involve siltation. On both sides of the canal are farm land and dry land. In the upstream section, deep soil slope is formed through back filling. Some sections of the canal are close to limestone hills. The terrain of most of the project area belongs to karsts terrain. - 34 - Lining River Changlong River Huangtian Branch Canal East Trunk Canal (5) East No.5 Branch Canal The diversion water gate for East No.5 Branch Canal is located at 43 + 075. It serves the irrigation needs for a land area of 24780 mu. The canal length is 11.78 km. The average flow at the start point and end point of the canal is respectively 1.8 m3/s and 0.7 m3/s. Jizishi Branch Canal is a branch of East No. 5 Canal starting at Xiwan Village and finally joining Huangansi River. The diversion water gate for East No.6 Branch Canal is located at 54+090. It serves the irrigation needs for a land area of 18130 mu. The canal length is 10.13 km. The average flow at the start point and end point of the canal is respectively 1.61 m3/s and 0.1 m3/s. Due to aging and improper maintenance, some urban sections of the canal are already damaged. Irrigation water can only be supplied from another branch canal. Water from the canal joins Ailian Lake in the end. - 35 - East No.5 Branch Canal 2.2.4 Current conditions of the hydropower stations to be upgraded (1) Huangshi Hydropower Station Huangshi Hydropower Station is located at Yangshou Town in Zhongshan County and is a run-off dam-type hydropower station. With the construction commenced in 1975, the hydropower station was completed and put into operation in 1978. It has a total installed capacity of 1000kW with 5 Nos. 200 KW generator units. The designed annual power generation capacity is 4.7 million KWh. The actual annual power generation is 4.3 million KWh. As a masonry gravity dam with a length of 100 m, a crest elevation of 109.00 m and a maximum dam height of 4.0 m, Huangshi Hydropower Station is currently operated and managed by Hezhou Huangshi Hydropower Station Co., Ltd. on behalf of Yangtou Town Government. Dam at Huangshi Hydropower Station Water Gate at Huangshi Hydropower Station (2) Fanglin Hydropower Station Fanglin Hydropower Station is located at 300 m upstream of the merging point of He River and Shatian River in the Pinggui District and is a run-off hydropower station. Adopting a masonry dam, the hydropower station dam is integrated with a 225m long, 11-span bridge across He River. 3 iron plate flap gates are installed for each span, - 36 - totally 33 such flap gate for the entire bridge. The flap gate has a top elevation of 105.00m. When flood comes, it pushes off the flap gate and is discharged, restoring He River bed to nearly its natural status. The Fanglin Hydropower Station (right bank) was built in 1971 with an installed capacity of 450 kw for 2 Nos. 100kW generator units and 2 Nos. 125kW generator units. In 2001, the hydropower station was transferred to and operated and managed by Hezhou Minfeng Industry Co., Ltd. Fanglin Hydropower Station (left bank) commenced construction in July 1987 and started operation in October 1988. With an installed capacity of 1000 KW for 5 generator units, the power station is currently operated and managed by Babu District Hydropower Engineering Machinery Construction Team. Dam at Fanglin Hydropower Station Gates at Fanglin Hydropower Station (3) Xiadao Hydropower Station Xiadao Hydropower Station is located on the section of He River at Xiadao Village of Ertang Town in Babu District located 4 km away from the city. As a river-bed power station located on the right bank, the hydropower station commenced construction in October 1967 and was put into operation in July 1972. At the beginning, it contained one irrigation water pump and one small hydropower station with an installed capacity of 535 KW and an average annual power generation of 4.59 million kWh. After several upgrades and expansion, the hydropower station has achieved an installed capacity of 6000kW and a total storage capacity of 7.07 million m 3 and become a multi-function hydropower station of power generation, irrigation and navigation with a multi-year average power generation capacity of 20.13 KWh. Originally a 95.5m long rubber dam, the dam has been converted into a flap gate dam. The current water level is 101.80m and the minimum water level is 95.50m. As the inflow gets to more than 586 m 3/s, the hydropower station will suspend power generation and all flap gates and sediment washing gates will be opened for flood discharge. Based on the analysis of the characteristics of the rated head of the hydraulic turbine on the premise that the water head and flow needed for full load power generation is satisfied, Xiadao Hydropower Stations should adopt the following operation mode: (1) The hydropower station will operate in normal mode when inflow is less than 180 m 3/s and the dam water level is - 37 - maintained at 101.80m (normal storage level); 2) Operation is suspended when inflow is greater than 180 m3/s but less than 400 m3/s.

It aims at solving the problem that the city has barely any flood control facility and has been suffering from flooding problems for long time, and at preparing the urban flood safety system, so that it can support the urban development in Hezhou. Its scope covers the area from the Liantang Township in the east, and to the Xiwan Street in the west, from the Etang Town in the south and to the Luoyang-to-Zhanjiang Railway in the north. The planed timeframe is to short term to 2020 and long term to 2030. The details of the plan the compliance analysis with the project are summarized in Table 2-6. - 71 - Table 2-6: Analysis of Compliance of the Project with Hezhou Municipality Urban Flood Control Plan (2015-2030) Compliance Item Planning This project analysis Based on the layout of He River and its tributary, and on the existing city layout and its expansion direction, the Plan proposed a flood control system that consists of three districts and seven sub-districts, including the Xiwan sub-districts and Pinggui sub-districts under the Pinggui District; the Shatian sub-districts, Jiangbei sub-districts, Jiangnan sub-districts, Liantang sub-districts under the Hezhou Core Urban District, and the Hejie sub-districts in Hejia Township. For each sub-district, the flood control The flood control standard for He River The project is in line standard is different based on its significance. The urban Overall under the Project is floods with a with Hezhou area along He River main watercourse will use once every layout recurrence period of 50 years. Municipality Urban 50 years reoccurrence frequency after regulation from Flood Control Plan upstream reservoir. For the urban area along the tributary (2015-2030) without upstream reservoir regulation, the standards of once every 20 – 50 years reoccurrence frequency will be used. In each sub-district, flood control dike will be built along He River and its tributaries including Xiwan River, Pangu River, Huashan River and Mawei River. Flood control gate and pumping stations will be built at the merging site of each outlet of drainage ditch and He Rivers.

The landfill will manly handle domestic solid waste from the downtown area of Hezhou Municipality (including Liantang Town and Hejie Town) and a part of the domestic solid waste from Pinggui District. The landfill occupies an area of 129,114 m2 and comprises of 2 landfill zones. Landfill Zone No.1 has a capacity of 370,000 m3 and a daily design treatment capacity of 180 t of domestic solid waste. 1 leachate treatment station as an associated facility has been constructed with a daily treatment capacity of 300 m3 . Landfill Zone No.2 has a capacity of 1.92 million m 3 and is not yet constructed. 2. Approval of Environmental Protection Hezhou Municipality Domestic Solid Waste Landfill was initially named as Guangxi Hezhou Municipality Domestic Solid Waste Harmless Disposal Plant. On October 30th, 2002, GZAR EPB issued approval for Guangxi Hezhou Municipality Domestic Solid Waste Harmless Disposal Plant Environmental Impact Assessment Report , and granted approval for the construction. On April 22nd, 2005, due to the big adjustment of treatment method and composition, at the 22nd executive meeting of Hezhou Municipality Government, the plant was renamed Guangxi Hezhou Municipality Domestic Solid Waste Harmless Disposal Plant from Hezhou Municipality Domestic Solid Waste Landfill. On May 9th, 2005, GZAR EPB issued approval for Hezhou Municipality Domestic Solid Waste Landfill Environmental Impact Assessment Report. In October 2017, Hezhou Municipality Babu District EPB issued approval for Hezhou Municipality Domestic Solid Waste Landfill Seepage Treatment Station Upgrading and Reconstruction Project Environmental Impact Assessment Report. 3. Status of Construction and Operation Construction of Hezhou Municipality Domestic Solid Waste Landfill No.1 was completed and put into operation in 2008. 4. Treatment Process and Standard Compliance Hezhou Municipality Domestic Solid Waste Landfill was put into operation in 2008. The selected solid waste treatment process is sanitary landfill and the leachate treatment process is “Biological Treatment + Flocculation and Sedimentation� . The treated leachate meets Class II standards specified in the Standard for Pollution - 84 - Control on the Landfill Site of Municipal Solid Waste (GB16889-1997). It is specified in Articles 9.1.2 - 9.1.3 of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008) that all existing and newly constructed municipal solid waste landfills shall meet water pollutants discharge limits in Table 2 starting from July 1st, 2009. After July 1st, 2011, all existing municipal solid waste landfills shall treat its own municipal solid waste leachate against the water pollutants discharge limits in Table 2. According to data of the conventional monitoring of the municipal solid waste landfill conducted by City Environment Monitoring Station in the recent 5 years, COD, BOD 5 and TN in treated leachate from Hezhou Domestic Solid Waste Landfill exceed the limits in Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008) (See details in Table 3.3 below). Therefore, Hezhou Domestic Solid Waste Landfill applies temporary measures for disposal of leachate by means of transporting the pretreated leachate in tankers to Hezhou Municipality WWTP for further treatment. Meanwhile, Hezhou Domestic Solid Waste Landfill conducted upgrading and reconstruction for solid waste leachate treatment station by relocating the leachate regulation tank from Landfill No.1 to Landfill No.2 where the leachate is treated with “Membrane Biological Reactor (MBR) + Nanofiltration (NF) + Reverse Osmosis (RO)� process.

Treatment Capacity Hezhou Municipality Domestic Solid Waste Landfill is currently using Landfill No.1 with capacity of 370,000 m3. As of September 2017, a capacity of 320,000 m3 has been used, with a balanced capacity of 50,000 m3. In the meanwhile, Hezhou Municipality Domestic Solid Waste Landfill, scheduled to be completed in December 2017, will upgrade and reconstruct the solid waste leachate treatment station by relocating the leachate regulation tank from Landfill No.1 to Landfill No.2, and using the former site of the leachate regulation tank as a landfill site (with a design capacity of 300,000 m3), making the total balanced capacity reach 350,000 m3. Calculated based on the existing solid waste delivery of 700 t/d, the future demand for 3 years will be satisfied. Sludge cake generated from dredging in the Project is 18,459 m 3, accounting for 5.3% of the total balanced capacity. Therefore, the capacity of Hezhou Municipality Domestic Solid Waste Landfill can meet the landfill demand of the Project. 6. Summary According to the due diligence conducted for Hezhou Municipality Domestic Solid Waste Landfill, the leachate discharged from the landfill does not meet standard limits listed Table 2 of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008), but the landfill is currently upgrading and reconstructing the leachate treatment station scheduled to be commissioned in December 2017. The subprojects of A-8: He River Main Watercourse Dredging, C-1 Huangansi Drainage Canal Rehabilitation and C-2 Shizigang Drainage Canal Rehabilitation will be implemented in 2018-2019 and the dewatered sludge to be generated from these subprojects will be disposed in Hezhou Municipality Domestic Solid Waste Landfill. Therefore, it is recommended that Hezhou Municipality Domestic Solid Waste Landfill should accelerate the reconstruction progress and implement the final acceptance of environment protection as a part of the final acceptance process according to the national and provincial regulations. In addition, after the Project is completed, the status of construction and operation of the Leachate Wastewater Treatment Station Upgrading and Reconstruction Project of Hezhou Municipality Domestic Solid Waste Landfill will be followed up with and the supervisory monitoring requirements included in the EIA of Hezhou Municipality Domestic Solid Waste Landfill will be incorporated into the Environmental Management Monitoring Plan of the Project, with its monitoring report regularly submitted as one of the mandatory deliverables of the Project. - 87 - 4.

The transportation system in Hezhou Municipality mainly comprises of highways and waterways. National Highway 207 and 323, as well as 3 provincial highways run through the city; Guilin-Wuzhou Expressway and Luoyang-Zhanjiang Railway Guangxi Section, Guangzhou-Hezhou Expressway also run across Hezhou Municipality, constituting a local transportation system “like five dragons flying towards the sea�. Hezhou Municipality has a total length of 2,543km for classified roads, including more than 300km for Class II roads. The percentage of high-class roads in the city’s road network is far much higher than the provincial - 91 - average of GZAR. With a road density 21.27km/100km2, Hezhou has basically achieved the goal of connecting every county to Class II roads, some towns and townships to asphalt pavement roads and every village to roads accessible to motorized vehicles. Waterway transportation mainly relies on Guijiang River and He River that joins Xijiang River and connects Wuzhou Port, providing a 1-day waterway access to Guangzhou, Hong Kong and Macau. 4.2.5 Landscape and Culture Relics (1) Landscape There are rich and beautiful scenic spots in Hezhou Municipality, which include natural landscapes such as Guposhan Mountain National Forestry Park, Hezhou Hot Spring, Yushilin, Ziyunxianjing and Bishuiyan Stone, etc. According to site investigations, The Project will not involve any scenic area, natural preservative zone or forestry parks and the project area are mainly farmlands or residential areas. However, due to frequent damage from flood on He River dike and littering and dumping of garbage into He River by riverside residents, parts of the project areas along He River are dirty and messy from the landscape view. (2) Physical Cultural Resources Hezhou boasts of rich reserves of cultural relics and simple but deeply-rooted folk customs. The Kirin Wine Vase (Qilinzun) a nationally-valued cultural relics (with a history of 2300 years from the Spring and Autumn period) was unearthed in Hezhou Municipality; the humane historical destinations include Shantianmafeng Wugui Bridge, Longjing Ancient Village, Zhuang Minority Cultural Village, and Local Yao Minority Cultural Park, etc,; the historical streets include Xiyue Street Historical and Cultural Quarter, Hedong Street and Xiwan Hydropower Station Street, and relics such as the Old Site of Babu Special Branch of the Chinese Communist Party (CCP). According to investigation, the components of He River Integrated Rehabilitation (Guangming Bridge – Lingfeng Bridge) and Huangansi Drainage Canal Rehabilitation under the Project will affect Xiyue Historical Cultural Street. He River Integrated Rehabilitation (Lingfeng Bridge – Xia Island Hydropower station) Project will affect the Old Site of CCP Babu Special Branch. 1.

Old Site of CCP Babu Special Branch The Old Site of CCP Babu Special Branch is located within Xiadao Primary School of Xiadao Village, Etang Township. As a representative building of the modern times constructed in 1943, the main school building is designed into a U-shaped plane with a north-facing gate. Nowadays, the teaching building has been destroyed, with only the school gate preserved. On its west, a “Memorial Hall of CCP Babu Special Branch� is constructed for exhibition of historical materials of CCP Babu Special Branch. The CCP Babu Special Branch has led the underground party work in Babu, Yongying, Guiling, Nanxiang and Pinggui mining area. The Old Site of CCP Babu Special Branch was back then a key activity base and is currently still an important red cultural heritage in Hezhou district and a base for patriotic education with important value for red cultural tourism development. 4.2.6 Local Drinking Water Sources According to the Letter of Approval by GZAR People’s Government on Classification Proposal Hezhou Urban Drinking Water Source Protection Zone (GZAR Guizheng Letter〔2016〕No. 203) issued in 2016, it has been approved to cancel the He River Babu Drinking Water Source Protection Zone and establish the Guishi Reservoir Drinking Water Source Protection Zone. The project area involves no drinking water source protection zone. 4.3 Status Quo of Ecological Environment 4.3.1 Status Quo of Constructional Land Use He River section included in the Project belongs to Babu-He Street Basin in terms of regional topography, with large tracts of farmland and village residential houses on both banks. In the basin, karsts topography is widely developed, creating a landform featuring in mountain peaks and woods valley, depressions and isolated peak plains. He River section of He River in Pinggui District is located in the leading edge of the He River first terrace. This curved river section has exposed sand and gravel on He Riverbed and shoals widely distributed in the upstream riverbed. Jiangbei dike in Babu District is located in the first terrace on the left bank of He River, with a bank base from He River Bridge to Guangming Bridge mostly comprising of farmland and dry land and the dike slope of bamboo revetment. He River section from Guangming Bridge to Babu Bridge is located in old urban area, with densely populated residential buildings and houses on both sides. and the existing dike slope is consisted of masonry retaining wall and bamboo revetment. He River section between Babu Bridge and Hezhou Bridge is new urban area, with an undulating terrain mostly covered by farmland and dry land. 4.3.2 Status Quo of Terrestrial Ecology Hezhou Municipality is located to the north of Tropic of Cancer and belongs to the subtropical monsoon climate zone. The area for evaluation is located in the urban area, where, due to long history of urban development, the primary ecological environment has been severely damaged, with no native vegetation and the existing vegetation being secondary natural vegetation or artificial vegetation. The natural - 98 - vegetation is divided into warm evergreen coniferous forest, limestone mountain deciduous broadleaf shrub and warm and hot grass, with majority of the vegetation warm evergreen coniferous forest and limestone mountain deciduous broadleaf shrub, and warm and hot grass as minor vegetation. Artificial vegetation consists of evergreen economic forest, paddy field and dry land, with mostly paddy field and dry land. The regional ecology system is mainly an agricultural ecosystem and forestry ecosystem and the quality of terrestrial ecology is average. Currently the majority of the tree species in the project evaluation area are common greening and landscaping plants such as bamboo and willow, etc., as well as crops. There are a small number of hydrophilic birds in the area. 4.3.3 Status Quo of Aquatic Ecology Here described as follows is the analysis and evaluation of the status quo of aquatic ecology in the He River Watershed introduced in the Report on Post Evaluation of the Ecological Impacts of Abrupt Environmental Incidents in He River (July 2013): 1. Phytoplankton In July 2013, a total of 40 Phytoplankton was monitored in He River, including 4 species of Cyanophyta, 1 Cryptophyta, 1 Euglenophyta, 1 Pyrrophyta, 10 species of Bacillariophyta and 23 species of Chlorophyta, which accounts for 10%, 2.5%, 2.5%, 2.5%, 25% and 57.5% of the total species, respectively, with Chlorophyta the highest proportion and Bacillariophyta the second highest. 2. Cell Density of Phytoplankton The total density of algae cells in He River Watershed is in the range of 5.54×105 ~ 1.16×107cells/L, Guishi reservoir has the highest density of algae cells. In all river sections in He River Watershed, Cyanophyta, Bacillariophyta and Chlorophyta have relatively high cell density; however, different species has different distributions at different monitoring sites. 3. Phytoplankton-based Water Quality Evaluation of He River Monitoring results at three monitoring sites at Guishi reservoir, the confluence of He River and Mawei River, and under Xindu bridge within the evaluation area show that the Shannon - wiener diversity indexes (H’) are all slightly lower than 3.0. According to the Phytoplankton biological diversity index, the aquatic ecological environment of He River Watershed is good. 4. Fishes The major economic fish species in He River Watershed are Crucian, Grass Carp, Sharpbelly, Southern quasi sharpbelly, Black Amur Bream, Catfish, Yellow catfish, etc., which are common in Guangxi and Guangdong Provinces, they are the major economic fish species. The major fish species for cage culture in this river section are Siniperca scherzeri, Spinibarbus denticulatus, Grass Carp and Yellow Catfish, etc. According to different living water layer for different fish species, the fish ecological groups of He River water system can be divided into following groups: Mid-upper layer group: Sharpbelly, Siniperca scherzeri, Rhodeus lighti, etc., these fish species are mainly living in the mid-upper layer of the stagnant water body during the non-winter season, often with the regularity of cluster activities. Mid-lower layer group: most of species under Carp, Crucian, Siluridae, Bagridae and - 99 - Xenocypris argentea Gunther and Leuciscinae. 5. “Spawning Grounds� Investigations of Fishes in the Project Watershed It has been observed through interviews with specialists in local fishery authority and site investigations that, since the water flow in the entire He River Watershed (Fujiang River to Yuhemianshi) is relatively gentle and slow, the annual net flow rate has an uneven distribution; due to relatively high-intensity development of this River Watershed, a number of large dams are built during the construction of hydropower stations, blocking the pass ways for fishes and their habitats; with the biological characteristics of He River fishes taken into account, there is no centralized large spawning ground in He River (Fujiang River to Yuhemianshi) basin, no spawning ground for large fish, and no spawning ground for fish that lays floating eggs such as grass carp, silver carp and bighead fish, and no small spawning grounds for fish that lays sticky eggs such as carp, crucian, catfish, etc. The overwintering ground for river fish is often in deep water. He River (Fujiang River to Yuhemianshi) is located in subtropical area, with relatively short low-temperature periods in winter. With the relatively shallow water depth and the interruption by large dams, He River has no overwintering ground for river fishes. The fish feeding ground is normally located where there is abundant food, He River (He Jiang River to Yuhemianshi) has dense population on both banks and rich aquatic-plants in midstream and upstream basin, providing abundant food for fishes. 4.3.4 Status Quo of Agricultural Ecology The major crops in the evaluation area include the common crops of rice, corn, Sanhua plum, water chestnut, tobacco and vegetables, etc. and there is no local special species. Rice is double cropping rice, part of which is used as dry crops and vegetables in winter season. 4.3.5 Status Quo of Soil Erosion According to Notice by GZAR People’s Government on the Zoning for Key Soil Erosion Prevention and Improvement Zones in GZAR (Guizhengfa〔2017〕No.5), Hezhou Municipality Babu District is one of the Key Soil Erosion Prevention and Improvement Zones while Pinggui District is not. The project area belongs to the southern red soil hilly area as a part of the Class II zones in the National Soil Erosion Classification Plan and the southeastern Gui low mountain area defined in the GZAR Soil and Water Preservation Planning and Zoning Program with a soil loss tolerance of 500t/(km 2·a). Investigation in the status quo in the project area shows that the type of soil erosion in the project area is mainly water erosion, in the form of surface scours and gully scours and the project area belongs to the slight-to-mild soil erosion area. The average soil erosion modulus background value in the project area is approximately 317t /(km 2 ·a). - 100 - 4.4 Status Quo Investigation and Evaluation of Environment Quality 4.4.1 Status Quo Investigation and Evaluation of Ambient Air Environment Quality According to the Technical Guidelines for Environmental Impact Assessment Atmospheric Environment (HJ2.2-2008), the project area mainly involves the urban area in Hezhou Municipality and its adjacent villages. Therefore, the conventional monitoring data from automatic monitoring stations in the city area is used for the analysis of the status quo of air environment quality in the project area. For the proposed WWTP, NH3, H2S, and odor concentration are added as the criteria of monitoring. Since the Project involves sediment dredging in He River course, which will cause odor emission, odor is sampled and analyzed based on the distribution of sensitive sites. The layout of the monitoring sites is shown in Figure 4-2. I. Ambient Air Monitoring of SO2, NO2, and PM10 Environmental Quality Weekly Report for Hezhou Municipality in Year 2017 (Issue No.24) published by Hezhou Municipal EPB is quoted for ambient air quality evaluation of the urban areas of Hezhou Municipality conducted under the Project. Details of the monitoring data are included in Annex Table 1. Analysis of the weekly monitoring data indicates that the monitoring factor AQI index at various monitoring sites in Hezhou urban area is generally in the range of 27~65, indicating that the air quality is good and the air quality at all monitoring sites meets Class II standard specified in Ambient Air Quality Standard (GB3095-2012).

Reference is made to the odor concentration limits specified in Class II standard indicated in Table 1 in the Integrated Air Pollutant Emission Standard (GB16297-1996). Results of this monitoring show that odor emission at Xiyue St. close to riverside residential areas along A7 Huangansi Drainage Canal dredging section and at Zhushan Rd. close to riverside residential areas along A8 Shizigang Drainage Canal dredging section exceeds the Class II standard indicated in Table 1 in the Integrated Air Pollutant Emission Standard (GB16297-1996) while the other monitoring sites meet the above standard. According to site investigation, due to historical reasons, no sewer pipe network was constructed at Huangansi and Shizigang Drainage Canal sections and domestic wastewater from residents along He River was directly discharged into He River course without any treatment, causing deterioration of the water quality and odor emission, and relatively high odor concentration in He Riverside residential areas. 4.4.2. Status Quo Investigation and Evaluation of Water Environment Quality According to the Environmental Impact Evaluation Technology Guidelines for Surface Water Environment (HJ2.3-1993), with the terrain features along He River taken into consideration, the Project involves the water systems of He River, Mawei River, Changlong River, Lining River, Shizigang River, East Trunk Canal, Dongwu Branch Canal, Huangansi Drainage Canal and Shizigang Drainage Canal. Status quo monitoring of water environment of the surface water in the region was conducted in July 2016 and May 2017 by a qualified monitoring unit authorized by the project owner while the monitoring data and results of Babu District EPB for key rivers in Babu District are quoted for the status quo of water quality in Mawei River.

Soil in Hezhou Municipality is mainly developed from quaternary red clay, which belongs to the karsts landform and limestone substrate is distributed in a certain proportion. Therefore, the background value of heavy metals is relatively high. According to 2014 Report on Soil Environment Quality Monitoring in Areas around Centralized Drinking Water Sources in Hezhou Municipality, the soil monitoring results at Hezhou Babu water intake point (the water intake located at 600m upstream of Guangming Bridge in Hezhou Urban area has already been cancelled) indicate that arsenic exceeds the standard by a factor of 1.70-7.30, implying that the background values of heavy metal factors in soil in the project area in Hezhou are relatively - 118 - high. The results of this monitoring process further demonstrate that the background values of arsenic, cadmium and mercury in soil in the project area are high. 4.4.5 Investigation and Evaluation for Existing Condition of Sediment Environmental Quality 1.

In summary, the monitoring items of zinc, cadmium, arsenic and mercury at He River sediment monitoring sites in the Project are found unexceptionally exceeding Class III standard specified in the Environmental Quality Standard for Soils (GB15618-1995) . Standard noncompliance for heavy metals is relatively severe at Shizigang Drainage Canal, Huangansi Drainage Canal and upstream of Fanglin Hydropower Station dredging section. - 123 - Analysis of causes for standard noncompliance: (1) According to the analysis in section 4.4.4, the background values of arsenic, cadmium and mercury in the soil in the project area are relatively high. (2) Hezhou Municipality has rich mineral resources. With more than 60 proven mineral resources in its territory, Hezhou is known as the largest white marble mine in central and southern China and ranks the first in terms of the reserves of tungsten, tin, rare earth, veneer granite, and silicon stone in GZAR. Hezhou has a long history of mining and long-term scattered and small private mines have been the cause of direct discharge of untreated wastewater from mine pit, mining selection, metallurgical refinery and tailings into He River course. As a result of lasting accumulation of heavy metals and discharge into He River, heavy metal content in river sediment is found exceeding the standard. 6. Identification of Leaching Toxicity In order to identify the sediment leaching toxicity and determine if the sediment is hazardous, monitoring was carried out for the sediment leachate based on Identification Standards for Hazardous Wastes - Screening Test for Leaching Toxicity (GB5085.3-2007). The monitoring items include lead, cadmium, mercury, arsenic and Chromium 6. Monitoring results are listed in Table 9 as attached. According to monitoring data, Lead, Cadmium, Arsenic, Mercury, Chromium 6 in sediment leachate are all within the concentration limits for hazardous chemicals specified in Identification Standards for Hazardous Wastes (GB5085.3-2007), thus not belonging to hazardous waste, and can be disposed according to Standard for Pollution Control of Sites for Storage and Disposal of General Industrial Solid Wastes (GB18599-2001). 4.5 Pollution Sources in the Project Area Situated at midstream and downstream of He River, Hezhou Municipality has rich water resources, which is the strong support for its industrial and agricultural development. Along with the acceleration of urbanization, discharge of domestic wastewater is increasing each year. At river sections near the urban area, in dry season, large amount of domestic sewage is directly discharged into He River, forming a pollution belt along He River. The estuaries of Huangansi Drainage Canal and Shizigang Drainage Canal at the northern part of city are the largest discharge outlets in urban area while the inland rivers accept wastewater along the urban section of He Rivers and finally join into He River. 4.5.1 Investigation on pollution sources of He River and its tributaries According to site investigation and in association with the investigation materials on the existing condition of He River urban section pollution sources conducted by Hezhou Municipal EPB, there are the following pollution sources for the urban section - 124 - of He River. The section from Fanglin Hydropower Station to Xiadao Power Station has a total length of 11km and there are a total of 44 stormwater and wastewater discharge outlets along He River. 2 of these outlets are industrial wastewater discharge outlets, namely, the Ecological Industrial Park discharge outlet and Guidong Electronics industrial wastewater discharge outlet (the two enterprises have self-built wastewater treatment stations and the effluent meets Integrated Wastewater Discharge Standard Class I standard before discharge into He River); the other 42 discharge outlets are combined sewer outlets (one of which is a temporary domestic wastewater treatment facility effluent outlet for Jiangnan District, which mainly collects domestic sewage from Jiangnan District and treats wastewater to meet Class I standard specified in the Integrated Wastewater Discharge Standard before discharged into He River; the rest of the outlets are all for direct discharge of wastewater). The main discharge outlet into He River urban section are Shizigang Drainage Canal, Huangansi Drainage Canal and the effluent outlet of Hezhou Municipal WWTP, accounting for 51.9% of the total discharges. Due to large flow in He River, the natural treatment capacity is high and currently, the water quality in He River urban section still meet Class III standard for surface water quality. River Watershed of Mawei River is located in an agricultural farming area, with agricultural pollutants along He River flowing into He River with rainfall. Therefore, the NPS pollution is the main pollution source. Currently, land is undeveloped on both sides of He River and water quality in Mawei River meets Class III standard for surface water quality. 4.5.2 Water Quality Pollution is Severe in Inner Rivers According to Investigation Report on Black and Odorous Water Bodies in the Urban Area of Hezhou Municipality, He Rivers where black and odorous water bodies are found in Hezhou urban area are mainly the downstream section of the main watercourses of Shizigang Drainage Canal and Huangansi Drainage Canal as well as their tributaries on the east side. Due to historical reason, the control width of Shizigang and Huangansi Drainage Canals are relatively narrow within the project area and the flood control feature is difficult to achieve. In addition, there is no reserved regulation volume at the upstream sections and waterlogging can easily occur once there is a storm. Shizigang Drainage Canal is already channelized. Huangansi Drainage Canal is the largest pollutant discharge outlet and there a large number of residential buildings along He River in the urban area, with combined domestic wastewater and stormwater collected, conveyed and discharged in combined sewers into He River. The east tributaries join the main watercourse at Gong Bridge Health Clinic and enter the densely populated residential area. Domestic wastewater directly discharged from the residential areas along He River is the main pollution source. Meanwhile, there are extensive farmland and residential areas surrounding the upstream of Huangansi River, with lotus root and rice as the major crops. Agricultural fertilizer and chemical residues flow into Huangansi River with - 125 - surface runoff, causing extensive discharge of pollutants. In the meanwhile, decomposed organics from crops such as lotus root and rice also flow into Huangansi River along with surface runoff. The water quality in He River is worse than Class V water quality, causing severe black and odorous water body. Shizigang Drainage Canal is the major drainage canal and one of the pollutant discharge outlets in urban area. There a large number of residential buildings along He River in the urban area, with combined domestic wastewater and stormwater collected, conveyed and discharged in combined sewers into He River. The water quality in He River is worse than Class V water quality, causing severe black and odorous water body. Changlong River and Huangtian Branch Canal are for agriculture irrigation. However, since He River Watersheds are located in undeveloped urban area, large area of farmland and few residents are located along He Rivers, due to the underdeveloped infrastructure in the area, Changlong River and Huangtian Branch Canal serve as the drainage canal for the industrial and domestic wastewater along He Rivers and the water quality in He River is worse than Class V. Artificial water diversion canals in Hezhou Municipality urban area include East Trunk Canal and Dongwu Branch Canal. The water supply is mainly diverted from Guishi Reservoir and used for irrigation along the canal. Land use along the canal mainly include farmland and dry land, with agricultural pollutants discharged into the canal along with rainfall, making NPS pollution as the major pollution source in this watershed. - 126 - 5. Environmental Impact Assessment and Mitigation Measures 5.1 Environmental Impacts and Mitigation Measures during Construction Based on the nature of project activities, environmental impacts for the construction period and operation period are identified respectively. Construction activities that will generate environmental impacts include earth excavation, earth and construction material transportation, watercourse widening, dike construction, dredging, hydropower station improvement and construction of WWTP and associated pipeline networks. Therefore, major environmental impacts during construction include soil erosion caused by excavation, exhaust emission and noise from transportation of earth and construction material on construction site and construction access roads, and wastewater discharge from construction camp and sediment dewatering facility and odor from dredging and temporary storage of dredged sediment. Additionally, social impacts include disturbance to local traffic by construction vehicles and Fanglin Hydropower Station improvement, impact to physical cultural resources (Xiyue Block and The Old Site of CCP Babu Special Branch) by He River rehabilitation, interference with railway from river-lake connection, and impact on existing farmland irrigation by Fanglin Hydropower Station improvement. Environmental impacts during construction will be assessed in these aspects. Particularly, as dredging will affect multiple environmental elements such as ambient air and water, dredging impacts and mitigation measures will be analyzed in a separate subsection. 5.1.1 Soil Erosion Analysis and Mitigation Measures 5.1.1.1 Analysis of Soil Erosion Impact (i) Causes of Soil Erosion Vegetation will be removed in the process of construction site clearing, leveling, watercourse widening, road construction and pipeline construction. Excavation of drainage foundation trench will lead to temporary earth storage; excavation and backfilling associated with watercourse and pipeline construction will change original landform and generate new unstable slope without vegetation. Affected by the aforesaid construction activities, surface erosion and gully erosion will be caused by rain in the project area. (ii) Environment Impact of Soil Erosion (a) Increased turbidity and impacts on water quality of the rovers Soil will directly enter He River in the process of watercourse excavation and lead to high turbidity of river water and deteriorated water quality, if construction is not under good management. Waste soil generated from dike construction, site excavation or - 127 - road construction will flow into He River through stormwater runoff and affect water quality especially in strong wind and heavy rain, if the soil is not cleaned in a timely manner or not properly covered. (b) Loss of Land Vegetation, Decreased Land Production and Degraded Ecology Affected by soil erosion associated with construction site clearing, surface runoff will carry more suspended solids, inorganic and organic substances into He River and cause degraded water function, adverse impact on aquatic environment for water supply and inconvenience of daily life of local residents. Decreased land production, degraded water body function and deteriorated ecological environment caused by soil erosion will hinder sustainable economic development in surrounding area. 5.1.1.2 Result of Soil Erosion Prediction Prediction indicates that construction of the Project will disturb land area of 399.88 hm2 and damage water and soil conservation facility of 294.38 hm2. Quantity of waste soil that requires for permanent disposal is 1,273,400m 3. Soil loss during construction will total 136,787 tons. . Occurrence of soil erosion concentrates in construction period and concentrates in construction site of He River rehabilitation, temporary soil storage site, borrow area and waste soil disposal site. 5.1.1.3 Water and Soil Conservation Zone and Measures (i) Water and Soil Conservation Zone The water and soil conservation zone of the Project is divided into four Class 1 conservation zones, namely, flood risk control construction zone, urban drainage improvement construction zone, water quality improvement construction zone and temporary construction zone.

The IAs will provide resettlement compensation in cash and will work with local governments to make proper arrangements in accordance with concerned policies to ensure livelihood of the relocated residents to avoid social issues. Details of social impacts and mitigation measures associated with land acquisition and resettlement are given in Section 8 of this report and Resettlement Action Plan of the Project. 5.1.2.2 Impact on Railway Operation Safety and Mitigation Measures Dongwu branch canal and Lining River, under Improving Urban Drainage and - 135 - Wastewater Management component, cross existing Gui-Guang high-speed railway. As required by urban area flood control safety program, rehabilitation of Dongwu branch canal and Lining River will be needed as below: Jacking of two-hole culvert with size of 3.0 m in width, 2.2 m in height and 26 m in length will be done at intersection of Dongwu branch canal and Gui-Guang high-speed railway, located at DW0+628 to DW0+655. Construction platform is 40 m in length and 11 m in width, located at DW0+588 to DW0+628. Affected width of culvert jacking is same as width of the construction platform. Jacking of three-hole culvert with size of 3.7 m in width, 2.0 m in height and 122.5 m in length will be done at intersection of Lining River and Hezhou Railway Station, located at LN1+025 to LN1+147.5. Construction platform is 140 m in length and 16 m in width, located at LN0+885 to LN1+025. Affected width of culvert jacking is same as width of the construction platform. In accordance Regulation on Railway Transportation Safety Protection, the DI is coordinating with the railway authority, Nanning Railway Bureau, and the final construction program will be approved by Nanning Railway Bureau before put into implementation. 5.1.2.3 Impact on Public Traffic and Mitigation Measures Soil, construction material (sand, cement) and waste soil storage and transportation during construction will increase local traffic flow, occupy existing road, and cause traffic congestion and access difficulty. Pipeline construction has significant impact to local traffic. Temporary earth storage associated with pipeline construction during construction will have significant traffic impact. Open excavation for laying road-crossing wastewater interception pipelines will interrupt road traffic and cause significant traffic impact. Construction activities that affect daily life of the residents include foundation excavation, excavation and pipeline laying, backfilling, and road excavation and occupation, which will reduce urban road surface, decrease traffic capacity, lead to road blockage and congestion, traffic inconvenience of local residents, and also will affect social economy to some extent. Particularly, occupation of school access road will cause access difficulties of students, school staff and parents and may affect access safety of the students and normal school activities, including Hezhou College, Pinggui No.3 Middle School, Hezhou Pilot Middle School and Xiadao Primary School in urban area. Rehabilitation of Fanglin Hydropower Station includes improvement of existing river-crossing gate dam (combination of gate dam and bridge) and connection of bridge approach and upstream and downstream dike. Fanglin Bridge will be closed during construction in order to ensure construction and traffic safety, and access of nearby residents in Fanglin Street and Tianchang Village south to Fanglin Bridge will be affected. The following measures should be taken to avoid public traffic impact caused by - 136 - construction activities: 1. For construction activities that will affect public traffic, construction program should be provided to public traffic authority in advance for arrangements for adjusting public traffic route, and construction cannot commence until permission is obtained. 2. Signs should be set on construction site before construction indicating construction description and schedule, requesting public understanding of inconvenience caused by construction activities, and disclosing contact information and complaint hotline. This information could be disclosed in advance through media, micro-blog and wechat, as possible. 3. Excavation and backfilling should be done by zone. 4. Temporary access roads should be built when construction site is near public facilities like bus stop. Material transportation should be scheduled to avoid peak hours to reduce peak traffic volume. Separate construction access road should be built for construction in rural area to avoid use of rural road and damage of rural road by oversize equipment and vehicle. 5. Pipeline construction should avoid peak hours or traffic diversion and adjustment should be done by traffic police in peak hours to mitigate traffic congestion and ensure convenience of pedestrians to minimize traffic impact to local residents. 6. Training on construction management and environmental protection should be strengthened. For construction near school, traffic diversion and adjustment should be done by traffic police in peak hours of the school, and temporary traffic lights and other signs should be set. During construction of Fanglin Hydropower Station improvement, travel from Fanglin Street and Tianchang Village to area north of He River will be re-routed along Fanglin Road, G207 and Sanjia Bridge or through Mintian rural road and Bahuang Class 2 road. Traffic re-routing plan is subject to approval of traffic police and road closing and re-routing signs will be posted. 5.1.2.4 Impact on Underground Pipelines Foundation excavation may interfere with existing underground pipelines and damage of existing pipelines will affect daily life of the residents. Based on existing pipeline survey, existing pipelines that will be possibly affected by project construction activities are listed in Table 5-1.

The contractor should further coordinate with municipal and urban development authorities during construction for collection of underground pipeline information including pipeline type, alignment and depth, and establish pipeline coordination team. Prior approval should be obtained from municipal and urban development authorities for excavation interfering with underground pipelines. 2. Construction plan and emergency response plan should be developed based on pipeline alignment and depth to avoid interference with existing underground - 139 - pipelines as much as possible. 3. In the event of interference with existing pipelines, the concerned authority should be informed of particular construction location and schedule of excavation activities to be prepared for emergency responses. 5.1.2.5 Impact of Fanglin Hydropower Station Improvement on Irrigated Area and Mitigation Measures Based on investigation, Fanglin Hydropower Station has irrigation function to some extent. Relying on high water level contributed by barrage, river water can flow to irrigation channels through diversion culverts by gravity. Irrigation area of Fanglin Hydropower Station covers about 400 mu dry and paddy field in Tianchang Village, 200 mu farmland in Mintian Village and 1,000 mu farmland in Fanglin Village on the right bank. Crops on the farmland include corn, rice, peanut, sweet potato, vegetable and water chestnut. As water level will decrease due to removal of gate dam during Fanglin Hydropower Station improvement and river water cannot flow to the farmland by gravity, farmland irrigation of Tianchang, Fanglin and Mintian villages will be affected. In order to ensure normal irrigation of paddy and dry farmland in Tianchang, Fanglin, and Mintian villages on the right bank, project design includes new construction of a small-sized irrigation lift station with cost of CNY 4 million. River water will be lifted by three pumps with designed delivery head of 30 m and distance of 800 m and diverted to irrigated area in Tianchang, Fanglin and Mintian villages through existing water diversion culverts and channels. 5.1.2.6 Impact of Covered to Open Canal and Mitigation Measures Rehabilitation of Shizigang Drainage Canal includes the restoration of existing covered canal into open canals. The precast slabs covering the existing canal under Yinhe Street will be removed; parking lot of Hezhou Municipal Land Resources Bureau will be partly excavated; pavement of the internal roads in the sites of the office and staff dormitory buildings of Guidong Power Company will be demolished to restore the covered canals with a length of 350 m, 100 m and 150 m respectively at these sites into open canals. Buildings/structures affected are temporary shops constructed over the precast-slab covered canal on Yinhe Street, existing parking lot over the covered canal in the Land Resource Bureau office area, and office and staff dormitory buildings and roads of Guidong Power Company. During the restoration of the covered canals to open canals, traffic on major roads in this area will not be interrupted, including Badaxi Road, Jianshezhong Road, Pinganxi Road and Jianshedong Road. During construction, residents in Yinhe Street have to make a detour of 100 m to Badaxi Road to cross the canal, and internal access in residential area of Guidong Power Company will be affected and Jianshedong Road will be relied on as before for going out. Business of shops in Yinhe Street will not be restored after change of the canal, and income of the shop owners will be affected. Part of the parking lot of Hezhou Municipal Land Resources Bureau will not be restored, and the - 140 - resulted gap of parking space will be filled up by diverting traffic, restricting access of vehicles from other organizations and taking advantage of the surrounding parking lots. For the sake of traffic accessibility for residents of Yinhe Street, Hezhou Municipal Land Resources Bureau and Guidong Power Company, it is considered in technical design that a small-sized river-crossing bridge is built for each of Yinhe Street, Hezhou Municipal Land Resources Bureau and Guidong Power Company. Impacts on normal operation of Yinhe Street shops, Hezhou Municipal Land Resources Bureau and Guidong Power Company will be mitigated through resettlement compensation, and details are given in Resettlement Action Plan of the Project. 5.1.2.7 Community health The Project involves 22 construction camps in the construction process and these construction camps will host approximately 60 to 80 persons in the peak period.The planned construction camps are mostly located in open spaces in the outskirt or on the river banks, with Shizigang Construction Camp No. 1 as an exception located in the downtown area; a certain distance has been considered in the planning from the construction camps to the residential areas. In the camps, simple barracks will be constructed to provide shelter for construction workers and the construction camps will be fenced up to form a relatively enclosed and independent space so as to minimize flow of people and contact between construction workers and community residents. Therefore, in the construction stage of the Project, the construction workers will have little communication and contact with local community in Hezhou and the risks of community health will also be relatively insignificant. Analysis shows that the construction workers of the Project are mainly local people and only a limited number of non-local workers are needed. Therefore, with the small number of non-local workers, the Project will not incur problems of increase of population due to the immigration of families of the construction workers and thus brings no pressure on the community service. China has relatively comprehensive laws and regulations on labor and various criminal offenses (e.g. sexual harassment, etc.) and strict law enforcement. The overall social security condition in Hezhou is fine and the community is harmonious. In summary, the negative impacts likely to arise from the construction workers of the Project on the local community will be very insignificant. In order to safeguard community health and prevent negative impacts on local community by the construction workers, the following measures should be taken: (1) Basic hygienic facilities should be provided in the construction camps and managed with greater efforts to avoid spread of diseases. (2) All efforts should be made to control the scale of Shizigang Construction Camp No. 1 and a certain distance should be kept from the construction camp site to the residential areas. Local workers should be employed to the best possibility. - 141 - (3) Education on laws, social security and traffic safety should be organized for the workers to promote their awareness of safety. (4) Health education should be organized for workers to increase their knowledge of HIV and other infectious diseases and encourage them to take protective measures and avoid spread of diseases to others by using condoms. (5) Education on environmental protection should be organized for the workers to assure that the ESMP requirements are followed for disposal of wastewater and solid wastes on the construction camps to prevent spread of diseases. 5.1.3 Environmental Impacts of Dredging and Sediment Disposal and Mitigation Measures 5.1.3.1 Dredging and Sediment Dewatering Methods and Disposal method Different dredging methods are selected based on size of water body. For He River that has wide water surface and large quantity of dredged sediment, cutter suction dredger is selected. Dredged sediment is treated at No.1 and No.2 dewatering facilities located along He River into sludge cake with 50% moisture content. Dewatering effluent is discharged back to He River. Huangansi and Shizigang Drainage Canals have a worse water quality and stinky sediment due to domestic sewage received along the canal throughout the year. These two canals are located in densely populated urban center with limited operation space. Therefore suction pumping plus manual excavation is selected for dredging. Dredged sediment with a 95% water content will be hauled by fecal suction trucks to No. 1 dewatering site located along He River. The sediment will be dewatered to sludge cake with 50% moisture content, and the effluent is discharged to He River. Mechanical excavation supplemented by manual excavation is chosen for dredging of Huangtian Branch Canal, Guposhan Drainage Canal and East Trunk Canal. These canals are surrounded by farmland and unused land with adequate operation space, therefore onsite movable vehicular dewatering facility is used and effluent is discharged back to the canals. Interception and diversion + dry dredging may be used as the dredging method for the inner rivers of Shizigang Drainage Canal and Huang’ansi Drainage Canal provided that the construction condition (the space of operation is available for interception and diversion of the inner rivers) is available and a sound regional intercepting pipeline network is in place. Dredging methods, siting of sediment dewatering facility and final disposal methods for He River and its tributaries are shown in Table 5-2. - 142 - Table 5-2 Dredging and Sediment Disposal Methods for He River and Its Tributaries Implementation Quantity of Surrounding Dredging and Dewatering Disposal Subcomponent River/Canal Time Dredged Sediment environment Transportation Method Location method Sediment from Lingfeng Bridge 156,900 m3 (water section to No. A-8 The main content 95%), 1 dewatering The main Cutter suction dredger + Solid watercourse of equivalent to 15,690 site, and watercourse 2018-2019 Urban Area dewatering facility at Waste He River m3 sludge cake with Sediment of He River dewatering site Landfill Dredging 50% moisture from Fanglin content Bridge section to No. 2 dewatering site 8,800 m3 (water content 95%), Manual operation + sludge C-1 Huangansi Huangansi Adjacent to To No. 1 Solid equivalent to 880 m3 pump + fecal suction truck + Drainage Canal Drainage 2018-2019 Residential dewatering Waste sludge cake with No. 2 dewatering site at Rehabilitation Canal Area site Landfill 50% moisture dewatering site content 3,300 m3 (water content 95%), Manual operation + sludge C-2 Shizigang Shizigang Adjacent to To No. 1 Solid equivalent to 330 m3 pump + fecal suction truck + Drainage Canal Drainage 2018-2019 Residential dewatering Waste sludge cake with dewatering facility at Rehabilitation Canal Area site Landfill 50% moisture dewatering site content - 143 - Table 5-2 Dredging and Sediment Disposal Methods for He River and Its Tributaries Implementation Quantity of Surrounding Dredging and Dewatering Disposal Subcomponent River/Canal Time Dredged Sediment environment Transportation Method Location method 7,440 m3 (water content 95%), Manual operation + B-5 Huangtian Huangtian No Solid equivalent to 744 m3 Farmland, mechanical excavation + Branch Canal Branch 2020 dewatering Waste sludge cake with Unused Land bankside vehicle-mounted Improvement Canal site is needed Landfill 50% moisture drying equipment content 3,540m3 (water content 95%), Manual operation + B-6 Guposhan Guposhan No Solid equivalent to 354 m3 Farmland, mechanical excavation + Drainage Canal Drainage 2020 dewatering Waste sludge cake with Unused Land movable vehicle-mounted Improvement Canal site is needed Landfill 50% moisture drying equipment content 4,610 m3 (water A-4 East Trunk content 95%), Manual operation + Canal No Solid East Trunk equivalent to 461 m3 Farmland, mechanical excavation + Rehabilitation 2022 dewatering Waste Canal sludge cake with Unused Land movable vehicle-mounted and Connection site is needed Landfill 50% moisture drying equipment with Mawei River content - 144 - Dredged sediment has a water content as high as 95% or more, and dewatering is required. Movable vehicular dewatering facility is used for East Trunk Canal, Huangtian Branch Canal and Guposhan Drainage Canal, and sediment dewatering is done along the canal. As Huang’ansi Drainage Canal and Shizigang Drainage Canal both flow through the densely populated urban area and connection of fecal suction truck and vehicular dewatering facility may cause sediment leakage and spill, a fixed sediment dewatering site is required. The advantage of fixed dewatering facility is the easy implementation of retaining, covering, interception, odor removal and ground cleaning measures. Two fixed dewatering facilities are set for preliminary drying of sediment from He River, Huang’ansi Drainage Canal and Shizigang Drainage Canal. Dewatering Facility No.1 (located on flood land along He River about 100 m upstream of Lingfeng Bridge) and Dewatering Facility No. 2 (located on flood land along He River about 100 m upstream of Fanglin Bridge) cover a land area of approximately 500 m2 each and are equipped with temporary sediment storage tank, dewatering operation area, interception channel and wastewater collection tank. Sediment monitoring results given in Section 4 show that the monitored values of arsenic and cadmium in the sediment of He River and the urban inland canals could not meet Environment Quality Standard for Soil (GB15618-1995) Class III limits for normal agricultural and forest production and plant growth, therefore the dredged sediment is not suitable for application to forest land or dry farmland. Based on investigation there are no any other sediment disposal methods in Hezhou City such as incineration facility or co-incineration cement kiln, therefore dewatered sediment will be hauled to Hezhou municipal solid waste landfill for disposal. Sludge cake will be transported in closed vehicle to the landfill for disposal. Transportation route from No. 1 dewatering site to solid waste landfill covers distance of about 14 km through south Lingfeng Road, G207, Gongye Road, G323, and landfill access road. Transportation route from No. 2 dewatering site to solid waste landfill covers distance of about 18 km through Fanglin Road, Guangming Road, G207, Gongye Road, G323, and landfill access road. Transportation route is selected to minimize environmental impacts by avoiding densely populated area and shortening transportation distance. Locations of dewatering facilities and transportation routes are demonstrated in Figure 5-1. - 145 - Figure 5-1: Schematic Diagram of Sludge Dewatering Sites and Transportation Routes - 146 - 5.1.3.2 Ambient Air Impact of Dredging and Sediment Dewatering and Mitigation Measures Dredging methods with less ambient air impact are selected through comparison of alternatives during design. For example, cutter suction dredger is selected for He River dredging andsuction pump selected for urban river dredging. In the underwater dredging, the water seal has effective control of odor emission and can significantly reduce odor generated in the process of sediment agitation. Meanwhile, dredging is scheduled in autumn and winter with low temperature and organic substance fermentation rate, which will generate less odor emission compared with dredging in summer and minimize odor impact from the source. Moreover, doors and windows of residential buildings in densely populated area along Huang’ansi Drainage Canal and Shizigang drainage canal are usually closed in autumn and winter, which will weaken direct impact of dredging odor to residents. For sections of Shizigang Drainage Canal that will be changed from covered to open canal, residents of Yinhe Street, staff in Land Resources Bureau and Guidong Power Company office buildings and residents in residential area of Guidong Power Company will be directly affected by odor emission once canal cover is removed. Odor impact will be greatly mitigated through scheduling construction activities in autumn and winter. Dredged sediment with a water content of 95% from He River, Huang’ansi Drainage Canal and Shizigang Drainage Canal will be hauled to dewatering facilities No.1 and No.2 for dewatering. Temporary sediment storage in dewatering facility will generate odor emission, and analogical method is adopted for analysis of odor pollution intensity. Dry-method dredging of Mudanjiang City Nanpaozi Lake is used as reference, as the way of odor generation is similar of dry-method dredging and temporary sediment storage process in terms of direct sediment exposure to air. Analysis of odor intensity is showed in Table 5-3. Table 5-3 Odor Intensity of Mudanjiang Nanpaozi Lake Dry Dredging Distance Odor Intensity Level Bankside Significant Level 3 30 m away from Bank Insignificant Level 2 80 m away from Bank Very Insignificant Level 1 More than 100 m away No Level 0 from Bank Analogical analysis indicates there will be significant odor next to temporary sediment storage tank, and odor intensity will decrease to Level 2 at 30 m away, better than odor intensity standard limit of Level 2.5 to 3.5. There will be almost no odor 50 m away from the storage tank. Dewatering facilities are located along He River, and environmental sensitive receptors are avoided during site selection. Distance between dewatering facility and the nearest sensitive receptor is more than 100 m, therefore temporary sediment storage in dewatering facility will not have impact on environmental sensitive receptors. Sludge cake with moisture content of 50% should be transported out in a timely - 147 - manner, and quicklime and deodorant should be supplied for site disinfection and odor removal. In addition, personal health protection supplies should be provided to construction workers to effectively mitigate impact of odor. 5.1.3.3 Impact of Dredging and Dewatering on Water Environment and Mitigation Measures Environmental-friendly and mature cutter suction dredging method is used for The main watercourse of He River. Suspended solid concentration around the cutter suction dredger will increase to some extent during dredging, but the coarse particles will settle rapidly after the fine particles are sucked up to the dredging boat. Moreover, as He River has large water flow and diluting capacity, small scope of sediment disturbance will not deteriorate water quality. Huang’ansi Drainage Canal, Shizigang Drainage Canal, East Trunk Canal, Huangtian Branch Canal and Guposhan Drainage Canal have small quantity of dredged sediment, but the canals are quite narrow and cutter suction dredger is not suitable for dredging. Sludge suction pump or mechanical excavation has advantage of flexible operation and slight disturbance to river water quality. Therefore, impact of dredging on water environment is temporary, and river water quality will be improved as large quantity of substrate pollution sources are removed and organic pollutant release is greatly reduced. Dredged Sediment with water content of 95% from He River, Huang’ansi Drainage Canal and Shizigang Drainage Canal will be transported to No.1 and No.2 dewatering sites located along He River for dewatering. Stormwater leaching and river water scouring may cause generation of muddy runoff during temporary sediment storage and secondary pollution to He River. Additionally, dewatering effluent still contains suspended solids and organic pollutants although majority of the solids has been intercepted by dewatering, therefore wastewater treatment facility is required on sediment dewatering site. (a) Interception ditch surrounding the temporary sediment storage tank will be built to divert wastewater to sedimentation tank; (b) Stormwater and dewatering effluent collected in the interception ditch should be treated in wastewater sedimentation tank before discharged to He River; and (c) Sediment should be dewatered and hauled out of the site in a timely manner to avoid generation of leachate from storage of large quantity of sediment. 5.1.3.4 Impact of Dredged Sediment and Disposal Measures Dredging methods, siting of dewatering facilities and final sediment disposal methods for He River and its tributaries are shown in Table 5-2. Dredged sediment with water content of 95% will be dewatered In an integrated drying facility to sludge cake with moisture content of 50%. Sludge cake should be transported out of site for disposal in a timely manner to avoid stormwater erosion or river water scouring and secondary pollution to surface water. Retaining, covering and interception measures should be taken to effectively mitigate impact of sediment leakage and overflow. Additionally, quicklime and deodorant should be provided for odor removal. - 148 - Following project implementation schedule, quantities of sludge cake with moisture content of 50% from sediment dredging and dewatering of He River, Huang’ansi Drainage Canal and Shizigang Drainage Canal are 15,690 m3, 880 m3 and 330m3 respectively. Implementation period of East Trunk Canal, Huangtian Branch Canal and Guposhan Drainage Canal rehabilitation is 2020 to 2022, and quantities of sludge cake with moisture content of 50% will be 744 m3, 354 m3 and 461 m3 respectively. Sludge cake will be hauled to Hezhou solid waste landfill for disposal. Currently capacity of zone 1 plus capacity contributed by original adjustment tank of this landfill can meet demand for solid waste disposal of Hezhou City in the coming three years and can also accommodate disposal of sludge cake from the Project. 5.1.4 Impact of Noise and Mitigation Measures 5.1.4.1 Analysis of Construction Noise Construction noise is generated by construction machine and transportation vehicle. Construction noise occurs in a certain period, temporarily and not in fixed locations. Noise varies with construction machine. Intensity of major noise sources is projected in Table 5-4. Table 5-4 Noise Level of Major Construction Machines Noise Level/dB (A) (5 m away from the SN Construction Machine machine） 1 Loader 90 2 Truck 87 3 Pump 80 4 Vibrator 79 5 Bulldozer 90 6 Excavator 83 7 Sludge Suction Pump 80 As shown in Table 5-4, operation of multiple machines at the same time will lead to superposition of noise level. According to the prediction, it is estimated that the superimposed noise level will increase by no more than 3 dB(A). As shown in Table 5-5, noise level of construction machine decreases with distance. Table 5-5 Prediction of Noise Level Varying with Distance Unit: dB (A) Intensity of Distance (m) Construction Noise Source Machine 15 30 50 80 100 150 200 300 500 (Distance: 5m) Loader 85 75.5 69.4 65.0 60.9 59.0 55.5 53.0 49.4 45.0 Truck 87 77.5 71.4 67.0 62.9 61.0 57.5 55.0 51.4 47.0 - 149 - Pump 80 70.5 64.4 60.0 55.9 54.0 50.5 48.0 44.4 40.0 Vibrator 79 69.5 63.4 59.0 54.9 53.0 49.5 47.0 43.4 39.0 Bulldozer 85 75.5 69.4 65.0 60.9 59.0 55.5 53.0 49.4 45.0 Excavator 83 80.2 74.2 69.7 65.6 63.7 60.2 57.7 54.2 49.7 In accordance with Hezhou Urban Area Environmental Noise Standard Application Zoning, the Project is located in Class II area and applicable standard is Acoustic Environment Quality Standard (GB 3096-2008) Class 2 with a noise limit of 60 dB (A) for daytime and 50 dB (A) for nighttime. Major construction plants include excavator, bulldozer, loader, vibrator and dump truck with an operation noise level ranging from 80 to 90 dB (A). Prediction results in Table 5-5 show that impact of excavation noise is within 150 m during daytime and 500 m during night at places there is no any sound barrier between noise source and receptors. Noise level can be reduced by 15-25 dB (A) when temporary hoarding and sound barrier are installed, and noise level at environmental sensitive receptors caused by construction equipment will range from 54 to 60 dB(A) after mitigation measures are taken, which meets Environmental Quality Standard for Noise (GB3096-2008) Class 2. Benefited from noise buffering by the first row residential buildings, the second row residential buildings are almost not affected by construction noise. In this case, noise impact during construction concentrates on area within 30 m of the construction site. Sensitive receptors within 30 m of the construction site are listed in Table 2-4. Particularly, more stringent noise reduction measures should be taken to mitigate impact of construction noise on Hezhou College, Hezhou Pilot Middle School, Pinggui No.3 Middle School and Xiadao Primary School. Construction activities should be prohibited during normal school time to avoid disturbance. 5.1.4.2 Noise Impact Mitigation Measures The ESMP includes common practices to mitigate noise impact by better managing construction activities such as earth excavation, earth and material transportation and construction of buildings and structures. Major mitigation measures include: (1) Advanced and reliable low-noise equipment should be selected. (2) Construction period is from 8:00 to 20:00, with construction activities being suspended from 12:00 to 14:00 for noon break. Construction activity during night is allowed only when permission is obtained from construction authority and approved by local EPB and disclosed to nearby residents. (3) Construction activities should be reasonably scheduled avoiding operation of multiple high-noise machines at the same time and on the same construction site. Construction period should be shortened as possible to minimize noise impact on construction workers. (4) Vibration damping foundation or support should be used for machines that generate high noise, including use of damping material. - 150 - (5) Noise from transportation vehicle will affect sensitive receptors along the route to some extent. The contractor should improve environmental awareness of the construction workers, understand local folk custom and habit, and carefully schedule transportation time and limit vehicle speed and prohibit use of horn in environmentally sensitive area such as densely populated area. (6) The contractor should consult with nearby agencies, residents and schools, and arrange construction activities with high noise in summer and winter vacations and holidays as much as possible. Meanwhile, construction should be accelerated to shorten construction period. High-noise construction activities should be concentrated in weekends to minimize impact on nearby sensitive receptors. (7) High-noise construction plants should be located on the construction site far away from residential area. 1.8m high hoarding for noise reduction should be installed on construction site located within 5 m of residential area. (8) The contractor should have reasonable construction staffing to shorten working time of workers that operate high-noise machine. Earmuff should be provided to construction workers to reduce noise impact. (9) All the construction equipment should be maintained on a regular basis to keep them in good condition, reduce noise and prolong operation life. (10) Stringent requirements should be made for construction scheduling, machine and vehicle operator and operation practice. Particularly, temporary sound barrier not lower than 2m and with good noise reduction effect should be installed on construction site near Hezhou College, Hezhou Pilot Middle School, Pinggui No.3 Middle School and Xiadao Primary School., and construction during normal school time should be avoided. 5.1.5 Impact on Physical and Cultural Resources and Mitigation Measures Rehabilitation of He River (Guangming Bridge to Lingfeng Bridge), rehabilitation of Huang’ansi Drainage Canal and construction of Huangansi stormwater pump station will possibly affect ancient wharf and city wall in Xiyue historical and cultural block. This project will do nothing to the ancient dike other than backfilling and compression outside the ancient wharf and city wall to ensure dike stability. Landscaping construction will be combined with flood control dike outside existing Babu river dike to demonstrate prosperous shipping culture of Hezhou City in old time with the subject of “silk road on the sea and thousands of boats racing across He River�. Meanwhile, corridor frameworks are designed to hide vertical flood control gate. In order to protect memorial hall and old school gate of The Old Site of CCP Babu Special Branch that may be affected by He River rehabilitation (Guangming Bridge to Lingfeng Bridge), project scope has been optimized in the design stage to avoid protected area of Xiyue historical and cultural block and new buildings and structures are designed in consistent style with existing historical and cultural block. - 151 - Embankment design has been revised by changing the originally-designed T-shaped revetment to vertical retaining wall to avoid interference with the Old Site of CCP Babu Special Branch. Uncontrolled construction activities and weak relics protection awareness of the construction workers may lead to damage to structure of the relics and pollution, and the damage may be irremediable. Therefore, physical and cultural resources management plan included in the ESMP specifies major measures for construction activities concerning physical and cultural relics as below: (1) Protective Measures for Xiyue Historical and Cultural Block (i) Protection of existing river dike and ancient wharf, construction of ancient-style recreational waterside bridge and corridor, and construction of wastewater interception pipelines along He River; (ii) Training on Historical and Cultural Relics Protection Law and local regulations on historical and cultural relics protection should be provided to the construction team before site mobilization, in order to increase historical and cultural relics protection awareness of the construction workers; (iii) Local historical and cultural relics authority should be consulted by the IA prior to construction and realistic relics protection program should be developed; (iv) Detailed construction program should be prepared before construction activities commence. Relics protection signs should be posted on construction site providing information of nature of the relics, importance, protected scope, protection measures, and contact person and channel of the historical and cultural relics authority; (v) Safety and stability of the relics in construction area should be ensured. Site safety rules and operation practice should be prepared based on concerned national laws and regulations and various requirements by the IA should be followed, to make sure relics will not be damaged or stolen; (vi) Manual excavation should be adopted in protected scope of the relics instead of use of excavator and piling machine to minimize vibrating impact; (vii) Setting of construction camp or temporary surface soil storage site should be banned within protected scope of the relics; (viii) Oversize vehicle and equipment are not allowed to enter protected scope of the relics; (ix) Relics protection training should be provided to the construction workers by contractor. Construction activities should be kept far away from the relics as possible to avoid damage to the relics; (x) In the event fossil, ancient coin, valuable article, ancient structure and other relics of geological or historical significance are found during construction, construction - 152 - activities should be stopped immediately and this should be promptly reported to construction supervisor, the IA and local relics protection authority. Effective measures should be taken to protect the site and construction activities should not continue until permission is obtained from local authority; and (xi) Knowledge of physical and cultural resources should be delivered to Xiyue Street residents for them to understand historical and economic value of these relics and get involved in physical and cultural relics protection and development of protection plan and regulations. (2) Protective Measures for the Old Site of CCP Babu Special Branch (a) Local historical and cultural relics authority should be consulted by the IA prior to construction and realistic relics protection program should be developed; (b) Training on Historical and Cultural Relics Protection Law and local regulations on historical and cultural relics protection should be provided to the construction team before site mobilization, in order to increase historical and cultural relics protection awareness of the construction workers; (c) Detailed construction program should be prepared before construction activities commence. Relics protection signs should be posted on construction site providing information of nature of the relics, importance, protected scope, protection measures, and contact person and channel of the historical and cultural relics authority; (d) Safety and stability of the relics in construction area should be ensured. Site safety rules and operation practice should be prepared based on concerned national laws and regulations and various requirements by the IA should be followed, to make sure relics will not be damaged or stolen; (e) Manual excavation should be adopted in protected scope of the relics instead of use of excavator and piling machine to minimize vibrating impact; (f) Setting of construction camp or temporary surface soil storage site should be banned within protected scope of the relics; (g) Oversize vehicle and equipment are not allowed to enter protected scope of the relics; (h) Relics protection training should be provided to the construction workers by contractor. Construction activities should be kept far away from the relics as possible to avoid damage to the relics; and (i) In the event fossil, ancient coin, valuable article, ancient structure and other relics of geological or historical significance are found during construction, construction activities should be stopped immediately and this should be promptly reported to construction supervisor, the IA and local relics protection authority. Effective measures should be taken to protect the site and construction activities should not continue until permission is obtained from local authority. - 153 - 5.1.6 Impact on Ambient Air and Mitigation Measures Major air pollution source during watercourse widening, construction of drainage gates, pump station and water replenishing canal improvement, construction of road and pipelines is dust caused by open excavation, which includes dust from earth excavation, onsite storage and backfilling, dust suspension caused by people and vehicles, as well as transportation vehicle leakage. Transportation vehicle is the major source of construction dust. Construction access road of 80.9 km will be built, 65.4 km of which will be rebuilt and maintained as embankment road and the remaining 15.5 km access road will be restored once construction is completed. Moving vehicle wheels generate dust, especially heavy vehicle that generates more dust. Vehicle moving faster generates greater quantity of dust. Meanwhile, dust generation is related to physical condition of road surface and cleanness condition. On fully dry road surface, dust generated can be calculated by the following empirical formula:  0 Q.   V 123 5W6 8 . P5 0 . . 85 0 0 . 75 Where: Q - Quantity of dust from vehicle moving, kg/km/vehicle V - Velocity, km/h； W - Weight, ton P - Quantity of dust on road surface, kg/m2 Under normal meteorological condition, dust generation by a 10 ton vehicle driving through 1 km road surface with different cleanness degrees and under different driving velocities is given in Table 5-6. Table 5-6 Dust Generation Varying with Driving Speed and Road Surface Cleanness Unit: kg/km/vehicle Pkg/m2） Velocity 0.1 0.2 0.3 0.4 0.5 1.0 （km/h） 5 0.051 0.086 0.116 0.144 0.171 0.287 10 0.102 0.172 0.232 0.288 0.342 0.574 15 0.153 0.258 0.348 0.432 0.513 0.861 20 0.204 0.344 0.464 0.576 0.684 1.148 30 0.306 0.516 0.696 0.864 1.026 1.722 Table 5-6 indicates that vehicle that moves faster generates more dust under the - 154 - same road surface cleanness condition, and dirty road surface causes more dust when vehicle speeds are the same. Analogy analysis shows that impact of the dust generated by construction site and transportation road under natural wind condition is confined to the scope within 50 km. 4 to 5 times of water spraying on the road during construction will reduce dust suspension by approximately 70%. Speed limit and keeping road clean are effective measures for reducing dust caused by vehicles. Dust control measures, such as watering on and covering of onsite lime, soil and sand as well as construction debris, should be taken. Transportation of construction material and waste soil should be covered and should not be overloaded. Vehicle wheels should be cleaned before the vehicle leaves construction site, and leakage and spill should be avoided. Environmental sensitive receptors within 50 m along the transportation route are listed in Table 2-4 (Distribution of Environmentally Sensitive Sites). He River dredging and river and lake connecting subcomponents have many sensitive receptors and APs that are mostly located within a distance of 50 m from the project area. ESMP provides necessary construction practices for better management of excavation, soil and material transportation and building/structure construction to minimize dust impact. Major mitigation measures include the following： (a) Construction site management should be strengthened. Transportation vehicle should be in good condition and should not be overloaded for cement and lime transportation, and covering and enclosing measures should be taken to avoid spill and reduce dust generation. Reasonable locations should be selected for material and waste soil storage, and material such as cement and lime should be stored at the same area and wind protection and covering measures should be taken. Sand screening and cement bag opening should be done in the lee, and site that has significant dust generation should be installed with windbreak facilities. (b) Clean-up and water spraying can be done for dust control on construction site and road. Spraying water 4 to 5 times each day on construction site is suggested. Practice in China concluded that Integrated Air Pollutant Emission Standard (GB16298-1996) can be met by adopting these mitigation measures, in terms of concentration of uncontrolled emission of particulates. Damaged vegetation should be restored in a timely manner. (c) Transportation vehicles should be cleaned and washed in a timely manner before leave construction site. Wheel washing equipment should be provided on site to clean earth on the wheels. (d) Onsite fume control should be enhanced. Toxic fume and gas emission is prohibited on construction site to mitigate waste gas pollution to sensitive receptors. (e) Stringent site management measures should be taken, which include installation of hoarding not lower than 2 m along both sides of construction site, enclosed construction, containment structure installed at hoarding bottom with no space between hoardings and between hoarding and containment structure, and setting of - 155 - No-entry signs for banning non-construction workers to enter the site. (f) Loading/unloading and transportation process should be strictly managed. Transportation of sand, cement and waste soil should be covered, and construction material should be loaded and unloaded carefully. (g) Temporary storage of earth and sand during construction should be covered and watered, and should be hauled out of the site as early as possible. (h) Start-up frequency of fuel powered machine should be minimized to effectively reduce exhaust generated by construction plants. (i) Transportation vehicle and construction equipment should be properly maintained to keep normal operation and avoid more exhaust emission caused by improper maintenance. Use of equipment that significantly violates applicable emission standard should be banned. 5.1.7 Impact on Water Environment and Mitigation Measures 24 construction sites and camps are set in total. Storage of construction material such as asphalt, fuel and chemicals should be properly managed and be covered as necessary to avoid water environment pollution to He River and its tributaries caused by stormwater runoff in rainy season. Oily wastewater during construction is generated from leakage and spill in the process of construction equipment repair and maintenance, which includes lubricant, diesel and petrol and may pollute water body. This type of wastewater is characterized by small quantity and greatly varying concentration and very limited scope affected. Proper measures should be taken by the contractor to prevent potential water pollution. Large amount of construction workers will be required during construction, which are mostly local workers and will generate certain quantity of domestic sewage. As most of construction areas are located in built urban area, existing municipal infrastructure and sanitation facilities can be used for treatment of domestic sewage of the construction workers and no separate facilities are needed. Where municipal infrastructure and sanitation facility are absent in construction area, necessary environmental protection facilities should be provided or mitigation measures should be taken. Hydropower station improvement have potential surface water pollution caused by dike construction, drilling debris associated with hydropower station foundation construction, construction wastewater (drilling wastewater, oily wastewater) and disturbance to local water by dredging activities. The ESMP includes common practices for management of construction activities to mitigate impact on water environment, and major measures to be taken include the following: (a) Sand and stone processing wastewater should be treated in sedimentation tank, and the effluent should be reused for concrete production and dust control rather than discharged into nearby water body. Construction slurry should be pumped into sedimentation tank for treatment and drying through evaporation. Construction - 156 - machine cleaning wastewater should be treated in oil separation and sedimentation tanks and the effluent should be reused for dust control and vehicle cleaning. (b) Siting of construction site should fully accommodate need for drainage and should be far away from water body. Construction site, warehouse, and diesel and asphalt storage site as well as asphalt making facility should not be located within 500 m of He River. Necessary measures should be taken to prevent discharge of pollutants into He River, especially through stormwater runoff in rainy season. (c) Operation area should be kept clean during construction to prevent discharge of wastewater and pollutants into the open channel and penetration. (d) In the event onsite oil fuel storage is required, anti-seepage measures should be adopted for storage and use to prevent oil leakage and spill and water pollution. (e) Foundation construction should be done in non-rainy days as much as possible to minimize impact on construction activities due to shallow groundwater level. (f) Water-related construction such as hydropower station and dredging should be done in dry season as much as possible, and construction period should be shortened as possible to reduce disturbance to water body. (g) Personal protective equipment and life-saving appliance should be provided to prevent accident. (h) Domestic sewage and solid waste collection and treatment facilities should be provided in construction camp without centralized municipal facilities. Domestic sewage can be discharged to nearby farmland as fertilizer, after treated. 5.1.8 Impact of Solid Waste and Mitigation Measures Solid wastes during construction are mostly contributed by removal of existing river dams of Fanglin and Huangshi power stations, demolition of buildings acquired, construction of new structures (sand and stone, lime, concrete, timber, waste brick, and earth) as well as domestic solid waste generated by construction workers. Construction solid waste will total 99,100 m3 and will be hauled to municipal construction solid waste landfill in Huangtian Town Gonghe Village for disposal. In addition, hazardous waste such as waste oil may enter surface water and cause water quality pollution if storage and transportation is not properly managed. Therefore, management measures should be enhanced in response to possible generation of hazardous waste, which include provision of special container for collecting waste oil from equipment maintenance and repair and provision of onsite emergency-responsive box, sand or saw powder for absorbing waste oil. Based on earth balance analysis, during construction the Project will have excavation of 3,433,500 m3, filling of 5,451,500 m3, reuse of 59,100 m3 excavated earth, 3,291,400 m3 earth from external source, and final disposal of 1,273,400 m3 (184,600 m3 sediment will be dewatered and hauled to Hezhou municipal solid waste landfill for - 157 - disposal, 556,400 m3 will be transported to Hezhou City electronic technology ecological industrial park for lowland filling, and 532,400 m3 will be hauled to the disposal site of the Project). Two borrow areas have been selected for the Project. One borrow area is located 1,000 m east to Hezhou City electronic technology ecological industrial park. This borrow area occupies 16.85 hm2 hilly land covered mostly with grass and eucalyptus. The other borrow area is located 750 m west to Gongye Road and 100 m north to G207 road, occupying 20.1 hm2 hilly land covered mostly with grass and eucalyptus. One disposal site will be set southwest to Donglu Village and 500 m south to Guang-He Highway, covering total land area of 7.40 hm 2. This disposal site will receive residual surface soil, unusable earth and stone, and soft earth. Water and soil conservation and restoration measures for borrow area and disposal site are described in Section 5.1.1 5.1.9 Ecological Impact Analysis and Mitigation Measures 5.1.9.1 Impact on Terrestrial Ecosystem and Mitigation Measures The project area is located in the built urban area or city outskirt without native vegetation. Ecosystem in the project area is composed of urban ecosystem and farmland ecosystem. Vegetation along He River mainly comprises of bamboo forest and bushes, and vegetation along urban inland canals comprises of farmland crops, aquatic plants and artificial secondary forest. Rehabilitation of He River will affect habitat of some waterside birds. Survey shows major bird species frequently found along He River include partridge, cuckoo, drongo cuckoo and oriental skylark, which are all ordinary species. Construction will damage vegetation habitat, and the direct result of vegetation damage will be land bareness, and greater water and wind erosion. Furthermore, modified ecosystem structure and function will lead to deterioration of regional ecological environment. Movement of construction plants and workers during construction will significantly damage vegetation on construction site. Therefore, necessary environmental protection measures should be taken during construction for effective control of impact of construction activities on local vegetation. For example, scope of construction activities should be narrowed and construction period should be shortened as much as possible, and vegetation should be restored once construction is finished to minimize local ecological impact. Construction activities will disturb inhabitation and breeding of waterside bird species along He River, but ecological system along He River will be restored after construction and will be improved over time. After implementation of the Project, introduction of variety of local plant species that are adapted to local condition will not only increase number of regional plant species and population and vegetation coverage, but also will improve environmental quality and provide better condition for normal growth of plants. Survey results indicate that 15 ancient and rare trees are distributed in Xialiang - 158 - Village, Middle Jiangbei Road, Xiyue Street, Xinaner Street, Xinanyi Street and Jianshezhong Road along He River are not within the construction area of the Project, but quite near the construction site, approximately 50 m away from the site. Normal growth of these trees will possibly be affected by earth taking and disposal, storage of construction solid waste, moving of construction vehicles and transportation of construction equipment, therefore attentions should be paid during construction and the following protective measures should be taken. 1. Construction scope should be narrowed and construction period should be shortened as much as possible; 2. Tree felling, unauthorized transplanting, bark peeling, root digging and injection of toxic and hazardous substances to trees should be prohibited; 3. It is not allowed to construct buildings or structures, lay pipelines, install power cables, excavate borrow areas, mine sand and stone, flood or seal the ground, emit fumes, discharge wastewater and dump solid wastes, stockpile or dump flammables, explosives or toxic and hazardous substances in the area with a distance of less than 5m from the outer edge of the crown shadow of trees. 4. It is not allowed to engrave, nail, wind, hang or support or stack articles on or around tree trunks; and 5. Construction vehicles and plants are not permitted to enter or roll the area with a distance of less than 5m from the outer edge of the crown shadow of trees. 5.1.9.2 Impact on Aquatic Ecology and Mitigation Measures Water-related construction activities and dredging may affect aquatic ecosystem of He River and its tributaries. Ecological survey reveals all the aquatic animals in He River are ordinary species, and there is no fish spawning field, feeding field, winter habitat or rare aquatic animal species in He River. He River dredging covers a river length of 3.6 km. Small-scope of water-related hydropower station improvement and dike construction are scheduled in dry season. Huang’ansi Drainage Canal, Shizigang Drainage Canal, Huangtian Branch Canal and Guposhan Drainage Canal are all located in urban area with intensive human activities, and major functions of these canals are flood discharge and providing water for irrigation purpose. Polluted by domestic sewage, these canals have deteriorated water quality and severe sediment deposit. Major aquatic plant species is green alga, and benthos organism is ordinary benthos species. There is no fish spawning field, feeding field, winter habitat or rare aquatic animal species in these canals, and none of these canals is important natural habitat. Water-related construction and dredging will result in disappearance of some benthos lives, but this will be restored over time after dredging is finished. Therefore, implementation of the Project will have insignificant impact on aquatic life and will not degrade or modify ecology of He River and urban inland canals. - 159 - 5.1.10 Conclusion of Dam Safety Assessment and Action Plan World Bank Safeguard Policy OP/BP 4.37 for dam safety is triggered by the Project.

City 175 5.2 Analysis of Environmental Impacts in the Operation Stage This Project includes three components, namely, Improving He River Flood Risk Resilience, Improving Urban Drainage and Wastewater Management, and Institutional Capacity Building and Project Management. Once completed, the Project will improve the urban flood control capacity, mitigate local water pollution, increase landscaping value, improve ecological environment, and improve municipal infrastructure of Hezhou Municipality. Adverse environmental impacts include effluent, odor and noise generated by Jiangnan WWTP operation and noise generated by stormwater pump stations. As a whole, the Project will have significant benefits and insignificant adverse impacts. 5.2.1 Analysis of Environmental Benefits during Operation 5.2.1.1 Change of Hydrological Condition and Flood Control Benefits (i) Change of He River Hydrological Condition and Flood Control Benefits In the watercourse widening works under the Project, the natural gradient of the main watercourse of He River will be maintained and sections with uneven riverbeds and serious sedimentation (e.g. the section upstream of existing hydropower station) will be dredged without widening of the main river channel. Water flow of He River is determined by precipitation and catchment area that are not changed due to the implementation of the Project. Therefore, the Project will not result in changes of the water flow of He River. As the main water channel will not be widened, the hydrological conditions such as the water velocity and flow rate in normal and dry seasons will not change. Hydrological modeling analysis is conducted over the relationship between inundation loss and engineering investment under different flood control standards. Results of such analysis show that the most cost effective scenario will be achieved when flood control system is designed against the flood control standard for floods with a recurrence period of 50 years for main watercourse and floods with a recurrence period of 20 years for tributaries. The DHI-MIKE series software is used for modeling analysis and the actual topographic map is used, with the engineering design and inflow locations of each sub-catchment area on the main watercourse identified. Based on the finalized center line of the main watercourse, a hydraulic model is developed for He River and its tributaries to evaluate urban area inundation and economic loss under the applicable flood control standards and determine the technical design and mitigation measures. Modeling calculation indicates that, when flood is controlled within the main channel, the regional flow section will decrease from the urban area floodplain section to the main channel section under the scenario of designed flood level. Peak flood flow and velocity in main watercourse will increase by approximately 10%, compared with existing peak flood in urban area floodplain section. As an emerging tourism city, rapid development of various infrastructures in Hezhou - 176 - City will increase risk of regional soil erosion. The slightly increased river course scouring impact due to the increased peak flow and velocity after rehabilitation will be mitigated by sand control using adjustable power station flashboard. Meanwhile, revetment construction, vegetated revetment, ecological swale and other structural measures, planting measures, temporary protective measures will be taken to prevent soil erosion and form an integrated and scientific soil erosion prevention system and reduce sand discharge into He River. Analysis indicates that, without rehabilitation of He River and its tributaries, the flooded area and average flooded depth of Hezhou urban area will be 13.10km 2 and 1.23 m respectively under floods with a recurrence period of 50 years. The flooded area is mainly located in the middle reaches of He River mostly occupied by residential buildings, hospital and school buildings between Guangming Bridge and Lingfeng Bridge on the left bank of He River. The total floor area of the flooded buildings and farmland area will be 3.22 km 2 and 9.88 km2 respectively, causing economic loss of approximately CNY 2.044 billion. Main watercourse will be improved through dike and revetment construction, river dredging and hydropower station improvement. The dike and revetment construction includes the construction of a multi-functional dike of Xiyue Street section and dikes of other river sections. River dredging covers an 2km long river section upstream of Fanglin Hydropower Station and the 1.6 km long river section upstream and downstream of Lingfeng Bridge. Hydropower station improvement includes upgrade of Huangshi, Fanglin and Xiadao power stations. These rehabilitation measures will increase flood discharge capacity of main river course and avoid flooding of urban area. The flood control capacity of Hezhou Municipality is improved through the promotion of the flood control standards of both the main watercourse and the tributaries. Improvement of flood control capacity of the main river course alone will have the flood control standard promoted to the level for floods with a recurrence period of 50 years and reduce the flooded urban area by about 9 km2 or 68.7% and economic loss by approximately CNY 1.70 billion or 83.2%, thus capable of safeguard the flood safety in the urban area to a large extent. (ii) Change of Urban Canal Hydrological Condition and Flood Control Benefits Rehabilitation of urban inland canals will be done through river/lake retention, water diversion and discharge measures. Jintai Lake and Yongfeng Lake will be used for retention of regional peak flood flow to release pressure on downstream river course. Jintai Lake and Yongfeng Lake have a retention capacity of 300,000 m3 and 590,000 m3, respectively. Huang’ansi Drainage Canal is only used for discharge of stormwater within its own catchment area, and water received from upstream will be diverted to Shizigang Drainage Canal. Stormwater lift stations will be built at Huangansi and Shizigang canal estuaries to lift stormwater of urban area to river when He River is at high water level. River rehabilitation will eliminate inundation occurrence in urban area under 1-in-20 years precipitation and ensure urban safety. Meanwhile, river-lake connection, and water diversion and water replenishment will increase water flow as a - 177 - whole, increase assimilative capacity of urban inland canals and help improve water environment. Under scenario of rehabilitation of He River and without rehabilitation of its tributaries, flooded area and average flooded depth of Hezhou urban area will be 3.10 km 2 and 1.07 m respectively under floods with a recurrence period of 20 years. Flooded area concentrates in lower-elevated area along Huangansi and Shizigang canals occupied by residential buildings, hospitals and schools, especially protected Xiyue historical and cultural block located downstream of Huangansi canal. Total flooded floor area of the buildings and farmland area will be 0.38 km 2 and 2.72 km2 respectively, causing economic loss of approximately CNY 250 million. 5.2.1.2 Benefits of Water Environment Improvement The existing urban rivers in Hezhou City are mostly natural channels with low drainage capacity and without efficient management. Major issues include small discharge section, serious sediment deposit and the resulted weak flood discharge capacity. Uncontrolled wastewater discharge along Huang’ansi Drainage Canal, Shizigang Drainage Canal, Huangtian Branch Canal and Guposhan Branch Canal has resulted in deteriorated water quality and occupied or covered watercourse. The Project intends to address the problems of restricted space of watercourse, inflow of wastewater from both banks and water-human separation. This Project will follow the water system planning and implement ecologically-friendly river rehabilitation and river section determination on the basis of the existing water surface ratio. Service roads will be built along He River and trees and grass will be planted as the boundary line of He River channel. Wastewater will be intercepted along He River in dry season and Jiangnan WWTP and associated pipeline networks will be built to increase wastewater collection rate, reduce pollutant loading into He River, and finally improve water quality of He River. (i) Benefits of River-Lake Connection, Water Diversion and Wastewater Interception River-lake connection is favorable for the establishment of an urban river system and replenishment of fresh water. The first major source for water replenishment is Xitiankou Water Diversion Canal that diverts water from Mawei River with maximum diversion flow of 2.0 m3/s. The other source is Wugongshui Water Diversion Canal that diverts water of Xiwan River with maximum diversion flow of 1.51 m 3/s. The standby source for water replenishment is Guishidong Trunk Canal that diverts water from Guishi Reservoir. Regular renewal of river and lake water achieved through river/lake connection will help improve self-purifying capacity of water body, prevent occurrence of water body eutrophication, ensure landscaping water use requirements being met by artificial lake, and ensure water quality will not deteriorate through regular renewal. Wastewater interception along He River will greatly reduce pollutant load discharged into He Rivers and improve river water quality. Based on catchment area, quantities of wastewater intercepted will be 4,300 m3/d along Huang’ansi Drainage Canal, 6,500 - 178 - m3/d along Shizigang Drainage Canal, 1,600 m3/d along Huangtian Branch Canal, and 2,600 m3/d along Guposhan Drainage Canal, respectively. Wastewater interception totals 15,000 m3/d along the four urban rivers. Treatment of wastewater intercepted in Hezhou municipal WWTP will reduce pollutant loading into He River in terms of COD, BOD, SS, TN, NH3-N and TP by 1888.88 t/a, 903.38 t/a, 1231.88 t/a, 328.5 t/a, 221.75 t/a and 3 t/a, respectively. Pollutant load reduction benefits are significant. (ii) Benefits of Pollution Reduction by the WWTP After the Project is fully completed, water quality of He River and its tributaries will be improved. This project will have significant benefits in improving flood control and aquatic environment. Operation of Jiangnan WWTP will greatly reduce pollutant load into He River, as shown in Table 5-9. Table 5-9 Pollutant Load Reduction by WWTP Operation Pollutant Influent Pollutant Effluent Pollutant Concentration Capacity Load Facility 3 Pollutant Quality Load Quality Discharge Decrease （m /d） Reduction (mg/L) (kg/d) (mg/L) (kg/d) (mg/L) (kg/d) COD 280 4200 50 750 230 3450 BOD 120 1800 10 150 110 1650 Jiangnan SS 160 2400 10 150 150 2250 15,000 WWTP TN 55 825 15 225 40 600 NH3-N 32 480 5 75 27 405 TP 5.5 82.5 0.5 7.5 5 75 Table 5-9 indicates that operation of Jiangnan WWTP will reduce the inflow load of COD, BOD, SS, TN, NH3-N and TP respectively by 1259.25 t/a, 602.25 t/a, 821.25 t/a， 219 t/a，147.83 t/a and 2 t/a, respectively, generating significant benefits in reduction of pollutant load. (iii) Benefits of River Dredging Surface substrate structure on He Riverbed will become more stable after dredging, helpful to increasing DO concentration, change redox reaction condition of bottom interface, and reduce release of nutrients. River dredging will effectively remove a considerable part of nitrogen, phosphorus and heavy metal; with wastewater intercepted along the major drainage canals, the waterfront pollution belt will be significantly reduced. The main watercourse of He River will become unobstructed and freeflowing to facilitate sand sedimentation, decrease water turbidity, and increase intensity of sunlight illumination and the growth of floating phytoplankton. Increased plankton reproduction will further increase secondary breeding of aquatic - 179 - lives ranging from invertebrate to fish species. Improved water quality and assimilative capacity of He River will, to some extent, slow down water body eutrophication in this region. Animals that are adaptable to clean water will become dominating species. For example, quantity of diatom will increase over time and finally become dominating species, and blue-green algae will become less. Meanwhile, quantities of aquatic vascular plants will increase, and restoration of aquatic vascular plants has extremely important role in aquatic ecosystem. Fish species is at high tropic level in aquatic ecosystem. Restoration and multiplication of fish species rely on water quality and restoration of other aquatic biological groups at lower trophic levels. Restoration and multiplication of fish species will be achieved only when other aquatic lives are under normal growth and benign ecological cycle has been achieved. In the long run, river dredging will remove most of heavy metals and toxic substances in sediment and cut off migration and enrichment of these substances in food chain, which will increase economic value of fish. Moreover, restoration of phytoplankton and zooplankton over time will provide more attractive food and will benefit growth of chub and crucian that rely on the algae. Improved water quality, more transparent water and disappearance of odor will provide more favorable condition for growth of fish and other aquatic animal species, and will further help maintain healthy aquatic ecosystem. 5.2.1.3 Benefits of Landscaping and Ecological Environment Improvement The landscaping construction works of the Project will be implemented in accordance with the Master Urban Plan and in association with the development of flood risk control system and the urban drainage improvement system. Urban greenbelts and ecological corridor will be constructed to increase landscaping continuity, protect animal habitat, and create natural and continuous recreational space that encourages ecological-friendly hiking and cycling. Such efforts will play a critical role in protecting the urban ecosystem structure and functions and creating an urban eco-network and planning the open urban spaces. They will help increase the value of the urban landscaping system, maintain a healthy water environment, and facilitate human-water harmony. Such landscaping efforts will be helpful to maintaining the integrity of water system and full utilization of water resources. Interaction and integration of the water and mountain systems will enable the water system to become a medium connecting all blocks and create a more stable and ecologically-sustainable system of blue water and green mountains. The rehabilitated river channels will provide the local residents and tourists with a waterfront recreational area comprising of river course, revetments and urban landscaping along He River. Improved urban landscaping and ecological environment will set up a scientific link between the landscaping, cultural environment and the natural environment comprising of the surrounding mountains and water bodies to form an environment-friendly ecological landscaping system. This will also improve city attractiveness, increase land value, and create livable environment, and achieve co-development of city and urban residents. - 180 - 5.2.1.4 Benefits of Municipal Infrastructure Construction Flood control, wastewater and stormwater collection and drainage facilities provide physical assurance for normal urban operation and healthy urban development, and play an indispensable role in improving dwelling condition and urban capacity and increasing urban operation efficiency. Implementation of the Project will assure safe urban area against flood risk, improve regional water environment, construct high-standard and modernized municipal infrastructure and public service facilities to provide strong support and assurance for sustainable economic development of Hezhou city, increase urban development level, and achieve integration of reform and innovation. Meanwhile, the Project will improve institutional capacity building by providing water affair management technical assistance for Hezhou Municipal Government. Institutional capacity building will establish coordination mechanism among water affair master plan agency and water resources authorities, provide concerned training, workshop and study tour, in order to improve professional capacity of Hezhou City water resources authorities and agencies and provide powerful software support and assurance for sustainable economic development of Hezhou City. 5.2.2 Adverse Environmental Impacts and Mitigation Measures Upon the completion of the Project, adverse environmental impacts in the operation stage will mainly be generated from the Subproject of Improving Urban Drainage and Wastewater Management. Such impacts mainly include effluent, odor and noise discharged from Jiangnan WWTP in operation and noise generated stormwater pump station in operation. 5.2.2.1 Adverse Environmental Impacts associated with Jiangnan WWTP Operation and Mitigation Measures Thanks to the operation of Jiangnan WWTP, domestic sewage in this region will be collected and treated to prevent direct discharge of untreated domestic sewage into the surface water in WWTP service area and will significantly improve water environment. However, WWTP effluent will have slight impacts on receiving water body. Additionally, odor generated by wastewater aeration and sludge storage and noise from operation of pumps and air blowers will have impact on the surrounding environment, and wastewater sludge will cause environmental pollution in case of improper disposal. (i) Impact of WWTP Effluent After project implementation, uncontrolled domestic sewage will be collected in associated pipeline networks and discharged to He River after treated. Therefore, wastewater discharge impact prediction is based on scenario with WWTP operation. Jiangnan WWTP has a designed treatment capacity of 15,000 m3/day receiving domestic sewage collected in the Jiangnan East Area of Hezhou. Outfall of the WWTP is near Zhegutou along the main watercourse of He River. Considering that urban river rehabilitation and separate wastewater and stormwater collection are included in the Project, other pollution sources that discharge into the projected river sections will be ignored during the assessment of water quality impact by WWTP effluent. - 181 - Receiving water body of Jiangnan WWTP is He River. Flow velocity, river width, river depth and gradient cited for water quality prediction are all sourced from hydrological parameters of GZAR Surface Water Environment Capacity Study Report prepared by Chinese Research Academy of Environmental Sciences and Guangxi Environmental Protection Science Research Institute. The two-dimensional steady-state mixed attenuation model of bankside discharge recommended by Environmental Impact Assessment Technical Guidelines for Surface Water Environment (HJ/T2.3-93) and the S-P model recommended in HJ/T2.3-93 are used as the prediction models for the fully mixed river sections. The prediction process is shown in Annex 2. Prediction results show that an 11m long and 3m wide polluted mass will be formed around WWTP outfall under scenario of normal WWTP discharge, but the water quality of the other downstream sections will meet Class III of Surface Water Environment Quality Standard (GB3838-2002) along with the dilution and self-purification of He River. The predicted COD concentration at 2.8 km downstream of the WWTP outfall is almost same as baseline level upstream of the WWTP outfall, and predicted value of ammonia nitrogen at 11km downstream of the outfall will decrease to baseline level of influent from upstream of the outfall. Prediction results show that COD concentration at 2.8 km downstream of the WWTP outfall will decrease to baseline level. The projected COD concentration in fully mixed river sections at 3.1 km downstream of the outfall is 9.9mg/L, decreased by 10% compared with existing monitoring value of 11 mg/L. The projected ammonia nitrogen concentration in fully mixed river sections is 0.314 mg/L, slightly higher than existing monitoring value of 0.313 mg/L but decreases afterwards to baseline level at 11km downstream of the WWTP outfall. (ii) Impact of WWTP Odor and Mitigation Measures WWTP will inevitably generate odor during operation. Odor generation concentrates in bar screen, wastewater pump chamber, grit removing tank, A 2/O reaction tank, sludge concentration tank, and dewatering facility. Odor is caused by generation of H2S, ammonia, volatile phenol, methane, and methanol in the process of biological anaerobic and aerobic fermentation. Based on information collected of municipal WWTP odor analysis, uncontrolled H2S and NH3 emission has relatively higher concentration and will pollute ambient air within and outside the WWTP. As presented in Typical Case Studies for Environmental Impact Assessment, monitored odor concentration of a WWTP with a design capacity of 40,000 m3/day was 11.0, 4.4 and 1.1 at 100 m, 200 m, and 400 m downstream of the WWTP, respectively, under meteorological condition of breeze and air temperature of 22 degree centigrade. All these monitoring values could meet Pollutant Discharge Standards for Municipal Wastewater Treatment Plants (GB18918-2002) Class 2 waste gas emission limit (odor concentration limit 20) within 100 m and farther. Finalized health protection distance of Hezhou municipal WWTP (capacity expanded to 30,000 m3/day) also located in Hezhou City is 100 m, therefore this distance is also applied to Jiangnan WWTP. Based on field investigation, the nearest environmental - 182 - sensitive receptor is located more than 100m away from the plant boundary and WWTP odor will have very insignificant impact on environmental sensitive receptors. Odor capture and treatment measures can be taken for major odor-generating structures to make sure odor level could meet applicable standard at WWTP boundary. Major structures that have odor generation include inflow pump chamber, aeration tank, sludge concentration tank, and sludge dewatering chamber. Currently biological odor removing methods are adopted in most cases. Biological odor removal depends on micro-organic metabolism to degrade odor substances and is suitable for removal of WWTP odor. Biological filter is the most mature technology and is odor removing method widely applied. Under suitable condition, solid carrier (stuffing) attached by large quantity of micro-organics absorbs odor pollutants and decomposes odor pollutants to carbon dioxide and water. Bio-filter has advantages of low operation cost, high removing efficiency, and easy operation without secondary pollution, and is widely applied. (iii) Impact of WWTP Noise and Mitigation Measures Noise sources of WWTP include air compressor, air blower and pumps concentrating in inflow pump chamber, sludge dewatering structure, sludge circulating pump and air blower chamber. Noise intensity is shown in Table 5-10. Table 5-10 Impact of Major WWTP Equipment Noise Noise Source Intensity dB (A) Equipment With Mitigation With Mitigation Measures Measures Wastewater Pump 90-100 80 Sludge Pump 90-100 80 Air Compressor 95-105 85 Air Blower 80-90 80 Transportation 75-80 -- Vehicle It can be seen from Table 5-10, noise intensity can be as high as 105 dB (A) without mitigation measures being taken. When noise damper is installed and the building is enclosed, noise intensity will decrease by around 20 dB (A). Major noise-generating equipment of WWTP includes water pump, air compressor and air blower. Noise level in air blower room ranges from 80 to 90 dB (A), and will decrease to 80 dB (A) when noise reduction measures are taken. Usually pumps are installed within buildings, in which noise level is 90 to 100 dB (A) and will decrease to 80 dB (A) after mitigation measures are taken. Further reduced by ambient air and distance, noise at WWTP boundary can meet Ambient Noise Emission Standard on the Boundary of Industrial Enterprises (GB12348-2008) Category 2, allowable maximum noise level 60 dB (A) for daytime and 50 dB (A) during night. Noise mitigation measures include: - 183 - (1) Selection of advanced low-noise equipment and submerged wastewater and sludge pumps, and installation of air blower indoors. (2) Firm pump foundation that can damp various vibrations and provide solid support; (3) Proper maintenance of water pump, regular inspection of concentricity of motor and pump axle, and good lubrication of bearings to reduce abrasion of pump components and parts; (4) Installation of acoustical material and vibration damping devices along internal wall of pump chamber, roof, floor and next to equipment to effectively control and eliminate noise transmission and reflection, such as asbestos board and vibration damper; and (5) A greenbelt around the pump house should be constructed through inter-planting trees and bushes to improve landscaping and reduce waste gas, noise and odor impacts on surrounding environment. Tree species with strong pollution resistance should be selected. (iv) Impact of Solid Waste during WWTP Operation and Disposal method A2/O micro-aeration oxidation ditch process is proposed for Jiangnan WWTP. Solid wastes generated include residual sludge and screening solid waste. Using Hezhou municipal WWTP expansion that adopts A2/O process as reference, it is anticipated Jiangnan WWTP will generate residual sludge of 3 tons each day or 1,095 tons per year, and generate screenings of 0.1 tons each day or 36.5 tons per year. Sludge cake will be hauled to Hezhou sludge treatment facility for safe disposal. Hezhou sludge treatment facility is located in Xinyan Village Jiuniu Community of Hezhou City Liantang Town (planned landfilling area of Hezhou municipal solid waste landfill zone 2), with designed treatment volume of 100 ton/day sludge with water content of 80%. This facility is composed of sludge receiving system, sludge treatment system, odor treatment system and wastewater treatment system. Conditioning by dilution plus deep dewatering process is adopted to dewater the sludge received with water content of 80% to dry sludge cake with moisture content 60%, and then the sludge cake is disposed of in landfill together with domestic solid waste. Sludge generated in Jiangnan WWTP is domestic sewage sludge with high water content of 80% or more, and sludge quantity will be approximately 3 tons a day. Currently construction of Hezhou sludge treatment facility has commenced and construction will be finished before operation of Jiangnan WWTP. Hezhou sludge treatment facility has adequate capacity to accommodate sludge from Jiangnan WWTP. Therefore, disposal of Jiangnan WWTP sludge in Hezhou sludge treatment facility is feasible. (v) Health Impact and Protective Measures - 184 - Jiangnan WWTP has a staff of around 30. Wastewater and sludge contain various pathogenic bacteria and parasitic ovum, and vapor over wastewater treatment facility could spread bacteria and virus. Exposed to micro organics in wastewater and sludge, operation staff of WWTP may be infected and catch disease. Infection may be caused by direct inhalation or indirectly by water drops sticking to skin and clothes, which occur in aeration tank, effluent weir, irrigation spraying outlet, air blower room, and dewatering room. In area with much moisture condensation, chiffon-type respirator will help reduce inhalation of toxic substances. Usually this kind of direct pathogen infection is confined to operators of the WWTP, with very low probability of occurrence in other people. However, if infection of the operators cannot be effectively controlled, disease may be spread to people outside the WWTP. Therefore, the following measures should be taken to ensure health of WWTP staff. (1) Proper protective clothes, gloves and respiration mask should be provided for WWTP workers. Anti-skid shoes should be provided for transportation workers and steel-toe shoes should be provided for all the workers to prevent foot injury. Workers working near high-noise equipment should be provided with noise protective devices. Workers operating near heavy movable equipment, bucket, crane and transportation vehicle dumping site should be equipped with safety helmet. Guardrails should be installed around all the process containers and water tanks. Lifeline and personal floating device should be available for use when operators are working within the guardrails, to make sure life saving devices being in place in emergencies. (2) Dangerous contact should be reduced through design and development of technical and material specifications (e.g. ventilation, air conditioning, enclosed conveyor belt, low-load and different heights, anti-skid floor, safety guardrails for stairways and aisles, spill protection and leakage prevention, noise control, dust prevention measures, gas alarm system, fire alarm and control system, and evacuation devices). (3) Bathroom and dressing area should be provided for the operators for after-work bath and dressing, and work clothing laundry service should be provided. Additionally, frequent hand washing of WWTP staff should be encouraged. (4) Enclosed space access plan conforming to the national requirements and internationally recognized standards should be developed for construction activities in enclosed treatment zone. Ventilation is mandatory before entering. Operators should be equipped with gas detector and valve connected with process container should be locked to prevent accidental overflow during maintenance. (5) Eating, smoking and water drinking should be banned outside the designated area. (6) Operators should be separated from bacteria spreading channels via mechanical overturning (e.g. use of tractor or front-end loader with enclosed air - 185 - conditioning or heating driver cab). Ventilation system should be provided in case of manual overturning. (7) Provision and use of proper personal protection clothes and devices should be required to prevent wastewater contact, such as rubber gloves, apron and boots. Medical care should be provided in a timely manner to prevent infection, for example binding up of skin injury like cut and scrape wound. Protective clothes and glasses should be used to prevent spill contact. (8) Instruction to use of safety devices and personal health practice should be included in safety training program for the operators to reduce exposure to pathogen and bacteria carrier. (9) Vaccination for preventing B type hepatitis and tetanus and health monitoring should be provided for the operators, including regular health check. Persons having asthma, diabetes or weak immune function are not suitable for working in WWTP. 5.2.2.2 Impact of Stormwater Pump Station Noise and Protective Measures Stormwater lift stations are designed for Shizigang Drainage Canal and Huang’ansi Drainage Canal. The pump stations are suspended under normal condition and are only put into operation to prevent backward flowing of river water. Major impact during operation is noise. Noise sensitive receptors are residential buildings in Xiyue Street and Mid Jiangbei Road. Short term and intermittent operation of these pump stations will have insignificant impact on environmental sensitive receptors after noise reduction by foundation and proper equipment maintenance measures are taken. Noise reduction measures to be taken are listed as below. (1) Selection of equipment with good operation performance and low noise, and vibration damping measures are taken during equipment installation to reduce noise; (2) Firm pump foundation that can damp various vibrations and provide solid support; (3) Proper maintenance of water pump, regular inspection of concentricity of motor and pump axle, and good lubrication of bearings to reduce abrasion of pump components and parts; and (4) Installation of acoustical material and vibration damping devices along internal wall of pump chamber, roof, floor and next to equipment to effectively control and eliminate noise transmission and reflection, such as asbestos board and vibration damper. 5.2.2.3 Analysis and protection measures for the operaitonal impacts of the monitoring station laboratory Equipment and test reagent must be purchased as a part of the monitoring station construction to increase the monitoring capacity. A certain volume of wastewater and a small volume of exhaust gas and waste test reagents will be generated in the - 186 - operation of the laboratory. Wastewater generated in the laboratory is mainly wastewater from washing of instruments. Although such wastewater contains little pollutants, there are relatively many types and compositions of the pollutants, including the most common organics, heavy metal ions and hazardous microorganisms as well as the less commonly seen baceria, toxins, pesticide residues, test reagent residues, etc. The wastewater containing strong acid, strong alkaline or toxic substances will generate serious enviornmental pollution if directly discharged into the natural environment. Therefore, such wastewater must be treated before discharged into the municipal pipelines. In the process of test, a small amount of exhaust gas will be generated, mainly organic exhaust gas that is ventilated outside the laboratory via the ventilation cupboard and will generate little environmental impacts. The waste drugs and test reagents are hazardous wastes and must be recovered for disposal by a qualified unit. Therefore, the wastewater, exhaust gas and solid wastes in a laboratory require reaosnable disposal, thus raising the requirements of management for the laboratory. 1. The wastewater, exhaust gas and solid wastes in the laboratories must be properly treated according to the national laws and regulations on environmental protection and random dumping, storage and discharge are prohibited. 2. Acid and alkaline waste liquid generated in the process of test and analysis and waste liquid containing highly toxic drugs must be dumped into the waste liquid cylinders for the right classification and delivered to the waste liquid storage room for centralized treatment by a qualified unit. 3. Digestion of specimens must be conducted in a ventilated cupboard and all the exhaust gas generated must be discharged at high altitude via the air duct. 4. Wastes generated in the process of testing and analysis shall be handled in such a way that intoxic wastes are dumped into the garbage bins, contaminating wastes are collected and delivered to the waste storage room for centralized treatment by a qualified unit. 5. Proper preventive measures should be taken against fire, burglary and poisoning hazards and risks. Fire protection devices and necessary poison prevention facilities should be provided in the laboratory. 6. Flammables, explosives and toxic substances must be properly stored, claimed and registered according to the respective stipulations. - 187 - 7. Smoking, laundry, cooking and storage of personal food in the refrigerators are prohibited in the laboratory. Loud noises and frolic are banned during test operation. 8. The codes of operation should be strictly followed. - 188 - 6. Environmental risk analysis and mitigation measures 6.1 Identification of environmental risks The potential environmental risks in World Bank Loan Guangxi Hezhou Urban Water Infrastructure and Environment Improvement Project will arise from the proposed Jiangnan WWTP as a part of the Urban Drainage and Wastewater Management Improvement Subproject considering the engineering features of the Project. The main environmental risks include: (1) massive direct discharge of untreated sewage may occur in case of any events of emergency, such as power outages, natural disasters and equipment failure ; (2) Environmental risks may arise from leakage of sewage into storm water pipe and discharge of untreated sewage into surface water caused by broken sewage pipes; (3) Personal safety risks may arise from the accumulation of harmful gas in the course of sewage pipeline maintenance. 6.2 Analysis of potential impacts from WWTP accidents with environmental risks 6.2.1 Emergency accidents Improper equipment maintenance or quality problem may cause failure of equipment and facilities and reduction of treatment efficiency, or even cause direct discharge of untreated sewage. Some irresistible external causes, such as power outage, natural disaster might result in equipment failure and direct discharge of untreated sewage. This is the worst case of abnormal operation. The sewage will be discharged into surface water through bypass if power outage causes facility failure. 6.2.1.1 Water quality prediction model The effluent of Jiangnan WWTP will be discharged into He River. Considering the size of He River, the impact of discharged of untreated sewage is projected using the two-dimensional steady-state attenuation model recommended in the Technical Guideline of Environmental Impact Assessment-Surface Water (HJ/T2.3-93). The S-P mode was adopted for the full mixture section. The impact of discharge of untreated sewage (i.e. at the designed influent concentration of the WWTP) was also predicted in the scenario of accidental discharge. The details of the prediction process is described in Annex 2. According to the prediction results, COD of the 10 m wide and 220 m long river section downstream of the outlet exceeds the discharge standard by a maximum factor of 6.46. NH3-N of the 10m wide and 500 m long section downstream of the outlet exceeds the standard by a maximum factor of 15.10. It can thus be seen that the water quality of He River will be affected to a certain extent or even exceeds the standard at some river sections in the case of accidental discharge. Therefore, it is - 189 - necessary to strengthen WWTP operation and management to prevent accidental discharge. 6.2.2 Risks of sewage pipeline leakage In case of any leakage of sewage pipelines, collection of sewage will become unlikely. Untreated sewage will cause pollution to surface water environment. Sewage leaked from pipelines and permeated into the ground may result in pollution of not only the soil and environment in the surrounding areas and also negative impacts on ground water quality. Based on the status of operation of the existing stormwater and sewage pipelines, the probability of pipeline leakage is not high unless in the case of uncivilized construction and human damages. 6.2.3 Staff health risks from failures of WWTP system As the WWTP system failure is always unexpected, it will cause significant damage to the working staff and endanger their life. When environmental accident occurs, the first thing affected is the health and safety of the staff in the wastewater treatment plant. 6.2.3.1 Analysis on poisoning risks and impacts caused by toxic gases When an accident occurs in a particular structure of the sewage treatment system, maintenance workers need to enter the enclosed space, such as sewer, water collection well and wastewater tank, to repair the system immediately. In such places, high-concentration toxic gases, such as hydrogen sulfide, methane, carbon dioxide, etc. are likely to occur and accumulate. If no protective measures are taken during maintenance, the workers might inhale the toxic gases due to poor ventilation, which might result in dizziness, poor breath and other symptoms or even casualty. According to relevant data, there have been dozens of accidents with threats personal safety in more than 20 cities caused by exposure to toxic gases in the sewers and combined pipelines or fire explosions resulted from flammable methane in the pipelines. Therefore, it is essential for the WWTP operators to take occupational safety measures to prevent damages from toxic gases. The most effective way to prevent poisoning is to take ventilation measures to disperse the poisonous and harmful gases completely and make the working space full of fresh air. If adequate ventilation is not possible, the dangerous space should be avoided and effective protective equipment must be worn during operation. Protective equipment includes gas marks, air supply masks and so on. Testing devices needed include test paper and gas detector, etc. 6.2.3.2 Analysis on health risks and impacts caused by pathogens The wastewater and sludge contain a variety of pathogens and parasite eggs. The fog and water on the treatment facilities can spread bacteria and viruses. The WWTP workers exposed to the micro-organisms in the sewage and sludge have the risk of infection through direct inhalation of gas or caused by droplets on the skin or clothing. This kind of gas can be found at aeration tank, effluent weir, irrigation outlet, blower room, dewatering workshop and other places. In places where water vapor is highly - 190 - condensed, the gauze-type respirator can reduce the inhalation of toxic substances. This type of environmental risk mainly results diseases caused by direct infection of pathogen. People outside of the plant is unlikely to be infected, but their heath will be also endangered by spread of disease due to poor control of the condition of infected workers.. 6.3 Risk mitigation measures 6.3.1 Equipment safety assurance measures The failure of pump, valve, electrical apparatus and other instrument used in the treatment facilities and system will reduce the treatment efficiency or even cause outage of the whole WWTP. This is a kind of potential risk. The emergency response actions in this regard include: (1) A redundancy equivalent to 0.5 times of the maximum capacity is considered in the process design for the WWTP system so as to have a buffer in the event of accidents; Compatible processing equipment (reflux pump, reflow pipes, valves and meters) should be provided so that the system buffer and backflow equipment can be started to retreat the unacceptable effluent to the specified discharge standard in case of equipment failure affecting the normal operation of the system. (2) For the vulnerable equipment, multiple standby equipment and adequate spare parts should be assured on site. All key mechanical and electrical equipment should be configured in such a way that one standby is available. (3) Use high-quality equipment. All machinery, electrical appliances, instruments and other equipment selected should have good quality, low failure rate, good durability and be easy to maintain and repair. (4) During operation, the operators shall strictly follow the rules and regulations of facility operation and conduct regular inspection and timely maintenance to reduce equipment failure rate. (5) The electrical equipment should be operated in compliance with the grounding protection regulation and be equipped with automatic tripping circuit. The main equipment shall be operated under the surveillance of a computer data monitoring system and be capable of giving alarms and recording the location, time and features of accident so that the workers can organize maintenance promptly. All electrical equipment shall be installed with a protection system according to the relevant safety requirements. (6) Dual-circuit power supply shall be used to assure normal operation of the power supply facilities and lines. 6.3.2 Protection measures for abnormal wastewater discharge 1. Emergency responses to unstable water amount caused by various factors shall be fully considered in the design to alleviate the unfavorable situations. 2. Technical management measures during WWTP operation include: - 191 - （1） Establishing a WWTP operation and management responsibility system; （2） Organizing trainings for the management and technical staff and establishing technical appraisal records so that those failing the technical appraisal are not allowed to be on duty; （3） Employing experienced professional and technical staff to be responsible for the technical management in the WWTP; （4） Organizing domestic and abroad trainings for the technical staff; （5） Strengthening inspection of pipelines and detecting and resolving problems in a timely manner; （6） Strengthening maintenance and management of equipment and facilities. Key equipment shall have standby and dual power supply. 6.3.3 Emergency responses to unexpected wastewater discharge accident The following measures shall be taken in the event of unexpected wastewater discharge accident in a WWTP: (1) Ensuring the normal operation of grid and grit chamber so that the SS and COD in the influent can be reduced to certain extent; (2) In the event of irresistible external causes, such as blackout of dual power supply and natural disaster that will lead to discharge of untreated wastewater, the wastewater shall be stored in the emergency tank and treated once the wastewater treatment system is repaired to ensure the safety of the water body; (3) In the event of and during the handling of an accident, warning signs shall be erected in the waters near the outfall to remind all parties concerned to take precautionary measures. 6.3.4 Prevention and control measures for risks of pipeline leakage （1） The local conditions shall be considered to select proper pipe material and ensure pipeline quality and service life. The drainage foundation shall meet the mechanical design requirements and be constructed in strict accordance with the detailed design of width, thickness and strengths of foundation to assure good construction quality. （2） Careful inspection shall be conducted before pipeline installation. All pipe materials shall be carefully checked to avoid any cracks and leakage. On the other hand, it is necessary to check the center line and the edge of the foundation with the drawings and ensure the size and strength of all bed course satisfy the requirement. It is also necessary to check whether the manhole location, spacing and concrete strength and the preparation of anti-seepage mortar can comply with the national standard. （3） During pipeline installation, the cement mortar shall be prepared according to the stipulated mix design. Protruded seams often occur at the pipeline connections due to squeezing during installation. If not handled in a timely - 192 - manner, the water flow profile and velocity may be affected and debris accumulation and pipeline congestion may occur. （4） The pipe base concrete and plaster mortar must reach the required strength before trench backfill. Action should be taken to avoid gravel impacts on the pipelines. Large crushed stone and hard objects should not be contained in the gravel and aggregates. Backfill and compaction should be conducted simultaneously on both sides of the pipeline and lay-by-layer on top of the pipeline so as to form an integral load-carrying mass to spread the unloading force at the pipe crest to protect the pipelines. （5） The construction unit shall establish a complete system of pipeline monitoring and management during operation, and clear the pipe network and replace the damaged pipes in time to avoid water pollution caused by pipeline leakage. 6.3.5 Personal safety protection measures （1） The operation and management staff shall receive safety education before formal operation. The plant shall establish a set of safety operation procedures and management system. These procedures shall be strictly enforced and the performance shall be inspected during operation. （2） The requirements of water supply and drainage, heating and ventilation, lighting and health shall be considered in the design. Air conditioning facilities shall be provided in the places involving lengthy operation. The enclosed structure or work place with poor ventilation shall have mechanical ventilation facilities. （3） Life jacket, life buoy, safety belt and safety helmets and other personal protective supplies shall be provided on site. The workers who have to enter the pipeline for inspection or operation shall wear the necessary protective devices, such as safety suits, gas masks, air masks, gas detection equipment, test strips, etc., to prevent poisoning and at least two persons present. （4） The walkway of tanks shall have handrails and lighting facilities to ensure pedestrian’s safety. （5） All electrical equipment shall have protection system that meet the relevant safety requirements and grounding protection shall be properly executed for high-voltage equipment. （6） The hazardous parts of machinery and equipment, such as belt, gear and wheel shall be installed with protective device. （7） It is necessary to strengthen safety management and establish a responsibility system. All dangerous areas shall have warning signs at visible positions. Platforms with a height of more than 1.2 m shall have fences. Ventilation shall be provided in the places where toxic and harmful gas might gather. The operation and maintenance unit shall set up a safety and labor protection department to be responsible for safety protection and labor protection. （8） Sanitation room (toilets, lavatories, dressing rooms, etc.) shall be provided for the sake of actual needs and convenience. In addition to providing ventilation in the places with poor working condition and shading for the outdoor work, - 193 - lounge shall also be provided. There shall be centralized bathrooms in the plant. （9） The staff directly exposed to sludge, wastewater or domestic solid waste shall take physical examination and be vaccinated on a regular basis (such as hepatitis A, hepatitis B, etc.). 6.4 WWTP emergency response unit and its roles and responsibilities The emergency response unit of a WWTP mainly comprises of the leading group office and the emergency response teams of different disciplines, including rescue team, liaison team, logistics team and fleet team.

Cumulative impact assessment Hezhou Municipality was built along the He River. The urban center is on the north bank of He River. However, the terrain of the urban center is flat and depressed and the water conservancy infrastructure constructed in the past against the standard for a county town no longer match with the requirement of development of a municipal-level city. Hezhou Municipality has development a future strategy for development of the main axis along the He River, where the urban center is the most important node. In order to achieve the goal of urban development, the relevant government departments have begun to plan and construct flood control and drainage projects in recent years. On the other hand, if Hezhou’s water pollution control cannot keep up with the pace of urban development, the pollution of urban inland canals in Babu old city area and tributaries of He River will become more serious and even expand to northwest and south of He River. In order to alleviate water pollution, Hezhou will make vigorous efforts in promoting the construction of drainage works, including wastewater treatment plants and the associated sewage and storm water pipelines. The relevant government departments are also planning to promote wastewater treatment in villages and towns in the territory. Due to possible superimposition of impacts from projects already constructed, under construction or to be constructed along the main watercourse and tributaries of He River, such as flood control and drainage works, wastewater treatment plant and other infrastructures, and the impacts of the Project, cumulative impacts may arise on the valued environmental and social component (VEC) in the watershed. In such a context, with reference to IFC’s Cumulative Impact Assessment and Management: Guidance for the Private Sector in Emerging Markets and through consultation with the stakeholders, the key VECs were identified and screened to determine the scope, indicators and thresholds of cumulative impact assessment. The cumulative impacts on the identified VECs were assessed. In addition, the Project and its linked projects will bring significant social benefits and certain negative impact. Therefore, the cumulative social impacts were also assessed. A series of safeguard measures were put forward on the basis of consultation with relevant departments. 7.1 Scope of cumulative impact assessment 7.1.1 Affected VEC As discussed in Section 5.2, the long-term impacts of the Project will be mainly reflected in the reduction of water pollutants and improvement of flood control and drainage management. Upon full completion of the Project, significant positive impacts will be produced on the urban water environment in Hezhou from improvement of water quality in the tributaries of He River thanks to the construction of the sewage interception and dredging works. The proposed Jiangnan WWTP will - 195 - greatly reduce pollutant load into He River. This Project will greatly reduce the flooded area and economic loss and assure urban flood safety through improvement of flood control standard and rehabilitation of the main watercourse of He River. There will be remarkable benefits from flood control. Based on desktop review and consultation with relevant departments, the activities likely to produce cumulative impacts with the long-term impacts of the Project are identified, including the existing and proposed flood control works (dikes, pumping stations, etc.) along the main watercourse of He River, river-lake connection works and water environment remediation works (urban and rural wastewater treatment facilities). The potential affected VEC, including flood control and drainage benefits, reduction of river pollutants, hydrological conditions and aquatic ecosystem, were screened at the early stage of cumulative impact assessment. As discussed in section 5.2.1, the Project will not change the velocity, and flow of dry season and normal season and other hydrological condition of main watercourse of He River. In the event of a flood of the design level, the peak flow and velocity in the main watercourse will increase and the water will flood over the bank. During the flood period, He River erosion will be more serious. However, with various measures taken, the changes of sediment volume will be insignificant. According to the analysis, the impacts caused by the proposed dikes and drainage pump station on the main watercourse of He River will be basically similar with the Project. There will be no influence on the velocity and flow of normal season and dry season as the main watercourse will not be widened; the impact on sediment volume is negligible; the peak flow and velocity will increase during the flood period but at the same time, the floodplain area and the economic loss can be reduced. The main function of the proposed river-lake connection is to regulate peak flow in the flood period. All of these works will bring positive flood control benefits. Therefore, the cumulative impact assessment focuses on the impact in the flood period. The hydrological situation will not be significantly affected, thus not considered as important VEC, while the benefits of flood control and drainage are identified as key VECs to be assessed. According to survey and consultation with experts, the aquatic organisms in He River are common species. There are no fish spawning grounds, feeding grounds or overwintering grounds in He River. After decades of development, there are cascade hydropower stations before He River flows into Xijiang River. There are no rare aquatic organisms or migratory fish species, or important natural habitat. Most of the fishes are economic species. As discussed in section 5.1.5, the Project has little impact on aquatic organism. The linked projects identified in the cumulative impact assessment are similar to the Project: the construction activities of dike and pump station may cause minimal disturbance to the surface water body, but the impact on aquatic organisms is temporary, minimal and reversible. Such disturbance will disappear as the construction is completed. The Project and the other linked projects will not cause long term cumulative impact on aquatic ecosystem. Therefore, it is not determined as a key VEC under this assessment. - 196 - In summary, it is finally determined that the benefits of flood control and drainage and reduction of water pollutants are determined as the key VECs under the cumulative impact assessment. 7.1.2 Temporal and spatial scope of assessment In the course of the cumulative impact assessment, the relevant activities are screened from the four plans, i.e. Hezhou Urban Flood Control Plan, Hezhou Municipality Master Urban Plan (2016-2030) (Draft), Implementation Plan for Integrated River Rehabilitation of Urban Section of He River (2017-2020), and Hezhou Urban Ecological River System Planning (2014-2030), based on the results of consultation with Hezhou Municipal Planning Bureau, Hezhou Municipal Water Resources Bureau, Hezhou Municipal Engineering Administration Bureau, Hezhou Municipal Housing and Urban-Rural Development Bureau and Hezhou Municipal Environmental Protection Bureau. The scope of this assessment was determined on the basis of comparison with the scopes specified in each of the aforesaid plans.

As shown in the table above, the section of the main watercourse of He River to be influenced by the related planning is the section from the upstream Huangshi Hydropower Station to the downstream Hejie WWTP. The Jiangnan WWTP proposed in the Project is at the downstream. The water quality at 11 m downstream of its outfall can meet with the - 198 - water environment quality standard. The effluents of Jiangnan WWTP and the Mawei River joining He River at 200 m downstream will have certain cumulative impacts. The cumulative impact of Hejie WWTP at 8 km downstream is minimal. In order to narrow the scope of assessment, the boundary of cumulative impact was set at the Duling Hydrological Station located 4.5 km downstream of the junction of Mawei River and He River. In such a context, the scope of cumulative impact assessment of the main watercourse of He River starts at the upstream Huangshi Hydropower Station and ends at the downstream Duling Hydrological Station with total length of 30 km. On the other hand, the proposed river rehabilitation works of the northern tributaries of He River and river-lake connection works will cause cumulative impact to the Project. Therefore, the northern part of the urban center is also included into the identified scope of assessment. To sum up, the spatial scope of assessment covers the main watercourse of He River (Huangshi Hydropower Station to Duling Hydrological Station) and north part of Hezhou urban center (see Figure 7-1). The baseline year of the cumulative impact assessment is 2017; according to the schedule of the Project and timeframe of relevant planning activities, the temporal scope of the predictions and analysis will be 2018-2023 for the short term and 2030 for the long term. - 199 - Figure 7-1: Schematic Diagram of the Scope of Cumulative Impact Analysis - 200 - 7.1.3 Related development activities As mentioned above, He River flows from northwest to southeast through Hezhou Municipality. He River will be the main axis of Hezhou Municipality in the future, with the urban center of Hezhou as the most important node. In order to achieve the goal of Hezhou urban development, the relevant departments are revising "Hezhou Municipality Master Urban Plan (2016-2030) (draft)". However, the flood control facilities of Hezhou Municipality are yet to be improved and the City is affected by floods almost every year. The existing flood control facilities in Hezhou Municipality cannot meet the needs of urban development. To this end, the relevant departments have developed the Urban Flood Control Plan of Hezhou, Guangxi, which integrated flood prevention and control measures to enhance the urban flood control capacity. On the other hand, the combined storm water and sewage system are still common in Hezhou urban area. The tributaries and drainage canals along He River receive large volume of sewage and He River is thus polluted. In order to achieve maximum collection rate of urban sewage, improve the urban drainage network, and address the problems of flooding and water pollution, the relevant departments developed a specific implementation plan in 2017, planning to implemented comprehensive river rehabilitation in 2-3 years in the urban river sections. The Hezhou Municipality Master Urban Plan (2016-2030) (draft) also develops an outlook for the urban sewage treatment facilities in the long term. Under the guidance of the Master Urban Plan, Hezhou Municipality proposed to connect as many natural rivers and lakes as possible in the future and speed up the construction of a modernized regional ecological water system relying on the projects of regulation and connection of natural rivers and lakes, medium-sized reservoirs. The Hezhou Municipality Urban Ecological Water System Planning (2014-2030) has been developed to constantly optimize configuration of water resources and further improve water resources and water environment capacity of Hezhou Municipality. The linked projects already constructed, under construction and proposed to be constructed were identified on the basis of Hezhou Urban Flood Control Plan, Hezhou Municipality Master Urban Plan (2016-2030) (Draft), Implementation Plan for Integrated River Rehabilitation of Urban Section of He River (2017-2020) and Hezhou Municipality Ecological Water System Planning (2014-2030). The identification matrix is given in Table 7-2. The related development activities are shown in Figure 7-2. Based on the temporal scope of the cumulative impact assessment, statistics of the expected progress of the Project and the related activities for the short-term scenario of 2018-2023 and the long-term scenario of 2023-2030 are summarized in Table 7-3 for further analysis and assessment. - 201 - Table 7-2 Identification Matrix of Related Development Activities Related Development Activities Identified Impacts Flood Reduced SN Development Completion Drainage Details Control Inflowing Activities Date Benefits Benefits Pollutants Existing Hezhou WWTP Current capacity: 30,000 m3/d; the wastewater is treated to Completed Positive Class 1A of Pollutant Discharge Standards for Municipal impact 1． Wastewater Treatment Plants (GB18918-2002) before discharged into He River through 1000 m long dedicated pipeline.

The overall condition of the He River Watershed is that floods are frequent and the water environment is poor. 7.2.1 Status quo of flood control and drainage The flood control system of the main watercourse of He River is not completely enclosed. Due to slow construction progress of flood control infrastructure, He River does not have a sound flood control engineering system. The hydropower stations constructed along He River lack effective regulation and management. The existing flood control infrastructures are mainly flood dikes. Except the dikes constructed in a few sections in the urban center of Hezhou against the standard for floods with a recurrence period of 20 years (with a length of about 2.8 km), no dikes or revetments are constructed in the other river sections. There is no flood control facility in Pinggui district and the fold control capacity is weak. There are two existing large reservoirs, namely Guishi Reservoir and Hemianshi Reservoir. However, the flood control function of Guishi Reservoir has not been determined. Constructed a long time ago, the other hydropower stations along He River were are aged and commissioned or transferred to other administration authorities. Therefore, flood regulation is of significant difficulty and the flood control capacity is affected. The current drainage capacity in the watershed is very low. The flood drainage system was constructed a long time ago. Most channels were damaged seriously. Many villages and towns still don’t have any flood drainage facility. Hezhou urban area is located in the karsts basin. The terrain is flat and shallow. Flash flood flows into the city during flood season and, under the effect of backwater, flood drainage becomes difficult. Most of the drainage system in old urban area are rain and sewage combined drainage system. Due to the absence of a separate drainage system, a part of the municipal domestic and industrial wastewater is discharged into Huangansi Drainage Channel, Shizigang Drainage Channel and He River together with storm water through the pipelines under the roads. Poor drainage capacity leads to waterlogging of sewage and stormwater during rainstorms. Currently, the storm water in the current scope of design is discharged into the surrounding environment freely or via the trenches. The size of the pipeline trench is normally 300×300 or d300 pipe. As the pipe is too narrow, blockage and sedimentation is serious. The urban area of Hezhou Municipality within the scope of assessment is the flood-prone area in the He River Watershed. Since 1990, there have been significant floods in the He River Watershed, such as the floods happened in July 1994, June 1998, July 2002, and June 2005. The flood occurred in July 2002 alone resulted in the flooding 127,800 mu cultivated land and - 214 - affected crops in a total area of 964,000 mu and a total population of 1.1615 million. This flood caused a direct economic loss of CNY 2.043 billion. With the poor flood protection system of He River, Guishi Reservoir, a reservoir in the watershed with an active capacity of 155 million cubic meters, has a certain buffer function to the urban area 59 km away down the stream, but its flood prevention function remains undefined. With a low flood control level, the current revetments cannot play their roles of flood control. Substantially in a state of zero protection against floods, some townships have no effective measures to resist floods from the external river. The dike construction works in Hezhou urban area have just started and the flood protection system is not yet enclosed and far from enough to meet the requirements of urban flood control. Besides, there are many structures across He River in the urban area and these structures will involve certain impact on flood passage capacity of He River channel. 7.2.2 Current status of water environment According to the historical monitoring data1, the fecal coliform of some locations at Pinggui section exceeded the standard. All of other parameters meet the Class III standards specified in the Surface Water Quality Standard (GB3838-2002). The non-compliance of fecal coliform is mainly caused by the domestic wastewater discharged along He River. All monitored indicators downstream of He River urban section have satisfied the requirement of Class III of Surface Water Quality Standard (GB 3838-2002)2. The monitoring results as shown in Section 4 indicate that the water quality of the main watercourse of He River satisfies the standard. In general, the current water quality of the main watercourse of He River is fine, but still threatened by the direct discharge of sewage along He River. As analyzed in section 4.4, the current water quality of Lining River, Changlong River, Huangtian Branch Channel and Shizigang Drainage Channel is worse than Class V, thus no satisfying Class IV standard specified in the Surface Water Quality Standard (GB 3838-2002). In addition to the function of flood discharge, these urban inland canals and branch channels are also receptors of industrial and municipal wastewater along He River. Such wastewater is far beyond self-purification capacity of these rivers, resulting in deterioration of water quality of the urban inland canals. The key non-compliance indicators are typical pollutant of municipal wastewater, such as ammonia nitrogen, total nitrogen, total phosphorus and fecal coliform. The pollution of these urban inland canals and channels is mainly caused by municipal wastewater along He Rivers. Incorporation of the polluted water will threat the water quality of the main watercourse of He River. 1 Referring to the EIA Report of Hezhou Pinggui WWTP and the Supporting Pipeline Project (monitoring data developed in June 2012). 2 Referring to the EIA Report of Hezhou WWTP Expansion Project (monitoring data developed in December 2014, July and August in 2015) - 215 - 7.3 VEC Cumulative impact analysis 7.3.1 VEC assessment indicator system The VEC assessment indicator system and assessment standard or limits for this assessment are defined with reference to the flood protection and drainage objectives determined in the top planning for the He River Watershed as well as the relevant standards.

A part of the dike construction works under the Project is also included in the Master Planning of Urban Flood Control of Hezhou Municipality. Superimposition of the benefits of the Project and the other flood control works listed in Table 7-2 will lead to significant improvement of the flood control capacity of He River Watershed. See Table 7-5 for further details. Table 7-5: Analysis of Flood Control Benefits Item Short-term benefits (2023) Long-term benefits (2030) The flood protection level of mainstream and tributaries of He River are Outcomes of the respectively P=2% and P=5%; the design standards of the main watercourse Project dike and cofferdam are Level 2 and Level 5 respectively while that for the tributaries is Level 4. With 61% of the dike construction With the entire dike construction completed for the main watercourse completed for the main watercourse of He River, the flood control standard of He River, the flood control standard for the completed section will reach for the whole He River will reach P=2% after regulation.

Superimposition of the benefits of the Project and the drainage works listed in Table 7-2 will greatly improve the drainage capacity of Hezhou Municipality and the drainage capacity of the flood drainage zones in Hezhou Municipality will be significantly increased and the cumulative drainage benefits will be significant. See Table 7-6 for detail.

By 2023, the drainage capacity of By 2030, the drainage capacity of Pinggui District, the urban center of Pinggui district, Hezhou urban Hezhou Municipality and Hejie Town center and Hejie town will meet with Cumulative will be greatly improved. 74% of planning standards if 100% of the benefits planned pumping drainage capacity flood drainage works as planned are will be achieved after completion of completed. the Project and some of the linked projects. 7.3.2.3 Analysis of Reduction of Inflowing Pollutants In accordance with the VEC assessment indicator system, the major assessment indicator of cumulative impacts on water environment is the reduction of pollutants of COD and NH3-N flowing into the main watercourse of He River. As a part of the assessment, a quantitative analysis was conducted over the reduction of COD and NH3-N in 2023 and 2030. The wastewater discharge standard adopted by the various WWTPs for the long term (2030) is uncertain and that currently in force is selected. - 218 - Based on the calculation in section 5.1, the reduction of pollutants flowing into He River Watershed is shown in Table 7-7. Table 7-7: Reduction of water pollutants under the Project Treatment capacity Project component Pollutant Pollutant reduction (kg/d) （m3/d） COD 3450 Jiangnan WWTP 15000 NH3-N 405 After the completion of planned urban WWTPs and rural wastewater treatment facilities in the related development activities, the wastewater treatment capacity of Hezhou urban area and townships along He River will be greatly increased to reduce inflow pollutants. The capacity of these WWTPs is calculated based on the current size and design scale. The scale of rural wastewater treatment facility is uncertain. The designed scale is 50-80 m3/d each set. In order to evaluate the maximum impact from the implementation of the related activities, it is assumed in this assessment that the treatment capacity is 80m3/d each set. Expansion by 2030 is not considered. The influent concentrations of COD and NH3-N are 280 mg/L and NH3-N 32 mg/L respectively for the inflowing pollutants before the various WWTPs / facilities are completed. After the completion of these WWTPs and facilities, the effluent concentrations of COD and NH3-N will reach 50mg/L and 5 mg respectively, meeting the Class 1A standard specified in the Discharge Standard of Municipal Wastewater Treatment Plant (GB18918-2002). The reduction of COD and NH3-N in 2023 and 2030 is estimated based on the treatment volume and concentration of pollutant as shown in Table 7-8. It can be seen in Table 7-9 that the Project together with other urban WWTPs and rural wastewater treatment facilities will produce significant benefits of pollutant reduction. By 2023, the cumulative reduction of COD and NH3-N will reach 17,765 kg/d and 2,085 kg/d respectively. By 2030, the cumulative reduction of COD and NH3-N will reach 45,365 kg/d 和 5,325 kg/d respectively. If the possibility of stricter discharge standard to be enforced in the future, the benefits from reduction of pollutants will be greater.

The cumulative reduction of flood losses in 2030 is quantitatively evaluated based on the feasibility study report of Hezhou Urban Water Infrastructure and Environment Improvement Project and Guangxi Hezhou Urban Flood Control Planning. The annual average flood control benefits of the Project and other linked projects are CNY 130.32 million and 72.0533 million respectively, totaling 202.3733 million. The cumulative benefits of flood alleviation is remarkable. The Project and other linked projects can also improve water environment, thereby improving investment environment. These projects will contribute to promotion of economic development, especially tourism and modern service industry. Therefore, theses cumulative impacts will bring social and economic benefits. The implementation of linked projects will also produce negative social impacts similar to the Project. The dike construction, river rehabilitation and drainage pump stations construction components might involve permanent acquisition of land and the lake, river and WWTP construction works (e.g. Xiufeng Lake, Yucai River and Aimin River) to be constructed will also involve permanent land acquisition and resettlement. These social impacts might be cumulated with the Project. Total of 7 rural and 2 urban residents resettlement sites are planned under the Project. The land acquisition and house demolition shall also be properly handled during the implementation of the - 220 - linked projects. The relevant government departments shall ensure that the resettlement house construction will be completed before the demolition and proper measures are implemented for the transition period from house demolition and relocation. It may affect the progress of the Project and lead to social conflicts if the resettlement issue cannot be resolved properly. On the other hand, when the linked projects are constructed concurrently with the Project, the impacts of earth stacking and increased traffic may be cumulated. During construction period, the increased vehicles may affect traffic in the areas along the mainstream. It may lead to traffic congestion and cause cumulative social and economic impacts if the linked projects nearby are constructed at the same time. Therefore, it is necessary to take proper traffic organization and management measures to mitigate cumulative impacts during construction. 7.4 Recommended safeguard measures As discussed in section 7.3, the cumulative impacts of the Project and the linked projects are basically positive, but land acquisition and demolition may cause certain negative impacts. As the Project and linked projects involve various government departments, the multi-departmental mitigation measures are proposed under this assessment to safeguard the cumulative benefits mentioned above and minimize negative social impacts. These measures aim to strengthen enforcement capability of the various departments and promote smooth interdepartmental communication. 1. Establishing a flood early warning system and conducting trainings to promote smart water resources management. The responsible authority is WRB. 2. Strengthening water quality monitoring and regularly tracking the water quality of He River. Hezhou EPB is responsible for setting up monitoring section at Hejie and Fulong ferry and conducting artificial monitoring on a monthly basis. 3. Taking actions to ensure the construction of resettlement houses. The Project should be properly coordinated with the construction of resettlement houses. Demolition shall be conducted only when the construction of resettlement houses is completed. If there are difficulties, a subsidy plan for the transition period should be developed and implemented in a reasonable and effective way so as to complete the construction of the resettlement houses and achieve resettlement of affected people at the earliest possible time. The departments involved include resettlement office of Hezhou urban area and Hezhou WRB. 7.5 Stakeholder participation in the cumulative impact assessment The stakeholders, including relevant departments and APs (outside of the Project influence area) in the area of the assessment, were identified at early stage considering all activities might produce cumulative impacts with the Project. The main departments involved are Hezhou Planning Bureau, Hezhou WRB, Municipal - 221 - Engineering Administration Bureau (MEAB), EPB and resettlement office if land acquisition and demolition is involved. The stakeholder participation during the cumulative impact assessment process is conducted in the following manners: � Collecting relevant planning and information from stakeholders to screen key VEC through consultation with relevant departments and determine the temporal and spatial scope of the assessment. � Consulting the relevant departments and collecting their feedbacks when the draft assessment is ready. � Consulting the relevant departments and collect their feedbacks when the safeguard measures are proposed to promote inter-departmental communications and cooperation during implementation. In addition to consultation with relevant departments, the potential affected public (outside of the Project influence area) were also interviewed.

LAR social impacts and mitigation measures 8.1 Land acquisition and resettlement of the Project Here summarized as follows is the information of LAR under the Project based on the Resettlement Plan for the proposed World Bank Loan Hezhou Urban Water Infrastructure and Environment Improvement Project prepared by Guangxi Guoye Project Management Consulting Co., Ltd., in November 2017. The Project involves a permanent land acquisition of 3760.41 mu, including 47.13 mu state-owned land and 3713.28 mu rural collective owned land (with 2222.01mu arable land) and will affect 759 families and 4563 persons. Buildings to be demolished involve a total floor area of 164,194.71 m2 and an affected population of 3632 of 814 households, including 93207.60 m2 for residential houses, affecting 690 families and 3105 persons. (Rural residential houses to be demolished involve a total floor area of 55,742.29m2 and affect 373 families and 1837 persons; urban residential houses to be demolished involve a total floor area of 37465.31m2 and affecting 317 families and 1268 persons). Ancillary and temporary buildings to be demolished involve a total area of 49,278.64 m2. Buildings in a total area of 14,249.54 m2 owned by enterprises and institutions will be demolished. State-owned shops in a total area of 7,458.93 m 2 will be demolished, affecting 124 tenants. Involving a total area of 1045.67 mu, the temporary land occupation under the Project will affect 307 families and 1849 persons. The related ground attachments and infrastructures, such as fence walls, toilets, and bamboo, power and communication facilities will also be affected. The total population to be affected under the Project is 10044 persons from 1880 families, including 273 persons from 83 families identified as vulnerable groups. 8.2 Measures for mitigating social impacts under the Project Land acquisition and resettlement represents the most significant social impact under the Project. In order to minimize the scope of land acquisition and resettlement and the impacts from the construction activities on local people, measures have been taken, such as optimizing the design proposal. In the preliminary design and feasibility study period, in order to avoid or minimize land acquisition and resettlement, the social assessment team and the design institute have conducted extensive field survey and close consultation with the local officials and residents. Measures, such as optimizing the project design, strengthening project management, improving construction technology and public consultation and participation have been taken to minimize the adverse impact of land acquisition and resettlement. In addition to the measures to reduce land acquisition and resettlement during feasibility study and preliminary design stage, compensation and resettlement plans are developed for permanent land acquisition and resettled people. The compensation standard for permanent land acquisition is based on the relevant regulations and policies of PRC, GZAR, Hezhou city and the Environmental and Social Safeguard Policy (2016) of the World Bank. The resettlement plan is developed on the basis of consultation with local governments and APs and current practices. - 228 - Livelihood restoration program is developed for the farmers whose farmland will be acquired. Compensation and resettlement plan are developed for the rural relocated families, urban relocated families, non-residential relocated families, affected enterprises and institutions, affected ground attachments and infrastructures and affected vulnerable groups. Livelihood restoration plan is also developed for women to protect their right and interests. The specific compensation standards and measures are presented in the Resettlement Plan for the World Bank Loan Hezhou Urban Water Infrastructure and Environment Improvement Project. The LAR and social impacts and mitigation measures are summarized in Table 8-1. - 229 - Table 8-1: Summary of LAR and Social Impacts and Mitigation Measures Type of Eligible beneficiary of Responsible Degree of impact Compensation policy and standard impact compensation agency 1.

The stakeholders of the Project can be divided into three different categories, i.e. governmental departments, construction unit/contractor and APs. The resettlement consultant team conducted equal consultations with the APs in the project area to inform them of all aspects of the Project. 91.17% of the public are very supportive or supportive to the implementation of the Project. Only 8.83% of the consulted persons hold neutral attitude to the Project. Basically, no one expressed objection to the Project. 72.06% of respondents believe the Project would be very beneficial or beneficial. The stakeholders in the project area have understood the project information through public consultation and expressed their support to the Project. Meanwhile, concerns were also expressed over possible reduction of income and temporary impacts from the construction activities on their livelihood. In order to properly and promptly address the issues and demands of the APs, public consultation will continue before the commencement of the project construction and implementation of the resettlement plan so that all the problems may be resolved. The implementation agencies shall organize resettlement workshops/meetings appropriately. For details, please refer to Chapter 10 for arrangements of public consultation during the implementation of the Resettlement Plan (RP). 8.4 Institutional arrangement and development 8.4.1 Resettlement-related institutions In the implementation process of the Project, a top-down organization structure must be developed to plan, coordinate and monitor the resettlement activities. See Figure 8-1 for the organization chart. - 235 - PLG Municipal PMO Babu District Pinggui District Hezhou EPB HDAO HDAO WRB; MEAB Resettlement LAG ... LAG LAG ...

Project leading group (PLG) The Project Leading Group of World Bank Loan Hezhou Urban Water Infrastructure and Environment Improvement Project is the highest leadership agency in the implementation of the Project to provide policy guidance and facilitate coordination at municipal level to support the implementation of the Project. 2. Project management office (PMO) Hezhou World Bank Project Management Office is headed by Hezhou Municipal Development and Reform Commission (DRC) and fully responsible for the overall plan of and providing guidance on the land acquisition and resettlement work of the Project. Its specific duties include: providing guidance on the resettlement work in accordance with World Bank’s Resettlement Policy, submitting reports on resettlement work to the World Bank, conducting preliminary review of the resettlement plan and implementation plan submitted by project owner and submitting such plans to the municipal government for approval; supervising and inspecting the status of implementation of resettlement plan and payment and use of compensation - 236 - fund; supervising and reporting to the World Bank the progress of resettlement implementation; and conducting internal monitoring. 1. Urban land acquisition and resettlement office (HDAO) The Project will involve Babu District and Pinggui District and the Urban Land Acquisition and Resettlement Office (HDAO) is responsible for the specific work of land acquisition and resettlement. Its specific responsibilities include: developing resettlement plan and implementation plan; properly carrying out the resettlement work following the plan of PMO; inspecting the status of implementation of resettlement work; iv) soliciting comments from the relevant departments and individuals and address complaints and appeals promptly; submitting timely report to World Bank on issues, comments and suggests encountered in the process of land acquisition and resettlement and assisting PMO in internal monitoring. 2. Village committee resettlement working group The major responsibilities include participating in socio-economic and project impact survey; organizing public consultation; disseminating resettlement policy; organizing public hearings; selecting resettlement sites; allocating housing land for AFs; allocating and managing compensation fees; organizing production and training activities; delivering comments and suggestions of AFs to the higher authority; reporting the resettlement progress; and providing assistance to the vulnerable groups. 3. External independent monitoring and evaluation agency The independent external monitoring agency is responsible for monitoring resettlement work, collecting comments and feedbacks from the affected institutions and persons in a timely manner; and reporting and submitting recommendations to the PMO and IAs. The specific duties include: investigating the social and economic conditions in the planned area and preparing and submitting social baseline survey report to the World Bank; estimating the specific impacts and progress of livelihood restoration; analyzing data collected and monitoring the whole process of implementation of the resettlement plan; preparing and submitting to the PMO and implementing agency the resettlement progress report; and preparing and submitting half-year monitoring reports to the World Bank; carry out resettlement assessment at least twice a year and reporting to the project owner and the World Bank. 8.5 Grievance redress mechanism The APs will sign the agreement to confirm their rights and entitlements if they are satisfied with the proposed compensation. A procedure for information disclosure in the process of resettlement is helpful to increase the transparency of the Project. Through information disclosure, the APs will be informed of the multiple complaint channels (including village committees, departments, PMO, land acquisition and demolition office, external monitoring agency, government petition office, and court) and a variety of ways (such as petition and telephone) to express complaints and appeal. In the process of development and implementation of the RP of the Project, great - 237 - attention will be paid to the participation of APs and a grievance redress mechanism will be established to handle complaints and appeals from the APs in the following procedure: Stage 1: If not satisfied with the resettlement plan, the APs can express their complaints to the village committees in oral or written form; oral complaints must be handled and recorded in writing by the village committees or street offices / town or township authorities. Such complaints shall be addressed within one week by the project group at village level, village committee, or street / township authorities. Stage 2: If the APs are still not satisfied with the resolutions made in Stage 1, an appeal can be filed to the PMO after such resolution is received and the PMO shall make a further resolution within 2 weeks. Stage 3: If the APs are still not satisfied with the resolutions made in Stage 2, an appeal can be filed to the HDAO after such resolution is received and the HDAO shall make a further resolution within 2 weeks. Stage 4: If the APs are still not satisfied with the resolutions made in Stage 3, an appeal can be filed to the External Monitoring Agency after such resolution is received and the External Monitoring Agency shall make a further resolution within 2 weeks. All the complaints and appeals (in oral o written form) shall be reported to the World Bank in the resettlement monitoring report. Stage 5: If the APs are still not satisfied with the resolution made in Stage 4, an appeal may be filed to the government petition office after such resolution is received. The petition office shall make a further resolution within 2 weeks. The APs may directly file a lawsuit to the civil court if he / she is not satisfied with the existing GRM procedures or resolutions made in any of the above stages. 8.6 Monitoring and evaluation arrangements In order to ensure the smooth implementation of land acquisition and resettlement work and proper resettlement of the APs, the resettlement progress will be monitored and evaluated regularly in strict accordance with the terms specified in World Bank’s Operation Policy (OP 4.12) of Involuntary Resettlement and Guidance on Resettlement Monitoring and Evaluation for Business in PRC. Such monitoring shall comprises of two parts, namely the internal monitoring carried out by the resettlement agency and the external independent monitoring. The internal monitoring will be conducted by the PMO to ensure the resettlement activities are carried out in accordance with the principles and timetable specified in the Resettlement Plan. The purpose of internal monitoring is to enable the resettlement institutions to maintain excellent functions during implementation. The external monitoring refers to the regular monitoring and evaluation on resettlement activities conducted by the independent monitoring agency (IMA). This external monitoring shall be undertaken by a competent IMA. - 238 - After the completion of the project, post-project evaluation will be conducted on the basis of monitoring and evaluation results to evaluate the experiences and lessons for reference in terms of land acquisition and resettlement for future projects. The owner of subproject will commission the external monitoring agency to conduct post-project evaluation. The post-project evaluation agency will develop a terms of reference and evaluation indicator system for the post-evaluation, conduct social and economic survey and preparing and submitting the LAR post evaluation report to the PMO and World Bank. - 239 - 9. Alternative Analysis 9.1 Purpose and principles The purpose of alternative analysis is to minimize the environmental impact by optimizing the project design from environmental perspective through comparative analysis of a number of alternatives that may be selected for the Project. The general principles for alternative analysis include: 1. Quantitative comparison: quantifying the environmental impact from project implementation as much as possible for each alternative; 2. Comprehensive comparison: conducting a multi-dimension comparison and analysis of the alternatives from the environmental, technical, economic, and social perspectives; 3. Compatibility comparison: The selected alternative shall be compatible with relevant development planning and standards and the local conditions. 9.2 With-/Without-project analysis Without-project alternative refers to the scenario where the project will not be implemented. Analysis was conducted from the perspectives of environmental benefits and costs and social and economic development, with results summarized in Table 9-1. Table 9-1 With-/Without- Project Comparison Category With-Project Without-Project (1) Improved urban safety, improved flood risk control capacity. The flood control standard of He River main watercourse is improved to floods with a recurrence period of 50 years; flooded (1) The current status can be area is reduced by 13.1 km2.

(3) Improved hydrology and municipal infrastructure. (1) Flood control dikes are incomplete. At the discharging points of drainage system the elevation is low. When the water river in the He Rive is high, backflow occurs easily. In the event of a flood with a recurrence period of 50 years, the consequences will be a flooded area of 13.1 km2 and an economic loss of CNY 2044 million.

(3) During construction there will be In addition, domestic sewage from impacts on traffic and daily travel of local residents are discharged into local residents. the canals, resulting in poor water quality in dry seasons featuring in high turbidity and strong odor. Pollutants such as ammonia and TP are worse than Class V standards, making He Rivers “black and stinky water bodies�. Without sewage interception along the He River, sewage is discharged into He River without proper treatment, causing deteriorating water quality. From social and environmental perspectives, the with-project alternative is more Summary preferable than the without-project alternative. It is shown from Table 9-1 that, although the without-project scenario does not generate additional environmental impacts from project construction, problems of poor flood dike, discharge outlets of low elevation, covered-up urban inland canals and decreasing flood storage capacity still exist. A flood with a recurrence period of 50 years in He River would end up with a flooded area of 13.10 km2 and a total economic loss of CNY 2044 million. A flood with a recurrence period of 20 years in He River would end up with a flooded area of 3.1 km2 and a total economic loss of CNY 248.74 - 241 - million. The narrow urban inland canals restrict their flood carrying capacities and continuous discharge of domestic sewage from residents along He Rivers without any treatment would end up with deterioration of water quality in He River. For the with-project alternative, although implementation of the Project will bring some environmental impacts, most of these impacts, except the irreversible ones from permanent land acquisition, can be avoided or mitigated through proper environmental protection measures. Implementation of the Project will end up with improved flood management capacity of He River and help reducing the economic loss by CNY 204.4 million in the event of a flood with a 50-year recurrence period. In addition, it will also be helpful to improving Hezhou’s city appearance and protecting the people's health and protect the water quality of He River and promote integrated rehabilitation of the He River and the urban inland canals. The amount of COD and NH3-N discharged into He River will be reduced by 1259.25 t/a and 47.83 t/a. The amount of sewage interception along Huangtian Branch Canal, Guposhan Drainage Canal, Huangansi Drainage Canal and Shizigang Drainage Canal may reach 15,000 m3/d and the amount of COD and NH3-N discharged in an uncontrolled way into He River will be reduced by 1888.88t/a and 221.75t/a, contributing remarkably to rehabilitation of black and odor urban waters. Therefore, this alternative will be helpful to protection of ecological safety and improvement of Hezhou’s urban environment. Polluted rivers will be converted into livable landscaping areas and value of local land will be increased. In addition, the Project can also facilitate the urban and rural economic and social development and generate significant social, environmental and economic benefits. Therefore, from the perspective of promoting social and economic development and environmental protection, the with-project alternative is better than the without-project alternative and the project implementation is necessary. 9.3 Dredging alternatives The Project involves dredging of various rivers and drainage canals. Four different dredging methods were considered as shown in Table 9-2.

For the Huangansi Drainage canal, and Shizigang Drainage canal, Recommended Alternative 4 is recommended. For Huangtian Conclusions alternatives Branch Canal, Guposhan Drainage canal,and East Trunk Canal, Alternative 3 + Alternative 4 is recommended as the construction space is available. For different rivers and drainage canals, different dredging methods can be used. Involving huge dredging load, He River, with wide river surface and favorable depth, have the conditions needed for operation of large dredging vessels. Alternative dredging methods include cutter suction dredgers or grab dredger. The recommended option is the cutter suction dredgers because of its higher dredging efficiency, shorter dredging duration, insignificant disturbance to water body and the reduction of duration of impacts from the sediment dewatering site. For Huangtian Branch Canal, Guposhan Drainage Canal, Huangansi Drainage Canal and Shizigang Drainage Canal, due to work space restrictions, large dredging vessels cannot be used. The alternatives include direct digging or suction dredging. Because the urban inland canals have poor water quality and stinky sediments due to perennial reception of sewage; in addition, located in the densely-populated urban area, in-water suction method is recommended in order to reduce the odor impacts on the environmentally sensitive sites. For Huangtian Branch Canal, Guposhan Drainage canal and the upstream section of East Trunk Canal, Alternative 3 + Alternative 4 is recommended, i.e. construction plant dredging plus suction dredging, as these construction sites are located far away from the residential areas and mostly farmland and unused land. 9.4 Alternatives for hydropower station improvement - 244 - In the feasibility study stage, several alternatives are proposed and compared for improvement of Huangshi Hydropower Station, Fanglin Hydropower Station and Xiadao Hydropower Station. The results of such comparison are summarized in Tables 9-3 to 9-5.

Conclusions Alternative 1 is recommended. Based on the above comparisons, Alternative 1 will reduce the impact of the gate dam on the flood carrying capacity, reduce the upstream flooding loss (which increases by approximately CNY 0.5 million each year), and avoid difficulties in flood control. At the same time, with the gate dam of the hydropower station upgraded, an upstream waterfront landscape will be created and the flood regulating capacity will be improved. The environmental benefits will be improved thanks to improvement of flood carrying capacity. The disadvantages are that the long construction duration will lead to loss of revenue from power generation and generate some environmental impacts, most of which are temporary. In Alternative 2, the government becomes the owner after buy-back, therefore only the buy-back cost will be needed and compensation to losses due to power generation suspension is not needed. However, this alternative has the disadvantage of too much uncertainty due to long implementation time. In Alternative 3, the construction period is very short. However, after the removal of the gate dam, power generation will be permanently terminated, resulting in a yearly loss of approximately 1 million KW in power generation and 15 jobless employees of the hydropower station. These are permanent impacts and can cause greater social impacts than Alternative 1. After the comprehensive comparison, Alternative 1 is recommended (upgrading the hydropower station gate dam).

Recommended Alternative 1 alternatives In Alternative 1 for Fanglin Hydropower Station upgrading, the length of upstream back water is reduced through demolition of the existing concrete water gate. Compared with the other alternatives, Alternative 1, with no requirement of resettlement, features the best savings on investment, shortest construction period and relatively insignificant environmental impacts from construction. Its disadvantages include the high buy-back cost, the loss of power generation and the need of reemployment of unemployed power plant staff, and the impact on upstream irrigation leading to the addition of a new irrigation pumping station, the unresolved bridge safety issue, and the remaining back water effect from the bridge making necessary the increase of downstream dike elevation. However, compared with Alternative 2 and 3, this alternative is advantageous in its significant savings on investment, zero need of resettlement, and shortest construction duration and can generate some flood control benefits. Therefore, Alternative 1 is recommended for its highest cost-effectiveness and best price performance. - 251 - Table 9-5 Comparison of alternatives for Xiadao Hydropower Station Alternative 2: Alternative 1: Alternative 4: keeping the power Alternative 3: Keeping the power Keeping the power Alternative 6: station after the Keeping the power station and station after buy-back Alternative 5: Upgrading Upgrading the Content buy-back and station and building increasing the and building the power station power station after increasing the additional flood upstream dike additional flood buy-back upstream dike channel height channel height Keeping the power Keeping the power Power station Keeping the power station: building an Power station station: reducing the After power station buy-back: station: increasing additional flood buy-back: increasing crest elevation of gate buy-back, upgrading increasing the Description the upstream dike channel to remove the upstream dike dam to reduce the hydropower upstream dike height and keeping backwater and then height as in backwater; changing station as in height as in the power station keeping the power Alternative 3. gate type from flap gate Alternative 3 Alternative 1 station to flat gate CNY 39.35 million CNY 64.1 million (including CNY 0.5 (including CNY 4.6 CNY 85.35 million CNY 10.1 million CNY 110.1 million million for gate million for land (including CNY 53.5 (including CNY 2.6 CNY 57.4 million (including CNY 53.5 demolishing, CNY 30 acquisition, CNY 52 million for buy-back, million for new dike, RMB (including million for buy-back, million for gate upgrade, million for additional CNY 0.5 million for CNY 7.5 million for CNY 53.5 million CNY 4.6 million for CNY 1.35 million for Engineering cost flood channel, CNY gate demolishing, compensation of for buy-back and land acquisition and additional dike, and CNY 7.5 million for CNY 30 million for power generation CNY 2.6 million for CNY 52 million for 7.5 million for compensation of gate upgrade, CNY shut-down during new dike) additional flood compensation of power power generation 1.35 million for construction) channel) generation shut-down shut-down during additional dike) during construction) construction) Due to backwater Due to backwater Due to backwater effect, it is Due to backwater effect, effect, it is No backwater from No backwater from effect, it is necessary to it is necessary to necessary to the water gate. the water gate. necessary to Flood control benefit increase the increase the height of a increase the height Upstream dike is still Upstream dike is still increase the height height of a 4.0m 1.8km long dike by of a 4.0m long dike needed. needed. of a 1.8km long dike long dike by 0-0.37m. by 0-1.0m. by 0-0.37m. 0-1.0m.

Conclusions Alternative 1 is recommended. - 254 - In Alternative 1 for Xiadao Power Station Upgrading, upstream dike height is increased to satisfy flood control requirements in the upstream areas. Increase of dike height involves relatively low cost. Advantages in reduced upstream flooding loss and avoided flood regulation difficulties assure the feasibility and implementability of the alternative. The upstream area of Xiadao Power Station is dominated by low hills and features in higher planned land elevation. Increasing the dike height will have little impact on local flood drainage and control and involves a very low cost. With the impacts from water construction activity on water environment avoided and with no land acquisition and resettlement required, Alternative 1 for Xiadao Power Station Upgrading features in the biggest savings on investment and is therefore recommended. 9.5 WWTP Alternatives Different alternatives for the proposed Jiangnan WWTP are compared in terms of siting, treatment process and outlet locations. Results of such comparison are shown in Table 9-6 to 9-10 as follows.

The Disadvantage: some protection distance to surrounding area is not filling works are needed as the terrain is low and sufficient. flat. Conclusion Alternative 2 is recommended. From the comparison above, Alternative 2 is better because it allows easy sewage collection; although pipeline investment is relatively higher, Alternative 2 involves little house demolishing and resettlement and no impacts on environmentally sensitive sites as there are no sensitive sites in the protection area. Therefore the site described in Alternative 2 east of planned Jiangnan district and Luo-Zhan Railway, south of He River and west of Gubo Village and Songbaizhai Village is recommended as the WWTP site.

Stable complexity in management quality and maintenance and Disadvantage: Involving larger area of greater possibility in unstable effluent quality. land occupation Conclusion Alternative 1 is recommended. It can be seen from the above comparison that, compared with the MBR process, the A2/O micro-pore aeration and oxidation process involves a low process investment, less difficulty in operational management, greater savings on operational cost and more stable effluent quality. Although it will generate some odor impacts and noise impacts, such impacts can be contained within the plant area if appropriate measures are taken. Therefore, Alternative 1, i.e. the A2/O micro-pore aeration and oxidation process, is recommended as the treatment process for the WWTP under the Project.

Conclusion Alternative 2 is recommended It can be seen from the above comparison that Alternative 2 for the location of the discharge outlet of Jiangnan WWTP requires installation of longer sewer pipelines and greater buried depth. Despite of the construction difficulty, this alternative involves greater long-term environmental benefits because the discharge outlet is located at the lower reaches of He River and downwind direction of residential areas in the suburb. Pollutant load from the effluent can be quickly diluted and purified once it enters He River. In the other alternatives, diffusion and self-purification of pollutant in the effluent are difficult. Therefore, the outlet at the lower reaches of He River is recommended as the discharge outlet of Jiangnan WWTP. - 259 - 10. Public Participation and Information Disclosure 10.1 Purpose of public participation The purpose of public participation is to improve the quality of EIA, to provide more information and advice, and to make the EIA process more open and public so as to enable all the people with direct or indirect connection with the Project to participate in the EIA process to ensure transparency and credibility of the EIA results and to bring forward their own views and opinions to make the EIA process better and fairer. Public participation is an important part of EIA process and an effective way to improve scientific decision-making. Public participation for construction projects is an important means of enhancing the two-way communications between project construction units, EIA consultants and the public. Through extensive public participation, the public directly or indirectly affected by the construction project can have a full understanding of the potential environmental impacts, mitigation measures and the economic and social benefits brought by the project construction, and can provide feedback opinions and actively offer suggestions to jointly find a solution for potential problems. Thus the impact of project implementation on the environment can be minimized, potential pollution induced conflicts can be avoided, and environmental protection and economic development can be better coordinated. The main purposes of public participation include: (1) Summarizing and analyzing public opinions, so that they can be included in the environmental protection measures. Public opinions should also be used as the work guidelines in the implementation stage of the Project. (2) Conducting two-way communication between the public and the construction unit, introducing project overview, potential pollution, control measures, EIA prediction results, etc., to the public in detail and collecting public opinions and suggestions, etc. and giving feedback to the construction unit so that the project design can be properly modified to bridge the public and the construction unit for mutual understanding. (3) Soliciting, through public participation, public views and opinions of the Project, finding a basis for safeguarding public interest, fully adopting the feasibility suggestions in the EIA process to ease public concerns induced by lack of communications between the construction unit and the public, and mitigating as much as possible the adverse impacts on and making necessary compensation for public interests. (4) The post-EIA assessment mainly relies on public supervision. Public participation is an important part of environmental management mechanism, which is conducive to protecting the ecological environment, improving the environmental and economic benefits of the Project, and improving environmental quality, and ensuring the implementation of sustainable development strategies. - 260 - 10.2 Scoping and stakeholder identification Guangxi Hezhou Urban Water Infrastructure and Environment Improvement Project plans to apply for a loan from the World Bank to further accelerate infrastructure development under the Project, and create conditions for coordinated social and economic development in the region. Implementation of the Project will facilitate improvement of water environment in He River Watershed and Hezhou Municipality, watershed ecological function and city style and quality as well as local peoples’ livelihood and lay a solid foundation for sustainable development in Hezhou. However, during project construction and operation, there will be some environmental impacts on the surrounding area concerning the personal interests of local people. Such impacts will cover individual residents and organizations within the range of red lines (RoRL) and in the affected areas of the Project.

As the construction and operation of the Project involves land acquisition, resettlement, and possibly local environmental changes, two rounds of public participation were carried out for the Project according to the requirements of domestic laws and regulations for environmental protection and the World Bank Safeguard Policy (OP4.01). The first round was in the preparation phase, or during the preparation of the EIA outline; the second round was after the draft EIA report was finalized. The public participants mainly include residents in the project area or project-affected area, i.e., the residents near the sections of He River and urban inland canals to be rehabilitated and the WWTP to be built. In addition, the public participants also include representatives and experts from government agencies related to the Project The first round was conducted in the project preparation phase or during the preparation of the EIA outline. The main purpose was to introduce the basics of the Project so that the public could have a basic understanding of the Project and make comments or suggestions for project implementation. During this round, the EIA consultant solicited comments and suggestions from the public through online information disclosure, poster disclosure, interviews, questionnaires survey and seminars. Such comments and suggestions were delivered as feedbacks to the Project EA and feasibility study designer to provide references for the project design as this EIA. The second round of public participation was implemented after the first draft of the EIA Report was completed. The main purpose was to provide feedbacks on comments and suggestions solicited during the first round, and solicit comments and suggestions on the proposed mitigation measures. During the second round, the EIA consultant also solicited comments and suggestions from the public through expert consultation, online disclosure, poster disclosure, interviews and seminars. At the same time, the draft EIA report was made available at places of public accessibility including offices of the PMO, HEPB, relevant village committees, or street committees, etc. Details of the public participation are summarized in the Table 10-2 and Table 10-3. The process is illustrated in Figure 10-1 and Figure 10-2. - 265 - Table 10-2 Summary of comments and feedbacks for the first round of public consultation Time Venue Method Objects Contents Public comments/opinions Feedback to public comments First Round Government Introducing basic agencies, Timely communication will be assured with the FSR information and village The design should be optimized to design institute to provide feedback to them so that potential committee avoid land acquisition and land acquisition and resettlement can be avoided as 2016.4.1 environmental HDRC Seminar leader and resettlement.

Feedback: Improvements will be made to the project design and preparation to enable early commencement of the construction works. The construction will strictly follow the design and construction plan and the pollution control measures. The contractors should make all efforts to complete the construction works at one go as soon as possible and avoid repetitive construction. 3rd Issue: Arrangement of sewage discharge in the surrounding area. Currently there are no complete sewage collection system in Xiwanzhai and Fanglin Villages (Hezhou Experimental Middle School). The sewage is discharged to He River after treatment in septic tanks or small-scaled treatment facilities. The performance of these small-scaled facilities is not stable and the operational cost is very high. Therefore it is suggested to improve the drainage system for these areas, so that the sewage can be collected and sent to WWTPs for treatment to avoid river pollution. Feedback: The Xiwanzhai Village is within the service area of Pinggui District WWTP already in operation. The sewer system for the WWTP is being improved and will cover Xiwanzhai Village very soon. The sewage from Fanglin Village will be sent to the planned Pinggui District WWTP. 4th Issue: Mitigation measures for construction noise. There are four schools (Hezhou Experimental Middle School, Pinggui No.3 Middle School, Yingshi Primary School and Xiadao Primary School) in the close neighborhood of the project area. Will the teaching activities in these schools be affected? Feedback: For Hezhou Experimental Middle School, temporary sound barrier will be established. For Yingshi Primary School, the entire school will be relocated. For Pinggui No.3 Middle School and Xiadao Primary School, the construction area will be separated by the sport grounds from the schools teaching buildings and dormitory buildings, therefore the construction activities will have no impact on regular teaching activities. - 293 - 5th Issue: The protection plan for the Babu Special Branch of CCP in Xiadao Primary School. Feedback: It is confirmed that the Babu Special Branch Historic Site in Xiadao Primary School is a cultural heritage protection unit. It is an important existing “red culture� heritage in Hezhou, and a base for promoting patriotism education and red culture-based tourism. Therefore it has high value and should have in-situ protection. It is planned to adjust the original dike protection plan from T-shaped revetment to vertical retaining wall to reduce the construction area and avoid this cultural relics site. Public comments and suggestions are summarized in Table 10-2, which have been taken into account by the EIA consultant and feasible adjustment suggestions and pollution control measures were proposed on such a basis. 10.3.3 Statistics of Public Participation Questionnaire Survey The targets of the survey are the residents in the affected area.

These include: (1) In March 2016, the World Bank dispatched its first Pre-Identification Mission to conduct its preliminary project identification. The Mission also provided guidance for the social safeguard related works and provided detailed requirements. During the land acquisition and resettlement survey conducted between March 2016 and April 2017, representatives from agencies of different levels in charge of land acquisition and resettlement, and representatives from villages and shops all participated in the survey. During the survey, the female representatives were all present and examined closely the indicators for final survey results. (2) During the periods from April 16 to April 26 in 2016, July 21 to July 27 in 2016, August 10 to August 20 in 2016, January 20 to January 24 in 2017, February 20 February 23 in 2017, March 2017, March 17 to March 21 in 2017, April 24 to April 29 in 2017, the consultants, PMO, IAs, and the Resettlement Office organized a number of meetings among representatives from different agencies and the affected people. These agencies include the land resource bureaus, planning bureaus, and housing and urban-rural development bureaus for Babu District and Pinggui District. At these meetings, information was disclosed on the existing policies on land acquisition and resettlement compensation standards at national, regional or municipal levels, and the World Bank policy document (OP/BP4.12). From the participants, comments have been solicited on mitigating project impacts, confirming compensation standards, and resettlement and livelihood restoration plans etc. Based on these comments, the design institute has adjusted the project design several times to minimize the impact of resettlement. Through extensive consultation, it is all agreed that the loss on the affected people’s side will be compensated with cash compensation or physical placement following relevant national laws and regulations. (3) During the preparation of the Resettlement Plan from March 2016 to June 2017, the resettlement consultants, PMO, IAs, design institute and other relevant agencies visited various villages and villagers, held meetings with participating village leaders and villagers' representatives, interviewed representatives of participating units and shops, to solicit their opinions on land acquisition, resettlement policies and standards, resettlement plans and restoration methods. The meeting and surveys have been helpful to the resettlement issues, compensation policies, compensation eligibilities, and restoration plans. Other topics of discussion include the siting of office buildings for resettled units, self-owned buildings or concentrated compounds for resettled farmers. (4) In order to raise the project awareness, PMO, IAs, and the Resettlement consultant conducted a questionnaire survey on the affected communities and affected people during the period from March 2016 to April 2017. The survey covered all affected villages and tenants, as well as units and shops. Therefore the sampling is representative, structurally reliable, and can truly reflect the wishes of the affected people. (5) Seminars on environmental and resettlement were held between November 2016 and February 2017. - 306 - The consultation concluded that the affected people do not want further adjustment on land related issues. For the loss of income due to loss of land, the affected people demanded for cash compensation and provision of employment opportunities, required the government to solve the permanent homestead issue as soon as possible and build the foundation with full cash compensation in place. Compared with the house demolition, the affected people cared less about land acquisition. This is because the project area is along He Rivers and main channels. The lands to be acquired are basically those lands that can be useful only when inundation is not a problem. And because these affected people are near the city, they are not willing to be working on agricultural or salt production. Therefore they hope that the Project can bring about economic transformation and new employment opportunities, and that they can get the homestead for house building, or get fully compensated in cash. All the questionnaire respondents expressed their wishes to use the compensation to rebuild the house, and most of them also want to use the compensation to start some business, or master some skills through training, or even be employed in big enterprises, instead of going back to land farming business. They want to use the cash compensation for their land loss to restore their livelihoods and income, such as: 1) the purchase of social insurance; 2) self-owned business in the tertiary industry, i.e. clothing stores, grocery stores, transport, freight, community services, repair shop, hairdressing, salon, dry cleaners, entertainment, catering and hotel services, and tourism service, etc.; 3) investment in their children's education. They hope that through training they can find jobs in other institutions, business units and business organizations. Affected people are satisfied with the compensation arrangement and the resettlement measures. However, they also expressed their concern about fair and timely payment of compensation. - 307 - Table 10-8 Record of public participation process of affected people No. of No. of Results of Time Venue Agenda (topics) Organizer Participants female participants negotiation participants Morning Conference Explain the importance PMO Representatives from PMO, 60 15 Conduct front end of March room at of the Project.

Environmental & Social Management Plan 11.1 Environment and Social Management System Hezhou Municipal Environmental Protection Bureau is responsible for the review and approval of the various subprojects of the Project according to the administrative authority stipulated in the Law of the People’s Republic of China on Environmental Protection and the Regulations on Environmental Protection Management of Construction Projects. As the environment management agency of the Project, Hezhou Municipal Environmental Protection Bureau is mainly responsible for proposing environmental protection requirements based on the contents of the EIA Report of the Project, coordinating the environment management work of the various departments and organizing the “three-simultaneousness� acceptance of the environmental protection facilities. The World Bank Loan Project Management Office is responsible for managing the implementation of the entire Project while the Project Owner is responsible for implementing the various specific activities under the general administration framework of the Project as well as the leadership of Hezhou Municipal Government. In order to assure smooth implementation of the environment management activities of the Project, a number of full-time or part-time environment management personnel are assigned in the PMO, the Project Owner, the Contractor and the Operator to implement the Environmental & social management plan. 11.1.1 Environment Management Agency As the environment management activities of the Project in the construction stage are significantly different from those in the operation stage and such activities are either short-term or long-term in terms of their deadlines, the Contractor and the Operator should set up separate organizations to take the responsibility for different stages. As the construction stage ends, the management organization of the construction stage will be cancelled while that of the operation stage will start to operate, with a certain overlapping period allowed based on the progress of the specific management activities. - 319 - World Bank EIA consultant HPMO HEPB HWRB HMEAP HEPB External Monitoring agency Contractor Construction Supervision Engineer Supervisory Management Consulting agency Agency agency Project Owner Implementation Agency Figure 11-1: Schematic Diagram of the Environment Management Agencies in the Construction Stage of the Project HPMO World Bank Consultant External HEPB Operator Monitoring agency Supervisory Management agency Agency Operating Monitoring Agency agency Figure 11-2: Schematic Diagram of Environment Management Agencies in the Operation Stage of the Project - 320 - 11.1.2 Responsibilities and Contents of Environment Management The contents of environment management in the construction stage are remarkably different from those in the operation stage of the Project and the ESMP is implemented by different responsible departments.

EIA Conclusions and Recommendations The following conclusions may be drawn from the comprehensive environmental impact assessment of the Project: （1） The Project aims to implement integrated improvement of water environment and construction of urban infrastructure under the guidelines of development, livelihood and innovation and following the standards of “green water service, eco-friendly water service and storm and flood safety�. The Project will be helpful to safeguarding regional flood protection and waterlogging drainage, improving regional water environment and building high-standard and modernized urban infrastructure and public facilities; it will provide powerful support and assurance to the sustainable economic development of Hezhou Municipality to promote the level of sustainable urban development and realize the integration of reform and innovation. Identified from the perspectives of task demand and target realization, the key design elements of the Project comprise of five engineering systems of flood risk control, urban drainage improvement, water environment improvement, ecological landscape improvement and technical assistance and management. Flood risk control --- Through improvement of the flood discharge capacity of the mainstream and tributaries, flood risks will be prevented and put under control by means of assured discharge of flood. The flood control status of the main watercourse of He River and its urban tributaries will be analyzed and an enclosed flood control system will be constructed to bring the flood control capacity of the urban area of Hezhou to the respective standard. Urban drainage improvement --- Through improvement of the storage capacity, the stormwater retention capacity will be increased for the purpose of reducing the pumping and drainage volume. The terrain and topographical condition of the urban area and the existing urban drainage system will be analyzed and measures of storage regulation and pumping will be taken to assure flood discharge safety and reduce waterlogging risks in the urban area of Hezhou Municipality. Water environment improvement --- Improvement of the water diversion and exchange system and the wastewater collection and treatment system will help improving the water quality of He River channels and lay a foundation for improvement of ecological environment in He River Watershed and final realization of the targets of water quality and ecological safety of the water systems in the region. Ecological landscape improvement --- Construction of the urban green ring and ecological corridor will be helpful to the improvement of landscape continuity, preservation of animal habitats, establishment of continuous leisure and - 507 - entertainment network close to nature, encouragement of walking and bicycle travelling and protection of natural ecology. The urban green ring and ecological corridor will become the center for protecting the urban ecological structure and functions and developing the urban ecological network and urban open space planning and will promote the value of the urban landscape system, maintain the health and life of the water environment of the water systems and facilitate human-water harmony. Technical assistance and management --- The management capacity of the various functional departments and the smart water management level of Hezhou Municipality as a whole will be promoted through construction of the water quality monitoring station and the flood warning system as well as training of the full-time staff. Upon the implementation of the Project, the main watercourse of He River will reach a flood control standard of 1 in 50 years while the urban river system will achieve a 20-year recurrence period in terms of waterlogging hazard. Effective collection and treatment of wastewater in Jiangnan District will contribute to improved water quality of the urban water system and improved urban environment quality and drive the sustainable development of Hezhou Municipality. He River shores and other low-impact development facilities will be fully utilized to reduce energy consumption, save land and alleviate pressure of water environment. Upon completion, the Project will play an extremely important role in safeguarding social stability and economic prosperity in the region and generate huge social, economic and environment benefits, making it an important project serving multiple purposes. （2） The construction of the Project complies with the national laws and regulations and the master urban plan and environmental protection plan of the project area, which are the policy and legal foundation for the implementation of the Project. （3） The implementation of the Project may involve some environmental protection objects (sensitive sites), such as residential areas, schools and physical cultural resources, etc. In the feasibility study, the Project is reasonably sited to avoid the aforesaid environmental protection objects. In the Environment Assessment, optimization of design program is achieved through analysis of the siting alternatives to mitigate impacts on the environmental protection objects. （4） Some adverse impacts are likely to arise from the implementation of the Project on the surrounding environment. Such impacts may come from the construction stage and may also occur in the operation stage. 1） Adverse impacts in the construction period mainly include soil erosion caused by excavation, exhaust gas and noise from transportation of earth and construction material on construction site and access roads, and wastewater - 508 - discharged from construction camps and sediment dewatering facilities and odor from dredging and temporary storage of dredged sediment. Additionally, social impacts include disturbance to local traffic by construction vehicles and Fanglin Hydropower Station improvement, impact by He River rehabilitation to the physical cultural resources of Xiyue Historical and Cultural Street and the site of CCP Babu Special Branch, interference with railway from He River-lake connection works, and impact on existing farmland irrigation by Fanglin Hydropower Station improvement. 2） Upon completion of the Project, the urban flood risk control capacity of Hezhou will be enhanced, the black and odorous urban waters will be eliminated and the landscape value, ecological environment and municipal infrastructure will be improved. However, adverse environmental impacts will arise, mainly including effluent, odor and noise generated in the operation of Jiangnan WWTP and noise generated by stormwater pump stations in operation. Nevertheless, the positive benefits of the Project as a whole will be far more significant than its adverse impacts. （5） The level and scope of the adverse impacts likely to arise from the Project will be controlled within the scope permitted by the national laws and regulations and standards and codes by means of alternatives, mitigation measures, ESMP implementation, public participation and consultation, involuntary resettlement, and implementation of the dam safety action plan, etc. In conclusion, the Project is feasible if the alternatives, mitigation measures, ESMP, public consultation, involuntary resettlement plan, dam safety action plan and other countermeasures proposed under the Project are executed. -

Prediction of impacts on water environment in the scenario of accidental discharge In the prediction of the impacts on rivers by the direct discharge of untreated wastewater, He River is the destination of discharge of Jiangnan WWTP Subproject. Based on the scale of He River, the two-dimensional steady-state mixed attenuation model for shore discharge and the S-P model for fully mixed section recommended in HJ / T2.3-93 "Technical Guidelines of Environmental Impact Assessment - Surface Water Environment" are selected as the prediction models. In the accidental discharge scenario for Jiangnan WWTP, the prediction is conducted on the assumption that wastewater is discharged without prior treatment (i.e. at the design influent concentration of WWTP). (1)Fully mixed river section S-P model is adopted: x c  c0 exp(  K1 ) 86400u c0  (c p Q p  ch Qh ) /(Q p  Qh ) (2)Mixing section Two-dimensional steady-state mixed attenuation model for shore discharge: x c pQp uy 2 u (2 B  y ) 2 c( x, y )  exp(  K1 ){ch  [exp(  )  exp(  )]} 86400u H �M y xu 4M y x 4M y x (0.4 B  0.6a) Bu l ; Calculation result of the length of the mixing (0.058H  0.0065B)( gHI )1 / 2 section is 3111m.

Feedbacks of Hezhou Municipal Press, Publication, Radio, Film and Television Bureau on Preservation of Xiyue Street Suggestions on Preservation of the Riverside Historical Heritage of Xiyue Street Xiyue Street is a well-known historical and cultural street in Hezhou. This street block took shape in late Qing Dynasty and reached its heyday in the Minguo era, when, in particular during the period of Anti-Japanese War, hosted a large group of historical and cultural elites of China. With many ancient wharves, ancient ferries and ancient bridges and ancient trees along the river, the old communities of Hebianxiang Street, Sha Street and Xiyue Street hosted historical and cultural elite, such as He Xiangning, Liu Yazi, let alone the large number of historical architectures and cultural relics, e.g. the former residence of the famous Hong Kong film director Liu Shiyu, Liujiadianpu and Liu Yazi and the Xianfeng Bookstore where Zhang Tiesheng and Chen Cisheng covered in the World Affairs used to live. Xiyue Street is a miniature of the history of city development of Hezhou City and is a museum of the fresh history of Hezhou that records in the true sense the evolution of urban history and carries the context of historical development of Hezhou. In July 2015, Hezhou initiated the declaration for national historical and cultural cities and Xiyue Street is one of the three historical and cultural blocks included in the declaration. The ancient embankment of the section of Shajie Wharf has been covered by the newly constructed flood control embankment. Hopefully, the surviving ancient wharves, bridges and embankment will be preserved to the best possibility in the project design and construction in the future. In such a context, the following recommendations are made: 1) The project design shall, to the maximum possibility, avoid the declared scope for preservation of the national historically famous city to preserve the ancient wharf, ancient embankment, ancient bridges and ancient trees along the river and protect the cultural heritage of Hezhou. 2) During the planning design of areas around Xiyue Street, the suggestions and advices proposed by Hezhou Office of Declaration of National Historical and Cultural City shall be incorporated and no construction activities shall be commenced until such planning design is reviewed and approved by the Municipal Government. Annex buildings of and new buildings to be constructed within the declared scope of national historical and cultural city shall have consistent style with the existing historical and cultural block. 3) Reference to the advanced experiences from Yongzhou City of Hunan Province and Wuzhou City of Guangxi ZAR is recommended. The flood dike to be constructed should be moved towards the waterfront area and the existing dike and ancient wharf should be preserved. Antique waterfront bridges and aisles may be constructed along the river banks to cover the sewage drainage pipelines along the river and improve cityscape. 4) The design style of Wuzhou and Guilin for flood dykes are recommended and the mining culture, money casting culture and red revolution culture unique in Hezhou should be presented in the form of reliefs on the existing flood dykes to enrich the urban cultural heritage of Hezhou. Riverside environment improvement should be integrated with the comprehensive urban development to not only create a new leisure space for Hezhou, but also revitalize this old and historical street. - 563 - Hezhou Municipal Press, Publication, Radio, Film and Television Bureau February 25, 2017 - 564 - 2.

The Project comprises of three components, including: (1) Component 1: He River Flood Risk Improvement, which includes: (a) improvement and rehabilitation (or demolition) of a few small runoff hydropower stations on the main watercourse of He River to enhance flood discharge capacity; (b) appropriate widening of certain sections of the main watercourse of He River to increase the flood discharge capacity and build riverside green corridors; (c) enhancing and connecting East Trunk Canal and Mawei River to divert upstream flood from the northern part of the urban area to the downstream areas and build riverside green corridor to increase flood discharge capacity and reduce waterlogging risks in the urban center of Hezhou City; (2) Component 2: Urban Drainage and Wastewater Management, which includes: (1) rehabilitation of tributaries of urban inland rivers and construction of riverside green corridors to divert regional flood; (b) construction of stormwater pipeline and pump stations in selected areas; (c) construction of Jiangnan WWTP and main sewage pipelines; (3) Component 3: institutional capacity building and project management, which includes: (a) institutional capacity strengthening and (b) project management and supervision. Impact analysis: The construction activities of He River (Guangming Bridge – Lingfeng Bridge Section) Integrated Rehabilitation Subproject, Huangan Temple Drainage Canal Pump Station Subproject and Huangan Temple Drainage Canal Integrated Rehabilitation Subproject under the Project may generate impacts on the historical and cultural street of Xiyue Street. Countermeasures to be taken: 1. The buildings (structures) in the Xiyue Street neighborhood should be designed in such a way that they have a uniform style with the existing buildings and should not be constructed until an approval has been granted by the Municipal Government. 2. The construction area included in the project design should avoid, where possible, the area of preservation of the historical and cultural street so as to preserve the ancient buildings, ancient wharf, ancient embankment, ancient bridges and ancient trees and keep the historical background of this historical and cultural street. 3. The river rehabilitation works should take account of the city style and natural background so as to create a unique cityscape. 4. The competent authorities should be consulted before construction to develop a practical and effective program for cultural relics protection. 5. A detailed construction program should be developed before construction and signs should be erected on construction sites to indicate the nature, significance, scope and measures of preservation of the respective cultural relics as well as the contact person and contact information of the cultural relics protection administration body. 6. Where construction becomes inevitable in the area of cultural relics preservation, manual excavation must be selected and no excavators, pile drivers and other mechanical equipment should be used in order to reduce vibration impacts on cultural relics in the construction process. 7. Construction camps, temporary top soil stockpiling sites must not be located in the area of protection of cultural relics. 8. Large vehicles and plants are prohibited to enter the area of preservation of cultural relics. 9. The construction contractor should provide education on protection of cultural relics to the construction workers and keep the cultural relics as far away from the construction activities as possible to avoid human damages to such cultural relics. 10. Upon the discovery of any cultural relics in the construction process, the construction activities should be suspended immediately and a report submitted to local cultural relics administration authority. The construction activities shall not resume until a notice on work resumption is received. - 565 - Does your organization agree with the measures to be taken?

Key problems: The CCP Babu Special Branch located in Xiadao Primary School belongs to the right of way of the Project. The former teaching building on the site was already destroyed and the only building preserved is a streetside building. In the 1980s, the “CCP Babu Sp ecial Branch Memorial� was built up on the former site. Due to urban development, it is difficult to preserve the former site and the proposed plan at present is to relocate the remaining school gate from the former site to a new location for preservation. Does your organization agree with the measures to be taken? Do you have any other comments or suggestions? Answer: We agree with the preservation measure to be taken and propose the addition of one more measure, i.e. “10. Preservation of the historical buildings on Xiyue Historical and Cultural Street should be carried out in reference to the standards for cultural relics�. Description of cultural relics: CCP Babu Special Branch Site Code: 451102805200000165 Year of construction: 1946, representative building of modern times According to Article 20 of the Cultural Relics Law, it is recommended that this site should be avoided to the best possibility. The CCP Babu Special Branch Site is a stronghold of CCP Babu Special Branch in the former Xiadao Primary School established in 1946 and served as the headquarter of the underground CCP leadership for Babu, Yongqing, Guiling, Nanxiang and Pinggui Mine District to spread revolutionary ideas to the massive teachers and students and local people and guide the youth towards the path of revolution. The Site of CCP Babu Special Branch is an important stronghold of activities in Hezhou in those years and - 567 - represents an important heritage of red revolution culture in Hezhou, thus embracing important value in development as a base of patriotism education and a destination of red culture tourism. What is your organization’s attitude towards the construction of the Project from the general perspective of local economic development and environmental protection?

The Project comprises of three components, including: (1) Component 1: He River Flood Risk Improvement, which includes: (a) improvement and rehabilitation (or demolition) of a few small runoff hydropower stations on the main watercourse of He River to enhance flood discharge capacity; (b) appropriate widening of certain sections of the main watercourse of He River to increase the flood discharge capacity and build riverside green corridors; (c) enhancing and connecting East Trunk Canal and Mawei River to divert upstream flood from the northern part of the urban area to the downstream areas and build riverside green corridor to increase flood discharge capacity and reduce waterlogging risks in the urban center of Hezhou City; (2) Component 2: Urban Drainage and Wastewater Management, which includes: (1) rehabilitation of tributaries of urban inland rivers and construction of riverside green corridors to divert regional flood; (b) construction of stormwater pipeline and pump stations in selected areas; (c) construction of Jiangnan WWTP and main sewage pipelines; (3) Component 3: institutional capacity building and project management, which includes: (a) institutional capacity strengthening and (b) project management and supervision. Impact analysis: 1. A certain volume of sludge will be generated from the dredging operations of He River, East Trunk Canal, Huangan Temple Drainage Canal, Shizigang Drainage Canal, Huangtian Branch Canal and Guposhan Drainage Canal; 2. Underground pipelines may be affected by the excavation activities to be conducted on the construction sites located 23m upstream of Sanjia Bridge, intersections of Huangan Temple Drainage Canal with Badaxi Road and Jianshezhong Road, intersections of Shizigang Drainage Canal with Guposhan Avenue, Wanquan Street, Zhushan Road, Badaxi Road, Yinhe Street, Jianshezhong Road, Pinganxi Road, Longshan Road, Anshanxi Road, Xingguang Road and Pinganxi Road as well as the Transportation Bureau at Jiangbeizhong Road. 3. The construction activities may generate impacts on 4 banyan trees at Xialiangzhai, 2 hackberry trees, 1 banyan tree and 1 camphor tree at Jiangbeizhong Road, 2 camphor trees and 1 banyan tree at Xinaner Street, 1 camphor tree at Jianshezhong Road, 1 camphor tree at Xinanyi Street and 1 camphor tree at Xiyue Street. Countermeasures to be taken: 1. Sludge generated from dredging of He River, Huangan Temple Drainage Canal and Shizigang Drainage Canal is dewatered to sludge cakes with a moisture content of less than 50% (in a total volume of approximately 12554m3) and then transported to Hezhou Domestic Solid Waste Landfill for treatment. Sludge generated from dredging of East Trunk Canal, Huangtian Branch Canal and Guposhan Drainage Canal is dewatered to sludge cakes with a moisture content of less than 50% (in a total volume of approximately 2058m3) and then transported to Hezhou Solid Waste Incineration Plant for disposal. 2. The following measures should be taken for excavation activities involved in underground pipeline construction: (1) communicating with and submitting construction plan to the competent authority, and finding out layout plan of underground pipelines; (2) planning the construction works in such a way that the underground pipelines are avoided where possible; (3) controlling or minimizing the construction time of pipeline construction; (4) immediately reporting the competent authority any cases of existing pipelines affected in the excavation process for emergency repair. 3. The following measures should be taken for construction activities involving famous and ancient trees: (1) minimizing the scope and construction period of construction activities; (2) making sure that the excavation operations will not affect the roots, branches and crowns of identified famous and ancient trees; (3) making sure no construction wastes, borrow fill and waste soil are stockpiled around the growing area of such trees; (4) making sure that such trees are not rolled or compacted by vehicles and construction plants. - 571 - Does your organization agree with the measures to be taken? Do you have any other comments or suggestions? We agree. Suggestion: 1) Underground pipeline survey data should be collected from housing and urban-rural development authority; a pipeline coordination team should be set up and departmental contact person defined. Construction plan should be developed based on pipeline location and depth. The owner unit of pipelines should be notified upon excavation so that on-site surveillance and emergency preparation can be facilitated (in particular with national defense and military optical cables). Formalities for temporary excavation should be fulfilled at the municipal engineering authority if any municipal roads are involved. 2) ancient trees should be protected in strict accordance with the respective measures.
