4 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
I. EXECUTIVE SUMMARY
1. Background of project scope adjustment: Approved by ADB on October 25, 2013, Anhui Huainan Urban Water Systems Integrated Rehabilitation Project (Project No.: Loan 3054-PRC) involves a total investment of US $307 million, including US $150 million as the ADB loan to be utilized for the Project. After the Project is commenced, an adjustment was made by Huainan Municipal Government (HMG) to the Master Plan of Urban Drainage (Rainwater) and Flood Control in Huainan Municipality (Year 2010 – 2020), which leads to the cancellation of the embankment and revetment and the pump station construction works of Gaotang Lake and the sewage pipeline installation works for the eastern parts of Gaotang Lake New District and Binhe New District. In addition, due to the chanllenges of land acquisition and resettlement, the Longwang Channel rehabilitation works was cancelled. In the process of procurement, large savings was achieved by low contract award price. To assure effective utilization of the ADB loan and realize the overall outcomes of the Project, it is necessary to make scope change to include new components into the Project.
β. New project components. The project components involved in the mid-term adjustment of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project (i.e. the new project components) are located in Huainan Municipality, Anhui Province, the People’s Republic of China (PRC) and the Environmental Impact Assessment (EIA) report for such new project components have been prepared in accordance with the PRC’s regulatory requirements for EIA and the Asian Development Bank (ADB) Safeguard Policy for the Environment (SPS, 2009). The project is classified ‘Category A’ under the SPS. The new project components comprise of four sub-components: (1) improved wastewater collection and Delivery System, mainly the construction and reconstruction of some parts of the urban sewage pipeline network and construction of 4 new sewage pump stations; (2) improved urban water quality and flood control, including river dredging, revetment construction and slope protection, construction of riverside flood control roads, levees, rain water pipelines, and bridges across rivers, construction of 6 new flood discharge pump stations and other hydraulic facilities; (3) improved ecological system, mainly including dredging the existing waters of three corner ponds of Shouxian County, and redesigning the lake ecosystem to enable it to have the capability of self-purification and flood retention and regulation; (4) non-structural measures, including municipal utility maintenance equipment, sanitation vehicles and equipment, and integrated water management and monitoring equipment of Jiaogang Lake, etc. The expected environmental and social benefits of the Project include upgraded flood protection and drainage capacity of the project districts and counties and reduced pollutant load into the river through wastewater collection.
γ. Status quo of regional environmental quality. The environmental monitoring
1 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment institute, Anhui Zhongwang Environmental Protection and Energy Saving Testing Co., Ltd., monitored the regional environmental quality status during 23 to 29 July 2017 including water, air, sound and soil. Analysis of the monitoring results of the environmental quality status indicates quality of the regional atmospheric environment meets Ambient Air Quality Standard (GB3095-2012) Class 2, the acoustic environment quality meets the Class II standard specified in “Environmental Quality Standard for Noise” (GB3096-2008) and all the characteristic pollutants in the sediments meet Class II standard specified in the “Environmental Quality Standard for Soils” (GB15618-1995). Seven of the monitored water bodies meet Class III standard specified in the “Environmental Quality Standards for Surface Water” (GB3838-2002), and the others could not meet Class IV standard.
4. Status quo of ecological environment. Results of literature study and field investigation show that the plants and animals in the project affected area are local common species and there are no rare and endangered and protected species. In the project affected area, there are neither designated protected areas and nor protected wildlife habitats; it has been found in the field investigation that the small egret living at the lake island in the northeastern corner pond of Shouxian County is currently identified as an ordinary species.
5. Historical and cultural relics. The three corner ponds to be rehabilitated are located within Shou County Ancient City. The ancient city wall of Shou County was initially built in 1060s and was partly rebuilt in 1987. In June 2001, the ancient city wall of Shou County was approved by the State Council as national-level protected cultural relics.
6. Key environmental impacts and mitigation measures. The key impacts on the air environment in the construction stage of the Project are from dust and a small amount of exhaust gas emitted by mechanical plants and such impacts are temporary; the Project is expected to generate short-term and intermittent impacts on the acoustic environment in the construction stage; with small impact on the water bodies, the Project will involve no impacts on the groundwater. Measures available for mitigating the environmental impacts of construction dust mainly include covering the construction materials, sprinkling water on a regular basis, and erecting fences around the construction sites, etc. Measures for mitigating the impacts of construction wastewater mainly include reasonable arrangement of construction camps and setting up sedimentation tanks relying on the existing sewage facilities and sites, etc. Measures for mitigating impacts of construction noise mainly include reasonable scheduling of construction activities, use of low noise machinery, and setting up temporary sound barriers or sound insulation panels and so on. Construction and domestic solid wastes are regularly cleaned by the local sanitation department while the sediments are transported in special tank trucks to a designated site for disposal. The topsoil and surface vegetation will be protected during construction and ecological restoration will be conducted at the end of the construction stage. With the aforesaid mitigation measures effectively implemented, the respective impacts will be significantly reduced. Dust, tail gas and wastewater will disappear at the end of the construction stage and no irreversible negative impacts are involved.

7. The main impacts on Shouxian Ancient City Wall in the construction stage will be generated from mechanical vibration and construction dust, which can be reduced if reasonable construction methods are adopted. Mitigation measures to be taken should be in harmony and consistency with the local cultural relics and landscape where possible. The above impacts will disappear as the construction activities come to an end. Negative impacts will be generated from the construction activities on the daily inhabitation of the egret found in the northeastern corner pond of Shouxian County. In this regard, special personnel will be assigned to monitor the reactions of birds in the construction stage and actions will be taken to maintain the original landform and natural state of the lake island. The abovementioned impacts will disappear as the construction stage comes to an end.
8. The main impacts in the operation stage come from pump station noise and coarse screen residues. The noise impacts can be minimized to meet the requirements of the respective national noise standards if respective mitigation measures are taken, such as greening and setting up sound enclosures in the pump station. The coarse screen residues will be cleaned and disposed by the local sanitation department. With the aforesaid measures taken, the Project will generate minimal negative impacts on local environment during operation stage.
9. Public consultation and information disclosure. Two rounds of public consultation were conducted in the preparation stage of the Project. In the first round of public consultation that started on 24 July 2017 and ended on 30 July 2017, information disclosure and questionnaire survey were conducted with the directly affected persons as the respondents. The second round was carried out from 24 August 2017 to 30 August 2017 and information disclosure, questionnaire survey and focus group discussions were organized under the participation of directly affected persons and representatives of associated institutions.
10. It is known from the results of questionnaire survey that all the respondents agree to the construction of the Project; Participants in the focused group discussions all expressed support to the construction of the project, but are somewhat concerned about the environmental impacts in the construction stage of the Project. The EA will strengthen environmental management in the construction stage by conscientiously implementing the various pollution control measures proposed in the EIA to minimize the environmental impacts in the construction stage.
11. EMP implementation. HMG will, through Huainan Project Management Office (HPMO), be responsible for the overall implementation of the Project EMP, including the management system, the mitigation measures, the monitoring plan, the training plan and the grievance redress mechanism. In the construction stage, HPMO will ensure continual public participation by providing multiple ways of public participation.
1β. Conclusion. It is concluded from the analysis that the adverse environmental impacts in the construction and operation stages of the Project will be negligible if corresponding mitigation measures are taken and the Project EMP is adequately and

II. INTRODUCTION
A. Background
1. Preliminary Project Profile
1. Anhui Huainan Urban Water Systems Integrated Rehabilitation Project (Project No.: Loan 3054-PRC) was approved by ADB on October 25, 2013. The Project involves an estimated investment of CNY 1.9 billion in total, equivalent to US $307 million, including an ADB loan in an amount of US $150 million. The Loan Agreement came into effect on February 24, 2014 and the project construction stage is five years. Anhui Huainan Urban Water Systems Integrated Rehabilitation Project (hereinafter referred to as the Preliminary Project) includes 4 components: (1) Improved wastewater collection; (2) improved urban water environment and flood management; (3) improved urban lake environment; and (4) project management and capacity building. The project area covers Tianjia’an District, Datong District, Bagongshan District and Xiejiaji District of Huainan Municipality. The overall objective of the Preliminary Project is to improve surface water resources management, flood control capacity and urban water environment, public health and life quality of urban residents in Huainan Municipality.

flood discharge pump stations (with a total lift capacity of 173.7m3/s). To be specific, this component includes the construction of the 13.78km long Gaotang Lake embankment, construction of 4 rainwater pump stations in Gaotang Lake New District (with a flow rate of 22.1m3/s, 38.1m3/s, 6.3 m3/s and 3.0 m3/s, respectively), upgrading Dajianggou pump station (from 6.0 m3/s to 41.0 m3/s, including 6.0m3/s for the reserved capacity and 35.0m3/s for the increased capacity), upgrading Long Lake pump station (from 14.2 m3/s to 48.2m3/s, including 5m3/s for reserved capacity and 43.2m3/s for increased capacity); reconstruction of Shijian Lake Pump Station (to increase the flow rate from 2.6m3/s to 26.0m3/s by removing the existing structure with a capacity of 2.6m3/s and constructing a new pump station with a capacity of 26.0 m3/s).
3 Improved urban Integrated rehabilitation, including dredging, ecological lake environment restoration, and ecological revetment and water purification structures, at the estuaries of the five lakes of Long Lake, Shijian Lake, Dajianggou Lake, Caoling Lake and Gaotang Lake.
4 Project (a) Consulting services provided by independent consultant before management and loan effectiveness, and consulting services provided during project capacity building implementation; (b) all types of training; (c) external resettlement and environmental monitoring services; and (d) office equipment procurement.
2. After the Preliminary Project was put into implementation, adjustments were made by HMG to the Master Plan of Urban Drainage (Rainwater) and Flood Control in Huainan Municipality (Year 2010 – 2020). As a result, the lake embankment and revetment and pump station construction works for Gaotang Lake was cancelled as the proposed location of Gaotang Lake embankment in the Preliminary Project conflicts with the Master Plan. In addition, Due to the adjustment to the Huainan Municipality Master Urban Plan, the proposed installation works of the sewage systems in the eastern parts of Gaotang Lake New District and Binhe New District were cancelled as it does not fit in the scheduled year of development of Binhu New District; the civil works of Longwang Channel was deleted due to LAR difficulties.

3. The generally low bidding for the contracts already procured under the Preliminary Project has resulted in large savings on the project fund. As of December 2016, the total balance fund of the Preliminary Project had amounted to $93 million due to fund savings in the tendering process and cancellation of project components.
4. It is therefore necessary to make adjustments to the project components of Huainan Urban Water Systems Integrated Rehabilitation Project to effectively utilize the ADB loan and assure the realization of the general objectives of the Project.
2. New project components
5. The new components proposed by HMG after discussions include: (1) improved urban sewage collection and delivery system (wastewater collection pipeline network and pump station); (2) improved urban water environment and flood management (channel dredging, slope protection, rainwater lift pump stations and rainwater pipelines); (3) rehabilitation of urban lake ecosystems (dredging and revetment); (4) equipment procurement and capacity building. Due to inclusion of the proposed components, the project area will be expanded to cover Tianjia'an District, Shannan New District, Bagongshan District, Xiejiaji District, Panji District, Huainan Coal Chemical Industry Park, Maoji Experimental Area and Shouxian County.
6. ADB Financed Anhui Huainan Urban Water Systems Integrated Rehabilitation Project Mid-term Adjustment Project (the Project) involves a total investment of CNY 1,365,949,000 and is scheduled to commence in March 2018 and complete in a
7 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment construction stage of 24 months.
B. Project rationale and necessity
7. Affected by decentralized discharge of local wastewater, the surface waters in the areas where the new components to be added are located suffer from deteriorated water quality and fail to meet the water environment function targets for urban waters in Huainan Municipality. In addition, the subproject area is suffering from urban waterlogging and floods with a recurrence period of two years and the urban flood control and flood discharge capacity is seriously insufficient.
8. As the effluent trunk sewers of the old residential communities in Huainan remain disconnected to the regional urban sewerage pipeline network and no sewage pipelines are included in the design of the roads to be constructed in the old urban areas of Tianjia’an District and Xiejiaji District soon, wastewater from these old residential communities will have to be discharged locally. Drainage pipelines already built in the Maoji Experimental Zone are seriously silted and the coverage rate of the drainage pipelines is low. It has been noticed during the construction of the road drainage pipeline network in the early stage that the drainage pipelines of the upper and lower reaches are disconnected. Since the downtown of Huainan Municipality is topographically low in the south and high in the north, Tangshan Sewage Interception Channel, Xinhua Sewage Interception Channel and Kongli Flood Discharge Channel are frequently found flooded in the stormy season in the summer; the water environment function of several river systems in the region is degraded due to serious siltation and water pollution, generating direct impacts on the water environment of Huaihe River Basin.
9. Component No. 1 to be added includes the construction of domestic wastewater pipelines and sewage interception pipelines of the flood discharge channels in the new and old urban areas with a total length of 76.8km and a sewage collection capacity of 6,192,000m3/a domestic sewage in the area to reduce the pollution of local surface water caused by decentralized discharge of domestic sewage in the region. Component No. 2 to be added aims to improve urban flood protection and discharge through the rehabilitation of a total of 18 flood discharge channels with a total length of 60.64km; construction of the 7 flood discharge pump stations will result in an additional flood discharge (drainage) capacity of 45.8m3/s covering a service area of 133.2km2 to significantly improve the flood control and drainage capacity in the project area; Component No. 3, ecosystem restoration, includes lake dredging, sewage interception and ecological restoration in the three corner ponds in the old urban area of Shouxian County to improve the ecological environment of lakes in the region.
10. The design objectives of the new components to be added to the project are fully consistent with those of the Preliminary Project. Upon completion, the flood discharge capacity of the urban channels and the urban sewage collection rate will be increased and the environmental conditions of the urban lakes will be improved, helpful to realizing the

C. EIA preparation
11. The project is classified as ‘Category A’ for environment under the Asian Development Bank (ADB) Safeguard Policy Statement (SPS, 2009), requiring the preparation of a full EIA Report.
12. The references for preparation of the EIA Report mainly include the ADB Safeguard Policy Statement (2009) and the relevant environmental laws and regulations of PRC and the feasibility study report of the Project.
13. The EIA report was approved by Huainan Environmental Protection Bureau on 16 March 2018.

44. No borrow area will be provided during the construction of the Project. The needs of earthwork fill for the Project will be satisfied through reuse of waste soil generated from the Project and by means of filling the depressions using soil excavated from positions of higher elevation. Soil stockpiled in the existing disposal site will be used for the borrow fill of Tangshan Flood Interception Channel while sediments from dredging operations will be stockpiled at such disposal sites. Soil generated from dredging in the various sub-components will be used for slope leveling and topping and planting of the slope vegetation of the respective channels. Dredged sediments with high moisture content will be transported to and dried at the disposal sites before reuse. The sediment disposal sites will be located at the low-lying wasteland along the channels.
Table IV-14 shows the details for disposal sites for the various sub-components under the Project.

C. Anticipated Environmental and Social Benefits
45. Social Benefits.The anticipated benefits of the Project include improved flood control, reduced flood and waterlogging hazards, improved water quality and improved flood control and discharge capacity in the urban center of Huainan Municipality and realization of the flood discharge standard for floods with a recurrence period of 30 years in the urban area of Huainan Municipality.
46. Environmental Benefits.With the status quo of urban sewage pipeline installation and municipal WWTP construction and operation in Huainan Municipality taken into account, the Project will produce significant positive effects upon completion.
47. It is known from an analysis of the monitoring results of the surface water quality in the project area that non-compliance of COD and NH3-N is noticed frequently in the receiving water bodies involved in Subcomponent No. 1. Table IV-15 shows the status quo of water quality and environmental functions as well as the water quality targets of the receiving water bodies involved in the proposed Subcomponent No. 1.

48. Upon the completion of the proposed sub-component 1, the various sub-components will collect and deliver the domestic sewage currently discharged in a decentralized way in the respective regions on a yearly basis to the municipal WWTP for treatment so that the effluent meets Class 1A standard limits specified in the Discharge Standard for Municipal Wastewater Treatment Plants (GB18918-2002). Thanks to the reduction of decentralized discharge of wastewater and pollutants, the water quality of local surface waters will be improved. The reductions of COD, NH3-N and TP in Sub-component 1 are showed in Table IV-16.

49. Results of calculation of the reduction of pollutants in the local water bodies of each subcomponent in Table IV-16 show that the water quality of the surface water bodies in the region will be improved thanks to the construction of Sub-component 1.
50. Interception of domestic sewage is also considered in the design of the channel rehabilitation works. The domestic sewage will be collected and delivered to the WWTP for treatment. Upon the embankment rehabilitation of the ditches, it will be unlikely to directly discharge the runoffs in the farmlands on both sides into the ditches. Therefore, after the Project is implemented, water quality of the project channels will be improved to help realize the water quality targets set in the Water Environment Functional Plan of Huainan Municipality.
51. Ecological Benefits.The rehabilitation of urban ditches will include dredging, box culvert construction, ecological block retaining wall construction, ecological bag slope
53 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment protection, shredded natural vegetation net slope protection and turf slope protection. Thanks to the construction of the Project, the biological diversity of the ecological belt along the river will be restored to enable gradual construction of an ecosystem with benign circulation in the construction area, strengthen the natural purification capacity of the ecological belt along the river in the construction area, and reduce NPS pollutant load using the filtering and interception functions of the biological system in the ecological belt for the purpose of effectively improving inflowing water quality. Garbage and sediments in the polluting runoffs flowing into the river will be intercepted to reduce siltation on riverbeds, build a healthy and vigorous ecological system, improve the ecological landscape along the rivers and improve the environmental conditions in areas on both banks of the rivers.

V. DESCRIPTION OF THE ENVIRONMENTAL CONDITIONS
A. Natural environment
1. Geographic location
52. Located at 116o21’21’’–117o11’59” east longitude and 32o32’45”–33o00”24” north latitude in the northern-central part of Anhui Province, Huainan Municipality is at the middle reaches of and spans across Huaihe River and has a distance of 15km, 58km and 180km respectively 1 from Hefei Municipality, Bengbu Municipality and Fuyang Municipality of the same province.
2. Topography and geology
53. There are two types of landforms in Huainan Municipality with the Huaihe River as the dividing boundary. Areas south of the Huaihe River are low hills belonging to the Jianghuai Low Hills while areas north of the Huaihe River is the flat Huaibei Plain witnessing the uplift and discontinuous low hills extending east-to-west on the south bank of the Huaihe River. Around the hills is a slope belt below which is Grade 2 alluvial terraces interconnected in a staggered pattern. Below the Grade 2 terraces north of Shungeng Mountain is the Grade I alluvial terrace of the Huaihe River, below which are the high-elevation floodplain of the Huaihe River and further below the shallow shoals of the Huaihe River. Below the slope land south of Shungeng Mountain are the Grade 1 and Grade 2 alluvial terraces in Gaotang Lake in the east and the Grade 1 and 2 alluvial terraces in Wabu Lake in the west, with a hilly high-land in the middle. The low-lying plain north of the Huaihe River is higher in the northwest and lower in the southeast.
54. Soil in Huainan mainly comprises of yellow brown soil and paddy soil. The yellow brown soil belongs to the horse liver soil genus evolved from the Late Pleistocene loess-like sediments while the paddy soil belongs to the fertility horse liver soil genus evolved from the mother soil of horse liver soil.

Survey Scope and Sites.The ecological status survey covers the area extending for 300m from the boundary of pipeline construction, river and lake rehabilitation sites in the Project. During the EIA, the EIA Consultant carried out a field investigation to the sites of the project components and collected the data on the status quo of the ecological environment of the various districts in Huainan Municipality. Based on the status quo of ecological environment in the project area and the characteristics of the project construction, 4 representative sampling sites were identified for focused survey, including the corner ponds in the Old Urban Area of Shouxian County, Dingjiagou, Nantang Flood Interception Channel and Wuyi Channel. Survey of the other project affected areas is carried out by means of species recording and the contents of such survey include the types and compositions of terrestrial animals and plants and aquatic organisms.
96. Status quo of vegetation.The project area belongs to the warm-temperate deciduous broad-leaved forest area in terms of vegetation zoning, with deciduous broad-leaved forest as the main vegetation type. It is found during the site survey that artificial vegetation constitutes the main vegetation in the project affected area and trees are distributed in a scattered manner, featuring in relatively simple ecological composition and structure and low level of biodiversity. The trees widely distributed and commonly planted for local landscaping are the main plant species.
i. Terrestrial Vegetation.In this field survey, plants belonging to 23 species of 16 families are identified, including 10 tree species of 8 families, 7 shrub species of 4 families and 6 herb species of 4 families; The dominant tree species are willows (Salix babylonica), poplars (Populus devidiana), wingnuts (Pterocarya stenoptera), locusts (Robinia pseudoacacia) and sycamore (Firmiana simplex); the dominant shrub species are Nandina domestica and Fraxinus chinensis; and the dominant herbaceous species include Imperata cylindrical Var•major, Setaria viridis and Artemisia vulgaris.Aquatic Vegetation.In the field survey, aquatic vegetation belonging to 7 species of 5 families are identified in areas around the rivers and channels. The dominant species are Alternatehera philoxeroides, Nelumbo nucifera Gaertn, Nelumbo nucifera, Phragmites australis and Herba Spirodelae. ii. Aquatic Organisms.Phytoplankton.During this survey, 12 species of phytoplankton under 3 categories are found in the project affected area, with chlorophyta and Bacillariophyta as the main algae species and palella and Oscillatoria the widely distributed dominant species. iii. Zooplankton.There are 6 species of zooplankton, with rotifers being the mostly widely distributed species in lakes, followed by protozoa and cladocerans. Asplanchna priodonta, Brachionus urcens, Cyclopidae are the dominant species. iv. Benthonic organisms.There are 8 species of benthic organisms, including 2 species of annelid, 5 species of mollusks and 1 species of aquatic insects. With a small number of species for the benthic fauna, the dominant species are relatively
112 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
easily identifiable and mainly include Limnodrilus sp., Bellamya purificata and Cipangopaludinachinensis. The aquatic insects mainly comprise of Chironomus plumosus, Limnopernalacustris, Ephemera Ephemera sp. and so on.
97. Terrestrial Animals.A review of available data reveals that there are 15 species of wild animals belonging to 8 families in the project area. With poor diversity, most of the identified animal species are field animals. During this field survey, no large wild animals were found. The mammals in the project affected area are dominated by rodents, mainly including Mus musculus Linnaeus. Fejervarya limnocharis is the dominant species of amphibians.
98. Birds.It is indicated in the "Status Quo Survey Report of Ecological Environment in Huainan Municipality" that the birds in Huainan are mostly summer migrant birds including Cuculus micropterus micropterus Gould, Cuculus canorus camorus Linnaeus, Hirundo rustica hutturalis Scopoli, Hiorundo daurica Japonica Temminck et Schlegel. Therefore, this survey is arranged in the summer, i.e. in the months of August and September in 2017. Birds in the project area belong to 11 species from 11 genera, 9 families and 5 orders. Summer migrant birds, mainly including Cuculus micropterus, micropterus Gould, Cuculus canpo camro linnaeus, Hirundo rustica hutturalis Scorpia, and Hiorundo daurica Japonica Temminck et Schlegel. The main resident birds are Coturnix caturnix japonica Temminck et Schlegel, Streptopelia chinensis chinensis, Passer montanus saturatus Stejneger, etc. while the travelling birds include Vamellus cinereus, Sturnus cineraceus Temminck and so on.During the EIA, small egrets (Egretta garzetta), quails (Coturnix caturnix japonica Temminck et Schlegel), and sparrows (Passer montanus saturatus Stejneger) and other commonly seen birds were observed during the field survey. More than ten small egrets were spotted on the lake island in the northeastern corner pond of Shouxian County. It has been confirmed that small egrets are local perennial habitat birds with no migration phenomenon through reviewing local ecological data, site investigation and consultation with the local forestry bureau.
99. Fish.The project area has a fish fauna composition similar to the Huaihe River. During the survey, 5 fish species belonging to 2 families were identified, with the Cyprinidae being the dominant family. The dominant fish species are Cyprinus carpio and Hypophthalmichthysmolitrix. Hemiculter Leucisclus (Basilewsky) is the most populated small-sized fish.
100. Status quo Assessment of Ecological Environment.Vegetation survey in the project area indicates both excellent growth of vegetation and normal biomass in the region. The widely distributed tree species in the region, e.g. large crown poplar and Italian poplar, grow very well, indicating that Huainan Municipality enjoys an excellent background of ecological environment. Wide distribution of herbaceous plants is observed in the river valleys and lakes in the project area, mostly Compositae and trees. The project area involves neither designated protection areas nor habitat for protected wild animals and plants. In the project area, there are few species and quantities of wild animals and
113 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment rodents are the dominant animals.Arbor trees distributed in a small area in a decentralized way are found in the corner ponds in the old urban area of Shouxian County due to the lasting impacts from human activities. Most of such trees are native species. In the project area, there is no rare, endangered and protected animals and plants. The small egrets found inhabiting the northeast corner pond in Shouxian County are currently identified as common species.
D. Linked facilities
98. The main linked facilities that might affect the realization of the development objectives of the Project are the existing wastewater treatment plants, which might affect the functioning of the sewage pipelines and sewage interception facilities to be constructed under the Project. Therefore, a due diligence has been conducted in this EIA over the four wastewater treatment plants linked to Huainan Municipality.
1. Huainan Municipal WWTP
99. Since the main effluent sewers of the old communities in the urban area of Huainan Municipality remain disconnected to the built sewage pipeline network, wastewater and sewage from these communities have to be discharged locally and the collection rate of the sewage pipelines remains low, not only resulting in the polluted environment, but also hindering the full-load operation of the existing WWTPs. In the meanwhile, no sewage pipelines are included in the design for the time being for the 6 road construction projects commenced recently, such as Dongshan Street and Binguan Road.
100. The volume of domestic sewage discharged from the aforesaid areas is about 1000 m3/d. Such domestic sewage is collected and delivered via the pipelines to Huainan No.1 WWTP of Huainan Shouchuang Water Co., Ltd for treatment.
101. Huainan No.1 WWTP of Huainan Shouchuang Water Co., Ltd belongs to Huainan Shouchuang Water Co., Ltd and is located in Huainan Municipality, Anhui Province. Located on Xiatao Road, Tianjia'an District in Huainan Municipality, Anhui Province, the WWTP has a designed treatment capacity of 100,000 m3. Since put into operation in May 2002, the WWTP has been running in good condition and achieved a treatment capacity of 89,800 m3/d. With oxidation ditch treatment process as the main treatment process, the treated effluent can achieve the Class 1A standard specified in the Pollutant Discharge Standard for Municipal Wastewater Treatment Plants (GB18918-2002).
2. Maoji Experimental Zone WWTP
102. With no sewage pipelines installed, this WWTP already built in Maoji Experimental Zone Remains unable to collect and receive wastewater and, as a result, the wastewater treatment facilities have to stay idle. The main problems found on site include:
103. Xiaji Town: As no sewage pipelines are installed, wastewater in the area is
114 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment effectively collected and discharged into Yingfeng River, which, consequently, is significantly polluted and requiring urgent actions.
104. Maoji Experimental Industrial Park (on the north bank of Yingfeng River): The municipal roads in this area are new roads built in recent years, most of which have sewage pipelines that, however, are neither networked nor connected with the WWTP. As a result, wastewater in the area is not effectively collected and has to flow into Yingfeng River, resulting in serious pollution of the river, and urgent action is required.
105. Downtown Maoji District: The municipal roads in this area are new roads built in recent years, most of which have sewage pipelines that, however, are neither networked nor connected with the WWTP. As a result, wastewater in the area is not effectively collected and has to flow into Yingfeng River via the stormwater pipelines, resulting in serious pollution to local waters that require urgent action of treatment.
106. Other areas (southwest of the intersection between the expressway and County Highway X024, south of the expressway and east of Dingjiagou Village): these developing areas are currently highly populated. Small in amount, the domestic sewage is, however, discharged in a decentralized way, resulting in serious pollution of internal environment. Along with the growth of land development, wastewater discharge is foreseeably growing. Therefore, it is necessary to build a trunk sewage pipelines to deliver wastewater into the WWTP in the town area.
107. The aforesaid areas involve a total sewage capacity of about 10,000 m3/d. the domestic sewage is collected and delivered via the pipelines into Maoji Experimental Zone WWTP for treatment.
108. Maoji Experimental Zone WWTP was built in 2012 and adopts the activated sludge process with denitrification and phosphorus removal functions as the secondary treatment process. With a design capacity of 15,000 m3/d, the WWTP achieves a treatment load of 4000 m3/d at the present stage.
3. Huainan Western WWTP
109. The trunk sewers the under roads in the eastern and western parts of Huainan are substantially constructed. However, the pipelines at the outskirts of the city are not yet networked. In these outskirt areas, there are a large number of highly populated areas that are distributed in a decentralized way, such as the shantytowns, residential areas for migrant rural workers and resettled households. The domestic sewage in these areas is discharged in a concentrated way into and causes significant damages to the water environment in the vicinity.
110. Liyuan New Village drainage facilities to be constructed under the Project is located in Wangfenggang Town and Liyingzi Town in Huainan Municipality. These areas involve a sewage discharge capacity of about 200 m3/d. The domestic sewage is collected and delivered via the pipelines into Huainan Western WWTP for treatment.
115 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
111. Huainan Western WWTP is administered by Huainan Shouchuang Water Co., Ltd and is located at Yangjiadi Village, Bagongshan District of Huainan Municipality, Anhui Province. With a designed treatment capacity of 100,000 m3/d, Huainan Western WWTP was put into operation in August 2008 and the wastewater treatment equipment has been running in good condition since then and achieved a daily average capacity of 72,700 m3/d. Adopting state-of-the-art wastewater treatment equipment, the WWTP uses the oxidation ditch treatment process and the treated effluent reaches Class 1A standard specified in the Pollutant Discharge Standard for Municipal Wastewater Treatment Plant (GB18918-2002).
4. Shouxian County WWTP
112. Domestic sewage from the sewage interception facilities of the East Longyin Lake and the three corner ponds in the Old Urban Area is mainly discharged into Shouxian County WWTP.
113. Shouxian County Wastewater Treatment Plant is located in the northwest corner of Shouxian County and has a designed wastewater treatment capacity of 40,000 tons. Involving a land occupation area of 86.3 mu, Stage 1 WWTP was put into trial operation in June 2009 and passed the acceptance check of environmental protection in July 2009 achieving a treatment capacity of 2 million m3/d; Covering an area of 49.7 mu, Stage II WWTP was completed at the end of August 2012 and approved for trial operation on September 16, 2012, achieving a wastewater treatment capacity of 20,000 m3/d. Shouxian County Wastewater Treatment Plant adopts a new improved oxidation ditch process and mechanical thickening and dewatering process for sludge treatment. With the effluent subject to UV disinfection, this WWTP achieves Class 1A standard specified in the “Emission Standard for Urban Wastewater Treatment Plants”. Influent received by the WWTP is fully domestic sewage and no production and industrial wastewater is involved. Thanks to the efforts of scientific management and standard operation, Shouxian County
WWTP has assured stable and normal operation and COD and NH3-N online equipment are installed at both the inlet and outlet and have passed the inspection by the environmental protection authority. real time interconnection is achieved with the provincial and municipal online platforms. the concentration of oxidation ditch sludge is substantially maintained in the range of 4500-5500 mg/l. The remaining sludge is dewatered mechanically and sent to the county landfill for disposal. The WWTP as a whole is currently in normal and stable operation.
114. Table V-21 shows the wastewater treatment capacity, actual operational load, remaining treatment capacity of the WWTPs that the Project depends on and the receiving capacity of the Project indicated in the survey and calculations.

115. It is known from the due diligence results shown in the above table that the remaining wastewater treatment capacity of Huainan Shouchuang Water Co., Ltd (Huainan) No.1 WWTP, Maoji Experimental Zone WWTP, Huainan Western WWTP and Shouxian County WWTP meets the required and estimated receiving capacity of the sewage pipelines and sewage interception facilities under the Project and no additional actions are required. This means these existing WWTPs will be able to receive the increased wastewater flow and will continue to meet applicable discharge standard by keeping normal operation.

IV. Alternative Analysis
A. Comparative analysis of the “with-project” scenario and “without-project”
scenario
116. A comparative analysis is conducted over the environmental impacts and benefits of the “with-project” and “without-project” scenarios from the perspectives of engineering technology, environmental and social impacts and investment cost. Results of such comparative analysis are shown in detail in Table IV-1.

Conclusion In the "with-project" scenario, short-term adverse social and environmental impacts will be generated in the construction stage, but long-lasting and positive social and environmental impacts will be generated in the operation stage. In conclusion, the “with-project” scenario is better than the “without-project” scenario.
117. It is indicated in the comparative analysis in Table IV-1 that problems of poor urban water system and flood management, decentralized discharge of domestic sewage by the residents and urban waterlogging do exist prior to the construction of the Project. In the with-project scenario, positive social and environmental impacts will be generated in the operation stage of the Project, mainly including fundamental change of pollution to local surface waters thanks to collection of regional domestic sewage currently discharged in a decentralized way, improved urban flood discharge and control and reduced life and property risks brought by urban waterlogging to local residents. However, in the “with-project” scenario, certain environmental impacts will be generated from dust and noise involved in the construction stage of the Project, which, however, are short-term and reversible and may be avoided or minimized through the corresponding mitigation measures. Therefore, this Project is necessary.
B. Comparison of lake eco-revetment alternatives
118. There are five alternatives for comparison in terms of the lake eco-revetment to
119 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment be constructed upon the completion of dredging of Longyin Lake and the three corner ponds in Shouxian County. Details of such comparison are showed in Table IV-2.

Conclusion Based on the above analysis and taking into account the actual situation of the respective rivers and ditches, the following choices are made in terms of revetment construction: 1. Northwest corner pond: Turf slope protection is selected for the gentle slope sections and slope cutting plus eco-bag slope

Southwest corner pond: Turf slope protection is selected for the gentle slope sections and slope cutting plus eco-bag slope protection is selected for the steep slope sections close to non-residential areas while eco-bag slope protection plus grouted rubble retaining wall and pine pile revetment is selected for sections close to residential areas.
C. Comparison of river revetment alternatives
119. Vertical revetment and slope revetment are available for selection for the 19 urban river channels to be rehabilitated in the Project. There are 8 types of vertical retaining walls and 6 types of slope revetments available for comparison. Details of comparison for the vertical retaining walls are shown in Table IV-3 while those for the slope revetment alternatives are shown in Table IV-4.

Result of comparison It can be found through comparison of the above-mentioned vertical ecological revetment alternatives that Alternative (1) and (2) are conventional retaining walls of grouted rubble or concrete allowing no greening of the vertical hard walls and thus generate poor ecological effect. Alternative (4) is the recessed ecological block retaining wall using concrete blocks of big unit weight with excellent wall stability and high construction speed, but involving huge demand for stone materials that may lead to serious damages to local stone mining resources; the grouted rubble retaining wall in Alternative (7) retains the earth taking advantage of the self-weight of the rubbles. The porous structure of such walls allow growing of aquatic plants and realization of natural
122 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
revetment structure. However, similarly, this alternative also involves huge demand for stone and may lead to serious damages to local stone mining resources. Alternatives (3), (5), (6) and (8) have better comprehensive performance than the others and are adaptable to certain deformation and subsidence of the river banks, thus implying less requirements on the carrying capacity and possibility of creating a pleasing ecological landscape thanks to future vegetation growth and coverage. These alternatives have excellent water permeability and filtering functions and allow adequate exchange of water in soil which assures effective retention and timely supplement of water needed for plant growth, thus presenting excellent friendship to plants. Conclusion Based on the above analysis and taking into account the actual situation of the respective rivers and channels, the following choices are made in terms of the slope protection of such rivers and channels: Alternative (2) for the flood discharge channel in the new urban area of Shouxian County, Shanchong Flood Discharge Channel, Nantang Flood Discharge Channel, Qianhuai Flood Discharge Channel, Rushan Reservoir Flood Discharge Channel, Xinhua Flood Discharge Channel, Yangwei Channel, Shannan New District water systems; Alternative (7) for Tangshan Flood Interception Channel, Xinhua Flood Discharge Channel, Kongli Flood Discharge Channel, estuary excavation of Nihe River Pump Station ; Alternative (8) for the flood discharge channel in the new urban area of Shouxian County, Shanchong Flood Discharge Channel, Nantang Flood Discharge Channel, Qianhuai Flood Discharge Channel, Rushan Reservoir Flood Discharge Channel, Xudagou Channel and Shannan New District water systems.

Conclusion Based on the above analysis and taking into account the actual situation of the project rivers and channels, the following choices are mate in terms of the slope protection for each of the rivers and channels: Alternative (1) for the flood discharge channel in the new urban area of Shouxian County and Nantang Flood Discharge Channel; Alternative (3) for Wuyi Channel and Yangwei Channel; Alternative (4) for Kongli Flood Discharge Channel, Qianhuai Flood Discharge Channel, Rushan Reservoir Flood Discharge Channel and Xinhua Flood Discharge Channel’; Alternative (5) for Shanchong Flood Discharge Channel, Nantang Flood Discharge Channel, Tangshan Flood Interception Channel, Xinhua Flood Discharge Channel, Wuyi Channel, Xuda Channel, Maoji Diversion Estuary, Maoji Guangou Channel; Alternative (6) for Shannan New District K Water System and Maoji Yingfeng River.
125 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
D. Comparison of dredging methods
120. Based on the FSR of the Project, 0.5m3 and 1m3 hydraulic backhoe excavators will be used for river channel earthwork excavation and dredging of the subcomponent while enclosed tank trucks or 8t dump trucks used for transportation and removal of sediments and earthwork; for the dredging works of the lakes and three corner ponds in the Old Urban Area of Shouxian County, 1m3 hydraulic backhoe excavator will be selected and enclosed trucks or tank trucks used for removal of sediments.
121. In the engineering design stage, cutter suction dredger is proposed for dredging of the corner ponds. In the operation process, after the dredger is positioned in the dredging area, the winch cable on the front bridge of the dredger is released to slowly drop the fan-shaped cutter into the water to carry out the excavation as designed; the cutter rotates at low speed to cut and excavate the sediments, which are sucked by the centrifugal pumps on the dredger and delivered via the discharge pipeline in a fully enclosed manner to the sludge disposal site. Based on the status quo of corner ponds, the space on site is too small to accommodate the dredgers and sludge disposal site. Therefore, the dredger technology is not feasible. Long-arm excavators are highly flexible and involves small disturbance during construction. In addition, sludge generated from the dredging process can be delivered directly with tankers to the disposal site, requiring no temporary stockpiling yards. Therefore, the long-arm excavator dredging technology is recommended in this EIA.
122. The river channels involved in the Project are substantially channels for flood discharge. Some of them are newly opened ones, for which backhoe excavators may be used to achieve sectioned excavation since the earthwork excavation for these river channels is dry construction. During such excavation, a dike may be preserved in the middle and then removed after all the excavation activities are implemented to save water diversion. for earthwork excavation and dredging of old river channels, backhoe or cable shovel excavators may be used. For some of the old river channels, measures for temporary water system interconnection are needed during construction; the revetment works may be carried out in the low-water season with less precipitation. Construction in the areas below normal water level may be carried out by means of sectioned fill of earth and stone cofferdams.
123. The cofferdams in this Project will be homogeneous earth cofferdams, which will be arranged in the channels upstream and downstream of the station. With a crest width of around 3m, the cofferdams will have a designed slope ratio of 1:3 above and 1:5.0 under the water (natural slope under the water) based on the nature of fill earth. Excavated soil will be used for cofferdam filling during which 8t dump trucks will be used to transport the earth to the filling area and then a 74kW bulldozer will be used for filling operation. earthwork above the water will be compacted by the bulldozer. Cofferdam removal will be carried out with a 1m3 excavator while the earth generated from such removal be transported with 8t dump trucks for revetment backfilling or disposal at the disposal site.
126 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
124. Field survey indicated there is no chemical waste in sediment associated with culvert dredging. Further sampling and analysis should be made prior to dredging activities to ensure the selected disposal approach of the dredged sediment is appropriate. The culvert construction method should be decided based on the types of wastes, length and depth of culvert, the actual conditions on site. If only mud is contained in the culverts, high-pressure suction trucks may be used to pump the mud; if the culvert has heavy deposit of construction wastes and tree branches, such wastes may be artificially cleaned and moved to the culvert gate before further removed with excavators or cranes to the dump trucks for final disposal at the sediment disposal sites. Environmental impact mitigation measures for the sediment disposal site are described in Section VII.
125. In the dredging process of the three corner ponds in Shouxian County, it is necessary to protect the Shouxian Ancient City Walls. Communications and discussions with Shouxian County Culture, Radio and TV Bureau conclude that the suction pump plus hose delivery method involves significant impacts on the ancient city walls and is thus determined as inappropriate.
E. Comparison of pipeline alternatives
126. The Feasibility Study Report of the Project includes no alternatives for comparison for the layout of the sewage pipelines and sewage interception pipelines included in the Project. Therefore, the principle of pipeline layout and pump station siting is analyzed upon this comparative analysis.
1. Design principle of sewage pipelines
127. According to the contents of the "Rehabilitation Plan for Water Systems in the Eastern and Western Parts of the Old Urban Area of Huainan Municipality" (2009-2020), the "Special Plan for the Urban Sewage Engineering of Maoji Experimental Zone in Huainan Municipality", and the "Technical Specifications on Pipe Jacking of Water Supply and Drainage Pipeline Construction Projects” (CECS246-2008), steel reinforced high-density polyethylene (HDPE) spiral pipes shall be used for ≤d600 sewage pipelines while Grade II reinforced concrete pipes shall be used for >d600 sewage pipelines. In the design, the total variation factor of domestic sewage volume shall be considered and calculation shall be conducted using the empirical formula of Kz = 2.7 / Q0.11, where Kz = 1.3 when Q≥1000L/S and Kz = 2.3 when Q <5L/S.
128. The principle to be followed upon selection of trunk sewers in the proposed project is that the implementation feasibility of the trunk sewers is guaranteed since it will be unlikely to realize the function of the other pipelines and assure smooth operation of the integrated pipeline system until the trunk sewers are smoothly implemented.
Maoji Town Sewage Pipelines
127 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
129. In the design, the river banks of Yingfeng River are selected for routing of the trunk pipelines from Xiaji Township to Maoji Town for the following considerations:
i. The route selected in the original plan and design involve construction difficulties. Weiba Road is the route selected in the original plan and design. This route is currently arable land. If only the sewage pipelines are implemented as a part of this Project, conflicts with future road construction works will become inevitable and irreconcilable. ii. It is feasible to regard Yingfeng River as the route of trunk pipelines in this design.Yingfeng River rehabilitation is included in the Project at the same time. Results of site survey indicate that excellent construction conditions are available along the banks of Yingfeng River. If simultaneously implemented with the Yingfeng River rehabilitation works, the trunk pipeline installation works will enjoy construction convenience in addition to savings on land and investment. iii. Routing of pipelines from Xiaji Township to Maoji Town.Pipeline section from Xiaji Township to Jingliu Road: On the north bank of Yingfeng River in this section are scattered woods and village branch pipelines. The pipelines are located within the scope of the Yingfeng River rehabilitation works and thus will enjoy excellent convenience upon construction.
130. Pipeline section from Jingliu Road to Xiangzhang Road: The existing roads on the north bank of Yingfeng River are internal roads of the industrial park along Caifu Avenue. A 10KV high-voltage transmission line currently along the bank will cause spatial conflicts with the layout of the sewage pipelines. The 10 ~ 15m building recess space available south of Yingfeng Road on the southern side of Yingfeng River provides better conditions for pipeline construction. Therefore, if this section of the sewage pipelines is located around 7m south of Yingfeng Road, it will be convenient for not only the pipeline construction, but also the future rehabilitation of Yingfeng Road.
Xiejiaji District
131. Liyuan New Village drainage works is located in Wangfenggang Town and Liyingzi Town of Huainan Municipality. Since no municipal roads and drainage pipes are constructed in the scope of Liyuan New Village, stormwater and sewage pipelines are included in this design for the purpose of addressing the rainwater drainage issues in Liyuan New Village.
132. With a full length of 4197m, the sewage pipeline will start at Liyuan New Village in the east and ends at Liyingzi Town wastewater pump station in the west. The 1778m long rainwater pipeline starts at Liyuan New Village in the east and will be laid in parallel with the sewage pipelines to its end at the existing river. Upon the completion of the Project, the drainage problem in the area of Liyuan New Village will be addressed to well facilitate smooth move-in of the Liyuan New Village residential community. Separate pipelines will
128 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment be installed in parallel with a 2m center line space for separate discharge of rainwater and sewage.
Bagongshan Sewage Interception Pipelines
133. In this Project, riverside sewage interception pipelines will be laid along the riverside green corridors in association with the construction of the four water systems of Kongli Flood Discharge Channel, Qianhuai Flood Discharge Channel, Shanchong Flood Discharge Channel and Nantang Flood Discharge Channel also to be constructed in the Project. In addition, actions of sewage interception will also be taken to the confluence points on both sides. With the sewage from the drainage systems of Kongli, Qianhuai, Shanchong and Nantang Flood Discharge Channels intercepted, a part of the sewage previously discharged into the rivers will be collected and treated and the water pollution problem will be mitigated to a certain extent. The other sewage pipelines will be gradually implemented along with the urban transformation and road construction progress of the Municipality as a whole.
134. It is specified in the "Design Code for Outdoor Sewerage Engineering" (GB50014-2006, 2016) that the adopted interception ratio n0 shall range from 1 to 5. When n0 is too small, mixed sewage will be directly discharged into and result in pollution of the water bodies during surface runoff peak period; if n0 is too large, it will become necessary to increase the size of trunk interception sewers and the WWTP, leading to increased infrastructure investment and operation cost and also affecting influent quality of the WWTP. With the design experiences of neighbor cities as well as the confluence volume, interception scale, total pollutant load, water discharge requirements and self-purification capacity taken into account, n0 = 2 is selected in the project design.
135. If too many upstream interception points are considered in the design, the difficulty of future management will be increased. Therefore, With the simultaneous rehabilitation of the four rivers in Bagongshan District and the key river estuaries as well as the actual conditions on site taken into account, cofferdam interceptor wells, trough interception wells and combined interception wells are selected for interception of the confluence pipelines in the design.
2. Principles of Pump Station Siting and Design
136. The pump stations of the sewage collection and delivery system of the Project are all located in Maoji Experimental Zone, where there is 1 WWTP at present. In order to cover the entire Maoji Experimental Zone, long-distance sewage delivery is inevitable. Four sewage pump stations are included in the Project in order to reduce the excessively large depth of pipelines due to long-distance delivery. The Yingfeng River Sewage Pump Station, as one of these pump stations, is responsible for lifting and delivering sewage from Xiaji Township to Jingyi Road sewage pump station in Maoji Town and then further to the WWTP via secondary lifting.
129 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
i. Design capacity.The design capacity of each pump station is determined based on different sewage capacity indicators selected based on the designed service area and different natures of land use. Here described as follows are the location and capacity of each pump station under the Project.
⚫ Yingfeng River sewage pump station: Located at the northeast corner of the intersection between Jingshi Road and Weiba Road, Yingfeng River sewage pump station will adopt the design of an integrated pump station covering an area of 300m2. With a design capacity of 14,600 t/d, this pump station houses three pumps, 2 in service and 1 backup, and the unit pump flow rate is: Q = 98L/s;
⚫ Jingyi Road sewage pump station: Located at the northeast corner of the intersection between Jingshi Road and Weiba Road, Jingyi Road sewage pump station will adopt the design of a semi-underground pump station covering an area of 300m2. With a design capacity of 18,900 t/d, this pump station houses three pumps, 2 in service and 1 backup, and the unit pump flow rate is: Q = 160L/s.
⚫ Guangou south sewage pump station: Located on the south bank of Guangou Channel, Guangou south sewage pump station will adopt the design of an integrated pump station covering an area of 300m2. With a design capacity of 7,800 t/d, this pump station houses three pumps, 2 in service and 1 backup, and the unit pump flow rate is: Q = 70L/s.
⚫ Dingjiagou east sewage pump station: Located on the east bank of Dingjiagou Channel, Dingjiagou East Sewage Pump Station will adopt the design of an integrated pump station covering an area of 300m2. With a design capacity of 9,000 t/d, this pump station houses three pumps, 2 in service and 1 backup, and the unit pump flow rate is: Q = 80L/s.
ii. Pump Station Type.There are 4 sewage pump stations included in the design. Jingyi Road Sewage Pump Station is located inside Maoji Town which has the problem of short supply of land. The other three pump stations are located in farmland on the banks of existing rivers. In order to minimize farmland occupation and environmental impacts, underground integrated pump station will be selected for all four pump stations to be constructed under the Project. Such pump stations feature in excellent landscaping effect, insignificant land occupation, short construction stage, low construction cost and easy operation and maintenance. With the intake grids and pump body integrated into a 3m dia. shaft under the ground and the automated controller being the only exposed part, such pump stations presents a pleasing appearance and also outstanding land-saving benefit.

VII. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
137. The environmental impacts of the proposed project mainly occur in the construction stage. As the construction activities come to an end, the impacts produced by such construction activities on the local environment will gradually disappear.
A. Analysis of anticipated environmental impacts
1. Construction stage
Water environment
138. Impacts from residual water of disposal sites on water environment.The residual water in the disposal sites mainly comprises of leachate from natural sedimentation of sludge and supernatant of the overflow tank. As the Project involves a large number of disposal sites distributed in a decentralized way, the WWTP sewage pipelines in the areas where most of such disposal sites are located are not yet well developed. It is therefore not realistic to discharge the tail water of the project into the municipal WWTP via the municipal pipelines. Direct discharge of such residual water without collection and treatment will produce adverse impacts on the surrounding water bodies.
139. Impacts of dredging activities on rivers and channels.In the construction process, dredging will disturb the sediments. On top of the interface between the water body and the sediments, there always a layer of semi-suspended and granular silty substances which contain high content of moisture, nutrients and organic matters and are very easily dissolved and re-suspended. In the dredging process, such substances and the sediments will spread and release pollutants to the water body if disturbed and easily cause secondary pollution to the water environment.
140. Construction wastewater.Concrete placement is required during the construction of bridges and culverts in the Project. In the course of concrete placement and cylinder washing, a certain amount of muddy wastewater will be generated and the key pollution factor in such wastewater is SS. Discharge of such wastewater is intermittent and decentralized and produces insignificant impacts on the water environment.Wastewater from vehicle washing on the construction site mainly contains SS and oils, respectively with a concentration of 300mg/L and 20mg/L. Direct discharge of such wastewater will have certain impacts on the water environment.Bagged soil cofferdam is adopted for some parts of the Project and regular discharge of wastewater from cofferdam seepage, cofferdam excavation and
131 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment pit wastewater after rainfall is required. Foundation pit wastewater mainly contains mud and sand in a capacity of up to 2000mg/L.
141. Domestic sewage.Domestic sewage of the construction workers mainly comes from toilets and canteens on site and the main pollutants are COD, BOD5, ammonia nitrogen, etc., with a daily discharge capacity of about 4m3/d. Discharged in a centralized way and small volume but at multiple sites, domestic sewage involved in the Project will produce insignificant impacts on the surrounding surface water environment.
142. Other sewages
⚫ In the process of cofferdam construction and demolition, some silt and soil particles will be spilled into the lakes, producing certain disturbances to the water bodies;
⚫ Pollution caused by fuel oil and engine oil leakage from the construction machinery will increase the water quality factors, such as oils, in the water environment, resulting in degradation of water quality;
⚫ Mud and dust from the water-related construction activities in the rain season will flow along with the rain water into the nearby water bodies and produce adverse impacts.
Air environment
143. Air pollutants from the construction activities mainly include dust (secondary dust from the working surface), exhaust gas from fuel combustion in machinery (including transportation vehicles) and odor from sludge disposal sites.
i. Construction dust.Soil exposed in the air after work surface excavation will be dried in the air and easily raises dust in clear and windy days, producing impacts on ambient air quality in the neighborhood.
Dust formed in the demolition process is mostly dust fall with a granularity of 10um~100um. Cement dust, for example, has a granularity of around 100um. In the construction process, in particular during blasting, a part of the dust will carry heavy electric charge, thus capable of floating in the air for a long time, implying lasting environmental pollution. Due to the concentration of dust around the demolished buildings, such dust becomes a carrier of fugitive dust and toxic gases, producing serious impacts on local ecological environment and residents. In such a harsh environment, people may catch a large number
132 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
of cardiovascular and respiratory diseases. The fast growth of the incidence rate of asthma and bronchitis is a result of dust pollution. Eventually fall into the water bodies, soil and plants caused by dust pollution; these dust contaminants eventually fall into the water bodies and on soil and plants and have a certain impacts on local water, landscaping and soil system
Transportation and loading and unloading of powdery materials will bring TSP pollution to areas along the route. It is indicated in an analogical investigation that the scope of impacts from construction dust is small, generally within a distance of 50m outside the boundary of construction sites and 150m at its leeward. ii. Exhaust gas from construction machinery.Operation of excavators, bulldozers and transportation vehicles in the construction process of the Project will produce exhaust gas from fuel combustion, the main pollutants of
which are SO2, NO2, and so on. The amount of such pollutants is related to the quantity and density, and fuel consumption of construction machinery, as well as the quality of fuels and the condition of and the mechanical equipment. Monitoring results of similar projects indicate that the scope of impacts of the main pollutants contained in the exhaust gas from the excavators is 15m to 18m leeward and the concentration value may reach 0.016mg/m3 to 0.18mg/m3. According to the construction organization design, the Project will use a small number of construction machinery and the emission height is limited. Therefore, the scope of impacts is only limited to the construction sites and an extremely limited space, featuring in small scope and short duration of impacts. Therefore, it is expected that the exhaust gas emitted from construction machinery will have little impacts on the surrounding environment and will not result in remarkable deterioration of ambient air pollution in the project area. iii. Odor from sediment disposal sites.In the process of biochemical decomposition of organic matters contained in the sediments, ammonia, hydrogen sulfide and other odory substances will be generated along with the metabolic process of microorganism and protozoa. Odor mainly occurs in the process of stockpiling and transfer of sediments on the sludge disposal sites. Odor emission is fugitive emission. In this Project, analogical analysis method is used for analysis of the intensity of odor pollution sources. Type analysis of river and lake dredging projects indicates that sediments produce obvious odor along the banks in the process of dredging and excavation. Slight odor is observed at a distance of 30m away where Grade 2 intensity is reached, lower
133 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
than the limit standard for odor intensity (Grad 2.5 to 3.5); No odor is substantially detected at a distance of more than 150m. Odor intensity at a distance of 30m leeward of the sediment disposal site may reach Grade 2 with slight odor. No odor is observed at a distance of more than 150m.
Noise Impacts
144. Noise source analysis. i. Intensity of noise source.The impacts produced by this Project on the sound environment mainly occur in the construction stage, including construction of pipelines and pump stations, dredging of channels and lakes and construction of revetment. Constructional impacts on the sound environment mainly come from the traffic noises generated by the various construction plants and vehicles, including excavators, bulldozers, loaders, power stations and vibrators. Such noises will produce certain impacts on the surrounding area at a noise source intensity of up to 75-93db (A).
134 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment

For calculation of sound source attenuation at Point a:
LA(r)=LA(r0)-20lg(r/r0)
Where:
LA(r) — Sound level A at a place at a distance of r from the sound source, dB (A);
135 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
LA (R0)- Sound level A at the reference location r0, dB (A).
iii. Noise Prediction Results.The construction machinery and equipment are mostly point sources. Noise from such point sources reaches the predicted point through geometrical diffusion and attenuation. Noise impacts in the construction stage are predicted using the point source distance attenuation prediction model to analyze the impacts of noises in the construction stage on the surrounding environment. The calculation results of the noise contribution values of individual construction machines at different distances are shown in Table VII-2.

145. Analysis of construction noise Impacts.
iv. Analysis of noise impacts from pipeline and river channel construction.
With the construction works generally carried out in open air, the Project will involve a large scope of impacts. It is known from the pollution source analysis that the noise sources of construction sites is mainly the various high-noise construction machinery and equipment with a single-unit sound level of generally higher than 75dB (a) and, for some equipment, as high as 95dB (A).The pipeline construction equipment involve continuous change of equipment position and there is fluctuation of the number of equipment in operation at different time periods in the same construction stage, making it difficult in the true sense to predict the noise values at the boundary of all construction sites. Table VII-2 shows that construction noise will have a certain impact on the surrounding
136 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
residents. Noise values at different distances from different construction plants should be calculated with the adverse scenarios taken into account. Such noises will substantially attenuate to 70dB(A) at a distance of more than 50m and 55dB(A) at a distance of more than 280m, meaning that both the daytime (70dB(A)) and nighttime (55dB(A)) noise standards specified in the Emission Standard of Environment Noise for Boundary of Construction Site (GB12523-2011) are satisfied respectively.
No night time construction is involved in the Project. However, the pipelines to be installed along the roads are by large located in urban centers and rural areas and the construction sites are located close to residential areas among other sensitive targets. Some roadside residential buildings are at a distance of more than 10 m from the construction area. Without proper mitigation measures, noise intensity outside the houses of local residents reaches 80dB(A), far much higher than Class 2 standards specified in the “Environmental Quality Standard for Noise”(GB3096-2008).
v. Noise impacts of transportation vehicles
Traffic noise generated by transportation vehicles will have a certain impact on local residents. It can be seen from the forecast results in Table VII-2 that the noise level at a location with a distance of 20m or more than 100m at night from the vehicles meets the noise level (70dB (A) for daytime and 55dB (A) for night time) specified in the Emission Standard of Environmental Noise at the Boundary of Construction Sites (GB12523-2011). vi. Noise Impacts during pump station construction
The new sewage pump stations and flood discharge pump stations to be constructed are mainly located in rural areas. Upon the completion of pump station buildings, sewage pumps will be the only equipment to be installed. The pump station construction involves a relatively small quantity and relatively short time of construction. Jingyi Road sewage pump station is the only new sewage pump station with villages in a distance of 200m, with Sixi Village the closest village located 110m away and the other pumps stations far from the sensitive sites. There are few sensitive sites within a distance of 200m from the flood discharge pump stations. Fanggou Flood Discharge Station has a distance of approximately 90m from the closest village of Dengjiagang; Insulated with buildings and fencing walls, the pump station will produce insignificant noise impacts on areas outside the plant boundary, which will attenuate as the distance increases. The impacts on the surrounding sensitive targets satisfy the
137 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
requirements of the standard. vii. Analysis of impacts of construction noise from lake rehabilitation
Shoubin Community, located approximately 40m away to the east, is the closest residential area from Longyin Lake Rehabilitation Component while Zichenghuayuan Community, 45m away to the southeast, is the closest one from Shouxian Old Urban Area Corner Ponds Rehabilitation Component. It can be seen from the prediction results that the project construction will have certain impacts on the surrounding residents. If no mitigation measures are implemented, the noise intensity outside the window of the residential buildings reaches 70dB (A) or even higher, higher than the Class 2 standard, i.e. 60dB (A) in daytime and 50dB (A) at night, specified in the “Environmental Quality Standard for Noise” (GB3096-2008).
In summary, the Project involves a large scope of noise impacts in the construction stage and the area of impacts is different in different time periods and the noise impacts in a certain time period and a certain area are remarkably temporary. But the impacts produced by the construction of the Project on the surrounding sensitive targets are temporary.
Ecological environment
146. In the construction process of the Project, certain ecological impacts will be generated from the activities of pipeline excavation and backfill, river channel dredging, corner pond dredging treatment and so on. Such impacts are specifically reflected in damages of surface vegetation due to clearing of trees, shrubs and weeds in the area of land occupation and scope of impacts due to pipeline excavation and pump station construction, clearing of shrubs and weeds near the river channels during channel excavation and revetment construction, damages to surface vegetation in the course of site clearing for Longyin Lake, clearing of weeds, swamp vegetation and a small amount of shrubs in the course corner pond rehabilitation in the Old Urban Area of Shouxian County, and the impacts on aquatic environment and wildlife due to corner pond dredging. The areas impacted by the construction activities are mainly those closely located around the construction sites.
147. Impacts on Terrestrial Plants.Artificial and landscaping vegetation takes a major part in the vegetation in the project area and the surrounding areas. With a relatively small area of distribution, the terrestrial vegetation mainly comprises of emergent vegetation such as reeds and cattails, submerged vegetation such as shore grass and floating-leaved vegetation such as lotus root and water chestnuts
138 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment distributed in a scattered way on the river banks. The major impacts produced by the Project on terrestrial vegetation mainly include direct change of the status quo of the vegetation due to artificial disturbances such as rolling during construction, destroy of surface vegetation in parts of the impact areas and, consequently, reduction or disappearance of vegetation and decrease of biomass within a certain range of the pipeline and river channel excavation areas.
148. Impacts on Terrestrial Animals.The construction activities will generate certain impacts on amphibians, reptiles and other terrestrial animals possibly present in the area and such impacts are mainly reflected in the destruction of habitats.
149. It is shown in the survey data that there are few amphibians and reptiles in the project affected area. Therefore, the impacts of construction activities on terrestrial organisms are very limited.
150. Impacts on Aquatic Ecology.Constructional impacts on aquatic habitat and phytoplankton and zooplankton: The river channel and lake rehabilitation works in the Project will result in increased concentration of suspended matters in parts of the water areas in the river channels affecting photosynthesis of aquatic plants and reducing content of dissolved oxygen in water. With the sediments removed, the dredging operations will change the original terrain of the rivers and channels of different depths and may temporarily change the flow rate and flow capacity. The resulting environmental changes will lead to the death of a portion of aerobic plankton, fish, benthic fauna and plankton due to degradation of local environment, affecting the survival and reproduction of aquatic organisms and leading to decrease of the population of aquatic organisms in the rivers during construction.
151. The Project only involves a small area of impacts from the river and channel rehabilitation works and the fish, Zoobenthos and plankton are common species, with no rare and protected fish and no fish spawning grounds, feeding grounds, or wintering grounds involved. The adverse impacts on aquatic organisms during the construction stage are short and reversible. Thanks to the improved water quality of rivers and lakes after the construction activities are completed, the Project will benefit the growth of aquatic organisms and fishes.
152. Impacts on Birds.The usage of habitats will be changed. Available data indicates that there are 11 species of birds in the project area and their main habitats swamps, farmland, ponds and rivers. Relying on these areas, small habitats, such as shallow shoals, are formed. Bird diversity is mainly affected by these habitats. Key factors affecting bird population include food, water, resting places, shelters, nesting and territory requirements.
139 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
153. The activities of birds will be disturbed. Although no wintering ground and stopover areas are involved in the Project, implementation of the Project will have impacts on the habitats of birds. Noise, among other factors, in the construction stage will disturb bird habitats.
154. According to the local data and results of site survey, there is a habitat of small egrets in the northeast corner pond in the old urban area of Shouxian County. Implementation of the Project will have certain impacts on the habitat environment of small egrets. The lake island in the northeast corner pond has road connection with the surrounding residential areas and is thus freely accessible to local residents. The birds inhabiting the lake island are accustomed to the daily activities of residents in the neighborhood. Although small egrets are not in the list of rare and endangered animals and national and local protected animals and the impacts generated by the Project on them are insignificant with environmental protection measures implemented, the impacts to be generated in the construction of the Project on the subsistence of the small egrets remain uncertain at the moment.
155. Impacts of Soil Erosion.Soil and water losses in the construction process are mainly attributed to the surface disturbance and vegetation damages caused by pipeline excavation, river dredging and revetment construction, etc., as well as stockpiling and transportation of construction materials, excavated soil and sediments. Without proper measures, the project area will expect aggravated soil and water losses, which will end up with soil erosion.
Solid wastes
156. Analysis of the environmental impacts of domestic wastes.According to the construction plan, about 50 construction workers will be assigned at each construction site. On the assumption that 0.5kg solid wastes will be generated per person per day, the Project will produce 25kg solid wastes each day in construction stage, which, if not collected in a centralized way, will generate certain impact on the surrounding environment.In addition, the construction sites of some remote water systems do not yet have a well-developed domestic waste collection system in place due to small population and remote location. Inappropriate disposal of domestic wastes on these construction sites will bring some environmental problems. Furthermore, most of the construction sites in this Project are in the vicinity of water bodies, which will be polluted by the various organic pollutants and bacteria carried into such water bodies by the domestic waste. Therefore, serious attention should be paid to the disposal of domestic waste in construction areas.
140 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
157. Analysis of the environmental impacts of waste soil.In the process of pipeline construction, excavated soil in a total volume of 1.666 million m3 will be produced. Apart from 1.626 million m3 to be reused for trench backfill, the remaining 40,000 m3 will become waste soil, direct disposal of which will produce certain impacts on the surrounding environment.
158. Analysis of the environmental impacts of sediments.It is highly possible that spills and leaks of water from the highly moist river sediments will occur if the sediments are immediately transported after dredged. In such a case, adverse impacts will be generated on the water, air and sound environment along the routes.In order to reduce the impacts of dredged sediments on the surrounding environment, disposal sites will be provided under the Project for storage of dredged sediments and such disposal sites should have a capacity meeting the requirements of dredging volume of the Project. The disposal sites will be sited in the vicinity of the dredging area to avoid the inconvenience of long-distance transportation and additional contamination likely to arise in the transportation process. It is known from the monitoring results provided by the environmental monitoring agency of the composition of sediments from the channels to be rehabilitated that the contents of arsenic, boron, volatile phenols, mercury, copper, zinc, cadmium, lead, chromium, nickel, total cyanide, benzopyrene, hexachlorocyclohexane, DDT and general pollutants of pH and petroleum in such sediments meet the Class II standard limits specified in GB15618-1995 "Soil Environmental Quality Standard". Therefore, the dredging sediments are not classified as toxic substance. The design documents during the feasibility study of the Project has taken account of the utilization of sediments. The dredging sediments will be used as backfill for landscaping in the Project and vegetation restoration of the temporarily occupied land parcels. Such sediments may be used directly after gravity concentration and natural drying to reduce the moisture and require no special pretreatment.
159. Sediments from river dredging under the Project are classified as ordinary solid wastes and, therefore, disposal of such sediments will not pollute the soil environment in the disposal sites. The soil in the sediment disposal sites will be covered by the dredged sediment in the construction process, leading to changes to soil usage. The existing waste land and low-lying areas will be reclaimed into dry land, forest land or ecological land. Upon the closure of the disposal site, grass or trees will be planted to speed up natural drying and also effectively eliminate odor from the disposal sites.
160. Other solid wastes.The other solid wastes in the construction stage comprise of construction wastes generated from pump station demolition and
141 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment packaging waste, etc., Such wastes are mostly inorganic matters having no significant direct impacts on water and ambient air quality, but may involve issues of land occupation and secondary pollution. If not timely cleared, impacts will be generated on urban landscape, traffic and ambient air quality.
Social Environment
161. Impacts on resident travel and business activities.The urban sewage pipelines to be constructed in the Project are located in the urban area, mostly on both sides of the roads. Fences erected In the construction process will result in reduced road carriageways and affect local traffic. In addition, transportation of building materials in the construction stage will result in the increase of vehicles on road and result in congestion in some roads in the construction stage and bring inconvenience to local residents. Pipeline construction will affect pedestrians and bring inconvenience to roadside business activities and adverse impacts on shops in terms of reduced customer flow.With a short construction stage, the Project will not involve lasting adverse impacts, which will disappear as the construction activities come to an end.
162. Impact on cultural relics sites.The corner ponds to be dredged and ecologically rehabilitated under the Project are respectively located in the southwest, northwest and northeast corner of the Shouxian Ancient City. As described in the "Master Plan for Protection of Shouchun Ancient City Site" (2006-2020), the protected area of Shouxian Ancient City Walls include the ancient city Walls, city gates, gate towers, moats and the various components of the defense system of Shouxian Ancient City and an inner city ring protection and control zone is formed extending inward for 30m from the bottom of Shouxian Ancient City Wall. The boundary of the construction areas of the northeast and northwest corner ponds are respectively 40m and 38m away from the city wall, therefore outside the protection area of the city walls. According to the Feasibility Study Report of the Project and the construction design program of the southwest corner pond, the shortest distance from the fences around the dredging site of the southwest corner pond to the city wall is 22m and the distance from the corner pond construction activities to the city wall is 35m. Located between the construction fences and the city wall are the berm of Shouchun Ancient City, the inner ring road and the greenbelt along the ring road.
163. It is required in the “Master Plan for Protection of Shouchun City Site (2006-2020) that "no new construction projects shall be permitted inside the city". With ecological rehabilitation as the major content, the corner pond rehabilitation component involves no engineering excavation and facility construction, thus not
142 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment belonging to new construction projects. During the EIA, Huainan Municipal Cultural Relics Protection Bureau issued HuaiWenWu Circular No. [2017] 35 “Opinions of Cultural Relics Protection on the Proposed Site of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment” noting that the proposed site is usable as no important cultural relics are present within the scope of the Project.
164. Mechanical plants to be used in the corner pond dredging works include long-arm excavator and dump trucks and the dredged sediments will be transported to the designated yard outside the city in closed tankers. Spills and leaks of sediments during transportation may adversely affect the inner ring road. Mitigation measures have been considered in design. Long-arm excavator will be used for corner pond dredging with very small vibration and minimal impact on the ancient city wall. Additionally ancient city wall and dredging construction site are separated by existing road, which means vibration impact on the city wall from dredging activities will be insignificant. Site of collection sewer construction is quite far from the ancient city wall and vibration impact on the city wall will be adequately mitigated. Therefore, the impacts by the construction activities of the corner ponds on Shouxian Ancient City Walls will be minimal.
165. Impacts on important social targets.This Project does not cross arterial urban roads, railways, bridges and other important facilities, thus producing no impacts on normal operation of railways and highways.
166. Impacts on tourist destinations.The construction of the Project may have certain impacts on tourist access roads to the scenic spots and the scope of such impacts are only limited in Shouxian Ancient City. The corner ponds rehabilitation works of Shouxian County will affect tourist vehicles and increase road pressure or reduce tourist population due to traffic increase from the participation of construction vehicles. However, this impact is limited and will disappear as the construction activities come to an end since the construction activities of the Project will involve no occupation of the inner ring road of the Ancient City.
2. Analysis of environmental impacts in the operation stage
Water Environment
167. Sewage with environmental impacts in the operation stage mainly includes the domestic sewage from the pump station workers and the residual water from the disposal sites.
143 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
168. Domestic sewage.Most of the pump stations under the Project are unmanned. The sewage generated from flood discharge pump stations and sewage pump stations is mainly domestic sewage generated by the management and maintenance staff. Such domestic sewage is in an extremely small volume and produces no impacts on the surrounding environment.
169. Residual water from disposal sites.Seepage of the dredged urban ditches and ground surface will result in increase of groundwater recharge. The improved surface water quality will be favorable to the restoration and improvement of groundwater.
170. The sediment disposal sites may produce impacts of soil erosion to a certain extent in the rain season.
Air Environment
171. The environmental impacts in the operation stage mainly comprise of
impacts on the air environment generated by odor and exhaust gas, e.g. NH3 and H2S generated from the grid channel, the sewage lift pump station, the effluent wells.
172. The sewage pump station adopts a semi-underground installation pattern and the above-ground structures will be fully enclosed, only allowing discharge of odor from the gaps in the top cover of the submersible pumps, the gaps in the top cover of influent well, and the gas diffusion wellhead and valve well openings of the outlets. Otherwise, no impacts will be generated on the air environment during normal operation.
Noise Impacts
173. The water system rehabilitation under the Project mainly includes river and channel dredging and slope protection and revetment. The eco-system rehabilitation includes rehabilitation of Longyin Lake and the three corner ponds in the Old Urban Area of Shouxian County. There will be no noises sources upon completion and no adverse impacts will be produced on the surrounding acoustic environment. Impacts in the operation stage are mainly from noises generated from the operation of the sewage pump station and the flood discharge pump station.
174. Noise source analysis viii. Noise source intensity of pump stations.In the operation stage of the Project, the sewage pipelines will generate no noise in operation and thus involve no adverse impacts on the sound environment. The key noise source in the

Ecological environment
176. Analysis of impacts on ecosystem integrity
149 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
xii. After the Project is put into operation, the overall performance of the productivity of the aquatic ecosystem will increase.
xiii. Impacts on the stability of natural system. After the Project is put into operation, the aquatic and terrestrial biomass in the ecosystem of the regional water systems will be on a rising tendency and the construction of the Project benefit the stability restoration of the natural system;
xiv. Impact on regional biodiversity. The Longyin Lake Rehabilitation Component includes ecological revetment, aquatic plant, ecological floating island and ecological forest, aiming to create an artificial ecological environment. These efforts will make obvious changes to regional biodiversity and, to a certain extent, enrich the urban biodiversity.
xv. In short, The rising productivity of the natural system in the project affected area after the Project is implemented will be favorable to the stability restoration and development of the natural system, implying that the construction of the Project will promote the integrity of the natural ecosystem in the EIA area.
177. Analysis of impacts on terrestrial ecosystem.After the implementation of the project, vegetation will be restored along ditches, rivers, lakes and banks and new vegetation communities will be formed. The multi-species plant selection and multi-structural green space configuration will not only improve urban greening rate, but also manifest urban biodiversity. In addition, the vegetation community will attract and provide habitats for more small wild animals, such as insects, birds, rodents, frogs, snakes, to enable the formation of a new ecosystem.
178. Analysis of impacts on aquatic ecosystem.Implementation of the Project will not only result in the removal of sediments with extremely high content of organic matters and effective mitigation of the serious pollution to the local water bodies in the project area, but will also significantly improve the water quality of the urban channels through the implementation of the sewage interception works among others and create favorable conditions for restoration of aquatic ecosystem.
xvi. Impacts on submerged plants. Results of domestic research show that light, transparency and light compensation depth are factors limiting the survival of submerged plants. Increased river transparency after sediment dredging will facilitate slow recovery of submerged plants. xvii. Impacts on phytoplankton and zooplankton. Algae have fastest responses to changes of water quality. Along with the improvement of water quality in the
150 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
project area, the species of algae will increase while the overall pattern of zooplankton will remain similar to the present status. xviii. Impacts on benthic animals. The benthic animals in project area, in a relatively small population, have been substantially destroyed due to the impacts of dredging operations. Upon the completion of the Project, the habitats of benthic animals will recover gradually. Mosquito larvae and water earthworms will first appear, but molluscs will not appear in the short term. As the water quality further improves and the large plants gradually recover, gradual growth of molluscs population will become likely.
xix. Impacts on fishes. Removal of sediments will be beneficial to the survival of fish, but no significant changes can be expected in the short term to the species and population of fish. In the long run, along with the gradual recovery of phytoplankton and zooplankton, the potential for bait will increase to benefit the growth of fish such as silver carp and crucian carp.
179. On the whole, along with the greening and water quality improvement along river channels as well as the overall improvement of aquatic ecological environment, the aquatic animals and plants will become richer in biodiversity and better in stability than before to benefit the stability of water ecological structure.
Analysis of solid waste impacts in the operation stage
180. Solid wastes in the operation stage mainly include domestic garbage produced by staff, residues from grid operation and remains of dead aquatic plants involved in the removal of artificial wetlands, artificial floating bed, artificial aquatic weeds and pond rehabilitation and other construction activities.
181. After the Project is put into operation, the pump station will have fixed staffing of 2 to 3 workers and very little domestic garbage will be produced, thus having no environmental impact on the surrounding residents.
182. Grid residues of a certain volume will be produced from the coarse grids installed in the pump stations, mainly comprising of solid suspended matters intercepted from the water such as leaves, weeds, plastics, etc., with an annual capacity of 15t per pump station (with a moisture content of about 70%). The remains of aquatic plants, although containing no toxic and hazardous substances, will have adverse impacts on the water environment and landscape if not subject to controlled disposal.
Analysis of environmental risks
151 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
183. The Project does not involve any toxic, hazardous and flammable and explosive substances, except that acetylene welding in the construction stage may lead to fires, explosions and pipe fractures and congestions, which, according to the Technical Guidelines on Environmental Risk Assessment of Construction Projects (HJ/T169-2004) and the Interim Provisions on the Supervision and Administration of Major Hazardous Chemicals Sources, do not constitute significant sources of hazards, thus requiring no environmental risk assessment under the Project.
B. Mitigation measures for environmental impacts
1. Environmental impact mitigation measures for the design stage
Water environment
184. The design institutes shall optimize the preliminary design and construction drawing design following such a principle that “pollution prevention measures are well integrated with, but play a more dominant role than the management tools” so as to minimize the adverse impacts from the construction of the Project on local natural environment and social environment.
xx. Based on the results of the construction organization design in the next stage, the engineering measures to be taken in the land occupation area should be further refined and construction camps should be avoided where possible;
xxi. Location of construction sites is well considered in the design to discharge the domestic sewage generated from these sites into the municipal sewer network and avoid temporary occupation of land outside the scope of permanent land occupation for road construction works. xxii. A reasonable ground slope should be used in the design. A slope of no less than 0.2% should be used towards the direction of the drainage ditches. xxiii. Sewer pipes with high corrosion resistance and infiltration resistance should be adopted with anti-corrosion coating applied inside the pipes. xxiv. The potential impacts on local residents are adequately considered in the layout design of the sewer network. Pipeline installation measures for pipelines located far away from concentrated residential areas are taken. xxv. The potential impacts on downstream water bodies are considered in the design of dredging methods. Relevant measures are designed to mitigate the impact on downstream water bodies;
152 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
xxvi. Dredging method and dredging equipment as selected should be able to achieve minimization of dredging overflow; xxvii. Location design of sediment disposal sites is reasonable and has taken into consideration treatment of leaching water, supernatant from strong precipitation and surface runoffs to minimize the impact of residual water from the disposal sites on the surrounding environment.

192. Sound insulation structures are adopted in the design of the pump stations. Sound insulation and noise reduction materials are selected for walls and the opening rate should be reduced for the equipment rooms. In addition, double-glazed insulation windows are adopted.
153 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
Ecological environment
193. The topographical features of the construction sites are already considered in the design of temporary drainage facilities. Extensive excavation and filling should be banned and intercepting and drainage ditches are included in the design; preservation of existing trees is already considered in the design process.
194. Local vegetation species are selected in the design to avoid the introduction of invasive alien species where possible;
195. Ecologically sensitive sites are avoided in site selection; low-noise sediment suction pumps are selected for the corner pond dredging to maintain the existing habitat for birds in the northeast corner pond and preserve the natural status and flow regime of the corner ponds to avoid drying out.
Solid waste
196. Residential areas are avoided in the selection of dredged sediment disposal sites and low-lying wasteland should be used; sediment disposal sites are not allowed within the ancient city walls;
197. Vegetation greening for site closure is considered in the design; retaining walls are designed around the sediment disposal sites to prevent sediment overflow or spillage.
2. Environmental impact mitigation measures for the construction stage
Water environment
198. Construction camps located in rural areas are reasonably arranged so that existing villagers' houses are rented and used and domestic sewage is pretreated in septic tanks before used as farmland fertilizer. For construction camps located in a concentrated way, underground sewage treatment facilities are provided for treatment of sewage before discharge, with drainage ditches and sedimentation tanks arranged along the sites.
199. Construction materials on the stockpiling sites are covered; Geotextile containment is provided during rain storms to prevent the construction materials from being carried away in runoffs.
200. Cleansing wastewater for construction machinery is used for site watering after oil separation and sedimentation treatment; the foundation pit wastewater is
154 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment treated with secondary sedimentation and then used in construction activities or sprayed on road surface;
201. For pipe network construction works located in the urban area, the construction teams should use the public toilets in the neighborhood; if necessary, the domestic sewage generated should be pretreated with the septic tank and then be discharged to the municipal wastewater treatment plant for further treatment through the sewer network;
202. Slurry from pipe jacking should be collected and the supernatant from sedimentation should be used for water spraying on the construction site for dust suppression. The sediments should then be sent together with the waste soil t to designated disposal sites for disposal.
203. Wastewater produced from water tightness test for pipelines contains a small amount of sludge and is used as supplementary water for slurry that will be used in the construction sections.
204. Temporary cofferdam and dry dredging method will be used and this construction method will ensure turbidity increase will be very limited during dredging. Additionally regular and continuous water quality mointoring of the river section will be done during dredging. The dredged sediment will be hauled to disposal site with retaining structure and measures will be taken for control of discharge quality to prevent turbidity increase of the receiving water body. Measures such as optimizing the design of the disposal sites and extending the retention time of residual water in the disposal sites should be adopted;
205. The water quality at the discharge outlet of the sedimentation tanks should be regularly monitored. If the effluent quality is found not complying with the relevant discharge standard, flocculants should be added immediately and the retention time for settling of residual water should be increased to ensure the effluent quality.
Ambient air
206. Construction dust.Centralized material disposal sites located away from special sensitive sites should be established. Covering facilities should be provided for dust-prone materials. Water spraying facilities should be installed for dust suppression. Water spraying regulations should be developed to have special personnel designated for water spraying and site cleaning. The water spraying frequency should be adjusted based on weather conditions. Vehicle washing facilities should be installed at the exit of construction sites to avoid mud being carried by
155 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
vehicles onto the public roads.
207. A reasonable demolition sequence should be planned. For the demolition of cluster buildings, a feasible demolition plan should be developed and reasonable demolition sequence determined based on wind direction and surrounding environment. Before the demolition commences, the dust on the inside and outside walls and on the floors should be removed with water. Fences with a height of no less than 3m should be installed on the boundary of the construction sites for building demolition, with the fence height designed and calculated based on the geotechnical conditions, meteorological conditions and fence materials. Fences along the key urban road sections should not be less than 3.0 m.
208. Construction materials should be placed under sheds when possible and covered with tarpaulins when stored outdoors. Powdery building materials such as cement and lime should be transported with tanker trucks. The powdery material disposal sites should be located as far away as possible from the centralized residential areas. Overload is forbidden as it may lead to secondary pollution along the transportation routes. Construction schedule should be reasonably planned. Construction on strong windy days is banned.
209. Emission from construction machineries.Quality fuel should be used for transportation vehicles and fuel-powered construction machines. It is strictly forbidden to use fuel of poor quality. At the same time, the transportation routes should be reasonably arranged to maintain the vehicle speed and to reduce idle time. Maintenance of machinery and equipment should be strengthened to make sure they are operated in good conditions. Exhaust purifiers should be installed on the fuel machine to make sure that the exhaust gas meets relevant discharge standards.
210. Dredging sediments disposal site should be located away from residential areas.
Construction noises
211. The impacts on the acoustic environment from the Project mainly occur in the construction stage. In order to minimize the noise impact of construction machinery, the following measures will be taken during the construction stage. xxviii. Noise mitigation measures proposed in the design stage should be strictly implemented;
xxix. A reasonable layout design should be developed for the construction sites to avoid concentration of a large number of powered machineries at the same
156 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
site; fixed machineries should be placed in operation rooms and vibration damping foundation and sound insulation cover should be used for equipment meeting the respective requirements.
xxx. A reasonable construction schedule should be developed to avoid noise producing construction activities in night time (22:00PM – 6:00AM) and noon time (12:00AM-14:00PM). Information boards should be erected on construction sites to inform local residents of construction time and duration; if night shift construction is necessary, prior approval from local environmental protection authorities should be acquired before such construction activities are conducted on the designated date.
xxxi. For construction activities near residential areas, temporary noise barriers or soundproof fences with a height of at least 2m should be erected around the construction sites. The transportation routes for materials, earth and construction waste should avoid concentrated residential areas. Vehicles should reduce speed when entering and exiting the sites or near residential areas (less than 10 km/h). Honking is strictly forbidden. xxxii. For construction activities near schools, soundproof fences with a height of at least 3m should be erected around the construction sites for enclosed construction. Contractors should designate special management personnel and work with the schools to develop a reasonable time schedule for the construction activities avoiding the class time. High noise construction activities should be arranged at weekends or after school hours. No construction is allowed during school examinations. xxxiii. For special construction sections requiring continuous construction at night, coordination with the surrounding areas should be well conducted. After the relevant application procedures are fulfilled and approval is obtained from the relevant agencies, information should be disclosed to the various units in the surrounding areas to obtain their consent before construction activities proceed. xxxiv. During the construction stage, the EA should entrust a qualified agency to monitor the quality of the acoustic environment at the construction sites. Once any non-compliance is identified, the construction activities should be suspended immediately. After the construction intensity and method are adjusted, a secondary noise level monitoring should be conducted and the construction activities should not be resumed until the monitoring results comply with relevant standards.
157 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
xxxv. Artificial noises such as noises of collision during removal of baffles and brackets and loading and unloading of materials / earth should be minimized. Equipment not in use should be shut down immediately.
xxxvi. No concrete mixers should be allowed on the construction sites and commercial concrete should be purchased instead.
xxxvii. Contractors should regularly provide training for on-site staff and designate special personnel to be responsible for the maintenance of the construction machinery to make sure that vehicles are in good conditions and run normally without loose parts or brake squeaks. xxxviii. Personal noise protection measures should be implemented. For workers near high-noise equipment, the working hours should be reasonably scheduled and personal protective devices such as ear plugs, anti-noise helmets should be provided.
Ecological environment
212. Construction shall be strictly limited within the designated construction area. No construction activities are allowed outside the red lines. Temporary land use such as construction camps and material disposal sites should consider the use of unused lands;
213. Construction schedule and progress should be reasonably arranged to reduce the construction time and avoid the rainy seasons where possible.
214. A construction method allowing synchronous excavation and backfill should be used for construction of the sewage pipelines; the river embankment and revetment construction should be carried out on a section-by-section basis allowing synchronization of construction and landscaping; surfaces where the construction works are completed should be compacted and vegetated in time.
215. Top soils and vegetation should be protected. Before the excavation for sewer pipelines installation, the 0-20 cm thick fertile top soil should be peeled off and stored in a protected manner; the existing trees should be relocated and then used for land reclamation and river bank eco-restoration after the construction works are completed.
216. Greater efforts of education and training should be made to raise the environmental awareness of the construction workers. The construction workers are forbidden to destroy any vegetation outside the right-of-way of the Project and hunt
158 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment any wild animals or destroy their habitats.
217. Vegetation restoration measures should be implemented during the construction stage. For the sediments disposal sites and temporary earthwork stockpiling sites, the land surface should be timely cleaned and covered with top soil. Vegetation restoration or land reclamation measures should also be implemented to the exposed land caused by the sediment disposal site,. The temporary construction sites and temporary access roads should also be restored to their original state by the contractors through reclamation or vegetation restoration. Upon the completion of the When pipeline construction is completed, the land should also be timely covered and restored. For other temporary use, the lands should also be timely cleaned up and their original functions restored.
218. Protection measures for aquatic animals and plants should be strengthened in the construction stage. Construction schedule and progress should be reasonably arranged; construction activities should be arranged in dry season where possible to avoid the growth and reproduction period of the aquatic animals and plants and minimize construction disturbances;
219. Upon the completion of the construction works, the aquatic ecosystem should be restored by timely adding different kinds of aquatic organisms into the river. Priority should be given to the freshwater aquatic organisms that are common in the region, such as fishes and shrimps, submerged plants, and mussels; different aquatic communities should be developed based on different habitats. For example, submerged algae plant, mussels, snails, loach, and yellow eel, should be added to the riverbed to improve the stability of and restore the aquatic ecosystems;
220. Soil erosion control measures should be implemented during the construction stage. Structural drainage measures should be given the priority while vegetation measures as the supplementary measures. For temporary construction sites, a combination of land rehabilitation, reclamation and planting should be used; prior to construction, intercepting ditches and drainage ditches and other drainage facilities should be installed reasonably; the stability of cut/fill slopes should be strengthened by installing temporary retaining facility; upon the completion of the Project, the contractor should removal all temporary pavement or buildings and transport the demolished waste to designated disposal sites, with the temporary land occupation areas leveled, restored and landscaped immediately.
Solid waste
221. Garbage bins should be placed on construction sites and construction camps
159 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment to collect domestic garbage;
222. Construction waste generated from the demolition of the existing pump stations should be transported to the designated construction waste disposal site;
223. Contractors should fulfill the relevant procedures and complete the paper works for disposal of sediments and waste soil at designated sites;
224. Vehicles transporting loose materials and waste should be enclosed, packed and covered to avoid spillage along the routes. Earthwork transportation vehicles should operate according to designated time schedule and along designated routes;
225. Dredged sediments should be removed in a timely manner and transported with special tankers to avoid spillage along the routes.
226. Construction sites should be restored in a timely manner after the construction is completed;
227. The dredged sediments with high water content are not easily reusable and should be temporarily stored at designated sites. It is known from the sediment analysis and monitoring report provided by the environmental monitoring institute that the dredged sediments under the Project meet the Class II standard of the Soil Environment Quality Standards and, therefore, may be used as soil after dewatering.
228. The waste soil produced from dredging should be temporarily stored on both sides of the ditches or channels and directly used for land preparation and greening for the embankment;
229. Selection for sediment disposal sites should follow the following principles: such sites should be located far away from sensitive sites including residential areas, but as close as possible to the dredging area to avoid long distance transportation that might lead to inconvenience and pollution during transportation. The bottom lining of the disposal site should be clay layer with poor infiltration where possible.
230. The area and location of the disposal sites in the sub-component areas were determined under the guidance of the local governments based on the results of field survey and investigations. Under the Project, 24 new sediment disposal sites are arranged and 1 existing disposal site is utilized in Shannan New District, bringing the total land occupation area of the disposal sites to 76.76hm2. The land parcels where the disposal sites are located are currently waste lands or low-lying lands and will in the end be rehabilitated into dry land, forest land or ecological land upon the end of the service life of the disposal sites The locations of these disposal sites are shown in Table VII-8.
160 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
231. In order to prevent impacts on regional environment, it is necessary to take water and soil conservation measures to the sediment disposal sites. The structural measures and vegetation measures should play a dominant role while the temporary ones a supplementary role. The structural measures include top soil removal prior to the mobilization of the disposal sites, with the top soil placed on top of the site surface. The vegetation measures include grass and shrubbery planting on the slope of the disposal sites. Mixed seeds of Bermudagrass and Amorpha fruticosa should be planted with a seeding rate of 80kg/hm2 in late spring, summer and autumn. The seeds should be soaked in time to allow full contact of soil and seeds. The total area of plant protection is 44418m2 and grass seeds in a total amount of 355.34kg are needed. Temporary measures include trapezoidal drainage ditch arranged based on the layout of the disposal site with a depth of 40cm, a top width of 120cm, a bottom width of 40cm and a slope of 1:1; the excavated topsoil of the disposal sites are stockpiled on the backwater side around the cofferdams of the disposal sites. The stripped top soil should be protected with bagged soil and covered with fine mesh on the top.
232. An independent rainwater diversion and drainage system should be provided around the sediment disposal sites to reduce the volume of residual water of sediments. Flood interception ditches should be provided on the sediment disposal sites to intercept and collect the rainwater into the catchment tanks before discharge into the local drainage ditches after sedimentation.

169 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
project area are suitable habitats and feeding grounds for birds. The lake island in the corner ponds is not the only habitat for the Little White Egret. However, as a long-term habitat for birds including the Little White Egret, it should be preserved in its current state. The design institute has confirmed that the lake island is not involved in the construction of the Project and the natural landform and vegetation on the island will be reserved; xlix. Construction workers should not be allowed to randomly land on the lake island inhabited by birds. Behavior management should be strengthened for construction workers to reduce disturbance to birds;

170 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment lvii. Vehicles for sediment transportation should strictly follow the routes and time schedule specified by the Shouxian County Traffic Management Department.
3. Environmental impact mitigation measures in the operation stage
Water environment
236. Domestic sewage produced by the staff of the flood discharge pump stations and sewage pump stations should be treated with septic tanks before used for landscaping at the pump station sites. Therefore there will be no sewage discharge to the environment. The domestic sewage produced by staff of the sewage pump stations should be discharged directly to the sewer network and transferred to the wastewater treatment plant;
237. Management of rivers and lakes should be strengthened; fish farming in lakes and rivers should be forbidden; residues of wetland vegetation should be removed in a timely manner along with garbage and debris on water surfaces to minimize their impacts on lake water quality.
Ambient air
238. Stockpiling of grid residues on the ground surface is prohibited;
239. Vegetation and greening around the pump stations should be strengthened;
240. The sewage pump station staff should conduct regular inspection of the air-tightness of doors, windows and covers and deodorants should be sprayed to reduce the emission of odorous gases.
Noise
241. Noise reduction measures have been considered during the design stage to reduce noise impact. Therefore, the main task in the operation stage is to assure the implementation of these measures proposed in the design stage. The specific measures include: lviii. Noise mitigation measures proposed in the design stage should be strictly implemented;
lix. Regular maintenance and repair of pumps and electrical equipment should be strengthened;
lx. Sound insulation cover for equipment such as motors should be installed;
lxi. Areas around the pump stations should be greened and measures such as noise absorption via greening and noise insulation via fences should be taken to contain noise.
171 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
Solid waste
242. An extremely amount of grid residue will be generated from the sewage pump station and will be transported by the local environmental sanitation authority on a regular basis.
243. Garbage and plant debris collected from the water surface in the lakes, reservoirs and rivers should be drained at the collection sites and then delivered to the environmental sanitation department for removal. Random disposal of such solid wastes in the surrounding area is not allowed.
244. Sufficient number of garbage bins should be provided along the river banks. Such garbage bins should be designed and configured in harmony with the local environment to the best possibility.
245. Environmental protection signs should be erected to increase the awareness of environmental protection of local residents and pedestrians.
C. Cumulative impacts
246. It is required in the Technical Guidelines for Cumulative Impact Assessment (CIA) 1 , a cumulative impact analysis is required for the Project. The most significant environmental impact of this Project is improved flood control and drainage capacity and reduced flood and inundation disasters in the main urban area of Huainan Municipality, which aims to achieve the flood discharge standard for floods with a recurrence period of 30 years. Therefore, with the characteristics of the Project and the availability of basic data taken into account, the focus of this CIA is the increased flood control capacity and the assessment period is mainly the operation stage of the Project.
247. Related actions and goals of Huainan Municipality.Huainan Municipality has an average annual precipitation of 893 mm, which, although not large in volume, is relatively concentrated. Due to limited drainage capacity in the main urban area, waterlogging and inundation problems are severe in rain season. Over the recent years, a number of channel rehabilitation and dredging projects and drainage pipeline network construction projects have been implemented in Huainan Municipality, including the implemented ADB/WB loan projects and this Project. One of the goals of these projects is to improve the urban drainage capacity, reduce flooding and inundation and improve the urban flood control standards of Huainan Municipality.
248. The Huainan Urban Drainage (Rainwater) Flood Control Comprehensive Plan (2010-2020) approved in 2015 set the goal for Year 2020, i.e. to improve the flood control standard to 30-year recurrence period. The detailed objects are: no waterlogging will occur in the urban areas during rain storms and the depth of water impoundment on urban
1 Implemented according to the guidance of the Cumulative Environmental Assessment (CEA) issued by the International Finance Corporation (IFC).
172 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
roads should not exceed 15cm; the impoundment duration should not exceed 1 hour; and the length of single impoundment (in the road direction) should not exceed 50 meters.
249. In order to achieve this goal, Huainan Municipality has planned a number of urban drainage pump stations, urban rivers (ditches) and drainage pipe network construction and rehabilitation projects to be completed by 2020 to improve the flood control standard from 10-year recurrence period to 30-year recurrence period. lxii. Flood discharge capacity analysis for this Project.The improved drainage capacity brought by this Project mainly comes from the drainage pump stations and urban river channels (ditches) to be constructed and rehabilitated under the Project. Since the percentages and contribution rates of pump stations can be directly quantified, this flood discharge capacity analysis will focus on the quantified analysis of pump stations. According to the engineering design, 6 flood discharge pump stations will be constructed to serve the urban areas with total capacity of 45.8 m3/s and a total service area of 133.2 km2. lxiii. Expected goal for flood discharge capacity.According to the plan of Huainan Municipal Government, at least 32 urban drainage pump stations will be constructed in Huainan Municipality to realize the goal of promoting the flood control standard to floods with a 30-year recurrence period and achieving a total flood discharge (drainage) capacity of no less than 462.2 m3/s and a total service area of 236.3 km2 by Year 2020. lxiv. All the pump stations already or being constructed in Huainan Municipality and to be constructed under the Project aim to realize the flood discharge standard for floods with a 30-year recurrence period. lxv. Cumulative environmental impact.The construction and operation of the pump stations in the Project will result in increased urban flood discharge capacity of Huainan Municipality. Apparently, such incremental capacity, as part of the total capacity that Huainan Municipality has to have to achieve its goal (of bringing the flood control standard to floods with a 30-year recurrence period by 2020), will have direct cumulative impacts. This Project will realize the construction of 6 new pump stations with a total flood discharge (drainage) capacity of 210.1m3/s and a total service area of 45.8km2, accounting for 19.4%, 45.5%, and 19.4% of the anticipated targets of pump stations, total flood discharge (drainage) capacity and drainage service area, respectively. See Table VII-9 for more details.
173 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment

250. It is known from the above analysis that significant positive cumulative environment impacts will be generated on promotion of the urban drainage standard of Huainan Municipality from the realization of the construction objectives of the Project. Therefore, it is necessary to facilitate the construction and operation of the Project as planned.
D. Climate change and greenhouse gas (GHG) emission
251. Climate change.One of the key components of the Project is to improve the flood discharge capacity of urban waterways and improve the adaptability of Huainan Municipality to flood and waterlogging risks.
252. Huainan is located in the warm-temperate and semi-humid monsoon climate zone featuring in four distinct seasons, mild climate, concentrated rainfall, abundant sunshine, long sunshine hours, large temperature variations, and long frost-free period. With the distinctive characteristics of monsoon climate, Huainan Municipality has hot and rainy summers, cold winter and dry autumn. However, as airstreams from the north and the south converge in this region, precipitations in Huainan Municipality have large yearly variations and uneven yearly distribution.
253. In the context of global warming, extreme weather conditions may cause increased rainfall in local areas, resulting in water level higher than the expected peak water level in the river. The average annual precipitation in the Huaihe River Basin is 942 mm. However the inter-annual variation and the yearly variation are both very large, with a maximum annual precipitation of 1414 mm in 1991 and a minimum one of 391 mm in 1978, representing a variation ratio of up to 3.6. Precipitation in the flood season of June to September accounts for 60% of the total precipitation in a year, with that in July alone taking a percentage of 21% of the yearly total. The yearly average runoff depth is 220mm in the region with a runoff coefficient of 0.23. The yearly average evaporation is 970mm. The yearly average temperature is 14.8°C and the highest monthly average temperature
174 Environmental Assessment Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment is around 28°C. The highest temperature and the lowest temperature are respectively 41°C and -20.0°C. The annual average frost-free period is 230 days. The dominant wind direction in the area is east wind, with northeast wind in most winters and southeast wind in most summers. The occurrence time and frequency of yearly maximum flow in the Huaihe River is largely consistent with the distribution of the average annual rainfall. Precipitation is concentrated in the months of June to September and the yearly maximum flow also occurs mainly in the same four months from June to September and the occurrence frequency accounts for 85.2% of historical floods, with 40% for July.
254. Sensitivity analysis conducted in the preparation stage of the Project suggests that an increase of 15% in peak precipitation will result a 4.45% flow increase and 2.2% water level increase for rivers and channels in the Project.
255. A model analysis conducted in the PPTA stage suggests that the yearly average temperature in Huainan is expected to increase by 2.1 °C, and the yearly average precipitation is expected to increase by 4%. The hydraulic model study from the Design Institute indicated that the flow rate of rivers and channels will decrease due to increase of evaporation caused by rise of temperature. The high-temperature evaporation will offset the impacts from increase of rainfall.
256. Nonetheless, for the urban channels under this Project, it is still necessary to consider the impact of extreme climatic conditions on the water level during the detailed design stage, especially when there are bridges and other important hydraulic facilities along the waterway. Under this project, the design of channel bridges and drainage culverts should take into account the extreme precipitation conditions in Huainan.
257. The design flood was calculated using design storm precipitation data. Based on the characteristics of storms and floods in the watershed, the peak control of design flood will be conducted based on the maximum 24-hour storm precipitation and the design flood will be calculated according to the calculation method included in the “Calculation methods for the contour map of heavy rain, the runoff analysis results in mountainous areas and design flood calculation in small and medium-sized mountainous areas in Anhui Province”.

Yearly 132.4 0.52 3.5 328.9 295.6 268.9 223.0 maximum 3d
258. According to the Flood Control and Drainage Plan of Huainan Municipality, the recurrence period specified in the urban flood control standards of the various counties and districts is 20 years. In Huainan Municipality, the urban area and bridges are respectively designed based on the 30-year and 50-year recurrence periods. Therefore, the design of bridges and drainage culverts of the flood discharge channels under the Project has taken account of the worst scenarios of extreme precipitation in Huainan Municipality and thus meet the needs of flood control and discharge.
259. GHG emission.GHG emission estimation is required in the ADB Safeguard Policy Statement (2009) for projects likely to exceed the yearly threshold of 100,000 tons of carbon dioxide. Based on the estimation during the PPTA stage, GHG emission in the construction stage (including vehicles, machineries, and workers for a period of 3 years) and the operation stage (including power consumption in the pump stations, vehicles emission for a period of 10 years) of the Project (including the newly added subcomponents) is far less than the threshold value of GHG emission with significant impacts as defined by ADB.
260. The main GHG emission process of the Project is the process where the collected domestic sewage after the Project is completed is delivered to the municipal
WWTP for treatment and a small volume of CH4 will be emitted in the treatment process. According to information presented in previous sections of this report, the project will collect 6.192 million m3/year of sewage. The COD reduction for the Project will be 1548 t/a.
Assuming the CO2 emission coefficient is 0.25 kg-CH4/kg-COD and the GWP value is 25 kg CO2/kg (IPCC 4th review, 2007), the GHG emissions will be 2877t/aCO2 equivalent.
261. According to the ADB Safeguard Policy Statement, the GHG emissions generated from treatment of collected sewage in the Project is relatively small. Therefore, no detailed estimation of GHG emission is needed and no consideration will be given to the GHG impacts and their mitigation measures.

273. As a water environment management project with integrated benefits, the Project will not only generate flood control benefits, but will also improve the water environment and tourism development. In order to assure normal operation of the project facilities and realize the full benefits of the Project, it is necessary to establish sound project management rules and regulations for the purpose of carrying out the management work in an institutionalized and standardized way.
274. Management regulations for flood control and discharge.Rules and regulations on flood control and rescue and supply and management for flood control materials and detailed rules on river embankment management integrating professional management and public management will be developed in accordance with the “Water Law of the People’s Republic of China”, the "Flood Control Law of the People's Republic of China" and the “Regulations of the People's Republic of China on River Management” and in association with the specific circumstances of Huainan Municipality.
275. Codes of Conduct on Commanding and Operation of Main Project Facilities.Codes of conduct will be developed for flood discharge pump stations. Different preventative measures will be taken based on the changes of water levels in the rivers and channels and the results of weather forecast. The flood discharge pump stations should be subject to the overall command of the pump station management office and the commanding activities will be carried out according to the respective rules and on the basis of comprehensive consideration of the meteorological, hydrological, precipitation and working conditions at the time.
276. The management units should carry out inspections of the Project before, during and after the flood season and assure the safety of the Project by means of proper maintenance and management. Non-governmental embankment protection organizations should be supervised and assisted in carrying out the embankment protection and safeguard activities of the Project. The project management agency should develop a series of rules and regulations on plan management, technological management and operation management on the basis of the job responsibility system to make sure that there are laws and regulations to follow for the purpose of continuous improvement of management.
277. Environmental Supervision.Huainan Municipal Environmental Protection Bureau is responsible for supervising and managing the environmental protection activities under the Project, organizing and coordinating the relevant agencies to provide services to the environmental protection work of the Project, reviewing the EIA documents, supervising the implementation of the EMP of the Project, responsible for the final acceptance of the environmental protection facilities of the Project, identifying environmental management laws and regulations and standards to be executed under the Project and providing
200 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment guidance to the county-level environmental protection bureau on the environmental supervision and management of the Project in the construction and operation stages.
278.

280. Project impact monitoring: A qualified monitoring agency is commissioned by HPMO to carry out the monitoring of air, water, and sound environment; The contractor shall carry out periodical monitoring of noise and air quality around the construction sites and submit monthly reports of the monitoring results to HPMO and IA.
281. The environmental monitoring program (as shown in Table VIII-5) of the Project specifies the parameters, locations, frequencies and responsible agencies of environmental monitoring during the construction stage and operation stage of the Project. The environmental monitoring will contain monitoring of the aspects of air quality, noise, aquatic environment quality and ecological environment. Air, noise and water environment monitoring in the construction and operation stages of the Project will be carried out by a qualified monitoring agency commissioned by HPMO.
282. Monitoring of dredging impacts on the water quality of river channels will be carried out by setting up reference cross-sections and impact cross-sections. Free from impacts of the dredging activities, the monitoring sites upstream of the dredged river section will be used as reference while the monitoring stations downstream of the dredged river section will be regarded as impact cross sections. According to the contents of the EMP of the Preliminary Project, any increase in the level of water quality parameter (such as suspended solids SS) at the impact cross section compared to the reference cross section indicate that potential impacts are generated from the dredging activities. If the level of the water quality parameter (SS) at the impact cross section is 130% higher than that of the reference cross section, mitigation measures such as changing the dredging method or reducing the dredging rate will become necessary.
283. Sites for monitoring of ambient air and sound environment quality in the Project are located at representative residential communities or agencies in the region based on the environmentally sensitive sites identified in the EIA Report.

(2) Operation stage
Domestic sewage discharged by sewage pump station staff will be treated in septic tanks and then discharged into the pipelines after treatment; domestic sewage discharged by flood discharge pump station staff should be treated in the underground sewage treatment facilities and used for greening on pump station sites instead of external discharge.
3. Pollution prevention and control measures for noise
(1) Construction stage
The temporary sound insulation barriers or fences around the construction sites should not be less than 3m in height; the operating areas should be enclosed with fences; noises from artificial behaviors such as collision should be reduced, where possible, upon removal of baffles, supports and loading and unloading of materials or debris; idle equipment should be shut off immediately; the respective schools should be consulted so that the construction activities around schools are reasonably scheduled so that school time is avoid school time and high-noise construction activities are arranged on weekends or after school. In the meanwhile, the construction activities round schools should be accelerated and the construction time should be shortened; prior to any construction activities around residential areas, the EA should communicate with the local community offices and have the construction schedule disclosed at entrances and exits of residential areas to inform the residents of any issues for close attention during construction.
(2) Operation stage
Low-noise pumps and equipment should be selected, where possible, and subject to regular maintenance and servicing; the pump stations will adopt a semi-underground configuration to assure reasonable layout of equipment in the station so that all the noise-generating equipment are arranged inside the workshops; upon the installation of pump equipment, soft interfaces will be designed between the pump pipelines and pump equipment; noise reduction will be achieved by means of flexible pipe supports, vibration-reducing bases and noise-insulation covers; sound insulation structure will be adopted for buildings in the pump station to reduce the opening rate of the equipment room. Double glazing windows will be used.
4. Pollution prevention and control measures for solid wastes
(1) Construction stage
The construction units should strengthen the management of domestic wastes on site by providing classified rubbish bins; upon the completion of the Project, the temporary buildings and facilities in the construction areas should be demolished and the construction sites should be cleared, with the domestic solid wastes, simple toilets and sewage pits cleared and leveled and disinfected with carbolic acid and quick lime for proper restoration of the cut-over land during construction. Construction waste soil should be removed out of
222 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
site and transported along specified routes to designated disposal sites and random dumping of construction wastes should be prevented; bulk materials and wastes during transportation should be properly covered up and packed to prevent spillage along the route; vehicles transporting soil must travel along designated routes and within specified time period; dredging wastes must be delivered a disposal area designated by Huainan municipal management authority in a timely manner and uncontrolled disposal is prohibited; the EA must submit a request to the relevant sludge and debris discharge management authority and fulfill the respective formalities for discharge of sludge and debris to get an approval before any such waste soil is delivered to the designated receiving site for disposal.
(2) Operation stage
Grid residues from sewage pump stations should be cleared and transported by the public sanitation department; the domestic solid wastes generated by the staff should be bagged and removed together with the grid residues by the public sanitation department; water surface garbage and water weeds collected in the cleaning process of lakes, reservoirs and rivers should be drained at the water grass collection sites and then transported in time by the public sanitation department. Random disposal of such wastes is not permitted. Adequate number of garbage bins should be provided on the embankment in association with the environmental configuration in the local area to be consistent and harmonious with the local environment; signs and labels for environmental protection should be erected to strengthen the awareness of environmental protection of the local residents and pedestrians;
5. Ecological restoration measures
(1) Construction stage
All the construction activities should be carried out in strict accordance with the scope of construction and within the red line of land occupation to keep the surrounding ecological environment free from impacts; the construction time and progress should be reasonably planned to minimize construction time and avoid construction in rainy seasons; A construction method allowing synchronous excavation and backfill should be used for construction of the sewage pipelines to reduce earthwork excavation, stockpiling and transportation; the river embankment and revetment construction should be carried out on a section-by-section basis allowing synchronization of construction and landscaping; surfaces where the construction works are completed should be compacted and vegetated in time to reduce damages of soil structure and avoid massive soil erosion caused by heavy rain in the rainy season; stronger efforts should be made in protection of the population source in the construction stage of pump station construction and Longyin Lake and corner pond dredging to avoid impacts on biological habitats.
(2) Operation stage
223 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment
A full-time management personnel should be assigned and a routine maintenance system should be established to assure routine watering and maintenance and guarantee the survival rate of planted vegetation; serious attention should be paid to scientific O & M of landscaping and aquatic plants to create long-term ecological landscape; sources of ecological water should be identified for Longyin Lake and the three corner ponds to ensure the realization of the ecological positive effects of the water system rehabilitation works.
6. Conclusion of Comprehensive Evaluation
It is believed in the EIA that, upon the implementation of the Project, the urban domestic sewage collection system, the urban flood control and drainage conditions and the water quality of local ditches, lakes and aquatic ecology will be improved in the urban areas of Huainan Municipality. Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment will generate more positive environmental impacts than negative impacts and will produce significant ecological and environmental benefits. The adverse environmental impacts mainly occur in the construction stage and are local, short and reversible and of a relatively insignificant magnitude and can be mitigated if appropriate environmental protection measures and mitigation measures are taken. Therefore, the Project is environmentally feasible from the perspectives of ecological and environmental protection.

307. The summarized results of the first round of questionnaire survey indicate that 45% of the respondents did know well about the Project, 49% of the respondents had a partial knowledge of the Project and the remaining 6% of them did not know about the Project at all. The respondents mainly get the project information on newspapers, the Internet and television. 80% of the respondents believe that the construction of the Project will remarkably improve urban development and flood storage and drainage in Huainan Municipality while the remaining 20% believe that the Project will help improve the urban development and flood storage and drainage capacity of Huainan Municipality to a certain extent. Regarding the main environmental problems in the project area, 58% of respondents think that the major environmental problem in the project area is water environment, 13% of the respondents regard ambient air problem as the remarkable environmental problem in the project area, and 9% and 22% of the respondents regard noise and solid wastes respectively as the key local environmental problems while the remaining 25% referred to the other aspects. So far as the main environmental impacts to arise during the project construction are concerned, 20% of the respondents expressed their concerns over the wastewater impacts, 42% over noise, 33% over the impacts of exhaust gas and 9% over solid wastes and the remaining 38% regard the other environmental impacts as the ones that they are mostly concerned about. Coming to their attitudes to the Project, 99% of the respondents are supportive to the construction of the Project and 1% of respondents accept the construction of the Project and none of them believe that the project construction had adverse impact on the local water environment.
308. According to the summarized results of the second round of questionnaire survey, 47% of the respondents did know well about the Project, 45% of the respondents had a partial knowledge of the Project and the remaining 8% of them did not know about the Project at all. 74% of the respondents believe that the construction of the Project will remarkably improve urban development and flood storage and drainage in Huainan Municipality; 23% believe that the Project will slightly improve the urban development and flood storage and drainage capacity of Huainan Municipality while 2% believing that the construction of the Project will not bring remarkable changes to the urban development and flood storage and drainage capacity of Huainan Municipality.

So far as the major environmental impacts after the Project is constructed, 25% of the respondents expressed their concerns over the wastewater impacts, 5% over noise, 3% over the impacts of exhaust gas and 12% over solid wastes and the remaining 37% regard the impacts on ecological environment as the ones that they are mostly concerned about. Coming to their attitudes to the Project, 85% of the respondents are supportive to and 15%
234 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment of respondents accept the construction of the Project, with zero objections. 31% of the survey participants are female. There are no particularly disadvantaged households that will be negatively affected by this project.
2. Results of public consultation discussions
309. It is known from the results of public consultation discussions organized by HPMO in the 7 project districts and counties in Huainan Municipality that the participants are supportive to the project in general, but they expressed their concerns and worries about the current condition of water environment pollution. It was generally agreed that implementation of this project would improve the quality of regional water environment and increase the amount of available water resources in the region. The participants suggest that greater efforts are made in environmental management during the construction stage and operation stage to ensure that the Project will play its role in the true sense. In addition, greater importance should be attached to public education to raise the public awareness of environmental protection. With water environment and water resources as the main theme, various types of activities should be organized to enable the public to have more detailed and in-depth understanding of the conditions of local water resources and water environment as well as the proposed measures for prevention and control of pollution.
310. Results of such discussions indicate that most of the participating institutions have no objections to the construction of the Project, believing that the Project will produce positive social and economic impacts. All the respondents are supportive to the construction of the project. However, some participating institutions expressed their concerns on problems of environmental protection that may arise in the construction stage of the Project. For example, the Cultural Relics Bureau requested that protection measures for Shouxian Ancient City be taken in the construction stage of the Project while the Forestry Bureau requested for protection measures for bird habitats in the northeast corner pond.
311. It is suggested in the EIA that the EA should take stronger environmental pollution and control measures in the construction stage. With the measures and requirements proposed in the EIA effectively implemented, it is likely to control the impacts of the Project on the surrounding environment within the scope of national standards and avoid quality deterioration of the residential environment and the environmental impacts that the public is concerned about would be mitigated or eliminated and the public would find the Project acceptable. In addition, continual public participation and survey will be conducted to further understand the public concerns about the impacts of the Project in the construction stage and operation stage.
F. Conclusion of public participation
312. No feedbacks were received by the EA and the EIA consultant during the period of environmental information disclosure. 87.2% respondents are in favor of the construction of the Project while the remaining 22.8% think that the construction of the
235 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment Project is acceptable. No objections are received to the construction of the Project. At the discussions organized by the EA, all the stakeholders and local functional departments expressed their support to the construction of the Project, but they expressed their concerns about the environmental impacts in the construction stage of the Project. Constructive suggestions were received during the discussions from multiple institutions and incorporated into the meeting minutes and then into the EMP after justification. Therefore, the public are supportive to the construction of the Project provided that stronger efforts are made by the EA in environmental management during the construction and operation stages of the Project, the various pollution prevention and control measures proposed in the EIA are conscientiously implemented and a strict environmental management system is developed and put into effect.
G. Continual public participation
313. Public participation is a continual activity to be implemented throughout the different stages of a project, including the preparation stage, the construction stage and the operation stage. In accordance with the EIA requirements of PRC and the public participation requirements of ADB, two rounds of public participation, including a series of public participation activities, were conducted during the project preparation stage.
314. One site investigation meeting will be held per year in the construction stage and in the first 2 years after the Project is put into operation in areas with high concentration of environmentally sensitive targets to listen to public opinions and, when necessary, make improvements to the environmental impact mitigation measures.
315. In the construction stage, public notices will be posted on site to inform the public of the construction stage, operating hours, environmental mitigation measures in effect and the names of the EA, construction contractors, the environmental protection agencies and their contact persons and telephone numbers. Timely responses will be made to the opinions raised by the public in the construction stage and the construction activities will be arranged in a coordinated manner to minimize the environmental impacts of the Project.
316. Interviews or discussions may be conducted in the operation stage of the Project to solicit the opinions and suggestions of the affected residents and the social communities; further mitigation measures may be taken if necessary. The plan of continual public participation program is shown in Table IX-8.

X. GRIEVANCE REDRESS MECHANISM
A. Purposes
317. Environmental and social issues raising public concern are already discussed in the public participation, consultation and information disclosure activities as a part of the local EIA process. However, there may still be some unpredictable problems. In order to address such problems, it is necessary to set up effective and transparent channels for receiving and handling complaints and appeals. It is required in the ADB Safeguard Policy that the Implementing Agency shall establish and describe a mechanism that can receive and speed up the resolution of complaints and grievances from the APs on the environmental aspect of the Project. The grievance redress mechanism should be consistent with the risks and adverse impacts of the Project to facilitate settlement of problems and complaints of the affected population in a reasonable, transparent and timely manner and should allow free and harmless application in each and every part of the region.
B. Grievance redress mechanism
318. Under the existing mechanism, the affected public mainly appeal to the contractors, the EA, the local government or the local environmental protection bureau and, as the last resort, to the court.
319. In the construction stage and operation stage of the Project, the contractor and the IAs shall assign a special personnel to be responsible for handling complaints from the affected people, making public the complaint hotline and accept public consultation and complaints.
320. The affected public are entitled to making complaints about any environmental issues. The contractors and other appellant units are supposed to accept and handle the public complaints free of charge, with costs and expenses incurred from accepting and handling complaints deducted from the contingency fund of the Project. Minor issues should be resolved within a week while major ones within a month.
C. Procedures
321. There are multiple grievance redress channels available to the affected persons, such as face-to-face meetings, written complaints, hotline complaints, anonymous drop-boxes, and/or e-mail. Upon the receipt and registration of a public complaint by the contractors, HPMO, HEPB or ADB, the grievance redress agencies need to have complaint forms and written records available in the office and the staff of the grievance redress agencies shall classify and number all the complaint issues, such as (1) time of receipt, (2) contact information of complainant, (3) type of complained objects (e.g., air, water, solid waste, noise), (4) specific causes of the complained incident, (5) complaint
238 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment handling personnel . The grievance redress agencies shall develop a written confirmation in 5 workings days after the receipt of the public complaint. All complaints as received shall be subject to confidential treatment in a professional way. Disclosure to the project agencies or staff of the identity information of the relevant persons is not permitted and such information may be shared with senior staff only when clearly justified. HPMO shall report the progress to ADB, including information on complaints and their resolution, in the construction stage and the early stage of the operation stage covered by the loan covenants.
D. Feedback mechanism
322. Here described as follows is the feedback mechanism of the grievance redress agency for any complaints made by the affected people in the construction and operation stage of the Project.
lxxi. For environmental problems arising during the construction stage, the affected persons (APs) may register their complaints directly with the contractors as well as the HPMO, the IAs, HEPB or ADB. The contractors are required to set up a complaint hotline and anonymous drop-box and designate a person to be responsible for handling complaints and make public the complaint hotline number at the main entrance to each construction site. The contractors shall maintain and update the complaint register to document and update all complaints. The contractors shall respond in writing to each and every complaint of the complainant within 7 calendar days to explain the proposed solution and how it will be implemented Unless in the case of an anonymous complaint, The grievance redress procedure shall not end until the complained problem is resolved and the complainant is satisfied with the resolution. The contractors shall summarize and report all complaints received, handled, resolved and unresolved to the IAs and HPMO on a monthly basis. lxxii. For environmental problems unlikely to be resolved at the contractor level, the affected person shall submit the complaints to the IAs. Upon the receipt of such complaints by the IA or HEPB, the receiving party shall notify the other party of and record in writing the contents of such complaints in the Complaint Register. The IA shall immediately inform the HPMO Environmental Specialist of the contents of complaint and agree on an action plan. The IAs and HEPB shall respond in writing to each complaint within 14 calendar days to explain the proposed solution and how it will be implemented. If the problem is resolved and the complainant is satisfied with the solution, the IAs shall record the complaint contents and resolution process in the Complaint Register and report to the HPMO on a quarterly basis. lxxiii. Complaints submitted to HPMO (with the environmental or social specialists of HPMO being the responsible person) shall be handled by HPMO within 14
239 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment calendar days as of receipt of such complaints. After the complaints are put on record, HPMO shall immediately notify ADB. An explicit reply shall be made to the complainant within 14 days as of the date of recording and receipt of such complaints after the complaint contents and potential solutions are discussed by ADB, HPMO, LIEC, contractors and the APs. lxxiv. If the affected person is not satisfied with the solutions proposed in Step 3 above, he/she may, upon the receipt of a response, make a complaint to HEPB. Upon the receipt of such a complaint, HEPB shall record the complaint contents and give a notice to HPMO while HPMO, upon receipt of the complaint information, shall immediately notify ADB. After the complaints and potential solutions are discussed among ADB, HPMO, LIEC, the contractor, and the affected persons, HPMO shall give an explicit response to the complainant within 14 days as of the recording and receipt of the complaint. lxxv. If the affected person is not satisfied with the solutions proposed in Step 4 above, he/she may, upon the receipt of a response, make a complaint to ADB. Upon the receipt of such a complaint, ADB shall record the complaint contents and give a notice to HPMO. HPMO, upon receipt of the complaint information, shall handle the complaints within 14 days.

XI. CONCLUSIONS AND RECOMMENDATIONS
A. Conclusions
324. In this EIA, analysis was conducted over the status quo of the air environment, acoustic environment, water environment and sediment and ecological conditions of the affected areas involved in the construction of the Project. Results of such analysis indicate that the quality of all the environmental elements other than water environment meets the requirements of the local water environment functional zoning plan.
325. Analysis and prediction of the environmental impacts during the construction and operation of the Project indicate that: The key impacts on the air environment in the construction stage of the Project are from dust and a small amount of exhaust gas emitted by mechanical plants and such impacts are temporary; the Project is expected to generate short-term and intermittent impacts on the acoustic environment in the construction stage; with small impact on the water bodies, the Project will involve no impacts on the groundwater. With the corresponding mitigation measures implemented, the aforesaid impacts will be significantly reduced. Dust, tail gas and wastewater will disappear at the end of the construction stage and no irreversible negative impacts are involved. The main impacts on Shouxian Ancient City Wall in the construction stage will be generated from mechanical vibration and construction dust, which will disappear as the construction stage comes to an end. Negative impacts will be generated from the construction activities on the daily inhabitation of the egret found in the northeastern corner pond of Shouxian County and such impacts will disappear as the construction activities come to an end. The main impacts in the operation stage come from pump station noise and such impacts can be minimized to meet the requirements of the respective national noise standards if respective mitigation measures are taken. With the aforesaid measures taken, the Project will generate minimal negative impacts on local environment in the operation stage.
326. It is known from the above assessment and analysis that the adverse impacts on environment generated by the project are minimal after taking corresponding mitigation measures during construction.
B. Recommendations
327. As for the construction which will affect the Shouxian Ancient City, the mitigation measures should be re-evaluated before the construction to see whether they are effective, and mitigation measures should be added if necessary.
328. For all the construction works affecting Shouxian Ancient City, the environmental mitigation measures shall be subject to effectiveness re-evaluation and additional mitigation measures may be included if necessary.
329. It is already confirmed during the preparation of this Report that the egrets
242 Environmental Impact Report of Anhui Huainan Urban Water Systems Integrated Rehabilitation Project: Mid-term Adjustment inhabiting in the northeast corner pond of Shouxian County are common wild birds, not belonging to special protected birds. Before the commencement of the Project, the project owner needs to re-confirm whether the birds inhabiting the corner ponds are protected species and re-check the effectiveness and reliability of all the mitigation measures proposed in the report. Mitigation measures for impacts on birds may be added or strengthened based on the adjustment and needs at the time.
330. In order to reduce the impacts on the birds in the northeast corner pond, construction process with lower direct impacts should be considered in the project design.
