Background and Objectives of Environmental Management Plan (EMP) 1.1 Project Background With the rapid development of economic in suburb, including overall construction of Xixia District, Xianlin New Town Area and Longtan New Town, and further acceleration of urbanization, water demand in the northeast of Nanjing urban area has a large increase. There is a big gap in the regional water supply quantity and the obvious contradiction between water demand and water supply. Longtan New Town, Xixia District and Xianlin New Town Area are located in the northeast of Nanjing urban area. Making the best of its riverbank resource, Xixia District recently fulfilled the development and construction along the Yangtze River. Regional economic and social undertakings have developed rapidly: Huaneng Jinlin Coal-fired Power Plant, Huaneng Jinlin Gas Power Plant and Nanjing Crystal Valley have been settled; North City Market Group and 312 State Road Economic Zone have taken on a certain scale; tourism and real estate sectors have shown a good momentum of development. Being close to the urban city, Xianlin New Town Area uses its location advantages to actively develop the real estate and infrastructure construction: Xianlin Campus City has basically taken shape and other constructions are in full swing. Faster development of regional economic and constructions require the improvement of quantity and quality of water supply in this region. However, the existing water treatment plants in the northeast area are township water treatment plants or enterprise-owned waterworks which are small in scale with backward technology and outdated equipment, coupled with backwardness of management and technical. The current water facilities cannot meet the increasing demands of water quantity and quality, as the result the contradiction between water supply and demand becoming prominent. Thus, it has created severe negative impacts to the quality of life and health of the residents, as well as the rapid economic development activities. In order to better adapt to the city development and increasing demands of water quantity and quality, Nanjing Municipal Government planned to implement the First Phase Project of 1 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan the Longtan Water Treatment Plant (400,000 m3/d), consisting of water intake project, water treatment plant project and associated works such as water transmission pipes. The total investment was estimated to be RMB 681.5046 million, with US$ 13 million to be funded by the World Bank (WB) (equivalent to RMB 89.18 million) and the rest from domestic bank loans. Considering the short of domestic fund, Jiangsu Provincial Government proposed to use the WB loan to accelerate the construction and fulfillment of the first phase of the project. Using the WB loan to construct the Longtan Water treatment plant will ease up the pressure of water supply in Nanjing and help boosting the development of city and improving the living standards. Based on the project characteristic and location Environmental features, according to the Law of Environmental Protection of P.R.C, the Interim Regulations on Giving Punishments for Illegal Acts and Disciplinary Offences in Environmental Protection, the Regulations on the Administration of Construction Project Environmental Protection, the Law of Air Pollution Control of P.R.C, the Law of Water Pollution Prevention and Control of P.R.C, the Law of Ambient Noise Pollution Control of P.R.C, the Regulations on City Appearance and Environmental Sanitation Management and etc., this EMP is using relevant policies as guidance to realize the purpose of develop economic and protect environment. The overall principle is to control the pollution from the source to the end of treatment to ensure the effective management. The EMP is focus on the project features and addressing on the main Environmental problem, carrying out the requirements of “Cleaner Production�, “Discharge Standard� and “Total Control�. The EMP details the monitoring, supervision and control measures on Environmental impacts during construction and operation stage of project to ensure minimum these impacts. The selected Environmental protection measures are technology-reliable and economic-reasonable. 1.2 Objectives of the EMP The Environmental Impact Assessment (EIA) of the project demonstrates that the main pollution is from the newly-built water treatment plant during construction stage and operation stage of all water treatment plants. This EMP details the mitigation, management, supervision and monitoring measures, which are the guidelines of these activities. The roles of the EMP are as follows: 2 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan (1) Define the Environmental mitigation measures of affected objects. Nanjing Environmental Protection Bureau (EPB), EIA company and design institute have checked and confirmed the affected objects to propose effective mitigation measures which are brought into the project design. (2) Provide Environmental guidelines. After reviewed by the WB, this EMP will provide an Environmental protection reference for all concerned parties, including construction observation companies, Environmental supervision departments and other relevant departments during construction and operation phase. (3) Determine the responsibilities and functions of relevant parties. The EMP determines the responsibilities and roles of relevant functional departments and governing institutions and provides communication channels and manners between each party. (4) Propose Environmental monitoring plans. In order to ensure effectively implement mitigation measures and timely deal with the unforeseen or unexpected Environmental issues, this EMP proposes the monitoring plans during construction and operation stages. 1.3 Program of action and requirements With the joint efforts of WB officials, international consultants, EIA unit and Nanjing EPB, this EMP constitute the overall objectives of the project during construction and operation stage, including maintaining socio-economic and environmental sustainability, improving the Environmental quality, mitigating or compensating for the negative impact to the community and the environment, until the minimum.

Environmental Impacts and Mitigation Measures 4.1 Analysis of environmental impacts 4.1.1 Analysis of environmental impacts during construction period 4.1.1.1 Analysis of acoustic Environmental impacts The impact of construction noise on ambient acoustic environment is evaluated by adopting Noise Limits for Construction Site (GB12523-90) (shown in table 4.1.1.1-1). Table 4.1.1.1-1 Limiting values of noise at different construction stages Limiting values dB(A) Construction period Main noise source Day Night Cubic meter of earth Bulldozer, grab, loading truck, etc. 75 55 and stone Piling Various pile driver 85 Ban Construction Concrete mixer, vibrating tamper, 70 55 electrical saw, etc. Fitting Crane, elevator, etc. 65 55 As the noise caused by construction machines is mainly in middle and low frequency, only diffusion attenuation would be taken into consideration when predicting the noise impact. The predication mode is as following: L2�L1�20lg (r2�r1) （r2＞r1） L1, L2 – equivalent sound level A (dB(A)) at r1,r2 r1, r2 – distance from acceptance to noise source (m) derived the attenuation difference of sound level through distance ΔL: ΔL�L1�L2�20lg（r2�r1） From the former formulation, it could be calculated the attenuation value of noise through distance, seeing table 4.1.1.1-2. Table 4.1.1.1-2 Attenuation value of noise through distance Distance 1 10 50 100 150 200 250 300 400 600 (m) ΔLdB(A) 0 20 34 40 43.5 46 48 49.5 52 55.6 According to the highest sound level machine listed in table 4.1.1.1-1, the attenuation 20 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan value of construction noise through distance is shown in table 4.1.1.1-3. Table 4.1.1.1-3 Attenuation value of construction noise through distance Distance Type of machine 10 50 100 150 200 250 300 400 (m) Pile driver Noise 100 86.0 80.0 76.5 74.0 72.0 70.5 68.0 Concrete mixer value 84.0 70.0 64.0 60.5 58.0 56.0 54.5 52.0 Grab, crane, camion dB(A) 82.0 68.0 62.0 58.5 56.0 54.0 52.5 50.0 From the table 4.1.1.1-3, it could be concluded that it would reach the limiting value of noise beyond 100m by day and 300m by night( pile driver is forbidden to operate at night). The acoustic environmental protection target is Xihua village, which locates at 200m outside the scope of construction. According to the calculation, the construction noise at night would cause certain bad influence on the villagers. It should be forbidden to operate high frequency machine at night to mitigate the influence. 4.1.1.2 Analysis of aqueous Environmental impacts （1）Industrial wastewater Industrial wastewater consists of cooling and washing water of all kinds of machinery, waste water from washing construction site and material, and pressure testing water, which contains some oil and sand. （2）Domestic wastewater Domestic wastewater is from the activities of workers, including eating, washing and toilet. There would be about 50 worker on the site. Assumed average wastewater quantity 100L/person/d, main pollutants COD (300mg/l), SS(200mg/l) and NK(30mg/l), the total quantity of domestic wastewater and concentration of discharged pollutants are shown in table 4.1.1.2-1. Table 4.1.1.2-1 Domestic wastewater quantity and concentration Quantity SS COD NK Workers （t/d） （kg/d） （kg/d） （kg/d） 50 5 1 1.5 0.1 Although there is relatively small quantity of wastewater, it would cause obvious water pollution if no or improper treatment. The wastewater should not discharge directly and need adopting mitigation measures. 21 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan 4.1.1.3 Analysis of atmospheric Environmental impacts During construction, the air pollutants mainly are: （1）Exhaust gas The exhaust gas is mainly from mechanical driver equipments (for example, diesel engine), transportation vehicles and fuel. The main pollutants are NOx, CO and hydrocarbon. （2）Dust The dust is mainly from: ① earthworks (excavation, piling up, removal, backfilling and site preparation) ② transportation ③ assembling, transporting and piling up of construction materials (such as cement, lime and sand) and earthwork ④ ground dust caused by mixer and transporting vehicles ⑤ piling up and removal of solid waste The exhaust gas and dust would cause ambient air pollution, especially the dust. The dust pollution depends on the construction practices, materials stacking and wind power, the last one affecting the most. With the increase of wind speed, the extent and scope of dust pollution would subsequently enhance and expand. At construction stage, with the construction activities, including excavation, loading and transportation, the dust would adversely affect the neighboring air environment. Reasonable and practicable control measures must be taken to minimize the degree of pollution, narrowing the incidence. 4.1.1.4 Analysis of solid waste impacts The solid wastes mainly consist of earth from excavation, waste construction materials (such as sand, lime, concrete, bricks and stones), and domestic solid waste. If the construction garbage piles up for a long time, it would generate dust; if the domestic solid waste could not be timely cleared up and transported, it would rot and breed flies and mosquitoes, resulting in noxious odors and infectious diseases, which adversely affect the surrounding environment and workers health. The excavated earth and stone is about 84000m3, most of which is back filled. There is about 76000 m3 earth and stone used for back filling the pond and other depression 22 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan construction area and the rest 8000m3 could be piled up in the blank on the north side of the plant, the piled height about 0.2m, which needs timely vegetation recovery. 4.1.1.5 Analysis of ecological Environmental impacts （1）Impacts of ecological environment in the waters The water intake project would increase the concentration of suspend solids in local water bodies, affect fish habitat and cause adverse affection on hydrobios. The constructions temporarily narrow down the scope of fish activities. This section of river is about 2200m wide and the head of water intake is 240m from the dam. The underwater construction is about 200m wide, accounting for 9% of the total width, so that there are relatively small impacts on the migration routes of fish and other aquatic organisms. If the construction period chooses to be undertaken in winter, it would avoid the spawning migration of fish and other aquatic organisms. After the completion of the project, the water intake head will extend into the river for about 200m. Except the head of water intake, fish could pass over the pipeline. Because the relative decrease of river cross-section, the impacts on fish are comparatively small. The project is located at a wide river section with strong tidal action. The water taking by proposed project will only have very minor impact on the water level of water-taking river section, which will neither result in the dramatic decline of water level at the water-taking river section, nor lead to significant impact on water ecosystem for the downstream section of Yangtze River. Therefore, the water taking by the project will not lead to significant decrease of water quantity and dramatic decline of water level in the water-taking area, and it will affect regional water resource utilization. In comparison to the whole Yangtze River, the water taking quantity by the project is not significant, so the impacts on roes and fries in the water area during water taking process are relatively minor. In addition, roes and fries mainly float in the water and soil about 3m on the surface. The water intake for the project has topographically avoided the surface layer with many activities of fishes and shrimps, which can reduce the impacts of water taking on roes and fries. The domestic wastewater and industrial wastewater is not discharged into the Yangtze River, which would not affect the water ecosystem in the waters. （2）Impacts of terrestrial ecological environment Construction activities will cause loss of partial terrestrial ecological environment, 23 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan including about 275mu reed beach and pond inside the dam changing into plant area. In the later period of construction, greening and shelter belt will be constructed at the plant boundary and in the assisting districts for production and living. The greening area will reach 71500m2 and the green coverage 39%. The loss of terrestrial ecological environment will receive the maximum recovery. 4.1.2 Analysis of environmental impacts during operation 4.1.2.1 Analysis of aqueous Environmental impacts （1）Industrial wastewater The industrial wastewater consists of the sludge water of laminar settler tank and back-wash waste water of sand filter. Daily discharged volume is 3-4% of the produced volume and the maximum tail water capacity is 16000 m3/d (5840000 t/a). Sludge water accounts for 40% of tail water, that is 6400 m3/d (2336000 t/a), flowing into sludge water treatment system; back-wash waste water accounts for 60%, that is 9600 m3/d (3504000 t/a), recycling directly. After condensed by thickener, the supernatant of sludge water capacity is 6300 m3/d (2294000 t/a), flowing into reclamation tank; the rest enters into dehydration room and after dehydration the separated water capacity is about 10350000 m3/d (378000 t/a). The mud cakes weigh 115 t/d (42000 t/a) and solid content is 40%. Designed dried mud is 46.2 t/d (17000 t/a), containing water 68.8 m3/d (25000 t/a). In summary, the industrial wastewater (back-wash waste water, supernatant from thickener and wastewater after dehydration) is entirely reused and the recycling rate is 100%. （2）Domestic waste water There are 60 staffs in the plant. The average water consumption is 150 L/d and the sewage discharge ratio is 0.8. The domestic wastewater capacity is 7.2 t/d (2628 t/a), discharged into municipal sewage network. The main pollutants of wastewater and planned treatment measures are listed in table 4.1.2.1-1. Table 4.1.2.1-1 Main pollutants of discharged wastewater Item Waste Main pollutants Treatment 24 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan water measures Concentration Capacity capacity Name (mg/L) (t/a) (104 t/a) Industrial 229.4 SS 100 229.40 reuse wastewater CODCr 300 0.79 Domestic into sewage 0.2628 SS 200 0.53 wastewater network NK 35 0.09 4.1.2.2 Analysis of acoustic Environmental impacts Main noise equipments are back-wash pump, blower, water supply pump, sludge dehydrator and water intake pump. The back-wash pump house is built together with air blower house. Main noise sources are detailed in table 4.1.2.2-1. Table 4.1.2.2-1 Main noise sources and sound-proof effects Noise source Measure Measure noise value Sound-proof noise value Quantity 1m away the effects Item Name in the house house (dB(A)) (dB(A)) (dB(A)) Back-wash pump 3 85～95 / 20* Blower Water Water treatment supply 5 83.0～84.3 60.0～62.0 22.2～23.4 plant pump Sludge 2 85～95 / 20* dehydrator Water intake Water 4 83.7～85.3 60.7～62.4 22.9～23.3 pump intake pump house Note: The measured noise values of back-wash pump, blower and sludge dehydrator are analogy results. 4.1.2.3 Analysis of solid waste impacts Solid wastes at operation stage mainly are mud cakes after dehydration, capacity 115 t/d (42000 t/a) and water-containing rate 60%. There are 60 staffs in the project. If the domestic solid waste generation is 1 kg/person/d, the capacity is 21.9 t/a. Solid waste source and planned treatment measures are listed in table 4.1.2.3-1. 25 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Table 4.1.2.3-1 Solid waste generation Planned treatment Item Capacity (t/a) Moisture content (%) measures Multipurpose Sludge 42000 60 utilization and sanitation landfill Removed and Domestic solid transported by 21.9 / waste Environmental sanitation sector 4.1.3 Indirect Impacts The wastewater from new Longtan City, Xixia District and Xianlin new urban area is all discharged into Xianlin WWTP. Xianlin WWTP is situated in Daijiaku Village of Xixia District, which serves the Xianlin university city and surrounding areas. The WWTP is designed with the total capacity of 250,000m3/d and is planned to be constructed phase by phase. The currently built Phase I project occupies the land surface about 3.95ha, which was completed and put into operation in August 2008 with the treatment capacity of 50,000m3/d. Nanjing Xianlin WWTP adopts CAST wastewater treatment process, which is featured by small land use, compact layout, concentrated equipment and high level of automation. The wastewater generated by the WTP will be discharged into Nanjing Municipal Xianlin Wastewater Treatment Plant through the municipal sewage network. All the wastewater generated by the WTP will be treated by the WWTP to meet the standard requirements before discharge with minor environmental impacts. 4.2 Environmental Protection Measures 4.2.1 Protection of Water Intake To mitigate the impacts of water intake on ambient environment, the following measures should be taken: (1) The terrain elevation near the water intake avoids the surface layer with many activities of fish and shrimps. It is lower than the water depth for fish migration 26 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan and higher than the sphere of activities for benthic organism, which can reduce the impacts on aquatic organisms. (2) The water intake is designed with coarse bars and rotatory screen to reduce the impacts on aquatic organisms. 4.2.2 Mitigation measures during construction period 4.2.2.1 Mitigation measures against acoustic impacts To mitigate the construction noise impacts, the following measures should be taken: (1) To enhance construction management, reasonably schedule construction activities timeline, notify the local citizens; strictly comply with the relevant provisions of the construction noise management, implement Noise limits for Construction Site and strictly prohibit carry out high-frequency noise construction activities at night. (2) Preferably use low-frequency instruments, for example using hydraulic tools instead of pneumatic tools; adopt low noise construction practices as far as possible. (3) Machinery should be located at the position which would cause the least impacts on the surrounding residents, that is in the side close to the dam, and keep away from the southwest settlement. (4) Sound proof measures should be implemented on construction site, such as setting screens around high-frequency equipments, placing the high-frequency small machines (electronic saw, etc.) inside the room and blocking out the construction site by adcolumn. (5) To enhance management of transportation vehicles, specify vehicle routing, as far as possible reduce the quantity and density of vehicles and control the whistling. Adopting the above measures, the noise value of construction site would meet the limits of Noise limits for Construction Site. The impacts on Xihua Village would be very small. 4.2.2.2 Mitigation measures against aquatic ecological impacts Protection and control measures mainly are: (1) To enhance management at construction period; aiming that wastewater generation is not continuous and categories of wastewater are relatively single, corresponding measures should be adopted to effectively control wastewater and capacity of pollutants. (2) Temporary septic tank should be built in the living quarters of labour camps and 27 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan domestic sewage should be discharged into septic tank and used as agriculture or green fertilizer for nearby residents. (3) According to local condition, temporary wastewater treatment facilities should be constructed, such as settling tank, oil separator and drainage ditch. High oil content washing wastewater of machinery and high suspending solid content wastewater should be treated by oil separator and settling tank until meet the standards and then be discharged. The supernatant liquid from settling tank could be used for aspersion and as spray for dust suppression. Wastewater from mortar and lime slurry should be treated together. After desiccation, solid should be treated with solid wastes. (4) Construction materials such as cement, sand, lime, etc. should be piled together and corresponding scour protection measures should be adopted. The spilled building materials during transportation should be removed and cleared in time and treated nearby or with solid wastes to avoid being washed by rain and contaminate nearby water bodies. (5) The project construction will be scheduled in winter to avoid the spawning and migration periods of aquatic organisms such as fish. After the project is completed, the head of water intake will be about 200m into the river. Other than the head of water intake, fish can still pass over the pipe, therefore, the impacts on fish resulting from relevant decrease of river cross-section will be minor. None of the domestic and production wastewater from the project will be discharged into Yangtze River; therefore, there will be no impact on water ecosystem. 4.2.2.3 Mitigation measures against atmospheric impacts Main mitigation measures are: (1) Management should be rationalized on construction site. Sand and stones should be stored together. Cement should be stored at a dedicated warehouse. Try to reduce the process of handling and gently convey to prevent rupture of packing bags. (2) Mainly use mechanical tools at earthwork and try to reduce construction time. (3) Frequently asperse the construction site and earth deposit. Properly water the operation space and piled earth at excavation to keep certain moisture and reduce dust. Timely back fill the excavated area after completion of pipe laying. The excavated earth and stone and building materials should be transported in time to prevent generating dust because of surface dryness caused by long time stack or rain erosion. (4) Transportation vehicles should be in good condition and not over loaded. Coverage 28 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan and closure measures should be adopted to reduce spillage along the road. Timely clear and remove the spilled earth and building materials and flush the tyres and regularly watering to reduce the dust in the process of transportation. (5) Mixing mortar and concrete on site, try to do with nothing spilled, nothing leaked, nothing left and nothing dumped. Concrete mixer should be located in the shed and there should adopt spray for dust suppression when mixing. (6) Enclosure should be installed or partially installed on site to reduce the diffusion scope of dust. (7) When wind speed is excessively great, construction activities should be held on and covering measures should be adopted on piled building materials. (8) Construction machines which generate a great deal of smoke should be equipped with smoke-absorption devices to mitigate the air pollution. 4.2.2.4 Mitigation measures against solid wastes impacts All the solid waste generated by the project will be sent to Nanjing Jiaozishan Solid Waste Disposal Site. Nanjing Jiaozishan Solid Waste Disposal Site is located near Doucun Village in Qilin Neighborhood in Jiangning District of Nanjing Municipality. It was constructed in 1992 and put into use in 1993. The land use is 420mu. It is designed with the capacity of 1.5million m3. The disposal site mainly consists of three parts including landfill area, wastewater treatment system and office building. To prevent the direct flow of storm water from surrounding mountains into the site, the cut-off ditches are constructed surrounding the three landfill areas along the mountain ridge. The bottom of three landfill areas is installed with separate storm water and sewage drains, which are respectively connected with the clean water tank and wastewater tank downstream of the landfill site. The clean water is directly discharged into the local river, while the wastewater is pumped to the WWTP for treatment. The daily treatment capacity of wastewater is 240m3 and 400m3. Currently the site is in normal operation. (1) Timely clear up the construction site, collect the domestic waste produced by workers and remove it in time. (2) Try to reuse the valuable building garbage and the rest should be removed and transported in time. (3) As there are lots of ponds and bottom land in the project location, most part of waste spoil could be back filled and the rest could be stacked on the blank in the north side of plant 29 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan close to the dam. The pile is about 0.2m high and the cover should be timely revegetated. 4.2.3 Mitigation measures during operation 4.2.3.1 Protection measures of water source (1) Point source and non-point source control ① The planned manufacturing projects in Xixia Economic Development Zone should adopt total amount and concentration control. Besides that water quality must meet the national discharge standards, in compliance with the principle of total amount control, the newly increased emissions amounts must be balanced in the region and should not exceed the sum of emissions reductions. ② The imported industry in the vicinity of water intake should mainly be high-tech industry and avoid introduction of the industrial project which generates a great amount wastewater and high concentration organic pollutants. The Management Committee of Xixia Economic Development Zone should strictly control the import of industry and environmental protection sector should take the responsibility of single-vote veto for heavily polluting projects. ③ With the development of local economic, the population will quickly increase. In order to prevent domestic wastewater polluting the Yangtze River, the improvement of pipeline network should be completed as soon as possible. Domestic wastewater and industrial wastewater in the Development Zone should be treated by water treatment plant and reach the emission standards. ④ To carry out standardized regulation on Jiuxiang River and Qixiang River, strictly inspect and supervise the illegally discharge in to rivers, set up on-line monitors at sewage outfalls to on-line monitor the pollution discharge units. Once find the over standard discharge, notify the waterworks to respond in time. ⑤ Regularly inspect the berthed ships on Sheshan Base Wharf and conveyance ships on Yangtze river waterway to prevent leakage of oil. Once leakage occurs, implement emergency measures in time and notify the Longtan water treatment plant at the first time. ⑥ All kinds of enterprise in the evaluation district should regularly inspect the wharves, conveyance ships and transporting pipelines to prevent leakage of hazardous materials and oil. Once leakage occurs, implement emergency measures in time and notify the Longtan water 30 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan treatment plant. ⑦ All kinds of enterprise in the evaluation district should establish emergency plans and precaution measures to protect the water source for pollution incidents and carefully put these plans and measures into effect. Depending on the situation of leakage, waterworks could suspend the water supply and use the emergency water source from Chengbei water treatment plant. Waterworks should start operation after the restoration of water quality. (2) Control measures of water source protection zone ① Management of protection zones at all levels in Longtan waterworks should be compliance with the relevant provisions from Regulations of Protection and Pollution Control for Drinking Water Source Protection Zone, Regulations of Urban and Township Water Supply Source in Jiangsu province and Regulations of the Yangtze River Protection and Pollution Control in Jiangsu province.

The existing units which pollute water supply source must undertake treatment within limited period to ensure that water quality of water source satisfy national standards. If not, the units must stop production, transform or remove. Shelter belt should be gradually established along the bank. ④ Quasi-protection zones: it is forbidden to any activities that destroy the ecological Environmental balance in the water and destroy water conservation forests, bank protection forests and any vegetation related to water source Environmental protection; it is forbidden to dump industrial waste, domestic garbage, wastes and other solid wastes into the water bodies; ships and vehicles transporting hazardous materials, oil and wastes are generally not allowed to enter protection zones, and necessary entrants need apply for permission of relevant sectors in advance, get official approval, register and be equipped with prevention facilities of seepage, spill and leakage; it is forbidden to utilize highly toxic and high residual pesticide, to abuse fertilizers and to catch fish with dynamite and poison; it is forbidden to construct and expand any projects that discharge pollution containing persistent organic pollutants, mercury, cadmium, lead, arsenic, sulphur, chromium, cyanide and etc.; it is forbidden to construct and expand any projects in the following industry, including chemical pulping and papering, tanning, electroplating, printed circuit board, printing, dyeing, oil refining, coke, pesticides, asbestos, cement, glass and smelting; it is forbidden to discharge any pollutants that are listed in the catalogue of organic toxic materials in Jiangsu province; it is forbidden to construct golf course, waste recycling (processing) plant, hazardous materials warehouse or stack, or coal field, ash yard and landfill; it is forbidden to construct and expand any other projects that severely pollute water bodies and to carry out any activities that is forbidden by laws and regulations. In the quasi-protection zones, reconstructed projects should reduce the emission capacity. ⑤ The scope of production district of waterworks should be indicated with obvious 32 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan signs. It is not allowed to set up residential areas and build livestock farming plants, seepage latrines and soakaway in the periphery of waterworks within less than 10m; it is not allowed to stack garbage, wastes and industrial wastes or lay sewage channels; it should keep good sanitary condition and do well in green. ⑥ In case of incidents and other break-outs, which could cause or possibly already have caused contamination accidents, pollutant discharging unit must implement emergency measures to eliminate or mitigate pollutions, timely inform waterworks and report to local environmental protection sector; ships that cause accidents should report to nearby harbor superintendence administration and accept for investigation and treatment. ⑦ To prevent oil pollution in water bodies, any motor vessels should be equipped with oil and waste storage devices to timely recover the residual oil and waste oil; motor vessels with above 15 dead weight (containing 15t) and non-motor vessels with above 40 dead weight (containing 40t) should be equipped with wastes and garbage containers. ⑧ To enhance the construction of wastewater treatment infrastructure in Xixia Development Zone, to ensure that wastewater of enterprises in the Development Zone are collected and treated in wastewater treatment plant and attain discharge standards after the completion of this project. ⑨ To deploy full-time environmental protection staff taking charge of routine management and supervision of water source protection. 4.2.3.2 Wastewater treatment measures Industrial wastewater from water treatment plant consist of back-wash wastewater of filter, supernatant liquid of thickener and separating water after dehydration, among that the back-wash water and separating water could be directly reused, supernatant could go back to mechanical mixing and be reused, recycling rate 100%. Back wash waste water is discharged into drainage tank, then elevated to the front part of treatment system to be reused directly. Sludge water of settling tank is transported by pipeline to sludge tank. After certain period of settling and concentration, supernatant liquid is reused in the mechanical mixing tank which is in the first part of water production process. Sludge after concentration is dehydrated by dehydration pump. Separating water is reused in sludge tank and mud cake is transported to landfill. 33 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Through the above process, there is no wastewater discharge in the production process. 4.2.3.3 Acoustic environmental pollution control measures Noises during operation period mainly are from back wash pump, water supply pump, and sludge dehydration pump. Implementing the following noise control measures could ensure that noise value at the plant boundary attains standards and there is no impact on the residential district around the plant boundary. (1) Purchase low-frequency instruments and implement shock absorption and noise reduction measures, equip blower with intake and exhaust muffler and coverage, adopt shock absorption measures at installation, use noise adsorption material at fitment of pump house, reduce the noise level in the pump house to satisfy the sanitation standards for industrial enterprises. (2) In the total layout, locate the noise source as far as possible from the plant boundary and protection objects. Pump house should be far away from the centralized place. Operating room and pump station should use double layer doors and windows and be equipped with sound insulation rubber band. At the premise of lightening and ventilation, the window areas of pump house should be designed as small as possible to mitigate the impacts of motor noise on staff and surrounding environment. (3) Implement integrated green, planting flowers, grass and forests, at the boundary of water treatment plant to further mitigate noise impacts. 4.2.3.4 Solid waste pollution control measures (1) Sludge treatment measures At present, most national water treatment plant have not implement sludge treatment and the normal practice is discharge directly or after simple settling. Concentration and dryness of sludge water is commonly used abroad. In this project, sludge treatment device is installed to concentrate and dehydrate the sludge water and the final solid waste is sludge cake with capacity of 115 t/d (42000 t/a) and moisture 60%. Water source of Longtan waterworks is from the Yangtze River and sludge mainly compose of inorganic substances which are non-hazardous, non-toxic and innocuous, have relatively good environmental acceptability and usually cause no adverse impacts on environment. For the treatment of sludge cake, the 34 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan first consideration is comprehensive utilization. Nanjing Water Supply General Company considers using sludge for road construction and back-fill of municipal engineering project in the aspect of cleaning production and circular economics. The rest sludge would be regularly cleared and collected by plant part and transported to Jiaozishan waste disposal site used as coverage earth of landfill. (2) Domestic waste treatment measures As located in Xihua village, domestic waste of this project could be collected and treated by environment and sanitation system of Xihua village district. After being packed, domestic waste is cleared and transported to Xincheng waste transfer station by villager committee of Xihua village district, then collected by environment and sanitation sector and transported to Jiaozishan waste disposal site for sanitary landfill treatment. As a result, all generated solid wastes are properly treated and realize zero discharge, causing no pollution on environment. 4.2.3.5 Greening (1) Implement greening activities according to Green Standards of Urban Residents and Units in Jiangsu province (DB32/139-95). Plant shelter belts at the plant boundary and around pump stations and blowers. (2) Plant intensive chlorine-adaptability trees around chlorination room, such as yew, hemlock, holly and etc. (3) Use shrub and grass for isolation on ground green. Plant street trees on both sides of factory main road. Grow shrub, grass and flowers at other region and blank areas. Implement greening at the rest areas of plant except roads, buildings and constructers. Greening rate reaches 39%. 4.3 Pollution accidents emergency plan Implement the following emergency plans to nip accidents in the bud and realize the object of accident prevention. 4.3.1 Emergency action plan Constitute emergency action plan in case of chlorine leakage. Determine the specific activities depending on the degree of accidents. Each activity should be carried out by a 35 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan particular person in advance to ensure that action plan could be implemented quickly and smoothly in case of accidents. Main contents of emergency action plan are listed as following: (1) In case of chlorine leakage, quickly estimate the degree of accident, impacts scope, characteristic and extent on staff inside the factory, residents around the factory and surrounding environment. (2) Implement necessary accident control and mitigation measures. (3) Implement necessary protection measures on possible affected staff inside plant and residents around plant. (4) Provide emergency tools and facilities related with chlorine leakage accidents for local emergency service sector. (5) Staff from security department of waterworks and trained workers take on duty in turn. (6) Notify environmental protection monitoring sector to carry out follow-up monitoring on diffusion at downwind of chlorine leakage. 4.3.2 Leakage emergency plan in chlorination room Set up full-time safety staff, environmental protection staff in chlorination room and make full use of constituted accidents emergency plan to guide safe production. Suggest establishing emergency responding organization (leading group), which compose of waterworks director and leaders from production, safety and environmental protection department. In case of accidents, leading group takes charge of command of emergency rescue in chlorination room. Main contents are as following: (1) Send alarm once accidents break out. (2) Quickly find out source point, leakage part and reasons of accidents and control its development. (3) Waterworks leading group and rescue team should quickly arrive on site and make corresponding contingent decisions based on state of accident and degree of damage. (4) Leading group should organize vigilance on site and perambulation inspection and evacuation in the effected region if necessary; should organize rescue of the injured and 36 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan poisoned and indicate protection measures. (5) Leading group should organize relevant staff and accident-occurrence department to find out the cause of accident, bring forward accident control and elimination proposes, notify the local safety and fire-fighting sectors, and organize accidents temporary treatment. (6) Environmental protection monitoring staff should monitor accident site and diffusion district, organize equipment repair and accident treatment. After the treatment of accident, organize accident investigation group to investigate accident, summarize lessons and put precaution measures into effect. (7) After accident, based on the degree of impacts compensate the affected region and people according to national policies and restore the damage on the environment. 4.3.3 Leakage emergency plan of liquid chlorine steel bottles Based on the physical, chemical characteristics and toxicological features and latent accident risk analysis of main equipments, leakage emergency plan of liquid chlorine steel bottles is listed as following: (1) Quickly evacuate the staff of leakage contamination region to upwind and implement isolation, 150m for small leakage and 450m for big one. Strictly limit entrance and exit. If found anyone inhaled chlorine and poisoned, move him and lay him down at the place with fresh air, elevate his head, loosen his clothes and treat him with medicine or transported into hospital. (2) Emergency treatment staff should wear positive-pressure breathing apparatus and gas protective clothing. Try to cut down the leakage source. Leaking containers should be put away, repaired and reused after inspection. (3) Reasonably ventilate to increase diffusion and use spray water to dilute and dissolve. Should not use direct flow because that chlorine acts with water and generate hypochlorous acid and hydrochloric acid which are extremely caustic. (4) Construct dam or tunnel to receive generated wastewater. If possible, use pipe to introduce leakage into reducing agent (acid sulfate or acid sodium carbonate). (5) Ruptured chlorine bottles should be quickly put into neutralizing tank or be treated by 37 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan chlorine absorption devices. Leaking bottles should be soaked in lime emulsion. Leaking containers should be put away, repaired and reused after inspection. (6) Protection and control measures are listed as following: ① Respiratory protection: When the atmosphere chlorine concentration exceeds the standards, wear air respirator or oxygen breathing apparatus. In case of emergency rescue or evacuation, must wear oxygen breathing apparatus. ② Protection of eyes: covered by respiratory protection. ③ Protection of body: wear mask and rubber gas protective clothing. ④ Protection of hands: wear rubber gloves. ⑤ Other protections: It is forbidden to smoke, eat and drink on working site. After work, it is suggested to take a shower and change clothes. Keep good sanitation habitudes. Practices in the high-concentration district must be supervised. (7) First-aid measures are as follows: ① Contact with skins: put off contaminated clothes at once, flush by a great deal of water and go to hospital. ② Contact with eyes: lift eyelid, rinse eyes with flowing water and saline. ③ Inhalation: quickly get away from the site and arrive at the place with fresh air. In case of heartbeat stop, carry out artificial respiration and chest cardiac massage and then sent to the hospital. 4.3.4 Emergency plan of oil leakage At present, the Sheshan Oil wharf of Jiangsu Armed Police Corps is not completed. After completion, if oil leakage accident occurs, risk prevention measures and emergency plan proposed in wharf EIA report should be carried out immediately. The wharf owner should set up oil booms around the accident occurrence point and control the oil spillage in the range of water bodies encircled by oil booms. Longtan waterworks should set up an oil boom in 100m upstream of water intake to prevent impacts of oil spillage accident on water quality. At the same time, waterworks should assist wharf owner to initiate emergency plan, recover spilled oil and eliminate the residual on the water. Implementing the above measures, oil spillage 38 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan accident will cause small impacts on water quality of water intake. 4.3.5 Water contamination emergency plan of water intake Implementing the following emergency plan could ensure the least impacts on water quality in case of water contamination accident occurred at water intake. (1) In case of accidental contamination of water quality at water intake, stop water supply immediately. Enhance the water quality monitoring at water intake region and intake water after identifying that water quality attain the standards; if the contaminated water has entered waterworks through pipelines, increase drug adding quantity and capacity of back wash water. Distribute water until water quality attains the standards. (2) In the case that waterworks could not supply water for a long time because of contamination, contingent water supply should be carried out. Besides initiating emergency plan, contingent water source should be ready for normal supply of local citizens. At present, Nanjing Water Supply General Company has 4 waterworks in Jiangnan District and total water supply capacity is 1950000 m3/d. In 2005, the highest daily water supply capacity was 1280000 m3/d. Besides, there are 3 industrial self-supplies in Jiangnan District with the total capacity of 400000 m3/d. As the 3 self-supplies mainly provide water for industrial district whose water quality and management standards are not in compliance with urban water supply, water supply scope is gradually decreased and basically stop providing water for neighboring residents. Table 4.3.5-1 List of water supply situation in Jiangnan District Water quality Name of Capacity Water intake source protection waterworks (104 m3/d) object(2010) Yangtze River Jia Branch drinking Beihekou 120 water source, fishery water area II waterworks (right bank) Yangtze River Chengbei Shangyuanmen-Yanziji drinking 25 II waterworks water source, fishery water area (right bank) 39 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Yangtze River Shangyuanmen Shangyuanmen-Yanziji drinking 20 II waterworks water source, fishery water area (right bank) Yangtze River Jia Branch drinking Chengnan 30 water source, fishery water area II waterworks (right bank) Water intake of Chengbei waterworks locates in the Santaitong of the Yangtze River and water quality is excellent, which is the nearest from the construction project, so that it could be used as emergency water source. Water conveyance pipelines are under construction in Jiangnan district. There are water conveyance pipelines between construction project and Chengbei waterworks, so that Chengbei waterworks should supply water in case of outbreak of contamination accident in water intake of the project. 4.4 Environmental risk prevention and control measures Environmental risk accidents are unpredictable. However, except for some sudden accidents and natural damage, most of pollution accident could be prevented. Complying with certain principles and implementing necessary measures, the tragedy of pollution accidents could be avoided. The commonly-used 6 principles of accident prevention are: ① Accident prevention is the necessary part of realizing good management and ensuring production qualities in a enterprise; ② Management staff and operation staff must cooperate in the activities of accident prevention; ③ The head of the enterprise is the first responsible of safety who must act as a leader in organizing production activities; ④ Each post must have a definite safety guideline which is familiar to and acceptable by everyone on the post; ⑤ There must be an organization structure covered every aspect of safety and specific measures; ⑥ Try the best to obtain the latest safety production technologies and methods. The above six principles are related with a lot of key parts in the modern enterprise 40 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan management. Complying with these principles will have no doubt to minimize the possibilities and results in chlorination room to an acceptable level. 4.4.1 Chlorine leakage risk prevention and control measures 4.4.1.1 Chlorine storeroom and adding room safety measures Chlorine leakage accident is the biggest latent pollution source which would cause adverse impacts on environment. In this project, the following measures are carried out to ensure production safety. (1) Storeroom of chlorine is designed with consideration of natural ventilation; for the part where could not adopt natural ventilation, mechanical ventilation is used with frequency of 8-12 times/hour. (2) Besides using mechanical ventilation to keep clean of inner air, the storeroom is equipped with rescue instruments and effective protection apparatus, and installed gas leakage monitoring and alarm device. The installed position, quantity and method is compliance with Specifications for Design of Combustible Gas and Toxic Gas Detection and Alarm Systems in Petrochemical Industry (SH3063-1999). (3) Operating staff in the chlorination room must be strictly and specially trained and be employed until familiar with the detailed procedure of operating liquid chlorine steel bottles. Avoid varieties of leakage. No entrance for the indirect operating staff. (4) Chlorination room and storeroom should open outwards and be equipped with flexible locker for immediate evacuation in case of emergency. 4.4.1.2 Leakage protection and control measures of chlorine storeroom and adding room This project adopts neutralization and absorption devices to treat and control chlorine leakage. Implement the following measures to ensure that leak chlorine could not diffuse outside the room. In case of leakage accident, prompt alarm, neutralization and adsorption would greatly decrease impacts on environment. (1) Chlorination device is a vacuum adding machine which could make the pipes in the 41 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan state of vacuum. If the adding pipes are broken, chlorine would not leak in the air. (2) Equip chlorination room and storeroom with axial-flow blower to eliminate the possible leakage. (3) Install the leakage alarm, neutralizer and adsorption device in storeroom. When the concentration of chlorine inside the room exceed limited value, leakage monitor will automatically alarm and initiate absorption device which absorb and transfer the chlorine to neutralizer to react with caustic solution. In that way, the chlorine would not spill outside the room. (4) Place oxygen breathing apparatus and protective mask in the watch chamber of chlorination room in case of troubleshooting. 4.4.2 Oil leakage risk prevention and control measures (1) It is forbidden to construct and expand any project which could cause great risks on the water supply safety in the water source protection zone; the existing project should be planned to limit its expansion or transformed. (2) Install real time monitors for monitoring the water quality in the protection region, one at and the other at 500m upstream of the water intake. Once the water quality is accidentally contaminated, stop intake water and enhance monitoring activities. Intake water after identifying that water quality attains the standards; if the contaminated water has entered waterworks through pipelines, increase drug adding quantity and capacity of back wash water. Distribute water until water quality attains the standards. (3) Equip with a set of spillage intercept and recovery device, including oil boom, buoy, anchor, anchor rope, oil absorption felt, oil absorption machine and etc. (4) After completion of the planned Sheshan oil wharf of Jiangsu Armed Police Corps on the upstream, wharf owner should strictly implement the risk prevention and control measures and emergency plan proposed in EIA report. Trough strict management, prior prevention and prompt treatment, wharf owner should avoid pollution impacts of spillage accident on water intake downstream. 42 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan 4.5 Water-taking Reliability and Safety Analysis 4.5.1 Reliability Analysis of Water Quality The original planned scope of Longtan Water Resource Site is from Qixiang Estuary to its upstream for 2500m. The water intake for this project is located within the planned scope, where the water quality has always been protected. The project location is shown in the attached Figure 1. What will affect water quality safety is the quantity of influent pollutants. According to the investigation, there is no industrial wastewater outfall within the Class I protected zone of water resource. The influent pollutants are mainly from the branches and non-point pollution, which is finally reflected by the current water quality of river section. The scope of protected zone for the project is shown in the attached Figure 2. The monitoring of current water quality for wet and dry seasons has been respectively implemented for the project. The monitoring results show that the water quality in wet season is better than that in dry season. The water quality of Yangtze River is obviously better than that of inland rivers. The water quality monitoring results of Longtan section for Yangtze River show that, in the wet season, all the monitoring indicators could satisfy the Class 2 functional requirements for water bodies except that the SS monitoring results generally failed to meet the requirements. It indicates that the river section where the proposed project is located has relatively good water quality in wet season which could satisfy the requirements of defined water body function. In dry season, all the monitoring indicators could satisfy the Class 2 functional requirements for water bodies except ammonia and TP. The monitoring results of ammonia and TP can satisfy the requirements of Class III water quality standard. In general, the water quality for the river section at Nanjing plant site of Yangtze River generally maintains at Class II water quality level, and it is relatively stable within certain period at different cross-section, different distance from the banks and different water depth. The water quality in wet and dry seasons is also very similar. For some monitored cross-sections, the incompliance of SS, ammonia, BOD, TN and fecal coliform were found, which may be mainly due to busy ship traffic in the river section and the discharge of untreated domestic 43 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan wastewater. It is required to strengthen the regional monitoring and control of pollution sources, in particular, the centralized management and limitation of wastewater discharge activities in the tributaries joining Yangtze River within the regional water resource protected zone in order to implement the control measures of total amount control and compliant discharge of pollution sources. For the upstream docks, the accident risk prevention measures and emergency action plan should be established and implemented to ensure the water quality in the area could meet the Class II standard of “Environmental Quality Standard for Surface Water�(GB3838-2002). The water quality for Nanjing section of Yangtze River near the water resource is good. The monitoring shows that all the indicators for the river section near water intake for the project generally comply with the Class II standard of “Environmental Quality Standard of Surface Water� (GB3838-2002) and also the water quality standard for surface water used as centralized drinking water sources. Therefore, the water quality of Yangtze River can generally meet the water taking requirements of the project. 4.5.2 Reliability Analysis of Water Quantity According to the conclusions of water resource justification in the “Water Resource Justification Report for Phase I of Nanjing Municipal Longtan Water Treatment Plant� (by Hohai University), the rationality analysis for project water taking activity is as follows: The water taking flow rate in 2010 for Phase I of the project is 400000m3/d, and that in 2020 for Phase II is 800,000m3/d. According to the statistic results in Section 3.2 of the EIA report, the annual water taking quantity along Yangtze River in Nanjing Municipality is totally 3.197billion m3 with the average water taking flow rate of 101.38m3/s. (1) Analysis of minimum annual flow rate According to the statistic data of Datong Hydrology Station from 1950 until 2005, the historical minimum flow rate is 4620m3/s (Jan. 1979). The frequency analysis was carried out based on the historical minimum flow rate. When P=99%, the corresponding flow rate is 5050m3/s. Without considering the influent within the river section and with the deduction of water taking flow rate within the section, the flow rate for the main stream of Yangtze River 44 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan passing the water intake for the project is 4958.6m3/s; in relation to the maximum water taking flow rate of 800,000m3/d for the project, i.e., 9.26m3/s, there is high margin. That means sufficient water taking guarantee rate can still be maintained for the project even with the minimum flow rate of Yangtze River in dry season. (2) Analysis of minimum annual runoff Without considering the influent within the river section, the annual minimum runoff at Datong Hydrology Station is 675billion m3. At the frequency of P=99%, the corresponding annual runoff is 639billion m3. The maximum annual water taking quantity of the project is 0.292billion m3. Even in the driest year, the water taking quantity of the project only accounts for its 0.045%. With the deduction of total actual annual water taking quantity in the river section, it only accounts for 0.05% of the runoff in the driest year. Therefore, the water quantity of Yangtze River can satisfy the water taking requirements of proposed project. In general, the water taking quantity of the project can be sufficiently guaranteed. 4.5.3 Analysis of Ecological Impacts (1) Impacts on water ecosystem The construction of water intake will increase the SS concentration in part of the water body, affect the habitat of fishes and result in adverse impacts on aquatic organisms. During construction, the scope of activities for fishes will temporarily decrease. The involved river section is about 2200m wide, and the head of water intake is 240m away from the river embankment. The river section related to the underwater construction activities is about 200m wide, only accounting for 9% in the total width of river section. Therefore, the impacts on the migration passage of aquatic organisms such as fish are minor. If the construction is scheduled in winter, then the spawning and migration period of aquatic organisms such as fish can be avoided. With the project completion, the head of water intake will be about 200m into the river. Except for the head of water intake, fish can still pass over the pipe; therefore, there is minor impact on fish due to the relative decrease of river cross-section. None of the domestic wastewater and production wastewater from the project is discharged 45 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan into Yangtze River; therefore, there will be no impact on the water ecosystem. (2) Impacts on terrestrial ecosystem The project construction will lead to the loss of partial terrestrial ecosystem, which mainly includes about 275mu bottomland and pools within the river embankment dominated by reeds that will be turned into the WTP site. In the latter phase of project construction, greening works and protection zones will be implemented, which is mainly to enable the sufficient greening at the boundaries of plant site and auxiliary areas for production and living. The greening area will be 71500m2 with the greening rate up to 39%. Therefore, the loss of terrestrial ecosystem resulting from the project will be restored to the maximum extent. 46 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan 5.

Information Disclosure 5.1 Online information disclosure According to the relevant regulations of Interim Methods of Environment Impacts Evaluation Public Participation (Huanfa [2006] No.28), environment evaluation unit carried out two rounds of information disclosure, in October and December 2007, about environment impacts of first phase of Nanjing Longtan Water Supply Project on the website of Nanjing Water Supply General Company (http:// www.jlwater.com) (webpage snapshots are shown in Figure 1 and Figure 2) to consult the public’s opinions. There has been no negative feedback received during information disclosure. The environmental management plan is planned to be disclosed on the website of Nanjing Water Group Corporate during Aug. 1st~10th, 2013. 89 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Figure 1 Snapshot of 1st online information disclosure 90 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Figure 2 2nd online information disclosure 5.2 Information disclosure on newspaper At the late stage of environment impacts evaluation process, environment impacts assessment report and environment management plan were placed in Xihua village community residents’ committee for the public to examine and read. Publicity in the newspaper was employed in Nanjing Morning Newspaper in April 14, 2012 in order to make the public understand project environment impacts evaluation progress and provide valuable suggestions, to inform the public check environment evaluation documents in Xihua village community residents’ committee or environment evaluation unit. Contents of information disclosure in the newspaper is shown in Figure 3. 91 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Figure 9-3 Copy of Notification on Project EIA Information Disclosure on the Newspaper of Nanjing Morning 6 Conclusions of public consultation The results of public participation show that: (1) Subjects to the survey were distributed extensively, which had an extensive representation in ages and education levels. Most of the surveyed is the public and staff of enterprises around the planned project, who will be directly affected by the project and know better about local environmental and social backgrounds and whose suggestions and comments could well reflect public opinions in the region and be representative. (2) Individuals and units around the project are with supportive attitude in general and concerns about the impacts caused by the project. So that, based on the protection of planned construction areas, environment evaluation unit must demonstrate feasibilities of project construction from scientific point of view and propose constructive suggestions to mitigate local environment impacts to the minimum. (3) Residents worried about noise, wastewater and exhaust gas problems during construction period and commonly suggested that construction unit could reasonably schedule, put every environmental protection into effect and try the best to reduce the inconvenience of 92 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan noise, exhaust gas and wastewater pollution. (4) Relevant departments should enhance strength of publicity of project environmental protection, to make the public in the affected areas further understand environmental protection measures so as to more positively support project construction. 93 400 000 m3/d Longtan Water Treatment Plant Project (Phase I) Environment Management Plan Project Location Project Location 94 Chu River 河 河 � � San 三 三 Jiang Jing'an River � � 安 安 河 河 River 河 河 江 江 Dadao River Project Location � � 龙潭镇�水� 项目�置 民 民 大 大 Water Intake of Longtan Town 河 河 便 便 Bianmin River Longtan Water Source Protection Zone �护 �� 护区 区 河 河 龙潭 龙 水� 潭水 河 河 民 民 便 便 Bianmin River 江��野田水 泥厂�水� 七 七 Water Intake of Jiangnan Xiaoyetian Cement Plant 油�公� 乡 乡 Jiu � � �水� Water Intake of Oil Transportation Co.
