Background The Tai basin includes part of the three provinces of Jiangsu, Zhejiang and Anhui and Shanghai Municipality, with a total area of 36,500 square kilometers, of which 52.5% is in Jiangsu Province, 33.4% in Zhejiang Province, 13.5% in Shanghai and 0.1% in Anhui Province. There are 37 large and medium sized cities and county level cities in the basin. At the end of 2000, the total population of Tai Lake basin was 36 million, its urbanization rate reached 51%, with a GDP of USD 121 billion. Although the area of Tai Lake basin is only 0.4% of the total of the China, its population accounts for 3% and GDP for 11% of the total in China. This region is one ofthe most active ones in economic and social development in China. With the rapid economic development, sharp increase of population and speeding up of urbanization, large amount of wastewater is being discharged into rivers and lakes without treatment, severely worsening the water quality in Tai Lake. In July 1990, blue algae spread quickly in Tai Lake, and no water could be taken by Meiyuan Water Plant, forcing 116 industrial enterprises in Wuxi to stop production, resulting in direct economic losses of 160 million RMB. At present in some areas along the shore of Tai Lake, nutrients such as nitrogen and phosphors have far exceeded the specified standard values. The water could no longer be used as a source of water supply. Pollution to the water in Tai Lake has become a restricting factor to the sustainable economic and social development in the region. The deterioration and eutrophication in the water quality of Tai Lake has attracted high attention from the Party and State. Starting from 1996, the state listed Tai Lake among the key projects for water pollution rehabilitation for the "three rivers and three lakes" of the China. In 1996, the State Council set up the leading group on Tai Lake water resources, and a implementation plan was formulated to prevent the water pollution and rehabilitate in Tai Lake in two phases. The governments at all levels of Jiangsu Province have also attached great importance to the prevention of water pollution and the rehabilitation in Tai Lake, and the Implementationprogramfor the prevention ofwaterpollution andthe rehabilitationin TaiLake ofJiangsuProvincefor the "Tenth Five-yearPlan" was proposed. The objectives of this program include building a series of WWTPs, dredging and rehabilitation of rivers and lakes, and some project to readjust and control water (by diverting, making-up and stopping wastewater), for the propose of protecting the water quality in Meiliang Lake and Wuli Lake. The program also sets the goal that the permanganate index at the main potable water sources of Tai Lake and in the water of main inflow and outflow rivers of the lake will meet the Class III standard for surface water, the total phosphor be lowered as compared with that in 2000, and the river network water quality in the central urban areas of Suzhou meets the landscaping requirements. As the domestic capital supply is not sufficient, the Jiangsu Province government proposed to use World Bank loans to speed up the project construction and to complete the comprehensive rehabilitation projects for the water environment in Tai Lake basin in South Jiangsu. 2. Project composition and investment The proposed World Bank loan project consists ofthe following 9 components: (1) Wuxi Wuli Lake rehabilitation component; (2) Wuxi wastewater treatment components: including three WWTPs at Huishan, Dongting and Anzhen; (3) River network dredging component in central urban area of Suzhou; (4) Wastewater stopping component on Xujiang River and Shangtang River in Suzhou: polluted water controls to be built respectively on Xujiang River and Shangtang River at the intersections with the Grand Canal; (5) Suzhou wastewater treatment components: including three WWTPs at Loujiang, Fuxing and Wuzhong. The project components with their main contents ofwork and investment are detailed in Table 2-1, and their locations are shown in Figure 2-1.  Table 2-1 Composition and investment of the Project Unit: million RMB Area Component Main contents Local rld Total investment bank loan investment Polluted water control, embankment Wuli Lake Rehabilitation rehabilitation and ecological 116.021 92.099 208.12 restoration Phase I of Huishan WWTP with capacity of 25,000 m3/d and 73.001 70.049 143.05 Wuxi sewerage networks ..^.WWVTPs and sewerage .

Briefs of environmental impact 3.1 Beneficial areas of the Project The implementation ofthe project will effectively improve the water environment in Suzhou and Wuxi. give a powerful impetus to the economic development, and realize the sustainable development in these two cities. (1) Environmental benefits Wastewater will be conveyed to various WWTPs via a fairly complete collecting system, and be treated to meet the standards before being discharged into the receiving water body. After the implementation of the project, except the effluent receiving water body, the river network at the Project area, as well as Grand Canal sections in Wuxi and Suzhou and Tai lake would see water quality improvement following the operation of the six Project WWTPs. More specifically, at 2010 when all six WWTPs are in operation, the below Class V river length will be reduced from the current level of 16% to 11.5%, while Category IV will increase from the current 30.9% to 33.6% and Category III from 1.9% to 3.7%. As these rivers are one of the major pollution sources to the Tai lake (the other being agricultural and area sources), the improvement of river water quality will result in improvement of the lake water quality. 2  /tK 0 ~~~~Figure 2-1 The Locations for Components ofTBUEP SSwIuwi WtsL*=wion hfogProvi- Jr{ l t;----< / ~~~~~~~~~~~~~~Shandong ' 5- - - tf t/ \ ''~~~~~~~~~~~~~~~~~~~~nt 0 ~~~~~~~~Anhui Jiangsu - n L 5 p t4a4*,;.e 4R/i l --~~~~~~~~~~~~~~~~~~~k~~W;> --t Shanghai iE~Zhnling > 0 1 x ,,iM d~~~~~~~~~~N'Aing 2i t *2= > |WffCn4 1 + iil. ! ) v S -~~~~~~~~~~~~~~~~~~~~~~~~~~~ S~hanpgha _u C z City , . - . ,>i < - _r [~~~~~~~~N, -\: . ,1Lake nr ~~~~~~~ider Con>: ..

If all WWTPs in the region are built as planned, up to 70-80% of the pollutants currently discharged to the lake would be intercepted and removed. The entire Tai lake would be benefit from reduced TP, TN and BOD, with north part of the lake which are among the worst polluted benefit the most. The Project will reduce a total of COD load by 128.5 tons per day, TP loads by 0.5 tons per day and NH3-N load by 6 tons per day by the six WWTPs. These reduction will contribute to achieving master plan targets (pollutant discharge loads and surface water quality). Other additional potential benefits to bebrought by the Project include: * Recovered ecosystem in the TLB area, helping restoration of aquatic life and increasing of bio-diversity; * Reduced pollution to crops irrigated currently by polluted water and increased agricultural and aquacultural yields and productivity; * Increased property values for land and real estate of lakeshore and river side areas; * Improved environmental infrastructure for sustained economic developments and attracting outside investments; * Improved recreation and environmental aesthetics ofthe communities ofthe project area; and * Increased revenues from tourism. (2) Social benefits The social benefits will be significant. In particular, there are a large number of residents living virtually on the dredging rivers (with their houses as the bank and their back windows open on the rivers). The cleaned riverbeds are expected to reduce the nuisance odor in the summer, enhance the hygiene and sanitation of their "backyard", the rivers, increase the value of their properties, and improve the environment in which they live. (3) Economic benefits After implementation of the project, the water environment in the ancient city of Suzhou and Wuxi will get substantially improved. This will give a powerful impetus to the development of tourism, help to create a good investment environment, to attract more investment, thus promoting the rapid economic growth in Wuxi and Suzhou as a whole. 3.2 Impact areas of the Project They include areas along Tai Lake, especially the urban areas of Wuxi and Suzhou, Wuzhong Economic Development Zone, Huishan District, Xishan District and Wuli Lake ofWuxi. 3.3 Environmental impact during construction period The construction work activities for WWTPs in cities, the river network dredging in Suzhou and Wuli Lake rehabilitation may produce the following adverse impact. 3.3.1 Pollution of flying dust It will mainlv be caused by soil excavation, materials mixing, running vehicles for construction, spoil piling areas and improper management of construction materials. The Class 11 standard may be exceeded within 80-120m leeward from the work site road, 100-150m of the spoil area, and within 30-60m from the road for transporting the spoil. Therefore, the impact to local residents will be limited within 15Gm. Work transport will be limited to within l00m on both sides ofthe work line. 3.3.2 Odor pollution from sediment dredging 3  This will mainly be caused by the odor from dredging. The main constituents of such gas are NH3 and H2S, and they will gather in high concentration within 150 from the work site. The residential areas that will be affected by odor include those along Shangtang River and Shantang River, Fuxing residential quarter and Youlian New Village. 3.3.3 Noise It will mainly come from the construction machinery and running vehicles. Piling machines can produce a noise up to 1 OdB (A), and it can be heard at a far distance in open area, affecting the life in the nearby towns and residents, especially the first row of houses facing the work site. In day time, the value exceeding the limit for construction machinery is within 50m, while in night, the noise limit value can be met at 200m. 3.3.4 Construction wastewater Construction activities will cause pollution to surface water. The construction wastewater includes the domestic wastewater from construction workforce, and water for cleaning and rinsing construction machinery. The water flow will not be great, but it contains large amount of sediment and oil, and organic pollutant. Construction wastewater must be treated before discharge. 3.3.5 Sediment disposal All of sediment monitoring parameters of Suzhou River Network Dredging component can meet Pollutants Limits for Sludge Agricultural Standard described in "Discharge Standard of Pollutants for Municipal WWTP (GB18918-2002)" except Pb of Xiaomiduqiao River. The leaching test shows that heavy metals of sediment leachate do not exceed Standard Values of Extraction Procedure Toxicity described in "Identification Standard for Hazardous Wastes-Identification for Extraction Procedure Toxicity (GB 5085.3-1996)" and is not hazardous matter. Therefore, it would be unnecessary to be disposed of at hazardous wastes landfill. Furthermore, as the pollution of dredged sediment was mainly formed by receiving municipal wastewater from both domestic and industrial sources, it could not be categorized as industrial solid waste and would not be necessary to be disposed of in a way of industrial solid wastes disposal site. The sediment from dredged rivers in Suzhou will be disposed of in the Sanjiaozui fish ponds to the north of Shanghai-Nanjing Expressway and east of Shiziyang River, see Figure 3-1 for the location of the site. This is a temporary sediment disposal site, covering an area of 786.6 mu and will become greening land in the future. There are no sensitive receptors within the range of 500m of the site and no faults and fracture zones. The surface elevation (4.5 m) of the site exceeds flood protection standard once per 100 years (5.5 m) of this area, and the site has a good clay and mild clay layer with a thickness of about 3.5 m and a permeation coefficient less than 10 7 cm/s will do little impact on groundwater. The siting can meet relevant Chinese enviromnental protection regulations. Leaching test does not show dredged sediment is hazardous matter, but the segment at Xiaomiduqiao River will not be dredged for the time being for the sake of safety. The potential environmental impact of sediment piling is from tailing liquid as ordinary organic wastewater on surrounding fishponds and groundwater. The vertically and horizontally impervious measures will be taken. 3.3.6 Urban traffic The sediment dredged from canal network in Suzhou will be transported in 2-4 barges of 40t/60t to Sanjiaozui sediment disposal site near Shiziyang River, in five routes of Shangtang River, Xujiang River, Dalonggang, Waicheng River and Yuanhetang. As Shangtang River, Xujiang River and Waicheng River have been planned as landscaping rivers for touring and no freight ships is admitted to Waicheng River, therefore dredging will have very little impact to the transport in these three rivers. Transport activities are only carried out in Yuanhetang (Navigation level Grade V) and Dalonggang (Navigation level Grade VI), and during dredging, more boats will be used or part of the navigation channels will be taken, making the navigation channel narrower and producing local pressure on normal shipping. 4  -Figure 3-1 The Location of sanjiaozuid Efflt disdarge Sedimant disposal site * c~~A-, st F''X/''-1   Around Wuli Lake in Wuxi, fairly concentrated transport is located at Maligang, Changguangxi and Caowangjing. Water flow may be interrupted or the navigation channel be narrowed during the works, and this will produce some impact to the transport in the above navigation channels. During the construction period, laying the wastewater pipelines will increase the traffic congestion to the already crowded streets, and produce impact to normal transport and traffic. 3.3.7 Impact on scenery and historical relics The flying dust caused by transport of construction materials and sediment may produce certain impact to cultural and historical relics close to the transport route, and also affect their tourist value. 3.3.8 Impact on public health There will be large number of construction workforce on the work sites, where the sanitation conditions will be relatively poor. This plus a high density of people may provide propagation routes for various epidemic diseases. A work site is a potential place of spreading and eruption of diseases, and mainly the construction workforce will be affected. In view of this, attention will be paid to the sanitation and epidemic prevention work on work sites. Construction workforce will go through physical examination before entering the site and also periodical examinations during the works, to safeguard their health. The propagation and education on sanitation and epidemic prevention will be enhanced on work sites to build up the awareness of self-prevention by construction workforce and do a good job in sanitation and epidemic prevention on site. Management regulations on sanitation will be worked out for the site, inspections on the sanitation conditions on site will be strengthened, and attention will be paid to food hygiene and environmental sanitation on site. 3.3.9 Impact of wastewater collection system The wastewater collection systems in Huishan, Anzhen and Wuzhong sewer network services are mostly to be constructed on the green field, together with road and other infrastructure. Main impact will be airborne dust but the areas will have been mostly leveled and under development with minimum sensitive receptors. In other sewer service areas, sewer lines are needed to construct, at least partially, in urban built up areas. Main impacts will be block of urban traffic, airborne dust during excavation, noise from machinery, outing and convenience of local residents and construction safety to the general public. 3.4 Environmental impact during operation period 3.4.1 Impact on water environment * Impact of effluent discharges from WWTPs to receiving water bodies Effluent from WWTPs will produce pollution zone under the normal conditions, but the impact is acceptable. Due to Wuyu River which diverts water from Yangtze river to Tai Lake Basin at the downstream from receiving water body of Dongting and Anzhen WWTPs, there will be substantial impacts on Wuyu river under the emergency conditions, therefore accidental discharges will be avoided and management will be strengthened. The possible affected enterprises will be informed in time about water quality of receiving water body once accidental discharge happens. * Impact ofWuli Lake polluted water control ofWuxi on water environment The simulation calculation results for Wuli Lake polluted water control show that, with low water level condition, the water quality in some surrounding areas will deteriorate slightly. After completion of the gate, the COD4,1 content in Xiaoyugang, Ludian Qiaobang and Lixi River will increase by 0.1-0. 8mg/i, and the impact in other rivers will not be obvious. As the pollutant to the receiving water bodies will increase by a limited amount, the impact of this project to the surrounding area water quality is acceptable by the pollution interception by the Binhuxincheng WWTP in the southeast of Wuli lake and the water level regulation and control ofWuli Lake. 5  * Impact of wastewater stopping project in Suzhou to water environment As the incoming wastewater from the upstream canal is put under control, the wastewater stopping project will achieve some improvement to the water quality in the rivers after its completion. 3.4.2 Impact on ambient air environment The odor from WWTPs and pumping stations will mainly from the screens and primary sedimentation tanks, and sludge disposal and transport will also produce odor. Its main constituents are NH3, H2S and methyl sulfides. In the environmental assessment, the atmospheric diffusion model was used to calculate the sanitation protection distance. The results show that under normal meteorological conditions, the distance to reach the residential area standards varies from about 100 m from the WWTP in Wuzhong up to 350 m in Fuxin. Within these distances, there is no residential or other sensitive receptor surrounding the WWTPs, except Loujiang WWTP which combing another industrial source at the same site, the odor is expected to exceed the standard. 3.4.3 Impact on noise environment The main sources of noise from WWTPs during operation are the lifting pumps, sludge pumps, air compressors, and submerged pumps in the pumping stations. The source intensity of noise from WWTPs is 90-95dB (A) and that of a pumping station is 70-81dB (A). According to the noise prediction and calculation, the standard will be exceeded at the plant boundary during night at Huishan and Loujiang plants, and during both daytime and night at Fuxing plant due to the 3 WWTPs locate in main lines of communication such as road, channel and railway, the background value exceed standard. In other plants, the limit is met standard at the plant boundary. Suzhou has designated Shangtang River and Xujiang River as the special channels for tourist boats, and access by other ships is not permissible. During the operation period of the ship lock, the main noise source will be the tourist boats, with the maximum value being 80-9OdB (A). The prediction result is that, with a boat source intensity of 80dB (A), the limit value will not be exceeded for residential quarters around ship locks at Xujiang River and Shangtang River during either daytime or night, with a boat source intensity of 90dB (A), the limit value will not be exceeded for residential quarters around ship locks at Shangtang River during either daytime or night, but it will be exceeded slightly for residential quarters around Xujiang River ship lock. Therefore, the tourist boats will not operate during night. 3.4.4 Impact from sludge of WWTPs The total sludge amount generated from Suzhou and Wuxi WWTPs are 226 and 111.1 m3/d respectively, with a water content about 65%. Leaching test will be done within first 3 months after WWTP operating regularly. If sludge is found to be hazardous matter, it will be disposed at hazardous wastes landfill (in accord with GB18598-2001) which will be built by the end of 2006 in accordance with the document (Suhuanji[2002] No.18) issued by Development and Planning Commission of Jiangsu Province, otherwise, it will be disposed of at Qizishan landfill in Suzhou and Taohuashan landfill in Wuxi. Sludge hauling is a potential environmental concern. Potential leaking, odors as well as heavy traffic of hauling trucks themselves would affect the environment and residents along the hauling routes. Ring roads other than roads passing through the city centers have been designated for sludge transportation, to avoid heavily populated areas or business districts and rush hours. Especially, water-tight hauling trucks will be used to avoid odors and leaking from contaminating the hauling routes. Transportation time is arranged at 4-6 a.m. and 7-10 p.m. to avoid rush hours. Qizishan and Taohuashan landfill are both designed in accordance with design and environmental protection standards of domestic wastes landfill with capacity of 4.7 and 4.26 million m3 , and there are no residential areas and scenic spots within 500 m. The sites are covered up by soil with thickness of 20-30 cm everyday to relieve odor impact. Leachate of the sites is collected and conveyed to WWTPs, and then discharged into rivers after treatment. According to capacity of the two sites and sludge amounts of WWTPs, the operational life of Qizishan and Taohuashan landfill will be shortened about 1.5 and 2 years respectively. This factor has been taken into account while local governments plan to build new 6  landfill. 3.4.5 Impact on landscape Shangtang River ship lock is close to the tourist zone of Hanshan Temple at a distance of 230m, between Jiangfeng Bridge and Laifeng Bridge. The ship lock layout will keep the original style of the scenic zone of Hanshan Temple with ancient buildings, and create the water town features of small bridges with running waters. The working gates for both inner and outer heads will be transversal type, and the buildings for the headstock gears, control room and the management zone will be in an ancient architectural style to harmonize with the water town landscape of small bridge with running waters. The ship lock of Shangtang River will add a scenic spot for the tourist zone of Hanshan Temple. For Xujiang River hub, to prevent erosion to Caiyun Bridge and the ancient post of Hengtang (historical relics), revetment will be made for the river banks from the gate toCaiyun Bridge. 3.4.6 Relocation and social and economic impact The total land acquisition of The Project is 9082.59 mu, permanent and temporary land acquisition account for 10% (908.42 mu) and 5% (456.33 mu) respectively. Construction of the component will lead to change in the existing functions ofthe land and damage of some vegetation resources, causing loss of water and soil to some extent. In addition, The Project will affect the normal order of life, study and production of the local residents and people affected is 3158. Residents have to relocate will be provided with houses by the government or be paid in cash for compensation. The rate of compensation will be determined according to the quality and location of the houses involved, and relocation allowance and allowance for ancillary facilities will be taken into unified consideration. Proper form of compensation will be made so that the life of the relocated residents will not be affected. 4. Mitigation measures of impact on environment 4.1 Overall mitigation measures 4.1.1 Design phase * All project sites will be carefully selected to avoid or minimize potential impacts to the environment. * All WWTP plant layouts will be arranged in such a way that it would minimize the impacts to the surrounding sensitive receptors particularly for Anzhen and Loujiang WWTPs with villages and guess house nearby. * The shiplock and sluice gates will be designed to harmonized with the local architectural style. * All the mitigation measures will be incorporated in the engineering designs. 4.1.2 Construction period The proponents will sign contracts with construction units. Environmental protection measures will be defined as construction activities in contracts and implemented by construction units during construction period. The corresponding mitigation measures have been promoted according to local environmental situation. * Construction sites, transportation routes and materials handling sites will be water sprayed in dry and winding days up to 2 times a day, especially if these sites are near sensitive receptors, such as villages and residential areas. * Construction activities will be scheduled carefully to minimize the impact of noise from construction machinery to the surrounding environment. Night time uses of certain noisy machines 7  such as excavators/dredgers and concrete vibrators, etc. will be prohibited. * Any chance finds of cultural relics during construction will be preserved/protected and reported to the authority for further evaluation and proper handling before resuming construction activities * Sewrage and other waste from construction camps in rural areas will be collected and diverted to municipal systems to avoid contamination ofthe surrounding areas. * Temporary land occupation, particularly in the farm land, will be planned well ahead of the construction in consultation with the farmers and others affected to minimize the loss of crops. At the end of the temporary uses, the land will be re-stored to its original state. * The sediment disposal site has clay layer at bottom. This base will be compacted during site preparation to further reduce it infiltration ability. A settling tank will be included in the design for SS removal. * All sludge barges will be banned to operate at night. Those which do not meet environmental standard (motor oil leaking, barge body leaks, excessive motor noise, etc.) will not be retained for sediment shipping. * Sanitary and anti-epidemic affair will be emphasized. Construction workforce will go through physical examination before entering the site and also periodical examinations during the works, to safeguard their health. The publicizing and education on sanitation and epidemic prevention will be enhanced on work sites to build up the awareness of self-prevention by construction workforce and do a good job in sanitation and epidemic prevention on site. Management regulations on sanitation will be worked out for the site, inspections on the sanitation conditions on site will be strengthened, and attention will be paid to food hygiene and environmental sanitation on site. 4.1.3 Operation period Proper measures will be adopted to reduce environmental impact and improve environmental benefits. The adverse impacts during operation period are odor, noise and wastewater of WWTPs and effluent of sediment disposal site. The corresponding mitigation measures have been promoted according to local environmental, economic and technical situation. * Properly follow the operation procedures and ensure plants and sludge disposal facilities operational as designed, to ensure treatment efficiency, to properly handle the sludge and to minimize the generation and emission of odors. * Sludge generated from the WWTPs will be tested by the leaching test procedure to determine whether it is hazardous waste, within the 3 months of the WWTP operation. If it is, the sludge will be diverted to the hazardous waste disposal center to be built in 2006 in both Wuxi and Suzhou, instead ofthe municipal solid waste landfills, under the current plan. * Develop contingency plans for power failure, overflows, equipment malfunctioning and other conditions which may affect the proper functioning of the WWTPs resulting in discharge of raw wastewater into the receiving environment. * Noisy equipment and machinery will be regularly maintained to be in good conditions to avoid excessive noise. * Maintain good housekeeping at the WWTPs and other Project facilities and minimize impacts to the surrounding communities. * Maintain regular consultation with the residents in the nearby communities and respond promptly any concerns they may raise with regard to the operations of the wastewater, pumping station and sludge handling and disposal facilities. 8  4.2 Pollution mitigation measures for environmental rehabilitation components in Suzhou 4.2.1 Mitigation measures for polluted water control component of Suzhou The pollution mitigation measures for the polluted water control in Suzhou during construction and operation periods are shown in Tables 4-1 and 4-2.

The operation conditions will be adjusted according to seasonal requirements, to ensure normal operation. Therefore, the influent and effluent must be monitored frequently and regularly. Samples shall be taken every two hours, and then the mixed samples during the day shall be analyzed. The analysis parameters shall include: pH, CODCr, BOD5, DO, NH3-N, TN, TP, SS. (2) Ambient air and noise monitoring According to the features of the project, the odor amount emit from aeration tanks is small. It may affect the air quality ofthe plant. Ambient air monitoring will be done for 1or 2 days in each season, respectively in the morning and afternoon. Noise monitoring will be measured in day and night time (6-10 a.m. and 10 p.m.-6 a.m.) last 15 minutes when high noise is produced. (3) Main equipment and instruments The main equipment and instruments are listed in Table 5-11. 36  Table 5-11 List of main monitoring instruments No. Description Quantity Application I Water quality sampler 4 sets Water sampling 2 Atomic absorption spectrophotometer 1 Determination of metallic elements 3 Magnetic agitator I Agitation 4 Oven (with blowing device) I Determination of SS, etc. 5 BOD incubator 1 Determination of BOD5 6 High pressure pot 1 Determination of TP, TN and disinfection 7 Spectrophotometer 1 Colorimetric analysis 8 Acidity meter I Determination ofpH 9 Dissolved oxygen tester 1 Determination of dissolved oxygen 10 Electronic balance (0.0001 g) 1 Weighing 11 Biological microscope I Biological phase observation 12 Refrigerator I Preserve water samples and reagents 13 Centrifugal machine 1 Separation of samples and Determination of TN 14 Vacuum pump 1 Filtering 15 Electric oven 1 Heating and preparation of reagents 16 COD tester I Determination of COD 17 Culture box 1 Bacteria culture 5.5 Supplementary monitoring plan during construction period Supplementary monitoring plan will be carried out to make up for above monitoring plan, see Table 5-12 for details. The contractors will record monitoring data everyday and submit a monitoring report every month and a conclusion report every year to supervision unit in order to find and correct problems in time.

Environmental management and monitoring costs are divided into three levels due to the scales and impact scopes of 6WWTPs are different. Anzhen and Wuzhong WWTP (20,000-25,000 m3/d) need 160,000 RMB, Huishan and Dongting WWTP (50,000 m3/d) need 180,000 RMB, Loujiang and Fuxing WWTP (>100,000 m3/d) need 200,000 RMB, adding up to 1,080,000 RMB. The cost of 9 components amounts to 1,546,000 RMB. 7. Staff training program Wastewater treatment scheme is important to environment improvement and gains the support from the WB. So the environmental protection will be consistent with international standards. After construction of the project, the local environment will be improved. In order to ensure successful construction and operation of this project, the staff will have strong environmental protection acknowledge and skill. These staff engaging in management of WWTP and construction will receive further training so that the environmental protection measures can be carried out actually. The proposed training methods: domestic training and overseas training, which will be preferred, based on requirements for management levels and working positions. staff training include following aspects: * Environmental laws and regulations: Domestic Environmental Protection Law(EPL) and constituents; Safeguard Policies of World Bank; Legal responsibility of EPL, Environmental Protection Regulation for Construction Project; Local(Tai basin) environmental protection laws and regulations; * Environmental monitoring: Environmental monitoring method; water, ambient air and organism sampling and analysis rules; Environmental parameters analysis methods; * Wastewater treatment technology: Wastewater treatment principles, processes and methods: technologies maintaining nonnal operation of WWTPs; * Sludge control and disposal: Technologies of sludge landfill; Management methods, Safeguards and environmental protection of Sediment disposal site; Treatment methods of leachate and methane; * Environmental accident and emergency disposal: Mechanics of incipient fault; Preventive measures and methods; Emergency disposal methods; * Public participation and communication: Public participation and methods and procedures; Importance ofpublic participation, and * Pollution control and management: Construction flow and pollution producing points; pollution control methods and management measures during construction period.
