3.1 Projects introduction 3.1.1 Project background Bengbu City is located northeast of Anhui Province and situated at the middle part of Huaihe River. It is a key city of processing industry, the business and center of the science and technology in Northern Anhui area in Anhui Province. Because it is located at the special position, at the cross of the Jin-Pu Railroad main line and Huaihe River, it is also the key position for aquatic and land transportation in Northern Anhui, and thus is regarded as the first port along Huaihe River. There are many inland rivers and lakes in Bengbu City, while the city is relatively lack of flood prevention facilities. So some part of the city is seriously submerges, big water logging when heavy rain, small water logging when light rain. Life and security of the citizens in the city cannot be effectively safeguarded. This has been affecting people’s ordinary life and the industry and agriculture production. Along with the development of urban economy and the increasing improvement of the people living level, the residents have paid more and more attention to the quality of life and the city ecological environment. But the present environment problems in Bengbu mainly are: the flood control standard is low, the flood disaster is frequent; the civil and the industrial sewage increase year by year, the necessary facility for the sewage collection, processing and so on is extremely insufficiency. This has not only restricted Bengbu’s sustainable development, but also had the extremely adverse consequences to ecological environment of Bengbu section region in the Huaihe River Valley. In order to realize the improvement and the comprehensive promotion of Bengbu inhabitant survival environment and the city overall ecological environment, it is the most important thing for the Bengbu social economy development to improve the city necessary infrastructure construction level and to enlarge to flood prevention and environment integrated improvement of Huaihe River and the city inland rivers and lakes when controlling strictly each kind of pollution at the same time. 3.1.2 Construction projects introduction The Bengbu Municipal Party Committee and City Government propose to improve further the construction facility of the city flood prevention and the ecological environment. They plan to use the World Bank loan to carry on the construction program of “Comprehensive Project of Bengbu floods prevention, the infrastructure and the ecological environment”. The entire project divides into 8 sub- project programs, involving four categories, the flood prevention and water logging governing project, the city ecological environment comprehensive programs such as silt clearing and improvement of the rivers and lakes, the vegetation restoring of the coast etc., the project of infrastructure integrated systems for city rain and wastewater network, and the project of water supply and the sewage treatment. The project construction scope covers the Bengbu urban district and three county regions including Huaiyuan, Guzhen, Wuhe with the total investment approximately 1,660,000,000 Yuan. The eight sub-projects of this project are: “The project of Tianhe River flood prevention and controlling”, “The project of Xijiagou flood prevention management and the environment improvement”, “the construction project of city drainage system and waterlogged draining pumping station”, “The project of flood prevention and waterlogged elimination and the environment improvement at Longzihu River”, “the project of flood prevention and waterlogged elimination and the urban environment infrastructure improvement in upper Huaihe zone”, “the project of flood prevention and the ecological environment treatment in Guzhen County”, “the project of flood prevention and the ecology environment treatment in Huaiyuan County” and “the project of flood prevention and the ecology environment treatment in Wuhe County”. 3.1.3 Project progressing plan Using the loans from the World Bank, Bengbu City plan to complete in 2012 the project of flood prevention, waterlogged elimination and the urban environment infrastructure improvement. The construction period is from 2008 to 2012, and 2006~2008 are in the project early preparing stage.

4. Environmental impacts and mitigation measures
4.1 Environmental impacts 4.1.1 Environmental impacts in construction period The construction period of this project is quite long and there are many residential area along the road, so the project construction may bring quite a lot influences on the environmental sensitive points. 1. Waste water The wastewater in the construction process includes production work wastewater and constructor’s sanitary sewage. The main origin of production wastewater includes: water seepage excavated from the hole in building foundation channel dredging project; the construction work wastewater during the concrete curing process, the main pollutant is the suspension; Under the natural rainfall and the surface washing effect, the pollution in the scouring sludge ,which is stored beside the bank, infiltrates or filtrates from the side with the stream runoff, resulting in second pollution to underground or the surface water body. Because of the construction machinery cleaning at the working site and the fuel oils leaking or dripping, a little construction wastewater containing the greasy dirt is produced. In the process of scouring sludge/silt storage, wastewater leaks from the draining silt with the suspension as the main pollutant. There is no toxic and hazardous substance in the production waste water. When discharging into the water environment, the major effect is suspension increase in the water. The sanitary sewage comes from the constructor daily lavation and cafeteria draining water. 2. Air In the construction process, the main atmospheric source of pollution produced is non-organized discharges of the raising dust, the waste gas of fuel oil and the odor from the dumping sludge place. The principal constituent of raising dust is TSP. The construction raising the dust mainly comes from the folk recipe excavating, floating and leakage in the material transportation process as well as in the processes of material loading, unloading and storing. The raising dust on the road comes from the construction machinery and the vehicles moving process. Raising dust emissions’ way is the intermittent indefinite quantity discharging. The influencing scope is the nearby the working site and along the transportation road.
The essential components of the waste gas of fuel oil are SO2, CO and NO2. They mainly come from the carrier vehicles and construction machinery using the fuel oil as the power. The influencing scope is the working site and along the transportation road. The odor from the dumping sludge place mainly includes the polluted sludge containing the spoiled organic matter breeds. When piles on the surface, may cause non-organized discharge of the odor material. It main materials causing the odor are the ammonia, the hydrogen sulfide, the volatile hydrogen, the volatility alcohols and aldehydes. 3. Noise The water pump, the excavator, the bulldozer and so on. will be used when river course dredging. In bridge construction, the drop hammer, the hoist, the bulldozer, the bulldozer and so on will be used. In the road engineering constructions, the road roller, the bulldozer and the concrete pushing machine and so on will be used. When in operation, noise of 1m annoyance to these mechanical devices curve acoustic source in 75~105db(A). The highest Annoyance value is from the drop hammer, its 1m annoyance value is approximately 95~105db(A). 4. Solid waste In construction period, solid waste produced includes construction residuals at working site, waste soil as well as constructor's life trash. 5. Ecological environment In the project construction process, before the scouring project water will be discharged completely from the construction section. The excavating and scouring of big ditches may cause influence to some benthoses. But it is temporary to the influence of the excavating and scouring of the river course on the aquatic biological speeches. When the scouring project ends, the water quality enhances, the aquatic biological survival environment will obtain restores with the improvement. In the construction process, it is a principle to take as far as possible little land, which reduces the destruction of the vegetations on both sides, and reduces soil erosion which the construction may bring.

Water Treatment Plant The main sources of pollution in operation period are solid wastes (including sludge, life trash, etc.), pumping house noise, sanitary sewage in the factory district and so on. The main pollutants in the sanitary sewage of the water treatment plant are: SS,
BOD5, the ammonia nitrogen, COD and the animal and vegetable oils. The wastewater in the sludge removing in the sedimentation pond and the wastewater of the counter-flushing in the counter-flushing filtration pond disperses completely into the newly built sludge concentration basin in the factory district (moisture content 99%). Then concentrated sludge after the precipitation (moisture content 97%) is sent to the dehydration process and the filter cake is formed after filtration press dehydration (moisture content 80%). Then it is ready for shipment processing. While the filtered water from the sludge dehydration process returns to the water well and mixed with the raw water. There is no waste gas in normal operation process in the water treatment plant. But there is some with the leakage of the chlorine cylinder in the unusual situation. The noise of mechanical devices operation in the water works is produced in the blower room and the pumping room, respectively. The power of noise source of air blower and the water pump is 80~90db(A). The solid waste mainly includes the staff living trash, production sludge in the water works and the packing materials of the reagents added. 2. The wastewater treatment plant The main source of pollution in operation period are the solid wastes (including residual sludge, grid dregs, sinks granulated substance, etc.), the noise, the sanitary sewage and the production waste water in the factory, the odor and so on. The waste water includes discharging water emissions in sewage factory and the sanitary sewage in the factory. The sanitary sewage in the factory disperses into the sewage factory feed pump station directly. The odor discharging facility in the sewage treatment plant is mainly the grill and the feed pump room, the sand collector, the biological reaction pond, the sludge concentration basin and the sludge dehydration room and so on. The emissions way is non-organized discharging. The typical odor pollutant is H2S and NH3. The noise source in the sewage factory is the mechanical power noise such as the pumping equipments, the air blower, etc. Among the solid wastes, it is quite few of the thick grill dregs, the thin grill dregs and the sunk granulated substances and so on. While the main solid waste is the sludge cake which is the residual sludge removed from the second sinking pond and then is produced with the concentrated dehydration. 3. Road In the development zone, the main pollution produce in the operation period are the exhaust gas mainly from the automobile discharging; the noise produced when the vehicles move; the pollution from rain water runoff on the road. When the road completes the air pollutant will be mainly the exhaust gas which automobiles produce with its principal constituent of hydrocarbon, nox, CO. The exhaust pollutants will affect the whole atmospheric environment along the route because of the diffusion in the air. Except for the traffic volume, the affected scope is related to the diffusion conditions such as the local wind speed, wind direction, barometric pressure and atmospheric stability. The traffic noise influence assumes the linear pollution characteristic and has the continuity and gradualness. Its influenced scope is related to the traffic volume, the noise present situation as well as the sound environment standard and request during the daytime or at night. The density and the emission amount of the pollutant in the road rain water are concerned with many factors such as the traffic motor volume, vehicle type, precipitation intensity, rainfall cycle, path type and vehicle fuel performance, etc. It is usually difficult to estimate. Known from analogy, the pollutant density in the road rain water will have a changing process from large to small. The pollutant density will reach the highest in 0~15 minutes, reduce gradually afterwards, and tend to be steady after an hour of raining.
4. Drainage Station In this project, solid wastes are divides into two parts: the production waste and the staff living trash. In the operation of Drainage Station, there will be some waste residuals as there are the dirt grills and the dirt-clearing equipment at the station entrance. They are mainly the leaves, the branches, the water plants, the textile fibers, plastics and rubbers and other solid floating matter in the effluent.

4.2 Mitigation measures
According to the environmental impact assessment documents and the project
characteristics, based on the analysis of the project’s pollution emission stages in the
construction period and in the operation period, the environmental impact mitigation measures
are proposed in view of the different type of pollutants, at the different time intervals and the
different places, respectively. See Table 4-2-1 for details.
Table 4-2-1 Abstract of the environmental impacts and the mitigation
measures Stage Environmental Mitigation Implementing Type Note factor measures agency Carries on the enough Before investigations and discussions to Based on the overall plan construction Land the project construction scale, Design Ecological and the flood prevention occupying reduce the amount of land organization plan occupying and relocations as few as possible Build temporary draining ditch around the construction site and the sedimentation pond in its low place. The construction wastewater and the site pond are discharged after meeting the standards after precipitation. The sludge wastewater on the construction site needs to be moved to the In special site using specific tunnels to be
dried which has, it is forbidden to discharge it to the agricultural field or the Construction water nearby. Sewage at the The constructors use the existed living construction facility near the construction site as far Water site , Construction Period as possible. For those temporary environment construction quarters sanitary sewages are sent to the organization working municipal sewage treatment plant for wastewater effective processing after septic tank processing, using special dirt collection vehicles. For those quarters in the city the sanitary sewage is connected to the municipal administration sewage pipe network for processing by the sewage treatment plant after septic tank processing. Enhance the management of raw material and construction site, reduces the temporary occupying of land.
