Law of the People's Republic of China on Prevention and Control of Environmental Pollution by Solid Wastes (1996.4)? Environmental Impact Assessment Law of the People's Republic of China (2003.9) Background? China has been carrying out environmental impact assessment of construction projects for more than 20 years, and it has become one of the most effective environmental protection systems in China.? What we currently call environmental impact assessment refers to the method and system of analyzing, predicting and evaluating the environmental impacts that may be caused by the implementation of a construction project, proposing countermeasures and measures to prevent or mitigate the adverse environmental impacts, and following up on them. Regulatoryization of the environmental impact assessment system? In order to implement the strategy of sustainable development, prevent adverse environmental impacts caused by planning and construction projects after implementation, and promote the coordinated development of economy, society and environment, China formally implemented the Environmental Impact Assessment Law in September 2003, expanding the existing environmental impact assessment of construction projects to environmental impact assessment of development planning, and China's environmental impact assessment system will be developed in the direction of global strategic environmental assessment. The EIA system in China will thus develop in the direction of global strategic EIA. Principles of environmental assessment? Environmental impact assessment must be objective, open and fair, and comprehensively consider the possible impacts on various environmental factors and the ecosystems they constitute after the implementation of a planning or construction project, so as to provide a scientific basis for decision-making. Environmental evaluation should generally be intervened in the feasibility study stage of the project, which is actually equivalent to the environmental feasibility assessment of the project. The State encourages relevant organizations, experts and the public to participate in environmental impact assessment in an appropriate way. Categorized management of environmental evaluation? The State implements categorized management of environmental impact assessment of construction projects according to the degree of impact of the construction project on the environment.? Construction units of different scales shall, in accordance with the regulations, organize the preparation of environmental impact reports, environmental impact report forms or fill in environmental impact registration forms, which are collectively referred to as environmental impact assessment documents. Environmental assessment organizations? Institutions providing technical services for environmental impact assessment of construction projects shall be qualified by the administrative department of environmental protection under the State Council, issue qualification certificates, and engage in environmental impact assessment services in accordance with the level and scope of assessment as stipulated in the qualification certificates and be responsible for the assessment conclusions. Our organization has the evaluation organization with the Class A qualification certificate issued by the state. Methods and contents of environmental assessment? There are many contents involved in the method of environmental assessment, but the general principle is based on the Technical Guidelines for Environmental Impact Assessment. The contents and format of the environmental impact report, report form and registration form shall be formulated by the administrative department of environmental protection under the State Council.? The environmental impact report shall include the following contents: evaluation factors? Atmospheric evaluation factors. Status quo evaluation: SO2, NO2, TSP, PM10 and CO; predictive evaluation: SO2, NO2, soot (dust), toluene, xylene. Water environment evaluation factors. Status evaluation: suspended solids, permanganate index, BOD5, dissolved oxygen and ammonia nitrogen; predictive evaluation: COD, BOD5, ammonia nitrogen.? Noise evaluation factors: LaeqdB and maximum sound level.? Ecological evaluation factors: greening area, ecological suitability, ecological satisfaction. -----------------------Page11----------------------- main pollution sources during operation period?

Noise (3) Paint spraying room and drying room (1) Transportation (4) Vehicle debugging and commissioning (2) Equipment (5) Mobile source vehicles? Solid Waste Regional Environmental Quality Condition? Atmosphere: Ambient air quality is good.? Water bodies: In 1999 and 2000, the lower part of Chaobai River was Class V and Super Class V water bodies respectively; after 2001, Chaobai River and Yueya River broke the flow. The groundwater quality in the project area is good.? Ecology: The project area is now mainly an agricultural landscape area in the transition zone between urban and rural areas, and the agro-ecological system is dominant.? Acoustic environment: The acoustic environment in the north side of the project area is poor. The sound environment in other areas is good. Pollution status of the evaluation area? Atmosphere:Residents of Henan Village, Linhe Village and Wangjiachang Village emit air pollutants by burning coal.? Water:Residents and industrial enterprises discharge 4.358 million t/a of wastewater. Solid Waste:Residents and enterprises produce domestic garbage and coal-fired slag, with a total emission of 53,300,000t/a.? Noise:Mainly from residents' living noise and road traffic noise. Atmospheric environmental impact prediction and evaluation? The SO and soot emitted from natural gas-fired boilers and incinerators have a small impact on the surrounding environment, but NO has a certain impact, thus certain measures should be taken. The predicted concentrations of dust, toluene and xylene in the waste gas of the production process are all within the standard values and have little impact on the surrounding environment. After the completion of the project, a certain amount of tail gas pollutants will be emitted from in and out of motor vehicles. At present, Beijing is gradually increasing the control of motor vehicle pollution, requiring all motor vehicle exhaust on the road to meet the European 2# standard, so the impact of motor vehicles on the surrounding environment should not be significant. Noise impact prediction? After each enterprise moves in, the noise of its factory boundary can reach the "Noise Standard for Factory Boundary of Industrial Enterprises". Therefore, the borders of the industrial community can also meet the above standards, and the impact of equipment noise on the sensitive targets outside the zone is very small. After the completion of the industrial park, the roads in and out of the industrial park are mainly used by all kinds of transportation trucks and commercial vehicles, and the impacts of single-vehicle noise on the public areas of the enterprises, the living areas of the workers and the nearest village of Henan Province (30m away from the industrial park) are small. Out-of-boundary traffic noise has a greater impact on the commercial services and public facilities of the industrial community arranged on the side of the adjacent road, and protective measures must be taken to reduce road noise. Water environment impact analysis? Wastewater mainly includes industrial wastewater and domestic sewage, which is discharged into the municipal sewage network after treatment by the sewage treatment station of each enterprise, and finally enters into Shunyi District Sewage Treatment Plant. The indicators of each of these pollutants are in line with the water pollutant discharge standards for entering the municipal wastewater treatment plant.? The water is used to irrigate green areas for a long time, and the increase of pollutant concentration in the downstream direction of groundwater is very small, which will not affect the drinking function of groundwater. Ecological environment impact analysis? After the completion of the project area, it will become a complete urban ecosystem. Although there is no essential difference between the vegetation type and the current situation, the ecosystem function will be improved due to the diversification of green tree species and multi-level. Ecological suitability analysis: the project area is suitable to be developed into industrial land, but the industrial layout is restricted by high voltage lines.? Eco-satisfaction analysis: The ecological satisfaction value of Renhe Industrial District after completion is 54.8, which is at a medium level, indicating that the overall function and layout of the project area can meet the needs of people's production and life. Total Pollutant Control Quantitative calculation of total air control? Adopt the target concentration control method: Consider the amount of pollution contributed by enterprises, institutions and residents outside the region to the air environment in the industrial district, and superimpose the concentration values of various pollutants emitted by them to the industrial district contribution. The concentration margin of the pollutants in the community, i.e. the difference between the above superimposed values and the environmental secondary standards, is used as the total control target. Total amount control target values: 11.514t/a, 2.062t/a, 0.375t/a, 0.625t/a and 48.55t/a for SO, soot, dust, toluene2 and xylene, respectively. total water pollutant control o Total amount of discharge control based on the constraints of technical and economic conditionsThis method is based on the technical and economic conditions of the cell wastewater to enter the wastewater treatment plant, to determine the dischargable wastewater quality, and determine the amount of wastewater through analogous surveys, so as to calculate the total amount of control targets for the district. o Total emission control based on environmental capacity constraints Determine the emissions based on the current situation in the project area, such as fertilizer leaching, loss of organic nitrogen from the soil, wastewater from the residential area and drainage from the fish ponds, etc., and use the current situation of emissions not to increase as a target for the total amount of control. Total water pollutant control value pollutant CODNH-N4 total emission 84.7717.75(t/a) Air environmental protection measures? Exhaust gas of welding workshop and assembly workshop is discharged by exhaust pipe. Paint spraying (refinishing) room is installed with water spinning paint mist treatment device, the treatment efficiency should be more than 95%, and the height of the exhaust pipe should not be lower than 20 m. Organic waste gas generated in the drying room should be treated by incineration method to ensure that the removal rate of toluene and xylene is more than 98%. The height of incinerator chimney should not be lower than 15m. Strengthen the management of vehicles to reduce the emissions of exhaust pollutants from vehicles. Water environmental protection measures? This report suggests that the park should build a unified wastewater treatment plant. o Each production enterprise should first pre-treat their own wastewater before sending it to the wastewater treatment plant. o The wastewater treatment plant should have a capacity of at least 1,000 tons. The treatment capacity of the wastewater treatment plant should be at least 4,800t/d. The wastewater treatment process can be one of contact oxidation method and complete mixed activated sludge method. o The wastewater treatment plant should be equipped with a water treatment plant. Set up a water reuse system in the industrial area, and reuse the treated water for greening and dust reduction in the park. Construction of storage tanks to store the standardized wastewater that cannot be reused, and at the same time can be used as an ecological landscape to improve the environmental quality of the area, but also to collect precipitation. Excess standardized wastewater can be discharged to the south into the Yueya River. Sound environmental protection measures? The boiler room is built in a location with few surrounding sensible people, and the boiler and other related equipment and facilities in the boiler room are installed with attention to adopting noise control measures such as acoustic absorption, acoustic isolation, muffling and vibration isolation, etc.? For the noise of industrial enterprises, attention should be paid to the adoption of local noise control measures and vibration isolation measures.? Construct a 30m wide green belt that adopts a combination of trees, shrubs and grasses with trees and shrubs on the south side of Shuanghe Road on the north side of the industrial district. Install sound-insulating windows on the street side of the public **** facility rooms. Solid waste control measures? Domestic garbage can be transported to Shunyi District Garbage Treatment Plant for unified treatment by the sanitation department all by closed trucks on a regular basis.? Industrial solid waste is collected in categories, stockpiled at fixed locations, and the stockpiling site adopts seepage-proof and rain-proof measures, as well as measures to prevent scattering and flying in order to avoid the problem of secondary pollution. Industrial solid wastes and dry sludge containing heavy metals and other hazardous wastes are stored separately and sent to the hazardous waste treatment center. Environmental and economic analysis?
