江苏省环境科学研究院 5 Jiangsu Provincial Academy of Environmental Science 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant 1. General Origin of tasks All countries in the world are now faced with one of major environmental problems, namely the municipal solid wastes. In China it becomes more and more obvious. With the development of economy and the improvement of living standards as well as the acceleration of the urbanization, a number of domestic wastes get more and more, so that in general, the pollution resulting from municipal solid waste is becoming more and more serious. Currently, the common methods for innocuous disposal include sanitary landfill, incineration and comprehensive utilization. The advantage of incineration disposal is so effective to reduce wastes. After the incineration, the volume of waste is reduced by 90% and the weight by 80%. Also, the heat energy from the incineration can be effectively utilized for heating and generating the power, enabling the waste to become a new resource. Meanwhile, the incineration of waste realizes effective reduction of domestic waste, hazard-free treatment and resources recycling, which endows the incineration with higher social value and economic value. Sanitary landfill is currently used to dispose domestic waste in Zhenjiang city. In May 2003, the Phase-I for Solid Waste Landfill in the east of Zhenjiang city was completed, where the restoration of ecological environment was made. Meanwhile, the Phase-II for its Solid Waste Landfill was initiated subsequently. The designed aggregate storage of the Phase-II Project is about 1,800,000 cubic meters, which promises to be used until 2010; with the urban development and the reconstruction of Binjiang New District, the expansion around the original solid waste landfill is impossible; therefore, another location is required for the expansion of solid waste landfill. After comprehensive discussion and comparison from the perspectives of the development, economic capability, nature of solid waste, technological level etc. of Zhenjiang city, it is considered that Zhenjiang city has the capacity of utilizing incineration technology. Therefore, it is favorable to adopt the method of power generation via incineration of solid waste as disposal of solid waste. That is, giving priority to power generation via incineration with sanitary landfill (slag) as the complement, where a comprehensive disposal method integrating with multiple disposing manners is used. This is able to prevent the solid waste from polluting environment, and to utilize the heat energy from incineration for power generation, which realizes environment protection and economic benefits. In order to substantially improve the environmental quality and accelerate the building of ecological city, Zhenjiang municipal government has decided to franchise the project for power generation via incineration of solid waste, where the landfill of solid waste is basically replaced by the incineration. In July 2009 Zhenjiang municipal government determined China Everbright International Limited as its partner through the public tender. The BOT (Build-Operate-Transfer) mode is adopted for the project of power generation via incineration of solid waste in Zhenjiang city, with a franchised period of 30 years. Everbright Environmental Energy (Zhenjiang) Co., Limited that China Everbright International Limited invested in will become the construction unit of the project. According to relevant environmental laws and regulations such as Law of Environmental Protection and Law of Environmental Impact Assessment of The Peoples Republic of China, the environmental impact assessment shall be conducted during the feasibility studies of the project. Therefore, the construction unit will entrust Jiangsu Provincial Academy Of Environmental Science to conduct environmental impact assessment for this project. On receipt of such a commission, Jiangsu Provincial Academy of Environmental Science promptly made on-site survey and investigation. After accumulation and verification of

江苏省环境科学研究院 6 Jiangsu Provincial Academy of Environmental Science 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant relevant data available, the project team should prepare the environmental impact report of the project according to national environmental protection laws and regulations as well as relevant standards and specifications. (The environmental impact assessment only include refuse incineration power plant, but the auxiliary landfill project as stipulated in the document of Touzifa No: 2009-126 issued by Jiangsu Development and Reform Commission is not included in this environmental impact assessment. The project will utilize the existing solid waste transfer station, and no additional one is required to be established.)

1.2 Objectives of assessment The cleanliness degree of production process is determined through the analysis on the project and cleaner production; the feasibility of anti-pollution measures is verified through the perspective of technology and economy, where the impact of the project on environment is predicted by estimating the impact of pollutant resulting from the project on surrounding environment; verify the index of total emission of major pollutant resulting from the project, analyze the channels for achievement of such index, and analyze the feasibility of the project from the perspective of controlling total pollutant emission; the feasibility of local project can be determined through integrated analysis on environmental protection, so as to provide scientific basis for approval of environmental management and for engineering design of this project.

1.3 Principles for assessment The principles for the environmental impact assessment are as follows: (1) According to relevant regulations on environmental protection management of construction projects stipulated by Jiangsu provincial authorities, the cleaner production, standard emission and the control of total emission are used as the overall principles for this assessment to strengthen the analysis of the project and its total emission control. (2) The environmental impact assessment of this project is conducted according to the overall planning of Zhenjiang city and its industry planning, with effective utilization of recent achievement on environment monitoring and management obtained from where relevant projects are conducted. (3) The assessment results are objective and true, providing scientific basis for environment management of this project.

According to classification methods of assessment stipulated in Atmospheric Environment for Technical Guidelines for Environmental Impact Assessment（HJ2.2-2008)) , the assessment level of this project is determined as level II. Determination for the level of surface water impact assessment After pre-treatment in waste-water washing plant and subsequent connection to pipes, the leachate resulting from this project will be transmitted, together with domestic sewage, to Dagang sewage treatment plant for treatment via city sewage discharge network; after final treatment when the waste water reaches level A, the water will be discharged to Dagang River. In this environmental impact assessment, a simple analysis is made on environmental impact assessment of surface water. Determination for the level of noise impact assessment The noise environment assessment area of this project takes Class III and Class 4a stipulated in Environmental Quality Standard for Noise（GB3096—2008 as reference. Considering the fact that there is no sensitive object within 300m around the project, the level of environmental impact assessment on noise is determined as Level III. Determination for the level of ecological impact assessment As the scope for assessment is less than level of environmental impact assessment, it does not belong to sensitive area and there is no rare or endangered species within the scope. Therefore, according to Technica1 Guidelines for Environmental Impact Assessment Eco1ogical Environment of Nature Resource' Development, the level of ecology impact assessment is determined as Level III. Determination for the level of environmental risk assessment

Overview of process flow The waste is transported by special vehicles to the inlet of waste receiving system in the plant. After weighing, it will be unloaded into the Waste pit for fermentation. In order to stabilize the combustion process, repeated rolling and mixing by crane is required, so as to homogenize the waste. The homogenized waste will be sent to incinerator according to load. The burning gas of incinerator is extracted by blower from upper part of Waste pit, and supplied to furnace as primary air, while the secondary air is supplied from incinerator room. When the incinerator is operating under normal condition, the waste will locate on the grate, where incineration is completed, and the subsequent slag will fall into the slagging machine, from which the slag is extracted out by hydraulic devices for further treatment. The heat energy produced will be absorbed when it pass through surface of boiler, and will then be sent to generator sets for power generation after it passing super heater which can generate medium temperature and medium pressure superheated steam（400 、 4.0MPa) . The fume resulting from incineration will be treated by fume purification system, ensuring the pollutants content in fume are below the national allowable℃ standard value. The fume will then be emitted to the ambient air through chimney of 80m height.

2.6 Generation and discharge of pollutants, and corresponding prevention and control measures

2.6.1 Main pollutants-derived and emission 2.6.1.1 Wastewater The wastewater from the proposed project mainly includes leachate, domestic sewage, and water for cleaning refuse unloading platform (1) Drainage of clean sewage Closed circulation water supply is used for cooling system of generator. In order to control concentration of calcium and magnesium in water, it is required to periodically discharge part of circulating water, to regularly clean the condenser. The waste water resulting from such cleaning is about 504m3/d, where there are few calcium and magnesium. All waste water is used for preparation of demineralized water, and for washing of refuse unloading platform and vehicles without discharge outside. The regular discharge of boiler is used as recharge water for cooling tower without discharge outside. The condensed water （192m3/d) from reverse osmosis system resulting from preparation of demineralized water is used for solidification of Fly ash, cooling of slag, only a few of the water （48m3/d) is discharged as clean sewage Amount of wastewater and water quality Wastewater from waste pit system The yield and components of leachate are affected by many factors, which bring about significant uncertainty. Furthermore, the leachate is one of the organic wastewater that is hard to treat. Taken the waste quantity of the project at 1000t/d, and the average annual yield of leachate at 25%, the treatment capacity of this project is calculated at 250m3/d. The leachate is high-concentration organic wastewater. The wastewater will be sent to leachate treatment station for treatment. When the water meets requirement of pipe connection, it will be transmitted into Dagang Sewage Treatment Plant for further treatment. Wastewater resulting from cleaning refuse unloading platform, and water for cleaning vehicles and waste shaft The refuse unloading area also needs to be cleaned so as to keep clean environment. The daily wastewater resulting from cleaning refuse unloading platform, waste shaft and waste trucks is about 24m3/d. The wastewater together with leachate will be sent to leachate treatment station for treatment. When the water meets requirement of pipe connection, it will be transmitted into Dagang Sewage Treatment Plant for further treatment. Domestic sewage The discharge of domestic sewage is about 14.4m3/d. According to different kinds of wastewater, each kind of wastewater quantity and water quality are shown in table 2.6-1

The yield of pollutant is calculated according to average concentration.

2.6.1.2 Waste gas The waste gas of the project mainly comes from incineration system, waste pit system and the leachate treatment devices. The fume of incinerator enters into fume purification system via the boiler. The fume purification system consists of acid gas removal tower, active carbon spray device, bag-type dust-collector, induced draft fan and fume pipe. The system, together with corresponding incinerator and boiler forms three lines. The three sets of fume purification are arranged in parallel. After purification the waste gas is discharged into the air through the chimney with height of 80m. The generation and discharge of atmospheric pollutants are shown in table 2.6-2. (1) The source of fume components is analyzed as follows: Acid components HClMunicipal solid waste contains plastics and various kinds of organic chloride (according to measured results① of components, the plastic content of treated in this project is about 60590t/a) . The HC1 is mainly generated from heat decomposition of chloride. During combustion of PVC and waste (disinfected with chloride or bleached), the HC1 will be generated, While the chloride existing in kitchen waste in the form of inorganic form will not generate HC1. Compared with similar projects, the yield of HC1 in this project is 109.8kg/h and 878.4t/a respectively. After fume purification, the discharge of HC1 is 10.98kg/h and 87.84t/a respectively. HF: Fluoride is produced from incineration of chlorofluorocarbon in waste, such as fluorine plastic, fluorocoating. The generation manner of HF is similar to that of HC1, but with relatively low quantity. SO2The generation of SO2 comes from incineration of domestic waste and ignition of incinerator. The sulfur content in waste of Zhenjiang is about 0.17％. Compared with similar data, the transformation ratio of sulfur in waste is 80%, and the yield of SO2 during incineration is 992.8t/a. take into account the sulfur content（≤0.3％) in light diesel (annual consumption of 150t/a) consumed during ignition, and assume the production of SO2 during combustion of light diesel, it can be obtained that the annual yield of SO2 is 993.7t/a. The desulphurization rate of waste gas treatment devices in this project is taken at 78% and the discharge of SO2 at 218.61t/a. NOXIt mainly comes from heat decomposition of nitrogen compound and combustion, and a few is from burning （below 1100 ) of nitrogen in the air. The estimated yield of nitrogen oxides is 58.56kg/h and 468.48t/a COPart of CO comes from heat decomposition of carbide in waste, and the remaining come from incomplete combustion. Higher efficiency℃ of waste combustion will result in less yield of CO. For this project, the emission concentration of CO can be controlled at 100mg/m3, and the discharge of CO is 18.3kg/h,146.4t/a Dust During incineration of waste, most dust is discharged in the form of bottom ash. The dust in fume normally accounts for about 3%~4% of total quantity of waste. Assume the incineration amount of waste is 365000 t/a, then the yield of dust for this project is 10980t/a (1372.5kg/h). After purification by semi-dry neutralization and bag-type deduster, the dust with large grain will be removed, and the dust discharged outside is mainly PM10. The treatment method of “semi-dry deacidification + active carbon absorption + bag-type deduster” is used for incineration of fume in this project. Each incinerator is provided with one set of deacidification and dust-removing device, with unit system. The three sets of equipments are of independent system respectively. Each set of fume treatment device consists of storage and transmission device of absorbent, feed device of active carbon, deacidification reactor, bag-type deduster, water circulation and fluidization device for ash, fluidized draft fan, water addition device and pneumatic transport for ash. After treatment, the fume from incineration will discharged through chimney (internal diameter of outlet is 3×1.6m) with height of 80m. Heavy metal According to analogy investigation, the emission concentration of Hg, Cd and Pb in incinerator is taken at 1.0mg/m③ 3, 5.0mg/m3 and 10.0mg/m3respectively. After purification of fume, the removal rate of heavy metal can reach 80％, 99％ or more than 90％ respectively. Therefore the yield and discharge of heavy metal in waste gas can be obtained as shown in table 2.6-2. Dioxins Dioxin-like chemicals is a general term for the compounds which are able to combine with Ah-R and cause a series biochemical effects. It mainly includes 75 kinds of PCDDs and various kinds of PCDFs, where PCDDs and PCDFs are collectively referred to as dioxin. In addition, it also includes PCBs and hydroxy-diphenyl ethers. In the

known dioxin-like chemicals, the ones with obvious virulence are 7 kinds of PCDDs, 10 kinds of PCDFs and 12 kinds of PCBs, of which 2378-TCDD are most toxic. Dioxins are hard to be dissolved in water, but are easily dissolved in fat and then accumulate in organism. Thus it is hard to be discharged, and it is hard to be decomposed; the dioxins have low steam pressure, which makes it unable to evaporate from surface under normal ambient temperature; it is relatively stable under the temperature of 700 , and decomposition will start from this temperature. The three features determine where the dioxins will be discharged. When the dioxins enter into organism and accumulate through food chain, they will cause transmissible and℃ accumulative poisoning. . During incineration of domestic waste, the generation mechanism of dioxins is quite complicated. Up to now, the research results at home and abroad are insufficient to explain the problems. The generation manners of dioxins known to us may include the followings: A. The domestic waste contains a few dioxins. As the dioxins have thermal stability, although most of them are able to be decomposed, a few of them are discharged after burning; B. During burning, chlorine precursor will produce dioxins. The precursors include PVC, chlorobenzene and PCP etc. during burning, the dioxins will be produced when rearrangement of precursor molecules, condensation of free radicals, dechlorination and reaction among other molecules occur. Most of the produced dioxins will be decomposed under high-temperature burning. C. When there are excessive unburned matters in fume resulting from incomplete combustion, and when there are appropriate media (mainly heavy metal, especially Cu etc) and under the ambient temperature of 300~500 , the decomposed dioxins under high-temperature burning will be re-established. The factors affecting production of dioxins are quite complicated. The concentration of dioxins resulting℃ from incineration of domestic waste is 5~10ngTEQ/Nm3. As the processing equipments used in the project are internationally advanced, the concentration of dioxins produced is about 5ngTEQ/Nm3 and the yield approximates 0.915×106ngTEQ/h. The average emission concentration of dioxins in Taicang Xiexin project is 0.074ngTEQ/Nm3. The average emission concentration of dioxins in Shanghai Jiangqiao Domestic Waste Incineration Plant (invested by Shanghai Environment Group Limited) is 0.068ngTEQ/Nm3. If a series of prevention and control measures (such as absorption by active carbon) are adopted in this project, the concentration of dioxins in the fume will comply with the EU standards (the current standard is 0.1 TEQng/m3), then the emission of dioxins is 1.83×104ngTEQ/h.

(2) Odor

According to analysis, the odor pollutants (such as NH3, H2S etc) during operation of the project mainly come from waste pit and leachate treatment station. The whole waste pit is of enclosed configuration completed with negative pressure system, so as to prevent leakage of odorous gas. Meanwhile, the gas in the pond on upper part of waste pit is extracted and then, after pre-heating, sent to incinerator as primary air for combustion purpose, thus controlling emission of odor. Sealing is considered to be provided for major buildings producing odor during treatment of leachate, so as to emit the odorous gas to negative pressure area of the waste pit. The odor is not emitted outside. For the sake of safety, the odorous gas produced in the waste pit under abnormal conditions of this project is calculated with reference to the measuring method for calculating yield of odor pollutants in Waste Landfill. Compared with municipal Sewage Treatment Plant, the odorous gas of sewage treatment station is dominated by NH3 and H2S etc. The production coefficient of odorous gas in the waste pit is shown in table 2.6-4. Table 2.6-3 Coefficient of odorous gas in this project odorous gas NH H S source 3 2 15 60.59 6.20 Waste pit （g/t waste·a) 30 86.68 8.87 Leachate treatment station（mg/s·m℃2) 0.842 0.0026 The daily storage capacity of refuse℃ unloading lobby and waste pit is calculated according to the treatment capacity of 7 days. The maximum storage capacity of the waste is 7000t. The area of regulating pond of leachate treatment station is 220m2. Thus, the yield of odorous gas is calculated as shown in table 2.6-4 Table 2.6-4 Yield of odorous gas in this project Odorous gas NH H S Source 3 2 Waste pit 0.069kg/h 0.007 kg/h Leachate treatment station 0.667kg/h 0.00206 kg/h

The leakage amount is calculated by assuming the yield of waste pit at 10% and leachate treatment station at 20%.

(3) Dust

During solidification of fly ash, a little dust will be generated. The design treatment capacity of fly ash solidification system is 6t/h, taken 8 hours per day and annual working days of 330d for calculation. Through analogy analysis, the yield of dust of the project is 1.93t/a, with area of 360m2 and height of 8m.

2.6.1.3 Noise-derived and its emission

The solid waste produced in the project mainly include metal waste, slag, fly ash, waste ion-exchange resins, used oil and domestic waste, with the total amount of 115131t/a.

(1) Metal waste The metal waste of the project comes from domestic waste. The metal waste will be extracted by magnetic separator which is installed on vibration conveyor belt in deslagging system.

(2) Slag According to the design data of this project, the yield of slag is 94870t/a, accounting for about 26.0% of waste treatment capacity. It is intended to comprehensively use the slag.

(3) Fly ash The method of "reaction tower + bag-type deduster" is used to treat fume from incinerator. The reactants accumulated by bag-type deduster, incompletely reacted ammonium polyacrylate and waste active carbon will form fly ash. The yield of fly ash in the project is about 14600t/a (accounting for about 4.0% of waste treatment capacity). For this project, chelating agent is added to stabilize concrete. After stabilization of fly ash, the total wet ash produced is 19417t/a. According to National Hazardous Waste Inventory, fly ash is hazardous waste. The slag numbered as HW18 (802-002-18) will, after stabilization in plant, be transported to auxiliary landfill for burying. (In case the auxiliary landfill is not completed according to schedule, the fly ash is sent to Danyang Refuse Landfill until they are completed.)

(4) Other industrial waste There will be a little waste ion-exchange resins and used oil produced in the project, with the estimated amount of 1.3t/a and 2.7t/a respectively.

(5) Domestic waste It is expected that the domestic waste produced in this project is 23t/a which will be incinerated in plant. In addition, the leachate and sludge is about 50t/a. After dehydration, they will be incinerated together with domestic waste.

2.6.2 Proposed antipollution incentives

2.6.2.1 Prevention measures for wastewater The leachate and wastewater resulting from washing will be transmitted to leachate treatment station built in the plant for treatment; when the water meets requirement of pipe connection, it will be transmitted, together with domestic sewage, into Dagang Sewage Treatment Plant for further treatment via municipal sewage pipe network.

2.6.2.2 Prevention measures for waste gas (1) Waste gas from incinerator The treatment method of “semi-dry reaction tower + active carbon absorption + bag-type deduster” is used in fume treatment system of the project, to treat waste gas from incineration system. Each incinerator is provided with one lime slurry preparation system, which is able to supply high-quality active lime slurry to sprayer, so as to obtain maximum benefits and reduce① consumption of lime. Reaction tower and rotary sprayer; Acid gas in neutralized fume, part of absorbed/attached heavy metal and dioxins Absorption of active carbon; Absorbing residual heavy metal and dioxins Bag-type deduster; Acting as reactor to provide neutralization and absorption ③

functions while separating dust (fly ash) in fume and reactants. Induced draft fan. Extracting purified fume to chimney and keeping furnace at negative pressure state. The method of “semi-dry reaction tower + active carbon absorption + bag-type deduster” is intended to be used for fume purification of the project. After emitted from tail of boiler, the fume will enter into fume purification devices. After treatment when the waste gas meets requirements, it will be emitted to the air through chimney with height of 80m. (2) Odor The odor pollution comes from the odorous gas emitted from original waste into the plant, during transportation and unloading by waste trucks, as well as from waste in waste pit and leachate treatment devices. The odorous gas mainly includes H2S and NH3 etc. (1) Enclosed-type waste trucks are used. (2) Enclosed arrangement is used for refuse unloading lobby and waste pit, so as to design a relatively enclosed body. (3) Air curtain is provided at the outlet of unloading room in main house of incineration plant. (4) All gates in waste pit accessible to other area are provided with double-layer airtight doors. The rooms between the doors are used for isolation and damping purpose. Direction of each door is specially designed. (5) Automatic unloading airtight door is provided to closed-type waste pit. (6) Exhaust inlet of primary air feeder is led to waste pit. The air extracted from upper part of waste pit is used as oxidizing air, so as to form negative pressure in waste pit area, and to prevent leakage of odor. Likewise, exhaust inlet of primary air feeder is led to storage pond, forming micro-negative pressure in slag storage pond. The extracted air will firstly undergo filtering and dust-removing, and then will be sent to furnace after heating by pre-heater, whereby the odorous matters will be removed through decomposition and oxidization during burning. (7) Standardization management of waste pit. Using of grab to continuously roll the waste can not only make uniform the heat value of waste into the incinerator, but also prevent anaerobic fermentation and reduce production of odor. (8) Regular spraying of deterrent and deodorant in waste pit (9) During maintenance of incinerator, ammonia, hydrogen sulphide, methyl mercaptan and odorous gas produced from waste in waste pit will condense in the air and then leak outside. In order to prevent accumulation of combustible gas in waste pit, the electric calve and deodorization fan will be opened, whereby the odorous gas will be emitted into the air after filtering by absorption of active carbon when the gas meets relevant standards. Therefore, it is able to effectively ensure air quality in area where the incineration power plant is located in. (10) When the extracted air for injection is not sufficient where the required negative is not available in waste pit, and when there are special requirement for preventing and controlling odor pollution in incinerator, it is necessary to consider appropriate treatment for the extracted air by using active carbon absorption. (11) Leachate accumulation system consists of leachate pond, leachate pump house and channels. Mechanical air supply system and mechanical exhaust system are provided.

Meanwhile three deodorization fans are provided to supply air to waste pit. (12) Sealing is provided for structures treating the leachate, so as to emit the odorous gas to negative pressure area in waste pit.

2.6.2.3 Disposal measures for solid waste During the project period, a plenty of solid waste will be produced, including metal waste, slag, fly ash, waste ion-exchange resins, used oil, sludge for treating leachate and domestic waste etc. The metal waste of the project comes from domestic waste. The metal waste will be extracted by magnetic separator which is installed on vibration conveyor belt in deslagging system. The Solid wastes will be sold to steel plant for comprehensive utilization. According to similar leaching test data on slag of domestic waste, the slag is classified as ordinary Solid waste. The main components of slag are oxide of Si, Ca, Al, Fe, Mn, Na and P, as well as waste metal. The slag can be used as fuel for brick-making, aggregate for silicate products, insulation material for road construction or roof, and raw material for concrete. The slag of the project is sent to Zhenjiang Shengjie Used Oil Utilization Co., Ltd for comprehensive utilization. Fly ash refers to the fine grains accumulated in air pollution control equipments, normally including reactants accumulated by bag-type deduster, incompletely reacted ammonium polyacrylate and waste active carbon. Fly ash is hazardous waste. The fly ash, after stabilization in plant, will be transported to auxiliary landfill for burying. (in case the auxiliary landfill is not completed according to schedule, the fly ash is sent to Danyang Municipal Landfill until they are completed.) Domestic waste and sludge treating sewage may be sent to incineration system of the project for incineration treatment. A little waste ion-exchange resin and used oil (which are classified as hazardous waste) will be sent to Zhenjiang Shengjie Used Oil Utilization Co., Ltd for comprehensive utilization

2.6.2.4 Noise control measures The noise source of the project is mechanical noise produced from incinerator, waste-heat boiler, turbine generator units and various kind of auxiliary equipments (such as pump and fan etc). Reasonable arrangement, sound insulation and damping measures in plant house are adopted for the proposed project, so as to reduce impact on surrounding environment, and prevent noise disrupting residents. The noise control measures of this project is shown in table 2.6-8

2.6.3.1 Fault in fume treatment facilities Fume treatment facilities in the incinerator take into consideration the fume treatment effects under various normal operating conditions. Back-up measures are provided for such key parts as rotary atomizer in semi-dry reaction tower, active carbon spraying system and bag-type deduster etc. According to the actual operation of the project, it is extremely impossible that the fume treatment does not meet requirements resulting from fault in equipments. When the case occurs, prompt shutdown of incinerator shall be made (shutdown time lasting for about 1 hour). This case may occur less than 2 times in a year. The pollutants emitted during shutdown of incinerator are analyzed as follows: Under normal conditions, the bag may be replaced in batches on the basis of service period during maintenance of incinerator. The online monitor can promptly detect leakage in bag during operation. Many independent cabins are provided for bag-type deduster of this project. Prompt isolation and replacement will be made for leaked bags in certain cabin. Therefore, it is effective to treat dust grains. Under normal operating conditions, the dust-removal rate of bag-type deduster may be more than 99.8%. The dioxins attached to fly ash can be basically removed. According to monitoring statistics, in case of leakage in bag-type deduster, the maximum emission concentration will increase to the value of three times of that under normal condition. Therefore, the dust-removal rate will be 99.4%. According to relevant research results, when active carbon is added to bag-type deduster, the total concentration of dioxins in fly ash will increase from 254ng/g (without addition of active carbon) to 460ng/g. the reason is that the active carbon powder which absorbed dioxins will be collected by bag-type deduster into fly ash, resulting in increase of dioxins content in fly ash; therefore, the concentration of dioxins in the tail gas will be reduced. According to above analysis results, even the active carbon is not sprayed, the dioxins attached to fly ash is equivalent to 55% (254/460=0.55) of dioxins attached fly ash where active carbon is used. Therefore, when fault occurs in active carbon, it is also effective, to a certain degree, to treat dioxins attached to grains. The incineration system (semi-dry method + spraying of active carbon + bag-type deduster) used by Xinmin Thermal Power Co., Ltd is similar to that in this project. The purified tail gas is tested by Chinese Academy of Sciences---aquatic organism dioxins testing center. The test results are: dioxins in the ash is 0.00482TEQng／m3(fume amount is the value under standard state), and the dioxins in gaseous phase is 0.00023TEQng／m3. Therefore, when the active carbon is sprayed, the proportion of dioxins attached to fly ash is about 95%. Under the condition where the active carbon is not used, the dioxins will also attach to fly ash, and the amount is 55% (mentioned previously) of that when the active carbon is used. Then, when fault occurs in active carbon spraying, the amount of dioxins in bag-type deduster which is attached to fly ash is 52% (95%*55%=52%) of the total dioxins.

For this project, in case fault occurs simultaneously in bag-type deduster and active carbon spraying, the treatment efficiency of dioxins is 51.7% (52%*99.4％=51.7%) . For the sake of safety, multiplied by the coefficient of 87%, the treatment efficiency may be more than 45%. This assessment takes into consideration the least favorable condition. Namely, fault occurring simultaneously in active carbon of fume purification facilities and bag-type deduster, where the emission amount of dioxins reaches the maximum and the removal rate is 45%. To put is another way, the emission concentration is 2.75ngTEQ/m3 and the emission amount is 0.503mgTEQ/h. Assuming the hydrogen chloride is emitted under abnormal condition for 2-3 hours and removal rate is 50%, then the emission amount of hydrogen chloride is 54.9kg/h when fault occurs in semi-dry neutralization reaction tower.

2.6.3.2 Start-up and shutdown of incinerator During start-up (temperature increase) of incinerator, the temperature increase takes 2-4 hour from start-up of incinerator to normal operation of fume treatment system. In theory, when the retention time of fume under temperature of 850 reaches 2s, most organisms will be completely burned in incinerator, and there will be no dioxins produced. However, during start-up (temperature increase) and shutdown (closing), if the℃ temperature of incinerator is not sufficient, the dioxins will be produced. For this project, the ignition (shutdown of incinerator) will start auxiliary combustion system. If the countermeasures are not put in place, the concentration of dioxins produced during incineration will be obviously higher than that produced under normal operating condition. According to relevant data, UK has conducted tests for six companies on abnormal operating conditions when starting incinerators. The result is that the concentration of dioxins at outlet during start-up of incinerator is 2-3 times of that under normal condition. Assuming there is no combustion-supporting measures (oil spraying) adopted, the concentration of dioxins produced may reach 20ngTEQ/Nm3, which is verified by design unit. After fume treatment, most dioxins can be removed, and the emission concentration is not more than 1.0ngTEQ/Nm3. Under the least favorable conditions, if the absorption of active carbon and corresponding filtering device do not work normally, the maximum emission concentration of dioxins at outlet of chimney may reach 11ngTEQ/Nm3. Under this condition, the amount of waste gas is about 100000m3/h, lower than that of normal condition and the emission amount of dioxins is 1.1mgTEQ/h, with the emission time not more than 1 hour. The accidents of this kind are caused by ineffective control over production, too-low temperature of incinerator, and higher CO content in fume. Meanwhile, the possibility that the absorption of active carbon and corresponding filtering device do not work normally is very low.

2.6.3.3 Emission of odorous gas under abnormal operating conditions, such as maintenance of incinerator

The reasons why the prevention and control measures for odor pollution are not implemented effectively are: shutdown of incinerator where the primary fan ceases to extract air from waste pond; air curtain stops to work due to fault; house of waste pond is damaged significantly, where the waste pond is not under closed condition. The first case has the most possibility of occurrence, with one or two cases per year, and the period is 2-4 days. For this project, the three incinerators can’t be repaired simultaneously. In case of accident where the three incinerators stop to work, the odorous gas is mainly produced from waste pit, and the subsequent odorous gas can’t be burned through incinerator. The active carbon deodorization device is proposed to be provided for platform on sidewall of waste pit. The fan will extract the odorous gas from waste pit to the active carbon deodorization device. After deodorization, the gas will be sent to the chimney with height of 80m, and then emitted to the air. During maintenance of incinerator, active carbon deodorization device is designed to be used in this project for deodorization purpose. The active carbon has better capability to absorb odor than any other purification methods. The deodorization rate by active carbon may reach 80%. Meanwhile, the active carbon can purify a plenty of matters which can produced odor, and is suitable for long-term application. The emission of odor pollutants of the project

is shown in 2.6-3. According to the table, the NH3 and H2S meet the requirements of Emission Standard for Odor Pollutants (GB14554-93).

2.6.3.4 Abnormal operation of sewage treatment devices Assuming the fault in sewage treatment devices lasts for 2 days, and that the maximum amount of leachate is 25% of waste treatment capacity, plus the waster for washing unloading room and waste shaft (24t/d), then the total amount of waste water is 274t/d; the designed leachate treatment capacity is 300m3/d. For this project, during construction of leachate treatment station, a regulating pond of 1200m3 is provided for collecting leachate resulting from accidents and for temporarily store waste water. After the fault is removed, the water will be treated to meet requirements and then discharged. In this case, the untreated waste water will not be directly sent to Dagang Sewage Treatment Plant.

Therefore, the project conforms to the industrial policies developed by the State, Jiangsu province and Zhenjiang city.

4.2 Analysis on cleaner production

4.2.1 Necessity of the project The waste incineration project is an environmental protection engineering which is able to solve the problem regarding how to dispose domestic waste in Zhenjiang, and the problem regarding environmental pollution resulting from landfilling of large quantity of waste. With the development of national economy, and continuous expansion of city and increase of population, the domestic waste in Zhenjiang is also increasing. In the domestic waste in Zhenjiang, as the proportion of combustible components rises and water content lows, the heat value of waste will increase; therefore, it is becoming more and more suitable to use incineration to treat waste. After incineration, the amount of waste may be reduced by 70% or more, and volume by 90% or more. Incineration power of waste fully utilizes the heat value in waste. It is an effective waste treatment method in Zhenjiang.

The grate incinerator has the following features: (1) Grate configuration to achieve better mixing effects Angle of declination of grate favorable for mixing and conveying Effective mixing The① movable grate will convey the waste fixed on it to the upper part of waste in front of it, and then continuously mix the waste. After completion of combustion, as the angle of declination upwards become larger, the mixing efficiency is increased. (2) Less leakage of ash from grate and prevention of plugging resulting from ash leakage of grate and avoidance of bonding. As the finish on sides of grates is improved, the gas between the grates is reduced, thus realizing high-pressure primary air. The grate ensures uniform air flow on the waste. Namely, the uniform flow of burning air is obtained through keeping of higher pressure difference, so as to ensure stable burning. (3) Effectively solve the problem in thermal expansivity of grate In order to prevent appearance of gap, the spring device is provided around the inserts to fix grate. Thermal expansion of grate is reduced by spring device.

After recycling of such water in plant, the water resources are saved effectively.

4.3 Summary for analysis on cleaner production The construction of the project conforms to national industrial policies. The project adopts advanced processing equipments and production control technology. The energy consumption, production and emission of pollutants, and pollution control measures reach domestically advanced level, and some index reaches internationally advanced level. After completion and operation of the project, the construction unit is recommended to conduct works relating to cleaner production. The construction unit shall conduct comprehensive check-up on production technology, fume treatment techniques, production operation and management, waste disposal and comprehensive utilization, and analyze each technical index of waste incineration, so as to find out the causes for production and emission of pollutants. By doing this, reasonable proposals on energy-efficient, reduction of pollutant emission and comprehensive utilization of waste may be put forward, thus constituting new measures for cleaner production.

Assessment method Single-item water quality parameter assessment is used here. In assessment of each water quality parameter, the current concentration of certain water quality parameter③ is the average concentration of monitoring value. The formula for calculating pollution index of each factor is:

Sij=Cij/Csj Where, Sij: standard index of type-i pollutant at point j; Cij: monitored average concentration value of type-i pollutant at point j; CSj: standard surface water value of type-i pollutant, mg/L； Of which, dissolved oxygen is:

DOf  DOj SDO, j  DOj s DOf  DOs ≥DO

DOj S DO , j  10  9 DOj

pH:

0.7  pH j S pH , j  pHj≤7.0 0.7  pH Sd pH  0.7 S  j pH >7.0 pH, j pH  0.7 j Su

Where, SpHj: standard index of water quality parameter (pH) at point j; pHj: pH value at point j; pHsu: upper limit of pH value stipulated in Standards for Surface Water Quality pHsd: Lower limit of pH value stipulated in Standards for Surface Water Quality

江苏省环境科学研究院 8 Jiangsu Provincial Academy of Environmental Science

SDOj: standard index of water quality parameter (DO) at point j; DOf: saturation value of dissolved oxygen under water temperature, mg/L； DOj: measured value of dissolved oxygen, mg/L； DOs: standard value of dissolved oxygen, mg/L； Tj: water temperature at point j, t . Assessment results and analysis Single factor index is used for evaluating status℃ of quality of surface water, as shown in table 5.3-2. Among section index, SS and total phosphorus surpass the set standard, and others conform to the Standards of Surface Water Quality. The over-limit of SS is caused by large flow from upstream during monitoring period, and rapid flow of Yangtze River, resulting in too many suspended particles. The over-limit of total phosphorus is the reason why some domestic sewage in the assessment range is not to be inflow.

6.1.2 Prediction mode Description of prediction mode The atmospheric assessment is defined as Level II, and the prediction was made by AERMOD model according to the Atmospheric Environment for the Technical Guidelines for Noise Impact Assessment (HJ2.2-2008).

AERMOD was developed by American Regulatory Model Improvement Committee (AMRMIC) which was jointly incorporated by American National Environmental Protection Agency and American Meteorological Society. This system is based on the dispersion calculation on the assumption that the concentration of pollutants is in a way subject to

江苏省环境科学研究院 16 Jiangsu Provincial Academy of Environmental Science

Gaussian distribution. The model system applies to multi-source emission (including point sources, non-point sources and volume sources as well as simulation and prediction of a number of emissions and dispersions of rural environment and urban environment, flat landforms and complex landforms, ground sources and overhead sources. The operation flow of AERMOD model is shown in fig. 6.1-3 below.

Fig 6.1-3 Flow chart of AERMOD system Source of terrain data We used the SRTM3 digital elevation terrain data of USGS for our prediction. The precision is 3arc about 90m. The terrain data used for our prediction is in hgt and numbered N32E119. The sketch of topography is shown in figure 5.1-4 below.

Sector and surface parameters According to the field investigation, we divide the proposed site of the Project into 3 sectors. Surface parameters of each of the sectors are detailed in table 6.1-4 below. Table 6.1-4 Surface parameters No Type of land utilization Albedo Bowen ratio Roughness 1 City 0.2075 1.625 1 2 Arable land 0.28 0.75 0.0725 3 Arable land 0.28 0.75 0.0725 Building downwash As specified by US Environmental Protection Agency (EPA) for building downwash, calculation of the air quality impact from any new or existing chimney that is lower than GEP (good engineering practice) height should include the impact from the lee vortex and the wake from the surrounding buildings. The EPA correction formula for calculating the GEP height is: GEP height =H+1.5L Where: H—height of the building (the highest point from the ground level); L—the smaller of the building height (BH) and the Projected building width (PBW); GEP—best engineering practice. Height and Projected width of main buildings in the Project are detailed in table 6.1-5 below.

From the table above, SO2, NO2, HCl and NH3 emission from the Project when complete will not cause much impact on the ambient air quality. The max added values in the average hourly concentrations are 0.014mg/m3, 0.027mg/m3, 0.005mg/m3 and 0.190mg/m3 respectively, accounting for 2.8%, 11.1%, 10% and 94.8% respectively of the assessment standard, showing that they conform to the assessment standard.

HCl and NH3 of the environmental sensitive protection targets, when stacked with the present monitored hourly concentrations, still conform to the assessment standard.  Summary of average hourly concentration

In a word, the SO2, NO2, HCl and NH3 emission from the Project when complete will not cause significant impact on the ambient air quality. The max increases in the average hourly concentrations are 0.014mg/m3, 0.027mg/m3, 0.005mg/m3 and 0.190mg/m3 respectively, accounting for 2.8%, 11.1%, 10% and 94.8% of the assessment standard, which conform to the assessment standard; the predicted max average hourly ground level concentrations, when stacked with the present monitored values, still conform to the assessment standard. So, the impact of the Project on the average hourly concentrations of the ambient air and protection targets conform to the assessment standard when it is complete.

From the table above, the emission of SO2, NO2、, PM10, HCl and Pb after project completes will not cause much impact on the ambient air quality. The max increases in the average daily concentrations are 0.0036mg/m3, 0.0068mg/m3, 0.0988mg/m3, 0.0013mg/m3 and 0.00002mg/m3 respectively, accounting for 2.4%, 5.6%, 65.8%, 8.5% and 3.0% of the assessment standard respectively.

From the table above, the predicted max average daily concentrations of SO2, NO2, PM10, HCl and Pb, when stacked with the present measured daily concentrations of the environment and contribution from other approved and to-be-built sources in the area, will still conform to the ambient air quality standard for class II.  Summary of average daily concentration From the above, the SO2, NO2, PM10, HCl and Pb emission from the Project when complete will not cause much impact on the ambient air quality. The max increases in the average daily concentrations are 0.0036mg/m3, 0.0068mg/m3, 0.0988mg/m3, 0.0013mg/m3 and 0.00002mg/m3 respectively, accounting for 2.4%, 5.6%, 65.8%, 8.5% and 3.0% respectively of the assessment standard; the predicted max average daily ground level concentration, when stacked with the present measured daily concentrations of the environment and contribution from other approved and to-be-built sources in the area, will still conform to the ambient air quality standard. Therefore, the impact of the Project when complete conforms to the assessment standard for the average daily concentrations of pollutants in the ambient air. Prediction and analysis of average annual concentration We used AERMOD model to predict the Project, under long-term meteorology, the average annual ground level concentrations in the assessment scope are detailed in table 6.1-17 below.

The SO2, NO2, PM10, Pb and dioxin emission from the Project when complete will not cause much impact on the ambient air quality. The max increases in the average annual concentrations are 0.0004mg/m3, 0.0007mg/m3, 0.0157mg/m3, 0.000002mg/m3 and 0.0002pg/m3 respectively, accounting for 0.6%, 0.9%, 15.7%, 0.2% and 0.04% respectively of the assessment standard. The predicted max average annual ground level concentrations of

SO2, NO2, PM10, Pb and dioxins of the environmental sensitive targets, when stacked with the present measured daily concentrations of the environment and contribution from other approved and to-be-built sources in the area, will still conform to the ambient air quality standard. Therefore, the impact of the Project when complete conforms to the assessment standard for the average daily concentrations of pollutants in the ambient air.

The predicted average annual concentration distribution of SO2, NO2, PM10, Pb and dioxins at the grid is detailed in figures 6.1-15 to 6.1-19 below.

Prediction and analysis of average hourly concentration of abnormal emission Critical parts of the semidry reaction tower of the Project like the rotary atomizer, active carbon ejector system and bag dedusters are all furnished with standby units to avoid any unusual conditions that may degrade the flue treatment plant. As the 3 incinerators of the Project will be overhauled in turn, there will be no unusual conditions when all the 3 incinerators are out of service and prevent the incineration of the odor in the waste pit in the incinerators. According to our analysis of the Project, unusual conditions of the Project mainly include considerable output of dioxins during the firing (closing) of the incinerator. During the startup (rise of temperature) of the incinerator, the incinerator will take about 2~4 hours from cold state to normal operation of the flue treatment plant (rise of temperature). The normal service temperature of the incinerator is above 850℃. Theoretically, no dioxin will be produced when the fumes stays up to 2 seconds. However, dioxin may be produced during the startup (rise of temperature) and closing (shut-off) of the incinerator. According to the testing result of the waste incinerators of six companies under unusual conditions in England, the concentration of dioxins at the outlet of the incinerator during the startup is 2~3 times higher than normal conditions. As dioxins are highly toxic, to be more stringent, we assumed the concentration of dioxins under unusual conditions of firing (closing) is 10 times that under normal conditions, and then unusual source intensity of dioxins is as shown in table 6.1-18 below. Table 6.1-18 Parameters of intensity of abnormal emission sources Height Equivalent X Y above Fumes Emission Height inner Temperature Description Pollutant coordinate coordinate sea volume velocity (m) diameter (K) (m) (m) level (Nm3/s) (g/s) (m) (m) Incinerator Dioxin 745407.6 3561321.5 19.3 50.8333 50.83e-9 80 3.45 417 fumes The top 10 max average hourly concentrations during the firing (closing) of the incinerator are listed in table 6.1-19 below. The max average daily concentrations at the concerned points are listed in table 6.1-20 below. (As only the average annual concentration standard is available for dioxins, the hourly average concentration is rated three times the average concentration limit specified in the Technical Guidelines for Noise Impact Assessment—Atmospheric Environment (HJ2.2-2008), i.e. 1.8pg/m3.

Though this is not out of the standard, the impact of the Project on the average hourly concentration of dioxins in the ambient environment is largely different from normal emission. To mitigate the impact on the ambient air quality, and according to our prediction result, we recommend that the owner take the following measures: Actuate the oil ejection combustion system when firing the incinerator and raise the incinerator temperature to above 850℃; As the max average hourly concentration of dioxins mainly occurs at 2:00- 6:00 of the day in the area and at 2:00-11:00 at the concerned points, it is necessary to evade early morning and morning hours when firing (closing) the incinerator of the Project; Check the flue treatment plant before firing (closing) the incinerator and make sure it provides normal service.

6.1.6 Analysis of up-to-standard concentration at the boundary

The predicted max increases in hourly concentrations of NH3, H2S and particles, when stacked with the present monitored values of the proposed site, all the values conform to the assessment standard for the concentration at the boundary. The stacked values are listed in table 6.1-21 below. The “max concentration outside the boundary the max increase in the hourly concentration + the present monitored value”, proving that the boundary concentrations of NH3 and H2S conform to the Emission Standard for Odor Pollutants, and the boundary concentration of particles conforms to the Emission Standard for Odor Pollutants. Table 6.1-21 Analysis of concentration at the boundary (mg/m3)

Note: H2S and particles are predicted from estimation mode; NH3 is predicted from AERMOD mode.

6.1.7 Atmospheric environmental protection distance Atmospheric environmental protection distance: To safeguard people’s health and mitigate the environmental impact of atmospheric pollution on the residential points under the normal emission, an environmental protection distance is defined outside the plant boundary of the Project. In our assessment, we used the atmospheric environmental protection distance in the recommended model to calculate the atmospheric environmental protection distance of the unorganized sources. The atmospheric environmental protection distances of the waste pit, leachate treatment station and fly ash solidification plant of the Project area calculated separately. The calculation parameters and result are listed in table 6.1-22 below. Table 6.1-22 Calculation parameters and result of atmospheric environmental protection distance Emission Hourly Location of Length Width Height Calculation Pollutant volume standard pollutant (m) (m) (m) result (m) (kg/h) (mg/m3) NH 0.0069 0.20 Not necessary Waste pit 3 50 40 8 H2S 0.0007 0.01 Not necessary Leachate NH3 0.133 0.20 Not necessary treatment 15 14.7 6 H S 0.000412 0.01 Not necessary station 2 Fly ash solidification Dust 0.244 20 18 8 0.50 Not necessary plant ◆Analogy analysis As a common practice, the environmental protection distance of different waste power plants in China (with the daily capacity of 400~1000t/d) is between 200~300m, analogically compared to the environmental protection distance of 200m for Taicang Waste Incineration Power Plant (with the capacity of 600t/d), 300m for Changzhou Waste Power Plant (with the capacity of 700t/d) and 300m for Wuxi Waste Power Plant (with the capacity of 2000t/d). From this, and with reference to Document HF [2008] 82, the environmental protection distance of the Project is 300m outside the plant boundary as shown in figure 2.1-1 below. The existing environmental sensitive target within the environmental protection distance includes Fangquan Group of Dianshang Village, which is now under relocation and Zhenjiang New District Administration Committee promises to complete the relocation in 2009. No residential point, school, hospital or other sensitive target is permitted within the environmental protection distance, nor should any food processing, drug, cosmetic or Project requiring high ambient air quality be built there. The local government should plan and control construction within 1000m outside the boundary of the Project and keep off any new school, hospital, residential point or other environmental sensitive target.

6.1.8 Demonstration of chimney height

The height of the chimney used in waste incineration not only decides the input of the construction fund, but more importantly, related to the transmission distance and landing concentration of the flue gases from the incinerated waste. The proposed chimney of the Project is 80m high, which conforms to the Standard for Pollution Control on the Domestic Waste Incineration (GB18485-2001). According to our prediction, under normal conditions, as an 80m-high chimney is used, the atmospheric pollutants from the Project will not cause significant impact on the ambient environment. This, when stacked with the present monitored values and the predicted values of other approved and to-be-built Projects in the area, all the pollution factors in the assessment area conform to the assessment standard. So, the Project will not degrade the existing ambient air functions of the assessment area when it is complete. Buildings within a 200m radius from the chimney of the Project are 41m high. As the chimney is 39m higher than them, it conforms to the requirement of “more than 5m above the buildings within a 200m radius around it”. From this, it is reasonable that the Project incorporates an 80m high chimney.

6.1.9 Summary Prediction of ambient air impact from unorganized odor emission

Prediction shows that the unorganized emission of NH3 from the waste pit and leachate treatment station of the Project conforms to the assessment standard for the average hourly concentrations and the unorganized emission of NH3 and H2S conforms to the standard limit for emission at the boundary. Prediction of ambient air impact from incinerator fumes under normal condition Average hourly concentration

The max increases in the average hourly concentrations of SO2, NO2, HCl and NH3 emissionᬅ from the Project when complete are 0.014mg/m3, 0.027mg/m3, 0.005mg/m3 and 0.190mg/m3 respectively, which conform to the assessment standard; the predicted max hourly concentrations of SO2, NO2, HCl and NH3 at the concerned points, when stacked with the present monitored values, also conform to the assessment standard. Average daily concentration

The max increases in the average daily concentrations of SO2, NO2, PM10, HCl and Pb emission from the Project when complete are 0.0036mg/m3, 0.0068mg/m3, 0.0988mg/m3, 0.0013mg/m3 and 0.00002mg/m3 respectively, which conform to the assessment standard; the predicted max average daily concentrations of SO2, NO2, PM10, HCl and Pb at the concerned points, when stacked with the present monitored values and the predicted values of other approved and to-be-built Projects in the area, also conform to the assessment standard. Average annual concentration

The max increases in the average concentrations of SO2, NO2, PM10, Pb and dioxin emissions from the Project when complete are 0.0004mg/m3, 0.0007mg/m3, 0.0157mg/m3, 0.000002mg/m3 and 0.0002pg/m3 respectively, which conform to the assessment standard.

The predicted max average annual ground level concentrations of SO2, NO2, PM10, Pb and dioxin at the concerned points, when stacked with the predicted values of other approved and to-be-built Projects in the area, also conform to the assessment standard. From this, the Project will not cause significant impact on the ambient air quality under normal emission. Prediction of ambient air impact from incinerator waste gases under the abnormal emission The max average hourly concentration of dioxins from the Project under abnormal emission is 0.083pg/m3, which is 4.6% of the standard and conforms to the assessment standard though it is largely different from normal conditions. To mitigate the impact on the ambient air quality, we recommend that the owner take the following measures: Actuate the oil ejection combustion system when firing the incinerator and raise the incinerator temperature to above 850℃; Avoid firing (closing) the incinerator of the Project early in the morning or during the morning hours. Check the flue treatment plant before firing (closing) the incinerator. width of protection zone for atmospheric environment The width of protection zone for atmospheric environment is 300m outside the boundary. All the residents within the protection distance should leave before the Project is put into production. Keep any residential point, school, hospital or other sensitive target from the land within the environmental protection distance, nor should any food processing, drug or cosmetic Project requiring high air environmental quality be built inside the area. The local government should plan and control construction within 1000m outside the boundary of the Project and keep off any new school, hospital, residential point or other environmental sensitive target. In consideration of ambient air impact, the 80m chimney in the Project is feasible.

6.2 Analysis of water environmental impact

The wastewater in the proposed Project will be centrally treated in Dagang Sewage Treatment Plant. According to the environmental impact assessment of Dagang Sewage Treatment Plant: wastewater emission in the low season will develop a compound area of 0.102-0.491mg/L increase of COD 100m downstream 20m off the bank at falls and a compound area of 0.108-0.649mg/L of COD 100 upstream 20m off the bank at rises. And the accumulative annual average COD concentration at the Yangtze at Dagang reach is 2.7mg/L. When the base value is stacked, there is no significant change in the water quality. The additional wastewater emission from the Project is within an acceptable level for Dagang Sewage Treatment Plant. Therefore, the emission of the wastewater from the Project will cause little impact on the quality of the surface water after treated at Dagang Sewage Treatment Plant. 6.3 Assessment of sound impact

6.3.1 Noise sources Noises of the proposed Project mainly include noises from the mechanical equipment, aerodynamic noises and noises from the transport plants. High-noise equipment in the Project includes the turbo-generator unit, the FD fans, ID fans, mixers, boiler steam exhauster and cooling tower. The main high-noise source—the turbines, are installed within the same main workshop so that the main workshop becomes a vertical noise source. The impact was predicted by the non-point sources as a whole. The cooling tower produces continuous low-frequency noises. The boiler steam exhausting noise is a high-frequency intermittent noise source and can be as high as 110dB(A) when in service. This causes considerable impact on the ambient environment and covers a long distance. According to the analysis of the Project, main sound source equipment and their noise levels involved in the Project are detailed in table 6.3-1 below. Table 6.3-1 Production, control and emission of noises (dB (A)) Sound level at Level of which is 1m No. Description Qty Shops sound Control measures outside the source shop Sound insulation to the Generator workshops; adjust equipment 1 2 Turbine room 95~100 60 units to keep dynamic balance (damping); install muffler Cooling 2 3 85 Arrange properly 85 tower Install muffler; sound 3 Mixer 3 Waste pit 80~90 55 insulation to building Fumes Install sound insulation casing, 4 ID fan 3 85 55 purification room muffler Install sound insulation casing, 5 FD fan 3 Passage 85~90 55 muffler Integral pump Make pump damping; 6 Pump 28 95 55 room sound-proof cofferdam Air Air Compressor 7 3 90 Sound insulation, damping 60 compressor room Use low-noise safe valve Boiler control valve equipment, 8 3 Incineration room 95~110 80 exhaust install muffler and take damping measures

6.3.2 Prediction of sound environmental impact According to the characteristics of the sound sources and environment, we calculated the sound level of the sources to the prediction points and then predicted the impact degree of the Project on the ambient sound environment when complete by stacking them over the present values. Prediction mode As the main workshop of the power plant is fairly high, we took the exterior wall of the workshop as the non-point source. Assume the distance to the receiving point is r, the workshop height is a, and the workshop length is b, our calculation of the sound pressure level at the receiving point close to the wall surface at r O.C. (including only the distance attenuation) is shown below: Where ra/π, the sound pressure level in the noise transmission is not related to the distance and there’s no significant attenuation; The sound source area can be approximately the line source, and the prediction formula is:

L(r)＝L(r0)-10log(r/r0)-ΔL Where r>b/π, the sound source can be approximately deemed a point source: The formula for the sound source attenuation of point sources:

L(r)＝L(r0)-20log(r/r0)-ΔL Formula for stacking multi-source noises: L＝10lg(∑100.1Li) Where: Sound level A equivalent at r from the sound source, dB (A);

Sound level A equivalent at r0 from the sound source, dB (A); ΔL——Attenuation from all factors (including that from covering, air absorption, ground effect), dB(A); R—— Distance of the noise source from the concerned point, m;

r0——Distance from the noise source, m; L——Total equivalent A sound pressure level; Li——The sound pressure level of sound source No. i; N——Number of sound sources. Prediction result We calculated the sound levels at the monitoring points of the boundary with the above prediction mode, and stack them over the present noise levels to predict their impact on the sound environment at the boundary. The result is detailed in table 6.3-2 below.

There is no environmental sensitive target within 300m outside the plant boundary and there will be no disturbance to the public.

6.3.3 Assessment standard The boundary noise emission standard of the proposed Project is rated at classes 3 and 4 of Emission Standard for Industrial Enterprises Noise at the Boundary (GB12348—2008).

6.3.4 Assessment result The boundary noise of the proposed Project will conform to the standard at all the points when complete, and there is no environmental sensitive target within 300m outside the boundary, proving that the Project will not cause noise disturbance to the public when complete.

6.4 Analysis of soil and groundwater impact

From the main hazardous content in the solid wastes of the Project, the solid wastes contain relatively high heavy metal substances and organic substances. Where no stacking point for the wastes or no waste treatment with proper leakage protection is incorporated in the design, it is impossible that the hazardous components will produce high temperature and toxic liquid from weathering, rain dissolution or surface runoff and come into the soil, kill the microorganisms in the soil, destruct the balance of the microorganisms with the surrounding environment composition system and lead to denudation of the land or, for arable land, reduction of yield over large areas. What’s worse, once these water contents come into the groundwater through the soil, the quality of the groundwater will also be polluted. In the Project, the solid wastes will be sorted, collected and stored separately. Places for storage purposes will be furnished with preventive measures against scattering, erosion and leakage. The solid wastes will be colleted, stored and transported by appointed persons. Pollution prevention and emergency accident measures will be provided for hazardous waste transfer together with strict procedures for waste transport. When all these measures are put into effect, the solid wastes in the Project will cause minimal impact on the soil and groundwater. In the Project, both the waste pit and the leachate sump will incorporate courses of antiseepage material on the bottom and the sidewall, which help minimize the impact on the soil and ground water from the leachate. Incineration flue produced during the operation of the Project contains heavy metals and dioxin. The heavy metals will accumulate in the soil and change the physiochemical property of the soil and degrade its fertileness. It is also possible that these metals will come into the food chain through the crops and affect people’s health. Dioxin, on the other side, will break up when exposed in the sun but will be half-decayed for more than 10 years when buried in the soil and might pollute the soil. The Project will incorporate an associated fumes treatment plant together with stringent control measures to limit the emission of heavy metals and dioxin and keep the soil environmental quality from deteriorating.

6.5 Analysis of eco-environmental impact

Impact on local regional climate When the Project is complete, part of the ground inside the plant will be cement hardened and part will be artificially planted. As the exposed cement ground provides small volume and high reaction rate, there is almost no heat depletion from evaporation. The bedding level is high in the temperature and quick in heating, it forms a “hot wave zone”. As the Project does not involve large land coverage, there is little impact on the local climate. Impact on vegetation Vegetation of the Project locality mainly consists of artificial vegetation, including farmland and woods. Impact of the Project on the plant resources mainly includes reduction in the plant coverage and number of life forms in some of the areas due to the land occupation by the Project. However, as the Project does not involve large land coverage, there is little impact on the unit lifeforms of the entire environment or any loss of the flora species. Impact on agricultural plants Pollutants from waste incineration mainly include atmospheric pollutants like smoke, SO2 and NO2. Atmospheric pollutants will intrude or adhere to plant leaves and damage the tissue of the leaves, destruct their normal functions, deteriorate the photosynthesis and affect the growth and yield. What’s worse, the all the atmospheric pollutants impose compound action to plants. For example, combined action of SO2 and nitrogen dioxides will be much more hazardous than any single gas alone. Flue gases of the Project will produce much lower pollutant emission after treated in the waste gas treatment plant. Besides, the waste gas is emitted through an 80m-high chimney resulting in fairly low concentration of pollutants is fairly low when landed on the ground, there is little impact on the nearby agricultural crops from the conformity waste gases.

6.6 Analysis of environmental impact during the construction

During the construction, impact factors in the construction period of the plant include construction of the main workshop, office building, auxiliary facilities and roads to the plant, installation of the equipment, transport and stacking of the decoration materials and cleaning of the construction site.

6.6.1 Impact factors and control measures inside the plant during the construction 6.6.1.1 Impact factors during the construction (1) Noise Noises during the construction mainly include noises from construction machines and transport vehicles. Our analogy analysis show that the noise levels of these construction machines range between 75~115dB(A) and the combined level is above 90dB(A) under most circumstances. This will cause certain impact on the construction personnel and the ambient environment. (2) Dust Dust mainly comes from earth excavation and filling, concrete blending, earth taking from the material quarries, stacking of spoils, handling of bulk cement and vehicle transport. Pollutants mainly include TSP. Dust from earth-rock excavation, concrete blending, earth taking from the material quarries and stacking of spoils is mainly emitted intermittently. Dust and waste gases from handling of bulk cement, vehicle transport and work of construction equipment are emitted in a linear way. (3) Solid waste Solid wastes from the construction include residues and debris from earth-rock excavation, material spoilage from material transport including sandstone and concrete; spoilage and discarding of rock, slag and building materials during the pavement finishing and domestic waste from the construction personnel. (4) Wastewater Construction wastewater mainly consists of pit drainage and alkali wastewater from concrete blending and curing as well as domestic sewage from the construction personnel.

6.6.1.2 Control measures against impact during the construction To mitigate impact on the ambient environment during the construction, it is advisable to take the following control measures to minimize any negative impact. (1) Control measures against construction noise Control the noises of the construction machines during the construction. Take protective measures for the construction personnel where control is impossible. Use automobiles conforming to the permissible noise limit for motor vehicles as transport tools. Concrete control measures include: Schedule the construction properly: When making a construction schedule, try best to avoid simultaneous operation of a large number of high-noise machines, avoid ᬅ the time periods when the ambient environment is sensitive to noises reduce construction during nighttime. Try to speed up construction and shorten the whole construction duration. Lower the sound level of the equipment: Use low-noise types as practically possible when selecting the construction equipment; reduce the noise level by ᬆ incorporating a muffler in the exhaust pipe and isolating the vibration parts of the engines; repair and maintain powered machines, reduce the noise from vibration of parts exposed to frequent looseness; shut down any equipment that becomes unused; slow down the transport vehicle and minimize whistling when approaching the site. Build temporary sound barriers: Try to enclose any mechanical equipment that is relatively fixed in the position if it can be operated inside the shed. Where ᬇ necessary, build single-side sound barrier. (2) Control measures against dust and exhaust gases Spray water regularly every day in the construction site to prevent dust. Spray more water and more frequently on high-wind days. ᬅ Clean and wash the transport accesses inside the construction site to control dust from vehicle travels. ᬆ Drive the transport vehicles at low speed or limited speed when approaching the construction site to control the dust production. ᬇ Select proper places for stacking the rockwork, preferably places other than upstream of the housing area of the construction personnel. Install the concrete ᬈ mixer inside the shed with isolation enclosure and windshield around it. Remove any cement or sand spoil from the mixing from time to time. Move away the construction earth pile in a timely manner. Cover the transport vehicles to minimize spoilage along the way. Avoid stacking any dusty materials like cement, sand or lime in the open. Cover any dusty material coming in and out of the construction site and ᬉ transport it in vehicles with windshield. ᬊ Construction should keep clean the road environment in front of the site entrance and clean up any spoil from the earth stack or building material. ᬋ Pay attention to the waste gas pollution from the construction machines and vehicles. Make sure that they use high-performance clean fuels to the national ᬌ standard only and incorporate a tail gas purifier to minimize emission of waste gas pollutants. (3) Control measures against solid waste Avoid earth spoilage when carrying earth on the vehicles. Remove any mud on the wheels before the vehicle leaves the construction site and avoid covering ᬅ the ground with earth piles along the way that will affect the environmental cleanness. Stack the construction rubbish from the construction process at fixed points and remove it in time. The Project owner and the transport department should ᬆ educate their drivers on occupational ethics, make sure they travel along the specified route and check up the execution on random basis. Sort and reclaim the domestic waste to remove it every day and avoid discarding it randomly. ᬇ Stop work for any toxic or hazardous waste discovered during the construction,

ᬈ contact the local environmental authority immediately and do not resume work until such waste is treated. (4) Control measures against wastewater Both the Project owner and the contractor should attach importance to the emission management of the construction sewage, reject any untreated or unorganized emission of any sewage and prevent impact on the environmental from the emission of the construction sewage. Measures taken mainly include: Build construction drains to ensure orderly pit drainage into the nearby rivers. Wastewater from concrete blending and curing mainly contains suspended ᬅ substances, silicates and oils. A wastewater sedimentation pond will be built at ᬆ the construction site to collect the wastewater and treat it. Wastewater will be reused after it is treated in the sedimentation pond and will not be discharged outside. Domestic sewage mainly contains SS, COD and animal/plant oils. A central sewage collection facility will be furnished at the temporary housing area of the ᬇ construction personnel to remove the rejecta and carry it away for use as farmland compost. (5) Control measures for external roads during construction Try to limit ground opening during the construction as appropriate and plant vegetation in the places where work is complete within the shortest time ᬅ possible. Take measures to prevent oils or fuels from polluting the soil or the river courses. ᬆ Keep strict management of building rubbish. Make sure that it is stacked at designated points and treated properly. (6)ᬇ Other measures Handle the oils and chemicals in enclosed containers. Reinforce management during the transport and reject transport pollution. Coordinate with the traffic authority about the equipment transport, use the vehicles in the proper way, transport in a centrally, evade peak hours and mitigate the impact on traffic.

6.6.2 Analysis of environmental impact inside the plant during the construction Our analysis of the impact on the ambient environment during the construction period is detailed below provided that preventive measures are taken against the pollution sources during the construction period:

6.6.2.1 Analysis of environmental impact from construction noise Noise levels of machines in service during the construction are detailed in table 6.6-1 below. Table 6.6-1 Average sound level A equivalent of main mechanical noises during the construction Construction Noise Construction Level/dB(A) Noise source Level/dB(A) stage source stage Excavator 78~96 Concrete mixer 100~110 Drill 105 Concrete pump 90~100 Earth & rock Air Vibrator 100~105 works 75~85 compressor Pile driver 95~100 Electric saw 100~110 Electric 100~115 Bottom slab Electric 90~95 drill & structure welding machine Decoration, Electric 100~105 Air compressor 75~85 installation hammer Toothless 105 saw As the construction consists of outdoor work in general without sound insulation or mitigation measures, the noise will go far and cover a large area. The sound level of the construction stages is 75~115dB(A). As the noise at the construction site mainly consists of high-noise construction machines, and there are a large number of machines in service at the site during the construction with the sound level of individual machines usually higher than 90dB(A), plus the frequent relocation of the machines inside the construction site and the fluctuation of the number of machines in service at different times of the same construction period, it is hardly possible to predict the noise levels of the construction site at the boundary.

For different construction periods of the plant, different standards have been specified in the Noise Limits for Construction Site (GB12523-90), as part of which nighttime construction is prohibited during the piling period. With reference to the noise impact prediction of similar construction machines, the impact scope of construction machines is 60m for daytime and 180m for nighttime.

While all the residents within the 300m limit will have been relocated before the construction of the Project and nearby villages are quite far away from the construction site of the Project, it is still necessary to provide preventive measures for both daytime and nighttime construction and minimize the impact on the nearby residents.

6.6.2.2Analysis of atmospheric environmental impact during the construction Atmospheric pollution sources during the construction period mainly consist of TSP. As the surface structure will be destructed during the trench excavation, pipe burying and pavement installation, there will be dust from the ground that will pollute the environment. Earth stacking and outdoor earth-rock stacks will also produce dust. And the transport increase during the construction will also contribute to the dust along the way. The environmental impact of dust from earth excavation and earth stacking during the construction is temporary and will end along the construction. Transport dust is limited generally within 30m of the source road and the degree of dust varies from road to road, with the TSP of earth roads 2~3 times higher than cement roads. For the construction dust, it is necessary to spray water on regular basis. As most of nearby areas around the construction site are either unused land or farmland, there is limited impact from the construction dust. The secondary pollution sources that will affect the atmospheric environment during the construction include waste gases from the construction machines and transport vehicles when burning diesel oil and gasoline. The tail gases from the construction vehicles should conform to the standard for tail gas emission. However, as the construction period is short and limited in a small site, the waste gas pollution is both in a small range and temporary and will not cause impact on the ambient environment.

6.6.2.3 Environmental impact from solid waste Solid wastes during the construction mainly includes domestic waste from the construction personnel, spoils from earth excavation and debris; material spoilage from material conveyance including sandstone and concrete; spoilage and discarding of rock, slag and building materials during the pavement finishing. As the Project mainly consists of construction within the plant boundary, and solid wastes are stacked and managed at fixed points, there is minimal impact on the ambient environment.

In addition, mud spoiled during the loading and transport and that attached to the wheels will also cover the transport road with mud. So it is important to pay attention to the disposal of the earth stacked on the construction road and clean it up from time to time.

Demostic waste during the construction should be cleaned up in a timely manner. The municipal environmental department will collect and transport the domestic waste.

6.6.2.4 Analysis of impact on water environment The little pit drainage in the Project mainly includes groundwater, which will be directed through open drains to the nearby rivers. Wastewater from concrete blending and curing will be collected centrally and reused after neutralized in the sedimentation pond without discharging outside. Central collection facilities will be built for domestic sewage in the temporary housing area of the construction personnel to clean up and carry away the rejecta regulary for use as farmland compost. In a word, there is very little emission of wastewater during the construction of the Project and there is little impact on the nearby surface water environment.

6.6.3 Summary As there might be temporary and local impact on the ambient environment from the noise, wastewater, dust and solid wastes during the construction period from different construction activities, it is necessary to put into effect the pollution control measures and minimize the environmental impact during the construction period.

6.7 Analysis of waste transport impact and recommended measures

6.7.1 Collection scope and transport route of waste The service of Waste Incineration Power Plant in Zhenjiang covers Jingkou District, Runzhou District, Dantu District, New District of Zhenjiang City and part of Danyang City. The transport routes are detailed in table 6.7-1 and figure 6.7-1 below. Table 6.7-1 Waste collection and transport route Location Transfer station Waste carrier route Dongmenpo Dongmenpo—Zhengdong Road—Mengxi Road—Dingmaoqiao Road— Jingshier Road—Yanjiang Highway—Waste incineration plant Xiahetou Jiuhai Street—Zhengdong Road—Mengxi Road—Dingmaoqiao Road— Jingshier Road—Yangjiang Highway—Waste incineration plant Jingkou Jiangbinxincun Jiangbinxincun—Dongwu Road—Guyang Road—Zongze Road—Xuefu Road District —Jingshier Road—Yangjiang Highway—Waste incineration plant Huashanwan Huashanwan—Taohuawu—Xuefu Road—Jingshier Road—Yanjiang Highway —Waste incineration plant Jingkou Road Jingkou Road—Xuefu Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Jinxing Kuangji Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway— Waste incineration plant Zhonghuazhi Zhonghuazhi Road—Dianli Road—Yunhe Road—Tianqiaozhi Road Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway--Waste incineration plant Yuntaishan Paiwan—Zhongshanxi Road—Yunhe Road—Tianqiaozhi Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Runshoushan Runzhoushan Road—Zhongshanxi Road—Yunhe Road—Tianqiaozhi Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway--Waste Runzhou incineration plant District Taoyuan Taoyuan—Zhongshanbei Road—Zhongshanxi Road—Yunhe Road—Tiaoqiaozhi Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Lijiashan Lijiadashan—Huangshannan Road—Nanxu Avenue—Tianqiao Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Sanmaogong Zhufang Road, Nanxu Avenue—Tianqiao Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Linyin Road Linyin Road—Nanxu Avenue—Tianqiao Road—Dingmaoqiao Road—Jingshier Road—Yanjiang Highway—Waste incineration plant Dantu New City Dantu New District—National Highway 312—Yanjiang Highway—Waste incineration plant Shangdang Shangdang—Zhenrong Road—Yanjiang Highway—Waste incineration plant Baonian Baonian—Zhengrong Road—Yanjiang Highway—Waste incineration plant Dantu Xinfeng XInfeng—Yanjiang Highway—Waste incineration plant District Gaozi Gaozi—National Highway 312—Yanjiang Highway—Waste incineration plant Shiye Shiye—Changjiang Road—Zhengda Highway—Waste incineration plant Gaoqiao Gaoqiqo—Dagang—Waste incineration plant Jiangxin Jianxin—Jianbi—Waste incineration plant Dagang Xinggangxi Road—Zhenda Highway—Waste incineration plant Zhenjiang Nanjingsan Road Nanweisan Road Jingshier Road Yanjiang Meilinwan — — — New Highway—Waste incineration plant District Weiliu Road Jing 9th Road Weisan Road Jingshier Road Yanjiang Weiliu Road — — — — Highway—Waste incineration plant Beierhuan Beierhuan Road—Shimendiyi Road—Gedan Highway—Waste incineration plant Quanfu Road Zhonghshan Road—Chenghe Road—Beierhuan Road—Shimendiyi Road—Gedan Highway—Waste incineration plant Huayuan Road Chenghe Road—Beierhuan Road—Shimendiyi Road—Gedan Highway— Waste incineration plant Huanan Huaxi Road—Huayang Road—Chenghe Road—Beierhuan Road—Gedan Danyang HIghway—Waste incineration plant City Nanmen Nanhuan Road—Huayang Road—Chenghe Road—Beierhuan Road—Shimendiyi Road—Gedan HIghway—Waste incineration plant Zhaojiahan Huayang Road—Chenghe Road—Beierhuan Road—Shimendiyi Road—Gedan HIghway—Waste incineration plant Situ Town Danfu Highway—Xihuan Road—Beierhuan Road—Shimendiyi Road—Gedan Highway—Waste incineration plant Picheng Town Danpi Highway—Gedan Highway—Waste incineration plant Houxiang Town Provincial Highway 338—Gedan Highway—Waste incineration plant

6.7.2 Analysis of waste transport impact and recommended measures

6.7.2.1 Noise impact The noise source of waste carriers is about 85dB(A). As calculated, where there is no obstacle on either side of the road, the equivalent continuous sound level 6m from the roadside is 69dB(A). The traffic noise is within the equivalent continuous sound level on both sides of traffic trunks of lower than 70dB (A) for the daytime, but is higher than the standard of 55dB(A) for nighttime. The equivalent continuous sound level 30m from the highway is 55dB(A). This shows that the traffic noise 30m from both sides of the access road to the plant is within the equivalent continuous sound level limit of lower than 55dB(A) on both sides of traffic trunks for both daytime and nighttime. So far, as there are offices and residential points within 30m of the roadsides, they will be exposed to the noise impact from the waste carriers.

6.7.2.2 Cacosmia and environmental sanitation impact Proteins of animals and plants in Nature produce cacosmia pollutants in their bacteria decomposition, and the sulfureted hydrogen, ammonia and methyl mercaptan odors from the piled and stored waste also produce unpleasant odors. Presently, Zhenjiang has its own waste compression station. As the waste is compressed before it is carried away in fully enclosed waste carriers, it is basically possible to control leakage of odor, waste and its leachate in the gabbage carriers during the transport. Besides, as the Project involves considerable waste transport over a long distance, any traffic accident during the transport may result in odor from the leaked waste that will affect the local environmental sanitation. As a result, it is advisable that the Project owner pays more attention to the waste transport process, improves the tightness of waste carriers, checks and maintain the carriers, forcefully drops out any leaking vehicle and protects the urban sanitation environment.

6.7.2.3 Wastewater impact As it is possible to prevent the waste leachate from leaking from the waste carriers during the transport process when the vehicles provide good waste tightness, there will be little impact on the quality of the water bodies along the road where the waste carriers pass. However, any leakage of the waste water from the carriers may cause pollution to the nearby water bodies when the rainwater washes over the ground.

6.7.2.4 Measures against environmental pollution along the waste transport route To mitigate the impact on the road from waste transport, we recommend that the following measures be taken: Carry the waste in enclosed waste carriers incorporating waste leaching liquid tanks, reinforce maintenance of the vehicles in service, keep renewing the waste carriers and make sure that the carriers provide sound waste tightness. Clean the waste carriers on regular basis and keep clean the roads and the roadsides. Minimize the time of stay of the waste carrier at any sensitive point, and try to avoid any new offices or residential point or other sensitive points on either side of the plant access. ④ Furnish each waste carrier with all necessary communication tools for emergency communication. The driver should notify the relevant management department any accident during the transport to enable proper treatment. Reinforce ideology education and technical training of the drivers and avoid any traffic accident. ○6 Avoid any noise to disturb the people in the nighttime. Inject information management means into waste carriers; reinforce tracking and supervision of waste carriers; build an information management database of waste carriers and enable metering management and information feedback of waste transport. Implement effective dispatch of carriers entering the waste treatment terminals and reduce vehicle lags.

6.8 Relocation progress and schedule

The Project includes 3 sensitive points of Fangquan Group of Dianshang Village, Qianjiawan and Dianshang Kindergarten within 300m of the plant boundary. There used to be 109 households of residents in Qianjiawan. So far, relocation has been completed in Dianshang Kindergarten and Qianjiawan. In Fangquan Group of Dianshang Village, there used to be 66 households and now only 5 remain unmoved and are under negotiation of relocation. As promised by Zhenjiang New District Administration Committee, relocation of Fangquan Group of Dianshang Village will be complete within 3 months after the Project is officially approved. The underway relocation work by Zhenjiang New District Administration Committee takes into account both the 300m atmospheric environmental protection distance and the space distance from the International Chemical Industrial Park to the residential point on the north side of the Project. That’s why Zhongdian Group of Dianshang Village, Shangdian Group of Dianshang Village, Xiadian Group of Dianshang Village, Xiaoxinzhu, Xinzhu Village and Beixie which are 300m outside the 300m limit from the plant boundary are included into the relocation program. As promised by Zhenjiang New District Administration Committee, relocation there will be complete by the end of 2010. As planned, the Project will be put into production at the end of 2010. Before the Project is complete, relocation of Fangquan Group of Dianshang Village, Zhongdian Group of Dianshang Village, Shangdian Group of Dianshang Village, Xiadian Group of Dianshang Village, Xiaoxinzhu, Xinzhu Village and Beixie will all be complete. The relocated residents will be resettled in Dagang Street.

7 Environmental Risk Analysis

7.1 Purpose and key of environmental risk assessment

Purpose of environmental risk assessment The purpose of environmental risk assessment is to analyze and predict the impact on personal safety and environmental impact degrees from any potential risks, hazardous factors in the proposed Project, possible outburst events or accidents in the construction and operation of the proposed Project (excluding any intentional destruction or natural disaster in general) that may lead to leakage of any toxic, hazardous, flammable or explosive substance, and to provide reasonably workable prevention, emergency and mitigation measures so that the proposed Project is kept within an acceptable level of accident rate, loss and environmental impact. Key of environmental risk assessment Environmental risk assessment should include prediction and prevention of harm to the public outside the plant (station) boundary, deterioration of the environmental quality and impact on the eco system from any accident as the key of the assessment work. The concern point of environmental risk assessment should be the impact of any accident on the environment outside the plant (station) boundary.

7.2 Determination of assessment grade and assessment scope

7.2.1 Assessment grade Standard for assessment grade According to the Technical Guidelines for Environmental Risk Assessment on Projects (HJ/T169-2004), the standard for classification of environmental risk assessment grade is detailed in table 7.2-1 below. Standard for classification of environmental risk assessment work grade Flammable, Virulent risk General toxic Explosive risk Type combustible material risk material material risk material Significant risk I II I I source Non-significant risk II II II II source Environmental I I I I sensitive area Division of assessment grade Determination of material risk Identification of main material risks involved in the proposed Project is detailed in the table below.

Table 7.2-2 Risk identification of main chemicals in proposed Project Substances Toxicity; flammability & combustiveness; explosiveness No.1 in Table 1, Standard for Identification of Toxic Substances, Appendix A to Technical Guidelines for Environmental Risk Assessment on Projects HCl (HJ/T169-2004), general toxic substance, not listed on Catalog of Virulent Chemicals (2002); class 8.1 in Catalog of Hazardous Chemicals (2002), acid corrosive substance, hazardous cargo No. 81013.

Not toxic substance listed in Catalog of Virulent Chemicals (2002). No.3 in Table 1 Standard for Identification of Toxic Substances, Appendix A to Technical Guidelines for Environmental Risk Assessment on Projects NH3 (HJ/T169-2004), general toxic; becoming explosive mixture when mixed with air, flammable and explosive when exposed to open flame or high heat. Becoming explosive mixture when mixed with air, flammable and explosive H2S when exposed to open flame or high heat. LC50: 444pm (absorbed by big mouse). Not toxic substance listed on Catalog of Virulent Chemicals (2002). Diesel oil is a mixture of C16~C23 hydrocarbons with boiling range of 200~380 ℃ . Its volatility is much lower than gasoline, density Light diesel (20℃)0.80~0.85; flash point 45~55℃; fire risk IIB, No.3 in Table 1 Identification of Flammable Substances, Appendix A to Technical Guidelines for Environmental Risk Assessment on Projects.

From the table above, light diesel is a flammable liquid, HCl, CO, NH3 and H2S are general toxic risk substances and CO, NH3 and H2S are flammable gases.

Identification of significant risk sources Materials involved in storage and transport of the Project include light diesel, which is a flammable and explosive product. As it features high steam pressure, easy volatilization, low flash point and very broad explosion limit, it is prone to combustion and explosion in normal environment. Any negligent design or improper management in the transport, storage or handling may cause leakage, explosion or combustion from accidents, which will result in serious harm, severe environmental pollution, tremendous economic losses and personal casualty. In the Project, a 20m3 oil tank is buried in the ground at the oil depot with volumetric loading factor of 0.85 and max storage capacity of 17t. Taking light diesel, HCl, CO, NH3 and H2S as the identification factors, and with reference to table 2 and table 3 of Appendix A to Technical Guidelines for Environmental Risk Assessment on Projects (HJ/T169-2004) and Identification of Significant Risk Sources (GB 18218-2000), we have identified the significant risk sources as shown in table 7.2-3 below, from which we can see there is no significant risk source in the Project.

7.3 Risk identification

7.3.1 Identification of material risk According to Appendix A (normative appendix) to Technical Guidelines for Environmental Risk Assessment on Projects (HJ/169-2004), toxic, flammable and explosive substances involved in the Project include light diesel, HCl, CO, NH3 and H2S. Any leakage of diesel in the diesel tank, when exposed to open flame, may also cause fire or even explosion. Any leakage of HCl, CO, NH3 or H2S will cause certain impact on the ambient environment.

7.3.2Risk analysis of main production process According to our engineering analysis, environmental risks in the production of the proposed Project mainly assume the following three cases: one is failure to the fumes treatment plant associated with the incinerator; one is concurrent failure to all the 3 incinerators due to unexpected accident; the other is the impact on the ambient environment from explosion due to excessive CO inside in the incinerator.

7.4 Source analysis

7.4.1 Analysis of accident sources According to our analysis, the Project mainly involves the following accident sources: Failure to the fumes treatment plant associated with the incinerator We have designed spares for all the critical parts of the fumes treatment plant in the waste incineration plant such as the rotary atomizer, active carbon ejector system and bag deduster. From our calculation and the practical operation effect of the similar Projects, there is very little possibility that the fumes treatment fails the requirement due to equipment failure and the frequency is twice a year max. Under normal conditions, the bag dedusters can be replaced in batches in the offload overhaul according to the service time. Any leakage of the bag deduster will be immediately discovered by the online monitor. The bag dedusters used in the Project have a number of independent cubicles so that cubile where the bag is leaking will be immediately isolated and replaced and dust treatment will remain effective. The dust suppression efficiency of the bag deduster in the Project can be as high as 99.8% under normal conditions. The dioxin adsorbed to the fly ash will be totally removed. According to statistics of our monitoring, under any leakage in the bag deduster, the max concentration of soot emission will increase to around 3 times of normal emission. So the dust suppression efficiency will still be 99.4%. According to studies of relevant references, when active carbon is put into the bag deduster, the total concentration of dioxin in the fly ash from recineration will increase to 460ng/g from the original 254ng/g before the active carbon is put in. This is mainly because the active carbon is collected by the bag deduster into the fly ash after it adsorbs the dioxin, which increases the dioxin content in the fly ash, thus reducing the concentration of the dioxin in the emitted tail gas from incineration. From the research result, even when no active carbon is ejected, the dioxin adsorbed to the fly ash equals to 55% (254/460=0.55) of the dioxin adsorbed to the fly ash when there is active carbon. So, under any failure to the active carbon, there is still certain treatment effect to the dioxin adsorbed to the particles. The waste recineration treatment system of Xinmin Thermal Power Co., Ltd is similar to the Project. It is a semidry + active carbon ejection + bag deduster. The purified tail gases of the sytem were tested by Chinese Adamedy of Sciences Aqutic Life Dioxin Test Lab and the result is: the dioxin in the ash is 0.00482TEQng／m3 (all the fllue gas volumes are the ones under standard state) and the dioxin in the gas phase is 0.00023TEQng／m3. At this rate, when active carbon is ejected, the proportion of dioxin adsorbed in the fly ash is around 95%. Even if no active carbon is ejected, some of the dioxin is still adsorbed to the fly ash, and the dioxin volume is calculated at 55% of the volumn when active carbon is ejected (result of the foregoing study). So under any failure to the active carbon ejection, the dioxin adsorbed to the fly ash by bag dedustering alone will be 52% of the total dioxin volume (95％*55％=52%). Under any concurrent failure to the bag deduster and active carbon ejection, the treatment efficiency of dioxin is 51.7% (52%*99.4％=51.7%). As conservatively predicted, when multiplied by the coefficient of 87%, the treatment efficiency of dioxin can be as high as 45%. Our assessment has included the most negative conditions when both the active carbon and the bag dedusters of the fumes purification plant fail, there will be the max emission of dioxin. This, less the 45% efficiency, the emission concentration is 2.75ngTEQ/m3 and the emission volume is 0.503mgTEQ/h. Under any failure to the semidry neutralization tower, considering accidental emission of HCl for 2~3 hours, at the removal rate of 50%, the emission volume of HCl is 54.9kg/h. From all the above, the max credible accident source intensity under any failure to the fumes treatment plant of the Project is detailed in table 7.4-1 below. Table 7.4-1 Emission parameters of accident pollution sources Chimney Chimney Outlet Fumes Emission Type of outlet height diameter volume Pollutant velocity Duration accident temperature (m) (m) (Nm3/h) (kg/h) (℃) Concurrent failure to active carbon 80 1.6⑸3 144 183000 Dioxin 0.503mgTEQ/h 1h ejector & bag deduster Failure to semidry 80 1.6⑸3 144 183000 HCl 54.9 2h neutralization tower Impact on the ambient environment from fire explosion risks due to leakage of the diesel oil tank Any damage to the oil tank, pipeline or valve of the fuel combustion system will result in fuel oil leakage and, when exposed to open flame, may cause fire or even explosion. For this, the proposed Project plans to take corresponding preventive measures like installing cofferdam around the oil tank, enacting fire protection rules, forbidding any smoke or fire inside the workshop, installing fire suppression devices like fire extinguishers in the workshop, which will be preventive against such risks. However, as any such accident will cause serious concequencies, we have to keep alert and further reinfrce fire protection measures. Impact on the ambient environment from accidental emission of wastewater The waste leachate and flushing wastewater from the Project will be pretreated inside the plant to the connection standard and then directed to Dagang Sewage Treatment Plant together with the domestic sewage for centralized treatment. Under any failure to the plant sewage treatment station, the 1200m3 regulating pond will be used as an accident pond. The leachate will be temporarily stored in the regulating pond and retreated and discharged after the plant sewage treatment station come back to normal service before eventually discharged into Dagang Sewage Treatment Plant for further treatment after coming to the required standard. Impact on the ambient environment from explosion due to excessive CO in the incinerator Concentration of CO produced in the incinerator under normal conditions is 100mg/m3 with volume ratio of 8.0⑸10-5, which is far lower than the explosion limit of CO (v%) 12.5-74.2, and is not exposed to explosion under normal conditions. There is also little probability of, and no report about, any explosion due to excessive CO content. The main reason for excessive CO is: incomplete combustion due to insufficient air of the FD fan (primary and secondary fans) resulting in excessive CO. At the same time, the ID fan is not exhausting noticeably more air so that a large amount of CO gathers in the furnace and the waste-heat boiler. For the Project, the probability of such event is relatively small and if any, it won’t last long, the max being 1 hour. At this time, the concentration of CO produced is 250mg/m3 with volume ratio of about 1.97⑸10-6, which is far lower than the explosion limit of CO (v%) 12.5-74.2, implying very little probability of explosion. If any, pollutants in the waste gas like HCl will leak into the ambient environment and increase the impact on the ambient environment. Analysis of the impact of methanol explosion accident on the ambient environment While there is possibility of methanol explosion in the waste pit during the storage when all the 3 incinerators are out of service, the chance is very remote. In fact, there is larger possibility of methanol explosion in the waste leachate collection room. Wherever this happens, there are two prerequisites for any methanol explosion to happen: the methanol is within the explosion concentration, and there is fire source in the methanol gas that is within the explosion concentration. For the Project, the probability of such event is relatively small and can absolutely be avoided by taking preventive measures. Impact of accidental emission of odor pollutants on the ambient environment due to the failure of the odor pollutant control measures to work normally There are three reasons why the odor pollution control measures fail normal service and cause accidental emission of odor pollutants: The incinerator shuts down and the primary fan stops exhausting air from the waste pit; The air curtain device stops work due to failure; There is large disrepair in the waste pit plant and the waste pit is no long airtight. Item (1) above is the most impactive with the probability of once a year or every two years max and duration of 2~4 days. The 3 incinerators of the Project will not be overhauled simultaneously. However, under any accident when all the 3 incinerators are out of service, odor will mainly come from the waste pit, which will not be burned in the incinerator. We plan to install an active carbon deodorizing device on the side wall of the waste pit and exhaust the odor gases in the waste pit with the fan into the active carbon deodorizing device to remove the odor and then direct it into the 89m-high chimney for overhead emission. When overhauling the incinerator, we have designed to remove the odor with active carbon deodorizing devices. Active carbon adsorbs and purifies cacosmia much more effectively than any other purification method and the deodorizing rate of active carbon can be as high as 80%. Besides, it can purify a number of odor-producing substances simultaneously and is also suitable for non-permanent continuous service. Emission of odor pollutants from the Project is detailed in table 7.4-2 below. From the table, the emission of

NH3 and H2S now conforms to Emission Standard for Odor Pollutants (GB14554-93). Table 7.4-2 Cacosmia gas production under the accident Waste gas Control measures Pollutant Inner Pollutant Height Source amount & removal emission diameter production (kg/h) (m) (Nm3/h) efficiency (kg/h) (m) NH ： Active carbon 3 Waste NH ：0.601 0.12 30000 3 adsorption 80 1.6 pit H S：0.0086 H S： 2 80％ 2 0.0017

7.4.2 Max credible accident As designed, the max cubage of the light diesel tank is 20m3. As there is an accident cofferdam around the tank, all the diesel oil will be kept within the cofferdam under any accident from coming into the surface water environment. There is very little possibility that under startup or shutdown of the incinerator, the production is not properly controlled, the furnace temperature is too low, there is too much CO in the fumes and concurrently both the active carbon adsorption device and the bag deduster for fumes purification are out of normal service. Comparatively, it will cause more serious impact on the environment when the fumes treatment plant associated with the incinerator fails the normal treatment efficiency, which will result in superstandard emission of the flue gases into the atmosphere and pollution to the surrounding air. This is why we have identified the failure of the fumes treatment plant associated with the incinerator to achieve the normal treatment efficiency as the max credible accident of the Project. According to the data and our analogy analysis, the probability of such accident is 1⑸10-5/a. 7.5 Analysis of accident consequences

7.5.1 Risk prediction and calculation of atmospheric environmental accident The max credible accident source intensity under any failure to the fumes treatment plant of the incinerator is detailed in table 7.4-1 below. Prediction mode In predicting the consequence of accidental emission of flue gases, we used abnormal emission model to calculate the resulted downstream pollutant concentration distribution and superstandard distance.

Assessment standard According to Circular on Further Reinforcing the Environmental Impact Assessment Management of Biomass Power Generation Project (HF [2008] 82), dioxin accident risks are assessed at the daily withstandable intake of 4pgTEQ/kg for human body and the permissible intake into the human body through respiration is rated at the daily withstandable intake of 10%. At the average weight of 60kg for healthy adults, the permissible hourly intake into the body through respiration per person is 1pgTEQ/person hour. Statistics shows that the ventilation of average people in one minute when quiet is 0.0042m3 and the hourly ventilation is 0.252 m3. As calculated, the permissible concentration of dioxin into the body through respiration is 3.97 pgTEQ/m3. HCl will be subject to the primary concentration standard of 0.05mg/m3 specified in Sanitary Standard for the Design of Industrial Enterprise (TJ36-79). Prediction result We use the model above to calculate the max average hourly concentration of the pollutants under accident emission and the superstandard scope as shown in table 7.5-1 below.

When the accident ends, as the pollution sources have stopped emitting pollutants, the pollutant concentration will gradually come to the normal level (about 1h). Therefore, the max credible environmental accident risk of the Project is acceptable. However, the impact on the environment is noticeable greater than normal emission. Therefore, preventive measures should be taken to avoid any accidental emission. Under any failure to the fumes treatment plant, the impact on the downwind environmental protection targets is detailed in table 7.5-2 below.

When the accident happens, the HCl and dioxin will cause certain impact on the sensitive points, but the impact is still within the assessment standard limit. When the accident ends, as the pollution sources have stopped emitting pollutants, the pollutant concentration will gradually come to the normal level. It is advisable that the Project owner reinforces management to avoid any such accident and actuates the emergency program once any such accident happens to the impact.

7.5.2 Impact on the ambient environment from accidental emission of cacosmia when cacosmia pollutant control measures are out of normal service When the accident happens, use the accident fan to extract the gases (cacosmia) in the waste pit into the upper air through the chimney to turn the non-organized emission to organized emission and mitigate the impact on the ambient environment. Besides, the proposed Project will minimize the production of cacosmia gases by spraying deodorizing agent into the waste pit. Under any accident, the impact of the collected cacosmia gases on the ambient environment after adsorbed by active carbon is detailed in table 7.5—3 below. Max average hourly concentration of cacosmia gases under the accident Prediction Stability B C D E Remarks factor Max downwind 0.0008 0.0008 0.0007 0.00055 concentration (mg/m3) Percentage of ground Windy level pollutant 0.4 0.4 0.4 0.3 concentration (%) Superstandard scope (m) / / / / NH 3 Max downwind 0.0015 0.0014 0.0011 0.00015 concentration (mg/m3) Percentage of ground Zero-speed level pollutant 0.8 0.7 0.6 0.1 light wind concentration (%) Superstandard scope (m) / / / / Max downwind 0.00001 0.00001 0.00001 0.00001 concentration (mg/m3) Percentage of ground H S Windy 2 level pollutant 0.1 0.1 0.1 0.1 concentration (%) Superstandard scope (m) / / / / Max downwind 0.00002 0.00002 0.00002 0.000002 concentration (mg/m3) Percentage of ground Zero-speed level pollutant 0.2 0.2 0.2 0.02 light wind concentration (%) Superstandard scope (m) / / / / Under any accident, when the cacosmia gases are collected and adsorbed by active carbon, the contribution of the pollutants to the max average hourly concentrations of NH3 and H2S will account for 0.8% and 0.2% respectively of the assessment standard limit. From this, under any accident, the cacosmia gas pollutants will not cause much impact on the ambient environment after adsorbed by active carbon as the total emission is rather small, and the environmental risk is acceptable. ◆ When the active carbon adsorption device also fails Assuming that when all the 3 incinerators are out of service, the active carbon adsorption device for the accident treatment also fails, resulting in direct emission of NH3 and H2S into the atmosphere without any treatment, the impact on the ambient environment is shown in table 7.5-4 below.

Therefore, the Project owner should reinforce every management and maintenance of the active carbon adsorption device associated with the waste pit and make sure that the active carbon adsorption device provides normal service under any accident; reinforce management of the operation and repair of the incinerators and avoid any concurrent failure to all the 3 incinerators; once this occurs, actuate the accident fans and active carbon adsorption device immediately to minimize the impact.

7.6 Preventive measures against accident risks 7.6.1 Countermeasures against pollution emission accident from waste gas treatment system

The specialist is responsible for everyday environmental management to formulate the Duties of Environmental Management Personnel and Preventive Measures against Environmental Pollution, and to strengthen the supervision and management of the waste gas control facilities of the incinerators. Carry out regular inspection and maintenance of the waste gas treatment facilities and equipment and solve any accident hazard upon discovery. Install an online fumes monitor to enable online monitoring of the waste gas control effect. ○4 Introduce waste gas control equipment and facilities with an advanced technology and good effect to make sure that the pollutants are emitted to the specified standard. ○5 When starting the incinerator, first preheat the bag deduster with electricity and, when it comes up to the required temperature, start the incinerator and bag deduster simultaneously. Use light diesel to assist combustion when the incinerator temperature is low and keep the incinerator850℃.

7.6.2 Countermeasures against diesel leakage and explosion risks Strictly follow the national rules on production safety, take technical measures of class II production and storage safety and abide by the fire protection rules and codes for class II industrial design. Establish and complete production safety responsibility system, carry out regular safety inspection, inspect all the pipes and valves of the oil storage tank regularly, find out any accident hazard and immediately remove them. Enhance staff’s safety awareness and education, strictly carry through the safety rules and systems, prevent any maloperation and enact corresponding emergency measures. ④Keep the diesel oil tank a certain distance from the incinerator and avoid placing them too close to each other. Keep off any smoke or fire source nearby the diesel oil tank, put up signs of hazard in noticeable places and furnish proper fire suppression apparatuses.

7.6.3 Preventive measures against environmental risks from oil depot Build a cofferdam and collection sump around the oil tank up to relevant standards. (1) The oil tank should be build in strict accordance with fire protection codes so that it conforms to the required standard in terms of the fire protection distance, fire exit and fire suppression facilities; once there is fire on the storage tank, the heat radiation from the flames should be far enough from any adjacent tank, and the fire suppression facilities (cooling by spraying water) should comply with the required size of equipment. A fire bank should be built around the storage tank with the required effective cubage and height of the fire bank. It is advisable that the Project enacts complete blocking and preventive measures for the purpose of risk control. In addition to designing the cofferdam or fire bank, a leaked finished oil collection sump should also be considered inside the cofferdam, as well as an emergency sump to receive the fire protection fluid of the entire plant for fire accidents. Cut off the rainwater valve in the tank area first upon any leakage of light diesel and keep any leak away from the rainwater system; try best to cut off the leak source. Turn off the rainwater drain valve first upon any fire or explosion and block any rainwater reception inlet that might be polluted; make sure that all the fire suppression wastewater is directed into the fire water collection sump; besides, spray fire water to wash off any carbon monoxide or soot from the fire to mitigate the impact on the environment and make sure that all the firewater is directed into the emergency sump. 7.6.4 Preventive measures against sewage accident To keep Dagang Sewage Treatment Plant under stable service, when the leachate treatment system inside ht plant is out of normal service, first store the percolated waste fluid produced in the regulating pond to avoid impact load on Dagang Sewage Treatment Plant. The Project should employ much effort on monitoring accident symptoms, carry out regular inspection tours, regulation, maintenance and repair to find out any symptom of abnormal service that might cause accidents. Operators should receive strict training on both theory and practical operation before taking their respective jobs.

7.6.5 Preventive measures against explosion accident of incinerator due to excessive CO To avoid explosion accidents due to excessive CO in the incinerator, we may take the following prevention, mitigation and emergency measures: Find out an incomplete burning by monitoring the oxygen volume in the incinerator and make adjustment from time to time so that the waste is fully burned; Interlock the ID fan and FD fan so that the FD fan will shut down and the incinerator will be stopped too once the ID fan is out of service; Keep watch of the negative pressure in the furnace and avoid any positive pressure; Stop supplying air immediately and turn up the ID fan to exhaust the air for a time where the incinerator shuts down for any explosion inside the incinerator; Ensure proper everyday inspection and maintenance of the incinerator and avoid any accident.

7.6.6 Preventive measures against methane explosion Install a concentration monitor in the waste pit and leachate room to monitor the methanol concentration and actuate the exhaust fan to bring down the methanol concentration when it comes to a certain limit; Strictly follow the operation rules for waste pit and leachate room, and in particular avoid any fire sources in the waste pit when all the 3 incinerators are out of service. Where operation producing sparks or flames like welding is unavoidable in the waste pit or leachate room, turn on the accident exhaust fan first to bring down the methanol concentration to a certain limit; Especially in the leachate room, a separate drafting system and draughting system should be installed to bring down the methanol concentration by supplying and exhausting air and avoid③ explosion.

7.6.7 Preventive measures against accidental cacosmia emission under the abnormal operation

In order to prevent accidental emission of cacosmia pollutants, we may take the following prevention, mitigation and emergency measures: Reinforce everyday inspection and maintenance of the incinerators and minimize the possibility of accidents; Mitigation measures: Install accident deodorizing devices. Under any failure to the odor measures, overhaul or when all the 3 incinerators are out of service, to avoid odor leakage and maintain negative pressure in the waste pit, we should initiate the accident deodorizing fan to extract the odor in the waste pit so that the odor will be emitted through a 20m-high chimney after adsorbed by active carbon.

7.7 Enactment of emergency accident program

7.7.1Purpose for enacting emergency program for risk accidents The purpose of enacting emergency programs for risk accidents is to enable the maximal effect of rescue at the highest speed in the event of any accident, control the expansion within the shortest time possible, mitigate harms from the accident and minimize losses from the accident. 7.7.2 Basic requirements of emergency program for risk accidents An emergency program for risk accidents should be scientific, practical and authoritative. As emergency rescue of risk accidents is of high scientific requirement, scientific analysis and demonstration are necessary in enacting any emergency program to ensure a stringent, uniform and complete emergency program; an emergency program should come in line with the objective conditions of the Project and be practical, simple and easy for understanding and implementation; it should specify the duty, authority, task, work criteria, reward and punishment in the accident disposal so that they will constitute a system of the company and guarantee its authority. 7.7.3 Establishment and duty of emergency environmental risk organization For potential environmental risks, the proposed Project should establish an emergency rescue leadership group under accident state (advisable to be undertaken by the HSE management group). The emergency leadership group is a standing body of the company for preventing and disposing outburst accidents mainly performing the following functions: Compile and revise emergency accident rescue programs. (2) Set up an emergency rescue team for training and drills. Check the implementation of individual safety work. Examine and ensure the effectiveness of preventive measures against significant accidents and preparation work for emergency rescue. Issue and release all the orders in emergency rescue actions.

7.8 Summary

Toxic, flammable and explosive substances involved in the Project include light diesel,

HCl, CO, NH3 and H2S. Environmental risks in the production of the proposed Project mainly assume the following three cases: one is failure to the fumes treatment plant associated with the incinerator; one is concurrent failure to all the 3 incinerators due to unexpected accident; the other is the impact on the ambient environment from explosion due to excessive CO inside in the incinerator. The light diesel tank will be furnished with accident cofferdam around it to keep all the diesel oil within the cofferdam under any accident from coming into the surface water environment. Our prediction of failure accidents of the fumes treatment facility shows that while under accident emission, dioxin pollutants are more impactive on the ambient environment than normal conditions, the emission is still within the relevant assessment standard and is lower than the daily withstandable intake of 4pgTEQ/kg for the human body, and the permissible intake into the body through respiration rated at the withstandable daily intake of 10%; under accident emission, cacosmia gases are emitted through an 80m-high chimney after treated by active carbon. As the total emission is small, it is not so impactive on the ambient environment. However, it is important that the Project put more effort on the management, put into effect all the accident risk preventive measures provided herein, establish emergency accident programs to minimize generation and expansion of accidents and keep the local environment safe from pollution. In a word, the risk level of the Project when complete is acceptable provided all the environmental risk preventive measures are put into effect.

8 Demonstration of Pollution Control Measures and Technical Economic

Feasibility

8.1 Wastewater control measures

Split flow system of fresh water and wastewater is applied for the internal drainage system of the Project. Wastewater generated by the proposed Project mainly includes waste leachate, cleaning wastewater and sewage etc. After being collected and treated up to standard in the self-contained leachate treatment station, waste leachate and cleaning wastewater are connected to Dagang Sewage Treatment Plant for centralized treatment together with sewage.

8.1.1 Internal pretreatment measures Process flow of waste leachate treatment Waste leaching water is discharged to Dagang Sewage Treatment Plant after being pretreated up to specified standard. UASB + MBR + nanofiltration treatment process is applied in leachate treatment station. The process flow is shown in figure 8.1-1.

Process flow of waste leachate treatment Description of process flow: The wastwater treatment system is composed of five parts, including Regulating tank; UASB reaction tank; Membrane bio-chemical reactor MBR system; ④ Nanofiltration NF system; Sludge treatment system. Leachate in the waste pit flows into the leachate collection tank in the main workshop, rinsing water of the unloading lobby and waste passage are also discharged into the collection tank, then they are pumped into the grille of wastewater treatment station and flowing into the sedimentation tank, then to the leachate regulating pond, over pipes are set in the grille bay, leachate also can enter the sedimentation tank through the bypass grille sludge remover so as to ensure reliable operation of leachate conveying system. Capacity of the regulating pond is 4d and its effective volume is V1＝300⑸4≈1200m3. Wastewater in the regulating pond is lifted by pump and then enters into the bottom of UASB reactor through the water distributor, it flows from bottom to top at certain velocity, sufficiently contacts with anaerobic sludge when passing through the suspended sludge blanket and granular sludge blanket, organic matters are absorbed and decomposed; generated methane is emitted from the collection chamber of the upper three-phase separator of UASB, wastewater carrying suspended sludge enters the sedimentation area of the three-phase separator, sludge of good sedimentation behavior returns to the main body of reactor through the sedimentation face, wastewater carrying little light sludge is discharged from the upper reactor. The anaerobic reactor can granulate the sludge in it, which is of good sedimentation behavior and extremely high methane-producing activity. It makes higher concentration of sludge and longer sludge age in reactor, greatly improves COD volume load, and realizes favorable contact between sludge and water. Due to the application of high COD load, the output of biogas is high, then the sludge is under expansion and fluidized state, so that the efficiency of mass transfer is enhanced and sufficient sludge-water contact is realized. The sludge bed mainly contains micro-granular sludge and flocculent sludge, it has two sets of UASB, and the volume of reaction area of each UASB is 750 m3. If the height of reaction area is 7.5m, the area of a single pond is 750/7.5＝100 m2. The effluent from anaerobic reactor enters the MBR system for further treatment. MBR reactor includes pre-denitrification tank, nitrification tank, post- denitrification tank and UF system. In the nitrification tank, a specially-designed internal circulation jet aeration system of high efficiency is applied, so the utilization rate of oxygen can be up to 25%; through aerobe action of high activity, most organic substances can be degraded, ammonia nitrogen and organic nitrogen can be oxidized as nitrate and nitrite to the denitrification tank, and then deoxidized as nitrogen gas in oxygen deficient environment, so as to realize denitrogenation. MBR reactor isolates purified water from thallus through ultrafiltration membrane, return-sludge flow can make the concentration of sludge in the bio-chemical reactor be up to 15g/L, and part of organic substances difficult to be biodegraded in the leachate also can be degraded gradually by micro-flora formed through endless acclimation. BOD/COD=0.5 leachate in the waste pit is of good biochemical feasibility, COD design removal ratio is 96% and that of ammonia nitrogen is 99%. Sludge-water mix treated in the nitrifying reactor enters the post-denitrification tank, which is added with carbon source to reduce total nitrogen further. Effluent of the post-denitrification tank enters the ultra-filtration system through ultra-filtration s water feed pump, 0.05μm tubular type ceramics ultra-filtration membrane and cross flow filtration method are applied for the ultra-filtration treatment process, its internal and external surfaces are tight with micro-pores closed distributed, the porous support layer is in the center. Isolating purified water from thallus through ultra-filtration membrane, ultra-filtrated concentrated solution brings the activated sludge to directly return the nitrifying system by the action of ultra-filtration circulating pump. Retention time of organic substances difficult to be degraded in the biochemical treatment system is relatively prolonged, so microorganisms can be acclimated effectively, part of those difficult to be degraded also can be inverted as biodegradable components. Residual sludge is introduced back to the sludge thickener. MBR effluent ammonia nitrogen index has been up to standard fundamentally, however, part of organic substances difficult to be degraded cannot be removed completely, applying nanofiltration can further separate macromolecular organic substances difficult to be degraded and part of ammonia nitrogen, so that effluent COD can be satisfying for discharge with the help of further advanced treatment of desalinization. Sludge in the wastewater treatment station are biological treatment residual. In order to bring biological adsorption of biological treatment residual into play and perfect its dehydration property, in design, biological treatment residual is discharged into the sludge thickener, supernatant returns to the regulating pond through clear liquid reflux pump after coagulating sedimentation and sludge concentration, the thickened sludge is delivered to the incinerator for disposal after dehydration in the dewatering system. Waste leachate of the proposed Project can be up to the standard of Dagang Sewage Treatment Plant through UASB+MBR+ nanofiltration process pretreatment. Reachability analysis of treatment efficiency of waste leachate Going through the wastewater treatment process shown in figure 8.1-1 below, pretreatment efficiency of each major process unit is shown in table 8.1-1 below.

From here we see that, wastewater can be up to the standard of Dagang Sewage Treatment Plant through UASB-MBR-NF treatment. 8.1.2Feasibility analysis of sewage flow for the Project (1) A Brief to Dagang Sewage Treatment Plant The sewer network of Dagang Sewage Treatment Plant covers Dagang, Zhenjiang New District, its trunks and lift pumps have been completed. Wastewater of the Project is under the control. CAST treatment process is applied for the plant with 20000m3/d design treatment capability, at present, its actual treatment capability has been up to 15000m3/d. Tail water from the plant is discharged into Dagang River, and finally to Changjiang River, the outlet is about 3200m from the river mouth of Changjiang River. Process flow of Dagang Sewage Treatment Plant is shown in figure 8.1-2 below.

(2) Feasibility analysis of sewage flow of the Project At present, total actual amount of sewage flow into Dagang Sewage Treatment Plant is about 10040m3/d, residue treatment capability is 9960m3/d. Wastewater discharge of the Project is 300m3/d taking up 3.0％of the residue treatment capability; it takes up a smaller percentage and is within the residue treatment capability of Dagang Sewage Treatment Plant. The proposed Project is located within the service scope of Dagang Sewage Treatment Plant; wastewater pipe network is under construction, which will be completed before July 20, 2010. The Project will be put into operation in February 2011 as estimated; as analysis from connection time, connecting wastewater of the Project to Dagang Sewage Treatment Plant is feasible. CAST treatment process is applied in Dagang Sewage Treatment Plant. This process is feasible, considerably capable of resisting impact load, also better for phosphorus removal and denitrogenation. Wastewater of the Project can be up to the connection standard of Dagang Sewage Treatment Plant after internal treatment. To sum up, Dagang Sewage Treatment Plant applies CAST process, which is of effective capability in organic substance degradation, phosphorus removal and denitrogenation. Wastewater of the Project is about 300m3/d taking up 3.0% of the residue treatment capability of Dagang Sewage Treatment Plant, so it will not cause overload running; wastewater quality of the Project is relatively simple, so it may not influence the operation of Dagang Sewage Treatment Plant. So the plan for wastewater connection of the Project by Dagang Sewage Treatment Plant is feasible.

8.2 Waste gas control measures

8.2.1 Control measures of incinerator waste gas Waste incineration means that, in 800~1000℃incinerator, use intensive chemical reaction of combustible constituent in waste and oxygen in the air to give out heat, and convert it into high-temperature combustion gas and solid residue with high temperature. Besides carbon dioxide and water vapor, combustion gas also contains many pollutants, which must be properly treated to avoid secondary pollution; although tail gas treatment equipment applying for the incineration system is same with ordinary air pollution prevention facility, tail gas and pollutants generated from waste incineration have special features, so special system shall be applied for treatment to ensure their emission up to standard. Control of Dioxins generation and emission Respectable plastics, rubbers and synthetic fiber polymers in domestic urban waste contain chlorinated substances in general, so it is the precondition for generating Dioxins. Therefore, in incineration of domestic waste, if the selected process technology is improper or operation is incorrect, it may cause pollution of the air, water source and soil. Semi-dry gas washing tower + bag deduster are applied for pollution control of the Project to reduce Dioxins through reducing it in incinerator and avoiding external low-temperature re-synthesis. Firstly, keep sufficient temperature and gas retention time in the combustion chamber of incinerator, ensure proper oxygen content in waste gas to break down Dioxins in waste; secondly, avoid external re-synthesis of Dioxins, actively promote waste classification at the same time to reduce substances of high chlorine content (such as PVC material) in waste. Dioxin is a kind of compound of high boiling point and low vapor pressure, therefore, when the temperature of fume is lower, Dioxins gas is easy to be converted into fine granules, in this way, bag deduster can be more effective in removing Dioxins under lower gas phase temperature. Examples of Dioxin data changes measured in commercial incinerator plant (fully continuous combustion system) by Mitsubishi Heavy Industries /Martin Association are shown in table 8.2-1 below. Analysis of Dioxins and temperature changes (O2=12%) Fume temperature 200℃ 150℃ Location of Inlet Outlet Inlet Outlet Inlet Outlet Inlet Outlet measurement point (TEQng/m3) 14.5 0.23 29.4 0.29 3.00 0.01 2.30 0.01 Total equivalent

Keeping combustion conditions in the incinerator, Dioxins concentration at the outlet of bag deduster reduces further after fume temperature drops from 200℃to 150℃, at 200℃ operation temperature, concentration at the outlet is 0.23~0.29 TEQng/m3, while it is 0.01 TEQng/m3 at 150℃, which is greatly reduced as compared with the former. Table 8.2-2 shows us Dioxins data examples measured in urban waste incinerator plant (fully continuous combustion system) equipped with dry fume treatment system, fume temperature in which is controlled at 200℃. Comparison of concentration changes at Dioxins inlet and outlet of the incinerator plant (O2=12%) Fume temperature Plant A Plant B Plant C Location of Inlet Outlet Inlet Outlet Inlet Outlet measurement point (TEQng/m3) 1.22 0.03 1.55 0.04 0.92 0.03 Total equivalent As shown in Table 8.2-2, Dioxins concentration at the inlet is 0.92~1.55 TEQng/m3, while it is about 0.03~0.04 TEQ ng/m3 at the outlet. The discharge of Dioxins of the Project shall be 0.1TEQng/m3, so its discharge concentration is lower than that specified in national discharge standard. Measures for controlling the generation of Dioxins of the Project mainly include: a. Optimize the design of waste pit and strengthen operation to improve the heat value of waste entering the incinerator, so as to ensure normal and stable combustion of waste in it, detail measures: ――Increase the dimension of waste pit, design its effective volume for 5~7 days storage, so as to ensure that water in waste can be sufficiently separated out; ――Set perfect leachate guide and collection system to ensure smooth discharge in the waste pit; ――Improved heat value of the leachate in the waste pit by scientific management like stacking and conveying the waste in the storage pit. Through the above measures, the heat value of waste entering into the incinerator also can be effectively improved even when water content of waste is higher in summer, so as to ensure sufficient and stable combustion of waste in it. b. In boiler exhaust design, lengthen the dry section of boiler exhaust, strictly control the mechanical load of it, select the most proper type for waste combustion of low heat value, pertinently optimize the design of furnace to enhance heat radiation inside, so as to ensure drying and sufficient combustion of waste, and keep the temperature in furnace above 850℃. c. Steamed air preheater set for the Project can increase the temperature of combustion air; in addition, the furnace and the lower part of the first passage are laid with insulation material, equipped with peculiar fore-and-aft arches and secondary draft for disturbance and combustion supporting to make the burning fume and combustion air be sufficiently mixed, so as to ensure that the retention time of fume exceeds 2s at above 850℃ and a great deal of Dioxins can be decomposed thereof. d. One diesel oil and fuel auxiliary combustion system is set for each boiler, which composed of oil tank, filter, oil pump, nozzle, auto-ignition equipment, flame detection equipment, fire alarm and restart equipment. Incinerator can continuously operate for above 8000h per year, so auxiliary combustion system is shutdown in general. However, auxiliary combustor is put into use automatically in very few cases when the temperature in furnace cannot be up to above 850℃ because of too low heat value of waste. e. Learned from practical experience of foreign incinerator plant, concentration of CO and element carbon has certain relation with that of Dioxins, the concentration of CO and element carbon in fume is one of the important indexes for judging whether the waste is sufficiently burned or not, the lower the concentration, the more sufficient of combustion degree. In the process, the concentration of CO and element carbon can be reduces through adjusting air flow, speed and injection location, so as to reduce the concentration of Dioxins. f. Through good combustion control, temperature of fume in the furnace or the flue before entering the exhaust-heat boiler is not less than 850℃, retention time of fume in the furnace and secondary combustion chamber is not less than 2s, O2 concentration is not less than 6%, the quantity, temperature and injection location of combustion air are controlled in a reasonable way, i.e. “Three-T” control methods. As shown in practical data of foreign waste incinerator plant, under the above conditions, absolute part of connate Dioxins in waste can be decomposed. g. Reduce the time of fume at 300~500℃ in treatment and discharge through type selection of equipment, reasonable arrangement and improving heat transfer coefficient, control fume exhaust temperature of exhaust-heat boiler not exceeding 200℃, and apply bag deduster for dust control in fume in convenience for reducing Dioxins resynthesis. h. A state-of-art, perfect and reliable auto-control system is equipped for the Project in complete set to ensure good operation of combustion and fume purification system. Fume treatment system combined semi-dry neutralizing tower with bag deduster is applied. Dioxins is of high boiling point, it exists as fine granular in fume (at 150~180℃) nearby the bag deduster, when fume passes through the collector, Dioxins is filtered and gradually accumulated on the dust layer, so that Dioxins is removed from fume. In the Project, semi-dry neutralizing tower cools the waste gas, controls the inlet temperature of bag deduster at 150℃, make noxious organic pollutants coagulate on fly ash, so that the bag deduster removes these organics while collecting dust. In addition, active carbon injection device is equipped on the flue of bag deduster, active carbon (less than 100μm) is sent to the reaction tower through compressed air to absorb Dioxins further. According to related data: injecting active carbon can effectively remove Dioxins in fume after incineration, removal efficiency can be above 98%. Through the above measures, Dioxins discharge can be reduced to the maximum and can be discharged up to standard. Control of heavy metal in waste gas Injecting active carbon to absorb heavy metal is applied for the Project. Taking mercury for example, most mercury exists in fume as gas, mainly HgCl2 in oxidized form, and there is also part of elementary gas Hg. Blowing active carbon into the upstream of fume pipe of bag deduster, the removal efficiency can be more than 80% through absorption reaction. Fume purification system Semi-dry neutralizing tower connected in series with bag deduster is applied for fume purification, fume enters the purifier at the tail of boiler as shown in Fig. 8.2-1. This is actually a spray drying system using high-efficient atomizer to spray slaked lime slurry into the dry absorber from bottom to top or reversely. Tail gas and sprayed slurry shall sufficiently contact each other and generate neutralization in the way of cocurrent flow or counter. Remove acid gas in semi-dry neutralizing tower mainly for deacidification and neutralization, remove acid gas in fume such as chlorine hydride, fluorine hydride, sulfur dioxide and sulfur trioxide; inject active carbon to absorb Dioxins and heavy metal, and then enter the bag deduster, absorb the granular pollutants on the filtering layer when waste gas passes through the bag, then remove by vibration, air flow backwash or pulse rinsing; its dust removal efficiency is related with flow, temperature and dust content of waste gas as well as the material of bag, particle size for removal is about 0.05~20μm in general. bag deduster discharges fine dust particles, neutralizer and deacidification reaction products, active carbon particles absorbing Dioxins and heavy metals in fume after collection through filtering, and then the treated fume is up to standard and discharged into the air through a 89m-high chimney, the minimum fume exhaust temperature is 130℃, soot at the outlet of bag deduster can be up to standard for emission.

The effectiveness of semi-dry process can be assured through the following measures: a. Good and even atomization of lime mortar/cooling water as thin fog; b. By the action of inlet passage and guide plate, fume is evenly distributed when flowing through the reaction tower; c. Due to high-speed cyclone at the inlet, reverse operation of fume and injection of cooling water, fume and fog points are high effectively mixed; d. The optimal operation temperature of fume at the reactor outlet depends on the concentration of pollutants and humidity of fume; e. Negative pressure must be kept in fume passage, so fume does not come out even if it is leaking gas.

8.2.2 Assessment on cacosmia control Cacosmia control in waste incinerator plant Cacosmia in the waste incinerator plant mainly comes from waste nearby the storage, unloading lobby, leaching water storage and incinerator. To avoid its outflow, the following control measures are taken for main cacosmia sources including the waste pit and waste unloading lobby. Air exhaust Use the primary fan of incinerator to exhaust air in the waste pit, leaching water storage and waste unloading lobby as combustion-supporting air of the incinerator. Exhausted air is filtered and dusted firstly, and then sent to the furnace through the preheater, finally cacosmia substances are decomposed and removed in combustion. Barrier curtain Air curtains are set at the entrance and exit of waste unloading lobby used as a barrier to prevent cacosmia and dust from leakage. Isolation of unloading lobby and waste pit In order to seal cacosmia and dust in the waste pit area, several unloading gates which can be③ quickly opened or closed are set between the unloading lobby and the waste pit, which are ordinarily closed to cacosmia in the pit. Certain negative pressure is kept above the waste pit. ④Strengthening the operation management of waste pit Standardizing the operation management of waste pit and using grabs for mixing and turning waste continuously not only can make the heat value of inside waste even, but also can avoid anaerobic fermentation of waste, so as to avoid cacosmia. Closed system for residue treatment Use the closed residue conveying system to implement closed operation under negative pressure of the residue storage, send cacosmia to the waste pit by fan as the primary air for combustion. In operation, cacosmia is controlled mainly through strengthening management, such as trying to shutdown frequency of the whole plant, keeping normal operation of the primary exhaust system, applying closed vehicles for transporting waste, closing the unloading gate of waste pit and sealing the waste pit etc. Cacosmia preventive measures in waste transportation Main anti-dripping measures of waste leachate from waste truck are: New waste trucks must be fully closed auto tippers capable of preventing cacosmia spreading, dropping and dripping of leachate. After collection in the area, firstly discharge leachate in wastewater collection tank on waste trucks into centralized wastewater treatment facility through wastewater pipe network in waste transfer station, and then transport away after closing the water drain valve of anti-dripping device. Supervise and check the anti-dripping facility of leachate of waste truck daily, regularly replace rubber strips and replace damaged parts. The environmental department shall strengthen daily supervision and inspection of roads, forbid waste flying, dropping and dripping of leachate from trucks in transportation. Increase cleaners and shifts for waste transportation roads, enhance cleaning capacity, and increase the frequency of rinsing and sprinkling. Cacosmia preventive measures at leachate treatment station Collection system of waste leachate is composed of leachate tank, leachate pump room and channels. Mechanical air supply and exhaust systems are set. Two fans are equipped for air exhaust to waste pit. The structure for waste leachate treatment shall be covered and sealed to discharge cacosmia gas to the negative pressure area of the waste pit. Comprehensively analyzing waste gas treatment measures of the whole plant, comparing actual treatment efficiency of incinerator plant in operation, Dioxins emission can be controlled within 0.1ng (TEQ)/m3 after the Project is completed, other pollutants such as heavy metals, fly ash and acid gas also can be emitted up to standard; taking cacosmia control measures can mitigate its influence on the surrounding. This shows that, waste gas treatment technology applied for the Project can ensure quality of the surrounding ambient air to the maximum through complete and effective treatment technology and measures.

8.3 Noise control measures and its assessment

Noise of the Project mainly originated from pneumatic power equipment such as fan and high-power water pump. The following noise control measures will be taken respectively thereof: (1) Select low-noise control valves and safety valves for exhaust piping of boiler, install exhaust silencer, and conduct vibration reduction for pipes between valves and silencers. (2) Make soundproof box for fan and install exhaust silencer. (3) Install vibration damper such as rubber joint for each kind of pump; and (4) Cushion blocking for foundation of water pump. Construction materials of good soundproofing and sound deadening properties are used for the boiler house. (5) Strengthen management and maintenance of mechanical equipment. (6) Arrange the main shop reasonably, make noise sources relatively centralized, and apply soundproof architecture in control room and operation room. In control room that operation management personnel are gathering, set sound absorbing device at doors and windows (such as sealing doors/windows), install absorbing ceiling to reduce influence of noise on operation personnel and make the work environment be up to the allowable noise standard. (7) Reasonably arrange general drawing and strengthen internal greening to reduce the influence of noise the ambient environment. In addition, take measures such as overload forbidden, regular maintenance of vehicles, avoiding horns in the plant area to reduce traffic noise arising from transportation vehicles. Through the above measures, all boundary noises can be ensured to satisfying Class III for Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008). Ambient noise at boundary of the Project can be up to standard, so noise generated on the site has little influence on sensitive points.

8.4 Control measures and assessment against solid waste pollutants

8.4.1 Control measures and assessment against solid waste pollutants of the Project Many solid wastes may be generated in production including slag, fly ash, wastewater treatment sludge and domestic waste. (1) Slag The slag hole of incinerator is under the boiler exhaust, slag is delivered to slag pit through slag remover. The slag conveyor is equipped with auto humidifying equipment, so that ash coming out may not fly away. Slag can be used for making in-brick fuel, as aggregate for making calcium silicate concrete, and insulation material for road or roofing, and also can be used as cement raw materials. Slag of the Project is sent to Zhenjiang Xinan Building Materials Co., Ltd for comprehensive application Fly ash According to Policy for Control Technology of Dangerous Waste Pollution (HF [2001]No. 199), flay ash arising from incineration of domestic waste must be collected individually, DO NOT mix with other wastes such as domestic waste and incineration residues, as well as other dangerous wastes; DO NOT store for a long period on the site, DO NOT treat in a simple way and DO NOT discharge. Disposal of fly ash Chelating agent and cement stabilization technology are applied for treatment of fly ash, cement is used as solidification material, harmful substances in fly ash can be stabilized after the chelating agent is mixed with cement. Chelating agent stabilization indicates adding different medicines in the fly ash to make heavy metals in it become sulfide, hydroxide, chelate and other complicated stable compounds, so as to reduce emission of heavy metal in fly ash to the environment, which is of good stabilization efficiency of fly ash. At present, DTC chelating agent is more popularly used for heavy metals in the world. Through years of devotion, Tsinghua University has developed two series of DTC chelating agent products. This product is a kind of odorless and noncorrosive clear liquid. In stabilization of cement, dicaicium silicate and tricalcium silicate in cement are changed into CaO⑷SiO2⑷mH2O gel and Ca(OH)2⑷CaO⑷SiO2⑷mH2O gel through hydration reaction, which are gradually solidified as stabilization body of extremely high mechanical strength after enveloping the fly ash. And that, Ca(OH)2 makes materials have higher pH value, so the most part of heavy-metal ion form into insoluble hydroxide or carbonate, which is fixed in the crystal lattice of cement matrix and can effectively prevent heavy metal from leaching out. As shown in related test data, when the mix ratio of cement is 0.33, the solidification efficiency of fly ash is the optimal. Stabilization products can be satisfying standard requirement and buried for disposal through a period of maintenance for completing its hydration process. Analysis of properties of fly ash According to research report of gelling properties of fly ash and slag from incineration of urban domestic waste issued in 2003 by Tongji University, chemical composition of fly ash of Shanghai Pudong Yuqiao Waste Incinerator Plant is shown in table 8.4-1. We can see from the Table that, the content of CaO in fly ash is the highest taking up 29.4%, and then SiO2 taking up 27.2%. Chemical composition of fly ash of Shanghai Pudong Yuqiao Waste Incinerator Plant (Unit：%) - Designation SiO2 Al2O3 Fe2O3 CaO MgO SO3 K2O Na2O Cl Fly ash 27.2 8.63 4.5 29.4 1.76 12.03 3.2 2.44 10.0 In addition, according to the Actuality of Fly ash Treatment of Japanese Waste Incineration complied by Wang Zhaolin (Environmental Science Trends, the 1st periodical,

1995), major constituents of fly ash are SiO2 25.4, Fe2O3 9.44, Al2O3 4.71, Na2O 9.02, K2O 2- - 7.88, MgO 2.78, CaO 7.20, ZnO 3.45, SO 4 10.25, Cl 11.28 and PbO 1.38, water conent is less than 30%, it also contains minute quantities of metal oxide including Ni, Mn, Cu, Cr, Cd and Hg. Fly ash also contains active carbon powder gathering heavy metals, trace Dioxins compounds and other organic compounds; it is reported that the content of Dioxins compounds in fly ash of Canada incinerator is 319.4ng/m3. Guangzhou Environmental Sanitation Institute carried out leaching experiment of heavy metals for fly ash solids of Guangzhou Likeng Domestic Waste Incineration and Generation Plant in 2006, test results are shown in table 8.4-2 below. Table 8.4-2 Leaching concentration of heavy metals for fly ash solids of Guangzhou Likeng Waste Incineration Plant（mg/L) Date Hg Cd Pb Cr6+ 2006-09-01 <0.005 <0.05 <0.05 <0.013 2006-09-02 <0.005 <0.05 <0.05 <0.010 2006-09-03 <0.005 <0.05 <0.05 <0.010 2006-09-04 <0.005 <0.05 <0.05 <0.010 2006-09-05 <0.005 <0.05 <0.05 <0.010 2006-09-06 <0.005 <0.05 <0.05 <0.011 2006-09-07 <0.005 <0.05 <0.05 <0.010 2006-09-08 <0.005 <0.05 <0.05 <0.010 Concentration limit 0.05 0.5 0.25 4.5 of leachate Refer to Standard for Pollution Control on the Landfill Site of Domestic waste (GB16889-2008) for concentration limit of leachate. Feasibility analysis of landfill of fly ash solids According to Standard for Pollution Control on the Landfill Site of Domestic waste (GB16889-2008), domestic waste incineration fly ash can satisfy the following conditions after treatment, and can be disposed in domestic waste landfill. (1) Water content is less than 30%; (2) The content of Dioxins is less than 3μgTEQ/Kg; (3) The concentration of harmful ingredient in leachate prepared based on HJ/T300 is lower than specified limit. As analyzed according to properties of fly ash, water content, Dioxins content and concentration of harmful ingredient in leachate after solidification of fly ash can be up to the standard for control, therefore, it is feasible for disposal in waste landfill. Solidified fly ash is delivered to supporting domestic waste landfill for disposal; before completion of supporting domestic waste landfill, solidified fly ash is sent to Danyang Waste Landfill for treatment. (3) Others Other solid wastes mainly include metal wastes, ion exchange resin waste, used oil, sludge from wastewater treatment and domestic waste. Metal wastes of the Project come from urban waste, which are absorbed out by magnetic separator equipped on the tapping conveyor in the slag exhaust system, and part of the wastes are sold to iron and steel works. Ion exchange resin waste and used oil are dangerous, so Zhenjiang Shengjie Waste Oil Comprehensive Utilization Co., Ltd is entrusted for treatment. Sludge from wastewater treatment and domestic waste are treated in incineration system of the Project. According to Standard for Pollution Control on Hazardous Waste pit (GB18597-2001) and Policy for Pollution Prevention on Hazardous Waste, the construction unit must set special stockyard to store and control take measures to prevent their spreading, running out and leakage; designate professional personnel for operation; collect, store and transport individually; prepare pollution prevention and emergency measures in transfer and transportation of hazardous wastes, and strictly go through the procedures as required. The above solid wastes basically have no influence on the surrounding and human beings, and also may not cause secondary pollution after being treated strictly complying with the above measures, so these measures are feasible and effective.

8.4.2 Feasibility analysis of temporary measures for fly ash treatment The auxiliary landfill is in the east of Jianbi ash silo about 1.5km from the Project site. It will be completed and put into operation in the end of 2010 as planned (the commitment of Zhenjiang Urban Management Bureau and schedule are shown in attachments); the Project also will be put into operation at the same time if there is no accident. However, there may be uncertain factors in construction of the landfill, so it is possible that the construction period may be delayed. So temporarily measures will be taken for fly ash treatment: if the auxiliary landfill cannot be completed on time, solidified fly ash will be sent to Danyang Waste Landfill for treatment before its completion (if the auxiliary landfill is completed in advance of the Project as planned, it will be treated in the landfill directly). Danyang Waste Landfill, also named Danyang Maojia Wastes Disposal Center, belongs to Danyang Jiajie Environmental Sanitation Services Co., Ltd. The Provincial Environmental Protection Administration gave an official to environmental assessment of the Project in July 2005; Phase I Project was commenced in March 2006, which was completed and put into operation in October 2006; in 2007, the Phase I Project has passed the “3-Simultaneity” acceptance for environmental protection organized by the Provincial Environmental Protection Administration and no-harmful grade estimation of domestic waste landfill organized by the Provincial Construction Administration, and it was crowned as National Grade I. Danyang Waste Landfill is located in Situ Town of Danyang City, is about 10km from the Project. Total design storage capacity is 1.4 million m3, and it will be constructed through three phases (the environmental assessment approved by the Provincial Environmental Protection Administration in 2005 covers all the three phases); total design service life is 12-15 years. At present, storage capacity of Phase I is 400 thousand m3 and it is now to be completed and sealed; that of Phase II is 500 thousand m3, it is now under construction and was put into operation before 2009 year end.

The Project will be completed and put into operation in the end of 2010 as planned. Till then, Phase II Project of Danyang Waste Landfill should have been put into operation; so the time for putting into operation can be ensured. Design daily waste landfill capacity of Danyang Domestic Waste Landfill is 500t, at present its actual capacity is 400t. After the Proejct is put into operation, some waste in Danyang City (about 300t/d) also will be incinerated here. Therefore, daily waste landfill capacity of Phase II of Danyang Waste Landfill is 500t, estimated daily waste landfill capacity is 100t after the Project is put into operation, there is 400t/d residual landfill capacity reserved. Output of fly ash of the Project is about 60t/d taking up 15% of the residual landfill capacity of Phase II Project. Total storage capacity of Phase II and Phase III is 1 million m3, it can provide service for another 17 years as calculated according to 160t/d waste landfill. Even taking no consideration to reduction of Danyang waste landfill, it also can serve for at least 9 years as calculated according to the original total design service life. Leachate of garbage in Danyang Waste Landfill is connected to Shicheng Sewage Treatment Plant for centralized treatment through municipal wastewater pipework after being up to standard through pretreatment by three-level mineralization bed process. Pretreatment facilities for leachate of garbage in Danyang waste landfill have been constructed, according to three-step acceptance materials of the Provincial Environmental Protection Administration: leachate of waste can be up to the standard for connection standard after pretreatment. (see environmental protection of three-step acceptance materials for detail.) Total design capacity of Danyang Shicheng Wastewater Treatment Plan is 80 thousand ton wastewater per day as planned, that with 80 thousand ton treatment capacity has been constructed at present; dephosphorization and denitrogenation upgrade modification Project was accomplished in 2008. The three-level treatment process namely “Three-groove oxidation channel biochemical treatment+ aeration biological filter+filtering” is applied at present, tail water is discharged into Beijing-Hangzhou Canal, Grade I Type A standard of Discharge Standard of Pollutants for Municipal Sewage Treatment Plant (GB18918-2002) is implemented. Tail water discharge of Shicheng Sewage Treatment Plant (80 thousand t/d) has less influence on the gound water according to Environmental Impact Report of Danyang Shicheng Sewage Treatment Plant. In a word, taking the time for Phase II being put into operation, daily waste treatment capacity and service life into consideration, Danyang Domestic Waste Landfill can accept solidified fly ash of the Project. Moreover, it is equipped with perfect environmental protection facilities, and is experienced in operation and management of leachate treatment facilities; fly ash of the Project causes less impact on the environment after being treated at Danyang Domestic Waste Landfill.

8.5 Groundwater pollution control measures and assessment In order to protect groundwater resource, anti-seepage measures also shall be taken into account for waste pit, leachate tank and treatment station in design of the Project. The floor of diesel oil reservoir area and ash silo shall be hardened with cofferdams (bounding walls) around them. Anti-seepage measures for waste pit As for waste pit, not only soil pollution and bar corrosion arising from seepage of leachate shall be avoided, influence on water content of waste and bar corrosion arising from seepage of external water also shall be cared. Therefore, the crack width at the bottom and in wall structure shall be controlled not more than 0.2mm through calculation firstly. Then the following measures shall be taken: Mix certain concrete expansion additive in concrete, and also mix necessary steel fiber or synthetic fiber to ensure in-house waterproofing of RC structure; Apply cement-base infiltration and crystallization waterproof coating on inner wall and base plat of tank; Set a high polymer modified bitumen waterproof roll both outside the wall and under the base plate. Anti-seepage measures of leachate treatment station Constructions of leachate pit are of RC structure and applying several ways for seepage prevention including cement motor layer, thick steel epoxy glass isolation layer, two thick macromole compound waterproof rolls, waterproof anti-seepage RC layer and thick epoxy mortar top layer. Piping installation shall strictly comply with codes, connections shall be tight and smooth, padding shall be compact, so as to avoid damage and even groundwater pollution. In construction, anti-seepage terrace shall be constructed on the floor of production area. Take anti-seepage measures and construct anti-seepage terrace for wastewater collection pipes, wastewater storage, wastewater treatment facilities and waste pit places. The anti-seepage terrace mainly has three layers, accounting from the bottom, the first layer is 30-60cm thick soil and stone mixture, the second layer is 16-18cm thick two-lime stone and the third layer at the top is 20-25cm thick concrete. Taking the above measures can effectively prevent downward seepage of wastewater and groundwater pollution, which can reduce the influence of groundwater on the environment.

8.6 Greening It is necessary to strengthen greening in the plant, improve greening rate and set up isolation protection forest. Trees and grassland not only can absorb carbon dioxide, sulfur dioxide, nitric oxides and dust, but also can absorb and stop noise in a certain degree, so we shall try to do well greening work, increase greening area, try to create a beautiful and comfortable work environment and reduce influence on the external environment. Greening zones in the plant are arranged reasonably, for example, select plants of strong resistance and be able to absorb pollutants, plant arbors, shrubs and grasses in a mixed way, plant suffrutex and grassland inside the protection forest for ventilation, select high broadleaf species with high density to cover the whole plant in green groves. Greening area of the Project is 23960m2 and greening rate is up to 29.95%.

Analysis of public opinions is as follows: (1) Respondents are widely distributed, and their age and level of education are quite representative. Most of them are local residents including peasants. Since they are directly affected by the construction and more familiar with the local environment as well as its humanistic and social settings, they are able to propose such advices that can fully represent the opinions of this region. (The others are corporate staffs mainly living in downtown Zhenjiang within the range of the evaluated project)

(2) Most of Respondents who participate in the investigations are satisfied with the environmental quality, accounting for 82% of the total (164 persons); those who are unsatisfied are 32 persons, accounting for 16%; and those who are extremely unsatisfied are four persons, accounting for 2%. (3) The Respondents within the region have already obtained some knowledge about the project: 56% (112 persons) know a little about the construction of this project, 18% (36 persons) know quite a lot about the ongoing project, but 26% (52 persons) do not know this project. Among them, 45% know it through newspaper, 26.5% through TV/Radio; 8% through posters and 20.5% through non-governmental channels. This indicates that the diverse promotion of the enterprises and related government sections is effective. However, some respondents are still unclear. Hence, efforts should be made to strengthen the promotion so as to acquaint the residents within the project site or in the peripheral area of this project with the construction circumstances and its related supporting works. (4) Four persons think that this project shall make serious impacts on the environmental quality, accounting for 2% of the total; 43 persons think that it shall make very serious impacts, accounting for 21.5%; 36 that it shall exert a general impact, accounting for 18%; 101 persons believe that it only has a little impact, accounting for 50.5%; 16 persons are unclear, occupying 8%. (5) According to the feedback questionnaire, 64% of the local people (128 persons) agree with the construction, 36% (72 persons) absolutely agree with it without any opposition. This indicates that the construction has virtually won the support of the local community. Many express that they will support the project under the condition of well-built infrastructure facilities as well as successful maintenance and operation (5) Advices and requests of the publics on environmental protection under and after the construction of this project. Authorities of environmental protection should examine and approve the project strictly in line with related laws and regulations as well as the pertaining program, fulfill the antipollution measures and reflect effective supervision.

Enterprises should form feasible control programs, conduct controls of “three wastes (waste gas, wastewater and waste residues)” with high 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant threshold and high standards, and forbid producing new pollution in the course of curbing pollution. ○3 All antipollution incentives should be adopted properly and “discharging up to the standards” should be firmly adhered to, so that no impact can be done to the normal life of the residents. ④ Authorities of environmental protection should reinforce environmental controls and its monitoring and supervision during the operating period of the project, and then conduct spot check at all times. 10.5 Public Participations in Discussion

Chart 10.6-1 Pictures of the Hearing Meeting Onsite See the details of discussions in the appendix. The general idea of supplementary suggestions of the representatives is: in combination with “New Socialist Countryside Construction”, prioritize the planning and relocation of the residents near the Chemical Industrial Park in New District and help the residents living in the project area move as soon as possible; the enterprise should adopt advanced technology and administration to honor credibility and live up to its words; the government should fully perform its supervisory duty.

10.7 Summary of Public Participations in Investigation Overall, feedback of public participations in investigation indicates that: parts of the local community in the planning site are satisfied with the general environmental quality of the region. And this project has won understandings from the majority of the local residents. None expressed objections. Moreover, some residents only showed conditional support, and their requirements can be summarized as: this project should be administrated rigidly; all of the pollutants should be discharged up to the standards; and the function area should reach the standards to avoid any interference to the normal life of local residents.

In response to the demands of the representative who showed conditional support in the investigation with public participations and to their concerns of the environmental impact of this project, in the and after construction of the project when it goes into production, the enterprise and the government should attach great importance on environmental protection, implement all control measures of waste water, exhaust gas, noise and solid wastes listed in the Report on Environmental Assessment, strengthen environmental controls to guarantee the reliable discharging of pollutants and the function area reaching to the standards, so as to make the construction fairly feasible. Meantime, the enterprise should strengthen the publication of the project and regularly publicize the environmental quality data of the surrounding area so that the community can have a clearer and better understanding on its antipollution incentives and environmental impact.

11 Environmental Economic Cost-Benefit Analyses Development construction of the planning project shall certainly boost the local societal economic development. On the other hand, it shall also bring inevitable harms to the planning site and its environment. Under the construction, utilization of necessary environmental protection 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant measures can partly ease off the unfavorable influence and the economical losses brought by the project construction. By analyzing on the societal, economical, environmental benefit as well as environmental cost brought by the project, this chapter shall make a concise analysis on the environmental economic cost and benefit of this project.

11.1 Economical Benefit Analysis on the Project Investment

This project was partly financed by loans and partly by the enterprise itself, the investment totaling up 41.33383 million Yuan. Major economical indicators have seen Table 11.1-1.

Table 11.1-1 Major Economic Indicators Item Unit Index Cost of Electricity-selling Unit Yuan/ Mwh 505 Annual Sales Revenue RMB 10k 7071 Annual Sales Profit RMB 10k 5382 Internal Rate of Return (Pre-Tax) % 8.20 Internal Rate of Return (After-Tax) % 7.10 Payback Time for The Investment (Pre-Tax) Annual 11.53 Payback Time for the Investment (After-Tax) Annual 12.04 Note: electricity-selling cost, sales revenue, sales profit and so on are exclusive of tax; payback time for the investment incorporates two years of construction period.

It can be concluded from Table 11.1-1, internal rate of return, payback time for the investment and other indicators of this project are fairly good and the project only has a small risk.

11.2 Investment in Environmental Protection It can be concluded from the project analysis and environmental impact prediction, after the planning project is completed and put into production, waste water, exhaust gas and noise shall exert certain impact on the surrounding environment. Hence, corresponding environmental protection measures should be adopted to guarantee corresponding environmental protection investment, thereby minimizing the environmental impact to the smallest degree. Investment on environmental protection of the planning project sees Table 8.7-1 according to the preliminary estimate. The total investment of this project is 41.33383 million Yuan, among which 7.47663 million Yuan, 18.12% of the total, is environmental protection investment.

11.3 Environmental Economic Cost-Benefit Analysis This project adopts improved and reliable control measures for exhaust gas, waste water, noise and solid castoff to minimize the quantity of pollutants entering into the environment, thereby yielding considerable environmental benefit, including: fumes cleaning plans to adopt series connection of semi-dry neutralizing tower and bag deduster to guarantee discharging of incinerating gas to reach the standards; the trash landfill leachate and rinsing waste water shall be processed in the sewage treatment station to reach the standards for taking over so as to be sent with other waste water to Dagang sewage treatment plant for further treatment; after adopting a series of noise reduction measures, boundary noise can reach the standards; all solid trash produced by this project will be properly handled or utilized comprehensively. Harm of “the three waste” 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant shall also be distinctly downsized after adopting these measures. Besides, thermal power generation produced by incinerating trash shall reclaim domestic waste to yield better environmental and economical benefit.

11.4 Societal Benefit Analysis According to the national policy of trash disposal –“recycle, reduction and hazard-free treatment”, trash incineration is a desirable way for city refuse disposal. Over recent years, many cities in China had built refuse incineration power plants, and some had obtained good operating experiences and yielded considerable benefit. Construction of this project accords with the national policy of refuse disposal. First of all, after incinerating domestic waste, size of the slag and fly ash only accounts for about 15~ 19% and 2% of the total, realizing the demand of substantial weight reduction and letting out considerable size of trash piling ground. Secondly, a great quantity of harmful substances turns into ashes after high-temperature incineration in the incinerator, thereby substantially reducing its toxicity

The planning project, if completed, on the one hand, can solve the urban domestic waste problem which looms larger increasingly: large quantity of waste dump in the suburbs not only takes up masses of plow land and affects the city landscape, but also brings pollution to the water, air and soil environment, posing danger to the living environment of urban and rural residents. The project shall settle the problem of mounting quantity of domestic waste which now confronts the Zhenjiang people. On the other hand, the benign cycle of waste reclamation can improve the local investment environment and contribute to the local societal economy by yielding favorable societal benefits.

Overall speaking, this project is an environmental protection project for public welfare. Trash incineration disposal, thanks to its advantages of thorough hazard-free, conspicuous lightened and comprehensive reclamation of remaining heat and slag, is a desirable way to dispose urban domestic waste in China during recent years. Construction of this project can solve the problem of increasing urban domestic waste. And the implementation of this project will have patent benefits in boosting sustained development of the economy and society of Zhenjiang City. 12 Environmental Control and Monitoring Plan 12.1 Environmental Control 12.1.1 Basic Objective of Environmental Control This project shall have certain impact on surrounding environment in the construction and operation. Environmental measures should be taken to mitigate and eliminate adverse environmental impact. To ensure that environmental protection measures could be earnestly carried out and societal, economical and environmental benefits of the project can coordinately develop, efforts should be strengthened in environmental controls to make the project construction accord with the strategy of synchronized planning, implementation and development in terms of economical construction, societal development and environmental construction.

12.1.2 Management Responsibility and Measures

It is suggested to set up 2~6 full-time environmental protection management personnel to take charge of environmental controls of the corporation as well as external harmonization work of environmental protection, i.e., fulfilling the duties of environmental management and environmental monitoring duties, which can be stated as follows:

12.1.2.1 Environmental Management Responsibility (1) Implement thoroughly environmental protection laws, regulations and standards.

(6) Based on environmental monitoring, establish the pollution source document to find out the emission quantity, emission source intensity, emission law and related pollution control as well as their comprehensive utilization measures.

12.2 Environmental Supervision Principle of environmental supervision in design stage Supervision for the design quality is subject to the program administration of the design organization. The design organization of this project has formed a complete program of checking and reporting for approval in accordance to the policy of “prevention in the first place, integrating prevention with control and comprehensive control”. Major content of environmental protection supervision is as follows: Environmental protection measures or plans and the budgetary estimate of required environmental protection measures investment should be stated in the preliminary design documents or in the shop drawing.

The design document should stipulate covering measures to guard against ash pollution in delivering or piling construction materials. In dry seasons, it should be prescribed to sprinkle water or take other dust reduction measures in good time to alleviate dust emission pollution. On-the-spot supervision for all kinds of pollution sources in construction stage Project in bidding stage Environmental protection should be written into the corresponding provisions in the contracts of the bidding documents. Its copy should be submitted to the environmental protection supervisory engineer who shall check for reference while implementing on-the-spot supervision. On-the-spot supervision for all kinds of noise source On the spot environmental protection supervisory engineer should supervise and monitor the environmental noise affecting the buildings with acoustical intensity sensitivity in the construction site. And if the monitoring result exceeds the required environmental noise quality standard, the environmental protection supervisory engineer should notify the contractor to adopt noise abatement measures or to adjust the mechanical construction time. on-the-spot supervision for environmental air pollution source 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant Environmental air pollution sources include dust emission of construction sand, stones, mixed aggregate stacks and those produced from transporting aggregates which can exacerbate pollution to the environmental air. The on-the-spot environmental protection supervisory engineer should monitor the environmental air quality on the surrounding points with environmental air sensitivity to check the pollution degree of the above-mentioned pollution sources. If the monitoring result exceeds the required environmental air quality standards, environmental protection supervisory engineer should notify the contractor to adopt precautionary measures to confine the values to the standard limit value. On-the-spot supervision for water pollution source Water pollution sources include: waste water produced in the course of construction, life waste water emitted from the dwelling places of the construction, supervision organizations, and waste water discharged from the mixing plant (station) in construction which will directly cause pollution to the pollutant-holding water body. To check the pollution degree of the afore-said water pollution sources to surface water such as pollutant-holding waters, environmental supervisory engineer should supervise and monitor related items of the water environmental quality in the construction spot. If the monitoring result exceeds the required water environment quality standards, environment supervisory engineer should notify the contractor to adopt control measure to confine the values to the standard limit value. Construction quality supervision for the environmental project facilities The environmental project facilities mainly include: fumes disposal system, waste water disposal facilities, plant afforesting facilities and so on. Construction of these environmental project facilities are mainly structure projects and garden construction. Supervision of construction project quality falls under the project quality supervisory engineer and the garden technician. Environmental supervision should focus on that whether the environmental effect of the facilities of the environmental project attains the designed requirement. If it cannot attain to the designed demands after monitoring, they should notify the contractor to take remedial measures at an early date until it reaches the designed requirements.

12.3 Environmental Monitoring Plan 12.3.1 Objective of Monitoring Environmental monitoring is the paramount link and technological support in environmental protection. Environmental monitoring aims to: (1) Inspect the protection for the exposed construction surface during the construction period and the environmental problem such as construction dust emission, construction waste water so that they can be timely handled. (2) Inspect and track the implementation and effect of all environmental protection measures after the project going into production and grasp the developments and changes in environmental quality. (3) Comprehend the operation the facilities of the environmental project to guarantee normal operation. (4) Comprehend the execution of related monitoring for environmental quality . (5) Offer technological supports to improve the surrounding environmental quality

12.3.2 Monitoring Content Refuse incineration power plant should be equipped with necessary equipments and instruments. The model and specification of specific equipment and instrument should be stated clearly in the preliminary design. The specific monitoring plan is as follows: 12.3.2.1 Atmospheric Environmental Monitoring Before going into production Before the proposed project going into production, the construction unit should set up one check point respectively at the sensitivity point nearest the down wind of the predominant wind direction of the whole year and at the point with the largest pollutant ground level concentration within the plant to conduct dioxins monitoring; set up one soil dioxins monitoring point respectively at the up wind and down wind of the predominant 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant wind direction of whole year. For the down wind point, planting soil near largest pollutant ground level concentration is recommended. According to the predictions of atmospheric environmental impact and circumstances the surrounding environmental sensitivity points, the dioxins atmospheric sampling points are selected at Chenjiazhuang and Yubei Village. And soil sampling points are selected at the planting soils of Xiadian and Chenjiazhuang. After going into production Monitoring points ● Fumes monitoring According to The Determination of Particulates and Sampling Methods of Gaseous Pollutants Emitted Gas of Stationary Source (GB/ T16157- 1996) and Technical Norm for Continuous Emissions Monitoring of Fumes Emitted from Thermal Power Plants (HJ/ T75- 2001), the fumes sampling points for the trash incinerator should be set up on the straight tube of the vertical chimney. Moreover, Reserve a manual sampling hole under 0.5 m of the soot monitoring hole for regulation. ● Environmental monitoring The dioxins atmospheric sampling points are selected at Chenjiazhuang and Yubei Village. And soil sampling points are selected at the planting soils of Xiadian and Chenjiazhuang. Other factors can be referred to the original environmental assessment layout. monitoring items SO2, PM10, NOX, HCl, CO, NH3, H2S, odor concentration and dioxins monitoring plan ● Combustion temperature, oxygen level, applied dosage of active carbon of the trash incinerator. Adopt fumes on-line monitoring instrument to monitor the emission density of soot, SO2, NOX and CO ● Monitoring period for emission quantity monitoring of HCl for the trash incinerator is once per quarter. Qualified organizations should be entrusted to monitor emission quantity of dioxins, Hg, Pb and Cd in trash incinerator annually. Conduct regular monitoring PM10, SO2, NOx, HCl, NH3, H2S and odor concentration of production area and the surrounding sensitive protection targets (selecting two down wind sensitive protection targets according to the wind directions). Regularly monitor the dioxins in the soil.

12.3.2.2 Water Environmental Monitoring Regularly monitor the import and export of waster water treating station to ensure that the purification efficiency reaches the standard requirements for the water treatment facilities so as to avoid accidental emissions. Besides, monitor the rainwater collection system in the plant.

Monitoring items: pH, SS, COD, BOD5, fecal coliform, volatile phenol, Cr6+, AS, Pb Cd and Hg

Monitoring time and frequency: four times per year, after the project goes into production.

Monitoring frequency inside the enterprise is once every day. Its monitoring items are pH value and COD. Set up flow rate and COD on-line monitor.

12.3.2. 3 Noise Monitoring Monitoring time and frequency: after going into production, conduct one monitoring period per month and every period lasts for two days, one in the daytime and the other in the nighttime. Increase monitoring times according to the actual situation. And the monitoring times cannot be 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant lessened. Timely report the monitoring result of major pollution sources, operation and utilization situation of facilities like fumes handling and waste water treatment to related environmental protection institutions so that all levels of environmental protection institutions can grasp the actuality of environmental protection of the life refuse incineration power plant and the operational status of equipments. On the other hand, the local people can also learn the actual environment protection status of life refuse incineration power plant via the competent government authority, thereby easing off the concerns of the community with the environmental protection problem of the refuse incineration power plant. Hence it can play the supervisory role.

To fully grasp the emission and the impact degree of the project pollutants to the surrounding environment, it is advised that the plant to conduct retrospective environmental impact assessment after three or five years after the project goes into production. 12.3.2.4 Monitoring of Solid Leaching Solution of Fly ash

As hazardous solid wastes, fly ash cannot be sent to the refuse landfill for landfill treatment unless it is solidified to reach the demands of related standards. After the proposed project is built, the construction unit should monitor the leaching solution of the solidified fly ash body annually. The monitoring items mainly include moisture content, dioxins content, toxic content density of all kinds of heavy metal in leaching solution. The solidified fly ash should match the requirements and standards in Standard for Pollution Control on the Landfill Site of Domestic waste (GB16889- 2008). Monitoring result of leaching solution of the solidified fly ash body should also be incorporated into the daily supervision work of Authorities of environmental protection.

12.4 Suggestions on Standardization of Sewage Draining Exit Sewage draining exit installation of this project should conform to the requirements of standardization of sewage draining exit stipulated by department of environmental supervision. (1) Wastewater outlet (sewage inlet) Sewage draining exit of this project should be set up at outside of the waste water station within the plant boundary. The outfall should be convenient for conducting sampling and discharge measurement： Ordinary outfall shall be installed according to the size of sewage discharge with reference to the related requirements in the Size Table of Adaptable Sewage Outfalls. A meter should also be installed. If the sewage surface is one meter higher or lower than the ground, a sampling platform or a ladder (with a width no less than 800 meters) should be added. If the sewage directly discharges into the municipal pipelines through underdrain, a sampling point (radius > 150mm) should be set up at the section before it goes into the municipal pipelines within the plant boundary. Sampling valve should also be installed at the sewage conduit with pressure. And monitoring device should be installed at the secondary sewage facilities. (2) Exhaust gas outlet Exhaust gas outfall should conform to the required height and the requirements of convenience for sampling and monitoring according to Technical Norm for Pollution Source Monitoring. Permanent sampling holes should be installed at the chimney or flue of the incinerator. And a sampling monitoring platform should also be fit up. The sampling hole shall be decided jointly by Environmental inspection detachment and environmental monitoring center. (3) Fixed pattern noise emission source According to related regulations, control the fixed pattern noise and set up sign plates at the boundary noise sensitivity points which could exert great harm to the external environment. (4) Solid waste pit (disposal dump) Respectively collect, store and transport different solid waste and put up special piling places take measures to prevent the scattering, running off, 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant leaking and seeping of solid waste, as well as other measures against environmental pollution and regularly supervise the flyash of hazardous waste by incinerating trash. (5) Requirements for installing sign boards Graphical symbol of environmental protection is wrought by State Bureau of Environmental Protection at fixed places. The environmental supervision department orders the graphical symbols from the State Bureau of Environmental Protection according to the sewage discharge situation of the factories. The enterprise sewage draining exit distribution map is tailored by the Environmental inspection detachment. Install prompt sign board at the ordinary pollutants outfall (sources) and warning sign board at the sewage draining exit which could emit toxic or hazardous pollutants.

Sign plates should be set up at an arresting place in the vicinity of sewage draining exit (sampling hole). The upper side of the sign plate should be two meters high. Install plane sign plates at the sewage draining exit which has buildings within one meter range and erect sign plates at the sewage draining exit without buildings in the neighborhood.

Standardize the installations of sewage draining exit (such as graphical sign board, meter installation, monitoring installation and et cetera). Since all of these facilities are for environmental protection, the sewage institutions should conduct daily maintenance and no organization or individual has the right to dismantle them without authorization.

12.5 Environmental Controls, Monitoring and Monitoring Requirements Environmental Controls measures, monitoring measures and monitoring plans of the proposed project by the construction unit shall be improved or augmented in the following aspects: A. Subdivide the work of environmental controls set up special environmental controls system and incorporate it into the prioritized control works of the whole plant. B. Add special posts to conduct Environmental Controls work, enhance the efforts of input and administration C. Drawing from the experience of other refuse incineration power plant, install fumes automatic monitoring display screen at outside of the plant and accept supervision from the community at all times to guarantee “discharging up to the standards” of the exhaust gas pollutants. Meantime, establish a public supervision committee which convenes regular meetings, initiates inspections and discussions and accept public supervision so as to improve environmental controls level itself and mend the relationships with the neighboring community by enhancing mutual understanding. D. The applied on-line monitoring system is imported brands articles which are recognized by former State Environmental Protection Administration (namely Ministry of Environment Protection). Since it has successful experiences in domestic refuse incineration power plant, we have confidence in its reliable operation. The on-line monitoring system transmits data to the municipal environmental protection bureau via internet, with a time interval of one minute. E. Install a chromatic industrial television monitoring system in the plant to monitor the following items: (1) trash charging in the trash discharging hall;(2) trash stockpile of waste pit;(3) fragmentation of large items; (4) feeding of the refuse cabin in cast house;(5) ignition monitoring of the incinerator;(6) flame in the hearth of the incinerator;(7) boiler drum level;(8) the exit of slag extractor ;(9) steam turbine operating layer;(10) circulating pump house;(11) chimney and et cetera. F. Management for environmental protection monitoring data includes: the system automatically store historic monitoring data; the engineer regularly makes copies; tailor special datasheet for the operator so that he or she can check data of any time period to monitor environmental protection indicators; communicate on the accuracy of data with environmental protection bureau, who shall send professionals to the plant to conduct inspections. 镇江市生活垃圾焚烧发电厂 BOT 项目环境影响报告书 The Report of Environmental Impacts on the BOT Project of Zhenjiang Waste-To-Energy Power Plant G. This project conducts background monitoring on dioxins atmospheric environment according to the requirements of Huanfa No. 82, 2008 Document. After the project goes into production, conduct regular monitoring for dioxins to inspect the changes of dioxins. H. As to monitoring of pollutants such as dioxins, department in charge, not only conduct regular monitoring according to national regulations, but also do spot tests without a fixed schedule and keep the promise that dioxins emissions shall be up to the standard

13 Feasibility Analysis of Site Selection According to Huanfa No. 82, 2008 Document, there are corresponding regulations and requirements on program conformity, environment sensibility of site selection, model of equipment, emission standards for pollutants and other aspects for domestic waste power project. This chapter shall conduct feasibility analysis focusing on related requirements of the document.

13.1 Background of the Proposed Project According to requirements of Ministry of Construction, State Environmental Protection Administration (SEPA), Ministry of Science and Technology (Jiancheng No.120, 2000), the waste power is applicable to regions where average low heating value of the feeding trash is higher than 5000 kJ/ kilogram, sanitary landfill is insufficient and with flourishing economy. Urbanization of Zhenjiang City continuously accelerates, but the city trash grows larger and larger in quantity. Based on the data provided by Zhenjiang Department of Environmental Sanitation, in 2000-2003 the city produced 575.94 tons of trash everyday. With the municipal development, daily disposal quantity of domestic waste of Zhenjiang City shall attain more than 1500t. The refuse landfill in the east of the city disposing about 700t/ d clearly can not meet the needs of the refuse disposal of the whole city. Moreover, the trash sanitary landfill in the east of the city only last until 2010. At present, the domestic waste disposal can only adopt landfill treatment to eliminate toxicity. And the degree of weight reduction and reclamation is relatively low, lagging behind with the demands of the whole societal economical level and development of Zhenjiang City. It is quite necessary to build a refuse incineration power plant to adapt to the requirements of disposing domestic waste with “reduction, recycle and hazard-free treatment”, which helps to construct the civilized eco-environment

13.2 Consistency Analysis with Related Programs and Regulations Conformity Analysis with The Overall Program of Zhenjiang City(2002-2020 year) According to The Overall Program of Zhenjiang City (2002-2020), Zhenjiang City aims to “develop into a charming, refined and dynamic city of fame with substantial economic strength as well as a modern cultural city with fully-developed societal undertakings in the south of the Yangtze River”. One of the goals of municipal construction is: “to build a infrastructure service network corresponding with the societal economic development”. Building a refuse incineration power plant at a place concentrating on developing port, industry and logistics to protect the environment hygiene of Zhenjiang City matches the needs of municipal function

Part Eight “Program for Environmental Sanitarily Facilities” in Chapter Twelve “Program for Public Municipal Facilities” also clearly proposes to build a trash incineration plant. Therefore, construction of this project tallies with The Overall Program of Zhenjiang City.

supporting living facilities constructions of this project which tallies with Development Strategies for New District of Zhenjiang City.

See the planning map for Zhenjiang New District land use in Chart 3.1-1

Conformity Analysis with Land Use Program The site is located at the south of Datie Street, west of Zhencheng Road in New District Town, Zhenjiang City, outside the main city zone and the built-up district in keeping with the requirement in No. 82 document that under normal conditions, constructions in built-up districts in large and medium cities are forbidden. In the light of the land use planning map in The Overall Program of Zhenjiang City and Development Strategies for New District of Zhenjiang City, the planning ground of this project is industrial land in the program. The land used by this project has already been approbated preliminarily by Zhenjiang Planning Bureau. (See appendix). Compatibility Analysis with Program for Jiangsu Key Conservation Districts with Ecological Function Referring to Program for Jiangsu Key Conservation Districts with Ecological Function, the planning ground used by this project is not a key conservation district with ecological function “not belonging to Jiangsu Province”. The conservation district with ecological function nearest the project is No. K06 Changlongshan Ecological Forest .The forbidden zone is 0.27 square kilometers and others are the restricted zone. The leading ecological functions are conservancy for nature and artificial scenery as well as biological diversity. Its shortest distance with the project is 600m. See its specific position in Chart 1.7-1.

In the light of Program for Jiangsu Key Conservation Districts with Ecological Function, the protective measures for Ecological Forest are “all activities irrelevant with conservancy in the forbidden zone are prohibited. Reclamation, quarrying, digging sand, borrowing soil, building tombs, commercial logging, chopping wood, tapping tree, hunting and other acts are prohibited in the restricted zone. Land suitable for tree planting such as waste mountains and land and burned area should be afforested to recover vegetation within a time limit. And those built projects which have damaged the ecological function of the ecological forest should be relocated or rectified within a time limit”.

Overall speaking, the planning ground is not situated within the range of the forbidden zone and the restricted zone of Changlongshan Ecological Forest. Atmospheric pollutants of this project, after the treatment, could yield less quantity. Atmospheric prediction manifests that exhaust gas of this project only has a rather small impact on the environmental air quality (including Changlongshan Ecological Forest). Therefore; this project is compatible with Program for Jiangsu Key Conservation Districts with Ecological Function.

(2) Impacts of Ground-water Environment The leachate of the waste and washing water will be sent together with domestic sewage to the Dagang Sewage Disposal Plant for concentrated treatment through municipal sewage pipeline network after meeting the taken-over standards through the treatment by the self-built leachate treatment devices. The added discharged amount of sewage within the acceptable range of the Dagang Sewage Disposal Plant is discharged after the disposal by the Dagang Sewage Disposal Plant, which has little effect on the quality of ground water. (3) Impacts of Acoustic Environment The completed project will make the acoustic environment of the plant limits meet the standards through proper arrangements and effective measures for noise reduction. There will be no acoustic-environmentally sensitive objects within 300 meters of the plant limits, which poses no hazard of disturbance to the residents nearby.

14.4.3 Impacts of Environmental Risks The toxic, combustible and explosive materials involve in the project are light diesel, HCl, CO, NH3 and H2S. Three occasions need to be taken into account for the environmental risks in the process of the production of the planned project: the first is when the auxiliary flue-gas treatment devices of the incinerator breaks down; the second is when accidents occur which results in the shutdown of the 3 incinerators; the third is when the explosion caused by excessive CO in the incinerator has effects on the ambient environment. The periphery of light diesel storage tank will be set the accident cofferdam to ensure that all the diesel of the storage tank can be limited within the cofferdam in the case of accidents and be kept off the ground water environment. The results of the faults and accidents estimation for flue-gas disposal facilities indicate: in the case of accidental emission, the effects the dioxins on ambient environment are more than the normal condition but meet the 江苏省环境科学研究院 17 Jiangsu Provincial Academy of Environmental Science

requirements of related assessment standards and lower than the tolerable intake amount of 4pgTEQ/kg by the human body and the allowable intake amount via respiration effect is lower than the 10% of the level of daily tolerable intake amount. In the case of accidents, the cacosmia will be treated by the activated carbon and discharged through 80m-long chimney with smaller emission amount and slighter effects on ambient environment. Management is required to be strengthened for this project, preventive measures should be strictly implemented for various accidents raised by the report and emergency response pre-scheme should be devised to eliminate various accidents and avoid the pollution in the local areas. In the whole, after the completion of project in planning, the level of risks can be acceptable on the basis of the guarantee for the implementation of preventive measures for environmental risks.

14.5 Preventive Measures for Pollution and Assessment 14.5.1 Sewage The discharged cycling cooling water is reused as supplementary desalination water and for washing activities for dust van, unloading platform and ground road; anti-infiltration water prepared for desalination is reused for the slag cooling and solidification of flying ashes; regular drainage is reused as the supplementary water for the cooling tower. The leachate of the waste and washing water will be sent together with domestic sewage to the Dagang Sewage Disposal Plant for concentrated treatment after meeting the taken-over standards through the treatment by the self-built leachate treatment devices. ◆ Conclusion of Assessment on Preventive Measures for Sewage Pollution After the waste leachate going through the pre-processing, the project can completely reach the taken-over standards of the Dagang Sewage Plant, so can the sewage of the project in water amount and quality. 14.5.2 Exhaust Gases (1) Treatment Measures for Incinerator Exhaust Gas Measures to control the generation of dioxins and furan include: a. Each incinerator is installed with one set of diesel combustion-supporting system; b. Firepots and fire grates with reliable and sophisticated technologies are applied to achieve sufficient combustion of waste in the incinerator. The techniques adjust the air flow, rate and location of injection and reduce CO and carbon element to cut the concentration of dioxins. c. Through “Three-T” controlling method, most of the original dioxins in the waste can be decomposed. d. To reduce the time for the fumes suspending in the 300~500℃ location in the process of disposal and discharge and limit the discharge temperature of excessive heat within 200℃; to apply the bag deduster to the flue-gas dust elimination to reduce the re-synthesis effects of dioxins. e. To apply the flue-gas disposal system integrating semi-dry neutralizing tower with the bag dust catcher to make hazardous organic pollutants condensed onto the fly ashes, and the bag dust catcher can remove these organic substances while carrying out the dust catching activities. Meanwhile, the activated carbon ejector installed flue pipe of the bag dust catcher can make further efforts to adsorb dioxins. Control on Heavy Metal in Exhaust Gases a. To carry out proper source control and classify and collect the waste. b. To apply the ejecting activated-carbon adsorption effect to remove heavy metal. Take mercury as an example, the activated carbon is injected into the upper reaches of the flue pipe of the bag deduster and remove mercury through absorption effect with the efficiency of about 90%. According to foreign data, the technical integration of semi-dry neutralizing tower and the bag dust catcher can achieve an optimal efficiency up to 99% in the foreign practical test. Fumes Purification System It is planned to apply the tandem semi-dry neutralizing tower and bag dust catcher for the flue-gas purification work. The hydrated lime slurry is ejected into the dry-absorption tower from the bottom upwards or from the top downwards to reduce the temperature of gases and neutralize the acidic gases. By ejecting activated carbon, the adsorption of dioxins and heavy metals is achieved, and then these materials enter the bag dust catcher, which will arrest the fine dust particles, neutralizer and particles generated by de-acidification reaction and particles adsorbed
