1.1 Project background In the past 4 decades, remarkable achievements have been made in the Chinese economic development. Yet the rapid economic development poses serious challenges to the environmental sustainability. At present, more than 400 million tons of solid waste is produced in Chinese urban areas every year, of which about 12 percent is plastic waste. Plastic pollution is also caused by microplastics found in the compost produced by urban kitchen waste treatment plants and plastics in bulky and construction waste. China has the world’s largest agricultural area under plastic films that are not universally collected, contributing substantially to plastic pollution of soils and subsequent plastics run off into the marine environment. China has become a major source of marine plastic waste in the world. In response to this severe challenge, the Chinese government attaches great importance to the prevention and control of solid waste and plastic waste pollution. The management of solid waste and plastic waste is in a rapid upgrading process aiming for reduction in amount, recycling as resource and proper treatment. With its improving policy, planning, regulatory mechanism, information management, infrastructure and institutional capabilities, China plans to cooperate with the World Bank for the implementation of China Plastic Waste Reduction Project (P174267). The Project aims to strengthen policy and institutional capacities of plastic waste management at the national and local levels and to reduce the pollution of municipal solid waste. The Project comprises 3 subprojects: (1) Support on policy and institutional capacity strengthening at the national level; (2) Technical assistance and institutional capacity building at the provincial, municipal and local levels; (3) Demonstration of solid waste and plastic pollution reduction, recycling and proper treatment in selected provinces and cities. Addressing plastic pollution and management requires a multisectoral effort, through upstream analytical and policy work on plastics, and improvements to the solid waste management sector, river water quality through programmatic cleaning efforts, and the plastic applications and handling in agriculture. In addition to this project focused on upstream policy and analytical support and solid waste management investments in two provinces, the World Bank is currently preparing two separate investment operations linked to river basins and the agricultural sector that include attention to Page 1 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project marine plastics: (i) China: Yangtze River Revitalization Program which among other areas will also address the challenges of marine plastics flowing into China’s longest rivers; and (ii) China: Food Safety and Plastic Reduction which will among others also focus on plastic food packaging. An ongoing technical assistance funded by the ProBlue Multi Donor Trust Fund is looking into contributing sources of plastic pollution, river transmission mechanisms and will offer benchmarking of plastic waste management mechanisms with those internationally. In Subproject 3, two cities are selected for the demonstration of solid waste and plastic pollution management. As one of the selected demonstration cities, Chongqing plans to implement the “Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Projectâ€?. The Project follows a framework approach for investments. Most urban activities have been identified (first batch of investments which is the subject of this EIA) while the specific rural activities will be identified during implementation (second batch of investments, which are covered in a preliminary EMSF under separate cover). Urban activities build upon the current system in Chongqing. Rural activities will feed into and link to the urban system such that complementarity is achieved along with efficiency and economies of scale. To that end, rural activities will be designed at a later stage, including related environmental impact and social assessments. The first-batch subprojects of the Chongqing Sub-Project include three subproject types and five subprojects which will be implemented in the first year of the project implementation: 1) Jiguanshi ship waste receiving and treatment project, 2) Luoqi low-value recyclable utilization base project, 3) Upgrading projects of Jieshi, Xiajiaba and Zouma Waste Transfer Stations. The specific service areas include Yuzhong District, Jiangbei District, Nan’an District, Jiulongpo District, Shapingba District, Dadukou District, Beibei District, Yubei District, Banan District and Bishan District of Chongqing. 1.2 Project description 1.2.1 Project objective The Project is designed to build an urban-rural plastic waste collection and transportation system, an efficient plastic waste resource utilization system, a sustainable policy system and a replicable plastic waste management model for Page 2 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project reference based on the principles of "reduction, recycling and proper treatment". It is estimated that, by 2022, when the first batch subprojects under the Project will be completed, the level of waste recycling in the main urban districts will be effectively promoted. With the transformation of the waste transfer stations in the first batch of subprojects and the construction of Luoqi low-value recyclable utilization base, the plastics recycling, utilization and reuse industry system will take initial shape with the coverage rate of mandatory classification of domestic waste reaches 70% and the plastics recycling, utilization and reuse rate gets 30%. As the completion of Jiguanshi ship waste receiving and treatment project, the water environment of the Yangtze River can be improved significantly. 1.2.2 Project investment and source The Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Project with loans from the World Bank has a total investment of about RMB 5,052.78 million. The project funds consist of two parts: self-raised by the enterprise and loan from the World Bank, not involving any loans from other multilateral or bilateral financial institutions. 1.2.3 Project content Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Project’s first-batch subprojects include 5 subprojects classified as 3 types: 1) Jiguanshi ship waste receiving and treatment project; 2) Luoqi low-value recyclable utilization base project; 3) Upgrading projects of Jieshi, Xiajiaba and Zouma Waste Transfer Stations.

D Supporting construction Manufacturing management building, maintenance workshop and warehouse for chemical storage will be built in Luoqi low-value recyclable utilization base. In addition, a 35-meter-high chimney will be built for gas emission. â‘¢Processes A, Waste plastics recycling process The waste plastics recycling facilities are equipped with two recycling processes which are waste plastics granulating process and waste plastics chemical cracking process. The waste plastics granulating process has a waste plastics cleaning line and a waste plastics granulating line (as the figure 1.2-4 below shows). 1) The waste plastic bags enter the unpacking unit for unpacking. 2) The waste plastics are transferred into the crushing unit by a conveyor, and the shredder and crusher crush the waste plastics with water. 3) The waste plastic fragments are introduced into the cleaning unit, and cleaned and dehydrated by the cleaning and dewatering machine. 4) After cleaning and dehydrating, the plastic fragments enter the granulator stably through the conveyor, and the molten strip plastic was extruded by the extrusion process. 5) The molten strip plastic is cooled by a circulating cooling water tank, and then cut into cylindrical particles by the granulator in a wet state. Figure 1.2-4 Waste plastics granulating process The waste plastics oilation and cracking process mainly consists of raw material pretreatment system, catalytic cracking system, catalytic reforming system, slag discharge system and condensation system (as the figure 12.-5 below shows). 1) PE, PP and PS of raw materials are selected and the impurity content is controlled. 2) Under the action of cracking catalyst, the mixed waste plastics rapidly crack, and eventually generate gas (high-temperature gaseous oil) and powdered carbon slag. 3) Page 12 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The high-temperature gaseous oil purified by dedusting contain a large amount of unsaturated hydrocarbons. In the catalytic reforming unit, the unsaturated hydrocarbon components are reformed under the action of the reforming catalyst. 4) The high temperature gaseous oil pass through the condensation system to get oil- water mixed liquid, and the oil-water mixed liquid is separated into liquid oil and oily sewage by oil-water separator. Figure 1.2-5 Waste plastics chemical cracking process B, Waste glass recycling processes The waste glass recycling process is mainly composed of crushing process, mixing process, high-temperature calcinating process and cooling process. 1) The waste glass is crushed, drained, dried and finely crushed into 200~250 mesh glass powder. 2) Auxiliary materials (aluminum oxide, marble powder, quicklime) are added into the mixing pot and mixed evenly. 3) The evenly mixed glass waste including auxiliary materials is put into the high-temperature calciner and calcined at 900°C. 4) After cooling, crushing and screening, glass pumice is finally obtained. Figure 1.2-6 Waste glass recycling process Page 13 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project C, Waste textiles recycling process Waste polyester clothing and leftover material are used as raw materials. The metals and buttons are removed manually, and the moisture content is properly reduced before crushing. Then the crushed raw materials are melted and sent by the conveyor to the alcoholysis cauldron with mechanical stirring device. At the same time, a stoichiometric quantity of ethylene glycol (EG) is added into alcoholysis cauldron. With the temperature of the alcoholysis cauldron keeping at 200-260°C, the raw materials will be held in the alcoholysis cauldron for 30-90min. Then the raw material will be hydrolyzed and depolymerized with ethylene glycol, so to obtain its filtrate through filtration, and then ethylene glycol will be recovered. As the next step, an appropriate amount of methanol will be added into the filtrate for trans-esterification reaction, and dimethyl terephthalate (DMT) will be precipitated by cooling crystallization. Following the recrystallization, centrifugation and distillation, the refined DMT with a purity of above 99.99% can be obtained. As a result, PET will be prepared by trans-esterification of DMT with ethylene glycol and BHET polymerization, and then it will be sliced and spun.

The compactor vertically compacts the waste in the container until the container is fully loaded. Then the traction mechanism takes the container out of the berth and pull it on the transfer vehicle horizontally. At last, the transfer vehicle transports the container to the waste treatment plant. The process is displayed in the figure below. Figure 1.2-11 Vertical waste compression process B, Kitchen waste sorting process The kitchen waste is directly poured into the receiving trough and transported to the bag-breaking screening drum through the chain-plate feeder and the lifting-belt conveyor. After the kitchen waste enters the bag-breaking screening machine, the bag breaking knife evenly distributed in the screening drum cuts the waste bag, so that the kitchen waste can be fully graded by particle size in the rotating screening drum. The diameter of the sieve mesh of the drum bag-breaking screening machine is 80 millimeters. The screened waste are classified into two categories: the waste undersize of 80 millimeters and oversize of 80 millimeters. The kitchen waste undersize of 80 millimeters, mainly composed of soil and organic kitchen residues, passes through the sieve mesh. The kitchen waste undersize of 80 millimeters is transported back to the domestic waste discharge tank through the conveyor belt and then into the compression system. The kitchen waste oversize of 80 millimeters contains a relatively large amount of recyclable materials which will enter the winnowing machine through the belt of conveyor. After winnowing, the oversize kitchen waste falls into different conveyor belts and enters the corresponding collection containers respectively, and then enters the photoelectric separation workshop through the conveyor belt for further sorting. The process is shown in the Page 24 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project figure below. Figure 1.2-12 Kitchen waste sorting process C, Recyclable waste sorting process Waste plastics sorting process: The waste plastics sorting process is mainly relied on photoelectric sorting equipment, and also using intelligent robots as supplementary means. The waste plastics are poured into the sorting line and transported by the plate-chain conveyor to the puncture machine and the label remover. The plastic bottles are punctured and flattened, and their labels are removed. Then, the waste plastics are evenly sent to the photoelectric sorting machine through the shaking feeder. The transparent PET bottles, variegated PET bottles, transparent HDPE bottles, varicolored HDPE bottles and junk is sorted. The recyclable plastic bottles after classification are sent to the associated baler through the conveyor. Intelligent robots are arranged to assist in sorting waste plastics to improve the screening efficiency. Junk is collected, packed and then disposed separately. The waste plastics sorting process is displayed in the figure below. Page 25 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.2-13 Waste plastics sorting process Waste paper sorting process: The waste is manually unpacked and loaded. The more pure waste paper is put into the conveyor and directly packed, and the others are put into the receiving trough. Coarse sorting is performed by OCC. The small-sized and soft miscellaneous paper enters the temporary storage line as the sieve residue, and the large-sized and hard paper boards are discharged as the screen residue, and enter the corresponding manual sorting line. The paper boards after manually sorting out the miscellaneous paper are sent to the packer for packing; miscellaneous paper as the screen residue is discharged to a separate manual sorting line, and the books and newspapers with high recycling value are manually selected and packed. The waste paper sorting process is shown in the figure below. Page 26 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.2-14 Waste paper sorting process Waste metals sorting process: The waste are manually unpacked and loaded. Firstly, large waste is put into the metal shearing equipment for shearing. The more pure metals are put into the conveyor and directly packed, and the others are put into the receiving trough. the small household appliances are sorting manually, and iron metals are sorted out by the iron remover. Then, non-ferrous metals such as aluminum and copper are sorted out by eddy current. Fnally, the sorted metals are sent to the metal packer for packing. The figure 1.2-15 shows the waste metals sorting process. Figure 1.2-15 Waste metals sorting process Waste glass sorting process: According to the investigation of downstream manufacturers, the recyclable glass is mainly classified into colorless glass and colored Page 27 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project glass, which can be selected out during the preliminary sorting at the front transfer station. In the subprojects, only the recyclable glass is crushed after manual impurities removal, and the crushed recyclable glass is transported to the glass storage area by the transfer machine. Waste textiles sorting process: In the subprojects, the waste textiles are sorted manually, and the waste textiles with poor appearance are transported outward after being packed and compressed. The waste textiles with better appearance are temporarily stored, and then transported outward after a certain amount of accumulation. 1.3 Applicable laws, regulations and the Word Bank ESF standards The relevant domestic laws, regulations, policies and standards which are applicable to the first-batch subprojects proposed, as well as the applicable World Bank’s Environmental and Social Framework (ESF) and Environment, Health and Safety Guidelines (EHSGs) are listed as below: 1.3.1 Relevant domestic laws, regulations and policies Based on ‘Regulations on approval procedures for environmental impact assessment of construction projects of State Environmental Protection Administration ’ (Order No. 29 of State Environmental Protection Administration), the construction unit shall prepare environmental impact assessment report and environmental impact assessment report form for the first-batch subprojects according to the stipulation of ‘Classified management directory of environmental protection for construction projects’, then submit to the local ecology and environment bureau where the project is located for approval.

Subprojects with low, medium and significant risk level shall be approved by the environmental and social business department of the World Bank; subprojects with high risk level shall be submitted to RSA of the World Bank for approval after being reviewed by two Business Bureaus of the World Bank.. According to ESF’s requirements of the World Bank, the project team should identify, evaluate and mitigate the risks and impacts of project implementation on the environment and society. Eight environmental and social standards (except ess7 and ess9) are applicable to the whole life cycle of the project. Detailed information is shown in the table below. Page 33 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Table 1.3-3 Analysis on Applicability of Environmental and Social Standards of the World Bank No ESS Applicability Description . The first batch of projects only includes facilities construction activities. Infrastructure construction subprojects cover the collection, classification, transportation and utilization/processing facilities for domestic waste as well as the collection and transportation facilities for ship waste and floating waste. Potential negative environmental impacts are composed of dust, noise, waste water, soil erosion, traffic interference and common garbage in the construction stage, as well as impacts on community health & safety, occupational health & safety, and aquatic organisms. The main environmental and social risks and impacts of the project come from the operation of the facilities: such ESS1: as odor and sewage in the operation period of Waste Assessment Transfer Stations, temporary storage and and transportatiom of hazardous household waste, and Management the production, storage and transport of hazardous 1 of Yes substances involved in Luoqi low-value recyclable Environmenta utilization base. These matters will have serious l and Social impacts on environment, community health and Risks and safety as well as occupational health and safety. Thus, Impacts the environmental risk is Substantial. However, these impacts can be effectively managed and controlled by good industrial design and operation. The first-batch subprojects do not involve associated facilities, but will involve some ancillary facilities, such as waste transfer and disposal facilities. In the Environment Impact Assessment Report, identification and due diligence review were conducted for these ancillary facilities. Environmental Impact Assessment Report (including Environmental and Social Management Plan), Stakeholder Engagement Plan (SEP) and Environmental and Social Commitment Plan (ESCP) were prepared. ESS2: Labor The works involved in the first-batch subprojects and Working Yes include direct workers and contracted workers, but 2 Conditions do not include the community workers and primary supplier workers in the implementation process. Page 34 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project No ESS Applicability Description . Hence, the requirements of the standard concerning working conditions, workers' rights, grievance mechanism, as well as occupational health and safety are applicable to the Project2. Occupational health and safety risks and impacts primarily arise in the construction and operation stages of the Project, including traffic safety, mechanical injury and falling in the construction period of various subprojects; work involving high temperature and drowning during the operation of Jiguanshi ship waste receiving and treatment project; traffic safety, disease and falling during the operation of the transfer station,as well as production, storage and transportation of hazardous and chemical materials, mechanical injury and work involving high temperature during the operation of Luoqi low- value recyclable utilization base. For the direct workers and contract workers involved in the first-batch subprojects, a Labor Management Procedure (LMP) has been prepared in the SIA document. The first-batch subprojects contain processing activities of recyclable waste, involving water and energy consumption. The clean production principle is adopted in the processing section. With small water consumption, the Project is not located in an area vulnerable to the shortage of water resource and ESS3: water supply, so the impact on local water use and Resource water resources can be ignored. Efficiency and Pollution Yes Infrastructure construction subprojects will generate 3 Prevention waste water, waste gas, solid waste and noise and pollution in the construction and operation. The Management Waste Transfer Stations involve storage and transportation of hazardous household waste. Luoqi low-value recyclable utilization base involves the production, storage and transportation of chemical and hazardous substances. The first-batch subprojects do not involve landfill, waste incineration, biogas production by anaerobic digestion and coal fired boiler, so they are not main 2 Please check the ‘Environmental Sanitation Group’ s Labor Management Procedure (LMP) for the first-batch subprojects’ in Annex 2 of the SIA for the first-batch subprojects of Chongqing Project for the detailed analysis and investigation on ESS2.

According to the ESF and EHSGs of the World Bank, as well as relevant Good International Industry Practice (GIIP), resource efficiency control and pollution management were evaluated and mitigation measures were proposed in the Environmental Impact Assessment. The first-batch subprojects may generate health and safety impacts on the communities surrounding the Project sites in the implementation process. In the construction process of facilities, the increase of transport vehicles and each construction camp (40 workers in the peak construction period) will cause risks and impacts on local community health and safety, such as spread of COVID 19 and other infectious diseases. During temporary storage and transport of hazardous household waste as well as the use, production, storage and transport of ESS4: chemical and hazardous materials (including Community gasoline and diesel products), risks and impacts will 4 Yes Health and be caused on community health and safety. Safety In the environmental impact assessment process, the available routes for hazardous materials and waste transportation were compared and selected. The materials and waste generated in various subprojects will be directly transported via the highway so to avoid health and safety risks and impacts to the communities. The construction camp management plan, traffic management plan, and emergency response plan were prepared in the environmental impact assessment. ESS5 aims to avoid or minimize involuntary ESS5: Land resettlement, prevent forced eviction, and mitigate Acquisition, the inevitable and adverse impacts on society and Restrictions economy by a series of methods, which are brought on Land Use by land acquisition or restrictions on land use.. 5 and Yes According to the current identification, the first- Involuntary batch subprojects have completed land acquisition Resettlement and demolition at the time of project identification, and no new land acquisition and demolition is involved temporarily, so there is no need to prepare Page 36 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project No ESS Applicability Description . RAP. However, due diligence3 is still necessary, so to figure out the situation of land acquisition and demolition and whether there are any remaining problems. The 5 subprojects are located in the built-up urban areas not involving natural habitats, but modified habitat in Jiguanshi river section of the Yangtze River. Due to overfishing and construction of upstream and downstream hydropower/dam, the main ecological function of this river section has been significantly degraded, and the original local fishes are replaced by commercial fishes released artificially, such as carp and crucian. The first-batch subprojects contain the construction of Jiguanshi ship waste receiving and treatment ESS6: project, and the ships receiving its service and the Biodiversity ships for floating waste collection operate in the Conservation Chongqing section of the Yangtze River. Thus, the and operation process of Jiguanshi ship waste receiving 6 Sustainable Yes and treatment project does not involve alien species Management risk brought by ballasts. of Biology The construction process of Jiguanshi ship waste Natural receiving and treatment project involves dock basin Resources excavation, which will affect the water quality. But, the range of such impacts is very small, and the impacts will disappear immediately after the completion of the construction. So during the operation period, there will be slight impact on the water body. On the contrary, the project will reduce the pollution of the river section by collecting ship sewage and garbage as well as floating waste. The first batch subprojects exclude introducing any invasive alien species, primary production and harvesting of living natural resources. ESS7: Ethnic The 5 subprojects are located in the central urban 7 minority No area. During the preparation of the project, the SIA people/Sub- unit conducted a detailed screening of social risks Saharan and impacts of the project4. The first batch of five sub 3 Please check the ‘Social Audit report on the first-batch subprojects of Chongqing Urban-Rural Integrated Plastic Waste Management Project’ for the social investigation results of ESS5. 4 Please check the ‘Social Audit report on the first-batch subprojects of Chongqing Urban-Rural Page 37 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project No ESS Applicability Description . African project sites were not located in ethnic minority Historically communities, and there was no collective attachment Underserved of ethnic minority communities to the proposed Traditional project area. Therefore, ESS7 is not applicable. Local Communities The first-batch subprojects do not involve cultural heritage with important cultural significance for the ESS8: Cultural 8 Yes local community or the cultural heritage protected by Heritage laws. But, the accidental discovery procedure is included in the environmental management plan. ESS9: Financial The Project does not involve FI, so the standard is not 9 No Intermediary applicable.

(1) Atmospheric environment According to Technical guidelines for environmental impact assessment: Atmospheric environment (HJ 2.2-2018), the classification method of assessment work is as follows: Get the project’s main pollutant ratio of maximum surface air mass concentration to standard Pi (‘i’ indicates the i-th pollutant, and the ratio is described as ‘Max concentration ratio to standard’ for short); when Pmax＜1%, the assessment level is 3; when 1% ≤ Pmax ＜ 10%, the assessment level is 2; and when Pmax ≥ 10%, the assessment level is 1. According to calculation, only Jiguanshi ship waste receiving and treatment subproject’s Pmax＜1% (assessment level 3), and the other subprojects are all 1%≤Pmax＜10% (assessment level 2). According to the Guideline, the side length of the atmospheric environmental impact assessment scope of level II assessment project is 5 km, and the atmospheric environmental impact assessment scope of level III assessment project does not need to set assessment scope. (2) Surface water environment According to Technical guidelines for environmental impact assessment: Surface water environment (HJ 2.3-2018), the construction project with water pollution is classified by the waste water discharge mode and amount. The construction projects with direct waste water discharge mode are classified as Grade 1, Grade 2 and Grade 3A according to the discharge amount of waste water and pollution equivalent number of water pollutants. The construction projects with indirect discharge mode are classified as Grade 3B, therefore the 5 subprojects are all Grade 3B. Among the subprojects, only Jiguanshi ship waste receiving and treatment project involves water related construction, based on the Guideline, the surface water environment assessment scope is from 500m at the upstream of the proposed dock site to 500m at the downstream. (3) Groundwater environment Page 65 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project According to Technical guidelines for environmental impact assessment: Groundwater environment (HJ 610-2016), the assessment level is determined according to the industry classification of construction project and the groundwater environmental sensitivity level, which can be divided into the level 1, 2 and 3. The 5 subprojects’ groundwater environment impact assessment categories are determined according to Annex A, and just Luoqi low-value recyclable utilization base project requires groundwater environment assessment. As the groundwater environmental sensitivity is ‘insensitive’, the assessment work is level 3. According to the Guidelines, the assessment scope is the hydro-geological unit of the project site. (4) Acoustic environment According to Technical guidelines for environmental impact assessment: Acoustic environment (HJ 2.4—2009), if the acoustic environment function zone of the construction project is Category 1 or Category 2 area specified in GB 3096, or the noise level of sensitive targets within the assessment scope before and after the construction period of the project increases by 3-5 dB (a) [including 5 dB (a)], or the number of people affected by the noise increases greatly, it shall be assessed as level 2. The 5 subprojects’ sites are in Category 2 acoustic function zones, according to prediction, the noise level of sensitive targets within the assessment scopes before and after the construction period of the subprojects increase within 3 dB (a), and no increased population under the noise impact, therefore, the 5 subprojects shall all be assessed as level 2. According to the Guidelines, the assessment scope is the range of 200m out of the site boundary. (5) Ecological environment Based on Technical guidelines for environmental impact assessment: Ecological impact (HJ 19-2011), according to the ecological sensitivity of the affected area and the scope of land (including water area) occupied by the project, including permanent land and temporary land, the ecological impact assessment work is divided into level 1, level 2 and level 3. The 5 subprojects’ affected areas do not involve special ecological sensitive area or important ecological sensitive area, which are ordinary regions with land occupation area ＜2km2, therefore, the assessment level is level 3. Page 66 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project According to the Guideline, the terrestrial ecological scope is the range of 500m outside the factory boundary; the aquatic ecological scope is from 500m upstream to 500m downstream of the proposed dock along the river; and the transverse scope is about the range of 100m from the river bank to the nearshore boundary of Jiguanshi anchorage. (6) Soil environment Based on Technical guidelines for environmental impact assessment: Soil environment (Trial) (HJ 964—2018), the soil environmental impact assessment is divided as level 1, level 2 and level 3. According to the annex A of the Guidelines, among the 5 subprojects, only Luoqi low-value recyclable utilization base project is a Category 3 project which requires soil environmental impact assessment work. The land occupied by the base is medium-sized, and the soil environmental sensitivity is sensitive (there is arable land around the project). Therefore, according to the soil environmental impact assessment project category, land occupation scale and sensitivity, the assessment work is classified as level 3. As for Jiguanshi ship waste receiving and treatment project, due to its site close to Xiayaogou Anchorage, in order to correctly judge the anchorage’s impact on the proposed dock site, it is necessary to conduct level 3 soil environment assessment. According to the Guidelines, those subprojects mentioned above are all polluting projects, and their assessment scopes are the range of 50m out of the site boundary (7) Environmental risk Based on Technical guidelines for construction project environmental risk assessment (HJ 169—2018), according to the hazards of the materials and process systems involved in the construction project and the environmental sensitivity of the place where the project located, combined with the environmental impact approach under the accident situation, the potential environmental hazards of the construction project can be generalized and analyzed, and then the environmental risk potential can be determined according to the Table 2. The risk potential of construction project is classified as rating I, II, III, IV and IV+. Among the subprojects, only Luoqi low-value recyclable utilization base project requires environmental risk assessment, and its environmental risk assessment requires brief analysis as its risk potential is rating I.

As the results of caoculation, among the 5 subprojects, besidesJiguanshi ship waste receiving and treatment project’s Pmax < 1% (Grade III), the rest 4 subprojects’ Pmax values are all between 1% and 10% (Grade II). 16 According to ‘Technical guidelines for Environmental Impact Assessment : Surface water Environment’ (HJ 2.3-2018), the assessment grade of construction project with water pollution is classified with its wastewater discharge mode and amount. The construction project with direct discharge of wastewater is divided as Grade I, Grade II and Grade IIIA according to the wastewater discharge amount and the pollution equivalent of water pollutant; the project with indirect discharge of wastewater is classified as Grade IIIB. Therefore, all the 5 subprojects are Grade IIIB.

After corresponding measures are taken, the acoustic environmental qualities of them can all meet the standard. There are no atmospheric, surface water and soil environment protection targets. Among the subprojects, Jiguanshi ship waste receiving and treatment project involves no environment protection target; Luoqi low-value recyclable utilization base project has 1 environment protection target which is away from the site boundary by 200m; Jieshi waste secondary transfer station upgrading project has 3 environment protection targets, with distances away from the site boundary of 175m, 230m and 300m respectively; Xiajiaba waste secondary transfer station upgrading project involves 2 environment protection targets which are respectively away from its boundary by 100m and 120m; and Zouma waste secondary transfer station upgrading project has 4 environment protection targets, whose distances between the project site boundary are 85m, 130m, 150m and 300m. 1.4 Baseline Data 1.4.1 Natural environment status (1) Geographic location Chongqing is a provincial-level administrative region and the only municipality directly under the central government in central and western China. Chongqing is located in southwest China, and in the upper reaches of the Yangtze River, across 105°11'~110°11'E and 28°10'~32°13'N. Covering a total area of 82,400km2, it has jurisdiction over 26 districts, 8 counties and 4 autonomous counties. The service scope of the five subprojects includes Chongqing central urban area (the 9 districts of the downtown area) and surrounding small and medium-sized towns (Bishan District). (2) Weather and climate Located in the East Asian monsoon region in the east of the Qinghai-Tibet Plateau, Chongqing enjoys a subtropical humid monsoon climate with four distinct seasons, Page 73 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project abundant rainfall with uneven distribution in time and space, sufficient heat and long frost-free season, very hot summer, obvious vertical change of temperature, and many foggy days of one year in the city. Chongqing belongs to the low value area of sunshine in China, with complex and changeable weather and frequent meteorological disasters Hilly and valley areas are characterized by no severe cold winter, very hot summer, frequent summer drought, and foggy autumn and winter. (3) Landform and topography Chongqing is located in the transition zone between the Qinghai-Tibet Plateau and the middle and lower Yangtze Delta Plain, with large topographic relief. Its terrain slopes progressively downward from south to north along the Yangtze River Valley. As its northwest and central parts are dominated by hills and low mountains, and its southeast part adjoins the Daba Mountain and Wuling Mountain ranges, with many slopes, so Chongqing is widely known as the "Mountain City". The service scope of the Project areas includes the downtown area (the 9 districts of the central urban region) and surrounding small and medium-sized towns (Bishan District). With less relief, the central urban area and the Bishan District are mostly low hills and flat dams, at an altitude of below 900m. Refer to Figure1.4-1 for the topographic relief map within the Project location and service scope. Page 74 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.4-1 Topographic Relief Map within Project Location and Service Scope (4) Geology The vast majority of Chongqing Municipality belongs to the first-order tectonic units of Yangtze Paraplatform, and the few parts belong to the Qinling geosynclinal folded system. There are four secondary tectonic units in the area: Sichuan platform depression, Upper Yangtze platform depression, Longmen Mountain - Daba Mountain marginal depression and miogeosynclinal fold system of northern Daba Mountain. The tertiary tectonic units involved in the area are: part of Eastern Sichuan depression-folding bundle and Central Sichuan anteklise; Southeast Sichuan depression-folding bundle; Daba Mountain depression-folding bundle; and part of the southern margin of the miogeosynclinal fold system of northern Daba Mountain. According to the regional geological condition, Chongqing is not located in the seismic zone or in the earthquake-prone area. Refer to Figure 1.4-2 for the structural outline within the Project location and service scope. Page 75 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.4-2 Structural Outline within Project Location and Service Scope (5) Hydrological system The rivers in the administrative region of Chongqing belong to the Yangtze River basin, in a flow pattern of grid or arborization, with large surface runoff. The surface water resources are abundant but difficult for utilization. The trunk stream of the Yangtze River runs from southwest to northeast across the whole territory, with five main tributaries with south-north runoff direction as Jialing River, Qujiang River, Fujiang River, Wujiang River and Daning River and other hundreds of medium or small rivers, to form a radial and asymmetric reticulate water system. There are 374 rivers with a catchment area of more than 50km, 167 rivers with a catchment area of 50~100km, 152 rivers with a catchment area of 100~500km, 19 rivers with a catchment area of 500~1,000km, 18 rivers with a catchment area of 1,000~3,000km and 18 rivers with a catchment area of more than 3,000km. Surface water accounts for the majority of the total water resources in Chongqing, among which the average annual surface water generated by rainfall is about 56.77 billion cubic meters, and the average annual inflow from the Yangtze River, Page 76 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Jialing River and Wujiang River into Chongqing is about 383.9 billion cubic meters. According to Chongqing Water Resources Bulletin (2019) issued by Chongqing Water Resources Bureau in June 2020, in 2019, the whole city had a total water supply of 7.64719 billion cubic meters, per capita comprehensive water consumption of 245m3, and the water consumption per RMB 10,000 yuan of GDP (price of the year) is 32m3. The water consumption per RMB 10,000 yuan of industrial added value (price of the year) is 42m3, and the per capita daily water consumption of residents is 140L; the per capita daily water consumption of urban public is 78L, and the average water consumption of farmland irrigation per mu is 325m3. Chongqing is rich in water resources and water supply, which is not located in the water shortage area.Refer to Figure 1.4-3 for the drainage map within the Project location and service scope. Figure 1.4-3 The Project Location and the river system within the Service Scope 1.4.2 Current situation of ecological environment Page 77 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (1) Soil There are various soil types in Chongqing, and the zonal soil is yellow soil. In addition, there are many soil types in Chongqing. The project site and service scope mainly include paddy soil, alluvial soil, purple soil, yellow brown soil, yellow soil and other soil types. (2) Soil erosion Soil erosion of different intensities is found in Chongqing, but mainly in moderate and lower soil erosion areas, with obvious regional differences. Within the project area, the total soil erosion area of the central urban area and Bishan District is less distributed and of low intensity. The soil erosion area of Yuzhong District, Jiangbei District, Shapingba District, Nan’an District and Banan District accounts for about 25% of the total area, so the project area is not located in the area with serious soil erosion. Refer to Figure 1.4-4 for the soil erosion within project location and service scope. Page 78 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.4-4 The Project Location and Soil Erosion within the Service Scope (3) Terrestrial ecosystem Chongqing is diversified in ecosystems, rich in species and complex in structure. The ecosystems in Chongqing mainly include six Grade I ecosystems and more than 20 Grade II ecosystems, such as mountain forest ecosystem, grassland ecosystem, aquatic ecosystem, agricultural complex ecosystem, village/town ecosystem and urban ecosystem. The five subprojects mainly serve the central urban area and the surrounding small and medium-sized towns (Bishan District). After a long period of human development, the ecosystem of this area is mainly composed of urban ecosystem and agricultural complex ecosystem. However, there are still some important ecological sensitive points in the project area, such as nature reserves, forest parks, scenic spots and geoparks. At present, these important ecological sensitive points are identified and marked in Figure1.4-5. According to the overlay analysis, the five subproject sites do not involve the ecological sensitive areas and ecological protection red lines, nor the natural habitats and critical habitats. Page 79 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.4-5 Location Relationship between Ecological Sensitive Area in the Project Area and Project Site According to the site survey, the project-affected area primarily involves the urban and rural staggered area in which urban artificial ecosystem and agricultural ecosystem coexist and there is no natural habitat or critical habitat due to severe disturbance of human activities. In the project-affected area, the common vegetation primarily includes common arbor and scrub-grassland, which are locally common species, without rare or protected plants or ancient trees and rare trees. There may be a small number of amphibians, birds, rodents and reptiles in the project-affected area, and they are locally common species. Besides, there are no rare or protected animals in the project-affected area. (4) Aquatic ecosystem In the subprojects, only the Jiguanshi ship waste receiving and treatment project will involve water construction and operation. Therefore, this assessment mainly focuses on the investigation and analysis of the aquatic ecological status of this subproject. The river section where Jiguanshi ship waste receiving and treatment project locates is the Yangtze River’s Jiguanshi river section in Nan’an District of Chongqing, whose main economic function is shipping. According to survey, the dock’s location is away from the National Nature Reserve for Rare and Endemic Fish in the upper reaches of the Yangtze River18 about 55.1km in the upstream direction, and away from the Four Key Fish National Germplasm Resources Reserve 19 about 13.4km in the downstream direction. The ecological sessitive areas are far away from Jiguanshi ship waste receiving and treatment project site in both upstream and downstream directions and beyond the impact scope of Jiguanshi project. Within the assessment scope of Jiguanshi dock project, the 18 Notice on the issue of area, scope and functional zoning of the 28 national nature reserves, such as dahaiduo, Hebei Province.(MEP.letter [2013]No.161) 19 Area, scope and functional zoning of the second batch of National Germplasm resources protection zones (Announcement No. 1130 of the Ministry of Agriculture). Page 80 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project ecological sensitive areas such as fish spawning ground, feeding ground, wintering ground and migration channel are not involved. In this assessment, about the current situation of aquatic ecology within the aquatic ecological assessment scope of Jiguanshi dock, data collection, field investigation, interviews with fishermen and nearby residents, consultation with fish market, fishery experts and fishery departments were conducted. Data analysis was carried out, including water quality, zooplankton, benthos, fish resources, etc, and the ecological functions of the water area in the assessment scope were analyzed. For this assessment, 3 investigation sections were set within the aquatic ecological assessment scope to conduct investigation on the plankton. The investigation duration is February to April 2021. Figure 1.4-6 Positions of the investigation sample points Page 81 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 1.4-7 Field sampling A total of 55 phytoplankton species belonging to 6 phyla, 7 classes, 16 orders, 32 genera were collected in this survey. They were all common species in the area. The species belonging to Bacillariophyta and Chlorophyta were the most. There was no significant difference in the species composition of each sampling section. The biomass (wet weight) was 0.0855-0.1291mg/l. The density of algae cells is 3.88 × 104 ~ 5.04 × 104 cells / L, and the biomass of phytoplankton is very low. 27 species of zooplankton belonging to 18 genera and 3 phyla were collected in the assessment area. The most species were rotifers and protozoa. There was no obvious difference in the species composition of each sampling section. The average number of zooplankton is 5.22/l, the average biomass is 0.05774mg/l, and the biomass is very low. Within the assessment scope, there are 13 species of macrobenthos, which belong to 4 phyla, 5 classes, 8 orders, 10 families and 13 genera. They are all common species in the area. Arthropods are the most common species, followed by molluscs. The density and biomass of macrobenthos are low. The density ranged from 16 to 112 plants / m2, with an average of 64 plants / m2; the biomass ranged from 0.325 to 6.638g/m2, with an average of 4.20g/m2. Due to the total ban on fishing in the Yangtze River Basin, the fish resources investigation can not be carried out by fishing method. Therefore, the fish resources data of this assessment are analyzed by using the investigation in the nearby river section before the ban, the interviews of fishermen, fish markets and nearby residents, and the consultation results of fishery experts and fishery administration departments. According to interview and consuatation with the fishery administration departments, there are no fishing records or investigation records of rare and endemic fish within the aquatic ecological assessment scope Page 82 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project of the project within 10 years. From 2017 to 2019, among the 14 species of catch collected and recorded in the assessment river section, the dominant species are gobio and copperhead. All the 14 species are local common species, and there are no rare and protected fish. In recent years, the amount of fish resources has decreased significantly; the composition of fishery has also changed to some degree, that is, the number of small fish has increased, in addition, the main economic fish individuals are relatively small. The proposed construction site of Jiguanshi dock is located in Chongqing’s downtown area, with its main economic function as shipping and without key ecological functions. After the construction of water conservancy and hydropower projects, the hydrological conditions of water level, velocity, flow rate and water temperature of the river section have been completely modified, which has caused significant changes in habitat. The composition of plankton, benthos and fish were obviously changed, and the flagship species of the Yangtze River are "extremely endangered", some of which have been extinct in the wild. The riparian benthic fish originally distributed in this area moved up to the sections in upper reaches of the Yangtze River due to their unadaptability to the changes of hydrological conditions. Many times of artificial propagation and release of common local fish have been carried out in the Yangtze River Basin, which has changed the composition of fish community in the Yangtze River. On the other hand, the overfishing of fish by fishermen has resulted in a sharp decrease in the species and quantity of fish resources. Therefore, the aquatic ecological assessment scope is classified as a ‘modified habitat’. 1.4.3 Socioeconomic status (1) Basic demographic and economic conditions Chongqing Municipality governs 38 districts / counties, with a land area of 82,400 km2, in which the urban center occupies 4,800 km2, the medium, small towns, and rural areas occupy 77,600 km2, respectively. At the end of 2019, Chongqing had a resident population of 31.2432 million, and the urbanization rate is 66.8%. Chongqing has 4 ethnic minority autonomous counties and a district entitled to ethnic minority policies, namely, Shizhu County (minority population accounting for 79.3%), Pengshui County (53.85%), Youyang County (92.3%), Xiushan County (58.5%) and Qianjiang District (74.6%), which are all located in the southeast of Page 83 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Chongqing. The main ethnic minorities are Tujia and Miao. The 5 subprojects of the first-batch are implemented in the downtown area, which contains no concentrated ethnic minority residential areas. In 2019, Chongqing’s GDP reached 2.360577 trillion yuan, and per capita GDP per capita was75,828 yuan, ranking 9th among the 31 provinces / autonomous regions / municipalities in China.The per capita disposable income of residents in Chongqingwas 28,920 yuan, of which the number increased to 37939 yuan when considering the urban residents, ranking 11th in China, and that of rural residents was15,133 yuan, ranking 17th in China. (2) Overview of cultural relics in Chongqing By the end of 2019, Chongqing has 445 cultural sites protected at or above the municipal level, including 64 major cultural sites protected at the national level and 381 cultural sites protected at the municipal level. These cultural sites are located in the national or regional development control areas. According to the scene investigation, no tangible cultural heritage was found in the proposed construction site of the 5 subprojects. (3) Overview of endemic disease/epidemic disease occurrence in the project area Endemic diseases refer to the local and regional diseases which serious endanger the physical health of the general public. Endemic diseases in Chongqing mainly include endemic fluorine poisoning, iodine deficiency disorders and Keshan disease. Endemic fluorine poisoning is a kind of chronic systemic disease caused by long- term intake of excessive fluorine by local residents through drinking water, food and air, due to excessive fluorine in the local environment, which is mainly characterized by skeletal fluorosis and dental fluorosis. Iodine deficiency disorders are mainly caused by environmental iodine deficiency and insufficient iodine intake by human body, which are commonly found in mountainous areas far away from the coast and with a high altitude. Keshan disease is only found in low-selenium area. Now, no one infected by COVID-19 has been found in the communities around the first-batch subprojects, and there are good medical facilities around the Page 84 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project subprojects. 1.4.4 Current situation of solid waste management in the project area (1) Output and composition of domestic solid waste in Chongqing According to the Annual Report of Environmental Pollution Prevention and Control of Municipal Solid Waste in Large and Medium-sized Cities in 2019, the output of domestic waste produced by 200 large and medium-sized cities throughout the country in 2018 was 211,473,000 tons. Among them, the output of domestic waste in Chongqing ranked fourth (7.17 million tons), second only to Shanghai, Beijing and Guangzhou. The urban domestic waste collection and transportation system in Chongqing mainly consists of two parts: one part is responsible for collection and transportation of restaurant waste and the other part is responsible for collection and transportation of other domestic waste other than restaurant waste. The data from Chongqing municipal environmental sanitation monitoring center indicates that, among other domestic waste other than restaurant waste, recyclable waste such as plastic cement, paper, textile, wood and bamboo, glass and metal accounts for 41.21%, and plastic waste accounts for 14%; among restaurant waste, plastic waste accounts for 3%. The proportion of plastic waste in the total output of domestic waste in Chongqing is higher than the national average value (12%). (2) Current situation of main facilities of domestic waste The domestic waste classification in Chongqing is at the preliminary stage, plastic waste and domestic waste are mixed and collected by the same set of waste collection and transportation system, and the collection points of domestic waste are in the charge of each district, county, street and town respectively. As of 2018, in total 1023 waste collection points were established in all districts and countries in Chongqing, including 3,590,000 domestic waste containers and 47,000 kitchen waste containers; 726 waste transfer stations (including 3 classification transfer stations which have been put into use in the main urban area), 2565 domestic waste transfer trucks, and 3265 kitchen waste transfer trucks. In total 7 incineration plants have been put into use and 3 are under construction, 37 landfills have been put into use, 2 are under construction and 11 are out of service. In total 6 kitchen waste treatment plants have been put into use, Page 85 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 1 is under construction and 4 are under commissioning. There are 20~30 plastic waste collection enterprises. At the present stage, the harm-removal treatment methods of domestic waste in Chongqing mainly include incineration and landfill, accounting for about 54% and 45% respectively. At present, Chongqing is in shortage of facilities for waste classification transfer and transportation, and the waste sorting ability of transfer station needs to be improved urgently. Since there is a lack of sorting facilities for plastic waste and there is no independent resource utilization facility for plastic waste, some domestic waste is recycled by private enterprises, and the rest of plastic waste is transported to the domestic waste landfill for landfill and is finally leaked to the environment; The capacity of resource utilization and harm-removal treatment of domestic waste such as recyclable materials, kitchen waste and household hazardous waste is insufficient. 1.4.5 Environment audit (1) Waste Secondary Transfer Station From November 5 to 6, 2020, the environmental assessment consulting team conducted an environmental audit on the original waste secondary transfer stations. The environmental audit results of the original secondary transfer station are shown in table below. Table 1.4-1 Environmental audit results of the existing secondary transfer stations The existing waste Working units secondary Environmental impact and mitigation measures and processes transfer station Jieshi waste At present, the After pre-treated by the integrated sewage secondary domestic waste treatment facility, the waste water will be sent to transfer transfer Jieshi Group sewage treatment plant for further station workshop has treatment through the municipal pipe network, and already then discharged when its quality meets the relevant Page 86 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The existing waste Working units secondary Environmental impact and mitigation measures and processes transfer station established 12 standard. domestic waste Based on the on-site survey, it is found out that transfer units leachate leakage exists during the vehicle with horizontal transportation. waste compression At present, the leachate is transported to Heishizi process, and a sewage treatment plant for treatment.

The transfer station is equipped with 15 integrated deodorization-purification towers, which can provide a removal efficiency of particulate matter, non methane hydrocarbon and odor concentration by 90%. The plant boundary odor concentration can meet the requirements of Emission standard of odor pollutants (GB 14554-93) and cause an acceptable impact on the surrounding area.

The plant boundary odor concentration can meet the requirements of Emission standard of odor pollutants (GB 14554-93) and cause an acceptable impact on the surrounding area. The existing waste secondary transfer stations involved in this project as Jieshi, Page 88 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Zouma and Xijiaba have been completed and put into operation. They have already passed the environmental protection acceptance, with effective environmental protection measures. The existing comprehensive building, metering system, surrounding municipal roads, car washing area, etc are all reliable. It is necessary for Jieshi waste secondary transfer station and Zouma waste secondary transfer station to strengthen the management and maintenance against the situation of leachate leakage during the vehicle transportation. The leachate treatment capacity of Jieshi waste transfer station, xiajiaba waste transfer station and zoumaba waste transfer station is 450m3 /d, 180m3/d and 350m3/d respectively. Each waste transfer station is equipped with exhaust funnel and integrated deodorization purification tower. The current odor emission meets the standard, and the original odor treatment facilities have high removal efficiency. (2) Ancillary Facilities For the associated facilities of the Project, the identification of associated facilities and environment audit on the environmental and social risks and impacts caused by them shall be carried out according to the requirements of the World Bank in Environmental and Social Framework. Upon identification, the subprojects have no associated facilities, but has some ancillary facilities. In November 2020, the Environmental assessment consulting team conducted environmental auditing for the existing secondary transfer stations and the upstream primary transfer stations as well as the 9 ancillary facilities (Zouma Leyuan sewage treatment plant in Jiulongpo District, Jieshi Group sewage treatment plant in Ba’nan District, Chengbei sewage treatment plant in Yubei District, Jiguanshi sewage treatment plant, Luoqi Town No.2 sewage treatment plant in Yubei District, Luoqi waste incineration plant, Jiangjin Baiguoyuan waste incineration plant, Fengsheng waste incineration plant and Luoqi restaurant waste treatment plant). The audit conclusion is as below: (1) About the 5 sewage treatment plants involved in this project, namely Zouma Leyuan sewage treatment plant in Jiulongpo District of Chongqing City, Jieshi group sewage treatment plant in Ba’nan District, Chengbei sewage treatment plant in Yubei District, Jiguanshi sewage treatment plant in Nan’an District and Luoqi Town No.2 sewage treatment plant in Yubei District, they can reach the relevant pollutant discharge standards at current stage, with environmental Page 89 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project protection measures in place and surfficient treatment capacities capable to meet the sewage discharge demands of the 5 subrpojects of the Project. Therefore, they are reliable enough to be relied on. (2) About the waste incineration plants involved in the project, namely Jiangjin Baiguoyuan waste incineration plant and Fengsheng waste incineration plant, they can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place and surfficient treatment capacities capable to meet the disposal demands for other-type waste of the 3 waste secondary transfer stations. So, they are reliable enough to be relied on. As Luoqi waste incineration plant is in trail operation stage, there is no monitoring data for now. (3) As one of the units involved in the project, Luoqi restaurant waste treatment plant can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place. After the phase II expansion, its treatment capacity will fulfill the restaurant waste and kitchen waste treatment demands of the 3 waste secondary transfer stations, therefore the expanded Luoqi restaurant waste treatment plant can be relied on. (4) About the existing waste secondary transfer stations involved in the project, namely Jieshi waste secondary transfer station, Zouma waste secondary transfer station and Xiajiaba waste secondary transfer station, they all have passed environmental protection acceptances with environmental protection measures in place. Their existing comprehensive office building, metering system, surrounding municipal roads, car washing area, etc all can be relied on. The transport vehicles of Jieshi and Zouma Waste Secondary Transfer Stations have leachate leakage situations during transportation, which are required to strengthen the management and maintenance. The treatment scales of leachate regulating tanks are 450m3/d of Jieshi waste secondary transfer station, 180m3/d of Xiajiaba waste secondary transfer station and 350m3/d of Zouma waste secondary transfer station. Each transfer station equips with odor treatment facilities such as waste gas exhaust funnel and integrated deodorization and purification tower etc, and with the relatively large Page 90 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project treatment scale of the odor treatment facilities, the odor discharge can meet the relevant standards at current stage. (5) Those waste secondary transfer stations’ primary transfer stations are widely dietributed in Chongqing’s downtown area and medium-small sized towns/villages, with sufficient transfer capacity which is capable to meet the demands of the secondary transfer stations. As the sewage is treated by the integrated sewage treatment facility and then discharged after the quality meets the relevant standards, and the soild waste is treated and disposed of by the qualified units, therefore, they can be relied on. In summary, according to the environmental audit, the original existing waste secondary transfer stations and the upstream primary transfer stations as well as the 9 ancillary facilities can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place and sufficient treatment capacities basically capable of meeting the demands of this project. And, the feasibility of the project relying on the existing leachate regulating tanks and odor treatment facilities of the existing secondary transfer stations will be demonstrated in Chapter 5. 1.4.6 Current situation of regional environment quality of the subprojects (1) Current situation of ambient air quality â‘  Current situation of regional ambient air quality According to the data of Ecological Environment Bulletin of Chongqing in 2019 published by Chongqing Ecological Environment Bureau on June 3, 2020, the ambient air quality of the project site in Banan District, Nan’an District, Yubei District, Jiulongpo District are not up to the secondary standard limit value of Ambient Air Quality Standard (GB3095-2012), so they are not up-to-standard areas. This is mainly due to the fact that the four districts are all located in the main urban area, and the traffic pollution is relatively large, as well as due to the dust emission from the construction site of urban infrastructure construction and the industrial pollution emission of the industrial park in the urban area. In this regard, Chongqing has formulated the Implementation Plan of Chongqing Carrying Page 91 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project out the State Council's Three-year Action Plan to Win the Blue Sky Protection Campaign, for continuously improving the environment air quality. â‘¡ Environmental status monitoring of the project site Three monitoring points are provided at Jieshi Waste Transfer Station, Xiajiaba Waste Transfer Station and Zouma Waste Transfer Station, and the monitoring factors are H2S, NH3, and the results at point A1, A2, A3 meet the standards of Appendix D of (HJ2.2-2018). (2) Current situation of surface water environment quality According to the data of Ecological Environment Bulletin of Chongqing in 2019 published by Chongqing Ecological Environment Bureau on June 3, 2020, the subprojects are located in the Yangtze River Basin. The overall water quality of the trunk streamof Yangtze River in Chongqing is excellent, and the water quality of the monitoring section of the main stream reaches or is better than Grade III. (3) Current situation of groundwater environment quality This assessment has carried out groundwater monitoring for the subproject of Luoqi low-value recyclable utilization base. The monitoring factors are Cl-, SO42-, pH, ammonia nitrogen, permanganate index, total hardness, nitrate nitrogen, nitrite nitrogen, sulfate, chloride, volatile phenols, fluoride, cadmium, lead, mercury, dissolved solids, total coliform group. And the conclusion is, except for the value of total coliform group, the monitoring results of other indicators of the downstream points in the proposed project site reach Category III standard in (GB/T 14848-2017), and there is no project characteristic factor exceeding the standard. Combined with the field investigation, the over-standard of the total coliform group may be caused by the domestic sewage and agricultural sources from the surrounding residents in the project area. (4) Current situation of acoustic environment quality 10 acoustic environmental monitoring points are arranged at Jiguanshi ship waste receiving and treatment project, Jieshi Waste Transfer Station, Xiajiaba Waste Transfer Station, Zouma Waste Transfer Station and Luoqi low-value recyclable utilization base. And continuous monitoring was executed for two days, once in daytime and once in night of every day. And the conclusion is that the monitoring results of environmental noise at sites N1~N10 reach the limit of Grade II Page 92 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project functional area of Environmental Quality Standard for Noise (GB 3096-2008). (5) Current situation of soil environment quality Three surface points are arranged in Luoqi low-value recyclable utilization base and Jiguanshi ship waste receiving and treatment project respectively. And the monitoring factors are basic factors of GB36600, include arsenic, cadmium, chromium (hexavalent), copper, lead, mercury, nickel, carbon tetrachloride, chloroform, chloromethane, 1,1-dichloroethane, 1,2-dichloroethane, 1,1- dichloroethylene, cis-1,2-dichloroethylene, trans-1,2-dichloroethylene, dichloromethane, 1,2-dichloropropane, 1,1,1,2-tetrachloroethane, 1,1,2- tetrachloroethane, tetrachloroethylene, 1,1,1-trichloroethane, 1,1,2- trichloroethane, trichloroethylene, 1,2, 3-trichloropropane, vinyl chloride, benzene, chlorobenzene, 1,2-dichlorobenzene, 1,4-dichlorobenzene, ethylbenzene, styrene, toluene, m-xylene + p-xylene, o-xylene, nitrobenzene, aniline, 2-chlorophenol, benzo [a] anthracene, benzo [a] pyrene, benzo [b] fluoranthene, benzo [k] fluoranthene, chrysene, dibenzo [a, h] anthracene, Indeno [1,2,3-cd] pyrene, naphthalene. And the monitoring results are, except for pH, all meet the screening criteria of Grade II land use in Table 1 and Table 2 of GB36600- 2018 (pH has no corresponding screening criteria, which is only used as background value). (6) Current situation of sediment environment quality Four monitoring points are arranged in the proposed site and upstream / downstream of the Jiguanshi ship waste receiving and treatment project (including dock basin excavation). The monitoring factors are water content, pH, organic matter content, total phosphorus, petroleum, total arsenic, total mercury, total copper, total zinc, total cadmium, total nickel, total lead and total chromium. And the monitoring results of arsenic, mercury, copper, cadmium, nickel and lead at sites D1-D4 all meet the other screening standards of pH>7 in GB15618-2018. Therefore, the environmental quality of the sediments of the subproject is good, and it is not toxic or harmful; other monitoring indicators have no corresponding screening standards, only used as the background value. 1.5 Environmental impact 1.5.1 Environmental benefit analysis Page 93 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (1) Improve the recycling efficiency of plastic waste and reduce the flow of 1,000t plastic waste into the natural environment every year. (2) Improve the recovery rate and utilization rate of recyclable waste, reduce the consumption of natural resources, decrease the harm of waste to the environment, and enhance the ability of social sustainable development. (3) In the past, the waste of scattered waste transfer stations was directly transported to the waste treatment plant by waste transport trucks. By changing the transport method to 2-stage transportation, the transportation distance from the front end of waste to the waste treatment plant can be reduced from 65km to 28km on average. Moreover, after the scales of the three Waste Secondary Transfer Stations are upgraded, the waste transport vehicles will take the inner ring expressway or the city expressway without passing through the urban area. In this way, about 80 waste transport vehicles on average that were passing through the urban areas and towns every day will be reduced. (4) Enhance the ability of Chongqing to cope with the future waste growth. (5) Improve the overall level of waste sorting and transfer facilities in Chongqing, promote the waste sorting capacity of transfer station in Chongqing, and perfect the supporting domestic waste classification system in Chongqing. 1.5.2 Environmental impact analysis during the construction period (1) Atmospheric environment The waste gas during the construction period mainly includes the dust generated in the construction process of earthwork excavation, site leveling and material loading / unloading, the dust and tail gas generated by transport vehicles, and the waste gas generated during the operation of construction machines and tools. The main air pollutants include particulate matter, NOx, SO2 and so on which emit in a fugitive manner. According to the analogy investigation, the particulate matter concentration in the area 40m away from the construction site will be reduced to less than 0.265mg/m3 after taking dust suppression measures such as water spraying. The distances of the nearest sensitive points to the subprojects’ construction sites are more than 40m. Moreover, the vehicle transportation routes will not pass through the sensitive points such as villages and schools after alternative selection process. Therefore, the construction dust will have very small impacts on the surrounding atmospheric environment and environmental Page 94 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project protection targets. The oil exhaust gas generated from various power machines will exert certain impact on the local ambient air, yet such impact is temporary and will disappear with the completion of construction activities. Both the emission source and emission amount of greenhouse gases (such as CO2 and NOx) generated during the construction period are very small. The greenhouse gases are mainly sourced from running vehicles in a disperse manner. All greenhouse gases are emitted in a fugitive pattern. Therfore it is unnecessary to estimate the emission amount of greenhouse gases. (2) Water environment The wastewater generated during the construction period is mainly consisted of the construction waste water and a small amount of domestic sewage of construction personnel. The estimated amount of flushing wastewater for construction machinery and transport vehicles in various subprojects is 30m3/d (about 6m3/d on each construction site). The pollutant in the washing waste water is dominated by SS, with the concentration of about 1200mg/L and the output of 36kg/d (about 7.2 kg/d on each construction site). After the waste water is pretreated by the oil settling tanks, it will be returned to the construction site for water spraying to remove dust, without outward discharge. Meanwhile, strict management will be conducted on construction machinery to reduce "loss, spill, drip and leakage" of mineral oil, so as to reduce the impact on water environment. There are about 200 construction personnel during the peak construction period (about 40 on each construction site), and the output of domestic sewage on the construction sites is about 16 m3/d (4 m3/d on each construction site). During the construction period, construction camps will be set up in all of the subproject sites for the workers, and the domestic sewage will be collected to the septic tank of each construction camp and then transported by the sewage suction truck to the Wastewater Treatment Plant for treatment. Construction Camp Management Plan is specially prepared for the camps of the Project, including waste water management measures for construction camps. (3) Acoustic environment The noise sources of the project during the construction period mainly include construction machinery noise and traffic noise. The noise can generally reach the level required under the Emission Standard of Environment Noise for Boundary of Page 95 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Construction Site (GB12523-2011) beyond 50m in daytime (standard value 70 dB(A)), and reach the standard limit value beyond 250m in night (standard value 55 dB(A)). The project during the construction period will cause some noise impacts on the residential areas around. In order to mitigate the impact of construction noise, it is recommended according to this EIA to reasonably arrange the construction intensity and properly organize the construction activities, as well as set enclosing wall at the construction site boundary, reduce the devices with high noise or install temporary sound enclosure for the high-noise equipment, keep the construction activity away from the residential area, reasonably design the construction time schedule and adopt other useful measures. According to the experience of similar projects, the noise can be reduced by 10~15 dB(A). However, it is still a little above the standard limit value, so the construction party shall actively communicate with the residents to obtain their understanding. Night- time construction will cause certain impacts on the acoustic environmental protection targets, so it is suggested according to this EIA to forbid night-time construction to reduce the interference to residential areas. In addition, it is suggested to control the transport vehicle’s speed, reduce the whistle and reasonably arrange the transport time schedule etc, so to reduce the impact on the acoustic environmental protection targets. (4) Solid waste The solid waste generated during the construction period mainly includes construction waste, domestic waste of construction personnel and sludge generated from excavation of dock basin. The construction waste is designed to be used as the backfill material, without spoil. The domestic waste is designed to be collected at the designated place on the construction site in a uniform manner, then collected and transported by the environmental sanitation department on a regular basis. The earthwork produced during dock basin excavation is planned to be dried in the mud-dumping yards (It is planned to set 2 or 3 mud-dumping yards at the river bank, and a grit chamber will be set in the lower part near the mud- dumping yards. After waste slags are settled still, the water will return to the main river stream. The hydraulic retention time is about 50h. In the construction process, the alternate use method of the mud-dumping yards is adopted to avoid the increased flow rate caused by too high water level in the mud-dumping yards, and ensure sufficient sediment of waste slags, so to largely avoid possible adverse Page 96 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project impacts of the water return from the mud-dumping yards on the quality of the river water.) Part of the earthwork is designed to be used for land backfill, and the other will be transported to Luoqi landfill. The solid waste will exert minimal impact on the environment after being properly treated. (5) Soil The impacts on soil in the construction period are mainly shown in the following aspects: â‘  In the process of excavation and backfill, the original soil layers will be disturbed and destroyed, and the soil with different layers and textures will be mixed; â‘¡ Soil layers and texture are disturbed and destroyed, resulting in changes in the habitat of microorganisms, protozoa and molluscs in the soil; â‘¢ The waste generated in the construction period may contain substances that are difficult to be decomposed. If not properly treated, they will impact soil quality. (6) Soil and water conservation The total excavation of the subproject is approximately 7,000 m3, primarily generated from excavation of dock basin and flattening construction of platform field. The total backfilling earthwork is approximately 32,000 m3, primarily used for backfill of land platform and road embankment. The borrowed earthwork is approximately 25,000 m3 from the nearby construction projects under the coordination of Chongqing City Administration Bureau. During the construction period, the affected area of the subprojectis about 2.26hm2, and the newly increased soil and water loss is about 150t. In accordance with different construction methods of the subproject, it is divided intoGrade 3 primary prevention and control partitions of soil and water loss, such as land platform and supporting facilities prevention and control partition, land connecting road prevention and control partition, and hydraulic structure prevention and control partition. The soil and water loss protection measures are put forward for different construction stages. After the measures are taken, the soil and water loss will be obviously controlled. (7) Ecological impact The project-affected area primarily involves urban and rural staggered areas, in which urban artificial ecosystem and agricultural ecosystem coexist. There is no natural habitat or critical habitat due to severe impact of human. The common Page 97 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project arbors and scrub-grasslands are distributed in the most of project-affected area. Since they are common local species, they are easy to recover after being affected. Furthermore, the subprojects cover a limited area and hence can only exert minimal impacts on the terrestrial vegetation and plant resources. The project- affected area is seriously altered by human activities, and distributed with a small number of animal species. All of them are local common species, such as rodents, which are good at moving and easy to escape. During the construction period, they are mainly disturbed by noise and will move to the surrounding area. After the construction period is completed, they will return to the original area, so the construction has little impact on terrestrial animals. The aquatic ecological assessment scope of Jiguanshi ship waste receiving and treatment project is obviously influenced by human activities, which belongs to ‘modified habitat’. The water bodies involved in dock basin excavation and other construction activites will be disturbed during the construction period, resulting in the decrease of photosynthetic intensity and quantity of phytoplankton, which will have corresponding impacts on the species and distribution of zooplankton and benthos. Therefore, the excavation of dock basin can directly or indirectly affects the biomass of plankton. Compared with other water related projects in Chongqing, and according to the construction scale of the project, it is predicted by this assessment that the biomass loss of phytoplankton, zooplankton and benthos during the construction period is about 67.0kg, 2.7kg and 6.8kg respectively. The time of dredging and wading construction is short, and the influence of suspended solids will gradually disappear after the completion of construction. Due to the self purification capacity of the water body and the characteristics of plankton and benthos, such as large species, large quantity, universality, wide distribution and strong adaptability, they will soon return to the original level, so it is a reversible effect. The construction of the project will generally cause a small impact on the plankton and banthos of the river section. The impact on fish during the construction period is mainly reflected in the noise and vibration caused by construction machinery, and the increase of suspended solids caused by construction disturbance that may cause harm to fish. The content of suspended matter in water is obviously related to the type of construction vessel, water level and water flow velocity. By using dredger with low sediment resuspension rate and constructing in seasons with low water level and slow water flow speed, the diffusion range of suspended matter can be Page 98 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project reduced and the impact on fish can be controlled. The water level of this section of the Yangtze River fluctuates from 145 m to 175m, and the low water level is 145m from February to June. According to the construction arrangement, the water- related construction activites will take place during this interval. Once the construction begins, fish will be disturbed by the activites. With strong mobility, fish will get far away from the construction area. As the water-related construction, duration is short and with a small influence range, after the construction completion, the driven-away fish will return to this water area. Based on field survey and interview, The fish resources in the assessment area are obviously affected by human disturbance, and the existing fish resources are all common fish species (including some artificially released fish), without rare and protected fish or endemic fish. There are no fish spawning grounds, feeding grounds, wintering grounds and other important habitats in the project assessment area, the construction of the project will not cause obvious impact on it. However, the excavation area only occupies 0.30% of the total area of the construction section of the Yangtze River (assessment scope), so its impact on the plankton and benthos in the area is minimal. During the construction period, the impact on fish is mainly reflected in the noise and vibration generated by construction machinery, as well as the harm to fish caused by the increase of suspended matters arising from construction disturbance in the construction water area. The content of suspended matter in the water is obviously related to the type of construction ship, water level and water flow speed. By using the dredgers with lower sediment resuspension rate and choosing the season with lower water level and slower flow speed for construction work, the diffusion of suspended matter can be controlled and the impact on fish can be reduced. Due to the short duration of the water related construction in the dock basin excavation process and the strong mobility of fishes, it is expected that the expelled fish will return to the water area after the completion of construction period, therefore the project construction will exert minimal impact on the fish in the section. Since there is no critical habitat of wintering ground, spawning ground and feeding ground for the fish arranged in the section of the subproject impact area of the Yangtze River, and the project-affected area is far away from such ‘Three Grounds’ for the downstream fish, the project construction will exert no impact on the fish. Page 99 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 1.5.3 Environmental impact analysis during the operation period (1) Waste gas Jiguanshi ship waste receiving and treatment project : A small amount of ship fuel exhaust gas, automobile exhaust, road dust, and odor gas will be generated during the operation period. The ship waste and floating waste will be discharged into the detachable container of garbage truck loading / unloadingand transferred timely. The containers of sealed structure have little impact on the atmospheric environment during the loading / unloading and transferring processes. The ship sewage will be sent to the wastewater treatment tank in the back container yard via the sewage pipeline, and then discharged into Jiguanshi Wastewater Treatment Plant after being pre-treated. Sealing treatment is conducted in the major process to minimize the impact on the atmospheric environment. Upgrading subprojects of waste transfer stations: A small amount of odor gas and canteen lampblack will be generated during the operation period. After the reconstruction and expansion of each waste transfer station, the discharge of odor will still rely on the original exhaust funnels. The existing exhaust funnels are equipped with an integrated deodorization and purification tower (chemical cleaning + fiber adsorption + biosorption + activated carbon adsorption + ultraviolet disinfection), and the purification device can reduce the concentration of particles, non-methane hydrocarbon and odor by an efficiency of 90%. Based on the existing measures, the concentration of odor produced by the three waste transfer stations can meet the Emission Standards for Odor Pollutants (GB14554- 1993). Therefore, these Waste Transfer Stations exert minimal environmental impact on the surroundings. Luoqi low-value recyclable utilization base: A small amount of non-methane hydrocarbon, odor gas and particles will be generated during the operation period, which are primarily generated from waste plastics melting and cracking. Each production line is equipped with gas collecting hood. After the odor gas is removed by the spray dust removal and deodorization system, it is collected by the gas collecting hood, and the collection efficiency can reach 95%. The collected gas will be sent to the deodorization and purification tower (chemical cleaning + fiber adsorption + biosorption + activated carbon adsorption + ultraviolet disinfection) by negative pressure ventilation system. This purification device can reduce the concentration of particles, non-methane hydrocarbon and odor by an efficiency of Page 100 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 90%. After these measures are taken, the waste gas emitted by Luoqi low-value recyclable utilization base can meet Emission Standards for Odor Pollutants (GB14554-1993) and Integrated Emission Standard of Air Pollutants (GB16297- 1996), which has little environmental impact on the surroundings. (2) Waste water Jiguanshi ship waste receiving and treatment project : The waste water generated during the operation period mainly includes domestic sewage and oil- polluted sewage from ships, domestic sewage from workers and so on. The domestic sewage collected from ships and staff is sent to the domestic sewage regulating tank and treated in the integrated wastewater treatment device to meet the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015). Then it will be sent to Jiguanshi Wastewater Treatment Plant for treatment. The oil-polluted sewage of ships is transported into the ship oil-polluted sewage regulating tank for oil-water separation after going ashore, and then it will be transported to Jiguanshi Wastewater Treatment Plant for treatment after its quality meets the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015) through treatment by the integrated wastewater treatment device. The waste water of the dock will not be directly discharged into the surface water body. Therefore, it has minimal impact on the local surface water environment. According to the prediction, the change of water quality and quantity before and after Jiguanshi wastewater treatment plant receiving the dock’s wastewater is very small, so the impact on the surface water in this river section is negligible. Upgrading subprojects of waste transfer stations: The waste water generated during the operation period is primarily sourced from the leachate, flushing waste water and domestic sewage generated from the garbage stacking and compacting process. During the operation period, the leachate and flushing waste water are treated by the wastewater treatment tank (anaerobic, oil separation, A/O+MBR membrane process) to reach the acceptance standard of the Wastewater Treatment Plant, and then discharged into the Wastewater Treatment Plant for further treatment. The domestic sewage is connected to the municipal pipe network after it reaches the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015) through pretreatment, and then it will be discharged with proper quality after being treated by the Page 101 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Wastewater Treatment Plant. Luoqi low-value recyclable utilization base: The production waste water during the operation period mainly includes leachate, flushing waste water, domestic sewage from staff and a small amount of chemical waste water. The leachate, flushing waste water, domestic sewage from staff are discharged into the municipal pipe network after being pre-treated in the regulating tank. The chemical waste water is collected and temporarily stored separately, and delivered to a qualified hazardous waste disposal unit for disposal. The waste water will not be directly discharged into the surface water body. Therefore, it has little impact on the local surface water environment. (3) Noise Jiguanshi ship waste receiving and treatment project : The noise during the operation period is mainly sourced from the wastewater treatment equipment (the air floatation machine, about 80 dB(A)). According to the prediction, after taking such measures as foundation vibration absorption, regular maintenance, surrounding greening and sound insulation (with a sound insulation effect of about 15 dB(A)), the noise at the plant boundaries will meet the corresponding standards in the daytime and nighttime; As for the protection objects nearest to the subproject, which is a residential point away from the site boundary about 102m, the acoustic environment qualities in daytime and night are predicted to meet the corresponding standards. Therefore the impact on the surrounding residents is acceptable. Upgrading subprojects of waste transfer stations: The noise during the operation period is primarily generated from the operation of compressors, crushers, drum screening machines, blowers and transfer vehicles, with the maximum source intensity as 95 dB(A). According to the prediction, as the equipments of the subprojects are located indoors, with sound insulation effect of the buildings (about 15 dB(A)), the noise at the plants’ boundaries can meet the corresponding standards in daytime and night. As for the protection objects nearest to the subprojects, the acoustic environment qualities in daytime and night are predicted to meet the corresponding standards. Therefore the impact on the surrounding residents is acceptable. Luoqi low-value recyclable utilization base: The noise during the operation period is primarily generated from the operation of crushers, drum screening Page 102 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project machines, blowers and transfer vehicles, with the maximum source intensity as 95 dB(A). According to the prediction, as the equipments of the subproject are located indoors, with sound insulation effect of the buildings (about 15 dB(A)), the noise at the plant boundaries can meet the corresponding standards in daytime and night. As for the protection objects nearest to the subproject which is 409m away from the project site, the acoustic environment qualities in daytime and night are predicted to meet the corresponding standards. Therefore, the impact on the surrounding residents is acceptable. (4) Solid waste Jiguanshi ship waste receiving and treatment project : The solid waste generated during the operation period mainly includes waste oil produced after oil-water separation of oil-polluted wastewater, overhaul waste, ship waste, floating waste and domestic waste from workers. It is designed to set a hazardous waste storage room to temporarily store those hazardous substances such as waste oil and oil polluted cotton gloves, and then transport them to a qualified hazardous waste disposal unit for proper disposal. The ship waste and floating waste are planned to be discharged into the detachable containers of garbage trucks through ship’s own loading / unloading equipment and transferred in time; The domestic waste is planned to be collected together at the dock, then cleared and transported regularly by the environmental sanitation department. The solid waste produced and collected in the subproject will cause little environmental impact after being properly treated. Upgrading subprojects of waste transfer stations: The solid waste produced during the operation period mainly includes biochemical pool sludge, waste MBR membrane, waste activated carbon and waste filler produced by deodorization and purification towers, as well as hazardous waste produced in the process of machinery maintenance and so on. The sludge is cleared regularly and delivered to the incineration plant for disposal Waste activated carbon, waste engine oil, waste cotton yarn and waste gloves are collected and temporarily stored in the temporary hazardous waste storage room in the plant area and delivered to a qualified hazardous waste disposal unit for disposal on a regular basis; Waste MBR membranes and waste fillers are planned to be collected and taken away by the equipment manufacturers without temporary storage in the plant area. The solid waste produced and collected in the Project will cause little environmental impact Page 103 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project after being properly treated. Luoqi low-value recyclable utilization base: The solid waste produced during the operation period mainly includes domestic waste from the staff, restaurant waste, waste residue and a small amount of hazardous waste. The domestic waste and restaurant waste are collected separately and delivered to the environmental sanitation department for disposal. Waste residues are designed to be timely classified, collected and temporarily stored in the general industrial waste storage room in the plant area, and then be regularly delivered to the environmental sanitation department for disposal. Hazardous waste, such as waste activated carbon and waste filter cotton, are planned to be separately collected, temporarily stored in the hazardous waste temporary storage room in the plant area, and then delivered to the qualified hazardous waste treatment unit for proper treatment on a regular basis. The solid waste produced and collected in the subproject will cause little environmental impact after being properly treated. (5) Soil The impacts of Luoqi low-value recyclable utilization base on the soil environment during the operation period mainly include the impacts caused by the leakage of waste water and solid waste on the soil. After classification, the domestic wastewater of staff will be transported into the plant area’s biochemical treatment tank along with the oil polluted biological wastewater which has been pre-treated by the oil separation and sedimentation tank. After the treatment in the biochemical treatment tank, the mixed wastewater will be discharged into the municipal sewage pipeline system while it meets the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962- 2015). oil separation and sedimentation tankGradeAfter pre-treated in the oil separation and sedimentation tank, the separated water of diesel products is planned to be transported to Luoqi Wastewater Treatment Plant for treatment. Those types of wastewater are not directly discharged into theopen environment, with little environmental impact on the surroundings. The solid waste is mainly the cracking residue produced by the cracking process of waste plastics. The cracking residue may contain substances that are difficult to decompose and may cause pollution when entering into soil. The cracking residue shall be collected in a timely manner and temporarily stored in the general industrial waste storage room of the plant area, and shall be sent to the environmental sanitation Page 104 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project department for disposal on a regular basis. (6) Groundwater There is no centralized drinking water source and special groundwater resource conservation zone in the area where Luoqi low-value recyclable utilization base is located. During the operation period, the impact of the subproject on groundwater environment is mainly composed of the impacts of flushing waste water, leachate, domestic sewage from the staff, and a small amount of chemical waste water leakage. If the waste water leaks into groundwater, the concentration of COD, BOD5 and petroleum in groundwater will be increased. The ground of the plant area is hardened, and anti-seepage measures are taken for flushing workshop, alcoholysis kettle, oil separation and sedimentation tank and waste water tank. The leachate and flushing water can be directly discharged into the municipal sewage pipe network after reaching the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015). After classification, the domestic wastewater of staff will be transported into the plant area’s biochemical treatment tank along with the oil polluted biological wastewater which has been pre-treated by the oil separation and sedimentation tank. After the treatment in the biochemical treatment tank, the mixed wastewater will be discharged into the municipal sewage pipeline system while it meets the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015). oil separation and sedimentation tankGrade After pre-treated in the oil separation and sedimentation tank, the separated water of diesel products is panned to be transported to Luoqi Wastewater Treatment Plant for treatment. Ethylene glycol wastewater is temporarily stored in waste water tank and then treated by a qualified hazardous waste treatment unit. The impact on the groundwater environment during the operation period is small. (7) Ecological impact Jiguanshi ship waste receiving and treatment project : The impacts on the terrestrial ecological environment during the operation period mainly include the impacts of waste gas, waste water, noise, solid waste on the surrounding environment and creatures. The impacts can be controlled on the basis of proper prevention and control measures being taken. The surrounding vegetation will not be affected, as well as the animals which temporarily leave due to the construction Page 105 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project activities will return to the peripheral area of the subproject gradually. The project operation has little impact on these animals. The impact on the aquatic environment during the operation period is mainly manifested as the disturbance caused to the fish activities in the dock area due to increase of ship entering and leaving frequency and noise. However, the number of ships entering the port is only about 5/day, and the river reach where the subproject is located has a wide river surface and a broad range for fish activities, so the ships will cause little impact on fish. The ships receiving the service and the ships for floating waste collection berthed at the dock are running in the Chongqing section of the Yangtze River. Therefore, there will be no risk of alien species in the operation process brought by their ballast. The project is a public welfare project for the centralized treatment of ship pollutants, which is conducive to the ecological environment protection of the Yangtze River. Therefore, the negative impact of project operation on aquatic ecological environment is small, and there are long-term positive benefits. 1.5.4 Community health and safety (1) Jiguanshi ship waste receiving and treatment project â‘  Construction period The construction duration of Jiguanshi ship waste receiving and treatment project is relatively long, with a construction site (containing a construction camp). There is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 40m. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction workers come from different regions, this may cause the risk of COVID-19 Page 106 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project transmission. The workers may have conflict with local residents and commit an illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum degree. During the construction process of Jiguanshi ship waste receiving and treatment project, a large amount of transport vehicles will be increased. According to the analogy, there are about 30 material transport vehicles per day in the construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the expressway as far as possible without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. The communities around the project site may be exposed to human, chemical and other hazards caused by the project construction. Sometimes, residents may enter the construction site unintentionally or consciously, and thus encounter hazards, including exposure to hazardous substances, contaminated soil and other environmental media, construction buildings, excavation points and building structures (which may lead to the risks such as falling and being trapped). Infectious diseases may also bring certain health threats to the communities near the project site. The health threats brought by the construction site mainly come from the poor health and living conditions, sexually transmitted diseases and infection caused by vectors. At present, the most concerned infectious disease caused by the flow of people in the construction stage is COVID-19. Parts of the construction workers are migrant population, which increases the risk of the spread of the COVID-19. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Jiguanshi ship waste receiving and treatment project is located in the main urban area, there Page 107 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project are few communities adjacent to the site. There are about 40 workers in the construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of Jiguanshi ship waste receiving and treatment project during the construction period is very low. â‘¡ Operation period During the operation period, Jiguanshi ship waste receiving and treatment project will cause some community health and safety impacts, which include 1) the harm and risk from dust and odor; 2) the harm and risk from noise; 3) and traffic safety risk. The dust and odor generated in the operation period may affect the surrounding communities. The dust mainly comes from the transport vehicles, and the odor mainly comes from the transported garbage. Thanks to the timely and enclosed waste transport mode, the impacts of dust and odor to the surrounding communities are slight. A large amount of waste transport vehicles will be increased during the operation period. According to analogy analysis, there will be about 80-100 waste transfer vehicles every day during the operation period. The noise is mainly generated by transfer equipment and transport vehicles. The analysis on the transfer equipment noise has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. As the increase of transport vehicles, the traffic pressure in the surrounding area will be affected, meanwhile, as the awareness of traffic safety in villages and towns is relatively weak, it is possible to cause traffic accidents. During the operation period, the transport vehicles can run through the existing local road as Tanguang Road to get in Yuhang Avenue, then get in the Shijiazhuang Chongqing Expressway through Kaiying Road, and finally reach Fengsheng waste incineration plant. The whole transport route relies on the existing road ways that are mainly fast tracks and expressways, with no needs to newly build transport roads, and without passing through such sensitive points as school, village and hospital, therefore exert minimal impact on the community traffic safety. Both China and Chongqing have comprehensive regulations to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Page 108 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Jiguanshi ship waste receiving and treatment project is located in the main urban area, there are few communities adjacent to the site. The operators of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of Jiguanshi ship waste receiving and treatment project during the operation period is very low. (2) Upgrading subprojects of the waste transfer stations â‘ Construction period The construction durations of Jieshi, Xiajiaba and Zouma waste transfer station upgrading projects are relatively long, with their construction sites being set in Jieshi Town of Ba’nan District, Fangjiashan-Shuanglonghu block of Yubei District and Shuitouwan-Dengta Village-Zouma Town of High-tech zone respectively. Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camps, and all settlements scattered near the boundary of construction camps are located at distances of more than 100m. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction workers come from different regions, this may cause the risk of COVID-19 transmission. The workers may have conflict with local residents and commit an illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum Page 109 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project degree. During the construction process of the waste transfer station upgrading projects, a number of transport vehicles will be increased. According to the analogy, there are about 15 material transport vehicles per day in each construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the expressway as far as possible without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although the waste transfer stations are located in the main urban area, there are few communities adjacent to the sites. There are about 40 workers in each construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of upgrading subprojects of the waste transfer stations during the construction period is very low. â‘¡ Operation period During the operation period, the community health and safety impacts caused by the waste secondary transfer stations include the following aspects: 1) Physical, chemical and biological harms and risks; 2) Waste leakage risk; 3) Noise harm and risk; 4) Dust and odor harms and risks; 5) Traffic safety risk. The visitors and intruders at the waste transfer stations may face many physical, chemical and biological hazards. Garbage collectors, in particular, often pick up garbage near the waste transfer station, looking for recyclable materials and food residues for raising livestock. These people generally live in the surrounding areas, with poor living conditions and only the most basic clean and sanitary conditions. These garbage collectors may face many risks, including exposure to human excreta, paper soaked with toxic materials, bottles with chemical residues, metal containers with pesticide and solvent residues, needles and bandages discarded by hospitals (containing pathogenic organisms), and batteries containing heavy metals. The exhaust gas from garbage trucks running to or from the treatment sites and the dust from the treatment operations can cause potential community Page 110 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project health risks. Since the transfer, sorting and transportation of waste at Jieshi waste transfer station are conducted in closed mode, waste will not be scattered outside the transfer station. Additionally, a special temporary storage room for household hazardous waste is set up in Jieshi waste transfer station, with strict management system to prevent the visitors and intruders from contacting the household hazardous waste. Therefore, during the operation period, the physical, chemical and biological harms and risks brought by the waste transfer stations to the surrounding communities are slight. There will be a risk of spreading disease if waste leaks outside the waste transfer stations. The garbage leaked outside the waste transfer stations through wind, bird foraging and vehicle transportation will not only attract mice, flies and other vectors, but also make the surrounding communities face the impact of harmful substances. Due to the enclosed operation mode of the waste transfer stations’ transfer, sorting and transportation processes, the waste in site will not be scarttered out of the stations. So the risk of the waste transfer stations’ waste leakage is mininmal. The noise of the waste transfer stations is mainly generated by transfer equipment and transport vehicles. The analysis on the transfer equipment noise has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. In addition, after the optimization and comparison of transportation routes, the garbage transfer vehicles will all take the inner ring expressway or ring expressway without passing through schools, villages and hospitals and other sensitive points, so they will cause little noise impacts on the surrounding communities. The dust and odor generated by the waste transfer stations may cause certain impact on the surrounding communities, and the organic dust can also spread pathogenic microorganisms. Due to the enclosed operation mode of the waste transfer stations’ transfer, sorting and transportation, and as the stations have set up micro-negative pressure ventilation system, odor gas collection hood, dust suppression & deodorization spray device as well as deodorization & purification tower, the waste gas treatment of them is up to the standard (please see the content of Section 5.3.1 for the detail). Therefore, the dust and odor harms and risks brought by the waste transfer stations to the surrounding communities are slight. During the operation process of the waste transfer station upgrading projects, a Page 111 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project number of transport vehicles will be increased. According to the analogy, there are about 80 waste transport vehicles per day during the operation period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the operation period, the transport vehicles will pass through the inner ring or outer ring expressway after transport route optimization without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. Both China and Chongqing have comprehensive regulations to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although the waste transfer stations are located in the main urban area, there are few communities adjacent to the stations. The operation workers of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of upgrading subprojects of the waste transfer stations during the operation period is very low. (3) Luoqi low-value recyclable utilization base subproject â‘  Construction period The construction duration of Luoqi low-value recyclable utilization base project is relatively long, with a construction site being set in Zhujiawan, Taihonggang Village, Yubei District of Chongqing. Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 300m. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction workers come from different regions, this may cause the risk of COVID-19 transmission. The workers may have conflict with local residents and commit an Page 112 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum degree. During the construction process of Luoqi low-value recyclable utilization base project, a number of construction material transport vehicles will be increased. According to the analogy, there are about 15 material transport vehicles per day in the construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the inner ring and outer ring expressways after transport route optimization without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Luoqi low- value recyclable utilization base project is located in the main urban area, there are few communities adjacent to the site. There are about 40 workers in the construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of Luoqi low-value recyclable utilization base project during the construction period is very low. â‘¡ Operation period During the operation period, the community health and safety impacts caused by Luoqi low-value recyclable utilization base include the following aspects: 1) Oil storage and transportation risks; 2) Chemical storage and transportation risks; 3) Noise harm and risk; 4) Dust and odor harms and risks; 5) Textile safety risk. The operation of Luoqi low-value recyclable utilization base has demands of Page 113 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project storage and transportation of diesel and gasoline. Its maximum storage capacity of gasoline is 75.6t and the maximum storage capacity of diesel is 642.6t. In the process of oil storage, there is a risk of leakage and combustion. The influence radius of combustion is 21m, the width of fire dike is 10m, and the distance between the nearest residential area and Luoqi low-value recyclable utilization base is 409m. Therefore, the risk of oil storage is very small. See Chapter 5.7 for details. Oils may cause certain hazards to the communities during the transportation process. The transport vehicles will pass through the inner ring and outer ring expressways after transport route optimization without passing through schools, villages and hospitals and other sensitive points, and with strict management system and management measures (please see Section 7.4.2 for the detail), so to ensure the traffic risk brought by oils is minimal. During the operation period, Luoqi low-value recyclable utilization base will use a certain amount of chemicals, including ethylene glycol, methanol and sodium hydroxide. These chemicals may cause some risks on health and safety of surrounding communities during storage and transportation. The usage of ethylene glycol is 0.75t/d, the recovery is 0.7t/d, and the maximum storage is 1.5T; the usage of methanol is 0.25t/d, and the maximum storage is 2.5t; the usage of sodium hydroxide is 0.1t/d, and the maximum storage is 1t. The distance between Luoqi low-value recyclable utilization base and the nearest residential point is 409m. The transport vehicles will pass through the inner ring and outer ring expressways without passing through schools, villages and hospitals and other sensitive points, and with strict management system and management measures (please see Section 7.4.2 for the detail), so to ensure the traffic risk brought by chemicals is minimal.The noise of Luoqi low-value recyclable utilization base is mainly generated by the treatment equipment. The analysis on the treatment equipment noise has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. The dust and odor generated by Luoqi low-value recyclable utilization base may cause certain impact on the surrounding communities, and the organic dust can also spread pathogenic microorganisms. As the base has set up micro-negative pressure ventilation system, odor gas collection hood, dust suppression & deodorization spray device as well as deodorization & purification tower, its waste gas treatment is up to the standard (please see the content of Section 5.3.1 for the detail). Therefore, the dust and odor harms and risks brought by Luoqi low-value Page 114 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project recyclable utilization base to the surrounding communities are slight. Luoqi low-value recyclable utilization base has a certain potential health risk to the consumers who buy the products made of its textiles. In the operation stage of this subproject, the pH value, pesticide, heavy metal, formaldehyde, chlorophenol, chloroorganic carrier and bioactive finishing agent of recycled textiles should be properly tested, and the characteristics of textiles should be evaluated according to the specific conditions of use before entering the market. Both China and Chongqing have comprehensive regulations to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Luoqi low-value recyclable utilization base is located in the main urban area, there are few communities adjacent to the site. The operators of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of Luoqi low-value recyclable utilization base project during the operation period is very low. 1.5.5 Occupational health and safety (1) Jiguanshi ship waste receiving and treatment project â‘  Construction period Jiguanshi ship waste receiving and treatment project has some occupational health and safety risks during the construction period, mainly including (1) risks of human body hazards (such as human body being trapped, caught or impacted by mechanical parts, working at height, hearing damage caused by noise, electric shock, high-temperature operation, damage to vision caused by welding); (2) chemical hazards (risks of workers' respiratory tract irritation, discomfort and illness caused by poor air quality, property loss, injury or death of staff caused by fire, etc.); (3) drowning hazard. Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Therefore, the risk rating of the impact from Jiguanshi ship waste receiving and treatment project’s construction period to the occupational health and safety of the staff is ‘Substantial’. â‘¡ Operation period Page 115 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The Jiguanshi ship waste receiving and treatment project involves high temperature operation, drowning and other hazards. The workers will frequently contact the waste (including hazardous waste) with odor, which contains toxic and hazardous substances, a large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches. The odor will cause adverse impact on the breathing, blood and digestive system. The large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches may cause disease. Thus, the rating of the impact of Jiguanshi ship waste receiving and treatment subproject’s operation period on the occupational safety and health is ’Substantial’. (2) Upgrading subprojects of the waste transfer stations â‘  Construction period The daily waste treatment capacities of Jieshi, Xiajiaba and Zouma Waste Secondary Transfer Stations are 4,630 tons, 3620 tons and 3890 tons respectively. During the reconstruction period, the working units of the waste secondary transfer stations will not be all shut down (about 25% of the units will be shut down due to the construction process). In order to meet the demand of daily waste transfer capacity, this will have certain impact on other working units. First, the work intensity of the remaining units will increase. Second, the working hours of the remaining units will increase as well. Long term work with high intensity and long operation hours will also affect the physical and mental health of the staffs, making their immunity get weakened and more vulnerable to the bacteria in the waste, so to lead to a growing risk of illness. Long-time work will also bring certain damage to mechanical equipment, for example, the lack of timely maintenance will increase the risk probability of safety accidents. In addition, there are other occupational health and safety risks during the construction period of the subprojects, mainly including (1) risks of human body hazards (such as human body being trapped, caught or impacted by mechanical parts, working at height, hearing damage caused by noise, electric shock, high-temperature operation, damage to vision caused by welding); (2) chemical hazards (risks of workers' respiratory tract irritation, discomfort and illness caused by poor air quality, property loss, injury or death of staff caused by fire, etc.). Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Page 116 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Therefore, the risk rating of the impact from the waste transfer station upgrading projects’ construction period to the occupational health and safety of the staff is ‘Substantial’. â‘¡ Operation period The workers will work in confined space during working hours, and be exposed to noise, mechanical and chemical damage. The workers of the waste transfer stations will frequently contact the waste (including hazardous waste) with odor, which contains toxic and hazardous substances, a large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches. The odor will cause adverse impact on the breathing, blood and digestive system. The large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches may cause disease. Thus, the rating of the impact of the waste transfer stations’ operation period on the occupational safety and health is ’Substantial’. (3) Luoqi low-value recyclable utilization base â‘  Construction period Luoqi low-value recyclable utilization base subproject has occupational health and safety risks during the construction period, mainly including (1) risks of human body hazards (such as human body being trapped, caught or impacted by mechanical parts, working at height, hearing damage caused by noise, electric shock, high-temperature operation, damage to vision caused by welding); (2) chemical hazards (risks of workers' respiratory tract irritation, discomfort and illness caused by poor air quality, property loss, injury or death of staff caused by fire, etc.). Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Therefore, the risk rating of the impact from Luoqi low-value recyclable utilization base project’s construction period to the occupational health and safety of the staff is ‘Substantial’. â‘¡ Operation period The workers will work in high temperature condition or confined space during working hours, and be exposed to noise, mechanical and chemical damage. In addition, Luoqi project involves high pressure amd temperature risk, toxic and Page 117 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project harmful substances (diesel oil, gasoline) and chemicals (methanol, ethylene glycol). Exposure to diesel oil and gasoline may have adverse effects on nervous system, respiratory tract and skin; exposure to methanol may have adverse effects on nervous system and visceral organs; exposure to ethylene glycol may have adverse effects on digestive tract, respiratory tract and nervous system; in addition, diesel oil, gasoline and methanol may have combustion risks. Thus, the rating of the impact of Luoqi low-value recyclable utilization base’s operation period on the occupational safety and health is ’Substantial’. 1.5.6 Environmental risk analysis The first-batch subprojects contain some environmental risks, including 1) Jiguanshi ship waste receiving and treatment project has possible risk of diesel oil leakage caused by collision of ships entering and leaving the port during the construction and operation periods; 2) Luoqi low-value recyclable utilization base has possible risk of oil leakage during the oil storage; 3) Luoqi low-value recyclable utilization base has possible risk of methanol leakage during the methanol use and storage. (1) Risk of oil spill According to the feasibility study report of the Jiguanshi ship waste receiving and treatment project, the site is close to the Xiayaogou anchorage, and there is a small overlap between the turning water area of the proposed No.2 ship waste receiving pier and the anchorage. During the construction period of the Jiguanshi ship waste receiving and treatment project, there will be a small amount of construction vessels all in the water area near the dock. As they are still in a distance from the anchorage, their impacts on the anchorage are relatively slight. As the increase of inbound and outbound vessels during the operation period, they may collide with the ships of the anchorage. However, as there are only about 5 vessels entering the port every day, the probability of collision is very low. (2) Oil storage The daily output of oil is 54t, of which 10% is gasoline, 85% is diesel oil, and 5% is wax oil. Wax oil is not a hazardous environmental risk substance, so it is not analyzed. Page 118 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Diesel oil and gasoline leaking to the soil will mainly pollute the plants growing in the soil, inhibit the growth of plants, and affect the absorption of nutrients by the plants. The maximum storage capacity of gasoline is 75.6t, and the maximum storage capacity of diesel is 642.6t. In accordance with the Technical Guidelines for Environmental Risk Assessment on Projects (HJ 169-2018), the threshold storage quantities of gasoline and diesel oil are both 2,500t. Q = q1 / Q1 + q2 / Q2 q1,q2 ——Maximum storage capacity of diesel oil and gasoline Q1, Q2 ——Threshold storage quantity of diesel oil and gasoline Result: Q=0.29 <1 Therefore, the oil storage will result in low environmental risk that can be controlled to the acceptable level by strengthening management and introducing the risk reduction measures. (3) Methanol A certain storage capacity of methanol, as the raw material used in Luoqi low- value recyclable utilization base, will be provided. Methanol is easy to volatilize, and after inhalation of a large amount of methanol in a short time, the workers will present mild eye and upper respiratory tract irritation symptoms (gastrointestinal tract irritation symptoms after oral administration), headache, dizziness, fatigue, drunkenness, and hazy consciousness after a period of latent period; as the nearest residential area is 409m from Luoqi low-value recyclable utilization base, the methanol vapor will not be diffused to it, and this will not produce impact on surrounding residents. The daily consumption of methanol is about 0.25t, and the maximum storage capacity of methanol is 2.5t for 10 days of consumption. In accordance with the Technical Guidelines for Environmental Risk Assessment on Projects (HJ 169-2018), the threshold storage quantity of methanol is 10t. Q = q1 / Q1 q1 ——Maximum storage capacity of methanol Q1 ——Threshold storage quantity of methanol Page 119 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Result: Q=0.25 <1 Therefore, the methanol, as the raw materials for the subproject, will result in low environmental risk that can be controlled to the acceptable level by strengthening management and introducing the risk reduction measures. 1.5.7 Safety risk assessment This project includes some safety risks, such as: 1) fire accident caused by oil leakage in Luoqi low-value recyclable utilization base; 2) explosion accident of Luoqi low-value recyclable utilization base’s methanol storage house; 3) fire accident of the 5 subproject’s waste plastic temporary storage rooms. (1) Oil storage Luoqi low-value recyclable utilization base of the Project will produce oils with the daily output of 54t, including 10% as gasoline and 85% as diesel oil. The leakage of diesel oil and gasoline will cause a fire safety risk. The mathematical model analysis method of pool fire accident consequences is applied to determine the degree of fire hazard impact. As the gasoline storage tank is 200m3, and the diesel storage tank is 2×500m3, the fire dike is 80m in length, 10m in width and 1.5 m in height. As the maximum gasoline storage amount is 75.6t and the maximum diesel storage amount is 642.6t, this assessment is focused on the analysis of fire accident caused by leaked diesel storage tank. Once the tank body is broken, the liquid will spread along the ground and will flow to the fire dike to form a liquid pool. According to the results of the mathematical model analysis method of pool fire accident consequences, as for the leakage of diesel oil results in liquid pool burning, the safe distance from the target to the center of the liquid pool is 21 meters, and the width of the fire dike is 10 meters. Therefore, the area beyond 16 meters away from the fire dike is safe. Considering the distance between the fire dike and the nearest affected target is 17 meters, the oil storage will not cause great damage to staff and facilities. The distance from the fire dike to the nearest resident is 409 meters. As a result, the fire accident of the tank farm will not cause damage to surrounding communities. (2) Methanol storage A certain storage capacity of methanol, as the raw material used in Luoqi low- Page 120 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project value recyclable utilization base, will be provided. Methanol is easy to volatilize, and can generate explosive mixture when mixing with air. It will cause a risk of burning and explosion after exposure to heat and open flames. The maximum storage capacity of methanol is 2.5t. Shock wave overpressure generated by methanol explosion is its main hazard. The traditional TNT equivalent coefficient method is applied in this model to simulate and calculate the shock wave overpressure, and predict the severity of the methanol explosion. Based on the calculation result, the lethal radius of methanol is 3m, and the serious injury radius is 9m. It is necessary to keep the staff dormitory and production workshop from the methanol storage room at a safe distance of more than 9m, and hazard warning signs shall be posted. The methanol explosion will not cause huge harm to the staff or damage to equipment and surrounding communities. (3) Temporary storage of waste plastics During the implementation and operation of the first five subprojects of the Project, the plastic waste will be transported at a capacity of 145t/d, and the maximum temporary storage of plastic waste is 50t. The investigation shows that the plastic waste contains water, and is transported in a fully confined space without open fire. Deodorant spray, which contains water, will be used to deodorize the Waste Transfer Stations and Luoqi low-value recyclable utilization base, and the plastic waste will be broken with water during the sorting process. There is still fire risk in the Project. When each subproject is operating, well- established fire-fighting measures shall be developed for each subproject, including providing sufficient fire equipment and conducting fire education to workers, so to reduce the risk of waste plastic temporary storage fire accident to the minimum degree. 1.5.8 Cleaner production (1) Energy saving evaluation The energy consumption data of the subprojects is listed in the table below. Table 1.5-1 Energy consumption of the subprojects Page 121 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Converted to Subproject name Energy type Energy consumption standard coal Jiguanshi ship waste receiving Electricity 630 kW·h/a 774.27 tce and treatment project Diesel / / Luoqi low-value recyclable Electricity 726.52*104kW·h/a 893.6196 tce utilization base project Diesel / / Jieshi waste transfer station Electricity 531.46*104kW·h/a 653.70tce upgrading project Diesel 2867.82 t/a 4178.7 tce Xiajiaba waste transfer station Electricity 531.46*104kW·h/a 653.70tce upgrading project Diesel 2867.82 t/a 4178.7 tce Zouma waste transfer station Electricity 4178.7 tce 240.10tce upgrading project Diesel 796.62 t/a 1160.75 tce The energy consumption of each subproject is small, and the equipment selection meets the national energy consumption standard, which accounts for a low proportion of local energy consumption. It will not cause negative impact on the energy consumption intensity of the local area and Chongqing during the "14th five year plan", so the impact is slight. (2) Water saving evaluation The water demand of all subprojects is shown in Table 1.5-2. Table 1.5-2 Water Demand of the Subprojects Jiguanshi Luoqi low- Xiajiaba Zouma Project Jieshi Waste ship waste value Waste Waste name Transfer receiving recyclable Transfer Transfer Station and utilization Station Station Water upgrading treatment base upgrading upgrading consumption project project project project project Water consumption 6171 14.6*104 9.58*104 9.58*104 2.9*104 t/a The subprojects are located in the areas with rich water resources, and the water demand is very low, which will not cause pressure on the local water resources. Therefore, each subproject has little impact on local water use. Page 122 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (3) Reduction of raw materials consumption The subprojects’ raw materials consumption reduction measures are listed in the table below. Table 1.5-3 The subprojects’ raw materials consumption reduction measures Project name Measures Effects As the ships are equipped with Jiguanshi ship The scheme of ramp-dock & loading/unloading equipment, waste receiving river-connecting road is so it is no need for this and treatment adopted; subproject to newly purchase project loading/unloading equipment.

These chemicals have some risks during the scenes of use, storage and transport, so it is necessary to formulate some management requirements to reduce these risks. The management requirements are listed in Table 1.5-3. Table 1.5-5 Chemical management Chemical Scene Amount Measures 1) It is necessary to strengthen ventilation while Ethylene operating in a confined space; 2) Operators shall be Use 0.05t/d specially trained and strictly abide by the operating glycol procedures; 3) Wear protective articles during work; 4) Handle with care to prevent vessel Page 124 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Chemical Scene Amount Measures damage; 5) Keep away from all fire sources, heat sources, strictly prohibit contact with oxidants; 6) Provide the appropriate variety and quantity of fire-fighting equipment and emergency leakage treatment equipment;7) Bathe and change clothes after use, and pay attention to personal hygiene and safety. 1) Store in a galvanized iron bucket; 2) Store in a cool, dry and ventilated warehouse; 3) Keep away from fire, provide anti-static protection, and keep the container sealed; 4) Keep away from oxidants, Storage 1.5t heat sources and direct sunlight; 5) Provide the appropriate variety and quantity of fire-fighting equipment and emergency leakage treatment equipment. 1) Store it in sealed galvanized iron bucket and transported by tank wagon; 2) The tank wagon shall be equipped with grounding chains and orifice plates can be provided in it for mitigating static produced by vibrations. 3) The ethylene glycol cannot be transported with oxidant or other chemicals at the same time; 4) Avoid Transport / transportation in high temperature weather, prevent exposure to the sun, rain and high temperature circumstance, and keep away from fire, heat sources, and high temperature areas during transportation; 5) Provide the appropriate variety and quantity of fire-fighting equipment and emergency leakage treatment equipment. 1) It is necessary to strengthen ventilation while operating in a confined space; 2) Operators shall be specially trained and strictly abide by operating procedures; 3) Wear protective articles during Use / work; 4) Keep away from all fire and heat sources; 5) Provide the appropriate variety and quantity of DMT fire-fighting equipment and emergency leakage treatment equipment.

The scheme of Not-to-do would not give rise to environmental impact in that there is no construction and operation periods, and the scheme of To-do will bring certain environmental impact, but such the impact can be avoided and reduced by appropriate environmental protection measures, and the environmental impact during the construction period is temporary, while the project implementation and operation will bring long-term social and environmental benefits. Furthermore, the project construction will reduce the pollution of plastic waste to the environment, enhance the resource utilization capacity of plastic waste, increase oil reserves, transform waste into energy, improve the quality of life of residents, increase employment opportunities, and create long-term social and environmental benefits; Therefore, from the perspective of society and environment, the scheme of To-do is better than the scheme of Not-to-do, so the necessity of the project implementation is proven. 1.6.2 Alternative selection of site (1) Jiguanshi ship waste receiving and treatment project The Jiguanshi ship waste receiving and treatment subproject requires the construction of engineering dock along the Yangtze River. Considering the factors such as water depth, land area, navigation conditions and ecological environment, Page 127 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 2 schemes, as Scheme 1 (the site in the south of Jiguanshi sewage treatment plant) and Scheme 2 (the site in the north of Jiguanshi sewage treatment plant), are determined as the possibly proposed sites for alternative selection. In terms of social impact, Scheme 1 covers an area of about 6200m2, so there is no need to relocate, while Scheme 2 covers an area of about 6500m2, with about 20 households need to be relocated, so Scheme 1 is better. As for the total investment, Scheme 1 needs about 116.2396 million yuan, and Scheme 2 needs about 132.1537 million yuan, so Scheme 1 is better. In terms of environmental impact, there are about 70 retail investors around Scheme 1 site, with a smaller amount of water and soil loss, while there are about 200 retail investors around Scheme 2 site, with a larger amount of water and soil loss, so Scheme 1 is better. And technically, Scheme 1 has a flatter terrain than Scheme 2, with better construction condition. To sum up, Scheme 1 is better than Scheme 2 in all aspects such as social impact, environmental protection, construction condition and so on, so it is the preferred scheme. (2) Waste Secondary Transfer Station The facility upgrading subprojects of Jieshi, Xiajiaba and Zouma Waste Secondary Transfer Stations have existing sites to rely on, and that can reduce the negative impacts such as land acquisition, relocation, construction and soil loss. In addition, the reconstruction and expansion projects can be implemented based on the facilities of the original transfer stations, so it is the only feasible scheme to execute the reconstruction and expansion process relying on the original transfer stations. (3) Luoqi low-value recyclable utilization base As for the proposed site of Luoqi low-value recyclable utilization base, the terrain is relatively flat; the surrounding residential areas are few; it is close to the expressway with convenient transportation condition; and at present, the relevant land acquisition work has already been completed. If another site is selected, the land acquisition is required again, resulting in social impact such as land acquisition and relocation. Even worse, the demolition and construction will lead to an increase of environmental impact and risk, as well as of the land acquisition costs. Therefore, the relocation of Luoqi low-value recyclable utilization base requires certain technical research support. The construction within the scope of acquired land is a preferable scheme in terms of society, Page 128 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project environment, economy and technology, so it is the only feasible site selection scheme. 1.6.3 Alternative selection of technology and process (1) Jiguanshi ship waste receiving and treatment project According to the site topography and adjacent buildings, combining with the process requirement of ship waste going-ashore, the design unit puts forward two construction schemes for the ship waste receiving and treatment project taking into account the ship pollutant landing process requirements. The first scheme is to build sloped dock and river-connecting road, and the second is to build vertical overhead platform. In terms of social impact, the piers’ bank line occupation of Scheme 1 is 250m, with certain safety risk of the river-connecting road, wihle the piers’ bank line occupation of Scheme 2 is 109m, with lower safety risk, so Scheme 2 is better. In terms of cost, the operation cost of Scheme 1 is 0.75 million Yuan/Year, and that of Scheme 2 is 1.1 million Yuan/Year, so Scheme 1 is better. About environmental impact, the excavation volume of Scheme 1 is about 6946m3, and that of Scheme 2 is about 7852m3, therefore Scheme 1 will cause less water and soil loss and smaller ecological impact. Technically, Scheme 1 has lower technical requirements and does not need to purchase new equipment, and Scheme 2 has higher technical requirements and will cause some original equipment to be idle. Therefore, Scheme 1 is better. So, comprehensively, Scheme 1 is better in economy, environment and technology, and it is preferred. The subproject involves dock basin excavation. In order to reduce the impact of suspended solids on water environment quality and aquatic ecological environment, an alternative analysis is carried out for commonly used dredgers and corresponding excavation methods. Scheme 1 is to adopt grab type dredger, while Scheme 2 is to use trailing suction hopper type dredger. In social impact, the 2 schemes are both low in safety risk. About operation cost, the 2 scheme are both 10~30 Yuan/m3. In terms of environmental impact, Scheme 1 results in less suspended solids and has a smaller impact on the water environment quality and aquatic ecological environment than that of Scheme 2, so Scheme 1 is better. In technic aspect, the technologies applied in both schemes are mature and feasible. To sum up, the 2 schemes are basically equal in social impact, economy and technology, as Scheme 1 is better in environmental impact, therefore Scheme 1 is Page 129 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project preferred. (2) Comparison and selection of waste compression technologies The mainstream waste compression technologies applied in Waste Transfer Stations include vertical compression technology and horizontal compression technology. In order to improve the environmental and social benefits brought by the upgrading projects of the Waste Secondary Transfer Stations, two kinds of waste compression technologies are compared, namely vertical compression technology as Scheme 1, and horizontal compression technology as Scheme 2. As for social impact, Scheme 1 has higher space utilizing rate, performs more properly in sorting and transfer, and can keep working in power failure and other emergencies; while Scheme 2 has lower space utilizing rate, performs less properly in sorting and transfer, and must suspend in power failure and other emergencies, so Scheme 1 is better. In terms of environmental impact, Scheme 1 can keep leachate from leakage, while Scheme 2 has possible risk of leachate leakage, which leads to secondary pollution and larger demand of cleaning water, so Scheme 1 is better. In economy, Scheme 1 requires lower maintenance cost with better overall economy. And technically, the 2 schemes are both reliable and feasible. In general, Scheme 1 is better, so it is preferred. (3) Comparison and selection of wastewater treatment facilities Domestic sewage, production waste water and other waste water will be produced by the subprojects of the Project, so it is necessary to use the integrated wastewater treatment facilities as the waste water treatment station. There are 2 different sewage treatment processes as Scheme 1 (MBR treatment process) and Scheme 2 (SBR treatment process) for comparison. In social impact, Scheme 1 has higher space utilizing rate with smaller land occupation, and Scheme 2 needs larger land area with lower space utilizing rate, so Scheme 1 is better. In environmental aspect, Scheme 1 has flexible and continuous water output, with higher removal rate, and less production of settled sludge, so Scheme 1 is better. In terms of economy, the equipment cost of Scheme 1 is about 50000 yuan, and that of Scheme 2 is about 30000 yuan, so Scheme 2 is better. The 2 schemes are both reliable and feasible in technology. In summary, Scheme 1 is better in social and environmental impact, so it is preferred. (4) Alternative analysis on waste plastic cracking oil production Page 130 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project technology The construction content of Luoqi low-value recyclable utilization base subproject contains the special production line of plastic cracking oil production. This assessment conducts the alternative analysis on the 2 different waste plastic cracking oil production technologies, in which the scheme 1 is Cracking & Catalytic Upgrading Process, and the scheme 2 is Thermal Cracking Process. As for social impact, Scheme 1 occupies a larger land area than Scheme 2, so Scheme 2 is better. In terms of environmental impact, comparing with Scheme 2, Scheme 1 has lower reaction temperature, less pollutant discharge amount, faster reaction rate and higher efficiency in waste plastic treatment, so Scheme 1 is better. In terms of economy, the equipment cost of Scheme 1 is about 48 million yuan, the product oil quality is higher, and the annual income is about 28 million yuan. The equipment cost of Scheme 2 is about 20 million yuan, the product oil quality is lower, and the annual income is about 4 million yuan. Therefore Scheme 1 has better long-term economic benefits and is generally better. The 2 schemes are both technically reliable and feasible. To sum up, Scheme 1 is superior to Scheme 2 in environmental impact and economy, so Scheme 1 is the preferred scheme. (5) Comparison and selection of transportation routes • According to the analysis, the Jiguanshi ship waste receiving and treatment project, the upgrading projects of Xiajiaba, Zouma and Jieshi Waste Secondary Transfer Stations can rely on the original roads in the whole process, without additional transport roads to be built. This transportation route mainly consists of fast track and expressway, producing little social and environmental impacts on the communities along the route. So this route scheme is economically and technically feasible, and it is the only preferred one. • Transport vehicles can reach the site of Luoqi low-value recyclable utilization base via two toll stations at Baijiayan or Jiantuowan in the Shanghai- Chongqing Expressway. The scheme 1 (passing through Baijiayan Toll Station) has fewer residential areas than that in the scheme 2 (passing through Jiantuowan Toll Station) along the route, away from water bodies, and the impacts and risks of the scheme 1 on the environment and society are remarkably lower than those of the scheme 2. Therefore, the scheme 1 is the better as a whole and is the preferred one.

Therefore, it is necessary for this project during the construction period to take some special environmental impact mitigation measures. Please see Table 1.7-3. Table 1.7-3 Special mitigation measures for Jiguanshi ship waste receiving Page 140 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project and treatment project Impact Mitigation measures factor 1) The excavation area of the harbor basin is mainlywater related construction. During the construction period, the dredger is used for construction. It is necessary to do manage the collection and transportation of earthwork well, and timely transport it to the designated place for backfill. It is forbidden to temporarily stack or even discard the abandoned earthwork on the river bank. The construction team should connect earthwork excavation with transportation well, and try to achieve that earthwork can be transported away immediately after excavation. 2) Before the construction: one temporary drainage ditch is set at the Basin upstream side of overhead ramp, and a temporary grit chamber is excavation set at the outlet of the drainage ditch. The construction diversion shall be prepared well before the construction of wading pile foundation. 3) During the construction: Woven bag temporary retaining wall is set around the land pile foundation for blocking, and non-woven fabric is used to cover the disturbed bare surface and temporary storage of sandy materials. 4) Later stage of construction: The vegetation restoration area and temporary construction area in the site shall be prepared and sown for greening 5) Two or three mud dumps are set on the river bank, and a grit chamber is set at the lower part near the mud dumps. After the waste slag staticly settles, the water in the mud dumps will return to the main stream, and the hydraulic retention time is about 50 hours. In order to avoid the increasing flow velocity caused by too high water head in the mud dumps, and ensure that the waste slag Sludge can be fully precipitated, the mud dumps are alternately switched to use in the construction process. This greatly avoids the adverse impacts on the water quality of the river caused by the backwater from the mud dumps. The earthwork generated from the excavation of the harbor basin is dried in the mud dumps, part of which is used for land backfilling, and the rest of which is transported to Luoqi landfillsite. （3） Main mitigation measures on environmental impact during the operation period During the operation period of the project, measures are mainly taken for waste gas, waste water, noise and solid waste, in order to minimize the environmental Page 141 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project impacts during the operation period of the project.

The first stage has been implemented from September to November 2020, and the second stage has been carried out from November to December 2020. In the first stage of the SEP, the PMO and the Environmental and Social Impact Assessment Unit disclosed the project information through online announcements and conference release. The project team utilizes the symposiums, training sessions, on-site investigations and interviews to understand the needs of stakeholders, identified the environmental and social risks of subprojects, discussed the mitigation measures, , and obtained the requirements for legal procedures required for the project as well as the guidance from relevant departments. Meanwhile, the implementation unit Chongqing Environmental Sanitation Group and the Environmental and Social Consulting Unit conducted online questionnaire survey on stakeholders in the central urban area within the scope of Chongqing, and the respondents included residents, property managers and staff inthe implementation unit. A total of 5212 stakeholders completed the Page 178 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project questionnaire. According to the statistical results of the SEP implementation in the first stage, the Project has a good social foundation and high support rate of local residents. Most of the respondents think that the Project will generate positive environmental benefits. In the second stage of the SEP, the environmental consulting unit has disclosed the environmental and social preparation documents (draft for comments) to stakeholders in the website (http://www.cqmsy.com/contents/1636/24309.htm). Moreover, the PMO, Project Implementation Units, community leaders, and Environmental and Social Consulting Unit will not only disclose the environmental and social information of the Project to stakeholders by means of internet, newspaper, notices, broadcast and forums, but also carry out stakeholder consultation by means of forums, seminars, focus group interviews, key informants interviews, questionnaires and "12369" hotline, so that stakeholders can put forward rich suggestions on project design and implementation. The project team encourages the stakeholders to give feedback, and timely consider and respond to feedback, so as to support the active participation of stakeholders. Page 179 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 2 Project Description 2.1 Project background China has placed transition to a more balanced and sustainable economic growth model at the center of its development agenda for the decades to come. Commitments in key policy documents including the 13th FYP (2016-2020) and the 19th Party Congress Report (October 2017), include reversing environmental degradation and tackling climate change. Preparation for the 14th FYP was officially launched in November 2019. The plan is expected to continue this emphasis with a renewed focus on waste recycling and reuse, environmental monitoring and information systems, among others 20. In the past four decades, remarkable achievements have been made in the China's economic development. Meanwhile, the rapid economic development poses a serious challenge to the environmental sustainability. A 2015 scientific study 21 estimated that China is a significant contributor to ocean plastic debris and that its rivers are major conduits of such debris reaching the ocean. China is estimated to produce more than 400 million tons of solid waste is produced in China’s urban areas every year, in which about 12% of solid waste is plastic waste. While urban China is reported to have near universal safe disposal rate 22 , rural China is estimated to safely dispose only half of its MSW23. Plastic pollution is also caused by microplastics found in the compost produced by urban kitchen waste treatment plants and plastics in bulky and construction waste. China has the largest in the world agricultural area under plastic films that are not universally collected contributing substantially to plastic pollution of soils and subsequent plastics run off into the marine environment. China has become a major source of marine plastic waste in the world. In response to this severe challenge, the Chinese government attaches great importance to the prevention and control of solid waste and plastic waste 20 The Beijing News. The Ecology and Environmental Minister: 14th Ecology and Environmental FYP needs to take a strategic approach, 2019. 21 Jenna R. Jambeck, Roland Geyer, Chris Wilcox, Theodore R. Siegler, Miriam Perryman, Anthony Andrady, Ramani Narayan, Kara Lavender Law, Plastic Waste Inputs from Land into the Ocean, Science Magazine, February 2015. 22 National Bureau of Statistics of China, China Statistical Yearbook, October 2018. 23 China Association of Urban Environmental Sanitation, The China Municipal Waste Development Report , October 2017. Page 180 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project pollution. The management of solid waste and plastic waste is in a rapid upgrading process aiming for reduction in amount, recycling as resource and disposal after proper treatment. Both ‘downstream’ solutions (postconsumer, such as waste collection, recycling and disposal) and ‘upstream’ solutions (pre-consumer, such as plastic substitution, plastic waste prevention and reduction) recognized to be applied in parallel. In rural areas, efforts will be focused on extending municipal waste collection services and increasing the safe disposal rates; as well as pilots to find a scalable model for agricultural film handling. In urban areas, efforts will be to increase the recycling rate, which currently stands at about 16% mainly due to contribution by the informal sector and improve source separation. At the central level, policy directions to reduce pollution control, increase recycling, enhance prevention have been issued. Much of the downstream regulatory frameworks that would allow to achieve the set policy direction are yet to be developed. Despite progress so far and the clear ambition to advance policies and implementation practices towards reduced pollution and plastic leakage, increased recycling, and prevention, a lot remains to be done. There is institutional fragmentation in service planning and delivery and lack of well-articulated performance systems linked to actual waste volumes produced and handled. Significant operational and financial difficulties remain in rural areas to organize the system such that all waste is collected and safely handled. Rural areas also experience large gaps in data availability and reliability. In urban China, the rolling out of separate waste collection has proved challenging too. Where separation at source is not in place or with insufficient quality, the recycling rate and quality of kitchen waste compost suffer. At the policy level, the specific policy implementation drivers, such as economic and financial incentives and regulatory mechanisms that would underpin prevention and plastic waste reduction are not yet in place. Addressing plastic pollution and management requires a multisectoral effort, through upstream analytical and policy work on plastics, and improvements to the solid waste management sector, river water quality through programmatic cleaning efforts, and the plastic applications and handling in agriculture. With its improving policy, planning, regulatory mechanism, information management, infrastructure and institutional capabilities, China plans to cooperate with the World Bank for the implementation of China Plastic Pollution Reduction Project (P174267). The Project aims to strengthen policy and institutional Page 181 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project capacities for plastic waste management at the national and local levels and to reduce the pollution of municipal solid waste. It comprises of 3 subprojects: (1) Support on policy and institutional capacity strengthening at the national level; (2) Technical assistance and institutional capacity building at the provincial / municipal and local levels; (3) Demonstration of solid waste / plastic pollution reduction, recycling and disposal after proper treatment in selected provinces / cities. In addition to this project which focuses on upstream policy and analytical support and solid waste management investments in two provinces, the World Bank is currently preparing two separate investment operations linked to river basins and the agricultural sector that include attention to marine plastics: (i) China: Yangtze River Revitalization Program which among other areas will also address the challenges of marine plastics flowing into China’s longest rivers; and (ii) China: Food Safety and Plastic Reduction which will among others also focus on plastic food packaging. An ongoing technical assistance funded by the ProBlue Multi Donor Trust Fund is looking into contributing sources of plastic pollution, river transmission mechanisms and will offer benchmarking of plastic waste management mechanisms with those internationally. The proposed project will support the policies, regulations and programs that China has adopted to reduce plastic pollution and improve solid waste management at national level and in two demonstration provinces. The project will help reinforce the policy measures envisaged under the policy note “Further Strengthening Plastic Pollution Controlâ€? issued by NDRC and MEE (January 2020), the new Law on Solid Wastes (April 2020), and the “Notice on Further Promoting Plastic Pollution Managementâ€? issued by 9 ministries including NDRC, MEE, MOHURD, MARA and Ministry of Commerce (July 2020). The project will closely align its activities with NDRC’s upcoming “Plastics Reduction Pilot Programâ€? and the on-going “Implementation Plan of Domestic Wastes Classification System (updated in 2019)â€?. The project will align with the national programs on agricultural mulching film recycling (MARA, 2017), and pilot initiatives on rural waste separation and recycling (MOHURD, 2020). The proposed project will support the implementation of the policy agenda as well as activities to improve urban and rural waste management practices. Through analytics and technical assistance, the project will support selected activities envisaged by NDRC and MEE towards developing instruments, mechanisms and Page 182 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project regulatory frameworks to advance the pollution reduction, plastic waste prevention and minimization policy objectives. It will also support investments in two provinces, on demonstration basis, to improve urban and rural waste management practices. Chongqing was selected as one of the demonstration cities because a typical depiction of most of urban China where separation at source is just commencing. The city aims to increase its recycling rate, improve sorting and waste treatment processes. In addition, two rural districts in Chongqing will pilot waste systems with the objective to drastically increase waste collection. Urban- rural integration will be piloted there. The experience and lessons learned are expected to inform implementation practices in urban China, much of which is at levels similar to Chongqing. The experience in the demonstration cities will inform the process of developing policy instruments at the central level. This is the first Bank operation in China to tackle rural solid waste management, with the approach of public service delivery to drive for an integrated urban-rural system. This Project has selected two districts in the southwestern municipality of Chongqing to experiment a sustainable model for rural-urban MSW management integration and agricultural mulching plastic collection. Compared with the demand and significance of rural solid waste pollution management in China, the rural component in this project is important but at this stage kept small in view of institutional and operational financing challenges that need to be addressed with project implementation. The Project follows a framework approach for investments in Chongqing. Most urban activities have been identified (first batch of investments, which is the subject of this EIA) while the specific rural activities will be identified during implementation (second batch of investments which is covered in a Preliminary ESMF under separate cover). Urban activities build upon the current system in Chongqing. Rural activities will feed into and link to the urban system such that complementarity is achieved along with efficiency and economies of scale. To that end, rural activities will be designed at a later stage, including related environmental impact and social assessments. The specific rural activities will be included in the project during implementation following appraisal of the feasibility studies for system design in the rural districts, which will be undertaken during implementation. The rural waste management systems will have to ensure full MSW collection and safe treatment/disposal coverage. Selected activities will include collection points and containers, transfer Page 183 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project stations, sorting lines, and local treatment facilities such as small kitchen waste treatment facilities. Permanent closure and remediation of landfills may be supported too if part of the overall system design. If waste will be treated in urban facilities these will not be included in the rural investments under the project. In addition to MSW activities, pilots for agricultural plastic waste collection and handling will be identified during implementation. The activities to be supported will be those that improve the collection and recycling/treatment/disposal of agricultural plastic film. As one of the selected demonstration cities, Chongqing plans to implement the “Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Projectâ€?. Located in the upper reaches of the Yangtze River, Chongqing suffers from frequent rainfall and high risks of garbage flowing into the sea. It is predicted that Chongqing will produce 10.8 million tons of domestic waste and 1.45 million tons of plastic waste by 2035. As a national "Zero Waste City" and one of the first batch of "Compulsory Sorting of Domestic Waste" pilot cities, Chongqing has made many efforts on plastic pollution control of the plastic waste in urban and rural domestic garbage, and carried out a series of work in the whole process from source-control to recycling & reuse, but still suffered from unsound system mechanism, imperfect collection, transfer and treatment system of waste classification etc. The five subprojects under the first batch activities are implemented in such a way to build the waste collection and transportation system and efficient plastic waste resource utilization system according to the principle of "reduction, recycling and disposal after proper treatment", so as to strengthen the comprehensive treatment of urban and rural plastic waste, improve the domestic waste classification, collection, transfer and terminal disposal capacity and whole process management level in Chongqing, minimize the plastic waste pollution, and serve the overall development goals of the World Bank project. Page 184 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 2.1-1 Location of Chongqing in China Chongqing's social and economic construction has basically formed a pattern of coexistence of large-area agriculture, large-output industry, large-density traffic and large-capacity circulation. Chongqing is the largest economic center city in Southwest China and the upper reaches of the Yangtze River. The municipal waste output is on the rise. In 2026, it is estimated that a total of 16,679t/d domestic waste will be generated in the downtown area and the surrounding towns and villages, of which 15,552t/d waste will enter into Chongqing municipal sanitation system, and 16,679t/d recyclable waste will get into the renewable resource system. The urban domestic waste in Chongqing is mainly classified into domestic waste (excluding restaurant waste) and restaurant waste. The proportion of plastic waste is as shown in Figure 3.1-2.

In order to improve the ability of the domestic waste classification supporting system of Chongqing to cope with risks, Chongqing Development and Reform Commission, Chongqing Finance Bureau and World Bank Financed Chongqing Project Management Office jointly implement the "Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Project", strengthen the comprehensive treatment of urban and rural plastic waste, and improve the capacity and management level of domestic waste classification, collection, transfer and end treatment in Chongqing, so to reduce plastic waste pollution and serve the overall development goal of the World Bank project. 2.2 Project description 2.2.1 Project objectives The Project is designed to build an urban-rural plastic waste collection and transportation system, an efficient plastic waste resource utilization system, a Page 186 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project sustainable policy system and a replicable plastic waste management model for reference based on the principles of "reduction, recycling and disposal after proper treatment". It is estimated that, by 2022, the first batch of subprojects under the Project will be completed, when the level of waste recycling in the main urban districts will be effectively promoted. With the transformation of the waste transfer stations in the first batch of subprojects and the construction of Luoqi low-value recyclable utilization base, the plastics recycling, utilization and reuse industry system will take initial shape with the coverage rate of mandatory classification of domestic waste reaches 70% and the plastics recycling, utilization and reuse rate gets 30%. As the completion of Jiguanshi ship waste receiving and treatment project, the water environment of the Yangtze River can be improved significantly. 2.2.2 Project content The first-batch subprojects of the Chongqing Urban-Rural Integrated Plastic Waste Comprehensive Management Project include 3 activity types (as 5 subprojects): 1) Jiguanshi ship waste receiving and treatment project; 2) Luoqi low-value recyclable utilization base project; 3) Function upgrading projects of Jieshi, Xiajiaba and Zouma Waste Transfer Stations. The construction sites, scale and main contents of the subprojects are shown in Table 3.2-1. The specific service areas include Yuzhong District, Jiangbei District, Nan’an District, Jiulongpo District, Shapingba District, Dadukou District, Beibei District, Yubei District, Banan District and Bishan District. The geographical location of the subproject is as shown in the Figure below.

(3) Subproject process â‘  Waste vertical compression process After accessed and weighed, the waste collection truck moves into the unloading hall of the transfer workshop along the ramp, and dumps the waste into the discharge opening, and then into the transfer box placed vertically on the fixed berth of 1F transfer hall. The compactor vertically compacts the waste in the container until the container is fully loaded. Then the transfer vehicle and traction Page 220 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project mechanism take the container out of the berth and pull it on the transfer vehicle horizontally. At last, the transfer vehicle transports the container to the waste treatment plant. Figure 2.3-22 waste vertical compression process â‘¡ Kitchen waste sorting process The kitchen waste is directly poured into the receiving trough and transported to the bag-breaking screening drum through the chain-plate feeder and the lifting- belt conveyor. After the kitchen waste enters the bag-breaking screening machine, the bag breaking knife evenly distributed in the screening drum cuts the waste bag, so that the kitchen waste can be fully graded by particle size in the rotating screening drum. The diameter of the sieve mesh of the drum bag-breaking screening machine is 80 millimeters. The screened waste are classified into two categories: the waste undersize of 80 millimeters and oversize of 80 millimeters. The kitchen waste undersize of 80 millimeters, mainly composed of soil and organic kitchen residues, passes through the sieve mesh. The kitchen waste undersize of 80 millimeters is transported back to the domestic waste discharge tank through the conveyor belt and then into the compression system. The kitchen waste oversize of 80 millimeters contains a relatively large amount of recyclable materials which will enter the winnowing machine through the belt of conveyor. After winnowing, the oversize kitchen waste falls into different conveyor belts and enters the corresponding collection containers respectively, and then enters the photoelectric separation workshop through the conveyor belt for further sorting. Page 221 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Re Non- cyclable recyclabl e process Figure 2.3-23 kitchen waste sorting â‘¢ Recyclable waste sorting process A. Waste plastics sorting process The photoelectric sorting equipment is mainly used in waste plastics sorting process, the intelligent robots assist in sorting waste plastics. The waste plastics are poured into the sorting line and transported by the plate-chain conveyor to the puncture machine and the label remover. The plastic bottles are punctured, flattened and their labels are removed. Then, the waste plastics are evenly sent to the photoelectric sorting machine through the shaking feeder. The transparent PET bottles, variegated PET bottles, transparent HDPE bottles, varicolored HDPE bottles and junk is sorted. The recyclable plastic bottles after classification are sent Man to the associated baler through the conveyor, and intelligent robots are arranged ual to assist in sorting waste plastics to improve the screening efficiency. Junk is collected, packed and then disposed separately. control Page 222 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 2.3-24 waste plastics sorting process B. Waste paper sorting process The waste is manually unpacked and loaded. The more pure waste paper is put into the conveyor and directly packed, and the others are put into the receiving trough. Coarse sorting is performed by OCC. The small-sized and soft miscellaneous paper enters the temporary storage line as the sieve residue, and the large-sized and hard paper boards are discharged as the screen residue, and enter the corresponding manual sorting line. The paper boards after manually sorting out the miscellaneous paper are sent to the packer for packing; miscellaneous paper as the screen residue is discharged to a separate manual sorting line, and the books and newspapers with high recycling value are manually selected and packed. Page 223 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 2.3-25 waste paper sorting process C. Waste metals sorting process The waste are manually unpacked and loaded. Firstly, large waste is put into the metal shearing equipment for shearing.

(Chongqing Government issued [2016] No. 19), all subprojects are located in the Category 2 function zone40. 3.5.2 Functional category of surface water environment The Jiguanshi ship waste receiving and treatment project is located on the right bank of the Yangtze River’s main stream. According to the Notification of Chongqing Municipal People’s Government on Approving Adjustment Scheme of Surface Water Environmental Function Classification in Chongqing, as for the water body function 40 According to the ‘Ambient air quality standard’ (GB 3095-2012), the category II functional areas include residential areas, mixed commercial,traffic and residential areas, cultural areas, industrial areas and rural areas. Page 280 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project classification of the Yangtze River’s Chongqing section, it is required to implement the Category 3 standard while it is within the range related to the downtown area. All subprojects involve neither the surface water intake nor direct wastewater discharge into the surrounding surface water body. 3.5.3 Function regionalization for environmental noise According to the Function Classification Scheme of Acoustic Environment in Main Urban Area of Chongqing, among the 5 subprojects, the Jiguanshi ship waste receiving and treatment project is located in Category 2 function zone of environmental noise41. According to the Chongqing standard, the other subproject sites have not classified with acoustic environment function zones. Therefore, based on the acoustic environment function zone classification method in Technical Specifications for Regionalizing Environmental Noise Function (GB/T 15190-2014), The sites of Jieshi Waste Transfer Station, Xiajiaba Waste Transfer Station, Zouma Waste Transfer Station and Luoqi low-value recyclable utilization base are classified into Category 2 function zone of acoustic environment. 3.5.4 Ecological function regionalization According to the Ecological Function Regionalization of Chongqing (Revised), all subproject sites are located in the areas as “V Artificially regulated ecological area in the metropolitan area – V1 Sub-area of urban ecological regulation in the metropolitan areaâ€?. Zouma Waste Transfer Station and Jiguanshi ship waste receiving and treatment project are located in “V1-1 Ecological function area of urban core ecological restorationâ€?; Jieshi Waste Transfer Station, Xiajiaba Waste Transfer Station and Luoqi low-value recyclable utilization base are located in “V1-2 Ecological function area of ecological regulation of urban peripheryâ€?. In “V1-1 Ecological function area of urban core ecological restorationâ€?, the urban artificial ecosystem and agricultural ecosystem coexist. The dominating directions of ecological function protection and construction include ecological restoration, pollution control, pollution prevention and landscaping. The urban core area is not just the core of ecological restoration in the metropolitan area, but also the key to 41 According to the ‘Acoustic environment quality standard’ (GB 3096 -2008), the category 2 acoustic environment functional zone refers to the area where commercial finance and market trade are the main functions, or where residential, commercial and industrial are mixed, and required to keep the residential areas in quiet condition. Page 281 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project water environment protection of Chongqing City, the Three Gorges Reservoir Region and even the whole upper reaches of Yangtze River. “V1-2 Ecological function area of ecological regulation of urban peripheryâ€? is mainly urban and rural ecotone, where towns and mines are concentrated. The major ecological function of the area is positioned as ecological barrier construction, and the auxiliary functions include water source and water quality protection, nutrient substance maintenance, water conservation and urban landscaping. The protection of water quality for drinking water sources, Yangtze River and Jialing River and pollution control of secondary rivers should be highlighted in this area. The coastal industrial and domestic wastewater should be closed and treated, plus river dredging and comprehensive treatment of river basin, to enhance the regional ecosystem conservation and environmental remediation. The subprojects have no direct impacts on the above ecological functions. The subprojects are designed to improve the environment and minimize the pollution load and discharge, which are in line with the above ecological function classification. 3.6 Assessment scope and factors 3.6.1 Assessment level and scope The ambient air, surface water, groundwater, environmental noise, ecology, soil environment and environmental risk of the 5 subprojects are ranked respectively, and the assessment scope for each factor of each subproject (Table 2.6-1) is identified according to the environmental impact assessment guidelines for each environmental factor of the relevant domestic standards and the World Bank’s Stakeholder Engagement Plan. (1) Atmospheric environment According to Technical guidelines for environmental impact assessment: Atmospheric environment (HJ 2.2-2018), the classification method of assessment work is as follows: Get the project’s main pollutant ratio of maximum surface air mass concentration to standard Pi (‘i’ indicates the i-th pollutant, and the ratio is described as ‘Max concentration ratio to standard’ for short); when Pmax＜1%, the assessment level is 3; when 1%≤Pmax＜10%, the assessment level is 2; and when Pmax≥10%, the assessment level is 1. According to calculation, only Jiguanshi ship waste receiving and treatment subproject’s Pmax＜1% (assessment level 3), and the other subprojects Page 282 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project are all 1%≤Pmax＜10% (assessment level 2). According to the Guideline, the side length of the atmospheric environmental impact assessment scope of level II assessment project is 5 km, and the atmospheric environmental impact assessment scope of level III assessment project does not need to set assessment scope. (2) Surface water environment According to Technical guidelines for environmental impact assessment: Surface water environment (HJ 2.3-2018), the construction project with water pollution is classified by the waste water discharge mode and amount. The construction projects with direct waste water discharge mode are classified as Grade 1, Grade 2 and Grade 3A according to the discharge amount of waste water and pollution equivalent number of water pollutants. The construction projects with indirect discharge mode are classified as Grade 3B, therefore the 5 subprojects are all Grade 3B. Among the subprojects, only Jiguanshi ship waste receiving and treatment project involves water related construction, based on the Guideline, the surface water environment assessment scope is from 500m at the upstream of the proposed dock site to 500m at the downstream. (3) Groundwater environment According to Technical guidelines for environmental impact assessment: Groundwater environment (HJ 610-2016), the assessment level is determined according to the industry classification of construction project and the groundwater environmental sensitivity level, which can be divided into the level 1, 2 and 3. The 5 subprojects’ groundwater environment impact assessment categories are determined according to Annex A, and just Luoqi low-value recyclable utilization base project requires groundwater environment assessment. As the groundwater environmental sensitivity is ‘insensitive’, the assessment work is level 3. According to the Guidelines, the assessment scope is the hydro-geological unit of the project site. (4) Acoustic environment According to Technical guidelines for environmental impact assessment: Acoustic environment (HJ 2.4—2009), if the acoustic environment function zone of the construction project is Category 1 or Category 2 area specified in GB 3096, or the Page 283 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project noise level of sensitive targets within the assessment scope before and after the construction period of the project increases by 3-5 dB (a) [including 5 dB (a)], or the number of people affected by the noise increases greatly, it shall be assessed as level 2. The 5 subprojects’ sites are in Category 2 acoustic function zones, according to prediction, the noise level of sensitive targets within the assessment scopes before and after the construction period of the subprojects increase within 3 dB (a), and no increased population under the noise impact, therefore, the 5 subprojects shall all be assessed as level 2. According to the Guidelines, the assessment scope is the range of 200m out of the site boundary. (5) Ecological environment Based on Technical guidelines for environmental impact assessment: Ecological impact (HJ 19-2011), according to the ecological sensitivity of the affected area and the scope of land (including water area) occupied by the project, including permanent land and temporary land, the ecological impact assessment work is divided into level 1, level 2 and level 3. The 5 subprojects’ affected areas do not involve special ecological sensitive area or important ecological sensitive area, which are ordinary regions with land occupation area ＜2km2, therefore, the assessment level is level 3. According to the Guidelines, the terrestrial ecology assessment scope is the range of 500m out of the site boundary. Considering that the proposed site of the dock is 200m away from the deep-water channel of the river section, and there is frequent disturbance of Jiguanshi anchorage, the aquatic ecological range of the dock is determined as 500m upstream to 500m downstream along the river flow, and transversely about 100m from the river bank to the nearshore boundary of Jiguanshi anchorage. (6) Soil environment Based on Technical guidelines for environmental impact assessment: Soil environment (Trial) (HJ 964—2018), the soil environmental impact assessment is divided as level 1, level 2 and level 3. According to the annex A of the Guidelines, among the 5 subprojects, only Luoqi low-value recyclable utilization base project is a Category 3 project which requires soil environmental impact assessment work. The land occupied by the base is medium-sized, and the soil environmental sensitivity is sensitive (there is arable land around the project). Therefore, according to the soil Page 284 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project environmental impact assessment project category, land occupation scale and sensitivity, the assessment work is classified as level 3. As for Jiguanshi ship waste receiving and treatment project, due to its site close to Xiayaogou Anchorage, in order to correctly judge the anchorage’s impact on the proposed dock site, it is necessary to conduct level 3 soil environment assessment. According to the Guidelines, those subprojects mentioned above are all polluting projects, and their assessment scopes are the range of 50m out of the site boundary. (7) Environmental risk Based on Technical guidelines for construction project environmental risk assessment (HJ 169—2018), according to the hazards of the materials and process systems involved in the construction project and the environmental sensitivity of the place where the project located, combined with the environmental impact approach under the accident situation, the potential environmental hazards of the construction project can be generalized and analyzed, and then the environmental risk potential can be determined according to the Table 2. The risk potential of construction project is classified as rating I, II, III, IV and IV+. Among the subprojects, only Luoqi low-value recyclable utilization base project requires environmental risk assessment, and its environmental risk assessment requires brief analysis as its risk potential is rating I. (8) Downstream and upstream impacts Based on the Environemntal and Social Framework of the World Bank, the potential downstream and upstream impacts related to the sub-projects have been identified. Thesse impacts cause by the facilities or services, not funded as the part of the project, that the subproject rely on to realize its core function s are considered as upstream or downstream impacts. The details are provided in Table 3.6-1.

As the results of caoculation, among the 5 subprojects, besidesJiguanshi ship waste receiving and treatment project’s Pmax < 1% (Grade III), the rest 4 subprojects’ Pmax values are all between 1% and 10% (Grade II). 43 According to ‘Technical guidelines for Environmental Impact Assessment: Surface water Environment’ (HJ 2.3-2018), the assessment grade of construction project with water pollution is classified with its wastewater discharge mode and amount. The construction project with direct discharge of wastewater is divided as Grade I, Grade II and Grade IIIA according to the wastewater discharge amount and the pollution equivalent of water pollutant; the project with indirect discharge of wastewater is classified as Grade IIIB. Therefore, all the 5 subprojects are Grade IIIB.

There is no atmospheric environmental protection target within the plant boundaries of Jiguanshi ship waste receiving and treatment project and Luoqi low-value recyclable utilization base project. The atmospheric environmental quality out of the 50m range from the plant boundaries of Jieshi, Xiajiaba and Zouma waste secondary transfer stations meet the relevant atmospheric environmental quality standards, and within the 50m range from the plant boundaries there is no atmospheric environmental protection target. Therefore, the first-batch subprojects have no atmospheric environmental protection target. This assessment takes the nearest atmospheric impact receptors for typical analysis, and the detailed content is listed in Table 3.7-1.

As for Luoqi low-value recyclable utilization base project, the acoustic environmental quality at 445m from the plant boundary can meet the acoustic environmental quality standard. To be detailed, the acoustic environmental quality at 140m from the plant boundary can meet the relevant standard in daytime, and the acoustic quality at 445m out of the boundary can meet the standard in night. Within the range of 445m out of the plant boundary, there is only 1 acoustic environmental protection target which is away from Luoqi low- value recyclable utilization base’s boundary by 200m. As for Jieshi waste secondary transfer station upgrading project, the acoustic environmental quality at 475m from the plant boundary can meet the acoustic environmental quality standard. To be detailed, the acoustic environmental quality at 150m from the Page 296 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project plant boundary can meet the relevant standard in daytime, and the acoustic quality at 475m out of the boundary can meet the standard in night. Within the range of 475m out of the plant boundary, there are 3 acoustic environmental protection targets which are away from Jieshi waste secondary transfer station’s boundary by 175m, 230m and 300m respectively. About Xiajiaba waste secondary transfer station upgrading project, the acoustic environmental quality at 475m from the plant boundary can meet the acoustic environmental quality standard. To be detailed, the acoustic environmental quality at 150m from the plant boundary can meet the relevant standard in daytime, and the acoustic quality at 475m out of the boundary can meet the standard in night. Within the range of 475m out of the plant boundary, there are 2 acoustic environmental protection targets which are away from Xiajiaba waste secondary transfer station’s boundary by 100m and 120m respectively. And about Zouma waste secondary transfer station upgrading project, the acoustic environmental quality at 475m from the plant boundary can meet the acoustic environmental quality standard. To be detailed, the acoustic environmental quality at 150m from the plant boundary can meet the relevant standard in daytime, and the acoustic quality at 475m out of the boundary can meet the standard in night. Within the range of 475m out of the plant boundary, there are 4 acoustic environmental protection targets which are away from Zouma waste secondary transfer station’s boundary by 85m, 130m, 150m and 300m respectively. The acoustic environmental protection targets are listed in Table 3.7-2.

There is no rare protection animal and plant in the assessment range of terrestrial ecology, so there is no target of terrestrial ecological protection within the assessment scope. Through the data collection, field investigation and data analysis of the aquatic ecological status of Jiguanshi dock, it is found that there are no ecological sensitive areas such as nature reserve within the assessment scope of Jiguanshi dock project, and there are no fish spawning grounds, feeding grounds, wintering grounds and migration channels. There are no fishing records or investigation records of rare and endemic fish in the scope of project assessment, so there is no aquatic ecological protection target Page 298 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project in the scope of project assessment. In addition, because the first-batch subprojects do not discharge wastewater and solid waste to the surrounding environment, there are no surface water and soil environmental protection targets. In conclusion, the first-batch subprojects have 10 environmental protection targets in total, which are all acoustic environmental protection targets without any atmosphere, surface water and soil environmental protection targets. Page 299 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 4 Baseline Data 4.1 Natural environment status 4.1.1 Geographic location Chongqing is a provincial-level administrative region and the only municipality directly under the central government in central and western China.

Its climatic characteristics are manifested in the following four 46: (1) The average annual temperature is higher than that in the eastern region of the same latitude, with high summer temperature and obvious vertical variation of temperature: The average annual temperature in Chongqing is higher than that in the middle and lower reaches of the Yangtze River at the same latitude. The river valleys of the low dam are above 18℃, and 17~18℃ in the elevation of about 400m ASL. The temperature decreases by about 0.58℃ for every 100m increase above 400m. The hottest months are July and August, with an average temperature of 27~29 ℃ , while the coldest month is January, with an average temperature of 6~8℃. The high temperature above 35 ℃ in Chongqing mainly occurs from late July to early September, and there is extreme hot weather over 40℃ from time to time. The vertical variation of air temperature is obvious. 45 Source: Official Website of Chongqing Municipal People’s Government 46 Source: Regionalization of ecological function in Chongqing (revised) Page 300 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (2) Chongqing has abundant rainfall, uneven spatial and temporal distribution, concentrated rainfall time, hot rainy season, and large annual range: the average annual rainfall is 1,000~1,400mm in Chongqing. The precipitation from May to October accounts for more than 70% of the annual rainfall. (3) With many fog days, Chongqing belongs to the areas with low sunshine value compared with the national level: the annual sunshine hours are about 921~1,570 hours, being one of the national sunshine low value areas. Fog weather is another feature of Chongqing. The main season for thick fog is December to February, especially January. (4) Chongqing features complex and changeable weather, and frequent meteorological disasters: drought, flood, wind, hail, high temperature, cold damage, fog damage, snow disaster, debris flow and lightning disaster are often seen. 4.1.3 Landform and topography Chongqing is located in the transition zone between the Qinghai-Tibet Plateau and the middle and lower Yangtze Delta Plain, with large topographic relief. Its terrain slopes progressively downward from south to north along the Yangtze River Valley. As its northwest and central parts are dominated by hills and low mountains, and its southeast part adjoins the Daba Mountain and Wuling Mountain ranges, with many slopes, so Chongqing is widely known as the "Mountain City". The general terrain is high in the southeast and northeast, low in the central and west, and gradually downward from south to north along the Yangtze River Valley. The western elevation ranges generally from 200m to 900m, and the eastern elevation from 1,000 to 2,500m. The service scope of the Project areas includes the downtown area (the 9 districts of the central urban region) and surrounding small and medium-sized towns (Bishan District). With less relief, the central urban area and the Bishan District are mostly low hills and flat dams, at an altitude of below 900m. Karst landform is widely distributed in Chongqing, but mainly concentrated in the eastern part. The Project area mainly covers the downtown area, southern and southeastern areas, so the karst landform is less distributed in the Project area47 . Refer to Figure 4.1-1 for the topographic relief 47 Source: Regionalization of ecological function in Chongqing (revised) Page 301 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project map within the Project location and service scope. Figure 4.1-1 Project location and Topographic Relief Map within the Service Scope 4.1.4 Geology The vast majority of Chongqing Municipality belongs to the first-order tectonic units of Yangtze Paraplatform, and the few parts belong to the Qinling geosynclinal folded system. There are four secondary tectonic units in the area: Sichuan platform depression, Upper Yangtze platform depression, Longmen Mountain - Daba Mountain marginal depression and miogeosynclinal fold system of northern Daba Mountain. The tertiary tectonic units involved in the area are: part of Eastern Sichuan depression-folding bundle and Central Sichuan anteklise; Southeast Sichuan depression-folding bundle; Daba Mountain depression-folding bundle; and part of the southern margin of the miogeosynclinal fold system of northern Page 302 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Daba Mountain. According to the regional geological condition, Chongqing is not located in the seismic zone or in the earthquake-prone area. 48 Refer to Figure 4.1- 2 for the structural outline within the Project location and service scope.

The surface water resources are abundant but difficult for utilization. The trunk stream of the Yangtze River runs from southwest to northeast across the whole territory, with five main tributaries with south-north runoff direction as Jialing River, Qujiang River, Fujiang River, Wujiang River and Daning River and other hundreds of medium or small rivers, to form a radial and asymmetric reticulate 48 Source: Regionalization of ecological function in Chongqing (revised) Page 303 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project water system. There are 374 rivers with a catchment area of more than 50km, 167 rivers with a catchment area of 50~100km, 152 rivers with a catchment area of 100~500km, 19 rivers with a catchment area of 500~1,000km, 18 rivers with a catchment area of 1,000~3,000km and 18 rivers with a catchment area of more than 3,000km. Chongqing boasts abundant surface water resources and extensive development of secondary and tertiary water systems. However, it is difficult to make use of the rivers because of their deep stream trenching, especially the main rivers in the southeast and northeast Chongqing. Surface water accounts for the majority of the total water resources in Chongqing, among which the average annual surface water generated by rainfall is about 56.77 billion cubic meters, and the average annual inflow from the Yangtze River, Jialing River and Wujiang River into Chongqing is about 383.9 billion cubic meters. 49 Refer to Figure 4.1-3 for the drainage map within the Project location and service scope. 49 Source: Regionalization of ecological function in Chongqing (revised) Page 304 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Shan J xi R Z Z i Province enhe D Q Si H Y hong Thouh a M RiveX T ongx M aD M u chuan ouxi W a Ne Y he P i adu H F l ji Provi i a eixiC Xani J Y ir River D n M an N C o Rive ano Rive u i i Qa nce n GR uli n hCree Rive ng Riv ubei inmi D a a axi a g gtz b LDr hex r i ji naF h u g a u Rive r er Pro J H g an Riv L n a oo n o x k River s x e D P a D a i Riv S a u g Hial j Cye n x Lr x n Rive er i vinc ong li X g gt j iZ h nR erR h Ri ich a n ijiu R in n Ci ah s u ongh ji i Y W i gr e tai n R ha x z hi R X R i o giH i u ve q uan g aa i hon n g a on h e R u N g Q i ngs e n i a F Y a R t Rive L a g M e i i g S g n xv exi v X o i X L S i Hunan r Pro Y R n gqi t n a R River g i uofo j S i vR Ri ijia v ho C urn an i a vLegends r ong o Cu g i e eij i R ni n v s o i Province R Service n tg e ng a La RiverR e Rive GR M vin an i y ng g ve eu i R a oncv i W iyv n H e Waste xi h a i n R Rr ia h gt iv gag e h n s i Ship of r a ongei scope cegtzg v a R r r n R ke La G u vProject Ri i v iae ujia n gthe r a an e R within u Low- Transfer r FigureRiv 4.1-3 i The n x Location i iv and ng e riverj system ze e on R g a ji h r the r waste v Service subprojects li n s uizho xi e e ia ve i ke e Scope v a Rinr ng n gr i a value Station er s C e i v v Ri R Ri r i h i R t u receiving e u Rv i u e r e g l Riv a Recyclable Ri r n r r v l veg Riv Ri v y R hr ie R e e ve i ve nev i a i oer n and r According to Chongqing R e Provir Water ResourcesrR r Bulletin R ve eissued (2019) Utilization by Chongqing ve R er u i v ue i r r r vr gbe vn R n gcity had disposal Water Resources r Bureau I in r June 2020, nce in 2019, i the whole r r a a total water Base r i iv supply v i e of 7.64719 vbillion cubic meters, eper capita Rar eRcomprehensive works water e v v g Rii consumption of v245m3, and the water consumption e per RMB n 10,000 yuan of GDP Rk e r i R r i v e r e e R ve (price of the year) e is 32m3.

Within the project area, the total soil erosion area of the central urban area and Bishan District is less distributed and of low intensity. The soil erosion area of Yuzhong District, Jiangbei District, Shapingba District, Nan’an District and Banan District accounts for about 25% of the total area, so the project area is not located in the area with serious soil erosion. 51 Refer to Figure 4.2-1 for the soil erosion within project location and service scope. 50 Source: Regionalization of ecological function in Chongqing (revised) 51 Source: Regionalization of ecological function in Chongqing (revised) Page 306 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 4.2-1 The Project Location and Soil Erosion within the Service Scope 4.2.3 Terrestrial ecosystem Chongqing is diversified in ecosystems, rich in species and complex in structure. The ecosystems in Chongqing mainly include six Grade I ecosystems and more than 20 Grade II ecosystems, such as mountain forest ecosystem, grassland ecosystem, aquatic ecosystem, agricultural complex ecosystem, village/town ecosystem and urban ecosystem. The five subprojects mainly serve the central urban area and the surrounding small and medium-sized towns (Bishan District). After a long period of human development, the ecosystem of this area is mainly composed of urban ecosystem and agricultural complex ecosystem. However, there are still some important ecological sensitive points in the project area, such as nature reserves, forest parks, scenic spots and geoparks. At present, these important ecological sensitive points are identified and marked in Figure 4.1-6. According to the overlay analysis, the five subproject sites do not involve the Page 307 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project ecological sensitive areas and ecological protection red lines, nor the natural habitats and critical habitats.

(1) Terrestrial plant resources In the project-affected area, the common vegetation primarily includes common arbor and scrub-grassland, such as Ficus virens aiton, Broussonetia papyrifera, Humulus scandens (Lour.) Merr. , Imperata cylindrica (L.) Beauv. and Sambucus chinensis Lindl., and other associated common herbs include Youngia japonica, Taraxacum mongolicum Hand.-Mazz., Polygonum lapathifolium L., and Cynodon dactylon (L.) Pers., which are locally common species, without rare or protected Page 308 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project plants or ancient trees and rare trees. (2) Terrestrial animal resource There may be a small number of amphibians and reptiles in the project-affected area, such as bufo gargarizans and zaocys dhumnade; Birds mainly include sparrow, tomtit, egret, etc. There is no large forest in the project-affected area, and the mammals mainly include a small number of rodents, such as sewer rat, mus musculus and other small mammals. There are no rare or protected animals in the project-affected area. 4.2.4 Aquatic ecosystem 52 In the subprojects, only the Jiguanshi ship waste receiving and treatment project will involve water construction and operation. Therefore, this assessment mainly focuses on the investigation and analysis of the aquatic ecological status of this subproject. The river section where Jiguanshi ship waste receiving and treatment project locates is the Yangtze River’s Jiguanshi river section in Nan’an District of Chongqing City, whose main economic function is shipping, without any important ecological functions. According to survey, the dock’s location is away from the National Nature Reserve for rare and Endemic Fish in the upper reaches of the Yangtze River about 55.1km in the upstream direction, and away from the Four Key Fish National Germplasm Resources Reserve about 13.4km in the downstream direction. The ecological sessitive areas are far away from Jiguanshi ship waste receiving and treatment project site in both upstream and downstream directions and beyond the impact scope of Jiguanshi project. Within the assessment scope of Jiguanshi dock project, the ecological sensitive areas such as fish spawning ground, feeding ground, wintering ground and migration channel are not involved. In this assessment, data collection, field investigation, interviews with fishermen and nearby residents, consultation with fish market, fishery experts and fishery departments were conducted on the aquatic ecological status of Jiguanshi dock. Data analysis was carried out, including water quality, plankton, benthos, fish 52 To understand the ecological environmental baseline, local experts and government agency on fishery and environmental protection have been consulted with during the EA process. Page 309 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project resources, etc., and the ecological function of the water area in the assessment area was further analyzed. (1) Plankton â‘  Investigation sample and time period 3 investigation sample sections were set within the aquatic ecological assessment scope for this assessment, and the investigation on plankton were carried out, with duration as from February to April 2021. Figure 4.2-3 Positions of investigation sample points Figure 4.2-4 Field sampling Page 310 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project â‘¡ Investigation method The ecological investigation method of aquatic organisms is based on the ‘Manual for investigation of fishery natural resources in inland waters’ and the ‘Code for water environment monitoring’ (SL219-98). â‘¢ Investigation result A phytoplankton The types and composition of phytoplankton A total of 55 species of phytoplankton, belonging to 32 genera, 6 phyla, 7 classes, 16 orders, were collected in this survey, and they are all local common species (see Table 4.2-2).

Page 328 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project （4）Ecological function analysis Jiguanshi dock is located in the range of Chongqing’s downtown area. In the process of urban development, with the development of land along both sides of the river, human activities have caused serious disturbance to the ecology of this river section. Before the impoundment of the Yangtze River water conservancy project, there were abundant fish resources in this section of the river, which are dominated by benthic life types and riparian fish. After the operation of the dam, the hydrological conditions such as water level, flow velocity, flow rate and water temperature have been largely changed, resulting in significant changes in fish habitat. The flagship species in the Yangtze River represented by Acipenser sinensis, White-flag dolphin, Chinese sturgeon and finless porpoise are "extremely endangered", and some of them have been extinct in the river. The riparian benthic fish originally distributed in this area moved up to the upper reaches of the Yangtze River due to their unadaptability to the changes of hydrological conditions. Artificial propagation and release of common local fish have been carried out many times in the Yangtze River Basin53. According to incomplete statistics, the number of fish released in Chongqing section of the Yangtze River from 2019 to 2020 exceeds 10 million, which changes the composition of fish community in the Yangtze River. At the same time, overfishing of fish by fishermen results in a sharp decrease in the number of fish. The river section has lost its original core ecological function, so, the aquatic ecological assessment area is a ‘modified habitat’. 53 http://www.xinhuanet.com/politics/2016-04/01/c_128854093.htm http://www.shuichan.cc/news_view-382052.html http://nyncw.cq.gov.cn/zwxx_161/qxlb/202012/t20201210_8593984.html https://www.cafs.ac.cn/info/1051/36134.htm Page 329 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project （5）Public consultation During the investigation period of this assessment, the original fishermen, fish markets and residents of the Yangtze River bank were interviewed. In March 2021, the Fishery Department of Nan'an District conducted a interview on the aquatic ecological status of Jiguanshi dock assessment area. The expert consultation on the aquatic ecological status of Jiguanshi dock assessment area and the description of the aquatic ecological status in the assessment report was conducted on April 14, 2021.The consulting expert is Professor Li Yingwen, a senior aquatic ecological expert in Chongqing Common Culture University. His main research direction is the protection of freshwater ecological environment, At the consultation meeting, Professor Li answered the questions encountered by the assessment unit in the assessment process, and pointed out the modification opinions on the description of the current situation of aquatic ecology in the report. At present, the EIA unit has modified and improved the relevant contents. Table 4.2-9 Consultation on current situation of aquatic ecology of Jiguanshi dock project assessment scope SN Object and Method Date Location Feedback and suggestions purpose 1) Main questions for the fishermen: Before the fishermen "landed", what species were the main catches?

After the construction of water conservancy and hydropower projects, the hydrological conditions of water level, velocity, flow rate and water temperature of the river section have been completely modified, which has caused significant changes in habitat. The composition of plankton, benthos and fish were obviously changed, and the flagship species of the Yangtze River are "extremely endangered", some of which have been extinct in the wild. The riparian benthic fish originally distributed in this area moved up to the sections in upper reaches of the Yangtze River due to their unadaptability to the changes of hydrological conditions. Many times of artificial propagation and release of common local fish have been carried Page 332 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project out in the Yangtze River Basin, which has changed the composition of fish community in the Yangtze River. On the other hand, the overfishing of fish by fishermen has resulted in a sharp decrease in the species and quantity of fish resources. Therefore, the aquatic ecological assessment scope is classified as a ‘modified habitat’. 4.3 Socioeconomic status 4.3.1 Basic demographic and economic conditions Chongqing has 38 districts and counties under its jurisdiction, with a total area of 82,400 square kilometers, including 4,800 square kilometers in central urban areas, 77,600 square kilometers in small and medium-sized towns and rural areas. Chongqing had a permanent population of 31,243,200 at the end of 2019, with an urbanization rate of 66.8%. Chongqing has 4 ethnic minority autonomous counties and 1 district enjoying ethnic minority policies under its jurisdiction. They are located in the southeast of Chongqing. They are Shizhu County (79.3% 54 ), Pengshui County (53.85% 55 ), Youyang County (92.3% 56 ), Xiushan County (58.5%57) and Qianjiang District (ethnic minority population is 74.6%58), mainly Tujia and Miao. The permanent ethnic minority population accounts for 5.8% of the total population of the city. The ethnic minority population in the main urban area of Chongqing is nearly 70,000, accounting for about 0.8% of the total population in the main urban area. Among them, the permanent ethnic minority residents are 61,000 (including 31,000 ethnic minority students in colleges), and 54Source: Official Website of Shizhu County Government 55Source: Data from 2010 Census 56Source: 2019 Youyang National Economic and Social Development Statistical Bulletin 57Source: Official Website of Xiushan County Government 58Source: Official Website of Qianjiang District Government Page 333 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project the non-permanent ethnic minority permanent residents are more than 7,000. The five subprojects in the first batch are located in the main urban area, which does not have ethnic minority communities. In 2019, the annual GDP in Chongqing reached RMB 2.36 trillion, and the per capita GDP was RMB 75,828, ranking 9th among the 31 provinces/autonomous regions/municipalities in the country. The per capita disposable income of Chongqing residents was RMB 28,920 per annual, of which the per capita disposable income of urban permanent residents was RMB 37,939 per annual, ranking 11th among the 31 provinces/autonomous regions/municipalities in China; The per capita disposable income of rural residents was RMB 15,133 per annual, ranking 17th among the 31 provinces/autonomous regions/municipalities in China. 4.3.2 Overview of cultural relics in Chongqing By the end of 2019, Chongqing has 445 cultural sites protected at or above the municipal level, including 64 major cultural sites protected at the national level and 381 cultural sites protected at the municipal level. These cultural sites are located in the national or regional development control areas. The special geographical conditions have also given birth to some religious forms and basic beliefs with local characteristics. Such as temples built in the lofty mountains, or simple-structured temples ‘with two stones as the walls, and one stone as the top’ for local earth god. Traditions and customs such as the worship of gods have become a spiritual sustenance of local civilians. At present, such forms are mainly found in rural areas in Chongqing. According to the scene investigation, no tangible cultural heritage was found in the proposed construction site of the 5 subprojects. 4.3.3 Overview of endemic disease/epidemic disease occurrence in the project area Endemic diseases refer to the local and regional diseases which serious endanger Page 334 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project the physical health of the general public. Endemic diseases in Chongqing mainly include endemic fluorine poisoning, iodine deficiency disorders and Keshan disease. Endemic fluorine poisoning is a kind of chronic systemic disease caused by long- term intake of excessive fluorine by local residents through drinking water, food and air, due to excessive fluorine in the local environment, which is mainly characterized by skeletal fluorosis and dental fluorosis. Iodine deficiency disorders are mainly caused by environmental iodine deficiency and insufficient iodine intake by human body, which are commonly found in mountainous areas far away from the coast and with a high altitude. Keshan disease is only found in low-selenium area. Now, no one infected by COVID-19 has been found in the communities around the first-batch subprojects, and there are good medical facilities around the subprojects. 4.4 Current situation of solid waste management in the project area 4.4.1 Output and composition of domestic solid waste in Chongqing According to the Annual Report of Environmental Pollution Prevention and Control of Municipal Solid Waste in Large and Medium-sized Cities in 2019, the output of domestic waste produced by 200 large and medium-sized cities throughout the country in 2018 was 211,473,000 tons. Among them, the output of domestic waste in Chongqing ranked fourth (7.17 million tons), second only to Shanghai, Beijing and Guangzhou. The urban domestic waste collection and transportation system in Chongqing mainly consists of two parts: one part is responsible for collection and transportation of restaurant waste and the other part is responsible for collection and transportation of other domestic waste other than restaurant waste. The data from Chongqing municipal environmental sanitation monitoring center indicates that, among other domestic waste other than restaurant waste, recyclable waste such as plastic cement, paper, textile, wood and bamboo, glass and metal accounts for 41.21%, and plastic waste accounts for 14%; among restaurant waste, plastic waste accounts for 3%. The proportion of plastic waste in the total output of domestic waste in Chongqing is higher than the national average value (12%). Page 335 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 4.4.2 Current situation of main facilities of domestic waste The domestic waste classification in Chongqing is at the preliminary stage, plastic waste and domestic waste are mixed and collected by the same set of waste collection and transportation system, and the collection points of domestic waste are in the charge of each district, county, street and town respectively. As of 2018, in total 1023 waste collection points were established in all districts and countries in Chongqing, including 3,590,000 domestic waste containers and 47,000 kitchen waste containers; 726 waste transfer stations (including 3 classification transfer stations which have been put into use in the main urban area), 2565 domestic waste transfer trucks, and 3265 kitchen waste transfer trucks. In total 7 incineration plants have been put into use and 3 are under construction, 37 landfills have been put into use, 2 are under construction and 11 are out of service. In total 6 kitchen waste treatment plants have been put into use, 1 is under construction and 4 are under commissioning. There are 20~30 plastic waste collection enterprises. At the present stage, the harm-removal treatment methods of domestic waste in Chongqing mainly include incineration and landfill, accounting for about 54% and 45% respectively. 59 At present, Chongqing is in shortage of facilities for waste classification transfer and transportation, and the waste sorting ability of transfer station needs to be improved urgently. Since there is a lack of sorting facilities for plastic waste and there is no independent resource utilization facility for plastic waste, some domestic waste is recycled by private enterprises, and the rest of plastic waste is transported to the domestic waste landfill for landfill and is finally leaked to the environment; The capacity of resource utilization and harm-removal treatment of domestic waste such as recyclable materials, kitchen waste and household hazardous waste is insufficient. 4.5 Environment audit The term Associated Facilities means facilities or activities that are not funded as part of the project and, in the idenfication of the World Bank, are: (a) directly and significantly related to the project; and (b) carried out, or planned to be carried out, contemporaneously with the project; and (c) necessary for the project to be 59 Source: Chongqing Ecological Environment Status Report: 2019 Page 336 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project viable and would not have been constructed, expanded or conducted if the project did not exist. Associated Facilitiesmust meet all three criteria above. As neither upstream nor downstream enterprise/unit of the project meet the definition of associated facilities in the ESF of World Bank after identification, there is no associated facilities in this project. The upstream and downstream enterprises/units of this project ( hereinafter the ancillary facilities ) that have been operated or planned to expand are not necessary for the project’s visibility. Therefore, these enterprises/units are not associated facilities of the project, but ancillary facilities, which include the upstream primary transfer stations, sewage treatment plants, waste incineration plant and restaurant waste treatment plant. The environmental audit on the environmental and social risks and impacts caused by the ancillary facilities is completed, according to the requirements of the World Bank in Environmental and Social Framework.

The transfer station is equipped with 8 integrated deodorization-purification towers, which can provide a removal efficiency of particulate matter, non methane hydrocarbon and odor concentration by 90%. The plant boundary odor concentration can meet the requirements of Emission standard of odor pollutants (GB 14554- 93) and cause an acceptable impact on the surrounding area. The existing waste secondary transfer stations involved in this project as Jieshi, Zouma and Xijiaba have been completed and put into operation. They have already passed the environmental protection acceptance, with effective environmental protection measures. The existing comprehensive building, metering system, surrounding municipal roads, car washing area, etc are all reliable. It is necessary for Jieshi waste secondary transfer station and Zouma waste secondary transfer station to strengthen the management and maintenance against the situation of leachate leakage during the vehicle transportation. The leachate treatment capacity of Jieshi waste transfer station, xiajiaba waste transfer station and zoumaba waste transfer station is 450m3 /d, 180m3 /d and 350m3 /d respectively. Each waste transfer station is equipped with exhaust funnel and integrated deodorization purification tower. The current odor emission meets the standard, and the original odor treatment facilities have high removal efficiency. 4.5.5 Primary transfer station The waste treated by the three subprojects (Jieshi Waste Secondary Transfer Station, Xiajiaba Waste Secondary Transfer Station and Zouma Waste Secondary Transfer Station) of the Project needs to be collected and transferred through the upstream primary transfer stations. The upstream primary transfer stations Page 369 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project spread all over the main urban area and small towns of Chongqing. The transfer scale can meet the requirements of the secondary transfer station, and the sewage is treated by the integrated wastewater treatment facilities for up-to-standard discharge. The solid waste is transferred and treated by a qualified unit, thus providing trustworthiness. See Annex 3 for the specific information on the administrative district, transfer scale and floor area of each transfer station. 4.5.6 Conclusion In November 2020, the Environmental assessment consulting team conducted environmental auditing for the existing secondary transfer stations and the upstream primary transfer stations as well as the some ancillary facilities (Zouma Leyuan sewage treatment plant in Jiulongpo District, Jieshi Group sewage treatment plant in Ba’nan District, Chengbei sewage treatment plant in Yubei District, Jiguanshi sewage treatment plant, Luoqi Town No.2 sewage treatment plant in Yubei District, Luoqi waste incineration plant, Jiangjin Baiguoyuan waste incineration plant, Fengsheng waste incineration plant and Luoqi restaurant waste treatment plant). The audit conclusion is as below: 1) About the 5 sewage treatment plants involved in this project have been put into operation, namely Zouma Leyuan sewage treatment plant in Jiulongpo District of Chongqing City, Jieshi group sewage treatment plant in Ba’nan District, Chengbei sewage treatment plant in Yubei District, Jiguanshi sewage treatment plant in Nan’an District and Luoqi Town No.2 sewage treatment plant in Yubei District. These sewage treatment plants can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place and surfficient treatment capacities capable to meet the sewage discharge demands of the 5 subrpojects of the Project. Therefore, they are reliable enough to be relied on. 2) Among the three waste incineration plants involved in the project, Jiangjin Baiguoyuan waste incineration plant and Fengsheng waste incineration plant have been put into operation, and Luoqi waste incineration plant has been completed and put into trial operation. these waste incineration plants can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place and surfficient treatment capacities capable to meet the disposal demands for other-type waste of the 3 waste secondary transfer stations. So, they are reliable enough to be relied on. Page 370 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project As Luoqi waste incineration plant is in trail operation stage, there is no monitoring data for now. 3) As one of the ancillary facilities involved in the project, Luoqi restaurant waste treatment plant has been put into operation, and can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place. After the phase II expansion, its treatment capacity will fulfill the restaurant waste and kitchen waste treatment demands of the 3 waste secondary transfer stations, therefore the expanded Luoqi restaurant waste treatment plant can be relied on. 4) The existing waste secondary transfer stations involved in the project have been in operation, namely Jieshi waste secondary transfer station, Zouma waste secondary transfer station and Xiajiaba waste secondary transfer station. These waste secondary transfer stations all have passed environmental protection acceptances with environmental protection measures in place. Their existing comprehensive office building, metering system, surrounding municipal roads, car washing area, etc all can be relied on. The transport vehicles of Jieshi and Zouma Waste Secondary Transfer Stations have leachate leakage situations during transportation, which are required to strengthen the management and maintenance. The treatment scales of leachate regulating tanks are 450m3/d of Jieshi waste secondary transfer station, 180m3/d of Xiajiaba waste secondary transfer station and 350m3/d of Zouma waste secondary transfer station. Each transfer station equips with odor treatment facilities such as waste gas exhaust funnel and integrated deodorization and purification tower etc, and with the relatively large treatment scale of the odor treatment facilities, the odor discharge can meet the relevant standards at current stage. 5) Those waste secondary transfer stations’ primary transfer stations are widely dietributed in Chongqing’s downtown area and medium-small sized towns/villages, with sufficient transfer capacity which is capable to meet the demands of the secondary transfer stations. As the sewage is treated by the integrated sewage treatment facility and then discharged after the quality meets the relevant standards, and the soild waste is treated and disposed of by the qualified units, therefore, they can be relied on. In summary, according to the environmental audit, the original existing waste secondary transfer stations and the upstream primary transfer stations as well as Page 371 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project the 9 ancillary facilities can reach the relevant pollutant discharge standards at current stage, with environmental protection measures in place and sufficient treatment capacities basically capable of meeting the demands of this project. And, the feasibility of the project relying on the existing leachate regulating tanks and odor treatment facilities of the existing secondary transfer stations will be demonstrated in Chapter 5. 4.6 Current situation of regional environment quality of the subprojects 4.6.1 Current situation of ambient air quality (1) Current situation of regional ambient air quality According to the data of Ecological Environment Bulletin of Chongqing in 2019 published by Chongqing Ecological Environment Bureau on June 3, 2020, the ambient air quality of the project site in Banan District, Nan’an District, Yubei District, Jiulongpo District is as shown in Table 4.6-1 below.

This is mainly due to the fact that the four districts are all located in the main urban area, and the traffic pollution is relatively large, as well as due to the dust emission from the construction site of urban infrastructure construction and the industrial pollution emission of the industrial park in the urban area. In this regard, Chongqing has formulated the Implementation Plan of Chongqing Carrying out the State Council's Three-year Action Plan to Win the Blue Sky Protection Campaign, for continuously improving the environment air quality.

As for the 72 monitoring sections of the 36 primary tributaries in the reservoir area, the proportion of the sections with nutrient-rich water quality is 25.0%. In 47 monitoring sections of Jialing River Basin, the proportions of sections with Classes I ~ III, Grade IV, Grade V and below Grade V water quality are 72.4%, 149%, 10.6% and 2.1% respectively; The water quality of 21 monitoring sections in the Wujiang River Basin reaches or is better than Grade III. Besides, considering the potential impact of Jiguanshi ship waste receiving and treatment project on the Yangtze River, this assessment has collected surface Page 377 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project water monitoring data of three sections from the Chongqing Environmental Monitoring Center.

Page 392 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5 Environmental Risks and Impacts 5.1 Environmental benefit analysis 1) To promote the plastic waste recycling efficiency and reduce the amount of plastic waste leaking into natural environment by 1000t every year; 2) To promote the recycling rate and utilization rate of recyclable waste, so to reduce the natural resource consumption, mitigate the harm of waste to the environment and improve the sustainable development ability of society; 3) By changing the transportation method as the 2-stage transport mode from the original method of direct vehicle transport from the scarttered front-end garbage stations to waste treatment plants, the average transportation distance from the front-end garbage stations to waste treatment plant will be reduced to 28km from the original 65km. Additionally, after the function upgrading of the 3 waste secondary transfer stations, the garbage transport vehicles will all take the inner ring expressway or the ring expressway, and there will be no need to pass through the urban area. Every day, about 80 garbage transport vehicles are predicted to be reduced from passing through the urban area and towns; 4) To improve Chongqing's capability to cope with the future growth of waste; 5) To promote the overall capability of waste sorting and transfer facilities in Chongqing, enhance the waste sorting capability of Chongqing’s waste transfer stations, and improve the supporting system of domestic waste classification in Chongqing. 5.2 Environmental risks and impacts during the construction period All works in the construction period of the first-batch subprojects involve civil engineering, which will have a certain environmental impact on the surrounding area of the proposed project. The environmental impacts of civil engineering projects are analyzed uniformly due to the similarity during the construction period. 5.2.1 Waste gas The waste gas during the construction period mainly includes the dust generated in the construction process of earthwork excavation, site leveling and material Page 393 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project loading / unloading, the dust and tail gas generated by transport vehicles, and the waste gas generated during the operation of construction machines and tools. The main air pollutants include particulate matter, NOx, SO2 and so on, and emitted in a fugitive manner. (1) Construction dust and transportation dust What has the biggest impact on the ambient air during the construction period is the construction dust, which comes from various fugitive emission sources. The dust generated by site cleaning, earthwork excavation and backfill, and construction material transportation is relatively large, while the dust emission from raw material storage, building structure construction and equipment installation is small. It is planned to use commercial concrete by purchase without setting up on-site concrete mixing units, so there will be no mixing process dust. The impact of the project construction on the surrounding atmospheric environment can be effectively reduced by taking measures such as dust suppression by water spraying. According to the analogy investigation, the particulate matter concentration in the area 40m away from the construction site will be reduced to less than 0.265mg/m3 after taking measures such as dust suppression by water spraying. The nearest sensitive points to the construction site of each subproject are more than 40m of the project site, as shown in Table 5.1-1. Moreover, the vehicle transportation routes will not pass through the sensitive points such as villages and schools after alternative selection. Therefore, the construction dust will have very small impact on the surrounding atmospheric environment and environmental protection targets. Table 5.2-1 Distance from the Nearest Sensitive Point to Each Construction Site Type of Construction site Distance Azimuth sensitive point Jiguanshi ship waste receiving and Residential 102m Southwest treatment project area Luoqi low-value recyclable utilization Residential 200m Southwest base project area Jieshi Waste Transfer Station upgrading Residential 175m North project area Xiajiaba Waste Transfer Station Residential 100m West Page 394 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project upgrading project area Zouma Waste Transfer Station upgrading Residential South 85m project area East The dust generated by vehicle transportation affects the ambient air on both sides of the road. When the road dust is 0.1kg/m2, the influence scope of road dust is about 20~30m, but when the road dust is 0.6kg/m2, the impact scope of vehicle driving can reach 120m~150m. During the construction, water shall be sprayed on the haulage roads 200m outside each construction area and construction site (4-5 times per day), so that the dust in the air can be reduced by more than 70%, thus effectively reducing the impact of dust on the ambient air nearby. The dust generated during the construction period only has temporary impact on the ambient air and will disappear with the completion of construction. (2) Exhaust gas of construction machinery Various fuel construction machinery and transport vehicles will exhaust a certain amount of waste gas during construction and transportation, which contains such main pollutants as NOx and SO2. The oil exhaust gas generated from various power machines during the construction of subprojects will exert certain impact on the local ambient air. However, such impact is temporary and will disappear with the completion of construction. (3) Greenhouse gas The greenhouse gas generated during the construction period of subprojects is characterized by small emission source and disperse and fugitive emission, and mainly generated from the exhaust gas of various construction machinery and vehicles. Since the emission of greenhouse gas (such as CO2 and NOx) is low, there is no need to estimate greenhouse gas emission. 5.2.2 Waste water The waste water generated during the construction period is primary construction waste water and domestic sewage of construction personnel. â‘  Construction waste water The waste water on construction site is mainly flushing waste water of construction machines and transport vehicles, and the estimated amount of waste water is 30m3/d (approximately 6m3/d of each construction site). The pollutant Page 395 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project in the flushing waste water is mainly SS with a concentration of about 1,200mg/L and an output of 36kg/d (approximately 7.2kg/d of each construction site). The flushing waste water of the construction site and machinery will be recycled for dust suppression of the construction site after being pre-treated in the oil separation tank and will not be discharged to the outside. Strict management will be conducted on construction machines to eliminate such phenomena as loss, spill, drip and leakage of mineral oil, so to generally avoid pollution. Therefore, the construction contractor shall strengthen the machinery maintenance during the construction period. â‘¢ Domestic sewage In accordance with the construction of similar projects, the number of construction personnel at the peak construction period is approximately 200 (approximately 40 for each construction site), the daily water consumption at peak construction period is approximately calculated as 20m3/d with the average water consumption of one person in one day as 100L. The amount of water discharge is estimated as 80% of the consumption amount, so the output of domestic sewage of construction sites is approximately 16m3/d. During the construction period, all the project construction personnel shall set construction camps on the construction site, and the domestic sewage shall be collected to the septic tank of each construction camp and then transported by the sewage suction truck to the Wastewater Treatment Plant for treatment. Construction Camp Management Plan is specially prepared for the camps of the Project, including waste water management measures for construction camps. 5.2.3 Noise The noise source generated during the construction period of the subprojects mainly includes construction machinery noise, traffic noise and so on. The construction machines primarily include construction excavator, shovel loader, bulldozer, crane and other high noise equipment. â‘ Noise prediction mode The main noise source at boundary is point sound source. The point sound source mode is adopted for the assessment to predict the impact of the noise source on the environment. Only the attenuation by distance is considered in the prediction, and the maximum noise value under the presupposition that no treatment measure is adopted is taken as the source intensity. The prediction mode is as: Page 396 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Lr = L0 - 20 lg( r / r0 ) In the formula: Lr refers to the sound level at the distance as r to the point sound source, dB (A); L0 refers to the sound level at the distance as r0 to the point sound source, dB(A); r refers to the distance between the prediction point and point sound source, m; r0 refers to the distance between the reference point and the point sound source, m; â‘¡ Prediction result and assessment The Emission Standard of Environment Noise for Boundary of Construction Site (GB12523-2011) is adopted as the assessment standard for analysis and assessment on the construction boundary noise. The impact on the assessment point of concern shall be analyzed and assessed according to the Grade 2 of Environmental Quality Standard for Noise (GB3096-2008). The scope and degree of noise impact of construction machinery can be predicted in accordance with the distance propagation attenuation mode. See Table 5.1-2 for detailed results. Table 5.2-2 Predicted Value of Noise of Various Construction Machinery at Different Distances Unit: dB(A) Distance (m) 5 10 25 50 100 200 400 650 800 Equipment Excavator 88 82 74 68 62 56 50 46 44 Loader 87 81 73 67 61 55 49 45 43 Bulldozer 86 80 72 66 60 54 48 44 42 Crane 87 81 73 67 61 55 49 45 43 Transport vehicle 84 78 70 64 58 52 46 42 40 The prediction results show that the machinery noise generated during the construction period can generally reach the level required by the Emission Standard of Environment Noise for Boundary of Construction Site (GB12523-2011) beyond 50m in the daytime, and reach the standard limit value beyond 250m in the nighttime. Page 397 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project â‘¢Impact analysis on acoustic environmental protection targets As the excavator can produce the maximum noise source intensity among the construction machinery of the subprojects, the impact of excavator on the residents near the construction sites during the operation at boundary will be taken into account. See Table 5.2-3 for the predicted value of construction noise to the environmental protection targets.

Since the WHO noise standards (55/45 dB for residential receptor) mentioned in the EHSGs simply refers to receptor (residential or industrial) without consideration of ambient context of a specific site. While national standards in China provides a five-category practical noise standard for functional zoning with due consideration of different land use contexts. The residential houses in this project is located in a noise function zone of mixed residential and commercial activities, of which the baseline noise level is already 58/48 dB(A). Page 398 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Based on the prediction, the project during the construction period will cause some noise impacts on the residential areas around. In order to mitigate the impact of construction noise, it is recommended according to this EIA to reasonably arrange the construction intensity and properly organize the construction activities, as well as set enclosing wall at the construction site boundary, reduce the devices with high noise or install temporary sound enclosure for the high-noise equipment, keep the construction activity away from the residential area, reasonably design the construction time schedule and adopt other useful measures. According to the experience of similar projects, the noise can be reduced by15 dB(A). Although after the measures are taken, the acoustic environment quality of residential areas can reach the category 2 standard of National Environmental Quality Standards for Noise (GB3096- 2008), . the project implementation unit should actively communicate with the residents. Night-time construction will cause certain impacts on the acoustic environmental protection targets, so it is suggested according to this EIA to forbid night-time construction to reduce the interference to residential areas. Meanwhile, a part of acoustic environmental protection targets distribute along the transportation route during the construction period. It can be seen from Table 5.2-2, that the necessary distance ensuring the transport noise impact can meet the Category II standard is 50m in daytime while 200m in night, so it is predicted that the construction period transport noise will bring some impacts on the acoustic environmental protection targets along the route. This EIA suggests to adopt some measures to reduce such impacts, such as 1) Making sure that the vehicles are normal in running and with necessary licenses; 2) The transport plan is reasonable; 3) Controlling the vehicle speed and whistle. On the basis of those necessary measures being taken, the construction machinery noise has relatively slight impact on the acoustic environmental protection targets. In comparison with the operation period, the construction period may cause temporary impact, and the impact of the construction noise will disappear as the completion of construction. 5.2.4 Solid waste The solid waste generated during the construction period mainly includes construction waste, domestic waste of construction personnel and sludge Page 399 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project generated from excavation of dock basin. â‘  Construction waste The earthwork generated from excavation of subprojects shall be used as backfill materials without spoil. â‘¡ Domestic waste A certain amount of domestic waste will be generated during the construction period. The output of domestic waste generated at the peak construction period is approximately 0.1t/d calculated as per person 0.5kg/day, and that is 45.2t in total. The domestic waste is collected together at a fixed place of the construction site. The domestic waste of the construction sites in Jiguanshi and Luoqi are collected and transported regularly by the municipal sanitation department, and the domestic waste from Jieshi, Zouma and Xiajiaba are transferred and disposed relying on the original waste transfer stations. â‘¢ Sediment Sediment dredged during dock construction will be dried in the mud-dumping yards (2-3 mud-dumping yards are planned to be set at the river bank, with a grit chamner set at the lower part near the mud-dumping yards. After its sediment settled in the grid chamber, the water will be returned to the river. The hydraulic retention time is about 50h. In the construction stage, the operation method of alternatively using the mud-dumping yards will be adopted to avoid the excessively high water level to ensure sufficient sedimentation of the sediment, thus avoiding possible adverse impacts on the quality of river water.) The dried sediment will be used as earthwork for land backfill, and some will be transported to Luoqi landfill. The sediment will exert minimal impact on the environment after being properly treated. The location for the settling basins should be carefully selected based on following criteria: 1. The contractor should carefully design its work site layout within the redline boundary approved by the government; 2. The contractor should ensure the adequate land area for retention time at 50 hours; 3. The settling basin should avoid flooding area and landslide area; Page 400 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 4. The settling basin should near the site with dredging operation; 5. The settling basin should be backfilled immediately after it is closed. 5.2.5 Soil The impact of the construction period on soil is mainly reflected in the following aspects: â‘  Destruction of soil layers and change of soil texture The soil has some stratification characteristics in the formation process, in which the surface layer is humus layer, the middle layer is eluvial deposition layer, and the bottom layer is pedogenic parent material layer. In the process of excavation and backfill, the original soil layers will be disturbed and destroyed, so that the soil of different layers and textures are mixed. During the construction period, the operation procedures of layered excavation, layered stacking and backfilling (bottom soil below and surface soil above) of soil in the pipe trench area should be strictly implemented, which will greatly reduce the change of soil layers and textures. Therefore, the subprojects during the construction period will have minor impact on the soil layers and textures. â‘¡ Impact on the organism in the soil Since the soil layers and textures will be changed during the construction period, the habitat of microorganism, protozoon and mollusk in soil will be changed. Due to no soil organism in the construction ranges of the subprojects, small construction site area and excavation earthwork volume, the ecological equilibrium of the biological amount in the soil will be restored soon. Therefore, the subprojects during the construction period will have minor impact on the organisms in the soil. â‘¢ Impact of waste on soil During the construction period of the subprojects, a certain amount of waste (such as washing waste water, domestic waste, and waste welding materials) will be generated. The waste may contain substances difficult to decompose, and if not properly treated, they will have a certain impact on the soil. During the construction period of the subprojects, the waste is required to be treated in strict accordance with the requirements for waste collection and disposal, so as to avoid the waste entering the soil and causing pollution. Therefore, Page 401 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project the waste generated by the subprojects during the construction period will have acceptable impact on the soil. 5.2.6 Soil and water conservation â‘  Equilibrium of earth-rock The total excavation of the subproject is approximately 7000 m3, mainly composed of excavation of dock basin and flattening construction of the platform field. The total backfill earthwork is approximately 32000m3, mainly composed of backfill of land platform and road embankment. At the current stage of feasibility study, the amount of the soil to be borrowed is very rough and will be updated during the preliminary design. The method that the dredged materials at 6900 m3 will be used on site as much as possible will be adopted. The balance will be provided by the Chongqing City Administration Bureau as there are a lot of construction activities in Chongqing that can provide surplus soil to this subproject. All sources of fill will be subject to physico-chemical testing to ensure they meet quality and geotechnical standards. â‘¡ Predicted water and soil loss In accordance with the survey on the current water and soil loss in the project area, most of the area is water area, idle land and grass land, and there is a small part of slope cropland. According to the terrain, slope, vegetation coverage and other indicators, refering to the soil erosion intensity grading standard and surface erosion grading standard of the Standards for Classification and Gradation of Soil Erosion (SL190-2007), and combining with the expert evaluation method, the background soil erosion degree of the project area is micro erosion with soil erosion modulus of approximately 350t/(km²·a). With the survey analysis on the water and soil loss during the construction period of similar projects in Chongqing, the soil erosion degree during the construction period is strong erosion with soil erosion modulus of approximately 7000t/(km²·a). With the calculation analysis, the disturbance area of the subproject is approximately 2.26hm2, and for the predicted period of 1 year, the potential water and soil loss during the construction period of the subproject is approximately 158t, with the background soil erosion is approximately 8t, and the increased soil erosion is approximately 150t. â‘¢ Scope of prevention and control responsibility and prevention and Page 402 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project control partition The scope of water and soil loss prevention and control responsibility for the subproject is the scope of the project construction area with a total area of approximately 2.26hm2, including the area of land platform and supporting facilities zone of 0.72hm2, area of land connecting road of 0.36hm2 and area of disturbance scope of hydraulic structures of approximately 1.18hm2.

F. Gray, Bermuda grass and so on, which are common species in local area and easy to recover after being affected. Furthermore, the subprojects cover a limited area and hence can only exert limited impact on the terrestrial vegetation and plant resources. The amphibians and reptiles such as Chinese toad and zaocys dhumnade primarily live in the land near water and can get away from the land easily with their strong mobility. The construction noise generated during the construction period will disturb them. However, these amphibians and reptiles will not disappear but go back to the original area after the completion of construction. Therefore, the impact of noise on the amphibians and reptiles is minimal. The birds common in the area such as sparrow, parus major and egret and animals such as sewer rat, mus musculus and other rodents with strong mobility will migrate to the nearby area after being disturbed by the construction noise. Therefore, the project construction will exert minimal impact on birds and animals. â‘¡ Aquatic environment The scope of assessment of Jiguanshi ship waste receiving and treatment project is obviously affected by human activities and belongs to "modified habitat" A. Impact on plankton and benthos During the construction period, the excavation of dock basin and other constructions involving water will cause disturbance to the water body and sediment, thus resulting in concentration rise of suspended solids in the water area, reduction of transparency of the water area in the diffusion range to different degrees, decrease of photosynthetic intensity and quantity of phytoplankton, periodic reduction of water primary production, and accordingly exerting an impact on the species and distribution of zooplankter and reducing the species of zooplankter in the construction area. Therefore, as for the direct or indirect impact of harbor basin excavation on the biomass of plankton, this assessment estimates the biomass loss of plankton during the construction period. By analogy with other water related projects in Chongqing, and according to the construction scale of this project, the impact range of suspended solids on plankton is 200m, the impact depth is about 8m, the impact width is about 30m, Page 404 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project and the loss rate is calculated as 10%. According to the survey, the biomass of phytoplankton is 0.1062mg/L, and that of zooplankton is 0.05774mg/L. The annual reproduction of phytoplankton is calculated as 400 generations, and that of zooplankton is calculated as 30 generations. The underwater construction period is about 120 days. Therefore: The loss of phytoplankton resources is: 200m×8m×30m×0.1062mg/L/1000×10%×400/365×120=67.0kg The loss of zooplankton resources is: 200m×8m×30m×0.05774mg/L/1000×10%×30/365×120=2.7kg Based on the calculation results, the underwater construction will cause slight impact on the plankton in this water area. The impact of suspended solids is mainly in the construction stage, and it is reversible. After the completion of the project, the impact of underwater construction can be gradually eliminated due to the characteristics of many species, large quantity, universal, wide distribution and strong adaptability of plankton. Therefore, due to the self purification capacity of the water body, the species and biomass of plankton will soon return to the original level. B. The impact on benthos The river bed in the construction area will be disturbed by water related construction, and the concentration of local suspended solids will increase, which will have a certain impact on benthos. Yet the excavation area is very small, accounting for 0.30% of the total area of the river section. The biomass loss of benthos during the construction period was estimated in this assessment. According to the design data, the excavation area of No. 1 pier and No. 2 pier is 1230 m2 and 1066 M2 respectively. Based on the survey results, the average biomass (wet weight) of benthos is 4.2g/m2, and the loss rate is set as 70%, so the loss of benthos is: （1230+1066）m2×4.2 g/m2/1000× 70%=6.8kg It is known from the calculation, the underwater construction has slight impact on the benthos of this area. During the construction stage, benthos with strong activity ability will escape after being disturbed, while some benthos with poor activity ability will be buried and died, resulting in slight damage to their number, species and distribution. Page 405 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project However, the above impacts are mainly in the construction stage and are reversible. After the completion of the project, the population of benthos fleeing or near the water area will soon be rebuilt, and their biomass will gradually recover. To sum up, the duration of dredging and water related construction is short, and the influence of suspended solids gradually disappears after the completion of construction. Due to the self purification capacity of the water body and the characteristics of plankton and benthos, such as large species, large quantity, wide distribution and strong adaptability, the original level will be restored soon, which is a reversible impact. The construction of the project has little overall impact on the plankton and benthos in the river section. C. Impact on fishes During the construction period, the impact on fish is primarily reflected in the disturbance of construction machinery noise and vibration and the harm of increase of suspended solids in the water area arising from construction activities. The disturbance of noise and vibration to the fish will expel the fish out of the construction area and manifested as the dispersal effect. Higher content of suspended solids in water will cause accumulation of sediment particles in parotid gland of the fish, and therefore damage the water filtering and respiratory function of gill. There is an obvious link between the content of suspended solids in water and the type of construction ship, water level and water flow rate. In accordance with the analysis on the monitoring data of current condition during the construction period of Yangtze River Waterway Regulation Project, the scope of influence of suspended solids arising from construction is the scope of 150~300m at the downstream of the operating point. Therefore, it is suggested to adopt dredgers with lower sediment resuspension rate for such underwater construction as dock basin excavation and choose the season with lower water level and water flow rate for construction process according to the assessment, so to reduce the diffusion range of suspended solids and ease the impact on fish. Since the short duration of dock basin excavation and water related construction process and the strong mobility of fish, the expelled fish will return to the water area with the completion of construction activities, the project construction will exert slight impact on the fish in the river section. There is no critical habitat of wintering ground, spawning ground and feeding Page 406 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project ground for the fish in the section of the project impact area of the Yangtze River, and the project-affected area is far away from such three grounds for the fish in downstream. 5.3 Environmental Risk and Impact during Operation Period 5.3.1 Waste gas (1) Jiguanshi ship waste receiving and treatment project The cargoes transferred during the operation period of the subproject mainly include ship solid waste, ship sewage, floating waste and so on, and generally no dust generated from loading and unloading process. The energy source of the equipment is electricity. Therefore, there is no oil exhaust gas but ship oil exhaust gas, vehicle exhaust gas, road flying dust and a small amount of foul gas generated during the operation period of the subproject. The subproject may produce a small number of dispersed air pollutants. The ship waste and floating waste will be discharged into the detachable container of garbage truck through the ship’s loading / unloading equipment, and transferred timely. The container of sealed structure has little impact on the atmospheric environment during the loading / unloading and transferring processes. The ship sewage is drawn to the wastewater treatment tank in the back area yard via the sewage pipeline, and then will be discharged into Jiguanshi Wastewater Treatment Plant after being pre-treated. Sealing treatment is conducted in the major process to minimize the impact on the atmospheric environment. (2) Upgrading subprojects of waste transfer stations The waste gas generated during the operation period of the subprojects primarily includes odor generated from the integrated workshop, odor generated from the operation of wastewater treatment facilities, oil fume produced by the dining hall and so on. â‘  Oil fume produced by dining hall The clean energy natural gas adopted in the dining hall of the subprojects will produce oil fume and non-methane hydrocarbon during the cooking and frying process. Because the output of non-methane hydrocarbon is very low and its concentration is less than 10mg/m3, it has no impact on the peripheral Page 407 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project environment. The daily operation time of the dining hall is 2h, 365d/year, and the initial concentration of oil fume is approximately 12~15mg/m3. Each kitchen range is provided with an oil fume purifier with a flow rate of 2000m3/h and purification efficiency of 95%. The purified and degreased oil fume has a concentration of 0.6~0.75mg/m3<1mg/m3, which meets the Emission Standard of Air Pollutants for Catering Industry (DB50/859-2018), and will be drawn through a special oil fume channel to the top of the administration building for discharge, thus exerting a minimal impact on the environment. â‘¡ Odor The survey analysis on constituents of domestic waste shows that the domestic waste contains a lot of organic matters, and these organic matters will produce all kinds of odor pollutants gradually in the fermenting, rotting and decomposing process under the effect of aerobic and anaerobic bacteria. After the reconstruction and expansion of each waste transfer station, the odor will be discharged by the original exhaust funnel which meets the overall engineering odor treatment capacity. The existing exhaust funnels are equipped with an integrated deodorization and purification tower (chemical cleaning + fiber adsorption + biosorption + activated carbon adsorption + ultraviolet disinfection), and the purification device can reduce the concentration of particles, non-methane hydrocarbon and odor by an efficiency of 90%. See Tables 5.3-1~3 for the specific emissions. Based on the original odor removal facilities, the concentration of odor produced by the three waste transfer stations can meet the Emission Standards for Odor Pollutants (GB14554-1993).

(3) Luoqi low-value recyclable utilization base Page 416 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The main air pollutants produced by Luoqi low-value recyclable utilization base during the operation period include non-methane hydrocarbon, odor gas and particles, which are primarily generated from waste plastics melting and cracking. The electric heating mode is adopted for the waste plastic granulate production line to heat the charging barrel. In the hot-melt extrusion process, the direct regeneration mode is adopted without any fire retardant, plasticizer or other additives. The extruding and granulating process is a mere physical melting process. The heating temperature of polyethylene and polypropylene is controlled at about 180-200 ℃ , and the cracking temperature of polyethylene and polypropylene is ≥380℃ and 350℃, respectively. Since the heating temperature is controlled at the degree where no cracking occurs, there is no cracking exhaust gas produced. However, a small amount of exhaust gas, which mainly contains non-methane hydrocarbon (ethylene and propylene), particles and odor, will be produced due to local overheating of the charging barrel in practice. The subproject has three sets of granulate production lines in the production workshop, each of which has a production capacity of 1t/h, daily working time of 24h, annual working time of 365 days and annual production capacity of 8,760t/a. Since three production lines have the same production capacity, the total production capacity of two production lines is 26,280t/a. The plastics melting and cracking production line has a daily oil production of about 54t, and the main products include 10% of gasoline, 85% of diesel oil and 5% of wax oil. The sorted and collected waste plastic is put into a cracking furnace. The external heating mode (operating temperature ≤450℃) is adopted to form an anaerobic micropressure environment in the cracking furnace (under the operating pressure ≤10kPa). At this moment, cracking reaction occurs with waste plastics under the heating effect in the even stirring process. The main gas air pollutants produced from the cracking reaction include non-methane hydrocarbon, particles and odor gas. In addition, a small amount of odor gas will be produced in the waste unloading, unpacking, crushing, sorting and cleaning process, but can be deodorized by the spraying type dust & odor removal system and collected by a gas-collecting hood. Therefore it will exert little impact on the peripheral environment. Production lines of the subproject are equipped with gas-collecting hoods. Since the gas collecting efficiency of the gas-collecting hoods is 95%, there will be still 5% of waste gas discharged in fugitive pattern. See Table 5.3-4 for air pollutants Page 417 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project emission. See Table 5.3-5 for the data of fugitive emission,And please see Table 5.2-6 for air pollutants production and emission.

The fugitive emission of waste gas can reach the applicable standard, and exert slight impact on the peripheral environment. The odor is emitted after treatment by the 35m chimney which is equipped with an integrated deodorization and purification tower (chemical cleaning + fiber adsorption + biosorption + activated carbon adsorption + ultraviolet disinfection), and the purification device can reduce the concentration of particles, non-methane hydrocarbon and odor by an efficiency of 90%. Upon deodorization by the deodorization and purification tower, the waste gas meets the execution standard. According to General EHS Guidelines (HSGs), the chimney height is calculated by Good International Industry Practice (GIIP). HG = H + 1.5L HG -- The suggested flue height of GEP (Good Engineering Practice), with the flue base as the reference level; H --– The elevation of the structure nearby, with the flue base as the reference;14m in this case; L -- The smaller value between the height (h) and width (w) of the structure nearby; 14m in this case; Therefore: HG=35m Therefore, the chimney height of Luoqi low-value recyclable utilization base is 35m. The environmental consulting team has used AERSCREEN model to predict the atmospheric environmental quality of the nearest residential area and the surrounding area of the project, and the prediction results are shown in the table below. Table 5.3-8 Prediction of atmospheric environmental quality around Luoqi low- value recyclable ultilization base Prediction area Maximum The nearest concentration Pollutant resident area Maximum PM10（ãŽ?/㎥） 2.4 4.7 contribution value Page 421 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Attainment 3.4% 6.7% Background value 57 Superposition value 59.4 61.7 Quality limit 70 70 Compliance Yes Yes Maximum 20.4 34.1 contribution value Attainment 1.0% 1.7% Non-methane hydrocarbon（ãŽ?/ Background value 1300 ㎥） Superposition value 1320.4 1334.1 Quality limit 2000 Compliance Yes Yes According to the table above, the distance of the nearest residential point to Luoqi low-value recyclable utilization base’s boundary is 200m, and the predicted concentration values of PM10 and Non methane hydrocarbon are 59.4 ãŽ?/㎥ and 1320.4ãŽ?/㎥ respectively, which are both within the corresponding standard limit values. The maximum concentration point of atmospheric pollutant is at the boundary of Luoqi low-value recyclable utilization base, and the maximum concentration values of PM10 and Non methane hydrocarbon are 61.7ãŽ?/㎥ and 1334.1ãŽ?/㎥ respectively, which are also within the corresponding standard limit values. Therefore, Luoqi low-value recyclable utilization base project’s operation period has minimum impact on the surrounding environment. GHG emission: Luoqi Low-value Recyclable Utilization Base includes three production lines: Waste plastic recycling facilities, Waste glass recycling facilities and Waste textile recycling facilities. The Waste plastic recycling facilities include the waste plastic granulation line and the plastic oil chemical cracking line. According to the equipment data of each waste plastic recycling line, per ton waste plastic recycled, it costs 1110 kWh electricity consumption in Waste plastic granulation line and 542 kWh electricity consumption in the plastic oil chemical cracking line. Moreover, IFI Harmonized Grid Emission factor data set states that the electricity Page 422 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project production process will typically result in 0.944 ton CO2 emission per Megawatt hour generated. the manufacture specific electricity consumption per ton of waste plastic recycling (MWh/t waste plastic) is 1.11 MWh/t waste plastic, then emissions per ton of waste plastic recycling in the case of China = 1.11*0.994 = 1.04784 t CO2/t waste plastic. Therefore, per ton waste plastic recycled, it results in 1.04784 tons CO2 emission in Waste plastic granulation line and 0.574 ton CO2 emission in the plastic oil chemical cracking line. 5.3.2 Waste water (1) Jiguanshi ship waste receiving and treatment project â‘  Waste water source intensity during the operation period The waste water generated during the operation period mainly includes ship domestic sewage and oil polluted sewage, domestic sewage from workers and so on. Ship domestic sewage: the collection volume of ship domestic sewage is 575 m3/d, 189,800m3/a, and the main pollutants are COD, BOD5, SS, ammonia nitrogen, etc. According to Specifications on Environmental Protection Design for Port and Waterway Engineering (JTS 149-2018), the concentration of BOD5 in ship domestic sewage can be calculated with 300mg/L~700mg/L, and the concentration of suspended solids can be calculated with 350mg/L~500mg/L, thus the concentrations of COD, BOD5, SS and ammonia nitrogen in the subproject are 00mg/L, 700 mg/L, 500 mg/L and 35 mg/L. The outputs of the pollutants are 151.8t/a, 132.9 t/a, 94.9 t/a and 6.6 t/a. The ship domestic sewage enters the domestic sewage regulating tank, then enters the integrated wastewater treatment device to reach the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015), and then enters the Jiguanshi Wastewater Treatment Plant for treatment. Ship oil polluted sewage: the collection volume of ship oil polluted sewage is 18m3/d, 6000 m3/a, and the main pollutant is petroleum. According to the specifications, the petroleum content in ship oil polluted sewage is 3,000~6,000mg/L. So the value as 6,000 mg/L is taken in the subproject for calculation, then the output of the pollutant is 36.0t/a. The ship oil polluted sewage is discharged into the ship oil polluted sewage regulating tank for oil- water separation after going ashore, and then transported to Jiguanshi Page 423 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Wastewater Treatment Plant for treatment after reaching the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962- 2015) through the treatment by the integrated wastewater treatment device. Waste oil is collected and stored in a 120L waste oil barrel (with oil tray), and then transferred and treated by a qualified hazardous waste treatment unit on a regular basis. Domestic sewage from workers: the output of domestic sewage from workers is about 2.04 m3/d, 673 m3/a, and the main pollutants are COD, BOD5, SS, ammonia nitrogen, etc. According to the projects with similar process, the concentration values of COD, BOD5, SS and ammonia nitrogen in the domestic sewage from the staff are taken as 350mg/L, 250 mg/L, 250mg/L and 35 mg/L, so the outputs of the pollutants are 0.24t/a, 0.17t/a, 0.02t/a and 0.17t/a. The domestic sewage collected from the staff enters the domestic sewage regulating tank, treated in the integrated wastewater treatment device to meet the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962- 2015), and then it will be treated in Jiguanshi Wastewater Treatment Plant. â‘¡ Impact analysis on waste water discharged into Jiguanshi Wastewater Treatment Plant and impact analysis on surface water environment The waste water of the subproject can reach the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015) after treatment, then enters Jiguanshi Wastewater Treatment Plant for further treatment, and finally it will be discharged after reaching the Grade IA of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). From the perspective of water quality, the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015) can meet the water intake requirement of Jiguanshi Wastewater Treatment Plant, namely, the waste water of the subproject can meet the water requirement for the plant’s water input. Jiguanshi Wastewater Treatment Plant has the designed treatment capacity of 800,000m3/d and the daily average treatment capacity of 722,600m3/d in practice. The waste water discharge after the completion of the dock is expected to be 595m3/d. Therefore, Jiguanshi Wastewater Treatment Plant is fully capable of treating the waste water of the subproject. The change of water quality and quantity before and after Jiguanshi wastewater Page 424 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project treatment plant receiving the dock’s wastewater are predicted in this assessment: A Water quantity Before Jiguanshi wastewater treatment plant receiving the dock’s wastewater, its sewage discharge amount is 8.363m3/s, after that, it receive and treat the wastewater and its sewage discharge amount is 8.370 m3/s, with an increased discharge amount of 0.007 m3/s as the change range of 0.84%, and 0.00004% increase in discharge section. Therefore, after receiving the dock’s wastewater, Jiguanshi wastewater treatment plant’s sewage discharge changes little, which will cause tiny impact on the water quantity of the river section. B Water quality The two-dimensional water quality model of ‘Environmental impact assessment guidelines: surface water environment’ (HJ2.3-2018) is used to predict and calculate the up-to-standard distance and section concentration of each pollution factor before and after being included in the sewage treatment plant. The prediction results are listed below: Table 5.3-9 Prediction of various pollution factors before and after the dock sewage is brought into the treatment plant Pollution Distance to meet Concentration Type factor standard (m) （mg/L） Jiguanshi wastewater treatment plant 6 19.90 COD (original) After the dock’s 6 19.90 sewage added on Jiguanshi wastewater treatment plant 5 3.72 BOD5 (original) After the dock’s 5 3.72 sewage added on Jiguanshi wastewater treatment plant 12 1.00 NH3-N (original) After the dock’s 12 1.00 sewage added on Jiguanshi wastewater treatment plant 219 0.05 Petroleum (original) After the dock’s 219 0.05 sewage added on Page 425 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project According to the above table, the up-to-standard distance and cross-section concentration of each pollution factor are almost the same after Jiguanshi wastewater treatment plant accepts the wastewater from the dock.To sum up, the wastewater from Jiguanshi ship waste receiving and treatment project will not directly enter into the surface water, and the impact on the local surface water environment is very small. The water quality and quantity of Jiguanshi wastewater treatment plant before and after receiving the wastewater from the dock are very small, and the impact on the surface water environment of the river section is negligible. At the same time, Jiguanshi dock should also strengthen the anti- seepage measures of sewage collection tank and other structures, strengthen the maintenance of integrated sewage treatment facilities and air floatation machine and other facilities and equipment, so as to prevent waste water and waste oil from leaking and polluting the environment. (2) Upgrading subprojects of waste transfer stations The waste water produced by the Waste Transfer Stations during the operation period is primarily sourced from the leachate, flushing waste water and domestic sewage generated from the garbage stacking and compacting process. â‘  Leachate Leachate (which is yellowish-brown or taupe) is primarily sourced from the liquid produced in the solid waste stacking and compacting process. It is organic waste water with high concentrated pollutants and complex composition, which can produce volatile gas with strong odor.In the wastewater, the ammonia nitrogen content is large and complex in component. The main pollutants include COD, BOD5, NH3-N, SS and so on. In accordance with the Technical Code for Leachate Treatment of Municipal Solid Waste (CJJ150-2010), the output of leachate of the subprojects shall be calculated by the percentage of 9% of the solid waste quantity in combination with the leachate output of the existing projects and that of other local garbage transfer stations. The information of leachate generated in each waste transfer station is shown in the table. Table 5.3-10 List of Leachate Output of Waste Transfer Stations Waste Transfer Volume of existing Increment of Total volume of Station leachate (t/d) leachate (t/d) leachate (t/d) Page 426 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Xiajiaba Waste 456 42 456 Transfer Station Zouma Waste 496.5 132 496.5 Transfer Station Jieshi Waste 474 96 474 Transfer Station The leachate is treated by the leachate regulating tank, and sent to the Wastewater Treatment Plant for further treatment after reaching Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2008), therefore it has minor impact on the surroundings. The table below shows the details. Table 5.3-11 Leachate Treatment of the Waste Transfer Stations Treatment Total capacity of Waste Wastewater volume of existing Transfer Treatment process Treatment leachate leachate Station Plant (t/d) regulating tank (m3/d) Xiajiaba Chengbei Waste Pretreatement + A/O + MBR Wastewater 456 180 Transfer membrane Treatment Station Plant Zouma Anaerobism + MBR membrane Zouma Waste + two-stage Fenton oxidation Wastewater 496.5 350 Transfer + two-stage biological aerated Treatment Station filter Plant Jieshi Jieshi UASB + MBR + two-stage Waste Wastewater 474 450 Fenton oxidation + biological Transfer Treatment aerated filter Station Plant According to the table above, because the treatment capacity of the original leachate regulating tank at each sewage transfer station cannot meet the total output of the leachate at each waste transfer station after reconstruction and expansion, it is necessary to reconstruct or expand the existing regulating tank or newly build a regulating tank (treatment scale: not less than 510m3/d of Xiajiaba station’s Regulating Tank, not less than 550m3/d of Zouma station’s Regulating Page 427 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Tank, and not less than 530m3/d of Jieshi station’s Regulating Tank). â‘¡ Flushing waste water The flushing waste water primarily includes ground flushing waste water, equipment flushing waste water and transportation vehicles flushing waste water. Where the ground flushing water consumption is calculated as 0.5L/m2 per time, the workshop is flushed for 4 times per day, and the roads and other sites in the station are flushed once per day, the ground flushing water total consumption of the subprojects is 20.97m3/d, and as the discharge is calculated by the percentage of 90% of the water consumption, so the output of ground flushing waste water is approximately 18.88m3/d. The main pollutants include COD, BOD5, NH3-N, SS and so on. The output of equipment and transportation vehicles flushing waste water is approximately 36m3, and the main pollutants include COD, BOD5, NH3-N, SS and so on. The treatment scale of oil separation and sedimentation tank and flushing waste water can meet the production amount of flushing waste water in each waste transfer station after reconstruction and expansion. The oil polluted flushing waste water is treated in the oil separation and sedimentation tank, then discharged together with other flushing waste water into the flushing waste water regulating tank, and then discharged into the municipal pipe network after meeting the Grade III standard under Comprehensive standard on wastewater discharge (GB8978-1996), so it has minor impact on the surroundings. â‘¢ Domestic sewage The domestic sewage primarily includes the common staff domestic sewage and canteen wastewater. In accordance with the Notice on Printing Urban Domestic Water Quota in Chongqing (Revised in 2017) (YS [2018] No. 66), Code for Design of Building Water Supply and Drainage and other provisions, the common domestic water consumption of staffs is 50L/per/day, the coefficient of sewage is 0.9, and the main pollutants include COD, BOD5, NH3-N, SS and so on.

In accordance with the Notice on Printing Urban Domestic Water Quota in Chongqing (Revised in 2017) (YS [2018] No. 66), Code for Design of Building Water Supply and Drainage and other provisions, the common domestic water consumption of staffs is considered as 50L/person*day, and the coefficient of sewage is 0.9, therefore the output is 4,050L/d. The main pollutants include COD, BOD5, NH3-N, SS and so on. In accordance with the Notice on Printing Urban Domestic Water Quota in Chongqing (Revised in 2017) (YS [2018] No. 66), the water consumption of canteen is 25L/person*day, and the coefficient of sewage is 0.9, therefore the output is 2,025L/d. The main pollutants include COD, BOD5, NH3-N, SS, animal and vegetable oils and so on. The sewage from canteen is pre-treated by the oil separation and sedimentation tank, then discharged into the biochemical tank in the plant area for treatment together with the common domestic sewage, and discharged into the municipal sewage pipe network after reaching the Grade III standard under Comprehensive standard on wastewater discharge (GB8978-1996)). So it has minor impact on the surrounding water environment. â‘¢ Chemical waste water The chemical waste water is mainly separated water from gasoline and diesel products and ethylene glycol waste water, with the output of 9.6t/d and 2t/d, respectively. The concentration of ethylene glycol waste water is 1,000mg/L. After pre-treated in the oil separation and sedimentation tank, the separated water of gasoline and diesel products is transported to Luoqi Wastewater Treatment Plant for treatment. Ethylene glycol wastewater is temporarily stored in waste water tank and then treated by a qualified hazardous waste disposal unit. The chemical waste water has minor impact on the surroundings and is not directly discharged into the surrounding water body. Page 431 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5.3.3 Noise (1) Jiguanshi ship waste receiving and treatment project â‘  Noise source intensity The main noise source generated during the operation period of the subproject includes the noise of wastewater treatment equipment, operating noise of ship pollutants transfer equipment, whistle of ship entering and leaving port and transportation noise of vehicles. The ship whistle is temporal noise. The ship pollutants are transferred to the shore through a self-priming sewage pump and the loading / unloading equipment of the ship. The vehicle transportation noise is intermittent movable noise source. The integrated wastewater treatment device has very little impact on the acoustic environment after being laid underground. Therefore, the main typical noise source of the subproject is the mechanical equipment on site, and the noise source intensity is approximately 80dB(A). The details are in the table below.

The prediction is carried out in accordance with the above noise prediction mode and parameters, and the prediction result is as below. The noise emission at boundary of the Jiguanshi ship waste receiving and treatment project shall meet the Category 2 emission standard under the Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008), that is 60dB(A) in the daytime and 50dB(A) in the nighttime. Since the wastewater treatment equipment is mainly arranged in the land area, the boundary prediction is carried out on the land area for the subproject. After such measures as building sound insulation, foundation shock absorption, maintenance service and surrounding greening and noise insulation are taken, with the sound insulation effect as about 20 dB(A). for the table below shows the prediction result of operation noise attenuated to boundary.

After such measures as building sound insulation, foundation shock absorption, maintenance service and surrounding greening and noise insulation are taken, with the sound insulation effect as about 20 dB(A). for the table shows the prediction result: Table 5.3-18 Impact Analysis on the Acoustic Environmental Protection Targets during the Operation Period Backgro Contributi Sound Predicte Standar Prediction calculation und on value insulation d value d value point value (dB(A)) (dB(A)) (dB(A)) (dB(A)) (dB(A)) The Dayti 47.7 20 57 57 60 residential me point 102m away from the project site’s Night 47.7 20 48 48 50 southwest boundary The prediction shows that, after various acoustic environmental protection measures are taken, the noise at the residential point 102m away from the southwest boundary of the subproject in daytime and night can meet the Category Page 434 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 2 standard under the Environmental Quality Standard for Noise (GB3096-2008). Therefore, the noise generated by the subproject during the operation period has acceptable impact on the daily life of the surrounding residents. (2) Upgrading projects of the waste transfer stations â‘  Noise source intensity The noise generated by the subprojects during the operation period is primarily generated from the operation of compressor, crusher, drum screening machine, blower and transfer vehicle, with the noise level of 75~95dB(A). for the table below shows the details of main noise source intensity.

Therefore, the noise generated by the subprojects during the operation period has slight impact on the daily life of the surrounding residents. (3) Luoqi low-value recyclable utilization base project â‘  Noise source intensity The noise generated by the subproject during the operation period is primarily generated from the operation of crusher, drum screening machine, blower and transfer vehicle, and the noise level is 70~95dB(A).

Therefore, the noise generated by the subproject during the operation period has acceptable impact on the daily life of the surrounding residents. 5.3.4 Solid waste (1) Jiguanshi ship waste receiving and treatment project The solid waste generated during the operation period of the subproject primarily include waste oil produced after oil and water separation of ship oil polluted waste water, overhaul waste, ship waste, floating waste, domestic waste produced by workers and sewage treatment tank sludge. A hazardous waste temporary storage room is set in the dock and used to accommodate such hazardous waste as waste oil and oil polluted cotton gloves for centralized treatment by a qualified hazardous waste disposal unit. The ship waste and floating waste with output of about 3,500t/a are discharged into the detachable container of garbage truck through the ship’s loading / unloading equipment, and then transferred timely. The domestic waste from the workers with output of about 3.65t/a is collected Page 439 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project into a waste container and then cleared by the environmental sanitation department on a regular basis. Compared with similar projects, the sludge yield of sewage treatment tank is about 25 t/a, the moisture content is 98%, and the plate and frame filter press with integrated facilities is used for dewatering to 80%,. The sludge is cleaned regularly every quarter and transported by the environmental sanitation company to Luoqi incineration plant for incineration by tanker. The transportation distance is 45km. The sludge is domestic sewage sludge and can be incinerated in the incineration plant. In conclusion, the solid waste produced and collected by the subproject will cause minimal impact on the environment after being properly treated. (2) Upgrading projects of the waste transfer stations The solid waste produced during the operation period of the Waste Transfer Stations mainly includes biochemical pool sludge, waste MBR membrane, waste activated carbon and waste stuffing produced by the deodorization and purification tower, hazardous waste produced in the process of machinery maintenance and so on. The table below shows the generation of solid waste during the operation period of each waste transfer station. Table 5.3-25 List of Solid Waste Produced during the Operation Period of the Waste Transfer Stations Unit: t/a Waste Deodorization and cotton purification device Waste Spent Waste Waste yarn Transfer Sludge activated engine MBR and Chemical Biological membrane Station carbon oil waste stuffing stuffing gloves Xiajiaba Waste 3.5 10.8 2 0.3 0.5 2.5 0.17 Transfer Station Zouma Waste 14 18 4 1.5 0.5 2.5 0.17 Transfer Station Jieshi Waste 6 18 18 0.5 0.5 2.5 0.17 Transfer Page 440 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Station Since the solid waste are hazardous waste other than waste sludge and MBR membrane, improper treatment will cause severe pollution to the peripheral water body and land, so it is required to take further prevention and control measures. The sludge is cleared regularly and delivered to the incineration plant for disposal; the waste activated carbon, waste engine oil, waste cotton yarn and waste gloves are collected and temporarily stored in the temporary hazardous waste storage room in the plant area and delivered to a qualified hazardous waste disposal unit for disposal; the filler for the deodorization and purification device and waste MRB membrane shall be replaced by the equipment manufacture, taken away from the plant area immediately without being stored on site. Furthermore, in the operation period, in addition to disposal the solid waste generated by themselves, the waste transfer stations also have the function of soild waste transferring and sorting. . With its large amount and complex composition, the waste of each transfer station may cause adverse impact on the surrounding environment if it is improperly treated in the transfer and sorting processes, especially for the hazardous waste. The bulky waste is sorted in the sorting workshop, and the recyclable part is treated together with the recyclable waste, while the non-recyclable part is treated with other waste. The other waste is transported to the incineration plant for treatment. The kitchen waste and restaurant waste are sorted in the sorting workshop, and then transported to the restaurant waste treatment plant and the kitchen waste treatment plant for treatment. The recyclable waste is transported to Luoqi low-value recyclable utilization base for recycling. The hazardous waste is collected and temporarily stored in the hazardous waste temporary storage room, and then be handed over to a qualified hazardous waste disposal unit for disposal. See the table for the scale of each waste transfer station. Table 5.3-26 Scale of Each Waste Transfer Station t/d Other Restaurant Bulky Kitchen Recyclable Hazardous waste waste waste waste waste waste Xiajiaba 2600 800 100 1100 460 5 Page 441 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Waste Transfer Station Zouma Waste 3000 800 50 1200 460 5 Transfer Station Jieshi Waste 2600 1000 100 1100 460 5 Transfer Station (3) Luoqi low-value recyclable utilization base project The solid waste produced from Luoqi low-value recyclable utilization base project during the operation period mainly include domestic waste from the staff, restaurant waste, waste residue and a small amount of hazardous waste. A Domestic waste The number of staffs of the subproject is increased by 90 persons. Based on the output of domestic waste per person of 0.5kg/d, the total output of domestic waste is about 45kg/d. The domestic waste is classified and collected at the waste collection point, and then all handed over to the environmental sanitation department for disposal. B Restaurant waste The dining hall is set to provide working meals for the staffs of the subproject. The restaurant waste is calculated as the output of domestic waste per person of 0.35kg/d, so the total output of the domestic waste is about 31.5kg/d. All the restaurant waste is handed over to the environmental sanitation department for disposal. C Waste residue The waste residue generated from the waste plastics recycling facility (waste plastics cleaning and granulating) primarily includes sludge produced by the waste plastics cleaning and granulation wastewater treatment system on a regular basis. The sludge mainly includes waste plastics adhesive substances and waste plastic powder, which is general industrial waste. The cracking residue discharged after the melting reaction of the waste plastics recycling facility (waste plastics Page 442 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project cleaning and granulating) is general solid waste. The waste residue produced by the waste glass recycling facility is primarily obtained by crushing and separating the label paper of the glass bottle. It is general industrial waste too. Waste residues shall be classified and collected in a timely manner and temporarily stored in the general industrial waste storage room of the plant area, and then delivered to the environmental sanitation department for disposal on a regular basis, so to prevent it accidentially leaking into the surrounding soil and water resource. D Hazardous waste Waste activated carbon, 18.75t/a; Waste cotton filter, 2.49t/a. Waste activated carbon and waste filter cotton are collected and temporarily stored in the temporary hazardous waste storage room in the plant area to prevent accidental spills into surrounding soil and water resource, and delivered to a qualified hazardous waste disposal unit for disposal. 5.3.5 Soil The impacts of Luoqi low-value recyclable utilization base project on the soil environment during the operation period mainly include the impact on soil of waste water and solid waste leackage. During the operation period, there is no excavation or backfilling in the subproject, so it will not affect the soil layer and texture, but the compaction of vehicles and the trampling of construction personnel will have little impact on the soil compactness. The waste water mainly includes domestic sewage from staff and the separated water of gasoline and diesel products. If it enters the soil, it may change the pH value of soil, increase the content of organic matter and decrease the water storage capacity. The waste water is not directly discharged into the surroundings. After classification, the domestic wastewater of staff is sent into the plant’s biochemical treatment tank for treatment along with the oil polluted biological sewage which has been pre-treated in the plant’s oil separation and sedimentation tank, and then the mixed sewage will be discharged into the municipal sewage pipeline system after its quality meets the Grade III standard of Comprehensive standard on Wastewater Discharge (GB8978-1996). After pre-treated in the oil separation and sedimentation tank, the separated water of diesel products will be transported to Luoqi Wastewater Treatment Plant for treatment. The solid waste is mainly the cracking residue produced by the cracking of waste plastics. The cracking residue may contain substances that are difficult to Page 443 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project decompose and may cause pollution when entering into soil. The cracking residue shall be timely collected and temporarily stored in the general industrial waste storage room in the plant area, and shall be delivered to the environmental sanitation authority for disposal on a regular basis. The waste water and waste residue during the operation period of the subproject are not directly discharged into the surroundings, therefore it will cause slight impact on the soil environment. 5.3.6 Groundwater There is no centralized drinking water source and special groundwater resource conservation zone in the area where the subproject of Luoqi low-value recyclable utilization base is located. The impact of the subproject during the operation period on groundwater environment is mainly composed of the impact on groundwater of flushing waste water, leachate, domestic sewage from the staff, and a small amount of chemical waste water leakage. If the waste water leaks into groundwater, the concentration of COD, BOD5 and petroleum in groundwater will be increased. The ground of the plant area is sealed and solidified with concrete to prevent seepage, and the permeability is less than 10-7. Anti-seepage measures are taken for flushing workshop, alcoholysis kettle, oil separation and sedimentation tank and waste water tank. The leachate and flushing water can be directly discharged into the municipal sewage pipe network after reaching the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962- 2015). After classification, the domestic wastewater of staff is sent into the plant’s biochemical treatment tank for treatment along with the oil polluted biological sewage which has been pre-treated in the plant’s oil separation and sedimentation tank, and then the mixed sewage will be discharged into the municipal sewage pipeline system after its quality meets the Grade B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015). After pre- treated in the oil separation and sedimentation tank, the separated water of diesel products is transported to Luoqi Wastewater Treatment Plant for treatment. Ethylene glycol wastewater is temporarily stored in waste water tank and then treated by a qualified hazardous waste disposal unit. Luoqi low-value recyclable utilization base project has minor impact on the groundwater environment during the operation period. Page 444 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5.3.7 Ecological impact (1) Jiguanshi ship waste receiving and treatment project A. Terrestrial ecological environment The impact of operation period of the subproject on the terrestrial ecological environment is mainly manifest as the impact of waste gas, waste water, noise and solid waste generated during the operation period on the peripheral environment and organism. As for the Jiguanshi ship waste receiving and treatment project, the waste water produced during the operation period includes oil polluted waste water of ship and domestic sewage of the dock, ships and pontoons. The noise is mainly generated from ship waste receiving and transportation process. The solid waste mainly includes ship waste, waste oil, oily sludge, wastewater treatment device and domestic waste. They will be properly treated after pollution prevention and control measures are taken, and hence will cause no adverse impact on the peripheral vegetation. The birds and small animals which temporarily leave the habitat due to the construction will return to the peripheral area of the subproject gradually. The project operation has minimal impact on these animals since they have adapted to the living environment. In conclusion, the operation period has minimal impact on the terrestrial ecological environment. B. Aquatic environment The impact of operation period on the aquatic environment is mainly manifested as the disturbance caused to the fish activities in the dock area due to the increase of ship entering and exiting frequency and noise. After the subproject is put into operation, there will be only about 5 ships entering the port per day, as the broad water suface around the subproject site, and as the large range of fish activity, thus the project operation has minimal impact on the fish of this river section. The ships in the dock for service and the floating waste collection ships are running within the Chongqing section of the Yangtze River. Therefore, the risk of alien species caused by ballast is not involved in the operation of Jiguanshi ship waste receiving and treatment project. According to the feasibility study report, the riverbed of the river section where the project is located is basically stable, the sediment is in dynamic balance, and there is no cumulative siltation. Therefore, after the operation of the project, there is no need for maintenance dredging. It is suggested that the project should adopt anti leakage pipeline to prevent leakage during the Page 445 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project operation period and affect the water quality. The project is a public welfare project for the centralized treatment of ship pollutants, which is conducive to the ecological environment protection of the Yangtze River. Therefore, the negative impact of project operation on aquatic ecological environment is very small, and there are long-term positive benefits. (2) Upgrading projects of the waste transfer stations and Luoqi low- value recyclable utilization base The impact of operation period of the subprojects on the terrestrial ecological environment is mainly manifest as the impact of waste gas, waste water, noise and solid waste generated during the operation period on the peripheral environment and organism. The waste gas generated during the operation period of upgrading projects of the Waste Transfer Stations and Luoqi low-value recyclable utilization base mainly includes dust generated from various waste and transportation process. The waste water mainly includes domestic sewage and production waste water. The domestic sewage includes staff domestic sewage, bath water and dining hall waste water. The production waste water includes pressing equipment flushing waste water, workshop ground flushing water, vehicle and container cleaning waste water, PET cleaning waste water and leachate generated from the kitchen waste sorting process. The noise is primarily sourced from the blower, diesel generator, crane, crusher and transfer vehicles. The solid waste mainly include biochemical pool sludge, domestic waste produced by workers, scrap metal produced from large-piece waste crushing process, sorted waste, waste stuffing produced by deodorization and purification tower, hazardous waste produced in the process of machinery maintenance and so on. The waste can be properly treated after the pollution prevention and control measures are taken. Therefore, the operation period will cause limited adverse impact on the peripheral vegetation, and the birds and small animals which temporarily leave the habitat due to the construction will return to the peripheral area of the subprojects gradually. The project operation has minimal impact on these animals since they have adapted to the living environment. In conclusion, the operation period has acceptable impact on the terrestrial ecological environment. 5.4 Community health and safety Page 446 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5.4.1 Jiguanshi ship waste receiving and treatment project (1) Construction period The construction duration of Jiguanshi ship waste receiving and treatment project is relatively long, with a construction site (containing a construction camp). There is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 100m. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction workers come from different regions, this may cause the risk of COVID-19 transmission. The workers may have conflict with local residents and commit an illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum degree. During the construction process of Jiguanshi ship waste receiving and treatment project, a large amount of transport vehicles will be increased. According to the analogy, there are about 30 material transport vehicles per day in the construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the expressway as Page 447 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project far as possible without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. The communities around the project site may be exposed to human, chemical and other hazards caused by the project construction. Sometimes, residents may enter the construction site unintentionally or consciously, and thus encounter hazards, including exposure to hazardous substances, contaminated soil and other environmental media, construction buildings, excavation points and building structures (which may lead to the risks such as falling and being trapped). Infectious diseases may also bring certain health threats to the communities near the project site. The health threats brought by the construction site mainly come from the poor health and living conditions, sexually transmitted diseases and infection caused by vectors. At present, the most concerned infectious disease caused by the flow of people in the construction stage is COVID-19. Parts of the construction workers are migrant population, which increases the risk of the spread of the COVID-19. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Jiguanshi ship waste receiving and treatment project is located in the main urban area, there are few communities adjacent to the site. There are about 40 workers in the construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of Jiguanshi ship waste receiving and treatment project during the construction period is very low. (2) Operation period During the operation period, Jiguanshi ship waste receiving and treatment project will cause some community health and safety impacts, which include 1) the harm and risk from dust and odor; 2) the harm and risk from noise; 3) and traffic safety risk. The dust and odor generated in the operation period may affect the surrounding communities. The dust mainly comes from the transport vehicles, and the odor mainly comes from the transported garbage. Thanks to the timely and enclosed waste transport mode, the impacts of dust and odor to the surrounding communities are slight. Page 448 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project A large amount of waste transport vehicles will be increased during the operation period. According to analogy analysis, there will be about 80-100 waste transfer vehicles every day during the operation period. The noise is mainly generated by transfer equipment and transport vehicles. The analysis on the transfer equipment noise has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. As the increase of transport vehicles, the traffic pressure in the surrounding area will be affected, meanwhile, as the awareness of traffic safety in villages and towns is relatively weak, it is possible to cause traffic accidents. During the operation period, the transport vehicles can run through the existing local road as Tanguang Road to get in Yuhang Avenue, then get in the Shijiazhuang Chongqing Expressway through Kaiying Road, and finally reach Fengsheng waste incineration plant. The whole transport route relies on the existing road ways that are mainly fast tracks and expressways, with no needs to newly build transport roads, and without passing through such sensitive points as school, village and hospital, therefore exert minimal impact on the community traffic safety. Both China and Chongqing have comprehensive regulations to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Jiguanshi ship waste receiving and treatment project is located in the main urban area, there are few communities adjacent to the site. The operators of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of Jiguanshi ship waste receiving and treatment project during the operation period is very low. 5.4.2 Upgrading subproject of Jieshi waste transfer station (1) Construction period The construction duration of Jieshi waste transfer station upgrading project is relatively long, with a construction site being set in Jieshi Town, Ba’nan District of Chongqing. Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 175 meters. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. Page 449 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction workers come from different regions, this may cause the risk of COVID-19 transmission. The workers may have conflict with local residents and commit an illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum degree. During the construction process of Jieshi waste transfer station upgrading project, a number of transport vehicles will be increased. According to the analogy, there are about 15 material transport vehicles per day in the construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the expressway as far as possible without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Jieshi waste transfer station is located in the main urban area, there are few communities adjacent to the sites. There are about 40 workers in each construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of upgrading subproject of Jieshi waste transfer station during the construction period is very low. Page 450 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (2) Operation period During the operation period, the community health and safety impacts caused by Jieshi waste secondary transfer station include the following aspects: 1) Physical, chemical and biological harms and risks; 2) Waste leakage risk; 3) Noise harm and risk; 4) Dust and odor harms and risks; 5) Traffic safety risk. The visitors and intruders at Jieshi waste transfer station may face many physical, chemical and biological hazards. Garbage collectors, in particular, often pick up garbage near the waste transfer station, looking for recyclable materials and food residues for raising livestock. These people generally live in surrounding area, with poor living conditions and only the most basic clean and sanitary conditions. These garbage collectors may face many risks, including exposure to human excreta, paper soaked with toxic materials, bottles with chemical residues, metal containers with pesticide and solvent residues, needles and bandages discarded by hospitals (containing pathogenic organisms), and batteries containing heavy metals. The exhaust gas from garbage trucks running to or from the treatment sites and the dust from the treatment operations can cause potential community health risks. Since the transfer, sorting and transportation of waste at Jieshi waste transfer station are conducted in closed mode, waste will not be scattered outside the transfer station. Additionally, a special temporary storage room for household hazardous waste is set up in Jieshi waste transfer station, with strict management system to prevent the visitors and intruders from contacting the household hazardous waste. Therefore, during the operation period, the physical, chemical and biological harms and risks brought by Jieshi waste transfer station to the surrounding communities are slight. There will be a risk of spreading disease if waste leaks outside Jieshi waste transfer station. The garbage leaked outside the waste transfer station through wind, bird foraging and vehicle transportation will not only attract mice, flies and other vectors, but also make the surrounding communities face the impact of harmful substances. Due to the enclosed operation mode of Jieshi waste transfer station’s transfer, sorting and transportation processes, the waste in site will not be scarttered out of the station. So the risk of Jieshi waste transfer station’s waste leakage is mininmal. The noise of Jieshi waste transfer station is mainly generated by transfer equipment and transport vehicles. The analysis on the transfer equipment noise Page 451 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. In addition, after the optimization and comparison of transportation routes, the garbage transfer vehicles will all take the inner ring expressway or ring expressway without passing through schools, villages and hospitals and other sensitive points, so they will cause little noise impacts on the surrounding communities. The dust and odor generated by Jieshi waste transfer station may cause certain impact on the surrounding communities, and the organic dust can also spread pathogenic microorganisms. Due to the enclosed operation mode of Jieshi waste transfer station’s transfer, sorting and transportation, and as the station has set up micro-negative pressure ventilation system, odor gas collection hood, dust suppression & deodorization spray device as well as deodorization & purification tower, its waste gas treatment is up to the standard (please see the content of Section 5.3.1 for the detail). Therefore, the dust and odor harms and risks brought by Jieshi waste transfer station to the surrounding communities are slight. During the operation process of Jieshi waste transfer station upgrading project, a number of transport vehicles will be increased. According to the analogy, there are about 80 waste transport vehicles per day during the operation period, which will have a certain impact on the surrounding traffic pressure.

Although Jieshi waste transfer station is located in the main urban area, there are few communities adjacent to the stations. The operation workers of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of upgrading subproject of Jieshi waste transfer station during the operation period is very low. 5.4.3 Upgrading subproject of Xiajiaba waste transfer station (1) Construction period Page 452 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The construction duration of Xiajiaba waste transfer station upgrading project is relatively long, with a construction site being set in Fangjiashan Village, Shuanglonghu Block, Yubei District of Chongqing. Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 100 meters.

Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 85 meters. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents.

Since the community gathering areas have been avoided in the construction site selection, there is no large community around the construction camp, and all settlements scattered near the boundary of construction camps are located at distances of more than 200 meters. There are about 40 people in the construction camp at the peak of construction. So the construction process has little impact on local public facilities. The provision of the construction site will prosper local economy and increase local employment opportunities, but this will also produce adverse effect on local residents. The domestic waste generated from the construction camp contains pathogenic microorganism, parasitic ovum and breeding mosquitoes and flies, which may cause disease to the workers. The workers will more or less communicate with the local people and might cause the spread of epidemics. Let along the epidemic situation of COVID-19 is still on, as most of the construction Page 459 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project workers come from different regions, this may cause the risk of COVID-19 transmission. The workers may have conflict with local residents and commit an illegal act to impair local public order and safety. The construction personnel may also have poor security awareness, and may bring the risk of electric shock or fire. By establishing a perfect management plan and health system for the construction camp, setting up special person to disinfect the work area every day, ensuring that the construction camp is equipped with enough disinfection materials, measuring the temperature of the staff every day, and executing positive inspection and treatment in case anyone feels discomfortable, the health and safety risks of the construction site to the surrounding communities can be reduced to the minimum degree. During the construction process of Luoqi low-value recyclable utilization base project, a number of construction material transport vehicles will be increased. According to the analogy, there are about 15 material transport vehicles per day in the construction site during the construction period, which will have a certain impact on the surrounding traffic pressure. At the same time, due to the weak awareness of traffic safety in rural areas, it is easy to cause traffic safety accidents. During the construction period, the transport vehicles shall pass through the inner ring and outer ring expressways after transport route optimization without passing through schools, villages and hospitals and other sensitive points, so to ensure the impact on the community traffic safety is minimal. Both China and Chongqing have comprehensive laws to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Luoqi low- value recyclable utilization base project is located in the main urban area, there are few communities adjacent to the site. There are about 40 workers in the construction camp, and the construction camp management plan requires that the construction workers should live in the site camp. The interaction between construction workers and local community is less. Therefore, the GBV risk of Luoqi low-value recyclable utilization base project during the construction period is very low. (2) Operation period During the operation period, the community health and safety impacts caused by Luoqi low-value recyclable utilization base include the following aspects: 1) Oil storage and transportation risks; 2) Chemical storage and transportation risks; 3) Page 460 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Noise harm and risk; 4) Dust and odor harms and risks; 5) Textile safety risk. The operation of Luoqi low-value recyclable utilization base has demands of storage and transportation of diesel and gasoline. Its maximum storage capacity of gasoline is 75.6t and the maximum storage capacity of diesel is 642.6t. In the process of oil storage, there is a risk of leakage and combustion. The influence radius of combustion is 21m, the width of fire dike is 10m, and the distance between the nearest residential area and Luoqi low-value recyclable utilization base is 200 meters. Therefore, the risk of oil storage is very small. See Chapter 5.7 for details. Oils may cause certain hazards to the communities during the transportation process. The transport vehicles will pass through the inner ring and outer ring expressways after transport route optimization without passing through schools, villages and hospitals and other sensitive points, and with strict management system and management measures (please see Section 7.4.2 for the detail), so to ensure the traffic risk brought by oils is minimal. During the operation period, Luoqi low-value recyclable utilization base will use a certain amount of chemicals, including ethylene glycol, methanol and sodium hydroxide. These chemicals may cause some risks on health and safety of surrounding communities during storage and transportation. The usage of ethylene glycol is 0.75t/d, the recovery is 0.7t/d, and the maximum storage is 1.5T; the usage of methanol is 0.25t/d, and the maximum storage is 2.5t; the usage of sodium hydroxide is 0.1t/d, and the maximum storage is 1t. The distance between Luoqi low-value recyclable utilization base and the nearest residential point is 200 meters. The transport vehicles will pass through the inner ring and outer ring expressways without passing through schools, villages and hospitals and other sensitive points, and with strict management system and management measures (please see Section 7.4.2 for the detail), so to ensure the traffic risk brought by chemicals is minimal. The noise of Luoqi low-value recyclable utilization base is mainly generated by the treatment equipment. The analysis on the treatment equipment noise has already been conducted in Section 5.3.3, and it is predicted as a slight impact on the surrounding communities. The dust and odor generated by Luoqi low-value recyclable utilization base may cause certain impact on the surrounding communities, and the organic dust can also spread pathogenic microorganisms. As the base has set up micro-negative pressure ventilation system, odor gas collection hood, dust suppression & Page 461 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project deodorization spray device as well as deodorization & purification tower, its waste gas treatment is up to the standard (please see the content of Section 5.3.1 for the detail). Therefore, the dust and odor harms and risks brought by Luoqi low-value recyclable utilization base to the surrounding communities are slight. Luoqi low-value recyclable utilization base has a certain potential health risk to the consumers who buy the products made of its textiles. In the operation stage of this subproject, the pH value, pesticide, heavy metal, formaldehyde, chlorophenol, chloroorganic carrier and bioactive finishing agent of recycled textiles should be properly tested, and the characteristics of textiles should be evaluated according to the specific conditions of use before entering the market. Both China and Chongqing have comprehensive regulations to avoid GBV risks, and the government has been trying to strengthen law enforcement. Although Luoqi low-value recyclable utilization base is located in the main urban area, there are few communities adjacent to the site. The operators of the new facilities will be employed locally, and the scal of labor inflow is small. Therefore, the GBV risk of Luoqi low-value recyclable utilization base project during the operation period is very low. 5.5 Occupational health and safety 5.5.1 Jiguanshi ship waste receiving and treatment subproject (1) Construction period Jiguanshi ship waste receiving and treatment project has some occupational health and safety risks during the construction period, mainly including (1) risks of human body hazards (such as human body being trapped, caught or impacted by mechanical parts, working at height, hearing damage caused by noise, electric shock, high-temperature operation, damage to vision caused by welding); (2) chemical hazards (risks of workers' respiratory tract irritation, discomfort and illness caused by poor air quality, property loss, injury or death of staff caused by fire, etc.); (3) drowning hazard. Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Therefore, the risk rating of the impact from Jiguanshi ship waste receiving and Page 462 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project treatment project’s construction period to the occupational health and safety of the staff is ‘Substantial’. (2) Operation period The Jiguanshi ship waste receiving and treatment project involves high temperature operation, drowning and other hazards. The workers will frequently contact the waste (including hazardous waste) with odor, which contains toxic and hazardous substances, a large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches. The odor will cause adverse impact on the breathing, blood and digestive system. The large number of bacteria and eggs or larvas of mosquitoes, flies and cockroaches may cause disease. Thus, the rating of the impact of Jiguanshi ship waste receiving and treatment subproject’s operation period on the occupational safety and health is ’Substantial’. 5.5.2 Jieshi waste transfer station upgrading subproject (1) Construction period The daily waste treatment capacity of Jieshi Waste Secondary Transfer Station is 4,630 tons. During the reconstruction period, the working units of Jieshi Waste Secondary Transfer Station will not be all shut down (about 25% of the units will be shut down due to the construction process). In order to meet the demand of daily waste transfer capacity, this will have certain impact on other working units. First, the work intensity of the remaining units will increase. Second, the working hours of the remaining units will increase as well. Long term work with high intensity and long operation hours will also affect the physical and mental health of the staffs, making their immunity get weakened and more vulnerable to the bacteria in the waste, so to lead to a growing risk of illness. Long-time work will also bring certain damage to mechanical equipment, for example, the lack of timely maintenance will increase the risk probability of safety accidents. In addition, there are other occupational health and safety risks during the construction period of the subproject, mainly including (1) risks of human body hazards (such as human body being trapped, caught or impacted by mechanical parts, working at height, hearing damage caused by noise, electric shock, high-temperature operation, damage to vision caused by welding); (2) chemical hazards (risks of workers' respiratory tract irritation, discomfort and illness caused by poor air Page 463 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project quality, property loss, injury or death of staff caused by fire, etc.). Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Jieshi waste transfer station will continue to operate in parallel with the improvement construction project, which will increase the life and fire safety risk of Jieshi waste transfer station. Some mitigation measures need to be taken to reduce life and fire safety risk, such as the separation of construction area and operation area. Therefore, the risk rating of the impact from Jieshi waste transfer station upgrading project’s construction period to the occupational health and safety of the staff is ‘Substantial’. (2) Operation period The workers will work in confined space during working hours, and be exposed to noise, mechanical and chemical damage.

Page 465 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5.5.4 Zouma waste transfer station upgrading subproject (1) Construction period The daily waste treatment capacity of Zouma Waste Secondary Transfer Station is 3,890 tons. During the reconstruction period, the working units of Zouma Waste Secondary Transfer Station will not be all shut down (about 25% of the units will be shut down due to the construction process).

Since COVID-19 outbreak is not ended yet and most construction personnel come from other places, they may bring the risk of the spread of COVID-19 during the construction period. Therefore, the risk rating of the impact from Luoqi low-value recyclable utilization base project’s construction period to the occupational health and safety of the staff is ‘Substantial’. (2) Operation period The workers will work in high temperature condition or confined space during working hours, and be exposed to noise, mechanical and chemical damage. In addition, Luoqi project involves high pressure amd temperature risk, toxic and harmful substances (diesel oil, gasoline) and chemicals (methanol, ethylene glycol). Exposure to diesel oil and gasoline may have adverse effects on nervous system, respiratory tract and skin; exposure to methanol may have adverse effects Page 467 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project on nervous system and visceral organs; exposure to ethylene glycol may have adverse effects on digestive tract, respiratory tract and nervous system; in addition, diesel oil, gasoline and methanol may have combustion risks. Thus, the rating of the impact of Luoqi low-value recyclable utilization base’s operation period on the occupational safety and health is ’Substantial’. 5.6 Cultural heritage According to the field investigation and stakeholder engagement, there is no tangible cultural heritage within the impact scope of the first-batch subprojects. 5.7 Environmental risk analysis The site of Jiguanshi ship waste receiving and treatment project is close to the Xiayaogou anchorage. During the construction and operation periods, there may be some environmental risks of water body pollution due to diesel oil leakage from damaged oil bunker caused by collision of ships entering and leaving the port. The Luoqi low value recycling base also has environmental risk at some degree as it involves oil storage and use of methanol. 5.7.1 Risk of oil spill According to the feasibility study report of the Jiguanshi ship waste receiving and treatment project, the site is close to the Xiayaogou anchorage. There is a small overlap between the turning water area of the proposed No.2 ship waste receiving pier and the anchorage, with the nearest distance of about 64M. It is known from investigation that the Xiayaogou anchorage is a temporary anchorage which is in a relocation plan of the administrative departments, and the planned relocation time is about 2021. During the construction period of the Jiguanshi ship waste receiving and treatment project, there will be a small amount of construction vessels all in the water area near the dock. As they are still in a distance from the anchorage, their impacts on the anchorage are relatively slight. As the increase of inbound and outbound vessels during the operation period, they may collide with the ships of the anchorage. However, as there are only about 5 vessels entering the port every day, the probability of collision is very low. The occurrence of ship traffic accidents is related to the geographical conditions, meteorological conditions, hydrological conditions, ship density and the quality of Page 468 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project ship drivers and managers. As the completion of the subproject, it is recommended for the construction units to formulate and execute the emergency prevention measures for accidents from the aspects below: 1) In order to ensure the navigation safety of the ships near the dock, within the jurisdiction of the MSA, the dock owner shall accept the coordination, supervision and management of the MSA to the ships 2) Strengthening the management on ship traffic order in the waterway. In order to avoid the pollution caused by ship collision in the waterway, the Port and Waterway Bureau shall strengthen the management on ship traffic order in the water channel and grasp the dynamic situation of ships entering and leaving the channel in time. 3) Necessary safety guarantee facilities such as navigation guidance / navigation aids shall be set up in the area near the dock. The vessels entering the port must display signals in accordance with the regulations on signal management of the Ministry of communications. The owner of the dock is required to improve the management on ships safety dispatch, reasonably arrange the vessels’ berthing time, departure time and navigation channel during the operation period, so to avoid collision accidents. 4) Formulate strict dock task system and operation procedures to prevent possible accidents. 5) In case of emergency, it is required to take necessary measures immediately, and meanwhile report to the water accident emergency rescue center and the relevant units. 6) The emergency equipments shall be prepared in accordance with the requirements of ‘Requirements on preparedness capabilities to pollution incidents at waters for ports and docks’ (JT / T 451-2017) which are listed in the table below. Table 5.7-1 Requirement of emergency equipment for oil spill on water Equipment Equipment name Unit Number specification Oil absorbing material Ton 2 Oil boom Emergency type m 300 Page 469 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Oil collector (20m3/h) Unit 1 Oil trawl 4m3 Set 2 Oil boom deployment boat Unit 1 Storage device m3 20 5.7.2 Oil storage The daily output of oil is 54t, of which 10% is gasoline, 85% is diesel oil, and 5% is wax oil. Wax oil is not a hazardous environmental risk substance, so it is not analyzed. Diesel oil and gasoline leaking to the soil will mainly pollute the plants growing in the soil, inhibit the growth of plants, and affect the absorption of nutrients by the plants; diesel oil and gasoline leaking to the surrounding water body will cover the water surface. Due to surface tension, a large area of coverage will be formed to isolate the water from the air. The air cannot dissolve into the water, resulting in severe lack of oxygen in the water, fish death, and decreased transparency. Due to lack of sunlight, the algae die quickly, and the fish and algae decay and pollute the water body. Diesel oil and gasoline volatilized into the air may cause the workers' chronic poisoning after long-term inhalation of high-concentration diesel oil and gasoline vapors, such as dizziness, headache, palpitations, weakness, nausea, vomiting, blurred vision, tingling sensation, irritability, unsteady gait, transient loss of consciousness and symptoms of upper respiratory tract irritation. As the nearest residential area is 409m from Luoqi Low-value Recyclable Utilization Base, the diesel oil and gasoline vapor will not be diffused to it, and this will not produce impact on surrounding residents. The tank farm is of 20m×20m scale with one gasoline storage tank(200m3) and two diesel storage tanks(500m3). The oils are transported away every two weeks, so the maximum storage capacity of gasoline and diesel oil is 75.6t and 642.6t, respectively. In accordance with the Technical Guidelines for Environmental Risk Assessment on Projects (HJ 169-2018), the threshold storage quantities of gasoline and diesel oil are both2,500t. Q = q1 / Q1 + q2 / Q2 q1,q2 ——Maximum storage capacity of diesel oil and gasoline Page 470 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Q1, Q2 ——Threshold storage quantity of diesel oil and gasoline Result: Q=0.29 <1 Therefore, the oil storage will result in low environmental risk that can be controlled to the acceptable level by strengthening management and introducing the risk reduction measures. 5.7.3 Methanol A certain storage capacity of methanol, as the raw material used in Luoqi low- value recyclable utilization base, will be provided. Methanol is easy to volatilize, and after inhalation of a large amount of methanol in a short time, the workers will present mild eye and upper respiratory tract irritation symptoms (gastrointestinal tract irritation symptoms after oral administration), headache, dizziness, fatigue, drunkenness, and hazy consciousness after a period of latent period; as the nearest residential area is 409m from Luoqi low-value recyclable utilization base, the methanol vapor will not be diffused to it, and this will not produce impact on surrounding residents. The daily consumption of methanol is about 0.25t, and the maximum storage capacity of methanol is 2.5t for 10 days of consumption. In accordance with the Technical Guidelines for Environmental Risk Assessment on Projects (HJ 169-2018), the threshold storage quantity of methanol is 10t. Q = q1 / Q1 q1 ——Maximum storage capacity of methanol Q1 ——Threshold storage quantity of methanol Result: Q=0.25 <1 Therefore, the methanol, as the raw materials for the subproject, will result in low environmental risk that can be controlled to the acceptable level by strengthening management and introducing the risk reduction measures. 5.8 Safety risk assessment At the site, storage of waste plastics, the oil products (gasoline and diesel), and the chemical materials (methanol ) are located in line with the regulation for fire prevention of China, as shown in Figure 5.8-1 below. Page 471 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Figure 5.8-1 Luoqi Low-value Recycling Base project layout plan The above figure is the layout plan of Luoqi Low-value Recycling Base project. Area 1 is tank farm for gasoline and diesel. The storage of gasoline is 40 meters from the storage of diesel. Area 4 is temporary storage of waste plastics. Area 12 is the chemical storage area, where methanol is stored. The distance between area 1 and area 4 is 88 meters, and the distance between area 4 and area 12 is 126 meters. 5.8.1 Oil storage Luoqi low-value recyclable utilization base of the Project will produce oils with the daily output of 54t, including 10% of gasoline, 85% of diesel oil and 5% of wax oil. The wax oil has a high ignition point and flash point with low output. This safety risk analysis only involves gasoline and diesel oil, since the leakage of diesel oil and gasoline will cause a fire safety risk. The oils are transported away every two weeks in Luoqi low-value recyclable utilization base, so the maximum storage capacity of gasoline and diesel oil is 75.6t and 642.6t, respectively. In accordance with the Identification of Major Hazard Installations for Hazardous Chemicals (GB18218-2018), the threshold quantity of gasoline and diesel oil is 200t and 1,000t, respectively.

Pool fire model prediction: The mathematical model analysis method of pool fire accident consequences is applied to determine the degree of fire hazard impact. As the gasoline storage tank is 200m3, and the diesel storage tank is 2×500m3, the fire dike is 80m in length, 10m in width and 1.5 m in height. Once the tank body is broken, the liquid will spread along the ground and will flow to the fire dike to form a liquid pool.

Therefore, the area beyond 16 meters away from the fire dike is safe. Figure 5.8-1 Tank Farm safty distance As the figure above shows, the distance between the fire dike and the nearest affected target is 17 meters. Therefore, the oil storage will not cause great damage Page 475 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project to staff and facilities. The distance from the fire dike to the nearest resident is 200 meters. As a result, the fire accident of the tank farm will not cause damage to surrounding communities. 5.8.2 Methanol storage A certain storage capacity of methanol, as the raw material used in Luoqi low- value recyclable utilization base, will be provided. Methanol is easy to volatilize, and can generate explosive mixture when mixing with air. It will cause a risk of burning and explosion after exposure to heat and open flames. The daily consumption of methanol is about 0.25t, and the maximum storage capacity of methanol is 2.5t for 10 days of consumption. In accordance with the Identification of Major Hazard Installations for Hazardous Chemicals (GB18218- 2018), the threshold quantity of methanol is 500t. Hazard installation classification: R = ï?¡ * ï?¢ 1 * q1 / Q1 R ——Classification index of major hazard installations α ——Correction coefficient of exposed personnel, taken as 2 β1 ——Correction coefficient of methanol, taken as 2 q1 ——Maximum storage capacity of methanol Q1 ——Threshold quantity of methanol Result R=0.02 The corresponding relation between the level of major hazard installations and R value is shown in the table below.

Explosion model prediction: Shock wave overpressure generated by methanol explosion is its main hazard. The traditional TNT equivalent coefficient method is applied in this model to simulate and calculate the shock wave overpressure, and predict the severity of the methanol explosion.

Table 5.8-4 Extent of Harm to Human Body Caused by Explosion Harm radius m Consequence of harm 0≤R≤3 Death 318 Safe According to the table above, the lethal radius of methanol is 3m, and the serious injury radius is 9m. It is necessary to keep the staff dormitory and production workshop from the methanol storage room at a safe distance of more than 9m, and hazard warning signs shall be posted. The methanol storage room is 200 meters away from the nearest residential area. Therefore, the methanol explosion will not cause huge harm to the staff or damage to equipment and surrounding communities. 5.8.3 Temporary storage of waste plastics During the implementation and operation of the first five subprojects of the Project, the plastic waste will be transported at a capacity of 145t/d, and the maximum temporary storage of plastic waste is 50t. The investigation shows that the plastic waste contains water, and is transported in a fully confined space without open fire. Deodorant spray, which contains water, will be used to deodorize the Waste Transfer Stations and Luoqi low-value recyclable utilization base, and the plastic waste will be broken with water during the sorting process. There is still fire risk in the Project. When each subproject is operating, well- established fire-fighting measures shall be developed for each subproject, including providing sufficient fire equipment and conducting fire education to workers. 5.9 Cleaner production Page 478 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 5.9.1 Energy saving evaluation (1) Jiguanshi ship waste receiving and treatment project The energy consumption types of the energy consumption system and main energy consuming equipment of the subproject are electric power, fuel oil consumed by some mobile machinery and tap water consumed as production water and domestic water in dock area. The consumption of electric energy is 630 kW·h/a, converted into 774.27 tce of coal equivalent; and the water energy consumption is 6,171t, converted into 528.85 tce of coal equivalent. According to the transportation industry standard of the People's Republic of China - Evaluation on Comparable Design Unit Energy Consumption for Loading and Unloading Production in Port Fixed Assets Investment Project (JT/T 491-2014), the Grade I standard of comprehensive comparable energy consumption in the design of loading and unloading production of liquid bulk cargo dock is 0.05t of coal equivalent/10,000t of throughput, and the Grade I standard of comprehensive energy consumption of loading and unloading production design of miscellaneous cargo dock is 3.6t of coal equivalent/10,000t of throughput. The assessment requires that the energy consumption level must be considered in the equipment selection of the subproject, and shall meet the national energy consumption standard. The comprehensive unit consumption of comparable energy in the loading and unloading production design of the subproject can reach the Grade I national standard, which will not have a negative impact on the energy consumption intensity of Nan’an District and Chongqing City during the "14th Five-Year Plan", therefore the impact is relatively small. (2) Luoqi low-value recyclable utilization base Electricity is the main energy consumption of Luoqi low-value recyclable utilization base. The power consumption is 726.52*104kW·h/a, converted into 893.6196 tce of coal equivalent. The assessment requires that the energy consumption level must be considered in the equipment type selection for the subproject, and shall meet the national energy consumption standard. The energy consumption of the subproject only accounts for a low percentage of the total social energy consumption in Yubei District and Chongqing City, and will not cause negative impact on the energy consumption intensity in Yubei District and Chongqing City during the "14th Five-Year Plan", so its impact is limited. Page 479 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project (3) Upgrading project of Jieshi Waste Transfer Station The main energy of the upgrading project of Jieshi Waste Transfer Station is electricity and diesel oil, and the power consumption is 531.46*104kW·h/a, converted into 653.70 tce of coal equivalent; the diesel oil consumption is 2,867.82 t/a, converted into 4,178.7 tce of coal equivalent. The assessment requires that the energy consumption level must be considered in the equipment type selection for the subproject, and shall meet the national energy consumption standard. The energy consumption of the subproject only accounts for a low percentage of the total social energy consumption in Ba'nan District and Chongqing City, and will not cause negative impact on the energy consumption intensity in Ba'nan District and Chongqing City during the "14th Five-Year Plan", so its impact is limited. (4) Upgrading project of Xiajiaba Waste Transfer Station The main energy of the upgrading project of Xiajiaba Waste Transfer Station is electricity and diesel oil, and the power consumption is 531.46*104kW·h/a, converted into 653.70 tce of coal equivalent; the diesel oil consumption is 2,867.82 t/a, converted into 4,178.7 tce of coal equivalent. The assessment requires that the energy consumption level must be considered in the equipment type selection for the subproject, and shall meet the national energy consumption standard. The energy consumption of the subproject only accounts for a low percentage of the total social energy consumption in Yubei District and Chongqing City, and will not cause negative impact on the energy consumption intensity in Yubei District and Chongqing City during the "14th Five-Year Plan", so its impact is limited. (5) Upgrading project of Zouma Waste Transfer Station The main energy of the function upgrading works of Zouma Waste Transfer Station is electricity and diesel oil, and the power consumption is 195.2*104kW·h/a, converted into 240.10 tce of coal equivalent; the diesel oil consumption is 796.62 t/a, converted into 1,160.75 tce of coal equivalent. The assessment requires that the energy consumption level must be considered in the equipment type selection of the subproject, and shall meet the national energy consumption standard. The energy consumption of the subproject only accounts for a low percentage of the total social energy consumption in High-tech Zone and Chongqing City, and will not cause negative impact on the energy consumption intensity in High-tech Zone and Chongqing City during the "14th Five-Year Plan", Page 480 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project so its impact is limited. 5.9.2 Water saving evaluation The first-batch subprojects’ area is rich in water resources and is not a water- deficient area. As the water demand of the first-batch subprojects is very low, the water use will not affect the local water supply, and will not cause pressure on the local water resources. Therefore, the first-batch subprojects have little impact on local water use. The water demand of all subprojects is shown in the table below. Table 5.9-1 Water Demand of All Subprojects Jiguanshi Luoqi low- Xiajiaba Zouma Project name Jieshi Waste ship waste value Waste Waste Transfer receiving recyclable Transfer Transfer Station Water and utilization Station Station upgrading consumption treatment base upgrading upgrading project project project project project Water consumption 6171 14.6*104 9.58*104 9.58*104 2.9*104 t/a 5.9.3 Reduction of raw materials consumption The construction scheme of Jiguanshi ship waste receiving and treatment project adopts ramp dock with river-connection road scheme. As the ships are equipped with loading/unloading equipment, so it is no need for this subproject to newly purchase loading/unloading equipment. The waste compression process of the waste secondary transfer station upgrading subprojects adopts vertical compression process, which is reliable in technology, with complete construction conditions, small land occupation area and low maintenance cost. The sewage treatment process of the waste secondary transfer station upgrading projects adopts MBR treatment process, which has high space utilization rate, requires small land area and low cost in sludge treatment. The waste plastic thermal cracking oil production line of Luoqi low-value recyclable utilization base project adopts thermal-cracking & catalytic-upgrading process. This technology requires low energy consumption, performs fast reaction Page 481 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project speed, high waste plastic treatment efficiency and large oil production amount. Comprehensively, the subprojects achieve the reduction of raw materials consumption through optimization and selection on the design schemes, compression technologies and treatment processes. 5.9.4 Reduction of pollutants discharge The construction scheme of Jiguanshi ship waste receiving and treatment project adopts ramp dock with river-connection road scheme. In this construction scheme, the excavation volume of the dock basin is relatively small (6946m3), and the change of the near-shore hydrological conditions (velocity, flow, water level, etc.) is relatively small. The Grab-bucket type excavation method is adopted for the dock basin excavation of the ship waste receiving and treatment project. The boom and steel cable of rotary dredger are used to hang the grab and put it into the river bottom to grab the soil. Then the grab will be closed and raised to the mud barge to unload the mud. Compared to the Rake-suction excavation method (with the re- suspension rate of 15~22 kg/m3), the Grab-bucket type excavation method has a lower re-suspension rate (of 10~18 kg/m3) and will generate less suspended matter, so it will cause a smaller impact on the water body and the aquatic organisms. The waste secondary transfer station upgrading projects adopt vertical compression technology as the waste compression processes. This process can keep the compression leachate from leakage so to reduce the possibility of secondary pollution, and performs better in dealing with the accidental conditions such as power failure. The sewage treatment process adopts MBR process. Compared with SBR process, the MBR process performs more flexible and continuous in water effluent, with higher removal rate as more kinds of organics being removed, as well as with better water effluent quality and lower sludge yield. The waste plastic thermal cracking oil production line of Luoqi low-value recyclable utilization base project adopts thermal-cracking & catalytic-upgrading process, which will produce less waste gas than thermal-cracking process. Comprehensively, the subprojects achieve the reduction of the pollutants generating and discharge through optimization and selection on the construction methods, compression processes, production technologies and pollutant treatment processes.

Uncontrolled releases of hazardous materials may result from small cumulative events, or from more significant equipment failure associated with events such as manual or mechanical transfer between storage systems or process equipment. Recommended practices to prevent hazardous material releases from processes include: 1)use of dedicated fittings, pipes, and hoses specific to materials in tanks (e.g., all acids use one type of connection, all caustics use another), and maintaining procedures to prevent addition of hazardous materials to incorrect tanks; 2)use of transfer equipment that is compatible and suitable for the characteristics of the materials transferred and designed to ensure safe transfer; 3)regular inspection, maintenance and repair of fittings, pipes and hoses; 4)provision of secondary containment, drip trays or other overflow and drip containment measures, for hazardous materials containers at connection points or other possible overflow points. Overfills of vessels and tanks should be prevented as they are among the most common causes of spills resulting in soil and water contamination, and among the easiest to prevent. Recommended overfill protection measures include: 1)prepare written procedures for transfer operations that includes a checklist of measures Page 485 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project to follow during filling operations and the use of filling operators trained in these procedures;2)installation of gauges on tanks to measure volume inside; 3)use of dripless hose connections for vehicle tank and fixed connections with storage tanks; 4)provision of automatic fill shutoff valves on storage tanks to prevent overfilling; 5)use of a catch basin around the fill pipe to collect spills; 6)use of piping connections with automatic overfill protection (float valve); 7)pumping less volume than available capacity into the tank or vessel by ordering less material than its available capacity; 8)provision of overfill or over pressure vents that allow controlled release to a capture point. A critical aspect for controlling accidental releases of liquid hazardous materials during storage and transfer is the provision of secondary containment. It is not necessary for secondary containment methods to meet long term material compatibility as with primary storage and piping, but their design and construction should hold released materials effectively until they can be detected and safely recovered. Appropriate secondary containment structures consist of berms, dikes, or walls capable of containing the larger of 110 percent of the largest tank or 25% percent of the combined tank volumes in areas with above-ground tanks with a total storage volume equal or greater than 1,000 liters and will be made of impervious, chemically resistant material. Secondary containment design should also consider means to prevent contact between incompatible materials in the event of a release. Spills and emergencies: 1) If employees are required to clean-up spills, they must be properly trained and equipped. 2) Evacuate personnel and secure and control entrance to the area. 3) Eliminate all ignition sources. 5)Absorb liquids in dry sand, earth, or a similar material and place into sealed containers for disposal. 6) Ventilate and wash area after clean-up is complete. 7) It may be necessary to contain and dispose of Ethylene Glycol as a hazardous waste.

In conclusion, the recommended scheme, namely the site on the south side, is better than the reserved scheme as the site on the north side in the terms of social impact, environmental protection, and construction conditions, so the recommended scheme is the preferred choice. 6.2.2 Waste Secondary Transfer Stations The three subprojects, namely Xiajiaba Waste Secondary Transfer Station upgrading project, Zouma Waste Secondary Transfer Station upgrading project, and Jieshi Waste Secondary Transfer Station upgrading project, have original sites, with less negative impacts that may be brought by land acquisition, relocation, construction and soil erosion. In addition, as these three subprojects can be reconstructed and expanded on the basis of the original transfer station facilities, it is the only feasible scheme for the reconstruction and expansion subprojects. 6.2.3 Luoqi low-value recyclable utilization base project Page 504 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The proposed construction site of Luoqi low-value recyclable utilization base is located at Taihonggang Village, Luoqi Town of Yubei District, The adjacent land is relatively flat with a favourable terrain, and the construction earthwork is small. The site is located in the downwind direction of Luoqi Town, with few surrounding residential areas and less environmental impact on the surrounding residents. Additionally, it is close to Shanghai-Chongqing expressway and enjoys convenient traffic condition. So, the site selection scheme for this project is proper. The land acquisition work of Luoqi low-value recyclable utilization base project has been completed. If other site is selected, the land acquisition is required to be done again, that will be resulted in social impact caused by land acquisition and relocation. Even worse, the demolition and construction will lead to an increase of environmental impact and risk, as well as of the land acquisition costs. Therefore, the relocation of Luoqi low-value recyclable utilization base requires certain technical research support. The construction within the scope of acquired land is a preferable scheme in terms of society, environment, economy and technology, so it is the only feasible site selection scheme. 6.3 Alternative selection of technology and process 6.3.1 Jiguanshi ship waste receiving and treatment project â‘  Alternative selection of construction schemes According to the site topography and adjacent buildings, the Designer puts forward two construction schemes for the ship waste receiving and treatment project taking into account the ship pollutant landing process requirements. The first scheme is to build sloped dock and river-connecting road, and the second is to build vertical overhead platform. The alternative analysis of the two schemes is shown in the table below.

In conclusion, from a comprehensive analysis of society, environment, investment and technology, the scheme of sloped dock and river-connecting road construction causes less water and soil loss and has better technical feasibility. It is better than the vertical overhead platform scheme in terms of environmental and social impact as well as of risk, so Scheme 1 is the preferred choice. â‘¡Alternative analysis of dock basin excavation The subproject involves dock basin excavation. In order to reduce the impact of suspended solids on water environment quality and aquatic ecological environment, an alternative analysis is carried out for commonly used dredgers and corresponding excavation methods, as shown in the table below.

In conclusion, from the perspective of society, economy, environment and technology, grab dredger suggests better social, economic and environmental benefits, so Scheme 1 is the preferred one. 6.3.2 Alternative analysis of waste compression technology The mainstream waste compression technologies applied in Waste Transfer Stations include vertical compression technology and horizontal compression technology. In order to improve the environmental and social benefits brought by the upgrading projects of the Waste Secondary Transfer Stations, two kinds of waste compression technologies are compared, namely vertical compression technology as Scheme 1, and horizontal compression technology as Scheme 2. The detailed comparison of the two schemes is shown in the table below. Page 513 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Table 6.3-3 Alternative analysis on Waste Compression Technology Schemes Comparison Which is Scheme I Scheme II item better With high space utilization rate and small occupied area, and without new land With low space occupation, it is suitable utilization rate and large for waste classification occupied area, it is not and transportation to suitable for classified meet the needs of social Scheme I is Social impact transportation and development; it can also preferred restaurant waste; it is be operated in case of unable to deal with the power failure and other emergencies such as emergencies; it is power failure unlikely to cause secondary pollution and has little impact on the community With the risk of the fugitively leaking Without leakage of leachate from its tank leachate, it is unlikely to body, so it has relatively cause secondary high risk of secondary Environmental Scheme I is pollution; the water pollution to the station impact preferred consumption for cleaning and surrounding is relatively small, so it is environment; and the good for water saving. clean water consumption is relatively large The construction cost is The construction cost is about RMB 880 million, about RMB 880 million, Scheme I is Economy and the maintenance cost and the maintenance preferred is relatively low cost is relatively high The construction The construction Both technology is mature technology is mature schemes are Technology with favorable with favorable technically construction conditions; construction conditions; feasible Both Schemes 1 and 2 are feasible in economy and technology, and Comprehensive Scheme 1 is better than Scheme 2 in environment and society, so evaluation Scheme 1 is better Page 514 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project As the table above shows, in terms of technology, the technology applied in both schemes is feasible; in terms of economy, the maintenance cost of vertical compression technology is lower and the overall economy is better; in terms of environmental and social impact, the vertical compression technology presents higher space utilization, is more suitable for waste classification and transportation, has stronger ability to respond to emergencies, is less likely to cause secondary pollution, and consumes less clean water compared with the horizontal compression technology. Therefore, the vertical compression technology is better on the whole. In conclusion, the vertical compression technology is significantly better than the horizontal compression technology in terms of social and environmental impact, so Scheme 1 is the optimal solution for the function upgrading and expansion of the Waste Secondary Transfer Stations. 6.3.3 Alternative analysis on wastewater treatment facilities Domestic sewage, production waste water and other waste water will be produced by the subprojects of the Project, so it is necessary to use the integrated wastewater treatment facilities such as assembled wastewater treatment unit. There are 2 different wastewater treatment processes for comparison, namely MBR treatment process in Scheme 1, and SBR treatment process in Scheme 2. The detailed comparison of the two schemes is shown in the table below. Table 6.3-4 Comparison and Selection of Technical Schemes for Wastewater Treatment Facilities Comparison Which is Scheme I Scheme II item better Low space utilization High space utilization rate, large occupied rate, small occupied area, Scheme I is Social impact area, and high and low requirement of preferred requirement of ground ground condition; condition; With flexible and With periodic water continuous water output; output instead of Environmental with high removal rate, continuous output Scheme I is impact many kinds of organic pattern; with low preferred matter can be removed, removal rate, only single the output water quality kind of organic matter Page 515 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project is better, and the can be removed; and the production of settled production of settled sludge is low sludge is high The equipment cost is The equipment cost is about RMB 50,000, and about RMB 30,000, and Scheme II is Economy the sludge treatment the sludge treatment preferred cost is low cost is high The construction The construction Both technology is mature and technology is mature schemes are Technology the construction and the construction technically conditions are favorable conditions are favorable feasible Both Schemes 1 and 2 are technically feasible, and Scheme 2 is Comprehensive better than Scheme 1 in economy, while Scheme 1 is significantly evaluation better than Scheme 2 in environmental and social aspects, so Scheme 1 is better According to the table above, in terms of technology, the technology applied in both schemes is feasible; in terms of economy, the equipment cost of Scheme 2 is lower and the overall economy is better; in terms of environmental and social impact, Scheme 1 presents a higher space utilization rate compared with Scheme 2, with more flexible water output, stronger removal capacity, and low settled sludge production, so Scheme 1 is better on the whole. In conclusion, the MBR treatment process is superior to the SBR treatment process in terms of social and environmental impacts. Scheme 1 is the preferred option for the wastewater treatment facilities process of the subprojects. 6.3.4 Alternative analysis on waste plastic cracking oil production technology The construction content of Luoqi low-value recyclable utilization base subproject contains the special production line of plastic cracking oil production. This assessment conducts the alternative analysis on the 2 different waste plastic cracking oil production technologies, in which the scheme 1 is Cracking & Catalytic Upgrading Process, and the scheme 2 is Thermal Cracking Process. The comparison of the 2 schemes is listed in the table below. Table 6.3-5 Table 6.3-5 Comparison of waste plastic cracking oil production technologies Page 516 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Scheme 1 Comparison Scheme 2 Which one item (Cracking & Catalytic is better?

It will cost about 48 It will cost about 20 million Yuan in million Yuan in equipment, get the oil equipment, get the oil Economy product with high Scheme 1 product with low quality quality and 28 million and 4 million Yuan as Yuan as the annual the annual income. income. The construction The construction technology is mature technology is mature Both Technic and the construction and the construction feasible conditions are conditions are complete. complete. The 2 schemes are both feasible in technical aspect, although the Comprehensive scheme 2 requires smaller land occupation, the scheme 1 is judgement better in environmental and economic aspects, therefore the scheme 1 is prefered. According to the table above, the 2 schemes are both technically feasible. In social aspect, the scheme 2 requires smaller land occupation and causes the smaller land acquisition impact; while in environmental aspect, the scheme 1 requires lower energy consumption, produces less pollutant discharge amount, and performs higher waste plastic treatment efficiency; and in economic aspect, the equipment cost of the scheme 1 is higher than that of the scheme 2, yet will get a obviously higher annual profit, therefore its long term economic benefit is better than the scheme 2. Page 517 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project In general, Cracking & Catalytic Upgrading process is obviously better than Thermal Cracking process in economic and environmental aspects, so the scheme 1 is the prefered scheme. 6.4 Alternative selection of transportation routes The solid waste of the Jiguanshi ship waste receiving and treatment project is transported by road to Fengsheng Waste Incineration Plant in Banan District for incineration. Relying on the existing Tanguang Road in the region, the transportation vehicles enter Yuhang Avenue, then enter Shizhu-Chongqing Expressway via Kaiying Road, and finally arrive at Fengsheng Waste Incineration Plant. The whole transportation process depends on the original roads, and no additional transportation roads need to be built. The transportation route is mainly composed of fast passages and expressways, which have little social and environmental impact to the communities along the route. With strong economic and technical feasibility, it can be considered as the only choice, thus it is the preferred scheme. The waste sorted by Xiajiaba Waste Secondary Transfer Station is transported to Luoqi Restaurant Waste Treatment Plant, Luoqi low-value recyclable utilization base and Luoqi Waste Incineration Plant by highway. Xiajiaba Transfer Station is close to Chongqing Ring Expressway, so that the vehicles can directly enter Chongqing Ring Expressway and then enter Shanghai-Chongqing Expressway to reach Luoqi National Resource Utilization Base. The whole transportation route is composed of expressways, which have little social and environmental impact to the communities along the route. With strong economic and technical feasibility, it can be considered as the only choice, thus it is the preferred scheme. The waste sorted by Zouma Waste Secondary Transfer Station is transported to Luoqi Restaurant Waste Treatment Plant, Luoqi low-value recyclable utilization base and Jiangjin Baiguoyuan Waste Incineration Plant by highway. As Zouma Transfer Station is close to the intersection of Chongqing-Kunming Expressway and Chongqing Ring Expressway, the transport vehicles for other waste from the transfer station can directly enter Chongqing Ring Expressway, and then enter the Third Ring Expressway to reach Jiangjin Baiguoyuan Waste Incineration Plant; the transport vehicles for kitchen waste, restaurant waste and recyclable waste from the transfer station can directly enter the ring expressway, and then enter Shanghai-Chongqing Expressway to reach Luoqi National Resource Utilization Page 518 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Base. Relying on the exist expressways throughout theroute, it will generate little social and environmental impact on the communities along the route. So this route is economically and technically feasible, and it is the only preferred option. The waste sorted by Jieshi Waste Secondary Transfer Station is transported to Luoqi Restaurant Waste Treatment Plant, Luoqi low-value recyclable utilization base and Fengsheng Waste Incineration Plant by highway. As Jieshi Transfer Station is close to the intersection of Lanzhou-Haikou Expressway and Baotou- Maoming Expressway, the transport vehicles for other waste from the transfer station can directly enter Baotou-Maoming Expressway, and then enter the Third Ring Expressway via Chongqing Ring Expressway to reach Fengsheng Waste Incineration Plant; the transport vehicles for kitchen waste, restaurant waste and recyclable waste from the transfer station can directly enter Baotou-Maoming Expressway, and then enter Shanghai-Chongqing Expressway via Chongqing Ring Expressway to reach Luoqi National Resource Utilization Base. Relying on the exist expressways throughout the route, it will have little social and environmental impact on the communities along the route. So this route is economically and technically feasible, and it is the only preferred option. Transport vehicles can reach Luoqi low-value recyclable utilization base via the two toll stations at Baijiayan and Jiantuowan in Shanghai-Chongqing Expressway. Baijiayan Toll Station is in the route of Scheme I, and Jiantuowan Toll Station is in the route of Scheme II. The two schemes are shown in the following figure.

Therefore, Scheme 1 is better as a whole. In conclusion, Scheme 1 is superior to Scheme 2 in terms of social and environmental impact. So, Scheme 1 is the preferred route for transport vehicles heading for Luoqi.

In case of any accident, it is necessary to immediately take the required actions which can control and reduce the accident impact, such as emergency shutdown and pressure relief. Meanwhile immediately contact the relevant rescue, first-aid, firefighting and public security agencies for Page 649 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project assistance to make sure that they can arrive the accident site for rescue and treatment in the shortest time, so as to minimize the accident impact. 5. Emergency Monitoring Regular inspections of facilities and of the body of the existing dump site (before and after its closure) should be performed to ensure timely observation of and response to fires, spills or leakages. In case of chemical and oil leakage accident, it is necessary to consider the impact of such leakage on the atmosphere, soil, surface water and human health at the first place. Therefore, the main content of emergency monitoring involves atmosphere, soil and surface water environment in the surrounding area. When the sewage leakage accident occurs, it mainly influences the soil and surface water, so the main content of emergency monitoring involves the quality of surrounding soil and surface water. 6. Emergency Treatment Measures (1) Treatment of chemical and oils leakage ① The area and reason of sudden accident shall be properly analyzed and judged, and proper method shall be adopted to cut off the diffusion source. Meanwhile, workers shall be organized to guard the hazardous area due to chemical and oil leakage, and control all potential ignition sources with combustible materials strictly, so to avoid possible fire explosion and escalation. ② It is required to briefly report the accident to the superior leader and the production command system, and inform the local public security and fire control departments to strengthen the precautionary measures. ③ The repair team shall be swiftly organized and sent to the site. Under the unified organization and command of the site leading team, sophisticated organization and assignment of responsibility shall be conducted in accordance with the repair plan and safety technical measures to ensure safe repair. (2) Treatment of fire and explosion ① Explosion hazard zones and relevant mitigation measures should be identified. After the occurrence of fire, the first person who discovers the fire shall immediately call 119 and briefly describe the accident time, place and fire status. ② The first person who discovers the fire shall immediately report to the duty room after calling 119. The cadres on duty shall immediately start the emergency Page 650 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project response procedure and comprehensively treat the various complex situations on site after receiving the report. ③ After the occurrence of the accident, the operation personnel at each post shall follow the unified command of the person in charge. ④ The cadre on duty shall assign the rescue tasks, investigate the casualties on site and organize and implement initial rescue work. ⑤ The cadre on duty shall report the fire status and casualties to the dispatching room of the company, and meanwhile clear the road and prepare to receive the vehicles. The personnel on duty of the fire-pump room shall alarm and inform over the loudspeaker, evacuate the personnel and vehicles, and prepare for starting the fire pump. ⑥ If the fire is caused by leakage, the dispatching room shall requests to stop and cut off the transmission. ⑦ After the full-time fire team arrives the site, the cadre on duty shall introduce the fire status and extinguishing work, and assist in formulating the fire extinguishing plan. Other personnel shall leave the fire extinguishing site and follow the unified command of the cadre on duty to carry out shifting process and fire extinguishing assistance work properly. ⑧ If the fire pump and fire foam pump are started in the fire extinguishing process, the personnel on duty of the fire pump room shall timely supplement the liquid in the fire protection water tank and foam tank to ensure adequate liquid volume of the water tank and foam tank. ⑨ When the fire cannot be controlled, the staff shall quickly evacuate to the area outside of the flame’s injurious heat radiation. ⑩ After confirming that the fire and explosion site is thoroughly under control, the leader of Response Team shall check the number of people and organize to clear the site for relieving the emergency status. (3) Emergency treatment measures for sewage leakage ① On the basis of correct analysis and judgement on the area and reason of the sudden accident, the mergency response team shall organize manpower to cut off the diffusion source with appropriate methods, and guard the dangerous area of sewage diffusion. ② Immediately report the accident to the superior leader in charge and the Page 651 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project production command system, and inform the local environmental protection and fire department to strengthen the preventive measures. ③ An emergency repair team is required to be organized and sent to the site immediately. Under the unified organization and command of the on-site leading group, the emergency repair team will carry out emergency repair for the accident equipment according to the established emergency repair plan and safety technical measures. ④ After the accident is under control, the emergency repair team shall detect and monitor the damage caused by the accident, and determine the damage area, nature and degree of the accident. In view of the actual harm and possible harm to soil and surface water environment, the emergency response team should take measures such as sealing, isolation, decontamination and detection in time to prevent the environmental pollution from expanding, clean up the site and restore the infrastructure in time, so to restore the accident site to a relatively stable basic state. Page 652 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Annex 3 Primary Transfer Station Chongqing primary waste transfer stations are widely and evenly distributed in the main urban areas, with a total transfer scale of 9722.2 t/d. Upon completion of the upgrading projects of the three secondary transfer stations involved in the Project, the total transfer capacity will be 16250 t/d. Hence, the Project can rely on the primary waste transfer station for collection and preliminary sorting of most of the domestic waste in the main urban areas of Chongqing.

Introduction This Traffic Management Plant (TMP) sets out a set of generic requirements for the traffic management during the construction of the World Bank projects in Chongqing. It is designed as general guidelines which can be adapted to the project-specific traffic management plan as part of the Environmental and Social Management Plan (ESMP) or other relevant safeguards documents of the specific project. The objective of this TMP is to establish the general requirements on traffic management which will be implemented by the project contractors, so to avoid and minimize the traffic disturbance and ensure the safety of public and the project workers during the project construction. This TMP is intended to be used for traffic management during the construction stage of a project which may have potential impacts on road traffic and related public/worker safety caused by road traffic. These issues include e.g. direct road construction, maintenance and occupation of roads or sidewalks by the construction activities, the construction vehicles/equipment entering public roads, as well as the construction vehicles/equipment running through the local community roads, etc. During the preparation of a specific World Bank project in Chongqing, a project- specific traffic management plan, which adopts this TMP as a general framework and takes the project-specific situation and demand into consideration, will be developed as a part of the project’s ESMP or other safeguards documents as appropriate. During the implementation of the project, this TMP (or the project- specific TMP) will be incorporated into the bidding documents and latterly into the construction contracts, as a part of the environmental and social management specifications. The key mitigation measures of the TMP as arranged in the following structure: 2.0 Contractor’s Traffic Management Plan 2.1 Road Closure/Partial Occupation of Public Roads 2.2 Pedestrian/Cyclist Safety 2.3 Safety of Construction Workers 2.4 Construction Vehicle/Equipment Management Page 667 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project 2.5 Community Relations 2.6 Accident Reporting and Response Plan 2.7 Road Transportation Safty plan 2. Traffic Management Measures 2.0 Contractor’s Traffic Management Plan 2.0.1 The Contractor is required to develop a detailed Contractor’s Traffic Management Plan (C-TMP) prior to the commencement of the construction.

Introduction This Camp Management Plan (CMP) sets out a set of generic requirements and standards for the construction camp management for the World Bank loaned projects in Chongqing. It is developed as general guidelines which can be adapted to the project-specific camp management plan as part of the Environmental and Social Management Plan (ESMP) or other relevant safeguards documents of the specific project. The objectives of the CMP are to: • Establish standards on worker welfare and living conditions at the camps that provide a healthy, safe and comfortable environment. • Develop a set of generic measures to be implemented by the Contractor to avoid or reduce potential adverse impacts of construction camps on the environment and the surrounding communities, and to maintain good relationships between construction camp and surrounding communities. This CMP is intended to be used for all the World Bank loaned projects in China, in which construction camp is foreseen to be needed and provided by the Contractor65. Given the different scales of projects and specific local contexts, the types and scales of different construction camps may vary substantially, thus the potential environmental and social impacts related to construction camps should be considered accordingly. The set of generic requirements and measures covers a full range of aspects of large construction camps, typically related to large scale infrastructure projects. For the moderate or small-scale projects where the number of workers is relatively small, not all the requirements and standards in this document are applicable. Therefore, the requirements list below may be proportionally or selectively used for the development of the project-specific camp management plan for such projects. This CMP does not apply to the situation in which accommodation is self-arranged by the 65 workers themselves and is not the responsibility of the Contractor, e.g. local workers from nearby communities. Page 674 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The following table illustrates the potential environmental and social impacts related to construction camps, and advices on project-specific camp management plan development. Types of Application of Positive Impacts Negative Impacts Accommodation this CMP - Land acquisition and resettlement or temporary occupation; - Minimize - Camp construction interaction with related impacts such as Project-specific surrounding dust, noise, waste, etc.; CMP in the communities; - Environmental, project’s health and safety issues safeguards - Reduce related to camp operation, documents pressure on e.g. wastewater, solid (and the later community waste, noise, food safety, C-CMP) should New infrastructure and worker’s health, etc.; address all construction of services; aspects under workers’ camp - More - Potential impacts the Chapter 2 effective on nearby communities and 3 of this management of from camps with large CMP, with workers’ health number of workers, e.g. proportional and safety issues, religious or cultural consideration and enforcement conflicts, increased spread to the specific of code of of communicable diseases project context. conducts; such as HIV/AIDS and other sexually transmitted diseases, gender-based violence and harassment (GBVH) risks. - Increase demand of Project-specific - Avoid new infrastructure, services CMP in the construction of and utilities etc.; project’s camps; safeguards - Development of - Increase documents illicit trade activities; income of (and the later surrounding - Disturbance of C-CMP) should Rental of communities; community life; mainly focus existing housing - Potential religious on - Promote or cultural conflicts; management of local business worker’s (shops, - Inflation in local behavior and restaurants etc.). costs; interaction - increased spread of with communicable diseases communities Page 675 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project such as HIV/AIDS and (section 3.2, other sexually transmitted 3.4, 3.5 and diseases; 3.6), while - GBVH related risks. ensuring the rental houses have decent living and sanitation standards (comparable to relevant provisions in 2.4) During the preparation of a specific World Bank loaned project in China, this CMP will be used as a template for the development of a project-specific camp management plan, taking into account project-specific situation and demand, as part of the project’s ESMP or other safeguards documents. During the implementation of the project, the project-specific camp management plan shall be incorporated into the bidding documents as part of the environmental and social management specifications.

Dredging methodology Dredging methods are finalized based on some key factors such as environmental baseline of the project area, chemical and physical composition and behavior of the sediments, dredged materials disposal options and sites, etc. 1.1 Environmental baselines of the Jiguanshi Pier Jiguanshi ship waste receiving and treatment project located in the right bank of the Yangtze River in Jiguanshi, Nan’an District, Chongqing. Baseline data of Nan’an District can be seen as follow, (1) Atmospheric environment According to the data of Ecological Environment Bulletin of Chongqing in 2019 published by Chongqing Ecological Environment Bureau on June 3, 2020, the data of Nan’an District are not up to the secondary standard limit value of Ambient Air Quality Standard (GB3095-2012). Thus, Nan’an District is not up-to-standard areas. This is mainly due to the fact that Nan’an District belongs to the main urban area, and the traffic pollution is relatively large, as well as due to the dust emission from the construction site of urban infrastructure construction and the industrial pollution emission of the industrial park in the urban area. In this regard, Chongqing has formulated the Implementation Plan of Chongqing Carrying out the State Council's Three-year Action Plan to Win the Blue-Sky Protection Campaign, for continuously improving the environment air quality. (2) Surface water environment Considering the potential impact of Jiguanshi ship waste receiving and treatment project on the Yangtze River, this assessment has quoted surface water monitoring data of three sections, including upstream section (in the upstream of Jiguanshi ship waste receiving and treatment 694 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project project), downstream section (in the downstream of Jiguanshi ship waste receiving and treatment project) and Jiguanshi Wastewater Treatment Plant section. The surface water monitoring results of the upstream section and downstream section reach the limit of Category III values in Environmental quality standards for surface water (GB3838- 2002). The surface water monitoring results of the Jiguanshi Wastewater Treatment Plant section reach the limit of Grade 1A in Discharge standard of pollutants for urban sewage treatment plant (GB 18918-2002). Thus, the environmental quality of surface water in this area is good. (3) Acoustic environment According to the monitoring results of proposed site of Jiguanshi ship waste receiving and treatment project (N1) and old site of Jiguanshi School (N2) reach the limit of Grade II functional area of Environmental Quality Standard for Noise (GB 3096-2008). Thus, the environmental quality of noise in this area is good. 1.2 Chemical and physical composition and behavior of the sediments (1) Sediment environment quality Four monitoring points are arranged in the proposed site and upstream/downstream of the Jiguanshi ship waste receiving and treatment project (including dock basin excavation) to monitor the current status of the sediment. The monitoring results of arsenic, mercury, copper, cadmium, nickel and lead at sites D1-D4 all meet the other screening standards of pH>7 in GB15618-2018. Therefore, the environmental quality of the sediments of the subproject is good, and it is not toxic or harmful. (2) Physical behavior of the sediments Jiguanshi ship waste receiving and treatment project will include one time small scale dredging (total 6946 m3) of low water content sand (35%), which is expected to last 5 days. Based on the the feasibility study report, the river bed in the river section where the project is located is basically stable, with dynamic balance of flood season siltation and dry season scouring, and without accumulation of siltation. Therefore, in the operation of the project, it will be no need to do maintenance dredging. 1.3 Dredged materials disposal options and sites 695 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project The earthwork produced during dock basin excavation is planned to be dried in the mud- dumping yards (It is planned to set 2 or 3 mud-dumping yards at the river bank, and a grit chamber will be set in the lower part near the mud-dumping yards. After waste slags are settled still, the water will return to the main river stream. The hydraulic retention time is about 50h. In the construction process, the alternate use method of the mud-dumping yards is adopted to avoid the increased flow rate caused by too high water level in the mud-dumping yards, and ensure sufficient sediment of waste slags, so to largely avoid possible adverse impacts of the water return from the mud-dumping yards on the quality of the river water.) Part of the earthwork is designed to be used for land backfill, and the other will be transported to Luoqi landfill. The sediment will exert minimal impact on the environment after being properly treated. The location for the settling basins should be carefully selected based on following criteria: ① The contractor should carefully design its work site layout within the redline boundary approved by the government; ② The contractor should ensure the adequate land area for retention time at 50 hours; ③ The settling basin should avoid flooding area and landslide area; ④ The settling basin should near the site with dredging operation; ⑤ The settling basin should be backfilled immediately after it is closed. 2. Assessment scope According to the dredging methods, the influence area has been defined as follow: Table 1 Assessment Level and Scope of Jiguanshi ship waste receiving and treatment project Environmental Assessment level Jiguanshi ship waste receiving and treatment project factor and scope Ambient air68 Assessment level Grade III 68 According to ‘Technical guidelines for Environmental Impact Assessment : Atmospheric Environment’ (HJ 2.2-2018), the method of grade division is: according to the calculated maximum surface air mass concentration 696 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Environmental Assessment level Jiguanshi ship waste receiving and treatment project factor and scope Assessment scope / Assessment level Grade IIIB Surface Water69 From the upstream 500m to the downstream 500m of the Assessment scope planned site for the dock. Acoustic Assessment level Grade II environment Assessment scope 200m outside the boundary Assessment level Grade III Ecological Terrestrial Ecology: 500m outside the boundary environment Assessment scope Aquatic ecology: From the upstream 500m to the downstream 500m of the planned site for the dock Soil Assessment level Grade III environment70 Assessment scope 50m outside the boundary 3. Mitigation measures Besides, during the construction period of Jiguanshi ship waste receiving and treatment project, the excavation of the dock basin and the sludge excavated on the shore will have a certain impact on the environment. Therefore, it is necessary for this project during the construction period to take some special environmental impact mitigation measures. Please see Table below. (occupation to the standard value) rate Pi (the ith pollutant, referred to as the "maximum concentration ratio") of the main pollutants of the project, while the maximum concentration ratio Pmax < 1%, the Grade is III; while 1% <= Pmax < 10%, the Grade is II; while Pmax>=10%, the Grade is I. As the results of caoculation, among the 5 subprojects, besidesJiguanshi ship waste receiving and treatment project ’s Pmax < 1% (Grade III), the rest 4 subprojects’ Pmax values are all between 1% and 10% (Grade II). According to ‘Technical guidelines for Environmental Impact Assessment : Surface water Environment’ (HJ 69 2.3-2018), the assessment grade of construction project with water pollution is classified with its wastewater discharge mode and amount. The construction project with direct discharge of wastewater is divided as Grade I, Grade II and Grade IIIA according to the wastewater discharge amount and the pollution equivalent of water pollutant; the project with indirect discharge of wastewater is classified as Grade IIIB. Therefore, all the 5 subprojects are Grade IIIB. According to ‘Technical guidelines for environmental impact assessment Soil Environment (Trial)’ (HJ 964- 70 2018), the soil environmental impact assessment is classified as Grade I, Grade II and Grade III. Based on the Annex A of the Guideline, among the 5 subprojects, only Luoqi low-value recyclable utilization base project is classified as Grade III which requires soil environmental impact assessment work. As the land occupation of the base is medium-sized, and the soil environmental sensitivity is sensitive (there is arable land around the project), according to the soil environmental impact assessment project category, land occupied scale and sensitivity, the assessment work is divided into Grade III. 697 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Table 2 Special mitigation measures for Jiguanshi ship waste receiving and treatment project Impact Mitigation measures factor 1) The excavation area of the harbor basin is mainlywater related construction. During the construction period, the dredger is used for construction. It is necessary to do manage the collection and transportation of earthwork well, and timely transport it to the designated place for backfill. It is forbidden to temporarily stack or even discard the abandoned earthwork on the river bank. The construction team should connect earthwork excavation with transportation well, and try to achieve that earthwork can be transported away immediately after excavation. Basin 2) Before the construction: one temporary drainage ditch is set at the upstream excavation side of overhead ramp, and a temporary grit chamber is set at the outlet of the drainage ditch. The construction diversion shall be prepared well before the construction of wading pile foundation. 3) During the construction: Woven bag temporary retaining wall is set around the land pile foundation for blocking, and non-woven fabric is used to cover the disturbed bare surface and temporary storage of sandy materials. 4) Later stage of construction: The vegetation restoration area and temporary construction area in the site shall be prepared and sown for greening 5) Two or three mud dumps are set on the river bank, and a grit chamber is set at the lower part near the mud dumps. After the waste slag staticly settles, the water in the mud dumps will return to the main stream, and the hydraulic retention time is about 50 hours. In order to avoid the increasing flow velocity caused by too high water head in the mud dumps, and ensure that the waste Sludge slag can be fully precipitated, the mud dumps are alternately switched to use in the construction process. This greatly avoids the adverse impacts on the water quality of the river caused by the backwater from the mud dumps. The earthwork generated from the excavation of the harbor basin is dried in the mud dumps, part of which is used for land backfilling, and the rest of which is transported to Luoqi landfillsite. 698 Environmental Impact Assessment Report for the First Batch of Chongqing Sub-project Annex 7 Test Report on Baiguoyuan Waste Incineration Plant (attached) 8.
