1. Project overview 1.1 Project background In September 2013, the Foreign Economic Cooperation Office of the Ministry of Environmental Protection and the World Bank cooperated to launch the “China Contaminated Site Management Project”. The aim of this project is to conduct environmental survey and initial risk assessment of potential persistent organic pollutant (POP) contaminated sites in China; selection of typical POP contaminated sites to carry out exploration of financing mechanisms for treatment of contaminated sites that is suitable for China; development of site risk management measures or management engineering demonstrations, drive and improve policies, regulations, and standard systems on prevention and treatment of contaminated sites in China; and improve China’s environmentally sound management capabilities. After approval by the People’s Government of Liaoning Province, the Department of Environmental Protection of Liaoning Province submitted an application for participation in provincial demonstration activities to the Foreign Economic Cooperation Office of the Ministry of Environmental Protection. This was endorsed by the World Bank and Foreign Economic Cooperation Office of the Ministry of Environmental Protection of Liaoning Province was selected as a model province for this project. The manufacturing zone of the north factory in Beier Road of Northeast Pharmaceuticals Group Co Ltd which has a history of DDT manufacturing was included in POP contaminated site management engineering. The Northeast Pharmaceutical Group Co. Ltd was formerly the Northeast General Pharmaceutical Factory. The former Beier Road North Factory was located in 37 Chonggong North Street in Tiexi District in Shenyang City, has an area of 120,000 m2, and is mainly involved in pharmaceutical manufacturing. This factory started production in 1949 and stopped production in April 2015 to be shifted to the Shenyang Economic Technological Development Zone. In 2016, in accordance to municipal construction requirements by the Tiexi People’s Government, municipal roads with widths of 11m and 6m were constructed at the northern and western sides of the factory. Currently, the factory area is 114,000 m2. According to the overall land use regulations by the government, this site will be redeveloped and used for residential land (category 2 residential land). On 12 February 2017, China Resources Land Limited (Shenyang) successfully obtained this site through auctions. According to national and local

Ltd 1#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site relevant management requirements for contaminated sites, before land previously used for industrial purposes are redeveloped in commercial or residential land, environmental surveys and risk assessment on that land should be carried out to ensure the environmental safety when the land is reused, and confirm the treatment and remediation measures that are required for contaminated land. According to the “Northeast Pharmaceutical POP site (The manufacturing zone of the north factory in Beier Road of Northeast Pharmaceuticals Group Co. Ltd) detailed environmental survey and risk assessment report” and “Northeast Pharmaceuticals SOP site (The manufacturing zone of the north factory in Beier Road of Northeast Pharmaceuticals Group Co. Ltd))”, soil restoration of the Northeast Pharmaceuticals Factory POP contaminated site was carried out using in situ remediation and ex situ remediation. The remediation process will be completed in two factories; of which in situ remediation will be carried out at the original Northeast Pharmaceutical Factory North Factory Site (i.e. contaminated site) and ex situ remediation will be carried out at the New Factory Site of the Northeast Pharmaceuticals Factory. In January 2018, Shenyang Luheng Environment Consulting Co. Ltd successfully obtained the procurement bid for Global Environment Facility “China China Contaminated Site Management Project” (Liaoning demonstration project-Evaluation of environmental and social effects of the Northeast Pharmaceutical Factory POP pollution site) of the “China Contaminated Site Management Project” Project Management Office of the Department of Environmental Protection of Liaoning Province. The company is responsible for evaluation of environmental effects of the Northeast Pharmaceutical Factory POP contaminated site. After our company has been commissioned, we conducted a careful study of materials related to this project, and carried out field reconnaissance and on-site investigations, collection and verification of relevant materials. We carried out evaluation of environmental effects in this project according to relevant technical regulations and drafted and completed this report. 1.2 Aim of assessment According to the “Northeast Pharmaceutical POP site (Manufacturing zone of the north factory in Beier Road of Northeast Pharmaceuticals Group Co. Ltd) detailed environmental survey and risk assessment report” and “Northeast Pharmaceuticals SOP site (The manufacturing zone of the north factory in Beier Road of Northeast Pharmaceuticals Group Co. Ltd))”, soil

The remediation process will have some effects on surrounding environment. This evaluation is mainly carried out by investigation, monitoring, and comparative analysis of the natural environment, social environment, and current status of environmental quality in the region in which the project is located at. This is done so as to predict the nodes, types, emission concentration, emission amount of pollutants produced during the implementation process of the project and the effects of various pollutants on the surrounding environment. This is combined with the current status of environmental quality and evaluation of the rationality of project implementation to propose specific solutions and measures to prevent and control pollution and mitigate adverse effects, so as to prevent secondary pollution as much as possible when conducting harmless treatment of the existing contaminated site, reducing adverse environmental effects to a minimum, and propose a scientific basis for approval and management of this project by the administrative department of environmental protection. 1.3 Basis for evaluation 1.3.1 Laws and regulations (1) (Comes into force in 1 January 2015); (2) (Comes into force in 1 June 2015); (3) (Comes into force in 1 September 2003); (4) (Comes into force in 1 January 2016); (5) (Comes into force in 1 June 2008); (6) (Comes into force in 1 March 1997); (7)

1.5.1 Evaluation grade (1) Determination of evaluation grade for atmospheric environment According to regulations in the (HJ2.4-2008), the major atmospheric environmental problems in this project is dust produced from soil dredging, soil remediation, and soil transport at the contaminated site, dust from construction and transportation vehicles, and VOCs, SVOCs, dust, HCl, and 1-4 dioxin produced during ex situ soil remediation. The evaluation grade for atmospheric environment is grade 3. (2) Determination of evaluation grade for noise According to delineation of applicable zones for Shenyang environment noise standards, the contaminated site (original Northeast Pharmaceutical Factory North Factory) should implement (GB3096-2008) categories 2 and 4a. Category 3 standards of the “Emission standard for industrial enterprises noise at boundary” were implemented for environment noise for the boundary of the remediation site (Northeast Pharmaceutical Factory New Factory). As the maximum increase in noise is lower than 3dB (A) after this project is operational, changes in the affected population are not large. According to the (HJ2.4-2009), this evaluation confirms that the grade of noise environment impact assessment is Grade 2. (3) Determination of evaluation grade for surface water In situ remediation project and ex situ remediation project were both less than process wastewater discharge. Of these projects, the wastewater produced during in situ remediation of the contaminated site is mainly water used to wash the tires of transportation vehicles and domestic wastewater of construction workers. Wastewater from cleaning of vehicles was fully reused while domestic wastewater was treated at the Xiannuhe wastewater treatment plant after passing through the municipal wastewater network. The wastewater generated during ex situ remediation was mainly domestic wastewater from staff, caustic wash tower effluent, and quench tower effluent. These wastewater all achieved standards after treatment at the integrated wastewater treatment plant in Northeast Pharmaceutical Factory New factory before being discharged through the municipal wastewater network into Shenyang Western Wastewater

Ltd 29#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site isolated and washed, wet azide products were formed. Under the effects of ethyl acetate and drinking water, wet azide products undergo stratification. Following that, deprotection is carried out under the effects of methanol and sodium benzenesulfonate. The product then undergoes filtering, discoloration, crystal isolation to obtain the active pharmaceutical ingredient for zidovudine (AZT). 2. Berberine manufacturing process Berberine manufacturing undergoes cyclization, cyanidation, amination, methylation, condensation, cyclization, and copper removal to obtain the crude product berberine. This crude product undergoes refining to obtain the berberine end-product. Firstly, catechol and dichloromethane react under the presence of sodium hydroxide and tetrabutylammonium bromide to produce 1,3-Benzodioxole. 1,3-Benzodioxole reacts with formaldoxime hydrochloride to form piperonyl chloride. Piperonyl chloride reacts with sodium chloride under the presence of tetrabutylammonium bromide to form piperonyl cyanide. Piperonyl cyanide reacts with hydrogen under catalysis with Raney nickel to form piperonyl ethylamine. Ortho-vanillin reacts with dimethyl sulfate under the presence of sodium hydroxide and tetrabutylammonium bromide to form methyl ortho-vanillin. Piperonyl ethylamine and methyl ortho-vanillin undergoes condensation reaction to form a Schiff base, which reacts with hydrogen under catalysis with Raney nickel to form a condensate. The condensate reacts with HCl to form a hydrochloride condensate. The hydrochloride condensate, glyoxal, and anhydrous cupric chloride undergo cyclization to form copper berberine. This reacts with hydrogen peroxide in the presence of hydrochloric acid to form crude berberine. Crude berberine is refined to obtain the berberine end-product. 3. Vitamin B1 manufacturing process Methanoic acid and methanol undergoes esterification to form methyl methanoate. Following that, this reacts with acrylonitrile to undergo formylation to form a sodium salt, which undergoes further methylation, condensation, and distillation to produce acetal. Acetal then undergoes condensation with sodium methoxide and acetamidine hydrochloride before hydrolysis, freezing, and centrifugation to obtain 2-methyl-4-amino-5-acetylaminomethyl pyrimidine. 2-methyl-4-amino-5-acetylaminomethyl pyrimidine undergoes alkaline hydrolysis, before reacting with methanol, ammonium chloride, and carbon disulphide to undergo

Ltd 30#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site ammonium salt reaction. Following that, a chlorohydrin solution was added for condensation before cyclization, neutralization, and centrifugation to obtain thiothiamine. Thiothiamine then undergoes oxidation with hydrogen peroxide, before decoloration, centrifugation, before ammonium nitrate was added for salt conversion, neutralization to obtain thiamine nitrate. Thiamine nitrate undergoes conversion with methanol and hydrogen chloride gas before dissolution and refining to obtain vitamin B1. 4. Manufacturing process of L-carnitine and its series of products 1) Epichlorohydrin undergoes catalysis and reacts with water before distillation to obtain S)-(+)-Epichlorohydrin. S)-(+)-Epichlorohydrin then reacts with trimethylamine hydrochloride in ethanol solution to undergo amination. After cooling and crystallization, quaternary ammonium salt is obtained. Sodium chloride solution is then added dropwise onto the methanol solution containing the quaternary ammonium salt for cyanidation. Following that, the mixture is cooled and sodium chloride is removed. After the filtrate is concentrated, anhydrous methanol and injectable carbon was added for reflex, dissolution, and discoloration, before pressure filtration, cooling, crystallization, filtration, and drying to obtain the cyanide. The cyanide and refined hydrochloric acid then undergoes a thermal insulation reaction before concentration into a viscous mixture. After cooling, ammonia was added for pH neutralization to neutral pH, before cooling and filtration to remove ammonium chloride. The filtrate is then drawn into an addition tank and sodium metabisulfite was added for an addition reaction. Following that, the solution is diluted and undergoes ion exchange. After the eluate was concentrated to a certain volume, carbon was added for discoloration and adsorption. After discoloration, filtration was carried out to remove carbon. Then, an anionic resin was added for adsorption, before filtration. The filtrate was drawn into a secondary concentration tank and concentrated until a dry powder is obtained. Then, anhydrous ethanol was added for reflux and dissolution. The solution is then passed through a pressure filter into a crystallization tank. After concentration to a certain volume of ethanol, the solution was cooled before acetone was added for cooling and crystallization, filtration, drying, and packaging to obtain L-carnitine end products. 2) A certain amount of L-carnitine filtrate is drawn into a concentration tank and concentrated until a dry powder is obtained. Following that, glacial acetic acid was added to

After the reaction was complete, the material was concentrated to dryness and anhydrous ethanol was added for reflux and dissolution. The solution is then passed through a pressure filter into a crystallization tank for cooling and crystallization, filtration, drying, and packaging to obtain L-acetyl-carnitine end product. 3) The L-carnitine solution was passed through a pressure filter into a reaction tank and tartaric acid was added for reflux and dissolution, insulation before cooling and crystallization, filtration, drying, and packaging to obtain L-carnitine tartrate end product. 4) The L-carnitine solution was passed through a pressure filter into a reaction tank and fumaric acid was added for reflux and dissolution, insulation before cooling and crystallization, filtration, drying, and packaging to obtain L-carnitine end product. 5) A certain amount of L-carnitine filtrate is drawn into a reaction tank and hydrochloric acid was added dropwise to react. After insulation, the solution was concentrated to obtain a dry powder and isopropanol was added for reflux and dissolution. Following that, cooling and crystallization, filtration, drying, and packaging were carried out to obtain L-carnitine hydrochloride end product. 5. Sterile powder for injection process After pre-processing of fosfomycin sodium, aseptic processing and capping were carried out. Testing was conducted after packaging and stored in the warehouse after passing the test. 6. Piracetam manufacturing process Crude piracetam is heated to dissolve in isopropanol and activated charcoal was added for discoloration before pressure filtration into a crystallization tank. Normal water and salt water was added to decrease temperature until piracetam crystallizes and is precipitated out. The material was filtered using a centrifuge to obtain solids. Isopropanol was used to wash the solids. The refined wet piracetam was then dried using a double cone dryer and packaged after passing tests. 7. Aminobutyric acid manufacturing process 2-Pyrrolidinone is reacted with a digestive fluid to undergo hydrolysis under specific temperature, pressure, and reaction time, before ammonium bicarbonate and charcoal were added for discoloration and calcium removal. After passing assays, the solution is cooled,

Ltd 32#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site centrifuged, and filtered to obtain crude filtrate, which is passed through a pressure filter into a crystallization tank. After concentration, dehydration, ethanol addition and crystallization, centrifugation, filtration, and drying into a powder, aminobutyric acid is obtained. 8. VA acid manufacturing process Methanol is added into a reaction tank, mixed, and heated so that the tank temperature reaches 47-48℃. VA crystals are added and stirred to ensure that the tank temperature is maintained at 47-48℃ and VA crystals fully dissolved. Silver oxide is added into the reaction tank and the tank temperature: is maintained at 47±1℃. After the tank temperature has stabilized, potassium hydroxide solution is added dropwise. If the temperature exceeds 70℃, cold water is immediately pumped into the sandwich layer for cooling to prevent blanking. After the temperature has decreased, the remaining alkali can be added at a faster speed and the addition time is around 10-15 min. After alkali addition has completed, the tank temperature is maintained, and insulated reaction occurs for 1 hour. A filter funnel is placed (containing two layers of filter paper) and the solution is filtered into an acidification tank. The silver oxide filter cake is drained and 120L chloroform was used to wash the filter cake, before draining for further processing. The acidification tank is turned on for stirring and sulfuric acid is added dropwise until the solution pH=3-4 (around 60-75 L of acid consumed). Chloroform is added to the acidification tank for extraction, with the water layer on top and the material layer below. The material solution is combined into a wash tank and the waste acid is stored at a storage tank. Purified water is added into the material solution and mixing and stratification is initiated. The water layer is on top while the material layer is below. Repeated washing of the material solution is carried out until the wash solution reaches a pH=6.5-7 and is released into a storage tank. If there is an emulsion layer, this is also released into the tank for concentration and processing. A filter funnel is placed (containing two layers of filter paper) and the solution is filtered into a distillation tank and the residue is discarded. The material liquid is decompressed and concentrated and brownish-yellow crystalline substances are precipitated at the late stage of concentration until a viscous state is reached before concentration is stopped. Chloroform is then added for redisolution until the solution is clear and without crystals. The solution is then left overnight. A filter funnel is place (one layer of electrical filter bag). The material solution is placed into the funnel and drained till dryness before the crystals were washed with 3-4L of

Ltd 33#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site chloroform until color requirements are fulfilled before draining is continued. After the material is drained, it is placed into a drying tray and air-dried for 8-12 hours. 9. Silver sulfadiazine manufacturing process Purified water is added into reaction tank and heated before sulfadiazine is added and mixed for 5-10 minutes. Silver nitrate solution is added dropwise and reacted for 20-30 minutes. The measured pH should be 1-2. After the reaction has ended, ammonia is added dropwise to neutralize the reaction solution to pH=7. The solution is mixed for another 20-30 minutes. The reaction solution is retested to be pH 7 and placed into a centrifuge for dehydration and drying. The material is placed onto a drying tray and covered. The tray is placed in a drying cabinet and dried at 87±2℃ until constant weight and the drying duration is 15-20 h. The material is rotated every 2 hours and weighed at 14 hours before drying for another 1 hour to constant weight. The dried material is weighed, crushed, packaged, weighed, and the laboratory is notified to carry out sampling. 10. Febuprol manufacturing process Febuprol manufacturing mainly includes 7 processes of alcohol-alkane condensation, epoxidation, washing, vacuum distillation, phenol-ether condensation, washing and removal of phenol, distillation. The specific processes are described as follows: ●Alcohol-alkane condensation Epichlorohydrin and n-butanol is added into a reaction tank and mixed. The cover of the reaction tank is opened and aluminum chloride is rapidly added and mixed. Cooling water is allowed to enter the sandwich layer and sulfuric acid is gradually added dropwise into the reaction tank. ●Epoxidation The alcohol-alkane reaction solution is released into the epoxidation tank and mixing and cooling of the sandwich layer is initiated. 50% sodium hydroxide is added dropwise and mixed for the reaction to proceed for 2 hours before mixing was stopped. The solution was then left to stand for 2 hours and the reaction is completed. ●Washing Sodium hydroxide solution was first added to the epoxidation tank and mixed for 3 minutes before leaving to stand for 30 minutes. Then, sodium chloride solution was added to the

Ltd 34#109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site epoxidation tank, mixed for 3 minutes and left to stand for 30 minutes. Finally, distilled water was added to the epoxidation tank, mixed for 3 minutes, and left to stand for 30 minutes. ●Vacuum distillation The washed crude epoxypropyl ether is transferred into a distillation tank. After the vacuum has stabilized, the sandwich layer is heated and the distillate is collected in stages until no more distillate is obtained. Low-boiling residue undergoes epoxidation again while high-boiling residues are collected for environmental processing. ●Phenol-ether condensation The epoxypropyl ether is transferred into the phenol-ether condensation tank and phenol is added. Sodium hydroxide is immediately added so that the pH value becomes 11-12. ●Washing and phenol removal Sodium hydroxide solution is used for multiple rounds of washing. Washing method: Mixing for 3 minutes, leaving to stand for 30 minutes. The lower water layer is drained off while the top layer is the material layer. Sodium chloride solution was then used to wash using the same method as above for each round of addition of sodium chloride solution. ●Distillation (refining) Crude products that have passed the assay are transferred into the distillation tank. Cold water is allowed into the cooler. With continuous increase in the temperature in the oil bath, distillate is gradually released. 11. Furosemide manufacturing process Pure water is added to the sodium salt tank and mixed before sodium bicarbonate is added and heated to fully dissolve. Furosemide is slowly added to dissolve. When dissolution is slowed, sodium bicarbonate is re-added before furosemide is added. The pH is measured to be 8-8.5 and activated charcoal is added for insulated discoloration for 45 minutes. The valve at the bottom of the tank is slowly rotated so that the material solution is placed into the filter. Filtration: if charcoal leaks out during filtration, the filtrate will turn black. Return the filtrate and carry out filtration again until completion. The filtrate is combined and mixed before neutralization with acetic acid at a speed of 0.56 L per minutes. Neutralization is completed around 3 hours. Acetic acid is then added dropwise for 2.5 hours and pH is measured repeatedly until the neutralized pH is 4-5. Mixing was continued for 30 minutes before centrifugation and filtration. Pure water was

2.5.1.2 Investigation and Evaluation of Surface Water Environment Status The wastewater generated during soil excavation mainly includes the flushing water for the wheels of transport trucks, and domestic wastewater generated by construction personnel. The flushing water for the wheels of transport trucks is treated in the settling pond and used cyclically, but is not discharged to the outside. The domestic wastewater generated by construction personnel is treated in the septic tank first, and then discharged to Xiannvhe Sewage Treatment Plant through the municipal sewage pipe network. The wastewater is not directly discharged to surface waters, so the evaluation of surface water quality is not involved in this project.

2.5.1.3 Investigation and Evaluation of Noise Environment Status Dalian Jingcheng Shenghongyuan Test Technology Co., Ltd. is commissioned to monitor the noises around the original Northeast General Pharmaceutical Factory from December 27th to 28th, 2017.

2.5.1.5 Evaluation of Groundwater Environmental Quality Status The monitoring data on the groundwater within the remediation range is mainly available from Risk Evaluation Report on POP-contaminated Site of Northeast General Pharmaceutical Factory, which was prepared by Shenyang Academy of Environmental Sciences in November 2017. Shenyang Academy of Environmental Sciences has sampled the groundwater for three times. The first groundwater sampling was conducted on June 19th, 2017; six groundwater samples and one parallel sample (G2) were acquired. The second groundwater sampling was conducted on July 29th, 2017; G5 was sealed for unknown reasons, and thus the groundwater in G5 could not be sampled; then, five groundwater samples and one parallel sample (G6) were acquired. The third groundwater sampling was conducted on October 27th, 2017; G1, G4, and G5 were sealed for unknown reasons, and thus the groundwater in G1, G4, and G5 could not be sampled; then, three groups of groundwater soils (G2, G3, and G6) and one group of parallel samples (G2) were acquired. According to the test results, the values of certain conventional indexes (including permanganate index, chroma, chloride concentration, pH value, total hardness, total dissolved solids, concentration of ammonia nitrogen, concentration of volatile phenol, iron concentration, lead concentration, and manganese concentration) about the sampled groundwater are above the standard for Grade-III groundwater. The values of certain unconventional indexes (for example, the concentration of aniline, 1,2-dichloroethane, methylbenzene, and benzene) are above the standard for Grade-III groundwater specified by Standard for Groundwater Quality. For details about groundwater monitoring results and evaluation of such results, refer to section 4.2 "Evaluation of Groundwater Pollution Status”

(1) Heavy metals As shown in Table 3.1-2, among the 8 heavy metal indicators of the site, only cadmium values did not exceed standards, while the measured values of the other heavy metals exceeded standards. Among these metals, the fold exceeding standards for copper and nickel were 16.58. Spatial analysis of nickel pollution status was conducted according to the soil monitoring results of the site. From Figure 3.1-2, we can see that samples with Ni values exceeding the screening values are mainly concentrated at 4m and above, with the maximum value appearing at 2.5 m of a sampling point. The reduction in nickel concentration with increasing depth is not significant. The distribution of nickel at the central and northwest parts of the site is consistent with the layout of berberine manufacturing plants. In addition, the nickel level around the Weihua company is also relatively higher. Overall, it was observed that heavy metal levels decrease with increasing soil depth. However, the heavy metal levels in samples from deep levels in some sampling points are relatively higher. This may be due to the combined effects of historical soil backfilling and disturbances due to relocation.

Figure 9Figure 3.1-1 Nickel soil distribution in site（>50mg/kg） (2) POP pollutants As shown in Table 3.1-3, among the POP pollutants within the site, β-Hexachlorocyclohexane, 4'-DDD, 4,4'-DDE, 4,4'-DDT, and 2,4'-DDT all had samples that exceed standards of more than 20% and above. Among these POPs, 4,4'-DDT has 42.86% of samples that exceed standards, and a fold of 142 while β-hexachlorocyclohexane had 55% of samples that exceed standards and a fold of 22. Spatial analysis of pollution status of β-hexachlorocyclohexane, 4'-DDD, 4,4'-DDE, 4,4'-DDT, and 2,4'-DDT was carried out according to the soil monitoring results of the site. As shown in Figure 3.1-2, samples where β-hexachlorocyclohexane was detected were concentrated at 4m and above. Samples where β-hexachlorocyclohexane values exceeded the screening values were mainly concentrated at 1.5m and above. Β-hexachlorocyclohexane distribution was more scattered and included the raw wastewater treatment zone at the northwest corner, workshop zone, quality control block, and research block. This may be caused by disturbances due to relocation.

Figure 103.1-2 Distribution of -hexachlorocyclohexane in the Site (> 0.2 mg/kg) As shown in Figures 3.1-3, 3.1-4 and 3.1-5, the spatial distribution of DDT, DDD, and DDE is basically the same in the site, specifically: 1) they are mainly distributed in the original DDT production area, the outdiffusion area is nearly 20,000 m2, and the maximum depth is 7 m; 2) they are concentrated in the west side of the site and close to the western boundary, they may be leakage from transport trucks historically, and the maximum depth is 3 m; 3) they are concentrated in Weihua company and the warehouse in the northeast corner, the maximum depth is approximately 2 m, and the existence of them may be due to demolition disturbance.

Figure 13Figure 3.1-5 Distribution of DDE in the Site (> 1.4 mg/kg) (3) PAHs

As shown in Figure 3.1-2, the concentration of benzoapyrene (BaP) and other PAHs (including tetraphene, benzo[b]fluoranthene, dibenz[a,h]anthracene, and indeno(1,2,3-cd)pyrene) all exceeds the specified limits. Specifically, the over-limit rate of BaP is up to 63.13%, 150.3 times as much as the specified limit. In accordance with Risk Evaluation Report on POP-contaminated Site of Northeast

General Pharmaceutical Factory, the distribution of PAHs ischaracterized in that high-molecular-weight PAHs play a dominant role and BaP is closely correlated with other PAHs. This is mainly due to that the PAHs are mainly generated due to the sedimentation after incomplete combustion of fossil fuels. The distribution of PAHs in the current site also shows the above characteristics.

As shown in Figure 3.1-6, the concentration of BaP obviously tends to decrease with the increase in soil depth. At each point position, the maximum concentration basically arises at the layer depth of 0.5 m. This shows that the BaP pollution in the site is mainly influenced by regional atmospheric sedimentation. In addition, there are many soil samples with an over-limit BaP concentration, and the BaP concentration universally exceeds the specified limit in different areas of the site. It should be noted that at one or two point positions, the BaP concentration is still high at the layer depth of 6 m.

As described in Table 3.1-2, among the VOCs in the polluted site, the over-limit rates of benzene concentration and chloroform concentration are respectively 32% and 37.5%. According to the soil monitoring results, spatial analysis is conducted in respect of benzene and chloroform pollution.

As shown in Figures 3.1-7 and 3.1-8, the soil samples whose benzene concentration exceeds the screening values are distributed at the depth of 0.5 to 4 m, and the soil samples whose chloroform concentration exceeds the screening values are distributed at the depth of 2 to 5 m. At point positions

29 and 35, the concentration of VOCs exceeds the specified limits. The two point positions are both located in the original DDT production area, which was subsequently changed into the berberine production workshop. This explains why the concentration of VOCs exceeds the specified limits.

The monitoring data on the groundwater within the remediation range is mainly available from

Risk Evaluation Report on POP-contaminated Site of Northeast General Pharmaceutical Factory, which was prepared by Shenyang Academy of Environmental Sciences in November 2017.

Shenyang Academy of Environmental Sciences has sampled the groundwater for three times. The first groundwater sampling was conducted on June 19th, 2017; six groundwater samples and one parallel sample (G2) were acquired. The second groundwater sampling was conducted on July 29th,

2017; G5 was sealed for unknown reasons, and thus the groundwater in G5 could not be sampled; then, five groundwater samples and one parallel sample (G6) were acquired. The third groundwater sampling was conducted on October 27th, 2017; G1, G4, and G5 were sealed for unknown reasons, and thus the groundwater in G1, G4, and G5 could not be sampled; then, three groups of groundwater soils (G2, G3, and G6) and one group of parallel samples (G2) were acquired. Figure

3.2-1 shows the groundwater sampling points, and Table 3.1-3 gives the basic data about groundwater sampling points.

3.2.3 Main Content of Polluted Site Remediation

According to Remediation Plan for the POP-contaminated Site (North Production Area of the

Factory in Bei'er Road of Northeast Pharmaceutical Group Co., Ltd.) of Northeast General

Pharmaceutical Factory, the treatment and remediation of the POP-contaminated soils involve seven heavy metals (including arsenic, copper, zinc, nickel, lead, chrome, and mercury), five PAHs

(including tetraphene, benzoapyrene, benzo[b]fluoranthene, dibenz[a,h]anthracene, and indeno(1,2,3-cd)pyrene), two types of POPs (including DDT, DDD, DDE and

-hexachlorocyclohexane), aniline, two VOCs (including benzene and chloroform), and TPH(< C16).

In the current land lot, there are 82 polluted point positions in total. Specifically, the pollution depth of

75 point positions is at least 1.5 m, and the pollution depth of five point positions is up to 5 m.

 In-situ remediation

The soils polluted by a single heavy metal (mainly Nickel) total up to 6,382 m3. The leaching concentration in the soils merely polluted by nickel is above the admission criteria of landfills. To control risks more effectively, however, it is necessary to stabilize all the soils polluted by a single heavy metal that surpass the standard for industrial lands. This work is carried out in the current site.

4. Technical Solution to Polluted Site Soil Remediation

4.1 Technical Roadmap According to the pollution features of the current site, results of technology screening and evaluation, and opinions of the interested parties, the polluted soils should be subjected to ex-situ remediation and excavation first, and then some soils should be transported to the new factory for use as backfill soils and other soils should be stabilized or subjected to chemical oxidation and thermal desorption. The details are as follows: (1) The polluted soils that surpass the standard for residential lands but fall short of the standard for industrial lands (excluding DDT-polluted soils) should be directly transported to the new factory for use as backfill soils; (2) The soils that are polluted by a single heavy metal and surpass the standard for industrial lands should be solidified and stabilized first, and then transported to Laohuchong domestic waste landfill for use as casing soils; after the stabilization treatment, the concentration of nickel should meet the admission criteria of the landfill; this work is carried out on site; (3) The soils polluted by PAHs, DDTs, and TPHs should be further subjected to a small-scale test and pilot-scale test if the degradation rate of 35% is enough to attain the remediation goal; if feasible, the soils should be subjected to chemical oxidation; chemical oxidation of the soils is intended to attain the target values for soils of industrial lands (or the target values of soils of residential lands if the soils are polluted by hexachlorocyclohexane); if the chemical oxidation reaches the specified standard, the soils should be backfilled in the new factory; this work is carried out on an ex-suit basis; (4) Other organically polluted soils or compositely polluted soils (primarily polluted by organic pollutants) should be subjected to thermal desorption; if chemical oxidation is not feasible, the associated soils should also be subjected to thermal desorption; the thermal desorption is intended to obtain residential lands; after the treated soils meet the specified standard, they should be discharged as residual soils; this work is carried out on an ex-suit basis.

Figure 30Figure 4.1-1 Technical Roadmap for Remediation and Treatment of Polluted Soils 4.2 Implementation Scheme of In-situ Remediation Engineering

4.2.1 Procedure of the Implementation Scheme

The polluted soils should be excavated primarily by mechanical means (specifically, by excavators), and secondarily by manual means. According to the construction condition, excavation requirements, and excavation quantity, it is necessary to arrange mechanical equipment and construction personnel reasonably in advance, and make various preparations as appropriate. To implement the excavation engineering correctly, it is necessary to measure, locate, and mark the polluted areas by lineation according to the remediation boundaries, and set up protective fences for the polluted areas. The polluted soils should be excavated by blocks and by layers. After a certain

(2) Construction Surveying

Surveying preparations are an important link for ensuring a smooth surveying process.

Surveying preparations include drawing review, hand-over and check of the reference points for surveying and positioning, check and calibration of test instruments, development of surveying program, data preparations, and measurement of construction sites. According to the scope of soil treatment and remediation determined in an earlier stage, we determined the coordinates of the inflection points of the scope of soil treatment and remediation by GPS, determined the excavation lines of foundation trenches, and marked the excavation lines by white ashes. On one side of the excavation lines, we set up a warning board, which indicated the types of soils, excavation depth, and treatment mode to prevent incorrect places from being excavated.

 Materials and Instruments

a. The surveying engineering mainly requires some sporadic and auxiliary materials, including white ashes, timber piles, small red flags ,and drawings;

b. The surveying engineering mainly requires three types of instruments: laser theodolite (JZ2), level gauge (DZS3-1), and TOPCO total-station instrument (N211D);

c. The used tools mainly include 5m small flexible rules, 50m steel measuring tapes, leveling rods, and level rulers.

 Sloping of Foundation Pit

The maximum excavation depth is 4 m below the ground; at the depth of 2 to 4 m, the excavation area is very small; there are no important buildings at the slope top, and sloping is permitted by site conditions. Therefore, the natural sloping mode is used for the protective slope of the foundation pit.

The protection of the foundation pit should meet the following requirements: a. in the process of soil excavation, personnel and equipment should stay away from the foundation pit, to prevent the occurrence of accidents; b. around the positions 0.6 m away from the pits, two protective railings are set up by using φ48 steel pipes, the upright pole interval is 4 m, the upright poles are 1.2 m above the natural terrace, and the burial depth of them is 0.5 m. Within the distance of 1 m to the sides of the upper opening of the foundation pit, no soils, materials, machines and tools may be placed; the construction personnel should not climb over the protective railings; in the process of foundation pit excavation, warning boards should be set up, and red lamp signs should be set up in the nighttime; c. the construction personnel outside the foundation pit should not throw anything into the foundation pit, and when tools are transferred to the foundation pit, the transferring personnel should release their hands only after the tools are held firmly by the recipients; d. when having a rest, the personnel in the Shenyang Lvheng Environment Consulting Co. Ltd 102 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site foundation pit should stay away from the pit sides and sloping positions; e. the construction machinery should obey the command, the construction personnel should stay away from the construction machinery; if necessary, the operation personnel should be notified first, and other personnel should not get close to the construction machinery unless they receive the response of the operation personnel; f. in the process of construction, the construction personnel should keep a close watch on weather changes, and take appropriate measures to prevent large-area soil collapse.

(3) Infrastructure Construction

It is necessary to set up continuous fences with a height of at least 2.5 m, implement the engineering in a closed manner, and ensure not only environmental sanitation and civilized construction, but also easy entry and exit and smooth traffic.

In the remediation site, office buildings and life buildings should be arranged on the principle of reasonable layout, compactness and orderliness, and civilized construction, and the remediation site should be separated from office buildings and life buildings.

A water drainage system should be set up, and the wastewater from truck cleaning should all be reused. Figure 2 attached shows the position of the truck washing station.

(4) Soil Excavation

The polluted soils should be excavated primarily by mechanical means and secondarily by manual means. According to the construction condition, excavation requirements, and excavation quantity, it is necessary to arrange mechanical equipment and construction personnel reasonably in advance, and make various preparations as appropriate.

For the current engineering, the soils to be excavated amount to 114,000 m3 approximately. As planned, 1,900 m3 soils need to be excavated per day, and the whole excavation work will take 60 days approximately. The excavation capacity is 800m3 per day, which is enough to complete the daily excavation task. Table 4.2-2 describes the mechanical equipment required for soil excavation. Table 47Table 4.2-2 Equipment Required for Soil Excavation Mechanical Equipment Specification and Model Quantity Excavator Capacity of grab bucket: 0.6 to 1 m3 4 Truck Truck capacity: 6 to 8 m3 6

In the remediation site, up to 113 foundation pits need to be excavated in order of "slight pollution first and then heavy pollution..” For the slightly polluted land lots, the planned quantity of soils should be excavated; for the heavily polluted lands, a larger quantity of soils should be excavated than Shenyang Lvheng Environment Consulting Co. Ltd 103 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site planned, to reduce the impacts on the ambient environment. Once the heavily polluted soils are disturbed, organic pollutants will be volatilized to influence the ambient environment. According to the pollution scope of each foundation pit, the polluted soils should be excavated layer by layer.

Specifically, the first soil layer is 0 to 0.5 m in depth, the second soil layer is 0.5 to 1.0 m in depth, the third soil layer is 1.0 to 1.5 m in depth, the fourth soil layer is 1.5 to 2.0 m in depth, the fifth soil layer is

2.0 to 2.5 m in depth, the sixth soil layer is 2.5 to 3.0 m in depth, and the seventh soil layer is 3.0 to

4.0 m in depth. When each layer of polluted soils is excavated, it is necessary to control the pollution boundary and depth of the soils. After each layer of soils is excavated, the next layer of polluted soils is surveyed, positioned, and excavated continuously.

(5) Temporary Storage of Polluted Soils

The polluted soil temporary storage area includes a total of temporary storage area of the original contaminated soil and temporary storage of polluted soil, of which the original temporary storage area for contaminated soil is located in the middle of the contaminated site and covers an area of 1000 m2, which is mainly used for storage Tiexi district government land use risk assessment of soil contamination identified heavily contaminated soil; this temporary cleaning of contaminated soil in the northern part of the plant area, covers an area of about 3000m2, mainly for the project of clearing contaminated soil. At present, the surface of the soil temporary storage area has been hardened.

After communicating with the construction unit, different subareas will be set up in the temporary storage area of the soil, that is, the temporary storage area of heavy metal contaminated soil, the temporary storage area of organic contaminated soil and the temporary storage area of complex contaminated soil, Dig soil temporary storage area. Different types of temporary storage area to be well isolated and the identification plate, dredged contaminated soil by pollutants were loaded on different vehicles directly transported away, not in the field of temporary storage. Contaminated soil temporary storage area schematic diagram shown in Figure 4.2-2.

(6) Solidification and Stabilization Technology Curing stabilized soil repair process as shown in Figure 4.2-3.

Figure 4.2-3 heavy metal contaminated soil repair process flow chart

The process is summarized as follows:

⑴ site excavation

Polluted soil excavation using mechanical removal, supplemented by manual methods. According to the construction conditions, excavation requirements and removal of contaminated soil, reasonable arrangements should be made for the number of mechanical equipment and personnel prior to construction and preparation for all aspects. In the excavation, based on the on-site monitoring data, the on-site configuration of real-time detection equipment real-time detection of heavy metal pollutant concentrations in various polluted areas, to provide online data feedback of excavation area, and timely find areas inconsistent with the requirements of the excavated area.

⑵ contaminated soil pretreatment

Shenyang Lvheng Environment Consulting Co. Ltd 105 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Using crushing, screening machine to crush the soil, screening. Prior to soil treatment, screening and crushing should be carried out to eliminate construction waste. First, the use of excavators for large boulders screening, followed by the use of screening crushing bucket for fine screening and crushing, to ensure the follow-up treatment requirements. After crushing to ensure that 90% of the soil particle size does not exceed 30mm above the particle size before entering the stabilization process, to ensure the stability of the treatment effect.

Heavy metal contaminated soil in the production line before screening, broken. According to the restoration program This project is expected to use the international advanced professional construction machinery site screening broken. The versatile mobile screening crusher bucket is a worldwide patented product invented in the 1980s. It can be used in conjunction with general purpose loaders and excavators. It is easy to move and has no selectivity for the material to be treated. The process of the past complex soil sieving and crushing work is simplified to complete within one step, the scene is convenient and can achieve soil screening, crushing, mixing, mixing and other operations.

In the soil remediation project, firstly, the screening and shovel shovels are used to screen the polluted soil, remove the debris such as stones and construction rubbish, and simultaneously crush the contaminated soil to reduce the particle size of the soil as a pre-treatment device. The equipment is highly efficient. Its patented knife plate design ensures that the upper and lower staggered fixed blades guarantee the consistency of the finished product when it is inverted. Large-diameter rollers and cutter heads ensure that the material has good fluidity. The shaft can be continuously rotated in both directions and efficient torque transfer ensures robust start-up and operation, which is currently being used in several large soil remediation projects in the country.

The equipment is used to stabilize the soil management efficiency of 500-600 square / Taiwan class / pass, in order to fully mix the soil and pharmaceutical, mixing is expected to not less than 3 times. In the stabilization process, for the convenience of maneuverability, VL high-speed ectopic soil treatment equipment is also used to mix the stabilizer with the soil, and the equipment is used to treat the heavy metal-contaminated soil.

The device comes with 50 t solid state drug storage container and 1750L liquid reagent tank, according to the needs of the project circumstances, the external connection of other drug containers.

Soil treatment capacity up to 400t / h; depending on soil conditions may be. VL devices are non-stationary devices that can be moved from one site to another with short installation verification Shenyang Lvheng Environment Consulting Co. Ltd 106 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site time. The VL device comes with a diesel generator and requires less than 600L of diesel fuel to operate in 24 hours. Equipment for easy cleaning and maintenance. Curing stabilization integration device is shown in Figure 4.2-4.

The solidification and stabilization technology is to combine the heavy metal polluted soils with specific binders, so that the heavy metals in soils are immobilized by the binders and are kept in a steady state over a long period, thus reducing their migratory aptitude. The solidification and stabilization technology is universally used for quick control and remediation of heavy metal pollution of soils, and has an obvious advantage in treating the soils polluted by multiple heavy metals. The EPA of the U.S.A. refers to the solidification and stabilization technology as the optimal technology for treating the toxic wastes.

The solidification and stabilization technology includes two steps: stabilization and solidification.

Specifically, stabilization is to transform pollutants into difficult-to-dissolve forms of matter with lower migration ability or toxicity, to make the pollutants harmless and reduce their hazardous risks to the ecological system. Solidification is to microscopically wrap the pollutants into waterproof or low-permeability inert solid materials through physical actions, and transform the pollutants into difficult-to-dissolve forms of matter with lower migration ability or toxicity by reducing the area or amount of contact between the pollutants and solutions, in order to make the pollutants harmless and reduce their hazardous risks to the ecological system.

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site ectopic soil treatment equipment is also used to mix the stabilizer with the soil, and the equipment is used to treat the heavy metal-contaminated soil.

The BH stabilizing agent used in this project is a kind of active agent added to the soil. The main raw materials are ferrous sulfate, sodium citrate, potassium dihydrogen phosphate, lime and high molecular organic stabilizers. BH agents are used to regulate the physicochemical properties of soil and to immobilize toxic heavy metals in the soil by a series of reactions such as adsorption, precipitation, ion exchange, humification, oxidation-reduction, or to convert heavy metals into chemically inactive Morphology, reduce its bioavailability, thus preventing the migration of heavy metals, so that its leaching concentration was significantly reduced, no longer migrate to the surrounding environment.

⑷ soil conservation after disposal

The soil treated by the soil remediation equipment is transported to a set temporary soil remediation area for maintenance and testing. Heavy metal contaminated soil conservation time is

5-7d. To be protected soil in accordance with the different levels of pollution were stacked into a long pile of soil and soil moisture content of water adjusted to about 20% after the coverage with the dust network for conservation.

⑸ soil testing and acceptance after repair

Two samples were selected for testing after each soil treatment. The heavy metal leaching content (conventional 8 heavy metals) was analyzed. The pretreatment method was "acetic acid buffer solution leaching method for solid waste leaching toxicity" (HJ / T 300-2007) Standard is

"Groundwater Quality Standard" Class III limit.

⑹ the whereabouts of soil after treatment

After treatment, the soil was accepted and passed to Tiger Landfill for soil cover. The landfill site was used according to the relevant requirements of the Control Standard for Domestic Landfill

Contamination.

(7) Transport of Polluted Soils

The excavated polluted soils are mechanically loaded into trucks or dumpers. The soils excavated in the daytime are stored in the appropriate temporary storage areas according to the types of soil pollution, and are transported in the nighttime. The transport trucks should be marked with the types of soil pollution, and transport the corresponding types of polluted soils. A transport Shenyang Lvheng Environment Consulting Co. Ltd 108 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site truck should not be loaded with different types of polluted soils. In accordance with Remediation Plan for the POP-contaminated Site (North Production Area of the Factory in Bei'er Road of Northeast

Pharmaceutical Group Co., Ltd.) of Northeast General Pharmaceutical Factory, the excavated polluted soils should all be transported to the new factory for remediation, and travel through

Zhonggong North Avenue, Shenda Road, Honghu Avenue, Kaifa Road, Xihe 7 North Avenue, and

Shenxi 6 East Road to the new factory. The transport distance is 23 km, and the transport route is shown in Figure 5.1-3. In principle, the transport route should keep away from densely populated areas (such as residential areas, schools, and hospitals) and drinking water source protection areas.

A temporary soil storage zone (area: 10,000 m2) should be set up in the new factory. In the to-be coal yard in the southern part of the new factory, there is a 7,000 m2 workshop building with some feeding facilities, which can be used as the main workshop for soil treatment. In the northern part of the new factory, there is a 3,500 m2 vacant space, which can be used for turnover and temporary storage of polluted soils. In the southwestern part of the new factory, there is a to-be 15,000 m2 engineering area, which can be used as the backfill area for the soils that meet the standards for industrial lands. Judging by the depth of 2 to 2.5 m, the engineering area is estimated to accommodate 30,000 to 40,000 m3 soils. The new factory is well-enclosed, and is surrounded by

Qianma Village, Sanmangniu Village, and Yuejia Village, which are all in process of demolition and resettlement. Yuhong District's Social Welfare Home is located to the south of the new factory, and its minimum distance to the new factory is 2,190 m (the distance between them is very long). Therefore, the new factory is suitable to serve as the remediation site for polluted soils. The remediation engineering of the site is experiencing environmental impact assessment.

Judging by the excavated soil quantity (114,000 m3) and excavation duration (60 days), the excavation speed is approximately 1,900 m3/d. DFL3241 trucks or transport trucks of similar model will be used. One truck can transport 20 m3 soils every time, one round trip will take 2 hours, and one truck can have four round trips per day. Therefore, a total of 20 transport trucks are required.

Figure 34Figure 4.2-4 Transport Route of Polluted Soils 4.2.2 Primary Pollution Sources and Environmental Impact Analysis

4.2.2.1 Waste Gas

1. Construction Dust

In the in-situ remediation site, fugitive dust is generated in the process of soil excavation, temporary storage of soils, and operation of construction trucks. In addition, road dust is generated by the transport trucks. The evaluated engineering content is the soil excavation of the polluted site, which is similar to the construction content of general construction projects. Therefore, the evaluation of construction dust shows an analogy to the construction dust test for general construction projects.

Table 4.2-3 lists the results of construction dust test under five different construction conditions of Shenyang City. During the test, the wind speed is all lower than 2.4 m/s. Table 48Table 4.2-3 Data on Analogue Test of Construction Dust (Unit: μg/m3) No. of TSP Const Upwind direction Downwind direction Within the ructio 50 m construction site 50 m 100 m 150 m n Site 1 327.0 624.0 484.0 356.0 332.0 2 313.0 594.0 431.0 372.0 311.0 3 327.7 594.0 476.0 390.0 322.0 4 325.0 766.0 514.0 367.0 336.0 5 295.0 413.0 392.0 326.0 303.0 According to this table, the TSP concentration within the construction site is the highest, the TSP

Shenyang Lvheng Environment Consulting Co. Ltd 110 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site concentration in the upwind direction is relatively low, and the TSP concentration in the downwind direction gradually decreases with the increase in distance. The range of influence from fugitive dust is not more than 200 m.

According to field investigation, the east of the polluted site is adjacent to Vanke Spring Dew

Mansion, its south is adjacent to Bei'er West Road, its west is adjacent to Tiexi District People's

Government of Shenyang City, and its north is adjacent to Xiaobei 1 West Road. Specifically, the polluted site is 20 m and 10 m away from the residential community (Vanke Spring Dew Mansion) and office building of Tiexi District People's Government of Shenyang City, so they are susceptible to fugitive dust.

In-situ remediation of the polluted site is estimated to be completed by the end of June 2018.

Before the commencement of each stage of soil treatment engineering, it is necessary to set up continuous fences with a height of 2.5 m or more around the remediation site, to prevent the escape of fugitive dust. Across the whole process of soil remediation, it is necessary to spray water to suppress construction dust. The different areas in the temporary storage zone of polluted soils should be covered, and the soil remediation zone (by solidification and stabilization) should be fitted with a closed membrane structure shed (or the polluted soils should be treated by integrated machines in a closed manner). The whole remediation engineering should be implemented in a closed environment.

In the process of soil excavation and loading, dust can be decreased by reducing the operation speed or drop. The above measures serve to reduce the concentration of TSP in air significantly and alleviate the dust pollution in the construction site effectively; in addition, construction dust will disappear immediately at the end of engineering construction. Therefore, the implementation of the remediation engineering will not influence the people in Vanke Spring Dew Mansion and Tiexi District

People's Government.

2. Volatile Organic Pollution Gas

In the in-situ remediation site, the volatile organic pollution gas is mainly sourced from the polluted soils. In the polluted soils, there exist such pollutants as PAHs and organochlorine pesticides, and in the soils of certain polluted areas, there exists an obvious hexachlorocyclohexane smell. The soil excavation process easily gives off the irritating smell. However, it is difficult to quantitatively analyze and determine the components and concentration of organic substances in soils. Therefore, it is also difficult to determine the concentration of waste gas pollutants discharged during soil Shenyang Lvheng Environment Consulting Co. Ltd 111 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site excavation. Soil excavation is estimated to take 25 days (the construction period is very short), and the excavated soils will be transported instantly rather than be stored in the current site for a long period. In addition, the polluted soils in the polluted site will all be excavated and transported to other places. Therefore, the volatilized organic pollutants are very limited, and the impact on the ambient environment is slight.

4.2.2.2 Wastewater

The wastewaterwastewater generated in the process of engineering construction mainly includes the flushing water for the wheels of transport trucks and domestic wastewaterwastewater produced by the construction personnel. The current engineering is not implemented in rainy season, so foundation pit water will not be involved.

1. Flushing water for the construction trucks

The remediation engineering is estimated to take 90 days. The consumption standard of flushing water is 0.3 t per truck-time, so the required quantity of flushing water is 28.8 t per day. The wastewaterwastewater produced by truck flushing will all return to the settling pond for cycled use, but will not be discharged to the ambient environment.

2. Domestic wastewater produced by the construction personnel

In the construction site, there are 30 construction personnel. The engineering construction period is 90 days; the consumption standard of domestic water is 50 L per person-day. Then, the required amount of domestic water is 1.5 t/d (or 135 t/a). Assume that the discharge of wastewater is approximately 85% of domestic water consumption; then, the discharge of wastewater is 1.275 t/d (or

114.75 t/a). The discharge quantity of domestic wastewater is very small. The domestic wastewater is discharged to the existing septic tank of the factory, and then transported to a sewage treatment plant through the sewage pipe network. The water quality of the discharged domestic water should comply with the requirements specified in Table 2 of Comprehensive Sewage Discharge Standard of Liaoning

Province (DB21/1627-2008). The discharged domestic wastewater will not pollute or influence the surface water and groundwater if appropriate anti-leakage and anti-seepage measures are taken for sewage treatment facilities.

The noises during engineering construction are mainly generated by machines at the time of site leveling and soil excavation and transport. The intensity of such mechanical noises is usually 75 to 85 dB(A), as described in Table 4.2-5. Table 50Table 4.2-5 Construction Equipment and Noise Source Intensity Noise Intensity No. Machine Quantity Discharge Mode (dB(A)) In the daytime, 1 Compactor 4 80 intermittent In the daytime, 2 Small loader 10 85 intermittent In the daytime, 3 Pushdozer 5 80 intermittent In the daytime, 4 Excavator 10 80 intermittent In the daytime, 5 Dumper 20 75 intermittent In the daytime, 6 Vibratory roller 1 85 intermittent In the daytime, 7 Integrated agitator 1 80 intermittent The same reception point can receive the acoustic energy transmitted by multiple acoustic source points.

The solid wastes generated during engineering construction mainly include the excavated polluted soils and a small quantity of domestic wastes generated by the construction personnel. In accordance with Remediation Plan for the POP-contaminated Site (North Production Area of the

Factory in Bei'er Road of Northeast Pharmaceutical Group Co., Ltd.) of Northeast General

Pharmaceutical Factory, the quantity of soils to be excavated will be 70,171 m3. Some of the excavated soils will be transported to the new factory for remediation; some of them will be subjected to in-situ remediation first and then transported to Laohuchong domestic waste landfill for use as casing soils; the suspected unpolluted 24,888 m3 soils will be transported to the new factory for treatment. The domestic wastes generated by the construction personnel will be approximately 0.13 t/a, and will be transported and disposed by the environmental sanitation authorities. Table 4.2-6 describes the generation of solid wastes.

4.2.3.1 Solutions and Measures for Air Pollution Control

Fugitive dust will be generated in the process of soil excavation. The soil remediation organization should strictly abide by the instructions specified in Notice of the Environmental

Protection Bureau of Shenyang City on Dust Pollution Control and Emergency Notice on

Strengthening Dust Pollution Control, and take the following anti-dust measures:

1) Before the commencement of each stage of soil treatment engineering, set up continuous fences with a height of 2.5 m or more around the remediation site, to prevent the escape of dust during soil excavation and remediation.

2) Spray water fog through mobile spraying and de-dusting machines to prevent the escape of dust.

Figure 35Figure 4.2-5 Mobile Spraying and De-dusting Machine 3) It is recommended that the soil remediation zone (by solidification and stabilization) should be fitted with a closed membrane structure shed (or the polluted soils should be treated by integrated Shenyang Lvheng Environment Consulting Co. Ltd 115 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site machines). The polluted soils should be agitated and crushed in a completely closed environment, to reduce the diffusion of fugitive dust effectively.

4) The polluted soils in the temporary storage zone should all be covered by rain-proof tarpaulins or membranes, but should not be exposed to the air. Meanwhile, the rain-proof tarpaulins should be fixed, to prevent them from being blown off by wind and prevent the diffusion of fugitive dust.

5) If engineering construction is made impossible due to adverse weather (such as strong wind and heavy rain), the naked soils should be covered by rain-proof cloths, thus preventing dust diffusion or rain washing, as well as secondary pollution.

6) After soil excavation is complete, it is necessary to approach the land developer. The excavation site should not be exposed to the air, thus preventing the diffusion of fugitive dust.

7) In the process of soil excavation and loading, it is necessary to reduce the operation speed and drop, thus preventing the generation of fugitive dust.

8) The transport trucks should be covered by canvases, not leak any soils, and discharge exhaust gas as little as possible.

9) The transport passageways should be cleaned frequently, and the speed of incoming/outgoing trucks should be controlled, to reduce the generation of fugitive dust.

10) It is necessary to strengthen the management of soil excavation and transport, speed up soil excavation and transport, load/unload the excavated soils reasonably, ensure standardized operations, and reduce the scope of influence from fugitive dust.

11) The construction machines and transport trucks should be overhauled and maintained carefully, and it is prohibited to use the trucks that go beyond their useful life and the trucks whose exhaust emissions exceed the allowed limits. The transport trucks should be fitted with exhaust purifiers, and standard-compliant fuels rather than inferior fuels should be used, to reduce the emissions of harmful gas. All motor vehicles should be subjected to regular exhaust emission test by the qualified institutions authorized by the environmental protection authorities of Shenyang City, and be granted environmental conformance marks.

4.2.3.2 Solutions and Measures for Water Pollution Control

The wastewater generated during soil excavation mainly includes the flushing water for the wheels of transport trucks and domestic wastewater generated by the construction personnel. The Shenyang Lvheng Environment Consulting Co. Ltd 116 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site following measures should be taken to prevent the secondary pollution from the wastewater:

1) The depth of groundwater in the construction site is 6 to 7 m. The excavation depth should be not more than 5 m, and soil excavation should not be implemented in rainy season. Therefore, foundation pit water is not involved.

2) The domestic wastewater generated by the construction personnel may be discharged to the septic tank in the south of Northeast General Pharmaceutical Factory, then treated in the septic tank, and finally discharged to Xiannvhe Sewage Treatment Plant for centralized treatment.

3) A truck washing station should be set up near the egress of transport trucks, to wash the construction machines and transport trucks. Before leaving the construction site, each transport truck must have its wheels and body washed thoroughly, thus preventing the polluted soils from being brought out and consequently preventing secondary pollution. The truck washing station should be fitted with washing platforms, pumps, and pipes, and drainage ditches should be set up around the truck washing station. The wastewater from truck washing should be discharged to a settling pond through pipes, be precipitated in the settling pond, and finally be reused.

4) The four walls and bottoms of the settling pond, temporary soil storage zone, solidification and stabilization area, and truck washing station should all be subjected to anti-seepage treatment, and the wastewater pipes should also be subjected to anti-seepage and anti-leakage treatment. The anti-seepage grade should meet the requirements specified in Article 6.3.1 of Standard for Pollution

Control on Hazardous Waste Storage (GB18597-2001).

Key anti-seepage areas: HDPE or other artificial materials with a thickness of at least 2 mm should be used, and the permeability coefficient should be less than or equal to 10-10 cm/s.

Anti-seepage treatment for wastewater pipes: High-strength and highly anti-corrosion pipe materials (such as seamless steel tubes) and high-grade anti-rot materials should be used; welding connection should be used.

It is recommended that HDPE geotechnical membranes (the permeability coefficient is as low as

10-12 to 10-13 cm/s) should be used in the key anti-seepage areas. The HDPE geotechnical membranes have the following features and advantages:

Low permeability: The permeability coefficient is very low, and is far lower than the standard specified by the related specifications. This ensures that the wastewater contained in the settling pond and generated by the truck washing station will not seep, thus protecting the groundwater and Shenyang Lvheng Environment Consulting Co. Ltd 117 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Chemical stability: Compared with other geotechnical membranes, HDPE geotechnical membranes have exceptional chemical stability, and will not be corroded by ordinary wastewater or other substances.

Ultraviolet stability: HDPE membranes have high anti-ultraviolet and anti-aging properties. The carbon black contained in the HDPE membranes provides an enhanced anti-ultraviolet and anti-ozone capability. In addition, no plasticizers are used in the production process of HDPE membranes. Therefore, they can be exposed to sunshine for a long period, and maintain the original properties in a high-temperature environment (specifically, the organic substances will not be decomposed).

High technological maturity: The production technology of HDPE membranes have been matured, and a perfect supporting welding method is available. The high technological maturity facilitates engineering construction. Many success examples show that HDPE membranes are the host material of the anti-seepage layer.

High cost performance: High cost performance makes HDPE membranes suitable to China's actual condition and economic development level of different regions.

5) The wastewater from truck washing should all be reused, but not be discharged to the outside environment. In the planning and design stage, the soil remediation organization should further optimize the wastewater treatment facilities, construction scale, and wastewater reusing scheme, to ensure that all wastewater can be reused.

6) A groundwater environment monitoring system should be built to keep abreast of the quality of groundwater in the region and give early warnings about the groundwater, thus taking preventive and protective measures promptlypromptly. The observation instruments at the monitoring points should be maintained promptlypromptly, to ensure uninterrupted observation for a long period.

4.2.3.3 Solutions and Measures for Noise Pollution Control

The noises during soil excavation are mainly sourced from the excavation equipment, transport trucks, integrated agitators, and soil improvement machines. The following measures should be taken to prevent the noise pollution during soil remediation:

1) During engineering construction, noise emissions should not exceed the limits (70 dB in the daytime, and 55 dB in the nighttime) specified by Emission Standard of Environment Noise for Shenyang Lvheng Environment Consulting Co. Ltd 118 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Boundary of Construction Site (GB 12523-2011).

2) It is advisable to use the construction equipment that emit low noises or are fitted with soundproof or noise reduction devices.

3) The strong-noise equipment should be closed or blocked by sound-proof shields, to reduce the noises.

4) Increase public awareness on environmental consciousness, take effective measures to control the man-made construction noises, strengthen construction management, and minimize the disturbance of noises to people.

5) The construction personnel nearby the high-noise equipment should wear earplugs, work by shifts. or have their working hours shortened, to reduce the harm of noises to their ears.

6) Construction operations should be scheduled reasonably, and construction operations should be prohibited during the period of 22:00 to 6:00 of next day. If nighttime construction is necessitated, it is necessary to obtain prior approval of the authorities concerned and the consent of the surrounding residents.

4.2.3.4 Solutions and Measures for Solid Waste Pollution Control

The solid wastes generated during engineering construction mainly include the remaining buildings in the original site, excavated polluted soils and a small quantity of domestic wastes generated by the construction personnel. The following measures should be taken to prevent the possible pollution arising from the solid wastes:

(1) When excavating each land lot, it is necessary to distinguish different types of polluted soils on site. Each type of polluted soils should be excavated thoroughly, and it is not advisable to mix the heavily polluted soils with the slightly polluted soils or mix different types of polluted soils. Otherwise, this will increase the workload in excavation of heavily polluted soils, and subsequent treatment costs.

Different excavators should be arranged to suit different types of polluted soils, thus preventing cross pollution.

(2) In the temporary soil storage zone, classification labels should be set up in the boundaries between different areas (including the temporary storage area for the soils to be remediated, maintenance area for the remediated soils, temporary storage area for the soils to be directly transported, and temporary storage area for the soils to be accepted), thus facilitating sorted loading/unloading and transport. In addition, lattice blocks should be set up, to prevent the mixing of Shenyang Lvheng Environment Consulting Co. Ltd 119 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

(3) While the polluted soils are temporarily stored, eye-catching warning signs should be set up around the temporary storage zone, and be managed by specialized personnel. Routine patrol should be strengthened, unexpected events (if available) should be handled promptlypromptly, and safety accidents and secondary pollution should be prevented.

(4) After the soil remediation engineering is complete, the soils in the temporary soil storage zone and soil remediation zone should be sampled for test, to prevent the polluted soils from polluting the existing unpolluted soils.

(5) The excavation and transport personnel should be trained in advance. In the process of soil excavation and transport, specialized personnel should be assigned to supervise and record the progress and truck information, thus ensuring that the excavation quantity and transport quantity are well documented. It is necessary to define detailed managerial and technical requirements for soil excavation and transport, follow the excavation and transport schedule, and strengthen process management, thus preventing the negative influence on the ambient environment.

(6) The polluted soils destined for Laohuchong domestic waste landfill should be transported immediately once they are excavated, but should not be stored in the temporary soil storage zone for a long period.

(7) The domestic wastes generated by the construction personnel should be transported and be subjected to innocent treatment by the environmental sanitation authorities, thus preventing negative influence on the ambient environment.

(8) The remaining building wastes of the original site should be buried in a special building waste landfill, but should not be transported at will.

(9) The transport trucks should be marked correctly according to the types of polluted soils, and different types of polluted soils should be transported by different trucks, thus preventing cross pollution. The same truck should not transport different types of polluted soils.

(10) For each truck of polluted soils to be transported, it is necessary to fill in a transfer form in several copies, which contains such data as the time of departure, pollution type, transported weight, responsible person for transport, responsible person for reception, place of reception. The multiple copies will be respectively delivered to the production organization, transport organization, receiving organization, environmental protection authorities of the source place, and environmental protection Shenyang Lvheng Environment Consulting Co. Ltd 120 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site authorities of the destination. After polluted soils reach the destination, the responsible person for reception should inspect the polluted soils as per the transfer form, enter the date of receiving, and append the official seal. The transport route of polluted soils should bypass residential areas, schools and sensitive areas (such as source areas of surface water and groundwater), and should be transported through an optimal route that offers good road condition and is able to completely bear the load of heavy-duty trucks.

(11) The soils involved in the remediation engineering are polluted soils, so they should be covered well to prevent secondary pollution. The transport trucks should have high performance and well-enclosed carriages, obtain all required certificates, and run along the specified route. During the transport process, the transport trucks should not leak soils. The loading height should not outreach the baffle grooves, and should be 5 cm below upper sides of baffle grooves. At the bottom of the carriage, a HDPE membrane (thickness: 0.7 mm) should be laid, and the upper part of the carriage should be covered by a tarpaulin. The HDPE membrane should be tied with the tarpaulin, thus providing a double closing environment. In the rear part of the groove, a color strip cloth should be laid, thus preventing the soils from leaking to roads through the gaps of the truck body. The transport trucks should be clean and well-enclosed, thus ensuring the closedness of soils in transit and preventing the diffusion of fugitive dust fully.

(12) At the egress of the polluted area, truck washing facilities should be set up. Before each truck leaves the polluted area, its wheels should be washed and the residual soils on the truck body should be flushed away. The wastewater from truck washing should be gathered in the truck washing station and then treated centrally. Otherwise, the truck may carry away polluted soils, thus causing secondary pollution.

(13) The whereabouts of polluted soils should be strictly controlled, the entry and exit of transport trucks should be confirmed, and specialized personnel should be assigned to patrol the polluted soils in transit, thus ensuring that all polluted soils are transported to the specified destinations.

(14) In the process of site remediation, a balance of cut and fill must be ensured on site, and no soils in any area may be transported outwards.

(15) In the process of soil excavation, it is necessary to take notice of the remaining abandoned pipes or other suspicious pollutants in the original site. In the north of original Northeast General

Pharmaceutical Factory, there exist some abandoned underground pipes. Due to its production Shenyang Lvheng Environment Consulting Co. Ltd 121 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site technologies, some organic pollutants still remain in the abandoned underground pipes. Once such pipes are damaged, secondary pollution will be caused. During soil excavation, some staffs of original

Shenyang Gourmet Powder Factory must be present to position the underground pipes and other suspicious pollutants accurately, in order not to damage such pipes. The excavation personnel should operate with care. Once underground pipes or other suspicious pollutants are found, the excavation personnel should stop soil excavation immediately and report to the authorities concerned.

4.2.3.5 Solutions and Measures for Risk Prevention

The organic pollutants involved in the soils of the current site are highly poisonous and severely harmful to human body. They may bring about health risks through respiration, contact, or oral intake.

Therefore, in the process of polluted site remediation, it is necessary to abide by the related regulations of PRC, take anti-risk measures, and formulate an emergency plan against risks, to ensure the health and safety of field personnel.

The risky pollutants encountered in the process of soil excavation, transport, and remediation mainly include tetraphene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzoapyrene, indeno(1,2,3-cd)pyrene, dibenz[a,h]anthracene, and -hexachlorocyclohexane. The nearby residents may complain if unexpected events occur, unidentified pipes, structures, or liquids are found, and peculiar smell is diffused.

● Anti-risk Measures

1. Risk Control in the Process of Polluted Soil Excavation

(1) Control the excavation operation plane, and reduce the volatilization area of pollutants.

(2) Alleviate soil disturbance, and reduce the escape of pollutants. In the process of polluted soil clean-up, digging buckets should be operated steadily, and it is prohibited to throw polluted soils at a long distance or throw polluted soils to transport trucks from a very high position. When polluted soils are loaded into transport trucks, digging buckets should be as close to the truck bodies as possible.

(3) Control the excavation time, and reduce the volatilization temperature. To reduce the volatilization of pollutants, it is advisable to excavate soils in the nighttime and in a low-temperature season.

(4) Control fugitive dust, and reduce the diffusion of pollution. It is necessary to take various pollution and risk control measures, for example, spray water on the roads, control the speed of transport trucks and number of trucks in the excavation site, cover the operation plane by tarpaulins, Shenyang Lvheng Environment Consulting Co. Ltd 122 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

2. Risk Control in the Process of Polluted Soil Transport

(1) The transport trucks should have excellent enclosures, and possess a satellite positioning function.

(2) After soils are loaded into transport trucks, the soils should be covered by tarpaulins tightly, and are not allowed to leave the site unless it passes the checks.

(3) Specialized personnel should be assigned to patrol the transport trucks. If they find that tarpaulins are blown off by wind, they should immediately notify the drivers to pull over and have the soils covered well.

(4) Mobile pollutant monitoring devices should be provided to monitor the ambient air along the transport route, thus ensuring that the air quality along the transport route complies with the related standards of PRC and Liaoning Province.

3. Risk Control in the Process of Temporary Storage and Remediation of Polluted Soils

(1) Preferably, the polluted soils should be remediated in the negative-pressure and sealed sheds.

(2) The incoming/outgoing polluted soils to/from the temporary soil storage zone should meet the foresaid risk control requirements in respect to excavation process of polluted soils.

(3) The polluted soil remediation equipment workshop should be provided with pollutant auto-monitoring devices and alarm devices, thus ensuring that the pollutant concentration of the air in the workshop does not exceed the allowed limits.

● Emergency Measures Against Risks

The excavation personnel should not continue soil excavation unless it is confirmed that the pipes or structures are abandoned and potential safety hazards are eliminated. If unknown materials are found, such materials should be identified by the qualified institutions. If such materials are identified as hazardous wastes, they should be sent to the hazardous waste center for disposal.

2. Emergency Plan against Major Pollution Accidents on the Excavation Site

During the process of site excavation, the organic pollutants in the soil emit a large amount of smells, and the site operators should suspend the construction and promptly evacuate the site in the upwind direction and immediately report to the on-site emergency response team.

The on-site emergency team received the report detailing the time, place, causes, sources of pollution, major pollutants, scope of pollution, casualties, contact person and contact information of the incident in detail. The on-site emergency team should rushed to the scene to make preliminary judgments The degree of harm of the incident, take appropriate measures; odor lighter, no casualties, should be promptly prepared with pre-prepared cloth will disturb the soil and strict warning, and set the warning signs. After confirming that there is no abnormal smell on site, construction can continue.

When the odor is distributed seriously and there is obvious discomfort in the body of the staff, rescue should be organized immediately and report to the competent department of environment at the same time. Specific measures are as follows:

⑴ responsible for the construction site immediately organize personnel to determine the causes of pollution, determine the extent and scope of pollution.

(2) In the event of secondary pollution of soil caused by accident in transportation vehicles, the pollution area shall be used to deepen the method of clearing and digging to completely prevent secondary pollution.

(4) If the pollution level is heavy, it should promptly inform the general headquarters of project emergency rescue and mobilize the relevant resources from the headquarters to prevent the pollution from further aggravating and report to the relevant government department in charge.

3. Emergency Plan against Major Pollution Accidents in Transit

(1) In case of major pollution accidents (for example, the rear baffles are opened, so polluted soils are thrown to the ground on a large scale, and the drivers discard the polluted soils at will) in transit, an emergency plan should be initiated immediately after the pollution accident reports are received. The emergency response commanding center should instantly assign personnel and equipment to the accident sites.

(2) Special personnel should be assigned to guide the transport trucks, and other public vehicles are prohibited from rolling the leaked polluted soils.

(3) Emergency personnel and equipment should be assigned to clean up the sites, collect the remaining soils, and transport the soils to the remediation site for remediation.

(4) If drivers discard polluted soils at will, an emergency plan should be initiated to take appropriate measures, for example, find the trucks concerned and places that soils were discarded, assign personnel and equipment to collect the discarded polluted soils, and transport the collected polluted soils to the remediation site for remediation. In case of failure to transport the discarded polluted soils, appropriate measures should be taken to prevent secondary pollution, and the accident should be reported to the authorities concerned to investigate who are to blame for the accident.

4. Emergency Plan against Major Traffic Accidents in Transit

In case of major traffic accidents, it is necessary to initiate both the emergency plan against major traffic accidents and the emergency plan against major pollution accidents. Emergency personnel should reach the accident sites instantly, check the accident sites, rescue the wounded personnel, and report the accidents to the police. In addition, they should set up warning signs, investigate the leakage of polluted soils, and formulate an emergency pollution treatment program.

After the traffic accidents are handled completely, they should rent some trucks to transport the polluted soils the remediation site for remediation.

The required protective devices mainly include light-duty protective work clothes, acid/alkali-resistant shoes and gloves, safety goggles, gas mask, and safety helmets. The construction managers should strengthen the management of use of articles for labor protection, check the quality of such articles, and make necessary records. All personnel who participate in soil remediation must wear appropriate protective articles and take appropriate measures for personal safety.

Shenyang Lvheng Environment Consulting Co. Ltd 127 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Figure 36Figure 4.2-6 Articles for Personal Safety Protection Protection of respiratory tract: Normally, dust masks should be used. If there is some volatilized organic gas in the operation environment and the toxicant concentration is within a specific range, filtering respirators can be used. In case of emergency or if the toxicity and concentration of toxicants are very high, isolation respirators should be used.

Eye protection: Safety masks should be used.

Body protection: Depending on the toxicity and possible contact concentration, the construction personnel may use anti-poison clothes, rubber work clothes, work clothes proof against poison permeation, and ordinary operation protection clothes.

Hand protection: The construction personnel should use anti-chemical gloves and rubber gloves.

If construction personnel suffer chemical injury, they should receive the following treatment:

Dermal contact: Take off the polluted clothes, and wash the skin thoroughly by using soapy water and clean water.

Eye contact: Lift up the eyelid, wash the eyelid thoroughly by using flowing clean water or normal saline, and have the injured personnel hospitalized.

Inhalation: Leave the site quickly, go to a fresh-air place, and keep the respiratory tract unobstructed. If they have the symptom of expiratory dyspnea, they should receive oxygen therapy. If they have the symptom of respiratory arrest, they should receive artificial respiration immediately, and be hospitalized urgently.

Oral intake: The injured personnel should drink enough warm water, use the emetic method, and be hospitalized.

2. Other Safety Protection Measures

Safety measures should be taken within the construction operation areas. The whole construction range should be marked by warning signs, and anti-landslide measures should be taken if the excavation depth is very great. To prevent engineering accidents (for example, personal

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site damage or equipment damage due to local collapse of soils), sufficient technical personnel should be assigned to the excavation site, to guide the running route and excavation operations. During soil excavation, the excavation equipment should not impact the temporary supporting facilities for the constructed areas. The bottom of foundation pit should not be over-excavated, soils should not be piled or loaded around the foundation pit, and the ground overload should be not more than 10 kPa.

4.3 Implementation Scheme of Ex-situ Remediation Engineering

4.2.1 Process of the Implementation Scheme

The PAH/DDT/TPH-polluted soils, organically polluted soils and compositely polluted soils should all be subjected to ex-suit remediation. The commonly used ex-suit remediation methods include chemical oxidation and thermal desorption. Figures 4.3-1 and 4.3-2 show the technologies processes of chemical oxidation and thermal desorption, as well as their pollution discharge nodes.

Figure 37Figure 4.3-1 Technological Process of Chemical Oxidation and Pollution Discharge Nodes

Figure 38Figure 4.3-2 Technological Process of Thermal Desorption and Pollution Discharge Nodes (1) Chemical Oxidation

① working principle

Project chemical oxidation of ectopic oxidation of chemical agents used for the KS and N agents.

The main component of the KS chemical reagent is sodium persulfate. The main component of the activator N reagent is lime, which is the advanced oxidation technology specifically aimed at soil and groundwater pollution control. Pharmacy as a solid for the treatment of pollution sources or pollution plume benzene, chlorinated hydrocarbons, phenols, pesticides and other organic pollutants.

The selected BH agents, KS agents and N agents are currently widely used in soil remediation and groundwater remediation. The main components are free of heavy metals and toxic and hazardous materials, and do not cause new heavy metals and toxic and harmful pollutants in soil and groundwater. Therefore, The items selected for the site site repair meet the requirements.

② process

Shenyang Lvheng Environment Consulting Co. Ltd 129 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Chemical oxidation of soils comprises three steps: crushing, piling & maintenance, and sample test.

 Crushing: Polluted soils are fed to a crushing machine through forklifts, and then are crushed and screened (dry separation). Large stones are screened out. Fine soils are fed to an agitator. Every time, 10 m3 fine soils, a chemical agent and a little water are added to the agitator for agitation. The agent should be distributed evenly, to ensure good remediation effect.  Piling & maintenance: The pretreated soils are transported to the temporary soil storage zone for piling & maintenance. The maintenance time of organically polluted soils is eight to fifteen days. Depending on the degree of pollution, the soils to be maintained are respectively piled into long soil stacks. After the soil moisture content is adjusted to 30% or so through water replenishing, the soils should be covered by plastic films for maintenance. In the process of soil maintenance, soil moisture content should be measured by sample regularly, and the soils should be replenished water promptlypromptly as appropriate, to keep the water moisture content of 30% or so.

 Sampling test: Upon expiry of maintenance time, the maintained soils should be sampled for self-test at a frequency of 1 sample per 500 m3 soils. During the sampling process, sampling points should be set up strictly pursuant to the sampling specifications. Soil samples should be acquired from the specified depth, and the acquired soil samples should be sent to a qualified third-party test institution for analysis and test. If the pollutant concentration in the soils is below the target values of soil remediation, the soil remediation is accepted. Otherwise, the soils should be subjected to chemical oxidation again, until the self-test results are accepted.

(2) Thermal Desorption

① working principle

According to the different heating methods, thermal desorption technology can be divided into direct thermal desorption technology and indirect thermal desorption technology two types. The main difference between the two is the desorption system and exhaust system. For direct thermal desorption, the contaminated soil enters the thermal kiln and comes into direct contact with the flame or hot flue gas generated by the burner of the thermal kiln and is uniformly heated above the temperature at which the target contaminant is vaporized to separate the contaminants from the soil purpose. Direct thermal desorption has high processing capacity (20 to 160 t / h) due to direct contact between soil and flame, but also produces a large amount of tail gas treatment costs. Indirect thermal desorption of indirect contact with the soil heat medium, the desorption of gas through the

The main technical parameters

● pre-treatment: the particle size of the soil <50mm, moisture content <20% (mass moisture content).

● Thermal desorption scale: 6~10t/h (single 5t/h, 3 sets, total 15t/h)

● feeding system: automatic feeding device, feed inlet should be prepared to maintain air tightness of the device to ensure the stability of the furnace incineration; feed should prevent waste clogging, to keep the feed clear; feed system should Under negative pressure to prevent the escape of harmful gases

● heating temperature and residence time: 400 ° C, 30min or 500 ° C, 20min

② process

Thermal desorption of soils comprises three steps: crushing, indirect thermal desorption, and test and acceptance of remediated soils.

 Crushing: Polluted soils are fed to a crushing machine through forklifts, and then are crushed and screened. Large stones are screened out. Fine soils are fed into the thermal desorption equipment through a conveyer belt.

 indirect thermal desorption

1) material after pretreatment, will meet material disposal conditions of closed to the feed system, and then into the indirect heat of combustion appendage, heated for the material, the organic pollutants in the soil evaporation gasification, and soil effective separation. Use natural gas as fuel.

2) after the contaminated soil in the thermal desorption device is fully heated and defouled, the soil is treated after cooling and spraying.

3) thermal release of the heated evaporation occurring in the appendage of mixed gas containing dust, after circulating water spray into the mist cans, gas purification tank (activated carbon), and then into the combustion chamber consists of 15 m high vent discharge.

4) after spraying, the liquid will enter the circulating water tank after buffering the water tank, and will be discharged regularly through air cooling and recycling or drainage waste water collection box and discharged into the comprehensive sewage treatment station of eastern medicine. Then through Shenyang Lvheng Environment Consulting Co. Ltd 131 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

 Test and acceptance of remediated soils

For the soil with thermal desorption, a sample is collected at a frequency of 500m3 for self-testing.

Sampling points are arranged in strict accordance with the sampling specifications, and samples are collected at the predetermined depth using tools. In view of the soil testing conditions of the construction unit, the soil samples collected shall be analyzed and tested by the construction party. If the pollutant content in the soil is lower than the target value of repair, the restoration is qualified; if the target value is higher than the target value of repair, the thermal desorption is disposed.

After the chemical oxidation restoration, the standard soil was recycled in the new factory of dongyao. After thermal desorption restoration, the soil can be filled back or discharged as residual soil.

4.3.2 Primary Pollution Sources and Environmental Impact Analysis

4.3.2.1 Waste Gas

1. Volatile Organic Pollution Gas

In the process of ex-suit remediation, the volatile organic pollution gas is mainly generated during chemical oxidation and by the untreated soil stacks in the new factory.

(1) Chemical Oxidation Process of Soils

In the process of chemical oxidation of soils, a small quantity of VOCs will be volatilized. The soils under chemical oxidation should be covered by plastic films, to reduce the fugitive emission of

VOCs. In the process of chemical oxidation, soils should be replenished with water. In the process of water replenishing, the plastic films need to be pulled open, so a small quantity of VOCs will be volatilized.

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site concentration mother liquor and non-biochemical waste water generated in the incineration process.

The hazardous waste activated carbon produced by this project can be burned. And the amount of hazardous waste produced by the project is about 36t. The capacity of the incinerator can meet the needs of the project.

Through the above analysis, all kinds of solid waste generated in the soil restoration process will not affect the surrounding environment after proper treatment.

4.3.2.5 groundwater

Engineering contaminated soil chemical oxidation (7000 m2) repair workshop, hot stripping repair area (including thermal stripping process of untreated soil staging area, such as pretreatment, disposal areas, a total of about 11000 m2) has taken strict anti-corrosion, seepage control measures on the ground, to avoid the project soil restoration, especially pollution during the staging of groundwater pollution caused by the site. It is required that the anti-seepage performance of the anti-seepage layer should be no lower than the anti-seepage performance of 1.0×10-10cm/s. In this project, cement base permeable crystalline water-repellent was added into the concrete, with a structural thickness of 310mm.

After the operation of the project, a small amount of waste water will be generated. Relying on the existing drainage pipe network in the Northeast Pharmaceutical Plant plant, it will not have a direct impact on the groundwater. The surface of the contaminated soil deposit area is covered with plastic film tarpaulin. After the ground is strictly impervious to infiltration, the pollutants in the soil will not contaminate the soil through rainfall infiltration into the ground. In addition, after the initial rainwater collection in the eastern medicine factory area on which the project is based, it will be discharged into the sewage treatment station without the formation of ground runoff, which will pollute the soil and groundwater. Therefore, the construction of this project will not have a significant impact on the groundwater environment.

4.3.2.6 Environmental Impact Prediction for Decommissioning Period

Considering actual conditions, the soil remediation in the new factory is estimated to take 240 days. After soil remediation is complete, the remediation engineering will be dismantled. The remediated soils for the construction project mainly contain seven heavy metals (including arsenic, copper, zinc, nickel, lead, chrome, and mercury), five PAHs (including tetraphene, benzoapyrene, benzo[b]fluoranthene, dibenz[a,h]anthracene, and indeno(1,2,3-cd)pyrene), two types of POPs Shenyang Lvheng Environment Consulting Co. Ltd 138 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

(including DDT, DDD, DDE, and -hexachlorocyclohexane), aniline, two types of VOCs (including benzene and chloroform), and TPH(

In the decommissioning period, the equipment concerned will be dismantled and be sold.

4.3.3 Pollution Control Measures 4.3.3.1 Measures for Air Pollution Control For Ex-situ Remediation, exhaust gas is generated while soils are fed and outputted, and are subjected to chemical oxidation and thermal desorption. The following measures should be taken to control air pollution.

1. Exhaust gas generated while soils are fed, crushed, agitated, and outputted

The soil chemical oxidation treatment process is located in the closed workshop, spraying water and dust. The amount of dust produced in the process of soil thermal desorption is small, and the feeding port is located in a closed greenhouse. The soil is transported by a closed belt. The thermal desorption material is located in the closed color steel house, and a spray device is set at the exit.

After the above measures are taken, dust is discharged out of the workshop through the natural ventilation of the workshop.

2. Exhaust gas generated in the process of chemical oxidation

The soils under chemical oxidation are covered by plastic films, to reduce the fugitive emission of VOCs and SVOCs.

3. Exhaust gas generated by the untreated soil stacks

Cover the untreated soil stacks with dust net and plastic rain-proof film, compacted and regularly spray inhibitors to reduce the discharges of VOCs. When the untreated soil is taken out of the soil, it needs to partially open the covered plastic film and cover and compacted the soil in a timely manner.

4. Exhaust gas generated in the process of thermal desorption

The waste gas generated in the process of soil thermal desorption is discharged at an altitude of

15m high exhaust air tube after reaching the standard through spraying ， mist removal tank ， gas

4.3.3.2 Measures for Wastewater Pollution Control

The waste water produced in the process of soil chemical oxidation and thermal desorption is mainly discharge from spray tanks and domestic sewage of employees. The above wastewater is discharged into the new comprehensive sewage treatment station of the northeast pharmaceutical factory, and then discharged into the west shenyang sewage treatment plant through the municipal sewage pipe network after reaching the standard.

4.3.3.3 Measures for Noise Pollution Control

Noise generated in the process of soil chemical oxidation and thermal desorption mainly comes from thermal desorption equipment, screening device and forklift truck. Specific prevention and control measures are as follows:

1. When selecting equipment, thermal desorption equipment, screening device and forklift truck, low-noise equipment shall be preferred to reduce noise from the source strength;

2. Reasonable layout is of great importance. High-noise noise sources should stay away from the factory boundaries, thus reducing noises through range attenuation. In addition, vibration damping measures should be taken for equipment foundations.

4.3.3.4 Measures for Solid Waste Pollution Control

The solid waste produced in the process of soil remediation is mainly the waste activated carbon produced by the adsorption of activated carbon and the domestic waste of employees. Among them, the waste activated carbon belongs to the hazardous waste (HW49 other waste), which is temporarily stored in the hazardous waste room of the new pharmaceutical factory in northeast China and incinerated by the hazardous waste incinerator of eastern medicine. Due to the pollutants concentration distribution in the soil, soil management process, activated carbon usage may be below or above forecast, should be based on monthly, hot stripping exhaust test result judgment, activated carbon adsorption effect, that the test results is high, should be timely replacement of activated carbon. Household waste shall be uniformly cleared and disposed of by the sanitation department.

5. Social Environmental Impact Assessment and Analysis 5.1 Social environmental impact identification Based on the engineering analysis, analyze the possible impact of the project on the social environmental impact factors during the construction period and operation period, and establish the main identification matrix of environmental impact factors, as shown in Table 5.1-1. Table 57Table 5.1-1 Social Environment Impact Identification Project activity elements Soil excavation Soil remediation Soil transport Land use -1SP +3LP social environment traffic -1SP -1SP Humanities and Public health -1SP -1SP Ecology city traffic -1SP Remarks: Impact degree: 1 - slight; 2 - general; 3 - significant Impact period: s-short-term; L-long-term; Range of influence: P-local; W-large range; Influencing nature: + - favorable; - negative; 5.2 Social environmental impact assessment factor The project does not involve land acquisition, house demolition and resettlement. According to Table 5.1-1, the social environmental impact assessment factors for this project are land use, transportation and public health. 5.3 Social Environmental Impact Analysis 5.3.1 Impact of the Project on Traffic The impact of the project on traffic is mainly the stage of soil transport. According to the project engineering analysis, after the excavation of the project, the contaminated soil is transported by on-site mechanized loading and dump trucks, and transported by Heavy Industry North Street, Shenda Road, Honghu Street, Development Road, Xihe Qibei Street and Shenxi Liudong Road. To Dongying New Factory, the transportation distance is 23km. Therefore, the soil transport phase will have a certain impact on traffic in Shenyang. However, due to the short construction period of this project, the impact on traffic is short-term. 5.3.2 Impact of the Project on Land Use Heavy metals, SVOCs, DDT, etc. in the original soil of the project all exceeded the standards. According to the overall land use plan of the government, the site will be redeveloped and used as a residential land (second-class residence) in the future, and on February 12, 2017. The land was acquired by China Resources Land (Shenyang) Co., Ltd. If it is not repaired, it will Shenyang Lvheng Environment Consulting Co. Ltd 142 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site affect future land use. 5.3.3 Impact of the Project on Public Health The impact of the project on public health is mainly reflected in the process of soil excavation and soil transport. The dust and noise generated during soil excavation will have an impact on public health; the noise generated during the soil transportation process will affect the residents' public health. 1. Effect of construction dust on public health Construction dust is mainly composed of particles with a large particle size. If dust particles enter the lower respiratory tract at 10 μm, they will accumulate in the alveoli when they are less than 2.5 μm, causing a series of diseases, which can lead to lung failure in severe cases. dead. By consulting the relevant literature, in some factories or construction sites, due to construction personnel activities or the operation of machinery, a large amount of dust is suspended in the control, which will not only increase the dust concentration, but also reduce the air quality. Because the dust contains a lot of heavy metals such as oxysulfuron, and the reaction is likely to produce poison, it will not only affect the growth of surrounding plants, but also affect people's health. After all, dust particles containing heavy metals will move with the air. Once micro-particles enter the respiratory system and accumulate in the alveoli, a series of diseases will result. Coupled with the large amount of bacteria and viruses in the dust, dust will become a medium for bacteria and viruses to speed up the spread, seriously affecting the health of residents. According to the engineering analysis, dust will be generated during the construction process of this project, and the estimated range of impact is about 200m. According to the site investigation, Wankelun Runyuan (4100 people), Xingong New Village (4000 people) and Lanting Xinju (4100 people) are involved in this area. ), Tiexi District government office staff (1000 people) about 12,000 people, 4560 households. Therefore, the dust generated during the construction of the project will have a significant impact on residents and office workers in the above communities. However, due to the short construction period of the project and the corresponding measures taken, the impact on the health of residents will be short-lived. After construction, the impact disappeared.

Shenyang Lvheng Environment Consulting Co. Ltd 143 #109-5 Level 17, Block H, Quanyun road, Hunnan District, Shenyang City

2. Impact of construction and vehicle transportation noise on residents' health (1) Combining with project engineering analysis, the noise generated during the construction process mainly comes from the operation of construction equipment. The estimated noise value is between 80 and 90 dB. Related data shows that: “40 dB(A) continuous noise affects 10% of people’s sleep, 70 dB(A) affects 50%; sudden noise is 40 dB(A), 10% of people can wake up, and 60 dB can awaken 70% of people.” This shows that the construction process will cause residents to sleep influences; (2) Affects conversation and communication. Usually the conversation is no louder than 70 dB, and the loudness is up to 85 dB. When the noise level is close to the conversational level, normal conversation will be disturbed. When the noise level is more than 10 dB higher than the speech level, the speech is completely masked. Normally, 65 dB noise will interfere with normal conversations. You must raise your voice or close to the distance to talk. If the noise level exceeds 90 dB, shouting is also not clear. It can be seen that the noise generated during the construction process will affect the normal conversation and communication of the people; (3) Effects on the nervous system. Noise acts on the nervous system for a long time and can cause dizziness, headaches, and tinnitus. It interferes with the concentration of mental work and reduces the ability to work. Under the action of noise, the human brain wave changes, and the time value of vestibular and motor nerves also occurs. Variety. After the noise acts on the nervous system, it also affects other systems, such as the role of the digestive system, which can cause loss of appetite; (4) Affect work. Distract people's attention, make people easily tired, unresponsive, affect work efficiency, increase work error rate. However, due to the short construction period of the project, after taking corresponding measures, the impact on the residents' health is short-lived. After construction, the impact disappeared. 5.3.4 Prevention measures 1. Traffic prevention measures Taking into account the impact of project construction on traffic, the project has formulated the following plans: The construction unit will enhance the traffic safety education for the

Traffic technical specifications signs. 2. Noise prevention measures ① During the implementation period of the project, the noise emission shall not exceed the limit value of the “Emission Standard for Environmental Noise of Construction Site Boundary” (GB 12523-2011), that is, 70dB in daytime and 55dB at night. ②Try to use low-noise or construction machines equipped with noise elimination and noise reduction equipment. ③ For strong noise equipment, use noise enclosures to close and block noises. ④Strengthen the promotion of environmental awareness, adopt effective measures to control artificial construction noise, strictly manage and minimize noise disturbance. ⑤The construction personnel who operate the high-noise equipment at close range should wear earplugs, and should arrange rotation work or shorten their working time to reduce the harm caused by noise to human ears. ⑥ Reasonably arrange the construction time, and it is forbidden to work from 22:00 pm to 6:00 the next day. If night construction is required, the relevant departments must go through the relevant approval procedures in advance and obtain consent from the surrounding residents before the construction can be carried out.

3. dust prevention measures (1) Set up a continuous enclosure of not less than 2.5m around the restoration site and use a mobile spray dust collector to spray dust at the construction site; (2) Use an integrated machine for soil remediation to ensure that the contaminated soil is stirred and broken in a completely enclosed environment, and that the surface of contaminated soil in the soil temporary storage area is covered with rain-proof cloth or membrane, and bare stacking is prohibited. Also, the rain-proof cloth should be fixed so as not to be blown by the

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site participation in the environmental impact assessment process can enhance the effectiveness of the environmental impact assessment, raise public awareness of the environment, improve the environmental impact assessment system, and protect the quality of the environment, which is conducive to maximizing the overall and long-term benefits of the project. 6.1.2 Principles of Public Participation (1) Impartiality, Fairness and Openness In the establishment of the system for public participation in evaluation, the principles of impartiality, fairness and openness must be followed. The symbolic power of impartiality restricts the mechanism of participation, making government intervention in correcting market failures at the same time to avoid and overcome the government failure, and the choice (sampling) of the subjects consulted or participating in the deliberations should be representative so as to ensure that the public participating in the deliberations come from all walks of life and represent a social section. Fairness symbolizes the participation of the interests of the coordination mechanism. Equitable distribution and coordination of limited natural resources and social resources were also one of the basic goals of urban planning. Public participation must be based on the coordination of the interests of all societies to find out the public interest that truly reflects the public will. This public interest is the policy basis for the government to formulate and implement the project and is one of the effective ways to gain public support for the planning. Openness symbolizes that the information interaction mechanism of public participation must protects the public's right to information on the project, the right to participate and supervision, to improve the use of administrative power and administrative work transparency, and maintain social justice to ensure that the public have a more comprehensive cognition and more accurate judgment during their participation. (2) Specificity and Operability The formulation of public participation system must have strong specificity and operability. Public participation is a highly social work. It is necessary to explain to the participants that the project may exert positive and negative impacts on society, economy, and environment, especially on resource allocation and public interests so that the public can understand the overall situation of the project as soon as possible to make a correct judgment. At the same time,

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site the results of public consultation should be dealt with quantitative statistics to render the evaluation more convincing. The evaluation results should be easy to operate and help with the decision-making process. We must also give full consideration to the difference in cognitive ability and educational backgrounds of people in different social strata. Evaluation indicators or factor descriptions that require public consultation should be simple, clear, and understandable, and should not be too specialized. (3) Dynamic Participation The formulation of public participation evaluation system should follow the principle of dynamic participation. The types of projects, operation phases and affected strata (public composition) in each project are undergoing changes and adjustments. Therefore, the contents of the public consultation or indicators and emphasis are different. The selection of the factors of evaluation index and the corresponding weights should be dynamically adjusted according to the project and its process. 6.2 Scopes and Subjects of Public Participation The investigation of public participation in this study concerned the evaluation scope and the main affected areas of the remediation project, focusing on the opinions of social organizations and individuals in the areas. The survey included local people, staff from enterprises and public institutions, and staff from government agencies affected by the project. The age groups covered young and middle-aged people as well as the elderly. 6.3 Ways and Contents of Public Participation 1、 a message publicity ⑴ on-site publicity Northeastern Pharmaceutical Group Co., Ltd. staff in January 21, 2018 to January 25, respectively, Vanke Long Run Park, Heavy Industries Village, Shenyang City, No. 36 Middle School on-site publicity, publicity includes: project overview, to be taken by the environmental protection Measures, contact information (including construction units, evaluation units) mailing address, contact telephone number, contact person and e-mail address; public notice also shows the scope of time for public comment.

7. Environmental Investment and Environmental Benefits Analysis 7.1 Overview Environmental impact economic benefit and loss analysis is mainly to evaluate the cost of environmental loss after the implementation of the construction project and the social, economic and environmental benefits brought by various environmental protection measures. The cost of environmental loss mainly includes the loss value of the impact on the surrounding ecological environment and human health due to pollutant discharge and pollution accidents, the lost value of resources and energy, and the operation, maintenance and management expenses put into operation for maintaining various environmental protection facilities. Environmental economic benefits mainly include the value of recovery and comprehensive utilization of resources and energy after the implementation of various environmental protection measures, and the social and environmental benefits brought by mitigation of environmental pollution. Environmental economic losses and benefits are generally indirect, difficult to calculate in the form of currency, and also difficult to calculate accurately and with greater uncertainty. Due to the absence of uniform standards, mature methods or related norms for environmental and economic benefit and loss analysis, the task was somewhat difficult. The evaluation in this study merely described and analyzed some aspects of the above content to a limited extent.

7.2 Environmental protection investment estimates This project was a remediation project of contaminated soil. In order to solve the secondary pollution in the process of soil remediation, it was estimated that the investment in environmental protection would be 2.03 million RMB, accounting for 2.31% of the total investment of 88.041 million RMB.

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site utilization of the land in the later period, thus wasting precious urban land resources, and was extremely inharmonious with the surrounding living environment, seriously affecting the integrated image of Tiexi District. According to the latest plan of Tiexi District, soil remediation of this plot will play an active role in promoting the development and utilization of land and the overall image of the region, thus promoting the development of the city. Contaminated site soil remediation will reduce the pollutants in the soil harming the surrounding residents, and reduce the chance that the surrounding residents are affected by contaminants in the soil and the need for treatment of diseases, thereby reducing health care costs.

7.4 Environmental Benefit Analysis If the contaminated site of heavy metals and organic compounds formed after the relocation of the north plant area of the original Northeast Pharmacy plant is left for a long time without treatment and remediation, the pollutants in the soil will enter the atmosphere and harm the surrounding residents; on the other hand, rainwater infiltrates into the soil, pollutants continue to enter the lower soil and groundwater, pollutants continue to migrate and spread, not only the soil pollution continues to increase, but also pollute the groundwater, environmental risks continue to increase. If not timely rectified, over time, it will bind to increase the continuous accumulation of environmental pollution in the region. The implementation of soil remediation project can control the migration and diffusion of pollutants and reduce the further pollution of the atmosphere, soil and groundwater. In conclusion, the soil remediation project on the plot will improve the living environment for residents in the area, improve the environmental quality of the surrounding atmosphere, soil and groundwater, optimize the investment environment and promote the sustainable development of society and economy. The environmental benefits and social benefits brought by the remediation of polluted soil are very significant and have a positive effect on improving the local environmental quality.

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site process of soil excavation. During the excavation and transportation of contaminated soil in the site, the size of monitoring area, the characteristics of the spatial distribution of pollutants and meteorological factors will be taken into consideration. Both inside and outside the site will be set with air sampling points. ① Determination of Monitoring Sites During the process of soil excavation, the air pollution belongs to unorganized discharge. According to the Technical Guidelines for Site Environmental Monitoring (HJ25.2-2014), the monitoring sites should be set at the boundary of the site, and the monitoring sites should be arranged in appropriate proximity to the environmental sensitive sites near the field area, and the eastern border near the environmentally sensitive point. Before the start of the remediation process, during the remediation process and after the end of the remediation project, employ a third-party testing organization to conduct on-site sampling and laboratory analysis. Determine the impact of unorganized exhaust generated during construction on the surrounding environment. ② Monitoring Frequency The contaminated soil treatment project will be sampled once before the start of construction as a background value; a sampling will be taken once a week during the period of soil remediation; and once the soil treatment project was completed, it will be monitored once again. Sampling of unorganized emissions requires a random sampling of one hour continuous sampling. ③ Monitoring Indicators and Emission Standards The pollutants in the site's atmospheric environment are mainly total suspended particulates (TSP). The atmospheric environmental quality standards are implemented according to the Integrated Emission Standard of Air Pollutants and Ambient Air Quality Standard, and the emissions during the construction process are unorganized emissions. Therefore, the emission standards will be implemented according to the unorganized emission monitoring concentration limits. 2. Noise Monitoring During the construction process, monitoring should be carried out in days without rain and

Construction Dust The main problems of air pollution in this project are the dust generated from soil dredging, remediating and transiting, as well as road dust generated from the construction motor vehicles and transport vehicles. According to the field survey, the site boundary is 20 m and 10 m away from the Wanke Spring Dew Mansion Residential Community and the Shenyang Tiexi Government Office, respectively. Due to the short distance, the dust generated during the construction process will affect the above-mentioned regional environment. The EIA recommends that a continuous enclosure of not less than 2.5 m height be provided around the site of remediation before the project starts, and to sprinkle water throughout the remediation process of the soil. All types of soil temporary storage areas in the temporary storage area should be covered, and soil remediation area (curing stabilization) should be set with closed membrane structured shed or enclosed treatment by an integrated machine, and the entire remediation project should be carried out in an enclosed environment; in the process of soil excavation, loading should be slowed and falling height should be reduced to reduce dust. After taking the above measures, the concentration of TSP in the air can be greatly reduced, the dust pollution in the construction site can be effectively alleviated, and the impact will disappear immediately after construction. 2. Exhaust of Construction Machinery and Equipment and Transport Vehicles Exhaust of machinery and equipment exhaust gas and transport vehicle tail gas will also exert some influence on the construction site, but the impact of construction vehicles is much smaller than that of traffic vehicles. As the exhaust gas of construction equipment and transport

Global environmental fund “China Contaminated Site Management Project” Liaoning demonstration project Environmental and Social Impact Assessment Report for Remeidation of the Northeast Pharmaceutical Plant contaminated site vehicles used will be discharged intermittently, and the impact will disappear immediately after construction, so it will have little effect on the ambient air quality. 9.4.1.2 Water Environment Impact Analysis The waste water produced during the process of soil excavation is mainly from flushing wheels of transport vehicles and domestic sewage generated by construction workers. As this project will not be conducted in the rainy season, foundation pit water will not be involved. According to engineering analysis, the flushing water for wheels of transport vehicles will be recycled after being treated in sedimentation tanks and will not be discharged outside; the domestic sewage produced by construction workers will be treated to standard by septic tanks in the south plant area of Northeast Pharma, and then discharged into the Xiannu River Sewage Treatment Plant through the municipal sewer network. 9.4.1.3 Noise Environment Impact Analysis The noise sources of this project are mainly the noise generated by mechanical work during site preparation, soil dredging and soil remediation. Mechanical noise is mainly generated by excavators, bulldozers, integrated mixers (curing stabilization), etc., mostly point sources. The noise generated by these machines is usually at the level of 75-85dB (A). In addition, there are some sporadic instantaneous noises during construction work, such as beating noise and percussive noise. The noise of construction vehicles is traffic noise. The project will construct a continuous and enclosed enclosure with height not less than 2.5m around the site for remediation, which will have good sound insulation effect for excavation noise. In addition, low-noise equipment will be selected to be used and measures such as enclosure and shielding of high-noise equipment will also be used. Noise can be reduced by about 20dB (A) after taking measures. 9.4.1.4 Environmental impact analysis of solid waste The solid wastes generated in this project were mainly polluted soil excavated and a small amount of domestic garbage generated by staff. According to the Remediation Plan of Northeast Pharmacy POPs Field (Production Area of North Plant Area on North Second Road, Northeast Pharmaceutical Group Co., Ltd.), the volume of soil to be excavated in the project is 70171m3, and some of the soil is transported to the new Northeast Pharmarcy plant for remediation; some
