1. Overview and Compilation Basis 1.1 Overview and Objectives 1 To tackle environment pollution in rural areas caused by the rapid development of large- scale farms in China, Chinese government initiated the Chinese Rural Energy Ecology Building Project (Phase Two) which has received USD 130.5 million loans and donations from Asian Development Bank (ADB), Global Environment Fund (GEF), Clean Energy Financing Partnership Facility (CEFPF), etc.

2 The project supports 66 biogas subprojects in Heilongjiang Province, Henan Province, Shandong Province and Jiangxi Province. Given the workload and cost, environment monitoring is only carried out on 18 projects. Please see Table 1-1 below for more information about enterprises under environment monitoring. Environment monitoring includes ambient air, surface water, underground water and noise environment. According to ADB's opinion on the 2016 Environmental Monitoring Report, monitoring report in 2017 has been adjusted and supplemented in the following three aspects:(1) The odor concentration monitoring in some biogas project has been added;(2) Through on-site investigation, groundwater and surface water sampling points are re-selected and adjusted, so the new monitoring data surface water and groundwater has been added and analyzed. The original biogas slurry sample is part of the biogas slurry treatment process, and the results can reflect the fermentation effect, not as a basis for judging the environmental impact of enterprises on the surrounding water environment; (3) Environmental director for each enterprise has been added.

3 Harbin Running Environmental Technology Limited Liability Company has undertaken the environment monitoring of one project in Heilongjiang Province, and have completed once in June 2019.

5.5 Environmental impact analysis

101 In order to meet market needs and environmental protection requirements, Jiangxi Bank's 33 sub-projects applied for ADB loans to lease barren hills and wasteland to build biogas projects and wastewater treatment systems, including: anaerobic fermentation tanks, gas storage membranes, deployment tanks, feed tanks, and Ancillary facilities; generators and ancillary facilities; boilers and ancillary facilities; gas pipeline networks for gas cookers and ancillary facilities; sewage treatment systems, including conditioning tanks, two-stage a / o tanks, contact oxidation tanks, MBR tanks, Sedimentation ponds, sludge ponds, biochemical ponds, etc. Ecological agriculture construction content: mainly to construct surrounding irrigation farms, vegetable plantations, seedling bases and other irrigation pipes, facilities, liquid storage ponds, etc.

102 Jiangxi ADB's 33 sub-projects adopt ecological farming methods, implement intensive and large-scale feeding, not only supporting facilities such as biogas ponds, orchards, fish ponds, etc., develop ecological agriculture of "pigs, marsh, fruits and vegetables", and strive to achieve ecological zero emissions The reasonable pollution prevention and control measures adopted have treated various pollutants produced during the production process and reached the standard discharge, which will minimize the adverse effects on the external environment.

103 Surface water environmental impact analysis

The production wastewater of the project is mainly flushing manure, domestic wastewater, production wastewater, and wastewater discharged from sewage treatment systems. The wastewater from livestock and poultry farms is a high-concentration organic wastewater with a high concentration of SS, COD, and BOD5. High specific gravity of urine and feces, large content of NH3 -n and phosphorus, perishable, single emission and other characteristics. If it is discharged arbitrarily, it will have serious environmental impacts on the local environment.

The biogas project constructed by the project belongs to the environmental treatment project. Anaerobic and aerobic treatment is performed on the flushing manure, domestic sewage, and production wastewater produced by the pig farm. After the anaerobic fermentation of the project biogas project, it is converted into biogas slurry as agricultural fertilizer. It is used for the cultivation of ecological agriculture. Or it can be discharged after the anaerobic-aerobic secondary treatment. It is concluded that the wastewater generated by the project will not affect the surrounding surface water.

104 Impact analysis on groundwater

The sub-project's biogas project does not take groundwater, and it affects groundwater pollution in category I. It is mainly caused by anaerobic fermentation, biogas slurry, and biogas residue storage pollutants infiltration of groundwater. According to the geological survey report of the area, the geology of the area The conditions are better and better, the soil has a strong ability to adsorb pollutants, the soil layer has poor permeability, the wastewater waste has poor mobility, and the comprehensive aeration zone has a strong ability to remove air. According to regional data and site surveys, there is no centralized drinking water source near the project (Including completed in-use, standby, emergency water source areas, water sources under construction and planned), quasi-protected areas and other sensitive targets, without more sensitive areas such as: centralized drinking water source areas (including established in-use, standby water sources , Emergency water sources, water sources under construction and planning) recharge runoff outside the quasi-protected area,

In order to prevent aquaculture wastewater, biogas slurry storage, biogas residues, etc. from contaminating groundwater in the project location, the project requires the implementation agency to take measures to prevent groundwater pollution:

(1) Key polluted areas

The anti-seepage measures are as follows: the fermentation treatment facilities, biogas slurry ponds, and slag storage points are all cement-hardened; the surrounding walls of the fermentation facilities, biogas digesters, and biogas slurry ponds are bricked and cement hardened to prevent

seepage; the entire pond is coated with epoxy resin. Through the above measures, the permeability coefficient of the impervious layer of each unit in the key pollution area can be ≤ 10 -10 cm / s.

(2) General polluted area

Anti-seepage measures: The ground floor of the living area in the factory area and the generator room is clay-plated, and then the upper layer is cemented with 10 cm of cement. Through the above measures, the permeability coefficient of the anti-seepage layer of each unit in the general polluted area ≤ 10 -7 cm / s.

After taking the above measures, it can prevent the groundwater from being polluted by aquaculture wastewater, biogas slurry, and biogas residues.

105 Air Environmental Impact Analysis

The excretion of feces and urine in the farm is very large, which contains a large amount of organic substances, which will rapidly decay and ferment after being excreted, producing hydrogen sulfide, ammonia, amines, thiols, benzoic acid, volatile organic acids, indole, and ethanol malodorous substances such as acetaldehyde, etc., pollute the breeding pens and the surrounding atmospheric environment. In addition to the harmful gases emitted by pens, biogas digesters and compost yards are the main places to emit malodorous gases. The above harmful gases and a large amount of dust and microorganisms generated during production Discharge into the atmosphere and spread over the fence and nearby residential areas, stimulate the respiratory tract of humans and animals, can cause respiratory diseases, affect the health of humans and animals, and the malodorous gas makes people feel unpleasant and affects the work efficiency of the people. Often caused by the decline of livestock and poultry productivity. Various microorganisms discharged from the farm use dust as a carrier and spread with the wind, which can cause the spread of the disease. A large number of mosquitoes and flies in the field are also easy to spread the disease and pollute the environment.

In order to minimize the impact of the foul odor of the biogas project on the ambient air, the project adopts the following measures:

(1) The manure storage yard and grille shall be sealed and sprayed with biochemical deodorant at another place.

(2) Biochemical deodorant can be sprayed at the manure discharge port, slag yard, etc. of the sewage treatment plant.

(3) Timely manure removal measures to suppress or reduce the generation of odor.

(4) Adopt greening measures, plant trees, etc. around the project, strengthen the absorption of exhaust gas, and reduce the impact of foul odors on the atmospheric environment.

After taking the above measures, there are no villagers within 600m of the project. It is known that this project will not affect the villagers.

106 Environmental Impact Analysis of Solid Waste

The farm produces a large amount of manure daily, and there is not enough farmland around to absorb such a large amount of manure. If human factors are not used, the manure is randomly dumped and discharged, which seriously pollutes the surrounding environment and also pollutes itself. Manure treatment is performed in the following two ways. First, the manure is collected manually or mechanically, and the manure is separated dry and wet using a mechanical grille. The manure is stored in a special manure pond for fermenting and composting. The manure directly enters the anaerobic fermentation tank to produce biogas and biogas residue to produce organic fertilizer. Through the above two treatment methods, pathogenic microorganisms and parasite eggs in the manure can be killed, and most of the organic matter is decomposed into humus, and some are decomposed. Into inorganic salts. Through composting or anaerobic treatment, it can avoid the pollution of manure to the environment, and at the same time, it can be used as a renewable resource to turn waste into treasure. The biogas residue and biogas slurry produced are mainly used for the cultivation of ecological agriculture, Manure can be absorbed completely and its impact on the environment is relatively small.

107 Acoustic environmental impact analysis

The noise generated by this project is mainly the noise of the generator, the noise of the pumps and other machinery in the field and the calls of livestock and poultry. The generator room can reduce the spread of noise, and the noise of the farm is about 75-90dB (A). Since the location of the subproject is far from the village, it has little impact on the outside world.

109 Suggestions for the next step

In order to reduce the impact of the project's operation on the surrounding environment, strictly regulate the operation of each process, promote clean production, and formulate strict production safety. It is recommended that the project owner take the following measures:

(1) It is recommended to use high-efficiency anaerobic sludge tank and high-efficiency aerobic biological treatment for biological treatment, which can greatly remove pollutants and suspended solids from wastewater machines, which is the key to ensure that the treated water meets the standard.

(2) Strengthen the sealing measures of the manure storage dry pond to ensure that manure cannot accumulate on the outside of the pig farm, and avoid stacking the manure in the open air, so as to avoid the bad smell affecting the surrounding environment.

(3) It is recommended to use active substances such as microbial preparations, enzyme preparations and plant extracts to reduce pollutant emissions and the generation of malodorous gases.

(4) The house must be well-hygienic, and when pigs are found dead, they must be cleaned and disinfected in a timely manner, the pig carcasses should be properly handled, random disposal is strictly prohibited, and it is strictly prohibited to sell or reuse as feed;

(5) Storage facilities should adopt effective anti-seepage treatment technology to prevent livestock and poultry manure from contaminating groundwater and above-ground water sources and rivers;

(6) Storage facilities should take measures to prevent rain (water) from entering, such as setting a cover.

(7) Further improve the biogas digester, and regularly spray fly, mosquito and deodorant;

(8) Strengthen management and strictly control the abandonment, spreading, running, dripping, dripping and leaking of sewage along the way.

(9) Livestock and poultry breeding feed should adopt reasonable formulas, such as ideal protein system, etc., to improve the absorption efficiency of egg quality and other nutrients, reduce nitrogen emissions and manure production.

(10) Domestic garbage must not be discarded and burned at will to reduce the secondary pollution caused by it. At the same time, the leakage prevention work of the permeate should be done to avoid contaminating the soil and groundwater.

(11) It is recommended to set up a special person to manage sewage treatment facilities, and regularly clean up biogas tanks, and use biogas slurry and biogas residues as fertilizer.

(12) Strengthen the greening work in the factory area. Greening is conducive to the fire prevention and epidemic prevention of pig farms. Planting isolated forest belts without intersecting each other can prevent the spread of epidemic diseases caused by the free movement of humans and animals.

(13) The pollution treatment facilities of this project must be qualified by the local environmental protection department before the implementation agency can be officially put into production.

127 Based on ADB’s Environment Policy (2002) and Environment Assessment Guidelines (2003), the project is classified as environment category B. The IEEs of the six core subprojects were reviewed by ADB, and a summary IEE was prepared and disclosed on ADB project website in December 2008. The summary IEE includes an environmental assessment

and management framework (EAMF) to ensure ADB’s environment requirements met for subsequent subprojects.

128 Due diligence on non-core subprojects. The list of environmental criterion for subproject selection in the EAMF 1 was used as the guidelines for screening and selection throughout non-core subprojects’ preparation. During implementation, the domestic EIAs and approvals of subsequent non-core subprojects have been completed in accordance with PRC’s laws and regulations. ADB approved a total of 24 IEEs (including 1 in Heilongjiang, 2 in Henan, 11 in Jiangxi and 10 in Shandong), respectively, through May 2009 to June 2018.

129 By end 2019, in line with domestic legislations, a total of 46 subprojects (including 1 in Heilongjiang, 9 in Henan, 32 in Jiangxi and 4 in Shandong) passed domestic environment completion acceptance audit by August 2019.

130 MOA, on behalf of the EA, was overall responsible for the implementation of EMP and for effective management of activities specified in the EMP. The four subproject provinces’ PMOs and IAs were responsible for relevant requirements of EMP to be part of design drawings and bidding documents, for the supervision of implementation of mitigation measures during construction and operation, and for coordination of external environment monitoring. Contractors, under the guidance of construction supervision companies, were responsible for the implementation of mitigation measures specified in the EMP during the construction period. The IAs or the operators are responsible for the implementation of mitigation measures during the operation. Within IAs or the operators, their safety and environment protection sections recruited environmental staff; and they are responsible for ensuring implementation of the mitigation measures in the EMP, and coordinating for environment completion acceptance audit and monitoring. Each IA signed the contract with local environment monitoring center as external environment monitoring agency from 2014. Six EMRs, covering period through 2015- 2018, have been submitted and disclosed on ADB project website2.

131 Multiple candidate sites were identified and analyzed for each of the non-core subproject. The following factors were considered for the site selection: i) occupation of less land; ii) safe and sanitary distance to sensitive areas, including residences and residential areas, schools, hospitals, and business and office districts; iii) avoidance of runoff to surface water; iv) avoidance of penetration of leachate to groundwater aquifers; and v) adequate farmland for use of biogas residues to minimize non-point source pollution.

132 Only minor construction and operational impacts were brought by the Project, but these were mitigated to acceptable levels by applying adequate construction and operation management practices. There are no significant/unanticipated adverse effects/risks to the environment.

1 Include the following: i) regulatory restrictions; ii) safe distance from sensitive objects; iii) sensitivity of local environment; iv) carrying capacity of local farmland; and v) environmental commitment of the enterprise. 2 Including four consolidated annual EMRs during 2015-2018, and two EMRs respectively covering January- September 2017 and January-June 2018.

133 Construction period. For all subprojects, the construction of biogas digesters and associated facilities and infrastructure involved removal of vegetation and excavation. The excavated earth was re-used for road building and landscaping, without external disposal. Water and soil retaining weirs were used to avoid soil erosion. Measures such as water spraying and truck covers were adopted so as to suppress the generation of dust. In view of the relatively long distance from sensitive areas and with the use of low-noise machinery, the noise nuisance was minimal. Solid wastes from construction activities were collected by local sanitation bureaus for disposal in landfill sites. The wastewater from construction activities and from construction workers containing no toxic substances was re-used for site spraying and landscaping. The environmental impacts during construction were assessed temporary and localized, and judged to be insignificant, as verified by the monitoring results in the EMRs.

134 Operational period. The major adverse environmental impacts during the operation phase include the following. (i) Odor: The biogas digesters were built adjacent to the livestock and agro-processing operations, and as such the transportation of livestock manure and agro- processing wastes were confined within the farms and plants. Sealed and covered vehicles were used to prevent leakage during transportation. The livestock manure and agro-processing wastes were dumped directly into the biogas digesters; and no storage was necessary. The anaerobic digestion process removed over 90% of the odor. The field application of the biogas residues was scheduled to avoid windy days, such that the odor was not blown too far. (ii) Water Pollution: There is adequate farmland in the subproject areas so the application rate did not exceed the recommended 25 to 50 t/ha/a. In the meantime, the application of biogas slurry and solids in the field took consideration of weather conditions and crop growth status. It was scheduled to avoid the rainstorm season. Moreover, burying instead of spreading also reduced the amount of surface runoff. The application areas are located also as far as possible to water bodies. (iii) Noise: In view of the long distance sensitive areas (e.g., residential areas, schools, hospitals, etc.), the noise impacts on local communities were minimal. However, to mitigate potential noise impact to animals, low-noise equipment was selected, and insulation of power houses was adopted. And (iv) Safety and GHGs Emissions: The mitigation measures included: a) strictly obeying the Guideline on Operation, Maintenance and Safety of Biogas Systems for Livestock and Poultry Farms (NY/T1221-2006) proclaimed by MOA; a) developing and implementing operational safety procedures for biogas facilities; c) providing safety training by biogas system safety experts to operational and management staff; d) installing safety apparatus, including water sealing and constant pressure equipment; e) providing fire prevention and extinguishing facilities; and f) developing and implementing emergency procedures for leakage, fire and explosion, and conduct periodic drills. With the implementation of the above mitigation measures, the impacts/risks were reduced into the minimum, while the operational monitoring results indicate compliance with national applicable standards in the EMRs.

135 Public Consultation and Grievance Redress Mechanism (GRM). The public consultation plan for the core subprojects at appraisal was developed as a template for the subsequent non-core subproject’s public consultation. During implementation, public awareness and public consultation activities regarding environmental aspect for all subprojects

have been conducted. The feedback comments on the measures discussed above and satisfaction to environment provided by affected persons have been collected through interviews, questionnaires and other methods. No environmental complaint or grievance was raised.

136 The project is expected to mainly achieve environmental benefits, reduced water and air pollution, public health improvement, eco-farming expansion, and reduction in greenhouse gas (GHG) emissions. The project uses the solid and liquid waste from these animal and agroprocessing operations, totaling 9.38 million tons per year, as feedstock to produce about 100 million m3 per year of biogas with anaerobic fermentation technologies. Each year, about 14 million m3 of the biogas is transmitted to the local village gas grids, 2 million m3 for heating, and the remaining 84 million m3 is used to generate 120 million kilowatt-hours of electric power. The subprojects also produce 4.3 million tons of liquid organic fertilizers and 0.9 million tons of solid organic fertilizers for eco-farming. The project is estimated to result in an estimated annual GHG reduction of 1.21 million tons of carbon dioxide equivalent. 3 Subprojects that qualify for the Clean Development Mechanism will be assisted to secure carbon emission reduction revenues.

137 Adequate environmental mitigation measures have been adopted and the EMP has been effectively implemented for all the kinds of subprojects during the construction and operation periods to minimize the adverse environmental impacts to an acceptable level during the construction and operation periods. Construction and operation environmental monitoring was carried out, and EMRs were submitted. The environment monitoring results are in compliance with the applicable standards and there are no significant adverse effects to the environment. The actual performance of the environmental protection measures are pursuant to applicable environmental protection regulations and standards. The project has had substantial positive environmental benefits. The project also has a demonstration effect on the other similar renewable biomass energy development projects in four provinces or others in PRC.

3. The climate change benefits from this Project can be estimated by calculating the greenhouse gas (GHG) emissions for with-and- without-biogas-production scenarios. Without biogas production, the major GHG from a livestock farm is methane. According to the IPCC recommendation, the methane。 emission coefficient。 for swine in the temperate zone in Asian regions with annual average temperature higher than 15 C but lower than 25 C is 4 kg per head per year. According to Duan and Wang (2003) , for a swine farm with an average inventory of 6,000 heads and slaughter of 10,000 heads, the methane emission will total 24 t/a or in equivalence of 504 t/a of CO2 under the without-biogas scenario. With the biogas production, the annual biogas production is estimated at 73,000 m3/a. The emission avoided from the coal saving is estimated at 277 t/a of CO2, assuming: i) one cubic meter of biogas will replace 2 kg of coal, ii) the heat value of Chinese anthracite coal is 24,493 TJ/Mt, iii) carbon emission factor is 26.39 tC/TJ, and iv) carbon oxidation ratio is 80%. Thus, the total forgone emission from the with-biogas scenario in comparison to the without-biogas scenario will amount to an equivalence of 781 t/a of CO2.
