Author/Source: Yaha Coal Chemical Industry; Date: 2019-02-22; Clicks: 6. Approval by the Jilin Provincial Department of Ecology and Environment regarding the environmental impact report for the comprehensive utilization project of hydrogen produced by Changchun Dacheng Biotechnology Development Co., Ltd. Changchun Dacheng Biotechnology Development Co., Ltd.: We have received your application for review and the environmental impact report prepared by Jilin Zhongshi Environmental Protection Engineering Development Co., Ltd. After consideration, we hereby grant the following approval: This is a renovation and expansion project, and it will be carried out within the existing factory premises of Changchun Dacheng Biotechnology Development Co., Ltd., located in the Changchun Northeast Biochemical Industrial Park. The main construction tasks include building a new methanol production line with an annual output of 165,000 tons, which comprises a methanol synthesis gas compression unit, a methanol synthesis unit, a methanol distillation unit, an analysis and testing laboratory, an air compressor station, a foam production station, tank farms, as well as other auxiliary systems, utility systems, environmental protection facilities, and storage and transportation infrastructure. Upon completion of the project, the production plan will allow for switching between \"165,000 tons per year of methanol (newly built) + 60,000 tons per year of synthetic ammonia (existing)\" and \"120,000 tons per year of synthetic ammonia (existing) + 200,000 tons per year of chemical alcohol (existing)\\". After fully implementing the various pollution prevention and environmental risk mitigation measures outlined in the environmental impact report, the adverse environmental impacts of the project construction can be mitigated and controlled. Therefore, from the perspective of environmental protection, our department agrees in principle to the nature, scale, technology, location of the construction project listed in the environmental impact report, as well as the environmental protection measures proposed. II. Environmental protection measures that need to be given priority attention during the project’s construction and operation phases. (1) Strictly implement the environmental protection requirement of using new technologies to support older ones. The exhaust gases from protein drying, germ drying, and fiber drying must be collected together. After being washed in a scrubber tower, they undergo heat exchange in a single-effect evaporator. Once the emission rates and concentrations of sulfur dioxide, sulfuric acid mist, particulate matter, and non-methane hydrocarbons meet the requirements of the secondary standards specified in Table 2 of the \"Integrated Emission Standards for Air Pollutants\" (GB16297-1996), these gases are released through exhaust stacks that are at least 15 meters high. The coal unloading area is equipped with wind and dust suppression nets that are at least 8 meters high. The regulating tanks in the sewage treatment plant shall be enclosed; waste gases must be collected centrally. After being treated in biological filters, the emission rates of ammonia and hydrogen sulfide must meet the limit values specified for malodorous pollutants in Table 2 of the \"Emission Standards for Malodorous Pollutants\" (GB14554-93), before being emitted through exhaust stacks with a height of no less than 15 meters. The project shall not be put into operation before the implementation of various governance measures aimed at integrating new elements with existing ones. (II) Strengthen environmental management during the construction period. Arrange the construction work hours in accordance with relevant regulations, and implement effective pollution control measures to prevent wastewater, exhaust gases, dust, noise, waste, and other pollutants from contaminating the surrounding environment during construction. The noise at the site boundary during the construction period must meet the corresponding standards specified in the \"Emission Standards for Environmental Noise at Construction Sites\" (GB12523-2011). (III) Strictly implement measures to prevent and control air pollution. During the construction period, construction activities and loading/unloading operations that generate dust are prohibited in windy weather; building materials should be covered while stored, and fully enclosed vehicles should be used to transport bulk building materials. The flash gas and vent gas from the methanol synthesis unit must be collected centrally before being discharged into the fuel gas network for use as fuel gas in flares. The non-condensable gases from the methanol distillation unit, as well as the waste gases generated during methanol loading and unloading, must be sent to a flare system for combustion. It is necessary to ensure that the concentration of methanol emissions meets the emission limits for organic characteristic pollutants in waste gases, as specified in Table 6 of the \"Emission Standards for Pollutants in the Petrochemical Industry\" (GB31571-2015). Effective measures shall be taken to control the unorganized waste gases in the plant area, to ensure that the emission concentration of total non-methane hydrocarbons meets the limit values for atmospheric pollutants at the enterprise boundary specified in Table 7 of the \"Emission Standards for Pollutants in the Petrochemical Industry\" (GB31571-2015). (IV) Strictly implement water pollution prevention and control measures. Domestic wastewater generated during construction is discharged into the sewage network, while construction wastewater is treated in sedimentation tanks; the supernatant fluid is then reused for sprinkling within the factory area to control dust. The wastewater from the methanol distillation tower during operation must be reused in the gasification unit and shall not be discharged externally. The wastewater from the methanol synthesis drum, floor cleaning wastewater, laboratory wastewater, and wastewater from the circulation system are treated at the existing wastewater treatment plant on site. The water pollutants ammonia nitrogen, suspended solids, and five-day biochemical oxygen demand must meet the indirect emission standards specified in the \"Emission Standards for Water Pollutants in the Starch Industry\" (GB25461-2010); meanwhile, the chemical oxygen demand must comply with the indirect emission standards set out in the \"Emission Standards for Water Pollutants in the Ammonia Synthesis Industry\" (GB13458-2013). After meeting these requirements, the wastewater is discharged into the Changchun Xinglongshan Wastewater Treatment Plant via the municipal sewage network, where it is further treated to meet regulatory standards before being released. (5) Strictly implement noise pollution prevention and control measures. Properly plan the overall layout of the plant site to control the noise level generated by equipment. Low-noise equipment shall be selected, and effective measures such as noise reduction, sound suppression, and vibration damping shall be taken to ensure that the noise levels at the factory boundaries meet the requirements of Class 3 and Class 4 as specified in the \"Emission Standards for Environmental Noise at the Boundaries of Industrial Enterprises\" (GB12348-2008). (VI) Strictly implement measures to prevent and control solid waste pollution. Waste catalysts and used engine oil generated by methanol synthesis plants are considered hazardous waste, and must be regularly sent to entities qualified to handle hazardous waste. During the storage, transfer, and transportation of such hazardous waste, the relevant requirements specified in the \"Standards for Pollution Control of Hazardous Waste Storage\" (GB18597-2001) and the \"Administrative Provisions on Transfer Forms for Hazardous Waste\" must be strictly followed. (7) Strictly implement measures to prevent and control groundwater pollution. In accordance with the relevant technical specifications, carry out impermeabilization work in non-pollution control areas, general pollution control areas, and key pollution control areas. Zoned anti-corrosion and anti-seepage treatment must be applied to the surfaces (sides) of areas such as the production unit area, tank area, and loading/unloading area within the plant ； High-quality pipes are used, and the pipelines are treated to prevent seepage, corrosion, and leaks ； Collect and dispose of pollutants on the ground in a timely manner ； Develop a groundwater monitoring plan and arrange groundwater monitoring wells appropriately to prevent pollution of the groundwater environment. (8) Strictly implement environmental risk prevention measures. An accident emergency pool with sufficient capacity should be established, and an environmental risk assessment should be carried out in accordance with the requirements of the \"Technical Guidelines for Environmental Risk Assessment of Construction Projects.\" The plant area must have a comprehensive three-level system for environmental risk prevention and control, an emergency plan for environmental risks should be developed and filed with the local environmental protection authorities, and regular environmental emergency drills should be conducted to prevent environmental pollution incidents. III. Project construction must strictly adhere to the environmental protection “three simultaneities” principle, which requires that environmental protection facilities be designed, constructed, and put into use simultaneously with the main project itself. Upon the completion of the project, the environmental protection facilities installed as part of the construction project must be inspected in accordance with relevant laws and regulations sowie the standards and procedures set by the Ministry of Ecology and Environment, and the inspection report must be made public in accordance with the law. The environmental protection facilities constructed as part of the project must pass inspection; otherwise, the main project shall not be put into production or use. IV. Once the environmental impact assessment report has been approved, if there are significant changes in the nature, scale, technology, location of the project, or in the measures taken to prevent ecological damage and control pollution, the environmental impact assessment report for that project must be submitted for approval again prior to such changes. If a construction project commences construction 5 years after the approval date of its environmental impact assessment report, such report must be submitted to our department for re-evaluation. V. As the entity responsible for disclosing information related to the environmental impact assessment of this construction project, your organization should establish a functional platform for public participation during the construction and operation phases of the project, so as to address promptly any environmental concerns raised by the public and meet their legitimate environmental demands. In accordance with the relevant provisions of the \"Plan for the Disclosure Mechanism of Environmental Impact Assessment Information for Construction Projects\", the corresponding environmental impact assessment information should be made public to the public in stages before the project starts, during its construction, and after it is completed, so as to actively accept social supervision. VI. Your organization shall carry out post-evaluation of the environmental impact of the project in accordance with relevant laws and regulations, conduct monitoring and evaluation of the actual environmental impacts generated by the project, as well as the effectiveness of measures taken for pollution control, ecological protection, and environmental risk prevention, and propose remedial plans or improvement measures. VII. The Jingkai District Branch of the Changchun Ecology and Environment Bureau is requested to be responsible for the supervision, inspection, and environmental management during the construction and operation phases of this project. VIII. Your unit shall, within 20 working days after receiving this approval, submit the approved environmental impact assessment report and the approval documents to the Changchun Ecology and Environment Bureau as well as the Economic Development Zone Branch of the Changchun Ecology and Environment Bureau, and shall subject itself to regular supervision and inspection by the ecological and environment authorities at all levels in accordance with relevant regulations.
