(II) Implement various measures for air pollution control; after they come into operation, optimize and adjust the production processes as well as environmental protection measures based on actual conditions, to ensure that air pollutants are discharged within specified limits. (III) Hazardous waste generated during construction and operation must be managed in accordance with laws, regulations, and relevant policy requirements. (IV) Strengthen environmental risk prevention and emergency response measures. Formulate emergency response plans for sudden environmental incidents, and file them with the environmental protection administrative department as required. The final capacity of initial rainwater collection tanks, accident tanks, etc., is determined by the design firm in accordance with relevant standards, to ensure that wastewater is not discharged in the event of an accident. Regularly conduct emergency training and drills for environmental risks, and stockpile necessary emergency supplies. III. During the project construction phase, environmental supervision should be carried out, and reports on this supervision should be submitted regularly to environmental protection agencies at all levels; such supervision reports shall be included as part of the requirements for environmental protection assessment upon project completion. IV. The construction of this project must strictly adhere to the environmental protection principle of \"design, construction, and commissioning simultaneously\" for environmental protection facilities and the main project, and all relevant environmental protection measures must be implemented. After the project is completed, a pollution discharge permit must be obtained before starting up the production facilities or discharging pollutants in practice. Conduct the environmental protection acceptance upon completion in accordance with the prescribed procedures. V. The project owner is the entity responsible for implementing environmental protection measures and disclosing environmental information throughout the entire process of project selection, construction, and operation. It shall, in accordance with requirements such as the \"Plan for the Disclosure Mechanism of Environmental Impact Assessment Information for Construction Projects,\" disclose the relevant environmental impact assessment information in a lawful and regulated manner, ensure smooth channels for public participation and social oversight, and safeguard the environmental rights of those who may be affected by the project. VI. 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 pollution and ecological damage, the environmental impact assessment report for that project must be submitted for approval again. If more than 5 years have passed since the approval of the environmental impact assessment report and construction is only planned to begin at that time, the report must be submitted to our department for re-examination. VII. In accordance with the requirements of the \"Procedures for Supervision and Management of Environmental Protection during and after the Construction of Projects (Trial)\\", the Yulin City Ecology and Environment Bureau and the Shenmu City Ecology and Environment Bureau are responsible for the supervision and management of this project during and after its implementation. 8. Your company shall, within 20 working days upon receiving this approval, submit the approved environmental impact assessment report to the Yulin City Ecology and Environment Bureau and the Shenmu City Ecology and Environment Bureau for record-keeping, and shall submit itself to supervision and inspection by ecological and environment authorities at all levels in accordance with relevant regulations. Shaanxi Provincial Department of Ecology and Environment, August 13, 2019. The proposed site for the project is located within the land reserved by Shaanxi Coal Group in the Qingshui Industrial Park of the Yushen Industrial Zone ； The total investment for the project is 3,203.96 million yuan, of which 147.838 million yuan is allocated to environmental protection measures, accounting for 4.6% of the total investment. The project primarily uses raw coal from the Xiao Baodang No. 1 and No. 2 coal mines as well as the Caojiatan coal mine; this coal is ground into powder and then treated using low-temperature pyrolysis technology. The resulting powdered coke is used in gasification processes for downstream applications. The coal tar components are processed through a suspended-bed combined hydrogenation process to produce coal tar products. The waste heat generated by the processing equipment is recovered and utilized in the 1.8 million tons per year ethylene glycol production facility. The construction includes a 1.2 million tons per year pulverized coal pyrolysis unit, a 500,000 tons per year coal tar hydrogenation complex, a 100,000 tons per year gas desulfurization unit, a 420,000 tons per year process wastewater treatment plant, as well as supporting storage, transportation, and power supply systems. The project’s utility and auxiliary production facilities rely on the 1.8 million tons per year ethylene glycol plant. On July 24, the groundbreaking ceremony for the first phase of the demonstration project on the utilization of coal in order to produce new chemical materials, namely an 1.8 million tons per year ethylene glycol production facility, was held at the Qingshui Industrial Park in Yulin City. This marked the full transition of the project’s construction from the design stage to the actual construction phase. The “Demonstration Project for the Production of Chemical New Materials through the Differential Utilization of Coal” undertaken by Yulin Chemical of Shaanxi Coal Group is currently the largest coal chemical project under construction in the world. This project was planned and developed by Shaanxi Coal Group, taking advantage of the resource advantages in northern Shaanxi, following a completely new industrial organization model. The total area of the project is approximately 13 square kilometers, and it includes 27 processing units along with the associated utility systems. These units are mainly used for the medium- and low-temperature pyrolysis of 15 million tons of coal, as well as the production of 5.6 million tons of methanol, 1.8 million tons of ethylene glycol, 2 million tons of polyester, and 2 million tons of olefins; downstream products are also manufactured using these materials as intermediate inputs. The annual amount of coal processed exceeds 20 million tons, with an estimated total investment of over 120 billion yuan. The project will be constructed in two phases and four stages, with the investment for Phase 1 amounting to approximately 70 billion yuan. The 1.8 million tons per year ethylene glycol project is the first phase of this initiative, and it is also the largest coal-based ethylene glycol production facility under construction worldwide. The estimated investment for this project is 26.5 billion yuan; production of qualified products is scheduled to begin in June 2021, with the entire project expected to be completed and operational by 2025. The 1.8 million tons per year ethylene glycol project utilizes Collin’s patented dry powder gasification technology, as well as Japan’s Takahashi’s patented technology for producing ethylene glycol from syngas. Shaanxi Coal Group Yulin Chemical Co., Ltd. and Nippon Kako Kagaku Co., Ltd. jointly invested in establishing Shaanxi Coal Group Yulin Chemical Yugao Chemical Co., Ltd., to build and operate facilities for the production of oxalate esters as well as for the hydrogenation of oxalate esters to produce ethylene glycol. This is the largest Sino-Japanese joint venture to be established in Shaanxi since 2005. The second phase of the first stage of the demonstration project for the use of coal in various ways to produce new chemical materials consists of an olefin production facility with a capacity of 2 million tons per year, along with related deep-processing units; it is expected to be completed and put into operation by the end of 2023. Phase 2 focuses on coal pyrolysis and is also divided into 2 stages: the first stage is the pyrolysis startup project, which will be constructed simultaneously with the ethylene glycol project, with completion and commissioning scheduled for June 2021 ； In the second phase, the scale of pyrolysis will be increased to 15 million tons, and the coal tar industry chain will be expanded to produce downstream products containing arylene compounds. Construction is scheduled to begin by the end of 2021, with operation to start by the end of 2025.
