1. The Ministry of Ecology and Environment recently issued the "Principles for the Approval of Environmental Impact Assessment Documents for Modern Coal Chemical Industry Construction Projects..." The purpose of the "Principles for the Approval of Environmental Impact Assessment Documents for Contemporary Coal Chemical Industry Construction Projects" is to improve management efficiency, unify management standards, strengthen source prevention and control, promote collaborative efficiency in pollution reduction and carbon reduction, guide local ecological environment departments to strengthen environmental impact assessment management for construction projects, promote regional environmental quality improvement, and promote green development. Scope of application: Applicable to new construction, renovation, and expansion projects that produce synthetic natural gas, synthetic oil, methanol, olefins, aromatics, ethylene glycol, and other downstream chemical products through coal (coke) gasification and liquefaction as the leading industry. The specific industry scope is coal to synthetic gas and coal to liquid fuel in the "Classification Management List for Environmental Impact Assessment of Construction Projects (2021 Edition)" for coal processing 252. The approval of the environmental impact assessment document for the low-grade coal quality utilization project (excluding blue charcoal) shall be carried out in accordance with the reference. Policy requirements: The project should comply with relevant laws and regulations on ecological environment protection, statutory planning, as well as policies related to industrial structure adjustment, regional and industry carbon peak and carbon neutrality goals, total coal consumption control, and total emissions control of key pollutants. It should also comply with relevant industrial planning such as the layout plan for innovative development of contemporary coal chemical industry. Site selection planning: Project site selection should comply with the requirements of ecological environment zoning control. New and expanded projects should be located in legally and compliantly established industrial parks, and meet the requirements of park planning and environmental impact assessment. It shall not be located within one kilometer of the main and branch banks of the Yangtze River or within the control range of the main and branch banks of the Yellow River, which are prohibited by laws and regulations. It should avoid the ecological protection red line and be as far away as possible from environmentally sensitive areas such as residential areas, hospitals, schools, etc. Process technology and equipment design: New and expanded projects should adopt advanced and applicable process technology and equipment, and the unit product material consumption, energy consumption, water consumption, pollutant emissions, and comprehensive resource utilization should reach the industrys advanced level. New projects should reach the benchmark level of high-efficiency utilization of clean coal. Strengthen water-saving measures, reduce the amount of fresh water used, prioritize the use of recycled water and mine water as production water in areas with conditions, and prioritize the use of water-saving technologies such as air cooling and closed circulation in water scarce areas. New projects should undertake demonstration tasks in areas such as efficient utilization of coal quality, coupled utilization of resources
