Recently, the Ministry of Ecology and Environment issued a "Notice on the issuance of the principles of approval of environmental impact assessment documents for steel/coking, modern coal chemical, petrochemical and thermal power construction projects", revised the original principles of approval of environmental assessment documents for steel, petrochemical and thermal power construction projects, developed the principles of approval of environmental assessment documents for modern coal chemical construction projects, replacing the environmental access conditions for modern coal chemical construction projects (for trial implementation).
In the revision process, the approval principles according to the existing ecological and environmental management of the new situation and new requirements, clearly specify the four industries of construction projects project site selection, technological transformation and upgrading and environmental impact assessment of greenhouse gas emissions, to further coordinate development and protection, firmly maintain the bottom line of green development.
Site selection regulations: pay close attention to the Yangtze and Yellow River basins to promote industrial clustering
The Yangtze and Yellow River basins are important ecological barriers and economic regions in China, and the ecological protection related contents of the two basins have become the focus of this revision.
The approval principles are clear, petrochemical, modern coal chemical project site shall not be located within 1 km of the Yangtze River dry tributary shoreline, the Yellow River dry tributary shoreline control area and other areas prohibited by law and regulations.
This provision emphasizes the project's risk prevention and control, not only in line with the "Yangtze River Protection Law" and "Yellow River Protection Law" in the relevant project requirements, but also closely related to the project characteristics of the petrochemical and modern coal chemical industry. Luo, a senior engineer of the Environmental Engineering Evaluation Center of the Ministry of Ecology and Environment, told reporters that the distribution of petrochemical and coal chemical projects in the Yangtze and Yellow River basins is relatively concentrated, and the projects usually involve a large number of petroleum, methanol, ethylene, aromatics and other hazardous chemicals, which are too close to the shoreline will greatly increase the risk to the water environment.
In order to implement the ecological environmental protection requirements of the Yangtze and Yellow River basins, new requirements have been added for the siting of projects in the steel and coking industries. Zhang Chengzhou, a senior engineer at the Environmental Engineering Evaluation Center of the Ministry of Ecology and Environment, introduced the approval principles to clarify the Yangtze River Economic Zone and the Yellow River key areas for new and expanded steel smelting projects into compliance parks.
In the approval principles of the project site selection regulations, in addition to the ecological protection of the Yangtze and Yellow River basins, but also highlight the promotion of industrial projects into the park, to further improve the concentration of project distribution.
Among them, the petrochemical and modern coal chemical industries continue to be reserved to enter the park, in line with the park planning environmental assessment requirements, the coking industry new industrial park, in line with the park planning and planning environmental assessment site selection requirements, to encourage steel smelting projects rely on the existing production base clustering development, to encourage new coking projects and steel, chemical integration.
Technical requirements: emphasize green upgrade and transformation, set consistent goals
The four industries, as high-polluting and high-emission industries, are the key industries for pollutants and carbon dioxide emissions. In this revision, in order to promote the green and low-carbon development of the industry, the approval principles of the construction project on the level of cleaner production has put forward specific requirements.
In contrast, the revision proposed four industries should use advanced and applicable technology and equipment, the requirements of clean production is very specific. As the clean production standard system of iron and steel, thermal power is relatively mature, petrochemical, modern coal chemical industry clean production standard system is not perfect, the expression is slightly different, but the overall goal of promoting the green development of the industry is the same.
Among them, new and expanded iron and steel, coking construction projects unit product energy consumption, material consumption, water consumption, comprehensive utilization of resources, pollutant emissions and other indicators should reach the domestic advanced level of clean production.
Modern coal chemical and petrochemical construction projects product consumption, energy consumption, water consumption, pollutant emissions and comprehensive utilization of resources should reach the industry's advanced level.
New thermal power expansion projects power supply coal consumption and air pollutant emissions should reach the benchmark level of clean and efficient use of coal, unit power generation water consumption, wastewater discharge, comprehensive utilization of resources and other indicators should reach the domestic advanced level of clean production.
Carbon reduction exploration:New greenhouse gas environmental assessment and carbon reduction technology application
"Improve the statistical survey, accounting verification and supervision system of emission sources, and incorporate greenhouse gas control into the management of environmental evaluation." In the "Opinions on Deepening Pollution Prevention and Control", the inclusion of greenhouse gases in environmental assessment has become an important measure to further promote peak carbon action.
In this revision, Article 6 of the four industry approval principles clearly stipulates the inclusion of greenhouse gas emissions in the environmental impact assessment of construction projects, and proposes that the focus of greenhouse gas environmental assessment is to calculate the greenhouse gas emissions of construction projects. Ran Lijun, a senior engineer at the Environmental Engineering Evaluation Center of the Ministry of Ecology and Environment, believes that the imperfect technical system of greenhouse gas evaluation and the lack of access index requirements are among the reasons why the environmental evaluation of greenhouse gases focuses mainly on greenhouse gas emissions of construction projects.
In fact, since 2021, the Ministry of Ecology and Environment has carried out a pilot project on the environmental impact assessment of carbon emissions from key industrial construction projects. Seven provinces (cities), including Hebei and Jilin, are conducting pilot projects around key industries such as electricity, iron and steel, building materials, non-ferrous metals, petrochemicals and chemicals.
Shuai Wei, a senior engineer at the Environmental Engineering Evaluation Center of the Ministry of Ecology and Environment, said that as one of the pilot industries for the environmental impact assessment of carbon emissions, thermal power has made the first exploration of the technical methods and management requirements for the assessment. Based on the current technical level and deployment arrangement, the main focus is on the calculation of project greenhouse gas emissions, laying the foundation for the subsequent "double control" of total greenhouse gas emissions and emission intensity of the industry.
In the four industry approval principles, also emphasizes the demonstration and application of carbon reduction technologies. For example, thermal power construction projects proposed to encourage carbon collection, utilization and sealing engineering pilot demonstration, modern coal chemical construction projects to encourage conditional areas, enterprises to carry out green hydrogen coal chemical project coupling, high concentration of carbon dioxide collection, utilization and sealing to reduce pollution and carbon co-processing project demonstration, iron and steel and coking construction projects to explore hydrogen metallurgy, carbon dioxide collection and utilization of integrated pilot demonstration.
