  The rubber and plastic products industry is my country's traditional manufacturing industry and occupies an important position in the world industry. There are many kinds of rubber and plastic products, and their extensive use in military industry, aerospace, and civil use has irreplaceable strategic significance. This standard incorporates odorous pollutants into the pollution discharge permit supervision system according to the industry's production process and characteristics of production and discharge; by sorting out the pollutant discharge standards for rubber products, artificial leather and synthetic leather, synthetic resin and other industries, the method for determining the permit limit is clarified; The classification management of licenses respectively stipulates key and simplified management of pollutant discharge permit requirements, clarifies pollution prevention and control requirements, and puts forward environmental management requirements such as self-monitoring by pollutant discharge units, environmental management account, and pollutant discharge permit execution report. The release and implementation of this technical specification is of great significance to improving the level of industrial pollution prevention and refined management of rubber and plastic products, and promoting the issuance of industrial pollution discharge permits.

  The shoemaking industry mainly includes the production of textile fabric shoes, leather shoes, plastic shoes, rubber shoes and other kinds of shoes. There are many enterprises and many small enterprises. The volatile organic compounds produced by the adhesives, treatment agents and other materials used in the production process of the shoemaking industry are the main sources of pollutants, especially the use of solvent-based adhesives in the upper and sole bonding process is large, and some products use treatment agents at the same time. major source of volatile organic compound emissions. This technical specification defines the discharge port corresponding to the bottom bonding process of the key management sewage unit as the main discharge port. This technical specification mainly focuses on waste gas management and control, while taking into account waste water, soil and groundwater, solid waste and other aspects. Etc., clarified the method of determining the permitted emission limit and compliance determination, as well as the environmental management requirements such as self-monitoring, environmental management ledger and emission permit execution report, detailed regulations on the operation management requirements of waste gas and wastewater, and proposed system Reference requirements for feasible technologies for pollution prevention and control of sewage discharge units in the footwear industry. The release and implementation of this technical specification will play an important role in improving the overall pollution prevention and control level of the footwear industry, promoting the industry's standardized environmental management, guiding applications and issuing pollution discharge permits.

  "Technical Specifications for Railway, Ship, Aerospace and Other Transportation Equipment Manufacturing Industry" clarifies the emission concentration limits, compliance determination technical methods, self-monitoring, environmental management Environmental management requirements such as ledger and execution report, combined with the characteristics of volatile organic compounds as the main waste gas pollutants in the industry, refined the operation management requirements of organized and unorganized emissions of volatile organic compounds, and proposed solvent-based paint spraying waste gas and spray paint The requirements for automatic monitoring facilities for volatile organic compounds at the organized discharge port of drying exhaust gas. In addition, due to the release of the "List of Fixed Pollution Source Pollutant Discharge Permit Classification Management (2019 Edition)", it is tentatively estimated that more than 110,000 pollutant discharge units involving general process surface treatment (painting) have been newly included in the scope of pollutant discharge permit management. Considering that this technical specification covers a wide range of industries, involves many coating methods, and has a relatively comprehensive content, the content of the technical specification for surface treatment (painting) is added in Appendix A of the technical specification for the reference and implementation of surface treatment (painting) pollutant discharge units (excluding the Existing industry pollutant discharge permit application and issuance of pollutant discharge units, such as automobile manufacturing, furniture manufacturing industry pollutant discharge units). After the implementation of the technical specifications, the first is to make the transportation equipment manufacturing industry "evidence-based", laying a solid foundation for the realization of the full coverage of fixed pollution source pollution discharge permits; the second is to vigorously promote the reform of the industry's pollution discharge permit system and comprehensively improve the industry's environmental management level .

  Rare rare earth metal smelting belongs to the non-ferrous metal smelting industry, mainly including: 3231 tungsten and molybdenum smelting, 3232 rare earth metal smelting, 3239 other rare metal smelting pollutant discharge units in the national economic classification.
