Discussion on a topic in the technical guidelines and standards for environmental impact assessment! ! !

The last edit to this post was made by 20036820 on 2009-11-4 at 13:11. A correction: all the standards you mentioned are national standards; GB denotes mandatory standards that must be followed； GB/T denotes a recommended **standard (in such standards, certain provisions are mandatory and must be followed, while others serve as references). 】What is stated in the guidelines is correct... In terms of the standard system, the environmental quality standards and pollutant emission standards within environmental protection standards exist at only two levels: **national (GB) and local (DB)**. It is at these national and local levels that administrative supervision is exercised, with DB standards being higher than GB standards. In addition to **national and local standards**, product quality standards also include industry-level standards and enterprise-level standards. Among the standards for products, enterprise standards are higher than DB standards, which in turn are higher than industry standards; and GB standards. The code for enterprise standards (QB) refers to the standards that a company uses for manufacturing a particular product when there are no national, regional, or industry standards available for reference. In such cases, the company must establish its own guidelines and standards to guide the production of that product. If there are ** or industry benchmarks, then these standards can be adopted as those of one’s own company, serving as the company’s own standards. The order in which GB, DB, and industry standards are referenced is as follows: first, DB is applied; if there is no DB, then the industry standard is used. If neither of the first two is applicable, the national standard is used. If none of the first three apply, a standard is developed on one’s own, and it is then submitted to the Standards Department of the Quality Supervision Bureau for approval and registration, thereby creating an enterprise standard. Hehe, GB refers to the standards set by administrative agencies such as the Quality Supervision Bureau for supervision purposes; DB denotes standards established in more developed regions that are higher than those set by industry bodies, with the aim of improving the quality of certain products within those regions. Industry standards have different prefix codes. Here are the codes for industry standards in the People’s Republic of China: Serial Number, Name of Industry Standard, Code for Industry Standard, and Competent Department. 1.

Note: Industry standards are divided into mandatory and recommended standards. The codes listed in the table represent mandatory industry standards; the codes for recommended industry standards are obtained by adding “/T” after the code of the mandatory standard. For example, the code for recommended industry standards in the agricultural sector is NY/T.

20036820: First of all, thank you for your assistance. Power plants are required to comply with GB13223-1996 \"Emission Standards for Air Pollutants from Power Plants\", while cement plants must adhere to GB4915-1996 \"Emission Standards for Air Pollutants from Cement Plants\". Do these two standards constitute industry standards?

My understanding is that this standard is the national standard for this industry, haha

There are industry standards and comprehensive emission standards that are not applied concurrently. If there are industry standards, those shall be followed; if no such standards exist, the comprehensive emission standards shall be applied ； Where local standards exist, those **standards** are not followed.
