Introduction of GB 37822-2019

Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is developed with a view to implementing the Environmental protection law of the People's Republic of China and the Law of the People's Republic of China on the prevention and control of atmospheric pollution, controlling environment pollution, improving environmental quality and enhancing control and management of fugitive emission of VOCs. This standard specifies the fugitive emission control requirements for VOCs-containing materials storage, VOCs-containing materials transfer and transport and VOCs-containing materials in technological process, as well as VOCs leakage control requirements for equipment and pipeline components, the fugitive emission control requirements for VOCs on uncovered liquid surface, as well as requirements for collection and treatment system of exhaust gas via fugitive emission of VOCs and pollution monitoring requirements for the company's plant and surrounding areas. This standard is issued for the first time. The fugitive emission control of VOCs shall be executed in accordance with the provisions of this standard by new facilities since July 1, 2019, and by the existing facilities since July 1, 2020. Upon approval of provincial people's government, all regions may implement this standard in advance according to the need of local environmental protection and economic and technical conditions. This standard specifies the basic requirements for fugitive emission of VOCs. Local provincial people's government may formulate local pollutant emission standards for the items not specified in this standard; and it may also formulate local pollutant emission standards stricter than this standard for the items specified in this standard. Annex A of this standard is informative. This standard is developed by the Department of Air Environment and the Department of Laws and Regulations and Standards under the Ministry of Ecology and Environment. This standard was approved by the Ministry of Ecology and Environment on April 16, 2019. This standard is implemented from July 1, 2019. The Ministry of Ecology and Environment is in charge of the explanation of this standard. Standard for fugitive emission of volatile organic compounds 1 Application scope This standard specifies the fugitive emission control requirements for VOCs-containing materials storage, VOCs-containing materials transfer and transport and VOCs-containing materials in technological process, as well as VOCs leakage control requirements for equipment and pipeline components, the fugitive emission control requirements for VOCs on uncovered liquid surface, as well as requirements for collection and treatment system of exhaust gas via fugitive emission of VOCs and pollution monitoring requirements for the company's plant and surrounding areas. This standard is applicable to the fugitive emission management of VOCs in existing facilities or production facilities involving fugitive emission of VOCs, as well as the environmental impact assessment, the environmental protection facilities design, the completion environment protection acceptance, and the emission permit issuance of construction projects involving fugitive emissions of VOCs, and fugitive emission management of VOCs after their production. If the national pollutant emission standards issued by the state have stipulated the fugitive emission control of VOCs, they shall be implemented according to the industry pollutant emission standards. If the VOCs fugitive emission control requirements specified in this standard cannot be met due to safety factors or special process requirements, other equivalent pollution control measures may be taken and reported to the local ecological environment authority or implemented in accordance with the relevant requirements of the pollutant emission permit. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard.
