This Standard applies to air pollutant emission control of existing auto parts manufacturing enterprises, as well as environmental impact assessment of construction projects of auto parts manufacturing enterprises, design of environmental protection facilities, environmental protection acceptance of completed construction, issuance of pollution permits, and management of air pollutant emissions after commissioning.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The gas- species that are not indicated are calculated as toluene. 3.4 control facilities for air pollutants The effective pollution control facilities such as dust removal equipment, 4.4.5 The fugitive emission control requirements of open liquid VOCs shall meet the requirements of GB 37822. Waste gas discharged from wastewater storage and treatment facilities shall meet the requirements of Table 1. 4.4.6 The waste gas collection and treatment system shall operate synchronously with the production process equipment. When the exhaust gas collection-treatment system fails or is overhauled, the corresponding production process equipment shall stop running. Put it into use synchronously after the overhaul is completed. If the production process equipment cannot be stopped or cannot be stopped in time, emergency waste gas treatment facilities shall be set up or other alternative measures shall be taken. 4.4.7 The enterprise shall establish a ledger in accordance with the requirements of HJ 944. Record the purchase, storage, use and processing of VOCs materials every month, and keep them for at least 3 years for inspection by the competent authority. The data to be recorded includes: a) The content of VOCs in each VOCs material, the monthly usage, recycling and disposal of VOCs materials, the recovery and disposal methods, the VOCs content in the materials shall be subject to the VOCs content test report issued by a qualified testing authority; b) The operating time of the waste gas collection system and pollution control facilities, and the waste gas treatment volume. The adsorption device shall record the type of adsorbent, the replacement/regeneration cycle and the replacement amount, and the operating temperature. The thermal combustion device shall record the combustion temperature and the residence time of the flue gas daily. The catalytic oxidation device shall record the type of catalyst, the date of catalyst replacement, and the operating temperature. For other pollution control equipment, maintenance items shall be recorded. The main operating parameters shall be recorded daily; c) Replacement and disposal records of filter materials.5 Air pollutant monitoring requirements5.1 General requirements 5.1.1 Enterprises shall, according to relevant laws, "Environmental Monitoring Management Measures" and HJ 819 and other regulations, establish an enterprise monitoring system and formulate a monitoring plan to conduct self- monitoring of pollutant discharge state and its impact on surrounding environmental quality. Keep original monitoring records. Announce monitoring results. 5.1.2 The requirements for the installation of automatic pollutant discharge monitoring equipment for new enterprises and existing enterprises shall be implemented in accordance with relevant laws and the "Administrative Measures for Automatic Monitoring of Pollution Sources". 5.1.3 Enterprises shall design, construct, and maintain permanent sampling ports, sampling test platforms and sewage outlet signs in accordance with the requirements of environmental monitoring management regulations and technical specifications. 5.1.4 Air pollutant monitoring shall be carried out at the specified monitoring location. If there are waste gas treatment facilities, they shall be monitored before and after the treatment facilities. 5.2 Monitoring sampling and analysis methods 5.2.1 The number of sampling points and location settings for VOCs monitoring of exhaust cylinders shall be implemented in accordance with the provisions of GB/T 16157, HJ/T 397, HJ/T 373 and HJ 732. 5.2.2 When monitoring fugitive emissions of VOCs in the plant, the monitoring shall be carried out at a position 1 m outside the discharge openings such as factory doors, windows, vents, and other openings (holes), and 1.5 m above the ground. If the plant is incomplete (if there is a roof and no walls), the monitoring shall be carried out at a position where the wind direction is 1 m down the operating station and 1.5 m above the ground. 5.2.3 The monitoring of the average concentration of NMHC in any one hour in the plant area adopts the method specified in HJ 604. The average value is obtained by sampling for 1 hour, or 3~4 samples are collected at equal intervals within 1 hour to calculate the average value. The monitoring of the concentration value of NMHC at any one time in the plant area shall be carried out in accordance with the relevant regulations of portable monitoring instruments. 5.2.4 The analysis and determination of air pollutants shall be carried out in accordance with the method specified in Table 4. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
