The Ministry of Environment (MoE) in South Korea updates the ‘Regulations on Emissions Survey and Calculation Factors of Chemical Substances’ under the Chemical Substances Control Act.

The scope for emission survey is based on the Annex 1, which is categorized according to the Korea Standard of Industry Classification. For point pollution sources, the facilities subject to the emission survey are the ones with the permission to have emission facilities, but it can be exempted based on substance category and tonnage band. Also, nonpoint pollution sources can be included for the emission survey if necessary.

The chemical substances subject to emission survey are listed in Annex 2, and it should fall under any of the followings:

1. Chemical substances and products produced at facilities
2. Raw materials and additives used at facilities
3. Process auxiliary substances used at facilities
4. Chemical substances kept and stored at facilities
5. Wastes processed at waste treatment plants
6. Chemical substances used in other facilities (for example, chemical substances used for wastewater treatment, and maintenance and repair of facilities and equipment)

The validity of this regulation will be reviewed every three years from January 1, 2023.

The amendment came into effect immediately.
