1.      The air emission technology approval letter is an approval that companies generating production exhaust gases must have. This approval pertains to the standards for managing and monitoring the environment.

2.      Companies that treat exhaust gases or use chimneys or generators, and are also required to obtain an AMDAL/UKL-UPL/RKL-RPL Detailed Report, must obtain the air emission technology approval letter and SLO for air emissions treatment.

3.      If the air emission technology approval letter has not been drafted, the environmental impact assessment (EIA) approval letter cannot proceed. The EIA approval letter is one of the requirements for applying for a business license.

4.      Activities related to exhaust gas treatment include combustion processes through boilers, power plants, generators, incinerators (using coal, natural gas, oil, biomass), or other production-related exhaust gas activities。

5.      The air emission technology approval letter is essentially divided into two types of reports: the technical standard report and the technical analysis report. The type of report is determined based on the scope of operations, such as:

a.      Technical Standard Report

–        This refers to the scope of operations with high air emission impacts, as outlined in Attachment X of the 2021 Minister of Environment Regulation No. 5, for example, 13132 : Textile Finishing Industry.

b.      Technical Analysis Report

–        05100 Business Scope: Coal Mining

–        17011 Business Scope: Pulp Industry

–        35111 Business Scope: Power Generation

–        Other scope of operations according to Attachment X of the 2021 Minister of Environment Regulation No. 5.

6.      Before applying for the air emission technology approval letter, a pollutant emission control technology plan must be in place. Common equipment for controlling gaseous emissions includes scrubbers, NSCR (Non-Selective Catalytic Reduction), and SCR (Selective Catalytic Reduction). For controlling particulate emissions, common equipment includes ESP (Electrostatic Precipitators), baghouse filters, fabric filters, and cyclonic separators.

7.      The air emission technology approval letter has no validity period. However, if there are changes in the scope of operations, a new air emission technology approval letter must be drafted.

8.      When the commissioning test period has ended, the company must submit a report on the installed emission control equipment in order to obtain the SLO (which is one of the conditions for handling air emissions)
