Thailand CEMS Regulations 2024-2026: 13 Factory Types for POMS

Thailand's environmental landscape is shifting rapidly. With the rise of PM2.5 concerns and international climate commitments, the CEMS (Continuous Emission Monitoring System) laws have transitioned from regional enforcement to a nationwide mandate. ASE provides this essential briefing for factory owners and environmental managers.

The 13 Regulated Factory Types

The Ministry of Industry Notification (2022) identifies 13 specific industrial categories that must install and maintain a CEMS:

1. Power Plants: Facilities with a capacity of 10 MW or higher.
2. Industrial Boilers: Steam generation units exceeding 30 tons per hour.
3. Petrochemical Plants: All facilities with active combustion processes.
4. Petroleum Refineries: Every emission-relevant unit within the refinery.
5. Natural Gas Processing Plants:
6. Iron and Steel Industry: Large-scale smelting and reheating furnaces.
7. Cement Manufacturing: Specifically the kiln sections.
8. Pulp and Paper Mills: Facilities meeting specific production thresholds.
9. Glass and Mirror Factories: Using high-temperature melting furnaces.
10. Waste Incinerators: Both municipal and industrial hazardous waste facilities.
11. Lead Smelting Plants:
12. Copper Smelting Plants:
13. Sulfuric Acid Plants:

Critical Deadlines: 2024 to 2026

• June 9, 2024: This was the final deadline for existing factories (operational before 2022) to complete their hardware installation and cloud linkage with the DIW.
• 2025-2026: New localized regulations will take effect in the Bangkok Metropolitan Region. These mandates will likely lower the threshold for compliance to capture smaller factories contributing to regional PM2.5 levels.
• Data Availability: The DIW requires that the POMS (Pollution Online Monitoring System) receives valid data for at least 80% of the facility's operational hours daily.

Technical Standards & Verification

To ensure data integrity, all CEMS installations must comply with rigorous international standards adopted by the DIW: - US EPA Performance Specifications: Systems are evaluated based on PS 2 (NOx/SO2), PS 3 (O2/CO2), PS 4 (CO), and PS 11 (Particulate Matter). - Annual RATA Audits: A mandatory yearly audit where the CEMS data is compared against an independent reference method to ensure ongoing accuracy.
