The proposed ministerial regulation aims to update and replace the existing standards for odor emissions from factories, originally established in 2005. This regulatory overhaul is essential for addressing the evolving industrial landscape and ensuring environmental protection. Here’s a detailed breakdown:
Key Differences Between the 2005 Regulation and the Proposed Regulation
1. Updated Definitions. The new draft provides clearer definitions for “odor” and introduces the term “odor sample,” which is crucial for accurate monitoring and enforcement. The definitions now explicitly include both human sensory detection and analytical instruments, ensuring comprehensive coverage.
2. Expansion of Factory Types. The regulation expands the scope to include rubber production factories using natural rubber, aligning with the 2019 Ministry of Natural Resources and Environment’s standards. This inclusion reflects the growing need to regulate industries with significant odor emissions.
3. Measurement Methods. The draft regulation shifts from solely relying on ASTM and JIS standards to include sensory tests (olfactory analysis). This change ensures a more localized and relevant approach to measuring odors, enhancing the accuracy and relevance of the results.
4. New Odor Intensity Standards. The regulation introduces specific limits for odor intensity at factory boundaries and exhaust points, differentiated by whether the factory is within or outside industrial zones. For example, within industrial zones, the odor concentration at factory boundaries should not exceed 30 units, while at exhaust points, it should not exceed 1,000 units. For rubber factories, stricter limits apply, reflecting their higher potential for odor emissions.
5. Enforcement and Compliance. The draft regulation strengthens enforcement mechanisms by enabling the Department of Industrial Works to conduct odor measurements based on complaints or suspicions of non-compliance. It also allows for the establishment of specialized odor testing committees to oversee compliance.

Implications and Insights
This regulatory update is a significant step toward enhancing Thailand’s environmental governance. By modernizing odor standards and expanding their scope, the government is addressing both current industrial practices and the growing public concern over environmental quality. The shift toward sensory tests and the inclusion of more industries indicate a proactive approach to managing industrial emissions.
The proposed regulation reflects Thailand’s commitment to aligning industrial growth with environmental protection. By ensuring clearer definitions, broader coverage, and more effective enforcement, the regulation will likely improve air quality and public health in areas affected by industrial activities. This move also signals Thailand’s readiness to adopt more sophisticated and localized methods for environmental monitoring, ensuring that regulatory standards keep pace with industrial advancements.
