Summary
The EPA is giving Oklahoma the authority to enforce federal air pollution standards for hazardous chemicals in the state, rather than having the EPA do it directly. This means Oklahoma will take over responsibility for monitoring and regulating dangerous air pollutants that can harm people's health, starting February 2, 2026.
Key Points
- 1Oklahoma receives permission from the EPA to enforce the National Emission Standards for Hazardous Air Pollutants (NESHAP) within the state

- 4Oklahoma must now ensure that these facilities meet the same federal air quality standards and submit compliance reports to the EPA
