This post is an update to our October 2, 2020 blog post regarding U.S EPA’s final rule overturning U.S. EPA’s ‘Once In, Always In’ policy for major sources of hazardous air pollutants. Notably, the final rule was published in the November 19, 2020 Federal Register and, thus, the rule becomes effective on January 19, 2021.

Please contact us with any questions or for assistance regarding your facility’s permitting and emission requirements in light of U.S. EPA’s new rule.
