Potentially reducing regulatory burdens and encouraging pollution prevention: U.S. EPA withdraws “once in always in” policy for major sources under Clean Air Act

On Thursday, January 25, 2018, the U.S. Environmental Protection Agency (U.S. EPA) issued a guidance memorandum [PDF] withdrawing the “once in always in” policy for the classification of major sources of hazardous air pollutants (HAPs) under section 112 of the Clean Air Act. With the new guidance, sources of hazardous air pollutants previously classified as “major sources” may be reclassified as “area” sources when the facility limits its potential to emit below major source thresholds.
