Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act Rule Summary

EPA is proposing a rule to implement the clear language of the Clean Air Act that allows a “major source” of hazardous air pollutants (HAP) to reclassify as an “area source” after acting to limit emissions.

This proposal would relieve reclassified facilities from regulatory requirements intended for much larger emitters. It would also encourage other sources to evaluate their operations and consider changes that would enable them to further reduce HAP emissions and reclassify.
