November 9, 2020 by Hunter Johnston Air Chemicals Regulations

On October 1, 2020, the Environmental Protection Agency (EPA) finalized text for a final rule that proposed to change the way facilities that emit hazardous air pollutants (HAPs) are regulated under the Clean Air Act.[i] The rule, titled Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act, purports to implement a plain language interpretation of Section 112 of the Clean Air Act.[ii] In practical effect, the final rule provides that a “major source” can reclassify to “area source” status at any time after reducing its actual or potential hazardous air pollutants (HAP) emissions to below the major source threshold of 10 tons per year (tpy) of any single HAP and 25 tpy of any combination of HAPs.[iii] Additionally, the rule amends Clean Air Act requirements regarding compliance dates, notification, and record keeping.[iv]
