EPA Policy Victory: ‘Once In, Always In’ Withdrawn
In a victory for industry, the U.S. Environmental Protection Agency in January eliminated the “once in, always in” policy under the Clean Air Act.
The policy required “major sources” -- facilities that release at least 10 tons per year of a single hazardous air pollutant or 25 tons of any combination of HAPs each year –- to comply with applicable maximum achievable control technology (MACT) standards in perpetuity, even when they reduced emissions below major-source thresholds.
