Air Plan Approval; District of Columbia; Creation of Synthetic Minor Permit Program
Key claim: The EPA is approving the District of Columbia’s state implementation plan revision to create a federally enforceable synthetic minor permit program for sources of criteria pollutants under the Clean Air Act.
Abstract
(Rule · Environmental Protection Agency) The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Department of Energy and Environment (DOEE) on behalf of the District of Columbia (DC). The revision pertains to creating a synthetic minor permit program and resolving the regulatory differences between DC’s current regulations and those regulations approved previously in Chapters 1 and 2 of the Air Quality Regulations codified in title 20 of the District of Columbia Municipal Regulations (DCMR). The intended effect of this action is to enable DC to create federally enforceable synthetic minor permit conditions for sources of criteria pollutants. The EPA is approving these revisions to the DC SIP in accordance with the requirements of the Clean Air Act (CAA).
Why this matters
Synthetic minor permit programs let facilities voluntarily accept federally enforceable emission caps to avoid triggering major-source permitting (Title V, NSR/PSD), which reduces compliance costs while preserving air-quality protections. EPA’s approval gives DC’s program federal enforceability, aligning local permitting with Clean Air Act structure and clarifying the regulatory pathway for smaller emitters of criteria pollutants.
