Air Plan Approval; Oklahoma; Updates to the State Implementation Plan for New Source Review Permitting and General SIP Provisions
What happened
The Environmental Protection Agency (EPA) approved parts of Oklahoma's revisions to its State Implementation Plan, specifically for the New Source Review (NSR) permit program. These revisions were submitted by the State of Oklahoma between 2002 and 2025. The final rule, signed by Donald Trump, becomes effective on August 3, 2026.
Why it matters
This approval means Oklahoma's chosen air permitting program updates are federally enforceable, impacting how the state manages air quality. The EPA states this action does not impose new federal requirements beyond state law, nor does it significantly burden small businesses.
