Summary

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), a revision to Ohio's State Implementation Plan (SIP), submitted by the Ohio Environmental Protection Agency (OEPA) on March 30, 2011 and amended on August 22, 2019. The proposed SIP revision modifies Ohio's Prevention of Significant Deterioration (PSD) program to establish emission thresholds for determining when stationary source projects are potentially subject to Ohio's PSD permitting requirements for greenhouse gas (GHG) emissions. Consistent with Ohio's August 22, 2019, request, EPA is not acting on the portion of Ohio's submittal that would allow for automatic rescission of certain rule provisions and permit terms and conditions if certain triggering events occurred (i.e., the auto-rescission clause).
