The Environmental Protection Agency (EPA) is approving under the Clean Air Act (CAA), a revision to Ohio's State Implementation Plan (SIP), submitted by the Ohio Environmental Protection Agency (OEPA) on November 12, 2020, and supplemented on February 11, 2021. OEPA requested to remove the Ohio Administrative Code (OAC) Permit Fees rule provisions from the Ohio SIP because they no longer exist at the state level and have been superseded by the fee system in Ohio's Title V permitting program and the Ohio Revised Code (ORC). OEPA rescinded the permit fee rules at the state level in 2003. EPA proposed to approve this action on April 13, 2021, and received no comments.
