## Abstract

EPA is approving amendments to the Ohio Administrative Code (OAC) relating to the consolidation of Ohio's Ambient Air Quality Standards (AAQS) into Ohio's State Implementation Plan (SIP) under the Clean Air Act. On April 8, 2009, and August 11, 2009, Ohio EPA adopted amendments to various rules in the OAC to consolidate the state's AAQS. On September 10, 2009, Ohio EPA requested from EPA approval of amendments to the OAC with the intent to consolidate Ohio's AAQS into a single rule to provide greater accessibility for the regulated community and to the citizens of Ohio. EPA is approving the request because the revisions clarify the state's rules and thus better serve the purpose of providing for meeting these standards.
