## Abstract

EPA is taking direct final action approving revisions to the Texas State Implementation Plan (SIP). The submitted revisions include a maintenance plan for Victoria County, Texas, developed to ensure continued attainment of the 1997 8-hour National Ambient Air Quality Standard (NAAQS or standard). The Maintenance Plan meets the requirements of Section 110(a)(1) of the Federal Clean Air Act (CAA or Act), EPA's rules, and is consistent with EPA's guidance. On March 12, 2008, EPA issued a revised ozone standard. Today's action is being taken to address requirements under the 1997 ozone standard. EPA is approving the revision pursuant to section 110 of the CAA.
