Abstract
EPA is taking direct final action to approve a revision to the Commonwealth of Virginia State Implementation Plan (SIP). The revision adds the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million (ppm) and related reference conditions and updates the list of appendices under "Documents Incorporated by Reference." Virginia's SIP revision for the NAAQS for ozone is consistent with the 8-hour Federal standard. This action is being taken under the Clean Air Act (CAA).
