## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the Commonwealth of Virginia's state implementation plan (SIP). The SIP revision includes revised Virginia regulations which incorporate compliance dates necessary for implementing planning requirements for the 2008 8-hour ozone national ambient air quality standard (NAAQS). Specifically, the SIP revision includes revised Virginia regulations which added notification and compliance dates for sources seeking case-by-case reasonably available control technology (RACT) determinations required under the 2008 8-hour ozone NAAQS. EPA is approving this revision to the Virginia SIP in accordance with the requirements of the Clean Air Act (CAA).
