Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Virginia; Oxygenated Gasoline Program

EPA is taking direct final action on a revision to the Commonwealth of Virginia State Implementation Plan (SIP). The revision makes the oxygenated gasoline program a contingency measure of the maintenance plan for the Northern Virginia area, which means that the oxygenated gasoline program would only be required to be implemented in the Northern Virginia area if there is a violation of the carbon monoxide (CO) national ambient air quality standard (NAAQS). EPA is approving this revision in accordance with the requirements of the Clean Air Act.
