The EPA is taking direct final action on a request to redesignate Grant County, New Mexico from nonattainment area to attainment for the sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). In conjunction with this action, EPA is also approving the maintenance plan, and its associated contingency measures plan for the Grant County nonattainment area, which were submitted to ensure that the attainment of SO<INF>2</INF> NAAQS will continue to be maintained. The redesignation request and maintenance and contingency measures plans were submitted as a revision to the New Mexico State Implementation Plan (SIP) by the New Mexico Environment Department (NMED) on February 21, 2003. We are approving these revisions in accordance with the requirements of the Federal Clean Air Act (Act).
