Approval and Promulgation of Air Quality Implementation Plans; New Mexico; Section 110(a)(2) Infrastructure Requirements for 1997 8-Hour Ozone and Fine Particulate Matter National Ambient Air Quality Standards

EPA is approving submittals from the State of New Mexico pursuant to the Clean Air Act (CAA or Act) that address the infrastructure elements specified in the CAA section 110(a)(2), necessary to implement, maintain, and enforce the 1997 8-hour ozone and 1997 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standards). We are determining that the current New Mexico State Implementation Plan (SIP) meets the following infrastructure elements which were subject to EPA's completeness findings pursuant to CAA section 110(k)(1) for the 1997 8-hour ozone NAAQS dated March 27, 2008, and the 1997 PM<INF>2.5</INF> NAAQS dated October 22, 2008: 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). EPA is also approving a November 2, 2006, SIP revision to regulation 20.2.3 of the New Mexico Administrative Code (NMAC) (Ambient Air Quality Standards), to remove the state ambient air quality standards from being an applicable requirement under the State's Title V permitting program, found at 20.2.70 NMAC (Operating Permits). EPA is also converting our February 27, 1987, conditional approval of New Mexico's PSD program (52 FR 5964) to a full approval based on the November 2, 1988, approval of New Mexico's stack height regulations (53 FR 44191). Lastly, EPA is making a number of U.S. Code of Federal Regulations (CFR) codification technical corrections to amend the description of the approved New Mexico SIP. This action is being taken under section 110 and part C of the Act.
