Approval and Promulgation of Air Quality Implementation Plans; Louisiana; 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 Louisiana 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 Louisiana 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 SIP revisions that modify Louisiana's Prevention of Significant Deterioration (PSD) SIP for the 1997 8-hour ozone NAAQS to include nitrogen oxides (NO<INF>X</INF>) as an ozone precursor. This action is being taken under section 110 and part C of the Act.
