Approval and Promulgation of Implementation Plans; New Mexico; Albuquerque/Bernalillo County: Infrastructure and Interstate Transport Requirements for the 1997 and 2008 Ozone and the 1997 and 2006 PM2.5 NAAQS

EPA is approving submittals from the Governor of New Mexico for the City of Albuquerque/Bernalillo County area, pursuant to the Clean Air Act (CAA or the Act). These submittals address the infrastructure elements specified in the CAA necessary to implement, maintain, and enforce the 1997 and 2008 8-hour ozone and the 1997 and 2006 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standards). We find that the current Albuquerque/Bernalillo County State Implementation Plan (SIP) meets the infrastructure elements for the 1997 and 2008 8-hour ozone NAAQS and the 1997 and 2006 PM<INF>2.5</INF> NAAQS. We also find that the current Albuquerque/Bernalillo County SIP meets the CAA requirement that emissions from sources in the area do not interfere with prevention of significant deterioration (PSD) measures required in the SIP of any other state, with regard to the 1997 and 2008 ozone and 1997 and 2006 PM<INF>2.5</INF> NAAQS. EPA is also approving SIP revisions that modify the PSD SIP to include nitrogen oxides (NO<INF>X</INF>) as an ozone precursor. EPA is approving revisions to the Albuquerque/Bernalillo County PSD SIP that identify the PM<INF>2.5</INF> precursors and establish significant emission rates for said precursors, consistent with the federal requirements. We are also approving other revisions to the Albuquerque/Bernalillo County PSD SIP to maintain consistency with the federal PSD permitting requirements. In addition to these revisions, EPA is approving other revisions to the Albuquerque/ Bernalillo County SIP necessary to implement the NAAQS.
