Approval and Promulgation of Air Quality Implementation Plans; New Mexico; Albuquerque/Bernalillo County; Prevention of Significant Deterioration (PSD) and New Source Review

The EPA is approving revisions to the State Implementation Plan (SIP) for the Albuquerque/Bernalillo County, New Mexico, area that were adopted on December 14, 2005, and submitted to EPA by the Governor of New Mexico on May 24, 2006. The SIP revisions modify the PSD and Nonattainment New Source Review (NNSR) regulations in the SIP. They were submitted to make the area's PSD and NNSR rules consistent with the Federal PSD and NNSR revised regulations, which were promulgated by EPA on December 31, 2002, (67 FR 80186), and reconsidered with minor changes on November 7, 2003, (68 FR 63021), (collectively, the "2002 New Source Review (NSR) Reform rules"). The revisions include provisions for baseline emissions calculations, an actual-to-projected- actual methodology for calculating emissions changes, options for plantwide applicability limits, and recordkeeping and reporting requirements. The EPA is approving these revisions pursuant to section 110, part C, and part D of the Federal Clean Air Act.
