Approval and Promulgation of Implementation Plans; New Mexico; New Source Review (NSR) Preconstruction Permitting Program; Clarification of EPA's Approval of the Sunland Park Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard

EPA is taking final action to approve revisions to the applicable New Source Review (NSR) State Implementation Plan (SIP) for New Mexico. Among the changes, EPA is approving the following: the establishment of a new Minor NSR (MNSR) general construction permitting program; changes to the MNSR Public Participation requirements; the establishment of three different types of MNSR Permit Revisions; and the addition of exemptions for de minimis emission sources and activities from obtaining a MNSR permit. EPA finds that these revisions to the New Mexico SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations and are consistent with EPA policies. EPA also is providing clarification of an earlier separate EPA rulemaking action approving the Section 110(a)(1) Maintenance Plan for the 1997 8-hour ozone standard for the Sunland Park 1997 8-hour attainment area. This action is being taken under section 110 of the Act.
