The Environmental Protection Agency is approving revisions to the New Mexico State Implementation Plan (SIP) concerning the State transportation conformity rules. On November 2, 2006, the State of New Mexico submitted revisions to the New Mexico Administrative Code (NMAC) 20.2.99 to ensure consistency with amendments to the Federal Transportation Conformity Rule. On June 27, 2007, and May 13, 2009, the State submitted further revisions to NMAC 20.2.99 for consistency with subsequent Federal rule revisions. These plan revisions meet statutory and regulatory requirements, and are consistent with EPA's guidance.
