This action approves the State Implementation Plan (SIP) revisions for Board composition and conflict of interest disclosure requirements submitted both by the State of New Mexico and by Albuquerque/Bernalillo County, NM. The SIP revisions were submitted by the County and the State to satisfy the Federal mandate, found in section 128 of the Federal Clean Air Act (the Act), and in response to a SIP call letter to the Governor of New Mexico dated July 19, 1989, requiring a cure to identified SIP deficiencies concerning State Boards. The revisions were submitted by the Governor to EPA on April 20 and July 16, 1990, for the State portion, and on November 16, 1990, for the Albuquerque/Bernalillo County portion. Supplemental information was submitted for Albuquerque/Bernalillo County on December 18, 1990, October 21, 1991, and November 22, 1991. These revisions correct deficiencies for the New Mexico Environmental Improvement Board (NMEIB) and the Albuquerque/Bernalillo County Air Quality Board in order to comply with section 128 of the Act. The EPA approval of these New Mexico SIP revisions make the revisions federally enforceable. Subsequent correspondence in February and March 1993 addressed eligibility for ``public interest'' Board member positions.
