Approval and Promulgation of Implementation Plans; State of New Mexico/Albuquerque-Bernalillo County; Infrastructure and Interstate Transport SIP 2010 Nitrogen Dioxide National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) submission from the Governor of New Mexico for the City of Albuquerque-Bernalillo County for the 2010 Nitrogen Dioxide (NO2) National Ambient Air Quality Standards (NAAQS). The submittal addresses how the existing SIP provides for implementation, maintenance, and enforcement of the 2010 NO2 NAAQS (infrastructure SIP or i-SIP). This i-SIP ensures that the State's SIP for Albuquerque-Bernalillo County is adequate to meet the state's responsibilities under the Federal Clean Air Act (CAA or Act), including the four CAA requirements for interstate transport of NO2 emissions.
