Approval and Promulgation of Implementation Plans; New Mexico/Albuquerque-Bernalillo County; Infrastructure and Interstate Transport State Implementation Plan for the 2010 Sulfur 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 Sulfur Dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). The submittal addresses how the existing SIP provides for implementation, maintenance, and enforcement of the 2010 SO<INF>2</INF> 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 SO<INF>2</INF> emissions.
