Approval and Promulgation of Air Quality Implementation Plans; State of New Mexico; Infrastructure SIP Requirements for the 2008 Ozone and 2010 Nitrogen Dioxide National Ambient Air Quality Standards; Interstate Transport of Fine Particulate Matter Air Pollution Affecting Visibility

The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of New Mexico addressing the applicable requirements of Clean Air Act (CAA) section 110 for the 2008 National Ambient Air Quality Standards (NAAQS) for Ozone (O3) and the 2010 NAAQS for Nitrogen Dioxide (NO2), both of which require that each state adopt and submit a SIP to support implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by EPA. These SIPs are commonly referred to as ``infrastructure'' SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. EPA is also proposing to find that the State of New Mexico meets the 2006 fine particulate matter (PM2.5) NAAQS requirement pertaining to interstate transport of air pollution and visibility protection.
