The Environmental Protection Agency (EPA) is proposing to approve elements of State Implementation Plan (SIP) submissions from the State of Texas for Ozone (O3) and Nitrogen Dioxide (NO2) National Ambient Air Quality Standards (NAAQS). These submittals address how the existing SIP provides for implementation, maintenance, and enforcement of the 2008 O3 and 2010 NO2 NAAQS (infrastructure SIPs or i-SIPs). These i-SIPs ensure that the State's SIP is adequate to meet the state's responsibilities under the Federal Clean Air Act (CAA).
