The Environmental Protection Agency (EPA) is approving revisions to the Texas State Implementation Plan (SIP) that establish the public participation requirements for air quality permits. EPA finds that these revisions to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations and are consistent with EPA policies. Texas submitted the public participation provisions in four separate revisions to the SIP on July 22, 1998; October 25, 1999; July 2, 2010; and March 11, 2011. EPA is finalizing this action under section 110 and parts C and D of the Clean Air Act (the Act).
