Approval and Promulgation of Implementation Plans; Texas; Reasonably Available Control Technology for the 1997 8-Hour Ozone National Ambient Air Quality Standard

The Environmental Protection Agency (EPA) is approving revisions to the Texas State Implementation Plan (SIP) as it applies to the volatile organic compound (VOC) sources in the offset lithographic printing source category. We are approving revisions to the regulations for this source category as they apply in the Dallas/Fort Worth (DFW), El Paso and Houston/Galveston/Brazoria (HGB) areas. These revisions are based on the recommendations for Reasonably Available Control Technology (RACT) in the Control Technique Guideline (CTG) issued in 2006 entitled, "Lithographic Printing Materials and Letterpress Printing Materials." We are also approving the corresponding RACT analysis for this category for both the HGB and DFW 1997 8-hour ozone nonattainment areas. The EPA is approving these revisions pursuant the federal Clean Air Act (the Act, CAA) and consistent with the EPA's guidance.
