Approval and Promulgation of Air Quality Plans, Texas and Louisiana; Revision to the Texas and Louisiana State Implementation Plans Regarding Negative Declarations for Source Categories Subject to Reasonably Available Control Technology

Riepilogo

Section 172(c)(1) of the Clean Air Act (the Act) requires nonattainment areas to reduce emissions from existing sources by adopting, at a minimum, reasonably available control technology (RACT). The EPA has established 13 source categories for which RACT must be implemented and issued associated Control Technique Guidelines (CTGs) or Alternate Control Techniques (ACTs) documents. If no major sources of volatile organic compound (VOC) emissions in a particular source category exist in a nonattainment area, a State may submit a negative declaration for that category. Louisiana has submitted negative declarations for certain source categories in the Baton Rouge ozone nonattainment area. Texas has submitted negative declarations for certain source categories in the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston ozone nonattainment areas. The EPA is approving these negative declarations for Louisiana and Texas.
