The EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Texas establishing a low-Reid Vapor Pressure (RVP) fuel requirement for gasoline distributed in 95 counties in the eastern and central parts of Texas. Texas developed this fuel requirement to reduce emissions of volatile organic compounds (VOCs) as part of the State's strategy to achieve the National Ambient Air Quality Standard (NAAQS) for ozone in the Houston-Galveston and Dallas- Fort Worth nonattainment areas. We are approving Texas' fuel requirement into the SIP because we found that the fuel requirement is in accordance with the requirements of the Clean Air Act (the Act) as amended in 1990 and is necessary for these nonattainment areas to achieve the ozone NAAQS.
