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 finalizing its proposal to approve revisions to the Texas State Implementation Plan (SIP) for the Houston/Galveston/Brazoria (HGB) 1997 8-Hour ozone nonattainment Area (Area). The HGB Area consists of Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery and Waller counties. Specifically, we are finalizing our proposed approval of portions of two revisions to the Texas SIP submitted by the Texas Commission on Environmental Quality (TCEQ) as meeting certain Reasonably Available Control Technology (RACT) requirements for Volatile Organic Compounds (VOC) in the HGB Area. This action is in accordance with section 110 of the federal Clean Air Act (the Act, CAA).
