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

The 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), and Oxides of Nitrogen (NO<INF>X</INF>) in the HGB Area. We are also finalizing our proposal to approve the 2007 Voluntary Mobile Emission Reduction Program (VMEP) commitments for the HGB Area. This action is in accordance with section 110 of the federal Clean Air Act (the Act, CAA).
