Approval and Promulgation of Implementation Plans; Texas; Reasonably Available Control Technology in the Houston-Galveston-Brazoria Ozone Nonattainment Area

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing approval of revisions to the Texas State Implementation Plan (SIP) addressing volatile organic compounds (VOC) revised rules and the State's reasonably available control technology (RACT) analyses for VOC and nitrogen oxides (NOX). We are proposing to approve the revised VOC rules as assisting in reaching attainment of the 2008 ozone National Air Quality Ambient Air Quality Standards (NAAQS or the standard) and as meeting the RACT requirements in the Houston- Galveston-Brazoria 2008 8-hour ozone nonattainment area (HGB area). We are also proposing to approve negative declarations for certain VOC source categories subject to RACT in the HGB area. The EPA also is proposing to find that the State's RACT analyses demonstrate that the HGB area meets the VOC and NOX RACT requirements for this standard.
