In this final action, the EPA is approving, as part of the Texas State Implementation Plan(SIP) for the Houston/ Galveston Ozone Nonattainment Area (HGA), the Vehicle Miles Traveled (VMT) Offset Plan to offset any growth in emissions from growth in VMT, or number of vehicle trips in the Houston/ Galveston severe ozone nonattainment area. This is part of the State's effort to attain the National Ambient Air Quality Standard (NAAQS) for ozone. The State demonstrated that emissions from increases in VMT or numbers of vehicle trips within HGA will not rise above an established ceiling by 2007; thereby not requiring additional transportation control measure (TCM) offsets to prevent an increase in VMT above the ceiling. The requirements for the VMT Offset plan to be consistent with the State's demonstration of Reasonable Further Progress (RFP) and attainment are addressed in a corresponding action for the HGA area taken and published separately in this Federal Register. This action approves the proposed approval published on July 10, 2001 (66 FR 35920). Comments made on the direct final rule, published on July 10, 2001 (66 FR 35903) and withdrawn on September 4, 2001 (66 FR 46220), are addressed later in this action. This action is being taken under sections 110 and 182 of the Federal Clean Air Act, as amended (the Act, or CAA).
