In this direct final action, the EPA is approving the Texas State Implementation Plan(SIP) for the Houston/Galveston Ozone Nonattainment Area (HGA) Vehicle Miles Traveled (VMT) Offset Plan as 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. This action replaces the October 21, 1997 proposed disapproval of the HGA VMT Offset SIP revision previously submitted on August 16, 1994. This action is being taken under sections 110 and 182 of the Federal Clean Air Act, as amended (the Act).
