## Abstract

The EPA is approving revisions to the Texas State Implementation Plan (SIP) Post-1999 Rate of Progress (ROP) Plan, the 1990 Base Year Inventory, and the Motor Vehicle Emissions Budgets (MVEB) established by the ROP Plan, for the Houston Galveston (HGA) ozone nonattainment Area submitted November 16, 2004. The intended effect of this action is to approve revisions submitted by the State of Texas to satisfy the reasonable further progress requirements for 1- hour ozone nonattainment areas classified as severe and demonstrate further progress in reducing ozone precursors. We are approving these revisions in accordance with the requirements of the Federal Clean Air Act (the Act).
