## Abstract

The EPA is taking direct final action to approve revisions of the Texas State Implementation Plan (SIP). Specifically, EPA is approving revisions to regulations of the Texas Natural Resource Conservation Commission (TNRCC) which relate to definitions in Texas' general rules and to regulations relating to the permitting of new sources and modifications. The revisions that EPA is approving in this action are to recodify several provisions of the existing SIP without substantive changes and approve provisions for permit alterations which will strengthen the SIP as it pertains to the permitting of new and modified sources. Approval of these revisions will bring the federally approved SIP, which pertains to the permitting of new and modified sources more closely in line with the Texas' existing program. This action will better serve the State, the public, and the regulated community by making the approved SIP more closely match the rules that Texas currently implements. The approval of these revisions is independent of, and will not adversely affect, other SIP actions that EPA and TNRCC are currently undertaking to ensure the attainment and maintenance of air quality in the Dallas-Fort Worth, Houston-Galveston, and Beaumont-Port Arthur regions of Texas. Except where otherwise noted, EPA is approving revisions which Texas submitted in 1998 to the extent that they are equivalent to revisions that Texas previously submitted in 1993. Where noted, EPA is acting on provisions which Texas submitted in 1993. Finally, EPA is taking no action on certain provisions which relate to emissions reduction credits and offsets, permit exemptions, permit renewals, and emergency orders, which are not in the current SIP and for reasons discussed in the Supplementary Information.
