The EPA is approving the Texas 1-hour ozone attainment demonstration State Implementation Plan (SIP) for the Beaumont/Port Arthur (BPA) moderate ozone nonattainment area. The attainment demonstration SIP is addressed in the State of Texas submittals dated November 12, 1999 and April 25, 2000. In approving the attainment demonstration, EPA is: Extending the ozone attainment date for the BPA ozone nonattainment area to November 15, 2007 while retaining the area's current classification as a moderate ozone nonattainment area; approving the State's enforceable commitment to perform a mid-course review and submit a SIP revision to the EPA by May 1, 2004; finding that the BPA area meets the Reasonably Available Control Technology (RACT) requirements for major sources of volatile organic compounds (VOC) emissions; and approving the motor vehicle emissions budgets (MVEB). A notice of proposed rule making was published on this action on December 27, 2000 (65 FR 81786). EPA received comments on that proposal. EPA has also received comments on two related proposed actions: the "Extension of Attainment Dates for Downwind Transport Areas," 64 FR 12221 (March 25, 1999); and, the proposed rulemaking published on April 16, 1999 (64 FR 18864), which addressed the Clean Air Act reclassification or eligibility for extension of attainment date for the BPA area. In this action, EPA responds to the comments to all three of these documents. For details on the SIP submittals and the EPA analysis of the submittals, refer to the December 27, 2000 proposed rule.
