Approval and Promulgation of Implementation Plans; Texas; Water Heaters, Small Boilers, and Process Heaters; Agreed Orders; Major Stationary Sources of Nitrogen Oxides in the Beaumont/Port Arthur Ozone Nonattainment Area

The EPA is taking direct final action on revisions to the Texas State Implementation Plan (SIP). This rulemaking covers four separate actions. First, we are approving revisions to the Nitrogen Oxides ( NO<INF>X</INF>) SIP to add a rule for water heaters, small boilers, and process heaters sold and installed in Texas (the Texas Water Heater Rule). This rule will contribute to attainment of the 1- hour ozone standard in the Beaumont/Port Arthur (B/PA), Houston/ Galveston (H/GA), and Dallas/Fort Worth (D/FW) nonattainment areas and will contribute to continued maintenance of the standard in the rest of the State of Texas. Second, we are approving revisions to the Texas NO<INF>X</INF> SIP for certain major stationary point source categories in the B/PA ozone nonattainment area. These new limits for certain stationary point sources will contribute to attainment of the 1-hour ozone standard in the B/PA area. Third, we are approving revisions to the existing approved Texas NO<INF>X</INF> Reasonably Available Control Technology (RACT) SIP because the changes are administrative in nature. Fourth, we are approving two Agreed Orders between the State of Texas and two companies in Northeast Texas. These Orders will contribute to attainment of the 1-hour ozone standard in the B/PA, H/GA, and D/FW nonattainment areas and will contribute to continued maintenance of the standard in the eastern half of the State of Texas. The EPA is approving these SIP revisions to regulate emissions of NO<INF>X</INF> as meeting the requirements of the Federal Clean Air Act (the Act).
