Approval and Promulgation of Implementation Plans; Texas; Reasonably Available Control Technology for Major Stationary Sources of Nitrogen Oxides in the Houston/Galveston, Beaumont/Port Arthur, and Dallas/Fort Worth Ozone Nonattainment Areas

The EPA is taking direct final action on revisions to the Texas State Implementation Plan (SIP). This rulemaking covers three separate actions: Converting EPA's conditional approval of the Texas Nitrogen Oxides (NO<INF>X</INF>) rules for the Houston/Galveston (H/GA) and Beaumont/Port Arthur (B/PA) ozone nonattainment areas to a full approval as Reasonably Available Control Technology (RACT); approving as RACT, revisions to the NO<INF>X</INF> rules for lean burn, stationary, reciprocating internal combustion engines in the B/PA, H/ GA, and Dallas/Fort Worth (D/FW) ozone nonattainment areas; and approving revisions to the NO<INF>X</INF> rules for major stationary sources in the D/FW ozone nonattainment area, as meeting RACT. The EPA is approving these SIP revisions to regulate emissions of NO<INF>X</INF> as meeting the NO<INF>X</INF> RACT requirements of the Federal Clean Air Act (the Act).
