The EPA is finalizing approval of rules for the control of NO<INF>X</INF> emissions into the Texas State Implementation Plan (SIP). Texas submitted this SIP revision to us on May 30, 2007 (May 30, 2007 SIP revision), and we proposed approval of the May 30, 2007 SIP revision on July 11, 2008. The May 30, 2007 SIP revision to the Texas SIP is a substantive and non-substantive recodification and reformatting of the NO<INF>X</INF> rules currently approved in the Texas SIP, and also includes a part of the Nitrogen Oxides (NO<INF>X</INF> ) reductions needed for the Dallas/Forth Worth (D/FW) area to attain the Federal 8-hour ozone National Ambient Air Quality Standard (NAAQS). Today's final rulemaking covers four separate actions. First, we are approving the repeal, from the Texas SIP, of the current Chapter 117 rules that correspond to the re-codified new rules and the revised and reformatted rules because the reformatted revision will better accommodate future additions/revisions to the rules. Second, we are approving revisions to the Texas SIP that add new controls for the D/FW major NO<INF>X</INF> point sources. We are not, however, taking action on the Texas rules for cement plants in this document. We proposed approval of the rules for cement plants in a separate Federal Register document. Third, we are approving revisions to the Texas SIP that add new controls for D/FW minor NO<INF>X</INF> sources. Fourth, we are approving revisions to the Texas SIP that add new controls for combustion sources in East Texas. These NO<INF>X</INF> reductions will assist the D/FW area to attain the 8-hour ozone NAAQS. We are approving all of these actions as meeting the requirements of section 110 and part D of the Federal Clean Air Act (the Act).
