EPA is taking a direct final action to approve revisions to the applicable State Implementation Plan (SIP) for the State of Texas which relate to the Application Schedule regulations submitted to EPA on September 25, 2003 and January 24, 2008. The portions of the SIP revision approved today would revise and recodify existing SIP provisions addressing requirements related to the voiding of an application for a permit or permit amendment and implement the requirements of House Bill (HB) 3732, 80th Legislature (2007), and the Texas Health and Safety Code, section 382.0566, concerning specific deadlines for review and issuance of air permits for Advanced Clean Energy Projects (ACEP). EPA finds that these changes to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations, are consistent with EPA policies, and will improve air quality. This action is being taken under section 110 and parts C and D of the Act.
