Approval and Promulgation of Air Quality Implementation Plans; Texas; Revisions to Emissions Inventory Reporting Requirements and Conformity of General Federal Actions, Including Revisions Allowing Electronic Reporting Consistent With the Cross Media Electronic Reporting Rule

EPA is approving Texas State Implementation Plan (SIP) revisions that were submitted by the Governor of Texas and by the Texas Commission on Environmental Quality (TCEQ) respectively on December 17, 1999 and February 26, 2007. The revisions pertain to regulations on reporting air pollution emissions (emission inventories), and conformity of general federal actions to SIPs. The revisions on emissions inventories allow the state to collect additional data related to emissions from stationary sources and contain requirements for sources in regions that are in violation of a national ambient air quality standard (NAAQS) to report typical daily emissions of carbon monoxide and ozone precursor gases during the winter and summer months, respectively. The revisions also allow for electronic reporting of documents required under federally authorized programs and designated state programs, including emissions inventories from stationary sources. The revisions to regulations on conformity of general federal actions to SIPs are non-substantive. EPA is approving the revisions pursuant to Section 110, part D of the Federal Clean Air Act (CAA).
