The Texas Commission on Environmental Quality has approved proposal of the Bexar County 2015 Eight-Hour Ozone Nonattainment Area Federal Clean Air Act, §179B Demonstration SIP Revision (Non-Rule Project No. 2019-106-SIP-NR). The proposed SIP revision would demonstrate that the Bexar County marginal ozone nonattainment area would attain the 2015 eight-hour ozone National Ambient Air Quality Standard by its attainment deadline “but for” anthropogenic emissions emanating from outside the United States. The public comment period will open on January 17, 2020 and close on February 19, 2020. A public hearing on the proposed SIP revision will be held on February 18, 2020 at 2:00 p.m. at the Alamo Area Council of Governments, 8700 Tesoro Drive, San Antonio.
