Please join the Texas Commission on Environmental Quality (TCEQ) for a public hearing on the 179B demonstration State Implementation Plan (SIP) revision. The public hearing will be Tuesday, February 18, 2020, at 2:00 PM at the Alamo Area Council of Governments' Al J. Notzon III Board Room (8700 Tesoro Drive, Suite 100, San Antonio, TX 78217). The TCEQ will be holding a public Q&A session at 1:30 PM.
What is a 179B demonstration? The Federal Clean Air Act, §179B allows States “… to consider in their attainment plans and demonstrations whether an area might meet the ozone NAAQS by the attainment date ’but for’ emissions contributing to the area originating outside the U.S.” (80 FR 65444). If the EPA approves the 179B demonstration SIP Revision for Bexar County, it may avoid a reclassification to moderate event if it does not meet the ozone standard by the September 24, 2021 attainment date.
The TCEQ has made available the draft 179B demonstration SIP revision for Bexar County, which can be found here. The TCEQ presented preliminary findings from its 179B analysis at AACOG on September 26, 2019. A live stream of that presentation is available here.
