Texas Commission on Environmental Quality (TCEQ) Toxicology News

TCEQ is proposing to remove the area in Harris County near the Lynchburg Ferry from the Air Pollutant Watch List ("APWL"). The area was initially added to the APWL based on monitored levels of benzene and styrene. TCEQ removed benzene from the Lynchburg Ferry APWL in 2010, and is now proposing to remove styrene because the agency has determined that monitoring data shows that ambient styrene concentrations are no longer at levels of potential concern. TCEQ will hold a public meeting on the proposed action on August 19, 2013, and will accept public comment on the proposed delisting through August 23, 3013. Additional information about the proposal and these opportunities for public participation are available on TCEQ's website.

The TCEQ Toxicology Division is now accepting toxicity information for use in developing toxicity factors for diethanolamine, triethanolamine, and C7 and C12 alkanes. Data must be submitted to TCEQ by October 18, 2013. Information about TCEQ toxicity factor development and this opportunity to provide constituent-specific data is available on TCEQ's website.

During July 2013 TCEQ issued separate health effect reviews for 2012 ambient air network monitoring data for Austin, Dallas/Fort Worth, Houston and Midland. The agency issued 2012 monitoring data reviews in June for Beaumont, Harlingen, San Antonio and Tyler. All of these reviews are available on TCEQ's website.
