The Texas Commission on Environmental Quality has confirmed that the Dupont refinery located on Twin City Highway reported a chemical leak this morning (Nov. 3) at 10:25, indicating that 1,000 pounds of aniline were released, but that the leak has since been stopped and that section of the plant has been both evacuated and shut down, according to Heather Feldman, executive director for the Beaumont branch of the TCEQ.
