Case summary

On September 27, 2019, EPA Region 6 issued an Administrative Compliance Order on Consent (AOC) under the authority of Section 113(a)(1)(A) of the Clean Air Act, 42 U.S.C. ? 7413(a)(1)(A) to Union Carbide Corporation (Union Carbide) for its St. Charles Operations Site located in Hahnville, LA.
