4 chemical companies agree to clean Bayou d'Inde
LAKE CHARLES - The state Department of Environmental Quality says four petrochemical companies have agreed to clean pollution from more than 700 acres of Bayou d'Inde in southwest Louisiana.
Administrator Tom Harris says CITGO Petroleum Corp., PPG Industries, Axiall Corp. and Occidental Petroleum Corp. agreed to what is expected to be a yearlong project.
The American Press reports that in 2001, the U.S Environmental Protection Agency found dioxins in the lower bayou and polychlorinated biphenyls in its upper regions. Investigators also found heavy metals such as mercury, zinc, lead and chromium.
Harris says two companies dispute the department's finding that they were responsible for some of the pollution and won't participate.
He says state law lets companies that work with the government sue other companies believed to be responsible.
