Shell Oil Company dumped toxic chemicals into waterway for over 60 yrs

A Shell Oil Co. refinery dumped wastewater into the bayou for more than 60 years, lacing the mucky bottom with toxic chemicals and heavy metals.

DEQ says Bayou Trepagnier, one of state’s most polluted waterways, has been cleaned up

NORCO, La. — The state Department of Environmental Quality says one of Louisiana‘s most polluted waterways has been cleaned up. It’s Bayou Trepagnier (trep-AN’-yay) in Norco.

A Shell Oil Co. refinery dumped wastewater into the bayou for more than 60 years, lacing the mucky bottom with toxic chemicals and heavy metals.

The current owner, Motiva Enterprises LLC, agreed in 2008 to a $10 million cleanup plan.

DEQ says contaminated soil at the end nearest the refinery was removed as an 800-foot-wide “clean zone.”

It says that for another 6,000 feet of the bayou, sediments were solidified and stabilized, then capped with heavy clay. DEQ says about 43,000 yards of clay were used for that and to build access roads.

The bayou is a state scenic waterway.
