Mile 126.0 - LBD - Bayou Trepagnier
126 LBD - Bayou Trepagnier
Bayou Trepagnier runs from the petrochemical complex next to Norco through the LaBranch wetlands and into Bayou LaBranch just before it enters Lake Pontchartrain. The Shell oil refinery (now Motiva) dumped wastewater into the bayou for approximately 80 years from the 1930's to 1995. The contamination is extensive enough that a 5,500 foot stretch of the bayou starting at the petrochemical complex had to be completely filled in with clay and soil in an attempt to stabilize and lock the contamination in place.
