St. Charles officials lift storm sewer warning, investigation underway in St. John Parish to determine cause _lowres


Update, Saturday 11:06 a.m.:

An investigation is underway in St. John Parish to determine what led to a Friday-night discovery of a "hydrocarbon" in the storm-drain system. As a result, parish officials asked certain Luling residents -- those living on Courville Drive and in the 800 block of Collier Drive -- to stay indoors until the issue was resolved.

The shelter-in-place request was lifted around 11 p.m. on Friday.

Parish officials suspect that someone dumped gasoline or another hydrocarbon pollutant into that area, said St. John Parish spokesman Tristan Babin. On Friday, he said, Luling's fire department and the St. Charles Parish Oil Spill Coordinator responded to the scene, along with technical consultants from the Louisiana State Police and Louisiana Department of Environment Quality. After an on-scene assessment, the fire department flushed the pollutant from the system.

Update 11:15 p.m.:

The shelter-in-place has been lifted for area residents, according to a press release.

An investigation has revealed that hydrocarbon (possible gasoline) was introduced into the storm drainage system by unknown persons and St. Charles Parish officials will continue to monitor the system.
