Emergency authorities in Ascension Parish have lifted a shelter in place order around the Rubicon facility after the all-clear was given about 10:25 p.m. Thursday, parish sheriff’s deputies said.

Lt. Col. Bobby Webre, sheriff’s chief of criminal operations, said Rubicon plant had an air release of some kind sometime around 9:15 p.m. Thursday, initially forcing the shelter in place order for a one-mile radius around the plant.

Webre said authorities were concerned about the release with high winds in the area Thursday night. The chemical emergency was reduced to an alert after the air release had ended. Webre said no injuries are reported.

He said some workers in the plant itself could still be sheltering in place as of 10:30 p.m. Thursday

The one-mile radius did not appear to affect many homes but did include other plants and businesses and comes close to La. 30 near La. 73 and includes La. 73 between La. 30 and River Road.

The Rubicon plant is located at 9156 La. 75, Geismar, which is along River Road southwest of Gonzales and Interstate 10.

Hazardous materials deputies with the Sheriff’s Office were still at the plant late Thursday night assessing the situation.
