Exxon said there were no injuries reported and air quality monitoring indicated no immediate threat to the public from an oil spill discovered last weekend.
The company said oil was discovered hear a "remote rural property" near Torbert, La. The company said the 22-inch North Line pipeline carries crude oil to northern Louisiana. It was closed following the spill discovery.
"Our crews will be on location until the cleanup has been completed," Karen Tyrone, southern operations manager for Exxon, said in a statement. "Fortunately the oil was contained in the immediate area which will enhance our recovery efforts."
Exxon said a loss of pressure was reported from the pipeline Saturday. Crews were on scene, the company said, with vacuum trucks to recover the oil.
