Marathon Has Hydrofluoric Acid Release at Texas City Refinery

Marathon Oil Corp. (MRO) released hydrofluoric acid and hydrocarbons at its Texas City refinery in Texas and yesterday, according to a filing with the National Response Center.

A release of isobutene, butane, propane and hydrofluoric acid from a depropanizer tower was reported in a filing made with the center yesterday. The incident occurred at 4 p.m. local time, according to the report.

“The source of the small release at Marathon’s Texas City refinery has been located and our crews have isolated it,” Shane Pochard, a company spokesman who is based in Findlay, Ohio, said in an e-mail today. Pochard declined to specify the source and reason for the release.

A shelter-in-place warning was issued by the Texas City’s emergency management office yesterday. The advisory was lifted at 6 p.m. after the city didn’t detect any hydrofluoric acid in the air.

U.S. refineries must notify the National Response Center if they release hazardous substances in excess of reportable quantities, according to the Comprehensive Environmental Response, Compensation and Liability Act, commonly known as Superfund.

Marathon’s Texas City refinery has a capacity of 81,500 barrels a day, according to data compiled by Bloomberg.
