Phillips 66 Has Power Outage at Sweeny Plant, NRC Filing Shows

Phillips 66 (PSX) released an unknown amount of hydrogen sulfide, sulfur dioxide and benzene at its Sweeny, Texas, oil refinery because of flaring after a power outage, according to a filing with the U.S. National Response Center.

U.S. companies must notify the 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. Bloomberg News couldn’t immediately verify that the information in the NRC filing was accurate.
