Chevron Corp., the second-largest U.S. energy company, reported a benzene release after a pump failed at its Pascagoula, Mississippi, crude refinery.
The incident happened yesterday at 6:30 p.m. local time, according to the National Response Center.
U.S. refineries 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.
The Pascagoula refinery is San Ramon, California-based Chevron’s largest U.S. oil-processing plant.
Exxon Mobil Corp. of Irving, Texas is the biggest U.S. energy company by market value.
