Exxon Mobil Corp. had an upset at its Baton Rouge, Louisiana, chemical plant, according to a filing made with the National Response Center.
An ongoing release of ethylene resulted from the system upset yesterday, the filing showed.
U.S. refineries must notify the 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 filing was accurate.
The plant receives feedstock from the adjacent 503,000-barrel-a-day Exxon refinery, according to the company website.
