Motiva Enterprises LLC said an unspecified amount of butadiene was released after an equipment failure at its Norco, Louisiana, refinery, according to a report to the National Response Center.
A furnace shutdown caused Motiva to “route heavy materials to the flare,” the report said. Butadiene is used to make synthetic rubber. The incident happened at 6 a.m. local time yesterday, according to the report.
Motiva is a refining and marketing joint venture of Saudi Refining Inc., a unit of Saudi Arabian Oil Co., and Shell Oil Co., a unit of Royal Dutch Shell Plc.
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.
The refinery, one of two that Motiva operates in southern Louisiana, has a capacity of 250,000 barrels a day, according to data compiled by Bloomberg.
