Chevron Phillips Chemical Co. released gases at its chemical plant in Port Arthur, Texas, according to a filing with the U.S. National Response Center.
The flaring of benzene, nitric oxide and nitrogen dioxide occurred at 3:40 p.m. local time yesterday, according to an incident report on the National Response Center website.
U.S. refineries and chemical plants must notify the National Response Center if they release hazardous substance in excess of reportable quantities, according to the Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as Superfund.
Bloomberg News could not immediately verify whether the information in the filing was accurate.
Chevron Phillips Chemical was preparing to restart an ethylene unit at the plant after planned maintenance, the Woodlands, Texas-based company said in a regulatory filing with the Texas Commission on Environmental Quality yesterday.
