Exxon reports flares at Joliet refinery

Exxon Mobil Corp., the world’s largest publicly traded oil company, flared gases at its Joliet refinery in Illinois, according to a filing with regulators.

The flaring took place at 2:24 p.m. local time Wednesday, Irving, Texas-based Exxon said in the statement to the Illinois Emergency Management Agency. The report didn’t say what caused the release.

A filing with the National Response Center said a release of gases occurred at the plant, without giving details. 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.
