On July 26, black clouds rose from flares at a Chevron Phillips chemical plant in Baytown, Texas, after a power outage hit the plant and the surrounding area.
The company estimated in a preliminary report to the state that it released thousands of pounds of chemicals during the hours-long incident, including 17,500 pounds of carbon monoxide and 980 pounds and 280 pounds, respectively, of the carcinogens benzene and 1,3-butadiene.
