LEMONT, Ill. (AP) — Officials are monitoring air quality near a suburban Chicago oil refinery after a fire lit up the evening sky.
Authorities say the blaze at the Citgo oil refinery in Lemont has been extinguished. No one was injured and authorities say no nearby homes were evacuated.
Citgo spokesman Pete Colarelli said in a statement that Wednesday’s fire began shortly after 7:30 p.m. in the refinery’s crude oil unit, sending thick smoke billowing into the sky. The blaze was brought under control shortly after 10 p.m.
The cause of the fire remains under investigation. But Lemont Mayor Brian Reaves told the Chicago Sun-Times that “something sparked.”
The massive refinery that’s about 20 miles southwest of Chicago expands into unincorporated sections of Will County and Romeoville.
