When the Husky Energy refinery went up in flames in Superior, Wis. last spring, the town mayor said it had the potential to be "absolutely catastrophic" because of a highly toxic and dangerous chemical that was stored there.
That chemical is called hydrogen fluoride. It's used by oil refineries to improve the quality of gasoline and it's also stored at an oil refinery in St. Paul Park – here in the Twin Cities metro. It is supposed to be highly regulated by the Environmental Protection Agency.
However, a 5 EYEWITNESS NEWS investigation has found the EPA has not inspected those refineries or reviewed its safety plans in years.
Our investigative team traveled to Superior; Chicago, Ill.; and northern California to talk to safety advocates, review EPA records and ask a chemical expert about the safety risks associated with hydrogen fluoride.
Tonight on 5 EYEWITNESS NEWS at 10 p.m., find out why the safety plans for such a dangerous chemical are not being reviewed by federal regulators.
