5 EYEWITNESS INVESTIGATION: Who is Checking Safety Plans for Toxic Chemical Stored at Oil Refineries?

September 26, 2018 07:19 PM

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.
