A boiler leak caused about 30 to 40 gallons of antifreeze to spill Monday evening at Maurices, 105 W. Superior St. in downtown Duluth.
The leak was reported shortly after 9 p.m. Initially, officials believed that as much as 300 gallons had leaked from the boiler. Duluth firefighters were able to capture some of the antifreeze with absorbents, but about 10 gallons ran into the city's storm sewer system.
Maurices hired Environmental Troubleshooters to finish the cleanup, said Ann Perry Moore, public information officer with the Minnesota Pollution Control Agency. They found no evidence that any antifreeze reached Lake Superior. Five gallons were found in a storm sewer sump. A city vacuum truck was used to recover it.
"Environmental Troubleshooters also helped with the cleanup in the building," Moore said. "No further impacts are expected, but Environmental Troubleshooters will keep an eye on that affected storm sewer through the next rain event to make sure nothing shows up."
