A White Bear Township manufacturer will pay more than $7 million in fines and environmental projects for emitting high levels of a toxic chemical into the air over many years.
Water Gremlin's settlement is the second-largest in the history of the Minnesota Pollution Control Agency (MPCA), topped only by the $8 million settlement in 1999 with Koch Petroleum Group over violations at its Rosemount refinery.
The excessive emissions from Water Gremlin went on for more than 15 years and reached a peak last year, as the company struggled with its pollution control equipment, according to the MPCA.
"Not only was this a permit violation, it put people's health at risk," MPCA Commissioner Laura Bishop told reporters Friday. "This should not have happened."
Bishop acknowledged that the penalty is a "small consolation" to concerned local residents.
Water Gremlin makes fishing sinkers and electrical contacts for batteries at its plant at 4400 Otter Lake Road. It used trichloroethylene, a widely used metal degreaser that is also a known carcinogen, to coat its battery leads to prevent corrosion.
Last summer the MPCA discovered the company was violating its air pollution permit. In January, it asked Water Gremlin to shut down part of its operation because it was emitting high levels of trichloroethylene into the air.
At times, the emissions nearest the plant were found to be as high as 100 times the state's health guidance value for trichloroethylene, which is 2 micrograms per cubic meter of air. The MPCA said it thinks the pollution was worst in 2018 but that excessive levels of the chemicals have been released as far back as 2002.
