Cottage Grove chemical plant to pay $480,500 for EPA violations

Hydrite Chemical Co. exceeded its hazardous air pollution permit limits and has agreed to pay a $480,500 fine for violations at a plant in Cottage Grove, according to a Wisconsin State Journal report.

The EPA alleges that in 2017 and 2019 the plant at 114 N. Main St. failed to monitor and replace carbon filters and keep tanks closed, and failed to account for “fugitive emissions” from equipment leaks as required by its permit. The lack of oversight caused Hydrite to exceed its annual limit of 25 tons of hazardous pollutants, including volatile organic compounds.
