MINNEAPOLIS (WCCO) — A Twin Cities plant that released a toxic chemical into the air for years has completed testing of its new pollution control equipment.

A third party tested Water Gremlin’s equipment on Tuesday to measure its effectiveness. We told you last week the company in White Bear Township missed its deadline as outlined in a stipulation agreement with the state.

After being given two extensions, the Minnesota Pollution Control Agency said it would fine the company $500 a day until the testing was done. That total fine will be $5,500.

The results will be sent to the MPCA and should be available next week. Then, next steps will be determined.
