On Thursday evening April 25, we inadvertently overfilled a fire-fighting foam tank on our Stanton Street facility, releasing approximately 25 gallons of foam outside our containment system. Of that, we estimate that less than half reached a stormwater basin that leads to the sewer and the Menominee River. We immediately plugged the stormwater basin and did not observe any foam in the river. We also pumped and cleaned material and structures outside our containment system and we will be performing additional restoration activities as necessary. The tank overflow was stopped right away and no further foam has been released. We immediately notified the Wisconsin Department of Natural Resources and are working with them to complete any necessary formal reporting and further cleanup and containment measures.
