McLaughlin Gormley King (Chaska) - Wastewater Permit
We invite you to comment on the draft wastewater permit for McLaughlin Gormley King Co in Chaska.
McLaughlin Gormley King manufactures special chemicals, primarily insecticides, in Chaska. The production process uses non-contact cooling water. The facility discharges wastewater and stormwater from a pond that flows to a wetland and eventually to Hazeltine Lake.
Along with current limit and monitoring requirements, the draft water quality permit adds limits for total zinc and monitoring for per- and polyfluoroalkyl substances (PFAS), hardness in the wetland, and salty discharge monitoring.
Wastewater from industrial and commercial sources may contain pollutants at levels that could adversely affect the water quality in area wetlands, streams, rivers, and lakes. Water quality permits - or National Pollutant Discharge Elimination System (NPDES) permits - establish specific limits and requirements to protect Minnesota's surface and groundwater quality. All wastewater must be treated before it goes into surface water to protect human health and aquatic life. Permits are regularly reviewed and updated as they expire, allowing the MPCA to incorporate new information about the impacts of pollutants on the environment in future permits.
