Owens Corning (Minneapolis) - Wastewater Permit
We invite you to comment on the draft wastewater permit for the Owens Corning plant in Minneapolis.
Owens Corning manufactures roofing shingles and asphalt at its facility in Minneapolis. This facility discharges non-contact cooling water and stormwater to Ryan Creek. The facility is designed to treat 86,400 gallons per day.
The draft water quality permit includes a new station to monitor stormwater runoff from the property. The draft permit includes new sampling for total residual chlorine, sulfate, phosphorus, and nitrogen at the facility’s existing monitoring station and annual sampling for 40 PFAS compounds at both the existing and new stations. The draft permit requires the facility to submit an annual report that identifies and evaluates sources of PFAS.
The MPCA also proposes to modify the maximum load of pollutants each discharger of waste is allowed to release into the south metro area of the Mississippi River. The maximum load of pollutants, approved by the EPA in 2016, was calculated using the wrong flow rate for this facility. The correction will not result in an impairment for total suspended solids.
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.
