We invite you to comment on the draft wastewater permit for the City of Cologne's wastewater treatment facility.
The City of Cologne applied for a reissued water quality permit for the expansion of its wastewater treatment facility, which discharges to an unnamed reach before flowing into Benton Lake. The expansion is designed to increase the facility’s treatment capacity from 325,000 gallons per day to 463,000 gallons per day.
The draft wastewater permit includes more stringent limits for carbonaceous biochemical oxygen demand; new limits for ammonia nitrogen; and existing limits for total suspended solids, fecal coliform, and phosphorus. The draft permit also includes new monitoring requirements for chloride and sulfate.
The MPCA also proposes to modify the maximum load of pollutants from the proposed facility in the Lower Minnesota River Watershed total maximum daily load study and the Carver County bacterial total maximum daily load study, approved by the EPA in 2020 and 2007, respectively. The modifications reflect the facility’s discharge increase and will not contribute to impairments for any downstream waters.
Water quality permits - or National Pollutant Discharge Elimination System (NPDES) permits - establish specific limits and requirements to protect Minnesota's surface and groundwater quality. 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. Permits are enforced through a combination of self-reporting and compliance monitoring.
