We invite you to comment on the draft wastewater permit for the Tri-City Wastewater Treatment System's wastewater treatment facility.
The Tri-City Wastewater Treatment Systems Board has applied for a reissued water quality permit for its municipal wastewater treatment facility, which treats wastewater from the communities of Wells, Easton, and Minnesota Lake. The facility is designed to treat 1.08 million gallons per day and discharges to Faribault County Ditch 87, which flows into the Maple River.
The draft wastewater permit includes new limits for mercury and chloride. The board has applied for a chloride variance because it cannot feasibly reduce chloride from wastewater to meet state water quality limits due to the cost of treatment. The variance still requires the facility to meet interim chloride limits, complete chloride source investigation and minimization, and meet final limits within 15 years of variance approval. The permit also includes a schedule for the facility to meet the mercury limits, which will provide the facility time to plan and make required changes to meet the limits.
You can learn more and ask questions at an online public meeting on May 21, 2024, from 6-7 p.m. The meeting will be recorded and available upon request.
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.
