City of Lonsdale Wastewater Treatment Facility - Wastewater Permit & Chloride Variance
We invite you to comment on the draft wastewater permit and chloride variance for the Lonsdale's wastewater treatment facility.
The City of Lonsdale applied for a reissued water quality permit for its wastewater treatment facility, which discharges to an unnamed ditch that flows into Union Lake. The facility is designed to treat 687,000 gallons per day.
The draft wastewater permit includes updated sampling frequencies for nitrogen, dissolved oxygen, and salty discharge parameters including bicarbonates, total calcium, and total potassium. The permit also includes new limits for chloride to protect aquatic life and recreation. The facility has applied for a variance from the chloride water quality standard because the facility is not currently designed to treat wastewater to meet the proposed final chloride limits. The variance still requires the facility to investigate and minimize chloride sources and meet the proposed final chloride limits within 15 years after the permit is issued.
For the chloride water quality variance, as required by Minn. R. 7050.0190, subp. 6, the Commissioner has scheduled an online public meeting for April 25, 2024, starting at 5:30 p.m. and ending after the presentation and questions (approximately 45 – 60 minutes). 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.
