We invite you to comment on the draft industrial wastewater permit for the Andersen Corporation facility in Bayport.
The primary activity at the facility is the manufacturing of clad wood windows and patio doors. This draft permit authorizes the following discharges via five outfalls: 1) Non-contact cooling water from air compressor systems at a maximum rate of 842,000 gallons per day; 2) Non-contact cooling water from the solvent recovery system at a maximum rate of 576,000 gallons per day; 3) Reverse osmosis concentrate at a maximum rate of 10,000 gallons per day; and 4) Contaminated groundwater that has been treated by a granular activated carbon system at a maximum rate of 432,000 gallons per day.
The draft industrial wastewater permit includes the addition of monitoring for sulfate, total suspended solids (TSS), nitrite plus nitrate nitrogen, total Kjeldahl nitrogen, and total nitrogen. Requirements to submit a PFAS Screening Report and a piping integrity plan have also been added.
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. 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.
