U.S. Bank Stadium - Wastewater Permit
We invite you to comment on the draft wastewater permit for U.S. Bank Stadium.
U.S. Bank Stadium is an entertainment, sports, and event venue located in Minneapolis. The facility was constructed on a property with historical uses that included bulk fuel storage, gas stations, railroad tracks, printing facilities, machine shops, freight depots, auto body and repair shops, manufacturing facilities, and junk yards. Because of the historical land uses in the vicinity of the facility, the groundwater beneath the facility is contaminated with chlorinated volatile organic compounds and petroleum products.
To protect the lowest levels of the stadium from flooding, the facility directs groundwater through a tile system to four basement sumps, then pumps each sump to a stormwater collection system that loops around the facility.
The system discharges the collected sump water and stormwater mixture to the city storm sewer, which discharges to the Mississippi River at 11th Avenue. The facility discharges contaminated groundwater from the pumped sumps at an average rate of 480,000 gallons per day and maximum rate of 1.7 million gallons per day. The facility can discharge combined sump water and stormwater at a maximum rate of 3.3 million gallons per day.
The draft industrial wastewater permit adds limits for total suspended solids to protect receiving water quality. The draft permit also adds monitoring requirements for total sulfate and total dissolved solids. The draft permit removes monitoring requirements for total chloride and specific conductance.
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.
