Mosaic Crop Nutrition (Pine Bend warehouse) - Wastewater Permit

We invite you to comment on the draft wastewater permit for Mosaic Crop Nutrition's Pine Bend warehouse in Rosemount. 


Mosaic Crop Nutrition’s facility in Rosemount stores and distributes agricultural fertilizers. To keep its loading docks accessible, Mosaic routinely dredges the barge channel to the Mississippi River.


Mosaic’s dredging activity will generate a maximum of 27,000 cubic yards of material, which Mosaic will stockpile and de-water adjacent to the warehouse dock. Water will infiltrate into the groundwater, with berms with stable exterior slopes preventing water from discharging back into the Mississippi River. Once de-watering is complete, Mosaic will either reuse the dredged material on-site or transfer it to an off-site location.


This permit does not authorize or otherwise regulate dredging activity.  


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.
