The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) to protect water quality in the region.

The plant discharges into the Missouri River basin, a vast watershed that drains much of the northern Great Plains. The Missouri River supports a variety of fish species, including pallid sturgeon and paddlefish, and provides critical habitat for migratory birds. Downstream, the river flows into the Mississippi River and eventually the Gulf of Mexico, making local treatment practices important for regional water quality.
