The plant discharges into the Mississippi River, which flows south to the Gulf of Mexico. This river is a critical habitat for fish, migratory birds, and other wildlife. The Mississippi River basin is ecologically sensitive due to nutrient pollution that contributes to the Gulf of Mexico hypoxic zone. Secondary treatment at this plant helps mitigate local nutrient inputs.
