The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets limits on pollutant discharges to protect water quality.

The plant discharges into a tributary of the Salt River, which flows into the Mississippi River. The Mississippi River basin is a major ecological corridor, supporting diverse fish and bird species. The plant's secondary treatment helps reduce nutrient loads, which is important for preventing downstream hypoxia in the Gulf of Mexico.
