TRACY STP Wastewater Treatment Plant, Tracy, Minnesota

TRACY STP is a municipal wastewater treatment plant located in Tracy, Lyon County, Minnesota. Serving a population of about 2,142, the facility is part of the region's infrastructure for managing domestic wastewater from this small community in the Upper Midwest. As a plant serving fewer than 10,000 people, TRACY STP falls under the US Clean Water Act framework, which requires secondary treatment as a baseline for municipal wastewater. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Minnesota Pollution Control Agency, ensuring compliance with water quality standards for the receiving environment. The plant discharges into local waterways that ultimately drain into the Minnesota River basin, a major tributary of the Mississippi River. This watershed supports diverse aquatic life and is important for regional water quality. The treatment process helps protect downstream ecosystems from nutrient pollution and pathogens.

TRACY STP discharges into the Minnesota River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic species and is part of a larger system affected by agricultural runoff. Effective treatment helps reduce nutrient loading that can contribute to hypoxia in the Gulf.
