UNIV AREA JA SPRING CREEK STP - State College, Pennsylvania Wastewater Treatment

UNIV AREA JA SPRING CREEK STP is a municipal wastewater treatment plant located in State College, Pennsylvania, operated by the University Area Joint Authority. The facility serves a population of about 60,132, placing it in the medium-to-large agglomeration category for US inland plants. As a US facility, the plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits based on the Clean Water Act. For plants serving populations around 60,000, secondary treatment is typically required, with additional nutrient controls if the receiving water is sensitive. The plant discharges to Spring Creek, a tributary of the Bald Eagle Creek, which flows into the West Branch Susquehanna River and ultimately reaches the Chesapeake Bay. This watershed is part of the Chesapeake Bay Program, which mandates nutrient reduction targets to protect the bay's ecosystem.

The plant discharges into Spring Creek, a coldwater fishery that supports native brook trout and other sensitive aquatic species. Spring Creek flows into Bald Eagle Creek, then the West Branch Susquehanna River, which drains into the Chesapeake Bay. The Chesapeake Bay is a large estuary facing eutrophication challenges, making nutrient removal at upstream plants critical for bay health.
