MINERSVILLE STP - Cass Township, Pennsylvania Wastewater Treatment Plant

MINERSVILLE STP is a municipal wastewater treatment plant located in Cass Township, Schuylkill County, Pennsylvania. It serves a population of approximately 6,930 people, classifying it as a small to medium-sized facility within the state's wastewater infrastructure. The plant is situated inland, more than 50 kilometers from the Atlantic coast, and its operations are subject to state and federal environmental regulations. As a US-based facility, MINERSVILLE STP operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. The Pennsylvania Department of Environmental Protection (PA DEP) issues permits that set effluent limits to protect water quality. For a plant of this scale, secondary treatment is typically required, which includes biological processes to remove organic matter and suspended solids. Regulatory compliance ensures that discharge meets state water quality standards. The plant's treated effluent is discharged into a local waterway within the Susquehanna River basin, which ultimately drains into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and serving as a critical habitat for migratory birds and fish. The plant's operations contribute to the protection of this downstream ecosystem by reducing pollutant loads.

MINERSVILLE STP discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting a rich ecosystem including blue crabs, oysters, and striped bass. The plant's location in the Schuylkill County region means its effluent contributes to the overall nutrient and sediment loads entering the bay, making effective treatment important for downstream water quality.
