ALTOONA EASTERLY STP - Logan Township, Pennsylvania Wastewater Treatment Plant

ALTOONA EASTERLY STP is a municipal wastewater treatment facility located at 412 East 6th Avenue in Logan Township, Blair County, Pennsylvania. The plant serves an estimated population of 29,994 people in the Altoona metropolitan area, situated in the central part of the state within the Appalachian region. As a US facility serving a medium-sized agglomeration, the plant is subject to the National Pollutant Discharge Elimination System (NPDES) permitting program under the Clean Water Act. This regulatory framework requires secondary treatment as a baseline for municipal wastewater plants, with more stringent standards for sensitive water bodies. The plant's operational details are managed through state-level oversight by the Pennsylvania Department of Environmental Protection. The treated effluent from the plant discharges into the local watershed, which is part of the Susquehanna River basin. The Susquehanna River flows southeast through Pennsylvania and Maryland before emptying into the Chesapeake Bay, the largest estuary in the United States. The plant's operations contribute to protecting downstream water quality in this ecologically significant watershed.

The plant discharges into the Susquehanna River basin, which drains into the Chesapeake Bay. This watershed supports diverse aquatic life, including migratory fish species such as American shad and river herring. The Chesapeake Bay is a vital estuarine ecosystem that relies on upstream nutrient management to prevent eutrophication and maintain water quality.
