As a US facility, the plant is subject to the Clean Water Act and operates under an NPDES permit issued by the Pennsylvania Department of Environmental Protection. For plants of this scale, secondary treatment is typically required, with additional nutrient removal standards applicable in the Chesapeake Bay watershed to reduce nitrogen and phosphorus loads. The plant's treated effluent discharges into a local stream that flows into the Susquehanna River, ultimately reaching the Chesapeake Bay. This watershed is ecologically significant, supporting diverse aquatic life and serving as a critical habitat for migratory fish species. The plant plays a key role in protecting downstream water quality.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life and important fisheries. Nutrient pollution from wastewater is a key concern, and plants in this basin often face enhanced treatment requirements to protect the bay's ecosystem.
