Overview
DEPT OF WELFARE POLK BORO STP serves approximately 2,872 residents in Polk, Pennsylvania. The plant operates under the US Clean Water Act's NPDES permitting program for municipal wastewater treatment.
The DEPT OF WELFARE POLK BORO STP is a municipal wastewater treatment facility located on Main Street in Polk, Venango County, Pennsylvania. It serves a population of about 2,872 people in this small borough and surrounding areas. The plant is part of the region's infrastructure for managing domestic wastewater. As a US facility serving fewer than 10,000 people, it falls under the EPA's NPDES permitting framework, which requires secondary treatment as a baseline. Typical plants of this scale in Pennsylvania use activated sludge or lagoon systems to meet state and federal effluent limits. The plant discharges treated wastewater to a local waterway, likely a tributary of the Allegheny River, which flows into the Ohio River and ultimately the Mississippi River system. The receiving waters support aquatic life and are used for recreation and drinking water downstream. The plant's operation helps protect water quality in the Allegheny River basin.
Environmental context
The plant's discharge enters a small stream in the Allegheny River watershed, which drains into the Ohio River and then the Mississippi River to the Gulf of Mexico. This inland location means the plant's effluent affects freshwater ecosystems, including fish and macroinvertebrate communities. The Allegheny River is designated for aquatic life and recreation, requiring effective nutrient and pathogen removal to prevent eutrophication and protect downstream uses.
