Union Chapel Road Site Stormwater Outfall, Northport, Alabama | USA

Union Chapel Road Site is a stormwater outfall located in Northport, Tuscaloosa County, Alabama, United States. As a stormwater outfall, it manages runoff from urban and industrial catchments, contributing to local flood control and water quality management. The facility is operational and falls under the regulatory framework of the US EPA NPDES MS4 program, which governs stormwater discharges in municipal separate storm sewer systems. In Alabama, stormwater outfalls like Union Chapel Road Site are subject to Phase II MS4 requirements for small municipalities, given Northport's population size. The facility's NAICS code 212321 indicates an industrial catchment related to construction sand and gravel mining, which may influence runoff characteristics. Typical stormwater management involves sedimentation basins, vegetated swales, or detention structures to reduce pollutant loads before discharge. This outfall plays a role in protecting local water bodies from urban runoff impacts, particularly in the Black Warrior River watershed. Effective stormwater management helps mitigate flooding, erosion, and pollution, supporting community resilience and environmental health in the Tuscaloosa region.

The facility discharges into the Black Warrior River watershed, which supports diverse aquatic habitats and is used for recreation and water supply. Urban and industrial runoff from Northport and surrounding areas can carry sediments, nutrients, and heavy metals, posing risks to water quality. Regulatory oversight under the Clean Water Act aims to minimize these impacts through best management practices and monitoring.
