HIGHWAY 17 PIT is a stormwater outfall located at 2579 AL Highway 17 in Hamilton, Alabama, within Marion County. This facility manages stormwater runoff from an industrial catchment, likely associated with mining operations (NAICS 212321 and 212399). As a stormwater outfall, it discharges collected runoff into local waterways, playing a key role in flood control and water quality management in the region. The facility operates under the regulatory framework of the US Clean Water Act and the EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Stormwater outfalls in Alabama are typically subject to Phase II MS4 requirements for small municipalities and industrial stormwater permits. The site's industrial classification suggests it may also comply with EPA's Multi-Sector General Permit for stormwater discharges from industrial activities. Environmental significance of this outfall includes its potential impact on receiving waters in the Tombigbee River watershed. Stormwater runoff from industrial sites can carry pollutants such as sediment, heavy metals, and hydrocarbons. Proper management and treatment of stormwater at this outfall help protect downstream water quality and aquatic habitats. The facility contributes to community resilience by reducing localized flooding and managing runoff from the Highway 17 corridor.
Environmental context
The HIGHWAY 17 PIT outfall discharges into the Tombigbee River basin, a system that supports diverse aquatic life and provides drinking water for communities in western Alabama. The surrounding area is characterized by mixed forest and agricultural land use, with the outfall serving an industrial catchment that includes mining operations. Stormwater runoff from such sites can introduce sediment and potential contaminants, making effective management critical to maintaining water quality in the region's streams and rivers.
