BNSF Railway - Winfield Stormwater Outfall, Alabama | US Stormwater Facility

BNSF Railway - Winfield is a stormwater outfall located at 50 Kirkwood Street in Winfield, Marion County, Alabama, United States. This facility is part of the BNSF Railway network and manages stormwater runoff from railway operations in the area. As a stormwater outfall, it serves as a discharge point for collected stormwater, typically regulated under the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. The facility operates under the regulatory framework of the Clean Water Act, which governs stormwater discharges from industrial activities, including railway operations. The NAICS code 482111 indicates it is associated with line-haul railroads. Stormwater outfalls like this one are designed to convey runoff from impervious surfaces such as tracks, yards, and maintenance areas, often incorporating best management practices (BMPs) to reduce pollutant loads before discharge. Located in Winfield, a small city in northwestern Alabama, the outfall discharges into local waterways that may ultimately feed into the Tennessee-Tombigbee Waterway system. The facility's operational status ensures ongoing management of stormwater quality and quantity, contributing to the protection of local water resources from potential contaminants associated with railway activities, such as oils, metals, and sediments.

The outfall is situated in a region with a humid subtropical climate, characterized by frequent rainfall events that generate significant stormwater runoff. The local waterways in Marion County are part of the larger Mobile River Basin, which supports diverse aquatic ecosystems. Stormwater discharges from industrial facilities like this railway outfall can introduce pollutants such as heavy metals, hydrocarbons, and suspended solids, potentially impacting water quality and aquatic life. Regulatory oversight under the NPDES MS4 program requires implementation of stormwater pollution prevention plans (SWPPPs) to mitigate these risks.
