PIT #4 (AKA T-III) Stormwater Outfall, Prattville, Alabama | USA

PIT #4 (AKA T-III) is a stormwater outfall located on County Road 4 near the Prattville Landfill in Prattville, Alabama, United States. This facility manages stormwater runoff from an industrial catchment area, likely associated with mining or related activities given its NAICS codes (212325, 212399). As a stormwater outfall, it discharges collected runoff into nearby waterways, playing a key role in local flood control and water quality management. Operational under the US EPA's National Pollutant Discharge Elimination System (NPDES), this outfall is subject to regulations for Municipal Separate Storm Sewer Systems (MS4) and industrial stormwater permits. The facility's location near a landfill suggests it handles runoff from waste management and industrial sites, requiring compliance with Clean Water Act standards to prevent pollution of receiving waters. Typical stormwater outfalls in Alabama must address sediment, nutrients, and potential contaminants from urban and industrial sources. This outfall contributes to the stormwater infrastructure of Autauga County, helping to manage runoff from the Prattville area. Its proximity to the landfill underscores the importance of monitoring for leachate or other pollutants. Effective operation supports local environmental health by reducing flooding risks and protecting water quality in downstream ecosystems, such as the Alabama River watershed.

The outfall discharges into the Alabama River basin, which supports diverse aquatic habitats and is used for recreation and water supply. Stormwater runoff from industrial and landfill areas can carry pollutants like heavy metals, sediments, and chemicals, necessitating robust treatment and monitoring. Alabama's stormwater regulations under the NPDES program aim to mitigate these impacts through best management practices and permit compliance.
