Tenneco Powertrain Stormwater Outfall, Athens, Alabama | Industrial Runoff Management

Tenneco Powertrain is a stormwater outfall located at 1500 Freeman Ave in Athens, Limestone County, Alabama, United States. The facility is operational and serves an industrial catchment associated with automotive parts manufacturing (NAICS codes 336350, 336390, 336399, 339991). As a stormwater outfall, it discharges runoff from the industrial site, which is regulated under the US Clean Water Act through NPDES MS4 permits. The facility operates under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES), specifically for stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program. The outfall is subject to requirements for stormwater pollution prevention plans (SWPPP) and best management practices (BMPs) to control pollutants in runoff. Located in Athens, Alabama, the outfall discharges into local waterways that may ultimately flow into the Tennessee River basin. The facility's environmental significance lies in its role in managing stormwater from a manufacturing site, with potential impacts on water quality in receiving waters. Compliance with permit limits and implementation of effective BMPs are critical for protecting aquatic ecosystems in the region.

The stormwater outfall at Tenneco Powertrain discharges into receiving waters within the Tennessee River basin, a region characterized by diverse aquatic habitats. Industrial stormwater runoff can carry pollutants such as heavy metals, oils, and sediments, which may affect water quality and aquatic life. The facility's location in an industrial area of Athens, Alabama, means the outfall is subject to NPDES permit requirements aimed at minimizing pollutant loads through source control and treatment measures.
