Overview
TANNER is a stormwater outfall in Tanner, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for stormwater management.
TANNER is a stormwater outfall located at 20865 Sandy Road in Tanner, Alabama, within Limestone County. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, which includes industrial activities associated with NAICS code 332321 (Metal Window and Door Manufacturing). The facility is operational and falls under the regulatory oversight of the US Clean Water Act and the National Pollutant Discharge Elimination System (NPDES) MS4 permit program. Stormwater outfalls like TANNER are critical components of municipal separate storm sewer systems (MS4s) that collect and convey stormwater runoff. In Alabama, these systems are regulated under Phase II of the NPDES MS4 program, which requires permits for small municipalities and industrial facilities to control pollution in stormwater discharges. The facility's industrial catchment may involve runoff from manufacturing processes, parking lots, and other impervious surfaces, necessitating best management practices (BMPs) to reduce pollutant loads. The environmental significance of TANNER lies in its potential impact on local water bodies. Stormwater runoff can carry pollutants such as sediment, heavy metals, and chemicals into receiving waters. Proper management and compliance with NPDES permit conditions are essential to protect water quality in the Tennessee River watershed, which is a vital resource for the region. The facility's role in managing urban and industrial runoff contributes to community resilience against flooding and water pollution.
Environmental context
Tanner, Alabama, is located in the Tennessee River Valley, a region characterized by humid subtropical climate with frequent rainfall. Stormwater runoff from industrial and urban areas can carry pollutants like metals, hydrocarbons, and sediment into local streams and the Tennessee River. The area's karst topography may also influence groundwater recharge and contamination risks. Regulatory oversight under the Clean Water Act and NPDES MS4 permits aims to mitigate these impacts through stormwater management plans and pollution prevention measures.
