Overview
Carpenter Technology Corp operates a stormwater outfall in Tanner, Alabama, managing industrial stormwater discharge under US EPA NPDES MS4 regulations.
Carpenter Technology Corp is an industrial stormwater outfall located at 22059 Thomas L Hammons Rd in Tanner, Limestone County, Alabama. The facility is operational and serves as a point of discharge for stormwater runoff from an industrial catchment, primarily associated with NAICS codes 236210 (Industrial Building Construction) and 332111 (Iron and Steel Forging). As a stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, specifically under the Clean Water Act's Phase II MS4 requirements for small municipalities and industrial facilities. The facility's technical specifications are not detailed in available records, but typical stormwater outfalls in industrial settings include structural controls such as retention basins, sediment traps, and oil-water separators to manage runoff quality. In Alabama, stormwater management is regulated by the Alabama Department of Environmental Management (ADEM), which enforces NPDES permits for industrial stormwater discharges. The facility's location in an industrial area near the Tennessee River watershed suggests potential concerns for downstream water quality. Operationally, Carpenter Technology Corp's stormwater outfall plays a role in managing runoff from industrial activities, helping to prevent flooding and reduce pollutant loads to local waterways. The facility contributes to community resilience by controlling stormwater volume and quality, aligning with broader environmental goals under the Clean Water Act. Its location in Tanner, a small town in northern Alabama, underscores the importance of industrial stormwater management in mixed-use catchments.
Environmental context
The facility discharges stormwater from an industrial catchment in Limestone County, Alabama, which drains into the Tennessee River basin. The region experiences a humid subtropical climate with frequent thunderstorms, leading to high runoff volumes. Industrial activities such as iron and steel forging can introduce pollutants like heavy metals, oils, and sediments into stormwater. The outfall's discharge may affect local water bodies, necessitating compliance with NPDES permit limits to protect aquatic life and downstream uses.
