Overview
GKN Westland Aerospace, Inc. operates a stormwater outfall in Tallassee, Alabama, managing runoff from aerospace manufacturing under EPA NPDES MS4 regulations.
GKN Westland Aerospace, Inc. is an operational stormwater outfall located at 3951 Alabama Highway 229 in Tallassee, Elmore County, Alabama. The facility manages stormwater runoff from an aerospace manufacturing site, with NAICS codes 336412 and 336413 indicating aircraft engine and parts manufacturing. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulations. The facility operates under the U.S. EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, which governs stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, requiring facilities like GKN Westland to implement Stormwater Pollution Prevention Plans (SWPPPs) to control pollutants. The outfall likely serves a catchment area encompassing manufacturing buildings, parking lots, and storage areas, with treatment typically involving sedimentation basins, oil-water separators, or filtration systems to meet permit limits. Environmental significance lies in its role in managing runoff from an industrial site in the Tallapoosa River watershed. Proper stormwater management prevents contamination of local water bodies with sediments, heavy metals, and hydrocarbons from aerospace manufacturing. Compliance with NPDES permits ensures protection of aquatic habitats and downstream water quality, supporting community and ecological health in the Tallassee area.
Environmental context
The facility discharges into the Tallapoosa River basin, a waterway supporting diverse aquatic life and recreational uses. Industrial stormwater runoff from aerospace manufacturing can introduce pollutants such as heavy metals, oils, and solvents. The site's location in a mixed urban-industrial catchment requires robust best management practices to prevent impairment of receiving waters. Regulatory oversight under the Clean Water Act and Alabama's NPDES program aims to minimize ecological impact through permit limits and monitoring.
