Overview
Continental Motors Inc operates a stormwater outfall in Mobile, Alabama, managing runoff from an aerospace manufacturing facility under US EPA NPDES MS4 regulations.
Continental Motors Inc operates a stormwater outfall located at 2039 Broad Street in Mobile, Alabama. This facility manages stormwater runoff from an aerospace engine manufacturing site (NAICS 336412) and is subject to the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permitting framework. As a Phase II small MS4, the outfall discharges into local waterways within the Mobile urban area. The facility's stormwater management involves controlling runoff from industrial activities, including potential pollutants such as oils, metals, and chemicals typical of aerospace manufacturing. Under the Clean Water Act, the outfall must comply with a Stormwater Pollution Prevention Plan (SWPPP) and may be subject to effluent limitations guidelines for the aerospace industry. The site's location in Mobile County places it within the jurisdiction of the Alabama Department of Environmental Management (ADEM) for permitting and enforcement. This outfall contributes to the broader stormwater infrastructure in Mobile, a coastal city with significant rainfall and proximity to the Mobile River and Mobile Bay. Effective management of industrial stormwater is critical to protect local water quality, particularly in an area with sensitive estuarine ecosystems. The facility's compliance with NPDES requirements helps mitigate the risk of pollutant discharge into impaired waters.
Environmental context
Mobile, Alabama, experiences a humid subtropical climate with heavy rainfall, averaging over 60 inches annually, which increases stormwater runoff volumes. The outfall discharges into the Mobile River watershed, which flows into Mobile Bay, an ecologically significant estuary supporting fisheries and wildlife. Industrial stormwater from aerospace manufacturing may contain metals, oils, and solvents, posing risks to aquatic life if untreated. The facility operates under NPDES MS4 Phase II requirements, which mandate best management practices to reduce pollutant loads to the maximum extent practicable.
