Boeing Company Stormwater Outfall, Huntsville, Alabama | Industrial Runoff Management

The Boeing Company operates a stormwater outfall located at 499 Boeing Boulevard in Huntsville, Madison County, Alabama. This facility manages stormwater runoff from industrial and commercial operations, supporting compliance with the Clean Water Act and local MS4 permit requirements. As a major aerospace manufacturer, the outfall handles runoff from large impervious surfaces and industrial areas. The facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) framework, which regulates stormwater discharges from industrial activities. The outfall is part of Boeing's environmental management system, designed to control pollutants and prevent unauthorized discharges. Typical stormwater management practices include sedimentation basins, oil-water separators, and regular monitoring to meet permit limits. Located in Huntsville, a rapidly growing city in northern Alabama, the outfall contributes to local water quality protection by managing runoff from Boeing's manufacturing and R&D facilities. The region's climate, with frequent thunderstorms and heavy rainfall, increases the importance of effective stormwater control to prevent flooding and protect downstream water bodies such as the Tennessee River.

The outfall discharges into the Tennessee River basin, a major waterway in the southeastern United States. Huntsville's urban and industrial development has increased impervious surfaces, elevating stormwater runoff volumes and pollutant loads. The facility must comply with Alabama's NPDES general permit for stormwater discharges from industrial activities, which requires implementation of best management practices (BMPs) and monitoring for pollutants like sediment, oil, and heavy metals.
