OLD DOMINION FREIGHT LINE - HSV Stormwater Outfall, Huntsville, Alabama

OLD DOMINION FREIGHT LINE - HSV is a stormwater outfall located at 3378 Wall Triana Hwy SW in Huntsville, Madison County, Alabama. This facility manages stormwater runoff from a freight trucking operation, classified under NAICS 484122. As a stormwater outfall, it discharges collected runoff into local waterways, playing a key role in managing urban and industrial stormwater in the Huntsville area. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. Stormwater discharges from industrial activities are typically regulated under NPDES Multi-Sector General Permits or individual permits. The outfall is part of a network of stormwater controls designed to reduce pollutant loads from the site, including sediment, oil, grease, and other contaminants common to freight transportation facilities. Located in Huntsville, a rapidly growing city in northern Alabama, this outfall contributes to local stormwater management efforts. The Tennessee River basin receives runoff from the area, making proper stormwater treatment important for water quality. The facility's operational status indicates it is actively managing stormwater, supporting compliance with local and federal regulations aimed at protecting downstream water bodies.

The outfall discharges into the Tennessee River watershed, which supports diverse aquatic ecosystems and provides drinking water for communities downstream. Huntsville's industrial and urban growth increases impervious surfaces, elevating stormwater runoff volumes and pollutant loads. The facility's location in an industrial area means runoff may contain sediment, heavy metals, and hydrocarbons from trucking operations, requiring effective best management practices to mitigate impacts on receiving waters.
