Tyonek Services Group Inc. Huntsville Hanger 1 Stormwater Outfall, Huntsville, Alabama

Tyonek Services Group Inc. Huntsville Hanger 1 is a stormwater outfall located at 2840 Wall Triana Highway in Huntsville, Madison County, Alabama. This facility manages stormwater runoff from an industrial site, likely associated with aerospace or logistics operations given the NAICS code 488190 (Other Support Activities for Air Transportation). As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory framework of the US Clean Water Act and Alabama's NPDES MS4 permit program. The facility's technical specifications are not detailed in available data, but typical stormwater outfalls in industrial settings include structures such as pipes, ditches, or channels designed to convey runoff. In Alabama, stormwater discharges are regulated under the Alabama Department of Environmental Management (ADEM) through NPDES permits, which require monitoring for pollutants and implementation of best management practices (BMPs) to minimize environmental impact. The facility's location in Huntsville, a major aerospace and technology hub, suggests the catchment area may include industrial impervious surfaces. Environmentally, this outfall contributes to the local stormwater management system, helping to control flooding and reduce pollutant loads entering receiving waters. The Tennessee River basin, which drains much of northern Alabama, is a significant ecological and recreational resource. Proper operation of this outfall is important for maintaining water quality in nearby streams and ultimately the Tennessee River, supporting both aquatic habitats and community water uses.

The facility discharges stormwater from an industrial area in Huntsville, Alabama, which is part of the Tennessee River watershed. This region experiences a humid subtropical climate with frequent rainfall, making stormwater management critical for flood control and water quality. The outfall likely drains impervious surfaces such as parking lots and buildings, potentially carrying pollutants like sediment, oil, and heavy metals. Regulatory oversight under the EPA's NPDES MS4 program requires permits and BMPs to protect receiving waters, which in this area support diverse aquatic life and recreational activities.
