POLARIS CGD Stormwater Outfall, Huntsville, Alabama | US Stormwater Facility

POLARIS CGD is a stormwater outfall located at 237 Laracy Drive SW in Huntsville, Alabama, within Madison County. As a stormwater outfall, it discharges runoff from an industrial catchment area, likely associated with manufacturing activities given the NAICS code 336999 (All Other Miscellaneous Manufacturing). The facility is operational and falls under the regulatory framework of the US Clean Water Act and EPA NPDES MS4 permits. Stormwater outfalls like POLARIS CGD are critical components of municipal separate storm sewer systems (MS4s) that collect and discharge stormwater runoff. In Huntsville, which is part of a Phase II MS4 area, the facility must comply with local stormwater management programs to control pollutants. The industrial catchment suggests potential for higher pollutant loads, requiring best management practices (BMPs) to mitigate impacts. The environmental significance of POLARIS CGD lies in its role in managing stormwater quality in an urban-industrial setting. Discharges from such outfalls can affect receiving waters, potentially including impaired water bodies in the Tennessee River basin. Proper operation and maintenance are essential to reduce runoff pollution and protect local water resources.

Huntsville, Alabama, experiences a humid subtropical climate with frequent rainfall, making stormwater management crucial. The facility's industrial catchment may contribute pollutants such as heavy metals, oils, and sediments to local waterways. Discharges from POLARIS CGD could impact the Tennessee River watershed, which supports diverse aquatic life and recreational uses. Regulatory compliance under the NPDES MS4 program helps ensure that stormwater controls are in place to minimize environmental harm.
