US Army Garrison Fort Greely Stormwater Outfall, Fort Greely, Alaska

US Army Garrison Fort Greely is a stormwater outfall located in Fort Greely, Alaska, within the Southeast Fairbanks Census Area. The facility manages stormwater runoff from the military installation, which covers a significant area in a subarctic environment. As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory framework of the US Clean Water Act and EPA's NPDES MS4 permit program. The facility's technical specifications are limited, but as a military installation, the stormwater system likely handles runoff from industrial, residential, and training areas. The NAICS code 928110 indicates national security activities, which may involve specific stormwater management practices. In Alaska, stormwater management must account for permafrost, snowmelt, and short construction seasons, influencing system design and operation. Environmentally, the outfall discharges into the Tanana River watershed, which supports salmon and other aquatic species. The facility's operational status ensures ongoing management of stormwater quality and quantity, reducing risks of flooding and pollutant transport. Compliance with MS4 permit requirements is critical for protecting downstream water bodies in this sensitive boreal ecosystem.

The facility is located in a subarctic region with permafrost, where stormwater management must address snowmelt and frozen ground conditions. Discharge from the outfall enters the Tanana River watershed, a key habitat for salmon and other fish species. The area's remote location and military activities require careful management to prevent contamination from fuels, heavy metals, and other pollutants common on military installations.
