USAF Clear Air Force Station Stormwater Outfall, Clear, Alaska | USA

USAF Clear Air Force Station is a stormwater outfall facility located in Clear, Alaska, within the Denali Borough. The facility manages stormwater runoff from the military installation, which is situated in a remote area of interior Alaska. As a stormwater outfall, it discharges collected runoff into local water bodies, operating under the regulatory framework of the US Clean Water Act and EPA's NPDES MS4 program. The facility is classified under NAICS codes 221112 (Electric Power Generation), 482112 (Rail Transportation), and 928110 (National Security), indicating a mix of industrial and institutional activities on site. Stormwater management at such facilities typically involves treatment or control measures to reduce pollutants before discharge. Given its location in a cold climate, seasonal considerations like snowmelt and frozen ground influence runoff patterns and treatment requirements. Operationally, the outfall serves the Clear Air Force Station, a key national security installation. Its stormwater management helps protect local water quality in the Tanana River watershed, which supports fish and wildlife habitats. The facility's remote location and military context underscore the importance of reliable stormwater infrastructure to prevent environmental impacts in a sensitive subarctic ecosystem.

The facility discharges into the Tanana River watershed, a region characterized by subarctic climate, permafrost, and boreal forests. Stormwater runoff from military and industrial activities can carry pollutants such as heavy metals, hydrocarbons, and sediment. The area supports salmon runs and other aquatic life, making water quality protection critical. Regulatory oversight under the Clean Water Act requires compliance with discharge limits to prevent impairment of these sensitive waters.
