Overview
RAVN-GALENA AIRPORT is a stormwater outfall in Galena, Alaska, managing runoff from airport operations. It operates under US EPA NPDES MS4 regulations for stormwater discharge.
RAVN-GALENA AIRPORT is a stormwater outfall located at 900 Airport Rd in Galena, Alaska, within the Yukon-Koyukuk Census Area. As an airport facility, it manages stormwater runoff from impervious surfaces such as runways, taxiways, and parking areas. The facility is operational and falls under the regulatory framework of the US Clean Water Act, specifically the NPDES MS4 program, which governs stormwater discharges from municipal separate storm sewer systems. The facility's stormwater management is typical for airports in remote Alaskan regions, where snowmelt and rainfall can carry pollutants like deicing fluids, fuel residues, and sediment into nearby water bodies. The NAICS code 481111 indicates scheduled passenger air transportation, suggesting the airport handles commercial flights. Stormwater controls may include detention basins, oil-water separators, and regular monitoring to comply with permit requirements. Environmental significance lies in protecting the surrounding Yukon River watershed, which supports salmon and other aquatic life. Proper stormwater management at the airport helps prevent contamination from aviation-related pollutants, ensuring compliance with water quality standards and supporting the ecological health of the region.
Environmental context
The Galena area experiences a subarctic climate with long winters and significant snowmelt in spring, which can mobilize pollutants accumulated on airport surfaces. The Yukon River, a major waterway, is downstream and supports critical salmon habitats. Stormwater runoff from the airport may contain deicing chemicals, petroleum hydrocarbons, and sediment, posing risks to aquatic ecosystems. Regulatory oversight under the Clean Water Act requires the facility to implement best management practices to minimize these impacts.
