RAVN-UNALAKLEET AIRPORT Stormwater Outfall, Unalakleet, Alaska

RAVN-UNALAKLEET AIRPORT is a stormwater outfall located at Unalakleet Airport in Unalakleet, Alaska, United States. It operates within the NOME Census Area and manages stormwater runoff from airport infrastructure. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit framework. While specific discharge volumes are not detailed, airport stormwater systems typically handle runoff from impervious surfaces such as runways, taxiways, and parking areas. The NAICS code 481111 indicates scheduled passenger air transportation, suggesting the outfall serves a commercial airport. Located in a remote Alaskan community, the outfall plays a role in managing stormwater in a region with sensitive Arctic and subarctic ecosystems. Proper stormwater management helps prevent pollution from airport activities, such as deicing fluids and fuel residues, from entering nearby water bodies. The facility's operational status ensures continued compliance with environmental standards.

Unalakleet is a coastal community on the Norton Sound of the Bering Sea, with a subarctic climate and permafrost-influenced hydrology. Stormwater runoff from the airport can carry pollutants like deicing chemicals, petroleum residues, and sediment into local streams and the marine environment. The region supports salmon runs and migratory birds, making stormwater quality critical for ecosystem health. Regulatory oversight under the Clean Water Act and Alaska Pollutant Discharge Elimination System (APDES) ensures that discharges meet water quality standards to protect these sensitive habitats.
