Overview
King Salmon Airport Stormwater Outfall in Alaska manages runoff from airport and industrial activities. It operates under EPA NPDES MS4 regulations for stormwater discharge.
King Salmon Airport Stormwater Outfall is a stormwater management facility located at Mile 1 of the Alaska Peninsula Highway in King Salmon, Alaska, United States. It serves the airport and surrounding industrial areas in Bristol Bay County, handling stormwater runoff from impervious surfaces and operational areas. As a stormwater outfall, it is part of the broader stormwater infrastructure in the region, which is subject to the US EPA NPDES MS4 permit program. The facility operates under the regulatory framework of the Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) for Municipal Separate Storm Sewer Systems (MS4). Given its location in a remote area of Alaska, the outfall likely manages runoff from airport operations, including deicing activities and fuel handling, which can introduce pollutants. The NAICS codes associated with the site (488111, 488119, 488190) indicate air traffic control, airport operations, and other support activities, suggesting a mix of commercial and industrial stormwater sources. Environmentally, the outfall discharges into the Bristol Bay watershed, a region known for its pristine ecosystems and important salmon fisheries. Stormwater runoff from the airport could potentially impact local water quality if not properly managed. The facility's operational status ensures ongoing compliance with federal and state stormwater regulations, aiming to minimize the ecological footprint of airport activities in this sensitive area.
Environmental context
The King Salmon Airport Stormwater Outfall discharges into the Bristol Bay watershed, a region of high ecological value supporting major salmon runs and diverse wildlife. Stormwater runoff from airport operations, including deicing agents and fuel residues, poses potential risks to water quality. The facility operates under EPA NPDES MS4 permits, which require best management practices to control pollutants and protect downstream aquatic habitats.
Frequently asked questions
The outfall is located at Mile 1 of the Alaska Peninsula Highway in King Salmon, Alaska, within Bristol Bay County.
It manages stormwater runoff from the airport and associated industrial areas, discharging treated or untreated runoff into local waterways under EPA NPDES MS4 permits.
Common pollutants include deicing fluids (ethylene glycol), fuel residues, heavy metals, and sediment from impervious surfaces, which require management to protect water quality.
The outfall is regulated under the US Clean Water Act through the EPA NPDES MS4 permit program, which requires stormwater pollution prevention plans and best management practices.
Airports have large impervious areas and use chemicals like deicers, making runoff a potential source of pollution. Proper management protects downstream ecosystems and complies with environmental laws.
