Overview
Yakutat Airport stormwater outfall in Yakutat, Alaska, manages runoff from airport operations. It operates under US EPA NPDES MS4 permit requirements for stormwater discharges.
Yakutat Airport stormwater outfall is located at 1 Airport Rd in Yakutat, Alaska, serving the airport's drainage needs. As a stormwater outfall, it collects and discharges runoff from impervious surfaces such as runways, taxiways, and parking areas. The facility is operational and falls under the jurisdiction of the US Clean Water Act, likely requiring an NPDES permit for stormwater discharges associated with industrial activity. The airport's stormwater system is designed to manage runoff volume and quality, reducing the risk of flooding and pollutant transport to nearby water bodies. In Alaska, stormwater management must account for seasonal freeze-thaw cycles and permafrost conditions, which can affect drainage infrastructure. The facility's NAICS code 488119 (Other Airport Operations) indicates its role in supporting aviation activities. Environmental significance includes protecting local aquatic habitats in the Yakutat area, which is part of the Tongass National Forest and supports salmon runs. Proper stormwater management helps prevent erosion, sedimentation, and contamination from deicing chemicals or fuel spills. The outfall contributes to community resilience by mitigating flood risks during heavy rainfall or snowmelt events.
Environmental context
Yakutat is located in the temperate rainforest of Southeast Alaska, characterized by high annual precipitation (over 150 inches) and sensitive aquatic ecosystems. Stormwater runoff from the airport can carry pollutants such as sediment, deicing fluids, and petroleum hydrocarbons into nearby streams and the Gulf of Alaska. The region supports critical salmon habitats, making stormwater treatment essential for maintaining water quality and ecological health. Regulatory oversight under the Clean Water Act ensures that discharges meet water quality standards to protect these resources.
Frequently asked questions
The Yakutat Airport stormwater outfall is located at 1 Airport Rd in Yakutat, Alaska, United States.
It collects and discharges stormwater runoff from airport surfaces such as runways and parking areas, managing water quality and quantity to comply with environmental regulations.
Stormwater discharges from airports are regulated under the Clean Water Act through NPDES permits, often under the MS4 program for municipal separate storm sewer systems or industrial stormwater permits.
By controlling runoff, the outfall reduces pollutant loads from deicing chemicals, fuel, and sediment, helping to protect nearby streams and the Gulf of Alaska that support salmon and other aquatic life.
Alaska's freeze-thaw cycles and permafrost require stormwater infrastructure that can handle snowmelt and ice, preventing flooding and erosion while maintaining drainage during seasonal changes.
