Yakutat Airport-Delta Western Operations Stormwater Outfall, Yakutat, Alaska

Yakutat Airport-Delta Western Operations is a stormwater outfall located at 640 Airport Road in Yakutat, Alaska, within the Yakutat City and Borough. This facility is part of the stormwater management infrastructure serving the airport and surrounding industrial area, operating under the jurisdiction of the United States Environmental Protection Agency (EPA) and the Alaska Department of Environmental Conservation. As a stormwater outfall, this facility discharges stormwater runoff from the airport and associated operations into local waterways. The facility is subject to the EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, which regulates stormwater discharges from industrial activities, including airports. Given its location in a remote coastal area of Alaska, the facility must comply with both federal Clean Water Act requirements and state water quality standards. The environmental significance of this outfall lies in its potential impact on nearby water bodies, including the Gulf of Alaska. Stormwater runoff from airports can contain deicing fluids, petroleum products, and other pollutants. Proper management and treatment of this runoff are critical to protecting the sensitive marine and aquatic ecosystems of the region, which support fisheries and wildlife.

Yakutat is located on the Gulf of Alaska, an area known for its rich marine biodiversity, including salmon, halibut, and marine mammals. The region experiences heavy precipitation, which increases stormwater runoff volumes. Stormwater discharges from industrial sites like airports can introduce pollutants such as deicing chemicals, heavy metals, and hydrocarbons into nearby waters, potentially impacting water quality and aquatic habitats. Regulatory oversight under the Clean Water Act aims to minimize these impacts through NPDES permits and best management practices.
