ALYESKA PIPELINE SERVICE CO OPERATION MATERIAL SITE 117-2BD - Stormwater Outfall in Deadhorse, Alaska

ALYESKA PIPELINE SERVICE CO OPERATION MATERIAL SITE 117-2BD is a stormwater outfall located in Deadhorse, Alaska, along the Dalton Highway at Milepost 290.35. This facility is part of the Alyeska Pipeline Service Company's operations, managing stormwater runoff from material sites and supporting infrastructure in the North Slope region. As a stormwater outfall, it discharges treated or untreated runoff into local waterways, subject to federal and state regulations. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, specifically under the Clean Water Act. Given its location in the Arctic, the facility must comply with Alaska's water quality standards and EPA requirements for industrial stormwater discharges. The site likely employs best management practices (BMPs) such as sedimentation basins, erosion controls, and spill prevention measures to mitigate environmental impacts. This outfall plays a critical role in managing stormwater from industrial activities in a sensitive Arctic ecosystem. The North Slope region is home to fragile tundra and permafrost, where improper stormwater management can lead to erosion, habitat degradation, and contamination of water bodies. The facility's operations are essential for minimizing the ecological footprint of pipeline maintenance and material extraction in this remote area.

The facility is located in the North Slope of Alaska, an Arctic region characterized by permafrost, tundra, and sensitive aquatic ecosystems. Stormwater discharges from industrial sites can carry sediments, hydrocarbons, and other pollutants that may impact local water bodies, including the Colville River watershed. The region supports wildlife such as caribou, migratory birds, and fish, making proper stormwater management critical to preserving habitat and water quality.
