Overview
ALYESKA PIPELINE SERVICE CO OPERATIONS MATERIAL SITE 114A-2 is a stormwater outfall located along the Dalton Highway in North Slope Borough, Alaska. It manages runoff from industrial operations in a remote Arctic environment.
ALYESKA PIPELINE SERVICE CO OPERATIONS MATERIAL SITE 114A-2 is a stormwater outfall situated at Dalton Highway mile 276.2 in the North Slope Borough, Alaska. This facility handles stormwater discharge from material site operations supporting the Trans-Alaska Pipeline System, a critical infrastructure corridor. The site operates under the U.S. EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, which governs stormwater discharges from industrial activities. As an industrial stormwater outfall in Alaska's North Slope, the facility is subject to NPDES permit requirements for construction and industrial activities, including erosion and sediment control measures. The remote Arctic location presents unique challenges for stormwater management, such as permafrost conditions and short construction seasons. The facility likely employs best management practices (BMPs) like sediment basins and erosion control to comply with Clean Water Act standards. The environmental significance of this outfall lies in its proximity to sensitive Arctic ecosystems, including tundra and potential fish-bearing waters. Proper stormwater management is essential to prevent sediment and pollutant discharge into nearby waterbodies. The facility's operational status indicates ongoing compliance with regulatory requirements to protect Alaska's fragile environment.
Environmental context
The North Slope Borough is an Arctic region characterized by permafrost, tundra, and sensitive aquatic habitats. Stormwater runoff from industrial sites like this outfall can carry sediments and pollutants that may impact water quality in receiving streams, which are often critical for fish and wildlife. The facility's location along the Dalton Highway, a major industrial corridor, means stormwater management must address both construction and operational runoff to minimize ecological disturbance in this fragile environment.
