INSULFOAM FACILITY Stormwater Outfall, Anchorage, Alaska | United States

INSULFOAM FACILITY is a stormwater outfall located at 628 Western Drive in Anchorage, Alaska, United States. This facility manages stormwater discharge from an industrial site classified under NAICS 326140 (Polystyrene Foam Product Manufacturing). As a stormwater outfall, it directs runoff from the facility's catchment area into the local drainage system, operating within the regulatory framework of the US Clean Water Act. The facility operates under the National Pollutant Discharge Elimination System (NPDES) program, which governs stormwater discharges from industrial activities. In Alaska, the Alaska Department of Environmental Conservation (ADEC) administers the NPDES program, including general permits for industrial stormwater. The facility's discharge is subject to monitoring and best management practices to control pollutants such as sediment, oils, and chemicals typical of manufacturing sites. As part of Anchorage's urban stormwater infrastructure, this outfall contributes to managing runoff in a region with significant seasonal precipitation and snowmelt. The facility's role is to mitigate potential impacts on receiving waters, including local creeks and the Cook Inlet watershed. Proper stormwater management helps protect water quality and aquatic habitats in this ecologically sensitive area.

Anchorage, Alaska, experiences a subarctic climate with heavy seasonal precipitation and snowmelt, which can increase stormwater runoff volumes and pollutant loads. The facility's discharge enters a watershed that drains into Cook Inlet, an estuary supporting salmon, marine mammals, and migratory birds. Industrial stormwater from manufacturing sites like this one may contain pollutants such as suspended solids, hydrocarbons, and heavy metals, requiring effective treatment and management to protect these sensitive ecosystems.
