MATSON TERMINAL ANCHORAGE Stormwater Outfall, Anchorage, Alaska

MATSON TERMINAL ANCHORAGE is a stormwater outfall located at 1717 Tidewater Rd in Anchorage, Alaska. This facility manages stormwater runoff from a major shipping terminal, discharging into the local water system. As an industrial stormwater outfall, it is subject to the US EPA NPDES permitting framework, specifically under the Clean Water Act. The facility operates within the Anchorage Municipality, a Phase I MS4 area due to its population size. Stormwater outfalls like this one are regulated to control pollutants from industrial activities. The terminal's catchment includes port operations, cargo handling, and vehicle maintenance areas, which contribute typical industrial pollutants such as sediments, oils, and heavy metals. Environmental significance lies in its discharge to the Cook Inlet, a sensitive estuarine environment supporting salmon and marine life. Proper stormwater management is critical to prevent contamination from port activities. The facility's compliance with NPDES permit conditions helps protect water quality in this ecologically important region.

The outfall discharges into Cook Inlet, a dynamic estuary that supports critical salmon runs, marine mammals, and seabirds. Anchorage's industrial port activities generate stormwater runoff containing sediments, hydrocarbons, and metals. The facility must comply with EPA's industrial stormwater regulations to minimize impacts on this sensitive aquatic ecosystem.
