Dutch Harbor Satellite Yard #1 Stormwater Outfall, Unalaska, Alaska

Dutch Harbor Satellite Yard #1 is a stormwater outfall located at 1634 East Point Road in Unalaska, Alaska, within the Aleutians West Census Area. This facility manages stormwater runoff from an industrial catchment area, likely associated with the nearby port and transportation infrastructure. As a stormwater outfall, it discharges collected runoff into local water bodies, operating under the regulatory framework of the US Clean Water Act and EPA NPDES MS4 permits. The facility's NAICS code 484110 indicates a focus on general freight trucking, suggesting the site is a trucking yard or logistics hub. Stormwater management at such industrial sites typically involves treatment of runoff to remove pollutants like sediment, oil, and grease before discharge. The outfall likely serves a small to medium-sized catchment area, common for satellite yards in remote Alaskan communities. Dutch Harbor is a major fishing port in the Aleutian Islands, and the facility's stormwater management is critical to protecting the surrounding marine environment. The outfall discharges into the Bering Sea, a productive ecosystem supporting fisheries and wildlife. Proper stormwater control helps mitigate impacts from industrial activities, aligning with EPA's MS4 program goals for water quality protection.

The facility is located in Dutch Harbor, a key fishing port in the Aleutian Islands, discharging stormwater into the Bering Sea. This marine environment supports valuable fisheries and wildlife, making pollution control essential. The industrial catchment, including trucking operations, poses risks of sediment, oil, and grease runoff. Regulatory oversight under the EPA NPDES MS4 program aims to minimize these impacts through best management practices.
