SITKA FERRY TERMINAL WWTF Stormwater Outfall, Sitka, Alaska

SITKA FERRY TERMINAL WWTF is a stormwater outfall located at 5307 Halibut Point Rd in Sitka, Alaska, United States. The facility is operational and serves the Sitka Ferry Terminal, managing stormwater runoff from the transportation hub and surrounding infrastructure. As a stormwater outfall, it discharges collected stormwater into the local environment, likely into Sitka Sound or nearby water bodies. The facility operates under the regulatory framework of the US EPA NPDES MS4 program, which governs stormwater discharges in urbanized areas. Sitka is a small coastal city in Southeast Alaska, and the outfall is part of the municipal separate storm sewer system (MS4) that collects runoff from roads, parking lots, and other impervious surfaces. The NAICS codes associated with the facility (221320, 483114, 483212) indicate activities related to sewage treatment facilities and water transportation, reflecting the mixed-use nature of the terminal area. The environmental significance of this outfall lies in its role in managing stormwater quality and quantity in a sensitive coastal ecosystem. Sitka is located in the Tongass National Forest, a temperate rainforest with high precipitation, making stormwater management critical to prevent erosion, flooding, and pollution of marine habitats. The outfall helps mitigate the impact of urban runoff on Sitka Sound, which supports fisheries and wildlife.

Sitka, Alaska, is situated in a coastal temperate rainforest with high annual rainfall, making stormwater management crucial for preventing erosion and flooding. The outfall discharges into Sitka Sound, a marine environment that supports salmon, herring, and other aquatic species. Urban runoff from the ferry terminal and adjacent areas can carry pollutants such as oil, grease, and sediment, which the outfall helps to manage under NPDES MS4 permit requirements.
