WRANGELL MARINE SERVICE CENTER Stormwater Outfall, Wrangell, Alaska

WRANGELL MARINE SERVICE CENTER is a stormwater outfall located at 205 Burger Street in Wrangell, Alaska, United States. This facility is part of the stormwater management infrastructure serving the Wrangell-Petersburg region, handling runoff from marine service and industrial activities. As a stormwater outfall in Alaska, this facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework. Stormwater discharges from industrial activities, including marine service centers, are typically regulated under the Clean Water Act's Multi-Sector General Permit (MSGP) or individual permits. The facility's location in a coastal Alaskan community means it must address challenges such as cold climate hydrology and potential impacts on sensitive marine ecosystems. The environmental significance of this outfall lies in its role in managing stormwater quality in a coastal Alaskan environment. Proper stormwater management helps protect receiving waters, including the nearby Wrangell Narrows and surrounding marine habitats, from pollutants associated with marine service operations such as oil, grease, and heavy metals.

Wrangell is located on Wrangell Island in Southeast Alaska, a region characterized by temperate rainforest, high annual precipitation, and extensive marine ecosystems. Stormwater runoff from industrial areas like the marine service center can carry pollutants such as hydrocarbons, heavy metals, and sediments into nearby water bodies. The facility's discharge likely enters the Wrangell Narrows, a critical habitat for salmon, herring, and other marine species. Regulatory oversight under the Clean Water Act aims to minimize these impacts through best management practices and effluent limits.
