Overview
Petersburg Ferry Terminal is a stormwater outfall in Petersburg, Alaska, USA. It manages runoff from a ferry terminal facility in the Petersburg Census Area.
Petersburg Ferry Terminal is a stormwater outfall located at 1100 South Nordic Drive in Petersburg, Alaska, within the Petersburg Census Area. This facility manages stormwater runoff from the ferry terminal infrastructure, serving the local transportation hub. As a stormwater outfall, it discharges collected runoff into nearby receiving waters, playing a role in managing urban runoff in this coastal Alaskan community. The facility operates under the regulatory framework of the US Clean Water Act, which governs stormwater discharges through the National Pollutant Discharge Elimination System (NPDES). In Alaska, the Environmental Protection Agency (EPA) oversees NPDES permits for stormwater outfalls, including those associated with transportation facilities like ferry terminals. The outfall likely falls under the EPA's MS4 (Municipal Separate Storm Sewer System) program, which regulates stormwater discharges from urbanized areas and transportation infrastructure. As a stormwater outfall in a coastal Alaskan town, this facility helps mitigate the environmental impact of runoff from the ferry terminal, which can carry pollutants such as oil, grease, and sediment from impervious surfaces. Proper management of stormwater is critical in this region to protect the surrounding marine ecosystem, including the waters of the Inside Passage. The facility's operational status ensures ongoing management of stormwater quality and quantity in compliance with federal regulations.
Environmental context
Petersburg is located on Mitkof Island in the Inside Passage of Southeast Alaska, an ecologically sensitive marine environment. Stormwater runoff from the ferry terminal can carry pollutants such as hydrocarbons, heavy metals, and sediment into nearby waters, potentially impacting aquatic habitats and water quality. The region's high precipitation levels increase runoff volumes, making effective stormwater management essential to protect local fisheries and marine ecosystems.
