Overview
AIRPORT PIT is a stormwater outfall located in Hoonah, Alaska, United States. It manages stormwater runoff in the Hoonah area, operating under US EPA NPDES MS4 regulations.
AIRPORT PIT is a stormwater outfall facility situated in Hoonah, Alaska, within the Skagway-Hoonah-Angoon Census Area. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding urban and potentially industrial catchment areas. The facility is operational and plays a role in managing stormwater in this coastal Alaskan community. In the United States, stormwater outfalls like AIRPORT PIT are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Depending on the population served, Hoonah may be subject to Phase II MS4 requirements, which mandate stormwater management programs to reduce pollutant discharges to the maximum extent practicable. The facility's location near the coast means it likely discharges into a water body that eventually reaches the Pacific Ocean. The environmental significance of AIRPORT PIT lies in its role in controlling stormwater runoff quality and quantity in Hoonah. Proper management helps protect local water bodies from pollutants such as sediment, oil, and heavy metals that can accumulate on impervious surfaces. The facility contributes to the community's infrastructure for flood control and water quality protection, supporting the ecological health of nearby streams and marine habitats.
Environmental context
Hoonah is located on Chichagof Island in Southeast Alaska, a region characterized by temperate rainforest, steep terrain, and high annual precipitation. Stormwater runoff in this area can carry sediment and pollutants from roads and developed areas into sensitive marine ecosystems. The facility's discharge likely enters waters that support salmon and other aquatic life, making effective stormwater management critical for maintaining water quality and habitat integrity.
