Overview
Juneau International Airport Alaska Seaplanes stormwater outfall in Juneau, Alaska, manages runoff from airport and seaplane operations under EPA NPDES MS4 permit requirements.
Juneau International Airport Alaska Seaplanes is a stormwater outfall located at 8907 Yandukin Dr in Juneau, Alaska, within the Juneau City and Borough. This facility handles stormwater runoff from airport and seaplane operations, contributing to local drainage management in a coastal urban setting. The facility operates under the U.S. EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit program, which regulates stormwater discharges from large and small municipalities. As an airport-related outfall, it likely addresses runoff from impervious surfaces such as runways, taxiways, and parking areas, with typical controls including sedimentation basins and oil-water separators. Stormwater management at this site is important for protecting downstream water quality in the Gastineau Channel and surrounding marine environments. Proper treatment of runoff from aviation activities helps prevent pollutants like fuel residues and deicing chemicals from entering sensitive coastal ecosystems, supporting both regulatory compliance and community environmental health.
Environmental context
Juneau is located in a coastal temperate rainforest with high annual precipitation, making stormwater management critical for preventing erosion and pollutant transport. The outfall discharges into the Gastineau Channel, a marine waterway that supports salmon runs and other aquatic life. Runoff from airport operations may contain hydrocarbons and heavy metals, requiring effective treatment to protect these sensitive habitats.
