Overview
JUNEAU INTL is a stormwater outfall in Juneau, Alaska, United States. It manages stormwater runoff from the Juneau International Airport area, operating under US EPA NPDES MS4 regulations.
JUNEAU INTL is a stormwater outfall located at 1873 Shell Simmons Dr, Juneau, Alaska, within the Juneau International Airport complex. As a stormwater outfall, it discharges collected stormwater runoff from the airport and surrounding urban areas into local receiving waters. The facility is operational and falls under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which governs stormwater discharges in urbanized areas. Given its location in Juneau, Alaska, the facility operates in a coastal environment with significant precipitation and snowmelt, influencing stormwater volume and pollutant loads. The outfall likely serves a mixed catchment including airport infrastructure, commercial areas, and transportation corridors. Typical stormwater management practices in such settings include detention basins, oil-water separators, and sediment controls to mitigate impacts on receiving waters like Gastineau Channel. The environmental significance of JUNEAU INTL lies in its role in managing urban runoff to protect water quality in the sensitive marine ecosystem of Southeast Alaska. Proper operation helps prevent pollution from hydrocarbons, heavy metals, and sediments associated with airport and urban activities. The facility's compliance with NPDES permit requirements is critical for maintaining the ecological health of local waterways and supporting community water quality goals.
Environmental context
Juneau is located in the temperate rainforest of Southeast Alaska, receiving high annual precipitation that generates substantial stormwater runoff. The outfall discharges into Gastineau Channel, a marine waterbody that supports salmon, herring, and other aquatic life. Urban and airport runoff can carry pollutants such as petroleum hydrocarbons, de-icing chemicals, and sediment, posing risks to water quality and habitat. Regulatory oversight under the Clean Water Act and Alaska's water quality standards aims to minimize these impacts through best management practices and monitoring.
