Overview
UPS-ANCHORAGE GATEWAY ANC-GP is a stormwater outfall in Anchorage, Alaska, serving a major logistics hub. It operates under US EPA NPDES MS4 permits for stormwater discharge.
UPS-ANCHORAGE GATEWAY ANC-GP is a stormwater outfall located at 6200 Lockheed Ave in Anchorage, Alaska, within the Anchorage Municipality. This facility manages stormwater runoff from a major logistics and cargo hub, supporting the operations of a key transportation gateway. As a stormwater outfall, it is part of the broader urban drainage system in Anchorage, a city with significant industrial and aviation activity. The facility operates under the regulatory framework of the US Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Anchorage is designated as a Phase I large municipality, requiring comprehensive stormwater management programs to control pollutants in runoff. The outfall likely handles runoff from impervious surfaces such as parking lots, aircraft aprons, and warehouses, typical of industrial stormwater discharges. Environmental significance lies in its role in managing stormwater quality in a cold-climate region, where snowmelt and freeze-thaw cycles affect runoff patterns. The facility helps mitigate the impact of urban and industrial runoff on receiving waters, such as Cook Inlet or local creeks, by conveying stormwater to treatment or detention systems. Proper operation is essential to protect aquatic habitats and comply with water quality standards.
Environmental context
Anchorage's stormwater management is influenced by its subarctic climate, with long winters and significant snowmelt in spring. Runoff from industrial areas like the airport can carry pollutants such as heavy metals, oils, and deicing agents. The facility discharges to waters that may be sensitive to urban runoff, requiring adherence to NPDES permit limits to protect aquatic life and recreational uses.
Frequently asked questions
