DSG Cantwell Pit Stormwater Outfall, Cantwell, Alaska | United States

DSG Cantwell Pit is a stormwater outfall located in Cantwell, Alaska, United States. It is situated along the Parks Highway in Denali County, serving the local area's stormwater drainage needs. As a stormwater outfall, it discharges collected stormwater runoff into receiving waters, playing a key role in managing urban and roadway runoff in this remote region. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. While Alaska has both Phase I and Phase II MS4 designations, this outfall likely falls under general stormwater discharge regulations applicable to small MS4s in the state. The operational status is confirmed as active, indicating ongoing stormwater management. Given its location in Cantwell, near Denali National Park, the outfall discharges into waters that may be ecologically sensitive. Proper stormwater management is critical to prevent pollutants from entering pristine Alaskan waterways. The facility contributes to local flood control and water quality protection, supporting the community's infrastructure and environmental stewardship.

The outfall is located in Denali County, Alaska, an area characterized by subarctic climate and pristine natural landscapes. Stormwater runoff from the Parks Highway and surrounding areas can carry sediments, road salts, and other pollutants. Discharge into local water bodies requires careful management to protect aquatic habitats, especially given the proximity to Denali National Park. Regulatory oversight under the Clean Water Act ensures that stormwater discharges do not impair water quality.
