Carlile Aspen Facility Stormwater Outfall, Fairbanks, Alaska

The Carlile Aspen Facility is a stormwater outfall located at 1040 Aspen Street in Fairbanks, Alaska, within the Fairbanks North Star Borough. As a stormwater outfall, it discharges collected runoff from the surrounding catchment area, which includes industrial and urban land uses typical of the Fairbanks region. The facility is operational and serves as a point of compliance under the Clean Water Act. Stormwater outfalls in the United States are regulated under the National Pollutant Discharge Elimination System (NPDES), specifically through Municipal Separate Storm Sewer System (MS4) permits. Phase I and Phase II MS4 permits require operators to implement stormwater management programs to reduce pollutant discharges. The Carlile Aspen Facility, given its location in an urbanized area, likely falls under the jurisdiction of the Alaska Department of Environmental Conservation or the EPA for permitting and compliance. The environmental significance of this outfall lies in its potential impact on receiving waters in the Fairbanks area, such as the Chena River or Tanana River. Stormwater runoff from industrial and urban areas can carry pollutants like sediment, heavy metals, and hydrocarbons. Effective management of this outfall helps protect local water quality and aquatic habitats, which are important for the region's ecosystem and community.

Fairbanks, Alaska, experiences a subarctic climate with long winters and short summers, leading to unique stormwater challenges such as snowmelt runoff and permafrost interactions. The Chena River, a major water body in the area, is susceptible to pollution from urban and industrial runoff. The Carlile Aspen Facility discharges into this watershed, where contaminants like sediment, oil, and grease from nearby transportation and industrial activities can affect water quality. Regulatory oversight under the Clean Water Act aims to mitigate these impacts through best management practices and monitoring.
