Overview
CARLILE TRANSPORTATION SYSTEM is a stormwater outfall in Fairbanks, Alaska, operating under US EPA NPDES MS4 regulations. It manages runoff from transportation and logistics activities.
CARLILE TRANSPORTATION SYSTEM is a stormwater outfall located at 900 Aurora Drive in Fairbanks, Alaska, within the Fairbanks North Star Borough. This facility manages stormwater runoff from transportation and logistics operations, classified under NAICS codes 484110 and 484121 for general freight trucking and long-distance truckload services. As a stormwater outfall, it discharges collected runoff into local waterways, subject to the Clean Water Act and NPDES MS4 permit requirements. The facility operates under Alaska's stormwater regulations, which align with the US EPA's Phase II MS4 program for small municipalities. Given its industrial catchment, the outfall likely requires a Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The site's location in Fairbanks, a subarctic climate with permafrost, presents unique challenges for stormwater management, including snowmelt and freeze-thaw cycles. Environmental significance lies in its role in preventing untreated runoff from transportation activities from entering nearby water bodies, such as the Chena River. Proper management reduces pollutant loads from vehicle fluids, road salts, and sediments. The facility contributes to local water quality protection in a region sensitive to climate change impacts on permafrost and hydrology.
Environmental context
Fairbanks is located in interior Alaska, where permafrost and extreme seasonal temperature variations influence stormwater runoff patterns. The Chena River, a tributary of the Tanana River, receives urban and industrial runoff. The region's cold climate leads to snowmelt-driven peak flows in spring, while summer rainfall can cause erosion and sediment transport. Industrial stormwater from transportation facilities may contain hydrocarbons, heavy metals, and deicing agents, posing risks to aquatic life in receiving waters.
