CARLILE LOGISTICS CORPORATION Stormwater Outfall, Anchorage, Alaska

CARLILE LOGISTICS CORPORATION manages a stormwater outfall located at 1800 E 1ST AVE in Anchorage, Alaska. This facility handles stormwater discharge from industrial logistics operations, classified under NAICS codes 484121 and 484122 for general freight trucking. As a stormwater outfall, it is part of the broader municipal separate storm sewer system (MS4) in Anchorage, which falls under Phase II NPDES MS4 permit requirements. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) for stormwater discharges. Industrial stormwater outfalls like this one must comply with EPA's Multi-Sector General Permit (MSGP) or an individual permit, depending on the nature of the industrial activity. The Anchorage area experiences a subarctic climate with significant snowmelt, which influences stormwater runoff patterns and pollutant loading. Environmental significance includes potential impacts on local water bodies receiving stormwater discharge, such as Cook Inlet. The facility's location in an industrial area means runoff may contain pollutants like sediment, oil, and grease from trucking operations. Proper management of stormwater quality is essential to protect aquatic habitats and comply with water quality standards under the Clean Water Act.

Anchorage's subarctic climate with heavy snowfall and spring melt creates unique stormwater challenges. Industrial facilities like this one contribute runoff that may carry pollutants such as sediment, hydrocarbons, and heavy metals into receiving waters like Cook Inlet. The area's sensitive aquatic ecosystems require effective stormwater management to prevent degradation of water quality and habitat.
