Municipality of Anchorage (MOA)'s stated purpose for the proposed project is to receive and manage the sediment collected from the MOA street and storm water maintenance activities. The liquids removed from the sediment would be discharge to the Anchorage Water and Wastewater Utility (AWWU) sanitary sewer and the sediment would be disposed of offsite. The proposed project would discharge 94,000 cubic yards of granular classified fill into 5.79 acres of wetlands for the construction of a Stormwater Sediment Management Facility. The proposed project would separate (decant) and process sediments removed from the MOA storm drain system during routine maintenance activities. During these activities, vacuum powered equipment (Vactor Trucks) would remove accumulated sediments from the pipes, manholes, catch basins and other structures in the storm drain networks. The combined water and sediment materials would be brought to the proposed project to be separated into liquids and solids. All liquids would be discharged into the wastewater system; the solids would be dewatered. Waste material would be removed to the municipal land fill, reusable materials would be removed to appropriate areas for reuse. No sediments would permanently accumulate at the proposed project site. Heavy equipment would be used to move materials between processing facilities at the proposed project site. Processed sediments would be removed from the proposed project in the spring. An estimated 70 to 100 truckloads of dried sediment would be removed per season.
