POA-2016-355, North Klatt Bog

Expiration date: 10/14/2016

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.

POA-2015-119, Toksook River

Expiration date: 10/14/2016

Lower Kuskokwim School District's stated purpose is to renovate, upgrade and make additions to the existing school’s facilities to accommodate current and projected student numbers and meet the Alaska Department of Education and Early Development’s space requirements. Lower Kuskokwim School District applicant request authorization to discharge 6,600 cubic yards of gravel fill material into waters of the United States, including wetlands, resulting in a permanent loss of 1.8 acres of palustrine emergent wetlands adjacent to Toksook River. Lower Kuskokwim School District proposes to renovate and make additions to the existing school, relocate useable structures and demolish and replace dated structures. New infrastructure includes construction of a 38-foot by 90-foot pile-supported utility building, water tank and pad, and a new 15-foot by 20-foot generator pad with fuel tank pad and dispenser system connection to the utility building. A new 200 linear elevated utility duct would transfer treated wastewater from the utility building and terminate at a new sewer outfall located within an unnamed pond. Approximately 400 linear feet of buried utility duct for water and wastewater lines will be constructed north of the property, originating from the LKSD Annex, beneath Kaugia Street, and tie into the existing utility infrastructure. Additional work includes abandonment of the existing sewage lagoon, at the southeast corner of the property and installation of fencing around the proposed generator tank, water tank pads and proposed effluent receiving pond. Gravel would be discharged into jurisdictional wetlands for the purpose of providing work spaces for the contractor, storage yard areas and increase equipment accessibility to various locations within the project site, as well as, the construction of improved site drainage (i.e., ditches, swales).

POA-2016-270

Expiration date: 10/13/2016

Alaska Department of Transportation and Public Facilities' (ADOT&PF) stated purpose was to repair a breach in the embankment of Lost Creek and return creek flow to the main channel that crosses Nebesna Road at an existing low water crossing. The project site is located within Section 33, T. 9 N., R. 12 E., Copper River Meridian; USGS Quad Map Nabesna C-5; Latitude 62.517331º N., Longitude 143.174883º W.; near Nabesna, Alaska. WORK: Lost Creek breached one of its banks and proceeded to flow partially through a historic channel. This flow regime led to erosion along Nabesna Road and risking a historic native village and cemetery site. On July 1 and 2, the ADOT&PF discharged 5550 cubic yards of fill along 1120 linear feet of embankment of Lost Creek. The fill was to reinforce the Nabessna Road and build up the embankment to contain the flow of Lost Creek into its main channel. All work was performed in accordance with the enclosed plan (sheets 1-3), dated July 14, 2016. Please contact Ms. Amanda Whittier at (907) 753-5582, toll free from within Alaska at (800) 478-2712, or by email at Amanda.L.Whittier@usace.army.mil if further information is desired concerning this notice.
