POA-2009-01156, Snake River

Expiration date: 8/3/2020

Melissa Jensen, with Alaska Department of Transportation and Public Facilities states that the project purpose is to repair Nome’s airport runways that have suffered significant surface wear and settling. Additionally, the purpose is to remove an abandoned mine tailings pond that is creating a bird strike hazard adjacent to runway 10-28. Work being proposed includes Rehabilitate Runway 10-28, Runway 3-21, North Apron, and the Runway Safety Area to include replacement of sub-base course materials and resurfacing. Other repairs include airport lighting replacements and/or upgrades including fixtures, signage, utilities associated with the airport runway operation, and new striping on replaced runway surface and associate facilities. Fill material for the repairs would come from an existing permitted commercial source. The fill material would be hauled to the airport and stored in uplands until use. Clean sub-base material stripped from the damaged portions of the runways would be discharged into the 2.6-acre abandoned mine tailings pond adjacent to Runway 10-28. Material would be discharged into the pond until the surface elevation matches the surrounding ground level. Excess sub-base material, asphalt, and other material stripped from the damaged portion of the runways and associated facilities would be stockpiled in uplands at the airport for long-term storage, re-use by Maintenance and Operations, or hauled away by the contractor for re-use on other projects. The only portion of the project requiring a Department of the Army permit (Section 404) would be the discharge of clean sub-base material into the 2.6-acre abandoned mine tailings pond. No material would be discharged in wetlands or other waters of the United States. Construction is expected to occur between June 2021 and September 2022. Work would be performed in accordance with the enclosed plan (sheets 1-2), dated July 1, 2020. The project site is located at Latitude 64.51464º N., Longitude 165.45718º W.; on the north side of airport runway 10-28, in Nome, Alaska.
