A request for a Clean Water Act (CWA) §401 Water Quality Certification of a Department of the Army (DA) Permit application, Corps of Engineers’ Reference Number POA-2012-00768, Innoko River, has been received for the discharge of dredged and/or fill materials into waters of the United States (WOUS), including wetlands. After reviewing the application, DEC may certify there is reasonable assurance the activity, and any discharge that might result, will comply with the CWA, the Alaska Water Quality Standards, and other applicable State laws. DEC also may deny or waive certification.
Applicant: Department of Transportation and Public Facilities, 2301 Peger Road, Fairbanks, Alaska 99709, Melissa Jensen, Environmental Analyst, (907) 451-5377, firstname.lastname@example.org
Project Name: Shageluk Airport Access Road Improvements
Location: The proposed activity is located within Sections 15, 22, 26, 27, T. 31 N., R. 55 W.; Latitude 62.66124° N., Longitude -159.54055° W.; in Shageluk, Alaska.
Purpose: The applicant’s stated purpose is to maintain access from the City of Shageluk to the State-owned airport to improve driving safety. The project is needed as it is the only road providing access to the Shageluk Airport, and sections of the road are subject to erosion from the Innoko River. In addition, the surfacing has been severely degraded by use and must be resurfaced to provide a safe and maintainable driving surface. The loss of this access road would have significant adverse impacts on the community. The City of Shageluk is a remove community, the only reliable year-round transportation access, especially medical evacuation, is by air service.
Project Description: The project consists of reconstructing 2.7 miles of the existing airport access road, starting at the north bank of Hamilton Slough (aka Shageluk Slough) and ending at the airport property. The project will include minor road realignment, relocation of an overhead and underground electric power transmission line and resurfacing of the roadway with approximately nine inches of crushed surface course. The road realignment would shift the road a maximum of 67 feet east and is necessary to provide a safety buffer between the road and section of riverbank where river erosion has completely removed the road’s shoulder. The realignment would also provide room for reestablishing a new roadway shoulder. The surfacing material would be mined from Doyon’s 4.5 Mile Quarry located approximately 1.5 river miles north from the Shageluk Airport.
The project would require placement of 5,080 cubic yards (CY) of clean fill into 9.3 acres of jurisdictional WOUS, including wetlands. Of those, road construction would impact 0.7 acre and expansion of the material site would impact the remaining 8.6 acres. The utility relocation would require 32 CY of excavation in wetlands to place power poles in the ground.
