The Alaska Department of Natural Resources said in an April 13 public notice that the Director’s Office of the Division of Parks and Outdoor Recreation is considering the issuance of a Special Park Use Permit to Nuvista Light and Electric Cooperative authorizing field studies for the proposed Chikuminuk Lake Hydroelectric Project.
These field studies would be done in the summer and fall of this year. The proposed study area is within Wood-Tikchik State Park, with the studies to focus on land and water in and around Chikuminuk Lake and the Allen River. Studies will include the following: geophysical, geotechnical, survey and mapping, hydrology and water quality, terrestrial and aquatic biology, and recreation.
FERC put a notice in the April 3 Federal Register saying that on March 2, Nuvista Light and Electric Cooperative filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Chikuminuk Lake Hydroelectric Project. The project would be partially located on federal lands managed by the U.S. Fish and Wildlife Service in the Yukon Delta National Wildlife Refuge.
The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners’ express permission, FERC noted.
The proposed project would consist in part of a 1,325-foot-long, 128-foot-high concrete-faced rockfill dam; a 150-foot-long, 75-foot-wide powerhouse containing two vertical Francis turbine/generator units rated for 6.7 MW each, for a total installed capacity of 13.4 MW; and a 118-mile long, 138-kV transmission line leading from the powerhouse to a substation in the town of Bethel. The estimated annual generation of the Chikuminuk project would be 88.7 gigawatt-hours.
