The U.S. Fish and Wildlife Service (Service) has finalized a compatibility determination (CD) evaluation documents for a transmission line rebuild from Three Johns Road to the U.S. Forest Service boundary at the Russian River within Kenai National Wildlife Refuge. The transmission line rebuild includes removing the existing 115 kV line and poles and replacing it with a 230 kV transmission line and poles accompanied with a fiber optic cable. The Service is completed evaluating the compatibility of this proposed activity, as required by agency policy (603 FW 2). Regulations applying to CD's within Alaska national wildlife refuges are found in 50 CFR 25.21.
