Karen Keesecker, Chugach Electric Association, Inc.; P.O. Box 16300; 1200 East 1st Avenue; Anchorage, Alaska 99519, telephone (907) 762-4726, and email: Karen_Keesecker@chugachelectric.com states the purpose is to serve the public interest by rebuilding and upgrading approximately 15 miles of existing 115kV transmission located between Girdwood and Indian. It would increase the transmission capacity to 230kV standards to maintain reliability and accommodate anticipated electrical load growth. Inspections conducted in 2007, concluded that the transmission line structures were nearing the end of their useful life and required replacement. The entire transmission line is 90.4 miles and runs from Quartz Creek Substation near Kenai Lake to the substation in Anchorage, which was originally constructed to carry power from the Cooper Lake Hydroelectric Power Plant to Anchorage. Today, this line also carries power produced by the Bradley Lake Hydroelectric Facility and the Nikiski Combined Cycle Power Plant. In addition to Anchorage, the line also serves local distribution substations at Indian, Dave’s Creek, Summit Lake, Hope, Portage, and Girdwood, and interconnects with the power grid for Seward, Kenai/Soldotna, and Homer. The project proposes to rebuild the electrical transmission segment between Girdwood Substation to Indian Substation (15 miles), which would require placement of 15,000 cubic yards of gravel and riprap and 305 cubic yards of pipe and concrete in 1.97 acres of waters of the U.S., including wetlands. The project is located within T. 10 N, R. 1 E, Sections 21-24, 29, 30; T. 10 N, R. 2 E, Section 1; T. 10 N, R. 1 W, Sections 5, 9-10,14-15, 24-25; T. 11 N, R. 1 W, Section 32 of the Seward Meridian. The proposed project extends from the Indian Substation (Latitude 61.000456° N, Longitude 149.499293° W) to the Girdwood Substation (Latitude 60.941448° N, Longitude 149.171027° W), near Girdwood, Alaska.
