The Thayer Lake Hydropower Development (TLHD) proposed project consists of a 1 megawatt or more run-of-river hydropower project located in the Tongass Forest in the Admiralty Island National Monument Park. The project area is located approximately 50 air miles south of Juneau. The hydroelectric plant would be a runoff-river facility using only the water available in the natural flow of the river. Under normal conditions, runoff-river facilities involve minimal water storage, and power generation fluctuates with the stream flow. The proposed facility would create a 10-20 acre pond behind a small dam. The hydroelectric facility would serve the community of Angoon, as directed in the Alaska National Interest Lands Conservation Act of 1980. The development has the potential of eliminating the need for diesel and fossil fuels for home heating and electric needs. In 2003, Kootznoowoo, Inc., the village corporation for the Angoon Community Association, asked the Forest Service to begin the National Environmental Policy Act process necessary to develop a hydroelectric facility. In 2004, Kootznoowoo submitted an application requesting Forest Service authorization for the project. The United States Department of Agriculture (USDA) prepared and issued an Environmental Impact Statement (EIS) for this project on February 20, 2009. The Record of Decision (ROD) for the project (R10MB-635) was issued May 2009 by the Forest Service, USDA. The application for funding to support pre-construction activities recognizes the ROD and commits to base project activities on the conditions as outlined in the ROD. The scope of the activities for which funding is proposed has been reviewed for NEPA, and the proposed activities (pre-construction activities up to and including final design of the TLHD project) are adequately bound by the USDA EIS.
