The U.S. Department of Energy (DOE) is proposing to provide funding to the Native Village of Kiana for energy efficiency and retrofitting activities in Kiana, Alaska. These activities include light-emitting diode (LED) lighting retrofits; air sealing; retrocommissioning of the school building; and installation of automatic night setback thermostats, programmable thermostats, and occupancy sensors in community buildings as well as energy efficiency upgrades and heat recovery modifications at the power plant and water treatment plant (WTP). Locations where this work would occur include two school buildings, the health clinic, the city office building, the youth center, a warm storage building, Tribal office building, the fire hall, the power plant, and the WTP.

DOE has reviewed each of the proposed activities and the associated locations where those activities would occur. The activities listed above would require only minor modifications, if any, to the buildings involved and would not require any ground disturbing activities. There would be no change in the use, mission, or operations of existing facilities and no new permits are required for the proposed activities. Heat recovery modifications at the power plant and WTP would include replacing the heat recovery main piping with similar size piping with three inches of insulation and recharging of the system with glycol. Additionally, the alignment of the piping may be changed to reduce the piping distance between the power plant and the WTP. If the alignment of the piping is changed, minor ground disturbance may be required for the installation of an anchoring system for the piping. Any ground disturbance would occur within previously disturbed areas.
