Abstract
Klondike III Wind Project, located in Sherman County, Oregon is a wind-powered electric generating plant with an average electric generating capacity of approximately 125 megawatts (MW) and a peak generating capacity of not more than 375 MW (OEFSC, 2007). It was developed and is operated by Klondike Wind Power III LLC (Iberdrola Renewables, originally PPM Energy) of Portland, Oregon. There are two phases, referred to simply as Klondike III (Phase 1) and Klondike IIIa (Phase 2), both permitted by the State of Oregon through the Energy Facility Siting Council (EFSC) process. Klondike Wind Power III LLC received a Site Certificate from the EFSC through the Oregon Department of Energy on June 30, 2006 and a Site Certificate for Klondike IIIa (KIIIa) on November 16, 2007. Klondike III Phase 1 (KIII) was commissioned and fully operational in October 2007 and consists of 125 turbines. Of these 125 turbines, 80 are 1.5 MW GE turbines and 44 are Siemens 2.3 MW turbines and there is one Mitsubishi 2.4 MW turbine. Phase 2 consists of 51, 1.5 MW turbines and was commissioned and fully operational June 21, 2008. The MW listed is a nameplate capacity and does not reflect actual production. Wildlife monitoring is required for each phase. KIIIa (Phase 2 or “the Project”) is the subject of this final wildlife monitoring report. The results of year one of the two-year study were previously submitted (Gritski et al. 2009a).
This final report summarizes methods and results of the two-year avian and bat monitoring study for the Klondike IIIa Wind Project (Phase 2) since the Project was constructed in late June 2008 including:
- Wildlife fatality monitoring including reporting of all casualties found, results of Carcass Removal and Searcher Efficiency Trials, and estimated fatalities per MW in eight categories (7 avian, 1 bat) as well as four primary groups, as described in the Klondike III Wind Project Wildlife Monitoring and Mitigation Plan (WMMP, pages A-5 and A-10) filed under the EFSC Site Certificate (OEFSC, 2007).
- Raptor nest monitoring surveys in 2008
- Post-construction avian use surveys, 2008–2010
Wildlife fatality monitoring results include all casualties found at the Project from August 11, 2008 through August 18, 2010, including all incidental finds, and casualties found during the “clean-up searches” conducted each year prior to formal monitoring. Monitoring year one (or year one) is defined as the period from August 11, 2008 through August 15, 2009; monitoring year two (or year two) is defined as the period from August 16, 2009 through August 18, 2010. Previously unidentified or unconfirmed specimens were examined after the end of the first and second years of monitoring to determine species where possible. If it was not possible to identify to species, the fatality was classified to genus or taxonomic group based on available evidence. Wildlife fatality estimates included in this report were summarized from data collected during the two-year monitoring study. Preliminary results of the first year of wildlife fatality monitoring, post-construction avian use surveys, and raptor nest surveys were previously reported in Gritski et al., 2009a; however, results presented in this final wildlife fatality report supersede all previously reported information.
