CX-007915: Categorical Exclusion Determination

Response to Increasing Turbine Cut-ln Speed at the Sheffield Wind Farm, Vermont
CX(s) Applied: A9, B3.3
Date: 01/30/2012
Location(s): Vermont
Offices(s): Golden Field Office

Under this proposed project, the subcontractor would: (1) conduct a field assessment to determine the difference in bat fatality rates at turbines with different changes in the cut-in speed relative to fully operational turbines; and 2) ascertain the actual economic costs of the study and estimated costs for the entire project area under different curtailment prescriptions and timeframes. The project would begin in April 2012 with the experimental monitoring phase starting in June and continuing through September 2012. The study would be repeated during the same time periods in 2013.
