To avoid potential impacts to Northern Long-eared Bats ("NLEB"), wind turbines are located
more than 1,000 feet from four shelterbelts and woodlots greater than 15 acres in size, will
feather blades to manufacturer's cut-in speed from sunset to sunrise during the bat active
period (April 15 - October 15), and will avoid tree removal from June 1 through July 31 to
minimize risk of impact to potential maternal roosts and other tree roosting habitat for NLEBS
and other bat species;
Minimize ground disturbance/clearing of potentially undisturbed land;
Avoid and/or minimize impacts to potentially suitable habitat for the Dakota skipper and
Poweshiek skipperling;
Avoid siting turbines in wetlands and waterbodies;
Design transmission facilities using APLIC guidance to minimize the risk of electrocution and
collisions of birds by power lines (APLIC, 2006; 2012);
Train staff to recognize eagles, and if observed, evaluate risk and respond appropriately;
Conduct post construction bird and bat monitoring in coordination with FWS and SD GFP.
