The developer of a proposed wind farm in Roanoke County wants federal authorities to raise the flying altitude around four turbines deemed a hazard to airplanes.
Chicago-based Invenergy wants to build the wind farm atop Poor Mountain. The Federal Aviation Administration approved 14 of the project's 18 turbines in March.
The FAA said four turbines' highest point would exceed the minimum 4,200-foot altitude for planes flying into Roanoke Regional Airport.
The Roanoke Times reports that Invenergy submitted a plan to the FAA last week seeking special status for the four turbines. That would raise the minimum altitude for passing airplanes by 200 feet.
Invenergy business development manager Don Giecek says the developer will work with the FAA and county officials to address concerns.
