Federal officials say most of the turbines at a proposed wind farm in Roanoke County won't be a hazard for airplanes.
Media outlets report that the Federal Aviation Administration approved 14 of the project's 18 turbines Wednesday.
Chicago-based Invenergy wants to build the wind farm atop Poor Mountain. The FAA says four turbines' highest point would exceed the minimum 4,200-foot altitude for planes flying into airports in Roanoke and Lynchburg.
Invenergy says that if a turbine can't be moved, it will be eliminated from the project.
The project also requires the approval of the county and the state.
