The Federal Aviation Administration (FAA) has reversed a decision that gave approval to the Massachusetts National Guard for proposed wind turbines for five locations at the Upper Case military base, the Cape Cod Times reports.
The FAA now says those five locations, which are used for military training, pose a presumed hazard to air navigation at heights above 213 feet.
Last week, the FAA approved eight of 17 sites at the Upper Cape military base, saying they pose no adverse effects to aviation. Height reductions of 177 feet to 225 feet are being recommended on seven of nine other locations.
In June, the National Guard filed a site plan with the FAA and Air Force Space Command for the review of 17 possible sites to locate wind turbines at the Massachusetts Military Reservation (MMR) on Cape Cod.
Jim Peters, a spokesman for the FAA, could not immediately explain how five of the sites were approved one week and were then found unacceptable six days later, according to the Cape Cod Times.
