RE: Eastern Fields Wind Farm…

RE: Eastern Fields Wind Farm Attenti, and mass imbalance between blades. A slim layer of ice at the leading edge increases noise and shifts the frequency to higher levels. This imbalance also contributes to an increased risk of mechanical failure and even blade failure. Not only does ice accretion present a risk, but the recent turbine and blade failures, give anyone who travels the roads, serious doubt about the location of IWT’s at such close proximity to roadways. The most recent Vestas V80 Turbine incident in Huron, sent debris from 140m to 450m from the center of the tower. It would not take more than one partial blade failure or one ice or debris fling event, especially into the path of a vehicle/ farm machinery/snow mobile, to create a crisis. The PSA from roadways may meet the minimum Ontario requirement but does not provide any guarantee of protection. The internationally accepted formula for determining safe setback is hub height, plus blade diameter x 1.5. The potential advantage of wind energy produced is not worth any such risk. Legal action will result from any such incident. We cannot rest on setbacks proposed in 2009 when hub heights were less than half of what the turbines at Eastern Fields are proposed to be, to protect us. Ignorance of physics/science in general is no excuse.
