Falmouth Wind Turbine Document IEC 61400-11 Template- Noise Impact Assessment
Vestas Email To Falmouth Contract Engineer Shows Everyone Was Well Aware The Falmouth Turbines Were Well Above The IEC Design Standards
Falmouth Massachusetts USA March 23, 2017

The International Electrotechnical Commission (IEC) has been documenting wind turbine sound power levels measurements since at least 2002.

The IEC tracks and documents sound power level data provided by manufactures

The latest edition of the new International Standard IEC 61400-11 was prepared by IEC 61400-11 edition 3.0 year 2012. This edition replaces the second edition published in 2002.

The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees).
IEC 61400-11 TS (IEC, 2006a) deals with acoustic emissions from wind turbines.
The IEC cooperates closely with the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU). In addition, it works with several major standards development organizations, including the IEEE with which it signed a cooperation agreement in 2002, which was amended in 2008 to include joint development work.
The heart of the problem today is the installation of two Vestas V-82 commercial 1.65 megawatt wind turbines owned by the Town of Falmouth. The two turbines are replicas of Neg Micon NM -82 commercial 1.65 wind turbines. Vestas purchased Neg Micon prior to 2004.
Both Denmark where the Vestas turbines were built and the United States are members of the International Electrotechnical Commission (IEC).
Vestas wind turbine company had warned the Town of Falmouth their turbines generate 110 decibels of noise. The noise level warning is twice that of General Electric turbines used in the Falmouth wind studies.
The Town of Falmouth hid the Vestas 110 decibel noise warning until after 2013 when the Massachusetts Clean Energy Center admitted "mistakes" in the original acoustic noise studies. An email shows everyone involved in the original installation was aware of the IEC noise standards.
There is no wind turbine study for Falmouth Wind II or both turbines operating together.
The Massachusetts Technology Collaborative today the Massachusetts Clean Energy Center was the state agency who originally owned Falmouth Wind I.
The state agency had all the documents associated with the Vestas V 82 commercial 1.65 megawatt turbine.

Below an email from: Brian Hopkins, Vestas Representative To: Stephen Wiehe, Weston & Sampson ( Town of Falmouth contract engineer)
The email shows that prior to 5/28/2010 wind turbine installations before that in fact the Falmouth wind turbines exceed the International Electrotechnical Commission (IEC) standards.
The Vestas August 2010 110 decibel noise warning letter to the Town of Falmouth confirms the turbines were too loud to be placed near residential homes.
The August 2010 Vestas warning letter states the town had been previously warned about the noise levels.
The town by May of 2010 had been warned at least three times by Vestas wind company the turbines exceed IEC noise standards

RE: Sound / Feasibility Studies
TO: Wiehe, Stephen, cc Duijvesteijn, Olle; Yanuskiewicz, Francis
Steve, I don't believe I saw a feasibility study for Falmouth other than Site Plans. Was a sound study updated with the additional turbine?
Does the information I provided in the octave band data support the conclusions that you are conservatvely within MA state sound regulations?
The table highlights the fact that V82 produces greater decibels when it reaches its stall regime beyond the IEC design standard at 95% capacity.
The table also helps recognize the effects of shear on the sound levels experienced at receptors which should also be considering with the sound study.
My email was lost from the time we did the first turbine so I don't have a great record of information but do you have this decibel mapping for Falmouth?”

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
