November 28, 2014 Canadian Medical Association Journal blog

Carmen Krogh, BScPharm (retired), is a peer reviewed IWT health researcher and formerDirector of Publications and Editor-in-Chief of the CPS.

R Y McMurtry is Professor Emeritus (Surgery) of Western University (formerly University of Western Ontario). Dr. McMurtry was also anADM at Health Canada 2000-02

Industrial wind turbines (IWTs) are being erected at rapid pace around the world. Coinciding with the introduction of IWTs, some individuals living in proximity to IWTs report adverse health effects including annoyance, sleep disturbance, stress-related health impacts and reduced quality of life. [i],[ii],[iii],[iv],[v],[vi],[vii],[viii],[ix],[x],[xi],[xii] In some cases Canadian families reporting adverse health effects have abandoned their homes, been billeted away from their homes or hired legal counsel to successfully reach a financial agreement with the wind energy developer.[xiii]

To help address public concern over these health effects Health Canada (HC) announced the Health Canada Wind Turbine Noise and Health Study (HC Study) 2 years ago and brought forth preliminary results November 6, 2014.

Here we briefly comment on the HC Study results and provide some historical context.

Acknowledgement of IWT adverse health effects is not new. The term “annoyance” frequently appears when discussing IWT health effects.

In a 2009 letter the Honourable Rona Ambrose, disclosed:

“Health Canada provides advice on the health effect of noise and low-frequency electric and magnetic fields from proposed wind turbine projects…To date, their examination of the scientific literature on wind turbine noise is that the only health effect conclusively demonstrated from exposure to wind turbine noise is an increase of self-reported general annoyance and complaints (i.e., headaches, nausea, tinnitus, vertigo).” [xiv]

In 2009, the Canadian Wind Energy Association (CanWEA) sponsored a literature review which acknowledges the reported symptoms such as headaches, nausea, tinnitus, vertigo and state they “… are not new and have been published previously in the context of “annoyance”…” and are the “… well-known stress effects of exposure to noise …”[xv]

In 2011, a health survey of people exposed to IWTs in Ontario reported altered quality of life, sleep disturbance, excessive tiredness, headaches, stress and distress. [xvi]

In the same year, CanWEA posted a media release which advised those impacted by wind turbine annoyance stating “The association has always acknowledged that a small percentage of people can be annoyed by wind turbines in their vicinity. … When annoyance has a significant impact on an individual’s quality of life, it is important that they consult their doctor.”[xvii]

It turns out it’s not a small percentage of people annoyed by wind turbines. An Ontario Government report concluded a non-trivial percentage of persons are expected to be highly annoyed.

The December 2011 report prepared by a member of CanWEA for the Ontario Ministry of Environment states in the conclusions:

“The audible sound from wind turbines, at the levels experienced at typical receptor distances in Ontario, is nonetheless expected to result in a non-trivial percentage of persons being highly annoyed. As with sounds from many sources, research has shown that annoyance associated with sound from wind turbines can be expected to contribute to stress related health impacts in some persons.”[xviii]

The World Health Organization (WHO) acknowledges noise induced annoyance to be a health effect [xix] and the results of WHO research “…confirmed, on an epidemiological level, an increased health risk from chronic noise annoyance…”[xx]

HC also acknowledges noise induced annoyance to be an adverse health effect. [xxi],[xxii] The Principal Investigator of the recent HC Study also states “noise-induced annoyance is an adverse health effect”. [xxiii]

Canadian Government sponsored research has found statistically significant relationships from IWT noise exposure.

A 2014 review article in the Canadian Journal of Rural Medicine reports:

“In 2013, research funded by the Ontario Ministry of the Environment indicated a statistically significant relation between residents’ distance from the turbine and the symptoms of disturbed sleep, vertigo and tinnitus, and recommended that future research focus on the effects of wind turbine noise on sleep disturbance and symptoms of inner ear problems.” [xxiv]

Recently on November 6, 2014, HC posted on its website preliminary results of its HC Study[xxv]. Wind turbine noise “…. annoyance was found to be statistically related to several self-reporting health effects including, but not limited to, blood pressure, migraines, tinnitus, dizziness, scores on the PSQI, and perceived stress” as well as related to “measured hair cortisol, systolic and diastolic blood pressure.”

These troubling results come as no surprise. Since at least 2007 HC employees including the Principal Investigator of the HC Study recommended wind turbine noise criteria which they predict will result in adverse health effects. (i.e. result in an increase percentage highly annoyed).[xxvi],[xxvii],[xxviii]

Then turbines were built and HC spent 2.1 million dollars to find out it appears to have under predicted the impact of IWT noise. HC’s IWT noise criteria does not use a dose response based on IWT noise but rather road noise. But of course IWTs are not cars and peer-reviewed studies consistently document that IWTs produce sound that is perceived to be more annoying than transportation or industrial noise at comparable sound pressure levels. [xxix],[xxx]

IWT noise annoyance starts at dBA sound pressure levels in the low 30s and rises sharply at 35 dBA as compared to road noise which starts at 55 dBA. These findings are further supported by the HC Study’s preliminary results.[xxxi]

IWT noise characteristics that are identified as plausible causes for reported health effects include amplitude modulation, audible low- frequency noise (LFN), infrasound, tonal noise, impulse noise and night-time noise. [xxxii]

The logical solution would be to develop IWT noise criteria which will protect human health but that would present a barrier to wind energy development. Noise limits impacts IWT siting, cost of energy produced [xxxiii] and by extension corporate profits. The wind energy industry has actively lobbied governments to be granted IWT noise exposure limits which benefit their industry.

Canadians trying to understand this should be mindful the Government of Canada has invested and distributed significant amounts of public money to attract and support the wind energy industry. [xxxiv],[xxxv],[xxxvi],[xxxvii],[xxxviii],[xxxix],[xl],[xli] In addition to providing funding, the Government of Canada in collaboration with wind industry stakeholders has developed the Wind Technology Road Map (Wind TRM) [xlii] which Natural Resources Canada defined to be an “…industry-led, government supported initiative that has developed a long-term vision for the Canadian wind energy industry …”.[xliii]

Canada’s Wind TRM states “Members of the Steering Committee, government and our industry will be using this roadmap to direct the actions that are necessary for Canada to develop its vast wind resources.”[xliv] HC is a member of the Interdepartmental Wind Technology Road Map Committee [xlv] which was created to assist in the implementation of Canada’s Wind TRM. [xlvi] One of the “key action items” detailed in the Wind TRM calls for Government and Industry collaboration to develop and maintain government documents that address concerns raised about wind energy projects including that of noise, infrasound and other. [xlvii]

Some jurisdictions are trying to take action to protect their residents. For example, several municipalities in Ontario are trying to establish bylaws that protect from IWT noise. In Wisconsin, on October 14, 2014 the Brown County Board of Health unanimously approved a motion to declare the IWTs at a local project a Human Health Hazard. [xlviii]

It would appear HC’s research effort is too little too late. A non-trivial percentage of Canadians continue to experience adverse health effects. HC now has additional scientific evidence of the “conclusively demonstrated” effects from exposure to IWT noise. It is time for HC to take action to help Canadians maintain and improve their health.

Wind turbine noise and health: what the wind lobby doesn’t want you to know

The wind industry is dangerous to human health, posing risks to everything from dizziness and nausea to chronic stress and heart conditions

Lawrence Solomon, FR Comment, The Financial Post, November 25, 2014

A Canadian court will soon decide if wind turbines violate Canada’s Charter of Rights and Freedoms by posing a risk to human health. Charter case decisions can be convoluted but the fundamental question of health at issue here is straightforward. Wind turbines, from all that is today known and by any rational measure, represent a risk to those living in their vicinity.

Although the wind industry and its government backers tend to dismiss concerns, the evidence of harm in communities that host wind turbines is overwhelming. Literally thousands of people around the world report similar adverse health effects, some so serious that owners abandon their homes. Studies of noise from turbines — though few in number, short in duration, tentative in their findings and conducted by interested parties — point to dangers. As if these weren’t enough, basic science sounds the alarm on wind turbines.

Wind turbines produce audible sound waves known to cause what medical science calls “annoyance,” a state of health that can lead to a constellation of illnesses called wind turbine syndrome (WTS). As Health Canada reported earlier this month, following a Statistics Canada survey it commissioned of people living in the vicinity of wind turbines, “[wind turbine noise] annoyance was found to be statistically related to several self-reported health effects including, but not limited to, blood pressure, migraines, tinnitus [ringing in the ears], dizziness” and sleep disorders. The annoyance was also found to be statistically associated with objective measurements of chronic stress and blood pressure. Health Canada’s bottom line: “the findings support a potential link between long-term high annoyance and health.”

The audible sound waves — these have a frequency above 20 Hz — may be the least of the worries faced by those living near wind turbines. The turbines also produce copious amounts of sound waves below 20 Hz, making them inaudible to the human ear and thus, say wind proponents, harmless. Yet sound at this low frequency, known as infrasound, should not be thought of as faint or weak. The U.S. military has studied the use of infrasound in non-lethal weapons. Many mammals — giraffes, elephants, whales — communicate with each other at infrasound frequencies, even when many kilometres apart. Powerful infrasound waves, in fact, explain how animals sense the coming of earthquakes well before humans do — and why animals fled to safety during the calamitous Sumatran and Japanese tsunamis of recent years.

The wind power project that was proposed for the North Gower area was to be 8-10, 2.5 megawatt wind turbines. 1,000 homes would have been within 3 km of the turbines. No new project has yet been proposed under the new “procurement” process for large renewable power projects (which we don’t need)  in Ontario.

Wind farm Constitutional challenge now before the judges

Wind farm legal decision expected before January

Turbines near Ridgetown: environmental review tribunals ignore evidence of adverse health effects
Turbines near Ridgetown: environmental review tribunals ignore evidence of adverse health effects

Big money on one side, families on the other

Jonathan Sher, London Free Press, November 20, 2014

A judicial fight over the future of wind turbines in Ontario wrapped up Thursday with the fate of the province’s green energy law in the hands of judges.

On one side is big money, wind energy giants like Samsung and a Liberal government intent on becoming a world leader in creating green energy.

On the other are four families in Huron and Bruce counties whose homes are close to dozens of proposed turbines.

But while it seems a David and Goliath affair, the underdogs have enlisted a legal pugilist who Thursday seemed to dance circles around the arguments of his adversaries, wrapping up a four-day hearing in London with an emotionally-loaded challenge to three Superior Court justices.

“The system has utterly broken down,” said Julian Falconer. “You have been tasked with keeping these people safe.”

Falconer was the most dynamic of lawyers representing four families in Southwestern Ontario battling the building of wind farms.

It’s not the first time lawyers have challenged the Green Energy Act in court. Three years ago, wind opponents lost in court fighting a decision by an environmental review tribunal to allow a wind farm. But the 2011 effort had a handicap this one does not — it was a judicial review, in which judges must give deference to the tribunal.

This time, Falconer wants the three-judge panel to:

  • Halt, by issuing what’s called a stay, wind farms that are expected to be tested in January.
  • Rule the environmental tribunal violated the constitutional rights of wind opponents when it refused to allow new evidence from a Health Canada study.
  • Allow wind opponents to stop wind farms by showing they might be seriously harmed rather than proving they had been harmed.

The judges expect to issue a decision on the stay soon, and while they didn’t specify a date, it’s likely they’ll act by January.

Environmental review tribunals shield their eyes to contrary evidence, Falconer said.

“They keep the blinders on. They’re not interested in new information. They’re interested in getting the turbines up,” he said.

But lawyers for the government and wind companies disagreed, one arguing the Health Canada study only showed a link between turbines and annoyance and the early results hadn’t yet been peer-reviewed.

“It’s a work in progress,” said Darryl Cruz, who represents St. Columban Energy.

The decision by the environmental tribunal was correct and wind companies should be allowed to complete their wind farms, he said.

That’s a position one Niagara wind opponent has been fighting for about four years, moving from her Welland home to keep away from planned turbines.

“It’s just wrong,” Catherine Mitchell said.

Wind opponents say turbines cause dizziness, headaches, heart palpitations and other illness.

The government says that’s wrong and that neighbours are protected because turbines are placed at least 550 metres from homes.

Ontario has more than 6,000 wind turbines built, planned or proposed, mostly in the southwest. Turbines account for about 4% of Ontario’s power.

How much does it cost to demolish a wind turbine?

How much to take down a wind turbine?

Bonanza in scrap, or millions to demolish?
Bonanza in scrap, or millions to demolish?

Tom Collins, Farmers Forum, October 2014

Scaremongers say it will cost millions

Brinston–While some critics of wind turbines howl that the cost of the eventual teardown of a turbine is astronomical, the actual cost today would be $30,000 to $100,000, per turbine.

The bigger issue is, who is going to pay for it.

Municipalities are on the hook to ensure companies tear down or, in industry jargon, decommission a turbine, unless they’ve got a binding agreement with the wind power company. Some municipalities demand from wind turbine companies ongoing payments into protected (or escrow) accounts or bonds to set money aside annually to pay for decommissioning.

Some municipalities require a letter of intent from wind turbine companies to ensure they will be responsible for decommissioning. Some municipalities have no agreement at all, including Wolfe Island, said its mayor, Denis Doyle. TransAlta communications manager Stacey Hatcher said the decommissioning plans are between the company and the landowner and because of that, the info is confidential. [See editor’s note #1]

The 86 turbines on Wolfe Island, on the St. Lawrence River at Kingston, were built by Canadian Hydro Developers, later purchased by Trans Alta and there is no bond or escrow account in place. The company does, however, reimburse the island about $100,000 per year for hosting the project. Based on current decommissioning projects around the world, it can cost $30,000 to $10,000 [sic] to dispose of a turbine. If it were to cost $50,000 to remove each turbine on Wolfe Island, it would cost $4.3 million to remove them all. Of course, that price goes up over time. [See Editor’s note #2] Hatcher said the company plans to repower or recontract when they [sic] current contracts are up.

There are 10 three-megawatt wind turbines at Brinston, between Kemptville and Winchester, and the power company ProWind [see Editor’s note #3] pays $1,000 per megawatt per year over the next 20 years into an escrow account that will rack up $600,000 to pay for decommissioning. [Editor’s note #4]

Windlectric Inc. wants to build 36 turbines on Amherst Island where Statec Consulting said that decommissioning costs are up to Windlectric. Typically, decommissioning will not remove all of the concrete base, but that’s only the first few feet of concrete that went into the ground. [We’re done adding editor’s notes at this point.]

One of the most infamous decomissionings involved 37 decrepit turbines in Hawaii that stood unused for six years before they were taken down in 2012. Tawhiri Power estimated that the take-down cost $30,000 per turbine. [OK, one more; see Editor’s note #5]

The seven-turbine community-owned Black Oak Wind Farm in New York State will start construction in late 2014. The decommissioning plan would currently cost about $55,883 per turbine, although the project expects to generate at least $50,000 per turbine by selling it as scrap metal. The municipality agreement means the power company must pay $140,000 per turbine in escrow but also means the payment can be reviewed and changed if decommissioning estimates change.….

WCO Editor’s notes:

1. Many landowners were told that it was to their benefit to decommission the turbines themselves as there is so much scrap value in the turbines; this is untrue due to the quality of metal being used, and also the other costs of decommissioning such as crane rental, and disposal of the toxic components.

2. So, that would be the millions then…

3. ProWind, properly “Prowind,” does not own the Brinston project, and hasn’t for several years. It is now owned by EDP Renewables.

4. In the original negotiations with Prowind, the developer wanted the landowners and the municipality to be responsible for decommissioning costs. It was the local community group that brought these costs to the attention of the municipality, and played a significant role in the agreement now in place.

5. US dollars? Canadian dollars? Also, the size of the turbines and the machinery involved is a factor. The turbines erected in Hawaii over a decade again, and the turbines at Wolfe Island are now miniscule compared with the 500-foot-plus, 3 -MW behemoths being built and proposed.

New research: wind farm infrasound can cause hearing damage

Living close to wind farms could cause hearing damage

New research published by the Royal Society warns of the possible danger posed by low frequency noise like that emitted by wind turbines

Camilla Turner, The Telegraph, October 1, 2014

Living close to wind farms may lead to severe hearing damage or even deafness, according to new research which warns of the possible danger posed by low frequency noise.

The physical composition of inner ear was “drastically” altered following exposure to low frequency noise, like that emitted by wind turbines, a study has found.

The research will delight critics of wind farms, who have long complained of their detrimental effects on the health of those who live nearby.

Published today by the Royal Society in their new journal Open Science, the research was carried out by a team of scientists from the University of Munich.

It relies on a study of 21 healthy men and women aged between 18 and 28 years. After being exposed to low frequency sound, scientists detected changes in the type of sound being emitted from the inner ear of 17 out of the 21 participants.

The changes were detected in a part of the ear called the cochlear, a spiral shaped cavity which essential for hearing and balance.

“We explored a very curious phenomenon of the human ear: the faint sounds which a healthy human ear constantly emits,” said Dr Marcus Drexl, one of the authors of the report.

“These are like a very faint constant whistling that comes out of your ear as a by-product of the hearing process. We used these as an indication of how processes in the inner ear change.”

Dr Drexl and his team measured these naturally emitted sounds before and after exposure to 90 seconds of low frequency sound.

“Usually the sound emitted from the ear stays at the same frequency,” he said. “But the interesting thing was that after exposure, these sounds changed very drastically.

“They started to oscillate slowly over a couple of minutes. This can be interpreted as a change of the mechanisms in the inner ear, produced by the low frequency sounds.

“This could be a first indication that damage might be done to the inner ear.

“We don’t know what happens if you are exposed for longer periods of time, [for example] if you live next to a wind turbine and listen to these sounds for months of years.”

Wind turbines emit a spectrum of frequencies of noise, which include the low frequency that was used in the research, Dr Drexl explained.

He said the study “might help to explain some of the symptoms that people who live near wind turbines report, such as sleep disturbance, hearing problems and high blood pressure”.

Dr Drexl explained how the low frequency noise is not perceived as being “intense or disturbing” simply because most of the time humans cannot hear it.

“The lower the frequency the you less you can hear it, and if it is very low you can’t hear it at all.

“People think if you can’t hear it then it is not a problem. But it is entering your inner ear even though it is not entering your consciousness.”

Farmers Forum editorial on wind: I don’t want a turbine

Apparently, everyone is tickety-boo with Wolfe Island being turned into a factory--or are they?

Apparently, everyone is tickety-boo with Wolfe Island being turned into a factory–or are they?

Wind turbine woes

September 2014, Farmers Forum

Farmers Forum surveyed a big chunk of Wolfe Island residents and found that 75 per cent approve of or are indifferent toward the 86 wind turbines they’ve been living with for five years.

There are only two wind turbine projects in Eastern Ontario–one in Wolfe Island and one near Brinston, south of Ottawa. But Wolfe Island, surrounded by the St. Lawrence River at one end and Lake Ontario at the other, is a captive crowd. We easily surveyed 200 of the 1,400 residents lining up for the Kingston ferry or working in the hamlet of Marysville.

With such a high proportion of residents surveyed–one in seven–we captured a fairly good picture of how people feel about those gigantic white gosal posts with their three imposing blades. Of course, having a visual of a turbine makes a huge difference. On many properties on the 29-kilometer long island, you can’t even see the turbines.* From other vantage points, you can see more than 10.

We found that money makes a difference. Those landowners (many of them farmers) hosting one or more turbines, are delighted with the $10,000 to $14,000 they earn each year per turbine just to look at them. The wind turbine company hands over another $100,000 to the island annually. Improvements to the local outdoor rink are one of the many benefits. It’s like getting paid twice for having the good luck of living at the right place on the right island at the right time.

Not surprisingly, wind power companies in other areas of the province are now offering “hush” money to Ontarians living near a proposed wind turbine project. As I’ve said before, if a company wants to pay me $14,000 a year to put a wind turbine on my property, I’d move the garage in order to accommodate them. Change their mind and offer the turbine to my neighbour and suddenly that turbine doesn’t look so good. It’s kind of an eyesore and doesn’t it affect bird migration? Could this be the health issues that we hear about or am I just sick at the thought that I just lost $280,000 of free money over 20 years? I think I know the answer. But when you offer to cut me in on the monetary benefits of my neighbour’s turbine, I’m suddenly all sunshine and happy thoughts.

This is not to say there aren’t honest-to-goodness health risks. Farmers Forum has no reason to disbelieve those survey respondents who complain of low-level noise when the wind changes direction.

We’re losing $24,000 an hour on wind

This brings me to my only real beef against wind power. As happy as I thought I would be to have a turbine, I don’t want  one.

They are the biggest money losers in the history of the province. Not for Wolfe Islanders or anyone else who gets a wind turbine contract. But for everyone else forced to pay an electricity bill. Electricity costs have already risen 12.5 per cent each year for the past five years. There are more than 1,000 operating wind turbines and another more than 4,000 to go up in the province. Ontario’s auditor general says we can expect another 40 per cent price hike over the next few years in our electricity bills. By 2018, every Ontario family will be paying an extra $636 per year to go green. And why? So the province can claim to be the first green province or state in North America? Big deal.

Wind turbines are incredibly inefficient. In a major report last year, the Fraser Institute noted that 80 per cent of the power generated by wind turbines occur when Ontario doesn’t need the power. So, while the province pays 13.5 cents per kilowatt hour, it often resells is for 2.5 cents south of the border. The report, Environmental and Economic Consequences of Ontario’s Green Energy Act, observed that data from the Independent Electricity System Operator show Ontario loses, on average, $24,000 per operating hour on wind power sales. Numerous companies, including Kelloggs and Heinz, have closed plants because Ontario companies pay more for power than any other jurisdiction in North America.

Not “green”

To make matters worse, a wind turbine can contain more than 200 tonnes of steel and Chinese factories need the mining of even more tonnes of coal and iron to make them. Writes David Hughes in his book Carbon Shift, “A windmill could spin until it falls apart and never generate as much energy as was invested in building it.”

So, you can’t even call wind turbines green energy. It’s appalling that farmers have been lied to about the benefits. We’re wasting billions on a phoney cause.

Re-posted from Wind Concerns Ontario

WCO editor’s note: Although Farmers Forum was clear on the limitations of their survey they missed several key points: one, by surveying only people at the ferry dock and in a coffee shop, they may have missed people who stay on the island all day, but more important, as the Island has turbines on one half and none on the other, it would have been absolutely critical to define where the survey respondents actually live. They didn’t. Another key factor in any survey of community residents living with turbines is the fact that many turbine contracts force landowners to sign a non-disclosure agreement—in other words, if they have anything negative to say about the turbines, they can’t talk.

North Gower resident report on K2 wind project

25 Monday Aug 2014

A resident of North Gower recently visited Huron County, where the K2 wind power project is under construction by a consortium of Samsung, Pattern Energy, and Capital Power. The 270-megawatt 140-turbine power project is located in the Township of Ashfrield-Colborne-Wawanosh.

Billed as “one of Ontario’s most promising renewable energy facilities,” the project was the subject of an appeal (dismissed) and is now being appealed by local residents who are asking for a stay of construction.

Here is what our citizen reporter said:

I just returned from Huron Co from vacation next to the K2 plant which is well into construction. All dire predictions of construction problems have occurred, the concession roads in Ashfield are taking such a pounding from heavy trucks that the $15 m paid to the township won’t begin to replace the damaged roads. While last year no one would talk of wind turbines, this year they will talk of little else; over 85% of residents now are against K2. Very frustrating as it seems people have to experience the degradation to the community before they will pay attention. If such pressure had been applied to the council earlier, perhaps something could have been done. But, maybe not as some of the sitting members have signed on as leasees with Capital-Samsung, in an unbelievable conflict of interest.
Further south at Grand Bend the council is at least appealing a wind plant, probably with no effect but they are trying.
All the more reason to alert residents here of what will occur if a go ahead is ever given to the local wind plant. It will not be pretty to put it mildly, and the wind company will act immediately to expedite the project. By then it will be too late.
Despite being warned about the potential for problems with water (the water table is 12 inches from the surface), Samsung-Pattern-Capital proceeded with the wind project, with the approval of the Ontario government. Almost immediately after construction began, land was flooded and as far as we know, water continues to be pumped and trucked away from the project.

Brinston wind farm noise prompts MoE investigation

Turbine neighbour prompts noise probe by ministry

By Nelson Zandbergen – AgriNews Staff Writer, August, 2014

Ontarios Ministry of Environment and Climate Change installed the basketball-sized microphone atop a temporary 30-foot listening post in her backyard, along with a smaller meteorological tower.BRINSTON Leslie Disheau has her ear to the ground in South Dundas, and for 10 days last month, a very powerful ear trained on the sky around her Brinston home as well.

The ministrys move was prompted by Disheau and partner Glen Baldwins complaints about nighttime noise emanating from two industrial wind turbines on either side of their place, one to their immediate northwest, the other to the southeast. Comprising part of the 10-turbine South Branch project that went into serviceearlier this year, both of the nearest units are less than one kilometre away from the home the couple shares with their two teenaged children.

But Disheau, candidate for deputy mayor in the municipal election and a fierce critic of the turbine industry, feared that developer EDP Renewables was intentionally slowing the two windmills to quiet them down while the ministry data-collection and audio-recording effort was underway with her participation.

The Houston-based firm almost immediately learned about the microphone on the day of the install, she said with some frustration.

Located just down the road from the projects main depot, it wasnt more than three hours after the arrival of two ministry trucks in her driveway that EDP called the same ministry to question the presence of those vehicles, according to Disheau.

She says the audio technician putting up the equipment learned of EDPs inquiry while talking to his office bycell phone, then told her about it.

Wind developer has not filed a compliance report yet

Disheau expressed unhappiness that a mandatory post-construction noise report had yet to be publicly filed by the company itself, after putting the project into service in March.

In the meantime, over a 10-day period in July, the ministry captured its own sound data with Disheaus help. During those times she considered the turbines to be noisiest, she pressed a button inside her home, triggering the recording process via the outdoor microphone, which was tethered to audio equipment in a locked box.

Comparing the sound to that of a rumbling plane or jet, she got up at night when she couldnt sleep to push the audio recording button located at the end of a long cord connected to the stuff outside. She also kept an accompanying log as part of the initiative.

The noise is most acute, she said, when the direction of the wind causes the blades to swivel toward her home in perpendicular fashion.

Effect of multiple turbines not considered by government

She scoffed at regulations that mandate 500-meter setbacks to neighbouring homes, pointing out the rule doesnt take into account the cumulative, “overlapping” impact of multiple turbines that surround. Nor does the regulation change with the actual size of a turbine, she adds, asserting that, at 3-megawatts apiece, “these are the largest turbines in Ontario.”

Ultimately, the ministry will use the data collected by Disheau to create a report, which could potentially form the basis of ministry orders against the two offending turbines. “To shut them down at night so that people can sleep,” she said with a hopeful tone, though she also acknowledged the ministry may not issue orders. And even if it does, she expects the developer to appeal and appeal.

Disheau also said there are measures that municipal governments can undertake to curtail the noise, including a nuisance noise bylaw of 32 decibels, which recently survived a court challenge in another Ontario municipality. She espouses such a policy in South Dundas and will push for it at the council table if elected.

And this is a SMALL one...

And this is a SMALL one…

The South Branch wind “farm” has been operating since mid-March, but it didn’t take long for the first noise complaints to be registered. This wind power generation facility is the first of the 3-megawatt machines to operate in Ontario; many more, mostly in southwestern Ontario, are to follow. The increased capacity is a concern to people who have done research on wind turbines, as they are more likely to produce infrasound or sound pressure, which disturbs some people.

Noise complaints lead to monitoring

BRINSTON – It has been more than six months since the blades of the South Branch Wind Farm turbines began to spin, leaving more than one nearby resident with some sleepless nights.

“I call when it gets to the point I can’t tolerate it anymore and I go to the basement [to sleep],” Brinston resident Leslie Disheau, former president of the South Branch Wind Opposition Group, said. “It is an issue and I’m not the only person in town with the issue.”

Disheau, who is running for the Municipality of South Dundas’ deputy-mayor seat in this fall’s municipal election, has been staying close to home since the Ministry of the Environment (MOE) installed noise-monitoring equipment at her Brinston Road property last week.

“MOE contacted me and asked if they could put this noise monitoring equipment up,” Disheau said.

The two pieces of equipment measure wind speed and direction, barometric pressure, rainfall, and more, she said.

She has submitted three separate noise complaints so far. Every complaint must be filed with EDP Renewables’ project leader Ken Little and local MOE representative Terry Forrester to be officially registered.

During EDP’s first open community liaison meeting in March, a Brinston man spoke out about his own sleep disturbances, suggesting the turbines be shut off for a period during the early hours of the morning, beginning around midnight. At that time, Little confirmed that there had been one official complaint already registered. He also said an acoustic audit had been ordered, which he expected to get underway within two months of the meeting.

“EDP has not released their post-construction noise audit report,” Disheau said during an interview with the Winchester Press Fri., July 18.

In conversation with one of the MOE officials who installed the equipment, Disheau said she learned that the provincial authority also had not seen a report from EDP.

“They can take a long as they want,” she said, crediting the Green Energy Act with the responsibility for not specifying a deadline. “There is a 40-decibel limit [on the noise the turbines can make], and we have no idea if they’re in the threshold or not.”

To describe what the sound is like, she used Highway 401 versus airplane noise as an example, pointing out that the highway noise is more of a hum, and when she lived near it, the sounds did not bother her at all.
However, the turbines produce something more in line with the “drone of an airplane that goes into your head,” she said. “It’s a deeper tone, and that’s where you get the disturbance of sleep.”

Explaining the noise and its effects on her is not easy, she said, but it is similar to the sensation people get in their chest when listening to bass guitar.

Disheau said she explained her experiences to MOE’s acoustical engineer, adding that the sensations are at their worst when the blade tips of the turbine across the road (south of Brinston) and the one to the north behind her home (west of Brinston) are facing one another.

“The acoustical engineer said ‘yes, that it all makes sense,’ ” Disheau added. “This is not normal. You should not be in sleep disturbance in your own house.”

Meanwhile, Disheau is the only one in her home experiencing the effects of the rotating blades, as her husband, who shares the second storey bedroom on the home’s vinyl-sided addition, is tone deaf, and her children sleep on the first floor of the brick-sided main house.

The noise-monitoring equipment is controlled by a switch, which has been placed inside Disheau’s home. When she notices the noise, she flips the switch and the machinery calculates and documents the findings.

“Once everything is taken down, the ministry guy goes through [the recordings] and writes his report,” she said, which will list the decibel readings for various weather conditions (wind speed and direction).

When asked what she hopes to accomplish through this procedure, Disheau said the findings could require that EDP shut down operations during specific times of the day or during specific wind conditions should they prove the decibel levels exceed the regulated amount.

People with complaints about excessive noise from the turbines at Brinston must call both the developer, EDP Renewables (1-877-910-3377 ext 3) AND the Ministry of the Environment (1-800-860-2760). 

 

CanWEA execs venture down to Brinston wind ‘farm’

Not from around here: just visiting for the brainwashing

The executives at the wind power developers’ lobby group, the Canadian Wind Energy Association, took a trip down the road from their offices on Carling Avenue in Ottawa to see the wind power project in Brinston, just south and east of Ottawa.

Here’s a report on the visit:

CanWEA Staff Tours South Branch Wind Farm

On June 25, several EDPR employees led a tour of the South Branch wind farm for staff members of the Canadian Wind Energy Association (CanWEA) , including CanWEA’s president, Robert Hornung, who had this to say about the visit: The siting characteristics of South Branch and how well the wind farm blends with the natural landscape are truly impressive, said Mr. Hornung. We were equally impressed by the care and attention that EDPR has taken in building a high level of enduring community acceptance. 
The tour of the wind farm, located near Brinston, Ontario, included stops in the O&M building as well as the inside of the base of a tower and the substation building. After an informative tour, CanWEA expressed interest in working with EDPR to improve its information packages for farmers.  Several CanWEA representatives also said they planned to stop by the upcoming South Branch Kid Wind Day, which will be held on Thursday, July 24, and attended by 150 kids.

The claim that EDP has “enduring community acceptance” would be laughable, were it not for the truth about this community: once the wind project was publicly announced by the original developer, Germany-based Prowind, the community became divided between the few farm owners leasing their land for turbines, and others in the community who had no choice but to watch this happen to them. A community group was organized and held several information meetings…but of course, with the Green Energy Act, there are no solutions through elected representatives. South Dundas Council voted on a resolution to say there would be no support for further wind power development as Ontario doesn’t need any more power generation.

The so-called South Branch Kid Wind Day is NOT for local families (hard for them to miss the huge, 3-megawatt turbines) but it will be for kids being bused in from elsewhere. The community has not even been informed of this PR event.

Of greater concern, though, is the news that an “information package” is being developed for farmers: this is being worked on because Eastern Ontario has a green light from the province for wind power development…it is rumoured that 5,000 more acres in North Dundas have been optioned for future wind power development.

Our question: will EDP and CanWEA provide full disclosure on noise, health problems, sleep disturbance, property value loss, and the potential for lawsuits from neighbouring landowners?
