Re: Wind Turbine Health Impact Study: Report of Independent Expert Panel

Source:  Krogh, Carmen

The purpose of this letter is to respond to the Wind Turbine Health Impact Study: Report of Independent Expert Panel of January 2012 that was prepared for the Massachusetts Department of Environmental Protection, Massachusetts Department of Public Health.

I would like to share excerpts from Ontario, Canada experiences regarding the serious risks to health that can occur when industrial wind turbines are sited in close proximity to residents.

As background, I have held senior executive positions at a teaching hospital, a professional organization and Health Canada (PMRA). I am a former Director of Publications and Editor in Chief of the Compendium of Pharmaceuticals and Specialties (CPS), the book used by physicians, nurses, and health professionals for prescribing information in Canada.

Contact with those experiencing adverse health effects which correlated with the onset of industrial wind turbine operations, inspired my research on the topic.

I volunteer my time and expenses, self support research and other activities such as education regarding the science related to wind turbine health effects. Some of my activities include meeting with authorities, locally, provincially and federally.

A colleague and I initiated a self reporting health survey in March 2009. WindVOiCe (Wind Vigilance for Ontario Communities) follows the principles for Health Canada’s Canada Vigilance Programs for self reporting suspected adverse events for prescription and consumer products, vaccines and other. The results of this research have been published in a special edition of a peer reviewed scientific journal. [1]

I have also researched societal impacts relating to this topic. This article has also been published in a peer reviewed journal. [2]

Based on several years of investigation: “My research demonstrates that IWTs were initially welcomed into communities. The reported adverse impacts were unexpected …” and “In addition to physiological and psychological symptoms there are individuals reporting adverse impacts, including reduced well-being, degraded living conditions, and adverse societal and economic impacts. These adverse impacts culminate in expressions of a loss of fairness and social justice.” [3]

Several months after the publication of my article, Shepherd et al noted:

“… wind turbines were initially welcomed by many communities due to their environmental credentials …”

“… residents living within 2 km of a turbine installation reporting lower overall quality of life, physical quality of life, and environmental quality of life. Those exposed to turbine noise also reported significantly lower sleep quality …” [4]

Quality of life and social well being are important health considerations. I have found the stressors occurring within the home and community environment as the result of a change in the environment, e.g. industrial wind turbines, are contributing to adverse health effects. To date, there is no mitigation available to those suffering.

There is ample evidence regarding the health risks associated with industrial wind turbines.

In 2009 The American Wind Energy Association and Canadian Wind Energy Association funded experts to conduct a literature review which explicitly identifies a causal link (through annoyance) to the reported adverse health effects.

The authors of the industry convened report determined the documented “wind turbine syndrome“ symptoms (sleep disturbance, headache, tinnitus, ear pressure, dizziness, vertigo, nausea, visual blurring, tachycardia, irritability, problems with concentration and memory, and panic episodes associated with sensations of internal pulsation or quivering when awake or asleep are symptoms) “are not new and have been published previously in the context of “annoyance”” and are the “well-known stress effects of exposure to noise”. [5]

This acknowledgement cannot be ignored.

Peer reviewed studies consistently acknowledge wind turbine noise is perceived to be more annoying than transportation noise or industrial noise at comparable sound pressure levels. [6]

Now that the experts funded by members of the wind industry have identified a causal link steps must be taken to ensure these health outcomes are avoided.

Three of the authors of this industry report testified at an Ontario Environmental Review Tribunal which was conducted under oath. 26 expert witnesses from around the world testified (10 Appellants, 16 Respondents – Ministry of Environment and Suncor Inc developer). The evidence and testimony of this tribunal is further evidence that wind turbines can harm human health.

An Ontario Freedom of Information request and peer reviewed articles published during 2011 should also be considered.

I have attached legal opinions and citations regarding the evidence including a summary which I presented to the Standing Senate Committee on Energy, the Environment and Natural Resources, October 18, 2011.

The Ontario Environmental Review Tribunal Decision, July 18, 2011, stated:

“This case has successfully shown that the debate should not be simplified to one about whether wind turbines can cause harm to humans. The evidence presented to the Tribunal demonstrates that they can, if facilities are placed too close to residents. The debate has now evolved to one of degree.” [7]

A Freedom of Information request from the Ontario Ministry of Environment notes:

“It appears compliance with the minimum setbacks and the noise study approach currently being used to approve the siting of WTGs will result or likely result in adverse effects …” [MOE memorandum, Ontario Senior Environmental Officer, April 9, 2010]

The Ontario Ministry of Environment documents are available at www.windyleaks.com

I note that the Wind Turbine Sound and Health Effects – An Expert Panel Review – December 2009 states that: wind turbine sound/noise may cause annoyance (p. 5-3), stress (p. 4-3, 4-10) and sleep disturbance (p. 4-3), which may have other consequences (p. 4-3, 4-10) [8] Annoyance may seem of little consequence in everyday language; however, in clinical terms it has negative health consequences. The term annoyance is acknowledged as an adverse health effect.

The indirect pathway is often given a low priority regarding this topic. The Environmental Review Tribunal expressed concerns with respect to The Potential Health Impact of Wind Turbines (Chief Medical Officer of Health (CMOH) Ontario Report) – May 2010.

“… about the Director’s apparent lack of consideration of indirect health effects and the need for further work on the MOE’s practice of precaution …” [9]

To better understand the importance of the indirect pathway, please note the World Health Organization noise schema below. Symptoms being reported are through the indirect pathway. Testimony under oath during the Environmental Review Tribunal acknowledged that the indirect pathway was not considered by the CMOH. [10]

Statements indicating there is no evidence of a “direct” causal link may be accurate but is also an incomplete assessment of the health risks. The indirect pathway of noise annoyance, sleep disturbance and stress leads to consequences (cardiac). When one focuses on “direct” effect one omits consideration of an equally significant part of the health equation ie indirect effects.

Some have referenced that World Health Organization Noise Guidelines (2009) recommend a 40 dB noise level for industrial wind turbines; however, this is an incorrect interpretation of these guidelines. The WHO guidelines are based on road, rail and air craft noise, not on industrial wind turbine noise. Peer reviewed research has shown wind turbine noise is more annoying than these three types of noise at comparable sound levels. Therefore the premise of 40 dB applying to wind turbines is not justified – research [11] and MOE field officer [12] propose 30 to 32 dB.

To conclude, a December 2010 report commissioned by the Ontario Ministry of Environment and submitted as evidence during the Environmental Review Tribunal and just recently released by the Ministry notes:

“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.” [13]

This report also states

“Stress symptoms associated with noise annoyance, and in particular low frequency annoyance, include sleep interference, headaches, poor concentration, mood swings …” [14]

During 2011, there has been significant progress in acknowledging the harm that can occur when industrial wind turbines are sited too close to residents.

Consideration should be given to recent Australian movements towards a minimum 2 km setback (see Senate slides attached for references). Furthermore in January 2012 the National Health and Medical Research Council reaffirmed their position that authorities are instructed to maintain a precautionary approach for this issue.

Social well-being is acknowledged to be a determinant of health: “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” (World Health Organization [WHO], 1948). Many jurisdictions, including the Canadian federal, provincial, and territorial governments and health officials have accepted WHO’s definition of health (Health Canada, 2004, vol. 1, p. 1-1).” [15]

I am not certain whether jurisdictions in the United States of America have accepted the WHO definition; however, it is widely accepted that social, physical and mental health should be evaluated when assessing adverse health effects.

The symptoms have been acknowledged through testimony under oath, and / or disclosure evidence and/or witness statements and through other references as briefly provided in this letter.

There are some research gaps regarding the mechanism and the siting distances and noise levels that will protect human health.

To conclude: “In all cases, noise should be reduced to the lowest level achievable in a particular situation. Where there is a reasonable possibility that public health will be damaged, action should be taken to protect public health without awaiting full scientific proof.” [16]

I believe we are at the stage where public health officials must acknowledge there are some suffering from exposure to industrial wind turbines. Furthermore it is time to move beyond repetitive literature reviews. There is an urgent need to conduct the research to determine the siting parameters including setback distances and noise levels to ensure protection of health.

Wind Turbine Health Impact Study Is Junk Science

Source:  Hartman, Raymond

[Wind Turbine Health Impact Study: Report of Independent Expert Panel, January 2012, prepared for: Massachusetts Department of Environmental Protection, Massachusetts Department of Public Health]

Junk Science: What Is It?

“Junk science is faulty scientific data and analysis used to advance special interests and hidden agendas.”

General Examples

“Government regulators may use junk science to expand their regulatory authority, increase their budgets or advance the political agenda of elected officials.”

“Businesses may use junk science to bad-mouth competitors’ products, make bogus claims about their own products, or to promote political or social change that would increase sales and profits.”

“Politicians may use junk science to curry favor with special interest groups, to be politically correct or to advance their own personal political beliefs.”

Specific Real-World Examples

The Tobacco Research Institute

The “research” was Junk Science.
It was untrue, manipulated and unreliable.
The “research” caused disease and death.

Asbestos Manufacturers

The “research” was Junk Science.
It was untrue, manipulated and unreliable.

Manufacturers of DDT

The original “research” was Junk Science.
It ignored the health and environmental risks of DDT.

The Wind Turbine Health Impact Study Is Junk Science

Deval Patrick sponsored and defends the study which “found no scientific evidence or medical studies to prove that living near a wind turbine has adverse impacts on people’s health, though it acknowledged further study is needed to look at health impacts stemming from ‘annoyance’ for residents who live near turbines.” [State Capitol Briefs, Afternoon Edition, Thursday, January 19, 2012, State House News Service]

The conclusions reached by the study are utterly and profoundly dishonest.

The study is labeled a “Report of Independent Expert Panel.”

The Panel relies primarily on an inexplicably small number (4) of published research papers, out of 100s that are available.

The sizes of the wind turbines studied are quite small.

The data, models and statistical analyses in these papers are flawed, in ways explicitly noted by the Panel.

When present, the model and analysis are wrong.
The studies introduce a multiplicity of other possible factors, all of which interfere with properly analyzing and estimating the impact of the primary factor upon health – turbine noise.

The Panel mentions but ignores the findings of the most recent analysis by the authors of two of their chosen studies (the Swedish studies). This most recent study contradicts the Panel’s conclusions as follows [as noted explicitly by the Panel at page 19]:

This exclusion is unprofessional, unscientific and outright dishonest.
This is Junk Science.

The Panel identifies the preferred type of study – time-series analyses, looking at families and households before and after the industrial turbines are put into operation → “A Before-and-After Study.”

The Panel does admit to finding the following:

The Panel however concludes that there is insufficient evidence that industrial wind turbines will have any effects upon residents near the installation. It states:

Reflect closely on this language.

The Panel’s report and conclusions are JUNK SCIENCE.

What does this mean for Shelburne?

Pragmatic view of a wind turbine noise standard

Source:  Dickinson, Philip

Abstract
New Zealand Standard 6808:2010 Acoustics – Wind farm noise is unique in that it acknowledges, up front under committee representation, that a representative of a university involved in its development does not support the Standard. Since that time a number of papers and presentations have decried this opposition to the Standard without giving the committee member the privilege of comment or reply. This paper is to put the record straight and explain why the Standard is not supported. Wind farms may well be a viable alternative energy source, but the effects of noise immissions on the health of people living within several kilometres of the wind farms is becoming a concern. The noise level from a wind farm may be quite low, but its characteristics compared to that of the normal background sound make it stand out as something quite different. Often the sound is heard more clearly indoors than outside due to its ability to excite room resonances, making it an irritant causing severe loss of sleep and extreme annoyance. New Zealand Standard 6808:2010 closely follows that used in Britain and parts of Europe, even though there are clear indications that the criteria to be met do not fully conform with World Health Organization recommendations, and the method used is likely mathematically, scientifically and ethically wrong. This Standard and similar standards across the world are clearly biased towards cost effective wind farm development, and it appears public health concerns are not being given enough attention.

Why is sharp-limited low-frequency noise extremely annoying?

Source:  Krahé, Detlef

[Introduction] Low-frequency noise (LFN) is sound focused in the frequency range below ~100 Hz. For example, in Germany sound is defined as low frequency if the C- and A-weighted sound pressure level (SPL) differs by more than 20 dB. For a growing number of people LFN is an urgent problem, and many questions remain unanswered: Why does LFN seem to be a greater problem today than in the past? Are people more sensitive? Is LFN increasing?

It can be assumed that LFN was less common in the past, which doesn’t mean that it was quieter. It is difficult to prove, but not improbable, that A-weighting is in part responsible for increasing LFN, because A-weighting attenuates LFN strongly. Therefore, in the endeavor to meet the limits in regulations, which are mostly defined in dB(A), it is easier (meaning in most cases less expensive) to shift resonances of machines to the low-frequency range than to attenuate the vibration or the sound by technical means. In addition, A-weighting is to blame for an underestimation of the annoyance of LFN.

Another reason for increasing LFN may be found in the growing application of all kinds of noise protection, e.g., noise barriers, special windows, etc. All of these measures have a common property: low-frequency waves can pass through, over, or across them more easily than waves in the middle- or even high-frequency range. Therefore, it isn’t impossible that noise protection bears some responsibility for the problem of LFN. As reported by Persson Waye et al. (2003), after measures had been installed against noise coming from outside, people were suddenly hearing LFN from inside the house and were so annoyed that some of them preferred to sleep with open windows despite the resulting high noise level. Di et al. (2005) reported a similar problem.

In searching for an answer to the question of why some people prefer to endure a louder noise with a broader spectrum than LFN at a lower level, few clues are found in the literature. One clue can be found in the detailed LFN report by Leventhall (2003). According to Bryan (1976) referenced there, the annoyance of LFN is determined by edge steepness limiting the spectrum of LFN to higher frequencies in the way, that a steeper edge causes an unacceptable annoyance while a moderately steep edge is acceptable. The core question is: What is the basic cause for all of these reactions?

In Hansen (2007), many contributions dealing with the effects of LFN on people came to the assumption that the special effects of LFN are caused less by the peripheral processing in the outer, middle, and inner ear but more by the subsequent processing in the nervous system. This might explain the direct influence of LFN on mental health [Persson Waye et al. (2001)], which can be found also in physiologic investigations [Persson Waye et al. (2002)].
