Report of the Wind Advisory Committee to the Shelburne Falls Planning Board

Author:  Shelburne Falls, Mass., Wind Advisory Committee

Wind Turbine Systems for Premises Use: “Any system of turbines, whether located on the building or the ground, designed primarily to generate heat or electricity for the principal home or business located on the lot; such systems may generate a limited amount of excess electricity for resale to an electrical utility provided the system is designed principally to supply the electrical needs of the home or business on the lot.”

As written, the bylaw requires more detailed and specific interpretations for the Special Permitting Authority (now the Zoning Board of Appeals) to review, accept, or reject specific proposals for premises-use only wind turbine systems.

The WAC has been tasked by the PB to develop factual and educational material upon which it can draw when developing a more detailed premises use only bylaw. This Report summarizes that factual and educational material. When useful, the Report cites and paraphrases scientific research articles, research reported on web sites, investigations made by committee members and anecdotal evidence. Where useful, the Report makes recommendations to the PB, based upon the information that it has gathered and analyzed.

Response to NHMRC Systematic Review and Draft Information Statement concerning wind turbines and adverse health effects

Author:  Waubra Foundation

The NHMRC have not invited public comments on the Systematic Literature Review, however as this document forms the basis for the NHMRC Draft Information Statement, the Foundation has looked at the Systematic Literature Review document closely and found serious cause for concern. Those concerns are outlined below.

We note that the document has been peer reviewed, however no details have been provided about the identity or qualifications of the Canadian Peer Reviewers, in particular their expertise and knowledge in the field of environmental noise, clinical medicine, acoustics, or research in related areas, and possible conflicts of interest, both disclosed and undisclosed.

That may explain why these issues were not detected earlier. ...

Concluding remarks

What the 2014 NHMRC Systematic Review has clearly done is acknowledge that sleep disturbance, annoyance and reduced quality of life are confirmed by the data which was allowed to be included in the systematic literature review.

The Review has also highlighted the lack of objective evidence containing both full spectrum acoustic measurements and concurrent objective physiological data including sleep (EEG), blood pressure, heart rate and biochemical markers of physiological stress, such as cortisol conducted inside the homes of people reporting the new symptoms. No such studies have ever been conducted.

This sort of research in the homes of people reporting the new sleep and health problems, as well as in the laboratory was recommended “as a priority” in June 2011 by the Senate Inquiry chaired by Greens Senator Rachel Siewert. The research is long overdue, and it is pleasing that the current Federal Coalition government have committed to ensure it is conducted.

However, with respect to the Systematic Literature Review document, because of the serious issues raised above about the decisions made by NHMRC Literature Review Panel Members and the Systematic Literature Team members to

there are unfortunate consequences for the integrity of the document, and for the professional reputations of all those involved in its production.

Any Draft Information Statement prepared by the NHMRC on the basis of this dangerously incomplete Systematic Literature Review will be similarly dangerously incomplete and misleading, and governments who rely on it will not be getting the most accurate and up to date independent scientific advice they need to properly protect the health of their citizens, which they have an obligation to do.

The consequences for the residents who are suffering so greatly resulting from systemic regulatory failure of wind turbine and other environmental noise pollution are predictable serious adverse health effects, chronic exhaustion, and home abandonment.

The current situation is a national and international disgrace, and it brings considerable shame on those health and acoustics professionals who are involved in hiding the truth from government, from colleagues, and from fellow citizens.

“New” studies since 28 September 2012

  • Mechanistic evidence (evidence of mechanisms)
  • Direct causation evidence – wind turbine noise
  • Parallel evidence (other noise sources)

Comparison of wind turbine acoustic measurements and analysis, resident responses and wind farm power output during on-off testing at a South Australian wind farm

Author:  Morris, Mary

Summary: In this report, noise diary complaints recorded by local residents were compared with EPA measured low frequency and audible noise inside a home near the Waterloo wind farm, on the same evening as a deliberate shutdown of the turbines. Sleep disturbance, excessive noise and annoyance complaints coincide with measured elevated levels of low frequency noise (LFN) and audible noise inside the home. It can be seen that when the wind farm was turned off and then on again, “C” weighted, Unweighted and LAeq(LF) levels fell and rose around 10dB. This suggests that the wind farm is making a significant LFN contribution to local environment. The change in “A”weighted levels as a result of the shutdown was not significant, suggesting that “A” weighted levels do not accurately reflect the impact of the turbines on the residents.

Location and population description

The Waterloo wind development commenced operating in October 2010 and comprises 37 Vestas V90 wind turbines in a 17 km line along a North South ridge line in the Mt Lofty Ranges of South Australia.

The Waterloo area is home to a mixed farming community in the Clare and Gilbert Valleys Council area in the Mid North of South Australia. A significant proportion of the population are long term farming families involved with Primary Production and related support industries. Retirees, pensioners, working families, tree changers, lifestyle block owners and weekenders also make up the local community as they are attracted by the amenity provided by the rural setting, hills and ranges, native fauna, creeks and natural vegetation of the local environment. Regional Development Australia stated in August 2010 that the population of the local Council area of Clare was “rising as a result of interest from retirees and people seeking a different pace of life.” (1)

There are approximately 75 houses within 5 km of the turbines and approximately 230 houses within 10 km. The township zone of Waterloo is comprised of 19 habitable houses and is located approximately 3.2 km West of the turbines.

Nature of complaints/impacts

Three township houses and one farmhouse (4.5 km west of the turbines) have been vacated because of effects attributed by residents to the wind farm – particularly sleep disturbance and physiological symptoms (pers comm).

One habitable house with 11 turbines within 2 km has remained vacant for more than 2 years since the death of the elderly owner. (2)

The Waterloo wind development has been the subject of a large number of complaints from residents up to 10 km from the turbines. The majority of complaints relate to NOISE, VIBRATION, SLEEP DEPRIVATION and HEALTH EFFECTS. In all, 4 Homes have been abandoned and many residents have to regularly “get away” in order to get adequate sleep and recover. (2)(3)(4)

EPA involvement

In April to June 2013, the South Australian Environment Protection Authority (EPA) conducted a 10 week study into wind farm noise at 6 homes near Waterloo wind farm. (5)(6)

The EPA study was instigated in response to ongoing noise, vibration, sleep disturbance and physiological symptom complaints, including home abandonments. Residents living up to 10 km away from the wind farm have complained about adverse impacts and cite the wind farm as the source of their disturbance. (2)(3)(4).

During the 10 week period, the EPA collected noise data at 6 sites between 1.3 and 8 km from the turbines. 28 households volunteered to keep noise diaries on forms supplied by the EPA, which the SA EPA then used to help them focus their analysis on specific events.

Only noise diary entries reporting audible noise and vibration were taken into consideration by the SA EPA as this was not intended to be a health study. (4)(5)

Residents’ reports of awakenings, poor sleep, symptoms and sensations have been disregarded by the EPA as indicators of noise emissions experienced by the residents.

As part of the study which commenced on 8 April 2013, the SA EPA conducted 6 shutdowns (on-off testing) on 1st and 30th May and 5th, 10th, 12th & 14th June to determine what contribution, if any, the wind farm was making to the local noise environment.

Turbines were turned off a for a period of around 50 minutes for each shutdown.

Acoustic measurements for before, during and after each shutdown are available in graphs found on the EPA’s website report. The majority of the EPA report of their Waterloo study is available as a pdf at the following link: http://www.epa.sa.gov.au/xstd_files/Noise/Report/Waterloo_wind_farm_report.pdf. (Note, at the time of writing, on this link, the shutdown dates are incorrect in the pdf – the last 4 shutdowns were in June, not May as listed in Table 1 of the pdf.)

Individual components of the EPA report, including weekly noise level graphs for each site and noise diary summaries are available as a series of separate webpages and can be downloaded at: http://www.epa.sa.gov.au/environmental_info/noise/wind_farms/waterloo_wind_farm_environmental_noise_study

Comparison of residents noise diary entry complaints with EPA acoustic analysis

The author of this comparison has been provided with 17 of the 28 diaries by residents and has been able to compare the residents perceptions with the EPA’s acoustic analysis.

Looking at diary entries for both audible and inaudible events reveal that there is a significant impact from the wind farm on the residents and that events described by the residents coincide with times when the EPA’s measurements show elevated levels of Low Frequency Noise.

This comparison paper focuses on Shutdown 1, INSIDE the home at the EPA West site. Graphs and tables sourced from the EPA’s Waterloo reports have been used as a basis for the following comparisons and comments. These include:

“Inside West Week 4 Graph”
http://www.epa.sa.gov.au/xstd_files/Noise/Other/West_Graph_wk4.xls

“Audio record analysis for the West site: Tables 36 and 37” (event 31)
http://www.epa.sa.gov.au/xstd_files/Noise/Other/waterloo_app_f.pdf

Event 31 in Tables 36 and 37 corresponds to the period of time before, during and after Shutdown 1 on 1st May 2013.

All Waterloo turbines were shut-down for a 50 minute period from 20:10 to 21:00 Central Australian Standard Time (CAST). Noise diary entries obtained from 2 study participants: the West site resident (W) and a neighbour (N), have also been compared with the EPA report. (extracts appear in the following)

At this time of the day, the West residents are home and watching tv in the lounge room. The EPA’s single microphone is in a spare bedroom with the door and window shut. The West residence is approximately 2.5 km from nearest WTG.

At the Neighbour home, coinciding with the shutdown, it is bedtime for the 3 small children and the parents are watching tv. N is approximately 4 km from the turbines.

NOISE EVENT 31 starts 18:00 1st May 2013 – same evening as on-off testing

The SA EPA noise graph for Shutdown 1 INSIDE the WEST home (see Figure 1) shows that:

  1. When the turbines were switched off, the Unweighted, C-weighted and LAeq(LF) noise levels dropped approximately 10 dB.
  2. When the turbines resumed operation, these 3 noise levels rose to their pre-shutdown levels as wind conditions were similar to the pre-shutdown period.
  3. The change in the A-weighted level was not significant, confirming that A-weighted measurements may not be a good indicator of the sound energy levels which are disturbing the residents.

The EPA Record Analysis for this period shows:

EPA somehow concludes: no significant noise impact, wind farm is compliant, no review of the guidelines in warranted.

Morris-fig5
Morris-fig6

Conclusions

Shut down 1 at WEST showed that the EPA’s conclusion (that the wind farm does not create an adverse noise impact at this home) is not supported by their own data or by the residents diary entries.

“A” weighted values may not accurately reflect the impact of the turbines on the residents.

Operation of the wind farm contributed around 10dB of low frequency noise to the local environment.

Limiting compliance assessment to audible parameters does not satisfactorily address the significant impacts caused by LFN from wind turbines.

Consideration should be given to qualitative as well as quantitative assessment.

Acoustic analysis of INSIDE measurements, immediately before and after Shutdown 1, show values which exceed SA EPA noise guidelines.

The EPA could not hear wind farm noise (which was disturbing the residents) on their audio recordings, calling into question the merit of this methodology.

Noise limits recommended by DEFRA, the Danish authorities and Dr Norm Broner (60dB(C))
were exceeded on May 1st 2013.
