H.2015 Hearing before Joint Committee on Public Health

June 12, 2019

Time for hearings on Beacon Hill. A health commission to study the effects of industrial wind turbines was one of the bills before the Joint Committee on Public Health on June 11, 2019. H.2015 establishes a commission to investigate and study the incidence and impacts of adverse health effects from land-based wind turbines. It also recommends administrative and legislative changes to mitigate or eliminate adverse health effects from land-based wind turbines.

Sub-audible sound waves sent out as the blades spin past the shaft set up vibration and resonance in our body cavities and fluid-filled spaces – ears, eyeballs, skull, our lungs and bellies. They are the ultimate, inescapable boombox moved in next door.

This is from Helen Parker’s testimony about infrasound low frequency noise (ILFN), which “impacts a significant 10-20%, perhaps 30% of the population.”

Most vulnerable are children, elders, and those who are especially reactive to sensation – those with a prior PTSD, autism, abuse victims, …and many of us whose souls are drawn to more rural rather than urban environments.
Symptoms: nausea, headaches, tinnitus, increased blood pressure, anxiety, difficulty with memory and concentration, and panic attacks which arise when awake or asleep.

David Dardi should know. As he wrote in his testimony:

I have been adversely affected by a wind turbine for the last 7 years and
have been unsuccessful in getting any relief from it’s affects. Several other of my neighbors have also been affected by this wind turbine and are equally as anxious to get relief and to have our situation exposed and studied.

To ask the Joint Committee on Public Health to report H.2015 favorably out of committee send comments to:
–Senate Chairperson Joanne M. Comerford: Jo.Comerford@masenate.gov
–House Chairperson John J. Mahoney: John.Mahoney@mahouse.gov

Representative David Vieira sponsored H.2015 – “Resolve to establish a commission to study the health impacts from land based wind turbines to protect the health of the citizens of the Commonwealth.” Co-sponsors include another Barnstable representative, Sarah Peake, and Cape and Islands representative Julian Cyr.

Ambrose Nudges DEP on FGW Compliance

February 16, 2019

He doesn’t say it in so many words. But with his latest comment to the MassDEP, Stephen Ambrose points out it doesn’t take rocket science to predict that people living near wind turbines will experience excessive noise. He recommends the Department continues investigating the sound study of Plymouth’s Future Generation Wind project.

As if resident complaints weren’t enough, there are also the things left out of the Plymouth Sound Compliance Monitoring Report.

Skepticism is warranted for omitting critical information: 1) wind turbine SCADA files with noise measurements. 2) turbine specifications for electric power output and sound power levels with and w/o NRO. 3) noise model predictions with input parameters and results. 4) noise level vs time history plots showing wind turbine fluctuations. 5) name, title and qualifications for author, reviewer, and approver.

Ambrose said in an earlier message to the DEP, “This review finds FGW exceeds the MassDEP noise policy by 10 to 20 dB at all locations.” His analysis cites the report issued in May 2018 by Waltham-based Tech Environmental.

Turbine Roulette

January 13, 2019
ar-160309648Falmouth is facing a tough decision in its next roll in the wind turbine gamble–move, dismantle, or share. On Monday January 14, 2019, the Selectmen will hear that discussion at 7:45 PM:
 
Discussion and vote on moving, repurposing or dismantling wind turbines. Options to include:
  • a. Wind 2 to alternative Falmouth wastewater site or a site outside of Falmouth
  • b. Wind 1 to a site outside of Falmouth

As Mark Cool reports on his Firetower Wind blog, Falmouth Selectmen to Weigh Relocation Option,

The Falmouth Board of Selectmen intend discussing and voting to potentially relocate a major piece of municipal infrastructure, at an upfront cost to taxpayers of 3 million dollars, while an official zoning classification of the wind turbine structure goes without address or determination.

Wind in the 500 foot Rafters

December 23, 2018

How can the the Plymouth Future Generation Wind turbines be louder when turned off than when they are running? Chris Kapsambelis, trying to figure out the difference, noticed that before the turbines were built, the quiet night time noise ranged from 26.6 to 35.6 decibels (dBA).

Now, according to Tech Environmental noise testing, background noise is 7 to 18 dBA higher in the same locales. What could explain this? Consider the one new element in the cranberry bogs. There are now 4 wind energy plants, with nacelles alone that weigh 26 tons, suspended on 500 foot towers. 

Recently, I wrote about the curious phenomenon, where the wind turbine noise appeared softer than the ambient background, a seemingly impossible condition.

Since then, I have come across evidence that might explain how this is possible…. 

In retrospect, one must conclude that the extra noise with the turbines off, must be generated by the turbines themselves, even though they are turned off.

For more on the mystery, read the explanation Chris Kapsambelis came to.

Bourne finds noise nuisance from Plymouth turbines

October 26, 2018

Two years after Bourne complaints began, the Board of Health has taken action. According to Cape Cod Times reporter Beth Treffeisen, “The board will communicate to the Plymouth Board of Health its determination that the turbines are a nuisance to the residents of Bourne” (Bourne health board declares Plymouth turbines a nuisance” 10/15/18).

“To me, this is a good first step and it will put the ball in the court of the regulating authorities,” said Plymouth resident Larry McGrath. “It is an obvious nuisance that is being ignored by the town of Plymouth and MassDEP. The town of Bourne is bringing light to the two regulating jurisdictions now.”

Speaking for a local group, the Buzzards Bay Action Committee, Ian Davies “told the board that there have been approximately 350 complaints filed with the board of health over the turbines ” (“Bourne Health Board To Press Plymouth Officials, DEP On Turbines” by Michael J . Rausch 10/25/18 in the Bourne Enterprise).

BOS Chair Belittles Noise Complaint

September 14, 2018

Frustration was the order of the day at the open forum period of the September 4, 2018 Board of Selectman meeting in Scituate. David Dardi had another sleepless night to recount. The select board chair felt he had heard it all before.

David Dardi:

This morning when I dragged myself out of bed after a sleepless night, I told myself I would come in here and tell you once again, even though I know you’ve heard it so many times, of the problem that’s out there with that wind turbine for me and my neighbors.

The problem for the board was that the town is starting noise testing, so they felt they were taking reasonable steps. But to anyone listening to the exchange, it sounded like an attempt to muzzle complaints.

Board Chair John Danehey interrupted Dardi’s remarks:

… it’s the same song and dance you sing….  I know you want it all shut down, it doesn’t matter what direction the wind comes from and I know you like coming in here for TV land for 5 minutes to talk to us. Please bring something new to the table.

But the bottom line is, as Dardi concluded, “Anyway, you’ve heard it again, we’re still not sleeping.”

This clip appeared on the Scituate Monthly ~ Our Town, a private facebook page and prompted over 50 comments. The full coverage of the meeting is on Scituate’s cable access channel SCTV on YouTube.

Graphs Contradict the Story

September 7, 2018

Engineer Chris Kapsambelis was scratching his head recently about the Plymouth Sound Compliance Monitoring Report. How, he wondered, could it be possible that the ambient lowest noise level for the cranberry bogs (L90–usually a quiet night time) was right up at the 50 dBA point? The quiet level shown here by a blue line is actually louder than some of the periods when the turbines were operating.

In the Tech Environmental Report, the Appendix Section, I came across this graph, and others like it, which I am having difficulty understanding. The note on the upper left corner states that the increase over ambient is only 0.6 dBA applying the DEP method. The blue line at the center, close to the 50 dBA level is described as the Ambient L90 background sound level with the turbines OFF.

Here is my problem. By casual inspection, the L50 metric, applied to the plot for turbine ON noise, would yield a level close to the L90 Ambient background level. Does that mean that the noise is softer when the turbines are running? Is the noise that falls below the L90 line on the graph inaudible? What kind of instrument is there that can record sound that one cannot hear?

We need to ask the DEP if their method for wind turbine compliance testing yields sensible results.

 For more on L90 and other noise measurements, Kapsambelis explains in his essay Acoustics and Wind Turbine Noise.

Acoustician Stephen Ambrose issued an independent peer review citing numerous problems with the compliance report.
