Resolution # 03212013-B
On March 21, 2013 The Mercer County Township Association has adopted the following resolution:
Whereas, the Mercer County Township Trustees Association is concerned that the development of industrial-sized wind generating power plant in populated areas like ours can have many long-term negative consequences, that at this time, we cannot fully quantify and understand.
Whereas a large industrial wind development can have many potential short and long term negative impacts to both the local road system as well as to economic development opportunities.
Whereas, this Township Trustees Association respects and recognizes the importance of private property rights but recommends that landowners be fully informed and seek professional legal counsel that is versed in the law as it relates to the granting of leases, easements to wind development companies. Further we respectfully request that landowners consider potential impacts to neighbors as a result of agreements being formalized with wind development companies.
Finally, it is not the intent of this Township Association to promote large industrial wind development efforts in Mercer County, but rather to discourage them. This resolution does not in any way discourage private entities from developing wind resources under the 5 megawatts threshold (which is not regulated by the Ohio Power Siting Board) provided they comply with applicable zoning regulations.

Two wind turbines towering above the Cape Cod community of Falmouth, Mass., were intended to produce green energy and savings — but they’ve created angst and division, and may now be removed at a high cost as neighbors complain of noise and illness.
“It gets to be jet-engine loud,” said Falmouth resident Neil Andersen. He and his wife Betsy live just a quarter mile from one of the turbines. They say the impact on their health has been devastating. They’re suffering headaches, dizziness and sleep deprivation and often seek to escape the property where they’ve lived for more than 20 years.
“Every time the blade has a downward motion it gives off a tremendous energy, gives off a pulse,” said Andersen. “And that pulse, it gets into your tubular organs, chest cavity, mimics a heartbeat, gives you headaches. It’s extremely disturbing and it gets to the point where you have to leave.”
The first turbine went up in 2010 and by the time both were in place on the industrial site of the town’s water treatment facility, the price was $10 million. Town officials say taking them down will cost an estimated $5 million to $15 million, but that is just what Falmouth’s five selectmen have decided to move toward doing.
“The selectmen unanimously voted to remove them. We think it’s the right thing to do, absolutely,” Selectman David Braga said. “You can’t put a monetary value on people’s health and that’s what’s happened here. A lot of people are sick because of these.”

ROCKFORD – Nearly 50 residents attended a meeting held Tuesday by a group opposing wind turbines in northern Mercer County. Most at the meeting simply asked questions.
Neighbors United co-chair Pete Hayes told the crowd at least 17 land leases have been signed in the Rockford area to construct turbines. The turbines would be an extension of the proposed Long Prairie Wind Farm in Van Wert County.
Van Wert resident Ron Schumm, whose neighbors have turbines, said the turbine company tore up the roads and did not adequately repair them.
“They will destroy your roads,” he said. “That’s something the county and townships should be aware of.”
Residents asked about the flicker and noise produced by the 300-foot-tall structures. Schumm said the first time he saw the flicker – the shadow cast by the turbine’s moving arms – he didn’t know what it was. The nearest turbine to his house is a quarter mile away. Schumm said he only sees flicker in his house for about one week out of the year when the sun is rising.
“If the turbine was located somewhere else, that would be a different story,” he said.
He also said the noise from the moving arms produces a thumping sound, but he only hears it when his windows are open.
“My wife has allergies so we don’t have our windows open very often,” he said.
He also urged residents to hire an attorney to review any contract. Schumm said he considered allowing a turbine on his land but then changed his mind.
Businesses will always write a contract to suit themselves more than the resident, he cautioned.
“No offense to local attorneys, but they just don’t have the background to handle this,” he said. “We hired an attorney from Columbus, and they are expensive.”
Schumm said a pro is the money made on the venture but cautioned that people should be weary of what is happening to farmland.
Each turbine uses about 1-2 acres of land, for which the farmer receives a payment, and the farmer does not have to pay property tax on that land. That land cannot be farmed. Wind companies also pay neighbors without turbines a certain amount of money “for their inconvenience,” he said.
“What will we do in 2050 when turbines take over our farmland?” he said. “We can live without wind energy. We can’t live without food.”
Residents asked if the turbines would run often enough to make the project worth it. Schumm said they move with very little wind.
“It’s amazing how little wind on the ground it takes to get those things moving,” he said. “They’re going almost all the time.”
Schumm said the turbines do allow him to tell which direction the wind is moving and how fast.
Residents also asked if the turbines bring down property value and if the contract covers who is responsible for dismantling the structures after they break down or become obsolete. Schumm answered it’s too soon to know.
He believes property values would decrease and said the contracts he’s seen say the company is responsible for removing broken down turbines.
“My biggest concern is bankruptcy,” he said. “Who’s going to make a bankrupt company tear it down?”
Schumm said he tried but failed to negotiate an upfront payment from the company to cover costs if they go bankrupt.
“I think that’s something elected officials will have to do,” he said.
Hayes provided attendees with letters addressed to Mercer County Commissioners, Gov. John Kasich and local congressmen saying they are against the development of turbines.
The proposed Long Prairie Wind Farm involves the construction of a 200-megawatt wind farm – approximately 67 turbines — south of the city of Van Wert, business developer Roger Brown has said. He said as many as five turbines would be constructed in Mercer County.
Brown also has asked commissioners for a payment in lieu of taxes for the project. Commissioner Jerry Laffin last week said they would not accept the proposal unless they entered into negotiations with the company and first talked with those affected.
Neighbors United also has asked Rockford, Mendon and Willshire councils to consider banning turbines inside the corporation limits.
Neighbors United will hold an educational night at 7:30 p.m. Feb. 26 at the village hall. Council will meet for its next regular meeting at 7:30 p.m. Tuesday at the village hall.

When it comes to wind farms, it may be the sound you can’t hear that drives you to distraction, according to a report released this week that is pitting environmental groups against one another.
The study of noise levels around the Shirley Wind Farm in Brown County detected largely inaudible, low-frequency sound inside three nearby houses. But researchers found that only in the home closest to the turbines could it be correlated with sound coming from outside the house, according to the report released Monday.
The study concluded that between the low-frequency sound and the nausea, dizziness, headaches, ear pressure and other maladies reported by neighbors “enough evidence and hypotheses have been given herein to classify (low-frequency noise) as a serious issue, possibly affecting the future of the industry.”
But the study could not conclude that the health problems reported by nearby residents were caused by the low-frequency sound from the eight-turbine project, according to Clean Wisconsin, a Madison environmental group that arranged the testing.
That’s because “there aren’t any documented peer-reviewed studies finding any health effects for inaudible sounds,” said Tyson Cook, staff scientist for Clean Wisconsin, which favors development of renewable energy.
Duke Energy of Charlotte, N.C., which owns the Shirley Wind Farm, was reviewing the study but had no comment Thursday, spokesman Jason Walls said. Walls added that the facility was “in compliance with all laws and ordinances.”
The study was paid for in part with funds awarded by the Public Service Commission to Clean Wisconsin and Forest Voice, a group of homeowners fighting the Highland Wind Farm, a proposed 41-turbine facility in St. Croix County. Both groups have been granted intervenor status in the Highland Wind Farm case before the PSC.
Two lawmakers and another group involved with the testing say the study could be groundbreaking.
“The report suggests that very low-frequency noise from wind turbines may cause motion sickness-like symptoms in some people,” according to a statement from Forest Voice.

The roar over wind turbines
Jan 10
Doreen Reilly said her family can’t sleep at night because the wind turbine less than 1,000 feet away sounds like a “jet liner hovering” over her Kingston home. During the day, Reilly said, she gets headaches because the spinning blades from the 400-foot-tall structure cause sunlight to flash like “a strobe light” throughout her home.
“You can’t escape it,” said the Leland Road resident. “I’m very concerned for my family and their health.”
A few streets over, on Copper Beech Drive, David Kennedy said his wife gets headaches from the moving shadows inside their home, and their children have trouble concentrating when this flickering occurs. In November, he filed five complaints with the Kingston Board of Health.
Amid a nationwide push toward wind power and other “green” energy sources, Reilly, Kennedy, and others in towns such as Scituate, Fairhaven, and Falmouth are among a small but growing number of people voicing concerns about wind turbines.
They worry about the long-term health effects of living so close to the machines, and question whether they belong in densely populated neighborhoods. Some say they’ve experienced sleep loss, migraine headaches, ringing ears, and increased blood pressure since wind turbines were installed near their homes.
Such complaints have often been met skeptically by wind-power advocates and the public at large, many of whom assume the complaints of noise, vibrations, and moving shadows are being exaggerated by a gaggle of NIMBYs.

Additional Hazards Identified Regarding Emergency Response and Consequences of Wind Turbine Failure

Additional hazards identified in the following article regarding emergency response and consequences of wind turbine failure.
3 wind-turbine failures firefighters must know
Wind-farms have been around for several decades in Europe, but only in recent years have we seen them appear in the United States. The United Kingdom has experienced a dramatic increase in wind-turbine incidents resulting in a number of civilian injuries and deaths in the past decade, according to a report by Caithness Windfarm Information Forum 2012.
As more communities are using wind energy, many fire departments likewise across the United States are seeing wind-farms being built within their response areas. And as with most new advances in technology new challenges also arise for the fire service.
According to the trade group, American Wind Energy Association, there are utility-scale wind turbines in 38 states, 14 of those states generate at least 1,000 megawatts of power. And growth in this industry seems likely.
AWEA reports that U.S. wind turbines generate 48,600 megawatts; the on-shore potential is estimated at 10.4 million megawatts. To narrow that gap, there are nearly 100 projects in 31 states and Puerto Rico to add wind-generated capacity.
To increase their situational awareness regarding this growing trend, firefighters need to understand the top three types of wind-turbine failures. It is equally important to know the life-safety guidelines to consider when facing this new challenge.
Blade Failure
Blade failure is by far the most common type of failure and is responsible for most of the incidents reported by the CWIF. Blade failure can occur when the blades are damaged such as the result of bird strikes, storm damage, or a runaway/over-speed turbine motor with brake failure.Fire
The second most common incident is the result of fire. Fires can occur from a number of sources, however, mechanical gearbox failure has plagued the industry for years. Other fire causes include electrical malfunctions and lightning strikes.Structural failure of tower
While considered to be the least common type of failure, tower failure can occur from damage during transport, high winds, blade strike or lack of maintenance. A fire originating in the motor housing can spread to the composite fiber blades, and into the structural tower resulting in collapse. Blade strike is believed to be the cause of a tower collapse that occurred recently near Weatherford, Okla.Firefighter life safety considerations
The obvious challenge facing firefighters is the height involved if a fire occurs in the turbine motor. Towers can extend 300 to 400 feet above ground.However, due to the risk of falling fire debris over a wide area, approaching a burning turbine is usually not an option unless there is a life risk involved. If the turbine is turning, power is being generated and an electrocution hazard will be present.
Typically, a good option for firefighters to consider is to evacuate any endangered areas, set up a collapse zone, and attempt to control any ground fires to prevent the fire from spreading to other units.
In the case of a runaway or over-speed event, rotating turbines can throw debris thousands of feet away during a blade failure. Pieces of blades have been documented as traveling over 4,200 feet. Distance and time will fix this problem. Pre-incident planning and SOP development are keys to success for safely handling this unique danger.

An Ohio wind farm is temporarily shut down following severe damage to one of the turbines.
The wind farm, Timber Road II, sits in Ohio just beyond the Indiana state line between Edgerton, Indiana, and Payne, Ohio.
Around 12:45 Tuesday (April 24th) afternoon, two blades on a turbine were damaged so severely that debris was sent raining down on the field below. No one was injured.
The owners, EDP Renewables, say while the investigation into what damaged the blades is ongoing, at this point it doesn’t appear that strong winds were a factor.
A spokesperson for EDP tells Indiana’s NewsCenter that all 55 of the wind farm’s turbines were immediately shut down following the incident. Some were turned back on Wednesday as part of the investigation, but officials say it’s unclear how long that investigation will take.
Robert Silliman of Antwerp, Ohio, was out taking pictures of the broken turbine on Wednesday. He says,”I saw this wreckage scattered quite a ways across the field and I was very surprised that it had gone that far. Of course, we had high winds yesterday.”
EDP officials say each turbine is roughly worth $3million, but this turbine is still under warranty by the manufacturer, Vestas. They say Vestas is conducting their own root cause analysis, and is taking every step necessary to make sure similar problems don’t arise in the future.

Acoustics
This study was conducted at a representative neighbor’s home in Falmouth and confirmed that there are dynamically modulated low frequency acoustic amplitudes and tones produced by the nearby wind turbine.
Dynamic amplitude modulations occurred at 1.4 second intervals that were consistent with the blades rotating past the wind turbine tower (the blade pass rate).
Dynamic amplitude modulations below 10 Hz were stronger indoors than outdoors. Modulations measured indoors were 0.2 Pascal peak to peak, consisting mostly of energy below 20 Hz. Two tones were detected from both the NOTUS and the WIND 1 turbines, at 22.9 Hz and 129 Hz, and are considered signatures of the wind turbines’ acoustic profile.
Outdoors, the A-weighted sound level decreased at a predictable rate of 6 dB per doubling of distance from the nearest turbine.
The linear unweighted sound level decreased according to cylindrical spreading at 3 dB per doubling of distance and was controlled by acoustic energy below 20 Hertz. A-weighting does not reveal this low-frequency information. Sound-level averaging with Leq for any time length hides the low-frequency dynamic amplitude modulations.
Health effects
The investigators were surprised to experience the same adverse health symptoms described by neighbors living at this house and near other large industrial wind turbine sites.
The onset of adverse health effects was swift, within twenty minutes, and persisted for some time after leaving the study area. The dBA and dBC levels and modulations did not correlate to the health effects experienced. However, the strength and modulation of the un-weighted and dBG-weighted levels increased indoors, consistent with worsened health effects experienced indoors.
The dBG weighted level appeared to be controlled by in-flow turbulence and exceeded physiological thresholds for response to low-frequency and infrasonic acoustic energy as theorized by Salt.
The wind turbine tone at 22.9 Hz was not audible, yet the modulated amplitudes regularly exceeded vestibular detection thresholds. The 22.9 Hz tone lies in the brain’s “high Beta” wave range (associated with alert state, anxiety, and “fight or flight” stress reactions). The brain’s frequency following response (FFR) could be involved in maintaining an alert state during sleeping hours, which could lead to health effects.
Sleep was disturbed during the study when the wind turbine operated with hub height wind speeds above 10 m/s.
It took about a week to recover from the adverse health effects experienced during the study, with lingering recurring nausea and vertigo for almost seven weeks for one of the investigators.
