Better Plan, Wisconsin

A is for "assume"

near the town of byron, fond du lac county, wisconsin, fall, 2008

"[Industrial wind turbine] noise, on which the ordinance is silent,

was assumed to be captured by the 1000 foot setback"

--Alex DePillis

From the Minutes of the November 4, 1999 Guidelines and Model Ordinance Ad Hoc Subcommittee meeting.

At the time, DePillis was a state worker employed by the Wisconsin Energy Bureau, Department of Administration.

He now works as a wind developer for EcoEnergy LLC

What are the results of this "assumption" about the 1000 foot setback?

Gerry Meyer carried mail in his community for 30 years.

He lives inside the Invenergy Forward Energy wind farm near the town of Byron in Wisconsin's Fond du Lac County. When the turbines went on line near his home in March of 2008, he was surprised by the amount of noise that they made. He began keeping a noise log. (The entire turbine noise log can be downloaded by clicking here)

Let's look at the noise log for September 1, 2008

6:20 AM Loud motor running or humming sound.

7:05 AM I’m hearing turbine #4 in the barn, shop, and at the computer.

[ Turbine #4 is less than 1600 feet from the house]

11:15 AM Wind SW Loud.

4:15 PM Turbine 4 and 6 are making loud jet flying over sounds, ripping the sky apart. It has been loud all day.

9:40 PM This is the loudest night in a long time.

I hear #4, 6, 73, 74a, 3a and and possibly more.

I can hear them at the computer in the front of the house and in the family room in the back of the house with the TV on.

Keep in mind turbine 6 is ¾ mile away. # 73 is 2480’ and 74a 5/8 mile away.

It is very sad our town officials and PSC have allowed this turbine project to affect the health of residents in this area and it will continue in other areas.

11:40 PM I hear turbine jet flying over sound while watching TV in our family room.

This assumption about wind turbine noise made by Alex DePillis and other members of the Model Ordinance Ad Hoc Subcommitee helped the state create guidelines which allowed Chicago-based wind developer Invenergy to site turbines as close as 1000 feet from unwilling participants homes in Fond du Lac and Dodge County.

The result?

Residents in Dodge and Fond du Lac are having trouble sleeping at night due to noise from industrial turbines, and when they want to sell their homes, no one seems interested in buying them.

This photo, taken December 8, 2008 is of a home near the town of Byron that has been on the market for a long time. The price has been reduced but still no offers.

Can you guess why?

Why would the state put so many residents at risk by allowing a committee to set guidelines based on an assumption that a 1000 foot setback would take care of noise problems?

Local governments who recognized the inadequacy of the state's guidelines for siting turbines have created large wind ordinances intended to protect the health and safety of residents. Within the last year, six Wisconsin townships have adopted ordinances with a 2640 foot setback. They didn't just pull that figure out of the air. And they didn't base it on an assumption. So what is it based on?

Here's what we learned from the findings section from the Town of Union's large wind ordinance regarding wind turbine noise.

The complete text of the findings and all documents used to support these findings are cited in the ordinance. (Download the entire Town of Union ordinance by clicking here)

This is just a summary:

The state's current wind turbine noise limit of 50dBA does not adequately protect residents from the adverse health effects associated with large wind turbine noise.

The town of Union limits large wind turbine noise to a maximum of 35dBA or 5dBA over ambient, whichever is lower, in order to protect residents from adverse health effects associated with large wind turbine noise based on the following findings:

Large wind turbines are significant sources of noise, which , if improperly sited, can negatively impact the health of residents, particularly in areas of low ambient noise levels.

Large wind turbines emit two types of noise-- 1) Aerodynamic noise from the blades passing through the air, which can generate broadband noise, tonal noise and low frequency noise; and 2) Mechanical noise from the interaction of the turbine components.

A dBA scale is commonly used to measure audible wind turbine noise.

Low frequency noise from large wind turbines is not adequately measured by the state's use of dBA weighting.

Noise is an annoyance that can negatively impact health, producing negative effects such as sleep disturbance and deprivation, stress, anxiety, and fatigue.

Large wind turbines create a noise annoyance that can hinder physical and mental healing and can cause adverse health effects associated with sleep disturbance and deprivation, psychological distress, stress, anxiety, depression, headaches, fatigue, tinnitus and hypertension.

Wind turbine noise can affect each person differently. Some people are unaffected by wind turbine noise, while others may develop adverse health effects from the same noise.

At low frequencies, wind turbine noise may not be heard but rather is felt as a vibration. Medical research reported complaints from people who felt the noise from large wind turbines, similar to symptoms that can be associated with vibroacoustic disease.

The risk for adverse health effects resulting from noise annoyance such as headaches, stress, anxiety, fatigue, depression, pain and stiffness, and decreased cognitive ability associated with sleep deprivation from wind turbine noise increases with increasing A-weighted sound pressures. According to wind turbine noise studies, few respondents were disturbed in their sleep by wind turbine noise at less than 35dBA. Respondents were increasingly disturbed in their sleep by wind turbine noise greater than 35dBA.

Wind turbine noise greater than 5dBA over ambient increases the risk for health effects because a change of 5dB is clearly noticeable.

Studies show prolonged exposure to wind turbine noise resulted in adverse health effects at sound levels below those from other sources of community noise, such as road traffic noise. Sound generated by wind turbines has particular characteristics and creates a different type of noise having different health impacts than compared to urban, industrial or commercial noise.

Living in a rural environment in comparison with a suburban area increases the risk of residents being impacted by noise from nearby large wind turbines because of the low ambient noise in rural environments. The International Standards Organization recommends community noise limits for rural areas be set at 35dBA during the day, 30 dBA during the evening, and 25dBA at night.

Eye-witnesses living near newly-constructed large wind turbines in the Town of Byron, Fond du Lac County, WI, testified at the public hearing held by the Town of Union Plan Commission that they currently experience adverse health effects from the wind turbine noise such as sleep deprivation and disturbance, headaches, nausea and dizziness. Th noise from the wind turbines in the Town of Byron is greater than 45dBA at their residences and can be heard inside of their houses and outside in their yards.

Two Plan Commissioners from the Town of Union visited the newly constructed wind turbines in the Town of Byron, Fond du Lac County, WI in June 2008 and confirmed the wind turbines were a significant source of noise. One described the quality and intensity of the noise as sounding like a jet airplane. The other spoke with residents, farmers and a sheriff's deputy in the area who all stated that the turbines were noisy. He also took sound measurements from the home of a resident with a turbine less than 1500 feet from his home. The sound measured between 57 to 67 dBA on June 6-7, 2008.

However, experiences vary. Two other plan commissioners visited wind turbine sites. One visited sites in Byron Township, Lincoln Township and Montfort and found that overall, people were satisfied with the turbines. Two issues noted by this Plan commissioner were tensions between landowners profiting from the wind turbines and those landowners who did not, and poor conditions of roads following the installation of the turbines.

The other commissioner visited wind farms in Iowa. He estimated that approximately 60% of the people he spoke with had positive opinions of the wind turbines and approximately 40% of the people he spoke with had negative opinions of wind turbines.

A fifth plan commission member went to a wind farm south of Rockford, IL. No one was available to talk so he walked around the area. It was a nice day, and windy. He noticed that the windows in the homes surrounding the site were all closed and no one was outside. He stated the noise was similar to a plane going overhead. He stood under a tower and did not feel any unease.

While wind developers continue to downplay the trouble with noise from industrial scale wind turbines, the truth keeps making its way to the public. Watch ABC's Charles Gibson with microphone recording the noise from a wind turbine by clicking here (Warning! There may be an ad you have to suffer through to watch this.)

We believe this is one of the first times the actual sound of an industrial-scale wind turbine has been presented to the public. Mr. Gibson calls it "the sound of the future" -- but for people who are living 1100 feet  (350 steps) from wind turbines of this size in Dodge and Fond du Lac counties here in Wisconsin, it's not the sound of the future. It's the sound of sleepless nights, headaches, and miserable days, right now. Today. Tonight.

Below is what September sounded like to a Fond du Lac family living inside of an 86 turbine wind farm which went on line in March of 2008.

I have had a crackling sound in my left ear for about 10 days.
    11:10 PM Wind SE, dba 48.2, dbc 71.3. Loud jet sound from turbines 4 & 6.

September 11

– 6:25 AM Wind SE. 3 knots, 18.3 rpms. Very loud jet flying over sound filling the air  rom the South, West and North. Yesterday I had slight headache most of the day. I was  working outside most of the day. I rarely get headaches. This morning when I woke up I thought about the buzzing or crackling in my ear for the past week. Is it from the constant turbine noise? I also am concerned about being tired most of the time and not having much ambition. I could take a nap at any time and often do. I see customers that were on my mail route just 6 weeks ago and can not remember their names. This is not just occasionally, but everyday and with people I know. I wonder if I am getting Alzheimer’s disease early or is it turbine sound related? I am 59.
    3:15 PM. Wind SE. I just got home from Madison. Turbine 4& 6 and 73 are giving off loud, ripping the sky apart [noise] even over the rain. About 14 of the turbines  on the West edge of the project are not turning.

    turbine 4.. and I can also hear turbine 6.
    1:20 PM. Wind NW, 6 knots, cloudy, 11 rpms. Low  hum.
    4:00 PM Most turbines are not turning. It is so peaceful picking the raspberries and being able to hear the bees buzzing with out the sounds of the industrial wind turbines.

    September 16 –

    6:20 AM Wind SW, 4 knots, feels calm, 14.6 rpms, dba 44.6, dbc 61.4. Loud motor running or humming sound. I’m hearing turbine 4 in the barn shop and at the computer at 7:05
    11:15 AM Wind SW loud, dba 47.1, dbc 64.7.
    4:15 PM Wind SW, 11 knots, dba 47.3, dbc 67.2, 18 rpms. Turbine 4 and 6 are making loud jet flying over sounds, ripping the sky apart. It has been loud all day.

I hear #4, 6, 73, 74a, 3a and and possibly more. I can hear them at the computer in the front of the house  and in the family room in the back of the house with the TV on. Keep in mind turbine 6 is ¾
    mile, # 73 is 2480’ and 74a 5/8 mile away. It is very sad our town officials and PSC have allowed this turbine project to affect the health of residents in this area and it will continue in other areas.
    11:40 PM I hear turbine jet flying over sound while watching TV in our family room☹

September 17 –

    4:30 AM Wind SW, 5 knots, dba 47.4, dbc 62.3. Jet sound from turbine 4 and 6. Last  night I slept very little due to the constant sound in the house. This is the worst since they began turning on March 3, 2008. I could hear a low like whoosh sound or at times the house seemed to be vibrating. I am getting more angry at elected officials for allowing this to happen
 and that something (turbines) that are 28-30% efficient are even promoted. This is an unjust  use of our tax dollars. I hear turbine sounds as I write this at the computer.
    5:05 PM Wind N, 1 rpms. Fairly calm. Not much noise compared to yesterday.
    10:30 PM Wind N. Noise Is Covered by sweet corn harvesting machinery at the neighbors.

September 18 –

    6:45 AM Wind S, 5 knots, 18 rpms, house dba 51.3, dbc 69.9, front dba 49.9, dbc 65.4. The sound outside is loud. The environmental impact statement for this project and Invenergy company officials say with the new technology you only hear the sound from oneside of the turbine. This is not true. I hear turbine 4, 1560’ to the north and turbine 73, 2480’ to
the south both ripping the sky apart this morning. I hear turbine noise as I write this at the computer. Yes, in the house, Very irritating.
    7:50 PM Wind SW, 18 rpms, dba 49.0, dbc 62.1.It has been loud all day. I’m sure there will be sleep problems tonight.            11:45 PM Wind SW, 9 knots. I can hear turbines 4 and 73 loudest and 74a and 6. I was watching TV and when there
    was no talking I could hear the whoosh, whoosh of the turbines☹ Our son was down complaining and with a recording he had made of the sounds of the turbines he can hear from his room.
It is 11:55 PM and I can still hear him awake. I can hear the turbines at the computer.

September 20 –

    7:20 AM Wind SW, 8 knots, but seems calm, 15 rpms, dba 44.1, dbc 60.6, clear sky.The sound is fairly quiet other than whooshing and humming of the turbines (this is not the pleasant sound like someone humming to music).
    7;35 PM Wind SW, 9 knots, seems calm, 11.6 rpms. I can hear the sound of turbine 4 but no sound reading as the farmer 300 yards down the hill began corn chopping and silo filling so sound reading. It would not be fair to take a sound reading with tractors and choppers running so close by.
    8:20 PM Wind SW, calm, 11 rpms, low hum.

September 21 –

Wind NE, 4 knots, 11 rpms. Little sound today. The last 2 days I have had a lot of  crackling in my left ear. This morning I woke with the sound. It is like taking wax paper and crunching it next to the ear, but this is inside the ear.
    7:10 PM Wind E, 11 knots, 14.3 rpms, cloudy. Not too much noise due to wind in the trees. 11:10 PM Wind SE, 3 knots, cloudy, mist. dba 45.5, dbc 67.3. Jet sound. Much of today most turbines were not turning. Now the loud sound has returned.

September 22

– 5:15 AM Cloudy, foggy. Low hum. Afternoon-Working on the new porch was a tense afternoon. I could hear turbine 4 over the sound of a 4 row self propelled corn chopper and accompanying equipment. The chopper was between our house and the turbine.
   -7:30 PM Wind SE, 16.6 rpms. I can hear the turbines over the wind. There has been more sound the last few days or week and that has brought on more crackling in my left ear. While working on the porch 5  minutes after turbine 73 got louder my wife had a headache. 

September 23

– 6:45 AM Wind SE, light, 16.6 rpms. 8:10 AM My wife was trying to read at the dining room table and thought she heard a train, but it was the turbine sound instead. I woke up with the crackling in my ear. It has been pretty much constant the last 3 days. My wife also told me about a quivering she has in her chest, especially at night in bed. She had thought it  had something to do with her heitial hernia, but after reading some of Nina Pierponts writing I realized it is probably from the constant turbine sounds.
2:00 PM Wind S, 14 rpms. Turbine 4 has been shut down today. Maintenance trucks are at the base. Today I can hear turbine 3a because turbine 4 is not over powering it. I also hear turbines 73 and 74a.
10:55 PM Wind SSE 8 knots, 18 rpms, dba 48.0, dbc 61.4. Jet sound heard from turbines 4 and 73. Quite loud with
turbine 6 not quite as loud

September 24

– 5:15 AM Wind SW, 3 knots, 15 rpms, partly cloudy, dba 46.6, dbc 61.4. The sound is that of a jet flying over. 9:30 AM Wind SW, 3 knots, 11.6 rpms. There is the humming sound.
    10:25 PM Wind N, calm, 11 rpms with humming sound. I had crackling in my left ear much of  the day.

September 25 –

September 27

– Wind SW, calm, 11 rpms. Low hum. I woke up with left ear crackling.
8:55 AM Wind SW, light, turbine 4 14 rpms, turbine 3a 11 rpms. Turbine 4 is getting loud.
8:55 PM Wiind N 8 knots, 14 rpms. Turbine 4 and 6 are quite loud with #6 louder tonight. Turbine 6 is ¾ mi away

September 28

    S– 7:10 AM Wind NE, light breeze. Difference between dba and dbc is 20. That may Explain why my wife was awake for 2 hours over night.
    5:30 PM. 12.3 rpms. The turbines were off for a while. Ten rpms for a while. I was to our cabin today. It was so nice and peaceful☺ No annoying turbine sounds to pollute the air. I could hear birds and the rustling of the leaves. It
    was very peaceful and relaxing.

September 29

– 5:15 AM Wind calm. Turbines not turning. 9:00 PM Wind NW, 4 knots. Turbines not turning. Coudy.
    6:30 PM wind NW, calm, 11 rpms. Low hum but audible at the house.
    10:55 PM Wind W, calm. Turbines turning slow and fairly quiet. I can hear turbines 4 and 6.
    12:15AM Wind NW, 6 knots, 16 rpms, dba 45.6, dbc 60.8. I could hear turbine 4 while watching TV so I
    went outside to make sure it was the turbine. Turbine 4 and 6 are very loud whoosh. Turbine 6
    is ¾ of a mile away. We probably hear both tonight watching TV from our family room.

September 30 –

6;30 AM Wind NW, 7 knots, 13.6 rpms, cloudy, dba 43.9, dbc 59.3. I hear turbine 4
 loud and turbine 6 a little less.
5:10 PM. No facts other than wind from NW and it has been loud all day. I am tense and have crackling in my left ear. That is now every day even if I do not mention it.
10:05 PM Wind W, 17.3 rpms, dba 47.0, dbc 66.8. Turbines 4 and 6 loud, ripping the sky apart sound and jet flying over sound. Very bad. Our son saw the speed and said, “It will be a bad night”.  He was correct. He did not sleep at all this night.
