Health Impact Concerns from Data Supplied With the Badger Hollow Wind Power Plant Proposal (Docket, 9827-CE-100 )
Affected Landowner Comments Due Dec. 20, 2024. Instructions.
On November 21, 2024, the Public Service Commission and Department of Natural Resources of Wisconsin sent this IMPACT COMMENT OPPORTUNITY NOTICE to residents, local governments, counties, schools and other organizations that would be affected by the construction and operation of the 24.5 square mile, Badger Hollow wind power plant in the Towns of Clifton, Eden, Linden, Mifflin, Wingville, Lima and Belmont in Iowa, Grant and Lafayette Counties, Wisconsin.
“[T]he agencies are requesting comments from the public to help the state agencies determine the potential impacts associated with the project and the scope of the Environmental Assessment (EA). . . Comments for the EA scoping are most effective when they discuss:
Any potential human and environmental impacts of the proposed wind generation project; or
Any specific actions or changes to the proposed project that might minimize or mitigate the potential impacts of the project.“
Impacted residents may find benefit in reviewing the following impact estimations from Invenergy’s commissioned, health-related analyses, Appendix Y-Noise; Appendix Z-Shadow Flicker; Appendix Y-EMF, and maps in Figure 4.1.2 and Figure 4.4.1 .
- ~370 Residents Predicted to Experience Audible Noise Under Quiet Conditions
- Nauseogenic Illnesses from wind turbine air pulses documented up to distances of 4 miles (Vertigo, dizziness, headaches, nausea, tiredness, irritation, uneasiness and difficulties with concentration.
- ~100 Residents predicted to be subject to at least 10 Shadow Flicker Hours per year with some residences undergoing 48 hours per year. Approximately 452 residencies would be subject to at least one minute of Shadow Flicker per year with a mean of 3 hours and 20 minutes per year.
- ~22 miles of vegetation management on easements through Agricultural Fields, Pastures
- 25 Stream Crossings
- Electromagnetic Field Concerns From ~22 miles of buried 34,500 volt (34.5 kV) connection lines.
Step 1. Find Your Assigned Residency Number to Assess Your Exposure to the above, Negative Impacts.
A. Click on the below map to open it in another window and zoom into it or, click on one of these links if you live in a village Invenergy has evaluated: Cobb, Livingston and Rewey. WRITE DOWN YOUR RESIDENT NUMBER (eg.”R-0018″). Iowa Grant High School residency numbers are R-1708 & R-1709

Step 2. Determine the Predicted, Audible Noise Impacts For Your Location
Click-on the two, below lists and search for your Resident/Farm number. If your house is not included, your exposure to audible wind turbine is probably at the lower range of concern.
56 Most Noise-Affected Residents
313 Additional Noise-Affected Residents
Step 3. Determine the Nauseogenic Health Risks for Your Location
Refer to the 2-MIle and 4-Mile impact maps, below. Darker shaded areas reflect higher concentrations of air pulses– the extremely rapid changes in barometric air pressure that produce a variety of short and long-term health risks.
All persons are not subject to immediate negative impacts including, vertigo, dizziness, headaches, nausea, tiredness, irritation, uneasiness and difficulties to concentrate, but person who experience motion sicknesses frequently are. The slower blade rotations from the extremely large, 6.2 MW turbines are expected to increase health risks. Negative health impacts from the smaller, Red Barn turbines near Montfort/Livingston, have already been documented at a distance of 4 miles.
Affected schools, places of worship and assisted living/nursing home sites have been added to the 4 Mile radius impact map from Invenergy’s Figure 4.1.7.2. Iowa Grant High School residency numbers are R-1708 & R-1709




Step 4. Determine Shadow Flicker Health Risks for Your Location
The experience of Shadow Flicker, the effect of pulsating light and shadow is produced by the sun shining through rotating wind turbine blades. The developer proposing the Badger Hollow wind power plant has predicted the number of hours per year that residents in the impact area can expect to experience Shadow Flicker. A list of 234 farm/residential locations predicted to be subject to at least 5 hours of Shadow Flicker per year has been provided, below. One can also use one’s residence number and the below map to help assess one’s risk exposure. If you are not aware of the experience of Shadow Flicker, this video produced at a Wisconsin location provides useful documentation.

Step 5. Determine Low Frequency, Electromagnetic Field Health Risks for Your Location
There is continuing controversy about how to test and predict EMF health impacts. Developers favor short-term sampling, lab-based modeling while medical findings incorporate long-term field/patient observations. As for potential EMF impacts with the Badger Hollow Wind proposal (BHW), it is important to note the lack of short and long-term studies of close to the surface, buried, 34.5 kV “connection” transmission lines. Invenergy’s study for BHW proposes to bury 1 to 5 circuits of these high voltage/high current lines only 4.5 feet below pastures, croplands and other areas– creating about 22 miles of 20-100 foot wide impact swaths. Further, the lab analysis suggests each of these connection line circuits would produce continuous EMF levels to 10 milliGauss– the level of radiation emitted by the average microwave oven at 2 feet.
In direct testimony filed before the Minnesota Public Utility Commission, Dr. David Carpenter accounts for, “strong scientific evidence that exposure to magnetic fields from power lines greater than 4 milliGauss (“mG”) is associated with an elevated risk of childhood leukemia” based on his epidemiological research including patient experiences. While communities await long-term field studies on buried 34.5 kV lines, Dr. Carpenter warns, “there is sufficient scientific evidence to cause concern about leukemia risks at [sustained] exposures above 2 mG.”
This PSC WI Publication has considerable info on EMH health studies and origins of epidemiological research.
The below graphic was made from data supplied in Invenergy’s commissioned EMF analysis for BHW.

All studies seem to agree that steady, close-range exposure to EMF is needed to produce higher end risks. Below is a list of BHW residency numbers with closer proximities to proposed, buried, 34.5 kV collection lines.
