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.

Date: October 7, 2013

Height Limit: The Wind Advisory Committee recommends that any premises-use turbine does not exceed 120 feet from grade to the tip of the blade.

Capacity: The Wind Advisory Committee recommends that the output of nameplate capacity be limited to 10 KW for residential and 30 KW for agricultural/business use.

Excess: In order to comply with the intent that the output be primarily for premises use, the Wind Advisory Committee recommends that the rated name capacity be restricted to the smallest unit available to cover the intended premises use.

Noise: The Wind Advisory Committee recommends that the noise limit of any wind turbine shall not exceed 5 dB above ambient at any lot line and the nearest inhabited residence. The ambient level shall be established by the applicant prior to the submission of an application by a protocol to be determined.

Flicker: The Wind Advisory Committee recommends that the By-law shall not allow any flicker affecting occupied buildings.

Aesthetics: The Wind Advisory Committee recommends to the Planning Board that they take visual impacts and property values considerations into account in the permitting process.

Setback: The Wind Advisory Committee recommends that the setback be double the height of the blade tip from any roadway, structure, or property line.

Certification: The Wind Advisory Committee recommends that any premises-use wind turbine must be an approved turbine on the list certified by the Small Wind Certification Council or other certification agency as approved by the State of Massachusetts.

One turbine per premise: The Wind Advisory Committee recommends that only one turbine be allowed per premises.

Critical analysis of: Wind turbine health impact study: report of independent expert panel

Author:  Schomer, Paul; and Pamidighantam, Pranav

Abstract. The “Wind Turbine Health Impact Study: Report of Independent Expert Panel” study says: “The Massachusetts Department of Environmental Protection (MassDEP) in collaboration with the Massachusetts Department of Public Health (MDPH) convened a panel of independent experts to identify any documented or potential health impacts of risks that may be associated with exposure to wind turbines, and, specifically, to facilitate discussion of wind turbines and public health based on scientific findings.” It continues, saying: “The scope of the Panel’s effort was focused on health impacts of wind turbines per se.” The Massachusetts study treats health affects broadly in accordance with WHO and includes direct health effects, annoyance, and sleep disruption. In many ways the Massachusetts study is a critique of the literature relating to wind farm acoustic emissions and health effects. This paper is a critique of the critics. In particular, this critique examines some of the physical acoustic findings and some of the social survey findings. The Massachusetts study reveals itself to have problems similar to those that it criticizes in other reports.

Hoosac Wind Turbine Noise Studies

Author:  Ambrose, Stephen; and Rand, Robert

Back to the Future II … This is a true story, depicted by Marty and Doc. Their mission: Identify the ignored warnings in the Hoosac wind turbine studies. That opened rifts into an alternate universe, where noisy wind turbines were permitted to invade homes. The wayback clock is set to: OCT 06 2003 …

First study: October 6, 2003
Special permit application for Enxco Incorporated, Hoosac Wind Project, Florida/Monroe, Mass.
Compiled by: Hill Engineers, Architects, Planners, Inc., Dalton, Mass.

Florida and Monroe are rural, so how quiet?
There are no busy roads or commercial activity. This chart shows a “Quite Rural Nighttime” at 25 dBA and even less.

common-outdoor-sound-levels

Does Massachusetts have noise limits for large wind turbines?
Yes, look at the MassDEP noise policy:

Noise is a public health concern that falls withing the scope of Massachusetts Department of environmental Protectin authority as a form of regulated air pollution. …

Noise is a type of air pollution that results from sounds that cause a nuisance, are or could injure public health, or unreasonably interfere with the comfortable enjoyment of life, propert, or the conduct of business. …

A noise source will be considered to be violating the Department’s noise regulation if the souce … increases the broadband sound level by more than 10 dB(A) above ambient. … These criteria are measured both at the property line and at the nearest inhabited residence. “Ambient” is defined as the background A-weighted sound level that is exceeded 90% of the time.

Will neighbors complain?
ISO has a simple table:

noise-complaint-response-levels

We need to read the report …

Results of the study indicate that the highest average noise level at an occupied residence will be 42.6 dBA. The lowest level of the eight homes in the study was 36.6 dBA.

They wrote this without knowing how quiet the area is?
Let’s look at the noise data they used in appendix E.

Maximum noise level allowable for each receptor location: 55 dBA

The existing ambient noise level is 55 [or 45] dBA?
This is a BIG mistake! “Quiet Rural Nighttime” is less than 30 dBA. 55 dBA is TOO LOUD.

Second Study:
Decision on application for special permit
Town of Florida Board of Selectmen

Special Permit Conditions:
The turbines shall be operated so that sounds generated by the turbines shall not exceed 65 dBA at any property line that is not a part of the Hoosac Wind Project by more than 20 dBA at any time, or by more than 10 dBA for more than ten minutes in any hour, or at all for more than thirty minutes in any hour.

This Florida Board decision makes no sense.
A peer review by a community noise expert would have predicted “Very Strong” reaction.
Widespread Complaints!!
MassDEP recognizes this: Turbine max noise no more than 10 dB above ambient (L90).
Plus 20 dB is the HIGHEST REACTION!!!

Third Study:
Hoosac Wind sound level monitoring
Resource Systems Group
19 1.5-MW GE 1.5sle turbines: 10 on Bakke Mountain, 9 on Crum Hill

Fig. 2: Common sounds in A-weighted decibels
Quiet rural area, no wind, insects or traffic: 30 dBA
Quiet winter night, wilderness area, no insects, traffic or wind: 20 dBA

How can a “Quiet rural area” be ignored?
Increase background ambient with wind?
Measure wind noise?
Look at the Hoosac measurement pictures: Sound level meters are too close to trees.

Can wind turbine noise measurements mislead?
Yes, when the turbine is not operating normally. GE 1.5-MW turbines produce an “acoustic fingerprint”, a tone at 160 Hz. Fig. 28 shows that fingerprint at 125 Hz, indicating an RPM slower than normal. Fig. 30 shows the fingerprint at 100 Hz.

How else?
Chris Kapsambelis plotted the turbine power output vs. wind speed given in the Hoosac sound study and the published GE 1.5sle data:

In comparing the recorded power output to the published power curve data, it is clear that the wind turbines were not operating normally. The power output was as much as 33% less than normal, which would mean that the sound power level was also substantially reduced.

hoosac-power-curve

These graphs raise questions about their noise measurements.

The maximum monitored sound levels from the wind turbines, with background subtracted, ranged from 29 dBA at Tilda Hill North to 43 dBA at Moores Road North. [no nearby residences identified]

They confirmed Hoosac turbines over 10 dB!
43 dBA is too loud by their own data tables.

hoosac-sound-levels

Hoosac’s artificially low noise levels are above the MassDEP noise limit.
Again, measurements show Hoosac is too loud! Even at lowered power output!
