Wind Energy Facilities Law, Town of Richland, New York

Author:  Town Board, Richland, N.Y.

The Town Board of the Town of Richland finds and declares that:

5-1 The New York State Constitution’s “Bill of Rights for Local Governments” (Article IX, §2-10) obligates local legislators to protect the health, safety and well-being of their community.

5-2 While wind energy is a semi-renewable energy resource of electricity generation, and under some circumstances it may reduce the use of nonrenewable energy sources, the possible benefits must be balanced against potential negative impacts to local citizens, local economy, local ecosystems and regional military facilities.

5-3 Regulation of the siting and installation of wind turbines is necessary for protecting the health, safety and well-being of neighboring property owners, the general public, the local economy and local ecosystems.

5-4 Several independent legal and economic experts have concluded that there can be serious legal and economic detriments for landowners entering into the secretive, complicated and one-sided lease/easement contracts written by industrial wind energy developers.

5-5 Large-scale multiple-turbine industrial wind energy facilities present significant potential negative aesthetic impacts because of their enormous size, lighting, dissimilarity from the natural environment, and possible shadow flicker effects.

5-6 Installation of large-scale multiple-turbine industrial wind energy facilities can create and/or exacerbate drainage problems through erosion and lack of sediment control of facility and access road sites, and harm farmlands and agriculture through construction methods utilized and arable land conversion to industrial purposes.

5-7 Construction of industrial wind energy facilities can create traffic problems, dangerous road conditions for local and other travelers and damage local roads

5-8 There is significant evidence from independent appraisers that industrial wind energy facilities will likely reduce property values of nearby property owners. Said property value reductions will reduce the Town’s tax base, resulting in a tax rate increase on all Town property owners.

5-9 A large-scale industrial wind energy facility may be a significant source of noise and vibration, These can have negative health impacts on residents in neighboring properties, particularly in areas with low ambient noise levels. According to various medical experts (by way of limited example, the World Health Organization), the infrasound component of such noise can be the most problematic.

5-10 In certain circumstances, industrial wind energy facilities can cause electromagnetic interference with some types of communications.

5-11 Independent experts have concluded that bats killed by industrial wind energy turbines can result in an appreciable reduction in regional agricultural yields. Estimates have been done for every county in the United States, and these experts have projected that this could adversely affect our local community’s economy.

5-12 Independent experts have concluded that turbines kill large quantities of birds. Especially troublesome are the raptors that are destroyed. The Town of Richland is located on a major migration route for many species of birds, and is habitat for many species, both year-round and seasonal.

5-13 Independent experts have concluded that industrial turbines can have a variety of adverse health effects on other wildlife, livestock and domestic animals.

5-14 Independent experts have also concluded that industrial turbines can have a variety of adverse effects on hunting and fishing.

5-15 The Town of Richland has many scenic viewsheds, and some of these would be negatively affected by industrial wind energy facilities.

5-16 The Town of Richland is considering adopting a Local Waterfront Revitalization Plan which will include the establishment of a Scenic Overlay District in recognition of the importance of the scenic assets of the community.

5-17 Public and private dollars have been invested in infrastructure within the Town to enhance and promote tourism, an important regional industry. Several studies by independent experts have concluded that nearby industrial wind energy facilities can have a major negative economic impact on tourism-sensitive communities.

5-18 The Town and its citizens desire to maintain the pastoral, rural nature of this region. An industrial wind energy facility is in conflict with the culture and character of this community.

5-19 Due to the unusually broad array of potentially problematic findings (and lack of scientifically proven net benefits), the precautionary principle dictates that the Town be particularly conservative and cautionary in its regulation of industrial wind energy.

5-20 In formulation of this Local Law, many studies have been reviewed – and those written by independent experts were given the greatest consideration. (See WiseEnergy.org for good examples of such reports.) Many wind energy ordinances through the United States have been analyzed. Experiences of other communities with industrial wind energy have been studied. An ad hoc Committee was appointed to make recommendations regarding industrial wind energy regulation. Some of the Committee’s conclusions were incorporated into this Local Law.

Noise Impacts:

Applicant will provide a post-construction noise monitoring plan which shall, at a minimum, provide verification from a qualified party that at the WEF [Wind Energy Facility] boundaries and at proximate residences, WEF noise does not exceed 35 dBA for more than five (5) consecutive minutes during a representative range of operating and atmospheric conditions. Instrumentation to verify this shall meet ANSI or IEC Type 1 standards, and measurement procedures shall comply with relevant portions of ANSI 812.9, Part 3. Each report will include the SCADA/Power output data at the time of the testing.

WEF Dimensional Requirements:

To provide for at least minimal operational safety for persons and property located outside of a WEF, all WEFs shall comply with the minimums and maximums contained in the following table:

Type of Wind Energy Facility

Minimum Wind Turbine Setback* from any Property Line, Public or Private Right of Way, and/or Access Easement

Maximum Wind Turbine Height†

Small (≤100 kW)

1.5 feet for each foot of height from any property line and any vacant or occupied dwelling unit on the same property

75 feet

Large (>100 kW)

One (1( mile from facility property lines

500 feet

* Such minimum setbacks for a WEF shall be measured from its outermost extension (whether blade tip, nacelle/turbine housing, or tower/pole edge) that is nearest the WEF property line, public or private right-of- way, and access easement.

† Height is measured from the lowest adjacent grade to the highest point of the structure, including any attachments (such as a lightening protection device or a turbine rotor or tip of the turbine blade when it reaches its highest elevation). No portion of any wind turbine blade shall be closer than 25 feet to any portion of the ground that surrounds any WEF. No LWEF wind turbine shall be permitted to be within five (5) miles of any operating or proposed radar facility (NEXRAD, military, commercial etc.).

Re: Falmouth Wind II Turbine Relocation Study

Author:  Rand, Robert

This letter (PDF attached) is respectfully submitted to the Town of Falmouth to provide a qualified professional opinion about the proposed relocation of Wind II. This is submitted independently as a courtesy to the Town free of compensation from any party.

The original permittings for Wind I and Wind II (and NOTUS) resulted in neighbor complaints soon after start-up and were confirmed to exceed Falmouth’s 40-dBA noise limit (turbines sited too close). Weston & Sampson’s relocation recommendation for Wind II appears to be inconsistent with the Town 40 dBA noise limit and the 2017 Barnstable Superior Court Decision.

1. The distance to meet 40 dBA for Wind II, a Vestas V82 with sound power level of 110 dBA, is approximately 891 meters or 2923 feet. This is greater than the setback distances provided by the proposed new location. The proposed new location is still too close.

2. At 2147 and 2244 feet listed in the subject report, the expected sound level is 43 dBA.

3. Use of the proposed new location appears certain to result in the relocated wind turbine’s maximum noise levels exceeding the Falmouth noise limit of 40 dBA.

4. Use of the proposed new location appears certain to result in the relocated wind turbine’s maximum noise levels exceeding established background sound levels of 27-28 dBA by over 10 dB, breaching State 10-dB noise limits.

Supporting detail is provided in the attached PDF. Please contact me if you have any questions.

Respectfully Submitted,

Wind Turbine Public Safety Risk, Direct and Indirect Health Impacts

Author:  Palmer, William

Abstract —
Wind turbines are often perceived as benign. This can be attributed to the population majority dwelling in urban locations distant from most wind turbines. Society may understate the risk to individuals living near turbines due to an overstatement of the perceived benefits of turbines, and an understatement of the risk of injury from falling turbine parts, or shed ice. Flaws in risk calculation may be attributed to a less than fully developed safety culture. Indications of this are the lack of a comprehensive industry failure database, and safety limits enabling the industry growth, but not protective of the public. A comprehensive study of wind turbine failures and risks in the Canadian province of Ontario gives data to enable validation of existing failure models. Failure probabilities are calculated, to show risk on personal property, or in public spaces. Repeated failures, and inadequate safety separation show public safety is not currently assured. A method of calculating setbacks from wind turbines to mitigate public risk is shown. Wind turbines with inadequate setbacks can adversely impact public health both directly from physical risk and indirectly by irritation from loss of safe use of property. Physical public safety setbacks are separate from larger setbacks required to prevent irritation from noise and other stressors, particularly when applied to areas of learning, rest and recuperation. The insights provided by this paper can assist the industry to enhance its image and improve its operation, as well as helping regulators set safety guidelines assuring protection of the public.

Wind turbine low frequency and infrasound propagation and sound pressure level calculations at dwellings

Author:  Keith, Stephen; et al.

Abstract
This study was developed to estimate wind turbine low frequency and infrasound levels at 1238 dwellings in Health Canada’s Community Noise and Health Study. In field measurements, spectral peaks were identifiable for distances up to 10 km away from wind turbines at frequencies from 0.5 to 70 Hz. These measurements, combined with onsite meteorology, were in agreement with calculations using Parabolic Equation (PE) and Fast Field Program (FFP). Since onsite meteorology was not available for the Health Canada study, PE and FFP calculations used Harmonoise weather classes and field measurements of wind turbine infrasound to estimate yearly averaged sound pressure levels. For comparison, infrasound propagation was also estimated using ISO 9613-2 (1996) calculations for 63 Hz. In the Health Canada study, to a distance of 4.5 km, long term average FFP calculations were highly correlated with the ISO based calculations. This suggests that ISO 9613-2 (1996) could be an effective screening method. Both measurements and FFP calculations showed that beyond 1 km, ISO based calculations could underestimate sound pressure levels. FFP calculations would be recommended for large distances, when there are large numbers of wind turbines, or when investigating specific meteorological classes.
