Councilman Wayne Rogers called on his fellow Town Board members to explore modifications to the town law adopted prior to the construction of the Jericho Rise project to address some of the problems that have arisen since the wind farm began operation at the end of last year.
In November 2014, Health Canada released the results of its $2.1 million “Wind Turbine Noise and Health Study.” Despite public anouncements from Health Canada that the raw data originating from the Study would be made available, the data continues to be inaccessible making it impossible to validate the conclusions drawn by Health Canada researchers. For example, HC found high levels of annoyance but concluded no association to turbine noise.
David Janes of rural Toronto, South Dakota, said he and his late wife had built a retirement home on their South Dakota farm site 17 years ago. ...“But when the turbines are running, I can’t hear the birds. All I hear is swoosh, swoosh swoosh, like a jet plane engine.”
More research will be required to determine safe set back distances from wind turbines, a leading scientist said in Tullamore last week. Dr Mariana Alves-Pereira was speaking to the Tribune after addressing a seminar on the effects of the turbines on animal and human health.
The question of whether wind turbines are physically capable of producing the adverse reactions claimed is unresolved. However, it is now scientifically demonstrated by Swedish researchers that amplitude-modulated low-frequency wind turbine noise can directly cause sleep disturbance, even in young fit people taking part in its research study.
Windfarms louder than birdsong will be forced to shut down under new regulations due to take effect early next year. ...But Mr Naughten said the regulations included a "zero-tolerance" approach to shadow flicker and nuisance sound.
It's all likely to prove academic, since LCAR is almost certain to vote down the rules sometime after leaf-peeping season. At that point, the PSB would have to resume work on a new set of rules. Given the fact that the board and the Scott administration take a dim view of ridgeline wind and most legislators are in favor of renewable energy including wind, it's going to be very tricky to find a set of rules acceptable to all parties.
A legislative panel has deferred action on a proposal that could have significant impacts on the future of ridgeline wind energy in Vermont.
The purpose of this paper is to explain and evaluate the metric by which the community response to wind turbine noise is gauged and the limits appropriate to that response function. Chapter II deals with selection of the metric, and Chapter III presents the data and methods used to establish criteria and a criterion, based on the metric selected. The abstract of the paper is provided below. The full paper can be accessed by clicking the links on this page.
Permit enforcement is a concern raised at nearly every public hearing for renewable energy projects. People want the government to protect them if and when a company violates the terms of its operating permit. It's hard to trust that the government will do that when so much of the monitoring process is in the hands of the company being monitored or its agents.
The DPS requested that the board “reject the proposed sound monitoring protocol and require Deerfield Wind to submit a revised protocol” that includes the department’s suggested changes. The department’s stance was echoed by the Wind Action Group and Thomas Shea, who owns property in Searsburg and is an intervenor in the project permit process.
This important study has identified flaws in the current compliance testing for wind turbine noise and further outlined the methods necessary for identifying and measuring the low-frequency, pulsation that isoften times reported by those impacted by the turbines. Specifically, the "presence of amplitude modulation in the low frequency region, that modulates at an infrasound rate, at or near the threshold of hearing" has been identified and may support the symptoms reported by Dr. Nina Pierpont in her work, Wind Turbine Syndrome. The introduction and conclusion of the paper is provided below. The full paper can be accessed by clicking the links on this page.
It was the humming sound of a wind turbine at 750 metres which certainly stood out to the hundreds of people who turned up at the information meetings both at Gneeveguilla and Ballydesmond.
Under the proposed rules, noise from large turbines would be limited to 42 dBA during the day and 39 dBA at night; smaller turbines would be limited to 42 dBA. ...Developers also would have to build large wind turbines away from local residents by a distance of 10 times the height of the turbine.
In several records, staff noted that wind turbine noise exceeded regulations: ““Staff have attended at the complainants homes on multiple occasions … noise measurements were obtained…subjective observations were made by Provincial Officers…the conclusion of the POs were that the noise emissions from the wind turbines were causing an adverse effect contrary to S. 14 (1) of the EPA at the complainants locations…”
On Thursday, an obscure legislative committee will have the final say over new wind-power rules that have sent shock waves through Vermont's renewable-energy community.
A small group of residents in eastern El Paso County has spent at least $65,000 on research that they say should be enough to shut down an area wind farm.
Of the nearly 3,200 reports, 1,730 didn’t get site visit from ministry staff. Action on another 1,424 incidents was listed as deferred or planned. Only 24 public complaints on wind turbine operations between 2006 and 2014 were given priority status, according to ministry records obtained by Wind Concerns Ontario. Wilson said noise issues were the most common complaint.
This powerful document identifies and explains how the Ontario Government through its Ministry of the Environment and Climate Change dismissed, ignored, and otherwise failed to address thousands of wind turbine noise complaints in the period from 2006 to 2014. Nearly 3,200 reports of noise complaints were made during that time and in more than half the cases, the government took no action. The wind power industry was virtually self-regulating as the Ministry relied on predicted noise modeling to determine compliance rather than actual measurements. An excerpt of the report released by Wind Concerns Ontario is provided below. The full report can be accessed by clicking the links on this page.
The Town Board had planned to allow a third-party firm to test the noise levels generated by the towers of the Jericho Rise Wind Farm in the area where a number of complaints have been raised. Town Supervisor Don Bilow said that the Jericho Rise’s parent company, EDP Renewables, has “stonewalled” attempts for an outside test.
