State regulators sided with the McLanes, generally, and operators will now have to use meteorological data to stop the blades before ice forms. The project's original state permit said the turbines would have to be paused only after ice is detected. (The PUC Order can be found by clicking the document icon to the right.)
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.
Beginning Nov. 1, 2016, and continuing on a daily basis, when the plaintiffs are outside on their properties, they are constantly confronted with irritating and unabated audible noise ...The plaintiffs claim inside their homes, they experience disturbed sleep, headaches, rapid heartbeat, anxiety, nervousness, joint pain, an inability to clear ears, fatigue, vertigo, depression, tinnitus, irritability and anger.
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.”
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.
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.
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.
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.
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.
Both Cindy Cobb and Sandra Wolfe from Calhan, Colo., live in the shadow of Golden-West, and blame the turbines for deteriorating health. They report dizziness, nausea, loss of sleep and headaches. They say their symptoms coincide with when the wind farm became operational in September 2015. Cobb adds lethargy and high blood pressure to the list of symptoms ...According to Wolfe, the relentless spinning causes stress and loss of sleep. She has resorted to sleeping off-site from her own property.
The final rule keeps the daytime sound level at 42 decibels, but the board changed the allowable nighttime level from 35 decibels allowed in the draft rule to 39 decibels. The board also kept a controversial setback limit of 10 times the height of the turbine, so that a 500-foot turbine would have to be at least 5,000 feet from the nearest residence.
About a year later, the board ruled in favor of Georgia Mountain Community Wind and determined that noise coming off the spinning turbine blades was not in excess of its state permit. But in that ruling the board said the McLanes and the Public Service Department could request additional testing if they could convince the board that the previous sound testing was not accurate.
VPIRG and REV have implied that the proposed rule will be the end of wind power in Vermont. In particular, VPIRG undertook a GIS study that showed that 0.2% of Vermont would be available for wind facilities due to the setbacks in the proposed rule. There are two problems with VPIRG’s analysis: its premise is wrong and the conclusion does not follow from its data.

The board has proposed limits of 35 decibels at night and 42 decibels during the day, as measured outside neighboring homes. Most turbines today are subject to a 45-decibel sound limit outside neighboring homes and a 30-decibel limit measured inside neighbors’ homes.
The board released its draft version of the new rules in March, and the board members held four meetings this week to hear from the public and from wind and sound experts as they get ready to finalize the sound standards.
Prospective neighbors of wind turbines heard all the promises: “Quiet as a library.” “Like a baby’s breath.” “The same decibel level as a refrigerator.” The more brazen wind developers claimed “you will not hear them.” Then the four hundred and fifty foot wind towers with their bus-size nacelles and three-bladed fans were built. Sixteen in Sheffield, four on Georgia Mountain, twenty-one in Lowell. And neighbors learned the truth. Yes, you can hear them. They sound like “a jet plane that never lands,” or “sneakers in a drier,” or there is a “thump thump thump” or a “whoosh whoosh whoosh” as the blade passes the tower, causing something called amplitude modulation.
