Individual members of the grassroots group Ridge Protectors Inc., filed an appeal in Vermont's Environmental Court arguing that more ground would be disturbed by the Sheffield wind facility than was approved in the storm water discharge permit issued by the State's Agency of Natural Resources (ANR). The wind developer, First Wind has been approved by the Vermont Public Service Board to erect sixteen 2.5 megawatt wind turbines along a ridgeline in Sheffield, Vermont. The final brief filed by the Ridge Protector appellants can be accessed by clicking on the link at the bottom of this page. An excerpt of the brief is posted below.

This document includes on-the-ground photos of the Allegheny Ridge wind farm in Pennsylvania which show the extent of land impacted by road development. The degree of clearing shown is typical for ridgeline wind energy development; however, as stated below, the clearing does not reflect pre-approval assertions made by the developer.

Here is a reprint of an email about ice throw at Green Mountain Power's Searsburg wind energy facility in Searsburg Vermont. The email was written by John Zimmerman to an American Wind Energy Association listserv in 2000. Mr. Zimmerman managed the development of the Searsburg facility

Excerpts below are from the May 16, 2007 Proposed Order of WV PSC denying Liberty Gap's application for CPCN (siting permit) for 50 wind turbine project atop Jack Mtn in Pendleton County:

An indictment of the Scottish Executive and regulatory incompetence and indifference......‘One is left with a clear impression of inertia, bungling, duplicity, poor communication, procrastination, obfuscation and, quite frankly, shoddy and incorrect decision-taking both in temporal and technical terms'.

Professor Terry Matilsky, associate professor of physics and astronomy at Rutgers University, addresses the kinetics of ice throw.

Starting with our first interagency meeting on April 8, 2005, we have generally discussed three broad categories of activities that pose a potential concern for fish and wildlife resources. These include the potential for bird and bat collisions with turbines, habitat fragmentation effects on wildlife and impacts to waters/wetlands. At the April 8, 2005 interagency meeting, we recommended that CEI collect three (3) years of radar data on spring and fall bird/bat migrations to document the spatial and temporal use of the airspace by these flying vertebrates. Three years of radar data should be sufficient to gather information on the spatial and temporal distribution of birds in the airspace, including the year-to-year variability in migration patterns at this site, and represent our normal request for these data at wind projects. We have consistently requested that this data be collected at our meetings and field visits and continue to make this request for radar information.

Dr, Kenneth Jaffe's response to the health and safety content of a June 2006 presentation by the NY State Department of State (DOS) in Delware County, NY.

The DOS presentation, which included a discussion of the impact of industrial turbine projects on communities and individuals, is intended to guide local officials in the process of writing regulations. Dr. Jaffe's response addresses what he believes are substantive misstatements, mischaracterizations, biased emphasis and faulty data contained in the DOS presentation.

During a recent roundtable discussion concerning wind power projects at the Delaware County Historical Society a participant affiliated with two local wind development companies stated that there were three issues where the health and safety impacts were predictable and avoidable---- ice throws, noise, and flicker. Since the statement was made in the presence of planners who are advising towns in the process of writing regulations to protect the health and safety of residents, I felt that a fuller discussion of the known science of these issues was important, and have prepared this report to that end.

Editor's Note: Dr. Jaffe's presentation to the Town of Meredith Planning Board on the proposed industrial wind plant vis-a-vis Meredith's 'vision' is available via the link below.

Editor's note: This short document prepared by personnel at the Wind Application Engineering Group of GE Energy provides some insight into the risks of ice throw. The content of this document confirms that ice fragments can be thrown large distances from the turbines.
