By the time federal regulators stopped accepting public comments about the proposed Nantucket Sound wind farm on Monday, two of the letters had already raised some eyebrows among the project's critics. That's because the two letters were signed by the same person, state Division of Marine Fisheries director Paul Diodati, but they struck noticeably different tones. ...Diodati's first letter [dated Feb. 20] spells out the loss of access that fishermen could face as well as concerns about rescue crews reaching a troubled boat in the area. But the second letter, dated March 7, tones down the rhetoric considerably, reducing the section that lists the potential impacts to fisheries to just a few sentences. The section also mentions a couple of possible benefits, such as certain species becoming attracted to the newly built tower foundations.

But the Alliance to Protect Nantucket Sound cites more than a few environmental impacts in the DEIS that it believes the Minerals Management Service and the rest of the agencies reviewing the massive project need to pay closer attention to. Impacts on birds, scenic views, navigation, fish species, fishing and boating all received a moderate rating from the MMS. The Alliance also calls into question what it terms the excessive cost of Cape Wind's wind energy and air travel hazards over Nantucket Sound in proximity to the wind farm. Alliance President and CEO Glenn Wattley said the Alliance is working now to examine each impact that was given a moderate characterization by the MMS and figure out ways to address them. "We've been retaining experts," he said. "We have 40 experts on these topics, they are going over the topics [and] we're spending quite a bit of money putting together a professional response for the public comment period," he said.

Following a public hearing yesterday, the Cape Cod Commission voted to recommend a new adjudicatory process for Development of Regional Impact reviews of energy-related facilities under the jurisdiction of the state Energy Facilities Siting Board. Commission chair Bob Jones of Sandwich advised with a smile that he could save some "heartburn" for audience members by announcing that language making the changes applicable to the Cape Wind project would not be included. Actually, he probably just shifted the upset from backers of the project to its opponents. The latter had hoped Commission action would have established a process that would satisfy the EFSB's standards.

The state's largest commercial fishing organization is publicly challenging assertions by the developer of the Cape Wind project that their offshore wind energy project will actually improve fishing in Nantucket Sound. The Massachusetts Fishermen's Partnership (MFP), which is comprised of 18 commercial fishing organizations, decided to take its message to the airwaves in a TV commercial now appearing on several channels, said Executive Director David Bergeron, "because the public needs to know that sustainable commercial fishing would be impacted and displaced" by the Cape Wind development project on Horseshoe Shoal.

NEW BEDFORD - The Boston developer who wants to build a 300-megawatt wind farm in Buzzards Bay called the results of preliminary bird studies "encouraging" but said it is too early to determine whether threats to endangered terns that nest and feed in the bay could kill the $750 million project. "I am fifty-percent comfortable," said Jay Cashman of Patriot Renewables, LLC., a renewable energy subsidiary of his construction company, Jay Cashman Inc.

Both supporters and opponents of the proposed Nantucket Sound wind farm are hailing the findings of recent research on the environmental impact of Danish offshore wind turbines. Supporters of Cape Wind Associates' plan to build 130 wind turbines in Nantucket Sound say the research released last week at an international conference supports their contention that wind farms pose little threat to wildlife. But Cape Wind foes say the Danish research highlights the need to carefully study the environmental impact of offshore wind turbines on a case-by-case basis.

The phrase ''not permittable'' is typically the last thing a developer wants to hear. But that's exactly what the state environmental office has called Boston construction magnate Jay Cashman's proposal to build a 120-turbine offshore wind farm in three clustered Buzzards Bay sites. If Cashman wants to pursue his renewable energy plan, he ''proceeds at the risk of denial'' because the sites fall within the Cape and Islands Ocean Sanctuary, according to a certificate written by former Secretary of Environmental Affairs Stephen Pritchard that lays out the state's scope of review over the project.

A Romney administration report has concluded that a proposal by a prominent Boston developer to build up to 120 wind turbines off Buzzards Bay would violate state law and could threaten an endangered species of bird.

Boston construction giant Jay Cashman wants to build a massive wind farm in pristine Buzzards Bay, but says there is one potential obstacle. "The one thing I am concerned about is birds," Mr. Cashman told a group in Fairhaven when he unveiled his $750 million renewable energy project earlier this month.

BUZZARDS BAY — Researchers at Massachusetts Maritime Academy are studying how the school's new 241-foot wind turbine is affecting the flight patterns of birds that fly around the windy campus.

Before Cape Wind can build turbines on the sound, it first must prove to skeptics - and the state - that, among other things, the 417-foot-tall towers won't harm birds.

The Sierra Club will announce its conditional support today for the Nantucket Sound wind farm, saying it would provide clean energy without posing a significant threat to wildlife habitat or birds.

The Massachusetts Audubon Society gave its preliminary blessing yesterday to a large-scale wind power project off Cape Cod, saying its studies show that turbine blades are not likely to cause significant harm to birds, as the group had once feared.......But the group said its final decision will hinge on additional research of several bird species.

When it comes to Cape Wind Associates’ plan to create a 130-turbine wind farm on Nantucket Sound, environmentalists not only disagree, some can’t even agree as to whether or not there’s a disagreement.
