Draft legislation backed by Gov. Deval Patrick has again placed the Vineyard front and center in the statewide push to build large-scale wind farms on land and at sea, sparking some concern here that the rush to adopt clean energy technologies could come at the expense of fishing grounds, scenic views and the Island’s unique powers to regulate development through the Martha’s Vineyard Commission.

Governor Patrick is aggressively promoting the development of green energy technologies in separate initiatives: the draft Oceans Management Plan, which has identified areas south of Noman’s Land and Cuttyhunk for large-scale commercial wind farms, and the Wind Energy Siting Reform Act, which would streamline approval of land-based wind turbines around the state.

The Oceans Act was signed into law last year; rules and regulations are still being formed in the draft plan attached to the act. Language in the law will allow the state Energy Facilities Siting Board to supercede local zoning and the commission, the regional planning agency created by an act of the state legislature some 35 years ago that has broad powers to regulate development. This marks the first time that the commission’s authority has been trumped by another state agency.

Meanwhile, the Wind Energy Siting Reform Act, a separate piece of legislation, could again allow the state Energy Facilities Siting Board to supercede the commission’s decision-making authority on a wider range of wind turbines, at land and in the sea, unless the commission adopts its own siting standards and has them approved by the state Department of Energy Resources.

The commission currently has not adopted standards. But executive director Mark London said he is confident the commission will do so, although he did not articulate a timetable. He said the commission currently has no plan to challenge the legislation.

“It doesn’t make a lot of sense to bring legal action against the state legislature; they are the ones that created the commission. It’s not some outside entity,” Mr. London said.

The state’s two wind energy initiatives will be the topic of an information session sponsored by the commission on Wednesday at 7:30 p.m. at the Tisbury Senior Center. The state will hold a final public hearing on the draft Ocean Management Plan on the Island on Sept. 23 at the Katharine Cornell Theatre in Vineyard Haven.

Although the Wind Energy Siting Reform Act could lead to a run on new land-based wind turbines on the Vineyard — which has some of the best wind conditions in the state — most of the discussion on the two wind initiatives on the Vineyard so far has focused on the draft Ocean Management Plan.

Some town officials, as well as members of the commission staff, have expressed relief that a larger portion of the Vineyard coastline was not identified for possible wind farm development. At one point there was concern that almost two thirds of the Vineyard — to the east, south and west — could be opened up for turbines.

But there has also been criticism of the plan, beginning last week with the Chilmark selectmen, who blasted the state, calling the plan politically motivated and suggesting that the Vineyard was singled out because it has no political clout on Beacon Hill.

By way of comparison, the entire Cape Cod Ocean Sanctuary, the eastern coast of Cape Cod, was exempted from wind turbines under the plan, and the entire shoreline of Nantucket was exempted from commercial wind turbines, largely because the area is a breeding ground and migratory flyway for several endangered birds, including the long-tailed duck.

Members of the Wampanoag Tribe of Gay Head (Aquinnah) have expressed concern that wind farms allowed under the plan would impair scenic views from the Gay Head Cliffs and threaten sites important to cultural traditions of the tribe.

And fisherman are worried about damage to valuable fishing grounds, including around Noman’s Land, long a prime spot for lobster fishing.

Michelle Jones, a fisherman and secretary for the Dukes County Fishermen’s Association who has attended public hearings on the draft Ocean Management Plan, said the state plan has placed Island anglers in a tough spot. While most support green energy initiatives, they also are concerned that a rush to build large wind farms could be something the Vineyard lives to regret.

“But if we come out and say we’re opposed to this, people look at us and say, ‘Well, you just don’t want it in your backyard.’ And that’s not true. We want to move toward greener energy, it’s what is best for the world. But at the same time we want to protect these vital fishing grounds,” she said, adding:

“These fisherman are trying to make a living in a trade that most have worked since their early teens. Every year it gets harder; more red tape, more paperwork, higher costs . . . these guys keep fishing against all odds. And here comes this plan to put up these wind turbines in the middle of their fishing grounds. All we are saying is talk about this more, let’s do this right.”

Ms. Jones said she is hopeful there is still time for the state to change the plan. She is working on a chart that identifies where fishermen do most of their fishing, which is not easy considering most anglers are reluctant to reveal their secret spots. She plans to submit the data before the final plan is completed later this year.

She too questioned why the Nantucket coastline is not included as a designated place for commercial wind farms. “We have plenty of long-tailed ducks too, except over here we call them old squaw,” she said.

Matt Pelikan, a well-known bird expert and the Islands program director for The Nature Conservancy, also has concerns about the draft Ocean Management Plan. He said the areas identified for commercial wind farms are important breeding grounds and migratory habitats for several rare bird species, including peregrine falcons and certain types of wintering sea ducks.

He said much of the birding information used to draft the maps came from ornithologists from the Mass Audubon Society, who in his opinion are highly qualified. But he noted the information they provided may have unintentionally slighted breeds found on the Vineyard.

“The Mass Audubon ornithologists are top-notch. But I think whenever you enlist experts examining a large amount of data you run the risk of ignoring a specific regions like the Vineyard. And these results may be limited simply because conclusions were drawn from the experiences and specialization of the experts,” Mr. Pelikan said.

Mr. Pelikan is working with other birders to compile comprehensive data on bird populations on the Island. He also encouraged public attendance at the information forum next week and the public hearing later this month.

“People should be active in this process; they should go to the public hearings and submit written commentary. There is still meaningful input to be made,” he said.

Ms. Jones agreed.

“This is not the final version of the plan . . . there is still time [to make changes]. I don’t think people realize how important this is; we are talking about the future of our coastline and our Island. People need to get involved while they still can,” she said.
