USA: BOEM Identifies Sites for Wind Farms Offshore Massachusetts

As part of Secretary of the Interior’s Smart from the Start Atlantic Offshore Wind Initiative, the Bureau of Ocean Energy Management (BOEM) announced that it is moving forward with the next step to consider commercial wind energy development on the Outer Continental Shelf (OCS) offshore Massachusetts.

Together with the commonwealth of Massachusetts, BOEM has completed definition of a Wind Energy Area (WEA) with high wind potential for possible commercial leasing.

 “The Wind Energy Area that we are announcing today is the result of extensive work with our partners in the Commonwealth and with a broad community of stakeholders as we move forward with responsible leasing and development of offshore wind resources,” said BOEM Director Tommy P. Beaudreau. “The area off of Massachusetts has tremendous energy generation potential, and we will continue to evaluate and mitigate the potential impacts of offshore wind energy development on wildlife habitat, fisheries and sea bird migration.”

The WEA defined today begins approximately 12 nautical miles south of Martha’s Vineyard and 13 nautical miles southwest of Nantucket. From its northern boundary, the area extends 33 nautical miles southward to the 60 meter depth contour and has an east/west extent of approximately 47 nautical miles. The WEA is approximately 742,974 acres and contains 117 whole OCS lease blocks as well as 20 partial blocks.

On February 6, 2012, BOEM published a Call for Information and Nominations for Commercial Leasing in the OCS offshore Massachusetts and a Notice of Intent to prepare an environmental assessment of this area. After considering numerous comments submitted in response to the Call, BOEM decided to exclude certain areas identified as important habitats that could be adversely affected if ultimately developed with the installation of wind turbine generators.

Specifically, BOEM has excluded an area of high sea duck concentration, as well as an area of high value fisheries to reduce conflict with commercial and recreational fishing activities. The fisheries exclusion area is a continuation of the Cox’s Ledge area excluded from leasing consideration in the Rhode Island/Massachusetts WEA announced on February 24, 2012. The excluded areas will not be considered further for leasing.

BOEM now will evaluate the WEA in an environmental assessment (EA), which will consider, among other things, potential impacts on endangered North Atlantic right whales and effects on viewshed. The EA also will consider mitigation measures that might reduce potential impacts on these and other resources in the WEA.

At this stage, BOEM is only considering the issuance of leases and approval of site assessment plans in this WEA. If, after leases are issued, a lessee proposes to construct a commercial wind energy facility, it would submit a construction and operations plan, at which point BOEM would prepare a site-specific NEPA document for the project proposed, including the lessee’s proposed transmission line(s) to shore.
