The US Bureau of Ocean Energy Management (BOEM) has affirmed the issuance of a lease for the 468MW Cape Wind offshore project off the US east coast, following assessment of a supplemental environmental impact statement (SEIS).

The supplement to the 2009 final EIS was prepared in response to a 2016 order from the US Court of Appeals for the District of Columbia to provide more adequate geological surveys of the project site.

The SEIS contained additional data gathered by Cape Wind since the 2009 EIS was issued. BOEM concluded that the new data does not change the previous assessment that the project design is suitable for turbine construction given the seabed conditions.

“There is no evidence to suggest the seafloor would be unable to support turbines for this project design,” BOEM said.

The Bureau was responsible for carrying out the impact assessment for the project.

BOEM’s decision also affirms the construction and operations plan, which allows Cape Wind to build 130 turbines in a 12,000-hectare area between Cape Cod, Martha’s Vineyard and Nantucket Island.

Cape Wind was first proposed more than a decade ago but has been held up by a series of regulatory, legal and financing challenges.
