Mayflower Wind

BOEM kicked off the environmental review process November 1, 2021, with the publication of a Notice of Intent to prepare an Environmental Impact Statement (EIS) on Mayflower Wind Energy’s construction and operations plan.  The documents are available for viewing under the Construction & Operations tab above.

The publication in the Federal Register opened a 30-day comment, or scoping, period during which the public may identify information that the Environmental Impact Statement should consider.  The commenting period closed on December 1, 2021.  Posted comments can be viewed at on by searching for Docket No. BOEM-2021-0062.

Three virtual public meetings were held during the scoping period on November 10, 15 and 18, 2021.  For more information, please see:

Schedule for the Decision-making Process

After the draft EIS is completed, BOEM will publish a notice of availability (NOA) and request public comments on the draft EIS.  BOEM currently expects to issue the NOA in January 2023.  After the public comment period ends, BOEM will review and respond to comments received and will develop the final EIS.  BOEM currently expects to make the final EIS available to the public in September 2023.  A Record of Decision (ROD) will be completed no sooner than 30 days after the final EIS is released, in accordance with 40 CFR 1506.11.

This project is a “covered project” under section 41 of the Fixing America’s Surface Transportation Act (FAST-41).  FAST-41 provides increased transparency and predictability by requiring Federal agencies to publish comprehensive permitting timetables for all covered projects.  FAST-41 also provides procedures for modifying permitting timetables to address the unpredictability inherent in the environmental review and permitting process for significant infrastructure projects.  To view the FAST-41 Permitting Dashboard for the Project, visit:
