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 regulations.gov 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: https://www.boem.gov/Mayflower-Wind-Scoping-Virtual-Meetings.
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: www.permits.performance.gov/permitting-project/mayflower-wind-energy-project.

Mayflower Wind Energy LLC (OCS-A 0521)
On December 13-14, 2018, BOEM held a competitive lease sale (i.e., auction) for Wind Energy Areas offshore Massachusetts. The auction lasted 32 rounds. Equinor Wind US, LLC was identified as the winner of Lease Area OCS-A 0520 (128,811 acres), Mayflower Wind Energy, LLC was identified as the winner of Lease Area OCS-A 0521 (127,388 acres), and Vineyard Wind, LLC was identified as the winner of Lease Area OCS-A 0522 (132,370 acres).
The commercial wind energy lease OCS-A 0521 was by BOEM on March 26, 2019, and went into effect on April 1, 2019. The executed lease for OCS-A 0521 is available below.
A complete Site Assessment Plan (SAP) was submitted by Mayflower Wind Energy LLC to BOEM for meteorological evaluations and site assessment on December 12, 2019. BOEM approved the SAP on May 26, 2020. The plan details the methods and procedures Mayflower Wind Energy LLC will use to collect and analyze meteorological and oceanographic data and information on the conditions of the marine environment within its commercial lease. Data collection will be performed using a meteorological buoy. For additional information, please find the submitted SAP below:
