Takes of Marine Mammals Incidental to Specified Activities; Taking Marine Mammals Incidental to the SouthCoast Wind Project Offshore Massachusetts

NMFS received a request from SouthCoast Wind Energy LLC (SouthCoast) (formerly Mayflower Wind Energy LLC), for Incidental Take Regulations (ITR) and an associated Letter of Authorization (LOA) pursuant to the Marine Mammal Protection Act (MMPA). The requested regulations would govern the authorization of take, by Level A harassment and Level B harassment, of small numbers of marine mammals over the course of five years (2027-2032) incidental to construction of the SouthCoast Wind Project (SouthCoast Project) offshore of Massachusetts within the Bureau of Ocean Energy Management (BOEM) Commercial Lease of Submerged Lands for Renewable Energy Development on the Outer Continental Shelf (OCS) Lease Area OCS-A 0521 (Lease Area) and associated Export Cable Corridors (ECCs). Specified activities expected to result in incidental take are pile driving (impact and vibratory), unexploded ordnance or munitions and explosives of concern (UXO/MEC) detonation, and site assessment surveys using high-resolution geophysical (HRG) equipment. NMFS requests comments on this proposed rule. NMFS will consider public comments prior to making any final decision on the promulgation of the requested ITR and issuance of the LOA; agency responses to public comments will be summarized in the final rule. The regulations, if promulgated, would be effective April 1, 2027 through March 31, 2032.
