## Background

                    NMFS published a final rule in the                     **Federal Register**                     on October 20, 2023 (88 FR 72562) announcing the promulgation of regulations governing the incidental take of marine mammals incidental to Revolution Wind, LLC's (Revolution Wind), construction of the Revolution Wind Offshore Wind Energy Project in Federal and State waters offshore Rhode Island, specifically 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-0486 and along two export cable routes to sea-to-shore transition points, valid for 5 years from the date of effectiveness.                

                    The regulations, which allow for the issuance of a Letter of Authorization to Revolution Wind for the incidental take of marine mammals during the specified activities within the specified geographical region during the effective dates of the regulations, prescribe the permissible methods of taking and other means of effecting the least practicable adverse impact on marine mammal species or stocks and their habitat, as well as requirements pertaining to the monitoring and reporting of such taking. NMFS refers the reader to the final rule (88 FR 72562, October 20, 2023) for background information concerning the regulations. The regulations contained a codification error requiring correction. Specifically, 50 CFR 217.274(b)(8) was promulgated twice (                    *i.e.,*                     two different measures were both designated as 217.274(b)(8), necessitating renumbering), and, therefore, a correction is necessary to properly number 50 CFR 217.274(b).                

## Correction

Effective November 20, 2023, in rule document 2023-22056 at 88 FR 72659 in the issue of October 20, 2023, on page 72662, in the first column, in amendatory instruction 2, paragraph (b) is corrected to read as follows:

§ 217.274

                            (b)                             *Vessel strike avoidance measures.*                             LOA Holder must comply with the following vessel strike avoidance measures, unless an emergency situation presents a threat to the health, safety, or life of a person or when a vessel, actively engaged in emergency rescue or response duties, including vessel-in-distress or environmental crisis response, requires speeds in excess of 10 kn (11.5 miles per hour (mph)) to fulfill those responsibilities, while in the specified geographical region:                        

                            (1) Prior to the start of the Project's activities involving vessels, LOA Holder must receive a protected species training that covers, at a minimum, identification of marine mammals that have the potential to occur where vessels would be operating; detection observation methods in both good weather conditions (                            *i.e.,*                             clear visibility, low winds, low sea states) and bad weather conditions (                            *i.e.,*                             fog, high winds, high sea states, with glare); sighting communication protocols; all vessel speed and approach limit mitigation requirements (                            *e.g.,*                             vessel strike avoidance measures); and information and resources available to the project personnel regarding the applicability of Federal laws and regulations for protected species. This training must be repeated for any new vessel personnel who join the Project. The dedicated visual observers must receive prior training on protected species detection and identification, vessel strike minimization procedures, how and when to communicate with the vessel captain, and reporting requirements in this subpart. Confirmation of the observers' training and understanding of the Incidental                                   ( print page 78675)                                Take Authorization (ITA) requirements must be documented on a training course log sheet and reported to NMFS;                        

(2) LOA Holder's vessels, regardless of their vessel's size, must maintain a vigilant watch for all marine mammals during all vessel operations and slow down, stop their vessel, or alter course to avoid striking any marine mammal;

                            (3) LOA Holder's underway vessels (                            *e.g.,*                             transiting, surveying) operating at any speed must have a dedicated visual observer on duty on each vessel at all times to monitor for marine mammals primarily within a 180° direction of the forward path of the vessel (90° port to 90° starboard) located at an appropriate vantage point for ensuring vessels are maintaining appropriate separation distances. Visual observers must be equipped with alternative monitoring technology (                            *e.g.,*                             night vision devices, infrared cameras) for periods of low visibility (                            *e.g.,*                             darkness, rain, fog,                             *etc.*). The dedicated visual observer must receive prior training on protected species detection and identification, vessel strike minimization procedures, how and when to communicate with the vessel captain, use of visual monitoring and alternative monitoring equipment, and reporting requirements in this subpart. Visual observers may be third-party observers (                            *i.e.,*                             NMFS-approved PSOs as defined in § 217.275 (a)(1)) or trained crew members;                        

(4) LOA Holder must continuously monitor the U.S. Coast Guard VHF Channel 16 at the onset of transiting through the duration of transiting, over which notifications of North Atlantic right whale Slow Zones (DMAs and acoustically-triggered Slow Zones) are broadcasted. At the onset of transiting and at least once every 4 hours, vessel operators and/or trained crew member(s) must also monitor the LOA Holder's Project-Wide Situational Awareness System, WhaleAlert, and relevant NOAA information systems such as the Right Whale Sighting Advisory System (RWSAS) for the presence of North Atlantic right whales;

                            (5) All LOA Holder's vessels must transit at 10 knots (11.5 mph) or less within any active North Atlantic right whale Seasonal Management Area (SMA) and Slow Zone (                            *i.e.,*                             Dynamic Management Areas (DMA) or acoustically-triggered Slow Zones);                        

(6) Between November 1 and April 30, all vessels, regardless of size, must operate port to port (specifically from ports in Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Virginia, and Maryland), and within the Lease Area and Revolution Wind Export Cable (RWEC) corridor, at 10 knots (11.5 mph) or less, except for vessels transiting in Narragansett Bay or Long Island Sound;

                            (7) All LOA Holder's vessel(s) (including crew transfer vessels) are restricted from traveling over 10 knots (11.5 mph), unless traveling in a frequently traveled transit corridor (                            *e.g.,*                             crew transfer corridor) between port to the Lease Area while LOA Holder monitors the transit corridor to detect large whales (including North Atlantic right whales) in real-time with PAM prior to and during transits. This measure only applies when no other vessel speed restrictions are in place;                        

(8) All LOA Holder's vessels, regardless of size, must immediately reduce speed to 10 knots (11.5 mph) or less for at least 24 hours when a North Atlantic right whale is sighted at any distance by any project-related personnel or acoustically detected by any project-related PAM system. Each subsequent observation or acoustic detection in the Project area must trigger an additional 24-hour period of operating at 10 knots (11.5 mph) or less. If a North Atlantic right whale is reported via any of the monitoring systems (see (b)(4) of this section) within 10 kilometers (km; 6.2 miles (mi)) of a transiting vessel(s), that vessel must operate at 10 knots (11.5 mph)) or less for 24 hours following the reported detection;

(9) LOA Holder's vessels, regardless of size, must immediately reduce speed to 10 knots (11.5 mph) or less when any large whale (other than a North Atlantic right whale) is observed within 500 meters (m; 1,640 ft) of an underway vessel;

(10) If a large whale (other than a North Atlantic right whale) is detected via the transit corridor PAM system, all vessels must travel at 10 knots (11.5 mph) until the whale can be confirmed visually beyond 500 m of the vessel or 24 hours has passed;

(11) LOA Holder's vessels must maintain a minimum separation distance of 500 m (1,640 ft) from North Atlantic right whales. If underway, all vessels must steer a course away from any sighted North Atlantic right whale at 10 knots (11.5 mph) or less such that the 500-m minimum separation distance requirement is not violated. If a North Atlantic right whale is sighted within 500 m of an underway vessel, that vessel must reduce speed and shift the engine to neutral. Engines must not be engaged until the whale has moved outside of the vessel's path and beyond 500 m. If a whale is observed but cannot be confirmed as a species other than a North Atlantic right whale, the vessel operator must assume that it is a North Atlantic right whale and take the vessel strike avoidance measures described in this paragraph;

(12) LOA Holder's vessels must maintain a minimum separation distance of 100 m (328 ft) from sperm whales and non-North Atlantic right whale baleen whales. If one of these species is sighted within 100 m of a transiting vessel, LOA Holder's vessel must reduce speed and shift the engine to neutral. Engines must not be engaged until the whale has moved outside of the vessel's path and beyond 100 m (328 ft);

                            (13) LOA Holder's vessels must maintain a minimum separation distance of 50 m (164 ft) from all delphinid cetaceans and pinnipeds with an exception made for those that approach the vessel (                            *i.e.,*                             bow-riding dolphins). If a delphinid cetacean that is not bow riding or a pinniped is sighted within 50 m of a transiting vessel, LOA Holder's vessel operator must shift the engine to neutral, with an exception made for those that approach the vessel (                            *e.g.,*                             bow-riding dolphins). Engines must not be engaged until the animal(s) has moved outside of the vessel's path and beyond 50 m (164 ft);                        

                            (14) When a marine mammal(s) is sighted while LOA Holder's vessel(s) is transiting, the vessel must not divert or alter course to approach any marine mammal and must take action as necessary to avoid violating the relevant separation distances (                            *e.g.,*                             attempt to remain parallel to the animal's course, slow down, and avoid excessive speed or abrupt changes in direction until the animal has left the area). If a separation distance is triggered, any vessel underway must avoid abrupt changes in course direction and take appropriate action as specified in paragraphs (b)(11) through (13) of this section. This measure does not apply to any vessel towing gear or any situation where respecting the relevant separation distance would be unsafe (                            *i.e.,*                             any situation where the vessel is navigationally constrained);                        

(15) LOA Holder is required to abide by other speed and approach regulations. Nothing in this subpart exempts vessels from any other applicable marine mammal speed and approach regulations;

                            (16) LOA Holder must check, daily, for information regarding the establishment of mandatory or voluntary vessel strike avoidance areas (                            *i.e.,*                             DMAs, SMAs, Slow Zones) and any information regarding North Atlantic right whale sighting locations;                        

                            (17) LOA Holder must submit a North Atlantic Right Whale Vessel Strike Avoidance Plan to NMFS Office of Protected Resources for review and                                   ( print page 78676)                                approval at least 90 days prior to the planned start of vessel activity. The plan must provide details on the vessel-based observer and PAM protocols for transiting vessels. If a plan is not submitted or approved by NMFS prior to vessel operations, all project vessels transiting, year round, must travel at speeds of 10 knots (11.5 mph) or less. LOA Holder must comply with any approved North Atlantic Right Whale Vessel Strike Avoidance Plan; and                        

(18) Speed over ground will be used to measure all vessel speed restrictions.
