National security requirement. Should national security require the Action Proponents to exceed a requirement(s) in paragraphs (a)(2)(i) through (ix) of this section, Action Proponent personnel must provide NMFS with advance notification and include the information (e.g., sonar hours, explosives usage, or restricted area use) in its annual activity reports submitted to NMFS.

(3)

Cetacean live stranding. In the event of a cetacean live stranding (or near-shore atypical milling) event within the AFTT Study Area or within 50 km (27 nmi) of the boundary of the AFTT Study Area, where the NMFS Stranding Network is engaged in herding or other interventions to return marine mammals to the water, NMFS Office of Protected Resources will advise the Action Proponents of the need to implement shutdown procedures for all active acoustic sources or explosive devices within 50 km of the stranding. Following this initial shutdown, NMFS will communicate with the Action Proponents to determine whether circumstances support modification of the shutdown zone. The Action Proponents may decline to implement all or part of the shutdown if the holder of the LOA, or his/her designee, determines that it is necessary for national security. Shutdown procedures for live stranding or milling cetaceans include the following:

(i)

Shutdown no longer needed. If at any time, the marine mammal(s) die or are euthanized, or if herding/intervention efforts are stopped, NMFS will immediately advise that the shutdown around the marine mammals' location is no longer needed;

(ii)

Shutdown procedures remain in effect. Otherwise, shutdown procedures will remain in effect until NMFS determines and advises that all live marine mammals involved have left the area (either of their own volition or following an intervention); and

(iii)

Further observations. If further observations of the marine mammals indicate the potential for re-stranding, additional coordination will be required to determine what measures are necessary to minimize that likelihood (e.g., extending the shutdown or moving operations farther away) and to implement those measures as appropriate.

(4)

North Atlantic right whale persistence. Within the first year of effectiveness of the LOA(s), the Action Proponents shall work collaboratively with the NMFS Endangered Species Act Interagency Cooperation Division and the NMFS Permits and Conservation Division to:

(1)

Analyze and discuss the application of new information from the NMFS North Atlantic Right Whale Persistence Modelling Efforts toward AFTT mitigation measures;

(2)

Evaluate the practicability and conservation benefits of newly proposed mitigation measure and/or changes to existing measures based on information from the model; and

(3)

Implement any new mitigation measures or changes to existing measures that meet the Action Proponents' Practicability Criteria and Sufficiently Beneficial requirements.
