Pursuant to section 101(a)(5)(A) of the Marine Mammal Protection Act (MMPA) (16 U.S.C. 1361 et seq.), the National Marine Fisheries Service (NMFS), upon application from NMFS’ Northwest Fisheries Science Center (NWFSC), plans to propose regulations to govern the unintentional taking of marine mammals incidental to survey activities conducted in support of fisheries management. The proposed regulations would set forth the permissible methods of taking; means of effecting the least practicable adverse impact on the affected species or stocks and their habitats and, if applicable, on their availability for taking for subsistence uses (i.e., mitigation); and requirements pertaining to the monitoring and reporting of such taking. Letters of Authorization (LOAs) issued under the regulations would authorize the take of marine mammals incidental to the specified activities for a 5-year period.
