NMFS issues this final rule to implement measures contained in Framework 28 of the Northeast Multispecies Fishery Management Plan (FMP). This final rule allows the use, at specified times, of gillnets in areas otherwise closed to gillnet gear, provided they are equipped with pingers; removes the pinger specifications currently contained in the regulations and references the pinger specifications found in the Harbor Porpoise Take Reduction Plan (HPTRP); extends the Cape Cod South and Massachusetts Bay Closure Areas (March 1-March 30) to December 1- May 31; modifies the Mid-Coast Closure Area coordinates in the regulations to comport with those specified in the HPTRP; and replaces the framework adjustment procedure requiring the New England Fishery Management Council's (Council's) Harbor Porpoise Review Team to annually review harbor porpoise mortality goals with a procedure using the information and recommendations provided by the HPTRP's Harbor Porpoise Take Reduction Team. The intent of this action is to make the regulations to protect harbor porpoise in the Northeast multispecies fishery, issued under the authority of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson- Stevens Act) consistent, to the extent allowed by the Magnuson-Stevens Act, with the HPTRP and the regulations issued under the authority of the Marine Mammal Protection Act (MMPA) to implement the HPTRP.
