**SUPPLEMENTARY INFORMATION:**
The subject permit is requested under the authority of the Marine Mammal Protection Act of 1972, as amended (16 U.S.C. 1361 *et seq.* ), the regulations governing the taking and importing of marine mammals (50 CFR part 216), the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 *et seq.* ), the regulations governing the taking, importing, and exporting of endangered and threatened species (50 CFR parts 222-226), and the Fur Seal Act of 1966, as amended (16 U.S.C. 1151 *et seq.* ).
The applicant requests a 10-year permit to conduct research in Alaska on 15 species of marine mammals including the following endangered species: blue whale ( *Balaenoptera musculus* ); fin whale ( *B. physalus* ); gray whale ( *Eschrichtius robustus* ); humpback whale ( *Megaptera novaeangliae* ); North Pacific right whale ( *Eubalaena japonica* ); sei whale ( *B. borealis* ); sperm whale ( *Physeter microcephalus* ); and Steller sea lion ( *Eumetopias jubatus* ). The objectives are to advance knowledge and improve understanding of the foraging behavior, prey use, and habitat of marine mammals. Target cetaceans may be taken during vessel surveys for counts, photography and video recording, photo-identification, behavioral observations, active acoustic sonar for prey mapping, and biological sampling (feces, sloughed skin, predation remains, and skin and blubber biopsies). Non-target cetaceans and pinnipeds may be unintentionally harassed and opportunistically studied during research. See the application for complete numbers of animals requested by species, life stage, and procedure.
In compliance with the National Environmental Policy Act of 1969 (42 U.S.C. 4321 *et seq.* ), an initial determination has been made that the activity proposed is categorically excluded from the requirement to prepare an environmental assessment or environmental impact statement.
Concurrent with the publication of this notice in the *Federal Register* , NMFS is forwarding copies of the application to the Marine Mammal Commission and its Committee of Scientific Advisors.
