SUPPLEMENTARY INFORMATION:

The subject permit is requested under the authority of the Marine Mammal Protection Act of 1972, as amended (MMPA; 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 (ESA; 16 U.S.C. 1531 et seq.), and the regulations governing the taking, importing, and exporting of endangered and threatened species (50 CFR parts 222-226).

The applicant requests a five-year permit to study endangered Southern Resident killer whales (SRKW; Orcinus orca) in Washington State inland waters to identify important characteristics of prey fields (primarily chinook salmon, Oncorhynchus tshawytscha). Up to 714 takes of SRKW may occur annually by Level B harassment during marine vessel and aerial (unmanned aircraft system) based-research activities including photo-identification and other photography, video recording, acoustic exposure by echosounders for prey mapping, behavioral observations, focal follows, and tracking. Non-target species that may be taken during research include Transient killer whales, humpback ( Megaptera novaeangliae) and minke ( Balaenoptera acutorostrata) whales, Pacific white-sided dolphins ( Lagenorhynchus obliquidens), Dall's ( Phocoenoides dalli) and harbor ( Phocoena phocoena) porpoise, California ( Zalophus californianus) and Steller ( Eumetopias jubatus) sea lions, and harbor seals ( Phoca vitulina).

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.
