Marine Mammals; Incidental Take During Specified Activities

The Fish and Wildlife Service (Service or we) has developed regulations that authorize the nonlethal, incidental, unintentional take of small numbers of Pacific walruses (Odobenus rosmarus divergens) and polar bears (Ursus maritimus) during oil and gas industry (Industry) exploration activities in the Chukchi Sea and adjacent western coast of Alaska. This rule will be effective for 5 years from date of issuance. We find that the total expected takings of Pacific walruses (walruses) and polar bears during Industry exploration activities will impact small numbers of animals, will have a negligible impact on these species, and will not have an unmitigable adverse impact on the availability of these species for subsistence use by Alaska Natives. The regulations include: permissible methods of nonlethal taking; measures to ensure that Industry activities will have the least practicable adverse impact on the species and their habitat, and on the availability of these species for subsistence uses; and requirements for monitoring and reporting. The Service will issue Letters of Authorization (LOAs) to conduct activities under the provisions of these regulations.
