In accordance with the Marine Mammal Protection Act of 1972, as amended, the U.S. Fish and Wildlife Service (FWS) issues letters of authorization (LOA) for the nonlethal take of polar bears and Pacific walruses incidental to oil and gas industry exploration, development, and production activities in the Beaufort Sea and the adjacent northern coast of Alaska. The FWS also issues LOAs for the nonlethal take of northern sea otters incidental to pile driving and marine construction activities in the Gulf of Alaska. This notice announces the LOAs issued in calendar year 2024.

SUPPLEMENTARY INFORMATION:
On August 5, 2021, the U.S. Fish and Wildlife Service (FWS) published in the
Federal Register
a final rule (86 FR 42982) establishing regulations that allow us to authorize the nonlethal, incidental, unintentional take of small numbers of polar bears (
Ursus maritimus) and
( printed page 33981)
Pacific walruses (
Odobenus rosmarus divergens) during year-round oil and gas industry exploration, development, and production activities in the Beaufort Sea and adjacent northern coast of Alaska. These incidental take regulations are located in subpart J in part 18 of title 50 of the Code of Federal Regulations (CFR) and are effective through August 5, 2026. The rule prescribed a process under which we issue letters of authorization (LOA) to applicants conducting activities as described under the provisions of the regulations.
Each LOA stipulates conditions or methods that are specific to the activity and location. Holders of the LOAs must use methods and conduct activities in a manner that minimizes, to the greatest extent practicable, adverse impacts on Pacific walruses and polar bears and their habitat, and on the availability of these marine mammals for subsistence purposes. No intentional take or lethal incidental take is authorized under these regulations.
In accordance with section 101(a)(5)(A) of the Marine Mammal Protection Act (16 U.S.C. 1361et seq.) and our regulations at 50 CFR part 18, subpart J, in 2024, we issued LOAs to the companies in the Beaufort Sea and adjacent northern coast of Alaska shown in table 1.

On April 19, 2023, the FWS published in the
Federal Register
a final rule (88 FR 24115) establishing regulations that allow us to authorize the nonlethal, incidental, unintentional take of small numbers of northern sea otters (
Enhydra lutris kenyoni) during marine construction and pile-driving activities in coastal waters surrounding eight United States Coast Guard (USCG) facilities in the Gulf of Alaska. These incidental take regulations are located in subpart L in part 18 of title 50 of the CFR and are effective through May 19, 2028. The rule prescribed a process under which we issue LOAs to the USCG conducting activities as described under the provisions of the regulations.
Each LOA stipulates conditions or methods that are specific to the activity and location. Holders of the LOAs must use methods and conduct activities in a manner that minimizes, to the greatest extent practicable, adverse impacts on northern sea otters and their habitat, and on the availability of northern sea otters for subsistence purposes. No intentional take or lethal incidental take is authorized under these regulations.
In accordance with section 101(a)(5)(A) of the Marine Mammal Protection Act (16 U.S.C. 1361et seq.) and our regulations at 50 CFR part 18, subpart L, in 2024, we issued two LOAs to the USCG for their activities in the Gulf of Alaska, as shown in table 2.
