Taking and Importing Marine Mammals; Taking Marine Mammals 
Incidental to Geophysical Surveys Related to Oil and Gas Activities in 
the Gulf of Mexico

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Notice of modification to expiration date of letter of 
authorization.

-----------------------------------------------------------------------

SUMMARY: In accordance with the Marine Mammal Protection Act (MMPA), as 
amended, its implementing regulations, and NMFS' MMPA Regulations for 
Taking Marine Mammals Incidental to Geophysical Surveys Related to Oil 
and Gas Activities in the Gulf of Mexico (GOM), notification is hereby 
given that NMFS has modified the expiration date of a Letter of 
Authorization (LOA) issued to Murphy Exploration and Production Company 
(Murphy) for the take of marine mammals incidental to geophysical 
survey activity in the GOM.

DATES: This LOA is effective through March 15, 2025.

ADDRESSES: The LOA, LOA request, and supporting documentation are 
available online at: https://www.fisheries.noaa.gov/marine-mammal-protection/issued-letters-authorization-oil-and-gas-industry-geophysical-survey. In case of problems accessing these documents, 
please call the contact listed below (FOR FURTHER INFORMATION CONTACT).

Resources, NMFS, (301) 427-8401.

SUPPLEMENTARY INFORMATION:

Background

    Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et seq.) 
direct the Secretary of Commerce to allow, upon request, the 
incidental, but not intentional, taking of small numbers of

[[Page 92907]]

marine mammals by U.S. citizens who engage in a specified activity 
(other than commercial fishing) within a specified geographical region 
if certain findings are made and either regulations are issued or, if 
the taking is limited to harassment, a notice of a proposed 
authorization is provided to the public for review.
    An authorization for incidental takings shall be granted if NMFS 
finds that the taking will have a negligible impact on the species or 
stock(s), will not have an unmitigable adverse impact on the 
availability of the species or stock(s) for subsistence uses (where 
relevant), and if the permissible methods of taking and requirements 
pertaining to the mitigation, monitoring and reporting of such takings 
are set forth. NMFS has defined ``negligible impact'' in 50 CFR 216.103 
as an impact resulting from the specified activity that cannot be 
reasonably expected to, and is not reasonably likely to, adversely 
affect the species or stock through effects on annual rates of 
recruitment or survival.
    Except with respect to certain activities not pertinent here, the 
MMPA defines ``harassment'' as: any act of pursuit, torment, or 
annoyance which: (i) has the potential to injure a marine mammal or 
marine mammal stock in the wild (Level A harassment); or (ii) has the 
potential to disturb a marine mammal or marine mammal stock in the wild 
by causing disruption of behavioral patterns, including, but not 
limited to, migration, breathing, nursing, breeding, feeding, or 
sheltering (Level B harassment).
    On January 19, 2021, we issued a final rule with regulations to 
govern the unintentional taking of marine mammals incidental to 
geophysical survey activities conducted by oil and gas industry 
operators, and those persons authorized to conduct activities on their 
behalf (collectively ``industry operators''), in U.S. waters of the GOM 
over the course of 5 years (86 FR 5322, January 19, 2021). The rule was 
based on our findings that the total taking from the specified 
activities over the 5-year period will have a negligible impact on the 
affected species or stock(s) of marine mammals and will not have an 
unmitigable adverse impact on the availability of those species or 
stocks for subsistence uses. The rule became effective on April 19, 
2021.
    Our regulations at 50 CFR 217.180 et seq. allow for the issuance of 
LOAs to industry operators for the incidental take of marine mammals 
during geophysical survey activities and prescribe the permissible 
methods of taking and other means of effecting the least practicable 
adverse impact on marine mammal species or stocks and their habitat 
(often referred to as mitigation), as well as requirements pertaining 
to the monitoring and reporting of such taking. Under 50 CFR 
217.186(e), issuance of an LOA shall be based on a determination that 
the level of taking will be consistent with the findings made for the 
total taking allowable under these regulations and a determination that 
the amount of take authorized under the LOA is of no more than small 
numbers.
    NMFS subsequently discovered that the 2021 rule was based on 
erroneous take estimates. We conducted another rulemaking using correct 
take estimates and other newly available and pertinent information 
relevant to the analyses supporting some of the findings in the 2021 
final rule and the taking allowable under the regulations. We issued a 
final rule in April 2024, effective May 24, 2024 (89 FR 31488, April 
24, 2024).
    The 2024 final rule made no changes to the specified activities or 
the specified geographical region in which those activities would be 
conducted, nor to the original 5-year period of effectiveness. In 
consideration of the new information, the 2024 rule presented new 
analyses supporting affirmance of the negligible impact determinations 
for all species, and affirmed that the existing regulations, which 
contain mitigation, monitoring, and reporting requirements, are 
consistent with the ``least practicable adverse impact'' (LPAI) 
standard of the MMPA.
    NMFS issued a LOA to Murphy on March 20, 2024, for the take of 
marine mammals incidental to a three-dimensional (3D) ocean bottom node 
survey in the Green Canyon protraction areas, including approximately 
44 lease blocks, effective April 1, 2024, through October 31, 2024. 
Please see the Federal Register notice of issuance (89 FR 20946, March 
26, 2024) for additional detail regarding the LOA and the survey 
activity.
    Murphy subsequently requested, and NMFS issued, a modification to 
the LOA expiration date, extending it to January 31, 2025 (89 FR 83464, 
October 16, 2024). On November 1, 2024 Murphy informed NMFS that the 
survey had further delays, and requested a second modification to the 
expiration date of the LOA (from December 31, 2025 to March 15, 2025) 
to accommodate the delays. There are no other changes to Murphy's 
planned activity.

Authorization

    NMFS has changed the expiration date of the LOA from January 31, 
2025 to March 15, 2025. There are no other changes to the LOA as 
described in the October 16, 2024, Federal Register notice of issuance 
(89 FR 83464): the specified survey activity, estimated take by 
incidental harassment, and small numbers analysis and determination 
remain unchanged and are referenced in this notice.

    Dated: November 19, 2024.

Director, Office of Protected Resources, National Marine Fisheries 
Service.
