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 WesternGeco for the take of marine 
mammals incidental to geophysical survey activity in the GOM.

DATES: This LOA is effective through July 31, 2024.

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,

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 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 issued a LOA to WesternGeco on October 17, 2023, for the take 
of marine mammals incidental to a three-dimensional ocean bottom node 
survey in the Green Canyon and Walker Ridge protraction areas, 
including approximately 795 lease blocks, effective October 16, 2023, 
through April 30, 2024. Please see the Federal Register notice of 
issuance (88 FR 72739, October 23, 2023) for additional detail 
regarding the LOA and the survey activity.
    WesternGeco has requested a modification of the April 30, 2024, 
expiration date, extending it to July 31, 2024, due to survey delays. 
There are no other changes to WesternGeco's planned activity.

Authorization

    NMFS has changed the expiration date of the LOA from April 30, 
2024, to July 31, 2024. There are no other changes to the LOA as 
described in the October 23, 2023, Federal Register notice of issuance 
(88 FR 72739): the specified survey activity; estimated take by 
incidental harassment; and small numbers analysis and determination 
remain unchanged and are incorporated here by reference.

    Dated: April 23, 2024.

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