## 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 Federal waters of the U.S. Gulf of Mexico (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 an LOA to LLOG on January 10, 2022, for the take of marine mammals incidental to one of the following vertical seismic profile (VSP) survey types: Zero Offset, Offset, Walk Away, Salt Proximity and/or Check Shots after reaching total depth of any of the proposed wells operated by LLOG within the Keathley Canyon Area. Please see the                     **Federal Register**                     notice of issuance (87 FR 3084; January 20, 2022) for additional detail regarding the LOA and the survey activity.                

LLOG initially anticipated that the activity would occur at some point between March 1 and December 31, 2022. LLOG subsequently conveyed to NMFS that a shift in their rig schedule is likely to cause the associated VSP survey to occur later than previously expected. LLOG has requested modification to the effectiveness end date of the LOA (from December 31, 2022 to December 31, 2023) to account for any potential delays. There are no other changes to LLOG's planned activity. Since issuance of the LOA, no survey work has occurred.

## Authorization

                    NMFS has changed the effectiveness end date of the LOA from December 31, 2022 to December 31, 2023. There are no other changes to the LOA as described in the January 10, 2022,                     **Federal Register**                     notice of issuance (87 FR 3084): the specified activity; estimated take by incidental harassment; and small numbers analysis and determination remain unchanged and are herein incorporated by reference.                

Dated: July 7, 2022.

Kimberly Damon-Randall,

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