This site displays a prototype of a “Web 2.0” version of the daily
Federal Register. It is not an official legal edition of the Federal

The documents posted on this site are XML renditions of published Federal
Register documents. Each document posted on the site includes a link to the

daily Federal Register on FederalRegister.gov will remain an unofficial
informational resource until the Administrative Committee of the Federal
Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

SUPPLEMENTARY INFORMATION:
Background
Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361et seq.) direct the Secretary of Commerce (as delegated to NMFS) 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 incidental take authorization 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. The MMPA states that the term “take” means to harass, hunt, capture, kill or attempt to harass, hunt, capture, or kill any marine mammal.
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).
Summary of Request
On October 30, 2024, NMFS received an application from Hilcorp requesting authorization for take of marine mammals incidental to oil and gas exploration, development, production, and decommissioning activities in Cook Inlet, Alaska. NMFS determined that the application was adequate and complete on February 10, 2024. The requested regulations would be valid for five years, from the date of issuance through December 31, 2029. Hilcorp plans to conduct necessary work, including tugs towing, holding, or positioning a jack-up rig, pile driving, and pipeline replacement/installation activities. The exposure of marine mammals occurring in the vicinity to underwater noise generated by the activities could result in incidental take, by Level A and Level B harassment. Therefore, Hilcorp requests authorization to incidentally take marine mammals.
( printed page 11952)
Specified Activities
Hilcorp plans to continue oil and gas exploration, development, production, and decommissioning activities in Cook Inlet, Alaska, for the reasonably foreseeable future. The work expected to span five years includes up to 54 days of tugs towing, holding, or positioning a jack-up rig in support of production drilling at existing platforms in middle Cook Inlet and Trading Bay; up to 70 days of pile driving in support of production well development at the Tyonek platform in middle Cook Inlet; up to 6 days of tugs towing, holding, or positioning a jack-up rig and up to 18 days of pile driving in support of exploration drilling at two locations in the Middle Ground Shoal Unit in middle Cook Inlet and one location between the Anna and Bruce platforms on the northern border of Trading Bay; and up to 22 days of pipeline replacement/installation, involving either pipe pulling or anchor handling or a combination of both, at up to two locations in middle Cook Inlet and/or Trading Bay. Hilcorp requests take of marine mammals by Level B harassment for twelve marine mammal species (including Cook Inlet beluga whales (
Delphinapterus leucas)), and take by Level A harassment of nine marine mammal species.
Information Solicited
Interested persons may submit information, suggestions, and comments concerning the Hilcorp's request (see
ADDRESSES
). NMFS will consider all information, suggestions, and comments related to the request during the development of proposed regulations governing the incidental taking of marine mammals by Hilcorp, if appropriate.
