{"abstract":"Upon application from Hilcorp Alaska, LLC (Hilcorp) and Eni US Operating Co. Inc.

These regulations allow NMFS to issue Letters of Authorization (LOA) for the incidental take of marine mammals during the specified construction and maintenance activities carried out during the rule's period of effectiveness, set forth the permissible methods of taking, set forth other means of effecting the least practicable adverse impact on marine mammal species or stocks and their habitat, and set forth requirements pertaining to the monitoring and reporting of the incidental take.","action":"Final rule; notification of issuance of Letters of
