The National Marine Fisheries Service, of the U.S. National Oceanic and Atmospheric Administration, has requested comments on NMFS’ proposed issuance of an Incidental Harassment Authorization to take marine mammals to Quintillion Subsea Operations, LLC. This IHA would be effective during Quintillion’s subsea cable-laying operation in the state and federal waters of the Bering, Chukchi, and Beaufort seas, Alaska, during the open-water season of 2016. All takes authorized would be by Level B Harassments. NMFS proposes to issue this IHA pursuant to NMFS’s authority under the U.S. Marine Mammal Protection Act.
