NMFS, upon request from the Monterey Bay National Marine Sanctuary (MBNMS or Sanctuary), hereby issues regulations pursuant to the Marine Mammal Protection Act (MMPA) to govern the taking of marine mammals incidental to commercial fireworks displays permitted by the Sanctuary in California, over the course of five years (2017-2022). These regulations, which allow for the issuance of Letters of Authorization (LOA) for the incidental take of marine mammals during the described activities and specified timeframes, 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, and establish requirements pertaining to the monitoring and reporting of such taking.
