NMFS Announces Regulations for Navy Training and Testing in Atlantic and Gulf of Mexico

The U.S. National Marine Fisheries Service has published final regulations requiring the United States Navy to implement protective measures during training and testing activities in the Atlantic Ocean and Gulf of Mexico to reduce effects on marine mammals.

The Navy requested an authorization under the Marine Mammal Protection Act, because the sound generated by active sonar, the sound and pressure generated by detonating explosives, and other associated activities could affect the behavior of some marine mammals, or cause a temporary loss of their hearing sensitivity or other injury.

The Navy’s current authorization expires in January 2014. The purpose of the Navy training and testing is to ensure the readiness of naval forces. Under the MMPA, this new authorization is limited to five years, and expires in November 2018.

NMFS recently made a final determination that the effects of these Navy operations would have a negligible impact on the overall species or stocks involved. Based on that final determination, NOAA Fisheries is requiring that the Navy use mitigation measures and, if properly followed, expects the exercises will not result in serious injury or death to a large number of marine mammals.

Under the authorization, the Navy will use the following mitigation measures to minimize effects on marine mammals, including:

  • establishing marine mammal mitigation zones around each vessel using sonar;
  • using Navy observers to shut down sonar operations if marine mammals are seen within designated mitigation zones;
  • using mitigation zones to ensure that explosives are not detonated when animals are detected within a certain distance;
  • implementing a stranding response plan that includes a training shutdown provision in certain circumstances, and allows for the Navy to contribute in-kind services to NOAA Fisheries if the agency has to conduct a stranding response and investigation; and,
  • using specific mitigation measures at certain times to reduce effects on North Atlantic right whales.

Additionally, the final rule includes an adaptive management component that requires that the Navy and NOAA Fisheries meet yearly to discuss new science, Navy research and development, and Navy monitoring results to determine if modifications to mitigation or monitoring measures are appropriate.
