NMFS Issues IHA for Elgin Air Force Base

The U.S. National Marine Fisheries has issued an Incidental Harassment Authorization to the U.S. Air Force, Eglin Air Force Base, to take two species of marine mammals, the Atlantic bottlenose dolphin (Tursiops truncatus) and Atlantic spotted dolphin (Stenella frontalis), by harassment, incidental to a Maritime Weapon Systems Evaluation Program within the Eglin Gulf Test and Training Range in the Gulf of Mexico from February 4, 2016 through February 3, 2017. NMFS has issued this IHA under the U.S. Marine Mammal Protection Act.

The MMPA directs the Secretary of Commerce to allow, upon request, the incidental, but not intentional, taking of small numbers of marine mammals of a species or population stock, by U.S. citizens who engage in a specified activity (other than commercial fishing) within a specified geographical region if, after NMFS provides a notice of a proposed authorization to the public for review and comment: (1) NMFS makes certain findings; and (2) the taking is limited to harassment.

An Authorization for incidental takings for marine mammals 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 taking 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 National Defense Authorization Act of 2004 (NDAA; Pub. L. 108–136) removed the ‘‘small numbers’’ and ‘‘specified geographical region’’ limitations indicated earlier and amended the definition of harassment as it applies to a ‘‘military readiness activity’’ to read as follows (Section 3(18)(B) of the MMPA): (i) Any act that injures or has the significant potential to injure a marine mammal or marine mammal stock in the wild [Level A Harassment]; or (ii) any act that disturbs or is likely to disturb a marine mammal or marine mammal stock in the wild by causing disruption of natural behavioral patterns, including, but not limited to, migration, surfacing, nursing, breeding, feeding, or sheltering, to a point where such behavioral patterns are abandoned or significantly altered [Level B Harassment].
