Notice; receipt of application for a Letter of Authorization; request for comments and information.


NMFS has received a request from the U.S. Navy (Navy) for authorization to take marine mammals incidental to training and testing activities conducted in the Mariana Islands Training and Testing (MITT) Study Area for a period of seven years, from August, 2020 through August, 2027. Pursuant to regulations implementing the Marine Mammal Protection Act (MMPA), NMFS is announcing receipt of the Navy's request for the development and implementation of regulations governing the incidental taking of marine mammals. NMFS invites the public to provide information, suggestions, and comments on the Navy's application and request.


Comments and information must be received no later than April 15, 2019.

Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et seq.) direct the Secretary of Commerce (Secretary) to allow, upon request, the incidental, but not intentional taking of marine mammals by U.S. citizens who engage in a specified activity (other than commercial fishing) within a specified geographic region if certain findings are made and either regulations are issued or, if the taking is limited to harassment, notice of a proposed authorization is provided to the public for review.

An authorization for incidental takings 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 takings 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 MMPA states that the term “take” means to harass, hunt, capture, kill or attempt to harass, hunt, capture, or kill any marine mammal.

Except with respect to certain activities not pertinent here, the MMPA defines “harassment” as: Any act of pursuit, torment, or annoyance which (i) has the potential to injure a marine mammal or marine mammal stock in the wild (Level A harassment); or (ii) has the potential to disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns, including, but not limited to, migration, breathing, nursing, breeding, feeding, or sheltering (Level B harassment).

The National Defense Authorization Act for Fiscal Year 2004 (Pub. L. 108-136) removed the “small numbers” and “specified geographical region” limitations indicated above 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). On August 13, 2018, the 2019 NDAA (Pub. L. 115-232) amended the MMPA to allow incidental take regulations for military readiness activities to be issued for up to seven years.

Summary of Request

On February 11, 2019, NMFS received an adequate and complete application from the Navy requesting authorization for the take of marine mammals, by Level A and B harassment, incidental to training, testing, and routine military operations (all categorized as military readiness activities) from the use of sonar and other transducers and in-water detonations. The requested regulations will be valid for seven years, from 2020 through 2027.

This will be the third time NMFS has promulgated incidental take regulations pursuant to the MMPA relating to similar military readiness activities in the MITT Study Area, following those effective from August 3, 2010, through August 3, 2015, (75 FR 45527; August 3, 2010) and from August 3, 2015 through August 3, 2020 (80 FR 46112; August 3, 2015).

Description of the Specified Activity

The MITT Study Area is comprised of three components: (1) The Mariana Islands Range Complex (MIRC), (2) additional areas on the high seas, and (3) a transit corridor between the MIRC and the Hawaii Range Complex (HRC) (see Figure 1.1-1 of the application). The transit corridor is outside the geographic boundaries of the MIRC and represents a great-circle route across the high seas for Navy ships transiting between the MIRC and the HRC. The proposed activities also includes various operations in Apra Harbor such as sonar maintenance and testing alongside Navy piers located in Inner Apra Harbor.

The following types of training and testing, which are classified as military readiness activities pursuant to section 315(f) of Public Law 101-314 (16 U.S.C. 703), are included in the specified activity described in the Navy's application: Amphibious warfare (in-water detonations), anti-submarine warfare (sonar and other transducers, in-water detonations), surface warfare (in-water detonations), and other (sonar and other transducers).

The Navy's application includes proposed mitigation measures for marine mammals that would be implemented during training and testing activities in the MITT Study Area. Proposed procedural mitigation measures generally include: (1) The use of Lookouts to observe for biological resources and communicate the need for mitigation implementation; (2) powerdowns, shutdowns, and delay of starts to avoid exposure of marine mammals to high levels of sound or explosive blasts more likely to result in injury or more serious behavioral disruption; and (3) limiting the use of active sonar or explosives in certain biologically important areas to reduce the probability or severity of impacts when they are more likely to contribute to fitness impacts.

The Navy also proposes to undertake monitoring and reporting efforts to track compliance with incidental take authorizations and to help investigate the effectiveness of implemented mitigation measures in the MITT Study Area. This can include Adaptive Start Printed Page 9497Management, the Integrated Comprehensive Monitoring Program, the Strategic Planning Process, and Annual Monitoring and Exercise and Testing Reports. As an example, under the Integrated Comprehensive Monitoring Program, the monitoring relating to the effects of Navy training and testing activities on protected marine species are designed to increase the understanding of the likely occurrence of marine mammals in the vicinity of the action (i.e., presence, abundance, distribution, and density of species) and to increase the understanding of the nature, scope, or context of the likely exposure of marine mammals to any of the potential stressors associated with the action.

Information Solicited

Interested persons may submit information, suggestions, and comments concerning the Navy's request (see ADDRESSES). NMFS will consider all information, suggestions, and comments related to the request during the development of proposed regulations governing the incidental taking of marine mammals by the Navy, if appropriate.
