Section 101(a)(5)(A) of the Marine Mammal Protection Act (MMPA; 16 U.S.C. 1361 et seq.) directs the Secretary of Commerce to allow, upon request, the incidental, but not intentional taking of marine mammals by U.S. citizens if certain findings are made and regulations are issued. Under the MMPA, the term “take” means to harass, hunt, capture, or kill or to attempt to harass, hunt, capture, or kill marine mammals. We, NMFS, have been delegated the authority to issue such regulations and Authorizations.
With respect to military readiness activities, the MMPA defines harassment as “(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]; Start Printed Page 49502or (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].
Authorization may be granted for periods of five years or less if we find that the total taking will have a negligible impact on the affected species or stock(s) and will not have an unmitigable adverse impact on the availability of the species or stock(s) for taking for certain subsistence uses. In addition, we must prescribe regulations that include permissible methods of taking and other means effecting the least practicable adverse impact on the species or stock and its habitat, paying particular attention to rookeries, mating grounds, and areas of similar significance, and on the availability of the species or stocks for taking for subsistence uses. The regulations also must include requirements pertaining to the monitoring and reporting of such taking.
Regulations governing the taking of marine mammals incidental to the Navy's routine training, testing, and military operations of SURTASS LFA sonar are in effect through August 15, 2017 (77 FR 50290, August 20, 2012) and are codified at 50 CFR part 218 subpart X. These regulations include mitigation, monitoring, and reporting requirements for the incidental taking of marine mammals by the SURTASS LFA sonar system. For detailed information on this action, please refer to the August 20, 2012, Federal Register Notice and 50 CFR part 218 subpart X. Under those regulations, we must publish a notice of issuance of an Authorization or Authorization renewal in the Federal Register within 30 days of a determination.
Summary of Request
On April 4, 2014, we received an application from the Navy requesting a renewal of four Authorizations, originally issued on August 15, 2012 (August 28, 2012) and renewed in 2013 (78 FR 57368, September 18, 2013), for the taking of marine mammals incidental to routine training, testing, and military operations of SURTASS LFA sonar in the northwest Pacific Ocean and the north-central Pacific Ocean under the regulations issued on August 15, 2012 (77 FR 50290, August 20, 2012): one for the United States Naval Ship (USNS) VICTORIOUS (T-AGOS 19), one for the USNS ABLE (T-AGOS 20), one for the USNS EFFECTIVE (T-AGOS 21), and one for the USNS IMPECCABLE (T-AGOS 23) The application requested that these four Authorizations become effective on August 15, 2014, for a period not to exceed one year.
Summary of Activity Under the 2013 Authorizations
The Navy submitted quarterly mission reports for the periods of August 2013 through May 2014 within the required timeframes. These quarterly reports include the dates and times of the military readiness activities; location of each SURTASS LFA sonar vessel; mission operational area; marine mammal observations; and records of any delays or suspensions of sonar operations. The Navy must also report on the number of marine mammals detected by visual, passive and active acoustic monitoring and the estimated percentage of each marine mammal stock taken by Level A and Level B harassment. The reports indicate the following:
- The Navy conducted a total of 5 missions from August 15, 2013, through May 14, 2014, in the western North Pacific Ocean, which totaled 15.14 days and resulted in 29.3 hours of LFA sonar transmissions.
- The cumulative total days of SURTASS LFA sonar operations for the ABLE, EFFECTIVE, IMPECCABLE, and VICTORIOUS were 97, 98, 100, and 98 percent below the annual levels contemplated in the Final Rule for each vessel respectively (i.e., 240 days per vessel);
- The cumulative total hours of SURTASS LFA sonar transmissions for the ABLE, EFFECTIVE, IMPECCABLE, and VICTORIOUS were 97, 98, 100, and 98 percent below the levels contemplated in the Final Rule for each vessel respectively (i.e., 432 hours per vessel);
- The total percentage of each marine mammal stock taken by Level B harassment has not exceeded the 12 percent cap. For each stock, the percentage of take was well below the levels authorized in the 2013 Authorizations.
- The total percentage of each marine mammal stock taken by Level A harassment has not exceeded the levels authorized in the 2013 Authorizations. In fact, the Navy reported no incidences of Level A harassment takes.
The operational tempo, number of active transmission hours, marine mammal detections and behavioral observations, and level of anticipated take of marine mammals fall within the scope and nature of those contemplated by the Final Rule and authorized in the 2013 Authorizations.
The Navy has submitted the monitoring reports on time as required under 50 CFR 218.236 and the 2013 Authorizations. We have reviewed these reports and determined them to be acceptable. Based on these reports, the Navy has not exceeded the average annual estimated usage of the four SURTASS LFA sonar systems and remains well within the take authorized. In accordance with the current SURTASS LFA sonar regulations (50 CFR 218.230), the Navy must submit an annual report to us no later than 45 days after the 2013 Authorizations have expired. Upon receipt, we will post the annual report at: http://www.nmfs.noaa.gov/pr/permits/incidental.htm#applications.
Level of Taking for 2014 Authorizations Period
For the 2014 to 2015 Authorization period, the Navy expects to conduct the same type and amount of routine training, testing, and military operations of SURTASS LFA sonar in the northwest Pacific Ocean and the north-central Pacific Ocean that they requested under the 2012 and 2013 Authorizations. Similarly, the Navy expects to remain within the annual take estimates analyzed in the Final Rule. We determined that the level of taking by incidental harassment from the activities described in the Authorizations and supporting application is consistent with the findings made for the total taking allowable under the 2012 Final Rule.
Compliance With Mitigation, Monitoring, and Reporting Measures
Based on our review of the Navy's quarterly mission reports, the Navy complied with the required visual, passive, and acoustic monitoring measures in the Final Rule and 2013 Authorizations. The Navy also followed the required shutdown and other protocols for mitigating impacts to marine mammals while conducting operations.
The Navy is also complying with required measures under 50 CFR 218.236(d) to gain and share information on the species. The Navy reports that they are continuing to work on information transfer, declassification and archiving of ambient noise data from the Navy's Integrated Undersea Surveillance System (IUSS) to the public.
The Final Rule and 2012 Authorizations required the Navy to Start Printed Page 49503convene a Scientific Advisory Group (SAG) to analyze different types of monitoring and research that could increase the understanding of the potential effects of LFA sonar on beaked whales and harbor porpoises (50 CFR 218.236(e)).
In March 2013, the Navy convened a SAG—comprised of subject matter experts in marine acoustics, bioacoustics, behavioral response studies, and the biology/behavior of beaked whales and porpoises— and tasked them with: summarizing our understanding of the likely impacts of SURTASS LFA sonar operations on these species; gathering information on various scientific and monitoring tools that could potentially be used to better understand these effects; and evaluating the feasibility and cost of these tools. In August 2013, NMFS received the SAG's final report titled, Potential Effects of SURTASS LFA Sonar on Beaked Whales and Harbor Porpoises: Final Report which presented recommendations on the feasibility, efficacy, and significance of any proposed research projects that would increase the understanding of the potential effects of LFA sonar on beaked whales and harbor porpoises.
In February 2014, the SAG's Executive Oversight Group (EOG) comprised of members from the Navy and NMFS, met to assess and discuss the conclusions and proposed research approaches in the SAG's final report. The goal of the meeting was to develop a plan of action recommending monitoring and research efforts that the Navy could implement to study the potential effects of SURTASS LFA on beaked whales and harbor porpoises. The meeting, EOG discussions, and development of an action plan will assist the Navy in fulfilling its responsibilities under the Final Rule for beaked whale and harbor porpoise monitoring and section 12(a) of the annual LOAs. The Navy has considered the SAG final report's assessments and continues to develop an appropriate plan of action for new monitoring and/or research and submit to NMFS in the near future. The EOG will meet again in Fall 2014 to agree on the best research or monitoring recommendations for each taxa and develop a plan of action recommending how the Navy should carry out future research.
Based on the foregoing information and the Navy's application, we determined that the mitigation, monitoring, and reporting measures required under 50 CFR 218.234, .235, and .236 and NMFS' 2013 Authorizations were undertaken and will be undertaken during the period of validity of the renewed 2014 Authorizations.
The Final Rule and 2013 Authorizations include an adaptive management framework that allows us to consider new information and to determine (with input from the Navy regarding practicability) if modifications to mitigation and/or monitoring measures are appropriate and practicable. This framework includes a requirement for an annual meeting between us and the Navy, if either agency deems it necessary.
Section 218.241 of the Final Rule describes three scenarios that could contribute to the decision to modify the mitigation or monitoring measures, including: (a) Results from the Navy's monitoring from the previous year's operation of SURTASS LFA sonar; (b) compiled results of Navy-funded research and development studies; (c) results from specific stranding investigations; (d) results from general marine mammal and sound research funded by the Navy or other sponsors; and (e) any information that reveals marine mammals may have been taken in a manner, extent or number not anticipated by these regulations or subsequent Authorizations. None of the information reviewed by NMFS or the Navy resulted in any modifications to the existing mitigation or monitoring measures at this time.
Consideration of Areas as Potential OBIAs
We intend to evaluate new information relating to several areas for potential consideration as OBIAs for mysticetes and/or sperm whales before the Navy submits their 2015 renewal request for Authorizations under the Final Rule. All of these areas fall outside the areas in which the Navy may operate under the 2014 Authorizations. Our evaluation will include the following areas:
- Atlantic Ocean: Southeast Shoal-Grand Banks, Canada; Grand Manan Basin Right Whale Conservation Area, Canada; Jordan Basin-Gulf of Maine, U.S.; Challenger Bank, Bermuda; and nearshore waters offshore New Jersey, U.S.
- Gulf of Mexico: areas in the eastern Gulf of Mexico, U.S.; Mississippi and DeSoto Canyons, U.S.
- Indian Ocean: Masira Bay, Oman and the Geyser-Zelee Complex, Madagascar.
- North Sea: Dogger Bank, Germany.
- Mediterranean Sea: central Tyrrhenian Sea and areas in the northern Mediterranean Sea.
- Pacific Ocean: South Taranaki Bight, New Zealand; the Coral Sea Commonwealth Marine Reserve, Australia; and the proposed expanded areas of the Gulf of the Farallones and Cordell Bank National Marine Sanctuaries, U.S.
None of these areas is located within the Navy's mission areas for the 2014 Authorizations and the Navy will not operate SURTASS LFA sonar in these areas within the timeframes of the 2014-2015 Authorizations. We will evaluate these areas further as a potential OBIAs with input from the Navy regarding practicability, as necessary through the adaptive management process, for the Navy's 2015 Authorization requests. Throughout the effective period of the Final Rule, we will consider and discuss with the Navy any relevant new information as it arises related to areas that may qualify as potential OBIAs or any other mitigation for SURTASS LFA sonar.
We have issued four Authorizations to the Navy, authorizing the incidental harassment of marine mammals, incidental to operating the four SURTASS LFA sonar systems for routine training, testing and use during military operations. Issuance of these four Authorizations is based on findings, described in the preamble to the final rule (77 FR 50290, August 20, 2012) and supported by information contained in the Navy's required reports on SURTASS LFA sonar and their application, that the activities described under these four Authorizations will have a negligible impact on marine mammal species or stocks and will not have an unmitigable adverse impact on their availability for taking for subsistence uses.
These Authorizations remain valid through August 14, 2015, provided the Navy remains in conformance with the conditions of the regulations and the LOAs, and the mitigation, monitoring, and reporting requirements described in 50 CFR 218.230 through 218.241 (77 FR 50290, August 20, 2012) and in the Authorizations are undertaken.
