SUPPLEMENTARY INFORMATION:

Background

Section 101(a)(5)(A) of the MMPA (16 U.S.C. 1361 et seq.) directs the Secretary of Commerce to allow, upon request, the incidental, but not intentional taking of small numbers of marine mammals by U.S. citizens who engage in a specified activity (other than commercial fishing) within a specified geographical region if certain findings are made and regulations are issued.

Permission may be granted for periods of 5 years or less if NMFS finds that the taking will have no more than a negligible impact on the species or stock(s), and will not have an unmitigable adverse impact on the availability of the species or stock(s) for subsistence uses. In addition, NMFS must prescribe regulations that include permissible methods of taking and other means effecting the least practicable adverse impact on the species and its habitat, and on the availability of the species for subsistence uses, paying particular attention to rookeries, mating grounds, and areas of similar significance. The regulations must include requirements pertaining to the monitoring and reporting of such taking.

Regulations governing the taking of marine mammals incidental to the U.S. Navy's operation of SURTASS LFA sonar were published on July 16, 2002 (67 FR 46712), and remain in effect until August 15, 2007. For detailed information on this action, please refer to that document. These regulations include mitigation, monitoring, and reporting requirements for the incidental taking of marine mammals by the SURTASS LFA sonar system.

Summary of Request

On June 27, 2003, NMFS received an application from the U.S. Navy for two LOAs, each LOA covering one ship, under the regulations issued on July 16, 2002 (67 FR 46712). The Navy requested that the LOAs become effective on August 16, 2003. This application updated the information contained in the original application for an LOA dated August 12, 1999, and the revised application submitted on April 6, 2000, for takings of marine mammals by harassment incidental to deploying the SURTASS LFA sonar system for training, testing and routine military operations. The June 27, 2003, application requested authorization to take, by harassment, small numbers of marine mammals incidental to operation of the SURTASS LFA sonar system using the Research Vessel Cory Chouest and the USNS Impeccable, for a period not to exceed 1 year. The application's take estimates are based on 12 nominal 9-day active sonar missions (or equivalent shorter missions) among both vessels, regardless of which vessel is performing a specific mission, not to exceed a total of 432 hours of transmission time combined for both vessels.

The specified geographic regions identified in the application are the following oceanographic provinces described in Longhurst (1998) and identified in 50 CFR 216.180(a): the Archipelagic Deep Basins Province, the North Pacific Tropical Gyre (West) Province, and the North Pacific Tropical Gyre (East) Province, and the Western Pacific Warm Pool Province, all within the Pacific Trade Wind Biome; the Kuroshio Current Province, within the Pacific Westerly Winds Biome; the North Pacific Epicontinental Sea Province, within the Pacific Polar Biome; and the China Sea Coastal Province, within the North Pacific Coastal Biome. The Navy's operating areas, as identified in the application, are portions of the provinces but do not encompass the entire area of the provinces. Due to critical naval warfare requirements, the U.S. Navy has identified the necessity for both SURTASS LFA sonar vessels to be stationed in the North Pacific Ocean during fiscal year 2004.

Start Authority

Authority: Authorization

End Authority

Accordingly, NMFS issued two LOAs to the U.S. Navy on August 14, 2003 authorizing the taking, by harassment only, of small numbers of marine mammals incidental to operating the SURTASS LFA sonar system for training, testing and routine military operations. Issuance of these LOAs is based on findings, described in the preamble to the final rule (67 FR 46712, July 16, 2002), that the activities described in the two LOAs will result in the taking of no more than small numbers of marine mammals, and the total taking will have no more than a negligible impact on marine mammal stocks, and will not have an unmitigable adverse impact on the availability of the affected marine mammal stocks for subsistence uses. A copy of the LOAs and other cited documents are available at: http://www.nmfs.noaa.gov/​prot_​res/​PR2/​Acoustics_​Program/​Sound.htm#Sonar

These LOAs remain valid until August 15, 2004, provided the Navy is in conformance with the conditions of the regulations and the LOAs, and the mitigation, monitoring, and reporting requirements described in 50 CFR 216.184-216.186 (67 FR 46712, July 16, 2002) and in the LOAs are undertaken.
