# 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 marine mammals by U.S. citizens who engage in a military readiness activity if certain findings are made and regulations are issued.                

Authorization may be granted for periods of 5 years or less if NMFS finds that the taking will have 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 certain 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 also 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 August 21, 2007 (72 FR 46846), and remain in effect through August 15, 2012. They are codified at 50 CFR part 216 subpart Q. 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 21, 2007                     **Federal Register**                     Notice and 50 CFR part 216 subpart Q.                

## Summary of LOA Request

                    NMFS received an application from the U.S. Navy for two LOAs, one covering the USNS ABLE (T-AGOS 20) and one covering the USNS IMPECCABLE (T-AGOS 23), under the regulations issued on August 21, 2007 (72 FR 46846). (The                     *R/V Cory Chouest*                     has been retired and has been replaced by the USNS ABLE.) The Navy requested that these LOAs become effective on August 16, 2008. The application requested authorization, for a period not to exceed 1 year, to take, by harassment, marine mammals incidental to employment of the SURTASS LFA sonar system for training, testing and routine military operations on the aforementioned ships in areas of the North Pacific Ocean.                

## Monitoring and Reporting

                    In compliance with NMFS' SURTASS LFA sonar regulations for the 2002-2007 period, the Navy submitted an annual report for SURTASS LFA sonar operations during 2006-2007. The Navy also submitted a comprehensive report on SURTASS LFA sonar operations and the mitigation and monitoring activities conducted under the LOAs issued under its previous rule. A copy of these reports can be viewed and/or downloaded at:                     *http://www.nmfs.noaa.gov/​pr/​permits/​incidental.htm#applications*. In accordance with the current SURTASS LFA sonar regulations (50 CFR 216.186), the Navy's has submitted classified quarterly mission reports, and its annual report for the 2007-2008 LOA is due on September 30, 2008. Upon receipt, NMFS will post this annual report on the same Internet address.                

## Authorization

NMFS has issued two LOAs to the U.S. Navy, authorizing the incidental harassment of marine mammals incidental to operating the two SURTASS LFA sonar systems for training, testing and routine military operations. Issuance of these two LOAs is based on findings, described in the preamble to the final rule (August 21, 2007, 72 FR 46846)) and supported by information contained in the Navy's required reports on SURTASS LFA sonar, that the activities described under these two LOAs 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.

These LOAs remain valid through August 15, 2009, 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 216.184-216.186 (August 21, 2007, 72 FR 46846) and in the LOAs are undertaken.

Dated: August 15, 2008.

Director, Office of Protected Resources, National Marine Fisheries Service.
