ACTION:

Notice of issuance of a Letter of Authorization.

SUMMARY:

In accordance with the Marine Mammal Protection Act (MMPA), as amended, and implementing regulations, notification is hereby given that a letter of authorization (LOA) has been issued to the 30th Space Wing, U.S. Air Force, to take four species of seals and sea lions incidental to rocket and missile launches on Vandenberg Air Force Base (VAFB), California, a military readiness activity.

DATES: Effective February 7, 2009, through February 6, 2010.

SUPPLEMENTARY INFORMATION:

Background

Section 101(a)(5)(A) of the MMPA (16 U.S.C. 1361 et seq.) directs the National Marine Fisheries Service (NMFS) 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. Under the MMPA, the term "taking" means to harass, hunt, capture, or kill or to attempt to harass, hunt, capture, or kill marine mammals.

Authorization may be granted for periods up to 5 years if NMFS finds, after notification and opportunity for public comment, that the taking will have a negligible impact on the species or stock(s) of marine mammals 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 for monitoring and reporting of such taking.

Regulations governing the taking of Pacific harbor seals (Phoca vitulina richardsi), northern elephant seals (Mirounga angustirostris), California sea lions (Zalophus californianus), and northern fur seals (Callorhinus ursinus), by harassment, incidental to missile and rocket launches, aircraft flight test operations, and helicopter operations at VAFB, were issued on February 6, 2009 (74 FR 6236), and remain in effect until February 6, 2014. For detailed information on this action, please refer to that document. These regulations include mitigation, monitoring, and reporting requirements for the incidental take of marine mammals during missile and rocket launches at VAFB.

This LOA is effective from February 7, 2009, through February 6, 2010, and authorizes the incidental take of the four marine mammal species listed above that may result from the launching of up to 30 space and missile vehicles and up to 20 rockets annually from VAFB, as well as from aircraft and helicopter operations. Harbor seals haul-out on several sites on VAFB, and harbor seals, California sea lions, elephant seals, and northern fur seals are found on various haul-out sites and rookeries on San Miguel Island. Currently, six space launch vehicle programs use VAFB to launch satellites into polar orbit: Delta II, Taurus, Atlas V, Delta IV, Falcon, and Minotaur. Also a variety of small missiles, several types of interceptor and target vehicles, and fixed-wing aircrafts are launched from VAFB.

The activities under these regulations create two types of noise: continuous (but short-duration) noise, due mostly to combustion effects of aircraft and launch vehicles, and impulsive noise, due to sonic boom effects. Launch operations are the major source of noise on the marine environment from VAFB. The operation of launch vehicle engines produces significant sound levels. The noise generated by VAFB activities will result in the incidental harassment of pinnipeds, both behaviorally and in terms of physiological (auditory) impacts. The noise and visual disturbances from space launch vehicle and missile launches and aircraft and helicopter operations may cause the animals to move towards or enter the water. Take of pinnipeds will be minimized through implementation of the following mitigation measures: (1) all aircraft and helicopter flight paths must maintain a minimum distance of 1,000 ft (305 m) from recognized seal haul-outs and rookeries; (2) missile and rocket launches must, whenever possible, not be conducted during the harbor seal pupping season of March through June; (3) VAFB must avoid, whenever possible, launches which are predicted to produce a sonic boom on the Northern Channel Islands during the primary pinniped pupping seasons of March through June; and (4) monitoring methods will be reviewed by NMFS if post-launch surveys determine that an injurious or lethal take of a marine mammal occurred. VAFB will also use monitoring surveys, audio-recording equipment, and time-lapse video to monitor the animals before, during, and after rocket launches, and to measure sound levels generated by the launches. Reports will be submitted to NMFS after each LOA expires, and a final comprehensive report, which will summarize all previous reports and assess cumulative impacts, will be submitted before the rule expires. This LOA will be renewed annually based on review of the annual monitoring report.
