SUPPLEMENTARY INFORMATION:

Section 101(a)(5)(A) of the MMPA (16 U.S.C. 1361 et seq.) directs NMFS to allow, on 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.

Permission 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 pertaining to the monitoring and reporting of such taking. Regulations governing the taking of seals and sea lions incidental to missile and rocket launches, aircraft flight test operations, and helicopter operations at Vandenberg Air Force Base, CA (Vandenberg AFB) were published on March 1, 1999 (64 FR 9925), and remain in effect until December 31, 2003.

Summary of Request

In accordance with the MMPA, as amended, and implementing regulations, a 1-year LOA to take small numbers of seals and sea lions was issued on May 31, 2002, to the 30th Space Wing (67 FR 38939, June 6, 2002). On August 22, 2002, the 30th Space Wing, U.S. Air Force at Vandenberg AFB, requested an amendment to this LOA to include launches of the Ground-Based Interceptor (GBI) and Alternative Boost Vehicle (ABV).

The Missile Defense Agency is developing the Ground-Based Midcourse Defense (GMD) Element of the conceptual Ballistic Missile Defense Start Printed Page 25348System (BMDS). The GMD Element is designed to protect the United States in the event of a limited ballistic missile attack by destroying the threat missile in mid-course phase of its flight. The GBI canisterized booster and uncanisterized ABV that make up part of the GMD Element, will be flight-tested from Launch Facility (LF)-21 and 23 on the northern end of north Vandenberg AFB. Previously, pinnipeds rarely used this area, but during recent marine mammal surveys conducted in March and April, 2002 and with the overall increase in the harbor seal populations at Vandenberg AFB, a new harbor seal haul-out site was discovered that is regularly used by harbor seal mothers and their pups. This site, designated as Lions Head, is approximately 2.0 km (1 mi) from LF-21 and LF-23; therefore, the 30th Space Wing, Vandenberg AFB, has requested that the GBI boost vehicle launches be included under the 10 ICBM launches authorized for taking pinipeds incidental to launches at Vandenberg AFB under the regulations (64 FR 9925, March 1, 1999).

In 1999, the potential environmental impacts of the activities associated with two canisterized GBI booster verification test flights from LF-21 in northern Vandenberg AFB were analyzed in the 1999 Booster Verification Test Environmental Assessment (EA). The 1999 EA analyzed the potential environmental impacts of all pre-flight, launch, and post-launch activities. Congressional direction in the Defense Authorization Act for fiscal year 2001 included the development of a backup or alternative booster option involving proven technologies. A decision was made to develop and test a second boost vehicle, the uncanisterized ABV. The proposed ABV test flights are an important step in the development of the GMD Element. The ABV being proposed for launch from LF-23 would consist of the GMD Element. The ABV being proposed for launch from LF-23 would consist of a commercially available, solid propellant booster consisting of three stages and an exo-atmospheric kill vehicle emulator that may contain a divert and attitude control system

.

Impacts on Marine Mammals

A detailed description of the pinniped stocks potentially affected by missile and rocket launches from Vandenberg AFB and an assessment of those impacts can be found in the final rule on the taking of marine mammals incidental to these activities (64 FR 9925, March 1, 1999).

The primary potential for impacts to pinnipeds would be from the noise created during the proposed missile launches. Noise from Minuteman launches, which have been previously launched from LF-21 and LF-23, ranges from 98 dBA approximately 4.2 km (2.6 mi) from the launch site to 80 dBA approximately 13 km (8 mi) from the launch site. The level of noise for the ABV during launch and flight is expected to be less and relatively short in duration. At approximately the same distance from LF-21, the previous BVT-2 launch (GBI canisterized vehicle) was 6 dB less than the Minuteman III launch and 17 dB less than Peacekeeper launches. Pacific harbor seals (Phoca vitulina), the main pinniped species using north Vandenberg AFB, would normally be at least 2.0 km (1 mi) from the launch site. Other pinnipeds, such as California sea lions (Zalophus californianus) and northern elephant seals (Mirounga angustirostris), may haul-out temporarily on beaches several kilometers from the launch facilities. Noise from prior launches has not appeared to affect pinniped use of the coastal areas on Vandenberg AFB. Pinniped monitoring has been performed for launches of larger missiles on north Vandenberg AFB, such as the Peacekeeper and Delta II. The effect on harbor seals, which were most susceptible to disturbance, has been limited to a negligible short-term (5-30 min) abandonment of nearby haul-out areas. No pinniped mother-pup separations have been noted at the harbor seal haul-out sites closest to launch site. Recent surveys discovered a new harbor seal haul-out site on north Vandenberg AFB that is regularly used by up to 3 harbor seal mothers and their pups. The 30th Space Wing began monitoring harbor seals at this site for ICBM (Minuteman and Peacekeeper) launches that occurred during the harbor seal pupping season (March-June) in accordance with the small take regulations and LOA.

The GBI canisterized and uncanisterized booster launches would be included in the 10 ICBM launches per year that are currently allowed under the regulations and LOA. The planned 6 GBI launches over the next five years will not cause the number of ICBM launches to go over the authorized 10/year.

Monitoring and Reporting

In accordance with the regulations (64 FR 9925, March 1, 1999) and LOA, acoustic monitoring will be performed during initial launch of each type of vehicle (this would be accomplished for the initial GBI canisterized booster launch) and harbor seal monitoring would be conducted during the pupping season in accordance with Vandenberg AFB guidelines. The intermittent launches planned for the ABV test flights (6 flights over the next 5 years) and the relatively small size (smaller than Minuteman and Peacekeeper missiles) are not expected to have more than a negligible impact on harbor seals at Vandenberg AFB.

National Environmental Policy Act (NEPA)

Under rulemaking conducted in 1999 (64 FR 9925, March 1, 1999), NMFS reviewed this action in accordance with NEPA and the Endangered Species Act (ESA). Please refer to that document for additional information. Because the action discussed in this document is not substantially different from the 1999 action, and because no significant new scientific information or analyses have been developed in the past several years significant enough to warrant new NEPA documentation, this action is categorically excluded from further review under NOAA Administrative Order 216-6.

ESA

This action will not affect listed marine mammal species as these species are not expected to haulout on north Vandenberg AFB and thereby potentially be affected through harassment and fleeing from the haulout. No other species listed under the ESA will be affected by this modification.

Determinations

Because the addition of the GBI and ABV missiles to the launch list at Vandenberg AFB will not result in an increase in the number of missile launches authorized to take pinnipeds by Level B harassment under the LOA, NMFS does not expect additional impacts, individually or cumulatively, to occur and therefore, NMFS has determined that the incidental harassment will remain small and not have more than a negligible impact on the pinniped populations off the Vandenberg AFB coast.
