Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et seq.) direct 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 specified activity (other than commercial fishing) within a specified geographical region if certain findings are made and either regulations are issued or, if the taking is limited to harassment, a notice of a proposed authorization is provided to the public for review.
Permission may be granted 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 subsistence uses and that the permissible methods of taking and requirements pertaining to the monitoring and reporting of such takings are set forth. NMFS has defined “negligible impact” in 50 CFR 216.103 as “...an impact resulting from the specified activity that cannot be reasonably expected to, and is not reasonably likely to, adversely affect the species or stock through effects on annual rates of recruitment or survival.”
Subsection 101(a)(5)(D) of the MMPA established an expedited process by which citizens of the United States can apply for an authorization to incidentally take small numbers of marine mammals by harassment. Under Section 3(18)(A), the MMPA defines “harassment” as:
...any act of pursuit, torment, or annoyance which (i) has the potential to injure a marine mammal or marine mammal stock in the wild; or (ii) has the potential to disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns, including, but not limited to, migration, breathing, nursing, breeding, feeding, or sheltering.
The term “Level A harassment” means harassment described in subparagraph (A)(i). The term “Level B harassment” means harassment described in subparagraph (A)(ii).
Subsection 101(a)(5)(D) establishes a 45-day time limit for NMFS review of an application followed by a 30-day public notice and comment period on any proposed authorizations for the incidental harassment of small numbers of marine mammals. Within 45 days of the close of the comment period, NMFS must either issue or deny issuance of the authorization.
Summary of Request
On January 9, 2003, NMFS received a letter from Glenn R. VanBlaricom, Ph.D., Washington Cooperative Fish and Wildlife Research Unit, requesting an IHA for the possible harassment of small numbers of California sea lions (Zalophus californianus), Pacific harbor seals (Phoca vitulina), and northern elephant seals (Mirounga angustirostris) incidental to research surveys performed for the purpose of assessing trends over time in black abalone populations at permanent study sites. Population trend data for black abalone populations are important and needed for several reasons. First, the reintroduction of sea otters to SNI since 1987 raises the possibility of conflict between sea otter conservation and abalone populations because abalones are often significant prey for sea otters. Second, the appearance of a novel exotic disease, abalone withering syndrome, at SNI in 1992, has resulted in dramatically increased rates of abalone mortality at the island. Third, California populations of black abalones have been recently designated as a candidate species for listing pursuant to the Endangered Species Act of 1973 (ESA) (as amended). The concern is that the combined effects of sea otter predation and abalone withering syndrome, following several decades during which black abalones may have been over-harvested in commercial and recreational fisheries, may cause reduction of black abalone populations to the point where risk of extinction increases. Long-term abalone population trend data from SNI is needed to determine if drastic population declines continue, and if extinction risk becomes high.
Additional information of the work proposed is contained in the application, which is available upon request (see ADDRESSES).
Comments and Responses
On June 25, 2003 (68 FR 37799) NMFS published a notice of receipt of application, with a 30-day comment period. That notice described the activity and anticipated effects on marine mammals. That information is not repeated here. During the 30-day comment period, comments were received from the Marine Mammal Commission (Commission).
Comment 1: The Commission concurs with NMFS' preliminary determination that, given the mitigation measures proposed by the applicant, the short-term impact of the subject research will result in no more than the temporary modification of behavior by California sea lions, Pacific harbor seals, and northern elephant seals. It is not clear, however, based on the information in NMFS' Federal Register notice and the application, whether sea otters could be disturbed by the proposed research, and, if so, whether a separate authorization is being sought from the Fish and Wildlife Service to cover such taking.
Response: Sea otters are not expected ashore during the time periods when the research activities would be conducted. If sea otters are sighted ashore during the abalone research, then the IHA holder (Dr. VanBlaricom) would follow similar procedures in place for other listed marine mammals. As a result of this requirement in the IHA, NMFS determines that the activity will not affect California sea otters.
Comment 2: The Commission believes that NMFS' preliminary determinations are reasonable, provided NMFS is satisfied that the proposed monitoring program is sufficient to detect the effects of the proposed research activities, including any mortality and/or serious injury that results from startle responses, or stampedes. NMFS' Federal Register notice states that no takings by injury and/or death are anticipated as a result of the proposed activities. The Commission notes, however, that while the proposed mitigation measures are expected to reduce the possibility of injury or death of animals, the potential for such taking remains. Consequently, the Commission recommends that any authorization issued to the applicant specify that, if a mortality or serious injury of a marine mammal occurs which appears to be related to the abalone research, further research activities be suspended while NMFS determines whether steps can be taken to avoid further injuries or mortalities or until such taking can be authorized by regulations promulgated under section 101(a)(5)(A) of the MMPA.
Response: In almost all cases, shoreline habitats near the abalone study sites are gently sloping sandy beaches or horizontal sandstone platforms with unimpeded and non-hazardous access to the water. If disturbed, hauled animals may move toward the water without risk of encountering significant hazards. In these circumstances, the risk of serious injury or death to hauled animals is very low.
One exception to the low risk of marine mammal injury or mortality associated with abalone research would be if disturbances occur during breeding season, as it is possible that mothers and dependent pups may become separated. If separated pairs don't reunite fairly quickly, risks of mortality to pups may Start Printed Page 57429increase. Also, adult northern elephant seals may trample elephant seal pups if disturbed. Trampling increases the risk of injury or death to the pups.
NMFS concurs that all research activities be suspended, and that NMFS immediately be notified, in the case that mortality or serious injury to a marine mammal occurs which appears to be related to the abalone research. The following required mitigation measures will both reduce the possibility of incidental harassment takes and lower the possibility of serious injury or mortality.
Researchers will be judicious in the route of approach to abalone study sites, avoiding close contact with pinnipeds hauled out on shore. In no case will marine mammals be deliberately approached by abalone researchers, and in all cases every possible measure will be taken to select a pathway of approach to study sites that minimizes the number of marine mammals harassed. Each visit to a given study site will last for a maximum of 4 hours, after which the site is vacated and can be reoccupied by any hauled marine mammals that were disturbed by the presence of abalone researchers. NMFS will be notified immediately and all research activities will be suspended in the case that mortality or serious injury to a marine mammal occurs which appears to be related to the abalone research.
Researchers will avoid visiting those black abalone study sites with resident pinnipeds during periods of breeding and lactation from February through October. During these periods of time, abalone research activities will be confined to black abalone sites where pinniped breeding and post-partum nursing does not occur.
Researchers will limit visits to site 8 to the period from November through January, and suspend research activities and immediately vacate any areas upon which Guadalupe fur seals are hauled out or that California sea otters are occupying.
Dr. Glenn VanBlaricom and associates will conduct marine mammal monitoring during abalone surveys in order to verify that the taking of marine mammals, by harassment, incidental to abalone research surveys, will have a negligible impact on marine mammal stocks and to ensure that these harassment takings are at the lowest level practicable.
Currently, all biological research activities at SNI are subject to approval and regulation by the Environmental Planning and Management Department (EPMD), US Navy. The US Navy owns SNI and closely regulates all civilian access to and activity on the island, including biological research. Therefore, monitoring activities will be closely coordinated with Navy marine mammal biologists located on SNI.
In addition, status and trends of pinniped aggregations at SNI are monitored by the NMFS Southwest Fisheries Science Center. Also, ongoing long-term studies of pinniped population dynamics, migratory and foraging behavior, and foraging ecology at SNI are conducted by staff at Hubbs-Sea World Research Institute (HSWRI).
Monitoring requirements in relation to Dr. VanBlaricom's abalone research surveys will include observations made by the applicant and his associates. Observations of unusual behaviors, numbers, or distributions of pinnipeds on SNI will be reported to EPMD, NMFS, and HSWRI so that any potential follow-up observations can be conducted by the appropriate personnel. In addition, observations of tag-bearing pinniped carcasses as well as any rare or unusual species of marine mammals will be reported to EPMD, allowing transmittal of this information to appropriate agencies and personnel.
A draft final report must be submitted to the Regional Administrator, and the Director, Office of Protected Resources, NMFS, within 60 days after the conclusion of the year-long field season. A final report must be submitted to the Regional Administrator and the Director, Office of Protected Resources, NMFS, within 30 days after receiving comments from NMFS on the draft final report. If no comments are received from NMFS, the draft final report will be considered to be the final report.
Endangered Species Act (ESA)
NMFS has determined that the abalone research activities and the accompanying IHA will not have an effect on species listed under the ESA. Therefore, consultation under Section 7 was not required.
National Environmental Policy Act
In accordance with the NOAA Administrative Order 216-6 (Environmental Review Procedures for Implementing the National Environmental Policy Act, May 20, 1999), NMFS has determined, based on a programmatic NEPA assessment conducted on the impact of NMFS' rulemaking for the issuance of IHAs (61 FR 15884; April 10, 1996) and the content and analysis of Dr. VanBlaricom's request for an IHA, that the proposed issuance of this IHA to Dr. VanBlaricom by NMFS will not individually or cumulatively result in a significant impact on the quality of the human environment as defined in 40 CFR 1508.27. Therefore, the action of issuing an IHA for these activities meets the definition of a “Categorical Exclusion” and is exempted from further environmental review.
NMFS has determined that the impact of abalone research, as described in this document, in the earlier Federal Register notice published on June 25, 2003 (68 FR 37799), and in the application for an IHA, should result, at worst, in the temporary modification in behavior by California sea lions, Pacific harbor seals and northern elephant seals. The effects of abalone research surveys on SNI are expected to be limited to short term and localized changes in behavior involving relatively small numbers of pinnipeds. While behavioral modifications, including temporarily vacating onshore haulouts, may be made by these species to avoid the presence and nearness of abalone researchers, this action is expected to have a negligible impact on the animals. In addition, no take by injury and/or death is anticipated, and harassment takes will be at the lowest level practicable due to incorporation of mitigation measures.
NMFS has issued an IHA to Dr. Glenn R. VanBlaricom to take small numbers of Pacific harbor seals, California sea lions and Northern elephant seals for a 1-year period incidental to abalone population trend research, provided the previously mentioned mitigation, monitoring, and reporting requirements described in this document are undertaken.Start Signature
