SUPPLEMENTARY INFORMATION:
Background
Section 101(a)(5)(D) of the Marine Mammal Protection Act of 1972,
as amended (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 of a species or population
stock, by U.S. citizens who engage in a specified activity (other than
commercial fishing) within a specified geographical region if, after
NMFS provides a notice of a proposed authorization to the public for
review and comment: (1) NMFS makes certain findings; and (2) the taking
is limited to harassment.
An Authorization shall be granted for the incidental taking of
small numbers of marine mammals 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 (where relevant). The Authorization must
also set forth the permissible methods of taking; other means of
effecting the least practicable adverse impact on the species or stock
and its habitat; and requirements pertaining to the mitigation,
monitoring and reporting of such taking. 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.''
Except with respect to certain activities not pertinent here, 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 [Level A harassment]; 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 [Level B harassment].
Summary of Request
On April 7, 2014, NMFS received an application from Glacier Bay NP
requesting that we issue an Authorization for the take of marine
mammals, incidental to conducting monitoring and research studies on
glaucus-winged gulls (Larus glaucescens) within Glacier Bay National
Park and Preserve in Alaska. NMFS determined the application complete
and adequate on May 1, 2014.
Glacier Bay NP proposes to conduct ground-based and vessel-based
surveys to collect data on the number and distribution of nesting gulls
within five study sites in Glacier Bay, AK during September, 2014.
The proposed activities are within the vicinity of pinniped haulout
sites and the following aspects of the proposed activities are likely
to result in the take of marine mammals: noise generated by motorboat
approaches and departures; noise generated by researchers while
conducting ground surveys; and human presence during the monitoring and
research activities. There are two species with confirmed occurrence in
[[Page 56066]]
the action area: harbor seals (Phoca vitulina) and Steller sea lions
(Eumetopia jubatus). Of the two species, only harbor seals would most
likely be harassed incidental to conducting the seabird monitoring and
research activities due to the researchers avoiding any site with
Steller sea lions present. Thus, by incorporation of this mitigation
measure for Steller sea lions, we anticipate that take, by Level B
harassment only, of individuals of harbor seals could result from the
specified activity.
Description of the Specified Activity
Overview
Glacier Bay NP proposes to identify the onset of gull nesting;
conduct mid-season surveys of adult gulls, and locate and document gull
nest sites within the following study areas: Boulder, Lone, and
Flapjack Islands, and Geikie Rock. Each of these study sites contains
harbor seal haulout sites and Glacier Bay NP proposes to visit each
site up to five times during the research season.
Glacier Bay NP must conduct the gull monitoring studies to meet the
requirements of a 2010 Record of Decision for a Legislative
Environmental Impact Statement (NPS 2010) which states that Glacier Bay
NP must initiate a monitoring program for the gulls to inform future
native egg harvests by the Hoonah Tlingit in Glacier Bay, AK. Glacier
Bay NP actively monitors harbor seals at breeding and molting sites to
assess population trends over time (e.g., Mathews & Pendleton, 2006;
Womble et al., 2010). Glacier Bay NP also coordinates pinniped
monitoring programs with National Marine Mammal Laboratory and the
Alaska Department of Fish & Game and plans to continue these
collaborations and sharing of monitoring data and observations in the
future.
Dates and Duration
The Authorization would be effective from September 1, 2014 through
September 30, 2014. Following is a brief summary of the activities.
Glacier Bay NP proposes to conduct a maximum of three ground-based
surveys per each study site and a maximum of two vessel-based surveys
per each study site.
Specified Geographic Region
The proposed study sites would occur in the vicinity of the
following locations: Boulder (58[deg]33'18.08'' N; 136[deg]1'13.36''
W), Lone (58[deg]43'17.67'' N; 136[deg]17'41.32'' W), and Flapjack
(58[deg]35'10.19'' N; 135[deg]58'50.78'' W) Islands, and Geikie Rock
(58[deg]41'39.75'' N; 136[deg]18'39.06'' W) in Glacier Bay, Alaska.
Glacier Bay NP will also conduct studies at Tlingit Point Islet located
at 58[deg]45'16.86'' N; 136[deg]10'41.74'' W; however, there are no
reported pinniped haulout sites at that location.
Detailed Description of Activities
Glacier Bay NP proposes to conduct: (1) Ground-based surveys at a
maximum frequency of three visits per site; and (2) vessel-based
surveys at a maximum frequency of two visits per site.
Ground-Based Surveys: These surveys involve two trained observers
visiting the largest gull colony on each island to: (1) Obtain
information on the numbers of nests, their location, and contents
(i.e., eggs or chicks); (2) determine the onset of laying,
distribution, abundance, and predation of gull nests and eggs; and (3)
record the proximity of other species relative to colony locations.
The observers would access each island using a kayak, a 32.8 to
39.4-foot (ft) (10 to 12 meter (m)) motorboat, or a 12 ft (4 m)
inflatable rowing dinghy. The landing craft's transit speed would not
exceed 4 knots (4.6 miles per hour (mph). Ground surveys generally last
from 30 minutes to up to two hours depending on the size of the island
and the number of nesting gulls. Glacier Bay NP will discontinue ground
surveys after they detect the first hatchling to minimize disturbance
to the gull colonies.
Vessel-Based Surveys: These surveys involve two trained observers
observing and counting the number of adult and fledgling gulls from the
deck of a motorized vessel which would transit around each island at a
distance of approximately 328 ft (100 m) to avoid flushing the birds
from the colonies. Vessel-based surveys generally last from 30 minutes
to up to two hours depending on the size of the island and the number
of nesting gulls.
Comments and Responses
We published a notice of receipt of Glacier Bay NP's application
and proposed Authorization in the Federal Register on June 4, 2014 (79
FR 32226). During the 30-day comment period, we received one comment
from the Marine Mammal Commission (Commission) which recommended that
we issue the requested Authorization, provided that Glacier Bay NP
carries out the required monitoring and mitigation measures as
described in the notice of the proposed authorization (79 FR 32226,
June 4, 2014) and the application. We have included all measures
proposed in the notice of the proposed authorization (79 FR 32226, June
4, 2014) in the final Authorization.
We also received comments from one private citizen who opposed the
authorization on the basis that NMFS should not allow any
Authorizations for harassment. We considered the commenter's general
opposition to Glacier Bay NP's activities and to our issuance of an
Authorization. The Authorization, described in detail in the Federal
Register notice of the proposed Authorization (79 FR 32226, June 4,
2014) includes mitigation and monitoring measures to effect the least
practicable impact to marine mammals and their habitat. It is our
responsibility to determine whether the activities will have a
negligible impact on the affected species or stocks; will have an
unmitigable adverse impact on the availability of the species or
stock(s) for subsistence uses, where relevant; and to prescribe the
means of effecting the least practicable adverse impact on the affected
species or stocks and their habitat, as well as monitoring and
reporting requirements.
Regarding the commenter's opposition to authorizing harassment, the
MMPA allows U.S. citizens (which includes Glacier Bay NP) to request
take of marine mammals incidental to specified activities, and requires
us to authorize such taking if we can make the necessary findings
required by law and if we set forth the appropriate prescriptions. As
explained throughout the Federal Register notice (79 FR 32226, June 4,
2014), we made the necessary preliminary findings under 16 U.S.C.
1371(a)(5)(D) to support issuance of Authorization.
Description of Marine Mammals in the Area of the Specified Activity
The marine mammals most likely to be harassed incidental to
conducting seabird monitoring and research are Pacific harbor seals. We
do not anticipate harassment of Steller sea lions due to the
researchers avoiding any site with Steller sea lions present.
We refer the reader to Allen and Angliss (2013) for general
information on these species which we presented in the notice of
proposed authorization (79 FR 32226, June 4, 2014). The 2013 NMFS
Marine Mammal Stock Assessment Report is available at: http://www.nmfs.noaa.gov/pr/sars/pdf/ak2013_final.pdf.
Other Marine Mammals in the Proposed Action Area
Northern sea otters (Enhydra lutris kenyoni) and polar bears (Ursis
maritimus) listed as threatened under the Endangered Species Act could
occur in the proposed area. The U.S. Fish and Wildlife Service manages
these species
[[Page 56067]]
and we do not consider them further in this notice of issuance of an
Authorization.
Potential Effects of the Specified Activities on Marine Mammals
Acoustic and visual stimuli generated by: (1) Noise generated by
kayak, motorboat, or dinghy approaches and departures; (2) human
presence during seabird monitoring and research activities, have the
potential to cause Pacific harbor seals hauled out on Boulder, Lone,
and Flapjack Islands, and Geikie Rock to flush into the surrounding
water or to cause a short-term behavioral disturbance for marine
mammals.
We expect that acoustic and visual stimuli resulting from the
proposed activities has the potential to harass marine mammals. We also
expect that these disturbances would be temporary and result, at worst,
in a temporary modification in behavior and/or low-level physiological
effects (Level B harassment) of harbor seals.
We included a summary and discussion of the ways that the types of
stressors associated with Glacier Bay NP's specified activities (i.e.,
visual and acoustic disturbance) have the potential to impact marine
mammals in the notice of proposed authorization (79 FR 32226, June 4,
2014).
Vessel Strike: The potential for striking marine mammals is a
concern with vessel traffic. However, it is highly unlikely that the
use of small, slow-moving kayaks or boats to access the research areas
would result in injury, serious injury, or mortality to any marine
mammal. Typically, the reasons for vessel strikes are fast transit
speeds, lack of maneuverability, or not seeing the animal because the
boat is so large. Glacier Bay NP's researchers will access areas at
slow transit speeds in easily maneuverable kayaks or small boats
negating any chance of an accidental strike.
Rookeries: No monitoring or research activities would occur on
pinniped rookeries and breeding animals are concentrated in areas where
researchers would not visit. Therefore, we do not expect mother and pup
separation or crushing of pups during flushing.
Anticipated Effects on Marine Mammal Habitat
We considered these impacts in detail in the notice for the
proposed authorization (79 FR 32226, June 4, 2014). Briefly, we do not
anticipate that the proposed research activities would result in any
significant or long-term effects on the habitats used by the marine
mammals in the proposed area, including the food sources they use
(i.e., fish and invertebrates). While we anticipate that the specified
activity could potentially result in marine mammals avoiding certain
areas due to temporary ensonification and human presence, this impact
to habitat is temporary and reversible. We do not consider behavioral
modification to cause significant or long-term consequences for
individual marine mammals or their populations.
Mitigation
In order to issue an incidental take authorization under section
101(a)(5)(D) of the MMPA, NMFS must set forth the permissible methods
of taking pursuant to such activity, and other means of effecting the
least practicable adverse impact on such species or stock and its
habitat, paying particular attention to rookeries, mating grounds, and
areas of similar significance, and on the availability of such species
or stock for taking for certain subsistence uses (where relevant).
The Glacier Bay NP has reviewed the following source documents and
has incorporated a suite of proposed mitigation measures into their
project description.
(1) Recommended best practices in Womble et al. (2013); Richardson
et al. (1995); Pierson et al. (1998); and Weir and Dolman, (2007).
To reduce the potential for disturbance from acoustic and visual
stimuli associated with the activities Glacier Bay NP and/or its
designees has proposed to implement the following mitigation measures
for marine mammals:
Perform pre-survey monitoring before deciding to access a
study site;
Avoid accessing a site based on a pre-determined threshold
of animals present; sites used by pinnipeds for pupping; or sites used
by Steller sea lions;
Perform controlled and slow ingress to the study site to
prevent a stampede and select a pathway of approach to minimize the
number of marine mammals harassed;
Monitor for offshore predators. Avoid approaching the
study site if killer whales (Orcinas orca) are present. If Glacier Bay
and/or its designees see predators in the area, they must not disturb
the animals until the area is free of predators.
Maintain a quiet research atmosphere in the visual
presence of pinnipeds.
Pre-Survey Monitoring: Prior to deciding to land onshore to conduct
the study, the researchers would use high-powered image stabilizing
binoculars from the watercraft to document the number, species, and
location of hauled out marine mammals at each island. The vessels would
maintain a distance of 328 to 1,640 ft (100 to 500 m) from the
shoreline to allow the researchers to conduct pre-survey monitoring.
Site Avoidance: Researchers would decide whether or not to approach
the island based on the species present, number of individuals, and the
presence of pups. If there are high numbers (greater than 25) of hauled
out harbor seals and/or young pups or there are any Steller sea lions
present, the researchers will not approach the island and will not
conduct gull monitoring research.
Controlled Landings: The researchers would determine whether to
approach the island based on the number and type of animals present. If
the island has fewer than 25 individuals without pups, he/she would
approach the island by motorboat at a speed of approximately 2 to 3
knots (2.3 to 3.4 mph). This would provide enough time for any marine
mammals present to slowly enter the water without panic or stampede.
The researchers would also select a pathway of approach farthest from
the hauled out harbor seals to minimize disturbance.
Minimize Predator Interactions: If marine predators (i.e. killer
whales) are present in the vicinity of hauled out marine mammals, the
researchers would not approach the study site.
Noise Reduction Protocols: While onshore at study sites, the
researchers would remain vigilant for hauled out marine mammals. If
marine mammals are present, the researchers would move slowly and use
quiet voices to minimize disturbance to the animals present.
Mitigation Conclusions
NMFS has carefully evaluated Glacier Bay NP's proposed mitigation
measures in the context of ensuring that we prescribe the means of
effecting the least practicable impact on the affected marine mammal
species and stocks and their habitat. Our evaluation of potential
measures included consideration of the following factors in relation to
one another:
The manner in which, and the degree to which, the
successful implementation of the measure is expected to minimize
adverse impacts to marine mammals;
The proven or likely efficacy of the specific measure to
minimize adverse impacts as planned; and
The practicability of the measure for applicant
implementation.
Any mitigation measure(s) prescribed by NMFS should be able to
accomplish, have a reasonable likelihood of
[[Page 56068]]
accomplishing (based on current science), or contribute to the
accomplishment of one or more of the general goals listed here:
1. Avoidance or minimization of injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may contribute to this goal).
2. A reduction in the numbers of marine mammals (total number or
number at biologically important time or location) exposed to kayak,
motorboat, or dinghy operations or visual presence that we expect to
result in the take of marine mammals (this goal may contribute to 1,
above, or to reducing harassment takes only).
3. A reduction in the number of times (total number or number at
biologically important time or location) individuals exposed to kayak,
motorboat, or dinghy operations or visual presence that we expect to
result in the take of marine mammals (this goal may contribute to 1,
above, or to reducing harassment takes only).
4. A reduction in the intensity of exposures (either total number
or number at biologically important time or location) to kayak,
motorboat, or dinghy operations or visual presence that we expect to
result in the take of marine mammals (this goal may contribute to a,
above, or to reducing the severity of harassment takes only).
5. Avoidance or minimization of adverse effects to marine mammal
habitat, paying special attention to the food base, activities that
block or limit passage to or from biologically important areas,
permanent destruction of habitat, or temporary destruction/disturbance
of habitat during a biologically important time.
6. For monitoring directly related to mitigation--an increase in
the probability of detecting marine mammals, thus allowing for more
effective implementation of the mitigation.
Based on the evaluation of Glacier Bay NP's proposed measures, NMFS
has determined that the proposed mitigation measures provide the means
of effecting the least practicable impact on marine mammal species or
stocks and their habitat, paying particular attention to rookeries,
mating grounds, and areas of similar significance.
Monitoring
In order to issue an ITA for an activity, section 101(a)(5)(D) of
the MMPA states that NMFS must set forth ``requirements pertaining to
the monitoring and reporting of such taking.'' The MMPA implementing
regulations at 50 CFR 216.104(a)(13) indicate that requests for
Authorizations must include the suggested means of accomplishing the
necessary monitoring and reporting that will result in increased
knowledge of the species and of the level of taking or impacts on
populations of marine mammals that we expect to be present in the
proposed action area.
Glacier Bay NP submitted a marine mammal monitoring plan in section
13 of their Authorization application. NMFS or the Glacier Bay NP has
not modified or supplemented the plan based on comments or new
information received from the public during the public comment period.
Monitoring measures prescribed by NMFS should accomplish one or
more of the following general goals:
1. An increase in the probability of detecting marine mammals in
order to generate more data to contribute to the analyses mentioned
later;
2. An increase in our understanding of how many marine mammals
would be affected by the research activities and the likelihood of
associating those exposures with specific adverse effects, such as
behavioral harassment, temporary or permanent threshold shift;
3. An increase in our understanding of how marine mammals respond
to acoustic and visual stimuli that we expect to result in take and how
those anticipated adverse effects on individuals (in different ways and
to varying degrees) may impact the population, species, or stock
(specifically through effects on annual rates of recruitment or
survival) through any of the following methods:
a. Behavioral observations in the presence of stimuli compared to
observations in the absence of stimuli (i.e., we need to be able to
accurately predict received level, distance from source, and other
pertinent information);
b. Physiological measurements in the presence of stimuli compared
to observations in the absence of stimuli (i.e., we need to be able to
accurately predict received level, distance from source, and other
pertinent information);
c. Distribution and/or abundance comparisons in times or areas with
concentrated stimuli versus times or areas without stimuli;
4. An increased knowledge of the affected species; and
5. An increase in our understanding of the effectiveness of certain
mitigation and monitoring measures.
As part of its Authorization application, Glacier Bay NP proposes
to sponsor marine mammal monitoring during the present project, in
order to implement the mitigation measures that require real-time
monitoring, and to satisfy the monitoring requirements of the
Authorization.
The Glacier Bay NP researchers will monitor the area for pinnipeds
during all research activities. Monitoring activities will consist of
conducting and recording observations on pinnipeds within the vicinity
of the proposed research areas. The monitoring notes would provide
dates and location of the researcher's activities and the number and
type of species present. The researchers would document the behavioral
state of animals present, and any apparent disturbance reactions or
lack thereof.
Reporting
Glacier Bay NP will submit a final monitoring report to us no later
than 90 days after the expiration of the Incidental Harassment
Authorization, if we issue it. The final report will describe the
operations conducted and sightings of marine mammals near the proposed
project. The report will provide full documentation of methods,
results, and interpretation pertaining to all monitoring. The final
report will provide:
1. A summary and table of the dates, times, and weather during all
research activities.
2. Species, number, location, and behavior of any marine mammals
observed throughout all monitoring activities.
3. An estimate of the number (by species) of marine mammals exposed
to acoustic or visual stimuli associated with the research activities.
4. A description of the implementation and effectiveness of the
monitoring and mitigation measures of the Authorization and full
documentation of methods, results, and interpretation pertaining to all
monitoring.
In the unanticipated event that the specified activity clearly
causes the take of a marine mammal in a manner prohibited by the
authorization, such as an injury (Level A harassment), serious injury,
or mortality (e.g., vessel-strike, stampede, etc.), Glacier Bay NP
shall immediately cease the specified activities and immediately report
the incident to the Chief, Permits and Conservation Division, Office of
Protected Resources, NMFS, at 301-427-8401 and/or by email to
[email protected] and [email protected] and the Alaska Regional
Stranding Coordinator at (907) 586-7248 ([email protected]). The
report must include the following information:
[[Page 56069]]
Time, date, and location (latitude/longitude) of the
incident;
Description and location of the incident (including water
depth, if applicable);
Environmental conditions (e.g., wind speed and direction,
Beaufort sea state, cloud cover, and visibility);
Description of all marine mammal observations in the 24
hours preceding the incident;
Species identification or description of the animal(s)
involved;
Fate of the animal(s); and
Photographs or video footage of the animal(s) (if
equipment is available).
Glacier Bay NP shall not resume its activities until NMFS is able
to review the circumstances of the prohibited take. We will work with
Glacier Bay to determine what is necessary to minimize the likelihood
of further prohibited take and ensure MMPA compliance. Glacier Bay NP
may not resume their activities until notified by us via letter, email,
or telephone.
In the event that Glacier Bay NP discovers an injured or dead
marine mammal, and the lead researcher determines that the cause of the
injury or death is unknown and the death is relatively recent (i.e., in
less than a moderate state of decomposition as we describe in the next
paragraph), Glacier Bay NP will immediately report the incident to the
Chief, Permits and Conservation Division, Office of Protected
Resources, NMFS, at 301-427-8401 and/or by email to
[email protected] and [email protected] and the Alaska Regional
Stranding Coordinator at (907) 586-7248 ([email protected]). The
report must include the same information identified in the paragraph
above this section. Activities may continue while we review the
circumstances of the incident. We will work with Glacier Bay NP to
determine whether modifications in the activities are appropriate.
Activities may continue while we review the circumstances of the
incident.
In the event that Glacier Bay NP discovers an injured or dead
marine mammal, and the lead visual observer determines that the injury
or death is not associated with or related to the authorized activities
(e.g., previously wounded animal, carcass with moderate to advanced
decomposition, or scavenger damage), Glacier Bay will report the
incident to the Incidental Take Program Supervisor, Permits and
Conservation Division, Office of Protected Resources, NMFS, at 301-427-
8401 and/or by email to [email protected] and [email protected]
and the Alaska Regional Stranding Coordinator at (907) 586-7248
([email protected]) within 24 hours of the discovery. Glacier Bay
NP researchers will provide photographs or video footage (if available)
or other documentation of the stranded animal sighting to us. Glacier
Bay NP can continue their research activities. Activities may continue
while we review the circumstances of the incident.
Estimated Take by Incidental Harassment
Except with respect to certain activities not pertinent here, 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 [Level A harassment]; 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 [Level B harassment].
Acoustic (i.e., increased sound) and visual stimuli from the
proposed research activities may have the potential to result in the
behavioral disturbance of some marine mammals. Thus, NMFS proposes to
authorize take by Level B harassment only for the proposed seabird
monitoring and research activities on Boulder, Lone, and Flapjack
Islands, and Geikie Rock, Alaska.
Based on pinniped survey counts conducted by Glacier Bay NP (e.g.,
Mathews & Pendleton, 2006; Womble et al., 2010), NMFS estimates that
the research activities could potentially affect by Level B behavioral
harassment 400 harbor seals over the course of the Authorization (Table
3). This estimate represents 12.6 percent of the Glacier Bay/Icy Strait
stock of harbor seals and accounts for a maximum disturbance of 20
harbor seals each per visit at Boulder, Lone, and Flapjack Islands, and
Geikie Rock, Alaska over a maximum level of five visits.
There is no evidence that Glacier Bay NP's planned activities could
result in injury, serious injury, or mortality within the action area.
Moreover, the required mitigation and monitoring measures would
minimize further any potential risk for injury, serious injury, or
mortality. Thus, we do not propose to authorize any injury, serious
injury, or mortality. We expect all potential takes to fall under the
category of Level B harassment only.
Encouraging and Coordinating Research
Glacier Bay NP actively monitors harbor seals at breeding and
molting haul out locations to assess trends over time (e.g., Mathews &
Pendleton, 2006; Womble et al. 2010, Womble and Gende, 2013b). This
monitoring program involves collaborations with biologists from the
Alaska Department of Fish and Game, and the National Marine Mammal
Laboratory. Glacier Bay NP will continue these collaborations and
encourage continued or renewed monitoring of marine mammal species.
Additionally, they would report vessel-based counts of marine mammals,
branded, or injured animals, and all observed disturbances to the
appropriate state and federal agencies.
Analysis and Determinations
Negligible Impact
Negligible impact' is ``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'' (50 CFR 216.103). The lack of
likely adverse effects on annual rates of recruitment or survival
(i.e., population level effects) forms the basis of a negligible impact
finding. Thus, an estimate of the number of Level B harassment takes,
alone, is not enough information on which to base an impact
determination. In addition to considering estimates of the number of
marine mammals that might be ``taken'' through behavioral harassment,
NMFS must consider other factors, such as the likely nature of any
responses (their intensity, duration, etc.), the context of any
responses (critical reproductive time or location, migration, etc.), as
well as the number and nature of estimated Level A harassment takes,
and the number of estimated mortalities, effects on habitat, and the
status of the species.
In making a negligible impact determination, NMFS considers:
The number of anticipated injuries, serious injuries, or
mortalities;
The number, nature, and intensity, and duration of Level B
harassment; and
The context in which the takes occur (e.g., impacts to
areas of significance, impacts to local populations, and cumulative
impacts when taking into account successive/contemporaneous actions
when added to baseline data);
The status of stock or species of marine mammals (i.e.,
depleted, not depleted, decreasing, increasing, stable, impact relative
to the size of the population);
[[Page 56070]]
Impacts on habitat affecting rates of recruitment/
survival; and
The effectiveness of monitoring and mitigation measures to
reduce the number or severity of incidental take.
For reasons stated previously in this document and based on the
following factors, Glacier Bay NP's specified activities are not likely
to cause long-term behavioral disturbance, permanent threshold shift,
or other non-auditory injury, serious injury, or death. These reasons
include:
1. The effects of the research activities would be limited to
short-term startle responses and localized behavioral changes due to
the short and sporadic duration of the research activities. Minor and
brief responses, such as short-duration startle or alert reactions, are
not likely to constitute disruption of behavioral patterns, such as
migration, nursing, breeding, feeding, or sheltering.
2. The availability of alternate areas for pinnipeds to avoid the
resultant acoustic and visual disturbances from the research
operations. Anecdotal reports from previous Glacier Bay NP activities
have shown that the pinnipeds returned to the various sites and did not
permanently abandon haul-out sites after Glacier Bay NP conducted their
research activities.
3. The low potential for large-scale movements leading to injury,
serious injury, or mortality because the researchers would delay
ingress into the landing areas only after the pinnipeds have slowly
entered the water.
4. Glacier Bay NP limiting access to Boulder, Lone, and Flapjack
Islands, and Geikie Rock if more than 25 animals are present or if
Steller sea lions are present in the research areas.
NMFS does not anticipate that any injuries, serious injuries, or
mortalities would occur as a result of Glacier Bay's proposed
activities, and NMFS does not propose to authorize injury, serious
injury, or mortality at this time.
Due to the nature, degree, and context of Level B (behavioral)
harassment anticipated and described (see ``Potential Effects on Marine
Mammals'' section in the in the notice of proposed authorization (79 FR
32226, June 4, 2014), we do not expect the activity to impact rates of
recruitment or survival for any affected species or stock. In addition,
the research activities would not take place in areas of significance
for marine mammal feeding, resting, breeding, or calving and would not
adversely impact marine mammal habitat.
NMFS finds that Glacier Bay NP's proposed activities will have a
negligible impact on the affected species or stocks based on the
analysis contained in this notice of the likely effects of the
specified activity on marine mammals and their habitat, and taking into
consideration the implementation of the mitigation and monitoring
measures.
Small Numbers
As mentioned previously, NMFS estimates that Glacier Bay NP's
activities could potentially affect, by Level B harassment only, one
species of marine mammal under our jurisdiction. For harbor seals, this
estimate is small (12.6 percent) relative to the population size.
Based on the analysis contained in this notice of the likely
effects of the specified activity on marine mammals and their habitat,
and taking into consideration the implementation of the mitigation and
monitoring measures, NMFS finds that Glacier Bay NP's proposed
activities would take small numbers of marine mammals relative to the
populations of the affected species or stocks.
Impact on Availability of Affected Species or Stock for Taking for
Subsistence Uses
There are no relevant subsistence uses of marine mammals implicated
by this action. Glacier Bay National Park prohibits subsistence harvest
of harbor seals within the Park (Catton, 1995).
Endangered Species Act (ESA)
NMFS does not expect that Glacier Bay NP's proposed research
activities would affect any species listed under the ESA. Therefore,
NMFS has determined that a section 7 consultation under the ESA is not
required.
National Environmental Policy Act (NEPA)
To meet our NEPA requirements for the issuance of an Authorization
to Glacier Bay NP, we prepared an Environmental Assessment (EA) titled,
``Environmental Assessment for the Issuance of an Incidental Harassment
Authorization To Take Marine Mammals by Harassment Incidental to
Conducting Seabird Research in Glacier Bay Alaska.'' We provided
relevant environmental information to the public through a previous
notice for the proposed Authorization (79 FR 32226, June 4, 2014) and
considered public comments received in response prior to finalizing our
EA and deciding whether or not to issue a Finding of No Significant
Impact (FONSI).
We conclude that issuance of an Incidental Harassment Authorization
would not significantly affect the quality of the human environment and
have issued a FONSI. Our EA and FONSI for this activity are available
upon request (see ADDRESSES).
Authorization
As a result of these determinations, we have issued an Incidental
Harassment Authorization to Glacier Bay National Park for conducting
seabird research September 1 through September 30, 2014, provided they
incorporate the previously mentioned mitigation, monitoring, and
reporting requirements.
Dated: September 15, 2014.
