National Environmental Policy Act
(NEPA)
To comply with the National
Environmental Policy Act of 1969
(NEPA; 42 U.S.C. 4321 et seq.) and
NOAA Administrative Order (NAO)
216–6A, NMFS must review our
proposed action (i.e., the issuance of an
incidental take authorization) with
respect to potential impacts on the
human environment.
This action is consistent with
categories of activities identified in CE
B4 of the Companion Manual for NOAA
Administrative Order 216–6A, which do
not individually or cumulatively have
the potential for significant impacts on
the quality of the human environment
and for which we have not identified
any extraordinary circumstances that
would preclude this categorical
exclusion. Accordingly, NMFS has
preliminarily determined that the
issuance of the proposed rule and
subsequent Letters of Authorization
qualifies to be categorically excluded
from further NEPA review. We will
review all comments submitted in
response to this notice prior to
concluding our NEPA process or making
a final decision on the request.
Purpose and Need for Regulatory
Action
This proposed rule, to be issued
under the authority of the Marine
Mammal Protection Act (MMPA) (16
U.S.C. 1361 et seq.), would establish a
framework for authorizing the take of
marine mammals incidental to NPS’s
gull and climate monitoring activities
within GLBA NP and marine bird and
mammal surveys in the SWAN region.
Researchers conducting these surveys
may cause behavioral disturbance (Level
B harassment) of harbor seals and
Steller sea lions.
We received an application from NPS
requesting five-year regulations and
authorization to take harbor seals and
Steller sea lions. Take would occur by
Level B harassment incidental to
research and monitoring activities due
to behavioral disturbance of pinnipeds.
The regulations would be valid from
2019 to 2024. Please see ‘‘Background’’
below for definitions of harassment.
Legal Authority for the Proposed Action
Section 101(a)(5)(A) of the MMPA (16
U.S.C. 1371(a)(5)(A)) directs the
Secretary of Commerce to allow, upon
request, the incidental, but not
intentional taking of small numbers of
E:\FR\FM\13DEP1.SGM
13DEP1
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
marine mammals by U.S. citizens who
engage in a specified activity (other than
commercial fishing) within a specified
geographical region for up to five years
if, after notice and public comment, the
agency makes certain findings and
issues regulations that set forth
permissible methods of taking pursuant
to that activity, as well as monitoring
and reporting requirements. Section
101(a)(5)(A) of the MMPA and the
implementing regulations at 50 CFR part
216, subpart I provide the legal basis for
issuing this proposed rule containing
five-year regulations, and for any
subsequent Letters of Authorization. As
directed by this legal authority, this
proposed rule contains mitigation,
monitoring, and reporting requirements.
amozie on DSK3GDR082PROD with PROPOSALS1
Summary of Major Provisions Within
the Proposed Rule
The following provides a summary of
some of the major provisions within the
proposed rulemaking for NPS’s research
and monitoring activities in southern
Alaska. We have preliminarily
determined that NPS’s adherence to the
proposed mitigation, monitoring, and
reporting measures listed below would
achieve the least practicable adverse
impact on the affected marine
mammals. They include:
• Measures to minimize the number
and intensity of incidental takes during
monitoring activities and to minimize
the duration of disturbances.
• Measures designed to eliminate
startling reactions.
• Eliminating or altering research
activities on GLBA NP beaches when
pups are present, and setting limits on
the frequency and duration of events
during pupping season.
Background
Paragraphs 101(a)(5)(A) and (D) of the
MMPA (16 U.S.C. 1371 (a)(5)(A) and
(D)) direct the Secretary of Commerce 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 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.
An authorization for incidental
takings shall be granted if NMFS finds
that the taking will have a negligible
impact on the species or stock(s); will
not have an unmitigable adverse impact
on the availability of the species or
stock(s) for subsistence uses (where
relevant); and if the permissible
methods of taking and requirements
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
pertaining to the mitigation, 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.
NMFS has defined ‘‘unmitigable adverse
impact’’ in 50 CFR 216.103 as an impact
resulting from the specified activity:
• That is likely to reduce the
availability of the species to a level
insufficient for a harvest to meet
subsistence needs by:
Æ Causing the marine mammals to
abandon or avoid hunting areas;
Æ Directly displacing subsistence
users; or
Æ Placing physical barriers between
the marine mammals and the
subsistence hunters; and
• That cannot be sufficiently
mitigated by other measures to increase
the availability of marine mammals to
allow subsistence needs to be met.
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 February 6, 2018, we received an
adequate and complete request from
NPS for authorization to take marine
mammals incidental to gull and climate
monitoring activities in GLBA NP. On
February 22, 2018 (83 FR 7699), we
published a notice of receipt of NPS’s
application in the Federal Register,
requesting comments and information
related to the request for 30 days. We
did not receive any comments. NPS
provided a revised application
incorporating minor revisions on April
23, 2018. Subsequently, NPS has
identified additional research and
monitoring projects in southern Alaska
(SWAN region) with similar sources of
marine mammal disturbance and
potential effects. On October 29, 2018,
NMFS received an adequate and
complete revised application including
these additional research and
monitoring activities. These additional
activities were determined to be similar
in scope and impact to the original
proposed activities, and NMFS
PO 00000
Frm 00044
Fmt 4702
Sfmt 4702
64079
determined that publication of a revised
notice of receipt was not necessary for
the updated application.
Prior to this request for incidental
take regulations and subsequent Letters
of Authorization (LOA), we issued five
consecutive incidental harassment
authorizations (IHA) to NPS for
incidental take associated with the
GLBA NP ongoing gull and climate
monitoring activities. NPS was first
issued an IHA, valid for a period of one
year, effective on September 18, 2014
(79 FR 56065), and was subsequently
issued one-year IHAs for incidental take
associated with the same activities,
effective on March 24, 2015 (80 FR
28229), June 1, 2016 (77 FR 24471), May
20, 2017 (82 FR 24681), and February
15, 2018 (83 FR 6842). NPS has abided
by all of NMFS’s mitigation and
monitoring requirements in previous
activities for which take was authorized.
Description of the Specified Activity
Glacier Bay
NPS is proposing to conduct two
research projects within the GLBA NP
in southeast Alaska: (1) Glaucouswinged gull monitoring, and (2) the
maintenance of a weather station
operation for long-term climate
monitoring. NPS would conduct ground
and vessel surveys at six study sites
within GLBA NP for gull monitoring:
South Marble Island, Boulder Island,
Lone Island, Geikie Rock, Flapjack
Island, and Tlingit Point Islet. These
sites will be accessed up to five times
per year. In addition, NPS is requesting
permission to access Lone Island an
additional three times per year for
weather station maintenance and
operation bringing the total number of
site visits to Lone Island to eight. This
includes adding one additional trip for
any emergency repairs that may be
needed. Researchers accessing the
islands for gull monitoring and weather
station operation may cause behavioral
disturbance (Level B harassment) of
harbor seals. NPS expects that the
disturbance to harbor seals from both
projects will be limited to Level B
harassment.
The purpose for the above-mentioned
research activities are as follows. Gull
monitoring studies are mandated by a
Record of Decision of a Legislative
Environmental Impact Statement (LEIS)
(NPS 2010) which states that NPS must
initiate a monitoring program for
glaucous-winged gulls (Larus
glaucescens) to inform future native egg
harvest by the Hoonah Tlingit in Glacier
Bay, Alaska. Installation of a new
weather station on Lone Island was
conducted by the NPS in the spring of
E:\FR\FM\13DEP1.SGM
13DEP1
64080
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
2018 as one of several installations
intended to fill coverage gaps among
existing weather stations in GLBA NP
(NPS 2015a). In order to properly
maintain the newly installed weather
station, researchers must access the
Lone Island weather station site at least
twice a year for annual maintenance and
repairs.
SWAN
NPS is applying for an LOA to
conduct the SWAN marine bird and
mammal multi-species nearshore
surveys along the coastlines of Katmai
National Park and Preserve (KATM),
Kenai Fjords National Park (KEFJ), and
in Kachemak Bay (KBAY) in support of
long-term monitoring programs in these
regions of southwest Alaska. Occasional
disturbance of Steller sea lions and
harbor seals may occur during surveys.
Steller sea lion and harbor seal habitat
coincides with surveyed nearshore
transects. Please see NPS’s application
for established transect locations for
KATM and KEFJ and proposed transect
locations for KBAY. NPS expects that
the disturbance will be limited to Level
B harassment and will not result in
serious injury or death. SWAN also
seeks to foster further collaborations
with NOAA and share monitoring data
in the future.
Dates and Duration
amozie on DSK3GDR082PROD with PROPOSALS1
Glacier Bay
The specified activity would be valid
during the five-year period of validity
for these proposed regulations (March 1,
2019 through February 29, 2024).
Ground and vessel surveys for nesting
gulls will be conducted from May
through September on bird nesting
islands in GLBA NP (see Figure 1 of
LOA Application) and other suspected
gull colonies. There will be 1–3 ground
visits and 1–2 vessel surveys at each site
for a maximum of five visits per site.
Duration of surveys will be 30 minutes
to two hours each.
Maintenance of the Lone Island
weather station may begin March 1,
2019. To avoid the gull-nesting period,
all maintenance and emergency repairrelated site visits to this location are
planned to occur between March and
April during the first year, and October
to April in following years, but visits
could occur outside of this time period
if necessary with authorization from the
park Superintendent to ensure
protection of park resources and values.
Possible unanticipated station failures
requiring emergency repair will require
up to eight hours. Two planned
maintenance visits will require
approximately two hours per visit.

SWAN
NPS’s activities in the SWAN region
would be valid during the five year
period of validity for these proposed
regulations (March 1, 2019 through
February 29, 2024). Standardized
surveys of marine birds are proposed in
KATM and KEFJ between late June and
early July and are generally conducted
by two survey crews on independent
small vessels (5–8 m length) traveling at
speeds of 8–12 knots along randomly
selected sections of coastline that
represent independent transects. The
two crews operate independently and
do not survey the same transects. Winter
surveys are conducted in March and
consist of the same set of transects
surveyed in the summer months. Only
one region, either KATM or KEFJ, per
winter season is surveyed. Regions
surveyed in the winter are on a rotation.
Similar annual surveys are proposed in
KBAY, with summer surveys occurring
in June or July and no winter survey
proposed. The survey of each area takes
3–4 days to complete with both crews
operating.
Specified Geographical Region
Glacier Bay
The proposed study sites would occur
in the vicinity of the following
locations: South Marble, Boulder, Lone,
and Flapjack Islands, Tlinglit Point Islet,
and Geikie Rock in GLBA NP in
southeast Alaska (see Figure 1 of LOA
application). Each of these study sites
are located on the eastern side of the
park situated near Geikie Inlet and all
provide harbor seal habitat throughout
the year, however the highest presence
of seals occurs during the breeding and
molting season (May to October) (Lewis
et al., 2017). On Boulder and Flapjack
islands, the proposed gull monitoring
study sites are located on the north side
whereas harbor seal haulouts are
positioned on the south (Lewis et al.,
2017). Also, on Lone Island, harbor seals
are sited near tidal rocks off the
northeast tip of the island (ADEC, 2014),
whereas on Geikie Rock they are known
to be found throughout the entire site
due to its small size (Lewis 2017). NPS
will also conduct studies at South
Marble Island and Tlingit Point Islet;
however, there are no reported harbor
seal haulout sites at those locations.
South Marble Island is regularly
occupied by hauled out Steller sea lions,
but GLBA NP researchers have been
able to access the island previously
while maintaining 100 m minimum
distance from the Steller sea lions and
avoiding disturbance.

SWAN
The proposed surveys will occur at
two national parks, KATM and KEFJ, as
well as the nearby KBAY, in southwest
AK. Detailed maps of the survey
transects are available in the NPS’s LOA
application. Transects are conducted
100 or 150 m from shore and have a
total width of approximately 200 to 300
m centered on the vessel.
Detailed Description of Activities
Glacier Bay’s Glaucous-Winged Gull
Monitoring
Gull monitoring will be conducted
using a combination of ground and
vessel surveys by landing at specific
access points on the islands. NPS
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 during the period of May
through September.
Ground-based surveys for gull
monitoring will involve two trained
observers conducting complete nest
counts of the gull colonies. The survey
will encompass all portions of the gull
colony accessible to humans and thus
represent a census of the harvestable
nests. GPS locations of nests and
associated vegetation along with the
number of live and predated eggs will
be collected during at least one visit to
obtain precise nest locations to
characterize nesting habitat. On
subsequent surveys, nest counts will be
tallied on paper so observers can move
through the colony more quickly and
minimize disturbance. Ground surveys
will be discontinued after the first
hatched chick is detected to minimize
disturbance and mortalities of gulls.
During ground surveys, observers will
also record other bird and marine
mammal species in proximity to
colonies.
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 (kn) (4.6 miles per hour
(mph)). Ground surveys generally last
30 minutes (min) to two hours (hrs)
each depending on the size of the island
and the number of nesting gulls. During
ground surveys, Level B harassment of
harbor seals can occur from either
acoustic disturbance from motorboat
sounds or visual disturbance from the
presence of observers. Past monitoring
reports show that most takes (flushes or
movements greater than one meter) from
ground surveys occurred as vessels
approached a study site to perform a
survey. Takes usually occurred while
E:\FR\FM\13DEP1.SGM
13DEP1
64081
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
the vessel was 50–100 meters from the
island (NPS 2015b; NPS 2016).
Vessel-based surveys for gull
monitoring will be conducted from the
deck of a motorized vessel (10 to 12
meters) and will be used to count the
number of adult and fledgling gulls that
are visible from the water (Zador, 2001;
Arimitsu et al., 2007). Vessel surveys
provide a more reliable estimate of the
numbers of gulls in the colony than
ground surveys because NPS can count
nesting birds in areas that are
inaccessible by foot and because the
birds do not flush from the researchers’
presence. GLBA NP would conduct
these surveys by circling the islands at
approximately 100 m from shore while
counting the number of adult and chick
gulls as well as other bird and mammal
species present. Surveys can be from 30
min to two hrs in duration. During
vessel surveys, Level B harassment of
harbor seals can occur from either
acoustic disturbance from motorboat
sounds or visual disturbance from the
presence of observers. Past monitoring
reports show that most takes (flushes or
movements greater than one meter) from
vessel surveys occurred as the vessel
was 100 m from the island (NPS 2015b;
NPS 2016).
Glacier Bay’s Climate Monitoring
(Weather Station Maintenance)
To conduct climate monitoring and
weather station maintenance activities,
Lone Island will be accessed by a 10–
20 m motor vessel. Materials will be
carried by hand to the weather station
location. Station configuration and
maintenance is typical of Remote
Automated Weather Stations (RAWS)
operated by land management agencies
for weather and climate monitoring, fire
weather observation, and other uses.
The weather station consists of an 8-ft
monopole and associated guy lines. In
addition, there is a fuel cell and sealed
12V battery housed in a watertight
enclosure that provides power to the
station. Standard meteorological sensors
for measuring precipitation, wind,
temperature, solar radiation, and snow
depth are used. Data is housed in
internal memory and communicated via
satellite telemetry to the Wildland Fire
Management Institute where it is
relayed to a variety of repositories such
as the Western Regional Climate Center
in near real-time. It is possible that the
weather station can be accessed in a
fashion that will not disturb hauled out
harbor seals. However NPS is requesting
authorization to ensure its ability to
perform yearly maintenance of the
weather station.
SWAN Marine Bird and Marine
Mammal Surveys
SWAN standardized surveys of
marine birds are conducted in KATM
and KEFJ between late June and early
July and are generally conducted from
small vessels (5–8 m length) traveling at
speeds of 8–12 knots along randomly
selected sections of coastline that
represent independent transects. SWAN
is also proposing similar surveys be
implemented in KBAY in cooperation
with USGS and Gulf Watch Alaska. The
survey design consists of a series of
transects along shorelines such that a
minimum of 20 percent of an NPS park
shoreline is surveyed. Transects are
systematically selected beginning at a
random starting point from the pool of
contiguous 2.5–5 km transects that are
adjacent to the mainland or islands. The
transect width is 200–300 m, depending
on the elevation of the observer
platform, and the survey boat represents
the midpoint. There are two survey
teams, and each transect is surveyed by
one team of three. The boat operator
generally surveys the 100–150 m
offshore area of the transect, while a
second observer surveys the 100–150 m
nearshore area. The third team member
enters the observations into a laptop
running software specifically designed
for this type of surveying, and the third
team member can assist with
observations when needed. All marine
birds and mammals within the 200–300
m transect swath are identified and
counted. Detailed descriptions of
methods and procedures can be found
in the Marine Bird and Mammal Survey
SOP (Bodkin 2011).
Description of Marine Mammals in the
Area of the Specified Activity
Sections 3 and 4 of the LOA
application summarize available
information regarding status and trends,
distribution and habitat preferences,
and behavior and life history, of the
potentially affected species. Additional
information regarding population trends
and threats may be found in NMFS’s
Stock Assessment Reports (SAR; https://
www.fisheries.noaa.gov/national/
marine-mammal-protection/marinemammal-stock-assessments) and more
general information about these species
(e.g., physical and behavioral
descriptions) may be found on NMFS’s
website (https://
www.fisheries.noaa.gov/find-species).
Table 1 lists all species with expected
potential for occurrence within the
survey areas and summarizes
information related to the population or
stock, including regulatory status under
the MMPA and Endangered Species Act
(ESA) and potential biological removal
(PBR), where known. For taxonomy, we
follow the Committee on Taxonomy
(2017). PBR is defined by the MMPA as
the maximum number of animals, not
including natural mortalities, that may
be removed from a marine mammal
stock while allowing that stock to reach
or maintain its optimum sustainable
population (as described in NMFS’s
SARs). While no mortality is anticipated
or authorized here, PBR and annual
serious injury and mortality from
anthropogenic sources are included here
as gross indicators of the status of the
species and other threats. Marine
mammal abundance estimates presented
in this document represent the total
number of individuals that make up a
given stock or the total number
estimated within a particular study or
survey area. NMFS’s stock abundance
estimates for most species represent the
total estimate of individuals within the
geographic area, if known, that
comprises that stock. For some species,
this geographic area may extend beyond
U.S. waters. All managed stocks in this
region are assessed in NMFS’s U.S.
Alaska SARs (Muto et al., 2018). All
values presented in Table 1 are the most
recent available at the time of
publication and are available in the
2017 SARs (Muto et al., 2018).

All marine mammal species that
could potentially occur in the proposed
survey areas are included in Table 1.
While cetaceans, including humpback,
beluga, and killer whales, may be
present in nearby waters, NPS’s
activities are expected to result in
harassment only for hauled out
pinnipeds. Therefore, cetaceans are not
considered further in this analysis.
However, NPS does propose cetacean
avoidance measures as described in the
‘‘Proposed Mitigation’’ section below.
Finally, sea otters may be found
throughout the proposed project area.
However, sea otters are managed by the
U.S. Fish and Wildlife Service and are
not considered further in this document.
Steller Sea Lions
The Steller sea lion is the largest of
the eared seals, ranging along the North
Pacific Rim from northern Japan to
California, with centers of abundance
and distribution in the Gulf of Alaska
and Aleutian Islands. Steller sea lions
were listed as threatened range-wide
under the ESA on November 26, 1990
(55 FR 49204). Subsequently, NMFS
published a final rule designating
critical habitat for the species as a 20
nautical mile buffer around all major
haulouts and rookeries, as well as
associated terrestrial, air and aquatic
zones, and three large offshore foraging
areas (58 FR 45269; August 27, 1993). In
1997, NMFS reclassified Steller sea
lions as two distinct population
segments (DPS), or stocks, based on
genetic studies and other information
(62 FR 24345; May 5, 1997). Steller sea
lion populations that primarily occur
west of 144° W (Cape Suckling, Alaska)
comprise the western stock, while all
others comprise the eastern stock;
however, there is regular movement of
both stocks across this boundary
(Jemison et al., 2013). Upon this
reclassification, the western DPS, or
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
stock, was listed as endangered while
the eastern DPS, or stock, remained as
threatened (62 FR 24345; May 5, 1997)
and in November 2013, the eastern DPS
was delisted (78 FR 66140).
Steller sea lions are not known to
migrate, but individuals may disperse
widely outside the breeding season (late
May to early July). At sea, Steller sea
lions are commonly found from
nearshore habitats to the continental
shelf and slope. The western stock
breeds on rookeries in Alaska from
Prince William Sound west through the
Aleutian Islands. Steller sea lions use 38
rookeries and hundreds of haulouts
within their range in western Alaska
(Allen and Angliss 2013). The eastern
stock originates from rookeries east of
Cape Suckling, Alaska, and can be
found between southeast Alaska and
California.
SWAN
SWAN’s activities all occur west of
the 144° W line that splits the two
Steller sea lion stocks, but there is some
mixing across that boundary. Steller sea
lions impacted by NPS’ research and
monitoring activities could belong to
either stock, and it is not possible to
determine which stock a Steller sea lion
belongs to by simple observation. Both
stocks of Steller sea lions are therefore
considered in this analysis.
SWAN surveys occur in areas with
known Steller sea lion haulouts and
there are two rookeries in KEFJ (see
application). KATM and KEFJ
shorelines are both within Steller sea
lion critical habitat including the
aquatic zone (or buffer) that extends 37
kilometers (20 nautical miles) seaward
in all directions from each rookery and
major haulout. Critical habitat also
includes three large offshore foraging
areas: The Shelikof Strait area, the
Bogoslof area, and the Seguam Pass area
(58 FR 45269) with only the Shelikof
PO 00000
Frm 00047

Strait area relevant to this action. Steller
sea lions are sometimes present in
KBAY, but the area is not critical
habitat. Regulations prevent approach
by vessel to within three nautical miles
of major rookeries (50 CFR 224.103).
Glacier Bay
The temporal and/or spatial
occurrence of Steller sea lions is such
that take is not expected to occur in
GLBA NP research sites and researchers
would not approach Steller sea lions.
Steller sea lions which occur in GLBA
NP are generally found on South Marble
Island (see Figure 1 in the Application).
No disturbance of Steller sea lions is
expected from GLBA NP activities, so
their presence in the area is not
discussed beyond the information
provided here.
A total of five Steller sea lions have
been observed during the 2015, 2016,
and 2017 GLBA NP gull survey seasons
(climate monitoring did not take place
during these years) (NPS 2015b; NPS
2016; NPS 2017). However, all Steller
sea lions that were spotted were
observed outside the study area. Steller
sea lions are present in GLBA NP, but
are not generally seen on the islands
being researched. NPS has proposed
mitigation, including staying at least
100 m away from all Steller sea lions
(see Proposed Mitigation), which has
been found to be sufficient to avoid take
by Level B harassment due to Steller sea
lions’ tolerance of vessels and lack of
response to humans from a distance.
Harbor Seals
Harbor seals are the most abundant
marine mammal species found within
the action area and are present yearround. Harbor seals range from Baja
California north along the west coasts of
Washington, Oregon, California, British
Columbia, and Southeast Alaska; west
through the Gulf of Alaska, Prince
E:\FR\FM\13DEP1.SGM
13DEP1

William Sound, and the Aleutian
Islands; and north in the Bering Sea to
Cape Newenham and the Pribilof
Islands. The current statewide
abundance estimate for Alaskan harbor
seals is 205,090 (Muto et al., 2017),
based on aerial survey data collected
during 1998–2011. In 2010, harbor seals
in Alaska were partitioned into 12
separate stocks based largely on genetic
structure (Allen and Angliss, 2010).
Harbor seals have declined dramatically
in some parts of their range over the
past few decades, while in other parts
their numbers have increased or
remained stable over similar time
periods.
Harbor seals haul out on rocks, reefs,
beaches, and drifting glacial ice (Allen
and Angliss, 2014). They are nonmigratory; their local movements are
associated with tides, weather, season,
food availability, and reproduction, as
well as sex and age class (Allen and
Angliss, 2014; Boveng et al., 2012;
Lowry et al., 2001; Swain et al., 1996).
Pupping in Alaska generally takes place
in May and June; while molting
generally occurs from June to October.
Glacier Bay Stock/Icy Strait Stock
Harbor seals of Glacier Bay range from
Cape Fairweather southeast to Column
Point, extending inland to Glacier Bay,
Icy Strait, and from Hanus Reef south to
Tenakee Inlet (Muto et al., 2017). This
is the only stock that would be impacted
by research and monitoring activities in
GLBA NP. The Glacier Bay/Icy Strait
stock showed a negative population
trend from 1992 to 2008 in June and
August for glacial (¥7.7 percent/year;
¥8.2 percent/year) and terrestrial sites
(¥12.4 percent/year, August only)
(Womble et al., 2010 as cited in Muto
et al., 2017). Trend estimates by
Mathews and Pendleton (2006) were
similarly negative for both glacial and
terrestrial sites. Prior to 1993, seal
counts were up to 1,347 in the East Arm
of Glacier Bay; 2008 counts were fewer
than 200 (Streveler, 1979; Molnia, 2007
as cited in Muto et al., 2017). These
observed declines in harbor seals
resulted in new research efforts which
were initiated in 2004 and were aimed
at trying to further understand the
biology and ecology of seals and
possible factors that may have
contributed to the declines (e.g.,
Herreman et al. 2009, Blundell et al.
2011, Hueffer et al. 2012, Womble and
Gende 2013a, Womble et al. 2014), with
an emphasis on possible factors that
may have contributed to the declines.
The recent studies suggest that (1)
harbor seals in Glacier Bay are not
significantly stressed due to nutritional
constraints (Blundell et al. 2011), (2) the
clinical health and disease status of
seals within Glacier Bay is not different
than seals from stable or increasing
populations (Hueffer et al. 2012), and (3)
disturbance by vessels does not appear
to be a primary factor driving the
decline (Young 2009).
Long-term monitoring of harbor seals
on glacial ice has occurred in Glacier
Bay since the 1970s (Mathews and
Pendleton, 2006) and has shown this
area to support one of the largest
breeding aggregations in Alaska
(Steveler, 1979; Calambokidis et al.,
1987 as cited in Muto et al., 2015). After
a large scale retreat of the Muir Glacier
(more than 7 km), in the East Arm of
Glacier Bay, between 1973 and 1986 and
the subsequent grounding and cessation
64083
of calving in 1993, floating glacial ice
was greatly reduced as a haulout
substrate for harbor seals and ultimately
resulted in the abandonment of upper
Muir Inlet by harbor seals
(Calambokidis et al., 1987; Hall et al.,
1995; Mathews, 1995 as cited in Muto
et al., 2017). The most recent long-term
trend estimate for harbor seals at
terrestrial sites in Glacier Bay for the 22year period from 1992–2013 is ¥6.91
percent/year (SE = 0.40, 95% CI =
¥7.69, ¥6.13) (Womble et al. 2015).
This trend is less negative than previous
estimates stated in the paragraph above.
In addition, from 2004–2013, there was
a 10-year trend estimate of 9.64 percent
increase per year (SE = 1.66, 95% CI =
6.40, 12.89) (Womble et al., 2015).
Results from satellite telemetry
studies suggest that harbor seals travel
extensively beyond the boundaries of
Glacier Bay during the post-breeding
season (September–April); however,
harbor seals demonstrated a high degree
of inter-annual site fidelity (93 percent)
to Glacier Bay the following breeding
season (Womble and Gende 2013b).
Spatial and temporal regulations, for
vessels transiting in and near harbor
seal breeding areas, and operating
regulations, for vessels operating within
those areas, are all aimed at reducing
the impacts of human visitation.
Harbor seals from the Glacier Bay/Icy
Strait stock can be found hauled out at
four of the gull monitoring study sites
(Table 2). Seal counts from gull
monitoring surveys likely represent a
minimum estimate due to difficulty
observing marine mammals from a
vessel. Counts from gull monitoring
surveys are conducted during high tide
so fewer seals may be present.

As alluded to, there can be greater
numbers of seals on the survey islands
than what is detected by the NPS during
the gull surveys. Aerial survey
maximum counts show that harbor seals
sometimes haul out in large numbers at
all four locations (see Table 2 of the
application). However, harbor seals
hauled out at Flapjack Island are
VerDate Sep<11>2014

generally on the southern end whereas
the gull colony is on the northern end.
Similarly, harbor seals on Boulder
Island tend to haul out on the southern
end while the gull colony is located and
can be accessed on the northern end
without causing disturbance of harbor
seals. Aerial survey counts for harbor
seals are conducted during low tide

while ground and vessel surveys are
conducted during high tide which,
along with greater visibility during
aerial surveys, may also contribute to
the greater numbers of seals observed
during the aerial surveys because there
is more land available to use as a
haulout during low tide.

Prince William Sound Stock
The Prince William Sound stock
includes harbor seals both within and
adjacent to Prince William Sound
proper from approximately Cape
Fairweather to Elizabeth Island,
including the KEFJ survey area. Within
Prince William Sound proper, harbor
seals declined in abundance by 63
percent between 1984 and 1997 (Frost et
al. 1999). In Aialik Bay, adjacent to
Prince William Sound proper, there has
been a decline in pup production by 4.6
percent annually from 40 down to 32
pups born from 1994 to 2009 (HooverMiller et al. 2011). The current (2007–
2011) estimate of the Prince William
Sound population trend over a 5-year
period is +26 seals per year with a
probability that the stock is decreasing
of 0.56. The presence of an increasing
trend with a greater than .5 probability
of decreasing is due to skewness
impacting statistical estimates. This
occurrence is discussed further in Muto
et al. (2018).
From 1992–1997, results from a
satellite telemetry study showed Prince
William Sound harbor seals tended to
remain in or near Prince William
Sound. Juvenile seals were occasionally
found to range up to 300 to 500 km east
and west into the Gulf of Alaska. In June
and July, when SWAN region surveys
would occur, harbor seals tended to
have their smallest home range sizes,
remaining nearer to their haulout than
other times of year (Lowry et al. 2001).

Cook Inlet/Shelikof Strait Stock
16:36 Dec 12, 2018
Jkt 247001
This section includes a summary and
discussion of the ways that components
of the specified activity may impact
marine mammals and their habitat. The
‘‘Estimated Take’’ section later in this
document includes a quantitative
analysis of the number of individuals
that are expected to be taken by this
activity. The ‘‘Negligible Impact
Analysis and Determination’’ section
considers the content of this section, the
‘‘Estimated Take’’ section, and the
‘‘Proposed Mitigation’’ section, to draw
conclusions regarding the likely impacts
of these activities on the reproductive
success or survivorship of individuals
and how those impacts on individuals
are likely to impact marine mammal
species or stocks.
As previously stated, acoustic and
visual stimuli generated by motorboat
operations and the presence of
researchers have the potential to cause
Level B harassment of harbor seals
hauled out on Boulder, Lone, and
Flapjack Islands, and Geikie Rock
within GLBA NP. These same stimuli
generated by motorboat operations have
the potential to cause Level B
harassment of harbor seals and Steller
sea lions in KATM, KEFJ, and KBAY.
The following discussion provides
further detail on the potential visual and
acoustic disturbances harbor seals and
Steller sea lions may encounter during
the NPS’ research and monitoring
activities.
Human and Vessel Disturbance
The Cook Inlet/Shelikof Strait stock
includes harbor seals from
approximately Elizabeth Island to
Unimak Island, as well as those within
Cook Inlet. Multiple harbor seal
haulouts exist in KBAY and KATM
(London et al, 2015; Montgomery et al
2007). This stock of harbor seals would
be found in the KATM and KBAY
survey areas of SWAN’s activities. A
multi-year study of seasonal movements
and abundance of harbor seals in Cook
Inlet was conducted between 2004 and
2007. This study involved multiple
aerial surveys throughout the year, and
the data indicated a stable population of
harbor seals during the August molting
period (Boveng et al. 2011). Aerial
surveys along the Alaska Peninsula
present greater logistical challenges and
have therefore been conducted less
frequently. The current (2007–2011)
estimate of the Cook Inlet/Shelikof
Strait population trend is +313 seals per
year, with a probability of 0.38 that the
stock is decreasing (Muto et al. 2018).
VerDate Sep<11>2014
Potential Effects of the Specified
Activity on Marine Mammals and Their
Habitat
Harbor seals and Steller sea lions may
potentially experience behavioral
disruption rising to the level of
harassment from monitoring and
research activities, which may include
brief periods of airborne noise from
research vessels and visual disturbance
due to the presence and activity of the
researchers both on vessels and on land
during ground surveys. Disturbed
pinnipeds are likely to experience any
or all of these stimuli, and take may
occur due to any in both isolation or
combined with one another. Due to the
likely constant combination of visual
and acoustic stimuli resulting from the
presence of vessels and researchers, we
do not consider impacts from acoustic
and visual stimuli separately.
Disturbances resulting from human
activity can impact short- and long-term
pinniped haul out behavior (Renouf et
al., 1981; Schneider and Payne, 1983;
Terhune and Almon, 1983; Allen et al.,
1984; Stewart, 1984; Suryan and
Harvey, 1999; and Kucey and Trites,
PO 00000
Frm 00049
Fmt 4702
Sfmt 4702
2006). Disturbance includes a variety of
effects, including subtle to conspicuous
changes in behavior, movement, and
displacement. Reactions to sound, if
any, depend on the species, state of
maturity, experience, current activity,
reproductive state, time of day, and
many other factors (Richardson et al.,
1995; Wartzok et al., 2004; Southall et
al., 2007; Weilgart, 2007). These
behavioral reactions from marine
mammals are often shown as: changing
durations of surfacing and dives, or
moving direction and/or speed;
reduced/increased vocal activities;
changing/cessation of certain behavioral
activities (such as socializing or
feeding); visible startle response or
aggressive behavior; avoidance of areas;
and/or flight responses (e.g., pinnipeds
flushing into the water from haulouts or
rookeries). If a marine mammal does
react briefly to human presence by
changing its behavior or moving a small
distance, the impacts of the change are
unlikely to be significant to the
individual, let alone the stock or
population. However, if visual stimuli
from human presence displaces marine
mammals from an important feeding or
breeding area for a prolonged period,
impacts on individuals and populations
could be significant (e.g., Lusseau and
Bejder, 2007; Weilgart, 2007).
Visual stimuli resulting from the
presence of researchers and vessels have
the potential to result in take of harbor
seals and Steller sea lions on the
research islands and coasts where these
pinnipeds haul out. The characteristics
of these stimuli differ between the
GLBA NP and SWAN activities. In
SWAN’s activities, vessels move at
faster speeds (8–12 kn, vs 2–3 kn for
GLBA NP) but are present for a short
time period transiting through an area
and at a consistent distance.
Alternatively, while GLBA NP vessels
are slower, they must approach islands
where pinnipeds may be hauled out,
and both the vessel and researchers will
be present for a longer period of time.
As noted, harbor seals and Steller sea
lions can exhibit a behavioral response
(e.g., including alert behavior,
movement, vocalizing, or flushing) to
visual stimuli. NMFS does not consider
the lesser reactions (e.g., alert behavior
such as raising a head) to constitute
harassment. Table 3 displays NMFS’s
three-point scale that categorizes
pinniped disturbance reactions by
severity. Observed behavior falling
within categories two and three would
be considered level B harassment. GLBA
NP is able to record these behaviors for
all observed pinnipeds. Because of the
nature of their survey, SWAN
E:\FR\FM\13DEP1.SGM
13DEP1
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
researchers will only be able to record
the total number of observed pinnipeds,
and those which show an easily
observable level 3 response (flushing).
With these numbers and previous
monitoring information from GLBA NP,
NPS and NMFS should be able to
estimate the total number of takes by
64085
Level B harassment resulting from
SWAN monitoring.

Seal head orientation or brief movement in response to disturbance, which may include turning
head towards the disturbance, craning head and neck while holding the body rigid in a ushaped position, changing from a lying to a sitting position, or brief movement of less than
twice the animal’s body length. Alerts would be recorded, but not counted as a ‘take’.
Movements in response to the source of disturbance, ranging from short withdrawals at least
twice the animal’s body length to longer retreats over the beach or, if already moving, a
change of direction of greater than 90 degrees. These movements would be recorded and
counted as a ‘take’.
All retreats (flushes) to the water. Flushing into the water would be recorded and counted as a
‘take’.
Upon the occurrence of low-severity
disturbance (i.e., the approach of a
vessel or person as opposed to an
explosion or sonic boom), pinnipeds
typically exhibit a continuum of
responses, beginning with alert
movements (e.g., raising the head),
which may then escalate to movement
away from the stimulus and possible
flushing into the water. Flushed
pinnipeds typically re-occupy the same
haulout within minutes to hours of a
stimulus (Allen et al., 1984 (Johnson
and Acevedo-Gutierrez, 2007). As a
result, a minimal number of animals
may be taken more than once during the
proposed survey activities so the
number of takes likely represents
exposures. In the case of GLBA NP,
because there will be no more than five
annual visits to three gull study sites
and no more than eight annual visits to
one other survey site, it is expected that
individual harbor seals at Boulder
Island, Flapjack Island, and Geike Rock
will be disturbed no more than five
times per year and no more than eight
times per year on Lone Island. For
SWAN’s activities, KATM, KEFJ, and
KBAY are each visited during the
summer. There is a winter survey
conducted each year at either KATM or
KEFJ. Therefore individual harbor seals
and Stellar sea lions at these locations
will be disturbed no more than two
times per year.
Numerous studies have shown that
human activity can flush pinnipeds off
haulout sites and beaches (Kenyon,
1972; Allen et al., 1984; Calambokidis et
al., 1991; Suryan and Harvey, 1999; and
Mortenson et al., 2000, Mathews, 2000).
In 1997, Henry and Hammill (2001)
conducted a study to measure the
impacts of small boats (i.e., kayaks,
canoes, motorboats and sailboats) on
harbor seal haul out behavior in Me´tis
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
Bay, Quebec, Canada. During that study,
the authors noted that the most frequent
disturbances (n=73) were caused by
lower speed, lingering kayaks and
canoes (33.3 percent) as opposed to
motorboats (27.8 percent) conducting
high speed passes. The seals flight
reactions could be linked to a surprise
factor by kayaks-canoes, which
approach slowly, quietly and low on
water making them look like predators.
However, the authors note that once the
animals were disturbed, there did not
appear to be any significant lingering
effect on the recovery of numbers to
their pre-disturbance levels. In
conclusion, the study showed that boat
traffic at current levels has only a
temporary effect on the haul out
behavior of harbor seals in the Me´tis
Bay area.
In 2004, Johnson and AcevedoGutierrez (2007) evaluated the efficacy
of buffer zones for watercraft around
harbor seal haulout sites on Yellow
Island, Washington State. The authors
estimated the minimum distance
between the vessels and the haulout
sites; categorized the vessel types; and
evaluated seal responses to the
disturbances. During the course of the
seven-weekend study, the authors
recorded 14 human-related
disturbances, which were associated
with stopped powerboats and kayaks.
During these events, hauled out seals
became noticeably active and moved
into the water. The flushing occurred
when stopped kayaks and powerboats
were at distances as far as 453 and 1,217
ft (138 and 371 m) respectively. The
authors note that the seals were
unaffected by passing powerboats, even
those approaching as close as 128 ft (39
m), possibly indicating that the animals
had become tolerant of the brief
presence of the vessels and ignored

them. The authors reported that on
average, the seals quickly recovered
from the disturbances and returned to
the haulout site in less than or equal to
60 minutes. Seal numbers did not return
to pre-disturbance levels within 180
minutes of the disturbance less than one
quarter of the time observed. The study
concluded that the return of seal
numbers to pre-disturbance levels and
the relatively regular seasonal cycle in
abundance throughout the area counter
the idea that disturbances from
powerboats may result in site
abandonment (Johnson and AcevedoGutierrez, 2007). Specific reactions from
past NPS gull monitoring surveys are
detailed in this proposed rule’s
Estimated Take Section.
Vessel Strike
Glacier Bay
The probability of vessel and marine
mammal interactions (i.e., motorboat
strike) occurring during the proposed
research activities is unlikely due to the
motorboat’s slow operational speed,
which is typically 2 to 3 kn (2.3 to 3.4
mph) and the researchers continually
scanning the water for marine mammals
presence during transit to the islands.
Thus, NMFS does not anticipate that
strikes or collisions would result from
the movement of the motorboat.
SWAN
SWAN’s survey vessels move at
higher speeds, 8 to 12 kn, than those
used in the proposed GLBA NP
activities, but vessel and marine
mammal interactions are still unlikely
because the on board researchers are
constantly scanning the water for
marine mammal presence. For SWAN’s
activities, NMFS does not anticipate any
strikes or collisions between vessels and
marine mammals.

Harbor Seal Pupping
Glacier Bay
During the harbor seal breeding (MayJune) and molting (August) periods, ∼66
percent of seals in Glacier Bay inhabit
the primary glacial ice site and ∼22
percent of seals are found in and
adjacent to a group of islands in the
southeast portion of Glacier Bay. At the
proposed GLBA NP study sites, in 2016
only one pup was observed and no pups
were observed during project activities
in 2017 and 2015. Pups have been
observed during NPS aerial surveys
during the pupping seasons (conducted
during low tide), but in few numbers
(see Table 4). NMFS does not anticipate
that the proposed activities would result
in separation of mothers and pups as
pups are rarely seen at the study sites.

SWAN
Based on aerial surveys between 2003
and 2005, the upper portions of KBAY
had high harbor seal pup abundance
during the peak pupping season (June)
(Boveng at al, 2011). Proposed KBAY
survey transects occur in this area of
high abundance (See Figure 5 in LOA
application). Boveng et al (2011) found
that within Cook Inlet, June harbor seal
pup abundance in an individual survey
unit correlated positively with June
adult abundance in that unit. Therefore,
based on the anticipated presence of
adult harbor seals, there are also likely
pups present at sites in KATM and KEFJ
during the pupping season (June).
Despite the presence of pups, SWAN’s
research and monitoring activities are
expected to result in minimal
disturbance to the hauled out harbor
seals of all life stages due to the distance
and duration of the vessel’s presence
(see Proposed Mitigation), and NMFS
does not anticipate that the proposed
activities would result in separation of
mothers and pups.

During the Steller sea lion pupping
season (May–July), mothers spend time
both on land with their pups and at sea
foraging. Because SWAN’s proposed
surveys avoid transects that pass Steller
sea lion rookeries, NMFS does not
anticipate any impacts on hauled out
Steller sea lion mothers and their pups.
Summary
Based on studies described here and
previous monitoring reports from GLBA
NP (Discussed further in the Estimated
Take Section), we anticipate that any
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
pinnipeds found in the vicinity of the
proposed projects in both GLBA NP and
the SWAN region could have short-term
behavioral reactions (i.e., may result in
marine mammals avoiding certain areas)
due to noise and visual disturbance
generated by: (1) Motorboat approaches
and departures and (2) human presence
during research and monitoring
activities. We would expect the
pinnipeds to return to a haulout site
within minutes to hours of the stimulus
based on previous research (Allen et al.,
1984). Pinnipeds may be temporarily
displaced from their haulout sites, but
we do not expect that the pinnipeds
would permanently abandon a haulout
site during the conduct of the proposed
research as activities are short in
duration (brief transit through an area to
up to two hours), and previous surveys
have demonstrated that pinnipeds have
returned to their haulout sites and have
not permanently abandoned the sites.
NMFS does not anticipate that the
proposed activities would result in the
injury, serious injury, or mortality of
pinnipeds. NMFS does not anticipate
that vessel strikes would result from the
movement of the motorboat. The
proposed activities will not result in any
permanent impact on habitats used by
marine mammals, including prey
species and foraging habitat.
Marine Mammal Habitat
NMFS does not anticipate that the
proposed operations in GLBA NP or the
SWAN region would result in any
effects on the habitats used by the
marine mammals in the proposed area,
including the food sources they use (i.e.,
fish and invertebrates). The main impact
associated with the proposed activity
will be temporarily elevated noise levels

Frm 00051
Fmt 4702
Sfmt 4702
from motorboats and human
disturbance on marine mammals
potentially leading to temporary
displacement from a site, previously
discussed in this proposed rule. NPS’
LEIS for gull monitoring surveys in
GLBA NP concluded that the activities
do not result in the loss or modification
to marine mammal habitat (NPS 2010).
Additionally, any minor habitat
alterations stemming from the
maintenance of NPS’ weather station
will be located in an area that will not
impact marine mammals. SWAN’s
activities in KATM and KEFJ do occur
in Steller sea lion critical habitat, but
will have minimal impact due to the
nature of the disturbance and explicit
avoidance of the most sensitive areas
(rookeries). In all, the proposed
activities in both GLBA NP and the
SWAN region will not result in any
permanent impact on habitats used by
marine mammals, including prey
species and foraging habitat.
Estimated Take
This section provides an estimate of
the number of incidental takes proposed
for authorization through this IHA,
which will inform both NMFS’s
consideration of whether the number of
takes is ‘‘small’’ and the negligible
impact determination.
Harassment is the only type of take
expected to result from these activities.
Except with respect to certain activities
not pertinent here, section 3(18) of 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
E:\FR\FM\13DEP1.SGM

wild by causing disruption of behavioral
patterns, including, but not limited to,
migration, breathing, nursing, breeding,
feeding, or sheltering (Level B
harassment).
Authorized takes would be by Level B
harassment only, in the form of
disruption of behavioral patterns for
individual marine mammals resulting
from exposure to motorboats and the
presence of NPS personnel. Based on
the nature of the activity and proposed
mitigation measures, Level A
harassment is neither anticipated nor
proposed to be authorized. As described
previously, no mortality is anticipated
or proposed to be authorized for this
activity. Below we describe how the
take is estimated.
Glacier Bay
In GLBA NP, harbor seals may be
disturbed when vessels approach or
researchers go ashore for the purpose of
monitoring gull colonies and for the
maintenance of the Lone Island weather
tower. Harbor seals tend to haul out in
small numbers at study sites. Using
monitoring report data from 2015 to
2017 (see raw data from Tables 1 of the
2017, 2016 and 2015 Monitoring
Reports, which are available online at:
https://www.fisheries.noaa.gov/
national/marine-mammal-protection/
incidental-take-authorizations-researchand-other-activities), the average
number of harbor seals per survey visit
was calculated to estimate the
approximate number of seals observers
would find on any given survey day. As
a result, the following averages were
determined for each island: Boulder
Island—average 3.45 seals, Flapjack
Island—average 10.10 seals, Geikie
Rock—average 9.58 seals, and Lone
Island average of 18.91 seals (See Table
5). Estimated take for gull and climate
monitoring was calculated by
multiplying the average number of seals
observed during past gull monitoring
surveys (2015–2017) by the number of
total site visits. This includes five
annual visits to Boulder Island, Flapjack
Island, and Geikie Rock and eight
64087
annual visits to Lone Island (to include
three site visits for climate monitoring
activities). Therefore, the total estimated
annual incidents of harassment equals
267 which totals to 1,335 takes during
the entire five years of the proposed
activities (See Table 5).
During climate monitoring, which is
expected to take place from March to
April and October to February, seal
numbers are expected to dramatically
decline within the action area. Although
harbor seal survey data within GLBA NP
is lacking for the months of October
through February, results from satellite
telemetry studies suggest that harbor
seals travel extensively beyond the
boundaries of GLBA NP during the postbreeding season (September-April)
(Womble and Gende, 2013b). Therefore,
using the latest observation data from
past gull monitoring activities (that
occurred from May to September) is
applicable when estimating take for
climate monitoring activities, as it will
provide the most conservative estimates.

The estimated number of takes by Level
B harassment included in Table 6 are
based on numbers of pinnipeds
observed from a similar survey of
KATM and KEFJ in 2013. In this survey,
researchers observed an estimated 100
harbor seals and 100 Steller sea lions
during each of the KATM and KEFJ
surveys. Data from 2013 surveys were
used to estimate take because in 2013,
most of the transects were able to be
completed. Thus, 2013 data offers the
most conservative count-based estimate.

Based on pinnipeds observed in 2013,
NPS estimates that each year, across the
three survey sites, SWAN’s activities
will result in take by Level B
harassment of 300 harbor seals and 200
Steller sea lions. The observed number
of harbor seals has been increased by
100 to account for the previously not
surveyed KBAY, resulting in an
estimated 1500 harbor seal and 1000
Steller sea lion takes by Level B
harassment across the five years. For
harbor seals, NPS estimates that 100
individuals will experience take by
Level B harassment in each survey area
each year. Annually, that would mean
200 harbor seal takes by Level B
harassment in the Cook Inlet/Shelikof
Strait stock (1000 over 5 years), and 100
harbor seal takes by Level B harassment
from the Prince William Sound stock
(500 over 5 years). For Steller sea lion
takes by Level B harassment, NPS
estimates that 100 individuals will
experience take by Level B harassment
each year in KATM and KEFJ. However,
no takes by Level B harassment will
occur in KBAY because Steller sea lions
are not common in KBAY. For
simplicity, NMFS assumes and analyzes
the impacts of the full Steller sea lion
take on both the eastern and western
stocks. Because these estimates are
based on observations of pinnipeds and
not harassments, NMFS considers the
estimated numbers of take by Level B
harassment presented in Table 6

Effects of Specified Activities on
Subsistence Uses of Marine Mammals
The availability of the affected marine
mammal stocks or species for
subsistence uses may be impacted by
this activity, though this is not an
anticipated outcome. The subsistence
uses that may be affected and the
potential impacts of the activity on
those uses are described below.
Measures included in these proposed
regulations to reduce the impacts of the
activity on subsistence uses are
identical to those which minimize
disturbance of pinnipeds as described in
the Proposed Mitigation section. Last,
the information from this section and
the Proposed Mitigation section is
analyzed to determine whether the
necessary findings may be made in the
Unmitigable Adverse Impact Analysis
and Determination section.
Subsistence harvest of pinnipeds is
prohibited in GLBA NP, KATM, and
KEFJ but it does occur in nearby areas
outside park boundaries. Native
communities near KBAY, including
Homer, Seldovia, Nanwalek, and Port
Graham harvested an estimated 32
harbor seals and 3 Steller sea lions in
2007 (Wolfe et al. 2009). It is not known
exactly where these pinnipeds were
harvested but some of them could
potentially have been harvested in
KBAY. 2007 harvest of both Steller sea
lions and harbor seals was at a low
point in June and July when SWAN’s
surveys would occur in KBAY.
Additionally, the disturbance to
pinnipeds caused by NPS’s activities is
limited to non-lethal take by Level B
harassment and is temporary and short
in duration. Because the subsistence
harvest is separated in time and space
from NPS’s proposed activities, and the
disturbance should not result in
anything other than short term (minutes
to hours) avoidance of haulouts, there
should be no impacts on subsistence
harvest.
101(a)(5)(A) of the MMPA, NMFS must
set forth the permissible methods of
taking pursuant to such activity, ‘‘and
other means of effecting the least
practicable 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.
NMFS regulations require applicants for
ITAs to include information about the
availability and feasibility (economic
and technological) of equipment,
methods, and manner of conducting
such activity or other means of effecting
the least practicable adverse impact
upon the affected species or stocks and
their habitat (50 CFR 216.104(a)(11)).
In evaluating how mitigation may or
may not be appropriate to ensure the
least practicable adverse impact on
species or stocks and their habitat, as
well as on subsistence uses where
applicable, we carefully consider two
primary factors:
(1) The manner in which, and the
degree to which, the successful
implementation of the measure(s) is
expected to reduce impacts to marine
mammals, marine mammal species or
stocks, and their habitat. This considers
the nature of the potential adverse
impact being mitigated (likelihood,
scope, range). It further considers the
likelihood that the measure will be
effective if implemented (probability of
accomplishing the mitigating result if
implemented as planned) the likelihood
of effective implementation (probability
of implementing as planned); and
(2) The practicability of the measures
for applicant implementation, which
may consider such things as cost,
impact on operations, and, in the case
of a military readiness activity,
personnel safety, practicality of
implementation, and impact on the
effectiveness of the military readiness
activity.

implement during the proposed
research, on the following: (1) Protocols
used during previous gull research
activities as required by our previous
authorizations for these activities; and
(2) recommended best practices in
Womble et al. (2013a); Richardson et al.
(1995); and Weir and Dolman (2007).
To reduce the potential for
disturbance from acoustic and visual
stimuli associated with gull and climate
monitoring activities within GBLA NP,
NPS has proposed to implement the
following mitigation measures for
marine mammals:
Pre-Survey Monitoring
Before all surveys, the lead NPS
biologist will instruct additional survey
crew on appropriate conduct when in
the vicinity of hauled-out marine
mammals. This training shall brief
survey personnel on marine mammals
(inclusive of identification as needed,
e.g., neonates). Prior to deciding to land
onshore to conduct gull and climate
monitoring, 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 presurvey monitoring. If offshore predators,
harbor seal pups of less than one week
of age (i.e., neonates), or Steller sea lions
are observed, researchers will follow the
protocols for site avoidance discussed
below. If neither of these instances
occur, researchers will then perform a
controlled landing on the survey site.
Site Avoidance
If a harbor seal pup less than one
week old (i.e,. neonates) or a harbor seal
predator (i.e., killer whale) is observed
near or within the action area,
researchers will not go ashore to
conduct gull or climate monitoring
activities. Also, if Steller sea lions are
observed within or near the study site,
researchers will maintain a distance of
E:\FR\FM\13DEP1.SGM
13DEP1
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
at least 100 m from the animals at all
times.
implement the following mitigation
measures for marine mammals:
Controlled Landings
The researchers would determine
whether to approach an island study
site based on type of animals present.
Researchers would approach the island
by motorboat at a speed of
approximately 2 to 3 kn (2.3 to 3.4
mph). This would provide enough time
for any marine mammals present to
slowly enter the water without panic
(flushing). The researchers would also
select a pathway of approach farthest
from the hauled-out harbor seals to
minimize disturbance.
Disturbance Reduction Protocols
While surveying study sites, the
researchers will maintain a vessel
distance of 100 to 150 m from shorelines
at all times. If hauled out Steller sea
lions and harbor seals are observed, the
survey would maintain speed and
minimum distance from the haulout to
avoid startling. Additionally the survey
will be attempted from a distance
greater than 150 m, if conditions allow
proper execution of the survey at that
distance.
Minimize Predator Interactions
During pre-survey monitoring on
approach to a site, NPS will observe the
surrounding area for predators. If the
researchers visually observe marine
predators (i.e., killer whales) present
within a one mile radius of hauled-out
marine mammals, the researchers would
not approach the study site.
Disturbance 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.
amozie on DSK3GDR082PROD with PROPOSALS1
Whale Avoidance
Although humpback whales and killer
whales are not expected to be impacted
by the proposed activities at GLBA NP,
avoidance measures will be taken if
humpback whales or killer whales are
observed. Based on regulations (81 FR
62018; September 8, 2016), NPS will
avoid operation of a motor vessel within
1⁄4 nautical mile of a whale. If
accidentally positioned within 1⁄4
nautical mile of a whale, researchers
will slow the vessel speed to 10 knots
or less and maintain course away from
the whale until at least 1⁄4 nautical mile
of separation exists.
SWAN
NPS has based the mitigation
measures which they propose to
implement at SWAN on the following:
(1) Protocols used during previous
authorizations for similar GLBA NP
research; (2) recommended best
practices in Womble et al. (2013a);
Richardson et al. (1995); and Weir and
Dolman (2007); and (3) experience of
SWAN researchers in previous surveys.
To reduce the potential for
disturbance from acoustic and visual
stimuli associated with SWAN’s
surveys, NPS has proposed to
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
Rookery Avoidance
SWAN will avoid transects that pass
known Steller sea lion rookery beaches
in order to minimize disturbance of
these rookeries and the surrounding
critical habitat.
Whale Avoidance
Although humpback and beluga
whales are not expected to be impacted
by SWAN’s proposed work, avoidance
measures will be taken if these species
are observed. Based on regulations (81
FR 62018; September 8, 2016), SWAN
will avoid operation of a motor vessel
within 1⁄4 mile of a whale. If
accidentally positioned within 1⁄4
nautical mile of a whale, researchers
will slow the vessel speed to 10 knots
or less and maintain course away from
the whale until at least 1⁄4 nautical mile
of separation exists.
Mitigation Conclusions
Based on our evaluation of the
applicant’s proposed measures, as well
as other measures considered by NMFS,
NMFS has preliminarily 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, areas of similar
significance, and on the availability of
such species or stock for subsistence
uses.
Proposed Monitoring and Reporting
In order to issue an ITA for an
activity, section 101(a)(5)(A) 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
PO 00000
Frm 00054

populations of marine mammals that are
expected to be present in the proposed
action area. Effective reporting is critical
both to compliance as well as ensuring
that the most value is obtained from the
required monitoring.
Monitoring and reporting
requirements prescribed by NMFS
should contribute to improved
understanding of one or more of the
following:
• Occurrence of marine mammal
species or stocks in the area in which
take is anticipated (e.g., presence,
abundance, distribution, density);
• Nature, scope, or context of likely
marine mammal exposure to potential
stressors/impacts (individual or
cumulative, acute or chronic), through
better understanding of: (1) Action or
environment (e.g., source
characterization, propagation, ambient
noise); (2) affected species (e.g., life
history, dive patterns); (3) co-occurrence
of marine mammal species with the
action; or (4) biological or behavioral
context of exposure (e.g., age, calving or
feeding areas);
• Individual marine mammal
responses (behavioral or physiological)
to acoustic stressors (acute, chronic, or
cumulative), other stressors, or
cumulative impacts from multiple
stressors;
• How anticipated responses to
stressors impact either: (1) Long-term
fitness and survival of individual
marine mammals; or (2) populations,
species, or stocks;
• Effects on marine mammal habitat
(e.g., marine mammal prey species,
acoustic habitat, or other important
physical components of marine
mammal habitat); and
• Mitigation and monitoring
effectiveness.
SWAN
NPS proposes to conduct marine
mammal monitoring during the SWAN
activities, in order to implement the
mitigation measures that require realtime monitoring and to gain a better
understanding of marine mammals and
their impacts to the project’s activities.
Because the activity is a survey of
marine birds and mammals in the area,
researchers will naturally be monitoring
the area for pinnipeds or other marine
mammals during all activities.
Monitoring activities will consist of
conducting and recording observations
of pinnipeds within the vicinity of the
proposed research areas. The
monitoring notes would provide dates,
transect location, species, numbers of
animals present within the transect, and
numbers of pinnipeds that flushed into
the water.
E:\FR\FM\13DEP1.SGM
13DEP1
64090
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
The method for recording
disturbances follows those in Mortenson
(1996). For NPS’ activities in the SWAN
region, pinniped disturbances would be
based on a three-point scale that
represents an increasing response to the
disturbance (Table 3). Because SWAN
surveys are conducted at speed,
researchers will be able to record the
total number of each pinniped species
observed and the number of Level 3
(Flushing) responses that occur, but not
other, less noticeable disturbance
responses.
SWAN does not have previous
monitoring aimed specifically at
recording and quantifying marine
mammal disturbance. Similarity
between the GLBA NP and SWAN
proposed activities for this proposed
rule suggest mitigation measures based
on relevant portions of previous GLBA
NP authorizations will provide the
means of effecting the least practicable
impact on the species or stock in the
SWAN activity.
GLBA NP
NPS proposes to conduct marine
mammal monitoring during the present
GLBA NP project, in order to implement
the mitigation measures that require
real-time monitoring and to gain a better
understanding of marine mammals and
their impacts to the project’s activities.
In addition, NPS’s monitoring plan is
guiding additional monitoring effort
designed to answer questions of interest
regarding pinniped usage of GLBA NP
haulouts and the effects of NPS’s
activity on these local populations. The
researchers will monitor the area for
pinnipeds during all research activities.
Monitoring activities will consist of
conducting and recording observations
of pinnipeds within the vicinity of the
proposed research areas. The
monitoring notes would provide dates,
location, species, the researcher’s
activity, behavioral state, numbers of
animals that were alert or moved greater
than one meter, and numbers of
pinnipeds that flushed into the water.
The method for recording
disturbances follows those in Mortenson
(1996). NPS activities in GLBA NP
would record pinniped disturbances on
a three-point scale that represents an
increasing response to the disturbance
(Table 3). Both a level 2 and level 3
response would be recorded as a take by
Level B harassment. NPS will record the
time, source, and duration of the
disturbance, as well as an estimated
distance between the source and
haulout.
Previous Monitoring Results
NPS has complied with the
monitoring requirements under the
previous GLBA NP authorizations.
NMFS posted the 2017 report on our
website at https://
www.fisheries.noaa.gov/national/
marine-mammal-protection/incidentaltake-authorizations-research-and-otheractivities and the results from the
previous NPS monitoring reports
support our findings that the mitigation
measures required under the 2014—
2017 Authorizations provide the means
of effecting the least practicable impact
on the species or stock in the GLBA NP
activity. During the last 3 years of GLBA
NP activity, approximately a third of all
observed harbor seals have flushed in
response to these activities (37 percent
in 2015, 37 percent in 2016, and 38
percent in 2017). The following
narratives provide a detailed account of
each of the past 3 years of monitoring
for the GLBA NP activity (Summarized
in Table 7):
In 2017, of the 86 harbor seals that
were observed: 33 flushed in to the
water, 0 became alert but did not move
>1 m, and 0 moved >1 m but did not
flush into the water. In all, no harbor
seal pups were observed. On two
occasions, harbor seals were flushed
into the water when islands were
accessed for gull surveys. In these
instances, the vessel approached the
island at a very slow speed and most of
the harbor seals flushed into the water
at approximately 150—185 m. On two
events, harbor seals were observed
hauled out on Boulder Island and not
disturbed due to their distance from the
survey area. In addition, during two premonitoring surveys conducted for Lone
Island, harbor seals were observed
hauled out and the survey was not
conducted to prevent disturbance of
harbor seals.
In 2016, of the 216 harbor seals that
were observed: 77 Flushed in to the
water; 3 became alert but did not move
>1 m, and 17 moved >1 m but did not
flush into the water. On five occasions,
harbor seals were flushed into the water
when islands were accessed for gull
surveys. In these instances, the vessel
approached the island at a very slow
speed and most of the harbor seals
flushed into the water at approximately
50–100 m. In four instances, fewer than
25 harbor seals were present, but in one
instance, 41 harbor seals were observed
flushing into the water when NPS first
saw them as they rounded a point of
land in kayaks accessing Flapjack
Island. In five instances, harbor seals
were observed hauled out and not
disturbed due to their distance from the
survey areas.
In 2015, of the 156 harbor seals that
were observed: 57 Flushed in to the
water; 25 became alert but did not move
>1 m, and 0 moved >1 m but did not
flush into the water. No pups were
observed. On 2 occasions, harbor seals
were observed at the study sites in
numbers <25 and the islands were
accessed for gull surveys. In these
instances, the vessel approached the
island at very slow speed and most of
the harbor seals flushed into water at
approximately 200 m (Geikie 8/5/15)
and 280 m (Lone, 8/5/15). In one
instance, (Lone, 6/11/15) NPS counted
20 harbor seals hauled out during the
initial vessel-based monitoring, but once
on the island, NPS observed 33 hauled
out seals. When NPS realized the
number of seals present, they ceased the
survey and left the area, flushing 13
seals into the water.

Glacier Bay
NPS actively monitors harbor seals at
breeding and molting haulout locations
to assess trends over time (e.g., Mathews
& Pendleton, 2006; Womble et al. 2010,
Womble and Gende, 2013b). NPS’s
monitoring plan is guiding additional
monitoring effort designed to answer
questions of interest regarding pinniped
usage of GLBA NP haulouts and the
effects of NPS’s activity on these local
populations. This monitoring program
involves collaborations with biologists
from the Alaska Department of Fish and
Game, and the NMFS Alaska Fisheries
Science Center. NPS will continue these
collaborations and encourage continued
or renewed monitoring of marine
mammal species. NPS will coordinate
with state and Federal marine mammal
biologists to determine what additional
data or observations may be useful for
monitoring marine mammals and
haulouts in GLBA NP. Additionally,
NPS would report vessel-based counts
of marine mammals, branded, or injured
animals, and all observed disturbances
to the appropriate state and Federal
agencies.
SWAN
NPS is establishing a monitoring
program for pinnipeds in the SWAN
region through its marine bird and
marine mammal surveys. NPS will also
coordinate with state and Federal
marine mammal biologists to determine
what additional data or observations
may be useful for monitoring marine
mammals and haul outs in the SWAN
survey areas.
SWAN has been conducting nearshore
coastal surveys along the KATM and
KEFJ since 2006 and 2007, respectively
(Coletti et al., 2018). SWAN collaborates
closely with U.S. Geological Survey,
U.S. Fish and Wildlife Service, the
University of Alaska Fairbanks and
others under the Gulf Watch Alaska
(https://www.gulfwatchalaska.org/)
program, primarily funded by the Exxon
Valdez Oil Spill Trustee Council.
SWAN will continue these
collaborations and encourage continued
or renewed monitoring of marine
mammal species. Additionally, NPS
will report vessel-based counts of
marine mammals, branded or injured
animals, and all observed disturbances
to state and Federal agencies.
Reporting
SWAN and GLBA NP are each
required to submit separate draft annual
reports on all activities and marine
mammal monitoring results to NMFS
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
within ninety days following the end of
its monitoring period. These reports will
include a summary of the information
gathered pursuant to the monitoring
requirements set forth in the
Authorization. SWAN and GLBA NP
will submit final reports to NMFS
within 30 days after receiving comments
on the draft report. If SWAN or GLBA
NP receive no comments from NMFS on
the report, NMFS will consider the draft
report to be the final report. NPS will
also submit a comprehensive 5-year
report covering all activities conducted
under the incidental take regulations 90
days following expiration of these
regulations or, if new regulations are
sought, no later than 90 days prior to
expiration of the regulations.
Each 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 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; and
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.), NPS shall immediately
cease the specified activities and
immediately report the incident to the
Office of Protected Resources, NMFS
and the Alaska Regional Stranding
Coordinator. The report must include
the following information:
• Time, date, and location (latitude/
longitude) of the incident;
• Description and location of the
incident (including tide level 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;

Frm 00056

• 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).
NPS shall not resume its activities
until NMFS is able to review the
circumstances of the prohibited take.
NMFS will work with NPS to determine
what is necessary to minimize the
likelihood of further prohibited take and
ensure MMPA compliance. NPS may
not resume their activities until notified
by us via letter, email, or telephone.
In the event that NPS 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), NPS will immediately
report the incident to the Office of
Protected Resources, NMFS and the
Alaska Regional Stranding Coordinator.
The report must include the same
information identified in the paragraph
above. Activities may continue while
we review the circumstances of the
incident. We will work with NPS to
determine whether modifications in the
activities are appropriate.
In the event that NPS 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), NPS will report the incident to
the incident to the Office of Protected
Resources, NMFS and the Alaska
Regional Stranding Coordinator within
24 hours of the discovery. NPS
researchers will provide photographs or
video footage (if available) or other
documentation of the stranded animal
sighting to us. NPS can continue their
research activities.
Negligible Impact Analysis and
Determination
NMFS has defined negligible impact
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
(50 CFR 216.103). A negligible impact
finding is based on the lack of likely
adverse effects on annual rates of
recruitment or survival (i.e., populationlevel effects). An estimate of the number
of takes alone is not enough information
on which to base an impact
determination. In addition to
considering estimates of the number of
E:\FR\FM\13DEP1.SGM
13DEP1
amozie on DSK3GDR082PROD with PROPOSALS1
64092
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
marine mammals that might be ‘‘taken’’
through harassment, NMFS considers
other factors, such as the likely nature
of any responses (e.g., intensity,
duration), the context of any responses
(e.g., critical reproductive time or
location, migration), as well as effects
on habitat, and the likely effectiveness
of the mitigation. We also assess the
number, intensity, and context of
estimated takes by evaluating this
information relative to population
status. Consistent with the 1989
preamble for NMFS’s implementing
regulations (54 FR 40338; September 29,
1989), the impacts from other past and
ongoing anthropogenic activities are
incorporated into this analysis via their
impacts on the environmental baseline
(e.g., as reflected in the regulatory status
of the species, population size and
growth rate where known, ongoing
sources of human-caused mortality, or
ambient noise levels).
During these activities, harbor seals
and Steller sea lions may exhibit
behavioral modifications, including
temporarily vacating the area during the
proposed research and monitoring
activities to avoid human and vessel
disturbance. However, due to the
project’s minimal levels of visual and
acoustic disturbance (Level B
harassment only), NMFS does not
expect NPS’s specified activities to
cause long-term behavioral disturbance,
abandonment of the haulout area,
injury, serious injury, or mortality. In
addition, while a portion of these
proposed activities would take place in
areas of significance for marine mammal
feeding, resting, breeding, or pupping,
there would be no adverse impacts on
marine mammal habitat as discussed
above. Due to the nature, degree, and
context of the behavioral harassment
anticipated, we do not expect the
activities to impact annual rates of
recruitment or survival.
NMFS does not expect pinnipeds to
permanently abandon any area surveyed
by NPS researchers, as is evidenced by
continued presence of pinnipeds at the
GLBA NP sites during annual gull and
climate monitoring. NMFS anticipates
that impacts to hauled-out harbor seals
and Steller sea lions during NPS’
research and monitoring activities
would be behavioral harassment of
limited duration (i.e., up to two hours
per site visit) and limited intensity (i.e.,
temporary flushing at most).
In summary and as described above,
the following factors primarily support
our preliminary determination that the
impacts resulting from this activity are
not expected to adversely affect the
species or stock through effects on
annual rates of recruitment or survival:
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
• No mortality is anticipated or
authorized;
• The takes from Level B harassment
would be due to potential behavioral
disturbance;
• 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;
• The proposed activities would
partially take place in areas of
significance for marine mammal
feeding, resting, breeding, or pupping
but due to their nature and duration
would not adversely impact marine
mammal habitat or deny pinnipeds
access to this habitat because of the
large availability of alternate haulouts
and short-duration of disturbance;
• Anecdotal observations and results
from previous monitoring reports show
that the pinnipeds returned to the
various sites and did not permanently
abandon haulout sites after NPS
conducted their research activities; and
• Harbor seals and Steller sea lions
may flush into the water despite
researchers best efforts to keep calm and
quiet around these pinnipeds; however,
injury or mortality has never been
documented and is not anticipated from
flushing events. GLBA NP researchers
would approach study sites slowly to
provide enough time for any marine
mammals present to slowly enter the
water without panic. SWAN researchers
would attempt to conduct their surveys
at a distance which would not result in
pinniped disturbance.
Based on the analysis contained
herein of the likely effects of the
specified activity on marine mammals
and their habitat, and taking into
consideration the implementation of the
proposed monitoring and mitigation
measures, NMFS preliminarily finds
that the total marine mammal take from
the proposed activity will have a
negligible impact on all affected marine
mammal species or stocks.
Small Numbers Analysis
As noted above, only small numbers
of incidental take may be authorized
under Section 101(a)(5)(D) of the MMPA
for specified activities other than
military readiness activities. The MMPA
does not define small numbers and so,
in practice, where estimated numbers
are available, NMFS compares the
number of individuals proposed to be
taken to the most appropriate estimation
of abundance of the relevant species or
stock in our determination of whether
an authorization is limited to small
numbers of marine mammals.
Additionally, other qualitative factors
may be considered in the analysis, such
PO 00000
Frm 00057
Fmt 4702
Sfmt 4702
as the temporal or spatial scale of the
activities.
As mentioned previously, NMFS
estimates that NPS’ research activities,
including gull monitoring, climate
monitoring, and marine animal surveys,
could potentially affect, by Level B
harassment only, two species of marine
mammal under our jurisdiction. For
harbor seals, this annual take estimate is
small relative to the three impacted
stocks, ranging from 0.3 to 3.7 percent
(See Table 1, Table 5, and Table 6). For
Steller sea lions, this annual take
estimate is small (200 sea lions) relative
to the western stock (0.4 percent) or
eastern stock (0.5 percent). In addition
to this, there is a high probability in the
GLBA NP activities that repetitive takes
of the same animal may occur which
reduces the percentage of population
impacted even further.
Based on the analysis contained
herein of the proposed activity
(including the proposed mitigation and
monitoring measures) and the
anticipated take of marine mammals,
NMFS preliminarily finds that small
numbers of marine mammals will be
taken relative to the population size of
the affected species or stocks.
Impact on Availability of Affected
Species for Taking for Subsistence Uses
There are no relevant subsistence uses
of marine mammals implicated by the
specified activities in GLBA NP, KATM,
or KEFJ. Subsistence harvest is
prohibited in these national parks and
the nature of the activities means they
should not affect any harvest occurring
in nearby waters. There is possible
pinniped harvest in KBAY, but the
timing of the survey is removed from
the peak seasons of harvest.
Additionally, the disturbance to
pinnipeds caused by NPS’s activities is
limited to non-lethal take by Level B
harassment and is temporary and short
in duration. Therefore, we have
preliminarily determined that the total
taking of affected species or stocks
would not have an unmitigable adverse
impact on the availability of such
species or stocks for taking for
subsistence purposes.
Endangered Species Act (ESA)
Section 7(a)(2) of the Endangered
Species Act of 1973 (ESA: 16 U.S.C.
1531 et seq.) requires that each Federal
agency insure that any action it
authorizes, funds, or carries out is not
likely to jeopardize the continued
existence of any endangered or
threatened species or result in the
destruction or adverse modification of
designated critical habitat. To ensure
ESA compliance for the issuance of
E:\FR\FM\13DEP1.SGM
13DEP1
Federal Register / Vol. 83, No. 239 / Thursday, December 13, 2018 / Proposed Rules
incidental take regulations and
subsequent LOAs, NMFS consults
internally, in this case with the Alaska
Regional Office, whenever we propose
to authorize take for endangered or
threatened species.
NMFS is proposing to authorize take
of western DPS Steller sea lions, which
are listed under the ESA.
NMFS’s Office of Protected Resources
has requested initiation of Section 7
consultation with NMFS’s Alaska
Regional Office for the issuance of this
LOA. NMFS will conclude the ESA
consultation prior to reaching a
determination regarding the proposed
issuance of the authorization.

Adaptive Management
The regulations governing the take of
marine mammals incidental to NPS
research and monitoring activities in
GLBA NP and SWAN region would
contain an adaptive management
component.
The reporting requirements associated
with this proposed rule are designed to
provide NMFS with monitoring data
from the previous year to allow
consideration of whether any changes
are appropriate. The use of adaptive
management allows NMFS to consider
new information from different sources
to determine (with input from NPS
regarding practicability) on an annual or
biennial basis if mitigation or
monitoring measures should be
modified (including additions or
deletions). Mitigation measures could be
modified if new data suggests that such
modifications would have a reasonable
likelihood of reducing adverse effects to
marine mammals and if the measures
are practicable.
NPS’s monitoring program (see
‘‘Proposed Monitoring and Reporting’’)
would be managed adaptively. Changes
to the proposed monitoring program
may be adopted if they are reasonably
likely to better accomplish the MMPA
monitoring goals described previously
or may better answer the specific
questions associated with NPS’s
monitoring plan.
The following are some of the
possible sources of applicable data to be
considered through the adaptive
management process: (1) Results from
monitoring reports, as required by
MMPA authorizations; (2) results from
general marine mammal and sound
research; and (3) any information which
reveals that marine mammals may have
been taken in a manner, extent, or
number not authorized by these
regulations or subsequent LOAs.

For reasons set forth in the preamble,
50 CFR part 217 is proposed to be

PART 217—REGULATIONS
GOVERNING THE TAKING AND
IMPORTING OF MARINE MAMMALS
1. The authority citation for part 217
continues to read as follows:

Authority: 16 U.S.C. 1361 et seq.
2. Add subpart C to part 217 to read
as follows:
Pursuant to the procedures
established to implement Executive
Order 12866, the Office of Management
and Budget has determined that this
proposed rule is not significant.
Pursuant to section 605(b) of the
Regulatory Flexibility Act (RFA), the
Chief Counsel for Regulation of the
Department of Commerce has certified
to the Chief Counsel for Advocacy of the
Small Business Administration that this
proposed rule, if adopted, would not
have a significant economic impact on
a substantial number of small entities.
NPS is the sole entity that would be
subject to the requirements in these
proposed regulations, and the NPS is
not a small governmental jurisdiction,
small organization, or small business, as
defined by the RFA. Because of this
certification, a regulatory flexibility
analysis is not required and none has
been prepared.
Notwithstanding any other provision
of law, no person is required to respond
to nor shall a person be subject to a
penalty for failure to comply with a
collection of information subject to the
requirements of the Paperwork
Reduction Act (PRA) unless that
collection of information displays a
currently valid OMB control number.
However, this proposed rule does not
contain a collection-of-information
requirement subject to the provisions of
the Paperwork Reduction Act (PRA)
because the applicant is a Federal
agency, and the information is not ‘‘uses

Mitigation requirements.
When conducting the activities
identified in § 217.20(a), the mitigation
measures contained in any LOA issued
under § 216.106 of this chapter and
§ 217.24 must be implemented. These
mitigation measures shall include but
are not limited to:
(a) General conditions: (1) A copy of
any issued LOA must be in the
possession of NPS, its designees, and
additional survey crew personnel
operating under the authority of the
issued LOA.
(2) Before all surveys, the lead NPS
biologist must instruct additional survey
crew on appropriate conduct when in
the vicinity of hauled-out marine
mammals. This training must brief
survey personnel on marine mammals
(inclusive of identification as needed,
e.g., neonates).
(3) If humpback whales, killer whales,
or beluga whales are observed, NPS
must avoid operation of a motor vessel
within 1⁄4 nautical mile of a whale. If
accidentally positioned within 1⁄4
nautical mile of a whale, NPS must slow

pinnipeds, such that any potential
follow-up research can be conducted by
the appropriate personnel; marked or
tag-bearing pinnipeds or carcasses,
allowing transmittal of the information
to appropriate agencies; and any rare or
unusual species of marine mammal for
agency follow-up. The observer will
report that information to NMFS’s
Alaska Fisheries Science Center and/or
the Alaska Department of Fish and
Game Marine Mammal Program.
(b) SWAN Marine Bird and Mammal
Surveying. (1) Species counts and
numbers of type 3, flushing,
disturbances;
(2) Information on the weather,

follow-up research can be conducted by
the appropriate personnel; marked or
tag-bearing pinnipeds or carcasses,
allowing transmittal of the information
to appropriate agencies; and any rare or
unusual species of marine mammal for
agency follow-up. The observer will
report that information to NMFS’s
Alaska Fisheries Science Center and/or
the Alaska Department of Fish and
Game Marine Mammal Program.
(c) NPS must submit separate annual
draft reports for GLBA NP and SWAN
on all monitoring conducted within
ninety calendar days of the completion
of annual research and monitoring
activities. Final reports for both GLBA

the Authorization and full
documentation of methods, results, and
interpretation pertaining to all
monitoring.
(d) NPS must submit a comprehensive
5-year report covering all activities
conducted under the incidental take
regulations at least 90 days prior to
expiration of these regulations if new
regulations are sought or 90 days after
expiration of regulations.
(e) Reporting of injured or dead
marine mammals. (1) In the
unanticipated event that the activity
defined in § 219.20(a) clearly causes the
take of a marine mammal in a
prohibited manner such as an injury
(Level A harassment), serious injury, or
mortality, NPS must immediately cease
the specified activities and report the
incident to the Office of Protected
Resources, NMFS, and the Alaska
Regional Stranding Coordinator, NMFS.
The report must include the following
information:
(i) Time and date of the incident;
(ii) Description of the incident;
(iii) Environmental conditions (e.g.,
wind speed and direction, Beaufort sea
state, cloud cover, and visibility);
(iv) Description of all marine mammal
observations and active sound source
use in the 24 hours preceding the
incident;
(v) Species identification or
description of the animal(s) involved;
(vi) Fate of the animal(s); and
(vii) Photographs or video footage of
the animal(s).
(2) Activities must not resume until
NMFS is able to review the
circumstances of the prohibited take.
NMFS will work with NPS to determine
what measures are necessary to
minimize the likelihood of further
prohibited take and ensure MMPA
compliance. NPS must not resume their
activities until notified by NMFS.
(3) In the event that NPS discovers an
injured or dead marine mammal, and
the lead observer determines that the
cause of the injury or death is unknown
and the death is relatively recent (e.g.,
in less than a moderate state of
decomposition), NPS must immediately
report the incident to the Office of
Protected Resources, NMFS, and the
Alaska Stranding Coordinator, NMFS.
The report must include the same
information identified in § 217.25(e)(1).
Activities may continue while NMFS
reviews the circumstances of the
incident. NMFS will work with NPS to
determine whether additional
mitigation measures or modifications to
the activities are appropriate.
(4) In the event that NPS discovers an
injured or dead marine mammal and
determines that the injury or death is
VerDate Sep<11>2014
16:36 Dec 12, 2018
Jkt 247001
not associated with or related to the
activities defined in § 217.20(a) (e.g.,
previously wounded animal, carcass
with moderate to advanced
decomposition, scavenger damage), NPS
must report the incident to OPR and the
Alaska Stranding Coordinator, NMFS,
within 24 hours of the discovery. NPS
must provide photographs or video
footage or other documentation of the
stranded animal sighting to NMFS. NPS
can continue their research activities.
(5) Pursuant to paragraphs
§ 217.25(e)(2) through (4), NPS may use
discretion in determining what injuries
(i.e., nature and severity) are
appropriate for reporting. At minimum,
NPS must report those injuries
considered to be serious (i.e., will likely
result in death) or that are likely caused
by human interaction (e.g.,
entanglement, gunshot). Also pursuant
to paragraphs § 217.25(e)(3) and (4) of
this section, NPS may use discretion in
determining the appropriate vantage
point for obtaining photographs of
injured/dead marine mammals.
§ 217.26
Letters of Authorization.
(a) To incidentally take marine
mammals pursuant to these regulations,
NPS must apply for and obtain an LOA.
(b) An LOA, unless suspended or
revoked, may be effective for a period of
time not to exceed the expiration date
of these regulations.
(c) If an LOA expires prior to the
expiration date of these regulations,
NPS may apply for and obtain a renewal
of the LOA.
(d) In the event of projected changes
to the activity or to mitigation and
monitoring measures required by an
LOA, NPS must apply for and obtain a
modification of the LOA as described in
§ 217.27.
(e) The LOA shall set forth:
(1) Permissible methods of incidental
taking;
(2) Means of effecting the least
practicable adverse impact (i.e.,
mitigation) on the species, its habitat,
and on the availability of the species for
subsistence uses; and
(3) Requirements for monitoring and
reporting.
(f) Issuance of the LOA shall be based
on a determination that the level of
taking will be consistent with the
findings made for the total taking
allowable under these regulations.
(g) Notice of issuance or denial of an
LOA shall be published in the Federal
Register within 30 days of a
determination.

notice of proposed LOA in the Federal
Register, including the associated
analysis of the change, and solicit
public comment before issuing the LOA.
(c) An LOA issued under §§ 216.106
of this chapter and 217.26 for the
activity identified in § 217.20(a) may be
modified by NMFS under the following
circumstances:
(1) Adaptive Management—NMFS
may modify (including augment) the
existing mitigation, monitoring, or
reporting measures (after consulting
with NPS regarding the practicability of
the modifications) if doing so creates a
reasonable likelihood of more
effectively accomplishing the goals of
the mitigation and monitoring set forth
in the preamble for these regulations.
(i) Possible sources of data that could
contribute to the decision to modify the
mitigation, monitoring, or reporting
measures in an LOA:
(A) Results from NPS’s monitoring
from the previous year(s).

Taking and Importing Marine Mammals; Taking Marine Mammals
Incidental to National Park Service's Research and Monitoring
Activities in Southern Alaska National Parks
AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA), Commerce.
ACTION: Proposed rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: NMFS has received a request from the National Park Service
(NPS) for authorization to take marine mammals incidental to research
and monitoring activities in southern Alaska over the course of five
years (2019-2024). These activities include glaucous-winged gull and
climate monitoring activities in Glacier Bay National Park (GLBA NP),
Alaska and marine bird and mammal survey activities conducted by the
Southwest Alaska Inventory and Monitoring Network (SWAN) in national
parks and adjacent lands. As required by the Marine Mammal Protection
Act (MMPA), NMFS is proposing regulations to govern that take and
requests comments on the proposed regulations.

National Environmental Policy Act (NEPA)
To comply with the National Environmental Policy Act of 1969 (NEPA;
42 U.S.C. 4321 et seq.) and NOAA Administrative Order (NAO) 216-6A,
NMFS must review our proposed action (i.e., the issuance of an
incidental take authorization) with respect to potential impacts on the
human environment.
This action is consistent with categories of activities identified
in CE B4 of the Companion Manual for NOAA Administrative Order 216-6A,
which do not individually or cumulatively have the potential for
significant impacts on the quality of the human environment and for
which we have not identified any extraordinary circumstances that would
preclude this categorical exclusion. Accordingly, NMFS has
preliminarily determined that the issuance of the proposed rule and
subsequent Letters of Authorization qualifies to be categorically
excluded from further NEPA review. We will review all comments
submitted in response to this notice prior to concluding our NEPA
process or making a final decision on the request.
Purpose and Need for Regulatory Action
This proposed rule, to be issued under the authority of the Marine
Mammal Protection Act (MMPA) (16 U.S.C. 1361 et seq.), would establish
a framework for authorizing the take of marine mammals incidental to
NPS's gull and climate monitoring activities within GLBA NP and marine
bird and mammal surveys in the SWAN region. Researchers conducting
these surveys may cause behavioral disturbance (Level B harassment) of
harbor seals and Steller sea lions.
We received an application from NPS requesting five-year
regulations and authorization to take harbor seals and Steller sea
lions. Take would occur by Level B harassment incidental to research
and monitoring activities due to behavioral disturbance of pinnipeds.
The regulations would be valid from 2019 to 2024. Please see
``Background'' below for definitions of harassment.
Legal Authority for the Proposed Action
Section 101(a)(5)(A) of the MMPA (16 U.S.C. 1371(a)(5)(A)) directs
the Secretary of Commerce to allow, upon request, the incidental, but
not intentional taking of small numbers of
[[Page 64079]]
marine mammals by U.S. citizens who engage in a specified activity
(other than commercial fishing) within a specified geographical region
for up to five years if, after notice and public comment, the agency
makes certain findings and issues regulations that set forth
permissible methods of taking pursuant to that activity, as well as
monitoring and reporting requirements. Section 101(a)(5)(A) of the MMPA
and the implementing regulations at 50 CFR part 216, subpart I provide
the legal basis for issuing this proposed rule containing five-year
regulations, and for any subsequent Letters of Authorization. As
directed by this legal authority, this proposed rule contains
mitigation, monitoring, and reporting requirements.
Summary of Major Provisions Within the Proposed Rule
The following provides a summary of some of the major provisions
within the proposed rulemaking for NPS's research and monitoring
activities in southern Alaska. We have preliminarily determined that
NPS's adherence to the proposed mitigation, monitoring, and reporting
measures listed below would achieve the least practicable adverse
impact on the affected marine mammals. They include:
Measures to minimize the number and intensity of
incidental takes during monitoring activities and to minimize the
duration of disturbances.
Measures designed to eliminate startling reactions.
Eliminating or altering research activities on GLBA NP
beaches when pups are present, and setting limits on the frequency and
duration of events during pupping season.
Background
Paragraphs 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1371
(a)(5)(A) and (D)) direct the Secretary of Commerce 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 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.
An authorization for incidental takings shall be granted if NMFS
finds that the taking will have a negligible impact on the species or
stock(s); will not have an unmitigable adverse impact on the
availability of the species or stock(s) for subsistence uses (where
relevant); and if the permissible methods of taking and requirements
pertaining to the mitigation, 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. NMFS has defined ``unmitigable adverse
impact'' in 50 CFR 216.103 as an impact resulting from the specified
activity:
That is likely to reduce the availability of the species
to a level insufficient for a harvest to meet subsistence needs by:
[cir] Causing the marine mammals to abandon or avoid hunting areas;
[cir] Directly displacing subsistence users; or
[cir] Placing physical barriers between the marine mammals and the
subsistence hunters; and
That cannot be sufficiently mitigated by other measures to
increase the availability of marine mammals to allow subsistence needs
to be met.
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 February 6, 2018, we received an adequate and complete request
from NPS for authorization to take marine mammals incidental to gull
and climate monitoring activities in GLBA NP. On February 22, 2018 (83
FR 7699), we published a notice of receipt of NPS's application in the
Federal Register, requesting comments and information related to the
request for 30 days. We did not receive any comments. NPS provided a
revised application incorporating minor revisions on April 23, 2018.
Subsequently, NPS has identified additional research and monitoring
projects in southern Alaska (SWAN region) with similar sources of
marine mammal disturbance and potential effects. On October 29, 2018,
NMFS received an adequate and complete revised application including
these additional research and monitoring activities. These additional
activities were determined to be similar in scope and impact to the
original proposed activities, and NMFS determined that publication of a
revised notice of receipt was not necessary for the updated
application.
Prior to this request for incidental take regulations and
subsequent Letters of Authorization (LOA), we issued five consecutive
incidental harassment authorizations (IHA) to NPS for incidental take
associated with the GLBA NP ongoing gull and climate monitoring
activities. NPS was first issued an IHA, valid for a period of one
year, effective on September 18, 2014 (79 FR 56065), and was
subsequently issued one-year IHAs for incidental take associated with
the same activities, effective on March 24, 2015 (80 FR 28229), June 1,
2016 (77 FR 24471), May 20, 2017 (82 FR 24681), and February 15, 2018
(83 FR 6842). NPS has abided by all of NMFS's mitigation and monitoring
requirements in previous activities for which take was authorized.
Description of the Specified Activity
Glacier Bay
NPS is proposing to conduct two research projects within the GLBA
NP in southeast Alaska: (1) Glaucous-winged gull monitoring, and (2)
the maintenance of a weather station operation for long-term climate
monitoring. NPS would conduct ground and vessel surveys at six study
sites within GLBA NP for gull monitoring: South Marble Island, Boulder
Island, Lone Island, Geikie Rock, Flapjack Island, and Tlingit Point
Islet. These sites will be accessed up to five times per year. In
addition, NPS is requesting permission to access Lone Island an
additional three times per year for weather station maintenance and
operation bringing the total number of site visits to Lone Island to
eight. This includes adding one additional trip for any emergency
repairs that may be needed. Researchers accessing the islands for gull
monitoring and weather station operation may cause behavioral
disturbance (Level B harassment) of harbor seals. NPS expects that the
disturbance to harbor seals from both projects will be limited to Level
B harassment.
The purpose for the above-mentioned research activities are as
follows. Gull monitoring studies are mandated by a Record of Decision
of a Legislative Environmental Impact Statement (LEIS) (NPS 2010) which
states that NPS must initiate a monitoring program for glaucous-winged
gulls (Larus glaucescens) to inform future native egg harvest by the
Hoonah Tlingit in Glacier Bay, Alaska. Installation of a new weather
station on Lone Island was conducted by the NPS in the spring of
[[Page 64080]]
2018 as one of several installations intended to fill coverage gaps
among existing weather stations in GLBA NP (NPS 2015a). In order to
properly maintain the newly installed weather station, researchers must
access the Lone Island weather station site at least twice a year for
annual maintenance and repairs.
SWAN
NPS is applying for an LOA to conduct the SWAN marine bird and
mammal multi-species nearshore surveys along the coastlines of Katmai
National Park and Preserve (KATM), Kenai Fjords National Park (KEFJ),
and in Kachemak Bay (KBAY) in support of long-term monitoring programs
in these regions of southwest Alaska. Occasional disturbance of Steller
sea lions and harbor seals may occur during surveys. Steller sea lion
and harbor seal habitat coincides with surveyed nearshore transects.
Please see NPS's application for established transect locations for
KATM and KEFJ and proposed transect locations for KBAY. NPS expects
that the disturbance will be limited to Level B harassment and will not
result in serious injury or death. SWAN also seeks to foster further
collaborations with NOAA and share monitoring data in the future.
Dates and Duration
Glacier Bay
The specified activity would be valid during the five-year period
of validity for these proposed regulations (March 1, 2019 through
February 29, 2024). Ground and vessel surveys for nesting gulls will be
conducted from May through September on bird nesting islands in GLBA NP
(see Figure 1 of LOA Application) and other suspected gull colonies.
There will be 1-3 ground visits and 1-2 vessel surveys at each site for
a maximum of five visits per site. Duration of surveys will be 30
minutes to two hours each.
Maintenance of the Lone Island weather station may begin March 1,
2019. To avoid the gull-nesting period, all maintenance and emergency
repair-related site visits to this location are planned to occur
between March and April during the first year, and October to April in
following years, but visits could occur outside of this time period if
necessary with authorization from the park Superintendent to ensure
protection of park resources and values. Possible unanticipated station
failures requiring emergency repair will require up to eight hours. Two
planned maintenance visits will require approximately two hours per
visit.
SWAN
NPS's activities in the SWAN region would be valid during the five
year period of validity for these proposed regulations (March 1, 2019
through February 29, 2024). Standardized surveys of marine birds are
proposed in KATM and KEFJ between late June and early July and are
generally conducted by two survey crews on independent small vessels
(5-8 m length) traveling at speeds of 8-12 knots along randomly
selected sections of coastline that represent independent transects.
The two crews operate independently and do not survey the same
transects. Winter surveys are conducted in March and consist of the
same set of transects surveyed in the summer months. Only one region,
either KATM or KEFJ, per winter season is surveyed. Regions surveyed in
the winter are on a rotation. Similar annual surveys are proposed in
KBAY, with summer surveys occurring in June or July and no winter
survey proposed. The survey of each area takes 3-4 days to complete
with both crews operating.
Specified Geographical Region
Glacier Bay
The proposed study sites would occur in the vicinity of the
following locations: South Marble, Boulder, Lone, and Flapjack Islands,
Tlinglit Point Islet, and Geikie Rock in GLBA NP in southeast Alaska
(see Figure 1 of LOA application). Each of these study sites are
located on the eastern side of the park situated near Geikie Inlet and
all provide harbor seal habitat throughout the year, however the
highest presence of seals occurs during the breeding and molting season
(May to October) (Lewis et al., 2017). On Boulder and Flapjack islands,
the proposed gull monitoring study sites are located on the north side
whereas harbor seal haulouts are positioned on the south (Lewis et al.,
2017). Also, on Lone Island, harbor seals are sited near tidal rocks
off the northeast tip of the island (ADEC, 2014), whereas on Geikie
Rock they are known to be found throughout the entire site due to its
small size (Lewis 2017). NPS will also conduct studies at South Marble
Island and Tlingit Point Islet; however, there are no reported harbor
seal haulout sites at those locations. South Marble Island is regularly
occupied by hauled out Steller sea lions, but GLBA NP researchers have
been able to access the island previously while maintaining 100 m
minimum distance from the Steller sea lions and avoiding disturbance.
SWAN
The proposed surveys will occur at two national parks, KATM and
KEFJ, as well as the nearby KBAY, in southwest AK. Detailed maps of the
survey transects are available in the NPS's LOA application. Transects
are conducted 100 or 150 m from shore and have a total width of
approximately 200 to 300 m centered on the vessel.
Detailed Description of Activities
Glacier Bay's Glaucous-Winged Gull Monitoring
Gull monitoring will be conducted using a combination of ground and
vessel surveys by landing at specific access points on the islands. NPS
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 during the period of May through
September.
Ground-based surveys for gull monitoring will involve two trained
observers conducting complete nest counts of the gull colonies. The
survey will encompass all portions of the gull colony accessible to
humans and thus represent a census of the harvestable nests. GPS
locations of nests and associated vegetation along with the number of
live and predated eggs will be collected during at least one visit to
obtain precise nest locations to characterize nesting habitat. On
subsequent surveys, nest counts will be tallied on paper so observers
can move through the colony more quickly and minimize disturbance.
Ground surveys will be discontinued after the first hatched chick is
detected to minimize disturbance and mortalities of gulls. During
ground surveys, observers will also record other bird and marine mammal
species in proximity to colonies.
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 (kn) (4.6 miles per hour (mph)). Ground surveys
generally last 30 minutes (min) to two hours (hrs) each depending on
the size of the island and the number of nesting gulls. During ground
surveys, Level B harassment of harbor seals can occur from either
acoustic disturbance from motorboat sounds or visual disturbance from
the presence of observers. Past monitoring reports show that most takes
(flushes or movements greater than one meter) from ground surveys
occurred as vessels approached a study site to perform a survey. Takes
usually occurred while
[[Page 64081]]
the vessel was 50-100 meters from the island (NPS 2015b; NPS 2016).
Vessel-based surveys for gull monitoring will be conducted from the
deck of a motorized vessel (10 to 12 meters) and will be used to count
the number of adult and fledgling gulls that are visible from the water
(Zador, 2001; Arimitsu et al., 2007). Vessel surveys provide a more
reliable estimate of the numbers of gulls in the colony than ground
surveys because NPS can count nesting birds in areas that are
inaccessible by foot and because the birds do not flush from the
researchers' presence. GLBA NP would conduct these surveys by circling
the islands at approximately 100 m from shore while counting the number
of adult and chick gulls as well as other bird and mammal species
present. Surveys can be from 30 min to two hrs in duration. During
vessel surveys, Level B harassment of harbor seals can occur from
either acoustic disturbance from motorboat sounds or visual disturbance
from the presence of observers. Past monitoring reports show that most
takes (flushes or movements greater than one meter) from vessel surveys
occurred as the vessel was 100 m from the island (NPS 2015b; NPS 2016).
Glacier Bay's Climate Monitoring (Weather Station Maintenance)
To conduct climate monitoring and weather station maintenance
activities, Lone Island will be accessed by a 10-20 m motor vessel.
Materials will be carried by hand to the weather station location.
Station configuration and maintenance is typical of Remote Automated
Weather Stations (RAWS) operated by land management agencies for
weather and climate monitoring, fire weather observation, and other
uses. The weather station consists of an 8-ft monopole and associated
guy lines. In addition, there is a fuel cell and sealed 12V battery
housed in a watertight enclosure that provides power to the station.
Standard meteorological sensors for measuring precipitation, wind,
temperature, solar radiation, and snow depth are used. Data is housed
in internal memory and communicated via satellite telemetry to the
Wildland Fire Management Institute where it is relayed to a variety of
repositories such as the Western Regional Climate Center in near real-
time. It is possible that the weather station can be accessed in a
fashion that will not disturb hauled out harbor seals. However NPS is
requesting authorization to ensure its ability to perform yearly
maintenance of the weather station.
SWAN Marine Bird and Marine Mammal Surveys
SWAN standardized surveys of marine birds are conducted in KATM and
KEFJ between late June and early July and are generally conducted from
small vessels (5-8 m length) traveling at speeds of 8-12 knots along
randomly selected sections of coastline that represent independent
transects. SWAN is also proposing similar surveys be implemented in
KBAY in cooperation with USGS and Gulf Watch Alaska. The survey design
consists of a series of transects along shorelines such that a minimum
of 20 percent of an NPS park shoreline is surveyed. Transects are
systematically selected beginning at a random starting point from the
pool of contiguous 2.5-5 km transects that are adjacent to the mainland
or islands. The transect width is 200-300 m, depending on the elevation
of the observer platform, and the survey boat represents the midpoint.
There are two survey teams, and each transect is surveyed by one team
of three. The boat operator generally surveys the 100-150 m offshore
area of the transect, while a second observer surveys the 100-150 m
nearshore area. The third team member enters the observations into a
laptop running software specifically designed for this type of
surveying, and the third team member can assist with observations when
needed. All marine birds and mammals within the 200-300 m transect
swath are identified and counted. Detailed descriptions of methods and
procedures can be found in the Marine Bird and Mammal Survey SOP
(Bodkin 2011).
Description of Marine Mammals in the Area of the Specified Activity
Sections 3 and 4 of the LOA application summarize available
information regarding status and trends, distribution and habitat
preferences, and behavior and life history, of the potentially affected
species. Additional information regarding population trends and threats
may be found in NMFS's Stock Assessment Reports (SAR; https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-stock-assessments) and more general information about these species
(e.g., physical and behavioral descriptions) may be found on NMFS's
website (https://www.fisheries.noaa.gov/find-species).
Table 1 lists all species with expected potential for occurrence
within the survey areas and summarizes information related to the
population or stock, including regulatory status under the MMPA and
Endangered Species Act (ESA) and potential biological removal (PBR),
where known. For taxonomy, we follow the Committee on Taxonomy (2017).
PBR is defined by the MMPA as the maximum number of animals, not
including natural mortalities, that may be removed from a marine mammal
stock while allowing that stock to reach or maintain its optimum
sustainable population (as described in NMFS's SARs). While no
mortality is anticipated or authorized here, PBR and annual serious
injury and mortality from anthropogenic sources are included here as
gross indicators of the status of the species and other threats. Marine
mammal abundance estimates presented in this document represent the
total number of individuals that make up a given stock or the total
number estimated within a particular study or survey area. NMFS's stock
abundance estimates for most species represent the total estimate of
individuals within the geographic area, if known, that comprises that
stock. For some species, this geographic area may extend beyond U.S.
waters. All managed stocks in this region are assessed in NMFS's U.S.
Alaska SARs (Muto et al., 2018). All values presented in Table 1 are
the most recent available at the time of publication and are available
in the 2017 SARs (Muto et al., 2018).

All marine mammal species that could potentially occur in the
proposed survey areas are included in Table 1. While cetaceans,
including humpback, beluga, and killer whales, may be present in nearby
waters, NPS's activities are expected to result in harassment only for
hauled out pinnipeds. Therefore, cetaceans are not considered further
in this analysis. However, NPS does propose cetacean avoidance measures
as described in the ``Proposed Mitigation'' section below. Finally, sea
otters may be found throughout the proposed project area. However, sea
otters are managed by the U.S. Fish and Wildlife Service and are not
considered further in this document.
Steller Sea Lions
The Steller sea lion is the largest of the eared seals, ranging
along the North Pacific Rim from northern Japan to California, with
centers of abundance and distribution in the Gulf of Alaska and
Aleutian Islands. Steller sea lions were listed as threatened range-
wide under the ESA on November 26, 1990 (55 FR 49204). Subsequently,
NMFS published a final rule designating critical habitat for the
species as a 20 nautical mile buffer around all major haulouts and
rookeries, as well as associated terrestrial, air and aquatic zones,
and three large offshore foraging areas (58 FR 45269; August 27, 1993).
In 1997, NMFS reclassified Steller sea lions as two distinct population
segments (DPS), or stocks, based on genetic studies and other
information (62 FR 24345; May 5, 1997). Steller sea lion populations
that primarily occur west of 144[deg] W (Cape Suckling, Alaska)
comprise the western stock, while all others comprise the eastern
stock; however, there is regular movement of both stocks across this
boundary (Jemison et al., 2013). Upon this reclassification, the
western DPS, or stock, was listed as endangered while the eastern DPS,
or stock, remained as threatened (62 FR 24345; May 5, 1997) and in
November 2013, the eastern DPS was delisted (78 FR 66140).
Steller sea lions are not known to migrate, but individuals may
disperse widely outside the breeding season (late May to early July).
At sea, Steller sea lions are commonly found from nearshore habitats to
the continental shelf and slope. The western stock breeds on rookeries
in Alaska from Prince William Sound west through the Aleutian Islands.
Steller sea lions use 38 rookeries and hundreds of haulouts within
their range in western Alaska (Allen and Angliss 2013). The eastern
stock originates from rookeries east of Cape Suckling, Alaska, and can
be found between southeast Alaska and California.
SWAN
SWAN's activities all occur west of the 144[deg] W line that splits
the two Steller sea lion stocks, but there is some mixing across that
boundary. Steller sea lions impacted by NPS' research and monitoring
activities could belong to either stock, and it is not possible to
determine which stock a Steller sea lion belongs to by simple
observation. Both stocks of Steller sea lions are therefore considered
in this analysis.
SWAN surveys occur in areas with known Steller sea lion haulouts
and there are two rookeries in KEFJ (see application). KATM and KEFJ
shorelines are both within Steller sea lion critical habitat including
the aquatic zone (or buffer) that extends 37 kilometers (20 nautical
miles) seaward in all directions from each rookery and major haulout.
Critical habitat also includes three large offshore foraging areas: The
Shelikof Strait area, the Bogoslof area, and the Seguam Pass area (58
FR 45269) with only the Shelikof Strait area relevant to this action.
Steller sea lions are sometimes present in KBAY, but the area is not
critical habitat. Regulations prevent approach by vessel to within
three nautical miles of major rookeries (50 CFR 224.103).
Glacier Bay
The temporal and/or spatial occurrence of Steller sea lions is such
that take is not expected to occur in GLBA NP research sites and
researchers would not approach Steller sea lions. Steller sea lions
which occur in GLBA NP are generally found on South Marble Island (see
Figure 1 in the Application). No disturbance of Steller sea lions is
expected from GLBA NP activities, so their presence in the area is not
discussed beyond the information provided here.
A total of five Steller sea lions have been observed during the
2015, 2016, and 2017 GLBA NP gull survey seasons (climate monitoring
did not take place during these years) (NPS 2015b; NPS 2016; NPS 2017).
However, all Steller sea lions that were spotted were observed outside
the study area. Steller sea lions are present in GLBA NP, but are not
generally seen on the islands being researched. NPS has proposed
mitigation, including staying at least 100 m away from all Steller sea
lions (see Proposed Mitigation), which has been found to be sufficient
to avoid take by Level B harassment due to Steller sea lions' tolerance
of vessels and lack of response to humans from a distance.
Harbor Seals
Harbor seals are the most abundant marine mammal species found
within the action area and are present year-round. Harbor seals range
from Baja California north along the west coasts of Washington, Oregon,
California, British Columbia, and Southeast Alaska; west through the
Gulf of Alaska, Prince
[[Page 64083]]
William Sound, and the Aleutian Islands; and north in the Bering Sea to
Cape Newenham and the Pribilof Islands. The current statewide abundance
estimate for Alaskan harbor seals is 205,090 (Muto et al., 2017), based
on aerial survey data collected during 1998-2011. In 2010, harbor seals
in Alaska were partitioned into 12 separate stocks based largely on
genetic structure (Allen and Angliss, 2010). Harbor seals have declined
dramatically in some parts of their range over the past few decades,
while in other parts their numbers have increased or remained stable
over similar time periods.
Harbor seals haul out on rocks, reefs, beaches, and drifting
glacial ice (Allen and Angliss, 2014). They are non-migratory; their
local movements are associated with tides, weather, season, food
availability, and reproduction, as well as sex and age class (Allen and
Angliss, 2014; Boveng et al., 2012; Lowry et al., 2001; Swain et al.,
1996). Pupping in Alaska generally takes place in May and June; while
molting generally occurs from June to October.
Glacier Bay Stock/Icy Strait Stock
Harbor seals of Glacier Bay range from Cape Fairweather southeast
to Column Point, extending inland to Glacier Bay, Icy Strait, and from
Hanus Reef south to Tenakee Inlet (Muto et al., 2017). This is the only
stock that would be impacted by research and monitoring activities in
GLBA NP. The Glacier Bay/Icy Strait stock showed a negative population
trend from 1992 to 2008 in June and August for glacial (-7.7 percent/
year; -8.2 percent/year) and terrestrial sites (-12.4 percent/year,
August only) (Womble et al., 2010 as cited in Muto et al., 2017). Trend
estimates by Mathews and Pendleton (2006) were similarly negative for
both glacial and terrestrial sites. Prior to 1993, seal counts were up
to 1,347 in the East Arm of Glacier Bay; 2008 counts were fewer than
200 (Streveler, 1979; Molnia, 2007 as cited in Muto et al., 2017).
These observed declines in harbor seals resulted in new research
efforts which were initiated in 2004 and were aimed at trying to
further understand the biology and ecology of seals and possible
factors that may have contributed to the declines (e.g., Herreman et
al. 2009, Blundell et al. 2011, Hueffer et al. 2012, Womble and Gende
2013a, Womble et al. 2014), with an emphasis on possible factors that
may have contributed to the declines. The recent studies suggest that
(1) harbor seals in Glacier Bay are not significantly stressed due to
nutritional constraints (Blundell et al. 2011), (2) the clinical health
and disease status of seals within Glacier Bay is not different than
seals from stable or increasing populations (Hueffer et al. 2012), and
(3) disturbance by vessels does not appear to be a primary factor
driving the decline (Young 2009).
Long-term monitoring of harbor seals on glacial ice has occurred in
Glacier Bay since the 1970s (Mathews and Pendleton, 2006) and has shown
this area to support one of the largest breeding aggregations in Alaska
(Steveler, 1979; Calambokidis et al., 1987 as cited in Muto et al.,
2015). After a large scale retreat of the Muir Glacier (more than 7
km), in the East Arm of Glacier Bay, between 1973 and 1986 and the
subsequent grounding and cessation of calving in 1993, floating glacial
ice was greatly reduced as a haulout substrate for harbor seals and
ultimately resulted in the abandonment of upper Muir Inlet by harbor
seals (Calambokidis et al., 1987; Hall et al., 1995; Mathews, 1995 as
cited in Muto et al., 2017). The most recent long-term trend estimate
for harbor seals at terrestrial sites in Glacier Bay for the 22-year
period from 1992-2013 is -6.91 percent/year (SE = 0.40, 95% CI = -7.69,
-6.13) (Womble et al. 2015). This trend is less negative than previous
estimates stated in the paragraph above. In addition, from 2004-2013,
there was a 10-year trend estimate of 9.64 percent increase per year
(SE = 1.66, 95% CI = 6.40, 12.89) (Womble et al., 2015).
Results from satellite telemetry studies suggest that harbor seals
travel extensively beyond the boundaries of Glacier Bay during the
post-breeding season (September-April); however, harbor seals
demonstrated a high degree of inter-annual site fidelity (93 percent)
to Glacier Bay the following breeding season (Womble and Gende 2013b).
Spatial and temporal regulations, for vessels transiting in and near
harbor seal breeding areas, and operating regulations, for vessels
operating within those areas, are all aimed at reducing the impacts of
human visitation.
Harbor seals from the Glacier Bay/Icy Strait stock can be found
hauled out at four of the gull monitoring study sites (Table 2). Seal
counts from gull monitoring surveys likely represent a minimum estimate
due to difficulty observing marine mammals from a vessel. Counts from
gull monitoring surveys are conducted during high tide so fewer seals
may be present.

As alluded to, there can be greater numbers of seals on the survey
islands than what is detected by the NPS during the gull surveys.
Aerial survey maximum counts show that harbor seals sometimes haul out
in large numbers at all four locations (see Table 2 of the
application). However, harbor seals hauled out at Flapjack Island are
generally on the southern end whereas the gull colony is on the
northern end. Similarly, harbor seals on Boulder Island tend to haul
out on the southern end while the gull colony is located and can be
accessed on the northern end without causing disturbance of harbor
seals. Aerial survey counts for harbor seals are conducted during low
tide while ground and vessel surveys are conducted during high tide
which, along with greater visibility during aerial surveys, may also
contribute to the greater numbers of seals observed during the aerial
surveys because there is more land available to use as a haulout during
low tide.
[[Page 64084]]
Prince William Sound Stock
The Prince William Sound stock includes harbor seals both within
and adjacent to Prince William Sound proper from approximately Cape
Fairweather to Elizabeth Island, including the KEFJ survey area. Within
Prince William Sound proper, harbor seals declined in abundance by 63
percent between 1984 and 1997 (Frost et al. 1999). In Aialik Bay,
adjacent to Prince William Sound proper, there has been a decline in
pup production by 4.6 percent annually from 40 down to 32 pups born
from 1994 to 2009 (Hoover-Miller et al. 2011). The current (2007-2011)
estimate of the Prince William Sound population trend over a 5-year
period is +26 seals per year with a probability that the stock is
decreasing of 0.56. The presence of an increasing trend with a greater
than .5 probability of decreasing is due to skewness impacting
statistical estimates. This occurrence is discussed further in Muto et
al. (2018).
From 1992-1997, results from a satellite telemetry study showed
Prince William Sound harbor seals tended to remain in or near Prince
William Sound. Juvenile seals were occasionally found to range up to
300 to 500 km east and west into the Gulf of Alaska. In June and July,
when SWAN region surveys would occur, harbor seals tended to have their
smallest home range sizes, remaining nearer to their haulout than other
times of year (Lowry et al. 2001).
Cook Inlet/Shelikof Strait Stock
The Cook Inlet/Shelikof Strait stock includes harbor seals from
approximately Elizabeth Island to Unimak Island, as well as those
within Cook Inlet. Multiple harbor seal haulouts exist in KBAY and KATM
(London et al, 2015; Montgomery et al 2007). This stock of harbor seals
would be found in the KATM and KBAY survey areas of SWAN's activities.
A multi-year study of seasonal movements and abundance of harbor seals
in Cook Inlet was conducted between 2004 and 2007. This study involved
multiple aerial surveys throughout the year, and the data indicated a
stable population of harbor seals during the August molting period
(Boveng et al. 2011). Aerial surveys along the Alaska Peninsula present
greater logistical challenges and have therefore been conducted less
frequently. The current (2007-2011) estimate of the Cook Inlet/Shelikof
Strait population trend is +313 seals per year, with a probability of
0.38 that the stock is decreasing (Muto et al. 2018).
Potential Effects of the Specified Activity on Marine Mammals and Their
Habitat
This section includes a summary and discussion of the ways that
components of the specified activity may impact marine mammals and
their habitat. The ``Estimated Take'' section later in this document
includes a quantitative analysis of the number of individuals that are
expected to be taken by this activity. The ``Negligible Impact Analysis
and Determination'' section considers the content of this section, the
``Estimated Take'' section, and the ``Proposed Mitigation'' section, to
draw conclusions regarding the likely impacts of these activities on
the reproductive success or survivorship of individuals and how those
impacts on individuals are likely to impact marine mammal species or
stocks.
As previously stated, acoustic and visual stimuli generated by
motorboat operations and the presence of researchers have the potential
to cause Level B harassment of harbor seals hauled out on Boulder,
Lone, and Flapjack Islands, and Geikie Rock within GLBA NP. These same
stimuli generated by motorboat operations have the potential to cause
Level B harassment of harbor seals and Steller sea lions in KATM, KEFJ,
and KBAY. The following discussion provides further detail on the
potential visual and acoustic disturbances harbor seals and Steller sea
lions may encounter during the NPS' research and monitoring activities.
Human and Vessel Disturbance
Harbor seals and Steller sea lions may potentially experience
behavioral disruption rising to the level of harassment from monitoring
and research activities, which may include brief periods of airborne
noise from research vessels and visual disturbance due to the presence
and activity of the researchers both on vessels and on land during
ground surveys. Disturbed pinnipeds are likely to experience any or all
of these stimuli, and take may occur due to any in both isolation or
combined with one another. Due to the likely constant combination of
visual and acoustic stimuli resulting from the presence of vessels and
researchers, we do not consider impacts from acoustic and visual
stimuli separately.
Disturbances resulting from human activity can impact short- and
long-term pinniped haul out behavior (Renouf et al., 1981; Schneider
and Payne, 1983; Terhune and Almon, 1983; Allen et al., 1984; Stewart,
1984; Suryan and Harvey, 1999; and Kucey and Trites, 2006). Disturbance
includes a variety of effects, including subtle to conspicuous changes
in behavior, movement, and displacement. Reactions to sound, if any,
depend on the species, state of maturity, experience, current activity,
reproductive state, time of day, and many other factors (Richardson et
al., 1995; Wartzok et al., 2004; Southall et al., 2007; Weilgart,
2007). These behavioral reactions from marine mammals are often shown
as: changing durations of surfacing and dives, or moving direction and/
or speed; reduced/increased vocal activities; changing/cessation of
certain behavioral activities (such as socializing or feeding); visible
startle response or aggressive behavior; avoidance of areas; and/or
flight responses (e.g., pinnipeds flushing into the water from haulouts
or rookeries). If a marine mammal does react briefly to human presence
by changing its behavior or moving a small distance, the impacts of the
change are unlikely to be significant to the individual, let alone the
stock or population. However, if visual stimuli from human presence
displaces marine mammals from an important feeding or breeding area for
a prolonged period, impacts on individuals and populations could be
significant (e.g., Lusseau and Bejder, 2007; Weilgart, 2007).
Visual stimuli resulting from the presence of researchers and
vessels have the potential to result in take of harbor seals and
Steller sea lions on the research islands and coasts where these
pinnipeds haul out. The characteristics of these stimuli differ between
the GLBA NP and SWAN activities. In SWAN's activities, vessels move at
faster speeds (8-12 kn, vs 2-3 kn for GLBA NP) but are present for a
short time period transiting through an area and at a consistent
distance. Alternatively, while GLBA NP vessels are slower, they must
approach islands where pinnipeds may be hauled out, and both the vessel
and researchers will be present for a longer period of time. As noted,
harbor seals and Steller sea lions can exhibit a behavioral response
(e.g., including alert behavior, movement, vocalizing, or flushing) to
visual stimuli. NMFS does not consider the lesser reactions (e.g.,
alert behavior such as raising a head) to constitute harassment. Table
3 displays NMFS's three-point scale that categorizes pinniped
disturbance reactions by severity. Observed behavior falling within
categories two and three would be considered level B harassment. GLBA
NP is able to record these behaviors for all observed pinnipeds.
Because of the nature of their survey, SWAN
[[Page 64085]]
researchers will only be able to record the total number of observed
pinnipeds, and those which show an easily observable level 3 response
(flushing). With these numbers and previous monitoring information from
GLBA NP, NPS and NMFS should be able to estimate the total number of
takes by Level B harassment resulting from SWAN monitoring.

withdrawals at least twice the
animal's body length to longer
retreats over the beach or, if
already moving, a change of
direction of greater than 90
degrees. These movements would be
recorded and counted as a `take'.
3................. Flush.......... All retreats (flushes) to the
water. Flushing into the water
would be recorded and counted as a
`take'.
------------------------------------------------------------------------
Upon the occurrence of low-severity disturbance (i.e., the approach
of a vessel or person as opposed to an explosion or sonic boom),
pinnipeds typically exhibit a continuum of responses, beginning with
alert movements (e.g., raising the head), which may then escalate to
movement away from the stimulus and possible flushing into the water.
Flushed pinnipeds typically re-occupy the same haulout within minutes
to hours of a stimulus (Allen et al., 1984 (Johnson and Acevedo-
Gutierrez, 2007). As a result, a minimal number of animals may be taken
more than once during the proposed survey activities so the number of
takes likely represents exposures. In the case of GLBA NP, because
there will be no more than five annual visits to three gull study sites
and no more than eight annual visits to one other survey site, it is
expected that individual harbor seals at Boulder Island, Flapjack
Island, and Geike Rock will be disturbed no more than five times per
year and no more than eight times per year on Lone Island. For SWAN's
activities, KATM, KEFJ, and KBAY are each visited during the summer.
There is a winter survey conducted each year at either KATM or KEFJ.
Therefore individual harbor seals and Stellar sea lions at these
locations will be disturbed no more than two times per year.
Numerous studies have shown that human activity can flush pinnipeds
off haulout sites and beaches (Kenyon, 1972; Allen et al., 1984;
Calambokidis et al., 1991; Suryan and Harvey, 1999; and Mortenson et
al., 2000, Mathews, 2000). In 1997, Henry and Hammill (2001) conducted
a study to measure the impacts of small boats (i.e., kayaks, canoes,
motorboats and sailboats) on harbor seal haul out behavior in
M[eacute]tis Bay, Quebec, Canada. During that study, the authors noted
that the most frequent disturbances (n=73) were caused by lower speed,
lingering kayaks and canoes (33.3 percent) as opposed to motorboats
(27.8 percent) conducting high speed passes. The seals flight reactions
could be linked to a surprise factor by kayaks-canoes, which approach
slowly, quietly and low on water making them look like predators.
However, the authors note that once the animals were disturbed, there
did not appear to be any significant lingering effect on the recovery
of numbers to their pre-disturbance levels. In conclusion, the study
showed that boat traffic at current levels has only a temporary effect
on the haul out behavior of harbor seals in the M[eacute]tis Bay area.
In 2004, Johnson and Acevedo-Gutierrez (2007) evaluated the
efficacy of buffer zones for watercraft around harbor seal haulout
sites on Yellow Island, Washington State. The authors estimated the
minimum distance between the vessels and the haulout sites; categorized
the vessel types; and evaluated seal responses to the disturbances.
During the course of the seven-weekend study, the authors recorded 14
human-related disturbances, which were associated with stopped
powerboats and kayaks. During these events, hauled out seals became
noticeably active and moved into the water. The flushing occurred when
stopped kayaks and powerboats were at distances as far as 453 and 1,217
ft (138 and 371 m) respectively. The authors note that the seals were
unaffected by passing powerboats, even those approaching as close as
128 ft (39 m), possibly indicating that the animals had become tolerant
of the brief presence of the vessels and ignored them. The authors
reported that on average, the seals quickly recovered from the
disturbances and returned to the haulout site in less than or equal to
60 minutes. Seal numbers did not return to pre-disturbance levels
within 180 minutes of the disturbance less than one quarter of the time
observed. The study concluded that the return of seal numbers to pre-
disturbance levels and the relatively regular seasonal cycle in
abundance throughout the area counter the idea that disturbances from
powerboats may result in site abandonment (Johnson and Acevedo-
Gutierrez, 2007). Specific reactions from past NPS gull monitoring
surveys are detailed in this proposed rule's Estimated Take Section.
Vessel Strike
Glacier Bay
The probability of vessel and marine mammal interactions (i.e.,
motorboat strike) occurring during the proposed research activities is
unlikely due to the motorboat's slow operational speed, which is
typically 2 to 3 kn (2.3 to 3.4 mph) and the researchers continually
scanning the water for marine mammals presence during transit to the
islands. Thus, NMFS does not anticipate that strikes or collisions
would result from the movement of the motorboat.
SWAN
SWAN's survey vessels move at higher speeds, 8 to 12 kn, than those
used in the proposed GLBA NP activities, but vessel and marine mammal
interactions are still unlikely because the on board researchers are
constantly scanning the water for marine mammal presence. For SWAN's
activities, NMFS does not anticipate any strikes or collisions between
vessels and marine mammals.
[[Page 64086]]
Harbor Seal Pupping
Glacier Bay
During the harbor seal breeding (May-June) and molting (August)
periods, ~66 percent of seals in Glacier Bay inhabit the primary
glacial ice site and ~22 percent of seals are found in and adjacent to
a group of islands in the southeast portion of Glacier Bay. At the
proposed GLBA NP study sites, in 2016 only one pup was observed and no
pups were observed during project activities in 2017 and 2015. Pups
have been observed during NPS aerial surveys during the pupping seasons
(conducted during low tide), but in few numbers (see Table 4). NMFS
does not anticipate that the proposed activities would result in
separation of mothers and pups as pups are rarely seen at the study
sites.

\1\ A quantity calculated to indicate the extent of deviation for a group of pups as a whole.
SWAN
Based on aerial surveys between 2003 and 2005, the upper portions
of KBAY had high harbor seal pup abundance during the peak pupping
season (June) (Boveng at al, 2011). Proposed KBAY survey transects
occur in this area of high abundance (See Figure 5 in LOA application).
Boveng et al (2011) found that within Cook Inlet, June harbor seal pup
abundance in an individual survey unit correlated positively with June
adult abundance in that unit. Therefore, based on the anticipated
presence of adult harbor seals, there are also likely pups present at
sites in KATM and KEFJ during the pupping season (June). Despite the
presence of pups, SWAN's research and monitoring activities are
expected to result in minimal disturbance to the hauled out harbor
seals of all life stages due to the distance and duration of the
vessel's presence (see Proposed Mitigation), and NMFS does not
anticipate that the proposed activities would result in separation of
mothers and pups.
Steller Sea Lion Pupping
SWAN
During the Steller sea lion pupping season (May-July), mothers
spend time both on land with their pups and at sea foraging. Because
SWAN's proposed surveys avoid transects that pass Steller sea lion
rookeries, NMFS does not anticipate any impacts on hauled out Steller
sea lion mothers and their pups.
Summary
Based on studies described here and previous monitoring reports
from GLBA NP (Discussed further in the Estimated Take Section), we
anticipate that any pinnipeds found in the vicinity of the proposed
projects in both GLBA NP and the SWAN region could have short-term
behavioral reactions (i.e., may result in marine mammals avoiding
certain areas) due to noise and visual disturbance generated by: (1)
Motorboat approaches and departures and (2) human presence during
research and monitoring activities. We would expect the pinnipeds to
return to a haulout site within minutes to hours of the stimulus based
on previous research (Allen et al., 1984). Pinnipeds may be temporarily
displaced from their haulout sites, but we do not expect that the
pinnipeds would permanently abandon a haulout site during the conduct
of the proposed research as activities are short in duration (brief
transit through an area to up to two hours), and previous surveys have
demonstrated that pinnipeds have returned to their haulout sites and
have not permanently abandoned the sites.
NMFS does not anticipate that the proposed activities would result
in the injury, serious injury, or mortality of pinnipeds. NMFS does not
anticipate that vessel strikes would result from the movement of the
motorboat. The proposed activities will not result in any permanent
impact on habitats used by marine mammals, including prey species and
foraging habitat.
Marine Mammal Habitat
NMFS does not anticipate that the proposed operations in GLBA NP or
the SWAN region would result in any effects on the habitats used by the
marine mammals in the proposed area, including the food sources they
use (i.e., fish and invertebrates). The main impact associated with the
proposed activity will be temporarily elevated noise levels from
motorboats and human disturbance on marine mammals potentially leading
to temporary displacement from a site, previously discussed in this
proposed rule. NPS' LEIS for gull monitoring surveys in GLBA NP
concluded that the activities do not result in the loss or modification
to marine mammal habitat (NPS 2010). Additionally, any minor habitat
alterations stemming from the maintenance of NPS' weather station will
be located in an area that will not impact marine mammals. SWAN's
activities in KATM and KEFJ do occur in Steller sea lion critical
habitat, but will have minimal impact due to the nature of the
disturbance and explicit avoidance of the most sensitive areas
(rookeries). In all, the proposed activities in both GLBA NP and the
SWAN region will not result in any permanent impact on habitats used by
marine mammals, including prey species and foraging habitat.
Estimated Take
This section provides an estimate of the number of incidental takes
proposed for authorization through this IHA, which will inform both
NMFS's consideration of whether the number of takes is ``small'' and
the negligible impact determination.
Harassment is the only type of take expected to result from these
activities. Except with respect to certain activities not pertinent
here, section 3(18) of 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
[[Page 64087]]
wild by causing disruption of behavioral patterns, including, but not
limited to, migration, breathing, nursing, breeding, feeding, or
sheltering (Level B harassment).
Authorized takes would be by Level B harassment only, in the form
of disruption of behavioral patterns for individual marine mammals
resulting from exposure to motorboats and the presence of NPS
personnel. Based on the nature of the activity and proposed mitigation
measures, Level A harassment is neither anticipated nor proposed to be
authorized. As described previously, no mortality is anticipated or
proposed to be authorized for this activity. Below we describe how the
take is estimated.
Glacier Bay
In GLBA NP, harbor seals may be disturbed when vessels approach or
researchers go ashore for the purpose of monitoring gull colonies and
for the maintenance of the Lone Island weather tower. Harbor seals tend
to haul out in small numbers at study sites. Using monitoring report
data from 2015 to 2017 (see raw data from Tables 1 of the 2017, 2016
and 2015 Monitoring Reports, which are available online at: https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-research-and-other-activities), the average number
of harbor seals per survey visit was calculated to estimate the
approximate number of seals observers would find on any given survey
day. As a result, the following averages were determined for each
island: Boulder Island--average 3.45 seals, Flapjack Island--average
10.10 seals, Geikie Rock--average 9.58 seals, and Lone Island average
of 18.91 seals (See Table 5). Estimated take for gull and climate
monitoring was calculated by multiplying the average number of seals
observed during past gull monitoring surveys (2015-2017) by the number
of total site visits. This includes five annual visits to Boulder
Island, Flapjack Island, and Geikie Rock and eight annual visits to
Lone Island (to include three site visits for climate monitoring
activities). Therefore, the total estimated annual incidents of
harassment equals 267 which totals to 1,335 takes during the entire
five years of the proposed activities (See Table 5).
During climate monitoring, which is expected to take place from
March to April and October to February, seal numbers are expected to
dramatically decline within the action area. Although harbor seal
survey data within GLBA NP is lacking for the months of October through
February, results from satellite telemetry studies suggest that harbor
seals travel extensively beyond the boundaries of GLBA NP during the
post-breeding season (September-April) (Womble and Gende, 2013b).
Therefore, using the latest observation data from past gull monitoring
activities (that occurred from May to September) is applicable when
estimating take for climate monitoring activities, as it will provide
the most conservative estimates.

SWAN
Harbor seals and Steller sea lions may be disturbed by vessel
presence, movement, or noise during the execution of SWAN's survey
transects. The estimated number of takes by Level B harassment included
in Table 6 are based on numbers of pinnipeds observed from a similar
survey of KATM and KEFJ in 2013. In this survey, researchers observed
an estimated 100 harbor seals and 100 Steller sea lions during each of
the KATM and KEFJ surveys. Data from 2013 surveys were used to estimate
take because in 2013, most of the transects were able to be completed.
Thus, 2013 data offers the most conservative count-based estimate.
Based on pinnipeds observed in 2013, NPS estimates that each year,
across the three survey sites, SWAN's activities will result in take by
Level B harassment of 300 harbor seals and 200 Steller sea lions. The
observed number of harbor seals has been increased by 100 to account
for the previously not surveyed KBAY, resulting in an estimated 1500
harbor seal and 1000 Steller sea lion takes by Level B harassment
across the five years. For harbor seals, NPS estimates that 100
individuals will experience take by Level B harassment in each survey
area each year. Annually, that would mean 200 harbor seal takes by
Level B harassment in the Cook Inlet/Shelikof Strait stock (1000 over 5
years), and 100 harbor seal takes by Level B harassment from the Prince
William Sound stock (500 over 5 years). For Steller sea lion takes by
Level B harassment, NPS estimates that 100 individuals will experience
take by Level B harassment each year in KATM and KEFJ. However, no
takes by Level B harassment will occur in KBAY because Steller sea
lions are not common in KBAY. For simplicity, NMFS assumes and analyzes
the impacts of the full Steller sea lion take on both the eastern and
western stocks. Because these estimates are based on observations of
pinnipeds and not harassments, NMFS considers the estimated numbers of
take by Level B harassment presented in Table 6 conservative.
---------------------------------------------------------------------------

pinniped disturbance reactions by severity. NMFS only considers
responses falling into Levels 2 and 3 as harassment (Level B Take)
under the MMPA.

Effects of Specified Activities on Subsistence Uses of Marine Mammals
The availability of the affected marine mammal stocks or species
for subsistence uses may be impacted by this activity, though this is
not an anticipated outcome. The subsistence uses that may be affected
and the potential impacts of the activity on those uses are described
below. Measures included in these proposed regulations to reduce the
impacts of the activity on subsistence uses are identical to those
which minimize disturbance of pinnipeds as described in the Proposed
Mitigation section. Last, the information from this section and the
Proposed Mitigation section is analyzed to determine whether the
necessary findings may be made in the Unmitigable Adverse Impact
Analysis and Determination section.
Subsistence harvest of pinnipeds is prohibited in GLBA NP, KATM,
and KEFJ but it does occur in nearby areas outside park boundaries.
Native communities near KBAY, including Homer, Seldovia, Nanwalek, and
Port Graham harvested an estimated 32 harbor seals and 3 Steller sea
lions in 2007 (Wolfe et al. 2009). It is not known exactly where these
pinnipeds were harvested but some of them could potentially have been
harvested in KBAY. 2007 harvest of both Steller sea lions and harbor
seals was at a low point in June and July when SWAN's surveys would
occur in KBAY. Additionally, the disturbance to pinnipeds caused by
NPS's activities is limited to non-lethal take by Level B harassment
and is temporary and short in duration. Because the subsistence harvest
is separated in time and space from NPS's proposed activities, and the
disturbance should not result in anything other than short term
(minutes to hours) avoidance of haulouts, there should be no impacts on
subsistence harvest.
Proposed Mitigation
In order to issue an incidental take authorization (ITA) under
section 101(a)(5)(A) of the MMPA, NMFS must set forth the permissible
methods of taking pursuant to such activity, ``and other means of
effecting the least practicable 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. NMFS regulations
require applicants for ITAs to include information about the
availability and feasibility (economic and technological) of equipment,
methods, and manner of conducting such activity or other means of
effecting the least practicable adverse impact upon the affected
species or stocks and their habitat (50 CFR 216.104(a)(11)).
In evaluating how mitigation may or may not be appropriate to
ensure the least practicable adverse impact on species or stocks and
their habitat, as well as on subsistence uses where applicable, we
carefully consider two primary factors:
(1) The manner in which, and the degree to which, the successful
implementation of the measure(s) is expected to reduce impacts to
marine mammals, marine mammal species or stocks, and their habitat.
This considers the nature of the potential adverse impact being
mitigated (likelihood, scope, range). It further considers the
likelihood that the measure will be effective if implemented
(probability of accomplishing the mitigating result if implemented as
planned) the likelihood of effective implementation (probability of
implementing as planned); and
(2) The practicability of the measures for applicant
implementation, which may consider such things as cost, impact on
operations, and, in the case of a military readiness activity,
personnel safety, practicality of implementation, and impact on the
effectiveness of the military readiness activity.
Glacier Bay
NPS has based the mitigation measures which they propose to
implement during the proposed research, on the following: (1) Protocols
used during previous gull research activities as required by our
previous authorizations for these activities; and (2) recommended best
practices in Womble et al. (2013a); Richardson et al. (1995); and Weir
and Dolman (2007).
To reduce the potential for disturbance from acoustic and visual
stimuli associated with gull and climate monitoring activities within
GBLA NP, NPS has proposed to implement the following mitigation
measures for marine mammals:
Pre-Survey Monitoring
Before all surveys, the lead NPS biologist will instruct additional
survey crew on appropriate conduct when in the vicinity of hauled-out
marine mammals. This training shall brief survey personnel on marine
mammals (inclusive of identification as needed, e.g., neonates). Prior
to deciding to land onshore to conduct gull and climate monitoring, 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. If offshore
predators, harbor seal pups of less than one week of age (i.e.,
neonates), or Steller sea lions are observed, researchers will follow
the protocols for site avoidance discussed below. If neither of these
instances occur, researchers will then perform a controlled landing on
the survey site.
Site Avoidance
If a harbor seal pup less than one week old (i.e,. neonates) or a
harbor seal predator (i.e., killer whale) is observed near or within
the action area, researchers will not go ashore to conduct gull or
climate monitoring activities. Also, if Steller sea lions are observed
within or near the study site, researchers will maintain a distance of
[[Page 64089]]
at least 100 m from the animals at all times.
Controlled Landings
The researchers would determine whether to approach an island study
site based on type of animals present. Researchers would approach the
island by motorboat at a speed of approximately 2 to 3 kn (2.3 to 3.4
mph). This would provide enough time for any marine mammals present to
slowly enter the water without panic (flushing). The researchers would
also select a pathway of approach farthest from the hauled-out harbor
seals to minimize disturbance.
Minimize Predator Interactions
During pre-survey monitoring on approach to a site, NPS will
observe the surrounding area for predators. If the researchers visually
observe marine predators (i.e., killer whales) present within a one
mile radius of hauled-out marine mammals, the researchers would not
approach the study site.
Disturbance 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.
Whale Avoidance
Although humpback whales and killer whales are not expected to be
impacted by the proposed activities at GLBA NP, avoidance measures will
be taken if humpback whales or killer whales are observed. Based on
regulations (81 FR 62018; September 8, 2016), NPS will avoid operation
of a motor vessel within \1/4\ nautical mile of a whale. If
accidentally positioned within \1/4\ nautical mile of a whale,
researchers will slow the vessel speed to 10 knots or less and maintain
course away from the whale until at least \1/4\ nautical mile of
separation exists.
SWAN
NPS has based the mitigation measures which they propose to
implement at SWAN on the following: (1) Protocols used during previous
authorizations for similar GLBA NP research; (2) recommended best
practices in Womble et al. (2013a); Richardson et al. (1995); and Weir
and Dolman (2007); and (3) experience of SWAN researchers in previous
surveys.
To reduce the potential for disturbance from acoustic and visual
stimuli associated with SWAN's surveys, NPS has proposed to implement
the following mitigation measures for marine mammals:
Disturbance Reduction Protocols
While surveying study sites, the researchers will maintain a vessel
distance of 100 to 150 m from shorelines at all times. If hauled out
Steller sea lions and harbor seals are observed, the survey would
maintain speed and minimum distance from the haulout to avoid
startling. Additionally the survey will be attempted from a distance
greater than 150 m, if conditions allow proper execution of the survey
at that distance.
Rookery Avoidance
SWAN will avoid transects that pass known Steller sea lion rookery
beaches in order to minimize disturbance of these rookeries and the
surrounding critical habitat.
Whale Avoidance
Although humpback and beluga whales are not expected to be impacted
by SWAN's proposed work, avoidance measures will be taken if these
species are observed. Based on regulations (81 FR 62018; September 8,
2016), SWAN will avoid operation of a motor vessel within \1/4\ mile of
a whale. If accidentally positioned within \1/4\ nautical mile of a
whale, researchers will slow the vessel speed to 10 knots or less and
maintain course away from the whale until at least \1/4\ nautical mile
of separation exists.
Mitigation Conclusions
Based on our evaluation of the applicant's proposed measures, as
well as other measures considered by NMFS, NMFS has preliminarily
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, areas of similar significance, and on the availability
of such species or stock for subsistence uses.
Proposed Monitoring and Reporting
In order to issue an ITA for an activity, section 101(a)(5)(A) 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 are expected to be present in the
proposed action area. Effective reporting is critical both to
compliance as well as ensuring that the most value is obtained from the
required monitoring.
Monitoring and reporting requirements prescribed by NMFS should
contribute to improved understanding of one or more of the following:
Occurrence of marine mammal species or stocks in the area
in which take is anticipated (e.g., presence, abundance, distribution,
density);
Nature, scope, or context of likely marine mammal exposure
to potential stressors/impacts (individual or cumulative, acute or
chronic), through better understanding of: (1) Action or environment
(e.g., source characterization, propagation, ambient noise); (2)
affected species (e.g., life history, dive patterns); (3) co-occurrence
of marine mammal species with the action; or (4) biological or
behavioral context of exposure (e.g., age, calving or feeding areas);
Individual marine mammal responses (behavioral or
physiological) to acoustic stressors (acute, chronic, or cumulative),
other stressors, or cumulative impacts from multiple stressors;
How anticipated responses to stressors impact either: (1)
Long-term fitness and survival of individual marine mammals; or (2)
populations, species, or stocks;
Effects on marine mammal habitat (e.g., marine mammal prey
species, acoustic habitat, or other important physical components of
marine mammal habitat); and
Mitigation and monitoring effectiveness.
SWAN
NPS proposes to conduct marine mammal monitoring during the SWAN
activities, in order to implement the mitigation measures that require
real-time monitoring and to gain a better understanding of marine
mammals and their impacts to the project's activities. Because the
activity is a survey of marine birds and mammals in the area,
researchers will naturally be monitoring the area for pinnipeds or
other marine mammals during all activities. Monitoring activities will
consist of conducting and recording observations of pinnipeds within
the vicinity of the proposed research areas. The monitoring notes would
provide dates, transect location, species, numbers of animals present
within the transect, and numbers of pinnipeds that flushed into the
water.
[[Page 64090]]
The method for recording disturbances follows those in Mortenson
(1996). For NPS' activities in the SWAN region, pinniped disturbances
would be based on a three-point scale that represents an increasing
response to the disturbance (Table 3). Because SWAN surveys are
conducted at speed, researchers will be able to record the total number
of each pinniped species observed and the number of Level 3 (Flushing)
responses that occur, but not other, less noticeable disturbance
responses.
SWAN does not have previous monitoring aimed specifically at
recording and quantifying marine mammal disturbance. Similarity between
the GLBA NP and SWAN proposed activities for this proposed rule suggest
mitigation measures based on relevant portions of previous GLBA NP
authorizations will provide the means of effecting the least
practicable impact on the species or stock in the SWAN activity.
GLBA NP
NPS proposes to conduct marine mammal monitoring during the present
GLBA NP project, in order to implement the mitigation measures that
require real-time monitoring and to gain a better understanding of
marine mammals and their impacts to the project's activities. In
addition, NPS's monitoring plan is guiding additional monitoring effort
designed to answer questions of interest regarding pinniped usage of
GLBA NP haulouts and the effects of NPS's activity on these local
populations. The researchers will monitor the area for pinnipeds during
all research activities. Monitoring activities will consist of
conducting and recording observations of pinnipeds within the vicinity
of the proposed research areas. The monitoring notes would provide
dates, location, species, the researcher's activity, behavioral state,
numbers of animals that were alert or moved greater than one meter, and
numbers of pinnipeds that flushed into the water.
The method for recording disturbances follows those in Mortenson
(1996). NPS activities in GLBA NP would record pinniped disturbances on
a three-point scale that represents an increasing response to the
disturbance (Table 3). Both a level 2 and level 3 response would be
recorded as a take by Level B harassment. NPS will record the time,
source, and duration of the disturbance, as well as an estimated
distance between the source and haulout.
Previous Monitoring Results
NPS has complied with the monitoring requirements under the
previous GLBA NP authorizations. NMFS posted the 2017 report on our
website at https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-research-and-other-activities
and the results from the previous NPS monitoring reports support our
findings that the mitigation measures required under the 2014--2017
Authorizations provide the means of effecting the least practicable
impact on the species or stock in the GLBA NP activity. During the last
3 years of GLBA NP activity, approximately a third of all observed
harbor seals have flushed in response to these activities (37 percent
in 2015, 37 percent in 2016, and 38 percent in 2017). The following
narratives provide a detailed account of each of the past 3 years of
monitoring for the GLBA NP activity (Summarized in Table 7):
In 2017, of the 86 harbor seals that were observed: 33 flushed in
to the water, 0 became alert but did not move >1 m, and 0 moved >1 m
but did not flush into the water. In all, no harbor seal pups were
observed. On two occasions, harbor seals were flushed into the water
when islands were accessed for gull surveys. In these instances, the
vessel approached the island at a very slow speed and most of the
harbor seals flushed into the water at approximately 150--185 m. On two
events, harbor seals were observed hauled out on Boulder Island and not
disturbed due to their distance from the survey area. In addition,
during two pre-monitoring surveys conducted for Lone Island, harbor
seals were observed hauled out and the survey was not conducted to
prevent disturbance of harbor seals.
In 2016, of the 216 harbor seals that were observed: 77 Flushed in
to the water; 3 became alert but did not move >1 m, and 17 moved >1 m
but did not flush into the water. On five occasions, harbor seals were
flushed into the water when islands were accessed for gull surveys. In
these instances, the vessel approached the island at a very slow speed
and most of the harbor seals flushed into the water at approximately
50-100 m. In four instances, fewer than 25 harbor seals were present,
but in one instance, 41 harbor seals were observed flushing into the
water when NPS first saw them as they rounded a point of land in kayaks
accessing Flapjack Island. In five instances, harbor seals were
observed hauled out and not disturbed due to their distance from the
survey areas.
In 2015, of the 156 harbor seals that were observed: 57 Flushed in
to the water; 25 became alert but did not move >1 m, and 0 moved >1 m
but did not flush into the water. No pups were observed. On 2
occasions, harbor seals were observed at the study sites in numbers <25
and the islands were accessed for gull surveys. In these instances, the
vessel approached the island at very slow speed and most of the harbor
seals flushed into water at approximately 200 m (Geikie 8/5/15) and 280
m (Lone, 8/5/15). In one instance, (Lone, 6/11/15) NPS counted 20
harbor seals hauled out during the initial vessel-based monitoring, but
once on the island, NPS observed 33 hauled out seals. When NPS realized
the number of seals present, they ceased the survey and left the area,
flushing 13 seals into the water.

Coordination
NPS can add to the knowledge of pinnipeds in the proposed action
area by noting observations of: (1) Unusual behaviors, numbers, or
distributions of pinnipeds, such that any potential follow-up research
can be conducted by the appropriate personnel; (2) tag-bearing
carcasses of pinnipeds, allowing transmittal of the information to
appropriate agencies and personnel; and
[[Page 64091]]
(3) rare or unusual species of marine mammals for agency follow-up.
Glacier Bay
NPS actively monitors harbor seals at breeding and molting haulout
locations to assess trends over time (e.g., Mathews & Pendleton, 2006;
Womble et al. 2010, Womble and Gende, 2013b). NPS's monitoring plan is
guiding additional monitoring effort designed to answer questions of
interest regarding pinniped usage of GLBA NP haulouts and the effects
of NPS's activity on these local populations. This monitoring program
involves collaborations with biologists from the Alaska Department of
Fish and Game, and the NMFS Alaska Fisheries Science Center. NPS will
continue these collaborations and encourage continued or renewed
monitoring of marine mammal species. NPS will coordinate with state and
Federal marine mammal biologists to determine what additional data or
observations may be useful for monitoring marine mammals and haulouts
in GLBA NP. Additionally, NPS would report vessel-based counts of
marine mammals, branded, or injured animals, and all observed
disturbances to the appropriate state and Federal agencies.
SWAN
NPS is establishing a monitoring program for pinnipeds in the SWAN
region through its marine bird and marine mammal surveys. NPS will also
coordinate with state and Federal marine mammal biologists to determine
what additional data or observations may be useful for monitoring
marine mammals and haul outs in the SWAN survey areas.
SWAN has been conducting nearshore coastal surveys along the KATM
and KEFJ since 2006 and 2007, respectively (Coletti et al., 2018). SWAN
collaborates closely with U.S. Geological Survey, U.S. Fish and
Wildlife Service, the University of Alaska Fairbanks and others under
the Gulf Watch Alaska (https://www.gulfwatchalaska.org/) program,
primarily funded by the Exxon Valdez Oil Spill Trustee Council. SWAN
will continue these collaborations and encourage continued or renewed
monitoring of marine mammal species. Additionally, NPS will report
vessel-based counts of marine mammals, branded or injured animals, and
all observed disturbances to state and Federal agencies.
Reporting
SWAN and GLBA NP are each required to submit separate draft annual
reports on all activities and marine mammal monitoring results to NMFS
within ninety days following the end of its monitoring period. These
reports will include a summary of the information gathered pursuant to
the monitoring requirements set forth in the Authorization. SWAN and
GLBA NP will submit final reports to NMFS within 30 days after
receiving comments on the draft report. If SWAN or GLBA NP receive no
comments from NMFS on the report, NMFS will consider the draft report
to be the final report. NPS will also submit a comprehensive 5-year
report covering all activities conducted under the incidental take
regulations 90 days following expiration of these regulations or, if
new regulations are sought, no later than 90 days prior to expiration
of the regulations.
Each 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 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;
and
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.), NPS shall
immediately cease the specified activities and immediately report the
incident to the Office of Protected Resources, NMFS and the Alaska
Regional Stranding Coordinator. The report must include the following
information:
Time, date, and location (latitude/longitude) of the
incident;
Description and location of the incident (including tide
level 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).
NPS shall not resume its activities until NMFS is able to review
the circumstances of the prohibited take. NMFS will work with NPS to
determine what is necessary to minimize the likelihood of further
prohibited take and ensure MMPA compliance. NPS may not resume their
activities until notified by us via letter, email, or telephone.
In the event that NPS 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), NPS will immediately report the incident to the Office of
Protected Resources, NMFS and the Alaska Regional Stranding
Coordinator. The report must include the same information identified in
the paragraph above. Activities may continue while we review the
circumstances of the incident. We will work with NPS to determine
whether modifications in the activities are appropriate.
In the event that NPS 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), NPS will report the incident to
the incident to the Office of Protected Resources, NMFS and the Alaska
Regional Stranding Coordinator within 24 hours of the discovery. NPS
researchers will provide photographs or video footage (if available) or
other documentation of the stranded animal sighting to us. NPS can
continue their research activities.
Negligible Impact Analysis and Determination
NMFS has defined negligible impact 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 (50 CFR 216.103). A
negligible impact finding is based on the lack of likely adverse
effects on annual rates of recruitment or survival (i.e., population-
level effects). An estimate of the number of takes alone is not enough
information on which to base an impact determination. In addition to
considering estimates of the number of
[[Page 64092]]
marine mammals that might be ``taken'' through harassment, NMFS
considers other factors, such as the likely nature of any responses
(e.g., intensity, duration), the context of any responses (e.g.,
critical reproductive time or location, migration), as well as effects
on habitat, and the likely effectiveness of the mitigation. We also
assess the number, intensity, and context of estimated takes by
evaluating this information relative to population status. Consistent
with the 1989 preamble for NMFS's implementing regulations (54 FR
40338; September 29, 1989), the impacts from other past and ongoing
anthropogenic activities are incorporated into this analysis via their
impacts on the environmental baseline (e.g., as reflected in the
regulatory status of the species, population size and growth rate where
known, ongoing sources of human-caused mortality, or ambient noise
levels).
During these activities, harbor seals and Steller sea lions may
exhibit behavioral modifications, including temporarily vacating the
area during the proposed research and monitoring activities to avoid
human and vessel disturbance. However, due to the project's minimal
levels of visual and acoustic disturbance (Level B harassment only),
NMFS does not expect NPS's specified activities to cause long-term
behavioral disturbance, abandonment of the haulout area, injury,
serious injury, or mortality. In addition, while a portion of these
proposed activities would take place in areas of significance for
marine mammal feeding, resting, breeding, or pupping, there would be no
adverse impacts on marine mammal habitat as discussed above. Due to the
nature, degree, and context of the behavioral harassment anticipated,
we do not expect the activities to impact annual rates of recruitment
or survival.
NMFS does not expect pinnipeds to permanently abandon any area
surveyed by NPS researchers, as is evidenced by continued presence of
pinnipeds at the GLBA NP sites during annual gull and climate
monitoring. NMFS anticipates that impacts to hauled-out harbor seals
and Steller sea lions during NPS' research and monitoring activities
would be behavioral harassment of limited duration (i.e., up to two
hours per site visit) and limited intensity (i.e., temporary flushing
at most).
In summary and as described above, the following factors primarily
support our preliminary determination that the impacts resulting from
this activity are not expected to adversely affect the species or stock
through effects on annual rates of recruitment or survival:
No mortality is anticipated or authorized;
The takes from Level B harassment would be due to
potential behavioral disturbance;
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;
The proposed activities would partially take place in
areas of significance for marine mammal feeding, resting, breeding, or
pupping but due to their nature and duration would not adversely impact
marine mammal habitat or deny pinnipeds access to this habitat because
of the large availability of alternate haulouts and short-duration of
disturbance;
Anecdotal observations and results from previous
monitoring reports show that the pinnipeds returned to the various
sites and did not permanently abandon haulout sites after NPS conducted
their research activities; and
Harbor seals and Steller sea lions may flush into the
water despite researchers best efforts to keep calm and quiet around
these pinnipeds; however, injury or mortality has never been documented
and is not anticipated from flushing events. GLBA NP researchers would
approach study sites slowly to provide enough time for any marine
mammals present to slowly enter the water without panic. SWAN
researchers would attempt to conduct their surveys at a distance which
would not result in pinniped disturbance.
Based on the analysis contained herein of the likely effects of the
specified activity on marine mammals and their habitat, and taking into
consideration the implementation of the proposed monitoring and
mitigation measures, NMFS preliminarily finds that the total marine
mammal take from the proposed activity will have a negligible impact on
all affected marine mammal species or stocks.
Small Numbers Analysis
As noted above, only small numbers of incidental take may be
authorized under Section 101(a)(5)(D) of the MMPA for specified
activities other than military readiness activities. The MMPA does not
define small numbers and so, in practice, where estimated numbers are
available, NMFS compares the number of individuals proposed to be taken
to the most appropriate estimation of abundance of the relevant species
or stock in our determination of whether an authorization is limited to
small numbers of marine mammals. Additionally, other qualitative
factors may be considered in the analysis, such as the temporal or
spatial scale of the activities.
As mentioned previously, NMFS estimates that NPS' research
activities, including gull monitoring, climate monitoring, and marine
animal surveys, could potentially affect, by Level B harassment only,
two species of marine mammal under our jurisdiction. For harbor seals,
this annual take estimate is small relative to the three impacted
stocks, ranging from 0.3 to 3.7 percent (See Table 1, Table 5, and
Table 6). For Steller sea lions, this annual take estimate is small
(200 sea lions) relative to the western stock (0.4 percent) or eastern
stock (0.5 percent). In addition to this, there is a high probability
in the GLBA NP activities that repetitive takes of the same animal may
occur which reduces the percentage of population impacted even further.
Based on the analysis contained herein of the proposed activity
(including the proposed mitigation and monitoring measures) and the
anticipated take of marine mammals, NMFS preliminarily finds that small
numbers of marine mammals will be taken relative to the population size
of the affected species or stocks.
Impact on Availability of Affected Species for Taking for Subsistence
Uses
There are no relevant subsistence uses of marine mammals implicated
by the specified activities in GLBA NP, KATM, or KEFJ. Subsistence
harvest is prohibited in these national parks and the nature of the
activities means they should not affect any harvest occurring in nearby
waters. There is possible pinniped harvest in KBAY, but the timing of
the survey is removed from the peak seasons of harvest. Additionally,
the disturbance to pinnipeds caused by NPS's activities is limited to
non-lethal take by Level B harassment and is temporary and short in
duration. Therefore, we have preliminarily determined that the total
taking of affected species or stocks would not have an unmitigable
adverse impact on the availability of such species or stocks for taking
for subsistence purposes.
Endangered Species Act (ESA)
Section 7(a)(2) of the Endangered Species Act of 1973 (ESA: 16
U.S.C. 1531 et seq.) requires that each Federal agency insure that any
action it authorizes, funds, or carries out is not likely to jeopardize
the continued existence of any endangered or threatened species or
result in the destruction or adverse modification of designated
critical habitat. To ensure ESA compliance for the issuance of
[[Page 64093]]
incidental take regulations and subsequent LOAs, NMFS consults
internally, in this case with the Alaska Regional Office, whenever we
propose to authorize take for endangered or threatened species.
NMFS is proposing to authorize take of western DPS Steller sea
lions, which are listed under the ESA.
NMFS's Office of Protected Resources has requested initiation of
Section 7 consultation with NMFS's Alaska Regional Office for the
issuance of this LOA. NMFS will conclude the ESA consultation prior to
reaching a determination regarding the proposed issuance of the
authorization.
Adaptive Management
The regulations governing the take of marine mammals incidental to
NPS research and monitoring activities in GLBA NP and SWAN region would
contain an adaptive management component.
The reporting requirements associated with this proposed rule are
designed to provide NMFS with monitoring data from the previous year to
allow consideration of whether any changes are appropriate. The use of
adaptive management allows NMFS to consider new information from
different sources to determine (with input from NPS regarding
practicability) on an annual or biennial basis if mitigation or
monitoring measures should be modified (including additions or
deletions). Mitigation measures could be modified if new data suggests
that such modifications would have a reasonable likelihood of reducing
adverse effects to marine mammals and if the measures are practicable.
NPS's monitoring program (see ``Proposed Monitoring and
Reporting'') would be managed adaptively. Changes to the proposed
monitoring program may be adopted if they are reasonably likely to
better accomplish the MMPA monitoring goals described previously or may
better answer the specific questions associated with NPS's monitoring
plan.
The following are some of the possible sources of applicable data
to be considered through the adaptive management process: (1) Results
from monitoring reports, as required by MMPA authorizations; (2)
results from general marine mammal and sound research; and (3) any
information which reveals that marine mammals may have been taken in a
manner, extent, or number not authorized by these regulations or
subsequent LOAs.
Request for Information
NMFS requests interested persons to submit comments, information,
and suggestions concerning NPS's request and the proposed regulations
(see ADDRESSES). All comments will be reviewed and evaluated as we
prepare the final rule and make final determinations on whether to
issue the requested authorizations. This notice and referenced
documents provide all environmental information relating to our
proposed action for public review.
Classification
Pursuant to the procedures established to implement Executive Order
12866, the Office of Management and Budget has determined that this
proposed rule is not significant.
Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA),
the Chief Counsel for Regulation of the Department of Commerce has
certified to the Chief Counsel for Advocacy of the Small Business
Administration that this proposed rule, if adopted, would not have a
significant economic impact on a substantial number of small entities.
NPS is the sole entity that would be subject to the requirements in
these proposed regulations, and the NPS is not a small governmental
jurisdiction, small organization, or small business, as defined by the
RFA. Because of this certification, a regulatory flexibility analysis
is not required and none has been prepared.
Notwithstanding any other provision of law, no person is required
to respond to nor shall a person be subject to a penalty for failure to
comply with a collection of information subject to the requirements of
the Paperwork Reduction Act (PRA) unless that collection of information
displays a currently valid OMB control number. However, this proposed
rule does not contain a collection-of-information requirement subject
to the provisions of the Paperwork Reduction Act (PRA) because the
applicant is a Federal agency, and the information is not ``uses for
general statistical purposes''. 44 U.S.C. 3502(3)(A).

Sec. 217.24 Mitigation requirements.
When conducting the activities identified in Sec. 217.20(a), the
mitigation measures contained in any LOA issued under Sec. 216.106 of
this chapter and Sec. 217.24 must be implemented. These mitigation
measures shall include but are not limited to:
(a) General conditions: (1) A copy of any issued LOA must be in the
possession of NPS, its designees, and additional survey crew personnel
operating under the authority of the issued LOA.
(2) Before all surveys, the lead NPS biologist must instruct
additional survey crew on appropriate conduct when in the vicinity of
hauled-out marine mammals. This training must brief survey personnel on
marine mammals (inclusive of identification as needed, e.g., neonates).
(3) If humpback whales, killer whales, or beluga whales are
observed, NPS must avoid operation of a motor vessel within \1/4\
nautical mile of a whale. If accidentally positioned within \1/4\
nautical mile of a whale, NPS must slow the vessel speed to 10 knots or
less and maintain course away from the whale until at least \1/4\
nautical mile of separation exists.
(b) Glacier Bay Gull and Climate Monitoring. (1) On an annual
basis, NPS may conduct a maximum of five days of gull monitoring for
each survey location listed in the LOA.
(2) On an annual basis, the NPS may conduct a maximum of three days
of activities related to climate monitoring on Lone Island.
(3) NPS is required to conduct pre-survey monitoring before
deciding to access a study site.
(4) Prior to deciding to land onshore, NPS must use high-powered
image stabilizing binoculars before approaching at distances of greater
than 500 m (1,640 ft) to determine and document the number, species,
and location of hauled-out marine mammals.
(5) During pre-survey monitoring, vessels must maintain a distance
of 328 to 1,640 ft (100 to 500 m) from the shoreline.
(6) If a harbor seal pup less than one week of age (neonate) is
present within or near a study site or a path to a study site, NPS must
not access the site nor conduct the study at that time. In addition, if
during the activity, a pup less than one week of age is observed, all
research activities must conclude for the day.
(7) NPS must maintain a distance of at least 100 m from any Steller
sea lion;
(8) NPS must perform controlled and slow ingress to islands where
harbor seals are present.
(9) NPS must monitor for offshore predators at the study sites
during pre-survey monitoring and must avoid research activities when
killer whales (Orcinus orca) or other predators are observed within a 1
mile radius.
(10) NPS must maintain a quiet working atmosphere, avoid loud
noises, and must use hushed voices in the presence of hauled-out
pinnipeds.
(c) SWAN Marine bird and mammal surveys. (1) On an annual basis,
NPS may conduct one summer survey at each location listed in the LOA.
(2) On an annual basis, the NPS may conduct one winter survey at
each location listed in the LOA.
(3) NPS must maintain a minimum vessel distance of 100 meters from
the shoreline at all times while surveying.
(4) If hauled out Steller sea lions or harbor seals are observed,
NPS must maintain the vessel speed and minimum distance. If survey
conditions allow, the survey will be attempted from a distance greater
than 150 meters.
Sec. 217.25 Requirements for monitoring and reporting.
NPS is required to conduct marine mammal monitoring during research
and monitoring activities. NPS and/or its designees must record the
following for the designated monitoring activity:
(a) Glacier Bay Gull and Climate Monitoring. (1) Species counts
(with numbers of adults/juveniles); and numbers of disturbances, by
species and age, according to a three-point scale of intensity;
(2) Information on the weather, including the tidal state and
horizontal visibility;
(3) The observer will note the presence of any offshore predators
(date, time, number, and species); and
(4) The observer will note unusual behaviors, numbers, or
distributions of pinnipeds, such that any potential follow-up research
can be conducted by the appropriate personnel; marked or tag-bearing
pinnipeds or carcasses, allowing transmittal of the information to
appropriate agencies; and any rare or unusual species of marine mammal
for agency follow-up. The observer will report that information to
NMFS's Alaska Fisheries Science Center and/or the Alaska Department of
Fish and Game Marine Mammal Program.
(b) SWAN Marine Bird and Mammal Surveying. (1) Species counts and
numbers of type 3, flushing, disturbances;
(2) Information on the weather, including the tidal state and
horizontal visibility; and
(3) The observer will note unusual behaviors, numbers, or
distributions of pinnipeds, such that any potential follow-up research
can be conducted by the appropriate personnel; marked or tag-bearing
pinnipeds or carcasses, allowing transmittal of the information to
appropriate agencies; and any rare or unusual species of marine mammal
for agency follow-up. The observer will report that information to
NMFS's Alaska Fisheries Science Center and/or the Alaska Department of
Fish and Game Marine Mammal Program.
(c) NPS must submit separate annual draft reports for GLBA NP and
SWAN on all monitoring conducted within ninety calendar days of the
completion of annual research and monitoring activities. Final reports
for both GLBA NP and SWAN must be prepared and submitted within thirty
days following resolution of comments on each draft report from NMFS.
This report must contain:
(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; and
(4) A description of the implementation and effectiveness of the
monitoring and mitigation measures of
[[Page 64095]]
the Authorization and full documentation of methods, results, and
interpretation pertaining to all monitoring.
(d) NPS must submit a comprehensive 5-year report covering all
activities conducted under the incidental take regulations at least 90
days prior to expiration of these regulations if new regulations are
sought or 90 days after expiration of regulations.
(e) Reporting of injured or dead marine mammals. (1) In the
unanticipated event that the activity defined in Sec. 219.20(a)
clearly causes the take of a marine mammal in a prohibited manner such
as an injury (Level A harassment), serious injury, or mortality, NPS
must immediately cease the specified activities and report the incident
to the Office of Protected Resources, NMFS, and the Alaska Regional
Stranding Coordinator, NMFS. The report must include the following
information:
(i) Time and date of the incident;
(ii) Description of the incident;
(iii) Environmental conditions (e.g., wind speed and direction,
Beaufort sea state, cloud cover, and visibility);
(iv) Description of all marine mammal observations and active sound
source use in the 24 hours preceding the incident;
(v) Species identification or description of the animal(s)
involved;
(vi) Fate of the animal(s); and
(vii) Photographs or video footage of the animal(s).
(2) Activities must not resume until NMFS is able to review the
circumstances of the prohibited take. NMFS will work with NPS to
determine what measures are necessary to minimize the likelihood of
further prohibited take and ensure MMPA compliance. NPS must not resume
their activities until notified by NMFS.
(3) In the event that NPS discovers an injured or dead marine
mammal, and the lead observer determines that the cause of the injury
or death is unknown and the death is relatively recent (e.g., in less
than a moderate state of decomposition), NPS must immediately report
the incident to the Office of Protected Resources, NMFS, and the Alaska
Stranding Coordinator, NMFS. The report must include the same
information identified in Sec. 217.25(e)(1). Activities may continue
while NMFS reviews the circumstances of the incident. NMFS will work
with NPS to determine whether additional mitigation measures or
modifications to the activities are appropriate.
(4) In the event that NPS discovers an injured or dead marine
mammal and determines that the injury or death is not associated with
or related to the activities defined in Sec. 217.20(a) (e.g.,
previously wounded animal, carcass with moderate to advanced
decomposition, scavenger damage), NPS must report the incident to OPR
and the Alaska Stranding Coordinator, NMFS, within 24 hours of the
discovery. NPS must provide photographs or video footage or other
documentation of the stranded animal sighting to NMFS. NPS can continue
their research activities.
(5) Pursuant to paragraphs Sec. 217.25(e)(2) through (4), NPS may
use discretion in determining what injuries (i.e., nature and severity)
are appropriate for reporting. At minimum, NPS must report those
injuries considered to be serious (i.e., will likely result in death)
or that are likely caused by human interaction (e.g., entanglement,
gunshot). Also pursuant to paragraphs Sec. 217.25(e)(3) and (4) of
this section, NPS may use discretion in determining the appropriate
vantage point for obtaining photographs of injured/dead marine mammals.
Sec. 217.26 Letters of Authorization.
(a) To incidentally take marine mammals pursuant to these
regulations, NPS must apply for and obtain an LOA.
(b) An LOA, unless suspended or revoked, may be effective for a
period of time not to exceed the expiration date of these regulations.
(c) If an LOA expires prior to the expiration date of these
regulations, NPS may apply for and obtain a renewal of the LOA.
(d) In the event of projected changes to the activity or to
mitigation and monitoring measures required by an LOA, NPS must apply
for and obtain a modification of the LOA as described in Sec. 217.27.
(e) The LOA shall set forth:
(1) Permissible methods of incidental taking;
(2) Means of effecting the least practicable adverse impact (i.e.,
mitigation) on the species, its habitat, and on the availability of the
species for subsistence uses; and
(3) Requirements for monitoring and reporting.
(f) Issuance of the LOA shall be based on a determination that the
level of taking will be consistent with the findings made for the total
taking allowable under these regulations.
(g) Notice of issuance or denial of an LOA shall be published in
the Federal Register within 30 days of a determination.
Sec. 217.27 Renewals and modifications of Letters of Authorization.
(a) An LOA issued under Sec. Sec. 216.106 of this chapter and
217.26 for the activity identified in Sec. 217.20(a) shall be renewed
or modified upon request by the applicant, provided that:
(1) The proposed specified activity and mitigation, monitoring, and
reporting measures, as well as the anticipated impacts, are the same as
those described and analyzed for these regulations (excluding changes
made pursuant to the adaptive management provision in paragraph (c)(1)
of this section), and
(2) NMFS determines that the mitigation, monitoring, and reporting
measures required by the previous LOA under these regulations were
implemented.
(b) For an LOA modification or renewal requests by the applicant
that include changes to the activity or the mitigation, monitoring, or
reporting (excluding changes made pursuant to the adaptive management
provision in paragraph (c)(1) of this section) that do not change the
findings made for the regulations or result in no more than a minor
change in the total estimated number of takes (or distribution by
species or years), NMFS may publish a notice of proposed LOA in the
Federal Register, including the associated analysis of the change, and
solicit public comment before issuing the LOA.
(c) An LOA issued under Sec. Sec. 216.106 of this chapter and
217.26 for the activity identified in Sec. 217.20(a) may be modified
by NMFS under the following circumstances:
(1) Adaptive Management--NMFS may modify (including augment) the
existing mitigation, monitoring, or reporting measures (after
consulting with NPS regarding the practicability of the modifications)
if doing so creates a reasonable likelihood of more effectively
accomplishing the goals of the mitigation and monitoring set forth in
the preamble for these regulations.
(i) Possible sources of data that could contribute to the decision
to modify the mitigation, monitoring, or reporting measures in an LOA:
(A) Results from NPS's monitoring from the previous year(s).
(B) Results from other marine mammal research or studies.
(C) Any information that reveals marine mammals may have been taken
in a manner, extent or number not authorized by these regulations or
subsequent LOAs.
(ii) If, through adaptive management, the modifications to the
mitigation, monitoring, or reporting measures are substantial, NMFS
shall publish a notice of proposed LOA in the Federal Register and
solicit public comment.
(2) Emergencies--If NMFS determines that an emergency exists that
poses a
[[Page 64096]]
significant risk to the well-being of the species or stocks of marine
mammals specified in LOAs issued pursuant to Sec. Sec. 216.106 of this
chapter and 217.26, an LOA may be modified without prior notice or
opportunity for public comment. Notice would be published in the
Federal Register within thirty days of the action.
