SUPPLEMENTARY INFORMATION:
Background
Section 101(a)(5)(D) of the Marine
Mammal Protection Act of 1972, as
amended (MMPA; 16 U.S.C. 1361 et
seq.) directs the Secretary of Commerce
to allow, upon request, the incidental,
PO 00000
Frm 00014
Fmt 4703
Sfmt 4703
but not intentional, taking of small
numbers of marine mammals of a
species or population stock, by United
States citizens who engage in a specified
activity (other than commercial fishing)
within a specified geographical region
if, after notice of a proposed
authorization to the public for review
and public comment: (1) We make
certain findings; and (2) the taking is
limited to harassment.
An authorization shall be granted for
the incidental taking of small numbers
of marine mammals if NMFS finds that
the taking will have a negligible impact
on the species or stock(s), and will not
have an unmitigable adverse impact on
the availability of the species or stock(s)
for subsistence uses (where relevant).
The authorization must also set forth the
permissible methods of taking; other
means of effecting the least practicable
adverse impact on the species or stock
and its habitat; and requirements
pertaining to the mitigation, monitoring
and reporting of such taking. NMFS has
defined ‘‘negligible impact’’ in 50 CFR
216.103 as ‘‘an impact resulting from
the specified activity that cannot be
reasonably expected to, and is not
reasonably likely to, adversely affect the
species or stock through effects on
annual rates of recruitment or survival.’’
Except with respect to certain
activities not pertinent here, the MMPA
defines ‘‘harassment’’ as: Any act of
pursuit, torment, or annoyance which (i)
has the potential to injure a marine
mammal or marine mammal stock in the
wild [Level A harassment]; or (ii) has
the potential to disturb a marine
mammal or marine mammal stock in the
wild by causing disruption of behavioral
patterns, including, but not limited to,
migration, breathing, nursing, breeding,
feeding, or sheltering [Level B
harassment].
Summary of Request
On December 14, 2013, NMFS
received an application from the Society
requesting that we issue an
Authorization for the take of marine
mammals, incidental to conducting
restoration activities on the St. George
Reef Light Station (Station) located on
Northwest Seal Rock offshore of
Crescent City, California in the
northeast Pacific Ocean. NMS
determined the application complete
and adequate on January 13, 2014.
The Society proposes to conduct
aircraft operations, lighthouse
renovation, and periodic maintenance
on the Station’s optical light system on
a monthly basis. The proposed activity
would occur on a monthly basis over
one weekend, April 1 through April 30,
2014 and November 1, 2014, through
E:\FR\FM\18FEN1.SGM
18FEN1
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
February 28, 2015. The following
specific aspects of the proposed
activities have the potential to take
marine mammals: (1) Helicopter
landings/takeoffs; (2) noise generated
during restoration activities (e.g.,
painting, plastering, welding, and
glazing); (3) maintenance activities (e.g.,
bulb replacement and automation of the
light system); and (4) human presence.
Thus, we anticipate that take, by Level
B harassment only, of California sea
lions (Zalophus californianus); Pacific
harbor seals (Phoca vitulina); Steller sea
lions (Eumetopias jubatus) of the
eastern U.S. Stock; and northern fur
seals (Callorhinus ursinus) could result
from the specified activity.
To date, we have issued four,
Authorizations to the Society for the
conduct of the same activities from 2010
to 2013 (75 FR 4774, January 29, 2010;
76 FR 10564, February 25, 2011; 77 FR
8811, February 15, 2012; and 79 FR
6179, February 3, 2014). This is the
Society’s fifth request for an annual
Authorization as their last
Authorization expired on December 31,
2013.
Description of the Specified Activity
Overview
The Station, listed in the National
Park Service’s National Register of
Historic Places, is located on Northwest
Seal Rock offshore of Crescent City,
California in the northeast Pacific
Ocean. The Station, built in 1892, rises
45.7 meters (m) (150 feet (ft)) above sea
level. The structure consists of
hundreds of granite blocks topped with
a cast iron lantern room and covers
much of the surface of the islet. The
purpose of the project is to restore the
lighthouse and to conduct annual and
emergency maintenance on the Station’s
optical light system.
tkelley on DSK3SPTVN1PROD with NOTICES
Dates and Duration
The Society proposes to conduct the
activities (aircraft operations, lighthouse
restoration, and maintenance activities)
from the period of April 1, 2014 through
March 31, 2015, at a maximum
frequency of one session per month. The
proposed duration for each session
would last no more than three days (e.g.,
Friday, Saturday, and Sunday). The
proposed Authorization, if issued,
would be effective from April 1, 2014
through April 30, 2014 and November 1,
2014, through March 31, 2015.
We refer the reader to the Detailed
Description of Activities section later in
this notice for more information on the
scope of the proposed activities.
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
Specified Geographic Region
The Station is located on a small,
rocky islet (41°50′24″ N, 124°22′06″ W)
approximately nine kilometers (km) (6.0
miles (mi)) in the northeast Pacific
Ocean, offshore of Crescent City,
California (Latitude: 41°46′48″ N;
Longitude: 124°14′11″ W). NWSR is
approximately 91.4 m (300 ft) in
diameter that peaks at 5.18 m (17 ft)
above mean sea level.
Detailed Description of Activities
Aircraft Operations
Because Northwest Seal Rock has no
safe landing area for boats, the proposed
restoration activities would require the
Society to transport personnel and
equipment from the California mainland
to Northwest Seal Rock by a small
helicopter. Helicopter landings take
place on top of the engine room
(caisson) which is approximately 15 m
(48 ft) above the surface of the rocks on
Northwest Seal Rock. The Society plans
to charter a Raven R44 helicopter,
owned and operated by Air Shasta Rotor
and Wing, LLC. The Raven R44, which
seats three passengers and one pilot, is
a compact-sized (1134 kilograms (kg),
2500 pounds (lbs)) helicopter with twobladed main and tail rotors. Both sets of
rotors are fitted with noise-attenuating
blade tip caps that would decrease
flyover noise.
The Society proposes to transport no
more than 15 work crew members and
equipment to Northwest Seal Rock for
each session and estimates that each
session would require no more than 36
helicopter landings/takeoffs per month.
During landing, the helicopter would
land on the caisson to allow the work
crew members to disembark and retrieve
their equipment located in a basket
attached to the underside of the
helicopter. The helicopter would then
return to the mainland to pick up
additional personnel and equipment.
Proposed schedule: The Society
would conduct a maximum of 16 flights
(eight arrivals and eight departures) for
the first day. The first flight would
depart from Crescent City Airport at
approximately 9 a.m. for a 6-minute
flight to Northwest Seal Rock. The
helicopter would land and takeoff
immediately after offloading personnel
and equipment every 20 minutes (min).
The total duration of the first day’s
aerial operations could last for
approximately 3 hours (hrs) and 26 min
and would end at approximately 12:34
p.m. Crew members would remain
overnight at the Station and would not
return to the mainland on the first day.
For the second day, the Society would
conduct a maximum of 10 flights (five

9171
arrivals and five departures) to transport
additional materials on and off the islet.
The first flight would depart from
Crescent City Airport at 9 a.m. for a 6minute flight to Northwest Seal Rock.
The total duration of the second day’s
aerial operations could last up to three
hours.
For the final day of operations, the
Society could conduct a maximum of
eight helicopter flights (four arrivals and
four departures) to transport the
remaining crew members and
equipment/material back to the Crescent
City Airport. The total duration of the
third day’s helicopter operations in
support of restoration could last up to
2 hrs and 14 min.
Lighthouse Restoration Activities
Restoration and maintenance
activities would involve the removal of
peeling paint and plaster, restoration of
interior plaster and paint, refurbishing
structural and decorative metal,
reworking original metal support beams
throughout the lantern room and
elsewhere, replacing glass as necessary,
upgrading the present electrical system;
and annual light beacon maintenance.
Light Maintenance Activities
The Society will need to conduct
maintenance on the Station’s beacon
light at least once or up to two times per
year within the proposed work window.
Scheduled light maintenance activities
would coincide with lighthouse
restoration activities conducted monthly
during the period of April 1 through
April 30, 2014 and during the period of
November 1, 2014, through March 31,
2015. The Society expects that
maintenance activities would not
exceed 3 hrs per each monthly session.
Emergency Light Maintenance
If the beacon light fails during the
period from April 1 through April 30,
2014 or November 1, 2014 through
March 31, 2015, the Society proposes to
send a crew of two to three people to the
Station by helicopter to repair the
beacon light. For each emergency repair
event, the Society proposes to conduct
a maximum of four flights (two arrivals
and two departures) to transport
equipment and supplies. The helicopter
may remain on site or transit back to
shore and make a second landing to
pick up the repair personnel.
In the case of an emergency repair
between May 1, 2014, and October 31,
2014, the Society would consult with
the NMFS’ Western Regional Office
(WRO) biologists to best determine the
timing of the trips to the lighthouse, on
a case-by-case basis, based upon the
existing environmental conditions and
E:\FR\FM\18FEN1.SGM
18FEN1
9172
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
the abundance and distribution of any
marine mammals present on NWSR.
The regional biologists would have realtime knowledge regarding the animal
use and abundance of the NWSR at the
time of the repair request and would
make a decision regarding when the
Society could conduct trips to the
lighthouse during the emergency repair
time window that would have the least
practicable adverse impact to marine
mammals. The WRO biologists would
also ensure that the Society’s request for
incidental take during emergency
repairs would not exceed the number of
incidental take authorized in the
proposed Authorization. To date, the
Society has not needed to conduct
emergency light maintenance between
May through October under any of the
four previous Authorizations.
Sound Sources and Sound
Characteristics
NMFS expects that acoustic stimuli
resulting from the proposed helicopter
operations; noise from maintenance and
restoration activities; and human
presence have the potential to harass
marine mammals, incidental to the
conduct of the proposed activities.
This section includes a brief
explanation of the sound measurements
frequently used in the discussions of
acoustic effects in this notice. Sound
pressure is the sound force per unit
area, and is usually measured in
micropascals (mPa), where 1 pascal (Pa)
is the pressure resulting from a force of
one newton exerted over an area of one
square meter. Sound pressure level
(SPL) is the ratio of a measured sound
pressure and a reference level. The
commonly used reference pressure is 1
mPa for under water, and the units for
SPLs are dB re: 1 mPa. The commonly
used reference pressure is 20 mPa for in
air, and the units for SPLs are dB re: 20
mPa.
SPL (in decibels (dB)) = 20 log
(pressure/reference pressure).
SPL is an instantaneous measurement
expressed as the peak, the peak-peak (pp), or the root mean square (rms). Root
mean square is the square root of the
arithmetic average of the squared
instantaneous pressure values. All
references to SPL in this document refer
to the root mean square unless
otherwise noted. SPL does not take into
account the duration of a sound.
R44 Helicopter Sound Characteristics
Noise testing performed on the R44
Raven Helicopter, as required for
Federal Aviation Administration
approval, required an overflight at 150
m (492 ft) above ground level, 109 knots
and a maximum gross weight of 1,134
kg (2,500 lbs). The noise levels
measured on the ground at this distance
and speed were 81.9 decibels (dB) re: 20
mPa (A-weighted) for the model R44
Raven I, or 81.0 dB re: 20 mPa (Aweighted) for the model R44 Raven II
(NMFS, 2007).
Based on this information, we expect
that the received sound levels at the
landing area on the Station’s caisson
would increase above 81–81.9 dB re: 20
mPa (A-weighted).
Restoration and Maintenance Sound
Characteristics
Any noise associated with these
activities is likely to be from light
construction (e.g., sanding, hammering,
or use of hand drills). The Society
proposes to confine all restoration
activities to the existing structure which
would occur on the upper levels of the
Station. Pinnipeds hauled out on
Northwest Seal Rock do not have access
to the upper levels of the Station.

The marine mammals most likely to
be harassed incidental to the Society’s
helicopter operations, lighthouse
restoration, and lighthouse maintenance
on Northwest Seal Rock are primarily
Steller and California sea lions and to a
lesser extent the Pacific harbor seal and
the eastern Pacific stock of northern fur
seal. We refer the public to Carretta et
al., (2013) and Allen and Angliss (2013)
for general information on these species
which we present in this notice. The
publications are available at https://
www.nmfs.noaa.gov/pr/sars/region.htm.
We present a summary of information
on these species below this section.
California Sea Lion
The California sea lion is now a full
species, separated from the Galapagos
sea lion (Z. wollebaeki) and the extinct
Japanese sea lion (Z. japonicus)
(Brunner 2003, Wolf et al., 2007,
Schramm et al., 2009). The estimated
population of the U.S. stock of
California sea lion is approximately
296,750 animals and the current
maximum population growth rate is 12
percent (Carretta et al., 2013).
California sea lion breeding areas are
on islands located in southern
California, in western Baja California,
Mexico, and the Gulf of California.
During the breeding season, most
California sea lions inhabit southern
California and Mexico. Rookery sites in
southern California are limited to the
San Miguel Islands and the southerly
Channel Islands of San Nicolas, Santa
Barbara, and San Clemente (Carretta et
al., 2013). Males establish breeding
territories during May through July on
both land and in the water. Females
come ashore in mid-May and June
where they give birth to a single pup
approximately four to five days after
arrival and will nurse pups for about a
week before going on their first feeding
trip. Females will alternate feeding trips
with nursing bouts until weaning
between four and 10 months of age
(NMML, 2010).
Adult and juvenile males will migrate
as far north as British Columbia, Canada
while females and pups remain in
southern California waters in the nonbreeding season. In warm water (El
˜
Nino) years, some females range as far
north as Washington and Oregon,
presumably following prey.
Crescent Coastal Research (CCR)
conducted a three-year (1998–2000)
survey of the wildlife species on NWSR
for the Society. They reported that
counts of California sea lions on NWSR
varied greatly (from six to 541) during
the observation period from April 1997
through July 2000. CCR reported that
counts for California sea lions during
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
the spring (April—May), summer (June–
August), and fall (September–October),
averaged 60, 154, and 235, respectively
(CCR, 2001).
The most current counts for the
month of July by NMFS (2000 through
2004) have been relatively low as the
total number of California sea lions
recorded in 2000 and 2003 was 3 and
11, respectively (M. Lowry, NMFS,
SWFSC, unpublished data). Based on
the monitoring report for the 2011
season, the maximum numbers of
California sea lions present during the
April and November, 2011 work
sessions was 2 and 90 animals,
respectively (SGRLPS, 2012). There
were no California sea lions present
during the March, 2012 work session
(SGRLPS, 2012).
Northern Fur Seal
Northern fur seals occur from
southern California north to the Bering
Sea and west to the Sea of Okhotsk and
Honshu Island of Japan. NMFS
recognizes two separate stocks of
northern fur seals within U.S. waters:
An Eastern Pacific stock distributed
among sites in Alaska, British Columbia;
and a San Miguel Island stock
distributed along the west coast of the
continental U.S. The estimated
population of the San Miguel Island
stock is 9,968 animals with a maximum
population growth rate of 12 percent
(Carretta et al., 2013).
Northern fur seals may temporarily
haul out on land at other sites in Alaska,
British Columbia, and on islets along
the west coast of the continental United
States, but generally this occurs outside
of the breeding season (Fiscus, 1983).
Northern fur seals breed in Alaska
and migrate along the west coast during
fall and winter. Due to their pelagic
habitat, they are rarely seen from shore
in the continental U.S., but individuals
occasionally come ashore on islands
well offshore (i.e., Farallon Islands and
Channel Islands in California). During
the breeding season, approximately 74
percent of the worldwide population
inhabits the Pribilof Islands in Alaska,
with the remaining animals spread
throughout the North Pacific Ocean
(Lander and Kajimura, 1982).
CCR observed one male northern fur
seal on Northwest Seal Rock in October,
1998 (CCR, 2001). It is possible that a
few animals may use the island more
often that indicated by the CCR surveys,
if they were mistaken for other otariid
species (i.e., eared seals or fur seals and
sea lions) (M. DeAngelis, NMFS, pers.
comm.).
For the 2010, 2011, and 2012 work
seasons, the Society has not observed
any northern fur seals present on
PO 00000
Frm 00017
Fmt 4703
Sfmt 4703
9173
Northwest Seal Rock during restoration
activities (SGRLPS, 2010; 2011; 2012).
The Society did not conduct any
operations for the 2013 season.
Pacific Harbor Seal
The estimated population of the
California stock of Pacific harbor seals is
approximately 30,196 animals (Carretta
et al., 2013). There is no current
estimate of abundance available for the
Oregon/Washington stock (Carretta et
al., 2013).
The animals inhabit near-shore
coastal and estuarine areas from Baja
California, Mexico, to the Pribilof
Islands in Alaska. Pacific harbor seals
consist of two subspecies: P. v.
stejnegeri in the western North Pacific,
near Japan, and P. v. richardsi in the
northeast Pacific Ocean. The latter
subspecies, recognized as three separate
stocks, inhabits the west coast of the
continental United States, including:
The outer coastal waters of Oregon and
Washington states; Washington state
inland waters; and Alaska coastal and
inland waters. Two of these stocks, the
California stock and Oregon/
Washington coast stock, of Pacific
harbor seals are identified off the coast
of Oregon and California for
management purposes under the
MMPA. However, the stock boundary is
difficult to distinguish because of the
continuous distribution of harbor seals
along the west coast and any rigid
boundary line is (to a greater or lesser
extent) arbitrary, from a biological
perspective (Carretta et al., 2011). Due
to the location of the proposed project
which is situated near the border of
Oregon and California, both stocks
could be present within the proposed
project area.
In California, over 500 harbor seal
haulout sites are widely distributed
along the mainland and offshore
islands, and include rocky shores,
beaches and intertidal sandbars (Lowry
et al., 2005). Harbor seals mate at sea
and females give birth during the spring
and summer, although, the pupping
season varies with latitude. Females
nurse their pups for an average of 24
days and are ready to swim minutes
after being born. Harbor seal pupping
takes place at many locations and
rookery size varies from a few pups to
many hundreds of pups. The nearest
harbor seal rookery relative to the
proposed project site is at Castle Rock
National Wildlife Refuge, located
approximately located 965 m (0.6 mi)
south of Point St. George, and 2.4 km
(1.5 mi) north of the Crescent City
Harbor in Del Norte County, California
(USFWS, 2007).

CCR noted that harbor seal use of
Northwest Seal Rock was minimal, with
only one sighting of a group of six
animals, during 20 observation surveys.
They hypothesized that harbor seals
may avoid the islet because of its
distance from shore, relatively steep
topography, and full exposure to rough
and frequently turbulent sea swells. For
the 2010 and 2011 seasons, the Society
did not observe any Pacific harbor seals
present on Northwest Seal Rock during
restoration activities (SGRLPS, 2010;
2011). During the 2012 season, the
Society reported sighting a total of two
harbor seals present on Northwest Seal
Rock (SGRLPS, 2012). The Society did
not conduct any operations for the 2013
season.
Steller Sea Lion
Steller sea lions consist of two
distinct population segments: the
western and eastern distinct population
segments (DPS) divided at 144° West
longitude (Cape Suckling, Alaska). The
western segment of Steller sea lions
inhabit central and western Gulf of
Alaska, Aleutian Islands, as well as
coastal waters and breed in Asia (e.g.,
Japan and Russia). The eastern segment
includes sea lions living in southeast
Alaska, British Columbia, California,
and Oregon.
Steller sea lions range along the North
Pacific Rim from northern Japan to
California (Loughlin et al., 1984), with
centers of abundance and distribution in
the Gulf of Alaska and Aleutian Islands,
respectively. The species is not known
to migrate, but individuals disperse
widely outside of the breeding season
(late May through early July), thus
potentially intermixing with animals
from other areas.
In 2012, the estimated population of
the eastern distinct population segment
ranged from a minimum of 58,334 up to
72,223 animals and the maximum
population growth rate is 12 percent
(Allen and Angliss, 2013). On October
23, 2013 NMFS announced the removal
of the eastern distinct population
segment of Steller sea lions from the list
of threatened species under the ESA. As
of December 4, 2013 the eastern DPS is
not a threatened species listed under the
ESA. With the delisting, federal
agencies proposing actions that may
affect the eastern Steller sea lions are no
longer required to consult with NMFS
under section 7 of the ESA.
The eastern distinct population
segment of Steller sea lions breeds on
rookeries located in southeast Alaska,
British Columbia, Oregon, and
California. There are no rookeries
located in Washington state. Steller sea
lions give birth in May through July and
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
breeding commences a couple of weeks
after birth. Pups are weaned during the
winter and spring of the following year.
Despite the wide-ranging movements
of juveniles and adult males in
particular, exchange between rookeries
by breeding adult females and males
(other than between adjoining rookeries)
appears low, although males have a
higher tendency to disperse than
females (NMFS, 1995; Trujillo et al.,
2004; Hoffman et al., 2006). A
northward shift in the overall breeding
distribution has occurred, with a
contraction of the range in southern
California and new rookeries
established in southeastern Alaska
(Pitcher et al., 2007). Overall, counts of
non-pups at trend sites in California and
Oregon have been relatively stable or
increasing slowly since the 1980s (Allen
and Angliss, 2012).
CCR reported that Steller sea lion
numbers at Northwest Seal Rock ranged
from 20 to 355 animals. Counts of
Steller sea lions during the spring
(April—May), summer (June–August),
and fall (September–October), averaged
68, 110, and 56, respectively (CCR,
2001). A more recent survey at NWSR
between 2000 and 2004 showed Steller
sea lion numbers ranged from 175 to
354 in July (M. Lowry, NMFS/SWFSC,
unpubl. data). The Society presumes
that winter use of NWSR by Steller sea
lion to be minimal, due to inundation of
the natural portion of the island by large
swells.
For the 2010 season, the Society
reported that no Steller sea lions were
present in the vicinity of Northwest Seal
Rock during restoration activities
(SGRLPS, 2010). Based on the
monitoring report for the 2011 season,
the maximum numbers of Steller sea
lions present during the April and
November 2011, work sessions was 2
and 150 animals, respectively (SGRLPS,
2012). During the 2012 season, the
Society did not observe any Steller sea
lions present on Northwest Seal Rock
during restoration activities. The
Society did not conduct any operations
for the 2013 season.
Potential Effects of the Specified
Activities on Marine Mammals
This section includes a summary and
discussion of the ways that the types of
stressors associated with the specified
activity (e.g., aircraft operations and
human presence) have the potential to
impact marine mammals. This
discussion may also include reactions
that we consider to rise to the level of
a take and those that we do not consider
to rise to the level of a take (e.g., with
acoustics, we may include a discussion
of studies that show animals not
PO 00000

reacting to sound or animals exhibiting
barely perceptible avoidance behaviors).
We also intend this section to provide
a background of potential effects of the
Society’s activities. This section does
not consider the specific manner in
which the Society would carry out the
proposed activity, what mitigation
measures the Society would implement,
and how either of those would shape
the anticipated impacts from this
specific activity. The ‘‘Estimated Take
by Incidental Harassment’’ section later
in this document will include a
quantitative analysis of the number of
individuals that we expect the Society
to take during this activity. The
‘‘Negligible Impact Analysis’’ section
will include the analysis of how this
specific activity would impact marine
mammals. We will consider the content
of the following sections: (1) Negligible
Impact Analysis; (2) Estimated Take by
Incidental Harassment; (3) Proposed
Mitigation; and (4) Anticipated Effects
on Marine Mammal Habitat, to draw
conclusions regarding the likely impacts
of the Society’s activities on the
reproductive success or survivorship of
individuals—and from that
consideration—the likely impacts of this
activity on the affected marine mammal
populations or stocks.
Acoustic Impacts
Acoustic and visual stimuli generated
by: (1) Helicopter landings/takeoffs; (2)
noise generated during restoration
activities (e.g., painting, plastering,
welding, and glazing); and (3)
maintenance activities (e.g., bulb
replacement and automation of the light
system) may have the potential to cause
the following: temporary or permanent
hearing impairment and/or behavioral
disturbance (Southall, et al., 2007).
When considering the influence of
various kinds of sound on the marine
environment, it is necessary to
understand that different kinds of
marine life are sensitive to different
frequencies of sound and current data
indicate that not all marine mammal
species have equal hearing capabilities
(Richardson et al., 1995; Wartzok and
Ketten, 1999). Southall et al. (2007)
designated ‘‘functional hearing groups’’
for marine mammals based on available
behavioral data; audiograms derived
from auditory evoked potentials;
anatomical modeling; and other data.
Southall et al. (2007) also estimated the
lower and upper frequencies of
functional hearing for each group as
animals are less sensitive to sounds at
the lower and upper frequency limits of
their functional hearing range and are
more sensitive to a range of frequencies

Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
tkelley on DSK3SPTVN1PROD with NOTICES
within the middle of their functional
hearing range.
The functional groups and the
associated frequencies are:
• Low frequency cetaceans (13
species of mysticetes): functional
hearing estimates occur between
approximately 7 Hertz (Hz) and 30 kHz
(extended from 22 kHz based on data
indicating that some mysticetes can hear
above 22 kHz; Au et al., 2006; Lucifredi
and Stein, 2007; Ketten and Mountain,
2009; Tubelli et al., 2012);
• Mid-frequency cetaceans (32
species of dolphins, six species of larger
toothed whales, and 19 species of
beaked and bottlenose whales):
functional hearing estimates occur
between approximately 150 Hz and 160
kHz;
• High-frequency cetaceans (eight
species of true porpoises, six species of
river dolphins, Kogia, the franciscana,
and four species of cephalorhynchids):
functional hearing estimates occur
between approximately 200 Hz and 180
kHz; and
• Pinnipeds in water: functional
hearing estimates occur between
approximately 75 Hz and 100 kHz, with
the greatest sensitivity between
approximately 700 Hz and 20 kHz.
As mentioned previously in this
document, four marine mammal species
would likely occur in the proposed
action area. All are pinnipeds and fall
under the Pinnipeds in water functional
hearing group category. We consider a
species’ functional hearing group when
we analyze the effects of exposure to
sound on marine mammals.
Helicopter Noise
Marine mammals produce sounds in
various important contexts—social
interactions, foraging, navigating, and to
responding to predators. The best
available science suggests that
pinnipeds have a functional aerial
hearing sensitivity between 75 hertz
(Hz) and 75 kilohertz (kHz) and can
produce a diversity of sounds, though
generally from 100 Hz to several tens of
kHz (Southall, et al., 2007).
Exposure to high intensity sound for
a sufficient duration may result in
auditory effects such as a noise-induced
threshold shift—an increase in the
auditory threshold after exposure to
noise (Finneran, Carder, Schlundt, and
Ridgway, 2005). Factors that influence
the amount of threshold shift include
the amplitude, duration, frequency
content, temporal pattern, and energy
distribution of noise exposure. The
magnitude of hearing threshold shift
normally decreases over time following
cessation of the noise exposure. The
amount of threshold shift just after
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
exposure is called the initial threshold
shift. If the threshold shift eventually
returns to zero (i.e., the threshold
returns to the pre-exposure value), it is
called temporary threshold shift (TTS)
(Southall et al., 2007).
Pinnipeds have the potential to be
disturbed by airborne and underwater
noise generated by the engine of the
aircraft (Born, Riget, Dietz, &
Andriashek, 1999; Richardson, Greene,
Malme, & Thomson, 1995). Data on
underwater TTS-onset in pinnipeds
exposed to pulses are limited to a single
study which exposed two California sea
lions to single underwater pulses from
an arc-gap transducer and found no
measurable TTS following exposures up
to 183 dB re: 1 mPa (peak-to-peak)
(Finneran, Dear, Carder, & Ridgway,
2003).
Researchers have demonstrated TTS
in certain captive odontocetes and
pinnipeds exposed to strong sounds
(reviewed in Southall et al., 2007). In
2004, researchers measured auditory
fatigue to airborne sound in harbor
seals, California sea lions, and northern
elephant seals after exposure to nonpulse noise for 25 minutes (Kastak,
Southall, Holt, Kastak, & Schusterman,
2004). In the study, the harbor seal
experienced approximately 6 dB of TTS
at 99 dB re: 20 mPa. The authors
identified onset of TTS in the California
sea lion at 122 dB re: 20 mPa. The
northern elephant seal experienced
TTS-onset at 121 dB re: 20 mPa (Kastak,
et al., 2004).
There is a dearth of information on
acoustic effects of helicopter overflights
on pinniped hearing and
communication (Richardson, et al.,
1995) and to NMFS’ knowledge, there
has been no specific documentation of
TTS, let alone permanent threshold shift
(PTS), in free-ranging pinnipeds
exposed to helicopter operations during
realistic field conditions (Baker, Jensz, &
Chilvers, 2012; Scheidat et al., 2011).
In 2008, we issued an Authorization
to the USFWS for the take of small
numbers of Steller sea lions and Pacific
harbor seals, incidental to rodent
eradication activities on an islet offshore
of Rat Island, AK conducted by
helicopter. The 15-minute aerial
treatment consisted of the helicopter
slowly approaching the islet at an
elevation of over 1,000 feet (304.8 m);
gradually decreasing altitude in slow
circles; and applying the rodenticide in
a single pass and returning to Rat Island.
The gradual and deliberate approach to
the islet resulted in the sea lions present
initially becoming aware of the
helicopter and calmly moving into the
water. Further, the USFWS reported that
all responses fell well within the range
PO 00000
Frm 00019
Fmt 4703
Sfmt 4703
9175
of Level B harassment (i.e., alert head
raises without moving or limited, shortterm displacement resulting from
aircraft noise due to helicopter
overflights).
As a general statement from the
available information, pinnipeds
exposed to intense (approximately 110
to 120 dB re: 20 mPa) non-pulse sounds
often leave haulout areas and seek
refuge temporarily (minutes to a few
hours) in the water (Southall et al.,
2007). Any noise attributed to the
Society’s proposed helicopter
operations on NWSR would be shortterm (approximately 5 min per trip). We
would expect the ambient noise levels
to return to a baseline state when
helicopter operations have ceased for
the day. Per Richardson et al. (1995),
approaching aircraft generally flush
animals into the water and noise from
a helicopter is typically directed down
in a ‘‘cone’’ underneath the aircraft. As
the helicopter landings take place 15 m
(48 ft) above the surface of the rocks on
NWSR, we presume that the received
sound levels would increase above 81–
81.9 dB re: 20 mPa (A-weighted) at the
landing pad. However, we do not expect
that the increased received levels of
sound from the helicopter would cause
TTS or PTS because the pinnipeds
would flush before the helicopter
approached NWSR; thus increasing the
distance between the pinnipeds and the
received sound levels on NWSR during
the proposed action.
Visual Disturbance
There is increasing recognition that
the effect of human disturbance wildlife
is highly dependent on the nature of the
disturbance (Burger et al., 1995; Klein et
al., 1995; and Kucey, 2005).
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; Mortenson et al., 2000;
and Kucey and Trites, 2006). The
apparent skittishness of both harbor
seals and Steller sea lions raises
concerns regarding behavioral and
physiological impacts to individuals
and populations experiencing high
levels of human disturbance. Human
activity can flush harbor seals off haul
out sites (Allen et al., 1984;
Calambokidis et al., 1991; Suryan and
Harvey, 1999; Mortenson et al., 2000).
The Hawaiian monk seal (Monachus
schauinslandi) may avoid beaches
disturbed by humans (Kenyon, 1972).
Stevens and Boness (2003) concluded
˜
that after the 1997–98 El Nino, when
populations of the South American fur

seal, Arctocephalus australis, in Peru
declined dramatically, seals abandoned
some of their former primary breeding
sites, but continued to breed at adjacent
beaches that were more rugged (i.e., less
likely to be used by humans).
Abandoned and unused sites were more
likely to have human disturbance than
currently used sites. In one case, human
disturbance appeared to cause Steller
sea lions to desert a breeding area at
Northeast Point on St. Paul Island,
Alaska (Kenyon, 1962).
It is likely that the initial helicopter
approach to the Station would cause a
subset, or all of the marine mammals
hauled out on NWSR to depart the rock
and flush into the water. The physical
presence of aircraft could also lead to
non-auditory effects on marine
mammals involving visual or other cues.
Airborne sound from a low-flying
helicopter or airplane may be heard by
marine mammals while at the surface or
underwater. In general, helicopters tend
to be noisier than fixed wing aircraft of
similar size and underwater sounds
from aircraft are strongest just below the
surface and directly under the aircraft.
Noise from aircraft would not be
expected to cause direct physical effects
but have the potential to affect behavior.
The primary factor that may influence
abrupt movements of animals is engine
noise, specifically changes in engine
noise. Responses by mammals could
include hasty dives or turns, change in
course, or flushing and stampeding from
a haul out site. There are few well
documented studies of the impacts of
aircraft overflight over pinniped haul
out sites or rookeries, and many of those
that exist, are specific to military
activities (Efroymson et al., 2001).
Several factors complicate the
analysis of long- and short-term effects
for aircraft overflights. Information on
behavioral effects of overflights by
military aircraft (or component
stressors) on most wildlife species is
sparse. Moreover, models that relate
behavioral changes to abundance or
reproduction, and those that relate
behavioral or hearing effects thresholds
from one population to another are
generally not available. In addition, the
aggregation of sound frequencies,
durations, and the view of the aircraft
into a single exposure metric is not
always the best predictor of effects and
it may also be difficult to calculate.
Overall, there has been no indication
that single or occasional aircraft flying
above pinnipeds in water cause long
term displacement of these animals
(Richardson et al., 1995). The Lowest
Observed Adverse Effects Levels
(LOAELs) are rather variable for
pinnipeds on land, ranging from just
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
over 150 m (492 ft) to about 2,000 m
(6,562 ft) (Efroymson et al., 2001). A
conservative (90th percentile) distance
effects level is 1,150 m (3,773 ft). Most
thresholds represent movement away
from the overflight. Bowles and Stewart
(1980) estimated an LOAEL of 305 m
(1,000 ft) for helicopters (low and
landing) in California sea lions and
harbor seals observed on San Miguel
Island, CA; animals responded to some
degree by moving within the haul out
and entering into the water, stampeding
into the water, or clearing the haul out
completely. Both species always
responded with the raising of their
heads. California sea lions appeared to
react more to the visual cue of the
helicopter than the noise.
If pinnipeds are present on NWSR, it
is likely that a helicopter landing at the
Station would cause some number of
the pinnipeds on NWSR to flush;
however, when present, they appear to
show rapid habituation to helicopter
landing and departure (Crescent Coastal
Research, 2001; Guy Towers, SGRLPS,
pers. com.). According to the CCR
Report (2001), while up to 40 percent of
the California and Steller sea lions
present on the rock have been observed
to enter the water on the first of a series
of helicopter landings, as few as zero
percent have flushed on subsequent
landings on the same date. In fact, the
Society reported that during the
November 2011 work session, Steller
sea lions and California sea lions
exhibited minimal ingress and egress
from Northwest Seal Rock during
helicopter approaches and departures
(SGRLPS, 2011).
If pinnipeds are present on NWSR,
Level B behavioral harassment of
pinnipeds may occur during helicopter
landing and takeoff from NWSR due to
the pinnipeds temporarily moving from
the rocks and lower structure of the
Station into the sea due to the noise and
appearance of helicopter during
approaches and departures. It is
expected that all or a portion of the
marine mammals hauled out on the
island will depart the rock and move
into the water upon initial helicopter
approaches. The movement to the water
would be gradual due to the required
controlled helicopter approaches (see
Proposed Mitigation section), the small
size of the aircraft, the use of noiseattenuating blade tip caps on the rotors,
and behavioral habituation on the part
of the animals as helicopter trips
continue throughout the day. During the
sessions of helicopter activity, if present
on NWSR, some animals may be
temporarily displaced from the island
and either raft in the water or relocate
to other haul-outs.

Sfmt 4703
Sea lions have shown habituation to
helicopter flights within a day at the
project site and most animals are
expected to return soon after helicopter
activities cease for that day. By
clustering helicopter arrival/departures
within a short time period, we expect
animals present to show less response to
subsequent landings. We anticipate no
impact on the population size or
breeding stock of Steller sea lions,
California sea lions, Pacific harbor seals,
or northern fur seals.
Restoration and maintenance
activities would involve the removal of
peeling paint and plaster, restoration of
interior plaster and paint, refurbishing
structural and decorative metal,
reworking original metal support beams
throughout the lantern room and
elsewhere, replacing glass as necessary,
upgrading the present electrical system;
and annual light beacon maintenance.
Any noise associated with these
activities is likely to be from light
construction (e.g., sanding, hammering,
or use of hand drills) and the pinnipeds
may be disturbed by human presence.
Animals respond to disturbance from
humans in the same way as they
respond to the risk of predation, by
avoiding areas of high risk, either
completely or by using them for limited
periods (Gill et al., 1996).
Stampede
Sudden movement of large numbers
of animals may cause a stampede. In
order to prevent such stampedes from
occurring within the sea lion colony, we
would require certain mitigation
requirements and restrictions, such as
controlled helicopter approaches and
limited access period during the
pupping season, should we issue an
Authorization. As such, and because
any pinnipeds nearby likely would
avoid the approaching helicopter, the
Society anticipates that there will be no
instances of injury or mortality during
the proposed project.
Anticipated Effects on Marine Mammal
Habitat
NMFS does not expect that the
proposed activity would have any
effects on marine mammal habitat.
Based on previous monitoring reports
and anecdotal observations, up to 315
animals could use the small, rocky base
at the base of the Station as a haulout
site. The Society proposes to confine all
restoration activities to the existing
structure which would occur on the
upper levels of the Station which are
not used by marine mammals. Thus,
NMFS expects that there will be no
long- or short-term physical impacts to
pinniped habitat on NWSR.
E:\FR\FM\18FEN1.SGM
18FEN1
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
tkelley on DSK3SPTVN1PROD with NOTICES
The Society would remove all waste,
discarded materials and equipment from
the island after each visit. The proposed
activities will not result in any
permanent impact on habitats used by
marine mammals, including prey
species and foraging habitat. The main
impact associated with the proposed
activity will be temporarily elevated
noise levels and the associated direct
effects on marine mammals (i.e., the
potential for temporary abandonment of
the site), previously discussed in this
notice.
Proposed Mitigation
In order to issue an incidental take
authorization under section 101(a)(5)(D)
of the MMPA, NMFS must set forth the
permissible methods of taking pursuant
to such activity, and other means of
effecting the least practicable adverse
impact on such species or stock and its
habitat, paying particular attention to
rookeries, mating grounds, and areas of
similar significance, and on the
availability of such species or stock for
taking for certain subsistence uses
(where relevant).
As a way to reduce or minimize
adverse impacts that would result from
the proposed project to the lowest level
practicable, NMFS proposes to require
the following mitigation measures.
Time and Frequency: The Society
would conduct restoration activities at
maximum of once per month between
April 1 through April 30, 2014 and
November 1, 2014, through March 31,
2015. Each restoration session would
last no more than three days.
Maintenance of the light beacon would
occur only in conjunction with
restoration activities.
Helicopter Approach and Timing
Techniques: The Society would ensure
that its helicopter approach patterns to
the Station and timing techniques do
not disturb marine mammals as most
practicable. To the extent possible, the
helicopter should approach NWSR
when the tide is too high for the marine
mammals to haul-out on NWSR.
Since the most severe impacts
(stampede) precede rapid and direct
helicopter approaches, the Society’s
initial approach to the Station must be
offshore from the island at a relatively
high altitude (e.g., 800–1,000 ft, or 244–
305 m). Before the final approach, the
helicopter shall circle lower, and
approach from area with the lowest
pinniped density. If for any safety
reasons (e.g., wind condition) the
Society cannot conduct these types of
helicopter approach and timing
techniques, they must abort the
restoration and maintenance activities
for that day.
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
Avoidance of Visual and Acoustic
Contact with People on Island: The
Society would instruct its members and
restoration crews to avoid making
unnecessary noise and not expose
themselves visually to pinnipeds
around the base of the Station. Although
CCR reported no impacts from these
activities in the 2001 CCR study, it is
relatively simple for the Society to avoid
this potential impact. The door to the
lower platform (which is used at times
by pinnipeds) shall remain closed and
barricaded to all tourists and other
personnel.
Mitigation Conclusions
NMFS has carefully evaluated the
Society’s proposed mitigation measures
in the context of ensuring that we
prescribe the means of effecting the least
practicable impact on the affected
marine mammal species and stocks and
their habitat. Our evaluation of potential
measures included consideration of the
following factors in relation to one
another:
• The manner in which, and the
degree to which, the successful
implementation of the measure is
expected to minimize adverse impacts
to marine mammals;
• The proven or likely efficacy of the
specific measure to minimize adverse
impacts as planned; and
• The practicability of the measure
for applicant implementation.
Any mitigation measure(s) prescribed
by us should be able to accomplish,
have a reasonable likelihood of
accomplishing (based on current
science), or contribute to the
accomplishment of one or more of the
general goals listed here:
1. Avoidance or minimization of
injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may
contribute to this goal).
2. A reduction in the numbers of
marine mammals (total number or
number at biologically important time
or location) exposed to helicopter
operations and human presence that we
expect to result in the take of marine
mammals (this goal may contribute to 1,
above, or to reducing harassment takes
only).
3. A reduction in the number of times
(total number or number at biologically
important time or location) individuals
would be exposed to helicopter
operations or human presence that we
expect to result in the take of marine
mammals (this goal may contribute to 1,
above, or to reducing harassment takes
only).
4. A reduction in the intensity of
exposures (either total number or
number at biologically important time
PO 00000
Frm 00021
Fmt 4703
Sfmt 4703
9177
or location) to to helicopter operations
or human presence that we expect to
result in the take of marine mammals
(this goal may contribute to a, above, or
to reducing the severity of harassment
takes only).
5. Avoidance or minimization of
adverse effects to marine mammal
habitat, paying special attention to the
food base, activities that block or limit
passage to or from biologically
important areas, permanent destruction
of habitat, or temporary destruction/
disturbance of habitat during a
biologically important time.
6. For monitoring directly related to
mitigation—an increase in the
probability of detecting marine
mammals, thus allowing for more
effective implementation of the
mitigation.
Based on the evaluation of the
Society’s proposed measures, as well as
other measures considered by us, NMFS
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, and areas of similar
significance.
Summary of Previous Monitoring
The Society complied with the
mitigation and monitoring required
under the previous authorizations
(2010–2013). They did not conduct any
operations for the 2013 season.
However, in compliance with the 2012
Authorization, the Society submitted a
final report on the activities at the
Station, covering the period of February
15, 2012 through April 30, 2012. During
the effective dates of the 2012 IHA, the
Society conducted one work session in
March, 2012. The Society’s aircraft
operations and restoration activities on
NWSR did not exceed the activity levels
analyzed under the 2012 authorization.
During the March 2012 work session,
the Society observed two harbor seals
hauled out on Northwest Seal Rock.
Both animals (a juvenile and an adult)
departed the rock, entered the water,
and did not return to the Station during
the duration of the activities.
Proposed Monitoring
In order to issue an ITA for an
activity, section 101(a)(5)(D) of the
MMPA states that NMFS must set forth
‘‘requirements pertaining to the
monitoring and reporting of such
taking’’. The MMPA implementing
regulations at 50 CFR 216.104 (a)(13)
indicate that requests for Authorizations
must include the suggested means of
accomplishing the necessary monitoring
E:\FR\FM\18FEN1.SGM
18FEN1
tkelley on DSK3SPTVN1PROD with NOTICES
9178
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
and reporting that will result in
increased knowledge of the species and
of the level of taking or impacts on
populations of marine mammals that we
expect to be present in the proposed
action area.
Monitoring measures prescribed by us
should accomplish one or more of the
following general goals:
1. An increase in the probability of
detecting marine mammals, both within
the mitigation zone (thus allowing for
more effective implementation of the
mitigation) and during other times and
locations, in order to generate more data
to contribute to the analyses mentioned
later;
2. An increase in our understanding
of how many marine mammals would
be affected by helicopter operations and
human presence and the likelihood of
associating those exposures with
specific adverse effects, such as
behavioral harassment, temporary or
permanent threshold shift;
3. An increase in our understanding
of how marine mammals respond to
stimuli that we expect to result in take
and how those anticipated adverse
effects on individuals (in different ways
and to varying degrees) may impact the
population, species, or stock
(specifically through effects on annual
rates of recruitment or survival) through
any of the following methods:
a. Behavioral observations in the
presence of stimuli compared to
observations in the absence of stimuli
(i.e., we need to be able to accurately
predict received level, distance from
source, and other pertinent
information);
b. Physiological measurements in the
presence of stimuli compared to
observations in the absence of stimuli
(i.e., we need to be able to accurately
predict received level, distance from
source, and other pertinent
information);
c. Distribution and/or abundance
comparisons in times or areas with
concentrated stimuli versus times or
areas without stimuli;
4. An increased knowledge of the
affected species; and
5. An increase in our understanding
of the effectiveness of certain mitigation
and monitoring measures.
Proposed Monitoring Measures: At
least once during the period between
April 1 through April 30, 2014 and
November 1, 2014 through March 31,
2015, a qualified biologist shall be
present during all three workdays at the
Station. The qualified biologist hired
will be subject to approval by us and
they shall document use of the island by
the pinnipeds, frequency, (i.e., dates,
time, tidal height, species, numbers
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
present, and any disturbances), and note
any responses to potential disturbances.
Aerial photographic surveys may
provide the most accurate means of
documenting species composition, age
and sex class of pinnipeds using the
project site during human activity
periods. The Society should complete
aerial photo coverage of the island from
the same helicopter used to transport
the Society’s personnel to the island
during restoration trips. The Society
would take photographs of all marine
mammals hauled out on the island at an
altitude greater than 300 m (984 ft) by
a skilled photographer, prior to the first
landing on each visit included in the
monitoring program. Photographic
documentation of marine mammals
present at the end of each three-day
work session shall also be made for a
before and after comparison. These
photographs will be forwarded to a
biologist capable of discerning marine
mammal species. Data shall be provided
to us in the form of a report with a data
table, any other significant observations
related to marine mammals, and a report
of restoration activities (see Reporting).
The original photographs can be made
available to us or other marine mammal
experts for inspection and further
analysis.
Proposed Reporting
The Society will submit a draft
Monitoring Report to us no later than 90
days after they complete the project to
the NMFS Director of Office of Protected
Resources. Within 30 days after
receiving comments from us on the draft
Final Monitoring Report, the Society
must submit a Final Monitoring Report
to the NMFS Director of Office of
Protected Resources. If the Society
receives no comments from us on the
draft Monitoring Report, then NMFS
will consider the draft Monitoring
Report to be the Final Monitoring
Report.
The final report will provide:
(i) A summary and table of the dates,
times, and weather during all helicopter
operations, and restoration and
maintenance activities.
(ii) Species, number, location, and
behavior of any marine mammals,
observed throughout all monitoring
activities.
(iii) An estimate of the number (by
species) of marine mammals that are
known to have been exposed to acoustic
stimuli associated with the helicopter
operations, restoration and maintenance
activities.
(iv) A description of the
implementation and effectiveness of the
monitoring and mitigation measures of
the IHA and full documentation of
PO 00000

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 (if
issued), such as an injury (Level A
harassment), serious injury, or mortality
(e.g., vessel-strike, stampede, etc.), the
Society shall immediately cease the
specified activities and immediately
report the incident to the Incidental
Take Program Supervisor, Permits and
Conservation Division, Office of
Protected Resources, NMFS, at 301–
427–8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@
noaa.gov and the Assistant Western
Regional Stranding Coordinator at (562)
980–3264 (Justin.Greenman@noaa.gov).
The report must include the following
information:
• Time, date, and location (latitude/
longitude) of the incident;
• Description and location of the
incident (including water depth, if
applicable);
• Environmental conditions (e.g.,
wind speed and direction, Beaufort sea
state, cloud cover, and visibility);
• Description of all marine mammal
observations in the 24 hours preceding
the incident;
• Species identification or
description of the animal(s) involved;
• Fate of the animal(s); and
• Photographs or video footage of the
animal(s) (if equipment is available).
The Society shall not resume its
activities until NMFS is able to review
the circumstances of the prohibited
take. NMFS shall work with the Society
to determine what is necessary to
minimize the likelihood of further
prohibited take and ensure Marine
Mammal Protection Act compliance.
The Society may not resume their
activities until notified by us via letter,
email, or telephone.
In the event that the Society discovers
an injured or dead marine mammal, and
the lead visual observer 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), the Society will
immediately report the incident to the
Incidental Take Program Supervisor,
Permits and Conservation Division,
Office of Protected Resources, at 301–
427–8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@
noaa.gov and the Assistant Western
Regional Stranding Coordinator at (562)
980–3264 (Justin.Greenman@noaa.gov).
The report must include the same
information identified in the paragraph
above this section. Activities may
E:\FR\FM\18FEN1.SGM
18FEN1
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
continue while NMFS reviews the
circumstances of the incident. NMFS
will work with the Society to determine
whether modifications in the activities
are appropriate.
In the event that the Society 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), the Society will report the
incident to the Incidental Take Program
Supervisor, Permits and Conservation
Division, Office of Protected Resources,
at 301–427–8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@
noaa.gov and the Assistant Western
Regional Stranding Coordinator at (562)
980–3264 (Justin.Greenman@noaa.gov),
within 24 hours of the discovery. The
Society’s staff will provide photographs
or video footage (if available) or other
documentation of the stranded animal
sighting to us.
Estimated Take by Incidental
Harassment
Except with respect to certain
activities not pertinent here, the MMPA
defines ‘‘harassment’’ as:
tkelley on DSK3SPTVN1PROD with NOTICES
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].
NMFS anticipates that the helicopter
operations and restoration and
maintenance activities have the
potential to harass (Level B only) marine
mammals that may be present on
NWSR. Thus NMFS will only authorize
take by Level B harassment as a result
of the helicopter operations and
restoration and maintenance activities
on NWSR.
Based on pinniped survey counts
conducted by CCR on NWSR in the
spring of 1997, 1998, 1999, and 2000
(CCR, 2001), NMFS estimates that
approximately 204 California sea lions
(calculated by multiplying the average
monthly abundance of California sea
lions (zero in April, 1997 and 34 in
April, 1998) present on NWSR by 6
months of the restoration and
maintenance activities), 172 Steller sea
lions (NMFS’ estimate of the maximum
number of Steller sea lions that could be
present on NWSR with a 95-percent
confidence interval), 36 Pacific harbor
seals (calculated by multiplying the
VerDate Mar<15>2010
20:58 Feb 14, 2014
Jkt 232001
maximum number of harbor seals
present on NWSR (6) by 6 months), and
6 northern fur seals (calculated by
multiplying the maximum number of
northern fur seals present on NWSR (1)
by 6 months) could be potentially
affected by Level B behavioral
harassment over the course of the
Authorization. NMFS bases these
estimates of the numbers of marine
mammals that might be affected on
consideration of the number of marine
mammals that could be disturbed
appreciably by approximately 51 hours
of aircraft operations during the course
of the activity. These incidental
harassment take numbers represent
approximately 0.14 percent of the U.S.
stock of California sea lion, 0.42 percent
of the eastern U.S. stock of Steller sea
lion, 0.11 percent of the California stock
of Pacific harbor seals, and 0.06 percent
of the San Miguel Island stock of
northern fur seal. Because of the
required mitigation measures and the
likelihood that some pinnipeds will
avoid the area, NMFS does not expect
any injury or mortality to pinnipeds to
occur and NMFS has not authorized
take by Level A harassment for this
proposed activity.
Encouraging and Coordinating Research
The Society will continue to
coordinate monitoring of pinnipeds
during the helicopter operations and
restoration activities which contribute
to the basic knowledge of marine
mammal biology on NWSR.
Analysis and Preliminary
Determinations
Negligible Impact
Negligible impact is ‘‘an impact
resulting from the specified activity that
cannot be reasonably expected to, and is
not reasonably likely to, adversely affect
the species or stock through effects on
annual rates of recruitment or survival’’
(50 CFR 216.103). The lack of likely
adverse effects on annual rates of
recruitment or survival (i.e., population
level effects) forms the basis of a
negligible impact finding. Thus, an
estimate of the number of Level B
harassment takes, alone, is not enough
information on which to base an impact
determination. In addition to
considering estimates of the number of
marine mammals that might be ‘‘taken’’
through behavioral harassment, NMFS
must consider other factors, such as the
likely nature of any responses (their
intensity, duration, etc.), the context of
any responses (critical reproductive
time or location, migration, etc.), as well
as the number and nature of estimated
Level A harassment takes, and the
PO 00000
Frm 00023
Fmt 4703
Sfmt 4703
9179
number of estimated mortalities, and
effects on habitat.
In making a negligible impact
determination, NMFS considers:
• The number of anticipated injuries,
serious injuries, or mortalities;
• The number, nature, and intensity,
and duration of Level B harassment; and
• The context in which the takes
occur (e.g., impacts to areas of
significance, impacts to local
populations, and cumulative impacts
when taking into account successive/
contemporaneous actions when added
to baseline data);
• The status of stock or species of
marine mammals (i.e., depleted, not
depleted, decreasing, increasing, stable,
impact relative to the size of the
population);
• Impacts on habitat affecting rates of
recruitment/survival; and
• The effectiveness of monitoring and
mitigation measures.
For reasons stated previously in this
document and based on the following
factors, the Society’s specified activities
are not likely to cause long-term
behavioral disturbance, abandonment of
the haulout area, injury, serious injury,
or mortality because:
(1) The effects of the Society’s
operations would be limited to no
responses, short-term startle responses,
or temporary behavioral changes due to
the short and sporadic duration of the
restoration activities. Minor and brief
responses, such as short-duration startle
or alert reactions, are not likely to
constitute disruption of behavioral
patterns, such as migration, nursing,
breeding, feeding, or sheltering.
(2) The availability of alternate areas
for pinnipeds to avoid the resultant
acoustic and visual disturbances from
the restoration activities and helicopter
operations. Results from previous
monitoring reports also show that the
pinnipeds returned to the various sites
and did not permanently abandon haulout sites after the Society conducted
their activities.
(3) There is no potential for largescale movements leading to injury,
serious injury, or mortality because the
Society must delay ingress onto NWSR
until after the pinnipeds present have
slowly entered the water.
NMFS does not anticipate that any
injuries, serious injuries, or mortalities
would occur as a result of the Society’s
proposed activities, and NMFS does not
propose to authorize injury, serious
injury or mortality. These species may
exhibit behavioral modifications,
including temporarily vacating the area
during the proposed helicopter
operations and restoration activities to
avoid the resultant acoustic and visual
E:\FR\FM\18FEN1.SGM
18FEN1
9180
Federal Register / Vol. 79, No. 32 / Tuesday, February 18, 2014 / Notices
disturbances. Further, these proposed
activities would not take place in areas
of significance for marine mammal
feeding, resting, breeding, or calving
and would not adversely impact marine
mammal habitat. Due to the nature,
degree, and context of the behavioral
harassment anticipated, the activities
are not expected to impact rates of
recruitment or survival.
Based on this notice’s analysis 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
Society’s proposed helicopter
operations and restoration/maintenance
activities would have a negligible
impact on the affected marine mammal
species or stocks.
tkelley on DSK3SPTVN1PROD with NOTICES
Small Numbers
As mentioned previously, NMFS
estimates that the Society’s activities
could potentially affect, by Level B
harassment only, four species of marine
mammals under our jurisdiction. For
each species, these estimates are small
numbers (each, less than or equal to one
percent) relative to the population size.
These incidental harassment take
numbers represent approximately 0.14
percent of the U.S. stock of California
sea lion, 0.42 percent of the eastern U.S.
stock of Steller sea lion, 0.11 percent of
the California stock of Pacific harbor
seals, and 0.06 percent of the San
Miguel Island stock of northern fur seal.
Because of the required mitigation
measures and the likelihood that some
pinnipeds will avoid the area, no injury
or mortality to pinnipeds is expected
nor requested. The proposed taking
would be limited to small numbers of
marine mammals, relative to the
population sizes of the affected species
or stocks (i.e., for each species, these
numbers are less than one percent).
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
mitigation and monitoring measures,
NMFS preliminarily finds that the
Society’s proposed helicopter
operations and restoration/maintenance
activities would take small numbers of
marine mammals relative to the
populations of the affected species or
stocks.

Impact on Availability of Affected
Species or Stock for Taking for
Subsistence Uses
There are no relevant subsistence uses
of marine mammals implicated by this
action.
Endangered Species Act (ESA)
NMFS does not expect that the
Society’s proposed helicopter
operations and restoration/maintenance
activities would affect any species listed
under the ESA. Therefore, NMFS has
determined that a section 7 consultation
under the ESA is not required.
National Environmental Policy Act
(NEPA)
To meet our NEPA requirements for
the issuance of an Authorization to the
Society, NMFS has prepared an
Environmental Assessment (EA) in 2010
that was specific to conducting aircraft
operations and restoration and
maintenance work on the St. George
Reef Light Station. The EA, titled
‘‘Issuance of an Incidental Harassment
Authorization to Take Marine Mammals
by Harassment Incidental to Conducting
Aircraft Operations, Lighthouse
Restoration and Maintenance Activities
on St. George Reef Lighthouse Station in
Del Norte County, California,’’ evaluated
the impacts on the human environment
of our authorization of incidental Level
B harassment resulting from the
specified activity in the specified
geographic region. At that time, NMFS
concluded that issuance of an annual
Authorization would not significantly
affect the quality of the human
environment and issued a Finding of No
Significant Impact (FONSI) for the 2010
EA regarding the Society’s activities. In
conjunction with the Society’s 2014
application, NMFS has again reviewed
the 2010 EA and determined that there
are no new direct, indirect or
cumulative impacts to the human and
natural environment associated with the
IHA requiring evaluation in a
supplemental EA and NMFS, therefore,
intends to preliminarily reaffirm the
2010 FONSI. An electronic copy of the
EA and the FONSI for this activity is
available upon request (see ADDRESSES).
Proposed Authorization
As a result of these preliminary
determinations, NMFS proposes issuing
an Authorization to the Society for
conducting helicopter operations and
restoration activities on the St. George
Light Station in the northeast Pacific
Ocean, April 1 through April 30, 2014
and November 1, 2014, through March
31, 2015, provided they incorporate the
previously mentioned mitigation,
monitoring, and reporting requirements.

Draft Authorization
The St. George Reef Lighthouse
Preservation Society (Society), P.O. Box
577, Crescent City, CA 95531, is hereby
authorized under section 101(a)(5)(D) of
the Marine Mammal Protection Act (16
U.S.C. 1371(a)(5)(D)) and 50 CFR
216.107, to harass marine mammals
incidental to conducting helicopter
operations and restoration and
maintenance work on the St. George
Reef Light Station (Station) on
Northwest Seal Rock in the northeast
Pacific Ocean.
1. This Incidental Harassment
Authorization (IHA) is valid from April
1 through April 30, 2014 and November
1, 2014, through March 31, 2015.
2. This IHA is valid only for activities
associated with helicopter operations
and restoration and maintenance
activities (See items 2(a)–(d)) on the
Station on Northwest Seal Rock
(41°50′24″ N, 124°22′06″ W) in the
northeast Pacific Ocean.
a. The use of a small, compact,
4-person helicopter with two-bladed
main and tail rotors fitted with noiseattenuating blade tip caps to transit to
and from Northwest Seal Rock;
b. restoration activities (e.g., painting,
plastering, welding, and glazing)
conducted on the Station;
c. maintenance activities (e.g., bulb
replacement and automation of the light
system) conducted on the Station; and
d. emergency repair events (e.g., the
failure of the PATON beacon light)
between April 1 through April 30, 2014
and November 1, 2014, through March
31, 2015, outside of the three-day work
session.
3. General Conditions
a. A copy of this IHA must be in the
possession of the Society, its designees,
and work crew personnel operating
under the authority of this IHA.
b. The species authorized for taking
are the California sea lion (Zalophus
californianus), Pacific Harbor seal
(Phoca vitulina), the eastern Distinct
Population Segment of Steller sea lion
(Eumetopias jubatus), and the eastern
Pacific stock of northern fur seal
(Callorhinus ursinus).
c. The taking, by Level B harassment
only, is limited to the species listed in
condition 3(b) (See Table 1 for take
numbers, attached).
d. The taking by Level A harassment,
injury or death of any of the species
listed in item 3(b) of the Authorization
or the taking by harassment, injury or
death of any other species of marine

e. In the case of an emergency repair
event (i.e., failure of the PATON beacon
light) between May 1, 2014 through
October 31, 2014, the Society will
consult with the ARA, Western Region,
NMFS, to best determine the timing of
an emergency repair trip to the Station.
a. The Western Region NMFS marine
mammal biologist will make a decision
regarding when the Society can
schedule helicopter trips to the
Northwest Seal Rock during the
emergency repair time window and will
ensure that such operations will have
the least practicable adverse impact to
marine mammals.
b. The ARA, Western Region, NMFS
will also ensure that the Society’s
request for incidental take during an
emergency repair event would not
exceed the number of incidental take
authorized in this IHA.

4. Cooperation
The holder of this Authorization is
required to cooperate with the NMFS
and any other Federal, state, or local
agency authorized to monitor the
impacts of the activity on marine
mammals.
5. Mitigation Measures
In order to ensure the least practicable
impact on the species listed in
condition 3(b), the holder of this
Authorization is required to:
a. Conduct restoration and
maintenance activities at the Station at
a maximum of one session per month
between April 1 through April 30, 2014
and November 1, 2014, through March
31, 2015. Each restoration session will
be no more than three days in duration.
Maintenance of the light beacon will
occur only in conjunction with the
monthly restoration activities.
b. Ensure that helicopter approach
patterns to the Northwest Seal Rock will
be such that the timing techniques are
least disturbing to marine mammals. To
the extent possible, the helicopter
should approach Northwest Seal Rock
when the tide is too high for the marine
mammals to haul-out on Northwest Seal
Rock.
c. Avoid rapid and direct approaches
by the helicopter to the station by
approaching Northwest Seal Rock at a
relatively high altitude (e.g., 800–1,000
ft; 244–305 m). Before the final
approach, the helicopter shall circle
lower, and approach from area where
the density of pinnipeds is the lowest.
If for any safety reasons (e.g., wind
conditions or visibility) such helicopter
approach and timing techniques cannot
be achieved, the Society must abort the
restoration and maintenance session for
that day.

Jkt 232001
d. Provide instructions to the
Society’s members, the restoration crew,
and if applicable, to tourists, on
appropriate conduct when in the
vicinity of hauled-out marine mammals.
The Society’s members, the restoration
crew, and if applicable, tourists, will
avoid making unnecessary noise while
on Northwest Seal Rock and must not
view pinnipeds around the base of the
Station.
e. Ensure that the door to the Station’s
lower platform shall remain closed and
barricaded at all times.
6. Monitoring
The holder of this Authorization is
required to:
a. Have a NMFS-approved biologist
present during all three workdays at the
Station at least once during the period
between April 1 through April 30, 2014
and November 1, 2014, through March
31, 2015. This requirement may be
modified depending on the results of
the monthly monitoring reports. The
biologist shall document use of the
island by the marine mammals (i.e.,
dates, time, tidal height, species,
numbers present, frequency of use,
weather conditions, and any
disturbances), and note any responses to
potential disturbances.
b. Record the date, time, and location
(or closest point of ingress) of each visit
to the Northwest Seal Rock. See Table
2 for an example of a data collection
sheet.
c. Collect the following information
for each visit:
i. Information on the numbers (by
species) of marine mammals observed
during the activities;
ii. the estimated number of marine
mammals (by species) that may have
been harassed during the activities;
iii. any behavioral responses or
modifications of behaviors that may be
attributed to the specific activities (e.g.,
flushing into water, becoming alert and
moving, rafting); and
iv. information on the weather,
including the tidal state and horizontal
visibility.
d. Employ a skilled, aerial
photographer to document marine
mammals hauled out on Northwest Seal
Rock for comparing marine mammal
presence on Northwest Seal Rock preand post-restoration.
i. The photographer will complete a
photographic survey of Northwest Seal
Rock using the same helicopter that will
transport Society personnel to the island
during restoration trips.
ii. For a pre-restoration survey,
photographs of all marine mammals
hauled-out on the island shall be taken
at an altitude greater than 300 m (984 ft)
PO 00000
Frm 00025

during the first arrival flight to
Northwest Seal Rock.
iii. For the post-restoration survey,
photographs of all marine mammals
hauled-out on the island shall be taken
at an altitude greater than 300 m (984 ft)
during the last departure flight from
Northwest Seal Rock;
iv. The Society and/or its designees
will forward the photographs to a
biologist capable of discerning marine
mammal species. The Society shall
provide the data to us in the form of a
report with a data table, any other
significant observations related to
marine mammals, and a report of
restoration activities (see Reporting).
The Society will make available the
original photographs to NMFS or to
other marine mammal experts for
inspection and further analysis.

SUPPLEMENTARY INFORMATION:
Background
Section 101(a)(5)(D) of the Marine Mammal Protection Act of 1972,
as amended (MMPA; 16 U.S.C. 1361 et seq.) directs the Secretary of
Commerce to allow, upon request, the incidental, but not intentional,
taking of small numbers of marine mammals of a species or population
stock, by United States citizens who engage in a specified activity
(other than commercial fishing) within a specified geographical region
if, after notice of a proposed authorization to the public for review
and public comment: (1) We make certain findings; and (2) the taking is
limited to harassment.
An authorization shall be granted for the incidental taking of
small numbers of marine mammals if NMFS finds that the taking will have
a negligible impact on the species or stock(s), and will not have an
unmitigable adverse impact on the availability of the species or
stock(s) for subsistence uses (where relevant). The authorization must
also set forth the permissible methods of taking; other means of
effecting the least practicable adverse impact on the species or stock
and its habitat; and requirements pertaining to the mitigation,
monitoring and reporting of such taking. NMFS has defined ``negligible
impact'' in 50 CFR 216.103 as ``an impact resulting from the specified
activity that cannot be reasonably expected to, and is not reasonably
likely to, adversely affect the species or stock through effects on
annual rates of recruitment or survival.''
Except with respect to certain activities not pertinent here, the
MMPA defines ``harassment'' as: Any act of pursuit, torment, or
annoyance which (i) has the potential to injure a marine mammal or
marine mammal stock in the wild [Level A harassment]; or (ii) has the
potential to disturb a marine mammal or marine mammal stock in the wild
by causing disruption of behavioral patterns, including, but not
limited to, migration, breathing, nursing, breeding, feeding, or
sheltering [Level B harassment].
Summary of Request
On December 14, 2013, NMFS received an application from the Society
requesting that we issue an Authorization for the take of marine
mammals, incidental to conducting restoration activities on the St.
George Reef Light Station (Station) located on Northwest Seal Rock
offshore of Crescent City, California in the northeast Pacific Ocean.
NMS determined the application complete and adequate on January 13,
2014.
The Society proposes to conduct aircraft operations, lighthouse
renovation, and periodic maintenance on the Station's optical light
system on a monthly basis. The proposed activity would occur on a
monthly basis over one weekend, April 1 through April 30, 2014 and
November 1, 2014, through
[[Page 9171]]
February 28, 2015. The following specific aspects of the proposed
activities have the potential to take marine mammals: (1) Helicopter
landings/takeoffs; (2) noise generated during restoration activities
(e.g., painting, plastering, welding, and glazing); (3) maintenance
activities (e.g., bulb replacement and automation of the light system);
and (4) human presence. Thus, we anticipate that take, by Level B
harassment only, of California sea lions (Zalophus californianus);
Pacific harbor seals (Phoca vitulina); Steller sea lions (Eumetopias
jubatus) of the eastern U.S. Stock; and northern fur seals (Callorhinus
ursinus) could result from the specified activity.
To date, we have issued four, Authorizations to the Society for the
conduct of the same activities from 2010 to 2013 (75 FR 4774, January
29, 2010; 76 FR 10564, February 25, 2011; 77 FR 8811, February 15,
2012; and 79 FR 6179, February 3, 2014). This is the Society's fifth
request for an annual Authorization as their last Authorization expired
on December 31, 2013.
Description of the Specified Activity
Overview
The Station, listed in the National Park Service's National
Register of Historic Places, is located on Northwest Seal Rock offshore
of Crescent City, California in the northeast Pacific Ocean. The
Station, built in 1892, rises 45.7 meters (m) (150 feet (ft)) above sea
level. The structure consists of hundreds of granite blocks topped with
a cast iron lantern room and covers much of the surface of the islet.
The purpose of the project is to restore the lighthouse and to conduct
annual and emergency maintenance on the Station's optical light system.
Dates and Duration
The Society proposes to conduct the activities (aircraft
operations, lighthouse restoration, and maintenance activities) from
the period of April 1, 2014 through March 31, 2015, at a maximum
frequency of one session per month. The proposed duration for each
session would last no more than three days (e.g., Friday, Saturday, and
Sunday). The proposed Authorization, if issued, would be effective from
April 1, 2014 through April 30, 2014 and November 1, 2014, through
March 31, 2015.
We refer the reader to the Detailed Description of Activities
section later in this notice for more information on the scope of the
proposed activities.
Specified Geographic Region
The Station is located on a small, rocky islet (41[deg]50'24'' N,
124[deg]22'06'' W) approximately nine kilometers (km) (6.0 miles (mi))
in the northeast Pacific Ocean, offshore of Crescent City, California
(Latitude: 41[deg]46'48'' N; Longitude: 124[deg]14'11'' W). NWSR is
approximately 91.4 m (300 ft) in diameter that peaks at 5.18 m (17 ft)
above mean sea level.
Detailed Description of Activities
Aircraft Operations
Because Northwest Seal Rock has no safe landing area for boats, the
proposed restoration activities would require the Society to transport
personnel and equipment from the California mainland to Northwest Seal
Rock by a small helicopter. Helicopter landings take place on top of
the engine room (caisson) which is approximately 15 m (48 ft) above the
surface of the rocks on Northwest Seal Rock. The Society plans to
charter a Raven R44 helicopter, owned and operated by Air Shasta Rotor
and Wing, LLC. The Raven R44, which seats three passengers and one
pilot, is a compact-sized (1134 kilograms (kg), 2500 pounds (lbs))
helicopter with two-bladed main and tail rotors. Both sets of rotors
are fitted with noise-attenuating blade tip caps that would decrease
flyover noise.
The Society proposes to transport no more than 15 work crew members
and equipment to Northwest Seal Rock for each session and estimates
that each session would require no more than 36 helicopter landings/
takeoffs per month. During landing, the helicopter would land on the
caisson to allow the work crew members to disembark and retrieve their
equipment located in a basket attached to the underside of the
helicopter. The helicopter would then return to the mainland to pick up
additional personnel and equipment.
Proposed schedule: The Society would conduct a maximum of 16
flights (eight arrivals and eight departures) for the first day. The
first flight would depart from Crescent City Airport at approximately 9
a.m. for a 6-minute flight to Northwest Seal Rock. The helicopter would
land and takeoff immediately after offloading personnel and equipment
every 20 minutes (min). The total duration of the first day's aerial
operations could last for approximately 3 hours (hrs) and 26 min and
would end at approximately 12:34 p.m. Crew members would remain
overnight at the Station and would not return to the mainland on the
first day.
For the second day, the Society would conduct a maximum of 10
flights (five arrivals and five departures) to transport additional
materials on and off the islet. The first flight would depart from
Crescent City Airport at 9 a.m. for a 6-minute flight to Northwest Seal
Rock. The total duration of the second day's aerial operations could
last up to three hours.
For the final day of operations, the Society could conduct a
maximum of eight helicopter flights (four arrivals and four departures)
to transport the remaining crew members and equipment/material back to
the Crescent City Airport. The total duration of the third day's
helicopter operations in support of restoration could last up to 2 hrs
and 14 min.
Lighthouse Restoration Activities
Restoration and maintenance activities would involve the removal of
peeling paint and plaster, restoration of interior plaster and paint,
refurbishing structural and decorative metal, reworking original metal
support beams throughout the lantern room and elsewhere, replacing
glass as necessary, upgrading the present electrical system; and annual
light beacon maintenance.
Light Maintenance Activities
The Society will need to conduct maintenance on the Station's
beacon light at least once or up to two times per year within the
proposed work window. Scheduled light maintenance activities would
coincide with lighthouse restoration activities conducted monthly
during the period of April 1 through April 30, 2014 and during the
period of November 1, 2014, through March 31, 2015. The Society expects
that maintenance activities would not exceed 3 hrs per each monthly
session.
Emergency Light Maintenance
If the beacon light fails during the period from April 1 through
April 30, 2014 or November 1, 2014 through March 31, 2015, the Society
proposes to send a crew of two to three people to the Station by
helicopter to repair the beacon light. For each emergency repair event,
the Society proposes to conduct a maximum of four flights (two arrivals
and two departures) to transport equipment and supplies. The helicopter
may remain on site or transit back to shore and make a second landing
to pick up the repair personnel.
In the case of an emergency repair between May 1, 2014, and October
31, 2014, the Society would consult with the NMFS' Western Regional
Office (WRO) biologists to best determine the timing of the trips to
the lighthouse, on a case-by-case basis, based upon the existing
environmental conditions and
[[Page 9172]]
the abundance and distribution of any marine mammals present on NWSR.
The regional biologists would have real-time knowledge regarding the
animal use and abundance of the NWSR at the time of the repair request
and would make a decision regarding when the Society could conduct
trips to the lighthouse during the emergency repair time window that
would have the least practicable adverse impact to marine mammals. The
WRO biologists would also ensure that the Society's request for
incidental take during emergency repairs would not exceed the number of
incidental take authorized in the proposed Authorization. To date, the
Society has not needed to conduct emergency light maintenance between
May through October under any of the four previous Authorizations.
Sound Sources and Sound Characteristics
NMFS expects that acoustic stimuli resulting from the proposed
helicopter operations; noise from maintenance and restoration
activities; and human presence have the potential to harass marine
mammals, incidental to the conduct of the proposed activities.
This section includes a brief explanation of the sound measurements
frequently used in the discussions of acoustic effects in this notice.
Sound pressure is the sound force per unit area, and is usually
measured in micropascals ([mu]Pa), where 1 pascal (Pa) is the pressure
resulting from a force of one newton exerted over an area of one square
meter. Sound pressure level (SPL) is the ratio of a measured sound
pressure and a reference level. The commonly used reference pressure is
1 [mu]Pa for under water, and the units for SPLs are dB re: 1 [mu]Pa.
The commonly used reference pressure is 20 [mu]Pa for in air, and the
units for SPLs are dB re: 20 [mu]Pa.
SPL (in decibels (dB)) = 20 log (pressure/reference pressure).
SPL is an instantaneous measurement expressed as the peak, the
peak-peak (p-p), or the root mean square (rms). Root mean square is the
square root of the arithmetic average of the squared instantaneous
pressure values. All references to SPL in this document refer to the
root mean square unless otherwise noted. SPL does not take into account
the duration of a sound.
R44 Helicopter Sound Characteristics
Noise testing performed on the R44 Raven Helicopter, as required
for Federal Aviation Administration approval, required an overflight at
150 m (492 ft) above ground level, 109 knots and a maximum gross weight
of 1,134 kg (2,500 lbs). The noise levels measured on the ground at
this distance and speed were 81.9 decibels (dB) re: 20 [mu]Pa (A-
weighted) for the model R44 Raven I, or 81.0 dB re: 20 [mu]Pa (A-
weighted) for the model R44 Raven II (NMFS, 2007).
Based on this information, we expect that the received sound levels
at the landing area on the Station's caisson would increase above 81-
81.9 dB re: 20 [mu]Pa (A-weighted).
Restoration and Maintenance Sound Characteristics
Any noise associated with these activities is likely to be from
light construction (e.g., sanding, hammering, or use of hand drills).
The Society proposes to confine all restoration activities to the
existing structure which would occur on the upper levels of the
Station. Pinnipeds hauled out on Northwest Seal Rock do not have access
to the upper levels of the Station.
Description of Marine Mammals in the Area of the Specified Activity
Table 1 provides the following: All marine mammal species with
possible or confirmed occurrence in the proposed activity area;
information on those species' regulatory status under the MMPA and the

There are several cetaceans that have the potential to transit in
the vicinity of the lighthouse station including the short-beaked
common (Delphinus delphis) and the Pacific white-sided (Lagenorhynchus
obliquidens) dolphin; the blue (Balaenoptera musculus), fin
(Balaenoptera physalus), gray (Eschrichtius robustus), humpback
(Megaptera novaeangliae), killer (Orcinus orca), North Pacific right
(Eubalaena japonica), sei (Balaenoptera borealis), and sperm (Physeter
macrocephalus) whales; and the Guadalupe fur seal (Arctocephalus
townsendi). We will not consider these species further in this notice
of a proposed Incidental Harassment Authorization because these are
unlikely or rare in the nearshore environment of NWSR and the Society's
operations would not likely affect these species--as the bulk of the
their activities occur on the Station's caisson.
California (southern) sea otters (Enhydra lutris nereis), listed as
threatened under the ESA and categorized as depleted under the MMPA,
usually range in coastal waters within two km (1.2 mi) of the mainland
shore. Neither CCR nor the Society has encountered California sea
otters on Northwest Seal Rock during the course of the four-year
wildlife study (CCR, 2001) nor has the Society encountered the species
during the course of the previous three Authorizations. The U.S. Fish
and Wildlife Service (USFWS) manages the sea otter and we will not
consider this species further in this notice of a proposed
Authorization.
[[Page 9173]]
The marine mammals most likely to be harassed incidental to the
Society's helicopter operations, lighthouse restoration, and lighthouse
maintenance on Northwest Seal Rock are primarily Steller and California
sea lions and to a lesser extent the Pacific harbor seal and the
eastern Pacific stock of northern fur seal. We refer the public to
Carretta et al., (2013) and Allen and Angliss (2013) for general
information on these species which we present in this notice. The
publications are available at https://www.nmfs.noaa.gov/pr/sars/region.htm. We present a summary of information on these species below
this section.
California Sea Lion
The California sea lion is now a full species, separated from the
Galapagos sea lion (Z. wollebaeki) and the extinct Japanese sea lion
(Z. japonicus) (Brunner 2003, Wolf et al., 2007, Schramm et al., 2009).
The estimated population of the U.S. stock of California sea lion is
approximately 296,750 animals and the current maximum population growth
rate is 12 percent (Carretta et al., 2013).
California sea lion breeding areas are on islands located in
southern California, in western Baja California, Mexico, and the Gulf
of California. During the breeding season, most California sea lions
inhabit southern California and Mexico. Rookery sites in southern
California are limited to the San Miguel Islands and the southerly
Channel Islands of San Nicolas, Santa Barbara, and San Clemente
(Carretta et al., 2013). Males establish breeding territories during
May through July on both land and in the water. Females come ashore in
mid-May and June where they give birth to a single pup approximately
four to five days after arrival and will nurse pups for about a week
before going on their first feeding trip. Females will alternate
feeding trips with nursing bouts until weaning between four and 10
months of age (NMML, 2010).
Adult and juvenile males will migrate as far north as British
Columbia, Canada while females and pups remain in southern California
waters in the non-breeding season. In warm water (El Ni[ntilde]o)
years, some females range as far north as Washington and Oregon,
presumably following prey.
Crescent Coastal Research (CCR) conducted a three-year (1998-2000)
survey of the wildlife species on NWSR for the Society. They reported
that counts of California sea lions on NWSR varied greatly (from six to
541) during the observation period from April 1997 through July 2000.
CCR reported that counts for California sea lions during the spring
(April--May), summer (June-August), and fall (September-October),
averaged 60, 154, and 235, respectively (CCR, 2001).
The most current counts for the month of July by NMFS (2000 through
2004) have been relatively low as the total number of California sea
lions recorded in 2000 and 2003 was 3 and 11, respectively (M. Lowry,
NMFS, SWFSC, unpublished data). Based on the monitoring report for the
2011 season, the maximum numbers of California sea lions present during
the April and November, 2011 work sessions was 2 and 90 animals,
respectively (SGRLPS, 2012). There were no California sea lions present
during the March, 2012 work session (SGRLPS, 2012).
Northern Fur Seal
Northern fur seals occur from southern California north to the
Bering Sea and west to the Sea of Okhotsk and Honshu Island of Japan.
NMFS recognizes two separate stocks of northern fur seals within U.S.
waters: An Eastern Pacific stock distributed among sites in Alaska,
British Columbia; and a San Miguel Island stock distributed along the
west coast of the continental U.S. The estimated population of the San
Miguel Island stock is 9,968 animals with a maximum population growth
rate of 12 percent (Carretta et al., 2013).
Northern fur seals may temporarily haul out on land at other sites
in Alaska, British Columbia, and on islets along the west coast of the
continental United States, but generally this occurs outside of the
breeding season (Fiscus, 1983).
Northern fur seals breed in Alaska and migrate along the west coast
during fall and winter. Due to their pelagic habitat, they are rarely
seen from shore in the continental U.S., but individuals occasionally
come ashore on islands well offshore (i.e., Farallon Islands and
Channel Islands in California). During the breeding season,
approximately 74 percent of the worldwide population inhabits the
Pribilof Islands in Alaska, with the remaining animals spread
throughout the North Pacific Ocean (Lander and Kajimura, 1982).
CCR observed one male northern fur seal on Northwest Seal Rock in
October, 1998 (CCR, 2001). It is possible that a few animals may use
the island more often that indicated by the CCR surveys, if they were
mistaken for other otariid species (i.e., eared seals or fur seals and
sea lions) (M. DeAngelis, NMFS, pers. comm.).
For the 2010, 2011, and 2012 work seasons, the Society has not
observed any northern fur seals present on Northwest Seal Rock during
restoration activities (SGRLPS, 2010; 2011; 2012). The Society did not
conduct any operations for the 2013 season.
Pacific Harbor Seal
The estimated population of the California stock of Pacific harbor
seals is approximately 30,196 animals (Carretta et al., 2013). There is
no current estimate of abundance available for the Oregon/Washington
stock (Carretta et al., 2013).
The animals inhabit near-shore coastal and estuarine areas from
Baja California, Mexico, to the Pribilof Islands in Alaska. Pacific
harbor seals consist of two subspecies: P. v. stejnegeri in the western
North Pacific, near Japan, and P. v. richardsi in the northeast Pacific
Ocean. The latter subspecies, recognized as three separate stocks,
inhabits the west coast of the continental United States, including:
The outer coastal waters of Oregon and Washington states; Washington
state inland waters; and Alaska coastal and inland waters. Two of these
stocks, the California stock and Oregon/Washington coast stock, of
Pacific harbor seals are identified off the coast of Oregon and
California for management purposes under the MMPA. However, the stock
boundary is difficult to distinguish because of the continuous
distribution of harbor seals along the west coast and any rigid
boundary line is (to a greater or lesser extent) arbitrary, from a
biological perspective (Carretta et al., 2011). Due to the location of
the proposed project which is situated near the border of Oregon and
California, both stocks could be present within the proposed project
area.
In California, over 500 harbor seal haulout sites are widely
distributed along the mainland and offshore islands, and include rocky
shores, beaches and intertidal sandbars (Lowry et al., 2005). Harbor
seals mate at sea and females give birth during the spring and summer,
although, the pupping season varies with latitude. Females nurse their
pups for an average of 24 days and are ready to swim minutes after
being born. Harbor seal pupping takes place at many locations and
rookery size varies from a few pups to many hundreds of pups. The
nearest harbor seal rookery relative to the proposed project site is at
Castle Rock National Wildlife Refuge, located approximately located 965
m (0.6 mi) south of Point St. George, and 2.4 km (1.5 mi) north of the
Crescent City Harbor in Del Norte County, California (USFWS, 2007).
[[Page 9174]]
CCR noted that harbor seal use of Northwest Seal Rock was minimal,
with only one sighting of a group of six animals, during 20 observation
surveys. They hypothesized that harbor seals may avoid the islet
because of its distance from shore, relatively steep topography, and
full exposure to rough and frequently turbulent sea swells. For the
2010 and 2011 seasons, the Society did not observe any Pacific harbor
seals present on Northwest Seal Rock during restoration activities
(SGRLPS, 2010; 2011). During the 2012 season, the Society reported
sighting a total of two harbor seals present on Northwest Seal Rock
(SGRLPS, 2012). The Society did not conduct any operations for the 2013
season.
Steller Sea Lion
Steller sea lions consist of two distinct population segments: the
western and eastern distinct population segments (DPS) divided at
144[deg] West longitude (Cape Suckling, Alaska). The western segment of
Steller sea lions inhabit central and western Gulf of Alaska, Aleutian
Islands, as well as coastal waters and breed in Asia (e.g., Japan and
Russia). The eastern segment includes sea lions living in southeast
Alaska, British Columbia, California, and Oregon.
Steller sea lions range along the North Pacific Rim from northern
Japan to California (Loughlin et al., 1984), with centers of abundance
and distribution in the Gulf of Alaska and Aleutian Islands,
respectively. The species is not known to migrate, but individuals
disperse widely outside of the breeding season (late May through early
July), thus potentially intermixing with animals from other areas.
In 2012, the estimated population of the eastern distinct
population segment ranged from a minimum of 58,334 up to 72,223 animals
and the maximum population growth rate is 12 percent (Allen and
Angliss, 2013). On October 23, 2013 NMFS announced the removal of the
eastern distinct population segment of Steller sea lions from the list
of threatened species under the ESA. As of December 4, 2013 the eastern
DPS is not a threatened species listed under the ESA. With the
delisting, federal agencies proposing actions that may affect the
eastern Steller sea lions are no longer required to consult with NMFS
under section 7 of the ESA.
The eastern distinct population segment of Steller sea lions breeds
on rookeries located in southeast Alaska, British Columbia, Oregon, and
California. There are no rookeries located in Washington state. Steller
sea lions give birth in May through July and breeding commences a
couple of weeks after birth. Pups are weaned during the winter and
spring of the following year.
Despite the wide-ranging movements of juveniles and adult males in
particular, exchange between rookeries by breeding adult females and
males (other than between adjoining rookeries) appears low, although
males have a higher tendency to disperse than females (NMFS, 1995;
Trujillo et al., 2004; Hoffman et al., 2006). A northward shift in the
overall breeding distribution has occurred, with a contraction of the
range in southern California and new rookeries established in
southeastern Alaska (Pitcher et al., 2007). Overall, counts of non-pups
at trend sites in California and Oregon have been relatively stable or
increasing slowly since the 1980s (Allen and Angliss, 2012).
CCR reported that Steller sea lion numbers at Northwest Seal Rock
ranged from 20 to 355 animals. Counts of Steller sea lions during the
spring (April--May), summer (June-August), and fall (September-
October), averaged 68, 110, and 56, respectively (CCR, 2001). A more
recent survey at NWSR between 2000 and 2004 showed Steller sea lion
numbers ranged from 175 to 354 in July (M. Lowry, NMFS/SWFSC, unpubl.
data). The Society presumes that winter use of NWSR by Steller sea lion
to be minimal, due to inundation of the natural portion of the island
by large swells.
For the 2010 season, the Society reported that no Steller sea lions
were present in the vicinity of Northwest Seal Rock during restoration
activities (SGRLPS, 2010). Based on the monitoring report for the 2011
season, the maximum numbers of Steller sea lions present during the
April and November 2011, work sessions was 2 and 150 animals,
respectively (SGRLPS, 2012). During the 2012 season, the Society did
not observe any Steller sea lions present on Northwest Seal Rock during
restoration activities. The Society did not conduct any operations for
the 2013 season.
Potential Effects of the Specified Activities on Marine Mammals
This section includes a summary and discussion of the ways that the
types of stressors associated with the specified activity (e.g.,
aircraft operations and human presence) have the potential to impact
marine mammals. This discussion may also include reactions that we
consider to rise to the level of a take and those that we do not
consider to rise to the level of a take (e.g., with acoustics, we may
include a discussion of studies that show animals not reacting to sound
or animals exhibiting barely perceptible avoidance behaviors). We also
intend this section to provide a background of potential effects of the
Society's activities. This section does not consider the specific
manner in which the Society would carry out the proposed activity, what
mitigation measures the Society would implement, and how either of
those would shape the anticipated impacts from this specific activity.
The ``Estimated Take by Incidental Harassment'' section later in this
document will include a quantitative analysis of the number of
individuals that we expect the Society to take during this activity.
The ``Negligible Impact Analysis'' section will include the analysis of
how this specific activity would impact marine mammals. We will
consider the content of the following sections: (1) Negligible Impact
Analysis; (2) Estimated Take by Incidental Harassment; (3) Proposed
Mitigation; and (4) Anticipated Effects on Marine Mammal Habitat, to
draw conclusions regarding the likely impacts of the Society's
activities on the reproductive success or survivorship of individuals--
and from that consideration--the likely impacts of this activity on the
affected marine mammal populations or stocks.
Acoustic Impacts
Acoustic and visual stimuli generated by: (1) Helicopter landings/
takeoffs; (2) noise generated during restoration activities (e.g.,
painting, plastering, welding, and glazing); and (3) maintenance
activities (e.g., bulb replacement and automation of the light system)
may have the potential to cause the following: temporary or permanent
hearing impairment and/or behavioral disturbance (Southall, et al.,
2007).
When considering the influence of various kinds of sound on the
marine environment, it is necessary to understand that different kinds
of marine life are sensitive to different frequencies of sound and
current data indicate that not all marine mammal species have equal
hearing capabilities (Richardson et al., 1995; Wartzok and Ketten,
1999). Southall et al. (2007) designated ``functional hearing groups''
for marine mammals based on available behavioral data; audiograms
derived from auditory evoked potentials; anatomical modeling; and other
data. Southall et al. (2007) also estimated the lower and upper
frequencies of functional hearing for each group as animals are less
sensitive to sounds at the lower and upper frequency limits of their
functional hearing range and are more sensitive to a range of
frequencies
[[Page 9175]]
within the middle of their functional hearing range.
The functional groups and the associated frequencies are:
Low frequency cetaceans (13 species of mysticetes):
functional hearing estimates occur between approximately 7 Hertz (Hz)
and 30 kHz (extended from 22 kHz based on data indicating that some
mysticetes can hear above 22 kHz; Au et al., 2006; Lucifredi and Stein,
2007; Ketten and Mountain, 2009; Tubelli et al., 2012);
Mid-frequency cetaceans (32 species of dolphins, six
species of larger toothed whales, and 19 species of beaked and
bottlenose whales): functional hearing estimates occur between
approximately 150 Hz and 160 kHz;
High-frequency cetaceans (eight species of true porpoises,
six species of river dolphins, Kogia, the franciscana, and four species
of cephalorhynchids): functional hearing estimates occur between
approximately 200 Hz and 180 kHz; and
Pinnipeds in water: functional hearing estimates occur
between approximately 75 Hz and 100 kHz, with the greatest sensitivity
between approximately 700 Hz and 20 kHz.
As mentioned previously in this document, four marine mammal
species would likely occur in the proposed action area. All are
pinnipeds and fall under the Pinnipeds in water functional hearing
group category. We consider a species' functional hearing group when we
analyze the effects of exposure to sound on marine mammals.
Helicopter Noise
Marine mammals produce sounds in various important contexts--social
interactions, foraging, navigating, and to responding to predators. The
best available science suggests that pinnipeds have a functional aerial
hearing sensitivity between 75 hertz (Hz) and 75 kilohertz (kHz) and
can produce a diversity of sounds, though generally from 100 Hz to
several tens of kHz (Southall, et al., 2007).
Exposure to high intensity sound for a sufficient duration may
result in auditory effects such as a noise-induced threshold shift--an
increase in the auditory threshold after exposure to noise (Finneran,
Carder, Schlundt, and Ridgway, 2005). Factors that influence the amount
of threshold shift include the amplitude, duration, frequency content,
temporal pattern, and energy distribution of noise exposure. The
magnitude of hearing threshold shift normally decreases over time
following cessation of the noise exposure. The amount of threshold
shift just after exposure is called the initial threshold shift. If the
threshold shift eventually returns to zero (i.e., the threshold returns
to the pre-exposure value), it is called temporary threshold shift
(TTS) (Southall et al., 2007).
Pinnipeds have the potential to be disturbed by airborne and
underwater noise generated by the engine of the aircraft (Born, Riget,
Dietz, & Andriashek, 1999; Richardson, Greene, Malme, & Thomson, 1995).
Data on underwater TTS-onset in pinnipeds exposed to pulses are limited
to a single study which exposed two California sea lions to single
underwater pulses from an arc-gap transducer and found no measurable
TTS following exposures up to 183 dB re: 1 [mu]Pa (peak-to-peak)
(Finneran, Dear, Carder, & Ridgway, 2003).
Researchers have demonstrated TTS in certain captive odontocetes
and pinnipeds exposed to strong sounds (reviewed in Southall et al.,
2007). In 2004, researchers measured auditory fatigue to airborne sound
in harbor seals, California sea lions, and northern elephant seals
after exposure to non-pulse noise for 25 minutes (Kastak, Southall,
Holt, Kastak, & Schusterman, 2004). In the study, the harbor seal
experienced approximately 6 dB of TTS at 99 dB re: 20 [mu]Pa. The
authors identified onset of TTS in the California sea lion at 122 dB
re: 20 [mu]Pa. The northern elephant seal experienced TTS-onset at 121
dB re: 20 [mu]Pa (Kastak, et al., 2004).
There is a dearth of information on acoustic effects of helicopter
overflights on pinniped hearing and communication (Richardson, et al.,
1995) and to NMFS' knowledge, there has been no specific documentation
of TTS, let alone permanent threshold shift (PTS), in free-ranging
pinnipeds exposed to helicopter operations during realistic field
conditions (Baker, Jensz, & Chilvers, 2012; Scheidat et al., 2011).
In 2008, we issued an Authorization to the USFWS for the take of
small numbers of Steller sea lions and Pacific harbor seals, incidental
to rodent eradication activities on an islet offshore of Rat Island, AK
conducted by helicopter. The 15-minute aerial treatment consisted of
the helicopter slowly approaching the islet at an elevation of over
1,000 feet (304.8 m); gradually decreasing altitude in slow circles;
and applying the rodenticide in a single pass and returning to Rat
Island. The gradual and deliberate approach to the islet resulted in
the sea lions present initially becoming aware of the helicopter and
calmly moving into the water. Further, the USFWS reported that all
responses fell well within the range of Level B harassment (i.e., alert
head raises without moving or limited, short-term displacement
resulting from aircraft noise due to helicopter overflights).
As a general statement from the available information, pinnipeds
exposed to intense (approximately 110 to 120 dB re: 20 [mu]Pa) non-
pulse sounds often leave haulout areas and seek refuge temporarily
(minutes to a few hours) in the water (Southall et al., 2007). Any
noise attributed to the Society's proposed helicopter operations on
NWSR would be short-term (approximately 5 min per trip). We would
expect the ambient noise levels to return to a baseline state when
helicopter operations have ceased for the day. Per Richardson et al.
(1995), approaching aircraft generally flush animals into the water and
noise from a helicopter is typically directed down in a ``cone''
underneath the aircraft. As the helicopter landings take place 15 m (48
ft) above the surface of the rocks on NWSR, we presume that the
received sound levels would increase above 81-81.9 dB re: 20 [mu]Pa (A-
weighted) at the landing pad. However, we do not expect that the
increased received levels of sound from the helicopter would cause TTS
or PTS because the pinnipeds would flush before the helicopter
approached NWSR; thus increasing the distance between the pinnipeds and
the received sound levels on NWSR during the proposed action.
Visual Disturbance
There is increasing recognition that the effect of human
disturbance wildlife is highly dependent on the nature of the
disturbance (Burger et al., 1995; Klein et al., 1995; and Kucey, 2005).
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; Mortenson et al., 2000; and Kucey and
Trites, 2006). The apparent skittishness of both harbor seals and
Steller sea lions raises concerns regarding behavioral and
physiological impacts to individuals and populations experiencing high
levels of human disturbance. Human activity can flush harbor seals off
haul out sites (Allen et al., 1984; Calambokidis et al., 1991; Suryan
and Harvey, 1999; Mortenson et al., 2000).
The Hawaiian monk seal (Monachus schauinslandi) may avoid beaches
disturbed by humans (Kenyon, 1972). Stevens and Boness (2003) concluded
that after the 1997-98 El Ni[ntilde]o, when populations of the South
American fur
[[Page 9176]]
seal, Arctocephalus australis, in Peru declined dramatically, seals
abandoned some of their former primary breeding sites, but continued to
breed at adjacent beaches that were more rugged (i.e., less likely to
be used by humans). Abandoned and unused sites were more likely to have
human disturbance than currently used sites. In one case, human
disturbance appeared to cause Steller sea lions to desert a breeding
area at Northeast Point on St. Paul Island, Alaska (Kenyon, 1962).
It is likely that the initial helicopter approach to the Station
would cause a subset, or all of the marine mammals hauled out on NWSR
to depart the rock and flush into the water. The physical presence of
aircraft could also lead to non-auditory effects on marine mammals
involving visual or other cues. Airborne sound from a low-flying
helicopter or airplane may be heard by marine mammals while at the
surface or underwater. In general, helicopters tend to be noisier than
fixed wing aircraft of similar size and underwater sounds from aircraft
are strongest just below the surface and directly under the aircraft.
Noise from aircraft would not be expected to cause direct physical
effects but have the potential to affect behavior. The primary factor
that may influence abrupt movements of animals is engine noise,
specifically changes in engine noise. Responses by mammals could
include hasty dives or turns, change in course, or flushing and
stampeding from a haul out site. There are few well documented studies
of the impacts of aircraft overflight over pinniped haul out sites or
rookeries, and many of those that exist, are specific to military
activities (Efroymson et al., 2001).
Several factors complicate the analysis of long- and short-term
effects for aircraft overflights. Information on behavioral effects of
overflights by military aircraft (or component stressors) on most
wildlife species is sparse. Moreover, models that relate behavioral
changes to abundance or reproduction, and those that relate behavioral
or hearing effects thresholds from one population to another are
generally not available. In addition, the aggregation of sound
frequencies, durations, and the view of the aircraft into a single
exposure metric is not always the best predictor of effects and it may
also be difficult to calculate. Overall, there has been no indication
that single or occasional aircraft flying above pinnipeds in water
cause long term displacement of these animals (Richardson et al.,
1995). The Lowest Observed Adverse Effects Levels (LOAELs) are rather
variable for pinnipeds on land, ranging from just over 150 m (492 ft)
to about 2,000 m (6,562 ft) (Efroymson et al., 2001). A conservative
(90th percentile) distance effects level is 1,150 m (3,773 ft). Most
thresholds represent movement away from the overflight. Bowles and
Stewart (1980) estimated an LOAEL of 305 m (1,000 ft) for helicopters
(low and landing) in California sea lions and harbor seals observed on
San Miguel Island, CA; animals responded to some degree by moving
within the haul out and entering into the water, stampeding into the
water, or clearing the haul out completely. Both species always
responded with the raising of their heads. California sea lions
appeared to react more to the visual cue of the helicopter than the
noise.
If pinnipeds are present on NWSR, it is likely that a helicopter
landing at the Station would cause some number of the pinnipeds on NWSR
to flush; however, when present, they appear to show rapid habituation
to helicopter landing and departure (Crescent Coastal Research, 2001;
Guy Towers, SGRLPS, pers. com.). According to the CCR Report (2001),
while up to 40 percent of the California and Steller sea lions present
on the rock have been observed to enter the water on the first of a
series of helicopter landings, as few as zero percent have flushed on
subsequent landings on the same date. In fact, the Society reported
that during the November 2011 work session, Steller sea lions and
California sea lions exhibited minimal ingress and egress from
Northwest Seal Rock during helicopter approaches and departures
(SGRLPS, 2011).
If pinnipeds are present on NWSR, Level B behavioral harassment of
pinnipeds may occur during helicopter landing and takeoff from NWSR due
to the pinnipeds temporarily moving from the rocks and lower structure
of the Station into the sea due to the noise and appearance of
helicopter during approaches and departures. It is expected that all or
a portion of the marine mammals hauled out on the island will depart
the rock and move into the water upon initial helicopter approaches.
The movement to the water would be gradual due to the required
controlled helicopter approaches (see Proposed Mitigation section), the
small size of the aircraft, the use of noise-attenuating blade tip caps
on the rotors, and behavioral habituation on the part of the animals as
helicopter trips continue throughout the day. During the sessions of
helicopter activity, if present on NWSR, some animals may be
temporarily displaced from the island and either raft in the water or
relocate to other haul-outs.
Sea lions have shown habituation to helicopter flights within a day
at the project site and most animals are expected to return soon after
helicopter activities cease for that day. By clustering helicopter
arrival/departures within a short time period, we expect animals
present to show less response to subsequent landings. We anticipate no
impact on the population size or breeding stock of Steller sea lions,
California sea lions, Pacific harbor seals, or northern fur seals.
Restoration and maintenance activities would involve the removal of
peeling paint and plaster, restoration of interior plaster and paint,
refurbishing structural and decorative metal, reworking original metal
support beams throughout the lantern room and elsewhere, replacing
glass as necessary, upgrading the present electrical system; and annual
light beacon maintenance. Any noise associated with these activities is
likely to be from light construction (e.g., sanding, hammering, or use
of hand drills) and the pinnipeds may be disturbed by human presence.
Animals respond to disturbance from humans in the same way as they
respond to the risk of predation, by avoiding areas of high risk,
either completely or by using them for limited periods (Gill et al.,
1996).
Stampede
Sudden movement of large numbers of animals may cause a stampede.
In order to prevent such stampedes from occurring within the sea lion
colony, we would require certain mitigation requirements and
restrictions, such as controlled helicopter approaches and limited
access period during the pupping season, should we issue an
Authorization. As such, and because any pinnipeds nearby likely would
avoid the approaching helicopter, the Society anticipates that there
will be no instances of injury or mortality during the proposed
project.
Anticipated Effects on Marine Mammal Habitat
NMFS does not expect that the proposed activity would have any
effects on marine mammal habitat. Based on previous monitoring reports
and anecdotal observations, up to 315 animals could use the small,
rocky base at the base of the Station as a haulout site. The Society
proposes to confine all restoration activities to the existing
structure which would occur on the upper levels of the Station which
are not used by marine mammals. Thus, NMFS expects that there will be
no long- or short-term physical impacts to pinniped habitat on NWSR.
[[Page 9177]]
The Society would remove all waste, discarded materials and
equipment from the island after each visit. The proposed activities
will not result in any permanent impact on habitats used by marine
mammals, including prey species and foraging habitat. The main impact
associated with the proposed activity will be temporarily elevated
noise levels and the associated direct effects on marine mammals (i.e.,
the potential for temporary abandonment of the site), previously
discussed in this notice.
Proposed Mitigation
In order to issue an incidental take authorization under section
101(a)(5)(D) of the MMPA, NMFS must set forth the permissible methods
of taking pursuant to such activity, and other means of effecting the
least practicable adverse impact on such species or stock and its
habitat, paying particular attention to rookeries, mating grounds, and
areas of similar significance, and on the availability of such species
or stock for taking for certain subsistence uses (where relevant).
As a way to reduce or minimize adverse impacts that would result
from the proposed project to the lowest level practicable, NMFS
proposes to require the following mitigation measures.
Time and Frequency: The Society would conduct restoration
activities at maximum of once per month between April 1 through April
30, 2014 and November 1, 2014, through March 31, 2015. Each restoration
session would last no more than three days. Maintenance of the light
beacon would occur only in conjunction with restoration activities.
Helicopter Approach and Timing Techniques: The Society would ensure
that its helicopter approach patterns to the Station and timing
techniques do not disturb marine mammals as most practicable. To the
extent possible, the helicopter should approach NWSR when the tide is
too high for the marine mammals to haul-out on NWSR.
Since the most severe impacts (stampede) precede rapid and direct
helicopter approaches, the Society's initial approach to the Station
must be offshore from the island at a relatively high altitude (e.g.,
800-1,000 ft, or 244-305 m). Before the final approach, the helicopter
shall circle lower, and approach from area with the lowest pinniped
density. If for any safety reasons (e.g., wind condition) the Society
cannot conduct these types of helicopter approach and timing
techniques, they must abort the restoration and maintenance activities
for that day.
Avoidance of Visual and Acoustic Contact with People on Island: The
Society would instruct its members and restoration crews to avoid
making unnecessary noise and not expose themselves visually to
pinnipeds around the base of the Station. Although CCR reported no
impacts from these activities in the 2001 CCR study, it is relatively
simple for the Society to avoid this potential impact. The door to the
lower platform (which is used at times by pinnipeds) shall remain
closed and barricaded to all tourists and other personnel.
Mitigation Conclusions
NMFS has carefully evaluated the Society's proposed mitigation
measures in the context of ensuring that we prescribe the means of
effecting the least practicable impact on the affected marine mammal
species and stocks and their habitat. Our evaluation of potential
measures included consideration of the following factors in relation to
one another:
The manner in which, and the degree to which, the
successful implementation of the measure is expected to minimize
adverse impacts to marine mammals;
The proven or likely efficacy of the specific measure to
minimize adverse impacts as planned; and
The practicability of the measure for applicant
implementation.
Any mitigation measure(s) prescribed by us should be able to
accomplish, have a reasonable likelihood of accomplishing (based on
current science), or contribute to the accomplishment of one or more of
the general goals listed here:
1. Avoidance or minimization of injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may contribute to this goal).
2. A reduction in the numbers of marine mammals (total number or
number at biologically important time or location) exposed to
helicopter operations and human presence that we expect to result in
the take of marine mammals (this goal may contribute to 1, above, or to
reducing harassment takes only).
3. A reduction in the number of times (total number or number at
biologically important time or location) individuals would be exposed
to helicopter operations or human presence that we expect to result in
the take of marine mammals (this goal may contribute to 1, above, or to
reducing harassment takes only).
4. A reduction in the intensity of exposures (either total number
or number at biologically important time or location) to to helicopter
operations or human presence that we expect to result in the take of
marine mammals (this goal may contribute to a, above, or to reducing
the severity of harassment takes only).
5. Avoidance or minimization of adverse effects to marine mammal
habitat, paying special attention to the food base, activities that
block or limit passage to or from biologically important areas,
permanent destruction of habitat, or temporary destruction/disturbance
of habitat during a biologically important time.
6. For monitoring directly related to mitigation--an increase in
the probability of detecting marine mammals, thus allowing for more
effective implementation of the mitigation.
Based on the evaluation of the Society's proposed measures, as well
as other measures considered by us, NMFS 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, and
areas of similar significance.
Summary of Previous Monitoring
The Society complied with the mitigation and monitoring required
under the previous authorizations (2010-2013). They did not conduct any
operations for the 2013 season. However, in compliance with the 2012
Authorization, the Society submitted a final report on the activities
at the Station, covering the period of February 15, 2012 through April
30, 2012. During the effective dates of the 2012 IHA, the Society
conducted one work session in March, 2012. The Society's aircraft
operations and restoration activities on NWSR did not exceed the
activity levels analyzed under the 2012 authorization. During the March
2012 work session, the Society observed two harbor seals hauled out on
Northwest Seal Rock. Both animals (a juvenile and an adult) departed
the rock, entered the water, and did not return to the Station during
the duration of the activities.
Proposed Monitoring
In order to issue an ITA for an activity, section 101(a)(5)(D) of
the MMPA states that NMFS must set forth ``requirements pertaining to
the monitoring and reporting of such taking''. The MMPA implementing
regulations at 50 CFR 216.104 (a)(13) indicate that requests for
Authorizations must include the suggested means of accomplishing the
necessary monitoring
[[Page 9178]]
and reporting that will result in increased knowledge of the species
and of the level of taking or impacts on populations of marine mammals
that we expect to be present in the proposed action area.
Monitoring measures prescribed by us should accomplish one or more
of the following general goals:
1. An increase in the probability of detecting marine mammals, both
within the mitigation zone (thus allowing for more effective
implementation of the mitigation) and during other times and locations,
in order to generate more data to contribute to the analyses mentioned
later;
2. An increase in our understanding of how many marine mammals
would be affected by helicopter operations and human presence and the
likelihood of associating those exposures with specific adverse
effects, such as behavioral harassment, temporary or permanent
threshold shift;
3. An increase in our understanding of how marine mammals respond
to stimuli that we expect to result in take and how those anticipated
adverse effects on individuals (in different ways and to varying
degrees) may impact the population, species, or stock (specifically
through effects on annual rates of recruitment or survival) through any
of the following methods:
a. Behavioral observations in the presence of stimuli compared to
observations in the absence of stimuli (i.e., we need to be able to
accurately predict received level, distance from source, and other
pertinent information);
b. Physiological measurements in the presence of stimuli compared
to observations in the absence of stimuli (i.e., we need to be able to
accurately predict received level, distance from source, and other
pertinent information);
c. Distribution and/or abundance comparisons in times or areas with
concentrated stimuli versus times or areas without stimuli;
4. An increased knowledge of the affected species; and
5. An increase in our understanding of the effectiveness of certain
mitigation and monitoring measures.
Proposed Monitoring Measures: At least once during the period
between April 1 through April 30, 2014 and November 1, 2014 through
March 31, 2015, a qualified biologist shall be present during all three
workdays at the Station. The qualified biologist hired will be subject
to approval by us and they shall document use of the island by the
pinnipeds, frequency, (i.e., dates, time, tidal height, species,
numbers present, and any disturbances), and note any responses to
potential disturbances.
Aerial photographic surveys may provide the most accurate means of
documenting species composition, age and sex class of pinnipeds using
the project site during human activity periods. The Society should
complete aerial photo coverage of the island from the same helicopter
used to transport the Society's personnel to the island during
restoration trips. The Society would take photographs of all marine
mammals hauled out on the island at an altitude greater than 300 m (984
ft) by a skilled photographer, prior to the first landing on each visit
included in the monitoring program. Photographic documentation of
marine mammals present at the end of each three-day work session shall
also be made for a before and after comparison. These photographs will
be forwarded to a biologist capable of discerning marine mammal
species. Data shall be provided to us in the form of a report with a
data table, any other significant observations related to marine
mammals, and a report of restoration activities (see Reporting). The
original photographs can be made available to us or other marine mammal
experts for inspection and further analysis.
Proposed Reporting
The Society will submit a draft Monitoring Report to us no later
than 90 days after they complete the project to the NMFS Director of
Office of Protected Resources. Within 30 days after receiving comments
from us on the draft Final Monitoring Report, the Society must submit a
Final Monitoring Report to the NMFS Director of Office of Protected
Resources. If the Society receives no comments from us on the draft
Monitoring Report, then NMFS will consider the draft Monitoring Report
to be the Final Monitoring Report.
The final report will provide:
(i) A summary and table of the dates, times, and weather during all
helicopter operations, and restoration and maintenance activities.
(ii) Species, number, location, and behavior of any marine mammals,
observed throughout all monitoring activities.
(iii) An estimate of the number (by species) of marine mammals that
are known to have been exposed to acoustic stimuli associated with the
helicopter operations, restoration and maintenance activities.
(iv) A description of the implementation and effectiveness of the
monitoring and mitigation measures of the IHA 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 (if issued), such as an injury (Level A harassment),
serious injury, or mortality (e.g., vessel-strike, stampede, etc.), the
Society shall immediately cease the specified activities and
immediately report the incident to the Incidental Take Program
Supervisor, Permits and Conservation Division, Office of Protected
Resources, NMFS, at 301-427-8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@noaa.gov and the Assistant Western
Regional Stranding Coordinator at (562) 980-3264
(Justin.Greenman@noaa.gov). The report must include the following
information:
Time, date, and location (latitude/longitude) of the
incident;
Description and location of the incident (including water
depth, if applicable);
Environmental conditions (e.g., wind speed and direction,
Beaufort sea state, cloud cover, and visibility);
Description of all marine mammal observations in the 24
hours preceding the incident;
Species identification or description of the animal(s)
involved;
Fate of the animal(s); and
Photographs or video footage of the animal(s) (if
equipment is available).
The Society shall not resume its activities until NMFS is able to
review the circumstances of the prohibited take. NMFS shall work with
the Society to determine what is necessary to minimize the likelihood
of further prohibited take and ensure Marine Mammal Protection Act
compliance. The Society may not resume their activities until notified
by us via letter, email, or telephone.
In the event that the Society discovers an injured or dead marine
mammal, and the lead visual observer 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), the Society will immediately report the incident to the
Incidental Take Program Supervisor, Permits and Conservation Division,
Office of Protected Resources, at 301-427-8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@noaa.gov and the Assistant Western
Regional Stranding Coordinator at (562) 980-3264
(Justin.Greenman@noaa.gov). The report must include the same
information identified in the paragraph above this section. Activities
may
[[Page 9179]]
continue while NMFS reviews the circumstances of the incident. NMFS
will work with the Society to determine whether modifications in the
activities are appropriate.
In the event that the Society 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), the Society will report the
incident to the Incidental Take Program Supervisor, Permits and
Conservation Division, Office of Protected Resources, at 301-427-8401
and/or by email to Jolie.Harrison@noaa.gov and ITP.Cody@noaa.gov and
the Assistant Western Regional Stranding Coordinator at (562) 980-3264
(Justin.Greenman@noaa.gov), within 24 hours of the discovery. The
Society's staff will provide photographs or video footage (if
available) or other documentation of the stranded animal sighting to
us.
Estimated Take by Incidental Harassment
Except with respect to certain activities not pertinent here, the
MMPA defines ``harassment'' as:
any act of pursuit, torment, or annoyance which (i) has the
potential to injure a marine mammal or marine mammal stock in the
wild [Level A harassment]; or (ii) has the potential to disturb a
marine mammal or marine mammal stock in the wild by causing
disruption of behavioral patterns, including, but not limited to,
migration, breathing, nursing, breeding, feeding, or sheltering
[Level B harassment].
NMFS anticipates that the helicopter operations and restoration and
maintenance activities have the potential to harass (Level B only)
marine mammals that may be present on NWSR. Thus NMFS will only
authorize take by Level B harassment as a result of the helicopter
operations and restoration and maintenance activities on NWSR.
Based on pinniped survey counts conducted by CCR on NWSR in the
spring of 1997, 1998, 1999, and 2000 (CCR, 2001), NMFS estimates that
approximately 204 California sea lions (calculated by multiplying the
average monthly abundance of California sea lions (zero in April, 1997
and 34 in April, 1998) present on NWSR by 6 months of the restoration
and maintenance activities), 172 Steller sea lions (NMFS' estimate of
the maximum number of Steller sea lions that could be present on NWSR
with a 95-percent confidence interval), 36 Pacific harbor seals
(calculated by multiplying the maximum number of harbor seals present
on NWSR (6) by 6 months), and 6 northern fur seals (calculated by
multiplying the maximum number of northern fur seals present on NWSR
(1) by 6 months) could be potentially affected by Level B behavioral
harassment over the course of the Authorization. NMFS bases these
estimates of the numbers of marine mammals that might be affected on
consideration of the number of marine mammals that could be disturbed
appreciably by approximately 51 hours of aircraft operations during the
course of the activity. These incidental harassment take numbers
represent approximately 0.14 percent of the U.S. stock of California
sea lion, 0.42 percent of the eastern U.S. stock of Steller sea lion,
0.11 percent of the California stock of Pacific harbor seals, and 0.06
percent of the San Miguel Island stock of northern fur seal. Because of
the required mitigation measures and the likelihood that some pinnipeds
will avoid the area, NMFS does not expect any injury or mortality to
pinnipeds to occur and NMFS has not authorized take by Level A
harassment for this proposed activity.
Encouraging and Coordinating Research
The Society will continue to coordinate monitoring of pinnipeds
during the helicopter operations and restoration activities which
contribute to the basic knowledge of marine mammal biology on NWSR.
Analysis and Preliminary Determinations
Negligible Impact
Negligible impact is ``an impact resulting from the specified
activity that cannot be reasonably expected to, and is not reasonably
likely to, adversely affect the species or stock through effects on
annual rates of recruitment or survival'' (50 CFR 216.103). The lack of
likely adverse effects on annual rates of recruitment or survival
(i.e., population level effects) forms the basis of a negligible impact
finding. Thus, an estimate of the number of Level B harassment takes,
alone, is not enough information on which to base an impact
determination. In addition to considering estimates of the number of
marine mammals that might be ``taken'' through behavioral harassment,
NMFS must consider other factors, such as the likely nature of any
responses (their intensity, duration, etc.), the context of any
responses (critical reproductive time or location, migration, etc.), as
well as the number and nature of estimated Level A harassment takes,
and the number of estimated mortalities, and effects on habitat.
In making a negligible impact determination, NMFS considers:
The number of anticipated injuries, serious injuries, or
mortalities;
The number, nature, and intensity, and duration of Level B
harassment; and
The context in which the takes occur (e.g., impacts to
areas of significance, impacts to local populations, and cumulative
impacts when taking into account successive/contemporaneous actions
when added to baseline data);
The status of stock or species of marine mammals (i.e.,
depleted, not depleted, decreasing, increasing, stable, impact relative
to the size of the population);
Impacts on habitat affecting rates of recruitment/
survival; and
The effectiveness of monitoring and mitigation measures.
For reasons stated previously in this document and based on the
following factors, the Society's specified activities are not likely to
cause long-term behavioral disturbance, abandonment of the haulout
area, injury, serious injury, or mortality because:
(1) The effects of the Society's operations would be limited to no
responses, short-term startle responses, or temporary behavioral
changes due to the short and sporadic duration of the restoration
activities. Minor and brief responses, such as short-duration startle
or alert reactions, are not likely to constitute disruption of
behavioral patterns, such as migration, nursing, breeding, feeding, or
sheltering.
(2) The availability of alternate areas for pinnipeds to avoid the
resultant acoustic and visual disturbances from the restoration
activities and helicopter operations. Results from previous monitoring
reports also show that the pinnipeds returned to the various sites and
did not permanently abandon haul-out sites after the Society conducted
their activities.
(3) There is no potential for large-scale movements leading to
injury, serious injury, or mortality because the Society must delay
ingress onto NWSR until after the pinnipeds present have slowly entered
the water.
NMFS does not anticipate that any injuries, serious injuries, or
mortalities would occur as a result of the Society's proposed
activities, and NMFS does not propose to authorize injury, serious
injury or mortality. These species may exhibit behavioral
modifications, including temporarily vacating the area during the
proposed helicopter operations and restoration activities to avoid the
resultant acoustic and visual
[[Page 9180]]
disturbances. Further, these proposed activities would not take place
in areas of significance for marine mammal feeding, resting, breeding,
or calving and would not adversely impact marine mammal habitat. Due to
the nature, degree, and context of the behavioral harassment
anticipated, the activities are not expected to impact rates of
recruitment or survival.
Based on this notice's analysis 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 Society's
proposed helicopter operations and restoration/maintenance activities
would have a negligible impact on the affected marine mammal species or
stocks.
Small Numbers
As mentioned previously, NMFS estimates that the Society's
activities could potentially affect, by Level B harassment only, four
species of marine mammals under our jurisdiction. For each species,
these estimates are small numbers (each, less than or equal to one
percent) relative to the population size. These incidental harassment
take numbers represent approximately 0.14 percent of the U.S. stock of
California sea lion, 0.42 percent of the eastern U.S. stock of Steller
sea lion, 0.11 percent of the California stock of Pacific harbor seals,
and 0.06 percent of the San Miguel Island stock of northern fur seal.
Because of the required mitigation measures and the likelihood that
some pinnipeds will avoid the area, no injury or mortality to pinnipeds
is expected nor requested. The proposed taking would be limited to
small numbers of marine mammals, relative to the population sizes of
the affected species or stocks (i.e., for each species, these numbers
are less than one percent).
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 mitigation and monitoring
measures, NMFS preliminarily finds that the Society's proposed
helicopter operations and restoration/maintenance activities would take
small numbers of marine mammals relative to the populations of the
affected species or stocks.
Impact on Availability of Affected Species or Stock for Taking for
Subsistence Uses
There are no relevant subsistence uses of marine mammals implicated
by this action.
Endangered Species Act (ESA)
NMFS does not expect that the Society's proposed helicopter
operations and restoration/maintenance activities would affect any
species listed under the ESA. Therefore, NMFS has determined that a
section 7 consultation under the ESA is not required.
National Environmental Policy Act (NEPA)
To meet our NEPA requirements for the issuance of an Authorization
to the Society, NMFS has prepared an Environmental Assessment (EA) in
2010 that was specific to conducting aircraft operations and
restoration and maintenance work on the St. George Reef Light Station.
The EA, titled ``Issuance of an Incidental Harassment Authorization to
Take Marine Mammals by Harassment Incidental to Conducting Aircraft
Operations, Lighthouse Restoration and Maintenance Activities on St.
George Reef Lighthouse Station in Del Norte County, California,''
evaluated the impacts on the human environment of our authorization of
incidental Level B harassment resulting from the specified activity in
the specified geographic region. At that time, NMFS concluded that
issuance of an annual Authorization would not significantly affect the
quality of the human environment and issued a Finding of No Significant
Impact (FONSI) for the 2010 EA regarding the Society's activities. In
conjunction with the Society's 2014 application, NMFS has again
reviewed the 2010 EA and determined that there are no new direct,
indirect or cumulative impacts to the human and natural environment
associated with the IHA requiring evaluation in a supplemental EA and
NMFS, therefore, intends to preliminarily reaffirm the 2010 FONSI. An
electronic copy of the EA and the FONSI for this activity is available
upon request (see ADDRESSES).
Proposed Authorization
As a result of these preliminary determinations, NMFS proposes
issuing an Authorization to the Society for conducting helicopter
operations and restoration activities on the St. George Light Station
in the northeast Pacific Ocean, April 1 through April 30, 2014 and
November 1, 2014, through March 31, 2015, provided they incorporate the
previously mentioned mitigation, monitoring, and reporting
requirements.
Draft Authorization
The St. George Reef Lighthouse Preservation Society (Society), P.O.
Box 577, Crescent City, CA 95531, is hereby authorized under section
101(a)(5)(D) of the Marine Mammal Protection Act (16 U.S.C.
1371(a)(5)(D)) and 50 CFR 216.107, to harass marine mammals incidental
to conducting helicopter operations and restoration and maintenance
work on the St. George Reef Light Station (Station) on Northwest Seal
Rock in the northeast Pacific Ocean.
1. This Incidental Harassment Authorization (IHA) is valid from
April 1 through April 30, 2014 and November 1, 2014, through March 31,
2015.
2. This IHA is valid only for activities associated with helicopter
operations and restoration and maintenance activities (See items 2(a)-
(d)) on the Station on Northwest Seal Rock (41[deg]50'24'' N,
124[deg]22'06'' W) in the northeast Pacific Ocean.
a. The use of a small, compact, 4-person helicopter with two-bladed
main and tail rotors fitted with noise-attenuating blade tip caps to
transit to and from Northwest Seal Rock;
b. restoration activities (e.g., painting, plastering, welding, and
glazing) conducted on the Station;
c. maintenance activities (e.g., bulb replacement and automation of
the light system) conducted on the Station; and
d. emergency repair events (e.g., the failure of the PATON beacon
light) between April 1 through April 30, 2014 and November 1, 2014,
through March 31, 2015, outside of the three-day work session.
3. General Conditions
a. A copy of this IHA must be in the possession of the Society, its
designees, and work crew personnel operating under the authority of
this IHA.
b. The species authorized for taking are the California sea lion
(Zalophus californianus), Pacific Harbor seal (Phoca vitulina), the
eastern Distinct Population Segment of Steller sea lion (Eumetopias
jubatus), and the eastern Pacific stock of northern fur seal
(Callorhinus ursinus).
c. The taking, by Level B harassment only, is limited to the
species listed in condition 3(b) (See Table 1 for take numbers,
attached).
d. The taking by Level A harassment, injury or death of any of the
species listed in item 3(b) of the Authorization or the taking by
harassment, injury or death of any other species of marine mammal is
prohibited and may result in the modification, suspension, or
revocation of this IHA.
[[Page 9181]]
e. In the case of an emergency repair event (i.e., failure of the
PATON beacon light) between May 1, 2014 through October 31, 2014, the
Society will consult with the ARA, Western Region, NMFS, to best
determine the timing of an emergency repair trip to the Station.
a. The Western Region NMFS marine mammal biologist will make a
decision regarding when the Society can schedule helicopter trips to
the Northwest Seal Rock during the emergency repair time window and
will ensure that such operations will have the least practicable
adverse impact to marine mammals.
b. The ARA, Western Region, NMFS will also ensure that the
Society's request for incidental take during an emergency repair event
would not exceed the number of incidental take authorized in this IHA.
4. Cooperation
The holder of this Authorization is required to cooperate with the
NMFS and any other Federal, state, or local agency authorized to
monitor the impacts of the activity on marine mammals.
5. Mitigation Measures
In order to ensure the least practicable impact on the species
listed in condition 3(b), the holder of this Authorization is required
to:
a. Conduct restoration and maintenance activities at the Station at
a maximum of one session per month between April 1 through April 30,
2014 and November 1, 2014, through March 31, 2015. Each restoration
session will be no more than three days in duration. Maintenance of the
light beacon will occur only in conjunction with the monthly
restoration activities.
b. Ensure that helicopter approach patterns to the Northwest Seal
Rock will be such that the timing techniques are least disturbing to
marine mammals. To the extent possible, the helicopter should approach
Northwest Seal Rock when the tide is too high for the marine mammals to
haul-out on Northwest Seal Rock.
c. Avoid rapid and direct approaches by the helicopter to the
station by approaching Northwest Seal Rock at a relatively high
altitude (e.g., 800-1,000 ft; 244-305 m). Before the final approach,
the helicopter shall circle lower, and approach from area where the
density of pinnipeds is the lowest. If for any safety reasons (e.g.,
wind conditions or visibility) such helicopter approach and timing
techniques cannot be achieved, the Society must abort the restoration
and maintenance session for that day.
d. Provide instructions to the Society's members, the restoration
crew, and if applicable, to tourists, on appropriate conduct when in
the vicinity of hauled-out marine mammals. The Society's members, the
restoration crew, and if applicable, tourists, will avoid making
unnecessary noise while on Northwest Seal Rock and must not view
pinnipeds around the base of the Station.
e. Ensure that the door to the Station's lower platform shall
remain closed and barricaded at all times.
6. Monitoring
The holder of this Authorization is required to:
a. Have a NMFS-approved biologist present during all three workdays
at the Station at least once during the period between April 1 through
April 30, 2014 and November 1, 2014, through March 31, 2015. This
requirement may be modified depending on the results of the monthly
monitoring reports. The biologist shall document use of the island by
the marine mammals (i.e., dates, time, tidal height, species, numbers
present, frequency of use, weather conditions, and any disturbances),
and note any responses to potential disturbances.
b. Record the date, time, and location (or closest point of
ingress) of each visit to the Northwest Seal Rock. See Table 2 for an
example of a data collection sheet.
c. Collect the following information for each visit:
i. Information on the numbers (by species) of marine mammals
observed during the activities;
ii. the estimated number of marine mammals (by species) that may
have been harassed during the activities;
iii. any behavioral responses or modifications of behaviors that
may be attributed to the specific activities (e.g., flushing into
water, becoming alert and moving, rafting); and
iv. information on the weather, including the tidal state and
horizontal visibility.
d. Employ a skilled, aerial photographer to document marine mammals
hauled out on Northwest Seal Rock for comparing marine mammal presence
on Northwest Seal Rock pre- and post-restoration.
i. The photographer will complete a photographic survey of
Northwest Seal Rock using the same helicopter that will transport
Society personnel to the island during restoration trips.
ii. For a pre-restoration survey, photographs of all marine mammals
hauled-out on the island shall be taken at an altitude greater than 300
m (984 ft) during the first arrival flight to Northwest Seal Rock.
iii. For the post-restoration survey, photographs of all marine
mammals hauled-out on the island shall be taken at an altitude greater
than 300 m (984 ft) during the last departure flight from Northwest
Seal Rock;
iv. The Society and/or its designees will forward the photographs
to a biologist capable of discerning marine mammal species. The Society
shall provide the data to us in the form of a report with a data table,
any other significant observations related to marine mammals, and a
report of restoration activities (see Reporting). The Society will make
available the original photographs to NMFS or to other marine mammal
experts for inspection and further analysis.
7. Reporting Requirements
Final Report: The holder of this authorization is required to
submit a draft monitoring report to the Chief, Permits and Conservation
Division, Office of Protected Resources, NMFS, 1315 East West Highway,

Society to determine what is necessary to minimize the likelihood of
further prohibited take and ensure Marine Mammal Protection Act
compliance. The Society may not resume their activities until notified
by us via letter, email, or telephone.
9. Reporting an Injured or Dead Marine Mammal With an Unknown Cause of
Death
In the event that the Society discovers an injured or dead marine
mammal, and the lead visual observer 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), the Society will immediately report the incident to the
Incidental Take Program Supervisor, Permits and Conservation Division,
Office of Protected Resources, at 301-427-8401 and/or by email to
Jolie.Harrison@noaa.gov and ITP.Cody@noaa.gov and the Assistant Western

paragraph above. Activities may continue while we review the
circumstances of the incident. We will work with the Society to
determine whether modifications in the activities are appropriate.
10. Reporting an Injured or Dead Marine Mammal Not Related to the
SGRLPS' Activities
In the event that the Society 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), the Society will report the
incident to the Incidental Take Program Supervisor, Permits and
Conservation Division, Office of Protected Resources, at 301-427-8401
