unintentional mortalities of California
sea lions are authorized. The permit
expires September 30, 2017.
The permit holder is requesting the
permit be amended to expand the scope
of the study and include authorization
for capture, sampling, and release of
California sea lions as described above
at two additional sampling sites in
California (160 animals at San Nicolas
Island and 80 animals at Monterey Bay).
A limited number of non-target sea lions
may be captured and released without
sampling. The permit holder also
requests incidental disturbance at each
of the new sites for the following
species: California sea lions (6,000 on
San Nicolas Island; and 3,000 in
Monterey Bay); Northern elephant seals
(2,000 on San Nicolas; and 100 in
Monterey Bay); and Pacific harbor seals
(100 on San Nicolas, and 50 in
Monterey Bay). The permit holder
proposes to disentangle and mark/
sample a limited number of California
sea lions encountered during the
research activities. Permission to
increase the number of mortalities of
California sea lions from four to eight
over the duration of the permit is
requested. The applicant also requests
to extend the maximum number of
sampling years from four to five over the
duration of the permit.
In compliance with the National
Environmental Policy Act of 1969 (42
U.S.C. 4321 et seq.), an initial
determination has been made that the
activity proposed is categorically
excluded from the requirement to
prepare an environmental assessment or
environmental impact statement.
Concurrent with the publication of
this notice in the Federal Register,
NMFS is forwarding copies of this
application to the Marine Mammal
Commission and its Committee of
Scientific Advisors.

amended (MMPA; 16 U.S.C. 1361 et
seq.) directs the Secretary of Commerce
to authorize, 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.
We shall grant authorization for the
incidental taking of small numbers of
marine mammals if we find 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 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. We have
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.’’
Section 101(a)(5)(D) of the MMPA
established an expedited process by
which citizens of the United States can
apply for an authorization to
incidentally take small numbers of
marine mammals by harassment.
Section 101(a)(5)(D) of the MMPA
establishes a 45-day time limit for our
review of an application followed by a
30-day public notice and comment
period on any proposed authorizations
for the incidental harassment of small
numbers of marine mammals. Within 45
days of the close of the public comment
period, we must either issue or deny the
authorization and must publish a notice
in the Federal Register within 30 days
of our determination to issue or deny
the authorization.
The National Defense Authorization
Act of 2004 (NDAA; (Pub. L. 108–136))
amended section 101(a)(5)(A) of the
MMPA by removing the small numbers
and specified geographic region
provisions; revising the definition of
harassment as it applies to a military
readiness activity; and explicitly
requiring that our determination of
‘‘least practicable adverse impact’’
include consideration of: (1) Personnel
safety; (2) the practicality of
implementation; and (3) impact on the

effectiveness of the military readiness
activity.
The NDAA’s definition of harassment
as it applies to a military readiness
activity is: (i) Any act that injures or has
the significant potential to injure a
marine mammal or marine mammal
stock in the wild [Level A Harassment];
or (ii) any act that disturbs or is likely
to disturb a marine mammal or marine
mammal stock in the wild by causing
disruption of natural behavioral
patterns, including, but not limited to,
migration, surfacing, nursing, breeding,
feeding, or sheltering, to a point where
such behavioral patterns are abandoned
or significantly altered [Level B
Harassment].
Summary of Request
We received a request from the
Marine Corps on January 28, 2013,
requesting that we issue an Incidental
Harassment Authorization
(Authorization) for the take, by Level B
harassment only, of small numbers of
Atlantic bottlenose dolphins (Tursiops
truncatus) incidental to air-to-surface
and surface-to-surface training exercises
conducted around two bombing targets
within southern Pamlico Sound, North
Carolina, at Marine Corps Air Station
Cherry Point. We received a complete
and adequate application on March 19,
2013 and released the application for
public comment (see ADDRESSES) for
consideration of issuing an
Authorization to the USMC. To date, we
have issued two, 1-year Authorizations
to the Marine Corps for the conduct of
the same activities from 2010 to 2012
(75 FR 72807, November 26, 2010; 77
FR January 3, 2012).
Description of the Specified Activity
The Marine Corps plan to conduct
weapon delivery training at two
bombing targets: Brant Island Target
(BT–9) and Piney Island Bombing Range
(BT–11) within MCAS Cherry Point
Range Complex, located within Pamlico
Sound, North Carolina. The two targets
are located at the convergence of the
Neuse River and Pamlico Sound.
Training at BT–9 would involve airto-surface (from aircraft to in-water
targets) and surface-to-surface (from
vessels to in-water targets) warfare
training, including bombing, strafing,
special (laser systems) weapons; surface
fires using non-explosive and explosive
ordnance; and mine laying exercises
(inert). Training at BT–11 would involve
air- to-surface exercises to provide
training in the delivery of conventional
(non-explosive) and special (laser
systems) weapons. Surface-to-surface
training by small military watercraft
would also be executed here. The types
of ordnances proposed for use at BT–9
and BT–11 include small arms, large
arms, bombs, rockets, missiles, and
pyrotechnics. All munitions used at BT–
11 are inert, practice rounds and no live
firing would occur at BT–11. Training
for any activity may occur year-round.
The Marine Corps requested
authorization to harass bottlenose
dolphins from firing exercises
conducted at two bombing targets
within MCAS Cherry Point Range
Complex, located within Pamlico
Sound, North Carolina at the
convergence of the Neuse River and
Pamlico Sound. These activities include
gunnery; mine laying; bombing; or
rocket exercises and are classified into
two categories here based on delivery
method: (1) Surface-to-surface gunnery
and (2) air-to-surface bombing. Active
sonar is not a component of these
specified training exercises.
Exercises may occur year round, day
or night (approximately 15 percent of
training occurs at night). The Marine
Corps would conduct all inert and livefire exercises so that all ammunition
and other ordnances strike and/or fall
on the land or water based target or
within the existing danger zones or
water restricted areas.
Acoustic stimuli (i.e., increased
underwater sound) generated during the
training exercises, may have the
potential to cause behavioral
disturbance for marine mammals in BT–
9 and BT–11. This is the principal
means of marine mammal taking
associated with these activities. We
expect these disturbances to be
temporary and result in a temporary
modification in behavior and/or lowlevel physiological effects (Level B
harassment only) of small numbers of
certain species of marine mammals.
We have outlined the purpose of the
program in a previous notice for the
proposed Authorization (78 FR 19224,
Friday, March 29, 2013). Refer to the
notice of the proposed Authorization
(78 FR 19224, Friday, March 29, 2013),
the application, and the Marine Corps’
EA for a more detailed description of
the authorized action.
The amounts of all ordnance to be
expended at BT–9 and BT–11 (both
surface-to-surface and air-to-surface) are
1,225,815 and 1,254,684 rounds,
respectively (see Table 1 and 2).

Comments and Responses
We published a notice of receipt of
the Marine Corps’ application and
proposed Authorization in the Federal
Register on Friday, March 29, 2013 (78
FR 19224). During the 30-day public
comment period, we received comments
from the Marine Mammal Commission
(Commission) and four private citizens.
These comments are online at: https://
www.nmfs.noaa.gov/pr/permits/
incidental.htm. Following are the
comments and our responses.
Comment 1: The Commission
recommended that we require the
Marine Corps to: (1) Describe in detail
the method by which it determined the
zones of exposure for gunnery exercises
that use large arms; and (2) specify if
multiple types of rounds or ordnance
would be used within a single exercise
and describe in detail how it
determined the zones of exposure for
those exercises prior to issuing the
incidental harassment authorization.
Response: The Marine Corps’
application, as well as subsequent
responses provided to the Commission
describe how they derived safety zones
for gunnery exercises. The method to
estimate the number of marine
mammals potentially taken by the
specified activities is based on dolphin
density, the amount and type of
ordnance proposed, and distances to our
harassment threshold criteria.
Briefly, the Marine Corps estimate the
zones of exposure based on impulse,
peak pressure, and sound exposure level
thresholds (based on our explosive
harassment criteria). During a gunnery
exercise using large arms rounds, a
person can fire munitions as individual
rounds spaced in time, or rapid fire as
a burst of individual rounds. Due to the
tight spacing in time, the Marine Corps
treats the individual rounds within a
burst as a single detonation.
VerDate Mar<15>2010
17:55 Jul 12, 2013
Jkt 229001
the source spectrum for a single
detonation scaled by the number of
rounds in a burst.
(2) For the pressure metrics, they
calculate the impact area for a burst as
equal to the impact area of a single
round.
(3) For all metrics, the cumulative
impact area of an event consisting of (N)
bursts is the product of the impact area
of a single burst and the number of
bursts, as would be the case if the bursts
are sufficiently spaced in time or
location as to insure that each burst is
affecting a different set of marine
wildlife. Last, they model each
explosive event for potential impacts to
a derived density of marine mammals
within the influence area. They sum the
results of all individual events over the
year to obtain their take estimate.
Comment 2: The Commission also
requested that we require the Marine
Corps to implement a plan to evaluate
the effectiveness of all of its mitigation
and monitoring measures before
initiating or, at the very latest, in
conjunction with the exercises covered
by the incidental harassment
authorization (i.e., night vision
technology, remote-camera system,
visual observations during range sweeps
and cold passes).
Response: We have worked closely
with the Marine Corps over the past two
Authorization cycles to develop proper
mitigation, monitoring, and reporting
requirements designed to minimize and
detect impacts from the specified
activities. In order to ensure that we can
make the findings necessary for
issuance of an Authorization, we have
worked with the Marine Corps to
develop comprehensive and acceptable
mitigation, monitoring, and reporting
requirements including a Marine
Mammal and Protected Species
Monitoring Plan (Plan). We have
determined that the current Plan and
required monitoring and mitigation
measures within the Authorization are
adequate to satisfy the requirements of
the MMPA.
Comment 3: The Commission also
requested that we require the Marine
Corps to use the passive acoustic
monitoring system to supplement its
visual observations as soon as
practicable.
Response: The Marine Corps has
contracted Duke University to develop
and test a real-time passive acoustic
monitoring system that will allow
automated detection of bottlenose
dolphin whistles. Duke University
performed the work in two phases. First
PO 00000
Frm 00008
Fmt 4703
Sfmt 4703
developing an automated signal detector
(a software program) to recognize the
whistles of dolphins at BT–9 and BT–
11 and second assembling and
deploying a prototype for real time
monitoring. Phase II is currently in
progress and the success of this effort
will help direct future monitoring
initiatives and activities within the
MCAS Cherry Point Range Complex.
The passive acoustic monitoring unit
remains in prototype until the
contractors have completed all testing
and the Marine Corps are able to
establish a baseline of information to
develop standard operating procedures
for future activities.
Comment 4: The Commission
recommends the NMFS require the
USMC to use either direct strike or
dynamic Monte Carlo models to
determine the probability of ordnance
strike.
Response: The Commission
recommended ‘‘direct strike or dynamic
Monte Carlo methods’’ while noting that
the result of using a new risk probability
model would likely provide negligible
changes from the model described in the
application. Because any change would
be negligible, we do not agree that this
alternative method of modeling is
necessary for purposes of issuing an
MMPA incidental take authorization at
this time.
Description of Marine Mammals in the
Area of the Specified Activity
Forty marine mammal species occur
within the nearshore and offshore
waters of North Carolina; however, the
majority of these species are solely
oceanic in distribution. Of the 40
species, only one marine mammal
species, the bottlenose dolphin
(Tursiops truncatus), routinely
frequents Pamlico Sound. The
endangered West Indian manatee
(Trichechus manatus), under the
jurisdiction of the U.S. Fish and
Wildlife Service, rarely occurs in the
area (Lefebvre et al, 2001; DoN 2003).
Based on the best available data, the
Marine Corps does not expect to
encounter the following species because
of these species rare and/or extralimital
occurrence in the survey area including
the North Atlantic right whale
(Eubalaena glacialis); Atlantic spotted
dolphin (Stenella frontalis) and
common dolphin (Delphinus delphis).
Of the 40 species that may be
encountered, most are oceanic in
distribution and do not venture into the
shallow, brackish waters of southern
Pamlico Sound. No suitable habitat
exists for large whale species in the
shallow Pamlico Sound or bombing
target vicinity. Accordingly, we did not

15JYN1
Federal Register / Vol. 78, No. 135 / Monday, July 15, 2013 / Notices
tkelley on DSK3SPTVN1PROD with NOTICES
consider these other species in greater
detail. The specified activity has the
potential to affect only one marine
mammal species under our jurisdiction:
The bottlenose dolphin. We refer the
public to the previous Federal Register
notice for the proposed Authorization
(78 FR 19224, Friday, March 29, 2013)
where we present information on this
species.
Potential Effects of the Specified
Activity on Marine Mammals
As mentioned previously, with
respect to military readiness activities,
Section 3(18)(B) of the MMPA defines
‘‘harassment’’ as: (i) Any act that injures
or has the significant potential to injure
a marine mammal or marine mammal
stock in the wild [Level A Harassment];
or (ii) any act that disturbs or is likely
to disturb a marine mammal or marine
mammal stock in the wild by causing
disruption of natural behavioral
patterns, including, but not limited to,
migration, surfacing, nursing, breeding,
feeding, or sheltering, to a point where
such behavioral patterns are abandoned
or significantly altered [Level B
Harassment].
We have determined that Level B
harassment to marine mammals
(specifically bottlenose dolphins) could
occur incidental to noise and
detonations from munitions firing (all
military readiness activities) at the
bombing targets. These military
readiness activities will result in
increased noise levels, explosions, and
munitions debris within bottlenose
dolphin habitat. In the absence of
planned mitigation and monitoring
measures, it is possible that injury or
mortality of bottlenose dolphins could
occur; however, due to the
implementation of the planned
measures, we do not anticipate that
harassment would rise to the level of
injury (Level A harassment), serious
injury, or mortality. Therefore, the
Authorization solely authorizes Level B
(behavioral) harassment incidental to
the Marine Corp’s training activities. We
anticipate that bottlenose dolphins may
undergo temporary threshold shift,
masking, stress response, and altered
behavioral patterns (e.g., traveling,
resting, opportunistic foraging). The
notice for the proposed Authorization
(78 FR 19224, Friday, March 29, 2013)
provided complete description of these
impacts. In addition, we refer the reader
to our proposed and final rulemaking
for the Navy Cherry Point Range
Complex (74 FR 11057, March 16, 2009
and 74 FR 28370, June 15, 2009 for a
full assessment of marine mammal
responses and disturbances when
exposed to anthropogenic sound.
VerDate Mar<15>2010

Potential Effects of the Specified
Activity on Marine Mammal Habitat
We provided a detailed discussion of
the potential effects of this action on
marine mammal habitat in the notice for
the proposed Authorization (78 FR
19224, Friday, March 29, 2013).
Detonations of live ordnance would
result in temporary changes to the water
environment. Munitions would hit the
targets and not explode in the water.
However, because the targets are over
the water (i.e., a ship’s hull on a shoal),
in water explosions could occur. An
underwater explosion from these
weapons could send a shock wave and
blast noise through the water, release
gaseous by-products, create an
oscillating bubble, and cause a plume of
water to shoot up from the water
surface. However, these effects would be
temporary and not expected to last more
than a few seconds.
Similarly, no long term impacts with
regard to hazardous constituents are
expected to occur. MCAS Cherry Point
has an active Range Environmental
Vulnerability Assessment (REVA)
program in place to monitor impacts to
habitat from its activities. One goal of
REVA is to determine the horizontal and
vertical concentration profiles of heavy
metals, explosives constituents,
perchlorate nutrients, and dissolved
salts in the sediment and seawater
surrounding BT–9 and BT–11. The
Marine Corps has sampled the explosive
constituents (e.g., trinitrotoluene (TNT),
cyclotrimethylenetrinitramine (RDX),
and hexahydro-trinitro-triazine (HMX)
in the sediment or water sample
surrounding the BTs as described in
Hazardous Constituents [Subchapter
3.2.7.2] of the MCAS Cherry Point
Range Operations EA. At present, they
have not detected these constituents in
the sediment or water. Metals were not
present above toxicity screening values.
Perchlorate was detected in a few
sediment samples above the detection
limit (0.21 ppm), but below the
reporting limit (0.6 ppm). The ongoing
REVA would continue to evaluate
potential munitions constituent
migration from operational range areas
to off-range areas and MCAS Cherry
Point.
While we anticipate that the specified
activity may result in marine mammals
avoiding certain areas due to temporary
ensonification, this impact to habitat
and prey resources is temporary and
reversible and considered in notice for
the proposed Authorization (78 FR
19224, Friday, March 29, 2013), as
behavioral modification. The main
impact associated with the proposed
activity would be temporarily elevated

noise levels and the associated direct
effects on marine mammals, previously
discussed.
Summary of Previous Monitoring
The Marine Corps complied with the
mitigation and monitoring required
under the previous authorizations
(2010–2012). In accordance with the
2010–11 IHA, USMC submitted a final
monitoring report, which described the
activities conducted and observations
made. USMC did not record
observations of any marine mammals
during training exercises. The only
recorded observations—which were of
bottlenose dolphins—were on two
occasions by maintenance vessels
engaged in target maintenance. No
marine mammals were observed during
range sweeps, air to ground activities,
surface to surface activities (small
boats), or ad hoc via range cameras. We
refer the reader to the notice for the
proposed Authorization (78 FR 19224,
Friday, March 29, 2013) for a full
discussion of the previous monitoring
results. The Marine Corps will submit a
monitoring report for the 2012 training
season which expired on December 31,
2012, to us by June 31, 2013. We will
post the monitoring report on our Web
site https://www.nmfs.noaa.gov/pr/
permits/incidental.htm#applications.
Mitigation
In order to issue an incidental take
authorization under section 101(a)(5)(D)
of the MMPA, we 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 the availability
of such species or stock for taking for
certain subsistence uses.
The NDAA of 2004 amended the
MMPA as it relates to military-readiness
activities and the incidental take
authorization process such that ‘‘least
practicable adverse impact’’ shall
include consideration of personnel
safety, practicality of implementation,
and impact on the effectiveness of the
military readiness activity. The training
activities described in the Marine Corp’s
application are military readiness
activities.
We have evaluated the applicant’s
proposed mitigation measures and
considered other measures in the
context of ensuring that we prescribe
the means of effecting the least
practicable adverse 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: (1) The manner
in which, and the degree to which, the
successful implementation of the
measure is expected to minimize
adverse impacts to marine mammals;
(2) the proven or likely efficacy of the
specific measure to minimize adverse
impacts as planned; and (3) the
practicability of the measure for
applicant implementation, including
consideration of personnel safety,
practicality of implementation, and
impact on the effectiveness of the
military readiness activity. We have
determined that the mitigation measures
described provide the means of effecting
the least practicable adverse impacts on
marine mammal species or stocks and
their habitat, paying particular attention
to rookeries, mating grounds, and areas
of similar significance while also
considering personnel safety,
practicality of implementation, and
impact on the effectiveness of the
military readiness activity.
The Marine Corps, in collaboration
with us, has worked to identify
potential practicable and effective
mitigation measures, which include a
careful balancing of the likely benefit of
any particular measure to the marine
mammals with the likely effect of that
measure on personnel safety,
practicality of implementation, and
impact on the ‘‘military-readiness
activity.’’ These mitigation measures
include:
(1) Range Sweeps: The VMR–1
squadron, stationed at MCAS Cherry
Point, includes three specially equipped
HH–46D helicopters. The primary
mission of these aircraft, known as
PEDRO, is to provide search and rescue
for downed 2nd Marine Air Wing
aircrews. On-board are a pilot, co-pilot,
crew chief, search and rescue swimmer,
and a medical corpsman. Each crew
member has received extensive training
in search and rescue techniques, and is
therefore particularly capable at spotting
objects floating in the water.
PEDRO crew would conduct a range
sweep the morning of each exercise day
prior to the commencement of range
operations. The primary goal of the preexercise sweep is to ensure that the
target area is clear of fisherman, other
personnel, and protected species. The
sweeps occur at 100–300 meters above
the water surface, at airspeeds between
60–100 knots. The path of the sweep
runs down the western side of BT–11,
circles around BT–9 and then continues
down the eastern side of BT–9 before
leaving. The sweep typically takes 20–
30 minutes to complete. The PEDRO
crew communicates directly with range
personnel and can provide immediate
VerDate Mar<15>2010
17:55 Jul 12, 2013
Jkt 229001
notification to range operators. The
PEDRO aircraft would remain in the
area of a sighting until clear if possible
or as mission requirements dictate.
If the crew sights marine mammals
during a range sweep, they would
collect sighting data and enter it into the
U.S. Marine Corps sighting database,
web-interface, or report generator. They
would relay this information to the
training Commander. Sighting data
includes the following (collected to the
best of the observer’s ability): (1)
Species identification; (2) group size; (3)
the behavior of marine mammals (e.g.,
milling, travel, social, foraging);
(4) location and relative distance from
the BT; (5) date, time and visual
conditions (e.g., Beaufort sea state,
weather) associated with each
observation; (6) direction of travel
relative to the BT; and (7) duration of
the observation.
(2) Cold Passes: All aircraft
participating in an air-to-surface
exercise would be required to perform a
‘‘cold pass’’ immediately prior to
ordnance delivery at the BTs both day
and night. That is, prior to granting a
‘‘First Pass Hot’’ (use of ordnance),
pilots would be directed to perform a
low, cold (no ordnance delivered) first
pass which serves as a visual sweep of
the targets prior to ordnance delivery to
determine if unauthorized civilian
vessels or personnel, or protected
species, are present. They conduct the
cold pass with the aircraft (helicopter or
fixed-winged) flying straight and level at
altitudes of 200–3000 feet over the target
area. The viewing angle is
approximately 15 degrees. A blind spot
exists to the immediate rear of the
aircraft. Based upon prevailing
visibility, a pilot can see more than one
mile forward upon approach. The
aircrew and range personnel make every
attempt to ensure clearance of the area
via visual inspection and remotely
operated camera operations (see
Monitoring and Reporting section). The
Range Controller may deny or approve
the First Pass Hot clearance as
conditions warrant.
(3) Delay of Exercises: The Marine
Corps would consider an active range
‘‘fouled’’ and not available for use if a
marine mammal is present within 1,000
yards (914 m) of the target area at BT–
9 or anywhere within Rattan Bay (BT–
11). Therefore, if they observe a marine
mammal within 1,000 yards (914 m) of
the target at BT–9 or anywhere within
Rattan Bay at BT–11 during the cold
pass or from range camera detection,
they would delay training until the
marine mammal moves beyond and on
a path away from 1,000 yards (914 m)
from the BT–9 target or out of Rattan
PO 00000
Frm 00010
Fmt 4703
Sfmt 4703
Bay at BT–11. This mitigation applies to
both air-to-surface and surface-tosurface exercises.
(4) Range Camera Use: To increase
the safety of persons or property near
the targets, Range Operation and Control
personnel monitor the target area
through two tower mounted safety and
surveillance cameras. The remotely
operated range cameras are high
resolution and, according to range
personnel, allow a clear visual of a duck
floating near the target. The cameras
allow viewers to see animals at the
surface and breaking the surface, but not
underwater. The camera system has
night vision (IR) capabilities with
resolution levels almost as good as
during daytime. Lenses on the camera
system have a focal length of 250 mm
to 1500 mm, with view angle of (2.2° x
1.65° in wide-view) and (0.55° x 41° in
narrow-view) respectively. Using the
night-time capabilities, with a narrow
view, an observer could identify a 1 x
1 meter target out to three kilometers.
Again, in the event that a marine
mammal is sighted within 1000 yards
(914 m) of the BT–9 target, or anywhere
within Rattan Bay, the target would be
declared fouled. Operations may
commence in the fouled area after the
animal(s) have moved 1000 yards (914
m) from the BT–9 target and/or out of
Rattan Bay.
(5) Vessel Operation: All vessels used
during training operations would abide
by the Service’s Southeast Regional
Viewing Guidelines designed to prevent
harassment to marine mammals (https://
www.nmfs.noaa.gov/pr/education/
southeast/).
(6) Stranding Network Coordination:
The Marine Corps would coordinate
with the local NMFS Stranding
Coordinator for any unusual marine
mammal behavior and any stranding,
beached live/dead, or floating marine
mammals that may occur at any time
during training activities or within 24
hours after completion of training.
Monitoring and Reporting
In order to issue an Authorization for
an activity, section 101(a)(5)(D) of the
MMPA states that we 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 Incidental
Harassment Authorizations must
include the suggested means of
accomplishing the necessary monitoring
and reporting that will result in
increased knowledge of the species and
of the level of taking or impacts on
populations of marine mammals that are
expected to be present.

tkelley on DSK3SPTVN1PROD with NOTICES
Federal Register / Vol. 78, No. 135 / Monday, July 15, 2013 / Notices
Monitoring measures prescribed by us
should accomplish one or more of the
following general goals: (a) An increase
in our understanding of how many
marine mammals are likely to be
exposed to munitions noise and
explosions that we associate with
specific adverse effects, such as
behavioral harassment, threshold shift;
(b) an increase in our understanding of
how individual marine mammals
respond (behaviorally or
physiologically) to gunnery and
bombing exercises (at specific received
levels) expected to result in take; (c) an
increase in our understanding of how
anticipated takes of 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);
(d) an increased knowledge of the
affected species; (e) an increase in our
understanding of the effectiveness of
certain mitigation and monitoring
measures; (f) a better understanding and
record of the manner in which the
authorized entity complies with the
Authorization; and (g) an increase in the
probability of detecting marine
mammals, both within the safety zone
(thus allowing for more effective
implementation of the mitigation) and
in general.
The suggested means of
accomplishing the necessary monitoring
and reporting that will result in
increased knowledge of the species and
of the level of taking or impacts on
populations of marine mammals
expected to be present within the action
area are as follows:
(1) Protected Species Observer
Training: Pilots, operators of small
boats, and other personnel monitoring
for marine mammals would be required
to take the Marine Species Awareness
Training (Part 1 and 2), provided by the
U.S. Navy. This training would make
personnel knowledgeable of marine
mammals, protected species, and visual
cues related to the presence of marine
mammals and protected species.
(2) Weekly and Post-Exercise
Monitoring: The Marine Corps would
conduct post-exercise monitoring the
morning following an exercise, unless
an exercise occurs on a Friday, in which
case the post-exercise sweep would take
place the following Monday. Weekly
monitoring events would include a
maximum of five pre-exercise and four
post-exercise sweeps. The maximum
number of days that would elapse
between pre- and post-exercise
monitoring events would be
approximately three days, and would
normally occur on weekends. If marine
mammals are observed during this
VerDate Mar<15>2010
17:55 Jul 12, 2013
Jkt 229001
monitoring, sighting data identical to
those collected by PEDRO crew would
be recorded.
(3) Long-Term Monitoring: The
Marine Corps has awarded Duke
University Marine Lab (Duke) a contract
to obtain abundance, group dynamics
(e.g., group size, age census), behavior,
habitat use, and acoustic data on the
bottlenose dolphins which inhabit
Pamlico Sound, specifically those
around BT–9 and BT–11. Duke began
conducting boat-based surveys and
passive acoustic monitoring of
bottlenose dolphins in Pamlico Sound
in 2000 (Read et al., 2003) and
specifically at BT–9 and BT–11 in 2003
(Mayer, 2003). To date, boat-based
surveys indicate that bottlenose
dolphins may be resident to Pamlico
Sound and use BT restricted areas on a
frequent basis. Passive acoustic
monitoring (PAM) provides more
detailed insight into how dolphins use
the two ranges, by monitoring for their
vocalizations year-round, regardless of
weather conditions or darkness. In
addition to these surveys, Duke
scientists are testing a real-time passive
acoustic monitoring system at BT–9 that
will allow automated detection of
bottlenose dolphin whistles, providing
yet another method of detecting
dolphins prior to training operations.
Although it is unlikely this PAM system
would be active for purposes of
implementing mitigation measures
before an exercise prior to expiration of
the proposed Authorization, it could be
operational for future MMPA incidental
take authorizations and would be
evaluated for effectiveness at the
appropriate time.
(4) Reporting: The Marine Corps will
submit a report to us within 90 days
after expiration of the Authorization or,
if a subsequent incidental take
authorization is requested, within 120
days prior to expiration of the
Authorization. The report will
summarize the type and amount of
training exercises conducted, all marine
mammal observations made during
monitoring, and if mitigation measures
were implemented. The report will also
address the effectiveness of the
monitoring plan in detecting marine
mammals.
General Notification of Injured or Dead
Marine Mammals
The Marine Corps will systematically
observe training operations for injured
or disabled marine mammals. In
addition, the Marine Corps would
monitor the principal marine mammal
stranding networks and other media to
correlate analysis of any dolphin
strandings that could potentially be
PO 00000
Frm 00011
Fmt 4703

associated with Cherry Point training
operations.
Marine Corps personnel will ensure
that we are notified immediately or as
soon as clearance procedures allow if an
injured, stranded, or dead marine
mammal is found during or shortly
after, and in the vicinity of, any training
operations. The Marine Corps will
provide us with species or description
of the animal(s), the condition of the
animal(s) (including carcass condition if
the animal is dead), location, time of
first discovery, observed behaviors (if
alive), and photo or video (if available).
In the event that an injured, stranded,
or dead marine mammal is found by
Marine Corps personnel that is not in
the vicinity of, or found during or
shortly after operations, the Marine
Corps personnel will report the same
information as listed above as soon as
operationally feasible and clearance
procedures allow.
General Notification of a Ship Strike
In the event of a vessel strike, at any
time or place, the Marine Corps shall do
the following:
• Immediately report to us the species
identification (if known), location (lat/
long) of the animal (or the strike if the
animal has disappeared), and whether
the animal is alive or dead (or
unknown);
• Report to us as soon as
operationally feasible the size and
length of the animal, an estimate of the
injury status (e.g., dead, injured but
alive, injured and moving, unknown,
etc.), vessel class/type and operational
status;
• Report to us the vessel length,
speed, and heading as soon as feasible;
and
• Provide us a photo or video, if
equipment is available.
Estimated Take by Incidental
Harassment
The following provides the Marine
Corps’ model for take of dolphins from
explosives (without consideration of
mitigation and the conservative
assumption that all explosives would
land in the water and not on the targets
or land) and potential for direct hits and
our analysis of potential harassment
from small vessel and aircraft
operations.
The method to estimate the number of
marine mammals potentially taken by
the specified activities is based on
bottlenose dolphin density, the amount
and type of ordnance proposed, and
distances to our harassment threshold
criteria. We refer the reader to the notice
for the proposed Authorization (78 FR
19224, Friday, March 29, 2013) for a

In order to calculate take, the Marine
Corps considered the distances to which
animals could be harassed along with
dolphin density. They used the density
estimate from Read et al. (2003) to
calculate take from munitions firing
(0.183/square kilometer (km2)) and
based take calculations for munitions
firing on 100 percent water detonation.
VerDate Mar<15>2010

Because the goal of training is to hit the
targets and not the water, we consider
these take estimates based on 100
percent water detonation of munitions
to be conservative.
Based on dolphin density and amount
of munitions expended, there is very
low potential for Level A harassment,
serious injury, and mortality and

Take From Direct Hit
As described in the notice for the
proposed Authorization (78 FR 19224,
Friday, March 29, 2013), we estimate
that the potential risk of a direct hit to
an animal in the target area is
discountable. The probability of hitting
a bottlenose dolphin at the BTs can be
derived as follows: Probability =
dolphin’s dorsal surface area times the
density of dolphins. The estimated
dorsal surface area of a bottlenose
dolphin is 1.425 m2 (or the average
length of 2.85 m times the average body
width of 0.5 m). Thus, using Read et al.
(2003)’s density estimate of 0.183
dolphins/km2, without consideration of
mitigation and monitoring
implementation, the probability of a
dolphin being hit within BT–9 is 2.61 x
10¥7 and within BT–11 is 9.4 x 10¥8.
Using the proposed levels of ordnance
expenditures at each in-water BT (78 FR
19224, Friday, March 29, 2013) and
taking into account that only 36 percent
of the ordnance deployed at BT–11 is
over water, as described in the
application, the estimated potential
number of ordnance strikes on a marine
mammal per year is 0.263 at BT–9 and
0.034 at BT–11. It would take
approximately three years of ordnance
deployment at the BTs before it would
be likely or probable that one bottlenose
dolphin would be struck by deployed
inert ordnance. Again, these estimates
are without consideration to proposed
monitoring and mitigation measures.
The Marine Corps proposed three
methods of exercise monitoring (i.e.,
PEDRO, cold pass, and range cameras).
When considering the implementation
of the mitigation and monitoring
measures, the chance of a marine
mammal being taken by direct hit is
discountable.
Take From Vessel and Aircraft Presence
Interactions with vessels are not a
new experience for bottlenose dolphins
in Pamlico Sound. Pamlico Sound is
heavily used by recreational,
VerDate Mar<15>2010
17:55 Jul 12, 2013
Jkt 229001
commercial (fishing, daily ferry service,
tugs, etc.), and military (including the
Navy, Air Force, and Coast Guard)
vessels year-round. The NMFS’
Southeast Regional Office has
developed marine mammal viewing
guidelines to educate the public on how
to responsibly view marine mammals in
the wild and avoid causing a take
(https://www.nmfs.noaa.gov/pr/
education/southeast). The guidelines
recommend that vessels should remain
a minimum of 50 yards from a dolphin,
operate vessels in a predictable manner,
avoid excessive speed or sudden
changes in speed or direction in the
vicinity of animals, and not to pursue,
chase, or separate a group of animals.
The Marine Corps would abide by these
guidelines to the fullest extent
practicable. The Marine Corps would
not engage in high speed exercises
should a marine mammal be detected
within the immediate area of the BTs
prior to training commencement and
would never closely approach, chase, or
pursue dolphins. Detection of marine
mammals would be facilitated by
personnel monitoring on the vessels and
those marking success rate of target hits
and monitoring of remote camera on the
BTs (see Monitoring and Reporting
section).
Based on the description of the action,
the other activities regularly occurring
in the area, the species that may be
exposed to the activity and their
observed behaviors in the presence of
vessel traffic, and the implementation of
measures to avoid vessel strikes, we
determined that it is unlikely that the
operation of vessels during surface-tosurface maneuvers will result in the take
of any marine mammals, in the form of
either behavioral harassment, injury,
serious injury, or mortality.
Aircraft would move swiftly through
the area and would typically fly
approximately 914 m (2,998.7 ft) from
the water’s surface before dropping
unguided munitions and above 4,572 m
(2.8 miles) for precision-guided
munitions bombing. While the aircraft
PO 00000
Frm 00013
Fmt 4703
Sfmt 4703
may approach as low as 152 m (500 ft)
to drop a bomb this is not the norm and
would never been done around marine
mammals. Regional whale watching
guidelines advise aircraft to maintain a
minimum altitude of 300 m (1,000 ft)
above all marine mammals, including
small odontocetes, and to not circle or
hover over the animals to avoid
harassment. Our approach regulations
limit aircraft from flying below 300 m
(1,000 ft) over a humpback whale
(Megaptera novaeangliae) in Hawaii, a
known calving ground, and limit aircraft
from flying over North Atlantic right
whales closer than 460 m (1,509 ft).
Given that Marine Corps aircraft would
not fly below 300 m (984 ft) on the
approach, would not engage in hovering
or circling the animals, and would not
drop to the minimal altitude of 152 m
(500 ft) if a marine mammal is in the
area, we believe it unlikely that the
operation of aircraft, as described above,
will result in take of bottlenose dolphins
in Pamlico Sound in any manner.
Negligible Impact Analysis and
Determination
Pursuant to our regulations
implementing the MMPA, an applicant
is required to estimate the number of
animals that will be ‘‘taken’’ by the
specified activities (i.e., takes by
harassment only, or takes by
harassment, injury, and/or death). This
estimate informs the analysis that we
must perform to determine whether the
activity will have a ‘‘negligible impact’’
on the species or stock. We have 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.’’
A negligible impact finding is based on
the lack of likely adverse effects on
annual rates of recruitment or survival
(i.e., population-level effects). An
estimate of the number and manner of
takes, alone, is not enough information
E:\FR\FM\15JYN1.SGM
15JYN1
tkelley on DSK3SPTVN1PROD with NOTICES
42050
Federal Register / Vol. 78, No. 135 / Monday, July 15, 2013 / Notices
on which to base a negligible impact
determination. We must also 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.), or any of the
other variables mentioned in the first
paragraph (if known), as well as the
number and nature of estimated Level A
takes, the number of estimated
mortalities, and effects on habitat.
The Marine Corps has conducted
gunnery and bombing training exercises
at BT–9 and BT–11 for several years
and, to date, the monitoring reports
indicate that no dolphin injury, serious
injury, or mortality has been attributed
to these military training exercises. The
Marine Corps has a history of notifying
the NMFS stranding network when any
injured or stranded animal comes
ashore or is spotted by personnel on the
water. Therefore, stranded animals have
been examined by stranding responders,
further confirming that it is unlikely
training contributes to marine mammal
injuries or deaths. Due to the
implementation of the aforementioned
proposed mitigation measures, no take
by Level A harassment or serious injury
or mortality is anticipated nor would
any be authorized in the IHA. We are
proposing, however, to authorize 25
Level B harassment takes associated
with training exercises.
The Marine Corps has proposed a
1,000 yard (914 m) safety zone around
BT–9 despite the fact that the distance
to our explosive Level B harassment
threshold is 228 yards (209 m). They
also would consider an area fouled if
any dolphins are spotted within Raritan
Bay (where BT–11 is located)—
triggering a shutdown of activities in
that area. The Level B harassment takes
allowed for in the Authorization would
be of very low intensity and would
likely result in dolphins being
temporarily behaviorally affected by
bombing or gunnery exercises. In
addition, takes may be attributed to
animals not using the area when
exercises are occurring; however, this is
difficult to calculate. Instead, we look if
the specified activities occur during and
within habitat important to vital life
functions to better inform its negligible
impact determination.
Read et al. (2003) concluded that
dolphins rarely occur in open waters in
the middle of North Carolina sounds
and large estuaries, but instead are
concentrated in shallow water habitats
along shorelines. However, no specific
areas have been identified as vital

that dolphins use the areas around the
BTs more frequently than other portions
of Pamlico Sound (Maher, 2003) despite
the Marine Corps actively training in a
manner identical to the specified
activities described here for years.
As described in the Affected Species
section of this notice, bottlenose
dolphin stock segregation is complex
with stocks overlapping throughout the
coastal and estuarine waters of North
Carolina. It is not possible for the
Marine Corps to determine to which
stock any individual dolphin taken
during training activities belong as this
can only be accomplished through
genetic testing. However, it is likely that
many of the dolphins encountered
would belong to the Northern or
Southern North Carolina Estuarine
System stocks. These stocks have
abundance estimates of 950 and 2,454,
respectively. We authorize 25 takes of
bottlenose dolphins in total; therefore,
this number represents 2.6 and 1.0
percent, respectively, of those
populations. This species is not listed as
threatened or endangered under the
ESA.
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, we
find that the specified USMC Air
Station Cherry Point BT–9 and BT–11
training activities would result in the
incidental take of marine mammals, by
Level B harassment only, and that the
total taking from would have a
negligible impact on the affected species
or stocks.
Subsistence Harvest of Marine
Mammals
Marine mammals are not taken for
subsistence uses within Pamlico Sound;
therefore, issuance of an IHA to the
USMC for MCAS Cherry Point training
exercises would not have an
unmitigable adverse impact on the
availability of the affected species or
stocks for subsistence use.
Endangered Species Act (ESA)
No ESA-listed marine mammals are
known to occur within the action area.
Therefore, there is no requirement for us
to consult under Section 7 of the ESA
on the issuance of an Authorization
under section 101(a)(5)(D) of the
MMPA. However, ESA-listed sea turtles
may be present within the action area.
On September 27, 2002, NMFS issued
a Biological Opinion (BiOp) on Ongoing
Ordnance Delivery at Bombing Target 9

Point, North Carolina. The BiOp, which
is still in effect, concluded that that the
USMC’s proposed action will not result
in adverse impacts to any ESA-listed
marine mammals and is not likely to
jeopardize the continued existence of
the endangered green turtle (Chelonia
mydas), leatherback turtle (Dermochelys
coriacea), Kemp’s ridley turtle
(Lepidochelys kempii), or threatened
loggerhead turtle (Caretta caretta). The
Authorization will not result in effects
beyond those considered in the 2002
BiOp and we do not anticipate the need
for further Section 7 consultation for the
Authorization or the underlying
activities proposed by the Marine Corps.
No critical habitat has been designated
for these species in the action area;
therefore, none will be affected.
National Environmental Policy Act
(NEPA)
On February 11, 2009, the Marine
Corps issued a Finding of No Significant
Impact for its Environmental
Assessment (EA) on MCAS Cherry Point
Range Operations. Based on the analysis
of the EA, the Marine Corps determined
that the proposed action will not have
a significant impact on the human
environment. We adopted the Marine
Corps’ EA and signed a Finding of No
Significant Impact on August 31, 2010.
We have again reviewed the proposed
application and public comments and
determined that there are no substantial
changes to the proposed action or new
environmental impacts or concerns.
Therefore, we have determined that a
new or supplemental EA or
Environmental Impact Statement is
unnecessary. The EA referenced above
is available for review at https://

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 authorize, 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.
We shall grant authorization for the incidental taking of small
numbers of marine mammals if we find 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
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. We have 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.''
Section 101(a)(5)(D) of the MMPA established an expedited process
by which citizens of the United States can apply for an authorization
to incidentally take small numbers of marine mammals by harassment.
Section 101(a)(5)(D) of the MMPA establishes a 45-day time limit for
our review of an application followed by a 30-day public notice and
comment period on any proposed authorizations for the incidental
harassment of small numbers of marine mammals. Within 45 days of the
close of the public comment period, we must either issue or deny the
authorization and must publish a notice in the Federal Register within
30 days of our determination to issue or deny the authorization.
The National Defense Authorization Act of 2004 (NDAA; (Pub. L. 108-
136)) amended section 101(a)(5)(A) of the MMPA by removing the small
numbers and specified geographic region provisions; revising the
definition of harassment as it applies to a military readiness
activity; and explicitly requiring that our determination of ``least
practicable adverse impact'' include consideration of: (1) Personnel
safety; (2) the practicality of implementation; and (3) impact on the
[[Page 42043]]
effectiveness of the military readiness activity.
The NDAA's definition of harassment as it applies to a military
readiness activity is: (i) Any act that injures or has the significant
potential to injure a marine mammal or marine mammal stock in the wild
[Level A Harassment]; or (ii) any act that disturbs or is likely to
disturb a marine mammal or marine mammal stock in the wild by causing
disruption of natural behavioral patterns, including, but not limited
to, migration, surfacing, nursing, breeding, feeding, or sheltering, to
a point where such behavioral patterns are abandoned or significantly
altered [Level B Harassment].
Summary of Request
We received a request from the Marine Corps on January 28, 2013,
requesting that we issue an Incidental Harassment Authorization
(Authorization) for the take, by Level B harassment only, of small
numbers of Atlantic bottlenose dolphins (Tursiops truncatus) incidental
to air-to-surface and surface-to-surface training exercises conducted
around two bombing targets within southern Pamlico Sound, North
Carolina, at Marine Corps Air Station Cherry Point. We received a
complete and adequate application on March 19, 2013 and released the
application for public comment (see ADDRESSES) for consideration of
issuing an Authorization to the USMC. To date, we have issued two, 1-
year Authorizations to the Marine Corps for the conduct of the same
activities from 2010 to 2012 (75 FR 72807, November 26, 2010; 77 FR
January 3, 2012).
Description of the Specified Activity
The Marine Corps plan to conduct weapon delivery training at two
bombing targets: Brant Island Target (BT-9) and Piney Island Bombing
Range (BT-11) within MCAS Cherry Point Range Complex, located within
Pamlico Sound, North Carolina. The two targets are located at the
convergence of the Neuse River and Pamlico Sound.
Training at BT-9 would involve air-to-surface (from aircraft to in-
water targets) and surface-to-surface (from vessels to in-water
targets) warfare training, including bombing, strafing, special (laser
systems) weapons; surface fires using non-explosive and explosive
ordnance; and mine laying exercises (inert). Training at BT-11 would
involve air- to-surface exercises to provide training in the delivery
of conventional (non-explosive) and special (laser systems) weapons.
Surface-to-surface training by small military watercraft would also be
executed here. The types of ordnances proposed for use at BT-9 and BT-
11 include small arms, large arms, bombs, rockets, missiles, and
pyrotechnics. All munitions used at BT-11 are inert, practice rounds
and no live firing would occur at BT-11. Training for any activity may
occur year-round.
The Marine Corps requested authorization to harass bottlenose
dolphins from firing exercises conducted at two bombing targets within
MCAS Cherry Point Range Complex, located within Pamlico Sound, North
Carolina at the convergence of the Neuse River and Pamlico Sound. These
activities include gunnery; mine laying; bombing; or rocket exercises
and are classified into two categories here based on delivery method:
(1) Surface-to-surface gunnery and (2) air-to-surface bombing. Active
sonar is not a component of these specified training exercises.
Exercises may occur year round, day or night (approximately 15
percent of training occurs at night). The Marine Corps would conduct
all inert and live-fire exercises so that all ammunition and other
ordnances strike and/or fall on the land or water based target or
within the existing danger zones or water restricted areas.
Acoustic stimuli (i.e., increased underwater sound) generated
during the training exercises, may have the potential to cause
behavioral disturbance for marine mammals in BT-9 and BT-11. This is
the principal means of marine mammal taking associated with these
activities. We expect these disturbances to be temporary and result in
a temporary modification in behavior and/or low-level physiological
effects (Level B harassment only) of small numbers of certain species
of marine mammals.
We have outlined the purpose of the program in a previous notice
for the proposed Authorization (78 FR 19224, Friday, March 29, 2013).
Refer to the notice of the proposed Authorization (78 FR 19224, Friday,
March 29, 2013), the application, and the Marine Corps' EA for a more
detailed description of the authorized action.
The amounts of all ordnance to be expended at BT-9 and BT-11 (both
surface-to-surface and air-to-surface) are 1,225,815 and 1,254,684
rounds, respectively (see Table 1 and 2).

Comments and Responses
We published a notice of receipt of the Marine Corps' application
and proposed Authorization in the Federal Register on Friday, March 29,
2013 (78 FR 19224). During the 30-day public comment period, we
received comments from the Marine Mammal Commission (Commission) and
four private citizens. These comments are online at: https://www.nmfs.noaa.gov/pr/permits/incidental.htm. Following are the comments
and our responses.
Comment 1: The Commission recommended that we require the Marine
Corps to: (1) Describe in detail the method by which it determined the
zones of exposure for gunnery exercises that use large arms; and (2)
specify if multiple types of rounds or ordnance would be used within a
single exercise and describe in detail how it determined the zones of
exposure for those exercises prior to issuing the incidental harassment
authorization.
Response: The Marine Corps' application, as well as subsequent
responses provided to the Commission describe how they derived safety
zones for gunnery exercises. The method to estimate the number of
marine mammals potentially taken by the specified activities is based
on dolphin density, the amount and type of ordnance proposed, and
distances to our harassment threshold criteria.
Briefly, the Marine Corps estimate the zones of exposure based on
impulse, peak pressure, and sound exposure level thresholds (based on
our explosive harassment criteria). During a gunnery exercise using
large arms rounds, a person can fire munitions as individual rounds
spaced in time, or rapid fire as a burst of individual rounds. Due to
the tight spacing in time, the Marine Corps treats the individual
rounds within a burst as a single detonation.
(1) For the energy metrics, they calculate the impact area of a
burst using a source energy spectrum that is the source spectrum for a
single detonation scaled by the number of rounds in a burst.
(2) For the pressure metrics, they calculate the impact area for a
burst as equal to the impact area of a single round.
(3) For all metrics, the cumulative impact area of an event
consisting of (N) bursts is the product of the impact area of a single
burst and the number of bursts, as would be the case if the bursts are
sufficiently spaced in time or location as to insure that each burst is
affecting a different set of marine wildlife. Last, they model each
explosive event for potential impacts to a derived density of marine
mammals within the influence area. They sum the results of all
individual events over the year to obtain their take estimate.
Comment 2: The Commission also requested that we require the Marine
Corps to implement a plan to evaluate the effectiveness of all of its
mitigation and monitoring measures before initiating or, at the very
latest, in conjunction with the exercises covered by the incidental
harassment authorization (i.e., night vision technology, remote-camera
system, visual observations during range sweeps and cold passes).
Response: We have worked closely with the Marine Corps over the
past two Authorization cycles to develop proper mitigation, monitoring,
and reporting requirements designed to minimize and detect impacts from
the specified activities. In order to ensure that we can make the
findings necessary for issuance of an Authorization, we have worked
with the Marine Corps to develop comprehensive and acceptable
mitigation, monitoring, and reporting requirements including a Marine
Mammal and Protected Species Monitoring Plan (Plan). We have determined
that the current Plan and required monitoring and mitigation measures
within the Authorization are adequate to satisfy the requirements of
the MMPA.
Comment 3: The Commission also requested that we require the Marine
Corps to use the passive acoustic monitoring system to supplement its
visual observations as soon as practicable.
Response: The Marine Corps has contracted Duke University to
develop and test a real-time passive acoustic monitoring system that
will allow automated detection of bottlenose dolphin whistles. Duke
University performed the work in two phases. First developing an
automated signal detector (a software program) to recognize the
whistles of dolphins at BT-9 and BT-11 and second assembling and
deploying a prototype for real time monitoring. Phase II is currently
in progress and the success of this effort will help direct future
monitoring initiatives and activities within the MCAS Cherry Point
Range Complex. The passive acoustic monitoring unit remains in
prototype until the contractors have completed all testing and the
Marine Corps are able to establish a baseline of information to develop
standard operating procedures for future activities.
Comment 4: The Commission recommends the NMFS require the USMC to
use either direct strike or dynamic Monte Carlo models to determine the
probability of ordnance strike.
Response: The Commission recommended ``direct strike or dynamic
Monte Carlo methods'' while noting that the result of using a new risk
probability model would likely provide negligible changes from the
model described in the application. Because any change would be
negligible, we do not agree that this alternative method of modeling is
necessary for purposes of issuing an MMPA incidental take authorization
at this time.
Description of Marine Mammals in the Area of the Specified Activity
Forty marine mammal species occur within the nearshore and offshore
waters of North Carolina; however, the majority of these species are
solely oceanic in distribution. Of the 40 species, only one marine
mammal species, the bottlenose dolphin (Tursiops truncatus), routinely
frequents Pamlico Sound. The endangered West Indian manatee (Trichechus
manatus), under the jurisdiction of the U.S. Fish and Wildlife Service,
rarely occurs in the area (Lefebvre et al, 2001; DoN 2003).
Based on the best available data, the Marine Corps does not expect
to encounter the following species because of these species rare and/or
extralimital occurrence in the survey area including the North Atlantic
right whale (Eubalaena glacialis); Atlantic spotted dolphin (Stenella
frontalis) and common dolphin (Delphinus delphis). Of the 40 species
that may be encountered, most are oceanic in distribution and do not
venture into the shallow, brackish waters of southern Pamlico Sound. No
suitable habitat exists for large whale species in the shallow Pamlico
Sound or bombing target vicinity. Accordingly, we did not
[[Page 42045]]
consider these other species in greater detail. The specified activity
has the potential to affect only one marine mammal species under our
jurisdiction: The bottlenose dolphin. We refer the public to the
previous Federal Register notice for the proposed Authorization (78 FR
19224, Friday, March 29, 2013) where we present information on this
species.
Potential Effects of the Specified Activity on Marine Mammals
As mentioned previously, with respect to military readiness
activities, Section 3(18)(B) of the MMPA defines ``harassment'' as: (i)
Any act that injures or has the significant potential to injure a
marine mammal or marine mammal stock in the wild [Level A Harassment];
or (ii) any act that disturbs or is likely to disturb a marine mammal
or marine mammal stock in the wild by causing disruption of natural
behavioral patterns, including, but not limited to, migration,
surfacing, nursing, breeding, feeding, or sheltering, to a point where
such behavioral patterns are abandoned or significantly altered [Level
B Harassment].
We have determined that Level B harassment to marine mammals
(specifically bottlenose dolphins) could occur incidental to noise and
detonations from munitions firing (all military readiness activities)
at the bombing targets. These military readiness activities will result
in increased noise levels, explosions, and munitions debris within
bottlenose dolphin habitat. In the absence of planned mitigation and
monitoring measures, it is possible that injury or mortality of
bottlenose dolphins could occur; however, due to the implementation of
the planned measures, we do not anticipate that harassment would rise
to the level of injury (Level A harassment), serious injury, or
mortality. Therefore, the Authorization solely authorizes Level B
(behavioral) harassment incidental to the Marine Corp's training
activities. We anticipate that bottlenose dolphins may undergo
temporary threshold shift, masking, stress response, and altered
behavioral patterns (e.g., traveling, resting, opportunistic foraging).
The notice for the proposed Authorization (78 FR 19224, Friday, March
29, 2013) provided complete description of these impacts. In addition,
we refer the reader to our proposed and final rulemaking for the Navy
Cherry Point Range Complex (74 FR 11057, March 16, 2009 and 74 FR
28370, June 15, 2009 for a full assessment of marine mammal responses
and disturbances when exposed to anthropogenic sound.
Potential Effects of the Specified Activity on Marine Mammal Habitat
We provided a detailed discussion of the potential effects of this
action on marine mammal habitat in the notice for the proposed
Authorization (78 FR 19224, Friday, March 29, 2013). Detonations of
live ordnance would result in temporary changes to the water
environment. Munitions would hit the targets and not explode in the
water. However, because the targets are over the water (i.e., a ship's
hull on a shoal), in water explosions could occur. An underwater
explosion from these weapons could send a shock wave and blast noise
through the water, release gaseous by-products, create an oscillating
bubble, and cause a plume of water to shoot up from the water surface.
However, these effects would be temporary and not expected to last more
than a few seconds.
Similarly, no long term impacts with regard to hazardous
constituents are expected to occur. MCAS Cherry Point has an active
Range Environmental Vulnerability Assessment (REVA) program in place to
monitor impacts to habitat from its activities. One goal of REVA is to
determine the horizontal and vertical concentration profiles of heavy
metals, explosives constituents, perchlorate nutrients, and dissolved
salts in the sediment and seawater surrounding BT-9 and BT-11. The
Marine Corps has sampled the explosive constituents (e.g.,
trinitrotoluene (TNT), cyclotrimethylenetrinitramine (RDX), and
hexahydro-trinitro-triazine (HMX) in the sediment or water sample
surrounding the BTs as described in Hazardous Constituents [Subchapter
3.2.7.2] of the MCAS Cherry Point Range Operations EA. At present, they
have not detected these constituents in the sediment or water. Metals
were not present above toxicity screening values. Perchlorate was
detected in a few sediment samples above the detection limit (0.21
ppm), but below the reporting limit (0.6 ppm). The ongoing REVA would
continue to evaluate potential munitions constituent migration from
operational range areas to off-range areas and MCAS Cherry Point.
While we anticipate that the specified activity may result in
marine mammals avoiding certain areas due to temporary ensonification,
this impact to habitat and prey resources is temporary and reversible
and considered in notice for the proposed Authorization (78 FR 19224,
Friday, March 29, 2013), as behavioral modification. The main impact
associated with the proposed activity would be temporarily elevated
noise levels and the associated direct effects on marine mammals,
previously discussed.
Summary of Previous Monitoring
The Marine Corps complied with the mitigation and monitoring
required under the previous authorizations (2010-2012). In accordance
with the 2010-11 IHA, USMC submitted a final monitoring report, which
described the activities conducted and observations made. USMC did not
record observations of any marine mammals during training exercises.
The only recorded observations--which were of bottlenose dolphins--were
on two occasions by maintenance vessels engaged in target maintenance.
No marine mammals were observed during range sweeps, air to ground
activities, surface to surface activities (small boats), or ad hoc via
range cameras. We refer the reader to the notice for the proposed
Authorization (78 FR 19224, Friday, March 29, 2013) for a full
discussion of the previous monitoring results. The Marine Corps will
submit a monitoring report for the 2012 training season which expired
on December 31, 2012, to us by June 31, 2013. We will post the
monitoring report on our Web site https://www.nmfs.noaa.gov/pr/permits/incidental.htm#applications.
Mitigation
In order to issue an incidental take authorization under section
101(a)(5)(D) of the MMPA, we 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 the availability of such species or
stock for taking for certain subsistence uses.
The NDAA of 2004 amended the MMPA as it relates to military-
readiness activities and the incidental take authorization process such
that ``least practicable adverse impact'' shall include consideration
of personnel safety, practicality of implementation, and impact on the
effectiveness of the military readiness activity. The training
activities described in the Marine Corp's application are military
readiness activities.
We have evaluated the applicant's proposed mitigation measures and
considered other measures in the context of ensuring that we prescribe
the means of effecting the least practicable adverse impact on the
affected marine mammal species and stocks and their habitat. Our
evaluation of potential measures included
[[Page 42046]]
consideration of the following factors in relation to one another: (1)
The manner in which, and the degree to which, the successful
implementation of the measure is expected to minimize adverse impacts
to marine mammals; (2) the proven or likely efficacy of the specific
measure to minimize adverse impacts as planned; and (3) the
practicability of the measure for applicant implementation, including
consideration of personnel safety, practicality of implementation, and
impact on the effectiveness of the military readiness activity. We have
determined that the mitigation measures described provide the means of
effecting the least practicable adverse impacts on marine mammal
species or stocks and their habitat, paying particular attention to
rookeries, mating grounds, and areas of similar significance while also
considering personnel safety, practicality of implementation, and
impact on the effectiveness of the military readiness activity.
The Marine Corps, in collaboration with us, has worked to identify
potential practicable and effective mitigation measures, which include
a careful balancing of the likely benefit of any particular measure to
the marine mammals with the likely effect of that measure on personnel
safety, practicality of implementation, and impact on the ``military-
readiness activity.'' These mitigation measures include:
(1) Range Sweeps: The VMR-1 squadron, stationed at MCAS Cherry
Point, includes three specially equipped HH-46D helicopters. The
primary mission of these aircraft, known as PEDRO, is to provide search
and rescue for downed 2nd Marine Air Wing aircrews. On-board are a
pilot, co-pilot, crew chief, search and rescue swimmer, and a medical
corpsman. Each crew member has received extensive training in search
and rescue techniques, and is therefore particularly capable at
spotting objects floating in the water.
PEDRO crew would conduct a range sweep the morning of each exercise
day prior to the commencement of range operations. The primary goal of
the pre-exercise sweep is to ensure that the target area is clear of
fisherman, other personnel, and protected species. The sweeps occur at
100-300 meters above the water surface, at airspeeds between 60-100
knots. The path of the sweep runs down the western side of BT-11,
circles around BT-9 and then continues down the eastern side of BT-9
before leaving. The sweep typically takes 20-30 minutes to complete.
The PEDRO crew communicates directly with range personnel and can
provide immediate notification to range operators. The PEDRO aircraft
would remain in the area of a sighting until clear if possible or as
mission requirements dictate.
If the crew sights marine mammals during a range sweep, they would
collect sighting data and enter it into the U.S. Marine Corps sighting
database, web-interface, or report generator. They would relay this
information to the training Commander. Sighting data includes the
following (collected to the best of the observer's ability): (1)
Species identification; (2) group size; (3) the behavior of marine
mammals (e.g., milling, travel, social, foraging); (4) location and
relative distance from the BT; (5) date, time and visual conditions
(e.g., Beaufort sea state, weather) associated with each observation;
(6) direction of travel relative to the BT; and (7) duration of the
observation.
(2) Cold Passes: All aircraft participating in an air-to-surface
exercise would be required to perform a ``cold pass'' immediately prior
to ordnance delivery at the BTs both day and night. That is, prior to
granting a ``First Pass Hot'' (use of ordnance), pilots would be
directed to perform a low, cold (no ordnance delivered) first pass
which serves as a visual sweep of the targets prior to ordnance
delivery to determine if unauthorized civilian vessels or personnel, or
protected species, are present. They conduct the cold pass with the
aircraft (helicopter or fixed-winged) flying straight and level at
altitudes of 200-3000 feet over the target area. The viewing angle is
approximately 15 degrees. A blind spot exists to the immediate rear of
the aircraft. Based upon prevailing visibility, a pilot can see more
than one mile forward upon approach. The aircrew and range personnel
make every attempt to ensure clearance of the area via visual
inspection and remotely operated camera operations (see Monitoring and
Reporting section). The Range Controller may deny or approve the First
Pass Hot clearance as conditions warrant.
(3) Delay of Exercises: The Marine Corps would consider an active
range ``fouled'' and not available for use if a marine mammal is
present within 1,000 yards (914 m) of the target area at BT-9 or
anywhere within Rattan Bay (BT-11). Therefore, if they observe a marine
mammal within 1,000 yards (914 m) of the target at BT-9 or anywhere
within Rattan Bay at BT-11 during the cold pass or from range camera
detection, they would delay training until the marine mammal moves
beyond and on a path away from 1,000 yards (914 m) from the BT-9 target
or out of Rattan Bay at BT-11. This mitigation applies to both air-to-
surface and surface-to-surface exercises.
(4) Range Camera Use: To increase the safety of persons or property
near the targets, Range Operation and Control personnel monitor the
target area through two tower mounted safety and surveillance cameras.
The remotely operated range cameras are high resolution and, according
to range personnel, allow a clear visual of a duck floating near the
target. The cameras allow viewers to see animals at the surface and
breaking the surface, but not underwater. The camera system has night
vision (IR) capabilities with resolution levels almost as good as
during daytime. Lenses on the camera system have a focal length of 250
mm to 1500 mm, with view angle of (2.2[deg] x 1.65[deg] in wide-view)
and (0.55[deg] x 41[deg] in narrow-view) respectively. Using the night-
time capabilities, with a narrow view, an observer could identify a 1 x
1 meter target out to three kilometers.
Again, in the event that a marine mammal is sighted within 1000
yards (914 m) of the BT-9 target, or anywhere within Rattan Bay, the
target would be declared fouled. Operations may commence in the fouled
area after the animal(s) have moved 1000 yards (914 m) from the BT-9
target and/or out of Rattan Bay.
(5) Vessel Operation: All vessels used during training operations
would abide by the Service's Southeast Regional Viewing Guidelines
designed to prevent harassment to marine mammals (https://www.nmfs.noaa.gov/pr/education/southeast/).
(6) Stranding Network Coordination: The Marine Corps would
coordinate with the local NMFS Stranding Coordinator for any unusual
marine mammal behavior and any stranding, beached live/dead, or
floating marine mammals that may occur at any time during training
activities or within 24 hours after completion of training.
Monitoring and Reporting
In order to issue an Authorization for an activity, section
101(a)(5)(D) of the MMPA states that we 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 Incidental Harassment Authorizations must include the
suggested means of accomplishing the necessary monitoring and reporting
that will result in increased knowledge of the species and of the level
of taking or impacts on populations of marine mammals that are expected
to be present.
[[Page 42047]]
Monitoring measures prescribed by us should accomplish one or more
of the following general goals: (a) An increase in our understanding of
how many marine mammals are likely to be exposed to munitions noise and
explosions that we associate with specific adverse effects, such as
behavioral harassment, threshold shift; (b) an increase in our
understanding of how individual marine mammals respond (behaviorally or
physiologically) to gunnery and bombing exercises (at specific received
levels) expected to result in take; (c) an increase in our
understanding of how anticipated takes of 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); (d) an increased knowledge of the affected species; (e) an
increase in our understanding of the effectiveness of certain
mitigation and monitoring measures; (f) a better understanding and
record of the manner in which the authorized entity complies with the
Authorization; and (g) an increase in the probability of detecting
marine mammals, both within the safety zone (thus allowing for more
effective implementation of the mitigation) and in general.
The suggested means of accomplishing the necessary monitoring and
reporting that will result in increased knowledge of the species and of
the level of taking or impacts on populations of marine mammals
expected to be present within the action area are as follows:
(1) Protected Species Observer Training: Pilots, operators of small
boats, and other personnel monitoring for marine mammals would be
required to take the Marine Species Awareness Training (Part 1 and 2),
provided by the U.S. Navy. This training would make personnel
knowledgeable of marine mammals, protected species, and visual cues
related to the presence of marine mammals and protected species.
(2) Weekly and Post-Exercise Monitoring: The Marine Corps would
conduct post-exercise monitoring the morning following an exercise,
unless an exercise occurs on a Friday, in which case the post-exercise
sweep would take place the following Monday. Weekly monitoring events
would include a maximum of five pre-exercise and four post-exercise
sweeps. The maximum number of days that would elapse between pre- and
post-exercise monitoring events would be approximately three days, and
would normally occur on weekends. If marine mammals are observed during
this monitoring, sighting data identical to those collected by PEDRO
crew would be recorded.
(3) Long-Term Monitoring: The Marine Corps has awarded Duke
University Marine Lab (Duke) a contract to obtain abundance, group
dynamics (e.g., group size, age census), behavior, habitat use, and
acoustic data on the bottlenose dolphins which inhabit Pamlico Sound,
specifically those around BT-9 and BT-11. Duke began conducting boat-
based surveys and passive acoustic monitoring of bottlenose dolphins in
Pamlico Sound in 2000 (Read et al., 2003) and specifically at BT-9 and
BT-11 in 2003 (Mayer, 2003). To date, boat-based surveys indicate that
bottlenose dolphins may be resident to Pamlico Sound and use BT
restricted areas on a frequent basis. Passive acoustic monitoring (PAM)
provides more detailed insight into how dolphins use the two ranges, by
monitoring for their vocalizations year-round, regardless of weather
conditions or darkness. In addition to these surveys, Duke scientists
are testing a real-time passive acoustic monitoring system at BT-9 that
will allow automated detection of bottlenose dolphin whistles,
providing yet another method of detecting dolphins prior to training
operations. Although it is unlikely this PAM system would be active for
purposes of implementing mitigation measures before an exercise prior
to expiration of the proposed Authorization, it could be operational
for future MMPA incidental take authorizations and would be evaluated
for effectiveness at the appropriate time.
(4) Reporting: The Marine Corps will submit a report to us within
90 days after expiration of the Authorization or, if a subsequent
incidental take authorization is requested, within 120 days prior to
expiration of the Authorization. The report will summarize the type and
amount of training exercises conducted, all marine mammal observations
made during monitoring, and if mitigation measures were implemented.
The report will also address the effectiveness of the monitoring plan
in detecting marine mammals.
General Notification of Injured or Dead Marine Mammals
The Marine Corps will systematically observe training operations
for injured or disabled marine mammals. In addition, the Marine Corps
would monitor the principal marine mammal stranding networks and other
media to correlate analysis of any dolphin strandings that could
potentially be associated with Cherry Point training operations.
Marine Corps personnel will ensure that we are notified immediately
or as soon as clearance procedures allow if an injured, stranded, or
dead marine mammal is found during or shortly after, and in the
vicinity of, any training operations. The Marine Corps will provide us
with species or description of the animal(s), the condition of the
animal(s) (including carcass condition if the animal is dead),
location, time of first discovery, observed behaviors (if alive), and
photo or video (if available).
In the event that an injured, stranded, or dead marine mammal is
found by Marine Corps personnel that is not in the vicinity of, or
found during or shortly after operations, the Marine Corps personnel
will report the same information as listed above as soon as
operationally feasible and clearance procedures allow.
General Notification of a Ship Strike
In the event of a vessel strike, at any time or place, the Marine
Corps shall do the following:
Immediately report to us the species identification (if
known), location (lat/long) of the animal (or the strike if the animal
has disappeared), and whether the animal is alive or dead (or unknown);
Report to us as soon as operationally feasible the size
and length of the animal, an estimate of the injury status (e.g., dead,
injured but alive, injured and moving, unknown, etc.), vessel class/
type and operational status;
Report to us the vessel length, speed, and heading as soon
as feasible; and
Provide us a photo or video, if equipment is available.
Estimated Take by Incidental Harassment
The following provides the Marine Corps' model for take of dolphins
from explosives (without consideration of mitigation and the
conservative assumption that all explosives would land in the water and
not on the targets or land) and potential for direct hits and our
analysis of potential harassment from small vessel and aircraft
operations.
The method to estimate the number of marine mammals potentially
taken by the specified activities is based on bottlenose dolphin
density, the amount and type of ordnance proposed, and distances to our
harassment threshold criteria. We refer the reader to the notice for
the proposed Authorization (78 FR 19224, Friday, March 29, 2013) for a
[[Page 42048]]

Take From Explosives
The Marine Corps conservatively modeled that all explosives would
detonate at a 1.2 m (3.9 ft) water depth despite the training goal of
hitting the target, resulting in an above water or on land explosion.
For sources that are detonated at shallow depths, it is frequently the
case that the explosion may breech the surface with some of the
acoustic energy escaping the water column. The source levels presented
in the table above have not been adjusted for possible venting nor does
the subsequent analysis take this into account. Properties of explosive
sources used at BT-9, including net explosive weight (NEW), peak one-
third-octave (OTO) source level, the approximate frequency at which the
peak occurs, and rounds per burst are described in Table 9. Refer to
Table 10 for distances to our harassment threshold levels from these
sources.

----------------------------------------------------------------------------------------------------------------
In order to calculate take, the Marine Corps considered the
distances to which animals could be harassed along with dolphin
density. They used the density estimate from Read et al. (2003) to
calculate take from munitions firing (0.183/square kilometer (km\2\))
and based take calculations for munitions firing on 100 percent water
detonation. Because the goal of training is to hit the targets and not
the water, we consider these take estimates based on 100 percent water
detonation of munitions to be conservative.
Based on dolphin density and amount of munitions expended, there is
very low potential for Level A harassment, serious injury, and
mortality and monitoring and mitigation measures are anticipated to
further negate this potential. Accordingly, we are not proposing to
issue these levels of take. In total, from firing of explosive
ordnances, the Marine Corps has requested, and we propose to issue, the
incidental take of 25 bottlenose
[[Page 42049]]
dolphins from Level B harassment (Table 6).

Take From Direct Hit
As described in the notice for the proposed Authorization (78 FR
19224, Friday, March 29, 2013), we estimate that the potential risk of
a direct hit to an animal in the target area is discountable. The
probability of hitting a bottlenose dolphin at the BTs can be derived
as follows: Probability = dolphin's dorsal surface area times the
density of dolphins. The estimated dorsal surface area of a bottlenose
dolphin is 1.425 m\2\ (or the average length of 2.85 m times the
average body width of 0.5 m). Thus, using Read et al. (2003)'s density
estimate of 0.183 dolphins/km\2\, without consideration of mitigation
and monitoring implementation, the probability of a dolphin being hit
within BT-9 is 2.61 x 10-\7\ and within BT-11 is 9.4 x
10-\8\. Using the proposed levels of ordnance expenditures
at each in-water BT (78 FR 19224, Friday, March 29, 2013) and taking
into account that only 36 percent of the ordnance deployed at BT-11 is
over water, as described in the application, the estimated potential
number of ordnance strikes on a marine mammal per year is 0.263 at BT-9
and 0.034 at BT-11. It would take approximately three years of ordnance
deployment at the BTs before it would be likely or probable that one
bottlenose dolphin would be struck by deployed inert ordnance. Again,
these estimates are without consideration to proposed monitoring and
mitigation measures.
The Marine Corps proposed three methods of exercise monitoring
(i.e., PEDRO, cold pass, and range cameras). When considering the
implementation of the mitigation and monitoring measures, the chance of
a marine mammal being taken by direct hit is discountable.
Take From Vessel and Aircraft Presence
Interactions with vessels are not a new experience for bottlenose
dolphins in Pamlico Sound. Pamlico Sound is heavily used by
recreational, commercial (fishing, daily ferry service, tugs, etc.),
and military (including the Navy, Air Force, and Coast Guard) vessels
year-round. The NMFS' Southeast Regional Office has developed marine
mammal viewing guidelines to educate the public on how to responsibly
view marine mammals in the wild and avoid causing a take (https://www.nmfs.noaa.gov/pr/education/southeast). The guidelines recommend
that vessels should remain a minimum of 50 yards from a dolphin,
operate vessels in a predictable manner, avoid excessive speed or
sudden changes in speed or direction in the vicinity of animals, and
not to pursue, chase, or separate a group of animals. The Marine Corps
would abide by these guidelines to the fullest extent practicable. The
Marine Corps would not engage in high speed exercises should a marine
mammal be detected within the immediate area of the BTs prior to
training commencement and would never closely approach, chase, or
pursue dolphins. Detection of marine mammals would be facilitated by
personnel monitoring on the vessels and those marking success rate of
target hits and monitoring of remote camera on the BTs (see Monitoring
and Reporting section).
Based on the description of the action, the other activities
regularly occurring in the area, the species that may be exposed to the
activity and their observed behaviors in the presence of vessel
traffic, and the implementation of measures to avoid vessel strikes, we
determined that it is unlikely that the operation of vessels during
surface-to-surface maneuvers will result in the take of any marine
mammals, in the form of either behavioral harassment, injury, serious
injury, or mortality.
Aircraft would move swiftly through the area and would typically
fly approximately 914 m (2,998.7 ft) from the water's surface before
dropping unguided munitions and above 4,572 m (2.8 miles) for
precision-guided munitions bombing. While the aircraft may approach as
low as 152 m (500 ft) to drop a bomb this is not the norm and would
never been done around marine mammals. Regional whale watching
guidelines advise aircraft to maintain a minimum altitude of 300 m
(1,000 ft) above all marine mammals, including small odontocetes, and
to not circle or hover over the animals to avoid harassment. Our
approach regulations limit aircraft from flying below 300 m (1,000 ft)
over a humpback whale (Megaptera novaeangliae) in Hawaii, a known
calving ground, and limit aircraft from flying over North Atlantic
right whales closer than 460 m (1,509 ft). Given that Marine Corps
aircraft would not fly below 300 m (984 ft) on the approach, would not
engage in hovering or circling the animals, and would not drop to the
minimal altitude of 152 m (500 ft) if a marine mammal is in the area,
we believe it unlikely that the operation of aircraft, as described
above, will result in take of bottlenose dolphins in Pamlico Sound in
any manner.
Negligible Impact Analysis and Determination
Pursuant to our regulations implementing the MMPA, an applicant is
required to estimate the number of animals that will be ``taken'' by
the specified activities (i.e., takes by harassment only, or takes by
harassment, injury, and/or death). This estimate informs the analysis
that we must perform to determine whether the activity will have a
``negligible impact'' on the species or stock. We have 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.'' A negligible
impact finding is based on the lack of likely adverse effects on annual
rates of recruitment or survival (i.e., population-level effects). An
estimate of the number and manner of takes, alone, is not enough
information
[[Page 42050]]
on which to base a negligible impact determination. We must also
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.), or any of
the other variables mentioned in the first paragraph (if known), as
well as the number and nature of estimated Level A takes, the number of
estimated mortalities, and effects on habitat.
The Marine Corps has conducted gunnery and bombing training
exercises at BT-9 and BT-11 for several years and, to date, the
monitoring reports indicate that no dolphin injury, serious injury, or
mortality has been attributed to these military training exercises. The
Marine Corps has a history of notifying the NMFS stranding network when
any injured or stranded animal comes ashore or is spotted by personnel
on the water. Therefore, stranded animals have been examined by
stranding responders, further confirming that it is unlikely training
contributes to marine mammal injuries or deaths. Due to the
implementation of the aforementioned proposed mitigation measures, no
take by Level A harassment or serious injury or mortality is
anticipated nor would any be authorized in the IHA. We are proposing,
however, to authorize 25 Level B harassment takes associated with
training exercises.
The Marine Corps has proposed a 1,000 yard (914 m) safety zone
around BT-9 despite the fact that the distance to our explosive Level B
harassment threshold is 228 yards (209 m). They also would consider an
area fouled if any dolphins are spotted within Raritan Bay (where BT-11
is located)--triggering a shutdown of activities in that area. The
Level B harassment takes allowed for in the Authorization would be of
very low intensity and would likely result in dolphins being
temporarily behaviorally affected by bombing or gunnery exercises. In
addition, takes may be attributed to animals not using the area when
exercises are occurring; however, this is difficult to calculate.
Instead, we look if the specified activities occur during and within
habitat important to vital life functions to better inform its
negligible impact determination.
Read et al. (2003) concluded that dolphins rarely occur in open
waters in the middle of North Carolina sounds and large estuaries, but
instead are concentrated in shallow water habitats along shorelines.
However, no specific areas have been identified as vital reproduction
or foraging habitat. Scientific boat based surveys conducted throughout
Pamlico Sound conclude that dolphins use the areas around the BTs more
frequently than other portions of Pamlico Sound (Maher, 2003) despite
the Marine Corps actively training in a manner identical to the
specified activities described here for years.
As described in the Affected Species section of this notice,
bottlenose dolphin stock segregation is complex with stocks overlapping
throughout the coastal and estuarine waters of North Carolina. It is
not possible for the Marine Corps to determine to which stock any
individual dolphin taken during training activities belong as this can
only be accomplished through genetic testing. However, it is likely
that many of the dolphins encountered would belong to the Northern or
Southern North Carolina Estuarine System stocks. These stocks have
abundance estimates of 950 and 2,454, respectively. We authorize 25
takes of bottlenose dolphins in total; therefore, this number
represents 2.6 and 1.0 percent, respectively, of those populations.
This species is not listed as threatened or endangered under the ESA.
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, we find that the specified USMC Air Station Cherry Point BT-9
and BT-11 training activities would result in the incidental take of
marine mammals, by Level B harassment only, and that the total taking
from would have a negligible impact on the affected species or stocks.
Subsistence Harvest of Marine Mammals
Marine mammals are not taken for subsistence uses within Pamlico
Sound; therefore, issuance of an IHA to the USMC for MCAS Cherry Point
training exercises would not have an unmitigable adverse impact on the
availability of the affected species or stocks for subsistence use.
Endangered Species Act (ESA)
No ESA-listed marine mammals are known to occur within the action
area. Therefore, there is no requirement for us to consult under
Section 7 of the ESA on the issuance of an Authorization under section
101(a)(5)(D) of the MMPA. However, ESA-listed sea turtles may be
present within the action area.
On September 27, 2002, NMFS issued a Biological Opinion (BiOp) on
Ongoing Ordnance Delivery at Bombing Target 9 (BT-9) and Bombing Target
11 (BT-11) at Marine Corps Air Station, Cherry Point, North Carolina.
The BiOp, which is still in effect, concluded that that the USMC's
proposed action will not result in adverse impacts to any ESA-listed
marine mammals and is not likely to jeopardize the continued existence
of the endangered green turtle (Chelonia mydas), leatherback turtle
(Dermochelys coriacea), Kemp's ridley turtle (Lepidochelys kempii), or
threatened loggerhead turtle (Caretta caretta). The Authorization will
not result in effects beyond those considered in the 2002 BiOp and we
do not anticipate the need for further Section 7 consultation for the
Authorization or the underlying activities proposed by the Marine
Corps. No critical habitat has been designated for these species in the
action area; therefore, none will be affected.
National Environmental Policy Act (NEPA)
On February 11, 2009, the Marine Corps issued a Finding of No
Significant Impact for its Environmental Assessment (EA) on MCAS Cherry
Point Range Operations. Based on the analysis of the EA, the Marine
Corps determined that the proposed action will not have a significant
impact on the human environment. We adopted the Marine Corps' EA and
signed a Finding of No Significant Impact on August 31, 2010. We have
again reviewed the proposed application and public comments and
determined that there are no substantial changes to the proposed action
or new environmental impacts or concerns. Therefore, we have determined
that a new or supplemental EA or Environmental Impact Statement is
unnecessary. The EA referenced above is available for review at https://www.nmfs.noaa.gov/pr/permits/incidental.htm.
Authorization
We have issued an Incidental Harassment Authorization to the Marine
Corps for the take of marine mammals incidental to various training
exercises at Marine Corps Air Station (MCAS) Cherry Point Range
Complex, North Carolina, July 1, 2013 through June 30, 2014, provided
the previously mentioned mitigation, monitoring, and reporting
requirements are incorporated.
