V. Paperwork Reduction Act
The rule does not contain any
information collection requirements that
require the approval of the Office of
Management and Budget under the
Paperwork Reduction Act (44 U.S.C.
chapter 35).
VI. Determination to Issue an Interim
Rule
A determination has been made under
the authority of the Secretary of Defense
that urgent and compelling reasons exist
to promulgate this interim rule without
prior opportunity for public comment.
DoD administers FMS programs to
maintain and strengthen relationships
with partner nations. Failure to nurture
these relationships may create a threat
to national security. This action is
necessary because of the recent and
foreseeable trend of increasing numbers
and complexity of indirect offsets
desired by DoD’s Foreign Military Sales
(FMS) customers.
Currently, Defense Federal
Acquisition Regulation Supplement
(DFARS) 225.7303–2(a)(3)(ii) provides
that the U.S. Government assumes no
obligation to satisfy or administer the
offset requirement or to bear any of the
associated costs. However, DFARS
225.7301(b) provides that the U.S.
Government conduct FMS acquisitions
under the same acquisition and contract
management procedures used for other
defense acquisitions. This requires the
contracting officer to adhere to FAR
provisions concerning the negotiation of
contracts and subcontracts (FAR part
15) and contract cost principles (FAR
part 31), and thus be capable of attesting
to the price reasonableness of FMS
contracts, including indirect offset costs
that are not tied directly to the end item.
Contracting officers must follow these
regulations even though no DoD
appropriated funds are being used to
pay for the effort, and DoD contracting
officers have no insight to pricing of the
indirect offset. In the past several years,
compliance with regulations has
resulted in an inability of contracting
officers to finalize FMS contract
negotiations.
The interim rule affirms that all offset
costs that involve benefits provided by
a U.S. defense contractor to an FMS
customer that are unrelated to the item
being purchased under a Letter of Offer
and Acceptance (LOA), i.e., indirect
offset costs, are deemed reasonable for
purposes of FAR part 31. The rule
provides that no additional analysis is
necessary on the part of the contracting
officer, provided that the U.S. defense
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
contractor submits to the contracting
officer a signed offset agreement or other
documentation showing that the FMS
customer has made the provision of an
indirect offset of a certain dollar value
a condition of the FMS acquisition.
Finally, the rule provides that the FMS
customer shall be notified through the
LOA that indirect offset costs are
deemed reasonable without any further
analysis by the contracting officer.
It is essential that DoD implement this
interim rule immediately to clarify that
contracting officers are not required to
make price reasonableness
determinations on costs associated with
indirect offsets under FMS agreements,
which, while included in the FMS
contract, fall outside of the DoD
contracting officer’s purview. Immediate
implementation will allow DoD
contracting officers to finalize pending
negotiations for FMS contracts to
support U.S. allies and partners, and
maintain bilateral relationships.
However, pursuant to 41 U.S.C. 1707
and FAR 1.501–3(b), DoD will consider
public comments received in response
to this interim rule in the formation of
the final rule.

Background
Sections 101(a)(5)(A) and (D) of the
MMPA (16 U.S.C. 1361 et se.) direct the
Secretary of Commerce to allow, upon
request, the incidental, but not
intentional, taking of small numbers of
marine mammals by U.S. citizens who
engage in a specified activity (other than
commercial fishing) within a specified
geographical region if certain findings
are made and either regulations are
issued or, if the taking is limited to
harassment, a notice of a proposed
authorization is provided to the public
for review.
Authorization for incidental takings
shall be granted if NMFS finds that the
taking will have a negligible impact on
the species or stock(s), will not have an
unmitigable adverse impact on the
availability of the species or stock(s) for
subsistence uses (where relevant), and if
the permissible methods of taking and
requirements pertaining to the
mitigation, monitoring, and reporting of
such takings are set forth. NMFS has
defined ‘‘negligible impact’’ in 50 CFR
216.103 as ‘‘an impact resulting from
the specified activity that cannot be
reasonably expected to, and is not
reasonably likely to, adversely affect the
species or stock through effects on
annual rates of recruitment or survival.’’
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’’ limitations indicated above and
amended the definition of ‘‘harassment’’
as applied to ‘‘military readiness

activity’’ to mean: ‘‘(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].’’ (Section 3(18)(B) of the
MMPA.)
Summary of Request
On August 20, 2014, NMFS received
an application from the Navy requesting
a letter of authorization (LOA) for the
take of bottlenose and Atlantic spotted
dolphins incidental to the Navy’s JLOTS
training activities in nearshore waters at
the Joint Expeditionary Base (JEB) Little
Creek-Fort Story in Virginia and at
Camp Lejeune in North Carolina. The
Navy is requesting regulations that
would allow NMFS to authorize take,
via a 5-year LOA, of marine mammals
incidental to training activities. These
activities are classified as military
readiness activities. The Navy states that
these activities may result in take of
marine mammals from noise from
temporary pier construction associated
with the JLOTS training activities. The
Navy requests to take bottlenose and
Atlantic spotted dolphins by Level B
harassment.
Specified Activity
A detailed description of the Navy’s
proposed JLOTS activities is provided
in the proposed rule (80 FR 2636;
January 20, 2015) and is not repeated
here. No changes were made to the
proposed action since the proposed rule
was published.
Comments and Responses
On January 20, 2015 (80 FR 2636),
NMFS published a proposed rule to
authorize the taking of marine mammals
incidental to the Navy’s JLOTS training
activities. During the 30-day public
comment period, NMFS received
comments from the Marine Mammal
Commission (Commission) and a private
citizen. Comments specific to section
101(a)(5)(A) of the MMPA and NMFS’
analysis of impacts to marine mammals
are summarized and addressed below
and/or throughout the final rule.
Comment 1: The Commission
recommends that NMFS require the
Navy to submit a proposed monitoring
plan in support of JLOTS training
activities, which at the very least should
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
31311
include a brief synopsis of the projects
the Navy plans to conduct, for public
review and comment prior to issuance
of the final regulations.
Response 1: The Navy will use the
existing Integrated Comprehensive
Monitoring Program and the studybased approach that Navy and NMFS
agreed to during a prior adaptive
management session to satisfy
monitoring requirements for the JLOTS
MMPA authorization. The Navy’s LOA
application provided details on the
Integrated Comprehensive Monitoring
Plan, as well as the Web site where the
public can obtain further information on
all of the Navy’s marine species
monitoring work (https://
www.nmfs.noaa.gov/pr/permits/
incidental.htm#applications).
To ensure efficient implementation of
the Navy’s monitoring program and
maintain consistency with how the
program is already being implemented
for the Atlantic Fleet Training and
Testing (AFTT) MMPA authorization,
the same AFTT adaptive management
process and reporting deadlines will be
used for the JLOTS authorization. In
fact, the in-water pile driving associated
with JLOTS was originally part of the
AFTT Environmental Impact Statement
(EIS) and LOA, and this pile-driving
activity and its associated monitoring
requirements already went through
public review and comment during the
AFTT EIS and MMPA process, as JLOTS
activities were not removed until the
Final Rule and Final EIS stage.
Table 1 shows Navy projects that help
achieve the Integrated Comprehensive
Monitoring Program’s top level goals.
There may be future unforeseen budget
or other logistical issues that require
modification to study design, scope, or
direction of one or more of these
projects. However, the Navy has
currently either planned for or is
currently undertaking these projects as
described. The first two projects will
investigate the sound source level of
pile driving and its effects on marine
species and the remaining four projects
help advance scientific knowledge of
presence, density, distribution, and
movement of marine species found in
the Chesapeake Bay and along the coasts
of Virginia and North Carolina.
Information on these projects
and all Navy monitoring projects
can be found at https://
www.navymarinespeciesmonitoring.us/.
Therefore, NMFS does not believe
that an additional monitoring plan in
support of JLOTS training activities or
additional comment period is
warranted.

Their behavioral responses are evaluated at various received levels and durations of pre-recorded
vibratory pile driving noise playback.
2013–14: MMP developed experimental design and performed
experimental trials with five dolphins.
2014–2015: MMP conducting trials
and analyzing dolphin responses.
Measure the sound produced by both vibratory and
impact pile driving methods on various types of
piles at Navy installations along the U.S. East
Coast. This data will support sound source measurement and propagation modelling for assessing
the impacts of pile driving.
Field work 2013–2015.
Reports available for measurements at JEB Little Creek, NS
Norfolk, and Philadelphia Naval
Shipyard.
Additional measurements to be
completed at NS Mayport and

Comment 2: A private citizen wrote
against NMFS issuing the LOA to the
Navy because of concerns that marine
mammals will be killed.
Response 2: As described in detail in
the proposed rule (80 FR 2636; January
20, 2015), the Navy’s proposed JLOTS
training activities would only result in
Level B behavioral harassment of
bottlenose and Atlantic spotted
dolphins. No injury or mortality is
expected, and none is authorized.
Description of Marine Mammals in the
Area of the Specified Activities
There are six marine mammal species
under NMFS jurisdiction with possible
or known occurrence in the Navy’s
JLOTS training area at the JEB Little
Creek-Fort Story in Virginia and at
Camp Lejeune in North Carolina, as
indicated in Table 2. Four marine
mammal species are listed under the

NMFS has reviewed the information
compiled by the Navy on the
abundance, status, and distribution of
marine mammal species in the waters of
the JLOTS training areas of the North
Atlantic coast, which was derived from
peer reviewed literature, the Navy
Marine Resource Assessments, and
NMFS Stock Assessment Reports.
NMFS considers this information to be
the best available. This information may
be viewed in the Navy’s LOA
application and the Navy’s EA (see
Availability). Additional information is
available in the NMFS Stock
Assessment Reports, which may be
viewed at: https://www.nmfs.noaa.gov/
pr/sars/species.htm.
Fin whales, North Atlantic right
whale, humpback whale, and sei whale
are considered rare in the JLOTS
training areas. These mysticete whales
VerDate Sep<11>2014

tend to be distributed in offshore areas.
Occurrences of these species in the
inshore waters off JEB Little Creek-Fort
Story or near shore waters off Camp
Lejeune are expected to be rare. Due to
their extremely rare occurrence within
the training areas where pile driving
and removal occur, the Navy and NMFS
do not anticipate any take of fin, North
Atlantic right, humpback, or sei whales.
Therefore, these species are not
addressed further in this document.
Potential Effects of the Specified
Activity on Marine Mammals
When considering the effects of
various kinds of sound on the marine
environment, it is necessary to
understand that different kinds of
marine life are sensitive to different
frequencies of sound. Based on available
behavioral data, audiograms have been
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
derived using auditory evoked
potentials, anatomical modeling, and
other data. From this, Southall et al.
(2007) designated ‘‘functional hearing
groups’’ for marine mammals and
estimate the lower and upper
frequencies of functional hearing of the
groups. The functional groups and the
associated frequencies are indicated
below. It should be noted that animals
are less sensitive to sounds at the outer
edge of their functional range and most
sensitive to sounds of frequencies
towards the middle of their functional
hearing range:
• Low frequency cetaceans (13
species of mysticetes): Functional
hearing is estimated to occur between
approximately 7 Hz and 30 kHz;
• Mid-frequency cetaceans (32
species of dolphins, six species of larger
toothed whales, and 19 species of
E:\FR\FM\02JNR1.SGM

beaked and bottlenose whales):
Functional hearing is estimated to occur
between approximately 150 Hz and 160
kHz;
• High frequency cetaceans (eight
species of true porpoises, six species of
river dolphins, Kogia, the franciscana,
and four species of cephalorhynchids):
Functional hearing is estimated to occur
between approximately 200 Hz and 180
kHz;
• Phocid pinnipeds in Water:
Functional hearing is estimated to occur
between approximately 75 Hz and 100
kHz; and
• Otariid pinnipeds in Water:
Functional hearing is estimated to occur
between approximately 100 Hz and 40
kHz.
As mentioned previously in this
document, only bottlenose dolphin and
Atlantic spotted dolphin are likely to
occur in the JLOTS training areas. Both
of these two species are classified as
mid-frequency cetaceans (Southall et al.
2007). Because their hearing frequency
range overlaps with the frequencies
associated with pile driving, the Navy
and NMFS determined that in-water
pile removal and pile driving during the
JLOTS training activities have the
potential to result in behavioral
harassment.
Marine mammals exposed to highintensity sound repeatedly or for
prolonged periods can experience
hearing threshold shift (TS), which is
the reduction of hearing sensitivity in
the frequency ranges of the sound
source (Kastak et al. 1999; Schlundt et
al. 2000; Finneran et al. 2002; 2005). TS
can be permanent (PTS), in which case
the reduction of hearing sensitivity is
unrecoverable, or temporary (TTS), in
which case the animal’s reduction of
hearing sensitivity will recover over
time (Southall et al. 2007). Since marine
mammals depend on acoustic cues for
vital biological functions, such as
orientation, communication, finding
prey, and avoiding predators, hearing
impairment could result in the reduced
ability of marine mammals to detect or
interpret important sounds. Repeated
noise exposure that causes TTS could
lead to PTS.
Experiments on a bottlenose dolphin
(Tursiops truncatus) and beluga whale
(Delphinapterus leucas) showed that
exposure to a single watergun impulse
at a received level of 207 kPa (or 30 psi)
peak-to-peak (p-p), which is equivalent
to 228 dB (p-p) re 1 mPa, resulted in a
7 and 6 dB TTS in the beluga whale at
0.4 and 30 kHz, respectively.
Thresholds returned to within 2 dB of
the pre-exposure level within 4 minutes
of the exposure (Finneran et al. 2002).
No TTS was observed in the bottlenose
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
dolphin. Although the source level of
one hammer strike for pile driving is
expected to be much lower than the
single watergun impulse cited here,
animals being exposed for a prolonged
period to repeated hammer strikes could
receive more noise exposure in terms of
sound exposure level (SEL) than from
the single watergun impulse (estimated
at 188 dB re 1 mPa2-s) in the
aforementioned experiment (Finneran et
al. 2002).
Chronic exposure to excessive, though
not high-intensity, noise could cause
masking at particular frequencies for
marine mammals that utilize sound for
vital biological functions (Clark et al.
2009). Masking is the obscuring of
sounds of interest by other sounds, often
at similar frequencies. Masking
generally occurs when sounds in the
environment are louder than, and of a
similar frequency as, auditory signals an
animal is trying to receive. Masking can
interfere with detection of acoustic
signals, such as communication calls,
echolocation sounds, and
environmental sounds important to
marine mammals. Therefore, under
certain circumstances, marine mammals
whose acoustical sensors or
environment are being severely masked
could also be impaired.
Masking occurs at the frequency band
which the animals utilize. Since noise
generated from in-water pile removal
and driving is mostly concentrated at
low frequency ranges, it may have little
effect on high-frequency echolocation
sounds by odontocetes (toothed whales).
However, the lower frequency manmade noises are more likely to affect the
detection of communication calls and
other potentially important natural
sounds, such as surf and prey noise. The
noises may also affect communication
signals when those signals occur near
the noise band, and thus reduce the
communication space of animals (e.g.,
Clark et al. 2009), cause modification in
vocalization patterns (e.g., Foote et al.
2004; Holt et al. 2009), and cause
increased stress levels (Rolland et al.
2012).
Masking can potentially impact the
species at community, population, or
even ecosystem levels, as well as
individual levels. Masking affects both
senders and receivers of the signals and
could have long-term chronic effects on
marine mammal species and
populations. Recent science suggests
that low frequency ambient sound levels
in the world’s oceans have increased by
as much as 20 dB (more than 3 times,
in terms of SPL) from pre-industrial
periods, and most of these increases are
from distant shipping (Hildebrand
2009). All anthropogenic noise sources,
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
such as those from vessel traffic and pile
removal and driving, contribute to the
elevated ambient noise levels, thus
intensifying masking.
The sum of noise from the Navy’s
JLOTS training activities is confined to
a limited area and is temporary and
intermittent; therefore, the noise
generated is not expected to contribute
to increased ocean ambient noise. In
addition, due to shallow water depths in
the training area, underwater sound
propagation of low-frequency sound
(which is the major noise source from
pile driving) is expected to be poor.
Finally, in addition to TS and
masking, exposure of marine mammals
to certain sounds could lead to
behavioral disturbance (Richardson et
al. 1995), such as: Changing durations of
surfacing and dives, number of blows
per surfacing, or moving direction and/
or speed; reduced/increased vocal
activities; changing/cessation of certain
behavioral activities, such as socializing
or feeding; visible startle response or
aggressive behavior, such as tail/fluke
slapping or jaw clapping; and avoidance
of areas where noise sources are located.
The biological significance of many of
these behavioral disturbances is difficult
to predict, especially if the detected
disturbances appear minor. However,
the consequences of behavioral
modification could be expected to be
biologically significant at the population
level if the change affects growth,
survival, or reproduction. Some of these
types of significant behavioral
modifications include:
• Drastic change in diving/surfacing
patterns (such as those thought to be
causing beaked whale strandings due to
exposure to military mid-frequency
tactical sonar);
• Extended habitat abandonment due
to loss of desirable acoustic
environment; and
• Extended cessation of feeding or
social interaction.
The onset of behavioral disturbance
from anthropogenic noise depends on
both external factors (characteristics of
noise sources and their paths) and the
receiving animals (hearing, motivation,
experience, demography), and is
therefore difficult to predict (Southall et
al. 2007). In order to give rise to
significant/population level effects we
would expect that exposures would
have to be prolonged and over a large
area.
Anticipated Effects on Marine Mammal
Habitat
No permanent impacts to marine
mammal habitat are anticipated to occur
as a result of the training activities. The
Navy’s JLOTS training activities would
E:\FR\FM\02JNR1.SGM
02JNR1
Federal Register / Vol. 80, No. 105 / Tuesday, June 2, 2015 / Rules and Regulations
not modify the existing habitat.
Therefore, no restoration of the habitat
would be necessary. A temporary,
small-scale loss of foraging habitat may
occur for marine mammals, if the
marine mammals leave the area during
pile extraction and driving activities.
Acoustic energy created during pile
driving and removal work would have
the potential to disturb fish within the
vicinity of the training areas. As a result,
the affected areas could temporarily lose
foraging value to marine mammals.
During pile driving, high noise levels
may exclude fish from the vicinity of
the pile driving. Hastings and Popper
(2005) identified several studies that
suggest fish will relocate to avoid areas
of damaging noise energy. If fish leave
the area of disturbance, the affected area
may have a temporarily decreased
foraging value during impact
hammering and vibratory removal of
piles.
The duration of fish avoidance of this
area after pile driving stops is unknown.
However, the affected area represents an
extremely small portion of the total
foraging range of marine mammals that
may be present in and around the
project area.
Because of the short duration of the
activities and the relatively small area of
the habitat that may be affected, the
impacts to marine mammals and the
food sources that they utilize are not
expected to cause significant or longterm consequences for individual
marine mammals or marine mammal
populations.

Mitigation
In order to issue an incidental take
authorization (ITA) under section
101(a)(5)(A) of the MMPA, NMFS must
set forth the ‘‘permissible methods of
taking pursuant to such activity, and
other means of effecting the least
practicable adverse impact on such
species or stock and its habitat, paying
particular attention to rookeries, mating
grounds, and areas of similar
significance.’’
The NDAA of 2004 amended the
MMPA as it relates to military readiness
activities 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 JLOTS LOA

readiness activities. Details of the
mitigation measures are provided

Impact Pile Driving Ramp-Up
Soft starts are performed during
impact installation each day. During a
soft start, an initial set of strikes from
the impact hammer at reduced energy is
performed before the hammer is able to
be operated at full power and speed.
The energy reduction of an individual
hammer cannot be quantified because
they vary by individual driver. Also, the
number of strikes will vary at reduced
energy because raising the hammer at
less than full power and then releasing
it results in the hammer ‘‘bouncing’’ as
it strikes the pile resulting in multiple
‘‘strikes.’’ A benefit of a soft start is that
marine species in the vicinity are
provided a ‘‘warning,’’ giving them an
opportunity to leave the area at the first
occurrence of the noise, prior to full
capacity operation. This is expected to
reduce any potential exposures to
underwater noise levels that could
cause behavioral disturbance or injury.
Mitigation Zone and Shutdown Measure
The Navy will establish a mitigation
zone of 60 yards (55 m) around the pile
being driven. Visual observation will be
conducted starting 30 minutes prior to,
during, and until 30 minutes after the
exercise within the mitigation zone. The
exercise will not commence if
concentrations of floating vegetation
(Sargassum) are observed in the
mitigation zone.
Pile driving will cease if a marine
mammal is visually detected within the
mitigation zone. Pile driving may
re-commence if any one of the following
conditions is met: (1) The animal is
observed exiting the mitigation zone, (2)
the animal is thought to have exited the
mitigation zone based on its course and
speed, or (3) the mitigation zone has
been clear from any additional sightings
for a period of 30 minutes.
Marine Species Awareness Training
Consistent with current requirements,
all personnel standing watch on the
bridge, Commanding Officers, Executive
Officers, and Lookouts will successfully
complete the Marine Species Awareness
Training prior to standing watch or
serving as a Lookout. The training is
designed to improve the effectiveness of
visual observations for marine
resources, including marine mammals.
The training provides information on
sighting cues, visual observation tools
and techniques, and sighting
notification procedures.
Vessels
Vessels will avoid approaching
marine mammals head on and will
maneuver to maintain a mitigation zone

North Atlantic Right Whale MidAtlantic Migration Corridor
A North Atlantic right whale
migratory route is located off the midAtlantic coast of the United States.
When transiting within the following
areas from November 1 through April
30, which correspond to the portions of
the JLOTS study area where a vessel
speed limit applies to non-federal
vessels, the Navy will practice increased
vigilance, exercise extreme caution, and
proceed at the slowest speed that is
consistent with safety, mission, and
training objectives:
• Chesapeake Bay: Within a 20 nm
radius of the following (as measured
seaward from the COLREGS lines):

Mitigation Conclusions
NMFS has carefully evaluated the
applicant’s proposed mitigation
measures and considered a range of
other measures in the context of
ensuring that NMFS prescribes the
means of effecting the least practicable
adverse impact on the affected marine
mammal species and stocks and their
habitat. No additional mitigation
measures were recommended during the
public comment period on the rule. Our
evaluation of potential measures
included consideration of the following
factors in relation to one another:
• The manner in which, and the
degree to which, the successful
implementation of the measure is
expected to minimize adverse impacts
to marine mammals;
• The proven or likely efficacy of the
specific measure to minimize adverse
impacts as planned; and
• The practicability of the measure
for applicant implementation, including
consideration of personnel safety,
practicality of implementation, and

Federal Register / Vol. 80, No. 105 / Tuesday, June 2, 2015 / Rules and Regulations
impact on the effectiveness of the
military readiness activity.
Any mitigation measure(s) prescribed
by NMFS should be able to accomplish,
have a reasonable likelihood of
accomplishing (based on current
science), or contribute to the
accomplishment of one or more of the
general goals listed below:
1. Avoidance or minimization of
injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may
contribute to this goal).
2. A reduction in the numbers of
marine mammals (total number or
number at biologically important time
or location) exposed to received levels
of noise, or other activities expected to
result in the take of marine mammals
(this goal may contribute to 1, above, or
to reducing harassment takes only).
3. A reduction in the number of times
(total number or number at biologically
important time or location) individuals
would be exposed to received levels of
noise, or other activities expected to
result in the take of marine mammals
(this goal may contribute to 1, above, or
to reducing harassment takes only).
4. A reduction in the intensity of
exposures (either total number or
number at biologically important time
or location) to received levels of noise,
or other activities expected to result in
the take of marine mammals (this goal
may contribute to 1, above, or to
reducing the severity of harassment
takes only).
5. Avoidance or minimization of
adverse effects to marine mammal
habitat, paying special attention to the
food base, activities that block or limit
passage to or from biologically
important areas, permanent destruction
of habitat, or temporary destruction/
disturbance of habitat during a
biologically important time.
6. For monitoring directly related to
mitigation—an increase in the
probability of detecting marine
mammals, thus allowing for more
effective implementation of the
mitigation.
NMFS has determined that the
mitigation measures provide the means
of effecting the least practicable adverse
impact 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.
Monitoring and Reporting
In order to issue an ITA for an
activity, section 101(a)(5)(A) of the
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
MMPA states that NMFS must set forth
‘‘requirements pertaining to the
monitoring and reporting of such
taking.’’ The MMPA implementing
regulations at 50 CFR 216.104(a)(13)
indicate that requests for LOAs 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.
Monitoring measures prescribed by
NMFS should accomplish one or more
of the following general goals:
1. An increase in the probability of
detecting marine mammals, both within
the mitigation zone (thus allowing for
more effective implementation of the
mitigation) and in general to generate
more data to contribute to the analyses
mentioned below.
2. An increase in our understanding
of how many marine mammals are
likely to be exposed to levels of noise
that we associate with specific adverse
effects, such as behavioral harassment,
TTS, or PTS.
3. An increase in our understanding
of how marine mammals respond to
stimuli expected to result in take and
how anticipated adverse effects on
individuals (in different ways and to
varying degrees) may impact the
population, species, or stock
(specifically through effects on annual
rates of recruitment or survival) through
any of the following methods:
a. Behavioral observations in the
presence of stimuli compared to
observations in the absence of stimuli
(need to be able to accurately predict
received level, distance from source,
and other pertinent information).
b. Physiological measurements in the
presence of stimuli compared to
observations in the absence of stimuli
(need to be able to accurately predict
received level, distance from source,
and other pertinent information).
c. Distribution and/or abundance
comparisons in times or areas with
concentrated stimuli versus times or
areas without stimuli.
4. An increased knowledge of the
affected species.
5. An increase in our understanding
of the effectiveness of certain mitigation
and monitoring measures.
Monitoring Measures
(1) Standard Watch Personnel
Ships operated by or for the Navy
shall have personnel assigned to stand
watch at all times, day and night, when
moving through the water (underway).
Watch personnel shall undertake
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
extensive training in accordance with
the U.S. Navy Lookout Training
Handbook or civilian equivalent,
including on-the-job instruction and a
formal Personal Qualification Standard
program (or equivalent program for
supporting contractors or civilians), to
certify that they have demonstrated all
necessary skills (such as detection and
reporting of floating or partially
submerged objects). Watch personnel
are composed of officers, enlisted men
and women, and civilian equivalents.
Their duties may be performed in
conjunction with other job
responsibilities, such as navigating the
ship or supervising other personnel.
While on watch, personnel employ
visual search techniques, including the
use of binoculars, using a scanning
method in accordance with the U.S.
Navy Lookout Training Handbook or
civilian equivalent. After sunset and
prior to sunrise, watch personnel
employ night visual search techniques,
which could include the use of night
vision devices.
A primary duty of watch personnel is
to detect and report all objects and
disturbances sighted in the water that
may be indicative of a threat to the ship
and its crew, such as debris, a
periscope, surfaced submarine, or
surface disturbance. Per safety
requirements, watch personnel also
report any marine mammals sighted that
have the potential to be in the direct
path of the ship as a standard collision
avoidance procedure. Because watch
personnel are primarily posted for safety
of navigation, range clearance, and manoverboard precautions, they are not
normally posted while ships are moored
to a pier. When anchored or moored to
a buoy, a watch team is still maintained
but with fewer personnel than when
underway.
While underway, Navy ships greater
than 65 ft. (20 m) in length have at least
two watch personnel; Navy ships less
than 65 ft. (20 m) in length and
contractor ships have at least one watch
person. While underway, watch
personnel are alert at all times and have
access to binoculars. Due to limited
manning and space limitations, small
boats and some craft transferring cargo
from ship to shore do not have
dedicated watch personnel, and the boat
crew is responsible for maintaining the
safety of the boat.
All vessels use extreme caution and
proceed at a ‘‘safe speed’’ so they can
take proper and effective action to avoid
a collision with any sighted object or
disturbance and can be stopped within
a distance appropriate to the prevailing
circumstances and conditions.

(2) Lookouts
Lookouts perform similar duties to
standard watch personnel, and are also
responsible for satisfying mitigation
requirements. The Navy will have one
Lookout positioned on the platform
(which could include a small boat, the
elevated causeway, or the shore) that
will maximize the potential for sightings
during pile driving and pile removal.
The Lookout positioned on the
elevated causeway or the shore will be
dedicated solely to diligent observation
of the air and surface of the water. They
will have multiple observation
objectives, which include but are not
limited to detecting the presence of
biological resources and recreational or
fishing boats, observing the mitigation
zone, and monitoring for equipment and
personnel safety concerns. Due to small
boat manning and space restrictions, a
Lookout positioned on a small boat may
include a member of the boat crew, and
may be responsible for tasks in addition
to observing the air or surface of the
water (e.g., navigation of a rigid hull
inflatable boat). However, a boat
Lookout will, to the maximum extent
practicable and consistent with safety
and training requirements, comply with
the observation objectives described
above for a Lookout positioned on the
elevated causeway or the shore.
Lookouts will also perform visual
observation starting 30 minutes prior to,
during, and until 30 minutes after the
exercise within a mitigation zone of 60
yards (55 m) around the pile being
driven.
Integrated Comprehensive Monitoring
Program
The Navy will use the existing
Integrated Comprehensive Monitoring
Program (ICMP) and its new ‘‘studybased’’ approach to satisfy monitoring
requirements for the JLOTS MMPA
authorization. To ensure efficient
implementation of the program and
maintain consistency with how the
program is currently being implemented
for the Atlantic Fleet Training and
Testing (AFTT) MMPA authorization,
Navy will use the same AFTT adaptive
management process and reporting
deadlines for the JLOTS authorization.
The ICMP is intended to coordinate
monitoring efforts across all regions
where the Navy trains and tests and to
allocate the most appropriate level and
type of effort for each range complex
(U.S. Department of the Navy 2010).
Originally, the Navy monitoring
program was composed of a collection
of ‘‘range-specific’’ monitoring plans,
each developed individually as part of
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
Marine Mammal Protection Act and
Endangered Species Act compliance
processes as environmental
documentation was completed. These
individual plans established specific
monitoring requirements for each range
complex and were collectively intended
to address the ICMP top-level goals.
More information is provided in the
Federal Register notice for the propose
rule (80 FR 2636; January 20, 2015).
Past and Current Monitoring in the
Navy JLOTS Training Areas
NMFS has not previously issued
incidental take authorizations to the
Navy concerning its JLOTS training on
the Atlantic coast. Therefore, no past
and current monitoring is available.
Reporting
In order to issue an ITA for an
activity, section 101(a)(5)(A) of the
MMPA states that NMFS must set forth
‘‘requirements pertaining to the
monitoring and reporting of such
taking.’’ Effective reporting is critical
both to compliance as well as ensuring
that the most value is obtained from the
required monitoring. Reports from
individual monitoring events, results of
analyses, publications, and periodic
progress reports for specific monitoring
projects will be posted to the U.S. Navy
Marine Species Monitoring web portal
as they become available. For the Navy’s
JLOTS LOA, NMFS requires the
following reporting measures to be
implemented:
(1) General Notification of Injured or
Dead Marine Mammals
Navy personnel will ensure that
NMFS (regional stranding coordinator)
is notified immediately (or as soon as
clearance procedures allow) if an
injured or dead marine mammal is
found during or shortly after, and in the
vicinity of, any Navy training exercise.
The Navy will provide NMFS with
species identification 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 photographs or video (if
available).
(2) Annual Monitoring and Exercise
Report
As noted above, reports from
individual monitoring events, results of
analyses, publications, and periodic
progress reports for specific monitoring
projects would be posted to the Navy’s
Marine Species Monitoring web portal
as they become available. Progress and
PO 00000

results from all monitoring activity
conducted within the JLOTS training
area would be summarized in an annual
report. This report shall detail the
monitoring protocol, summarize the
data recorded during monitoring, and
estimate the number of marine
mammals that may have been harassed.
Draft reports should be combined
with the Navy’s Atlantic Fleet Training
and Testing exercise and monitoring
reports and submitted to NMFS for
review by February 13 (for exercises)
and April 1 (for monitoring) each year.
NMFS would review the report and
provide comments for incorporation
within 3 months.
Estimated Take of Marine Mammals
In the potential effects section, NMFS’
analysis identified a variety of impacts
that could potentially result from
exposure to noise during the Navy’s
JLOTS training activities. In this section,
we will relate the potential effects to
marine mammals from these sound
sources to the MMPA definitions of
Level A and Level B Harassment and
attempt to quantify the effects that
might occur from the specific training
activities that the Navy proposes in the
JLOTS training areas.
Definition of Harassment
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].
As discussed above, in-water pile
removal and pile driving (vibratory and
impact) generate loud noises that could
potentially harass marine mammals in
the vicinity of the Navy’s JLOTS
training activities.
Currently, NMFS uses 120 dB re 1
m Pa and 160 dB re 1 m Pa at the received
levels for the onset of Level B
harassment from non-impulse (vibratory
pile driving and removal) and impulse
sources (impact pile driving)
underwater, respectively. Table 3
summarizes the current NMFS marine
mammal take criteria.

Methods for Estimating Takes
The methods for estimating the
number and types of exposure are
described in the sections below,
followed by the method for quantifying
exposures of marine mammals to
sources of energy exceeding those
threshold values. Exposure of each was
determined by:
• The potential of each species to be
impacted by the acoustic sources as
determined by acoustic criteria for
marine mammals.
• The potential presence of each
species and their estimated density
inside the range to effect.
• The range to effect for impact
installation and vibratory extraction
(estimated by taking into account the
source levels, propagation loss, and
thresholds at which each acoustic
criterion is met).
Potential exposures were calculated
by multiplying the density of each
marine mammal species potentially
present by the total impacted area for
each threshold value, rounding the
result to the closest integer, and then
multiplying that result by the potential
number of days of pile driving.
Underwater Sound From Pile Driving
Sound levels produced by pile driving
are greatly influenced by factors
including pile type, driving method,
and the physical environment in which
the activity takes place. A number of
studies have examined sound pressure
levels recorded from underwater pile
driving projects in California and
Washington, creating a large body of
data for impact driving of steel pipe
piles.
To determine the most appropriate
sound pressure levels for this project,
data from studies which met the
following parameters were considered:
• Pile size and type: 24-inch diameter
steel pipe piles
160 dB re 1 μ Pa (rms).
120 dB re 1 μ Pa (rms).
• Installation and removal method:
Vibratory and/or impact hammer
• Physical environment: Water depth,
sediment type
Details of the physical characteristics
of the waters and substrate off the
JLOTS locations were taken into
consideration for determining the size of
ensonified zones. Source levels were
selected from NAVFAC Atlantic’s
comprehensive dataset based on
similarity to site conditions at JEB Little
Creek-Fort Story (sand with shell debris
sediments, average depth 1–5 meters),
and Camp Lejeune (lower sedimentation
with hard-bottom in some areas, depth
around 7 meters), equipment (i.e., diesel
hammer), and lack of conditions that
might introduce extra noise into the
measurements (e.g., riverine
environments). Calculated averages of
selected source levels used as proxies
for modeling are summarized in Table 4.

Take Zone Size Calculation
wreier-aviles on DSK5TPTVN1PROD with RULES
Modeling sound propagation is useful
in evaluating noise levels at various
distances from the pile driving activity.
The decrease in acoustic intensity as a
sound wave propagates outward from a
source is known as transmission loss
(TL). The formula for transmission loss
is:
TL = B * log10(R1/R2) + C * R1,
Where:
B = logarithmic (predominantly spreading)
loss
C = linear (scattering and absorption) loss
R1 = range from source in meters
R2 = range from driven pile to original
measurement location (generally 10 m
for pile driving activities)
The amount of linear loss (C) is
proportional to the frequency of a
sound. Due to the low frequencies of
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
sound generated by impact and
vibratory pile driving, this factor was
assumed to be zero for all calculations
in this assessment and transmission loss
was calculated using only logarithmic
spreading. Therefore, using practical
spreading (B = 15), the revised formula
for transmission loss is TL = 15 log10
(R1/10).
The practical spreading loss model
(TL = 15 log10 (R1/10)) discussed above
was used to calculate the underwater
propagation of pile driving sound in and
around the three locations. A total of 30
days of pile driving were modeled for
JEB Little Creek-Fort Story and Camp
Lejeune; 20 days of impact driving, and
10 days of vibratory extraction. No noise
mitigation methods (bubble curtains,

Impact driving of each pile is
expected to last no more than 15
minutes. Typically, 6 piles would be
installed each day, for up to 20 days.
Generally, two pile drivers are used, but
not simultaneously: While one is
installing a pile, the other is being
repositioned for the next pile. For
vibratory extraction, the acoustic model
assumed that 12 piles would be
extracted each day, lasting 6 minutes
each, over the course of 10 days.
The range to effects (Table 5) for
underwater noise is assumed to take a
circular shape around the notional pile
bring driven at the furthest offshore
point of the ELCAS (M) (approximately
1,500 ft. [457 m] from shore). Zones
with radii larger than 1,500 ft. (457 m)
will be truncated by the shoreline, and
were modeled as semicircles extending
to the west, north, and east in the case

the beaches at each of the locations

sounds will attenuate as they encounter
land or other solid obstacles. As a result,
the distances calculated may not
actually be attained at the two

Take Number Requested
Based on the size of the areas in
which pile driving and extraction may
exceed established thresholds, the Navy
applied estimated densities for the
bottlenose dolphin and Atlantic spotted
dolphin and the number of active pile
driving days. The result shows that
approximately 50 Northern North
Carolina estuarine system and 60
Southern North Carolina estuarine
system bottlenose dolphins and 50
Western North Atlantic spotted
dolphins could be taken by Level B
behavioral harassment annually from
sound in the water, with a total of 250
Northern North Carolina estuarine
system and 300 Southern North
Carolina estuarine system bottlenose
dolphins and 250 Western North
Atlantic spotted dolphins taken by
Level B behavioral harassment from
sound in the water during the five-year
period of the rule (Table 6). No Level A
takes is expected and none is authorized
due to the low sound intensity from the
proposed JLOTS activities. The annual
percentage of takes of these species/
stocks is less than 6% of each
population.

Analysis and Determinations

Negligible Impact
Negligible impact is ‘‘an impact
resulting from the specified activity that
cannot be reasonably expected to, and is
not reasonably likely to, adversely affect
the species or stock through effects on
annual rates of recruitment or survival’’
(50 CFR 216.103). A negligible impact
finding is based on the lack of likely
adverse effects on annual rates of
recruitment or survival (i.e., populationlevel effects). An estimate of the number
of Level B harassment takes, alone, is
not enough information on which to
base an impact determination. In
addition to considering estimates of the
number of marine mammals that might
be ‘‘taken’’ through behavioral
harassment, NMFS must consider other
factors, such as the likely nature of any
responses (their intensity, duration,
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
etc.), the context of any responses
(critical reproductive time or location,
migration, etc.), as well as the number
and nature of estimated Level A
harassment takes, the number of
estimated mortalities, and effects on
habitat.
To avoid repetition, the following
discussion applies to Northern North
Carolina estuarine system and Southern
North Carolina estuarine system
bottlenose dolphins and Western North
Atlantic spotted dolphins, given that the
best available information indicates that
effects of the specified activity on
individuals of those odontocete stocks
will be similar, and there is no
information about the population size,
status, structure, or habitat use of the
areas to warrant separate discussion.
The Navy’s JLOTS training activity
would involve pile driving and removal
activities during the training exercise.

Elevated noise levels are expected to be
generated as a result of these activities.
However, the source levels generated by
the pile driving and removal activities
are expected be low due to the lowpower hammer being used. In addition,
given the standard operating procedure
of soft starts and required mitigation
and monitoring such as shutdown
measures when marine mammals are
sighted approaching the mitigation
zone, no injuries (Level A harassment)
or mortalities are anticipated to occur as
a result of the Navy’s JLOTS training
activities, and none are authorized. As
described above, marine mammals in
the area would not be exposed to
activities or sound levels which would
result in hearing impairment (TTS or
PTS) or non-auditory physiological
effects.
In-water construction activities would
occur in nearshore shallow waters at the

JEB Little Creek-Fort Story in Virginia
and at Camp Lejeune in North Carolina.
The training areas are not considered
significant habitat for marine mammals.
Marine mammals approaching the
action area would likely be traveling or
opportunistically foraging. There are no
rookeries or major haul-out sites nearby,
foraging hotspots, or other ocean bottom
structure of significant biological
importance to marine mammals that
may be present in the marine waters in
the vicinity of the training areas. The
training areas are not prime habitats for
marine mammals, nor are they
considered areas frequented by marine
mammals. Therefore, behavioral
disturbances that could result from
anthropogenic noise associated with the
JLOTS training activities are expected to
affect only relatively small numbers of
marine mammals on an infrequent basis.
Although it is possible that some
individual marine mammals may be
exposed to sounds from in-water pile
driving activities more than once, the
duration of these multi-exposures is
expected to be low since animals would
be constantly moving in and out of the
area and in-water pile driving activities
would not occur continuously
throughout the day.
Marine mammals may be temporarily
impacted by noise from pile driving and
pile removal activities. These low
intensity, localized, and short-term
noise exposures may cause brief startle
reactions or short-term behavioral
modifications by the animals. These
reactions and behavioral changes are
expected to subside quickly when the
exposures cease. Moreover, marine
mammals are expected to avoid the area
during in-water construction because
animals generally move away from
active sound sources, thereby reducing
exposure and impacts. In addition,
through soft starts, a standard operating
procedure, marine mammals are
expected to move away from a sound
source that is annoying prior to its
becoming potentially injurious, and
detection of marine mammals by
lookouts would enable the
implementation of shutdowns to avoid
injury, serious injury, or mortality. Inwater pile driving and pile removal are
expected to occur for about 20 days and
10 days total annually at each location,
respectively. Repeated exposures of
individuals to levels of sound that may
cause Level B harassment are unlikely
to result in hearing impairment or to
significantly disrupt foraging behavior.
Thus, even repeated Level B harassment
of some small subset of a stock is
unlikely to result in any significant
realized decrease in fitness to those
VerDate Sep<11>2014
15:16 Jun 01, 2015
Jkt 235001
individuals, and thus would not result
in any adverse impact to the stock as a
whole. Level B harassment will be
reduced to the level of least practicable
impact through use of mitigation
measures described herein and, if sound
produced by project activities is
sufficiently disturbing, animals are
likely to simply avoid the project area
while the activity is occurring.
The training areas overlap with
habitat of Northern North Carolina
estuarine system and Southern North
Carolina estuarine system bottlenose
dolphins, and are considered to be
biologically important areas to these
bottlenose dolphin stocks. However, the
brief duration and rare occurrence of the
Navy’s JLOTS activities are expected to
affect only a small number of marine
mammals on an infrequent and limited
basis.
Based on the application and
subsequent analysis, the impact of the
described in-water pile driving activities
may result in, at most, short-term
modification of behavior by small
numbers of marine mammals within the
action area. No injury, serious injury, or
mortality is expected to occur and due
to the nature, degree, and context of the
Level B harassment anticipated, the
activity is not expected to impact rates
of recruitment or survival.
Accordingly, 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 monitoring and mitigation
measures, NMFS finds that the total perstock taking of marine mammals from
the Navy’s JLOTS training activity will
have a negligible impact on the affected
marine mammal species or stocks.
Impact on Availability of Affected
Species for Taking for Subsistence Uses
There are no relevant subsistence uses
of marine mammals implicated by this
action. Therefore, NMFS has
determined that the total taking of
affected species or stocks will not have
any unmitigable adverse impact on the
availability of such species or stocks for
taking for subsistence purposes.
Endangered Species Act (ESA)
No species listed under the ESA are
expected to be affected by pile driving
activities in the JLOTS training area.
Therefore, NMFS has determined that a
section 7 consultation under the ESA is
not required.
NEPA
NMFS has participated as a
cooperating agency on the JLOTS EA,
which was published on March 6, 2015.

The JLOTS EA is posted on NMFS’ Web

NMFS has reviewed the EA and
concluded that the EA includes
alternatives relevant to NMFS’ action of
an incidental take authorization and the
environmental consequences analyzed
reflect NMFS’ action. Therefore, NMFS
determined to adopt the Navy’s EA and
prepared its own Finding of No
Significant Impact. Accordingly, an EIS
is not required and will not be prepared
for this action.
Classification
The Office of Management and Budget
has determined that this rule is not
significant for purposes of Executive
Order 12866.
Pursuant to the Regulatory Flexibility
Act (RFA), the Chief Counsel for
Regulation of the Department of
Commerce has certified to the Chief
Counsel for Advocacy of the Small
Business Administration that this rule
will not have a significant economic
impact on a substantial number of small
entities. The factual basis for this
certification was published with the
proposed rule and is not repeated here.
No comments were received regarding
the economic impact of this final rule.
As a result, a final regulatory flexibility
analysis is not required and one was not
prepared.
The Assistant Administrator for
Fisheries has determined that there is
good cause under the Administrative
Procedure Act (5 U.S.C. 553(d)(3)) to
waive the 30-day delay in the effective
date of the measures contained in this
rule. A 30-day delay in the effective date
of the rule from the date of publication
in the Federal Register would cause an
impracticable interruption to the U.S.
Navy’s scheduled training events.
Congress has mandated that the Chief of
Naval Operations organize, train, and
equip all naval forces for combat (10
U.S.C. 5062). In order to meet the
congressional mandate, the U.S. Navy
must continually train to maintain its
ability to operate in challenging at-sea
environments and conduct military
operations. The training requirements
analyzed in the JLOTS EA will be
implemented immediately into the
training cycle to reinstate Naval Beach
Group TWO’s certification for the
construction of the Elevated Causeway
System—Modular. This training must
occur in order for the Naval Beach
Group TWO to be able report if directed
to an overseas theater of operations.

the mitigation measures contained in
the LOA issued under § 216.106 of this
chapter and § 218.17 must be
implemented. These mitigation
measures include, but are not limited to:
(1) Establishing mitigation zone. (i) A
mitigation zone of 60 yards (55 m)
around the pile being driven must be
established.
(ii) Visual observation must be
conducted starting 30 minutes prior to,

mitigation zone. The exercise must not
commence if concentrations of floating
vegetation (Sargassum) are observed in
the mitigation zone.
(2) Soft starts. (i) Soft starts, or
gradually ramping up the power of pile
driving hammer, must be performed
during impact installation each day.
(ii) During a soft start, an initial set of
strikes from the impact hammer at
reduced energy are performed before it
is able to be operated at full power and
speed.
(3) Shutdown measures. (i) Pile
driving must cease if a marine mammal
is visually detected within or
approaching the mitigation zone.
(ii) Pile driving may resume if any one
of the following conditions is met:
(A) The animal is observed exiting the
mitigation zone,
(B) The animal is thought to have
exited the mitigation zone based on its
course and speed, or
(C) The mitigation zone has been clear
from any additional sightings for a

§ 218.15 Requirements for monitoring and
reporting.
(a) Monitoring measures—(1)
Standard watch personnel. (i) Ships
operated by or for the Navy must have
personnel assigned to stand watch at all
times, day and night, when moving
through the water.
(ii) Watch personnel must undertake
extensive training in accordance with
the U.S. Navy Lookout Training
Handbook or civilian equivalent,
including on-the-job instruction and a
formal Personal Qualification Standard
program (or equivalent program for
supporting contractors or civilians), to
certify that they have demonstrated all
necessary skills (such as detection and
reporting of floating or partially
submerged objects).
(iii) While on watch, watch personnel
must employ visual search techniques,
including the use of binoculars, using a
scanning method in accordance with the
U.S. Navy Lookout Training Handbook
or civilian equivalent.
(iv) After sunset and prior to sunrise,
watch personnel must employ night
visual search techniques, which could
include the use of night vision devices.
(v) A primary duty of watch personnel
is to detect and report all objects and
disturbances sighted in the water that
may be indicative of a threat to the ship
and its crew, such as debris, a
periscope, surfaced submarine, or
surface disturbance.
(vi) Per safety requirements, watch
personnel also report any marine
mammals sighted that have the potential
to be in the direct path of the ship as
a standard collision avoidance
procedure. Because watch personnel are
primarily posted for safety of

navigation, range clearance, and manoverboard precautions, they are not
normally posted while ships are moored
to a pier.
(vii) When anchored or moored to a
buoy, a watch team is still maintained
but with fewer personnel than when
underway.
(viii) When moored or at anchor,
watch personnel may maintain security
and safety of the ship by scanning the
water for any indications of a threat.
(ix) While underway, Navy ships
(with the exception of submarines)
greater than 65 ft. (20 m) in length have
at least two watch personnel; Navy
ships less than 65 ft. (20 m) in length,
surfaced submarines, and contractor
ships have at least one watch person.
While underway, watch personnel are
alert at all times and have access to
binoculars. Due to limited manning and
space limitations, small boats and some
craft transferring cargo from ship to
shore do not have dedicated watch
personnel, and the boat crew is
responsible for maintaining the safety of
the boat and surrounding environment.
(x) All vessels use extreme caution
and proceed at a ‘‘safe speed’’ so they
can take proper and effective action to
avoid a collision with any sighted object
or disturbance and can be stopped
within a distance appropriate to the
prevailing circumstances and
conditions.
(2) Lookouts. (i) Lookouts must
perform similar duties to standard
watch personnel, and are also
responsible for satisfying mitigation
requirements.
(ii) The Navy must have one Lookout
positioned on the platform (which could
include a small boat, the elevated
causeway, or the shore) that must
maximize the potential for sightings
during pile driving and pile removal.
(iii) The Lookout positioned on the
elevated causeway or the shore must be
dedicated solely to diligent observation
of the air and surface of the water. They
must have multiple observation
objectives, which include but are not
limited to detecting the presence of
biological resources and recreational or
fishing boats, observing the mitigation
zone, and monitoring for equipment and
personnel safety concerns.
(iv) A Lookout positioned on a small
boat may include a member of the boat
crew, and may be responsible for tasks
in addition to observing the air or
surface of the water (e.g., navigation of
a rigid hull inflatable boat). However, a
boat Lookout must, to the maximum
extent practicable and consistent with
safety and training requirements,
comply with the observation objectives
described above for a Lookout
PO 00000

positioned on the elevated causeway or
the shore.
(v) Lookouts must also perform visual
observation starting 30 minutes prior to,
during, and 30 minutes after the
exercise within a mitigation zone of 60
yards (55 m) around the pile being
driven.
(3) Integrated comprehensive
monitoring program. (i) The Navy must
use the existing Integrated
Comprehensive Monitoring Program
(ICMP) and its new ‘‘study-based’’
approach.
(ii) [Reserved]
(b) Reporting measures—(1) General
notification of injured or dead marine
mammals. (i) Navy personnel must
ensure that NMFS (regional stranding
coordinator) is notified immediately (or
as soon as clearance procedures allow)
if an injured or dead marine mammal is
found during or shortly after, and in the
vicinity of, any Navy training exercise.
(ii) The Navy must provide NMFS
with species identification 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
photographs or video (if available).
(2) Annual monitoring and exercise
report. (i) Reports from individual
monitoring events, results of analyses,
publications, and periodic progress
reports for specific monitoring projects
must be posted to the Navy’s Marine
Species Monitoring web portal as they
become available.
(ii) Progress and results from all
monitoring activity conducted within
the JLOTS training area must be
summarized in an annual report. This
report must detail the monitoring
protocol, summarize the data recorded
during monitoring, and estimate the
number of marine mammals that may
have been harassed.
(iii) Draft reports should be combined
with the Navy’s Atlantic Fleet Training
and Testing exercise and monitoring
reports and submitted to NMFS for
review by February 13 (for exercises)
and April 1 (for monitoring) each year.
NMFS will review the report and

SUPPLEMENTARY INFORMATION:
Background
Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et se.)
direct the Secretary of Commerce to allow, upon request, the
incidental, but not intentional, taking of small numbers of marine
mammals by U.S. citizens who engage in a specified activity (other than
commercial fishing) within a specified geographical region if certain
findings are made and either regulations are issued or, if the taking
is limited to harassment, a notice of a proposed authorization is
provided to the public for review.
Authorization for incidental takings shall be granted if NMFS finds
that the taking will have a negligible impact on the species or
stock(s), will not have an unmitigable adverse impact on the
availability of the species or stock(s) for subsistence uses (where
relevant), and if the permissible methods of taking and requirements
pertaining to the mitigation, monitoring, and reporting of such takings
are set forth. NMFS has defined ``negligible impact'' in 50 CFR 216.103
as ``an impact resulting from the specified activity that cannot be
reasonably expected to, and is not reasonably likely to, adversely
affect the species or stock through effects on annual rates of
recruitment or survival.''
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'' limitations indicated
above and amended the definition of ``harassment'' as applied to
``military readiness activity'' to mean: ``(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].'' (Section
3(18)(B) of the MMPA.)
Summary of Request
On August 20, 2014, NMFS received an application from the Navy
requesting a letter of authorization (LOA) for the take of bottlenose
and Atlantic spotted dolphins incidental to the Navy's JLOTS training
activities in nearshore waters at the Joint Expeditionary Base (JEB)
Little Creek-Fort Story in Virginia and at Camp Lejeune in North
Carolina. The Navy is requesting regulations that would allow NMFS to
authorize take, via a 5-year LOA, of marine mammals incidental to
training activities. These activities are classified as military
readiness activities. The Navy states that these activities may result
in take of marine mammals from noise from temporary pier construction
associated with the JLOTS training activities. The Navy requests to
take bottlenose and Atlantic spotted dolphins by Level B harassment.
Specified Activity
A detailed description of the Navy's proposed JLOTS activities is
provided in the proposed rule (80 FR 2636; January 20, 2015) and is not
repeated here. No changes were made to the proposed action since the
proposed rule was published.
Comments and Responses
On January 20, 2015 (80 FR 2636), NMFS published a proposed rule to
authorize the taking of marine mammals incidental to the Navy's JLOTS
training activities. During the 30-day public comment period, NMFS
received comments from the Marine Mammal Commission (Commission) and a
private citizen. Comments specific to section 101(a)(5)(A) of the MMPA
and NMFS' analysis of impacts to marine mammals are summarized and
addressed below and/or throughout the final rule.
Comment 1: The Commission recommends that NMFS require the Navy to
submit a proposed monitoring plan in support of JLOTS training
activities, which at the very least should include a brief synopsis of
the projects the Navy plans to conduct, for public review and comment
prior to issuance of the final regulations.
Response 1: The Navy will use the existing Integrated Comprehensive
Monitoring Program and the study-based approach that Navy and NMFS
agreed to during a prior adaptive management session to satisfy
monitoring requirements for the JLOTS MMPA authorization. The Navy's
LOA application provided details on the Integrated Comprehensive
Monitoring Plan, as well as the Web site where the public can obtain
further information on all of the Navy's marine species monitoring work
(https://www.nmfs.noaa.gov/pr/permits/incidental.htm#applications).
To ensure efficient implementation of the Navy's monitoring program
and maintain consistency with how the program is already being
implemented for the Atlantic Fleet Training and Testing (AFTT) MMPA
authorization, the same AFTT adaptive management process and reporting
deadlines will be used for the JLOTS authorization. In fact, the in-
water pile driving associated with JLOTS was originally part of the
AFTT Environmental Impact Statement (EIS) and LOA, and this pile-
driving activity and its associated monitoring requirements already
went through public review and comment during the AFTT EIS and MMPA
process, as JLOTS activities were not removed until the Final Rule and
Final EIS stage.
Table 1 shows Navy projects that help achieve the Integrated
Comprehensive Monitoring Program's top level goals. There may be future
unforeseen budget or other logistical issues that require modification
to study design, scope, or direction of one or more of these projects.
However, the Navy has currently either planned for or is currently
undertaking these projects as described. The first two projects will
investigate the sound source level of pile driving and its effects on
marine species and the remaining four projects help advance scientific
knowledge of presence, density, distribution, and movement of marine
species found in the Chesapeake Bay and along the coasts of Virginia
and North Carolina. Information on these projects and all Navy
monitoring projects can be found at https://www.navymarinespeciesmonitoring.us/.
Therefore, NMFS does not believe that an additional monitoring plan
in support of JLOTS training activities or additional comment period is
warranted.

Comment 2: A private citizen wrote against NMFS issuing the LOA to
the Navy because of concerns that marine mammals will be killed.
Response 2: As described in detail in the proposed rule (80 FR
2636; January 20, 2015), the Navy's proposed JLOTS training activities
would only result in Level B behavioral harassment of bottlenose and
Atlantic spotted dolphins. No injury or mortality is expected, and none
is authorized.
Description of Marine Mammals in the Area of the Specified Activities
There are six marine mammal species under NMFS jurisdiction with
possible or known occurrence in the Navy's JLOTS training area at the
JEB Little Creek-Fort Story in Virginia and at Camp Lejeune in North
Carolina, as indicated in Table 2. Four marine mammal species are
listed under the Endangered Species Act: North Atlantic right whale,
humpback whale, sei whale, and fin whale.

NMFS has reviewed the information compiled by the Navy on the
abundance, status, and distribution of marine mammal species in the
waters of the JLOTS training areas of the North Atlantic coast, which
was derived from peer reviewed literature, the Navy Marine Resource
Assessments, and NMFS Stock Assessment Reports. NMFS considers this
information to be the best available. This information may be viewed in
the Navy's LOA application and the Navy's EA (see Availability).
Additional information is available in the NMFS Stock Assessment
Reports, which may be viewed at: https://www.nmfs.noaa.gov/pr/sars/species.htm.
Fin whales, North Atlantic right whale, humpback whale, and sei
whale are considered rare in the JLOTS training areas. These mysticete
whales tend to be distributed in offshore areas. Occurrences of these
species in the inshore waters off JEB Little Creek-Fort Story or near
shore waters off Camp Lejeune are expected to be rare. Due to their
extremely rare occurrence within the training areas where pile driving
and removal occur, the Navy and NMFS do not anticipate any take of fin,
North Atlantic right, humpback, or sei whales. Therefore, these species
are not addressed further in this document.
Potential Effects of the Specified Activity on Marine Mammals
When considering the effects of various kinds of sound on the
marine environment, it is necessary to understand that different kinds
of marine life are sensitive to different frequencies of sound. Based
on available behavioral data, audiograms have been derived using
auditory evoked potentials, anatomical modeling, and other data. From
this, Southall et al. (2007) designated ``functional hearing groups''
for marine mammals and estimate the lower and upper frequencies of
functional hearing of the groups. The functional groups and the
associated frequencies are indicated below. It should be noted that
animals are less sensitive to sounds at the outer edge of their
functional range and most sensitive to sounds of frequencies towards
the middle of their functional hearing range:
Low frequency cetaceans (13 species of mysticetes):
Functional hearing is estimated to occur between approximately 7 Hz and
30 kHz;
Mid-frequency cetaceans (32 species of dolphins, six
species of larger toothed whales, and 19 species of
[[Page 31314]]
beaked and bottlenose whales): Functional hearing is estimated to occur
between approximately 150 Hz and 160 kHz;
High frequency cetaceans (eight species of true porpoises,
six species of river dolphins, Kogia, the franciscana, and four species
of cephalorhynchids): Functional hearing is estimated to occur between
approximately 200 Hz and 180 kHz;
Phocid pinnipeds in Water: Functional hearing is estimated
to occur between approximately 75 Hz and 100 kHz; and
Otariid pinnipeds in Water: Functional hearing is
estimated to occur between approximately 100 Hz and 40 kHz.
As mentioned previously in this document, only bottlenose dolphin
and Atlantic spotted dolphin are likely to occur in the JLOTS training
areas. Both of these two species are classified as mid-frequency
cetaceans (Southall et al. 2007). Because their hearing frequency range
overlaps with the frequencies associated with pile driving, the Navy
and NMFS determined that in-water pile removal and pile driving during
the JLOTS training activities have the potential to result in
behavioral harassment.
Marine mammals exposed to high-intensity sound repeatedly or for
prolonged periods can experience hearing threshold shift (TS), which is
the reduction of hearing sensitivity in the frequency ranges of the
sound source (Kastak et al. 1999; Schlundt et al. 2000; Finneran et al.
2002; 2005). TS can be permanent (PTS), in which case the reduction of
hearing sensitivity is unrecoverable, or temporary (TTS), in which case
the animal's reduction of hearing sensitivity will recover over time
(Southall et al. 2007). Since marine mammals depend on acoustic cues
for vital biological functions, such as orientation, communication,
finding prey, and avoiding predators, hearing impairment could result
in the reduced ability of marine mammals to detect or interpret
important sounds. Repeated noise exposure that causes TTS could lead to
PTS.
Experiments on a bottlenose dolphin (Tursiops truncatus) and beluga
whale (Delphinapterus leucas) showed that exposure to a single watergun
impulse at a received level of 207 kPa (or 30 psi) peak-to-peak (p-p),
which is equivalent to 228 dB (p-p) re 1 [mu]Pa, resulted in a 7 and 6
dB TTS in the beluga whale at 0.4 and 30 kHz, respectively. Thresholds
returned to within 2 dB of the pre-exposure level within 4 minutes of
the exposure (Finneran et al. 2002). No TTS was observed in the
bottlenose dolphin. Although the source level of one hammer strike for
pile driving is expected to be much lower than the single watergun
impulse cited here, animals being exposed for a prolonged period to
repeated hammer strikes could receive more noise exposure in terms of
sound exposure level (SEL) than from the single watergun impulse
(estimated at 188 dB re 1 [mu]Pa\2\-s) in the aforementioned experiment
(Finneran et al. 2002).
Chronic exposure to excessive, though not high-intensity, noise
could cause masking at particular frequencies for marine mammals that
utilize sound for vital biological functions (Clark et al. 2009).
Masking is the obscuring of sounds of interest by other sounds, often
at similar frequencies. Masking generally occurs when sounds in the
environment are louder than, and of a similar frequency as, auditory
signals an animal is trying to receive. Masking can interfere with
detection of acoustic signals, such as communication calls,
echolocation sounds, and environmental sounds important to marine
mammals. Therefore, under certain circumstances, marine mammals whose
acoustical sensors or environment are being severely masked could also
be impaired.
Masking occurs at the frequency band which the animals utilize.
Since noise generated from in-water pile removal and driving is mostly
concentrated at low frequency ranges, it may have little effect on
high-frequency echolocation sounds by odontocetes (toothed whales).
However, the lower frequency man-made noises are more likely to affect
the detection of communication calls and other potentially important
natural sounds, such as surf and prey noise. The noises may also affect
communication signals when those signals occur near the noise band, and
thus reduce the communication space of animals (e.g., Clark et al.
2009), cause modification in vocalization patterns (e.g., Foote et al.
2004; Holt et al. 2009), and cause increased stress levels (Rolland et
al. 2012).
Masking can potentially impact the species at community,
population, or even ecosystem levels, as well as individual levels.
Masking affects both senders and receivers of the signals and could
have long-term chronic effects on marine mammal species and
populations. Recent science suggests that low frequency ambient sound
levels in the world's oceans have increased by as much as 20 dB (more
than 3 times, in terms of SPL) from pre-industrial periods, and most of
these increases are from distant shipping (Hildebrand 2009). All
anthropogenic noise sources, such as those from vessel traffic and pile
removal and driving, contribute to the elevated ambient noise levels,
thus intensifying masking.
The sum of noise from the Navy's JLOTS training activities is
confined to a limited area and is temporary and intermittent;
therefore, the noise generated is not expected to contribute to
increased ocean ambient noise. In addition, due to shallow water depths
in the training area, underwater sound propagation of low-frequency
sound (which is the major noise source from pile driving) is expected
to be poor.
Finally, in addition to TS and masking, exposure of marine mammals
to certain sounds could lead to behavioral disturbance (Richardson et
al. 1995), such as: Changing durations of surfacing and dives, number
of blows per surfacing, or moving direction and/or speed; reduced/
increased vocal activities; changing/cessation of certain behavioral
activities, such as socializing or feeding; visible startle response or
aggressive behavior, such as tail/fluke slapping or jaw clapping; and
avoidance of areas where noise sources are located.
The biological significance of many of these behavioral
disturbances is difficult to predict, especially if the detected
disturbances appear minor. However, the consequences of behavioral
modification could be expected to be biologically significant at the
population level if the change affects growth, survival, or
reproduction. Some of these types of significant behavioral
modifications include:
Drastic change in diving/surfacing patterns (such as those
thought to be causing beaked whale strandings due to exposure to
military mid-frequency tactical sonar);
Extended habitat abandonment due to loss of desirable
acoustic environment; and
Extended cessation of feeding or social interaction.
The onset of behavioral disturbance from anthropogenic noise
depends on both external factors (characteristics of noise sources and
their paths) and the receiving animals (hearing, motivation,
experience, demography), and is therefore difficult to predict
(Southall et al. 2007). In order to give rise to significant/population
level effects we would expect that exposures would have to be prolonged
and over a large area.
Anticipated Effects on Marine Mammal Habitat
No permanent impacts to marine mammal habitat are anticipated to
occur as a result of the training activities. The Navy's JLOTS training
activities would
[[Page 31315]]
not modify the existing habitat. Therefore, no restoration of the
habitat would be necessary. A temporary, small-scale loss of foraging
habitat may occur for marine mammals, if the marine mammals leave the
area during pile extraction and driving activities.
Acoustic energy created during pile driving and removal work would
have the potential to disturb fish within the vicinity of the training
areas. As a result, the affected areas could temporarily lose foraging
value to marine mammals. During pile driving, high noise levels may
exclude fish from the vicinity of the pile driving. Hastings and Popper
(2005) identified several studies that suggest fish will relocate to
avoid areas of damaging noise energy. If fish leave the area of
disturbance, the affected area may have a temporarily decreased
foraging value during impact hammering and vibratory removal of piles.
The duration of fish avoidance of this area after pile driving
stops is unknown. However, the affected area represents an extremely
small portion of the total foraging range of marine mammals that may be
present in and around the project area.
Because of the short duration of the activities and the relatively
small area of the habitat that may be affected, the impacts to marine
mammals and the food sources that they utilize are not expected to
cause significant or long-term consequences for individual marine
mammals or marine mammal populations.
Mitigation
In order to issue an incidental take authorization (ITA) under
section 101(a)(5)(A) of the MMPA, NMFS must set forth the ``permissible
methods of taking pursuant to such activity, and other means of
effecting the least practicable adverse impact on such species or stock
and its habitat, paying particular attention to rookeries, mating
grounds, and areas of similar significance.''
The NDAA of 2004 amended the MMPA as it relates to military
readiness activities 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 JLOTS LOA
application are considered military readiness activities. Details of
the mitigation measures are provided below. They have not changed from
the mitigation we proposed in the proposed rule.
Impact Pile Driving Ramp-Up
Soft starts are performed during impact installation each day.
During a soft start, an initial set of strikes from the impact hammer
at reduced energy is performed before the hammer is able to be operated
at full power and speed. The energy reduction of an individual hammer
cannot be quantified because they vary by individual driver. Also, the
number of strikes will vary at reduced energy because raising the
hammer at less than full power and then releasing it results in the
hammer ``bouncing'' as it strikes the pile resulting in multiple
``strikes.'' A benefit of a soft start is that marine species in the
vicinity are provided a ``warning,'' giving them an opportunity to
leave the area at the first occurrence of the noise, prior to full
capacity operation. This is expected to reduce any potential exposures
to underwater noise levels that could cause behavioral disturbance or
injury.
Mitigation Zone and Shutdown Measure
The Navy will establish a mitigation zone of 60 yards (55 m) around
the pile being driven. Visual observation will be conducted starting 30
minutes prior to, during, and until 30 minutes after the exercise
within the mitigation zone. The exercise will not commence if
concentrations of floating vegetation (Sargassum) are observed in the
mitigation zone.
Pile driving will cease if a marine mammal is visually detected
within the mitigation zone. Pile driving may re[hyphen]commence if any
one of the following conditions is met: (1) The animal is observed
exiting the mitigation zone, (2) the animal is thought to have exited
the mitigation zone based on its course and speed, or (3) the
mitigation zone has been clear from any additional sightings for a
period of 30 minutes.
Marine Species Awareness Training
Consistent with current requirements, all personnel standing watch
on the bridge, Commanding Officers, Executive Officers, and Lookouts
will successfully complete the Marine Species Awareness Training prior
to standing watch or serving as a Lookout. The training is designed to
improve the effectiveness of visual observations for marine resources,
including marine mammals. The training provides information on sighting
cues, visual observation tools and techniques, and sighting
notification procedures.
Vessels
Vessels will avoid approaching marine mammals head on and will
maneuver to maintain a mitigation zone of 500 yards (457 m) around
observed whales and 200 yards (183 m) around all other marine mammals
(except bow riding dolphins), providing it is safe to do so.
North Atlantic Right Whale Mid-Atlantic Migration Corridor
A North Atlantic right whale migratory route is located off the
mid-Atlantic coast of the United States. When transiting within the
following areas from November 1 through April 30, which correspond to
the portions of the JLOTS study area where a vessel speed limit applies
to non-federal vessels, the Navy will practice increased vigilance,
exercise extreme caution, and proceed at the slowest speed that is
consistent with safety, mission, and training objectives:
Chesapeake Bay: Within a 20 nm radius of the following (as
measured seaward from the COLREGS lines): 37[deg]00'36.9'' North/
075[deg]57'50.5'' West.
Morehead City, North Carolina: Within a 20 nm radius of
the following (as measured seaward from the COLREGS lines):
34[deg]41'32.0'' North/076[deg]40'08.3'' West.
Wilmington, North Carolina, through South Carolina, and to
Brunswick, Georgia: Within a continuous area 20 nautical miles from
shore and west back to shore bounded by 34[deg]10'30'' North/
077[deg]49'12'' West; 33[deg]56'42'' North/077[deg]31'30'' West;
33[deg]36'30'' North/077[deg]47'06'' West; 33[deg]28'24'' North/

Mitigation Conclusions
NMFS has carefully evaluated the applicant's proposed mitigation
measures and considered a range of other measures in the context of
ensuring that NMFS prescribes the means of effecting the least
practicable adverse impact on the affected marine mammal species and
stocks and their habitat. No additional mitigation measures were
recommended during the public comment period on the rule. Our
evaluation of potential measures included consideration of the
following factors in relation to one another:
The manner in which, and the degree to which, the
successful implementation of the measure is expected to minimize
adverse impacts to marine mammals;
The proven or likely efficacy of the specific measure to
minimize adverse impacts as planned; and
The practicability of the measure for applicant
implementation, including consideration of personnel safety,
practicality of implementation, and
[[Page 31316]]
impact on the effectiveness of the military readiness activity.
Any mitigation measure(s) prescribed by NMFS should be able to
accomplish, have a reasonable likelihood of accomplishing (based on
current science), or contribute to the accomplishment of one or more of
the general goals listed below:
1. Avoidance or minimization of injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may contribute to this goal).
2. A reduction in the numbers of marine mammals (total number or
number at biologically important time or location) exposed to received
levels of noise, or other activities expected to result in the take of
marine mammals (this goal may contribute to 1, above, or to reducing
harassment takes only).
3. A reduction in the number of times (total number or number at
biologically important time or location) individuals would be exposed
to received levels of noise, or other activities expected to result in
the take of marine mammals (this goal may contribute to 1, above, or to
reducing harassment takes only).
4. A reduction in the intensity of exposures (either total number
or number at biologically important time or location) to received
levels of noise, or other activities expected to result in the take of
marine mammals (this goal may contribute to 1, above, or to reducing
the severity of harassment takes only).
5. Avoidance or minimization of adverse effects to marine mammal
habitat, paying special attention to the food base, activities that
block or limit passage to or from biologically important areas,
permanent destruction of habitat, or temporary destruction/disturbance
of habitat during a biologically important time.
6. For monitoring directly related to mitigation--an increase in
the probability of detecting marine mammals, thus allowing for more
effective implementation of the mitigation.
NMFS has determined that the mitigation measures provide the means
of effecting the least practicable adverse impact 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.
Monitoring and Reporting
In order to issue an ITA for an activity, section 101(a)(5)(A) of
the MMPA states that NMFS must set forth ``requirements pertaining to
the monitoring and reporting of such taking.'' The MMPA implementing
regulations at 50 CFR 216.104(a)(13) indicate that requests for LOAs
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.
Monitoring measures prescribed by NMFS should accomplish one or
more of the following general goals:
1. An increase in the probability of detecting marine mammals, both
within the mitigation zone (thus allowing for more effective
implementation of the mitigation) and in general to generate more data
to contribute to the analyses mentioned below.
2. An increase in our understanding of how many marine mammals are
likely to be exposed to levels of noise that we associate with specific
adverse effects, such as behavioral harassment, TTS, or PTS.
3. An increase in our understanding of how marine mammals respond
to stimuli expected to result in take and how anticipated adverse
effects on individuals (in different ways and to varying degrees) may
impact the population, species, or stock (specifically through effects
on annual rates of recruitment or survival) through any of the
following methods:
a. Behavioral observations in the presence of stimuli compared to
observations in the absence of stimuli (need to be able to accurately
predict received level, distance from source, and other pertinent
information).
b. Physiological measurements in the presence of stimuli compared
to observations in the absence of stimuli (need to be able to
accurately predict received level, distance from source, and other
pertinent information).
c. Distribution and/or abundance comparisons in times or areas with
concentrated stimuli versus times or areas without stimuli.
4. An increased knowledge of the affected species.
5. An increase in our understanding of the effectiveness of certain
mitigation and monitoring measures.
Monitoring Measures
(1) Standard Watch Personnel
Ships operated by or for the Navy shall have personnel assigned to
stand watch at all times, day and night, when moving through the water
(underway). Watch personnel shall undertake extensive training in
accordance with the U.S. Navy Lookout Training Handbook or civilian
equivalent, including on-the-job instruction and a formal Personal
Qualification Standard program (or equivalent program for supporting
contractors or civilians), to certify that they have demonstrated all
necessary skills (such as detection and reporting of floating or
partially submerged objects). Watch personnel are composed of officers,
enlisted men and women, and civilian equivalents. Their duties may be
performed in conjunction with other job responsibilities, such as
navigating the ship or supervising other personnel. While on watch,
personnel employ visual search techniques, including the use of
binoculars, using a scanning method in accordance with the U.S. Navy
Lookout Training Handbook or civilian equivalent. After sunset and
prior to sunrise, watch personnel employ night visual search
techniques, which could include the use of night vision devices.
A primary duty of watch personnel is to detect and report all
objects and disturbances sighted in the water that may be indicative of
a threat to the ship and its crew, such as debris, a periscope,
surfaced submarine, or surface disturbance. Per safety requirements,
watch personnel also report any marine mammals sighted that have the
potential to be in the direct path of the ship as a standard collision
avoidance procedure. Because watch personnel are primarily posted for
safety of navigation, range clearance, and man-overboard precautions,
they are not normally posted while ships are moored to a pier. When
anchored or moored to a buoy, a watch team is still maintained but with
fewer personnel than when underway.
While underway, Navy ships greater than 65 ft. (20 m) in length
have at least two watch personnel; Navy ships less than 65 ft. (20 m)
in length and contractor ships have at least one watch person. While
underway, watch personnel are alert at all times and have access to
binoculars. Due to limited manning and space limitations, small boats
and some craft transferring cargo from ship to shore do not have
dedicated watch personnel, and the boat crew is responsible for
maintaining the safety of the boat.
All vessels use extreme caution and proceed at a ``safe speed'' so
they can take proper and effective action to avoid a collision with any
sighted object or disturbance and can be stopped within a distance
appropriate to the prevailing circumstances and conditions.
[[Page 31317]]
(2) Lookouts
Lookouts perform similar duties to standard watch personnel, and
are also responsible for satisfying mitigation requirements. The Navy
will have one Lookout positioned on the platform (which could include a
small boat, the elevated causeway, or the shore) that will maximize the
potential for sightings during pile driving and pile removal.
The Lookout positioned on the elevated causeway or the shore will
be dedicated solely to diligent observation of the air and surface of
the water. They will have multiple observation objectives, which
include but are not limited to detecting the presence of biological
resources and recreational or fishing boats, observing the mitigation
zone, and monitoring for equipment and personnel safety concerns. Due
to small boat manning and space restrictions, a Lookout positioned on a
small boat may include a member of the boat crew, and may be
responsible for tasks in addition to observing the air or surface of
the water (e.g., navigation of a rigid hull inflatable boat). However,
a boat Lookout will, to the maximum extent practicable and consistent
with safety and training requirements, comply with the observation
objectives described above for a Lookout positioned on the elevated
causeway or the shore.
Lookouts will also perform visual observation starting 30 minutes
prior to, during, and until 30 minutes after the exercise within a
mitigation zone of 60 yards (55 m) around the pile being driven.
Integrated Comprehensive Monitoring Program
The Navy will use the existing Integrated Comprehensive Monitoring
Program (ICMP) and its new ``study-based'' approach to satisfy
monitoring requirements for the JLOTS MMPA authorization. To ensure
efficient implementation of the program and maintain consistency with
how the program is currently being implemented for the Atlantic Fleet
Training and Testing (AFTT) MMPA authorization, Navy will use the same
AFTT adaptive management process and reporting deadlines for the JLOTS
authorization.
The ICMP is intended to coordinate monitoring efforts across all
regions where the Navy trains and tests and to allocate the most
appropriate level and type of effort for each range complex (U.S.
Department of the Navy 2010). Originally, the Navy monitoring program
was composed of a collection of ``range-specific'' monitoring plans,
each developed individually as part of Marine Mammal Protection Act and
Endangered Species Act compliance processes as environmental
documentation was completed. These individual plans established
specific monitoring requirements for each range complex and were
collectively intended to address the ICMP top-level goals. More
information is provided in the Federal Register notice for the propose
rule (80 FR 2636; January 20, 2015).
Past and Current Monitoring in the Navy JLOTS Training Areas
NMFS has not previously issued incidental take authorizations to
the Navy concerning its JLOTS training on the Atlantic coast.
Therefore, no past and current monitoring is available.
Reporting
In order to issue an ITA for an activity, section 101(a)(5)(A) of
the MMPA states that NMFS must set forth ``requirements pertaining to
the monitoring and reporting of such taking.'' Effective reporting is
critical both to compliance as well as ensuring that the most value is
obtained from the required monitoring. Reports from individual
monitoring events, results of analyses, publications, and periodic
progress reports for specific monitoring projects will be posted to the
U.S. Navy Marine Species Monitoring web portal as they become
available. For the Navy's JLOTS LOA, NMFS requires the following
reporting measures to be implemented:
(1) General Notification of Injured or Dead Marine Mammals
Navy personnel will ensure that NMFS (regional stranding
coordinator) is notified immediately (or as soon as clearance
procedures allow) if an injured or dead marine mammal is found during
or shortly after, and in the vicinity of, any Navy training exercise.
The Navy will provide NMFS with species identification 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 photographs or video (if available).
(2) Annual Monitoring and Exercise Report
As noted above, reports from individual monitoring events, results
of analyses, publications, and periodic progress reports for specific
monitoring projects would be posted to the Navy's Marine Species
Monitoring web portal as they become available. Progress and results
from all monitoring activity conducted within the JLOTS training area
would be summarized in an annual report. This report shall detail the
monitoring protocol, summarize the data recorded during monitoring, and
estimate the number of marine mammals that may have been harassed.
Draft reports should be combined with the Navy's Atlantic Fleet
Training and Testing exercise and monitoring reports and submitted to
NMFS for review by February 13 (for exercises) and April 1 (for
monitoring) each year. NMFS would review the report and provide
comments for incorporation within 3 months.
Estimated Take of Marine Mammals
In the potential effects section, NMFS' analysis identified a
variety of impacts that could potentially result from exposure to noise
during the Navy's JLOTS training activities. In this section, we will
relate the potential effects to marine mammals from these sound sources
to the MMPA definitions of Level A and Level B Harassment and attempt
to quantify the effects that might occur from the specific training
activities that the Navy proposes in the JLOTS training areas.
Definition of Harassment
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].
As discussed above, in-water pile removal and pile driving
(vibratory and impact) generate loud noises that could potentially
harass marine mammals in the vicinity of the Navy's JLOTS training
activities.
Currently, NMFS uses 120 dB re 1 [mu] Pa and 160 dB re 1 [mu] Pa at
the received levels for the onset of Level B harassment from non-
impulse (vibratory pile driving and removal) and impulse sources
(impact pile driving) underwater, respectively. Table 3 summarizes the
current NMFS marine mammal take criteria.

------------------------------------------------------------------------
Methods for Estimating Takes
The methods for estimating the number and types of exposure are
described in the sections below, followed by the method for quantifying
exposures of marine mammals to sources of energy exceeding those
threshold values. Exposure of each was determined by:
The potential of each species to be impacted by the
acoustic sources as determined by acoustic criteria for marine mammals.
The potential presence of each species and their estimated
density inside the range to effect.
The range to effect for impact installation and vibratory
extraction (estimated by taking into account the source levels,
propagation loss, and thresholds at which each acoustic criterion is
met).
Potential exposures were calculated by multiplying the density of
each marine mammal species potentially present by the total impacted
area for each threshold value, rounding the result to the closest
integer, and then multiplying that result by the potential number of
days of pile driving.
Underwater Sound From Pile Driving
Sound levels produced by pile driving are greatly influenced by
factors including pile type, driving method, and the physical
environment in which the activity takes place. A number of studies have
examined sound pressure levels recorded from underwater pile driving
projects in California and Washington, creating a large body of data
for impact driving of steel pipe piles.
To determine the most appropriate sound pressure levels for this
project, data from studies which met the following parameters were
considered:
Pile size and type: 24-inch diameter steel pipe piles
Installation and removal method: Vibratory and/or impact
hammer
Physical environment: Water depth, sediment type
Details of the physical characteristics of the waters and substrate
off the JLOTS locations were taken into consideration for determining
the size of ensonified zones. Source levels were selected from NAVFAC
Atlantic's comprehensive dataset based on similarity to site conditions
at JEB Little Creek-Fort Story (sand with shell debris sediments,
average depth 1-5 meters), and Camp Lejeune (lower sedimentation with
hard-bottom in some areas, depth around 7 meters), equipment (i.e.,
diesel hammer), and lack of conditions that might introduce extra noise
into the measurements (e.g., riverine environments). Calculated
averages of selected source levels used as proxies for modeling are
summarized in Table 4.

Take Zone Size Calculation
Modeling sound propagation is useful in evaluating noise levels at
various distances from the pile driving activity. The decrease in
acoustic intensity as a sound wave propagates outward from a source is
known as transmission loss (TL). The formula for transmission loss is:
TL = B * log10(R1/R2) + C *
R1,
Where:
B = logarithmic (predominantly spreading) loss
C = linear (scattering and absorption) loss
R1 = range from source in meters
R2 = range from driven pile to original measurement
location (generally 10 m for pile driving activities)
The amount of linear loss (C) is proportional to the frequency of a
sound. Due to the low frequencies of sound generated by impact and
vibratory pile driving, this factor was assumed to be zero for all
calculations in this assessment and transmission loss was calculated
using only logarithmic spreading. Therefore, using practical spreading
(B = 15), the revised formula for transmission loss is TL = 15
log10 (R1/10).
The practical spreading loss model (TL = 15 log10
(R1/10)) discussed above was used to calculate the
underwater propagation of pile driving sound in and around the three
locations. A total of 30 days of pile driving were modeled for JEB
Little Creek-Fort Story and Camp Lejeune; 20 days of impact driving,
and 10 days of vibratory extraction. No noise mitigation methods
(bubble curtains, cofferdams, etc.) are proposed and therefore no
attenuation was included in the acoustic model.
Impact driving of each pile is expected to last no more than 15
minutes. Typically, 6 piles would be installed each day, for up to 20
days. Generally, two pile drivers are used, but not simultaneously:
While one is installing a pile, the other is being repositioned for the
next pile. For vibratory extraction, the acoustic model assumed that 12
piles would be extracted each day, lasting 6 minutes each, over the
course of 10 days.
The range to effects (Table 5) for underwater noise is assumed to
take a circular shape around the notional pile bring driven at the
furthest offshore point of the ELCAS (M) (approximately 1,500 ft. [457
m] from shore). Zones with radii larger than 1,500 ft. (457 m) will be
truncated by the shoreline, and were modeled as semicircles extending
to the west, north, and east in the case
[[Page 31319]]
of JEB Little Creek-Fort Story; and north, east, and south at Camp
Lejeune since the beaches at each of the locations would represent the
boundary for underwater propagation. The calculated ranges assume no
obstructions, and sounds will attenuate as they encounter land or other
solid obstacles. As a result, the distances calculated may not actually
be attained at the two installations.

Take Number Requested
Based on the size of the areas in which pile driving and extraction
may exceed established thresholds, the Navy applied estimated densities
for the bottlenose dolphin and Atlantic spotted dolphin and the number
of active pile driving days. The result shows that approximately 50
Northern North Carolina estuarine system and 60 Southern North Carolina
estuarine system bottlenose dolphins and 50 Western North Atlantic
spotted dolphins could be taken by Level B behavioral harassment
annually from sound in the water, with a total of 250 Northern North
Carolina estuarine system and 300 Southern North Carolina estuarine
system bottlenose dolphins and 250 Western North Atlantic spotted
dolphins taken by Level B behavioral harassment from sound in the water
during the five-year period of the rule (Table 6). No Level A takes is
expected and none is authorized due to the low sound intensity from the
proposed JLOTS activities. The annual percentage of takes of these
species/stocks is less than 6% of each population.

Analysis and Determinations
Negligible Impact
Negligible impact is ``an impact resulting from the specified
activity that cannot be reasonably expected to, and is not reasonably
likely to, adversely affect the species or stock through effects on
annual rates of recruitment or survival'' (50 CFR 216.103). A
negligible impact finding is based on the lack of likely adverse
effects on annual rates of recruitment or survival (i.e., population-
level effects). An estimate of the number of Level B harassment takes,
alone, is not enough information on which to base an impact
determination. In addition to considering estimates of the number of
marine mammals that might be ``taken'' through behavioral harassment,
NMFS must consider other factors, such as the likely nature of any
responses (their intensity, duration, etc.), the context of any
responses (critical reproductive time or location, migration, etc.), as
well as the number and nature of estimated Level A harassment takes,
the number of estimated mortalities, and effects on habitat.
To avoid repetition, the following discussion applies to Northern
North Carolina estuarine system and Southern North Carolina estuarine
system bottlenose dolphins and Western North Atlantic spotted dolphins,
given that the best available information indicates that effects of the
specified activity on individuals of those odontocete stocks will be
similar, and there is no information about the population size, status,
structure, or habitat use of the areas to warrant separate discussion.
The Navy's JLOTS training activity would involve pile driving and
removal activities during the training exercise. Elevated noise levels
are expected to be generated as a result of these activities. However,
the source levels generated by the pile driving and removal activities
are expected be low due to the low-power hammer being used. In
addition, given the standard operating procedure of soft starts and
required mitigation and monitoring such as shutdown measures when
marine mammals are sighted approaching the mitigation zone, no injuries
(Level A harassment) or mortalities are anticipated to occur as a
result of the Navy's JLOTS training activities, and none are
authorized. As described above, marine mammals in the area would not be
exposed to activities or sound levels which would result in hearing
impairment (TTS or PTS) or non-auditory physiological effects.
In-water construction activities would occur in nearshore shallow
waters at the
[[Page 31320]]
JEB Little Creek-Fort Story in Virginia and at Camp Lejeune in North
Carolina. The training areas are not considered significant habitat for
marine mammals. Marine mammals approaching the action area would likely
be traveling or opportunistically foraging. There are no rookeries or
major haul-out sites nearby, foraging hotspots, or other ocean bottom
structure of significant biological importance to marine mammals that
may be present in the marine waters in the vicinity of the training
areas. The training areas are not prime habitats for marine mammals,
nor are they considered areas frequented by marine mammals. Therefore,
behavioral disturbances that could result from anthropogenic noise
associated with the JLOTS training activities are expected to affect
only relatively small numbers of marine mammals on an infrequent basis.
Although it is possible that some individual marine mammals may be
exposed to sounds from in-water pile driving activities more than once,
the duration of these multi-exposures is expected to be low since
animals would be constantly moving in and out of the area and in-water
pile driving activities would not occur continuously throughout the
day.
Marine mammals may be temporarily impacted by noise from pile
driving and pile removal activities. These low intensity, localized,
and short-term noise exposures may cause brief startle reactions or
short-term behavioral modifications by the animals. These reactions and
behavioral changes are expected to subside quickly when the exposures
cease. Moreover, marine mammals are expected to avoid the area during
in-water construction because animals generally move away from active
sound sources, thereby reducing exposure and impacts. In addition,
through soft starts, a standard operating procedure, marine mammals are
expected to move away from a sound source that is annoying prior to its
becoming potentially injurious, and detection of marine mammals by
lookouts would enable the implementation of shutdowns to avoid injury,
serious injury, or mortality. In-water pile driving and pile removal
are expected to occur for about 20 days and 10 days total annually at
each location, respectively. Repeated exposures of individuals to
levels of sound that may cause Level B harassment are unlikely to
result in hearing impairment or to significantly disrupt foraging
behavior. Thus, even repeated Level B harassment of some small subset
of a stock is unlikely to result in any significant realized decrease
in fitness to those individuals, and thus would not result in any
adverse impact to the stock as a whole. Level B harassment will be
reduced to the level of least practicable impact through use of
mitigation measures described herein and, if sound produced by project
activities is sufficiently disturbing, animals are likely to simply
avoid the project area while the activity is occurring.
The training areas overlap with habitat of Northern North Carolina
estuarine system and Southern North Carolina estuarine system
bottlenose dolphins, and are considered to be biologically important
areas to these bottlenose dolphin stocks. However, the brief duration
and rare occurrence of the Navy's JLOTS activities are expected to
affect only a small number of marine mammals on an infrequent and
limited basis.
Based on the application and subsequent analysis, the impact of the
described in-water pile driving activities may result in, at most,
short-term modification of behavior by small numbers of marine mammals
within the action area. No injury, serious injury, or mortality is
expected to occur and due to the nature, degree, and context of the
Level B harassment anticipated, the activity is not expected to impact
rates of recruitment or survival.
Accordingly, 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 monitoring and
mitigation measures, NMFS finds that the total per-stock taking of
marine mammals from the Navy's JLOTS training activity will have a
negligible impact on the affected marine mammal species or stocks.
Impact on Availability of Affected Species for Taking for Subsistence
Uses
There are no relevant subsistence uses of marine mammals implicated
by this action. Therefore, NMFS has determined that the total taking of
affected species or stocks will not have any unmitigable adverse impact
on the availability of such species or stocks for taking for
subsistence purposes.
Endangered Species Act (ESA)
No species listed under the ESA are expected to be affected by pile
driving activities in the JLOTS training area. Therefore, NMFS has
determined that a section 7 consultation under the ESA is not required.
NEPA
NMFS has participated as a cooperating agency on the JLOTS EA,
which was published on March 6, 2015. The JLOTS EA is posted on NMFS'
Web site: https://www.nmfs.noaa.gov/pr/permits/incidental.htm#applications. NMFS has reviewed the EA and concluded
that the EA includes alternatives relevant to NMFS' action of an
incidental take authorization and the environmental consequences
analyzed reflect NMFS' action. Therefore, NMFS determined to adopt the
Navy's EA and prepared its own Finding of No Significant Impact.
Accordingly, an EIS is not required and will not be prepared for this
action.
Classification
The Office of Management and Budget has determined that this rule
is not significant for purposes of Executive Order 12866.
Pursuant to the Regulatory Flexibility Act (RFA), the Chief Counsel
for Regulation of the Department of Commerce has certified to the Chief
Counsel for Advocacy of the Small Business Administration that this
rule will not have a significant economic impact on a substantial
number of small entities. The factual basis for this certification was
published with the proposed rule and is not repeated here. No comments
were received regarding the economic impact of this final rule. As a
result, a final regulatory flexibility analysis is not required and one
was not prepared.
The Assistant Administrator for Fisheries has determined that there
is good cause under the Administrative Procedure Act (5 U.S.C.
553(d)(3)) to waive the 30-day delay in the effective date of the
measures contained in this rule. A 30-day delay in the effective date
of the rule from the date of publication in the Federal Register would
cause an impracticable interruption to the U.S. Navy's scheduled
training events. Congress has mandated that the Chief of Naval
Operations organize, train, and equip all naval forces for combat (10
U.S.C. 5062). In order to meet the congressional mandate, the U.S. Navy
must continually train to maintain its ability to operate in
challenging at-sea environments and conduct military operations. The
training requirements analyzed in the JLOTS EA will be implemented
immediately into the training cycle to reinstate Naval Beach Group
TWO's certification for the construction of the Elevated Causeway
System--Modular. This training must occur in order for the Naval Beach
Group TWO to be able report if directed to an overseas theater of
operations. Based on the preceding discussion, it is impracticable to
delay implementation of this rule for 30 days. This agency finds good
cause for excepting the 30-
[[Page 31321]]
day delay. The measures contained in this rule will become effective
upon publication.

Sec. 218.12 Permissible methods of taking.
(a) Under Letters of Authorization (LOAs) issued pursuant to Sec.
218.17, the Holder of the Letter of Authorization may incidentally, but
not intentionally, take marine mammals by sound in the water from pile
driving activities within the area described in Sec. 218.10, provided
the activity is in compliance with all terms, conditions, and
requirements of these regulations and the appropriate LOA.
(b) The activities identified in Sec. 218.10(c) must be conducted
in a manner that minimizes, to the greatest extent practicable, any
adverse impacts on marine mammals and their habitat.
(c) The incidental take of marine mammals under the activities
identified in Sec. 218.10(c) is limited to Level B behavioral
harassment:
(1) Bottlenose dolphin (Tursiops truncatus)/Northern North Carolina
Estuarine System: 250 (50 per year);

Sec. 218.13 Prohibitions.
Notwithstanding takings contemplated in Sec. 218.12 and authorized
by an LOA issued under Sec. 216.106 of this chapter and Sec. 218.17,
no person in connection with the activities described in Sec. 218.10
may:
(a) Take any marine mammal not specified in Sec. 218.12(c);
(b) Take any marine mammal specified in Sec. 218.12(c) other than
by incidental take as specified in Sec. 218.12(c);
(c) Take a marine mammal specified in Sec. 218.12(c) if a finding
is made that such taking is having more than a negligible impact on the
species or stocks of such marine mammal; or
(d) Violate, or fail to comply with, the terms, conditions, and
requirements of these regulations or an LOA issued under Sec. 216.106
of this chapter and Sec. 218.17.
Sec. 218.14 Mitigation.
(a) When conducting training and testing activities identified in
Sec. 218.10, the mitigation measures contained in the LOA issued under
Sec. 216.106 of this chapter and Sec. 218.17 must be implemented.
These mitigation measures include, but are not limited to:
(1) Establishing mitigation zone. (i) A mitigation zone of 60 yards
(55 m) around the pile being driven must be established.
(ii) Visual observation must be conducted starting 30 minutes prior
to, during, and until 30 minutes after the ELCAS (M) exercise within
the mitigation zone. The exercise must not commence if concentrations
of floating vegetation (Sargassum) are observed in the mitigation zone.
(2) Soft starts. (i) Soft starts, or gradually ramping up the power
of pile driving hammer, must be performed during impact installation
each day.
(ii) During a soft start, an initial set of strikes from the impact
hammer at reduced energy are performed before it is able to be operated
at full power and speed.
(3) Shutdown measures. (i) Pile driving must cease if a marine
mammal is visually detected within or approaching the mitigation zone.
(ii) Pile driving may resume if any one of the following conditions
is met:
(A) The animal is observed exiting the mitigation zone,
(B) The animal is thought to have exited the mitigation zone based
on its course and speed, or
(C) The mitigation zone has been clear from any additional
sightings for a period of 30 minutes.
(b) Marine species awareness training. (1) All personnel standing
watch on the bridge, Commanding Officers, Executive Officers, and
Lookouts must successfully complete the Marine Species Awareness
Training prior to standing watch or serving as a Lookout.
(2) The Marine Species Awareness Training must be designed to
improve the effectiveness of visual observations for marine resources,
including marine mammals.
(3) The training must provide information on sighting cues, visual
observation tools and techniques, and sighting notification procedures.
(c) Vessels. Vessels must avoid approaching marine mammals head on
and must maneuver to maintain a mitigation zone of 500 yards (457 m)
around observed whales and 200 yards (183 m) around all other marine
mammals (except bow riding dolphins), providing it is safe to do so.
(d) North Atlantic Right Whale Protection. When transiting within
the following areas between November 1 and April 30, the Navy must
practice increased vigilance, exercise extreme
[[Page 31322]]
caution, and proceed at the slowest speed that is consistent with
safety, mission, and training objectives:
(1) Chesapeake Bay: Within a 20 nm radius of the following (as
measured seaward from the COLREGS lines): 37[deg]00'36.9'' North/
075[deg]57'50.5'' West.
(2) Morehead City, North Carolina: Within a 20 nm radius of the
following (as measured seaward from the COLREGS lines):
34[deg]41'32.0'' North/076[deg]40'08.3'' West.
(3) Wilmington, North Carolina, through South Carolina, and to
Brunswick, Georgia: Within a continuous area 20 nautical miles from
shore and west back to shore bounded by 34[deg]10'30'' North/
077[deg]49'12'' West; 33[deg]56'42'' North/077[deg]31'30'' West;
33[deg]36'30'' North/077[deg]47'06'' West; 33[deg]28'24'' North/
078[deg]32'30'' West; 32[deg]59'06'' North/078[deg]50'18'' West;
31[deg]50'00'' North/080[deg]33'12'' West; 31[deg]27'00'' North/
080[deg]51'36'' West.
Sec. 218.15 Requirements for monitoring and reporting.
(a) Monitoring measures--(1) Standard watch personnel. (i) Ships
operated by or for the Navy must have personnel assigned to stand watch
at all times, day and night, when moving through the water.
(ii) Watch personnel must undertake extensive training in
accordance with the U.S. Navy Lookout Training Handbook or civilian
equivalent, including on-the-job instruction and a formal Personal
Qualification Standard program (or equivalent program for supporting
contractors or civilians), to certify that they have demonstrated all
necessary skills (such as detection and reporting of floating or
partially submerged objects).
(iii) While on watch, watch personnel must employ visual search
techniques, including the use of binoculars, using a scanning method in
accordance with the U.S. Navy Lookout Training Handbook or civilian
equivalent.
(iv) After sunset and prior to sunrise, watch personnel must employ
night visual search techniques, which could include the use of night
vision devices.
(v) A primary duty of watch personnel is to detect and report all
objects and disturbances sighted in the water that may be indicative of
a threat to the ship and its crew, such as debris, a periscope,
surfaced submarine, or surface disturbance.
(vi) Per safety requirements, watch personnel also report any
marine mammals sighted that have the potential to be in the direct path
of the ship as a standard collision avoidance procedure. Because watch
personnel are primarily posted for safety of navigation, range
clearance, and man-overboard precautions, they are not normally posted
while ships are moored to a pier.
(vii) When anchored or moored to a buoy, a watch team is still
maintained but with fewer personnel than when underway.
(viii) When moored or at anchor, watch personnel may maintain
security and safety of the ship by scanning the water for any
indications of a threat.
(ix) While underway, Navy ships (with the exception of submarines)
greater than 65 ft. (20 m) in length have at least two watch personnel;
Navy ships less than 65 ft. (20 m) in length, surfaced submarines, and
contractor ships have at least one watch person. While underway, watch
personnel are alert at all times and have access to binoculars. Due to
limited manning and space limitations, small boats and some craft
transferring cargo from ship to shore do not have dedicated watch
personnel, and the boat crew is responsible for maintaining the safety
of the boat and surrounding environment.
(x) All vessels use extreme caution and proceed at a ``safe speed''
so they can take proper and effective action to avoid a collision with
any sighted object or disturbance and can be stopped within a distance
appropriate to the prevailing circumstances and conditions.
(2) Lookouts. (i) Lookouts must perform similar duties to standard
watch personnel, and are also responsible for satisfying mitigation
requirements.
(ii) The Navy must have one Lookout positioned on the platform
(which could include a small boat, the elevated causeway, or the shore)
that must maximize the potential for sightings during pile driving and
pile removal.
(iii) The Lookout positioned on the elevated causeway or the shore
must be dedicated solely to diligent observation of the air and surface
of the water. They must have multiple observation objectives, which
include but are not limited to detecting the presence of biological
resources and recreational or fishing boats, observing the mitigation
zone, and monitoring for equipment and personnel safety concerns.
(iv) A Lookout positioned on a small boat may include a member of
the boat crew, and may be responsible for tasks in addition to
observing the air or surface of the water (e.g., navigation of a rigid
hull inflatable boat). However, a boat Lookout must, to the maximum
extent practicable and consistent with safety and training
requirements, comply with the observation objectives described above
for a Lookout positioned on the elevated causeway or the shore.
(v) Lookouts must also perform visual observation starting 30
minutes prior to, during, and 30 minutes after the exercise within a
mitigation zone of 60 yards (55 m) around the pile being driven.
(3) Integrated comprehensive monitoring program. (i) The Navy must
use the existing Integrated Comprehensive Monitoring Program (ICMP) and
its new ``study-based'' approach.
(ii) [Reserved]
(b) Reporting measures--(1) General notification of injured or dead
marine mammals. (i) Navy personnel must ensure that NMFS (regional
stranding coordinator) is notified immediately (or as soon as clearance
procedures allow) if an injured or dead marine mammal is found during
or shortly after, and in the vicinity of, any Navy training exercise.
(ii) The Navy must provide NMFS with species identification 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 photographs or video (if
available).
(2) Annual monitoring and exercise report. (i) Reports from
individual monitoring events, results of analyses, publications, and
periodic progress reports for specific monitoring projects must be
posted to the Navy's Marine Species Monitoring web portal as they
become available.
(ii) Progress and results from all monitoring activity conducted
within the JLOTS training area must be summarized in an annual report.
This report must detail the monitoring protocol, summarize the data
recorded during monitoring, and estimate the number of marine mammals
that may have been harassed.
(iii) Draft reports should be combined with the Navy's Atlantic
Fleet Training and Testing exercise and monitoring reports and
submitted to NMFS for review by February 13 (for exercises) and April 1
(for monitoring) each year. NMFS will review the report and provide
comments for incorporation within 3 months.
Sec. 218.16 Applications for Letters of Authorization.
To incidentally take marine mammals pursuant to the regulations in
this subpart, the U.S. Navy must apply for and obtain either an initial
LOA in accordance with Sec. 218.17.
Sec. 218.17 Letters of Authorization.
(a) An LOA, unless suspended or revoked, must be valid for a period
of
[[Page 31323]]
time not to exceed the period of validity of this subpart.
(b) Each LOA must set forth:
(1) Permissible methods of incidental taking;
(2) Means of effecting the least practicable adverse impact on the
species, its habitat, and on the availability of the species for
subsistence uses (i.e., mitigation); and
(3) Requirements for mitigation, monitoring and reporting.
(c) Issuance of the LOA will be based on a determination that the
total number of marine mammals taken by the activity as a whole must
have no more than a negligible impact on the affected species or stock
of marine mammal(s).
Sec. 218.18 Modifications to Letters of Authorization.
(a) Except as provided in paragraph (b) of this section, no
substantive modification (including withdrawal or suspension) to the
LOA by NMFS, issued pursuant to Sec. 216.106 of this chapter and Sec.
218.17 and subject to the provisions of this subpart must be made until
after notification and an opportunity for public comment has been
provided.
(b) If the Assistant Administrator determines that an emergency
exists that poses a significant risk to the well-being of the species
or stocks of marine mammals specified in Sec. 218.12(c), an LOA issued
pursuant to Sec. 216.106 of this chapter and Sec. 218.17 may be
substantively modified without prior notification and an opportunity
for public comment. Notification will be published in the Federal
Register within 30 days subsequent to the action.
