SUMMARY:
I. Background
The Southeast Alaska Purse Seine
Salmon Fishery is a commercial fishery
in Alaska state waters and adjacent
Federal waters. It encompasses the
commercial taking of salmon with purse
seine gear, and participation is limited
to fishermen designated by the Alaska
Commercial Fisheries Entry
Commission (CFEC). Congress
authorized a $23.5 million loan to
finance a fishing capacity reduction
program in the Southeast Alaska Purse
Seine Salmon Fishery. NMFS published
proposed program regulations on May
23, 2011 (76 FR 29707), and final
program regulations on October 6, 2011
(76 FR 61986), to implement the
reduction program.
In 2012, NMFS conducted a
referendum to determine the remaining
fishermen’s willingness to repay a $13.1
million fishing capacity reduction loan
to remove 64 permits. After a majority
of permit holders approved the loan,
NMFS disbursed payments to the
successful bidders and began collecting
fees to repay the loan.
In August 2016, the Southeast
Revitalization Association (SRA)
submitted a second capacity reduction
plan to NMFS and NMFS approved the
second plan in October 2016. Since only
$13.1 million was expended from the
total loan amount, $10.4 remains
available. Approval of this second
referendum would have resulted in a
second loan of $5.8 million and
permanently retired an additional 22
permits from the fishery. The final
regulations required NMFS to provide
public notice before conducting a
referendum to determine the industry’s
willingness to repay a second fishing
capacity reduction loan to purchase the
permits identified in the second
reduction plan.
Comments on the proposed
referendum were accepted until 5 p.m.
EST December 7, 2016. Between
November 14 and November 17, 2016,
NMFS held a series of public meetings
with Southeast Alaska purse seine
salmon permit holders and interested
individuals. The meetings were held in
Sitka, AK, Ketchikan, AK, Petersburg,
AK, and Seattle, WA.

II. Present Status
As of October 21, 2016, there were
315 permits in the fishery designated as
S01A by CFEC. These permanent permit
holders were eligible to vote in this
second referendum. NMFS mailed
referendum information, voting
instructions, and a referendum ballot to
each of the permit owners. The
referendum voting period commenced
December 13, 2016 and ended on
January 13, 2017. Any votes received by
NMFS after 5 p.m. on January 13, 2017,
were not counted. NMFS issued 315
ballots. 50 CFR 600.1107 (e)(3)(ii), states
that ‘‘a successful referendum by a
majority of the Permit Holders in the
Reduction Fishery shall bind all parties
and complete the reduction process,’’
Therefore, a minimum of 158 ballots in
favor of the buyback program was
necessary to approve the new fees.
NMFS received 180 (57%) timely and
valid ballots. 132 were for approving the
proposed buyback. As a result, the
proposed buyback referendum was not
successful and the second buyback loan
was not approved.

Weapon Systems Evaluation Program
(Maritime WSEP) within the Eglin Gulf
Test and Training Range (EGTTR) in the
Gulf of Mexico from February 4, 2017
through February 3, 2018. Eglin AFB’s
activities are military readiness
activities per the MMPA, as amended by
the National Defense Authorization Act
(NDAA) for Fiscal Year 2004.
DATES: Effective February 4, 2017
through February 3, 2018.

SUPPLEMENTARY INFORMATION:
Background
Sections 101(a)(5)(A) and (D) of the
Marine Mammal Protection Act of 1972,
as amended (MMPA; 16 U.S.C. 1361 et
seq.) direct the Secretary of Commerce
to allow, upon request, the incidental,
but not intentional, taking of small
numbers of marine mammals of a
species or population stock, by U.S.
citizens who engage in a specified
activity (other than commercial fishing)
within a specified geographical region
if, after NMFS provides a notice of a
proposed authorization to the public for
review and comment and that NMFS
makes certain findings.
An Authorization for incidental
takings for marine mammals 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 taking 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.’’

Where there is the potential for
serious injury or death, the allowance of
incidental taking requires promulgation
of regulations under section
101(a)(5)(A). Subsequently, a Letter (or
Letters) of Authorization may be issued
as governed by the prescriptions
established in such regulations,
provided that the level of taking will be
consistent with the findings made for
the total taking allowable under the
specific regulations. Under section
101(a)(5)(D), NMFS may authorize
incidental taking by harassment only
(i.e., no serious injury or mortality) for
periods of not more than one year,
pursuant to requirements and
conditions contained within an
Incidental Harassment Authorization
(IHA). The promulgation of regulations
or issuance of IHAs (with their
associated prescripted mitigation,
monitoring, and reporting) requires
notice and opportunity for public
comment.
The NDAA (Pub. L. 108–136)
removed the ‘‘small numbers’’ and
‘‘specified geographical region’’
limitations indicated earlier and
amended the definition of harassment as
it applies to a ‘‘military readiness
activity’’ to read as follows (section
3(18)(B) of the MMPA): (i) Any act that
injures or has the significant potential to
injure a marine mammal or marine
mammal stock in the wild (Level A
Harassment); or (ii) any act that disturbs
or is likely to disturb a marine mammal
or marine mammal stock in the wild by
causing disruption of natural behavioral
patterns, including, but not limited to,
migration, surfacing, nursing, breeding,
feeding, or sheltering, to a point where
such behavioral patterns are abandoned
or significantly altered (Level B
Harassment).
Summary of Request
On February 4, 2016, we issued an
Authorization to Eglin AFB to take
marine mammals, by harassment,
incidental to a Maritime WSEP within
the EGTTR in the Gulf of Mexico from
February 4, 2016 through February 3,
2017 (see 81 FR 7307; February 11,
2016). These missions were very similar
to previous Maritime WSEP mission
activities for which incidental
harassment authorizations were issued
the previous year (80 FR 17394; April 1,
2015). On September 19, 2016, we
received a renewal request for an
Authorization from Eglin AFB to
continue the missions authorized in
2016. We considered the revised
renewal request as adequate and
complete on September 27, 2016.
Due to the ongoing nature of these
activities, as well as the fact that other
VerDate Sep<11>2014
18:44 Feb 14, 2017
Jkt 241001
mission activities are conducted within
the EGTTR, we have discussed
developing a rulemaking to encompass
all mission activities in the EGTTR, and
anticipate that the Maritime WSEP
activities will be part of that future
rulemaking. However, this
Authorization is being granted due to
timing constraints to ensure that these
activities are in compliance with the
MMPA while the future rulemaking is
in process.
Eglin AFB will conduct Maritime
WESP missions within the EGTTR
airspace over the Gulf of Mexico within
Warning Area 151 (W–151), specifically
within sub-area W–151A (see Figure
2–1 of Eglin AFB’s application and
Figure 1 below). The Maritime WSEP
training activities are planned to occur
during daylight hours in February and
March 2017, however, the activities
could occur between February 4, 2017,
and February 3, 2018.
Eglin AFB will use multiple types of
live munitions (e.g., gunnery rounds,
rockets, missiles, and bombs) against
small boat targets in the EGTTR. These
activities qualify as military readiness
activities.
The following aspects of the Maritime
WSEP training activities have the
potential to take marine mammals:
Exposure to impulsive noise and
pressure waves generated by live
ordnance detonation at or near the
surface of the water. Take, by Level B
harassment, of individuals of common
bottlenose dolphin or Atlantic spotted
dolphin could potentially result from
the specified activity. Additionally,
although NMFS does not expect it to
occur, Eglin AFB has also requested
authorization for Level A harassment of
up to four individuals of either common
bottlenose dolphins (2) or Atlantic
spotted dolphins (1). Therefore, Eglin
AFB requested authorization to take
individuals of two cetacean species by
Level A and Level B harassment.
Eglin AFB’s Maritime WSEP training
activities may potentially impact marine
mammals at or near the water surface in
the absence of mitigation. Marine
mammals could potentially be harassed,
injured, or killed by exploding and nonexploding projectiles, and falling debris.
However, based on analyses provided in
Eglin AFB’s 2016 application, Eglin
AFB’s previous applications and
Authorizations, Eglin AFB’s EA, and
past monitoring reports for the
authorized activities conducted in
February and March 2016 and 2015, and
for reasons discussed later in this
document, we do not anticipate that
Eglin AFB’s Maritime WSEP activities
will result in any serious injury or
mortality to marine mammals.

For Eglin AFB, this will be the third
such Maritime WSEP Authorization
following the Authorization issued
effective from February 4, 2016, through
February 3, 2017 (see 81 FR 7307;
February 11, 2016). This Authorization
will be effective from February 4, 2017,
through February 3, 2018. The
monitoring report associated with the
2016 Authorization is available at
www.nmfs.noaa.gov/pr/permits/
incidental/military.htm and provides
additional environmental information
related to issuance of this
Authorization.
Description of the Specified Activity
Overview
Eglin AFB will conduct live ordnance
testing and training in the EGTTR
within the Gulf of Mexico as part of the
Maritime WSEP operational testing
missions. The Maritime WSEP test
objectives are to evaluate maritime
deployment data, evaluate tactics,
techniques and procedures, and to
determine the impact of techniques and
procedures on combat Air Force
training. The need to conduct this type
of testing has developed in response to
increasing threats at sea posed by
operations conducted from small boats,
which can carry a variety of weapons,
can form in large or small numbers, and
may be difficult to locate, track, and
engage in the marine environment.
Because of limited Air Force aircraft and
munitions testing on engaging and
defeating small boat threats, Eglin AFB
will employ live munitions against boat
targets in the EGTTR in order to
continue development of techniques
and procedures to train Air Force strike
aircraft to counter small maneuvering
surface vessels.
Dates and Duration
Eglin AFB will schedule up to eight
Maritime WSEP training missions
occurring during a one-week period in
February 2017 and a one-week period in
March 2017. The missions will occur for
up to four hours each day during the
morning hours, with multiple live
munitions being released per day.
However, the Authorization is effective
to cover those activities anytime during
the period from February 4, 2017
through February 3, 2018.
Specified Geographic Region
The specific planned mission location
is approximately 17 miles (mi) (27.3
kilometers (km)) offshore from Santa
Rosa Island, Florida, in nearshore
waters of the continental shelf in the
Gulf of Mexico. All activities will place
within the EGTTR, defined as the
E:\FR\FM\15FEN1.SGM
15FEN1
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
10749
airspace over the Gulf of Mexico
controlled by Eglin AFB, beginning at a
point 3 nautical miles (nmi) (3.5 mi; 5.5
km) from shore. The EGTTR consists of
subdivided blocks including Warning
Area 151 (W–151) where the activities
will occur, specifically in sub-area W–
151A (shown in Figure 1).
W–151: The inshore and offshore
boundaries of W–151 are roughly
parallel to the shoreline contour. The
shoreward boundary is 3 nmi (3.5 mi;
5.5 km) from shore, while the seaward
boundary extends approximately 85 to
100 nmi (97.8 mi; 157.4 km to 115 mi;
185.2 km) offshore, depending on the
specific location. W–151 covers a
surface area of approximately 10,247
square nmi (nmi2) (13,570 square mi
(mi2); 35,145 square km (km2)), and
includes water depths ranging from
about 20 to 700 meters (m) (65.6 to
2296.6 feet (ft)). This range of depth
includes continental shelf and slope
waters. Approximately half of W–151
lies over the shelf.
W–151A: W–151A extends
approximately 60 nmi (69.0 mi; 111.1
km) offshore and has a surface area of
2,565 nmi2 (3,396.8 mi2; 8,797 km2).
Water depths range from about 30 to 350
m (98.4 to 1148.2 ft) and include
continental shelf and slope zones.
However, most of W–151A occurs over
the continental shelf, in water depths
less than 250 m (820.2 ft). Maritime
WSEP training missions will occur in
the shallower, northern inshore portion
of the sub-area, in a water depth of
about 35 m (114.8 ft).
Detailed Description of Activities
inert and live munitions from fighter
and bomber aircraft, unmanned aerial
vehicles, and gunships against small,
static, towed, and remotely-controlled
boat targets. Munition types include
bombs, missiles, rockets, and gunnery
rounds (Table 1).

The Maritime WSEP training
activities involve detonations above the
water, near the water surface, and under
water within the EGTTR. However,
because the tests will focus on weapons/
target interaction, Eglin AFB will not
specify a particular aircraft for a given
test as long as it meets the delivery
parameters.
Eglin AFB will deploy the munitions
against static, towed, and remotelycontrolled boat targets within the W–
151A. Eglin AFB will operate the
remote-controlled boats from an
instrumentation barge (i.e., the Gulf
Range Armament Test Vessel (GRATV))
anchored on site within the test area.
The GRATV provides a platform for
video cameras and weapons-tracking
equipment.

At least two ordnance delivery aircraft
will participate in each live weapons
release training mission, which lasts
approximately four hours. Before
delivering the ordnance, mission aircraft
will make a dry run over the target area
to ensure that it is clear of commercial
and recreational boats. Jets will fly at a
minimum air speed of 300 knots
(approximately 345 miles per hour,
depending on atmospheric conditions)
and at a minimum altitude of 305 m
(1,000 ft). Due to the limited flyover
duration and potentially high speed and
altitude, the pilots will not participate
in visual surveys for protected species.

Comments and Responses
A notice of receipt of Eglin AFB’s
application and NMFS’ proposal to
issue an Authorization to the U.S. Air
Force, Eglin AFB, published in the
Federal Register on November 21, 2016
(81 FR 83209). During the 30-day public
comment period, NMFS received
comments from the Marine Mammal
PO 00000
Frm 00017
Fmt 4703
Sfmt 4703
Commission (MMC) and one concerned
citizen. Following, are the comments
received from the MMC and the
concerned citizen, as well as NMFS’
responses.
MMC Comment 1: MMC
recommended that NMFS (1) follow
NMFS policy of a 24-hour reset for
enumerating the number of each species
that could be taken during the proposed
activities; (2) apply standard rounding
rule before summing the numbers of
estimated takes across days; and (3) for
species that have the potential to be
taken but model-estimated or calculated
takes round to zero, use group size to
inform the take estimates—The MMC
recommended that NMFS use these
methods consistently for all future
incidental take authorizations.
Response: Calculating predicted take
is not an exact science, and there are
E:\FR\FM\15FEN1.SGM
15FEN1
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
arguments for taking different
mathematical approaches in different
situations and for making qualitative
adjustments in other situations. NMFS
is currently engaged in developing a
protocol to guide more consistent take
calculations given certain
circumstances. However, we believe
that the method used here supports the
most appropriate take estimate for this
action and does not run counter to any
‘‘24-hour reset policy.’’
MMC Comment 2: The MMC states
that Eglin AFB has used, and proposes
to continue the use of live-feed video
cameras to supplement its effectiveness
in detecting marine mammals when
implementing mitigation measures.
However, the MMC is not convinced
that those measures are sufficient to
effectively monitor for marine mammals
entering the training areas during the
30-minute timeframe prior to
detonation. In addition, the MMC states
that it does not believe that Eglin AFB
can deem the Level A harassment zone
clear of marine mammals when using
only three video cameras for
monitoring. Thus, the MMC
recommends that NMFS require Eglin
AFB to (1) supplement its mitigation
measures with passive acoustic
monitoring and (2) determine the
effectiveness of its suite of mitigation
measures for activities at Eglin prior to
incorporating presumed mitigation
effectiveness into its take estimation
analyses or negligible impact
determinations.
Response: NMFS has worked closely
with Eglin AFB over the past several
Authorization cycles to develop proper
mitigation, monitoring, and reporting
requirements designed to minimize and
detect impacts from the specified
activities and ensure that NMFS can
make the findings necessary for
issuance of an Authorization. Further,
the take estimation and negligible
impact determinations in this
Authorization do not rely on a
presumption of mitigation effectiveness.
Take estimates were based on modeling
efforts and were not reduced due to
mitigation measures.
Monitoring also includes vessel-based
observers for marine species up to 30
minutes prior to deploying live
munitions in the area. Eglin AFB has
submitted annual reports to NMFS
every year that describes all activities
that occur in the EGTTR. In addition,
Eglin AFB submitted annual reports to
NMFS at the conclusion of the Maritime
Strike Operations These missions are
similar in nature to the maritime WSEP
operations and the Eglin AFB provided
information on sighting information and
results from post-mission survey
observations. Based on those results,
NMFS determined that the mitigation
measures ensured the least practicable
adverse impact to marine mammals.
There were no observations of injured
marine mammals and no reports of
marine mammal mortality during the
Maritime Strike Operation activities.
The measures for the Maritime WSEP
are similar, except they will include
larger survey areas based on updated
acoustic analysis and previous
discussions with the MMC and NMFS.
Eglin AFB will continue to research
the feasibility of supplementing existing
monitoring efforts with passive acoustic
monitoring devices for future missions,
and has recently requested funding to
do so. However, even if this funding
request is approved, the funds will not
be available to implement the additional
measures for this Authorization. If
funding is approved, passive acoustic
monitoring will be included in future
missions that may be part of the
proposed rule to cover multiple
activities in the EGTTR.
Concerned Citizen Comment 1: The
private citizen commented that the U.S.
10751
Air Force should ‘‘bomb dead areas like
the Gulf of Mexico where no life can
live anyway’’, and expressed opposition
to the U.S. Air Force proposed Maritime
WSEP activities out of concern that
endangered animals would be harmed.
Response: As noted in the Federal
Register on November 21, 2016 (81 FR
83209), the Maritime WSEP activities
will take place in the Gulf of Mexico. In
addition, due to the location of the
activities, no threatened or endangered
species are anticipated to be taken and
NMFS has not authorized any take of
threatened or endangered species.
Finally, the information presented in
the notice for the proposed
Authorization (81 FR 83209; November
21, 2016) indicates that modeling results
show zero takes for mortality, and three
takes by Level A harassment. We make
a correction: Table 9 of the proposed
Authorization indicated these three
Level A takes were for permanent
threshold shift (PTS) only. However, the
correct estimate includes three PTS
takes and one slight lung injury take.
However, NMFS does not believe that
serious injury will result from this
activity and that therefore it is not
necessary to issue regulations through
section 101(a)(5)(A) of the MMPA,
rather, an IHA is appropriate.

2 ESA:
An additional 19 cetacean species
could occur within the northeastern
Gulf of Mexico, mainly occurring at or
beyond the shelf break (i.e., water depth
of approximately 200 m (656.2 ft))
located beyond the W–151A test area.
NMFS and Eglin AFB consider these 19
species to be rare or extralimital within
the W–151A test location area. These
species are the Bryde’s whale
(Balaenoptera edeni), sperm whale
(Physeter macrocephalus), dwarf sperm
whale (Kogia sima), pygmy sperm whale
(K. breviceps), pantropical spotted
dolphin (Stenella attenuata), Clymene
dolphin (S. clymene), spinner dolphin
(S. longirostris), striped dolphin (S.
coeruleoalba), Blainville’s beaked whale
(Mesoplodon densirostris), Gervais’
beaked whale (M. europaeus), Cuvier’s
beaked whale (Ziphius cavirostris),
killer whale (Orcinus orca), false killer
whale (Pseudorca crassidens), pygmy
killer whale (Feresa attenuata), Risso’s
dolphin (Grampus griseus), Fraser’s
dolphin (Lagenodelphis hosei), melonheaded whale (Peponocephala electra),
rough-toothed dolphin (Steno
bredanensis), and short-finned pilot
whale (Globicephala macrorhynchus).
Of these species, only the sperm
whale is listed as endangered under the
Endangered Species Act (ESA) and as
depleted throughout its range under the
MMPA. Sperm whale occurrence within
W–151A is unlikely because almost all
reported sightings have occurred in
water depths greater than 200 m (656.2
ft).
Because these species are unlikely to
occur within the W–151A area, Eglin
AFB has not requested and we are not
proposing to authorize take for them.
Thus, we do not consider these species
further in this notice.
We have reviewed Eglin AFB’s
species descriptions, including life
history information, distribution,
regional distribution, diving behavior,
and acoustics and hearing, for accuracy
and completeness. That information is
contained in sections 3 and 4 of Eglin
AFB’s 2016 Authorization application
and in Chapter 3 of Eglin AFB’s
Environmental Assessment (EA) and we
incorporate those sections by reference

rather than reprinting the information
here.
Other Marine Mammals in the Action
Area
The endangered West Indian manatee
(Trichechus manatus) rarely occurs in
the area (USAF 2014). The U.S. Fish and
Wildlife Service has jurisdiction over
the manatee; therefore, we did not
include an Authorization to harass
manatees and do not discuss this
species further in this notice.
Potential Effects of the Specified
Activity on Marine Mammals and Their
Habitat
This section of the notice of the
proposed Authorization (81 FR 83209,
November 21, 2016) included a
summary and discussion of the ways
that components (e.g., exposure to
impulsive noise and pressure waves
generated by live ordnance detonation
at or near the surface of the water) of the
specified activity, including mitigation,
may impact marine mammals and their
habitat. The ‘‘Estimated Take by
Incidental Harassment’’ section later in
this document will include a
quantitative analysis of the number of
individuals that we expect Eglin AFB to
take during this activity. The
‘‘Negligible Impact Analysis’’ section
will include the analysis of how this
specific activity will impact marine
mammals. We will consider the content
of the following sections: ‘‘Estimated
Take by Incidental Harassment’’ and
‘‘Mitigation’’ to draw conclusions
regarding the likely impacts of these
activities on the reproductive success or
survivorship of individuals—and from
that consideration—the likely impacts
of this activity on the affected marine
mammal populations or stocks.
In summary, the Maritime WSEP
training exercises under this
Authorization have the potential to take
marine mammals by exposing them to
impulsive noise and pressure waves
generated by live ordnance detonation
at or near the surface of the water.
Exposure to energy or pressure resulting
from these detonations could result in
Level A harassment (PTS and slight
PO 00000
Frm 00019
Fmt 4703
Sfmt 4703
lung injury) and by Level B harassment
(temporary threshold shift (TTS) and
behavioral harassment). In addition,
NMFS also considered the potential for
harassment from vessel operations.
The potential effects of impulsive
sound sources (underwater detonations)
from the training activities may include
one or more of the following: Tolerance,
masking, disturbance, hearing threshold
shift, stress response, and mortality.
NMFS provided detailed information on
these potential effects in the notice of
the proposed Authorization (81 FR
83209; November 21, 2016). The
information presented in that notice has
not changed.
Anticipated Effects on Habitat
Detonations of live ordnance will
result in temporary changes to the water
environment. Munitions could hit the
targets and not explode in the water.
However, because the targets are located
over the water, in water explosions
could occur. An underwater explosion
from these weapons could send a shock
wave and blast noise through the water,
release gaseous by-products, create an
oscillating bubble, and cause a plume of
water to shoot up from the water
surface. However, these effects will be
temporary and not expected to last more
than a few seconds.
Similarly, Eglin AFB does not expect
any long-term impacts with regard to
hazardous constituents to occur. Eglin
AFB considered the introduction of fuel,
debris, ordnance, and chemical
materials into the water column within
its EA and determined the potential
effects of each to be insignificant. NMFS
provided a summary of the analyses in
the notice for the proposed
Authorization (81 FR 83209; November
21, 2016). The information presented in
that notice has not changed.
Mitigation
In order to issue an Authorization
under section 101(a)(5)(D) of the
MMPA, NMFS must set forth the
permissible methods of taking pursuant
to such activity, and other means of
effecting the least practicable adverse
impact on such species or stock and its
E:\FR\FM\15FEN1.SGM
15FEN1
10753
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
habitat, paying particular attention to
rookeries, mating grounds, and areas of
similar significance, and the availability
of such species or stock for taking for
certain subsistence uses (where
relevant).
The NDAA of 2004 amended the
MMPA as it relates to military-readiness
activities and the incidental take
authorization process such that ‘‘least
practicable adverse impact’’ shall
include consideration of personnel
safety, practicality of implementation,
and impact on the effectiveness of the
military readiness activity.
NMFS and Eglin AFB worked to
identify potential practicable and
effective mitigation measures, which
include a careful balancing of the likely
benefit of any particular measure to the
marine mammals with the likely effect
of that measure on personnel safety,
practicality of implementation, and
impact on the ‘‘military-readiness
activity.’’ We refer the reader to section
11 of Eglin AFB’s application for more
detailed information on mitigation
measures which include the following:
Vessel-Based Monitoring
Eglin AFB will station a large number
of range clearing boats (approximately
30 to 35) around the test site to prevent
non-participating vessels from entering
the human safety zone. Based on the
composite footprint, range clearing
boats will be located approximately
15.28 km (9.5 mi) from the detonation
point (see Figure 11–1 in Eglin AFB’s
application). However, the actual
requested mission-day scenarios in
order to be able to model accumulated
energy. Therefore, each mission-day
scenario is considered a separate event
to model takes as opposed to modeling
for each live detonation. Eglin AFB
developed three mission-day categories
(Category A, which represents levels of
activities considered a worst-case
scenario consisting of ordnances with
large explosive weights as well as
surface and subsurface detonations;
Category B, which represents a ‘typical’
mission day based on levels of weapons
releases during past Maritime WSEP
activities; and Category C, which
represents munitions with smaller
explosive weights and surface
detonations only), and estimated the
number of days each category will be
executed during the 2017 Maritime
WSEP missions (See Table 1–3 in Eglin
AFB’s application for the Mission Day
Scenarios). Table 4 below provides the
categorization of mission days (Table 1–
3 in Eglin AFB’s application), and Table
5 provides the maximum range of effects
for all criteria and thresholds for
mission-day Categories A, B, and C.
These ranges were calculated based on
explosive acoustic characteristics,
sound propagation, and sound
transmission loss in the study area
(which incorporates water depth,
sediment type, wind speed, bathymetry,
and temperature/salinity profiles). Refer
to Appendix A of Eglin AFB’s
application for a complete description
of the acoustic modeling methodology
used in the analysis.
distance will vary based on the size of
the munition being deployed.
Trained protected species observers
(PSO) will be aboard five of these boats
and will conduct protected species
surveys before and after each test. The
protected species survey vessels will be
dedicated solely to observing for marine
species during the pre-mission surveys
while the remaining safety boats clear
the area of non-authorized vessels. The
protected species survey vessels will
begin surveying the area at sunrise. The
area to be surveyed will encompass the
zone of influence (ZOI), which is
discussed in more detail below.
Because of human safety issues, PSOs
will be required to leave the test area at
least 30 minutes in advance of live
weapon deployment and move to a
position on the safety zone periphery,
approximately 15.28 km (9.5 mi) from
the detonation point. PSOs will
continue to scan for marine mammals
from the periphery. Animals that may
enter the area after Eglin AFB has
completed the pre-mission surveys and
prior to detonation will not reach the
predicted smaller slight lung injury and/
or mortality zones due to their swim
speed and the size of the clearance zone.
Determination of the Zone of Influence
Historically, Eglin AFB has
conservatively used the number of live
weapons deployed to estimate take of
marine mammals. This method assumed
a fresh population of marine mammals
for each detonation to calculate the
number taken. However, NMFS

Mortality and slight lung injury
threshold ranges would extend from 47
to 216 m and 84 to 595 m, respectively,
depending on the mission-day category.
These ranges would fall within the
Level A harassment ranges. Based on
the planned activities on a given
mission day, and the ranges presented
in Table 5, Eglin AFB will ensure that
the area equating to the Level A
harassment threshold range is free of
protected species. By clearing the Level
A harassment threshold range of
protected species, animals that may
enter the area after the completed premission surveys but prior to detonation
would not reach the smaller slight lung
injury or mortality zones as explained
above. Because of human safety issues,
Eglin AFB will require PSOs to leave the
test area at least 30 minutes in advance
of live weapon deployment and move to
a position on the safety zone periphery,
approximately 15 km (9.5 mi) from the
detonation point. PSOs will continue to
scan for marine mammals from the
periphery, but effectiveness will be
limited as the boat will remain at a
designated station.
Video Monitoring: In addition to
vessel-based monitoring, Eglin AFB will
position three high-definition video
cameras on the GRATV anchored onsite, as described earlier, to allow for
real-time monitoring for the duration of
the mission. The camera configuration
and actual number of cameras used will
depend on specific mission
requirements. In addition to monitoring
the area for mission objective issues, the
camera(s) will also monitor for the
presence of protected species. A trained
marine species observer from Eglin
Natural Resources will be located in
Eglin AFB’s Central Control Facility,
along with mission personnel, to view
the video feed before and during test
activities. The distance to which objects
can be detected at the water surface by
use of the cameras is considered
generally comparable to that of the
human eye.
The GRATV will be located about 183
m (600 ft) from the target. The mortality
threshold ranges correspond to the
modified Goertner model adjusted for
the weight of an Atlantic spotted
dolphin calf, and extend from 0 to 216
VerDate Sep<11>2014
18:44 Feb 14, 2017
Jkt 241001
286
m (0 to 709 ft) from the target,
depending on the ordnance, and the
Level A ranges for both common
bottlenose and Atlantic spotted
dolphins extend up to 945 m (3,100 ft)
from the target, depending on the
ordnance and harassment criterion.
Given these distances, observers can
reasonably be expected to view a
substantial portion of the mortality zone
in front of the camera, although a small
portion would be behind or to the side
of the camera view. Based on previous
monitoring reports for this activity, the
pre-training surveys for delphinids and
other protected species within the
mission area are effective. PSOs can
view some portion of the Level A
harassment zone, although the view
window will be less than that of the
mortality zone (a large percentage will
be behind or to the side of the camera
view).
In addition to the two types of visual
monitoring discussed earlier in this
section, Eglin AFB personnel will be
present within the mission area (on
boats and on the GRATV) on each day
of testing well in advance of weapon
deployment, typically near sunrise.
They will perform a variety of tasks
including target preparation, equipment
checks, etc., and will opportunistically
observe for marine mammals and
indicators as feasible throughout test
preparation. However, we consider
these observations as supplemental to
the mitigation and monitoring and will
only occur as time and schedule
permits. Eglin AFB personnel will relay
information on these types of sightings
to the Lead Biologist, as described in the
following mitigation sections.
Pre-Mission Monitoring
The purposes of pre-mission
monitoring are to: (1) Evaluate the
mission site for environmental
suitability, and (2) verify that the ZOI is
free of visually detectable marine
mammals, as well as potential
indicators of these species. On the
morning of the mission, the Test
Director and Safety Officer will confirm
that there are no issues that will
preclude mission execution and that
weather is adequate to support
mitigation measures.

Sunrise or Two Hours Prior to Mission
Eglin AFB range clearing vessels and
protected species survey vessels will be
on site at least two hours prior to the
mission. The Lead Biologist on board
one survey vessel will assess the overall
suitability of the mission site based on
environmental conditions (sea state) and
presence/absence of marine mammal
indicators. Eglin AFB personnel will
communicate this information to Tower
Control and personnel will relay the
information to the Safety Officer in
Central Control Facility.
One and One-Half Hours Prior to
Mission
Vessel-based surveys will begin
approximately one and one-half hours
prior to live weapons deployment.
Surface vessel PSOs will survey the ZOI
and relay all marine species and
indicator sightings, including the time
of sighting, GPS location, and direction
of travel, if known, to the Lead
Biologist. The Lead Biologist will
document all sighting information on
report forms that he/she will submit to
Eglin Natural Resources after each
mission. Surveys will continue for
approximately one hour. During this
time, Eglin AFB personnel in the
mission area will also observe for
marine species as feasible. If marine
mammals or indicators are observed
within the ZOI for that day’s mission
activities, the range will be declared
‘‘fouled,’’ a term that signifies to
mission personnel that conditions are
such that a live ordnance drop cannot
occur (e.g., protected species or civilian
vessels are in the mission area). If there
are no observations of marine mammals
or indicators of marine mammals, Eglin
AFB will declare the range clear of
protected species.
One-Half Hour Prior to Mission
At approximately 30 minutes prior to
live weapon deployment, marine
species PSOs will be instructed to leave
the mission site and remain outside the
safety zone, which on average will be
15.28 km (9.5 mi) from the detonation
point. The actual size is determined by
weapon net explosive weight and
method of delivery. The survey team
will continue to monitor for protected
E:\FR\FM\15FEN1.SGM
15FEN1
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
species while leaving the area. As the
survey vessels leave the area, marine
species monitoring of the immediate
target areas will continue at the Central
Control Facility through the live video
feed received from the high definition
cameras on the GRATV. Once the
survey vessels have arrived at the
perimeter of the safety zone
(approximately 30 minutes after leaving
the area per instructions from Eglin
AFB, depending on actual travel time),
Eglin AFB will declare the range as
‘‘green’’ and the mission will proceed,
assuming all non-participating vessels
have left the safety zone as well.
mstockstill on DSK3G9T082PROD with NOTICES
Execution of Mission
Immediately prior to live weapons
drop, the Test Director and Safety
Officer will communicate to confirm the
results of marine mammal surveys and
the appropriateness of proceeding with
the mission. The Safety Officer will
have final authority to proceed with,
postpone, or cancel the mission. Eglin
AFB will postpone the mission if:
• Any of the high-definition video
cameras are not operational for any
reason;
• Any marine mammal is visually
detected within the ZOI. Postponement
will continue until the animal(s) that
caused the postponement is: (1)
Confirmed to be outside of the ZOI and
heading away from the targets; or (2) not
seen again for 30 minutes and presumed
to be outside the ZOI due to the animal
swimming out of the range;
• Any large schools of fish or large
flocks of birds feeding at the surface are
within the ZOI. Postponement will
continue until Eglin AFB personnel
confirm that these potential indicators
are outside the ZOI:
• Any technical or mechanical issues
related to the aircraft or target boats; or
• Any non-participating vessel enters
the human safety zone prior to weapon
release.
In the event of a postponement,
protected species monitoring will
continue from the Central Control
Facility through the live video feed.
Observers will also continue to monitor
from the vessels at the safety perimeter,
with limited effectiveness due to the
distance from the detonation site.
Post-Mission Monitoring
Post-mission monitoring determines
the effectiveness of pre-mission
mitigation by reporting sightings of any
marine mammals. Post-detonation
monitoring surveys will commence once
the mission has ended or, if required, as
soon as personnel declare the mission
area safe. Vessels will move into the
survey area from outside the safety zone
VerDate Sep<11>2014
18:44 Feb 14, 2017
Jkt 241001
and monitor for at least 30 minutes,
concentrating on the area down-current
of the test site. This area is easily
identifiable because of the floating
debris in the water from impacted
targets. Up to 10 Eglin AFB support
vessels will be cleaning debris and
collecting damaged targets from this
area thus spending several hours in the
area once Eglin AFB completes the
mission. PSOs will document and report
any marine mammal species, number,
location, and behavior of any animals
observed to Eglin Natural Resources.
Mission Delays Due to Weather
Eglin AFB will delay or reschedule
Maritime WSEP missions if the Beaufort
sea state is greater than number 4 at the
time of the testing activities. The Lead
Biologist aboard one of the survey
vessels will make the final
determination of whether conditions are
conducive for sighting protected species
or not.
We have carefully evaluated Eglin
AFB’s mitigation measures in the
context of ensuring that we prescribe
the means of effecting the least
practicable impact on the affected
marine mammal species and stocks and
their habitat. Our evaluation of potential
measures included consideration of the
following factors in relation to one
another:
• The manner in which, and the
degree to which, the successful
implementation of the measure is
expected to minimize adverse impacts;
• The proven or likely efficacy of the
specific measure to minimize adverse
impacts as planned; and
• The practicability of the measure
for applicant implementation.
Any mitigation measure(s) prescribed
by NMFS should be able to accomplish,
have a reasonable likelihood of
accomplishing (based on current
science), or contribute to the
accomplishment of one or more of the
general goals listed here:
1. Avoidance or minimization of
injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may
contribute to this goal);
2. A reduction in the numbers of
marine mammals (total number or
number at biologically important times
or locations) exposed to stimuli
expected to result in incidental take
(this goal may contribute to 1, above, or
to reducing takes by behavioral
harassment only);
3. A reduction in the number of times
(total number or number at biologically
important times or locations)
individuals will be exposed to stimuli
that we expect to result in the take of
marine mammals (this goal may
PO 00000
Frm 00022

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 times
or locations) to training exercises that
we expect 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; and
6. For monitoring directly related to
mitigation—an increase in the
probability of detecting marine
mammals, thus allowing for more
effective implementation of the
mitigation.
Based on our evaluation of Eglin
AFB’s mitigation measures, as well as
other measures that may be relevant to
the specified activity, we have
determined that the mitigation measures
provide the means of effecting the least
practicable impact on marine mammal
species or stocks and their habitat,
paying particular attention to rookeries,
mating grounds, and areas of similar
significance (while also considering
personnel safety, practicality of
implementation, and the impact of
effectiveness of the military readiness
activity).
Monitoring and Reporting
In order to issue an Authorization for
an activity, section 101(a)(5)(D) of the
MMPA states that we must set forth
‘‘requirements pertaining to the
monitoring and reporting of such
taking.’’ The MMPA implementing
regulations at 50 CFR 216.104(a)(13)
indicate that requests for an
authorization must include the
suggested means of accomplishing the
necessary monitoring and reporting that
will result in increased knowledge of
the species and our expectations of the
level of taking or impacts on
populations of marine mammals present
in the action area.
Eglin AFB submitted a marine
mammal monitoring plan in their
Authorization application. NMFS has
not modified or supplemented the plan
based on comments or new information
received from the public during the
public comment period. Any monitoring
requirement we prescribe should
improve our understanding of one or
more of the following:

The Authorization for Maritime WSEP
operations will require the following
measures:
(1) Eglin AFB will track the use of the
EGTTR for test firing missions and
protected species observations through
the use of mission reporting forms;
(2) Eglin AFB will submit a summary
report of marine mammal observations
and Maritime WSEP activities to the
NMFS Southeast Regional Office (SERO)
and the Office of Protected Resources 90
days after expiration of the current
Authorization. This report must include
the following information: (i) Date and
time of each Maritime WSEP exercise;
(ii) a complete description of the preexercise and post-exercise activities
related to mitigating and monitoring the
effects of Maritime WSEP exercises on
marine mammal populations; and (iii)
results of the Maritime WSEP exercise
monitoring, including number of marine
mammals (by species) that may have
been harassed due to presence within
the activity zone;
(3) Eglin AFB will monitor for marine
mammals in the action area. If Eglin
AFB personnel observe or detect any
dead or injured marine mammals prior
to testing, or detects any injured or dead
marine mammals during live fire
exercises, Eglin AFB must cease
operations and submit a report to NMFS
within 24 hours; and
(4) Eglin AFB must immediately
report any unauthorized takes of marine
mammals (i.e., serious injury or
mortality) to NMFS and to the
respective Southeast Region stranding

Monitoring Results From Previously
Authorized Activities
Eglin AFB complied with the
mitigation and monitoring required
under the previous Authorization for
2016 Maritime WSEP activities. Marine
mammal monitoring occurred before,
during, and after each Maritime WSEP
mission. During the course of these
activities, Eglin AFB’s monitoring
reports showed that they did not exceed
the take levels authorized. In
accordance with the 2015
Authorization, Eglin AFB submitted a
monitoring report (available at:
www.nmfs.noaa.gov/pr/permits/
incidental/military.htm).
Under the 2016 Authorization, Eglin
AFB anticipated conducting Maritime
WSEP training missions over
approximately two to three weeks, but
actually conducted a total of five
mission days (February 11 and March
14–17) associated with live ordnance
delivery. Due to weather conditions and
high sea states, no live missions were
conducted February 8–10. Munitions
that were actually dropped accounted
for only approximately 41 percent of
what was authorized in the 2016
Authorization.
During the February 2016 mission,
Eglin AFB released one AGM–65
Maverick. The AGM–65 Maverick is a
penetrating blast-fragment warhead that
detonates at the surface and has 86 lb
NEW. Eglin AFB conducted the required
monitoring for marine mammals or
indicators of marine mammals (e.g.,
flocks of birds, baitfish schools, or large
fish schools) before, during, and after
each mission and observed a mixture of
six bottlenose and spotted dolphins
approximately seven miles outside of
the largest ZOI, so no action was
required. No protected species were
observed within the ZOI during premission surveys, mission activities, or
during post-mission surveys. Therefore,
the mission resulted in no acoustic
impacts to marine mammals.
During the March 2016 live fire
missions, Eglin AFB expended two
AGM–65 Mavericks and twelve AGM–
114 Hellfire missiles. The NEW of the
munitions that detonated at the water
surface or up to 3 m (10 ft) below the
surface are 86 lb for the AGM–65
Maverick missiles and 13 lb for the
AGM–114 Hellfire missiles. Eglin AFB
conducted the required monitoring for
marine mammals or indicators of
marine mammals (e.g., flocks of birds,
baitfish schools, or large fish schools)
before, during, and after each mission

and observed two species of marine
mammals: The common bottlenose
dolphin and Atlantic spotted dolphin;
one sea turtle; and two flocks of
approximately 10–20 birds on two
separate occasions (upon investigation
there was no evidence of protected
species associated with either flock of
birds). Eglin AFB confirmed that all
protected species observed were outside
of the ZOI at the conclusion of each premission survey.
After each mission, Eglin AFB reentered the ZOI to begin post-mission
surveys for marine mammals and debris
clean-up operations. Eglin AFB
personnel did not observe reactions
indicative of disturbance during the premission surveys and did not observe
any marine mammals during the postmission surveys. In summary, Eglin
AFB reports that no observable
instances of take of marine mammals
occurred incidental to the Maritime
WSEP training activities under the 2016
Authorization.
Estimated Numbers of Marine
Mammals Taken by Harassment
This section includes an estimate of
the number of incidental ‘‘takes’’
proposed for authorization pursuant to
this Authorization, which will inform
both NMFS negligible impact
determination. Harassment is the means
of take expected to result from these
activities, and the definition of
harassment as it applies to a ‘‘military
readiness activity’’ is: (i) Any act that
injures or has the significant potential to
injure a marine mammal or marine
mammal stock in the wild (Level A
Harassment); or (ii) any act that disturbs
or is likely to disturb a marine mammal
or marine mammal stock in the wild by
causing disruption of natural behavioral
patterns, including, but not limited to,
migration, surfacing, nursing, breeding,
feeding, or sheltering, to a point where
such behavioral patterns are abandoned
or significantly altered (Level B
Harassment).
NMFS’ analysis identified the
physiological responses and behavioral
responses that could potentially result
from exposure to underwater explosive
detonations. In this section, we will
relate the potential effects to marine
mammals from underwater detonation
of explosives to the MMPA regulatory
definitions of Level A and Level B
harassment. This section will also
quantify the effects that might occur
from the military readiness activities in
W–151.
At NMFS’ recommendation, Eglin
AFB updated the thresholds used for
onset of TTS (Level B Harassment) and
onset of PTS (Level A Harassment) to be
E:\FR\FM\15FEN1.SGM

10757
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
Of the potential effects described
earlier in this document, the following
are the types of effects that fall into the
Level B harassment category:
Behavioral Harassment
Behavioral disturbance that rises to
the level described in the above
definition, when resulting from
harassment, not Level A harassment
(injury).
Acoustic Thresholds
As discussed previously, TTS can
affect how an animal behaves in
response to the environment, including
conspecifics, predators, and prey. NMFS
classifies TTS (when resulting from
exposure to explosives and other
impulsive sources) as Level B
Level B Harassment
exposures to non-impulsive or
impulsive sound, is Level B harassment.
Some of the lower level physiological
stress responses discussed earlier will
also likely co-occur with the predicted
harassments, although these responses
are more difficult to detect and fewer
data exist relating these responses to
specific received levels of sound. When
predicting Level B harassment based on
estimated behavioral responses, we are
aware that those takes may have a
stress-related physiological component.
Temporary Threshold Shift
consistent with the thresholds outlined
in NMFS’ August 2016 ‘‘Technical
Guidance for Assessing the Effects of
Anthropogenic Sound on Marine
Mammal Hearing’’ (NMFS 2016). NMFS
believes that the thresholds outlined in
the new Technical Guidance represent
the best available science. The report is
available on the internet at:
www.nmfs.noaa.gov/pr/acoustics/
Acoustic%20Guidance%20Files/opr55_acoustic_guidance_tech_memo.pdf.
Table 6 outlines the acoustic
thresholds for mid-frequency cetaceans
used by NMFS for this Authorization
when addressing noise impacts from
explosives. Both common bottlenose
dolphins and Atlantic spotted dolphins
are considered mid-frequency cetaceans.
Level A Harassment
Of the potential effects that were
described earlier, the following are the
types of effects that fall into the Level
A Harassment category:
Permanent Threshold Shift
PTS (resulting either from exposure to
explosive detonations) is irreversible
and NMFS considers this to be an
injury.

impact thresholds was calculated with a
two-dimensional approach using the
product of the adjusted impact area,
animal density, and annual number of
events for each mission-day category. A
take is considered to occur for sound
exposure level (SEL) metrics if the
received level is equal to or above the
associated threshold within the
appropriate frequency band of the
sound received, adjusted for the
appropriate weighting function value of
that frequency band. Similarly, a take
would occur for impulse and peak SPL
metrics if the received level is equal to
or above the associated threshold.
Density Estimation
Density estimates for bottlenose
dolphin and spotted dolphin were
obtained from Duke University Marine
Geospatial Ecology Lab Reports (Roberts
et al., 2016). Raster data from Duke
University were imported into ArcGIS
and overlaid onto the Maritime WSEP
mission area. Density values were
provided in 100 km2 boxes. A 30-km by
30-km (900 km2) area centered on the
Maritime WSEP mission location was
selected, which consisted of nine 100km2 blocks. Density values from those
blocks were averaged and converted to
number of animals per square kilometer
to obtain average annual density
estimates for the common bottlenose
and Atlantic spotted dolphins used in
this analysis (see Table 8 for the
resultant densities for these species).

ESTIMATES WITHIN EGLIN AFB’S
EGTTR
Take Estimation
Table 9 indicates the modeled
potential for lethality, injury, and noninjurious harassment (including
behavioral harassment) to marine
mammals in the absence of mitigation
measures. Eglin AFB and NMFS
estimate that approximately three
marine mammals could be exposed to
injurious Level A harassment noise
levels (187 dB SEL) and approximately
326 animals could be exposed to Level
B harassment (TTS and behavioral
harassment) noise levels in the absence
of mitigation measures.

Based on the mortality exposure
estimates calculated by the acoustic
model and the anticipated effectiveness
of mitigation measures, zero marine
mammals are expected to be affected by
pressure levels associated with
mortality or serious injury. Zero marine
mammals are expected to be exposed to
pressure levels associated with
gastrointestinal tract injury.
NMFS generally considers PTS to fall
under the injury category (Level A
Harassment). An animal would need to
stay very close to the sound source for
an extended amount of time to incur a
serious degree of PTS, which could
increase the probability of mortality. In
this case, it would be highly unlikely for
this scenario to unfold given the nature
of any anticipated acoustic exposures
that could potentially result from a
mobile marine mammal that NMFS
generally expects to exhibit avoidance
behavior to loud sounds within the
EGTTR. NMFS concludes that
possibility of minor PTS in the form of
slight upward shift of hearing threshold
at certain frequency bands by a few
individuals of marine mammals is low,
but not unlikely. The majority of the
incidental ‘takes’ resulting from Eglin
VerDate Sep<11>2014

Jkt 241001
AFB’s WSEP activities will consist of
Level B harassment, such as TTS and
behavioral responses.
Negligible Impact Analysis
Determinations
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’’ (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, we consider other factors,
such as the likely nature of any
responses (e.g., intensity, duration), the
context of any responses (e.g., critical
reproductive time or location,
migration), as well as the number and
nature of estimated Level A harassment
takes, the number of estimated
mortalities, and effects on habitat.
Consistent with the 1989 preamble for
PO 00000
Frm 00025
Fmt 4703
Sfmt 4703
NMFS’ implementing regulations (54 FR
40338; September 29, 1989), the impacts
from other past and ongoing
anthropogenic activities are
incorporated into these analyses via
their impacts on the environmental
baseline (e.g., as reflected in the
regulatory status of the species,
populations size, growth rate where
known, ongoing sources of humancaused mortality, or ambient noise
levels).
To avoid repetition, the discussion
below applies to each of the species for
which we authorize incidental take for
Eglin AFB’s activities, given that
expected impacts are expected to be the
same for both species.
In making a negligible impact
determination, we consider:
• The number of anticipated injuries,
serious injuries, or mortalities;
• The number, nature, and intensity,
and duration of Level B harassment;
• The context in which the takes
occur (e.g., impacts to areas of
significance, impacts to local
populations, and cumulative impacts
when taking into account successive/
contemporaneous actions when added
to baseline data);
E:\FR\FM\15FEN1.SGM
15FEN1
mstockstill on DSK3G9T082PROD with NOTICES
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
• The status of stock or species of
marine mammals (i.e., depleted, not
depleted, decreasing, increasing, stable,
impact relative to the size of the
population);
• Impacts on habitat affecting rates of
recruitment/survival; and
• The effectiveness of monitoring and
mitigation measures to reduce the
number or severity of incidental take.
For reasons stated previously in this
document and based on the following
factors, Eglin AFB’s specified activities
are not likely to cause long-term
behavioral disturbance, serious injury,
or death.
The takes from Level B harassment
will be due to potential behavioral
disturbance and TTS. The takes from
Level A harassment will be due to some,
likely lesser, degree of PTS and slight
lung injury. Activities will only occur
over a timeframe of two to three weeks
beginning in February 2017, with one or
two missions occurring per day. It is
possible that some individuals may be
taken more than once if those
individuals are located in the exercise
area on two different days when
exercises are occurring.
Noise-induced threshold shifts (TS,
which includes PTS) are defined as
increases in the threshold of audibility
(i.e., the sound has to be louder to be
detected) of the ear at a certain
frequency or range of frequencies (ANSI
1995; Yost 2000). Several important
factors relate to the magnitude of TS,
such as level, duration, spectral content
(frequency range), and temporal pattern
(continuous, intermittent) of exposure
(Yost 2000; Henderson et al., 2008). TS
occurs in terms of frequency range (Hz
or kHz), hearing threshold level (dB), or
both frequency and hearing threshold
level (CDC 2004).
In addition, there are different degrees
of PTS ranging from slight/mild to
moderate and from severe to profound
(Clark 1981). Profound PTS or the
complete loss of the ability to hear in
one or both ears is commonly referred
to as deafness (CDC 2004; WHO 2006).
High-frequency PTS, presumably as a
normal process of aging that occurs in
humans and other terrestrial mammals,
has also been demonstrated in captive
cetaceans (Ridgway and Carder 1997;
Yuen et al., 2005; Finneran et al., 2005;
Houser and Finneran 2006; Finneran et
al., 2007; Schlundt et al., 2011) and in
stranded individuals (Mann et al.,
2010).
In terms of what is analyzed for the
potential PTS (Level A harassment) in
marine mammals as a result of Eglin
AFB’s Maritime WSEP operations, if it
occurs, NMFS has determined that the
levels will be slight/mild because most
VerDate Sep<11>2014
18:44 Feb 14, 2017
Jkt 241001
cetaceans would be expected to show
relatively high levels of avoidance.
Further, it is uncommon to sight marine
mammals within the target area,
especially for prolonged durations.
Results from monitoring programs
associated other Eglin AFB activities
and for Eglin AFB’s 2016 Maritime
WSEP activities have shown the absence
of marine mammals within the EGTTR
during and after maritime operations.
Avoidance varies among individuals
and depends on their activities or
reasons for being in the area.
NMFS’ predicted estimates for Level
A harassment take are likely
overestimates of the likely injury that
will occur. NMFS expects that
successful implementation of the
required vessel-based and video-based
mitigation measures will avoid Level A
take in some instances. Also, NMFS
expects that some individuals will avoid
the source at levels expected to result in
injury. Nonetheless, although NMFS
expects that Level A harassment is
unlikely to occur at the numbers
authorized, because it is difficult to
quantify the degree to which the
mitigation and avoidance will reduce
the number of animals that might incur
PTS, we are authorizing the modeled
number of Level A takes (three), which
does not take mitigation or avoidance
into consideration. However, we
anticipate that any PTS incurred
because of mitigation and the likely
short duration of exposures, will be in
the form of only a small degree of PTS
and not total deafness.
While animals may be impacted in
the immediate vicinity of the activity,
because of the short duration of the
actual individual explosions themselves
(versus continual sound source
operation) combined with the short
duration of the Maritime WSEP
operations, NMFS has determined that
there will not be a substantial impact on
marine mammals or on the normal
functioning of the nearshore or offshore
Gulf of Mexico ecosystems. We do not
expect that the activity will impact rates
of recruitment or survival of marine
mammals since, among other factors
listed below, we do not expect mortality
(which would remove individuals from
the population) or serious injury to
occur. In addition, the activity will not
occur in areas (and/or times) of
significance for the marine mammal
populations potentially affected by the
exercises (e.g., feeding, resting, or
reproductive areas), and the activities
will only occur in a small part of their
overall range, so the impact of any
potential temporary displacement will
be negligible and animals are expected
to return to the area after the cessation
PO 00000
Frm 00026
Fmt 4703
Sfmt 4703
10759
of activities. Although the activity could
result in Level A (PTS or slight lung
injury, not gastrointestinal tract injury)
and Level B (behavioral disturbance and
TTS of lesser degree and shorter
duration) harassment of marine
mammals, the level of harassment is not
anticipated to impact rates of
recruitment or survival of marine
mammals because the number of
exposed animals is expected to be low
due to the short-term (i.e., four hours a
day or less) and site-specific nature of
the activity. We do not anticipate that
the effects will be detrimental to rates of
recruitment and survival because we do
not expect serious extended behavioral
responses that would result in energetic
effects at the level to impact fitness.
Moreover, the mitigation and
monitoring measures for the
Authorization (described earlier in this
document) are expected to further
minimize the potential for harassment.
The protected species surveys will
require Eglin AFB to search the area for
marine mammals, and if any are found
in the live fire area, then the exercise
will be suspended until the animal(s)
has left the area. Moreover, marine
species observers located in the Eglin
control tower will monitor the highdefinition video feed from cameras
located on the instrument barge
anchored on-site for the presence of
protected species. Furthermore,
Maritime WSEP missions will be
delayed or rescheduled if the sea state
is greater than a 4 on the Beaufort Scale
at the time of the test. In addition,
Maritime WSEP missions will occur no
earlier than two hours after sunrise and
no later than two hours prior to sunset
to ensure adequate daylight for pre- and
post-mission monitoring.
Based on the analysis contained
herein of the likely effects of the
specified activity on marine mammals
and their habitat, and taking into
consideration the implementation of the
mitigation and monitoring measures,
NMFS finds that Eglin AFB’s Maritime
WSEP operations will result in the
incidental take of marine mammals, by
Level A and Level B harassment, but
that the taking from the Maritime WSEP
exercises will not have an adverse effect
on annual rates of recruitment or
survival, and therefore will have a
negligible impact on the affected species
or stocks.
Impact on Availability of Affected
Species or Stock for Taking for
Subsistence Uses
There are no relevant subsistence uses
of marine mammals implicated by this
action. Therefore, NMFS has
determined that the total taking of
E:\FR\FM\15FEN1.SGM
15FEN1
10760
Federal Register / Vol. 82, No. 30 / Wednesday, February 15, 2017 / Notices
affected species or stocks will not have
an unmitigable adverse impact on the
availability of such species or stocks for
taking for subsistence purposes.
Endangered Species Act (ESA)
Due to the location of the activity and
past experience with similar
authorizations for these activities, no
ESA-listed marine mammal species are
likely to be affected. Therefore, NMFS
has determined that this Authorization
will have no effect on ESA-listed
species and has determined that a
section 7 consultation under the ESA is
not required for the issuance of an
MMPA Authorization to Eglin AFB.

impacts of the specified activities on
marine mammals. NMFS, after review
and evaluation of the Eglin AFB EA for
consistency with the regulations
published by the Council of
Environmental Quality (CEQ) and
NOAA Administrative Order 216–6,
Environmental Review Procedures for
Implementing the National
Environmental Policy Act, adopted the
EA. After considering the EA, the
information in the 2014 Authorization
application, and the Federal Register
notice, as well as public comments,
NMFS’ issuance of the 2015
Authorization and determination that
the activity was not likely to result in
significant impacts on the human
environment, NMFS adopted Eglin
AFB’s EA under 40 CFR 1506.3; and
issued a FONSI statement on issuance of
an Authorization under section
101(a)(5) of the MMPA.
In accordance with NOAA
Administrative Order 216–6
(Environmental Review Procedures for
Implementing the National
Environmental Policy Act, May 20,
1999), NMFS will again review the
information contained in Eglin AFB’s
EA and determine whether the EA
accurately and completely describes the
preferred action alternative and the
potential impacts on marine mammals.
Based on this review and analysis,
NMFS has reaffirmed 2015 FONSI
statement on issuance of an annual
authorization under section 101(a)(5) of
the MMPA.

Takes of Marine Mammals Incidental to Specified Activities;
Taking Marine Mammals Incidental to the U.S. Air Force Conducting
Maritime Weapon Systems Evaluation Program Operational Testing Within
the Eglin Gulf Test and Training Range
AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA), Commerce.
ACTION: Notice; issuance of an incidental harassment authorization.
-----------------------------------------------------------------------
SUMMARY: In accordance with the Marine Mammal Protection Act (MMPA)
implementing regulations we (NMFS) hereby give notice that we have
issued an Incidental Harassment Authorization (IHA) to the U.S. Air
Force, Eglin Air Force Base (Eglin AFB), to take two species of marine
mammals, the Atlantic bottlenose dolphin (Tursiops truncatus) and
Atlantic spotted dolphin (Stenella frontalis), by harassment,
incidental to a Maritime Weapon Systems Evaluation Program (Maritime
WSEP) within the Eglin Gulf Test and Training Range (EGTTR) in the Gulf
of Mexico from February 4, 2017 through February 3, 2018. Eglin AFB's
activities are military readiness activities per the MMPA, as amended
by the National Defense Authorization Act (NDAA) for Fiscal Year 2004.
DATES: Effective February 4, 2017 through February 3, 2018.
ADDRESSES: An electronic copy of the final Authorization, Eglin AFB's
application and their final Environmental Assessment (EA) titled,
``Maritime Weapons System Evaluation Program'' are available by writing
to Ms. Jolie Harrison, Chief, Permits and Conservation Division, Office
of Protected Resources, National Marine Fisheries Service, 1315 East-
West Highway, Silver Spring, MD 20910; by telephoning the contacts
listed here at 301-427-8401, or by visiting the internet at: https://www.nmfs.noaa.gov/pr/permits/incidental/military.htm.
FOR FURTHER INFORMATION CONTACT: Mr. Dale Youngkin, Office of Protected
Resources, NMFS, (301) 427-8401.
SUPPLEMENTARY INFORMATION:
Background
Sections 101(a)(5)(A) and (D) of the Marine Mammal Protection Act
of 1972, as amended (MMPA; 16 U.S.C. 1361 et seq.) direct the Secretary
of Commerce to allow, upon request, the incidental, but not
intentional, taking of small numbers of marine mammals of a species or
population stock, by U.S. citizens who engage in a specified activity
(other than commercial fishing) within a specified geographical region
if, after NMFS provides a notice of a proposed authorization to the
public for review and comment and that NMFS makes certain findings.
An Authorization for incidental takings for marine mammals 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 taking
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.''
[[Page 10748]]
Where there is the potential for serious injury or death, the
allowance of incidental taking requires promulgation of regulations
under section 101(a)(5)(A). Subsequently, a Letter (or Letters) of
Authorization may be issued as governed by the prescriptions
established in such regulations, provided that the level of taking will
be consistent with the findings made for the total taking allowable
under the specific regulations. Under section 101(a)(5)(D), NMFS may
authorize incidental taking by harassment only (i.e., no serious injury
or mortality) for periods of not more than one year, pursuant to
requirements and conditions contained within an Incidental Harassment
Authorization (IHA). The promulgation of regulations or issuance of
IHAs (with their associated prescripted mitigation, monitoring, and
reporting) requires notice and opportunity for public comment.
The NDAA (Pub. L. 108-136) removed the ``small numbers'' and
``specified geographical region'' limitations indicated earlier and
amended the definition of harassment as it applies to a ``military
readiness activity'' to read as follows (section 3(18)(B) of the MMPA):
(i) Any act that injures or has the significant potential to injure a
marine mammal or marine mammal stock in the wild (Level A Harassment);
or (ii) any act that disturbs or is likely to disturb a marine mammal
or marine mammal stock in the wild by causing disruption of natural
behavioral patterns, including, but not limited to, migration,
surfacing, nursing, breeding, feeding, or sheltering, to a point where
such behavioral patterns are abandoned or significantly altered (Level
B Harassment).
Summary of Request
On February 4, 2016, we issued an Authorization to Eglin AFB to
take marine mammals, by harassment, incidental to a Maritime WSEP
within the EGTTR in the Gulf of Mexico from February 4, 2016 through
February 3, 2017 (see 81 FR 7307; February 11, 2016). These missions
were very similar to previous Maritime WSEP mission activities for
which incidental harassment authorizations were issued the previous
year (80 FR 17394; April 1, 2015). On September 19, 2016, we received a
renewal request for an Authorization from Eglin AFB to continue the
missions authorized in 2016. We considered the revised renewal request
as adequate and complete on September 27, 2016.
Due to the ongoing nature of these activities, as well as the fact
that other mission activities are conducted within the EGTTR, we have
discussed developing a rulemaking to encompass all mission activities
in the EGTTR, and anticipate that the Maritime WSEP activities will be
part of that future rulemaking. However, this Authorization is being
granted due to timing constraints to ensure that these activities are
in compliance with the MMPA while the future rulemaking is in process.
Eglin AFB will conduct Maritime WESP missions within the EGTTR
airspace over the Gulf of Mexico within Warning Area 151 (W-151),
specifically within sub-area W-151A (see Figure 2-1 of Eglin AFB's
application and Figure 1 below). The Maritime WSEP training activities
are planned to occur during daylight hours in February and March 2017,
however, the activities could occur between February 4, 2017, and
February 3, 2018.
Eglin AFB will use multiple types of live munitions (e.g., gunnery
rounds, rockets, missiles, and bombs) against small boat targets in the
EGTTR. These activities qualify as military readiness activities.
The following aspects of the Maritime WSEP training activities have
the potential to take marine mammals: Exposure to impulsive noise and
pressure waves generated by live ordnance detonation at or near the
surface of the water. Take, by Level B harassment, of individuals of
common bottlenose dolphin or Atlantic spotted dolphin could potentially
result from the specified activity. Additionally, although NMFS does
not expect it to occur, Eglin AFB has also requested authorization for
Level A harassment of up to four individuals of either common
bottlenose dolphins (2) or Atlantic spotted dolphins (1). Therefore,
Eglin AFB requested authorization to take individuals of two cetacean
species by Level A and Level B harassment.
Eglin AFB's Maritime WSEP training activities may potentially
impact marine mammals at or near the water surface in the absence of
mitigation. Marine mammals could potentially be harassed, injured, or
killed by exploding and non-exploding projectiles, and falling debris.
However, based on analyses provided in Eglin AFB's 2016 application,
Eglin AFB's previous applications and Authorizations, Eglin AFB's EA,
and past monitoring reports for the authorized activities conducted in
February and March 2016 and 2015, and for reasons discussed later in
this document, we do not anticipate that Eglin AFB's Maritime WSEP
activities will result in any serious injury or mortality to marine
mammals.
For Eglin AFB, this will be the third such Maritime WSEP
Authorization following the Authorization issued effective from
February 4, 2016, through February 3, 2017 (see 81 FR 7307; February
11, 2016). This Authorization will be effective from February 4, 2017,
through February 3, 2018. The monitoring report associated with the
2016 Authorization is available at www.nmfs.noaa.gov/pr/permits/incidental/military.htm and provides additional environmental
information related to issuance of this Authorization.
Description of the Specified Activity
Overview
Eglin AFB will conduct live ordnance testing and training in the
EGTTR within the Gulf of Mexico as part of the Maritime WSEP
operational testing missions. The Maritime WSEP test objectives are to
evaluate maritime deployment data, evaluate tactics, techniques and
procedures, and to determine the impact of techniques and procedures on
combat Air Force training. The need to conduct this type of testing has
developed in response to increasing threats at sea posed by operations
conducted from small boats, which can carry a variety of weapons, can
form in large or small numbers, and may be difficult to locate, track,
and engage in the marine environment. Because of limited Air Force
aircraft and munitions testing on engaging and defeating small boat
threats, Eglin AFB will employ live munitions against boat targets in
the EGTTR in order to continue development of techniques and procedures
to train Air Force strike aircraft to counter small maneuvering surface
vessels.
Dates and Duration
Eglin AFB will schedule up to eight Maritime WSEP training missions
occurring during a one-week period in February 2017 and a one-week
period in March 2017. The missions will occur for up to four hours each
day during the morning hours, with multiple live munitions being
released per day. However, the Authorization is effective to cover
those activities anytime during the period from February 4, 2017
through February 3, 2018.
Specified Geographic Region
The specific planned mission location is approximately 17 miles
(mi) (27.3 kilometers (km)) offshore from Santa Rosa Island, Florida,
in nearshore waters of the continental shelf in the Gulf of Mexico. All
activities will place within the EGTTR, defined as the
[[Page 10749]]
airspace over the Gulf of Mexico controlled by Eglin AFB, beginning at
a point 3 nautical miles (nmi) (3.5 mi; 5.5 km) from shore. The EGTTR
consists of subdivided blocks including Warning Area 151 (W-151) where
the activities will occur, specifically in sub-area W-151A (shown in
Figure 1).
W-151: The inshore and offshore boundaries of W-151 are roughly
parallel to the shoreline contour. The shoreward boundary is 3 nmi (3.5
mi; 5.5 km) from shore, while the seaward boundary extends
approximately 85 to 100 nmi (97.8 mi; 157.4 km to 115 mi; 185.2 km)
offshore, depending on the specific location. W-151 covers a surface
area of approximately 10,247 square nmi (nmi\2\) (13,570 square mi
(mi\2\); 35,145 square km (km\2\)), and includes water depths ranging
from about 20 to 700 meters (m) (65.6 to 2296.6 feet (ft)). This range
of depth includes continental shelf and slope waters. Approximately
half of W-151 lies over the shelf.
W-151A: W-151A extends approximately 60 nmi (69.0 mi; 111.1 km)
offshore and has a surface area of 2,565 nmi\2\ (3,396.8 mi\2\; 8,797
km\2\). Water depths range from about 30 to 350 m (98.4 to 1148.2 ft)
and include continental shelf and slope zones. However, most of W-151A
occurs over the continental shelf, in water depths less than 250 m
(820.2 ft). Maritime WSEP training missions will occur in the
shallower, northern inshore portion of the sub-area, in a water depth
of about 35 m (114.8 ft).

Detailed Description of Activities
The Maritime WSEP training missions include the release of multiple
types of inert and live munitions from fighter and bomber aircraft,
unmanned aerial vehicles, and gunships against small, static, towed,
and remotely-controlled boat targets. Munition types include bombs,
missiles, rockets, and gunnery rounds (Table 1).

The Maritime WSEP training activities involve detonations above the
water, near the water surface, and under water within the EGTTR.
However, because the tests will focus on weapons/target interaction,
Eglin AFB will not specify a particular aircraft for a given test as
long as it meets the delivery parameters.
Eglin AFB will deploy the munitions against static, towed, and
remotely-controlled boat targets within the W-151A. Eglin AFB will
operate the remote-controlled boats from an instrumentation barge
(i.e., the Gulf Range Armament Test Vessel (GRATV)) anchored on site
within the test area. The GRATV provides a platform for video cameras
and weapons-tracking equipment.

At least two ordnance delivery aircraft will participate in each
live weapons release training mission, which lasts approximately four
hours. Before delivering the ordnance, mission aircraft will make a dry
run over the target area to ensure that it is clear of commercial and
recreational boats. Jets will fly at a minimum air speed of 300 knots
(approximately 345 miles per hour, depending on atmospheric conditions)
and at a minimum altitude of 305 m (1,000 ft). Due to the limited
flyover duration and potentially high speed and altitude, the pilots
will not participate in visual surveys for protected species.
Eglin AFB's 2016 and 2015 Authorization renewal request, 2014
application for the same activities, and 2015 EA and Finding of No
Significant Impact (FONSI) contain additional detailed information on
the Maritime WSEP training activities and are all available online
(www.nmfs.noaa.gov/pr/permits/incidental/military.htm). NMFS provided
detailed descriptions of the Maritime WSEP training operations in a
previous notice for the proposed Authorization (81 FR 83209; November
21, 2016). This information has not changed between the proposed
Authorization and this final notice announcing the issuance of the
Authorization.
Comments and Responses
A notice of receipt of Eglin AFB's application and NMFS' proposal
to issue an Authorization to the U.S. Air Force, Eglin AFB, published
in the Federal Register on November 21, 2016 (81 FR 83209). During the
30-day public comment period, NMFS received comments from the Marine
Mammal Commission (MMC) and one concerned citizen. Following, are the
comments received from the MMC and the concerned citizen, as well as
NMFS' responses.
MMC Comment 1: MMC recommended that NMFS (1) follow NMFS policy of
a 24-hour reset for enumerating the number of each species that could
be taken during the proposed activities; (2) apply standard rounding
rule before summing the numbers of estimated takes across days; and (3)
for species that have the potential to be taken but model-estimated or
calculated takes round to zero, use group size to inform the take
estimates--The MMC recommended that NMFS use these methods consistently
for all future incidental take authorizations.
Response: Calculating predicted take is not an exact science, and
there are
[[Page 10751]]
arguments for taking different mathematical approaches in different
situations and for making qualitative adjustments in other situations.
NMFS is currently engaged in developing a protocol to guide more
consistent take calculations given certain circumstances. However, we
believe that the method used here supports the most appropriate take
estimate for this action and does not run counter to any ``24-hour
reset policy.''
MMC Comment 2: The MMC states that Eglin AFB has used, and proposes
to continue the use of live-feed video cameras to supplement its
effectiveness in detecting marine mammals when implementing mitigation
measures. However, the MMC is not convinced that those measures are
sufficient to effectively monitor for marine mammals entering the
training areas during the 30-minute timeframe prior to detonation. In
addition, the MMC states that it does not believe that Eglin AFB can
deem the Level A harassment zone clear of marine mammals when using
only three video cameras for monitoring. Thus, the MMC recommends that
NMFS require Eglin AFB to (1) supplement its mitigation measures with
passive acoustic monitoring and (2) determine the effectiveness of its
suite of mitigation measures for activities at Eglin prior to
incorporating presumed mitigation effectiveness into its take
estimation analyses or negligible impact determinations.
Response: NMFS has worked closely with Eglin AFB over the past
several Authorization cycles to develop proper mitigation, monitoring,
and reporting requirements designed to minimize and detect impacts from
the specified activities and ensure that NMFS can make the findings
necessary for issuance of an Authorization. Further, the take
estimation and negligible impact determinations in this Authorization
do not rely on a presumption of mitigation effectiveness. Take
estimates were based on modeling efforts and were not reduced due to
mitigation measures.
Monitoring also includes vessel-based observers for marine species
up to 30 minutes prior to deploying live munitions in the area. Eglin
AFB has submitted annual reports to NMFS every year that describes all
activities that occur in the EGTTR. In addition, Eglin AFB submitted
annual reports to NMFS at the conclusion of the Maritime Strike
Operations These missions are similar in nature to the maritime WSEP
operations and the Eglin AFB provided information on sighting
information and results from post-mission survey observations. Based on
those results, NMFS determined that the mitigation measures ensured the
least practicable adverse impact to marine mammals. There were no
observations of injured marine mammals and no reports of marine mammal
mortality during the Maritime Strike Operation activities. The measures
for the Maritime WSEP are similar, except they will include larger
survey areas based on updated acoustic analysis and previous
discussions with the MMC and NMFS.
Eglin AFB will continue to research the feasibility of
supplementing existing monitoring efforts with passive acoustic
monitoring devices for future missions, and has recently requested
funding to do so. However, even if this funding request is approved,
the funds will not be available to implement the additional measures
for this Authorization. If funding is approved, passive acoustic
monitoring will be included in future missions that may be part of the
proposed rule to cover multiple activities in the EGTTR.
Concerned Citizen Comment 1: The private citizen commented that the
U.S. Air Force should ``bomb dead areas like the Gulf of Mexico where
no life can live anyway'', and expressed opposition to the U.S. Air
Force proposed Maritime WSEP activities out of concern that endangered
animals would be harmed.
Response: As noted in the Federal Register on November 21, 2016 (81
FR 83209), the Maritime WSEP activities will take place in the Gulf of
Mexico. In addition, due to the location of the activities, no
threatened or endangered species are anticipated to be taken and NMFS
has not authorized any take of threatened or endangered species.
Finally, the information presented in the notice for the proposed
Authorization (81 FR 83209; November 21, 2016) indicates that modeling
results show zero takes for mortality, and three takes by Level A
harassment. We make a correction: Table 9 of the proposed Authorization
indicated these three Level A takes were for permanent threshold shift
(PTS) only. However, the correct estimate includes three PTS takes and
one slight lung injury take. However, NMFS does not believe that
serious injury will result from this activity and that therefore it is
not necessary to issue regulations through section 101(a)(5)(A) of the
MMPA, rather, an IHA is appropriate.

break (i.e., water depth of approximately 200 m (656.2 ft)) located
beyond the W-151A test area. NMFS and Eglin AFB consider these 19
species to be rare or extralimital within the W-151A test location
area. These species are the Bryde's whale (Balaenoptera edeni), sperm
whale (Physeter macrocephalus), dwarf sperm whale (Kogia sima), pygmy
sperm whale (K. breviceps), pantropical spotted dolphin (Stenella
attenuata), Clymene dolphin (S. clymene), spinner dolphin (S.
longirostris), striped dolphin (S. coeruleoalba), Blainville's beaked
whale (Mesoplodon densirostris), Gervais' beaked whale (M. europaeus),
Cuvier's beaked whale (Ziphius cavirostris), killer whale (Orcinus
orca), false killer whale (Pseudorca crassidens), pygmy killer whale
(Feresa attenuata), Risso's dolphin (Grampus griseus), Fraser's dolphin
(Lagenodelphis hosei), melon-headed whale (Peponocephala electra),
rough-toothed dolphin (Steno bredanensis), and short-finned pilot whale
(Globicephala macrorhynchus).
Of these species, only the sperm whale is listed as endangered
under the Endangered Species Act (ESA) and as depleted throughout its
range under the MMPA. Sperm whale occurrence within W-151A is unlikely
because almost all reported sightings have occurred in water depths
greater than 200 m (656.2 ft).
Because these species are unlikely to occur within the W-151A area,
Eglin AFB has not requested and we are not proposing to authorize take
for them. Thus, we do not consider these species further in this
notice.
We have reviewed Eglin AFB's species descriptions, including life
history information, distribution, regional distribution, diving
behavior, and acoustics and hearing, for accuracy and completeness.
That information is contained in sections 3 and 4 of Eglin AFB's 2016
Authorization application and in Chapter 3 of Eglin AFB's Environmental
Assessment (EA) and we incorporate those sections by reference rather
than reprinting the information here.
Other Marine Mammals in the Action Area
The endangered West Indian manatee (Trichechus manatus) rarely
occurs in the area (USAF 2014). The U.S. Fish and Wildlife Service has
jurisdiction over the manatee; therefore, we did not include an
Authorization to harass manatees and do not discuss this species
further in this notice.
Potential Effects of the Specified Activity on Marine Mammals and Their
Habitat
This section of the notice of the proposed Authorization (81 FR
83209, November 21, 2016) included a summary and discussion of the ways
that components (e.g., exposure to impulsive noise and pressure waves
generated by live ordnance detonation at or near the surface of the
water) of the specified activity, including mitigation, may impact
marine mammals and their habitat. The ``Estimated Take by Incidental
Harassment'' section later in this document will include a quantitative
analysis of the number of individuals that we expect Eglin AFB to take
during this activity. The ``Negligible Impact Analysis'' section will
include the analysis of how this specific activity will impact marine
mammals. We will consider the content of the following sections:
``Estimated Take by Incidental Harassment'' and ``Mitigation'' to draw
conclusions regarding the likely impacts of these activities on the
reproductive success or survivorship of individuals--and from that
consideration--the likely impacts of this activity on the affected
marine mammal populations or stocks.
In summary, the Maritime WSEP training exercises under this
Authorization have the potential to take marine mammals by exposing
them to impulsive noise and pressure waves generated by live ordnance
detonation at or near the surface of the water. Exposure to energy or
pressure resulting from these detonations could result in Level A
harassment (PTS and slight lung injury) and by Level B harassment
(temporary threshold shift (TTS) and behavioral harassment). In
addition, NMFS also considered the potential for harassment from vessel
operations.
The potential effects of impulsive sound sources (underwater
detonations) from the training activities may include one or more of
the following: Tolerance, masking, disturbance, hearing threshold
shift, stress response, and mortality. NMFS provided detailed
information on these potential effects in the notice of the proposed
Authorization (81 FR 83209; November 21, 2016). The information
presented in that notice has not changed.
Anticipated Effects on Habitat
Detonations of live ordnance will result in temporary changes to
the water environment. Munitions could hit the targets and not explode
in the water. However, because the targets are located over the water,
in water explosions could occur. An underwater explosion from these
weapons could send a shock wave and blast noise through the water,
release gaseous by-products, create an oscillating bubble, and cause a
plume of water to shoot up from the water surface. However, these
effects will be temporary and not expected to last more than a few
seconds.
Similarly, Eglin AFB does not expect any long-term impacts with
regard to hazardous constituents to occur. Eglin AFB considered the
introduction of fuel, debris, ordnance, and chemical materials into the
water column within its EA and determined the potential effects of each
to be insignificant. NMFS provided a summary of the analyses in the
notice for the proposed Authorization (81 FR 83209; November 21, 2016).
The information presented in that notice has not changed.
Mitigation
In order to issue an Authorization under section 101(a)(5)(D) of
the MMPA, NMFS must set forth the permissible methods of taking
pursuant to such activity, and other means of effecting the least
practicable adverse impact on such species or stock and its
[[Page 10753]]
habitat, paying particular attention to rookeries, mating grounds, and
areas of similar significance, and the availability of such species or
stock for taking for certain subsistence uses (where relevant).
The NDAA of 2004 amended the MMPA as it relates to military-
readiness activities and the incidental take authorization process such
that ``least practicable adverse impact'' shall include consideration
of personnel safety, practicality of implementation, and impact on the
effectiveness of the military readiness activity.
NMFS and Eglin AFB worked to identify potential practicable and
effective mitigation measures, which include a careful balancing of the
likely benefit of any particular measure to the marine mammals with the
likely effect of that measure on personnel safety, practicality of
implementation, and impact on the ``military-readiness activity.'' We
refer the reader to section 11 of Eglin AFB's application for more
detailed information on mitigation measures which include the
following:
Vessel-Based Monitoring
Eglin AFB will station a large number of range clearing boats
(approximately 30 to 35) around the test site to prevent non-
participating vessels from entering the human safety zone. Based on the
composite footprint, range clearing boats will be located approximately
15.28 km (9.5 mi) from the detonation point (see Figure 11-1 in Eglin
AFB's application). However, the actual distance will vary based on the
size of the munition being deployed.
Trained protected species observers (PSO) will be aboard five of
these boats and will conduct protected species surveys before and after
each test. The protected species survey vessels will be dedicated
solely to observing for marine species during the pre-mission surveys
while the remaining safety boats clear the area of non-authorized
vessels. The protected species survey vessels will begin surveying the
area at sunrise. The area to be surveyed will encompass the zone of
influence (ZOI), which is discussed in more detail below.
Because of human safety issues, PSOs will be required to leave the
test area at least 30 minutes in advance of live weapon deployment and
move to a position on the safety zone periphery, approximately 15.28 km
(9.5 mi) from the detonation point. PSOs will continue to scan for
marine mammals from the periphery. Animals that may enter the area
after Eglin AFB has completed the pre-mission surveys and prior to
detonation will not reach the predicted smaller slight lung injury and/
or mortality zones due to their swim speed and the size of the
clearance zone.
Determination of the Zone of Influence
Historically, Eglin AFB has conservatively used the number of live
weapons deployed to estimate take of marine mammals. This method
assumed a fresh population of marine mammals for each detonation to
calculate the number taken. However, NMFS requested mission-day
scenarios in order to be able to model accumulated energy. Therefore,
each mission-day scenario is considered a separate event to model takes
as opposed to modeling for each live detonation. Eglin AFB developed
three mission-day categories (Category A, which represents levels of
activities considered a worst-case scenario consisting of ordnances
with large explosive weights as well as surface and subsurface
detonations; Category B, which represents a `typical' mission day based
on levels of weapons releases during past Maritime WSEP activities; and
Category C, which represents munitions with smaller explosive weights
and surface detonations only), and estimated the number of days each
category will be executed during the 2017 Maritime WSEP missions (See
Table 1-3 in Eglin AFB's application for the Mission Day Scenarios).
Table 4 below provides the categorization of mission days (Table 1-3 in
Eglin AFB's application), and Table 5 provides the maximum range of
effects for all criteria and thresholds for mission-day Categories A,
B, and C. These ranges were calculated based on explosive acoustic
characteristics, sound propagation, and sound transmission loss in the
study area (which incorporates water depth, sediment type, wind speed,
bathymetry, and temperature/salinity profiles). Refer to Appendix A of
Eglin AFB's application for a complete description of the acoustic
modeling methodology used in the analysis.

Mortality and slight lung injury threshold ranges would extend from
47 to 216 m and 84 to 595 m, respectively, depending on the mission-day
category. These ranges would fall within the Level A harassment ranges.
Based on the planned activities on a given mission day, and the ranges
presented in Table 5, Eglin AFB will ensure that the area equating to
the Level A harassment threshold range is free of protected species. By
clearing the Level A harassment threshold range of protected species,
animals that may enter the area after the completed pre-mission surveys
but prior to detonation would not reach the smaller slight lung injury
or mortality zones as explained above. Because of human safety issues,
Eglin AFB will require PSOs to leave the test area at least 30 minutes
in advance of live weapon deployment and move to a position on the
safety zone periphery, approximately 15 km (9.5 mi) from the detonation
point. PSOs will continue to scan for marine mammals from the
periphery, but effectiveness will be limited as the boat will remain at
a designated station.
Video Monitoring: In addition to vessel-based monitoring, Eglin AFB
will position three high-definition video cameras on the GRATV anchored
on-site, as described earlier, to allow for real-time monitoring for
the duration of the mission. The camera configuration and actual number
of cameras used will depend on specific mission requirements. In
addition to monitoring the area for mission objective issues, the
camera(s) will also monitor for the presence of protected species. A
trained marine species observer from Eglin Natural Resources will be
located in Eglin AFB's Central Control Facility, along with mission
personnel, to view the video feed before and during test activities.
The distance to which objects can be detected at the water surface by
use of the cameras is considered generally comparable to that of the
human eye.
The GRATV will be located about 183 m (600 ft) from the target. The
mortality threshold ranges correspond to the modified Goertner model
adjusted for the weight of an Atlantic spotted dolphin calf, and extend
from 0 to 216 m (0 to 709 ft) from the target, depending on the
ordnance, and the Level A ranges for both common bottlenose and
Atlantic spotted dolphins extend up to 945 m (3,100 ft) from the
target, depending on the ordnance and harassment criterion. Given these
distances, observers can reasonably be expected to view a substantial
portion of the mortality zone in front of the camera, although a small
portion would be behind or to the side of the camera view. Based on
previous monitoring reports for this activity, the pre-training surveys
for delphinids and other protected species within the mission area are
effective. PSOs can view some portion of the Level A harassment zone,
although the view window will be less than that of the mortality zone
(a large percentage will be behind or to the side of the camera view).
In addition to the two types of visual monitoring discussed earlier
in this section, Eglin AFB personnel will be present within the mission
area (on boats and on the GRATV) on each day of testing well in advance
of weapon deployment, typically near sunrise. They will perform a
variety of tasks including target preparation, equipment checks, etc.,
and will opportunistically observe for marine mammals and indicators as
feasible throughout test preparation. However, we consider these
observations as supplemental to the mitigation and monitoring and will
only occur as time and schedule permits. Eglin AFB personnel will relay
information on these types of sightings to the Lead Biologist, as
described in the following mitigation sections.
Pre-Mission Monitoring
The purposes of pre-mission monitoring are to: (1) Evaluate the
mission site for environmental suitability, and (2) verify that the ZOI
is free of visually detectable marine mammals, as well as potential
indicators of these species. On the morning of the mission, the Test
Director and Safety Officer will confirm that there are no issues that
will preclude mission execution and that weather is adequate to support
mitigation measures.
Sunrise or Two Hours Prior to Mission
Eglin AFB range clearing vessels and protected species survey
vessels will be on site at least two hours prior to the mission. The
Lead Biologist on board one survey vessel will assess the overall
suitability of the mission site based on environmental conditions (sea
state) and presence/absence of marine mammal indicators. Eglin AFB
personnel will communicate this information to Tower Control and
personnel will relay the information to the Safety Officer in Central
Control Facility.
One and One-Half Hours Prior to Mission
Vessel-based surveys will begin approximately one and one-half
hours prior to live weapons deployment. Surface vessel PSOs will survey
the ZOI and relay all marine species and indicator sightings, including
the time of sighting, GPS location, and direction of travel, if known,
to the Lead Biologist. The Lead Biologist will document all sighting
information on report forms that he/she will submit to Eglin Natural
Resources after each mission. Surveys will continue for approximately
one hour. During this time, Eglin AFB personnel in the mission area
will also observe for marine species as feasible. If marine mammals or
indicators are observed within the ZOI for that day's mission
activities, the range will be declared ``fouled,'' a term that
signifies to mission personnel that conditions are such that a live
ordnance drop cannot occur (e.g., protected species or civilian vessels
are in the mission area). If there are no observations of marine
mammals or indicators of marine mammals, Eglin AFB will declare the
range clear of protected species.
One-Half Hour Prior to Mission
At approximately 30 minutes prior to live weapon deployment, marine
species PSOs will be instructed to leave the mission site and remain
outside the safety zone, which on average will be 15.28 km (9.5 mi)
from the detonation point. The actual size is determined by weapon net
explosive weight and method of delivery. The survey team will continue
to monitor for protected
[[Page 10755]]
species while leaving the area. As the survey vessels leave the area,
marine species monitoring of the immediate target areas will continue
at the Central Control Facility through the live video feed received
from the high definition cameras on the GRATV. Once the survey vessels
have arrived at the perimeter of the safety zone (approximately 30
minutes after leaving the area per instructions from Eglin AFB,
depending on actual travel time), Eglin AFB will declare the range as
``green'' and the mission will proceed, assuming all non-participating
vessels have left the safety zone as well.
Execution of Mission
Immediately prior to live weapons drop, the Test Director and
Safety Officer will communicate to confirm the results of marine mammal
surveys and the appropriateness of proceeding with the mission. The
Safety Officer will have final authority to proceed with, postpone, or
cancel the mission. Eglin AFB will postpone the mission if:
Any of the high-definition video cameras are not
operational for any reason;
Any marine mammal is visually detected within the ZOI.
Postponement will continue until the animal(s) that caused the
postponement is: (1) Confirmed to be outside of the ZOI and heading
away from the targets; or (2) not seen again for 30 minutes and
presumed to be outside the ZOI due to the animal swimming out of the
range;
Any large schools of fish or large flocks of birds feeding
at the surface are within the ZOI. Postponement will continue until
Eglin AFB personnel confirm that these potential indicators are outside
the ZOI:
Any technical or mechanical issues related to the aircraft
or target boats; or
Any non-participating vessel enters the human safety zone
prior to weapon release.
In the event of a postponement, protected species monitoring will
continue from the Central Control Facility through the live video feed.
Observers will also continue to monitor from the vessels at the safety
perimeter, with limited effectiveness due to the distance from the
detonation site.
Post-Mission Monitoring
Post-mission monitoring determines the effectiveness of pre-mission
mitigation by reporting sightings of any marine mammals. Post-
detonation monitoring surveys will commence once the mission has ended
or, if required, as soon as personnel declare the mission area safe.
Vessels will move into the survey area from outside the safety zone and
monitor for at least 30 minutes, concentrating on the area down-current
of the test site. This area is easily identifiable because of the
floating debris in the water from impacted targets. Up to 10 Eglin AFB
support vessels will be cleaning debris and collecting damaged targets
from this area thus spending several hours in the area once Eglin AFB
completes the mission. PSOs will document and report any marine mammal
species, number, location, and behavior of any animals observed to
Eglin Natural Resources.
Mission Delays Due to Weather
Eglin AFB will delay or reschedule Maritime WSEP missions if the
Beaufort sea state is greater than number 4 at the time of the testing
activities. The Lead Biologist aboard one of the survey vessels will
make the final determination of whether conditions are conducive for
sighting protected species or not.
We have carefully evaluated Eglin AFB's mitigation measures in the
context of ensuring that we prescribe the means of effecting the least
practicable impact on the affected marine mammal species and stocks and
their habitat. Our evaluation of potential measures included
consideration of the following factors in relation to one another:
The manner in which, and the degree to which, the
successful implementation of the measure is expected to minimize
adverse impacts;
The proven or likely efficacy of the specific measure to
minimize adverse impacts as planned; and
The practicability of the measure for applicant
implementation.
Any mitigation measure(s) prescribed by NMFS should be able to
accomplish, have a reasonable likelihood of accomplishing (based on
current science), or contribute to the accomplishment of one or more of
the general goals listed here:
1. Avoidance or minimization of injury or death of marine mammals
wherever possible (goals 2, 3, and 4 may contribute to this goal);
2. A reduction in the numbers of marine mammals (total number or
number at biologically important times or locations) exposed to stimuli
expected to result in incidental take (this goal may contribute to 1,
above, or to reducing takes by behavioral harassment only);
3. A reduction in the number of times (total number or number at
biologically important times or locations) individuals will be exposed
to stimuli that we expect to result in the take of marine mammals (this
goal may contribute to 1, above, or to reducing harassment takes only);
4. A reduction in the intensity of exposures (either total number
or number at biologically important times or locations) to training
exercises that we expect 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; and
6. For monitoring directly related to mitigation--an increase in
the probability of detecting marine mammals, thus allowing for more
effective implementation of the mitigation.
Based on our evaluation of Eglin AFB's mitigation measures, as well
as other measures that may be relevant to the specified activity, we
have determined that the mitigation measures provide the means of
effecting the least practicable impact on marine mammal species or
stocks and their habitat, paying particular attention to rookeries,
mating grounds, and areas of similar significance (while also
considering personnel safety, practicality of implementation, and the
impact of effectiveness of the military readiness activity).
Monitoring and Reporting
In order to issue an Authorization for an activity, section
101(a)(5)(D) of the MMPA states that we must set forth ``requirements
pertaining to the monitoring and reporting of such taking.'' The MMPA
implementing regulations at 50 CFR 216.104(a)(13) indicate that
requests for an authorization must include the suggested means of
accomplishing the necessary monitoring and reporting that will result
in increased knowledge of the species and our expectations of the level
of taking or impacts on populations of marine mammals present in the
action area.
Eglin AFB submitted a marine mammal monitoring plan in their
Authorization application. NMFS has not modified or supplemented the
plan based on comments or new information received from the public
during the public comment period. Any monitoring requirement we
prescribe should improve our understanding of one or more of the
following:
[[Page 10756]]
Occurrence of marine mammal species or stocks in action
area (e.g., presence, abundance, distribution, density);
Nature, scope, or context of likely marine mammal exposure
to potential stressors/impacts (individual or cumulative, acute or
chronic), through better understanding of: (1) Action or environment
(e.g., source characterization, propagation, ambient noise); (2)
Affected species (e.g., life history, dive patterns); (3) Co-occurrence
of marine mammal species with the action; or (4) Biological or
behavioral context of exposure (e.g., age, calving or feeding areas);
Individual responses to acute stressors, or impacts of
chronic exposures (behavioral or physiological);
How anticipated responses to stressors impact either: (1)
Long-term fitness and survival of an individual; or (2) Population,
species, or stock;
Effects on marine mammal habitat and resultant impacts to
marine mammals; and
Mitigation and monitoring effectiveness.
The Authorization for Maritime WSEP operations will require the
following measures:
(1) Eglin AFB will track the use of the EGTTR for test firing
missions and protected species observations through the use of mission
reporting forms;
(2) Eglin AFB will submit a summary report of marine mammal
observations and Maritime WSEP activities to the NMFS Southeast
Regional Office (SERO) and the Office of Protected Resources 90 days
after expiration of the current Authorization. This report must include
the following information: (i) Date and time of each Maritime WSEP
exercise; (ii) a complete description of the pre-exercise and post-
exercise activities related to mitigating and monitoring the effects of
Maritime WSEP exercises on marine mammal populations; and (iii) results
of the Maritime WSEP exercise monitoring, including number of marine
mammals (by species) that may have been harassed due to presence within
the activity zone;
(3) Eglin AFB will monitor for marine mammals in the action area.
If Eglin AFB personnel observe or detect any dead or injured marine
mammals prior to testing, or detects any injured or dead marine mammals
during live fire exercises, Eglin AFB must cease operations and submit
a report to NMFS within 24 hours; and
(4) Eglin AFB must immediately report any unauthorized takes of
marine mammals (i.e., serious injury or mortality) to NMFS and to the
respective Southeast Region stranding network representative. Eglin AFB
must cease operations and submit a report to NMFS within 24 hours.
Monitoring Results From Previously Authorized Activities
Eglin AFB complied with the mitigation and monitoring required
under the previous Authorization for 2016 Maritime WSEP activities.
Marine mammal monitoring occurred before, during, and after each
Maritime WSEP mission. During the course of these activities, Eglin
AFB's monitoring reports showed that they did not exceed the take
levels authorized. In accordance with the 2015 Authorization, Eglin AFB
submitted a monitoring report (available at: www.nmfs.noaa.gov/pr/permits/incidental/military.htm).
Under the 2016 Authorization, Eglin AFB anticipated conducting
Maritime WSEP training missions over approximately two to three weeks,
but actually conducted a total of five mission days (February 11 and
March 14-17) associated with live ordnance delivery. Due to weather
conditions and high sea states, no live missions were conducted
February 8-10. Munitions that were actually dropped accounted for only
approximately 41 percent of what was authorized in the 2016
Authorization.
During the February 2016 mission, Eglin AFB released one AGM-65
Maverick. The AGM-65 Maverick is a penetrating blast-fragment warhead
that detonates at the surface and has 86 lb NEW. Eglin AFB conducted
the required monitoring for marine mammals or indicators of marine
mammals (e.g., flocks of birds, baitfish schools, or large fish
schools) before, during, and after each mission and observed a mixture
of six bottlenose and spotted dolphins approximately seven miles
outside of the largest ZOI, so no action was required. No protected
species were observed within the ZOI during pre-mission surveys,
mission activities, or during post-mission surveys. Therefore, the
mission resulted in no acoustic impacts to marine mammals.
During the March 2016 live fire missions, Eglin AFB expended two
AGM-65 Mavericks and twelve AGM-114 Hellfire missiles. The NEW of the
munitions that detonated at the water surface or up to 3 m (10 ft)
below the surface are 86 lb for the AGM-65 Maverick missiles and 13 lb
for the AGM-114 Hellfire missiles. Eglin AFB conducted the required
monitoring for marine mammals or indicators of marine mammals (e.g.,
flocks of birds, baitfish schools, or large fish schools) before,
during, and after each mission and observed two species of marine
mammals: The common bottlenose dolphin and Atlantic spotted dolphin;
one sea turtle; and two flocks of approximately 10-20 birds on two
separate occasions (upon investigation there was no evidence of
protected species associated with either flock of birds). Eglin AFB
confirmed that all protected species observed were outside of the ZOI
at the conclusion of each pre-mission survey.
After each mission, Eglin AFB re-entered the ZOI to begin post-
mission surveys for marine mammals and debris clean-up operations.
Eglin AFB personnel did not observe reactions indicative of disturbance
during the pre-mission surveys and did not observe any marine mammals
during the post-mission surveys. In summary, Eglin AFB reports that no
observable instances of take of marine mammals occurred incidental to
the Maritime WSEP training activities under the 2016 Authorization.
Estimated Numbers of Marine Mammals Taken by Harassment
This section includes an estimate of the number of incidental
``takes'' proposed for authorization pursuant to this Authorization,
which will inform both NMFS negligible impact determination. Harassment
is the means of take expected to result from these activities, and the
definition of harassment as it applies to a ``military readiness
activity'' is: (i) Any act that injures or has the significant
potential to injure a marine mammal or marine mammal stock in the wild
(Level A Harassment); or (ii) any act that disturbs or is likely to
disturb a marine mammal or marine mammal stock in the wild by causing
disruption of natural behavioral patterns, including, but not limited
to, migration, surfacing, nursing, breeding, feeding, or sheltering, to
a point where such behavioral patterns are abandoned or significantly
altered (Level B Harassment).
NMFS' analysis identified the physiological responses and
behavioral responses that could potentially result from exposure to
underwater explosive detonations. In this section, we will relate the
potential effects to marine mammals from underwater detonation of
explosives to the MMPA regulatory definitions of Level A and Level B
harassment. This section will also quantify the effects that might
occur from the military readiness activities in W-151.
At NMFS' recommendation, Eglin AFB updated the thresholds used for
onset of TTS (Level B Harassment) and onset of PTS (Level A Harassment)
to be
[[Page 10757]]
consistent with the thresholds outlined in NMFS' August 2016
``Technical Guidance for Assessing the Effects of Anthropogenic Sound
on Marine Mammal Hearing'' (NMFS 2016). NMFS believes that the
thresholds outlined in the new Technical Guidance represent the best
available science. The report is available on the internet at:
www.nmfs.noaa.gov/pr/acoustics/Acoustic%20Guidance%20Files/opr-55_acoustic_guidance_tech_memo.pdf.
Level B Harassment
Of the potential effects described earlier in this document, the
following are the types of effects that fall into the Level B
harassment category:
Behavioral Harassment
Behavioral disturbance that rises to the level described in the
above definition, when resulting from exposures to non-impulsive or
impulsive sound, is Level B harassment. Some of the lower level
physiological stress responses discussed earlier will also likely co-
occur with the predicted harassments, although these responses are more
difficult to detect and fewer data exist relating these responses to
specific received levels of sound. When predicting Level B harassment
based on estimated behavioral responses, we are aware that those takes
may have a stress-related physiological component.
Temporary Threshold Shift
As discussed previously, TTS can affect how an animal behaves in
response to the environment, including conspecifics, predators, and
prey. NMFS classifies TTS (when resulting from exposure to explosives
and other impulsive sources) as Level B harassment, not Level A
harassment (injury).
Level A Harassment
Of the potential effects that were described earlier, the following
are the types of effects that fall into the Level A Harassment
category:
Permanent Threshold Shift
PTS (resulting either from exposure to explosive detonations) is
irreversible and NMFS considers this to be an injury.
Acoustic Thresholds
Table 6 outlines the acoustic thresholds for mid-frequency
cetaceans used by NMFS for this Authorization when addressing noise

spotted dolphins are considered mid-frequency cetaceans.

dB = decibels; GI = gastrointestinal; SEP = sound exposure level; SPL = sound pressure level; PTS = permanent threshold shift; TTS = temporary threshold

The ranges presented above were used to calculate the ZOI for each
criterion/threshold. To eliminate double counting of takes, impact
areas from higher impact categories (e.g., PTS) were subtracted from
areas associated with lower impact categories (e.g., TTS). The
estimated number of marine mammals potentially exposed to the various
[[Page 10758]]
impact thresholds was calculated with a two-dimensional approach using
the product of the adjusted impact area, animal density, and annual
number of events for each mission-day category. A take is considered to
occur for sound exposure level (SEL) metrics if the received level is
equal to or above the associated threshold within the appropriate
frequency band of the sound received, adjusted for the appropriate
weighting function value of that frequency band. Similarly, a take
would occur for impulse and peak SPL metrics if the received level is
equal to or above the associated threshold.
Density Estimation
Density estimates for bottlenose dolphin and spotted dolphin were
obtained from Duke University Marine Geospatial Ecology Lab Reports
(Roberts et al., 2016). Raster data from Duke University were imported
into ArcGIS and overlaid onto the Maritime WSEP mission area. Density
values were provided in 100 km\2\ boxes. A 30-km by 30-km (900 km\2\)
area centered on the Maritime WSEP mission location was selected, which
consisted of nine 100-km\2\ blocks. Density values from those blocks
were averaged and converted to number of animals per square kilometer
to obtain average annual density estimates for the common bottlenose
and Atlantic spotted dolphins used in this analysis (see Table 8 for
the resultant densities for these species).

Take Estimation
Table 9 indicates the modeled potential for lethality, injury, and
non-injurious harassment (including behavioral harassment) to marine
mammals in the absence of mitigation measures. Eglin AFB and NMFS
estimate that approximately three marine mammals could be exposed to
injurious Level A harassment noise levels (187 dB SEL) and
approximately 326 animals could be exposed to Level B harassment (TTS
and behavioral harassment) noise levels in the absence of mitigation
measures.

Based on the mortality exposure estimates calculated by the
acoustic model and the anticipated effectiveness of mitigation
measures, zero marine mammals are expected to be affected by pressure
levels associated with mortality or serious injury. Zero marine mammals
are expected to be exposed to pressure levels associated with
gastrointestinal tract injury.
NMFS generally considers PTS to fall under the injury category
(Level A Harassment). An animal would need to stay very close to the
sound source for an extended amount of time to incur a serious degree
of PTS, which could increase the probability of mortality. In this
case, it would be highly unlikely for this scenario to unfold given the
nature of any anticipated acoustic exposures that could potentially
result from a mobile marine mammal that NMFS generally expects to
exhibit avoidance behavior to loud sounds within the EGTTR. NMFS
concludes that possibility of minor PTS in the form of slight upward
shift of hearing threshold at certain frequency bands by a few
individuals of marine mammals is low, but not unlikely. The majority of
the incidental `takes' resulting from Eglin AFB's WSEP activities will
consist of Level B harassment, such as TTS and behavioral responses.
Negligible Impact Analysis Determinations
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'' (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, we consider other factors, such as
the likely nature of any responses (e.g., intensity, duration), the
context of any responses (e.g., critical reproductive time or location,
migration), as well as the number and nature of estimated Level A
harassment takes, the number of estimated mortalities, and effects on
habitat. Consistent with the 1989 preamble for NMFS' implementing
regulations (54 FR 40338; September 29, 1989), the impacts from other
past and ongoing anthropogenic activities are incorporated into these
analyses via their impacts on the environmental baseline (e.g., as
reflected in the regulatory status of the species, populations size,
growth rate where known, ongoing sources of human-caused mortality, or
ambient noise levels).
To avoid repetition, the discussion below applies to each of the
species for which we authorize incidental take for Eglin AFB's
activities, given that expected impacts are expected to be the same for
both species.
In making a negligible impact determination, we consider:
The number of anticipated injuries, serious injuries, or
mortalities;
The number, nature, and intensity, and duration of Level B
harassment;
The context in which the takes occur (e.g., impacts to
areas of significance, impacts to local populations, and cumulative
impacts when taking into account successive/contemporaneous actions
when added to baseline data);
[[Page 10759]]
The status of stock or species of marine mammals (i.e.,
depleted, not depleted, decreasing, increasing, stable, impact relative
to the size of the population);
Impacts on habitat affecting rates of recruitment/
survival; and
The effectiveness of monitoring and mitigation measures to
reduce the number or severity of incidental take.
For reasons stated previously in this document and based on the
following factors, Eglin AFB's specified activities are not likely to
cause long-term behavioral disturbance, serious injury, or death.
The takes from Level B harassment will be due to potential
behavioral disturbance and TTS. The takes from Level A harassment will
be due to some, likely lesser, degree of PTS and slight lung injury.
Activities will only occur over a timeframe of two to three weeks
beginning in February 2017, with one or two missions occurring per day.
It is possible that some individuals may be taken more than once if
those individuals are located in the exercise area on two different
days when exercises are occurring.
Noise-induced threshold shifts (TS, which includes PTS) are defined
as increases in the threshold of audibility (i.e., the sound has to be
louder to be detected) of the ear at a certain frequency or range of
frequencies (ANSI 1995; Yost 2000). Several important factors relate to
the magnitude of TS, such as level, duration, spectral content
(frequency range), and temporal pattern (continuous, intermittent) of
exposure (Yost 2000; Henderson et al., 2008). TS occurs in terms of
frequency range (Hz or kHz), hearing threshold level (dB), or both
frequency and hearing threshold level (CDC 2004).
In addition, there are different degrees of PTS ranging from
slight/mild to moderate and from severe to profound (Clark 1981).
Profound PTS or the complete loss of the ability to hear in one or both
ears is commonly referred to as deafness (CDC 2004; WHO 2006). High-
frequency PTS, presumably as a normal process of aging that occurs in
humans and other terrestrial mammals, has also been demonstrated in
captive cetaceans (Ridgway and Carder 1997; Yuen et al., 2005; Finneran
et al., 2005; Houser and Finneran 2006; Finneran et al., 2007; Schlundt
et al., 2011) and in stranded individuals (Mann et al., 2010).
In terms of what is analyzed for the potential PTS (Level A
harassment) in marine mammals as a result of Eglin AFB's Maritime WSEP
operations, if it occurs, NMFS has determined that the levels will be
slight/mild because most cetaceans would be expected to show relatively
high levels of avoidance. Further, it is uncommon to sight marine
mammals within the target area, especially for prolonged durations.
Results from monitoring programs associated other Eglin AFB activities
and for Eglin AFB's 2016 Maritime WSEP activities have shown the
absence of marine mammals within the EGTTR during and after maritime
operations. Avoidance varies among individuals and depends on their
activities or reasons for being in the area.
NMFS' predicted estimates for Level A harassment take are likely
overestimates of the likely injury that will occur. NMFS expects that
successful implementation of the required vessel-based and video-based
mitigation measures will avoid Level A take in some instances. Also,
NMFS expects that some individuals will avoid the source at levels
expected to result in injury. Nonetheless, although NMFS expects that
Level A harassment is unlikely to occur at the numbers authorized,
because it is difficult to quantify the degree to which the mitigation
and avoidance will reduce the number of animals that might incur PTS,
we are authorizing the modeled number of Level A takes (three), which
does not take mitigation or avoidance into consideration. However, we
anticipate that any PTS incurred because of mitigation and the likely
short duration of exposures, will be in the form of only a small degree
of PTS and not total deafness.
While animals may be impacted in the immediate vicinity of the
activity, because of the short duration of the actual individual
explosions themselves (versus continual sound source operation)
combined with the short duration of the Maritime WSEP operations, NMFS
has determined that there will not be a substantial impact on marine
mammals or on the normal functioning of the nearshore or offshore Gulf
of Mexico ecosystems. We do not expect that the activity will impact
rates of recruitment or survival of marine mammals since, among other
factors listed below, we do not expect mortality (which would remove
individuals from the population) or serious injury to occur. In
addition, the activity will not occur in areas (and/or times) of
significance for the marine mammal populations potentially affected by
the exercises (e.g., feeding, resting, or reproductive areas), and the
activities will only occur in a small part of their overall range, so
the impact of any potential temporary displacement will be negligible
and animals are expected to return to the area after the cessation of
activities. Although the activity could result in Level A (PTS or
slight lung injury, not gastrointestinal tract injury) and Level B
(behavioral disturbance and TTS of lesser degree and shorter duration)
harassment of marine mammals, the level of harassment is not
anticipated to impact rates of recruitment or survival of marine
mammals because the number of exposed animals is expected to be low due
to the short-term (i.e., four hours a day or less) and site-specific
nature of the activity. We do not anticipate that the effects will be
detrimental to rates of recruitment and survival because we do not
expect serious extended behavioral responses that would result in
energetic effects at the level to impact fitness.
Moreover, the mitigation and monitoring measures for the
Authorization (described earlier in this document) are expected to
further minimize the potential for harassment. The protected species
surveys will require Eglin AFB to search the area for marine mammals,
and if any are found in the live fire area, then the exercise will be
suspended until the animal(s) has left the area. Moreover, marine
species observers located in the Eglin control tower will monitor the
high-definition video feed from cameras located on the instrument barge
anchored on-site for the presence of protected species. Furthermore,
Maritime WSEP missions will be delayed or rescheduled if the sea state
is greater than a 4 on the Beaufort Scale at the time of the test. In
addition, Maritime WSEP missions will occur no earlier than two hours
after sunrise and no later than two hours prior to sunset to ensure
adequate daylight for pre- and post-mission monitoring.
Based on the analysis contained herein of the likely effects of the
specified activity on marine mammals and their habitat, and taking into
consideration the implementation of the mitigation and monitoring
measures, NMFS finds that Eglin AFB's Maritime WSEP operations will
result in the incidental take of marine mammals, by Level A and Level B
harassment, but that the taking from the Maritime WSEP exercises will
not have an adverse effect on annual rates of recruitment or survival,
and therefore will have a negligible impact on the affected species or
stocks.
Impact on Availability of Affected Species or Stock for Taking for
Subsistence Uses
There are no relevant subsistence uses of marine mammals implicated
by this action. Therefore, NMFS has determined that the total taking of
[[Page 10760]]
affected species or stocks will not have an unmitigable adverse impact
on the availability of such species or stocks for taking for
subsistence purposes.
Endangered Species Act (ESA)
Due to the location of the activity and past experience with
similar authorizations for these activities, no ESA-listed marine
mammal species are likely to be affected. Therefore, NMFS has
determined that this Authorization will have no effect on ESA-listed
species and has determined that a section 7 consultation under the ESA
is not required for the issuance of an MMPA Authorization to Eglin AFB.
National Environmental Policy Act (NEPA)
In 2015, Eglin AFB provided NMFS with an EA titled Maritime Weapon
Systems Evaluation Program (WSEP) Operational Testing in the Eglin Gulf
Testing and Training Range (EGTTR), Florida. The EA analyzed the
direct, indirect, and cumulative environmental impacts of the specified
activities on marine mammals. NMFS, after review and evaluation of the
Eglin AFB EA for consistency with the regulations published by the
Council of Environmental Quality (CEQ) and NOAA Administrative Order
216-6, Environmental Review Procedures for Implementing the National
Environmental Policy Act, adopted the EA. After considering the EA, the
information in the 2014 Authorization application, and the Federal
Register notice, as well as public comments, NMFS' issuance of the 2015
Authorization and determination that the activity was not likely to
result in significant impacts on the human environment, NMFS adopted
Eglin AFB's EA under 40 CFR 1506.3; and issued a FONSI statement on
issuance of an Authorization under section 101(a)(5) of the MMPA.
In accordance with NOAA Administrative Order 216-6 (Environmental
Review Procedures for Implementing the National Environmental Policy
Act, May 20, 1999), NMFS will again review the information contained in
Eglin AFB's EA and determine whether the EA accurately and completely
describes the preferred action alternative and the potential impacts on
marine mammals. Based on this review and analysis, NMFS has reaffirmed
2015 FONSI statement on issuance of an annual authorization under
section 101(a)(5) of the MMPA.
Authorization
As a result of these determinations, NMFS has issued an Incidental
Harassment Authorization to Eglin AFB for conducting Maritime WSEP
activities, for a period of one year from the date of issuance,
provided the previously mentioned mitigation, monitoring, and reporting
requirements are incorporated.
