SUPPLEMENTARY INFORMATION:
Background
Section 101(a)(5)(E) of the Marine Mammal Protection Act (MMPA), 16
U.S.C. 1361 et seq., states that NOAA's National Marine Fisheries
Service (NMFS), as delegated by the Secretary of Commerce, shall for a
period of up to three years allow the incidental taking of marine
mammal species listed under the Endangered Species Act (ESA), 16 U.S.C.
1531 et seq., by persons using vessels of the United States and those
vessels which have valid fishing permits issued by the Secretary in
accordance with section 204(b) of the Magnuson-Stevens Fishery
Conservation and Management Act, 16 U.S.C. 1824(b), while engaging in
commercial fishing operations, if NMFS makes certain determinations.
NMFS must determine, after notice and opportunity for public
[[Page 62106]]
comment, that: (1) Incidental mortality and serious injury (M&SI) will
have a negligible impact on the affected species or stock; (2) a
recovery plan has been developed or is being developed for such species
or stock under the ESA; and (3) where required under section 118 of the
MMPA, a monitoring program has been established, vessels engaged in
such fisheries are registered in accordance with section 118 of the
MMPA, and a take reduction plan has been developed or is being
developed for such species or stock. NMFS has made a determination that
incidental taking from commercial fishing will have a negligible impact
on the endangered humpback whale, (Megaptera novaeangliae), Central
North Pacific (CNP) stock; sperm whale, (Physeter macrocephalus),
Hawaii stock; and false killer whale, (Pseudorca crassidens), MHI IFKW
stock. Recovery plans have been completed for humpback and sperm
whales, and a recovery plan has been initiated for MHI IFKW.
On June 12, 2014 (79 FR 33726), NMFS proposed to issue a permit
under MMPA section 101(a)(5)(E) to vessels registered in the Hawaii
deep-set longline fishery to incidentally take individuals from three
stocks of threatened or endangered marine mammals: The CNP stock of
humpback whales, the Hawaii stock of sperm whales, and the MHI IFKW;
and to vessels registered in the Hawaii shallow-set longline fishery to
incidentally take individuals from the CNP stock of humpback whales.
The data for considering these authorizations were reviewed coincident
with the preparation of the 2014 MMPA List of Fisheries (LOF or List)
(79 FR 14418, March 14, 2014), the 2013 marine mammal stock assessment
reports (SARs) (Carretta et al. 2014; Allen and Angliss 2014), recovery
plans for humpback and sperm whales, the False Killer Whale Take
Reduction Plan (FKWTRP), and other relevant sources. In addition, we
have also considered more recent data for false killer whales that have
not yet been incorporated into the marine mammal SARs, and a predictive
model that seeks to anticipate future fisheries interactions based on
recent changes to the fishery (the modified longline exclusion zone,
and gear modifications) that were implemented through the FKWTRP.
The vessels operating in the Hawaii deep-set and the shallow-set
longline fisheries are in the ranges of affected stocks and are
currently considered for authorization. A detailed description of these
fisheries can be found below. The Hawaii deep-set longline fishery is
the only Category I fishery under the MMPA operating around Hawaii. The
Hawaii shallow-set longline fishery is a Category II fishery; all other
Category II fisheries that may interact with the marine mammal stocks
observed off the coast of Hawaii are state-managed and are not
considered for authorization under this permit. Participants in
Category III fisheries are not required to obtain incidental take
permits under MMPA section 101(a)(5)(E) but are required to report
injuries or mortalities of marine mammals incidental to their
operations.
Basis for Determining Negligible Impact
As described above, prior to issuing a permit to take ESA-listed
marine mammals incidental to commercial fishing, NMFS must determine if
M&SI incidental to commercial fisheries will have a negligible impact
on the affected species or stocks of marine mammals. NMFS satisfied
this requirement through completion of a negligible impact
determination (see ADDRESSES). NMFS clarifies that incidental M&SI from
commercial fisheries includes M&SI from entanglement or hooking in
fishing gear. See the NID for more detailed information.
Although the MMPA does not define ``negligible impact,'' NMFS has
issued regulations providing a qualitative definition of ``negligible
impact'' for small take authorizations as defined in 50 CFR 216.103
and, through scientific analysis, peer review, and public notice,
developed a quantitative approach applied here, as ``an impact
resulting from the specified activity that cannot be reasonably
expected to, and is not reasonably likely to, adversely affect the
species or stock through effects on annual rates of recruitment or
survival'' (50 CFR 216.103). The development of the approach and
process was outlined in detail in the final NID and was included in
previous notices for other permits to take threatened or endangered
marine mammals incidental to commercial fishing (72 FR 60814, October
26, 2010 for the CNP stock of humpback whales).
Criteria for Determining Negligible Impact
In 1999, NMFS adopted criteria for making negligible impact
determinations for MMPA 101(a)(5)(E) permits (64 FR 28800; May 27,
1999). The 1999 negligible impact criteria are non-binding guidance and
do not limit NMFS' discretion to take into account additional relevant
information in determining a fishery's expected impacts on a particular
marine mammal stock. In applying the 1999 criteria to determine whether
M&SI incidental to commercial fisheries will have a negligible impact
on a listed marine mammal stock, Criterion 1 (total human-related M&SI
is less than 10% of the potential biological removal level (PBR)) is
the starting point for analysis. If this criterion is satisfied (i.e.,
total human-related M&SI is less than 10% of PBR), the analysis would
be concluded, and the impact would be determined to be negligible. If
Criterion 1 is not satisfied, NMFS may use one of the other criteria as
appropriate. Criterion 2 is satisfied if the total human-related M&SI
is greater than PBR, but fisheries-related M&SI is less than 10% of
PBR. If Criterion 2 is satisfied, vessels operating in individual
fisheries may be permitted if management measures are being taken to
address non-fisheries-related M&SI. Criterion 3 is satisfied if total
fisheries-related M&SI is greater than 10% of PBR and less than 100%
PBR, and the population is stable or increasing. Fisheries may then be
permitted subject to individual review and certainty of data. Criterion
4 stipulates that if the population abundance of a stock is declining,
the threshold level of 10% of PBR will continue to be used. Under
Criterion 5, if total fisheries-related M&SI is greater than PBR, there
is no negligible impact finding.
The time frame for this analysis primarily includes the most recent
5-year period for which available data have been processed and
incorporated into a SAR (January 1, 2007 through December 31, 2011).
The NMFS Guidelines for Assessing Marine Mammal Stocks (GAMMS) and the
subsequent GAMMS II provide guidance that, when available, the most
recent 5-year time frame of commercial fishery incidental serious
injury and mortality data is an appropriate measure of effects of
fishing operations on marine mammals (Wade and Angliss 1997). A 5-year
time frame generally provides enough data to adequately capture year-
to-year variations in take levels, while reflecting current
environmental and fishing conditions as they may change over time.
Negligible Impact Determinations
The final NID provides a complete analysis of the criteria for
determining whether commercial fisheries off Hawaii are having a
negligible impact on the stocks of CNP humpback whales, Hawaii sperm
whales, and MHI IFKW. A summary of the analysis and subsequent
negligible impact determinations follows.
[[Page 62107]]
Criterion 1 Analysis
Criterion 1 would be satisfied if the total human-related M&SI is
less than 10% of PBR. The 5-year (2007-2011) annual average M&SI to the
Hawaii stock of sperm whales from all human-caused sources is 0.7
animals, which is 6.89% of this stock's PBR of 10.2 (i.e., below the
10% of PBR threshold). Since the beginning of the NMFS Hawaii longline
observer program in 1995, no deaths of sperm whales have been
attributed to the Hawaii deep-set or shallow-set longline fishery.
However, in 2011 a sperm whale was reported seriously injured (prorated
as 0.75 serious injury) after interacting with the Hawaii deep-set
longline fishery. Two other interactions with sperm whales in 1999 and
2002 were considered non-serious injuries. Based on this low likelihood
of interactions, considered together with the lack of impacts of other
commercial fisheries and other human-caused impacts, Criterion 1 has
been met for the Hawaii stock of sperm whales. Therefore, NMFS
determines that M&SI incidental to commercial fisheries will have a
negligible impact on the Hawaii stock of sperm whales.
The 5-year (2007-2011) annual average M&SI of the CNP stock of
humpback whales from all human-caused sources is 16.2 animals, which is
26.74% of this stock's PBR of 61.2 (i.e., above the 10% of PBR
threshold). The total annual human-related M&SI for this stock of
humpback whales is not less than 10% of PBR for the time frame
considered.
The 5-year (2007-2011) annual average M&SI of the MHI IFKW stock
from all human-caused sources is estimated to be 0.1 animals, which is
33.3% of this stock's PBR of 0.3 (i.e., above the 10% of PBR
threshold). The total annual human-related M&SI for this stock of false
killer whales is not less than 10% of PBR for the time frame
considered.
Therefore, Criterion 1 was not satisfied for the CNP humpback and
MHI IFKW because the total annual human-related M&SI for each of these
two stocks is not less than 10% of PBR for each stock for the time
frame considered. As a result, other criteria must be examined for the
CNP humpback and MHI IFKW stocks.
Criterion 2 Analysis
Criterion 2 would be satisfied if the total human-related M&SI is
greater than PBR, but fisheries-related M&SI is less than 10% of PBR.
This criterion was not satisfied for either the CNP humpback or the MHI
IFKW because while total human-related M&SI (detailed above) is
believed to be less than 100% PBR for each stock, total fisheries-
related M&SI (detailed below) is greater than 10% PBR for each stock
for the time frame analyzed.
Criterion 3 Analysis
Unlike Criteria 1 and 2, which examine total human-caused M&SI
relative to PBR, Criterion 3 compares total fisheries-related M&SI to
PBR. Criterion 3 would be satisfied if the total commercial fisheries-
related M&SI (including state and federal fisheries) is greater than
10% of PBR and less than 100% PBR for each stock for the time frame
considered, and the populations of these stocks are considered to be
stable or increasing. Additionally, Criterion 3 acknowledges that there
are reasons for individually reviewing fisheries if M&SI are above PBR,
including considering information regarding any increases in permitted
M&SI and any uncertainties with regard to population size, reproductive
rates, and fisheries-related mortalities. If Criterion 3 is met,
permits may be issued subject to review and certainty of data.
The total fishery-related M&SI from all commercial fisheries for
the CNP humpback stock is estimated at 9.35 animals, or 15.3% of the
PBR (of 61.2) for the 5-year average from 2007-2011. This is greater
than 10% of PBR (6.1 animals) and less than 100% PBR (61.2 animals).
The CNP humpback whale stock has a minimum population size of 7,469 and
is estimated to be growing at a rate of up to 7% per year. A total of
0.75 humpback whales (prorated, based on NMFS' 2012 Policy on
Distinguishing Serious from Non-serious Injuries) were observed,
estimated, or assumed to have been either killed or seriously injured
in the two fisheries considered in this authorization during the 2007-
2011 time period. Accordingly, Criterion 3 is satisfied for the time
frame analyzed (2007-2011). Therefore, we determine that M&SI of the
CNP humpback whale stock incidental to commercial fishing is having a
negligible impact on the stock because of individual review of data
regarding the stock, including increased growth rate of the stock,
limited increases in M&SI due to the relevant fisheries, and the level
of fisheries-related M&SI is below the calculated PBR.
With regard to false killer whales, NMFS recognizes three stocks of
false killer whales (Hawaii pelagic, MHI insular, and Northwestern
Hawaiian Islands stocks) to be at risk of interacting with Hawaii
longline gear. Of the three stocks, only the MHI IFKW is ESA-listed.
For the Hawaii longline fisheries considered in this analysis, no MHI
IFKW deaths have been observed since the NMFS Hawaii longline observer
program began in 1995. From 2004-2012, observers recorded three false
killer whale interactions in the deep-set longline fishery and no false
killer whale interactions in the shallow-set longline fishery in the
MHI IFKW range. In the deep-set longline fishery, observers also
recorded three interactions with unidentified blackfish, which are
unidentified cetaceans known to be either a false killer whale or a
short-finned pilot whale. Genetic sampling and photo identification are
currently the only ways to distinguish MHI IFKWs from the other stocks,
and these data were not collected from the animals involved in these
interactions. In certain locations, the ranges of the MHI IFKW and
pelagic false killer whales overlap. When the stock identity of a false
killer whale hooked or entangled by the longline fisheries within the
MHI IFKW/pelagic stock overlap zone cannot be determined, NMFS prorates
the interaction to either the pelagic or MHI insular stock using a
model that assumes that densities of MHI insular stock animals decrease
and pelagic stock densities increase with increasing distance from
shore (McCracken 2010).
Based on an analysis conducted for this NID, including the
expansion from observed interactions to an estimate of fleet-wide
interactions based on the fishery's total effort and the proration of
blackfish and false killer whales of unknown stock identity (MHI IFKW
versus pelagic), we estimate that a total of 8.73 interactions occurred
with MHI IFKWs in the deep-set longline fishery from 2004-2013,
including both serious and non-serious injuries. This estimate
potentially overestimates the fishery's actual impact on MHI IFKW,
since the proration model does not account for the Northwestern
Hawaiian Islands false killer whale stock that was identified in 2011.
For example, in 2012 two observed false killer whale interactions
occurred in the area where all three Hawaiian false killer whales
stocks overlap, but at this time they can only be attributed (prorated)
to the pelagic or MHI insular stocks. In addition, earlier interaction
estimates are based on a much smaller abundance estimate for the
pelagic false killer whale stock which influences the proration model
and values.
Criterion 3 states that, where total fisheries-related M&SI are
greater than 10% PBR and less than 100% PBR, and the population is
stable or increasing, a permit may be issued subject to
[[Page 62108]]
individual review and certainty of data. As described below, NMFS
considered multiple data sets and other information in conducting this
analysis and applying Criterion 3. First, the current PBR for the MHI
IFKW is 0.3, and M&SI is estimated to be 0.1 based upon data from 2007-
2011. These data underwent NMFS and Pacific Scientific Review Group
(PSRG) review, were made available for public review and comment, and
are available in the published 2013 final SAR (Caretta et al. 2014). In
April, 2014 NMFS provided more recent data estimating abundance,
calculating a PBR, and estimating M&SI for MHI IFKW in the deep-set
fishery (the 2008-2012 timeframe) to the PSRG for review; they are
described in the final NID (see ADDRESSES). Although the 2008-2012
analyses consider more recent data with regard to MHI IFKW and previous
interactions with the fishery (compared to the 2007-2011 data presented
in the 2013 SAR), they do not take into account recent changes in the
fishery required by the FKWTRP (or Plan) regulations, nor are they
intended to anticipate future interactions in a changed fishery. In
2010, NMFS convened the False Killer Whale Take Reduction Team (FKWTRT
or Team), composed of commercial fishery representatives, conservation
groups, scientists, the Marine Mammal Commission, state and federal
officials, and other interested stakeholders, to prepare and propose a
consensus take reduction plan that, when implemented by regulations, is
expected to reduce longline fishery impacts on pelagic and MHI IFKWs to
levels below PBR within six months and to insignificant levels
approaching a zero M&SI rate (10% of PBR) over five years.
NMFS published the FKWTRP on November 29, 2012 (77 FR 71260) to
reduce the M&SI of Hawaii pelagic and MHI IFKWs in Hawaii's longline
fisheries. Measures within the Plan include gear modifications in the
deep-set longline fishery to reduce the seriousness and frequency of
injuries, reporting and captain training requirements, and area
closures, including the closure of the IFKW stock's core range to
longline fishing year-round. Specifically, the FKWTRP includes
regulatory and non-regulatory measures, including: The required use of
weak circle hooks, a minimum diameter for monofilament leaders and
branch lines, extension of the Main Hawaiian Islands Longline Fishing
Prohibited Area, annual training in mitigation techniques,
establishment of a Southern Exclusion Zone and triggers for closure,
and monitoring and reporting requirements. Most of the FKWTRP's
regulations went into effect on December 31, 2012, but gear
requirements for the deep-set longline fishery went into effect on
February 27, 2013. The measures have been in place for less than two
years, and their effectiveness is still being evaluated.
The Team is expected to meet at least annually to review the
effectiveness of the Plan and may recommend to NMFS additional measures
or changes to the Plan when warranted. NMFS anticipates that continued
implementation of the FKWTRP regulations will ensure that reduced rates
of fisheries-related M&SI of MHI IFKWs are maintained in the deep-set
longline fishery. Monitoring and reporting requirements under the
FKWTRP provide NMFS with the information necessary to prevent and
respond to any unexpected impacts. Moreover, NMFS retains its authority
under MMPA section 118(g) to issue emergency regulations and approve
amendments to the FKWTRP, in consultation with the Team, where M&SI is
having an immediate and significant adverse impact. If it is determined
that the anticipated reductions in M&SI are not being met, data
indicate that the population trajectory is declining, or the FKWTRP is
otherwise not meeting its objectives, NMFS, in consultation with the
False Killer Whale Take Reduction Team, will utilize its authority to
amend the FKWTRP regulations as necessary to ensure that the
requirements of the MMPA are met. Additionally, under such
circumstance, the NID would be re-evaluated pursuant to section
101(a)(5)(E)(iii), (iv), and (v) of the MMPA (16 U.S.C.
1371(a)(5)(E)(iii), (iv), and (v)).
While estimates of M&SI of MHI IFKW from longline fishing in the
2013 SARs (0.1 for 2007-2011) are currently below PBR (0.3), NMFS
recognizes that more recent data estimating M&SI for MHI IFKW in this
fishery (the 2008-2012 timeframe), although not yet publically
reviewed, preliminarily indicate that M&SI of MHI IFKW in this fishery
may be exceeding PBR. However, as explained above, these data do not
contemplate the significant measures taken within the Plan, which are
anticipated to reduce the deep-set longline fishery's impacts, one of
the major, known historical threats to this population, to reduce M&SI
to levels below PBR within six months and to insignificant levels
approaching a zero M&SI rate (i.e., 10% of PBR) over five years.
With these measures in mind, NMFS conducted a more recent analysis
of the likely effects of the Plan in reducing M&SI of MHI IFKW
(McCracken 2014). Aware that interactions with the deep-set longline
fishery within the range of the MHI IFKW stock were observed in 2012,
NMFS considered the 2008-2012 data in the NID analysis and included
these data in its analysis used to predict future levels of take in
this fishery. This analysis indicates that future annual M&SI for the
MHI IFKWs will remain at or below the stock's PBR level, based on
expected levels of longline fishing effort and upon implementation of
the measures within the Plan (McCracken 2014).
Regarding the population trend, although MHI IFKW abundance is
believed to have declined markedly during the 1990s, at this time, the
current population trajectory is unknown (Oleson et al. 2010).
Nevertheless, NMFS acknowledges the need for more reliable information
regarding stock trajectory, but notes that this uncertainty, along with
the presence of substantial observer coverage in this fishery, was
considered in the Team's deliberations and in the adoption of the
specific measures for minimizing the impact of the fishery on IFKWs. As
such, NMFS believes that the measures in place, coupled with the FKWTRT
process, provide a meaningful, adaptive management tool with which to
quickly monitor, identify, and respond to any unanticipated longline
fishery impacts to the MHI IFKW population.
NMFS acknowledges that interactions with non-longline fisheries may
be occurring, and continues to work cooperatively with the State of
Hawaii and other partners to assess marine mammal interactions in
state-managed fisheries. NMFS will continue to consult with the Hawaii
Department of Land and Natural Resources to improve data collection in
these fisheries.
To summarize, Criterion 3 is satisfied if total fisheries related
M&SI is greater than 10% of PBR and less than 100% PBR, and the
population is stable or increasing. Fisheries may then be permitted
subject to individual review and certainty of data. The current PBR for
the MHI IFKW is 0.3, while estimates of M&SI from longline fishing are
a fraction below PBR (i.e., between 10% and 100% of PBR). While
estimates of M&SI of MHI IFKW from longline fishing in the 2013 SAR
(2007-2011) are currently below PBR, NMFS recognizes that more recent
data estimating M&SI for MHI IFKW in this fishery (the 2008-2012
timeframe), although not yet publically reviewed, preliminarily
indicate that M&SI of MHI IFKW in this fishery may be exceeding PBR.
NMFS considered the 2008-2012 data in the
[[Page 62109]]
NID and included these data in its analysis used to predict future
levels of take in this fishery. This analysis indicates that future
annual M&SI for the MHI IFKW will remain at or below the stock's PBR
level, based on expected levels of longline fishing effort and upon
implementation of the measures within the Plan. Although NMFS has
historic information of a larger IFKW population, it does not currently
have sufficient information with which to reliably determine whether
the current population is stable or increasing. NMFS acknowledges the
need for more reliable information regarding stock trajectory, but
notes that this uncertainty, along with the presence of substantial
observer coverage in this fishery, was considered in the FKWTRT's
deliberations and in the adoption of the specific measures for
minimizing the impact of the fishery on IFKWs. NMFS retains its
authority under MMPA section 118(g) to issue emergency regulations and
approve amendments to the FKWTRP, in consultation with the FKWTRT,
where M&SI is having an immediate and significant adverse impact.
Additionally, under such circumstance, the NID would be re-evaluated
pursuant to section 101(a)(5)(E)(iii), (iv), and (v) of the MMPA (16
U.S.C. 1371(a)(5)(E)(iii), (iv), and (v)). Accordingly, NMFS is
satisfied that under the FKWTRT process, the longline fishery will have
a negligible impact on the MHI IFKW.
In conclusion, based on the negligible impact criteria outlined in
1999 (64 FR 28800), the 2013 Alaska and Pacific SARs (Allen and Angliss
2014; Carretta et al. 2014), the FKWTRP, the predictive model, and the
best scientific information and data available, NMFS has determined
that for a period of up to three years, M&SI incidental to the Hawaii
deep-set longline fishery and Hawaii shallow-set longline fishery will
have a negligible impact on the CNP stock of humpback whales, the
Hawaii stock of sperm whales, and the MHI insular stock of false killer
whales. Therefore, vessels operating in these identified commercial
fisheries within the range of the CNP humpback, Hawaii sperm whale, and
MHI IFKW stocks may be permitted subject to their individual review and
the certainty of relevant data, and provided that the other provisions
of section 101(a)(5)(E) are met.
Description of Fisheries
The Hawaii deep-set and shallow-set longline fisheries are the
Federally-authorized fisheries classified as Category I and II in the
2014 LOF (NMFS 2014) that are known to seriously injure or kill ESA-
listed marine mammals incidental to commercial fishing operations.
Detailed descriptions of those fisheries can be found in the Final
Biological Opinion on the continued operation of the Shallow-set
Longline Swordfish fishery, dated January 30, 2012 (NMFS 2012a); the
2013SARs (Carretta et al. 2014, Allen and Angliss 2014); and the final
NID.
In accordance with MMPA section 118(c), only those vessels in the
Hawaii deep-set and shallow-set longline fisheries that have registered
for a Marine Mammal Authorization Permit are authorized to take marine
mammals incidental to their fishing operations. Vessels holding this
permit must comply with the FKWTRP and implementing regulations. The
longline fisheries are limited access fisheries, with 164 transferable
permits of which approximately 130 are currently active. Vessels active
in these fisheries are limited to 101 ft in length. Hawaii-based
longline vessels vary their fishing grounds depending on their target
species. Most effort is to the north and south of the Hawaiian Islands
between the equator and 40[deg] N and longitudes 140[deg] and 180[deg]
W; however, the majority of deep-set fishing occurs south of 20[deg] N
and the majority of shallow-set fishing occurs north of 20[deg] N. The
number of active vessels in the combined Hawaii-based deep-set and
shallow-set longline fishery increased dramatically in the late 1980s
and peaked at 141 vessels in 1991. The number of vessels in the
combined longline fisheries has since ranged from 101 to 130. In 2011,
129 Hawaii-based longline vessels were active in the deep-set longline
fishery. The deep-set longline fishery operates year-round, although
vessel activity increases during the fall and is greatest during the
winter and spring months. The annual number of trips for the Hawaii-
based longline fisheries has remained relatively stable, but there was
a shift from mixed-target and swordfish-target trips to tuna-target
trips from the early 1990s up to 2002. In the years 2000-2003, this
shift reflected the regulatory closure of the shallow-set and mixed-
target fisheries. In 2004, the shallow-set longline fishery was
reopened but participation was limited to only six trips. In 2011,
there were 1,388 combined longline trips (1,306 deep-set and 182
shallow-set), which resulted in a combined total of 18,623 sets (17,155
deep-set and 1,468 shallow-set). Effort in the combined longline
fishery, measured by the number of hooks set, has ranged from
approximately 39 to 42 million hooks per year from 2007-2011.
Conclusions for Permit
Based on the above assessment and as described in the accompanying
NID, NMFS concludes that the incidental M&SI from vessels engaged in
the Hawaii deep-set and shallow-set fisheries will have a negligible
impact on the CNP stock of humpback whales, the Hawaii stock of sperm
whales, and the MHI insular stock of false killer whales. The National
Environmental Policy Act (NEPA) requires Federal agencies to evaluate
the impacts of alternatives for their actions on the human environment.
The impacts on the human environment of continuing the Hawaii deep-set
and shallow-set longline fisheries, including the taking of threatened
and endangered species of marine mammals, were analyzed in the
Regulatory Amendment to the Western Pacific Pelagic Fishery Ecosystem
Plan: Revised Swordfish Trip Limits in the Hawaii Deep-set Longline
Fishery to Reduce Regulatory Discards with an Environmental Assessment
(NMFS and WPFMC 2012); the False Killer Whale Take Reduction Plan
Environmental Assessment (NMFS 2012b); Amendment 18 to the Pelagics FMP
and Final SEIS (NMFS and WPFMC 2009); Amendment 7 to the Pelagics FEP
and Environmental Assessment (NMFS 2014a), and in the Final Biological
Opinion prepared for the Hawaii shallow-set longline fishery (NMFS
2012a) and the Final Biological Opinion for the Hawaii deep-set
longline fishery (NMFS 2014b), pursuant to the ESA. NMFS has prepared a
record of environmental consideration that concludes that because this
proposed permit would not modify any fishery operation and the effects
of the fishery operations have been evaluated fully in accordance with
NEPA, no additional NEPA analysis is required for this permit. Issuing
the proposed permit would have no additional impact to the human
environment or effects on threatened or endangered species beyond those
analyzed in these documents.
Recovery Plans
Recovery Plans for humpback whales and sperm whales have been
completed (see http://www.nmfs.noaa.gov/pr/recovery/plans.htm#mammals).
A Recovery Plan has been initiated for the MHI IFKW (78 FR 60850,
October 2, 2013). Accordingly, the requirement to have recovery plans
in place or being developed is satisfied.
[[Page 62110]]
Vessel Registration
MMPA section 118(c) requires that vessels participating in Category
I and II fisheries register to obtain an authorization to take marine
mammals incidental to fishing activities. Further, section 118(c)(5)(A)
provides that registration of vessels in fisheries should, after
appropriate consultations, be integrated and coordinated to the maximum
extent feasible with existing fisher licenses, registrations, and
related programs. Registration for the Hawaii longline fisheries has
been integrated into the existing permit process, and all permitted
participants in the Hawaii deep-set and shallow-set longline fisheries
are issued annual Marine Mammal Authorization Program certificates with
their new or renewed permits. Therefore, vessel registration for an
MMPA authorization is integrated through those programs in accordance
with MMPA section 118.
Monitoring Program
The Hawaii longline fisheries have been observed by NMFS observers
since the mid-1990s. Levels of observer coverage vary over time but are
adequate to produce reliable estimates of M&SI of ESA-listed species.
From 2002-2013, observer coverage was greater than 20% in the deep-set
longline fishery and has been 100% in the shallow-set longline fishery
since 2004. Accordingly, as required by MMPA section 118, a monitoring
program is in place for both fisheries.
Take Reduction Plans
Subject to available funding, MMPA section 118 requires the
development and implementation of a Take Reduction Plan (TRP) when a
strategic stock interacts with a Category I or II fishery. The three
stocks considered for this permit are currently designated as strategic
stocks under the MMPA because they are listed as endangered under the
ESA (MMPA section 3(19)(C)).
In 2010, NMFS established the FKWTRT to develop a TRP to address
the incidental M&SI of Hawaii pelagic and MHI IFKWs in the Hawaii-based
deep-set and shallow-set longline fisheries. The FKWTRP was
implemented, through regulations, in November 2012 (77 FR 71260). The
short- and long-term goals of a TRP are to reduce M&SI of marine
mammals incidental to commercial fishing to levels below PBR within six
months and to insignificant levels approaching a zero M&SI rate (i.e.,
10% of PBR) within five years. MMPA section 118(b)(2) states that
fisheries maintaining insignificant levels of M&SI are not required to
further reduce their M&SI rates.
The CNP stock of humpback whales and the Hawaii stock of sperm
whales are also strategic stocks that interact with the Hawaii longline
fisheries. However, the obligations to develop and implement a TRP are
subject to the availability of funding. MMPA section 118(f)(3) (16
U.S.C. 1387(f)(3)) contains specific priorities for developing TRPs
when funding is insufficient to develop and implement TRPs for all
strategic stocks and Category I and II fisheries. NMFS has insufficient
funding available to simultaneously develop and implement TRPs for all
stocks that interact with Category I or Category II fisheries. NMFS
used the most recent SARs and LOF as the basis to determine its
priorities for establishing TRTs and developing TRPs. Through this
process, NMFS evaluated the Hawaii stock of sperm whales and the CNP
stock of humpback whales and the Hawaii longline fisheries and
identified these as lower priorities compared to other marine mammal
stocks and fisheries for establishing TRTs, based on M&SI levels
incidental to those fisheries and population levels and trends.
Accordingly, given these factors and NMFS' priorities, further
developing TRPs for the Hawaii stock of sperm whale and the CNP stock
of humpback whales in the Hawaii longline fishery will be deferred
under section 118 as other stocks/fisheries are a higher priority for
any available funding for establishing new TRTs.
As noted in the summary above, all of the requirements to issue a
permit to vessels that operate in the Federally-authorized Hawaii deep-
set and shallow-set longline fisheries have been satisfied.
Accordingly, NMFS hereby issues a permit to participants in the
Category I Hawaii deep-set longline fishery for the taking of CNP
humpback whales, Hawaii sperm whales, and MHI IFKWs, and to the
Category II Hawaii shallow-set longline fishery for the taking of CNP
humpback whales incidental to the fisheries' operations. As noted under
MMPA section 101(a)(5)(E)(ii), no permit is required for vessels in
Category III fisheries. For incidental taking of marine mammals to be
authorized in Category III fisheries, any injuries or mortality must be
reported to NMFS. If NMFS determines at a later date that incidental
mortality and serious injury from commercial fishing is having more
than a negligible impact on the CNP humpback whales, Hawaii sperm
whales, or MHI IFKW stocks, NMFS may use its emergency authority under
MMPA to protect the stock and may modify the permit issued herein, and
re-evaluate the NID.
MMPA section 101(a)(5)(E) requires NMFS to publish in the Federal
Register a list of fisheries that have been authorized to take
threatened or endangered marine mammals. A list of such fisheries was
most recently published on September 4, 2013 (78 FR 54553), which
authorized the taking of threatened or endangered marine mammals
incidental to the California thresher shark/swordfish drift gillnet
fishery and the Washington/Oregon/California sablefish pot fishery.
With issuance of the current permit, NMFS is not adding any fisheries
to this list (Table 1).

Comments and Responses
On June 12, 2014 (79 FR 33726), NMFS proposed to issue a permit
under MMPA section 101(a)(5)(E) to vessels registered in the Hawaii
deep-set longline fishery to incidentally take individuals from three
stocks of threatened or endangered marine mammals: The CNP stock of
humpback whales, the Hawaii stock of sperm whales, and the MHI insular
stock of false killer whales; and to vessels registered in the Hawaii
shallow-set longline fishery to incidentally take individuals from the
CNP stock of humpback whales. NMFS solicited comments on the proposal
to issue a permit and the negligible impact determination and received
comments from the Marine Mammal Commission (Commission); non-
governmental organizations (The Humane Society of the United States
(HSUS) on behalf of themselves and the National Resources Defense
Council (NRDC); Earthjustice on behalf of the Center for Biological
Diversity and Turtle Island Restoration Network; Cascadia Research
Collective (CRC); the Hawaii Longline Association (HLA)); the Western
Pacific Regional Fisheries Management Council (Council); and three
individuals. Most letters contained multiple comments. NMFS received
comments both in support of and in opposition to the negligible impact
determination and proposed permit. Two commenters supported the
determinations for all three species, while several other commenters
supported the determinations only for humpback whales and sperm whales.
There were no comments in opposition to the negligible impact
determinations or issuance of a permit for the incidental take of
individual CNP humpback whales and Hawaii sperm whales. All comments in
opposition to the issuance of a permit were specific to the deep-set
fishery and MHI IFKW. These comments are addressed in detail below.
Comment 1: HLA asked NMFS to clarify how the agency has applied the
1999 negligible impact determination criteria, specifically to the MHI
IFKW stock. HLA also recommended that NMFS explain its consideration of
future M&SI impacts for MHI IFKW in light of the enactment of the
FKWTRP regulations.
Response: NMFS believes that the rate of MHI IFKW M&SI is expected
to decrease in response to the FKWTRP regulations, based upon a
predictive model to account for the expected impact of the longline
fishery on marine mammals. There is only one complete year of data
since the FKWTRP regulations went into effect, and much of the data
that have been collected have not yet been fully analyzed (e.g., injury
determinations, bycatch estimates, etc.). When evaluating the deep-set
longline fishery's expected impacts on the IFKW, we relied on
historical M&SI since it represents the best available information,
recognizing that the data were collected prior to the implementation of
FKWTRP measures intended to mitigate the fishery's impacts on false
killer whales. For example, the recently discovered NWHI stock of IFKW
was not accounted for in historic M&SI estimates, which were
necessarily prorated only between the MHI insular and pelagic false
killer whale stocks.
In preparing its analysis in the predictive model, NMFS took
several steps to account for the changes under the FKWTRP regulations.
For example, the predictive model incorporated the revised boundary of
the MHI Longline Fishing Prohibited Area, and described our expectation
of further reductions in M&SI due to other FKWTRP measures (gear
regulations requiring the use of weak circle hooks and strong
branchlines to allow for the release of the animal with reduced
trailing gear and risk of injury). We also noted that the model's
predicted level of M&SI was based on historical interactions that
occurred in an area that, under the FKWTRP regulations, is now closed
to longline fishing year-round. At this time, given the defined range
of the IFKW stock, NMFS cannot conclude that the closure of this
seasonal boundary will eliminate all risk of future fisheries-related
M&SI to the stock, but we do believe that future M&SI will be extremely
rare, on the order of only one animal every four years.
With regard to NMFS consideration of the 1999 negligible impact
determination criteria, NMFS utilized Criterion 3 for MHI IFKW.
Criterion 3 states that, where total fisheries-related M&SI are greater
than 10% PBR and less than 100% PBR, and the population is stable or
increasing, fisheries may be permitted subject to individual review and
certainty of data. NMFS considered multiple data sets and other
information in conducting this analysis and applying Criterion 3 in the
case of the MHI IFKW. The 1999 criteria were intended to guide NMFS in
its evaluation of fishery impacts on marine mammal stocks, while
allowing NMFS to exercise discretion, through the use of notice and
comment in the permitting process and to take into account additional
relevant information in
[[Page 62112]]
determining a fishery's expected impacts on a particular marine mammal
stock. In this case, NMFS convened the FKWTRT, composed of commercial
fishery representatives, conservation groups, scientists, state and
federal fishery resource management officials, the Commission, and
other interested stakeholders, to prepare a consensus FKWTRP that, when
implemented by regulations, would be expected to reduce longline
fishery impacts on pelagic and MHI IFKWs to less than PBR within six
months and to insignificant levels approaching a zero mortality and
serious injury rate (i.e., less than ten percent) of their respective
PBR levels within five years of the plan implementation. As noted
above, measures addressing the MHI IFKW include gear modifications to
reduce the seriousness and frequency of injuries, reporting and captain
training requirements, and area closures, including the closure of the
MHI IFKW stock's core range. This Team is expected to meet at least
annually to review the effectiveness of the Plan, and may recommend to
NMFS additional measures or changes to the Plan when warranted.
The current PBR for the MHI IFKW is 0.3; estimates of M&SI from
longline fishing are a fraction below PBR. Both PBR and M&SI are
extremely small numbers, indicative of both the IFKW's small population
size, as well as the fishery's low impact rate. Although NMFS has
historic information of a larger IFKW population, it does not currently
have sufficient information with which to reliably determine whether
the current population is stable or increasing. NMFS acknowledges the
need for more reliable information regarding stock trajectory, but
notes that this uncertainty, along with the presence of substantial
observer coverage in this fishery, was considered in the FKWTRT's
deliberations and in the adoption of the specific measures for
minimizing the impact of the fishery on IFKWs. Nevertheless, NMFS does
have reliable information regarding the longline fishery's impacts on
that stock and believes that the FKWTRT process provides a useful
adaptive management tool with which to quickly monitor, identify, and
respond to unanticipated longline fishery impacts to the IFKW
population. Moreover, NMFS retains its authority under MMPA section
118(g) to issue emergency regulations and approve amendments to the
FKWTRP, in consultation with the FKWTRT, where M&SI is having an
immediate and significant adverse impact. Additionally, should it be
determined that M&SI of MHI IFKW are having an adverse impact on the
stock, the negligible impact determination would be re-evaluated
pursuant to section 101(a)(5)(E)(iii), (iv), and (v) of the MMPA (16
U.S.C. 1371(a)(5)(E)(iii), (iv), and (v)).
Comment 2: HSUS and Earthjustice commented that although the 2007-
2011 data (in the 2013 SAR) indicate that MHI IFKW M&SI is less than
PBR, the preliminary data for 2008-2012 (contained in the draft 2014
SAR, currently under internal agency review) indicate that M&SI exceeds
PBR. Earthjustice emphasized that because M&SI of MHI IFKW were
observed in 2011 and 2012, and NMFS reports bycatch estimates as 5-year
running averages, PBR will continue to be exceeded in future SARs,
rather than below PBR, as NMFS predicted in the draft NID and proposed
permit.
Response: The NID analysis relies primarily on data from 2007-2011
because they are the most recent data that have gone through the MMPA
review process and are available in a published SAR (the 2013 SAR).
More recent data (the 2008-2012 timeframe) have been provided to the
Pacific Scientific Review Group for review but have not yet been made
available for public review and comment as a draft SAR. We recognize
that interactions with the deep-set longline fishery within the range
of the MHI IFKW stock were observed in 2012 and will be reported in the
draft 2014 SAR, and the 5-year average M&SI rate calculated in the SAR
will account for those interactions. We considered the 2008-2012 data
in the NID analysis and incorporated those data into the model to
predict future levels of take (McCracken 2014); this model indicates
that future annual M&SI for the MHI IFKWs will remain at or below the
stock's PBR level, based on expected levels of longline fishing effort
and upon implementation of the measures within the Plan.
Consistent with the application of the 1999 negligible impact
determination criteria, NMFS may exercise our discretion under MMPA to
take into account other relevant information, including the predictive
model, when deciding whether to issue the permit. The M&SI referred to
by the commenter occurred in an area to the north of the MHI, which is
now closed to longline fishing year-round under the expanded MHI
Longline Prohibited Area, as unanimously recommended by the FKWTRT and
implemented by NMFS through the FKWTRP regulations. Moreover, as more
fully described in the NID, M&SI for MHI IFKWs is expected to be
further reduced in response to a suite of mitigation measures contained
in the FKWTRP, including gear requirements, the Southern Exclusion Zone
trigger/closure, and captain training and reporting requirements, which
went into effect in early 2013. Finally, preliminary observer data
indicate there were no false killer whale interactions observed within
range of the MHI IFKW stock in 2013 or in 2014 to date, which is
consistent with the results of the predictive model. Accordingly, NMFS
believes that the predictive model, which better accounts for these
changes to the fishery, provides the more reliable estimate of
fisheries-related M&SI. NMFS expects the implementation of consensus
measures that are specifically intended to address impacts on MHI IFKW,
with the commitment to re-evaluate the NID, if warranted, is sufficient
to support issuance of the NID.
Comment 3: HLA asserted that there has never been a documented
interaction between the Hawaii longline fisheries and MHI IFKWs,
despite high observer coverage and substantial genetic sampling of
incidentally taken false killer whales. In addition, HLA cites NMFS'
statement that there are ``no documented serious injuries or
mortalities of [MHI IFKW stock] animals incidental to Hawaii's longline
fisheries'' (75 FR 2853, January 19, 2010).
Response: The draft NID and its conclusions regarding M&SI of MHI
IFKW are based on the final 2013 and preliminary draft 2014 Pacific
SARs (which document past M&SI) and predictive modeling (which
evaluates expected future M&SI by the fishery). The SARs, the
predictive model, and the references cited therein provide information
on the data and methods used in assessing and estimating M&SI of MHI
IFKW, including the associated assumptions and uncertainties.
In evaluating potential impacts to MHI IFKW, NMFS accounted for
uncertainty in stock identification when interactions occur, as well as
data limitations based on observer coverage rates (generally 20% in the
deep-set longline fishery). NMFS recognizes that although the FKWTRP
regulations are expected to reduce the potential for impacts to the MHI
IFKW to less than PBR within six months and to insignificant levels
approaching a zero mortality and serious injury rate (i.e., less than
ten percent) of their respective PBR levels within five years of the
plan implementation, we cannot eliminate all risk of M&SI to the stock.
MHI IFKW and pelagic false killer whales cohabit a considerable area
referred to as the
[[Page 62113]]
``overlap zone''. As noted in the SARs and the NID, interactions
between the deep-set longline fishery and false killer whales and
blackfish (unidentified cetaceans known to be either false killer
whales or short-finned pilot whales) have been observed within the MHI
insular/pelagic stock overlap zone. Genetic sampling and photo
identification are currently the only ways to distinguish MHI insular
from pelagic false killer whales; and, because of challenging sampling
conditions, these data were not collected from the animals involved in
the interactions observed within the MHI insular/pelagic stock overlap
zone.
When takes cannot be affirmatively identified to a particular
stock, they are subject to proration using peer-reviewed criteria that
account for each stock's population and relative density. Takes of
unidentified blackfish are prorated to each species, and false killer
whales of unknown stock in the MHI insular/pelagic stock overlap zone
are prorated to one stock or the other, based on various models
(McCracken 2010). The assignment of take within the MHI insular/pelagic
overlap zone is supported by GAMMS II. NMFS believes that proration is
currently the best method for determining impacts among different
stocks, given the challenges associated with making positive
identifications of stock, and in accounting for impacts to all stocks.
Finally, the reference to the NMFS statement, ``no documented
serious injuries or mortalities of [MHI IFKW stock] animals incidental
to Hawaii's longline fisheries,'' omits an entire sentence from the
Federal Register notice, which states that the provided information
comes from the 2008 and 2009 SARs. These SARs became final prior to
reevaluation of the insular stock boundary and the establishment of the
MHI insular/pelagic overlap zone and do not always necessarily
represent the best available scientific and commercial information.
Comment 4: HLA and the Council commented that the current MHI IFKW
stock boundary (uniform 140 km from the MHI) is overinflated, given
satellite tagging data that indicate different movement patterns
between leeward and windward sides of the MHI, and a maximum distance
from shore of 51.4 km on the windward side. HLA stated that additional
analysis by NMFS has led the agency to conclude that the currently
defined range is overbroad.
Response: In the draft NID, NMFS identified the satellite tagging
information suggestive of a reduced range of the MHI IFKW (from shore
of 51.4 km) on the windward side of the MHI. In our analysis, we
applied this information qualitatively along with other relevant
information to support our conclusion that the predictive model
represents the maximum impact of the longline fishery that is
reasonably likely to occur, and that actual impacts likely would be
less. However, the data referred to by HLA represent an incomplete
subset of available information on the MHI IFKW movements, and they are
currently being reviewed to help inform the decision whether to revise
the boundaries for several Hawaii false killer whale stocks. At this
time, NMFS has not yet completed this review as part of the stock
assessment process, and revised boundaries, if any, have not yet been
determined. Accordingly, NMFS will continue to rely on the established
stock boundaries for this NID analysis, while taking into account new
satellite tagging information where relevant to our management
decisions.
Comment 5: HLA recommended that NMFS reevaluate the historical
(pre-2013) M&SI data in light of the new information on the MHI IFKW
stock's range (described in Comment 4). HLA and the Council noted that
all historical M&SI attributed to the MHI IFKW stock occurred on the
windward side of the MHI beyond where MHI IFKWs have been observed or
tracked. Given this information, HLA argues that the retrospective M&SI
rate would be zero.
Response: As explained in the response to Comment 4, NMFS took into
account the new satellite tagging information, along with other
relevant information, in determining that the predictive model
represents the maximum impact of the longline fishery that is
reasonably likely to occur. This information is currently being
reviewed to help inform the decision whether to revise the boundaries
for several Hawaii false killer whale stocks.
Comment 6: HLA and the Council commented that the FKWTRP modified
the existing MHI longline fishing prohibited area to eliminate the
spatial overlap between MHI IFWKs and the longline fisheries, thereby
eliminating the potential for MHI IFKW interactions with the longline
fisheries. They note that modified year-round closure encompasses the
locations of all false killer whale interactions assigned to the MHI
IFKW stock, as well as all areas where MHI IFKWs have been observed or
tracked. Therefore, the fishery is not likely to adversely affect the
MHI IFKW.
Response: The revision to the longline closure area is an important
conservation measure to protect MHI IFKWs. However, as noted in FKWTRP
final rule (77 FR 71260, November 29, 2012; comment/response 39) and
IFKW ESA listing final rule (77 FR 70915, November 28, 2012; comment/
response 13), the Plan's revision to the longline exclusion zone is
expected to substantially reduce but not eliminate the risk of
interactions between MHI IFKWs and the longline fisheries. MHI IFKWs,
like all small cetaceans, are highly mobile and do not confine their
movements within precise boundaries. Because a portion of the MHI
insular/pelagic stock overlap zone, as it is currently defined, remains
open to longline fishing, NMFS must account for the potential for
future M&SI in its management decisions, rare as those interactions are
expected to be. Although NMFS does not agree that the MHI longline
fishing prohibited area eliminates all risk to the MHI IFKW, we believe
that M&SI for MHI IFKW will occur at very low levels as determined in
the NID, and therefore is not likely to jeopardize the continued
existence of MHI IFKW as defined under the ESA (see Comment 11, below).
We have accounted for the revision to the MHI longline fishing
prohibited area and its associated conservation benefits in our
predictive model.
Comment 7: CRC, HSUS, Earthjustice, and the Commission commented
that the NID does not account for M&SI in fisheries other than the
longline fisheries. The commenters assert that MHI IFKW interactions
with non-longline fisheries may be occurring at a rate that exceeds
PBR. Commenters provided the following arguments or information: (a)
Interactions with commercial fisheries were identified as a main threat
to the MHI IFWK population in NMFS's 2010 status review; (b) non-
longline fisheries are unmonitored, so marine mammal interactions are
unreported or under-reported; (c) marine mammal depredation has been
reported in nearshore (non-longline) fisheries; (d) a stranded MHI IFKW
was shown to have ingested fishing hooks not used by the longline
fisheries; (e) MHI IFKWs have scarring and fin disfigurements
consistent with fisheries interactions, and the individual rate of
fisheries interactions (based on scarring) for MHI IFKWs may exceed
that for pelagic false killer whales, where M&SI is known to exceed
PBR; (f) the apparent sex bias in the animals with fisheries-related
scarring (all females) suggests that M&SI estimates may be negatively
biased and may have a disproportionate impact on population dynamics;
and (g) fisheries-related scarring does not occur with equal frequency
in the three MHI IFKW social clusters, and there are coincident
[[Page 62114]]
differences in survival rates for each cluster, so impacts by social
cluster could have greater or lesser impact on the stock.
Response: NMFS recognizes that the NID may not account for all
potential sources of M&SI, including unreported takes in fisheries
other than Hawaii longline fisheries. However, the Hawaii longline
fishery currently operates under a consensus FKWTRP that was
specifically designed to reduce the longline fisheries' M&SI for
pelagic and MHI IFKW to less than PBR within six months and to
insignificant levels approaching a zero mortality and serious injury
rate (i.e., less than ten percent) of their respective PBR levels
within five years of the plan implementation in the Hawaii longline
fisheries. Other coastal fisheries, including state-managed pelagic
troll, kaka line, and short-line, as well as recreational fisheries,
are not currently observed, and NMFS has received no self-reports from
these fisheries of interactions with marine mammals. At present, the
impacts of these fisheries on MHI IFKW have not been reliably
documented. The State of Hawaii currently collects commercial fishing
information on depredation but not marine mammal interactions (i.e.
hooking and entanglements). This information has limited usefulness for
evaluating impacts to marine mammals. However, NMFS continues to
consult with the State of Hawaii and other partners to assess and
address marine mammal interactions in state-managed fisheries. Data
collection on marine mammal interactions in state fisheries has been
identified as a research priority by the Team. NMFS and the State of
Hawaii have updated their existing ESA Section 6 Cooperative Agreement
to include the MHI IFKW. Additionally, the State of Hawaii intends to
submit a proposal for federal funding in response to the recent ESA
Section 6 Federal Funding Opportunity that would address priority
recovery actions for the MHI IFKW. NMFS will continue to work with the
Hawaii Department of Land and Natural Resources within available budget
and resource constraints to improve data collection in these fisheries.
With regard to the commenters pointing to specific examples of fin
disfigurement, scarring, and hook ingestion to support an argument that
fisheries impacts are occurring above and beyond those occurring from
longline fishing, NMFS considered this information in its decision to
list the MHI IFKW distinct population segment as an endangered species
under the ESA. While NMFS shares the commenters' concerns as to what
these incidents may mean to the species, it remains undetermined as to
whether the observations of fin scarring would be deemed serious
injuries, and if so, whether fishing hook ingestion caused M&SI of MHI
IFKW.
In summary, in the absence of available information regarding the
potential impacts of other fisheries on MHI IFKW, NMFS cannot determine
their contribution to total fisheries-related M&SI. NMFS is basing its
decision to issue the permit under Criterion 3, where known longline
fishing M&SI is between 10% and 100% of PBR, and due to the fact that
the longline fishery is subject to management under a consensus FKWTRP
that is intended to reduce longline impacts on MHI IFKW to levels below
PBR within six months and to insignificant levels approaching a zero
mortality and serious injury rate (i.e., less than ten percent) of
their respective PBR level within five years of the plan
implementation. NMFS remains concerned about the anecdotal evidence
that MHI IFKW are interacting with other fisheries, and, therefore,
NMFS is committed to working with the State of Hawaii and others to
assess the frequency and severity of marine mammal interactions in
state-managed fisheries, as well as the distribution of these
interactions and how they may disproportionately affect different sexes
or social clusters. Further, NMFS commits to working with the State of
Hawaii and other partners at further reducing impacts to IFKW as
appropriate.
Comment 8: CRC and one individual commented that NMFS did not
account for contaminants as a source of human-caused M&SI in MHI IFKWs.
CRC cited several papers and provided data showing that concentrations
of persistent organic pollutants in individual MHI IFKWs exceed safe
threshold concentrations, and suggested that high levels of persistent
organic pollutants may have health impacts and thus potentially
contribute to mortality.
Response: NMFS recognizes that contaminants may present a non-
fisheries related threat to MHI IFKWs (e.g., Oleson et al., 2010). NMFS
is concerned about MHI IFKW exposure to persistent organic pollutants
in particular; however, at present it is difficult to determine the
contribution of contaminants on M&SI in MHI IFKWs. Within the timeframe
analyzed for this NID, no mortalities of MHI IFKWs were attributed to
acute contaminants exposure (Carretta et al. 2014). At this time, it
remains unclear what effect chronic exposure to contaminants may be
having on IFKW individuals and population health. Frequently, however,
marine mammals are exposed to chronic low levels of contaminants and
these chronic exposures can be extremely difficult to correlate to
risks of M&SI or reproductive health and population survival.
Comment 9: CRC, HSUS, Earthjustice, and the Commission commented
that the MHI IFKW M&SI data are uncertain, specifically in the
prediction of M&SI in the longline fisheries and in accounting for M&SI
in non-longline fisheries. The Commission suggested that the level of
uncertainty in M&SI data, particularly for a stock with a PBR less than
one animal per year, should be grounds for withholding issuance of the
permit.
Response: NMFS acknowledges the uncertainty associated with the
data. As more fully discussed above, NMFS' predictions account for data
uncertainty by applying precautionary assumptions at various levels of
the NID analysis. Although PBR for this stock is quite small, so is
quantifiable M&SI from the longline fishery, and M&SI from longline
fishing is based on prorated interactions that occurred in an area that
is now permanently closed to longlining. Moreover, as more fully
discussed in response to Comment 2, M&SI for the longline fishing is
based on historical interaction data, collected prior to implementation
of consensus FKWTRP measures that are specifically intended to reduce
longline impacts on false killer whales to less than PBR within six
months and to insignificant levels approaching a zero mortality and
serious injury rate (i.e., less than ten percent of their respective
PBR levels) within five years of the plan implementation. In addition,
preliminary data indicate no M&SI for MHI IFKW in 2013 or in 2014 to
date. Finally, under the adaptive management provisions of the FKWTRP
and MMPA section 118(g), NMFS retains authority to amend the Plan, and
implement emergency measures, should unanticipated impacts from the
deep-set fishery threaten the conservation status of the MHI IFKW.
Additionally, the negligible impact determination would be re-evaluated
pursuant to section 101(a)(5)(E)(iii), (iv), and (v) of the MMPA (16
U.S.C. 1371(a)(5)(E)(iii), (iv), and (v)). Based on these
considerations, NMFS believes that it is appropriate to issue the
permit, notwithstanding the existence of some uncertainty in fishery-
related M&SI.
Comment 10: Earthjustice stated that NMFS provides no justification
for its claim that the use of new gear under the
[[Page 62115]]
FKWTRP would reduce false killer whale M&SI by 6%.
Response: The FKWTRT, which consisted of conservation organization
representatives, biologists, federal and state officials, the
Commission, and fishing industry representatives, unanimously
recommended the requirement for weak circle hooks based on their
collective professional judgment that these hooks would reduce both the
frequency and severity of incidental interactions with false killer
whales. The NID considers Forney et al. (2011) as the source of the
predicted 6% reduction in false killer whale M&SI associated with the
exclusive use of circle hooks in the deep-set fishery. This estimate is
the best available information regarding the expected benefits of these
hooks.
Comment 11: The HSUS stated that a 2013 analysis of the biological
impacts of the deep-set longline fishery by the Sustainable Fisheries
Division of the NMFS Pacific Islands Regional Office concluded that the
prorated level of M&SI of the MHI IFKW population incidental to the
deep-set fishery (0.5 animals per year) exceeds the stock's PBR level
of 0.3 animals per year, and that the longline fishery alone ``may
affect and is likely to adversely affect'' the insular stock of false
killer whales.
Response: The analysis cited by HSUS appears in the Biological
Evaluation that was submitted to the NMFS Pacific Islands Regional
Office Protected Resources Division from the Sustainable Fisheries
Division in order to initiate formal consultation under Section 7 of
the ESA on the continued authorization of the Hawaii deep-set longline
fishery. The Sustainable Fisheries Division included information from
the most recent SAR available to the public at that time (2012 SAR,
which included data from 2006-2010) to be incorporated into the ESA
Section 7 Biological Opinion analysis. During the consultation period
and the analysis for the NID, more recent data, including the
predictive model, became available and were used in both the MMPA and
ESA analyses.
As more fully discussed in the response to Comment 1, the M&SI
estimates cited by the commenter are based on historical data that
preceded implementation of the FKWTRP regulations. To reach this NID
NMFS believed it appropriate to consider not only historical M&SI
information, but also other information that may affect the
conservation status of the stock, such as the measures included in the
FKWTRP, and the predictive model.
The Sustainable Fisheries Division's analysis that the fishery
``may affect and is likely to adversely affect'' the MHI IFKW
population was conducted per the specific requirements and standards of
the ESA regarding whether to conduct formal, rather than informal,
consultation under ESA section 7. This finding under the authority of
the ESA does not foreclose the issuance of a NID under MMPA; rather, it
means that some level of take is anticipated requiring formal
consultation under the ESA.
Comment 12: CRC, HSUS, and Earthjustice commented that the results
presented by McCracken (2014) indicate that M&SI in the longline
fisheries likely exceed PBR. They argue that effort is likely to be
closer to 1,000,000 hooks set in the ``open area'' than to the 600,000
hooks analyzed in the model, because effort will shift from the area
that was previously (pre-FKWTRP) open seasonally to the area just
outside the now-closed (post-FKWTRP) area. They claim the effort will
not be redistributed evenly, as is analyzed in the model, but that it
will cluster closer to shore and within the MHI IFKW stock range,
creating pockets of higher effort which the model does not capture.
Response: NMFS completed a predictive model that, among other
things, evenly redistributed an equal number of hooks that were removed
from the area now closed to longlining under the FKWTRP to offshore
areas in the action area that remain open to longlining. NMFS does not
anticipate that this redistributed effort will be close to or over
1,000,000 hooks in the ``open area'' or that redistributed effort will
cluster along the boundaries of the expanded closure due to the nature
of the fishery and the actual effort that was observed in 2013.
Longline gear is typically set across 30-40 miles of water, and while
some vessels will likely fish in the open area along the edge of the
expanded longline closure, redistributed effort is most likely to occur
where pelagic fishery resources are being caught at any given time.
Since NMFS cannot predict where the fish will be found at any given
time, we believe it was appropriate to assume an even redistribution of
that effort throughout the action area.
In addition, logbook effort data were plotted to determine if there
were clusters of effort just outside the boundary of the closed area,
as indicated by the commenters. This an important consideration because
false killer whale bycatch within the MHI insular/pelagic stock overlap
zone is prorated to stock based on distance from shore, so interactions
closer to shore have a higher probability of being assigned to the
insular stock. The logbook data show that in 2013, proportionally less
effort was concentrated on the inner boundary of the open area in 2013
than in previous years (McCracken, pers. comm.), indicating that the
clustering effect suggested by the commenters is not occurring.
In 2008, just over a million hooks were set in the ``open area''
but effort has remained well below since that time (see Table 1 in
McCracken 2014). In 2013 (the first year after the implementation of
the FKWTRP), logbook data indicate that there were 98 sets and 344,808
hooks set in the open area, below the 600,000 hooks that were analyzed
in the model (McCracken, pers. comm.). NMFS believes that effort may
vary in the open area but will not likely reach levels of 1,000,000
hooks based on the last several years of data and current regulatory
measures in place for false killer whales under the FKWTRP. However,
NMFS will continue to monitor fishing effort to identify any changes in
the operation of the fishery that may warrant adjustments to its models
and the effects on the NID analysis.
Comment 13: Earthjustice and HSUS argued that it is premature to
rely on the FKWTRP to ensure that the deep-set fishery has a negligible
impact to MHI IFKWs because it has not yet been shown to be effective.
The commenters cite false killer whale takes that have been observed
since the FKWTRP went into effect, including one for which the required
gear did not perform as expected to straighten and release the hooked
animal. One commenter expressed concern that NMFS is relying on a
sample size of only one event to show that the new gear can straighten
effectively and release a hooked animal.
Response: NMFS notes that, although the Plan has been in place for
less than two years, its required measures represent the consensus
effort of a diverse team of conservationists, scientists, and federal
and state officials, to put in place conservation and management
measures they believe will be effective in meaningfully reducing
impacts on MHI IFKW. The FKWTRP has been in effect since December 31,
2012, and its gear regulations for the deep-set fishery in effect since
February 27, 2013. Through the FKWTRP, NMFS has a tool with which to
monitor and respond to impacts to MHI IFKW if M&SI should exceed PBR.
The FKWTRP and the FKWTRT process provide an important adaptive
management framework with which to identify, through reporting and
monitoring, unanticipated impacts to the stock, and to develop
additional remedial
[[Page 62116]]
measures, such as through amendment of the FKWTRP, or through emergency
rulemaking, to ensure any future impacts do not result in significant
adverse impacts.
The FKWTRP is expected to reduce interactions with MHI IFKWs,
primarily as a result of the revision to the existing longline
prohibited area surrounding the MHI. The Team's recommended revision
implemented by NMFS eliminated the seasonal change in the boundary on
the windward side of the MHI, thereby prohibiting longlining year-round
within a large majority of the MHI IFWK's stock range. Since the FKWTRP
and the revised longline prohibited area went into effect, there have
been no observed false killer whale interactions within the range of
the insular stock. The observed interactions noted by the commenters
that occurred since the FKWTRP went into effect involved pelagic false
killer whales and were not within the range of the insular stock.
In addition, the FKWTRP includes gear modifications that are
expected to reduce the number and severity of false killer whale
hookings. This expectation is supported by NMFS's analysis (e.g.,
bootstrap simulations detailed in Forney et al. 2011) and an experiment
that demonstrated that the required hooks are capable of straightening
and releasing a hooked false killer whale (Bigelow et al. 2012). There
are now three observations of false killer whales straightening hooks
that meet the FKWTRP's requirements and releasing the whales with no
gear attached. NMFS, in consultation with the Team, will continue to
monitor the effectiveness of the FKWTRP's gear and other requirements.
While NMFS cannot yet fully evaluate the impact of the Plan on
false killer whale M&SI, since the implementation of the Plan there
have been no observed false killer whale or blackfish interactions in
the range of the MHI IFKW, and where interactions have occurred, the
gear performed in a manner that the Plan intended, which means the hook
straightened and the animal was released from the gear.
Comment 14: The HSUS, CRC, the Commission, and Earthjustice state
that Criterion 3 is not met because the population trend is not stable
or increasing and they point to the SARs, the 2010 status review, and
Silva et al. (2013), as evidence that the population is declining.
Response: Although MHI IFKW are believed to have declined markedly
during the 1990s, at this time, their current population trajectory is
unknown (Oleson et al. 2010). Nevertheless, NMFS acknowledges the need
for more reliable information regarding stock trajectory, but notes
that this uncertainty, along with the presence of substantial observer
coverage in this fishery, was considered in the Team's deliberations
and in the adoption of the specific measures for minimizing the impact
of the fishery on IFKWs. As such, NMFS believes that the measures in
place, coupled with the FKWTRT process, provide a meaningful, adaptive
management tool with which to quickly monitor, identify, and respond to
any unanticipated longline fishery impacts to the MHI IFKW population.
NMFS will continue to conduct and support research on the MHI IFKW
population and trends.
Comment 15: CRC and the Commission recommended that NMFS work with
State of Hawaii to collect data on and monitor marine mammal
interactions in non-longline fisheries (e.g., via an observer program).
Response: NMFS recognizes the need for additional collection of
information on marine mammal interactions in non-longline fisheries
around Hawaii and that the State currently has minimal reporting
requirements for marine mammal interactions with state-managed
fisheries. NMFS continues to consult with the State of Hawaii and other
partners to assess and address marine mammal interactions in state-
managed fisheries. Data collection in state fisheries has been
identified as a research priority by the FKWTRT. NMFS and the State of
Hawaii have updated their existing ESA Section 6 Cooperative Agreement
to include support for research and bycatch reduction for the Hawaiian
insular false killer whale. Additionally, as indicted in the response
to Comment 7, the State of Hawaii intends to submit a proposal for
federal funding in response to the recent ESA Section 6 Federal Funding
Opportunity that intends to address priority recovery actions for the
MHI IFKW. NMFS will continue to work with the Hawaii Department of Land
and Natural Resources within available budget and resource constraints
to improve data collection in these fisheries.
Comment 16: The HSUS stated that there is no recovery plan in place
for the MHI IFKW stock, and that without a recovery plan to address the
all anthropogenic impacts, permitting take in the deep-set fishery
would violate the precautionary principle. The HSUS also stated that no
take should be authorized in the absence of a recovery plan for this
stock.
Response: Section 101(a)(5)(E) allows for the incidental taking of
depleted marine mammal stocks by commercial fisheries, subject to
certain findings and requirements. One such finding is that ``a
recovery plan has been developed or is being developed for such species
or stock pursuant to the Endangered Species Act of 1973'' (16 U.S.C.
1371(a)(5)(E)(i)(II)). NMFS acknowledges that a recovery plan has not
yet been finalized, but the process to develop a recovery plan has been
initiated (78 FR 60850, October 2, 2013).
Comment 17: The HSUS noted that making a NID triggers the
requirement to reinitiate consultation and to issue an incidental take
statement (ITS) under the ESA. They state that the 2012 Biological
Opinion for the shallow-set longline fishery will need to be
reinitiated due to the negligible impact determination. They state that
the Biological Opinion being prepared for the deep-set fishery will
require an ITS for the take of listed species and that the ITS must
specify reasonable and prudent measures to mitigate the impact of take
on the species and the individual animals to be taken, as well as a
trigger for reiniation of consultation. The HSUS argues that reliance
on the FKWTRP is risk-prone, given the on-going false killer whale
interactions, so additional mitigation measures must be adopted. They
also state that a single take would/should trigger emergency suspension
of the fishery, as it would exceed the PBR for the three-year
authorization.
Response: Because the MMPA 101(a)(5)(E) permit process analyzes
impacts of the fishery as it is currently managed under existing
fishery management plan regulations, reinitiation of consultation is
only required if one or more of the triggers in 50 CFR 402.16 are met.
Because NMFS has determined that there has been no take of MHI IFKW or
sperm whales by the shallow-set fishery, the permit does not cover the
shallow set fishery for those stocks. Moreover, issuance of the permit
will not result in impacts to CNP humpback whales that were not already
analyzed in the 2012 biological opinion; accordingly, reinitiation of
consultation is not required.
With respect to the deep-set fishery, NMFS completed a Biological
Opinion on September 19, 2014, consistent with ESA section 7, which
considered information in the NID analysis. An ITS specifies reasonable
and prudent measures and terms and conditions for mitigating the impact
of take of protected species, as well as specify terms for reinitiation
of consultation, and will become valid for cetaceans once this permit
is finalized. This MMPA permit, although related to the
[[Page 62117]]
Biological Opinion, is a separate determination that considers those
factors specified in MMPA section 101(a)(5)(E).
NMFS disagrees that it is premature to rely on the FKWTRP to ensure
that M&SI is less than PBR in the deep-set fishery which is described
in greater detail in comment 13. We also disagree that a single take in
the overlap zone should trigger an emergency suspension of the fishery
because such take would exceed PBR. Based on the best available
science, after an expansion factor (5) is applied to account for
observer coverage (20%) and a proration factor (15%) is applied to
account for the probability that an interaction in the overlap zone
involves a MHI IFKW, a single take in the overlap area would be the
equivalent of 0.75 MHI IFKW. As a term and condition of the September
19, 2014 Biological Opinion on the deep-set fishery (NMFS 2014), two
M&SI in the overlap area during any three-year period would trigger
reinitiation of consultation and require the immediate convening of the
FKWTRT to provide recommendations regarding possible emergency
measures.
Comment 18: Earthjustice stated that NMFS should close off the
entire 140 km range to eliminate the risk of longline fishery
interactions with the MHI IFKW.
Response: This action is limited to determining whether to issue a
permit under MMPA section 101(a)(5)(E), which would allow the Hawaii-
based longline fisheries, as currently managed and operated, to
incidentally take individuals from certain ESA-listed marine mammal
stocks. Potential future measures to expand the range of the MHI
longline fishing prohibited area, either through emergency rulemaking
or amendment of the FKWTRP, are beyond the scope of this decision.
With regard to the commenter's suggestion of excluding longline
fishing form the entire known range of the stock, the FKWTRP
regulations prohibit longline fishing within the entire core range and
a large portion of the ``extended'' range of the MHI IFKW stock (which
extends out to 140 km from shore), which NMFS determined would
substantially reduce the risk of MHI IFKW interactions in the longline
fisheries. The FKWTRT unanimously concluded that by permanently
extending the seasonal boundary of the MHI longline prohibited area to
include all overlap areas where prorated interactions with MHI IFKW and
pelagic false killer whales have occurred, the risk to MHI IFKW would
be significantly reduced. NMFS emphasizes that like all small
cetaceans, MHI IFKW do not confine their movements to precise areas.
Nevertheless, while we cannot eliminate all risk to the MHI IFKW from
longline fishing, predictive modeling based on precautionary
assumptions projects no more than one M&SI every four years. Under
these circumstances, NMFS does not believe a further increase in the
longline closure area is necessary to protect MHI IFKWs. However, if
the FKWTRP is not effective in protecting the stock, (i.e., if M&SI
should exceed PBR), then NMFS, in consultation with the FKWTRT, will
develop and implement additional measures to meet the MMPA take
reduction goals and will re-evaluate the NID.
Comment 19: CRC states that given the small PBR for MHI IFKW and
the relatively small overlap between the fishery and the population's
range, there is insufficient observer coverage within the ``open area''
to produce reliable estimates of longline M&SI for the MHI IFKW and
that an analysis to determine the sample size of observer coverage is
required within the area to have a reasonable probability of detecting
bycatch that may approach or exceed PBR.
Response: NMFS acknowledges CRC's concern regarding the adequacy of
observer coverage levels to detect take levels that could exceed PBR,
given the stock's small PBR level and the small area of overlap between
the fisheries and the stock. NMFS's Hawaii Longline Observer Program is
designed to provide representative coverage of fishing effort by the
fleet, but is not designed to cover specific areas of operation.
However, in considering CRC's comment, we evaluated the level of
observer coverage in the ``open area'' (the area of overlap between the
longline fisheries and MHI IFKWs). We calculated this as the number of
trips observed within the area divided by the number of trips recorded
as fishing within the area. We note that these coverage levels do not
imply a random sample, a representative sample, or that coverage was
constant throughout the year. Despite these caveats, in recent years,
coverage in the open area has been as follows: 2008, 13.6%; 2009,
16.1%; 2010, 25.4%; 2011, 18.8%; 2012, 26.1%; 2013, 22.4%, which is
20.4% for a six-year average. An analysis described in the report from
NMFS's 2011 workshop on revising the GAMMS (Moore and Merrick, 2011)
indicates that for a stock with a PBR of 1.0 and observer coverage of
20%, data pooled across four or more years would achieve an
approximately unbiased estimate of M&SI. NMFS regularly pools M&SI
estimates across five years to produce average annual estimate for
comparison to PBR and believes that this level of observer coverage in
the open area, combined with the pooling of M&SI data provide
sufficiently reliable information with which to assess IFKW bycatch in
the deep-set longline fishery.
