Endangered and Threatened Wildlife and Plants: Final Rule To List 
the Maui Dolphin as Endangered and the South Island Hector's Dolphin as 
Threatened Under the Endangered Species Act

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We, NMFS, issue a final rule to list the Maui dolphin 
(Cephalorhynchus hectori maui) as endangered and the South Island (SI) 
Hector's dolphin (C. hectori hectori) as threatened under the 
Endangered Species Act (ESA). We considered comments submitted on the 
proposed listing rule and have determined that the Maui dolphin and the 
SI Hector's dolphin warrant listing as endangered and threatened 
species, respectively. We will not designate critical habitat for 
either of these dolphin subspecies, because the geographical areas 
occupied by these dolphins are entirely outside U.S. jurisdiction, and 
we have not identified any unoccupied areas within U.S. jurisdiction 
that are currently essential to the conservation of either of these 
subspecies.

DATES: This final rule is effective October 19, 2017.

ADDRESSES: Endangered Species Division, NMFS Office of Protected 
Resources (F/PR3), 1315 East West Highway, Silver Spring, MD 20910.

SUPPLEMENTARY INFORMATION:

Background

    On July 15, 2013, we received a petition from WildEarth Guardians 
to list 81 marine species or populations as endangered or threatened 
species under the ESA. We determined that the petition had sufficient 
merit for further consideration, and status reviews were initiated for 
27 of the 81 species or populations, including the Hector's dolphin 
(Cephalorhynchus hectori; 78 FR 63941, October 25, 2013; 78 FR 66675, 
November 6, 2013; 78 FR 69376, November 19, 2013; 79 FR 9880, February 
21, 2014; and 79 FR 10104, February 24, 2014). On September 19, 2016, 
we published a proposed rule to list the Maui dolphin (Cephalorhynchus 
hectori maui) as endangered and the SI Hector's dolphin (C. hectori 
hectori) as threatened (81 FR 64110). We requested

[[Page 43702]]

public comments on the information in the proposed rule and the 
associated status review during a 60-day public comment period, which 
closed on November 18, 2016. This final rule provides a discussion of 
the public comments received in response to the proposed rule and our 
final determinations on the petition to list the Maui dolphin and the 
SI Hector's dolphin under the ESA. The findings and relevant Federal 
Register notices for the other species and populations addressed in the 
petition can be found on our Web site at www.nmfs.noaa.gov/pr/species/petition81.htm.

Listing Determinations Under the ESA

    We are responsible for determining whether species meet the 
definition of threatened or endangered under the ESA (16 U.S.C. 1531 et 
seq.). To make this determination, we first consider whether a group of 
organisms constitutes a ``species'' under the ESA, then whether the 
status of the species qualifies it for listing as either threatened or 
endangered. Section 3 of the ESA defines a ``species'' to include any 
subspecies of fish or wildlife or plants, and any distinct population 
segment of any species of vertebrate fish or wildlife which interbreeds 
when mature. The Maui dolphin, C. hectori maui, and the SI Hector's 
dolphin, C. hectori hectori, are formally recognized subspecies (Baker 
et al., 2002, Pichler 2002) and thus meet the ESA definition of a 
``species.''
    Section 3 of the ESA defines an endangered species as ``any species 
which is in danger of extinction throughout all or a significant 
portion of its range'' and a threatened species as one ``which is 
likely to become an endangered species within the foreseeable future 
throughout all or a significant portion of its range.'' We interpret an 
``endangered species'' to be one that is presently in danger of 
extinction. A ``threatened species,'' on the other hand, is not 
presently in danger of extinction, but is likely to become so in the 
foreseeable future (that is, at a later time). In other words, the 
primary statutory difference between a threatened species and 
endangered species is the timing of when a species may be in danger of 
extinction, either presently (endangered) or in the foreseeable future 
(threatened).
    When we consider whether a species might qualify as threatened 
under the ESA, we must consider the meaning of the term ``foreseeable 
future.'' It is appropriate to interpret ``foreseeable future'' as the 
horizon over which predictions about the conservation status of the 
species can be reasonably relied upon. The foreseeable future considers 
the life history of the species, habitat characteristics, availability 
of data, particular threats, ability to predict threats, and the 
reliability to forecast the effects of these threats and future events 
on the status of the species under consideration. Because a species may 
be susceptible to a variety of threats for which different data are 
available regarding the species' response to that threat, or which 
operate across different time scales, the foreseeable future is not 
necessarily reducible to a particular number of years.
    Section 4(a)(1) of the ESA requires us to determine whether any 
species is endangered or threatened due to any one or a combination of 
the following five threat factors: The present or threatened 
destruction, modification, or curtailment of its habitat or range; 
overutilization for commercial, recreational, scientific, or 
educational purposes; disease or predation; the inadequacy of existing 
regulatory mechanisms; or other natural or manmade factors affecting 
its continued existence. We are also required to make listing 
determinations based solely on the best scientific and commercial data 
available, after conducting a review of the species' status and after 
taking into account efforts being made by any state or foreign nation 
to protect the species.
    In assessing the extinction risk of these two subspecies, we 
considered demographic risk factors, such as those developed by 
McElhany et al. (2000), to organize and evaluate the forms of risks. 
The approach of considering demographic risk factors to help frame the 
consideration of extinction risk has been used in many of our previous 
status reviews (see http://www.nmfs.noaa.gov/pr/species for links to 
these reviews). In this approach, the collective condition of 
individual populations is considered at the species level (or in this 
case, the subspecies level) according to four demographic viability 
factors: abundance and trends, population growth rate or productivity, 
spatial structure and connectivity, and genetic diversity. These 
viability factors reflect concepts that are well-founded in 
conservation biology and that individually and collectively provide 
strong indicators of extinction risk.
    Scientific conclusions about the overall risk of extinction faced 
by the Maui dolphin and the SI Hector's dolphin under present 
conditions and in the foreseeable future are based on our evaluation of 
the subspecies' demographic risks and section 4(a)(1) threat factors. 
Our assessment of overall extinction risk considered the likelihood and 
contribution of each particular factor, synergies among contributing 
factors, and the cumulative impact of all demographic risks and threats 
on each subspecies.
    Section 4(b)(1)(A) of the ESA requires the Secretary, when making a 
listing determination for a species, to take into consideration those 
efforts, if any, being made by any State or foreign nation, or any 
political subdivision of a State or foreign nation, to protect the 
species. Therefore, prior to making a listing determination, we also 
assess such protective efforts to determine if they are adequate to 
mitigate the existing threats.

Summary of Comments

    In response to our request for comments on the proposed rule, we 
received 75 comments. The comments were submitted by multiple 
organizations and individual members of the public from a minimum of 
seven countries (Australia, Bahamas, Canada, England, Ireland, New 
Zealand, and the United States). All of the comments were supportive of 
the proposed endangered listing for the Maui dolphin. Several 
commenters suggested listing the SI Hector's dolphin as endangered, and 
one comment was opposed to the proposed threatened listing for the SI 
Hector's dolphin. Summaries of comments received regarding the proposed 
rule and our responses are provided below.
    Comment 1: A large majority of the comments were general statements 
expressing support for listing Maui dolphins as endangered and SI 
Hector's dolphins as threatened under the ESA. Most of these comments 
were not accompanied by information or references. Some of the comments 
were accompanied by information that is consistent with, or cited 
directly from, our proposed rule or draft status review report. Several 
of the comments included pointed statements regarding the inadequacy of 
current management efforts to reduce bycatch of Hector's dolphins. 
Several other comments were associated with a ``Let's Face It'' 
campaign to protect Maui dolphins, and in one case, a commenter 
provided a link to an online, visual petition from ``Let's Face it'' 
consisting of photos of the over 9,400 people who participated in the 
campaign. The Marine Mammal Commission in particular concurred with our 
proposed endangered listing of Maui dolphins, and recommended we 
proceed with a final rule listing them as such under the ESA.
    Response: We acknowledge all of these comments and the considerable 
public interest expressed in support of

[[Page 43703]]

the conservation of the SI Hector's and Maui dolphins.
    Comment 2: Two scientists from the University of Otago, New 
Zealand, submitted an unpublished report (referred to here as Slooten 
and Dawson 2016) presenting population viability analyses (PVAs), 
estimates of Potential Biological Removal (PBR), and projected 
population trends for Maui and SI Hector's dolphins. The report updates 
previously published analyses (e.g., Slooten 2007a; Slooten and Dawson 
2010) by incorporating the recent abundance estimates reported by Baker 
et al. (2016) for Maui dolphins and by Mackenzie and Clement (2014, 
2016) for SI Hector's dolphins. These updated analyses were conducted 
to explore how the new abundance estimates affect previous conclusions 
about risk and population viability. The report also reviews the 
available data on fishery-observer coverage and available bycatch data 
by location, year, and gear type (gillnet, trawl, or craypot). The 
report discusses several limitations of the available bycatch data and 
asserts the data provide an under-estimate of the actual level of 
bycatch mortality.
    The commenters' updated PBR (using a recovery factor of 0.1) for 
Maui dolphins ranges from 0.05 to 0.12, depending on the assumed per 
capita growth rate (Rmax). Their estimated rate of population decline 
is 2 percent per year, with a 95 percent confidence interval (CI) that 
ranges from a 1.6 percent decline to a 4.8 percent increase per year, 
which the commenters note indicates a high level of uncertainty 
regarding the population trend. The commenters present a Bayesian 
linear regression analysis that indicates there is a 68 percent 
probability that the Maui dolphin population is continuing to decline, 
and their power analysis indicates that the ability (statistical power) 
to detect population trends in continued population surveys for Maui 
dolphins is very low.
    The updated PBR estimate provided by the commenters for the SI 
Hector's dolphin ranges from 3 to 24 dolphins per year, depending on 
the value of Rmax and the offshore range of the dolphins applied. 
Results of the updated PVA suggest that the abundance of SI Hector's 
dolphins has declined by 70 percent over the last three generations (39 
years), and that the subspecies will continue to decline to 8,283 
dolphins (95 percent CI: 4,925-13,931) by the year 2050. The commenters 
conclude that the new, higher abundance estimate for the SI Hector's 
dolphins is more than offset by the increased degree of overlap between 
fishing activities and the more extensive offshore distribution of 
dolphins on the east coast of the South Island.
    Response: We thoroughly reviewed and considered the analyses and 
information presented in this report.
    In response to the information provided in this comment, we updated 
our status review report (Manning and Grantz 2017) to include the 
recent abundance estimate for Maui dolphins from Baker et al. (2016), 
who reported an abundance estimate of 63 dolphins 1 year of age and 
older (95 percent CI: 57-75). This new abundance estimate is based on a 
long-term genetic mark-recapture study and is within the 95 percent CI 
of the previous estimate resulting from this work (i.e., 55 dolphins 1 
year of age and older (95 percent CI: 48-69), Hamner et al., 2014b). 
Estimates of the rate of population decline provided by the commenters 
are consistent with those provided recently by Baker et al. (2016): 
Both sources indicate an annual rate of decline of about 2 percent with 
a high degree of uncertainty. The updated PBR estimates reported by the 
commenters (i.e., 0.05 (or one dolphin every 20 years) to 0.12 (or one 
dolphin every 8.3 years)) are also similar to those reported previously 
using older abundance estimates--e.g., 0.16 (Slooten et al., 2006a), 
0.044-0.10 (Wade et al., 2012).
    Overall, while the commenters' report does provide updated 
analyses, the results presented and the more recent population 
abundance estimate for Maui dolphins do not change the outlook for this 
subspecies. The subspecies is at a critically low abundance, is still 
considered to have a very low threshold for human-caused mortality 
(i.e., PBR is still well below 1.0), and is likely to undergo continued 
decline. Therefore, we find that the new abundance estimate and revised 
analyses support, and do not alter, our previous conclusion that the 
Maui dolphin meets the definition of endangered under the ESA.
    As explained by the commenters, previous estimates of PBR and 
population viability analyses for the SI Hector's dolphins relied on 
earlier, lower abundance estimates; whereas, the analyses prepared by 
the commenters use the latest abundance estimate of 14,849 SI Hector's 
dolphins (95% CI = 11,923-18,492, Mackenzie and Clement 2014, 2016). As 
discussed in more detail in the status review report (Manning and Gantz 
2017), this most recent abundance estimate for the SI Hector's dolphin 
is based on a series of aerial, line-transect surveys that were 
conducted around the South Island during 2010-2015 (Clement et al., 
2011, Mackenzie and Clement 2014, Mackenzie and Clement 2016). These 
surveys extended farther offshore than the previous island surveys (up 
to 20 nautical miles offshore versus 4 to 10 nautical miles), a factor 
that, to some extent, contributed to the larger abundance estimate 
relative to the previous estimate. Interestingly, despite the much 
larger population abundance estimate for this subspecies, the results 
of the updated analyses for the SI Hector's dolphin provided by the 
commenters do not suggest a substantially different outlook for the 
subspecies.
    The commenters provide updated PBR estimates for SI Hector's 
dolphins by region. Unfortunately, however, the east coast of the South 
Island is the only region for which bycatch estimates are available 
following implementation of management measures in 2008, making 
comparisons of bycatch levels to PBR estimates for other regions 
difficult. The updated PBR estimates for the east coast population 
presented by the commenters (3-15 dolphins per year) are higher than 
those published previously by the commenters (0.57-1.28, Slooten and 
Dawson 2008b); however, they are still largely below the level of 
bycatch estimated for the east coast using commercial gillnetting 
observer data (23 dolphins, min-max range of 4--48, Slooten and Davies 
2012). This information suggests that bycatch in commercial gillnets 
alone may be occurring at an unsustainable rate in this region.
    The results of the updated PVAs provided by the commenters for the 
SI Hector's dolphins suggest that a large historical decline in 
abundance occurred since the 1970's, similar to the finding of previous 
analyses (e.g., Slooten 2007a, Slooten and Dawson 2010). The updated 
PVA also predicts continued decline by about 44 percent by the year 
2050 given current fishing effort, estimated bycatch, and current 
management measures. It is not clear, however, what bycatch estimates 
were applied in this analysis; and, as noted by the commenters, there 
is considerable uncertainty regarding the level of bycatch across the 
range of the subspecies. This and previous analyses have relied on very 
limited bycatch estimates, which are only available for a small number 
of regions and years and only for commercial gillnet fisheries. These 
shortcomings have been noted previously and cannot be remedied until 
sufficient, reliable bycatch data become available.
    Overall, the results of the analyses presented by the commenters 
are consistent with our previous conclusions that the SI Hector's 
dolphin

[[Page 43704]]

has experienced large historical declines in abundance, is likely 
experiencing unsustainable levels of bycatch, and is likely to continue 
to decline under existing management protections. Therefore, we 
conclude the information provided in the commenters' report does not 
alter our finding that the SI Hector's dolphin meets the definition of 
threatened under the ESA.
    Comment 3: Five commenters requested that we list the SI Hector's 
dolphin as endangered under the ESA. One of these commenters also urged 
that we enact strict protections immediately for SI Hector's dolphins 
(and Maui dolphins). One of the commenters stated that an endangered 
listing for SI Hector's dolphins was justified because this subspecies 
consists of a network of unique, local populations or ``Distinct 
Population Segments'' that are small, declining, and increasingly 
fragmented. Three papers on specific subpopulations of SI Hector's 
dolphins (i.e., Rayment et al., 2009a, Turek et al., 2013, Weir and 
Sagnol 2015) and one study on genetic differentiation among populations 
(i.e., Hamner et al., 2012a) were provided to demonstrate fragmentation 
of populations. This commenter also stated that bycatch levels remain 
high because current fisheries management measures cover only a small 
portion of the SI Hector's dolphin's habitat and are poorly monitored 
and enforced. A report reviewing marine fisheries catch data in New 
Zealand (i.e., Simmons et al., 2016) and a link to video footage 
showing the capture of two SI Hector's dolphins were provided to 
support this statement.
    Response: In response to these comments, we reviewed the 
information and references provided and considered whether the 
available information indicates the SI Hector's dolphin meets the 
definition of endangered under the ESA.
    We agree that SI Hector's dolphin comprises multiple populations, 
some of which have been estimated to be very small, and that the 
population structure, in combination with other factors such as small 
home ranges (e.g., Rayment et al., 2009a), is contributing to the 
extinction risk for this subspecies. The best available data indicate 
that the SI Hector's subspecies comprises three, regional populations 
that can be distinguished geographically and genetically--an east coast 
(ECSI), west coast (WCSI), and south coast population (SCSI; Pichler 
2002, Hamner et al., 2012). Additional population structuring within 
these larger geographic regions has also been indicated in genetic 
studies (e.g., Te W[aelig]w[aelig] Bay and Toetoe Bay within the SCSI, 
Hamner et al., 2012a). Two references cited by the commenter present 
analyses of photo-identification data that provide additional evidence 
of small, localized or fragmented populations off Otago and Kairkoura 
on the ECSI (Turek et al., 2013, Weir and Sagnol 2015). Because we had 
not cited these latter two references previously, we have expanded our 
discussion of population structure in the status review report (Manning 
and Grantz 2017) to incorporate information from these two studies.
    The references provided, however, do not alter our interpretation 
of the available data regarding population structure and its 
contribution to extinction risk for SI Hector's dolphins. As discussed 
in the status review report and proposed rule, the available genetic 
evidence (based on both mitochondrial DNA and microsatellites) 
indicates that there are low levels of migration between most 
neighboring local populations over distances shorter than 100 km 
(Hamner et al., 2012a). While strong genetic differentiation has been 
detected among the regional populations, very few intra-regional 
comparisons of populations in the ECSI and WCSI regions have been 
significant (Pichler 2002; Hamner et al., 2012a). Analysis of levels of 
genetic differentiation among sample locations within regions suggests 
there is sufficient gene flow to maintain genetic diversity within the 
ECSI and WCSI regions; however, the very restricted gene flow detected 
between local populations in the SCSI region (i.e., beween Te WaeWae 
and Toetoe Bays) does pose a conservation concern (Hamner et al., 
2012a). Connectivity between the small, local populations within each 
region is very important to the overall status of this subspecies, and 
additional loss of connectivity would increase risks of genetic drift, 
loss of genetic diversity, and extinction. Thus, as we concluded in our 
status review (Manning and Grantz 2017), the spatial structure and 
connectivity among SI Hector's populations is posing a moderate risk to 
the subspecies, but this factor, either alone or in combination with 
other threats, does not put the subspecies at immediate risk of 
extinction (Manning and Grantz 2017). Information provided by the 
commenter does not provide new or different information regarding the 
degree of population fragmentation, abundance, or the rate of decline 
of any populations. Therefore, we find that the information provided by 
the commenter is consistent with the analysis presented in our status 
review and does not alter our conclusion that the SI Hector's dolphin 
meets the definition of threatened under the ESA.
    We also agree with the comment that bycatch of SI Hector's dolphins 
continues to pose a threat despite existing fisheries management 
efforts. As we discuss in our status review, the risk of bycatch in 
commercial and recreational trawl and gillnet fisheries remains high 
given the known distribution of the dolphins relative to areas open to 
fishing, especially on the west and north coasts of the South Island 
(Faustino et al., 2013, Slooten 2013). The report provided by the 
commenter, which reviewed New Zealand marine fisheries catch data from 
1950-2010 (i.e., Simmons et al., 2016), indicates a serious degree of 
under-reporting of catch and discards in commercial fisheries; however, 
the report documents the under-reporting of only a single Hector's 
dolphin by one fishing vessel. Video footage provided by one of the 
commenters was recorded as part of an investigation, called Operation 
Achilles, conducted by the New Zealand Ministry for Primary Industries' 
(MPI) following earlier video evidence of dolphin bycatch obtained 
during a pilot electronic monitoring program. The footage provided by 
the commenter was made publicly available by MPI and shows the capture 
of two SI Hector's dolphins; and according to the associated reports 
provided by MPI (http://mpi.govt.nz/protection-and-response/environment-and-natural-resources/sustainable-fisheries/independent-review-of-prosecution-decisions/), only one of the two dolphins was 
reported as legally required. Overall, while the report and the video 
provide definitive evidence that under-reporting of bycatch of Hector's 
dolphins has occurred, this information alone does not augment the 
available bycatch data or improve our understanding of the extent or 
rate of bycatch such that an endangered listing for the SI Hector's 
dolphin is warranted.
    Lastly, we note that one of the commenters who requested an 
endangered listing for the SI Hector's dolphin equated the population 
structure of SI Hector's dolphins with ``distinct population segments'' 
(DPSs), which are included in the ESA definition of a ``species'' and 
are units of vertebrate populations that can be listed under the ESA. 
We address DPSs and the issue of whether populations of SI Hector's 
dolphins should be identified as DPSs under our response to Comment 4 
(below).
    Comment 4: The Marine Mammal Commission commented that the 
information provided in our status

[[Page 43705]]

review and proposed rule is insufficient to support a threatened 
listing for the SI Hector's dolphin. The comment discussed four main 
lines of reasoning in support of that statement: (1) In contrast to the 
Maui dolphin, the SI Hector's dolphins remain fairly abundant; (2) the 
length of the ``foreseeable future'' we applied is unrealistically 
long; (3) bycatch is currently being mitigated through management 
actions, and we cannot assume that additional management measures will 
not be implemented by New Zealand; and, (4) while disease and tourism 
are potential threats, their population-level impacts are uncertain. 
The Commission recommended that we revise the length of the 
``foreseeable future'' used in the analysis, reconsider whether 
existing regulatory mechanisms are inadequate to address the threat of 
bycatch, and reconsider our proposal to list the SI Hector's dolphin 
subspecies as threatened.
    The Commission also noted that one or more of the regional 
populations of SI Hector's dolphins could meet the definition of a DPS. 
The Commission states that the status review and proposed rule did not 
explore the possibility that any of these populations could merit 
separate listing consideration or could contribute to a threatened 
listing of the subspecies.
    Response: We agree with the Commission that the current abundance 
estimate for the SI Hector's dolphin is fairly high relative to the 
estimated population abundance of Maui dolphins, which is at a 
critically low level. The estimated abundance of the entire SI 
subspecies was an important consideration in our risk analysis and 
contributed to our finding that the SI Hector's dolphin is not 
presently in danger of extinction and thus does not meet the definition 
of endangered under the ESA. However, we did not rely on estimates of 
abundance as an exclusive determinant of this subspecies' risk of 
extinction. Rather, and as is our standard practice when conducting 
status reviews under the ESA and as articulated in our status review, 
our analysis also considered other demographic risk factors, including 
population growth/productivity, spatial structure and connectivity, and 
genetic diversity. As required under the ESA, we also considered 
threats and protective efforts. Thus, for SI Hector's dolphins in 
particular, we considered the estimates of large historical declines in 
abundance, the observed loss of genetic diversity, the limited 
connectivity of populations, as well as ongoing threats such as bycatch 
and the projections of continued declines despite management efforts. 
Ultimately, all of this information was used in reaching the conclusion 
that this subspecies faces a level of risk that warrants listing it as 
threatened under the ESA.
    We disagree with the comment that we applied an ``unrealistically 
long'' timeframe as the ``foreseeable future'' in our analysis and that 
we should revise it to be ``a period of time relevant to mitigation of 
the bycatch threat.'' The comment explicitly refers to a discussion 
presented in both the status review and proposed rule regarding the 
rate of decline of SI Hector's dolphins around Banks Peninsula as 
estimated by Gormley et al. (2012) and our extrapolation of that rate 
of decline to the entire subspecies. The result of our calculation was 
a 50 percent decline in the population in about 138 years and an 80 
percent decline in about 321 years. We did not, however, apply these 
timeframes as the ``foreseeable future'' as asserted by the Commission. 
As we stated in the proposed rule (81 FR 64121, September 19, 2016), 
these are simply calculations based on the limited data available, and 
we did not use them to establish any specific thresholds for 
determining when the subspecies may be in danger of extinction. The 
status review also characterizes this calculation as ``grossly over-
simplified and not realistic'' and explains that a trend analysis and a 
projection of the time to extinction is not currently possible (Manning 
and Grantz 2017). We also stated in both the status review and proposed 
rule that the actual rate of decline of the subspecies remains unclear 
given the deficiency of bycatch mortality data. We note that we are not 
required to develop a specific rate of decline in order to find that a 
species meets the definition of threatened under the ESA. In this 
particular case, the available data do not support such a calculation. 
Lastly, we note that our ultimate determination regarding the status of 
the SI Hector's dolphin does not exclusively depend on the threat of 
bycatch or the rate of decline attributable to bycatch alone. Our 
status review and proposed rule discuss available data on other 
demographic risk factors and threats, and our conclusion that the SI 
Hector's dolphin warrants listing as threatened was based on 
consideration of these multiple threats, each of which may be operating 
at different time scales. We made minor edits to the status review 
report to clarify this issue.
    As requested by the Commission, we reconsidered our conclusion 
regarding the adequacy of existing management measures relative to the 
threat of bycatch of SI Hector's dolphins. We also searched for 
additional data and information regarding bycatch of Hector's dolphins 
and associated management measures. We did not find any updated 
information regarding the rate or extent of bycatch or the 
effectiveness of current bycatch reduction efforts around the South 
Island, nor did the Commission provide any data or information 
regarding the adequacy of bycatch management measures. We did, however, 
receive a letter, dated November 22, 2016, from the New Zealand 
Department of Conservation (DOC), affirming the New Zealand 
government's commitment to the long-term viability of Hector's dolphins 
and indicating that the DOC and the Ministry for Primary Industries 
(MPI) will be undertaking a review of their Threat Management Plan in 
2018. The effectiveness of existing protections for the dolphins will 
be assessed as part of that review. However, we cannot speculate on 
whether or what changes to existing protections may occur in the future 
as a result of that review process.
    During our search for additional information, we noticed that since 
publication of the proposed rule to list SI Hector's dolphins in 
September 2016 (81 FR 64110), five SI Hector's dolphin mortalities had 
been added to the DOC's incident database. Cause of death, which was 
determinable for three of the five dolphins, is listed as disease for 
two dolphins and bycatch in a commercial trawl net for the third 
dolphin. We also found a recent press release, dated June 27, 2017, 
from the New Zealand MPI indicating that MPI was investigating the 
death of two other SI Hector's dolphins found in March 2017, one near 
Banks Peninsula on the East Coast and one in Greymouth on the West 
Coast (http://www.mpi.govt.nz). In the press release, MPI states they 
believe the cause of death of the dolphin found on the West Coast was 
illegal recreational set-netting. This additional information clearly 
indicates that bycatch of SI Hector's dolphins is continuing in both 
trawls and gillnets; however, it does not constitute sufficient data to 
alter or revise our previous assessment. Ultimately, after careful 
consideration, we did not find any basis to change our previous 
conclusion regarding the adequacy of existing bycatch management 
measures. We find that the weight of the available data and study 
results support a conclusion that bycatch has contributed to a large 
historical decline in abundance and continues to contribute to the 
decline of SI Hector's dolphins.
    We agree with the Commission that the population-level effects of 
disease

[[Page 43706]]

and tourism are uncertain. Other threats discussed in our status review 
report (Manning and Grantz 2017)--for example, pollution and 
contaminants--have a similar uncertainty. We do not agree, however, 
that this uncertainty means these threats can be disregarded. As we 
discuss in our status review report, the available data suggest that 
tourism activities and disease are posing threats to SI Hector's 
dolphins (Manning and Grantz 2017). The report presents the available 
information regarding infectious disease cases (especially 
toxoplasmosis) in SI Hector's dolphins, which in addition to being a 
possibly substantial source of mortality, may have other detrimental, 
sub-lethal consequences (e.g., increased risk of predation, reduced 
reproductive rate, neonatal deaths) for the dolphins. The status review 
report also presents information on the intensity and popularity of 
dolphin watching and commercial encounter (or ``swim with'') operations 
off the South Island; and presents evidence of short-term behavioral 
responses in SI Hector's dolphins, and evidence of linkages to longer-
term impacts in other dolphins (e.g., Tursiops sp.). Available data on 
the related concern of boat strikes were also provided. We noted in the 
report that the available data are not currently sufficient to 
understand the magnitude or overall impact of these threats on the 
subspecies. In our proposed rule (81 FR 64123, September 19, 2016), we 
concluded that factors such as disease and tourism are ``lesser 
threats'' that are ``likely exacerbating the rates of decline'' for SI 
Hector's dolphins. In other words, we do not consider disease and 
tourism to be the main drivers of decline of SI Hector's dolphins; 
rather, we consider them to be contributors to the cumulative, negative 
impacts on the status of the subspecies.
    Lastly, we disagree with the suggestion that we should explore the 
possibility of listing separate distinct population segments (DPS) of 
SI Hector's dolphins or consider how their individual statuses might 
contribute to a threatened listing for the subspecies. Section 3 of the 
ESA defines a ``species'' to include ``any subspecies of fish or 
wildlife or plants, and any distinct population segment of any species 
of vertebrate fish or wildlife which interbreeds when mature.'' A joint 
policy with the U.S. Fish and Wildlife Service (together the 
``Services'') lays out two elements that must be considered when 
identifying a DPS: (1) The discreteness of the population segment in 
relation to the remainder of the species (or subspecies); and (2) the 
significance of the population segment to the remainder of the species 
(or subspecies) (``the DPS Policy,'' 61 FR 4722, February 7, 1996). As 
stated in the DPS Policy, Congress expressed its expectation that the 
Services would exercise authority with regard to DPSs sparingly and 
only when the biological evidence indicates such action is warranted. 
In this particular case, because we reached a determination that the SI 
Hector's dolphin warrants listing at the subspecies level, such an 
analysis would be superfluous. In addition, because we were not 
petitioned to list the SI Hector's dolphins as separate DPSs, there is 
no requirement that we commit additional agency resources to conduct an 
analysis and determine whether SI Hector's dolphins could be listed 
separately at the DPS level. Furthermore, we note there is no clear 
conservation benefit to the subspecies by pursuing such an option.
    Comment 5: Several commenters stated that they were opposed to the 
elimination of swim-with-dolphin activities. One commenter stated that, 
although he is supportive of marine mammal conservation generally, 
swimming with wild dolphins should not be prohibited because it causes 
no harm to the dolphins.
    Response: This rulemaking concerns only whether Maui dolphins and 
SI Hector's dolphins meet the statutory definition of a threatened or 
endangered species and thus warrant listing under the ESA. Therefore, 
these comments are not relevant to this rulemaking. Furthermore, 
regulation of swimming with wild Hector's dolphins is under the 
exclusive jurisdiction of the government of New Zealand.
    We also note that, as discussed in our proposed rule and status 
review, several studies have demonstrated short-term behavioral changes 
in SI Hector's dolphins in response to dolphin-watching tour boats and 
`swim-with' activities (e.g., significant disruptions of diving and 
travelling), and that any longer-term impacts are not yet clear. The 
commenter provided no data or information to support the assertion that 
such activities pose ``no harm'' to SI Hector's dolphins.
    Comment 6: Over a dozen commenters requested that the United States 
or U.S. citizens stop buying New Zealand fish until both Maui and SI 
Hector's dolphins are protected throughout their ranges. Several 
comments specifically referenced the Fish and Fish Product Import 
Provisions of the Marine Mammal Protection Act and the associated 
regulatory requirements for countries wishing to export fish to the 
United States. One of these commenters stated that to meet these 
requirements New Zealand will have to implement effective measures to 
protect Maui and Hector's dolphins, including substantially improving 
its fisheries management systems.
    Response: This rulemaking concerns only whether Maui dolphins and 
SI Hector's dolphins meet the statutory definition of a threatened or 
endangered species and thus warrant listing under the ESA. Listing the 
Maui dolphin and the SI Hector's dolphin under the ESA will not 
directly result in a ban or prohibition on U.S. import of fish or fish 
products from fisheries contributing to incidental mortality or serious 
injury of Hector's dolphins. Such a ban cannot be established under the 
authority of the ESA. Specific protections that will be provided to 
Hector's dolphins following their listing under the ESA are discussed 
below in the Effects of Listing section.
    U.S. import of fish or fish products from a nation's fisheries with 
associated incidental mortality or serious injury of marine mammals may 
be subject to NMFS' recent regulation promulgated under the U.S. Marine 
Mammal Protection Act (81 FR 54390, August 15, 2016). This regulation 
established criteria and a formal process for evaluating foreign 
fisheries and their frequency of incidental mortality and serious 
injury of marine mammals. Additional information on this regulation and 
its implementation are available online at www.fisheries.noaa.gov/ia/slider_stories/2016/08/mmpafinalrule.html.
    Comment 7: Multiple commenters raised concerns about the impacts to 
Hector's dolphins from offshore oil and gas development and alternative 
energy projects. One commenter stated that there are concerns that 
current seismic mapping will scare away Hector's dolphins on the east 
coast of the South Island. Another commenter stated that we should 
further consider emerging threats, including the potential offshore 
expansion of renewable energy facilities. This commenter noted that 
while her organization is not opposed to renewable energy projects and 
that while relevant data are limited, the risks to Hector's dolphins 
stemming from pile driving noise, collisions with tidal turbines, 
increased marine traffic, vessel strikes, and habitat displacement 
should not be dismissed. The commenter provided several studies 
documenting the effects of wind farm construction and operation on 
harbor porpoises within the Baltic Sea.
    Response: We agree that seismic testing and other activities within 
the

[[Page 43707]]

marine environment associated with oil and gas exploration and 
development may be posing threats to Hector's dolphins. Our status 
review (Manning and Grantz 2017) provided some discussion about the 
possible impacts of these activities--for example, reductions in local 
fish abundance (Eng[aring]s et al., 1996), disruption of normal 
behaviors (Gordon et al., 2003; Thompson 2012), and habitat 
displacement (Hildebrand 2005). However, we also acknowledged that the 
extent to which Hector's dolphins are being negatively affected--both 
individually and at a population level--has not yet been established 
because there are insufficient data to evaluate impacts to Hector's 
dolphins specifically. Thus, we cannot draw any firm conclusions 
regarding the extent to which these activities are affecting Hector's 
dolphins. We note that the Marine Mammal Impact Assessments, which are 
prerequisite environmental assessments for conducting seismic testing 
within New Zealand's EEZ (http://www.doc.govt.nz/our-work/seismic-surveys-code-of-conduct/marine-mammal-impact-assessments/), typically 
conclude that impacts on marine mammals from seismic testing are 
``minor.''
    In response to the comment on marine renewable energy facilities 
and projects, we reviewed the literature submitted and conducted a 
search for additional information regarding these types of projects 
within New Zealand. According to the national energy efficiency 
strategy for 2017-2022, New Zealand has set a target of generating 90 
percent of its electricity from renewable sources by the year 2025 
(MBIE 2017). However, very little information is available regarding 
specific renewable marine energy projects or associated impacts in New 
Zealand. Tidal and wave energy development, in particular, appear to be 
at a very nascent stage. The Energy Efficiency and Conservation 
Authority (EECA) is New Zealand's government agency charged with 
promoting energy efficiency, including the use of renewable sources of 
energy. According to EECA's Web site, the agency provided funding to 
support six wave or tidal projects from 2007 to 2011 but none of those 
projects has proceeded past some initial stage. A tidal power project 
has been proposed for the main channel of Kaipara Harbor, which lies 
towards the northern edge of the Maui dolphin range; however, the 
status of that facility is unclear. Within the range of SI Hector's 
dolphins, as of 2011, two tidal energy projects were being pursued in 
Cook Strait, and research and development to support a wave energy 
project in Pegasus Bay was underway (Wright and Leary 2011). The 
current status of these projects is also unclear. The EECA Web site 
states that, given the relatively substantial expense of these 
projects, the agency does not foresee marine energy as a major energy 
contributor in New Zealand (see www.eeca.govt.nz). Wind energy appears 
to be a more promising renewable energy source in New Zealand, and 
according to the EECA, 19 wind farms are either operating or under 
construction. However, none of these wind farms are in the marine 
environment (see www.windenergy.org.nz). Therefore, at this time, there 
is insufficient information to evaluate whether renewable marine energy 
projects are currently posing a threat to Hector's dolphins, and there 
is no clear indication that renewable energy projects will pose a 
future threat to the dolphins or their habitat. We have revised our 
status review report to include a discussion of renewable energy 
development, but ultimately this information did not alter our 
extinction risk conclusions for either subspecies.

Summary of Changes From the Proposed Listing Rule

    We did not receive, nor did we find, data or references that 
presented substantial new information to change our proposed listing 
determinations. We did, however, make several revisions to the status 
review report (Manning and Grantz 2017) to incorporate, as appropriate, 
relevant information received in response to our request for public 
comments. Specifically, we updated the status review to include the 
more recently completed 2015-2016 abundance estimate for Maui dolphins 
and associated results (e.g., survival rates, Baker et al., 2016). 
Because this new abundance estimate still indicates a critically low 
population abundance of 63 dolphins 1 year of age and older (95 percent 
CI = 57-75; Baker et al., 2016) and is within the 95 percent confidence 
interval of the previous estimate (N = 55, 95 percent CI = 48-69), it 
did not alter the outcome of our risk assessment. We expanded our 
discussion of population structure within the SI Hector's dolphin to 
include the additional references provided by a commenter and made 
minor edits to clarify our discussion on the rate of decline for this 
subspecies. We also revised the status review report by adding a 
discussion of the potential threat of marine alternative energy 
projects to both Hector's and Maui dolphins. As noted above, 
consideration of this additional, potential threat did not alter any 
conclusions regarding extinction risk for either subspecies. Lastly, we 
updated the spelling of the common name for C. hectori maui to Maui in 
response to a peer reviewer's comment that this spelling more 
appropriately reflects the Maori language from which the name was 
derived.

Status Review

    Status reviews for the Maui dolphin and the SI Hector's dolphin 
were completed by NMFS staff from the Office of Protected Resources. To 
complete the status reviews, we compiled the best available data and 
information on the subspecies' biology, ecology, life history, threats, 
and conservation status by examining the petition and cited references 
and by conducting a comprehensive literature search and review. We also 
considered information submitted to us in response to our petition 
finding. The status review report provides a thorough discussion of the 
life history, threats, demographic risks, and overall extinction risk 
for both dolphin subspecies. The status review was subjected to peer 
review by three, independent reviewers. All peer reviewer comments are 
available at http://www.cio.noaa.gov/services_programs/prplans/ID351.html. The final status review report (cited as Manning and Grantz 
2017) is available on our Web site http://www.nmfs.noaa.gov/pr/species/petition81.htm.

ESA Section 4(a)(1) Factors Affecting the Dolphins

    As stated previously and as discussed in the proposed rule (81 FR 
64110; September 19, 2016), we considered whether any one or a 
combination of the five threat factors specified in section 4(a)(1) of 
the ESA are contributing to the extinction risk of the Maui and SI 
Hector's dolphins. Several commenters provided additional information 
related to threats such as forms of habitat modification and 
degradation, under-reporting of bycatch, and the projected population 
decline of SI Hector's dolphins. The information provided was 
consistent with or reinforced information in the status review report 
and proposed rule, and thus, did not change our conclusions regarding 
any of the section 4(a)(1) factors or their interactions. Therefore, we 
incorporate herein all information, discussion, and conclusions 
regarding the factors affecting the two dolphin subspecies from the 
final status review report (Manning and Grantz 2017) and the

[[Page 43708]]

proposed rule (81 FR 64110; September 19, 2016).

Extinction Risk

    As discussed previously, the status review evaluated the 
demographic risks to both dolphin subspecies according to four 
categories--abundance and trends, population growth/productivity, 
spatial structure/connectivity, and genetic diversity. As a concluding 
step, after considering all of the available information regarding 
demographic and other threats to the subspecies, we rated each 
subspecies' extinction risk according to a qualitative scale (high, 
moderate, and low risk). Although we did update our status review to 
incorporate the most recent abundance estimate for Maui dolphins and 
information from two additional studies regarding population 
fragmentation within SI Hector's dolphins, none of the comments or 
information we received on the proposed rule changed the outcome of our 
extinction risk evaluations for either subspecies. Our conclusions 
regarding extinction risk for these subspecies remain the same. 
Therefore, we incorporate herein all information, discussion, and 
conclusions on the extinction risk of the two dolphin subspecies in the 
final status review report (Manning and Grantz 2017) and proposed rule 
(81 FR 64110; September 19, 2016).

Protective Efforts

    In addition to regulatory measures (e.g., fishing and boating 
regulations, sanctuary designations), we considered other efforts being 
made to protect Hector's dolphins. We considered whether such 
protective efforts altered the conclusions of the extinction risk 
analysis for Maui and SI Hector's dolphins. None of the information we 
received on the proposed rule affected our conclusions regarding 
conservation efforts to protect the two dolphin subspecies. Therefore, 
we incorporate herein all information, discussion, and conclusions on 
the extinction risk of the two dolphin subspecies in the final status 
review report (Manning and Grantz 2017) and proposed rule (81 FR 64110; 
September 19, 2016).

Final Listing Determinations

    The present estimated abundance of Maui dolphins is critically low, 
and the subspecies faces additional demographic risks due to greatly 
reduced genetic diversity and a low intrinsic population growth rate. 
Past declines, estimated to be on the order of about 90 percent 
(Martien et al., 1999, Slooten 2007a), are considered to have been 
driven largely by bycatch in gillnets (Currey et al., 2012). Maui 
dolphins continue to face threats of bycatch, disease, and mining and 
seismic disturbances; and, it is considered unlikely that this 
subspecies will recover unless sources of anthropogenic mortality are 
eliminated (Slooten et al., 2006; MFish and DOC 2007b, Baker et al., 
2010). Based on the best available scientific and commercial 
information, as summarized here, in our proposed rule (81 FR 64110; 
September 19, 2016), and in the status review report (Manning and 
Grantz 2017), and after consideration of protective efforts, we find 
that the Maui dolphin (Cephalorhynchus hectori maui) is in danger of 
extinction throughout its range. Therefore, we find that this 
subspecies meets the definition of an endangered species under the ESA 
and list it as such.
    The SI Hector's dolphin has experienced substantial population 
declines since the 1970s, has relatively low genetic diversity, a low 
intrinsic population growth rate, and a fragmented population 
structure. Although historical data are lacking, Slooten (2007a) 
estimated that the SI Hector's dolphin population has declined by about 
73 percent between 1970 and 2007, and available population viability 
analyses indicate that the SI Hector's dolphin is likely to continue to 
decline unless bycatch mortality is reduced (Davies et al., 2008, 
Slooten and Davies 2012, Slooten 2013). Gormley et al. (2012) estimated 
that the Banks Peninsula population, which has benefited from almost 
three decades of protection, would continue to decline at a rate of 
about 0.5 percent per year despite significantly improved survival 
rates. The actual rate of decline of the subspecies remains unclear 
given the very limited bycatch mortality data available, and a trend 
analysis based on survey data is also confounded by the fact that 
surveys have covered different portions of the range and have 
dramatically increased in sophistication and geographical scope over 
time. Thus, a precise analysis of the rate of decline and projection of 
time to extinction given multiple threats and demographic 
considerations is not currently possible. However, the available 
evidence indicates that management measures have not halted population 
declines and supports a conclusion that populations of SI Hector's 
dolphins will continue to decline.
    Current levels of bycatch are contributing to the decline of this 
subspecies (Slooten and Davies 2012). Additional, lesser threats, such 
as disease and tourism impacts, are likely exacerbating the rate of 
decline and thereby contributing to the overall extinction risk of this 
subspecies. Given recent abundance estimates for the total population 
and evidence of a slowed rate of decline following expanded fisheries 
management measures, we find that this subspecies is not presently in 
danger of extinction. However, significant historical declines and the 
projected decline for most populations, combined with a low population 
growth rate, low genetic diversity, limited population connectivity, 
and the ongoing threats of bycatch, disease, and tourism, provide a 
strong indication that this subspecies is likely to become an 
endangered species within the foreseeable future. We therefore find 
that this subspecies meets the definition of threatened under the ESA 
and list it as such.

Effects of Listing

    Conservation measures provided for species listed as endangered or 
threatened under the ESA include the development and implementation of 
recovery plans (16 U.S.C. 1533(f)); designation of critical habitat, if 
prudent and determinable (16 U.S.C. 1533(a)(3)(A)); and a requirement 
that Federal agencies consult with NMFS under section 7 of the ESA to 
ensure their actions are not likely to jeopardize the species or result 
in adverse modification or destruction of designated critical habitat 
(16 U.S.C. 1536). For endangered species, protections also include 
prohibitions related to ``take'' and trade (16 U.S.C. 1538). Take is 
defined as ``to harass, harm, pursue, hunt, shoot, wound, kill, trap, 
capture, or collect, or to attempt to engage in any such conduct'' (16 
U.S.C. 1532(19)). These prohibitions do not apply to species listed as 
threatened unless protective regulations are issued under section 4(d) 
of the ESA (16 U.S.C. 1533(d)), leaving it to the Secretary's 
discretion whether, and to what extent, to extend the ESA's 
prohibitions to the species. Section 4(d) protective regulations may 
prohibit, with respect to threatened species, some or all of the acts 
which section 9(a) of the ESA prohibits with respect to endangered 
species.
    Recognition of the species' imperiled status through listing may 
also promote conservation actions by Federal and state agencies, 
foreign entities, private groups, and individuals.

Activities That Would Constitute a Violation of Section 9 of the ESA

    On July 1, 1994, NMFS and the U.S. Fish and Wildlife Service 
(USFWS) published a policy (59 FR 34272) that requires us to identify, 
to the maximum

[[Page 43709]]

extent practicable at the time a species is listed, those activities 
that would or would not constitute a violation of section 9 of the ESA. 
The intent of this policy is to increase public awareness of the 
potential effects of species listings on proposed and ongoing 
activities.
    Because we are listing the Maui dolphin as endangered, all of the 
prohibitions of section 9(a)(1) of the ESA will apply to this 
subspecies. Section 9(a)(1) includes prohibitions against the import, 
export, use in foreign commerce, and ``take'' of the listed species. 
These prohibitions apply to all persons subject to the jurisdiction of 
the United States, including in the United States, its territorial sea, 
or on the high seas. Activities that could result in a violation of 
section 9 prohibitions for Maui dolphins include, but are not limited 
to, the following:
    (1) Delivering, receiving, carrying, transporting, or shipping in 
interstate or foreign commerce any Maui dolphin or any of its parts, in 
the course of a commercial activity;
    (2) Selling or offering for sale in interstate commerce any part, 
except antique articles at least 100 years old; and
    (3) Importing or exporting Maui dolphins or any parts of these 
dolphins.
    Whether a violation results from a particular activity is entirely 
dependent upon the facts and circumstances of each incident. Further, 
an activity not listed here may in fact constitute a violation.

Identification of Those Activities That Would Not Likely Constitute a 
Violation of Section 9 of the ESA

    Although the determination of whether any given activity 
constitutes a violation is fact dependent, we consider the following 
actions, depending on the circumstances, as being unlikely to violate 
the prohibitions in ESA section 9 with regard to Maui dolphins: (1) 
Take authorized by, and carried out in accordance with the terms and 
conditions of, an ESA section 10(a)(1)(A) permit issued by NMFS for 
purposes of scientific research or the enhancement of the propagation 
or survival of the species; and (2) continued possession of Maui 
dolphins or any parts that were in possession at the time of listing. 
Such parts may be non-commercially exported or imported; however, the 
importer or exporter must be able to provide evidence to show that the 
parts meet the criteria of ESA section 9(b)(1) (i.e., held in a 
controlled environment at the time of listing, in a non-commercial 
activity).
    Section 11(f) of the ESA gives NMFS the authority to promulgate 
regulations that may be appropriate to enforce the ESA. Thus, we could 
promulgate future regulations to regulate trade or holding of Maui 
dolphins. However, we do not foresee a necessity for such regulations 
at this time.

Protective Regulations Under Section 4(d) of the ESA

    Because we are listing the SI Hector's dolphins as threatened, the 
prohibitions under section 9 of the ESA will not automatically apply to 
this subspecies. As stated above, ESA section 4(d) leaves it to the 
Secretary's discretion whether, and to what extent, to extend the 
section 9(a) prohibitions to threatened species, and authorizes us to 
issue regulations that are deemed necessary and advisable to provide 
for the conservation of the species. Because SI Hector's dolphins occur 
entirely outside of the United States, and are not commercially traded 
with the United States, extending the section 9(a) prohibitions to this 
subspecies will not result in added conservation benefits or species 
protection, particularly given the fact that such trade is already 
generally prohibited under the Marine Mammal Protection Act (16 U.S.C. 
1372). Therefore, we do not intend to issue section 4(d) regulations 
for SI Hector's dolphins at this time.

Section 7 Consultation Requirements

    Section 7(a)(2) (16 U.S.C. 1536(a)(2)) of the ESA and joint NMFS/
USFWS regulations require Federal agencies to consult with NMFS to 
ensure that activities they authorize, fund, or carry out are not 
likely to jeopardize the continued existence of listed species or 
destroy or adversely modify critical habitat. It is unlikely that the 
listing of these subspecies under the ESA will increase the number of 
section 7 consultations, because these subspecies occur outside of the 
United States and are unlikely to be affected by U.S. Federal actions.

Critical Habitat

    Critical habitat is defined in section 3 of the ESA (16 U.S.C. 
1532(5)) as: (1) The specific areas within the geographical area 
occupied by a species, at the time it is listed in accordance with the 
ESA, on which are found those physical or biological features (a) 
essential to the conservation of the species and (b) that may require 
special management considerations or protection; and (2) specific areas 
outside the geographical area occupied by a species at the time it is 
listed if such areas are determined to be essential for the 
conservation of the species. Section 4(a)(3)(A) of the ESA (16 U.S.C. 
1533(a)(3)(A)) requires that, to the extent prudent and determinable, 
critical habitat be designated concurrently with the listing of a 
species. However, critical habitat cannot be designated in foreign 
countries or other areas outside U.S. jurisdiction (50 CFR 424.12(g)). 
Maui and SI Hector's dolphins are endemic to New Zealand and do not 
occur within areas under U.S. jurisdiction. There is no basis to 
conclude that any unoccupied areas under U.S. jurisdiction are 
essential for the conservation of either subspecies. Therefore, we do 
not intend to propose any critical habitat designations for either 
subspecies.

Peer Review

    In December 2004, the Office of Management and Budget (OMB) issued 
a Final Information Quality Bulletin for Peer Review establishing a 
minimum peer review standard. We solicited peer review comments on the 
draft status review report from three scientists with expertise on 
Hector's dolphins. We received and reviewed comments from these 
scientists, and, prior to publication of the proposed rule, their 
comments were incorporated into the draft status review report (Manning 
and Grantz 2016), which was then made available for public comment. As 
stated earlier, peer reviewer comments on the status review are 
available at http://www.cio.noaa.gov/services_programs/prplans/ID351.html.

Classification

National Environmental Policy Act

    Section 4(b)(1)(A) of the ESA restricts the information that may be 
considered when assessing species for listing and sets the basis upon 
which listing determinations must be made. Based on the requirements in 
section 4(b)(1)(A) of the ESA and the opinion in Pacific Legal 
Foundation v. Andrus, 675 F. 2d 825 (6th Cir. 1981), we have concluded 
that ESA listing actions are not subject to the environmental 
assessment requirements of the National Environmental Policy Act 
(NEPA).

Executive Order 12866, Regulatory Flexibility Act

    As noted in the Conference Report on the 1982 amendments to the 
ESA, economic impacts cannot be considered when assessing the status of 
a species. Therefore, the economic analysis requirements of the 
Regulatory

[[Page 43710]]

Flexibility Act are not applicable to the listing process.
    In addition, this rule is exempt from review under Executive Order 
12866.

Paperwork Reduction Act

    This final rule does not contain a collection-of-information 
requirement for the purposes of the Paperwork Reduction Act.

Executive Order 13132, Federalism

    In accordance with E.O. 13132, we determined that this final rule 
does not have significant federalism effects and that a federalism 
assessment is not required.
