significant new information regarding the species' taxonomic status as 
presented by the American Fisheries Society and the American Society of 
Ichthyologists and Herpetologists (AFS/ASIH) Joint Committee on the 
Names of Fishes. We are reopening the comment period for 45 days to 
provide the public additional time to review and consider our proposed 
rulemakings in light of this new information.

DATES: The comment period end date for the proposed rule that published 
at 80 FR 60754 on October 7, 2015, is December 16, 2016. We request 
that comments be submitted by 11:59 p.m. Eastern Time on the closing 
date.

ADDRESSES: Comment submission: You may submit comments by one of the 
following methods:
    (1) Electronically: Go to the Federal eRulemaking Portal: http://www.regulations.gov. In the Search box, enter the appropriate Docket 
No.: FWS- R2-ES-2015-0148 for the proposed threatened status for 
headwater chub and the roundtail chub distinct population segment. You

SUPPLEMENTARY INFORMATION: 

Previous Federal Actions

    On October 7, 2015 (80 FR 60754), we published a proposed rule that 
the headwater chub and the lower Colorado River basin roundtail chub 
DPS are threatened species under the Endangered Species Act of 1973, as 
amended (Act) (16 U.S.C. 1531 et seq.). Section 4(b)(6)(A) of the Act 
requires that we make final listing determinations within 1 year of the 
proposed rule, except where, as in this instance, there is substantial 
disagreement regarding the sufficiency or accuracy of the available 
data, which allows for an additional 6 months. On August 15, 2016 (81 
FR 54018), we announced a 6-month extension on the proposed rule's 
final determination due to substantial disagreement regarding the 
available data's sufficiency or accuracy, and reopened the comment 
period for 30 days. Accordingly, the deadline to finalize or withdraw 
the proposed rule is April 7, 2017. For a description of additional 
previous Federal actions concerning these species, please refer to the 
proposed listing rule (October 7, 2015; 80 FR 60754).

Background

    In the proposed rule (October 7, 2015; 80 FR 60754), we evaluated 
headwater and roundtail chubs as separate species. However, commenters 
raised questions regarding the headwater and roundtail chubs' taxonomic 
distinctness, as related to one another and to the Gila chub (Gila 
intermedia). The Gila chub is listed as an endangered species (November 
2, 2005; 70 FR 66664). Some scientists knowledgeable about the species 
contend that the three entities are not separate species.
    For this reason, the Arizona Game and Fish Department requested 
that the AFS/ASIH evaluate the most recent literature associated with 
roundtail chub, headwater chub, and Gila chub taxonomy. The AFS/ASIH is 
recognized as the authority in establishing the taxonomic status of 
fish. The panel met in April 2016 and again in August 2016, and 
presented their conclusions in a final report to the Arizona Game and 
Fish Department on September 1, 2016 (Page et al. 2016; see Docket No. 
FWS-R2-ES-2015-0148 at http://www.regulations.gov). The AFS/ASIH review 
(Page et al. 2016) included published and unpublished studies and 
reports presented to them in April 2016, and a more recent, unpublished 
report by Copus et al. (2016), which was included as an appendix to 
Page et al. (2016). Based on the information reviewed, the AFS/ASIH 
panel concluded that ``no morphological or genetic data define 
populations of Gila in the lower Colorado River basin (which includes 
the Little Colorado River, Bill Williams River, Gila River, Verde 
River, and Salt River drainages) as members of more than one species'' 
and ``that the data available support recognition of only one species 
of Gila, the roundtail chub, Gila robusta'' (Page et al. 2016). This 
new information could be of significant consequence in our final 
listing determination because our proposed rule reviewed these entities 
as separate species. Given the new information, we must now review the 
proposed entities' validity as recognized species. Further, this 
information was not previously included or considered in our proposed 
rulemaking or made available to the public. Therefore, we are reopening 
the comment period for 45 days to allow consideration of this new 
information, as well as any other aspect of the proposed rule, prior to 
finalizing our decision.

Public Comments

    We will accept written comments and information during this 
reopened comment period on our proposed headwater chub and roundtail 
chub DPS listing published in the Federal Register on October 7, 2015 
(80 FR 60754). We will consider information and recommendations from 
all interested parties. We intend that any final action resulting from 
these proposals be as accurate as possible and based on the best 
available scientific and commercial data.
    In considering the new information received from the AFS/ASIH, as 
well as the information provided in the proposed rule, we are 
particularly seeking comments considering:
    (a) Roundtail, headwater, and Gila chub genetics and taxonomy;
    (b) Roundtail, headwater, and Gila chubs' morphological 
characteristics;
    (c) Those topics previously noted in the October 7, 2015, proposed 
rule (see 80 FR 60754).
    If you previously submitted comments or information on the proposed 
rule, please do not resubmit them. We have incorporated them into the 
public record, and we will fully consider them in preparing our final 
determinations. Our final determinations will take into consideration 
all written comments and any additional information we received.
    You may submit your comments and materials concerning this proposed 
rule by one of the methods listed above in ADDRESSES. We request that 
you send comments only by the methods described in ADDRESSES.
    If you submit information via http://www.regulations.gov, your 
entire submission--including any personal identifying information--will 
be posted on the Web site. If your submission is made via a hardcopy 
that includes personal identifying information, you may request at the 
top of your document that we withhold this information from public 
review. However, we cannot guarantee that we will be able to do so. We 
will post all hardcopy submissions on http://www.regulations.gov.
    Comments and materials we receive, as well as supporting 
documentation we used in preparing the proposed rule, will be available 
for public inspection on http://www.regulations.gov, or by appointment, 
during normal business hours, at the U.S. Fish and Wildlife Service, 
Arizona Ecological Services Field Office (see FOR FURTHER INFORMATION 
CONTACT). You may obtain copies of the proposed rule on the Internet at 
http://www.regulations.gov at Docket No. FWS-R2-ES-2015-0148. Copies of 
the proposed rule are also available at http://www.fws.gov/southwest/es/arizona.
