Abstract

We, the U.S. Fish and Wildlife Service (Service), propose to revise regulations issued under section 4(e) of the Endangered Species Act (Act) related to furthering the conservation of the following listed endangered species and threatened species: Pearl River map turtle (Graptemys pearlensis), bog turtle (northern distinct population segment [DPS]) (Glyptemys muhlenbergii), Miami blue butterfly (Cyclargus thomasi bethunebakeri), Desert tortoise (Mojave DPS) (Gopherus agassizii), Florida panther (Puma (=Felis) concolor coryi), and pallid sturgeon (Scaphirhynchus albus). We propose to amend or remove regulations concerning taking or commerce in the following 11 similarity of appearance species: Alabama map turtle (Graptemys pulchra), Barbour's map turtle (Graptemys barbouri), Escambia map turtle (Graptemys ernsti), Pascagoula map turtle (Graptemys gibbonsi), bog turtle (southern DPS), cassius blue butterfly (Leptotes cassius theonus), ceraunus blue butterfly (Hemiargus ceraunus antibubastus), nickerbean blue butterfly (Cyclargus ammon), desert tortoise (Sonoran population), puma (=mountain lion) (Puma (=Felis) concolor (all subspecies except coryi)), and shovelnose sturgeon (Scaphirhynchus platorynchus). We are proposing these changes to eliminate unnecessary regulations and to ensure that species treated as endangered or threatened under section 4(e) of the Act meet the three required criteria as directed in section 4(e) of the Act.

Endangered and Threatened Wildlife and Plants; Regulations for 
Eleven Species Treated as Listed Due to Similarity of Appearance

AGENCY: U.S. Fish and Wildlife Service, Interior.

ACTION: Proposed rule.

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

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to 
revise regulations issued under section 4(e) of the Endangered Species 
Act (Act) related to furthering the conservation of the following 
listed endangered species and threatened species: Pearl River map 
turtle (Graptemys pearlensis), bog turtle (northern distinct population 
segment [DPS]) (Glyptemys muhlenbergii), Miami blue butterfly 
(Cyclargus thomasi bethunebakeri), Desert tortoise (Mojave DPS) 
(Gopherus agassizii), Florida panther (Puma (=Felis) concolor coryi), 
and pallid sturgeon (Scaphirhynchus albus). We propose to amend or 
remove regulations concerning taking or commerce in the following 11 
similarity of appearance species: Alabama map turtle (Graptemys 
pulchra), Barbour's map turtle (Graptemys barbouri), Escambia map 
turtle (Graptemys ernsti), Pascagoula map turtle (Graptemys gibbonsi), 
bog turtle (southern DPS), cassius blue butterfly (Leptotes cassius 
theonus), ceraunus blue butterfly (Hemiargus ceraunus antibubastus), 
nickerbean blue butterfly (Cyclargus ammon), desert tortoise (Sonoran 
population), puma (=mountain lion) (Puma (=Felis) concolor (all 
subspecies except coryi)), and shovelnose sturgeon (Scaphirhynchus 
platorynchus). We are proposing these changes to eliminate unnecessary 
regulations and to ensure that species treated as endangered or 
threatened under section 4(e) of the Act meet the three required 
criteria as directed in section 4(e) of the Act.

SUPPLEMENTARY INFORMATION:

Information Requested

    We intend that any final action resulting from this proposed rule 
will be based on the best scientific and commercial data available and 
be as accurate and as effective as possible. Therefore, we request 
comments or information from other governmental agencies, Native 
American Tribes, the scientific community, industry, or any other 
interested parties concerning this proposed rule. We particularly seek 
comments concerning:
    (1) Threats and conservation actions affecting the species listed 
under section 4(a) of the Act and whether the similarity of appearance 
regulations under section 4(e) concerning treatment of the unlisted 
4(e) species addressed in this proposed rulemaking are needed to 
address these threats and conservation actions in accordance with 
section 4(e).
    (2) Information to assist us with applying or issuing regulations 
under section 4(e) of the Act concerning treatment of the following 
species addressed in this proposed rulemaking (Alabama map turtle, 
Barbour's map turtle, Escambia map turtle, Pascagoula map turtle, 
southern DPS of bog turtle, and Sonoran DPS of desert tortoise). In 
particular, we seek information concerning:
    (a) The extent to which we should include any of the Act's section 
9(a) prohibitions in the 4(e) regulations; and
    (b) Whether we should consider any additional or different 
exceptions from the prohibitions in the 4(e) regulations.

[[Page 46372]]

    (3) Potential impacts on the Miami blue butterfly, Florida panther, 
and pallid sturgeon from proposed removal of 4(e) treatment for the 
cassius blue butterfly, ceraunus blue butterfly, nickerbean blue 
butterfly, puma, and shovelnose sturgeon.
    (4) Potential impacts on regulated entities from the proposed 
rulemaking.
    (5) Potential impacts on the Pearl River map turtle, bog turtle 
(northern DPS), and Desert tortoise (Mojave DPS) from proposed 
amendment of 4(e) treatment for the Alabama map turtle, Barbour's map 
turtle, Escambia map turtle, Pascagoula map turtle, bog turtle 
(southern DPS), and desert tortoise (Sonoran population).
    Please include any supplemental information with your submission 
(such as scientific journal articles or other publications) to allow us 
to verify any scientific or commercial information you include.
    Please note that submissions merely stating support for, or 
opposition to, the action under consideration without providing 
supporting information, although noted, do not provide substantial 
information necessary to support a determination. Determinations will 
be made in accordance with the criteria in section 4(e) of the Act.
    You may submit your comments and materials concerning this proposed 
rule by one of the methods listed in ADDRESSES. We request that you 
send comments only by the methods described in ADDRESSES.
    If you submit information via <a href="https://www.regulations.gov">https://www.regulations.gov</a>, your 
entire submission--including any personal identifying information--will 
be posted on the website. 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 <a href="https://www.regulations.gov">https://www.regulations.gov</a>.
    Comments and materials we receive, as well as supporting 
documentation we used in preparing this proposed rule, will be 
available for public inspection on <a href="https://www.regulations.gov">https://www.regulations.gov</a>.
    Our final determination may differ from this proposal because we 
will consider all comments we receive during the comment period as well 
as any information that may become available after this proposal. Based 
on the new information we receive (and, if relevant, any comments on 
that new information), we may conclude with respect to each unlisted 
4(e) species addressed in this proposed rulemaking that we should keep 
treating the species as listed under section 4(e) of the Act or no 
longer treat the species as listed under section 4(e) of the Act. In 
addition, we may change the prohibitions or the exceptions to those 
prohibitions in the regulations issued or applied under section 4(e) of 
the Act if we conclude it is appropriate in light of comments and new 
information received. In our final rule, we will clearly explain our 
rationale and the basis for our final decision, including why we made 
changes, if any, that differ from this proposal.

Background

    Section 4 of the Endangered Species Act of 1973, as amended 
(``Act'' or ``ESA''; 16 U.S.C. 1533) and the implementing regulations 
in title 50 of the Code of Federal Regulations (CFR) set forth the 
procedures for determining whether a species is an endangered species 
or a threatened species, issuing protective regulations for threatened 
species, and designating critical habitat for endangered and threatened 
species.
    The Act defines an ``endangered species'' at 16 U.S.C. 1532(6) as a 
species that is in danger of extinction throughout all or a significant 
portion of its range and a ``threatened species'' at 16 U.S.C. 1532(20) 
as a species that is likely to become an endangered species within the 
foreseeable future throughout all or a significant portion of its 
range. The Act requires that we determine whether any species is an 
endangered species or a threatened species because of any of the 
following factors in section 4(a):
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    These factors represent broad categories of natural or human-caused 
actions or conditions that could have an effect on a species' continued 
existence. In evaluating these actions and conditions, we look for 
those that may have a negative effect on individuals of the species, as 
well as other actions or conditions that may ameliorate any negative 
effects or may have positive effects.
    Section 2 of the Act states that the purposes of the Act include 
providing a means to conserve the ecosystems upon which endangered and 
threatened species depend, developing a program for the conservation of 
listed species, and achieving the purposes of certain treaties and 
conventions (16 U.S.C. 1531(b)). The ultimate goal of conservation 
efforts is the recovery of listed species, so that they no longer need 
the protective measures of the Act. The Act provides multiple tools to 
conserve species that warrant protection under section 4(a) and have 
been added to the List of Endangered and Threatened Wildlife (50 CFR 
17.11) or the List of Endangered and Threatened Plants (50 CFR 17.12). 
These include (among other protections) designation of critical 
habitat, recovery planning under section 4(f), protective regulations 
for threatened species under section 4(d), and Federal agency 
requirements to ensure their actions are not likely to jeopardize the 
continued existence of listed species or destroy or adversely modify 
their critical habitat under section 7(a)(2).
    One of these tools, detailed in section 4(e) of the Act, provides 
the Service with the discretion to treat species as endangered species 
or threatened species when they do not meet the definition of an 
endangered species or threatened species (16 U.S.C. 1532(6), (20)) as a 
result of the factors listed in section 4(a). This authority to treat 
species as endangered or threatened when they are similar in appearance 
to (i.e., resemble) a species that is listed under section 4(a) is 
limited to situations when treating the species as endangered or 
threatened under section 4(e) will ``substantially facilitate 
enforcement'' of the Act for the benefit of, and reduce threats to, the 
species listed under section 4(a). The Act's tools and protections for 
endangered and threatened species are directed at the species that meet 
the definitions of endangered species or threatened species under 
section 4(a), not the species that are treated as endangered or 
threatened under section 4(e) solely because of a similarity in 
appearance.
    Section 4(e) of the Act provides that the Secretary may, by 
regulation of commerce or taking, and to the extent he deems advisable, 
treat any species as an endangered species or threatened species even 
though it is not listed pursuant to section 4 of the Act if the 
Secretary finds that: (A) such species so closely resembles in 
appearance, at the point in question, a species which has been listed 
pursuant to the Act that enforcement personnel would have substantial 
difficulty in attempting to differentiate between the listed and 
unlisted species; (B) the effect of this substantial difficulty is an 
additional threat to an endangered or threatened species; and (C) such 
treatment of an

[[Page 46373]]

unlisted species will substantially facilitate the enforcement and 
further the policy of the Act (16 U.S.C. 1533(e)). The Act provides the 
Service discretion in determining both when and how to apply section 
4(e).
    Executive Order (E.O.) 14154, ``Unleashing American Energy,'' 
issued January 20, 2025, directed all departments and agencies to 
immediately review agency actions that potentially impose an undue 
burden on the identification, development, or use of domestic energy 
resources, and, as appropriate and consistent with applicable law, 
consider suspending, revising, or rescinding agency actions that 
conflict with this national objective (90 FR 8353). In addition, E.O. 
14192, ``Unleashing Prosperity Through Deregulation,'' issued January 
31, 2025, is intended to significantly reduce the private expenditures 
required to comply with Federal regulations to secure America's 
economic prosperity and national security and the highest possible 
quality of life for each citizen (90 FR 9065). As E.O. 14192 noted, it 
is important that for each new regulation issued, at least 10 prior 
regulations be identified for elimination. This practice is to ensure 
that the cost of planned regulations is responsibly managed and 
controlled through a rigorous regulatory budgeting process. It is the 
policy of the executive branch to be prudent and financially 
responsible in the expenditure of funds, from both public and private 
sources, and to alleviate unnecessary regulatory burdens placed on the 
American people. This proposed rule is intended to reduce or remove 
regulatory burdens.
    The Service has finalized regulations that treat 17 entities as 
listed species under section 4(e) of the Act. These entities are listed 
as E (S/A) (endangered based on similarity of appearance to an existing 
listed species) or T (S/A) (threatened based on similarity of 
appearance to an existing listed species) at 50 CFR 17.11. After 
reviewing these regulations, we propose to remove or revise this 
treatment for 11 species.

Proposed Regulatory Revisions

    We propose to remove treatment as listed species for the following 
five unlisted species: cassius blue butterfly, ceraunus blue butterfly, 
nickerbean blue butterfly, puma, and shovelnose sturgeon. We also 
propose to revise regulations under section 4(e) of the Act for the 
following six unlisted species that are treated as listed species: 
Alabama map turtle, Barbour's map turtle, Escambia map turtle, 
Pascagoula map turtle, southern DPS of bog turtle, and Sonoran DPS of 
desert tortoise. See table 1, below, for a summary of the species and 
proposed actions discussed in this document.

Florida Panther and Puma

    The Florida panther was first listed as an endangered species under 
the precursor to the Act, the Endangered Species Preservation Act of 
October 15, 1966 (16 U.S.C. 668aa(c); 32 FR 4001, March 11, 1967) and 
has continued to be protected as an endangered species under the Act. 
Because unlisted species of cougars (or pumas) periodically occur in 
Florida, either as escapees from captivity or as deliberate releases or 
wild individuals from populations outside of Florida, there is a risk 
that Florida panthers will be killed under the assumption or 
justification that they are escaped cougars or other wild big cats. 
Therefore, we finalized a rule on August 14, 1991 (56 FR 40265), 
treating all other free-living Felis concolor (i.e., puma, mountain 
lion) in Florida (hereafter referred to as ``puma'' or ``mountain 
lion'') as a threatened species under section 4(e) of the Act due to 
similarity of appearance to the Florida panther. We also issued 
regulations at 50 CFR 17.40(h) providing the prohibitions and exception 
for activities with regard to the puma.
    The regulations provide that except as otherwise allowed, no person 
shall take any free-living mountain lion (Felis concolor) in Florida. 
Exceptions allow for a mountain lion to be taken in this area under a 
valid threatened species permit issued pursuant to 50 CFR 17.52 or when 
an employee or designated agent of the Service or the Florida Game and 
Fresh Water Fish Commission takes a mountain lion for taxonomic 
identification or other reasons consistent with the conservation of the 
endangered Florida panther (Felis concolor coryi). When it has been 
established by the Service, in consultation with the State, that an 
animal in question is not a Florida panther or an eastern cougar (Felis 
concolor couguar), such animals may be removed from the wild. The 
disposition of animals so taken shall be at the discretion of the 
Florida Game and Fresh Water Fish Commission, with the concurrence of 
the Service. Take for reasons of human safety is allowed and must be 
reported in writing to the Service's Office of Law Enforcement. The 
specimen may only be retained, disposed of, or salvaged in accordance 
with directions from the Service.
    According to our 2009 status review, habitat loss, fragmentation, 
degradation, and associated human disturbance are the greatest threats 
to panther survival and among the greatest threats to its recovery 
(Service 2009, p. 12).
    We propose to remove section 4(e) similarity of appearance 
treatment for puma as a threatened species at 50 CFR 17.11 together 
with the corresponding 4(e) regulations at 50 CFR 17.40(h). The 
intention of the 4(e) regulations for puma are largely duplicative with 
other

[[Page 46374]]

existing protections for the Florida panther and puma.
    The Florida panther was first declared to be an endangered species 
by the Florida Game and Fresh Water Fish Commission (GFC), the 
predecessor agency of the current Florida Fish and Wildlife 
Conservation Commission (FWC), in 1958, at which time State protections 
were afforded to the species. FWC currently lists the Florida panther 
as a federally designated Endangered Species (68A-27.003, Florida 
Administrative Code). Federally designated Endangered and Threatened 
Species are defined by the State of Florida as ``species of fish or 
wild animal life, subspecies or isolated populations of species or 
subspecies, whether vertebrate or invertebrate, that are native to 
Florida and classified as Endangered and Threatened under Commission 
rule by virtue of designation by the United States Departments of 
Interior or Commerce as endangered or threatened under the Federal 
Endangered Species Act, 16 U.S.C. 1532 et seq. and rules thereto[. . 
.]'' (68A-27.001(2) Florida Administrative Code).
    Florida's regulations provide that ``no person shall take, possess, 
or sell any of the endangered or threatened species included in this 
subsection, or parts thereof or their nests or eggs except as allowed 
by specific federal permit or authorization'' (68A-27.003(1)(a) Florida 
Administrative Code). Take is defined as ``to harass, harm, pursue, 
hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to 
engage in such conduct'' (68A-27.003(4) Florida Administrative Code, 
Title XXVII, section 379.101). Florida statutes also provide that ``it 
is unlawful for a person to kill a member of the Florida `endangered 
species,' as defined in s. 379.2291(3), known as the Florida panther 
(Felis concolor coryi)'' and that ``it is unlawful for a person to kill 
any member of the species of panther (Felis concolor) occurring in the 
wild'' (section 379.4115 Florida Statutes). Any person convicted of 
violating these sections commits a Level Four violation under s. 
379.401.
    This proposal would not alter any protections relating to 
activities with the Florida panther under State or Federal law. Anyone 
under the jurisdiction of the United States that engages in prohibited 
activities with the Florida panther without a permit is subject to law 
enforcement.
    We continue to find that the puma so closely resembles the Florida 
panther in appearance that enforcement personnel would have substantial 
difficulty in attempting to differentiate between the species. However, 
given the protections available in the State of Florida for both the 
Florida panther and puma, the effect of this substantial difficulty is 
not an additional threat to the Florida panther. Because the law 
regarding the killing of any panther does not cite to the protections 
currently afforded by section 4(e) of the Act, we anticipate these 
protections will continue after our proposed removal of such treatment. 
We appreciate and are seeking comments from the State of Florida on 
this proposal. We find that this continued treatment will not 
substantially facilitate the enforcement and the policy of the Act 
because of the current protections under State laws; therefore, 
treating the puma as a threatened species is no longer advisable in 
accordance with section 4(e) because one of the three statutory 
criteria is no longer met.

Miami Blue Butterfly and Cassius Blue Butterfly, Ceraunus Blue 
Butterfly, and Nickerbean Blue Butterfly

    On April 6, 2012, the Service published a final rule (77 FR 20948) 
listing the Miami blue butterfly as an endangered species primarily due 
to habitat loss and fragmentation. In that final rule, we also made 
final determinations to treat the cassius blue butterfly, ceraunus blue 
butterfly, and nickerbean blue butterfly as threatened species due to 
similarity of appearance to the Miami blue butterfly and issued 
regulations at 50 CFR 17.47(a) providing the prohibitions and 
exceptions for the cassius blue butterfly, ceraunus blue butterfly, and 
nickerbean blue butterfly.
    The regulations at 50 CFR 17.47(a) provide that: (1) The provisions 
of Sec.  17.31(c) apply to cassius blue butterfly, ceraunus blue 
butterfly, nickerbean blue butterfly regardless of whether in the wild 
or in captivity, and also apply to the progeny of any such butterfly; 
(2) Any violation of State law will also be a violation of the Act; (3) 
Incidental take, that is, take that results from, but is not the 
purpose of, carrying out an otherwise lawful activity, will not apply 
to these species; and (4) Collection of these species is prohibited in 
coastal counties south of Interstate 4 and extending to the boundaries 
of the State of Florida at the endpoints of Interstate 4 at Tampa and 
Daytona Beach. Specifically, such activities are prohibited in the 
following counties: Brevard, Broward, Charlotte, Collier, De Soto, 
Hillsborough, Indian River, Lee, Manatee, Pinellas, Sarasota, St. 
Lucie, Martin, Miami-Dade, Monroe, Palm Beach, and Volusia.
    We propose to remove section 4(e) similarity of appearance 
treatment for cassius blue butterfly, ceraunus blue butterfly, and 
nickerbean blue butterfly as threatened species at 50 CFR 17.11 
together with the corresponding 4(e) regulations at 50 CFR 17.47(a). 
According to our most recent status review, the threat of collection of 
Miami blue butterflies has likely been reduced, in part due to the 
remote locations of Miami blue butterfly and reduction in occupied 
areas (Service 2024, p. 5).
    The Miami blue butterfly is listed as a federally designated 
endangered species under Florida law (68A-27.003, Florida 
Administrative Code). Under Florida law, no person shall take, possess, 
or sell endangered species, or parts thereof or their nests or eggs 
except as allowed by specific Federal or State permit or authorization. 
No person shall intentionally kill, attempt to kill or wound any 
species that is both designated in Rule 68A-27.003 of the Florida 
Administrative Code and designated in 50 CFR 17.11 as endangered. This 
proposal would not alter any protections under State or Federal law 
relating to activities with the Miami blue butterfly. Anyone under the 
jurisdiction of the United States that engages in prohibited activities 
with the Miami blue butterfly without a permit is subject to law 
enforcement.
    Cassius blue butterfly, ceraunus blue butterfly, and nickerbean 
blue butterfly are also listed due to similarity of appearance to Miami 
blue butterfly under Florida law (68A-27.003). Under Florida law, 
incidental take, that is, take that results from, but is not a purpose 
of, carrying out an otherwise lawful activity does not apply to cassius 
blue butterfly, ceraunus blue butterfly, and nickerbean blue butterfly. 
Florida law also prohibits collection of the cassius blue butterfly, 
ceraunus blue butterfly, and nickerbean blue butterfly in the coastal 
counties south of Interstate 4 and extending to the boundaries of the 
State of Florida at endpoints of Interstate 4 at Tampa and Daytona 
Beach. Specifically, such activities are prohibited in the following 
counties: Brevard, Broward, Charlotte, Collier, De Soto, Hillsborough, 
Indian River, Lee, Manatee, Pinellas, Sarasota, St. Lucie, Martin, 
Miami-Dade, Monroe, Palm Beach, and Volusia.
    We continue to find that the cassius blue butterfly, ceraunus blue 
butterfly, and nickerbean blue butterfly closely resemble in appearance 
the Miami blue butterfly in the wild. However, there are morphological 
features that can differentiate the species and enforcement personnel 
should not have substantial difficulty in attempting to differentiate 
between collected individuals of the species after

[[Page 46375]]

conferring with species experts. In addition, the effect of this 
substantial difficulty is not an additional threat to the Miami blue 
butterfly as there are no records of ongoing collection of this 
species, likely due to rarity and remote locations. Finally, collection 
of cassius blue butterfly, ceraunus blue butterfly, and nickerbean blue 
butterfly is prohibited by Florida law; however, we recognize that the 
law cites to the protections afforded under the Act and it is unclear 
what kind of protections may continue after our proposed removal of 
such treatment.
    We appreciate and are seeking comments from the State of Florida on 
this proposal. We find that continuing this treatment will not 
substantially facilitate the enforcement and the policy of the Act. 
Therefore, treating the cassius blue butterfly, ceraunus blue 
butterfly, and nickerbean blue butterfly as threatened species is no 
longer advisable in accordance with section 4(e) because not all of the 
three statutory criteria are met.

Pallid Sturgeon and Shovelnose Sturgeon

    On September 6, 1990, the Service listed the pallid sturgeon as an 
endangered species due to curtailment of range, habitat destruction and 
modification, low population size, lack of recruitment, commercial 
harvest, pollution and contaminants, and hybridization (55 FR 36641). 
Another sturgeon species, the shovelnose sturgeon, can be difficult to 
differentiate from the pallid sturgeon in the wild.
    At the time the pallid sturgeon was listed, within areas of overlap 
in the Missouri and Mississippi River basins, Illinois, Kentucky, 
Missouri, and Tennessee, commercial harvest of shovelnose sturgeon was 
allowed. In a 2007 status review, we found that State fishing 
regulations had helped reduce commercial harvest of pallid sturgeon, 
but that incidental and illegal take during commercial harvest of 
shovelnose sturgeon was still having a substantial and detrimental 
effect on the pallid sturgeon (Service 2007, pp. 45-48). Subsequently, 
on September 1, 2010, we finalized a rule under section 4(e) of the Act 
(75 FR 53598) treating the shovelnose sturgeon as a threatened species 
due to its similarity of appearance to the pallid sturgeon to reduce 
the threat of harvest of pallid sturgeon.
    To prevent misidentification with pallid sturgeon where their 
ranges overlap with shovelnose sturgeon, regulations at 50 CFR 
17.44(aa) establish certain prohibitions and exceptions for activities 
with regard to the shovelnose sturgeon, shovelnose-pallid sturgeon 
hybrids, or their roe, and provides that the Service has the authority 
to permit otherwise prohibited actions under 50 CFR 17.32.
    We propose to remove treatment for the shovelnose sturgeon as a 
threatened species at 50 CFR 17.11 together with the corresponding 4(e) 
regulations at 50 CFR 17.44(aa). According to our most recent status 
review, all threats identified at the time of listing, including 
overutilization and overharvest (e.g., due to similarity of appearance 
to the shovelnose sturgeon), remain a concern (Service 2021, p. 4). 
However, the regulations regarding commercial harvest of pallid 
sturgeon, and the potential for misidentification of pallid sturgeon as 
shovelnose sturgeon, are largely duplicative with several State laws.
    For example, in Illinois, shovelnose sturgeon may not be 
commercially harvested except in the Mississippi River upstream of the 
Mel Price Lock and Dam in Alton, Illinois (excluding the area from lock 
and dam 19 to the State Highway 9 bridge in Niota), the Ohio River, and 
the Wabash River. Shovelnose sturgeon may only be commercially 
harvested from October 1 through May 31 from the Mississippi and Wabash 
River and from October 15 through May 15 from the Ohio River. A 
commercial roe harvest permit is required to commercially harvest 
shovelnose sturgeon from any body of water. Illinois also has size 
limits for shovelnose sturgeon from certain rivers (<a href="https://www.ifishillinois.org/programs/commercialfish.html">https://www.ifishillinois.org/programs/commercialfish.html</a>). In Missouri, due 
to the 4(e) regulations of shovelnose sturgeon, the harvest of the 
flesh or roe of shovelnose sturgeon and shovelnose-pallid sturgeon 
hybrids by commercial fishing methods is prohibited in the entire 
Missouri River and in the Mississippi River below Melvin Price Locks 
and Dam near Alton, Illinois (<a href="https://mdc.mo.gov/fishing/regulations/commercial-shovelnose-fishing-restricted">https://mdc.mo.gov/fishing/regulations/commercial-shovelnose-fishing-restricted</a>).
    We recognize that many State laws are based upon the 4(e) 
similarity of appearance listing and it is unclear what kind of 
protections may continue after our proposed removal of such treatment. 
We appreciate and are seeking comments from affected States on this 
proposal. This proposal would not alter any protections under section 
9(a)(1) of the Act for the pallid sturgeon. Anyone under the 
jurisdiction of the United States that engages in prohibited activities 
with the pallid sturgeon without a permit is subject to law 
enforcement.
    We continue to find that the shovelnose sturgeon and shovelnose-
pallid sturgeon hybrids, or their roe, closely resemble in appearance 
the pallid sturgeon in the wild. However, given the genetic 
differentiation of the species, enforcement personnel should not have 
substantial difficulty in attempting to differentiate between collected 
individuals, though distinction between roe of the species may continue 
to prove substantially difficult. While the effect of this substantial 
difficulty is an additional threat to the pallid sturgeon, we find that 
this treatment will not substantially facilitate the enforcement and 
the policy of the Act. Therefore, treating the shovelnose sturgeon as a 
threatened species is no longer advisable in accordance with section 
4(e) because not all of the three statutory criteria are met.

Bog Turtle (Northern DPS) and Bog Turtle (Southern DPS)

    On November 4, 1997, the Service published a final rule (62 FR 
59605) listing the northern DPS of the bog turtle as a threatened 
species due to a variety of factors including habitat degradation and 
fragmentation from agriculture and development, habitat succession due 
to invasive exotic and native plants, and illegal trade and collecting. 
We determined that collection was a significant factor in the species 
decline and a threat to its continued existence in the wild. Difficulty 
in differentiating morphology and identifying source populations of 
individuals poses a problem for Federal and State law enforcement 
agents working to stop illegal trade in the northern population. 
Therefore, in that final rule, we also made final determinations to 
treat the southern DPS of the bog turtle as a threatened species and 
issued regulations at 50 CFR 17.42(f) outlining the prohibitions and 
exceptions for the southern DPS.
    The treatment of the southern population as a threatened species 
due to similarity of appearance was intended to eliminate the ability 
of commercial collectors to commingle northern bog turtles with 
southern ones or to misrepresent them as southern bog turtles for 
commercial purposes (62 FR 59605 at 59622, November 4, 1997). According 
to our most recent status review, collection and trade of bog turtles 
is a continued threat with an investigation as recently as August 2018, 
and we are aware of continued interest in illegally obtaining bog 
turtles (Service 2022, p. 11).
    The regulations at 50 CFR 17.42(f) establish certain prohibitions 
and

[[Page 46376]]

exceptions for activities with regard to the southern DPS of bog 
turtle. Specifically, the regulations include all of the section 
9(a)(1) prohibitions with regard to the southern DPS. Incidental take, 
that is, take that results from, but is not the purpose of, carrying 
out an otherwise lawful activity, does not apply to the southern DPS. 
The regulations also provide several exceptions to these prohibitions. 
For example, Federal and State law enforcement officers may possess, 
deliver, carry, transport, or ship the southern DPS taken in violation 
of the Act as necessary in performing their official duties; certain 
individuals can take individuals to aid, salvage, or dispose of the 
southern DPS; States, the Service, and National Marine Fisheries 
Service (NMFS) can take individuals when carrying out conservation 
programs; and the Service has the authority to permit otherwise 
prohibited actions under 50 CFR 17.32.
    We propose to amend the treatment of the southern DPS of bog turtle 
as a threatened species by revising the regulations at 50 CFR 
17.42(f)(2) to authorize activities that are otherwise prohibited under 
a similarity of appearance permit (50 CFR 17.52) instead of a permit at 
50 CFR 17.32. The regulations at 50 CFR 17.52 pertain to permits for 
similarity of appearance cases and outline application requirements, 
issuance criteria, permit conditions, and duration of permits. The 
regulations at 50 CFR 17.32 pertain to permits for threatened species 
(i.e., those listed as threatened under section 4(a) of the Act).
    Issuance criteria for permits for similarity of appearance species 
at 50 CFR 17.52 are minimal compared to those for species listed under 
section 4(a) and are as follows: (1) Whether the information submitted 
by the applicant appears reliable, and (2) whether the information 
submitted by the applicant adequately identifies the wildlife or plant 
in question so as to distinguish it from any endangered or threatened 
wildlife or plant. The 50 CFR 17.52 criteria for obtaining permits are 
focused on whether the applicant has provided reliable evidence that 
the specimen subject to the otherwise prohibited activity is from an 
unlisted similarity of appearance species under section 4(e) or is from 
a listed species under section 4(a).
    The issuance criteria at 50 CFR 17.32(a)(2) for threatened species 
are more detailed and focus on the conservation needs of the species. 
The issuance criteria under 50 CFR 17.32(a)(2) considers the following 
factors: (1) Whether the purpose for which the permit is required is 
adequate to justify removing from the wild or otherwise changing the 
status of the wildlife sought to be covered by the permit; (2) The 
probable direct and indirect effect which issuing the permit would have 
on the wild populations of the wildlife sought to be covered by the 
permit; (3) Whether the permit, if issued, would in any way, directly 
or indirectly, conflict with any known program intended to enhance the 
survival probabilities of the population from which the wildlife sought 
to be covered by the permit was or would be removed; (4) Whether the 
purpose for which the permit is required would be likely to reduce the 
threat of extinction facing the species of wildlife sought to be 
covered by the permit; (5) The opinions or views of scientists or other 
persons or organizations having expertise concerning the wildlife or 
other matters germane to the application; and (6) Whether the 
expertise, facilities, or other resources available to the applicant 
appear adequate to successfully accomplish the objectives stated in the 
application.
    It is generally more appropriate to regulate species that are not 
at risk of extinction but are treated as a listed species to conserve 
another species under our permitting regulations at 50 CFR 17.52 rather 
than 50 CFR 17.32 to ensure they are accurately identified prior to 
authorizing otherwise prohibited activity. We find that it would be 
appropriate to ensure the continued identification of the unlisted 
southern DPS of bog turtle as distinct from the listed northern DPS 
when authorizing otherwise prohibited activities. We anticipate persons 
involved in legal activities with the southern DPS would have access to 
the necessary information and have minimal difficulty meeting their 
burden to produce evidence that the specimen is from the southern DPS. 
The bog turtle is listed as threatened or endangered in every State in 
the southern and northern portion of the range and State-issued permits 
may also be needed for activities with the southern DPS.
    We also propose to revise the wording at 50 CFR 17.42(f)(2) to make 
the current prohibitions and exceptions clearer. We currently cite to 
50 CFR 17.31(a) and (b), which then cites to the applicable 
prohibitions and exceptions. Instead, we propose to cite directly to 
the applicable prohibitions and exceptions, as this is clearer for the 
public and is more in keeping with the current practice for species-
specific rules. These minor clarifications would result in no change in 
prohibitions or exceptions.
    This proposal would not alter any protections for the northern DPS 
of the bog turtle. Anyone under the jurisdiction of the United States 
that engages in prohibited activities with either the northern or 
southern DPS without a permit are subject to law enforcement. 
Additionally, this proposal would not affect any threatened species 
permits currently issued under the authority of 50 CFR 17.32 for the 
similarity of appearance species; any such permits issued under the 
stricter standards would continue to be valid in accordance with their 
terms and conditions.
    We continue to find that the southern DPS of the bog turtle so 
closely resembles the northern DPS in appearance that enforcement 
personnel would have substantial difficulty in attempting to 
differentiate between the species, and the effect of this substantial 
difficulty is an additional threat to the northern DPS. We also find 
that this proposed revised treatment would continue to substantially 
facilitate the enforcement and the policy of the Act with a lower 
burden to the regulated public and is advisable in accordance with 
section 4(e).

Desert Tortoise (Mojave DPS) and Desert Tortoise (Sonoran DPS)

    On April 2, 1990, the Service published a final rule (55 FR 12178) 
listing the Mojave DPS of desert tortoise as a threatened species due 
to habitat loss and degradation, illegal collection, disease, and 
predation. We also determined that treating the Sonoran DPS of desert 
tortoise as a threatened species due to similarity of appearance to the 
Mojave DPS would facilitate law enforcement (55 FR 12178 at 12189, 
April 2, 1990). Therefore, in that final rule, we also made final 
determinations to treat the Sonoran DPS (desert tortoise found outside 
of Arizona (south and east of the Colorado River) and Mexico) as a 
threatened species and issued regulations at 50 CFR 17.42(e) outlining 
the prohibitions and exceptions for the Sonoran DPS. We subsequently 
identified a threat to desert tortoises from their collection for human 
food sources (Service 1994, p. 6). In our status reviews (Service 2010, 
p. 48; Service 2022, p. 22), we explain that collection still occurs 
and could possibly impact local populations.
    The regulations at 50 CFR 17.42(e) establish certain prohibitions 
and exceptions for activities with regard to the Sonoran DPS of desert 
tortoise. Specifically, the regulations make it illegal for any person 
subject to the jurisdiction of the United States to commit, to attempt 
to commit, to solicit

[[Page 46377]]

another to commit, or to cause to be committed any of the following 
acts with regard to the Sonoran DPS: (1) import into, or export from, 
the United States; (2) take (which includes harass, harm, pursue, hunt, 
shoot, wound, kill, trap, capture, or collect, or to attempt to engage 
in any such conduct) within the United States, within the territorial 
sea of the United States, or on the high seas; (3) possess, sell, 
deliver, carry, transport, or ship, by any means whatsoever, any such 
wildlife that has been taken illegally; (4) deliver, receive, carry, 
transport, or ship in interstate or foreign commerce, by any means 
whatsoever and in the course of commercial activity; or (5) sell or 
offer for sale in interstate or foreign commerce.
    The regulations also provide several exceptions to these 
prohibitions (e.g., Federal and State law enforcement officers may 
possess, deliver, carry, transport, or ship the Sonoran DPS taken in 
violation of the Act as necessary in performing their official duties; 
certain individuals can take individuals to aid, salvage, or dispose of 
the Sonoran DPS; States, the Service and NMFS can take individuals when 
carrying out conservation programs; and the Service has the authority 
to permit otherwise prohibited actions under 50 CFR 17.32).
    We propose to amend the treatment of the Sonoran DPS of desert 
tortoise as a threatened species by revising the regulations at 50 CFR 
17.42(e) to authorize activities that are otherwise prohibited under a 
similarity of appearance permit (50 CFR 17.52) instead of a permit at 
50 CFR 17.32 for the same rationale as provided for the bog turtle 
above. It is generally more appropriate to regulate species that are 
not at risk of extinction but are treated as a listed species to 
conserve another species, under our permitting regulations at 50 CFR 
17.52 rather than 50 CFR 17.32, to ensure they are accurately 
identified prior to authorizing otherwise prohibited activity.
    We find that it would be appropriate to ensure the continued 
identification of the unlisted Sonoran DPS as distinct from the listed 
Mojave DPS when authorizing otherwise prohibited activities. We 
anticipate persons involved in legal activities with desert tortoises 
from the Sonoran DPS would have access to the necessary information and 
have minimal difficulty meeting their burden to produce evidence that 
the specimen is from the Sonoran DPS.
    We also propose to revise the wording at 50 CFR 17.42(e)(2) to make 
the current prohibitions and exceptions clearer. We currently cite to 
50 CFR 17.31-17.32, which then cite to the applicable prohibitions and 
exceptions. Instead, we propose to cite directly to the applicable 
prohibitions and exceptions, as this is clearer for the public and is 
more in keeping with the current practice for species-specific rules. 
These minor clarifications would result in no change in prohibitions or 
exceptions.
    This proposal would not alter any protections for the Mojave DPS of 
desert tortoise. Anyone under the jurisdiction of the United States 
that engages in prohibited activities with either the Mojave or Sonoran 
DPS without a permit is subject to law enforcement. Additionally, this 
proposal would not affect any threatened species permits currently 
issued under the authority of 50 CFR 17.32 for the similarity of 
appearance species; any such permits issued under the stricter 
standards would continue to be valid in accordance with their terms and 
conditions.
    We continue to find that the Sonoran DPS of desert tortoise so 
closely resembles in appearance the Mojave DPS that enforcement 
personnel would have substantial difficulty in attempting to 
differentiate between the species, and the effect of this substantial 
difficulty is an additional threat to the Mojave DPS. We also find that 
this proposed revised treatment would continue to substantially 
facilitate the enforcement and the policy of the Act with a lower 
burden to the regulated public and is advisable in accordance with 
section 4(e).

Pearl River Map Turtle and Alabama Map Turtle, Barbour's Map Turtle, 
Escambia Map Turtle, and Pascagoula Map Turtle

    On July 12, 2024, the Service published a final rule (89 FR 57206) 
listing the Pearl River map turtle as a threatened species. In that 
final rule, we also made final determinations to treat the Alabama map 
turtle, Barbour's map turtle, Escambia map turtle, and Pascagoula map 
turtles as threatened species and issued regulations at 50 CFR 17.42(n) 
outlining the prohibitions and exceptions for those species. We 
determined that the Alabama map turtle, Barbour's map turtle, Escambia 
map turtle, and Pascagoula map turtle all closely resemble in 
appearance the Pearl River map turtle such that enforcement personnel 
would have substantial difficulty in attempting to differentiate 
between the species. We also determined that treating these species as 
listed species minimizes the possibility that private and commercial 
collectors will be able to misrepresent Pearl River map turtles as 
Alabama map turtles, Barbour's map turtles, Escambia map turtles, or 
Pascagoula map turtles for private or commercial purposes (89 FR 57206 
at 57232, July 12, 2024).
    The regulations at 50 CFR 17.42(n) establish certain prohibitions 
and exceptions for activities with regard to the Alabama map turtle, 
Barbour's map turtle, Escambia map turtle, or Pascagoula map turtle. 
Specifically, the regulations make it illegal for any person subject to 
the jurisdiction of the United States to commit, to attempt to commit, 
to solicit another to commit, or to cause to be committed any of the 
following acts with regard to the Alabama map turtle, Barbour's map 
turtle, Escambia map turtle, and Pascagoula map turtle: (1) import 
into, or export from, the United States; (2) intentional take in the 
form of collect, capture, or trap (other than for scientific purposes); 
(3) possess, sell, deliver, carry, transport, or ship, by any means 
whatsoever, any such wildlife that has been taken illegally; (4) 
deliver, receive, carry, transport, or ship in interstate or foreign 
commerce, by any means whatsoever and in the course of commercial 
activity; or (5) sell or offer for sale in interstate or foreign 
commerce.
    The regulations also provide several exceptions to these 
prohibitions. For example, Federal and State law enforcement officers 
may possess, deliver, carry, transport, or ship the Alabama map turtle, 
Barbour's map turtle, Escambia map turtle, and Pascagoula map turtle 
taken in violation of the Act as necessary in performing their official 
duties; certain individuals can take individuals to aid, salvage, or 
dispose of the Alabama map turtle, Barbour's map turtle, Escambia map 
turtle, and Pascagoula map turtle; and the States, Service, and NMFS 
can take individuals when carrying out conservation programs; and the 
Service has the authority to permit otherwise prohibited actions under 
50 CFR 17.32.
    We propose to amend the treatment of the Alabama map turtle, 
Barbour's map turtle, Escambia map turtle, and Pascagoula map turtle as 
threatened species by revising the regulations at 50 CFR 17.42(n) to 
authorize activities that are otherwise prohibited under a similarity 
of appearance permit at 50 CFR 17.52 instead of a permit at 50 CFR 
17.32.
    It is generally more appropriate to regulate species that are not 
at risk of extinction but are treated as a listed species to conserve 
another species, under our permitting regulations at 50 CFR 17.52 
rather than 50 CFR 17.32, to

[[Page 46378]]

ensure they are accurately identified prior to authorizing otherwise 
prohibited activity. We find that it would be appropriate to ensure the 
continued identification of these unlisted species as distinct from the 
Pearl River map turtle when authorizing otherwise prohibited 
activities. We anticipate persons involved in legal activities with 
these species would have access to the necessary information and have 
minimal difficulty meeting their burden to produce evidence of 
identification to the species level.
    This proposal would not alter any protections for the Pearl River 
map turtle. Anyone under the jurisdiction of the United States that 
engages in prohibited activities with the Pearl River map turtle or the 
Alabama map turtle, Barbour's map turtle, Escambia map turtle, and 
Pascagoula map turtle without a permit are subject to law enforcement. 
Additionally, this proposal would not affect any threatened species 
permits currently issued under the authority of 50 CFR 17.32 for the 
similarity of appearance species; any such permits issued under the 
stricter standards would continue to be valid in accordance with their 
terms and conditions.
    We continue to find that the Alabama map turtle, Barbour's map 
turtle, Escambia map turtle, and Pascagoula map turtle so closely 
resembles in appearance the Pearl River map turtle that enforcement 
personnel would have substantial difficulty in attempting to 
differentiate between the species and the effect of this substantial 
difficulty is an additional threat to the Pearl River map turtle. We 
also find that this proposed revised treatment would continue to 
substantially facilitate the enforcement and the policy of the Act with 
a lower burden to the regulated public and is advisable in accordance 
with section 4(e).

Required Determinations

Regulatory Planning and Review--E.O.s 12866 and 13563

    E.O. 12866 provides that the Office of Information and Regulatory 
Affairs (OIRA) in the Office of Management and Budget will review all 
significant rules. OIRA has determined that this proposed rule is not 
significant.
    E.O. 13563 reaffirms the principles of E.O. 12866 while calling for 
improvements in the Nation's regulatory system to promote 
predictability, to reduce uncertainty, and to use the best, most 
innovative, and least burdensome tools for achieving regulatory ends. 
E.O. 13563 directs agencies to consider regulatory approaches that 
reduce burdens and maintain flexibility and freedom of choice for the 
public where these approaches are relevant, feasible, and consistent 
with regulatory objectives. E.O. 13563 emphasizes further that 
regulations must be based on the best available science and that the 
rulemaking process must allow for public participation and an open 
exchange of ideas. We have developed this proposed rule in a manner 
consistent with these requirements.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.), 
as amended by the Small Business Regulatory Enforcement Fairness Act of 
1996 (SBREFA; title II of Pub. L. 104-121, March 29, 1996), whenever a 
Federal agency is required to publish a notice of rulemaking for any 
proposed or final rule, it must prepare, and make available for public 
comment, a regulatory flexibility analysis that describes the effect of 
the rule on small entities (i.e., small businesses, small 
organizations, and small government jurisdictions). However, no 
regulatory flexibility analysis is required if the head of an agency, 
or that person's designee, certifies that the rule will not have a 
significant economic impact on a substantial number of small entities. 
SBREFA amended the RFA to require Federal agencies to provide a 
statement of the factual basis for certifying that a rule will not have 
a significant economic impact on a substantial number of small 
entities.
    This rulemaking proposes to remove or revise the Service's 
regulations treating 11 species as threatened species under section 
4(e) of the Act based on similarity of appearance to listed species. 
Removing treatment under section 4(e) or revising 4(e) regulations to 
require permitting under 50 CFR 17.52 instead of 17.32 would reduce 
regulatory burden. We certify that, if adopted as proposed, this rule 
would not have a significant economic effect on a substantial number of 
small entities.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
et seq.):
    (a) On the basis of information contained above in the Regulatory 
Flexibility Act section, this proposed rule would not ``significantly 
or uniquely'' affect small governments. We have determined and certify 
pursuant to the Unfunded Mandates Reform Act that this proposed rule 
would not impose a cost of $100 million or more in any given year on 
local or State governments or private entities. A small government 
agency plan is not required. As explained above, small governments 
would not be affected because the proposed rule would not place 
additional requirements on any city, county, or other local 
municipalities.
    (b) This proposed rule would not produce a Federal mandate on 
State, local, or Tribal governments or the private sector of $100 
million or greater in any year; that is, this proposed rule is not a 
``significant regulatory action'' under the Unfunded Mandates Reform 
Act. This proposed rule would impose no obligations on State, local, or 
Tribal governments.

Takings --E.O. 12630

    In accordance with E.O. 12630 (``Governmental Actions and 
Interference with Constitutionally Protected Property Rights''), this 
proposed rule would not have significant takings implications. This 
proposed rule would not pertain to ``taking'' of private property 
interests, nor would it directly affect private property. A takings 
implication assessment is not required because this proposed rule (1) 
would not effectively compel a property owner to suffer a physical 
invasion of property and (2) would not deny all economically beneficial 
or productive use of the land or aquatic resources. This proposed rule 
would substantially advance a legitimate government interest 
(conservation and recovery of endangered species and threatened 
species) and would not present a barrier to all reasonable and expected 
beneficial use of private property.

Federalism--E.O. 13132

    In accordance with E.O. 13132 (``Federalism''), this proposed rule 
would not have significant federalism effects. This proposed rule would 
not have substantial direct effects on the States, on the relationship 
between the States and the Federal Government, or on the distribution 
of power and responsibilities among the various levels of government.

Civil Justice Reform--E.O. 12988

    This proposed rule would not unduly burden the judicial system and 
meets the applicable standards provided in sections 3(a) and 3(b)(2) of 
E.O. 12988 (``Civil Justice Reform'').

Government-to-Government Relationship With Tribes

    In accordance with E.O.13175, (``Consultation and Coordination With

[[Page 46379]]

Indian Tribal Governments''), and the Department of the Interior's 
manual at 512 DM 2, we are considering possible effects of this 
proposed rule on federally recognized Indian Tribes. The Service has 
reached a preliminary conclusion that the proposed rule would not 
directly affect any specific Tribal lands, treaty rights, or Tribal 
trust resources. This proposed rule would revise regulations for 
several species pursuant to section 4(e) of the Act. These proposed 
regulations would not have substantial direct effects on one or more 
Indian Tribes, on the relationship between the Federal Government and 
Indian Tribes, or on the distribution of power and responsibilities 
between the Federal Government and Indian Tribes.
    We are considering the possible effects of this proposed rule on 
federally recognized Indian Tribes. We will continue to collaborate 
with Tribes on issues related to federally listed species and their 
habitats and work with them as we implement the provisions of the Act. 
See Secretary's Order 3206, ``American Indian Tribal Rights, Federal-
Tribal Trust Responsibilities, and the Endangered Species Act'' (June 
5, 1997).

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This proposed rule does not contain any new collection of 
information that requires approval by the OMB under the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.). An agency may not 
conduct or sponsor, and a person is not required to respond to, a 
collection of information unless it displays a currently valid OMB 
control number.

National Environmental Policy Act (NEPA) (42 U.S.C. 4321 et seq.)

    We are analyzing this proposed rule in accordance with the criteria 
of the NEPA (42 U.S.C. 4321 et seq.), the Department of the Interior 
regulations on Implementation of the National Environmental Policy Act 
(43 CFR 46), and the Department of the Interior Manual (516 DM 8). We 
invite the public to comment on the extent to which these proposed 
regulation revisions may have a significant impact on the human 
environment or fall within one of the categorical exclusions for 
actions that have no reasonably foreseeable effects on the quality of 
the human environment. We will complete our analysis, in compliance 
with NEPA, before finalizing these proposed regulation revisions.

Energy Supply, Distribution or Use--E.O. 13211

    E.O. 13211 requires agencies to prepare statements of energy 
effects when undertaking certain actions. The proposed revised 
regulations are not expected to affect energy supplies, distribution, 
and use. Therefore, this action is not a significant energy action, and 
no statement of energy effects is required.

Clarity of the Proposed Rule

    We are required by E.O.s 12866 and 12988 and by the Presidential 
memorandum of June 1, 1998, to write all rules in plain language. This 
means that each rule we publish must:
    (1) Be logically organized;
    (2) Use the active voice to address readers directly;
    (3) Use clear language rather than jargon;
    (4) Be divided into short sections and sentences; and
    (5) Use lists and tables wherever possible.
    If you believe that we have not met these requirements, send us 
comments by one of the methods listed in ADDRESSES. To better help us 
revise the rule, your comments should be as specific as possible. For 
example, you should tell us the numbers of the sections or paragraphs 
that are unclearly written, which sections or sentences are too long, 
the sections where you feel lists or tables would be useful, etc.
