Rescinding the Definition of ``Harm'' Under the Endangered 
Species Act

AGENCY: U.S. Fish and Wildlife Service, Interior; National Oceanic and 
Atmospheric Administration, Commerce.

ACTION: Final rule.

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

SUMMARY: We, the U.S. Fish and Wildlife Service (FWS) and the National 
Marine Fisheries Service (NMFS; collectively referred to as the 
``Services'') rescind the regulatory definition of ``harm'' in our 
Endangered Species Act (ESA or the Act) regulations. This rescission 
removes the regulatory definition of ``harm'' from the Code of Federal 
Regulations (CFR) in Title 50 parts 17 and 222.

DATES: This final rule is effective September 14, 2026.

ADDRESSES: Public comments and materials received, as well as 
supporting documentation used in the preparation of this final rule, 
are available online at https://www.regulations.gov in Docket No. FWS-
HQ-ES-2025-0034.

SUPPLEMENTARY INFORMATION:

Background

    The Endangered Species Act, as amended, (hereafter referred to as 
ESA or the Act; 16 U.S.C. 1531 et seq.) prohibits the ``take'' of 
endangered wildlife under section 9 (16 U.S.C. 1538). This is part of a 
detailed statutory scheme that lays different responsibilities, powers, 
and prohibitions on the federal government and private citizens, as 
part of an overall effort to protect endangered species. Section 7 of 
the ESA imposes on the federal government the responsibility to 
``insure that any action authorized, funded, or carried out by such 
agency . . . is not likely to jeopardize the continued existence of any 
endangered species or threatened species or result in the destruction 
or adverse modification of habitat which is determined by the Secretary 
. . . to be critical . . . .'' (16 U.S.C. 1536(a)(2)). Section 5 
empowers the federal government to purchase private property ``to 
conserve fish, wildlife, and plants, including those which are listed 
as endangered species or threatened species'' (16 U.S.C. 1534). And 
section 9 prohibits private citizens from ``tak[ing]'' animals that are 
members of an endangered species (16 U.S.C. 1538).
    ``Take'' is a term with a traditional meaning, i.e., to kill or 
capture a wild animal. See Oxford English Dictionary (1933; third 
printing in February 1973). The Act provides its own definition in 
section 3, which expands that meaning slightly: ``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). This 
definition ``make[s] clear'' that ``take,'' as used in the statute, 
``include[s] not just a completed taking, but the process of taking, 
and all of the acts that are customarily identified with or accompany 
that process . . . so as to include attempts'' (Babbitt v. Sweet Home 
Chapter of Communities for a Great Oregon, 515 U.S. 687, 718 (1995) 
(Scalia, J., dissenting)). This is a slight, sensible, and ``not 
unusual[]'' expansion of the traditional definition of ``take''; even 
so, the traditional meaning of ``take'' remains plainly the core of 
what is being defined (Id.).
    Thus, under the statutory scheme as enacted, the government would 
``insure'' that its own actions did not ``jeopardize the continued 
existence of any endangered species or threatened species'' or ``result 
in the destruction or adverse modification of'' critical habitat (a 
statutory term that is different from the habitat, simpliciter, of the 
species). Meanwhile, where government action is not involved, the Act 
protects endangered species in two ways: by directly prohibiting 
citizens from killing, injuring, or capturing any member of those 
species (or attempting to do so), and by purchasing the land of private 
citizens to assist in conservation. To complete this regime, Section 10 
then creates an incidental-take regime for when such take is 
nonetheless inevitable in the pursuit of some other activity, as when 
fishing for a non-endangered species of fish will, inadvertently but 
inevitably, lead to the catch of an endangered species of fish.
    But starting in 1975, FWS promulgated regulatory definitions of 
``harm'' that dramatically expanded the plain meaning of ``take,'' to 
sweep in (and thus prohibit) actions that impair the habitat of 
protected species. That year, FWS published a final rule that defined 
``harm'' as ``...an act or omission which actually injures or kills 
wildlife, including acts which annoy it to such an extent as to 
significantly disrupt essential behavioral patterns, which include, but 
are not limited to, breeding, feeding or sheltering; significant 
environmental modification or degradation which has such effects is 
included within the meaning of `harm' (40 FR 44412 at 44416, Sept. 26, 
1975) (emphasis added)).\1\ Indeed, the history of this regulation 
suggests that FWS's original goal was not to define ``harm,'' but to 
prohibit habitat modification by private citizens, irrespective of 
means: When the Service first proposed the regulation, it incorporated 
a prohibition on habitat modification as part of the definition of a 
completely different word, ``harass'' (see 40 FR 28712). Only at the 
final-rule stage did FWS shift this prohibition into the definition of 
``harm,'' with little to no explanation of why (see 40 FR 44413).\2\
---------------------------------------------------------------------------

    \1\ It is indicative that the end in mind was prohibiting 
habitat modification by private citizens, rather than construing the 
meaning of ``harm,'' that the Service initially proposed this rule 
in a form that would have made a prohibition on habitat modification 
a part of the definition of a completely different word, ``harass.'' 
See 40 FR 28712.
    \2\ What little explanation the final rule provided for this 
change suggests that FWS was by that time focused on principles of 
intent and causation. The rule noted that FWS was modifying the 
definition of ``harass'' and that ``[t]he concept of environmental 
damage being considered a `taking' has been retained, but is now 
found in a new definition, of the word `harm''' (Id.). It then went 
on state that ```[h]arm covers actions or omissions which actually, 
(as opposed to potentially), cause injury,'' and that, ``[i]n 
addition, the definition of `harass' has been modified by 
restricting its application to acts or omissions which are done 
intentionally or negligently. In the proposal, `harass' would have 
applied to any action, regardless of intent or negligence'' (Id.). 
None of this explains why the Services suddenly had concluded that 
habitat modification was an intrinsic part of the word ``harm,'' or 
why it was no longer part of the word ``harass.''
---------------------------------------------------------------------------

    In 1981, FWS drew back slightly, redefining ``harm'' in 1981 to 
``an act which actually kills or injures wildlife. Such act may include 
significant habitat modification or degradation where it actually kills 
or injures wildlife by significantly impairing essential

[[Page 43301]]

behavioral patterns, including breeding, feeding or sheltering'' (46 FR 
54748 at 54750, Nov. 4, 1981). FWS explained its modification on the 
grounds that the previous definition could have been construed as 
prohibiting habitat modification even where there was no injury to the 
listed endangered or threatened wildlife, which would ``go beyond the 
intent of Congress'' (46 FR 54748, November 4, 1981). Nonetheless, the 
fundamental shift had already occurred, and the 1981 rulemaking did not 
undo it: FWS has transformed section 9 by the issuance of regulatory 
definitions from a prohibition on private citizens hunting, capturing, 
or otherwise attempting to kill or injure certain specifically 
protected animals into a sweeping land-use regulation. Against that 
backdrop, section 10's ``incidental take'' regime became a land-use 
regime.
    NMFS did not define ``harm'' in regulations until 1999 (see 64 FR 
60731,Nov. 8, 1999). When it did so, it adopted a definition similar to 
FWS's 1981 redefinition but included NMFS-specific modifiers: ``an act 
which actually kills or injures fish or wildlife. Such an act may 
include significant habitat modification or degradation which actually 
kills or injures fish or wildlife by significantly impairing essential 
behavioral patterns, including, breeding, spawning, rearing, migrating, 
feeding or sheltering'' (Id.).
    In Babbitt v. Sweet Home Chapter of Communities for a Great Oregon, 
515 U.S. 687 (1995; Sweet Home), the Supreme Court rejected a challenge 
to FWS's regulation by applying Chevron deference and determining that 
FWS's interpretation of the ESA was a ``reasonable''--even if not the 
best--interpretation of the statute \3\ (Id. at 697, 703). In a dissent 
that has literally become textbook,\4\ Justice Scalia, joined by then-
Chief Justice Rehnquist and Justice Thomas, explained why FWS's 
construction was not the best reading of the statute; indeed, Justice 
Scalia would have held that FWS's interpretation of ``harm'' was not 
even a permissible reading of the statute under Chevron, given its 
inconsistency with the structure and text of the ESA. As Justice Scalia 
observed, ``[i]f `take' were not elsewhere defined in the Act, none 
could dispute what it means, for the term is as old as the law itself. 
To `take,' when applied to wild animals, means to reduce those animals, 
by killing or capturing, to human control'' (515 U.S. at 717 (Scalia, 
J., dissenting)).\5\ And here, under the noscitur a sociis canon, the 
term ``harm,'' like the other nine verbs in the definition of ``take,'' 
should be construed to require an ``affirmative act[] . . . directed 
immediately and intentionally against a particular animal--not [an] 
act[] or omission[] that indirectly and accidentally cause[s] injury to 
a population of animals (515 U.S. at 719-720 (Scalia, J., dissenting); 
see also id. at 719 (```Harm' is merely one of 10 prohibitory words in 
[the ESA's definition of ``take''], and the other 9 fit the ordinary 
meaning of `take' perfectly.'')).
---------------------------------------------------------------------------

    \3\ The Services are aware that at least one intermediate court 
has suggested that Sweet Home did not ground its ruling in Chevron 
deference. See Cargill v. Garland, 57 F.4th 447, 467 (5th Cir. 
2023), aff'd sub nom. Garland v. Cargill, 602 U.S. 406 (2024). But 
cf. Lubow v. U.S. Dep't of State, 783 F.3d 877, 884 (D.C. Cir. 2015) 
(citing Babbitt for the proposition that a court can proceed 
directly to Chevron Step Two without a threshold determination of 
ambiguity). The Services do not agree that Sweet Home was not a 
Chevron case. The Court in Sweet Home explained explicitly that it 
``need not decide whether the statutory definition of `take' compels 
the Secretary's interpretation of `harm,' because [the Court's] 
conclusions that Congress did not unambiguously manifest its intent 
to adopt respondents' view and that the Secretary's interpretation 
is reasonable suffice[d] to decide th[e] case'' (515 U.S. 687, 703 
(1995) (citing Chevron U.S.A. Inc. v. Natural Resources Defense 
Council, Inc., 467 U.S. 837 (1984))). The Court described its 
``conclusion that the Secretary's definition of `harm''' as 
``rest[ing] on a permissible construction of the ESA'' (515 U.S. at 
704 (emphasis added); see also id. at 708 (``When Congress has 
entrusted the Secretary with broad discretion, we are especially 
reluctant to substitute our views of wise policy for his. See 
Chevron, 467 U.S. at 865-66. In this case, that reluctance accords 
with our conclusion, based on the text, structure, and legislative 
history of the ESA, that the Secretary reasonably construed the 
intent of Congress when he defined `harm' to include `significant 
habitat modification or degradation that actually kills or injures 
wildlife.''')).
    Furthermore, the Sweet Home Court explicitly refrained from 
``decid[ing] whether the statutory definition of `take' compels the 
Secretary's interpretation of `harm''' (Id. at 703). Thus, 
regardless of the doctrinal reasoning underlying that conclusion, 
Sweet Home does not bear the preclusive effect that some would 
ascribe to it.
    \4\ See, e.g., Mikva, et al., Legislative Process 749 (5th ed. 
2025); Manning & Stephenson, Legislation and Regulation, Cases and 
Materials 1201 (5th ed. 2025).
    \5\ See, e.g., 11 Oxford English Dictionary (1933) (defining 
``take'' as to kill or capture a wild animal); Webster's New 
International Dictionary of the English Language (2d ed. 1949) (take 
defined as ``to catch or capture by trapping, snaring, etc., or as 
prey''); Geer v. Connecticut, 161 U.S. 519, 523 (1896) (``All the 
animals which can be taken upon the earth, in the sea, or in the 
air, that is to say, wild animals, belong to those who take them'') 
(quoting the Digest of Justinian); 2 W. Blackstone, Commentaries 411 
(1766) (``Every man . . . has an equal right of pursuing and taking 
to his own use all such creatures as are ferae naturae'').
---------------------------------------------------------------------------

    Justice Scalia also explained that FWS's definition of ``harm'' 
does not fit with the use of ``take'' throughout the Act, including 
where provisions like section 1538(a)(1)(D) which prohibits the 
possession, sale, and transport of ``species taken in violation'' of 
the Act ``would apply to taking only in the ordinary sense, and are 
meaningless as applied to species injured by environmental 
modification'' (Id. at 723). Nor does FWS's definition of ``harm'' work 
with the ``broader structure of the Act,'' noting that ``Congress's 
explicit prohibition of habitat modification in the [Section 7 of the 
ESA] would bar the inference of an implicit prohibition of habitat 
modification in [Section 9 of the ESA]'' (Id. at 724; see also id. 
(stating that statutes should be read as far as possible to give 
independent effect to all their provisions)).\6\
---------------------------------------------------------------------------

    \6\ Although Sweet Home was focused on FWS's regulation at 50 
CFR 17.3, NMFS's definition of ``harm'' at 50 CFR 222.102 is 
substantially the same.
---------------------------------------------------------------------------

    The Supreme Court recently abrogated the doctrine of Chevron 
deference in Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024) 
(After Loper Bright), ``the question that matters'' in regulatory 
litigation is whether ``the statute authorizes the challenged agency 
action'' (603 U.S. at 406 (emphasis added)). In other words, does the 
agency's regulation match the single, best meaning of the statute?
    We have concluded that the Services' existing regulations, which 
contain the definition of ``harm'' contested in Sweet Home, do not 
match the single, best meaning of the statute. As Justice Scalia's 
dissent in Sweet Home explains, the regulations' interpretation of the 
statutory language runs afoul of the noscitur a sociis canon and is 
inconsistent with the structure of the ESA. We adopt Justice Scalia's 
rationale as articulated in Sweet Home and conclude that the Services' 
regulatory definitions are unlawful, notwithstanding the Court's prior 
upholding of the regulatory definition under Chevron deference.
    We recognize that the Supreme Court held in Loper Bright that its 
``prior cases that relied on the Chevron framework . . . are still 
subject to statutory stare decisis'' (603 U.S. at 412). But under the 
then-prevailing Chevron framework, Sweet Home held only that the 
existing regulation is a permissible reading of the ESA, not the only 
possible such reading. Indeed, even during the Chevron era, the 
Services would have been free to change their interpretation of the 
Act, even after a court had applied Chevron deference to uphold that 
earlier interpretation, as in Sweet Home. See generally Nat'l Cable & 
Telecomms. Ass'n v. Brand X internet Servs., 545 U.S. 967 (2005); see 
also Sweet Home, 515 U.S. at 714 (O'Connor, J., concurring) 
(``[N]othing the Court says today prevents the agency itself from 
narrowing the scope of its

[[Page 43302]]

regulation at a later date.''). That was because a Chevron deference-
grounded precedent did not hold that an agency's ``construction 
follow[ed] from the unambiguous terms of the statute and thus l[eft] no 
room for agency discretion''; rather, such a precedent only established 
that the agency's construction was only one of potentially multiple 
permissible interpretations of the statute (Brand X, 545 U.S. at 982 
(emphasis added)). Though, in Loper Bright, the Court declared that 
statutory stare decisis would protect specific regulations upheld under 
Chevron from future litigation challenges, the Court left open the 
possibility that the executive branch could itself depart from 
regulations that do not match the single, best meaning of the statute--
so long as the new regulations reflect that best meaning (see Loper 
Bright, 603 U.S. at 412). This makes particular sense given Loper 
Bright's focus on the propriety of executing the laws as written by 
Congress and the Executive Branch's constitutional obligation to ``take 
Care that the Laws be faithfully executed'' (U.S. Const. art. II, 
section 3).
    In light of their determination of illegality, the Services have 
determined that the best path forward is to rescind the regulatory 
definition entirely--instead of keeping part of it--and to refrain from 
implementing a replacement definition (see Dep't of Homeland Security 
v. Regents, 591 U.S. 1, 25 (2020)).\7\ We have also concluded--after 
careful consideration of the alternatives--that no replacement 
definition is needed.
---------------------------------------------------------------------------

    \7\ To be sure, the Services note that both Regents and State 
Farm involved two-pronged policies. Here, the Services' rescission 
involves a single regulatory definition.
---------------------------------------------------------------------------

    The Services understand that they are ``not writing on a blank 
slate,'' and thus the Services have considered reliance interests--
including those raised in public comments--in maintaining the existing 
definition or at least some definition (Regents, 591 U.S. at 33 
(requiring such consideration when agency is ``not writing on a blank 
slate'')). Below, the Services' responses to public comments address 
these reliance interests. At the outset, however, the Services 
acknowledge that the existence of a regulatory definition, as such, has 
provided some certainty to regulated entities. Further, the Services 
acknowledge that, in at least some circumstances, ``longstanding 
policies may have `engendered serious reliance interests that must be 
taken into account''' (Encino Motorcars, LLC v. Navarro, 579 U.S. 211, 
221-22 (2016) (quoting FCC v. Fox Television Stations, Inc., 556 U.S. 
502, 515 (2009))).
    Having taken these interests into account, the Services have 
concluded that such interests do not outweigh the need for a full 
rescission. The ESA itself defines ``take,'' which is the operative 
term prohibited under section 9 (16 U.S.C. 1532(19)). It is true that 
Justice Scalia's dissent in Sweet Home does not call into question the 
legality of the first sentence of the regulatory definition of 
``harm'': ``Harm in the definition of `take' in the Act means an act 
which actually kills or injures wildlife.'' But the current regulations 
were promulgated and amended as a single, integrated interpretive 
framework. The first sentence has functioned as the introductory clause 
to the more-elaborate restrictions that follow, and the Services have 
determined that those restrictions are unlawful. Thus, the Services 
believe that retaining even part of the unlawful regulation here would 
risk creating uncertainty about which aspects of the prior agency 
interpretations remain operative and which do not. Moreover, 
maintaining the first sentence on its own would not materially enhance 
regulatory clarity relative to the statutory text itself. In the 
Services' judgment, preserving that sentence as a standalone regulation 
therefore would provide limited independent guidance while risking 
confusion about the continuing legal significance of the rescinded 
portions of the regulation.
    Nor do the Services choose to add a new regulatory definition for 
``harm.'' Given that ``take'' is defined in the statute, and that the 
role and meaning of the term ``harm'' within the larger definition of 
``take'' was expertly explicated by Justice Scalia in his Sweet Home 
dissent--an interpretation which we have herein adopted--we find that 
maintaining a freestanding definition of ``harm'' is unnecessary. 
Moreover, at least in this situation and given the history detailed 
above, inserting a regulatory definition within a statutory definition 
that was otherwise clear appears to have been an attempt to arrogate to 
the Services authorities which Congress never granted. Returning to the 
statutory definition as the operative language is therefore especially 
appropriate.
    Because our regulations that define ``harm'' do not accord with the 
single, best meaning of the statutory text, the Services published a 
proposed rule in the Federal Register to rescind the definitions of 
``harm'' from title 50 CFR 17 and 222 (90 FR 16102, April 17, 2025). In 
that proposed rule, we provided background and rationale for rescinding 
the definitions of ``harm.'' We solicited public comments on the 
proposed rule through May 19, 2025.
    Following consideration of all public comments received in response 
to our proposed rule, and for the reasons outlined in our proposed rule 
and in this final rule, we are rescinding the regulatory definition of 
``harm.'' By finalizing the rescission of the regulatory definition of 
``harm,'' the Services are relying on the plain text of the statute as 
the standard going forward, but nothing in this final rule is intended 
to require that any prior permit or incidental take statement issued by 
the Services that relied on the prior definition of ``harm'' be 
reevaluated on the basis of this final regulation. Such incidental-take 
statements, and indeed the entire section 7 analysis, were but one 
input among many into the ultimate decision whether and how to 
authorize a given action (Cf. Seven Cnty. Infrastructure Coal. v. Eagle 
Cnty., Colorado, 605 U.S. 168, 180 (2025) (noting that an environmental 
impact statement issued under the National Environmental Policy Act is 
``only one input into an agency's decision,'' and that the ultimate 
locus of analysis, for purposes of administrative law, is ``the 
agency's final decision'')). Disturbing the finality of the overall 
permitting decision would be highly disruptive to settled expectations, 
as well as immensely time-consuming and difficult, in return for at 
most speculative gains. Therefore, permits or incidental take 
statements finalized prior to the effective date of this rule will not 
be required to be reevaluated under this final rule. (For the effective 
date of this rule, see DATES, above.)

Public Comments and Responses

    By the close of the public comment period on May 19, 2025, we 
received approximately 358,000 public comments on the proposed rule to 
rescind the regulatory definition of ``harm.'' Comments were received 
from a range of sources including individual members of the public, 
States, Tribes, industry organizations, legal foundations and firms, 
and environmental organizations. During the public comment period, we 
received multiple requests for public hearings. However, as public 
hearings are not required for this type of rulemaking, we elected not 
to hold them. We also received several requests for an extension of the 
30-day public comment period. After consideration, we determined that 
30 days provided sufficient time for the public to submit

[[Page 43303]]

meaningful comments and therefore we did not extend the comment period.
    Some commenters expressed support for the rule while other 
commenters requested that the proposed rule not be finalized. Among the 
submissions we received were multiple letters from organizations signed 
by individuals expressing general opposition to the proposed rule. Many 
of the individual comments we received were non-substantive in nature, 
expressing either general support for, or opposition to, the proposed 
rule with no supporting information or analysis. We also received many 
detailed substantive comments expressing support for, or opposition to, 
the proposed rule for specific reasons. All public comments were 
reviewed and considered prior to developing this final rule. Summaries 
of substantive comments and our responses are provided below. Similar 
comments are combined where appropriate. We did not, however, consider 
or respond to comments that are not relevant to or are beyond the scope 
of this particular rulemaking. For example, some commenters responded 
to unrelated Federal Register notices and proposed rulemakings (e.g., 
the U.S. Forest Service's Consent for Geothermal Leasing Project), 
congressional bills (e.g., H.R. 845 (Pet and Livestock Protection Act 
of 2025) and H.R. 1897 (ESA Amendments Act of 2025), or statutory 
provisions outside the ESA (e.g., Animal Welfare Act).
    Comment 1: Some commenters stated that Congress did not intend for 
the ESA prohibition on ``take'' to include habitat modification as 
defined under the term ``harm.'' They discussed that the legislative 
history show that ``take'' was meant to cover direct, affirmative 
actions against individual animals, not indirect, incidental, or 
unintentional impacts to species such as habitat modification or 
degradation. Several cited Justice Scalia's dissent in Sweet Home and 
the removal of habitat language from early drafts of the ESA as 
evidence that Congress deliberately chose to address habitat protection 
through other provisions, such as sections 5 and 7. Commenters stated 
that these sections were designed to address habitat conservation 
through land acquisition and Federal agency responsibilities, not 
through the ``take'' prohibition in section 9. Commenters also stated 
that the Services' current definition of ``harm'' unlawfully expands 
the scope of ``take'' beyond congressional intent and creates 
regulatory burdens that hinder land management and conservation 
practices. Other commenters disagreed, however, asserting that Congress 
intended ``harm'' to include habitat destruction or modification that 
indirectly or unintentionally results in injury or death to listed 
species. They pointed to the broad language of the ESA, its legislative 
history, and the statute's overarching goal stated in section 2 of the 
Act to conserve ecosystems upon which endangered and threatened species 
depend. Several commenters also stated that Congress deliberately 
included ``harm'' in the definition of ``take'' to broaden its scope 
beyond traditional notions of hunting or capturing, and that the 
Services' reinterpretation ignores this legislative intent.
    Response: The Services acknowledge the divergent views expressed by 
commenters relying on congressional intent. The Services recognize that 
the legislative history contains references both to direct actions 
against wildlife in section 9 and separately to broader ecosystem 
conservation goals in section 2. ``[L]egislative history,'' however, 
``is not the law'' (Epic Sys. Corp. v. Lewis, 584 U.S. 497, 523 
(2018)).
    Upon reevaluation and consideration of comments received, the 
Services have concluded that the regulatory definition of ``harm'' is 
not the single, best meaning of the text of the statute. As Justice 
Scalia's dissent in Sweet Home explains, the regulation's 
interpretation of the statutory language runs afoul of the noscitur a 
sociis canon, is inconsistent with the structure of the ESA, which 
provides distinct mechanisms for habitat protection under sections 5 
and 7, and disregards the absence of habitat-related language in the 
definition of ``take'' in section 3 itself. For more discussion, see 
Background, above. We also affirm our stated position in the proposed 
rule that no replacement definition is needed. The ESA itself defines 
``take,'' and the regulatory elaboration of one subcomponent of that 
definition -- ``harm''-- has had the effect of exceeding the proper 
bounds of the statute and asserting power that Congress never actually 
gave to the executive branch.
    ``Even if legislative history were a legitimate and reliable tool 
of interpretation,'' moreover, ``[b]oth the Senate and House floor 
managers of the bill explained it in terms which leave no doubt that 
the problem of habitat destruction on private lands was to be solved 
principally by the land acquisition program of section 1534, while 
section 1538 solved a different problem altogether the problem of 
takings'' (Sweet Home, 515 U.S. at 727-28 (Scalia, J., dissenting) 
(citing to relevant legislative history)). ``Habitat modification and 
takings, in other words, were viewed as different problems, addressed 
by different provisions of the Act'' (Id. at 728).
    Accordingly, the Services conclude that rescinding the regulatory 
definition of ``harm'' is consistent with the single, best reading of 
the ESA and with the statute's overall framework, which clearly 
distinguishes between prohibitions on ``take'' and broader habitat 
conservation responsibilities.
    Comment 2: Multiple commenters stated that the best reading of the 
ESA does not support the Services' proposed rule. Several commenters 
supported the rescission, citing the Supreme Court's decision in Loper 
Bright, which ended Chevron deference and emphasized that courts must 
apply the single, best reading of a statute. These commenters aligned 
with Justice Scalia's dissent in Sweet Home, asserting that ``take'' 
under the ESA refers only to direct, affirmative acts against 
individual animals themselves, not to indirect effects such as habitat 
modification. They opined that the current definition improperly 
extends liability to unintended consequences and lacks statutory 
grounding under section 9. Others, however, contended that the 
Services' proposal misreads the statute and ignores the ESA's 
structure, purpose, and legislative history. They asserted that habitat 
protection is central to the ESA, citing multiple statutory provisions 
and decades of judicial and agency interpretation affirming that 
``harm'' includes habitat destruction that results in injury or death 
to wildlife. These commenters stated that the Services' reliance on 
Sweet Home's dissent is misplaced, as the majority opinion upheld the 
current definition based on statutory text, purpose, and legislative 
history independent of Chevron. They also noted that Congress amended 
the ESA after Sweet Home without altering the definition of ``take,'' 
implicitly endorsing the broader interpretation. Overall, the comments 
reflect a divergence of opinions over whether the best reading of the 
ESA supports or rejects the inclusion of habitat modification in a 
definition of ``harm.''
    Response: After careful review of comments received, the Services 
have determined that the regulatory definition of ``harm'' runs 
contrary to the single, best reading of the ESA. As stated by Justice 
Scalia in his dissenting opinion in Sweet Home, the term ``take,'' 
defined in section 3, applies to actions that result in actual injury 
or death to listed species. The Services find that considering habitat 
degradation or modification that kills or

[[Page 43304]]

injures wildlife by significantly impairing improper essential 
behavioral patterns stretches the term ``harm'' beyond its natural 
meaning and creates overlap with other provisions of the ESA, such as 
sections 5 and 7, which are specifically designed to address habitat 
conservation.
    For more discussion, see Background, above, and our response to 
Comment 1. We reject the majority's interpretation of the ESA as 
articulated in Sweet Home. The Services conclude that rescinding the 
definition of ``harm'' supports the single, best reading of the ESA.
    Comment 3: Multiple commenters opined that the rescission of the 
definition of ``harm'' would weaken the effectiveness of section 7 
consultations by excluding incidental take resulting solely from 
habitat modification or degradation. They expressed concern that this 
narrower interpretation would lead to incomplete jeopardy analyses and 
undermine the legal and scientific basis for ``no jeopardy'' 
determinations. Commenters asserted that section 7 requires ongoing 
oversight and reinitiation of consultation when new information or 
changes in actions affect listed species or their designated critical 
habitat. They highlighted that incidental take statements are a 
critical mechanism for monitoring and limiting ``harm,'' and that these 
statements must include enforceable thresholds and measures to minimize 
impacts to species. Commenters also pointed to the legislative history 
of the ESA, asserting that Congress intended section 7 to encompass 
habitat-related impacts as a form of ``take,'' and that this intent is 
reflected in the statute's structure and amendments. They contended 
that rescinding the definition of ``harm'' and not considering habitat 
modification or degradation as a form of ``take'' would contradict this 
intent and reduce the ability of Federal agencies to ensure that their 
actions do not jeopardize listed species.
    Response: The rescission of the definition of ``harm'' does not 
alter the statutory requirement that Federal agencies ensure their 
actions are not likely to jeopardize the continued existence of listed 
species or ``result in the destruction or adverse modification of 
[critical] habitat of such species'' (16 U.S.C. 1536(a) (emphasis 
added)). ``Destruction or adverse modification'' is a separate 
regulatory consideration from ``take.'' Thus, not only is the statutory 
prohibition in section 7 against habitat modification not affected at 
all by the deletion of the definition of ``harm'' (which itself 
defines, in part, ``take''), but the presence of this separate and 
distinct provision in the statutory text regarding habitat modification 
reinforces the Services' conclusion that habitat modification is not 
properly part of the definition of ``take,'' as such a construction 
would violate the canon against surplusage. The Services emphasize that 
section 7 remains fully applicable to Federal actions that may affect 
listed species or their designated critical habitat. This rulemaking 
also does not change any species classifications or critical habitat 
designations.
    The rescission of the regulatory definition of ``harm'' does not 
limit the Services' ability to assess impacts to listed species and 
critical habitat from all components of the action agency's proposed 
action through the section 7 process. Yet, imposing the current 
incidental take regime on activities beyond those authorized by the 
statute is not an appropriate option that the Services believes they 
should avail themselves of (even if it were permissible under Loper 
Bright's dicta regarding the statutory-stare-decisis value of prior 
cases), given the executive branch's duty to see that the laws are 
faithfully executed. What commenters are suggesting is, in short, that 
we continue to subject a swath of activities to the incidental-take 
regime, which otherwise would not be subject to this regime on the best 
reading of the statute, simply because that would allow the Services to 
better monitor and accomplish some other goal, i.e., monitoring and 
limiting true ``harm.'' The Services reject this invitation as not 
being a proper implementation of the law, because it would impose 
burdens on the citizenry that are not authorized by statute.
    Comment 4: Multiple commenters stated that the proposed rescission 
of the definition of ``harm'' would significantly reduce the incentive 
for landowners to voluntarily seek permits under section 10(a) and 
would weaken the functional basis of section 10 permitting. They 
emphasized that the current definition of ``harm'' is essential for 
implementing habitat conservation plans (HCPs) and the associated 
incidental take permits (ITPs), as well as conservation benefit 
agreements (CBAs) and their associated enhancement of survival (EOS) 
permits. These tools provide regulatory assurances for landowners and 
enable proactive, voluntary conservation. Commenters warned that 
removing the definition would reduce incentives to seek ITPs, increase 
unpermitted ``take,'' and lead to greater habitat destruction. They 
also opined that the change would create legal uncertainty and diminish 
the effectiveness of conservation strategies, arguing that section 
10(a) permitting depends on a regulatory framework that recognizes 
habitat modification or degradation as a form of ``take.''
    Response: Commenters are correct that private parties seeking ITPs 
and EOS permits pursuant to section 10(a) of the ESA will no longer 
need to articulate the ``impact'' to species' habitat, explain how they 
will ``minimize and mitigate'' habitat modification or degradation, or 
consider alternatives in service of mitigating habitat modification or 
degradation in their conservation plans in order to obtain an 
incidental take permit. This rulemaking takes the position that the 
Services' requiring private parties to do so is unlawful, and thus 
impermissible for the agency to require.
    Relatedly, in issuing an incidental take permit, the Secretary of 
the Interior will no longer consider the effects of a proposed action 
on the species' habitat, nor will the permit contain terms and 
conditions requiring permittees to take into account habitat 
modification and degradation when executing the permitted take. Because 
the Services believe that the Act's prohibition on ``take'' does not 
properly include habitat modification (and thus have removed the 
regulatory definition of ``harm,'' which swept habitat modification 
into the statutory definition of ``take''), it follows that permits for 
incidental take are no longer required to engage in such activities. 
The attempt of at least one Commenter to argue that, because 
``conservation plans'' are mandated by section 10, therefore habitat 
conservation plans are mandated by statute (and, mutatis mutandis, ITPs 
and related instruments must account for habitat modification), gets 
the matter precisely backward (16 U.S.C. 1539(a)(1)(B) & (a)(2)(A)). 
The word ``habitat'' appears nowhere in section 10. Rather, section 
10's incidental-take regime is symmetrical to what would otherwise be 
take prohibited as ``take'' under section 9. If habitat modification 
were banned as take, then an ITP, along with a conservation plan and 
all the other requirements of section 10, would be necessary to modify 
such habitat. But because the Act does not ban habitat modification as 
take in the first place, therefore no ITP, conservation plan, or other 
instrument, is required to engage in such activities.
    The same Commenter also charged that the Services' regulations 
addressing HCPs are now ``inconsistent'' with the rescission. The 
Services are studying the extent to which its regulations governing 
such permits, e.g., 50 CFR 17.22, 17.32, may need to be updated to 
reflect this final rule and the best

[[Page 43305]]

reading of the Act, though the Services note also that other parts of 
the Act affect habitat modification, as noted in this final rule. In 
all events, this has not altered the Services' conclusion as to the 
best meaning of the text of the Act, which is what has driven this 
final rule.
    The rescission of the regulatory definition of ``harm'' does not 
eliminate the Services' ability to issue ITPs or EOS permits where 
there is an affirmative conduct intentionally directed against a 
particular animal or animals. Additionally, the Services will continue 
to work with applicants to ensure that HCPs and CBAs are developed and 
permitted to address species-specific impacts and that conservation and 
mitigation measures are commensurate with the ESA's definition of 
``take.''
    This rulemaking also does not prohibit willing landowners from 
implementing conservation plans and agreements that are more 
comprehensive than what sections 9 and 10 of the ESA require. Nor does 
this rulemaking prohibit entities (including state governments) from 
engaging in habitat-conservation efforts that could be supported by 
other provisions of the ESA.
    Comment 5: Multiple commenters opined that rescinding the 
regulatory definition of ``harm'' would introduce significant 
regulatory uncertainty and inconsistency in ESA implementation. They 
emphasized that the long-standing definition has provided clarity and 
stability for decades, supporting conservation programs, permitting 
frameworks, and legal agreements across agencies and stakeholders. 
Removing it without a clear alternative would lead to confusion, 
delays, litigation, and weakened conservation outcomes. Some of these 
commenters further asserted that the reasoning of Justice Scalia's 
dissent compelled the retention of the first sentence of the 
regulations, which--in these commenters' view--would be consistent with 
the Trump Administration's policy priorities. In contrast, some 
commenters supported the proposed rule, asserting that the current 
definition imposes excessive regulatory burdens, particularly through 
its inclusion of habitat modification. These supporters argued that 
rescission would reduce red tape, alleviate economic impacts on land 
use sectors, and allow for more targeted, science-based conservation 
efforts.
    Response: By rescinding the regulatory definition of ``harm,'' the 
Services are aligning the definition of ``take'' with the single, best 
reading of the statute, consistent with Loper Bright. Although the 
current definition of ``harm'' has been in place for decades, its 
inclusion of habitat modification or degradation where it actually 
kills or injures wildlife ``by significantly impairing essential 
behavioral patterns'' as a form of ``take'' has led to interpretive 
challenges and regulatory uncertainty, particularly in determining when 
habitat modification rises to the level of ``take.'' Although 
rescinding the definition of ``harm'' may reduce inconsistency and 
regulatory uncertainty by focusing on acts which actually kill or 
injure listed species, the Services are rescinding the definition of 
``harm'' because it does not accord with the best meaning of the 
statute. The Services have also concluded that no replacement 
definition is needed. The ESA itself defines ``take'' (16 U.S.C. 
1532(19)), and that definition is clear and robust.
    By rescinding the definition of ``harm,'' the Services are relying 
on the plain text of the statute as the standard going forward. But 
previously issued permits or incidental take statements will not be 
required to be reevaluated solely because of this final rule, nor does 
this final rule invalidate prior conservation agreements or other 
conservation or recovery efforts already in effect. Such incidental-
take statements, and indeed the entire section 7 analysis, were but one 
input among many into the ultimate decision whether and how to 
authorize a given action (Cf. Seven Cnty. Infrastructure Coal. v. Eagle 
Cnty., Colorado, 605 U.S. 168, 180 (2025) (noting that an environmental 
impact statement issued under the National Environmental Policy Act is 
``only one input into an agency's decision,'' and that the ultimate 
locus of analysis, for purposes of administrative law, is ``the 
agency's final decision'')). Disturbing the finality of the overall 
permitting decision would be highly disruptive to settled expectations, 
as well as immensely time-consuming and difficult, in return for at 
most speculative gains. Moreover, the regulations governing HCPs 
include assurances to permittees in case of changed or unforeseen 
circumstances (see 50 CFR 17.22(b)(5), 17.32(b)(5)). The Services have 
considered that these regulations reassure permittees that the Services 
would not impose additional requirements,\8\ whereas rescinding the 
definition of harm might in some situations lessen existing burdens 
(e.g., if the permittee is mitigating only for habitat impacts that 
were considered prohibited as take when their permit was issued, the 
permittee may choose to return their permit in order to not have to 
continue expending resources to mitigate). Nonetheless, such situations 
are speculative, while the central offer of these regulations to 
permittees is repose and certainty. These values counsel very 
strongly--and decisively--against not disturbing previously issued 
permits.
---------------------------------------------------------------------------

    \8\ E.g., 50 CFR 17.22(b)(5)(iii)(A) (``In negotiating a 
response to unforeseen circumstances, the Director will not require 
the commitment of additional land, water, or financial compensation 
or additional restrictions on the use of land, water, or other 
natural resources beyond the level otherwise agreed upon for the 
species covered by the conservation plan without the consent of the 
permittee.'').
---------------------------------------------------------------------------

    Comment 6: Multiple commenters requested that if the Services 
finalize the proposed rule, they must issue clear guidance on how 
``harm'' and ``take'' will be interpreted and applied. Commenters 
emphasized that without a regulatory definition, the regulated 
community faces uncertainty about what actions may constitute ``take'' 
under section 9 and when particular requirements will need to be met, 
especially in section 7 consultations and permitting under section 
10(a). Commenters requested examples and clarification to ensure 
consistent implementation and avoid delays or inconsistent decisions. 
They also urged the Services to confirm how the rule applies to pending 
consultations and to update existing guidance documents or include 
clarifications in the final rule's preamble.
    Response: The definition of ``take'' in section 3 of the Act 
remains unchanged and will stand on its own as the best reading of the 
Act. In addition, under the noscitur a sociis canon, the term ``harm,'' 
like the other nine verbs in the definition of ``take,'' should be 
construed to require an ``affirmative act[] . . . directed immediately 
and intentionally against a particular animal--not [an] act[] or 
omission[] that indirectly and accidentally cause[s] injury to a 
population of animals'' (515 U.S. at 719-720).
    The Services intend to review each specific situation and species' 
response to a proposed action to determine whether it may or may not 
constitute ``harm'' to a species. As stated above, this rule is setting 
prospective standards only; previously issued permits or incidental 
take statements will not be required to be reevaluated solely because 
of this final rule. Such incidental-take statements, and indeed the 
entire section 7 analysis, were but one input among many into the 
ultimate decision whether and how to authorize a given action (Cf. 
Seven Cnty. Infrastructure Coal. v. Eagle Cnty., Colorado, 605 U.S. 
168, 180 (2025)). Disturbing the finality of the overall permitting 
decision would be highly

[[Page 43306]]

disruptive to settled expectations, as well as immensely time-consuming 
and difficult, in return for at most speculative gains. For more on 
this rule's impact on future section 10(a) permits, see the Services' 
responses to Comments 5 and 20. For a description of the ways in which 
this rule does not impact future section 7 consultations, see the 
Services response to Comment 4.
    The Services also acknowledge that reliance interests have built up 
around this regulatory definition. Rescinding the regulatory 
definition--without a replacement at this time--promotes the lawful 
operation of executive branch regulatory programs, and the Services 
believe that this core value outweighs the reliance interests that have 
built up around the continued maintenance of an unlawful regulatory 
definition, even if such were possible. For further responses to 
reliance interests, see Comments 13, 16, 18, 20, and 21.
    Comment 7: Multiple commenters stated that removing habitat 
modification from the definition of ``take'' would severely weaken the 
Act's ability to protect imperiled species. They emphasized that 
significant habitat modification or degradation often results in injury 
or death to wildlife by impairing essential behaviors such as feeding, 
breeding, and sheltering. Without recognizing these indirect but 
biologically consequential impacts as ``take,'' the Services would be 
unable to regulate many of the most common and damaging threats to 
species survival. Commenters stated that habitat loss is the leading 
driver of species decline and extinction and excluding it from the 
definition of ``take'' would eliminate a critical legal mechanism for 
preventing such outcomes. They wrote that by narrowing the scope of 
what qualifies as ``take,'' the Services would be forced to ignore the 
ecological realities that species cannot survive without intact, 
functional habitats. Commenters stated that this shift would not only 
violate the purpose of the ESA but also increase the likelihood of 
extinction for many species by allowing habitat destruction to proceed 
without consequence.
    Response: The Services emphasize that the rescission of the 
regulatory definition of ``harm'' does not diminish the importance of 
habitat loss or degradation as a significant threat to many species 
listed under the ESA. Habitat protection and conservation play a 
critical role in species conservation and recovery efforts. Rather, 
this rule clarifies that ``take'' applies only to an ``affirmative 
act[] . . . directed immediately and intentionally against a particular 
animal--not [an] act[] or omission[] that indirectly and accidentally 
cause[s] injury to a population of animals'' (515 U.S. at 719-20 
(Scalia, J., dissenting)). Habitat-related impacts are considered and 
addressed under other provisions of the ESA, including section 7 
consultations section 5 land acquisition, and cooperation with willing 
landowners through voluntary conservation programs. The Services will 
continue to use these tools to address threats to species and to help 
chart the path to recovery and delisting. The rescission of the 
definition of ``harm'' intends to align the implementation of the Act 
with the single, best reading of the statute by making clear that 
habitat modification or degradation does not qualify as ``take.''
    Comment 8: Multiple commenters opined that the proposed rule's 
basis for rescinding the definition of ``harm'' directly undermines the 
purpose and function of critical habitat designations under the ESA. 
They emphasized that critical habitat is essential for species survival 
and recovery, and rescinding the definition of ``harm'' would lead to 
increased degradation of these areas, pushing species closer to 
extinction. Commenters also contended that the rule would violate the 
agencies' statutory duties to designate and protect critical habitat. 
They disagreed with the reliance on a narrow legal interpretation that 
disregards the legislative history and structure of the ESA, 
particularly the 1982 amendments that clarified the importance of 
habitat in incidental take authorizations. These amendments, they 
stated, affirm that impacts to habitat can constitute ``take'' and that 
section 7 requires Federal agencies to avoid actions that would destroy 
or adversely modify critical habitat. Commenters maintained that 
without a regulatory definition of ``harm'' that includes habitat 
modification or degradation, the Services would not be able to minimize 
effects to critical habitat.
    Response: The Services recognize the importance of critical habitat 
designations in promoting the conservation and recovery of listed 
species. The definition of critical habitat in section 3(5)(A) and the 
process and requirements of designating critical habitat in section 
4(b)(2) of the Act will remain separate and distinct from the 
definition of ``take'' in section 3.\9\ The rescission of the 
regulatory definition of ``harm'' does not alter the statutory 
obligations for the Services to use the best scientific data available 
to designate critical habitat under section 4(b)(2) of the Act.
---------------------------------------------------------------------------

    \9\ Indeed, the presence of these separate and distinct 
provisions in the statutory text regarding habitat modification 
reinforces the Services' conclusion that habitat modification is not 
properly part of the definition of ``harm'' and, thus, of ``take,'' 
as such a construction would violate the canon against surplusage.
---------------------------------------------------------------------------

    The Services maintain that habitat protection remains a central 
component of the ESA's conservation framework. This rescission has no 
impact on the requirements of Federal agencies under section 7(a)(2) to 
avoid the destruction or adverse modification of designated critical 
habitat. We will continue to analyze effects to the physical or 
biological features of designated critical habitat.
    The Services conclude that ``take'' applies only to an 
``affirmative act[] . . . directed immediately and intentionally 
against a particular animal--not [an] act[] or omission[] that 
indirectly and accidentally cause[s] injury to a population of 
animals'' (515 U.S. at 719-20 (Scalia, J., dissenting)). We do not find 
persuasive the argument that the 1982 amendments to the ESA, which 
allowed the Secretary of the Interior to issue incidental take permits, 
suggests that Congress understood section 9 to prohibit indirect as 
well as deliberate takings. Habitat modification is not the only 
activity that might incidentally cause a prohibited taking. For 
example, fishing for unprotected salmon may inadvertently but 
unavoidably cause takes of an endangered species of salmon (515 U.S. at 
729).
    Comment 9: Commenters contended that the Services misinterpreted 
Loper Bright as exempting interpretive rulemakings from the National 
Environmental Protection Act (NEPA; 42 U.S.C. 4321 et seq.). They 
stated that the decision addressed judicial review, not agency 
obligations, and that the Services remain bound by prior precedent, 
including Sweet Home, until overturned by the courts.
    Response: Loper Bright did not alter or exempt agencies from their 
responsibilities under NEPA. The Services do not rely on Loper Bright 
to justify the use of a categorical exclusion in this rulemaking. 
Rather, the Services have independently evaluated the applicability of 
NEPA and determined that the rule qualifies for a categorical exclusion 
under 43 CFR 46.210(i) and the U.S. Department of the Interior Handbook 
of National Environmental Policy Act Implementing Procedures, appendix 
2. As the Services noted in the proposed version of this rule, two 
recent proposed and final rulemakings addressing a regulatory 
definition of ``habitat'' under the Endangered Species Act found that 
these categorical exclusions applied. See Endangered and

2020; Endangered and Threatened Wildlife and Plants; Regulations for

Habitat, 85 FR 47333, August 5, 2020.
    The Services have also concluded that, because this rescission is 
compelled by the best reading of the statutory text, ``the proposed 
agency action is a nondiscretionary action with respect to which such 
agency does not have authority to take environmental factors into 
consideration in determining whether to take the proposed action.'' (42 
U.S.C. 4336(a)(4); see Dep't of Transp. v. Pub. Citizen, 541 U.S. 752, 
766-70 (2004)).
    Our rescission of the regulation definition of ``harm'' on the 
ground that it does not reflect the best reading of the statutory text 
effectuates the Executive Branch's obligation to ``take Care that the 
Laws be faithfully executed,'' U.S. Const. art. II, section 3, and is 
consistent with Loper Bright and Sweet Home. At bottom, the Services 
are engaged in legal interpretation, and the Services have determined 
that the bottom-line policy here (the rescission of the regulations) is 
nondiscretionary in light of the regulations' unlawfulness, even if the 
interstitial particulars of effectuating that policy (e.g., whether to 
rescind the whole regulation and whether to implement a new definition, 
regardless of what it would say) require an exercise of discretion that 
has nothing to do with environmental factors.
    Comment 10: Several commenters challenged the Services' use of a 
categorical exclusion, asserting that the proposed rule is not merely 
procedural and will have significant environmental effects. They opined 
that the Services failed to justify the categorical exclusion and did 
not evaluate whether extraordinary circumstances apply.
    Response: The Services considered whether the proposed rule 
qualifies for a categorical exclusion and whether any extraordinary 
circumstances exist that would preclude its use. The Services 
determined that the proposed agency action is non-discretionary, and in 
the alternative, that the proposed regulation changes themselves will 
not have a significant individual or cumulative effect on the quality 
of the human environment for purposes of NEPA--notwithstanding 
potential indirect follow-on economic impacts or impacts on small 
entities (Cf. Seven Cnty. Infrastructure Coal. v. Eagle Cnty., 605 U.S. 
148, 183 (2025) (``A reviewing court may not `substitute its judgment 
for that of the agency as to the environmental consequences of its 
actions.''' (quoting Kleppe v. Sierra Club, 427 U.S. 390, 410 n.21 
(1976)))). The Services have applied a categorical exclusion to comply 
with the NEPA. As the Services noted in the proposed rulemaking and 
above, two recent proposed and final rulemakings addressing a 
regulatory definition of ``habitat'' under the Endangered Species Act 
found that the exact same categorical exclusions invoked in this 
rulemaking applied. See Endangered and Threatened Wildlife and Plants; 
Regulations for Listing Endangered and Threatened Species and 
Designating Critical Habitat, 87 FR 37757, June 24, 2022; Endangered 
and Threatened Wildlife and Plants; Regulations for Listing Endangered 
and Threatened Species and Designating Critical Habitat, 86 FR 59353, 
October 27, 2021; Endangered and Threatened Wildlife and Plants; 
Regulations for Listing Endangered and Threatened Species and 
Designating Critical Habitat, 85 FR 81411, December 16, 2020; 
Endangered and Threatened Wildlife and Plants; Regulations for Listing 
Endangered and Threatened Species and Designating Critical Habitat, 85 
FR 47333, August 5, 2020. The Services have determined that 
extraordinary circumstances do not apply. For a detailed discussion of 
the Services' NEPA analysis see National Environmental Policy Act in 
the Required Determinations section, below, and the environmental 
action statement and supporting categorical exclusion documentation 
available at https://www.regulations.gov in Docket No. FWS-HQ-ES-2025-
0034.
    Comment 11: One commenter stated that the Services' failure to 
prepare an EIS violates NEPA, citing Sierra Club v. Marsh, 816 F.2d 
1376, 1387 (9th Cir. 1987), as precedent. They emphasized that the 
proposed rule would significantly affect the human environment by 
weakening habitat protections for endangered species, which-in their 
view-meets the threshold for requiring an EIS. Commenters noted that 
Sierra Club v. Marsh established that agencies must assess 
environmental impacts before making irreversible commitments, and that 
deferring such analysis undermines NEPA's core purpose. They asserted 
that the Services' reliance on categorical exclusions or claims of 
nondiscretionary action does not meet the legal standard set by this 
case.
    Response: The Services respectfully disagree with the assertion 
that the proposed rule constitutes an irreversible commitment of 
resources or a major Federal action with significant environmental 
effects. This rule does not, by itself, authorize any specific activity 
or project. It does not alter the statutory requirements of the ESA, 
including the obligation of Federal agencies to consult under section 7 
and to avoid jeopardizing listed species or adversely modifying 
critical habitat. The Services have determined that the rule qualifies 
for a categorical exclusion and that no extraordinary circumstances 
exist that would warrant preparation of an EIS.
    Comment 12: Multiple commenters contended that the Services are 
exercising discretion in proposing to rescind the definition of 
``harm,'' and therefore cannot claim the action is nondiscretionary to 
avoid NEPA review. They emphasized that interpreting statutory language 
involves judgment, and that NEPA applies to discretionary actions with 
potential environmental impacts.
    Response: The Services acknowledge the comments asserting that the 
proposed rule is a discretionary action. As the Services stated in the 
proposed rule, we are undertaking this recission because we believe it 
is compelled by the best reading of the statutory text. Accordingly, we 
believe that ``the proposed agency action is a nondiscretionary action 
with respect to which such agency does not have authority to take 
environmental factors into consideration in determining whether to take 
the proposed action'' (42 U.S.C. 4336(a)(4); see Dep't of Transp. v. 
Pub. Citizen, 541 U.S. 752, 766-70 (2004)).
    Moreover, commenters have cited no case, and the Services are aware 
of none, standing for the proposition that NEPA review applies to 
questions of pure legal interpretation. This would be a novel 
interpretation that would dramatically expand the scope of NEPA--e.g., 
does it cover briefing in pending cases--and the Services will not, 
without more, adopt this new proposition.
    In the alternative, the Services applied a categorical exclusion to 
comply with NEPA. The Services have determined that the rule qualifies 
for a categorical exclusion because it is ``of an administrative, 
financial, legal,

[[Page 43308]]

technical or procedural nature'' (43 CFR 46.210(i)). The Services have 
also evaluated whether any extraordinary circumstances apply and have 
concluded that none are present. Accordingly, the use of a categorical 
exclusion is appropriate and consistent with NEPA and applicable agency 
regulations and procedures. As the Supreme Court recently held in Seven 
County Infrastructure Coal. v. Eagle County, Colorado, ``NEPA is a 
purely procedural statute,'' ``not a substantive roadblock,'' and is an 
area where ``substantial deference'' is due to ``agency choices so long 
as they fall within a broad zone of reasonableness'' (605 U.S. 168, 
173, 183 (2025); see id. at 182-83 (``When assessing significant 
environmental effects and feasible alternatives for purposes of NEPA, 
an agency will invariably make a series of fact-dependent, context-
specific, and policy-laden choices about the depth and breadth of its 
inquiry . . . . Courts should afford substantial deference and should 
not micromanage those agency choices so long as they fall within a 
broad zone of reasonableness.'')). To the extent NEPA applies at all to 
this question, the Services believe it is readily satisfied by the 
existing categorical exclusion, which has, moreover, been repeatedly 
applied, under the administrations of Presidents of both major 
political parties, to rulemakings in this exact area, see responses to 
Comments 9 and 10.
    Comment 13: Multiple commenters stated that the Services' 
rescission of the regulatory definition of ``harm'' is arbitrary and 
capricious under the APA. Commenters asserted that the Services did not 
provide a detailed justification for this reversal, nor did they 
address the serious reliance interests built around the existing 
definition. Commenters opined that rescinding the current definition of 
``harm'' switches course on decades of regulatory and judicial 
interpretation, including the Supreme Court's majority opinion in Sweet 
Home. Commenters asserted that the proposal appears to be driven by 
political motivations rather than sound reasoning or legal necessity, 
and that it lacks the transparency and consistency required by the APA.
    Response: The Services disagree with the characterization of this 
rule as arbitrary and capricious under the APA. The rule is based on a 
reevaluation of the statutory text of the ESA. The Services' rescission 
of the regulatory definition of ``harm'' on the ground that it does not 
reflect the best reading of the statutory text effectuates the 
Executive Branch's obligation to ``take Care that the Laws be 
faithfully executed'' (U.S. Const. art. II, section 3).
    In proposing to rescind our regulatory definition of ``harm,'' the 
Services noted that they were ``considering whether there are 
legitimate reliance interests on the regulations under reexamination,'' 
but that ``because it is the President's duty to see that the laws are 
faithfully executed, in all but the most unusual cases, we believe that 
reliance interests likely will be outweighed by the constitutional 
interest in repealing regulations that do not reflect the best reading 
of the statute.'' 90 FR 16102, at 16104, (citing Dep't of Homeland Sec. 
v. Regents of the Univ. of California, 591 U.S. 1, 30-32 (2020; 
Regents)). We asked for comment on reliance interests specifically 
(Id.). After reviewing comments we received on reliance interests, the 
Services affirm that reliance interests are outweighed by the 
constitutional interest in repealing regulations that do not reflect 
the best reading of the statute.
    Commenters raised four principal arguments regarding reliance 
interests. The first is the reliance interests of those who provide 
services related to mitigation. Commenters noted that if habitat 
modi[filig]cation is no longer regulated under section 9 of the ESA, 
then conservation-financing, species-mitigation, and habitat-
restoration markets, participation in which was once necessary to 
obtain an incidental take permit under section 10 of the ESA, will be 
eliminated. The appetite for these services among permittees will 
disappear, leaving existing and pending offsets as essentially stranded 
investments without a market. Commenters estimated approximately $483 
million has been spent to date on species habitat and that the proposed 
rescission alone has chilled an additional $300 million in planned 
investments. Additionally, commenters stated the broader economic 
impact of habitat-restoration activities is estimated to approach $10 
billion overall and supports more than 53,000 jobs.
    The Services recognize that a restoration and mitigation industry 
has developed under the prior regulatory framework. Commenters are 
correct that changes in the regulatory system may influence market 
demand for certain mitigation efforts focused on habitat conservation 
that were once necessary to obtain an incidental take permit under 
section 10 of the ESA. As noted in the preamble, the magnitude of such 
impacts is uncertain and not amenable to reliable quantification. What 
is more, however, is that the services sold in these markets are 
essentially regulatory rents. Where there is no justification in law 
for imposing the relevant regulation, imposing such costs is inherently 
illegitimate--and pleas to keep them, though cast in the form of 
reliance interests, are essentially rent-seeking. The Services 
therefore, in accord with Regents, has decided that ``reliance 
interests in benefits [i.e., regulatory rents] that it views as 
unlawful are entitled to no or diminished weight'' (591 U.S. at 32). 
This reliance interest is addressed further at Comment 21.
    The second, and closely related, class of reliance interests 
articulated by comments is that of those who sell services related to 
voluntary conservation programs, multi-year HCPs (including the 
investment in planning for an HCP, the investment in implementing the 
HCP, and land management practices, including voluntary conservation 
measures. Commenters noted that, if habitat modification is no longer 
regulated as ``take'' under section 9, then such services will no 
longer be needed to obtain an incidental take permit under section 10, 
and, as a result, their market will dry up.
    The Services recognize that these industries had developed under 
the prior regulatory framework. Commenters are correct that changes in 
the regulatory system may influence market demand for certain 
mitigation efforts focused on habitat conservation that were once 
necessary to obtain an incidental take permit under section 10 of the 
ESA. This revision is prospective only and does not affect permits that 
have been granted as of the date this rule becomes final. That is, no 
conservation agreement or habitat management plan that is in effect as 
of the date of this rule becomes final will be affected by it. Going 
forward, the Services intend to review each specific situation and 
species' response to a proposed action to determine whether it may or 
may not constitute ``harm'' to a species pursuant to section 3 of the 
ESA. The Services will continue to work with applicants to ensure that 
HCPs and CBAs are developed and permitted to address species-specific 
impacts and that conservation and mitigation measures are commensurate 
with the ESA's definition of ``take.'' This rulemaking does not 
prohibit willing landowners from implementing conservation plans and 
agreements that are more comprehensive than what sections 9 and 10 of 
the ESA require. However, yet again, beyond situations in which private 
persons voluntarily wish to purchase such mitigation services or need 
to purchase them to satisfy other provisions of law, the

[[Page 43309]]

market for such services under sections 9 and 10 is a creation of 
regulations that, in the view of the Services, are not authorized by 
law--and that, as such, the services sold in these markets are 
essentially regulatory rents. Where there is no justification in law 
for imposing the relevant regulation, imposing such costs is inherently 
illegitimate--and pleas to keep them, though cast in the form of 
reliance interests, are essentially rent-seeking. The Services 
therefore, in accord with Regents, has decided that ``reliance 
interests in benefits [i.e., regulatory rents] that it views as 
unlawful are entitled to no or diminished weight'' (591 U.S. at 32). 
This reliance interest is addressed further at Comment 18.
    The third main class of reliance interests articulated by 
commenters is that of persons interested in the protection of wildlife 
and habitats. Commenters noted that habitat protections were important 
to ecological stability, ecosystem services, pollination, and clean 
water; that aesthetic and recreational interests would be injured; that 
the wildlife-watching industry would be damaged; and that the sport-
fishing industry would suffer.
    The Services emphasize that the rescission of the regulatory 
definition of ``harm'' does not diminish the importance of habitat loss 
or degradation as a significant threat to many species listed under the 
ESA. Habitat protection and conservation play a critical role in 
species conservation and recovery efforts. Rather, this rule clarifies 
that ``take'' applies only to actions that cause actual injury or death 
to listed species. Habitat-related impacts are considered and addressed 
under other provisions of the ESA, including section 7 consultations, 
critical habitat designations, section 5 land acquisition authorities, 
and cooperation with willing landowners through voluntary programs. The 
Services will continue to use these tools to address threats to species 
and to help chart the path to recovery and delisting. The rescission of 
the definition of ``harm'' intends to align the implementation of the 
Act with the single, best reading of the statute by removing habitat 
modification or degradation as a form of prohibited ``take.'' This 
rulemaking does not prohibit willing landowners from implementing 
conservation plans and agreements that are more comprehensive than what 
sections 9 and 10 of the ESA require. Beyond these responses, the 
Services note that much of what such Commenters are casting as reliance 
interests are really policy disagreements: Commenters wish that 
Congress had, or the Administration would continue to, set the balance 
between habitat preservation and the rights of landowners differently 
than, in the Service's view, the Act in fact does. The Services are 
determined, by contrast, to adhere to what is in their view the best 
reading of the law.\10\ These comments are addressed further at 
Comments 18 and 20.
---------------------------------------------------------------------------

    \10\ One commenter also argued that animal rescue programs would 
be increasingly burdened, because without habitat modification being 
included in the definition of ``harm,'' more animals would be hurt 
and need rescue. As for effects to Animal Rescue Programs, 
rescinding the regulatory definition of ``harm'' will not negate the 
fact that actions that directly result in injury or death to listed 
wildlife still constitutes ``take'' under the ESA. This rule would 
not result in the large-scale habitat changes that the commenter 
asserts would result in higher instances of animal injury. As stated 
above, habitat-related impacts will be addressed under other 
provisions of the ESA.
---------------------------------------------------------------------------

    The fourth main class of reliance interests articulated by comments 
is that of State reliance interests: States wrote to claim that the 
existing definition of harm bolsters state laws, or that states rely on 
Federal definition of harm when state does not have a law on point, and 
that in any event, the existence of the current federal definition of 
harm has ensured consistency across state lines.
    The Services respond that the rescission of the definition of 
``harm'' in the Act does not alter the ability of States to implement 
their own conservation programs or to regulate habitat impacts under 
State law. Federal law and regulations create a legal floor (or minimum 
standard). Congress preserved the authority of any state to enact and 
enforce laws or regulations that provide species protections more 
stringent than federal protections while maintaining the ESA's 
preemption over any state law that would permit what is prohibited 
under the ESA or prohibit what is authorized under the ESA (16 U.S.C. 
1535(f)). Nor does this final rule affect the Services' commitment to 
cooperative federalism and coordination with State agencies, which 
takes place pursuant to section 6 cooperative agreements, section 10(a) 
permits, and section 7 consultations, not through the implementation of 
section 9 take prohibitions. For example, section 6 of the ESA permits 
the Secretary of the Interior to ``enter into agreements with any State 
for the administration and management of any area established for the 
conservation of endangered species or threatened species'' (16 U.S.C. 
1535(b)). The Secretary of the Interior may also enter into agreements 
with States, that ``establish[ ] and maintain[ ] an adequate and active 
program for the conservation of endangered species and threatened 
species'' and plants (Id. at 1535(c)).\11\ This rule does not change 
any species or critical habitat designations. The Services will 
continue to work with States to support species recovery and habitat 
protection through section 6 cooperative agreements, section 7 
consultations, and other collaborative mechanisms. Beyond these 
responses, though, the Services note that much of what these state 
commenters are casting as reliance interests are really policy 
disagreements: These states wish that Congress had, or the 
Administration would continue to, set the federal floor differently 
than, in the Service's view, the Act in fact does. The Services are 
determined, by contrast, to adhere to what is in their view the best 
reading of the law. Indeed, in this particular context, federalism 
concerns counsel heavily in favor of rejecting these states' purported 
reliance interests, for if the federal government were to maintain the 
elevated federal floor these states request (and which is not 
authorized by the best reading of the statute), other states would not 
have any freedom to try other approaches. These comments are addressed 
further at Comment 16.
---------------------------------------------------------------------------

    \11\ The Services note, again, that the explicit provisions for 
habitat protection in so many other parts of the ESA reinforces 
their conviction that the portion of section 9 forbidding ``take'' 
was not meant to address habitat modification.
---------------------------------------------------------------------------

    To return to the commenters' overall point, the Services hold that 
reliance on an unlawful regulatory definition is unjustified because 
the regulatory certainty provided by an unlawful definition is 
illegitimate. Thus, the Services do not believe that these reliance 
interests overcome the executive branch's important interest in 
maintaining and enforcing only lawful regulations. The Services believe 
that a full rescission, without the implementation of a replacement 
definition at this time, best achieves this interest. The Services 
understand that at least one court has stated that ``an agency must 
always consider serious reliance interests, even when it concludes an 
earlier policy was unlawful,'' but that the agency may determine that 
such reliance interests ``are entitled to no or diminished weight'' 
because of the unlawfulness of the earlier policy (A.C.R. v. Noem, 809 
F. Supp. 3d 103, 122 (E.D.N.Y. 2025)). The Services have considered the 
reliance interests and determined that they are entitled to no or 
diminished weight.
    The Services further acknowledge the well-established principle 
that when an agency changes position, ``provid[ing]

[[Page 43310]]

reasoned explanation'' has required that the agency ``display awareness 
that it is changing position'' and ``show that there are good reasons 
for the new policy'' (FCC v. Fox Television Stations, Inc., 556 U.S. 
502, 515 (2009)). We have satisfied that requirement in making this 
final decision. In the Services' proposed rule, the Services included a 
discussion of the statutory framework, Sweet Home, and our rationale 
for concluding that the definition of ``harm'' does not support the 
best meaning of the Act, the specific proposed regulation change, and 
asked for public comment. We have now reviewed the public comments and 
in this final rule have provided responses to unique, substantive 
comments. Thus, the process that we used to promulgate this rule 
complied with the applicable requirements of the APA.
    Comment 14: Multiple commenters asserted that the Services' 
proposal lacks the reasoned analysis required by the APA, as 
articulated in Motor Vehicle Manufacturers Ass'n v. State Farm Mutual 
Automobile Ins. Co., 463 U.S. 29 (1983; State Farm). They assert that 
the Services failed to examine relevant information or provide a 
satisfactory explanation for abandoning the longstanding definition of 
``harm.'' Commenters stated that the Services did not assess the 
impacts of the change on species conservation, habitat protection, or 
regulatory programs such as ITPs and HCPs. Instead, they assert that 
proposal relies on a narrow legal rationale and a misreading of recent 
case law, without addressing the statutory purpose of the ESA or the 
practical consequences of the change. Commenters concluded that this 
failure to consider important aspects of the problem and to offer a 
rational connection between the facts found and the choice made renders 
the proposal legally deficient under State Farm.
    Response: The Services respectfully disagree that the proposed rule 
lacks the reasoned analysis required under the APA. To begin, 
commenters appear to misapprehend the nature of the arbitrary-and-
capricious standard. That standard simply ``requires that agency action 
be reasonable and reasonably explained'' (FCC v. Prometheus Radio 
Project, 592 U.S. 414, 423 (2021)). ``Judicial review under that 
standard is deferential'': ``A court simply ensures that the agency has 
acted within a zone of reasonableness and, in particular, has 
reasonably considered the relevant issues and reasonably explained the 
decision'' (Id.). In accordance with State Farm, the Services have 
provided a reasoned explanation for the proposed rescission of the 
regulatory definition of ``harm.'' The Services explained that they 
were rescinding the regulatory definition of ``harm'' because it does 
not reflect the best reading of the ESA. This includes a detailed 
analysis of the statutory text, structure, and purpose of the ESA, as 
well as the legal implications of the Supreme Court's decision in Loper 
Bright. That is a complete explanation that satisfies State Farm. The 
Services have also now considered public comments received. This rule 
reflects the agency's view of the best interpretation of the ESA, which 
does not permit agencies to factor in habitat modification or 
degradation in the context of section 9 prohibited take. The Services 
have addressed reliance interests, including reliance interests of 
those involved in regulatory programs such as ITPs and HCPs, throughout 
responses to comments, including the Services' responses to Comments 5, 
13, 20, and 23. The Services have satisfied their obligations under the 
arbitrary-and-capricious standard and State Farm.
    Comment 15: Multiple commenters contended that the Services must 
conduct intraservice consultation under section 7 of the ESA before 
finalizing the proposed rescission of the definition of ``harm.'' They 
asserted that the action is not exempt from consultation requirements 
and may adversely affect numerous listed species, particularly those 
species where the primary threat is habitat loss. Commenters cited the 
Endangered Species Consultation Handbook and joint regulations, which 
require consultation for agency actions, including rulemakings, that 
may affect listed species or critical habitat. They asserted that the 
Services must prepare a biological opinion evaluating species-specific 
impacts and ensure the action does not jeopardize species' continued 
existence.
    Response: As stated in the Required Determinations section, below, 
the Services are acting in their unique statutory role as 
administrators of the Act and are engaged in a legal exercise of 
interpreting the standards of the Act. The Services' administration of 
the Act is not in itself subject to the Act's provisions, including 
section 7(a)(2). The Services have a historical practice of issuing 
their general regulations under the ESA without undertaking section 7 
consultation (see Endangered Species Act in the Required Determinations 
section below). This practice accords with the plain language, 
structure, and purposes of the ESA, which does not place a consultation 
obligation on the Services' administration of the Act. Furthermore, 
from a pragmatic point of view, the proposed consultation requirement 
would be impracticably elaborate, even nonsensical. Were commenters 
correct, the Services would be required to conduct an analysis as to 
every single endangered species on the list and speculate as to how the 
new legal definition would produce different consequences as to each--
as section 7 still mandated habitat protection through an entirely 
different regime that this rule does not touch, see the Services' 
response to Comment 3. Little wonder, then, that such a recursive and 
reticulated procedure was not undertaken when this rule was promulgated 
in 1975 and has never been the Services' practice when it comes to 
changes to the ESA implementing regulations themselves.
    Comment 16: Multiple commenters asserted that the proposed rule 
would create significant inconsistencies with existing State 
regulations and undermine State-led conservation efforts. Many states, 
such as New Mexico and Oregon, have developed their own definitions of 
``take'' or ``harm'' that include habitat modification as a key 
component. Commenters opined that the recission would weaken State 
protections, disrupt established conservation frameworks, and 
jeopardize long-standing agreements. Commenters emphasized that this 
change would introduce regulatory uncertainty, delay conservation 
planning, and reduce the effectiveness of State investments in species 
conservation and habitat protection.
    Response: The rescission of the definition of ``harm'' in the Act 
does not alter the ability of States to implement their own 
conservation programs or to regulate habitat impacts under State law. 
Federal law and regulations create a legal floor (or minimum 
standards); States may legislate and regulate over and above what 
Federal law or regulations permit.
    Under the ESA's section 6 ``conflict between Federal and State 
laws'' clause, Congress preserved the authority of any state to enact 
and enforce laws or regulations that provide species protections more 
stringent than federal protections while maintaining the ESA's 
preemption over any state law that would permit what is prohibited 
under the ESA or prohibit what is authorized under the ESA (16 U.S.C. 
1535(f)). Where a state lists a species or designates habitat 
protections under a state endangered species law, such as California's 
Endangered Species Act, the state protections will apply to those state 
listed species as long as the state laws do not conflict with the ESA.

[[Page 43311]]

Consequently, species listed under state laws will retain full 
protections under those laws and will remain unaffected by the removal 
of an unnecessary federal regulatory layer of protections. For state 
and local governments, businesses, organizations, and individuals, the 
ESA's cooperative federalism structure provides durable legal security 
for long-term reliance interests that will not be upset by the removal 
of an unnecessary federal ESA regulation. For example, habitat 
mitigation instruments developed to satisfy both federal ESA 
requirements and state law mitigation standards create layered 
contractual and real estate obligations that persist regardless of 
federal ESA regulation. Conservation obligations that run with the land 
or are attached to mitigation instruments will remain enforceable 
against subsequent landowners, thereby preventing disruption to markets 
and organizations that have an interest in ESA protections.
    Nor does this final rule affect the Services' commitment to 
cooperative federalism and coordination with State agencies, which 
takes place pursuant to section 6 cooperative agreements, section 10(a) 
permits, and section 7 consultations, not through the implementation of 
section 9 take prohibitions. For example, section 6 of the ESA permits 
the Secretary of the Interior to ``enter into agreements with any State 
for the administration and management of any area established for the 
conservation of endangered species or threatened species'' (16 U.S.C. 
1535(b)). The Secretary of the Interior may also enter into agreements 
with States, that ``establish[] and maintain[] an adequate and active 
program for the conservation of endangered species and threatened 
species'' and plants (Id. at 1535(c)).\12\ This rule does not change 
any species or critical habitat designations. The Services will 
continue to work with States to support species recovery and habitat 
protection through section 6 cooperative agreements, section 7 
consultations, and other collaborative mechanisms. Moreover, other 
provisions of the ESA such as sections 5 and 7 are specifically 
designed to address habitat conservation will remain unchanged.
---------------------------------------------------------------------------

    \12\ The Services note, again, that the explicit provisions for 
habitat protection in so many other parts of the ESA reinforces its 
conviction that the portion of Section 7 forbidding ``take'' was not 
meant to address habitat modification.
---------------------------------------------------------------------------

    The Services acknowledge that the States have asserted that this 
rulemaking will result in an increased financial and administrative 
burden. However, States continuing to implement laws and policies that 
go beyond that which is required by the ESA is not germane to this 
rulemaking. States may make a policy decision to discontinue 
implementing more stringent species protections in order to relieve 
themselves of this additional burden. Alternatively, states may choose 
to bear the increased costs that go along with their preferred policy 
preferences. The Services, however, reject the invitation to ignore the 
best meaning of the federal statute passed by Congress (and to impose 
increased costs and burdens on other states and individual citizens), 
in order to accommodate the policy preferences of this minority of 
states.
    Comment 17: Commenters emphasize that the rule fails to account for 
impacts to ecosystem services (tangible benefits of natural habitats to 
human communities), existence values (intangible value placed on 
knowing a species or habitat exists), option values (retaining ability 
to use a resource in the future), and the cost of recovery (monetary 
cost of recovering species or habitats). They also state that habitat 
degradation would lead to lost ecosystem services such as pollination, 
water filtration, carbon sequestration, and flood prevention. They 
state that healthy habitats increase recreational opportunities, 
thereby supporting local economies. The commenters argue that these 
effects should be included in the analysis.
    Response: The Services emphasize that the rescission of the 
regulatory definition of ``harm'' does not diminish the importance of 
habitat conservation under the ESA. Habitat-related impacts will be 
addressed under other provisions of the ESA--as was intended--including 
through section 7 consultations and critical habitat designations. The 
Services will continue to use these tools to conserve habitat for 
listed species and as such will continue to address the importance of 
ecosystem services, and other issues raised by the commenters. The 
Services have fulfilled their requirements under State Farm, Department 
of Homeland Security v. Regents, and all other applicable law (see the 
Services' Responses to Comments 13, 15 and 16).
    Comment 18: Some commenters stated that significant public 
investments--Federal, State, local, and Tribal--have been made in 
conservation agreements and habitat management plans that are based the 
long-standing interpretation of ``harm'' under the ESA, which includes 
habitat modification or degradation. A change in this interpretation 
threatens to invalidate or delay these efforts, putting at risk 
financial resources, staff positions, and political commitments. The 
resulting regulatory uncertainty could lead to the discontinuation of 
landowner support programs and a reduction in service levels, 
undermining the current and anticipated infrastructure built to support 
species recovery.
    Commenters stated these investments were designed to meet the needs 
of permittees operating under the current ESA framework. If habitat 
modification is no longer regulated, the market for conservation 
offsets collapses, leaving existing and pending investments stranded. 
This shift would not only jeopardize ongoing recovery efforts critical 
to delisting species and supporting industries like commercial 
fisheries, but it would also erode the economic and environmental 
resilience built through decades of coordinated public and private 
restoration work. The proposed policy change represents a sudden and 
destabilizing departure from decades of consistent ESA implementation. 
Commenters state this change could potentially lead to increased 
habitat destruction, jeopardizing both Tribal and commercial use of 
natural resources. The resulting confusion and regulatory gaps would 
place additional economic burdens on communities that depend on 
sustainable natural resources.
    Response: This comment is incorrect in asserting that habitat 
modification is no longer regulated. This rulemaking does not change 
any species classifications or critical habitat designations. The 
Services will continue to work with States to support species recovery 
and habitat protection through section 6 cooperative agreements, 
section 7 consultations, and other collaborative mechanisms.
    As stated in the response to comment 5, the rescission of the 
regulatory definition of ``harm'' does not eliminate the Services' 
ability to issue ITPs or EOS permits where there is an affirmative 
conduct intentionally directed against a particular animal or animals. 
Additionally, the Services will continue to work with applicants to 
ensure that HCPs and CBAs are developed and permitted to address 
species-specific impacts and that the conservation and mitigation 
measures are commensurate with the ESA's definition of ``take.''
    This revision is prospective only and does not affect permits that 
have been granted as of the date this rule becomes final. That is, no 
conservation agreements and habitat management plans that are in effect 
as of the date of this rule becomes final are affected. As noted above, 
such agreements and plans were but one input among many into the 
ultimate decision whether and how

[[Page 43312]]

to authorize a given action (Cf. Seven Cnty. Infrastructure Coal. v. 
Eagle Cnty., Colorado, 605 U.S. 168, 180 (2025)). Disturbing the 
finality of the overall permitting decision would be highly disruptive 
to settled expectations, as well as immensely time-consuming and 
difficult, in return for at most speculative gains. It would also 
contradict the assurance of repose given to permittees in regulations 
governing HCPs (see 50 CFR 17.22(b)(5), 17.32(b)(5); response to 
Comment 5, above). Going forward, the Services intend to review each 
specific situation and species response to the action to determine 
whether it may or may not constitute ``harm'' to a species pursuant to 
section 3 of the ESA. The Services will continue to work with 
applicants to ensure that HCPs and CBAs are developed and permitted to 
address species-specific impacts and that conservation and mitigation 
measures are commensurate with the ESA's definition of ``take.'' This 
rulemaking does not prohibit willing landowners from implementing 
conservation plans and agreements that are more comprehensive than what 
sections 9 and 10 of the ESA require.
    However, beyond situations in which private persons voluntarily 
wish to purchase such mitigation services or need to purchase them in 
order to comply with other provisions of law, the market for such 
services under ESA sections 9 and 10 is a creation of regulations that, 
in the view of the Services, are not authorized by the Act. Where there 
is no justification in law for imposing the relevant regulation, 
imposing such costs is inherently illegitimate--and pleas to keep them, 
though cast in the form of reliance interests, are essentially 
regulatory rent-seeking. The Services therefore, in accord with 
Regents, has decided that ``reliance interests in benefits [i.e., 
regulatory rents] that it views as unlawful are entitled to no or 
diminished weight'' (591 U.S. at 32).
    Comment 19: Several commenters stated that Tribal activities 
associated with the environment and natural resources are not merely 
economic activities but are a deeply rooted cultural, spiritual, and 
subsistence practice. For example, treaty fishing rights are essential 
to preserving their way of life, with nearly every household 
participating in the fish harvest. Communities rely on salmon and other 
species for food, income, and cultural continuity. Any weakening of ESA 
protections--particularly the definition of ``harm''--would 
significantly threaten Tribal abilities to maintain these practices, 
leading to widespread negative impacts on their economy and social 
fabric.
    Response: The Services acknowledge the sovereign status of Tribal 
Nations and recognize that Tribal stewardship of natural resources is 
deeply rooted in cultural, spiritual, and subsistence traditions that 
are integral to Tribal identity and self-determination. The Services 
also reaffirm their commitment to honoring tribal treaty rights in 
full. However, the requirements imposed by the ESA are separate and 
distinct from treaty rights. When it comes to the ESA, the Services 
acknowledge the significance of the policy interests articulated by the 
tribes, but emphasize that this final rule is a legal correction to 
align the regulatory definition of ``harm'' with the single, best 
reading of the ESA's statutory text. This action does not change any 
species classifications or critical habitat designations and ensures 
that the Services' regulations are legally sound and align with the 
best reading of the ESA. The ESA, properly understood, addresses 
habitat-related impacts through other provisions of the ESA, including 
section 7 consultations and section 5 land acquisition authorities. The 
Services remain committed to meaningful coordination and consultation 
with Tribal Nations to ensure that their voices, knowledge, and 
sovereignty are respected in the conservation and recovery of 
endangered and threatened species.
    Comment 20: Several commenters highlighted the substantial economic 
value of healthy habitats and native species, particularly for outdoor 
recreation, tourism, and biodiversity-dependent industries. They warned 
that weakening protections--such as redefining ``harm'' under the 
Endangered Species Act--could lead to wildlife declines, increased 
extinction risks, and economic losses for communities reliant on 
natural resources. Commenters also criticized the proposed rule as 
misleading, arguing it overlooks the effects to small businesses that 
benefit from strong wildlife protections, such as eco-tourism 
businesses, Tribal communities, research institutions, and conservation 
organizations. They called for a thorough economic impact analysis that 
includes all affected stakeholders, not just development interests.
    Response: The Services disagree that the entities mentioned by the 
commenters should be included in an economic impact analysis because 
they are not directly regulated entities for the purpose of the 
Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.). The businesses 
listed by the commenters are not subject to the requirements of the 
rule and are only indirectly affected. Only directly regulated entities 
are required to be considered under the RFA. The extent to which any 
impacts assessed are not limited to development interests as the 
commenters suggest.
    The Services emphasize that the rescission of the regulatory 
definition of ``harm'' does not diminish the importance of habitat loss 
or degradation as a significant threat to many species listed under the 
ESA. Habitat protection and conservation play a critical role in 
species conservation and recovery efforts. Rather, this rule clarifies 
that ``take'' applies only to actions that cause actual injury or death 
to listed species. Habitat-related impacts are considered and addressed 
under other provisions of the ESA, including section 7 consultations, 
critical habitat designations, section 5 land acquisition authorities, 
and cooperation with willing landowners through voluntary programs. The 
Services will continue to use these tools to address threats to species 
and to help chart the path to recovery and delisting. The rescission of 
the definition of ``harm'' intends to align the implementation of the 
Act with the single, best reading of the statute by removing habitat 
modification or degradation as a form of prohibited ``take.'' This 
rulemaking does not prohibit willing landowners from implementing 
conservation plans and agreements that are more comprehensive than what 
sections 9 and 10 of the ESA require. The Services have fulfilled their 
requirements under State Farm, Department of Homeland Security v. 
Regents, and all other applicable law. See the Services' Responses to 
Comments 13, 15, and 16.
    Comment 21: Commenters emphasized that the existing definition of 
``harm'' has supported the growth of a multi-billion-dollar mitigation 
and restoration industry. They cited investments in ecological 
restoration services, mitigation banking, and conservation offsets, 
warning that rescinding the definition could strand existing 
investments, reduce demand for offsets, and diminish compliance 
options. They argued that such changes would stall new projects, 
eliminate markets built around habitat-based regulation, and weaken 
both environmental outcomes and related economic activity.
    Response: The Services recognize that a restoration and mitigation 
industry has developed under the prior regulatory framework. Commenters 
are correct that changes in regulatory drivers may influence market 
demand

[[Page 43313]]

for certain mitigation efforts focused on habitat conservation that 
were once necessary to obtain an incidental take permit under section 
10 of the ESA. As noted in the preamble, the magnitude of such impacts 
is uncertain and not amenable to reliable quantification. Also, as 
noted above in response to Comment 16, state-law regimes remain in 
place, and, where applicable, will still support this industry. This 
partially mitigates the impact of this rule change on the reliance 
interests addressed by these commenters. However, such markets are 
essentially regulatory rents. The best reading of sections 9 and 10 of 
the Act provide no justification for imposing these costs. As such, 
imposing them is inherently illegitimate--and pleas to keep them, 
though cast in the form of reliance interests, are essentially rent-
seeking. The Services therefore, in accord with Regents, has decided 
that ``reliance interests in benefits [i.e., regulatory rents] that it 
views as unlawful are entitled to no or diminished weight'' (591 U.S. 
at 32).
    The Services note again that this rulemaking does not change the 
regulatory regimes for species recovery and habitat protection through 
section 4 critical habitat designations, section 5 land acquisition 
authorities, section 6 cooperative agreements, section 7 consultations, 
and other collaborative mechanisms.
    In other words, conservation outcomes will continue through other 
legally appropriate mechanisms. Additionally, this rulemaking does not 
prohibit willing landowners from implementing conservation plans and 
agreements that are more comprehensive than what sections 9 and 10 of 
the ESA require.
    This revision is prospective only and does not affect permits that 
have been granted as of the date this rule becomes final. That is, no 
conservation agreements and habitat management plans that are in effect 
as of the date of this rule becomes final are affected.
    By rescinding the regulatory definition of ``harm,'' the Services 
are restoring clarity to the statutory framework by aligning the 
definition of ``take'' with the single, best reading of the statute. 
The Services are not taking this action on the basis of any potential 
economic impacts. The Services have fulfilled their requirements under 
State Farm, Department of Homeland Security v. Regents, and all other 
applicable law. See the Services' Responses to Comments 15 and 16.
    Comment 22: Several commenters stated that reducing habitat 
protections now could increase long-term costs to government and 
taxpayers. They stressed that preventive measures--such as conserving 
intact habitat--are generally more cost-effective than emergency 
interventions or species recovery programs after populations have 
declined. In their view, the proposed rule shifts costs into the future 
by lowering preventive protections today.
    Response: The Services acknowledge the general economic principle 
that preventive action often reduces the need for more expensive 
recovery measures later. Maintaining habitat quality typically requires 
fewer resources than restoring degraded ecosystems or supporting 
species once they are at risk of extinction. While the Services are not 
the sole implementers of habitat protection, we work closely with 
Federal, State, Tribal, local, and private partners to support 
proactive conservation efforts that reduce long-term risks and costs, 
and we remain committed to leveraging these partnerships to achieve 
shared conservation outcomes under the ESA.
    The Services are restoring clarity to the statutory framework by 
aligning the definition of ``take'' with the single, best reading of 
the statute. The Services note that other statutory tools, such as 
section 5 land acquisition and section 7 consultations, remain in place 
to support preventive conservation.
    Comment 23: Commenters stated that the proposed rule lacks any 
quantitative economic analysis. They emphasized that no cost-benefit 
assessment is presented, nor are there empirical estimates of 
compliance savings, industry impacts, or foregone ecological and social 
benefits. They argued that this absence undermines transparency and 
hinders evaluation of trade-offs.
    Response: The Services acknowledge that the proposed rule did not 
include a formal quantitative cost-benefit analysis. The magnitude of 
many potential effects--such as reliance investments-and ecological 
outcomes--is unknown and not amenable to reliable monetization with 
current data. Rescinding the definition of ``harm'' is expected to 
reduce certain regulatory burdens, and the scale of those savings was 
determined to be economically significant. A Regulatory Impact Analysis 
was conducted, and the Services estimated annualized quantified cost 
savings of $361.3 million at a 3 percent discount rate and $521.0 
million at a 7 percent discount rate, reflecting reduced planning, 
negotiation, mitigation, and implementation costs for HCPs. A 
regulatory flexibility analysis is not required if an agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. After conducting both an initial 
regulatory flexibility analysis and a final regulatory flexibility 
analysis, the Services certify that this rule will not have a 
significant economic effect on a substantial number of small entities.
    Comment 24: Multiple commenters argued that the proposed rescission 
of the regulatory definition of ``harm'' raises constitutional concerns 
related to the separation of powers and the faithful execution of laws. 
They emphasized that under Article I of the U.S. Constitution, Congress 
holds the authority to enact statutes such as the ESA, while Article II 
obligates the executive branch to faithfully execute those laws. 
Commenters asserted that removing the definition of ``harm'' does not 
relieve the Services of their duty to enforce the ESA as written by 
Congress, including its provisions for protecting both species and 
their habitats. They expressed concern that the proposed rule appears 
to disregard longstanding statutory interpretations and judicial 
precedent, potentially undermining the legislative intent behind the 
ESA. Some commenters argued that eliminating the definition of ``harm'' 
could weaken key regulatory mechanisms, such as HCPs and section 7 
consultations, thereby reducing the effectiveness of the ESA and 
violating the executive branch's constitutional responsibility. Others 
suggested that the rule may overstep the authority granted to agencies 
under Article II by attempting to reinterpret or narrow statutory terms 
that Congress has already defined. Overall, commenters maintained that 
the Services must uphold their constitutional obligation to implement 
the ESA in a manner consistent with congressional intent and judicial 
interpretation, and that the proposed rule risks disrupting this 
balance of powers.
    Response: The Services' current regulatory definition of harm does 
not accord with the single, best meaning of the text. Implementing the 
text as written by Congress is exactly how the executive branch should 
be respecting separation of powers in this instance. Nothing in Loper 
Bright prohibits the executive branch from reevaluating prior statutory 
interpretations to ensure compliance with the statute's text, and, 
given the opinion's insistence on applying the best meaning of the text 
of a law, it would be shocking if it did so. This rule rescinds the 
regulatory definition of ``harm'' on the grounds that it does not 
reflect the best reading of the statutory text, thereby effectuating 
the executive branch's obligation to

[[Page 43314]]

``take Care that the Laws be faithfully executed'' (U.S. Const. art. 
II, section 3.). This recission is fully consistent with Congress's 
definition of ``take'' in section 3 and with the dissent in Sweet Home. 
We are executing the law as written by Congress by addressing habitat-
related impacts through other provisions of the ESA, including section 
7 consultations and section 5 land acquisition authorities. See our 
response to Comment 20 for the Services' discussion on potential 
impacts to HCPs.
    Comment 25: Several commenters opposed the rescission of the 
regulatory definition of ``harm'' and cited a series of judicial 
decisions-- Palila v. Hawaii Dep't of Land & Nat. Res., 471 F. Supp. 
985 (D. Haw. 1979); Palila v. Hawaii, 639 F.2d 495 (9th Cir. 1981; 
Palila), Sierra Club v. Yeutter, 926 F.2d 429 (5th Cir. 1991; Yeutter), 
Cascadia Wildlands v. Scott Timber Co., 618 F. Supp. 3d 1038 (D. Or. 
2022), aff'd, 105 F.4th 1144 (9th Cir. 2024; Cascadia Wildlands), 
Pacific Rivers Council v. Thomas, 30 F.3d 1050 (9th Cir. 1994; Pacific 
Rivers Council), and Tennessee Valley Authority v. Hill, 437 U.S. 153 
(1978; TVA v. Hill)--as evidence that the ESA has long been interpreted 
to prohibit habitat destruction that impairs essential behavioral 
patterns of listed species. These commenters stated that the courts in 
these cases recognized that habitat modification can constitute a 
prohibited ``take'' under the ESA, and that rescinding the regulatory 
definition of ``harm'' would be inconsistent with this precedent and 
undermine the ESA's conservation mandate.
    Response: We acknowledge the cited decisions. However, these cases 
do not require the continued use of the regulatory definition of 
``harm''.
    To begin, two of these cases do not even address the statutory-
construction question at the heart of this rulemaking. Yeutter mentions 
the word ``harm'' only in the facts section, see 926 F.2d at 433 & n.2, 
while the word ``harm'' does not appear in Pacific Rivers Council at 
all. Three other decisions appear only to apply the regulatory 
definition of ``harm,'' not to answer the question of whether that 
regulatory definition is a correct construction of the statutory text. 
See Cascadia Wildlands, 618 F. Supp. 3d. at 1067 (reciting the 
statutory and regulatory definitions, noting the holding of Sweet Home, 
and applying those definitions); 105 F.4th at 1156-57 (similar); 
Palila, 471 F. Supp. at 995. To the extent the remaining decision--the 
Ninth Circuit's Palila decision--does address the question of whether 
the statutory ``take'' (via ``harm'') correctly includes habitat 
destruction, the analysis is extremely cursory and uses outdated modes 
of analysis: It addresses the merits of this question in one, spare, 
four-sentence paragraph, which relied primarily on ``legislative 
history'' (639 F.2d at 497-98).\13\ The bottom line is that the 
Services do not find these decisions persuasive.
---------------------------------------------------------------------------

    \13\ That the named plaintiff in Palila is a species of bird 
also indicates to the Services that its mode of jurisprudence would 
not accord with best modern practices.
---------------------------------------------------------------------------

    Turning to the two Supreme Court cases cited, TVA v. Hill is not on 
point. Its reflections on legislative history and Congressional purpose 
are interesting, and taken by the Services for what they are worth. But 
Hill does not address or answer the statutory-interpretation question 
at answer in this rulemaking. The case that does is Sweet Home. The 
majority's holding in that case, applying Chevron, is that the 
construction then proffered by the Services was ``reasonable.'' For the 
reasons explained pervasively in this final rule and in the proposed 
rule, the Services are persuaded instead by Justice Scalia's analysis 
as to what the correct construction of the statutory text is.
    We recognize that the Supreme Court held in Loper Bright that its 
``prior cases that relied on the Chevron framework . . . are still 
subject to statutory stare decisis'' (603 U.S. at 412). But under the 
then-prevailing Chevron framework, Sweet Home held only that the 
existing regulation is a permissible reading of the ESA, not the only 
possible such reading. Our rescission of the regulatory definition on 
the grounds that it does not reflect the best reading of the statutory 
text thus is fully consistent with Sweet Home.
    Accordingly, while these decisions illustrate how the prior 
regulatory definition of ``harm'' was applied in specific factual 
contexts, they did not determine that the regulatory definition of harm 
constituted the single best reading of the ESA and thus do not preclude 
the Services from rescinding that definition in favor of a reading that 
better aligns with the statutory text.
    Comment 26: Some commenters cited Skidmore v. Swift & Co., 323 U.S. 
134 (1944; Skidmore), and Kimble v. Marvel Entertainment, LLC, 576 U.S. 
446 (2015; Kimble), to argue that the Services should retain the 
regulatory definition of ``harm'' out of respect for longstanding 
agency interpretations and the principle of stare decisis. These 
commenters contended that even if Chevron deference no longer applies, 
the Services' decades-long interpretation of ``harm'' should still be 
afforded weight under Skidmore, and that the principle of stare 
decisis, as reaffirmed in Kimble, counsels against rescinding a settled 
regulatory interpretation absent a compelling justification.
    Response: The Services recognize the importance of consistency and 
stability in interpretation of the ESA; however, neither case compels 
the retention of the regulatory definition of ``harm,'' which runs 
contrary to the text and structure of the ESA.
    Under Skidmore, agency interpretations may be entitled to respect 
by courts to the extent they have the ``power to persuade.'' It is 
true, furthermore, that courts have opined that ``respect'' has been 
``especially warranted when an Executive Branch interpretation was 
issued roughly contemporaneously with enactment of the statute and 
remained consistent over time'' (Loper Bright, 603 U.S. at 386). 
```Respect,' though, was just that'' (Id.). A court should never afford 
respect to an agency interpretation--under Skidmore or any other 
precedent--when that interpretation runs contrary to the text and 
structure of the statutory language, as Justice Scalia's Sweet Home 
dissent observed. In this rulemaking, the Services have determined that 
the prior regulatory definition of ``harm'' does not reflect the best 
meaning of the statutory text. Moreover, the Services are, to begin, 
not a court, and thus Skidmore deference is arguably inapposite.
    As for Kimble, it is inapt, because it addresses the considerations 
that courts must consider when repudiating their own prior precedents 
regarding how to interpret a statute, i.e., what the best reading of 
the statute is. By contrast, the idea of applying stare decisis to 
agency action is inconsistent with a core tenet of administrative law: 
agencies may change positions. See, e.g., FDA v. Wages & White Lion 
Investments, L.L.C., 604 U.S. 542, 569-70 (2025). In other words, there 
is no such thing as stare decisis for agency interpretation. Agencies 
are permitted to revise or rescind prior interpretations when warranted 
by changes in law, policy, or interpretive standards.
    Accordingly, while the Services respect the values of consistency 
and institutional experience, those values do not override the 
obligation to interpret the ESA in accordance with its best reading.

Required Determinations

Regulatory Planning and Review--Executive Orders 12866 and 13563

    Executive Order (E.O.) 12866 provides that the Office of 
Information and Regulatory Affairs (OIRA) in the Office

[[Page 43315]]

of Management and Budget will review all significant rules. OIRA has 
determined that this rule is 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 final rule in a manner 
consistent with these requirements.

Unleashing Prosperity Through Deregulation--E.O. 14192

    This final rule is an E.O. 14192 deregulatory action.

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

    Under the Regulatory Flexibility Act (RFA), 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. We certify that this 
rule will not have a significant economic impact on a substantial 
number of small entities. The following discussion explains our 
rationale.
    This final rule is deregulatory and is generally expected to 
benefit small entities regulated by the ESA, primarily those entities 
that voluntarily seek and are subsequently issued section 10(a) 
permits. To the extent that fewer future ESA section 10(a) permits are 
issued, lower administrative and recordkeeping costs are likely. 
Additionally, to the extent that future permits are not issued or are 
issued in a more limited capacity, some portion of otherwise-affected 
small entities would benefit by avoiding implementation costs. 
Furthermore, dependent on the extent to which a reduced number of 
section 10(a) permits are issued, a reduction in activities on the part 
of entities engaged in restoration and habitat protection activities 
could result. However, we do not expect this potential effect to rise 
to the level of a significant economic effect nor affect a substantial 
number of small entities. Therefore, we certify that this rule will 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 presented under Regulatory 
Flexibility Act, above, this rule will not ``significantly or 
uniquely'' affect small governments. We have determined and certify 
pursuant to the Unfunded Mandates Reform Act that this final rule will 
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 will not be 
affected because the final rule will not place additional requirements 
on any city, county, or other local municipalities.
    (b) This rule will 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 final rule is not a ``significant regulatory 
action'' under the Unfunded Mandates Reform Act. This final rule will 
impose no obligations on State, local, or Tribal governments.

Takings--E.O. 12630

    In accordance with E.O. 12630, this rule will not have significant 
takings implications. This rule does not pertain to ``taking'' of 
private property interests, nor will it directly affect private 
property. A takings implication assessment is not required because this 
final rule (1) will not effectively compel a property owner to suffer a 
physical invasion of property and (2) will not deny all economically 
beneficial or productive use of the land or aquatic resources. This 
rule substantially advances a legitimate government interest 
(eliminating regulatory definitions that do not align with the best 
meaning of the ESA) and will not present a barrier to all reasonable 
and expected beneficial use of private property.

Federalism--E.O. 13132

    In accordance with E.O. 13132, we have considered whether this rule 
will have significant federalism effects and have determined that a 
federalism summary impact statement is not required. This rule rescinds 
the regulatory definition of ``harm'' and will not have substantial 
direct effects on the States, on the relationship between the Federal 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.

Civil Justice Reform--E.O. 12988

    This final rule does not unduly burden the judicial system and 
meets the applicable standards provided in sections 3(a) and 3(b)(2) of 
E.O. 12988. This final rule rescinds the regulatory definition of 
``harm''.

Government-to-Government Relationship With Tribes--E.O. 13175

    In accordance with the President's memorandum of April 29, 1994 
(``Government-to-Government Relations With Native American Tribal 
Governments;'' 59 FR 22951, May 4, 1994), E.O. 13175 (``Consultation 
and Coordination with Indian Tribal Governments''), the President's 
memorandum of November 30, 2022 (``Uniform Standards for Tribal 
Consultation;'' 87 FR 74479, December 5, 2022), and the Department of 
the Interior's manual at 512 DM 2, and the National Oceanic and 
Atmospheric Administration (NOAA) Administrative Order (NAO) 218-8 
(April 2012), we considered the possible effects of this rule on 
federally recognized Tribes. After the opening of the public comment 
period, we received multiple requests for coordination or Government-
to-Government consultation from multiple Tribes: Cheyenne River Sioux 
Tribe, Great Lakes Indian Fish and Wildlife Commission, Pueblo of San 
Felipe, Fond du Lac Band of Lake Superior Chippewa, Swinomish Indian 
Tribal Community, Fallon Paiute Shoshone Tribe, Lower Elwha Klallam 
Tribe, Quinault Indian Nation, Confederated Tribes and Bands of the 
Yakama Nation, Cowlitz Indian Tribe, and Bishop Paiute Tribe.
    The Service concludes that this rule is general in nature and does 
not directly affect any specific Tribal lands, treaty rights, or Tribal 
trust resources. This

[[Page 43316]]

regulation, which removes the definition of ``harm'' from 50 CFR 17 and 
222, does not have direct, substantial effects on one or more Indian 
Tribes, as the Services issue permits to Indian Tribes on a very 
limited basis, but rather consult and coordinate with Tribes on a case-
by-case basis. This rule is general in nature and does not directly 
affect any specific species, Tribal lands, treaty rights, or Tribal 
trust resources. Therefore, we conclude that this regulation does not 
have ``tribal implications'' under section 1(a) of E.O. 13175 and 
formal government-to-government consultation is not required by E.O. 
13175 and related policies of the Department of the Interior and the 
Department of Commerce. We will continue to collaborate with Tribes on 
issues related to federally listed species and work with them as we 
implement the provisions of the Act. See Joint Secretary's Order 3206 
(``American Indian Tribal Rights, Federal-Tribal Trust 
Responsibilities, and the Endangered Species Act,'' June 5, 1997).

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

    This final 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 (42 U.S.C. 4321 et seq.)

    We have analyzed this rule in accordance with the National 
Environmental Policy Act (NEPA, 42 U.S.C. 4321 et seq.), the Department 
of the Interior National Environmental Policy Act implementing 
regulations at 43 CFR part 46, the Department of the Interior Handbook 
of National Environmental Policy Act Implementing Procedures (516 DM 
1), the NOAA Administrative Order 216-6A, and the NOAA Companion Manual 
(CM), ``Policy and Procedures for Compliance with the National 
Environmental Policy Act and Related Authorities'' (effective June 30, 
2025).
    The Services have determined that the ``proposed agency action is a 
nondiscretionary action with respect to which such agency does not have 
authority to take environmental factors into consideration in 
determining whether to take the proposed action'' (42 U.S.C. 
4336(a)(4); see Dep't of Transp. v. Pub. Citizen, 541 U.S. 752, 766-70 
(2004)).
    The Services have also determined, in the alternative, that there 
will be no significant individual or cumulative effect on the quality 
of the human environment with the rescission of the definition of 
``harm'' in 50 CFR part 17.3 and have applied a categorical exclusion 
to comply with the NEPA, specifically, the Department of the Interior 
categorical exclusion for ``Policies, directives, regulations, and 
guidelines: that are of an administrative, financial, legal, technical, 
or procedural nature; or whose environmental effects are too broad, 
speculative, or conjectural to lend themselves to meaningful analysis 
and will later be subject to the NEPA process, either collectively or 
case-by-case'' (43 CFR 46.210(i)), which NOAA has adopted, consistent 
with NOAA's NEPA procedures (NOAA CM V(F)). We have also determined the 
extraordinary circumstances listed in 43 CFR 46.215 do not apply to the 
direct effects of the proposed action.
    We completed an environmental action statement for the categorical 
exclusion for the rescission of the definition of ``harm'' in 50 CFR 
part 17.3. The environmental action statement and supporting 
categorical exclusion documentation is available at https://www.regulations.gov in Docket No. FWS-HQ-ES-2025-0034.

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

    E.O. 13211 (Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use) requires agencies to 
prepare statements of energy effects ``to the extent permitted by law'' 
when undertaking actions identified as significant energy actions (66 
FR 28355; May 22, 2001). E.O. 13211 defines a ``significant energy 
action'' as an action that (i) is a significant regulatory action under 
E.O. 12866 (or any successor order); and (ii) is likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy. This final rule is not expected to affect energy supplies, 
distribution, and use. Therefore, this action is not a significant 
energy action, and there is no requirement to prepare a statement of 
energy effects for this action.

Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.)

    In finalizing this rule, the Services are acting in their unique 
statutory role as administrators of the Act and are engaged in a legal 
exercise of interpreting the standards of the Act. The Services' 
administration of the Act is not in itself subject to the Act's 
provisions, including section 7(a)(2). The Services have a historical 
practice of issuing their general regulations under the ESA without 
undertaking section 7 consultation. This practice accords with the 
plain language, structure, and purposes of the ESA, which does not 
place a consultation obligation on the Services' administration of the 
Act. Although the Services consult on actions through intra-agency 
consultations where appropriate (e.g., issuance of permits under 
section 10(a) and actions under statutory authorities other than the 
ESA), the Services in those instances are acting principally as an 
``action agency'' carrying out provisions of the Act or other statutes. 
Here, by contrast, the Services are acting solely in their role as 
administrators of the ESA; we are also not administering the Act to 
propose or take a specific action. The Services are carrying out the 
most fundamental exercise of our role as administrators of the ESA, and 
the Act cannot reasonably be construed as requiring the Services to 
``consult'' with themselves under section 7(a)(2) in such cases.
