Abstract

The Department of the Interior (Department or DOI) is partially rescinding and making necessary targeted updates to its remaining regulations implementing the National Environmental Policy Act (NEPA), which were promulgated to "supplement" now-rescinded Council on Environmental Quality (CEQ) NEPA implementing regulations. Mindful that the Supreme Court recently clarified NEPA is a "purely procedural statute," DOI will henceforth maintain the remainder of its NEPA procedures--which apply only to DOI's internal processes--in a Handbook separate from the Code of Federal Regulations (CFR). This interim final rule requests comments on this action and related matters to inform DOI's decision-making.

SUPPLEMENTARY INFORMATION:

I. Background

    DOI is issuing this interim final rule to partially rescind and 
make other needed, targeted updates to its regulations for 
implementation of the National Environmental Policy Act of 1969, 42 
U.S.C. 4321 et seq., as amended (NEPA), codified at 43 CFR part 46. 
DOI's existing NEPA implementing regulations were promulgated as a 
``supplement. . . to be used in conjunction with,'' 43 CFR 46.20, CEQ's 
NEPA regulations. DOI provided that the ``[p]urpose of this part'' was 
to ensure ``compliance with'' not only NEPA itself but CEQ's 
regulations implementing NEPA. 43 CFR 46.10(a)(2). But CEQ's NEPA 
regulations have been repealed, as of April 11, 2025. See Removal of 
National Environmental Policy Act Implementing Regulations, (90 FR 
10610; Feb. 25, 2025). CEQ's repeal of its regulations was necessitated 
by and is consistent with Executive Order (E.O.) 14154, Unleashing 
American Energy (90 FR 8353; January 29, 2025), in which President 
Trump rescinded President Carter's E.O. 11991, Relating to Protection 
and Enhancement of Environmental Quality (42 FR 26967; May 24, 1977), 
which was the basis CEQ had invoked for its authority to make rules. 
President Trump in E.O. 14154 further directed agencies to revise their 
NEPA implementing procedures consistent with the E.O., including its 
direction to CEQ to rescind its regulations. DOI's regulations, which 
were a ``supplement . . . to be used in conjunction with'' those CEQ 
regulations, thus stand in obvious need of fundamental revision.
    In addition, Congress recently passed the Fiscal Responsibility Act 
of 2023 (FRA), Public Law 118-5, signed on June 3, 2023 to add 
substantial detail and direction in Title I of NEPA, including in 
particular on procedural issues that CEQ, DOI, and other agencies had 
previously addressed in their own regulations. DOI recognized the need 
to update its regulations in light of these significant statutory 
changes. Since DOI's regulations were originally designed to supplement 
CEQ's NEPA regulations, DOI had been awaiting CEQ action before 
revising its own regulations, consistent with CEQ direction. See 40 CFR 
1507.3(b) (2024); see also 86 FR 34154 (June 29, 2021). However, now 
that CEQ's regulations have been repealed, it is exigent that DOI 
ensure procedures conform to the statute as amended by the FRA.
    Finally, the Supreme Court has recently issued its decision in 
Seven County Infrastructure Coalition v. Eagle County, Colorado, 145 S. 
Ct. 1497 (2025), in which it described the ``transform[ation]'' of NEPA 
from its roots as ``a modest procedural requirement,'' into a 
significant ``substantive roadblock'' that ``paralyze[s]'' ``agency 
decisionmaking.'' Id. at 1507, 1513 (quotations omitted). The Supreme 
Court explained that part of that problem had been caused by decisions 
of lower courts, which it rejected, issuing a ``course correction'' 
mandating that courts give ``substantial deference'' to reasonable 
agency conclusions underlying that agency's NEPA process. Id. at 1513-
14. The Court also acknowledged, and through its course correction 
sought to address, the effect judicial ``micromanage[ment]'' has had on 
``litigation-averse agencies'' which have been ``tak[ing] ever more 
time and . . . [prepar[ing] ever longer EISs [environmental impact 
statements] for future projects.'' Id. at 1513. DOI, thus, is issuing 
this IFR to streamline its NEPA process in accordance with the Supreme 
Court's decision and changes to the underlying statute. This revision 
has thus been called for, authorized, and directed by all three 
branches of government at the highest possible levels.
    NEPA does not require Federal agencies to issue regulations 
implementing NEPA, but instead directs agencies to ``identify and 
develop methods and procedures,'' in coordination with CEQ, with 
respect to their environmental analysis of their proposed actions, see 
42 U.S.C. 4332(2)(B). Both E.O. 14154 and E.O. 14192 direct agencies to 
ensure regulatory requirements are grounded in applicable law and to 
alleviate any unnecessary regulatory burdens, respectively. Consistent 
with the direction in these E.O.s to reduce unnecessary regulatory 
burdens, DOI will rescind portions of its NEPA

[[Page 29499]]

implementing regulations at 43 CFR part 46, while retaining and making 
targeted updates to certain provisions. Specifically, DOI intends to 
retain and make limited updates to provisions relating to emergency 
responses to ensure that DOI can respond timely to any such event and 
to avoid any confusion regarding the continued validity of this 
already-established provision for action in emergency situations (43 
CFR 46.150); categorical exclusions and their use to avoid any 
instability in these vital procedures or uncertainty about the 
continued validity of its already-established categorical exclusions 
(43 CFR 46.205, 46.210, 46.215); and applicant and contractor 
preparation of environmental documents to provide a durable framework 
for the use of such documents (43 CFR 46.105, 46.107). All other 
provisions will be removed from 43 CFR part 46. Other than these few 
provisions, DOI's procedures will henceforth be contained in the 
Department of the Interior Handbook: National Environmental Policy Act 
Implementing Procedures, a copy of which is available in the docket 
listed under ADDRESSES above (but will not be codified in the CFR).
    The Supreme Court could not have been clearer in Seven County that 
NEPA is a procedural statute. See Seven County, 145 S. Ct. at 1510 
(``NEPA is purely procedural. . . . NEPA does not mandate particular 
results, but simply prescribes the necessary process for an agency's 
environmental review of a project;'') (internal quotation omitted); id. 
at 1511 (NEPA is a purely procedural statute''); id. at 1513 (NEPA is 
properly understood as ``a modest procedural requirement''); id. at 
1514 (``NEPA's status as a purely procedural statute''); see also id. 
at 1507 (``Simply stated, NEPA is a procedural cross-check, not a 
substantive roadblock.''). The history of DOI's implementing 
regulations also reflects the understanding that they are procedural 
rules, for they were uncodified for over a decade before being codified 
``as a matter of good policy.'' This is, moreover, consistent with the 
approach that several other Federal agencies have used for decades.
    This action fulfills President Trump's directive in E.O. 14154 for 
each agency to, in consultation with CEQ, revise its agency-level NEPA 
implementing procedures in light of the FRA. 90 CFR at 8355. This 
action implements E.O. 14154 and complies with the requirements of the 
Administrative Procedure Act (APA). DOI requests comment on the 
rescission of portions of its regulations implementing NEPA and its 
retention and targeted updates to its remaining regulations 
implementing NEPA, as well as the Department of the Interior Handbook: 
National Environmental Policy Act Implementing Procedures, a copy of 
which is available in the docket listed under ADDRESSES above (but will 
not be codified in the CFR). This notice serves to provide fair notice 
to interested persons and to allow for public comment on DOI's interim 
final rulemaking. Public comments on the matters addressed in this 
interim final rule are due by August 4, 2025. As explained in Section 
IV of this notice, DOI requests and encourages public comment on the 
rationale for this action and related matters that may inform DOI's 
decision making.

A. National Environmental Policy Act

    Congress enacted NEPA to declare a national policy ``to use all 
practicable means and measures, including financial and technical 
assistance, in a manner calculated to foster and promote the general 
welfare, to create and maintain conditions under which man and nature 
can exist in productive harmony, and [to] fulfill the social, economic, 
and other requirements of present and future generations of 
Americans.'' 42 U.S.C. 4331(a).
    NEPA, as amended by the FRA, furthers this national policy by 
requiring Federal agencies to prepare an environmental impact 
statement--``in essence, a report''--for proposed ``major Federal 
actions significantly affecting the quality of the human environment.'' 
42 U.S.C. 4332(2)(C); Seven County, 145 S. Ct. at 1507. This statement 
must address: (1) The reasonably foreseeable environmental effects of 
the proposed agency action; (2) the reasonably foreseeable adverse 
environmental effects that cannot be avoided; (3) a reasonable range of 
alternatives to the proposed agency action, including an analysis of 
any negative environmental impacts of not implementing the proposed 
agency action in the case of a no action alternative, that are 
technically and economically feasible, and meet the purpose and need of 
the proposal; (4) the relationship between local short-term uses of 
man's environment and the maintenance and enhancement of long-term 
productivity; and (5) any irreversible and irretrievable commitments of 
resources that would be involved in the proposed action. 42 U.S.C. 
4332(2)(C).
    NEPA further mandates that Federal agencies ensure the professional 
and scientific integrity of environmental documents; use reliable data 
and resources when carrying out NEPA; and study, develop, and describe 
technically and economically feasible alternatives. 42 U.S.C. 
4332(2)(D)-(F). NEPA provides procedures for making threshold 
determinations about whether an environmental document must be prepared 
and the appropriate level of environmental review. 42 U.S.C. 4336(a)-
(b).
    NEPA does not mandate specific results or substantive outcomes. 
Seven County, 145 S. Ct. at 1507. Rather, NEPA requires Federal 
agencies to consider the environmental effects of proposed actions as 
part of agencies' decision-making processes. As amended by the FRA, 
NEPA provides additional requirements to facilitate timely and unified 
Federal reviews, including provisions clarifying lead, joint lead, and 
cooperating agency designations, generally requiring the development of 
a single environmental document, directing agencies to develop 
procedures for project sponsors to prepare environmental assessments 
and environmental impact statements, and prescribing page limits and 
deadlines. 42 U.S.C. 4336a. NEPA also sets forth the circumstances 
under which agencies may rely on programmatic environmental documents, 
42 U.S.C. 4663b, and adopt and use another agency's categorical 
exclusions. 42 U.S.C. 4336c.

B. NEPA Regulations

1. Council on Environmental Quality (CEQ) NEPA Regulations
    On January 20, 2025, President Trump issued E.O. 14154, Unleashing 
American Energy.\1\ The E. O. revoked E.O. 11991, Relating to 
protection and enhancement of environmental quality,\2\ which had 
directed CEQ to issue regulations implementing NEPA and required 
Federal agencies to comply with those regulations.\3\ E.O. 14154 also 
directed CEQ to provide guidance on implementing NEPA and propose 
rescinding CEQ's NEPA regulations within 30 days of the order.\4\ CEQ 
issued an interim final rule rescinding CEQ's NEPA implementing 
regulations (including as they relate to agency NEPA procedures) on 
February 25, 2025, effective April 11, 2025.\5\ Following CEQ's 
provision of initial guidance, E.O. 14154 directs the Chairman of CEQ 
to convene a working group to coordinate the revision of

agency-level NEPA implementing regulations for consistency.

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

2. DOI NEPA Regulations
    Until 2008, DOI provided procedures for implementing NEPA in 
chapters of part 516 of the Department Manual. DOI periodically revised 
the Department Manual chapters containing NEPA procedures through a 
notice and comment process that involved publication of proposed and 
final revisions in the Federal Register, but did not promulgate as 
regulations the procedures contained in the Department Manual. In 2008, 
DOI promulgated regulations codifying DOI's NEPA procedures at 43 CFR 
part 46. In the preamble to the 2008 notice of proposed rulemaking,\6\ 
DOI explained that ``[t]he Department believes that codifying the 
procedures in regulations that are consistent with NEPA and the CEQ 
regulations will provide greater visibility to that which was 
previously contained in the [Department Manual] DM and enhance 
cooperative conservation by highlighting opportunities for public 
engagement and input in the NEPA process.'' 73 FR 61292. DOI retained 
additional explanatory guidance (as distinguished from agency 
implementing procedures) in the Department Manual and other 
Departmental guidance documents. Bureaus and offices (bureaus) of the 
Department continue to maintain Department Manual chapters in part 516 
specific to their programs which supplement the DOI NEPA implementing 
procedures.
---------------------------------------------------------------------------

    \6\ 73 FR 126 (Jan. 2, 2008).
---------------------------------------------------------------------------

    E.O. 14154 directs all agencies to prioritize efficiency and 
certainty over any other objectives and avoid and minimize delays and 
ambiguity in the permitting process. DOI's internal procedures and 
policies to guide compliance with NEPA will better advance the 
priorities articulated in E.O. 14154 and provide for quicker updates in 
policy implementation for bureaus to use than will retaining the NEPA 
implementing regulations. Consolidating procedures with many other 
policies and guidance will also provide additional public transparency.
    Moreover, DOI has decided that the flexibility to respond to new 
developments in this fast-evolving area of law, afforded by using non-
codified procedures, outweighs the appeal of maintaining its NEPA 
procedures as regulations going forward. Notably, in this digitized 
age, while DOI codified its procedures as regulations, in part, to 
provide ``greater visibility'' to the public, DOI can--and will--ensure 
such visibility simply by posting these procedures online, which 
removes the upside of codification. By contrast, not maintaining its 
procedures as regulations will enable it to rapidly update these 
procedures in response to future court decisions (such as Seven County) 
or Presidential directives (such as E.O. 14154). The balance thus tips 
decisively toward using a non-regulatory, but publicly accessible, 
procedural document. Because rescinding DOI's existing regulations 
without simultaneously adopting a replacement would likely cause 
uncertainty among regulated parties, the new procedures that DOI adopts 
today have informed its decision to rescind most of its prior 
regulations.
    DOI's new NEPA implementing procedures are a more faithful 
implementation of the statute as amended in 2023 than its old 
procedures. They implement major structural features of the 2023 
amendments, such as deadlines and page limits for environmental 
assessments and environmental impact statements, as directed at NEPA 
Section 107(g), and provide that DOI will complete preparation of these 
documents within the maximum length and on the timeline that Congress 
intends. They incorporate Congress's definition of ``major Federal 
action'' and the exclusions thereto, as codified at NEPA Section 
111(10). They incorporate Congress's mandated procedure for determining 
the appropriate level of review under NEPA, as codified in NEPA Section 
106. And they incorporate Congress's revision to the requirements for 
what an agency must address in its environmental impact statements, as 
codified at NEPA Section 102(2)(C), and Congress's requirement that 
public notice and solicitation of comment be provided when issuing a 
notice of intent to prepare an environmental impact statement, as 
directed at NEPA Section 107(c). All of these are crucial features of 
Congress's policy design and its purpose in the 2023 amendments that 
NEPA review be more efficient and certain.
    Moreover, all of these respond to the President's directive in E.O. 
14154; and all of these reflect the Supreme Court's recent and 
unequivocal statement that NEPA is a purely procedural statute. DOI is 
conscious of the Supreme Court's admonition that NEPA review has grown 
out of all proportion to its origins as a ``modest procedural 
requirement,'' creating, ``under the guise of just a little more 
process,'' ``[d]elay upon delay, so much so that the process seems to 
`borde[r] on the Kafkaesque.' '' Seven County, 145 S. Ct. at 1513-14 
(internal quotation omitted). These procedures, therefore, attempt to 
align NEPA with its Congressionally mandated dimensions, reflecting the 
guidance given also by the President and the Supreme Court, and making 
review under it faster, more flexible, and more efficient.
    In reaching this decision, DOI acknowledges that third parties may 
claim to have reliance interests in DOI's existing NEPA procedures. But 
revised agency procedures will have no effect on ongoing NEPA reviews, 
where DOI, following CEQ guidance, will continue to apply the 
preexisting procedures to applications that are sufficiently advanced. 
Moreover, as the Supreme Court has just explained, NEPA ``is a purely 
procedural statute'' that ``imposes no substantive environmental 
obligations or restrictions.'' Seven County, 145 S. Ct. at 1507. To the 
extent any asserted reliance interests are grounded in substantive 
environmental concerns, such interests are entitled to ``no. . . 
weight.'' Dep't of Homeland Sec. v. Regents of the Univ. of California, 
140 S. Ct. 1891, 1914 (2020).
    Because reliance interests are inherently backward-looking, it is 
unclear how any party could assert reliance interests in prospective 
procedures. To the extent such interests exist, the Department holds 
that they are ``outweigh[ed]'' by ``other interests and policy 
concerns.'' Id. Namely, the complex web of regulations that preexisted 
the 2023 amendments to NEPA and these new procedures repeatedly ``led 
to more agency analysis of separate projects, more consideration of 
attenuated effects, more exploration of alternatives to proposed agency 
action, more speculation and consultation and estimation and 
litigation,'' which in turn has meant that ``[f]ewer projects make it 
to the finish line,'' or even ``to the starting line.'' Seven County, 
145 S. Ct. at 1513-14. This has increased the cost of projects 
dramatically, ``both for the agency preparing the EIS and for the 
builder of the project,'' resulting in systemic harms to America's 
infrastructure and economy. Id. Correspondingly, the wholesale revision 
and simplification of this regime, effectuated by the revision of DOI's 
NEPA procedures and relocation of them to the Department of the 
Interior Handbook: National Environmental Policy Act Implementing 
Procedures, is necessary to ensure efficient and predictable reviews, 
with significant upsides for the economy and for projects of all sorts. 
This set of policy considerations drastically outweighs any claimed 
reliance interests in the preexisting procedures.

[[Page 29501]]

    DOI has revised its NEPA implementing procedures to conform to the 
2023 statutory amendments, to respond to President Trump's direction in 
E.O. 14154, and to address the pathologies of the NEPA process and NEPA 
litigation identified by the Supreme Court.
    Where DOI has retained an aspect of its preexisting NEPA 
implementing procedures, it is because that aspect is compatible with 
these guiding principles; where DOI has revised or removed an aspect, 
it is because that aspect is not compatible.

II. Discussion of Regulatory Changes

A. Removing NEPA Procedures From Regulation

    NEPA requires that all Federal agencies identify and develop 
methods and procedures, in consultation with CEQ, that will ensure that 
unquantified environmental amenities and values may be given 
appropriate consideration in decision-making along with economic and 
technical considerations. 42 U.S.C. 4332(2)(B). The statutory 
amendments to NEPA under the FRA also refer to agency NEPA 
procedures.\7\ Federal agencies have developed varying forms of NEPA 
implementing procedures, some in regulation and some in other forms of 
procedural documents. DOI's revised NEPA procedures, developed in 
consultation with CEQ and in coordination with other Federal agencies 
for consistency across the Federal government, will facilitate 
compliance with the statutory obligations of NEPA.
---------------------------------------------------------------------------

    \7\ 42 U.S.C. 4336a(f), 4336c.
---------------------------------------------------------------------------

B. Retaining and Revising Certain Provisions

    The rule removes most of the existing DOI NEPA regulations in favor 
of relying on Departmental guidance for the reasons discussed above, 
but the rule retains and makes targeted updates to its regulations that 
authorize three tools that DOI bureaus may rely on to expedite NEPA 
reviews and ensure that compliance with NEPA is achieved in an 
efficient manner.
1. Emergency Responses
    First, DOI is retaining 43 CFR 46.150, which allows bureaus to 
respond to emergencies while either forgoing NEPA analysis so as to 
allow the bureau to take actions ``urgently needed to mitigate harm to 
life, property, or important natural, cultural, or historic resources'' 
and use alternative arrangements for NEPA compliance to take other 
actions beyond those immediately necessary to protect life, property, 
and resources in response to emergencies. The rule makes minor 
clarifying adjustments to the text that reflect DOI's experience 
implementing these provisions. The adjustments do not change the 
meaning of the provisions.\8\
---------------------------------------------------------------------------

    \8\ Executive Order 14156, Declaring a National Energy Emergency 
(Jan. 20, 2025); Secretary's Order 3417, Addressing the National 
Energy Emergency (Feb. 3, 2025).
---------------------------------------------------------------------------

2. Categorical Exclusions
    Next, DOI is retaining 43 CFR 46.205, 46.210, and 46.215, which 
establish Departmental categorical exclusions and lay out the 
procedures for relying on a categorical exclusion to comply with NEPA. 
Categorical exclusions represent those categories of actions that DOI 
has determined normally do not significantly affect the environment. 
Categorical exclusions provide important efficiency by ensuring that 
many agency actions are not subjected to the lengthy NEPA process and 
can proceed using the significantly truncated process identified in the 
DOI NEPA regulations for determining that a categorical exclusion 
applies and ensuring that no ``extraordinary circumstances'' are 
present that would preclude reliance on the categorical exclusion. 
Section 46.210 will continue to identify Departmental categorical 
exclusions while additional, bureau-specific categorical exclusions are 
identified in guidance documents.
    Although DOI is largely retaining these provisions in regulation, 
the rule revises them to eliminate from the regulations certain 
categorical exclusions that are not used across the Department and to 
refine certain other extraordinary circumstances that, when present, 
would preclude reliance on a categorical exclusion. Section 46.205 
includes new paragraphs (e), (f), (g), (h), (i), and (j) providing how 
DOI bureaus may rely on categorical exclusion determinations made by 
other agencies, may apply multiple categorical exclusions to a single 
action, and may rely on a categorical exclusion administratively 
established or adopted by another DOI bureau; the procedures governing 
the establishment, modification, or removal of categorical exclusions 
from NEPA procedures; and the clarification that any such 
establishment, modification, or removal does not itself have any 
environmental effects for purposes of NEPA. In Section 46.210, the rule 
removes paragraphs (k) and (l), which describe categorical exclusions 
for hazardous fuels reduction activities using prescribed fire and 
post-fire rehabilitation activities, respectively. These categorical 
exclusions will continue to be identified in bureau-specific NEPA 
procedures, and those bureaus may then continue to rely on them for 
purposes of NEPA compliance, but they are not properly considered 
Departmental categorical exclusions.
    In Section 46.215, which lists the ``extraordinary circumstances'' 
that, if present preclude reliance on a categorical exclusion, the rule 
removes existing paragraphs (c), (i), and (j), and then renumbers the 
remaining paragraphs. Paragraph (c) provides that an extraordinary 
circumstance is present if an action may ``[h]ave highly controversial 
environmental effects or involve unresolved conflicts concerning 
alternative uses of available resources.'' 43 CFR 46.215(c). This 
provision causes confusion as it has been frequently misunderstood to 
mean that any controversy surrounding the substance of the action 
itself constitutes an extraordinary circumstance. The provision is 
intended only to provide that controversy about the nature and 
magnitude of the environmental effects of the action constitutes an 
extraordinary circumstance. In any event, the concept is sufficiently 
addressed in existing paragraph (d) (which this rule renumbers as 
paragraph (c)).
    Paragraph (i) provides that an extraordinary circumstance is 
present if an action may ``[v]iolate a Federal law, or a State, local, 
or tribal law or requirement imposed for the protection of the 
environment.'' 43 CFR 46.215(i). Whether a proposed Federal action may 
violate a law imposed for the protection of the environment is a 
question that goes beyond the procedural requirements of NEPA and may 
be better considered and appropriately addressed by the Responsible 
Officer when making the decision on the proposed action. While a 
proposed action's inconsistency with such a law should be appropriately 
considered in the agency decision-making process--and may suggest that 
that the proposed action should not be approved--it is not relevant to 
the determination of whether the proposed action may have significant 
environmental effects.
    Paragraph (j) was promulgated in response to E.O. 12898, Federal 
Actions To Address Environmental Justice in Minority Populations and 
Low-Income Populations (Feb. 11, 1994). That E.O. was rescinded by E. 
O. 14173, Ending Illegal Discrimination and Restoring Merit-Based 
Opportunity (Jan. 21, 2025). Therefore, it is appropriate to remove the 
associated provision in Section 46.215.

[[Page 29502]]

    In addition, all references to E.O.s in the DOI list of 
extraordinary circumstances are removed. These E.O.s could change over 
time or could unduly limit the review of the resources listed, not 
allowing for more relevant information to be considered in the 
extraordinary circumstances review for a proposed action.
3. Applicant- and Contractor-Prepared Environmental Documents
    Finally, DOI is retaining and revising Section 46.105 and adding 
Section 46.107, which set standards and procedures that apply when DOI 
bureaus hire contractors to prepare environmental assessments, 
environmental impact statements, or other environmental information; or 
rely on applicants to prepare environmental information, including 
environmental assessments or environmental impact statements. The FRA 
provides that agencies may develop procedures to allow for the 
preparation of environmental assessments and environmental impact 
statements by applicants for Federal approvals. DOI already has a 
regulation allowing for bureaus to rely on applicant-prepared 
environmental assessments. The revisions made by this rule would extend 
that allowance to applicant-prepared environmental impact statements 
while also adding standards and procedures to ensure that the process 
for using applicant-prepared environmental assessments and 
environmental impact statements is both efficient and legally 
defensible. For similar reasons, additional standards and procedures 
have been added to the regulation governing bureau use of environmental 
information or documents prepared by contractors engaged directly by 
the bureaus.

III. Basis for Issuing an Interim Final Rule

A. Notice-and-Comment Rulemaking Is Not Required

    DOI is repealing its prior regulations that establish procedures 
and practices for implementing NEPA, a ``purely procedural statute'' 
which ``simply prescribes the necessary process' for an agency's 
environmental review of a project''--a review that is, even in its most 
rigorous form, ``only one input into an agency's decision and does not 
itself require any particular substantive outcome.'' Seven County, 145 
S. Ct. at 1507, 1511 (internal quotation omitted). ``NEPA imposes no 
substantive constraints on the agency's ultimate decision to build, 
fund, or approve a proposed project,'' and ``is relevant only to the 
question of whether an agency's final decision''--i.e., that decision 
to authorize, fund, or otherwise carry out a particular proposed 
project or activity--``was reasonably explained.'' Id. at 1511. As 
such, notice and comment procedures are not required because this 
revision falls within the APA exception for ``rules of agency 
organization, procedure, or practice.'' 5 U.S.C. 553(b)(A). DOI's 
existing NEPA regulations do not dictate what actions to take or 
policies to adopt. Rather, they prescribe how bureaus should conduct 
their NEPA reviews: detailing the application of NEPA, timing of 
environmental impact statements, and specifying other procedural 
requirements.\9\ These are procedural provisions, not substantive 
environmental ones, and they apply exclusively to internal DOI 
processes. And because procedural rules do not require notice and 
comment, absent a specific provision of law requiring such procedures, 
they do not require notice and comment to be rescinded. See 5 U.S.C. 
553(b)(A). Indeed, DOI recognized as much even when initially 
promulgating them: DOI was explicit that the department was codifying 
its procedures because it ``believes that codifying the procedures in 
regulations that are consistent with NEPA and the CEQ regulations will 
provide greater visibility to that which was previously contained in 
the DM and enhance cooperative conservation by highlighting 
opportunities for public engagement and input in the NEPA process.'' 73 
FR 61292.
---------------------------------------------------------------------------

    \9\ See 43 CFR part 46.
---------------------------------------------------------------------------

    Just so, DOI's new procedures will also be purely procedural and 
guide internal agency compliance with NEPA. Indeed, it is hard to see 
how they could be otherwise, since the Supreme Court has recently 
repeatedly emphasized that ``NEPA is a purely procedural statute.'' 
Seven County, 145 S. Ct. at 1507; see id. at 1510 (``NEPA is purely 
procedural. . . . NEPA `does not mandate particular results, but simply 
prescribes the necessary process' for an agency's environmental review 
of a project.''); id. at 1511 (NEPA is a purely procedural statute''); 
id. at 1513 (NEPA is properly understood as ``a modest procedural 
requirement''); id. at 1514 (``NEPA's status as a purely procedural 
statute''); see also id. at 1507 (``Simply stated, NEPA is a procedural 
cross-check, not a substantive roadblock.''). Procedures for 
implementing a purely procedural statute must be, by their nature, 
procedural rules. Surely, they cannot be legislative rules; as such, 
they do not need to be promulgated via notice-and-comment rulemaking. 
See 5 U.S.C. 553(b)(A). And even if that were not universally true, the 
new rules adopted in this notice are purely procedural.
    Moreover, even if (and to the extent that) DOI's regulations were 
not procedural rules, they may be characterized as interpretative rules 
or general statements of policy under 5 U.S.C. 553(b)(A). An 
interpretative rule provides an interpretation of a statute, rather 
than making discretionary policy choices that establish enforceable 
rights or obligations for regulated parties under delegated 
congressional authority. The definitions sections of both the old and 
new procedures, for instance, may be classified as such. General 
statements of policy provide notice of an agency's intentions as to how 
it will enforce statutory requirements, again without creating 
enforceable rights or obligations for regulated parties under delegated 
congressional authority. The prefatory sections of both the old and new 
procedures, for instance, may be classified as general statements of 
policy. Both of these types of agency action are expressly exempted 
from notice and comment by statute. 5 U.S.C. 553(b)(A), and so do not 
require notice and comment for their removal.
    Accordingly, although DOI is voluntarily providing notice and an 
opportunity to comment on this interim final rule, the agency has 
determined that notice-and-comment procedures are not required. The 
fact that DOI previously undertook notice-and-comment rulemaking in 
promulgating these regulations is immaterial: As the Supreme Court has 
held, where notice-and-comment procedures are not required, prior use 
of them in promulgating a rule does not bind the agency to use such 
procedures in repealing it. Perez v. Mortg. Bankers Ass'n, 575 U.S. 92, 
101 (2015).

B. DOI Has Good Cause for Proceeding With an Interim Final Rule.

    Moreover, DOI also finds that, to the extent that prior notice and 
solicitation of public comment would otherwise be required or this 
action could not immediately take effect, the need to expeditiously 
replace its existing regulations satisfies the ``good cause'' 
exceptions in 5 U.S.C. 553(b)(B) and (d). The APA authorizes agencies 
to issue regulations without notice and public comment when an agency 
finds, for good cause, that notice and comment is ``impracticable, 
unnecessary, or contrary to the public interest,'' 5 U.S.C. 553(b)(B), 
and to make the rule effective immediately for good cause. 5 U.S.C. 
553(d)(3). As discussed in Sections I &

[[Page 29503]]

II, above, DOI's prior rules were promulgated as a ``supplement . . . 
to be used in conjunction with,'' 43 CFR 46.20, CEQ's NEPA regulations. 
Following the rescission of CEQ's regulations, DOI's current rules are 
left hanging in air, supplementing a NEPA regime that no longer exists. 
DOI, thus far and as a temporary, emergency measure, has been 
continuing to operate under its prior procedures as if the CEQ NEPA 
regime still existed. This is not, however, tenable. As soon as updated 
non-regulatory procedures were available--which they are now--Interior 
must immediately rescind its duplicative or inconsistent regulations 
that compose this makeshift regime.
    For the same reasons stated in the present section, above, DOI 
finds that ``good cause'' exists under 5 U.S.C.Sec.  553(d)(3) to forgo 
the 30-day delay of the effective date that would otherwise be required 
to rescind regulations in their entirety. This interim final rule and 
the new procedural document that accompanies it will accordingly be 
effective immediately.

C. DOI Solicits Comment

    As explained above, comment is not required because DOI's NEPA 
procedures were and are procedural and because, even if comment were 
otherwise required under the APA, good cause exists to forgo it. 
Nevertheless, DOI has elected voluntarily to solicit comment. DOI is 
soliciting comment on this interim final rule and its new procedures, 
which are available for review at <a href="http://www.regulations.gov">www.regulations.gov</a>, docket number 
2025-0004. DOI may make further revisions to its NEPA implementing 
procedures, if DOI's review of any comments submitted suggests that 
further revisions are warranted. Commenters have 30 days from the date 
of publication of this interim final rule to submit comments.

IV. Regulatory Analyses and Notices

A. E.O. 12866, Regulatory Planning and Review, and E.O. 13563, 
Improving Regulation and Regulatory Review

    E.O. 12866 provides that OIRA will review all significant rules. 
E.O. 13563 reaffirms the principles of E.O. 12866, calling for 
improvements in the Federal Government's regulatory system to promote 
predictability, reduce uncertainty, and use the best, most innovative, 
and least burdensome tools for achieving regulatory objectives. OMB 
determined that this interim final rule is a significant regulatory 
action under E.O. 12866, as supplemented by E.O. 13563, and has 
reviewed.

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act, as amended, (RFA), 5 U.S.C. 601 et 
seq., and E.O. 13272 generally require agencies to assess the impacts 
of final rules on small entities by preparing a regulatory flexibility 
analysis. Under the RFA, small entities include small businesses, small 
organizations, and small governmental jurisdictions. The RFA applies 
only to rules for which an agency is required to first publish a 
proposed rule. See 5 U.S.C. 603(a) and 604(a). As the Department is not 
required to publish a notice of proposed rulemaking for this interim 
final rule, the RFA does not apply.
    Even if the RFA applies, this rule does not directly regulate small 
entities. Rather, the rule applies to Federal agencies and sets forth 
the process for their compliance with NEPA. Accordingly, DOI hereby 
certifies that this interim final rule will not have a significant 
economic impact on a substantial number of small entities.

C. Environmental Analysis

    DOI has determined that the rule will not have a significant effect 
on the environment because it will not authorize any specific agency 
activity or commit resources to a project that may affect the 
environment. Therefore, DOI does not intend to conduct a NEPA analysis 
of this interim final rule. In addition, DOI has determined that its 
categorical exclusion (CE) at 43 CFR 46.210(i) covers this rulemaking. 
The CE covers 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.'' 
Further, the proposed rule does not implicate any of the extraordinary 
circumstances listed in 43 CFR 46.215.

D. Executive Order 13132, Federalism

    E.O. 13132 requires agencies to develop an accountable process to 
ensure meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications. 
Policies that have federalism implications include regulations that 
have substantial direct effects on the States, on the relationship 
between the national government and the States, or on the distribution 
of power and responsibilities among the various levels of government. 
This interim final rule does not have federalism implications because 
it applies to Federal agencies, not States.

E. Executive Order 13175, Consultation and Coordination With Indian 
Tribal Governments

    E.O. 13175 requires agencies to have a process to ensure meaningful 
and timely input by Tribal officials in the development of policies 
that have Tribal implications. Such policies include regulations that 
have substantial direct effects on one or more Indian Tribes, on the 
relationship between the Federal Government and Indian Tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian Tribes. This interim final rule is not a 
regulatory policy that has Tribal implications because it does not 
impose substantial direct compliance costs on Tribal governments 
(section 5(b)) and does not preempt Tribal law (section 5(c)).

F. Executive Order 13211, Regulations That Significantly Affect Energy 
Supply, Distribution, or Use

    Agencies must prepare a Statement of Energy Effects for significant 
energy actions under E.O. 13211. This interim final rule is not a 
``significant energy action'' because it is not likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy.

G. Executive Order 12988, Civil Justice Reform

    Under section 3(a) of E.O. 12988, agencies must review their 
regulations to eliminate drafting errors and ambiguities, draft them to 
minimize litigation, and provide a clear legal standard for affected 
conduct. Section 3(b) provides a list of specific issues for review to 
ensure compliance with section 3(a). DOI has conducted this review and 
determined that this interim final rule complies with the requirements 
of E.O. 12988.

H. Unfunded Mandates Assessment

    Section 201 of the Unfunded Mandates Reform Act of 1995 (2 U.S.C. 
1531) requires Federal agencies to assess the effects of their 
regulatory actions on State, Tribal, and local governments and the 
private sector to the extent that such regulations incorporate 
requirements specifically set forth in law. Before promulgating a rule 
that may result in the expenditure by a State, Tribal, or local 
government, in the aggregate, or by the private sector of $100 million, 
adjusted annually for inflation, in any one year, an agency must 
prepare a written statement that assesses the effects on State, Tribal, 
and local governments and the private sector. 2

[[Page 29504]]

U.S.C. 1532. This interim final rule applies to Federal agencies and 
would not result in expenditures of $100 million or more by State, 
Tribal, and local governments, in the aggregate, or the private sector 
in any one year. This action also does not impose any enforceable duty, 
contain any unfunded mandate, or otherwise have any effect on small 
governments.

I. Paperwork Reduction Act

    This interim final rule does not impose any new information 
collection burden that would require additional review or approval by 
OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.

Subpart A--[Reserved]

Subpart B--Protection and Enhancement of Environmental Quality


Sec.  46.105  Using a bureau-directed contractor to prepare 
environmental documents.

    (a) A Responsible Official may use a bureau-directed contractor to 
prepare any environmental document.
    (b) If a Responsible Official uses a bureau-directed contractor, 
the Responsible Official remains responsible for:
    (1) Preparation and adequacy of the environmental documents; and
    (2) Independent evaluation of the environmental documents after 
their completion. The Responsible Official must briefly document the 
bureau's evaluation of the environmental document and ensure that it 
meets the standards under NEPA, this Part, and any Departmental or 
bureau-specific procedures or guidance.
    (c) The Responsible Official shall require any bureau-directed 
contractor preparing an environmental document to submit a professional 
integrity statement certifying that the environmental document is 
prepared with professional and scientific integrity, using reliable 
data and resources, and meets bureau needs for decision-making. In 
addition, the Responsible Official shall require any bureau-directed 
contractor preparing an environmental document to submit a disclosure 
statement specifying that the contractor has no financial or other 
interest in the outcome of the action.


Sec.  46.107  Procedures for applicant-prepared environmental impact 
statements and environmental assessments.

    In accordance with NEPA section 107(f), 42 U.S.C. 4336a(f), the 
following procedures are established for bureaus to allow applicants, 
or contractors directed by applicants, to prepare environmental impact 
statements and environmental assessments under bureau supervision when 
the bureau is the Federal lead agency.
    (a) A Responsible Official has discretion to allow an applicant or 
applicant-directed contractor to prepare an environmental impact 
statement or an environmental assessment (including analysis supporting 
these documents). A bureau may request more information, revise 
analysis methodologies, or choose not to use an environmental impact 
statement or an environmental assessment prepared by an applicant or 
its contractor at any time.
    (b) Applicants or applicant-directed contractors may not prepare 
decision documents, including records of decision.
    (c) The Responsible Official remains responsible for the accuracy, 
scope, and content of the environmental impact statement or 
environmental assessment and must independently evaluate and approve 
each such analysis before the bureau may use it. To maintain the 
scientific quality and integrity of the impact assessment, if in-house 
expertise is not available for the technical evaluations, another 
bureau or cooperating agency may be used, as needed, to verify the 
analyses if potential significance of an effect or issue is not clear.
    (d) Prior to a Responsible Official initiating the preparation of 
an environmental impact statement or an environmental assessment 
proposed to be prepared by an applicant or an applicant-directed 
contractor, the bureau must engage with the applicant and provide 
written documentation outlining the bureau's expectations regarding 
roles, responsibilities, the project schedule, coordination, 
deliverables (including draft and final documents), and supervision. 
Such engagement must occur within 30 days of the date initiating the 
preparation of an environmental impact statement or an environmental 
assessment.
    (e) If a Responsible Official uses information from an applicant or 
applicant-directed contractor to prepare an environmental impact 
statement or environmental assessment, the bureau must independently 
evaluate and provide written concurrence to the applicant or applicant-
directed contractor documenting that the information submitted meets 
the standards under NEPA, this Part, and any Departmental or bureau-
specific NEPA procedures or guidance. If a Responsible Official uses 
any of the following information prepared by an applicant or applicant-
directed contractor in initiating a review, such information must be 
submitted in writing to the Responsible Official for independent 
evaluation prior to initiating the NEPA process:
    (1) The purpose and need for the proposed action;
    (2) The proposed action and reasonable alternatives to the proposed 
action;
    (3) A community and stakeholder engagement plan;
    (4) Anticipated permits and authorizations required for the 
proposed action;
    (5) Anticipated cooperating agencies;
    (6) The process for consultations with relevant Federal agencies 
and State, Tribal, and local governments to ensure compliance with 
environmental laws and regulations.
    (7) Anticipated issues and resources to be analyzed in the 
environmental impact statement or environmental assessment, and summary 
of analysis methodology, as applicable; and
    (8) Schedule.
    (f) If a Responsible Official uses an environmental impact 
statement or environmental assessment prepared by

[[Page 29505]]

an applicant or applicant-directed contractor, the Responsible Official 
must independently evaluate and verify that the environmental analysis, 
including the methodologies used by the applicant or applicant-directed 
contractor, meets bureau standards and complies with NEPA, this Part, 
and any applicable Departmental or bureau-specific NEPA procedures or 
guidance. The applicant or applicant-directed contractor must provide 
the bureau with all relevant supporting information, including all 
studies, surveys, and technical reports pertaining to the environment 
prepared by the applicant or applicant-directed contractor for the 
proposed action. The applicant or applicant-directed contractor must 
certify that the materials provided to the bureau are complete for the 
bureau's independent review and inclusion in its decision file. The 
Responsible Official shall document the bureau's review and 
determination in any bureau-approved environmental impact statement or 
environmental assessment. The bureau is responsible for publishing all 
environmental impact statements and environmental assessments and, if 
an action is administratively or judicially challenged, for using the 
materials in its decision file to prepare an administrative record.
    (g) The Responsible Official shall require any applicant or 
applicant-directed contractor preparing an environmental impact 
statement or environmental assessment to submit a professional 
integrity statement certifying that the environmental analysis is 
prepared with professional and scientific integrity, using reliable 
data and resources, and meets any relevant Federal information quality 
standards and bureau needs for decision-making. In addition, the 
Responsible Official shall require any applicant or applicant-directed 
contractor preparing an environmental impact statement or an 
environmental assessment to submit a disclosure statement specifying 
any financial or other interest the entity has in the outcome of the 
action.
    Bureaus must publish or otherwise provide bureau-specific policy 
information to assist applicants preparing environmental impact 
statements or environmental assessments. Bureaus may provide additional 
guidance to Responsible Officials describing how to document the 
independent evaluation of environmental impact statements and 
environmental assessments to ensure that they meet the standards under 
NEPA and these implementing procedures.


Sec.  46.150  Emergency responses.

    This section applies only if the Responsible Official determines 
that an emergency exists that makes it necessary to take urgently 
needed actions before preparing an environmental document or 
documenting its use of a categorical exclusion in accordance with the 
provisions in this chapter.
    (a) The Responsible Official may take those actions necessary to 
control the immediate impacts of the emergency that are urgently needed 
to mitigate harm to life, property, or important natural, cultural, or 
historic resources. When taking such actions, the Responsible Official 
shall consider the probable environmental consequences of these actions 
and mitigate reasonably foreseeable adverse environmental impacts to 
the extent practicable.
    (b) The Responsible Official shall document in writing the 
determination that an emergency exists and describe the responsive 
actions taken at the time the emergency exists. The form of that 
documentation is within the discretion of the Responsible Official.
    (c) If the Responsible Official determines that the nature and 
scope of proposed actions that must be taken beyond actions noted in 
paragraph (a) of this section but in response and relation to such 
emergency action preclude preparation of an environmental document, the 
Responsible Official must consult with the Office of Environmental 
Policy and Compliance about alternative arrangements for NEPA 
compliance for such additional responsive actions. The Assistant 
Secretary, Policy Management and Budget may authorize the use of 
alternative arrangements. Reliance on any such alternative arrangements 
shall apply only to the proposed actions necessary to control the 
immediate actions in response and related to the emergency beyond those 
noted in paragraph (a) of this section and must be documented. 
Consultation with the Office of Environmental Policy and Compliance and 
with the Assistant Secretary, Policy Management and Budget must be 
coordinated through the appropriate bureau headquarters.
    (d) For actions meeting the criteria noted in paragraph (c) of this 
section that the Responsible Official reasonably foresees would be 
likely to result in significant effects, the Assistant Secretary, 
Policy Management and Budget or their designee must consult with the 
Council on Environmental Quality prior to authorizing the use of 
alternative arrangements for compliance with NEPA section 102(2)(C), 42 
U.S.C. 4332(2)(C).
    (e) Other proposed actions remain subject to compliance with NEPA 
and the remaining sections of this Part.

Subpart C--Initiating the NEPA Process


Sec.  46.205  Actions categorically excluded from further NEPA review.

    Categorical Exclusion means a category of actions that a bureau has 
determined normally do not significantly affect the quality of the 
human environment.
    (a) Except as provided in paragraph (c) of this section, if an 
action is covered by a Departmental categorical exclusion, the bureau 
is not required to prepare an environmental assessment or an 
environmental impact statement. If a proposed action does not meet the 
criteria for any of the listed Departmental categorical exclusions or 
any of the individual bureau categorical exclusions, then the proposed 
action must be analyzed in an environmental assessment or environmental 
impact statement.
    (b) The actions listed in Sec.  46.210 are categorically excluded, 
Department-wide, from preparation of environmental assessments or 
environmental impact statements.
    (c) DOI has provided for extraordinary circumstances in which a 
normally excluded action may have a significant environmental effect 
and require additional analysis. Section 46.215 lists the extraordinary 
circumstances under which actions otherwise covered by a categorical 
exclusion require analyses under NEPA.
    (1) Any action that is normally categorically excluded must be 
evaluated to determine whether it meets any of the extraordinary 
circumstances in Sec.  46.215; if it does, further analysis and 
environmental documents must be prepared for the action.
    (2) Bureaus must work within existing administrative frameworks, 
including any existing programmatic agreements, when deciding how to 
apply any of the Sec.  46.215 extraordinary circumstances.
    (d) Congress may establish categorical exclusions by legislation, 
in which case the terms of the legislation determine how to apply those 
categorical exclusions.
    (e) A Responsible Official may rely on another agency's 
determination that a categorical exclusion applies to a particular 
proposed action if the action covered by that determination and the 
bureau proposed action are substantially the same. The Responsible 
Official need not conduct extraordinary circumstances review according 
to the protocol set forth at Sec.  46.215 but must

[[Page 29506]]

document any reliance on another agency's categorical exclusion 
determination. When more than one agency is reviewing a proposed 
action, a bureau may also reach and document a joint determination with 
another agency that a categorical exclusion applies to the action.
    (f) Applying multiple categorical exclusions. Bureaus may apply 
multiple categorical exclusions in combination to cover a single 
proposed action. In some circumstances, the combination of categorical 
exclusions can cover all elements of a proposed action and support the 
bureau's determination that the effects of the proposed action, with 
all its elements, are not reasonably foreseeably to be significant. 
When a bureau completes its review of a proposed action in reliance on 
multiple categorical exclusions, the bureau must concisely document 
this reliance, including review for the presence of extraordinary 
circumstances that, if present, would preclude application of the 
categorical exclusions to the proposed action.
    (g) Each bureau may rely on any categorical exclusion 
administratively established or adopted, under NEPA section 109, 42 
U.S.C. 4336c, by the Department or any bureau within the Department.
    (h) To establish or revise a categorical exclusion, the Department 
will determine that the action is of a type that normally does not 
significantly affect the quality of the human environment. In making 
this determination and identifying and describing such a category, the 
Department will:
    (1) Develop a written record containing information to substantiate 
its determination;
    (2) Consult with the Council on Environmental Quality on its 
proposed categorical exclusion, including the written record, for a 
period not to exceed 30 days prior to providing public notice as 
described in subparagraph (3); and
    (3) Provide public notice in the Federal Register of establishment 
of the categorical exclusion and the location of availability of the 
written record.
    (i) Removal of categorical exclusions. To remove a categorical 
exclusion from its NEPA procedures, the Department will follow steps 
similar to those by which it establishes or revises a categorical 
exclusion.
    (j) Neither the establishment nor the modification or removal of a 
categorical exclusion from bureau NEPA procedures is subject to NEPA 
review.


Sec.  46.210  Listing of Departmental categorical exclusions.

    The following actions are categorically excluded under Sec.  
46.205(b), unless any of the extraordinary circumstances in Sec.  
46.215 apply and reliance on any of them to support approval of a 
proposed action need not be documented:
    (a) Personnel actions and investigations and personnel services 
contracts.
    (b) Internal organizational changes and facility and bureau 
reductions and closings.
    (c) Routine financial transactions including such things as 
salaries and expenses, procurement contracts (e.g., in accordance with 
applicable procedures and Executive Orders for sustainable or green
