National Environmental Policy Act Implementing Regulations

AGENCY: Office of the Secretary, Interior.

ACTION: Final rule.

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

SUMMARY: The Department of the Interior (Department or DOI) is adopting 
the interim final rule (IFR) published on July 3, 2025, with minor 
changes, as final. In the IFR, DOI provided a 30-day comment period for 
the public to review and make comments. This final rule addresses 
public comments and adopts as final the IFR, with certain substantive 
changes as explained herein. The IFR partially rescinded DOI's 
regulations implementing the National Environmental Policy Act (NEPA) 
and made necessary targeted updates to those provisions that were not 
repealed. DOI will henceforth maintain the majority of its NEPA 
procedures--which apply only to DOI's internal processes--in a 
Departmental Handbook separate from the Code of Federal Regulations 
(CFR).

DATES: This final rule is effective February 24, 2026.

FOR FURTHER INFORMATION CONTACT: Stephen G. Tryon, Director, Office of 
Environmental Policy and Compliance, 202-208-4221,

SUPPLEMENTARY INFORMATION:

I. Background

    DOI is issuing this final rule to adopt as final, subject to the 
revisions made by this final rule, the IFR promulgated on July 3, 2025. 
The IFR partially rescinded and made other needed, targeted updates to 
DOI's regulations, codified at 43 CFR part 46, implementing the 
National Environmental Policy Act of 1969, 42 U.S.C. 4321 et seq., as 
amended (NEPA). DOI's prior NEPA implementing regulations were 
promulgated in 2008 ``as a ``supplement[ ] . . . to be used in 
conjunction with'' the Council on Environmental Quality (CEQ)'s NEPA 
regulations. 43 CFR 46.20 (2008). 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) (2008). 
However, CEQ has now repealed its residual regulations, effective as of 
April 11, 2025. See Removal of National Environmental Policy Act 
Implementing Regulations, 90 FR 10,610 (February 25, 2025); Final Rule 
Removal of National Environmental Policy Act Implementing Regulations, 
91 FR 618 (January 8, 2026).
    Since DOI's regulations were originally designed to supplement 
CEQ's NEPA regulations, DOI awaited CEQ action before revising its own 
regulations. See 40 CFR 1507.3(b) (2024); see also 86 FR 34,154 (June 
29, 2021). Now that the removal of CEQ's regulations has been finalized 
through a final rule issued on January 8, 2026, DOI is issuing a final 
rule concurrently with its updated Department of the Interior Handbook: 
National Environmental Policy Act Implementing Procedures.
    DOI's foundation for the updates to its NEPA procedures is NEPA 
itself. Now that CEQ has rescinded its NEPA implementing regulations, 
see 91 FR 618 (Jan. 8, 2026) (final rule finalizing removal of CEQ's 
NEPA implementing regulations), DOI is issuing this final rule and NEPA 
Handbook in compliance with NEPA 102(2)(B), 42 U.S.C. 4332(2)(B), which 
directs all agencies of the federal government to identify and develop 
methods and procedures, in consultation with CEQ, to conduct the 
environmental analysis that NEPA requires.
    DOI, in its IFR, rescinded portions of its NEPA implementing 
regulations at 43 CFR part 46, while retaining and making targeted 
updates to certain provisions. Specifically, DOI retained and made 
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).
    In response to public comment on the IFR, DOI adds in this final 
rule a section on the designation of lead agencies and a section on the 
selection of cooperating agencies to codify the procedures by which 
Federal agencies and State, local, and Tribal agencies with special 
expertise continue to be involved in development of agency NEPA reviews 
(43 CFR 46.220 and 46.225, respectively). All other provisions were 
removed from 43 CFR part 46, consistent with DOI's IFR. Other than 
these few provisions, DOI's procedures are contained in the Department 
of the Interior Handbook: National Environmental Policy Act 
Implementing Procedures (referred to as DOI NEPA Handbook hereinafter), 
which is available in the DOI Electronic Library of the Interior 
Policies at https://www.doi.gov/document-library (but which will not be 
codified in the CFR). A section-by-section analysis is provided below 
highlighting where in the DOI NEPA Handbook concepts originally 
addressed in 43 CFR part 46 now appear.

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, 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 Infrastructure Coalition v. Eagle County, Colorado, 605 
U.S. 168, 173 (2025). 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

[[Page 8739]]

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 Infrastructure Coalition, 605 U.S. at 173; see also 
Department of Transportation v. Public Citizen, 541 U.S. 752, 756-57 
(2004). Rather, NEPA requires Federal agencies to consider the 
environmental effects of proposed actions as part of agencies' 
decision-making processes. As amended by the Fiscal Responsibility Act 
of 2023 (FRA), Public Law 118-5 (June 3, 2023), 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. 4336b, and adopt and use another agency's categorical 
exclusions. 42 U.S.C. 4336c.
    Finally, NEPA requires that ``copies of such [environmental impact 
statement] and the comments and views of the appropriate Federal, 
State, and local agencies, which are authorized to develop and enforce 
environmental standards, shall be made available to the President, the 
Council on Environmental Quality and to the public as provided by 
section 552 of title 5, United States Code, and shall accompany the 
proposal through the existing agency review processes.'' 42 U.S.C. 
4332. That is, NEPA provides that the extent to which a statement is 
made available to the public is governed by the requirements and 
standards of the Federal Freedom of Information Act (FOIA).

B. NEPA Regulations

1. Council on Environmental Quality (CEQ) NEPA Regulations
    On January 20, 2025, President Trump issued E.O. 14154, Unleashing 
American Energy. 90 FR 8,353 (Jan. 29, 2025). The E.O. revoked E.O. 
11991, Relating to protection and enhancement of environmental quality, 
42 FR 26,967 (May 25, 1977), which directed CEQ to issue regulations 
implementing NEPA and required Federal agencies to comply with those 
regulations. E.O. 14154 at sec. 5. 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. Id. at sec 5(a). The guidance 
and any resulting agency implementing regulations must ``expedite 
permitting approvals and meet deadlines established in the [FRA].'' Id. 
at sec 5(c). CEQ issued an IFR rescinding CEQ's NEPA implementing 
regulations (including as they relate to agency NEPA procedures) on 
February 25, 2025, effective April 11, 2025, 90 FR 10,610, which CEQ 
adopted as final on January 8, 2026, 91 FR 618. E.O. 14154 also 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 Departmental Manual chapters containing NEPA procedures through a 
notice-and-comment process required by CEQ NEPA regulations at the time 
that involved publication of proposed and final revisions in the 
Federal Register (FR), see 40 CFR 1507.3(a) (1978) (rescinded), 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, pursuant to direction in CEQ NEPA 
regulations that ``[t]hey shall confine themselves to implementing 
procedures'' and through a notice-and-comment process. 40 CFR 1507.3(a) 
(2005). DOI explained in the IFR its reasons for transitioning away 
from regulations and toward internal procedures, namely to allow DOI 
and its bureaus to implement changes in policy more quickly than would 
be possible while retaining the NEPA implementing regulations. DOI is 
affirming that approach and finalizing its internal procedures in 
parallel with issuing this final rule.
    DOI's new NEPA implementing procedures more closely align to the 
current iteration of the statute than its old procedures. The new 
procedures implement major structural features of the 2023 amendments, 
such as deadlines and page limits for environmental assessments and 
environmental impact statements, as directed at Section 107(g) of NEPA, 
and provide that DOI will complete preparation of these documents 
within the maximum timeline that Congress intends. They incorporate 
Congress's definition of ``major Federal action'' and the exclusions 
thereto, as codified at Section 111(10) of NEPA. They incorporate 
Congress's mandated procedure for determining the appropriate level of 
review under NEPA, as codified in Section 106 of NEPA. And they 
incorporate Congress's revision to the requirements for what an agency 
must address in its environmental impact statements, as codified at 
Section 102(2)(C) of NEPA, 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 
Section 107(c) of NEPA. These are all crucial features of Congress's 
policy design and its purpose in enacting the 2023 amendments that NEPA 
review be more efficient and certain.
    These procedures, therefore, attempt to align NEPA with its 
Congressionally mandated dimensions, Presidential directives, and 
Supreme Court precedent, making review faster, more flexible, and more 
efficient.
    No third parties have cognizable reliance interests in DOI's 
existing NEPA procedures. 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 long held, 
and just reaffirmed, NEPA ``is a purely procedural statute'' that 
``imposes no substantive environmental obligations or restrictions.'' 
Seven County Infrastructure Coalition, 605 U.S. at 173; Public Citizen, 
541 U.S. at 756; Vermont Yankee Nuclear Power Corp. v. NRDC, 435 U.S. 
519, 558 (1978). To the extent any asserted reliance interests are 
grounded in substantive environmental concerns, such interests are not 
entitled to any weight as to this rulemaking, given that DOI's 
procedures simply provide the process by which a bureau accounts for 
environmental considerations, rather than determining the substantive 
policy or decision on an individual application or project. See, e.g., 
Dep't of Homeland Sec. v. Regents of the Univ. of California, 591 U.S. 
1, 32 (2020).
    DOI provided an opportunity to comment on its IFR and considered 
comments in issuing its final rule and DOI NEPA Handbook. Comments were 
considered and addressed, which included revising DOI NEPA

[[Page 8740]]

procedures. A summary of comments and responses on the rulemaking are 
addressed in section III below.
    As explained in the IFR, 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 
difficulties associated with the NEPA process and NEPA litigation 
identified by the Supreme Court in Seven County Infrastructure 
Coalition. 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. After considering public 
comments, DOI has adopted the IFR in this final rule, subject to the 
revisions explained below.

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. See 42 U.S.C. 4332(2)(B). 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.

B. Retaining and Revising Certain Provisions

    The IFR removed most of the existing DOI NEPA regulations in favor 
of relying on Departmental guidance for the reasons discussed in the 
IFR and summarized above, but the rule retained and made targeted 
updates to its regulations that authorize four tools that DOI bureaus 
rely on, when appropriate, to expedite NEPA reviews and ensure that 
compliance with NEPA is achieved in an efficient manner. The final rule 
reaffirms this approach and reserves for Departmental guidance most of 
the substance of the provisions from the regulations previously in 
place.
1. Emergency Responses
    First, DOI retained 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'' or 
relying on alternative arrangements for NEPA compliance to take other 
actions beyond those immediately necessary to protect life, property, 
and resources in response to emergencies. The IFR made minor clarifying 
adjustments to the text that reflect DOI's experience implementing 
these provisions. The final rule revises 43 CFR 46.150 to clarify that 
NEPA's analysis and documentation requirements should not impede timely 
execution of actions needed to address imminent threats to life, 
property, or important natural, cultural, or historic resources. For 
such actions, the responsible official may take such actions without 
conducting a NEPA review. The responsible official is directed to take 
into account the probable environmental consequences of the action and 
consider taking steps to mitigate reasonably foreseeable adverse 
environmental effects to the extent practical and consistent with 
agency authority.
2. Categorical Exclusions
    DOI retained 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 lengthier environmental 
assessment or environmental impact statement process and can proceed 
using the shorter 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 IFR revised them to refine the description of, or, in some cases, 
remove certain extraordinary circumstances that, when present, would 
preclude reliance on a categorical exclusion. Section 46.205 of the 
IFR, meanwhile, included new paragraphs (e) through (j), which provide 
that DOI bureaus may rely on categorical exclusion determinations made 
by other agencies, may apply multiple categorical exclusions to a 
proposed action that is a composite of multiple smaller actions or 
action elements, and may rely on a categorical exclusion 
administratively established or adopted by another DOI bureau; 
establish procedures to govern the establishment, modification, or 
removal of categorical exclusions from NEPA procedures; and clarify 
that any such establishment, modification, or removal does not itself 
have any environmental effects for purposes of NEPA. (The IFR also 
eliminated certain categorical exclusions from Section 46.210 on the 
basis that they were not used across the Department; as noted below, 
the final rule restores those categorical exclusions to the regulation 
to ensure continuity in reference and citation.)
    In the final rule, DOI adds cross references to paragraphs (d) and 
(e) in paragraph (a) of Section 46.205 for additional clarity. Public 
comment on the IFR requested this clarification. In addition, DOI is 
revising paragraph (f) with non-substantive and clarifying editorial 
changes. Finally, DOI is removing errant paragraph topic headings in 
paragraph (f) and (i) for consistency with the rest of the section, 
which does not use this organizational format.
    In Section 46.210, the final rule reinstates paragraphs (k) and (l) 
which had been removed in the IFR, and which describe categorical 
exclusions for hazardous fuels reduction activities using prescribed 
fire and post-fire rehabilitation activities, respectively. Although 
they are not properly considered Department-wide categorical 
exclusions, bureaus have relied on this regulatory citation since the 
2008 DOI NEPA rule, and DOI reorganized the bureau-specific categorical 
exclusion list in the DOI NEPA Handbook to consolidate the list in a 
more user-friendly format to facilitate use. DOI also identifies 
limitations in this final rule on use of the hazardous fuels reduction 
activities categorical exclusion in paragraph (k), revising the 
regulatory text to add a limitation on its use in States under the 
jurisdiction of the Ninth Circuit Court of Appeals. In addition, DOI is 
revising the introductory paragraph in this section to provide that 
reliance on either of the two categorical exclusions described in 
paragraphs (k) and (l) requires documentation, consistent with the

[[Page 8741]]

2008 DOI NEPA regulation, and revising text to provide that reliance on 
any of the other categorical exclusions in paragraph (a) through (j) 
does not require documentation, again consistent with the 2008 DOI NEPA 
regulation. 43 CFR 46.20(c) (2008).
    In Section 46.215, which lists the ``extraordinary circumstances'' 
that, if present, preclude use of a categorical exclusion, the IFR 
removed legacy paragraphs (c), (i), and (j), and then renumbered the 
remaining paragraphs.
    Legacy paragraph (c) had provided 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) (2008). 
This provision caused confusion as it was frequently misunderstood to 
mean that any controversy surrounding the substance of the action--as 
opposed to controversy about the nature or magnitude of the 
environmental effects, which was the appropriate, limited focus of the 
provision--itself constitutes an extraordinary circumstance. In any 
event, the concept is sufficiently addressed in legacy paragraph (d) 
(which the IFR renumbered as paragraph (c)), which addresses proposed 
actions that have highly uncertain and potentially significant 
environmental effects or involve unique or unknown environmental risks. 
DOI makes no changes to this paragraph in the final rule.
    Legacy paragraph (i) had provided 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) (2008). 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 Official 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 or the analysis of what those effects 
are. DOI makes no changes to this paragraph in the final rule.
    Legacy paragraph (j) had been 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, 90 FR 8633 (Jan. 31, 2025). Therefore, it was 
appropriate to remove the associated provision in Section 46.215, and 
DOI makes no changes to this paragraph in the final rule.
    In addition, all references to E.O.s in the DOI list of 
extraordinary circumstances were 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. Further, the 
E.O.s in force when an agency proposes action are, if relevant, 
authoritative in their own right, regardless of whether they are set 
forth in these regulations.
3. Applicant- and Contractor-Prepared Environmental Documents
    In the IFR, DOI also retained Section 46.105, with some revisions, 
and added Section 46.107. These sections 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. Section 107(f) of NEPA, enacted through the FRA, 
requires agencies to develop procedures to allow for the preparation of 
environmental assessments and environmental impact statements by 
applicants for Federal approvals. DOI already had a regulation allowing 
for bureaus to rely on applicant-prepared environmental assessments. 
The revisions made by the IFR extended 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 were added to the regulation governing bureau 
use of environmental information or documents prepared by contractors 
engaged directly by the bureaus.
    The final rule affirms the IFR by retaining Section 46.105 with a 
minor revision that adds references to NEPA and a DOI Secretarial 
Order. In paragraph (c) of Section 46.107, DOI removes the last phrase 
``if potential significance of an effect or issue is not clear,'' which 
described when another agency may be used to verify analyses in an 
environmental assessment or environmental impact statement. DOI 
determined that this phrase was unnecessary and could be unduly 
limiting when in-house expertise is not available and DOI seeks to rely 
on another agency's expertise regarding the scientific quality and 
integrity of an impact assessment.
4. How To Designate Lead Agencies
    In the final rule, DOI reinstates Section 46.220, How to designate 
lead agencies, as modified from legacy paragraph 1.7(a) from the DOI 
NEPA Handbook, How to designate lead agencies, and makes formatting 
changes to align with the format for rules. In response to public 
comment and to keep the roles of those agencies in the NEPA process 
together in the DOI NEPA implementing procedures, DOI elects to re-
codify this section and the next section, 46.225, in the final rule.
5. How To Select Cooperating Agencies
    In the final rule, DOI reinstates Section 46.225, How to select 
cooperating agencies, as modified from legacy paragraph 1.7(b) from the 
DOI NEPA Handbook, How to select cooperating agencies. In doing so, DOI 
amends the term ``eligible governmental entity'' to ``agency'' to align 
with NEPA and CEQ guidance in memorandum, Implementation of the 
National Environmental Policy Act, Appendix 1--Agency NEPA Procedures 
Template, and makes editing and formatting changes to align with the 
format for rules. In addition, DOI corrected ``must'' to ``may'' in the 
provision regarding inviting cooperating agencies when preparing an 
environmental assessment, which corresponds to DOI's previous NEPA 
procedures and the text of NEPA. Finally, DOI added a clarifying phrase 
regarding documentation with cooperating agencies on their roles to 
explicitly note the potential limitations of laws on the 
confidentiality of pre-publication environmental documents. In response 
to numerous public comments requesting that DOI retain the procedures 
for including cooperating agencies in NEPA reviews in regulation, DOI 
elects to re-codify this section in the final rule to ensure that the 
agency's procedures effectively describe the process for selecting 
cooperating agencies and to promote maximum efficiency and cross-agency 
work in service of timely environmental reviews.

C. Establishing DOI's NEPA Handbook

    In this section, DOI provides a section-by-section summary of the 
provisions of DOI's NEPA Handbook. Though the Handbook is not part of 
the rulemaking, DOI is electing to provide this summary to assist the 
public in understanding the relationship between DOI's rulemaking and 
other updates to its NEPA procedures. In DOI's 2025 IFR, DOI explained 
that it was moving much of the material previously contained within its 
NEPA procedures in the CFR to a non-regulatory handbook. When 
publishing its IFR, DOI solicited comment on its revision of its NEPA 
procedures, including this step of transferring much of the procedures 
into the handbook. This section and the response to comments in section 
III below explain the contents of the handbook and respond to comments.
1. Section 0.1--Purpose and Policy
    Section 0.1 of the DOI NEPA Handbook describes the purpose of the 
document and makes clear that the Handbook, together with the handful 
of provisions retained in regulation, constitute DOI's NEPA procedures. 
This section was revised from the version of the Handbook released in 
July 2025 with the IFR to provide explicitly that ``environmental 
information'' relevant to a decision-maker may include ``economic 
information'' and clarify that the Handbook is meant only to guide 
bureaus in their efforts to comply with NEPA and not with other legal 
obligations that may apply to a proposed action.
2. Section 0.2--Applicability
    Section 0.2 of the DOI NEPA Handbook describes the extent of the 
applicability of the guidance document and provides that it applies to 
all DOI bureaus.
3. Section 1.1--Determining When NEPA Applies
    Section 1.1 of the DOI NEPA Handbook guides DOI bureaus on the 
standards for when the bureau must comply with NEPA, including what 
constitutes a ``major Federal action[ ]'' within the meaning of the 
statute. 42 U.S.C. 4332(C). Some commenters took exception to the 
statement in that discussion that ``[t]he terms `major' and `Federal 
action[ ]' each have independent force.'' DOI NEPA Handbook 
1.1(a)(6)(i). Each word of the statute should be given weight. In this 
instance, Congress has itself defined the phrase, excluding certain 
kinds of proposed actions from its ambit, and in so doing repeated its 
two component terms first introduced in 1969. This interpretation that 
each term has a distinct meaning is also consistent with the 
interpretation of the statutory language in the period soon after 
NEPA's enactment, before the first CEQ NEPA regulations.
    This section was revised from the version of the Handbook released 
in July 2025 with the IFR to remove references to an appendix listing 
examples of classes of actions that normally require an environmental 
assessment or environmental impact statement, which has been 
eliminated, and to clarify that the reason that the activities 
identified in Section 1.1(a)(6)(iii) do not usually require preparation 
of an environmental document is that they usually do not result in 
significant environmental effects and not necessarily that they are not 
``major Federal actions.''
4. Section 1.2--Determining the Appropriate Level of NEPA Review
    Section 1.2 of the DOI NEPA Handbook presents the standards for 
determining, once it is established that NEPA applies, whether the 
bureau may use a categorical exclusion, prepare an environmental 
assessment, or prepare an environmental impact statement. Bureaus will 
prepare an environmental impact statement if the bureau anticipates 
that ``the reasonably foreseeable effects of the proposed action or 
action alternatives would be significant.'' DOI NEPA Handbook 1.2(b).
    Some commenters took issue with the provision allowing that, ``[i]f 
the proposed action warrants the establishment of a new categorical 
exclusion, or the revision of an existing categorical exclusion, 
pursuant to section 1.4(b), the bureau will consider whether to so 
establish or revise, and then may apply the categorical exclusion to 
the proposed action,'' DOI NEPA Handbook 1.2(a)(3), and perceived it as 
a means of circumventing the usual process for establishing new or 
revising existing categorical exclusions.
    DOI has revised this particular provision from the version of the 
Handbook released in July 2025 to make explicit that any establishment 
or revision of a categorical exclusion will follow the standard 
procedures. It is wholly appropriate for DOI bureaus to consider 
establishing a new categorical exclusion when confronted with an action 
of a type it has found normally does not significantly affect the 
quality of the human environment but for which no categorical exclusion 
has already been established.
    Some commenters took issue with the criteria listed in this 
section, comparing those criteria to the treatment of ``significance'' 
under the 2024 CEQ regulations and objecting to the inclusion of 
``[e]conomic effects'' and ``[e]ffects on the quality of life of the 
American people'' among those criteria to the exclusion of others.
    The criteria identified in Section 1.2(b)(2) are necessarily 
defined at a high level of generality--e.g., ``short- and long-term 
effects,'' DOI NEPA Handbook 1.2(b)(2)(i), and the inclusion of 
references generally to economic and other quality of life impacts does 
not, as commenters suppose, prioritize those concepts above impacts to 
other environmental resources encompassed within but not explicitly 
listed among the broad criteria included in the Handbook. DOI has 
determined that this higher level of generality better reflects the 
broad understanding of ``significance'' under the statute than would an 
attempt to define the concept with more particularity, as CEQ did in 
2024 and as some commenters appear to prefer.
    Moreover, 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). Given the statutory language as it 
relates to fulfilling the social and economic requirements of present 
and future generations, and DOI's longstanding practice in integrating 
its consideration of social impacts into its environmental analysis 
under NEPA, DOI finds it appropriate to continue to consider social 
effects, including economic effects, when evaluating environmental 
effects under NEPA.
    This section was revised to make explicit that a bureau may, in 
determining whether an action will have significant effects, consider 
beneficial effects that directly offset adverse effects to a given 
resource value. DOI NEPA Handbook 1.2(b)(2).
5. Section 1.3--NEPA and Agency Decision-Making
    Section 1.3 of the DOI NEPA Handbook describes the relationship 
between the NEPA process and other DOI and bureau processes and 
decisions. It includes direction to integrate the NEPA process with 
other processes as soon as practicable and articulates the limitations 
on bureau decision-making while the NEPA

[[Page 8743]]

process is underway. DOI NEPA Handbook 1.3(a)-(b). This direction is 
consistent with long-standing CEQ and DOI NEPA guidance. See 40 CFR 
1500.4(k); 40 CFR 1502.25(a) (1978) (rescinded); 43 CFR 46.430 (2008) 
(rescinded in part). It identifies important (largely practical) 
considerations in cases where the bureau action will be in response to 
a third-party application and where it will be a bureau rulemaking. DOI 
NEPA Handbook 1.3.(c)-(d). DOI revised these paragraphs (c) and (d), 
relative to the version of the Handbook released in July 2025, to 
provide additional detail.
    Finally, section 1.3(e) provides standards for evaluating 
mitigation measures within the range of alternatives, with the 
important caveat that NEPA itself does not provide authority for a 
bureau to require or implement mitigation measures. DOI NEPA Handbook 
1.3(e). The provisions in the DOI NEPA Handbook are consistent with the 
long-standing provisions in both the original CEQ and DOI NEPA 
regulations, including the definition of ``mitigation.'' See 40 CFR 
1500.3 (describing the mandate of the regulations as ``applicable to . 
. . implementing the procedural provisions of NEPA'') (1978) 
(rescinded); 40 CFR 1502.14(f) (1978) (rescinded), 1508.20 (1978) 
(setting forth the types of ``mitigation''; rescinded); 43 CFR 46.130 
(2008) (rescinded in part). Some commenters suggested that DOI should 
provide more detail in its procedures as to how to consider mitigation 
in NEPA reviews, even as those comments acknowledged that the 
procedures do address the topic. This section articulates the 
proposition that ``NEPA requires bureaus to consider reasonable 
mitigation measures,'' and it and other provisions within the Handbook 
provide appropriate standards for Responsible Officials to fulfill that 
obligation. DOI acknowledges that CEQ took a more granular approach in 
its 2024 Rule, but DOI has determined that the higher level of 
generality expressed in the DOI NEPA Handbook will provide Responsible 
Officials with the flexibility and reasonable discretion needed to 
efficiently carry out their duties consistent with NEPA's requirements. 
DOI NEPA Handbook 1.3(e); see also DOI NEPA Handbook 1.6(a)(3), 
2.3(a)(6).
6. Section 1.4--Categorical Exclusions
    Section 1.4 of the DOI NEPA Handbook concerns categorical 
exclusions. Because the DOI NEPA procedures for categorical exclusions 
have been maintained as regulations, this section consists largely of 
cross-references to the appropriate regulatory section for the 
establishment, adoption, application, and documentation of categorical 
exclusions. See Section II.B.2, supra.
    This section was revised from the version of the Handbook released 
in July 2025 with the IFR to provide additional details for considering 
whether a categorical exclusion applies to a proposed action that has 
been modified.
7. Section 1.5--Environmental Assessments
    Section 1.5 of the DOI NEPA Handbook identifies and describes the 
considerations relevant to the preparation of an environmental 
assessment. It addresses both the character of environmental 
assessments as set forth in the statute, and is consistent with long-
standing provisions in both the original CEQ and DOI NEPA regulations 
(see 40 CFR 1508.9) (1978) (rescinded); 43 CFR 46.300, 310 (2008) 
(rescinded), including the elements they include and their appropriate 
scope, as well as more technical details, including page limits, 
timeframes for preparation, and certification. This section was revised 
from the version of the Handbook released in July 2025 with the IFR to 
add discussion of Section 112 of NEPA, enacted after the Handbook was 
first released, and to eliminate references to the appendix listing 
examples of classes of actions that normally require an environmental 
assessment (but not an environmental impact statement). DOI has 
determined that this appendix was not useful because the amendments to 
the statute and DOI's NEPA implementing procedures as adopted in the 
2025 IFR, this final rule, and elsewhere in its NEPA Handbook provide 
sufficient guidance as to when DOI is required to develop an 
environmental assessment, and it is not included in the revised version 
of the Handbook.
8. Section 1.6--Findings of No Significant Impact
    Section 1.6 of the DOI NEPA Handbook details the procedures that 
bureaus follow when making and documenting a finding of no significant 
impact. As noted above in the discussion of section 1.3(e), this 
section provides that a finding of no significant impact will 
``identify the mitigation measures that will be undertaken to avoid 
significant effects and the mechanisms to ensure their 
implementation.'' DOI NEPA Handbook 1.6(a)(3). No changes have been 
made to this section relative to the version released with the IFR in 
July 2025.
9. Section 1.7--Lead and Cooperating Agencies
    Section 1.7 of the DOI NEPA Handbook concerns identification of a 
lead agency in cases where more than one agency will participate in a 
NEPA process and procedures for engaging with the broader set of 
cooperating agencies. The substance that appeared in the July 2025 
version of the Handbook that accompanied the IFR has been moved to the 
regulations at 43 CFR 46.220 and 46.225; therefore, this section now 
consists primarily of cross-references to those provisions. See also 
Section II.B.4-5, supra.
10. Section 1.8--Notices of Intent and Scoping
    Section 1.8 of the DOI NEPA Handbook describes DOI's procedures for 
the scoping process that precedes development of an environmental 
document, including the process for issuing a notice of intent to 
prepare an environmental impact statement. Paragraph (b) of this 
section provides that when a bureau intends to prepare an environmental 
impact statement to evaluate a proposed action, the bureau must publish 
a notice of intent in the Federal Register. The notice of intent 
process includes an opportunity for public comment, as is required by 
statute. 42 U.S.C. 4336a(c). Paragraph (c) of this Handbook section 
includes examples of other steps bureaus might take as part of the 
scoping process. Paragraph (a) has been revised from what appeared in 
the July 2025 version of the Handbook for clarity.
11. Section 2.1--Preparation of Environmental Impact Statements
    Section 2.1 reiterates the standard for when an environmental 
impact statement is required, as well as the expectations and 
procedures for soliciting comments from Federal agencies; State, 
Tribal, and local governments and agencies; and the public. This 
section was revised from the version of the Handbook released in July 
2025 with the IFR to eliminate references to the appendix listing 
examples of actions that normally require an environmental impact 
statement. DOI has determined that this appendix was not useful, and it 
is not included in the revised version of the Handbook.
    Many comments addressed DOI's approach to public participation in 
the IFR and Handbook. Those comments are relevant to this section of 
the Handbook but generally address the question of public participation 
more broadly. For a

[[Page 8744]]

consolidated response to those comments, see Section III.E, infra.
12. Section 2.2--Purpose and Need
    Section 2.2 provides guidance on developing the statement of 
purpose and need that is included in all environmental impact 
statements, including the particular considerations that are present 
when a bureau's proposed action responds to an application from a third 
party. Some commenters took issue with the provision that, in such 
circumstances, ``the purpose and need for the proposed action will also 
be informed by the goals of the applicant,'' claiming that it would 
limit consideration of appropriate alternatives to the proposed action. 
DOI disagrees because while the provision requires Responsible 
Officials to consider the applicant's goals when reasonably defining 
the purpose and need for a proposed action, it does not require those 
officials to adopt the applicant's goals as the bureau's purpose and 
need or exclude from consideration otherwise reasonable alternatives to 
the proposed action. DOI also notes that DOI's 2008 NEPA regulations 
included the directive that when considering such applications, ``the 
bureau should consider the needs and goals of the parties involved in 
the application or permit as well as the public interest,'' see 43 CFR 
46.420(a)(2) (rescinded), and that this concept is merely carried into 
this section of the DOI NEPA Handbook. No changes have been made to 
this section relative to the version released with the IFR in July 
2025.
13. Section 2.3--Analysis Within the Environmental Impact Statement
    Section 2.3 outlines the content of an environmental impact 
statement, providing guidance on what should be included, which closely 
tracks the statutory requirements at 42 U.S.C. 4332(C); and provides 
guidance about how to determine the appropriate scope of the analysis, 
including by incorporating concepts and language from the Supreme 
Court's recent consideration of that issue in Seven County 
Infrastructure Coalition. Compare DOI NEPA Handbook 2.3(b)(3) (``To the 
extent it assists in reasoned decision-making, the bureau may, but is 
not required to by NEPA, analyze environmental effects from other 
projects separate in time, or separate in place, or that fall outside 
of the bureau's regulatory authority, or that would have to be 
initiated by a third party.''), with Seven County Infrastructure 
Coalition, 605 U.S. at 182 (``So long as the EIS addresses 
environmental effects from the project at issue, courts should defer to 
agencies' decisions about where to draw the line--including (i) how far 
to go in considering indirect environmental effects from the project at 
hand and (ii) whether to analyze environmental effects from other 
projects separate in time or place from the project at hand.'').
    Section 2.3(a)(3) directs bureaus to identify and evaluate the 
environmental effects of ``a reasonable range of alternatives to the 
proposed action.'' DOI NEPA Handbook 2.3(a)(3); see also 42 U.S.C. 
4332(C)(iii). Some commenters suggested that DOI should or must 
incorporate into its guidance additional direction concerning the 
development and selection of alternatives from CEQ's rescinded 
regulations. The guidance concerning the identification and 
consideration of alternatives in DOI's Handbook substantially aligns 
with the content of CEQ's now-rescinded regulations and CEQ guidance, 
including that bureaus must consider a reasonable range of 
alternatives, see 40 CFR 1502.14(a) (1978) (rescinded); see also Forty 
Most Asked Questions Concerning CEQ's National Environmental Policy Act 
Regulations, Question and Answer 1b (``When there are potentially a 
very large number of alternatives, only a reasonable number of 
examples, covering the full spectrum of alternatives, must be analyzed 
and compared in the EIS.''), 46 FR 18,026 (March 23, 1981).
    But, as noted above, DOI's Handbook is not simply a subsequent 
iteration of the policies previously contained in CEQ's now-rescinded 
regulations, or a direct successor to them, but rather draws upon and 
implements the requirements of NEPA itself. Based on its experience and 
judgment, DOI believes that the guidance it is providing in Section 
2.3(a)(3) better hews to the statutory language and better guides 
bureaus in developing alternatives to a given proposed action than 
would reconstituting the particular approach taken by the now-rescinded 
CEQ regulations. For example, one commenter noted while the version of 
the Handbook released in July 2025 expressly provides that 
environmental assessments do not need to include a ``no action 
alternative,'' the Handbook is not clear whether environmental impact 
statements must include a ``no action alternative.'' DOI agrees. The 
DOI Handbook, Appendix 1, has now been revised to encourage, but not 
require, DOI bureaus to include a ``no action alternative'' in both 
environmental assessments and environmental impact statements. While 
including a ``no action alternative'' is often useful to compare the 
effects of the proposed action to the future without the Federal 
action, it is not always necessary; no specific invocation of a ``no 
action alternative'' is necessary as the effects of the proposed action 
and any reasonable alternatives thereto would necessarily be described 
in terms of change to the prevailing circumstances or ``Affected 
Environment.''
    No other changes have been made to this section relative to the 
version released with the IFR in July 2025.
14. Section 2.4--Page Limits
    Section 2.4 provides that environmental impact statements must be 
no more than 150 pages or, where the proposed action is of 
extraordinary complexity, 300 pages, consistent with statutory limits 
enacted in the 2023 amendments to NEPA. See 42 U.S.C. 4336a(e). The 
section also provides that the Responsible Official will certify that 
the environmental impact statement appropriately prioritizes the most 
important considerations for the analysis in light of both the page 
limitation and the factors that the bureau must consider under NEPA. 
The section has been revised from the version of the Handbook released 
in July 2025 with the IFR to clarify that citations and appendices are 
not counted toward the page limit.
15. Section 2.5--Deadlines
    Section 2.5 provides guidance and direction on compliance with 
NEPA's deadlines for completing an environmental impact statement under 
both Section 107 and Section 112 of the statute. It also directs the 
Responsible Official to certify that the environmental impact statement 
has thoroughly considered the factors that the bureau must consider 
under NEPA while making a good-faith effort to fulfill NEPA's 
requirements within the statutory deadlines. This section was revised 
from the version of the Handbook released in July 2025 with the IFR to 
add discussion of Section 112 of NEPA, enacted after the Handbook was 
first released.
16. Section 2.6--Publication of the Environmental Impact Statement
    Section 2.6 directs bureaus to make environmental impact statements 
available to the public. No changes have been made to this section 
relative to the version released with the IFR in July 2025.

[[Page 8745]]

17. Section 3.1--Reliance on Existing Environmental Documents
    Section 3.1 provides guidance for bureaus when they seek to use a 
previously prepared environmental document to satisfy their NEPA 
compliance obligations with respect to a new proposed action. The 
section identifies the standards for making a Determination of NEPA 
Adequacy or similar finding, including by providing detail on what 
constitutes ``substantial similarity.'' Some commenters objected to the 
allowance that bureaus should provide for public comment when they plan 
to rely on a previously prepared environmental document only ``to the 
extent that solicitation of comment will assist the bureau in 
expeditiously adapting the relied-upon statement or assessment so that 
it is fit for the bureau's purposes.'' See DOI NEPA Handbook 3.1(b)(2). 
While those comments are specific to this section of the Handbook, they 
join many other comments addressed to DOI's approach to public 
participation in general. For a consolidated response to those 
comments, see Section III.E, infra.
    No changes, beyond one technical correction, have been made to this 
section relative to the version released with the IFR in July 2025.
18. Section 3.2--Programmatic Environmental Impact Statements or 
Environmental Assessments and Tiering
    Section 3.2 articulates guidance and details the procedures for 
preparing programmatic environmental assessments and environmental 
impact statements. The section tracks the statutory provisions for 
programmatic environmental documents at Section 108 to describe the 
circumstances under which a bureau may rely on a programmatic 
environmental document, without further NEPA review as well as when a 
bureau may, in the course of additional NEPA review, tier to an 
existing programmatic environmental assessment or environmental impact 
statement so as to truncate additional review. Finally, the section 
provides that a bureau may prepare an environmental assessment and 
reach a finding of no additional significant impacts when it tiers to a 
programmatic environmental impact statement that has already fully 
analyzed any significant effects the proposed action would have. This 
provision carries forward a clarification in tiering practice 
introduced in DOI's 2008 NEPA regulations. See 43 CFR 46.140 
(rescinded). No changes have been made to this section relative to the 
version released with the IFR in July 2025.
19. Section 3.3--Publishing Pre-Decisional Environmental Documents
    Section 3.3 provides allowance for a bureau to release drafts of 
environmental documents and other pre-decisional materials when doing 
so ``may assist in fulfilling its responsibilities under NEPA.'' No 
changes have been made to this section relative to the version released 
with the IFR in July 2025.
20. Section 3.4--Combining Documents
    Section 3.4 directs bureaus to combine environmental documents 
prepared to comply with NEPA with other bureau documents prepared in 
the course of making a decision to pursue the proposed action to the 
fullest extent practicable. This provision is designed to increase 
efficiency and decrease the extent of the materials to support agency 
decision-making. No changes have been made to this section relative to 
the version released with the IFR in July 2025.
21. Section 3.5--Incorporation by Reference
    Section 3.5 describes the allowance for bureaus to incorporate 
other materials by reference, to reduce the length of environmental 
documents. When incorporating by reference, bureaus must describe the 
content briefly and provide relevant citation to the material being 
incorporated. This is consistent with a provision in the 2008 DOI NEPA 
regulations. See 43 CFR 46.135 (rescinded). With respect to cost-
benefit analysis specifically, although NEPA itself does not require 
preparation of a cost-benefit analysis, these procedures direct bureaus 
to incorporate any cost-benefit analysis they do prepare by reference 
in the associated environmental document. This provision is consistent 
with long-standing guidance in the CEQ regulations. See 40 CFR 1502.23 
(1978) (rescinded). In DOI's judgment, retaining it is compatible with 
the statute, will enhance DOI's ability to comply with the statutory 
page limits and deadlines, and will otherwise further the policies of 
E.O. 14154. No changes, beyond one technical correction, have been made 
to this section relative to the version released with the IFR in July 
2025.

22. Section 3.6--Supplements to Environmental Impact Statements
    Section 3.6 concerns when a bureau must supplement an environmental 
impact statement. A supplement is required when ``a major Federal 
action remains to occur'' and the bureau makes substantial changes to 
the action or the bureau determines there are significant changed 
circumstances, in either case implicating environmental effects. DOI 
NEPA Handbook 3.6(a). Some comments took issue with the Handbook's use 
of the phrase ``remains to occur,'' preferring the phrase ``incomplete 
and ongoing,'' used in the CEQ's since-rescinded regulations. DOI 
disagrees with any suggestion that ``remains to occur'' is vague. 
Bureaus should have no trouble determining whether in the course of 
implementing a bureau action any ``major Federal action remains to 
occur.'' This approach is also consistent with long-standing provisions 
in the original CEQ regulations that required supplements only for 
``proposed actions''--that is, for actions that have not yet occurred 
but remain ``proposals'' or ``that stage in the development of an 
action when an agency subject to [NEPA] has a goal and is actively 
preparing to make a decision on one or more alternative means of 
accomplishing that goal and the effects can be meaningfully 
evaluated.'' See 40 CFR 1502.9(c) (1978) (rescinded); 40 CFR 1508.23 
(1978, defining ``proposal'') (rescinded).
    Some comments also took issue with the Handbook's treatment of 
public participation on supplements to an environmental impact 
statement. The Handbook provides that the Responsible Official may, but 
is not obliged to, circulate a supplement for public input ``as 
appropriate to the scope of the supplement and the proposed action.'' 
DOI NEPA Handbook 3.6(b). While those comments are specific to this 
section of the Handbook, they join many other comments addressed to 
DOI's approach to public participation in general. For a consolidated 
response to those comments, see Section III.E, infra.
    No changes have been made to this section relative to the version 
released with the IFR in July 2025.
23. Section 3.7--Integrity and Completeness of Information
    Section 3.7 expresses a preference for reliance on existing data 
and other information resources, directing bureaus to undertake new 
scientific or technical research only when ``the bureau anticipates 
that the results of that research will be essential to a reasoned 
choice among alternatives and the overall costs and time frame of such 
undertaking are not unreasonable.'' DOI NEPA Handbook 3.7(a). This 
approach is consistent with the original CEQ regulations, Congress 
codified this approach in the 2023 statutory amendments. See 40 CFR 
1502.22(a) (1978); 42 U.S.C. 4336(b)(3). New

[[Page 8746]]

research can be costly and time-consuming, and to make the NEPA process 
more efficient, bureaus should rely on existing sources of information 
wherever possible.
    Paragraph (b) of this section provides guidance to bureaus in 
situations where existing data or information is incomplete but cannot 
be reasonably obtained or developed at a reasonable cost. In such 
cases, again for efficiency's sake, the bureau should document the data 
or information gap and proceed with preparation of the environmental 
document. Some comments suggested that DOI should incorporate a 
provision akin to one in the CEQ regulations that agencies apply 
accepted scientific methods to resolve data gaps. As an initial matter, 
and as noted above, in developing its Handbook, DOI is implementing the 
statute, not simply standing in for CEQ's now-rescinded regulations, 
which are no longer in force. Section 3.7(b) is consistent with NEPA, 
and because the Handbook is designed to promote efficiency and 
certainty, DOI declines to make the change suggested by those comments.
    No changes, beyond one technical correction, have been made to this 
section relative to the version released with the IFR in July 2025.
24. Section 3.8--Integrating NEPA With Other Environmental Requirements
    Section 3.8 directs bureaus to combine NEPA analysis and 
environmental documents with other analysis processes and documentation 
associated with the proposed action at issue and provides guidance on 
how to do so. No changes, beyond one edit for clarity, have been made 
to this section relative to the version released with the IFR in July 
2025.
25. Section 3.9--Elimination of Duplication With State, Tribal, and 
Local Procedures
    Section 3.9 directs bureaus to coordinate NEPA analysis and the 
preparation of environmental documents with State, Tribal, and local 
agencies engaged in similar processes and provides guidance on how to 
do so. This section implements Congress's design in Section 107 as 
added by the 2023 statutory amendments. See, e.g., 42 U.S.C. 4336a(a), 
(b). No changes have been made to this section relative to the version 
released with the IFR in July 2025.
26. Section 3.10--Proposals for Regulations
    Section 3.10 directs bureaus to consider whether documents prepared 
in the course of rulemaking also may be used to satisfy NEPA with 
respect to that rulemaking and to rely on such documents when they are 
able. No changes have been made to this section relative to the version 
released with the IFR in July 2025.
27. Section 3.11--Unique Identification Numbers
    Section 3.11 addresses the practical concern of establishing a 
system by which relevant information and documents can be tracked in 
conjunction with one another. The requirement to coordinate use of 
identification numbers with CEQ is intended to support cross-agency 
coordination across multiple Federal agencies and navigation by the 
public of documents that support decisions made.
28. Section 3.12--Emergencies
    DOI elected to retain the provisions addressing NEPA compliance as 
related to emergencies in its NEPA regulations at 43 CFR 46.150; 
therefore, this section now consists primarily of cross-references to 
those provisions. See Section II.B.1, supra, for discussion of the 
relevant regulation.
29. Section 4.1--Decision Documents
    Section 4.1 provides direction to bureaus as to how and when to 
document and make public their decisions, in particular how the mode of 
complying with NEPA affects Department expectations and requirements 
for how decisions are documented. The section reiterates the bureaus' 
discretion to select any one or a blend of the alternatives considered 
in the course of the NEPA process. DOI has revised this section from 
the version released with the IFR in July 2025 to better clarify when a 
decision should be documented and when a decision should be published.
30. Section 4.2--Filing Requirements
    Section 4.2 provides guidance for filing environmental impact 
statements with the Environmental Protection Agency for publication and 
notification of availability. No changes, beyond one edit for clarity, 
have been made to this section relative to the version released with 
the IFR in July 2025.
31. Section 5.1--Procedures for Applicant-Prepared Environmental Impact 
Statements and Environmental Assessments
    Because procedures for applicant-prepared environmental documents 
are retained in regulation, this section of the Handbook consists only 
of a cross-reference. See Section II.B.3, supra, for discussion of the 
relevant regulation.
32. Section 5.2--Using a Bureau-Directed Contractor To Prepare 
Environmental Documents
    Because procedures for preparation of environmental documents by a 
bureau-directed contractor are retained in regulation, this section of 
the Handbook consists only of a cross-reference. See Section II.B.3, 
supra, for discussion of the relevant regulation.
33. Section 6.1--Definitions
    Section 6.1 defines the terms of art used throughout the Handbook. 
DOI has added definitions of the terms design features and 
environmental document to the definitions section since the Handbook 
was first published in July 2025 alongside the IFR. Other definitions 
have been revised for clarity in this updated version of the Handbook.
34. Section 7.1--Severability
    Section 7.1 consists of a statement of severability in the event 
one or more of the DOI NEPA procedures contained in the Handbook are 
found to be invalid.

III. Comments

    DOI received approximately 6,601 written submissions in response to 
the interim final rule. The overwhelming majority of comments 
(approximately 6,122) were in the form of two different letters that 
were identical or very similar in form and content. From among the 
6,601 comments, DOI received approximately 458 unique public comments, 
including from non-governmental organizations, State agencies, local 
and regional governments, Tribes, industry groups, members of the U.S. 
House of Representatives, and members of the public.
    DOI is providing summaries of and responses to those unique and 
substantive comments it received on the IFR in the following section of 
this final rule. The DOI received comments expressing general support 
for the IFR and comments expressing opposition to the IFR. None of the 
comments changed DOI's conclusion that it is appropriate to partially 
rescind and otherwise revise the previous regulations, though DOI made 
minor edits to those regulations upon further review. In addition, DOI 
made various edits to the Department of the Interior Handbook: National 
Environmental Policy Act Implementing Procedures (hereinafter, DOI NEPA 
Handbook) to correct or clarify procedural issues, or address internal 
or external comments. Responses to comments on the DOI NEPA Handbook 
are not addressed specifically in this section as revision and 
publication of

[[Page 8747]]

the DOI NEPA Handbook is not part of the rulemaking. However, DOI 
considered comments on the DOI NEPA Handbook when making revisions to 
that document, which is being reissued concurrently with this final 
rule, and as appropriate provides responses in the interest of clarity 
and ensuring public understanding of DOI's rationales. Further, the 
section-by-section discussion the DOI NEPA Handbook herein addresses, 
with particular focus, how concepts previously addressed in 43 CFR part 
46 now appear in the DOI NEPA Handbook. For example, defined terms used 
in this rule are found in the DOI NEPA Handbook, Section 6.1 
Definitions and, in several instances, are consistent with how they 
appeared in 43 CFR part 46, often, with more helpful detail. See, e.g., 
43 CFR 46.30 (definitions of ``Proposed Action'' and ``Responsible 
Official''; rescinded).

A. General Comments on the IFR

    Comment: Several commenters expressed support for the IFR. Letters 
of support commended the Department for updating its NEPA procedures to 
be consistent with E.O. 14154, aligning the NEPA implementing 
procedures with the FRA and the Supreme Court's decision in Seven 
County Infrastructure Coalition, and simplifying permitting procedures 
and the NEPA process.
    Response: DOI acknowledges these supportive comments.
    Comment: Many commenters expressed opposition to the IFR. Letters 
of opposition urged the Department to reverse course.
    Response: DOI acknowledges these opposing comments.
    Comment: One commenter expressed support for the new DOI NEPA 
Procedures and stated that it is imperative that DOI leadership ensure 
that bureaus implement these procedures and adapt their practices to 
conform to them.
    Response: The DOI NEPA procedures are part of a coordinated effort 
to reduce the burdens associated with NEPA compliance across the 
Federal Government and ensure that DOI bureaus comply with NEPA and DOI 
NEPA regulations. DOI acknowledges that additional guidance or training 
may be necessary to appropriately implement these revised DOI NEPA 
procedures.

B. Comments Regarding the Rulemaking Process

    Comment: Several commenters requested that DOI extend the comment 
period for the IFR.
    Response: DOI determined that 30 days was adequate because the 
scope of the IFR was limited to partial removal and minimal additions 
or revisions to the DOI regulations. While DOI made a greater number of 
revisions to the procedural provisions related to compliance with NEPA 
now present in the DOI NEPA Handbook, these changes, which are not part 
of this rulemaking, largely aligned DOI procedures with recent 
amendments to NEPA or developments in case law, such as the renewed 
focus in Seven County Infrastructure Coalition on limiting the scope of 
analysis to the reasonably foreseeable environmental effects of the 
agency's proposed action and reasonable alternatives. Moreover, DOI 
received more than 6,600 comments on its IFR, and the volume and 
substantive content of the comments indicates that the public had an 
adequate opportunity to comment.
    Comment: Several commenters requested that the IFR be published as 
a proposed rule with a period for public comment prior to the IFR's 
effective date.
    Response: The Administrative Procedure Act (APA) authorizes 
agencies to issue regulations without notice and public comment when 
the rule is an ``interpretative rule[ ], general statement[ ] of 
policy, or rule[ ] of agency . . . procedure[ ] or practice,'' 5 U.S.C. 
553(b)(A), or when an agency finds, for good cause, that notice and 
comment is ``impracticable, unnecessary, or contrary to the public 
interest,'' id. 553(b)(B). The APA did not require DOI to publish a 
notice of proposed rulemaking and consider public comments before the 
effective date of the rule because three separate exceptions to the 
APA's general requirement apply here: (1) the legacy DOI NEPA 
regulations were procedural only and did not dictate or preclude any 
DOI actions; rather, the legacy DOI NEPA regulations prescribed 
processes for DOI and its bureaus to follow when complying with NEPA; 
(2) the legacy DOI NEPA regulations merely provided an interpretation 
of a statute rather than making discretionary policy choices 
establishing enforceable rights or obligations for regulated parties; 
and (3) good cause exists to forgo notice-and-comment procedures and 
put the rule into immediate effect because public comment on the rule 
was and is unnecessary and impracticable. The legacy DOI NEPA 
regulations were expressly promulgated to supplement CEQ's NEPA 
regulations; following the vacatur and rescission of CEQ's NEPA 
regulations, DOI was left with vestigial NEPA regulations that 
``supplemented'' a CEQ regulatory regime that no longer existed. 5 
U.S.C. 553 (b)(A)-(B).

C. Comments on the IFR Process

    Comment: Several commenters disagreed that DOI had good cause to 
waive the APA notice-and-comment requirements imposed by 5 U.S.C. 
553(b). These commenters stated that DOI's IFR did not establish that 
notice and an opportunity to comment were unnecessary, impracticable, 
or contrary to the public interest. These commenters asserted that, 
rather than reducing confusion and supporting public interest, the IFR 
creates more confusion about how DOI will undertake its NEPA reviews. 
In addition, several commenters disagreed with DOI's conclusion that 
its rule to partially remove and revise its NEPA implementing 
regulations is an interpretative rule or, in the alternative, a rule of 
agency procedure that does not, in either case, require notice and 
comment.
    Response: DOI proceeded via IFR in response to E.O. 14154, which, 
among other things, revoked E.O. 11991, the E.O. in which President 
Carter had delegated authority to CEQ to promulgate regulations 
implementing NEPA and binding agencies in their implementation of NEPA; 
DOI's NEPA implementing regulations supplemented those CEQ regulations. 
Without E.O. 11991 and its Presidential delegation of authority, CEQ 
was obligated to rescind its NEPA implementing regulations and thus it 
was imperative for DOI to address supplementary regulations that were 
no longer consistent with CEQ direction. The APA did not require the 
Department to publish a notice of proposed rulemaking and consider 
public comments before the effective date of the rule because three 
separate exceptions to that requirement apply: (1) the legacy DOI NEPA 
regulations were procedural only and did not dictate or preclude any 
DOI actions; rather, the legacy DOI NEPA regulations prescribed 
processes for the Department and its bureaus to follow when complying 
with NEPA; (2) the legacy DOI NEPA regulations merely provided an 
interpretation of a statute rather than making discretionary policy 
choices establishing enforceable rights or obligations for regulated 
parties; and (3) good cause exists to forgo notice-and-comment 
procedures and put the rule into immediate effect because the legacy 
DOI NEPA regulations were expressly promulgated to supplement CEQ's 
NEPA regulations; following the vacatur and rescission of CEQ's NEPA 
regulations, the Department was left with vestigial NEPA regulations 
that ``supplemented'' a CEQ regulatory

[[Page 8748]]

regime that no longer existed. 5 U.S.C. 553 (b)(A)-(B).
    Moreover, DOI's IFR contained all the elements of a notice of 
proposed rulemaking as required by the APA. 5 U.S.C. 553(b); see also 
Little Sisters of the Poor Saints Peter & Paul Home v. Pennsylvania, 
591 U.S. 657 (2020). DOI explained its position with sufficient detail 
to put the public on notice that it was partially rescinding and 
otherwise revising its NEPA implementing regulations and provided its 
rationale along with an opportunity to comment. The public understood 
the action DOI was taking and took advantage of the opportunity to 
comment; DOI received more than 6,600 comments on its IFR. Thus, while 
DOI maintains for the reasons noted above that its IFR is subject to 
the exceptions set forth in 5 U.S.C. 553(b), this final rule represents 
the culmination of a process functionally equivalent to a traditional 
notice-and-comment rulemaking regardless of the initial procedural 
basis for the IFR.
    DOI is issuing this final rule to respond to comments on the IFR 
and explain that it is reaffirming its decision to partially remove and 
otherwise revise its NEPA implementing regulations, subject to the 
additional revisions made by this final rule. This final rule therefore 
supersedes the IFR. The public had the opportunity to comment prior to 
issuance of this final rule, thereby rendering comments objecting to 
the IFR process moot.
    Comment: Some Tribes and organizations representing Tribal 
interests requested formal government-to-government consultation 
regarding the IFR before it took effect. Commenters noted that there 
was no communication or notification of the IFR before publication. 
Some commenters disagreed with DOI's statement that the IFR does not 
require consultation with Tribal governments. Some commenters stated 
that the IFR incorrectly states that it is not a regulatory policy with 
Tribal implications. Several commenters note that the Federal 
Government has a duty to consult with Tribal Nations on Federal actions 
that may have Tribal implications, as expressed in E.O. 13175.
    Response: Changes to Federal agency NEPA compliance procedures do 
not implicate Tribal interests that would be the subject of government-
to-government consultation but pertain only to internal procedures for 
agencies to comply with NEPA, including their analysis of environmental 
impacts. The way in which agencies conduct analysis of the 
environmental impacts of proposed actions is independent of the way 
agencies engage in government-to-government consultation about proposed 
actions of interest to Tribes, and independent of the way agencies must 
comply with other laws and policies. Members of Tribes may always 
provide input into agency decision-making. Pursuant to E.O. 13175, 
Consultation and Coordination with Indian Tribal Governments (Nov. 6, 
2000), agencies must consult with Tribes before promulgating 
regulations with Tribal implications in certain instances, none of 
which are triggered here. Although DOI is not conducting government-to-
government consultation, it has considered the input from Tribal 
governments and organizations representing Tribal interests provided 
during the public comment period on the IFR, as reflected in this 
rulemaking. Neither the IFR nor this rulemaking alters DOI's duties 
towards Tribes.
    Comment: Several commenters stated that the IFR is not supported by 
adequate reasoning, particularly given the magnitude of change in DOI 
NEPA implementing procedures, and that E.O. 14154 does not justify the 
move from codified regulations to a handbook.
    Response: DOI explained that it revised its NEPA procedures to 
adjust for the fact that CEQ regulations no longer exist, conform these 
procedures to the 2023 statutory amendments, respond to President 
Trump's direction in E.O. 14154, and address the difficulties 
associated with the NEPA process and NEPA litigation identified by the 
Supreme Court in Seven County Infrastructure Coalition.
    DOI also provided more detailed explanation as to how the handful 
of provisions that will remain in regulation would operate, including 
by explaining the reasons to retain those provisions in regulation and 
for the targeted changes made to those provisions and how those changes 
are intended to be implemented. DOI is not required to provide the same 
kind of detail on the establishment of its internal guidance (i.e., the 
DOI NEPA Handbook), where the balance of its NEPA procedures now 
reside, but the agency nevertheless provided discussion of the DOI NEPA 
Handbook, and made it available for public comment along with the IFR. 
Further, the section-by-section discussion of the DOI NEPA Handbook 
herein addresses, with particular focus, how concepts that originally 
appeared in 43 CFR part 46 are now addressed in the DOI NEPA Handbook. 
And as DOI explained, it moved its procedures back to Departmental 
policy--where it appeared for decades prior to 2008--for the benefit of 
greater flexibility that it provides at this time given that NEPA is 
rapidly evolving as reflected in statutory amendments over the last 
several years.
    Comment: Several commenters requested that the Department recodify 
its NEPA regulations instead of providing guidance in the form of a 
handbook because the latter lacks the enforceability and consistency 
associated with codified regulations.
    Response: In response to both E.O. 14192, which requires reducing 
regulation, and E.O. 14154, which resulted in CEQ rescinding its NEPA 
regulations (40 CFR parts 1500 -1508), the Department reduced its NEPA 
regulations and consolidated DOI's NEPA procedures in the DOI NEPA 
Handbook. Those changes reflect DOI's reasoned judgment as to how best 
to provide for the implementation of NEPA, including in light of recent 
amendments to and judicial interpretations of NEPA as a ``purely 
procedural statute.'' Further, as noted above, this return of the DOI 
NEPA procedures from primarily in regulations to primarily in 
Departmental policy--where it appeared for decades prior to 2008--
supports the Departmental goals of flexibility in a changing legal 
landscape.

D. Comments on the Consequences of the IFR

    Comment: Some commenters stated that the new DOI NEPA procedures 
will result in increased litigation and delays. Some comments warned 
that the IFR could lead to regulatory questions because there are no 
codified procedures and project sponsors may face conflicting standards 
due to a combination of regulatory decentralization, legal shifts, and 
procedural ambiguity in the DOI NEPA procedures. These commenters 
further assert that the new DOI NEPA procedures will result in 
deficient records that may need to be supplemented in litigation or as 
part of later site-specific actions.
    Response: Though these asserted harms are speculative, DOI did 
consider previous litigation and judicial precedents in revising the 
DOI NEPA procedures, most particularly in moving many of these 
procedural provisions from regulation back to Departmental policy 
documents. Procedural rules have always been subject to change without 
notice and comment. And even if (and to the extent that) DOI's NEPA 
regulations are deemed to be interpretive rather than procedural, 
notice-and-comment procedures are not required for interpretive 
rulemaking, regardless of whether they were

[[Page 8749]]

originally promulgated with notice and comment. See 5 U.S.C. 553(b)(A); 
Perez v. Mortgage Bankers Ass'n, 575 U.S. 92 (2015). DOI provided 
notice of the DOI NEPA procedure revisions, and the announcement of the 
IFR explicitly allows for previously initiated NEPA reviews to proceed 
under the previous NEPA procedures as expressed in the 2008 DOI NEPA 
regulations when appropriate. Additionally, DOI disagrees with 
commenters' assertions that the flexibilities and efficiencies secured 
in the new DOI procedures will detract from DOI's ability to assemble 
sufficient administrative records or otherwise exacerbate litigation 
risk. The basis for DOI's new procedures is the statute as amended, the 
implementation of President Trump's policy direction in E.O. 14154 
section 5 as consistent with applicable law, and the Supreme Court's 
recent, landmark Seven County opinion. DOI is confident that NEPA 
implementing procedures shaped under the guidance of these three 
pillars will produce legally durable NEPA analyses that are sound as a 
matter of policy.
    Comment: Several commenters raised concerns that the changes to the 
DOI NEPA procedures would potentially cause conflict with State laws, 
including third-party compliance with State environmental review 
requirements. One commenter stated the revised DOI NEPA procedures 
result in an increased burden on States to evaluate impacts of Federal 
actions.
    Response: With respect to State interests in maintaining DOI's NEPA 
implementing procedures in regulation, the removal and revisions do not 
change the statutory mandate for agencies to ensure a coordinated 
environmental review process with the States. See 42 U.S.C. 4332(2)(C), 
4332(2)(G), 4332(2)(J), 4334, and 4336a. State obligations and 
authorities related to the evaluation of Federal actions are unchanged 
by the revision of the DOI NEPA procedures--much less by their return 
from a regulatory to a Departmental policy format.
    Comment: Several commenters noted differences between DOI's NEPA 
procedures and those of other Federal agencies that issued NEPA 
procedures concurrently and requested more consistency or expressed 
preferences regarding aspects of the NEPA procedures. Some of the 
preferences noted included maintaining previous DOI NEPA procedure 
regulatory text or revising remaining DOI NEPA procedure regulatory 
text or guidance. For example, several commenters suggested that DOI 
adopt NEPA procedures used by other agencies, such as the U.S. 
Department of Agriculture extraordinary circumstances review protocol 
for reliance on categorical exclusions.
    Response: DOI carefully considered revisions to its NEPA procedures 
based on the experience of its bureaus and believes the changes, with 
the edits made in this final rule and the revisions to the DOI NEPA 
Handbook, provide for both consistency and increased effectiveness in 
DOI decision-making for its mission and programs. CEQ, including 
through the working group created by E.O. 14154, is coordinating the 
revision of Federal agency-level implementing procedures for 
consistency. This is in keeping with Congress's direction that agencies 
consult with CEQ when developing their procedures for implementing 
NEPA, see 42 U.S.C. 4332(2)(B).
    Comment: Several commenters stated that DOI failed to provide a 
reasoned explanation for the decision to largely rescind its NEPA 
regulations in favor of establishing the DOI NEPA Handbook.
    Response: As explained in the IFR and this final rule, NEPA ``is a 
purely procedural statute'' that covers internal processes, Seven 
County Infrastructure Coalition, 605 U.S. at 173, and DOI's 
implementation of that procedural statute need not be in regulation. 
And, as explained above, DOI's legacy regulations were procedural 
only--those regulations merely described processes for DOI and its 
bureaus to follow when complying with NEPA. Many Federal agencies do 
not have NEPA procedures in regulation, just as DOI did not have its 
NEPA procedures in regulation before 2008, and agencies have discretion 
to determine the form of their NEPA procedures for effective NEPA 
implementation. DOI finds the benefit of greater flexibility that 
guidance provides appropriate at this time given that NEPA is rapidly 
evolving as reflected in statutory amendments over the last several 
years.
    Comment: Several commenters asserted that DOI failed to adequately 
explain its departure from CEQ's rescinded regulations and policy 
positions. These comments suggest that DOI is required to acknowledge 
CEQ's earlier positions, identify with specificity where DOI's 
regulations and NEPA Handbook differ from them, and justify those 
differences in light of CEQ's prior interpretations of NEPA or retain 
CEQ's regulations.
    Response: As explained in greater detail above, DOI acknowledges 
that CEQ's regulations previously provided a framework for NEPA 
compliance and informed agency practices. However, as CEQ explained in 
its final rule affirming the removal of its regulations, CEQ lacks 
independent statutory authority to maintain NEPA implementing 
regulations that bind agencies in the absence of an executive order 
delegating rulemaking authority to CEQ. 91 FR at 622-23; see also 
Executive Order 14154, Unleashing American Energy, 90 FR 8,353. 
Accordingly, agencies may now exercise discretion to adopt procedures 
consistent with NEPA and executive policies. Indeed, as DOI explained 
in its IFR, because DOI's prior NEPA implementing procedures were 
expressly designed as a supplement to CEQ's rescinded regulations, 
CEQ's recission necessitated that DOI adopt new procedures designed to 
independently implement NEPA.
    While some commenters evaluated DOI's NEPA implementing procedures 
against CEQ's prior regulations, DOI does not consider the adoption of 
its new procedures to be a departure from DOI's own prior policy simply 
because CEQ may in the past have expressed a different view on a given 
point of NEPA implementation. DOI's primary foundation for the updates 
to its NEPA procedures, as explained above, is the statute and Supreme 
Court precedent. Instead of seeking to carry forward or build upon 
CEQ's repealed procedures, DOI focused on developing NEPA procedures to 
meet the statutory requirements found in 42 U.S.C. 4321-4347. DOI 
disagrees that it must retain elements of the former CEQ regulations 
simply because CEQ in its rescinded regulatory regime included those 
elements and provided some rationale for so doing. CEQ's regulations no 
longer govern agency compliance, and the relevant question is whether 
DOI's procedures satisfy NEPA's requirements. As explained in this 
rulemaking, DOI has determined, after consultation with CEQ and 
consideration of comments received, that procedures adopted here as 
final satisfy NEPA's requirements and DOI's other statutory 
responsibilities. DOI's updated NEPA procedures appropriately account 
for DOI's specific authorities and activities, the environmental 
effects it typically encounters, and the need for timely and efficient 
decision-making, as well as for significant changes in law since DOI 
established its prior regulations. Nevertheless, where relevant and 
appropriate, this preamble to the final rule addresses aspects of DOI's 
NEPA procedures that follow or depart from aspects of CEQ's prior 
approach.
    Comment: Some comments noted that DOI did not explain how its 
approach to implementing NEPA compared to approaches adopted by other 
agencies. For example, commenters raised issue

[[Page 8750]]

with DOI using a non-codified handbook to implement NEPA, where 
differently some agencies codified some or all of their NEPA 
implementing regulations.
    Response: DOI recognizes that its approach to implementing NEPA may 
differ from other agencies' approaches to implementing NEPA. Through 
issuance of this final rulemaking and NEPA Handbook, DOI has determined 
the best position for DOI to establish NEPA implementing procedures 
that fit its programs and authorities. Following the removal of CEQ's 
NEPA regulations, DOI has flexibility to determine agency-specific NEPA 
procedures to modernize, simplify, and accelerate NEPA reviews and 
support responsible development.
    Furthermore, DOI notes that NEPA requires agencies to consult with 
CEQ when developing agency NEPA procedures. See 42 U.S.C. 4332(2)(B). 
NEPA does not require agencies to coordinate with one another to ensure 
identicality between their respective NEPA procedures, let alone 
between the means by which each agency issues those procedures. 
Agencies' statutory authorities and subject-matter expertise differ 
greatly, and variance on these matters is to be expected. Indeed, 
agencies' NEPA procedures were not homogenous or identical during the 
era in which CEQ maintained overarching implementing regulations, and 
there is no requirement or reasonable expectation that they should be 
so once those CEQ regulations have been vacated and rescinded.
    Comment: Some commenters, citing a 2025 CEQ report from the 
previous administration, take the position that the data do not support 
the need to implement measures to shorten timelines for the completion 
of environmental assessments and environmental impact statements. At 
least one commenter claims that trends towards longer timelines had 
been reversed by the policies of the previous administration.
    Response: DOI has concluded that further measures are necessary to 
meet the statutory requirements of NEPA and the policies set forth in 
E.O. 14154. As part of the FRA, Congress amended NEPA to add mandatory 
deadlines and related procedural reforms for the development of 
environmental assessments and environmental impact statements. 42 
U.S.C. 4336a(g). Specifically, Congress identified certain triggering 
events and directed agencies to complete environmental assessments and 
environmental impact statements within one and two years, respectively, 
of those events. Id. To enforce these deadlines, Congress provided 
project sponsors with a cause of action to seek judicial review of an 
agency's failure to act by the deadline. Id. 4336a(g)(3).
    The 2025 CEQ report on which commenters rely compared median 
timelines for environmental impact statements completed from 2013 to 
2016 (3.5 years), 2017 to 2020 (3.1 years) and 2021 to 2024 (2.4 
years). CEQ, Environmental Impact Statement Timelines (2010-2024), at 4 
(Jan. 13, 2025). Though CEQ noted the general downward trend in the 
amount of time taken to prepare environmental impact statements, it did 
not evaluate how fewer statements being completed over the periods it 
analyzed may have contributed to this trend: 2013 to 2016 (621 
statements); 2017 to 2020 (436 statements); and 2021 and 2024 (232 
statements). For example, CEQ did not assess whether the decline from a 
median of 3.1 years (2017-2020) to 2.4 years (2021-2024), a 22.6 
percent decrease, could be attributed to a 46.8 percent decline in 
total statements completed. Similarly, CEQ did not assess whether 
Federal resources available for completing environmental reviews 
changed over these periods. CEQ also declined to analyze average 
timelines over these same periods, relegating those averages from 2010 
to 2024 to a simple chart. But the report's accompanying spreadsheet 
estimates that environmental impact statements were completed in 4.1 
years on average from 2010 to 2024.
    Even assuming CEQ's characterizations were accurate, the report 
states that environmental impact statements were not completed within 
the statutorily required two-year period when measured by the median of 
completed statements. CEQ's data shows that agencies, without more 
fundamental reform, would not achieve compliance with the statute as 
amended. Commenters have not provided a basis for DOI to alter its view 
that the reforms in the IFR as finalized in this final rule are an 
appropriate means to accomplish compliance with NEPA and the policies 
of the United States. Regardless, DOI concludes that CEQ's 2025 report 
is flawed. An equally plausible explanation for its data is the large 
reduction in output, i.e., fewer environmental impact statements. DOI 
notes that the Inflation Reduction Act also provided hundreds of 
millions of dollars above baseline Federal spending for expediting and 
improving environmental reviews during the 2021 to 2024 period. Public 
Law 117-169. DOI cannot rely on CEQ's prior conclusions about the 
reasons for the downward trend in time needed to complete environmental 
impact statements when alternative explanations for those conclusions 
were plainly ignored.\1\ Moreover, DOI cannot rely on CEQ's report 
where the fundamental conditions are reversed. This administration's 
policies are designed to increase output and demand energetic, 
efficient responses to a declared energy emergency, see E.O. 14156, 
Declaring a National Energy Emergency, 90 Fed Reg. 8,433 (Jan. 29, 
2025); see also Continuation of the National Emergency With Respect to 
Energy, 91 FR 1,667 (Jan. 14, 2026), and related Executive Orders. See, 
e.g., E.O. 14154, Unleashing American Energy, 90 FR 8,353.
---------------------------------------------------------------------------

    \1\ DOI acknowledges that it relies in part on the 2025 CEQ 
report in the regulatory impact analysis (RIA) accompanying this 
action. DOI did so because that study is a recent attempt to provide 
EIS timeline data, and it specifically includes data on EISs issued 
by DOI bureaus. While DOI has employed the study for purposes of RIA 
analysis in this regard, we explain here in this final rule why the 
study does not bear the weight commenters place on it as a matter of 
policy.
---------------------------------------------------------------------------

E. Comments on DOI-Specific NEPA Procedures

    Comment: Some commenters expressed concerns and proposed edits or 
text changes to the DOI NEPA procedures to provide clarity or address 
their specific concerns.
    Response: DOI has considered comments and, in some cases, where DOI 
agrees with the commenter, has made edits to either the regulatory text 
in the final rule or to the DOI NEPA Handbook. Regulatory text changes 
in the final rule are non-substantive changes from the IFR and 
described in Section II above. Text changes to the DOI NEPA Handbook 
that is reissued concurrently with the final rule reflect both 
substantive and editorial revisions to address corrections or provide 
clarity.
    Comment: Many commenters expressed concerns about removing NEPA 
procedures from regulation, which often include notice-and-comment 
rulemaking, and one commenter ``cautions against moving entirely to 
guidance documents rather than notice-and-comment rulemaking.''
    Response: From soon after the enactment of NEPA in 1970 through 
2008, the DOI NEPA procedures appeared solely in guidance. This 
procedural guidance was subject to notice-and-comment requirements only 
by virtue of CEQ regulations that have now been rescinded. See 43 Fed 
Reg. 55,978, 56,003 (Nov. 29, 1978) (promulgation of CEQ's NEPA 
implementing regulations, directing agencies to publish their proposed 
procedures for comment); 91 FR 618 (Jan. 8, 2026) (final rule adopting

[[Page 8751]]

interim final rule rescinding CEQ's NEPA implementing regulations). 
Contrast 42 U.S.C. 102(2)(B) (Congressional direction to agencies to 
``develop methods and procedures'' in consultation with CEQ to 
implement NEPA, with no notice-and-comment requirement). As the 
procedural guidance is binding only on the DOI bureaus themselves, it 
is guidance that does not need to be in regulation or be subject to 
notice-and-comment requirements for rulemakings under the APA. And as 
explained above, DOI finds the benefit of greater flexibility that 
guidance provides appropriate at this time given that NEPA is rapidly 
evolving as reflected in statutory amendments over the last several 
years.
    Comment: Many commenters expressed concerns that all cooperating 
agency provisions were removed from regulation, stating that durability 
and consistency is provided when these provisions are codified in 
regulation. One commenter stated, ``[NEPA] reflect[s] a deliberate 
congressional commitment to cooperative federalism. The IFR[ ] should 
be revised to reflect the full breadth of this mandate by reinstating 
clearly defined, enforceable provisions for engaging cooperating 
agencies . . . .''
    Response: In response to these and other comments, and to better 
implement the statutory requirement for lead agencies to coordinate 
with them, 42 U.S.C. 4336a(a) and (b), DOI has reinserted modified 
regulations for the designation of lead agencies and the selection of 
cooperating agencies at 43 CFR 46.220 and 46.225, respectively. Because 
DOI recognizes the unique and special role that cooperating agencies, 
as representatives of sovereign governments, have in the Federal NEPA 
process, and because Congress has specifically provided a mechanism in 
statute for these government agencies to participate under appropriate 
circumstances in the cooperating agency process, DOI has elected to 
transfer the procedures governing that process from the DOI NEPA 
Handbook to the Code of Federal Regulations.
    Comment: One commenter proposed edits to the DOI NEPA Handbook that 
would require all eligible governmental entities be approved as 
cooperating agencies and would eliminate the bureaus' discretion to 
deny requests by eligible agencies for cooperating agency status.
    Response: DOI is declining to restrict the discretion to consider 
whether to approve requests for cooperating agency status granted to 
lead agencies by NEPA in section 107(a)(3)(B), 42 U.S.C. 
4336a(a)(3)(B). Such requests cannot be arbitrarily denied under the 
DOI NEPA procedures. See 43 CFR 46.225(c).
    Comment: Commenters raised concerns regarding public participation 
in NEPA processes and that the revised DOI NEPA procedures alter the 
long-standing, but now-abrogated, opportunities for public 
participation, for example by not requiring public comment with the 
issuance of a draft environmental impact statement, and that in light 
of the benefits to the agency from public comment periods and other 
forms of public participation, the reasoning to support that change was 
inadequate and arbitrary. Additionally, some commenters asserted that 
DOI has not sufficiently explained why it is not practicable for its 
NEPA procedures to impose across-the-board requirements that DOI 
solicit comment beyond those stages in the NEPA process that Congress 
has mandated.
    Response: The updates to DOI's NEPA public participation 
procedures, including in the final rule, mirror what NEPA requires. As 
discussed above, in the past, CEQ's NEPA regulations substantially 
guided and informed the content of DOI's NEPA procedures. CEQ's NEPA 
regulations, in all their iterations dating back to 1978, included 
procedural requirements that exceed those required by the statute. With 
respect to public participation in particular, CEQ's regulations 
historically included comment periods that the statute does not compel. 
For example, CEQ's 1978 regulations directed agencies to prepare 
environmental impact statements ``in two stages,'' 40 CFR 1502.9 
(1978), which included circulation of a draft environmental impact 
statement for public review and comment. 40 CFR 1503.1(a)(4) (1978).
    CEQ's NEPA regulations have now been rescinded by CEQ, Removal of 
National Environmental Policy Act Implementation Regulations, 91 FR 618 
(Jan. 8, 2026). In response, DOI developed its own updated NEPA 
regulations and other NEPA procedures, implementing the President's 
direction in E.O. 14154, Unleashing American Energy, 90 FR 8353, and 
E.O. 14192, Unleashing Prosperity Through Deregulation, 90 FR 9065 
(Feb. 6, 2025), to ensure that regulatory requirements are grounded in 
applicable law and to alleviate any unnecessary regulatory burdens. In 
doing so, DOI considered the appropriate scope of its public 
participation processes, including whether to define these processes in 
regulation or by guidance. Having elected to proceed by guidance to 
allow for greater flexibility to engage in the appropriate mode and 
extent of public participation on a case-by-case basis, DOI designed 
the DOI NEPA Handbook that replaces the repealed regulations to reflect 
the statute's requirements.
    NEPA, as amended by the Fiscal Responsibility Act of 2023, requires 
agencies to take public comment in only one specific circumstance: when 
agencies issue a notice of intent to prepare an environmental impact 
statement. See 42 U.S.C. 4336a(c). This requirement is fully 
incorporated into DOI's updated NEPA procedures, which provide, for 
example, that when a bureau intends to prepare an environmental impact 
statement, the bureau must publish a notice of intent to prepare an 
environmental impact statement in the Federal Register. DOI NEPA 
Handbook 1.8(b). Consistent with the statute, the DOI procedures 
specify that a notice of intent to prepare an environmental impact 
statement shall include ``a request for public comment on alternatives 
or effects and on relevant information, studies, or analyses with 
respect to the proposed agency action.'' DOI NEPA Handbook 1.8(b)(1).
    In developing its regulations and NEPA Handbook, DOI elected not to 
create new and additional public participation requirements that are 
not grounded in applicable law and which would result in unnecessary 
regulatory burdens. DOI was also mindful that NEPA, as amended by the 
Fiscal Responsibility Act, now includes statutory deadlines that 
agencies must meet. See 42 U.S.C. 4336a(g)(1) (establishing a two-year 
deadline to prepare environmental impact statements and a one-year 
deadline to prepare environmental assessments). Mandating a comment 
period for all environmental impact statements and environmental 
assessments would not only go beyond statutory requirements but could 
be in tension with DOI's statutory obligation to meet these deadlines.
    Though it need not have done so, DOI has established in its NEPA 
procedures that when a DOI bureau intends to prepare an environmental 
impact statement, the bureau must publish a Federal Register notice of 
such intent. DOI NEPA Handbook 1.8(b). And while a bureau intending to 
prepare an environmental assessment may publish a notice of intent to 
prepare an environmental assessment, it need not do so. DOI NEPA 
Handbook 1.8(b). In this respect, the DOI NEPA Procedures are 
consistent with long-standing flexibility regarding whether and how an 
agency involves the public when preparing an environmental assessment, 
as expressed in both the 1978 CEQ regulations and the 2008 DOI NEPA

[[Page 8752]]

regulations. See 40 CFR 1506.6(a) (requiring only ``diligent efforts''; 
rescinded); 43 CFR 46.305 (requiring bureaus to provide for public 
notification and public involvement when an environmental assessment is 
being prepared only ``to the extent practicable''; rescinded). That is, 
pre-decisional public involvement when a bureau was preparing an 
environmental assessment was never guaranteed. While DOI has considered 
and agrees with comments describing how the agency decision-making 
process can be improved by public comments and other forms of public 
participation, Congress has not elected to make pre-decisional public 
involvement a requirement. Crucially, however, the fact that DOI's NEPA 
procedures no longer prescribe a particular public comment process or 
period over and above what NEPA requires--apart from the DOI decision 
to require bureaus to publish a notice of intent in the Federal 
Register that invites comment when intending to prepare an 
environmental impact statement--does not prevent DOI bureaus from 
exercising their discretion to solicit additional public comment when 
they determine that doing so would be appropriate or helpful. Indeed, 
since publication of the IFR and DOI NEPA Handbook, DOI bureaus have 
regularly sought public comment on draft or preliminary NEPA documents. 
They have voluntarily elected to do so in a variety of contexts, 
including inviting public comment on certain environmental assessments 
for forestry and timber actions, see, e.g., the Outlaw Ridge Timber 
Management Project, DOI-BLM-ORWA-N010-2025-0011-EA (BLM Cascades Field 
Office, Oregon); fluid mineral development, see, e.g., Hazel Inez Multi 
Well Project, DOI-BLM-NM-P020-2026-0287-EA (BLM Carlsbad Field Office, 
New Mexico); road maintenance, see, e.g., Yellowstone National Park, 
North Entrance Road Reconstruction Project EA, PEPC 115825 (NPS January 
2026); habitat conservation plans, see, e.g., Environmental Assessment 
of a Proposed Habitat Conservation Plan and Incidental Take Permit for 
the Dunes Sagebrush Lizard (Sceloporus arenicolus) in New Mexico, FWS-
R2-ES-2025-0053-0002 (FWS December 2025); and recreation and visitor 
services. See Grand Teton National Park, Reimagining the Taggart Lake 
Experience, PEPC 119939 (NPS August 2025); SR9 Campground Management, 
DOI-BLM-UT-C030-2025-0019-EA (BLM St. George Field Office, Utah). 
Finally, although it should go without saying, what NEPA may or may not 
require regarding public involvement does not change what other 
statutes might require; agencies must comply with the provisions of all 
statutes applicable to their actions.
    Additionally, DOI notes that commenters specifically cite section 
2(b) of E.O. 11514, 35 FR 4247 (March 7, 1970), President Nixon's 
initial executive order regarding implementation of NEPA following the 
Act's original passage, in which President Nixon provided that agency 
NEPA implementing procedures ``shall include, whenever appropriate, 
providing for public hearings.'' In this regard, President Trump's E.O. 
14154 at section 2(b) provides that it is the policy of the United 
States that agencies ``provide opportunity for public comment.'' DOI 
notes that this provision of 14154 is not specifically directed towards 
NEPA implementation, but rather is contained in the introductory policy 
section of the Executive Order, which addresses the national interest 
in affordable and reliable energy and natural resources. President 
Nixon's Executive Order, which is specifically directed towards NEPA 
implementation, also specifically provides that agency NEPA procedures 
shall provide public hearings ``whenever appropriate'' and ``the 
fullest practicable'' provision of public information.
    DOI's view is that the NEPA implementing procedures it adopted via 
the summer 2025 IFR and Handbook, and this final rule and Handbook, 
constitute an appropriate execution of the policy direction in these 
two Executive Orders. Specifically: given both Congress's imposition of 
deadlines in the 2023 statutory amendments to NEPA and President 
Trump's specific direction with respect to permitting reform in E.O. 
14154 section 5 that, consistent with applicable law, efficiency be 
prioritized over other policy values; and mindful that President 
Nixon's Executive Order both predated the 2023 statutory amendments and 
President Trump's Executive Order; and furthermore that President 
Nixon's Executive Order conditioned its references to public engagement 
with the qualifier that they be ``practicable''; DOI's view is that its 
NEPA implementing procedures are consistent with these Executive Orders 
because they provide for public comment where Congress has directed all 
agencies to do so under NEPA, and, as explained elsewhere in this 
document, that DOI has and will continue to exercise its discretion to 
solicit additional public comment when it determines that doing so 
would be appropriate or helpful.
    Comment: Some commenters asserted that public participation is 
central to NEPA and that DOI is required to invite and respond to 
comments on draft environmental documents.
    Response: DOI disagrees that NEPA requires it prepare draft 
environmental documents and solicit public comment on each one. Before 
the FRA amendments to NEPA, the statute contained no requirement to 
solicit public comment at any stage in the NEPA process. As discussed 
in Section I.A., supra, NEPA's only reference to public review of an 
agency's environmental document stated that ``[c]opies of [the 
environmental impact statement] and the comments and views of the 
appropriate Federal, State, and local agencies . . . shall be made 
available . . . to the public as provided by section 552 of title 5,'' 
also known as FOIA. 42 U.S.C. 4332(2)(C). Nonetheless, even this 
provision does not contemplate solicitation of public comment; it 
merely speaks of the public's ability to view an environmental impact 
statement and comments submitted by certain governmental agencies.
    CEQ's prior regulations generally required, in relevant part, that 
agencies prepare and provide members of the public an opportunity to 
comment on a draft environmental impact statement. 40 CFR 1503.1 (1978) 
(rescinded). However, Congress comprehensively amended NEPA in the FRA 
to provide more prescriptive instructions to agencies on completing 
timely and unified Federal NEPA reviews. 42 U.S.C. 4336a. Specifically, 
Congress expressly provided for public comment for the first time, at 
one and only one step of the process for developing an environmental 
document: when an agency issues a notice of intent to prepare an 
environmental impact statement, it must invite public comment on that 
notice regarding ``alternatives or impacts and on relevant information, 
studies, or analyses with respect to the proposed agency action.'' 40 
U.S.C. 4336a(c). Congress retained the original obligation to make the 
environmental impact statement available through FOIA.
    Congress elected to require public comment only at the notice of 
intent stage in the NEPA process. DOI's view is that comment at the 
notice of intent stage is unique: It provides an opportunity for fact-
gathering from persons who may have relevant (indeed, unique) 
information about environmental conditions of land they live on or by 
with respect to projects that the bureau has determined will have a 
significant effect on the

[[Page 8753]]

environment. It makes sense that Congress required solicitation of 
public comment on all notices of intent to prepare an environmental 
impact statement, while imposing no such requirement with respect to an 
environmental assessment, both because Congress imposed a shorter 
deadline for agencies to develop an environmental assessment than to 
develop an environmental impact statement and because an environmental 
assessment, by definition, is typically prepared only for proposed 
actions that do not have reasonably foreseeable significant 
environmental effects. Accordingly, Congress intended that government 
and public resources should focus on developing and facilitating public 
engagement on matters considered in environmental impact statements. 
DOI's revised regulations reflect this statutory structure.
    DOI's NEPA procedures are thus consistent with Congress's 
instruction to provide an opportunity for members of the public to 
comment on the notice of intent to prepare an environmental impact 
statement. DOI will continue to make its environmental documents 
available to the public consistent with FOIA, and this requirement is 
not affected by this rulemaking. DOI otherwise maintains discretion to 
offer opportunities for public comment on draft environmental documents 
as appropriate.
    Comment: Commenters assert that DOI must independently justify the 
removal of certain public participation procedures, having acknowledged 
the importance of public engagement in the NEPA process during the 
rulemaking in which it codified in regulation its NEPA implementing 
procedures in 2008. Specifically, a commenter stated that the removal 
of consensus-based management from DOI regulations requires independent 
justification.
    Response: As explained elsewhere in this document, DOI continues to 
believe that public engagement is an important part of the NEPA 
process, where Congress has seen fit to require it, or in those cases 
in which it would be helpful and appropriate. As noted elsewhere in 
this notice, after DOI revised its NEPA implementing process in the 
IFR, it has elected to take comment in multiple NEPA reviews where its 
revised procedures did not impose such obligation. Consensus-based 
management was never a requirement of NEPA; it was a policy preference 
toward documenting public input in a certain way during the NEPA 
process. Members of the public have always been able to suggest 
reasonable alternatives for analysis to Federal agencies and remain 
able to do so. As agencies are required to evaluate a reasonable range 
of alternatives, the agencies must necessarily evaluate reasonable 
alternatives presented by the public if not already considered.
    Comment: Some commenters argued that DOI, rather than adopting the 
NEPA implementing procedures that it adopted in the summer of 2025 IFR, 
should instead have adopted some or all of the provisions of one or 
more of CEQ's now-rescinded NEPA regulations.
    Response: As DOI explains elsewhere in this document, the DOI NEPA 
procedures as adopted in the summer 2025 IFR and this final rule are 
not simply a subsequent iteration of the policies previously contained 
in CEQ's now-rescinded regulations, or a direct successor to them, but 
rather draw upon and implement the requirements of NEPA itself. DOI 
explained in the IFR and explains further in this final rule why it has 
adopted the NEPA implementing procedures that it has adopted, some 
aspects of which are the same as those in CEQ's now-rescinded 
regulations and others of which differ. It would not have been 
appropriate for DOI to more generally adopt CEQ's regulations, which 
were the product of and based on an Executive Order granting CEQ 
regulatory authority that has now been rescinded, and of which all but 
the 2024 rule did not have the benefit of Congress's major overhaul of 
NEPA in 2023; even with respect to the 2024 CEQ rulemaking, that 
rulemaking did not have the benefit of the Supreme Court's major, 
recent Seven County opinion, which instructed agencies, lower courts, 
and the general public that NEPA's effects analysis properly operates 
in a manner much different than that which formed the basis of the 2024 
rule.
    Comment: Various commenters asserted that the removal of 
regulations would affect environmental reviews of proposed actions, and 
would result in unexamined, unaddressed, and unmitigated impacts, 
specifically those related to climate change, environmental justice, 
and cumulative impacts. Commenters also asserted that DOI did not 
explain its decision to remove references to concepts such as ``direct 
effects,'' ``indirect effects,'' ``cumulative effects,'' 
``environmental justice concerns,'' and ``climate-change-related 
effects.''
    Response: First, as explained elsewhere in this preamble, the 
return of DOI's NEPA procedures from regulation to Departmental policy 
format does not, itself, change the procedural requirements of NEPA 
compliance for DOI's bureaus. The statute itself sets forth the 
framework of those procedural requirements and DOI's NEPA procedures, 
however formatted, merely elaborate upon that framework, hewing as 
closely as possible to the statutory provisions. Second, NEPA does not 
contain any provisions addressing any specific type of environmental 
impact. Direction from within the executive branch may in the past have 
pushed agencies to articulate environmental analysis according to 
artificial distinctions between ``direct,'' ``indirect,'' and 
``cumulative'' types of effects, or to place special emphasis upon 
certain categories of effects (i.e., ``climate change,'' 
``environmental justice''), but that direction has now been rescinded. 
See 91 FR 618 (Jan. 8, 2026) (final rule rescinding CEQ's NEPA 
regulations); Executive Order 14173, Ending Illegal Discrimination and 
Restoring Merit-Based Opportunity (Jan. 21, 2025) (revoking Executive 
Order 12898, Federal Actions to Address Environmental Justice in 
Minority Populations and Low-Income Populations; Executive Order 14154, 
Unleashing American Energy, 90 FR 8353 (Jan. 20, 2025) (revoking 
Executive Order 14096, Revitalizing Our Nation's Commitment to 
Environmental Justice for All). In other words, the distinctions and 
concepts identified by commenters do not exist in statute and were 
conceptual creations of CEQ, agencies, and courts to formulate analysis 
and guide agency decision-making.
    Instead of formulating the evaluation of environmental effects of 
bureau action using the artificial devices of ``direct,'' ``indirect,'' 
and ``cumulative'' effects that do not appear in the statute, DOI's 
NEPA procedures focus on the underlying principle of what constitutes 
an ``effect.'' In reorienting the focus of its procedures, DOI does not 
change or purport to change the scope of effects that DOI bureaus are 
required by statute to consider. Both before and after the updates to 
DOI's NEPA procedures, DOI bureaus were and are required to consider 
effects that are both reasonably foreseeable and have a reasonably 
close causal relationship to their proposed actions, each including a 
reasonable range of action alternatives, consistent with the statute, 
as clarified by the Supreme Court in Public Citizen and Seven County 
Infrastructure Coalition. Additionally, in light of Supreme Court's 
decision in Seven County Infrastructure Coalition, DOI elected to 
update its procedures to reflect the phrasing provided by the Supreme 
Court regarding effects. That is, ``agencies may, but are not required 
to, analyze environmental effects from

[[Page 8754]]

other projects separate in time, or separate in place, or that fall 
outside of the bureau's regulatory authority, or that would have to be 
initiated by a third party. If the bureau determines that such analysis 
would assist it in reasoned decision-making regarding the proposed 
action, it will document this determination in the environmental 
assessment and explain where it drew a reasonable and manageable line 
relating to the consideration of such effects from such separate 
projects.'' DOI NEPA Handbook 1.5(c). ``Similarly, the bureau will 
document in the environmental assessment where and how it drew a 
reasonable and manageable line relating to its consideration of any 
environmental effects from the proposed action that extend outside the 
geographical territory of the project or might materialize later in 
time.'' Id. (citing Seven County Infrastructure Coalition, 605 U.S. 
168). This language, adapted directly from Seven County Infrastructure 
Coalition, provides DOI with direction on how to consider, as 
appropriate, the environmental consequences of bureau action that may 
previously been expressed in concepts such as ``indirect effects'' and 
``cumulative effects.'' This focus on the meaning of ``effect'' has led 
DOI to restore in large part the concept of ``connected action'' to the 
way it was defined in the CEQ's 1978 regulations, with clarifying 
emphasis that the subject of analysis is the Federal action, not action 
taken by non-Federal entities. See 40 CFR 1508.25(a)(1) (rescinded). 
Even as originally defined in CEQ's 1978 regulations, the term 
``cumulative impact'' referred to the ``incremental impact'' of the 
agency proposed action in relation to the context within which that 
action was taken. See 40 CFR 1508.7 (rescinded). That is, the focus, 
even of the ``cumulative impact analysis'' should always have been on 
change wrought by the effects of the proposed action, and Seven County 
Infrastructure Coalition merely refines that focus.
    As to one term--climate change--to which the comment refers, that 
term has never appeared in DOI's NEPA procedures previously.
    DOI will conduct its NEPA reviews in accordance with statutory 
requirements and relevant caselaw, such as the Supreme Court's decision 
in Seven County Infrastructure Coalition.

F. Alternative Arrangements

    Comment: Various commenters urged the Department to reconsider 
decisions made in reliance on alternative arrangements for compliance 
with NEPA. Alternative arrangements are flexible procedures authorized 
by CEQ that agencies can use when there is an immediate threat to human 
health or safety, urgent action is needed to protect valuable natural 
or cultural resources, and the standard process would create delays in 
critical response efforts (collectively described in DOI's regulations 
as ``Emergency Responses''). In addition, several commenters raised 
questions regarding the use of alternative arrangements for energy-
related projects related to E.O. 14156, Declaring a National Energy 
Emergency.
    Response: These comments are outside the scope of this rulemaking. 
Importantly, these alternative arrangements do not waive NEPA 
compliance, they simply provide a different path to meets its 
requirements. Particular determinations under the DOI NEPA procedures 
related to E.O. 14156 are not within the scope of this rulemaking, 
which pertains solely to the establishment or revision of DOI 
procedures for compliance with NEPA.
    Comment: A commenter requested that DOI remove the discretionary 
authority currently granted to Responsible Officials in the DOI NEPA 
procedures, such as the alternative arrangements under 43 CFR 46.150.
    Response: It is appropriate for Responsible Officials to have a 
degree of discretion in conducting NEPA reviews, especially with 
respect to internal procedures. Further, DOI does not claim to have the 
authority to exempt actions from NEPA or to otherwise excuse 
noncompliance, regardless of whether an emergency exists. DOI's 
emergency response provisions, including its ``alternative 
arrangements'' process, do not circumvent NEPA compliance obligations 
but rather enable DOI to establish alternative means for NEPA 
compliance to ensure that it can act swiftly to address emergencies 
while also meeting its statutory obligations under NEPA.

G. Applicant-Prepared Information and Environmental Documents

    Comment: Some commenters expressed concern about the procedures and 
content associated with applicant-prepared environmental assessments 
and environmental impact statements stating they do not provide enough 
guidance, may create a risk of bias and conflict of interest, and raise 
questions about the scientific accuracy of the NEPA analyses in the 
documents.
    Response: As noted in the IFR, DOI is ensuring that its procedures 
conform to the statute, including the amendments made by the FRA 
directing agencies to provide for procedures governing applicant-
prepared environmental assessments and environmental impact statements 
42 U.S.C. 4336a(f). In the IFR, DOI established procedures for 
applicant-prepared environmental assessments and environmental impact 
statements at 43 CFR 46.107. These procedures ensure that applicant-
prepared NEPA documents are completed according to standards required 
by the DOI Responsible Official. They require the submission of a 
professional integrity statement by the applicant or applicant-directed 
contractor, as applicable. Id. at 46.107(g). They also require 
applicants or their contractors to furnish to DOI bureaus ``all 
relevant supporting information, including all studies, surveys, and 
technical reports'' used to support applicant-prepared environmental 
assessments or environmental impact statements. Id. at 46.107(f). 
Applicants or their contractors must further ``certify that the 
materials provided to the bureau are complete for the bureau's 
independent review.'' Id. As to conflicts of interest, the fact that 
NEPA provides for applicants (who, by definition, have an interest in 
the outcome of the Federal review of their application) to prepare NEPA 
documents in the first instance indicates Congress resolved any concern 
over potential conflicts of interest in favor of allowing applicant and 
applicant-contractor prepared NEPA documents. As outlined in the FRA, 
it is ultimately the responsibility of DOI to ensure applicant-prepared 
documents comply with NEPA and associated DOI policy. DOI's NEPA 
procedures therefore clarify that each DOI bureau relying on an 
applicant-prepared environmental assessment or environmental impact 
statement ``must independently evaluate and verify that the 
environmental analysis, including the methodologies used by the 
applicant or applicant-directed contractor,'' and verify that the 
environmental analysis meets applicable legal and bureau standards. Id.
    Comment: At least one commenter stated that NEPA does not preclude 
applicant preparation of documentation, even beyond environmental 
assessments and environmental impact statements. The commenter 
requested that DOI make clear in the regulation that Determination of 
NEPA Adequacy (DNA) checklists may be prepared by applicants and 
applicant-directed contractors.
    Response: NEPA directs agencies to ``prescribe procedures'' 
governing the preparation of an environmental assessment or 
environmental impact statement, consistent with the agency's statutory 
obligation to ``independently

[[Page 8755]]

evaluate the environmental document and . . . take responsibility for 
the contents.'' 42 U.S.C. 4336a(f). DOI's final rule does so at 43 CFR 
46.107. Additionally, the rule does not preclude preparation of split 
documents (i.e., drafted in part by an applicant or applicant-directed 
contractor and in part by the agency), nor does it preclude applicants 
from providing information to assist DOI in the preparation of 
environmental documentation, such as DNA checklists. When not preparing 
the environmental assessment or environmental impact statement, 
applicants may provide information that the Responsible Official 
evaluates and uses in the environmental review or making a 
determination of NEPA compliance.

H. Categorical Exclusions and Extraordinary Circumstances

    Comment: Some commenters expressed concerns regarding a perceived 
overreliance on categorical exclusions in the DOI NEPA procedures, 
stating that categorical exclusions could be used to circumvent 
engaging the public in environmental reviews.
    Response: Categorical exclusions can apply to a category of actions 
that a Federal agency has determined normally does not significantly 
affect the quality of the human environment within the meaning of 
section 4332(2)(C) of the statute. 42 U.S.C. 4336e(1). Categorical 
exclusions are a longstanding and legally recognized tool under NEPA 
that allow agencies to efficiently manage routine actions that they 
have determined do not normally result in any significant effects to 
the human environment. See 43 CFR 46.205. Categorical exclusions remain 
a vital tool for streamlining environmental review. Categorical 
exclusions established or adopted for the use of the bureaus are 
included in Appendix 2 of the DOI NEPA Handbook and are tailored to 
bureau-specific activities, such as routine maintenance, administrative 
actions, and certain land management operations. It is important to 
note that the DOI NEPA Handbook requires that before applying a 
categorical exclusion, each proposed action must undergo a review to 
determine that it applies and that no extraordinary circumstances exist 
(see 43 CFR 46.215). Finally, expanding or updating categorical 
exclusions does not limit public involvement for projects where 
significant effects are possible.
    Comment: One commenter suggested that the ``[P]roposal to allow any 
of [DOI's] individual bureaus to utilize any categorical exclusions 
adopted by any other bureau within DOI is far too sweeping [and] may be 
suitable only to the other bureau's circumstances'' and potentially 
unsuitable to covering another bureau-specific action.
    Response: The focus of a categorical exclusion is on the 
characteristics of the proposed action and that the proposed action 
does not result in significant impacts, not on the identity of the 
agency that conducts the action. There is, therefore, no reason in 
principle that a bureau cannot apply another agency's categorical 
exclusion for the same kind of proposed action. Should a bureau's 
proposed action be different from the proposed action encompassed by 
the other bureau's categorical exclusion, there would be no reason for 
the bureau to apply that other bureau's categorical exclusion, and the 
concerns the commenter raises would not arise. Likewise, where a 
bureau's categorical exclusion could apply only to that bureau's 
actions--for example, because of unique programmatic aspects--other 
bureaus could not seek to apply that CE to their actions. In the case 
of DOI bureaus being able to use one another's categorical exclusions, 
DOI bureaus also share the same extraordinary circumstances review 
protocol and are readily able to confer with their sister bureaus when 
questions arise.
    Comment: Commenters expressed concern with applying multiple 
categorical exclusions to a proposed action, including one commenter 
that suggested the use of multiple categorical exclusions for a 
proposed action would violate NEPA.
    Response: NEPA allows an agency to rely on multiple categorical 
exclusions to approve a single proposed action, provided that the 
agency verifies that no extraordinary circumstances are present. For 
example, if a DOI bureau determines that more than one categorical 
exclusion supports a proposed action in its entirety, and if the bureau 
further determines that no extraordinary circumstances are present, 
then the bureau can authorize the action using alternative or multiple 
categorical exclusions, documenting reliance on those categorical 
exclusions, as appropriate, in one categorical exclusion determination.
    A DOI bureau might also determine that categorical exclusions apply 
to every constituent element of a proposed action, even though no one 
categorical exclusion may apply to all of those constituent elements. 
Under DOI's NEPA procedures, the DOI bureau may, in such cases, use 
multiple categorical exclusions, ensuring that at least one categorical 
exclusion supports each element of the proposed action, and provided 
that the DOI bureau completes extraordinary circumstance review for the 
proposed action as a whole. This approach promotes permitting 
efficiency by allowing DOI bureaus to exercise discretion to rely on 
multiple appropriate categorical exclusions to authorize broader 
actions. NEPA does not require DOI bureaus, when using categorical 
exclusions, to contrive smaller proposed actions by artificially 
breaking apart larger ones. DOI's more efficient approach is consistent 
with NEPA because, crucially, the agency must determine that each 
element of a larger proposal is not the type of action that normally 
results in significant effects to the human environment. And DOI's NEPA 
procedures safeguard against the possibility that applying multiple 
categorical exclusions to a proposed action in this manner would result 
in significant effects. In particular, DOI will evaluate for 
extraordinary circumstances and will not apply a CE to a particular 
action if it might result in significant effects. See 43 CFR 
46.205(c)(1) (requiring DOI bureaus to prepare ``further analysis and 
environmental documents'' for an action if any extraordinary 
circumstances are present).
    Comment: One commenter noted that the Department's categorical 
exclusion list should be expanded to include categorical exclusions 
from external agencies.
    Response: The DOI has not included the categorical exclusions of 
external agencies unless a DOI bureau has complied with the 
requirements of NEPA Section 109 regarding adoption of another agency 
categorical exclusion, i.e., non-Department or bureau categorical 
exclusions. These categorical exclusions are in Appendix 2 of the DOI 
NEPA Handbook.
    Comment: One commenter argued that there is ``improper expansion of 
the availability of categorical exclusions and adoption of unlawful 
procedures for their establishment and application in violation of the 
statute'' under section 4336c of NEPA and stated that it is unclear 
what is required for relying on another agency's categorical exclusion 
determination, including whether a DOI extraordinary circumstances 
review is necessary.
    Response: If one agency determines that a categorical exclusion 
applies to a proposed action and another agency is taking substantially 
the same action, then there is no reason why the second agency cannot 
rely on the first agency's determination that a categorical exclusion 
applies to the action. Agency A's determination that the action fits 
within a particular category of actions for which Agency A does not 
anticipate

[[Page 8756]]

significant effects is available for Agency B to rely on, where Agency 
B is taking substantially the same action. It is important to note that 
reliance on another agency's categorical exclusion determination has 
been available to bureaus since the 2020 CEQ NEPA regulation (see 40 
CFR 1506.3(d) (2020), which used the term ``adoption'' to describe this 
concept) and, based on experience to date, DOI proposes no change to 
this procedure other than to incorporate the procedure in its own 
regulation.
    Comment: One commenter questioned why categorical exclusions 
established by section 390 of the Energy Policy Act (EPAct) were not 
subject to extraordinary circumstances review since ``the statute does 
not absolutely require those activities to be excluded from NEPA 
review.''
    Response: DOI has not changed its position regarding the Bureau of 
Land Management's use of the EPAct section 390 categorical exclusions. 
This protocol for use of these categorical exclusions has been in place 
almost since the enactment of the EPAct of 2005, was noticed and 
explained in the Federal Register at 85 FR 25472 (May 1, 2020) and is 
merely repeated in the DOI NEPA procedures.
    Comment: Several commenters asserted that the removal of three 
extraordinary circumstances at 43 CFR 46.215(c), (i), and (j) (2008), 
and revision of other extraordinary circumstances was without reasoned 
explanation. At least one commenter provided examples of purported 
``unresolved conflicts concerning alternative uses of available 
resources'' citing 2024 CEQ NEPA regulations and suggested that the 
``highly controversial'' criterion that was eliminated is not 
sufficiently addressed by other extraordinary circumstances. Several 
other commenters supported the DOI's removal of these extraordinary 
circumstances.
    Response: As part of the Department's ongoing efforts to modernize 
and streamline its NEPA procedures, these revisions reflect a 
deliberate and necessary recalibration of our regulatory framework in 
light of recent legal, executive, and statutory developments.
    Paragraph (i) was removed because 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 
Official when making the decision on the proposed action. While some 
commenters speculated specifically that this extraordinary circumstance 
was grounded in the statutory direction that agencies consider 
``comments and views of the appropriate Federal, State, and local 
agencies, which are authorized to develop and enforce environmental 
standards,'' see 43 U.S.C. 4332(C)(v), and that the removal of the 
extraordinary circumstance might prevent a DOI bureau or the public 
from considering how an action might have legal infirmities, these 
concerns are misplaced. For actions that ``may violate a Federal, 
State, local, or Tribal law'' imposed for the protection of the 
environment, the Department will continue to comply with all applicable 
laws and continue to consider State, local, and Tribal laws in its 
decision-making process. These concerns also misunderstand the reason 
that agencies review categorically excluded actions for extraordinary 
circumstances, which is to evaluate whether a proposed action might 
have significant environmental effects. Federal, State, local, and 
Tribal laws--even those directed towards the protection of the 
environment--often balance a number of competing political or policy 
objectives. They simply do not provide a sound basis for evaluating 
whether a proposed Federal action may have significant environmental 
effects within the meaning of NEPA. For these reasons, DOI has changed 
its position and eliminated this extraordinary circumstance.
    Paragraph (j) regarding environmental justice impacts was 
promulgated in response to E.O. 12898, Federal Actions To Address 
Environmental Justice in Minority Populations and Low-Income 
Populations (Feb. 11, 1994), but that E.O. was rescinded by E.O. 14173. 
Therefore, it is appropriate to remove the associated provision.
    Furthermore, and to provide further clarity, paragraph (c) has been 
removed as it causes confusion and has been frequently misunderstood to 
mean that any controversy surrounding the substance of the action 
itself constitutes an extraordinary circumstance. The concept is 
sufficiently addressed in existing paragraph (d), which the final rule 
renumbered as paragraph (c) and which applies to proposed actions where 
there are highly uncertain and potentially significant environmental 
effects or that involve unique or unknown environmental risks. If a 
proposed action's environmental effects are highly uncertain and have 
potentially significant effects or involve unique or unknown 
environmental risks, that extraordinary circumstance (c), which remains 
in DOI's NEPA regulations, would apply.
    Finally, the term ``cumulative'' was appropriately removed from 43 
CFR 46.215(f) (2008), now paragraph (e) in this section, as 
unnecessary. In addition, 43 CFR 46.215(k) and (l) (2008), now 
paragraphs (h) and (i) in this section, were appropriately revised to 
focus their application on whether there is a potential for significant 
effects.
    Comment: One commenter noted that the removal of paragraph (i) 
addressing any violation of Federal, State, local or Tribal law from 
the list of extraordinary circumstances at 43 CFR 46.215 (2008) is not 
consistent with E.O. 13132, Federalism (Aug. 4, 1999), where it is 
stated that Federal rulemakings should not affect the ``distribution of 
power and responsibilities among the various levels of government.''
    Response: As explained above, violation of a Federal, State, local 
or Tribal law imposed for the protection of the environment is not an 
issue of environmental effect but a question of compliance with law; 
therefore, it need not be considered when reviewing environmental 
effects.

I. Laws, Regulations, and Authorities Other Than NEPA

    Comment: Various commenters raised concerns regarding other laws 
that could affect environmental reviews or decision-making, including 
the Federal Land Policy and Management Act, Organic Act, Surface Mining 
Control and Reclamation Act, and Endangered Species Act.
    Response: As noted, there are some laws or regulations that might 
also apply when bureaus make decisions regarding Federal actions and 
these still apply, including any public participation requirements. 
Compliance with these other laws does not depend on how an agency 
complies with NEPA.
    Comment: Several commenters stated that for the rulemaking DOI was 
required to engage in consultation with the National Marine Fisheries 
Service and the FWS, as appropriate, under Section 7 of the ESA, which 
requires each Federal agency to ``insure [sic] 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'' any designated critical habitat.
    Response: DOI has determined that to the extent to which Section 7 
of the ESA may apply to this rulemaking action neither the IFR nor this 
rulemaking affects listed species or critical habitat, as it is 
entirely procedural and relates to how the DOI and its bureaus proceed 
to evaluate the environmental effects of

[[Page 8757]]

their actions. That is, neither the DOI NEPA implementing regulations 
themselves, nor the action to amend them, result in any environmental 
effects; therefore, this procedural rulemaking would not result in 
adverse impacts on endangered or threatened species or critical 
habitat. Rather, NEPA and its implementing regulations provide 
procedures to ensure that DOI accounts for the environmental effects of 
its actions. Any alleged harm to species raised by the commenter is 
speculative. To the extent any harm occurs, it would result from 
separate future agency actions, not DOI's establishment or revision of 
NEPA procedures. Moreover, these future actions remain subject to 
Section 7 of the ESA, as applicable.

J. Comments on the Regulatory Analyses and Notices

    Comment: One commenter noted that the rulemaking Regulatory Impact 
Analysis acknowledges that the rule will have a significant impact, and 
argues that this significance means that this rulemaking action is 
subject to an environmental assessment or environmental impact 
statement under NEPA. The commenter states that the Regulatory Impact 
Analysis ``only discusses potential cost savings and fails to analyze 
the increased costs associated with an uncertain NEPA process that 
presents litigation risks'' and notes that ``the lack of permitting 
certainty has significant impacts on public health and safety [and] 
creates highly uncertain and unique risks'' especially for 
infrastructure projects. In addition, ``[s]ince the Handbook could be 
changed arbitrarily, nothing in it can be relied upon to mitigate these 
effects.''
    Response: The determination by the Office of Management and Budget 
(OMB) under E.O. 12866, Regulatory Planning and Review, and E.O. 13563, 
Improving Regulation and Regulatory Review, that a rulemaking is 
significant is separate from a determination of applicability and 
necessary level of review under NEPA. As stated in the IFR and this 
final rule, the rulemaking was deemed ``significant'' by OMB as that 
word is understood in the context of E.O. 12866. The DOI rule is 
considered economically significant since DOI expects that revisions 
and updates to the DOI NEPA implementing regulations will have a broad 
range of cost savings for the Federal Government, interested 
stakeholders, and DOI applicants. The commenter's examples of 
permitting uncertainty are not directly related to the appropriate 
level of NEPA review for the IFR or this final rule. While the DOI NEPA 
procedures provide for the consideration of environmental effects in 
decision-making processes, including economic, public health, and 
safety, DOI does not believe that this rule will 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. Under DOI NEPA procedures, DOI determined that a 
categorical exclusion was an appropriate level of NEPA review for this 
rulemaking.
    Comment: Several commenters expressed concern that the rule may 
disproportionately affect small municipalities, Tribal governments, and 
local water authorities.
    Response: As the Department is not required to publish a notice of 
proposed rulemaking for this IFR, the Regulatory Flexibility Act (RFA) 
does not apply. The RFA generally requires agencies to assess the 
impact of final rules on small entities. Even if the RFA were to apply, 
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.

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 the OIRA in the OMB 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 final rule is a significant 
regulatory action under section 3(f) of E.O. 12866, and has reviewed 
this final rule.

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act, as amended, (RFA), 5 U.S.C. 601 et 
seq., and E.O. 13272, Proper Consideration of Small Entities in Agency 
Rulemaking (August 13, 2002), 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 was not required to publish a notice of proposed rulemaking 
for this 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 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 additional NEPA 
review of the effects of this final rule. DOI finds this rulemaking is 
excluded pursuant to its categorical exclusion at 43 CFR 46.210(i). The 
categorical exclusion 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 final rule does not 
implicate any of the extraordinary circumstances listed in 43 CFR 
46.215. The promulgation of NEPA implementing procedures is not 
generally itself subject to NEPA. Heartwood v. U.S. Forest Serv., 230 
F.3d 947, 954-55 (7th Cir. 2000).

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 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

[[Page 8758]]

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 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 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 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 U.S.C. 1532. This 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 final rule also 
does not impose any enforceable duty, contain any unfunded mandate, or 
otherwise have any effect on small governments.

I. Paperwork Reduction Act

    This 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 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, consistent with 42 U.S.C. 4332(2)(E) and 
Secretary's Order 3441, Implementing the Requirements of Executive 
Order 14303, Restoring Gold Standard Science 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 relied on, as needed, to verify the 
analyses.

[[Page 8759]]

    (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 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.
    (h) 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 actions to 
address imminent threats to life, property, or important natural, 
cultural, or historic resources before preparing an environmental 
document or documenting the 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 address imminent threats 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 consider taking steps to mitigate 
reasonably foreseeable adverse environmental impacts to the extent 
practicable and consistent with agency authority.
    (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 that makes it necessary to take action before 
preparing 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).

[[Page 8760]]

    (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), (d), or (e) 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 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) Bureaus may apply multiple categorical exclusions in 
combination to cover a proposed action composed of multiple action 
elements. In some circumstances, a bureau might consider a proposed 
action that is a composite of multiple smaller actions or action 
elements. In such instances, a combination of categorical exclusions--
each covering an action that is an element of the larger proposed 
action--can cover all the actions or action elements composing the 
larger composite action and support the bureau's determination that it 
is not reasonably foreseeable that the effects of the composite 
proposed action, with all its elements, would be significant. When a 
bureau completes its review of a proposed action composed of several 
action elements in reliance on multiple categorical exclusions, the 
bureau must concisely document this reliance, including by verifying 
that each smaller action or action element is supported by a 
categorical exclusion and completing all applicable review for the 
presence of extraordinary circumstances that, if present, would 
preclude application of the categorical exclusions to the larger or 
composite 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 paragraph (h)(3) of this section; 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) 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. Reliance on paragraphs (a) through (j) of this section to 
support approval of a proposed action does not need to be documented; 
reliance on paragraph (k) or (l) of this section to support approval of 
a proposed action does need to 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

renovations, and replacement activities having limited context and 
intensity (e.g., limited size and magnitude or short-term effects).
    (g) Management, formulation, allocation, transfer, and 
reprogramming of the Department's budget at all levels. (This does not 
exclude the preparation of environmental documents for proposals 
included in the budget when otherwise required.)

Implementation Plan;''
    (3) Shall be conducted consistent with bureau and Departmental 
procedures and applicable land and resource management plans;
    (4) Shall not be conducted in wilderness areas or impair the 
suitability of wilderness study areas for preservation as wilderness; 
and
    (5) Shall not include the use of herbicides or pesticides or the 
construction of new permanent roads or other new permanent

damage to minor facilities such as campgrounds) to repair or improve 
lands unlikely to recover to a management approved condition from 
wildland fire damage, or to repair or replace minor facilities damaged 
by fire. Such activities must comply with the following:
    (1) Shall be conducted consistent with bureau and Departmental 
procedures and applicable land and resource management plans;
    (2) Shall not include the use of herbicides or pesticides or the

Sec.  46.215  Categorical exclusions: Extraordinary circumstances.

    Extraordinary circumstances (see Sec.  46.205(c)) exist for 
individual actions within categorical exclusions that may meet any of 
the criteria listed in paragraphs (a) through (i) of this section. 
Applicability of extraordinary circumstances to categorical exclusions 
is determined by the Responsible Official. If an extraordinary 
circumstance is not present, the Responsible Official may determine 
that the categorical exclusion applies to the proposed action and 
conclude review.
    (a) Have significant impacts on public health or safety.
    (b) Have significant impacts on such natural resources and unique 
geographic characteristics as historic or cultural resources; park, 
recreation or refuge lands; wilderness areas; wild or scenic rivers; 
national natural landmarks; sole or principal drinking water aquifers; 
prime farmlands; wetlands; floodplains; national monuments; migratory 
birds; and other ecologically significant or critical areas.
    (c) Have highly uncertain and potentially significant environmental 
effects or involve unique or unknown environmental risks.
    (d) Establish a precedent for future action or represent a decision 
in principle about future actions with potentially significant 
environmental effects.
    (e) Have a direct relationship to other actions that implicate 
potentially significant environmental effects.
    (f) Have significant impacts on properties listed, or eligible for 
listing, on the National Register of Historic Places as determined by 
the bureau.
    (g) Have significant impacts on species listed, or proposed to be 
listed, on the List of Endangered or Threatened Species or have 
significant impacts on designated Critical Habitat for these species.
    (h) Significantly limit access to and ceremonial use of Indian 
sacred sites on Federal lands by Indian religious practitioners or 
significantly adversely affect the physical integrity of such sacred 
sites.
    (i) Contribute to potentially significant effects resulting from 
the introduction, continued existence, or spread of noxious weeds or 
non-native invasive species known to occur in the area or from other 
actions that promote the introduction, growth, or expansion of the 
range of such species (Federal Noxious Weed Control Act).


Sec.  46.220  How to designate lead agencies.

    (a) In most cases, the Responsible Official should designate one 
Federal agency as the lead with the remaining Federal, State, Tribal, 
and local agencies assuming the role of cooperating agency. In this 
manner, the other Federal, State, Tribal, and local agencies can work 
to ensure that the environmental impact statement will meet their needs 
for adoption and application to any related decision.
    (b) In some cases, a non-Federal agency (including a State, Tribal, 
or local government) must comply with State, Tribal, or local 
requirements that are comparable to the NEPA requirements. In these 
cases, the Responsible Official may designate the non-Federal agency as 
a joint lead agency.
    (c) In some cases, the Responsible Official may establish a joint 
lead relationship among several Federal agencies. If there are joint 
leads for an environmental impact statement, then one Federal agency 
must be identified as the agency responsible for filing the 
environmental impact statement with the Environmental Protection 
Agency.
    (d) Bureaus may allow joint lead agencies to cooperate in 
developing environmental assessments.


Sec.  46.225  How to select cooperating agencies.

    (a) An eligible agency is:
    (1) Any Federal, State, Tribal, or local agency that is qualified 
to participate in the development of an environmental assessment or 
environmental impact statement by virtue of its jurisdiction by law, 
consistent with 42 U.S.C. 4336a(a)(3);
    (2) Any Federal, State, Tribal, or local agency that is qualified 
to participate in the development of an environmental assessment or 
environmental impact statement by virtue of its special expertise.\1\

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

    (b) The Responsible Official for a lead bureau may invite eligible 
agencies to participate as cooperating agencies

[[Page 8762]]

when the bureau is developing an environmental assessment and must 
invite eligible agencies to participate as cooperating agencies when 
the bureau is developing an environmental impact statement, subject to 
the exception described in paragraph (c) of this section.
    (c) The Responsible Official for the lead bureau must consider any 
request by an eligible agency to participate in a particular 
environmental impact statement or environmental assessment as a 
cooperating agency. Such request shall not be arbitrarily denied. If 
the Responsible Official for the lead bureau denies a request, or 
determines it is inappropriate to extend an invitation, he or she must 
state the reasons in the environmental impact statement or 
environmental assessment, as applicable. Denial of a request for 
cooperating agency status is not subject to any internal administrative 
appeals process, nor is it a final agency action subject to review 
under the Administrative Procedure Act, 5 U.S.C. 701 et seq.
    (d) Bureaus should work with cooperating agencies to develop and 
adopt appropriate documentation that includes their respective roles, 
assignment of issues, schedules, and staff commitments so that the NEPA 
process remains on track and within the time schedule. Such 
documentation must be used in the case of non-Federal agencies and must 
include a commitment to maintain the confidentiality of documents and 
deliberations during the period prior to the public release by the 
bureau of any environmental document, including drafts, to the extent 
permitted by the Freedom of Information Act and other applicable law. 
However, no memorandum can require a cooperating agency to waive the 
right to judicial review.
    (e) Bureaus within the Department will be cooperating agencies with 
other bureaus when requested.
