Generic Environmental Impact Statement for Licensing of New 
Nuclear Reactors

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule, draft guidance, and draft generic environmental 
impact statement; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is proposing to 
amend the regulations that govern the NRC's environmental reviews of 
new nuclear reactor applications under the National Environmental 
Policy Act. The rulemaking would codify the generic findings of the 
NRC's draft Generic Environmental Impact Statement for Licensing of New 
Nuclear Reactors. The draft Generic Environmental Impact Statement for 
Licensing of New Nuclear Reactors uses a technology-neutral framework 
and a set of plant and site parameters to determine which potential 
environmental impacts would be common to the construction, operation, 
and decommissioning of many new nuclear reactors, and thus appropriate 
for a generic analysis, and which potential environmental impacts would 
be unique, and thus require a project-specific analysis. The NRC 
expects that both the proposed rule and the Generic Environmental 
Impact Statement for Licensing of New Nuclear Reactors would streamline 
the environmental reviews for future nuclear reactor applicants. The 
NRC is also issuing for public comment draft regulatory guide (DG), 
``Preparation of Environmental Reports for Nuclear Power Stations,'' 
and ``Environmental Considerations Associated with New Nuclear Reactor 
Applications that Reference the Generic Environmental Impact 
Statement.''

DATES: Submit comments by December 18, 2024. Comments received after 
this date will be considered if it is practical to do so, but the 
Commission is able to ensure consideration only for comments received 
before this date. The NRC plans to hold three public meetings to 
promote a full understanding of the proposed rule and facilitate public 
comments. Public meetings will be held on November 7, 2024, November 
13, 2024, and November 14, 2024. See Section XV, ``Public Meetings,'' 
of this document for more information on the meetings.

ADDRESSES: You may submit comments by any of the following methods 
(unless this document describes a different method for submitting 
comments on a specific subject); however, the NRC encourages electronic

SUPPLEMENTARY INFORMATION:

Executive Summary

A. Purpose of the Regulatory Action

    The U.S. Nuclear Regulatory Commission (NRC) is proposing to revise 
its regulations to codify the findings of the draft generic 
environmental impact statement, NUREG-2249, ``Generic Environmental 
Impact Statement for Licensing of New Nuclear Reactors'' (NR GEIS). The 
draft NR GEIS analyzes the potential environmental impacts of the 
construction, operation, and decommissioning of a new nuclear reactor. 
The NR GEIS is intended to improve the efficiency of the NRC staff's 
environmental review of a new nuclear reactor application by 
identifying those potential environmental issues that are expected to 
be common, or generic, to the construction, operation, and 
decommissioning of many new nuclear reactors. If the Commission 
approves issuance of the NR GEIS, the NRC staff would be able to rely 
on the NR GEIS' generic findings when conducting a subsequent, project-
specific environmental review for a new nuclear reactor if specific 
conditions are met. The proposed rule would codify these generic 
findings into the NRC's regulations in part 51 of title 10 of the Code 
of Federal Regulations (10 CFR), ``Environmental Protection Regulations 
for Domestic Licensing and Related Regulatory Functions,'' thus making 
the NRC's licensing process for new nuclear reactors more efficient. 
Specifically, these findings would be codified into subpart A of 10 CFR 
part 51, which sets forth the NRC's regulations to implement its 
obligations under the National Environmental Policy Act (NEPA).\1\
---------------------------------------------------------------------------

    \1\ 42 U.S.C. 4321 et seq. (1969).

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

[[Page 80798]]

B. Major Provisions

    Major provisions of this proposed rule and guidance would include:
    1. Addition of a new appendix C, ``Environmental Effect of Issuing 
a Permit or License for a New Nuclear Reactor,'' to subpart A of 10 CFR 
part 51 to codify the findings in the NR GEIS and state that, on a 10-
year cycle, the Commission intends to review the material in this 
appendix and update if necessary.
    2. Changes to the regulations for the preparation of environmental 
reports for new reactors (Sec.  51.50, ``Environmental report--
construction permit, early site permit, or combined license stage'') to 
provide the applicant with the option to use the NR GEIS.
    3. Changes to the regulations for the preparation of draft 
environmental impact statements (EISs) for new reactors (Sec.  51.75, 
``Draft environmental impact statement--construction permit, early site 
permit, or combined license'') to require the NRC staff to use the NR 
GEIS in preparing its draft EIS if an applicant for a new nuclear 
reactor referenced the NR GEIS in its application.
    4. Addition of new section (Sec.  51.96, ``Final supplemental 
environmental impact statement relying on Appendix C to Subpart A'') to 
provide the NRC staff with directions on the preparation of final EISs 
that reference the NR GEIS.
    5. Draft revisions to Regulatory Guide (RG) 4.2, ``Preparation of 
Environmental Reports for Nuclear Power Stations,'' \2\ to provide 
guidance to applicants regarding the use of the NR GEIS. In addition, 
the NRC staff has prepared a draft interim staff guidance document, 
COL-ISG-030, ``Environmental Considerations Associated with New Nuclear 
Reactor Applications that Reference the Generic Environmental Impact 
Statement (NUREG-2249)'' to provide guidance to the NRC staff regarding 
the use of the NR GEIS.
---------------------------------------------------------------------------

    \2\ Unless stated otherwise, references to RG 4.2 refer to DG-
4032, the draft revision to RG 4.2, which is being published at the 
same time as this notice.
---------------------------------------------------------------------------

C. Costs and Benefits

    The NRC prepared a draft regulatory analysis to determine the 
expected quantitative costs and benefits of this proposed rule and 
associated guidance. Assuming 20 applications over the next decade, the 
regulatory analysis concluded that, compared to the no-action 
alternative, the proposed rule alternative and associated guidance 
would result in undiscounted total net savings for the NRC and 
applicants up to $40.1 million or $2.0 million per application if the 
NR GEIS is fully utilized.
    The draft regulatory analysis also considered qualitative factors 
to be considered in the NRC's rulemaking decision. Qualitative aspects 
include greater regulatory stability, predictability, and clarity to 
the licensing process. The proposed rule would reduce the cost to 
industry of preparing environmental reports for new nuclear reactor 
applications by focusing resources on project-specific analyses. The 
NRC also would recognize similar reductions in cost and be better able 
to focus its resources on the project-specific issues during new 
nuclear reactor licensing environmental reviews.
    The NR GEIS could potentially be utilized for micro-reactors, but 
the NRC staff does not have sufficient information at this time to 
determine whether the proposed rule could potentially affect any small 
entities as defined in Sec.  2.810, ``NRC size standards.'' Therefore, 
the NRC staff has included an initial regulatory flexibility analysis 
in Section VI, Regulatory Flexibility Certification, of this document 
and is requesting public comment on the potential impact of the 
proposed rule on small entities.
    For more information, please see the draft regulatory analysis 
(available as indicated in Section XVI, Availability of Documents, of 
this document).

II. Background

    The Generic Environmental Impact Statement for Licensing of New 
Nuclear Reactors (NR GEIS) is intended to streamline the NRC's 
environmental review for new nuclear reactor applications received as 
part of the reactor licensing process.\3\ This Background section 
provides an overview of the two existing reactor licensing processes, 
10 CFR part 50, ``Domestic Licensing of Production and Utilization 
Facilities,'' and 10 CFR part 52, ``Licenses, Certifications, and 
Approvals for Nuclear Power Plants,'' under which an applicant may 
apply for a license for a new nuclear reactor. This section also 
describes the environmental review process and the Commission's policy 
and past practice with respect to the use of generic rulemakings to 
adopt improvements to the licensing process.
---------------------------------------------------------------------------

    \3\ In staff requirements memorandum, SRM-SECY-20-0020, 
``Results of Exploratory Process for Developing a Generic 
Environmental Impact Statement for the Construction and Operation of 
Advanced Nuclear Reactors,'' dated September 21, 2020, the 
Commission approved the development of a GEIS for the construction 
and operation of advanced nuclear reactors and directed staff to 
codify the generic findings in the Code of Federal Regulations. In 
SRM-SECY-21-0098, ``Proposed Rule: Advanced Nuclear Reactor Generic 
Environmental Impact Statement,'' dated April 17, 2024, the 
Commission directed the staff to proceed with publication of the NR 
GEIS after modifying it to be applicable to any new nuclear reactor 
application.
---------------------------------------------------------------------------

A. New Reactor Licensing Processes--10 CFR Part 50 and 10 CFR Part 52

    The NRC licenses and regulates the construction and operation of 
nuclear reactor facilities in the United States. The NRC's evaluation 
and ultimate decision on a reactor application will involve a safety 
review, governed by the NRC's regulations in either 10 CFR part 50 or 
10 CFR part 52, and an environmental review, governed by the NRC's 
regulations in 10 CFR part 51, ``Environmental Protection Regulations 
for Domestic Licensing and Related Regulatory Functions.'' All nuclear 
reactors that were operating prior to 2021 were licensed under a two-
step licensing process governed by 10 CFR part 50. The first step is an 
application for and issuance of a construction permit. The second step, 
upon substantial completion of facility construction, is issuance of an 
operating license.
    In an effort to improve regulatory efficiency and add greater 
predictability to the reactor licensing process, the NRC issued 10 CFR 
part 52 on April 18, 1989 (54 FR 15372). The rule added licensing 
processes for issuance of early site permits, standard design 
certifications, and combined licenses. Early site permits allow an 
applicant to obtain approval for a reactor site for future use, while 
certified standard plant designs can be used as pre-approved designs. 
Early site permits and certified designs can then be referenced in an 
application for a combined license. Combined licenses combine a 
construction permit and an operating license in a single authorization.
    A nuclear reactor applicant could apply for a license under 10 CFR 
part 50 or 10 CFR part 52. The proposed rule to adopt the generic 
environmental conclusions of the NR GEIS in 10 CFR part 51 would be 
available for use in conjunction with either of these two licensing 
processes. Additionally, the NRC staff is preparing a rulemaking that 
would provide a new framework for licensing reactors in a proposed 10 
CFR part 53.\4\ The NRC staff anticipates that the NR GEIS would be 
available for use with this new 10 CFR part 53 licensing process for 
new nuclear reactors.

Advanced Reactors (Docket ID NRC-2019-0062; RIN 3150-AK31).
---------------------------------------------------------------------------

B. Environmental Review--Current 10 CFR Part 51 Regulations

    As a Federal agency, the NRC must comply with the National 
Environmental Policy Act (NEPA) by assessing the potential 
environmental effects of a proposed agency action prior to making a 
decision to approve or disapprove of that proposed action. The 
regulations implementing the NRC's NEPA obligations are found in 10 CFR 
part 51.
    Under NEPA, the environmental review of a proposed action can 
involve one of three different levels of analysis depending on the 
significance of a proposed action's potential effects on the 
environment: (1) a categorical exclusion,\5\ (2) an environmental 
assessment,\6\ or (3) an environmental impact statement (EIS). An EIS, 
the most complex, resource-intensive, and thorough of the three levels 
of NEPA analysis, is a document that describes the potential 
environmental impacts of the proposed action as well as a reasonable 
range of alternatives to the proposed agency action. Under NEPA, 
Federal agencies shall prepare an EIS for any proposed agency action 
that may result in a significant impact to an environmental resource. 
In addition, the Commission has identified, by its Sec.  51.20, 
``Criteria for and identification of licensing and regulatory actions 
requiring environmental impact statements,'' regulation, certain 
categories of NRC proposed actions that require the preparation of an 
EIS. In this regard, Sec.  51.20(b)(1) identifies the issuance of a 
construction permit (under the 10 CFR part 50 licensing process) or an 
early site permit (under the 10 CFR part 52 licensing process) for a 
nuclear power reactor or testing facility, as proposed actions 
requiring the preparation of an EIS.\7\ Similarly, Sec.  51.20(b)(2) 
identifies the issuance or renewal of an operating license (under 10 
CFR part 50) or a combined license (under 10 CFR part 52) for a nuclear 
power reactor or testing facility, as proposed actions requiring the 
preparation of an EIS.
---------------------------------------------------------------------------

    \5\ The NRC defines a ``categorical exclusion'' as a category of 
actions which do not individually or cumulatively have a significant 
effect on the human environment and which the Commission has found 
to have no such effect in accordance with procedures set out in 
Sec.  51.22, ``Criterion for categorical exclusion; identification 
of licensing and regulatory actions eligible for categorical 
exclusion or otherwise not requiring environmental review,'' and for 
which, therefore, neither an environmental assessment nor an 
environmental impact statement is required. 10 CFR 51.14(a). The 
NRC's list of categorical exclusions is set forth in Sec.  51.22.
    \6\ The NRC defines an ``environmental assessment'' as a concise 
public document . . . that serves to: (1) Briefly provide sufficient 
evidence and analysis for determining whether to prepare an 
environmental impact statement or a finding of no significant 
impact. (2) Aid the Commission's compliance with NEPA when no 
environmental impact statement is necessary. (3) Facilitate 
preparation of an environmental impact statement when one is 
necessary. 10 CFR 51.14(a).
    \7\ The terms ``nuclear reactor'' and ``testing facility'' are 
defined in Sec.  50.2, ``Definitions.''
---------------------------------------------------------------------------

    The NRC's regulation at Sec.  51.45, ``Environmental report,'' 
requires a reactor applicant to submit an environmental report that 
discusses: (1) the impact of the proposed action on the environment, 
(2) any adverse environmental impacts that cannot be avoided, (3) 
alternatives to the proposed action, (4) the relationship between local 
short-term uses of the environment and maintenance and enhancement of

[[Page 80800]]

long-term productivity, and (5) any irreversible or irretrievable 
commitments of resources. In addition, the applicant is required to 
include in its environmental report, an analysis that considers and 
balances the environmental effects of the proposed action and the 
alternatives available for reducing or avoiding adverse environmental 
effects, as well as the benefits of the action. The NRC will 
independently evaluate the applicant's environmental report as part of 
the NRC's preparation of the draft EIS.
    Before issuing a construction permit or an operating license for a 
nuclear plant under 10 CFR part 50 or an early site permit or combined 
license (that does not reference an early site permit for the proposed 
nuclear reactor) under 10 CFR part 52, the NRC is required to prepare a 
draft EIS that assesses the potential environmental impacts that may 
result from the construction, operation, and decommissioning of the 
proposed nuclear reactor plant. In preparing the draft EIS, the NRC 
staff will analyze the potential environmental impacts in regard to 
different aspects or resources of the human environment (e.g., air 
quality). For each environmental aspect or resource area, the NRC staff 
will identify and analyze issues that correspond to specific, potential 
environmental impacts (e.g., for the air quality resource area, the 
criteria pollutant emissions likely to result during construction). In 
the draft EIS, the NRC staff also evaluates alternatives to the 
proposed agency action.
    After analyzing the potential environmental impacts for each 
issue,\8\ the NRC assigns one of the following three significance 
levels to describe its evaluation of those impacts on that issue:
---------------------------------------------------------------------------

    \8\ Each issue corresponds to a specific type of environmental 
impact potentially resulting from building, operating, or 
decommissioning of a new nuclear reactor.
---------------------------------------------------------------------------

    SMALL--The environmental effects are not detectable or are so minor 
that they will neither destabilize nor noticeably alter any important 
attribute of the resource. For the purposes of assessing radiological 
impacts, the Commission has concluded that those impacts that do not 
exceed permissible levels in the Commission's regulations are 
considered small as the term is used in this definition.
    MODERATE--The environmental effects are sufficient to alter 
noticeably, but not to destabilize, important attributes of the 
resource.
    LARGE--The environmental effects are clearly noticeable and are 
sufficient to destabilize important attributes of the resource.
    For issues where probability is a key consideration (i.e., accident 
consequences), probability is a factor in determining significance.
    The NRC will document its environmental review and analysis through 
the preparation of a draft EIS that will be published for public 
comment in the Federal Register, with a minimum 45-day comment period, 
in accordance with Sec.  51.73, ``Request for comments on draft 
environmental impact statement.'' Further, as provided in Sec.  51.74, 
``Distribution of draft environmental impact statement and supplement 
to draft environmental impact statement; news releases,'' the NRC will 
distribute the draft EIS to the Environmental Protection Agency, 
Federal agencies that have a special expertise or jurisdiction with 
respect to any potential environmental impact that may be relevant to 
the proposed action, the applicant, and appropriate State, Tribal, and 
local agencies and clearinghouses.
    Following the public comment period, the NRC will analyze any 
comments received, revise its environmental analyses as appropriate, 
and then prepare the final EIS in accordance with the requirements of 
Sec.  51.91, ``Final environmental impact statement--contents.'' \9\ 
Pursuant to Sec.  51.93, ``Distribution of final environmental impact 
statement and supplement to final environmental impact statement; news 
releases,'' the NRC will distribute the final EIS to many of the same 
entities as the draft EIS and to each commenter. The NRC also will 
publish a notice of availability for the final EIS in the Federal 
Register. As set forth in Sec.  51.102, ``Requirement to provide a 
record of decision; preparation,'' and following the preparation and 
distribution of the final EIS, the Commission will prepare and issue 
the record of decision, which is a concise, publicly-available 
statement that documents the NRC's decision, as informed by the final 
EIS. The requirements for a record of decision are described in Sec.  
51.103, ``Record of decision--general,'' and include stating the 
Commission's decision (e.g., the approval or disapproval of the nuclear 
reactor application), identifying the alternatives (including the 
proposed agency action) considered by the Commission, and a statement 
as to whether the Commission has taken all practicable measures within 
its jurisdiction to avoid or minimize environmental harm from the 
alternative selected, and if not, to explain why those measures were 
not adopted (e.g., lack of jurisdiction or authority). In cases of an 
adjudicatory proceeding before the NRC's Atomic Safety and Licensing 
Board (ASLB), the initial decision of the presiding officer, or if 
appealed, the final decision of the Commission, will constitute the 
record of decision. To meet the Sec.  51.102 requirement that the 
record of decision be a concise document, the NRC staff will also 
prepare a ``Summary Record of Decision,'' signed by the NRC's Director, 
Office of Nuclear Reactor Regulation, that summarizes the presiding 
officer's initial, or the Commission's final, decision.\10\
---------------------------------------------------------------------------

    \9\ For a 10 CFR part 52 combined license that references an 
early site permit, the NRC will prepare a supplement to the final 
EIS for the early site permit in accordance with Sec.  51.92(e) and 
will provide an opportunity for public comment on the supplement 
pursuant to Sec.  51.92(f)(1). Similarly, for a 10 CFR part 50 
operating license, the NRC will prepare a supplement to the final 
EIS for the construction permit in accordance with Sec.  51.95(b) 
and will provide an opportunity for public comment on the supplement 
pursuant to Sec.  51.95(a).
    \10\ For the issuance of a 10 CFR part 50 operating license 
supported by a supplement prepared pursuant to Sec.  51.95(b) that 
is uncontested (i.e., no hearing before the NRC's ASLB), the 
Director, Office of Nuclear Reactor Regulation, will prepare the 
record of decision in accordance with Sec.  51.103.
---------------------------------------------------------------------------

C. Use of Rulemaking and Generic Environmental Impact Statements

    The use of rulemaking to adopt improvements to the licensing 
process for classes of applicants, such as reactor applicants, has 
several advantages, including the following, which were identified in a 
1978 NRC interim policy statement: \11\ (1) enhance stability and 
predictability of the licensing process by providing regulatory 
criteria and requirements in discrete generic areas on matters which 
are significant in the review and approval of license applications; (2) 
enhance public understanding and confidence in the integrity of the 
licensing process by inviting public participation in important generic 
issues which are of concern to the agency and the public; (3) enhance 
administrative efficiency in licensing by removing, in whole or in 
part, generic issues from NRC staff review and adjudicatory resolution 
in individual licensing proceedings and/or by establishing the 
importance (or lack of importance) of various safety and environmental 
issues to the decision process; (4) assist the Commission in resolving 
complex methodological and policy issues involved in recurring issues 
in the review and approval of individual licensing applications; and

[[Page 80801]]

(5) yield an overall savings in the utilization of resources in the 
licensing process by the utility industry, those of the public whose 
interest may be affected by the rulemaking, the NRC, and other Federal, 
State, and local governments with an expected improvement in the 
quality of the decision process.
---------------------------------------------------------------------------

    \11\ Generic Rulemaking to Improve Nuclear Power Plant 
Licensing, Interim Policy Statement (43 FR 58377; December 14, 
1978).
---------------------------------------------------------------------------

    The NRC has prepared the draft NR GEIS, which provides generic 
findings with respect to many environmental issues. The NRC is 
proposing to codify these generic findings in 10 CFR part 51 to 
streamline and make more efficient the preparation of environmental 
reports by new nuclear reactor applicants and the NRC's environmental 
reviews. This proposed rule is consistent with past NRC part 51 
rulemakings that adopted generic findings with respect to certain 
environmental issues related to the reactor licensing process. For 
example, table S-3, ``Table of Uranium Fuel Cycle Environmental Data,'' 
in Sec.  51.51 identifies the generic findings related to various 
environmental impacts of the nuclear fuel cycle.\12\ As such, these 
applicants are not required to conduct their own analysis of these 
impacts in their environmental reports and the NRC staff can likewise 
rely upon these findings when preparing its draft EIS.
---------------------------------------------------------------------------

    \12\ As described in Sec.  51.51(a), the nuclear fuel cycle 
includes uranium mining and milling, the production of uranium 
hexafluoride, isotopic enrichment, fuel fabrication, reprocessing of 
irradiated fuel, transportation of radioactive materials and 
management of low-level wastes and high-level wastes related to 
these activities.
---------------------------------------------------------------------------

    Based upon past experience, the NRC has determined that the use of 
a generic environmental impact statement (GEIS) and the codification of 
the generic findings into an NRC regulation is an efficient and 
thorough method of NEPA compliance when applied to a particular class 
of facilities or licensing and regulatory actions. Specifically, the 
NRC has relied upon the ``Generic Environmental Impact Statement for 
License Renewal of Nuclear Plants'' (NUREG-1437), which was issued in 
1996 and recently updated in 2024, for operating power reactor license 
renewal actions, and the ``Generic Environmental Impact Statement for 
Continued Storage of Spent Nuclear Fuel'' (NUREG-2157), which was 
issued in 2014, for the continued storage of spent fuel beyond the 
licensed life for operation of a reactor. In this regard, the NRC added 
appendix B to 10 CFR part 51, which codifies the generic findings of 
the NUREG-1437, and amended Sec.  51.23, ``Environmental impacts of 
continued storage of spent nuclear fuel beyond the licensed life for 
operation of a reactor,'' which codifies the findings of NUREG-2157.
    The NUREG-1437, which identifies the environmental issues that may 
apply to the renewal of an operating power reactor license, serves as a 
model for the preparation of the NR GEIS. For each operating power 
reactor license renewal action, the NRC prepares a project-specific 
supplemental EIS (SEIS) that is issued as a supplement to NUREG-1437. 
To date, the NRC has issued SEISs to NUREG-1437 associated with initial 
license renewal and subsequent license renewal for 61 plants. In NUREG-
1437, the NRC staff determined that those issues that were common, or 
generic, to all nuclear reactors were identified as Category 1. 
Further, the NRC staff determined that the vast majority of the 
Category 1 issues were of a SMALL significance level.\13\ Provided that 
neither the license renewal applicant nor the NRC identifies any new 
and significant information, no further analysis is needed for that 
issue by the applicant in its environmental report or by the NRC in its 
preparation of the draft SEIS. Those issues that cannot be resolved 
generically and are identified as Category 2 issues must be analyzed by 
both the applicant in its environmental report and by the NRC in the 
draft SEIS. The applicant in its environmental report and the NRC in 
its draft SEIS must also address any new and significant information.
---------------------------------------------------------------------------

    \13\ Certain issues such as the offsite radiological impacts of 
spent nuclear fuel storage and high-level waste disposal were not 
given a significance level because of uncertainty; however, the 
Commission concluded that the impacts would not be sufficiently 
large to require the NEPA conclusion, for any plant, that the option 
of extended operation under 10 CFR part 54 should be eliminated. 
Accordingly, while the Commission has not assigned a single level of 
significance for the offsite radiological impacts of spent fuel and 
high-level waste disposal, these issues were considered to be 
Category 1 issues by the Commission.
---------------------------------------------------------------------------

    The NRC has codified the findings for the NUREG-1437 Category 1 
issues into its regulations; the findings are listed in table B-1, 
``Summary of Findings on NEPA Issues for License Renewal of Nuclear 
Power Plants,'' of appendix B to subpart A of 10 CFR part 51. The 
regulatory direction to use NUREG-1437 is set forth in Sec.  51.53(c) 
for applicant environmental reports, in Sec.  51.71(d) for the NRC 
staff's preparation of the draft SEIS, and in Sec.  51.95(c) for the 
NRC staff's preparation of the final SEIS. In accordance with Sec.  
2.335(a), the codification of the generic findings and the direction to 
use NUREG-1437 for operating power reactor license renewal actions bars 
any challenge to a generic finding or the NRC's reliance upon NUREG-
1437 in a site-specific licensing proceeding before the NRC's ASLB.\14\ 
A person seeking to challenge a codified generic finding must either 
file a petition for rulemaking pursuant to Sec.  2.802, ``Petition for 
rulemaking--requirements for filing,'' or, if a party to an ASLB 
proceeding, file a request to waive the regulation pursuant to Sec.  
2.335(b), such waiver being subject to Commission approval.
---------------------------------------------------------------------------

    \14\ 10 CFR 2.335(a) (``[N]o rule or regulation of the 
Commission, or any provision thereof, concerning the licensing of 
production and utilization facilities, source material, special 
nuclear material, or byproduct material, is subject to attack by way 
of discovery, proof, argument, or other means in any adjudicatory 
proceeding subject to this part.'').
---------------------------------------------------------------------------

    The use of a GEIS for meeting the NRC's NEPA obligations and the 
concomitant codification of generic findings into an NRC regulation has 
been upheld by Federal courts. In its 1983 decision, Baltimore Gas and 
Electric Co. v. NRDC, the Supreme Court adjudicated a challenge to 
table S-3, codified at Sec.  51.51.\15\ The Court described table S-3 
as ``a numerical compilation of the estimated resources used and 
effluents released by fuel cycle activities supporting a year's 
operation of a typical light-water reactor.'' \16\ Section 51.51 
requires that an environmental report, prepared by an applicant for a 
construction permit, an early site permit, or a combined license for a 
light-water-cooled nuclear power reactor, use the data in table S-3 
``as the basis for evaluating the contribution of the environmental 
effects'' of all aspects of the uranium fuel cycle, such as uranium 
mining and milling, ``to the environmental costs of licensing the 
nuclear power reactor.'' \17\ The Court held that ``the generic method 
chosen by the [NRC] is clearly an appropriate method of conducting the 
hard look required by NEPA.'' \18\ The Court further stated that 
``administrative efficiency and consistency of decision are both 
furthered by a generic determination of these effects without needless 
repetition of the litigation in individual proceedings, which are 
subject to review by the Commission in any event.'' \19\ Lower Federal 
courts have applied the Baltimore Gas holding to the NRC's reliance on 
NUREG-1437 for operating power license renewal

findings of NUREG-2157 into Sec.  51.23 have been upheld.\21\

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

D. Advanced Nuclear Reactors

    The NRC initially developed NUREG-2249 as a document that would be 
applicable only to ``advanced nuclear reactors'' that met the values 
and assumptions of the plant parameter envelopes and the site parameter 
envelopes used to develop the GEIS. See SECY-21-0098, ``Proposed Rule: 
Advanced Nuclear Reactor Generic Environmental Impact Statement (RIN 
3150-AK55; NRC-2020-0101),'' dated November 29, 2021. However, in staff 
requirements memorandum (SRM)-SECY-21-0098, ``Proposed Rule: Advanced 
Nuclear Reactor Generic Environmental Impact Statement (RIN 3150-AK55; 
NRC 2020-0101),'' dated April 17, 2024, the Commission directed the NRC 
staff to change the applicability of the GEIS and rule from ``advanced 
nuclear reactors'' to any new nuclear reactor application that meets 
the values and assumptions of the plant parameter envelopes and the 
site parameter envelopes used to develop the GEIS. Based on the 
direction from the Commission, the draft GEIS and proposed rule would 
be applicable to any new nuclear reactor, as defined in 10 CFR 50.2, 
``Definitions,'' that meets the values and assumptions of the plant 
parameter envelopes and the site parameter envelopes used to develop 
the GEIS.
    The NRC has also retitled this rulemaking from ``Advanced Nuclear 
Reactor Generic Environmental Impact Statement'' (ANR GEIS) to 
``Generic Environmental Impact Statement for Licensing of New Nuclear 
Reactors'' (NR GEIS), to reflect the change in the applicability of the 
GEIS and rule.

III. Discussion

A. Proposed Amendments

    The proposed amendments to 10 CFR part 51 would establish new 
requirements for environmental reviews of applications for an early 
site or construction permit or an operating or a combined license for 
new nuclear reactors.
    Specifically, the proposed amendments would codify the generic 
conclusions of the draft NR GEIS for those issues for which a generic 
conclusion regarding the potential environmental impacts of issuing a 
permit or license for a new nuclear reactor can be reached. These 
issues are identified as Category 1 issues in the NR GEIS. Similar to 
the NUREG-1437, the Category 1 issues identified and described in the 
NR GEIS may be applied to any new nuclear reactor application and have 
been determined to have a SMALL impact or significance level. The 
proposed appendix C, ``Environmental Effect of Issuing a Permit or 
License for a New Nuclear Reactor,'' to subpart A of 10 CFR part 51 
summarizes the Commission's findings for all Category 1 issues. In 
addition, the proposed amendments provide an applicant for a new 
nuclear reactor with the option to use the NR GEIS, including the 
reliance upon its generic analyses and the Category 1 findings.
    In this regard, an applicant can rely upon a given generic or 
Category 1 finding if it can demonstrate that the design of its 
proposed nuclear reactor and the parameters of the proposed site meet 
or are bounded by the values and assumptions of the NR GEIS analysis 
supporting that Category 1 finding. For each Category 1 issue, each 
supporting value and assumption is further classified as being part of 
the plant parameter envelope (PPE) or the site parameter envelope 
(SPE). The PPE consists of those values and assumptions relating to the 
design and operation of the nuclear reactor, such as building height, 
water use, air emissions, employment levels, and noise generation 
levels. The SPE consists of those values and assumptions relating to 
the siting of the plant, such as the site size, size of water bodies 
supplying water to the reactor, and demographics of the region 
surrounding the site. The NR GEIS provides the analysis evaluating the 
environmental impacts of a proposed nuclear reactor that fits within 
the bounds of the PPE on a site that fits within the bounds of the SPE. 
By using this approach, impact analyses for the environmental issues 
common to many new reactors can be addressed generically, thereby 
eliminating the need to repeatedly reproduce the same analyses each 
time a licensing application is submitted and allowing applicants and 
the NRC staff to focus future environmental review efforts on issues 
that only can be resolved once a site and facility are identified.
    Thus, if an applicant can demonstrate that the proposed nuclear 
reactor or the proposed site meets or is bounded by these PPE/SPE 
values and assumptions, then the applicant can adopt the conclusions of 
that Category 1 finding without having to conduct a project-specific 
analysis in its environmental report. Conversely, if an applicant 
cannot demonstrate that the proposed nuclear reactor or the proposed 
site meets or is bounded by these values and assumptions, or if the 
applicant determines that there is new and significant information 
regarding that Category 1 issue,\22\ then the applicant cannot adopt 
the conclusions of that Category 1 finding. In such case, the applicant 
would then have to prepare a project-specific analysis for that issue 
in its environmental report.
---------------------------------------------------------------------------

    \22\ The proposed amendments would require the applicant, for 
each Category 1 finding that it relies upon in preparing its 
environmental report, to describe the process it used to determine 
whether there is any new and significant information that may change 
that Category 1 issue's generic analysis or finding. This proposed 
requirement is modeled after the requirement in Sec.  
51.50(c)(1)(iv) that has been used for new reactor combined license 
applications that referenced an early site permit.
---------------------------------------------------------------------------

    Likewise, in preparing its draft SEIS, the NRC staff would rely 
upon those Category 1 findings for which the applicant has demonstrated 
meeting or being bounded by the underlying values and assumptions and 
would likewise not be required to include a project-specific analysis 
within the draft SEIS, unless the NRC staff became aware of new and 
significant information regarding that Category 1 issue. The Category 1 
findings in proposed table C-1 to appendix C, ``Summary of Findings on 
Environmental Issues for Issuing a Permit or License for a New Nuclear 
Reactor,'' can only be challenged in an individual ASLB licensing 
proceeding if a waiver is granted by the Commission in accordance with 
Sec.  2.335(b).
    The NR GEIS also identifies and describes environmental issues for 
which a generic finding regarding the respective environmental impacts 
cannot be reached because the issue requires the consideration of 
project-specific information that can only be evaluated once the 
proposed site and facility are identified. The NRC classifies these 
issues as Category 2 issues in the NR GEIS and within the proposed 
amendments. The NRC staff will prepare a project-specific analysis in 
the draft SEIS for each Category 2 issue, and for each Category 1 issue 
that the applicant cannot demonstrate that its project has met the 
underlying values and assumptions or for which there is

[[Page 80803]]

new and significant information. The draft SEIS will also include the 
NRC staff's preliminary conclusions regarding the potential 
environmental impacts for each of these issues.
    Two additional issues are designated as non-applicable (N/A) (i.e., 
impacts are uncertain) in the NR GEIS, in that a classification of the 
issue as either Category 1 or 2 is not possible. These issues relate to 
human health effects from exposure to electromagnetic fields (EMFs) 
during both construction and operation. Because the state of the 
science is currently inadequate, no generic conclusion on human health 
impacts is possible for these issues. If, in the future, the Commission 
finds that a general agreement has been reached by appropriate Federal 
health agencies that there are adverse health effects from EMFs, the 
Commission will require applicants to submit plant-specific reviews of 
these health effects as part of their application. The proposed 
amendments do not require applicants to submit information on these 
issues in the environmental report nor will the NRC staff prepare a 
plant-specific analysis for these issues in the draft SEIS.
    The NRC wishes to emphasize the importance of the public commenting 
at this time on environmental analyses set forth in the NR GEIS, on the 
NRC's classification of the potential environmental impacts of the 
construction, operation and decommissioning of a new nuclear reactor as 
either a generic (Category 1) or project-specific (Category 2) issue 
for each of the issues identified in the NR GEIS, and on the proposed 
rule changes that would codify the generic findings of the NR GEIS. 
After a final rule is published and effective, challenging the NRC's 
reliance upon a Category 1 issue in an individual new nuclear reactor 
permitting or licensing action will be prohibited except through an 
approved waiver in accordance with Sec.  2.335(b). On a 10-year cycle, 
the Commission intends to review the material in this GEIS and the 
associated rule and update it if necessary.

B. The Fiscal Responsibility Act of 2023

    The NRC acknowledges recent amendments to the NEPA statute in the 
Fiscal Responsibility Act of 2023 (Pub. L. 118-5, 137 Stat. 10) (FRA).
    The FRA added to NEPA a new section 107(e), which establishes page 
limits for environmental impact statements, including 300 pages for 
environmental impact statements for agency actions of ``extraordinary 
complexity'' (not including appendices, citations, figures, tables, and 
other graphics). The NRC finds that, to the extent that section 107(e) 
applies to the NR GEIS, a 300-page limit is appropriate because the NR 
GEIS addresses a proposed action of ``extraordinary complexity'' in 
light of the complicated systems, structures, and components deployed 
in operating nuclear power plants; the number of resource areas 
addressed; and the variety of environments in which nuclear power 
plants operate. The draft NR GEIS is less than 300 pages and therefore 
complies with the NEPA page limits.

C. Environmental Impacts To Be Reviewed

    In the draft NR GEIS, the NRC has preliminarily made generic 
findings that many of the potentially adverse environmental impacts of 
constructing, operating, and decommissioning a new nuclear reactor will 
be SMALL provided that the applicant's proposed nuclear reactor and the 
proposed site meets or is bounded by the respective values and 
assumptions supporting the Category 1 finding under consideration. See 
Section III.C., ``Environmental Impacts to be Reviewed,'' of this 
document for a more detailed discussion of the process used in the NR 
GEIS.
    The NRC divided its conclusions about environmental impacts in the 
NR GEIS into the following three categories:
     Category 1. Environmental issues for which the NRC has 
been able to make a generic finding of SMALL adverse environmental 
impacts, or beneficial impacts, provided that the applicant's proposed 
reactor facility and site meet or are bounded by the relevant values 
and assumptions in the PPE and SPE that support the generic finding for 
that Category 1 issue.\23\
---------------------------------------------------------------------------

    \23\ Beneficial impacts may include increased tax revenues 
associated with the increased assessed value of new reactor 
projects, and other economic activity such as increases in local 
employment, labor income, and economic output.
---------------------------------------------------------------------------

     Category 2. Environmental issues for which a generic 
finding regarding the environmental impacts cannot be reached because 
the issue requires the consideration of project-specific information 
that can only be evaluated once the proposed site is identified. The 
impact significance (i.e., SMALL, MODERATE, or LARGE) \24\ for these 
issues will be determined in a project-specific evaluation.
---------------------------------------------------------------------------

    \24\ See Section II.B. of this document for a description of the 
SMALL, MODERATE, and LARGE significance levels used by the NRC in 
its EISs.
---------------------------------------------------------------------------

     Not Applicable (N/A). Environmental issues for which the 
state of the science is currently inadequate, and no generic conclusion 
on human health impacts is possible.
    In the NR GEIS, the NRC identifies a total of 122 environmental 
issues that may be associated with constructing, operating, and 
decommissioning a new nuclear reactor; of these issues, the NRC 
identified 100 environmental issues as Category 1 issues. Chapter 3, 
``Affected Environment and Environmental Consequences,'' of the NR GEIS 
provides the analyses supporting the generic finding of a SMALL 
significance level impact for each Category 1 issue and indicates the 
relevant values and assumptions in the PPE and SPE underlying the 
analyses. Applicants and the NRC staff may rely on the generic finding 
for each Category 1 issue, as codified in proposed table C-1, provided 
that the applicant's proposed reactor facility and the proposed site 
meet or are bounded by the relevant values and assumptions for that 
Category 1 issue and that there is no new and significant information 
that changes the issue's generic analysis or finding, as determined by 
the NRC.
    The NR GEIS identifies 20 environmental issues as Category 2 
issues. These issues cannot be evaluated generically and must be 
evaluated by the applicant, in its environmental report, and the NRC 
staff, in the draft SEIS, using project-specific information. For 
example, the Endangered Species Act of 1973 (ESA) requires every 
Federal agency to consult with the ``Service'' \25\ and document its 
consideration of the impacts of its actions on threatened and 
endangered species and critical habitats. The NRC typically conducts 
this ESA analysis in parallel with its NEPA process.
---------------------------------------------------------------------------

    \25\ Depending on the species impacted, the agency will consult 
with either the U.S. Fish & Wildlife Service (U.S. Department of the 
Interior) or the National Marine Fisheries Service (U.S. Department 
of Commerce), as provided in the Services' joint regulations at 50 
CFR part 402, ``Interagency Cooperation--Endangered Species Act of 
1973, as Amended.''
---------------------------------------------------------------------------

    Finally, for two environmental issues, the NR GEIS identifies the 
category as N/A. The two issues concern the potential exposure to EMFs 
from construction and operation. Studies of 60 Hertz (Hz) EMFs have not 
uncovered consistent evidence linking harmful effects with field 
exposures. Because the state of the science is currently inadequate, no 
generic conclusion on human health impacts is possible. If, in the 
future, the Commission finds that a general agreement has been reached 
by appropriate Federal health agencies that there are adverse health 
effects from EMFs regarding these two issues, the Commission will then 
treat the issue in a manner similar to a Category 2 issue and require 
applicants to submit

[[Page 80804]]

project-specific reviews of these health effects in their environmental 
report. Until such time, applicants are not required to submit 
information on these issues.

D. Generic Environmental Impact Statement

    The purpose of the NR GEIS is to present impact analyses for the 
environmental issues common to many new nuclear reactors that can be 
addressed generically, thereby eliminating the need to repeatedly 
reproduce the same analyses each time a licensing application is 
submitted and allowing applicants and NRC staff to focus future 
environmental review efforts on issues that can only be resolved once a 
site is identified. The NR GEIS is intended to improve the efficiency 
of licensing new nuclear reactors by: (1) identifying the types of 
potential environmental impacts of constructing, operating, and 
decommissioning a new nuclear reactor, (2) assessing impacts that are 
expected to be generic (the same or similar) for many new nuclear 
reactors (Category 1 issues), and (3) defining the environmental issues 
that will need to be addressed in project-specific SEISs (Category 2 
issues). The NRC staff has preliminarily concluded in the draft NR GEIS 
that the potential environmental impacts will be beneficial or of a 
SMALL adverse significance level for Category 1 issues.
    In the NR GEIS, the NRC staff evaluated the impacts of 
constructing, operating, and decommissioning a new nuclear reactor 
sited within the United States that meets or is bounded by the values 
and assumptions in the PPE and SPE for each Category 1 issue. The term 
``building,'' as used in the NR GEIS, includes the full range of 
preconstruction activities (e.g., site grading) and NRC-authorized 
``construction'' activities.\26\ Further, for purposes of the NR GEIS, 
the NRC staff assumed that the U.S. Army Corps of Engineers would be a 
cooperating agency, in accordance with the memorandum of understanding 
(MOU) between the two agencies dated September 12, 2008.\27\ In this 
regard, the U.S. Army Corps of Engineers has been a cooperating agency 
since the MOU was signed in 2008. In addition, the NR GEIS considered 
fuel cycle impacts and the impacts from continued storage of spent 
fuel, including incorporating by reference the NRC's NUREG-2157, as 
further described below.
---------------------------------------------------------------------------

    \26\ The NRC has regulatory authority over those construction 
activities that are related to radiological health and safety, 
physical security, or otherwise pertain to radiological controls. 
The NRC defines these activities as ``construction'' in Sec.  51.4, 
``Definitions.'' As stated in Sec.  51.45(c) preconstruction is 
defined as those activities listed in Sec.  51.4(1)(ii).
    \27\ The MOU between the NRC and the U.S. Army Corps of 
Engineers, dated September 12, 2008, is available in ADAMS under the 
accession number ML082540354.
---------------------------------------------------------------------------

    Because there may be multiple new nuclear reactor designs and a new 
nuclear reactor could be sited anywhere in the United States that meets 
the NRC siting requirements in 10 CFR part 100, ``Reactor Site 
Criteria,'' the NRC applied a technology-neutral, performance-based 
approach using a PPE. The PPE consists of parameters for specific 
reactor design features regardless of the site. Examples of parameters 
include the permanent footprint of disturbance, building height, water 
use, air emissions, employment levels, and noise generation levels. For 
each PPE parameter, the NRC staff developed a set of bounding values 
and assumptions that if met, and absent any new and significant 
information, would demonstrate that the potential environmental impacts 
for that PPE parameter would be SMALL.
    In addition, the NRC staff developed a set of site-related 
parameters termed the SPE. Examples of parameters include site size, 
size of water bodies supplying water to the reactor, and demographics 
of the region surrounding the site. For each SPE parameter, the NRC 
staff developed a set of bounding values and assumptions related to the 
condition of the affected environment, such as the extent and 
occurrence of nearby bodies of water, wetlands and floodplains, and 
proximity to sensitive noise receptors. Similar to a PPE parameter, if 
an applicant can demonstrate that the proposed reactor site meets the 
SPE parameter's bounding values and assumptions, and absent any new and 
significant information, then the potential environmental impacts for 
that SPE parameter would be SMALL. Under this proposed rule, a proposed 
reactor site would be determined to meet a given Category 1 issue if 
the applicant has demonstrated that it has met the bounding values and 
assumptions of each PPE and SPE parameter relevant to that Category 1 
issue and that there is no new and significant information.
    The PPE and SPE values and assumptions in the NR GEIS were 
developed by an interdisciplinary team of subject matter experts (SMEs) 
assigned to prepare the NR GEIS. The SMEs developed the values and 
assumptions based on one or more criteria, as described in the NR GEIS.
    The NR GEIS identifies specific types of potential environmental 
impacts for 16 environmental resource areas: land use, visual 
resources, meteorology and air quality, water resources (surface and 
groundwater), terrestrial ecology, aquatic ecology, historic and 
cultural resources, environmental hazards (radiological and 
nonradiological), noise, waste management (radiological and 
nonradiological), postulated accidents, socioeconomics, environmental 
justice, fuel cycle, transportation of fuel and waste, and 
decommissioning. Each resource area includes one or more types of 
potential impacts, and each type of potential impact is termed an 
issue. In addition to the 16 environmental resource areas, the NRC 
staff considered climate change, cumulative impacts, purpose and need, 
need for power, site alternatives, energy alternatives, and system 
design alternatives. Each of the 122 issues that were identified 
corresponds to a specific type of environmental impact determined by 
the interdisciplinary team of SMEs that could potentially result from 
construction, operation, or decommissioning of a new nuclear reactor. 
For each issue, the SMEs then determined whether it would be possible 
to identify values and assumptions in the PPE and SPE that could 
effectively bound a meaningful generic analysis and provided the basis 
for each value and assumption. The SMEs then performed and described 
their generic analyses for each issue, for a hypothetical reactor/site 
that meets the PPE and SPE values and assumptions in the NR GEIS. The 
values and assumptions were set such that the SMEs could reach a 
generic conclusion of SMALL adverse impacts, and the issue was then 
designated as a Category 1 issue. Issues for which the potential 
impacts are beneficial were also designated as Category 1. Issues for 
which the NRC staff could not reach a generic conclusion regarding 
impacts were designated as Category 2 issues. In addition, two issues 
were placed in the category of N/A because the state of the science is 
currently inadequate, and no generic conclusion on human health impacts 
is possible.
    An applicant addressing a Category 1 issue in its environmental 
report may refer to the generic analysis in the NR GEIS for that issue 
and rely upon the generic finding of a SMALL significance level, 
without further analysis, provided that it demonstrates that the 
relevant values and assumptions of the PPE and SPE used in the resource 
analysis are met and there is no new and significant information that 
would require project-specific analysis. The applicant will

[[Page 80805]]

have to document how the proposed reactor facility and the proposed 
site meet or are bounded by the applicable values and assumptions for 
that Category 1 issue and describe the process it used to determine 
whether there is any new and significant information that may change 
that Category 1 issue's generic analysis or finding. The extent of the 
information necessary to demonstrate that the applicant's project meets 
or is bounded by a given value or assumption will vary. In some cases, 
the demonstration may only require showing that the project falls 
within a parameter value or assumption (e.g., building height). But in 
other cases, analysis may be required to demonstrate that a value or 
assumption has been met (e.g., noise levels).
    In its environmental report, the applicant would have to supply the 
requisite information necessary for the NRC staff to perform a project-
specific analysis for (1) Category 1 issues for which the relevant 
values and assumptions are not met, or for which new and significant 
information was identified, and (2) all Category 2 issues. Guidance for 
applicants providing information to the NRC staff in an environmental 
report is available in RG 4.2, ``Preparation of Environmental Reports 
for Nuclear Power Stations.'' If a project-specific analysis is 
required for a Category 1 issue, the applicant may be able to 
incorporate by reference all or part of the generic analysis provided 
in the NR GEIS as a part of its analysis and focus on providing any 
additional project-specific information needed to support its 
conclusion.
    After the applicant submits its environmental report, the NRC staff 
will prepare the draft SEIS, and following the public comment period, 
the final SEIS. When considering a Category 1 issue in a SEIS, the NRC 
staff will likewise refer to the generic analysis in the NR GEIS for 
that issue without further analysis, provided that the relevant values 
and assumptions in the PPE and SPE are met and there is no new and 
significant information that changes the generic finding for that 
Category 1 issue. The NRC staff also will document that the applicant 
has demonstrated that the values and assumptions are met for that 
issue. The NRC staff will complete a project-specific analysis in 
accordance with the latest version of the Environmental Standard Review 
Plan or related guidance (such as any relevant interim staff guidance) 
for (1) Category 1 issues for which the relevant values and assumptions 
are not met, or for which new and significant information was 
identified, and (2) all Category 2 issues. If a project-specific 
analysis is required for a Category 1 issue, the NRC staff may be able 
to incorporate by reference all or part of the generic analysis 
provided in the NR GEIS as a part of its analysis and focus on 
providing any additional project-specific information needed to support 
its conclusion.

E. Summary of Issues Analyzed in the NR GEIS

    The following describes those environmental issues that were 
examined for the NR GEIS and summarizes the conclusions by resource 
area. The determination that an applicant can rely on the finding for a 
Category 1 issue assumes that the applicant can demonstrate that its 
proposed reactor facility and the proposed site meet or is bounded by 
all the respective values and assumptions of that Category 1 issue, and 
further, that there is no new and significant information related to 
that issue.
1. Land Use
    The NRC staff evaluated the potential impacts to onsite and offsite 
land use for both construction and operation. In addition, the NRC 
staff considered the impacts of the project in accordance with the 
Coastal Zone Management Act and the Farmland Protection Policy Act, if 
applicable. The NRC staff concluded that all identified issues can be 
classified as Category 1 issues.
2. Visual Resources
    The NRC staff evaluated the potential visual impacts in the site 
and vicinity and along the transmission lines for both the construction 
and operation. The NRC staff concluded that all identified issues can 
be classified as Category 1 issues.
3. Meteorology and Air Quality
    The NRC staff evaluated the potential air quality impacts from the 
emissions of criteria pollutants, dust and hazardous pollutants, and 
greenhouse gas emissions for both construction and operation. In 
addition, the NRC staff considered the potential operations-related air 
quality impacts from cooling-system emissions and the emission of ozone 
and nitrogen oxides during transmission line operations. The NRC staff 
concluded that all identified issues can be classified as Category 1 
issues.
4. Water Resources
    The NRC staff evaluated the potential impacts to water use and 
water quality for both surface water and groundwater for both 
construction and operation. The NRC staff concluded that all identified 
issues can be classified as Category 1 issues, with one exception. The 
NRC staff determined that surface water quality degradation due to 
chemical and thermal discharges could not be resolved generically 
because there was no practical way to develop a comprehensive bounding 
set of water quality criteria, including both thermal and chemical 
criteria, for the PPE and SPE. Therefore, this issue is a Category 2 
issue, and thus requires a project-specific evaluation.
5. Terrestrial Ecology
    The NRC staff evaluated the potential impacts to terrestrial 
wildlife, habitats, and wetlands for both construction and operation. 
The NRC staff concluded that all identified issues can be classified as 
Category 1 issues, with two exceptions. The NRC staff determined that 
the potential impacts to wildlife regulated under the ESA could not be 
generically resolved for either construction or operations because the 
NRC staff would need to consult individually with the U.S. Fish and 
Wildlife Service under ESA Section 7 regarding the potential effects of 
each specific licensing action. Therefore, these issues are Category 2 
issues, and thus require a project-specific evaluation.
6. Aquatic Ecology
    The NRC staff evaluated the potential impacts to aquatic wildlife 
and habitats for both construction and operation. The NRC staff 
concluded that all identified issues can be classified as Category 1 
issues, with four exceptions. The NRC staff determined that the 
potential impacts to resources regulated under the ESA and the 
Magnuson-Stevens Fishery Conservation and Management Act could not be 
generically resolved for either construction or operations because the 
NRC staff would need to consult individually with the U.S. Fish and 
Wildlife Service and/or the National Marine Fisheries Service under ESA 
Section 7 and the Magnuson-Stevens Act regarding the potential effects 
of each specific licensing action. In addition, the NRC staff 
determined that potential thermal impacts on aquatic biota and other 
potential effects of cooling-water discharges on aquatic biota could 
not be resolved generically. For both of these issues, the NRC staff 
would have to first review the discharge plume analysis and the aquatic 
biota potentially present before being able to reach a conclusion 
regarding the possible significance of impacts on the biota. Therefore, 
these four issues are Category 2 issues, and thus require project-
specific evaluations.

[[Page 80806]]

7. Historic and Cultural Resources
    Both construction and operation of a new nuclear reactor have the 
potential to affect historic and cultural resources. The NRC staff 
would need to complete a project-specific consultation in accordance 
with Section 106 of the National Historic Preservation Act as part of 
its environmental review. Therefore, these two issues are Category 2 
issues, and thus require project-specific evaluations.
8. Environmental Hazards
    This resource area encompasses both radiological impacts and 
nonradiological impacts. The NRC staff evaluated the potential impacts 
of environmental hazards for both construction and operation. The NRC 
staff concluded that all identified issues can be classified as 
Category 1 issues, with two exceptions. These two issues are the human 
health impacts of EMFs for both construction and operation. The NRC 
staff determined that because the state of the science regarding the 
human health impacts of EMFs is currently inadequate, no generic 
conclusion on those impacts is possible, and has classified these 
issues as N/A. If, in the future, the Commission finds that a general 
agreement has been reached by appropriate Federal health agencies that 
there are adverse health effects from EMFs, the Commission will require 
applicants to submit plant-specific reviews of these health effects as 
part of their application. Until such time, applicants are not required 
to submit information on this issue.
9. Noise
    The NRC staff evaluated the potential impacts of noise for both 
construction and operation. The NRC staff concluded that all identified 
issues can be classified as Category 1 issues.
10. Waste Management
    This resource area encompasses the potential impacts of both 
radiological waste management and nonradiological waste management. The 
NRC staff evaluated the potential operational impacts of radiological 
waste management. In addition, the NRC staff evaluated the potential 
impacts of nonradiological waste management for both construction and 
operation. The NRC staff concluded that all identified issues can be 
classified as Category 1 issues.
11. Postulated Accidents
    The NRC staff evaluated the potential operational impacts of 
postulated accidents (because these impacts occur only during 
operations). The NRC staff concluded that all identified issues can be 
classified as Category 1 issues, with one exception. The NRC staff 
determined that severe accidents are a Category 2 issue. Based on the 
analysis in the preliminary or final safety analysis report regarding 
severe accidents and probabilistic risk assessments, if a new nuclear 
reactor design has severe accident progressions that involve 
radiological or hazardous chemical releases, then a project-specific 
environmental risk evaluation must be performed.
12. Socioeconomics
    The NRC staff evaluated the potential impacts of socioeconomics for 
both construction and operation. The NRC staff concluded that these two 
issues can be classified as Category 1 issues.
13. Environmental Justice
    Both construction and operation may raise environmental justice 
issues. The NRC staff has determined that potential environmental 
justice impacts during construction or operations cannot be determined 
without the consideration of meaningful project-specific factors, and 
therefore, are Category 2 issues. Project-specific factors include the 
presence, geographic location, and size of specific minority or low-
income populations; impact pathways derived from the plant design, 
layout, or site characteristics; or other community characteristics 
affecting specific minorities or low-income populations.
14. Fuel Cycle
    The NRC staff evaluated the potential operational impacts of the 
fuel cycle (because these impacts do not occur during construction). 
The NRC staff concluded that all identified issues can be classified as 
Category 1 issues. However, because the values and assumptions do not 
encompass the potential fuel fabrication impacts for metal fuel and 
liquid-fueled molten salt, such fuels would require a project-specific 
analysis.
    The NR GEIS incorporates by reference NUREG-2157, in which the NRC 
evaluated the environmental impacts of the continued storage of spent 
nuclear fuel beyond the licensed life for the operation of light-water 
reactors (LWRs). In Sec.  51.23, the NRC specifies that NUREG-2157 is 
deemed to be incorporated into the EIS for a new reactor. However, 
NUREG-2157 did not evaluate the storage of spent nuclear fuel from non-
LWRs. The NRC staff expects that many new nuclear reactors will not be 
LWRs. The NR GEIS therefore evaluates the applicability of NUREG-2157 
and determines that the findings in NUREG-2157 are applicable to non-
LWR fuel, provided that the non-LWR fuel is stored in a manner that 
meets the regulatory requirements for spent fuel storage cask approval 
and fabrication in accordance with subpart L, ``Approval of Spent Fuel 
Storage Casks,'' to 10 CFR part 72.
15. Transportation
    The NRC staff evaluated the potential operational impacts of the 
transportation of fuel and waste to and from new nuclear reactors 
(because these impacts occur only during operations). The NRC staff 
concluded that all identified issues can be classified as Category 1 
issues.
16. Decommissioning
    The NRC staff previously evaluated the environmental impacts of the 
decommissioning of nuclear power reactors as residual radioactivity at 
the site is reduced to levels that allow for termination of the NRC 
license. This evaluation was documented in the ``Generic Environmental 
Impact Statement on Decommissioning of Nuclear Facilities'' 
(Decommissioning GEIS, NUREG-0586, Supplement 1). The NRC staff 
evaluated NUREG-0586, Supplement 1, and determined that its conclusions 
and analysis are applicable to new reactors in the NR GEIS. Therefore, 
for the purposes of the NR GEIS, the environmental impacts of 
decommissioning for certain resource areas that were generically 
addressed in NUREG-0586, would be limited to operational areas, would 
not be detectable or destabilizing, and are expected to have a 
negligible effect on the impacts of terminating operations and 
decommissioning.
    The issues for which these generic findings were made in the 
Decommissioning GEIS are designated as a Category 1 issue in the NR 
GEIS. However, certain issues in NUREG-0586, Supplement 1 were 
determined to require project-specific analysis and certain others to 
require project-specific analysis under certain conditions. These 
issues are therefore designated as Category 2 issues in the NR GEIS. 
NUREG-0586, Supplement 1, is incorporated into the NR GEIS.
17. Issues Applying Across Resources
    The NRC staff determined that the impacts related to climate change 
and the consideration of cumulative impacts could not be evaluated 
generically. As such, both of these issues have been classified as 
Category 2 issues and thus require a project-specific evaluation.

[[Page 80807]]

18. Non-Resource Related Category 2 Issues
    The NR GEIS addresses the environmental impact issues associated 
with constructing, operating, and decommissioning a new nuclear 
reactor. However, the environmental report and the NRC staff's SEIS 
must also include other information, as required by the regulations and 
discussed in regulatory guidance. These are not resource-specific 
issues. Rather, they are project-specific issues, not tied to any 
specific environmental resource, that are necessary to support the NRC 
staff's completion of its environmental review in accordance with NEPA. 
These issues cannot be evaluated generically and must be addressed in 
the environmental report and SEIS using project-specific information. 
In the NR GEIS, the NRC staff identified the following issues: purpose 
and need, need for power, site alternatives, energy alternatives, and 
system design alternatives. This list is not all-inclusive. NRC 
regulations at 10 CFR part 51 and guidance such as RG 4.2 describe 
information not included in this list that must be included as part of 
an application.

F. Public Comments on Notice of Exploratory Process and Notice of 
Intent To Prepare a Generic Environmental Impact Statement

    On November 15, 2019 (84 FR 62559), the NRC published in the 
Federal Register, ``Agency Action Regarding the Exploratory Process for 
the Development of an Advanced Nuclear Reactor Generic Environmental 
Impact Statement,'' announcing an exploratory process and soliciting 
comments to determine the possibility of developing a GEIS for 
licensing advanced nuclear reactors. The exploratory process included 
two public meetings, a public workshop attended by multiple 
stakeholders, and a site visit to the Idaho National Laboratory, a 
location that is being contemplated for construction and operation of 
advanced nuclear reactors.
    Advice and recommendations on the possibility of preparing an 
advanced nuclear reactor GEIS were invited from all interested persons. 
Comments were specifically requested on the whether the scope of the 
GEIS should include reactors regardless of technology or be limited to 
specific reactor technologies, what reactor sizes (footprint) and power 
levels should be included in the scope of the GEIS, whether the 
geographical site of a reactor should be considered in developing the 
scope of the GEIS, and whether a set of bounding plant parameters 
should be consider in developing the scope of the GEIS, and if so, what 
parameters should be considered.
    The NRC received comments that both supported and opposed the 
development of an advanced nuclear reactor GEIS. Commenters who 
supported development of an advanced nuclear reactor GEIS stated that 
it would improve the efficiency of the environmental review process, 
would avoid duplication of effort, and would focus future reviews on 
important environmental issues. Commenters who did not support 
development of an advanced nuclear reactor GEIS stated that the GEIS 
would be premature at this time and that the NRC staff did not have 
sufficient information available to resolve issues generically. Based 
on the results of the exploratory process, the NRC staff concluded that 
there was sufficient information to complete an advanced nuclear 
reactor GEIS which would generically resolve many environmental issues, 
save resources for individual reviews, and provide predictability for 
potential applicants in developing their applications. The results of 
the exploratory process were summarized in SECY-20-0020, ``Results of 
Exploratory Process for Developing a Generic Environmental Impact 
Statement for the Construction and Operation of Advanced Nuclear 
Reactors,'' issued on February 28, 2020.
    On April 30, 2020 (85 FR 24040), the NRC published in the Federal 
Register, ``Notice To Conduct Scoping and Prepare an Advanced Nuclear 
Reactor Generic Environmental Impact Statement.'' Advice and 
recommendations on the scope of the GEIS were invited from all 
interested persons.
    Comments were requested regarding the parameters that the NRC 
should use to bound the advanced nuclear reactors in the PPE (including 
power level and size of the site) and the parameters that should be 
used to bound the affected environment in the SPE. In addition, 
comments were requested on resources or issues that could be resolved 
generically and ones that could not.
    The NRC received comments concerning the NEPA process, the PPE and 
SPE, hydrology, socioeconomics, environmental justice, historic and 
cultural resources, climate change, radiological health, uranium fuel 
cycle, accidents, transportation of spent fuel, and need for power. The 
NRC also received general comments in support of and opposition to the 
advanced nuclear reactor GEIS, and comments concerning issues outside 
the scope of the GEIS. A summary of comments and the NRC staff response 
are available in the scoping summary report issued on September 25, 
2020, which is available as indicated in the ``Availability of 
Documents'' section of this document.

G. Clarifying Amendment for Postoperating Licenses

    The NRC is proposing to add to Sec. Sec.  51.53(d) a cross-
reference to the license termination provisions under Sec.  52.110, 
``Termination of license.'' This change will clarify in Sec.  51.53(d) 
that NRC's requirements at 10 CFR part 52 also include license 
termination provisions.

IV. Specific Requests for Comment

    The NRC is seeking public comment on this proposed rule, the NR 
GEIS, draft regulatory guide (DG), DG-4032, ``Preparation of 
Environmental Reports for Nuclear Power Stations,'' and draft Interim 
Staff Guidance COL-ISG-030, ``Environmental Considerations Associated 
with New Nuclear Reactor Applications that Reference the Generic 
Environmental Impact Statement (NUREG-2249).'' In addition, the NRC 
staff developed two draft documents referenced in DG-4032, the ``Energy 
and System Design Mitigation Alternatives White Paper'' (``White 
Paper'') and ``Recommendations for an Applicant to Calculate Activity 
Data for Greenhouse Gases Estimates'' (``GHG Estimates''). These 
documents are references to DG-4032 and, therefore, are open to review 
and comment from the public. The DG-4032, COL ISG-030, the White Paper, 
and the GHG Estimates document are described in Section XIV, 
``Availability of Guidance,'' of this document.
    Further, the NRC staff is particularly interested in comments and 
supporting rationale from the public on the following:
    1. Plant parameter envelope and site parameter envelope values and 
assumptions: If a commenter believes the NRC staff is using an 
inappropriate value to result in a SMALL impact (either too 
restrictive, or not restrictive enough), explain the basis for that 
position and provide an alternative proposed parameter value.
    2. Environmental issues evaluated: Are there any environmental 
issues that the NRC staff did not include in the scope of the NR GEIS 
and the proposed rule that should be included? Commenters should 
provide the basis for considering any proposed environmental issues.
    3. Categorization of issues: Are the environmental issues 
categorized appropriately? In other words, are there Category 1 issues 
that should be Category 2, or Category 2 issues that

[[Page 80808]]

should be Category 1? Provide a basis for such conclusions.
    4. Scope of proposed rule changes and GEIS: Is the applicability of 
the GEIS to new reactors (which includes advanced nuclear reactors) 
clearly articulated? Do the proposed revisions adequately address all 
licensing scenarios associated with evaluating the environmental 
impacts of permitting and licensing new nuclear reactor construction 
and operation? For example, no changes are proposed to Sec.  51.53(b), 
``Post-construction environmental report-operating license stage,'' 
because this provision already references the requirements of Sec.  
51.50, ``Environmental report--construction permit, early site permit, 
or combined license stage,'' which is modified by the proposed rule. 
Commenters should clearly specify any proposed regulatory text 
additions or changes and provide the basis for such proposed changes.
    5. Guidance for applicants: Are the methods described in the draft 
revision to RG 4.2 for demonstrating values and assumptions 
appropriate? Describe and justify any methods that the commenter 
believes are not appropriate.
    6. Limited Work Authorizations: Should the NRC expand the NR GEIS 
and the rule to include NRC approval of limited work authorizations 
(LWAs) \28\ for new nuclear reactor applications? Specifically, should 
an LWA applicant that demonstrates that its proposed project meets or 
is bounded by the PPE and SPE values and assumptions for a given 
Category 1 issue be able to rely on the generic findings for that issue 
in preparing the environmental report that it will submit in support of 
its LWA application? Similarly, should the NRC be able to rely on the 
generic findings for that Category 1 issue in preparing its 
supplemental environmental impact statement? If the NRC were to expand 
the NR GEIS and the rule to include NRC approval of LWAs, the expansion 
would cover both LWAs submitted as a stand-alone application and an LWA 
request submitted in conjunction with an application for another form 
of NRC approval described in the NR GEIS and in the proposed rule 
(e.g., a construction permit application).
---------------------------------------------------------------------------

    \28\ A LWA permits a nuclear power plant applicant to engage in 
certain reactor construction activities before the NRC issues a 10 
CFR part 50 construction permit or a 10 CFR part 52 combined 
license. The applicable NRC regulations for LWAs include Sec. Sec.  
50.10, ``License required; limited work authorization;'' 52.1(a); 
52.17(c); 52.24, ``Issuance of early site permit;'' 52.27, ``Limited 
work authorization after issuance of early site permit;'' 52.80, 
``Contents of applications; additional technical information;'' and 
52.91, ``Authorization to conduct limited work authorization 
activities.'' The NRC last amended its LWA regulations in 2007 (72 
FR 57416; October 9, 2007).
---------------------------------------------------------------------------

V. Section-by-Section Analysis

    The following paragraphs describe the specific changes proposed by 
this rulemaking.

Section 51.50, Environmental Report--Construction Permit, Early Site 
Permit, or Combined License Stage

    The NRC proposes to amend paragraph (a) by adding a new second 
sentence regarding the requirement for non-LWR applicants to address 
fuel cycle impacts, making this paragraph consistent with the existing 
language in paragraphs (b) and (c).
    The NRC proposes to add a new paragraph (d) to permit the use of 
the NR GEIS for an application for a construction permit, early site 
permit, or combined license for a new nuclear reactor.

Section 51.53, Postconstruction Environmental Reports

    The NRC proposes to amend the first sentence of paragraph (d) by 
adding ``Sec.  52.110'' to reflect that 10 CFR part 52 also includes 
license termination provisions.

Section 51.75, Draft Environmental Impact Statement--Construction 
Permit, Early Site Permit, or Combined License

    The NRC proposes to add a new paragraph (d) to provide direction on 
the preparation of a draft supplemental environmental impact statement 
for an application that makes use of the NR GEIS for a construction 
permit, early site permit, or combined license for a new nuclear 
reactor.

Section 51.96, Final Supplemental Environmental Impact Statement 
Relying on Appendix C to Subpart A

    The NRC proposes to add a new section to provide direction on 
preparation of a final supplemental environmental impact statement for 
a new nuclear reactor application that relied on any of the findings in 
appendix C to subpart A of this part in preparing a draft supplemental 
environmental impact statement in accordance with Sec.  51.75(d).

Appendix C to Subpart A, Environmental Effect of Issuing a Permit or 
License for a New Nuclear Reactor

    The NRC proposes to add appendix C to add a table to codify the NR 
GEIS findings and to specify values and assumptions that need to be met 
by the applicant to incorporate Category 1 conclusions into the 
environmental report and identify the Category 2 and uncategorized 
issues that need to be evaluated on a project-specific basis. Proposed 
appendix C states that, on a 10-year cycle, the Commission intends to 
review the material in this appendix and update it if necessary.

VI. Regulatory Flexibility Certification

    The Regulatory Flexibility Act of 1980 (RFA), as amended at 5 
U.S.C. 601 et seq., requires that agencies consider the impact of their 
rulemakings on small entities and, consistent with applicable statutes, 
consider alternatives to minimize these impacts on the businesses, 
organizations, and government jurisdictions to which they apply.
    In accordance with the Small Business Administration's regulation 
at 13 CFR 121.903(c), the NRC has developed its own size standards for 
performing an RFA analysis and has verified with the SBA Office of 
Advocacy that its size standards are appropriate for NRC analyses. The 
NRC size standards at 10 CFR 2.810, ``NRC size standards,'' are used to 
determine whether an applicant or licensee qualifies as a small entity 
in the NRC's regulatory programs. Section 2.810 defines the following 
types of small entities:
    small business is a for-profit concern and is a--(1) Concern that 
provides a service or a concern not engaged in manufacturing with 
average gross receipts of $8.0 million or less over its last 5 
completed fiscal years; or (2) Manufacturing concern with an average 
number of 500 or fewer employees based upon employment during each pay 
period for the preceding 12 calendar months.
    small organization is a not-for-profit organization which is 
independently owned and operated and has annual gross receipts of $8.0 
million or less.
    small governmental jurisdiction is a government of a city, county, 
town, township, village, school district, or special district with a 
population of less than 50,000.
    small educational institution is one that is--(1) Supported by a 
qualifying small governmental jurisdiction; or (2) Not state or 
publicly supported and has 500 or fewer employees.

Number of Small Entities Affected

    The NRC is currently aware of no known small entities as defined in 
Sec.  2.810 that are planning to apply for a new nuclear reactor 
construction permit or operating license under 10 CFR part 50 or an 
early site permit or combined license under 10 CFR part 52, which would 
be impacted by this proposed

[[Page 80809]]

rule. Based on this finding, the NRC has preliminarily determined that 
the proposed rule would not have a significant economic impact on a 
substantial number of small entities.

Economic Impact on Small Entities

    Depending on how the ownership and/or operating responsibilities 
for such an enterprise were structured, applicants for a new nuclear 
reactor rated 8 megawatts electric (MWe) or less could conceivably meet 
the definition of small entities as defined by Sec.  2.810. Owners that 
operate power reactors rated greater than 8 MWe could generate 
sufficient electricity revenue that exceeds the gross annual receipts 
limit of $7 million, assuming a 90 percent capacity factor and the 2023 
U.S. Department of Energy's Energy Information Administration U.S. 
average price of electricity to the ultimate customer for all sectors 
of 12.7 cents per kilowatt-hour. \29\
---------------------------------------------------------------------------

    \29\ https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=epmt_5_03.
---------------------------------------------------------------------------

    Although the NRC is not aware of any small entities that would be 
affected by the proposed rule, there is a possibility that future 
applications for a new nuclear reactor permit or license could be 
submitted by small entities who plan to own and operate a nuclear 
reactor rated 8 MWe or less. Nuclear reactors that are rated 8 MWe or 
less would most likely be used to support electrical demand for 
military bases, small remote towns, and process heat and would not 
directly compete with larger nuclear reactors that typically produce 
electricity for the grid. As a result of these differing purposes, the 
NRC would expect that small and large entities would not be in direct 
competition with each other.
    Regulations at Sec.  171.16(c) allow for certain NRC licensees to 
pay reduced annual fees if they qualify as small entities, although 
these regulations do not include licensees authorized to conduct 
activities under either 10 CFR part 50 or 10 CFR part 52. However, 
should a small entity apply for a nuclear reactor license or permit, 
the small entity could request a one-time fee exemption. In subsequent 
years, the NRC licensee could submit a new request for a fee exemption 
for each fiscal year for which it desires an exemption. Additionally, 
after the small entity receives an operating license under 10 CFR part 
50 or under part 52 and has completed power ascension testing, the 
small entity would be eligible for a reduced annual fee under Sec.  
171.15, ``Annual fees: Non-power production or utilization licenses, 
reactor licenses, and independent spent fuel storage licenses,'' based 
on the cumulative licensed thermal power rating of the reactor. The 
fiscal year 2023 annual fee for each large operating power reactor is 
$5,492,000.
    Therefore, the NRC preliminarily concludes that this proposed rule 
would not have a significant economic impact on a substantial number of 
small entities.

Request for Comments

    The NRC is seeking comments on both its initial RFA analysis and on 
its preliminary conclusion that this proposed rule would not have a 
significant economic impact on a substantial number of small entities 
because of the likelihood that most expected applicants would not 
qualify as a small entity. Additionally, the NRC is seeking comments on 
its preliminary conclusion that if a small entity were to submit a new 
nuclear reactor application, the small entity would not incur a 
significant economic impact as it would most likely not be in 
competition with a large entity.
    Any small entity that could be subject to this regulation that 
determines, because of its size, it is likely to bear a 
disproportionate adverse economic impact should notify the Commission 
of this opinion in a comment that indicates--
    (1) The applicant's size and how the proposed regulation would 
impose a significant economic burden on the applicant as compared to 
the economic burden on a larger applicant;
    (2) How the proposed regulations could be modified to take into 
account the applicant's differing needs or capabilities;
    (3) The benefits that would accrue or the detriments that would be 
avoided if the proposed regulations were modified as suggested by the 
applicant;
    (4) How the proposed regulation, as modified, would more closely 
equalize the impact of NRC regulations or create more equal access to 
the benefits of Federal programs as opposed to providing special 
advantages to any individual or group; and
    (5) How the proposed regulation, as modified, would still 
adequately meet the NRC's obligations under NEPA.

VII. Regulatory Analysis

    The NRC has prepared a draft regulatory analysis on this proposed 
regulation. The analysis examines the costs and benefits of the 
alternatives considered by the NRC. The NRC requests public comment on 
the draft regulatory analysis. The regulatory analysis is available as 
indicated in the ``Availability of Documents'' section of this 
document. Comments on the draft analysis may be submitted to the NRC as 
indicated under the ADDRESSES caption of this document.

VIII. Backfitting and Issue Finality

    The proposed rule would codify in 10 CFR part 51 certain 
environmental issues identified in the NR GEIS. The proposed rule also 
revises 10 CFR part 51 to allow an applicant for a new nuclear reactor 
construction permit or operating license under 10 CFR part 50, or a new 
nuclear reactor early site permit or combined license under 10 CFR part 
52, to use the NR GEIS in preparing its environmental report. The 
proposed rule would require the NRC staff to prepare a project-specific 
draft SEIS and final SEIS for each application that references the NR 
GEIS. The NRC has determined that the backfitting rule in Sec.  50.109, 
``Backfitting,'' and the issue finality provisions in 10 CFR part 52 do 
not apply to this proposed rule because this amendment does not involve 
any provision that would either constitute backfitting as that term is 
defined in 10 CFR chapter I or affect the issue finality of any 
approval issued under 10 CFR part 52.
    The proposed rule would not constitute backfitting for applicants 
for construction permits or operating licenses under 10 CFR part 50 and 
would not affect the issue finality of applicants for early site 
permits or combined licenses under 10 CFR part 52. These applicants are 
not, with certain exceptions not applicable here, within the scope of 
the backfitting or issue finality provisions. The backfitting and issue 
finality regulations include language delineating when the backfitting 
and issue finality provisions begin; in general, they begin after the 
issuance of a license, permit, or other approval (e.g., Sec. Sec.  
50.109(a)(1)(iii) and 52.98(a)). Furthermore, neither the backfitting 
provisions nor the issue finality provisions, with certain exceptions 
not applicable here, are intended to apply to NRC actions that 
substantially change the expectations of current and future applicants. 
Applicants cannot reasonably expect that future requirements will not 
change.
    The exceptions to the general principle are applicable when an 
applicant references a 10 CFR part 52 approval (e.g., an early site 
permit or design certification rule) with specified issue finality 
provisions or a construction permit under 10 CFR part 50. However, this 
proposed rule would have no effect on a construction permit held by an 
applicant for a 10 CFR part

[[Page 80810]]

50 operating license or an early site permit referenced by an applicant 
for a 10 CFR part 52 combined license. Therefore, for purposes of this 
proposed rule, the exceptions to the general principle do not apply.

IX. Cumulative Effects of Regulation

    The NRC is following its cumulative effects of regulation (CER) 
process by engaging with external stakeholders throughout the 
rulemaking and related regulatory activities. Public involvement has 
included (1) the publication of a notice announcing an exploratory 
process and opportunity for comment to determine the possible utility 
of developing an advanced nuclear reactor GEIS on November 15, 2019 (84 
FR 62559); (2) public meetings on November 15 and November 20, 2019, 
and a workshop on January 8, 2020, to gather information for the 
exploratory process; (3) the publication of a notice of intent to 
conduct scoping and prepare an advanced nuclear reactor GEIS on April 
30, 2020 (85 FR 24040); (4) a public meeting on May 28, 2020, to 
receive comments on the scope of the GEIS; and (5) public meetings on 
October 1, 2020 and April 15, 2021, to share information about the 
NRC's progress on the development of the GEIS.
    The NRC is issuing draft guidance along with this proposed rule to 
support more informed external stakeholder understanding and feedback. 
The draft guidance is available as indicated in the ``Availability of 
Documents'' section of this document. Further, the NRC will continue to 
hold public meetings throughout the rulemaking process.
    In addition to the questions on the implementation of this proposed 
rule presented in the ``Specific Requests for Comments'' section of 
this document, the NRC is requesting CER feedback on the following 
questions:
    1. In light of any current or projected CER challenges, does the 
proposed rule's effective date, compliance date, or submittal date(s) 
provide sufficient time to implement the new proposed requirements, 
including changes to programs, procedures, and the facility? Provide a 
rationale for your answer.
    2. If CER challenges currently exist or are expected, what should 
be done to address them? For example, if more time is required for 
implementation of the new requirements, what period of time is 
sufficient?
    3. Do other (NRC or other agency) regulatory actions (e.g., orders, 
generic communications, license amendment requests, inspection findings 
of a generic nature) influence the implementation of this proposed 
rule's requirements? Provide a rationale for your answer.
    4. Are there unintended consequences? Does the proposed rule create 
conditions that would be contrary to this proposed rule's purpose and 
objectives? If so, what are the unintended consequences, and how should 
they be addressed?
    5. Please comment on the NRC's cost and benefit estimates in the 
draft regulatory analysis that supports the proposed rule. The draft 
regulatory analysis is available as indicated in the ``Availability of 
Documents'' section of this document.

X. Plain Writing

    The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal 
agencies to write documents in a clear, concise, and well-organized 
manner. The NRC has written this document to be consistent with the 
Plain Writing Act as well as the Presidential Memorandum, ``Plain 
Language in Government Writing,'' published June 10, 1998 (63 FR 
31885). The NRC requests comment on this document with respect to the 
clarity and effectiveness of the language used.

XI. National Environmental Policy Act

    The NRC has determined that this proposed rule is the type of 
action described in Sec.  51.22(c)(3), an NRC categorical exclusion. 
Therefore, neither an environmental impact statement nor environmental 
assessment has been prepared for this proposed rule. This action is 
procedural in nature in that it pertains to the type of environmental 
information to be reviewed.

XII. Paperwork Reduction Act

    This proposed rule contains new or amended collections of 
information subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 
3501 et seq.). This proposed rule has been submitted to the Office of 
Management and Budget for review and approval of the information 
collections.
    Type of submission: Revision.
    The title of the information collection: 10 CFR part 51, Generic 
Environmental Impact Statement for Licensing of New Nuclear Reactors.
    The form number if applicable: Not applicable.
    How often the collection is required or requested: On occasion.
    Who will be required or asked to respond: Applicants for new 
nuclear reactors.
    An estimate of the number of annual responses: 6.
    The estimated number of annual respondents: 6.
    An estimate of the total number of hours needed annually to comply 
with the information collection requirement or request: A burden 
reduction of 39,288 hours.
    Abstract: The NRC is proposing to amend the regulations that govern 
the NRC's environmental reviews of new nuclear reactor applications 
under NEPA. The NRC's regulations in Sec.  51.45, ``Environmental 
report,'' require each applicant to prepare and submit an environmental 
report which includes, among other things, a description of the 
proposed action, a statement of its purposes, a description of the 
environment affected, and a discussion of the environmental impacts of 
the proposed action and alternatives. The rulemaking would codify the 
generic findings of NUREG-2249, ``Generic Environmental Impact 
Statement for Licensing of New Nuclear Reactors'' (NR GEIS), which 
presents impact analyses for the environmental issues common to many 
new nuclear reactors that can be addressed generically, thereby 
eliminating the need to repeatedly reproduce the same analyses each 
time a licensing application is submitted. The proposed rule would 
reduce burden on an applicant because they would not be required to 
assess the environmental impacts of NR GEIS Category 1 issues if: (1) 
the applicant has demonstrated that it has met the bounding values and 
assumption of each PPE and SPE parameter relevant to that Category 1 
issue, and (2) the applicant has not identified any new and significant 
information that would change a conclusion related to a Category 1 
issue in the NR GEIS. If a value or assumption is not met, then the 
applicant may be able to limit its analysis to just the impact of not 
meeting the value or assumption. Similarly, if the applicant identifies 
new and significant information that would change a conclusion in the 
NR GEIS, then the applicant may be able to limit its analysis to just 
the impact of the new and significant information. To comply with NEPA, 
the NRC uses the information in the environmental report along other 
information to conduct an independent environmental evaluation.
    The NRC is seeking public comment on the potential impact of the 
information collection contained in this proposed rule and on the 
following issues:
    1. Is the proposed information collection necessary for the proper 
performance of the functions of the NRC, including whether the 
information will have practical utility? Please explain your response.
    2. Is the estimate of the burden of the proposed information 
collection accurate? Please explain your response.

[[Page 80811]]

    3. Is there a way to enhance the quality, utility, and clarity of 
the information to be collected? Please explain your response.
    4. How can the burden of the proposed information collection on 
respondents be minimized, including the use of automated collection 
techniques or other forms of information technology?
    A copy of the Office of Management and Budget (OMB) clearance 
package and proposed rule are available in ADAMS as indicated in the 
``Availability of Documents'' section of this document or may be viewed 
free of charge by contacting the NRC's Public Document Room reference 
staff at 1-800-397-4209, at 301-415-4737, or by email to 
[email protected]. You may obtain information and comment 
submissions related to the OMB clearance package by searching on 
https://www.regulations.gov under Docket ID NRC-2020-0101.
    You may submit comments on any aspect of these proposed information 
collections, including suggestions for reducing the burden and on the 
above issues, by the following methods:
     Federal rulemaking website: Go to https://www.regulations.gov and search for Docket ID NRC-2020-0101.
     Mail comments to: FOIA, Library, and Information 
Collections Branch, Office of the Chief Information Officer, Mail Stop: 
T6-A10M, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001 
or by email to [email protected] or to the OMB reviewer at: 
OMB Office of Information and Regulatory Affairs (3150-0021), Attn: 
Desk Officer for the Nuclear Regulatory Commission, 725 17th Street NW, 
Washington, DC 20503.
    Submit comments by November 4, 2024. Comments received after this 
date will be considered if it is practical to do so, but the NRC is 
able to ensure consideration only for comments received on or before 
this date.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, a collection of information unless the document requesting 
or requiring the collection displays a currently valid OMB control 
number.

XIII. Voluntary Consensus Standards

    The National Technology Transfer and Advancement Act of 1995, 
Public Law 104-113, requires that Federal agencies use technical 
standards that are developed or adopted by voluntary consensus 
standards bodies unless the use of such a standard is inconsistent with 
applicable law or otherwise impractical. In this proposed rule, the NRC 
will amend various provisions of 10 CFR part 51. This action does not 
constitute the establishment of a standard that contains generally 
applicable requirements.

XIV. Availability of Guidance

    The NRC is issuing for comment two draft guidance documents, DG-
4032, ``Preparation of Environmental Reports for Nuclear Power 
Stations,'' and draft interim staff guidance (ISG) document COL-ISG-
030, ``Environmental Considerations Associated with New Nuclear Reactor 
Applications that Reference the Generic Environmental Impact Statement 
(NUREG-2249)--Interim Staff Guidance,'' to support the implementation 
of the requirements in this proposed rulemaking. The guidance documents 
are available as indicated in the ``Availability of Documents'' section 
of this document. You may submit comments on the draft regulatory 
guidance by the methods provided in the ADDRESSES section of this 
document.
    The DG-4032 has been prepared as a revision to RG 4.2, 
``Preparation of Environmental Reports for Nuclear Power Stations.'' 
The revision updates and re-titles Appendix C to the regulatory guide, 
which previously provided guidance specifically for small modular 
reactors and non-LWRs and makes conforming changes to the body of the 
regulatory guide. The revisions provide supplemental guidance for 
applicants to establish a uniform format and content acceptable to the 
NRC staff for structuring and presenting the environmental information 
to be compiled and submitted by an applicant for a new nuclear reactor 
permit or license that will rely on any of the findings in the NR GEIS. 
More specifically, the draft regulatory guide describes the content of 
environmental information to be included in an application for a permit 
or license for a new nuclear reactor, including the process for 
confirming the applicability of Category 1 issues, and criteria to 
address appropriate Category 1 and Category 2 issues, as specified in 
the proposed amendments to 10 CFR part 51. To assist the public in 
providing comments on DG-4032, the NRC has provided a redline/strikeout 
version that highlights substantial changes which can be accessed in 
ADAMS at Accession No. ML24176A229.
    In addition, the NRC is seeking comment on two draft documents 
referenced in DG-4032, the ``Energy and System Design Mitigation 
Alternatives White Paper'' (``White Paper'') and ``Recommendations for 
an Applicant to Calculate Activity Data for Greenhouse Gases 
Estimates'' (``GHG Estimates''). The draft White Paper describes the 
potential environmental impacts of various energy alternatives to the 
construction and operation of a new nuclear reactor, including energy 
alternatives both requiring and not requiring new generation capacity. 
The draft GHG Estimates document provides guidance to nuclear reactor 
applicants on estimating greenhouse gas emissions. The applicant could 
then rely upon the information provided in both the White Paper and the 
GHG Estimates documents, as appropriate, in preparing its environmental 
report that is submitted with its application. The draft White Paper 
and the draft GHG Estimates document can be accessed in ADAMS at 
Accession Nos. ML21225A754 and ML21225A768, respectively.
    The draft COL-ISG-030 supplements NUREG-1555, ``Environmental 
Standard Review Plans,'' and will be incorporated into a future update 
to the NUREG. The ISG provides guidance for the NRC staff when 
performing a 10 CFR part 51 environmental review of an application for 
a permit or license for a new nuclear reactor that relies on any of the 
findings in the NR GEIS. The plan parallels the revisions to RG 4.2. 
The primary purpose of the ISG is to ensure that these reviews are 
focused on the significant environmental concerns associated with new 
nuclear reactor permitting or licensing as described in 10 CFR part 51. 
Specifically, it provides guidance to the NRC staff about environmental 
issues that should be reviewed and provides acceptance criteria to help 
the reviewer evaluate the information submitted as part of the permit 
or license application. It is also the intent of this review plan to 
make information about the regulatory process available and to improve 
communication between the NRC, interested members of the public, and 
the nuclear industry, thereby increasing understanding of the review 
process.

XV. Public Meetings

    The NRC will conduct three public meetings on the proposed rule for 
the purpose of explaining the changes and answering questions from the 
attendees to facilitate the development of public comments.
    An in-person public meeting will be held on November 7, 2024, at 
NRC headquarters in Rockville, MD between 1 p.m. and 4 p.m. eastern 
time.
    In addition, the NRC will hold two virtual public meetings as 
online webinars. The online webinars will be conducted on November 13, 
2024, between 1 p.m. and 4 p.m. eastern time

[[Page 80812]]

and November 14, 2024, between 6 p.m. and 9 p.m. eastern time.
    Persons interested in attending the meetings should monitor the 
NRC's Public Meeting Schedule website at https://www.nrc.gov/pmns/mtg 
for additional information and agenda for the meetings. Please contact 
Stacey Imboden, 301-415-2462, [email protected], no later than 
October 31, 2024, if accommodations or special equipment is needed to 
attend or to provide comments, so that the NRC can determine whether 
the request can be accommodated.

2. In Sec.  51.50, amend paragraph (a) by adding a new second sentence, 
and add paragraph (d) to read as follows:

Sec.  51.50  Environmental report--construction permit, early site 
permit, or combined license stage.

    (a) * * * For non-light-water reactors as defined in Sec.  50.2, 
the environmental report shall contain the basis for evaluating the 
contribution of the environmental effects of fuel cycle activities for 
the nuclear reactor. * * *
* * * * *
    (d) Application for a construction permit, early site permit, or 
combined license for a nuclear reactor. If an application is for a 
construction permit, an early site permit, or a combined license that 
does not reference an early site permit for a nuclear reactor, as 
defined in 10 CFR 50.2, and further, if the applicant chooses to rely 
upon the findings of one or more of the issues identified as Category 1 
issues in appendix C to subpart A of this part, then, in addition to 
the information and analyses required in paragraph (a), (b), or (c) of 
this section, as appropriate, the applicant's environmental report will 
be subject to the following conditions and considerations:
    (1) The environmental report must contain information to 
demonstrate that the values and assumptions in appendix C to subpart A 
of this part are met, and no new and significant information is 
identified in accordance with paragraph (d)(5) of this section, for 
each Category 1 issue for which the applicant relies on the finding for 
that issue.
    (2) The environmental report is not required to contain analyses of 
the environmental impacts of any issue identified as a Category 1 issue 
in appendix C to subpart A of this part, provided that the 
environmental report contains the information specified in paragraph 
(d)(1) of this section.
    (3) The environmental report must contain analyses of the 
environmental impacts of the proposed action, including the 
construction, operation, and decommissioning of the proposed nuclear 
reactor, for:
    (i) Any Category 1 issue for which the values and assumptions are 
not met or for which new and significant information is identified in 
accordance with paragraph (d)(5) of this section; and
    (ii) Each issue identified as a Category 2 issue in appendix C to 
subpart A of this part.
    (4) The environmental report must contain a consideration of 
alternatives for reducing adverse environmental impacts, as required by 
Sec.  51.45(c), for all issues identified as Category 1 issues in 
appendix C to subpart A of this part for which the environmental report 
does not contain the information specified in paragraph (d)(1) of this 
section, and for all issues identified as Category 2 issues in appendix 
C to subpart A of this part. No such consideration is required for 
Category 1 issues in appendix C to subpart A of this part that meet the 
applicable values and assumptions as specified in paragraph (d)(1) of 
this section.
    (5) The environmental report must contain any new and significant 
information of which the applicant is aware regarding the environmental 
impacts for all issues identified as Category 1 issues in appendix C to 
subpart A of this part for which the applicant relies on the findings 
for those issues.
    (6) The environmental report must contain a description of the 
process used to identify new and significant information regarding the

4. In Sec.  51.75, add paragraph (d) to read as follows:

Sec.  51.75   Draft environmental impact statement--construction 
permit, early site permit, or combined license.

* * * * *
    (d) Construction permit, early site permit, or combined license for 
a nuclear reactor. If a draft environmental impact statement is being 
prepared in accordance with paragraph (a), (b), or (c) of this section, 
and if applicant's environmental report relied upon the findings of one 
or more of the issues identified as Category 1 issues in appendix C to 
subpart A of this part, the draft environmental impact statement must 
be prepared as a supplement to NUREG-2249, ``Generic Environmental 
Impact Statement for Licensing of New Nuclear Reactors'' (September 
2024), which is available in the NRC's Public Document Room, 11555 
Rockville Pike, Rockville, Maryland 20852. In addition, the NRC staff 
must comply with 40 CFR 1506.6(b)(3) in conducting the additional 
scoping process as required by Sec.  51.71(a). The draft supplemental 
environmental impact statement will incorporate the conclusions in 
NUREG-2249 for issues identified as Category 1 for which the applicant 
has demonstrated that the applicable values and assumptions have been 
met and for which neither the applicant nor the NRC identified any new 
and significant information. The draft supplemental environmental 
impact statement must contain an analysis for those issues identified 
as Category 1 for which the applicant could not demonstrate that the 
applicable values and assumptions were met or for which any new and 
significant information was identified by the applicant or the NRC, and 
for those issues identified as Category 2.

combined license that does not reference an early site permit for a 
nuclear reactor, as defined in 10 CFR 50.2, and for which the NRC staff 
relied on any of the findings in appendix C to subpart A of this part 
in preparing a draft supplemental environmental impact statement in 
accordance with Sec.  51.75(d), the NRC shall prepare a final 
supplemental environmental impact statement, which is a supplement to 
the Commission's NUREG-2249, ``Generic Environmental Impact Statement 
for Licensing of New Nuclear Reactors'' (September 2024), and available 
in the NRC's Public Document Room, 11555 Rockville Pike, Rockville, 
Maryland 20852.
    (b) The final supplemental environmental impact statement required 
by paragraph (a) of this section must contain the NRC staff's 
recommendation regarding the environmental acceptability of approving 
the construction permit, the early site permit, or the combined 
license. In order to make recommendations and reach a final decision on 
the proposed action, the NRC staff, adjudicatory officers, and 
Commission shall integrate:
    (1) The conclusions in NUREG-2249 for issues designated as Category 
1 for which the applicant has demonstrated that the applicable values 
and assumptions have been met and for which neither the applicant nor 
the NRC staff identified any new and significant information with
    (2) Information developed for those Category 1 issues for which the 
applicant could not demonstrate that the applicable values and 
assumptions were met and those Category 2 issues applicable to the 
plant under Sec.  51.50(d) and any new and significant information.
    (c) The final supplemental environmental impact statement required 
by paragraph (a) of this section shall address those issues as required 
by Sec.  51.91 and shall be distributed in accordance with Sec.  51.93.
    (d) In connection with a combined license that references an early 
site permit for which the NRC staff relied on any of the findings in 
appendix C to subpart A of this part in preparing the supplemental 
environmental impact statement for that early site permit, the NRC 
shall prepare a supplement to that final supplemental environmental 
impact statement. The supplement must meet the requirements of Sec.  
51.92(e) and shall be considered a supplement to NUREG-2249.
    (e) In connection with a combined license that references an early 
site permit for which the NRC staff relied on any of the findings in 
appendix C to subpart A of this part in preparing the draft 
supplemental environmental impact statement, the NRC staff shall 
prepare a supplement to the early site permit environmental impact 
statement. The supplement must be prepared in accordance with Sec.  
51.92(e) and shall be considered a supplement to NUREG-2249.
    (f) In connection with the issuance of an operating license for 
which the NRC staff relied on any of the findings in appendix C to 
subpart A of this part in preparing the supplemental environmental 
impact statement for the construction permit for that nuclear reactor, 
the NRC shall prepare a supplement to the final supplemental 
environmental impact statement. The supplement must meet the 
requirements of Sec.  51.95(b) and shall be considered a supplement to 
NUREG-2249.

6. Add appendix C to subpart A of part 51 to read as follows:

Appendix C to Subpart A of Part 51--Environmental Effect of Issuing a 
Permit or License for a New Nuclear Reactor

    The Commission has assessed the environmental impacts associated 
with authorizing the construction, operation, and decommissioning of 
a nuclear reactor. Table C-1 summarizes the Commission's generic 
findings on the scope and magnitude of environmental impacts of such 
an authorization as required by section 102(2) of the National 
Environmental Policy Act of 1969, as amended. Table C-1 presents the 
results of the generic analysis of those environmental impacts 
associated with building,\1\ operating, and decommissioning a 
nuclear reactor that the staff has designated as Category 1, as well 
as listing the issues that could not be resolved generically, 
designated as Category 2. The use of this table by applicants will 
be in accordance with Sec.  51.50(d), and the use by the staff will 
be in accordance with Sec. Sec.  51.75(d) and 51.96. On a 10-year 
cycle, the Commission intends to review the material in this 
appendix and update it if necessary. A scoping notice must be 
published in the Federal Register indicating the results of the 
NRC's review and inviting public comments and proposals for other 
areas that should be updated.

\1\ Data supporting this table are contained in NUREG-2249, ``Generic Environmental Impact Statement for
  Licensing of New Nuclear Reactors'' (September 2024).
\2\ The categories are defined as follows:
Category 1 issues--environmental issues for which the NRC has been able to make a generic finding of SMALL
  adverse environmental impacts, or beneficial impacts, provided that the applicant's proposed reactor facility
  and site meet or are bounded by relevant values and assumptions in the PPE and SPE that support the generic
  finding for that Category issue.

[[Page 80827]]

 
Category 2 issues--Environmental issues for which a generic finding regarding the environmental impacts cannot
  be reached because the issue requires the consideration of project-specific information that can only be
  evaluated once the proposed site is identified. The impact significance (i.e., SMALL, MODERATE, or LARGE) for
  these issues will be determined in a project-specific evaluation.
N/A--Issues related to exposure to electromagnetic fields (EMFs) for which there is no national scientific
  agreement regarding adverse health effects.
\3\ A finding of SMALL impacts means that environmental effects are not detectable or are so minor that they
  will neither destabilize nor noticeably alter any important attribute of the resource. For the purposes of
  assessing radiological impacts, the Commission has concluded that those impacts that do not exceed permissible
  levels in the Commission's regulations are considered SMALL as the term is used in this table. For issues
  where probability is a key consideration (i.e., accident consequences), probability was a factor in
  determining significance.
\4\ Because the Category 2 issues require a project-specific review, there are no associated values and
  assumptions of the plant parameter envelope and site parameter envelope. A brief summary explanation for the
  designation of the Category 2 issues is provided in lieu of values and assumptions.

    Dated: September 25, 2024.

Secretary of the Commission.
