Executive Orders XI. Congressional Review Act XII. Availability of Documents I. Executive Order 14300: Ordering the Reform of the Nuclear Regulatory Commission On May 23, 2025, the President signed Executive Order (E.O.) 14300, “Ordering the Reform of the Nuclear Regulatory Commission.” Section 5, “Reforming and Modernizing the NRC's Regulations,” requires the NRC to undertake a review and wholesale revision of its regulations and guidance documents as guided by the policies set forth in section 2 of the E.O. This rulemaking addresses section 5(j), which requires the NRC to “Streamline the public hearings process,” and also supports meeting the objectives of sections 5(a), 5(d), and 5(e) of E.O. 14300, as discussed below. II. Background Section 189 of the Atomic Energy Act of 1954, as amended

(AEA)requires mandatory (uncontested) hearings for applications under section 103 or 104b of the AEA for a construction permit for a facility, and on any application under section 104c for a construction permit for a testing facility. Over the last two decades the Commission has revisited its process for conducting these mandatory hearings several times. In 2007, as part of a major revision to 10 CFR part 52, “Licenses, Certifications, And Approvals for Nuclear Power Plants,” the Commission revised § 2.104 to remove all provisions specifying safety and environmental findings to be made by the presiding officer in hearings (72 FR 49352, 49412, August 28, 2007). This change to the NRC's rules of procedure was based on the Commission's desire to ensure maximum flexibility in the conduct of mandatory reactor licensing hearings and its determination, based on prior experience and consideration of the nature of mandatory hearings under section 189 of the AEA, that such detailed prescription was unnecessary (ADAMS Accession No. ML071010223). No reference was made at that time to §§ 51.105 and 51.107, which contain provisions specifying environmental findings to be made by presiding officers that are similar to those removed from § 2.104. This final rule removes those two provisions from 10 CFR part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions,” and makes conforming changes to remove references to those provisions in other parts of the regulations. In addition, the Commission is revising certain provisions in 10 CFR parts 2, 50, 51, 52, and 53 to clarify that references to hearings in those regulations apply only to contested hearings. III. Discussion In its 1971 decision in *Calvert Cliffs' Coordinating Committee* v. *Atomic Energy Commission,* the U.S. Court of Appeals for the District of Columbia Circuit held that the Atomic Energy Commission (predecessor of the NRC) could not exclude environmental issues from its mandatory reactor licensing hearings that addressed safety and security issues. 449 F.2d 1109, 1117-19 (D.C. Cir. 1971). In response to that decision, the Atomic Energy Commission added to its regulations the provisions containing specific environmental issues to be addressed by the presiding officer, which are now found in §§ 51.105 and 51.107 and were formerly found in § 2.104 (37 FR 15127, 15130-31, 15141-42, July 28, 1972). These provisions call for the presiding officer in mandatory hearings on construction permits, early site permits, and combined licenses to determine whether the requirements in sections 102(2)(A), (C), and

(D)of the National Environmental Policy Act

(NEPA)have been met; to independently consider the final balance among conflicting factors with a view to determining the appropriate action to be taken; to determine whether the permit or license should be issued after weighing costs versus benefits and considering reasonable alternatives; and to determine whether the NRC staff's NEPA review has been adequate. Although the language in the regulations derives from the *Calvert Cliffs* decision, the court did not hold that NEPA required specific findings to be made in a hearing. Rather, the court held that NEPA issues must be considered in the same way that safety and security issues are considered within the process. Therefore, to the extent that NRC regulations required findings on safety and security issues in hearings, they also had to include findings on NEPA issues. At bottom, *Calvert Cliffs* requires only that NEPA issues receive equal treatment to non-environmental issues during the hearing process. Section 189a of the AEA states that a hearing must be held on certain applications but does not prescribe any findings that must be made prior to issuing a license or permit, nor does it prescribe the manner in which a hearing must be held. NEPA and *Calvert Cliffs* likewise do not require particular findings on environmental issues in a hearing unless the NRC is using that hearing to make comparable findings on safety and security issues. Currently, although NRC regulations require the NRC to make certain safety and security findings to issue a license or permit, NRC regulations contain no specific findings that a presiding officer must make in a hearing with respect to those non-environmental issues. Accordingly, because the specific environmental findings delineated in §§ 51.105 and 51.107 are not legally required, the Commission is removing them from the NRC regulations. Removing these findings from the regulations gives the Commission increased flexibility, both now and in the future, in deciding how to efficiently conduct mandatory hearings held pursuant to section 189 of the AEA. In addition to deleting §§ 51.105 and 51.107 from the regulations, the Commission is making conforming changes to other regulations in 10 CFR part 51 to remove references to the deleted sections. The Commission is also making changes to provisions in 10 CFR parts 50, 51, 52, and 53 containing references to hearings to clarify that those provisions are intended to refer only to contested hearings and making changes to 10 CFR part 2 to clarify that the rules governing adjudications do not apply to mandatory reactor licensing hearings under section 189 of the AEA. Similarly, the Commission is removing references in 10 CFR parts 50 and 53 (§§ 50.30(a)(3) and 53.1100(a)(2)) to the Atomic Safety and Licensing Board and the presiding officer requiring service of the application in the mandatory AEA hearing. These provisions have been superseded by the advent of the electronic hearing docket and are being removed as part of this rulemaking because the reference to the mandatory hearing could create confusion in the future. Likewise, references in appendix N of 10 CFR part 52 and in 10 CFR part 53 to the Commission designating a presiding officer to conduct the proceeding on issues relating to the common design are being removed. These provisions are redundant to the provisions in subpart D of 10 CFR part 2 which contain the procedures for the conduct of a proceeding involving an identical design at multiple sites and could create confusion regarding what is needed for a mandatory hearing. Subpart D of 10 CFR part 2 provides the Commission with the flexibility to hold individual or separate proceedings, as appropriate, in any contested hearing. Finally, the Commission is revising certain sections in 10 CFR part 52 (§ 52.24 for early site permits and § 52.97 for combined licenses). These provisions currently state that, after a hearing is conducted and a report is received from the Advisory Committee on Reactor Safeguards, the Commission may issue the permit or license upon making the requisite findings. The references in these regulations to conducting a hearing are being removed to fully sever the historical but unnecessary link between the findings that must be made to support issuance of a license and the conduct of a mandatory hearing pursuant to section 189 of AEA. Because these provisions are procedural rules related to the conduct of hearings, notice and comment is not required under the Administrative Procedure Act, 5 U.S.C. 553(b)(A). IV. Regulatory Flexibility Certification In accordance with the Regulatory Flexibility Act, as amended, 5 U.S.C. 605(b), the NRC certifies that this rule will not have a significant economic impact on a substantial number of small entities. This rule applies in the context of NRC adjudicatory proceedings concerning nuclear reactors. Reactor licensees do not fall within the definition of a small business found in section 3 of the Small Business Act, 15 U.S.C. 632, within the small business standards set forth in 13 CFR part 121, or within the size standards established by the NRC (§ 2.810). V. Regulatory Analysis This final rule removes requirements from the agency's rules of practice for mandatory hearings to further streamline the new reactor licensing process in response to the ADVANCE Act and the May 23, 2025, E.O. 14300, “Ordering the Reform of the Nuclear Regulatory Commission.” This regulatory action removes the findings that a presiding officer must make in a mandatory hearing, which are not required by the AEA or NEPA. This rulemaking does not change the applicant's process in preparing a new license application nor does it change NRC's process for reviewing those applications. This rulemaking has the potential to shorten the time it takes the NRC to review an application by providing additional flexibility in the conduct of the mandatory hearing. These amendments will neither impose new safety requirements nor relax existing ones. The cost savings or benefits 1 of this rule are that it is expected to increase the efficiency with which the NRC conducts mandatory hearings. The elimination of the requirement that the presiding officer in a mandatory hearing make certain findings, which are not required by statute, can not only streamline the hearing process but also mean that the hearing could be conducted earlier in the process such that the mandatory hearing is not on the critical path to license issuance. The NRC expects the costs of implementing this rule to be minimal. The NRC would need to update its mandatory hearing procedures to reflect the additional flexibility. 1 Consistent with the Office of Management and Budget's Circular A-4 (2003), this final rule provides a qualitative analysis in absence of reliable data. Because these benefits outweigh the costs, the NRC expects this final rule to provide a net qualitative benefit without affecting safety. VI. Backfitting and Issue Finality The NRC has determined that the backfit rule and issue finality provisions do not apply to this rule because the amendments do not involve any provisions that would impose backfits as defined in 10 CFR chapter I and are not inconsistent with any applicable issue finality provision in 10 CFR part 52. Therefore, a backfit analysis or issue finality assessment is not required for this rule. VII. 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). VIII. National Environmental Policy Act This rule involves an amendment to hearing procedures (in 10 CFR part 51) with conforming changes to 10 CFR parts 2, 50, 51, 52, and 53, and thus qualifies as an action for which no environmental review is required under the categorical exclusion set forth in 10 CFR 51.22(c)(1). Therefore, neither an environmental impact statement nor an environmental assessment has been prepared for this rulemaking. IX. Paperwork Reduction Act This rule does not contain a collection of information as defined in the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 *et seq.* ) and, therefore, is not subject to the requirements of the Paperwork Reduction Act of 1995. 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. X. Executive Orders Additional information about these statutes and Executive orders can be found at *https://www.nrc.gov/about-nrc/regulatory/rulemaking/procedural-requirements.* Executive Order 12866: Regulatory Planning and Review (as Amended by Executive Order 14215, Ensuring Accountability for All Agencies) The Office of Information and Regulatory Affairs

(OIRA)has determined that this rule is not a significant regulatory action under E.O. 12866. More information can be found in section V, of this document, “Regulatory Analysis.” Executive Order 14154: Unleashing American Energy NRC has examined this final rule and has determined that it is consistent with the policies and directives outlined in E.O. 14154. Executive Order 14192: Unleashing Prosperity Through Deregulation This action is a deregulatory action as defined by E.O. 14192. This final rule is considered an E.O. 14192 deregulatory action. Details on the estimated costs of this final rule can be found in section V, of this document, “Regulatory Analysis.” Executive Order 14270: Zero-Based Regulatory Budgeting To Unleash American Energy Executive Order 14270, “Zero-Based Regulatory Budgeting to Unleash American Energy,” requires the NRC to insert a conditional sunset date into all new or amended NRC regulations provided the regulations are

(1)promulgated under the Atomic Energy Act of 1954, as amended (AEA), the Energy Reorganization Act of 1974, as amended (ERA), and the Nuclear Waste Policy Act of 1982, as amended (NWPA);

(2)not statutorily required; and

(3)not part of the NRC's permitting regime. The NRC determined that the regulatory changes in this rule are for hearing processes that are required by statute and are part of the NRC's regulatory permitting scheme authorized by the AEA, ERA, or NWPA. Therefore, the NRC views this rulemaking to be outside the scope of E.O. 14270 and did not insert conditional sunset dates for the regulatory changes in this final rule. XI. Congressional Review Act This final rule is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has found that it does not meet the criteria at 5 U.S.C. 804(2). XII.
