Summary

The U.S. Nuclear Regulatory Commission (NRC) is confirming the effective date of January 8, 2026, for the direct final rule that was published in the Federal Register on December 3, 2025, except for one provision that is being withdrawn. This direct final rule amended the NRC's regulations to insert a conditional sunset date into certain regulations in response to Executive Order 14270, ``Zero-Based Regulatory Budgeting to Unleash American Energy.'' The NRC is withdrawing an amendment that would have established a conditional sunset date to the NRC's provisions for aircraft impact assessment.

Partial Withdrawal: As of January 8, 2026, amendatory instruction 42 published on December 3, 2025, at 90 FR 55621, is withdrawn. Effective Date: The effective date of January 8, 2026, for the direct final rule published December 3, 2025 (90 FR 55621), except for one amendment as described in this document, is confirmed.

Supplementary Information

On December 3, 2025 (90 FR 55621), the NRC published a direct final rule amending its regulations to insert a conditional sunset date into certain regulations in response to Executive Order 14270, ``Zero-Based Regulatory Budgeting to Unleash American Energy.'' In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on January 8, 2026. The NRC received and docketed eleven comments on the companion proposed rule (90 FR 55699; December 3, 2025). An electronic copy of the comments can be obtained from the Federal Rulemaking website at https://www.regulations.gov under Docket ID NRC-2025-0479. The NRC evaluated the comments against the criteria described in the direct final rule and determined that some of the comments were significant and adverse. Specifically, certain comments concerning 10 CFR 50.150, ``Aircraft impact assessment,'' were significant and adverse. For this reason, the NRC is removing instruction 42 to amend 10 CFR 50.150 from the direct final rule. The NRC will address comments on that proposed amendment in a final rule to be issued at a later time. Removing the change to 10 CFR 50.150 would not have any impact on the other changes in the direct final rule. No other comments on the rule raised a relevant issue that was not previously addressed or considered by the NRC. Therefore, the direct final rule, minus the amendment to 10 CFR 50.150, will become effective as scheduled. Dated: January 6, 2026. For the Nuclear Regulatory Commission.
