In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on October 14, 2025. The NRC received and docketed one comment on the companion proposed rule (90 FR 35640; July 29, 2025). An electronic copy of the comment can be obtained from the Federal Rulemaking website at <E T="03">https://www.regulations.gov</E> under Docket ID NRC-2025-0070 and is also available in ADAMS under Accession No. ML25241A013. The NRC evaluated the comment against the criteria described in the direct final rule and determined that the comment was not significant and adverse. Specifically, the comment was outside the scope of this rulemaking. The comment did not raise a relevant issue that was not previously addressed or considered by the NRC. It did not cause the NRC to either reevaluate its position or conduct additional analysis. It did not propose a change or an addition to the rule or cause the NRC to make a change to the rule, the certificate of compliance, or the accompanying technical specifications. Therefore, this direct final rule will become effective as scheduled. <SIG> <DATED>Dated: September 4, 2025.</DATED> For the Nuclear Regulatory Commission. <NAME>Araceli Billoch Colon,</NAME> Chief, Regulatory Analysis and Rulemaking Support Branch, Division of Rulemaking, Environmental, and Financial Support.
