SUPPLEMENTARY INFORMATION:

I. Background

In accordance with section 51.118 of title 10 of the Code of Federal Regulations, “Final environmental impact statement—notice of availability,” the NRC is making available to the public NUREG-1437, Supplement 10, Second Renewal, Supplement 1 regarding the subsequent renewal of Renewed Facility Operating License Nos. DPR-44 and DPR-56 for an additional 20 years for Peach Bottom. A notice of availability of the draft supplement, which updated the 2020 final SEIS, was published in the Federal Register on May 30, 2025 (90 FR 23075). The U.S. Environmental Protection Agency issued its notice of availability of the draft supplement on May 30, 2025 (90 FR 23050). The public comment period on the draft supplement ended on July 14, 2025, and the comments received on the draft supplement are addressed in the final supplement.

II. Discussion

The draft supplement, which updated the 2020 final SEIS, was issued for public comment on May 30, 2025. The final supplement (NUREG-1437, Supplement 10, Second Renewal, Supplement 1) addresses the comments received on the draft supplement. As discussed in Chapter 4 of the final supplement, the NRC staff has determined that the adverse environmental impacts of subsequent license renewal for Peach Bottom ( i.e., the continued operation of Peach Bottom for a period of 20 years beyond the expiration dates of the current licenses) are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable. This recommendation is based on: (1) information in the environmental report, as supplemented, and other documents submitted by Constellation Energy Generation, LLC; (2) the NRC staff's consultation with Federal, State, Tribal, and local governmental agencies; (3) the NRC staff's independent environmental review; and (4) the NRC staff's consideration of public comments received during the scoping process and on the draft of the 2020 final SEIS and the draft supplement.

Dated: August 21, 2025.
