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 62. A Notice of Availability of the draft of NUREG-1437, 
Supplement 62 was published in the Federal Register on November 1, 2024 
(89 FR 87433). The U.S. Environmental Protection Agency issued its 
Notice of Availability on November 1, 2024 (89 FR 87366). The public 
comment period on the draft of NUREG-1437, Supplement 62 ended on 
December 16, 2024, and the comments received are addressed in NUREG-
1437, Supplement 62.

II. Discussion

    The draft of NUREG-1437, Supplement 62 was issued for public 
comment on November 1, 2024. NUREG-1437, Supplement 62 addresses the 
comments received. As discussed in Chapter 4 of NUREG-1437, Supplement 
62, the NRC staff has determined that the adverse environmental impacts 
of license renewal for Diablo Canyon (i.e., the continued operation of 
Diablo Canyon for a period of 20 years beyond the expiration dates of 
the current operating licenses) are not so great that preserving the 
option of license renewal for energy-planning decision-makers would be 
unreasonable. This recommendation is based on: (1) information in the 
environmental report, as supplemented, and other documents submitted by 
Pacific Gas and Electric Company; (2) 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 NUREG-1437, Supplement 62.

    Dated: June 24, 2025.

    For the Nuclear Regulatory Commission.
