SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is considering the approval of the initial and updated DFPs 
submitted by the STP 1 and 2 ISFSI licensee, and the NRC staff has 
prepared a final EA and FONSI determination for the initial and updated 
STP 1 and 2 ISFSI DFPs in accordance with the NRC regulations in part 
51 of title 10 of the Code of Federal Regulations (10 CFR), 
``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions,'' which implement the National 
Environmental Policy Act of 1969, as amended (42 U.S.C. 4321 et seq.).
    The NRC requires its licensees to plan for the eventual 
decommissioning of their licensed facilities prior to license 
termination. On June 17, 2011, the NRC published a final rule in the 
Federal Register amending its decommissioning planning regulations (76 
FR 35512). The final rule amended the NRC regulation, 10 CFR 72.30, 
``Financial assurance and recordkeeping for decommissioning,'' which 
concerns financial assurance and decommissioning for ISFSIs. This 
regulation requires each holder of, or applicant for, a license under 
10 CFR part 72 to submit a DFP for the NRC's review and approval. The 
purpose of the DFP is to demonstrate the licensee's financial 
assurance, i.e., that funds will be available to decommission the 
ISFSI. The NRC staff will later publish its financial analyses of the 
DFP submittals which will be available for public inspection in ADAMS.

II. Discussion

    The table in this notice includes the plant name, docket number, 
licensee, and ADAMS accession number for the final EA and FONSI 
determination for the STP 1 and 2 ISFSI. The table also includes the 
ADAMS accession numbers for other relevant documents, including the 
initial and updated DFP submittals. For further details with respect to 
these actions, see the NRC staff's final EA and FONSI determinations 
which are available for public inspection in ADAMS and at https://www.regulations.gov under Docket ID NRC-2025-1535. For additional 
direction on accessing information related to this document, see the

Docket No..............................  72-1041.
Licensee...............................  South Texas Project Nuclear Operating Company (STPNOC).
Proposed Action........................  The NRC's review and approval of STPNOC's initial and updated
                                          decommissioning funding plans (DFPs) submitted in accordance with 10
                                          CFR 72.30(b) and (c), respectively.

Environmental Impact of Proposed Action  The NRC staff has determined that the proposed action, the review and
                                          approval of STPNOC's initial and updated DFPs, submitted in accordance
                                          with 10 CFR 72.30(b) and (c), will not authorize changes to licensed
                                          operations or maintenance activities, or result in changes in the
                                          types, characteristics, or quantities of radiological or non-
                                          radiological effluents released into the environment from the
                                          independent spent fuel storage installation (ISFSI), or result in the
                                          creation of solid waste. Moreover, the approval of the initial and
                                          updated DFPs will not authorize any construction activity, facility
                                          modification, or other land-disturbing activity. The NRC staff has
                                          concluded that the proposed action is a procedural and administrative
                                          action that will not have a significant impact on the environment.
Finding of No Significant Impact.......  The proposed action does not require changes to the ISFSI's licensed
                                          routine operations, maintenance activities, or monitoring programs,
                                          nor does it require new construction or land-disturbing activities.
                                          The scope of the proposed action concerns only the NRC's review and
                                          approval of STPNOC's initial and updated DFPs. The scope of the
                                          proposed action does not include, and will not result in, the review
                                          and approval of decontamination or decommissioning activities or
                                          license termination for the ISFSI or for other parts of STP 1 and 2.
                                          Therefore, the NRC staff determined that approval of the initial and
                                          updated DFPs for the STP 1 and 2 ISFSI will not significantly affect
                                          the quality of the human environment, and accordingly, the staff has
                                          concluded that a FONSI is appropriate. The NRC staff further finds
                                          that preparation of an environmental impact statement is not required.
