SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is considering the approval of the initial and updated DFPs
submitted by the TMI-1 ISFSI licensee, and the NRC staff has prepared a
final EA and FONSI determination for the initial and updated TMI-1
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
[[Page 42037]]
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 TMI-1 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-2025-1006. For additional
direction on accessing information related to this document, see the
ADDRESSES section of this document.
Finding of No Significant Impact
------------------------------------------------------------------------
Three Mile Island Nuclear Station,
Facility Unit 1 (TMI-1)
------------------------------------------------------------------------
Docket No....................... 72-77.
Licensees....................... Exelon Generation Company, LLC (EGC)--
initial submittal.
Constellation Energy Generation, LLC
(CEG)--updated submittal.
Proposed Action................. The NRC's review and approval of EGC's
initial and CEG's updated
decommissioning funding plans (DFPs)
submitted in accordance with 10 CFR
72.30(c).
Environmental Impact of Proposed The NRC staff has determined that the
Action. proposed action, the review and
approval of EGC's initial and CEG's
updated DFPs, submitted in accordance
with 10 CFR 72.30(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
EGC's initial and CEG's 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 TMI-
1. Therefore, the NRC staff
determined that approval of the
initial and updated DFPs for the TMI-
1 ISFSI will not significantly affect
the quality of the human environment,
and accordingly, the staff has
concluded that a Finding of No
Significant Impact (FONSI) is
appropriate. The NRC staff further
finds that preparation of an
environmental impact statement is not
required.
