SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is considering the approval of the decommissioning funding 
plans (DFPs) for the Comanche Peak ISFSI. Luminant Power submitted an 
initial DFP and an updated DFP for NRC review and approval by letters 
dated March 28, 2013 (ADAMS Accession No. ML13136A221), and March 31, 
2015 (ADAMS Accession No. ML15103A281), respectively. The NRC staff has 
prepared a final EA (ADAMS Accession No. ML19120A336) in support of its 
review of Luminant Power's 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.). 
Based on the EA, the NRC staff has determined that approval of the DFPs 
for the Comanche Peak 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 (EIS) is not warranted.

II. Environmental Assessment

Background

    The Comanche Peak ISFSI is located in Glen Rose, Texas. Luminant 
Power is authorized by the NRC, under License No. SFGL-50 to store 
spent nuclear fuel at the Comanche Peak ISFSI.
    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, 
which concerns financial assurance and decommissioning for ISFSIs. This 
regulation now requires each holder of, or applicant for, a license 
under 10 CFR part 72 to submit, for NRC review and approval, a DFP. 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 is reviewing the DFPs submitted by Luminant Power 
on March 28, 2013, and March 31, 2015. Specifically, the NRC must 
determine whether Luminant Power's DFPs contain the information 
required by 10 CFR 72.30(b) and 72.30(c) and whether Luminant Power has 
provided reasonable assurance that funds will be available to 
decommission the ISFSI.

Description of the Proposed Action

    The proposed action is the NRC's review and approval of Luminant 
Power's DFPs submitted in accordance with 10 CFR 72.30(b) and 72.30(c). 
To approve the DFPs, the NRC evaluates whether the decommissioning cost 
estimate (DCE) adequately estimates the cost to conduct the required 
ISFSI decommissioning activities prior to license termination, 
including identification of the volume of onsite subsurface material 
containing residual radioactivity that will require remediation to meet 
the license termination criteria in 10 CFR 20.1402 or 10 CFR 20.1403. 
The NRC also evaluates whether the aggregate dollar amount of Luminant 
Power financial instruments provides adequate financial assurance to 
cover the DCE and that the financial instruments meet the criteria of 
10 CFR 72.30(e). Finally, the NRC evaluates whether the effects of the 
following events have been considered in Luminant Power's submittal: 
(1) Spills of radioactive material producing additional residual 
radioactivity in onsite subsurface material; (2) facility 
modifications; (3) changes in authorized possession limits; and (4) 
actual remediation costs that exceed the previous cost estimate, 
consistent with 10 CFR 72.30(c).
    The proposed action does not require any changes to the ISFSI's 
licensed routine operations, maintenance activities, or monitoring 
programs, nor does it require any new construction or land-disturbing 
activities. The scope of the proposed action concerns only the NRC's 
review and approval of Luminant Power's DFPs. The scope of the proposed 
action does not include, and will not result in, the review and 
approval of any decontamination or decommissioning activity or license 
termination for the ISFSI or any other part of Comanche Peak.

Need for the Proposed Action

    The proposed action provides a means for the NRC to confirm that 
Luminant Power will have sufficient funding to cover the costs of 
decommissioning the ISFSI, including the reduction of the residual 
radioactivity at the ISFSI to the level specified by the applicable NRC 
license termination regulations concerning release of the property (10 
CFR 20.1402 or 10 CFR 20.1403).

Environmental Impacts of the Proposed Action

    The NRC's approval of the DFPs will not change the scope or nature 
of the operation of the ISFSI and will not authorize any changes to 
licensed operations or maintenance activities. The NRC's approval of 
the DFPs will not result in any changes in the types, characteristics, 
or quantities of radiological or non-radiological effluents released 
into the environment from the ISFSI, or result in the creation of any 
solid waste. Moreover, the approval of the DFPs will not authorize any 
construction activity or facility modification. Therefore, the NRC 
staff concludes that the approval of Luminant Power's DFPs is a 
procedural and administrative action that will not result in any 
significant impact to the environment.
    Section 106 of the National Historic Preservation Act of 1966, as 
amended (54 U.S.C. 30618) (NHPA), requires Federal agencies to consider 
the effects of their undertakings on historic properties. In accordance 
with the NHPA implementing regulations at 36 CFR part 800, ``Protection 
of Historic Properties,'' the NRC's approval of Luminant Power's DFPs 
constitutes a Federal undertaking. The NRC, however, has determined 
that the approval of the DFPs is a type of undertaking that does not 
have the potential to cause effects on historic properties, assuming 
such historic properties were present, because the NRC's approval of 
Luminant Power's DFPs will not authorize or result in changes to 
licensed operations or maintenance activities, or changes in the types, 
characteristics, or quantities of radiological or non-radiological 
effluents released into the environment from the ISFSI, or result in 
the creation of any solid waste. Therefore, in accordance with 36 CFR 
800.3(a)(1), no consultation is required under Section 106 of the NHPA.
    Under Section 7 of the Endangered Species Act of 1973 (16 U.S.C. 
1531 et seq.) (ESA), prior to taking a proposed action, a Federal 
agency must determine

[[Page 23089]]

whether (i) endangered and threatened species or their critical 
habitats are known to be in the vicinity of the proposed action and if 
so, whether (ii) the proposed Federal action may affect listed species 
or critical habitats. The NRC has determined that the proposed action 
will have no effect on any listed species or their critical habitats 
because the NRC's approval of Luminant Power's DFPs will not authorize 
or result in changes to licensed operations or maintenance activities, 
or changes in the types, characteristics, or quantities of radiological 
or non-radiological effluents released into the environment from the 
ISFSI, or result in the creation of any solid waste.

Alternative to the Proposed Action

    In addition to the proposed action, the NRC evaluated the no-action 
alternative. The no-action alternative is to deny Luminant Power's 
DFPs. A denial of a DFP that meets the criteria of 10 CFR 72.30(b) or 
72.30(c) does not support the regulatory intent of the 2011 rulemaking. 
As noted in the EA for the 2011 rulemaking (ADAMS Accession No. 
ML090500648), not promulgating the 2011 final rule would have increased 
the likelihood of additional legacy sites. Thus, denying Luminant 
Power's DFPs, which the NRC has found to meet the criteria of 10 CFR 
72.30(b) and 72.30(c), will undermine the licensee's decommissioning 
planning. On this basis, the NRC has concluded that the no-action 
alternative is not a viable alternative.

Agencies and Persons Consulted

    The NRC staff consulted with other agencies and parties regarding 
the environmental impacts of the proposed action. The NRC provided a 
draft of its EA to the Office of the Governor of the State of Texas, 
Office of Budget and Policy (State) by letter dated July 15, 2016 
(ADAMS Accession No. ML17139B989), and gave the State 30 days to 
respond. The State did not respond. The NRC also consulted with the 
Fish and Wildlife Service by letter dated July 15, 2016 (ADAMS 
Accession No. ML16197A054). However, the NRC staff has determined that 
consultation under ESA Section 7 is not required because the proposed 
action is administrative/procedural in nature and will not affect 
listed species or critical habitat (ADAMS Accession No. ML17135A062).

III. Finding of No Significant Impact

    The NRC staff has determined that the proposed action, the review 
and approval of Luminant Power's initial and updated DFPs, submitted in 
accordance with 10 CFR 72.30(b) and 72.30(c), will not authorize or 
result in changes to licensed operations or maintenance activities, or 
changes in the types, characteristics, or quantities of radiological or 
non-radiological effluents released into the environment from the 
ISFSI, or result in the creation of any solid waste. Moreover, the 
approval of the DFPs will not authorize any construction activity, 
facility modification, or any other land-disturbing activity. The NRC 
staff has concluded that the proposed action is a procedural and 
administrative action and as such, that the proposed action will not 
have a significant effect on the quality of the human environment. 
Therefore, the NRC staff has determined not to prepare an EIS for the 
proposed action but will issue this FONSI.
