SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is considering issuance of an amendment of License No. 45-
23645-01NA, issued to the Department of the Navy (DON). Therefore, as 
required by Part 51 of title 10 of the Code of Federal Regulations (10 
CFR), the NRC performed an EA. Based on the results of the EA that 
follows, the NRC has determined not to prepare an environmental impact 
statement for the license amendment and is issuing a FONSI.

II. Environmental Assessment

Introduction

    In accordance with License Condition, 21.W of NRC Radioactive 
Materials License No. 45-23645-01NA (Master Materials License (MML)), 
the DON incorporates a permitting program for the use of licensed 
material. Individual entities that are subject to this permitting 
program are called permittees. Each permittee associated with this MML, 
consistent with the requirements in 10 CFR 30.36(h), is required to 
complete decommissioning as soon as practicable but no later than 24 
months following the initiation of decommissioning.
    The DON has requested approval to extend the 24-month time period 
specified in 10 CFR 30.36(h)(1) and (2) for completing decommissioning 
and requesting termination of permitted activities under its MML beyond 
the 24-month time limit for decommissioning. The NRC may approve such a 
request consistent with the criteria specified in 10 CFR 30.36(i).

Description of the Proposed Action

    The proposed action would amend the DON's MML to allow an 
alternative schedule for decommissioning and requesting termination of 
permitted activities. By letter dated September 15, 2020, (ADAMS 
Accession No. ML20260H015) the DON requested a 10-year time limit be 
applied to the requirements in 10 CFR 30.36(h)(1) and (2) with no other 
stipulations. As a result of the information submitted by the DON to 
support its request, the NRC staff only analyzed potential 
environmental issues related to a shorter 5-year time limit.
    During the review of the DON's request, the NRC staff identified 
some concerns related to the sites where groundwater could be 
implicated in the decontamination and termination of a permit. In 
response to this information, the NRC proposed to limit the extension 
of decontamination and termination of permitted site to those where no 
potential for groundwater contamination exists through a license 
condition. The DON agreed to this condition and its limitation in a 
letter dated February 6, 2021 (ADAMS Accession No. ML21048A250). As a 
result, the NRC staff's analysis of potential environmental impacts was 
limited to the 5-year time limit of the decommission and termination 
process for sites without the potential to involve groundwater. The NRC 
staff, however, is not taking a position and did not perform an 
assessment of potential environmental impacts from extending 
decommissioning and termination of permitted sites with potential 
groundwater concerns to a 5-year time limit.

Purpose and Need for the Proposed Action

    The purpose of the proposed action is to align the DON's 
responsibilities for timely decommissioning and termination of permits 
as specified in 10 CFR 30.36(h)(1) and (2) with the Federal budgeting 
process. This purpose is consistent with the guidance for operators of 
Federal facilities in NUREG-1757 (see Section 2.6.1) (ADAMS Accession 
No. ML12048A683).
    The need for the proposed action is to comply with NRC regulations. 
The NRC is fulfilling its responsibilities under the Atomic Energy Act 
to make a decision on a proposed license amendment for an alternative 
schedule for completion of decommissioning and permit termination that 
ensures protection of the public health and safety and environment.

Environmental Impacts of the Proposed Action

    The NRC staff reviewed the information provided by the DON to 
support their 10 CFR 30.36(h)(1) and (2) alternative decommissioning 
and license (or permit, in this case) termination schedule request. As 
documented in the Technical Evaluation Report (TER) (ADAMS Accession 
No. ML21054A252), the NRC staff evaluated the five criteria specified 
in 10 CFR 30.36(i). Based on its evaluation of 10 CFR 30.36(i)(5), the 
NRC staff determined that the 24-month decommissioning timeline is 
inconsistent with the availability of funds to the DON for 
decommissioning activities.
    Under the MML, the DON is currently allowed to permit any 
radionuclide to carry out activities at its permitted sites. The DON's 
permitting authority is limited to quantities that are less than the 
critical mass quantities specified in 10 CFR 150.11. The NRC staff 
notes that the DON is not requesting any changes to its licensed 
activities or other decommissioning processes previously evaluated and 
approved by the NRC staff.
    The NRC staff evaluated potential environmental impacts resulting 
from increasing the time to complete the actions in 10 CFR 30.36(h)(1) 
and (2) from 2 years to 5 years. The NRC staff considered radionuclides 
with short half-lives (t1/2) (e.g., technicium-99, 
t1/2 = 6 hours) and long half-lives (e.g., U-235, 
t1/2 = 700 million years). Over the 3 additional years (5 
years total), radionuclides with very short half-lives will decay to 
levels not detectable with common radiation detectors. During the same 
time frame, radionuclides with very long half-lives will undergo no 
appreciable radioactive decay and will therefore be at the same 
activity levels. The NRC staff did not identify activities that would 
result in a significant increase in the potential for or consequences 
from radiological accidents involving the licensed material as a result 
of the proposed action. The NRC staff considered the potential for any 
contamination to spread or migrate off the permitted site during the 
additional 3-years that would be allowed for decommissioning and 
termination. For sites without any potential groundwater contamination, 
the NRC staff did not identify any reasonable scenarios for 
contamination to migrate off-site given the DON ability to maintain 
institutional controls over the permitted sites. For sites with the 
potential for groundwater contamination, the NRC staff determined that 
it did not have sufficient information to complete a generic analysis 
of these permitted sites at this time. Consistent with the condition 
imposed on the amendment to sites without groundwater contamination, 
the NRC staff did not perform additional environmental analysis of 
these type of sites.
    As a Federal agency, the DON or a successor agency would continue 
to be able to maintain institutional controls over the permitted sites 
and perform the necessary denomination and termination consistent with 
its appropriations. Therefore, the short extension from a 2-year period 
to the 5-year period is unlikely to result in abandonment of a site or 
affect the DON's ability to perform decommissioning.
    Based on the previously noted analysis, the NRC staff finds that 
the environmental impacts of the proposed action are not significant.

Alternatives to the Proposed Action

    As an alternative to the proposed action, the NRC staff considered 
the no-action alternative in which the NRC staff would deny the 
extension request. Denial of the request would require the DON to 
request separate extensions for most, if not all, of its permittees. 
This would place an undue burden on the DON and the NRC staff 
associated with the licensing actions required for these separate 
extension requests as the criteria to be considered by the NRC for 
approval would be the same or similar as those for the proposed action. 
In addition, the DON would not be able to comply with the timeliness 
requirements of 10 CFR 30.36(h)(1) and (2) due to the appropriation 
process. Therefore, the no-action alternative was not further 
considered.

Consultations

    Section 7 of the Endangered Species Act (Act) [16 U.S.C. 1531 et 
seq.] outlines the procedures for Federal interagency cooperation to 
conserve Federally listed species and designated critical habitats. 
Section 7(a)(2) states that each Federal agency shall, in consultation 
with the Secretary, insure that any action they authorize, fund, or 
carry out is not likely to jeopardize the continued existence of a 
listed species or result in the destruction or adverse modification of 
designated critical habitat. The NRC staff has determined that a 
Section 7 consultation is not required because the proposed action is 
administrative/procedural in nature and will not affect listed species 
or critical habitat. The NRC staff has also determined that the 
proposed action is not a type of activity that have potential to cause 
effects on historic properties because they are administrative/
procedural actions. Therefore, no additional consultation is required 
under Section 106 of the National Historic Preservation Act.

Conclusion

    Based on its review, the NRC staff has concluded that the proposed 
action complies with 10 CFR part 30. NRC has prepared this EA in 
support of the proposed license amendment to approve an alternative 
decommissioning schedule. On the basis of the EA, NRC has concluded 
that the environmental impacts from the proposed action are expected to 
be insignificant and has determined that preparation of an 
environmental impact statement for the proposed action is not required.

III. Finding of No Significant Impact

    On the basis of the EA, the NRC concludes that the proposed action 
will not have a significant effect on the quality of the human 
environment. Accordingly, the NRC has determined not to prepare an 
environmental impact statement for the proposed action.
