Connecticut Yankee Atomic Power Company; Haddam Neck Plant;
Environmental Assessment and Finding of No Significant Impact
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of an exemption in response to the April 24, 2023, request
from Connecticut Yankee Atomic Power Company (CYAPCO), for the Haddam
Neck Plant (HNP or Haddam Neck) located in East Hampton, Connecticut.
The proposed exemption from NRC regulations, if granted, would permit
CYAPCO to make withdrawals from a segregated account within Haddam
Neck's overall nuclear decommissioning trust (NDT), on an annual basis,
for spent nuclear fuel (SNF) and Greater than Class C (GTCC) waste
management and non-radiological site restoration without prior
notification to the NRC. The NRC staff is issuing an environmental
assessment (EA) and finding of no significant impact (FONSI) associated
with the proposed exemption.

SUPPLEMENTARY INFORMATION:
I. Introduction
By letter dated April 24, 2023, CYAPCO submitted a request to the
NRC for an exemption from paragraphs 50.82(a)(8)(i)(A) and 10 CFR
50.75(h)(2) of title 10 of the Code of Federal Regulations (10 CFR) for
the Haddam Neck Independent Spent Fuel Storage Installation \1\
(ISFSI).
---------------------------------------------------------------------------
\1\ As discussed in this document, the Haddam Neck ISFSI sits on
the former site of HNP, which CYAPCO finished decommissioning in
2007. Although only the Haddam Neck ISFSI remains on the site,
CYAPCO's 10 CFR part 50 license, Facility Operating License No. DPR-
61 remains in effect. Because CYAPCO requested an exemption from the
requirements of 10 CFR part 50, this would be an exemption for
CYAPCO's 10 CFR part 50 license rather than for CYAPCO's 10 CFR part
72 general license. Therefore, although CYAPCO's submission
requested an exemption for the Haddam Neck ISFSI, the NRC staff will
consider it a request for an exemption for HNP.
---------------------------------------------------------------------------
CYAPCO has established a separate (segregated) account within its
over-arching NDT, entitled ``ISFSI Radiological Decom,'' that
identifies the funds for radiological decommissioning of the ISFSI
apart from the larger balance of funds in the NDT allocated for ongoing
management of SNF and GTCC waste and for non-radiological site
restoration activities. Although 10 CFR 50.82 applies to the segregated
account, it does not apply to the overall NDT.
If granted, the exemptions from 10 CFR 50.82(a)(8)(i)(A) and
50.75(h)(2) would permit CYAPCO to make withdrawals from the segregated
account, on an annual basis, for SNF and GTCC waste management and non-
radiological site restoration without prior notification to the NRC.
More specifically, with this exemption, CYAPCO would be able to
annually transfer funds exceeding 110 percent of the inflation-adjusted
decommissioning cost estimate (DCE), described in 10 CFR 50.75, from
the segregated account to its overarching NDT and use those funds for
SNF and GTCC waste management and non-radiological site restoration.
HNP began commercial operations in January 1968, and ceased power
production in December 1996. CYAPCO initiated decommissioning shortly
thereafter. In July 2007, HNP completed its final decommissioning of
the reactor site, except for the ISFSI, which included dismantling and
removing all reactor plant related facilities. As a result, only the
ISFSI remains at the old plant site of HNP in East Hampton,
Connecticut.
By letter dated November 26, 2007, NRC approved the release of most
portions of the HNP site from the 10 CFR part 50 license (DPR-61) for
unrestricted release, except for the ISFSI and immediately surrounding
areas. Under its 10 CFR part 72 general license, HNP is authorized to
possess, and store SNF at the permanently shut down and decommissioned
facility under the provision of 10 CFR part 72, subpart K, ``General
License for Storage of Spent Fuel at Power Reactor Sites.''
The NRC staff is performing both a safety evaluation and an
environmental review to determine whether to grant this exemption
request. The NRC staff will prepare a separate safety evaluation report
(SER) to document its safety review and analysis. The NRC's SER will
evaluate the proposed exemption for reasonable assurance of adequate
protection of public health and safety, and the common defense and
security. This EA documents the environmental review which the NRC
staff prepared in accordance with 10 CFR 51.21 and 51.30(a). The NRC's
decision whether to grant the exemption will be based on the results of
the NRC staff's review as documented in this EA, and the staff's safety
review to be documented in the SER.
II. Environmental Assessment
By letter dated April 24, 2023, CYAPCO submitted a request to the
NRC for an exemption from 10 CFR 50.82(a)(8)(i)(A) and 10 CFR
50.75(h)(2). If granted, the proposed exemption from 10 CFR
50.82(a)(8)(i)(A) and 50.75(h)(2) would permit CYAPCO to make
withdrawals from the segregated account, on an annual basis, for SNF
and GTCC waste management and non-radiological site restoration without
prior notification to the NRC. More specifically, with this exemption,
CYAPCO would be able to annually transfer funds exceeding 110 percent
of the inflation-adjusted DCE, described in 10 CFR 50.75, from the
segregated account to its overarching NDT and use those funds for SNF
and GTCC waste management and non-radiological site restoration
activities.
Need for the Proposed Action
As required by 10 CFR 50.82(a)(8)(i)(A), decommissioning trust
funds may be used by the licensee if the withdrawals are for legitimate
decommissioning activity expenses, consistent with the definition of
decommissioning in 10 CFR 50.2. This definition addresses radiological
decommissioning and does not include activities associated with
management of SNF and GTCC waste or non-radiological site restoration.
Similarly, the requirements of 10 CFR 50.75(h)(2) restrict the use of
decommissioning trust fund disbursements (other than for ordinary and
incidental expenses) to decommissioning expenses until final
decommissioning has been completed.
CYAPCO stated that it has established a segregated account,
entitled ``ISFSI Radiological Decom,'' within its over-arching NDT,
that identifies the funds for radiological decommissioning of the
ISFSI. This segregated account is apart from the larger balance of
funds in the NDT allocated for ongoing management of SNF and GTCC waste
and for other non-radiological site restoration activities. Therefore,
exemption from 10 CFR 50.82(a)(8)(i)(A) and 50.75(h)(2) is needed to
allow CYAPCO to use funds from the segregated account for SNF and GTCC
waste management and other non-radiological site restoration
activities.
In its Decommissioning Funding Assurance Status Report dated March
6, 2023, CYAPCO stated that, its inflation-adjusted DCE for the
radiological decommissioning of the ISFSI is approximately $7.1 million
in 2022 dollars. It asserted this amount provides reasonable assurance
of adequate funding to complete the NRC required decommissioning
activities. In the same report, CYAPCO reported that the segregated
``ISFSI Radiological Decom'' account had $46.4 million in 2022 dollars
as of December 31, 2022. More specifically, in its exemption request,
CYAPCO provided a table showing $7,070,450, in 2022 dollars, as the
inflation-adjusted DCE. CYAPCO's exemption request further stated that
the segregated account has a balance of $47,609,309 as of December 31,
2022, meaning that the segregated account had a balance of $40,538,859,
or 573 percent beyond the inflation-adjusted DCE.
CYAPCO stated that, if the exemption is granted, funds in its
segregated account which exceed 110 percent of the inflation-adjusted
DCE for the radiological decommissioning of the ISFSI would be
transferred to the overarching NDT on an annual basis without prior NRC
notification. CYAPCO would then use those funds for SNF and GTCC waste
management and non-radiological site restoration, which in turn, would
allow CYAPCO to return its additional excess funds in the overarching
NDT to its customers as part of future rate cases with the Federal
Energy Regulatory Commission.
[[Page 46172]]
The requirements of 10 CFR 50.75(h)(2) further provide that, except
for withdrawals being made under 10 CFR 50.82(a)(8) or for payments of
ordinary administrative costs and other incidental expenses of the NDT
in connection with the operation of the NDT, no disbursement may be
made from the NDT without written notice to the NRC at least 30 working
days in advance. Therefore, an exemption from 10 CFR 50.75(h)(2) is
also needed to allow CYAPCO to use funds from the segregated account
for SNF and GTCC waste management and non-radiological site restoration
activities without prior NRC notification.
Environmental Impacts of the Proposed Action
The proposed action involves an exemption from requirements that
are of financial and/or administrative nature and that do not have an
impact on the environment. Before the NRC could approve the proposed
action, it would have to conclude that there is reasonable assurance
that adequate funds are available in the segregated account to complete
all activities associated with radiological decommissioning as well as
SNF and GTCC waste management and non-radiological site restoration.
Therefore, there would be no decrease in safety associated with the use
of funds from the segregated account to also fund activities associated
with SNF and GTCC waste management and non-radiological site-
restoration.
The requested exemption from the requirements of 10 CFR
50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(2), if approved, would allow
transfers on an annual basis. CYAPCO stated that it will continue to
provide its annual decommissioning funding assurance status report in
accordance with 10 CFR 50.75(f)(1) and (2) and 10 CFR 50.82(a)(8)(v)
and (vi) requirements. These reports provide the NRC staff with
awareness of, and the ability to act on, any actual or potential
funding deficiencies. As the proposed exemption would not affect these
requirements, the NRC staff would have tools available for any
potential funding deficiencies. Since the exemption would allow CYAPCO
to use funds from the segregated account that are in excess of those
required for radiological decommissioning, the adequacy of funds
dedicated for radiological decommissioning would not be affected by the
proposed exemption. Therefore, there is reasonable assurance that there
would be no environmental impact due to lack of adequate funding for
radiological decommissioning.
Further, there are no new accident precursors created by using the
excess funds from the segregated account for SNF and GTCC waste
management and non-radiological site-restoration. The exemption, if
granted, would be financial and/or administrative in nature. Thus, the
probability of postulated accidents is not increased. Also, the
consequences of postulated accidents are not increased. No changes are
being made in the types or amounts of effluents that may be released
offsite. There is no significant increase in occupational or public
radiation exposure. Therefore, the requested exemption will not present
an undue risk to the public health and safety.
With regard to potential non-radiological impacts, the proposed
action would have no direct impacts on land use or water resources,
including terrestrial and aquatic biota, as it involves no new
construction or modification of plant operational systems. There would
be no changes to the quality or quantity of non-radiological effluents.
In addition, there would be no noticeable effect on socioeconomic
conditions in the region, no environmental justice impacts, no air
quality impacts, and no impacts to historic and cultural resources from
the proposed action. Therefore, there are no significant non-
radiological environmental impacts associated with the proposed action.
For these reasons, the NRC concludes there are no significant
environmental impacts associated with the proposed exemption request.
Environmental Impacts of the Alternatives to the Proposed Action
In addition to the proposed action, the NRC staff also considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the exemption request would result in no change in current
environmental impacts. The environmental impacts of the proposed action
and the alternative action would be similar.
Alternative Use of Resources
There are no unresolved conflicts concerning alternative uses of
available resources under the proposed action.
Agencies Consulted
By email dated April 5, 2024, the NRC provided a copy of the draft
EA to the Connecticut Department of Energy and Environmental
Protection, Radiation Division, for review. By email dated May 6, 2024,
Connecticut Department of Energy and Environmental Protection,
Radiation Division, indicated that it had no comments.
Endangered Species Act Section 7 Consultation
Section 7 of the Endangered Species Act of 1973, as amended (ESA),
requires Federal agencies to consult with the U.S. Fish and Wildlife
Service or National Marine Fisheries Service regarding actions that may
affect listed species or designated critical habitats. The ESA is
intended to prevent further decline of endangered and threatened
species and restore those species and their critical habitat.
The NRC staff determined that a consultation under section 7 of the
ESA is not required because the proposed action will not affect listed
species or critical habitat.
National Historic Preservation Act Section 106 Consultation
Section 106 of the National Historic Preservation Act (NHPA)
requires Federal agencies to consider the effects of their undertakings
on historic properties. As stated in the NHPA, historic properties are
any prehistoric or historic district, site, building, structure, or
object included in, or eligible for inclusion in the National Register
of Historic Places.
The NRC determined that the scope of activities described in this
exemption request do not have the potential to cause effects on
historic properties because the NRC's approval of this exemption
request will not authorize new construction or land disturbance
activities. The NRC staff also determined that the proposed action is
not a type of activity that has the potential to impact historic
properties because the proposed action would occur within the
established HNP site boundary. Therefore, in accordance with 36 CFR
800.3(a)(1), no consultation is required under section 106 of NHPA.
III. Finding of No Significant Impact
The environmental impacts of the proposed action--an exemption from
the requirements of 10 CFR 50.82(a)(8)(i)(A) and 10 CFR 50.75(h)(2)
allowing CYAPCO to make withdrawals from the segregated account, on an
annual basis, for SNF and GTCC waste management and non-radiological
site restoration without prior notification to the NRC--have been
reviewed under the requirements in 10 CFR part 51, which implement the
National Environmental Policy Act of 1969, as amended.
The proposed exemption would not have a significant adverse effect
on the probability of an accident occurring and would not have any
significant radiological or non-radiological impacts. The proposed
exemption involves an
[[Page 46173]]
exemption from requirements that are of a financial and/or
administrative nature and would not have an impact on the human
environment. Consistent with 10 CFR 51.21, the NRC conducted the EA for
the proposed exemption, and this FONSI incorporates by reference the EA
included in this document. Therefore, the NRC concludes that the
proposed action will not have significant effects on the quality of the
human environment. Accordingly, the NRC has determined not to prepare
an environmental impact statement for the proposed action.
