SUPPLEMENTARY INFORMATION: lotter on DSK11XQN23PROD with NOTICES1 I. Introduction The NRC is considering an amendment of ACO’s Special Nuclear Materials License No. SNM–2011, which authorized the operation of the HALEU cascade at the ACP in Pike County, Ohio in June 2021. If approved, the amendment would increase ACO’s licensed material possession limits to support the production of HALEU UF6 from 600 kg to approximately 1,400 kg and would allow ACO to store approximately 1,400 kg of HALEU UF6 at the ACP. As required in section 51.21 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions,’’ the NRC developed an EA for the proposed license amendment to increase the possession limits for licensed material at the ACP. Based on the results of the EA summarized in this notice, the NRC has determined not to prepare an environmental impact statement (EIS) for the amendment and is issuing a FONSI. ACO is producing HALEU for the U.S. Department of Energy (DOE). HALEU is uranium that has been enriched so that the concentration of the fissile isotope U–235 is between 5 and 20 percent of the mass of the uranium. The DOE established a 3-phase contract with ACO to deploy a cascade of 16 operating centrifuges and two spare centrifuges to demonstrate the capability to enrich uranium to the higher level. The NRC approved the license amendment for the operation of this HALEU cascade in June 2021. The expiration date of the current phase (phase 2) of the contract that DOE has funded is December 31, 2024. Phase 3, involving up to three, 3year periods of operation of the HALEU cascade, would need Congressional VerDate Sep<11>2014 16:59 Sep 18, 2024 Jkt 262001 appropriations and the approval of the NRC to move forward. II. Summary of Environmental Assessment Description of the Proposed Action The proposed action would increase the authorized limits for possession of licensed material for the purpose of producing approximately 1,400 kg of HALEU UF6 from the current HALEU UF6 production amount of 600 kg. This amendment would be effective until DOE’s contract with ACO expires on December 31, 2024. If ACO requests an extension of the HALEU cascade program beyond December 31, 2024, the NRC would need to conduct a separate licensing and environmental review for that extension. ACO operates the HALEU cascade in a building that previously housed the former Lead Cascade Facility, which was decommissioned in 2018. ACO does not propose to construct new buildings, conduct ground-disturbing activities, ship HALEU offsite, or make changes to the HALEU centrifuge cascade design that the NRC approved in 2021. The proposed action is in accordance with the licensee’s application dated February 13, 2023, as supplemented by letters dated June 29, 2023, February 15, 2024, and March 7, 2024. Need for the Proposed Action The proposed amendment would allow ACO to continue demonstrating the capability to enrich uranium-235 up to a level necessary to produce HALEU. ACO is under contract with DOE to enrich uranium and produce HALEU using the 16-centrifuge enrichment cascade constructed for this purpose. Environmental Impacts of the Proposed Action The NRC staff assessed the potential environmental impacts from the increase in possession limits on land use; historic and cultural resources; visual and scenic resources; climatology, meteorology and air quality; geology and soils; water resources; ecological resources; socioeconomics; noise; traffic and transportation; public and occupational health and safety; and waste management. The NRC staff determined that the proposed action would not affect most resource areas and would not have significant impacts on air quality, transportation, occupational health and safety, and waste management. ACO would not make changes to the enrichment processes or to the outside portions of buildings. All PO 00000 Frm 00087 Fmt 4703 Sfmt 4703 HALEU produced would be stored onsite. All enrichment activities would continue to take place indoors, resulting in no changes to noise levels. Because operations would continue entirely inside buildings, including storage of additional enriched UF6 depleted UF6, and wastes, and because the current rate of HALEU production would not change, there would be no change to potential impacts on public health and safety. Because additional employees would not be required for the proposed action, there would be no change to socioeconomic impacts already assessed. The NRC staff further concluded in the EA that the potential impacts on air quality, occupational health and safety, waste management, and transportation are bounded by the impacts assessed in previous NRC environmental assessments, as documented in the NRC’s 2021 EA for the approval of the HALEU demonstration program. Environmental Impacts of the Alternatives to the Proposed Action As an alternative to the proposed action, the staff considered denial of the proposed action (i.e., the ‘‘no-action’’ alternative). Under the no-action alternative, the NRC would deny ACO’s request and ACO’s HALEU production level would remain at 600 kg. The noaction alternative would not permit ACO to meet the terms of DOE’s contract with ACO. The potential environmental impacts of denying the request would be unchanged from the impacts as assessed in the NRC’s 2021 EA for the approval of the HALEU demonstration program. Agencies and Persons Consulted In accordance with NRC policy, on June 27, 2024, the staff consulted with the Ohio Emergency Management Agency, Ohio Environmental Protection Agency, and Ohio Department of Health regarding the EA and FONSI. On July 5, 2024, the staff consulted with U.S. Environmental Protection Agency (EPA) Region 5 regarding the EA and FONSI. In addition, on July 5, 2024, the staff provided a courtesy notification of the proposed action to the Ohio State Historic Preservation Office. The NRC received no comments on the EA. III. Finding of No Significant Impact Based on its review of the proposed license amendment request, in accordance with the requirements of 10 CFR part 51, the NRC staff has determined that approving the requested license amendment to increase the possession limits of licensed material for the HALEU E:\FR\FM\19SEN1.SGM 19SEN1 76873 Federal Register / Vol. 89, No. 182 / Thursday, September 19, 2024 / Notices demonstration and operations program would not significantly affect the quality of human environment. No significant radiological or nonradiological impacts are expected from the proposed action. Therefore, the NRC staff has determined that, pursuant to 10 CFR 51.31, ‘‘Determinations based on environmental assessment,’’ preparation of an EIS is not required for the proposed action, and pursuant to 10 CFR 51.32, ‘‘Finding of no significant impact,’’ a FONSI is appropriate. In accordance with 10 CFR 51.32(a)(4), this FONSI incorporates the EA summarized in this notice by reference. IV.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is considering an amendment of ACO's Special Nuclear 
Materials License No. SNM-2011, which authorized the operation of the 
HALEU cascade at the ACP in Pike County, Ohio in June 2021. If 
approved, the amendment would increase ACO's licensed material 
possession limits to support the production of HALEU UF6 
from 600 kg to approximately 1,400 kg and would allow ACO to store 
approximately 1,400 kg of HALEU UF6 at the ACP. As required 
in section 51.21 of title 10 of the Code of Federal Regulations (10 
CFR), ``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions,'' the NRC developed an EA for the 
proposed license amendment to increase the possession limits for 
licensed material at the ACP. Based on the results of the EA summarized 
in this notice, the NRC has determined not to prepare an environmental 
impact statement (EIS) for the amendment and is issuing a FONSI.
    ACO is producing HALEU for the U.S. Department of Energy (DOE). 
HALEU is uranium that has been enriched so that the concentration of 
the fissile isotope U-235 is between 5 and 20 percent of the mass of 
the uranium. The DOE established a 3-phase contract with ACO to deploy 
a cascade of 16 operating centrifuges and two spare centrifuges to 
demonstrate the capability to enrich uranium to the higher level. The 
NRC approved the license amendment for the operation of this HALEU 
cascade in June 2021. The expiration date of the current phase (phase 
2) of the contract that DOE has funded is December 31, 2024. Phase 3, 
involving up to three, 3-year periods of operation of the HALEU 
cascade, would need Congressional appropriations and the approval of 
the NRC to move forward.

II. Summary of Environmental Assessment

Description of the Proposed Action

    The proposed action would increase the authorized limits for 
possession of licensed material for the purpose of producing 
approximately 1,400 kg of HALEU UF6 from the current HALEU 
UF6 production amount of 600 kg. This amendment would be 
effective until DOE's contract with ACO expires on December 31, 2024. 
If ACO requests an extension of the HALEU cascade program beyond 
December 31, 2024, the NRC would need to conduct a separate licensing 
and environmental review for that extension.
    ACO operates the HALEU cascade in a building that previously housed 
the former Lead Cascade Facility, which was decommissioned in 2018. ACO 
does not propose to construct new buildings, conduct ground-disturbing 
activities, ship HALEU offsite, or make changes to the HALEU centrifuge 
cascade design that the NRC approved in 2021.
    The proposed action is in accordance with the licensee's 
application dated February 13, 2023, as supplemented by letters dated 
June 29, 2023, February 15, 2024, and March 7, 2024.

Need for the Proposed Action

    The proposed amendment would allow ACO to continue demonstrating 
the capability to enrich uranium-235 up to a level necessary to produce 
HALEU. ACO is under contract with DOE to enrich uranium and produce 
HALEU using the 16-centrifuge enrichment cascade constructed for this 
purpose.

Environmental Impacts of the Proposed Action

    The NRC staff assessed the potential environmental impacts from the 
increase in possession limits on land use; historic and cultural 
resources; visual and scenic resources; climatology, meteorology and 
air quality; geology and soils; water resources; ecological resources; 
socioeconomics; noise; traffic and transportation; public and 
occupational health and safety; and waste management. The NRC staff 
determined that the proposed action would not affect most resource 
areas and would not have significant impacts on air quality, 
transportation, occupational health and safety, and waste management. 
ACO would not make changes to the enrichment processes or to the 
outside portions of buildings. All HALEU produced would be stored 
onsite. All enrichment activities would continue to take place indoors, 
resulting in no changes to noise levels. Because operations would 
continue entirely inside buildings, including storage of additional 
enriched UF6 depleted UF6, and wastes, and 
because the current rate of HALEU production would not change, there 
would be no change to potential impacts on public health and safety. 
Because additional employees would not be required for the proposed 
action, there would be no change to socioeconomic impacts already 
assessed. The NRC staff further concluded in the EA that the potential 
impacts on air quality, occupational health and safety, waste 
management, and transportation are bounded by the impacts assessed in 
previous NRC environmental assessments, as documented in the NRC's 2021 
EA for the approval of the HALEU demonstration program.

Environmental Impacts of the Alternatives to the Proposed Action

    As an alternative to the proposed action, the staff considered 
denial of the proposed action (i.e., the ``no-action'' alternative). 
Under the no-action alternative, the NRC would deny ACO's request and 
ACO's HALEU production level would remain at 600 kg. The no-action 
alternative would not permit ACO to meet the terms of DOE's contract 
with ACO. The potential environmental impacts of denying the request 
would be unchanged from the impacts as assessed in the NRC's 2021 EA 
for the approval of the HALEU demonstration program.

Agencies and Persons Consulted

    In accordance with NRC policy, on June 27, 2024, the staff 
consulted with the Ohio Emergency Management Agency, Ohio Environmental 
Protection Agency, and Ohio Department of Health regarding the EA and 
FONSI. On July 5, 2024, the staff consulted with U.S. Environmental 
Protection Agency (EPA) Region 5 regarding the EA and FONSI. In 
addition, on July 5, 2024, the staff provided a courtesy notification 
of the proposed action to the Ohio State Historic Preservation Office. 
The NRC received no comments on the EA.

III. Finding of No Significant Impact

    Based on its review of the proposed license amendment request, in 
accordance with the requirements of 10 CFR part 51, the NRC staff has 
determined that approving the requested license amendment to increase 
the possession limits of licensed material for the HALEU

[[Page 76873]]

demonstration and operations program would not significantly affect the 
quality of human environment. No significant radiological or non-
radiological impacts are expected from the proposed action. Therefore, 
the NRC staff has determined that, pursuant to 10 CFR 51.31, 
``Determinations based on environmental assessment,'' preparation of an 
EIS is not required for the proposed action, and pursuant to 10 CFR 
51.32, ``Finding of no significant impact,'' a FONSI is appropriate. In 
accordance with 10 CFR 51.32(a)(4), this FONSI incorporates the EA 
summarized in this notice by reference.
