SUPPLEMENTARY INFORMATION:
I. Introduction By letter dated January 5, 2018 (ADAMS Accession Number ML18025B285),
American Centrifuge Operating, LLC (ACO or the licensee) requested NRC approval of ACOs Decommissioning Plan (DP). The DP contains ACOs proposed Release Criteria (RC) and Final Status Survey (FSS) design. The Lead Cascade Facility (LCF) is located at the Portsmouth Gaseous Diffusion Plant (PORTS) site in Pike County, Ohio. The PORTS site is owned by the U.S. Department of Energy (DOE), and the DOE leases portions of the PORTS site, including the LCF buildings, to the licensee. The NRC staff has prepared an Environmental Assessment (EA) (ADAMS Accession Number ML18204A294) as part of its review of this proposed action in accordance with the requirements in part 51 of title 10 of the Code of Federal Regulations (10 CFR),
Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions and associated staff guidance. The NRC has concluded that the proposed action will not have a significant effect on the quality of the human environment.
II. Summary of the Environmental Assessment Description of the Proposed Action The proposed action is to review and approve ACOs DP which provides the proposed RC and FSS design. The RC are regulatory limits identified in 10 CFR part 20.1402. The FSS is performed by the licensee to verify that residual contamination levels are less than these limits.
Need for the Proposed Action By letter dated March 2, 2016, the licensee notified the NRC of its decision to permanently cease LCF operations (ADAMS Accession Number ML16074A405). In preparation for decommissioning of the LCF, termination of license SNM-7003, and potential future release of the site and return to DOE as outlined in the lease agreement, ACO has performed clean-up and survey activities.
Environmental Impacts of the Proposed Action The NRC staff evaluated the potential environmental impacts associated with the proposed action, and has performed its environmental review in accordance with the requirements in 10 CFR part 51 and associated staff guidance. As detailed in the EA, the staff reviewed relevant information submitted by the licensee and consulted with the Ohio State Historic Preservation Office (SHPO), the Osage Nation, Advisory Council on Historic Preservation (ACHP), and the State of Ohio Department of Health (ODH).
Survey activities for the FSS have occurred inside the LCF buildings, and no land disturbance activities were involved or are planned. Therefore, the NRC staff considers that there would be no impacts to the following resources areas: land use, geology and soils, water resources, ecology, meteorology, climate, air quality, noise, transportation, waste management, visual and scenic resources, and socioeconomic resources.
The NRC staff evaluated the radiological impacts to workers and the public. The staff found that the radiological doses to workers would be within the dose limits specified in 10 CFR 20.1201, Occupational dose limits to adults, and that radiological doses to the public would be indistinguishable when compared to background radiation.

The NRC staff also evaluated the cumulative impacts by identifying past, present, and reasonably foreseeable future actions at DOEs Piketon, Ohio site, and the incremental impacts of ACOs proposed action. The staff determined that the proposed action would not significantly contribute to cumulative impacts. The staff also determined that the proposed action would not affect federally-listed endangered or threatened species or their critical habitats, if present.
Environmental Impacts of the Alternatives to the Proposed Action As an alternative to the proposed action, the staff considered denial of the proposed action and requesting ACO to submit a revised DP (i.e., the no-action alternative). Under the no-action alternative, the LCF FSS and RC would not be approved and license termination would not be possible. The NRC considers the environmental impacts of this alternative to be similar to those of the proposed action.
The no-action alternative does not comply with the licensee's commitments made during licensing or the decommissioning requirements of 10 CFR 70.38 and does not provide any environmental benefit. The NRC staff concludes that not approving the provided RC and FSS, which meet the regulatory requirements, is not a reasonable alternative to approving the proposed action.
Agencies and Persons Consulted By letter dated June 12, 2018 (ADAMS Accession Number ML18130A468), the staff consulted with the ODH regarding the environmental impact of the proposed action.
By letter dated July 6, 2018, the ODH replied indicating that they had no comments on the draft EA (ADAMS Accession Number ML18130A468). The NRC staff also consulted 5
with the Ohio SHPO by letter dated April 9, 2018 (ADAMS Accession Number.
ML18078B230). The Ohio SHPO responded by letter dated May 16, 2018, stating that they could not concur with a finding of No Adverse Effect for the proposed action and recommended that NRC initiate and carry out consultation and contact the ACHP (ADAMS Accession Number ML18155A296). On June 11, 2018, a conference call was held between the Ohio SHPO, the ACHP, and the NRC to discuss the concerns expressed in the SHPOs May 16, 2018, letter. During the call the ACHP expressed its agreement with the NRC that the requested action falls under 36 CFR 800.3(a)(1), No potential to cause effects, which states, If the undertaking is a type of activity that does not have the potential to cause effects on historic properties, assuming such properties were present, the agency official has no further obligations under Section 106 or this part. The NRC sent a letter, dated July 16, 2018, to the Ohio SHPO summarizing the conference call and concluding Section 106 consultation (ADAMS Accession Number ML18171A218). By letter dated April 11, 2018, the NRC initiated Section 106 consultation under the National Historic Preservation Act with the Osage Nation. In their reply, the Osage Nation stated it concurred with the NRC determination that the proposed DP most likely would not adversely affect any sacred properties and/or properties of cultural significance to the Nation, and also stated, [t]he Osage Nation has no further concern with this project (ADAMS Accession Number ML18158A263).
III. Finding of No Significant Impact In accordance with the requirements in 10 CFR part 51, the NRC staff has concluded that the proposed action will not significantly affect the quality of the human environment. Therefore, the staff finds, pursuant to 10 CFR 51.31, that preparation of 7
an environmental impact statement is not required for the proposed action, and that a finding of no significant impact is appropriate.
Dated at Rockville, Maryland, this 26th day of July 2018.
