# SUPPLEMENTARY INFORMATION:

                    By letter dated October 7, 2022, Cimarron Environmental Response Trust (CERT) submitted to the NRC an application (ADAMS Accession No. ML22284A145) to amend Special Nuclear Materials License No. SNM-928, which authorizes the possession of byproduct, source, and special nuclear material. The amendment requests approval of Revision 3 of the proposed facility decommissioning plan (DP) for the Cimarron facility in Guthrie, Oklahoma, and incorporation of DP, Revision 3, into its license, by license amendment. Revision 3 of the DP details the active groundwater remediation plans that specifically target areas for groundwater                           ( print page 8308)                        remediation where the concentration of uranium in groundwater exceeds the NRC criterion in License Condition 27.b. for unrestricted release. In addition, this amendment also revises the license to authorize the possession of Technetium-99 (TC-99) as a contaminant in groundwater, and to distinguish between the possession limit for “in-process” Uranium-235 (U-235) and U-235 in packaged waste that complies with fissile exemption criteria. The license amendment also clarifies the authorized place of use to include subsurface areas where the groundwater exceeds the NRC criterion, and areas where such licensed material will be transported or managed.                

                    After receiving the application, the NRC published a notice of opportunity to request a hearing and to petition for leave to intervene, and in accordance with section 20.1405 of title 10 of the                     *Code of Federal Regulations*                     (10 CFR), requested comments (88 FR 33932). No comments or request for a hearing were submitted. Prior to issuing the amendment (ADAMS Package Accession No. ML24339A701), the NRC performed a review of the application with the determination documented in the Safety Evaluation Report (SER) (ADAMS Accession No. ML24264A155). The NRC also issued an environmental review of the application and published a                     **Federal Register**                     notice of the Environmental Assessment and Finding of No Significant Impact (89 FR 103880).                

Upon completing its review of the application, the staff determined the request complies with the standards and requirements of the Atomic Energy Act of 1954, as amended, as well as the NRC's rules and regulations. The NRC approved and issued Amendment 22 to SNM-928, held by CERT to incorporate the DP, Revision 3, into the CERT license. Pursuant to 10 CFR 2.106(a)(1), the NRC is providing notice of the action taken. Amendment 22 was effective as of the date of issuance, December 22, 2024.

Dated: January 23, 2025.
