Re: Docket No. 07000925; License No. SNM-928 Cimarron Environmental Response Trust Corrected Decommissioning Cost Estimate

Dear Recipients:

Solely as Trustee for the Cimarron Environmental Response Trust (CERT), Environmental Properties Management LLC (EPM) submits herein a corrected version of the updated decommissioning cost estimate (DCE) for the decommissioning of the Cimarron site. Facility Decommissioning Plan - Rev 3 (the D-Plan, accession number ML22287A079) included a DCE in Table 16-5.

EPM had submitted an updated DCE to the U. S. Nuclear Regulatory Commission (NRC) and the Oklahoma Department of Environmental Quality (DEQ) in a letter dated April 24, 2024 (ML24116A171). Attachment 1 to that letter presented a revised version of Tables 16-5a and 16-5b.

When reviewing the updated DCE, DEQ personnel noticed that the Total Annual Costs in Table 16-5a did not equal the sum of the component (i.e., License Compliance, Decommissioning, DEQ fees, etc.) costs.

Fortunately, Table 16-5b calculated the escalated annual cost for each component in Table 16-5a, not the Total Annual Cost in Table 16-5a. Consequently, all of the annual costs and the Year-End Available Funds presented in Table 16-5b were correct.

EPM encloses herein a corrected revision of the updated DCE presented in Tables 16-5a and 16-5b. Because Table 16-5b is unchanged from the April 24 submittal, this revised DCE still indicates that sufficient funding is available to achieve the NRC Criterion for groundwater.

Please note that the cost for construction represent approximately one-third of the available funds in this DCE, and that optimization of groundwater extraction and treated water injection rates provide opportunity to shorten the projected duration of remediation.
