If so, the NRC has determined that the monitoring and surveillance activities that Part 50 licensees are conducting as part of existing as low as is reasonably achievable (ALARA) and radiological and environmental monitoring program activities, and the Nuclear Energy Institute (NEI) Ground Water Protection Initiative (NEI 07-07), meet or exceed the requirements of 10 CFR 20.1501(a). Therefore, the DPR does not impose any additional survey or monitoring requirements on these licensees. The DPR does require that Part 50 nuclear power plant licensees record the results of the existing monitoring and sampling programs in their 10 CFR 50.75(g) files, either directly or by reference. 10 CFR 50.75(f)(3) requires a preliminary decommissioning cost estimate, which includes an up-to-date assessment of the major factors that could affect the cost to decommission. Section 50.82(a)(9)(ii)(F) requires an updated site- specific estimate of remaining decommissioning costs. The results of the monitoring and sampling should be included in these estimates. If the answer to the second question is no (the licensee is not licensed under Part 50), proceed to Figure 2 to determine the next actions. Appendix A-1 to DG-4014, Page A-1-3 Discussion of Figure 2. Does the DPR really require me to do something? For purposes of the DPR, the NRC is using the requirement for financial assurance as a surrogate for the amount of material a licensee is authorized to possess. NRC regulations at 10 CFR 30.35, 40.36, and 70.25, each entitled “Financial Assurance and Recordkeeping for Decommissioning,” require some licensees to set aside funds devoted to decommissioning the site at the time of license termination. The amount of funds is a function of how much radiological material the licensee is authorized to possess. Licensees can meet the financial assurance requirements either by the methods specified in those regulations, or by a site-specific estimate. If a licensee’s possession limit does not
