identified during site surveys. Licensees must ensure that the site-specific decommissioning cost estimate is greater than the minimum amount of decommissioning funds estimated to be required under 10 CFR 50.75(b) and (c), as reported to the NRC in accordance with 10 CFR 50.75(f)(1). The cost of remediating known radiological contamination must be included (e.g., soil, ground water, surface water). For decommissioning activities that delay completion of decommissioning by including a period of storage, the PSDAR must provide a discussion of a means of adjusting cost estimates and associated funding levels over the duration of the storage period to ensure that the appropriate amount of funding will be available in accordance with 10 CFR 50.82(a)(8)(iv) and 10 CFR 52.110(h)(4). Detailed guidance for the preparation and submittal of a site-specific decommissioning cost estimate can be found in RG 1.202, “Standard Format and Content of Decommissioning Cost Estimates for Nuclear Power Reactors.” 4. Environmental Impacts The regulations at 10 CFR 50.82(a)(4)(i) and 10 CFR 52.110(d)(1) require a licensee’s PSDAR to discuss whether the environmental impacts associated with site-specific decommissioning activities will be bounded by appropriate federally issued environmental review documents and describe any decommissioning activities whose environmental impacts will not be so bounded and will be evaluated prior to the performance of the activities. Specifically, before preparing the PSDAR, the licensee should evaluate the potential environmental impacts associated with the site-specific decommissioning activities, including those activities listed in Sections C.1 and C.2 of this guide. The potential environmental impacts associated with decommissioning should be evaluated against the impacts described in appropriate federally issued environmental review documents, as described previously. The comparison to impacts in other appropriate federally issued environmental
