ented NEI 07-07 are presumed to be in compliance with the subsurface survey requirements of the DPR. Those licensees should ensure that the results of all surveys conducted per existing monitoring and surveillance programs, including NEI 07-07, that identify significant residual radioactivity are recorded, or incorporated by reference, in records important to decommissioning as specified in 10 CFR 50.75(g). Existing regulations at 10 CFR 50.75(f)(3) require that each power reactor licensee, at or about 5 years prior to the licensee’s projected end of operations, submit a preliminary decommissioning cost estimate. Licensees should include the results of the surveys in this estimate. The site-specific cost estimate required by 10 CFR 50.82(a)(8)(iii) should also include the costs of removing and disposing of significant residual radioactivity. Section 20.1501(b) does require that licensees document the results of the surveys in records important to decommissioning. NRC is not requiring licensees to submit reports of survey results. 2. For Part 30, 40, and 70 licensees, if the quantity of material authorized in the license is below the amount requiring financial assurance as specified in 10 CFR 30.35(d), 40.36(b) and 70.25(d), the DPR does not require any further action. The NRC presumes that such licensees will have minimal residual radioactivity resulting from operations, have current As Low As Reasonably Achievable (ALARA) and health and safety programs that are adequate to identify radioactivity requiring remediation, and will have funds from operating revenues to remediate the facility to unrestricted use criteria. 3. Staff experience (Ref. 9) shows that fluids are the primary source of contamination beyond facility equipment. If there are no fluid processes, the NRC presumes that licensees’ current ALARA and health and safety programs are adequate to identify radioactivity requiring remediation to meet unrestricted use criteria. The DPR requires action only
