at the time of license termination, licensees should estimate the financial impact and consider timely remediation. Licensees should judiciously monitor the area until concentrations are decreasing to ensure that the corrective action has been effective. The revised 10 CFR 20.1501(b) also requires licensees to record, in records important to decommissioning, the amounts and locations of subsurface residual radioactivity that may need remediation at the time of license termination. These records provide important input to the historical site assessment. At 10 CFR 30.35(e), 40.36(d), 70.25(e), and 72.30(b), the DPR also requires licensees to adjust decommissioning funding as appropriate to the license type. Nuclear power plant licensees should include the effect of survey results in the decommissioning cost estimates required by 10 CFR 50.75(f)(3) and 10 CFR 50.82(a)(8)(iii). Other licensees should adjust decommissioning trust funds to reflect the necessary remediation to meet unrestricted use criteria at the time of license termination. See NUREG-1757, Volume 3, Revision 1, for additional information (Ref. 8). DG-4014, Page 10 Figure 3a What does the DPR require me to do? DG-4014, Page 11 Figure 3b What else does the DPR require? DG-4014, Page 12 C. STAFF REGULATORY GUIDANCE 1. Power plant licensees that have implemented the “Industry Ground Water Protection Initiative— Final Guidance Document (NEI 07-07) are considered to have implemented an adequate subsurface monitoring program for residual radioactivity in and around the facility. Thus, nuclear power plant licensees under 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities” and those that operate under 10 CFR 52.103, “Operation under a combined license,” that have implemented 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
