ulatory guide provides a risk-informed, graded approach to implementing the regulation. The risk-informed approach to implementing this rule is illustrated in Figures 1–3. A more detailed discussion of each block of the figures is in Appendix A to this guide. Figure 1 illustrates the questions to determine if a licensee needs to do anything because of the DPR. As stated above, uranium recovery licensees are exempt from all requirements of this rule. Staff has reviewed NEI’s Ground Water Protection Initiative (GPI) and compared it to the DPR requirements. Based on this review, staff concludes that Objective 1.1, characterize site geology and hydrogeology, Objective 1.2, identify system, components and work practices that have the capability to release contamination to the ground water, and Objective 1.3, establish an on-site ground water monitoring program to ensure timely detection of unplanned radiological releases to ground water, of the GPI establish a satisfactory framework for licensees to institute an effective ground water monitoring program as required by 10 CFR 20.1501(a). GPI Objective 1.4, establish a protocol to prevent off-site migration and minimize decommissioning impacts, provides an acceptable approach to the requirements of 10 CFR 20.1406(c). GPI Objective 1.5, ensure records of leaks and spills are retained in accordance with 10 CFR 50.75(g), is consistent with the recordkeeping requirements of 10 CFR 20.1501(b). Therefore, nuclear power plant licensees that have implemented NEI’s GPI are considered to have an adequate subsurface monitoring program as part of meeting the requirements of 10 CFR 20.1501(a), and a recordkeeping system in accordance with 10 CFR 20.1501(b). NRC reviewed Topical Report NEI 08-08, “Generic Final Safety Analysis Report Template Guidance for Life-Cycle Minimization of Contamination,” Revision 3. As documented in a letter to NEI dated October 19, 2009 (ADAMS Accession No. ML092720253), “The NRC staff finds that
