s to the decommissioning regulations in 1997 (62 FR 39091) (Ref. 14), 2003 (68 FR 19727) (Ref. 15), and 2014 (79 FR 66603) (Ref. 16). The 1996 rulemaking changed 10 CFR 50.82 to provide licensees with simplicity and flexibility in implementing the decommissioning process. The changes removed the requirement that the NRC approve a decommissioning plan before a licensee initiates the decommissioning process. The changes were also intended to clarify ambiguities in the previous decommissioning regulations, codify procedures and terminology that had been used in a number of specific cases, and increase opportunities for the public to learn about licensees’ decommissioning activities. The changes were designed to establish a level of NRC oversight commensurate with the level of safety concerns expected during decommissioning activities. In addition to the regulations in 10 CFR 50.82, on June 17, 2011, the NRC issued the Decommissioning Planning Rule (DPR) (76 FR 35512) (Ref. 17). The DPR requires all licensees to establish operational practices to minimize site radiological contamination and perform reasonable subsurface radiological surveys, and it also sets forth new financial assurance requirements that require DG-1349 Revision 1, Page 5 more detail in the site-specific decommissioning cost estimate submitted with the PSDAR than the estimates done in accordance with the financial assurance requirements of 10 CFR 50.75. The ultimate goal of the DPR is for licensees to have sufficient funds to conduct radiological decommissioning and thus, complete decommissioning effectively and efficiently. For any licensees that submitted a decommissioning plan before August 28, 1996, the NRC considers the decommissioning plan and the associated environmental review to be the PSDAR submittal. Decommissioning plans normally contain sufficient information to satisfy the requirements of the PSDAR. Licensees that have an approved decommissioning plan must submit an update for
