In any case, all elements of the emergency preparedness program must be reviewed at least once every 24 months. General Background RG 1.101, Revision 3, issued August 1992 (Ref. 16), endorsed: • Nuclear Management and Resources Council (NUMARC)/National Environmental Studies Project (NESP)-007, Revision 2, “Methodology for Development of Emergency Action Levels,” issued January 1992 (Ref. 17). RG 1.101, Revision 4, issued July 2003 (Ref. 18), endorsed: • NEI 99-01, Revision 4, “Methodology for Development of Emergency Action Levels,” issued January 2003 (Ref. 19), as acceptable methods for licensees to consider in the development of their plant-specific EAL schemes. RG 1.101, Revision 5, issued June 2005 (Ref. 20), provided: • Guidance for co-located licensees on conducting emergency response planning activities and interactions in the years between participation in offsite full- or partial-participation exercises. RG 1.101, Revision 6, issued June 2021 (Ref. 21), captured prior endorsement of two NEI guidance documents: DG-1423, Page 6 • NEI 99-01, Revision 5, “Methodology for Development of Emergency Action Levels,” February 2008 (Ref. 22), which the staff found acceptable for use by licensees and applicants as a methodology to develop or upgrade EAL schemes in accordance with related sections of Appendix E to 10 CFR Part 50. In addition to clarifying certain sections of previous revisions, Revision 5 of NEI 99-01 formalizes enhancements to emergency planning associated with hostile action events for emergency preparedness programs. The NRC endorsed this guidance in a memorandum to NEI, “U.S. Nuclear Regulatory Commission Review and Endorsement of NEI 99-01, Revision 5,” February 22, 2008 (Ref. 23). • NEI 99-01, Revision 6,
