uate applications using a graded approach based on site-specific consequence analyses. Program elements that may be implemented and evaluated according to a graded approach include periodicity between inspections, drills, exercises, number of performance objectives, and staffing. a. Maintenance of Performance (10 CFR 50.160(b)(1)(i)) (1) The emergency plan should include a general description of the facility, any site-specific definitions, and any relevant appendices, drawings, diagrams, and other information needed to demonstrate compliance with this section. (2) The emergency plan should describe the process for maintaining and making changes to the emergency plan and associated procedures, including methods to account for facility changes and the methods used to conduct independent review of the EP program. Licensees may make changes to capabilities described in the emergency plan without creating a reduction in effectiveness, consistent with the requirements in 10 CFR 50.54(q), so long as emergency response performance does not decrease due to the changes in the capabilities. b. Performance Objectives (10 CFR 50.160(b)(1)(ii)) The emergency plan should describe a performance monitoring program to include the following topics: (1) The process used to develop performance metrics and objectives for each emergency response function in 10 CFR 50.160(b)(1)(iii), including the methodology used to develop the objectives, the basis for relying on the objectives, and how acceptability or successful achievement is determined; DG-1350, Page 11 For example, the methodology used to develop performance objectives and metrics could be: ݌݁ݎ݂݋ݎ݉ܽ݊ܿ݁ ݋ܾ݆݁ܿݐ݅ݒ݁ ݉݁ݐݎ݅ܿ (%) = ܰݑܾ݉݁ݎ ݋݂ ܿ݋ݎݎ݁ܿݐ ݋݌݌݋ݎݐݑ݊݅ݐ݅݁ݏ ܰݑܾ݉݁ݎ ݋݂ ݋݌݌݋ݎݐݑ݊݅ݐ݅݁ݏ × 100 (2) performance measures used during drills and exercises to determine acceptable performance, including the means for determining quality and timeliness; (3) reference levels
