rgency response are provided and maintained. b. Two emergency planning functions have been defined for this planning standard: (1) Adequate facilities are maintained to support emergency response. (2) Adequate equipment is maintained to support emergency response. c. Sections IV.E.1–4, IV.E.8, and IV.G of Appendix E to 10 CFR Part 50 supply supporting requirements. Informing criteria appear in Section II.H of NUREG-0654; NUREG-0696, “Functional Criteria for Emergency Response Facilities,” issued February 1981 (Ref. 16); and the licensee’s emergency plan. The following are examples of changes to the licensee’s emergency plan that could require prior NRC approval: (1) A change could require prior NRC approval if it would reduce the capability of the ERO in the TSC, EOF, or OSC to perform assigned functions and tasks in accordance with the emergency plan. Examples include the following: (a) a reduction in the existing reliability or redundancy of data acquisition, display, and analysis equipment supplied in the ERFs; (b) a relocation of an EOF that makes it infeasible for State or local ORO personnel to respond to, and participate in, the EOF as they currently do without adequate compensatory measures; (c) a permanent substitution of personal protective equipment for installed engineered habitability features; (d) a reduction in the frequency of ERF equipment maintenance, calibration, or testing that is not supported by the site’s experience with equipment reliability (e.g., a frequency greater than the observed mean time between failures); (e) a change to an ERF use that allows nonemergency uses that would decrease the readiness of the ERF for emergency use; and (f) a change that reduces the inventory or availability of equipment. d. The following examples would generally not require prior NRC approval: (1) A change that replaces existing ERF equipment with equipment of like quality, reliability, performance, and user interface would generally not require
