uld 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 prior NRC approval (The licensee’s 10 CFR 50.54(q) evaluation must document the basis of this equivalency conclusion). DG-1324, Page 29 (2) A planned change to relocate the EOF that impedes the principal OROs from participating in the response at the EOF would generally not require prior NRC approval provided that these organizations accept the availability of reliable telecommunications capabilities (e.g., videoconferencing, WebEOC™, or digital display boards connected via a data link) as viable alternatives. See Regulatory Position 2 for more information. 4.9 10 CFR 50.47(b)(9)—Emergency Assessment Capability a. The regulation at 10 CFR 50.47(b)(9) states the following: Adequate methods, systems, and equipment for assessing and monitoring actual or potential offsite consequences of a radiological emergency condition are in use. b. The following emergency planning function has been defined for this planning standard: Methods, systems, and equipment for assessment of radioactive releases are in use. c. Sections IV.B and IV.E.2 of Appendix E to 10 CFR Part 50 provide supporting requirements. Informing criteria appear in Section II.I of NUREG-0654 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 to assess imminent and ongoing radioactive releases in accordance with the emergency plan. Examples include the following: (a) a change that reduces the availability of meteorological data in ERFs where dose assessments are performed and PAR decisions are made; (b) a change in ERO staffing that would eliminate the onshift capability to make timely and accurate estimates of the actual or
