ws because of staffing changes. (3) A change could require prior NRC approval if it replaces an offsite radiological laboratory relied on in the emergency plan with a laboratory that does not have the capabilities or licenses that allow it to receive and analyze the radioactive samples anticipated in the emergency plan. d. A change to the EOF structure, organization, or location that would impede 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. 4.4 10 CFR 50.47(b)(4)—Emergency Classification System a. The regulation at 10 CFR 50.47(b)(4) states the following: A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures. b. The following emergency planning function has been defined for this planning standard: A standard scheme of emergency classification and action levels is in use. c. Sections IV.B and IV.C of Appendix E to 10 CFR Part 50 supply supporting requirements. Informing criteria appear in Section II.D of NUREG-0654 and the licensee’s emergency plan. d. When considering proposed changes associated with EALs, the licensee must consider the effect of the change on the accuracy of the classification and the timeliness of the classification. Section IV.C.2 of Appendix E to 10 CFR Part 50 requires the licensee to have the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of DG-1324, Page 23 indications that an EAL has been exceeded and to declare the
