Informing criteria appear in Section II.A 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 authority and responsibility of persons filling key positions to perform their emergency assignments in accordance with the emergency plan. (2) A change could require prior NRC approval if it assigns major functional areas or major tasks to two or more onsite organizations simultaneously such that it would not be clear to ERO members and the OROs which organization has the authority and responsibility for the activity at any point in the response. An example of this type of change could be one in which the TSC and EOF would perform dose projection functions concurrently without assigned hierarchical responsibility. (3) A change could require prior NRC approval if it would reduce the licensee’s capability to staff key ERO positions identified in the plan on a 24/7 basis in accordance with the licensee’s fitness-for-duty requirements. d. Proposed changes to ERO names or titles would generally not require prior NRC approval if they do not change the functional relationships, authorities, competencies, or responsibilities for key positions identified in the plan. 4.2 10 CFR 50.47(b)(2) Onsite Emergency Organization a.
