the requirements in Appendix E to 10 CFR Part 50. The NRC may approve, deny, or return, as appropriate, the license amendment application in accordance with 10 CFR 50.91, “Notice for Public Comment; State Consultation,” and 10 CFR 50.92, “Issuance of Amendment.” b. If the change is such that any planning standard in 10 CFR 50.47(b) or any requirement in Appendix E to 10 CFR Part 50 is not met, the licensee will need to request an exemption from the affected requirements in accordance with 10 CFR 50.12.

The regulation at 10 CFR 50.54(q)(6) requires the licensee to retain the emergency plan and each change for which it obtained prior NRC approval under 10 CFR 50.54(q)(4) as a record until the Commission terminates the license for the nuclear power reactor. Although the licensee is not
