Dear Daniel Stoddard:

The U.S. Nuclear Regulatory Commission (NRC) identified an error in the documentation of the Emergency Preparedness Biennial Exercise Inspection Report 05000336/2022501 and 05000423/2022501, dated November 21, 2022 (ADAMS Accession No. ML22325A104).

This report omitted the Performance Indicator samples completed using Inspection Procedure 711151 during the onsite inspection week. As a result, the NRC has reissued the report in its entirety to correct the error.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely, Daniel L. Digitally signed by Daniel L.
