Davis-Besse Nuclear Power Station Emergency Implementing Procedure Changes Ladies and Gentlemen:

In accordance with 10 CFR 50.4, this letter submits recent revisions of Davis-Besse Nuclear Power Station (DBNPS) Emergency Implementing Procedures RA-EP-01900, "General Emergency," and RA-EP-02620, "Emergency Dose Control and Potassium Iodide Distribution."

The changes, completed in accordance with 10 CFR 50.54(q), do not decrease the effectiveness of the Emergency Plan. The Emergency Plan continues to meet the requirements of 10 CFR 50.47(b) and 10 CFR 50, Appendix E. Therefore, as required by 10 CFR 50.54(q), DBNPS hereby submits the changes to Emergency Implementing Procedures RA-EP-01900 and RA-EP-02620.

If you have any questions, please contact Mr. Gregory A. Dunn, Manager - Regulatory Affairs, at (419) 321-8450.
