Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D. C. 20555-0001 Edwin 1.Hatch Nuclear Plant Fourth 10-Year Interval 1ST Program Update Ladies and Gentlemen:

By letter dated April 20, 2005 Southern Nuclear Operating Company (SNC) submitted Inservice Testing Relief Request RR-P-1. Subsequently, SNC discovered that the incorrect group designation had been shown for Residual Heat Removal (RHR) and Residual Heat Removal Service Water (RHRSW) pumps on pages 4 of 9 and 6 of 9 of RR-P-1. The only changes are RHR and RHRSW pumps being classified as Group A pumps instead of Group B pumps. The corrected pages are enclosed.

This letter contains no NRC commitments. If you have any questions, please advise.

Sincerely, H. L. Sumner, Jr.
