'799 Roosevelt Road Glen Ellyn, Illinois 60137

Dear Mr. Keppler:

The Environmental Operating Report for the Donald C. Cook Nuclear Plant covering the period July through December 1976 was prepared and submitted to the NRC before analysis had been completed on a few remaining samples collected in late 1976 as part of the Environmental Radiation Monitoring Program.

This was noted in Section X., page 20, of the report.

~ Attached please find updated tables which include the results of the analysis of the remaining samples and replace those which appear in Appendix E to the report.

Very truly yours, RSH:mam Attachments (2)'
