Ms. E. G. Adensam, Chief Licensing Branch No. 4 Re: Catawba Nuclear Station Docket No. 50-413 Technical Specification

Dear Mr. Denton:

My letter of October 29, 1984 transmitted proposed amendments to the Catawba Technical Specifications.

In response to telephone conve~ 7tions between several members of your Staff and Mr. Roger Ouellette of Duke Power, attached is a revised pranosal in regard to my previous letter. The justifications and safety analysis remains unchanged from that previously submitted.

Very truly yours, Gdh a
