Dear Mr. D.ent6n:

. PROPOSED 'TECHNICAL. SPECIF I CAT I ON.* CHANGE: NO~: 73 In our letter of March 15, 1979, Serial No. 411D/07107B, we had re-quested proposed TechnJcal Specification Change Noe 73 which addressed the new radiological effluent technical specifi~ation guidelines as requested by Mre Grimes* in his letter of July 11, 1978.
It was noted in our letter that certain setpoints in Table 3.7~5 were still under development by our technical staff and would be submitted at a later date. These setpoints have been developed; however, since the guidelines do not place the setpoints in the technical specifications, it is now our intent to include them in the Offsite Dose Calculation Manual where they would be more useful to the operating staffe The attached revision to our proposed Table 3.7-5 should be substituted into our previous submittal.
Enc 1 osu re Very truly yours, C. M Stallings Vice President-Power Supply and Production Operations cc:
