ATTN:
Dr. James Coughlin Senior Vice President P. 0, Box 3100 Hiami, Plorida 33101 Gentlemen:
In reference to your letter of tfny 4, 1973, requesting confirmation of your interpretation of paragraph 3.C (1) of Pacility Operating License No. DPR-41, we are in agreement with your interpxetation as set forth in your letter.
However, wc wish to make some additional clarifying comments'aragraph 3.C.(1) of License Ho. DPR&1 for Turkey Point Unit 4 is taken verbatim fxom paragraph 7.c of the Summary and Conclusions of the Pinal Environmental Statement on Turkey Point Units 3 and 4, issued July 18, 1972.
The same requirement is referenced in paragraph 4 of License Ho DPR-31 for Tuxkey Point Unit 3, issued July 19, 1972.
The basis for the AEC Staff position was summarized in the last paragraph of the Pinal Environmental Statement (page X-21), which reads as follows:
"On balance, it is concluded at this tfme that the Appli-cant's existing plant design is an acceptable proposal for providing the needed power Although there are alternative cooling systems which may be competitive in costs and have the potential for less impact on the envi-
ronment, there are uncertainties at tMs time that these alternatives would be better than the Applicant's current design.
Continuing monitoring and study programs are to be carried out to evaluate further the environmental impact of the proposed action.
Studies axe also to be conducted on possible improvements of the proposed cooling system, including the once-through cooling systems described in thisSection X.
Results developed in the study programs are to be utilized in improving and modi-fying the operation of the plant and its cooling system so as to achieve a minimal environmental impact."

The AEC Staff has had some concern as to how well your proposed cooling canal system would w'ork, particularly with respect to avoiding excessive salinity levels during prolonged adverse operating conditions.
There had been some uncertaint ies regarding tidal effects on channe 1 flows and the manner of operation of the intake/discharge contro 1 s tructure so as to achieve the desired amount of purging of excess salinity.
The Staff felt there was a need for continued evaluation of environmental impacts that.
would result from once-through cooling alternatives.
In the event that the proposed "closed cycle" cooling syst'm would not prove to function as necessary to comply with applicable restrictions on plant operations and that other sat isfactory closed cycle alternatives would not be available on a timely basis so as to allow the Turkey Point Plant to be used to meet the acute need for power in the Plorida area, the additional s tudies would be needed to support any proposal for use of a once-through system as that action entailing the least adverse environmental impact.
Section 4.A.3 of Appendix B (Environmental Technical Specifications) of the Turkey Point Units 3 and 4 1icenses provides that the specif ic envi-ronmental monitoring and surveillance of effects on the marine environment from discharges from the present interim coo 1ing system are not required whQ.e there are no discharges from this sys tem.
This monitoring and surveQ3.ance program is extensive, and the AEC Staff agreed with your staff-that it was not needed at the present time while there were no discharges into Biscayne Bay or Card Sound However, this section 4.A.3 of Appendix B does not refer to paragraph.3.C. (1) of License No. DPR-41 or paragraph 4
of Licens e No. DPR-31 and the continuing studies of once-through cooling alternatives as referenced in those paragraphs. It is appropriate that these continuing studies of once-through cooling alternatives not be terminated until such time as the final cooling system has been established and confirmed to operate sat isfactorily.
Ve note the first Semi-Annual Environmental Monitoring Report submitted September 28, 1973, for Turkey Po&t Units 3 and 4 did not include a dis-cussion on the testing and operation of the cooling system as requested in our letter of August 29, 1973.
Re request the preliminary assessment of the cooling system expected to be available by December 1, 1973, be fur-nished to the AEC Staff as soon as possible (25 copies), rather than as part of the next Semi-Annual Environmental Monitoring Report, which is not due until March 1, 1974 ~
