Oconee Nuclear Station Units 1,'2 & 3-Dockets Nos 50-269-270-287
Dear Dr Morris:
By letter of September 17 to Mr Harold Price, Governor Robert E McNair transmitted
'coments of the state agencies of South Carolina with regard to the environmental offects of our Oconee Nuclear Station. Governor McNair's letter urged the granting
'of our Operating License, l.
Attached to Governor McNair's letter is a copy of the September 9 letter of the I
South Carolina Pollution Control Authority which included three questions in connection with page 3 of our report " Environmental quality Features of Duke Power l
Company's Keowee-Toxaway Project." These questions are as follows:
t "Page 3 of the report states no adverse effects on the ecology have been detected due to temperature rises.
(a)
What do they mean by adverse effects?
(b). What happened to the number of species of micro-organisms due to the increase in temperature? Did they increase or decrease?
- ( c) What happened to the number within the.npecies of micro-organisms?"
l l
l We are pleased to submit the following information in response to these questions:
)
I
.(a).Page.3 of-our report stated that the temperature rise through the Oconee condensers was consistent with temperature rises employed.on Duke's lakes since 1926,'"and no adverse effects on the ecology l.
have been detected." This statement was based on long-term empirical observations that there has been no evidences or even a single report, l
of any fish kills on'our lakes due to thermal discharges.

As a part of the Edison Electric Institute's Research Project #49,
' biological studies _are continuing on Lake. Norman in the' vicinity of Lour. Marshall Steam Station which has been in service since 1965 with a skimmer wall similar to that provided for Oconee on Lake Keowee.- These studies are being managed by scientists at Johns Hopkins University with assistance from-local universities, state agencies and company personnel.
It can be generally stated.that studies of aquatic micro-organisms within the: waters of Lake Norman which are thermally influenced by the Marshall Station show that. planktonic populations.do not reveal significant redtc-tions in species, composition or diversity compared to control-stations outside the-thermal influence. 'As the detailed data from this program are assimulated and studied by the many participating.gro zps, reperts will be published that will speak more specifically' to the efiects on each species of micro-organism.
Copies of these reports will be furnist ed to the South Carolina Pollution Control Authority as soon as available.
We have discussed this information with representatives of the South Carolina Pollution L
Control Authority, and they advise that this is a satisfactory response to their questions.
-Yours very truly, l
