Oconee Nuclear Station
~
Docket Nos. ED-2693 -270, -287
Dear Mr. Giambusso:
Pursuant to 10 CFR 50.90, changes to the Oconee Nuclear Station Appendix B Technical Specifications, as shown on the attached replacement pages, are hereby requested. A summary of the proposed changes, and a justifi-cation for each, is presented below:
1 1.
It is requested that Specification 1.3.1.A, " Water Quality," be changed such that the temperature, dissolved oxygen and BOD sample depths are altered and are specified in meters rather than feet.
This will provide data which is more compatible with investigations initiated by Duke and other research groups.
In addition, the depths will be expressed in the presently accepted scientific units.
2.
It is requested that the sampling locations in Specification 1.3.4, "Phytoplankton-Zooplankton Receiving Water Studies," be changed.
Presently the geographical location of two points along the center-line of the Keowee River arm of Lake Keowee is determined each i
sampling period and represents the points at which the plume surface temperature is 0.9 and 0.5 of the temperature excess of the discharge over ambient surface temperature.
It is extremely difficult to remain at the poincs where the 0.9 and 0.5 temperature excesses over ambient surface temperature are located.
Fixed points will permit better comparison between thermally affected stations as well as facilitate sampling.
Data supporting this request is presented in the Oconee Nuclear Station Semiannual Reports for the periods ending June 30 and December 31, 1973 and June 30 and December 31, 1974.

iq Mr.'Angelo Giambusso Page 2 Mayl23,;1975 3.
It is requested.that Specification 1.3.5, " Benthos," be changed such that the Keowee River below the Keowee Dam be referred to as Lake Hartwell.
Also, a change of sampling stations from 605 to 606 is requested as it'is impossible to sample safely and effectively at 605 because of the very compact nature of the bottom material
'and the periodic swift currents. Data supporting this recommendation are presented in the Oconee Nuclear Station Semiannual. Reports for the periods ending June 30 and December 31, 1973 and June 30 and December 31, 1974.
4.
It is requested that Specification 1.6, " Plume Mapping for Temperature and Dissolved Oxygen" be changed'to delete the requirement for sampling on a seasonal basis.
The conditions during which a sample is required are specified and these studies will not be strictly on a seasonal basis.
Therefore, the reference to a " seasonal basis" is unnecessary.
The data required by Appendix B, Technical Specifications are reported on a semiannual basis.
It would be appropriate to make these changes at the beginning of the next reporting period.
Therefore, it is requested that you review and approve these proposed changes by July 1, 1975.
Very truly yours, Y M A. C.'Thies ACT:vr Attachment
