RESPONSIBLE BRANC11 Environmental Projects Branch No. 2 PROJECT MANAGER: Hark Au DATE REQUEST RECEIVED: June 2, 1975 DESCRIPTION OF RESPONSE: ESB Comments on Proposed ETS Changes i
REVIEW STATUSt Environmental Specialista Branch Review Complete We hase reviewed the acceptability of the licensee's proposed Appendix B ETS changes for the Oconee Nuclear Station per your request (TAR No. 1635)
{
of June 2, 1975.
Duke Power's propoaed technical specification changes involve modifications in the following aspects of their current environ-mental monitoring programt (1) ETS 1.3.lA Water Quality I
I f
The proposed change consists of altering the depths of temperature, dissolved oxygen and biochemical oxygen demand measurements for l
enhanced compatibility with other program elements and specf *ying the depths in meters instead of feet.
i L.
(2) ETS 1.3.4 Phytoplankton-Zooplankton Receiving Water Studies The proposed change consists of substituting two fixed monitoring stations in the thermal plume in place of the present two stations which are located at the points where the surface temperature is 0.9 and 0.5 of the temperature excess of the discharge over ambient tenperature. It is claimed that it is extremely difficult to remain at the points where 0.9 and 0.5 temperature excesses over anbient surface temperature are located, i

(3) ETS 1.3.5 Benthos The proposed change cousists of referring to the Keowae River below Knowse Dam as Laka Hartwell and changing a single benthic sampling station - Station 605 to Station 606 It is claimed that it is m.

irpossibia to cample safely and effectively at Station 605 because of the compact nature of the bottom material and the periodic swift currents.
(4) ETS 1.6 Plume happing for Temperature and Dissolved Oxygen
)
The proposed change consists of deleting the requirement for sampling on a seasonal basis because the conditions during which a samplo is required are specified and the sampling will not be l
l strictly on a seasonal basis.
l i
Our review indicates that proposed changes (1) through (4) may be l
impicmented without decreasing the effectiveness of the pre.sent moni-toring program to detect environmental impacts from Oconee operation.
)
We recomnend that the licensea's proposed Appendix B ETS changes be
{
granted. Our review was conducted by John Bolen and John Lahr of the Environmental Specialists Branch.
