Docket Nos. 50-269, -270, -287 W l
Dear Mr. Giambusso:
On February 13, 1975, eight of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected.
A total of 93,544 small fingerling fish, weighing 201 kilograms, had collected on the screens.
The fish, averaging 2.1 grams per fish, were removed from the screens and categorized, where possible, as to screen location, type, size, degree of decomposition, and weight.
This information is tabulated in Enclosure 1.
It is concluded that the mortality of these 201 kilograms of fish had an insignificant effect on fisheries resources in Lake Keowee.
Ve truly your
