Box 2178 PRODUCTION AND TRANSMISSION August 30, 1974 Mr. Angelo Giambusso Deputy Director for Reactor Projects Directorate of Licensing Office of Regulation U. S. Atomic Energy Commission Washington, D. C. 20545 Re: Oconee Nuclear Station Docket Nos. 50-269, -270,--287

Dear Mr. Giambusso:

On August 22, 1974, six of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 2,926 small fingerling fish,.weighing 15.5 pounds, had collected on the screens during the two-week interval August 8 to August 22. The fish, averaging 0.08 ounces 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 15.5 pounds of fish had an insignificant effect on fisheries resources in Lake Keowee.

Very truly yours, A. C. Thies ACT:vr Enclosure cc: Mr. H. J. Logan S. C. Wildlife & Marine Resources Dept. ,
