.g Dear Mr. Price This is in respense to Mr. Boyd's letter transmitting for our cements copies of materials related to the applicatice by the Duke Power i
capany for an operating license for the Ocmee Nuclear Station, Units 1, 2, and 3, Oconee County, south Carnlina, AEC Docket Nos.g-50-270, and 50-287. We have reviewed the Final Safety Analysis Report, including its emendments, the company's draft envirt-antal statement dated July 1(JTO, and the comany's letter of October 30, supplementing the statement. As a part of this review the c e ments of the Center for Estuarine and Manhaden Research,nw a part of the National Marine Fisheries Service of the Department of Ccmerce, were obtained and are included herein.
The station site is adjacent to the company's Keowse Dam and Hydro-electric Station now under construction en the Keowee River just up-streen from the existing federally-owned Hartvell Reservoir. Each unit of the n= lame statim will use a pressurized water reactor with an output of about 2,584 MWt (886 MKe). A radicactive waste disposal system, fuel handling system, a=414 *v skwi,urus, and other onsite facilities required for a emplete and operable nuclear powerplant would be provided. Constructica permits for all three units were issued by the AEC on Noved er 6, 1967. Ccamercial operation is scheduled for Unit 1 in May 1971; Unit 2 in May 19721 and Unit 3 in June 1973 About 4,740 c.f.s. of water would be conveyed to the station fram the Little River arm of Iake Keovee through an intake conduit to the station to cool the enndensers of al'. three units. Nomal celing water discharges would be into the Kawee River am of Lake Keovee about 3,700 feet frcus the hydroelectric station intake. Emergency dis-charge of amiing waters and normal discharge of liquid affluent from the waste treatment facilities would be into the Keowee Dam tailrace at the headwaters of Hartwell Reservoir.
Fishery resources of Hartwell Reservoir include largemouth bass, erappies, carp, and suckers. In addition, striped bass and wallaye 1

have been stocked in the reservoir and trout in the tailwater area.
These resources.upywt moderate sport fishing and a minor ccessercial fishery. Lake Keowee will support fishery resources very similme to i
those of Hartwell Reservoir, and will provide additional sport fish-ing opportunity in this area.
Thecompanyindicatesthat(1)studiesofthethermaleffectsofthe j
Oconee station will be included in its or4oing monitoring program to determine the impact on the aquatic resources and the environitent, i
i (2) the condenser tubes will be cleaned by mechanical means without using chemicals. (3) the radioactive vastes will be released in con-centrations as low as practicable and below the allowable limits, (h) the velocity of the water entering the statica intake stzsacture vill be low enough to prevent a significant loss of fish through the structure into the plant, and (5) pre-operational enviromental radio-logical monitoring studies will be continued and similar studies will be ecsitinued after plant operation.
i I
i We are concerned that the thermal and radiological effluents may cause significant damage to fish life and the aquatic envirwo.aat, and that a significant number of fish may be lost into the intake structure and destrcyed. If the surveys establish that the heated or radioactive effluents discharged into Lake Keowee and its tailrace result in e.hanges in Lake Keowee, its tailrace, or Hartwell Reservoir that are significantly detrimental to the fish and wildlife resources
}
or the environment, corrective measures should be taken to reduce the i
temperature and the radionuclide content of the affluent. Should the studies show that significant numbers of fish are withdrawn with the cooling water, suitable fish protective devices should be installed at the intake structure to reduce the d-admr effects to within i
acceptable limits.
I In view of the importance of the sport fishery in Hartwell Reservoir i
l and the fishery potential of Lake Knowee, it is imperative that every effort be made to protect these valuable resource fram possible d=7 j

Dear Mr. Price:
This is in response to Mr. Boyd's letter transmitting for our co=ments copies of materials related to the applicatien by the Duke Power Ccmpany for an operating license for the Cconee nuclear Statien, Units 1, 2, and 3, Oconee County, South Carolina, AEC Docket Nos. 50-269, 50-270, and 50-287 We have reviewed the Final Safety Analysis Report, including its amendments, the ca.npany's draft environmental statement dated July 1970, and the company's letter of October 30, supplementing the stt ~ ecent. As a part of this review the cecments of the Center for Estuarine and Menhaden Research,now a part of the National Marine Fisheries Serrice of the Department of Commerce, were obtained and are included herein.
The station site is adjacent to the company's Keewee Dam and Hydro-electric Station now under construction on the Keowee River just up-stream froa the existing federally-cwned Hartwell Resertoir. Each unit of the nuclear statien will use a pressuri::ed water reactor with an output of about 2,584 MWt (886 !Ge). A radioactive waste disposal system, fuel handling system, auxiliary structures, and other onsite facilities required for a complete and operable nuclear powerplant would be provided. Construction pemits for all three units were issued by the AEC on Novecber 6, 1967 Ca:nercial operation is scheduled for Unit 1 in May 1971; Unit 2 in May 1972; and Unit 3 in June 1973 About 4,740 c.f.s. of water would be conveyed to the station frcm the Little River am of Lake Keowee thrcugh an intake conduit to the station to cool the condensers of all three units. Nomal cooling water discharges would be into the Keowee River arm of Lake Keowee about 3,700 feet frem the hydroelectric station intake. Emergency dis-charge of cooling waters and normal discharge of liquid effluent from the vaste treatment facilities would be into the Keowee Dam tailrace at the headwaters of Hartwell Reservoir.

These resources support moderate sport fishing and a minor comercial fishery. Lake Keovee will support fishery resources vert similar to those of Hartwell Reservoir, and will provide additional sport fish-ing opportunity in this area.
The company indicates that (1) studies of the thermal effects of the Oconee station will be included in its ongoing monitoring program to determine the impact on the aquatic resources and the environment, (2) the condenser tubes will be cleaned by mechanical means without using chemicals, (3) the radioactive wastes will be released in con-centrations as low as practicable and below the allowable limits, (4) the velocity of the water entering the station intake structure will be low enough to prevent a significant loss of fish through the structure into the plant, and (5) pre-operational environmental radio-logical monitoring studies will be continued and similar studies will be continued after plant operation.
We are concerned that the themal and radiological effluents may cause significant damage to fish life and the aquatic envirennent, and that a significant number of fish =ay be lost into the intake structure and destroyed. If the surveys establish that the heated or radicactive effluents discharged into Lake Keowee and its tailrace result in changes in Lake Keovee, its tailrace, or Hartwell Reservoir that are significantly detrimental to the fish and wildlife resources or the environment, corrective measures should be taken to reduce the temperature and the radionuclide content of the effluent. Should the studies show that significant numbers of fish are withdrawn with the cooling water, suitable fish protective devices should be installed at the intake structure to reduce the damaging effects to within acceptable limits.
In view of the importance of the sport fisher / in Htrtwell Resertoir and the fisher / potential of Lake Keovee, it is imperative that everf effort be made to protect these valuable resource from possible da= age from radioactive contamination, heated water, and losses into the intake structure. Therefore, we recomend that the Ccmmissien require the company to:
