Mr. Victor Stello, Jr., Director Division of Operating Reactors U.S. Nuclear Regulatory Commission Washington, DC 20555

Dear Mr. Stello:

Enclosed for your information are TVA's report concerning environmental effects of the plant intake at Browns Ferry Nuclear Plant and a copy of H. G. Moore's February 13, 19?8, letter to John C. White transmitting the report to EPA.

The report consists of the four volumes listed below:

Volume 1 Summary of the Evaluation of the Browns Ferry Nuclear Plant Intake Structure Volume 2 Analysis of Flow Patterns in the Vicinity of Browns Ferry Nuclear Plant Intake Volume 3 Evaluation of Plankton Entrainment by the Intake of Browns Ferry Nuclear Plant Volume 4 - Effects of the Browns Ferry Nuclear Plant Cooling Water Intake on the Fish Populations of Wheeler Reservoir As indicated by evaluations presented in Volumes 3 and 4, no significant impingement and entrainment are occurring.

These evaluations demonstrate no significant environmental impact on Wheeler.Reservoir because of the Browns Ferry Nuclear Plant intake structure.

Fish entrainment estimates were not as definitive as other biological parameters measured.

For this reason, we are continuing a further year of study to better define the fish entrainment and effect of the Browns Ferry Nuclear Plant intake on the fisheries resource of Wheeler Reservoir.

From the evaluations presented in this report, we believe that no modifications to the intake at Browns Ferry are required.

Very truly yours, J.

Dear iYir. Nhite:

He:

Browns larry Nuclear Plant iiPDES Permit No, AL0022080 Zn. accordance with Part ZZZ. E. and. Part Z.B.l.b. of the above-refcxonccd. permit, enclosed are docs cnts which constitute TVA's report related. to environmental e fects of the plant intake~

The rcpoxt consists of four volumes as follows:

Volume 1, Summary of'he Evaluation of the Browns I'erry Nuclear Plant Znta~zc Structure Vo3.ume 2, Pwa3.ysis of 71crr Patterns in the Vicinity of Browns Ferry Hucleax'lant Znta'~e Volume 3, Evaluation of PlarQ~von Entrainment by the Zntako of Browns Ferry Nuclear Plant Volume 4, Effects of the Browns I'erry Nuclear Plant Cooling

~Pater Znta'e on the Fish gopu3.ations of Mheeler Reservoir The evaluations contained. in Volumes 3 and 4 and. sxumarized, in Volume 1 of the report indicates that no significant iimiingement and cntraiwxnt are occuwing and. thu" no mod'fications are required.

as s~ecificd in P~ ZZl. E. of the pe."mit.

7fe believe that these evaluations demonstrate that the olant intake is not resultinc in a significant adverse environmental i~act to <Reeler Reservoir.

.or reason" indicated. in the report, quan~ification and. final assess-mcnt of fish entrain;cnt cannot be as definitive as the other biolog--

.cal assessments.

Thcrcforc, wc will continue for one year thc studies nccc"-ary to dcfin

-i"h cnt aim"=nt c"tinatcs and. to assess potential i=.:.'i.-,cs o" ~lant c-train;c."t on ~he iic':.e ies re"ourcc of ';ihec cr iicscrvoir.

'I Ne be1ieve that this report shows that no moiifications of'he Browns Perry intake are require4.
