DEPARTMENT OF THE ARMY BALTIMORE DISTRICT. CORPS OP ENGINEERS P.O. BOX I 71 5 BALTIMORE. MARYLAND 21202 REPLY TO ATTKIITIOIIOFs NABPL-E 27 May 19.80 Mr. Donald E. Sells Acting Branch Chief Environmental Projects Branch 2 Division of Site Safety & Environmental Analysis U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Sells:

Our office has reviewed the Susquehanna Steam Electric Station, Units One and. Two, Draft Environmental Statement Draft Supplement, Conyngham Township of Luzerne County, Pennsylvania, in keeping with. this office's direct responsibility. This agency's areas of concern are flood control hazard potentials,,permit requirements under Section 404 of the Clean Water Act, and other direct and indirect impacts on Corps of Engineers existing and/or proposed projects. In accordance with these responsibilities, our office has the following comments:

a. The proposed dam is to be constructed in waters of the United States and is,, therefore, subject to the regulatory authority of this office. However, since the proposed dam is to be constructed above the headwaters of Pond Hill Creek, the work is authorized under the provisions of a Department of the Army Nationwide Permit. The attached 'sheet describes the conditions which must be satisfied for the purposes of Section 404 of the Clean Water Act, and the Management Practices which should be followed, to the maximum extent practicable, in the discharges of dredged or material to minimize the adverse effects of these discharges on the aquatic fill environment. The proposed intake structure is to extend approximately 30 meters into the Susquehanna River, a navigable water of the United States, therefore, an individual Department of the Army permit for the intake would be required in accordance with Section 10 of the River and Harbor Act.

b. As noted in 4.4.2.3, Hydrologic Design on Dam, page 4-11, the proposed spillway would be inadequate for passing the PMF using NRC criteria. Thus, a potential flood hazard would exist from failure of the dam due to overtopping. The document should address this flood hazard.

'. 'hNAGENER PRACTXCES I

':- 1 . Discharges of dredged or M1 material into waters of the United States

'..: should be avoided or minimized through the use of other practical alternatives-,f' 2 Discharges in spawning areas during spawning seasons should be avoIded ~ .

3. Discharges should not restrict or impede the movement of aquatic species

~ 'ndigenous to the waters ox the passage of normal or e~ected h gh flows or cause the relocation of the waters (unless the prImary purpose of the is to impound waters)g fill 4 ~ Xf t:he dischaige creates an impoundment of water, adverse icpacts on

- the aquatic system caused by the accelerated passage of water and/or the restriction of its flow, should be minimized;

5. Discharges on wetlands areas should be avoided;

6. Heavy equipment works in wetlands should be placed on mats;

7. Discharges into breeding and nesting areas for migratory waterfowl should be avoided; and

8. All temporary fills should be removed in their entirety.
