PWR fl APPLICANTS RESPONSE DATE NECESSART FOR NEIT ACTION PLANNED ON PROJECT:
As soon as possible REVIEW STATUS:
Awaiting information Comments from EPA dated August 16 on the draft environmental stacament for Three Mile Island indicate that a large pump storage proj ec t is to be constructed on Stony Creek upstream of the site.
The applicant has nowhere, to our knowledge, described this project in his application although it potentially could have significant implications on the adequacy of his design bases for flood protection.
As we have discussed the applicant of our concern,about should be promptly notified the potential safety implications, the deficiency of his application in this important area, and the probable extension of review schedules.
The type of information we will need to evaluate the safety implications are given in the enclosure.

HYDROLOGIC ENGINEERING CONCERNS THREE MILE ISLMO DOCKET N0. 50-289 & 50-320 It has ccme to our attention that a large pu=p storage facility is propcsed for construction on Stoney Creek, upstream of the Three Mile Island site. Provide the follcwing infor=ation, in sufficient detail to allow an independent review to be made, to assure that this proposed facility will not adversely affect tne plant:
- 1) Provide sufficient information to a) assure that the pro-posed pu=p storage plant can adequately pass its local pro able maximum flood; b) adequately pass the basin probable maximum flood; or c) in the event that cases a) or b) cannot be satisfied, that '.he effects of the failure of the facility during such floods will not adversely affect the Three Mile Island site.
- 2) Provide assurance that the proposed facility can adequately sustain its local safe shutdown earthquake.
In the event that such a conclusien can be furnished, postulate the arbitrary oeismically induced failure cf the structure and analytically demonstrate that the resulting flood wave will not adversely affect the Three Mile Island site.
3)
In the event that the situatiens described in 1) and 2) above cannot be satisfied, that is that it cannot be shown that the Three Mile Is:and site can safely withstand the

_2 effects caused by the inability of the proposed Stoney Creek pump storage facility to withstand the s3:e level of natural phenomena severity suggested for nuclear power plants, describe hcw you intend to provide adequate flood problems for the Three Mile Island site for such conditions.
