REVISION TO THE HYDROLOGIC ENGINEERING INPUT TO THE DRAFT ENVIRONMENTAL STATEMENT SUPPLEMENT POND HILL RESERVOIR EVALUATION SUSQUEHANNA STEAM ELECTRIC STATION UNITS 1 AND 2 DOCKET NUMBERS 50-387 AND 50-388 Replace the last two paragraphs of Section

4. - Hydrologic Impacts of Construction with the following:

Water will be conveyed between the inlet-outlet structure in the reservoir and the pumping plant at the Susquehanna River, via pipeline.

The pipeline will be buried and will run parallel to the lower reach of Pond Hill Creek from downstream ot'he dam to the pumping plant.

Just below the dam a branch of main pipeline will run to the stream.

This will be used to divert natural streamflow during the construction of the dam and later, as described in Section 4.3.2,.to supply conservation flow to the stream.

The proposed location of the piimping station is adjacent to the railroad in an area outside-the 1 percent chance (100-year) floodplain as shown in figure (figure 11F of December 17, 1979 submittal).

Pipelines connecting the pumping plant to the submerged intake and discharge will be buried in the floodplain, The applicant has stated that after completion of e

'onstruction the land surface in the floodplain will be restored.

We

'I conclude that there is no practicable alternative to the construction in the floodplain of this section of pipeline and that the hydrologic impacts would be minimal.
