7 LONG ISLAND LIGHTING COM PANY

_3m,,O fM SHOREHAM NUCLEAR POWER STATION fs P.O. BOX 618, NORTH COUNTRY ROAD + WADING RIVER N.Y.11792 March 19, 1979 SNRC-364 Mr. William H. Regan, Chief Environmental Projects Branch 3 Division of Site Safety and Environmental Analysis U

S Nuclear Regulatory Commission W

tgton, D. C.

20555 Shoreham Nuclear Power Station - Unit #1 Docket No. 50-322

Dear Mr. Regan:

In accordance with the Shoreham preoperational monitoring program for aquatic ecology as outlined in LILCO letter dated September 22, 1976 (SNRC-127 ) and revised in LILCO letters of October 22, 1976 (SNRC-139 ) and December 29, 1976 (SNRC-152), LILCO has been collecting samples from Long Island Sound in the vicinity of the Shoreham Site and the Wading River.

Based on our analysis of the data collected, we propose that effective with the first 1979 quarterly sampling period, the Wading River fish and benthos portion of the sampling program be discontinued.

We presently have two years (1977 and 1978) of Wading River fish and benthos data collected.

The first six quarterly samples for water quality, benthos and fisheries data have been analyzed and are enclosed herein for your use.

This data has been summarized for the period of March 1977 through June 1978.

The analyses of the two samples from the second half of 1978 will be available in about four to six weeks.

Copies of the Analysis can be forwarded upon request.

From the enclosed data, it can be determined that the Wading River is not a unique or unusual ecosystem; that is, it does not provide a habitat for any rare invertebrate species nor serve as at-important nursery or spawning area for finfisa.

Therefore, we conclude that no useful purpose would be served by the continued aquatic monitoring of Wading River.

However, the annual vegetational monitoring program will be continued in both the Wading River marsh and the western marsh as described in the Shoreham Environmental Report and NUREG-0285, Final Environmental Statement, Section 6.2.4.

Regan March 19, 1979 Re:

Shoreham Preoperational Monitoring Page 2 Program for Aquatic Ecology We request your concurrence with the above described modification to the pre-operational monitoring program that no further aquatic sampling be conducted in the Wading River.

. Sediment Mean sediment particle size diameter was cuite variable from one season to the next.

This is attributable to the rapidly changing topography of the marsh over short distances.

Conclusion Tidal and seasonal affects are major influences in determining species composition in Wading River.

Since the creek is relatively shallow physical factors such as tidal flow, air temperature and fresh water runoff play important roles in creating an environment of gradients and rapid change.

Organisms observed in this environment demonstrate distributions represented by gradients and patchiness.
