Dear Mr. Grier:
Pursuant to Connecticut Yankee Environmental Technical Specifications (ETS).
Section 3.1.1.3, Connecticut Yankee Atomic Power Company hereby forwards the following report regarding fish impingement overruns.
An estimated 701 and 1178 Common Shiners (NOTROPIS CORNUTIS) O to 3",
and 3" to 6" length categories respectively, were impinged as of March 29, 1978 thereby exceeding the monthly limits of 100 for the 0 - 3" class, and 120 for the 3" to 6" class as set forth in Environmental Technical Specifica-tions, Table 3.3-1.
There was no apparent cause for these occurrences which could be related to changes in plant operations.
The common shiner, described in the literature as a small, schooling-type fish of the minnow family, has been impinged almost exclusively during the winter season.
It is felt that a combination of factors--seasonal temperatures encountered during this time of year, and a highly fluctuating year class size, help contribute towards increased impingement.
Very truly yours,
"[
