Dear Mr. Keppler:

In compliance with Section 4.2 of App (ndix B to License No. NPF-3 for Davis-Besse Nuclear Power Station Unit No. 1 Technical Specifications, the Toledo Edison Ccmpany began a fish Impingement Study to investigate the number and species of fish which are impinged on the traveling screens of the power plant. This study was to be divided into three phases. Phase I currently in progress, is being " conducted for the first year of commercial operation to determine if the fish being impinged.

.< as a result of unit operation, are of significant number and value to adversely affect the fish population in the vicinity of the site and the lake as a whole".

The enclosed letter from Jeff Reutter, Ohio State University Center for Lake Erie Area Research, contains :he required decision criteria for determining whether to proceed from Phase I to Phase II. If you wish to further discuss these decision criteria, please contact Jennif er Scott-Wasilk (419) 259-5185 of our Environmental Activities Department.

Yours truly, , _. ~ ~ ~ ~

SUBJECT:

Criteria for Evaluating Fish Impincement As you know, determination of the level at which impingement would have a significant impact on fish p]pulations within the lake is near impossible.

Consequently, regulations which attempt to specify such an acceptable level generally do so with a l?rge margin of safety, and this is what' I propose for Davis-Besse.

Population estimates for most species within the lake are non-existant.

Howefer, the Ohic Division of Wildlife, through its annual publication " Status of Ohio's Lake Erie Fisheries" does present the commercial and sport harvests of fish from the Ohio waters of the lake during the previous year. Further-more, these sport and commercial catches are maintained at an acceptable level by the Division of Wildlife through the use of quotas, bag limits, closed seasons, etc. Results indicate that the species of major importance to these two groups of fishermen are: yellow perch (Perca flavescens), wall-eye /sauger (Sti:ostedion v. vitreun / Stizostedion canadense), white bass (Morone chrysops), freshwater drum ( Aplodinotus grunniens), channel catfish (Ictalurus punctatus), and smallmouth bass (Micropterus dolomieui).

As stated above, determination of the point at which greater impingement would be detrimental to the populations of these species is extremely diffi-cult and speculative. However, it is possible to select an acceptable level, and in this ragard I prcpose that if the impingement total for these 6 species combined at Cavts-Besse is less than 0.5% of the number or weight of all 6 species comoined collected by sport and commercial fishermen (Ohio waters only), then impingement losses at Davis-Besse are not having a signi-ficant impact on lake populations and, therefore, are at an acceptable level.

If inpingement is fcund to be at an acceptable level, then initiation of Phases II and III ' Sections 4.2.2 and 4.2.3 of the " Environmental Technical Specifications") is unnecessary.
