INTRODUCTION I The objective of this monthly report is to document compliance with the nonradiological (aquatic) environmental monitoring programs specified in Sections 3.1.1.a(4) , 3.1.2.a. , and 4.6.1 of the Environmental Technical Specifications (ETS) . These programs have been carried out as directed in the Environmental Controls Aquatic Sampling Manual. Program elements being conducted under contract to GPU Nuclear Corporation include benthic macroinvertebrates, ichthyoplankton, fish population dynamics (seine and electrofishing), creel surveys, and water quality. The ultimate purpose of these studies is to obtain a database sufficient to establish the I natural fluctuations within the ecosystem and identify any significant biological alterations resulting from the TMINS.

Compliance with all programs specified in the ETS and detailed in the Aquatic Sampling Manual was achieved in March. Field work requirements described in the ETS and associated with the 1985 sampling season were completed as of 26 November. No collections were made during March.

Preparations were made for ce 1986 field sampling season. Routine main-tenance and repair of boats, sampling gear, and water quality instruments were completed. Pre-season instrument calibrations were completed, as were the 1986 TMINS Aquatic Sampling Schedules.

Data presented in this report are considered provisional, pending subse-quent proofing, analysis, and presentation in the annual report.

Weer Ounlity Au lvsis I objective: To measure select physical and chemical parameters of the Susquehanna River in the vicinity of Three Mile Island l Nuclear Station (TMINS) concurrent with General Ecological Survey samples.

l Progrens: The water quality section of the Annual Report was

~

completed and mailed to TMI-EC for editorial review.

I I Benthic Mac ro'i nver t eb r a t es I Obiactive: To assess the abundance, distribution, and diversity of benthic macroinvertebrates at three stations in the vicinity of TMINS.

i 5 Progress: Statistical testing of 1985 benthos data was

)

completed. The benthos chapter of the Annual Report was subsequently completed and mailed to TMI-EC for editorial review.

I Ic ht hvo ol ank t on I O jactive: To determine species composition, relative abundance, density, seasonal and spatial distribution of I ichthyoplankton at eight stations in the vicinity of TMINS.

Proerens: All ichthyoplankton 1985 summary runs were completed, as were tables, figures, and most statistical analyses. Writing of a first draf t of this chapter of the Annual Report was initiated.

I Obiective: To assess species composition, relative abundax ?.

seasonal and spatial distribution, condition f actor, occur-I rence of parasites, anomalies and fish kills, and species diversity of fishes vulnerable to seine capture at six stations in the vicinity of TMINS.

Proorena: Summary runs of all 1985 seine data were completed, as were all tables, figures, and statistical analyses. A draf t of this section of the Annual Report was completed and mailed to TMI-EC f or editorial review.

occurrence of parasites, anomalies, and species diversity of fishes vulnerable to electrofisher capture at six stations in  ;

the vicinity of TMINS.

I Progress: The first draf t of the electrofishicg chapter of the Annual Report. was mailed to THI-EC. Editorial comments were subsequently incorporated in a final draf t of this chapter. _.

i Ob j ec tive: To investigate the extent of success of sport- ,

fishing, and determine angler residence and use of catch, l l

in the Susquehanna River near TMINS.

I Proeress: All 1985 creel survey summary tables, figures, and statistical analyses were completed. A first draf t of this chapter of the Annual Report was completed and mailed to I

T211-EC.
