INTRODUCTION The ecology of York Haven Pond near the Three Mile Island Nuclear Station (TMINS) has been under investigation since February 1974, Studies initiated in April 1974 include analysis of ambient water quality, ichthyoplankton (far-field), ichthyoplankton entrainment, cacroinvertebrates, fish population dynamics, impingement of fishes, creel survey, and therral plume mapping.

This report discusses the progress of investigations conducted in December 1979.

2 COMPLIANCE WITH ENVIRONMENTAL TECHNICAL SPECIFICATIONS (ETS)

Objective: To determine compliance with the nonradiological (aquatic) environmental monitoring programs specified in sections 3.1.1. a. (4), 3.1. 2. a, 4. 2, and 4.6.1 of the ETS and to insure that said programs are performed as detailed in the Generation Procedures Manual.

Progress: Compliance with all programs specified in the ETS and detailed in the Generation Procedures Manual was achieved in December (Table 1), except for creel ;urvey. The third creel survey period (1700-2100 h) was not conducted throughout December at the East Dam, West Dam, and General Reservoir areas due to darkness.

During the week of 16 December ice conditions on York Haven Pond prevented sampling from boats. Only the creel survey and impingement programs scheduled for that week were performed. All other programs were rescheduled and performed during the week of 23 December. The creel survey scheduled for 21 December was only conducted at the York Ihven Generating Station.

A program by program summary of the progress for December follows.

MACR 0 INVERTEBRATES Objective: To describe the diversity and distribution of the benthic macroinvertebrates occurring at the five benthos sampling stations near TMINS.

Progress: Replicate (4) benthos samples were taken on 3 and 27 December (Table 1).

Enumeration, determination of dry weights, and identification of the macroinvertebrates have been completed through 27 December.

2370 258

3 ICHTHYOPU_NKTON Objectives:

(1) To determine the species composition, abundance, and distribution of ichthyoplankton in York Haven Pond; and (2) To investigate ichthyoplankton entrained at TMINS Unit 1 and 2 Intakes.

Far-Field Progress: Computer generated tables for the 1979 report were proofed and the written section was started.

Entrainment Progress: A first draft of the section for the 1979 report was completed.

TRA PNET Objectives:

(1) To determine the distribution and relative abundance of fishes in the Three Mile Island area vulnerable to trapnet; (2) To monitor the occurrence of diseased fishes; (3) To provide specimens for radiation analysis; and (4) To determine reproductive status for fishes throughout the year.

Progress: Samples were taken on 5-7 and 26-28 December (Table 1).

Ten fish of eight species weighing a total of 1.38 kg were taken on 5-7 December (Table 2).

No fish were taken in both collections at Station 11A2 and the 5-6 December collection at Station 9B2.

Eight fish of seven species weighing a total of 1.71 kg were taken on 26-28 December (Table 3).

"o fish were taken in both collections at Station 11A3 and the 27-28 December collection at Station 9B2.

No dead fish were observed in Decedber.

2370 259

4 SEINE Objectives :

(1) To determine the species composition of fish upstream and downstream from the TMINS Discharge vulnerable to seine; (2) To determine the relative condition factor for important species; and (3) To determine the reproductive status for fishes throughout the year.

Progress: Collections were made at the 10 stations on 5 and 27 December (Table 1).

A total of 1,385 fish of 11 species was taken on 5 December (Table 4).

Most fish (859), most species (8), and greatest biomass (0.20 kg) occurred at Station 13B5. The spotfin shiner was the most abundant species at all stations and comprised 88.1% of the total catch. The following fishes exhibited slight black spot infections:

spotfin shiner (74), bluntnose minnow (6), and comely shiner and spottail shiner (1 each). One spotfin shiner was parasitized by an anchor worm and one mimic shiner by a giochidium (larval clam).

No pattern of parasite infection was observed with respect to the loce_ ion of TMINS.

Sampling on 27 December yielded 824 fish of 12 species (Table 5).

Most fish (633) and greatest biomass (0.46 kg) occurred at Station 13B5 while most species (10) were found at stations 13B5 and 4A2. The spotfin shiner was most abundant and comprised 80.5% of the total catch.

No fish were taken at Station 9B6.

Fifty-three spotfin shiner and 22 bluntnose minnow exhibited slight black spot infections. One bluntnose minnow was parasitized by protozoans. Seven spotfin shiner and three swallowtail shiner were parasitized by glochidia.

No pattern 2370 260

5 of parasite infection was observed with respect to the location of TMINS.

IMPINGEMEKr OF FISH Objectives:

(1) To determine the numbers and species impinged on the river water intake screens; (2) To determine day-night differences in impingement frequency; and (3) To determine the extent of mortality of impinged fish.

Progress:

Impingement surveys were conducted at the Unit 1 and Unit 2 intakes on 10-11 and '!0-21 December (Table 1).

On 10-11 Dececher Ur.it 1 impinged 3 tesse11ated darters weighing a total of 4.0 g.

The catch was comprised of two juveniles and one adult; two specimens were dead (Tables 6 and 7).

No fish were Ospinged at Unit 1 on 20-21 December (Tables 8 and 9).

The total estimated impinge-ment from Unit 1 for December was 46.5 fish weighing 62.0 g (0.1 lb).

Unit 2 impinged 16 fish of 5 species weighing 17.2 g.

The catch was comprised of 14 young, 1 juvenile, and 1 adult; 14 fish were dead and 2 alive (Tables 10 through 13). All but two of the fish were impinged during the 10-11 December survey. The total estimated impingement from Unit 2 for December was 248 fish weighing 266.6 g (0.7 lb).

The total estimated impingement from TMINS during December was 294.5 fish weighing 328.6 g (0.8 lb).

2370 26i

6 ELECTROFISHING Objectives:

(1) To provide specimens for radiation analysis; and (2) To determine the relative abundance of fishes vulnerable to electrofishing in various parts of York Haven Pond.

Progress: Sampling was conducted on 3, 4, and 26 December (Table 1).

Twenty-four collections in 12 zones yielded 83 specimens of 9 species (Table 14). The carp (44 specimens), walleye (12), and quillback (8) were most abundant.

CREEL SURVEY Objectives:

(1) To determine the extent and success of sport fishing; and (2) To determine information on angler residence and use of catch.

Progress: All areas were surveyed on 1, 6, and 16 Dece=ber (Table 1).

On 21 December surveys were conducted only at York Haven Generating Station (YHGS) due to ice. Throughout December no surveys were conducted at the General Reservoir, West Dam, or East Dam during the 1700-2100 h period due to darkness.

The 19 anglers interviewed fished 20.00 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, caught 4 fish, and kept 2 (Tables 15 through 18). The mean catch per effort was 0.20.

Most anglers (15), all fish caught (4) and kept (2), and most hours fished (17.25) were recorded at the YHGS.

One channel catfish, two smallmouth bass, and one walleye were caught. Approximately 947. of the anglers interviewed lived in York or Dauphin counties. Most of the anglers reported they eat some of their catch.

2370 262

7 AMBIENT WATER OUALITY Objective: To determine the concentrations of selected water quality parameters in ambient river areas and the IMINS effluent.

Progress: Water quality samples were collected on 3 and 27 December at the five river stations (Table 1).

Data were analyzed and tabulated; results are presented in Table 19.

On 3 December values for dissolved oxygen, turbidity, total copper, and dissolved zine were highest at Station 11A1 (TMINS Discharge).

Values for pH, sulfate, and total zine were highest at stations 9B1, lAl, and 11A2, respectively.

On 27 December values for pH, dissolved copper, and dissolved zine were highest at Station 11A1; dissolved oxygen, total dissolved solids, and total cine were highest at 11A2. Values for water temperature and sulfate were highest at stations IA1 and 1A2 respectively.

Parameters, for which state water quality criteria have been established, were not exceeded at any station in December.
