2 COMPLIANCE UITH 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 vith all I agrams specified in the ETS and detailed in the Procedures Document was achieved in August (Table 1).

The summer fish population estimate program initiated on 30. Tune was concluded on 13 August. The ETS sampling requirements for ichthyo-plankton for 1981 have been completed as of 31 August.

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

MACROINVERTEBRATES 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 4 and 17 August (Table 1).

Enumeration and determination of dry weights of the macroinvertebrates have been completed through 17 August; identification of specimens has been completed through 4 August.

ICHTHYOPLANKTON Objectives :

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

Far-Field Progress: Day / night samples taken on 4, 11, 18, and 25 August (Table 1) yielded totals of 853, 310,1145, and 448 larvae, respectively.

1 Night collections yielded 93.1% of the total catch.

3 All s uples have been sorted'and the specimens stored for identification. Identification of samples taken through 22 July is complete, Identification of 27 July samples and data coding and keypunching of completed data are in progress.

The ETS sampling requirements for ichthyoplankton far-field for 1981 have been completed as of'31 August.

Entrainment Progress: Ichthyoplankton surveys were conducted at Units 1 and 2 on'4-5 and 18-19 August (Table 1). At Unit 1, 539 ichthyo-planktors (474 surface, 65 oblique) were taken on 4-5 August. The 18-19 August samples yielded 51 specimens (36 surface,15 oblique).

Ac Unit 2,13 ichthyoplanktors (5 surface, 8 oblique) were taken on 4-5 August. The 18-19 August collection yielded 15 specimens (10 surft.ce, 5 oblique).

j Identification of entrainment specimens has been completed through 27 May.

The ETS sampling requirements for ichthyoplankton entrainment for 1981 have been completed at of 31 August.

TRAPNET Objectives:

6 shiner, 5 spottail ahiner, 3 pumpkinseed, 3. smallmouth bass, 2 mimic shiner, 2 tesse11ated darte23 and 1 bluegill.

0~ comely shiner had spinel curvature.

No pattern of parasite infection or anomalies was observed with respect to the location of TMINS from either collection.

IMPINGEMENT OF FISH Objectives:

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

}

l Progress:

Impingement surveys were conducted on 13-14 and 26-2'/

August at the TMINS Unit 1 and 2 Intakes (Table 1).

Unit.1 impinged-i f

47 fish of 8 species weighing 25.2 g.

Most fish were young and dead I

(Tables 6 through 9).

Fish biomass and numbers were. highest 'during i-the 26-27 August survey. More fish were collected at 1200 h than r

durinF the other survey periods. The estimated impingement at Unit 1 for Iugust was 728 fish weighing 390.6 g (0.9 lb).

i Unit 2 impinged 15 fish of 7 species weighing 14.6 g.

Most fish were young and all were dead (Tables 10 through 13). Fish biomass and numbers were highest during the 26-27 August survey.

The estimated impf ngement for August from Unit 2 was 232 fish weighing 226.3 g.(0.5 lb).

The total estimated impingement at TMINS in August was 960 fish i

veighing 616.9 g (1.4 lb).

1 ELECTSQEJSHING Objectives:

7 Progress: Sampling was conducted on four nights in August (Table 1).

l Twenty-four collections in 12 zones yielded 666 specimens of 20 species (Table 14). The pumpkinseed (168 specimens), smallmouth-bass (130),

bluegill (96), quillback (73), and redbreast sunfish (68) were most abundant.

A total of 55 fish was tagged for movements studies. Two channel catfish were sacrificed for radiation analysis.

MOVEMENTS OF FISHES Objective: To determine if fishes in waters receiving the TMINS effluent mix with fishes from other areas.

Progress: A total o.'! 71 fish was tagged and six previously tagged fish were recaptured in August. Recaptured fishes incin'.d the rock bass (1 sp _ 'imen), smallmouth bass (4), and largemouth bass (1). The rock bass made a 1.2 km complex movement. One smallmouth bass made a 0.1 km complex movement; the other three were recaptured in the same areas in which they were tagged. The largemouth bass was recaptured in the same area in which it was tagged.

CREEL SURVEYS Objectives:

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

Progress: Creel surveys were conducted in all areas on 2, 15, 20, and 25 August (Table 1).

The 388 anglers interviewed fished 746.65 hours7.523148e-4 days <br />0.0181 hours <br />1.074735e-4 weeks <br />2.47325e-5 months <br /> and caught 800 fish (Tables 15 through 18). The actual harvest was 139 fish or 17.4% of the total catch. The mean catch per effort (c/e) was 1.07.

Most anglers (239), most hours fished (520.45), largest total

. ~.

.~

8 catch (596), and largest total harvest '(83) were recorded from the General Reservoir. The highest mean c/e (1.61) occurred at the East Dam.

Smallmouth bass (512 specimens) were caught in greatest numbers

+

and accounted for 64.07. of the total catch. Other common species caught included the channel catfish (88), rock bass (60), and unidentified sunfishes (58).

Approximately 61% of the anglers interviewed lived.in York or Dauphin counties. Most of the anglers reported they eat some of their catch.

AMBIENT WATER QUALITY concentrations of aelected water quality -

Objective: To htermina parameters in ambient river areat and the TMINS effluent.

Progress: Water quality sam,iles were collected on 4 and 17 August at the five river stations (Table 1). Data are currently being analyzed; results will be pres'ated in the September progress report.

The water quality samples collected in July have now been analyzed; I'

results are presented in Table 19.

On 6 July values for dissolved oxygen, alkalinity, total dissolved solids, and total zine were highest at Station 1Al (located above the TMI Discharge). Values for dissolved r

zine (11A1), eulfate and dissolved copper (11A2), and turbidity (9B1) were highest at stations located at or below the Discharge.

On 20 July values for sulfate and total dissolved solids were i

highest at Station 1A1; alkalinity and dissolved zine were highest at 1A2. Values for total copper, turbidity, and dissolved oxygen were highest at Stations 11A1,11A2, ani 9B1, respectively.

4 I

l

9 Parameters, for which State water quality criteria have been established, were not exceeded at any station on 6 and 20 July.

POPITLATION ESTIMATES OF FISHES Objectives:

(1) To determine if differences exist in fish populations between areas receiving the TMINS effluent; and (2) To estimate populations in other areas available for recruitment.

Progress: Summer population estimate sampling was terminated af ter six collections were made in August (Table 1).

Sufficient recaptures were made to compute estimates in most zones. Data from 4 -

each collection will be tabulated and results presented in the 1981 annual report.

THERMAL PLUME MAPPING Objectives:

(1) To determine temperature data; (2) To define the it discharge plume; and (3) To check the accuracy of the analytical plume model.

Progress:

The' thermal plume was mapped on 31 August (Table 1) to meet the requirement that a plume map be conducted during the summer 3

low river flow (less than 10,000 cfs; 283.2 m /s). During the 31 August 3

mapping the river flow was 4,480 cfs (126.9 m /s); maximum AT at the Discharge was 0.4 C (Table 23). River water temperature varied + 2.5 C between the Unit 1 Intake and 1900 m downstream of the TMINS Discharge; maximum water temperature occurred 1000 m downstream of the Discharge.

The plume was limited to the immediate area of the Discharge.
