2 COMPLIANCE WITH ENVIRONMENTAL TECHNICAL SPECIFICATIONS (ETS)
Objectives: 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 Procedures Document was achieved in May (Table 1).
A program by program summary of the progrese for May follows.
MACROINVERTEBRATES Objective: To describe the diversity and distribution of the benthic macroinvertebrates occurring at the five benthos sampling i
stations near TMINS.
Progress: Replicate (4) benthos samples were taken on 4 and 18 May (Table 1).
Enumeration, determination of dry weights, and preliminary identification of macroinvertebrates have been completed through 18 May.
ICHTlWOPLANKTON 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: Day / night sampics were taken on 5,12, 20, and 26-27 May (Table 1). A total of 7,259 larvae was captured, 331 in day samples and 6,928 at night. Totals for each week were 230, 1067, 2274, and 3688, respectively. Water temperatures ranged from 14.0 to 23.0 C.
Samples have been identified and tabulated through 12 May.
Sorting of 8 June samples is in progress.
3 ENTRAINMENT Progress:
Ichthyoplankton surveys were conducted at Units 1 and 2 on 12-13 and 26-27 May (Table 1). At Unit 1, 184 ichthyoplanktors (103 surface, 81 oblique) were taken on 12-13 May.
The 26-27 May sample yielded 96 specimens (47 surface, 49 oblique).
At Unit 2,131 ichthyoplanktors (91 surface, 40 oblique) were taken on 12-13 May. The 26-27 May collection yielded 219 specimens (88 surface, 131 oblique).
TRAPNET Objectives: -(l) To determine the distribution and relative abundance of fishes in the Three Mile Island area vulnerable to trapnet; (2) To provide specimens for movements studies; (3) To monitor the occurrence of diseased fishes; (4) To provide specimens for radiation analysis; and (5) To determine reproductive status for fishes throughout the year.
Progress: Samples were taken on 6-8 and 20-22 May (Table 1).
A total of 104 fish of 12 species was taken on 6-8 May (Table 2).
Most fish (47) and most species (8) were taken at Station 1A3 while greatest biomass (4.62 kg) occurred at 9B2. The pumpkinseed and rock bass were most-abundant and comprised 60.6% and 11.5% of the total catch, respectively.
One Leponis hybrid (redbreast sunfish X pumpkinseed) was collected at Station 11A2. Four rock bass and one brown bullhead were tagged. Three previously tagged rock bass were recaptured.
Parasites and anomalies observed included 3 pumpkinseed with eye protuberances,1 yellow perch with slight black spot, I redbreast sunfish with a leech, and 1 redbreast sunfish with an anchor worm.
4 Some 101 fish of 12 species was taken on 20-22 May (Table 3).
Most fish (43) were taken at Station 9B2, greatest biomass (9.08 kg)
-at 1A3, and most species (8) at 1A3 and 9B2. Common fishes included the pumpkinseed (30.7% of the total catch), white crappie (28.7%),
and rock bass (11.9%). Six rock bass, 3 brown bullhead, and 1 channel catfish were tagged. One previously tagged rock bass was recaptured.
Four male pumpkinseed were ripe. Three spotfin shiner exhibited slight black spot, 1 rock bass was parasitized by a leech,1 brown bullhead bore abdominal ulcers, and 1 channel catfish had a caudal fin fungus.
Dead fishes observed in the study area included 1 common carp, i quillback, and 1 channel catfish.
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 6 and 2u May (Table 1).
A total of 4,442 fish of 19 species was taken on 6 May (Table 4). Most fish (1,590) and most species (9) were taken at Station 9B6 while greatest biomass (388.7 g) occurred at 10B5. The spotfin shiner was the most abundant species at all stations except 10A2 and comprised 94.8% of the total catch. The numters of fishes bearing slight black spot infestations remained high and included the spotfin shiner (179 specimens); bluntnose minnow (5); spottail shiner (3);
common shiner (2); and blacknose dace, fallfish, pumpkinseed, and bluegill (1 each). Two pumpkinseed exhibited eye protuberances,1 spotfin shiner had spinal curvature, and 1 spottail shiner and 1 pumpkinseed were
5 parasitized by anchor worms. Two, male bluntuose minaow were tuberculate and four tesse11ated darter were gravid.
A total of 2,619 fish of 20 species was taken on 20 May (Table 5).
Most fish (937), most species (13), and greatest biomass (420.2 g) were taken at Station 13B5. The spotfin shiner was the most abundant species at all stations except 9Al and comprised 88.8% of the total catch. Young of the chain pickerel and white sucker were taken for the first time this year. Occurrences of slight black spot infestations remained numerous and-included the spotfin shiner (150 specimens);
bluntnose minnow (19); common shiner, spottail shiner, and shorthead redhorse (2 each); and blacknose dace and fallfish (1 each).
Other paras',tes and anomalies were 1 smallmouth bass with an anchor worm, 1 bluegill with a leech, and 1 pumpkinseed with eye protuberances.
Two, male bluntnose minnow were tuberculate and one tesse11ated darter was gravid.
No pattern of parasite infection was observed with respect to the location of TMINS from either May sample.
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 _mpingement frequency; and (3) To determine the extent of mortality of impinged fish.
Progress:
Impingement surveys were conducted weekly (6-7, 11-12, 20-21, 27-28 May) at the TMINS Unit 1 and 2 Intakes (Table 1).
Unit 1 impinged 7 fish of 6 species weighing 844.1 g (Tables 6 through 13).
Most fish were young and all were dead. Fish biomass and numbers were highest 3uring the 11-12 May survey. More fish were collected at 0400 h than du:ing the other survey periods.
The estimated Dmpingement for Unit 1 for May was 54 fish weighing 6,541.8 g (14.4 lb).
L
6 Unit 2 Lmpinged 31 fish of 5 species weighing 328.6 g (Tables 14 through 21). Most fish were young and dead. Fish numbers and biomass were highest during the 27-28 May survey. The estimated impingement for May from Unit 2 was 240 fish weighing 2,546.6 g (5.6 lb).
The total estimated impingement at TMINS during May was 294 fish weighing 9,088.4 g (20.0 lb).
ELECTROFISHING Objectives:
(1) To provide specimens for radiation analysis and movements studies; and (2) To determine the relative abundance of fishes vulnerable to electrofishing in various parts of York Haven Pond.
Progress: Sampling was conducted on four nights in May (Table 1).
Twenty-four collections in twelve zones yielded 859 specimens of 18 species (Table 22). The smallmouth bass (193 spectmens), quillback (175), shorthead redhorse (149), and pumpkinseed (121) were most abundant. A total of 112 fish was tagged for movements studies.
MOVEMENTS OF FISFES Objective: To determine if fishes in waters receiving the TMINS effluent mix with fishes from other areas.
Progress: A total of 127 fish was tagged and 35 previously tagged fish were recaptured in May. Recaptured fishes included the channel catfish (1 specimen), rock bass (25), and smallmouth bass (9). The channel catfish mada a 2.0 km complex movement.
One rock bass was recaptured twice during May, bringing the total number of recaptures to 26.
Eight rock bass moved upstream (distances of 13.4 to 92.5 kn),
three moved downstream (0.2 to 9.5 km), six made complex movements (1.0 to 81.3 km), and nine were recaptured in the same areas in which they were tagged. Three smallmouth bass made complex movements (0.3 to 3.0 km); the remaining six smallmouth bass were recaptured in the same areas in which they were tagged.
7 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 3,11,16, and 28 May (Table 1).
The 564 anglers interviewed fished 943.85 heers and caught 1,838 fish (Tables 23 through 26). The actual harvest was 452 fish or 24.6% of the total catch. The mean catch per effort (c/e) 4 was 1.95.
Most anglers (198), most hours fished (376.45), and largest total harvest (176) were recorded at the York Haven Generating Station.
The largest total catch (731) was recorded at the East Dam, and the highest mean c/e (4.29') occurred at the West Dam.
Walleye (607 specimens) were caught in greatest numbers. Other common species included the smallmouth bass (574), rock bass- (507),
unidentified sunfishes (31), channel catfish (29), and conson carp (25).
Approximately 76% of the anglers lived in York or Dauphin counties.
Most of the anglers reported they eat some of their catch.
AMBIENT WATER QUALITY Objective: To determine concentrations of selected water quality parameters in ambient river areas and the TMINS effluent.
Progress: Water quality samples were collected on 4 and 18 May at the five river stations (Table 1).
Data are currently being analyzed; results will be presented in the June 1981 progress report.
The water quality samples collected in April have now been analyzed; results are presented in Table 27.
On 7 April values for turbidity, sulfate, and total zine were highest at Station 1Al (located upstream from the TMINS Discharge);
i L
8 total dissolved solids were highest at 1A2. Dissolved zine values were highest at Station 11A2 (downstream from the Discharge)., Values for water temperature, pH, dissolved oxygen, and alkalinity were highest at Station 9Bl.
On 20 April values for dissolved oxygen and total dissolved solids were highest at Station 9Bl. Sulfate, pH, and turbidity values were highest at Stations IA1,11A1, and 11A2, respectively.
' Parameters, for which State water quality criteria have been establishad, were not exceeded at any station on 7 or 20 April.
