HAZLETON CNVIRONMZNTAL ECCNCT3 4.0. ENVIRONf1 ENTAL SURVEILLANCE AND SPECIAL STUDIES The specificat' 1s related to Section 4.0 of the Environmental Technical Specifications (ETS) for Cooper Nuclear Station have been met.
This is a preliminary report summarizing the results obtained during the sixth year of operational studies (January-December 1979). A complete presentation and interpretation of the data will be included in an annual report which is currently in preparation. Modifications to Section 4.0 of the ETS occurring during 1979 will be discussed under the appropriate sub-sections.
4.1 BIOLOGICAL 4.1.1
' AQUATIC ECOLOGY 4.1.1.1 Surveillance, Study, and Evaluation Programs A.
Water Quality ~ Studies Duplicate samples for chemical and bacteriological analyses were collected monthly from January through December 1979 at three locations in the vicinity of Cooper Nuclear Station:
the intake, discharge canal, and near the downstream edge of the Station's mixing zone (RM 530).
In addition, fron itay through November water samples for complete chemical analyses were also collected upstream of. the Station (RM 534), and samples for limited analyses were collected at one location inmediately downstream of the discharge (Rt1532) and at another location outside the Station's mixing zone (RM 528).
With the exception of elevated tamperatures, Station operation had no apparent effects upon Missouri River water quality.
Flaximum increase in tenperature at the edge of the Station's nixing zone- (Rll 530) was 2.0C (3.6F).
Temperature increases were always well
[-
below the Nebraska Department of Environmental Control's (NDEC) maxium
- t..
11-3
HA2LETON CNVIRONMZNTAL. CC1'lNC2O criterion of 2.8C (5.0F) and' the ETS maximum limits of 5.6C (10.0F) during winter and 2.8C (5.0F) in~ summer.
The dissolved oxygen concentration was always above the NDEC mininum criterion of 5.0 mg/l and pli was always within the 6.5 to 8.5 range' established by the NDEC and ETS.
Neither parameter was affected by Station operation.
Total dissolved solids and specific conductance values were always below the maximun limits of 750 mg/l and 900 pmhos/cm at 25C, respec-tively, and were not affected by Station operation.
Turbidity values were occasionally 10% greater in the discharge canal than at the intake and thus exceeded the NDEC and ETS criterion; however,_ as in previous years spacial diffarences in turbidity were random and showed no trend attributable to Station operation.
J Bacterial contamination of the river was variable and was not influenced by Station operation. Fecal coliform densities exceeded the NDEC maximum limits of 400 in 90% of the samples and 200 organisms /100 ml at all
~ 1ocations on all sampling dates.
Total chlorine concentration in the discharge canal was always
<0.01 mg/1 and therefore did not exceed the ETS maximum criterion of 0.1 mg/1., Phenols concentrations exceeded the NDEC maxinum limit of 0.001 mg/1-at locations both upstream and downstrean of the Station on 7 of 12 collection dates.
Concentrations of aquatic nutrients and trace metals were not-affected by Station operation.
The maxinum recorded ammonia concentration of
- 0.72 mg/1-N was below the NDEC maximum limit of 1.0-mg/1.
i 11-4
HAZLETON ENVIRONMENTAL CC12NC2O The najor factors influencing water quality in the Missouri River near Cooper Nuclear' Station are upstream releases from. Lewis and Clark Lake,
. surface runof f, and upstream wastewater discharges.
Effective 7 December 1979 the ETS were modified and water quality studies were discontinued following the December collection period.
B.
Biological Studies 1.-
Periphyton Periphytic algae were collected from artificial substrates monthly from June through November 1979.
Species and biovolume composition and biomass production were determined for one upstream and three downstream locations on each collection date in accordance with the ETS.
In addition to the requirements of the specifications, samples were also collected from the
' discharge canal and analyzed for species and biovolume composition.
As in previous studies total periphyton density, biovolume, and bionass production showed considerable spacial and temporal variability and no trend relative to Station operation was evident.
Specie: composition and relative abundance were similar anong upstream and downstream sampling locations.
Excluding the midsummer sampling period, the periphyton density and biovolume composition were dominated by diatoms.
Abundant diatom taxa were similar to those reported in previous studies and included Navicula tripunctata var. s_rhironemoides, Gomphonema angustatun, G. parvulum, and Biddul_phia laevis.
Green and blue-green algal abundance was highest in midsummer with CladopMra glomerata and Lyngbya _ diguetii, respectively, being the nost abundant taxa.
The periphyton.connunity in the discharge canal was L
generally; dominated by the diatom Navicula,l_uzonensis.
Blue-green algal II-5
HAZLETON GNVIRONMENTAL CCENC]:3 relative _ abundance (primarily L,. diguetii_) was also higher at the discharge canal than at other locations. Differences in species composition in the discharge canal versus other locations have been the only noted e*fect of the Station's thernal ef fluent on the periphytic algal community.
This effect is localized and not considered a significant adverse impact.
A 7 December 1979 modification to the ETS resulted in the deletion of the periphyton study frem the monitoring program.
2.
Aquatic Macroinvertebrate and Benthic Organisms Missouri River benthic and aufwuchs communities near Cooper Nuclear Station were sampled in accordance with the ETS at one upstream and three downstrean locations on 27 June, 9 August, and 30 October 1979.
In addition to the-requirements of the technical specifications, macroinvertebrate
~
samples were also collected from multiple-plate samplers located in the Station's discharge canal.
A total of 57 taxa was collected by ponar dredge in 1979.
Benthic densities were within the range recorded duririg previous studies and 2
2 ranged from 101 organisms /m at RM 534 in August to 6281/m at RM 530 in October.
The number of benthic taxa collected at each location ranged from 4
5 to 22. Diversity indices vared fron 1.23 at RM 532 to 2.87. at RM 530 both occurring in August.
Immature Tubificidae with capilliform chaetae,
. Linnodrilus cervix and L. hoffmeisteri were the most common benthic taxa -
encountered.
The composition of the aufwuchs community was similar
- to' that recorded from previous years.
Densities on the artificial substrates 2
2 ranged fron 4580 organisms /m at RH 534 to 43570/m at RM 532 both occurring 'in-June.
Species diversity indices were similar at each location II-6
HAZLETON CNVIRONMENTAL CCGNC :'3 during all sampling periods and ranged from 2.15 in June to 3.28 in August.
A total of 90 taxa was encountered on the multiple-plate samplers with Caenis, Hydropsyche, Polypedilum, and Rheotanytarsus being the most abundant.
Macroinvertebrate multiple-plate densities on the samplers 2
placed in the discharge canal ranged from 4025 organisms /m in August 2
to 82265/m in June. As at the river locations, Caenis, Hydropsyche, Rheotanytarsus, and Nais were the most abundant taxa.
Diversity indices ranged from 2.43 in June to 3.57 in August, Results of these analyses indicate that the heated water g
from Cooper Nuclear Station has not adversely affected the aquatic macro-invertebrate populations in the Missouri River.
Sampling of aquatic macro-invertebrate and benthic organisms was discontinued following a 7 December 1979 revision to the ETS.
3.
Fisheries Study Adult and juvenile fish were sampled monthly from May through November 1979 in accordance with the ETS.
Sainples were collected by shoreline electroshocking and seining at locations above and below the Station and on both sides of the Missouri River.
A total of 759 fish was collected by electroshocking during 1979 which was a lower total catch than in previous yecrs.
The low total catch was primarily attributed to a lower catch rate at the discharge canal. During previous studies fish have been attracted to the thermal
' effluent.during spring and fall collection periods.
During 1979 a spring and fal!' Station shutdown precluded thermal attraction and resulted in a lower ca tch.
Species' composition and relative abundance in 1979 were similar to l
-those recorded in: previous years.
Predominant' species collected by II-7
HAZLETON ENVIRONMENTAL CCCNC]
electroshocking included carp, gizzard shad, river carpsucker, goldeye, and freshwater drum which collectively comprised 85.4% of the total catch.
Species composition in the 1979 seine haul collections was similar to that reported in previous studies and total catch was within the range of those previously reported.
Predominant species included silver chub, river shiner, channel catfish, emerald shiner, red shine and freshwater drun which collectively comprised 83.7% of the catch. As in previous years the thermal effluent did not appear to influence the distribution of fish collected by seining.
Ane composition, average size, and food habits of selected game fish in 1979 were similar to those reported in preoperational and prior operational studies. Data from the adult and juvenile fish studies indicate that the operation of Cooper Nuclear Station has not adversely affected fish populations in the Missouri River. Ef fective 7 December 1979 the requirement for fisheries studies was deleted from the ETS and sampling was discontinued.
4.
Fish Larvae Distribution Fish larvae samples were collected weekly from flay through July 1979 at three locations along a horizontal transect immediately upstream of the Station's intake structure.
Vertically integrated samples
. were collected from near each shoreline and at mid-channel.
Species composition and abundance of the larval fish assemblage were determined and the percentage of. this assemblage subjected to entrainment was calculated.
The larval fish assemblage consisted primarily of fresh-water drum (74.0%), cyprinids (10.6%), and catostomids (10.5%).
Total larval abundance followed seasonal trends established in previous studies and
- was. primarily determined by the abundance of freshwater drum.
Densities increased
~
II-8
HAZLETON ENVIRONMENTAL CCCNCZ3 from early llay to a peak on 4 July.
Following the 11 July collection, 3
densities declined rapidly.to less than 4/100 m by 25 July.
As in previous studies larval densities were higher at the shoreline locations than in mid-channel.
During previous studies densities tended to be highest along the tiebraska shoreline; however, in 1979 densities were generally highest along the Missouri shoreline. Densities were signiff-cantly higher (p 10.05) on the flissouri shoreline on 3 of 10 collection dates.
Based on the horizontal distribution of fish larvae, percent. cooling water diversion, and channel configuration, an estimated 3.3%
of the larvae passino the Station during 1979 were entrained.
The monitoring requirenents for fish larvae studies were deleted from the ETS effective 7 December 1979.
4.1.1.2 Plant Cooling Water Systens Fish Entrapment Limits Samples of fish impinged on the traveling screens were collected in accordance with the ETS.
Sampling was conducted hourly at least twice per nonth with the July, August, and Septenber collections being performed during hours of darkness.
A total of 270 fish, representino 15 taxa, was collected during 26 hourly collection periods in 1979 (Table 1).
ilonthly impinnement rates ranced fron 0 to 30 fish /hr with hiqher rates oinciding with the occurrence
- of youno-of-the-year gizzard shad and freshwater drum.
The most connon species inpinged were oizzard shad, freshwater drun, and carp which collectively comprised 88.5% of tbo total. Game fish (excludino freshwater drun) comprised 5.9% of 'the fid irminced.
Snecies cornesition am' rel.,ti'te abundance of -
fish inpinged in 1979 were similar to those in previous years (Table 2).
II-9
HAZLETON ENVIRONMENTAL CCIENC]')
As in previous years diurnal rates were lower than nocturnal rates (Table 3). Peak impingement of 46 fish /hr occurred during a nocturnal samplia period in August.
This rate was below the 90 fish /hr limit established by the ETS.
Fish. impinged on the traveling screens at Corper Nuclear Station are returned to the river via a continuous wash systen.
Of the fish impinged during 1979, 59% were classified as alive and active (Table 4) and night have survived-the inpingement process.
