1. INTRODUCTION AND

SUMMARY

Vermont Yankee Nuclear Power Corporation's generating station in Vernon, Vermont, established four operating records in 1982.

Its thermal capacity factor for 1982 was 94.0%,. the best production record for all boiling water reactors in the world in 1982.

The highest capacity factor, achieved by Vermont Yankee in prior years was 81.1% in 1981.

Power was generated during 8409 hours0.0973 days 2.336 hours 0.0139 weeks 0.0032 months of 1982, 96.0% of the time.

During the hours of power generation, the average power level was 98.0%.

Figure 1.1 is a graph of the plant's record of power production in 1982.

Environmental studies of the Connecticut River near Vernon, Vermont, were conducted in 1982 in accordance with a schedule of such studi6s detailed in Vermont Yankee's NPDES permit.

Addi-tional studies were conducted in 1982 under the study program, approved by the states of Vermont and New Hampshire, for Pro-ject SAVE.

That-project has been undertaken to ascertain whether some operation in the period mid-May to mid-October in open or hybrid cycle modes of condenser cooling could be util-ized in order to increase energy production without adversely affecting the Connecticut River ecosystem.

Under the conditions established, for this test program, Vermont Yankee utilized hybrid/open cycle cooling for the last two weeks in May and from mid-September to mid-October.

Special'.

biological studies, augmenting the routine NPDES studies, were conducted throughout the five months, May 16 to October 14, when Vermont Yankee's NPDES permit mandates closed cycle con-denser cooling.

The results of these special studies have been reported separately (Binkerd et al. 1983).

Eight sampling stations in the Connecticut River near Ver-non, Vermont, were used in earlier studies.

The approximate lo-cations of these stations are shown in Figure 1.2.

Collections were made at only six of these stations in the 1982 studies.

The locations of these six in river miles north and south of Vernon Dam are shown below.

SUMMARY

OF RESULTS Water Quality Studies The maximum Connecticut River discharge of spring run-off occurred in 1982,.as.

is usually the case at Vernon,:in April.

Mean discharge for that month was 39,503 cfs, a greater April flow rate than the April average for the previous 17 years, The maximum daily discharge was 70,889 cfs on April 19 and the maximum hourly discharge, 74,695 cfs, occurred on April 18 and

19.

River flow rates in the other months of 1982 were gener-ally low relative to those observed in the previous 17 years..

Flows were particularly low in September and October, when the maximum daily discharge was smaller than had occurred in the previous 17 years.

Despite the relatively low river flow rates in'September.

and October, nonew record temperatures of the river were ob-served then, either upstream or downstream of Vermont Yankee.

However, in December record hourly temperature maxima, relative to previous years of study, were observed at both Monitor 7, upstream of Vermont Yankee, and at Monitor 3, downstream of the plant.

At Monitor 3, a record monthly maximum occurred in November also.

The monthly-mean temperatures in November and December were also greater than had been recorded in-the previous 14 years of temperature data.

Vermont Yankee operated in 1982, during the period of open

.-cycle operation allowed under its NPDES permit,.within the three thermal criteria imposed upon such operation by the permit.

These conditions require that Vermont Yankee's discharge not effect a temperature at Monitor 3 greater than 65*F; the maximum hourly mean temperature observed there during NPDES open cycle operation was 58.5*F on October 25.

The maximum allowable rate.

of temperature, change between successive hourly.average tempera-tures at Monitor 3 is-50F per hour; the maximum observed was 3.2 0 F per hour on March 8.

The maximum allowable increase in river temperature effected by Vermont Yankee's discharge is 13.4 0F; the maximum difference observed between downstream Moni-tor 3 temperajure and upstream Monitor 7 temperature was 9.10F on October.. 29.

The average dissolved-oxygen concentrations for the months of April and June at Monitor 7 were greater in 1982 than had been observed in the prior 12 years.

The monthly maximum D.O.

at that upstream station was also larger for those two months than in earlier years.

At the downstream monitoring station, mean D.O. concentrations for April and June were also greater than in former years.

And record maximum D.O. concentrations were observed there in March and April.

With one exception, all pH maxima and minima recorded in 1982 were within extremes noted in earlier years.

The May minimum of 6.8 at Monitor 3 was 0.1 pH unit lower than the previous minimum observed* there in May.

Grab samples were-collected at Stations 3 and 7 on four dates in 1982 and analyzed for sixteen water quality parameters.

With two minor exceptions, the concentrations of all parameters were found to be within ranges observed in former years.

The t-otal iron concentration in the September sample from Monitor 3 was 0.02 mg/l less than the earlier minimum there and the chlor-ide ion concentration in the March sample at Monitor 7 was 0.5

mg/l greater than the prior maximum there.

Biological Studies Diatoms predominated, as in earlier study years, in the net phytoplankton samples collected via the monitor pumps at Stations 3 and 7.

Diatoms constituted 50% or more of all.the Monitor 7 samples and all the :Monitor 3 samples except that of January..

In general, the species composition of the 1982

.samples was similar to that of earlier years.

Algal concentrations in the net collections of 1982 were less than the mean concentrations observed in the years 1970-74 in all months but January and February at Station 7 and in all months but July at Station 3.

Only the 119 algal units per lit~er: observed at:Monitor 7 in:January was more than two' stand-ard deviations greater than the monthly means of 1970-74.

The concentrations of phy-toplankters. observed in the July sample at Monitor 3 exceeded the mean count. of the years 1970-74 by less than two standard deviations.

However, this July Monitor 3 count was greater than that predicted by the application of a statistical analysis of the 1970-74 data to the July count ob-served at upstream Station 7 in July, Zooplankton concentrations in the monitor samples of 1982 were generally low.

All zooplankton counts in 1982 were less than the mean counts observed for the corresponding month in the years 1970-1974.

All Monitor 3 concentrations in 1982 were within-the 95% confidence limits for a. concentration pre-dicted from upstream counts by a statistical analysis of 1970-74 zooplankton data.

Rotifers,. as in prior years, were the predominant zooplank-ters in the 1982 samples.

They constituted at least 50% of the organisms found in 11 of the 12 Station 3 samples and in 8 of the Station 7 samples.

The most commonly occurring rotifer was Philodina sp., which was found in 18 of the 24 monitor samples.

Relatively large percentages of protozoans, particularly Vorti-.

cella sp., were found in the fall and winter samples.

A total of 145 taxa were observed in the 1982 benthos collections by Ekman dredge and Henson trap.

Fifty-six taxa were found in Station 2 samples, 57 in Station 3 samples, 77 in Station 4 samples, and 85 in samples collected at Station 5.

Of the 120 genera found in the 1982 samples,.73 genera were observed in the ten Henson trap collections and 99 genera were found in the samples collected by Ekman dredge.

The number of genera observed in 1982 at Stations 3, 4,

and 5 was larger than in earlier years.

The number found in Station 2 samples,} 39 genera, was only one less than was found there in 1981.

Chiro-nomid larvae were the predominant organisms in 15 of the 19 LA samples collected upstream of Vernon Dam.

In the downstream samples, caddis fly larvae were dominant in early summer samples.

A variety of forms predominated in late summer and fall--clado-cerans, planarians, and amnicolid snails.

Studies of the extent of fish. impingement of Vermont Yah-kee's traveling screens were conducted during both open/hybrid cycle and closed cycle operations in 1982.

The mean number of fish impinged per test day during open/hybrid.cycle operation was.25; the mean weight per test day was 192 grams.

The great-est impingement rate was observed in September, 102 fish and 295 grams per test day.. The average number of fish impinged per closed cycle test day in 1982 was 0.2 fish, the average weight per closed cycle test day was 3.8 grams (0.13 ounces).

More than 8,000 fish, weighing approximately 2 tons, were captured in 1982 in 350 collections made by trap net, gill net, seine haul, and electrofishing.

Twenty-six species were collected at all locations.

Twenty-two species were identified in the collections upstream of Vernon Dam; twenty-one in the collections south of Vernon Dam.

All species observed in 1982 have been collected in the studies of prior years.

Blueback herring and American shad, first observed in 1981, were captured in 1982 also.

These species were introduced into the Vernon.

reach of the Connecticut River in releases of shad conducted in the program of anadromous fish restoration to the river.

One specimen of Atlantic salmon was taken in a trap net south of Vernon Dam in May, and two salmon were observed to have been impinged, in May also, on Vermont Yankee's circulating water traveling screens.

Comparison of the species composition by number and weight, reduced to a percentage basis, of the. fish populations collected in 1982 with such percentages of earlier surveys shows that only the percentage in 1982 of yellow perch by number is outside the extremes observed in prior years.

Yellow perch constituted 22.5% by number of the fishes captured in 1982.

The previous*

maximum for this species was 17.6% in 1981.

The age-growth data of 1982 for white perch and yellow perch collected north of Vernoh Dam are not significantly different from that of the years. 1969-73.

However, the data for these species collected south of the dam, and for walleye and small-mouth bass, both north and south of the dam, appear to indicate an increased growth rate relative to the 1969-73 data.

The possibility that Vermont Yankee's discharge of warm condenser cooling water to the river may have contributed to an apparent change in growth rate of some fish species will be investigated further in 1983.

No significantly adverse impact of this discharge on the river's ecosystem was discerned by the 1982 ecological studies.

CONNECTICUT RIVER DISCHARGE Connecticut River discharge in 1982 at Vernon, Vermont, computed from.the records of the Vernon Hydroelectrid Station at Vernon Dam, is summarized in Figure 2.1.

The mean flow rate, the maximum daily average flow rate, and the minimum daily average flow rate are plotted for each month of the year.

These data are also shown in Tables 2.1 and 2.2, along with summary data for the years 1965-81, years for which data have been reported in previous volumes of this series of reports.

Annual maximum discharge rate in 1982 occurred, as is usually the case at Vernon, in April.

Mean discharge for that month was 39,503 cfs, a flow rate more than one standard-deviation greater than the average April discharge recorded in the previous 17 years,.

29,200 cfs (Table 2.2).

The maximum mean daily discharge in 1982 was. 70,889 cfs on April 19 and the maximum hourly discharge,.

74,695.cfs, was'.observed from 2200 on.April.18 to 0400 on April 19.

Mean discharge for all months in 1982 was within the extremes observed for the corresponding month in the prior 17 years, but the 1982 means were lower in all months except April, as noted above, and June than the 1965-81 means for each of the months.

(Table 2.2).

The minimum daily average discharge observed in each month of 1982 was within extremes that had occurred in the previous 17 years.

But the maximum daily flow rate in two months, September and October, was smaller than had been observed in those months in the years 1965-81 (Table 2.1).

A summary by month of the occurrence of minimum flow at Vernon in 1982 is shown. in Table 2.3.

For the year, 248 periods of minimum flow occurred on 234 days.

Minimum flow was passed during 2,899 hours0.0104 days 0.25 hours 0.00149 weeks 3.420695e-4 months , 33.1% of the time.

More than 50% 'of these hours of minimum flow in 1982 occurred in the months August, September, and October when a minimum discharge occurred during 1,496 hours0.00574 days 0.138 hours 8.201058e-4 weeks 1.88728e-4 months , 67.8%.of the time.

By contrast, in 1981 minimum flow was passed only 28.5% of the hours in these three months.

The duration of the minimum flow periods ranged from one hour to 94 hours0.00109 days 0.0261 hours 1.554233e-4 weeks 3.5767e-5 months ; the average duration was 11.7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months .

By compari-son, the longest period of minimum flow was 47 hours5.439815e-4 days 0.0131 hours 7.771164e-5 weeks 1.78835e-5 months in 1981, 62 hours7.175926e-4 days 0.0172 hours 1.025132e-4 weeks 2.3591e-5 months in 1980, and 65 hours7.523148e-4 days 0.0181 hours 1.074735e-4 weeks 2.47325e-5 months in.1979.

Mean flow in September 1982 was greater than the mean discharge of September 1978 (Table 2.2); but, as noted above, the maximum daily September discharge in 1982 was less'than that observed in 1978 (Table 2.1).

RIVER TEMPERATURE Temperatures of Connecticut River water are measured-continu-ously by temperature monitoring systems, installed in buildings on the Vermont shore of the river at Sample Station 7, upstream of Vermont Yankee, and at Station 3, downstream of the plant.

The temperature data of 1982, reduced to hourly, daily, and monthly means, are shown in Tables 3.1 for Station 3, and in 3.2, for Station 7, at the end of this section of the report.

These data are summarized graphically in Figures 3.1 and 3.2.

The maxima and minima'in those figures are hourly means.

Temperature data[have been collected continuously since 1968 at Station 3 and since 1970 at Station 7' Figures 3;1 and 3.2 also show, in shaded areas, the maximum and minimum hourly mean temperature that has been observed for that month in any of the previous years.of study.- The 'shaded area is divided by a line

.that connects.the points of mean'monthly temperatures computed from the data of all previous years for that month.

Monthly mean temperatures observed at the downstream location, Station 3, were greater in January through March, May, and October through December than the 14 year mean for those months in the years 1968-1981.

The November and December means exceeded the highest mean that had been observed in any one of the previous 14 years.

The November 1982 mean' was 48.8 0 F; the prior record mean for that month was 48.7 0 F, in 1978.

The highest December mean of the years 1968-1981, 38.20F, was also observed in 1978; the 1982 mean for December was 38.4 0 F.

MONTHLY AVERAGE MONTHLY MINIMUM

The maximum hourly means observed in-November afid December were greater also than the hourly maxima previously observed then.

The November maximum of 58.2 0 F exceeded that of 5705°F in 1971 and the December maximum of 46.8*F was higher than the prior record for that month, 44.5°F in 1978.

No record hourly minima were observed at Station 3 in 1982.

At the upstream monitor location, Station 7, monthly mean temperatures were higher than the.12 year means of the years 1970-1981 in May and October through December.

The March and June means were lower than the monthly mean in any prior year of record.

The March 1982 mean was 32.2 0F; the previous low monthly mean was 32.6*F in 1971.

The June 1982 mean of 63.81F was lower than the earlier record, 64.1 0 F in 1972..

Two record hourly mean temperatures-were observed at Station 7 in 1982.

The 32.0 0 F minimum in April was lower than the prior

.record of 33.0°F, observed in 1978.

The 42.41F December 1982 maximum exceeded the highest hourly mean temperature previously observed at Station 7, 41.7°F in 1979."

In 1982,, Vermont. Ynkee operated under the conditions of its NPDES permit in the open cycle modes of condenser cooling from.'

January 1 through:.May15 and October 16 through December 31.

Operation. in this mode is permitted in the period October 15 through May. 15 under thermal effluent limitations set forth in the permit.

These criteria, which define the maximum allowable impact on the Connecticut River of Vermont Yankee's discharge of heated condenser cooling water, are as.follow:-

A.

The temperature at Monitor 3 during open cycle operation shall not exceed 65OF; B.

The rate of change of temperature at Monitor 3 shall not exceed 50F per hour; and C.

The increase in temperature above ambient at Monitor 3 shall not exceed 13.4°F.

The temperature records at Station 7 and 3 show that these thermal limitations were'not exceeded in 1982.

The maximum hourly average temperature observed at Monitor 3 in'the period V

January 1 to May 15 and.October 16 to December 31 was 58.5 0 F on October 25.

The maximum rate of change of temperature at Monitor 3, the difference between successive hourly average*:temperatures there, was +3.2 0 F/hour, on March 8.

The largest rate of temperature decrease was -2.9 0 F/hour, on December 13.

Tabulations of the hourly rates of change in Monitor 3 temperatures during the periods of NPDES open cycle operation are.given-in Table 3.3.

These data are summarized as a frequency distribution in Table 3A4.

The mode, the median,-and the mean of these data were all O.00 F.

No direct measure of ambient temperature at Monitor 3 can be made at times when Vermont Yankee is discharging heated cooling water'into the rivet upstream of the monitoring station.

But calculations of temperature differences between Monitor 3, down-stream of Vermonot Yankee, and Monitor 7, upstream of the plant, give an indication of the impact of Vermont Yankee's discharge of Connecticut River temperature.

Tabulations of these differences f or the period of Vermont Yankee's.open cycle Operation under NPDES L

strictures in 1982 are shown in Table 3.5.

These data are reduced to a frequency distribution of temperature differences in Table 3.6.

The largest temperature difference in the 1982 data was +9.1 0 F at 1900 on October 29.

The mode and median of these data were each +i.9 0F and the mean difference in temperature between Station 3 and Station 7 was +2.46F.

WATER QUALITY STUDIES Dissolved oxygen concentration and pH,.in addition to temperature, have been monitored continuously by Honeywell W-20. Water Quality Water Collection Systems since 1968 at Station 3, downstream of Vermont Yankee, and since 1970 at Station 7, upstream of the plant.

Summaries of the dissolved oxygen and pH data collected in 1982 are shown in Table 4.1 for Station 3 and Table 4.2 for Station 7.

The dissolved oxygen data are reduced to daily means and.daily maxima and minima with times of occurrence; the pH data are shown as daily maxima and minima.

The tabulated dissolved oxygen and pH data of Tables 4.1 and..2 are presented graphically in Figures 4.1 through 4.4.

The shaded areas in those figures. show the largest maximum and smallest minimum observed in that.month in any one of the years of record prior to 1982.

The shaded areas in the dissolved oxygen graphs are. divided.by lines connecting the average. D.O.

for-each month calculated from the monthly means in all the previous years of observation.

No record monthly minimum D.O. concentrations were observed in 1982, but maxima were.recorded in March, April, and June that were greater than had been observed in earlier years of study.

At upstream Station 7, the April maximum of 14.9 mg/l exceeded the earlier.maximum of 14.5 mg/1 in 1979, and the June 1982 maximum of 10.0 mg/l was greater than the previously observed June maximum, 9.9 mg/1 in 1973.

At Monitor 3, downstream of Vermont Yankee, the March and-April maximum of 14.9 mg/l in..each month was 0.1 mg/l greater than the previous records-in those months, 14.8 mg/l in 1979.

At both monitoring locations the mean monthly D.O.

concentrations in November and December were lower than the average concentrations observed for those months in all the years of earlier studies.

The mean August D.O. concentra-tion at Station 3 was also lower than the 14 year mean of the earlier August data.

The April and the June means at both locations were higher than the means observed in any single year of prior study.

The Monitor 3 mean of 14.0 mg/1 in-April exceeded the highest April mean of 13.6 mg/l Observed in former years and the June mean of 9.6 mg/i was 0.i1mg/i greater than the previously observed June maximum there.

The Monitor 7 April mean was also 14.0 mg/l; the highest April mean observed there in prior years was 13.5 mg/i in 1978.

The June mean.of 9.0 mg/l was 0.1 mg/i greater than the highest mean June D.O. concentration previously at Monitor 7.

The pH minimum of 6.8 recorded at Monitor 3 in May was lower than the previous record minimum of 6.9, observed in 1978 and*1979.

All other pi inima and all maxima of 1982 were within the pH extremes that have been previously observed.

Grab samples for water quality analysis were collected on 4 dates in 1982 at the two monitor stations and from Vermont Yankee's cooling water discharge to the river.

These samples were analyzed for sixteen parameters by the procedures of Standard Methods for the'Examination of Water and Wastewater, 14th edition (APHA et al.

1976).

The analytical results are shown in Table 4.3.

With two exceptions, all concentrations observed for all parameters in 1982 at both Station 3 and Station 7 were within extremes that had been observed in samples of earlier years of study.

The exceptions were the total iron concentration, 0.08 mg/l, in the Monitor 3 sample of September 9 and the. chloride concentration, 11.3 mg/l, in the Monitor 7 sample of March 11.

The lowest concentration of iron observed at Monitor 3 in earlier years was 0.10 mg/i and the highest concentration of chloride found in earlier Monitor 7 samples was 10.8 mg/l.

On occasion, Vermont Yankee adds the following chemicals to its cooling water discharge to the Connecticut River:

sodium sulfate, as demineralizer regenerant; sodium hypochlorite, to control biological fouling of the condenser cooling system; and.sulfuric acid, for pH control.

The amounts of these chemicals discharged to the river are relatively small and not likely to significantly alter the river's water quality.

S

.However, to provide a quantitative basis for assessing the

impact of Vermont Yankee's operation on Connecticut River*

water quality, data on the concentrations of sodium ion, chloride ion, sulfate ion, and alkalinity concentrations were subjected.

" to statistical analysis.

The statistical methods used with these four.parameters have been detailed in Reports. IV and V of this-series (Aquatec 1975, 1976):.

Data collected for these four parameters at Stations 3 and 7. before Vermont Yankee began operation and during the'times of closed cycle operation through 1974 were combined and subjected to linear regression analysis.

These U1 analyses, using Station 7 concentrations as the independent variable, resulted in the statistics summarized in Table 4.4.

The.regression lines generated by these analyses are plotted as solid lines in Figure 4.5 for sodium ion, Figure 4.6 for sulfate ion, Figure 4.7 for chloride ion, and Figure 4.8 for.

alkalinity.

Each figure also shows, as dashed lines, the 95%

E confidence limits for station 3 concentrations predicted by the regression equation from new observations at Station 7.

These confidence limits were drawn from limits calculated for the minimum, mean, and maximum Station 7 concentrations used TABLE 4.4

SUMMARY

The applicable.

range of Station 7 concentrations for each regression equation is indicated on the figure by the vertical dashed lines at the minimum and maximum value of Station 7 concentrations used to develop the equation.

On each of the figures,. points for the data from samples

.collected in March, May, and November,' when Vermont Yankee was using open cycle condenser cooling,-are plotted as open circles.

Points for the data of September, when Vermont Yankee was, operating in the closed cycle cooling mode, are plotted in the figures as filled circles.

Fifteen of the plotted points lie within the applicable*

range of concentrations from which the regression lines were developed and are well within the 95% confidence limits for Station 3 concentrations predicted by the regression equations from the observed Station 7 concentrations.

The Station 7 chloride concentration in March (11.3 mg/1) is greater than the maximum Station.7 concentrationused in the regression analysis (10.2 mg/l), but the plotted point for the March chloride data would afall within the 95% confidence limits, of an ext.apolated regression line.

PLANKTON STUDIES Plankton samples were collected, as required by Vermont Yankee's NPDES permit, once each month in 1982 at the downstream and upstream water quality monitors, Stations 3 and 7 (Figure 5.1).. In addition, subsurface samples from the river at Vermont Yankee's condenser cooling water intake structure were collected on the nine dates in 1982 when entrainment studies were con-ducted.

The monitor samples, preserved in formalin, were collected by pumping river water through a No.

20 mesh Wisconsin plankton net.

Subsequently the sample volume was adjusted to 20 ml and.

an aliquot of the sample was examined in a Sedgewick-Rafter counting cell.

Plankton were identified to the lowest feasible taxonomic level and were counted as their normally occurring unit, i.e., phytoplankters as cells, colonies, or filaments and zooplankthrs as individuals or colonies.

The results of these analyses are presented below.

5.1 Phytoplankton Studies A summary of the counting results of the analysis of the 1982 phytoplankton samples is given in Table 5.1.

This table shows for each sample the dominant species observed, when one taxon was found in greater numbers than any other one, the con-centration in units per liter of that dominant organism, and the total count in units per liter of all algae in the sample.

The concentrations of phytoplankters found in the 1982 monitor samples are also shown graphically in Figures 5.2 and 5.3.

To permit ready comparison of the 1982 monitor sample data with that of earlier years, Figures 5,2 and 5.3 also carry plots of the monthly mean phytoplankton counts observed in the years r107-

1970-74, excluding data collected in 1974 during Vermont Yankee's open cycle testing.

Variability of algal concentrations about these means is indicated on the graphs by points which are two standard deviations greater than each monthly mean.

Algal concentrations in the net collections of 1982 were below-the mean concentrations observed in 1970-74 in all months-but July at Station 3.

The concentration at Station 7 in Jan-uary, 119 units/liter, was more than two standard deviations greater than the 1970-74 means for January at Station 7.

The algal counts at Station 7 in February and at Station 3 in July exceeded the means of 1970-74, but by less than two standard deviations.

In earlier reports of this series (Aquatec 1975, 1976),

a statistical analysis of the phytoplankton data collected prior to Vermont Yankee's operation and during closed cycle operation at the two monitor stations was presented.

This analysis.

developed linear regression equations which predictedMonitor 3 counts from three ranges of observed Monitor 7 counts.

Moni-.

tor 7 counts observed on all twelve sample dates in 1982 lie within the low range, 0-772 units per liter, for which the regression equation hasan intercept 6f 29.3,.a regression..

coefficient of 0:802, and a standard error of estimate of 193'.

comparison of the phyt6plankton counts observed at Monitor.3 in 1982.with counts predicted by this regression equation. from counts observed at Monitor 7 is shown in Table 5.2.

The only difference between the observed and the predicted concentrations

for Station 3 that exceeds two standard errors of estimate is that calculated fr6m the data of the July 19 samples.

Vermont Yankee had operated in the closed cycle condenser cooling mode for seven weeks prior to July 19.

-8 Forty-fivespecies of phytoplankton were identified in the twelve net samples at Stations 3 and 7 in 1982.

Small numbers of -twlve additional species were observed in the samples of river water collected at Vermont Yankee's intake structure during entrainment studies.ý A checklist of the net phytoplank-ton identified in these sampies is shown in Table 5.3.

Follow-incr the name of each taxon in the list are three numbers in parenthesis.

The first is the number of Monitor 3 samples in which the alga was observed; the second is the number of Monitor 7 samples in which it was found; the third is the number of entrainment sample dates on Which the taxon was found in a river intake sample.

The average number of identified species found in the twelve upstream Station 7 samples of 1982 was 7.2; in the down-stream Station 3 samples, the mean number was 8.3.

The number per sample at Station 7 ranged from only 1 identified species in April to 15 in the November sample.

At Station 3, the largest number of identified species was 15, in the samples of July and

-113-

September; the smallest number was 5,. in the.samples of Jan-uary, February, and December.

-In all earlier years of Vermont Yankee studies species of diatoms have been the predominant type of algae observed in the monitor samples collected by plankton net.

This was the case in 1982 also.

Diatoms constituted 50% or more of all the Moni-tor 7-samples, all the Monitor 3 samples except that of January.,

and all nine of the sets of entrainment intake samples.

A sum-mary of the percentages of diatoms, flagellates, green, and blue-green algae found in these 1982 net phytoplankton samples is given in Table 5.4.

Melosira italica and Melosira varians, and Tabellaria.fenestrata.

Melosira italica was found in all but 3 of the 24 monitor samples*

and in all 9 of the intake samples.

The more common flagellates were again Dinobryon spp. and the more frequently observed green algae were Pediastrum spp., particularly Pediastrum simplex.

Species of the blue-green algae Oscillatoria were found in 50%

5.2 Zooplankton Studies The results of the analysis of zooplankton samples collect-ed in 1982 at the two monitor stations and at VermonE Yankee's intake structure are summarized in Table 5.5 and in Figures 5.4 and 5..5.

Table 5.5 shows the concentration,. in units per liter, of zooplankters observed in each sample and the name and concen-tration of the predominant taxon in the sample, when one taxon was observed in greater concentration than any other.

In-the figures, total zooplankton counts observed in 1982 at the two monitor stations are plotted, along with monthly mean counts ob-served at these stations in-the years 1970-74, excluding times of open cycle testing.

To show variability about the means, the figures also carry plots of the means plus. two standard devia-tions.

Zooplankton concentrations in the monitor samples were relatively low throughout the year 1982.

In all months at both

-monitor stations the zooplankton counts were less than the 1970-74 means for the corresponding months.

Statistical analysis of zooplankton data collected at the two monitor stations in the years 1970-7.4, jprior to Vermont Yan-kee's operation and during closed cycle operation, has provided a basis for comparison of zooplankton counts observed at Monitor 3,

downstream of Vermont Yankee, with counts predicted from the IN zooplankton concentrations observed at Monitor 7 upstream.

This analysis, analogous to that used for phytoplankton, resulted in a linear regression equation relating Monitor 3 count, as depen-dent variable, to the observed Monitor 7 count.

For Monitor 7 counts ranging from 0.5 to 418.5, the equation has a regression coefficient of 0.918, an intercept of 15.7, and a standard error of estimate Of 83.8.

A comparison of the zooplankton concentra-tions observed in 1982 at Monitor 3 with those predicted by this equation is given in Table 5.6.

All differences between the observed and the predicted concentrations for Station 3 are less than two standard errors of estimate (167.6).

Organisms observed in entrainment samples collected from the river at Vermont Yankee's intake structure are included,

also, The three numbers in parenthesis following the name of each taxon. in the list are:

the number of Station 3 Monitor samples, of 12; the number of Station 7 MonitOr samples, of 12; and the number of entrainment intake samples, of 9, in which the taxon was observed.

Of the-46 taxa listed, 11 were observed only in entrainment intake samples, 6 only in Monitor 3 samples, and 8 taxa were found.only in the Monitor 7 samples.

The number of taxa observed in the Monitor 3 samples ranged from 1 in April to.9 in July; the average number of taxa in the twelve samples was 4.4.

The mean number of taxa found in the twelve. Monitor 7 samples was 4.7.

The largest number found was 10 in the October sample; the smallest number, 2, was ob-served in the samples of February through April.

Relatively large percentages of the organisms observed in samples of fall and winter were protozoans; particularly

4 L

-122-

Vorticella sp.

Copepods were less comdmonly observed than in some prior years, but were found in monitor samples of May through December and in 6 of the 9 intake samples collected rduring entrainment studies.

As has been found in all earlier years of zooplankton studies, rotifers *were the dominant.group of organisms in the majority of the samples'.

They constituted at least 50% of the zooplankters. found in 11 of the Station 3 samples, 8 of the Sta-

tion 7 samples, and 7 of the 9 entrainment samples.

The more commonly observed rotifers were Keratella cochlearis., Ploesoma sp.,

14 Synchaeta sp., and Philodina sp., which was found in 18 of the 24 monitor samples.

6. ENTRAINMENT STUDIES To assess the impact of entrainment.on phytoplankton and zooplankton in Vermont Yankee's condenser cooling water,.,'ine sets of condenser cooling water intake and discharge samples Were collected in 1982 at times when Vermont Yankee was utiliz-ing open cycle condenser cooling.

Eight were collected during times of Vermont Yankee's open cycle operation under the condi-tions of its NPDES permit.

The sample of October 7 was coilect-.

ed during the:..September 15 to October 15 operation in hybrid/

open cycle.6peration during the special study program termed Project SAVE.

For each sample,.40 liters of water, collected, by bucket, were poured through a No.

20 mesh plankton net.

A portion of the fresh. sample concentrate was examined within the hour to determine the identity'and *relative numbers of living.and dead organisms.

Z6oplankters were tabulated as living if they were observed to move. or showed internal movement within oneminute.

Phytoplankters were listed as living if they had normal pigmenta-tion and no.signs of plasmolysis.

The remaining portion of each sample was preserved with formalin for subsequent identi-fication and enumeration of the organisms present.

The taxa of phytoplankton and zooplankton found in the en-

trainment.intake samples in 1982 are indicated in the two check-

lists, Tables 5.3 and 5.7, of the previous section of this re-.

port.

In those lists,*the third number in parenthesis after each taxon is the number of sample dates, of a total.of 9, on which the taxon Was observed in an intake sample.

In general, the same taxa were observed in discharge samples as were found in river samples.

Twelve algal genera, however, were observed in discharge samples in 1982 that were not found in the intake

-127-

samples.

Of these twelve, three were diatoms, two were flag-ellates, five were green algae, and two were blue-greens.

Two genera of zooplanktoni Conochiloides and Bosmina, were found in

discharge samples, but not in intake samples.

The counting results of the analysis of the. fresh and pre-served entrainment samples are summarized in Table 6.1.

The-data of Table 61i have been used to calculate the percent changes in live plankton concentrations between intake and dis-charge samples shown in Table 6.2..

The impact of Vermont Yankee's entrainment of plankton on the river's concentration of live plankton is dependent upon the proportion of river flow, QR, which is utilized as conden-ser.cooling water.

During: open Cycleoperation, plant discharge flow rate, *Q, equals the rate of intake from the river, thus percent change of plankton concentration in the mixed.river is the percent change through the plant, Table 6.2, multiplied by the ratio of QD to QR" Calculations of the percent changes in

-river plankton concentrations due to entrainment on the 9 study dates of 1982 are shown in Table 6.3.

These calculations assume uniform distribution of river plankton at the intake structure and complete mixing of plant discharge into the river.

All calculated percentage decreases in river plankton con-W, centrations were less than 10%. Higher concentrations of living organisms in discharge samples than in intake samples were found on 6 of the 9 dates for phytoplankton and on 4 of the 9 dates for zooplankton.

Such increases in live plankton concentration, which have been observed in all prior years of study are attributable to the sloughing off into Vermont Yan-kee's circulating cooling water of algal growth attached to the walls of the cooling water system, growth that supports a community of microinvertebrates.

BENTHIC FAUNA STUDIES In compliance with the conditions of Vermont Yankee's NPDES permit, samples of Connecticut River benthos were collected by Ekman dredge and Henson trap at four sample stations shown int Figure 7.1.

Ekman dredge samples were collected monthly, from May through November, at each of the four stations.

Each Ekman dredge.sample consisted of.the organisms collected in 30 dredge hauls, 10 from each quarter point of the river, except that high river flows in May precluded collection of the 10 mid-river hauls at Station 3.

Henshn traps', wire cages filled with 2 to 3 inch diameter rocks, were set at each location in May, July, and Sep-:

tember and left in place'for.7.to 11 weeks.

The traps set at Station 3 in May and at Station 5 in July were vandalized before retrieval.

The.material collected by either sample method was.washed

through a.set of standard sieves and organisms and debris retain-*

ed by a No.

30 mesh sieve were preserved in 70% alcohol for sub-sequent analysis.

Identification was made to the lowest practi-cable taxonomic level, usually to genus.

A list of the benthic fauna found in these 1982 samples is given in Table 7.1 at the end of this section of the report.

The number of samples in which a listed taxon was found is shown in the table for eachsampling technique at each station.

Excluding the organisms listed as indeterminate that are not known positively to be different from other identified taxa, 145 taxa were found in the 1982 samples.

Fifty-six taxa were observed in the Station 2 samples, 57 in the Station 3 samples, 77 in the Station 4 samples, and 85 taxa were found in the samples at Sta-tion 5.

Of the 120 genera found in the 1982 samples, 73 were.

observed in the 10 Henson trap samples, and 99 were found in the

-Fifty-two geneia were collected-by both sampling techniques, 21 were observed only in the Henson trap collections, and 47 were found only in the Ekman dredge samples.

The number of samples collected by Ekman dredge in 1982 was comparable to the numbers collected at Stations 2 through 5 in the years-1969 and 1977-81.

A comparison of the number of genera collected by. Ekman dredge in these years with the results of the 1982.collections is shown in Table 7.2.

8/18 8/20 6/14 7/28 7/25 7/44 7/56 The number of genera observed in 1982 was greater at Stations 3,

4, and 5 than in earlier years.

The number observed in 1982 at Station 2 was only one less than the 40 genera observed there-in the 1981 samples.

The results of the analysis of the 1982 benthic fauna samples are summarized in Table 7.3.

The summary shows, for each sample, the number of organisms and taxa observed and lists the predominant type of benthos in the sample and the percentage of that form in the sample.

A diversity index is also tabulated for each sample.

the index was calculated with the following equation:

N (NloglO N -

E ni loglo ni) where C is a constant which converts logarithms from base 10 to

-135-

base 2; N is the number of organis ms; and ni.is the number of organisms in the ith taxon.

Chironomid larvae were the predominant organisms in 18 of

the 38 samples.

They were relatively more numerous in the samples collected upstream of Vernon Dam than in the samples of Stations 2 and 3, downstream of the dam.- At Station 5, chironornids were the

predominant form observed in.8 of the 9 samples collected; at Station 4, in 7 of the' 10 samples.

Caddis fly larvae were the more numerous forms.in 6 downstream samples., but in only one up-stream sample, the Henson trap collection at Station 4 in November..

Cladocerans predominated in downstream samples of August and Sep-tember' and planarians and amnicolid snails appeared as the dominant forms in some.fall samples at all stations.

FISH-STUDIES 8.1 -Fish Impingement Studies During all five phases of the special open cycle testing conducted in the years 1974-1978, fish impinged on Vermont Yan-kee's traveling screens at the intake structure were collected each day and identified, counted, weighed, and measured.

The results of these studies, summarized in the Phase V report (Aquatec 1979), provided the basis for the schedule of impinge-ment studies, set forth in Vermont Yankee's current NPDES per-mit, to be conducted during open cyCle operation.

This schedule requires a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months sample 3 times per week in October and the period April 16 through May 15, one time a week in November and from March 1 through April 15, and one 24.hour sample per month in December, January, and February.

Impingement studies during Vermont Yankee's 1982 open cycle operation under the conditions of the NPDES permit were conducted in accordance with this.

schedule. -Additional impingement collections were made in the other five months of 1982 as a part of the special Project SAVE program of studies.

A.sunmary of the weight ektremes and the extremes in*tbtal length of the fish species observed in all the impingement studies in 1982,. during both open and closed cycle operation, is given in Table 8.1. In Table 8.2, the numbers and total weight in grams of each impinged species are shown for each month of the year.

The fish species are listed in order of the decreasing number of the species impinged in all months of 1982.

Table 8.2 also shows for each month the mean number of fish impinged per test day in 1982.

At the bottom of the table are listed, for the months January through May and October

through December, the daily means and standard deviations, for both number and weight of fish impinged, that were observed in those months in the five phases of the open cycle test program conducted in the years 1974-78.

The mean number and weight impinged per test day in these months of 1982 were all within two standard deviations of the means observed in 1974-78.

A brief study of impingement was conducted in September 1976, during the Phase IV open cycle testing, The mean daily impinge-ment rates observed in 17 days of testing then were 7.1 fish and 35.2 grams, with standard deviations of 7.0 fish and 29.3 grams.

The impingement rate in September 1982 was much greater than this.

But, as already noted, the existing data base for*September is limited to 17 days of testing inma single year.

Data for the months January through May and October through December were collected in i974-78 in 3 to 5 different years and 66 to 150 days.

During June, July, and August, 1982, when Vermont Yankee was operating in the closed cycle mode of condenser cooling, 7 fish weighing 121.9 grams were impinged on 32 test days; the daily-means were 0.2 fish and 3.8 grams.

During the other nine months, when condenser cooling was open or hybrid mode, the impinged means per test day were 25 fish and 192:grams.

The means for the five phases of open cycle testing in 1974-78 were 23 fish and 240 grams.

One Atlantic salmon was impinged in May during one of the test days.

An additional salmon (36 grams, T.L.=170 mm)Was found on the traveling screens on 5 May 1982 when the screens were being backwashed in preparation for the collection of a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months sample.

One American shad was impinged in October..

8.2 Resident Finfish Studies A total of 8519 fish were collected in 1982 at Vermont Yankee Sample Stations 2, 3,

4, 5, and 8.

The locations of these stations are shown in Figure 8.1.

The fish were taken in 350 collections by four capture methods-trap net, gill

net,

seine haul, and electrofishing.

The collected fish were iden-tified and their weight and total length were usually measured and recorded.

In some instances, however, complete and reliable statistics on weight and length were not 6btained for each' specimen.

Occasionally a fish escaped before being weighed or measured.

Some white perch captured for the Project SAVE sur-..

vival studies were not weighed and measured, in order to mini-...

mize trauma to the fish before.placing them in holding cages.

The statistics presented in the following tables include only the fish for which weight and length data were collected.

A :summary, by station and capture method, of the fishing effort and the numbers and weight of fish collected in 1982 is shown in Table 8.3.

The data of the 1982 fish collections are summarized by species in Tables 8.4, 8.5, and 8.6.

Table 8.4 shows for all collections in 1982 the number, the-total weight, and the extremes in-weight and total length observed for each species,.

Table 8.5 summarizes-by sample station, capture method, and number of collections in which the species was taken-the numbers and total weights of the species captured north of Ver-non Dam.

Table 8.6 summarizes these data for the fish collected south of Vernon Dam.

Frequency distributions by total length for nine species are shown in Table 8.7.

Twenty-six species of fish were collected in 1982.

Four species-northern pike, Atlantic salmon, fallfish, and black crappie-were found only in the collections south of Vernon Dim; three species-common shiner, silvery minnow, and tessel-lated darter--were captured only-in collections north of the dam.

Only.one specimen of northern pike has been captured in prior years of Vermont Yankee fish studies.

That fish, weigh-ing 400 grams with a total length of 400 mm, was collected in September 1980 in an experimental gill net set near Stebbin

-158-

Island, about 1.25 miles downstream from Vernon Dam.

Blueback herring and American-shad, first collected in the Vermont Yankee fish studies in 1981, were.observed in.1982 also.

These species were introduced into the Vernon area in releases there of Ameri-

.can shad conducted as part of the continuing effort to restore breeding populations of anadromous fish to the Connecticut River.

One Atlantic salmon was captured in May in a trap net set south of Vernon Dam.

The species compositions, by weight and by numberi of the 1982 collections are graphed in Figures 8.2 and 8.3.

These compositions are reduced to a percentage basis and shown in Figures 8.4 and 8.5, along with percentage compositions of earlier surveys to permit comparison with previous studies.

All percentages by weight in the 1982 study were within extremes that had been 'observed in earlier.surveys, and the per-centages by number were' within extremes previously observed', with the exception of 'that of yellow perch.

The number of yellow perch-captured in 1982 constituted 22..5% of the total catch.

This exceeded the previous maximum of 17.6.% in 1981..

In the cdllections downstream of Vernon Dam, rock bass were 23.5% of the total number of.fish and white sucker'45.;3% of the-total weight in the 1982 catch.

Upstream of Vernon Dam, yellow perch constituted the largest percentage by number, 26.1%,

and the greatest proportion of the biomass was made up of carp, 25.7%

of the total weight of the catch.

Scale samples for age determination were taken from white perch, yellow perch,. walleye, and 'smallmouth bass collected in 1982 that had a total length 'of more than 50 mm.

The results of the reading of these scales, along with the age-growth data collected in years prior to Vermont Yankee's operation' with open cycle cooling, are shwon in Tables 8.8 through 8.11.

The data on number of annuli and mean total length from these tables are shown graphically in Figures 8.6 through 8.9.

-159-

For.white perch and yellow perch, the age-growth curves

.of the specimens collected north of Vernon Dam do not differ greatly from those of the years 1969-73.

However, the data for these species collected south of the dam appear to indicate an enhanced growth rate relative to that observed in the 1969-73 survey..

An increase in growth rate is suggested also in the walleye and smallmouth bass data 6f 1982, both north and south of Vernon Dam.

This indication of an increase in growth rate for these species was observed also in the walleye data of the previous five years and in the smallmouth bass data of 1981.

The possi-bility that the rate of growth of some fish species has changed.

significantly in recent years will be investigated further in 1983...

Scale samples were collected also from 128 largemouth bass in 1982.

The humber of this species captured in the years 1969-73 was small so no age-growth data from those years is available for comparison with that of 1982.

The results of the counting of annuli on the scales collected in 1982 are shown 'in Table 8.12.
