Introduction This Annual Non-Radiological Operating Report is submitted to the Di rector of the Nuclear Regulatory Commission's Region ll. 0ffice as required In ' North Anna Power Station Environmental Technical Specifications (E.T.S.),

Units 1 and 2 (Docket Nos. 50-338 and 50-339), Section 5.6.1.1, Part A and Unit 2, Part II: Non-Radiological E.T.S., Section 5.4.1.

Included are summarizations and interpretations of the results of the non-radiological environmental surveillance programs and special studies conducted throughout the year 1980. The purpose of this annual report is to determine If there is-any harmful effect or evidence of irreversible damage on Lake Anna, Virginia A

and surrounding areas as a result of the operation of North Anna Power Station, 4

i Units 1 and 2.

When appropriate, comparisons are made with pre-operatioral studies, operational controls and previous environmental monitoring reports.

THERMAL MEASUREMENTS

(~)

METHODS AND MATERIALS V.

Two methods were employed to obtain temperature data from Lake Anna:

(1)

Fixed recorders (2) Multi-vessel / vehicle synoptic surveys ENDECO Type 109 Recording Thermographs (Environmental Devices Corporation - Marion, Massachusetts) were used in obtaining an hourly filmed record of water temperature at selected stations (Figure 3.1).

Instruments at stations 1, 3, 4, 5, and 6 were located at near surface (1 meter), mid-depth, and bottom; at stations 2, 7, 8, and 9 only near surface instruments were snployed.

Instrument maintenance and processing of data occurred every two i

mon ths.

l l

Whitney Models TC-5C and TC-5 Fleid Thermometers (Montedoro-Whitney O

Corporation - San Luis Obispo, California) were used for data collection during the quarterly synoptic temperature surveys. Hourly temperatures at each meter of depth were recorded at selected locations during daylight hours (Figure 3.2).

Results and Discussion ENDECO Instruments Means of daily high, mean, and low values recorded by ENDECO recorders are presented in Table 3.1 by month.

Station designations are as follows:

The letter T M, or 8 following the station designation code identifies

[)

the recorder placement as near surface, mid-depth, or bottom, respectively. Absence of the code letter Indicates a single near surface instrument at that location.

Means of daily extreme in surface temperatures ranged f rom 19C at the 651 Bridge in February to 34.5c at Station 7 (power station discharge) in August.

Steady-state surface temperatures (means of daily means) at Station 3 (near tne Dam) and Station 2 (power station intake) were 5 2c and 5 3c, respectively, in January (Isothermal conditions) ano 29 7C and 29.1C, respectively, in August.

Stratification occurred in the Lake between May and September, f

Synoptic Temperature Surveys Survey data are included for the months of February, May, August, and t

October.

October data are substituted for November due to an early cancellation l

of the November survey, resulting from inclement weather conditions.

I O

3.2 l

Sarface temperatures ranged from 3.0C at station M to 7.lc at 7

station C during the February survey (Table 3.2).

The coldest surface temperatures were recorded on the upper lake while stations in the area of the Dam exhibited slightly higher surface temperatures, as expected. An isothermal water column was present at many locations, but inverse stratification did occur at stations above station H.

Ice cover precluded any data collection at station N during the survey.

A range of surface temperatures from 18.6C (stations A and B) to 215C (station 0) was recorded during the May synoptic survey (Table 3.3).

Surface temperatureson the upper lake tended to be higher than those on the lower lake with all surface temperatures being within 3.0C of one another.

Stratification was commencing in the lake during May, however a strongly defined thermocline had not developed at all stations.

f A stratified water column was evident at many stations during the 4

August survey (Table 3.4).

Deeper stations on the lower lake showed a more obvious thermocline while shallower upper lake stations presented an erratic configuration or lacked a thermocline altogether.

When present, the thermocline generally commenced at 9-12 meters of depth, was of ten broken rather than uniform, ano in some cases extended to or near the lake bottom, precluaing a hypoilmnetic stratum. Surface temperatures ranged from 29 2C at station D to 319C at station G.

The water column was unstratified during the October survey (Table 3 5) as the lake approached expected winter Isothermal conditions. Upper lake stations were generally colder with respect to surface temperature than were those on the Icwer lake. A range of surface temperatures from 17.6C (s ration Q) to 22.3C (s tation A) was recorded during the survey.

INTRODUCTION

()

The impingement of fishes at North Anna is a result of cooling water being withdrawn from the lake during the operation of North Anna Po.ver Station. Fishes that are too large to pass through the intake traveling screens (9 5 mm mesh) are trapped against the screens as a result of circulating 3

water pump operation (15 m /sec./ pump).

To comply with E.T.S. Section 3.1.2.2, impingement samples were taken to determine the power station effect, if any, on the fish communities of Lake Anna, Virginia.

Methods and Materials All fish collected were washed from the traveling screens during 24-hour sampling periods. The sampling schedule for the first three weeks of a four-week cycle consisted of collecting two samples per week on non-l g-consecutive days. During the fourth week, a composite sample consisting b

of 12 continuous two-hour samples was taken. All operable screens were sampled when the accompanying circulating water pumps were in operation.

Each screen was washed for.a minimum of 10 minutes to assure that all fish were removed..The fish were washed into a catch basket at the end of a sluiceway and were removed and transported to the laboratory. Up to 50 individuals of 'each sps:ie were measured (total length in mm) and weighed (nearest 0.1 gm). Those fish numbering over 50 were enumerated and weighed in bulk.

I Water temperature, dissolved oxygen, weather conditions and number of operating screens and pumps were recorded during each sample.

Results The results of impingement sampling indicated that a total of 28,2c7 fishes representing 20 species was collected from the traveling screens V}

during 1980 (Table 4.1).

The annual catch was dominated by black crapple

(~

(Pomoxis nigromaculatus), yellow perch (Perca flavescens), and gizzard shad (Dorosoma cepedianum). These three species comprised 33.1%, 30.3%, and 4.1

24.0%, respectively, of the annual' catch. All remaining species represented

-<l3% of the total catch; Table'4.2 shows the total. number and weight (gms).of fish collected

]

for'each sample date. Black crappie (PN in table), yellow perch -(PF in table) and gizzard shad (DC In. table) are treated Individually; all others are

designated OT in the-table. Seasonal trends'are apparent with most species exhibiting peak impingement rates during the late winter-early spring months.

The impingement data from the composite samples are shown in Table 4.3 Diel patterns appeared to be present with greatust impingement occurring-during nocturnal sampling periods. The lowest impingement occurred generally between 1000 and 1400 hours0.0162 days 0.389 hours 0.00231 weeks 5.327e-4 months . On several occasions no fish were impinged during a'two-hour sampiing period.

Length frequencies of fishes collected are shown in Table 4.4.

The majority of the fish collected were between 50 and 200 mm in length,

~

with 82.2% of the total catch less than 200 mm in length.

Table 4.5 shows the estimated total number of fish impinged by season. Seasonal estimates were prepared by treating the total 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s

counts and the 12-two. hour counts as being from two different strata with different weights. The formulde for stratified random sampling with a finite population correction factor applied was taken from Cochran (1963).

Seasonal estimates were than computed by expanding the means by the number of days in the respective seasons. The estimated total number of fish impinged during 1980 was 111,464. Seasonal estimates were highest in the spring

'(56,112), with the fall showing the lowest Impingement (5,260).

Water temperature versus fish impinged is shown in Figure 4.1.

Tenperatures ranged from 2 9 C in February to 29 9 C in July. A general l

O encountered. ' impingement numbers substantially increased after a water V

temperature of 5.2 C was attained following the winter low.

Impingement numbers declined af ter the water temperature rose to approximate 1y' 13.0 C.

Discussion The estimated total number of fish impinged in 1980 (111,464) at the North Anna Power Station was considerably lower than in 1979 (613,116).

Gizzard shad showed the sharpest percentage decrease (94.6%) in terms of total estimated numbers between 1979 and 1980. The percentage of gizzard shad in the total catch fell from 89% in 1979 to 24% in 1980. The dominant length frequency class of 1979 for gizzard shad was 100 - 149 mm.

During 1980 sampling the station impinged only 2% of the 1979 total in this length class. This could indicate a poor year class for this size fish in 1980.

f Most of the gizza'rd shad collected in 1980 were in the 200-249 mm size class.

This size of shad are virtually useless as forage fish for the game species (McNeal,1977). Yellow perch and crapple, two game species, totaled 71,897 individuals in 1980, a reduction of 43 9% over last year. The total number of fish impinged at North Anna does not appear to be unusually high in ctxnparison with those reported at 33 other power stations located on inland waters (Freeman and Sharma, 1977).

Length frequency data showed 82.2% of fish collected were under 200 mm in length, in 1979, 89% of fish collected were under 200 mm.

This compares favorably with previous investigations (Nalco, Inc., 1976; Mather et al., 1977).

The temperature and impingement graph Indicated that impingement rates increased after a water temperature of 5.2 C was reached following the winter low. This phenomenon was previously shown in the data collected b

in 1979 v

introduction qQ 4

in accordance with E.T.S. Section 3 1.2.3, entrainment samples were collected during 1980 in order to determine the relative number and species composition of fish eggs and larvae entrained by circulating water pump operation at North Anna Power Station. The objective of this sampling program was to assess the ecological impact of entrainment on Lake Anna.

Methods and Materials Weekly samples were collected from March 6 to July 31, 1980. On each sample day, ichthyoplankton collections were made at 0600, 1200, 1800 and 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months using paired conical nets, 0.5 m x 1.5 m x 505 u mesh. The nets were placed in front of an intake forebay (Figure 5.1) for 10 minutes at each of three depths (surface, midwater and bottom). At the end of each ten minute period, the nets were retrieved and rinsed thoroughly.

Samples were returned to the laboratory for sorting and preservation in 3% buffered formalin. All fish eggs and larvae were identified to the lowest possible taxon.

The volume of water filtered was determir.ed using large-vaned, low velocity-sensitive digital flowmeters (General Oceanics Model 2030 MK ll).

Water temperature and dissolved oxygen were recorded at surface, midwater and bottom.

Results t

During the period March through July 1980, a total of 1278 fish l

larvae representing five species (Table 5.1) was collected on 22 sample dates.

Of the larvae collected (Table 5.2), 73.6% were gizzard shad (Dorosoma ceoedianum),

12.6% were sunfish (Lepomis spp.), 7.1% were white perch (Morone americana), and 1

c-o j"%()

5.6%'were yellow perch (Perca' flavescens).

Gizzard shad dominated collections from mid-May through mid-June, while Lepomis spp. were dominant during July.

yellow perch were collected during April and. white. perch were most abundant during late April'and early May.

BI'ack crapple (Pomoxis nigromaculatus) were represented by relatively few numbers and were collected during May and June.

Of the larvae collected during 1980, midwater samples included 40.7%

of the total and bottom samples accounted for 35 0% of the larvae collected (Table 5 3).

Gizzard shad and white perch were most abundant in midwater and bottom collections while,Lepomis spp., yellow perch and black crapple were collected primarily in surface samples.

As'shown by Table 5.4 gizzard shad and white perch were most abundant during the 2400 hour0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months collections while Lepomis spp. were collected primarily during the 1200 and 1800 hour0.0208 days 0.5 hours 0.00298 weeks 6.849e-4 months samples. Yellow perch and black crapple were collected in insufficient numbers to ascertain a distinct diel pattern.

Daily entrainment estimates were prepared treating depths as strata.

~ Stratum weights were equal and the finite correction factor was ignored 3

(Cochran,1963).

Daily density values (larvae /1000 m ) are multiplied by average volume pumped that sample day (Table 5.5).

Period estimates were computed using daily estimates and the number of days in each period. Variances for period estimates were taken as a weighted average of daily variances.

0 Totaling period estimates by species result in an estimate of 1.419 x 10 larvae entrained for March ' through July 1980 (Table 5.6).

During 1980 entrainment sampling, no fish eggs were collected. Most species of reproducing fish in Lake Anna produce demersal, adhesive eggs which greatly reduces potential entrainment (Lippson and Moran, 1974).

7 Discussion V

The total number.of larvae collected during the 1980 sampling period declined from 1979 values due to a substantial decrease in the number of gizzard shad larvae collected; however, there was an increase in the larvae collected for all other species during 1980. The large number of gizzard shad larvae collected in 1979 resulted from a successful spawn which is supporteo by the increase in standing crop estimates for gizzard shad f rom 86.8 Kg/ hectare in 1979 to 119.8 Kg/ hectare in 1980 (see Volume 2 of this report). The esti-5 mates of white perch larvae entrained have increased from 1978 (198 x 10 )

7 through 1980 (1.02 x 10 ) due to the growth of the Lake Anna white perch population as indicated by the increase in Kg/ hectare estimates from 1.29 in 1978 to 4.18 in 1980 (see Volume 2 of this report).

The estimate of Lepomis spp. larvae entrained increased in 1980; however, estimates of standing crop indicate that Lepomis spp. continue to comprise over 30% of ths Lake Anna fish population.

The vertical distribution pattern shown by 1980 data is consistent with that of previous years.

The increase in larvae collected during the 2400--

hour sample pdriod is probably related to greater net avoidance during daylight samples as demonstrated by numerous researchers (Ecological Analysts,1977).

Of the total larvae entrained (1.419 x 10 ) during the 1980 sample f

period, gizzard shad comprised 72.2%.

The gizzard shad is the dominant forage l

fish in Lake Anna and in view of standing crop estimates for gizzard shad (119.8 Kg/ hectare in 1980) and the high fecundity estimates for gizzard shad which range from 22,400 to 543,900 (Jones et al.,1978), the potential produc-tion of gizzard shad larvae should be sufficient to withstand the entrainment ef fects of North Anna Power Station.

If the total number of larvae entrained

/D V

. m

()

for all other species (3.84 x 10 ) is evaluated with respect to the potential larvae production of these species, no adverse impact would be expected.

Regardless of the source of a disturbance on fish populations, there exists some natural compensatory capacity within -that population.

Compensation is the capacity of a population to offset reductions in numbers caused by some disturbance such as ccmmercial or sport fisheries or impingement and entrain-ment (McFadden, 1977). Ricker (1954) stated that the removal of young fish (eggs, larvae and Juveniles) is at least partly balanced by the increased survival of the remaining fish.

It is possible that fish populations could withstand exploitation by power plants ar levels described in sustained commercial and sport fisheries (McFadden,1977). The natural compensation capacity of fish populations in Lake Anna would minimize the impact, if any, of entrainment by North Anna Power Station.

Morrisville, North Anna - Ladysmith, and North Anna - Midlothian 500 KV lines on August 22, 1980. A number of locations were recorded, from aerial patrol, where erosion was taking place on the North Anna - Midlothian line, and a few places on the North Anna - Ladysmith and the North Anna - Morrisville lines. The majority of the locations noted were caused by vehicle travel up and down the right of way. These areas were disced, ferti-lized, seeded, and mulched with additional straw bales being installed to prevent erosion.

Discharge numbers assigned for convenience

- Boron high due to maintenance activities.

- - Values include Baron discharged from Unit 1 Steam Generators 4.1.a.2 Type of Discharge - Amonia and Hydrazine

~

Discharges of Ammonia and Hydrazine to the aquatic environment are difficult to quantify. Since Hydrazine reacts with oxygen to give essentially amon'ia and since ammonia is also discharged to the atmosphere, the basis for discharge is an estimated maximum value based on specifications.

From WCAP 8113, Rev.1, January 1975. Figure 7-19 a pH of 9.0 corresponds to an amonia concentration 0.-25 PPM 3

Therefore:

i Estimated maximum blowdown for three steam generators =

105GPM x 60 Min /Hr. x 24 Hr./ day x 270 days = 4.08 x 107 gallons. l Pounds of Amonia = 8.337 x 10 6 x volume x Pounds of Amonia = 8.337 x 10-6 x 4.08 x 10gPM NHx0.35 S

Pounds of Amonia discharged per unit = 85 pounds as NH3 d

Pounds of Ammonia discharged for 1980 = 170 pounds as NH3 l

~~Dear Dr. Brehmer:~~
This letter is in regard to the fecal coliform data submitted in accordance witl Special Condition flu.r.ber 7 in NPDES Pernit flumber VA 0052451 Tor your, florth Anna facility. We have reviewed the infonnation__submi tted _ar.d see no_
reason to continue to monitor this parameter.
The amendment to the florth Anna Permit has been dolapd for s:ma time as. a.
result of our difference of opinion concerning the establishent'of limita-tions for outfall 009.
As you are aware, the effluent cedelines proroced in September 1980 do not address construction runoff. Wa vill therck,e incorocrate the TSS limitations of 60 mo/1 daily averaaf and 103 tr.g/l daily maxict.m as requested in your letter of 17 June 1980. We will forward the Feviac urait psrmit to E?A next week and anticipate sendinr; the $roft per-mit to you in December.
We have reviewed your letter of 30 September 1980 regarding the oil spill at the Bremo Bluff _ power _ station.
Our primary concern is that no r..4ditional oil be lost to the James River. As your twice weekly inspections of outfall 001 have indicated since mid spring, the oil seepage is no longer evident The monitoring wells have also shown little or no oil since they were'initi-ally drilled.
In lieu of written reports, we request that both the cooling water discharge outfall 001 end the monitoring wells continue to be inspected
.on a regular basis arid that we be notified of any increase in amount of oil at these locations. We are hopeful that the measures teken by the company during the past spring and surt.mcr will be sufficient to prevent any further loss of O
oli from the statics.

e-Also we have not received confinnation of the pubif e notice for the Bremo Bluff reissuance.
As you are aware, we cannot proceed with the reissuance of the pennit or the cancellation of the consent order, until we receive the certifir:ation of the public notice procedures.
Your prompt attention to this mattee will be appreciated.
Finally, the October DMR contained a violation of the maximm pH effluent limitation for outfall 004.
The DMR indicated a maximum value of 11.2 vs a pennitted 8.5.
The violation was attributed to a spill of sodium hydroxide on 10 October.
The spill was the result of the failure of a liquid level indicator serving a tank in the area of the demineralizer.
~
He do not anticipate the initiation of an enforcement action as a result of this violation, but as you are aware persistent violations of this or any permit condition mr, r.c.cessitate the involvement of the Bureau of Enforcement.
If you have any questions regarding any of the matters discussed herein,'please don't hesitate to contact me.
Sincerely, UIh O
