-s 2.0 LIMITING CONDITIONS FOR OPERATION 2.1 Thermal 2.1.1 Maximum AT Across Condenser 4

Objective To limit thermal stress to the aquatic ecosystem by limiting the maximum AT across the condenser during operation.

Specification:

a.

The maximum differential temperature across the condenser shall not exceed 15*F during normal operation with all four circulating water pumps in operation.

b.

If one or two circulating water pumps are out of service at any given time the maximum condenser AT shall not exceed 30*F; and Specification 2.1.2 of this Appendix shall be met.

Monitoring Requirement The temperature differential across the condenser shall be monitored every hour utilizing the computer output of the condenser inlet and O'

outlet temperature measurements. The range of these measurements shall be 0-150*F and their accuracy shall be 10.5%.

If the plant computer is inoperable, the condenser inlet and outlet temperatures shall be monitored every two hours utilizing the con-denser temperature recorder with a 0-150*F range and 10.5% accuracy.

Bases Maximum AT's of 15*F with 4 circulating water pumps operating

(%1700 cfs flow) and 30*F with 2 circulating water pumps operating will insure that the limits of the applicable water quality criteria will not be exceeded. The difference in temperature readings of the RTD's at the inlet and outlet of the condensers provides the AT across the condensers.

Specification 2.1.1.b allows maintenance to be performed on circulating water pumps when the Dardanelle Reservoir ambient temperature is such that Specification 2.1.2 will not be exceeded. Hydraulic model studies have shown that a 30*F AT at 850 cfs circulating waterflow will not result in adverse changes in the Dardanelle Reservoir isotherms when (w

i a

2-2 compared to the isotheras resulting from a 15*F AT at 1700 cfs except on the surface of the discharge embayment.

2.1.2 Maximum Discharge Temperature Objective To limit thermal stress to the aquatic ecosystem by limiting the plant's marinnun discharge water temperature.

Specification The condenser discharge water temperature shall not exceed 105*F for more than two consecutive hours.

If the water temperature exceeds 105'F for two hours an investigation of the situation will be undertaken and corrective action shall be taken to main-tain the discharge water temperature at 105'F or less. One such corrective acetan would be a reduction in the plant power level unless there is an emergency need for the lost power. This emergency need would exist when a reduction in power would mean cutting off firm customers.

If monitoring (see below) indicates that.the temperature at the mouth of the discharge embayment is < 105'F, the plant load will not be reduced.

Monitoring Requirements Condenser discharge water temperature shall be monitored every hour utilizing the average of the computer output of the condenser dis-charge RTD readings. The RID's have a 0-150*F range and an accuracy of 10.5%.

If the plant computer is inoperable, the condenser discharge water temperature shall be monitored every two hours utilizing the con-denser temperature recorder with a 0-150*F range and 0.5% accuracy.

If the condenser discharge water temperature exceeds 105'F, plant personnel will be dispatched to the mouth of the discharge embay-ment to monitor the exit temperature from the embayment. Monitoring of the embayment will continue every two hours as long as the con-denser outlet temperature remains at 105'F.

Bases The 105*F maximum discharge water temperature limit is set to assure that the Dardanelle Reservoir temperature does not exceed i

l 2-3 95'F as established by the applicable water quality criteria. The use of the condenser discharge RTD's provides the circulating water discharge temperature prior to mixing with the Dardanelle Reservoir water.

No credit was taken in the analyses and models of the circulating rater system for heat exchange within the discharge embayment even though it is expected that the water temperature will be reduced in the embayment. Thus, the average temperature should be 5105'F even when the temperature at the condenser discharge is greater.

2.1.3 Marimum BTU /hr Not applicable.

2.1.4 Rate of Change of Discharge Temperature Obj ective To avoid thermal stress to the aquatic ecosystem due to sudden changes in water temperature.

Specification In the event of a planned shutdown during the period November through April, the reactor power level shall be reduced to 0% at a rate such that the decrease in the condenser circulating water discharge temperature shall be 15*F/hr in order to. avoid any adverse thermal impact on the aquatic environment in the dis-charge embayment. As the reduction in power level is made, the number of operating circulating water pumps will be reduced.so as to limit the rate of decrease of the water temperature in the discharge embayment.

This.lmitation may be exceeded for brief periods as necessary to protect plant equipment and for certain safeguard operations which cannot be limited or negated by plant operation. These safeguard operations include automatic plant trips and compliance with safety-related technical specifications.

4 If after a few planned shutdowns at the specified rate, there are no detectable adverse effects on the discharge embayment environment, then future planned shutdowns may be conducted-at slightly higher rates. The required monitoring shall be O

l l

l

2-4 O

conducted until it is established that there is no adverse environmental impact associated with plant shutdowns conducted at the higher rate. If there is adverse environmental impact detected, then future planned shutdowns will be conducted at slightly slower rates until a shutdown rate where there is no detectable adverse environmental impact is determined.

Monitoring Requirement Condenser discharge water temperature will be monitored every hour during the power reduction utilizing the average of the computer output of the condenser discharge RTD readings. The RTD's have a 0-150*F range and an accuracy of 10.5%.

If the plant computer is inoperable, the condenser discharge water temperature shall be monitored at least once per hour during the power reduction utilizing the condenser temperature recorder which has a 0-150 *F range and a 0.5% accuracy.

The aquatic environment of the discharge embayment will be watched during and innediately after planned shutdowns in order to detect any adverse environmental impacts on the embayment, which might occur. A record of the observations made, rate of temperature change, and appropriate data shall be maintained.

Bases There has been no incidence of adverse environmentnl impact associated with any operating AP&L power' plant. There is also a lack of data or evidence which would support a limiting rate of change of temperature for the specific species that might inhabit the discharge embayment. In view of this, a conservative rate of change, <5*/hr, is specified.

It is also conservative because the actual rate of change of the discharge embayment will be slower than the rate of change of the circulating water system.

A reduction in circulating water flow will further decrease the rate of change of temperature in the discharge embayment.

2.1.5 Heat Treatment of Circulating Water System Not Applicable.

2.1.6 Deicing Operations Not Applicable.

I

2-5 s

2.2 Hydraulic 2.2.1 Intake Velocity A study will be undertaken as described in Section 4.1.2 to determine means of limiting fish impingement on the traveling water screens.

2.2.2 Discharac Velocity Not Applicable.

2.2.3 Flow Rate Restrictions Not Applicable.

2.2.4 Reservoir Drawdown Not Applicable.

2.3 Chemical Objective (General) r To protect tr.e local biota from lethal and sublethal effects of chemical

's discharges.

To assure that the most sensitive use of the receiving medium by human populations is protected. To minimize degradation of the quality of the receiving medium.

Specification (General)

All plant chemical discharges except that from the plant sanitary system shall be diluted by the plant circulating water during release to assure that the stated objective can be achieved.

2.3.1 Biocides Specification 3

a.

Chlorine (Circulating Water System)

Chlorination of condenser cooling water shall be intermittent (1 to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months each day or as may be necessary). Total available chlorine residual in the plant effluent shall be less than 0.1 mg/1.

If the total available chlorine residual in the discharge canal exceeds 0.1 mg/1, the chlorine feed rate shall be reduced to a rate at which this specification can be met.

g--

n w.

2-6 b.

Chlorine (Sanitary Waste System)

The hypochlorinator of the sewage-treatment system shall be maintained so that the free available chlorine residual of tha effluent shall not be greater than 0.1 mg/l at point of discharge to the embayment.

Monitoring Requirement a.

Chlorine (Circulating Water System)

Total available chlorine residual in the discharge canal shall be measured twice weekly during periods of chlorination.

Analyses will be made according to Table 2-1.

b.

Chlorine (Sanitary Waste System)

The sewage treatment effluent shall be checked monthly to ensure that the totalarailable chlorine racidual is not greater than 0.1 mg/l at point of discharge to the embayment.

Analysis will be made according to Table 2-1.

Bases The once-through circulating water flow taken from the Illinois Bayou arm of the Dardanelle Reservoir will pass through the

]

turbine condenser and will be discharged into an 80-acre embay-mert of the Reservoir.

Analysis of the chlorine demand of the Arkansas River water (i.e., the amount of chlorine required to oxidize substances in the water which reduce free chlorine) range from 2 to 4.q;/1 for a contact time of 30 riinutes. Reaction of chlorine with the untreated dilution water during the 4 t-5 minutes required for the flow to reach the embayment should _ educe the concentration of total available chlorine residual below 0.1 mg/l in the effluent.

It is estimated that Unit 1 chlorine usage will be 330,000 lb/ year.

l 2.3.2 Corrosion Inhibitors Specification There shall be no discharge of sodium nitrite to the plant discharge.

Oa

2-7 Monitoring Requirement The closed cooling water system 2f the plant shall be sampled weekly to ascertain whether sodium nitrite leakage from these systems has occurred.

Since sodium nitrite is subject to biodegradation, the test for nitrite nitrogen by Method 134 of Standard Methods will not conclusively establish whether leakage has occurred.

Specific conductance will also be measured using Method 154 of Standard Methods.

If nitrite nitrogen drops and specific conductance remains constant, l

no leakage will be presumed.

If both nitrite and conductivity are lower than the previous weekly test, immediate samples of discharge canal will be taken and a report made according to Specification 5.6.2.

4 Bases The closed cooling water systems are treated with sodium nitrite or sodium nitrite-based inhibitors. Under normal conditions, t %re will be no discharge of the sodium nitrite inhibitor to the plant discharge. Any leakage from these sytem would normally be un-detectable by sampling the discharge canal.

Sampling of individual closed water systems will be utilized for leak detection. Some inhibitor will be consumed in the protecting of the closed water h

systems.

It is estimat'ed that annual usage after initial charging d

of all systems will be 1500 lb/ year.

2.3.3 Suspended and Total Dissolved Solids Specification Both the conductivity and the turbidity of the plant effluent in discharge canal shall not be more than 10% greater than that of the water in the intake canal.

If the specific conductivity of the effluent in the discharge canal is found to be 10% g" eater than that of the water in the intake canal, the water in the discharge canal shall be resampled and analyzed for total dissolved solids (TDS).

If the TDS is increased more than that spec *.fied in Table 2-3 or if the turbidity of the effluent is found to be 10% greater than that of the intake water, then a report shall be made in accordance with Specification 5.6.2.

- ~

2-8 Monitoring Requirement The turbidity and conductivity of water in the intake and discharge canals shall be determined weekly during periods of discharge. Analyses shall be made according to Table 2-1.

Calibration curves relating conductivity to total dissolved solida shall be prepared monthly.

Bases The plant is not expected to significantly contribute to suspended or total dissolved solids. Turbidity and conductivity are accepted methods for determining these two parameters. A 10% increase resulting from plant effluents will be considered significant.

2.3.4 pH Specification The pH of all discharges to the Dardanelle Reservoir shall be between 6.0 and 9.0.

No single unit of discharge shall change the discharge canal water mere than 0.5 pH unit.

Monitoring Requirement The pH of the intake and discharge water shall be determined weekly during periods of discharge. Analysis shall be made according to Table 2-1.

2.3.5 Chemicals which Affect Water Quality Specification All chemical releases shall be maintained at the discharge canal to be less than those concentrations permitted by the Arkansas Department of Pollution Control and Ecology.

See Table 2-3.

Monitoring Requirement

/

Monitoring of the water in the intake and discharge canal will be done by weekly sampling and analysis for conductivity, chloride, hardness, phosphate, sulfate, turbidity, ammonia, iron, manganese, copper, silica, boron, hydrazine and pH.

Analyses will be made according co Table 2-1.

If, after the

1 2-9 concentrations present in the intake canal are subtracted from those present in the discharge canal, the concentration t

of any of the chemical parameters listed in this specification equal or exceed the concentrations listed in Table 2-3 or Specification 4.1.1, a report will be made in accordance with Specification 5.6. 2.

Bases Concentrations will be limited to meet requirements of the regulatory agencies concerned. Table 3-1 lists concentrations of chemicals expected to be discharged and their concentrations now present in the lake water.

2.4 Radioactive Discharge Objective _

To define the limits and conditions for the controlled release of radioactive effluents to the environs to ensure that these releases are as low as practicable. These releases should not result in radiation exposures in unrestricted areas greater than a few percent of natural background exposure. The release rate for all effluent discharges should be within the limits specified in 10 CFR Part 20.

To assure that the release of radioactive material to unrestricted areas meet the as-low-as-practicable concept, the following objectives apply:

O l

t

2-10 b.

Avuraged over a yearly interval, the release rate of I-131 and other particulate radioisotopes with half lives longer than eight days discharged from the plant should result in a dose in the unrestricted area of less than 15 mrem to the thyroid of a child through the grass-cow-milk chain.

2.4.1 Liquid Discharge Specification 1.

The rate of release of radioactive materials in liquid waste from the plant shall be controlled such that the instantaneous concentrations of radioactivity in liquid waste, upon release from the Restricted Area, do not exceed the values listed in 10 CFR 20, Appendix B, Table II, Column 2.

2.

If the release of radioactive materials in liquid effluents, when averaged over a calendar quarter, exceeds 2.5 curies, the Licensee shall:

Make an investigation to identify the causes for such a.

release rates; b.

Define and initiate a program of action to reduce such release rates to the design levels; and, Notify the Director, Directorate of Licensing within 30 c.

days, identifying the causes and deeribing the proposed program of action to reduce such release rates.

3.

The release rate of radioactive liquid effluents, excluding tritium and dissolved gases, shall not exceed 10 curies during any calendar quarter.

4.

During release of liquid radioactive vaste, the following con-citions shall be met:

2-11 i

i c.

The gross liquid waste activity and. flow rate shall be con-tinuously monitored and recorded during release. If this requirement cannot be met, continued release of liquid effluents shall be permitted only during the succeeding 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months provided that during this 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months period, two

independent samples of each tank shall be analyzed and two station personnel shall independently check valving prior to the discharge.

S.

Bases Releases' of radioactivity in liquid wastes within the design objective levels provide reasonable sasurance that the resulting D_

,._..y,

2-12 annual exposure from liquid wastes to the whole body or any organ of an indivi6d will not exceed 5 mrem per year. At the same time the Licensee is permitted the flexibility of operation, compatible with considerations of health and safety, t., assure that the public is provided a dependable source of power under unusual operating conditions which may temporarily result in releases higher than the design objective levels but still within the concentration limits specified in 10 CFR 20.

It is expected that using this operational flexibility under unusual operating conditions, the Licensee shall exert every effort to keep levels of radioactive materials as low as practicable and that annual releases will not exceed a small fraction of the annual average concentration limits specified in 10 CFR 20.

2.4.2 Caseous Discharge Specification 1.

Each monitor shall have an instrument channel test at least monthly and when discharging checked at least daily.

3.

During power operation, the condenser. vacuum pump discharge shall be continuously monitored for gross radiogas activity. The monitor shall not be inoperable for more than 7 days.

Whenever this monitor is inoperable, grab samples shall be taken and analyzed for gross radioactivity daily.

4.

Records shall be maintained and reports of the sampling and analysis results shall be submitted in accordance with Specifica-tion 5.6.

5.

The Waste Gas Decay Tank effluent monitor shall be tested prior to any release of radioactive gas from a decay tank and shall be calibrated at refueling intervals.

Bases:

It is expected that the releases of radioactive materials and gaseous wastes will be kept within the design objective levels and will not exceed on an instantaneous basis the dose rate limits specified in 10 CFR 20.

These levels provide reasonable assurance that the resulting annual exposure from noble gases to the whole body or any organ of an indivi-dual will not exceed 10 dem per year. At the same time the Licensee is permitted the flexibility of operation,' compatible with considera-tions of health and safety, to assure that the public is provided a dependable source of power under ususual operating conditions which may temporarily result in releases higher than the design objective levels but still within the concentration linits specified in 10 CFR 20.

It is expected that using this operational flexibility under unusual operating conditions, the Licensee shall exert every effort to keep levels of radioactive materials and gaseous wastes as low as practicable and that annual releases will not exceed a small fraction of the annual average concentration limits specified in 10 CFR 20.

These efforts shall include consideration of meteorological conditions during r leases.

(3) The detectability limits for activity analysis are baeed on the technical feasibility and on the potential significance in the environment of the quantities released.

For some nuclides, lower detection limits may be readily achievable and when nuclides are measured below the stated limits, they should also be reported.

J (4) For certain mixtures of gamma emitters, it may not be possible to measure radionuclides in concentrations

4.0 ENVIRONMENTAL SURVEILLANCE The surseillance program provides an examination of the aquatic eco-system of Lake Dardanelle in the vicinity of the plant as well as providing information on air, precipitation, ground water, soil, vege-tation and milk by radiological anelysis of samples in the area of the plant.

Since the aquatic ecosystem is the most likely to be affected both chemically and radiologically by plant operation, more emphasis has been placed on its surveillance. The waters of Lake Dardanelle are subjected to frequent chemical and radiological analyses. Organisms that live in the lake are studied biologically and subjected to radiological testing.

Studies are also made on the effects of impingement and entrainment of organisms in the cooling water system.

Provision is also made for temperature monitoring and controlling the rate of change in water temperature (Specification 2.1.4).

Results of the program, including the reports submitted in accordance with Specification 5.6, will be reviewed as specified in 5.3.

4.1 Nonradiological Environmental Surveillance 4.1.1 Abiotic a.

Aquatic 1

Lake water shall be sampled and analyzed as discussed below.

Table 4-6 summarizes the Lake water chemical sampling locations and schedule.

(1) Chlorine Objective:

J To determine the levels of enlorine concentration in station effluent water.

Specification-1 (a) Samples shall be taken twice weekly at the outlet of the discharge canal during chlorination periods and analyzed for chlorine and chloramines according to Table 2-1.

(See specification 2.3.1.a)

(b)

If total chlorine concentration in the discharge canal exceeds 0.1 mg/1, chlorine feed shall be reduced to a rate that results in a concentration in the discharge Pw l-I I

L

4-2 canal of less than 0.1 mg/l chlorine, and immediate sampling and chlorine analyses shall begin at Points 1, 18, 5, and 9 shown in Figure 4-3.

Reporting Requirements:

If total available chlorine residual is found to be 0.1 mg/l or above at any of the Points 1,18, 5, or 9 (shown on Figure 4-3), a report shall be made according to Specification 5.6.2.

Basec:

Chlorination of circulating cooling water shall be inter-mittent. Only one-half the condenser will be chlorinated per chlorination period. This-arrangement will provide both dilution and additional chlorfne demand to prevent excessive chlorine concentrations.

(2) Corrosion Inhibitors Objective:

To insure that the sodium nitrite based corrosion inhibitor used in the plant closed cooling water systems does not enter the Reservoir in such concentrations as to be harmful to aquatic biota.

Specifications:

~

(a) Samples shall be taken weekly from the intake and discharge canals and shall be analyzed for nitrite nitrogen according to Table 2-1.

Weekly samp,les shall be taken near or upstream of Point 20 (shown on Figure 4-3) coincident with sampling of intake and cloced cooling water samples and shall be analyzed for nitrite to determine if recirculation is occurring.

(b) Samples of the closed cooling water system shall be analyzed for inhibitor weekly ( :ording to the manufacturer's instructions to determine leakage from this system.

Reporting Requirements:

If discharge canal samples show a concentration of 0.005 mg/l of nitrite nitrogen or more after subtracting the concentration of nitrite nitrogen found in the intake canal or Point 20 samples (whichever is smaller), a report shall be made in accordance with Specification 5.6.2.

9

4-3 Q

Bases:

Under normal conditions, no sodium nitrite based corrosion i

inhibitor will be discharged to the Reservoir. Any abnormal i

leakage should be detected either in the discharge canal or by inhibitor analysis in the cooling system. Any leakage of sodium nitrite from the closed cooling water system will most probably find its way to the discharge canal. By sampling the intake canal and Point 20, a determination can be made of any nitrite present in the lake water from sources 1

other than plant operation. Specification 2.3.2 requires that no sodium nitrite be discharged. 0.005 mg/l is the detection i

limit for the nitrite nitrogen test.

(3) Dissolved Oxygen:

Objective:

To determine levels of dissolved oxygen concentration in the Reservoir water and the effects of station effluents thereon.

Specifications:

(a) Dissolved oxygen analysis shall be made at all sample points shown in Figure 4-3 on a monthly basis.

\\

(b) Analyses shall be made at the one and two foot depths and at five foot intervals thereafter to the bottom.

(c) Analysis shall be made using a polarographic membrane electrode with Yellow Springs Instruments Model 54 or equivalent. The instrument,shall be calibrated just prior to and inanediately following analyses made, according to Table 2-1.

R_eporting Requirements:

If dissolved oxygen is found to be less than 5 mg/l a report shall be made according to Specification 5.6. 2.

Bases:

Monthly analyses of dissolved oxygen will provide information on changes in concentration caused by naturally occurring seasonal changes as well as any changes brought about by station operation.

i l^

4-4 Sampling locations were chosen to provide information about i

the intake and discharge of station cooling water and its effect on dissolved oxygen in the Reservoir water. Arkansas Department of Pollution Control and Ecology Regulations require that dissolved oxygen not be less than 5 mg/l except when periodic lower values are of natural origin and therefore beyond the control of the water user.

(4)

Suspended and Total Dissolved Solids Objective:

To insure that suspended and total dissolved solids do not enter the Reservoir in such concentrations as to be harmful to aquatic biota.

Specification :

Samples of the intake and discharge canals shall be analyzed weekly for turbidity and specific conductance in accordance with the methods contained in Table 2-1.

At least two circulating water pumps shall be operating when samples are taken.

Reporting Requirements:

If the specific conductivity of the effluent in the discharge canal is found to be 10% ' greater than that of the water in the intake canal, the water in the discharge canal shall be resampled and analyzed for total dissolved solids (TDS).

If the TDS is increased more than that specified in Table 2-3 or if the turbidity oft.the effluent is found to be 10%

greater than that of the intake water, then a report shall be made in accordance with Specification 5.6.2.

Bases:

The plant is not expected to contribute any significant amounts of suspended solids. Dissolved solids will be diluted suffi-ciently to prevent their harmful concentration.

Turbidity and conductivity are accepted methods for determining j

suspended and dissolved solids, respectively, and a 10% increase in samples from the discharge compared to intake samples will be considered significant and may be attributed to plant opera-tion since plant discharges are directed to the discharge canal. Determinations can be made on the same samples taken weekly for other parameters.

9

4-5 (5)

Demineralizer Regeneration Wastes Objective:

l To insure that demineralizer regeneration wastes are not discharged in such concentrations as to be harmful to aquatic biota.

Specification:

(a) All demineralizer waste discharges shall be diluted by plant cooling water during release. No release of da=fneralizer waste shall be made without at least two Unit 1 cfrculating water pumps operating.

(b) The pH of discharges into the circulating water systems shall be maintained between 6.0 and 9.0.

Records shall be maintained on the pH of these discharges.

(c) Weekly analyses shall be made on samples taken during J

discharge from the intake canal and Point 20 shown on Figure 4-3 and the discharge canal for anunolia, hardness, iron, manganese, copper, chloride, sulfate, silica, boron and hydrazine by the methods given in Table 2-1.

Reporting Requirements:

If, after the concentrations of the parameters given in (c) above present in the intake canal or Point 20 are subtracted from their concentration in the discharge canal, the concen-tration of any of these parameters equal or exceed the concentrations listed below, a report shall be made in accordance w1th Specification 5.6.2.

Criteria reconumended by Arkansas Department of Pollution Control and Ecology.

- Criteria not established.

4-6 Bases:

Dilution of wastes by plant cooling water and weekly analyses will insure that recommended concentrations are not exceeded.

Sampling the intake canal and Point 20 will determine the concentrations of the listed parameters present in the lake water from sources other than plant operation. Dirferences in concentrations at Point 20 and the intake will determine if recirculation is occurring.

By subtracting these concen-trations frca concentrations in the discharge, the concentra-tions of listed parameters attributable to plant operation may be determined.

The parameters selected will be present in the plant discharge.

(6) Water Quality Objective:

To determine effects of plant operation on the physical and chemical parameters at selected points covered in the pre-operational background surveys.

Specification:

(a) Monthly samples will be taken at points shown on Figure 4-3 and subjected to chemical tests listed in Table 4-5.

(b) Physical measurements listed in Table 4-4 will be made monthly.

Reporting Requirements:

These measurements are made by personnel of the University of Arkansas at Little Rock and results will be reported'in the Semiannual Report of the UALR Project and will be included in reports filed under Specification 5.6.1.

Bases:

This program is essentially a continuation of the Dardanelle Background Survey begun by the University of Arkansas at Little Rock in 1968.

Aquatic (1) General Ecological Survey Obj ective:

1 The tutrpose of this survey is to provide information on,the co. ability of Arkansas Nuclear One (ANO) with the planktonic, nektonic, and benthic populations of the Dardanelle Reservoir.

Preoperational monitoring studies have been conducted since 1968, approximately five. years prior to operation of Unit 1.

These studies served as a basis for development of the

4-8 operational monitoring program described herein. The opera-tional monitoring shall begin with the operat. ion of Unit 1 and shall continue for five years after Unit 2 goes into operation.

The effects of plant operation shall be determined by comparison of ecological parameters studied in the preoperational program.

Survey Plan A map of the survey area showing sampling locations is pre-sented in Figure 4-3.

The type and frequency of field sampling shall be as presented in Table 4-3.

Specification (a)

Reporting Requirement This survey shall be carried out by:

(a) The University of Arkansas at Little Rock (UALR)

(b) Arkansas Polytechnic College, Russellville, Arkansas (c) Arkansas Power & Light Company, Annual meetings shall be held to discuss the results of the survey and, if necessary for better data, make modifications in the survey.

Reports shall be provided to AP&L at least every six months and copies shall be distributed to the Arkansas Department of Pollution Control and Ecologw, UALR, U. S. Corps of Engineers, U. S. Department of Interior (Bureau of Sports Fisheries and Wildlife), Arkansas Game and Fish Comunission, U. S. Environ-mental Protection Agency, U. S. Atomic Energy Commission, the Arkansas State Departner.c of Health, (Bureau of Environ-mental Health Services).

Bases:

The purpose of the proposed programs is to monitor possible influences by Arkansas Nuclear One on aquatic life in Lake Dardanelle. The programs are set up so as to sample various levels in the food chain to detect any abnormalities in number, distribution, size, or physical characteristics of the organisms.

Sample stations were selected at various points in the area around the site so that data could be collected and a range of plant influence could be determined. By selecting points at the intake and discharge coves, direct changes in the lake water can be observed. The points upstream and in the Illinois Bayou were selected to monitor upstre o aquatic life and plant influence. Stations were selected at scattered locations throughout the river channel so that ANO effects could be surveyed.

i

4-11

\\

Frequencies of sampling were chosen to obtain a trend of aquatic life in the area. Most fish surveys are set up to be conducted in the summer because the fish are more plentiful at this time of year.

It is felt that more frequent sampling of the organisms would produce repetitive data. However, less frequent sampling might yield erratic data from which no trend could be detected.

The data will be evaluated in relation to preoperational data obtained by AP&L, UALR, Ark, Tech., and various governmental ageccies.

By comparing preoperational data with postoperational data, changes in the environment can be detected. It is felt that in this way effects on the aquatic life by ANO can be monitored and controlled.

(2) Impingement of Organisms Objective:

The objective is to monitor those fish impinged on the intake screens to permit a quantitative assessment of impingement impacts.

Potential impacts of concern are effects on the fishery resource and dissolved oxygen resource of Lake Dardenelle.

If thes'e impacts are significant, appropriate Ih state and federal agencies responsible for fisheries shall

\\--

be consulted, and the necessary modifications to the intake syetam shall be implemented to satisfactorily reduce these impacts.

Specification Fish trapped on all of the intake screens will be sluiced to a collection basket where they will be identified, counted, and weighed following an eight (8) hour sampling period once every four days. Tabulatio'ns of this data will be made. If the number of fish impinged on any given sampling day exceeds 700 pounds, sub-sampling shall be used to determine certain parameters of interest regarding the impinged fish, such as i

length / weight meacurements.

If the projected fish kill on the screens exceeds 3000 lbs/ day based upon eight hour sampling, then a report will be made in accordance with Specification 5.6.2.

After the data are taken, the fish will be dumped into the trash grinder and discharged back into the outfall.

If this intended disposal method produces visible waste on the surface of the discharge embayment of Lake Dardenelle oxygen demand (BOD) with a commensurate decrease in dissolved oxygen (DO), then alternate disposal methods such as land fill disposal shall be used.

I l

t 4-12 Each day that the fish-kill on the screens exceeds 200 i

samples of water in the discharge embayment shall be taken during the grinding operation and analyzed for BOD and D0.

Reporting Requirements:

Weekly tabulations of data on species, quantity and weight of fish collected on intake screens will be reported on a semiannual basis.

(3) Entrainment of Plankton, Eggs and Larval Forms Objective:

The purpose of the entrainment survey is to determine the thermal and mechanical effects of the cooling water system on the various kinds and quantities of larvae, eggs, and plankton taken into the plant water system.

Specification:

Biological samples (organisms) of bottom samples and water samples were taken at 6-month intervals prior to plant operation and shall be taken at one-month intervals after operation at the intake j

and discharge locations. Pelagic larval fishes shall be l

sampled by trawling with a fish larval net also in the intake and discharge areas.

Feporting Requirement:

If the samples taken indicate a significant detrimental effect on these organisms such as radically increased radioactivity or drastically reduced population and these factors can be traced to ANO, whether due to pressure changes, thermal shock,

=dnanical stress or biocide exposure, appropriate action shall be taken to assure that these effects will not ultimately affect survival of the organism or its population. For addi-tional information on the monitoring of these organisms, see Specification 4.1.2, General Ecological Survey.

'V 4.2.10 Milk Sampling Samples of milk shall be collected monthly from the Kirkpatrick farm approximately eight miles west-northwest, from the Sims farm 4.8 miles northwest of the plant and from the Arkansas Tech. Herd 5 miles

{

east.

Samples shall be analyzed for Iodine-131, Strontium 89-90 and gamma emitting isotopes.

The area within five (5) miles of the plant shall be surveyed semi-annually for the locations of animals (cows, goats) producing milk for human consumption. The results of this survey shall be included in the Semiannual Operating Report required by Specification 5.6.1.

These locations shall be included in the milk sampling program as soon as the necessary arrangements can be made..The sampling fre-l quency for locations nearer than three (3) miles shall be every two weeks during the grazing season and locations nearer than 1.5 miles.shall be sampled weekly during the grazing season. Each sample shall be analyzed for I-131 as in Table 4-1, and monthly composites shall be analyzed for radiostrontium and gamma emitters.

4.2.11 Vegetation Sampling Grass and the leafy portions of other natural vegetation available at each of the air sampling stations shall be collected three times per 4O year (spring, summer, and fall). Food crops and pasturage in the vicinity of the plant also shall be collected as available at harvest time. Appropriate analyses of all samples shall be performad in accordance with accepted techniques and nuclides of interest as given in Table 4-1.

4.2.12 Soil Sampling Soil samples shall be collected semi-annually at the same locations as vegetation samples and analyzed for gross alpha and gross beta and gamma emitting isotopes as described in Table 4-1.

The Fall sample also shall be analyzed for Strontium 89-90.

Bases:

One of the limiting conditions for operation of Arkansas Nuclear One is restricting environmental effects due to plant operation in unre-stricted areas surrounding the plant site to within limits specified in AEC Regulations 10 CFR - Parts 20, 50, and 100.

This Radiological Monitoring Program includes measurements made on the air, water, and land environments to insure that these limits are observed.

6.0 SPECIAL SURVEILLANCE, RESEARCH, OR STUDY ACTIVITIES 6.1 Thermal plume mapping Objective:

To verify analytical and model studies of the thermal plume and to establish compliance with applicable water quality criteria under low-flow conditions in the Reservoir.

Program Specification:

A quasi-synoptic survey of the plant's thermal plume will be made by towing several fast response temperature sensors over a preplanned grid track.

Temperatures at each depth will be sampled sequentially at frequent intervals and the data will be automatically recorded (digitally) for processing. Wire angle and boat position will be measured and recorded throughout the survey so that the absolute position in space of each recorded temperature can be of such density that computer contouring will be used for information display.

(Provide more details)

This survey will be carried out once prior to plant operation to obtain background temperature data. When the plant has achieved full power operation, a series of 12 monthly surveys will be conducted to pe~s define the three dimensional aspects of the thermal discharge. Various

()

flow conditions will occur during the year allowing verification of compliance with applicable water quality criteria at several different flow conditions. Each continuous underway field survey will result in several thousand discrete data points. These data will be processed by computer to provide contours of temperature for each measured depth.

At the conclusion of the survey program, a final report will be pre-pared which will assess seasonal trends and correlate the measured temperatures and plume configurations with causative natural effects and plant operational data.

Reporting Requirements:

The.results of this survey shall be reported to the AEC upon the completion of the survey.

Bases:

This survey is necessary to establish compliance with applicable water quality criteria.

It will be conducted by a consultant firm competent in the measurement of thermal discharges from power plants.

This will insure that the survey data will be accurate and reliable in determining compliance with applicable water quality standards.

6.2 Fish Spawning Characteristics of Dardanelle Reservoir

~

Objective:

A program has been undertaken to determine the characteristics rf the Dardanelle Reservoir relative to fish spawning activities.

Program Specifications:

This program relates to the fish spawningg activities during the Spring of 1973 and shall determine the spawning fish populations and sizes in the Antake canal, discharge embayment, and one ref-erence area.

Samples shall be taken by fish nets selected to provide optimum spawning information. The positions for shore-line seining opera-tions will be chosen in areas characteristic of fish spawning.

In addition, the pelagic larval fishes will be sampled by trawling with a fish larval net.

Major spawning areas will be determined by sampling several points in each area.

Once the optimum sampling points have been located, consistent sampling will be done to provide as much practical information as possible.

Samples taken by net will be separated according to size, and reported by number under each size. Data will be prepared noting any I !

significant changes or unusual conditions.

Reporting Requirements:

The results of this survey shall be reported to the AEC upon its completion.

Bases:

This survey will provide information relative to the peak spawning period and the relative abundance of these fishes. This in turn will allow a more detailed evaluation of the data obtained from the operational fish monitoring program.
