1.0 JA^roduction l This report presents an analysis of the results of the REMP conducted during 1994 for Union Electric Company, callaway Plant.

In accordance with federal and state regulations and the desire to maintain the quality of the local environment, UEC began its radiological monitoring program in April, 1982.

The objectives of the REMP are to monitor potential critical pathways of radioeffluent to man and determine the radiological impact on the environment caused by operation of Callaway Plant.

Callaway Plant consists of one 1239 MWe pressurized water reactor, which achieved initial criticality on October 2, 1984. The plant is located on a plateau approximately ten miles southeast of the City of Fulton in Callaway County, Missouri and approximately eighty miles west of the St. Louis metropolitan area. The Missouri River flows by the site in an easterly direction approximately five miles south of the site at its closest point.

I 2.0 Radiolocical Environment Monitorina Procram 2.1 Procram Desian The purpose of the operational REMP at Callaway Plant is to assess the impact of plant operation on the environment. For this purpose samples are collected from waterborne, airborne, ingestion and direct radiation pathways. Sampling media are selected which are likely to show effects of plant effluents and which are sensitive to changes in radioactivity levels. The types of sample media collected are: milk, surface water, groundwater, shoreline sediment, bottom sediment, soil, wetlands, fish, vegetation, airborne particulate, airborne radiciodine and direct radiation (TLD).

Samples are collected by Union Electric personnel and shipped to Teledyne Isotopes Midwest Laboratory (TIML) for analysis. TLD's are analyzed by Union Electric Personnel. The data obtained are reported monthly and summarized in the annual report.

Environmental sample locations are divided into two types, indicator and control. Indicator samples are those collected from locations which would be expected to manifest plant effects, if any. Control samples are

collected at locations which are expected to be unaffected by plant operation.

2.2 Procram Description Sample locations for the REMP are shown in Figures 1, 2 and 3. Table I describes the sample locations, direction and distance from the plant, which are control and which are indicator locations, and the types of samples collected at each location. Sample collection frequencies for each of the monitoring locations are given in Table II. The collections and analyses that comprise the program are described in the following pages.

Identification of sample type codes used in Table I are as follows:

Code Samole Collected AIO Air Iodine APT Air Particulate AQF Fish AQS Sediment FPL Leafy Green Vegetables IDM TLD MLK Milk SOL Soil i SWA Surface Water WWA Ground Water l 2.2.1 Waterborne Pathway l

Surface Water Monthly composite samples of surface water from the Missouri River are collected from one indicator .

, location (SO2) and from one control location (SO1).

l The samples are analyzed for tritium and by gamma spectrometry.

Ground Water Ground water samples are collected monthly from two on-site wells (F05 and F15) and one off-site well used for drinking water (D01). The on-site ground water samples are collected using a manual grab sampler which is lowered into the well. The off-site ground water sample is collected from a faucet after allowing the line to flush for two minutes. Ground water samples are analyzed for Tritium and gamma emitting nuclides.

Bottom Sediment Bottom sediment samples are collected semi-ant.ually from one indicator location (C) and one control location (A). The samples are taken from water at least 2 meters deep to prevent influence of bank l

erosion. A Ponar dredge is used to obtain the samples, all of which consist of the uppermost layer of sediment. Each sample is placed, without preservative,

( in a plastic bag and sealed. Bottom sediment samples r:a analyzed for gamma emitting isotopes.

Shoreline Sediment Shoreline sediment samples are collected semi-annually at the same locations as bottom sediment. The samples are collected within two feet of the waters edge and consist of 2 six inch diameter by two inch deep sediment plugs. Each sample is placed in a plastic bag and sealed. Shoreline sediment samples are analyzed for gamma emitting isotopes.

Wetlands Soil Wetlands Soil Samples are collected annually from 3 indicator locations (W2, W3, and W4) and one control location (W1). Two 6 inch square soil plugs consisting of the uppermost two-inch layer of soil are taken at each location. The samples are placed in plastic bags and sealed. Wetlands soil samples are analyzed for gross alpha, gross beta, and gamma emitting isotopes.

2.2.2 Airborne Pathway Airborne Particulates Airborne particulate samples are collected on a 47mm diameter glass fiber filter type A/E (99 percent removal efficiency at 1 micron particulate) at a volumetric rate of one and one half cubic feet per minute at five locations. The particulate filters are collected weekly and shipped to TIML for analyses. The filters are analyzed for gross beta activity approximately five days after collection to allow for decay of naturally-occurring short-lived radionuclides.

Quarterly composites of filters by location are gamma-scanned and analyzed for Strontium-89 and Strontium-90. Four of the five locations are indicator locations (A1, AB, A9, and B3) and one location is a r

' control location (A7). One of the indicators (A9) is located at the community with the highest D/Q.

Airborne Iodine Each air sampler is equipped with a charcoal cartridge in-line after the particulate ~ filter holder. The charcoal cartridge at each location.is collected at the same time as the particulate filter and analyzed for Iodine-131 within eight days after collection.

2.2.3 Incestion Pathway Milk

'Two gallon milk samples are collected semi-monthly during the pasture season (April through September) and monthly during the winter from one goat and one cow milk location near the Plant (M5 and M6) and one cow milk location away from the Plant (M7). Milk samples

!i are shipped in ice to be received by TIML within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of collection. Analyses for Iodine-131, elemental calcium, Strontium-89, Strontium-90, and gamma emitting nuclides are performed on all milk samples.

Fish The five most abundant recreational or commercial fish species are-collected semi-annually from one indicator location (C) and one control location (A). Fish samples are filleted and are analyzed for Strontium-89, Strontium-90 and gamma emitting isotopes.

Vecetation Monthly, during the growing season, green leafy I vegetation is collected from two indicator locations (V6 and V8) and from one control location (V3).

Vegetation samples consist of mustard greens, turnip >

greens, cabbage, lettuce, and spinach. The vegetation samples are analyzed for gross alpha, gross beta, Iodine-131, and by gamma spectrometry.

Soil once a year soil samples are collected from ten indicator locations (F1, F2, PR3, PR4, PRS, F6, PR7, F8, F9, and PR10) and one control location (V3). To ensure only the most recent deposition is sampled, the uppermost two-inch layer of soil is taken at each location. Samples consist of 2 six inch square soil plugs. The litter at the surface and the root mat is i considered part of the sample. The samples are placed  ;

in plastic bags and sealed. Each soil sample is l

analyzed for gross alpha, gross beta, and gamma emitting isotopes.

2.2.4 Direct Radiation 1

ThermoluEinescent Dosimetry Thermoluminescent Dosimetry (TLD) is employed to determine direct radiation levels in and around the Callaway site. Panasonic model UD-814 TLD's sealed in plastic bags are placed in polypropylene mesh cylindrical holders at fifty two locations and exchanged quarterly and annually. Fifty of the fifty-two locations are indicators (2 through 33 and 35 through 52) and two locations are controls (1 and 34).

2.3 Procram Execution The program was executed as described in the preceding section with the following exceptions; Surface Water

1. Sampler equipment malfunctions resulted in an inoperable upstream composite sampler (Sol) from 01/01/94 to 03/31/94.

2. The upstream composite sampler was taken out of service on 05/10/94 and remained out of service for the rest of the year because the upstream t

sampler was being influenced by the plant discharge. A design change to move the sampler intake upstream, out of the plant discharge

) influence, is being implemented and should be completed in 1995.

3. The downstream composite sampler was inoperable from 01/01/94 to 6/02/94 due to sampler equipment malfunction and damages aue to flooding of the Missouri River.

4. The downstream composite sampler was taken out of service from 09/09/94 to 10/13/94 to implement modification package 94-1030 to reduce the impact of Missouri River flooding on the sample location.

During functional testing the sample pump malfunctioned and the sampler remained out of

2.4 Analvtical Procedures Analytical procedures and counting methods employed by the contractor Laboratory follow those recommended by

• the U.S. Public Health Service publication, Radioassav l Procedures for Environmental Samples, January 1967; and  ;

the U.S. Atomic Energy Commission Health and Safety Laboratory, HASL Procedures Manual, (HASL-300), 1972.

A synopsis of the routinely used analytical procedures for sample analyses is presented below.

2.4.1 Airborne 2.4.1.1 Gross Beta The glass fiber filter type A/E (99 percent removal  ;

efficiency at 1 micron particulate), is placed into a stainless steel planchet and counted for gross beta radioactivity using a proportional counter.

2.4.1.2 Gamma SDectrometry Filters are composited according to location and -

counted using a germanium detector which is coupled to a computer based, multi-channel analyzer. The resulting spectrum is then analyzed by the computer and specific nuclides, if present, identified and quantified.

2.4.1.3 Strontium-89 and Strontium-90 The composited filters, with stable strontium and barium carriers added, are leached in nitric acid to bring deposits into solution. After filtration, filtrate is reduced in volume by evaporation. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from nitric acid, the nitrates are dissolved in acid again with l added yttrium carrier and are stored for ingrowth. The .

yttrium is precipitated as hydroxide and separated from l strontium with the strontium being in the supernate.  !

oxalate data. The Strontium-89 activity is determined ,

by subtracting the previously calculated Strontium-90 activity'from.the measured gross strontium activity calculated from the carbonate. .i 2.4.1.4 Iodine-131 j.

Each Charcoal cartridge is placed on.the germanium detector and counted. A peak of 0.36 MeV is used to i calculate the concentration at counting time. The I

equilibrium concentration at the-end of collection is then calculated. Decay correction for the time ,

interval between sample collection and counting is then l' made.

2.4.2 Direct Radiation

~

Direct radiation measurements are taken by UEC using' Thermoluminescent Dosimeters (TLD's). The UEC program employs the Panasonic Model UD-814 TLD and Model UD-710 automatic dosimeter reader. Each dosimeter consists of three elements of CaSO :Tm and one element of ,

Li B O : Cu. The dosimeders are sealed in a moisture rehfsfant plastic bag and placed inside a polypropylene mesh cylindrical holder in the environment.- After exposure in the environment the dosimeters are read and the exposure for the time period is determined from the CaSO :Tm elements. The Li B O Cu element is not used todbtermineexposuredurfnh7: routine' operations. (

2.4.3 Vecetation 2.4.3.1 Iodine-131 A suitable aliquot of wet (as received) sample is placed into a standard calibrated container and. counted using a germanium detector coupled to a computer based, multi-channel analyzer. A peak of 0.36 MeV is used to calculate the concentration at counting time. The equilibrium concentration at the end of collection is calculated by decay correcting for the time interval between sample collection and counting.

The resin is washed with Nacl and the iodine is eluted with sodium hypochlorite.- Iodine in the iodate form is reduced to I2 and the elemental iodine extracted into CCl # back-extracted into water, then precipitated as pa11adium iodide. The precipitate is counted for I-131 using a proportional' counter.

2.4.4.2 Strontium-89 and Strontium-90 One liter of milk containing strontium and barium carriers is passed through a cation-exchange resin column.

Strontium, barium and calcium are eluted from the cation-exchange resin with sodium chloride solution.

Following dilution of the eluate, the alkaline earths

) are precipitated as carbonates. The carbonates are then converted to nitrates, and strontium and barium nitrate are precipitated. The nitrate precipitate is dissolved, and barium is precipitated as the chromate, purified as the chloride, and counted for Barium-140 (if required). From the supernate, strontium is

) precipitated as the nitrate, dissolved in water and reprecipitated as strontium nitrate. The nitrate is converted to the carbonate, which is filtered, weighted to determine strontium carrier recovery, and counted for " total radiostrontium" using a proportional counter.

l After counting total radiostrontium the second time i after six to eight days, Sr-89 concentrations are calculated. If the Sr-89 concentration shows a 7- positive result, the precipitate is dissolved, yttrium

! carrier added and the sample is stored for six to eight days to allow for additional yttrium ingrowth. Yttrium l l

,During 1994 three modifications were~made'to the'

's monitoring program. .The first: modification was addition of-a new milk sampling location (M7) during the. month of May. This location. replaced the control.

sample location deleted in 1993.

[ The second change was the replacement of vegetation-sampling location V7 with new-location V8 forsthe 1994 collection period. The residence at' location V7 has been vacated..

The third change l-involved the relocation of surface water sample location Sol from the plant. intake structure to the upstream intake barge bumper. This L change wat initiated because the upstream sample location at the' intake structure.was being influenced-by the Plant discharge.

3.0 Isotonic Detection Limits and Activity Determinations A discussion of the-calculations used in determining detection limits and activity by the Contractor-Laboratory is found in Appendix C.

4.0 Ouality Control Procram To insure the validity of the data, the contractor laboratory maintains a quality control (QC) program which employs quality control checks, with documentation, of the analytical phase of its environmental monitoring studies.

The program is defined in the Quality Control Program, and procedures are specified in the QC Procedures Manual.

The QC Program includes laboratory procedures designed to prevent cross-contamination and ensure accuracy and precision of analyses. The quality control checks include blind samplas, duplicate samples, and spiked samples as necessary to verify laboratory analysis activities are being maintained at a high level of accuracy.

The Quality Control Program is in compliance with USNRC Regulatory Guide 4.15 and includes appropriate control charts with specified acceptance levels for instrument source checks, background, efficiency, etc. for counting equipment.

The Laboratory participates in the USEPA Interlaboratory Comparison Program (crosscheck program) by analyzing radioactive samples distributed for that purpose. The results of the crosscheck program are presented in Appendix B.

5.0 Data InterDretations In interpreting the data, effects due to the Callaway Plant must be distinguished from those due to other sources.

The principal interpretation method tsed in assessment of those effects is the indicator-control concept used in the design of the monitoring program. Most sample types are collected at both indicator locations (areas potentially affected by plant operations) and control locations (areas not affected by plant discharge). A possible plant effect would be indicated if the radiation level at an indicator <

location was significantly larger than at the control location. The difference would have to be greater than what ;

could be accounted for by typical fluctuations in radiation j levels arising from other sources.

I l

1

1 l

1 An additional interpretation method' involves analysis  ;

for specific radionuclides present in environmental -

samples collected around the plant site. For certain isotopes it can be. determined if the activity is the result of weapons testing or plant operations because of the different characteristic proportions in which ,

these isotopes appear in the fission product mix  ;

produced by a nuclear reactor and that produced by a l nuclear detonation.

Other means of distinguishing sources of environmental -;

radiation can be employed in interpretation of the data. . Current radiation levels can be compared with preoperational levels. Results can be related to those obtained in other parts of the country. Finally, results can be related to events known to have caused i elevated levels of radiation in the environment.  !

6.0 ~ Results and Discussion ,

Analytical results for the reporting period January to l December 1994 are presented in summary form in Appendix  !

D. For each type of analysis of each sampled medium, this table shows the annual mean and range for all indicator locations and for all control locations. ,

Results for the location with the highest annual mean are also given.

Discussion of the results has been divided into four pathways; waterborne, airborne, ingestion, and direct radiation. The individual samples and analyses within '

each category provides an adequate means of estimating radiation dose to individuals from principal pathways.

Data for individual samples are presented in tabular form in Appendix E.  !

6.1 Waterborne Pathway The water pathway of exposure from callaway Plant was  ;

evaluated by analyzing surface water, well water, bottom sediment, shoreline sediment and wetlands.

Surface Water Analysis of Tritium in surface water showed detectable activity in ten of twenty-four samples with results ranging from 172 to 3168 pCi/1. The mean Tritium concentration at the indicator location was 272 pCi/ liter and at the control location was 909 pCi/1. '

The LLDs for other samples ranged from 150 to 194 pCi/1. Tritium activity at the control location ,

appears to be due to plant discharge. A tracer study was conducted during April to determine if the plant i discharge was influencing the upstream sample. The

t results of this study showed that discharges.to the river are' carried upstream approximately two' feet past the intake structure by an eddy current created between the first downstream wing dike and the intake n structure. Since the control location sample point is located in the furthest upstream pump bay, it was influenced by the plant discharge. In May the upstream sample location was moved approximately 25 feet-upstream to the intake barge bumpers. Daily grab sampling was initiated until the composite sampler intake is moved to the new location in 1995.

No gamma emitting nuclides were detected in,any surface water samples.

Levels of activity detected in indicator surface water samples during 1994 were consistent with previously L accumulated radiological environmental data and indicate no influence from plant operations.

Ground Water In ground water samples, tritium results for all l thirteen samples were below the detection. limit which f ranged from 150 to 194 pCi/1.

No gamma emitting nuclides were detected in any ground water sample.

There was no indication of plant effects on ground water.

Bottom Sediment Analysis of bottom sediment collected in April and October showed positive Cesium-137 activity in one control sample with a concentration of 53_pCi/kg.

There were no other gamma emitting nuclides detected in bottom sediment samples. The presence of Cesium-137 in.

bottom sediment exhibits a long term residual effect of previous atmospheric nuclear tests and not an effect from plant operations.

Shoreline Sediment Shoreline Sediment samples were collected in April and October, 1993 and analyzed for gamma emitting isotopes.

Both shoreline sediment samples collected at Location A showed Cesium-137 activity of 112 pCi/kg and 101 pCi/kg. There were no gamma emitting nuclides detected in shoreline sediment samples collected at Location C. Similar levels of Cesium-137 activity due to fallout from atmospheric nuclear testing were

observed in 1984, 1985, 1987, 1988, 1989, 1990, 1991, 1992, and 1993.

Wetlands Analysis for alpha emitters showed detectable activity in all samples, with results ranging from 9904 to 13290 pCi/kg. The average sample concentration at the indicator location was 11641 pCi/kg and at the control location was 10933 pCi/kg.

The average gross beta activity in all wetlands samples ranged from 19201 to 21946 pCi/kg. The average activity at the control location was 21946 pCi/kg and at the indicator location was 19744 pCi/kg.

Potassium-40 and Cesium-137 were the only gamma emitting isotopes detected. Potassium-40 was detected in all samples with results ranging from 14573 to 21967 pCi/kg. The average concentration for indicator locations was 17223 pCi/kg and for the control location was 21967 pCi/kg.

All wetlands samples showed positive Cesium-137 activity with results ranging from 86 to 329 pCi/kg.

The average concentration for indicator locations was 178 pCi/kg and for the control location was 297 pCi/kg.

Gross alpha and gross beta activity can be attributed to naturally occurring isotopes (e.g. Potassium-40).

Cesium-137 activity present can be attributed to worldwide fallout from atmospheric nuclear testing.

6.2 Airborne Pathway Airborne pathways of exposure from Callaway Plant were evaluated by analyzing samples of air particulate and air iodine cartridges.

Airborne Particulate Grossbetaactivity[nairborneparticulaterangedfrom 0.003 to 0.058 pCi/m in 259 of the 260 samples analyzed. The average gross beta activity at the indicator and control locations were 0.023 and 0.017, respectivelyI)

[ locations was 0.061 pCi/m . The presence of l

Strontium-89 results were below the LLD for'all- '

samples. The LLDs ranged from 0.5 to 1.0 pCi/1.

1.5 to 5.3 pCi/1.-

I Isotopic Detection Limits and Activity Determination Making a reasonable estimate of the limits of detection for a counting procedure or a radiochemical method is usua'lly complicated by the presence of significant background.

It must be considered that the background is not a fixed value but a series of replicates normally distributed. The desired net activity is thus the difference between the gross sample activity and background activity distributions.

The interpretation of this difference becomes a problem if the two distributions intersect as indicated in the diagram.

BACKGROUND GROSS If a sufficient number of replicate analyses are run, it is to be expected that results would fall in a normal Gaussian f distribution. In routine analysis such replication is not carried out. Standard statistics allow an estimate of the probability of any particular deviation from the mean value. It l is common practice to report the mean one or two standard deviations as the final result.

Analytical detection limits are governed by a number of factors including:

1. Sample Size

2. Counting Efficiency The fundamental quality in the measurement of a radioactive substance is the number of disintegrations per unit time.

As with most physical measurements in analytical chemistry, it is seldom possible to make an absolute measurement of the disintegrations rate, but rather, it is necessary to compare the sample with one or more standards. The standards determine the counter efficiency which may then be used to convert sample counts per minute (cpm) to disintegrations per minute (dpm).

l C-1 l

y .

3. Background Count Rate Any counter will show a certain counting rate without a j L _ sample in position. This background counting rate comes'

[~ from several sources: 1) natural. environmental radiation U from'the surroundings,+2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background counting rate will depend on the amount of these o types of radiation and' sensitivity of.the counter to-  !

e radiation.

4. Background'and Sample Count Time

)

The amount of time devoted to counting' background depends on -

g the level of the activity being measured. In general, with-  !

L low level samples, this time should be about equal to that devoted to counting a sample.

.l

5. Time Interval Between Sample Collection and Counting j l l l Decay measurements are useful in identifying certain short- j

( lived isotopes. This disintegration constant is one of the i

basic characteristics of a specific radionuclide and is i readily determined, if the half-life is sufficiently short.

6.

Chemical Recovery of the Analytical Procedure Most radiochemical analyses are carried out in such a way that losses occur during the separations. These losses ] .

occur due to a large number of contaminants that may be t present and interfere during chemical separations. Thus it is necessary to include a technique for estimating these ,

losses in the development of the analytical procedure.. i The following method was used to determine lower limit of detection (LLD) as per NRC Regulatory Guide 4.1, Rev. 1, " Program for Monitoring Radioactivity in the Environs of Nuclear Power .

Plants", and the NRC Branch Technical Position, November 1979, "An acceptable radiological Environmental Monitoring Program". l The LLD is defined, for purposes of this guide, as the smallest concentration of radioactivity material in-a sample that will yield a net count (above system background) that will be detected  ;

with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

1' l-C-2 4

'For a particular measurement system (which may include radiochemical separation):

LLD= 4.66*sh E*V* 2.22

• Y exp (-AAt)

Where:

LLD = " A priori lower limit of detection as defined above (pCi per unit mass or volume).

sb = Standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (counts per minute).

E = Counting efficiency (counts per disintegration).

V = Sample size (units of mass or volume). ,

2.22 = Number of disintegrations per minute per picocurie.

Y = Fractional radiochemical yield (when applicable).

A = Radioactive decay constant for the particular radioisotope. ,

At = Elapsed time between sample collection (or end of the sample collection period) and time of counting.

The value of sb used in the calculation of the LLD for a f particular measurement system is based on the actual observed t variance of the background count rate, or, the counting rate of the blank sample, (as appropriate), rather than an unverified theoretically predicated variance.

In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background includes the typical contributions of other nuclides normally present in the samples.

If all but one of the values are less than the lower limit of detection, the single value x and associated two sigma error is reported.

In rounding off, the following rules are followed:

1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are unchanged. As an example, 11.443 is rounded off to 11.44.

2. If the figure following those to be retained is greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

3. If the figure following those to be retained is 5, and )

(

if there are not figures other than zeros beyond the 4 five, the figure 5 is dropped, and the last place l figure retained is increased by one if it is an odd '

number or unchanged if an even number. As an example, 11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.

- Defin'tionrof i terms'used in:the data tables are as'follows:-

.WetLWeight' A reporting unit'used with' organic tissue _ samples such as vegetation and animal-' samples in which the amount of sample'is taken to be the. weight.as received from the field.with no moisture removed. -

Dry Weight A reporting ~ unit used-for soil and-sediment in which the amount of. sample is taken to be the weight of.the sample-after removal of moisture by drying-in an oven.

3 pci/m A reporting unit used with air particulate and radiciodine data which refers-to the radioactivity content expressed in picocuries per cubic meter of air passed-through the filter and/or-the charcoal trap. Note the volume is not corrected to standard conditions.

Gamma Emitters Samples were analyzed by.high resolution or (GeLi) gamma spectrometry. The Gamma Isotopic resulting spectrum is analyzed by a computer program which scans from about 50 to 2000 kev and lists the energy peaks of any nuclides present in concentrations exceeding the sensit.vity limits set for.that particular sample.

Error Terms Figures following!" " are error terms n based on counting uncertainties at the I

95 percent confidence level. Values preceded by the "<" symbol were below the stated concentration at the 99 percent confidence' level.

Sensitivity In general, all analyses meet the sensitivity requirements of the program as given in Table III. For the few samples that do not (because of inadequate sample quantities, analytical interference, etc.) the sensitivity actually obtained in the analysis is given.

i During 1994 there was no nonradiological environmental '

monitoring-conducted in the vicinity of the Callaway '

Plant. This is consistent with Section 4.2 of1the EPP.

• Section 4.2 requires aerial photographic monitoring-during the first July 15 - September 15 period after the plant was in operation for one year and the program repeated once the following year and alternate. years  ;

for three additional periods. The aerial photographic--

monitoring was conducted during 1986 and 1987 which satisfied the first two requirements and was conducted i during 1989 and-1991,.and 1993 to satisfy the last requirement. Since all the nonradiological i environmental monitoring requirements lin Section 4.2 of j the EPP-have been satisfied and no additional t monitoring is planned at this time, this section will be deleted from future Annual Environmental Operating

1.0 INTRODUCTION

In accordance with Appendix B, Section 5.4.1 of the Callaway Plant Operating License, the following report was prepared by Union Electric on all changes in plant design, operation, tests or experiments which could have involved a .

-potentially significant unreviewed environmental question in accordance with Section 3.1 of Appendix B. '

The report covers all plant modifications / changes completed January 1,1994, through December 31,1994.

During 1994 there were eleven plant modifications / changes that could have involved a potentially significant unreviewed environmental question. The interpretations and conclusions regarding these plant modification / changes along -

with a description of the changes are presented below.

^

2.0 ENVIRONMENTAL EVALUATIONS 2.1 Callaway Modification Package 90-3023 2.1.1 Descriotion of Change This change involved the installation of a bypass line from the plant intake line at the water treatment plant, prior to any chemical addition, to the plant discharge line. This modification allows the discharge of excess river water from the intake before the water is processed and treated.

2.1.2 Evaluation of Change All construction activities were confined to areas already disturbed during plant construction and there are no cultural resources located in this area.

The water being discharged by the bypass line is untreated river water that 1 is not required for plant operations. The installation and use of this bypass line has been reviewed and approved by the Missouri Department of Natural Resources. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License. ,

' 2.2 Iallaway Modification Package 91-1041 2.2.1 Descriotion of Channe This change involved the following construction components of the Outage Maintenance Facility (OMF):

'1. ' connection of the OMF fire alarm system to the plant Ere alarm system, a 2 1 minor change to the site grading and drainage for the area were the

. OMF is located to allow for pedestrian and vehicular access to the

OMF.

2.2.2 Evaluation of Channe

~All construction activities were confined to areas already disturbed d ring plant construction. There were no cultural resources located in this area.~

The modification to the site grading and drainage resulted in minor changes to stormwater runofE However, the probable maximum precipitation evaluation was unchanged since the drainage area boundaries remain the -

same and runoffis directed toward the same overflow points for the drainage areas.

J Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating i License. (

2.3 Callaway Modification Packane 91-3041 Descriotion of Channe i i

2.3.1 This modification involved construction of an Outage Maintenance F.acility l (OMF). The OMF is a pre-engineered metal building approximately j 20,000 square feet in size located plant west of the turbine building. The j building is used by contract personnel during outages for shop and office i space and by the maintenance department during non-outage periods. j 2.3.2 Evaluation of Channe  :

1 The construction of the OMF and all site system tie-ins are in areas I previously disturbed during plant construction. There were no cultural  !

resources located in the area of this construction.

m The OMF has an oily waste water sump to collect effluent from the building floor drains. The oily waste sump is pumped to the existing oily waste water treatment plant. The small amount of additior.al' oily waste i water from the OMF was evaluated and found to have no affect on the -

,.: operation of the oily waste water treatment system. The increased loading on the sewage treatment plant was also reviewed and no adverse effects E' were found.

Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License 2.4 Callaway Modification Packane 93-2010 2.4.1 Descriotion of Change This modification provides a reliable on-site power source for all existing loads served by the temporary construction power loop. . This change j involved installation of cables and equipment necessary to tie the loop to J

the On-Site Electrical Power Distribution System, and replace the existing

]

direct buried cable with new primary cable in concrete encased duct.

2.4.2. Evaluation of Channe k This change includes installation of eight distribution transformers located throughout the plant site. Seven of the transformers contain 374 gallons of non-PCB oil each and the eighth transformer contains 480 gallons of non-PCB oil. Each transformer is located on a reinforced concrete pad with no containment capability. Each of the transformers are identified in plant procedures and administratively controlled by the plant's oil spill prevention control and countermeasure plan. Therefore, any oil spilled from these transformers would be contained in the immediate area or in the l- stonnwater drainage system.

L I Installation of this modification did not result in a significant increase in any adverse environmental impact, since all measurable non radiological '" l y environmental effects were confined to the area previously disturbed during site preparation and plant construction. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.5.1 Dex.iytion of Change' This modification involved installation of new fuel oil supply and return p lines from the auxiliary boiler booster pump to the auxiliary boiler located J on the plant south east side of the Turbine Building.- The old fuel oil supply L and return lines'will be flushed with water, capped and abandoned in place.

p 2.5.2 Evaluation ofChangt

- Installation of this modification is on land previously disturbed during plant construction and does not contain any cultural resources. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.6 : Reauest for Resolution 15024A 2.6.1 Description of Change This change involved drilling a series of test holes within the owner controlled area and either backfilling the holes with concrete or clay, or installing perforated pipe for future remediation work. Drilling these test holes was necessary due to a failure of the auxiliary boiler diesel fuel transfer line which leaked diesel fuel into the ground around the power block. These test holes are used to determine the extent of the spill.

2.6.2 Evaluation ofChange i

The test holes are drilled, used, filled or plugged in accordance with the methodology contained in the Missouri well consti.xtion rules. The test holes do not exceed a maximum depth of 20 feet below the surface. This provides at least a 10 foot buffer zone above the Graydon Chert. This

- buffer zone insures that surface runoff, perched groundwater, or diesel fuel does not percolate through to groundwater.

Drilling test holes did n ' result in a significant increase in any adverse emironmental impacts, :mce all measurable non radiological environmental effects were confined to areas previously. disturbed during site

\

s J

i preparation and plant construction. The location of the test holes did tot impact any cultural resources in the area. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.7 Reauest for Resolution 15245 2.7.1 Description of Change L This change involved installation and use of a transfer pipeline, buried underground between the diesel fuel oil recovery well and the Sre pump house sump to protect the transfer pipeline from freezing during the winter and allow the oil recovery process to continue throughout the year.

2.7.2 Evaluation of Change Installation of this pipeline did not result in a significant increase in any adverse environmental impact, since all measurable non-radiological environmental effects were confmed to the area previously disturbed during plant construction and does not contain any cultural resources. In addition, the pipeline was buried so that the original land contours are maintained and stormwater mnoff will not be impacted. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.8 Reauest for Resolution 15583 A and Plant Procedure CTP-DA-06001.

Rev._0 2.8.1 Descriotion ofChance ]

This change allows a new biopentrant, BULAB 6016, to be added to the water treatment program for the circulating and service water system. The new biopentrant will be used as a biocide treatment for the main condenser.

I 2.8.2 Evaluation of Chance j l

With the cooling tower blowdown isolated,175 gallons ofBULAB 6016 l were added to the circulating and service water system. This correlates to a maximum system concentration of 15 ppm. After one hour, sodium l hypochlorite and sodium bromide were added to the circulating and service water system to aid in killing the biological material. Since BULAB 6016 j undergoes rapid degradation in the presence of chlorine and readily decomposes by oxidation, hydrolysis, and biodegradation, this chemical does not persist in the environment and the concentration should be less

'than 0.045 in the cooling tower blowdown.

5

i The Missouri Department ofNatural Resources was notified of our intent to implement the new water treatment program and had no objections.

Therefore, this change does not constitute an unreviewed environmental .

question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.9 Pjant P,ocedure CTP-EF-06100. Rev. O and CTP-EF-06101. Rev. 0 2.91 Descriotion of Cigngs -

Procedures CTP-EF-06100 and CTP-EF-06101 were prepared to allow for chemical treatment of various portions of the Essential Service Water (ESW) system to reduce the possibility of microbiological induced -  !

corrosion (MIC). CTP-EF-06100 addresses chemical treatment for  ;

deadleg piping at the suction of the auxiliary feedwater pumps and CTP-EF-06101 address chemical treatment of the ESW supply and return piping.

2.9.2 Evaluation of Chance Two Buckman products are added to the system, BULAB 6011, a nonoxidizing biocide and BULAB 8031, a dispersant. Treatment of the '

ESW system piping to 190 ppm BULAB 6011 and 30 ppm BULAB 8031 are done to control MIC. Deadleg piping at the suction of the auxiliary feedwater pumps are treated to 250 ppm BULAB 6011 and 30 ppm BULAB 8031. Normally the ESW system is considered a closed system.

However, should the ultimate heat sink level require adjustment, water from the ultimate heat sink could be transferred to the cooling tower basin and discharged from the plant. While it is possible that residual amounts of the chemicals could be discharged, the concentration in the discharge of either chemical would be less than 0.1 ppm. The Missouri Department of Natural Resources was notified of our intent to use these chemicals to control MIC and had no objections. Therefore, this change does not ,

constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operatmg License.

-2.10 Plant Procedure CTP-EF-06100. Rev. 2 and CTP-EF-06101. Rev. 2

-+. 2.10J Descriotion of Change The procedures were revised to reflect a change in the nonoxidizing .

biocide added to the Essential Service Water System (ESW) to control microbiological induced corrosion. This change was made because the original nonoxidizing biocide was extremely flammable as well as hazardous.

2.10.2 Evaluation of Change Buckman product BULAB 6067 is added to the ESW system piping and auxiliary feedwater deadleg piping as a nonoxidizing biocide.

Normally the ESW system operates as a closed system with all water returning to the Ultimate Heat Sink (UHS). It is possible that small r quantities of the chemical could be discharged to receiving waters. The discharge concentration is estunated to be less than 0.1 ppm as a result of this treatment.

, The Missouri Department ofNatural Resources was noti 6ed of our intent to implement the new water treatment program and had no objections.

f l Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

2.11 Plant Procedure RTO-HB-01020. Rev.10 2.11.1 Descriotion of Change Revision 10 to RTO-HB-01020 allowed an increase in the amount of-hydrazine which could be discharged from the discharge monitoring tanks to the environment.

l 2.11.2 Evaluation ofChange Hydrazine is used in secondary plant systems as an oxygen scavenger and enters the discharge monitor tanks from plant floor drains or from the high and low TDS tanks. The Missouri Department ofNatural Resources was previously informed of the use of hydrazine at the plant and of the potential for discharge to the environment in the 1990 NPDES Permit Reapplication.

During normal plant operation, hydrazine may be discharged from the plant intermittently, not to exceed an average of 5 pounds per day without notification or approval from the Missouri Department of Natural L Resources. The amount of hydrazine discharged is administratively controlled to 5 pounds per day or 6 ppm assuming one tank is discharged i per day. This change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License l
