] The Callaway Plant received an Operating License on June 11, 1984. This report presents the analytical data from the environmental monitoring programs with appropriate interpretation for 1986 and the environmental evaluations for plant modifications completed during 1986.

The first section of this report summarizes and interprets the results of the radiological environmental monitoring program conducted in accordance with Technical Specification Section 3/4.12 Section 2 describes the nonradiological environmental program and its results conducted in accordance with Section 2.2 of Appendix B to the Callaway Plant Operating License. The third section of this report describes changes in plant design or operation, test, and experiments made in accordance with Section 3.1 of Appendix B to the Callaway Plant Operating License.

This Annual Environmental Operating Report is submitted in accordance with Section 6.9.1.6 of the Technical Specification and Appendix B to the Callaway Plant Operating License.

CONCLUSION

/ 'N The first section of this report contains all the

('s ') radiological environmental monitoring conducted in the vicinity of the Callaway Plant during 1986. The comparison of the results of the radiological environmental monitoring conducted during 1986 to the preoperational data showed no unexpected or adverse effects from the operation of the Callaway Plant on the environment.

The non-radiological monitoring conducted in the vicinity of the Callaway Plant during 1986 is contained in Section 2 of this report. The monitoring conducted during 1986 showed no evidence of effects of drift from the cooling tower. The foliar disease found in the vegetation during 1986 could be directly attributed to natural causes.

There were no plant modifications completed during 1986 with an unreviewed environmental question as shown in Section 3 of this report.

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 1986 for Union Electric Company, Callaway Plant, Unit 1.

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

The objectives of the radiological environmental monitoring program are as follows:

1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the operation of the Callaway Plant.

O A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vic:nity of the Callaway Plant will be compared with the pre-operational measurements at each of the sampling locations. In addition, results of the monitoring program will help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.

The Callaway Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1934 O

2-

I Q 2.0 Description of the Monitorina Program Union Electric Company has contracted with Controls for Environmental Pollution, Inc. starting May,1983, to determine the radiation levels existing in and around the Callaway Plant area. Prior to this time, all analyses were performed by Radiation Management Company.

UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected weret milk, surface water, groundwater, shoreline sediment, bottom sediment, bedload sediment, washload sediment, soll, fish, vegetation, airborne particulates, airborne radioiodine and direct radiation (TLD).

Information regarding sample preparation and analytical methods, instrumentation, detection limits, etc. used by CEP may be found in the First Quarterly Report for 1986.

s 3.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period. Samples with radionuclide activities less than detectable levels are included in the mean calculation by using one half the detection limit for the value.

A variety of radionuclides, both naturally occuring and man-made, were detected in the environment around the Callaway Plant. The man-made radionuclides found were the fission products typically found in nuclear test fallout or the result of the Chernobyl accident in the Soviet Union on April 26, 1936. The levels and fluctuations of radioactivity detected in the samples collected around the Callaway Plant were consistent with previously accumulated environmental data. All elevated levels of activity during the second quarter can be attributed to the Chernobyl accident.

i For this reporting period there was no reportable levels of radioactivity as a result of plant effluents, or analysis in which the detection limit was not achievable.

3.1 Altborne Particulates and Radiolodine Airborne particulate samples were collected from fourteen monitoring stations through January 31. 1936.

At that time, locations A2, A3, A5, A6, 81, B5, 86, B7, and B3 were deleted from the Radiological Env. onmental Monitoring Program (REMP). These monitoring locations were not required by the Callaway Plant technical speci!! cations. All of the air particulate samples were analyzed for Gross Beta activity. Gamma Spectrometry, Strontium-39 and Strontium-90 analyses were performed on quarterly composites from each station. The airborne particulate stations were also sites for airborne radioiodine.

The range and 1936 annual mean Cross Beta activity (exclusive of increased activity due to Chernobyl) at each of the sampling locations follows.

• Collected 01/02/86 - 01/30/86 Gross Beta levels at all monitoring stations during 1936 are consistent with the control stations and do not indicate any anomolous data. (The second quarter had Gross Beta levels much higher than normal due to the Chernobyl accident, but those values were not used to calculate means). Graphic presentations of the Weekly Cross Beta activities for each collection location are presented in 4

["'; Figures 1 through 5.

\'# ) Invalid samples are those with anomolous Gross Beta activity due to air sampler malfunction (i.e. hour meter malfunction, sampler malfunction, etc.) or other circumstances which may have compromised the sample integrity.

Figure 6 presents the Mean Weekly Cross Beta activity for all collection locations.

The lowest Mean Weekly Gross Beta activity (0.0ll 0.005 pC1/m3) was observed from 09/25/86 - 10/02/86 while the week exhibiting the highest activity occurred 05/15/86 - 05/22/86 (0.13430.067 pCl/m3).

Mean Quarterly Gross Beta activities were as fo!!ows:

pCl/m3 January - March 1936 0.023 3 0010 n April - June 1986 0.022 3 0012 July - September 1936 0.022 3 0003 October - December 1936 0.025 3 0010 Strontium-90 and Strontium-89 were detected in one of the quarterly composite samples during 1936. The first quarter composite for Site A-! Indicated Strontium-89 sctivity of 0.006 0.001 pCi/m3 and Strontium-90 activity of 0.007 0.003 pCl/m3 Gamma-emitting nuclides of interest detected in quarterly air particulate composites include Cesium-134, Coslum-137, Ruthenium-103, and Beryllium-7.

(See individual quarterly reports).

Airborne radiolodine was detected in several samples during 1936, most notably during the second quarter due to the radioactive plume released by the Chernobyl accident.

Airborne radiciodine activity ranged from 0.005:0.003 pC1/m3 to 0.09210.006 pC1/m3 O

3.2 Thatmahednescent Decimetry Thermoluminescent Dosimetry (TLD) was employed to determine direct radiation levels in and around the Callaway $lte. Calcium Sulfate: Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders containing copper backing to shleid out low energy radiation. The TLD's were placed at 32 locations and exchanged monthly.

Listed below are the mean monthly readings in ur/hr for all TLD's placed around the Callaway Site. These values are graphically presented in Figure 19.

• Invalid Data Figures 7 through 13 present the ur/hr values obtained for each TLD station i collected during each month of 1936.

t All of the March TLD's and the transit control TLD had abnormally high exposure levels. We have concluded that this excess exposure resulted from the exposure

[

of the packaged TLD's at some point during shipping to extremely high x rays.

Evidence to support this conclusion includes the fact that all TLDs are enclosed i in a lead film bag used to protect film from normal shipping x-rays. Also,

{

exposure levels for areas 1, 2, and 4 were higher than area 3. This would

.t).

1

indicate exposure of the TLDs to x. rays. Lastly, the transit TLD received the same (and more in some cases) exposure even though it was kept in the lead pig at all times. Also, the yearly TLDs Indicated normal exposure levels.

TLD's for the month of May showed slight increases in level of activity detected.

This can be attributed to the radioactive plume caused by the Chernobyl accident.

Annual TLD's were placed in the field on December 23,1935 and were collected on December 31, 1936. Data appearing in Table I is the result of reading and averaging the four quadrants of each TLD chip. Transit control dosirneters were used to determine the dosage received during shipment and were substracted from the gross readings obtained for each monitoring site.

3.4 Surface Water Surface Water samples were collected from three locations on a monthly basis.

Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90 and for Gamma-emitting nuclides. A summary of the Mean Gross Alpha and Gross Beta activities for Surface Water samples may be found in Table III.

Samples obtained from collection location SOI (4.8 mi SE, 84 feet upstream of discharge, North Bank) yielded a 1986 annual mean Gross Alpha activity of 2.81 1.9 pCi/l with a range from less than 2.0 pCi/l to 7.3 2.4 3 (collected 02/10/86). The mean annual Gross Beta activity for 501 was calculated to be 9.91 4.2 pCi/l with a range of Gross Beta activity from less than 3.0 pCi/l to 15.71 0.9 pCi/l (collected 04/14/86). The monthly Gross Alpha and Cross Beta results are shown in Figure 23. No Strontium-89, Strontium-90 or Tritium activity was observed above detection limit in any of the Surface Water samples collected from location 501 during 1986.

Collection location 502 (5.2 mi SE,1.1 River miles downstream of discharge, North Bank) had a range of Gross Alpha activity from less than 2.0 pCi/l to 4.211.7 pCi/l (collected 11/12/86). The 1986 mean Gross Alpha activity from this location was 1.731.1 pCi/1. An annual mean Cross Beta activity of 7.5 34.5 pCi/l was observed while the range of Gross Beta activity for this site was from less than 3.0 pCi/l to 18.911.1 pCi/l (collected 09/09/86). Figure 24 shows the monthly Gross Alpha and Gross Beta results graphically. All Surface Water samples collected from location SO2 during 1986 were less than the detection limits for Tritium, Strontium-90 and Strontium-89 (500 pCi/1,1.0 pCi/I and 1.5 pCi/1, respectively).

's Figure 25 presents the monthly Gross Alpha and Gross Beta results for samples collected during 1986 from collection location 503 (68 mi E, City of St. Louis Water Intake). A range of Gross Alpha activity from less than 2.0 pCi/l to 4.811.7 pCi/1 (collected 09/09/86) was observed in the samples collected from location 503. The 1986 mean Gross Alpha activity for samples from this location was calculated to be 1.411.1 pCI/1. Results of Gross Beta analyses for Surface Water samples from Location 503 ranged from less than 3.0 pCi/l to 13.11 0.8 pCl/l collected 09/09/86. A 1986 annual Gross Beta activity of 7.314.1 pCi/l was observed for this site. No Strontium-90, Strontium-89 or Tritium were detected in any of the Surface Water samples collected from this location diring 1986.

The 1986 mean annual Gross Alpha and Gross Beta activities for all Surface Water samples were 2.01 1.5 pCi/l and 8.314.4 pCi/1. No gamma-emitting nuclides of interest were detected in the 1986 Surface Water samples.

During 1986, the upstream Surface Water samples and the downstream Surface Water from October to December were daily grab samples composited over the month.

This was due to continuous maintenance problems with the upstream sampler and flooding of the downstream sampler by the Missouri River in October.

To reduce the out-of-service time for the upstream sampler, a redesign of the sampler will be completed in 1987.

3.3 Sediment Washload, Bedload and Bottom sediment samples were collected quarterly from three locations along the Missouri River. Samples were analyzed for Gross Alpha, Gross Beta, Strontium-39, Strontium-90 and by Gamma Spectrometry. A summary of mean Gross Alpha and Gross Beta activities for all sediment samples collected during 1986 is presented in Table IV.

Washload sediment samples collected from Location A (4.9 mi SSE,0.6 river mile upstream of discharge, North Bank) had a range of Gross Alpha activity from 2.710.7 pCl/g to 6.3 11.5 pCi/g collected 05/23/36. The mean annual Gross Alpha activity for 1986 was 4.31.51 pCi/g for Washload sediment samples collected from Location A. The 1936 mean Gross Beta activity for Wash!oad sediments collected at Location A was calculated to be 3.712.2 pCi/g. A chronological presentation of all Gross Alpha and Gross Beta results for Washload sediment samples from this site may be found in Figure 26. Strontium-90 was detected in no Washload sediment samples collected during 1936. No Strontium-89 was detected in any of the Location A Washload samples. No gamma-emitting r.uclides of interest were detected in any of the Washload sediment samples co!!ected from Location A during 1936.

Figure 27 presents the quarterly Gross Alpha and Gross Beta results for Washload sediment collected from Location C (5.1 mi SE,1.0 river mile downstream of discharge, North Bank). Gross Alpha activity for Washload sediment samples from Collection Location C ranged from 2.03 0.5 pCi/g to 5.51.4 pCi/g 3

(collected 11/19/36). Gross Beta activity in the samples from this site ranged from 4.630.2 pCl/g to 10.3 1 0.3 pCl/g (collected 03/05/36). The 1936 mean Gross Alpha and Cross Beta levels for Washload sediments collected at Location C o

l i v were 4.0+1.3 pCi/g and 8.6+2.4 pCi/g, respectively. Strontium-90 was detected in no Washload sediment samples collected from Location C during 1986. No Strontium-89 was detected in the Washload samples collected from this location.

1.0 INTRODUCTION

O In accordance with Technical Specification 3.12.2, the annual Land Use Census within a 5 mile radius of the Callaway Plant was performed during July, 1986 by Union Electric Real Estate Department. Observations were made in each of the 16 meteorological sectors of the nearest milking animals (cows and goats), 2 nearest residence, and the nearest garden of greater than 50m (500 f 2t ) producing broad leaf vegetation. This census was completed by driving the roads within a 5 mile radius of the Callaway Plant noting the location of the above-mentioned items.

The results of the Land Use Census are presented in Table 1 thru 3 and discussed below. In the tables' the radial direction and mileage from the Callaway Plant containment are presented for each location. The radial direction is one of the 16 dif ferent compass points. The mileage was estimated from map position for each location.

2.0 CENSUS RESULTS 2.1 Milking Animals x

Table 1 presents the locations where milking animals were observed within the 5 mile radius of the Callaway Plant.

) There were three new milking animals observed during the 198 6 census. One cow was located in the SSW radial direction and an additional two cows were observed at the SW radial direction. None of the census observations resulted

, in changes to the current milk sampling locations.

2.2 Nearest Resident Table 2 presents the location of the nearest resident to the Callaway Plant in each of the 16 meteorological sectors.

There were no changes in the nearest resident noted in the 198 6 census.

2.3 Vegetable Gardens The, location of the nearest vegetable garden of greater than 50m producing broad leaf vegetation is presented in Table

3. Several changes were noted in the garden locations during the 198 6 census. However, none of the changes noted resulted in changes to the current vegetable sampling locations.

Abstract Controls for Environmental Pollution, Inc (CEP) has conducted a radiological monitoring program for Union Electric Company (UEC), Callaway Plant, Unit 1,' since May 5,1983.

This quarterly report presents data for the months of January, February, and March,1986.

Evaluation of radiation levels in the environs around Union Electric Company's Callaway

[ Plant entailed sampling at strategic points in various exposure pathways. The following types of samples were co!!ected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment,' washload sediment, shoreline sediment, fish, airborne j particulates, airborne radiciodine, direct radiation (TLD) and soil.

Analytical results are presented and discussed along with other pertinent information.

Possible trends and anomalous results, as interpreted by Controls for Environmental Pollution, Inc., are discussed.

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the first quarter of 1986 for Union Electric Company, Callaway Plant.

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

The objectives of the radiological environmental monitoring program are as follows:

1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiological impact on the environment caused by the operation of the Callaway Plant.

O A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations. In addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.

The Ca!!away Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1984.

O m

2.0 Description of the Monitoring Program Union Electric Company has contracted with Controls for Environmental Pollution, Inc. starting Atay 1983, to determine the radiation levels existing in and around the Callaway Plant area.

3 UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples co!!ected this quarter were: milk, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radiolodine and direct radiation (TLD).

Locations of the monitoring sites are shown in Figures I and 2. Tab;e 1 presents the monitoring sites and the respective samples collected. Sample collection frequency for each of the monitoring locations is depicted in Table II.

C)

Two changes in the monitoring program occured during the first quarter,1986. The first change involved the deletion of 9 air monitoring stations which are not required by

the Callaway Plant Technical Specifications. These locations were deleted due to the i

increasing costs to maintain the additional air monitoring stations. The other change was in the sample collection frequency for sediment samples. The samples are now i

collected on a quarterly basis as required by the Callaway Plant NPDES permit.

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

9 (d ) 3.0 Analytical Procedures The analytical procedures described below are those routinely used by CEP to analyze samples.

3.1 Airborne 3.1.1 Gross Alpha and Gross Beta The glass-fiber filter, type A/E (99 percent removal efficiency at I micron particulate), is placed into a two-inch stainless steel planchet and counted for Gross Alpha and Gross Beta radioactivity using a low background, internal gas flow, simultaneous proportional counter (Beckman Wide Beta II), or by using a low background simutaneous counter (Tennelec LB5100),

or by using a ten channel low-level planchet counting system (Berthold LB770).

3.1.2 Gamma Spectrometry i

j The filters are composited according to station and aealed in a small, plastic Marinelli beaker. The filters are then counted using either a Ge(Li) or intrinsic germanium detector which is coupled to a 4096 channel computer based, multi-channel analyzer (Northern Scientific TN4500). The resulting spectrum is then analyzed by the computer and specific nuclides, if present, identified and quantized.

3.1.3 Strontium-89 and Strontium-90 l The composited filters are dissolved in acid and brought to a known volume. Strontium carrier is added and the solution is evaporated to dryness. The resulting residue is taken up in dilute acid. Yttrium carrier is added and placed into ingrowth for 14 days. Af ter the ingrowth period has been established it is back extracted into an aqueous phase, precipitated as t

the oxalate, counted in a low background proportional counter (Beckman V Low Beta 11 or Berthold LB770), and calculated as Strontium-90 activity.

l i

m The aqueous phase Wevaporated to a low volume, precipitated with fuming nitric acid, redissolved in water, made basic with dilute ammonium hydroxide and precipitated as the oxalate. The dried precipitate is counted in a low background proportional counter (Beckman Low Beta II or Ber: hold LB770) and the Strontium-89 activity is determined by subtracting the previously measured Strontium-90 activity and its corresponding Yttrium-90 ingrowth from the measured gross Strontium activity.

3.1.4 Iodine-131 ,

3.1.4.1 Alkaline Leach Method The radiciodine is stripped off activated charcoal by reduction using concentrated ammonium hydroxide (NH4 0H) and hydrogen peroxide (H22 0 ). The charcoal is then filtered and the remaining solution is acidilled with nitric acid (HNO3) and extracted with carbon tetrachloride (CCir;) to remove the Iodine. It is then back extracted using 0.2% hydrazirie solution, which supplies further purification and an aqueous media for precipitation. It is then precipitated with silver nitrate (AgNO3 ) and filtered on a tared glass-fiber filter as silver iodide (Agl). The dried precipitate is weighed for recovery and counted for Iodine-131 in a thin window gas flow proportional counter (Beckman Low Beta II or Berthold LB770) having a forty-one percent efficiency for Iodine-131 precipitated as silver iodide (Agl).

3.1.4.2 Camma Spectrometry Method The charcoal canister is placed directly on an intrinsic germanium detector and Iodine-131 activity determined using Method 3.1.2.

3.1.5 Direct Radiation Direct radiation measurements were taken using Thermoluminescent

(: }" Dosimeters (TL D's).' Each dosimeter consists of a Teflon wafer s_ .-

im regnated with twenty-five percent CaSO 4, :Dy phosphor. Dosimeters are annealed in an oven prior to use and are inserted into black polyethylene pouches. The CaSO4 :Dy phosphor pouches are placed in rectangular holders which contain copper shielding to filter out low energy radiation.

After exposure in the environment, the dosimeters are read in a Teledyne Isotopes model 8300 TLD reader.

using Method 3.1.2.

3.3 Milk 3.3.1 Iodine-131 j Two liters of milk containing standardized Iodine carrier are stirred with Amberlite IRA-400 anion exchange resin for one hour. The Iodine is t

l stripped from the resin with sodium perchlorate (NaCIO4 ) acidified with l nitric acid, precipitated with silver nitrate (AgNO3) and filtered on a tared

g. lass-fiber filter. The dried precipitate is weighed for percent recovery

\ - and counted for Iodine-131 in a thin window, gas flow, proportional counter (Beckman Low Beta II or Berthold BL770).

3.3.2 Strontium-89 and Strontium-90 Two liters of milk containing Strontium carrier is stirred with Dowex 50WX8 cation exchange resin at a pH of 6 for thirty minutes. All nuclides are stripped from the resin with strong acid. Method 3.1.3 is then followed beginning at the ingrowth period.

3.3.3 Gamma Spectrometry A one liter aliquot of milk is placed in a plastic Marinelli beaker and specific nuclides identified and quantized using Method 3.1.2.

7.0 Quality Control Program CEP employs a multi-faceted Quality Control Program designed to maintain high performance of its laboratory. The overall objectives of the program are to:

1.) Verify that work procedures are adequate to meet specifications of UEC.

2.) Coordinate an in-house quality control program independent of external programs, to assure that CEP is operating at maximum efficiency.

Objectives are met by a variety of procedures that oversee areas of sample receipt and handling, analysis and data review. These procedures include standard operating procedures, known and unknown spike analysis, blank analysis, reagent, carrier and nuclide standardization as well as participation in the U.S. Environmental Protection Agency's Interlaboratory Cross-check Program (See Appendix A for EPA Cross-check Results).

CEP's Quality Assurance Program is reviewed and revised (when necessary) on a regularly scheduled basis. This review assures that the program meets all current regulatory guidelines as well as maintaining the highest standards of quality assurance practices.

3.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period.

Analysis and review of data incorporates various techniques from historical comparison to statisical evaluation. Results which do not compare with the historical range are recalculated for verification. If the recalculation verifies the original result, the sample is reanalyzed if possible (i.e. sufficient sample volume or isotope half life). Once it is determined that the results obtained are accurate, a statisical

(v analysis is made. Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous.

8.1 Airborne Particulates and Radiciodine Airborne particulate samples were collected from fourteen monitoring stations during the first four weeks of 1986. After the samples collected on 01/30/86

nine monitoring stations were dropped from the Radiological Environmental i

Monitoring Program (REMP). (A2, A3, AS, A6, B1, B5, B6, B7, B8).

All of the air particulate samples were analyzed for Gross Beta activity.

Gamma Spectrometry, Strontium-90 and Strontium-89 analyses were performed i

l on quarterly composites from each station.

/^N 3.2 Thermoluminescent Dosimetry

( )

\

"' /

Thermoluminscent Dosimetry (TLD) was employed to determine direct radiation levels in and around the Callaway Site. Calcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas I and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shielding. The TLD's were placed at 52 locations and exchanged monthly.

Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to determine dosage received during shipment and were subtracted from the gross readings obtained for each monitoring site.

Exposure levels for all monitoring locations during January and February are (n)

%J consistent with background levels detected during the preoperational monitoring program.

All of the March TLDs and the transit control TLD had abnormally high exposure levels. We have concluded that this excess exposure resulted from the exposure of the TLDs at some point during shipping to extremely high x-rays. Evidence to support this conclusion includes the fact that all TLDs are enclosed in a lead film bag used to protect film from normal shipping x-rays. Also exposure levels for areas 1, 2, and 4 were higher than area 3. This would indicate exposure of the TLDs to x-rays. Lastly the transit TLD received the same (and more in some cases) exposure even though it was kept in the lead film bag at all times.

During the first quarter,' the upstream surface water samples were daily grab samples composited over the month due to the inoperability of the composite water sampler. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are summarized in Tables XIV and XV.

Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities of less than 2.0 pCi/I to 7.312.4 pCi/l and 4.710.6 pCi/l to 12.810.8 pCi/1, respectively. The positive Gross Alpha and Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40, and are consistent with the preoperational data.

All Tritium data from surface water samples were below the detection limit of 500 pCi/1.

No Strontium-89 or Strontium 90 was detected in any of the surface water samples collected this quarter.

Gamma Spectral analysis of surface water samples showed no detectable activity from isotopes of interest.

N 3.6 Fish Due to adverse weather conditions and paucity of fish, no fish samples were collected from locations A and C during January. Five species of fish were collected at location D during January and from each of the three collection locations during the remainder of the quarter. Types of fish collected during this quarter were: goldeye, white crappie, freshwater drum, shortnose gar, largemouth bass, bigmouth buf falo, carp, grass carp, river carpsucker, channel catfish, smallmouth buffalo, gizzard shad and shorthead redhorse. Gross Alpha, Cross Beta, Strontiura-90, Strontium-89 and Gamma Spectral analysis were l

l performed on all fish collected each month. Results are presented in Tables l

XXil thru XXVil. The activity levels are consistent with the preoperational data.

Gross Alpha levels for all but two of the samples were below the detection limit 5

of 0.3 pCi/g. Gross Beta activities ranged from a low of 1.5 1 0.1 pCi/g (sample CA-AQF-D, River Carpsucker, collected 01/14/36) to a high of 5.710.1 pCi/g (sample CA-AQF-A, Freshwater Drum, collected 03/04/36). Gross Alpha and Gross Beta activities seen in fish samples could be attributed to naturally occurring isotopes (e.g. Potassium 40).

Strontium-90 analyses results were below the detection limit of 0.20 pCi/g.

All fish data for Strontium-89 were below the detection limit of 0.30 pCi/g.

Results of Gamma Spectral Analysis may be found in Tables XXIll, XXV, and XXVil.

8.7 Milk Milk samples were collected monthly from two locations, the Green Farm and the Schneider Farm. The Green Farm supplied cow's milk while the Schneider Farm provided both cow's milk and goat's milk. No samples were available from the Schneider Farm in February because the cow and goat were both dry at that time. Samples were collected in January and March. Analyses for Iodine-131, Elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVIII and XXIX present results of these analyses.

Iodine-131 was not detected in any of the milk samples during this period. All milk samples collected during the first quarter were below the detection limit of 2.0 pCi/l for Strontium-89 and below the detection limit of 1.0 pCi/l for Strontium-90.

No gamma-emitting isotopes of interest were detected in any of the milk samples.

Isotopic Detection Limits and Activity Determinations

\ "/

Making a reasonable estimate of the limits nf detection for a counting procedure or a radiochemical method is usually complicated by the presence of significant background.

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

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

Background Gross m

)

U d  %

If a sufficient number of replicate analyses are run, it is to be expected that the results would fall in normal Gaussian distribution. Standard statistics allow an estimate of the probability of any particular deviation from the mean value, it is common practice to report the mean 1one or two standard deviations as the final result. In routine analysis such replication is not carried out, and it is not possible to report a Gaussian standard deviation z i

one or two Poisson standard deviations. The reported values are then considered to give l

some indication of the range in which the true value might be expected to occur.

The simplest possible case to consider would be one where the background is negligible and the sample activity is zero. It is sometimes not realized that if a series of counts is taken l G l

l

on such a system, half of the net values should be less than zero. Negative counts are not possible, of course. But when there is an appreciable background, the entire scale is raised.

The resulting situation: half of the sample counts on a zero activity sample would be less-than background. This negative net count occurs frequently in low-level measurements, causing considerable concern. Actually, such results are to be expected.

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

1. Sample Size Counting Ef ficiency 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 disintegration 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).

3. Background Count Rate Any counter will show a certain counting rate without a sample in position.

This background counting rate comes from several sources: 1) natural environmental radiation from the surroundings, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background counting rate will depend on the amounts of these types of radiation and sensitivity of the counter to the radiation.

4. 13ackground and Sample Counting Time The amount of time devoted to the counting of the background depends on the level of activity being measured. In general, with low !cvel samples, this time should be about equal to that devoted to counting a sample.

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

The disintegration constant is one of the basic characteristics of a specific radionuclide and is readily determined, if the half-life is sufficiently short.

6. Chemical Recovery of the Analytical Procedures 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 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.

The activities per unit sample mass or volume are determined using the following formula:

O lh O --

12 A= C-B ~

+ 1.96 (2.22) (V) (T) (R) (E) (e- A t) (2.22) (V) (R) (E) (e- A t)

WHERE:

A= Activity as pCi per unit sample mass or volume. >

C= Sample counts.

B= Background counts.

V= Sampic volume or mass analyzed.

E= Counter efficiency in cpm /dpm.

2.22 = Numerical constant to convert disintegrations per minute to picocuries.

(e - A t) = Decay factor to correct the activity to time of collection.

T= Counting time in minutes for sample and background.

1.96 = Statistical constant for the 95% confidence level.

R= Chemical recovery or photon yield.

{

k

CEP uses the following method to determine lower limit of detection (LLD) as per NRC Regulatory Guide 4.1, Rev.1, " Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants", and the NRC Branch Technical Position, November 1979, "An Acceptable Radiological Environmental Monitoring Program". The LLD is defined, for purposes of this guide, as the smallest concentration of radioactive 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.

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

LLD = 4.66 sb E V 2.22 Y exp ( Aat)

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

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

E = Counting ef ficiency (as counts per disintegration).

V = Sample size (in 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 particular measurement system is based on the actual observed variance of the background counti: r, rate, or, of the counting rate of the blank sample, (as appropriate), rather thr.'n on an unverified theoretically predicated variance.

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

l.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the second quarter of 1936 for Union Electric Company, Callaway Plant.

In compliance with federal and state regulations and in its concern to maintain the l

quality of the local environment UEC began its radiological monitoring program in April,1932.

The objectives of the radiological environmental monitoring program are as follows:

1) to establish baseline radiation levels in the environs prior to reactor operations; 2) i i

to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the operation of the Callaway Plant.

A number of techniques are being used to distinguish Callaway Plant effects from O

} other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations, in addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.

The Callaway Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1934 During the weekend of April 26, 1936 a Soviet Union (USSR) nuclear reactor located in

(m)

'a Chernobyl (north of Kiev) suffered a major accident, resulting in a significant release of radioactivity. Due to the easterly flow of the upper air, the radioactive plume drif ted over the Asian continent and the Pacific Ocean before arriving on the west coast of the United States. UEC first detected contamination from the plume in their air particulate samples co!!ected during the week of 05/08/86-05/15/36. Other sample types indicated increases in activity during the second quarter of 1986. These are discussed in the body of this report. All elevated levels of activity can be attributed to the Chernobyl accident and the resulting radioactive plume.

2.0 Description of the Monitoring Program Union Electric Company has contracted with Controls for Environmental Pollution, Inc. starting May 1983, to determine the radiation levels existing in and around the Callaway Plant area.

3.0 Analytical Procedures The analytical procedures routinely used by CEP to analyze samples are discussed in the First Quarter 1936 Report (pages 15 to 19). No new analytical methods were used this quarter.

4.0 Sample Pre.paration Methods Sample preparation methods used by CEP are discussed in the First Quarter 1936 Report (page 20). No new sample preparation methods were used this quarter.

5.0 Major Instrumentation Major analytical instrumentation used by CEP are discussed in the First Quarter 1936 Report (pages 21 to 23). No new instrumentation was used for sample analysis this quarter.

6.0 Isotopic Lower Limits of Detection and Activity Determinations O

A discussion of the . calculations used in determining lower limits of detection and activity by Controls for Environmental Pollution, Inc., is found in Appendix B, First Quarter 1936 Report.

Table Ill in the first quarter 1936 report gives the lower limits of detection for radiochemical and chemical analytical methods.

Table IV in the first quarter 1936 report gives the lower limits of detection for Gamma Spectrometry.

The sampic counting times and the aliquot size used for lower limit of detection calculations and actual analyses are shown in Tables V and VI, in the first quarter 1936 report, respectively.

7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter 1936 Report (page 23). No changes in the Quality Control Program occured this quarter.

8.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period.

Analysis and review of data incorporates various techniques from historical comparison to statisical evaluation. Results which do not compare with the historical range are recalculated for verification. If the recalculation verifies the original result, the sample is reanalyzed if possible (i.e. sufficient sample volume or isotope half life). Once it is determined that the results obtained are accurate, a statisical analysis is made. Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous and will be so noted in J

the report.

8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from five (5) monitoring stations on a weekly basis from April 3,1936 through July 3,1936. The five airborne particulate stations were also collection sites for airborne radiciodine (see Table I VIII).

i l

8.2 Thermoluminescent Dosimetry Thermoluminscent Dosimetry (TLD) was employed to determine direct radiation levels in and around the Callaway Site. Calcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas I and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shielding. The TLD's were placed at 52 locations and exchanged monthly.

Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to determine dosage received during shipment and were subtracted from the gross readings obtained for each monitoring site.

Exposure levels for all monitoring locations during April and June are consistent with background IcVels detected during the preoperational monitoring program.

Most of the May TLDs had higher than normal exposure !cvels. This is most likely due to exposure of the TLD's to the radioactive plume caused by the Chernobyl accident. Other environmental samples collected duruing this time (most notably air particulate and radioiodine) had elevated activities.

8.4 Surface Water Surface water samples were collected from three locations on a monthly basis.

During the second quarter, the upstream surface water samples were daily grab samples composited over the month due to the inoperability of the continuous composite water sampler. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are summarized in Tables XIV and XV.

Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities from less than 2.0 pCi/l to 4.711.5 pCi/l and 4.510.6 pCi/l to 15.710.9 pCi/l, respectively. The positive Gross Alpha and Gross Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and are consistent with the preoperational data.

O All Tritium data from surface water samples were below the detection limit of 500 pCi/l.

No Strontium-89 or Strontium 90 was detected in any of the surface water samples collected this quarter.

Gamma Spectral analysis of surface water samples showed no detectable activity from isotopes of interest.

8.6 Fish k,j}

Fish were collected monthly from three (3) locations. Types of fish collected during this quarter were: goldeye, freshwater drum, shortnose gar, white bass, paddlefish, bigmouth buffalo, carp, river carpsucker, bluesucker, channel catfish, flathead catfish, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on all fish collected each month. Results are presented in Tables XX11 thru XXVII.

The activity levels are consistent with the preoperational data.

Gross Alpha levels for all of the samples were below the detection limit of 0.3 pCi/g. Gross Beta activities ranged from a low of 2.9 10.1 pCi/g (sample CA-AQF-A, River Carpsucker, collected 04/22/86) to a high of 3.610.2 pCi/g (sample CA-AQF-D, Carp, collected 06/25/36). Gross Alpha and Gross Beta activities

( seen in fish samples can be attributed to naturally occurring isotopes (e.g.

Potassium-40).

Strontium-90 analyses results were generally below the detection limit of 0.20 pCi/g. Two fish collected in the second quarter exhibited Strontium-90 activity.

The Strontium-90 activity in the fish was not related to the operation of the Callaway Plant, since there has been no Strontium-90 detected in plant effluents. Strontium-90 activities ranged from less than 0.20 to 0.6910.20 pCi/g (CA-AQF-D, Flathead Catfish, collected 04/23/36).

All fish data for Strontium-89 were below the detection limit of 0.30 pCi/g.

8.7 Milk Milk samples were collected monthly from two locations, the Green Farm and the Schneider Farm. The Green Farm supplied cow's milk while the Schneider Farm provided both cow's milk and goat's milk. Analyses for Iodine-131, Elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVill and XXIX present results of these analyses.

Iodine-131 was detected in nine of the milk samples during this period. This occured during the collection period 05/27/86 to 06/23/86. The positive Iodine-131 results are attributed to the Chernobyl accident.

Milk samples collected on 04/26/86 and 05/27/86 at sample location M5B indicated Strontium-90 activity of 1.1 10.8 pCi/l and 2.0 0.8 1 pCi/1, respectively.

All of the other rnilk samples collected during the second quarter were below the detection limit of 2.0 pCi/l for Strontium-89 and below the detection limit of 1.0 pCi/l for Strontium-90.

No gamma-emitting isotopes of interest were detected in any of the milk samples.

, ) 8.8 Vegetation V

Vegetation samples were collected from sampling locations during the second quarter of 1986. Vegetation samples consisted of cabbage, lettuce, spinach, mustard greens, and turnip greens co!!ected from the Hazlett, Zimmer, Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha,

. Gross Beta, Iodine-131 and by Gamma Spectrometry. Results are presented in Tables XXXI and XXXII.

Gross Alpha activities in the vegetation samples collected the quarter were all l less than 0.3 pCi/g. These Gross Alpha activities are consisent with the levels found in the preoperational monitoring.

I Gross Beta levels observed in the vegetation samples ranged from 2.11 0.1 pCi/g y

) to 26.510.3 pCi/g.

One gamma-emitting isotopes of interest (Cesium-137) was detected in three of the samples. No other isotopes isotopes of interest were detected. Cesium-137 was a major component of the radioactive plume released af ter the Chernobyl accident, and the positive results from our samples are likely the result of Chernobyl.

a 1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the third quarter of 1986 for Union Electric Company, Callaway Plant.

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

The objectives of the radiological environmental monitoring program are as follows:

1) to estab!1sh baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the operation of the Callaway Plant.

A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of estab!!shed background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the samp!!ng locations. In addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.

The Callaway Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality en October 2,1984.

2.0 Description of the Monitoring Program v '

Union Electric Company has contracted with Controls for Environmental Pollution, Inc. starting May 1983, to determine the radiation levels existing in and around the Callaway Plant area.

A summary of the Callaway Plant Monitoring Program is contained in the first quarter report 1986 (page 3). No changes in the monitoring program occured during the third quarter,1986.

3.0 Analytical Pr%es The analytical procsdures routinely used by CEP to analyze samples are discussed in the First Quarter 1986 Reoort (pages 15 to 19). No new analytical methods were used this quarter.

4.0 Sample Preparation Methods '

Sample preparation methods used by CEP are discussed in the First Quarter 1986 Report (page 20). No new sample preparation methods were used this quarter.

5.0 Major Instrumentation Major analytical instrumentation used by CEP are discussed in the First Quarter 1986 Report (pages 21 to 23). No new instrumentation was used for sample analysis this quarter.

1 6.0 Isotopic Lower Limits of Detection and Activity Determinations A discussion of the calculations used in determining lower limits of detection and i activity by Controls for Environmental Pollution, Inc., is found in Appendix B, First Quarter 1986 Report.

8.0 Data Interpretations and Conclusions -

This section addresses interpretations and corclusions regarding 11 types of samples analyzed during this report period, b Analysis and review of data incorporates various techniques from historical comparison to statisical evaluation. Results which do not compare with the historical range are recalculated for verification. If the recalculation verifies the original result, the sample is reanalyzed if possible (i.e. sufficient sample volume or isotope half life). Once it is determined that t.he results obtained are accurate, a statisical analysis is made. Results which are obtliers with respect to historical comparison of previous data are considered out of barekine range or ancmclous and will be so noted in the report.

',. All of the air particulate samples were analyzed for Gross Beta activity.

s Gamma Spectrometry, Strontium-90 and Strontium-89 aulhses were performed

on quarterly composites from each station.

The range of Gross Beta activity at each of the sampling locations follows.

Measurements are in terms of pC1/m3.

Mean weekly Cross Beta activities ranged from a low of 0.01110.005 pCi/m3 during the collection period of 09/25/86-10/02/86 to a high of 0.03210.004 pCl/m3 during the collection period of 07/03/86-07/10/86.

All of the airborne particulate composite analyses for Strontium-89 and Strontium-90 were less than the lower limit of detection (0.002 pCi/m3).

No gamma emitting isotopes of interest were detected in the quarterly site composites.

Results of the airborne radiolodine analyses may be found in Table VIII. Three samples Indicated detectable levels of lodine-131, Site A7 during their collection period 07/03/86-07/10/86, and Sites Al and A7 during the collection period 07/10/86-07/17/86.

Levels and fluctuations of activity in the air particulate and radiodine samples are consistent with the previously accumulated preoperational data.

8.2 Thermoluminescent Dosimetry Thermoluminscent Dosimetry (TLD) was employed to determine direct radiation levels in and around the Callaway Site. Calcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas I and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shielding. The TLD's were placed at 52 locations and exchanged monthly.

Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to determine dosage received during shipment and were subtracted from the gross readings obtained for each monitoring site.

s Exposure levels for all monitoring locations during July, August, and September are consistent with background levels detected during the preoperational monitoring program.

8.3 Well Water Well water samples were collected monthly from three locations and analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, and gamma-emitting nuclides.

Table XII presents the results of the radiochemical analyses. Gross Alpha activity ranged from less than 2.0 pCi/l to 5.1 11.7 pCl/1. Gross Beta levels varied from less than 3.0 pCl/l to 10.8 10.8 pCi/1. The Gross Alpha and Gross Beta levels were consistent with the preoperational data.

Results for Tritium analysis were below the detection limit of 500 pCi/l for all samples.

All sample results for Strontium 89 and Strontium 90 analysis were below the detection limits of 1.5 pCi/l and 1.0 pCl/l respectively.

Gamma spectrometry showed no detectable levels of isotopes of interest.

8.4 - Surface Water Surface water samples were collected from three locations on a monthly basis.

During the third quarter. the upstream surface water samples were daily grab samples composited over the month due to the inoperability of the continuous

, composite water sampler. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are summarized in Tables XIV and XV.

Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities from less than 2.0 pCl/l to 4.811.7 pCl/l and 4.110.5 pCi/l to 18.911.1 pCi/1, respectively. The positive Gross Alpha and Gross Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and are consistent with the preoperational data. ,

All Tritium data from surface water samples were below the detection limit of 500 pCi/l.

No Strontium-89 or Strontium 90 was detected in any of the surface water samples collected this quarter.

Gamma Spectral analysis of surface water samples showed no detectable activity from isotopes of interest.

m (a) 8.6 Fish Fish were collected monthly from three (3) locations. Types of fish collected during this quarter were: goldeye, freshwater drum, shortnose gar, longnose gar, shovelnose sturgeon, paddlefish, carp, river carpsucker, blue sucker, channel catfish, blue catfish, shorthead redhorse, flathead catfish, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on all fish collected each month.

Results are presented in Tables XXII thru XXVII. The activity levels are consistent with the preoperational data.

Gross Alpha activity was detected in one sample (CA-AQF-D, Channel Catfish, collected 08/01/86). Gross Beta activities ranged from a low of 0.910.1 pCi/g (sample CA-AQF-A, Carp, collected 09/16/86) to a high of 8.6 0.2 pCl/g (sample 1

Ox CA-AQF-C, River Caprsucker, collected 08/05/86). Gross Alpha and Gross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. Potassium-40).

All fish data for Strontium-90 and Strontium-89 were below the detection limits of 0.20 pCi/g and 0.30 pCi/g, respectively.

Results of Gamma Spectral Analysis may be found in Tables XXIII, XXV, and XXVII.

8.7 Milk O Milk samples were collected monthly from two locations, the Green Farm and i

the Schneider Farm. The Green Farm supplied cow's milk while the Schneider )

Farm provided both cow's milk and goat's milk. Analyses for Iodine-131, Elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVIII and XXIX present results of these analyses.

Iodine-131 was detected in four of the milk samples during this period. This occured during the collection period 07/22/86 to 08/26/86.

All of the milk samples collected during the third quarter were below the detection limit of 2.0 pCi/l for Strontium-89 and below the detection limit of 1.0 pCi/l for Strontium-90.

No gamma-emitting isotopes of interest were detected in any of the milk samples.

l 8.8 Venetation Vegetation samples were collected from sampling locations during the third quarter of 1986. Vegetation samples consisted of cabbage, lettuce, spinach, mustard greens, and turnip greens collected from the Hazlett, Zimmer, Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha, Gross Beta, Iodine-131 and by Gamma Spectrometry. Results are presented in Tables XXX and XXXI.

Gross Alpha activity of 0.3 10.1 pCl/g was detected in one vegetation sample (CA-FPL-V7, 09/23/86). Gross Alpha activities in the other vegetation samples collected during the quarter were all less than 0.3 pCl/g. These Gross Alpha activities are consisent with the levels found in the preoperational monitoring.

i s

! Gross Beta levels observed in the vegetation samples ranged from 2.410.1 pCi/g

! to 17.410.3 pCl/g.

One gamma-emitting isotope of interest (Ceslum-137) was detected in one of the samples, (Hazlett Farm, Turnip Greens collected 08/12/36). No other Isotopes of interest were detected.

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the fourth quarter of 1936 for Union Electric Company, Callaway Plant.

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

The objectives of the radiological environmental monitoring program are as follows:

1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the operation of the Callaway Plant.

O A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations. In addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.

The Callaway Plant is located on a plateau a,g.oximately five miles north of the Missouri River in Ca!!away County, Missouri. The plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1984.

O

[ 2.0 Description of the Monitoring Program Union Electric Company has contracted with Controls for Environmental Po!!ution, Inc. starting May 1933, to determine the radiation levels existing in and around the Callaway Plant area.

A summary of the Callaway Plant Monitoring Program is contained in the first quarter report 1936 (page 3). No changes in the monitoring program occured during the fourth quarter,1986.

3.0 Analytical Procedures The analytical procedures routinely used by CEP to analyze samples are discussed in the First Quarter 1986 Report (pages 15 to 19). No new analytical methods were used this quarter.

t 4.0 Sample Preparation Methods Sample preparation methods used by CEP are discussed in the First Quarter 1936 Report (page 20). No new sample preparation methods were used this quarter.

5.0 Major Instrumentation Major analytical instrumentation used by CEP are discussed in the First Quarter 1986 Report (pages 21 to 23). No new instrumentation was used for sample analysis this quarter.

6.0 Isotopic Lower Limits of Detection and Activity Determinations A discussion of the calculations used in determining lower limits of detection and activity by Controls for Environmental Pollution, Inc., is found in Appendix B, First y Quarter 1986 Report.

Tabic ill in the first quarter 1986 report gives the lower limits of detection for radiochemical and chemical analytical methods.

Table IV in the first quarter 1986 report gives the lower limits of detection for Gamma Spectrometry.

The sample counting times and the aliquot size used for lower limit of detection calculations and actual analyses are shown in Tables V and VI, in the first quarter 1986 report, respectively.

7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter 1936 Report (page 23). No changes in the Quality Control Program occured this quarter.

O 8.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period.

Analysis and review of data incorporates various techniques from historical comparison to statisical evaluation. Results which do not compare with the historical range are recalculated for verification. If the recalculation verifies the original result, the sample is reanalyzed if possible (i.e. sufficient sample volume or isotope half life). Once it is determined that the results obtained are accurate, a statisical analysis is made. Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous and will be so noted in the report.

/ \ 8.1 Airborne Particulates and Radioiodine

\v) Airborne particulate samples were collected from five (5) monitoring stations on a weekly basis from October 2,1986 through January 2,1987. The five airborne particulate stations were also collection sites for airborne radioiodine (see Table Vill).

All of the air particulate samples were analyzed for Gross Beta activity.

Gamma Spectrometry, Strontium-90 and Strontium-89 analyses were performed on quarterly composites from each station.

i The range of Gross Beta activity at each of the sampling locations follows.

Measurements are in terms of pCi/m3 Collection Location Minimum (pCi/m3) Maximum (pCi/m3) v Site A1 0.00910.001 0.04620.002 Site A7 0.01010.001 0.03510.002 Site A8 0.01310.002 0.04130.002 Site A9 0.00630.001 0.03430.002 Site B3 0.01610.002 0.05010.002 Table VII, Gross Beta in Airborne Particulates, shows that the Gross Beta activity ranged from a minimum at Site A9 of 0.00610.001 pCi/m3, collected 12/04/36-12/11/36 to a maximum of 0.0501 0.002 pCi/m3 at Site B3 during the collection period of 10/16/86-10/23/86.

The highest mean Gross Beta activity during the report period was observed at Site B3 with a mean activity of 0.02910.010 pCi/m3. Mean Gross Beta activities

' ,O at the other sites varied from 0.020_+0.008pCi/m3 at Site A7, to 0.02S_+0.008 g

j pCi/m3 at Site AS.

t

Mean weekly Gross Beta activities ranged from a low of 0.01410.003 pCi/m3 during the collection period of 11/06/36-11/13/36 to a high of 0.03310.006 pCi/m3 during the collection period of 12/17/86-12/26/86.

All of the airborne particulate composite analyses for Strontium-89 and Strontium-90 were less than the lower limit of detection (0.002 pCi/m3 ).

No gamma emitting isotopes of interest were detected in the quarterly site composites.

Results of the airborne radiciodine analyses may be found in Table VIII. No samples exhibited levles of Iodine-131 greater than the detection limit of 0.006 pCi/m3 Levels and fluctuations of activity in the air particulate and radiodine samples O

i are consistent with the previously accumulated preoperational data.

N 8.2 Thermoluminescent Dosimetry Thermoluminscent Dosimetry (TLD) was employed to determine direct radiation i

1 levels in and around the Callaway Site. Calcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas I and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shielding. The TLD's were placed at 52 locations and exchanged monthly.

I

!' Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to l determine dosage received during shipment and were subtracted from the gross readings obtained for each monitoring site.

Exposure levels for all monitoring locations during October, November, and December are consistent with background levels detected during the i preoperational monitoring program.

3.3 Well Water Well water samples were collected monthly from three locations and analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, and gamma-emitting nuclides.

Table XII presents the results of the radiochemical analyses. Gross Alpha activity ranged from less than 2.0 pCi/l to 5.0 11.7 pCi/1. Gross Beta levels varied from less than 3.0 pCi/l to 13.3 10.8 pCi/1. The Gross Alpha and Gross Beta levels were consistent with the preoperational data.

Results for Tritium analysis were below the detection limit of 500 pCi/l for all samples.

All sample results for Strontium 89 and Strontium 90 analysis were below the detection limits of 1.5 pCi/l and 1.0 pCi/l respectively.

Gamma spectrometry showed no detectable levels of isotopes of interest.

Results are summarized in Table XIII.

m 8.4 Surface Water Surface water samples were collected from three locations on a monthly basis.

.f During the fourth quarter, the upstream and downstream composite water samplers were inoperable due to equipment failures and flooding of' sampler a

stations. Therefore, daily grab samples were taken and composited over the month. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are summarized in Tables XIV and XV.

, Gross Alpha and Gross Beta analyses of surface water samples showed a range of

activities from less than 2.0 pCi/l to 4.2 21.7 pCi/l and less than 3.0 pCi/l to 9.810.7 pCi/l, respectively. The positive Gross Alpha and Gross Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and are consistent with the preoperational data.

l All Tritium data from surface water samples were below the detection limit of 4

500 pCi/1.

(

No Strontium-89 or Strontium 90 was detected in any of the surface water i samples collected this quarter.

8.5 Sediment Washload, Bedload and Bottom Sediment samples were collected in November from three locations alond the Missouri River. Samples were analyzed for Gross Alpha, Gross Beta, Strontium-90, Strontium-89, and by Gamma Spectrometry.

Results are summarized in Tables XVI thru XXI.

The following ranges of Gross Alpha and Gross Beta activities were observed in the washload, bedload and bottom sediments.

Gross Alpha Cross Beta Range Range Sample Type pCi/g pCi/g Washload 3.71.2-5.51.4 1 1 7.90.7-9.70.7 1 1 Bedload 0.80.2-i.30.2 1 1 2.30.1-6.70.6 1 1 Bottom 2.00.2-2.30.2 3 1 2.00.1-2.40.1 1 2 The highest activity of Gross Alpha (5.5 11.4 pCi/g) was seen in the Bedload sediment at sample location C (1.0 river miles downstream of discharge north bank). The highest activity of Gross Beta (9.73 0.7 pCi/g) was seen in the Washload sediment at sample location C (1.0 river miles downstream of discharge north bank).

No Strontium-89 or Strontium-90 was detected in the washload, bedload, or bottom sediments collected during the fourth quarter 1986.

Gamma Spectral analysis of the sediment sz,mples collected during this report period are detailed in Tables XVII, XIX and XXI.

8.6 Fish Fish were collected monthly from three (3) locations. Types of fish collected during this quarter were: goldeye, freshwater drum, shortnose gar, bigmouth buffalo, blue catfish, largemouth bass, paddlefish, carp, river carpsucker, channel catfish, golden redhorse, white bass, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on all fish collected each month. Results are presented in Tables XXII thru XXVII. The activity levels are consistent with the preoperational data.

Gross Alpha activity was detected in seven samples during this quarter. Gross Beta activities ranged from a low of 1.00.1 1 pCi/g (sample CA-AQF-A, Freshwater Drum, co!!ected 11/19/36) to a high of 3.010.2 pCi/g (sample CA-AQF-C, Largemouth Bass, collected 12/02/36). Gross Alpha and Gross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. Potassium-40).

All fish data for Strontium-90 and Strontium-39 were below the detection limits of 0.20 pCi/g and 0.30 pCi/g, respectively.

Results of Gamma Spectral Analysis may be found in Tables XXIll, XXV, and X XVII.

8.7 Milk O Milk samples were collected monthly from two locations, the Green Farm and the Schneider Farm. No samples were collected from' Schneider . Farm during November and December; the cows and goats were dry. The Green Farm supplied cow's milk while the Schneider Farm provided both cow's milk and goat's milk. Analyses for loc'ine-131, Elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVill and XXIX present results of these analyses.

Iodine-131 was detected in none of the milk samples during this period.

All of the milk samples collected during the fourth quarter were below the detection limit of 2.0 pCl/l for Strontium-89 and below the detection !!mit of 1.0 pCi/l for Strontium-90.

No gamma-emitting isotopes of interest were detected in any of the milk samples.

8.8 Vegetation Vegetation samples were collected from sampling locations during the fourth quarter of 1936. Vegetation samples consisted of cabbage, mustard greens, and turnip greens collected from the Hazlett, Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha, Gross Beta, lodine-131 and by Gamma Spectrometry. Results are presented in Tables XXX and XXXI.

Gross Alpha activity ranged from less than the lower limit of detection (0.3 pCi/g) at the Hazlett Farm (CA-FPL-V3, Turnip Greens) on 10/13/36, to a high of 0.710.1 pCi/g at the Hazlett Farm (CA-FPL-V3, mustard greens) on 11/10/36.

These Gross Alpha activities are consisent with the levels found in the preoperational monitoring.

Gross Beta levels observed in the vegetation sampics ranged from 5.31 0.1 pCi/g to 17.230.2 pCi/g.

No gamma emitting isotopes of interest were detected in the vegetation samples collected during the fourth quarter 1936.

SUMMARY

i Environmental information on the condition of vegetation at the Callaway site during the second year of plant operation was developed through infrared aerial photography, photointerpretation and ground truthing of stressed vegetation, vegetation mapping and phytopathological diagnosis of stressed vegetation during July and August, 1986.

Ten terrestrial study plots were photographed with infrared film at a scale of 1" = 250'. Residual lands were photographed at a scale of 1" N . = 1000' . Photointerpretation was performed based upon the differential infrared reflectance characteristics of healthy versus stressed tree cover. The infrared photographic record was then verified with a grouno truthing field inspection. On-site and laboratory phytopathological diagnoses were made for stressed vegetation identified from aerial pho.

t'ography. A vegetation map was produced to show the location of stressed vegetation.

No evidence of the ef fects of drift from the cooling tower was found. Vegetation stress in the vicinity of the plant site was found to ,

be caused by natural factors such as oak wilt, Dutch elm disease, root and butt rot and dieback due to unfavoraDie edaphic and meteorological j conditions. No distributional pattern of these diseases was identified during the study. Therefore, the foliar disease found in the Callaway vegetation during 1986 can be directly attributed to natural causes and not to operation of the Callaway cooling tower.

1.0 INTRODUCTION

s 1.1 Purpose Union Electric Company (UE), in response to Nuclear Regulatory Commission (NRC) mandate, has undertaken a program to monitor the poten-tial impacts of cooling tower drif t on the local flora surrounding the UE Callaway Plant in Callaway County, Missouri. The goals of the program are to establish a record of bast.line and operational phase vegetation conditions at the Callaway Planc site using color infrared aerial pho-tography, to document any naturally occurring vegetation stress, and to

' detemine if any vegetation damage can be attributed to operation of the cooling tower. Interpretation of aerial photographs was used to prepare this information. This was supplemented by ground truthing to assure accurate interpretation of photographs and field phytopathological assessment to identify the causes of any vegetation stress encountered.

Using these investigative methods, preoperational baseline environ-mental information on the condition of vegetation at the Callaway Plant site was developed during July and August,1984. Observations during the a

first year of plant operation were made during Augu.t 1985. During July ,

and August, 1986 monitoring was performed to assess the condition of vegetation during the second year of plant operation. The results of these three years of monitoring complement other vegetation monitortng undertaken at the study site. Prior to the present program of infrared i

1 uerial photographic inonttoring, classical field botany techniques were

( 2.2 Photointerpretation Analysis of color infrared aerial photographs for the presence of vegetation stress t$ based upon the changes in infrared foliage reflec-tance that occur as a result of plant stress. A number of technical sources describe the theory and application of color infrared vegetation analysis and were used as a guide for the photointerpretation in this study. Plants under stress due to insect attack, disease or environmen-L tal conditions such as drought exhibit discoloration of their folialje on y

color infrared film because of loss of reflectance. This decrease of infrared reflectance occurs when normally highly reflective spongy leaf

, meso' phyll cells collapse because of plant stress (Colwell, 1956).

Vegetation color atfferences can be used to make inferences about plant vigor (Murtha, 1982; Barrett and Curtis, 1976). Healthy deciduous trees are highly reflective of infrared vegetation and appear as red and magenta in color infrared photographs. Evergreen pines and cedars at the site appear in shades of reddish gray. Stressed vegetation, with leaf yellowing apparent in nomal spectral color photography, appears in sha-des of mauve, blue-grey, yellow and white in color infrared photography.

When vegetation is dead and dry, it appears as yellow and tan on color infrared photography. ,

Using these dif ferential reflectances as signature guides, examina.

tion of photographs was perfomed with simple magnification. Trees that were possibly in stressed condition were marked on photographic prints for subsequent ground truthing.

o 2.0 STUDY METH005 M

Applied Biology, Inc. ( ABI) acted as coordinator for the infrared aerial photo-graphy, photointerpretation and ground truthing of stressed vegetation, vegetation mapping and phytopathological assessment of stressed vegetation conducted at the Callaway Plant site in 1986.

2.1 Aerial Photography ,

Aerial photography for this project was flown from 0921 to 1012 hours0.0117 days <br />0.281 hours <br />0.00167 weeks <br />3.85066e-4 months <br /> on 21 July 1986 by Walker and Associates, Inc. of Fenton, Missouri.

No cloud cover was present. Atmospheric conditions were haze- and dust-free. Color infrared film was exposed in a Wild RC 8 precision aerial mapping camera with 6 inch focal lens. Ten one-hectare terrestrial study plots were photographed with 60 percent forward overlap at a scale of 1"

250'. The residual lands of the plant site were photographed with 60 percent forward overlap and 30 percent side overlap at a scale of 1"

1000'. Overlapping of photo frames is used to assure adequate coverage -

that avoids any visual distortion or loss of infrared photograph bright-ness that may occur along the edges of an aerial photographic exposure.

2.3 Ground Truthing Ground truthing of stressed vegetation was a process of locating (with the aid of aertal photographs and topograpntcal maps) potentially stressed trees recorded on aerial photograph prints. The condition of r- these trees and the assessment made during phytopathological investiga-b.q 8

tions were then correlated with the infrared photographic signature in order to identify stressed trees. Ground truthing took place on 20 and 21 August 1986.

p 2.4 Vegetation Mapping L~ .

After photointerpretation and ground truthing, the locations of stressed or dying trees were plotted on a map of the Calliway Plant site at a scale of 1" = 2,000' (Ftgure 1). In areas of Isolated tree damage Individual stressed or dying trees were represented by an astectsk (*) on the vegetation map. Areas with relatively high densities of stressed or

. ]rm dying trees were represented as shaded damage zones. A considerable I_

% number of the trees that were plotted on the site vegetation map were y inspected for photointerpretation ground truth correlation and phyto-pathological appealsel.

2.5 phytopathological Investigations Individual trees that were located at the Callaway site from aerial photograph plotting were appraised by plant pathologist Barbara S. Lucas of Columbia, Missourt. The purpose of this appraisal was to provide diagnoses of the causes of vegetative stress found on specimens at the a

-h study site. The causes of plant stresses were categortzed as environmen-

, tal, disease, or insect. Plant species vary ,tn their tolerance of, or sensitivity to, adverse conditions brought about by any of the above categories. It is pertinent to note that stress symptoms in plants, especially trees, can be very similar among the categories of causes men-tioned above.

Freezing and thawing, drought, flooding, lightning damage, chemical l Injury, mechanical 1,. jury, or high winds are all examples of environmen-tal conditions that can result in stressed plants. These conditions may cause outright death of plants or may stress them to a paint where they

, are unable to withstand invasion by secondary disease organisms or insect pests.

Diseass is a conditton in plants brought about as a result of inva-slon of plant tissues by other living microorganisms. Primary diseases, such as Oak wilt and Dutch elm disease (DED), are caused by microorga-nisms that can invade healthy plant tisues. These organisms consume p plant-supplied water and nutrient reserves for their own growth, therby L~ creating a stress on the plant. Seconda ry diseases, such as maple decline, are caused by " disease complexes" that usually occur on plants L~

that have already been stressed from other causes. Disease complexes are generally caused by microorganisms that by themselves cannot invade tissues of healthy plants. When plants are stressed, however, their nor-I i mJI resistance to invasion by in3ect and disease organisms is lowered.

The oisease.comples organismi then are able to invade plant tissues.

• clusing further stress and/or death of the plant.

I

FO k Insects may cause direct or indirect damage to plants that may

, result in stress. Direct damage usually is a result of feeding on plant parts such as leaves, bark (cambial layers), wood, or roots. Ov1 position (egg-laying) is anuther type of direct damage that can restrict the flow of water or nutrients in the plant. Insects may also cause indirect damage by serting as vectors of disease-causing organisms; insects feeding on diseased plants inadvertently carry spores of disease orga-nisms to healthy plants.

The elements that were analyzed during diagnosis of stressed tree specimens were: history of forest management practices or herbicide application, site edaphic conditions, condition of surrounding vegeta-tion, recent meteorological record, and inspection of tree leaves, branches, bark and roots. In addition to field observations, standard culturing procedures using twigs and small Oranches were carried out in the laboratory in 1984 in an attempt to recover the causal fungus in cases of suspected fungal infestation. Samples were plated on two

, culture media: 1) oak wilt agar (Nutrimigen base) and 2) acid potato-dextrose agar. These laboratory procedures were inconclusive in 1984 and were not repeated in 1985 or in 1986.

( ) 3.0 RESULTS AND O!SCUSSION V

3.1 _Photointerpretation and Ground Truthing u

,q Analysis of color infrared aerial photographs indicated that the

] vast majority of deciduous trees at the Callaway plant site were in good j health as indicated by their intense magenta reflectance.

r Certain deci-duous trees observed across the study site displayed somewhat lighter magenta or pink coloration or a light fringed appearance on infrared aerial photographs. Ground truthing revealed these trees to be species such as red maple (Acer rubrum), sycamore (platanus occidentalis), per.

simmon (Olospyros virginiana) and mulberry (Morus rubra) that were in good health. Such trees possess a somewhat di f ferent infrared color signature than the deep magenta of the oaks and hickorles that are demi-L]

nant at the Callaway site. Deciduous trees that showed signs of stress reflected in shades of itght pinkish mauve, grey and tan on infrared pho -

tography. These deciduous trees were plotted as individual stressed or dying trees on the site vegetation map (Figure 1). The distribution of these trees showed no apparent pattern. Ground truthing and phytopatho-logical examination revealed that a variety of stress factors (detailed

' in Section 3.2) were affecting these trees. Southwest of the plant site, .

two areas with relatively high densttles of stressed, dying or dead dect-duous trees were coserved on the aerial photographs. These areas were recorded as tree damage zones on the site vegetation map. Fleid inspec-

.R tion revealed that these zones were subject to forest management prac-tices CJerled out by the Missourt Department of Conservation in which 9

'O F

t less robust tree specimens or undesired species were girdled by chain saw cutting. The culled cead and dying trees appeared as stressed aggrega-tions on infrared aerial photography. At the smaller of these two tree damage zones, numerous trees appear as whitish, barren trunks on infrared

[J L

aerial photography. These dead trees have been left standing on this I site for some time and have been noted in the two previous annual reports L

I on aerial photographic vegetation monitoring at the Callaway site. At the larger of the two tree damage zones, trees that were recently girdled and still bear dying leaves displayed yellowish tan infrared reflectance on aerial photographs.

i Healthy eastern redcedar (Juniperus virginiana) and plantation grown white pine (pinus strobus), both evergreen species, displayed reddish

[

( gray coloration in infrared photography. The only stressed white pines that were apparent on aerial photographs were a few specimens located in a cultivated stand just northwest of the complex of power plant buildings. The stressed pines displayed tan infrared reflectance. As a

' ~

whole, the stand of white pine was in fairly good condition but with some lower branch dieback, perhaps due to crowding and sunlight shading.

Northeast of the plant site a single redcedar, located in an open field, was observed to be in a stresssid condition with yellowish tan reflectance '

being noted on aerial photographs. Eastern redcedars were in good con-dition across the study site in general.

3.2 Phytopathological Investigations Oak wilt, a vascular disease caused by the fungus Ceratocystis fagaceacum, was diagnosed as the cause of stress in a number of oak spe-10 l

l

r-,s

[ } cimens. These trees were either black oak (Quercus velutina), white oak (Quercus alba), or shingle oak (Quercus umbricaria). Diagnoses were E ;

t based on symptom expression in the field. Symptom development begins in p the upper crown of infected trees. Leaves exhibit marginal scorching, a Ld' moisture stress symptom, and often fall from the tree. Leaf scorch symp-4 toms develop because the fungus multiplies in the vascular system, effec-tively blocking the uptake of water. The disease develops rapidly in the red oak group (which includes black oak and shingle oak), spreading I

throughout the entire tree. Infected trees in this group are often j killed in a single season. Disease development in white oaks is much slower. Symptom expression is usually confined to a few branches each i a yeal. White oaks decline over a period of several years.

Once a tree dies, the fungus produces mycelial mats underneath the outer bark. The mycelial mats, or " pressure pads", often split the bark, exposing the pad surface upon which spores are produced. The spores have a fruity odor that is attractive to the sap- and bark-feeding beetles that vector the fungus to healthy trees. Pressure pads are formed in the late summer of death if adequate moisture is available. If moisture is limiting, pads may not form until early spring if at all (Boyce,1957; Tainter and Gubler,1973). Invasion of the oak-witted trees by secondary ,

disease organisms inhibits pad formation (Shigo, 1985; Tainter and Gub le r , 19 73) .

Dutch elm disease (DED), caused by the fungus Ceratocystis ulmi, was identified as the stress factor on American elm (Ulmus americana) trees, f

L. r w While it is impossible to determine the exact cause of the decline, such symptoms are of ten indicative of a root problem. When the root system is not functioning sufficiently to meet the needs of the above-ground parts, decline begins. Branch di eback is often the tree's attempt to j reestablish the balance between roots and shoots. Some of the root

!. problems that can lead to decline are: reduced oxygen in compacted soil, destruction of fine roots from extended drought, root rats, or site disturbances that physically damage roots.

M The stressed condition of a number of oak trees was attributed to locally unfavorable edaphic conditions. These trees were found growing on slopes or ridges with shallow gravelly soil. On these sites, tree and shrub growth was thin and less vigorous than generally observed; ground cover was sparse. This habitat appears to be marginally suited for good vegetation growth. The occurrence of very hot, dry summers and severe cold winters over the past several years could cause trees growing in such a habitat to eventually exhibit decline and dieback symptoms.

Edaphic factors also combine with site temperature and rainfall characteristics to affect vegetation health. The US Department of Agriculture Soil Conservation Service classifies the three most commonly '

observed soil types of the study site as Calwoods, Gorin or Mexico silt loam. The subsoil of each type is a relatively deep (9 to 79 inches) silty clay or clay overlain by a shallow (3 to 7 inches) topsoil of silty loam or silty clay loam. Permeability to water and available water capa-city of these soils are the primary characteristics that affect plant 13 i l

]i Diagnoses were based on visual symptoms: wilting, dieback of branches, and discoloration of the vascular system. OED is a vascular disease similar to Oak wilt. It has been devastating on Merican elm (Ulmus and other native species because it is caused by an americana)

" introduced" pathogen against which our native elms have not developed

- .q J genetic resistance.

A third disease that was encountered was root and butt rot. Root and butt rot was observed on plantation grpwn white pine (Pinus strobus) and walnut (Juglans nigra). Root and butt rots are caused by a variety y

,j of fungi capable of attacking healthy trees and killing the roots and the living bark of the lower trunk. Many of the root and butt rot fungi sur-M vive as saprophytes in cut stumps. iney utilize the stump as an energy source for growth through the soil until a healthy root is encountered.

GJ Above-ground symptoms These rots are therefore common in logged areus.

of root and butt rot are expressed as branch die-back and sparse, of f-color foliage. Fruiting bodies (basidiocaps) of the causal fungi, when they occur, are usually formed in the fall. Decay and discoloration and fungal mats can be observed at the base of the trunk and on large roots just under the soil surface, g

A number of tree species, including hackberry (Celtis occidentalis),

red, black and white oaks (Quercus rubra, h velutina and S alba) and i Merican, elm (Ulmus americana), exhibited symptoms of dieback and decline. The dieback and decline symptoms varied with the species but in i general were thinning crowns, small pale foliage and branch di eback .

growth. Each soil has a large water holding capacity but also a low per-meability to water and low available water capacity. With ample precipi-tation these soils absorb large quantities of water and because of their low permeability rates can become waterlogged. Waterlogged soils are poorly aerated; that is, they have low oxygen concentration. Low oxygen concentration has adverse effects on root growth by inhibiting the uptake of water and nutrients and may produce stresses similar to drought or I physical damage, resulting in wilting or chlorosis. Additionally, restricted root growth can result in an accumulation of toxic metabolites that interfere with defense reactions of the host plant (Schoeneweiss, 19751 1

Alternately, during the hat, dry summers such as occurred in 1980, 1983 and 1984, these soils began drying and, as they are composed of a high percentage of clay particles that tenaciously bond to water molecu-les, water was much less available to plants. In periods of high

[ transpiration, plants growing in these types of soils generally cannot absorb and translocate sufficient amounts of water to continue normal, or in some cases even sustainable, growth rates. Thus they may become dehydrated, wilt and possibly die.

In general, climatic condi tions in the vicinity of the Callaway plant from October 1985 through August 1986 consisted of a relatively moderate winter, spring and summer when compared to 30-year averages (Table 1).

nj taring. This observation is consistent with the more favorable meteoro-logical conditions recorded during the past year, since such diseases are

, usually fos tered by overly damp climatic conditions during spring and summer months.

A summary of site observations is presented below: -

Site 1 Only one black oak with active oak wilt symptoms (leaf scorch and t

defoliation in the crown) was observed on this site in 1986. Although there were a number of dead standing trees, the oaks in general were in better condition than in 1984 and 1985.

One dead shagbark hickory was also noted on this site.

Site 2 The oaks on this site were rated in good condition, but with some thinning in the crown. No active oak wilt symptoms were observed.

N Red maples exhibiting leaf dieback and early fall coloration (slide *

1) were found to have been girdled as part of a timber management project conducted by the Missouri Department of Conservation.

, Site 3

\ The fencerow of hackberry on this site has declined considerably o since 1985. Branch dieback was prominent, and the remaining foliage was 16

g 4

smaller than normal (slides 2 and 3). A mosaic pattern of green and healthy tissue and insect galls was evident on the leaves. These con-ditions are part of a general dieback and decline syndrome.

Symptoms of Dutch elm disease were noted on one Merican elm (slide 4).

A large ash and a red oak were exhibiting diebock and decline symp-4 tous (slides 5 and 6).

i Site 4 f

The condition of black walnuts on this site has not changed noti-ceably since they were first observed in 1984. The foliage remained pale and sparse (slide 7). These trees are planted too deeply in the soil and are suffering from butt rot.

The condition of an old Merican elm had not changed from 1985 l (slide 8). The tree is growing in shallow soil with a number of its

! roots exposed at the surface of the ground. Due to site-related environ-mental conditions and the old age of this tree, natural dieback and ,

c decline is occurring.

l Two fungal diseases, anthracnose and leaf blotch, were evident on young hickory (slide 9). The diagnosis was verified by a brief microsco-

, pic examination. The symptom of anthracnose is a large, irregular necro-

in mid-Missouri.

Both diseases are common on hickory M

Site 5 rs Although black ' oak exhibited leaf scorch, ea-ly defoliation and the I

vascular browning suggestive of oak wilt, the primary problem with the oaks at this site was dieback and decline. Two individual white oaks and

.l.

r two black oaks were as'essed.

s The stress symptoms on each were scattered

[]a branch dieback and top dieback (slide 12).

,In an old field adjacent to Site 5, the effects of the herbicide Tordon (picloram) were noted on honeylocust. The herbicide had been applied by the Missouri Department of Conservation prior to 1984 for selective control of honeylocust and multiflora rose.

A single large eastern redcedar growing in the old field was dying from an undetennined cause (slide 13).

Site 6 The stressed oaks on this site were in varying degrees of decline, ,

• I ranging from scattered branch dieback in progress to trees that had completely died earlier this season (slides 14,15 and 16). These trees l

l- I were found on slopes with shallow, rocky soils that probably contributed i

to the observed decline symptoms.

tons of oak wilt in 1984 and 1985 remains unchanged from last year. One half of the tree remains alive (slide 20). Red and black oaks in this area are in varying states of decline due to the effects of environmental stress (slides 21 and 22). The area where the decline symptoms were most 1-l evident was a shallow, rocky, exposed slope (slide 23). There are l

healthy oaks nearby (slide 24).

Site 9 The two individual stressed trees in this area were silver maples growing on an old nome site. Stress symptoms were top dieback, broken branch stubs and stripped bark (slides 25 and 26).

19 i

Three catalpa trees had declined since 1985. Mechanical injury to bark and trunk was determined to be the cause of this decline. The pri-ma ry foliage was pale green in color and branch di eback was evident.

Stump sprouting was extensive, with the sprouts being a much healthier

} green color than the primary foliage (slides 27 and 28).

hf A number of trees currently affected or already heavily stressed or dead as a result of Dutch elm disease were noted on this site,(slide 29).

A large ash with yellowed foliage at the branch tips was detected.

Numerous oviposition scars from last year's periodical cicada were evi-

. dent 'on the understory; therefore, girdling from this insect damage was thought to be the specific cause of stress for this tree.

A second ash with overall decline symptoms was examined. This tree was first observed in 1984 and has not declined significantly since then (slides 3'O and 31).

)

The most notable problem on this site was a disease of the ash j saplings in the understory. The problem was diagnosed as a fungal twig canker (slides 32, 33 and 34). .

Site 10 No stressed trees were. observed in the vicinity of this site.

4.0 CONCLUSION

S l

The number of oaks with oak wilt symptoms was less in 1986 than in the two previous years. Most of the oaks showing stress symptoms in the infrared photos were trees that had di ed recently. The dead leaves

, remained attached as opposed to oak wilt, with which defoliation of the upper crown begins in early summer. The exact cause of death of these l trees cannot be determined, but is likely due to the combined effects of poor site conditions and environmental stress.

1 Common foliar diseases were evident on hickory and hop hornbeam.

Other diseases noted were Dutch elm disease, an unidentified twig canker of ash saplings, and root and butt rot of white pine.

No directional patterns of stressed vegetation were noted, and no stress symptoms were found to be due to the effects of drift fecm the cooling tower.

Most of the deciduous tree cover at the Callaway site is healthy and reflects intense magenta on infecred aerial photography. Those specimens ,

that are stressed or dying are recognizable en color infrared photography because of their mauvish pink, grey or tan reflectance. The largest number of these stressed or dying trees occur in two tree damage zones in i

l which a forest management program is carried out by the Missouri Department of Conservation. In these areas the less robust tree speci-9 mens were chain saw girdled for the purpose of selective stand thinning.

f 21

1O Most evergreen species at the study site (white pine and eastern redcedar) are in good condition and are recognizable by their reddish grey infrared reflectance. Stressed evergreens are apparent because of their tan infrared reflectance.
