{{#Wiki_filter:. N w/ INTRODUCTION 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 1985 and the environmental evaluations for plant modifications completed during 1985. The first section of this report summarizes and inter-prets the results of the radiological environmental moni-toring program conducted in accordance with Technical Spec-ification Section 3/4/12. Section 2 describes the nonradio-logical 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 Speci-fication and Appendix B to the Callaway Plant Operating License. CONCLUSION The first section of this report contains all the radiological environmental monitoring conducted in the vicinity of the Callaway Plant during 1985. The comparison of the results of the radiological environmental monitoring conducted during 1985 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 1985 is contained in Section 2 of this report. The monitoring conducted during 1985 showed no evidence of effects of drift from the cooling tower. The foliar disease found in the vegetation during 1985 could be directly attributed to natural causes. There were no plant modifications completed during 1985 with an unreviewed environmental question as shown in Section 3 of this report.

Abstract The Radiological Environmental Monitoring Program is an ongoing study conducted by Controls for Environmental Pollution, Inc. (CEP) for Union Electric Company (UEC), Callaway Plant, Unit 1. This report is a summary of all data obtained from samples collected by UEC personnel during 1985. The monitoring program provides a comprehensive environmental analysis of radiological activity in the area surrounding the Callaway Plant Site. CEP analyzed the following types of samples: air particulate and radiciodine, ground water, surface water, milk, washload sediment, bedload sediment, bottom sediment, shoreline sediment, fish, vegetation, soil and direct radiation (TLD). A statistical analysis and graphic presentation for all analytical results for samples O collected during 1985 are included in this summary report. Possible trends and anomalous results, as interpreted by CEP are also discussed. l I 1 0 1 i _ _. . . . .. .- .- ~ ---- - - - -
1.0 Introduction' g This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during 1985 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 dete.mine 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 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 2,1984. O
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 lYant area. Prior to this time, all analyses were performed by Radiation t Management Company. I UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected were: milk, surface water, groundwater, shoreline sediment, I bottom sediment, bedload sediment, washload sediment, soil, fish, vegetation, airborne particulates, airborne radioiodne 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 O 1985. l l 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. The levels and fluctuations of radioactivity detected in the samples collected around the Callaway Plant were consistent with previously accumulated environmental data.
( For this reporting period there are no measurements exceeding reporting levels, or g analysis in which the detection limit was not achievable. 3.1 Airborne Particulates and Radiciodine Airborne particulate samples were collected from fourteen monitoring stations during 1985. All of the air particulate samples were analyzed for Gross Beta activity. Gamma Spectrometry, Strontium-89 and Strontium-90 analyses were performed on quarterly composites from each station. Seven of the airborne particulate stations were also sites for airborne radioiodine. The range and 1985 annual mean Gross Beta activity at each of the sampling locations follows. Measurements are in pCi/m3.

Graphic presentations of the Weekly Cross Beta activities for each collection location are presented in Figures I through 14. Invalid samples are those with anomolous Gross Beta activity due to air sampler malfunction (i.e. hour meter malfunction, sampler g l l
malfunction, etc.) or other circumstances which may have compromised the C sample init grity. Figure 15 presents the Mean Weekly Cross Beta for all collection locations. The lowest Mean Weekly Gross Beta activity (0.01310.001 pCi/m3) was observed from 03/28/85 - 04/04/85 while the week exhibiting the highest activity occurred 11/27/85 - 12/05/85 (0.06410.088 pCi/m3). Mean Quarterly Gross Beta activities were as follows: oCi/m3 January - March 1985 0.023 1 0007 April - June 1985 0.017 1 0003 July - September 1985 0.021 1 0005 October - December 1985 0.029 1 0012 l O Strontium-90 was detected in four of the quarterly composite samples during . 1985 (See individual Quarterly Reports). Strontium-90 activity ranged from less than 0.002 pCi/m3 to 0.00230.001 (Second Quarter 1985). No Strontium-89 was detected in any of the quarterly composite samples from 1985 (Detection Limit 0.005 pCi/m3).
)
l 1 i 1 Gamma-emitting nuclides of interest detected in quarterly air- particulate composites include Cesium-137 and Beryllium-7. (See individual quarterly reports). l Airborne radiciodine was below detection limit (0.005 pCi/m3) in all samples collected during 1985. O

r n l 3.2 Thermoluminescent Dosimetry bm Thermoluminescent 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 containing copper backing to shield out low energy radiation. The TLD's were placed at 52 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 28. ur/hr January February 3.0 i .2 1 10.6 170

- Invalid Data Figures 16 through 27 present the ur/hr values obtained for each TLD station collected during each month of 1935.
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 x-ray of the packaged TLD's during transit to the site from CEP. Evidence to support this conclusion includes the fact that exposure level in areas I and 2 of the TLD badges were higher than areas 3 and 4. This would indicate exposure of the TLD's to low energy x-rays. In addition, there were two February TLD's left in the field that were collected during March and showed normal exposure results. Annual TLD's were placed in the field on August 29, 1984 and were collected on g December 23, 1985. Data appearing in Table I is the result of reading and averaging the four quadrants of each TLD chip. Transit controls dosimeters were used to determine the dosage received during shipment and were substracted from the gross readings obtained for each monitoring site. Due to the length of time the annual TLD's were exposed to the elements, five stations had missing TLD's (CA-IDM-09, CA-IDM-15, CA-IDM-28, CA-IDM-29, and CA-IDM-41).

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. A summary of the Mean Gross Alpha and Cross Beta activities for Well Water samples may be found in Table II. Collection location DOI (5.1 mi SE, Holzhouser Crocery Store / Tavern) had Gross Alpha activities ranging from less than 2.0 pCi/l to 6.511.9 pCi/l (collected 02/19/85) with an annual mean Gross Alpha activity of 3.211.9 pCi/1. Gross Beta activities from this collection location ranged from less than 3.0 pCi/l to 13.610.8 pCi/l (collected 11/12/85) with a 1985 mean Gross Beta of 3.613.6 pCi/1. A graphic presentation of the monthly Cross Alpha and Gross Beta results for well water samples obtained from collection location DOI may be found in Figure 29. A Strontium-90 activity of 1.0 0.7 pCi/l was detected in the Well 1 $ Water sample from collection location DOI, 06/l'J/85. No detectable levels of Tritium or Strontium-89 were observed in any of the well water samples collected at Site DOI during 1985. Gross Alpha activities at collection location F05 (1.0 mi SSE, Onsite Groundwater Monitoring Well) ranged from less than 2.0 pCi/l to 3.81 1.4 pCi/l (collected 07/08/85). The 1985 mean Gross Alpha activity for Site FOS was 1.71 1.1 pCi/1. Gross Beta activities at collection location FO5 ranged from less than 3.0 pCi/l to 18.8 12.3 pCi/l (collected 06/10/85) with a mean annual Gross Beta activity of 11.3 15.4 pCi/1. Figure 30 graphically presents the monthly Gross Alpha and Gross Beta activities for co!!ection location FOS. All well water samples from collection location F05 were less than 500 pCi/l for Tritium activity and less than 1.0 pCi/l for Strontium-89 activity. Strontium-90 detected h (] in one 1985 Well Water sample (2.0 1 0.7 pCi/1, collected 06/10/84). All other samples collected at Site FO5 during 1985 were less than 0.5 for Strontium-90.' Figure 31 illustrates the monthly Gross Alpha and Gross Beta activities for all Well Water samples collected from site FIS (0.55 mi NE, Onsite Groundwater Monitoring Well) during 1985. Gross Alpha activities ranged from less than 2.0 pCi/l to 4.6 1.7 1 pCi/l (collected 02/19/85) with a mean annual Cross Alpha activity of 2.1 11.2 pCi/1. Gross Beta activities ranged from less than 3.0 pCi/l to 8.810.7 pC1/1 (collected 07/08/85). The mean annual Gross Beta activity for FIS was 5.81 2.2 pCi/l. All Well Water samples collected at Site FIS were less than the detection limits for Tritium and Strontium 89, (500 pCi/l and 1.0 pCi/l respectively). Strontium-90 was detected in one 1985 Well Water sample collected from FIS. A Strontium-90 activity of 1.8 10.7 pCi/l was detected in the sample collected 06/10/85. Overall, the 1985 mean annual Cross Alpha activity for all Well Water samples was 2.311.5 pCi/1. A 1985 mean Gross Beta activity for all Well Water samples was calculated to be 6.915 0 pCi/1. No gamma-emitting nuclides of interest were detected in any of the Well Water samples collected during 1985. The January Well Water samples were not collected due to an oversight in the sample collection schedule. To prevent recurrence, the sample collectors were informed of the importance of sample collection, and a system for independent verification of sample collection by Nuclear Engineering was initiated. i

- 3 3.4 Surface Water g
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 S01 (4.8 mi SE, 84 feet upstream of discharge, North Bank) yielded a 1985 annual mean Gross Alpha activity of 4.21 3.0 pCi/l with a range from less than 2.0 pCi/l to 9.6 1 7.3 (collected 07/04/85). The mean annual Gross Beta activity for 501 was calculated to be 13.01 4.7 pCi/l with a range of Cross Beta activity from 7.510.7 pCi/l to 22.211.0 pCi/l (collected 06/04/85). The monthly Cross Alpha and Gross Beta results are graphed in Figure 32. Strontium-90 was detected in one Surface Water sample h co!!ected during 1985 from collection location 501 (2.410.7 pCi/1, collected 06/04/85). No Strontium-89 activity was observed in any of the Surface Water samples collected from location 501 during 1985. During January, February, and March, collection location 501 indicated Tritium activities of 12781 569 pCi/1, 95251 725 pCi/1, and 10611 636 pCi/l respectively. An investigation concluded that these three samples had been cross contaminated during collection. No other Tritium activity above detection limit (500 pCi/1) was detected at 501 for the remainder of 1985. 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 10.51 3.4 pCi/l (collected 07/04/85). The 1985 mean Cross Alpha activity from
p v this location was 3.712.9 pCi/1. An annual mean Gross Beta activity of 12.315.4 pCi/l was observed while the range of Gross Beta activity from this site was from 4.811.0 pCi/l to 22.2 11.0 pCi/l (collected 06/04/85). ligure 33 shows the monthly Gross Alpha and Gross Beta results graphically. Strontium-90 was detected in one Surface Water sample collected during 1985 from co!!ection location 502 (1.410.7 pCl/l collected 06/04/85). All Surface Water samples collected from location 502 during 1985 were less than the detection limits for Tritium and Strontium-89 (500 pCi/l and 1.0 pCi/1, respectively). Figure 34 presents the monthly Cross A!pha and Gross' Beta results for samples collected during-1985 from collection location SO3 (68 mi E, City _ of St. Louis Water Intake). A range of Gross Alpha activity from less than 2.0 pCi/l to 5.312.2 pCi/l (collected 03/14/85) was observed in the samples collected from O iocetiom so>- The 1985 meem cross ^igae ectivitv rer se-pies <<om tais location was calculated to be 2.711.7 pCi/1. Results of Gross Beta analyses for Surface Water samples from Location 503 ranged from less than 3.0 pCi/l to 21.412.3 pCi/1. A 1985 annual Gross Beta activity of 10.2 16.1 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 locatios during 1985. The 1985 mean annual Gross Alpha and Gross Beta activities for all Surface Water samples were 3.51 2.6 pCi/l and 10.216.1 pCi/1. No gamma-emitting nuclides of interest were detected in the 1985 Surface Water samples. During 1985, the upstream surface water samples and downstream surface water l samples from January to August were daily grap samples composited over the month due to continuous maintenance problems with the composite water samplers. To reduce the out of service time for these samplers, the following changes were implemented: 1) the priority for maintence work on the samplers O was upgraded, 2) modifications were made to the downstream sampler to reduce silt build-up problems, and 3) a redesign of the upstream composite sampler to eliminate the air lift pump will be completed in 1936.

() Five species of fish were collected on a monthly basis from the same locations on the Missouri River as the sediment samples. Fish samples were not collected from location A and C during January due to the extremely cold weather conditions and ice in the river. Species of fish collected during 1985 include freshwater drum, bigmouth buffalo, smallmouth buffalo, black buffalo, carp, goldeye, river carpsucker, highfin carpsucker, paddlefish, shorthead redhorse, American eel, shortnose gar, longnose gar, gizzard shad, blue catfish, channel catfish, flathead catfish, quillback, largemouth bass, striped bass, white bass, black crappie, white sucker, blue sucker and white crappie. Gross Alpha, Cross Beta, Strontium-89, Strontium-90 and Gamma Spectral analyses were performed on all fish samples. All results are in terms of pCi/g (dry). The 1985 mean annual Gross Alpha and Gross Beta activities for each sampling location are p v summarized in Table V. The monthly Cross Alpha activities in F4sh samples collected from Location A (4.9 mi SSE,0.6 river mile upstream of discharge, North Bank) ranged from less than 0.3 pCi/g to 0.4 10.2 pCi/g (Carp collected 12/12/85) with a 1985 Annual Mean Gross Alpha activity of 0.210.1. Gross Beta activities in these samples ranged from 1.810.1 pCi/g to 8.310.2 pCi/g (Carp collected 06/24/85). The mean annual Gross Beta activity for 1985 Fish samples collected at Location A was 4.611.7 pCi/g. Figure 44 is a chronological presentation of all Gross Alpha and Gross Beta activities for 1985. Strontium-90 was detected in two fish samples collected in 1985 from Location A. The range of Strontium-90 activity in all fish samples co!!ected from Location A was from less than 0.02 pCi/g to 0.4810.21 pCi/g (Freshwater Drum, collected 03/19/85). O V No Strontium-89 was detected in any 1985 Location A Fish samples. Gamma-g emitting nuclides were detected in only one Fish sample collected from Location A. The sample collected 09/23/85 had a Cesium-137 activity of 0.1510.07 pCi/g. Fish samples collected from Location C (5.1 mi SE,1.0 river mile downstream of discharge, North Bank) had mean annual Gross Alpha and Cross Beta activities of 0.210.1 pCi/g and 4.911.7 pCi/g, respectively. Figure 45 illustrates the monthly Cross Alpha and Gross Beta activities for Fish collected from Location C. Gross Alpha levels in these samples ranged from less than 0.3 pCi/g to 0.410.2 pCi/g, while Gross Beta levels ranged from 1.61 0.1 pCi/g to 8.210.2 pCi/g (Bigmouth Bufflo collected 04/02/85). No Strontium-90 was detected in any of the Fish from Location C during 1985. No Strontium-89 was detected in any of the Fish from Collection Location C. Only one gamma-emitting nuclide of interest was detected in 1985 Location C Fish, Cesium-137 (0.1091 0.032 pCi/g) in River h Carpsucker collected 03/19/85. Figure 46 graphically presents the monthly Cross Alpha and Gross Beta results for Fish samples collected from Location D. Gross Alpha activities ranged from less than 0.3 pCi/g to 1.110.3 pCi/g (American Eel collected 02/21/85) with a Mean Annual Gross Alpha activity of 0.2 1 0.2 pCi/g for all fish collected from Location D during 1985. Gross Beta ranged from 1.51 0.1 pCi/g to 8.610.2 pCi/g (River Carpsucker co!!ected 07/25/85) with a 1985 Annual Mean of 4.811.7 pCi/g. No Strontium-90 or Strontium-89 activity was observed in any of the fish collected from this location. Cesium-137 and Cesium-134 were detected in Location D Fish during 1985. No l other gamma-emitting isotopes of interest were detected in any of the 1985 1 Location D Fish samples. l l

3.3 Vegetation g Vegetation samples were collected during the second, third and fourth quarters of 1985 from four locations. Samples were analyzed for Gross Alpha, Cross Beta, Iodine-131 and Gamma-emitting nuclides. Gross Alpha activity was detected in seven of the vegetation samples, primarily in samples collected during the second quarter. Levels of Gross Alpha activity ranged from less than 0.3 pCi/g to 0.610.2 pCi/g (Mustard Greens collected from Meehan Farm 05/29/85). The 1985 mean Gross Alpha activity was 0.210.1 pCi/g. Gross Beta activity ranged from less than 1.0 pCi/g to 29.5 10.3 pCi/g (Spinach collected from Hazlett Farm 05/29/85). The mean annual Gross Beta activity of the vegetation samples collected during 1985 was 12.7 1 7.0 pCi/g. lodine-131 was detected in one vegetation sample. The Mustard Greens collected 05/29/85 from the Meehan Farm had an activity of 0.123 0.05 pCi/g. All other vegetation h samples collected in 1985 were below the Iodine-131 detection limit of 0.03 pCi/g. No other gamma-emitting nuclides of interest were observed in any of the vegetation samples collected during 1985. O o 3.9 Soil Soil samples were collected from eleven locations during the fourth quarter of 1985. Soll was analyzed for Gross Alpha, Gross Beta and Gamma-emitting nuclides of interest. Gross Alpha activity in the soil samples ranged from 0.710.1 pCi/g to 1.510.2 pCi/g with an 1985 Annual Mean of 1.010.2 pCi/g. Gross Beta activity ranged from 0.910.1 pCi/g to 1.3 10.1 pCi/g with a 1985 Mean Gross Beta activity of 1.320.3 pCi/g. Cesium-137 was observed slightly above the detection limit in all the 1985 soil samples. The range of Cesium-137 was from 0.4010.03 pCi/g to 1.4710.04 pCi/g. No other gamma. emitting nuclides of interest were detected in any of the soll samples collected during 1985. I O 1

1.0 INTRODUCTION
l In accordance with Technical Specification 3.12.2, the annual (m) Land Use Census within a 5 mile radius of the Callaway Plant was performed during July,1985 by Union Electric Real Estate Department. Observations were made in each of the 16 meteorological sectors of the nearest milking animals (cows ahd goats), nearest residence, and the nearest garden of greater than 2 (500 f t 2 ) producing broad leaf' vegetation. This census was 50m 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 different compass points.

Abstract The Radiological Environmental Monitoring Program is an ongoing study conducted by Controls for Environmental Pollution, Inc. (CEP) for Union Electric Company (UEC), Callaway Plant, Unit 1. This report is a summary of all data obtained from samples collected by UEC personnel during January, February and March 1985. In order to establish background radiation levels in the environment around UEC's Callaway Plant, Unit 1, the following types of samples were collected: air particulate and radiciodine, ground water, surface water, milk, washload sediment, bedload sediment, bottom sediment, shoreline sediment, fish, vegetation, soil and direct radiation (TLD). A statistical analysis and graphic presentation for all analytical results for samples collected during this first quarter 1985 are included in this report. Possible trends and anomalous results, as interpreted by CEP are also discussed. O l.0 Introduction h This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the first quarter of 1985 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. h 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 will be compared with the ,re-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 l pressurized water reactor, which achieved initial criticality on October 2,1984. l O' 2.0 Description of the Monitor *me 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. UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected this quarter were: milk, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radioiodine and direct radiation (TLD). Locations of the monitoring sites are shown in Figures 1 and 2. Table 1 presents the monitoring sites and the respective samples collected. Sample collection frequency for each of the monitoring locations is depicted in Table 11. Meanings of sample type codes used in Table I are as follows: Code Sample Collected AIO Air lodine APT Air Particulate AQF Fish AQS Sediment FPL Leafy Green Vegetables IDM TLD , MLK Milk I SOL Soil > SWA Surface Water WWA Well Water O l

(') V 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 1 micron particulate), is placed into a two-inch stainless steel planchet and counted for Cross Alpha and Gross Beta radioactivity using a low background, internal gas flow, simultaneous proportional counter (Beckman Wide Beta 11), or by using a low background simutaneous counter (Tennelec LB5100). 3.1.2 Gamma Spectrometry The filters are composited according to station and sealed in a small, O plastic Marinelli beaker. The filters are then counted using either a Ge(Li) V 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 The composited filters are dissolved in scid 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. After the ingrowth period has been established it is back extracted into an aqueous phase, precipitated as the oxalate, counted in a low background proportional counter (Beckman Low Beta II), and calculated as Strontium-90 activity. The aqueous phase p is evaporated to a low volume, precipitated with fuming nitric acid, V 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 11) and the Strontium-89 activity is determined by subtracting the previously measured Strontium-90 activity and its corresponding Yttrium-90 ingrowth from '.:ie measured gross Strontium activity. 3.1.4 Iodine-131 3.1.4.1 Alkaline Leach Method The radioiodine is stripped off activated charcoal by reduction using concentrated ammonium hydroxide (NH4OH) and hydrogen peroxide (H22 O ). The charcoal is then filtered and the remaining solution is acidified with nitric acid (HNO3 ) and extracted with carbon tetrachloride (CCl4) to remove the lodine. It is then back g extracted using 0.2% hydrazine 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 iodine (Agl). The dried precipitate is weighed for recovery and counted for Iodine-131 in a thin window gas flow proportional counter (Beckman Low Beta 11) having a forty-one percent efficieacy for Iodine-131 precipitated as silver iodide (Agl). 3.1.4.2 Gamma Spectrometry Method The charcoal canister is placed directly on an intrinsic germanium detector and lodine-131 activity determined using Method 3.1.2. 3.1.5 Direct Radiation Direct radiation measurements were taken using Thermoluminescent h Dosimeters (TL D's). Each dosimeter consists of a Teflon wafer (O v impregnated with twenty-five percent CaSO 4:Dy phosphor. Dosimeters are e annealed in an oven prior to use and are inserted into black polyethylene pouches. The CaSO 4 :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. 3.2 Vegetation 3.2.1 Iodine-131 A suitable aliquot of wet (as received) sample is placed into a small, plastic-Marinelli beaker and Iodine-131 activity determined using Method 3.1.2. 3.2.2 Gross Alpha and Gross Beta A suitable aliquot of prepared sample is muffled, dissolved in dilute acid (7
%J and transferred to a tared two-inch stainless steel planchet. The planchet is counted for Gross Alpha and Gross Beta activity using Method 3.1.1.
3.2.3 Gamma Spectrometry A suitable aliquot of prepared sample is placed into a small, plastic Marinelli beaker and specific nuclides, if present, identified and quantized using Method 3.1.2. 3.3 Milk 3.3.1 Iodine-131 Two liters of milk containing standardized Iodine carrier are stirred with Amberlite IRA-400 anion exchange resin for one hour. Tne Iodine is stripped from the resin with sodium perchlorate (NaCIO4 ) acidified with nitric acid, precipitated with silver nitrate (AgNO3) and filtered on a tared l glass-fiber filter. The dried precipitate is weighed for percent recovery l l and counted for Iodine-131 in a thin window, gas flow, proportional counter l (Beckman Low Beta 11). This instrument has a forty-one percent efficiency l ! L
I l using lodine-131 precipitated as silver iodide (Agl). O' 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. 3.3.4 Elemental Caclium one milliliter of milk is diluted to 100 milliliters and acidified with nitric acid. The diluted sample is analyzed for Calcium using Instruments S.A. Jy-38 Sequential Plasma Spectrom 3.4 Surface and Well Water 3.4.1 Gross Alpha and Gross Beta A suitable aliquot of water is evaporated to dryness and transferred to a tared two-inch stainless steel planchet. The planchet is counted for Gross Alpha and Gross Beta activity as in Method 3.1.1. 3.4.2 Tritium Three milliliters of water sample are mixed with NEF-934 Aquasol cocktail which is manufactured by New England Nuclear Corporation. This gives a l mixture of nineteen percent sample in a clear get type aquaso!. The mixture gives a Tritium counting efficiency of approximately thirty percent. The counting system used is a Beckman LS-100 Liquid Scintillation Spectrometer. Six Tritium standards, certified by NB5, are counted before each set of water samples to check the counting system's efficiency. A counting efficiency is derived from the standards which are O equalin activity but vary in the amount of quenching. 3.4.3 Strontium-89 and Strontium-90 A one liter aliquot of water, containing Strontium carrier, is evaporated to dryness and the residue taken up in dilute acid. Method 3.1.3 is then followed beginning at the ingrowth period. 3.4.4 Gamma Spectrometry A one liter aliquot of the water sample is placed in a plastic Marinelli beaker and specific nuclides identified and quantized using Method 3.1.2. 3.5 Fish 3.5.1 Gross Alpha and Gross Beta Refer to Method 3.2.2. 3.5.2 Strontium-89 and Strontium-90 {} A suitable aliquot of prepared sample is muffled, dissolved in acid, transferred to a 100 mi beaker and Strontium-Yttrium carriers added. The sample is then wet ashed with nitric acid and hydrogen peroxide, taken to dryness and up to volume in dilute acid. Method 3.1.3 is then followed beginning at the ingrowth period. 3.5.3 i.Jimma Spectrometry A suitable aliquot of prepared sample is placed in a plastic Marinelli beaker and specific nuclides identified and quantized using Method 3.1.2. 3.6 Bottom, Bedload and Washload Sediment 3.6.1 Gross Alpha and Gross Beta 4 A suitable aliquot of prepared sample is muffled, dissolved in acid, nitrated, evaporated and transferred to a tared two-inch stainless steel planchet.

l 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). O 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. 8.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this repo-t 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 h 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 Radioiodine Airborne particulate samples were collected from fourteen monitoring stations during the first quarter of 1985. 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. The air particulate samples collected during the week of 01/03/85 - 01/10/85 were inadvertently mixed up in a laboratory accident. The Gross Beta activity for these samples ranged from 0.01210.001 pCi/m3 o t 0.026 0.002 pCi/m3 (based 1 on the mean volume of air sampled for the collection period; 427.3m3). The calculated Gross Beta activities for these samples are excluded from Table Vil and were not included in the mean calculations. The range of Gross Beta activity at each of the sampliig locations follows.

O The highest mean Gross Beta activity during the report period was observed at Site AS, with a mean activity of 0.02710.015 pCi/m3 Mean Gross Beta activities at the other sites varied from 0.02010.008 pCi/m3 at Sites Site A6 and A8 to 0.02710.015 pCi/m3 at Site A5. Mean weekly Gross Beta activities ranged from a low of 0.01510.002 pCi/m3 during the collection periods of 02/21/85 - 02/28/85 to a high of 0.04710.009 pCi/m3 during the collection period of 02/07/85 - 02/14/85. ? l O All results of the airborne particulate composite analyses for Strontium-89 and Strontium-90 were below the detection limits of 0.005 pCi/m3 and 0.002 pCi/m3, respectively.

i d 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 1 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 sustracted from the gross readings obtained for each monitoring site. A V The January and February exposure levels for. all monitoring locations are consistent with the altitude and geology of the area shown in Tables IX and X. All of the March TLD's and the transit control TLD had abnormally high exposure rA levels. We have concluded that this excess exposure resulted from the x-ray of the packaged TLD's during transit to the site from CEP. Evidence to support this conclusion includes the fact that exposure level in areas 1 and 2 of the TLD badges were higher than areas 3 and 4. This would indicate exposure of the TLD's to low energy x-rays. In addition, there were two February TLD's left in the field that were collected during March and showed normal exposure results. 1 .O

3 I V 8.3 Well Water h Well water samples were collected twice from three locations, and analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, and Gamma-emitting nuclides. No well waters were collected during January,1985. Table Xll presents the results of the radiochemical analyses. Gross Alpha activity ranged from non-detectable levels to 6.5 11.9 pCi/1. Gross Beta levels varied from less than 3.0 pCi/l to 10.910.9 pCi/1. Results of Tritium, Strontium-90 and Strontium-89 were below the detection limits of 500 pCi/1,0.5 pCi/l and 1.0 pCi/l respectively for all samples. h Gamma Spectrometry showed no detectable levels of isotopes of interest. Results are summarized in Table XIII. No anomalous data was observed in well waters for this report period.

O 8.4 Surface Water Surface water samples were collected from three locations on a monthly basis. For the first quarter, the surface water samples were daily grab samples composited over the month due to the malfunction of the composite water sampler. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, 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 0.5 pCi/l to 7.812.4 pCi/l and 4.910.6 pCi/l to 11.710.8 pCi/1, respectively. The positive Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40. N. / Tritium was detected in the three surface water samples collected from location CA-SWA-sol during the first quarter 1985. Tritium activity in all three samples i was from a low of 1061 1 636 to a high of 9,525 1 725. The January and February samples were verified by reanalysis. An investigation into the cause of the tritium activity in the upstream sample pint (CA-SWA-SOI) has concluded that these samples must have been cross contaminated during collection. The problem was corrected in April and has not recured. No Tritium activity was detected in the first quarter surface water samples from collection locations CA-SWA-502 and CA-SWA-S03. ? Results of Strontium-90 and Strontium-89 analyses were all below the respective detection limits of 0.5 pCi/1 and 1.0 pCi/1. l Gamma Spectral analysis of surface water samples showed no detectable activity from isotopes of interest.

l l 8.5 Sediment h Washload, Bedload and Bottom Sediment samples were collected monthly from three locations along the Missouri River. Due to adverse weather conditions during January, no sediment samples were collected from locations CA-AQS-A and CA-AQS-C. 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 Gross Beta Range Range Sample Type pCi/g pCi/g g Washload 3.2 - 14.8 1.7 - 19,3 Bedload 1.5 - 2.7 0.6 - 1.6 Bottom 1.8 - 4.1 0.6 - 1.1 The highest activities of Gross Alpha and Gross Beta were seen in the Washload sediments at sample location D. All Washload Sediment samples collected during the first quarter of 1985 did not demonstrate detectable levels of Strontium-89 or Strontium-90. As may be seen in Table XVII no Gamma-emitting isotopes of interest were detected in any
, Washload Sediments collected during the first quarter.
The Bedload Sediment samples collected during this quarter did not show any detectable levels of Strontium-89 or Strontium-90. l t O No Bedload Sediments demonstrated any Gamma-emitting isotopes of interest. No Strontium-89 or Strontium-90 activity was detected in any of the Bottom Sediments collected during the first quarter of 1985. Gamma Spectral analysis demonstrated Cesium-137 activity in four of the seven Bottom Sediment samples collected during this quarter. (See Table XXI.) 1

8.6 Fish h Due to adverse weather conditions, no fish samples were collected from locations CA-AQF-A and CA-AQF-C during January. In addition, due to the paucity of fish, only four samples were collected from location CA-AQF-C during February. Five species of fish were collected monthly from each of the three collection locations in all other cases. Types of fish collected during this report period were: freshwater drum, bigmouth buffalo, smallmouth buffalo, carp, goldeye, river carpsucker, highfin carpsucker, shorthead redhorse, shortnose gar, quillback, white bass, gizzard shad, channel catfish, and blue catfish. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on all types of fish collected each month. Results are presented in Tables XXII thru XXVII. One g first quarter fish (channel catfish CA-AQF-D, collected 03/15/85) was lost in a laboratory accident and analytical results could not be obtained for this sample. However, no anomolous results were observed in any of the other fish samples collected from this location during March. Gross Alpha level for all samples ranged between the detection limit of 0.3 pCi/g to 1.1 1 0.3 pCi/g. Gross Beta activities ranged from a low of 1.9 1 0.1 pCi/g to a high of 6.4 1 0.2 pCi/g (sample CA-AQF-D, quillback, collected 03/15/85). Gross Beta activities seen in fish samples could be attributed to naturally occurring isotopes (e.g. Potassium-40). Strontium-90 analyses results were generally below the detection limit of 0.02 pCi/g. Two fish collected in the first quarter exhibited Strontium-90 activities.
$ 1 The Strontium-90 activity in the fish was not related to the operation of the l

i Callaway Plant, - since there has been no Strontium-90 detected in plant effluents. Strontium-90 activities ranged from non-detectable to 0.48 1 0.21 pCi/g (CA-AQF-A, freshwater drum, collected 3/19/S5). All fish data for Strontium-89 were below the detection limit of 0.05 pC1/g. Results of Gamma Spectral Analysis may be found in Tables XXIII, XXV, and XVII. One fish (river carpsucker, collected 03/19/35 at location C) exhibited a level of 0.109 1 0.032 Cs-137 activity. In addition, one other~ fish sample demonstrated a Cs-137 activity of 0.160 2 0.040 pCi/gm (freshwater drum, collected 03/15/85 at location D). l l l 1 O

8.7 Milk h Milk samples were cellected from two locations, the Green Farm and the Schnider Farm. The Green Farm supplied cow's milk while the Schnider 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 XXIX and XXX present results of these analyses. Iodine-131 was not detected in any of the milk samples collected during this period. Strontium-89 and Strontium-90 were not detected in any of the first quarter 1985 milk samples.

Isotopic Detection Limits and Activity Determinations O Making a reasonable estimate of the limits of 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. I
Background
Gross
/ ~
if a sufficient number of replicate analyses are run, it is to be expected that the results would fail in a 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 2 one 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 deviationi one or two Poisson standard deviations. The reported values are then considered to give 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 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
- 2. Counting Efficiency The fundamental quantity 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 l Any counter will show a certain counting rate without a sample in position.
i This background counting rate comes from several sources: 1) natural 1 environmental radiation from the surroundings, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background 1 counting rate will depend on the amounts of these types of radiation and the sensitivity of the counter to the radiation.
- 4. Background and Sample Counting Time 1
The amount of time devoted to the counting of the background depends on the level of activity being measured. In general, with low level samples, 9 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 the 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 , O fer="i = _ _s C+B A= C-B 1.96 3 (2.22)(V)(T) (R)(E)(e- At) (2.22)(V)(R)(E)(e- A t) WHERE: A= Activity as pCi per unit sample mass or volume. C= Sample counts. l B= Background counts. V= Sample volume or mass analyzed. i E= Counter efficiency in epm /dpm. 2.22 = Numerical constant to convert disintegrations per minute to picocuries. (e - At) = Decay factor to correct the activity to time of co!!ection. T= Counting time in minutes for sample and background. 1.96 = Statistical constant for the 95% confidence level. I O R= Chemical recovery or photon yield.
CEP uses the following method to determine lower limit of detection (LLD) as per NRC O 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 c.; stem background) that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation , represents a "real" signal. ! I For a particular measurement system (which may include radiochemical separation): LLD = 4.66 sb E V 2.22 Y exp ( Aa t) WHERE: l LLD is the "a priori" lower limit of detection as defined above (as pCi per unit mass or volume). I sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute). E is the counting efficieny (as counts per disintegration). V is the sample size (in units of mass or volume). 2.22 is the number of disintegrations per minute per picoeurie. Y is the fractional radiochemical yield (when applicable). ) A is the radioactive decay constant for t.he particular radioisotope. At is the 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 counting rate, or, of the counting rate of the blank sample, (as appropriate), rather than on an unverified theoretically predicated variance.

O b i Abstract 4 Controls for Environmental Pollution, Inc (CEP; has conducted a pre-operational radiological i monitoring program for Union Electric Company (UEC), Callaway Plant, Unit 1, since May i 5,1983. This quarterly report presents data for the months of April, May, and June,1985. Evaluation of pre-operational background radiation levels in the environs around Union Electric Company's Callaway, Plant Unit 1, entailed sampling at strategic points in various exposure pathways. The following types of samples were collected and analyzed: ~ milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, shoreline sediment, fish, airborne particulates, airborne radioiodine and direct i radiation (TLD). 4 O 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. i l l e l O l l i
1.0 Introduction h This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the second quarter of 1985 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 radiological impact on the environment caused by the operation of the Callaway Plant.
h 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 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 l Missouri River in Callaway County, Missouri. The plant consists of a 1150 MWE l pressurized water reactor, which achieved initial criticality on October 2,1984. O1 l O 2.0 Description of the Monitor.ng 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. A summary of the Callaway Plant Monitoring program is contained in the first quarter report 1985 (page 3). No changes in the monitoring program occured during this quarter. O f f i i

7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter Report 1985 (page 28). 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 h previous data are considered out of baseline range or anomalous. 8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from March 28, 1985 thru June 27, 1985. Nine of the airborne particulate stations were also collection sites for airborne radiciodine (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. The range of Gross Beta activity at each of the sampling locations follows. Measurements are in terms of pCi/m3 . h

(v 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 1 and 2 J 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. s The May,1985 TLD's for Stations 09,13, and 14 were inadvertently left in the field when all other May TLD's were collected. The annual TLD's for those locations were collected instead. Stations 09,13, and 14 for May were then collected with the June TLD's. Replacement annual TLD's for those three stations were replaced on 05/29/85. O Data appearing in Tables IX thru XI are the result of reading and averaging the i 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. t Exposure levels for all monitoring locations are consistent with background les o< detected during the preoperational monitoring program. No anomalous TLD data was seen during the secend quarter of 1985. L-TABLEIX THERMOLUMINESCENT DOSIMETRY APRIL 1985 h 03/27/85 - 05/01/85 Total Exposure Station Exposure Rate

8.3 Well Water h 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 Xil presents the results of the radiochemical analyses. Gross Alpha activity ranged from non-detectable levels to 5.012.4 pCi/1. Gross Beta levels varied from less than 3.0 pCi/l to 18.812.3 pCi/1. The Gross Alpha and Gross Beta levels were consistant with the preoperational data. Results of Tritium and Strontium-89 were below the detection limits of 500 pCi/l and 1.0 pCi/l respectively for all samples. O Gamma spectrometry showed no detectable levels of isotopes of interest. Results are summarized in Table XIII. The three well water samples collected during June exhibited Strontium-90 activity. CA-WWA-D01 had a Strontium-90 activity of 1.0 10.7 pCi/1, CA-WWA-F05 had a Strontium-90 activity of 2.0 10.7 pCi/1, and CA-WWA-F15 had a Strontium-90 activity of 1.810.7 pCi/1.

t 8.4 Surface Water Surface water samples.were collected from three locations on a monthly basis.
- For the second quarter, the surface water samples were daily grab samples composited over the month due to the malfunction of the composite water samplers. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, 2
Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are a summarized in Tables XIV and XV. t Cross Alpha and Gross Beta anal;ses of surface water samples showed a range of activities of less than 2.0 pCi/l to 7.92.1 1 pCi/l and 2.30.5 1 pC1/1 to 22.231.0pCi/1, respectively. The positive Gross Alpha and Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40, and O ere coesis1eet e the greegeretiomei eete. All Tritium data from surface water samples were below the detection limit of 500 pCl/l. Strontium-90 was detected in two of the surface water samples collected during the second quarter of 1985 (CA-SWA-501 and CA-SWA-502 collected 06/04/85). No Strontium-39 was detected in any of the Surface Water samples collected this quarter. 1 l i j Gamma Spectral analysis of surface water samples showed no detectable activity from isotopes of interest.

l 8.6 Fish h Fish were collected from three locations on a monthly basis. Types of fish collected during this report period were: white bass, freshwater drum, shortnose gar, shorthead redhorse, bigmouth buffalo, carp, goldeye, river carpsucker, blue catfish, white crappie, largemouth bass, gizzard shad and channel catfish. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on all types of fish collected each month. Results are presented in Tables XXil thru X X Vil. The activity levels are consistant with the preoperational data. Gross Alpha levels for all samples ranged between the detection limit of 0.3 pCi/g to 0.40.2 1 pCi/g (sample CA-AQF-A, River Carpsucker, collected 04/02/S5). Gross Beta activities ranged from a low of 3.81 0.1 pCi/g to a high of h 8.310.1 pCi/g (sample CA-AQF-A, Carp, collected 06/24/85). 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 0.02 pCi/g. All fish data for Strontium-89 were below the detection limit of 0.05 pCi/g. Results of Gamma Spectral Analysis may be found in Tables XX111, XXV, and XXVII. Three fish exhibited levels of gamma-emitting nuclides of interest slightly above the deter table levels.

3.8 Vegetation h Vegetation samples were collected from four sampling locations during the second quarter of 1985. Vegetation samples consisted of Turnip Greens, Mustard Greens, Spinach, Lettuce and Cabbage collected from the Zimmer, Becker, Hazlett and Meehan Farms. All vegetation samples were analyzed for Goss Alpha, Gross Beta, Iodine-131, and by Gamma Spectrometry. Results are presented in Tables XXX and XXXI. Gross Alpha activities in the vegetation samples collected this quarter ranged from less than 0.3 pCi/g to 0.610.2 pCi/g. These Gross Alpha activities are consistent with the levels found in the preoperational monitoring. Gross Beta levels observed in the vegetation samples ranged from less than h 4.610.1 pCi/g to 29.510.3 pCi/g, These Gross Beta activities are consistent with levels of naturally occurring isotopes commonly found in vegetation during the preoperational monitoring. No gamma-emitting isotopes of interest were detected in any of the vegetation samples. Iodine-131 was detected in the Mustard Greens sample collected at the Meehan Farm on 05/29/85 (CA-FPL-V7). The source of the lodine-131 activity in this sample cannot be determined. This was an isolated occurrence. Other vegetation samples collected at the Meehan Farm on 05/29/85 did not show an Iodine-131 concentration and Mustard Greens collected on 06/17/35 had no detectable I-131 activity. h TABLE XXX VEGETATION Sample Identification; Sample Radiochemical Analysis pCi/st Date Collected Location Gross Alpha Gross Beta lodine-131 CA-FPL-V3 05/29/85 Lettuce Hazlett Farm 0.50.1 1 22.210.3 < 0.03 CA-FPL-V3 05/29/85 Spinach Hazlett Farm 0.30.1 29.510.3 < 0.03 1 CA-FPL-V3 05/29/85 Turnip Greens Hazlett Farm 0.30.1 15.810.2 < 0.03 1 C A-F PL-V2 06/17/85 Mustard Greens Hazlett Farm < 0.3 5.90.2 < 0.03 1 CA-FPL-V3 0 06/17/85 Spinach Hazlett Farm < 0.3 9.90.2 1 < 0.03 C A-F PL-V3 06/17/85 Turnip Greens Hazlett Farm < 0.3 11.410.2 < 0.03 CA-FPL-V3 l 06/17/85 !

O Abstract Controls for Environmental Pollution, Inc (CEP) has conducted a pre-operational radiological monitoring program for Union Electric Company (UEC), Callaway Plant, Unit 1, since i May 5,1983. This quarterly report presents data for the months of July, August, and September,1985. Evaluation of pre-operational background radiation levels in the environs around Union Electric Company's Callaway, Plant Unit 1, entailed sampling at strategic points in various exposure pathways. The following types of samples were collected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, shoreline sediment, fish, airborne particulates, airborne radioiodine and direct radiation (TLD). 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 h This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during the third quarter of 1985 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. h 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 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 scurces 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 2,1984. O l d i
. 2.0 Description of the Monitoring Program Union Electric Company has contracted with Controis 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 preagram is contained in the first quarter report 1985 (page 3). No changes in the monitoring program occured during the' third quarter,1985. i ) O i i h i i 4 I i O e nn-----,,-v------, .,,,c,,-,-,-w rw. m,...,nn..-e-. . . ~ , . - n,v..-.- n ~,, n n c-n , r,..n,-,,--,.,nnnm,. .- a ,--nne,e -.,n e n, n. w n . nm n, ,--

No changes in the Quality Control Program occurred 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 h previous data are considered out of baseline range or anomalous. 8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from June 27, 1985 through October 3, 1985. Nine of the 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. The range of Gross Beta activity at each of the sampling locations follows. Oi l

Mean Gross Beta activities at the other sites varied from 0.012 3 0 006 pCi/m3 at Site Site B3, to l 0.025 3 003 0 pCi/m3 at Site B6. . Mean weekly Gross Beta activities ranged from a low of 0.015 3 0.007 pCi/m3 during the collection period of 08/29/85-09/05/85 to a high of 0.026 3 0.006 pCi/m3 during the collection period of 07/18/85-07/25/85. 1

All results of the airborne particulate composite analyses for Strontium-39 and O Strontium-90 were below the detection limit of 0.005 pCi/m3 and 0.002 pCi/m3 respectively. Gamma spectral analysis of the Site composites showed the following activities: Collection Location isotope Identified pCi/m3 Site A-1 Beryllium-7 0.012 3 0.001 Site A-5 Beryllium-7 0.010 3 0001 Site A-9 Beryllium-7 0.012 3 0.001 Site B-1 Beryllium-7 0.011 3 0.001 Site B-6 Beryllium-7 0.0133 0.001 Site B-8 Beryllium-7 0.015 3 0001 Results of the airborne radioiodine analyses may be found in Table Vill. No samples exhibited levels of lodine-131 greater than the detection limit of 0.005 pCi/m3 The levels and fluctuations of radioactivity detected in the air particulate and radioiodine samples collected during the quarter were consistent with the previously accumulated preoperational data. w O 1

8.2 Thermoluminescent Dosimetry Thermoluminscent Dosimetry (TLD) was employed to determine direct radiation levels in and around the Callaway Site. Celcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas 1 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 are consistent with background g levels detected during the preoperational monitoring program. No anomalous TLD data was seen during the third quarter of 1985. O l

I 8.4 Surface Water Surface water samples were collected from three locations on a monthly basis. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-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/l to 10.533.4 pCi/l and less than 2.0 pCi/l to 2!.432.3 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 h 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.

8.6 Fish h Fish were collected from three locations on a monthly basis. Types of fish collected during this quarter were: black buffalo, freshwater drum, shortnose gar, flathead catfish, bigmouth buffalo, carp, river carpsucker, blue catfish, blue sucker, gizzard shad and channel catfish. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectral analysis were performed on ai! types of fish collected each month. Results are presented in Tables XXil thru XXVII. The activity levels are consistent with the preoperational data. Gross Alpha levels for all samples were below the detection limit of 0.3 pCi/g. Gross Beta activities ranged from a low of 1.53 0.1 pCi/g to a high of 8.630.2 pCi/g (sample CA-AQF-D, River Carpsucker, collected 07/25/85). Gross Alpha and Gross Beta activities seen in fish samples could be attributed to naturally h occurring isotopes (e.g. Potassium-40). Strontium-90 analyses results were below the detection limit of 0.02 pCi/g. All fish data for Strontium-89 were below the detection limit of 0.05 pCi/g. Results of Gamma Spectral Analysis may be found in Tables XX111, XXV, and XXVil. One fish exhibited levels of gamma-emitting nuclides of interest slightly ab'ove the detectable levels.

I l l 8.8 Vegetation O' Vegetation samples were collected from four sampling locations during the third quarter of 1985. Vegetation samples consisted of Turnip Greens, Mustard Greens, Spinach, Lettuce and Cabbage collected from the Zimmer, ' Becker, Hazlett 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 activities in the vegetation samples collected this quarter ranged from less than 0.3 pCi/g to 0.420.2 pCi/g. These Gross Alpha activities are consistent with the levels found in the preoperational monitoring. Gross Beta levels observed in the vegetation samples ranged from 4.030.1 pCi/g h to 25.620.3 pCi/g. These Gross Beta activities are consistent with levels of naturally occurring isotopes commonly found in vegetation during the preoperational monitoring. No gamma-emitting isotopes of interest were detected in any of the vegetation samples.

O 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 October, November, and December, 1985.
- Evaluation of radiation levels in the environs around Union Electric Company's Callaway, Plant Unit 1, entailed sampling at strategic points in various exposure pathways. The J
following types of samples were collected and analyzed: milk, vegetation, surface water, ) well water, bottom sediment, bedload sediment, washload sediment, shoreline sediment, fish, airborne particulates, airborne radioiodine, direct radiation (TLD) and soil.
;O 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. t l l l l ?____-__________
1.0 Introduction h This report presents an analysis of the results of the Radiological Environmental Monitor:ng Program conducted during the fourth quarter of 1985 for Union Electric Company, Callaway Plant, Unit 1. In cornphance 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. g 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 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 2,1984. O i 4 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. .
l A summary of the Callaway Plant Monitoring program is contained in the first quarter report 1985 (page 3). No changes in the monitoring program occured during the fourth 4 quarter,1985. h

3.0 Analytical Procedures The analytical procedures routinely used by CEP to analyze samples are discussed in the First Quarter 1985 Report (pages 15 to 20). 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 1985 Report (pages 20 to 21). No new sample preparation methods were used this quarter. 5.0 Major Instrumentation Major analytical intrumentation used by CEP are discussed in the First Quarter 1985 Report (pages 21-23). No new instrumentation was used for samples collected this quarter. g 6.0 Isotopic Detection Limits and Activity Determinations A discussion of the calculations used in determining detection limits and activity by Controls for Environmental Pollution, Inc., is found in Appendix B, First Quarter Report 1985. Table III in the First Quarter Report 1985 gives the detection limits for radiccht.mical and chemical analytical methods. For each sample type, the table lists t'.e detection level for each isotope analyzed. Table IV in the First Quarter Report 1985 gives the detection lim!ts for gamma spectrometry. The table lists isotopes and respective detection levels for air particulate, airborne radiciodine, vegetation, soil and fish. g 1 1 i 4 -O The sample counting times and the aliquot size used for detection limit calculations j 'L and actual analyses are shown in the First Quarter Report 1985, Tables V and VI, , . respectively. . i 4 3 4 i I f j , i \O l l 4 I l i > 1 i a i j i l i I I 1 O . $ e I
7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter Report 1985 (page 28). No changes in the Quality Control Program occurred 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 g previous data are considered out of baseline range or anomalous. 8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from October 3,1985 through January 2, 1986. Nine of the airborne particulate stations were also collection sites for airborne radiciodine (See Table Vill). All of the air particulate samples were analyzed for Gross Beta activity. Gamma Spectrorr stry, Strontium-90 and Strontium-89 analyses were performed on quarterly composites from each station. The range of Gross Beta activity at each of the sampling locations follows. O 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 1 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 locationc 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 are consistent with background g levels detected during the preoperational monitoring program. No anomalous TLD data was seen during the fourth quarter of 1985. O TABLE IX THERMOLUMINESCENT DOSIMETRY OCTOBER,1985 09/27/85 - 10/30/85 Total Exposure Station Exposure Rate

8.7 Milk h 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 XXVII and XXIX present results of these analyses. Iodine-131 was not detected in any of the milk samples during this pericd. All 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 S trontium-90. O No gamma-emitting isotopes of interest were detected in any of the milk samples. The above results are consistent with the previously accumulated preoperational data.

O 8.8 Venetation Vegetation samples were collected from three sampling locations during the fourth quarter of 1985. Vegetation samples consisted of Turnip Greens, Mustard Greens, Lettuce and Cabbage collected from the Becker, Hazlett, 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 activities in the vegetation samples collected this quarter were all , less than 0.3 pCi/g. These Gross Alpha activities are consistent with the levels found in the preoperational monitoring.
~
Gross Beta levels observed in the vegetation samples ranged from less than 0.1 pCi/g to 15.910.2 pCi/g. These Gross Beta activities are consistent with levels of naturally occurring isotopes commonly found in vegetation during the preoperational monitoring.

y.7.,. , t INTRODUCTION Purpose Union Electric Company (UE), in response"to Nuclear Regulatory; Commis-sion (NRC) mandate, has undertaken a program to monitor the potential impacts of cooling tower drif t on the local flora surrounding the UE Callavay plant in Callaway County, Missouri. The goals of the program are to establish, a data-base of existing vegetation conditions at the Callaway ' Plant site using color infrared aerial photography, to document any 'n' a turally occurring vegetation stress, and to determine if any vegeta' tion damage can be attributed to opera- .l' , 1r tion of the cooling tower. Interpretation of aerial photographs has been used - to prepare this information. This has been supplemented by ground truthing to ensure accurate interpretation of photographs and field phytopathological as-to identify the causes of any vegetation stress encountered. This () sessment present work complements other vegetation monitoring undertaken at the study l site. Work performed in 1973-1975, 1981, and 1983-1984 concentrated on a set of permanent terrestrial study plots and used classical botanical techniques to describe the vegetation community at the Callaway plant. 4 EXECUTIVE
SUMMARY
h t Baseline environmental information En the condition of vegetation at e the Callaway plant site has been developed ~ through infrared aerial photogra-phy, photointerpretation and ground truthing of stressed vegetation, vegeta-tion mapping and phytopathological diagnosis of stressed vegetation during
/
August, 1985. . d t
-k..- ,
't' Ten terrestrial study plots were photographed with infrared film at a scale of 1" = 250'. Residual lands were photograpbed at a scale of 1" =
1000'. Photointerpretation was performed based upon the dif ferential inf ra reil reflectance characteristics of healthy versus stressed tree cover. The in-i- f rared photographic record was then verified with a ground truthing field
, inspection. On-site and laboratory phytopathological diagnoses were made for stressed vegetation identified from aerial photography. A vegetation map was ,
produced which showed the location of stressed vegetation, i No evidence of effects of drift from the cooling tower was found. The increase incidence of foliar diseases that were found can be attributed to
< higher precipitation during 1985. No distributional pattern of these diseases
- ^
was identified during the study. Therefore, the foliar disease found in the 4
> Callaway vegetation during 1985 can be directly attributed to natural causes
(} and not operation of the ecoling tower. d' w a l. v i s

r STUDY METHODS O Uninn Electric's Environmental Service Department has coordinated in-
- frared aerial photography, photointerpretation and ground truthing of st ressed vegetation, vegetation mapping and phytopathological as'sessment of stressed vegetation for the Callaway Plant site.
Aerial Photography Aerial photography for this project was flown from 0930 to 1015 hours on August 12, 1985 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 photo-graphed with 60 percent forward overlap at a scale of 1" = 250'. The residual l () 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 brightness which may occur along the edges of an aerial photographic exposure. Duplicate sets of positive film transparencies and positive prints were produced in 9" by 9" format. Photointerpretation Analysis of color infrared aerial photographs for the presence of vegetation stress is based upon the changes in infrared foliage reflectance that occur as a result of plant stress. A number of technical sources describe the theory and applicatien of color infrared vegetation analysis and were used as a guide for the photointerpretation in this study. Plants under
-- . ~-= . _ .
stress due to insec t attack, disease or environmental conditions such as ([) drought exhibit discoloration of their foliage on color inf rared film because of loss of reflectance. This decrease of infrared reflectance occurs when normally highly reflective spongy leaf mesophyll cells collapse because of plant stress (Colwell, 1956). Vegetation color differences can he used to make inferences about plant vigor (!?urtha, 1982; Barrett and Curtis, 1976), licalthy deciduous trees are highly reflective of inf rared radiation and appear as red and magenta in color inf rared photographs. Evergreen pines and cedars at the site appear in shade of reddish gray. Stressed vegetation with leaf yellowing apparent in normal spectral color photography, appears in shades of emuve, blue-grey, yellow and white in color infrared photography. then vegetation is dead and dry it reflects as yellow and tan on color infrared photography. 4 () Using these differential reflectances as signature guides, examination of photographs was performed with simple magnification. Trees which were possibly in stressed condition were marked on photographic prints for subse-quent ground truthing. Ground Truthing i Ground truthing of stressed -vegetation was a process of locating (with . the aid of aerial photographs and topographical maps) potentially stressed trees recorded on-aerial photograph prints. The condition of these trees and the assessment made during phytopathological investigations wers then cor-related with the infrared photographic signature in order to identify stressed trees. Ground truthing took place on August 27 and 28, 1985.

After photointerpretation and ground t ru t h in g , the locations of stressed or dying trees were plotted on a map of the Callaway Plant site at a scale of 1" = 2000' (Figure 1). In areas of isolated tree damage individual stressed or dying trees were represented by an asterisk (*) on the vegetation
- map. Areas with relatively high densities of stressed or dying trees were re-presented as shaded damage zones on the vegetation map. A considerable number of these trees that were plotted on the site vegetation map were inspected during ground truthing for later phytopathological appraisal.
Phytopatholoeical Investigations Individual trees that were located at the Callaway site from aerial photograph plotting were appraised by plant pathologist Barbara S. Lucas of () Columbia, Missouri. The purpose of this appraisal was to provide diagnoses of the causes of vegetative stress found on specimens at the study site. The causes of plant stress were to be separated into three major categories:
- 1) environmental, 2) disease, and 3) insect. Plant species vary in their tol-erance 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 -entioned above.

Freezing and thawing, drought, flooding, lightning daeace, chemical in-O jury, mechanical injury, or high winds are all examples of environmental con-ditions that can result in stressed plants. These conditions may cause outright death of plants or may stress them to a point where they are unable to withstand invasion by secondary disease organisms or insect pests. Disease is a condition in plants brought about as a result of invasion of plant tissues by other living microorganisms. Primary diseases, such as Oak wilt and Dutch Elm disease (DED), are caused by microorganisms that can inrade healthy plant tissues. These organisms consume plant-supplied water l l and nutrient reserves for their own growth, thereby creating a stress on the plant. Secondary diseases, such as !!aple decline, are caused by ' disease complexes' which usually occur on plants which have already been stressed f, rom other causes. Disease complexes are generally caused'by microorganisms which by themselves cannot invade tissues of healthy plants. When plants are stressed, however, their normal resistance to invasion-by insect and disease organisms is lowered. The disease-complex organisms then are able to invade plant tissues causing further stress and/or death of the plant. Insects may cause direct or indirect damage to plants which may result in stress. Direct damage usually is a result of feeding on_ plant parts such as leaves, bark (cambial layers), wood, or roots. Oviposition (egg-laying) is another type of direct damage which can restrict the flow of water er nu-trients in the plant. Insects may also cause indirect damage by serving as vectors of disease-causing organisms; insects feeding on diseased plants inad-vertently carry spores of disease organisms to healthy plants.

The elements that were analyzed during diagnosis of stressed tree ()
\^
specimens were: history of forest managemen t practices or herbicide applica-tion, site edaphic conditions, condition of surrounding vegetation, recent meteorological record, and inspection of tree leaves, branches, bark and roots. In addition to field observations, standard culturing procedures using twigs and small branches were carried out in the laboratory in 1984 in an at-tempt 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 inconclu-sive in 1984 and were not repeated in 1985.

REST'LTS AND DIStTSS f('N V Photointerpretation and Ground Truthing Analysis of color infrared aerial photographs indicated that the vast najority of deciduous trees at the Callaway Plant site were in good health as indicated by their intense magenta reflectance. Certain deciduous trees ob-served across the study site displayed somewhat lighter magenta or pink coloration or a light fringed appearance on inf rared aerial photographs. Ground truthing revealed these trees to be species such as sycamore (Platanus occidentalis), persimmon (Diospyros virginiana) and mulherry (Morus rubra) which were in good health. Such trees possess a somewhat different in f rared color signature than the deep magenta of the oaks and hickories which are dom-inant at the Callaway site. Deciduous trees that showed signs of stress re-

photography. These deciduous trees were plotted as individual stressed or dy-ing trees on the site vegetation map (Figure 1). The distribution of these trees showed no apparent pattern. Ground truthing and phytopathological exa-cination revealed that a variety of stress factors (detailed below) were af-fecting these trees. In the southern portion of the study site several areas with relatively high densities of stressed or dying deciduous trees were ob-served on the aerial photographs. These trees displayed yellowish tan in-frared reflectance and were recorded as tree damage zones on the site vegeta-tion map. Field inspection revealed that these zones were subject to forest management practices carried out by the Missouri Department of Conservation in which less robust tree specimens or undesired species were girdled by chain 4 saw cutting. The culled dead and dying trees appeared as stressed aggrega-
,_s tions on infrared aerial photography.
Healtny eastern redcedar (Juniperus virginiana) and plantation grown
] white pine (Pinus strobus), both evergreen species, displayed reddish pray coloration in infrared photography. The stand of white pine was in fairly good condition but with some lower branch dieback, perhaps due to crowding and sunlight shading. Across the study site eastern redcedars were in good condi-tion with the only apparent damage being scattered broken branches caused by-winter icing.
Phytopatholcgical Investigations Oak wilt, a vascular disease caused by the fungus Ceratoevstis fagacearum was diagnosed as the cause of stress in oak specimens. These trees were either red oak (Quercus rubra), black oak (Ouercus velutina), or white oak (Guercus alba). Diagnoses were based on symptom e3:pression in the field. Symptc.n development begins in the upper crown of infected trees. Leaves ex-O hibit marginal scorching, a moisture stress symptom, and often fall from the tree. Leaf scorch symptoms develop because the fungus multiplies in the vascular system, effectively blocking the uptake of water. The disease develops rapidly in the red oak group, spreading throughout the entire tree. Infected trees in this group are of ten killed in a single season. Disease development in white oaks is much slower. Symp*.om expression is usually con-4 filed to a few branches each year. Q:ite oaks decline over a period of sev-eral years. A black discoloration of the cuter sapwood, indicative of a vascular disease, was observed in the infected white oaks. Although the oak wilt fungus was not recovered in culture, it is believed that this fungus is the cause of mortality in many of the oaks that were examined. Low percentage recovery of C. f acacearum from oak
I m wilt-infected trees has been associated with high summer temperatures and low rainfall (Bretz and Morison, 1953; flouston et al., 19M; Tainter and Cubler, 1973). Once a tree dies, the fungus produces mycelial mats underneath the ou-ter bark. The mycelial mats, or ' pressure pads', of ten split the hark, expos-ing the pad surface upon which spores are produced. The spores have a fruity odor which 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 Cubler, 1973). Inva-sion of the oak-wilted trees by secondary disease organisms inhibits pad formation (Tainter and Gubler, 1973; Shigo, 1958). Dutch Elm disease (DED), caused by the fungus Ceratoevstis ulmi, was O ' identified as the stress factor on slippery elm (Ulmus rubra) trees. Diag-noses were based on visual symptors: wilting, die-back of branches, anc discoloration of the vascular system. DED is a vascular disease similar to oak wilt. It has been devastating on American elm (Uleus americana) and other native species because it is caused by an ' introduced' pathogen against which our native elms have not developed genetic resistance. The third disease that was encountered was root and butt rot. Root and-butt rot was observed on plantation grown white pine (Pinus strobus), walnut (Juglans nigra) and maple (Acer saccharum). Root and butt rots are caused by a variety 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 survive as saprophytes in cut stumps. ~ hey utilize the stuep as an energy O source for growth throneb the soil unt i l a hea l thy roo t - te .encoun tered . P ese rots are the re fo re c ornnon in logged areas. Above-ground symptons of root and i butt rot are expressed as branch die-back and sparse, off-color foliage. Fruiting bodies (Hasidiocarps) 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. Other than oak wilt, the most frequently encountered.cause of stress. i was mechanical injury and its after effects. Some mechanical wounds, such as i frost cracks and broken branch stubs, are the first step in a discoloration i and decay (heartrot) process. Although a succession of microorganisms are ia-i volved in the decay process, heartrot begins with a wound. Heartrot lowers the tree's value as harvestable timber,.but the tree itself may survive for
! () years. The heartwood which becomes rotted is not involved in the transport of-water and nutrients essential to the tree. Trees.affected by heartrot are structurally unsound and subject to - repeated injury from winds, snow and ice 4 accumulation, etc.
i I
- Other wounds, such as lightning strike that~ recoves a. layer or patches i
l of bark along the length of the trunk, reduce the . amount of- water and nutrient i l translocating tissue available to meet the needs of the tree. In addition, a direct lightning strike usually damages the root systen substantially. When the balance between roots and the shoots is ; destroyed, decline of thel crown-
- begins.

t ter springs and %unmer% wlen compared to Vi-vea r averares (see Tah!c !). These condittons are eenerally not favorable for rapid and healthy plant development. Injurv to plants by hot or cold temperature ext remes may be by direct or indirect effects on plant tissues. Direct injury usually consists i of some type of mechanical damage to cells and/or cell components. T.xanpl es
- of this type of injury are: 1) intracellular ice crystal formation that can.
result in disruption of cell membranes, or 2) intercellular ice crystal forma-tion which, through greater negative water potentials of ice crystal surfaces, draws water out of cells, thus dehydrating protoplasm. Dehydration induces disorganizing effects in the protoplasm. Also, protoplasmic distortion from the too rapid re-entry of wster into dehydrated cells from alternate - freezing and thawing of tissues may occur with freezing night temperatures and warmer, 4 sunny days. Indirect injury caused by temperature extremes is generally related to metabolic disorders. In temperate regions the effects of high temperature are more commonly observed than injury from low temperatures. High daily tempera-
' tures (above the maximum temperature for growth of a given species) coupled f
with high night temperatures adversely af fect plant growth _ and development in two ways: 1) by decreasing total net photosynthate production per hour, and
~
- 2) by increasing total r.et respiration per 24 hours. The result.of such a situation is a net decrease in overall plant sustenance and an increasing debilitation of plant health. The extremely hot summer teeperatures that were experienced in 1981 were not repeated in 1985 l

With the ample precipitation which occurred _ in the springs ' of.1983, 1 1984, and 1985, these soils absorbed large quantities of water and because of their low permeability rates, became 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 physical damage, resulting in wilting or chlorosis. Additionally, restricted root growth can result in an accumulation of toxic metabolites which interfere with defense reactions of the host plant (Schoeneweiss, 1975).

Several tree species located on the edge of a woods adjacemtn to a road were showing stress symptoms. The foliage of black cherry was very sparse, with leaves remaining only on the tips of branches. Nearby. hackberry and oaks also had thinning crowns. Two persimmons were diagnosed as having anthracnose. Anthracnose is the general name for a foliar disease caused by a distinct group of fungi. Characteristic symptoms of - this foliar disease are large, irregular lesions. Site #2 This site is primarily a red and black oak stand- in a timber management area. !!any trees have been girdled and lef t standing. Adjacent, non-girdled trees are exhibiting dieback and decline synptoms, including scattered brach dieback and thinned crowns. Dieback and decline begin when a tree's root sys-te: is no lenger extensive enough to support the needs of the foliage. It is likely that the decline of red and black oaks en this site is due to a combi-I natien ef factors, including environmental stress, site disturbance, and root rot. Root rot is considered to be a contributing factor to the decline, because the dead standing trees provide an excellent food base'for1the root-rotting fungi. , O 4

Site #3 An old American elm that was recorded in 1984 as having pale foliage and stump sprouting was still alive in 1985. The tree continued to decline, however. Dieback kas now prominent in the crown. The tree has been growing on very shallow soil and many larger roots are visible on the soil surface. The tree appears to be dying a natural death of old age. An area of this site that was not visited in 1984 was inspected in 1985. A number of environmental and site-related problems were observed. Two trees, a black locust and a walnut with pale, sparse foliage and branch (%)) dieback were noted as being old lightning strikes. A scarlet oak growing on an eroded slope had a portion of its root system washed sway. A nearby chest-nut oak showed evidence of an old wound and basidiocarps of a wood rotting fungus at its base. Both oaks were located on a site heavily used by cattle. The soil was very compacted and there was very little understory vegetation. A cluster of oaks along a fence row appeared healthy, except for death of the lowest branches. It's likely that this death was due to the ef fects of shading. An old black cherry with severe heart rot is barely alive, but may not last much lenger. This tree is aleng a fenceline and next to a farmroad. These environmental stresses to the tree's roots, along with rajor physical ,f S dacage to the trunk and crown, have caused this tree's decline. \_) a
Site #4 A line of backberry was rev i s i t eif in 1985. 5bliare continue <l to be pale and sparse, with ind iviilual leaves smaller than normal. On closer exari-nation, it was noted that the leaves had a mosaic sympton (scattered islands
.of green and chlorotic tissue). This mosaic symptom, which is characteristic of virus infection, was not evident in 1984. Symptom expression was probably masked by the high temperatures in 1984.
An American elm that was in a state of decline in 1984 was revisited in 1985. This tree is very old and is growing on very shallow soil, as evidenced by exposed bedrock in the vicinity. This tree 's extremely shallow root system was clearly evident as many large roots emerged above ground around this tree. Several black locust and walnut trees in the vicinity of this site that O
\m ,/ showed overall decline had evidence of lightening scars. .
Sites #5 and #6 A large American elm with characteristic symptoms of Dutch elm disease was observed. A number of red and black oaks at these sites' continued to shou the symptous characteristic of oak wilt that were evident in 1984. Early crown defoliation and leaf scorching were present as well as crown thinning and scattered branch dieback. Also, an understory sugar maple with severe browning and scorching of the periphery of the leaves was observed. This problem was probably due to coisture stress.

A stand of red and black oaks on this site continued to exhibit the characteristic symptoms of oak wilt observed in 1984. Leaf scorch and early o defoliation of the crown were prominent.

CONCLUSIONS (')i
\.
The most obvious lifference between 1984 and 1985 observations was the greater incidence of foliar anthracnose and leaf spotting disesses in 1985. j These foliar diseases were evident on hickory and understory shrubs at 111 locations sampled. Foliar diseases are most severe during wet sessons. The meteorological information in Table 1 demonstrates that the summer months (June-Au g) 1985 were the fourth wettest on record at the Fulton station in the past 100 years. No distributional pattern of these diseases was identified during the study.
- No evidence of effects of drift from the cooling tower was noted. The increased incidence of foliar diseases can be attributed to higher precipita-tion in 1985. No d'istributional pattern of these diseases was identified dur-
) () ing the study. Most of the deciduous tree cover at the Callaway site is healthy and' reflects intense magenta on infrared aerial photography. Those specimens that are stressed or dying are recognizable on color infrared photography because of their mauvish pink, grey or tan reflectance. The. largest number of these stressed or dying trees occur in six tree damage cones in which a forest management program is carried out by the Missouri Department of Conservation. In these areas the less robust tree specimens were chain saw girdled for the purpose of selective stand thinning. 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 pines are apparent because of their tan infrared reflectance.
Oak wilt was t '.e natora' stress occurrine with t% bichest incidence, It is expected that oak wilt will continue to spread, both bv insect vectors and natural root grafts. The rate of development of this protier depends on environmental conditions. i.oc a l increase of oak wilt incidence is lower in southern regions where mean monthly summer temperatures are high (Tainter and Cubler, 1973). Climatic conditions f rom May 1983 through August 1985 consisted of cold winters, wetter springs and hotter, drier summers when compared to 30-year averages. Such conditions do not favor rapid and healthy plant development. Because of such meteorological conditions and local edaphic factors it is ex-pected that some mortality and decline due to moisture stress will be evident next spring.

1.0 INTRODUCTION
i In accordance with Appendix B, Seciton 5.4.1 of the Callaway Plant Operating License, the following report was prepared by Union Electric on all changes in plant design or operation, test.and experiments made in accordance with Section 3.1 of Appendix B which involved a potentially significant unreviewed environmental question. Thin report covers all plant modifications that were completed ' from January 1,1985, through December 31, 1985. 4 During 1985 there were three plant modifications that involved a potentially significant unreviewed environmental question. The interpretations and conclusions regarding this plant modification along with a description of the change are presented below. 2.0 ENVIRONMENTAL EVALUATIONS 2.1 Callaway Modification Package 84-02-18 2.1.1 Description of Change l This change involved the installation of a pump station ' and additional piping between the demineralizerAlso, the l O- neutralization tank and sludge lagoon No. 3. installation of discharge piping from Lagoon No. 3 to the- . plant discharge line. This change allows the separation l j of demineralizer regeneration waste from other sludge
.l 1
waste in which the water is reused. i 2.1.2 Evaluation of Change The installation of the pump station and additional piping ! did not result in a significant increase in any adverse environmen'tal impact, since all measurable nonradiological environmental effects are confined to the areas previously disturbed during site preparation and plant construction. Therefore, this change does not constitute an unreviewed e environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.- i 2.2 Callaway Modification Package 84-05-85 i, i 2.2.1 Description of Change This change involved leaving the Galion Crane, used during construction, on site. This crane will be used to lif t ' equipment up to the containment equipment hatch during
- plant outages.

O 2.2.2 Evaluation of Change The location of this crane is such that all measurable nonradiological environmental effects are confined to the areas previously disturbed during site preparation and plant construction. Therefore, this change does not constitute and unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License. 2.3 Callaway Modification Package 84-05-86 2.2.1 Description of Change This change involved the installation of two 100,000 gallon, above ground, stainless steel discharge monitor tanks next to the radwaste building. These discharge monitor tanks allow the batching of larger volume of waste for discharge to the river. 2.3.2 Evaluation of Change The construction of the two discharge monitor tanks did not result in a significant increase in any adverse O environmental impact, since all measurable nenradiological environmental effects are confined to the areas previously disturbed during site preparation and plant construction. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License. .O
