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 1984 and the' environmental evaluations for plant modifi-cations completed since issuance of the operating license. The:first section of this report summarizes and interprets the results of the radiological environmental monitoring program
. conducted in accordance with Technical Specification Section 3/4.12. Section 2 describes the nonradiological environmental program and its results conducted in accordance with Section-2.2 of Appendix B to the Callaway Plant Operating License. The third section of this report describes changes in plant design or operation, test, and experiments made in accordance with Section 3.l'of Appendix B to the Callaway Plant Operating License.
This Annual Environmental Operating Report is submitted in accordance with Section 6.9.1.6 of the Technical Specification and Appendix B to the Callaway Plant Operating License. CONCLUSION The first section of this report contains the radiological
' y environmental monitoring-conducted in the vicinity of the
/- Callaway Plant-during 1984. This-section contains nine (9) months of preoperational data and three (3) months of operational data. The comparison of the results of the radiological environmental monitoring conducted since the plant achieved initia1' criticality October 2, 1984 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 July and August 1984 is contained in Section 2 of this report. Since the monitoring was performed before the' plant achieved initial criticality on October 2, 1984, this data will be used as baseline information on the condition of vegetation prior to the plant start-up.
There were no plant modifications completed during 1984 with a unreviewed environmental question as shown in Section 3 of this report. ( ;/- i /

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program conducted during 1984 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 envi nment 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 op-ration of the Callaway Plant.
A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of 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 w .c . s
- - ~ ,j 2.0 ^ Description of the Monitorina Program .
Union Electric Company has contracted with Controls for Environmental Pollution, . Inc. starting May,1983, to determine the radiation levels existing in and around the
'Callaway Plant area.. Prior to this time, all analyses were performed by Radiation Management Company.
UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected weres milk, surface water, well water, shoreline sediment, bottom sediment, bedload sediment, washload sediment, soll, fish, vegetation, airborne particulates, airborne radiolodine and direct radiation (TLD). Information regarding sample preparation and analytical methods, instrumentation, O t
' detection limits, etc. used by CEP may be found in the First Quarterly Report for \ 1984.
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. r-3.1 Airborne Particulates and Radiolodine Airborne particulate samples were collected from fourteen monitoring staticns during 1984. 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 anrJ 1984 annual mean Gross Beta activity at each of the sampling locations follows.

- Based on only two samples collected during the First Quarter.
** Calculated without abnormal activities due to low volume of sampic (See Fourth Quarter Report 1984).
Gross Beta levels at all fourteen monitoring stations during 1984 are consistent with each other and do not indicate any anomolous data. Graphic presentations 4
p . () by ~ o f ~the Weekly Gross Beta activities for each collection location are presented in Figures 1 through 14. Invalid samples are those with anomolous Gross Beta activity due to air sampler malfunction (i.e. hour meter malfunction, sampler malfunction, etc.) or other circumstances ' which may have compromised the sample integrity. Figure 15 presents the Mean Weekly Gross Beta for all collection locations. The lowest Mean Weekly Gross Beta activity (0.012 1 0.001 pC1/m3) was observed from 10/11/84 - 10/18/84 while the week exhibiting the highest activity occurred 12/06/84 - 12/13/84 (0.04410.004 pCl/m3). Mean Quarterly Gross Beta activities were as follows: O , pCl/m3 January - March 1984 0.022 1 0008. April- June 1984 0.017 1 0004 July - September 1984 0.022 1 0009 October - December 1984 0.024 1 0009 Strontium-90 was detected in thirty-three of the quarterly coinposite samples during 1984 (See individual Quarterly Reports). Strontium-90 activity ranged from less than 0.002 pC1/m3t o 0.01210.009 (Site B2, First Quarter 1984). No Strontium-89 was detected in any of the quarterly composite samples from 1984 (Detection 1.imit 0.005 pC1/m3). Gamma-emitting nuc!! des of interest detected in quarterly air particulate composites include Cesium-137 and Beryllium-7. (See Individual quarterly O reports). - Airborne radiolodine was detected in four samples collected during the first two quarters of 1984. Airborne radiolodine activity ranged from less than 0.007 pCi/m3 to 0.0231 0.005 pCi/m3 (Site A5, 05/17/84-05/24/84) and may be attributed to a fluctuation in background levels. l 2 4 \ O l 1 i I O

1 l 3.2 Thermoluminescent Dosimetry 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 $2 locations and exchanged monthly. l I Listed below are the mean monthly readings ir ur/hr for all TLD's placed around ! the Callaway Site. These values are graphically presented in Figure 28. ur/hr l January 8.9 180 February 13.9 19 1 March 11.5 + 0.9 April 11.9 11

_ 4.6 Figures 16 through 27 present the ur/hr values obtained for each TLD station collected during each month of 1984. Half of the November TLD's and the transit control TLD had abnormally high readings. We have concluded that this excess exposure resulted from an unidentified radiation source inadvertently located adjacent to the packaged TLD's during transit between the TLD supplier and CEP. Evidence to support this conclusion includes the fact that only one of two parallel rows of TLD's packaged by the supplier showed the increased exposure and those readings show a gradient of exposure across the four TLD chips. This would indicate exposure to only one side of the package. In addition, a review of the site TLD locations'
. ._ _ .~ ._ __ ._ .__ . . _ _
l. k~ , 1 .
' ' M it, showed the exposed TLD's_ were located randomly around the plant site which would- not be indicative of a plant related exposure. As a - result, the TLD
~
~
stations that were excessively high were ' corrected by subtracting the excess: transit exposure from the results prior to reporting (See Fourth Quarter 1984 f Report). n _ - The -transit Control dosimeter for the December TLD's also had an abnormally high' reading the cause of which could not be determined. The problem did not recur in the January 1985 transit control dosimeter. To correct for the exposed ' control dosimeter, the average transit dose for the months of January through . ' October 1984" was subtracted from the gross readings obtained for , each
- =
monitoring site. As a result,' the Total Exposure and the Exposure Rate Values .
;for:several stations appear slightly higher than normal (see Fourth Quarter 1984 -
' Report).
,os Annual TLD's were placed in the field on~ June 3,1983 and were collected on y . August . 29, 1984. Data appearing in Table I are '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 1 substracted.from_ the gross readings obtained for each monitoring site. L . Due to the length of time the annual TLD's were exposed to the elements, eight of the Station numbers on the TLD's could not be positively identified. Total Exposure reading for these eight TLD's'did not appear anomolous and ranged ~ from 34.911.1 mrem to 47.911.5 mrem. The results appearing in Table I for
~
these stations are the average of the eight unidentified TLD badges. To ensure positive identification of annual TLD station numbers in the future, a second set
,z of identification stickers will be attached when the TLD's are changed out.

'3.3 Well Water Well water samples were collected monthly from three locations and analyzed for Gross Alpha, Gross Beta, Tritium, Stron' tium-89, Strontium-90 and Gamma-emitting nuclides. A summary of the Mean Gross Alpna and Gross Beta activities for Well Water samples may be found in Table II.
Collection location DOI (5.1 mi SE, Holzhouser Grocery Store / Tavern) had Gross Alpha activities ranging from less than 2.0 pCl/l to 5.0 12.0 pCi/l (collected 07/09/34) with an annual mean Gross Alpha activity of 2.811.2 pCl/1. Gross Beta activities from this collection location ranged from less than 3.0 pCl/l to 6.710.7 pCl/l with a 1984 mean Gross Beta of 2.01.6 1 pC1/l. A graphic presentation of the monthly Gross Alpha and Gross Beta results for we!! water samples obtained from co!!ection location D01 may be found in Figure 29. A Strontium-90 activity of 0.6 10.5 pCl/l was detected in the Well Water sample from collection location DOI 01/09/84. No detectable levels of Tritium or Strontium-89 were observed in any of the well water samples collected at Site D01 during 1984. Gross Alpha activities at collection location F 05 (1.0 mi SSE, Onsite Groundwater Monitoring Well) ranged from less than 2.0 pCl/l to 4.71.8 1 pCl/l (collected 02/13/84). The 1984 mean Gross Alpha activity for Site F05 was
- 2.01.3 1 pCl/1. Gross Beta activities at collection location F05 ranged from less than 3.0 pCl/l to 11.9 1 0.8 pCl/l (collected 03/12/84) with a mean annual Gross i
l Beta activity of 8.0 13.4 pCi/1. Figure 30 graphically presents the monthly Gross Alpha and Gross Beta activities for collection location F05. All we.1 water samples from collection location FO5 were less than 500 pCl/l for Tritium activity and less than 1.0 pCl/l for Strontium-89 activity. Strontium-90 detected in two 1984 Well Water samples (1.010.9 pCl/1, collected 06/11/84 and 1.210.7 5 pCi/l collected 07/09/84). All other samples collected at Site FOS during 1984 were less than 1.0 and 0.5 for Strontium-89 and Strontium-90 respectively. 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 1984. Gross Alpha activities ranged from less than 2.0 pCi/l to 5.0 12.0 pCl/l (collected 07/09/84) with a mean annual Gross Alpha activity of 2.6 11.4 pCl/1. Gross Beta activities ranged from less than 3.0 pCl/l to 12.910.8 pCl/l (collected 02/13/84). The mean annual Gross Beta activity for F15 was 6.11 2.8 pCi/1. All Well Water samples collected at Site FIS were less than the detection limits for Tritium, and Strontium 89, (500 pCl/l and 1.0 pCl/l respectively). Strontium-90 was detected in two 1984 Well Water samples collected from F15. A Strontium-90 activity of 1.7 11.1 pCl/l was detected in the sample collected 02/13/84 and an activity of 1.51.2 1 pCl/l for Strontium-90 was found in the sample collected 06/11/84. Overall, the 1984 mean annual Gross Alpha activity for all Well Water samples was 2.411.3 pC1/l. A 1984 mean Gross Beta activity for all Web Water samples was calculated to be 5.513 6 pC1/l. No gamma-emitting nuclides of interest were detected in any of the Well Water samples collected during 1984. O 4-4 4 d i 1 i I t l

1 - a - --- - - - I' c i 3.4 Surface Water [ Surface Water samples were collected from three locations on a monthly basis. ! Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, l ! Strontium-90 and for Gamma-emitting nuclides. A summary of the Mean Gross i t Alpha and Gross Beta activities for Surface Water samples may be found in Table E 111. i i Samples obtained from collection location 501 (4.8 mi SE, 84 feet upstream of l discharge, North Bank) yielded a 1984 annual mean Gross Alpha activity of 3.02.4 1 pCi/l with a range from less than 2.0 pCi/l to 9.7 2.5 1 (collected 05/14/84). The mean annual Gross Beta activity for Sol was calculated to be 8.614.8 pCi/l with a range of Gross Beta activity from 4.210.6 pCi/l to 21.61.0 1 pCi/l (collected 07/09/84). The monthly Gross Alpha and Gross Beta results are graphed in Figure 32. No Strontium-89, Strontium-90, or Tritium activities were observed in any of the Surface Water samples collected from location 501 during 1984. l The river composite sampler located at S01 was discovered to be malfunctioning on June 13, 1984. The cause of this malfunction was the failure of the time delay relay which operates the air lift pump. The procurement time for the replacement relay caused the sampler to be out of service until October,1984. l During this time grab samples were collected and composited on a monthly basis. If procurement and reliability of this relay continues to be a problem, a design change will be initiated. 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
l , g i 8.813.5 pCi/l (collected 06/11/84). The 1984 mean, Gross Alpha activity from this location was 3.812.7 pCi/1. An annual mean Gross Beta activi{y of 8.2 14.1 pCi/l was observed while the range of Gross Beta activity from this site was from less than 3.0 pCi/l to 14.710.8 pCi/l (ccU;cted 05/14/84). Figure 33 shows the monthly Gross Alpha and Gross Beta results draphically. ' All Surface Water samples collected from location 502 during 1984 were less than the detection limits for Tritium, Strontium-89 and Strontium-90 (500 pCi/1,1.0 pCi/l and 0.5 pCi/1, respectively). '
~. .
Figure 34 presents the monthly Gross Alpha and Gross Beta results for samples collected during 1984 from collection location 503 (68 mi E, City of St. Louis Water Intake). A range of Gross Alpha activity from less than 2.0 pCl/l to 8.313.4 pCi/l (collected 02/06/84) was observed in the samples collected from location 503. The 1984 mean Gross Alpha acti<ity _for samples from this location was calculated to be 3.812.9 pCl/1. Results of Gross Beta analyses for Surface Water samples from Location SO3 ranged from less than 3.0 pCi/l to 17.510.9 pCi/1. A 1984 annual Gross Beta activity of 7.7 14.2 pCi/l was observed for this site. Strontium-90 was detected in one Surface Water sample collected during 1984 from collection location 503 (1.310.9 pCi/1, collected 06/08/84). No Strontium-89-or Tritium were detected in any of the Surface Water samples collected from this location during 1984. The 1984 mean a; .ual Gross Alpha and Gross Beta activities for all Surface Water ' samples were 4.8 1 6.8 pCi/l and 8.214.3 pCl/1. No gamma-emitting nuclides of interest were detected in the 1984 Surface Water samples. O

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 May 5, 1983. This quarterly report presents data for the months of January,' February, and March,1984. 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, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radiolodine and direct radiation (TLD).
- Analytical results are presented and discussed along with other pertinent information.

1.0 Introduction To comply with Federal and State regulations and in its concern to maintain the quality of the local environment, UEC began its pre-operational radiological monitoring program in April,1982. The objectives of the pre-operational radiological monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to provide the experience from which to develop a meaningful operational program of radiological assessment; and 3) to develop trip notification levels for operational evaluation. Program modifications, should they prove necessary, will be described in each quarterly report.
A number of techniques will be used to distinguish Callaway Plant effects from other g 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. The pre-operational data is critical because these measurements are used g for comparison of both on-site and off-site 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. 2.0 Description of the Monitoring Program Union Electric Company has contracte.d with Controls for Environmental Pollution, Inc. starting May 1983, to determine the radiation levels existing in and around the Callaway Plant area.

Analytical Precedures The analytical procedures described below are those routinely used by CEP to analyze samples. 3.1 Airborne 3.1.1 Gross Alpha and Gross Beta : The glass-fiber filter, type A/E (99 percent removal efficiency at I micron particulate),'is placed into a'two-inch stainless steel planchet and counted for Gross Alpha and Gross Beta' radioactivity using a low background, internal gas flow, simultaneous proportional counter (Beckman Wide Beta II), or by using a low background simutaneous counter (Tennelec LB5100).
' 3.1.2 Gamma hLeLi 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, p- if present, identified and quantized.
v. 3.1.3 Strontium-89 and Strontium-90 The composited filters are dissolved in acid and brought to a known volume. Strontium and Yttrium carriers are added and the solution is evaporated to dryness. The resulting residue is taken up in dilute acid. The Yttrium-90 is extracted 6 sing five percent D2EHPA (Di ethlyhexyphosphoric acid) in toluene. After the ingrowth period has been established back extracted into an aqueous phase, precipitated as the oxalate, counted in a low background proportional counter (Beckman Low O Beta ii), eed ceicuieted es Strontium-90 activity. The eseeoes ghese is evaporated to a low volume, precipi+2ted with fuming nitric A:d.
o . redissolved in water, made basic with dilute ammonium hydroxide and h precipitated as the oxalate. The dried precipitate is counted in a low background proportional counter (Beckman Low Beta II) and the Strontium-89 activity is determined by subtracting the preciously measured Strontium-90 activity and its corresponding Yttrium-90 ingrowth from the measured gross Strontium activity. 3.1.4 Iodine-131 3.1.4.1 Alkaline Leach Method The radioiodine is stripped off activated charcoal by reduction using concentrated ammonium hydroxide (NH4 0H) 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 Iodine. It is then back extracted using 0.2% hydrazine solution, which supplies further O 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 (AgI). The dried precipitate is weighed for recovery and counted for Iodine-131 in a thin window O gas flow proportional counter (Beckman Low Beta 'll) having a forty-one percent efficiency 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 Iodine _131 activity determined using Method 3.1.2. 3.1.5 Direct Radiation Direct radiation measurements were taken using Thermoluminescent g Dosimeters (TLD's).

7.0 Quali4 Control Program h CEP employs a multi-faceted Quality Control Program designed to maintain high performance of its laboratory. The overall objectives of the program are to: 1.) Verify that work procedures are adequate to meet specifications of UEC. 2.) Coordinate an in-house quality control program independent of external programs, to assure that CEP is operating at maximum efficiency. Objectives are met by a variety of procedures that oversee areas of sample receipt and handling, analysis and data review. These procedures include standard operating procedures, known and unknown spike analysis, blank analysis, reagent, carrier and nuclide standardization as well as participation in the U.S. Environmental Protection Agency's Interlaboratory Cross-check Program (See Appendix A for EPA Cross-check Results). CEP's Quality Assurance Program is reviewed and revised (when necessary) on a regularly scheduled basis. This review assures that the program meets all current regulatory guidelines as well as maintaining the highest standards of quality assurance practices. O 8.0 Data Interpretations and Conclusions This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period. Analysis and review of data incorporates various techniques from historical comparison to statisical evaluation. Results which do not compare with the historical range are recalculated for verification. If the recalculation verifles 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 g L.
m V, analysis is made. Results which are out!!ers with respect to two standard deviations of the mean are considered out of baseline range or anomolous. 8.1 Airborne Particulates and Radiolodine Airborne particulate samples were co!!ected from fourteen monitoring stations during the first quarter of .1984. However, due o road construction in the vicinity of Sites A2 and A6, these stations were relocated to new positions to allow for the wider roads. Therefore, these two sites were not in operation for three weeks during this quarter. In addition, Site Al was not operational for three weeks due to electrical problems, and Site A4 and B2 were deleted from the air monitoring program during the third week of this quarter. These two monitoring locations were replaced by two new monitoring stations: Sites A8
. and A9 which were put in operation during the sixth week of the first quarter of 1984. Airborne particulate stations (Al-A9) were also collection sites for airborne radiolodine.
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 pC1/m3. l , Collection Location Minimum Maximum Site A1 0.012 1 0001 0.037 1 0002 l Site A2 ' O.011 1 0001 0.027 1 0002 !

The highest mean Gross Beta activity during the report period was observed at Site B2, with a mean activity of 0.03610.019 pCi/m3. Mean Gross Beta activities O at the other sites varied from 0.018 pC1/m3 at Sites Site A8 and A9 to 0.03020.010 pCi/m3 at Site A4. Mean weekly Gross Beta activities ranged from a low of 0.01310.002 pCi/m3 during the collection periods of 03/15/84 - 03/21/84 to a high of 0.03610.013 pC1/m3during the collection period of 12/29/83 - 01/04/84.

8.2 Thermoluminescent Dosimetry h 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 containing 0.022 inch copper backing to shield out low energy radiation. (Shields approximately 50% fo the gamma rays at 40 KEY.) 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. O As can be seen from Tables IX through XI, exposure levels for all monitoring locations are consistent with the altitude and geology of the area. No anomolous TLD data was seen during the first quarter of 1984.

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-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 2.0 pC1/1 to 8.313.4 pCi/l and less than 3.0 pCi/l to 8.910.7pCi/1, respectively. The positive Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40. All Tritium data from surface water samples were below the detection limit of 500 pCi/1. O Results of Strontium-90 and Strontium-89 analyses were all below the respective detection limits of 0.5 pCl/l and 1.0 pCi/1.

i- 8.6 - Fish Five species of fish were collected from three locations on a monthly basis. Types of fish collected during this report period were: freshwater drum, black bullhead, bigmouth buffalo, carp, goldeye, river carpsu:ker, shorthead redhorse, sauger, shovelnose sturgeon, white sucker, white 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 XXII thru XXVII. Gross Alpha levels for all samples ranged ~between the detection limit of 0.3 pCi/g to 2.110.8 pCl/g. Gross Beta activities ranged from a low of 3.210.5 pCi/g to a high of -13.2 10.8 pCi/g (sample CA-AQF-C, freshwater drum, collected 03/14/84). 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 Strontium-90 activities ranged from non-detectable to 0.66 1 044 pCi/g. All fish data for Strontium-89 were below the detection limit of 0.05 pCl/g. Results of Gamma Spectral Analysis may be found in Tables XXIII, XXV, and XVII. One fish (freshwater drum, collected 03/14/84 at location A) exhibited a level of 0.11310.055 Cs-137 activ.ity. In addition, one fish sample demonstrated a Manganese-54 activity of- 0.1091 0.051 pCi/gm and a Cobalt-60 activity of-0.21610.034 pCi/gm. (shorthead redhorse, collected 01/25/84 at location A.)

Isotopic Detection Limits and Activity Determinations g 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.
Background
Gross O
/ ~
If a sufficient number of replicate analyses are run, it is to be expected that the results O would fall 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 l report the mean 1one or two standard deviations as the final result. In routine analysis such
- replication is not carried out, and it is not possible to report a Gaussian standard 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
'(V 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 detec, tion 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 Any counter will show a certain counting rate without a sample in position.
This background countin'g rate comes from several sources: 1) natural environmental radiation from the surroundings, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background counting rate will depend on the amounts of these types of radiation and
. the sensitivity of the counter to the radiation.
- 4. Background and Sample Counting Time The. amount of time devoted to the counting of the background depends on the level of activity being measured. In general, with low level samples, this time should be about equal to that devoted to counting a sample.
l 1
- 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 formula: g _. _8 C+B 1.96
-T2 -
A= C-B 3 (2.22)(V)(T) (R)(E)(e- At) (2.22)(V)(R)(E)(e- A t) WHERE: O A= Activity as pCl per unit sample mass or volume. C= Sample counts. B= Background counts. V= Sample volume or mass analyzed. E= Counter efficiency in cpm /dpm. 2.22 = Numerical constant to convert disintegrations per minute to picocuries. (e - At) = Decay factor to correct the activity to time of collection. T= Counting time in minutes for sample and background. 1.96 e Statistical constant for the 95% confidence level. R= Chemical recovery or photon yield. g
.g.
C/ CEP uses the following method to determine lower limit of detection (LLD) as per 'NRC
' Regulatory Guide 4.1, Rev.1, " Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants," and the NRC Branch Technical Position, November 1979, "An
- Acceptable Radiological Environmental Monitoring Program". The LLD is defined, for purposes of this guide, as the smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with 95%
probability with, only 5% probability of falsely concluding that a blank observation -
' represents a "real" signal.
For a particular measurement system (which may include radiochemical separation): LLD = 4.66 sb E
- V
- 2.22 Y exp (. Aa t)
WHERE: LLD is the "a priori" lower limit of detection as defined above (as pCi per unit mass or volume).
'. 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 picocurie. Y is the fractional radiochemical yield (when applicable). A is the radioactive decay constant for the particular radioisotope. at is the elapsed time between sample collection (or end of the sample collection period) and time of coun, ting. The value of sb used in the calculation of the LLD for a particular e 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. i

1 1 1 v . i Abstract . Controls for Environmental Polluti6n, Inc (CEP) has conducted a pre-operational radiological
-monitoring program for Union-Electric Company (UEC), Callaway Plant, Unit 1, since May ~
5,1983. This quarterly repo.rt presents data for the months of April, May, and June,1984. Evaldation 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 radiolodine and direct radiation (TLD). 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

1.0 Introduction h To comply with Federal and State regulations and in its concern to maintain the quality of the local environment, UEC began its pre-operational radiological monitoring program in April,1982. The objectives of the pre-operational radiological monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to provide the experience from which to develop a meaningful operational program of radiological assessment; and 3) to develop trip notification levels for operational evaluation. Program modifications, should they prove necessary, will be described in each quarterly report.
A number of techniques will be used to distinguish Callaway Plant effects from other h 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 I locations. The pre-operational data is critical because these measurements are used for comparison of both on-site and off-site locations. In addition, results of the l 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. l 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 a'rea. O '[
.UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected this quarter were: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, shoreline sediment, fish,
- airborne particulates, airborne radiolodine and direct radiation (TLD).
Locations of the monitoring sites are shown in Figures I 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 II.

7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter Report 1984 (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 two standard deviations of g the mean are considered out of baseline range or anomolous. 8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from April 5,1984 thru June 28, 1984. Seven of the airborne particulate stations were also collection sites for airborne radioiodine (See Table IX). 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 . @

Three airborne radioiodine samples exhibited levels of Iodine-131 greater than CEP's detection limit (0.007 pC1/m3). However, these samples are well below the lower limit of detection noted in Table 4.12-1 of Union Electric Company's Technical Specifications (0.07- pCi/m3). The lodine-131 levels observed during Lthis quarter may be attributed to fluctuations in background levels. 4

t h*- 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 containing 0.022 inch copper backing to shield out low energy radiation. (Shields approximately 50% fo the gamma rays at 40 KEV.) The TLD's were placed at 52 locations and exchanged monthly. Data appearing in Tables X thru XII 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. O As can be seen from Tables X through XII, exposure levels for all monitoring locations are consistent with the altitude and geology of the area. No anomolous TLD data was seen during the second quarter of 1984. t

.A 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 XV and XVI. Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities of less than 2.0 pCi/l to 9.712.5 pCl/l and 4.210.6 pCl/l to 14.710.8 pCi/1, respectively. The positive Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40. All Tritium data from surface water samples were below the detection !!mit of 500 pCl/1. Strontium-90 was detected in one of the surface water samples collected during the second quarter of 1984 (CA-SWA-503 collected 06/08/84). No Strontium-89 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 Five species of fish were collected from three locations on a monthly basis. Types of fish collected during this report period were: paddlefish, freshwater drum, shortnose gar, longnose gar, smallmouth buffalo, bigmouth buffalo, carp, goldeye, bluegill, river carpsucker, blue catfish, flathead catfish, 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 XXIII thru XXVIll. Gross Alpha leveis for all samples ranged between the detection limit of 0.3 pCl/g to 1.5 10.5 pC1/g (sample CA-AQF-A, Carp, collected 04/24/84, and sample CA-AQF-C, Carp, collected 04/24/84). Gross Beta activities ranged from a low of 2.6 10.5 pC1/g to a high of 13.1 0.8 1 pC1/g (sample CA-AQF-C, Flathead g Catfish, collected 05/22/84). 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 pCl/g. Five fish collected from Locations A and D in the second quarter exhibited Strontium-90 activities. Strontium-90 activities ranged from non-detectable to 0.6010.40 pCl/g. 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 XXIV, XXVI, and XVIII. Three fish exhibited levels of gamma-emitting nuclides of interest slightly above the detectable levels.

Y gs 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 May 5,1983. ~ This quarterly report presents data for the months of July, August, September,-1984.
' 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 clllected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radioiodine and direct radiation (TLD). Q . 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.
k s
.g.
1.0 Introduction h To comply with Federal and State regulations and in its concern to maintain the quality of the local environment, UEC began its pre-operational radiological monitoring program in April,1982. ' The objectives of the pre-operational radiological monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to provide the experience from which to develop a meaningful operational program of radiological assessment; and 3) to develop trip notification levels for operational evaluation. Program modifications, should they prove necessary, will be described in each quarterly report.
A number of techniques will be 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. 'Ihe pre-operational data is critical because these measurements are used l for comparison of both on-site and off-site 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. 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.
h
a
- UEC personnel collected the samples and shipped them to CEP for analysis. 'Ihe type of samples collected this quarter were: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radiciodine and direct radiation (TLD).
Locations of the monitoring sites are shown in Figures I and 2. Table I presents the
! monitoring sites and the respective samples collected. Sample collection frequency for each of the monitoring locations is depicted in Table II.
Meanings of sample type codes used in Table I are as follows: Code Sample Collected AIO Air Iodine APT Air Particulate AQF . Fish AQS , Sediment FPL Leafy Green Vegetables IDM TLD MLK Milk SOL- Soil SWA , Surface Water WWA Well Water 4 O

7.0 Quality Control Program A summary of CEP Quality Controls Program is contained in the First Quarter Report 1984 (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 d' etermined that the results obtained are accurate, a statisical analysis is made. Results which are outliers with respect to two standard deviations of g the mean are considered out of baseline range or anomolous. 8.1 Airborne Particulates and Radioiodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from June 28, 1984 thru September 27,1984. Nine of the airborne particulate stations were also collection sites for airborne radioiodine (See Table IX). 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 pC1/m3 h O

0.010 1 0002 0.026 1 0002 Table VIII, Gross Beta in ~ Airborne Particulates, shows . that the Gross Beta b_ O - activity ranged ~from a minimum of 0.00010.002 pC1/m3 at Site B3 during the collection period of 07/19/84-07/26/84 and at Site B6 during the collection period of 07/26/84-08/02/84 to a maximum of 0.07410.005 pCi/m3 at loctation B5 during the collection period 08/16/84-08/23/84. LHowever, the air sampler at Station B6 during the week of 07/26/84-08/02/84 blew a fuse shortly after it was started. As a result, the pump only ran for 0.5 hour during the week. In addition, the air sampler at Site B5 malfunctioned during the week of 08/16/84-08/23/84 resulting in a sampling time of 63.1 hours. The flow rate and the actual volume of air sampled could not be verified. Therefore, the elevated Gross Beta activity for this Site (0.074 0.005 1 pC1/m 3) may be the result of the low volume of air used in the calculation. The air sampler at Site A2 during the collection period 08/16/84-08/23/84 also malfunctioned. The sampler only operated for 2.3 hours. . Due to the low volume of air sampled at this location the Gross Beta activity calculated to be 0.01610.074 pC1/m3 . d
The highest mean Gross Beta activity during the report period was observed at Site A7, with a mean activity of 0.02810.015 pCi/m3 Mean Gross Beta activities at the other sites varied from 0.0181 0.004 pCl/m3 at Site B8 to 0.02510.015 pCi/m3 at Site B5. Mean weekly Gross Beta activities ranged from a low of 0.01510.006 pCi/m3 during the collection period of 07/26/84-08/02/84 to a high of 0.03210.013 pCi/m3 during the collection period of 08/16/84-08/23/84.

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 containing 0.022
~ inch copper backing to shield out low energy radiation. (Shields a'pproximately 50% of.the gamma rays at 40 KEV.) The TLD's were placed at 52 locations and exchanged monthly.
Data appearing in Tables X thru XII 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.
>Q As can be seen from Tables X through XII,' exposure' levels for all monitoring locations are consistent with the altitude and geology of the area. No anomolous TLD data was seen during the third quarter of 1984.

8.6 Fish $ Five species of fish were collected from three locations on a monthly basis. Types of fish collected during this report period were: paddlefish, freshwater drum, blue sucker, shortnose gar, longnose gar, white bass, smallmouth buffalo, carp, goldeye, river carpsucker, blue catfish, flathead catfish, gizi:ard 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 XXIII thru XXVIII. Only one fish collected during the third quarter exhibited positive levels of Gross Alpha activity (sample CA-AQF-A, White Bass, collected 09/05/84). All other fish collected this' quarter had Gross Alpha activity less than 0.3 pCi/1. Gross Beta activities ranged from a low of 3.720.2 pC1/g to a high of i1.610.8 pCi/g g (sample CA-AQF-A, Gizzard Shad, collected 07/17/84). 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 l pCi/g. Twelve fish collected in the ' third quarter exhibited Strontium-90 l l activities. Strontium-90 activities ranged from non-detectable to 0.7210.17 l pCi/g. l l Strontium-89 was detected slightly above the detection Ilmit in the five fish collected from Location A during July. The range of activity in these samples was from 0.1120.04 pCi/g to 0.2220.05 pCi/g. No other fish collected during the third quarter had detectable Strontium-89 activity. h o _ -

. Results .of Gamma Spectral' Analysis may be found in Tables XXIV, XXVI, and XVIII. .Nine fish exhibited gamma-emitting nuclides of interest slightly above the detectable levels. -

8.7 Milk $ Milk samples were collected from two locations, the Green Farm and the Davidson Farm. 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 detected in one of the milk samples during this period. The sample collected 08/27/84 from the Green Farm had an Iodine-131 activity of 1.41 0.7 pCi/1. No other Iodine-131 activity was detected in any of the third quarter milk samples. Strontium-90 levels varied from less than 1.0 pCi/l to 3.531.5 pCi/l in the sample collected 07/09/84 from the' Green Farm. All milk samples collected during this report period were below the detection limit of 2.0 pC1/1 for Strontium-89.

# Controls for Environmental Pollution,'Inc. (CEP) has conducted the 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, Dece'mber,1984. Evaluation of the 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, shoreline sediment, bottom sediment, bedlosd sediment, washload sediment, fish, soil, airborne particulates, airborne radiolodine 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 Environ nental . Pollution, Inc., are discussed. 4 6

1.0 Introduction h To comply with Federal and State regulations and in its concern to maintain the quality - of the local environment, UEC began its Callaway Plant radiological monitoring program in April,1982. The objectives of the pre-operational radiological monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) monitor potential critical pathways of radioeffluent to ' man; 3) to determine radiological impact on the environment caused by the operation of the Callaway Plant.
Program modifications, should they prove necessary, will be described in each quarterly report. A number of techniques are used to distinguish Callaway Plant effects from other g sources, 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 Callway County, Missouri.- The plant consists of a 1150 MWe pressurized water reactor, which achieved initial criticality on October 2,1984. 2.0 Description of the Monitoring Program Union Electric Company has contracted with Controls for Environmental Pollution, h Inc. starting May 1983, to determine the radiation levels existing in and arou..d th: Callaway Plant area.
, ji V' UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected this quarter were: milk, vegetation, surface water, well water, shoreline sediment, bottom sediment, bedload sediment, washload sediment, fish, soil, airborne particulates, airborne radioiodine and direct radiation (TLD).
. Locations of the monitoring sites are shown in Figures I and 2. Table I presents the monitoring sites and the respective samples collected. Sample collection frequency for each of the, monitoring locations is depicted in Table IL V 'Ings of sample type codes used in Table I are as follows:

7.0 Quality Control Program h A summary of CEP Quality Controls Program is contained in the First Quarter Report 1984 (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 analyzeu 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 two standard deviations of g the mean are considered out of baseline range or anomolous. 8.1 Airborne Particulates and Radiolodine Airborne particulate samples were collected from each of the fourteen monitoring stations on a weekly basis from September 27, 1984 thru December 27,1984. Nine of the airborne particulate stations were also co!!ection sites for airborne radiciodine (See Table IX). 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. Sixteen air filters collected during the Fourth Quarter of 1984 had low volumes of air sampled due to electrical or equipment failures (See Tables VII and Vill). Because of the low volume of air sampled, the Gross Beta activity of these lE . y . . 1
'k
/
'd samples often appear to be anomolous. Therefore, the Gross Beta activities for
.these samples were not included in the calculations of the mean Gross Beta
" activities for the respective sites, or the mean weekly Gross Beta activities.
In addition, during the collection period from 11/22/84-11/29/84 three air filter and charcoal cartridge samples arrived at CEP labelled as being collected from Site A3. No samples were received for Site A5 and B3 for this collection period. No Iodine-131 activity was detected in any of the airborne radiciodine samples
- and the Gross Beta activities in these three air particulate samples were 0.02120.002 pC1/m3, 0.01930.002 pC1/m3 and 0.01920.002 pC1/m3 (based on the average volume of air sampled for all air monitoring stations between 11/22/84
. and 11/29/84). These three e!r particulate samples wer not' included in the
. quarterly composites for Sites A3, AS, and B3 and are .ot included in Table VIII.

The highest mean Gross Beta activity during the report period was observed at Site A5, with a mean activity of 0.02930.010 pC1/m3. Mean Gross Beta activities at the other sites varied from 0.02130.007 pCl/m3 at Site A8 and Site B8 to 0.02830.010 pC1/m3 at Site A3. g Mean weekly Gross Beta activities ranged from a low of 0.01230.001 pCl/m3 during the collection period of 10/11/84-10/18/84 to a high of 0.04430.004 pCi/m3 during the collection period of 12/06/84-12/13/84.

Ilowever, due to the variability of sample volumes in the air filters, the actual detection limit for Berylilun-7 may be lower than 0.010 pC1/m3 For example, based in the calculation shown in First Quarter Report, Appendix B, an alt filter composite with c total volume of 5563.0 m3 will han a detection lio.it for j e f 3 Beryllium-7 of 0.005 pC1/m3. Therefore, the values reported for Beryllium-7 are based on detection limits calculated for each sample and not 0.010 pCi/l listed in Table IV. Results of the airborne radiolodine analyses may be found in Table IX. No lodine-131 activity was detected in any of the alrborne radiolodine samples collected during the third quarter.

3.2 Thermoluminescent Dosimetry h'l 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 containing 0.022 inch copper backing to shield out low energy radiation. (Shields approximately 50% of the gamma rays at 40 KEV.) The TLD's were placed at 52 locations and exchanged monthly. Data appearing in Tables X thru Xil 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. Half of the November TLD's and the transit control TLD had abnormally high readings. We have concluded that this excess exposure resulted from an unidentified radiation source inadvertently located adjacent to the packaged TLD's during transit between the TLD supplier and CEP. Evidence to support this conclusion includes the fact that only one of two parallel rows of TLD's packe;cd by the supplier showed the increased exposure and those readings show a gradient of, exposure across the four TLD chips. This would indicate exposure to only one side of the package. In addition, a review of the site TLD locations showed the exposed TLD's werc located randomly around the plant site which would not be indicative of a plant related exposure. As a result, the TLD stations that were excessively high were corrected by subtracting the excess transit exposure from the results prior to reporting. 9 The transit Control dosimeter for the December TLD's also had an abnormally high reading. The cause of this high reading could not be determined. The problem did not recur in the January,1985 control dosimeter. To correct for the exposed control dosimeter, the average transit dose for the months of January thru October -1984 were subtracted from the gross readings obtained for each monitoring site. To corree.t for the exposed control dosimeter, the average transit dose for the months of January through October 1984 was subtracted from the gross readings obtained for each monitoring site. As a result, the Total Exposure and the Exposure Rate Values for several stations appear slightly higher than normal. The Dece.ober TLD's at Stations 36 and 41 were only in the field from 12/20/84-
.m e
12/28/84. Analyses of these dosimeters exhibited net exposures of 12.110.6 mrem and 10.910.7 mrem, respectively which are comparable to the net exposures seen at other sites. Due to the fact that the exposure time of the Site 36 and Site 41 TLD's was approximately one third of the norrnal exposure time, the calculated hourly exposure rates are not consistent with those from other sites. Due to the high accuracy of the CaSO4 dosimeters and the exposure rates c,. for t.ll other sites for a full exposure period and for Stations 36 and 41 during previous inon'ths, it is believed that the December data for Stations 36 and 41 is anomolous and is not representative of the direct radiation levels for these sites. s rm ! v-

4 Samples -were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90,
' Strontium-89, and. by. Gamma Spectrometry. Results are summarized in Tables XV and XVI. '
Gross Alpha and Gross Beta analyses of surface water sam;les showed a range of activities of less than 2.0 pCi/l to 6.212.2 pCl/l and 3.710.5 pCi/l to 12.610.9 pCi/1, rehpectively. The. positive Gross Beta activities could be attributed to naturally occurring isotopes, such as Potassium-40. The surface water sample collected 10/30/84 at location 501 was inadvertently
, : mistaken to be a sediment sample. The error was not detected until most of the water in the sample was discarded. Tne Gross Alpha and Gross Beta analyses were performed on the remaining supernate and on the solid material. The Gross -
Alpha and Gross Beta activities on the dissolved portion of the sample were 2.112.4 pCi/l and 6.4 11.3 pCl/1, repectively. The Gross Alpha and Gross Beta
-activities, on the suspended portion of the sample were 7.81.4 1 pCl/g and 10.51 1.2 pC1/g, respectively. The total amount of suspended material in the
= sample was 0.7 g. Assuming that this material would have been homogeneously distributed throughout the sample by shaking prior to analysis, the values for
.' Gross Alpha and Gross Beta found in Table.XY were calculated by adding the dissolved activity to the amount of activity in the suspended material expected in. the same volume, of sample. . Tritium and Gamma Spectral analysis were performed on the sample prior to separation of the suspended and dissolved h; , fractions. Insufficient sample was remaining to perform the Streatium-89 and Strontium-90 analysis.
-c- .
T All Tritium data from surface water samples were below the detection limit of 500 pCi/1. No Strontium-89 or Strontium-90 were detected in any of the Surface Water samples collected this quarter.

- Alpha, Gross Beta, Strontium-90 ~ Strontium-S9, and by Gamma Spectrometry.
Results are summarized in Tables XVII thru XXII. 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/r pCi/g Washload 4.6 - 10.8. 7.2 - 16.3 Bedload 1.0 - 8.9 0.9 - 12.9 Bottom 1.2 - 4.0 1.5 - 5.1 All sediment samples collected during the fourth quarter had less than detectable levels for Strontium-39 and Strontium-90 activities. Gamma Spectral analysis of the sediment samples collected during this report period are detailed in Tables XVill, XX and XII. Bottom sediment samples showed the greatest observance of gamma-emitting isotopes. A shoreline sediment sample was collected from Location C on 10/25/34 and
~
analyzed for Strontium-90 and by Gamma Spectroscopy. No Strontium-90 was detected in the shoreline sediment sample. A Cesium-137 activity of 0.0201 0.008 pCi/g was observed ,in this sample. No other gamma-emitting nuclides of interest were detected in the shoreline sediment sample collected f) s . during the fourth quarter.

8.6 Fish h Five species of fish were collected from three locations on a monthly basis. Types of fish collected during this report period were: white crappie, freshwater drum, sauger, shorthead redhorse, stripped bass, white bass, smallmouth buffalo, bigmouth buffalo, carp, goldeye, ris er carpsucker, blue catfish, flathead catfish, 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 XXIII thru XXVill. Thirteen fish collected during the fourth quarter exhibited positive levels of Gross Alpha activity. The range of Gross Alpha activity in fourth quarter fish was from less than 0.3 pCl/g to 2.5f 1.0 pCl/g. Gross Beta activities ranged from a low of 3.9 10.5 pCi/g to a high of 12.0 0.7 1 pCl/g (sample CA-AQF-D, Channel g Catfish, collected 10/19/84). Gross Beta activities seen in fish samples could be attributed to naturally occurring isotopes (e.g. Potassium-40). No Strontium-89 or Strontium-90 activity was detected in any of the fis'h samples collected during the fourth quarter. Results of Gamma Spectral Analysis mny be found in Tables XXIV, XXVI, and XVill. Fourteen fish exhibited gamma-emitting nuclides of interest slightly above the detectable levels.

8.8 Vegetation One Vegetation sample was collected during the fourth quarter: turnip greens j from the Hazlett Farm on 10/18/84. This sample was analyzed for Gross Alpha, Gross Beta, Iodine-131, and by Gamma Spectrometry. No Gross Alpha activity was- detected in the vegetation sample collected during the fourth quarter. A Gross Beta activity of 9.10.2 3 pCl/g was detected in this sample. This Gross Beta activity is consistent with levels of naturally occurring isotopes commonly found in vegetation.
, No Iodine-131 or gamma-emitting isotopes of interest were detected in any of g the vegetation samples.

Soil samples were collected from eleven locations during the fourth quarter of 1984. Soll was analyzed for Gross Alpha activity. Gross Beta activity, and by gamma spectral analysis. Results of these analyses may be found in Tables XXXI and XXXII. Gross; Alpha activity in the soll samples ranged fr6m a low of 3.620.6 p'C1/g at the Callaway Plant Forest, Ecology Plot Fl to a high of 6.220.8 pCl/g at the Callaway Plant Forest, Ecology Plot F9. Gross Beta activities ranged from 4.6+0.6 (Callaway Plant Forest, Ecology Plot F1) to 7.320.6 (Callaway Plant Forest, Ecology Plot F9). O 1 Ceslum-137 was detected in all soll samples collected during the fourth quarter j of 1984. Cesium-137 activity ranged from 0.42320.014 pCl/g to 1.1920.02 pC1/g. In addition, Manganese-54 was detected at two locations, Callaway Plant Forest, 1 Ecology Plot F1 and Ecology Plot F9.' Cobalt-60 was observed at the Callaway J Plant Prairie, Ecology Plot PR4 and the Hazlett Farm. The Hazlett Farm and the Callaway .

1.1 INTRODUCTION
1.1.1 Purpose - - - - - - - -- - Union Electric Company (UE ), in response to Nuclear Regulatory } Commission (NRC) mandate, has undertaken a program to monitor the poten-tial impacts of cooling tower drift on the local flora surrounding the UE Callaway Plant in Callaway County, Missouri. It is the aim of the program at this time to establish a database of existing vegetation con-j ditions at ~ the Callaway Plant site using color infrared aerial pho-i tography and to document any naturally occurring vegetation stress. Interpretation of aerial photographs has been used to prepare this base-line information . This has been supplemented by ground truthing to ensure accurate interpretation of photographs and field phytopathological I l assessment to identify the causes of any vegetation stress encountered. ! u
- In the future it will be possible to periodically re-examine the vegeta-tion to determine if any vegetation stress that is encountered may be I t
attributable to operation of the Callaway Plant cooling tower. This pre-sent work complements other vegetation ecology monitoring undertaken at the study site. Work performed in 1973-1975, 1981, and 1983-1984 con-centrated on a set of permanent ecology plots and used classical botani-cal techniques to describe the vegetation community at the Callaway i
. Plant.

' 1.2 EXECUTIVE SUMPERY h- Baseline environmental information on the condition of vegetation at the Callaway Plant site has been developed through infrared aerial photography, photointerpretation and ground truthing of stressed vegeta-tion, vegetation mapping and phytopathological diagnosis of stressed vegetation during July and August,1984.
Ten UE terrestrial study plots were photographed with infrared film at a scale of 1" = 250'. Residual lands were photographed at a scale of - 1"*= 1000'. Photointerpretation was performed based upon the differen-tial infrared reflectance charac'teristics of healthy versus stressed tree cover. The infrared photographic record was then verified with the on-site appearance of stressed vegetation during a ground truthing field inspection. On-site and laboratory phytopathological diagnoses were made for stressed vegetation identified from aerial photography. A Callaway Plant site vegetation map was produced which showed the location of stressed vegetation. Seventy-one individual stressed deciduous trees, two individual stressed evergreen trees and six tree damage zones were plotted on the vegetation map. Oak wilt was found to be the most common cause for stressed vegetation located at the study site. The second most common cause for vegetation stress was mechanical injury including frost cracking, lightning strike and branch and bark breakage. Other causes of vegetation stress were Dutch Elm disease, root and butt . rot, herbicide damage and general dieback. The spread of oak wilt was expected to con-tinue in the future. Some tree mortality and decline due to cold winter temperatures and summer moisture stress were al so expected since O . 2 . 0 4
I winter / spring Mitions in 1983 and 1984 were colder and wetter than usual and summer conditions in 1980,1983 and 1984 were drier and hotter Q than usual.

2.1 STUDY METS 005 Applied Biology, Inc. ( A81) has coordinated infrared aerial pho-(vQ tography, photointerpretation and ground truthing of stressed vegetation, vegetation mapping and phytopathological assessment of stressed vegeta-tion for the Callaway Plant site. 2.1.1 Aerial Photoaraphy Aerial photography for this project was flown from 1242 to 1318 hours on 18 July 1984 by Walker and Associates, Inc. of Fenton. Missouri on a subcontract basis for ABI. 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 UE terrestrial study plots were photographed with 60 percent forward overlap at a scale of 1" = 250'. The residual lands of the plant O site -re ,wto ra,hed with 60 perc-t forward -eria, and 30 percent side lap 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 Witch may occur along the edges of an aerial photographic exposure. Dupitcate sets of positive film transparencies and positive prints were produced in 9" by 9" format. 2.1.2 Photointeroretation Analysis of color infrared aerial photographs for the presence of vegetation stress is based upon the changes in infrared foliage reflec-tance that occur as a result of plant stress. A number of technical sources describe the theory and application of color infrared vegetation 4 9
analysis and were used as a guide for the photointerpretation in this plants under stress due to insect attack, disease or environnen-
] study.
tal conditions such as drought exhibit discoloration of their foliage on ; color infrared aerial film because of loss of reflectance. This decrease f of infrared mflectance occurs den normally highly reflective spongy ! leaf mesophy11 cells collapse becau'se of plant stress (Colwell,1956). l t Vegetation color differences can be used to make inferences about plant j vigor (Murtha,1982; Barrett and Curtis,1976). Healthy deciduous trees are highly reflective of infrared vegetation and appear as red and ; magenta in color infrared photographs. Evergreen pines and cedars 'at the , t site appear in shade of reddish gray. Stressed vegetation with leaf l yellowing apparent in normal spectral, color photography, appears in she. des of mouve, blue-grey, yellow and dite in color infrared photography. l t When vegetation is dead and dry it reflects as yellow and tan on color l infrared photography.
~
Using these differential reflectances as signature guides, examina-I tion of photographs was performed with simple hand lens magnification. Trees dich were possibly in stressed condition were morted on pho- l tographic prints for subsequent ground truthing. ( i 2.1.3 Ground Truthine Ground truthing of stressed vegetation us a process of actually locating at the Callaway site (with the aid of aerial photographs and r topographics) maps), potentially stressed trees recorded on aerf al pho- l tograph prints. The condition of these trees and the assessment made O , I i e
during phytopathological investigations were' then correlated with the - infrared photographic signature in order to achieve identification of stressed trees. Ground truthing took place from 20 August to 23 August l 1984. : 2.1.4 Veestation Manoine After photointerpretation and ground truthing, the locations of stressed or dying trees were plotted on a map of the Callaway Plant site at a scale of 1" = 2,000' (Figure 1). In areas of isolated tree damage .
. l 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 represented as shaded damage zones on the vegetation map. A considerable number of these trees that were plotted on the site vegetation map were inspected for photointerpretation ground truth , correlation and phytopathological appraisal. ! 2.1.5 Phytonatholoaical Investinations Individual trees that were located at the Callaway site from aerial photograph plotting were appraised by plant pathologists Barbara S. Lucas and Richard D. Skorepa of Growise Agricultural Consulting, Columbia, Missouri. The purpose of this appraisal was to provide diagnoses of the l I causes of vegetative stress found on specimens at the study site. The l causes of plant stress were to be separated into three major categories (
- 1) environmental, 2) disease, and 3) insect. Plant species very in their tolerance of, or sensitivity to, adverse conditions brwght 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.cate-
] gories of causes mentioned above. 6 i

Disease is a coadition in plant s brought about as a result of - M invasion of plaqt tissues by other living microorganisms. Primary 1 diseases, suck as. Oak wilt and Dutch Dm disease (DED), are caused by . microorganisms that can invade healthy plant tisues. These orpnisms k consume plant-supplied water and nutrient reserve: for their own growth, j therhy creating a stress on the plant. Secondary diseases, such as Maple declir.c', a e caused by ' disease complexes' which usually occur on plants 1 which have already been stressed from other auses.

3.1 RESULTS AND DISCUSSION O 3.1.1 Photointerpretation and Ground Truthing 5 Analysis of color infrared aerial photographs indicated that the vast majority of deciduous trees at the Callaway Plant site were in good a 9 health as indicated by their intense magenta reflectance. Certain deci-duous trees observed across the study site displayed somewhat lighter ; magenta or pink coloration or a light fringed appearance in infrared j
-i aerial photography. Ground truthing revealed these trees to be species 4 I
such as sycamore (Platanus occidentalis), persimmon (Diospyros virginiana) ard mulberry (Morus rubra) which were in good health. Such k trees possess a somewhat different infrared color signature than the deep magenta of the oaks and hickories which are dominant at the Callaway y site. Deciduous trees that showed signs of stress reflected in shades of E light pinkish mauve, grey and tan on infrared photography. Seventy-one h deciduous trees were plotted as individual stressed or dying trees on the site vegetation map (Figure 1). The distribution of these trees showed a no apparent pattern. Ground truthing and phytopathological examination 5 revealed that a variety of stress factors (detailed in Section 3.2, were I affecting these trees. In the southern portion of the study site several ; areas with relatively high densities of stressed or dying deciduous trees 2 were observed on the aerial photographs. These trees displayed yellowish 2 tan infrared reflectance and were recorded as six tree damage zones on
]
the site vegetation map. Field inspection revealed that these zones were 5 l l subject to forest management practices carried out by the Mi ssouri - l Department of Conservation in which less robust tree specimens were e l 4 l girdled by chain saw cutting. The culled dead and dying trees appeared j

as stressed aggregations on infrared aerial photography. l l O i. 11 d s M l -
s i 1 Healthy eastern redcedar (Juniperus virginiana) and pl antation 7 3 Q grown white pine (Pinus strobus), both evergreen species, displayed red-dish gray coloration in infrared photography. The only stressed indivi-duals that were apparent on aerial photographs were two white pine - specimens located in a cultivated stand just northwest of the complex of ( power plant buildings. This stand of white pine was in fairly good con-dition but with some lower branch dieback, perhaps due to crowding and ] sunlight shading. The two stressed pines displayed tan infrared reflec- E tance. Across the study site eastern redcedars were in good condition k _ with the only apparent damage being scattered broken branches caused by R winter icing. ] 3.1.2 phytopathological Investigations Oak wilt, a vascular disease caused by the fungus Ceratocystis h fagacearum was diagnosed as the cause of stress in 15 oak specimens. Fourteen of these trees were in the red oak group - red (Quercus rubra), or black (Quercus velutina), and one was a white oak (Quercus alba). - Diagnoses were based on symptom expression in the field. Symptom develp- == ment begins in the upper crown of infected trees. Leaves exhibit margi-nal scorching, a moisture stress symptom, and often fall from the tree. Leaf scorch symptoms develop because the fungus multiplies in the vascu- j lar system, effectively blocking the uptake of water. The disease deve- 2 ' lopes rapidly in the red oak group, spreading throughout the entire tree. - Infected trees in this group are often killed in a single season. 5 E Jisease development in white oaks is much slower. Symptom expression is J asually confined to a few branches each year. White oaks decline over a 3 O s 12 y -
*d "i
period of several years. . A black. discoloration of the outer - sapwood, indicative of a vascular disease, was observed in the infected white oak. Culture tests for oak wilt fungus proved negative for the presence of C., fagacearum. Although the oak wilt fungus was not recovered in culture, it is believed that this fungus is the cause of mortality in . many or ..e oaks that were examined. Low percentage recovery of E faga-cearum from o6k wilt-infected trees has been associated with high summer-temperatures and low rainfall (Bretz and Morison,1953;- Hauston et al ., 1965; Tainter and Gubler,1973). f Once a tree dies, the fungus produces geeltal mats underneath the ' outer bark. The veelial mats, or ' pressure pads', often split the bark, I exposing the pad surface upon which spores are produced. The spores have 4 a fruity odor dich is attractive to the sap . and bark-feeding beetles that vector the fungus to healthy trees. Pressure pads are fomed in the
. i late summer of death if adequate moisture is available. If moisture is limiting, pads may not fom until early spring if' at all (Boyce, 1957; Tainter and Gubler,1973). Invasion of tne oak-wilted trees by secondary ,
I disease organisms inhibits pad formation (Tainter and Gubler, 1973; . Shigo,1958). i . ! Dutch Elm disease (DED), caused by the fungus Ceratocystis ulmi, was identified as the stress factor on three slippery elm (Ulmus rubra) i l I trees. Diagnoses were based on visual symptoms: wilting , die-back of
. branches, and discoloration of the vascular system. DED is a vascular

' 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. They utilize the stump as an energy source for growth through the soil until a healthy root is encountered. These rots are therefore common in logged areas. Above-ground symptoms of root and butt rot are expressed as branch die-back and sparse, of f-color foliage. Fruiting bodies v .iocaps) of the causal fungi, when they occur, are usually fomed 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 wil t , the most frequently encountered cause of stress was mechanical injury and its after effects. Some mechanical wounds, sucii as frost cracks and broken branch stubs, are the first step in a discoloration and decay (heartrot) process. Although a succession of microorganisms are involved 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 O 14

not involved in .the transport of water and nutrients essential to the O . tree. Trees affected by aeartrot are structuraiiy unsound and sub;ect to repeated injury from winds, snow and ice accumulation, etc. Other wounds, such as a lightning strike that removes a layer or patches of bark along the length of the trunk, reduce the anount.of water and nutrient translocating tiss.ue available to meet the needs of the tree. In addition, a direct lightning strike usually damages the root f system substantialy. When the balance between roots and the shoots is destroyed, decline of th'e crown begins. We suspect that one case of chemical injury was encountered. Two walnuts to the west of ecology Plot 5 were exhibiting decline symptoms, i.e., sparse, small, pale foliage and branch die-back. The granular fonn of Tordon 10K had been selectively applied in the surrounding field for control of honey locust and multiflora rose. Several dead rose bushes were located within 10 feet of the affected walnuts. The two walnuts were growing in a slightly depressed area of the field that may have easily collected runoff water for short periods of time. Walnuts are very sensitive to this herbicide. Label restrictions on Tordon 10K spe-cifically state the high water solubility of the product and the tendency to run off in surface drainage water. The two walnuts were approximately
~
100 years old and were located on fairly deep soils, so there should not have - been any undue environmental or age-related stresses acting upon them. m==9 .---..-../---- 15

Three treeL species including hackberry (Celtis occidentalis)', maple (Acer saccharum) and American elm (Ulmus americana) exhibited symptoms of die-back and decline. No symptoms of cankers, mechanical injury, or root The die-back and decline symptoms varied with and butt . rot were found. the species but in general were: thinning crowns, small, pale foliage, branch die-back. While it is impossible to determine the exact cause of the decline, such symptoms are often indicative of a root problem. When the root system is not' functioning enough to meet the needs of above-ground parts, decline begins. Branch die-back is often the tree's attempt to reestablish the balance between roots and shoots. Some of the root problems that can lead to decline are: reduced oxygen in compacted soil, destruction of fine roots from extended drought, root rots, or site disturbances which physically damage roots. O In general, climatic conditions in the vicinity of the Callaway , j Plant from .May 1983 through August 1984 consisted of cold wi nters, 4 cooler, wetter springs and hotter, drier sunners when compared to 30-year averages (see Table 1). These conditions are generally not favorable for rapid and healthy plant development. Injury to plants by hot or cold temperature extremes may be by direct or indirect effects on plant tis-sues. Direct injury usually consists of some type of mechanical damage to cells and/or cell components. Examples of this type of injury are: 1
- 1) ice crystal formation intracellularly that can result in disruption of cell membranes, or 2) ice crystal fonnation intercellularly which, through greater negative water potentials of ice crystal surfaces, draws water out of cells, thus dehydrating protoplasm. Dehydration induces 16 t-

4 Indirect injury caused by temperature extremes.is generally related to metabolic disorders. In temperate regions the effects of high tem-
. perature are more commonly observed than injury from low temperatures.
High daily temperatures (above the maximum temperature for growth of a given -species) coupled with high night temperatures adversely affect , plant growth and development in two ways: 1) by decreasing total net photosynthate production per hour, and 2) by increasing total . net 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'. Edaphic factors also combine with site temperature and rainfall characteristics to affect vegetation health. The U.S. Department of . Agriculture Soil Conservation Service classifies the three most commonly
- observed soil types of the study site as Calwoods Gorin or Mexico ' silt 1
loam.- The subsoil of each type is a relatively deep (9 to 79 inches) ; silty clay or clay overlain by a shallow (3 to 7 inches) topsoil of silty l loam or silty clay loam. Permeability to water and available water capa-J city of these soils are the primary characteristics which affect plant growth. Each soil'has a large water holding capacity but also a low per-f meability to water and low available water capacity. With the ample pre-4 O 28 l
, l
cipitation wh.ich occurred in the springs of 1983 and 1984, these soils
-v O absorbed large quantities of water and because of their low penneability 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). Alternately, during the hot, dry sunsners of 1980,1983 and 1984, these soils began drying and, as they are composed of a high percentage of clay particles that tenaciously bond to water molecules, water as much less available to plants. In periods of high transpiration, plants growing in these types of soils generally cannot absorb and translocate sufficient amounts of water to continue nonnal or in some cases even sustainable growth rates. Thus they may become dehydrated, wilt and
- possibly die.
The evaluations of stressed vegetation are listed as groups that were in the vicinity of the ten UE permanent ecology plots. The final site listed was ,in the northwest portion of the plant property, not adja-l cent to any of the ecology plots. ; 19 4

y-4.1 . CONCLUSIONS O Most of the deciduous tree cover at the Callaway site is healthy, and reflects intense magenta on infrared aerial photography. Thosa" spe' ' ^ - - cimens that are stressed or dying are recognizable on color infrared pho-tography because of -their mauvish pink, grey or tan reflectance. The- , largest nunber of these stressed or dying trees occur in six tiree damage zones in which a forest management program is . carried out by the Misscuri Department of Conservation. In these areas the less robust tree speci-mens 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. = ~ 1o l Oak wilt was the natural stress occurring with the highest inci-dance. It is expected that oak wilt will continue to spread, both by ' S' : insect' vectors and natural root grafts. Rate of development will depend l i on environmental conditions. Local increase of oak wilt incidence is .
'I 1ower in the southern regions where mean monthly summer temperatures are j high (Tainter and Gubler,1973). .
1 i Climatic conditions from May 1983 through August 1984 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 adaphic factors it is expected that some mortality and decline due to moisture t I stress would be evident next spring. 36

1.0 INTRODUCTION
- In accordance with Appendix B, Section 5.4.1 of the Callaway Plant Operating License, the following report was prepared by Union Electric on all changes in plant design or operation, test and experiments made in accordance with Section 3.1 of Appendix B which involved a potentially significant unreviewed environmental question. This report covers all plant modifications that were completed from issuance of the operating license through December 31, 1984.
During 1984 there was one plant modification 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 84-02-17 2.1.1 Description of Change The installation of a box drain from the engineering safety features transformer pit to the site drainage system. This box drain allows the fire protection system deluge and hose stream overflow to drain from the engineering safety features transformer pit. (Construction completed 6/5/84) C-) Evaluation of Change 2.1.2 The construction of the box drain for the engineering safety features transformer pit did not result in a significant increase in any adverse environmental impact, since all measurable nonradiological environment effects are confined to the areas previously disturbed during site preparation and plant construction. In addition, the small amount of water from the fire protection system overflow will not cause a significant increase in any adverse environmental impact from the site drainage system. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License. O
