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 all the radiological cnvironmental monitoring conducted in the vicinity of the Callaway Plant during 1987 The comparison of the results for the radiological environmental monitoring conducted during 1987 to the preoperational data showed no unexpected or adverse ef fects f rom the operation of the Callaway Plant on the 1 1
environment.
4 The non-radiological monitoring conducted in the vicinity of the ;
i Callaway Plant during 1987 is contained in Section 2 of this report. The monitoring conducted during 1987 showed no evidence
! of effects of drif t from the cooling tower. The foliar disease found in the vegetation during 1987 could be directly attributed I to natural causes.
There were no plant modifications completed during 1987 with an l unreviewed environmental question as shown in Section 3 of this report.

Abstract The Radiological Environmental Monitoring Program .is an ongoing study conducted by Controls for Environmental Pollution, Inc. (CEP) for Union Electric Company (UEC),
Callaway Plant, Unit 1. This report is a summary of al' data obtained from samples i
collected by UEC personnel during 1987.
The monitoring program provides a comprehensive environmental analysis of radiological activity in the area surrounding the Callaway Plant Site. CEP analyzed the following types of samples: air particulate and radiciodine, ground water, surface water, milk, washload sediment, bedload sediment, bottom sediment, shoreline sediment, fish, vegetation, soil and direct radiation (TLD).
A statistical analysis and graphic presentation for all analytical results for samples collected during 1987 are included in this summary report. Possible trends and anomalous results, as interpreted by CEP are also discussed.
l.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 1987 for Union Electric Company, Callaway Piant, Unit 1.
In compliance with federal and state regulations and in its concern to maintain the quality of the local environment UEC began its radiological monitoring program in April,1982. j l
The objectives of the radiological environmental monitoring program are as follows:
i
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2)
I to monitor potential critical pathways of radioeffluent to man; 3) to determine 1
radiological impact on the environment caused by the operation of the Callaway Plant. i l
A number of techniques are being used to distinguish Callaway Plant effects from ;
other sources during the operational phase, ir.cluding application of established background levels. Operational radiation levels measured in the vicinity of the l 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. Tne plant consists of a 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1934.

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 area. Prior to this time, all analyses were performed by Radiation Management Company. i UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected weret milk, surface wa'.er, groundwater, shoreline sediment, bottom sediment, bedload sediment, washload sediment, soil, fish, vegetation, airborne particulates, airborne radiolodine and direct radiation (TLD).
Information regarding sample preparation and analytical methods, instrumentation, detection limits, etc. used by CEP may be found in the First Quarterly Report for p 1937.

3.0 Data Interpretations and Conclusions i
This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period.
l A variety of radionuclides, both naturally occuring and man-made, were detected in 1
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 th Callaway Plant were consistent with previously accumulated environmental data. -
l i
For this reporting period there was no reportable levels of radioactivity as a result of plant effluents, or analysis in which the detectisn limit was not achievable, j
i l
I
3.1 Airborne Particulates and Radiolodine Airborne particulate samples were collected from five monitoring stations. All of the air particulate samples were analyzed for Gross Beta activity. Gamma Spectrometry, Strontium-89 and Strontium-90 analyses were performed an quarterly composites from each station. The airborne particulate stations were also sites for airborne radioiodine.
The range and 1987 annual mean Gross Beta activity at each of the sarnpling locations follows. Measurements are in pCi/m3, Collection 1987 j Location _

Graphic presentations of the Weekly Gross Beta activities for each collection location are presented in Figures ! through 5. Invalid samples are those with anomolous Gross Beta activity due to air sampler malfunction (i.e. hour meter malfunction, sampler malfunction, etc.) or other circumstances which may have compromised the sample integrity.
Figure 6 presents the Mean Weekly Gross Beta activity for all collection locations. The lowest Mean Weekly Gross Beta activity (0.009 0.003 pC1/m3) was observed from 05/21/37-05/23/37 while the weeks exhibiting the highest activity were 07/30/87-03/06/87 (0.0351 0.005 pCl/m3 ) and 10/29/87-11/05/37 (0.03510.006 pC1/rn3 ).
I b Mean Quarterly. Gross Beta activities were as' follows:
DCl/m3 l January - March 1987 0.020 1 0.006 April - June 1987 0.016 1 0006 'i l July - September 1987 0.023 1 0.009 October - December 1987 0.023 1 0.006 Strontium-90 was detected in one of the quarterly composite samples during 1987. The first quarter composite for Site A8 indicated Strontium-90 activity of 0.00330.001 pCi/m3 l J
Gamma-emitting nuclides of interest detected in quarterly air particulate ;
composites were limited to Berylliui. 7. (See individual quarterly reports). 9 i
l Airborne radioiodine was detected in two samples during the first quarter of 1987. !

)
.I r i During the fourth quarter 1987, the air monitoring stations were taken out-of- '
1 service for a short period of time to allow replacement of sampling station l enclosure and sampling equipment. This replacement was required to improve station reliability and personnel safety. j l

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 polyethylere pouches were placed in plastic holders containing copper backing to shield out low energy radiation. The TLD's were placed at 52 l locations and exchanged monthly through June. Then beginning with the third 1
quarter the TLD's were exchanged quarterly.
{
Listed below are the mean readings in uR/hr for January through June and l mrem /Std. Qtr for the Third and Fourth Quarter, for all TLD's placed around the I Callaway Site. '

3.4 Surface Water -
Surface Water samples were collected from three locations on a monthly basis.
Samples were analyzed for Gross Alpha, Cross Beta, Tritium, Strontium-89, Strontium-90 and for Gamma-emitting nuclides. A summary of the Mean Gross -
Alpha and Gross Beta activities for Surface Water samples may be found in Table Ill.
Samples obtained from collection location 501 (4.8 mi SE, S4 feet upstream of discharge, North Bank) yielded a 1987 mean Gross Alpha activity of 3.51 0.9 pCi/l with a range from less than 2.0 pCl/l to 4.811.5 (collected 06/09/S7). The mean annual Gross Beta activity for 501 was calculated to be 7.91 3.5 pCi/l with a range of Gross Beta activity from less than 3.0 pCi/l to 16.210.9 pCi/l (collected 08/11/S7). The monthly Gross Alpha and Gross Beta results are shown in Figure ;
! 10. No Strontium-89 or Tritium activity was observed above detection limit in any of the Surface Water samples collected from location 501 during 1987. One 1
cample collected on 01/13/37 indicated a Strontium-90 activity of 2.410.9 pCl/1.
l Collection location SO2 (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 pCl/l to ;
l 4.711.5 pCi/l (collected 11/10/87). The 1987 mean Gross Alpha activity from this location was 3.910.7 pC1/l. An annual mean Gross Beta activity of 7.313.7 pCi/l was observed while the range of Gross Beta activity for this site was from less than 3.0 pCl/l to 16.0 11.0 pCi/l (co!!ected 10/13/87). Figure 11 shows the monthly Gross Alpha and Gross Beta results graphica!!y. All Surface Water
, samples collected from location 502 during 1987 were less than the detection i
limits for Tritium, Strontium-90 and Strontium-89 (500 pCl/1,1.0 pCl/l and 1.5 i
f pCl/l, respectively).

Figure 12 presents the monthly Gross Alpha and Gross Beta results for samples collected during 1937 from coller. tion location 503 (63 mi E, City of St. Louis Water Intake). A range of Gross Alpha activity from less than 2.0 pCi/l to 7.21.6 1 pCi/l (collected 08/21/S7) was observed in the samples collected from location 503. The 1987 mean Gr.,ss Alpha activity for samples from this location was 3.511.3 pCi/1. Results of Cross Beta analyses for Surface Water samples from Location 503 ranged from 3.01 0.6 pCi/l to 13.91 0.9 pCi/l collected 1
07/07/37. A 1937 mean Gross Beta activity of 7.9 14.3 pCi/l was observed for this site. No Strontium-90, Strontium-39 or Tritium were detected in any of the j i
Surface Water samples collected from this location during 1987.
J l
The 1937 mean Gross Alpha and Cross Beta activities for all Surface Water I samples were 3.6 1 1.2 pCi/l and 7.71 3.3 pCi/1. No gamma-emitting nuclides of ;
interest were detected in the 1937 Surface Water samples.
During 1937, the upstream surface water samples from January to September were daily grab samples composfted over the month. This was due to continuous maintenance problems with the upstream sampler. To reduce the out-of-service time for the upstream sampler, a redesign of the sampler was installed during September 1937.

3.6 Fish Five species of fish wen collected on a monthly basis from the same locatiors on the Missouri River as the sediment samples. Fish samples were not collected from location A and C during January due to adverse weather conditions and paucity of fish. Species of fish collected during 1987 include freshwater drum, bigmouth buff alo, srnallmouth buff ala, carp, goldeye, river carpsucker, shorthead redhorse, shortnose gar, longnose gar, gizzard shad, blue catfish, channel catfish, northern pike, flathead catfish, blue sucker and white crappie. Gross Alpha, Cross Beta, Strontium-89, Strontium-90 and Gamma Spectra! analyses were performed on all fish samples. All results are in terms of pCi/g (dry). The 1937 mean Gross Alpha and Cross Beta activities for each sampling location are summarized in Table V.
The monthly Cross Alpha activities in fish samples collected from Location A (4.9 mi SSE,0.6 river mile upstream of discharge, North Bank) ranged from less than 0.3 pCi/g to 1.210.2 pCi/g (Bigmouth Buffalo collected 07/09/37) with a 1987 mean Cross Alpha activity of 0.6 1 0.3 pCi/g. Cross Beta activities in these samples ranged from 1.31 0.1 pCi/g to S.410.2 pCl/g (Freshwater Drum collected 03/19/S7). The mean Gross Beta activity for 1937 Fish samples collected at ;
Location A was 6.0:1.4 pCi/g. Figure 22 is a chronological presentation of all Cross Alpha and Gross Beta activities for 1937. Strontium-90 and Streatium-39 were not detected in fish samples collected in 1987 from Location A. Cesium-137 was detected in one fish sample, Longnose Car co!!ected 06/25/37 indicate s )
activity of 0.1710.04 pCl/g. No other Gamma emitting nuc!! des were detected in the fish samples collected from Location A. l 0

Fish samples co!!ceted from Location C (5.1 mi SE,1.0_ river m!!e downstream of discharge, North Bank) had mean annual Gross Alpha and Gross Beta activities of 0.410.2 pCl/g and 6.011.6 pCl/g, respectively. Figure 23 !!!ustrates the monthly Gross Alpha and Gross Beta activities for fish collected from Location C. Cross Alpha levels in these samples ranged from less than 0.3 pCl/g to 0.310.2 pCl/g, a
while Gross Beta levels ranged from 2.210.1 pCl/g to S.610.2 pCl/g (Gizzard Shad collected 06/25/37 and Freshwater Drum co!!ected 12/03/37). No Strontium-39 or Strontium-90 was '"tected in any of the Fish from Collection Location C.
r Ceslum-137 was detected in the Gizzard Shad collected 06/25/37 (0.3010.15 oCl/g). No other gamma emitting nuc!! des of interest were detected in 1937 Location C Fish.
, Figure 24 graphically presents the monthly Gross Alpha and Gross Beta results
] for Fish samples collected from Location D. Gross Alpha activities ranged from
, less than 0.3 pCl/g to 0.310.2 pCl/g (River Carpsucker collected 02/04/37) with a mean Gross Alpha activity of 0.410.2 pC1/g for all fish collected from Location ,
D during 1937. Gross Beta ranged from 2.51 0.1 pCl/g to 3.5 10.2 pC1/g (Carp collected 07/07/37) with a 1937 mean of 5.3 1 1.4 pCl/g. No Strontium-39 or
- Strontium-90 activity was observed in any of the fish collected from this i
location. No gamma emitting isotopes of interest were detected in any of the j 1937 Location D Fish samples.

3.7 Milk During 1937, Milk samples were collected from two locations, the Green Farm (M-)), and the Schneider Farm. The Schneider Farm provided cow milk (M-5A) and goat milk (M-5B). Analyses for lodine-131, elemental Calcium, Strontium-39, Strontium-90 and Gamma emitting nuclides were performed on all milk samples. No cow milk samples were collected from the Schneider Farm during January and no gotst milk samples were collected from this farm during January, February, November and December, because the cows and goats were dry.
lodine-131 was detected in one milk sample collected during 1937. Activity of 1.010.5 pCi/l (collected 05/2S/37) was detected at the Green Farm.
Strontium-90 was detected in three milk samples during 1987. The Schneider cow milk of 03/08/37 indicated 2.41 0.7 pCl/l and the sample of 10/11/37 indicated 4.210.5 pCl/1. One goat milk from the Schneider farm indicated 3.210.9 pCl/l (10/12/37). No Strontium-89 was detected in the milk samples.
Elemental Calcium ranged from 740 mg/l to 1720 mg/1.
No gamma emitting nuclides of interest were detected in any of the milk samples collected during 1937, 9

In accordance with Technical Specification 3.12.2, the annual Land Use Census within a 5 mile radius of the Callaway Plant was performed during August,11987 by'the.
Union Electric Real Estate Department. Observations were made in each of the 16 meteorological sectors of the' nearest milking animals (cows and goats) , nearest residence, and the nearest _ garden of greater than 50m2 (500 ft2) producing broad leaf vegetation.- This census was completed by contacting the families identified in the 1986 census.and driving the roads within a 5 mile radius of the Callaway Plant noting the location of the above-mentioned items.
The results of the Land Use Census are presented ~in Table 1 thru 3 and discussed below. In the tables the radial direction and mileage from the'Callaway Plant containment are presented for each location. The radial direction is one of the 16 dif ferent . compass points. The mileage was estimated from map position for each location.

%Y Abstract Controls for Environmental Pollution, Inc (CEP) has conducted a radiological environmental monitoring program (REMP) for Union Electric Company (UEC), Callaway Plant, Unit 1, since May 5,1933. This quarterly report presents data for the months of 5ar uary, February and March 1987.
Evaluation of radiation levels in the environs around Union Electric Company's Callaway Plant entailed sampling at strategic points in various exposure pathways. The fo:!owing types of samples were collected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radiciodine, direct radiation (TI.D) and soil.
/~'N 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.
U
l.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during the first quarter of 1987 for Union Electric Company, Callaway Plant.
In compliance with federal and state regulations and in its concern to maintain the quality of the local environment UEC began its radiological monitoring program in April,1982.
The objectives of the radiological environmental monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations. In addition, results of the monitoring program help to evaluate sources of elevated leveis 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 one 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1984.
O i
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.
UEC personnel collected the samples and shipped them to CEP for analysis. The type of samples collected this quarter were: milk, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne 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.

3.0 Analytical Procedures The analytical procedures described below are those routinely used by CEP to analyze samples.
3.1 Airborne 3.1.1 Gross Alpha and Gross Beta The glass-fiber filter, type A/E (99 percent removal efficiency at I micron particulate), is placed into a two-inch stainless steel planchet and counted for Gross Alpha and Cross Beta radioactivity using an internal gas flow, ten channel low-level planchet counting system (Berthold LB770).
3.1.2 Gamma Spectrometry The filters are composited according to station and sealed in a small, plastic Marinelli beaker. The filters are then counted using either a Ge(Li) or intrinsic germanium detector which is coupled to a computer based, multi-channel analyzer (Nuclear Data). The resulting spectrum is then analyzed by the computer and specific nuclides, if present, identified and quantized.
3.1.3 Strontium-39 and Strontium-90 The composited filters are dissolved h, acid and brought to a known volume. Strontium carrier is added and the solution is evaporated to dryness. The resulting residue is taken up in dilute acid. Yttrium carrier is added and placed into ingrowth for 14 days. Af ter the ingrowth period has been established it is back extracted into an aqueous phase, precipitated as the oxalate, counted in a low background proportional counter (Berthold LB770), and calculated as Strontium-90 activity. The aqueous phase is evaporated to a low volume, precipitated with fuming nitric acid, redissolved in water, made basic with dilute cmmonium hydroxide and O
precipitated as the oxalate. The dried precipitate is counted in a low
['^
\ ;/
'" background proportional counter (Berthold LB770) and the Strontium-89 activity is determined by subtracting the previously measured Strontium-90 activity and its corresponding Yttrium-90 ingrowth from the measured gross Strontium activity.
3.1.4 lodine-131 3.1.4.1 Alkaline Leach Method The radiciodine is stripped off activated charcoal by reduction using concentrated ammonium hydroxide (NH40H) and hydrogen peroxide (H220 ). The charcoal is then filtered and the remaining solution is acidified with nitric acid (HNO3) and extracted with carbon tetrachloride (CCl4) to remove the lodine. It is then back !
extracted using 0.2% hydrazine solution, which supplies further l O '
purification and an aqueous media for precipitation. It is then (v) ;
precipitated with silver nitrate (AgNO3 ) and filtered on a tared j glass-fiber filter as silver iodide (Agi). The dried precipitate is weighed for recovery and counted for Iodine-131 in a thin window gas flow proportional counter (Berthold LB770) having a forty-one percent efficiency for Iodine-131 precipitated as silver iodide (Agi).
3.1.4.2 Gamma Spectrometry Method The charcoal canister is placed directly on an intrinsic germanium detector and lodine-131 activity determined using Method 3.1.2.
3.1.5 Direct Radiation Direct radiation measurements were taken using Thermoluminescent
( )
i /
Q/
Dosimeters (T L D's). Each settin ter consists of a Teflon wafer impregnated with twenty-five percent CaSO4 Dy phosphor. Dosimeters are annealed in an oven prior to use and are inserted into black polyethylene pouches. The CaSO4:Dy phosphor pouches are placed in rectangular holders which contain copper shielding to filter out low energy radiation.
Af ter exposure in the environment, the dosimeters are read in a Teledyne Isotopes model 3300 TLD reader.
3.2 Vegetation 3.2.1 Iodine-131 A suitable aliquot of wet (as received) sample is placed into a small, plastic Marinelli beaker and lodine-131 activity determined using Method 3.1.2.
3.2.2 Gross Alpha and Gross Beta A suitable aliquot of prepared sample is muffled, dissolved in dilute acid and transferred to a tared two-inch stainless steel planchet. The planchet is counted for Gross Alpha and Gross Beta activity using Method 3.1.1.
3.2.3 Gamma Spectrometry A suitable aliquot of prepared sample is placed into a small, plastic Marinelli beaker and specific nuclides, if present, identified and quantized using Method 3.1.2.
3.3 Milk 3.3.1 Iodine-131 Two liters of milk containing standardized lodine carrier are stirred with Amberlite IR A-400 anion exchange resin for one hour. The lodine is stripped from the resin with sodium perchlorate (NaClO4 ) acidified with nitric acid, precipitated with silver nitrate (AgNO3) and filtered on a tared glass-fiber filter. The dried precipitate is weighed for percent recovery and counted for lodine-131 in a thin window, gas flow, proportional counter
((Berthold LB770).

7.0 Quality Control Program CEP employs a multi-faceted Quality 'ontrol Program designed to maintain high performance of its laboratory. The overall objectives of the program are tot 1.) Verify that work procedures are adequate to meet specifications of UEC.
2.) Coordinate an in-house cuality 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, internal lab 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 qua'ity assurance practices.
8.0 Data Ir.terpretations 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). Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous and will be so noted in the report.

Mean weekly Cross Beta activities ranged from a low of 0.01520.001 pCi/m3 during the collection period of 03/19/37-03/26/S7 to a high of 0.023 0.009 pCi/m 3 during the collection period of 03/05/S7-03/12/37.
Strontium-90 was detected in one airborne particulate coposite; Site AS indicated Strontium-90 activity of 0.003:0.001 pCi/m 3. All of the other airborne particulate composite analyses for Strontium-S9 and Strontium-90 were less than the lower limit of detection (0.002 pCl/m3).
Gamma spectralanalysis of the site composites indicated the following activities:
Collection Location isotope identified pCi/m 3 Site A 1 Beryllium-7 0.01620.003 Site A7 Beryllium-7 0.013 0.003 Site AS Beryllium-7 0.023:0.002 Site A9 Beryllium-7 0.013 0.002 Site B3 Beryllium-7 0.009 0.002 No other gamma emitting isotopes of interest were detected in the quarterly site composites.
Results of the airborne radioiodine analyse:, may be found in Table V!!!. Two samples exhibited levels of lodine-131 greater than the detection limit of 0.006 pCi/m 3 Site B3, collected 01/30/S7 (0.009:0 003 pCi/m 3) and Site A9 (0.010 0,004) collected 03/12/S7.
Levels and fluctuations of activity in the air particulate and radiodine samples are consistent with the previously accumulated preoperational data.

3.2 Thermoluminescent Dosirnetry l 1
Thermoluminscent Dosimetry (TLD) was employed to determina direct radiation levels in and around the Callaway Site. Calcium Sulfate:Dy phosphor TLD chips in black polyethylene pouches were placed in plastic holders with areas 1 and 2 j containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch I copper shielding. The TLD's were placed at 52 locations and exchanged monthly.
Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosirneters were used to determine dosage eceived during shipment anc! were subtracted from the gross
,i readings obtained for each monitoring site.
Exposure levels for all monitoring locations during January, February, and March
( are consistent with background levels detected during the preoperational monitoring program.

8.3 Well Water Well water samples were collected monthly frorn three locations and analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, and gamma-emitting nuclides.
Table XII presents the results of the radiochemical analyses. Gross Alpha activity ranged from less than 2.0 pCi/l to 2.8 12.0 pCl/1. Gross Beta levels varied from less than 3.0 pCi/l to 14.7 30.8 pCi/1. The Gross Alpha and Gross Beta levels were consistent with the preoperational data.
Results for Tritium analysis were below the lower limit of detection (500 pCi/l) for all samples.
All sample results for Strontium 39 and Strontium 90 analysis were below the lower limits of detection (1.5 pCi/l and 1.0 pCi/l respectively).
Gamma spectrometry showed no detectable levels of isotopes of interest.
Results are summarized in Table XIII.

/' 8.4 Surface Water Surface water samples were collected from three locations on a monthly basis.
During the first quarter, the upstream composite water sampler was inoperable -
due to equipment failures. ' Therefore, daily grab samples were taken and' composited over the month. Samples were analyzed for Gross Alpha, Gross Beta,-
Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry. Results are summarized in Tables XIV and XV.
Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities from less than 2.0 pCi/l to 3.2 11.2 pCi/l and less than 3.0 pCi/l to 6.010.7 pCl/1, respectively. The positive Gross Alpha and Grcss Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and.are consistent with the preoperational data.
\ ,
All Tritium data from surface water samples were below the lower limit of detection (500 pCi/l).
Strontium-90 was detected in one sample, CA-SWA-sol co!!ected 01/13/87 with an activity of 2.4 10.9 pC1/l. No other Strontium-89 or Strontium 90 was detected in any of the surface water samples collected this quarter. ;
i Gamma Spectralanalysis of surface water samples showed no detectable activity from isotopes of interest.

8.5 Sediment Wash!oad, Bedload and Bottom Sediment samples were collected in March from three locations along the Missouri River. Samples were analyzed for Gross Alpha, Gross Beta, Strontium-90, Strontium-89, and by Gamma Spectrometry.
Results are summarized in Tables XVI thru XXI.
The following ranges of Gross Alpha and Cross Beta activities were observed in the washload, bedload and bottom sediments.
Gross Alpha Gross Beta Range Range Sample Type pCi/g pC1/g Washload 1.40.5-3.30.9 1 1 5.60.3-8.00.7 1 1 Bedload 1.20.3-2.00.8 1 1 3.30.2-4.20.6 1 1 Bottom 1.00.2-1.60.2 1 3 1.40.1-2.60.1 1 1 The highest activity of Gross Alpha (3.3 0.9 1 pCi/g) was seen in the Washload sediment at sample location D (59.5 river miles downstream of discharge south bank). The highest activity of Gross Beta (3.010.7 pCi/g) was seen in the Washload sediment at sample location C (1.0 river miles downstream of discharge north bank).
No Strontium-89 or Strontium-90 was detected in the washload, bedload, or bottom sediments collected during the first quarter 1937.

TN 8.6 Fish Due to adverse river conditions no fish samples were collected from locations A and C during January. Five (3) species of fish were collected at location D during January and from each of the three collection locations during the remainder of the quarter. Types of fish collected during this quarter were:
goldeye, freshwater drum, blue catfish, flathead catfish, black buffalo, carp, river carpsucker, channel catfish, shorthead redhorse, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectra! analysis were performed on all fish collected each month. Results are l presented in Tables XXII thru XXVII. The activity levels are consistent with the preoperational data. t Gross Alpha activity was detected in eight samples during this quarter. Gross l Beta activities ranged from a low of 1.8 1 0.1 pC1/g (sample CA-AQF-A, River f Carpsucker, collected 02/05/37) to a high of 7.3 20.2 pCi/g (sample CA-AQF-C, Grass Carp, collected 03/09/87). Gross Alpha and Gross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. Potassium-j 40). .

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

8.7 Milk Milk samples were collected from two locations, the Green Farm and the Schneider Farm. No samples were collected from Schneider Farm during January; the cows and goats were dry, and no goat milk sample was collected during February for the same reason. The Green Farm supplies cow's milk while the Schneider Farm provides both cow's milk and goat's milk. Analyses for Iodine-13 l, Elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVlli and XXIX present results of these analyses.
No lodine-131 was detected in the milk samples during this period.
e milk sample from Schneider Farm (MSA) collected 03/08/37, indicated Strontium-90 activity of 2.4 1 0.7 pCi/1. No Strontium-39 was detected in this sample. All of the other milk samples collected during the first quarter were below the lower limit of detection of 2.0 pCl/l for St.entium-39 and 1.0 pCi/l for Strontium-90.
No gamma-emitting isotopes of interest were detected in any of the milk samples.

) Isotopic Detection Limits and Activity Determinations Making a reasonable estimate of the limits 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 r.ot a fixed value but that a series of replicates would be normally distributed. The desired net activity is thus the difference between the gross sample activity and background activity distributions.
The interpretation of this difference becomes a problem if the two distributians intersect as indicated in the diagram.
Background Gross b

If a sufficient number of replicate analyses are run, it is to be expected that the results would fall in normal Gaussian distribution. Standard statistics allow an estimate of the probability of any particular deviation from the mean value, it is common practice to report the mean one or two standard deviations as the final result, in routine analysis such replication is not carried out, and it is not possible to report a Gaussian standard deviation 1 one or two Poisson standard deviations. The reported values are then considered to give some indication of the range in which the true value might be expected to occur.
The simplest possible case to consider would be one where the background is negligible and the sample activity is zero. It is sometimes not realized that if a series of counts is taken on such a system, half of the net values should be less than zero. Negative counts are not possible, of course. But when there is an appreciable background, the entire scale is raised.
The resulting situation: half of the sample counts on a zero activity sample would be less than background. This negative net count occurs frequently in low-level measurements, causing considerable concern. Actually, such results are to be expected.
Analytical detection limits are governed by a number of factors including:
- 1. $ ample Size
- 2. Counting Efficiency The fundamental quality in the measurement of a radioactive substance is the number of disintegrations per unit time. As with most physical measurements in analytical chemistry, it is seldom possible to make an absolute measurement of the disintegration rate, but rather, it is necessary to compare the sample with one or more standards. The standards determine the counter efficiency which may then be used to convert sample counts per minute (cpm) to disintegrations per minute (dpm).
- 3. Background Count Rate Any counter will show a certain counting rate without a sample in position.
This background counting rate comes from several sources: 1) natural environmental radiation from the surroundings, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background counting rate will depend on the amounts of these types of radiation and sensitivity of the counter to the radiation.
- 4. Background and Sample Counting Time The amcunt 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.

'~
i Decay measurements are useful in identifying certain short-lived isotopes. 1 The disintegration constant is one of the basic charac+ eristics of a specific radionuclide and is readily determined, if the half-life is sufficiently short. *
- 6. Chemical Recovery of the Analytical Procedures Most radlochemical analyses are carried out in such a way that losses occur during the separations.- These losses occur due to a large number of contaminants that may be present and interfere during chemical a
separations. Thus it is necessary to include a technique for estimating these losses in the development of the analytical procedure.

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 Environt ental 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 ( la t)
WHERE:
LLD = "A priori" lower limit of detection as defined above (as pCi per unit mass or volume).
sb = Standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute).
E = Counting efficiency (as counts per disintegration).
V = Sample size (in units of mass or volume).
2.22 = Number of disintegrations per minute per picocurie.
Y = Fractional radiochemical yield (when applicable).
A = Radioactive decay constant for the particular radioisotope, at = Elapsed time between sample collection (or erid of the sample collection period) and time of counting.
The value of sb used in the calculation of the LLD for a particular measurement system is based on the actual observed variance of the background counting rate, or, of the countmg rate of the blank sample, (as appropriate), rather than on an unverified theoretically predicated variance.
In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background included the typical contributions of other nuclides normally present in the samples.

G Abstract Controls for Environmental Pollution, Inc (CEP) has conducted a radiological environmental monitoring program (REMP) for Union Electric Company (UEC), Callaway Plant, Unit 1, since May 5,1983. This quarterly report presents data for the months of April, May and June 1937.
Evaluation of radiation levels in the environs around Union Electric Company's Callaway Plant entailed sampling at strategic points in various exposure pathways. The following types of samples were collected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washlead sediment, fish, airborne particulates, airborne radiolodine, direct radiation (TI.D) and soil.
@ Analytical results are presented and discussed information.along w Possible trends and anomalous results, as interpreted by Controls for Environmental Pollution, Inc., are discussed.

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during the second quarter of 1937 for Union Electric Company, Callaway Plant.
In compliance with federal and state regulations and in its concern to maintain the quality of the local environment UEC began its radiological monitoring program in April,1982.
The objectives of the radiological environmental monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiologicalimpact on the environment caused by the operation of the Callaway Plant.
O A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations, in addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.
The Callaway Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of one 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1934 O

l 7.0 Quality Control Program A summary of CEP's Quality Control Program is contained in the First Quarter 1987 Report (page 26). No changes in the Quality Control Program occured this quarter.
8.0 Data Interpretations and Conclusions O
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 statistical l analysis is made. Results which are outliers with respect to historical comparison of l
l previous data are considered out of baseline range or anomolous and will be so noted in l the report. l 0

(\ 's 3.1 Airborne Particulates and Radiolodine
]
Airborne particulate samples were collected at five (5) monitoring stations on a weekly basis from April 2,1987 through July 2,1937. The five airborne particulate stations were also collection sites for airborne radiciodine (see Table VI!!).
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.
Collection Location Minimum (pCi/m3) Maximum (pCi/m 3)
Site A1 0.010:0.001 0.032:0.003 Site A7 0.010 0.002 0.028 0.003 Site AS 0.03930.003 0.009:0.001 Site A9 0.009:0.002 0.025:0.003 Site B3 0.005:0.001 0.023:0,002 Table VII, Cross Beta in Airborne Particulates, shows that the Gross Beta 1
activity ranged from a minimum at Site B3 of 0.005:0.001 pC1/m3, collected I 05/21/37-05/23/87 to a maximum of 0.039 0.003 pCi/m3 at Site A8 during the collection period of 06/04/37-06/12/87.
The highest mean Gross Beta activity during the report period was observed at Site A3 with a mean activity d 0.01910.007 pCi/.a3 p
\
m e R ?&' .2 . a *%2
Mean weekly Gross Beta activities ranged from a low of 0.009 0.003 pC1/m3 during the collection period of 05/21/37-05/23/S7 to a high of 0.03010.006 pCi/m3 during the collection period of 06/04/37-06/11/87.
All of the airborne particulate composite analyses for Strontium-89 and Strontium-90 were less than the lower limit of detection (0.002 pCi/m3).
Gamma spectra! analysis of the site composites indicated the following activities:
Collection Location isotope identified pCi/m3 Site Al Beryllium-7 0.03310.004 Site A7 Beryllium-7 0.04110.003 Site A3 Beryllium-7 0.01110.002 Site A9 Beryllium-7 0.01610.003 Site B3 Beryllium-7 0.01510.002 No other gamma emitting isotopes of interest were detected in the quarterly site composites.
Results of the airborne radioiodine analyses may be found in Table Vill. No lodine-131 activity above the lower limit of detection (0.006 pCi/m 3) was detected this quarter.
Levels and fluctuations of activity in the air particulate and radioiodine samples are consistent with the previously accumulated preoperational data.

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 with areas 1 and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shielding. The TLD's were placed at $2 locations and exchanged monthly.
Data appearing in Tables IX thru XI are the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to determine dosage received during shipment and were subtracted from the gross readings obtained for each monitoring site.
Exposure levels for all mon;toring locations during April and May are consistent
)
(V with background levels detected during the preoperational monitoring program and with level; seen during previous quarters.
Half of the June TLD's and the transit control TLD had slightly higher than normal exposure levels. We have concluded that this excess exposure resulted from an unidentified radiation source during transit. Evidence to support this conclusion includes the fact that a review of the site TLD locations showed the exposed TLD's were located randomly around the plant site which would not be indicative of a plant related exposure. In addition, the Union Electric Company comparison TLD's that were placed in the fleid with the CEP TLD's did not show an increase in radiation exposure for the same time period.

8.3 Well Water Well water samples were collected monthly from three locations and analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-89, Strontium-90, and gamma-emitting nuclides.
Table XII presents the results of the radiochemical analyses. Gross Alpha activity ranged from less than 2.0 pCi/l to 5.61.6 1 pC1/l. Gross Beta levels varied from less than 3.0 pCi/l to 12.3 20.8 pCi/1. The Gross Alpha and Gross Beta levels were consistent with the preoperational data.
Resuits for Tritium analysis were below the lower limit of detection (500 pC1/l) for all samples.
All sample results for Strontium 89 and Strontium 90 analysis were below the t
lower limits of detection (1.5 pCi/l and 1.0 pC1/1 respectively),
Gamma spectrometry showed no detectable levels of isotopes of interest.
Results are summarized in Table XIII.

Surface water samples were collected from three locations on a monthly basis.
During the second quarter, the upstream composite water sampler was ,
inoperable due to equipment failures. Therefore, daily grab samples were taken and composited over the month. Samples were analyzed for Gross Alpha, Gross .l Beta, Tritium, Strontium-90, Strontium-89, and by Gamma . Spectrometry. '
Results are summarized in Tables XIV and XV.
1 Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities from less than 2.0 pCl/l to 4.811.4 pCi/l and 3.320.6 pCl/l to 12.010.7 ,
pCi/1, respectively. The positive Gross Alpha and Gross Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and are consistent with the preoperational data. !
\
All Tritium data from surface water samples were below the lower limit of detection (500 pCi/l).
l No Strontium-89 or Strontium-90 was detected in any of the surface water l samples collected this quarter.

8.5 Sediment Washload, Bedload and Bottom Sediment samples were collected in May from three locations along the Missouri River. Samples were analyzed for Gross Alpha, Gross Beta, Strontium-90, Strontium-89, and by Gamma Spectrometry.
Results are summarized in Tables XVI thru XXI.
The following ranges of Gross Alpha and Gross Beta activities were observed in the washload, bedload and bottom sediments.
Gross Alpha Gross Beta Range Range Sample Type pCi/g pCitg Washtoad 1.00.2-3.10.8 1 1 4.30.1-9.30.5 1 1 Bedload 0.70.2-0.90.2 1 1 1.90.1-3.30.1 1 1 Bottom 1.00.2-1.60.2 1 1 1.30.1-1.60.1 1
The highest activity of Gross Alpha (3.10.8 1 pCi/g) was seen in the Washload sediment at sample location D (59.5 river miles downstream of discharge south bank). The highest activity of Gross Beta (9.310.5 pCi/g) was seen in the Washload sediment at sample location D (59.5 river miles downstream of discharge south bank).
No Strontium-89 or Strontium-90 was detected in the washload, bedload, or bottom sediments collected during the second quarter of 1987.

8.6 Fish Fish were collected during the quarter from three collection locations. Types of fish collected during this quarter were: goldeye, freshwater drum, blue sucker, flathead catfish, shortnose gar, carp, longnose gar, northern pike, bigmouth buffalo, river carpsucker, channel catfish, shorthead redhorse, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-89 and Gamma Spectralanalysis were performed on all fish collected each month.
Results are presented in Tables XXII thru XXVII. The activity levels are consistent with the preoperational data.
Gross Alpha activity was detected in seventeen samples during this quarter and ranged from less than 0.3 pCi/g to 0.81 0.2 pCi/g. Gross Beta activities ranged from a low of 3.7 0.11 pCi/g (sample CA-AQF-D, flathead catfish collected 06/19/87) to a high of 8.610.2 pCi/g (sample CA-AQF-C, gizzard shad, collected 06/25/87). Gross Alpha and Gross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. Potassium-40).
All fish data for Strontium-90 and Strontium-89 were below the lower limits of detection of 0.20 pCi/g and 0.30 pCi/g, respectively.
Results of Gamma Spectralanalysis may be found in Tables XXIll, XXV, and XXVil.

8.7 Milk Milk samples were collected from two locations, the Green Farm and the Schneider Farm. The Green Farm supplies cow's milk while the Schneider Farm provides both cow's milk and goat's milk. Analyses for lodine-131, elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVI!! and XXIX present results of these analyses.
Iodine-131 was detected in one milk sample (1,020.5 pCi/1) from the Green Farm (M-1) collected 05/28/87. No Iodine-131 was detected in the other milk samples during this period.
All of the milk samples collected during the second quarter were below the lower
/ \
i i limit of detection of 2.0 pCi/l for Strontium-89 and 1.0 pCi/l for Strontium-90.
xJ No ge nma-emitting isotopes of interest were detected in any of the milk samples.

8.8 Vegetation Vegetation samples were collected from three (3) sampling locations during the second quarter of 1987. Vegetation samples consisted of spinach, lettuce, mustard greens, turnip greens and cabbage collected from the Beazley, Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha, Gross Beta, Iodine-131 and by Gamma Spectrometry. Results are presented in Tables XXX and XXXI.
Gross Alpha activity ranged from less than lower limit of detection (0.3 pCi/g) to a high of 2.610.3 pCi/g at the Becker Farm (CA-FPL-V6, Lettuce) collected on 06/15/87. These Gross Alpha activities are consistent with the levels found during monitoring in previous years.
Gross Beta activity observed in the vegetation samples ranged from 7.410.2 pCi/g to 27.410.3 pCi/g.
No gamma emitting nuclides of interest were detected in the vegetation samples collected during the second quarter of 1937.

1.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Prograrn (REMP) conducted during the third quarter of 1987 for Union Electric Company, Callaway Plant.
In compliance with federal and state regulations and in its concern to maintain the quality of the local environment UEC began its radiological monitoring program in April,1982.
The objectives of the radiological environmental monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiological impact on the environment caused by the operation of the Callaway Plant.
A number of techniques are being used to distinguish Callaway Plant effects from O
other sources during the operational phase, including application of established background levels. Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations. In addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric f allout 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 one 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1904 2-O I

No changes in the Quality Control Prograrn occurred this quarter.
S.0 Data Interpretations and Conclusions O
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 statistical evaluation. Results which do not compare with the historical range are recalculated fer 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 statistical analysis is made. Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous and will be so noted in the report.

{- 8.1 Airborne Particulates and.Radiolodine Airborne particulate samples were collected at five (5) monitoring stations on a weekly basis from July 2,1987, through October 1,1987. The five airborne particulate stations were also co!!ection sites for airborne radiolodine (see Table Vill).
All of the air particulate samples were analyzed for Gross Beta activity.
Gamma Spectrometry, Strontium-90 and Strontium-89 analyses were performed on quarterly composites from each station.
The range of Gross Beta activity at each of the sampling locations follows.
Collection Location Minimum (pCl/m3) Maximum (pCl/m3)
Site Al 0.01110.002 0.03210.002 Site A7 0.01610.002 0.04810.002 Site A8 0.007 0,002 0.03210.002 Site A9 0.01310.002 0.02710.003 Site B3 0.01120.002 0.04420.003 Table VII, Gross Beta in Airborne Particulates, shows that the Gross Beta activity ranged from a minimum at Site A8 of 0.007 0.002 1 pC1/m3, co!!ected 07/09/87-07/16/87 to a maximum of 0.04810.002 pC1/m3 at Site A7 during the collection period of 09/03/87-09/10/87.
4 The highest mean Gross Beth activity during the report period was observed at Site A7 with a mean activity of 0.03210.010 pC!!m3 .

)
Mean weekly Gross Beta activities ranged from a low of 0.01610.006 pCi/m3 during the collection period of 07/09/87-07/16/87 to a high of 0.03510.005 pC1/m3during the collection period of 07/30/87-08/06/87.
All of the airborne particulate composite analyses for Strontium-89 and Strontium-90 were less than the lower limit of detection (0.002 pCi/m3).
Gamma spectralanalysis of the site composites indicated the following activities:
Collection Location Isotope identified pCi/m3 Site Al Beryllium-7 0.01810.002 Site A7 Beryllium-7 0.02810.003 Site AS Beryllium-7 0.06610.008 Site A9 Beryllium-7 0.04310.011 Site B3 Bery!!!um-7 0.03020.003 No other gamma emitting isotopes of interest were detected in the quarterly site composites.
Results of the cirborne radioiodine analyses may be found in Table VIII. No lodine-131 activity above the lower limit of detection (0.006 pCi/m3) was detected this quarter.
Levels and fluctuations of activity in the air particulate and radiciodine samples are consistent with the previously accumulated preoperational data.

r] 8.2 Thermoluminescent Dosimetry
\v' 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 with areas 1 and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch copper shleiding. The TLD's were placed at 32 locations and exchanged quarterly. (Beginning with the third quarter, 1987, the TLD's are being exchanged quarterly instead of monthly as they have been in the past.)
Data appearing in Table IX is 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. Net exposures were obtained by normalizing (m')
\s' the total exposures to a 90-day quarter (standard quarter).
Exposure levels for all monitoring locations during the third quarter,1937, are consistent with background levels detected during the preoperational monitoring program and with levels seen during previous quarters.

8.4 Surface Water Surface water samples were collected from three locations on a monthly basis.
During the third quarter, the upstream composite water sampler was inoperable at various times due to equipment failures. Therefore, daily grab samples were taken and composited over the month. Samples were analyzed for Gross Alpha, Gross Beta, Tritium, Strontium-90, Strontium-89, and by Gamma Spectrometry.
Results are summarized in Tables XII and XIII.
Gross Alpha and Gross Beta analyses of surface water samples showed a range of activities from less than 2.0 pCl/l to 4.71.41 pCl/l and less than 3.0 pCi/l to 18.91 0.9 pCi/1, respectively. The positive Gross Alpha and Gross Beta activities can be attributed to naturally occurring isotopes, such as Potassium-40, and are.
consistent with the preoperational data.

8.6 Fish A Fish were collected during the quarter from three collection locations. Types o'f fish collected during this quarter were: freshwater drum, blue sucker, flathead catfish, shortnose gar, carp, longnose gar, bigmouth buffalo, river carpsucker, channel catfish, blue catfish, smallmouth buffalo, and gizzard shad. Gross Alpha, Gross Beta, Strc ntium-90, Strontium-89 and Gamma Spectra! analysis were performed on all fish collected each month. Results are presented in Tables XX thru XXV. The activity levels are consistent with the preoperational data.
Gross Alpha activity during this quarter ranged from less than 0.3 pCi/g to 1.21 0.2 pCi/g. Gross Beta activities ranged from a low of 2.3 1 0.1 pCi/g (sample CA-AQF-C, shortnose gar collected 07/09/87) to a high of 8.5 10.2 pCi/g (sample CA-AQF-D, carp, collected 07/07/87). Gross. Alpha and Gross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. I Potassium-40). l l
All fish data for Strontium-90 and Strontium-89 were below the lower limits of detection of 0.20 pC1/g and 0.30 pCi/g, respectively.
Results of Gamma Spectralanalysis may be found in Tables XXI, XXill, and XXV.

8.7 Milk Milk samples were collected from two locations, the Green Farm and the Schneider Farm. The Green Farm supplies cow's milk while the Schneider Farm provides both cow's milk and goat's milk. Analyses for Iodine-131, elemental Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were performed on all milk samples. Tables XXVI and XXVII present results of these analyses.
No lodine-131 above the lower limit of detection (0.5 pCi/1) was detected in the milk samples during this period.
All of the milk samples collected during the third quarter were below the lower limit of detection of 2.0 pCi/l for Strontium-89 and 1.0 pCi/l for Strontium 90.
No gamma-emitting isotopes of interest were detected in any of the milk Ol samples.

l 8.8 Vegetation Vegetation samples were collected from three (3) sampling locations during the L
third quarter of 1987. Vegetation samples consisted of lettuce, mustard greens, turnip greens and cabbage collected from the Beazley, Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha, Gross Beta, Iodine-131 and by Gamma Spectrometry. Results are presented in Tables XXVIII and XXIX. :
Gross Alpha activity ranged from less than lower limit of detection (0.3 pCi/g) to a high of 0.8 10.2 pCi/g at the Beazley Farm (CA-FPL-V3, Mustard Greens) collected on 07/21/87. These Gross Alpha activities are consistent with the l
levels found during monitoring in previous years.
l Gross Beta activity observed in the vegetation samples ranged from 1.10.1 2 pCi/g to 22.210.3 pCi/g. j Wo gamma emitting nuclides of interest were detected in the vegetation samples collected during the third quarter of 1987.

( h Abstract Controls for Environmental Pollution, Inc (CEP) has conducted a radiological environmental monitoring program (REMP) for Union Electric Company (UEC), Callaway Plant, Unit 1, since May 5,1933. This quarterly report presents data for the months of October, November and December 1937.
Evaluation of radiation levels in the environs around Union Electric Company's Callaway Plant entailed sampling at strategic points in various exposure pathways. The following types of samples were collected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, washload sediment, fish, airborne particulates, airborne radioiodine, direct radiation (TLD) and soil, f
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.
O V
l.0 Introduction This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during the fourth quarter of 1937 for Union Electric Company, Callaway Plant.
In compliance with federal and state regulations and in its concern to maintain the quality of the local environment UEC began its radiological monitoring program in April,1982.
The objectives of the radiological environmental monitoring program are as follows:
- 1) to establish baseline radiation levels in the environs prior to reactor operations; 2) to monitor potential critical pathways of radioeffluent to man; 3) to determine radiological impact on the environment caused by the operation of the Callaway Plant.
A number of techniques are being used to distinguish Callaway Plant effects from other sources during the operational phase, including application of established background levels.
Operational radiation levels measured in the vicinity of the Callaway Plant are compared with the pre-operational measurements at each of the sampling locations, in addition, results of the monitoring program help to evaluate sources of elevated levels of radiation during reactor operation in the environment, e.g., atmospheric fallout or abnormal plant releases.
The Callaway Plant is located on a plateau approximately five miles north of the Missouri River in Callaway County, Missouri. The plant consists of one 1150 MWE pressurized water reactor, which achieved initial criticality on October 2,1984 9
^
/ 2.0 Description of the Monitoring Program i
Union Electric Company has contracted with Controls for Environmental Pollution, Inc., starting May,1933, to determine the radiation levels existing in and around the Callaway Plant area.
A summary of the Callaway Plant Monitoring Program is contained in the first quarter report,1937 (page 3) No changes in the monitoring program occurred during the third quarter,1987.
3.0 Analytical Procedures '
The analytical procedures routinely used by CEP to analyze sar.'ples are discussed in the First Quarter 1987 Report (pages 14 to 13). No new enalytical methods were used this quarter.
4.0 Sample Preparation Methods Sample preparation methods used by CEP are discussed in the First Quarter 1987 l Report (page 19). No new sample preparation methods were used this quarter.
5.0 Major Instrumentation Major analytical instrumentation used by CEP are discussed in the First Quarter 1937
)
Report (pages 20 to 21). No new instrumentation was used for sample analysis this quarter.
6.0 Isotopic Lower Limits of Detection and Activity Determinations I t
A discussion of the calculations used in determining lower limits of detection and ,
i activity by Controls for Environmental Pollution, Inc., is found in Appendix B, First l Quarter 1987 Report.
l
l Table 111 in the first quarter 1987 report gives the lower limits of detection for radiochemical and chemical analytical methods.
Table IV in the first quarter 1987 report gives the lower limits of detection for Gamma Spectrometry.
The sample counting times and the aliquot size used for lower limit of detection calculations and actual analyses are shown in Tables V and VI, in the first quarter 1987 report, respectively.
7.0 Quality Control Program A summary of CEP's Quality Control Program is contained in the First Quarter 1987 Report (page 26). No changes in the Quality Control Program occurred this quarter.
8.0 Data Interpretations and Conclusions O
1 i
This section addresses interpretations and conclusions regarding all types of samples analyzed during this report period.
Analysis anel review of data incorporates various techniques from historical comparison to statistical evaluation. Results which do not compare with the historical l 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 statistical analysis is made. Results which are outliers with respect to historical comparison of previous data are considered out of baseline range or anomolous and will be so noted in the report.

h 8.1 Airborne Particulates and Radiolodine G Airborne particulate samples were collected at five (5) monitoring stations on a weekly basis from October 1, -1987, through December 30, 1987. The five airborne particulate stations were also collection sites for alrkorne radiolodine (see Table Vill).
All of the air particulate samples were analyzed for Gross Beta activity.
Gamma Spectrometry, Strontium-90 and Strontium-89 analyses were performed on quarterly composites from each station.-
The range of Gross Beta activity at each of the sampling locations follow'.
Collection Location Minimum (pCl/m3) Maximum (pCi/m3)
Site A1 0.01210.001 0.03310.002 Site /.7 0.01310.002 0.03610.002 Site AS 0.01110.001 0.03110.002 Site A9 0.01520.002 0.03710.002 Site B3 0.01310.002 0.03910.002 '
Table Vil, Gross Beta in Airborne Particulates, shows that the Gross Beta activity ranged from a minimum at Site AS of 0.0111 0.001 pCl/m', collected 10/01/87-10/03/37 to a maximum of 0.0391 0.002 pCl/m3 at Site B3 during the '
t co!!ection period of 10/29/37-11/05/87.
The highest mean Gross Beta activity during the report period was observed at Sites A7 and A9 with mean activities of 0.02410.007 pC1/m3 and 0.02410.006 pCl/m3, respectively, i
Mean weekly Gross Beta activities ranged from a low of 0.0151 0.006 pCi/m3 during the collection period of 10/01/S7-10/03/37 to a high of 0.03510.006 pCi/m3 during the collection period of 10/29/37-11/05/S7.
All of .the airborne particulate composite analyses for Strontium-39 and Strontium-90 were less than the lower limit of detection (0.002 pC1/m3).
Gamma spectralanalysis of the site composites indicated the following activities:
Collection Location isotope Identified pCi/m3 Site Al Beryllium-7 0.07310.029 Site A7 Beryllium-7 0.09310.031 Site AS Beryllium-7 0.06210.025 Site A9 Beryllium-7 0.06210.039 Site B3 Beryllium-7 0.23010.120 No other gamma emitting isotopes of interest were detected in the quarterly site composites.
Results of the airborne radiciodine analyses may be found in Table Vill. No lodine-131 activity above the lower limit of detection (0.006 pCi/m3) was detected this quarter.
Levels and fluctuations of activity in the air particulate and radiciodine samples are consistent with the previously accumulated preoperational data.

1 8.2 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 with areas 1 and 2 containing 0.022 inch copper shielding and areas 3 and 4 containing 0.093 inch-copper shielding. The TLD's were placed at 52 locations and exchanged ;
1 i quarterly. (Beginning with the third quarter, 1987, the TLD's are being exchanged quarterly instead of monthly as they have been in the past.) '
i j
Data appearing in Table IX is the result of reading and averaging the four quadrants of each TLD chip. Transit control dosimeters were used to determine l
a dosage received during shipment and were subtracted from the gross readings
! i obtained for each monitoring site. Net exposures were obtained by normalizing ;
the total exposures to a 90-day quarter (standard quarter).
Exposure levels for all monitoring locations during the fourth quarter,1937, are ,
consistent with background levels detected during the preoperational monitoring program and with levels seen during previous quarters.

f 8.6 Fish Fish were collected during the quarter from three locations. Types of fish collected during this quarter were: freshwater drum, blue sucker, carp, longnose gar, bigmouth buffalo, river carpsucker, goldeye, shorthead redhorse, channel catfish, blue catfish and gizzard shad. Gross Alpha, Gross Beta, Strontium-90, Strontium-39 and Gamma Spectralanalysis were performed on all fish co!!ccted each month. Results are presented in Tables XX thru XXV. The activity levels are consistent with the preoperational data.
Gross Alpha activity during this quarter ranged from less than 0.3 pCi/g to 0.410.1 pCi/g. Gross Beta activities ranged from a low of 2.5 20.1 pCi/g (sample CA-AQF-D, channel catfish collected 11/03/37) to a high of S.610.2 pCi/g (sample CA-AQF-C, freshwater drum co!!ected 12/03/37). Gross Alpha and Cross Beta activities seen in fish samples can be attributed to naturally occurring isotopes (e.g. Potassium-40).
All fish data for Strontium-90 and Strontium-39 were below the lower limits of detection of 0.20 pCi/g and 0.30 pCi/g, respectively.
Results of Gamma Spectralanalysis may be found in Tables XXI, XXIII, and XXV.

' Milk samples were collected from twol locations, the Green Farm .and the.
Schneider Farm. The Green Farm supplies cow's milk while the Schneider Farm. '
provide; both cow's milk and . goat's milk. Analyses for Iodine-131, elemental .
. Calcium, Strontium-90, Strontium-89 and Gamma-emitting isotopes were f
performed on all milk samples. Tables XXVI and XXVII present results of these.
analyses.
No lodine-131 above the lower limit of detection (0.5 pCi/l) was' detected in th'e milk samples during this period.
Two milk samples indicated the presence of Strontium-90. The' cow's milk and ,
goat's milk collected on 10/11/87 from the Schneider Farm had activity of 4.210.5 pCi/l and 3.210.9 pCl/1, respectively.
All of the other milk samples collected during the fourth quarter were below the lower limit of detection of 2.0 pCl/l for Strontium-89 and 1.0 pCi/l for Strontium-90.
4 No gamma-emitting isotopes of Interest were detected in any of the milk samples.

8.3 Vegetation Vegetation samples were collected from two (2) sampling locations during the ,
}
fourth quarter of 1987. Vegetation samples consisted of lettuce, mustard greens, spinach, turnip greens and cabbage collected from the Becker and Meehan Farms. All vegetation samples were analyzed for Gross Alpha, Cross Beta, lodine-131 and by Gamma Spectrometry. Results are presented in Tables XXVill and XXIX.
Gross Alpha activity ranged from less than lower limit of detection (0.3 pCi/g) to a high of 0.310.2 pCi/g at the Meehan Farm (lettuce and turnip greens) collected on 10/21/87. These Gross Alpha activities are consistent with the levels found during monitoring in previous years.
Gross Beta activity observed in the vegetation samples ranged from 5.020.1 pCi/g to 24.020.3 pCi/g.
No gamma emitting nuclides of interest were detected in the vegetation samples collected during the fourth quarter of 1937.

EXECUTIVE
SUMMARY
d Environmental information on the condition of vegetation at the Callaway site during the third year of plant operation was developed through infrared aerial photography, photointerpretation and ground truthing of stressed vegetation, vegetation mapping and phytopathological diagnosis of stressed vegetation during August, 1987.
Ten 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 perfonned based upon the differential infrared reflectance characteristics of healthy versus stressed tree cover. The infrared photographic record was then verified with a ground truthing field inspection. On-site and laboratory phytopathological diagnoses were made for stressed vegetation identified from aerial pho-tography. A vegetation map was produced to show the location of stressed vegetation.
No evidence of the ef fects of drift from the cooling tower was found. Vegetation stress in the vicinity of the plant site was found to be caused by natural factors such as oak wilt, Dutch elm disease, root and butt rot and dieback due to unf avorable edaphic and meteorological conditions. No distributional pattern of these diseases was identified during the study. Therefore, the foliar dise,ase found in the Callaway vegetatic'1 during 1987 can be directly attributed to natural causes and not to operation of the Callaway cooling tower, iii

1.0 INTRODUCTION
l g 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. The goals of the program -
! are to establish a record of baseline and operational phase vegetation
! conditions at the Callaway Plant site using color infrared aerial pho- 1 tography, to document any naturally occurring vegetation strecs, and to l determine if any vegetation damage can be attributed to operation of the j ,
cooling tower. Interpretation of aerial photographs was used to prepare
) : this information. This was supplemented by ground truthing to assure l
i accurate interpretation of photographs and field phytopathological I~ assessment to identify the causes of any vegetation stress encountered.

1 Using these investigative methods, preoperational baseline environ- f
,, mental information on the condition of vegetation at the Callaway Plant l,
site was developed during July and August, 1984. Observations during the i
~
first and second years of plant operation were made during August,1985 !
I i and July and August,1986. During August,1987 monitoring was performed i i 1 l to assess the condition of vegetation during the third year of plant
- operation. The results of these four years of monitoring complement ,
other vegetation monitoring undertaken at the study site. Prior to the present program of infrared aerial photographic monitoring, classical i

N 2.1 Aerial photography ,
Aerial photography for this project was flown from 0936 to 1016 hours0.0118 days <br />0.282 hours <br />0.00168 weeks <br />3.86588e-4 months <br /> on 5 August 1987 by Walker and Associates, Inc. of Fenton, Missouri. No cloud cover was present. Atmospheric conditions were haze-and dust-free. Color infrared film was exposed in a Wild RC-8 precision
~ aerial mapping camera with 6 inch focal length lens. Ten one-hectare terrestrial study plots were photographed with 60 percent forward overlap at a scale of 1" = 250' . The residual lands of the plant site were pho- ;
l tographed with 60 percent fomard overlap and 30 percent side overlap at a scale of 1" = 1000' . Overlapping of photo frames is used to assure adequate coverage that avoids any visual distortio., or loss of infrared photograph brightness that may occur along the edges of an aerial pho-
,j tographic exposure. Duplicate sets of positive film transparencies and positive prints were produced in 9" by 9" fonnat. f l

. s 2.2 Photointerpretation i
Analysis of color infrared aerial photographs for the presence of t
vegetation stress is based upon the changes in infrared foliage reflec-
- {.
tance that occur as a - result of plant stress. A number of technical 4
sources describe the theory and application of color infrared vegetation :
- -- analysis and were used as a guide for the photointerpretation in this ,
t study. Plants under stress due to insect attack, disease or environmen- l I
.i tal conditions such as drought exhibit discoloration of their foliage on l color infrared film because of loss of reflectance. This decrease of infrared reflectance occurs when nonnally highly reflective spongy leaf l-- mesophyll cells collapse because of plant stress (Colwell, 1956). (
w Vegetation color differences can be used to make inferences about plant vigor (Murtha, 1982; Barrett and Curtis, 1976). Healthy deciduous trees l
] ".,
are highly reflective of infrared vegetation and appear as red and ]
l*
d magenta in color infrared photographs. Evergreen pines and cedars at the j site appear in shades of reddish gray. Stressed vegetation, with leaf ;
- i j . yellowing apparent in normal spectral color photography, appears in sha- l i
] .
des of mauve, blue-grey, yellow and white in color infrared photography. f When vegetation is dead and dry, it appears as yellow and tan on color ;

2.3 Ground Truthing Ground truthing of stressed vegetation was the process used to
[ locate (with the aid of aerial photographs and topographical maps) poten-
- tially stressed trees recorded on aerial photograph prints. The con-I dition of these trees and the assessment made during phytopathological l- investigations were then correlated with the infrared photographic signa-ture in order to identify stressed trees. Ground truthing took place on f1 29 and 30 August 1987.

1 2.4 Vegetation Macoing i 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). Individual stressed or dying trees were represented by an asterisk (*) on the vegetation map. A con-
~~
siderable number of the trees that were plotted on the site vegetation map were inspected for photointerpretation ground truth correlation and I i
- phytopathological appraisal. l i
t .
. 2.5 Phytocathological Investigations Individual trees that were located at the Callaway site from aerial l l I photograph plotting were appraised by plant pathologist Barbara S. Lucas of Columbi a, Missouri. The purpose of this appraisal was to provide
! diagnoses of the causes of vegetative stress found on specimens at the l study site. The causes of plant stresses were categorized as environmen- )
tal, disease, or insect. Plant species vary in their tolerance of, or l

sensitivity to, adverse conditions brought about by any of the above i categories. It is pertinent to note that stress symptoms in . plants, ,
4 especially trees, can be very similar among the categories of causes men-
.i i
. tioned above.
Freezing and thawing, drought, flooding, lightning damage, chemical E injury, mechanical injury, or high winds are all examples of environmen- [
tal conditions that can result in stressed plants. These conditions may
) ,
. cause outright death of plants or may stress them to a point where they 3 are unable to withstand invasion by secondary disease organisms or insect-m ,
f pests.
Disease is a condition in plants brought about as a result of inva-
.2 sion of plant tissues by other living microorganisms. Primary diseases, !
a
-' such as oak wilt and Dutch elm disease (OED), are caused by microorga- l l
nisms that can invade healthy plant tisues. These organisms consume
) plant-supplied water and nutrient reserves for their own growth, therby j creating a stress on the plant. Secondary diseases, such as maple
,2 decline, are caused by "disease complexes" that usually occur on plants I* that have already been stressed from other causes. Disease complexes are i generally caused by microorganisms that by thems el ves cannot invade i .
I
~
tissues of healthy plants. When plants are stressed, however, their nor- :
) i l
! mal resistance to invasion by insect and disease organisms is lowered. {
i - The disease-complex organisms then are able to invade plant tissues, causing further stress and/or death of the plant.

Insects may cause direct or indi rect damage to plants that may result in stress. Direct damage usually is-a result of feeding on plant parts such as leaves, back (cambial -layers), wood, or roots. Oviposition (egg-laying) is another type of. direct damage that can restrict the flow of water or nutrients in the plant. Insects may also cause indirect damage by serving as vectors of disease-causing organisms; insects feeding on viseased plants inadvertently carry spores of disease .orga-
, nisms to healthy plants.
The elements that were analyzed during diagnosis of stressed tree specimens were: history of forest management practices or herbicide application, site edaphic conditions, condition of surrounding vegeta-
,, tion, recent meteorological record, and inspection of tree leaves,
- branches, bark and roots. In addition to field observations, standard i culturing procedures using twigs and small branches wre carried out in j the laboratory in an attempt to recover the causal fungus in cases of suspected fungal infestation. Samples were plated on two culture media:
- 1) cak wilt agar (Nutrimigen base) and 2) acid potato-dextrose agar.
. These laboratory procedures were inconclusive in 1984 and were not repeated in 1985 or in 1986. In 1987, twig samples from two oak speci-
~
mens were again cultured in an attempt to isolate the causal fungus.

3.0 RESULTS AND O!SCUSSION l
1 6 3.1 photointerpretation and Ground-Truthing j i
j Analysis of color infrared aerial photographs -indicated that the l
vast majority of deciduous trees at the Callaway Plant site were in good ;
t Certain deci-health as indicated by their intense magenta reflectance. i duous trees observed across the study site displayed somewhat lighter ;
magenta or pink coloration or a light _ fringed appearance _ on infrared
~
1 I aerial photographs. Ground truthing revealed these trees to be spacies such as red maple (Acer rubrum), sycamore (Platanus occidentalis), per-simmon (Diospyros virginiana), cottonwood (populus _ deltoides) and i j ,, mulberry (Morus rubra) that were in good health. Such trees possess a ,
j .. somewhat different infrared color signature than the deep magenta of the i i -
oaks and hickortes that are dominant at the Callaway site. Deciduous
~~
trees that showed signs of stress reflected in shades of light pinkish ,
mauve, grey and tan on infrared photography. These deciduous trees were ,
~
plotted as individual stressed or dying trees on the site vegetation map i l
I ,, (Figure 1). The distribution of these trees showed no apparent pattern. l 4 Ground truthing and phytopathological examination revealed that a variety of stress factors (ddtailed in Section 3.2) were affecting these trees.
i
- Ouring previous years of vegetation monitoring, areas with relatively i high densities of stressed, dying or dead deciduous trees were observed
,, on the aerial photographs. These areas wer 4 recorded in past jears as tree damage zones on the site vegetation map. Fleid inspection revealed 1 ,

by the Missouri Department of Conservation in which less robust tree spe-cimens or undesired species were girdled by chain saw cutting. The l
culled dead and dying trees appeared as stressed aggregations on infrared 1 ..
aerial photography. In an area to the west of Vegetation Ecology Site 2, numerous trees appear as whitish, barren trunks on infrared aerial pho-s .
tography. These dead trees have been left standing on this site for some time and have been noted in the three previous annual reports on aerial
- , photographic vegetation monitoring at the Callaway site. This area is not mapped as a tree damage zone in this 1987 report since the observed j trees at this location have been dead for several years and the area is i
now in a process of regrowth / recovery. No other tree damage zones were
~
noted over the entire Callaway study site in 1987 vegetation monitoring.
i I. Healthy eastern redcedar (Juniperus _ virginiana) and plantation grown ;
1
) white pine (Pinus strobus), both evergreen species, displayed reddish gray coloration in infrared photography. The only stressed white pine that was apparent on aerial photographs was a single specimen located in a cultivated stand just northwest of the complex of power plant
., buildings. This stressed pine displayed tan infrared reflectance. As a j whole, the stand of white pine was in fairly good condition but with some I Icwer branch dieback, perhaps due to crowding and sunlight shading.
i Eastern redceda rs were in good condition across the study site in
] general.

\ cimens. These trees were either black oak (Quercus velutina), red oak (Quercus rubra), or shingle oak (Quercus umbricaria). Diagnoses were
.- based on symptom expression in the field. Symptom development begins in i
the upper crown of infected trees. Leaves exhibit marginal scorching, a moisture stress symptom, and often fall from the tree. Leaf scorch symp-tems develop because the fungus multiplies in the vascular system, effec-
~
tively blocking the uptake of water. The disease develops rapidly in the 7
red oak group (which includes black oak and shingle oak), spreading throughout the entire tree. Infected trees in this group are of ten killed in a single season. Disease development in white oaks is much slower. Symptom expression is usually confined to a few branches each year. White oaks decline over a period of several years.
a
- Once a tree dies, the fungus produces mycelial mats underneath the outer bark. The mycelial mats, c aressure pads", often split the bark, a
exposing the pad surface upon which spores are produced. The spores have
'a fruity odor that is attractive to the sap- and bark-feeding beetles that vector the fungus to healthy trees. Pressure pads are fo med in the
- late summer of death if adequate moisture is available. If moisture is
~~
limiting, pads may not form until early spring if at all (Boyce,1957; Tainter and Gubler, 1973). Invasion of the oak-wilted trees by secondary disease organisms inhibits pad forma tion (Shigo, 1985; Tainter and Gubl e r,19 73) .
- Oak wilt symptoms were observed at Sites 1, 5, 6 and 7. The disease
~( !
w was confinned in the laboratory for the first time on samples collected from Site 1. Oak wilt appears to be the major cause of cak mortality.
1 11 j
l l
I Dutch elm disease (DED), caused by the fungus Ceratocystis ulmi, was identified as the stress factor on American elm (Ulmus americag) trees.
Diagnoses were based on visual symptoms: wilting, dieback of branches, and discoloration of the vascular system. DEO is a vascular disease similar to oak wilt. It has been devastating on American elm (Ulmus !
americana') and other native species because it is caused by an "introduced" pathogen against which native American elms have not deve-
. loped genetic resistance. OED was encountered at Sites 8 and 9.
A third disease that was encountered was root and butt rot. Root and butt rot was observed on plantation grown white pine (Pinus strobus) at Site 7. Root and butt rots are caused by a variety of fungi capable 2
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 l i
foliage. Fruiting bodies (basidiocaps) 'of the causal fungi, when they i occur, are usually formed in the fall. Decay and discoloration and fungal mats can be observed at the base of the trunk and on large roots just under the soil surface.
, A number of tree species, including black ca. ay (Pinus serotina), ~
1 hickory (Carya ovata), red, black, white and shingle oaks (Quercus r_uby, u i 1
h velutina, h alba and h imbricaria) and red maple ( Acer rubrum), i i

exhibited symptoms of dieback and decline. The dieback and decline symp-
..a tems varied with the species but in general were thinning crowns, small j
. ., pale foliage and branch dieback. While it is impossible to determine the T
4 exact cause of the decline, such symptoms are of ten indicative of a root problem. When the root system is not functioning sufficiently to meet the needs of the above-ground parts, decline begins. Branch dieback 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 ext ended i
drought, root rots, or site disturbances that physically damage roots.
4 i
The stressed condition of a number of oak trees was attributed to locally unf avorable edaphic conditions. These trees were found growing on slopes or ridges with shallow gravelly soil. On these sites, tree and shrub growth was thin and less vigorous than generally observed; ground ,
)~ cover was sparse. This habitat appears to be marginally suited for good veget tion growth. The occurrence of very hot, dry summers and sever e cold winters over the past several years could cause trees growing in
. such a habitat to eventually exhibit decline and dieback symptoms.
4 i
~~
Edaphic factors also combine with site temperature and rainfall )
I characteristics to affect vegetation heal th. The US Department of s
Agriculture Soil Consarvttion Service classifies the three most commonly observed soil types of the study site as Calwoods, Gorin or Mexico silt i
, 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 l i 13 l
0 l
.. . _= _
O loam or silty clay loam. Pemeability to water and available water capa-
,(j city of these soils are the primary characteristics that affect pl ant g rowth. Each soil has a large water holding capacity but also a low per-meability to water and low available water capacity. With ample precipi-tation these soils absorb large quantities of water and because of their low permeabili ty rates can become waterlogged. Waterlogged sofis 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 that interfere with defense reactions of the host pl ant (Schoeneweiss, 1975).
... N Alt ernately , during the hot, dry summe rs , such as occurred in several recent years, these soils began drying. Because these soils are "composed of a high percentage of clay particles that tenaciously bond to water molecules, water is much less available to plants. In periods of e high transpiration, plants growing in these types of soils igenerally can-not absorb and translocate sufficient amounts of water to continue nor-
~
mal, or in some cases even sustainable, growth rates. Thus they may l become dahydrated, wilt and possibly die, a

, Twig samples were collected from a black cak exhibiting a thinning i crown, defoliation and leaf scorch (slide 17). Ceratocystis fagacearum, the causal organism of oak wilt (0W), was isolated from a twig that showed the vascular discoloration symptomatic of the disease. Although
-- oak wilt symptoms have been observed in past years, this is the first laboratory confirmation of the disease. Three additional black oak spe-cimens (represented by slides 15 and 20) also exhibited characteristic OW symptoms. Basidiocarps (fungal fruiting structures, slide 18) of a wood-rotting fungus were observed on dead oaks in the general area. The oaks
- were probably killed by OW, with wood rot occurring secondarily. One shagbark hickory (slide 16) had two large, dead trunks that forked from
]
the same base. One fork had been dead for some time while the other died recently. Both trunks were infested with wood-boring insects (slide 19).
Another dead hickory within 50 meters was also infested with borers. Two
. stressed maples were observed at this site: one was damaged by wind and
, the other was in a general state of decline. I Site 2 This site is located in a timber management area and is charac-terized by the shallower soils usually found in the heavily timbered areas of the region. Four individual stressed oak specimens and several
,, stressed unde rs tory oaks were observed on this site. One oak was
, stressed from a fungal disease caused by a Fomes sp. (slide 13), and many of the understory shrubs were infected with a fungal canker disease. Two 15 i

A large black oak approximately 14 inches in diameter was almost compte -
17 i i
tely dead at this site. This year's leaves were still attached, indi-cating relatively recent decline. The suspected cause of . stress that has
, probably contributed greatly to the decline of this specimen is the site
'I condition alone. Of other similar-sized black oaks in the immediate vicinity, none were living. Outch Elm disease is th'e probable cause of
- iesth of two elm trees at this site (slide 27).
Site 9 This site was generally characterized as a low, swampy area with heavy undergrowth cf such species as wild grapes, impatiens and goose-
- berry. The entire stand was full of dead and dying trees. Outch Elm disease was considered the cause of death of one elm tree (slide 9).

(slide 10) and a red maple (slides 29 and 30), from a combination of 4
environmental and biotic factors, have resulted in stress. All understory hickories had the same fungal leaf spot disease observed on
, the hickortes at Site 4. A basswood tree exhibited yellowing leaves and a severely deflotated canopy. This stressed condition was most probably caused by a fungal leaf disease.

g 1. 0 INTRODUCTION
\- In accordance with Appendix B, Section 5.4.1 of the the following report was ;
Callaway Plant Operating License, prepared by Union Electric on all changes in plant design, operation, tests or experiments which involved a potentially significant unreviewed environmental question in accordance with Section 3.1 of Appendix B.
This report covers all plant modifications that were 1987,'through December 31, 1987 completed fron January 1, During 1987 there were two plant modifications that i involved a potentially significant unreviewed environmental question. The interpretations and conclusions regarding these plant modification along with a description of the changes are presented below. ,
2.0 ENVIRONMENTAL EVALUATIONS 2.1 Callaway Modification Package 86-0070 2.1.1 Description of Change This change involved the installation of underground piping from the oily waste building to the equalization basin and the instcllation of a weir at Lagoon number 1. ,
This change provides an alternate discharge path for the waste water from the oily waste separator.
2.1.2 Evaluation of Change ,
The installation of the underground piping and the weir did not result in a significant increase in any adverse environmental impact, since all measurable non-radiological environmental effects were confined to the area previously disturbed during site preparation and I There was no increase in effluent plant construction.since this change provided a discharge path for released, oily waste water to Lagoon No. 1, from which no discharge is allowed. Therefore, this change did not constitute an unreviewed environmental question per section 7.1 of Appendix B to the Callaway Plant Operating License.
2.2 Callaway Modification Package 86-0111 2.2.1 Description of Change f
This change involved removal and restoration of nine J environmental a.'.r sampling locations and modifications to I five environmental air sampling stations and two ground water sampling wells. This change reduced the number of air sampling stations to the number required in the
( Callaway Plant Technical Specifications. The environmental air sampling stations and ground water stations were modified to improve reliability and personnel sa fety.

I 2.2.2 Evaluation of Change l r
! There were 14 existing environmental air sampling l stations. Five of these were refurbished resulting in a l '
i minor amount of additional earth work. This relatively I insignificant impact was more than offset by the' L
- restoration of the other nine sites. Therefore, there was !
no significant increase in any adverse environmental +
impact previously evaluated by NRC and no unreviewed ,
l environmental question. !
