1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2018 for the Union Electric Company (dba Ameren Missouri) Callaway Energy Center.

The objectives of the REMP are to monitor potential critical pathways of radioactive effluent to man and determine the radiological impact on the environment caused by operation of the Callaway Energy Center. The Radiological Environmental Monitoring Program was initiated in April 1982.

The Callaway Energy Center consists of one 3565 MT pressurized water reactor, which achieved initial criticality on October 2, 1984. The plant is located on a plateau approximately ten miles southeast of the City of Fulton in Callaway County, Missouri and approximately eighty miles west of the St. Louis metropolitan area. The Missouri River flows by the site in an easterly direction approximately five miles south of the site at its closest point.

Tabulation ofthe individual analyses for the year 201 8 is included in Part II ofthis report.

SUMMARY

The Radiological Environmental Monitoring Program, as required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Callaway Energy Center is described herein.

Results for the year 201 8 are summarized and discussed.

For the year, the Callaway Energy Center was operated in compliance with Offsite Dose Calculation Manual (ODCM) and Radiological Effluent Controls (REC) requirements. Results from the REMP indicate the Callaway Energy Center has had no significant radiological impact on the health and safety of the public or on the environment.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Callaway Energy Center is to assess the impact of the plant on its environment. For this purpose, samples are collected from waterborne, airborne, ingestion and terrestrial pathways and analyzed for radioactive content.

Direct radiation levels are monitored by thermoluminescent dosimeters (TLD5).

Sources of environmental radiation can include the following:

(1) Natural background radiation arising from cosmic rays and primordial radionuclides; (2) Fallout from atmospheric nuclear detonations; (3) Releases from nuclear power plants, planned or accidental; and (4) Industrial and medical radioactive waste.

Effects due to operation of the Callaway Energy Center must be distinguished from those due to other sources in interpreting the data.

The indicator-control concept is a major interpretive aid; where feasible the design of the Callaway Energy Center program has both indicator and control stations. Most types of samples are collected at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.

The monitoring program includes analyses for iodine-131, a fission product, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants.

Most samples are analyzed for gamma-emitting isotopes, with results for the following groups quantified: zirconium-95, cesium-137, and cerium-144. These three gamma-emitting isotopes are selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation. Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about I 0% of the total activity of fission products ten days after reactor shutdown. On the other hand, ten days after a nuclear explosion, the contributions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963).

The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and cerium-141 These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the next group, manganese-54, cobalt-58 and-60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant effluents, but are not produced in significant quantities by nuclear detonation.

Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as analytical monitors and should not be considered radiological impact indicators.

Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including pre-operational data. Results of the monitoring program can be related to those obtained in other parts of the world. Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g. a nuclear accident.

3.2 Program Description The sampling and analysis schedules for the environmental radiological monitoring program at the Callaway Energy Center are summarized in.Tables 5.1 and 5.2 and briefly reviewed below. Table 5.1 identifies sampling locations and specifies as to type (indicator or control) and its distance, and direction relative to the reactor site. The types of samples collected at each location, required analyses and the frequency of collections are presented in Table 5.2.

To monitor the air environment, airborne particulate and airborne iodine samples are collected by continuous pumping, at six locations. The airborne particulates are collected on glass fiber filters and the airborne iodine through activated charcoal cartridges. Both filters and cartridges are exchanged weekly. Airborne particulates are analyzed for gamma-emitting isotopes. Charcoal cartridges are analyzed for iodine-i 31.

The ingestion pathway is monitored by sampling of milk (if available), fish and green leafy vegetation.

Milk samples are collected monthly when animals are on pasture and monthly the rest of the year.

There were no milk indicator stations identified by the Land Use Census for the subject year. The control station continued to be collected. Samples are analyzed for iodine-131 and gamma-emitting isotopes.

Monthly during the growing season, edible green leafy vegetation is collected from both indicator and control locations. Vegetation samples typically consist of mustard greens, turnip greens, cabbage, lettuce, collards, radish greens, swiss chard, broccoli and poke. Other edible broad leaf vegetation is collected if primary varieties are not available. The samples are analyzed for iodine-131 and other gamma-emitting isotopes.

Feed crops (soybeans, sorghum, corn) are collected from locations FC-i through FC-4. FC-i, FC-2 and FC-3 are located on Ameren property traversed by the discharge pipeline. The samples are collected at harvest and analyzed for tritium and gamma emitting isotopes. FC-4 is a control location, beyond the influence of plant operations. Feed crops are grown for animal feed and not for human consumption. The soybean field for sample FC-1 is planted by the Missouri State Department of Conservation (MODOC) to provide feed to wildlife living in the Reform Wildlife Conservation Area. MODOC did not plant the field this year and there was no crop to sample.

The waterborne pathway is monitored by sampling surface water, groundwater and drinking water, and bottom and shoreline sediments. Water samples are analyzed for tritium and gamma-emitting isotopes, and sediments are analyzed for gamma-emitting isotopes.

The waterborne pathway is also monitored by upstream and downstream semiannual collections offish. The five most abundant recreational or commercial fish species are collected. Samples are analyzed for gamma-emitting isotopes.

Monthly composite samples of surface water from the Missouri River are collected from one indicator location (502) and from one control location (501). The surface water samples are composites of daily collections by automatic river samplers.

Onsite surface water from nine ponds is analyzed for tritium and gamma-emitting isotopes. The collection frequencies are semiannually.

To monitor possible sources of ground water contamination due to plant operations, non-potable ground water samples were collected monthly or quarterly from well locations both onsite and along the discharge pipeline. The samples were analyzed for tritium and gamma-emitting isotopes.

4

3.2 Program Description (continued)

Potable well water samples are collected quarterly from the plant drinking water supply, neighboring property owners, and from the town of Portland, MO. The samples were analyzed for tritium and gamma-emitting isotopes.

River bottom sediment is collected semiannually at the plants intake (A) and discharge (C). The samples are taken from water at least 2 meters deep to prevent influence of bank erosion. Shoreline sediments are collected semiannually in the same area as bottom sediment. These samples are collected within two feet of the edge of the water. The samples are analyzed for gamma-emitting isotopes.

The direct ambient gamma radiation pathway is also considered. This exposure is monitored by thermoluminescent dosimeters (TLDs) at forty-four locations in and around the Callaway site. The TLDs are placed in 16 sectors around the plant as specified in the ODCM-RECS. Five ofthe TLD stations have neutron monitoring capability and three locations are designated as controls. TLDs are exchanged and analyzed quarterly.

Soil is collected annually from seven indicator locations (F2, PR3, F6, PR7, W2, W3, and W4) and two control locations (M9, Wi) to monitor the terrestrial environment. The samples are analyzed for gamma-emitting isotopes.

3.3 Program Execution The program was executed as described in the preceding section with the following exceptions.

(1) Airborne Particulates and Iodine.

The Air sampler station A-li found not operating 3/28/18, samples had lower volume (CR 201801634). Air station A8 was found not running 6161i8 for about 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> (CR 201802861).

(2) Ground Water:

Water was frozen during the 1/i 6/1 8 collection event inside the old blowdown line. The well was dry for the 1/20/18 collection event at location Ui MW-047 (CR 201801736).

(3) Broadleaf Vegetation:

Edible broadleaf vegetation, collected at the five area gardens was available for harvest May through October 201 8 with the following exceptions: Samples were not available at locations V-9, V-i2, V-16 in April dueto the gardens not yet producing. Gardens at locations V-li and V-i6 were not producing in May. No sample was available at location V-9 for the 8/14/18 collection. No sample was available for location V-i 1 forthe 7/9/18 orthe 8/14/i 8 collection. No vegetables were available at location V-16 for the 8/14/18 or the 10/9/18 collections. Location V-l8 (Ward residence) was dropped from the program in 2018 due to poor performance.

(4) Inedible crops:

Inedible crops were not collected at location FC-i during the 2018 collection due to the field not being planted.

(5) Milk:

Milk sampling was discontinued at location M-9 after the 4/24/i 8 sampling event due to the lack of an indicator location. Vegetation sampling is sufficient to comply with the requirements of the ODCM.

3.3 Program Execution (continued)

(6) Direct Radiation The fourth quarter TLD at location IDM-61 was found to have water intrusion. The results of the reading were evaluated by the vendor and found to be inconsistent with the previous 7 quarters (location was established in the first quarter of 201 7). Therefore this TLD was treated as a missing sample (CR 201900133).

3.4 Laboratory Procedures The iodine-131 analyses in milk were made using a sensitive radiochemical procedure involving separation of the iodine by ion-exchange, solvent extraction and subsequent beta counting.

Gamma-spectroscopic analyses were performed with HPGe detectors. Levels of iodine-i 31 in vegetation and concentrations of airborne iodine-i 31 in charcoal samples were also determined by gamma spectroscopy.

Tritium was measured by liquid scintillation.

Analytical Procedures used by Environmental, Inc. are on file at the laboratory and are available for inspection. Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dept of Energy, Edition 28, 1 997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1984.

Environmental, Inc. Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained. Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2018). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs. Results obtained through Quality control samples and crosscheck program results are presented in Appendix A.

Environmental TLDs are processed by Stanford Dosimetry, LLC.

3.5 Program Modifications Vegetation sample station location Vi8 was deleted 4/26/18 due to poor performance. There are still one more than the required number of sampling locations after the deletion of location Vi 8.

Milk sampling at station M9 was deleted due to the lack of a corresponding indicator station.

Broadleafvegetation sampling fulfills the requirements ofthe ODCM.

3.6 Detection and Reporting Limits Table 5.3 gives the minimum required detection limits for radiological environmental sample analysis. For each sample type, the table lists the detection level for each isotope. The lower limit of detection (LLD) used in this report is described in NRC Regulatory Guide 4. 1 Rev. I Program for Monitoring Radioactivity in the Environs of Nuclear Power Plants and the NRC Radiological Assessment Branch Technical Position, Rev. 1, November 1979, An Acceptable Radiological Environmental Monitoring Program.

3.7 Land Use Census The Land Use Census is performed annually during the growing season. In 2018, the survey was conducted October 1 1 201 8 within a live mile canvassing radius ol the Callaway Energy Center.

The area around the plant was divided into 16 meteorological sectors. The locations ofthe nearest resident, nearest milk animal, and nearest garden of greater than 500 square feet producing broadleaf vegetation were identified.

The results of the census are presented in Table 5.4. The table includes radial direction and distance from the Callaway Energy Center for each location. The bearings listed in Table 5.4 were measured from the Callaway Plant to the sample location.

The following revisions are reflected in the 2018 report. In SectorA, James and Erica Wagoner are now the closest resident in this sector. In Sector F, Davis Wimmer is no longer planting a broadleaf garden, there is no replacement in this sector.

All residents included in the summary were verified by the Callaway County Assessors GIS aerial photography.

During the survey a water well was identified at 9549 County Road 464, Portland, MO 65067. This well is owned byAmy Dillon. No irrigation uses ofthe Missouri River, within 10 miles downstream, were identified during the survey. The Missouri Department of Natural Resources confirmed that no new drinking water intakes have been located along the Missouri River within ten (1 0) river miles downstream from the plant.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for the listing in Table 5.5.

Results are summarized in Table 5.6 as recommended by the Nuclear Regulatory Commission.

For each type of analysis and sample medium, the table lists the mean and range of all indicator and control locations, as well as that location with the highest mean and range.

The tabulated results of all measurements are not included in this section, although references to these results will be made in the discussion. A complete tabulation of results for 201 7 is contained in Part II of the Annual Report on the Radiological Environmental Monitoring Program for the Callaway Energy Center.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents The Fukushima Daiichi nuclear accident occurred March 11, 2011. There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 201 8. The last reported atmospheric test was conducted on October 16, 1980 by the Peoples Republic of China. There were no reported atmospheric nuclear tests in 2018.

4.2 Program Findings Airborne Particulates and Iodine No gamma emitting isotopes were identified other than naturally occurring Be-7. There was no I-1 31 activity detected in any ofthe charcoal canister samples.

Air sampling for 201 8 indicates no radiological effects of plant operation.

Direct Radiation (TLDs)

Forty-four gamma sensitive TLDs were placed in 16 sectors around the Callaway site.

Measurements from forty-one indicator locations averaged 1 5.2 mrem/quarter and the three control locations averaged 14.4 mrem/quarter. Readings ranged from 10.9 to 17.4 mrem /quarter, with the highest from the control location CA-IDM-27, averaging 16.7 mrem/quarter. The differences are statistically insignificant. The TLD readings were consistent with the results for the years 2000 through 2017 as detailed in table 5.7.

Five neutron sensitive TLDs were placed in locations at the Site Boundary closest to the Independent Spent Fuel Storage Facility Installation (ISFSI) and at a control location approximately 14 miles from the site. There was no significant measureable neutron dose and there was no effect from the ISFSI in 2018.

Milk There are no milk indicator stations. No iodine-I 31 was detected in samples from the control station during the duration of sampling. No gamma-emitting isotopes, with the exception of naturally occurring potassium-40, were detected in milk. Milk data for 2018 show no radiological effects of plant operation. Sampling was discontinued since there are not enough sampling locations to fulfill the milk sampling requirement. Leafy green (broadleaf) vegetation sampling was performed in lieu of milk sampling.

8

Broadleaf Vegetation There was no I-i 31 activity detected in broadleaf vegetation samples. No gamma-emitting isotopes were detected in broadleaf vegetation samples except for naturally occurring potassium-40.

Vegetation data for 201 8 show no radiological effects of plant operation.

Non-Food Crops Soybean samples were analyzed for tritium and gamma-emitting isotopes. Slight tritium activity was detected at three of the seven samples taken. No gamma-emitting isotopes, except for naturally occurring potassium-40, were detected in non-food crops.

Fish Edible portions of fish were analyzed by gamma spectroscopy. No gamma-emitting isotopes, except for naturally occurring potassium-40, were detected in fish.

Soil Cesium-137 activity was detected at thirteen of the eighteen sample locations at an average concentration of 284 pCi/kg dry. 337 pCi/kg dry was the average activity for the ten of fourteen positive indicator locations. Three of the four control samples were positive for Cesium-i 37 with an average activity of i 09 pCi/kg dry. The cesium-i 37 activity is consistent with levels observed from i999 through 20i7; these levels are attributable to the deposition offalloutfrom previous decades.

Surface Water Low level tritium was detected in two of the twelve samples collected at the downstream location 502 at an average concentration of 347 pCi/L. There was no tritium detected in the remaining ten samples from 502. No gamma-emitting isotopes were detected.

Surface Water, Ponds Eighteen pond samples were analyzed for 20i 8. No tritium activity or gamma activity was detected.

Drinking Water Wells (potable water)

Sixty samples from fifteen different locations were analyzed for tritium and gamma-emitting isotopes. No tritium or gamma-emitting isotopes were detected.

Wells and Ponds (non-potable water)

Groundwater samples from deep wells F-05 and F-i5 were analyzed for tritium and gamma-emitting isotopes. There were no tritium or gamma emitting isotopes detected. Wells MW-31 MW- ,

34, MW-36, MW-39, MW-47, MW-58, and MW-59 were installed during the 20i4 LSI (the 20i4 LSI is described in detail in the Callaway Energy Center 2014 Annual Radioactive Effluents Release Report). These wells continue to monitor the natural attenuation of tritium which decreased significantly during 20i5 and continued to decrease in 2016 and 20i7 and decreased again in 201 8. Tritium activity was detected in i 9 of 27 samples from these wells. The highest concentration was measured in MW-58 which peaked at 9i i pCi/L in January. By October, the concentration in 9

MW-58 had fallen to 516 pCi/L. The average concentration among positive results for these wells was 776 pCi/L. this decline has been steady since the December of 2016. The contamination is being remediated by monitored natural attenuation. There are no active leaks.

Wells GWS, 936, 937B, 937D, 939R, 940, 941 and IFSFI Sump are located in the Plant Protected Area, adjacent to the power block. Tritium activity in these wells is believed to be the result of washout from gaseous effluents. The low level tritium activity observed in wells MW-014 is likely due to residual low level contamination from moisture carryover during normal operation of air release valves (ARVs) in manholes 5 and 6B on the now-retired discharge pipeline. The pipeline was replaced in 2008 and there has been no new contamination ofthis area since then. The existing contamination is being remediated by monitored natural attenuation. There are no active leaks and the results are consistent with 201 5 through 2018.

Sediments Samples of shoreline and bottom sediments were collected in May and October 2018 at both an indicator and a control location and analyzed for gamma-emitting isotopes. Cesium-137 was detected in one of the two bottom sediment samples, in the May indicator sample, at a concentration of 44 pCi/kg dry weight, and was detected in one of the two shoreline sediments, in the May control sample, at concentration of 46 pCi/kg dry weight. These results are consistent with results from previous years. There were no other gamma-emitting isotopes detected excepting naturally occurring potassium-40 in any of the sediment samples.

The complete appendix is included in March, June, September and December monthly progress reports only.

January, 2018 through December, 2018

Appendix A Interlaboratorv/ Intralaboratorv Comparison ProQram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratorys analytical procedures and to alert it of any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

Table A-i lists results that were obtained through participation in the RAD PT Study Proficiency Testing Program administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

Table A-2 lists results for thermoluminescent dosimeters (TLDs), via irradiation and evaluation by the University of Wisconsin-Madison Radiation Calibration Laboratory at the University of Wisconsin Medical Radiation Research Center.

Table A-3 lists results of the analyses on in-house spiked samples for the past twelve months. All samples are prepared using NIST traceable sources. Acceptance criteria is detailed on Attachment A page A2.

Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house blank samples for the past twelve months. Data for previous years available upon request.

Table A-5 lists analytical results from the in-house duplicate program for the past twelve months. The Precision Acceptance limit is +/-25% of the mean for Sr-89,90, Gross Alpha and Gross Beta or the 2-sigma uncertainty overlaps the mean value. For all other analytes the precision acceptance limit is

+/-20% of the mean or the 2-sigma uncertainty overlaps the mean value.

Results obtained by Environmental, Inc. Midwest Laboratory as a participant in the crosscheck program for proficiency testing in drinking water conducted by Environmental Resource Associates (ERA).

b A transcription error caused the Cs-137 result submitted to be understated by a factor of 10.

The actual result obtained was slightly higher than the acceptance criteria for the study.

A Quick Response proficiency test was analyzed to help determine the cause of the high result. (See ERW-3832 above)

No definitive cause for the previous high Cs-i 37 result was determined.

C An investigation was conducted on the apparent cause of failure in the Uranium isotopic PT analysis. In order to get to the root cause of the failure a NIST U-natural 4321 d-standard was purchased and a new U-232 diluted tracer was standardized.

The analysis was rerun and the results were found to be within the acceptance criteria. It appears that the original U-232 tracer used in the analysis may have been compromised (concentrated) resulting in a very high negative bias.

a Provided in the series for sensitivity evaluation. MAPEP does not provide control limits.

a The lab was in the warning zone on this study(biased low). The sample was rerun applying an aggressive oxidation technique to remove a complexing agent that is utilized in the early steps of the procedure. Reanalysis was acceptable with this enhanced technique.

An investigation was performed to determine reason for the failure of the Ra-226 result. A backup solution was reanalyzed with acceptable results. The current study as well as a past study were reanalyzed with acceptable results.

No conclusion has been currently drawn from the results of this investigation.

Results obtained by Environmental, Inc. Midwest Laboratory (EIML) as a participant in the crosscheck program for proficiency testing administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the Environmental Measurements Laboratory Quality Assessment Program (EML).

b Laboratory codes as follows: ERW (water), ERAP (air filter), ERSO (soil), ERVE (vegetation). Results are reported in units of pCi/L, except for air filters (pCi/Filter), vegetation and soil (pCi/kg).

C Results are presented as the known values, expected laboratory precision (2 sigma, 1 determination) and control limits as provided by ERA.

d Reported result was higher than ERAs upper acceptance limit. An investigation was initiated. The sample was run with a pre-treatment technique. Rerunning the analysis with this pre-treatment gave a result of 7.30 pCi/total.

Going forward all samples for Am-241 will be analyzed utilizing this pre-treatment.

e The ERA results for Bi-212 and K-40 were outside the acceptable limits. The sample analysis was rerun utilizing a different library with acceptable results. The library used in the original analysis contained many more energies than the second library used, rendering a less reliable result for Bi-212. The K-40 value was overstated due to the use of a background spectrum analysis that had not fully quantified the K-40 present.

Going forward a table has been created to track the historical results for the background subtraction for each HPGe detector so that any changes in background can be more easily identified.

APPENDIX B. DATA REPORTING CONVENTIONS Data ReporUng Conventions 1 O. All results, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements Each single measurement is reported as follows: x+/-s where: x value of the measurement; 5 = 2c counting uncertainty (corresponding to the 95% confidence level).

In cases where the result is less than the Minimum Detectable Concentration (MDC), L, it is reported as: < L, where L = the Minimum Detectable Concentration based on 4.66c uncertainty for a background sample.

3.0. Duplicate analyses If duplicate analyses are reported, the convention is as follows.

3.1 Individual results: For two analysis results; x1 +/- s and x2 +/- 2 Repoed result: x +/- s; where x = (1/2) (x1 + x2) and s (1/2) +

3.2. Individual results: < L1 , < L2 Reported result: < L, where L lower of L1 and L2 3.3. Individual results: x +/- s, < L Reported result: x +/- s if x L; < L otherwise.

4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average and standard deviation s of a set of n numbers x1, x2 . . . x are defined as follows:

1 x x 5=

\/ n-i 4.2 Values below the highest MDC are not included in the average.

4.3 If all values in the averaging group are less than the highest MDC, the highest MDC is reported.

4.4 If all but one of the values are less than the highest MDC, the single value x and its associated two sigma error is reported.

4.5 In rounding off, the following rules are followed:

4.5.i. If the number following those to be retained is less than 5, the number is dropped, and the retained numbers are keptunchanged. As an example, 11.443 is rounded offto ii.44.

4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by i As an example, i i .445 is rounded off to i i .45.
