1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2011 for the Union Electric Company (dba Ameren Missouri Corp.),

Callaway Plant.

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 Callaway Plant. The Radiological Environmental Monitoring Program was initiated in April 1982.

Callaway Plant consists of one 3565 MWt 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 of the individual analyses for the year 2011 is included in Part II of this report.

2.0

SUMMARY

The Radiological Environmental Monitoring Program, as required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Callaway Plant is herein described. Results for the year 2011 are summarized and discussed.

For the year, the Callaway Plant was operated in compliance with Off Site Dose Calculation Manual (ODCM) requirements. Comparison of results for 2011 show no significant differences to historical data. Results from the REMP indicate the Callaway Plant has had no significant radiological impact on the health and safety of the public or on the environment.

The detection of iodine-131 in charcoal cartridges and particulate filters, milk and water for the period of March 17 through May 8, 2011 is consistent with and attributable to radioactive elements released from the Fukushima Daiichi reactors or fuel pools in the aftermath of the March 11, 2011 Japanese earthquake and tsunami.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Callaway Plant 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. Ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLDs).

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.

In interpreting the data, effects due to operation of the Callaway Plant must be distinguished from those due to other sources.

A major interpretive aid in assessment of these effects is the design of the monitoring program at the Callaway Plant, based on the indicator-control concept. 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.

An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the Callaway site. 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 10% 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-?, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as calibration 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 Plant 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, direction, and sector 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 particulates and airborne iodine samples are collected by continuous pumping, at five locations. The airborne particulates are collected on glass fiber filters and the airborne iodine through an activated charcoal cartridge. Both filters and cartridges are exchanged weekly. Airborne particulates are analyzed for gamma-emitting isotopes. Charcoal cartridges are analyzed for iodine-131.

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

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

Soybeans are collected from locations FC-1 through FC-4. FC-1, 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.

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 of fish. 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 (S02) and from one control location (S01).

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

To monitor possible sources of ground water contamination due to plant operations, non-potable ground water is collected monthly or quarterly from 48 well locations both onsite and along the discharge pipeline. The samples are analyzed for tritium and gamma-emitting isotopes.

Potable well water samples are collected quarterly from the plant drinking water supply, neighboring property owners, and from the town of Portland, MO.

River bottom sediment is collected semiannually at the plant's 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.

3.2 Program Description (continued)

Another pathway considered is direct ambient gamma radiation. This exposure is monitored by thermoluminescent dosimeters (TLDs), at forty-three locations in and around the Callaway site. The TLDs are placed in 16 sectors around the plant as specified in the ODCM-RECS. Three locations are designated as controls (IDM-26, IDM-27 and IDM-60). TLDs are placed at each location and exchanged and analyzed quarterly.

To monitor the terrestrial environment, soil is collected annually from seven indicator locations (F2, PR3, F6, PR7, W2, W3, and W4) and two control locations (M9, W1). The samples are analyzed for gamma-emitting isotopes.

Additional sampling for soil, precipitation and ground water was conducted in 2011. Results are included in Part II, App. C.

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

(1)Surface Water:

The surface water samples are composites of daily collections by automatic river sampler from two locations, S01 and S02. The sampler at S01 was out-of service for 163 days in 2011 (CAR 201200836). The sampler at S02 was 94% operable; down-time approximately 20 days. During sampler downtime, composites of daily grab samples are prepared and submitted for analysis.

Surface water from the Unit 2 pond (CA-SWA-UNIT 2) was not collected in January, 2011. The pond was frozen.

(2) Ground Water:

Ground water collection was intermittent for monitoring wells U1MW-28 and MW-939. These wells were added to the program in the fourth quarter, 2010, and were dry upon initial sampling. Only one collection was made from the U1 MW-28 well in 2011. The sample was analyzed for tritium only, there was insufficient sample for gamma isotopic analysis. The monitoring well MW-939 was analyzed for tritium only in May, June and October, 2011, there was insufficient sample for gamma isotopic analyses. The well was dry from July through September, 2011.

The ground water sump location (GWS) was not sampled for the months of May through September. The site was considered unsafe, due to electrical hazards.

(3) Vegetation:

No samples were available from station V-9 for the August 9, 2011 collection. The garden suffered damage from animals.

No vegetation samples were available from station V-11 for the June 29, 2011 collection. The garden was not producing, due to animal damage.

Station V-14 was dropped from the program in July, 2011, due to the death of the participant.

No vegetation samples were available from station V-15 after the August 8, 2011 collection, the garden quit producing.

(4) Non-Food Crops:

Soybeans were not available for harvest from four fields at two locations, FC-1A, FC-1 8, FC-1 C, FC-3C. There were no crops planted in 2011.

5

3.3 Program Execution (continued)

(5) Direct Radiation:

Both TLD and fade dosimeter for location IDM-46 were missing for the 4th quarter, 2011. The TLDs were replaced. Vandalism is suspected.

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-131 in vegetation and concentrations of airborne iodine-131 in charcoal samples were also determined by gamma spectroscopy.

Tritium was measured by liquid scintillation.

Analytical Procedures used by Environmental, Inc. are on file and are available for inspection.

Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28, 1997, 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, 2009). 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

1. The vegetation sampling location, V-14, was dropped from the program in July, 2011, due to the death of the provider. Reference CAR 201105885.

2. Soil sampling station V3 was replaced with station M9, due to the death of the provider. Reference CAR 201108365.

3. The farm crop LLD requirement was revised, specific for Cs-134 and Cs-137. Reference CAR 201104343.

4. The definition of "growing season" was revised as "April 15- November 1, but variable according to weather conditions", consistent with the description in "Climate of Missouri", Hammer, Gregory R.

National Climatic Data Center (NCDC) of the National Oceanic and Atmospheric Administration (NOAA), January, 2006.

5. For the 2012 growing season, vegetation sampling location V16 will replace station V15, due to a history of poor production.

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. 1, "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 2011, the survey was conducted within a five mile canvassing radius of the Callaway Plant. The location of the nearest resident, milking animal, and garden greater than 50 square meters was identified by contacting residents by phone, mail and/or in field surveys for each of the sixteen meteorological sectors using the midpoint of the two units.

The Land Use Census was completed on October 18, 2011. The results of the census are presented in Table 5.4. The table includes radial direction and distance from the Callaway Plant for each location, determined by a Global Positioning System (GPS) receiver.

The census includes identification of drinking water wells along Mud Creek and Logan Creek. No new drinking water wells were identified in 2011.

No irrigation or drinking water intakes were found within 10 river miles downstream of the plant discharge point.

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 2011 is contained in Part II of the Annual Report on the Radiological Environmental Monitoring Program for the Callaway Plant.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents The Fukushima Daiichi nuclear accident occurred on March 11, 2011, releasing large amounts of radioactive isotopes into the atmosphere and Pacific Ocean. Positive iodine-131, cesium-134 and cesium-137 activities were detected in environmental background samples from March through May.

The accident, rated seven on the International Nuclear Event Scale (INES) compares with Chernobyl, rated level seven, and Three Mile Island rated level five.

4.2 Program Findings Results obtained show background levels of radioactivity in environmental samples collected beyond the plant property boundary in 2011. Tritium was identified in some groundwater samples collected within the Plant Protected Area and on Ameren property in the Missouri River alluvial plain. In no instances were REMP threshold reporting levels exceeded.

Airborne Particulates The five air particulate sampling stations (A 1, A7, A8, A9, and B3) are indicator locations. Station A-9 is located in Reform, MO, the community with the highest D/Q, station A-7 is on the outskirts of Fulton, Missouri, approximately 9.5 miles from the plant.

Gamma spectroscopic analysis of the air particulate filters yielded similar results for all locations. In 114 of the 260 samples tested, Beryllium-? measured above an LLD value of 0.16 pCi!m 3 , with an average activity of 0.21 pCi!m 3 . Beryllium-? is produced continuously in the upper atmosphere by cosmic radiation. No gamma emitting isotopes of plant origin were identified.

Airborne Iodine In the weeks following the Fukushima Daiichi accident, measurable iodine was detected in weekly collections of activated charcoal cartridge samples. For the weeks ending March 24, March 31 and 3

April 8, 2011, mean activity for all locations measured 0.058, 0.14 and 0.061 pCi/m , respectively.

For the week ending March 31, positive iodine activity was also detected on the particulate filters, with an average activity of 0.057 pCi/m 3 . Measurements throughout the rest of the year were below the 3

required lower limit of detection of 0.070 pCi!m . (CAR 201102767, CAR2011 03463)

Direct Radiation (TLDs)

Forty-three TLDs were placed in 16 sectors around the Callaway site. Measurements from forty indicator locations averaged 15.7 mrem/quarter and the three control locations averaged 14.6 mrem/quarter. Readings ranged from 10.4 to 18.5 mrem /quarter, with the highest from the location CA-IDM-27, averaging 17.1 mrem/quarter. The differences are statistically insignificant.

The TLD readings are consistent with previously accumulated data and no effects from plant operation were identified.

8

4.2 Program Findings (continued)

Following the Fukushima Daiichi accident, iodine-131 was detected in milk collected at location M-9.

For the April and May, 2011 collections, iodine activity measured 39.0 and 0.6 pCi!L, respectively.

Results remained below the detection limit of 0.5 pCi/L for all other sample collections.

(CAR 2011 03463)

No other gamma-emitting isotopes, except naturally occurring potassium-40, were detected in any of the milk samples. Detection of the iodine and potassium activity is consistent with findings of the National Center for Radiological Health (1968). Most radiocontaminants in cattlefeed do not find their way into milk due to the selective metabolism of the cow, common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine.

In summary, milk data for 2011 show no radiological effects of plant operation.

Vegetation There was no 1-131 activity detected in broadleaf vegetation samples. Measurements were below an LLD level of 37.7 pCi/kg wet weight in all samples.

Except for potassium-40, which was observed in all vegetation samples, all other gamma-emitting isotopes were below detection limits. No effect from plant operation is indicated.

Non-Food Crops Soybeans were sampled in October, 2011, and analyzed for tritium and gamma-emitting isotopes.

No tritium activity was measured above a detection level of 151 pCi/L in any of the samples.

Potassium-40 activity ranged from 2,797-14,237 pCi/kg wet weight and averaged 7,871 pCi/kg wet weight. All other gamma-emitting isotopes measured below detection limits.

No effect from the plant operation is indicated.

All gamma-emitting isotopes, except naturally-occurring potassium-40, in edible portions were below detection limits. The potassium-40 levels were similar at both indicator and control locations (2,647 and 2,573 pCilkg wet, respectively).

No plant effect on the fish population is indicated.

Cesium-137 activity was detected at both indicator and control locations, at average concentrations of 415 and 55 pCi/kg dry, respectively. The cesium-137 activity is similar to or less than levels observed from 1999 through 2010, these levels are generally attributable to deposition of fallout from previous decades.

Naturally-occurring potassium-40 averaged 11 ,480 pCilkg dry weight.

Analysis results for soil samples in 2011 were consistent with previously accumulated data and no plant operational effects were identified.

9

4.2 Program Findings (continued)

Surface Water Slight tritium activity above the detection limit of 171 pCi/L was observed in four of the twelve samples collected from the downstream location S-02. Measurements averaged 304 pCi/L.

Gamma-emitting isotopes measured below detection limits and were consistent with previously accumulated data.

Surface Water. Ponds To monitor possible sources of groundwater contamination due to plant operations, twelve onsite surface water locations (SWA) are included in the permanent REMP. Tritium was detected in one of four samples from the UHS pond at a level of 275 pCi/L. At the Unit 2 pond, one of three samples collected measured 185 pCi/L. The trace activity of H-3 in these ponds is believed to be the result of washout from gaseous effluents. All other sample results measured below a detection level of 177 pCi/L.

Gamma-emitting isotopes measured below detection limits. No plant operational effects were identified.

Drinking Water Wells (potable water)

In addition to potable ground water from wells D-01 and PW-01, the REMP includes nine additional potable water wells from adjacent properties and one additional potable water well from the town of Portland, MO. The samples were analyzed for tritium and gamma-emitting isotopes.

No tritium activity was measured above a detection level of 162 pCi/L in any of the samples. All gamma-emitting isotopes were below detection limits.

Analysis results for drinking water samples were consistent with previously accumulated data and no plant operational effects were identified.

Wells (non-potable water)

Ground water from wells F-05 and F-15 was tested for tritium and gamma-emitting isotopes. Both tritium and gamma-emitting isotopes measured below detection levels.

Forty-six additional indicator ground water locations, on-site and along the discharge pipeline, are included in the REMP. Tritium activity {above a detection limit of 172 pCi/L) was detected in 59 of the 284 samples tested, with an average activity of 641 pCi/L. The highest concentrations were observed from samples taken at location MW-939, with an average activity of 3015 pCi/L.

Wells OW-4, OW-5, GWS, 936, 937A to 937F, 938, 939, 940 and 941 are located in the Plant Protected Area, adjacent to the powerblock. Tritium activity in these wells is believed to be the result of washout from gaseous effluents. The positive iodine-131 activity detected at MW-936, was collected on March 30, 2011, and is attributed to the Fukushima event (CAR 2011 03463).

The low level tritium activity observed in wells MW-014, MW-017, MW-018 and MW-019 is due to residual low level contamination of the area downgradient from manholes 5 and 68. The contamination was caused by moisture carryover during normal operation of air release valves (ARVs) in the now-retired discharge pipeline. The exhaust of the ARV's was secured in 2007, and the pipeline was replaced in 2008. The new discharge pipeline has no ARV's and only a single vacuum breaker, which is completely contained to prevent possible leakage to the ground water. The old pipeline has been abandoned in place.

10

4.2 Program Findings. Wells and Ponds (non-potable water. continued)

Wells have been established along the pipeline corridor to monitor the old pipeline and to ensure there is no leakage from the new pipeline. Monitored natural attenuation will be utilized to remediate the low level residual tritium contamination.

Samples were also analyzed for gamma-emitting isotopes. No gamma-emitting activities were detected above the respective LLDs.

Sediments Bottom sediments were collected in April and October, 2011, and analyzed for gamma-emitting isotopes. Cs-137 was detected in one of two control samples at a concentration of 71.1 pCi/kg dry weight and one of the two indicator samples at a concentration of 116.1 pCilkg dry weight.

Potassium-40 activity ranged from 11,779 to 14,430 pCi/kg dry weight and averaged 13,058 pCi/kg dry weight.

Shoreline sediments were also collected in April and October, 2011. Trace Cs-137 activity was detected in one of two control samples at a concentration of 33.2 pCilkg dry weight and in two indicator samples at an average concentration of 57.5 pCi/kg dry weight. Potassium-40 activity ranged from 13,142 to 14,642 pCi/kg dry weight and averaged 14,072 pCi/kg dry weight.

Potassium-40 is a naturally occurring isotope. The slight cesium-137 activities observed are indicative of the influence of fallout deposition. All other gamma-emitting isotopes were below detection limits.

No effect from the plant operation is indicated.

Results are reported in Appendix A. TLD lntercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

January through December, 2011

Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's 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 laboratory's 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.

Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources 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 International lntercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

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. 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 REMP specific analytical results from the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors.

Complete analytical data for duplicate analyses is available upon request.

The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.

Results in Table A-7 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).

Attachment A lists the laboratory precision at the 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.

Out-of-limit results are explained directly below the result.

d MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive". MAPEP does not provide control limits.

Result of a repeat analysis was still unacceptable. ERA crosschecks for Am-241 were acceptable, but biased low.

Matrix spikes were prepared, ( 5.17 and 51.7 pCi/L), to verify method; results were acceptable, 4.4 and 47.5 pCi/L.

Am-241 has been added to the internal spike and blank program for 2012.

1 An error in percent recovery was found, result of recalculation, 427.3 +/- 18.8 Bq/kg dry.

9 No errors found in calculation or procedure, results of reanalysis; 1. 73 Bq/filter.

h The analyses were repeated through a strontium column; mean result of triplicate analyses, 304.2 Bq/kg.

The lab does not currently analyze soil for Tc-99, but is evaluating the procedure. After consultation with Eichrom, the analysis was repeated using a matrix spike correction. Mean result of triplicate reanalyses; 183.3 Bq/kg.

APPENDIX B DATA REPORTING CONVENTIONS B-1

Data Reporting Conventions 1.0. All activities, 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; s =2cr counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is less than the lower limit of detection L, it is reported as: < L, where L = the lower limit of detection based on 4.66cr 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 +/- s1 and Xz +/- s2 Reported result: x +/- s; where x = (1/2) (x1 + x2 ) and s = (1/2) ~ s; + si 3.2. Individual results: < L1 , < L2 Reported result: < L, where L = lower of L1 and ~

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 exa~ple, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation "s" of a set of n numbers x 1, x2 **. x" are defined as follows:

X =-n1 LX s---~ -\j~

4.2 Values below the highest lower limit of detection are not included in the average.

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

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

4.5 In rounding off, the following rules are followed:

4.5.1. If the number following those to be retained is less than 5, the number is dropped, and the retained numbers are kept unchanged. As an example, 11.443 is rounded off to 11.44.

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 1. As an example, 11.445 is rounded off to 11.45.

Appendix C. NON-RADIOLOGICAL MONITORING PROGRAM 1.0, Introduction Union Electric Company, d.b.a. Ameren Missouri, in accordance with federal regulations and a desire to maintain the quality of the local environment around Callaway Plant has implemented an Environmental Protection Plan, (EPP) contained in Appendix B of the Callaway Plant Operating License.

The objective of the EPP is to provide for protection of non-radiological environmental values during operation of the Callaway Plant.

This report describes the conduct of the EPP for the Callaway Plant during 2011.

2.0. Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2011.

3.0. EPP Non-compliances During 2011, there were no non-compliances with the EPP.

4.0. Nonroutine Reports There were no non routine reports submitted in accordance with the EPP, Section 5.4.2 in 2011.

5.0. Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, operation, tests or experiments installed during 2011, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2011, three plant changes could have involved a potentially significant unreviewed environmental question. The interpretations and conclusions regarding these plant changes along with a description of the change and activity are presented below.

MP 10-0032- New Non-safety Auxiliary Feedwater Pump Description of Modification:

Modification MP 10-0032 installed a new non-safety auxiliary feedwater pump, including piping, piping supports, valves, electrical power, instruments, and controls. As part of this modification a new transformer was installed plant west of the turbine building.

Evaluation of Change:

As part of the evaluation, both the Callaway Plant ER and FES-OL were reviewed for any previously evaluated adverse environmental impacts and any new adverse environmental impacts not previously evaluated. As part of this project, a new transformer was installed outside of the plant southwest turbine building stairwell on a flat area previously backfilled near the power block. The new transformer contains 488 gallons of transformer oil and does not have an oil collection device. However, any leakage of oil from the transformer would be easily observed and contained in and around the granular fill under the equipment for cleanup. It is highly unlikely that any oil released from this transformer would reach a storm water drainage area or any navigable waters of the US. The evaluation concluded that Installation of the replacement sections of the makeup and blowdown piping did not involve an unreviewed environmental question.

MP 10-0038. Revision 0 *Alternate Emergency Power Source Description of Modification:

Modification MP 10-0038, revision 0, installed a permanent alternate emergency power source to Callaway from the COOP substation. The modification will install a buried 13.8 kV transmission line from the COOP substation to a location near the Cooling Water Chemical Control Building where it will terminate at a 13.8 kV I 4160 transformer. The spare XNB transformer already on site was used for this transformer. This transformer will supply 4160 switchgear which will feed 4160 V power to either of the NB busses and to AP01, and the MCC for the non-safety aux feedwater pump which was recently installed. The spare XMB transformer contains 2170 gallons of oil and was installed over a transformer pit capable of containing the entire oil volume should the transformer fail.

The buried cable runs ESE from the COOP substation using the existing COOP Right-of-Way for approximately 3/4 of a mile, turns SE and enters the owner control area in the NW corner. The cable runs SE through the owner control area to the transformer pit located plant southeast of the radwaste building. The cable run required boring under two streams and avoidance of cultural resource site 256.

The cable was installed using linear construction that consists of trenching 2 feet or less in width and approximately 3 feet in depth.

Evaluation of Change:

As part of the Final Environmental Evaluation, both the ER and FES-OL were reviewed for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated. No environmental impacts were identified. For this modification, there were some temporary impacts due to burying the electrical cable. The buried cable was installed using linear construction that consists of a trench 2 feet or less in width. The Missouri State Regulations (1 0 CSR 20-6.200(8).8) has an exemption from storm water permit regulations for this type of construction. However, impacts from trenching will be managed using the appropriate best management practices (BMPs) and the area will be returned to its original state after completion of the project.

During the evaluation of the cable routing, Environmental Services Department (ESD) reviewed the Preliminary Jurisdictional Wetland and Stream Determination report for the Callaway Nuclear Plant dated June 19, 2009. This report was prepared by MACTEC to identify waters of the United States within the construction foot print for proposed unit 2. This report covers the area of the buried cable and identified two jurisdictional streams that would be crossed by the cable routing. The two streams were bored under to eliminate any stream impact and therefore eliminate the need for US Army Corps of Engineers project review.

The cable route was in close approximately of one of the 25 potentially significant archaeological sites that Ameren committed to preserving or performing additional surveys if impacted. The boundaries of the site were identified and the cable routing modified to avoid impacting the site in accordance with the Cultural Resource Management Plan.

This modification does not involve the possibility for discharge of oil into or upon the navigable waters of the U.S. The transformer was placed over a transformer pit capable of containing the oil should the transformer fail. In addition, petroleum use by the construction equipment will be controlled and contained to accepted equipment standards.

The evaluation concluded that Installation of the alternate emergency power source did not involve an unreviewed environmental question.

MP 10-0038, Revision 1- New Diesel Powered Emergency Generator Facility Description of Modification:

Modification MP 10-0038, revision 0, installed a new diesel powered emergency generator facility south of the existing COOP substation on Highway CC. This modification includes the installation of four (4) diesel power generators and associated support equipment to operate and connect the generators to the 138kV line installed from the COOP substation to the plant. The facility provides permanent alternate emergency power sources to Callaway if the COOP substation is unavailable. The new generators will each be 2 MWe skid mounted diesel powered units certified to meet Tier 2 nonroad engine emission standards. Mounted under each diesel generator skid is a 3500 gallon self-contained fuel oil tank with a secondary containment.

Evaluation of Change:

Both the Callaway Plant ER and FES-OL were reviewed, as part of this evaluation for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated. For this modification, there were some impacts due to the construction of the new diesel generator facility. The construction footprint for the facility is less than one acre and does not require a land disturbance I storm water permit from Missouri Department of Natural Resources (MDNR).

However, impacts from grading, excavation and construction activities will be managed using the appropriate best management practices (BMPs) and the areas that are temporarily impacted will be returned to their original state after completion of the project. After construction of this facility, the rainwater runoff coefficient will increase from approximately 0.20 to 0.77. Although there will be an increase in runoff from the facility, the facility is less than one acre and the runoff will be sheet flow from the site into the surrounding farm field, and will have no adverse effect on current storm water drainage.

The reviewed of the project area did not identify any jurisdictional wetland or stream that would be affected by this project. Although the installation of the facility will remove some land from its original use, the area affected is less than one acre and would not significantly change the use of the area. Review of the Callaway Cultural Resource Management Plan did not identify any cultural resource site within the area of the project.

The use of the new diesel generators will increase air emissions that will result in an increased discharge of pollutants. Ameren Environmental Services Air Group has applied for and received from the Missouri DNR- Air Pollution Control Program a Permit to Construct- Permit Number: 102010-005 to construct and operate these new diesel generators. This permit does contain operating conditions that have to be complied with during operation of the diesel generators. The four diesel generators will each contain a maximum of 3500 gallons of fuel oil. The fuel oil tanks are designed with a secondary containment and are located under each diesel generator skid. Therefore, fuel oil from these units is unlikely to reach the environment. If any leakage of fuel oil occurs, it would be absorbed into the gravel and structural fill located around and beneath the equipment. It is highly unlikely that any oil would reach the drainage ditch.

Based on the issuance of the Air Permit and this evaluation it was concluded that the installation of the New Diesel Powered Emergency Generator Facility does not involve an unreviewed environmental question.
