1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2013 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 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 2013 is included in Part II of this 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 herein described.

Results for the year 2013 are summarized and discussed.

For the year, the Callaway Energy Center was operated in compliance with Off Site Dose Calculation Manual (ODCM) and Radiological Effluent Controls (REC) requirements. Comparison of results for 2013 show no significant differences to the historical data. 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.

Enclosure to ULNRC-06111 Page 9 of 106 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. 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 Energy Center 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 Energy Center, 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-7, 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.

Enclosure to ULNRC-06111 Page 10 of 106 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, 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.

Feed crops (soybeans, sorghum, corn) 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. Feed crops are grown for animal feed and not for human consumption.

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 ten 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.

4

Enclosure to ULNRC-06111 Page 11 of 106 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.

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. Sampler down-time at S01 was approximately 28.7 days; the sampler at S02 was out-of service approximately 21.9 days. During sampler downtimes, composites of daily grab samples were prepared and submitted for analysis.

(2) Ground Water:

No ground water samples were available from monitoring well U1MW-28 for the first, third and fourth quarters, 2013. A second quarter sample was collected and analyzed for tritium and gamma emitting isotopes. Sampling has been intermittent since installation in 2010. The well is normally dry, since the area is rocky, with only a shallow overburden of clay. U1MW-28 was installed specifically to monitor for leakage from the single vacuum breaker on the discharge pipeline.

(3) Milk:

A scheduled bimonthly collection of milk from location M-9 was not available April 22, 2013, the cow was not yet on pasture.

(4) Broadleaf Vegetation:

Edible broadleaf vegetation, collected at three of the five area gardens was available for harvest from June through October, 2013. Location V-16 did not produce until July, and location V-17 reached the end of its season with the September sampling. Missing samples during the periods when the gardens were producing are listed in Table 2.0.

The growing season is defined as April 1 through October 31 (ref: Hammer, Gregory R.). A vegetation sample unavailable after October 31 is not considered a missed sample.

5

Enclosure to ULNRC-06111 Page 12 of 106 Program Execution (continued)

(5) Air Iodine and Particulates 3

A partial air particulate / air iodine sample (219 m ) was collected at location A-1 for the week ending 02/28/13. A power interruption resulted in a reduced run-time of approximately 27 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br />. (This is documented in the Callaway corrective action program as CAR 201301416.)

The air sampler at station A-9 failed during the week ending 05/23/13. The sampler pump was replaced. (This is documented in the Callaway corrective action program as CAR 201304219)

No sample was available from air sampler station B-3 for the week ending 08/01/13. The station lost power after an estimated run-time of 66.8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. After exchange of the particulate filters and charcoal cartridges, the pump was restarted. (This is documented in the Callaway corrective action program as CAR 201306073)

(6) Direct Radiation:

From March 12 through April 5, 2013, first quarter dosimeters from location IDM-44 were missing, due to a utility pole change out (This is documented in the Callaway corrective action program as CAR 201302384). The TLDs were recovered and read, but do not reflect the true exposure for the location during the missing weeks.

TLD and fade dosimeters placed at location IDM-32A were missing for the 2nd quarter, 2013. The TLDs were replaced. Vandalism is suspected. (This is documented in the Callaway corrective action program as CAR 201305426.)

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 at the laboratory 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, 2012). 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.

Enclosure to ULNRC-06111 Page 13 of 106 3.5 Program Modifications

1. For the 2013 growing season, vegetation sampling location V-17 replaced station V-14, due to a history of poor performance.

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 2013, the survey was conducted within a five mile canvassing radius of the Callaway Energy Center. The location of the nearest resident, milking animal, and broadleaf vegetation 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 30, 2013. 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, determined by a Global Positioning System (GPS) receiver.

The census includes identification of drinking water wells along Mud Creek, Logan Creek and along the discharge pipeline corridor. No new drinking water wells were identified in 2013.

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

7

Enclosure to ULNRC-06111 Page 14 of 106 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 2013 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 There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 2013. The Fukushima Daiichi nuclear accident occurred March 11, 2011.

There were no reported atmospheric nuclear tests in 2013. The last reported atmospheric test was conducted on October 16, 1980 by the Peoples Republic of China.

4.2 Program Findings Results obtained show background levels of radioactivity in environmental samples collected beyond the plant property boundary in 2013. 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 (A1, 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.

3 In 84 of the 258 samples tested, Beryllium-7 measured above an LLD value of 0.16 pCi/m , with 3

an average activity of 0.22 pCi/m . Beryllium-7 is produced continuously in the upper atmosphere by cosmic radiation. No gamma emitting isotopes of plant origin were identified.

Airborne Iodine There was no I-131 activity detected in weekly collections of charcoal canister samples. All 3

measurements were below the required lower limit of detection (LLD) of 0.070 pCi/m .

Direct Radiation (TLDs)

Forty-three TLDs were placed in 16 sectors around the Callaway site. Measurements from forty indicator locations averaged 16.1 mrem/quarter and the three control locations averaged 14.8 mrem/quarter. Readings ranged from 10.9 to 19.3 mrem /quarter, with the highest from the control location CA-IDM-11A, averaging 17.7 mrem/quarter. The differences are statistically insignificant.

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

8

Enclosure to ULNRC-06111 Page 15 of 106 4.2 Program Findings (continued)

Milk Iodine-131 results were below the detection limit of 0.5 pCi/L in all samples.

No gamma-emitting isotopes, excepting naturally occurring potassium-40, were detected in milk.

Average potassium-40 activity measured 1135 pCi/L and ranged from 921-1467 pCi/L.

In summary, milk data for 2013 show no radiological effects of plant operation.

Vegetation There was no I-131 activity detected in broadleaf vegetation samples. Measurements were below an LLD level of 46.3 pCi/kg wet weight in all samples.

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

Non-Food Crops Soybeans and sorghum samples were collected in October, 2013, and analyzed for tritium and gamma-emitting isotopes.

No tritium activity was measured above a detection level of 154 pCi/L in any of the samples.

Potassium-40 activity varied dependent on sample type. Sorghum samples averaged 3,401 pCi/kgwet, versus soybeans with an average of 16,036 pCi/kgwet. All other gamma-emitting isotopes measured below detection limits.

No effect from the plant operation is indicated.

Fish Edible portions of fish were analyzed by gamma spectroscopy. The potassium-40 averages were almost identical at indicator and control locations (2,930 and 2,901 pCi/kg wet, respectively).All other gamma-emitting isotopes measured below detection limits.

No plant effect on the fish population is indicated.

Soil Cesium-137 activity was detected at both indicator and control locations, at average concentrations of 331 and 98 pCi/kg dry, respectively. The cesium-137 activity is similar to or less than levels observed from 1999 through 2012, these levels are generally attributable to the deposition of fallout from previous decades.

Naturally-occurring potassium-40 averaged 10,464 pCi/kg dry weight.

Analysis results for soil samples in 2013 were consistent with previously accumulated data and no plant operational effects were identified.

4.2 Program Findings (continued) 9

Enclosure to ULNRC-06111 Page 16 of 106 Surface Water Low-level tritium activity above a detection limit of 188 pCi/L was observed in four of the twelve samples collected from the downstream location S-02. The measurements averaged 596 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, ten onsite surface water locations (SWA) have been included in the permanent REMP. There was no tritium activity measured above a detection level of 157 pCi/L in any of the samples. In previous years, low-level tritium activity detected was believed to be the result of washout from gaseous effluents.

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 150 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 indicated.

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 165 pCi/L) was detected in 75 of the 285 samples tested, with an average activity of 278 pCi/L. The highest concentrations were measured at OW-5 (UHS pond berm), with an average activity of 340 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 in wells OW-4 and OW-5 is believed to be historical tritium due to river water recycle of tritium in liquid effluents. Tritium activity in the remainder of these wells is believed to be the result of washout from gaseous effluents.

The low level tritium activity observed in wells MW-014, MW-018 and MW-019 is due to residual low level contamination of the area down gradient from manholes 5 and 6B. 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 ARVs was secured in 2007, and the pipeline was replaced in 2008. The new discharge pipeline has no ARVs 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. The contamination is being remediated by monitored natural attenuation. There are no active leaks.

10

Enclosure to ULNRC-06111 Page 17 of 106 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 May and October, 2013, and analyzed for gamma-emitting isotopes. A low level of cesium-137 was detected in one of the two control samples at a concentration of 30 pCi/kg dry weight, but measured below detection limits at the indicator location. Potassium-40 activity ranged from 11,187 to 13,456 pCi/kg dry weight and averaged 12,528 pCi/kg dry weight.

Shoreline sediments were also collected in May and October, 2013. No cesium-137 activity was detected at either the control or indicator locations. Potassium-40 activity ranged from 12,222 to 13,943 pCi/kg dry weight and averaged 13,174 pCi/kg dry weight.

Potassium-40 is a naturally occurring isotope. The slight cesium-137 activity observed is indicative of the influence of fallout deposition. All other gamma-emitting isotopes were below detection limits. No effect from the plant operation is indicated.

Enclosure to ULNRC-06111 Page 40 of 106 APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison 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, 2013

Enclosure to ULNRC-06111 Page 41 of 106 Appendix A Interlaboratory Comparison Program 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.

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 Intercomparison 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.

Enclosure to ULNRC-06111 Page 61 of 106 APPENDIX B. DATA REPORTING CONVENTIONS 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 = 2 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 4.66 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 x2 +/- s2 Reported result: x +/- s; where x = (1/2) (x1 + x2) and s = (1/2) s12 + s 22 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 x and standard deviation s of a set of n numbers x1, x2 . . .

xn are defined as follows:

1 (x- x )2 x =n x s= n-1 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.

Enclosure to ULNRC-06111 Page 62 of 106 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 2013.

2.0. Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2013.

3.0. EPP Non-compliances During 2013, there were no non-compliances with the EPP.

4.0. Nonroutine Reports There were no nonroutine reports submitted in accordance with the EPP, Section 5.4.2 in 2013.

5.0. Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, operation, tests or experiments installed during 2013, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2013, two 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 on the following pages.

Enclosure to ULNRC-06111 Page 63 of 106 RFR 201300712 - Use of alpha-Ketoglutaric Acid (AKGA) for Neutralizing Hydrazine Description of Change:

Engineering evaluation RFR 201300712 approved the use of a new chemical, alpha-Ketoglutaric Acid (AKGA), for neutralization of hydrazine in liquid radwaste prior to discharge from NPDES Outfall 001.

Neutralization of hydrazine is infrequent and normally only necessary during and following extended outages when secondary systems are placed in wet layup and then later drained for maintenance or plant startup. In the past, Callaway used sodium hypochlorite to consume hydrazine in liquid radwaste prior to discharge. AKGA is much less hazardous to plant personnel than sodium hypochlorite, is much less toxic to the environment, and AKGA is also more efficient at neutralizing hydrazine.

Evaluation of Change:

Callaways NPDES Permit MO-0098001 requires Missouri Department of Natural Resources notification for significant changes such as new or different substances being discharged. AKGA was not identified in the most recent NPDES Permit reapplication or in the current NPDES Permit.

Therefore the Missouri Department of Natural Resources (DNR) was notified in writing of this change indicating there would be no adverse impact on the quality of the receiving waters from the use of this product as planned.

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 adverse environmental impacts were identified. This change results in lower toxicity to the receiving stream as well as AKGA being less hazardous to plant personnel who handle this product. Ameren received a letter from Missouri DNR stating they concur with Amerens evaluation for the use of AKGA to consume hydrazine in liquid radwaste (NPDES Outfall 001) prior to discharge.

This evaluation concluded that use of AKGA for neutralization of hydrazine in liquid radwaste prior to discharge does not involve an un-reviewed environmental question.

Enclosure to ULNRC-06111 Page 64 of 106 MP 11-0002 - Meteorological Tower Communication Upgrade Description of Change:

Modification MP 11-0002 includes changes to provide a more reliable and secure communications path between the Meteorological Tower and Callaway Plant by replacing the current wireless based communications with a fiber optic based system. This modification includes the installation of an underground fiber optic cable from the meteorological tower to the control building. The fiber optic cable run required some land disturbance including crossing two jurisdictional streams and a county road.

Evaluation of Change:

The fiber optic cable was installed using linear construction that consisted of a trench two feet or less in width. The two jurisdictional stream crossings were bored under to eliminate any stream impact and therefore eliminated the need for review by the US Army Corps of Engineers. Missouri State Regulations allow an exemption for storm water permits for this type of construction. Therefore construction for this modification did not require that Missouri DNR be contacted to obtain a land disturbance permit or a storm water permit. All construction activities including trenching required utilization of Best Management Practices for minimizing the impact of solids runoff to storm water.

Following completion of all work, the disturbed areas were restored to pre-construction conditions including grading, seeding and mulching as needed.

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 adverse environmental impacts were identified. Missouri DNR approval or permits were not required. This modification was completed with no adverse environmental impacts with all areas disturbed for trenching returned to pre-construction conditions. All trenching and land disturbance work was completed using Best Management Practices to minimize impacts to storm water.

This evaluation concluded that this modification including excavation to run fiber optic cable from the meteorological tower to the control building does not involve an un-reviewed environmental question.
