1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2016 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 2016 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 described herein.

Results for the year 2016 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 (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.

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 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 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 five 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-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. 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-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 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 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). The surface water samples are composites of daily collections by automatic river samplers.

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 was collected monthly or quarterly from well locations both onsite and along the discharge pipeline. The samples were 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. The samples were analyzed for tritium and gamma-emitting isotopes.

4

3.2 Program Description(continued)

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.

The direct ambient gamma radiation pathway is also considered. This exposure is monitored by thermoluminescent dosimeters (TLDs) at forty-eight locations in and around the Callaway site.

The TLDs are placed in 16 sectors around the plant as specified in the ODCM-RECS. Five of the 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, W1) 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) Surface Water:

The sampler at S01 was out of service 8 days; the sampler at S02 was out-of service 32 days.

(2) Ground Water:

No groundwater was available from location 937B for the 1/14/16 scheduled collection due to construction in the area limiting safe access to the well.

(3) Drinking Water:

No drinking water sample was available at location DWA-05 for the 2/2/16 scheduled collection. The provider residence was unoccupied on the scheduled collection date. The new owner subsequently joined program.

(4) Broadleaf Vegetation:

Edible broadleaf vegetation, collected at the four area gardens was available for harvest from May through October, 2016 with the following exceptions: Location V-9 was unavailable in May (CR201604623) and August (Conditions too wet for planting CR201606827). Locations V-11 and V-16 started producing in May but were done producing in September. See Table 5.5.

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

(5) Inedible Crops:

Inedible crops were not collected at location FC-1 during the 2016 collection due to the field not being planted.(CR201607652)

(6) Direct Radiation:

The second quarter TLD at location IDM-33 was found missing (CR201606360).

3.3 Program Execution (continued)

(7) Airborne Particulates and Iodine.

Air sample station B-3 was permanently shut down on 12/28/16 and the sampling equipment was relocated to new location A-10. The program had one less than the required number of air sampling stations during this seven day transitional period. (CR201700071).

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.

3.5 Program Modifications The drinking water sample at location CA-DWA-05 was added back into the program. This location was previously deleted when the property was sold and left vacant for several months.

The location was added back to the program after the new owners were located and agreed to participate in the sampling program (CR201601894).

Leafy green vegetables at location CA-FPL-V-17 were deleted from the program when the provider decided to discontinue broadleaf vegetation in his garden. Location CA-FPL-V-11 previously designated as a backup sample was re-designated as a primary sample and an ODCM required sample(CR201601894)

Air sampler station CA-APT/AIO-B3 was deleted and air sampler stations CA-APT/AIO-A10 and CA-APT/AIO-A11 were added as a result of the re-evaluation of long-term dispersion parameters.

Refer to HPCI 1506, Evaluation of Air Sampler Locations with Respect to the Recalculated Dispersion Parameters.

A neutron sensitive TLD was added to the program at location IDM-60N which is collocated with TLD IDM-60. (CR201604129).

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 2016, the survey was conducted within a five mile canvassing radius of the Callaway Energy Center. The location of the nearest resident, nearest milk animal, and nearest garden of greater than 50 square meters producing broadleaf vegetation was identified by aerial photography and 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. Residences in the vicinity of the plant were surveyed in person and by telephone.

The field inspection of the sectors was conducted on September 23, 2016. 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.

No new well water sources were identified along the Callaway Energy Center pipeline corridor. No irrigation uses of the 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 (10) 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 2016 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 2016. 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 2016.

4.2 Program Findings Airborne Particulates and Iodine No gamma emitting isotopes were identified other than naturally occurring Be-7.

There was no I-131 activity detected in any of the charcoal canister samples.

Air sampling for 2016 indicates no radiological effects of plant operation.

Direct Radiation (TLDs)

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

Measurements from forty indicator locations averaged 15.6 mrem/quarter and the three control locations averaged 14.8 mrem/quarter. Readings ranged from 11.1 to 18.7 mrem /quarter, with the highest from the indicator location CA-IDM-11A, averaging 17.7 mrem/quarter. The differences are statistically insignificant. The TLD readings were consistent with the results for the years 2000 through 2015 as detailed in table 5.7.

Four 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 measureable neutron dose and there was no effect from the ISFSI.

Milk There are no milk indicator stations. No iodine-131 was detected in samples from the control station. No gamma-emitting isotopes, with the exception of naturally occurring potassium-40, were detected in milk. Milk data for 2016 show no radiological effects of plant operation.

Broadleaf Vegetation There was no I-131 activity detected in broadleaf vegetation samples. No gamma-emitting isotopes were detected in broadleaf vegetation samples excepting naturally occurring potassium-

40. Vegetation data for 2016 show no radiological effects of plant operation.

Non-Food Crops Soybean samples were analyzed for tritium and gamma-emitting isotopes. No tritium activity was detected. No gamma-emitting isotopes, excepting naturally occurring potassium-40, were detected in non-food crops.

Fish Edible portions of fish were analyzed by gamma spectroscopy. No gamma-emitting isotopes, excepting 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 264 pCi/kg dry. 306 pCi/kg dry was the average activity for the ten of fourteen positive indicator locations and 108 pCi/kg dry was the average activity for the three of four positive control locations. The cesium-137 activity is consistent with levels observed from 1999 through 2015; these levels are attributable to the deposition of fallout from previous decades.

Surface Water Low level tritium was detected in two of the twelve samples collected at the downstream location S02 at an average concentration of 304 pCi/L. There was no tritium detected in the remaining ten samples from S02. No gamma-emitting isotopes were detected.

Surface Water, Ponds Eighteen pond samples were analyzed for 2016. No tritium activity or gamma activity was detected.

Drinking Water Wells (potable water)

Quarterly samples from fourteen 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-15 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 2014 LSI (the 2014 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 2015 and continued to decrease in 2016. Tritium activity was detected in 20 of 29 samples from these wells. The highest concentration was measured in MW-31 which peaked at 4,448 pCi/L in October. By years end, the concentration in MW-31 had fallen to 1,944 pCi/L. The average concentration among positive results for these wells was 1,072 pCi/L. 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, MW-018 and MW-019 is 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 of this area since then. The existing contamination is being remediated by monitored natural attenuation.

There are no active leaks and the results are consistent with 2015..

9

Sediments Samples of shoreline and bottom sediments were analyzed for gamma-emitting isotopes.

Cesium-137 was detected in one of the two bottom sediment control samples at a concentration of 74 pCi/kg dry weight, but measured below detection limits at both of the samples from the indicator location. Cesium-137 was also detected in one of the two shoreline sediment indicator samples at a measured concentration of 87 pCi/kg dry weight. These results are consistent with results from previous years. There were no other gamma-emitting isotopes excepting naturally occurring potassium-40 in any of the sediment samples.

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, 2016 through December, 2016

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 RAD PT Study Proficiency Testing 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 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. 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 MRAD PT Study Proficiency Testing 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.

Results are reported in units of Bq/kg (soil), Bq/L (water) or Bq/total sample (filters, vegetation).

b Laboratory codes as follows: MAW (water), MAAP (air filter), MASO (soil), MAVE (vegetation).

c 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.

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

e The laboratory properly identified the Sn-75 interfering peak in the vicinity of Co-57 and stated so in the comment field. MAPEP requires results to be reported as an activity with an uncertainty. Since the calculated uncertainty was less than the activity MAPEP interpreted the submitted result as a "false positive" resulting in a failure.

f Original analysis for Ni-63 failed.

g Reanalysis with a smaller aliquot resulted in acceptable results. An investigation is in process to identify better techniques for analyzing samples with complex matrices.

h MAPEP states that samples contain two fractions of Uranium; one that is soluble in concentrated HNO3 and HCl acid and one that is "fundamentally insoluble in these acids". They also state that HF treatment can not assure complete dissolution.

Results are consistent with measuring the soluble form.

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 and standard deviation s of a set of n numbers x1, x2 . . . xn are defined as follows:

1 (x- )2

=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.

Appendix C. NON-RADIOLOGICAL MONITORING PROGRAM 1.0. Introduction Union Electric Company Callaway Plant, d.b.a. Ameren Missouri Callaway Energy Center, 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 2016.

2.0. Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2016.

3.0. EPP Non-compliances During 2016, 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 2016.

5.0. Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, operation, tests or experiments installed during 2016, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2016, 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 15-0004, MP 15-0011, MP 15-0012, MP 13-0033 - Construction of the New Hardened Condensate Storage Tank Description of Change:

Modifications MP 15-0004, MP 15-0011, MP 15-0012, and MP 13-0033 include all construction and connections associated with the new Hardened Condensate Storage Tank (HCST) at Callaway Energy Center. This evaluation includes a review of the modification packages for this work as follows:

MP 15-0004 - Demolition and excavation work for placement of the new HCST MP 15-0011 - Construction of the foundation and underground piping MP 15-0012 - Construction of the tank, protective barrier system, valve house, & electrical MP 13-0033 - Connections to balance of plant equipment The 500,000 gallon stainless steel HCST was constructed on a 5.5 foot thick concrete slab, surrounded by a protective structural steel frame with a mesh barrier system to withstand a design basis accident. The foundation includes 64 drilled shafts to support the tank with 46 piers installed to a depth of 45 feet with a diameter of 3 feet and 18 piers installed to a depth of 60 feet. A 10 foot by 10 foot pipe trench was also excavated to route necessary stainless steel and fused high density polyethylene (HDPE) piping for connection to the existing secondary systems. Hydro excavation was used to remove backfill for the piping trench and connections to the current CST tunnel and turbine building.

The HCST will store demineralized water. All construction was completed within the protected area and near the existing power block.

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 new adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. All construction was completed within the protected area close to the power block in areas that had been previously disturbed. During construction storm water from this area was directed to two C-2

permanently permitted NPDES Outfalls. Therefore, this change does not involve an unreviewed environmental question and NRC approval is not required for this construction project.

MP 15-0018 - Replacement of Existing Transformer XPB218 at the Callaway Intake Facility Description of Change:

MP 15-0018 covers the replacement of the existing transformer XPB218 at the Callaway intake facility. The new transformer will contain 1667 gallons of refined mineral oil (approximately 588 gallons more than the original transformer). The original transformer was located above a permanent rock filled concrete pit to contain the total volume of oil should a leak develop. Rock will be removed from this pit to allow additional volume to contain the 1667 gallons should a leak occur in the new transformer. The containment pit will also contain a new double grating with an absorbent rock layer.

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 new adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. Although the replacement transformer will contain a larger volume on mineral oil, the concrete containment located under the transformer was redesigned to contain the entire volume of the new transformer. Therefore, should a leak develop, oil will be contained within the concrete pit and there is no increased risk of this oil being discharged to the Missouri River.

This change does not involve an unreviewed environmental question and NRC approval was not required.

RFR 201606690 - Use of BULAB 5011P a new Polymer/Coagulant Description of Change:

This change involves the use of BULAB 5011P (a new water soluble cationic polymer/coagulant) for removal of solids from makeup water withdrawn from the Missouri River.

This product will be utilized at the Water Treatment Plant (WTP) to treat makeup to plant raw water systems. Callaway was previously using BULAB 5013, Dimethyl Ammonium Chloride (DADMAC) a similar polymer/coagulant for solids removal. This change allows the use of either product or a blend of these two products to reduce solids carried to plant raw water systems.

As a result, it is expected that suspended solids will also be reduced in plant discharges from Outfalls 002 and 016. BULAB 5011P is a similar product to the current polymer but has a larger molecular weight. The new product is less toxic to aquatic life and will be used at the same treatment concentrations as previously used for BULAB 5013.

C-3

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 new adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. Missouri DNR approval or permit changes were not required as similar coagulants/ organic polymers were previously approved by the state. In addition, use of coagulants/organic polymers at the WTP was included in the last Callaway NPDES Permit re-application. Both products contain a similar water soluble cationic polymer which will be maintained at the same concentration range.

Aquatic toxicity data was reviewed for both BULAB products and BULAB 5011P was found to have a less toxic 48-hour LC50 and 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> LC50 than BULAB 5013. Therefore, use of BULAB 5011P for solids removal at the WTP should have no adverse effect on the environment.

This evaluation concluded that this change to utilize BULAB 5011P as a coagulant for solids removal at the WTP does not involve an unreviewed environmental question and NRC approval was not required.
