1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2010 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 2010 is included in Part II of this report.

Enclosure to ULNRC-05785 Page 8 of 115 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 2010 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 2010 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.

2 Enclosure to ULNRC-05785 Page 9 of 115 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; 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, 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 zlnc-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 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 Enclosure to ULNRC-05785 Page 10 of 115 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 Tables 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 during the grazing season (April 15 through December 15) 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.

Soybean collections were added to the program in 2008. The sites (FC-1 through FC-4) are located on Ameren property, traversed by the discharge pipeline.

The samples are collected at harvest and analyzed for tritium and gamma emitting isotopes.

The waterborne pathway is monitored by sampling surface water, groundwater and drinking water, and bottom and shoreline sediments.

Samples are analyzed for tritium and 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 ). Twelve onsite surface water ponds are sampled semiannually and analyzed for tritium and emitting isotopes.

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-05785 Page I I of I I5 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 (V3, W1 ). The samples are analyzed for gamma-emitting isotopes.

Results of supplemental soil testing 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 dally collections by automatic river sampler at two locations, S01 and S02. The sampler at S01 was 100% operable in 2010; down-time approximately 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . The sampler at S02 was 91% operable through November 27, 2010; down-time approximately 690 hours0.00799 days 0.192 hours 0.00114 weeks 2.62545e-4 months . The sampler at S02 was taken out of service from November 27 through December 31, 2010 to replace obsolete system controls with a programmable logic controller.

This should improve system reliability by making the sampler less susceptible to short term power outages. (2)Ground Water: No ground water was available from monitoring wells U1 MW-28, MW-939 and MW-940. The wells were added to the program in the fourth quarter, 2010, but were dry upon initial sam piing. (3) Vegetation:

No vegetation samples were available from station V-15 for the June 22, 2010 collection, due to damage from wild animals. Vegetation samples were not available from station V-14 for the August 17, 2010 collection.

The garden was not producing.

(4) Food Crops: Soybean samples were not available for harvest from two locations, FC-1, FC-2. No crops were planted in those locations for 201 0. (5) Direct Radiation:

The TLD for location IDM-36 was missing for the 2nd quarter, 2010. TLDs for locations IDM-17, IDM-30A and IDM-38 were missing for the 3rd quarter, 2010. The TLDs were replaced.

Vandalism is suspected.

5 Enclosure to ULNRC-05785 Page 12 of 115 3.4 Laboratory Procedures The lodine-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 iodlne-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 Framatome.

The laboratory meets the requirements of Reg. Guide 4.13 and is accredited by NVLAP for photon, beta and photon/beta mixture categories, in accordance with ANSI N 13.11. 3.5 Program Modifications Milk sampling was discontinued at location M-1 0 in 2010. The property owner declined to continue participation in the program. Two TLD sites, IDM-22a and IDM-32a, were relocated slightly, due to access issues with the property owners. Eighteen new monitoring wells were added to the program in 2010. Fourteen of the new wells ( U1MW-17, U1MW-18, U1MW-19, U1MW-20, U1MW-21, U1MW-22, U1MW-23, U1MW-24, U1MW-25, U1MW-26, U1MW-27, U1MW-28, U1MW-29 and U1MW-30) are located in the discharge pipeline corridor, downgradient of the discharge pipeline.

Four additional new wells (MW-938, MW-939, MW-940, MW-941) monitor the plant peninsula area. The samples are collected quarterly and analyzed for tritium and gamma emitting isotopes.

6 Enclosure to ULNRC-05785 Page 13 of 115 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 2010, 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 15, 2010. 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.

These parameters were determined using a combination of map position, aerial photography, and 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 2010. No irrigation or drinking water intakes were found within 10 river miles downstream of the plant discharge point. 7 Enclosure to ULNRC-05785 Page 14 of 115 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 2010 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 There were no reported nuclear accidents or atmospheric nuclear testing done in 201 0. 4.2 Program Findings Results obtained show background levels of radioactivity in environmental samples collected beyond the plant property boundary in 2010. 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.

In 136 of the 260 samples tested, Beryllium-?

measured above an LLD value of 0.16 pCi/m 3 , with an average activity of 0.23 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 There was no 1-131 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 lTLDs) Forty-three TLDs were placed in 16 sectors around the Callaway site. Measurements from forty indicator locations averaged 15.4 mrem /quarter and the three control locations averaged 14.4 mrem/quarter.

The readings ranged from 10.5 to 17.4 mrem /quarter, with the highest from the location CA-IDM-40, averaging 16.7mrem /quarter.

The differences are statistically insignificant.

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

8 Enclosure to ULNRC-05785 Page 15 of 115 4.2 Program Findings (continued)

Milk lodine-131 results were below the detection limit of 0.5 pCI/L In all samples. No gamma-emitting isotopes, except naturally occurring potassium-40, were detected in any milk samples. This is consistent with the finding of the National Center for Radiological Health that most radiocontaminants in feed do not find their way into milk due to the selective metabolism of the cow. The common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health, 1968). In summary, milk data for 2010 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 57.0 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, 2010, and analyzed for tritium and gamma-emitting isotopes.

No tritium activity was measured above a detection level of 164 pCi/L in any of the samples. Potassium-40 activity ranged from 13,503 -14,225 pCi/kg wet weight and averaged 13,937 pCi/kg wet weight. All other gamma-emitting isotopes measured below detection limits. No effect from the plant operation is indicated.

Fish 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 (2,675and 2,852 pCi/kg wet, respectively).

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 328 and 123 pCI/kg dry, respectively.

The cesium-137 activity is similar to or less than levels observed from 1999 through 2009, these levels are generally attributable to deposition of fallout from previous decades. Naturally-occurring potassium-40 averaged 11435 pCi/kg dry weight. Analysis results for soil samples in 2010 were consistent with previously accumulated data and no plant operational effects were identified.

9 Enclosure to ULNRC-05785 Page 16 of 115 4.2 Program Findings (continued)

Surtace Water Slight tritium activity above the detection limit of 172 pCi/L was observed in four of the thirteen samples collected from the downstream location S-02. Measurements averaged 221 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. No tritium activity was measured above a detection level of 188 pCi/L in any of the samples. Gamma-emitting isotopes measured below detection limits. 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 164 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-eight additional indicator ground water locations, on-site and along the discharge pipeline, are included in the REMP. Tritium activity (above a detection limit of 189 pCi/L) was detected in 52 of the 211 samples tested, with an average activity of 299 pCi/L. The highest concentrations were observed from samples taken at location MW-19, with an average activity of 528 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 low level tritium activity observed in wells MW-014, MW-017 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 Enclosure to ULNRC-05785 Page 17 of 115 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, 2010, and analyzed for gamma-emitting isotopes.

Potasslum-40 activity ranged from 12,998 to 14,786 pCi/kg dry weight and averaged 14,027 pCi/kg dry weight. Shoreline sediments were also collected in April and October, 2010. Trace Cs-137 activity was detected in one of two control samples at a concentration of 30.2 pCi/kg dry weight. Potasslum-40 activity ranged from 13,237 to 14,513 pCi/kg dry weight and averaged 14,039 pCi/kg dry weight. Potassium-40 is a naturally occurring isotope. 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.

NOTE: APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS 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 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, 2010 through December, 2010 Enclosure to ULNRC-05785 Page 46 of 115 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 radionuclldes 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 lntercomparlson 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. A1 Enclosure to ULNRC-05785 Page 47 of 115 Attachment A ACCEPTANCE CRITERIA FOR "SPIKED" SAMPLES LABORATORY PRECISION:

The interpretations and conclusions regarding these plant changes along with a description of the change and activity are presented below.

Enclosure to ULNRC-05785 Page 68 of 115 MP 08*0031. partial Makeup/Discharge Pipe Replacement Description of Modification:

Modification MP 08-0031 replaced several sections of plant piping including a section of the plant makeup line from Manhole 86-4 (butterfly valve VOB1001) to a flanged tie-in located at the circulating/service water pump house and a section of the blowdown pipe near Manhole 86-2 to a flanged tie-in located at the circulating/service water pump house. The existing Techite piping was replaced with high-density polyethylene (HOPE) which is a more robust material.

The old 72" diameter makeup pipe that splits Into two 54" diameter pipes was replaced with one 54" diameter HOPE pipe from Manhole 86-4 to the eire/service water pump house. The other 54" pipe was abandoned In place. The tie-In for the existing 18" blowdown piping from Manhole 86-2 to the eire/service water pump house was completed using 18" diameter HOPE. The tie-In of the new blowdown piping, Installed under MP 07-0012, to Manhole 86-2 was completed using 30" diameter HOPE. A new 12" diameter HOPE drain line was also Installed from the low point of the new 54" makeup pipe to Manhole 86-4A. In addition, this modification installed a new Manhole 86-2 to tie-In the new 30" and 18" blowdown lines as well as two 6" diameter stainless steel Radwaste liquid effluent lines. Existing Manholes 86-1, 86-2 and 86-3 were abandoned in place. Pipe penetrations into Manholes 86-2 and 86-3 were plugged and the interior surfaces of the manholes coated with Carboline elastomeric polyurethane to seal in any residual radioactive contamination.

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.

This did not change any plant liquid effluents or the concentration of effluents released.

The new section of blowdown piping was located within 20 feet of the existing blowdown line while the new section of makeup piping was located within about 50 feet of the existing makeup pipe. Approximately 1.25 acres of land was disturbed between the clearwell and the circulating/service water pump house to complete this modification.

The construction area was located within the owner-controlled area and was previously disturbed during plant construction.

Storm water runoff was controlled utilizing Best Management Practices and the construction area drained to the NPDES permitted Outfall #011. Previous cultural resource surveys of this area did not identify any significant archaeological sites. The evaluation concluded that Installation of the replacement sections of the makeup and blowdown piping did not involve an unreviewed environmental question.

New Treatment for WTP Clarifiers

& Cooling Tower to Prevent Algae Growth Description of Modification; This RFR approves the use of a new chemical additive at Callaway Plant for algae control In the cooling tower and the water treatment plant clarifiers.

BULAB 6060 (4% aqueous dispersion of 2-chloro-4,6 dialkylamino-s triazine, CAS #5915-41-3)

Is utilized in addition to sodium hypochlorite (currently used) to inhibit the growth of algae in these plant systems. BULAB 6060 is applied to the water treatment plant clarifiers approximately three times per week for a period of six months per year (April through October) at a dosage up to 4 ppm as product at the same times that sodium hypochlorite is applied. The addition of BULAB 6060 works synergistically to allow the sodium hypochlorite to be more effective.

The use of this product is also expected to reduce the amount of hypochlorite currently being added to the clarifiers by up to 50%. The cooling tower bypass (Outfall 01 6) is isolated during this treatment for a minimum of six hours and placed back in service only after the total residual chlorine (TRC) concentration is within limits for discharge.

BULAB 6060 is also added to the circulating/service water system for up to one hour per day up to a maximum concentration of 5 ppm as product to prevent algae growth in the cooling tower basin and cooling tower fill material.

The one hour per day addition occurs during the daily chlorination approximately five times during the period from June through September.

The use of triazine (BULAB 6060) for both applications results in discharges from Outfall 002, cooling tower blowdown and very infrequent discharges from Outfall 016, cooling tower bypass. The highest concentration expected In the cooling tower basin or the cooling tower bypass is 5 ppm as product. This concentration of BULAB 6060 should not have any significant impact on the quality of the receiving water as significant mixing occurs at the point of discharge to the Missouri River providing a low aquatic toxicity In the Missouri River. Evaluation of Change: As part of the Final Environmental Evaluation, both the ER and FE S-OL were reviewed for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated.

No environmental impacts were identified.

BULAB 6060 is a non-toxic algal control agent used intermittently with sodium hypochlorite.

The cooling tower bypass is isolated during treatment of the water treatment plant clarifiers for a minimum of 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months after each addition of BULAB 6060. This product is also utilized in the circulating/service water system for up to one hour per day during the summer months. Some product is discharged in the cooling tower blowdown (Outfall 002) and the cooling tower bypass (Outfall 016), however, the discharge Is diluted by other outfalls and the significant mixing that occurs at the point of discharge to the Missouri River. The Missouri Department of Natural Resources was informed in writing of the use of this new product at Callaway on November 24, 2009, as this product was not included in the current NPDES Permit or the most recent permit reapplication.

On April 14, 2010, the Missouri DNR Issued a minor revision to the NPDES Permit (M0-0098001

). The minor permit modification changed the Whole Effluent Toxicity (WET) Acute and Chronic Testing to acknowledge the periodic and potential discharge of the algaecide BULAB 6060 from Outfall 002 and/or Outfall 016. The new NPDES permit was Issued April 14, 2010. Based on the new NPDES permit and this evaluation, it was determined that the use of this new product to inhibit the growth of algae does not Involve an unrevlewed environmental question.

Enclosure to ULNRC-05785 Page 70 of 115 MP 10-0023. Temporary Diesel Generators Description of Modification:

This modification MP 10-0023 installed five large temporary backup diesel generators, five transformers and associated equipment on the plant south side of the ultimate heat sink (UHS) cooling tower. The temporary diesel generators provided 2 MW per unit (1 0 MW total) to supplement the two permanent emergency diesel generators (EDGs) In the event of an EDG failure. The five diesel generators are portable trailer mounted units (each 8 X 40 ft) parked on a structurally sound gravel parking area. The diesel generators each contain a 1250 gallon double-walled self-contained fuel oil tank. Five 12,000 pound transformers were installed on concrete pads adjacent to each of the five diesel generators.

Each of the transformers contains 387 gallons of oil with no secondary containment device. This modification included some land disturbance (grading and fill replacement) in the area for placement of this heavy equipment.

In addition, some minor trenching was performed to run the conduit for completing the tie in to XNB02. Initially, this equipment was expected to remain on site for 18-20 months or longer if required.

The temporary generator and associated equipment was removed from the site in April 2011. 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.

The fuel oil tanks are double walled and are contained within the trailer-mounted unit. Based on design, fuel oil from these units is unlikely to reach the environment.

The temporary diesel generators meet the requirements of NSPS for new compression Ignition reciprocating Internal combustion engines (CI RICE) under 40 CFR 60 Subgroup 1111. The use of the temporary diesel generators was expected to increase air emissions and result In an Increased discharge of pollutants.

Ameren applied to the Missouri DNR Air Pollution Control Program for a permit to construct and operate these new temporary diesel generators and the Air Permit issued on June 4, 2010. In addition, any leak or spill of transformer oil would be absorbed into the gravel and structural fill located around and beneath this equipment.

It is highly unlikely that any oil would reach the storm water ditch that is located approximately 100 feet from the transformers.

The construction area was located within the owner-controlled area and was previously disturbed during plant construction.

Based on the issuance of the Air Permit and this evaluation it was concluded that the installation of the temporary diesel generators and associated equipment does not involve an unreviewed environmental question.

Enclosure to ULNRC-05785 Page 71 of 115 MP 10-0032. Non-Safety Auxiliary Feed Pump Description of Modification:

This modification is for the installation of a non-safety auxiliary feedwater pump, including piping, valves, electrical power, and instrumentation and controls.

The suction, discharge and recirculation piping for the new pump connect to the plant systems using existing system connections and isolation valves. A new transformer containing 488 gallons of non-PCB transformer oil with no secondary containment device was installed west of the turbine building near the southwest stairwell.

The electrical power for the pump is supplied by the alternate emergency power system. The electrical power for the transformer heaters is supplied by existing electrical distribution panels. Evaluation of Change: Since the non-safety auxiliary feedwater pump and associate equipment was installed In an existing plant building, this equipment was excluded from this evaluation.

This evaluation looked at the transformer installed on a flat area near the turbine building that is part of the power block seismic backfill.

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 environmental impacts were identified.

In addition, any leakage of oil from the transformer would be contained in or absorbed by the granular fill around the transformer.

It is highly unlikely that any oil leakage or spillage would reach the storm water drainage or navigable waters of the US. The evaluation concluded that the installation of this equipment does not involve an unreviewed environmental question.
