1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2008 for the AmerenUE 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 2008 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 Plant is herein described. Results for the year 2008 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 2008 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.

Attachment to ULNRC-05622 Page 9 of 132 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, barium-lanthanum-140, and cerium-141. These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the next group, manganese-54, cobalt-58 and-60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant effluents, but are not produced in significant quantities by nuclear detonation.

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

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

Attachment to ULNRC-05622 Page 10 of 132 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. Filters and cartridges are exchanged weekly.

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 through September) and monthly during the winter. 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.

This 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.

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

Monthly composite samples of surface water from the Missouri River are collected from one indicator location (S02) and from one control location (S01 ). The samples are analyzed for gross alpha, gross beta, tritium and gamma-emitting isotopes.

Ground water is collected quarterly from two deep aquifer sampling wells (F05 and F15), and two drinking water wells (001 and PW1 ). The samples are analyzed for gross beta, tritium, iodine-131 and gamma emitting isotopes.

An additional forty-five groundwater well (CA-WWA) and pond surface water (CA-SWA) locations, both onsite and along the discharge pipeline, Table 5.1, were added to the permanent program in 2008, and analyzed for tritium. An analysis for gamma-emitting isotopes is performed on select locations. Collections are scheduled quarterly or semi-annually.

Additional testing of ground and surface water samples is included in Part II, App. C.

Twenty-one drinking water wells (CA-DWA) Table 5.1, sampled quarterly, were added to the program in 2008. Analyses may include tritium and gamma-emitting isotopes.

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.

Attachment to ULNRC-05622 Page 11 of 132 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).The TLDs are placed at each location and are exchanged and analyzed quarterly.

To monitor the terrestrial environment, soil is collected annually from seven indicator locations (F2, PR3, F6, PR7, W2, W3, W4) and two control locations (V3, W1). The samples are analyzed for gross alpha, gross beta and gamma-emitting isotopes. Additional testing of soil and sediment samples is 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) Air Particulates I Air Iodine:

A partial sample was collected from air sampling stations A-8 (405 m3) for the week ending 07-03-08, the shorter run-time possibly due to storms in the area.

No viable air particulate I air iodine sample was available from location A-8 for the week ending 08-14-08. A power outage limited the sampler pump run-time to only 14 hours1.62037e-4 days 0.00389 hours 2.314815e-5 weeks 5.327e-6 months .

(2) Groundwater:

MW-009 was not sampled during the 3rd quarter, 2008. There was damage to the well from excavation activity during installation of a new discharge pipeline.

Excavation for a new essential service water pipeline blocked access to well #937E. No sample was available for the fourth quarter, 2008. Sampling of 937E will resume upon completion of the construction work.

(3)Milk:

A replacement for location M-08 was not available for the January, 2008 collection. A new provider (M-09) was added to the program in February, 2008.

Milk was not available from location M-1 0 for the September 23 collection and for the period from October 28 through December, 2008. The goats did not produce enough milk.

(4) Direct Radiation:

TLDs for locations IDM-45 and IDM-49 were missing for the 3rd quarter, 2008. Vandalism is suspected. The TLDs were replaced for the 4th quarter. The TLD at location IDM-1 0 was submerged during flooding in the 3rd quarter. The TLD appeared undamaged, but the data could be considered suspect.

(5) Fish:

Fish sampling for Spring, 2008 was delayed due to flood conditions on the Missouri River.

(6) Farm Crops:

Soybeans were not available for collection in 2008 from locations FC1, FC2, FC3 and FC4.

The fields were flooded prior to the harvest and the crops were destroyed.

5

Attachment to ULNRC-05622 Page 12 of 132 3.3 Program Execution (continued)

(7) Surface Water:

The automatic river sampler at location S02 became inoperable on 09/15/08 due to flooding of the equipment vault. The flooding also prohibited grab sampling. Grab sampling was resumed on 09/18/08.

(8) Vegetation:

Station V-15 did not provide samples during 2008. Sampling continued at Station V-14 as compensatory action.

(9) The ODCM was revised effective July 8, 2008 to require gamma spectroscopic analysis on each particulate air sample (REMP airborne sampling stations A 1, A?, AS, A9, and 83).

Plant procedure HTP-ZZ-071 01, Appendix A, was revised to reflect the changes to the ODCM, however, the laboratory was not notified, and the required gamma spectroscopic analyses were not performed. Affected samples are those airborne particulate filters collected July 10, 2008 through January 1, 2009. (CAR 200903137)

The subject weekly samples were analyzed for gross beta and results were consistent with historical values. Quarterly composites of the weekly samples were also analyzed by gamma spectroscopy. There was no indication of a plant effect. (Sec. 4.2)

The subject samples are available and the laboratory will perform the analyses pursuant to the ODCM requirements. A supplemental report will be provided upon completion of the analyses.

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

Gamma-spectroscopic analyses were performed with HPGe detectors. Levels of iodine-131 in vegetation and concentrations of airborne iodine-131 in charcoal samples were also determined by gamma spectroscopy.

Tritium was measured by liquid scintillation.

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

Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28, 1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1984.

Environmental, Inc., Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained. Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2003 ). 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.

Attachment to ULNRC-05622 Page 13 of 132 3.5 Program Modifications Milk was no longer available from location M-08 for 2008. Two new milk suppliers, M-09 (Control) and M-10 (Indicator), were added to the program in 2008.

The Pate Farm (V-15) was added to the program in 2008 to include a vegetable location with a higher D/Q value.

On July 8, 2008, the ODCM sampling and analysis requirements were revised as described in FSARCN 08-018. The change to the ODCM will be submitted as required in the Annual Effluent Release Report (AERR). Significant changes were:

Eliminated the gross beta analysis requirement for airborne particulate samples in favor of gamma spectroscopic analysis.

Added samples pursuant to NEI 07-07, "Industry Groundwater Protection Initiative-Final Guidance Document" and ANI Guideline 06-01, "Potential for Unmonitored and Unplanned Off-site Releases of Radioactive Material". Samples added include 24 groundwater well samples, 12 potable well water samples, surface water samples from 9 onsite ponds, shoreline sediment from 4 onsite sludge ponds, 5 soil samples, and 10 samples of food or non-food crops grown on Ameren property traversed by the discharge pipeline.

Added an upstream sample of shoreline sediment (control station).

Revised to allow the use of Optically Stimulated Luminescent Dosimeters (OSLO) for monitoring of direct radiation. The use of Themoluminescent Dosimeters (TLD) continues to be allowed by the ODCM.

Added a requirement, pursuant to ANI Guideline 06-01, to analyze for Hard to Detect (HTD) nuclides if gamma emitting nuclides of plant origin are detected in non-potable well water or surface water samples from onsite ponds, or if nuclides of plant origin are detected in potable groundwater. The HTD nuclides are defined in the ODCM as Sr89, Sr90, Fe55, Ni63, Np237, Pu238, Pu239/240, Pu241, Am241, Cm242 and Cm243/244 .

Table 5.2a summarizes the ODCM sample collection and analysis requirements prior to July 8, 2008, and Table 5.2b summarizes the ODCM sample collection and analysis requirements beginning July 8, 2008.

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 2007, the survey was expanded from a five mile radius to a six 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 census was also expanded to include drinking water wells along Mud Creek and Logan Creek. No new drinking water wells were identified in 2008.

The Land Use Census was completed on October 31, 2008. 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.

Missouri river water intake, within 10 river miles downstream of the plant, is checked, and new construction identified. No new water intake was developed in 2008.

Attachment to ULNRC-05622 Page 15 of 132 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 2008 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 2008.

4.2 Program Findings Results obtained show background levels of radioactivity in the environmental samples collected in 2008.

Airborne Particulates All five air particulate sampling locations are considered indicators. One station is located at the community with the highest D/0, another on the outskirts of Fulton, Missouri.

3 The average annual gross beta concentrations in airborne particulates averaged (0.024 pCi/m )

and ranged from 0.011 to 0.056 pCi/m 3 , similar to levels observed from 1998 through 2007.

Averages are tabulated below.

Year Average (pCi/m 3) Minimum Maximum 1998 0.023 0.006 0.058 1999 0.025 0.008 0.048 2000 0.030 0.012 0.085 2001 0.023 0.006 0.054 2002 0.024 0.010 0.043 2003 0.023 0.009 0.041 2004 0.021 0.010 0.049 2005 0.024 0.005 0.052 2006 0.023 0.010 0.039 2007 0.024 0.011 0.056 2008 0.022 0.009 0.054 Average annual gross beta concentrations in airborne particulates.

Attachment to ULNRC-05622 Page 16 of 132 4.2 Program Findings (continued)

Airborne Particulates During 2008, there were fourteen weekly samples with gross beta activities above the base line 3

action level of 0.037 pCi/m . Gamma spectral analysis was performed on these filters and no gamma emitting isotopes of plant origin were detected.

Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for all locations. Beryllium-?, which is produced continuously in the upper atmosphere by 3

cosmic radiation, was detected, with an average activity of 0.072 pCi/ m . All other gamma-emitting isotopes were below their respective LLD limits.

Airborne Iodine 3

Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m in all samples.

Direct Radiation (TLDsl Forty-three TLDs were placed in 16 sectors around the Callaway site. Measurements from the forty indicator locations averaged 16.5 mrem /quarter. The three control locations averaged 15.6 mrem/quarter. The readings ranged from 11.0 to 20.0 mrem /quarter, with the highest readings from control location CA-l DM-27, with an average of 18.1 mrem /quarter. The differences are statistically insignificant.

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

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 2008 show no radiological effects of plant operation.

Vegetation lodine-131 concentrations in broadleaf vegetation were below the LLD level of 39.6 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.

10

Attachment to ULNRC-05622 Page 17 of 132 4.2 Program Findings (continued)

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 (2,867 and 2,717 pCi/kg wet, respectively).

No plant effect on the fish population is indicated.

Cesium-137 activity was detected at both indicator and control locations, at average concentrations of 523 and 231 pCi/kg dry, respectively. The cesium-137 activity is similar to or less than levels observed from 1998 through 2007, these levels are generally attributable to deposition of fallout from previous decades.

Naturally-occurring potassium-40 averaged 11,784 pCi/kg dry weight.

Analysis results for soil samples in 2008 were consistent with previously accumulated data and no plant operational effects were identified.

Surface Water The automatic sampler at location 801 was operable 100% of the time during 2008 and 94% of the time at location 802. Grab samples were taken as required.

Tritium was the only radionuclide detected in surface water samples collected during 2008. Three of twelve surface water samples collected at indicator location 802, contained measurable levels of tritium with a mean concentration of 398 pCi/L. The results are less than 2.5% of the reporting limit in surface water and well within regulatory requirements. Tritium results for location 802 are being trended along with monthly liquid H-3 releases and Missouri river flow. The 2008 results are consistent with previous operational levels and there was no significant radiological impact on the health and safety of the public or the environment.

Gamma spectroscopic analysis for surface water samples were consistent with previously accumulated data and no plant operational effects were identified.

Ground and Drinking Water (potable water)

Potable ground water from wells D-01 and PW-01 was tested for gross beta, tritium, iodine-131 and gamma-emitting isotopes. The mean gross beta activity measured 5.5 pCi/L, ranging from 4.0 to 8.6 pCi/L and similar to levels observed from 1998 through 2007. lodine-131, tritium and gamma-emitting isotopes all measured below detection levels.

An additional twenty-one wells were added to the program in 2008 and monitored for tritium. No activity was measured above detection level (179 pCi/L) in any of the samples. Ten of the wells were monitored for gamma-emitters. No activities were detected above the respective LLDs.

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

Attachment to ULNRC-05622 Page 18 of 132 Wells and Ponds (non-potable water)

Ground water from wells F-05 and F-15 was tested for gross beta, tritium, iodine-131 and gamma-emitting isotopes. The gross beta activity averaged 9.5 pCi/L, ranging from 8.6 to 10.6 pCi/L.

lodine-131, tritium and gamma-emitting isotopes all measured below detection levels.

Forty-five additional indicator locations, on-site and along the discharge pipeline, were included in the REMP in 2008, and analyzed for tritium. Activity was detected in 36 of the 166 samples tested, at an average activity of 305 pCi/L.The highest concentrations were observed from samples taken at on-site location 936, with an average activity of 551 pCi/L.

Wells OW-1 through OW-5, 936, 937A through 937F 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 absence of tritium in on-site ponds (Pond-1, Pond-2, Outfalls 010 through 015, and sludge lagoon #4) indicate there is no ott-site effect from the washout.

The low level tritium activity observed in wells MW-014 and MW-015 is due to normal operation of air release valves (ARVs) in the discharge pipeline. The pipeline has been replaced and the ARVs have been eliminated. The new discharge pipeline has a single vacuum breaker, which is completely contained to prevent possible leakage to the ground water.

Samples from wells 936, 937A through 937F, MW-004 through MW-008 and MW-012 were also analyzed for gamma-emitting isotopes. No activities were detected above the respective LLDs.

Sediments Bottom sediments were collected in July and November, 2008, and analyzed for gamma-emitting isotopes. Trace Cs-137 activity was detected in one of two control samples at a concentration of 43.0 pCi/kg dry weight. Potassium-40 activity ranged from 11 ,892- 13,913 pCi/kg dry weight and averaged 12,851 pCi/kg dry weight.

Shoreline sediments were also collected in July and November, 2008. A nearly identical distribution of Cs-137 was observed at the control location at a concentration of 41.0 pCi/kg dry weight. Potassium-40 activity ranged from 12,660 - 13,853 pCilkg dry weight and averaged 13,277 pCi/kg dry weight.

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

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

January, 2008 through December, 2008

Attachment to ULNRC-05622 Page 50 of 132 Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.

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

Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

Table A-2 is intentionally left blank.

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.

Attachment to ULNRC-05622 Page 69 of 132 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 = 2a 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 4.66a uncertainty for a background sample.

3.0. Duplicate analyses 3.1 Individual results: For two analysis results; x 1 +/- S1 and X2 +/- s2 Reported result: x +/- s; where x = (1/2) (x 1 + x2 ) and s = (1/2) ~ s12 + si 3.2. Individual results: 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 exampl~, 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 . . . \ are defined as follows:

x 1

r; Lx S

-~

-\j~

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

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

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

4.5 In rounding off, the following rules are followed:

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

4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.

AmerenUE, 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 2008.

Callaway Project 21502, New Technical Training Facility 5.0. Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, operation, tests or experiments installed during 2008, which could involve a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2008, there were two plant designs that 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.

Description of Modification:

This modification covers the construction of a new technical training facility located near the current Callaway Plant training center. This facility will be a one-story building of approximately 32.800 gross square feet with an adjoining parking area. This facility is designed to incorporate offices, classrooms, laboratory and shop areas. It is estimated that approximately 4.6 acres of land will be disturbed during construction of this facility. The new facility will tie-in to existing utilities including plant potable water, sewer, and fire protection systems so there will be no new discharges.

The chemistry training lab will contain two chemical hoods with one exhausting from the building. The chemical sinks will tie into the building drain system and this small quantity of incidental laboratory chemicals will be routed to the existing sanitary sewer. The loading on the existing sewage treatment facility will not change with the construction of this facility as the number of plant staff is not increasing.

The Missouri Department of Natural Resources (DNR) was contacted concerning the tie in for potable water for this facility. DNR indicated that the project could be considered a service connection tie-in and not a main extension. Therefore, a drinking water construction permit application was not required.

Storm water drainage from approximately 3.3 acres of this site will be to Storm Water Outfall #013 (NPDES Permit M0-0098001 ). Approximately 1.3 acres of-the project will drain towards the Plant Operations Access Road to Mud Creek via an unnamed tributary. This required that a Land Disturbance Storm Water Permit be obtained prior to beginning construction, as more than one acre of land will be disturbed. A formal Storm Water Pollution Prevention Plan along with a Best Management Practices Plan was submitted to the Missouri DNR Northwest Regional Office and the land disturbance permit was issued September 14, 2007.

The Cultural Resources Management Plan was reviewed and no significant archeological sites were identified at the proposed location for the new technical training facility.

The new technical training facility was started in December 2007 with an expected completion date in the early 2009.

Evaluation of Change:

As part of this evaluation for construction of the new technical training facility, both the Callaway Plant ER and FES-OL were reviewed for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated. This modification involves construction of a new training building located between the existing plant employee parking area and County Road 459. The project site was previously disturbed during initial plant construction. Utilities including potable water, drinking water, and drains will be connected to existing Callaway systems already permitted by the State of Missouri. Construction of the new technical training facility did not adversely impact the environment as the construction will be confined to areas previously disturbed and storm water runoff will be controlled as agreed upon with the Missouri DNR.

FSARCN 07-047, New Recycle Hold-up Tanks Diaphragm Description of Modification:

Revise the FSAR to add discussion on the new diaphragms installed in the Recycle Holdup Tanks (RHUT) by plant modification MP 06-01 02. This modification package installed a new diaphragm to restore the diaphragm that was part of original plant design removed by MP 95-1013. As a result of the Modification, FSARCN 07-047 will insert the FSAR text that was removed by FSARCNs03-007 and 96-001 associated with plant modification MP 95-1 013. In addition, this change will add the RHUTs to the list of components serviced with nitrogen.

Evaluation of Change:

Since this FSARCN will restore the FSAR text back to the original design, the ER or FES-OL as modified by supplements to the FES-OL or environmental impact appraisals is not impacted by this Change.
