EXECUTIVE

SUMMARY

Plant-related activation, corrosion or fission products were not detected during 2009 in airborne particulate and radioiodine filters, ground water, drinking water, broadleaf vegetation, shoreline sediment, crops, terrestrial vegetation, aquatic vegetation, or soil samples.

Activation, corrosion or fission products attributable to plant operation were detected during 2009 in surface water, fish, deer, and bottom sediment samples.

Nuclides detected in Radiological Environmental Monitoring Program (REMP) samples were below applicable NRC reporting levels.

Based upon the radiological environmental monitoring program results, it was concluded that station operations had no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION The 2009 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2009. WCGS is located in Coffey County, Kansas, approximately five miles northeast of Burlington, Kansas.

Fuel loading commenced at WCGS on March 12, 1985. The operational phase of the REMP began with initial criticality on May 22, 1985, and the first detectable quantities of radioactivity were reported in plant effluents in June 1985.

This report contains a description of the REMP conducted by Wolf Creek Nuclear Operating Corporation (WCNOC), a discussion of monitoring program results, the revisions or changes to the program, program deviations, the Interlaboratory Comparison Program and a comparison to the Radioactive Effluents Release Program. The Interlaboratory Comparison Program results, a summary of results in the Nuclear Regulatory Commission (NRC) Branch Technical Position specified format, the individual sample results and the Land Use Census Report are included as appendices.

I. PROGRAM DESCRIPTION Radiological environmental monitoring samples were collected according to the schedule in WCGS procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program). Radiological environmental monitoring program samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc.

Landauer, Inc.

processed the environmental optically stimulated luminescence (OSL) dosimeters. Table 1 identifies the exposure pathway/sample type, number of samples/sample locations, sample collection frequency and type/frequency of analysis.

Table 2 lists each sample location's distance and direction from the plant. Samples in addition to those required by the WCGS Offsite Dose Calculation Manual (ODCM) were also obtained and analyzed.

The following is a description of the sampling and analysis program by individual pathways.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 32

A. Airborne Pathway Low volume air sampling pumps with digital flow meters continuously collected particulate and radioiodine samples on 47 mm glass fiber filters and charcoal canisters, respectively.

The filters and charcoal canisters were changed out weekly, labeled, and shipped to Environmental, Inc. for analyses.

Gross beta analyses of the air particulate filters were performed after a nominal 72-hour period to allow the radon and thoron daughter products to decay.

Weekly air particulate filters were combined into quarterly composites for each location and analyzed for gamma emitting isotopes.

Charcoal canisters were routinely counted to determine the presence or absence of 1-131.

Positive indication of 1-131 would have resulted in analysis of each individual charcoal canister.

Air samples were collected from six locations. Indicator locations 2, 37 and 49 are located in the three sectors with the highest ground level deposition constants (D/Q).

Air sampling stations are also located in the community of New Strawn (indicator location 32) and a control location near the intersection of 2 0 th Road and Yearling Road (location 53).

Supplemental indicator location (location 18) was also sampled during the year. Indicator locations are shown in Figure 1 and the control location is shown in Figure 5.

B. Direct Radiation Pathway Optically stimulated luminescence (OSL) dosimeters were used at 44 locations during the sample year to measure direct radiation. The OSLs were typically positioned roughly 3 to 4 feet above the ground in plastic thermostat boxes. Two OSLs were placed at each designated location. The OSLs were changed out quarterly. Transit dose was measured and subtracted from the ambient dose. Indicator OSL sample locations are illustrated in Figure 2 and control locations are shown in Figure 5. Control locations were 39 (Beto Junction), 48 (Harris) and 53 (near the intersection of 2 0 th Road and Yearling Road).

C. Waterborne Pathway All water samples were analyzed to determine whether gamma emitters were present.

In addition to gamma isotopic analysis, radiochemical analysis for 1-131 was performed on drinking water and ground water samples. Gross beta analysis was also performed on drinking water samples. Tritium analysis was performed monthly by liquid scintillation for surface water and quarterly for drinking water.

Tritium analysis was also performed on ground water samples. Water sampling locations are shown in Figures 3 and 5.

Monthly grab samples of surface water were collected from John Redmond Reservoir (JRR) as a control location and from the "SP" location, which is located near the spillway of Coffey County Lake, formerly known as Wolf Creek Lake, as an indicator location.

Quarterly grab samples of ground water were collected from seven wells.

Location B-12 is hydrologically up gradient from the site and was used as a control location. Six locations (C-10, C-49, F-1, G-2, J-1 and J-2) are hydrologically down gradient from the site and were used as indicator sample locations.

Drinking water was sampled at the water treatment facilities for the towns of Burlington (control location BW-15) and Iola (indicator location IO-DW). The Burlington facility is located upstream and the Iola facility is located downstream of the confluence of the discharge from Coffey County Lake and the Neosho River.

Composite samples were obtained monthly from automatic samplers at each location that-collected approximately 27 ml of drinking water every two hours.

Shoreline sediments were sampled semiannually. Gamma isotopic analyses were performed on the shoreline sediment samples.

Shoreline sediment sample locations were the Coffey County Lake discharge cove (DC) indicator location and the JRR control location.

D. Ingestion Pathway Because no sampling locations that produce milk for human consumption were identified within five miles of the plant, milk was not collected during the sample year.

Fish were sampled semiannually from the tail waters of JRR (control, Figure 4) and from Coffey County Lake (indicator, Figure 4). Gamma isotopic analyses were performed on the boneless meat portions of the fish. Several species of game fish and rough fish were sampled. Fish were also analyzed for tritium.

Broadleaf vegetation samples were collected monthly when available during the growing season from four gardens. Three indicator (H-2, N-1 and Q-6) gardens (Figure 4) and one control (D-2) garden (Figure 5) were sampled. Gamma isotopic analyses were performed on all samples.

Crop samples were obtained from two indicator locations (NR-D1 and NR-D2) downstream of the confluence of Wolf Creek and the Neosho River. Two crop samples were obtained from control location NR-U1.

Gamma isotopic analysis was performed on each sample.

Crop sample locations are identified on Figure 5.

E. Additional Samples Collected (not required by ODCM)

Quarterly, duplicate ground water grab samples were obtained from indicator location C-49 and were labeled L-49. These duplicate samples served as laboratory quality checks. The ground water samples were analyzed for gamma emitters, 1-131 and tritium.

Bottom sediment samples were collected from indicator locations at the Coffey County Lake discharge cove (DC), Environmental Education Area (EEA), Make-Up Discharge Structure (MUDS) and the control location (JRR).

Gamma isotopic analyses were performed on the bottom sediment samples. These indicator samples were collected as part of a cooperative sampling effort with the Kansas Department of Health and Environment (KDHE). The sample locations are identified on Figure 3.

Aquatic vegetation was collected from indicator locations EEA and MUDS.

Gamma isotopic analyses were performed on the aquatic vegetation samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 3.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 32

Terrestrial vegetation was sampled from indicator locations EEA and MUDS. Gamma isotopic analyses were performed on the terrestrial vegetation samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.

Soil was sampled from indicator locations MUDS and EEA. Gamma isotopic analyses were performed on the soil samples.

These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.

Two road-killed deer were sampled from indicator locations BI.0 and R2.5. Gamma isotopic analyses and tritium analyses were performed.

These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.

II. DISCUSSION OF RESULTS Analysis results for all pathways are summarized in Appendix B using the format described in Radiological Assessment Branch Technical Position, Revisions.1, November 1979 (NRC Generic Letter 79-065). Results for individual samples are listed in Appendix C.

In this section, results are discussed by pathway and analysis type.

Monitoring results are compared with control data, preoperational values, sources of radioactivity, and effluent releases when applicable. Trends or seasonal effects are discussed.

A. Airborne Pathway Chart 1 graphically illustrates weekly gross beta results for the sample year. Chart 2 represents the historical smoothed averages of indicator locations and the control locations gross beta data.

Charts 1 and 2 demonstrate how closely the indicator and control locations tracked together.

Chart 2 reveals a seasonal cyclic trend in which gross beta values peak in the winter months (December or January) and decrease to a low point in the spring months (May or June). This trend is expected and is attributed to seasonal meteorological changes, i.e., changes in prevailing winds and precipitation.

The gross beta results of 2009 were compared to pre-operational monitoring results of 1983 and 1984.

The weekly gross beta analyses range for 1983 and 1984 was 0.0064 to 0.084 pCi/m 3. The 2009 weekly gross beta analyses range for indicator locations was 0.011 to 0.053 pCi/m 3, which was lower than the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2009 (0.031 pCi/m 3) was slightly lower than the annual mean for 1983 (0.032 pCi/m 3).

The gross beta results for the indicator locations were also compared to the control location.

The annual mean for indicator locations for 2009 (0.031 pCi/m 3) was the same as the annual mean of the control location (0.031 pCi/m 3). The indicator location with the highest gross beta annual mean was location 32 (0.032 pCi/mi), which was slightly higher than the annual mean of the control location (0.031 pCi/m 3).

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 32

Naturally occurring Be-7 activity was detected, as was the case during pre-operational monitoring.

In 1984, the range for Be-7 detected activity was 0.024 to 0.211 pCi/m 3 for indicator locations and the annual mean for indicator locations was 0.069 pCi/m 3. In 2009, the range for Be-7 detected activity was 0.060 to 0.122 pCi/m 3 for indicator locations and the annual mean for indicator locations was 0.093 pCi/m 3.

The control location annual mean for Be-7 detected activity (0.097 pCi/m 3) was slightly higher than the indicator locations annual mean (0.093 pCi/m 3).

1-131 activity was not detected in the weekly analysis of charcoal filters at any location.

Plant-related activation, corrosion or fission products were not detected during 2009 in airborne particulate and radioiodine filters and no unusual trends were noted.

B. Direct Radiation Pathway Quarterly OSL dosimeter results for each location are shown in Table 3. Measured values have been converted to a standard 90-day quarter.

The annual mean of all indicator locations in 2009 was 0.132 mR/day and the annual mean for the control locations was also 0.132 mR/day.

For pre-operational comparison, in 1981, the annual mean of all indicator locations was 0.21 mR/day and annual mean for the control locations was 0.19 mR/day.

The indicator location with the highest annual mean was 47 (0.194 mR/day).

The close proximity of location 47 to the Radwaste Building is likely the reason direct radiation levels are higher at this location.

Chart 3 displays how closely the indicator and control location OSL dosimeter results are for 2009.

Chart 4 displays the TLD nearsite locations (1, 2, 7-9, 11-14, 18, 26, 27, 29, 30, 37 and 38) and the control locations (locations 39 and 48) for the preoperational years through 2007.

C. Waterborne Pathway (1) Surface Water Tritium, attributable to WCGS operation, was detected in all surface water samples collected from Coffey County Lake during 2009. Chart 5 illustrates the yearly averages of surface water tritium data for the spillway location. Chart 5 indicates that the average tritium concentration of the Coffey County Lake may have reached equilibrium.

ODCM required lower limits of detection were met and tritium activity was not detected in samples obtained from the control location (JRR).

During pre-operational radiological environmental monitoring, measured radiological activity was not detected in surface water samples.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 32

Tritium was the only activity detected in surface water samples and no unusual trends were noted.

(2) Ground Water ODCM required lower limits of detection were met for 1-131, tritium and gamma isotopic analyses. Radioactivity was not detected in any ground water samples. No unusual trends were noted. Plant-related activation, corrosion or fission products were not detected during 2009 in ground water samples.

(3) Drinking Water Gross beta activity was detected in all drinking water samples collected from the indicator location and the control location. The annual mean of the indicator location gross beta activity (3.1 pCi/L) was similar when compared to the annual mean of the control location gross beta activity (2.9 pCi/L). The 2009 annual means of gross beta activity for both the indicator and control locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the indicator location gross beta activity was 7.5 pCi/L and the annual mean of the control location gross beta activity was 6.4 pCi/L.

Chart 6 illustrates the drinking water gross beta results for the last five years and how closely the gross beta results compared for the indicator and control locations.

ODCM required lower limits of detection were met.

Additionally, radionuclides were not detected by the 1-131, Tritium or gamma isotopic analyses.

Plant-related activation, corrosion or fission products were not detected during 2009 in drinking water samples and no unusual trends were noted.

(4) Shoreline Sediment Naturally occurring K-40 was detected in all shoreline sediment samples.

K-40 was also detected during pre-operational shoreline sediment monitoring.

Cs-1 37 activity was detected in both shoreline sediment samples obtained from the JRR control location. The detected Cs-137 activity at the control location was likely due to fallout. Cs-137 activity was not detected in the shoreline sediment samples obtained from the DC indicator location.

ODCM required lower limits of detection were met. Plant-related activation, corrosion or fission products were not detected during 2009 in shoreline sediment samples and no unusual trends were noted.

D. Ingestion Pathway (1) Milk Milk was not collected during the sample year since no indicator locations within five miles of the plant were identified during the Land Use Census.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 32

(2) Fish Naturally occurring K-40 activity was detected in all fish samples obtained from the CCL indicator location and the JRR control location.

K-40 activity was also detected during pre-operational fish monitoring.

During 2009, fish were also analyzed for tritium.

All fish samples taken from Coffey County Lake had tritium activity detected (7,764 pCi/kg annual mean). The detected tritium activity was attributable to plant operation.

An adult consuming 21 kilograms of fish, at the maximum measured tritium concentration for 2009 (9,550 pCi/kg), would receive a committed effective dose equivalent of 0.013 mRem.

Tritium activity was not detected in the control samples collected from JRR.

No other radionuclides were detected in fish during the year. The ODCM required lower limits of detection were met and no unusual trends were noted.

(3) Broadleaf Vegetation Gamma analyses of broadleaf vegetation samples obtained from indicator and control locations detected naturally occurring gamma emitters Be-7 and K-40. Be-7 and K-40 activity were also detected pre-operationally.

No other radionuclides were detected in broadleaf vegetation during the year. The ODCM required lower limits of detection were met and no unusual trends were noted. Plant-related activation, corrosion or fission products were not detected during 2009 in broadleaf vegetation samples.

(4) Crop Samples Gamma analysis detected naturally occurring K-40 activity to be present in all of the samples.

K-40 activity was also detected during pre-operational crop monitoring.

K-40 was the only activity detected in crop samples. Plant-related activation, corrosion or fission products were not detected during 2009 in crop samples and no unusual trends were noted.

E. Additional Samples Collected (not required by ODCM)

(1) Bottom Sediment Naturally occurring K-40 was detected in all of the bottom sediment samples obtained from the indicator locations and the control locations.

K-40 activity was also detected during pre-operational bottom sediment monitoring.

Co-60 activity (57.9 pCi/kg) was detected in an indicator sample obtained from the Coffey County Lake discharge cove. Co-60 activity was attributable to plant operation and has been identified in plant effluents.

Co-60 activity was not detected in pre-operational radiological environmental monitoring and was not detected in samples collected from control location JRR during 2009. Chart 7 plots the Co-60 detected activity from the discharge cove and reflects a decreasing trend. This downward trend is due to improvements made in the process system.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 32

Cs-137 activity (125.5 and 169.4 pCi/kg) was detected in both of the indicator location samples obtained from the Coffey County Lake discharge cove. A portion of this activity is due to fallout and a portion of this activity is likely plant-related since Cs-134 activity has been detected in the past.

Cs-137 activity was detected in pre-operational samples, and the results for 2009 indicator bottom sediment samples were within the pre-operational range.

(Cs-137 activity detected in 1981 and 1982 was in the range of 79 to 953 pCi/kg. The decay corrected range of pre-operational Cs-1 37 activity detected is approximately 41 to 490 pCi/kg.) Cs-137 activity has been identified in plant effluents.

Cs-137 activity (138.0 pCi/kg) was also detected in one control location (JRR) bottom sediment sample.

Cs-137 activity (51.3, 76.5 and 82.4 pCi/kg) was also detected in three indicator location samples obtained from the Environmental Education Area (EEA). Since the detected Cs-137 activity was lower than the detected Cs-137 activity measured at the JRR control location (138.0 pCi/kg), this activity was likely due to fallout and not attributed to plant operation.

Chart 8 plots the Cs-137 detected activity from the discharge cove indicator location and JRR control location bottom sediment samples. The detected Cs-137 activity measured from the discharge cove location reflects a decreasing trend. The Chart 8 trend line indicates that as expected, Cs-1 37 activity detected at the JRR control location has been decreasing.

No other radionuclides were detected in bottom sediment samples and no unusual trends were noted.

(3) Aquatic Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2009. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected in aquatic vegetation samples. Plant-related activation, corrosion or fission products were not detected during 2009 in aquatic vegetation samples and no unusual trends were noted.

(4) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in terrestrial vegetation indicator location samples collected in 2009.

No other radionuclides were detected.

Plant-related activation, corrosion or fission products were not detected during 2009 in terrestrial vegetation samples and no unusual trends were noted.

(5) Soil Naturally occurring K-40 activity was detected in all of the indicator location soil samples. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 activity (285.2 and 405.1 pCi/kg) was also detected in two of the indicator location soil samples (EEA and MUDS).

This activity is likely due to fallout. Data was reviewed for soil samples collected pre-operationally. The detected Cs-137 activity range from February of 1985 was 255 to 2,160 pCi/kg, dry. The decay corrected range of pre-operational Cs-137 activity detected in soil is approximately 143 to 1,212 pCi/kg. The range of the 2009 detected Cs-137 activity in soil is within the decay corrected pre-operational range.

2009 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 32

Plant-related activation, corrosion or fission products were not detected during 2009 in soil samples and no unusual trends were noted.

(6) Deer Naturally occurring K-40 activity was detected in the deer samples obtained from the two indicator locations.

The deer samples were also analyzed for tritium. The detected tritium activity (218 and 496 pCi/kg, wet) was attributable to plant operation.

One deer sample had Cs-1 37 activity (25.1 pCi/kg, wet) detected. This activity was likely due to fallout and not attributed to plant operation since Cs-137 activity was not detected in the broadleaf vegetation samples, the terrestrial vegetation samples, or the air particulate samples.

No other radionuclides were detected in the deer samples. No unusual trends were identified.

Ill. PROGRAM REVISIONS/CHANGES Broadleaf vegetation alternate indicator location C-2 was removed from the REMP since the garden is no longer available to sample.

Alternate company-owned garden locations B-1, H-2, and R-2 were added to the REMP to enhance broadleaf vegetation sampling.

IV. PROGRAM DEVIATIONS Air Samples The following air sample locations failed to meet the requirement for "continuous sampler operation." As described in footnote (1) of procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program), Table 5-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons. Discrepancies greater than five percent between Total Military Time and Total Digital Flow Meter Time, which resulted in a loss of air sample collected, are listed in the following table.

Additionally, on 07-07-2009, the ground fault circuit interrupter protected outlets were replaced.

Drinking Water Samples Drinking water was not continuously collected at Iola during the 08-05-2009 to 09-09-2009 sample period due to a faulty power converter. The power converter was replaced and the sampler was returned to service the same day. Condition Report 00019804 was generated to document the condition.

Drinking water was not continuously collected at Iola during the 12-01-2009 to 01-04-2010 sample period due to a tube becoming disconnected during the sample period. Approximately 3/ of a gallon of water was collected before the tube became disconnected. This sample and a grab sample were submitted to the vendor lab for analysis. Condition Report 00022695 was generated to document the condition.

Irrigated Crop Samples The 1-131 lower limit of detection (LLD) was not met on two irrigated crop samples collected from NR-D2.

A shipping delay was the cause for the missed LLDs.

Condition Report 00022550 was generated to document the condition.

Ground Water Protection The following information is being provided in association with the Nuclear Energy Institute (NEI) Groundwater Protection Industry Initiative:

Describe offsite ground water or surface water sample results that exceeded the REMP reporting criteria that were voluntarily communicated to State/Local officials during the calendar year-None.

V. INTERLABORATORY COMPARISON PROGRAM RESULTS During 2009, Environmental, Inc., Midwest Laboratory was contracted to perform radiological analysis of environmental samples for WCNOC. The lab participated in the intercomparison studies administered by Environmental Resources Associates.

Appendix A is the Interlaboratory Comparison Program Results for Environmental, Inc., Midwest Laboratory.

Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also contained in Appendix A.

VI. COMPARISON TO THE RADIOACTIVE EFFLUENTS RELEASE PROGRAM As described in the section discussing radioisotopes found in fish from Coffey County Lake, dose that may be received as a result of tritium released from WCGS is comparable with the theoretical doses calculated by the Radioactive Effluent Release Program.

The theoretical doses calculated by the Radioactive Effluent Release Program assume that a person drinks the water from Coffey County Lake and eats the fish from Coffey County Lake.

Based upon these assumptions the dose to man from both pathways was calculated to be 0.170 mRem for 2009.

Using sample data obtained from the REMP, an adult drinking 2 liters per day of surface water from Coffey County Lake, using the average tritium activity (11,356 pCi/L), would receive a committed effective dose equivalent of 0.518 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (7,764 pCi/kg), would receive a committed effective dose equivalent of 0.010 mRem per year. Based upon the REMP results, the dose from both pathways was calculated to be 0.528 mRem per year.

It should be noted that the Coffey County Lake is not a drinking water source. Calculating the dose to man for tritium detected in the Coffey County Lake surface water is for comparison purposes only.

The tritium dose values are being compared on a qualitative basis. It is not expected that the annual doses, as calculated in the Radioactive Effluent Release Report, would compare directly to those calculated from the REMP. The Radioactive Effluent Release Report provides a 'snap shot' of potential dose resulting from the year's releases.

The REMP data indicates the accumulated result of releasing tritium into the lake since the start of plant operation.

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, 2009 through December, 2009

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

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

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

Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.

Table A-5 lists REMP specific analytical results from the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors.

Complete analytical data for duplicate analyses is available upon request.

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

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

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

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

c Laboratory codes as follows: STW (water), STAP (air filter), STSO (soil), STVE (vegetation).

MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP.

e Included in the testing series as a "false positive".

f No errors were found in procedure or calculation. There was not enough sample for a reanalysis. Americium-241 in water was included in the ERA studies (Tbl. A-7) and also in the second round of MAPEP testing. Both analysis results were acceptable.

9 One determination was eliminated from the average, due to poor recovery. Average of three determinations, 0.25 +/- 0.03 pCi/filter.

h No reason was determined for the initial high results. The analysis was repeated; result of reanalysis; 0.54 +/- 0.12 Bq/filter.

Incomplete separation of strontium from calcium could result in a higher recovery percentage and consequently lower reported activity. The analysis was repeated; result of reanalysis 363.3 +/- 28.6 Bq/kg.

EXECUTIVE

SUMMARY

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed for 2009 in accordance with AP 07B-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].

No program changes are necessary regarding milk locations. Again, no milk sampling locations were identified.

No program changes are necessary regarding the broadleaf vegetation sample locations. The broadleaf vegetation locations that had the highest calculated annual average D/Q rankings are Q2.35-MILA1619, L2.39-NARD1309 and N2.38-RODR9, respectively. Samples are currently being obtained from locations Q2.35-MILA1619 and N2.38-RODR9.

The garden at L2.39-NARD1 309 will not be added to the sample program for the following reasons:

The difference between the calculated D/Qs for locations L2.39-NARD1309 and N2.38-RODR9 is less than twenty percent.

" The landowner at location L2.39-NARD1309 has not responded to previous requests to add the garden to the REMP sample program.

BACKGROUND Section 5.2, Attachment A, of the ODCM procedure (AP 07B-004), directs that "a Land Use Census shall be conducted annually during the growing season to identify the nearest (1) milk animal, (2) residence, and (3) garden of greater than 500 square feet producing broadleaf vegetation in each of the 16. meteorological sections within five miles of the WCGS site" and "the results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report."

Table 5-1, Attachment A, of the ODCM (AP 07B-004) requires that broadleaf vegetation samples be collected from "two indicator locations (using the criteria from the "Land Use Census" section) with highest calculated annual average D/Q."

Table 5-1, Attachment A, of the ODCM (AP 07B-004) also requires that milk samples be collected from "three indicator locations within 5 miles of the site having the highest dose potential."

METHODOLOGY Two hundred fifteen surveys were mailed to the rural residents living within five miles of WCGS.

A follow-up survey was sent to residents who did not respond.

The survey excluded the residents of New Strawn, Burlington, and a trailer park north of Burlington. These locations were excluded due to the large number of households and the low likelihood that information gained from these residences would affect the locations chosen for REMP sampling. Drive-by information was collected for the nearest residences that did not return surveys.

The information collected was compiled and the results are identified in Tables 1-1 Calculations were performed so that garden locations could be ranked by their respective D/Q.

These results are contained in Table 4.

RESULTS NOTE: A Global Positioning System was used to verify residence distances and sectors.

Four changes were noted for the nearest occupied residences in each sector. Those changes were in sectors B, E, F and M.

Nine location changes were noted for the nearest garden producing broadleaf vegetation.

These changes are identified in Table 3.

There were no changes regarding milk sample locations. Again, no locations were identified that routinely milked animals for human consumption.
