SUMMARY

Plant-related activation, corrosion, or fission products were not detected during 2012 in airborne particulate and radioiodine filters, ground water, broadleaf vegetation, shoreline sediment, crops, aquatic vegetation, terrestrial vegetation, bottom sediment, or soil samples. Activation, corrosion or fission products attributable to plant operation were detected during 2012 in surface water, fish, drinking water, and deer samples.Nuclides detected in Radiological Environmental Monitoring Program (REMP) samples were below applicable Nuclear Regulatory Commission (NRC) reporting levels.Based upon the radiological environmental monitoring program results, it was concluded station operations had no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION The 2012 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2012. 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 Effluent Release Program. The Interlaboratory Comparison Program results, a summary of results in the 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 the sample location identifiers, distances and directions 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.2012 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. Gross beta analysis was performed on the air particulate filters. Air particulate filters were also analyzed quarterly for gamma emitting isotopes.

Charcoal canisters were analyzed for 1-131.Air samples were collected from six locations.

The five indicator locations sampled included 2, 18, 32, 37 and 49. A control location near the intersection of 2 0 th Road and Yearling Road (location

53) was also sampled. 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 43 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. Three 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) and 53 (near the intersection of 2 0 th Road and Yearling Road).C. Waterborne Pathway Water samples were analyzed to determine if 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. Four surface water samples from the Coffey County Lake Spillway (SP) location and four surface water samples from the John Redmond Reservoir (JRR) location were also analyzed for Fe-55. The waterborne pathway sample locations are shown in Figures 3 and 5.Monthly grab samples of surface water were collected from the JRR control location and from the SP indicator location.

The SP indicator location is located near the spillway of Coffey County Lake, formerly known as Wolf Creek Lake.Quarterly grab samples of ground water were collected from seven wells. Six locations (C-10, C-49, F-1, G-2, J-1 and J-2) located hydrologically down gradient from the site were used as indicator sample locations.

Location B-12 located hydrologically up gradient from the site was used as a control location.Drinking water was sampled at the water treatment facilities in the towns of Iola (indicator location IO-DW) and Burlington (control.

location BW-15). The Iola facility is located downstream of the site and the Burlington facility is located upstream of the confluence of the Coffey County Lake discharge and the Neosho River. Composite samples were obtained monthly from automatic samplers at each location.

The samplers collected approximately 27 milliliters of water every two hours.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 32 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 Milk was not collected during the sample year. The Land Use Census did not identify any locations producing milk for human consumption within five miles of the plant.Fish were sampled semiannually from the Coffey County Lake (indicator location) and from the tail waters of JRR (control location).

These sample locations are identified in 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 five gardens. Four indicator (B-I, 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 these 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. One crop sample was 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), Ultimate Heat Sink (UHS), Essential Service Water (ESW) channel, Stringtown Cemetery (SC) and the control location (JRR). Gamma isotopic analyses were performed on the bottom sediment samples. Samples obtained from DC, ESW and UHS were also analyzed for Fe-55. Some of the bottom sediment 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.Shoreline sediment samples were collected from indicator locations EEA and SC. Gamma isotopic analyses were performed on the samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 3.Aquatic vegetation was collected from indicator locations DC ALT, EEA, MUDS and SC.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 3.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 32 Terrestrial vegetation (grass) was sampled from the EEA indicator location.

Gamma isotopic analysis was performed on the grass sample. This sample was collected as part of a cooperative sampling effort with the KDHE. The sample location is identified on Figure 4.Soil was sampled from the EEA indicator location.

Gamma isotopic analysis was performed on the soil sample. This sample was collected as part of a cooperative sampling effort with the KDHE. The sample location is identified on Figure 4.A deer was sampled from indicator location A1.5. Gamma isotopic analysis and tritium analysis was performed.

This sample was collected as part of a cooperative sampling effort with the KDHE. The sample location is identified on Figure 4.II. DISCUSSION OF RESULTS Analysis results for pathways are summarized in Appendix B using the format described in Radiological Assessment Branch Technical Position, Revision 1, November 1979 (NRC Generic Letter 79-065). Results for individual samples are listed in Appendix C.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; the 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 2012 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 2012 weekly gross beta analyses range for indicator locations was 0.009 to 0.064 pCi/m 3.The 2012 weekly gross beta analyses range was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2012 (0.029 pCi/m 3)was 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 2012 (0.029 pCi/m 3) was the same as the annual mean of the control location (0.029 pCi/m 3). The indicator location with the highest gross beta annual mean was location 49 (0.031 pCi/mi ) and was slightly higher than the annual mean of the control location (0.029 pCi/m 3).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 2012, the range for Be-7 detected activity was 0.052 to 0.105 pCi/m 3 for indicator locations and the annual mean for indicator locations was 0.082 pCi/m 3.The control location annual mean for Be-7 detected activity (0.090 pCi/m 3) was slightly higher than the annual mean of the indicator locations (0.082 pCi/m 3).1-131 activity was not detected in the weekly analysis of charcoal filters at any location.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 32 The ODCM required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2012 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 standardized 90-day quarter.The annual mean of indicator locations in 2012 was 19.5 mR per standardized 90-day quarter.The annual mean of the control locations in 2012 was 18.6 mR per standardized 90-day quarter.For pre-operational comparison, in 1981, the annual mean of indicator locations was 18.9 mR per standardized 90-day quarter and the annual mean for the control locations was 17.1 mR per standardized 90-day quarter. It should be noted WCGS changed from thermoluminescence dosimeters (TLD) to optically stimulated luminescence (OSL) dosimeters in 2008.The indicator location with the highest annual mean was 47 (24.8 mR per standardized 90-day quarter).

The close proximity of location 47 to the Radwaste Building is likely the reason direct radiation levels are higher at this location.Based upon Condition Report 00027489, improvements were made in measuring and subtracting transit dose in 2010. As expected, the OSL results have increased since 2010.Chart 3 visibly displays the increase of the OSL results. Chart 3 also displays how closely the indicator and control location OSL dosimeter results are for 2012.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 surface water samples collected from the Coffey County Lake Spillway (SP) indicator location during 2012. The annual mean for detected tritium activity at the SP location was 11,435 pCi/L and the range was 10,037 to 12,545 pCi/L. The detected tritium activity was below the 30,000 pCi/L ODCM reporting level.Chart 5 illustrates the yearly averages of surface water tritium data for the spillway location.Chart 5 indicates the average tritium concentration of the Coffey County Lake spillway location may have reached equilibrium.

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.The ODCM required lower limits of detection were met. Radionuclides were not detected by the gamma isotopic analyses or by Fe-55 analyses.2012 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 2012 in ground water samples.(3) Drinking Water Gross beta activity was detected in drinking water samples collected from the indicator location and in samples collected from the control location.

The annual mean of the indicator location gross beta activity (3.0 pCi/L) was slightly higher when compared to the annual mean of the control location gross beta activity (2.8 pCi/L). The 2012 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.

Tritium activity (222 pCi/L) was detected in the first quarter of 2012 at the indicator location.The detected tritium activity was well below the 20,000 pCi/L ODCM reporting level. Condition Report 00052766 concluded due to low Neosho River flows, coupled with wave overlap discharges from Coffey County Lake, WCGS was a plausible source. Tritium activity was not detected in 2012 at the control location.

In 1984 (pre-operational), tritium activity was not detected in any drinking water samples.ODCM required lower limits of detection were met. Additionally, radionuclides were not detected by the 1-131 or gamma isotopic analyses.(4) Shoreline Sediment Naturally occurring K-40 was detected in shoreline sediment samples collected from the DC (indicator) and JRR (control) locations.

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

ODCM required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2012 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.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 32 (2) Fish Naturally occurring K-40 activity was detected in fish samples obtained from the CCL indicator location and in fish samples obtained from the JRR control location.

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

Fish samples were also analyzed for tritium. Fish samples collected from Coffey County Lake had tritium activity detected (7,728 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 (8,948 pCi/kg), would receive a committed effective dose equivalent of 0.012 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 2012 in broadleaf vegetation samples.(4) Crop Samples Gamma analysis detected naturally occurring K-40 activity to be present in the samples collected from the indicator locations and in the sample collected from the control location.K-40 activity was also detected during pre-operational crop monitoring.

K-40 was the only activity detected in the crop samples. The ODCM required lower limits of detection were met.Plant-related activation, corrosion, or fission products were not detected during 2012 in crop samples and no unusual trends were noted.E. Additional Samples Collected (not required by ODCM)(1) Bottom Sediment Gamma analysis detected naturally occurring K-40 activity to be present in the samples collected from the indicator locations and in the samples collected from the control location.K-40 activity was also detected during pre-operational bottom sediment monitoring.

Cs-137 activity was detected in nine out of the seventeen samples obtained from indicator locations (range 26 to 126 pCi/kg, dry). Cs-137 activity was also detected in both samples obtained from the control location (range 45 to 122pCi/kg, dry).2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 32 Cs-137 activity was detected in pre-operational samples. The Cs-137 activity detected in 2012 indicator bottom sediment samples was 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 38 to 462 pCi/kg.)The detected Cs-1 37 activity in the samples collected from the indicator locations was likely due to fallout since the measured activity is within the decay corrected range of pre-operational Cs-1 37 detected activity and Cs-1 37 activity has also been detected in samples collected at the control location.Chart 7 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 7 trendline indicates Cs-137 activity detected at the JRR control location has also been decreasing.

Chart 7 also displays that in recent years, the detected Cs-1 37 activity for the JRR and DC sample locations overlap.Fe-55 activity was not detected in the fourteen samples obtained from indicator locations.

No other radionuclides were detected in bottom sediment samples.Plant-related activation, corrosion, or fission products were not detected in bottom sediment samples and no unusual trends were noted.(2) Aquatic Vegetation Gamma analyses of aquatic vegetation samples obtained from indicator locations detected naturally occurring gamma emitters Be-7 and K-40. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected.

Plant-related activation, corrosion, or fission products were not detected during 2012 in aquatic vegetation samples and no unusual trends were noted.(3) Shoreline Sediment Naturally occurring K-40 activity was detected in the shoreline sediment samples obtained from the EEA and SC indicator locations.

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

Cs-137 activity (234.3 pCi/kg, dry) was detected in the shoreline sediment sample obtained from the EEA indicator location and in the sample obtained from the SC indicator location (75.8 pCi/kg, dry). Cs-137 activity was also detected in pre-operational shoreline sediment samples. Cs-137 activity detected in shoreline sediment samples collected from the DC location from 1982 to 1984 was in the range of 224 to 437 pCi/kg, dry. The decay corrected range of pre-operational Cs-137 activity detected is approximately 119 to 225 pCi/kg, dry. The detected Cs-137 activity in the shoreline sediment samples was likely due to fallout since the results are nearly within the pre-operational decay corrected range. Additionally, Cs-137 activity is routinely detected in soil and sediment samples collected from the control locations.

No other radionuclides were detected.

Plant-related activation, corrosion, or fission products were not detected and no unusual trends were noted.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 32 (4) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in a terrestrial vegetation indicator location sample collected in 2012. No other radionuclides were detected.

Plant-related activation, corrosion or fission products were not detected during 2012 in terrestrial vegetation samples and no unusual trends were noted.(5) Soil Naturally occurring K-40 activity was detected in the EEA indicator location soil sample. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 activity (155 pCi/kg) was detected in the EEA indicator location soil sample. 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 137 to 1,160 pCi/kg. The detected Cs-137 activity in soil sampled in 2012 is within the decay corrected pre-operational range and is likely due to fallout.Plant-related activation, corrosion, or fission products were not detected during 2012 in this soil sample and no unusual trends were noted.(6) Deer Naturally occurring K-40 activity was detected in the deer sample obtained from the indicator location.The deer sample was also analyzed for tritium. The detected tritium was 916 pCi/kg. The detected tritium activity was attributable to plant operation.

No other radionuclides were detected.

No unusual trends were identified.

Ill. PROGRAM REVISIONS/CHANGES Based upon Condition Report 00051888, the descriptions of the air monitoring stations were revised in AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program), to be clearer.For personnel safety reasons, dosimeter locations

1. 4 and #51 were moved within the same sector.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 9 of 32 IV. PROGRAM DEVIATIONS Drinking Water Samples Drinking water was not continuously collected at the Burlington control sample location during the 08-06-2012 to 09-04-2012 sample period due to an equipment malfunction (ruptured tube).Approximately 2-1/2 gallons of water was collected before the sampler stopped operating.

The composited sample and a grab sample were submitted to the vendor lab for analysis.

The drinking water sampler was repaired on the same day of discovery.

Condition Report 00056913 was generated to document the condition.

Drinking water was not continuously collected at the Iola indicator sample location during 09-28-2012 to 10-01-2012 since the sampler intake tubing was not moved following a water plant line-up change. Sufficient water was collected for the monthly composite sample. The drinking water sampler intake tubing was moved on the same day of discovery to a bay that contained water. Condition Report 00058066 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 During 2012, 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 EFFLUENT 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 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 0,194 mRem for 2012.2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 32 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 (11,435 pCi/L), would receive a committed effective dose equivalent of 0.522 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (7,728 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 0.532 mRem per year.It should be noted Coffey County Lake is not used as 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.

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, 2012 through December, 2012 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 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.Al Attachment A ACCEPTANCE CRITERIA FOR "SPIKED" SAMPLES LABORATORY PRECISION:

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

c MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive".

MAPEP does not provide control limits.Investigation was inconclusive, there was not enough sample for reanalysis.

ERA results (A-7) for the same matrix were acceptable.

e No errors found in calculation or procedure, original analysis result; 0.010 +/- 0.010 Bq/filter.

f Reanalysis results were within limits, but low. ERA results (A-7) for the same matrix were acceptable.

The efficiency factor was recalculated for the second round of MAPEP testing. Original analysis results 55.8 +/- 12.6 Bq/L.g Result of reanalysis; 6.74 +/- 0.15 Bq/sample.

Gamma emitters for the vegetation matrix exhibited a high bias, only Co-57 exceeded acceptance limits. Recounted using a geometry more closely matched to the MAPEP sample size.Result of reanalysis; 0.070 +/- 0.013 Bq/filter.

Result of reanalysis; 0.013 + 0.005 pCi/filter.

A larger sample size was used to reduce the counting error.Result of reanalysis 1.07 t 0.06 pCi/L. The analyses of the MAPEP sample matrix resulted in recovery factors greater than 100%.A correction was made using recovery based on analysis of blank samples. A new tracer solution is on order, future samples for MAPEP testing will include batch spike and blank samples.A6-3 TABLE A-7.

SUMMARY

The 2012 Land Use Census Report has been revised to incorporate information received since the initial report was completed in October 2012.The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2012 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.

The two broadleaf vegetation locations with the highest calculated annual average D/Q rankings are A2.60-17TE1520 and Q2.35-MILA1619.

AP 07B-004 specifies, "Alternate sampling locations may be used to provide continued monitoring".

The third-ranked garden is N2.38-RODR9.

The landowners of these gardens have agreed to participate in the 2013 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 Over two hundred 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 1-3.Calculations were performed so that garden locations could be ranked by their respective D/Q.These results are contained in Table 4.2012 Land Use Census Report, Revision 1 2012 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page D -2 RESULTS NOTE: A Global Positioning System was used to verify residence distances and sectors.One change was noted for the nearest occupied residences in each sector. That change occurred in sector R.Ten changes were noted for the nearest garden producing broadleaf vegetation.
