SUMMARY

Plant-related activation, corrosion, or fission products were not detected during 2013 in airborne particulate and radioiodine, filters, drinking water, 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 2013 in surface water, fish, 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 2013 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2013. 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 and sample locations, sample collection frequency, and type and frequency of analysis.

Table 2 lists the sample location identifiers, distances and directions from the plant. Samples in addition to those required by AP 07B-004 were also obtained and analyzed.The following is a description of the sampling and analysis program by individual pathways.2013 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 air particulate and radioiodine samples on 47 mm glass fiber filters and charcoal canisters, respectively.

The air particulate 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 20th Road and Yearling Road (location

53) was also sampled. Indicator sample locations are shown in Figure 1 and the control sample location is shown in Figure 5.B: Direct Radiation Pathway Optically stimulated luminescence (OSL) dosimeters were used continuously 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 and analyzed for gamma dose.Transit dose was measured and subtracted from the ambient dose. Indicator OSL sample locations are illustrated in Figure 2 and control sample locations are shown in Figure 5. Control sample 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 sample 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 sample location.Drinking water was sampled at the water treatment facilities in the towns of Iola (indicator sample location IO-DW) and Burlington (control sample 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 drinking water automatic samplers collected approximately 27 milliliters of water every two hours.2013 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 sample location) and from the tail waters of JRR (control sample location).

These sample locations are identified in Figure 4. Gamma isotopic analyses were performed on the boneless edible 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. Three indicator (B-1, H-2 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 sample locations (NR-D1 and NR-D2)downstream of the confluence of Wolf Creek and the Neosho River. Crops were also sampled 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 AP 07B-004)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 sample 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, and the control sample 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 sample location EEA. Gamma isotopic analyses were performed on the samples. These samples were collected as part of a cooperative sampling effort with the KDHE. This sample location is identified on Figure 3.Aquatic vegetation was collected from indicator sample locations DC ALT, 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.Terrestrial vegetation (grass) was sampled from the EEA and MUDS indicator sample locations.

Gamma isotopic analyses were performed on the grass samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 32 Soil was sampled from the EEA and MUDS indicator sample locations.

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.A deer was sampled from indicator sample location R2.7. Gamma isotopic analysis and tritium analysis was performed on the deer sample. 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 for all of the airborne sample locations.

Chart 2 represents the gross beta historical airborne smoothed averages of indicator sample locations and control sample locations.

Charts 1 and 2 demonstrate how closely the indicator and control sample 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 2013 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 2013 weekly gross beta analyses range for indicator locations was 0.009 to 0.050 pCi/mi 3.The 2013 weekly gross beta analyses range was lower than the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2013 (0.026 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 2013 (0.026 pCi/m 3) was the same as the annual mean of the control location (0.026 pCi/m 3). The indicator location with the highest gross beta annual mean was location 49 (0.027 pCi/m 3) and was slightly higher than the annual mean of the control location (0.026 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 2013, the range for Be-7 detected activity was 0.052 to 0.092 pCi/m 3 for indicator locations and the annual mean for indicator locations was 0.076 pCi/m 3.The annual mean of the indicator locations (0.076 pCi/m 3)was the same as the annual mean of the control location (0.076 pCi/m 3).1-131 activity was not detected in the weekly analysis of charcoal filters at any location.The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2013 in airborne particulate and radioiodine filters and no unusual trends were noted.2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 32 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 sample locations in 2013 was 18.7 mR per standardized 90-day quarter. The annual mean of the control sample locations in 2013 was 19.5 mR per standardized 90-day quarter.For pre-operational comparison, in 1981, the annual mean of indicator sample locations was 18.9 mR per standardized 90-day quarter and the annual mean for the control sample 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 sample location with the highest annual mean was 47 (24.2 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 2013.Chart 4 displays the TLD nearsite sample locations (1, 2, 7-9, 11-14, 18, 26, 27, 29, 30, 37 and 38) and the control sample 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 sample location.

The annual mean for detected tritium activity at the SP location was 11,100 pCi/L and the range was 9,295 to 13,170 pCi/L.The detected tritium activity was below the'30,000 pCi/L AP 07B-004 reporting level. Chart 5 illustrates the yearly averages of surface water tritium data for the spillway (SP) location.

Chart 5 indicates the average tritium concentration of the Coffey County Lake spillway (SP) location has reached equilibrium.

Tritium activity was not detected in samples obtained from the control sample location (JRR).During pre-operational radiological environmental monitoring, measured radiological activity was not detected in surface water samples.The AP 07B-004 required lower limits of detection were met. Radionuclides were not detected by the gamma isotopic analyses or by Fe-55 analyses.Tritium was the only activity detected during 2013 in surface water samples and no unusual trends were noted.2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 32 (2) Ground Water The AP 07B-004 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 2013 in ground water samples.(3) Drinking Water Gross beta activity was detected in drinking water samples collected from the indicator sample location and in samples collected from the control sample location.

The annual mean of the indicator sample location gross beta activity (2.9 pCi/L) was lower when compared to the annual mean of the control sample location gross beta activity (3.1 pCi/L). The 2013 annual means of gross beta activity for both the indicator and control sample locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the indicator sample location gross beta activity was 7.5 pCi/L and the annual mean of the control sample 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 sample locations.

Radionuclides were not detected by the 1-131 or gamma isotopic analyses.The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2013 in drinking water samples and no unusual trends were noted.(4) Shoreline Sediment Naturally occurring K-40 was detected in shoreline sediment samples collected from the DC (indicator sample location) and JRR (control sample location).

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

No other radionuclides were detected in the DC or JRR shoreline sediment samples during 2013.The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2013 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.2013 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 sample location and in fish samples obtained from the JRR control sample 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 (7,743 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 (8,852 pCi/kg), would receive a committed effective dose equivalent of 0.012 mRem.Tritium activity was not detected in the control location samples collected from JRR.No other radionuclides were detected in fish samples during 2013. The AP 07B-004 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 sample 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 samples during the year.The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2013 in broadleaf vegetation samples no unusual trends were noted.(4) Crop Samples Gamma analysis detected naturally occurring K-40 activity to be present in the samples collected from the indicator sample locations and in the samples collected from the control sample location.

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

K-40 was the only activity detected in the crop samples.The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2013 in crop samples and no unusual trends were noted.E. Additional Samples Collected (not required by AP 07B-004)(1) Bottom Sediment Gamma analysis detected naturally occurring K-40 activity to be present in the samples collected from the indicator sample locations and in the samples collected from the control sample location.

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

2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 32 Cs-137 activity was detected in twelve samples obtained from indicator locations (range 38 to 108 pCi/kg, dry). Cs-137 activity was also detected in one sample obtained from the control sample location (85 pCi/kg, dry).Cs-137 activity was detected in pre-operational samples. The Cs-137 activity detected in 2013 indicator sample location 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 457 pCi/kg.)The detected Cs-137 activity in the samples collected from the indicator sample locations was likely due to fallout since the measured activity is within the decay corrected range of pre-operational Cs-137 detected activity and Cs-137 activity has also been detected in samples collected at the control sample location.Chart 7 plots the Cs-1 37 detected activity from the discharge cove indicator sample location and JRR control sample 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 sample locations.

No other radionuclides were detected in bottom sediment samples.Plant-related activation, corrosion, or fission products were not detected during 2013 in bottom sediment samples and no unusual trends were noted.(2) Aquatic Vegetation Gamma analyses of aquatic vegetation samples obtained from indicator sample 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 in aquatic vegetation samples. Plant-related activation, corrosion, or fission products were not detected during 2013 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 indicator sample location.

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

Cs-137 activity (89.2 pCi/kg, dry) was detected in a shoreline sediment sample obtained from the EEA indicator sample location.

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-1 37 activity detected is approximately 115 to 218 pCi/kg, dry. The detected Cs-137 activity in the shoreline sediment sample was likely due to fallout since the results are lower than the pre-operational decay corrected range. Additionally, Cs-1 37 activity is routinely detected in soil and sediment samples collected from the control locations.

2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 32 No other radionuclides were detected in the EEA shoreline sediment samples. Plant-related activation, corrosion, or fission products were not detected during 2013 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. No other radionuclides were detected in terrestrial vegetation.

Plant-related activation, corrosion or fission products were not detected during 2013 in terrestrial vegetation samples and no unusual trends were noted.(5) Soil Naturally occurring K-40 activity was detected in soil samples obtained from the indicator locations.

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

Cs-137 activity (range 148 to 250 pCi/kg) was detected in soil samples obtained from the indicator locations.

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. The decay corrected range of pre-operational Cs-137 activity detected in soil is approximately 134 to 1,137 pCi/kg. The detected Cs-137 activity in soil sampled in 2013 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 2013 in soil samples and no unusual trends were noted.(6) Deer Naturally occurring K-40 activity was detected in the deer sample obtained from the indicator location.Tritium activity (251 pCi/kg) was also detected in the deer sample. The detected tritium activity was attributable to plant operation.

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

Ill. PROGRAM REVISIONS/CHANGES Based upon the 2012 Land Use Census Report, Revision 1, broadleaf vegetation sample location A-3 was added to AP 07B-004 and broadleaf vegetation sample location N-1 was changed to an alternate sample location.AP 07B-004 was revised to update the description of dosimeter location 44 to Wilson Cadman Wildlife Education Area to match the recent name change.2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 9 of 32 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.Location Sample Period Percent Explanation of DeviationlComments Discrepancy/

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 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.2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 32 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 0.165 mRem for 2013.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 (11,100 pCi/L), would receive a committed effective dose equivalent of 0.507 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (7,743 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 0.517 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.

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

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 through December, 2013 Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories.

The purpose of such a program is to provide an independent check on a 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:

Results are reported in units of pCi/L, except for air filters (pCi/Filter), vegetation and soil (pCi/kg).Unless otherwise indicated, the laboratory result is given as the mean +/- standard deviation for three determinations.

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

Control limits are not provided.A7-2 Appendix B Summary Tables in the format of NRC Radiological Assessment Branch Technical Position Revision 1, November 1979 Page B-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM

SUMMARY

The 2013 Land Use Census Report has been revised to incorporate the re-calculated D/Qs for the broadleaf vegetation locations using the data from Engineering Evaluation SA-1 3-002.The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2013 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 A2.60-17TE1527 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. Since these gardens are currently listed as sample locations for the Radiological Environmental Monitoring Program in procedure AP 07B-004 (locations A-3, Q-6 and N-I), no program changes are necessary regarding broadleaf vegetation locations.

BACKGROUND Section 5.2, Attachment A, of 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." Table 5-1, Attachment A, of procedure 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 procedure 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 and 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 in each sector 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 4.2013 Land Use Census Report, Revision 1 2013 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.Two changes were noted for the nearest occupied residences in each sector. These changes occurred in sectors A and E.Seven 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.

It should be noted that since the last Land Use Census some of the address numbers were changed by the County. Addresses that were affected are identified by an asterisk on Table 2 and Table 3.2013 Land Use Census Report, Revision 1 2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page D -3 TABLE I 2013 Land Use Census Data Location of Nearest: Sector A B C D E F G H J K L M N P Q R Residence A2.47-17RD1474 B3.53-QURD1755 Cl .92-16RD1703 D2.03-QULA1571 E1.77-QULA1485 F1.84-QULA1419 G3.03-13RD1820 H3.09-12RD1711 J3.70-11 RD1540 K2.70-12LA1439 L2.10-NARD 1339 M2.34-14RD1 346 N2.08-15RD1350 P2.76-HW751534 Q2.35-MILA1619 R2.08-NALN 1650 Milkingq Animals None None None None None None None None None None None None None None None None Broadleaf Garden A2.60-17TEl 527 None C3.58-RERD1675 D3.00-16RD1829 None F2.44-RERD1391 G3.77-12RD1831 H3.89-1 1 RD1 655 J3.70-1 1RD1540 K4.10-NARD1120 L2.39-NARD1309 M3.78-LYRD1 390 N2.38-RODR9 P2.93-BRST250 Q2.35-MILA1619 None Identifiers are based upon the following protocol: EXAMPLE: A2.47-17RD1474"A" = Sector A"2.47" = 2.47 miles from the reactor"17RD1474" = address 2013 Land Use Census Report, Revision 1 2013 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page D -4 TABLE 2 SECTOR 2012 NEAREST 2013 NEAREST RESIDENCE RESIDENCE A A2.60-17TE1520 A2.47-17RD1474 B B3.53-QURD1755 B3.53-QURD1755 C Cl.92-16RD1655 Cl.92-16RD1703*
