EXECUTIVE

SUMMARY

Plant-related activation, corrosion or fission products were not detected during 2005 in airborne particulate and radioiodine filters, ground water, drinking water, shoreline sediment, broadleaf vegetation, crops, terrestrial vegetation, aquatic vegetation, or soil samples.

Activation, corrosion or fission products attributable to plant operation were detected during 2005 in surface water, fish, and bottom sediment samples.

Nuclides detected in REMP samples were below applicable NRC reporting levels, and program lower limits of detection were met.

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

INTRODUCTION The 2005 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2005. 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 Radiological Environmental Monitoring Program -(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), results of sample analyses, a discussion of monitoring program results, a description of revisions to and deviations from the program, and the results of Interlaboratory Comparison Programs.

Individual sample results and a summary of results in the Nuclear Regulatory Commission (NRC) Branch Technical Position specified format are included as appendices.

1. PROGRAM DESCRIPTION Radiological environmental samples were collected according to the schedule in WCGS procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program).

Environmental samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc.

Detroit Edison processed environmental thermoluminescent dosimeters (TLDs) at the Enrico Fermi 2 plant. Table 1 lists sampling pathways and frequencies of sampling and 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.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 30

A. Airborne Pathway Low volume air sampling pumps 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 analysis. The volume of air sampled was calculated from the average of initial and final flow rates and the total time of collection. Each pump was equipped with a time totalizer that was checked weekly against the elapsed time to identify electrical power outages.

Gross beta analysis of the air particulate samples was 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 in groups of five 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 at Harris (location 48). Supplemental indicator location (location 18) was also sampled during the year. Distances and directions to sampling locations from the plant are listed in Table 2, indicator locations are shown in Figure 1, and the control location is shown in Figure 5.

B. Direct Radiation Pathway Panasonic UD-814-AQ TLDs were used at 47 locations during the sample year. The TLDs consist of one lithium-borate element and three calcium sulfate elements in a plastic case.

TLDs were typically positioned roughly 3 to 4 feet above the ground in plastic thermostat boxes.

The thermostat boxes protect the TLDs from the elements and tampering. Two TLDs were placed at each designated location. The TLDs were changed out quarterly.

Indicator TLD sample locations are illustrated in Figure 2 and control locations are shown in Figure 5. Table 2 provides the distance and direction of each location from the plant. Control locations were 39 (Beto Junction) and 48 (Harris).

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 listed in Table 2 and 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, formally known as Wolf Creek Lake, as an indicator location.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 30

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

Location B-12 is hydrologically up gradient from the site and was used as a control location. Three locations (C-10, C-49, and J-1) 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 Neosho Falls (indicator location NF-DW). The Burlington facility is located upstream and the Neosho Falls 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 analysis was performed on the shoreline sediment samples. Shoreline sediment sample locations were the Coffey County Lake discharge cove (DC) indicator location and at the control location (JRR).

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 analysis was 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. Three indicator (G-1, N-1 and Q-6) gardens (Figure 4) and two control (D-1 and D-2) gardens (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. One crop sample was obtained from control location NR-Ul.

Gamma isotopic analysis was performed on each sample.

Crop sample locations are identified on Figure 5.

E. Additional Samples Collected (not required by ODCM)

Drinking water indicator location 1O-DW (lola) was sampled during the year. The drinking water sample was analyzed for gross beta, gamma emitters, 1-131 and tritium. This sample location was added due to the anticipated closure of the Neosho Falls drinking water treatment facility and is identified on Figure 5.

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. Three indicator ground water sample locations were also sampled during the fourth quarter of 2005 (F-1, G-2 and J-2). The ground water samples were analyzed for gamma emitters, 1-131 and tritium.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 30

Bottom sediment samples were collected at the Environmental Education Area (EEA) and from the Make-Up Discharge Structure (MUDS). Gamma isotopic analysis was 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.

Bottom sediment samples were collected semiannually at the Coffey County Lake discharge cove (DC) indicator location and the control location (JRR).

Gamma isotopic analysis was performed on the bottom sediment 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 EEA and MUDS. Gamma isotopic analysis was 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 was sampled from indicator location EEA. Gamma isotopic analysis was performed on the terrestrial vegetation 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 indicator locations MUDS and EEA.

Gamma isotopic analysis was 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.

Distance and direction information for the sampling locations listed in this section are outlined in Table 2.

II. DISCUSSION OF RESULTS Analysis results for all 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.

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 and control 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.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 30

The gross beta results of 2005 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/M3. The 2005 weekly gross beta analyses range for indicator locations was 0.014 to 0.055 pCi/M3, which was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2005 (0.030 pCi/M3) was lower than the annual mean for 1983 (0.032 pCi/rn3).

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

The annual mean for indicator locations for 2005 (0.030 pCi/M3) was similar to the annual mean of the control location (0.029 pCi/M3).

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/M3 for indicator locations, and the annual mean for indicator locations was 0.069 pCi/M3. In 2005, the range for Be-7 detected activity was 0.057 to 0.107 pCi/im3 for indicator locations, and the annual mean for indicator locations was 0.080 pCi/M3.

The control location annual mean for Be-7 detected activity (0.076 pCi/M3) was similar to the indicator locations annual mean (0.080 pCi/r 3).

Required lower limits of detection were met and 1-131 activity was not detected in the weekly analysis of charcoal filters at any location.

No effects of plant operation were seen via the airborne pathway for the year, and no unusual trends were noted.

B. Direct Radiation Pathway Quarterly gamma exposures measured at 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 2005 was 0.271 mR/day and the annual mean for the control locations was 0.265 mR/day. The exposure measurements for the control locations and the indicator locations were elevated due to the unusually long period of time between the ship dates of the TLDs from the vendor lab and the read times by the vendor lab. This condition has been documented in the corrective action process (PIR 2006-0831).

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.

Results from TLDs located near the plant (less than three miles), which would be most affected by changes in plant operation, were combined into quarterly averages.

These nearsite averages, using locations 1, 2, 7-14, 18, 26-30, 37 and 38, are compared to control location results (locations 39 and 48) in Chart 3.

Chart 3 also includes preoperational data for comparison.

The nearsite TLD locations have historically trended higher than the control locations both prior to and after WCGS became operational. Chart 3 also displays the elevated results for the control locations and the indicator locations.

C. Waterborne Pathway (1) Surface Water Tritium, attributable to WCGS operation, was detected in all surface water samples collected from Coffey County Lake during 2005. Chart 4 illustrates the yearly averages of surface water tritium data for the spillway location.

It can be seen in Chart 4 that surface water tritium concentrations have trended upward since plant startup. This is expected until the average tritium concentration of the lake reaches equilibrium.

Tritium activity (219 +/- 95 pCi/L), not attributable to WCGS operation, was also detected in one surface water sample obtained from the control location (JRR) on October 20. Statistically, the tritium level observed is at the lower end of the vendor laboratory's counting system capability.

Required lower limits of detection were met.

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

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

(2) Ground Water Low levels of tritium, not attributable to WCGS operation, were the only activity detected in ground water samples. Two indicator locations C-10 and C-49 collected on August 11 had tritium detected at levels of 204 +/- 94 pCi/L and 217 +/- 95 pCi/L, respectively. These analysis results were verified by a laboratory re-analysis. Statistically, the tritium levels observed were at the lower end of the vendor laboratory's counting system capability. Additionally, a split sample had been obtained from location C-49 and was labeled L-49. The tritium result for the sample collected on August 11 and labeled location L-49 was <173 pCi/L.

Required lower limits of detection were met.

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

Low levels of tritium were the only activity detected in ground water samples and no unusual trends were noted.

(3) Drinking Water Chart 5 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.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 30

Gross beta activity was detected in all drinking water samples. The annual mean of the control location gross beta activity (3.9 pCIL) was higher when compared to the annual mean of the indicator locations (3.6 pCi/L).

The 2005 annual means of gross beta activity for both the control and indicator locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the control location gross beta activity was 6.4 pCi/L, and the annual mean of the indicator location gross beta activity was 7.5 pCi/L.

During the third quarter of 2005, low levels of tritium activity were detected in the two indicator location samples (lola: 207 +/- 83 pCiL; Neosho Falls: 243 +/- 85 pCi/L) as well as the control location sample (Burlington:

245 +/- 85 pCi/L).

The analysis results were verified by a laboratory re-analysis. Statistically, the tritium levels observed were at the lower end of the vendor laboratory's counting system capability.

Required lower limits of detection were met. Additionally, radionuclides were not detected by the 1-131 or gamma isotopic analyses.

Activity due to plant operation was not evident in drinking water samples during 2005 and no unusual trends were noted.

(4) Shoreline Sediment Naturally occurring K-40 (10,382-10,953 pCi/kg, dry) was detected in samples obtained from the indicator location (DC) and in samples obtained from the control location (8,643-11,846 pCi/kg, dry). K-40 was also detected during pre-operational shoreline sediment monitoring.

Cs-137 activity was detected in the samples obtained from the control location (JRR). The indicator location (DC) samples did not have Cs-137 activity detected.

Required lower limits of detection were met. Activity due to plant operation was not evident in shoreline sediment samples during 2005 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.

(2) Fish Naturally occurring K-40 activity was detected in all fish samples.

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

During 2005, fish were also analyzed for tritium. All fish samples taken from Coffey County Lake had tritium activity detected (7,699.7 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 2005 (9,479 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.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 30

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.

The ODCM required lower limits of detection were met and no unusual trends were noted.

Activity attributable to plant operation was not detected.

(4) Crop Samples Gamma analysis detected naturally occurring K-40 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.

The ODCM required lower limits of detection were met 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. K-40 activity was also detected during pre-operational bottom sediment monitoring.

Co-60 activity (159.7 and 182.8 pCi/kg) was detected in the samples 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 environmental monitoring and was not detected in samples collected from control location JRR during 2005.

Chart 6 plots the Co-60 detected activity from the discharge cove and reflects a decreasing trend.

Cs-137 activity (208.9 and 234.4 pCi/kg) was detected in the indicator 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 2005 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 45 to 542 pCi/kg.) Cs-1 37 activity has been identified in plant effluents. Cs-137 activity (154.5 and 127.6 pCi/kg) was also detected in the control location samples and in the samples obtained from the indicator location EEA (83.7 and 77.3 pCi/kg).

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 trend line indicates that as expected, Cs-137 activity detected at the JRR control location has been decreasing.

2005 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 30

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

(2) Aquatic Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2005. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected in aquatic vegetation samples and no unusual trends were noted.

(3) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2005. No other radionuclides were detected. No unusual trends were identified.

(4) Soil Naturally occurring K-40 activity was detected in both of the soil samples. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 (557.5 pCi/kg) activity was detected in one soil sample obtained from the indicator location EEA. The pre-operational Cs-137 results (255 to 2,160 pCi/kg) for soil samples were decay corrected.

The decay corrected pre-operational range is approximately 160 to 1355 pCi/kg. The measured Cs-137 activity of the soil samples obtained during 2005 are within the decay corrected pre-operational range.

Cs-137 activity was not detected in air samples collected during 2005.

The measured Cs-137 activity in the soil sample was likely due to previous fallout and not to a recently produced fission product associated with plant operation.

No unusual trends were identified.

Ill. PROGRAM REVISIONSICHANGES No sample locations were changed during the 2005 monitoring period.

IV. PROGRAM DEVIATIONS Air Samples The air sample locations listed below failed to meet the requirement for 'continuous sampler operation." As described in footnote (1) of AP 07B-004, 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 Meter Time, which resulted in a loss of air sample collected, are listed in the following table.

V. INTERLABORATORY COMPARISON PROGRAM RESULTS During 2005, 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 0.286 mRem for 2005.

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 (12,855 pCi/L), would receive a committed effective dose equivalent of 0.587 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (7,699 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 0.597 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 Annual Radioactive Effluent Release Report, would compare directly to those calculated from the REMP. The Annual 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, 2005 through December, 2005

ApDendix A Interlaboratorv 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.

The results in Table A-2 list 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 Ospiked' 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 Oblank" samples for the past twelve months.. Data for previous years available upon request.

Table A-5 list results of 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. Data for previous years available upon request.

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

Attachment A lists acceptance criteria for *spiked samples.

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

EXECUTIVE

SUMMARY

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed for 2005 in accordance with AP 07B-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].

Changes are not required for the Radiological Environmental Monitoring Program (REMP) broadleaf vegetation sample locations for 2006. The two broadleaf vegetation locations with the highest calculated annual average D/Q rankings remain Gl.56-QURD1384 and Q2.35-MILA1619. AP 07B-004 specifies that an "alternate location may be used to provide continued monitoring". The third-ranked garden is location N2.38-RRDR9 and it will continue to be the alternate sample location.

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 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 five 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.

2005 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.

As identified in Table 2, sector "F" was the only sector that experienced a change in the nearest residence. The residence located at F1.57-14RD1711 is currently vacant, thus, the nearest residence in sector "F" is now Fl.76-14RD1730.

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

These changes are identified in Table 3.

There were no changes regarding milk locations. Again, no locations were identified that produced milk for human consumption.
