The REMP is a requirement of the Fort Calhoun Station (FCS) operating license. It was initiated prior to plant operation in 1973.The main purpose of the REMP is to ensure public safety by monitoring plant discharges and assessing the effect, if any, of plant operations, on the environment.

Samples are collected that would account for various exposure pathways such as ingestion, inhalation, adsorption and direct exposure.Samples collected on a regular basis include: air, water, milk, vegetation, fish, sediment, and food crops. Direct radiation is measured by thermoluminescent dosimeters (TLDs). These samples and TLDs are sent to an independent vendor laboratory for analysis.

The vendor uses analytical methods that are sensitive enough to detect a level of activity far below that which would be considered harmful. Locations for sample collection are based on radiological and meteorological data from the Annual Effluent Release Report and information obtained from the Environmental Land Use Survey.Most samples, particularly indicator samples, are collected in a circular area within a five-mile radius of plant containment. (However, control locations are usually outside of five miles.) This circle is divided into sixteen equal sectors, each assigned an identification letter "A" through "R" (note: letters "I" and SO" are not used, as they may be mistaken for the numbers UI " and "0"). Sector "A" is centered on North or zero degrees. Sectors are also given directional labels such as "West-Southwest" ("WSW"). Sample locations are listed by number along with their respective distances and direction from plant containment, in the Offsite Dose Calculation Manual (ODCM).When assessing sample results, data from indicator locations (those most likely to be affected by plant operations) are compared to those from control locations (those least or not likely to be affected).

Results from an indicator location which were significantly higher than those from a control location, could indicate a plant-attributable effect, and could require additional investigation.

The results of the sample analyses, as required by the FCS Offsite Dose Calculation Manual (ODCM), are presented in the attached statistical tables in accordance with Table 1 of Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants." Sample collection was conducted by plant chemistry/environmental staff. A contract vendor (Environmental Inc., Northbrook, Illinois) performed sample analyses, preparation of monthly reports and the statistical evaluation of sample results. All vendor analysis techniques met the sensitivity requirements as stated in the ODCM.Page 2 of 10 Results for 2005 were within expected ranges and compared closely with historical results. The following is a review of specific sample results.1) Ambient Gamma Radiation Ambient gamma radiation is measured by thermoluminescent dosimeters (TLDs) provided by the vendor laboratory.

These dosimeters contain calcium sulfate phosphors and are processed quarterly.

All results for 2005 were within historical ranges. The indicator locations had annual means ranging from 1.2 to 1.6 mrem per week. The control location (OTD-L) had an annual mean of 1.3 mrem per week. Results from indicator locations are within the range of results from the control location.

No plant-attributable results were observed.2) MilklPasture Samples Milk samples are collected every two weeks from the beginning of May through September.

Indicator samples are collected from a herd of milk goats at a family farm located approximately

0.7 miles

from the plant in Sector K (South-Southwest).

The control samples are collected from a commercial dairy cow herd located approximately

9.9 miles

from the plant in Sector J (South). These locations are unchanged from last year. There were no missed milk samples this year, therefore, no pasture samples were needed.All milk sample results for lodine-1 31, Cesium-1 34, Cesium-1 37 and other gammas were less than LLD for both indicator and control locations.

No plant-related effects were observed.3) Fish Fish are collected on an annual basis. Control samples are collected at a location approximately twenty miles upstream of the plant (river miles 665-667). Indicator samples are collected in the immediate vicinity of the power plant (river miles 644-646).

Several species of fish, important to commercial and recreational interest, representing all levels of the aquatic food chain are collected at both locations.

Results from both locations were less than LLD for all gamma emitters, indicating no plant-related effects.4) Food Crops Vegetable garden locations remain unchanged from last year. The indicator and control locations for gardens are the same as for milk samples. Vegetables collected include rhubarb, green beans, tomatoes, corn, beets and pumpkin. All results were less than LLD for all isotopes.No plant-related effects were observed.Page 3 of 10

5) Sediment River sediment samples are collected twice a year at an upstream control location and a downstream indicator location.

All results were less than LLD, and no plant-related effects were observed.6) Air Monitoring Air sample results for 2005, were well within historical limits for all locations.

Additionally, all indicator locations showed results very similar to the control location.Three condition reports were written on location OAP-K-(I) in 2005. When samples were collected on April 20t, it was discovered that the ground-fault interrupt (GFI) circuit had tripped, although enough sample was collected (405 cubic meters) to determine activity of the sample and meet the required LLD. At the time, the ground-fault trip was thought to be an isolated incident.

When samples were collected on July 6t, the GFI was found to have tripped off again after about sixteen hours. This second incident prompted a more thorough investigation leading to the conclusion that the cause of the trip was water from heavy rains earlier in the week, accumulating in the bottom of the pump housing. This was considered a lost sample, and a work order was initiated to have drainage holes drilled in the floor of the housing. Two weeks later, on July 20th, the GFI again tripped after 108.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />, and in addition, it was noticed that some wiring on the back-up timer was done in such a way that moisture could affect it.Environmental personnel drilled drainage holes to remedy the problems with this location.

The run time of 108.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />, allowed a sample volume of 369 cubic meters to be collected, and the sample activity was calculated accordingly.

Although one sample was insufficient to meet LLD and two were of less than usual volume, there was no effect on public safety or the Public Radiation Cornerstone.

There were no significant airborne effluents during these time periods, and air monitoring done in the adjacent sectors showed results in the normal range.Problems with low sample volumes happened at three locations.

Air sample pumps are brought into the calibration shop every six months. If a pump is found to be out-of-tolerance in the shop, it is presumed to have gone out-of-tolerance as of the first day in the field and air sample volumes are calculated accordingly.

This yields the most conservative approach to monitoring any potential environmental impact.The air pump at location OAP-D-(I), City of Blair, had been in place from October 20, 2004, to April 13, 2005, when it was brought into the calibration shop where it was found to be reading 1.74 standard cubic feet Page 4 of 10 per minute (SCFM). The lower limit is 1.8 SCFM, the norm is 2.0 SCFM.Recalculating activity per weekly sample showed no unusual results.Location OAP-J-(l) also had a pump with a lower than expected flow when brought to the shop. This pump was in place from October 20, 2004, to April 20, 2005. The pump read 1.78 SCFM when checked in the shop.Again, sample volumes and activities were recalculated and no unusual results were found.The third location was OAP-F-(C), which is the control location at Valley.That pump was in the field from May 4, to August 31, 2005. When checked, the flow was determined to be 1.75 SCFM. Results were recalculated and showed nothing unusual. The two indicator locations, above, had results in the same range as the control location.A significant effort was made in the past year to identify the cause of this problem with low flow rates. The technicians researched thoroughly and were able to identify the carbon vanes, which act as impellers in the air pumps, as the most likely cause. Although the same type of air pump is used in the plant, with little problem, it is believed that conditions in the field cause more wear and aging to occur on the vanes. The pump calibration procedure has been re-written to include replacing the carbon vanes every six months. This replacement process has been underway for several months, and no new flow rate problems have been observed.7) Water Samples Water samples are collected upstream of the plant (control location) as well as a half-mile downstream, and at a municipal water treatment plant on the north edge of Omaha.First quarter composite results showed Tritium at 1268 pCiIL for location OSW-B-(I), which is 0.45 miles downstream of the plant. This is not unusual for first quarter samples. Tritium has been detected in other winter time water samples from previous years. River flow and volume are significantly less during the winter than in summer, which results in less dilution.

Liquid effluent releases from the plant occur at times during river sampling and therefore, positive identification of tritium is more likely on downstream samples at these times. There was no effect on public safety or the Public Radiation Cornerstone.

Environmental Inc.participates in interlaboratory comparison (crosscheck) programs, as part of its quality control program. These programs are operated by agencies such as the Department of Energy which supply blind-spike environmental type samples such as milk or water containing concentrations of radionuclides unknown to the testing laboratory.

This type of program provides an independent check of the testing laboratory's procedures and processes, and provides indication of possible weaknesses.

In addition, Environmental Inc. has its own in-house QA program of blind-spike and duplicate analyses.Of the more than 150 In-House duplicate samples tested by the vendor laboratory, three were listed as having failed. Two of these failed samples, one K-40 and one gross beta, were strictly the result of long count times, which yielded very low error results. Since these low errors did not overlap, they were listed as failed, though the duplicate reads were actually very close. The third failed sample was another gross beta analysis, and when counted a third time, met the acceptance criteria.The vendor laboratory participated in the Department of Energy's Mixed Analyte Performance Evaluation Program, correctly evaluating 68 out of 70 samples. One Sr-90 sample was read higher than the acceptance criteria.

When the strontium carbonate precipitates were re-dissolved and processed, the new results were within limits. The other sample that failed, an Americium-241 sample, was originally calculated using an incorrect sample weight. When the correct weight was used, the results were within limits.Out of the fifty-two samples tested as part of the Interlaboratory Comparison Program provided by Environmental Resource Associates, two were initially marked as failures.

The first, a gross alpha, was spiked with Thorium-232, but mistakenly calculated using an Americium-241 efficiency.

When the correct efficiency factor was used, the results were within limits. The other sample, Radon-228 failed the first time it was counted due to decay of short-lived radium daughters, which contributed to a higher counting rate. Delay of counting for 100 minutes provided satisfactory results.Chemistry evaluations of failed vendor QA concluded that REMP analyses were not affected as a result, and that the overall effectiveness of the REMP to monitor public safety was not reduced or compromised.

Vendors review of their results and corrective actions taken appear sufficient and will continue to be reviewed by OPPD environmental personnel.

Results are reported In Appendix A. TLD Intercornparlson 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 ComDarison Pro-gram 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 "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 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.

STAP (air filter), STSO (soil), STVE (vegetation).

d MAPEP results are presented as the known values and expected laboratory precision (I sigma, I determination) and control limits as defined by the MAPEP.The strontium carbonate precipitates were redissolved and processed.

The average of the three analyses was 1.34 1 although the recovery was only 30%. The result of a new analysis was 1.56 pCi/L.Incorrect sample weight used In calculation.

97.0 +/- 7.8 Bqlkg.A6-3 APPENDIX B DATA REPORTING CONVENTIONS B-1 Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.2.0. Single Measurements Each single measurement is reported as follows: x +/- s where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.3.0. Duplicate analyses 3.1 Individual results: For two analysis results; x1 +/- sl and X2 +/- 52 Reported result: x +/- s; where x = (112) (x1 + x2) and s = (1/2) \I 2 3.2. Individual results: <L1 , <L2 Reported result: <L, where L = lower of Li and L2 3.3. Individual results: x +/- s, <L Reported result: x +/- s if x 2 L; A otherwise.

4.0. Computation

of Averages and Standard Deviations

4.1 Averages

and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations.

The average x and standard deviation s of a set of n numbers x 1 , x 2 ... xn are defined as follows: X =- YX s=n ~ ~xs n-I 4.2 Values below the highest lower limit of detection are not included in the average.4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.4.5 In rounding off, the following rules are followed: 4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged.

As an example, 11.443 is rounded off to 11.44.4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.4.6 Composite samples which overlap the next month or year are reported for the month or year in which most of the sample is collected.
