I. INTRODUCTION The Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Nuclear Plant (PNP) Radiological Environmental Monitoring Program, as conducted during the 2006 reporting period. This report was prepared in accordance with the requirements of 10 CFR 50, Appendix I, Sections IV.B.2, IV.B.3, IV.C, and Technical Specification 5.6.2.

Detailed sample station identification and location information can be found in Attachment 2 of Health Physics Procedure HP 10.10, "Palisades Radiological Environmental Program Sample Collection and Shipment." HP 10.10 is included as Attachment C. The results of all environmental samples collected are evaluated as follows:

A. Air iodine and particulate and thermoluminescent dosimetry (TLD) data were statistically evaluated at the 95% confidence level. The data were compared against two criteria. The first criterion is the statistical difference, which indicates whether the sample results from near sites are greater than those from control sites, and whether or not the difference is significant (e.g., statistical "T-Test" of indicator vs. control results).

If the T-Test concludes that the control and indicator populations are statistically different and the indicator populations are higher, then the evaluation level (twice the statistical difference) is computed. This is the minimum difference in the population means for which a corresponding difference in sample means will exceed the statistical difference with 95%

confidence. If the evaluation level is exceeded, then correlation of the results with effluent releases is performed.

B. If a sufficient number of positive sample results were available (e.g., >1 control and > 1 indicator) then well water, lake water, sediment, fish, and other aquatic biota samples were evaluated using data mean comparisons and the PNP Offsite Dose Calculation Manual (ODCM),

Appendix A, reporting limits.

I1. NON-ROUTINE REPORTS Non-routine reportable events did not occur during this reporting period.

III. DISCUSSION AND INTERPRETATION OF RESULTS A. Air Samples There were 258 air samples collected and analyzed for gross beta and 1-131. Air iodine/particulate samples are collected weekly from five air-sampling locations. Air is metered into the sampling unit at an Page 1 of 10

approximate one cubic foot per minute flow rate through a Radeco 47-mm air filter (air particulate) and a HI-Q air iodine cartridge. Both filters are in-line with each other and housed within the same filter holder. Weekly samples were sent to Environmental, Inc., Midwest Laboratory for analysis.

Statistical analysis of the airborne particulate sample data, between the four near-site indicator locations and the control location, demonstrated no statistical difference. The mean values of gross beta results for 3 , and 0.028 pCi/m 3, indicator and control locations were 0.026 pCi/m respectively. The control station 10-GR had the highest annual mean for gross beta results at 0.028 pCi/m 3 . No trends in gross beta results are discernable when compared to previous years' sample results.

All 1-131 activity results were below the Minimum Detectable Activity (MDA) levels.

B. Lake Water (Surface Water)

Palisades lake water inlet, South Haven Municipal Raw and Ludington lake water inlet water samples were collected daily and combined into monthly composite samples. One gallon of Palisades Lake-In (1-ST) and Ludington Lake-in (32-LP) and two gallons of South Haven Municipal Raw (25-SH) were sent to Environmental, Inc., Midwest Laboratory for analysis each month. No treatment of the water samples with preservative is required. Thirty-six monthly lake water composite samples collected from the three locations were analyzed for gross beta and tritium.

No statistical difference was found between the indicator and the control location samples and no PNP ODCM Appendix A reporting limits were exceeded.

C. Drinking Water Water samples from South Haven Municipal Water System (25-SH Treated), and Ludington Lake-in (32-LP), were collected daily and combined into separate monthly composite samples. (The South Haven Treated is obtained at the PNP site.) One gallon of the Ludington Lake-in and South Haven treated samples (twenty-four total) were sent to Environmental, Inc., Midwest Laboratory for beta and tritium analysis. No treatment of water samples with preservative is required.

No statistical difference was found in the beta results between the indicator and the control location samples and no PNP ODCM Appendix A reporting limits were exceeded.

D. Well Water Two one-gallon well samples are taken quarterly from each of the three monitoring wells adjacent to the steam generator storage facility (41 -ST, 42-ST and 43-ST). Twelve total samples were sent to Environmental, Inc.,

Midwest Laboratory for beta and tritium analysis. No treatment of water samples with preservative is required.

Tritium was detected in the fourth quarter well # 15 sample (42-ST) at a level of 300 pCi/L. A gross beta value of 11.4 pCi/L was detected in the third quarter well # 16 sample (43-ST). As this value was greater than 10 pCi/L, a follow up gamma analysis was performed, and showed less than minimum detectable activity values for gamma emitters. Note that these wells are not associated with any drinking water supply.

E. Milk Two one-gallon quantities of raw milk (grab sample) are obtained per sample location per month from dairy milk holding tanks. Each sample quantity is treated with a sodium bisulfate preservative prior to being sent to Environmental, Inc., Midwest Laboratory for analysis.

Forty-eight monthly milk samples were collected from the four dairy farms (stations 26-JH, 27-DH, 28-DC and 29-WS).

No milk analysis identified activity above the minimum detectable level, with the exception of naturally occurring potassium-40.

F. TLDs - Gamma Dose Environmental gamma doses are measured quarterly by placement of TLDs at each designated location. Each TLD badge contains a 4-zone Calcium Sulfate (CaSO4 ) wafer (the wafer includes an additional backup/reserve readout zone). Sensitivity for the multi-zone TLDs is 10 millirem, with a linear response of 0.1 millirem to 1000 rem.

The PNP gamma assessment program consists of 29 locations. There is a total of 16 inner ring TLDs, including one on-site, nine near-site and six steam generator storage facility locations. There are ten outer ring TLD locations (1.0 to 5.5 miles out) and three control TLDs (30 to 55 miles out). A 30 h TLD is placed in a lead storage cave (location number 22),

and is used as a control for in-transit dose monitoring and subtraction.

There were 115 TLDs collected and analyzed during 2006. The one on-site TLD location (1-ST) serves as an individual reference TLD; however, Page 3 of 10

it was evaluated along with the inner ring (site boundary) TLDs in the statistical evaluation.

The TLD data evaluations were performed by comparing the inner ring TLDs (site boundary locations 1, 13-21 and 33-38), and the outer ring TLDs (locations 2-9, 23 and 24), against the control TLD locations (10, 11, 12).

For 2006, the quarterly average gamma readings (mR) were Inner Ring -

12.5, Outer Ring - 14.5 and Control - 14.8 The highest average dose was observed at outer ring station number 2 (5.6 miles south) with a dose of 17.6 mrem.

Statistical analysis demonstrated that inner ring vs. control TLDs were two different populations. However, the control mean was greater than the inner ring mean. There was no statistical difference between the outer ring and control populations. No trends are discernable when comparing inner ring with outer ring and control TLD results. Overall, outer ring TLD mean results are consistently higher than inner ring TLD mean results, and control station TLD mean results are slightly higher than outer ring mean results. (The likely reason for the lower results seen for the site perimeter locations is that these TLDs are placed in wooded areas and thus shielded to some degree from cosmic background radiation.)

G. Crops Food crop samples are collected when available, and in season. Two principal area crops, apples and blueberries, are regularly collected.

Approximately 1 kg of sample is placed in a sealable plastic bag for shipment to Environmental, Inc., Midwest Laboratory. No special treatment of the samples with a preservative is necessary.

Three crop samples were collected. Blueberries and apples were collected at indicator station 4-JS (3.5 miles SE), and apples at a control station located in the least prevalent wind direction, approximately 11 miles NNE. (Control blueberries were lost during shipment.),

No crop analysis identified activity above the Minimum Detectable Activity for either 1-131 or gamma emitters.

Page 4 of 10

H. Sediment Sediment samples are collected semi-annually from each designated location. No treatment of the samples with a preservative is necessary prior to shipment to Environmental, Inc., Midwest Laboratory.

Four sediment samples were collected from two locations. Two were obtained from Palisades, 30-STN (0.5 miles north of discharge), and two from the Ludington Control Station (32-LP).

No sediment analysis identified any gamma activity.

1. Fish Fish samples are collected semi-annually. Samples consist of two species of commercially and/or recreational important species near the plant discharge area. One sample of the same species in an area not influenced by plant discharge is collected. Each one-liter quantity of fish sample is prepared for shipment to Environmental, Inc., Midwest Laboratory. Each sample is frozen for preservation.

Seven individual fish samples were collected from two locations. Three indicator samples were obtained from Palisades (1-ST discharge) and four control samples were obtained from Ludington Station (32-LP).

Cs-137 was the only gamma emitter detected and was seen in two indicator samples and two control samples. The average values were 0.049 pCi/g and 0.044 pCi/g respectively. No trends in Cs-137 are discernable when compared to previous years' sample results. The ODCM reporting limit for Cs-137 is 2000 pCi/kg (2 pCi/gm).

J. Broad Leaf Veqetation No broad leaf vegetation samples were collected from the surrounding PNP environs during 2006. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling medium in case any milk sampling location(s) become(s) unavailable.

K. Non-Routine Samples There were no non-routine samples collected during this reporting period.

Page 5 of 10

L. Gaseous and Liauid Radwaste Effluent Composite Samples Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Teledyne Brown for analysis. No special sample treatment with a preservative is required prior to laboratory analysis. The liquid effluent composite sample is based on a specific amount of sample collected, per total batch volume release. The gaseous radwaste effluent weekly composite sample results are based on analyzing weekly stack gas filters.

Although not a direct reporting component in the PNP Annual Radiological Environmental Operating Report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. This evaluation is the basis for determining isotopic dispersion and deposition patterns within the surrounding environs of PNP. All gaseous and liquid effluent results are compared to the PNP ODCM, Appendix A, reporting levels. All isotopic lower limits of detection (LLDs) were met.

IV. ASSESSMENT OF PALISADES OPERATION ENVIRONMENTAL IMPACT In reviewing the 2006 PNP radiological environmental monitoring data, and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of PNP has minimal environmental impact. Most isotopic activity is at environmental background levels. Evidence of an overall environmental isotopic buildup (attributable to plant effluents) remains negligible as well. In most instances, sample analytical results were below previously established environmental background levels.

5.1 CONTROL AND OVERSIGHT OF SAMPLING FOR THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 5.1.1 Sampling techniques described by this procedure must be strictly adhered with.

a. This includes use of tweezers for air sample media change out to ensure the collected media is not disturbed.

b. Recorded data should be verified including verification of transcribed data to avoid errors.

c. All deviations from performance requirements, unavailable samples, or other sampling anomalies must be reported to the C&RP Radiological Environmental Contact.

5.1.2 Failure of sample collectors to comply with sampling and reporting requirements may result in remedial training, or reassignment of sampling duties.

5.1.3 The C&RP Radiological Environmental Contact shall conduct periodic (annual) audits of air sampling activities performed by non-Palisades C&RP personnel.

a. These audits shall include observation of collection techniques, verification of procedural compliance, and review of equipment condition.

Included in the review of equipment condition, is to ensure that any fast growing trees and bushes in the vicinity of the station are removed, along with any branches extending over the top of the sampler. The goal is to keep every station away from the drip line (with the exception of station 9, which has an existing canopy 50 feet above the station).

b. Audits should specifically address air sample collection and should include observation of all individuals involved in sample changeout.

PALISADES NUCLEAR PLANT Proc No HP 10.10 HEALTH PHYSICS PROCEDURE Revision 9 Page 4 of 14 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT

c. Results of the audits and any follow up action should be documented in the REMP file.

Collect samples using the following methodology in accordance with schedule and location data described in Attachments 1 and 2.

5.2 REMP AIR SAMPLE COLLECTION 5.2.1 Precautions

a. New filters and cartridges should be transported and handled such that potential contamination of them is minimized (ie, placed in clean plastic bags, etc).

b. If an air sampling unit is discovered not operating, attempt to find the cause and repair. If this cannot be done, replace applicable component and document on air sample collection data sheet.

c. Airflow meters shall be calibrated annually by General Meter. All in service calibrated meters will have affixed a valid calibration sticker/card stating date of calibration and calibration due date.

d. Airflow meters shall be changed out prior to the expiration of calibration dates.

g. Stop Watch

h. Step Ladder NOTE: The Control Station 10-GR, is changed out weekly by an independent collector, and mailed in separately. The prelabeling of cartridges and envelopes, detailed below, is not required for this station as sample mix-up is not possible. In addition, for control station, the Palisades Sample Collection Form and Records (Page 1 of Attachment 5) is completed by the Technician changing out the four local stations by transferring the recorded data provided by the independent collector.

5.2.3 Perform the following weekly at each sample location:

a, Open the protective cover on the air sample station and verify the sampling location number written on the inside of the door is the same as the prelabeled sample change-out package.

b, Verify that the meter serial number and calibration due date are correctly documented on Palisades Plant Environmental Monitor Operability Check and Sample Collection data form (Page 1 of Attachment 5).

c, Determine and record the "As Found Flow" rate (seconds for one cubic foot of volume).

d. Determine and record the "As Found Leak" rate by placing hand over filter housing inlet to form a seal. While holding hand over the inlet, determine if air leakage is evident by checking the air flow meter needle for movement (leakage). If no air leakage, record (N) in the "As Found Leak" column. If air leakage is indicated, determine the cause and repair as soon as possible.

e. Unplug or turn off the air pump and record the "REMOVED MONTH/DAY/YEAR," "REMOVED TIME," and "GAS METER READING REMOVED."

f. Remove the prelabeled charcoal cartridge and place in zip lock bag.

g. Using tweezers, carefully remove particulate filter from the sampler head and place in the prelabeled glassine envelope or plastic envelope.

h. Clean out any residue or moisture buildup in sampler head before replacement filter is installed. Check the condition of the sampler head o-rings. Replace cracked o-rings as necessary to prevent air leakage.

PALISADES NUCLEAR PLANT Proc No HP 10.10 HEALTH PHYSICS PROCEDURE Revision 9 Page 6 of 14 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT Install new particulate filter and charcoal cartridge and ensure that both are properly centered in sampler head to prevent air leakage. Ensure the fiber side of the particulate filter is facing out (smooth side facing inward).

j. Restart air pump. Place hand over the filter housing inlet to form a seal, determine if air leakage is evident by checking air flow meter needle movement. If no air leakage, record (N) in the "As Left Leak" column. If air leakage indicated, determine the cause of the leakage (filter not centered in holder properly or cracked o-ring) and correct problem as soon as possible, restoring system to no air leakage.

k. Determine and record "As Left" flow rate. If greater than 90 seconds are required for one cubic foot of volume, the sample pump is degrading.

Replace pump as soon as possible to avoid failure to reach minimum sample volume. (5000 ft3 ).

1. If an airflow meter must be replaced, record this in the "Comments" column.

Record replacement meter data in the reading on the upcoming week's sample collection data sheet.

m. Close the protective cover on the air sample station.

n. Proceed to the next station. Date and sign the current week's data sheet upon completion of the entry of all current data.

o. Calculate and record "SAMPLE VOL (FT3)," ALSO ensure all pertinent data is recorded.

p. Transcribe the "REMOVED MONTH/DAY/YR" and "GAS METER READING REMOVED" taken in Step 5.2.3e to the "INSTALLED" reading columns on the sample collection sheet to be used for the upcoming week's air sample collection. Also transcribe the meter serial number and calibration due date to the upcoming week's sample collection sheet.

1. Label samples clearly per Attachment 3.

2. Seal all liquid, biota, fish, and sediment sample containers with tape to prevent leakage.

3. Ship liquid samples separately from air particulate and air iodine samples and TLDs.

4. Use sufficient packing material (ie, crumpled newspaper) to avoid possible sample container damage during shipment.

5. Package air filters in glassine or plastic envelopes.

6. For TLD shipments, make sure that laboratory contractor's own TLD data sheet is enclosed with package.

7. Ship milk samples as soon as possible. Be sure to add a sufficient amount of sodium bisulfite (40 grams) as preservative to each sample.

8. Ship food products as soon as possible after collection.

9. Ship fish frozen or packed in ice, or with a 10% formaldehyde solution added (preservative). Only 10 milliliters is required per sample. Samples should be shipped as soon as possible after processing.

10. Distribute copies of the Sample Collection Data Sheet(s) to the:

Analytical Laboratory Radiological Services Department Environmental Contact (Palisades)

11. Send samples to the following address:

Environmental Inc.

Att: Laboratory Manager 700 Landwehr Road Northbrook, IL 60062

12. Ship all samples to the laboratory contractor with minimal delay after collection so as to avoid elevated analytical levels of detection.

1.0 INTRODUCTION

The following constitutes the final 2006 Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the Consumers Energy Company, Palisades Nuclear Generating Plant. Results of completed analyses are presented in the attached tables.

For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 KeV.

Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Ba-La-140, Cs-134 and Cs-137. Naturally-occuring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but not listed here. Data listed as "<" are at the 4.66 sigma level, others are 2 sigma.

All concentrations, except gross alpha and gross beta, are decay corrected to the time of collection.

All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.

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; xi +/- sl and X2 +/-s2 Reported result: x +/--s; where x = (1/2) (xi + x2) and s = /(1i2) 21 2 3.2. Individual results: <L1 , <L2 Reported result:!<L;,whereL=.lower of.-Ll andL2 3.3. Individual results: x +s, <L Reported result: . x +/- sifx _>L;,<otherwise.

4.0. Computation of Averaaes 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 , x2 ... xn are defined as follows:

n= x~ n-1 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 number following those to be retained is less than 5, the number is dropped, and the retained number s are kept unchanged. As an example, 11.443 is rounded off to 11.44.

4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.

January, 2006 through December, 2006

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

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

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

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. 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.

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

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

e Included in the MAPEP as a false positive.

Difficulties with the analyses for transuranics isotopes in solid samples (Filters, Soil and vegetation),

were attributed to incomplete dissolution of the samples. Soil samples were repeated, results of reanalyses:

Pu-238, 53.1 +/- 5.3 bq/kg. Pu-239/240, 42.4 +/- 4.7 bq/kg. U-233/4, 33.3 +/- 3.5 bq/kg. U-238, 35.5 +/- 3.6 bq/kg.

g The July vegetation sample was provided in two separate geometries, (100 ml. and 500 ml.). Results reported here used the 500 ml. standard size geometry. Results for the 100 ml. geometry showed approximately a 15% higher bias.
