I. INTRODUCTION The Nuclear Management Company, LLC (NMC) Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Nuclear Plant (PNP) Radiological Environmental Monitoring Program as conducted -

during the 2004 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)

(monthly and quarterly) 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. The second criterion is the evaluation level (twice the statistical difference), which 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. Well water, lake water, sediment, fish, and other aquatic biota samples were evaluated using data mean comparisons against an appropriate control location (if available) and the PNP Offsite Dose Calculation Manual (ODCM), Appendix A, limits.

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

Ill. DISCUSSION AND INTERPRETATION OF RESULTS A. Air Samples There were 633 air samples collected and analyzed for gross beta and 1-131. Two samples were not included in the data comparisons because samples were 'light," indicating that the filters were installed off center in the sample head. Refer to Attachment A for sample collection anomaly evaluations.

Page 1 of 11

Air iodine/particulate samples are collected weekly from 12 air-sampling locations. Air is metered into the sampling unit at a continuous one cubic foot per minute flow rate (approximately) 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 nine near-site indicator locations and the three control locations, demonstrated that they were statistically different. However, the control mean was greater than the site mean. The mean values of ross beta results for indicator and control locations were 0.0261 pCi/m , and 0.0271 pCi/M3 , respectively. In 2004, control station 10-GR had the highest annual mean for gross beta results at 0.0272 pCi/M3 . No trends in gross beta results are discernable when compared to previous years' sample results.

No sample analyses identified 1-131 activity above minimum detectable levels.

B. Lake Water Palisades Lake-in, South Haven Municipal, and Ludington Lake-in water samples are collected daily for composite into a monthly sample. One gallon of Palisades Lake-in water and Ludington Lake-in water, and two gallons of South Haven Municipal raw water are sent to Environmental, Inc., Midwest Laboratory for analysis. No treatment of the water samples with preservative is required.

There were thirty-six monthly lake water composite samples collected from three locations during 2004. Lake water samples from the indicator locations, Palisades Lake-in (1-ST Intake), South Haven Municipal water system intake (25-SH Raw water), and the control location Ludington Lake-in (32-LP Intake), were collected daily.

Gross beta analyses were completed for all lake water samples.

Statistical analysis of the sample data, between the two site indicator locations and the control location, demonstrated that they were statistically different. However, the control mean was greater than the site mean, 2.3 pCi/L and 2.0 pCi/L, respectively. The results were also evaluated against the PNP ODCM, Appendix A, reporting limits. No limits were exceeded. No trends in gross beta results are discernable when compared to previous years' sample results.

C. Drinking Water Water samples from South Haven Municipal Water System (25-SH Raw Water, 25-SH Treated), and Ludington Lake-in (32-LP Intake), are collected daily for composite into a monthly sample. One gallon of Ludington Lake-in water, and two gallons each of South Haven Municipal treated and raw water are sent to Environmental, Inc., Midwest Laboratory for analysis. No treatment of water samples with preservative is required.

Thirty-six monthly drinking water samples were collected from the three locations in 2004.

Statistical analysis of the drinking water sample data, between the two indicator locations and the control location, demonstrated that they were statistically different. However, the control mean was greater than the indicator mean. The results were also evaluated against the PNP ODCM, Appendix A, reporting limits. Both of the South Haven Municipal lake water intake and treated drinking water samples require gross beta analyses. A tritium analysis is required for the treated water only. The gross beta mean values for the indicator and control locations were 1.9 pCi/L and 2.3 pCi/L, respectively. Tritium was detected in South Haven treated water on six samples during the months of March - August, with an average mean value of 528 pCi/L.

D. Milk Milk samples are required monthly from each designated location. Two one-gallon quantities of raw milk (grab sample) are obtained per sample location from dairy milk holding tanks. Each sample quantity is treated with a sodium bisulfate (40 grams per gallon) preservative prior to being sent to Environmental, Inc., Midwest Laboratory.

Forty-eight monthly milk samples were collected from four different dairy farms (stations 26-JH, 27-DH, 28-DC and 29-WS) during 2004.

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

E. TLDs - Gamma Dose Environmental gamma doses are measured monthly, quarterly, and annually, by placement of three TLD badges per designated location.

Each TLD badge contains a 4-zone Calcium Sulfate (CaSO 4 ) wafer (the wafer includes an additional backup/reserve readout zone). Sensitivity for the multi-zone TLDs is 1.0 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 30t 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 347 monthly, 116 quarterly and 29 annual TLDs collected and analyzed during 2004. During July 2004, the three TLDs (annual, quarterly, and monthly) at inner ring station number 20 were found missing during a monthly collection on July 30, 2004. This resulted in no data for the July monthly reading. New TLDs taken from the spares were installed to replace the missing quarterly and annual TLDs. However, these two TLDs (when collected and read) were not included when calculating the quarterly and annual means. Refer to Attachment A for sample collection anomaly evaluations.

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 2004, the average gamma readings (mR) were:

Location Monthly Quarterly Annual Inner Ring 3.79 11.90 42.62 Outer Ring 4.48 13.52 48.94 Control 4.84 13.84 50.07 The one on-site TLD location (1-ST) serves as an individual reference TLD; however, it was evaluated along with the inner ring (site boundary)

TLDs in the statistical evaluation.

The highest site monthly, quarterly and annual doses were observed at outer ring station number 2 (5.6 miles south) at 5.9, 16.3 and 58.8 mrem, respectively.

Page 4 of 11

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 means. No trends are discernable when comparing inner ring with outer ring and control TLD results in monthly, quarterly or annual sample 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.

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

While there are no designated locations where food crops are collected, samples are generally obtained from the same areas where the air monitoring stations are located within the ESE, SE or SSE sectors. The collection of food crops assists in verifying stack effluent deposition patterns. When 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.

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

Evaluation of the crop sample analytical results was based on a data means comparison between the indicator location and the control location, as well as a comparison to the PNP ODCM, Appendix A, reporting limits.

Of the radionuclide analyses listed in Table HP 10.4-2, only gross beta analysis resulted in any detectable activity. The gross beta mean values for the indicator and control locations were 0.71 pCi/L and 0.81 pCi/L, respectively. Based on the number of samples collected, and the minimal difference in activity between the controls and indicator locations, no statistical difference can be discerned.

G. 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.

Ten sediment samples were collected from three locations during 2004.

Eight sediment samples were obtained from Palisades [1-ST discharge, 31-STS (0.5 miles south of discharge), 30-STN (0.5 miles north of Page 5 of 11

discharge), and 25-SH (South Haven beach)] locations and two samples from the Ludington Control Station (32-LP).

The evaluation of the sediment analytical results was based on a data means comparison between Palisades and Ludington control samples, as well as the PNP ODCM, Appendix A, reporting limits. Of the radionuclide analyses listed in Table HP 10.4-2, only gross beta was detectable. The gross beta mean values for indicator and control locations were 7.79 pCi/g and 9.23 pCi/g, respectively. No trends for gross beta results are discernable when compared to previous years' sample results.

H. 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 either frozen, or treated with a ten percent formaldehyde solution for preservation.

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

and one from the St Joseph vicinity. The same species were collected at both indicator and control locations during each of the two collection periods.

Evaluation of the fish analytical results was based on a data means comparison between the Palisades and Ludington control samples, as well as with the PNP ODCM reporting limits. The gross beta mean values for indicator and control locations were 2.25 pCi/g and 3.04 pCi/g, respectively. Cs-137 was the only gamma emitter detected and only at the Ludington Station. The mean was 0.039 pCi/g. No trends in Cs-1 37 are discernable when compared to previous years' sample results. No trends for gross beta results are discernable when compared to previous years' sample results.

I. Broad Leaf Vegetation No broad leaf vegetation samples were collected from the surrounding PNP environs during 2004. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling media in case any milk sampling location(s) become(s) unavailable.

Page 6 of 11

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

K. Gaseous and Liquid Radwaste Effluent Composite Samples Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Environmental, Inc., Midwest Laboratory 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.

For those months in which there were no liquid batch effluent releases, no sample is sent to Environmental, Inc., Midwest Laboratory. 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 2004 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.

Table 10.11-3 lists the critical receptor locations used in calculation of the offsite doses by the GASPAR computer program.

There are two changes to critical receptor locations from the 2003 Land Use Survey.

Goats and beef cattle were found in a new location, at the SE sector at 1.9 miles. This will change the X/Q value for goats from 2.14E-07 to 2.32E-07. This will change the X/Q value for beef cattle from 1.86E-07 to 2.32 E-07. As a result of these two critical receptor changes, Design Basis Quantities (DBQ) for 1-131, Cs-1 36, Nb-95 and Rul 03 will decrease. DBQ changes will be documented in a subsequent memo.

Tables 10.11-1 and 10.11-3 will be updated in the ODCM as Tables 1.4 and 1.4a respectively. Attached to this report are the new revisions of Tables 1.4 and 1.4a. The ODCM revision is in progress.

Inaddition, I requested Air Improvement Resource, Inc. (Dennis Kahlbaum) to run computer code XOQDOQ82, using the 1999 - 2003 met data, in conjunction with the critical receptor, to determine if X/Q values had significantly changed. The following table compares existing data with the results of this run, with the most conservative value listed in bold.

Location Current X/Q Calculated X/Q (met data 1/92 - 12/96) (met data 1/99 - 12/03)

site boundary data used in all effluent calculations

Currently Palisades uses the 1992-1996 met data due to it being conservative when compared to more current met data. In a comparison of the 1992-1996 met data, with the most current met data, the results show that the site boundary X/Q currently used is within 4.5% of the most current met data. The other critical receptors comparisons are nearly identical. Based on this comparison, I recommend continued use of the 1992-1996 met data.

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 8 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.

e. Air station leakage shall be none detectable. If the replacement of air station components is required due to air leakage, document on air sample collection data sheet.

5.2.2 Prerequisites

a. Glass fiber (particulate) air filters

b. Charcoal cartridges for iodine sampling (prelabeled for each air sampler)

c. Glassine or plastic envelopes (prelabeled for each air sampler)

d. REMP Air Sample Data Sheet (containing installation data)

f. Tweezers

9. Stop Watch

h. Step Ladder NOTE: The Control Stations 1O-GR, 1-KZ, are changed out weekly by independent collectors, and mailed in separately. The prelabeling of cartridges and envelopes, detailed below, is not required for these stations as sample mix-up is not possible.

In addition, for these control stations, the Palisades Sample Collection Form and Records (Page 1 of Attachment 5) is completed by the Technician changing out the ten local stations by transferring the recorded data provided by the independent collectors.

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.

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

PALISADES NUCLEAR PLANT Proc No HP 10.10 HEALTH PHYSICS PROCEDURE Revision 8 Page 6 of 14 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT

h. Clean out any residue or moisture buildup in sampler head before replacement filter is installed. Check the condition of the sampler head 0-rings. Replace cracked 0-rings as necessary to prevent air leakage.

i. 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.

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, 2004

ADDendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services 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.

The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Attachment A lists acceptance criteria for 'spiked" samples.

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

Midwest Laboratory as a participant in the Department of Energy's Mixed Analyte Performance Evaluation Program, Idaho Operations office, Idaho Falls, Idaho b Results are reported in units of Bqlkg (soil), Bq/L (water) or Bq/total sample (filters, vegetation) as requested by tt Department of Energy.

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

d The cause of the deviation seems to be Incomplete dissolution of the sample.

o A spiked soil sample was prepared. Known activity; 32.98 pCi/g; laboratory result 33.47 pCi/g.

The sample was reanalyzed with the same results. Investigation is in progress.

° Based on the results of gamma emitting isotopes (Cs-1 37 and Co-60), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results in a recalculation of 2.12 +/- 0.15 Bq/sample.
