PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT INTRODUCTION The 2001 Palisades Nuclear Plant Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Radiological Environmental Monitoring Program as conducted during the 2001 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 of Health Physics Procedure HP 10.10 (Enclosure C). The results of all environmental samples collected are evaluated as follows:

A.

Air iodine and particulate, and thermoluminescent dosimetry (TLD)

(monthly, quarterly and annual) data were statistically evaluated at the 95% confidence level. The data was 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 done.

B.

Well water, lake water, sediment, fish, and other aquatic biota samples were evaluated using data means comparisons against an appropriate control location (if available) and Palisades Offsite Dose Calculation Manual, Appendix A, limits.

NON-ROUTINE REPORTS No non-routine reportable events occurred during this reporting period.

III.

DISCUSSION AND INTERPRETATION OF RESULTS A.

Air Samples A total of 626 air samples were collected and analyzed for 1-131, and 625 air samples were collected and analyzed for gross beta. During the year, one of the particulate filters was lost in the handling process and was not 1

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT analyzed. In addition, one sample was not collected due to equipment problems. Refer to Enclosure A for all sample collection anomaly evaluations.

Air iodine/particulate samples are collected on a weekly basis from twelve air sampling locations. Air is metered into the sampling unit at a continuous one cubic foot per minute flow rate (approximately) through a Gelman 47mm 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 are sent to Environmental, Inc., Midwest Laboratory for analysis.

Comparison of the airborne particulate sample data between the nine near-site indicator locations, and the three control locations, did not exceed the statistical difference. In many instances, control location sample values were greater than indicator location samples. The mean values of gross beta results for indicator and control locations were identical at 0.028 pCi/m3.

When rounding to 5 significant numbers, the control station's results of 0.02777 pCi/m3 are slightly higher than indicator station's results at 0.02771. In 2001, station 11-KZ had the highest annual mean for gross beta results at 0.029 pCi/rn3. This is a control station located 35 miles east of the site. Overall, gross beta results are trending slightly higher for both indicator and control stations when compared to previous years. 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 each of South Haven Municipal treated and raw water are sent to Environmental, Inc., Midwest Laboratory for analysis. No treatment of the water samples with preservative is required.

A total of 36 individual monthly lake water composite samples were collected from three locations during 2001. 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.

Evaluation of the monthly lake water analytical results was based on a 2

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT data means comparison between the indicator locations and control location. The results were also evaluated against the Palisades ODCM, Appendix A, reporting limits.

Gross beta analyses were completed for all lake water samples. The mean values for gross beta indicators and controls were 2.2 pCi/L and 2.0 pCi/L, respectively. Tritium was detected in two indicator samples and one control sample at an average of 192 pCi/L, and 179 pCi/L, respectively. No trends in gross beta results are discernable when compared to previous years sample results.

Although the Lake-out (discharge) sample was not used as an indicator in the Radiological Environmental Monitoring Program, it is monitored for activity. Monthly gross alpha and tritium results from the Palisades Lake-in were used for comparison data against the Lake-out (discharge) sample results. Gross alpha was detected in several Lake-out and Lake-in samples at slightly above minimum detectable activity levels. On six occasions during 2001, tritium activity was detected in the discharge monthly samples. Four of these elevated levels were all correlated to liquid effluent releases and were confirmed by comparison to calculated effluent tritium concentrations. The other two samples were at minimum detection levels.

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.

A total of 36 individual monthly drinking water samples were collected from the three locations in 2001.

Evaluation of the drinking water analytical results was based on a data means comparison between the indicator locations and the control location, as well as a comparison to the Palisades ODCM 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 2.2 pCi/L and 2.0 pCi/L, respectively. Tritium 3

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT was only detected in one control sample at 179 pCi/L in 2001.

D.

Well Water The Palisades site well (1-ST) location is collected daily and composited into a monthly sample. The other eight well locations consist of monthly grab samples.

Well water samples consisting of two one-gallon quantities for each well are sent to Environmental, Inc., Midwest Laboratory for analysis (Ludington control station consists of one one-gallon sample). No treatment of the water samples with a preservative is necessary.

A total of 108 monthly well water samples were collected from nine locations during 2001. Evaluation of the well water analytical results was based on a data means comparison between the six indicator locations (1-ST, 39-ST, 40-ST, 41-ST, 42-ST and 43-ST) and the three control locations (8-SP, 9-TP, and 32-LP), as well as with the Palisades ODCM reporting limits.

Tritium and gross beta analyses were completed for all well water samples. The gross beta means for indicator and control locations were 3.8 pCi/L and 1.7 pCi/L, respectively. No trends in gross beta results are discernable when compared to previous years sample results. Tritium was detected in five indicator samples at a mean value of 266 pCi/L, and two control samples at a mean value of 176 pCi/L.

The site well 1-ST had four out of the five positive results for tritium for indicator stations, with an average of 273 pCi/L. The Lower Limit of Detection (LLD) required for tritium is 500 pCi/L, the action level is 1000 pCi/L, and the reporting level is 20,000 pCi/L. During 2001, three additional well samples were collected directly from well number 17, which supplies the Domestic Storage Tank (well 1-ST). One of these samples showed tritium at 193 pCi/L, which is just above the minimum detectable activity level. During 2002, a Work Order is scheduled to look at the Domestic Storage Tank heat exchanger for a possible tube leak, which could potentially cause cross contamination.

Evaluation of the gross beta activity between indicator and control locations revealed a statistical difference, however, in a comparison between wells used for plant drinking water (1-ST, 40-ST) versus the three control samples, the gross beta results were identical at 1.7 pCi/L.

4

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT The difference between indicator and control stations was caused by the Steam Generator storage facility monitoring wells, which had a gross beta average of 5.5 pCi/L.

E.

Milk Milk samples are required monthly (usually collected the first week of the month) from each designated location. Two one-gallon quantities of raw milk (grab sample) are obtained per sample location in order to meet analytical requirements. Each sample quantity is treated with a sodium bisulfite (40 grams per gallon) preservative prior to being sent to Environmental, Inc., Midwest Laboratory.

A total of 48 individual monthly milk samples were collected from four different dairy farms (stations 26-AK, 27-DH, 28-DC and 29-WS) during 2001. The milk samples are obtained as grab samples from dairy milk holding tanks. No milk analysis identified activity above the minimum detectable level.

F.

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 CaSO4 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.

There were a total of 348 monthly, 116 quarterly, and 29 annual TLDs collected and analyzed during 2001.

The Palisades gamma assessment program consists of twenty-nine locations: one directly on-site, nine near-site and six Steam Generator Storage facility TLDs for a total of sixteen inner ring TLDs; ten outer ring (1.0 to 5.5 miles out); and three control TLDs (30 to 55 miles out). A thirtieth TLD is placed in a lead storage cave and used as a control for in-transit dose monitoring and subtraction.

The monthly and quarterly TLD data evaluations were accomplished by statistically comparing the inner ring TLDs (site boundary locations 1-ST, 13-21 ST and 33-38 ST) and the outer ring TLDs (locations 2-TH through 9-TP, 23-SN25 and 24-SN22) against the control TLD locations (1 0-GR, 1 1-KZ, and 12-DG). The annual TLD data evaluation was done by direct 5

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT comparison of data points only. No monthly or quarterly statistical differences were exceeded.

For 2001, the average gamma readings (mR) were:

Monthly Quarterly Annual Inner ring TLDs (site boundary) 3.9 11.5 41.7 Outer ring TLDs (1.0 to 5.5 miles out) 4.5 13.2 49.1 Control TLD locations 4.2 13.3 48.4 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.

In evaluating the inner ring TLDs to the control TLDs, inner ring 35-ST had the greatest monthly mean value of 4.8 mR, and control station 11-KZ (35 miles east) had the greatest quarterly, and annual mean values of 14.6 mR, and 52.0 mR respectively.

When the same comparison was made for the outer ring TLDs, 2-TH (Tower Hill, 5 miles south) had the greatest monthly, quarterly and annual mean value for any location of 5.4 mR, 16.3 mR, and 58.3 mR, respectively. Overall, the monthly results are trending just slightly higher for indicator and control locations, with a stable trend for the quarterly and annual results.

G.

Crops Food crop samples were 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.

During 2001, sixteen crop samples were collected from two stations (4-JS, and 5-PR). Evaluation of sample analytical results was direct. There was 6

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT no control location used.

Of the radionuclide analyses listed in Table HP 10.4-2, only gross beta analysis resulted in any detectable activity. The gross beta mean value for the indicator locations was 1.73 pCi/g. The crop samples at station 4-JS had the greatest individual mean value for gross beta activity of 2.01 pCi/g. No trends for gross beta results are discernable when compared to previous years sample results.

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.

A total of ten individual sediment samples were collected from five locations during 2001. Eight sediment samples were obtained from Palisades [1-ST discharge, 31-STS (.5 miles south of discharge), 30-STN

(.5 miles north of discharge), and 25-SH (South Haven Beach)] locations and two samples from the Ludington Control Station (32-LP).

Evaluation of the sediment analytical results was based on a data means comparison between Palisades and the Ludington control samples, as well as the Palisades ODCM, Appendix A, reporting limits. Of the radionuclide analyses listed on Table HP 10.4-2, only gross beta, and Cs-1 37 activity were detectable. The gross beta mean values for indicator and control locations were 6.87 pCi/g and 13.51 pCi/g, respectively. The Cs-1 37 mean values for indicator and control locations were 0.010 pCi/L and 0.016 pCi/L, respectively. The gross beta results for the control station in Ludington are trending up slightly the past several years.

I.

Fish Fish samples are collected semi-annually. Samples consist of two species of commercially and/or recreational important species in the vicinity of 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.

A total of eight individual fish samples were collected from two locations 7

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT during 2001. Four indicator samples were obtained from Palisades (1-ST discharge) and four control samples from the Ludington Station (32-LP).

The same species were collected at both 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 Palisades ODCM reporting limits. The gross beta mean values for indicator and control locations were 2.24 pCi/g and 2.26 pCi/g, respectively. Cs-137 was the only gamma emitter detected, with the means identical for indicator and control stations at 0.041 pCi/L. No trends in gross beta or Cs-1 37 are discernable when compared to previous year's sample results.

J.

Broad Leaf Vegetation No broad leaf vegetation samples were collected from the surrounding Palisades environs during 2001. 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. There were no problems associated with the quantity or quality of milk samples for the 2001 reporting year.

K.

Non-Routine Samples No non-routine samples were collected during this reporting period.

L.

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.

As noted in Enclosure A, 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 Palisades Annual Radiological Environmental Operating Report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against 8

PALISADES NUCLEAR PLANT 2001 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT overall environmental trending data. This evaluation is the basis for determining isotopic dispersion and deposition patterns within the surrounding environs of Palisades. All gaseous and liquid effluent results are compared to Palisades ODCM, Appendix A, reporting levels. All isotopic LLDs were met.

IV.

ASSESSMENT OF PALISADES OPERATION ENVIRONMENTAL IMPACT In reviewing the 2001 Palisades radiological environmental monitoring data and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of Palisades 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.

Sample lost in mail (2)

Liquid Plant Radwaste Site Jan, Feb, Apr, July Aug, Sep Oct, Nov No sample There were no liquid effluent batch releases during these time periods. Consequently no sample is collected.

(1) On January 22, 2001, an air meter was found inoperable (not recording) at Station 7-SD.

Power at this station was terminated, and the air meter was returned to station for replacement or repair. During the troubleshooting effort on January 23, 2001, it was determined that the air meter was unable to be repaired, and no spare meter was available. Power was not restored to the station at the end of the troubleshooting sequence. Power was restored at the next sampling date of January 29, 2001. This is a one-time event, no action is deemed necessary to prevent recurrence.

(2) On September 12, 2001, the Iodine cartridge and Particulate filter samples were collected from control station 1 1-KZ and mailed to the local Environmental Inc. vendor. The local vendor then mailed these samples to the Environmental Inc. Laboratory. During this re-packaging evolution, the particulate filter was misplaced and was not forwarded to the Lab. These samples are now forwarded to the Environmental contact at Palisades Nuclear Plant for packaging and shipment.

There has been no recurrence of this event.

2001 LAND USE CENSUS CC Internal Correspondence MLG01 *007 JLFontaine, Palisades REMP/RETS File ERC: LANUSECEN The attached tables and map are the results of the Palisades Land Use Census conducted by MLGrogan and TAVeal on August 22, 2001. Table 10.11-1 references the distance from Palisades to the nearest residence, garden (greater than 500 square feet), beef/dairy cattle, and goat per meteorological sector. Table 10.11-2 identifies the locations of the nearest residence and garden; and of all beef/dairy cattle and goats within a five (5) mile radius of Palisades per meteorological sector. Table 10.11-3 lists the critical receptor locations used in calculation of the offsite doses by the GASPAR computer program.

There were no changes to critical receptor locations from the 2000 Land Use Survey.

Tables 10.11-1 and 10.11-3 are required to 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.

In addition, I requested Air Improvement Resource, Inc. (Dennis Kahlbaum) to run computer code XOQDOQ82, using the 1996 - 2000 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.

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 forceps 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&RSD Radiological Environmental Contact.

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

5.1.3 The C&RSD radiological environmental contact shall conduct periodic (annual) audits of sampling activities.

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 e.

removed, along with any branches extending over the top of the sampler. The goal is to keep every station away from the drip line.

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 5 Page 4 of 15 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT

c.

Audit of collection of other sample media may be performed at the discretion of the C&RSD environmental contact.

d.

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. Replacement air meters are available from Plant C&RSD Environmental contact.

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.

Step Ladder NOTE:

The Control Stations 1 O-GR, 1 1 -KZ, and 1 2-DG are changed out weekly by three 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 ) is completed by the Technician changing out the nine 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.)

c.

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

PALISADES NUCLEAR PLANT Proc No HP 10.10 HEALTH PHYSICS PROCEDURE Revision 5 Page 6 of 1 5 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT

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.

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.

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).

PALISADES NUCLEAR PLANT Proc No HP 10.10 HEALTH PHYSICS PROCEDURE Revision 5 Page 7 of 15 TITLE: PALISADES RADIOLOGICAL ENVIRONMENTAL PROGRAM SAMPLE COLLECTION AND SHIPMENT I.

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.

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

o.

Proceed to the next station. Date and sign the current weeks data sheet upon completion of the entry of all current data.

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.

1.0 INTRODUCTION

The following constitutes the final 2001 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 gamma isotopic analyses, a spectrum is collected covering an energy range from 80 to 2048 KeV.

Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, I-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.

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, 2001 through December, 2001

Appendix 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 (e.g., milk or water) 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.

The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.

Results of crosscheck testing with Teledyne Brown Engineering are also listed.

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 Programn.

Attachment A lists acceptance criteria for "spiked" samples.

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

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 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; xl + s1 and x2 + s2 Reported result:

x L s; where x = (1/2) (xl + x2) and s (1/2) s 2

3.2. Individual results:

<LI,

<L2 Reported result: <L, where L = lower of LI and L2 3.3. Individual results:

x +/- s, <L Reported result:

x k s if x > L; <L 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, x2... Xn are defined as follows:

X=

Ex s=

n Y(x-n- )2 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.
