INTRODUCTION The 1996 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 1996 reporting period. Reporting requirements are detailed in Palisades Offsite Dose Calculation Manual (ODCM), Appendix A, sections 111.J and IV.B, Tables E-1 through E-3, and Table F-1.
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 were evaluated in the following manner:
A.
Airborne iodine, airborne particulate and thermoluminescent dosimetry (TLDs) (monthly, quarterly and annual) data was statistically evaluated at the 95% confidence level by the methodology detailed in Health Physics Procedure HP 10.4. 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, an.d 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 the data is correlated with any effluent releases.
B.
..Well water, lake water, sediment, fish and other aquatic biota samples were evaluated using data means comparison against an appropriate control location (if available) and Palisades Offsite Dose Calculation Manual, Appendix A, limits.
II.
REPORTABLE EVENTS No reportable events occurred during this-reporting period.

PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Ill.
DISCUSSION AND INTERPRETATION OF RESULTS A.
Air Sample A total of 627 air samples were collected and analyzed during 1996. One sample result was rejected from the data analysis due to the filter paper being light, most likely the filter was installed off-center. The results were not considered reliable for inclusion in the statistical analysis. Palisades
- oocM, Appendix A, sensitivities were met on all other samples collected.
Refer to Enclosure A for all sample collection anomaly evaluations.
Comparison of the airborne particulate sample data between-near-site indicator locations and control locations did not exceed the statistical*
difference. In most instances, control location sample values were greater than the indicator location samples. The means *of gross beta results for indicator and control locations were 0.022 pCi/m3 and 0.023 pCi/m3, respectively. No 1-131 activity above minimum detectable levels was identified.
Air iodine/particulate samples were 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 through a Gelman 47mm air filter (air particulate) and a Scott air iodine cartridge. Both filters are in-line with each other and housed within the same filter holder.
B.
Lake Water A total of 36 individual monthly lake water composite samples were collected from three locations during 1996. Lake water samples from the indicator locations, Palisades lake-in (1-ST Intake) and South Haven Municipal Water system intake (25-SH Raw water), and the control location, Ludington lake-in (32-LP Intake), were collected daily and composited into monthly samples.
Evaluation of the monthly lake water analytical results was based on a data means comparison between the indicator locations and control location. The results were also evaluated against the Palisades ODCM, Appendix A, reporting limits.
2
PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Gross beta analyses were completed for all lake water samples. The means for gross beta indicators and controls were 2.3 pCi/L and 2. 7 pCi/L, respectively. Tritium was only detected once, in a control sample.
No Palisades ODCM reporting limits were exceeded.
Although the lake-out (discharge) sample was not used as an indicator in the Radiological Environmental Monitoring Program it was monitored for activity. Monthly gross alpha and tritium results from the Palisades lake-in and Ludington intake control samples were used for comparison data against the lake-out (discharge) sample results. Gross alpha was not detected in any lake-out or lake-in samples. Several lake-out tritium results were positive. On five occasions during 1996 the tritium activity for* -
the discharge was above the ODCM action level of 1000 pCi/L. These elevated Jevels were all correlated to liquid effluent discharges and were confirmed by comparison to calculated effluent tritium concentrations.
Palisades lake-in, South Haven Municipal and Ludington lake-i_n water samples were collected daily for composite into a monthly sample. On~
gallon of Palisades lake-in water, and Ludington lake-in water, and two gallons each of South Haven Municipal water were sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with preservative is required.
C.
Drinking water A total of 36 individual monthly drinking water samples were collected from the indicator location, South Haven Municipal Water System (25-SH Raw Water, 25-SH Treated), and the control location, Ludington (32-LP Intake)*, during 1996. The South Haven lake water samples (raw water) were evaluated with lake water and drinking water samples. Samples were collected daily for composite into a monthly sample, for the South Haven raw and treated water samples, and a monthly grab sample was obtained for the Ludington intake sample.
Evaluation of the drihking 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 was required for the treated water only. The gross beta means for the 3
PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERA TING REPORT indicator and control locations were 2.5 pCi/L and 2.7 pCi/L, respectively.
Tritium was only detected once, in a control sample. No special or supplemental analyses were required during 1996.
A two-gallon quantity of South Haven Municipal lake water intake and treated drinking water, and one-gallon of Ludington intake water was sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is required.
D.
Well Water A total of 108 monthly well water samples were collected from nine locations during 1996. Evaluation of the well water ana~ytical results was based on a data means comparison between the six indicator locations (1-ST, 39-ST, 40-ST, 41-ST, 42-ST and 42-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 the well water samples. The gross beta means for indicator and control locations were 4.8 pCi/L and 2.0 pCi/L, respectively. The tritium means for indicator and control locations were 175 pCi/L and 168 pCi/L, respectively.
No Palisades ODCM reporting limits were exceeded for the 1996 well samples. 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 very-consistent at 1.5 pCi/I and 2.0 pCi/I respectively. The Steam Generator and Warehouse monitoring wells (39-ST, 41-ST, 42-ST, and 43-ST), had
- a gross beta average of 6.4 pCi/L for 1996, which caused the statistical difference between indicator and control stations.
In 1996, four samples exceeded the gross beta ODCM action level of 1 O
- pCi/L. Three of these samples were from site well #14 (41-ST), and the
- other was from site well # 15 (42-ST). The range of analytical results for samples exceeding 10 pCi/L was 10.4 to 32.8 pCi/L. The gamma analysis of these samples indicated the presence of K-40 and support the conclusion that these elevated gross beta results were not the result of plant effluents. These wells typically trend around 4 to 8 pCi/L gross beta 4
PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERA TING REPORT and it was not unusual for results to exceed the 10 pCi/L action level during the winter months. Refer to Enclosure A for all sample collection anomaly evaluations.
The Palisades site well (1-ST Well) indicator location was collected daily and composited into a monthly sample. Five other site area wells serve as indicator locations and were sampled once per month. These five were: warehouse building (39-ST), outage building (40-ST), and monitoring wells #14 (41-ST), #15 (42-ST) and #16 (43-ST) which were installed to monitor the groundwater around the Steam Generator Storage Facility. The control locations, State Park (8-SP) and Covert Township Park (9-TP), well water samples were collected as monthly grab samples.
The Ludington location (32-LP Well) serves as an additional control for the well water samples.
Well water samples were sent to Teledyne Brown Engineering for analysis. Each sample consisted of two one-gallon quantities for each well, except the Ludington control location which consisted of a one-gallon sample. No treatment of the water samples with a pres~rvative is necessary.
A total of 48 individual monthly milk samples were collected from four different dairy farms (stations 26-FC/JC, 27-KK, 28-DC and 29-WS) during 1996. The milk samples were obtained as grab samples from dairy milk holding tanks.
No milk analysis identified activity above the minimum detectable level.
No special or supplemental analyses were required, nor were any Palisades ODCM reporting limits exceeded.
Milk samples were collected monthly (usually collected the 1st week of the.
month) from each designated location. Two one-gallon quantities of raw
-- milk (grab sample) were 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 Teledyne Brown Engineering.

TLDs - Gamma Dose There were a total of 347 monthly, 116 quarterly and 29 annual TLDs collected and analyzed during 1996. One Mon_thly TLD was missing (stolen) in 1996. Refer to Enclosure A for all sample collection anomaly evaluations.
The Palisades gamma assessment program consists of 29 indicator locations: one directly on-site, nine near site, and six Steam Generator Storage Facility TLDs for a total otsixteen inner ring TLDs, ten outer ring TLDs (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 (loc~tions 2-TH through 9-TP, 23-SN25 and 24-SN22) against the control TLD locations (10-GR through 12-DG). The annual TLD data evaluation was done by direct comparison of data points only. No monthly or quarterly statistical differences were exceeded.
For 1996, the average gamma readings (mR) were:
Inner ring TLDs (site boundary)
Outer ring TLDs (1.0 to 5.5 miles out)
Control TLD locations Monthly Quarterly. Annual 3.6 11.2 42.7 4.1 12.7 49.8 4.1 12.9 49.7 The one on-site TLD location, 1-ST, serves as an individual reference TLD, however, it was evaluated with the inner ring (site boundary) TLDs.*
in the statistical evaluation..
In evaluating the inner ring TLDs to the control TLDs, control station 11-KZ (35 mi. SSE), had the greatest monthly, quarterly, and annual mean.of 4.8 mR, 14.6 mR, and 56.0 mR respectively:
When* the same comparison was made for the outer ring TLDs, 2-TH (Tower Hill, 5 mi. S), had the greatest monthly, quarterly and annual mean for any location of 5.1 mR, 16.3 mR, and 60.8 mR respectively. In 6
PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT comparison of statistical data, station 2-TH exceeded evaluation levels.
Historically this station exhibits the highest dose rate, even though its not located in the prevailing wind sector.
Environmental gamma doses were measured monthly, quarterly and annually by placement of three TLD badges per designated location.
. Each Teledyne TLD badge contains a 4-zone CaS04 wafer (the wafer also includes an ad.ditional backup/reserve readout zone). Sensitivity for the multi-zone TLDs is 1.0 rnillirem with a linear response of 0.1 millirem to 1000 rem.
G.
Crops During 1996, 10 crop samples were collected from two stations (4-JS, and 5-PR). Evaluation of sample analytical results was direct. There was no control location used.
Food crop samples were collected when available and in season. Two principal area crops, apples and blueberries, were regularly collected as specified in the ODCM. While there are no designated locations where food crops are collected, samples were 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 was placed in a sealable plastic bag for shipment to Teledyne Brown Engineering. No special treatment of the samples with a preservative is necessary.
Of the radionuclide analyses conducted, only gross beta analysis resulted in any detectable activity: The gross beta mean for the indicator locations was 1.60 pCi/g. The crop samples at station 4-JS had the greatest individual mean for gross beta activity of 1.94 pCi/g. No Palisades ODCM action or reporting levels were exceeded, nor were any special or supplemental analyses required during 1996.
7
PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT H.
Sediment A total of 10 individual sediment samples were collected from five locations during 1996. Eight sediment indicator samples were obtained from Palisades (1-ST discharge, 31-STS % mi South of discharge, 30-STN % mi North of discharge and 25-SH South Haven Beach) locations and two control samples were obtained from the Ludington (32-LP).
Evaluation of the sediment analytical results was based on a data means comparison between the Palisades indicator and the Ludington control samples as well as the Palisades Offsite Dose Calculation Manual, Appendix A, reporting limits. Of the radionuclide analyses listed on Table HP 10.4-2, only gross beta, and Cs-137 activity were detectable. The gross beta means for indicator and control locations were 5.7 pCi/g and
- 8.5 pCi/g, respectively. The single positive result for Cs-137 was 0.026 pCi/g at the Ludington control sample, 32-LP. The Ludington control sample, 32-LP,.also had the greatest mean for gross beta. No Palisades ODCM action or reporting levels were exceeded, nor were any special or supplemental analyses required during 1996.
Sediment samples were collected semi-annually from each designated*
location. A one liter quantity grab sample usually is obtained off-shore.
No treatment of the samples with a preservative is necessary prior to shipment to Teledyne Brown Engineering.
I.
Aquatic Biota - Algae The Palisades Radiological Environmental Monitoring Program does not require algae to be collected, although it is collected when it is available.
Two algae samples were collected in 1996 from the Palisades discharge (1-ST) indicator location, however, no samples were available from the Ludington control location, 32-LP.
The 1996 indicator analytical results were lower than 1994 and 1995 indicator activities. The mean gross beta for 1-ST location was 1.9 pCi/g, in comparison to 1994 and 1995 gross beta results of 3.3 pCi/g, and 4:3 pCi/g respectively. Cs-137 and other gamma emitters were not detected in 1996, but were present in indicator samples in the previous two years.
8
PALISADES NUCLEARPLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT One liter quantities of algae (when available) were prepared for shipment to Teledyne Brown Engineering by treating each sample with 10 ml of a 10% formaldehyde solution for preservation.
J-.
F'ish A total of ten individual fish samples were collected from two locations during 1996. Six fish indicator samples were obtained from Palisades, 1-ST discharge, and four control samples from Ludington, 32-LP.
Evaluation of the fish analytical results was based on a data means comparison between the indicator and control samples as well as with the Palisades ODCM reporting limits. The gross beta means for indicator and control locations were 2.2 pCi/g and 2.0 pCi/g, respectively. Cs-137 was detected in three of the six indicator samples, and in all four of the control samples. The Cs-137 mean for indicator and control location were 0.027 pCi/g and 0.025pCi/g respectively. Comparison of results between similar species (trout and sucker) at the different locations resulted in no significant differences. No Palisades ODCM action levels or reporting levels were exceeded nor were any special analyses requested for 1996.
F'ish samples were collected semi-annually. If possible, at least two different fish species (i.e., forage, sport fish, etc.) were sampled semi-annually at designated sample locations. When caught, a one liter quantity of fish sample was prepared for shipment to Teledyne Brown Engineering. Each sample was treated with a 10% formaldehyde solution for preservation.
K.
Broad Lead Vegetation No broad leaf vegetation samples were collected from the surrounding Palisades environs during 1996. 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 1996 reporting year.
L.
Non-Routine Samples No non-routine samples were collected during this reporting period.

PALISADES NUCLEAR PLANT 1996 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT M.
Gaseous and Liquid Radwaste Effluent Composite Samples 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 were evaluated against 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 were compared to Palisades ODCM, Appendix A, reporting levels. All isotopic lower levels of detection (LLDs) were met.
Both t_he gaseous and liquid radwaste effluent composite samples were collected monthly and sent to Teledyne Brown Engineering for analysis.
No special sample treatment with a preservative was required prior to laboratory analysis. The liquid effluent composite sample was based on a specific amount of sample collected per total batch volume release. As noted in Enclosure A, for months in which there were no liquid batch effluent releases no sample was sent to Teledyne Brown Engineering.
The gaseous radwaste effluent weekly composite sample results were based on analyzing weekly stack gas filters.
IV.
ASSESSMENT OF PALISADES OPERATION ENVIRONMENTAL IMPACT In reviewing the 1996 Palisades radiological environmental monitoring data and comparing it to previous operational and pre-operational data, all trending parameters continued to indicate that the operation of Palisades had minimal environmental impact. Most isotopic activity was at environmental background levels. Evidence of an overall environmental isotopic buildup (attributable to Plant effluents) remained negligible as well. In most instances, sample analytical results were below previously established environment background levels.

Liquid Plant Jan-Feb No sample There were no liquid effluent Radwaste Site Mar-May batch releases during these June-Sep time periods. Consequently Oct-Dec No sample is collected and sent to Teledyne Isotopes.
(1)
During 1996, one (1) of the 627 particulate filters collected was light, and the results were not
- included in statistical analysis. This filter was likely installed off-center in the sample head.
Since this only occurred once in 1996 (failure rate of 0.16%), no actions were necessary to prevent recurrence.
(2)
The May monthly TLD at station 11-KZ was stolen. To prevent recurrence, the TLD holder at this station was moved up higher on the telephone pole, out of reach of passersby.
(3)
The Ba-La-140 LLD at the Ludington control station (LP-32) for Brown Trout was not met on a.
sample collected in June of 1996. This LLD was not met for two reasons, one was the small sample size sent to the Laboratory for analysis, and the other was due to the delay in shipment
- to this Lab. Obviously the sample size is dependent upon what's available in the collection nets, and is not subjecf to corrective actions. However, in the future, all fish and Biota samples will be shipped to the Laboratory within seven days of collection.
- Not a required sample location per ODCM Appendix A Table E-1

Internal 1996 LAND USE CENSUS Correspondence cc JRBrunet. Palisades MLG96*028 REMP File DCC:950/72*10*03/LP The attached tables and map are the results of the Palisades Land Use Census conducted by MLGrogan and MLSweet on July 23. 1996. 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.
An accompanying map illustrates Table 10.11-2. Prior to conducting the land use census the Van Buren County Agricultural Extension Office was contacted as required by Procedure HP 10.11.
The only change to critical receptor locations (from the 1995 Land Use Survey) is Beef Cattle. which changed from the SSE sector (3.0 miles). to the NE sector (2.9 miles).
Tables 10.:11-1 and 10.11-3 are required to be updated in the ODCM as Tables 1.4 and l.4a respectively. Attached to this report are the new revisions of Tables 1.4 and l.4a.
