1 A. INTRODUCTION The results of all environmental samples taken during 1985 were statis-tically analyzed *t the 95% confidence level by the method described in Palisades Procedure HP 10.4. The data was evaluated against two cri-teria. The first is the statistical level which indicates that sample results taken from near sites are greater than those taken from control locations, but the difference is not significant. The second is the reporting level (two times the statistical level) which is the minimum detectable difference that exceeds zero at a 95% confidence level. Doses to the public are evaluated if the reporting level is exceeded. Pali-sades was on-line for most of 1985, only coming down November 30th for a refueling outage. All 1985 laboratory analyses were completed for inclusion into this report.
Table 10.4-1 addresses the 1985 Sampling Analysis Summary for Palisades; Table 10.4-2 provides a Sample Data Summary of collected sample results and Table 10.4-3 lists the High, Low and Average Reporting Results for the highest average sampling locations. In addition to the annual Radiological Environmental Operating Report statistical analysis, there are several supplemental attachments provided to further define the Palisades Radiological Environmental Monitoring Program.
B. DISCUSSION AND INTERPRETATION OF RESULTS
- 1. Air Samples Comparison of the airborne particulate sample data between near-site and control locations did not exceed the statistical level. In many instances, control site sample values were greater.
-No I-131 activity was reported above minimum detectable levels.
A total of 624 samples were collected and analyzed; however 20 sample results were deleted from statistical evaluation due to insufficient sample volume flows.
The missing sample results do not indicate any significant reduction in the overall sample program. Technical Specification sensitivi-ties were met.
The results are consistent with actual effluent releases and site-specific meteorology.
- 2. Lake Water Comparison between the plant lake water intake and the South Haven treated drinking water samples showed that statistical levels for gross beta and tritium were not exceeded. The plant lake water outlet samples contained tritium above the statistical limit; however, this is consistent with monthly reported tritium effluent releases. There were no gross beta releases above the administra-tive notification limit of 10 pCi/l from lake-out discharge.
Technical Specification sampling and sensitivity requirements were met.

- 3. Drinking Water See lake water and well water discussion.
- 4. Well Water Comparative data analysis between the site and two off-site well locations showed that the statistical level was not exceeded. The State Park control location has historically had greater gross beta concentrations than either the township park or on-site well loca-tions. A K-40 and Ra 226/228 isotopic study between the Palisades site and State Park wells was initiated in June 1984 to determine.
cause of the higher gross beta concentrations at the State Park.
Results of the study were inconclusive; however sufficient evidence indicates that effluents from Palisades are not a contributing factor to the elevated gross beta concentrations.
The isotopic study was terminated October 1985 after consultation with the NRC. All Technical Specification sampling and sensitivity requirements were met.
- 5. Milk No problems were encountered in obtaining milk samples for 1985.
With the exception of one elevated I-131 result at control station SD, all I-131, Sr-89 and Cs-137 levels were less than detectable.
The one elevated LLD was the result of a laboratory delay in sample counting time. Data comparison of the near site and control loca-tions indicated that Sr-90 levels exceeded the statistical but not the reporting level. Effective September 4, 1985, Constantine Dairy replaced Sherman Dairy as the control location. All Technical Specification sampling and sensitivity requirements were met except as noted.
- 6. Sediment A comparative analysis of sediment data was accomplished by using control samples from the Ludington Pump Storage Facility (located approximately 200 miles North of South Haven) and site samples.
Gross beta results did not exceed the statistical level. In some cases, the control sample gross beta values were greater than the site values. Sr-89 results were at minimum detectable levels' with Sr-90 concentrations only slightly above LLD. Data results of on-site Sr-90 concentrations are approximately 1.5 times less than comparative 1984 values. *Trace amounts of Cs-137 were detected in the on-site sampies. Technical Specification sampling and analysis requirements were met.

- 7. Aquatics - Fish Concentrations of Cs-137, Sr-89 and I-131 were below minimum detectable levels. Gross beta results of on-site fish samples were only slightly above LLD requirements. The Sr-90 levels for both the Ludington control and on-site locations were approximately 2.8 and 2.0 times (respectively) greater than for comparative 1984 values.
The 1985 control location Sr-90 data was 1.5 times greater than the on-site data. Reportable limits for Sr-90 were not exceeded.
Technical Specification sampling and analysis requirements were met.
- 8. Crops Concentrations of Cs-137, Sr-89, and I-131 were below minimum detectable levels. Gross beta results were minimal; being slightly below those of 1984, however Sr-90 levels were elevated approxi-mately 2.0 times from 1984. Reportable limits for Sr-90 were not exceeded. All Technical Specification sampling and analysis require-ments were met.
- 9. Gamma Dose - TLD's There were 14 reported stolen TLD's during 1985 with an additional TLD reader card being damaged at the laboratory (April monthly -
Station 2). Total loss of TLD datum is 15: 8 monthly, 4 quarterly and 3 annual. Evaluation of TLD data was done by comparing all indicator locations to control locations. No monthly, quarterly or annual results exceeded the statistical level. The Palisades gamma dose program consists of 23 locations: 10 directly on-site, 10 off-site (1-6 miles) and 3 control locations (30-55 miles). The on-site locations had an average of 4.8 mR/month; the control locations had an average of 5.3 mR/month; and the near-site (middle perimeter) had an average of 5.4 mR/month. This is consistent with expected results based on effluent releases. Technical Specifi-cation sensitivities were met.
C.
SUMMARY
- 1. No required Technical Specification analyses were missed in 1985.
Twenty of the 624 weekly air samples collected in 1985 were deleted from statistical evaluation because of insufficient sample volume flows.
- 2. A total loss of 15 TLD's is reported for 1985: 14 were stolen from various field locations and 1 TLD reader card damaged at the contrac-tor's laboratory prior to being evaluated. Because of the excessive loss of TLD's during 1985, a security type (tamperproof) of TLD holder will be installed at the theft-prone TLD locations during 1986.

- 3. The K-40 and Ra 226/228 isotopic study between the Palisades on-site and State Park wells was terminated October 1985 after consultation with the NRC. A cause for the higher gross beta concentrations in the State Park well remains unclear; however sufficient evidence indicates that effluents from Palisades are not a contributing factor.
- 4. Constantine Dairy replaced Sherman Dairy as the control milk sample location effectiv~ September 4, 1985. Reasons for the change of location were: 1) Sherman Dairy was in the process of switching to a new milk supplier from the Benton Harbor area, and 2) Sherman Dairy was only providing cream samples for analysis. Milk is preferable for a control sample as it has a higher calcium content than cream. Cream's low calcium content results in a much lower Sr-90 yield than is present in milk.
- 5. The required collection and analyses of principle area crops (blue-berries and apples) were performed as per Technical Specification Table 4.11-1.
- 6. The missing and/or deleted air sample and TLD results did not constitute a significant reduction in the overall program and no special reports per Technical Specification 5.9.3.2 were submitted on 1985 requirements.
D. The 1985 radiological environmental samples were analyzed by Teledyne Isotopes Midwest Laboratory, Northbrook, Illinois.

PALISADES NUCLEAR PLANT 1985 LAND USE CENSUS The attached tables and maps are the result of the Palisades Land Use Survey conducted on July 22, 1985. Table 1 references the distance from Palisades to the nearest residence, garden, dairy cow, beef cattle and goat per meteorolog-ical sector. Table 2 identifies the location of the nearest residence and garden per sector; and all dairy cows, beef cattle and goats within a five-mile radius. The map illustrates the proximity of each item to Pali-sades. Both the Van Buren County Agricultural Extension Office and the CPCo South-western Region Manager's Office were contacted (July 17, 1985) prior to starting the Land Use Survey. The most noticeable change between the 1984 and 1985 Land Use Surveys is the decrease in numbers of dairy cows and beef cattle found within a five-mile radius of Palisades. L IC0486-0098A-HP01

( Appendix A Interlaboratory Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its 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 parti.cipant laboratories. The purpose of such a program is to provide an independent check on the. laboratory's analytical procedures and to alert it to any possible problems.
Participant laboratories measure the concentrations 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 consistentiy 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 environ-mental sample crosscheck program for milk, water, air filters, and food samples during the period 1980 through June 1985. This program has been conducted by the U. S. Environmental Protection Agency Interco111>arison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada. The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976, 1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fifth International Intercomparison of Environmental Dosimeters under the spo~sorships listed in Table A-2.

( 4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from al 1 of the fndividual measurements over the per*iod averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviations of a set of n numbers Xlt xz, *.* xn are defined as follows: x=ltx n s = vi: (x-X)2 n-1 4.2 Values below the hiahest lower limit of detection are not included in the average. - 4.3 If all of the 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 hiahest 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 greater than 5, the figure is dropped, and the last retained figure is r_aised by 1. As ari example, 11.446 is rounded off to 11.45. 4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is increased by one if it is an odd number or it is kept unchanged if an even number. As an example, 11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42. B-3}}
