1 This report provides information relating to radiological environmental monitoring at the Big Rock Point Plant during the period of January through December 1985 as required by Technical Specification 6.9.2.1.

1. RADIOLOGICAL ENVIRONMENTAL MONITORING A. Report Summary Table RSD-E-06A addresses the number of sampling locations, total number of samples collected and the number of locations at which levels were found to be significantly above local concurrent back-ground. A listing of the highest, lowest and annual average cor.cen-tration for the sampling location with the highest average concen-tration is presented in Table RSD-E-06B. Fish, sediment and algae control samples were collected at Ludington (approx. 175 mi. SW of Big Rock) and used in evaluating some of the Big Rock Point biota samples.

B. Environmental Dose Estimates Levels of radioactive materials in environmental media demonstrate that 1% of 10 CFR 20 limits were not exceeded by plant radiological effluents based upon I-131 levels in milk and statistical evaluation of annual TLD stations.

C. Statistical Model Statistical evaluation at the 95% confidence level was performed between the near-site and control locations as described in pro-cedure RSD-E-06. Data evaluation was performed against two cri-teria: the statistical level (the level indicating that nample results obtained from the near sites are greater than those taken from control locations, but the difference is not significant); and the reporting level (minimum detectable difference that exceeds zero at the 95% confidence level).

The reporting level is twice the statistical level. Doses to the public are evaluated if any reporting levels are exceeded.

2. DISCUSSION AND INTERPRETATION OF RESULTS f

A. Air Samples: Comparison of airborne particulate sample results between the near-site and control locations were below the statis-tical level. A total of 364 air samples were collected and analyzed; however 6 samples were deleted from statistical evalua-tion due to low sample yield. The deleted sample results do not indicate any significant reduction in the overall program. The annual gross beta levels were also below the statistical level. All I-131 activity was reported <0.02 pCi/m3 . This is consistent with expected results based on actual plant effluent data.

2 B. Lake Water: Comparison of gross beta and tritium results between the plant intake and discharge were below the statistical level.

. C. Well Water (Drinking Water): Well water samples do not indicate the presence of other than natural background radioactivity. Gross beta comparisons between the site and Charlevoix Municipal wells were below'the statistical level.

D. Milk: Strontium-90 was the only radionuclide detectable in milk samples collected during the reporting period (an absence of short-lived fission products such as I-131 indicates that the origin is not from BRP). Concentrations of Sr-90 are consistent with back-ground from past weapons testing fallout. The Sr-90 statistical level was not exceeded. There were a total of three missing samples from location GS (March, April and May) due to dry cows.

E. Aquatic Biota: Samples of periphyton, algae, crayfish and fish are collected semiannually, when available. The gross beta and Sr-90 fish sample results from Big Rock Point and the Ludington control station were compared. The statistical levels were not exceeded.

All other gamma isotopic results are reported in Table RSD-E-06B.

F. Bottom Sediments: Samples of bottom sediment are collected semi-annually from two locations at Big Rock Point. The gross beta and Sr-90 results from Big Rock Point and the Iudington control station were compared. The statistical levels were not exceeded. All other gamma isotopic results are reported in Table RSD-E-06B.

G. Food Crops (vegetation): Samples of food crops grown in the proxim-ity of Big Rock Point were collected during 1985. The primary areas of collection were the SSE, ESE, SE and E sectors at the 2.0-2.5 mile limit. A total of 7 samples were obtained (2 samples per location per sector - except for the SSE sector, which had I sample collected) for analysis. Sample isotopic results are reported in Table RSD-E-06B.

H. Gamma Dose (TLD): There was 1 monthly (April) TLD reported stolen during 1985 and 1 monthly (January) TLD data result deleted (for statistical purposes) due to suspected improper annealing of the TLD chip. In both cases, the af fected stations are located on-site. No TLD's were reported missing for the near-site or control locations.

Evaluation of the near-site and control TLD data indicated that the statistical level was not exceeded.

Big Rock Point 1985 Land Us.t Census The attachwd tables and map are the results of the Big Rock Point Land Use Survey conducted on June 18, 1985. Table 1 references the distance from Big

Rock Point to the nearest residence, garden, beef / dairy cattle and gbat per meteorological sector. Table 2 identifies the locations of- the nearest residence; of all gardens (greater than 500 square feet) within a three mile radits of plant; and all beef / dairy cattle within a five mile radius of plant.

No goats were located while conducting the 1985 Land Use Survey. An Accompanying map illustrates Table 2.

Prior to conducting the 1985 BRP Land Use Survey, both the Charlevoix County Agricultural Extension Office and the Consumers Power Northern Regional Manager's Office were contacted on June 12, 1985 as specified in Procedure RSD-E-01. There were no significant changes between the 1984 and 1985 Land Use Surveys.

.a Appendix A Interlaboratory Comparison Program Results A-1

Appendix A Interlaboratory Cogarison 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 sagles (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 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 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 environ-mental sample crosscheck program for milk, water, air filters, and food sagles during the period 1980 through June 1985. This program has been conducted by the U. S. Environmental Protection Agency Intercogarison 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 Fif th International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.

Appendix 8 Data Reporting Conventions B-1

Data Reporting. Conventions 1.0. All activities are decay corrected to collection time.

1 -

2.0. Single Measurements .

Each single measurement is reported as follows:

xis where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L .

where L = is the lower limit of detection based on 4.66 uncertainty for a background sample.

3.0. Duolicate Analyses 3.1. Individual results: x1 t s1 x2 2 52 Reported result: xis where x = (1/2) (x1 + x2) s=(1/2)fs2+s2 3.2. Individual results: <L1

<L2 Reported result: <L where L = lower of L1 and L2 3.3. Individual results: xis

<L Recorted result: x i s if x > L;

<L otherwise l

4.0. Comoutation 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 deviations of a set of n numbers x1, x2, . . . xnare defined as follows:

Y=hIx s= L(*'*I2 n-1 4.2 Values below the highest lower limit of detection are not included in the avera58-4.3 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 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 greater than 5, the figure is dropped, and the last retained figure is raised by 1. As an example,11.446 is rounded off to 11.45.

4.5.3. If'the f.igure 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.
