1.0 INTRODUCTION
Because of the many potential pathways of radiation exposure to man from both natural and man-made sources, it is necessary to document levels of radio-activity and the variability of these levels which exist in an area prior to the anticipated release of any additional radioactive nuclides. l To meet this objective, an extensive preoperational environmental radiological monitoring program was initiated for the Toledo Edison Company in the vicinity of the Davis-Besse Nuclear Power Station site. This program included collec-tion (both onsite and offsite) and radiometric analyses of airborne particu-lates, airborne iodine, ambient gamma radiation, milk, groundwater, meat and O wildlife, fruits and vegetables, animal and wildlife feed, soil, surface water, fish, and bottom sediments. Approximately 5 years of preoperational monitoring were completed in April 1977 by the same laboratory that currently operates under the name Teledyne Isotopes Midwest Laboratory (TIML). Fuel elements were loaded in Unit 1 on 23 through 27 April 1977 and the ; initial criticality was achieved on 12 August 1977. Unit 1 achieved one ' hundred percent of its operational capacity on 4 April 1978. Approximately 8-1/2 years of operational monitoring was completed by the end of December I 1985. l This report presents the eighth full year of operational data for the Environ-mental Radiological Monitoring at the Davis-Besse Nuclear Power Station. The program was conducted in accordance with the Davis-Besse Nuclear Power Station Unit No.1 Technical Specifications: Appendix A to License No. NPF-3, Section 3/4.12.1. Appendix A to License No. NPF-3, Section 3/4.12.1 super-ceded Apendix B to License No. NPF-3, Section 3.2 on October 30, 1985. O 3.2-1

- 2. 0 EXECUTIVE SINMARY Operational Nuclear Stations are required by Federal Regulations to submit Annual Operational Reports to the U.S. NRC. The reports must also include the results of the Radiological Environmental Monitoring Program.
This report sumarizes the results of such a program. The program was conduc-ted in accordance with the Davis-Besse Nuclear Power Station Unit No.1 Technical Specifications: Appendix A to Licerde No. NPF-3, Section 3/4.12.1. Appendix A to License No. NPF-3, Section 3/4.12.1 superceded Appendix B to License No. NPF-3, Section 3.2 on October 30, 1985. This program included collection (both onsite and off site) and radiometric analyses of airborne O particulates, airborne iodine, ambient gamma radiation, milk, ground water, meat and wildlife, fruits and vegetables, animal and wildlife feed, soil, surf ace water, fish, and bottom sediments. Results of sample analyses during the period January - December 1985 are summarized in Table 4.5. Tabulations of data for all samples collected during this period, additional statistical analyses of the data, and graphs of data trends are presented in a separate report to the Toledo Edison Company (TIML 1986). Radionuclide concentrations measured at indicator locations were compared with levels measured at control locations and in preoperational studies. The comparisons indicate background-level radioactivities in all sanples collected. No station effect on the environment was indicated in any of the sampling media collected and analyzed. O 3.2-2
O 3.0 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAM 3.1 Methodology The sampling locations for the Environmental Radiological Monitoring Program at the Davis-Besse Nuclear Power Station are shown in Figures 4-1 and 4-2. Table 4.1 describes the locations, lists for each its direction and distance from the station, and indicates which are indi-cator and which are control locations. The sampling program monitors the air, terrestrial, and aquatic environ-O ments. The types of sagles collected at each location and the fre-quency of collections are presented in Table 4.2 using codes defined in Table 4.3. The collections and analyses that comprise the program are described in the following pages. Finally, the execution of the program in the current reporting annual period (January - December 1985) is discussed. 3.1.1 The A;r Program Airborne Particulates The airborne particulate samples are collected on 47m diameter membrane filters of 0.8 micron porosity at a volumetric rate of approximately one cubic foot per minute. The filters are collected weekly from eleven locations (T-1. T-2, T-3, T-4, T-7, T-8, T-9, T-11, T-12 T-23, and T-27), placed in individual glassine protective envelopes, and dispatched by mail to TIML for radiometric analyses. The filters are stored at least five days af ter collection to allow for decay of' naturally-occurring short-lived radionuclides and then analyzed for gross beta activ-ity. The quarterly composites of all air particulate sagles from indicator locations (T-1, T-2, T-3, T-4, T-7, and T-8) and of all air particulate samples from control locations (T-9, T-11. T-12 T-23, and T-27) are gama scanned and analyzed for strontium-89 O and -90. 3.2-3
O v Airborne Iodine Each air sampler is equipped with a charcoal trap in-line af ter the filter holder. The charcoal trap at each location is changed _ at the same time as the particulate filter and analyzed f or iodine-131 immediately after arrival at the laboratory. Ambient Gamma Radiation The integrated gamma-ray background from natural radiation is measured with thermoluminescent dosimeters (TLD) . Monthly and quarterly TLDs are placed at thirteen (13) original locations (the eleven air sampling locations and locations T-5 and T-24). On 1 January 1980 eighteen (18) new TLD sangling locations were added to the program. Twelve locations (T T-49) were established at the site boundary ranging in distance from 0.5 mi to 1.2 mi from the stack. Six locations were established at a distance of 3.7 mi to 5.0 mi from the stack. Since about 50% of the outer 5 mi ring is over Lake Erie, only six additional locations were required to cover all sectors on the land. Each shipment of TLDs includes in-transit TL0s which are stored in a shield at the station and returned with the field TLDs af ter their removal. In-transit exposures are measured by the in-transit TL0s and subtracted from the field TLD measurements to obtain their net exposure. 3.1.2 The Terrestrial Program Milk Two-gallon milk samples are collected twice a month during the grazing period (May through October) and monthly during the rest of the year from two indicator locations (T-8 and T-20) and one control location (T-24). The milk samples are analyzed for iodine-131, strontium-89 and -90, calcium, stable potassium, and are gamma scanned. Groundwater One-gallon well water samples are collected quarterly from two indicator locations (T-7 and T-17) and from one control location (T-27). The gross beta activity is determined on the suspended and dissolved solids of each sample. The samples from control location (T-27) and composites f*om indicator locations (T-7 and (' x T-17) are also ganrna scanned and analyzed for strontium-89 and
-90, and tritium.
3.2-4
O Edible Meat Semi-annually, domestic meat samples (chickens) are collected from one indicator location (T-32) and one control location (T-34) and one representative species of wildlife (muskrat or . raccoon) is collected onsite (T-31). In addition, one Canada i goose and one snapping turtle are collected annually onsite (T-31) or in the site vicinity (T-33). Gamma spectroscopic analysis is performed on the edible portions of each sample. Fruits and Vegetables Semiannually, at least two varieties of. fruits and vegetables are collected from each of the two indicator locations (T-8 and T-25) and from one control location (T-34). The edible portions are gamma scanned and analyzed for strontium-89 and -90. Green Leafy Vegetables Monthly, during the harvest season, green leafy vegetables are collected from one indicator location (T-36) and one control location (T-37). The samples are analyzed for iodine-131. O Should green leafy vegetables from private gardens be unavail-able, nonedible plants with similar leaf characteristics from the same vicinity may be substituted. Animal-Wildlife Feed Animal feed is collected semi-annually fro.n one indicator location (T-8) and one control location (T-34). Cattlefeed is collected during the first quarter and grass is collected during the third quarter. Also, once a year, a sample of smartweed is collected from location T-31 (onsite). Gamma'spgetroscopic analysis is performed on all sanples. % N . N, s Soil , Once a year, soil samples are.. collected f rom'all el50eo air s sampling locations; six indicator' locations (T21, T-2, T-3,'T-4, T-7, and T-8) and five contrgillocations (T-9, T-11, T-12, T-23, and T-27). Gamma spectroscopic analysis ist performed on'.all samples.

3.1.3 The Aquatic Program Treated Surface Water Weekly grab samples of treated water are collected at one indi-cator location (T-28, Unit 1 treated water supply, onsite) l and two control locations (T-11 and T-12, Port Clinton and Toledo l filtration plants). The samples from each location are com-posited monthly and analyzed for gross beta activity in dissolved and suspended solids. Quarterly composites from indicator and combined control locations are gamma scanned and analyzed for strontium-89 and -90. Quarterly composites from each location are analyzed for tritium. Untreated Surface Water Weekly grab samples of untreated water from Lake Erie are col-lected from one indicator location (T-3) and one control location (T-11), and weekly composite samples are collected from the second control location (T-12). Samples at Locations T-11 and T-12 are collected from untreated water taps at Port Clinton and Toledo filtration plants, respectively. In addition, monthly composite samples are collected from cne in-plant water supply (T-28, Unit 1 O untreated water supply, onsite). The samples from each location are composited monthly and analyzed for gross beta activity in dissolved and suspended solids. Quarterly composites from com-bined indicator and combined control locations are gamma scanned and analyzed for strontium-89 and -90. Quarterly composites from one control location (T-11) and two indicator locations (T-3 and T-28) are analyzed for tritium. Beginning in June 1984, the frequency of analysis for tritium and gamma-emitting isotopes on samples from Location T-12 was changed from quarterly to monthly. Also, beginning in June 1984, weekly composite samples were collected from an additional location (T-50), composited monthly, and analyzed for tritium and gamma-emitting isotopes. Fish Two species of fish are collected semi-annually from each of two locations in Lake Erie; from one indicator location in the vicinity of the discharge (T-33) and one control location greater than 10 miles from the plant (T-35). The flesh is separated from the bones and analyzed for gross beta and gamma-emitting isotopes. 3.2-6 l .
Bottom Sediments Semi-annually, bottom sediments are collected from three loca-tions in Lake Erie; at two indicator locations, intake (T-29) and discharge (T-30), and at one control location about 5.3 I miles WNW from the plant (T-27). The samples are gamma scanned and analyzed for gross beta and strontium-89 and -90. 3.1.4 Program Execution . Program execution is summarized in Table 4.4. The program was executed as described in the proceding sections with the follow-ing exceptions:
- 1. There were no gross beta in air particulates nor airborne iodine-131 data from Location T-4 for the periods ending 11-25-85 and 12-02-85 because a calibr~ted a pump was not available.
- 2. There were no gross beta in air particulate nor airborne iodine-131 data from Location T-9 for the collection period ending 12-02-85 because a calibrated pump was not available.
- 3. There were no gross beta nor airborne iodine-131 data from Location T-23 for the period ending 07-15-85 because of a pump malfunction.
4 There were no TLD data for Location T-49 for the month of October,1985 because TLDs were lost in the field due to vandalism.
- 5. Untreated surf ace water from Lake Erie at sita boundary (T-3) was not collected during the month of February of 1985 because the lake was frozen.
3.1.5 Census of Milch Animals In compliance with Appendix B, Section 3.2 of the Technical Specifications for the Davis-Besse Nuclear Power Station, the annual census of milch animals was conducted on May 22, ?3, and 28, 1985 by Environmental Monitoring Group personnel, Davis-Besse Nuclear Power Station.

t O 3.2.1 Atmospheric Nuclear Detonations There were no reported atmospheric nuclear tests in 1985. The last reported test was conducted by the People's Republic.of China on 16 October 1980. The reported yield was in the 200 3 kiloton to 1 megaton range. 1 3.2.2 The Air Environment Airborne Particulates Gross beta measurements yielded annual means that were nearly identical at the five control locations and the six indicator locations (0.024 pCi/m3 and 0.022 respectively). The highest annual mean (0.027 pCi/m3) pCi/m3, was measured at the control location (T-23). i A spring peak in beta concentration had been observed almost annually for many years (Wilson et al., 1969). It had been attributed to f allout of nuclides from the stratosphere (Gold et al., 1964). It was pronounced in 1981 and occured to a lesser degree in 1982. However, the ,neak did not occur in 1983, 1984, or 1985. This was similar to the years 1976 and 1979. Strontium-89 and strontium-90 concentrations were below their respective LLDs of 0.005 and 0.001 pCi/m3 in all samples. Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. The only gamma-emitting isotope detected was beryllium-7 which is produced continously in the upper atmosphere by cosmic radiation ( Arnold and Al-Salih, 1955). There was no indication of a station effect on the data. Airborne lodine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 in all samples with the following exceptions due to low volume resulting from power loss or pump malfunction: T-9 on 11-04-85 (<0.58); T-9 on 11-11-85 (<0.15); T-12 on 10-07-85 (<0.23); T-23 on 02-25-85 (<0.16); T-23 on 12-09-85 (<0.17); and T-23 on 12-23-85 (<0.14). 3.2-9

Ambient Gamma Radiation At thirteen (13) regular locations the monthly TLDs measured a mean equivalent dose of 12.8 mR/91 days at the indicator locations and a mean of 14.4 mR/91 days at control locations. These results were in agreement -with the values obtained by quarterly TLDs and were similar to the levels observed in 1984 (11.6 mR/91 days and 13.0 mR/91 days, respectively). The highest annual means for monthly TLDs (18.8 mR/91 days) and for quarterly TLDs (19.6 mR/91 days) occured at indicator location T-8. At twelve special locations established at the site boundary, the mean equivalents were essentially identical to those measured at the regular indicator locations (13.8 mR/91 days and 14.1 1 mR/91 days, monthly and quarterly, respectively). Higher gama radiation levels measured at locations away from l the lake were also observed in previous years and are attributed to the higher potassium-40 content in the soil.
^ The annual mean dose equivalent for all locations measured by ; monthly and quarterly TL0s was 14.4 mR/91 days and was similar to that measured in 1980 (14.5 mR/91 days),1981 (14.8 mR/91 days),1982 (14.5 mR/91 days),1983 (13.2 mR/91 days), and 1984 (13.2 mR/91 days). This is lower than the estimated average natural background radiation for Middle America,19.5 mrad / quarter which is based on data on Pages 71 and 108 of the report " Natural Background Radiation in the United States" (National Council on Radiation Protection and Measurements, 1975). The terrestrial absorbed dose (uncorrected for structural and body shielding) ranges f rom 35 to 75 mrad / year and averages 46 mrad / year for Middle America. Cosmic radiation and cosmogenic radionuclides contribute 32 mrad / year for an average of 78 mrad / year or 19.5 mrad / quarter.
3.2.3 The Terrestrial Environment Milk i A total of 54 analyses for iodine-131 in milk were performed
- during the reporting period. All samples contained less than 0.5 pCi/l of iodine-131. l Strontium-89 was below the LLD levei of 2.0 pCi/l in all samples.

lO Strontium-90 activity was detected in all samples collected and ranged f rom 0.7 to 2.8 pCi/1. The annual mean value for strontium-90 was slightly lower at the indicator locations than at ' the control locations (1.3 and 1.6 pCi/1, respectively). The location with the highest mean (1.6 pCi/l) was control -location T-24. The mean values were similar to those measured in 1977 } through 1984.

The concentrations of barium-140 and cesium-137 were below their ' respective LLDs in all sagles collected. f ] 1 Results for potassium-40 were similar at control and indicator locations (1270 and 1320 pCi/1, respectively). Indicator location T-20 had the highest mean (1350 pCi/1). \ Since the chemistries of calcium and strontium, and potassium.
! and cesium are similar, organisms tend to deposit ' cesium-137 in muscle tissue and strontium-89 and -90 in bones. In order to i detect potential environmental accumulation of these radio-nuclides, the ratios of the strontium-90 activity to the weight of calcium and of the cesium-137 activity to weight of stable l potassium were monitored in milk. The measured concentrations of calcium and stable potassium were in agreement with previously l
determined values of 1.1610.08 g/l and 1.50f0.21 g/1, respectively
~
(National Center for Radiological Health,1968). No statistically significant variations in the ratios were observed. j Groundwater (Well Water)
' Gross beta concentrations in suspended solids were below the LLD of 1.3 pCi/1 in all samples but one. The detected concentration ! was barely above the LLD level (1.4 pCi/1). Gross beta concentra- l l
{ tions in dissolved solids averaged 3.2 pCi/1 at the indicator l locations and 2.8 pCi/l at the control location. The location with the highest annual mean was the indicator location T-17 and l averaged 3.3 pCi/1. The range of gross beta concentrations were j similar to those observed in 1978 through 1984. 4 I
! Tritium concentration was below the LLD of 330 pCi/1 in all sag les.
i Strontium-89 and strontium-90 concentrations were below their respective LLDs of 2.0 pCi/l and 1.0 pCi/1 in all samples. } l 3.2-11
f% , V All samples were below the LLD of 10.0 pCi/l for cesium-137 concentration. The activities detected in well water were not significant when _ compared with the LLDs and were not attributable to the station operation. Edible Meat In the edible meat samples (chickens, muskrat, Canada goose, and snapping turtle) the mean potassium-40 concentration was 2.69 pCi/g wet weight for the indicator locations and 2.33 pCi/g wet weight for the control location. Cesium-137 concentration was below the LLD of 0.062 pCi/g wet weight in all samples. 1 Fruits and Vegetables Strontium-89 was below the LLD of 0.067 oCi/g wet weight in all samples. Strontium-90 was detected in eleven of sixteen samples and ranged from 0.002 to 0.032 pCi/g wet weight. The only gamma-emitting isotope detected was naturally-occurring potassium-40. The mean concentrations were 2.51 pCi/g wet weight for the indicator locations and 1.72 pCi/g wet weight for the control locations. The concentrations detected were identical or i similar to those detected in 1977 through 1984. All other gamma- l emitting isotopes were below their respective LLDs. . 1 1 Green Leafy Vegetables Green leafy vegetables (cabbage) collected during harvest season ! were analyzed for iodine-131. All results were below the LLD of 0.039 pCi/g wet weight. All gamma-emitting isotopes except potassium-40 were below their respective LLDs. Potassium-40 concentration averaged 3.85 pCi/g wet weight and 2.07 pCi/g wet weight for indicator and control locations, respectively. No station effect was indicated. Animal-Wildlife Feed In grass, smartweed, and corn the only gama-emitting isotope detected was potassium-40. The annual mean K-40 concentration for the control location T-34 was 3.69 pCi/g wet weight compared to m the mean value of 4.37 pCi/g wet weight for indicator locations. All other gamma-emitting isotopes were below their respective LLDs. 3.2-12
i lO i Soil l i Soil samples were collected in June and November 1985 and ana-i lyzed for gamma-emitting isotopes. The predominant activity was potassium-40 which had a mean value of 15.1 pCi/g dry weight at-the indicator locations and 15.9 pCi/g dry weight at the control :
- locations. Cesium-137 concentration was above the . LLD of 0.12 pCi/g in. seven of the eleven samples. The mean concentration at the indicator locations were 0.31 pCi/g dry weight and 0.72 pCi/g
- dry weight at the control locations. The highest cesium-137
- concentration, 1.29 pCi/g, was detected at the control location ;
T-9, 6.8 miles SW of station. The level of concentrations and l i distribution pattern was very similar to those observed in 1978 4 through 1984. 3.2.4 The Aquatic Environment , 4 Water Samples - Treated i l In treated water samples the gross beta activity in suspended j solids was below the LLD of 0.9 pCi/1 in all samples. The mean i gross beta concentration in dissolved solids was identical ! at indicator and control locations (2.2 pCi/1). The values are
- similar to those measured in 1975 through 1984. Tritium activity was below the LLD of 330 pCi/1 in all sanples.
j Strontium-89 and strontium-90 concentrations were below the LLD levels of 1.4 pCi/1 and 0.9 pCi/1, respectively, in all samples. Cesium-137 level was below the LLD of 10 pCi/1 in all samples. Similar results were obtained in 1979 through 1984. t Water Samples - Untreated ,
- In untreated water samples, ' the mean gross beta concentration in suspended solids averaged 2.1 pCi/l at - indicator locations and j 1.1 pCi/l at control locations. In dissolved solids the mean concentration was identical at -both indicator and control loca- I tions (3.0 pCi/1). For total residue, the mean concentrations 4 were 3.4 pCi/1 at indicator locations and .3.1 pCi/1 at control locations. None of these results show statistically significant differences between indicator and control locations.
1 The tritium concentration was below LLD of 330 pCi/1 in all but ! one sample. The detected concentration of. 360 pCi/l was barely above the LLD level and statistically is not significant.

l Strontium-89 concentration was below the LLD of 2.0 pCi/l in all samples. Strontium-90 was detected in four of eight samples and the concentration was near the LLD level of 0.8 pCi/l ranging from 0.8 to 1.0 pCi/1. Cesium-137 concentration was below the LLD of 10.0 pCi/l for all locations. No plant effect was indicated. Fish The mean gross beta concentration in fish muscle was similar for l indicator and control locations (2.57 and 2.82 pCi/g wet weight, respectively). The predominant gamma-emitting isotope detected was naturally-occurring potassium-40. The mean potassium-40 concentration was i 2.82 pCi/g wet weight for the indicator location and 3.07 pCi/g wet weight for the control location. Cesium-137 concentration was i below the LLD level of 0.022 pCi/g wet weight in all samp?es but one. The detected concentration was 0.027 pCi/g wet weight, barely above the detection limit. The levels of concentra-tions were similar to those observed in 1978 through 1984. O No plant effect was indicated. Bottom Sediments , The mean gross beta concentration in bottom sediments was 30.5 pCi/g dry weight for indf cator locations and 16.6 pCi/g dry weight for the control location. The location with the highest mean was indicator Location T-30 (31.8 pCi/g dry weight). Indicator Location T-29 had the highest mean potassium-40 concentration l (17.0 pCi/g dry weight) which was the major contributor to the i gross beta activity at all locations. Concentrations of strontium-89 and strontium-90 were below the LLD levels of 0.038 and 0.009 pCi/g dry weight, respectively, in all samples. Cesium-137 concentration was not detected in any of the six samples above the LLD level of 0.054 pCi/g dry weight. Similar I levels, distribution, and composition of detected radionuclides l were detected in 1978 through 1984. O 3.2-14 , 1
O U 3.2.5 Summary and Conclusions Results of sigle analyses during the period January - December 1985 are sumarized in Table 4.5. Tabulations of data for all l samples collected during this period, additional statistical 4 analyses of the data, and graphs of data trends are presented in j a separate report to the Toledo Edison Company (TIML 1986). Radionuclide concentrations measured at indicator locations were compared with Irvels measured at control locations and in pre-operational stuaies. The comparisons indicate background-level radioactivities in all samples collected. No station effect on the environment was indicated in any of the sampling media collected and analyzed. 1 I 1 l O 3.2-15

V Aopendix A Interlaboratory Comparison Prooram 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 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 partic.ipant 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-O mental sample crosscheck program for milk, water, air filters, and food samples during the period 1982 through October 1985. This program has been conducted by the U. S. Environmental Protection Agency Intercomparison 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.

1985 LAND-USE AND MILK ANIMAL CENSUS O)
\
v Background and Methods Appendix I, to 10 CFR 50, states "The licensee shall establish an appropri-ate surveillance and monitoring program for evaluating doses to individu-als from principal pathways of exposure." Appendix B, Section 3.2, to the , Davis-Besse Technical Specifications states "an annual census of animals l producing milk for human consumption shall be conducted at the start of ' the grazing season to determine their location and number with respect to the site." Pathways are defined as any means by which radionuclides can i get into the human food chain. Pathways recorded in the Land-Use and Milk Animal Census are residences, vegetable gardens, milk animals, and beef i animals. All the pathway locations must be determined within a five-mile radius of the station vent. All dairy goats within a fifteen-mile radius of the station vent must also be located. The 1985 Land-Use and Milk Animal Census was done on May 22, 23 and 28, 1985. Local agencies, such as the Northwest Ohio Goat Dairyman Associa-tion, and the Ottawa County, Sandusky County, ana Lucas County Cooperative Extension Agencies provided information on dairy goat owners in their areas. l The Ottawa County Cooperative Extension Agency confirmed the presence of ! all beef cattle, milk cows, and milk goats reported within the five-mile radius of the station. The pathway distances listed below are measured l i (Q v j from the station vent. i I The following changes were recorded in the 1985 census: l N Sector - A vegetable garden pathway at 890 meters which was present l last year was not observed at the time of the census. ; Since no major change had occurred in the area and the l census was taken in early spring, it was assumed that the garden would be planted at a later date and was included in the census. NNE Sector - The vegetable garden pathway at 900 meters which was ! present last year was not observed at the time of the l census. For the same reason as stated above, it was included in the census. ESE Sector - A dairy goat pathway was added at 21,240 meters (13.2 miles). SE Sector - A dairy goat pathway at 18,170 meters (11.3 miles) was deleted since it did not appear on the 1985 dairy goat listing. SSE Sector - The vegetable garden pathway at 2,230 meters was changed to 2,680 meters. A new dairy goat pathway was also added at 23,500 meters (14.6 miles).
,O U
1
SSW Sector - The vegetable garden pathway was changed from 1,000 meters to 1,260 meters. SW Sector - The vegetable garden pathway at 990 meters was changed to
- 1,050 meters. New beef cattle were added to the sector, i changing the beef cattle pathway from 5,050 meters to
! 4,740 meters. WSW Sector - The vegetable garden pathway was changed from 2,590 meters to 1,640 meters. The beef cattle pathway changed from 8,560 meters to 8,100 meters. The dairy goat pathway also changed from 11,100 meters to 14,480 meters i (9.0 miles). This change occurred since a dairy goat at 11,100 meters did not appear in the 1985 dairy goat list. W Sector - The dairy goat pathway at 4,140 meters was eliminated
! since it did not appear on the 1985 dairy goat list.
t l WNW Sector - The vegetable garden pathway was changed from 1,730 meters to 2,880 meters. , NNW Sector - The vegetable garden pathway at 1,250 meters was changed to 1,330 meters. Results ] [ ss The results of the 1985 Land-Use and Milk Animal Census are presented in short form in Table 1. The detailed receptor list in Table 2 is used to
)
)
update the data file of the Semiannual Radioactive Effluent Release 1 Report. Table 7 is the updated table for Appendix B of the Offsite Dose Calculation Manual (0DCM). The ODCM describes the methodology and ., parameters used in calculating offsite doses due to radioactive liquid and gaseous effluents and in calculating liquid and gaseous effluent j monitoring instrumentation alarm / trip setpoints. The critical receptor
! of the 1985 Census has not changed from the 1983 and 1984 reports. The ; vegetable pathway at 900 meters in the NNE sector with X/Qr value of 1.27 E-6 i and D/Q value of 1.39 E-8 is still the most critical receptor.
