1986 Big Rock Point Annual Radiological Environmental Operatina Report A. Introduction 4
~
The 1986. Big Rock Point Annual Radiological Environmental Operating Report provides a summary and data interpretation of the-Big Rock Point Radiological Environmental Monitoring Program as conducted during the
- - 1986 reporting period. Reporting requirements are detailed in Technical ~
Specifications 6.9.2.1, 13.2 and Tabler 13.3-1 through 13.3-3. Big Rock Point was online for most of 1986, coming dowa only on February 11-17 and July 1-11 for unscheduled maintenar.cw outages.
There are no remaining 1986 laboratory sample analyses pending (final) completion for inclusion into this report. The results of all environ-
. mental samples collected are evaluated.ns follows:
- 1. Air iodine and particulates, TLD's (monthly and quarterly), and milk data were statistically evaluated at the 95% confidence level (using 1 SAS program) by the methodology detailed in Palisades Procedure HP 10.2. The data was compared against two criterium: the first criteria'is'the statistical level which indicates that sample results from near sites are greater than those from control sites,
- but that the difference is not significant. The second criteria is the reportina level (twice the statistical level) which is the.
. minimum detectable difference that exceeds zero at the 95%-confi-dence level. Doses to the public are evaluated if the reporting level'is exceeded..
[
- 2. Well water, lake water intake / discharge, sediment and biota samples were evaluated using a data means comparison against the appropriate
.. control-location (s) and BRP Technical Specification limits.
- 3. Due to the. affect of the Chernobyl nuclear accident fallout on air, and milk environmental samples, the following samples were deleted
, from statistical evaluations i Air iodine and particulate samples 16 samples - near site locations 5-15_thru 6-5-87 12 samples - control locations 5-15 thru 6-5-87 Milk samples 6 samples - near site locations 5-8 thru 6-12-87 .
- 2 samples - control locations 5-8 thru 6-12-87 In addition to the above, special milk samples were collected and
- analyzed. Further details about the Chernobyl affected environ-mental samples will be addressed under a separate report heading.

l B.* Discussion'and Interpretation of Results 1.- 2 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 location sample values were greater.
With the exception of 28 Chernobyl affected air samples-(all loca-tions) . collected between 5-15-86 and 6-5-86, there was no ~ I-131-activity reported above minimum detectable levels. It should be noted however that control station air samples SPT, 6BC and 7TR had elevated I-131 LLD's of 0.08 pCi/m' due to a laboratory counting delay occurring on 6-25/6-26-86.
\'
A total of 364 weekly air samples were collected and analyzed,
'however 34 sample results were deleted from statistical evaluation as follows:' .-
16 sample results - near site locations: Chernobyl fallout 5-15-86 thru 6-5-86 12' sample results - control locations: Chernobyl fallout 5-15-86 thru 6-5-86 4 sample:results - near site locations: did not meet LLD due to sample collection error and/or. malfunction of equipment. Affected stations were: 2-NM on 7-17-86; ' 3-CH on 7-24-86; l-ST on 11-2 7-86 and 4-SL on 12-11-86.
2 sample results - control locations: did not meet LLD due to '
sample collection error and/or malfunction of equipment. Affected stations were: 6-BC on 4-17-86 and 7-TR on 9-17-86.
- - LThe deleted sample results constitute 9.3% of the collected samples
-not used in the statistical evaluation, however with the exception of the Chernobyl af fected samples (addressed separately), only 1.6%
of the collected samples were unusable for data evaluation. This is l- the same amount of deleted samples as reported in the 1985 Big Rock Point Annual Radiological Environmental Operating Report. The
- - actual missing (unusable) sample results do not. indicate any signifi-l cant reduction in the overall sample program. Technical Specifica-tion sensitivities were met on all samples other than noted.
Air iodine / particulate samples are collected via an approximate i: continuous I cfm air flow through a gelman 47mm air filter (particu-
[ late sample) and Scott air iodine filter cartridge. Both filters are in-line with each other and housed within the same sample holder.
The 1986 air ~ sample results are consistent with actual effluent
! releases and site-specific meteorology.

- 2. TLD's - Camma Dose There was a total _of 216 monthly, 71 quarterly and 17 annual TLD's collected and analyzed. Only 1 quarterly (BRP-05) and 2 annual (BRP-05 and BRP-16) TLD's were lost, however it should be noted that the original December ronthly TLD for location BRP-05 (Petoskey) was discovered missing and replaced with a spare on 12-12-86. The
-location BRP-05 (Petoskey) original monthly, quarterly and annual TLD losses are due to (road side) snow plowing. The TLD's were inadvertently knocked loose and buried in a roadside snow bank.
They could not be found. The BRP-16 (Susan Creek) annual TLD loss was due to an oversight. .The entire TLD packet was removed from it's posting by persons unknown and thrown into the discharge channel (occurred in July). Although the TLD packet was found and re posted by HP Plant personnel, an incomplete TLD accountability was made. Loss of the location BRP-16 annual TLD wasn't discovered until the December (end-of year) pickup.
Because there were no missing monthly TLD's, data for the lost quarterly (BRP-05) and 2 annual (BRP-05 and BRP-16) TLD's could be calculated using monthly TLD data. The calculated data values were entered into the SAS statistical program as standard data points.
The Big Rock Point gamma dose program consists of 18 locations: 11 directly on-site, 3 near-site (ringed 1 to 4.5 miles out); 3 control locations (ringed 10.5 to 50 miles out) and 1 TLD control placed in a lead storage cave. The on-site locations recorded an average of 27.8 mR/ month; the near-site locations (middle TLD ring) recorded an average of 3.9 mR/ month; the control locations (remote / outer TLD ring) recorded an average of 4.0 mR/ month and the lead cave control TLD recorded an average of 2.9 mR/ month. This is consistent with expected results based on actual effluent releases.
The SAS statistical evaluation was accomplished by comparing near-site locations (BRP-02 thru BRP-04) against control locations (BRP-05 thru BRP-07) for both the respective monthly and quarterly TLD reporting periods. The annual TLD data was evaluated by direct comparison of the near-site and control locations on a one-to-one basis (due to small quantity of data used). In all instances (monthly, quarterly and annual comparisons), location 4-SL (Susan Lake - 3.5 mi SE of reactor site) had the greatest mean. Background and intransit gamma exposure levels were accounted for and subtrac-ted f rom the TLD data prior to statistical evaluation. No statisti-cal or reporting levels were exceeded and in many instances, control location TLD data was greater than near-site TLD data. Technical Specification sensitivities were met.
Environmental gamma doses are measured monthly, quarterly and annually by placement of 3 appropriately identified TLD badges per designated location. Each Teledyne TLD badge contains a 4-zone CaSO4 phosphor waffer (the waffer also includes an additional MIO487-0027A-HP01 3 w -

backup / reserve read-out zone). Sensitivity for the multi-zone TLD's are 0.5 millirem with a linear response of 0.1 millirem to.1000 Rem.
3.. Milk i
e A total of' 56 individual monthly milk samples were. collected .from 4-different dairy farms (locations 20-JC, 21-DK, 22-RM and 23-BB).
The milk samples are obtained as grab samples only'(from dairy milk tanks). i i
Due to the effects of the Chernobyl nuclear accident, 8 individual milk samples (6-from near-site locations; 2-from control locations) collected during the months of May and June were deleted from the SAS statistical evaluation (Sr-90 and Cs-137). Trace amounts of I-131 activity was also present in these samples. In addition to ,
the above monthly (routine) samples, 8 special milk samples (2 complete sets - 1 per dairy location) were collected between the dates of.5-9-86 to 5-29-86. For further details, refer to the Chernobyl attachment. With the deletion of the 8 Chernobyl effected milk samples, only 40 samples were statistically evaluated.
Only.the Sr-90 data was statistically evaluated, as all other isotopic results were below LLD. The Sr-90 activity level (LLD is
- 1.0 pCi/L) exceeded the statistical reporting level (twice the
-statistical level) by 0.90 pCi/L.
Further evaluation of the SAS statistical input data provided a correlation coefficient of -0.016 which indicates that the elevated Sr-90 activity levels are not from plant effluents. In addition, other evidence that supports the correlation coefficient value is:
- a. No Sr-89 or I-131 activity (reported less than LLD) was present in either the milk or air filter samples despite effluent ratios of l'0 and 25 times higher (respectively) to Sr-90.
- b. Starting with the 1-1-86 milk sample collections, the J.
Colovich dairy farm (4.5 mi SE) replaced the C. Smith dairy farm (2.3 mi SE) as a near-site milk sampling location. Reason for the change was that Smith went out of business. Comparison of milk Sr-90 data from both dairy locations reveals that the Smith farm has a lower mean Sr-90 value than does the Colovich location. The Colovich data tends to " skew" the SAS statisti-cal evaluation, indicating a false positive result. Prior to 1-1-86, the C. Smith dairy farm had been a milk sampling location since 1979.
Since the elevated Sr-90 activity level in milk is not due to plant related efluent releases, no annual dose assessment to members of the public or special reports is required. With the exception of
, the Chernobyl affected samples, no additional milk samples were t
collected.

Milk samples are required monthly (usually collected by.the 1st Thursday of the month) from each designated. collection location (4
~
. total).. A two gallon quantity of raw milk (grab sample) is obtained per collection location in order to meet analytical requirements.
Samples are treated with a' sodium bisulfite (40 grams -per gallon) preservative prior .co being sent to Teledyne Isotopes for analysis.
- 4. Lake Water A total of 24 individual monthly lake water composite samples were collected from 2 locations during 1986. Lake water intake and discharge samples.are collected daily and composited into monthly samples.
Evaluation of the monthly lake water analytical results was based on
.a data means comparison between intake and discharge samples as well as with the BRP Technical Specification reporting limits. The lake intake serves as a control.
Two of the lake intake composite samples (collected for the months of May and June). were deleted from the data means calculations due to accidental contamination. The May lake intake sample was repor-ted with a gross beta concentration of 42 pCi/L; with the June sample reporting a gross beta concentration of 8.9 pCi/L. Since the.
BRP Technical Specifications require a complete gamma analysis of ,
lake water (whether intake or discharge) when the gross beta exceeds 10 pCi/L (action level), a complete analysis of both composite
. samples was done. Results indicated the following:
May lake intake composite: .
5.7 pCi/L Mn-54 8.2 pCi/L Co-60 52.5 pCi/L Cs-137
<1.8~pci/L Sr-89 0.8 pCi/L - Sr-90 June lake intake composite: 20.6 pCi/L Mn-54 26.7 pCi/L Co-60 8.3 pCi/L' Cs-137 Because of the isotopic types and activity levels present in the two intake composite samples and that none of the other lake intake samples had elevated gross beta and/or isotopic activity present, i
evidence suggests that the samples were collected / processed in contaminated (prior used) containers. As a result of the above, only the analytical mean results of 10 lake intake samples were i compared to the analytical mean results of 12 lake discharge 4
samples. The sample contamination appears to have been an isolated event and is not systematic.

l Tritium and gross beta analyses are required for both the lake intake and discharge monthly samples. For all samples, the analyti-cal results were <500 pCi/L (LLD) for tritium and <4.0 pCi/L (LLD) for gross beta (with the exception of the February and August lake intake; they were 4.9 pCi/L and 4.3 pCi/L, respectively).
The lake discharge monthly composite samples require the additional analyses of gross alpha, Sr-89 and Sr-90. The means of these results were: <l.0 pCi/L for gross alpha, <5.0 pCi/L for Sr-89 and 1.0 pCi/L for Sr-90 per month. No special or supplemental analyses were required for lake discharge during 1986.
Both lake intake and discharge are collected daily for composite into a monthly sample. A one gallon. quantity of sample is sent to Teledyne Isotopes for analysis. No treatment of the water samples with a preservative is necessary.
- 5. Well Water.
A total of 24 individual monthly well water samples were collected from 2 locations during 1986. The Charlevoix Municipal well water is collected daily and composited into a monthly sample, with the on-site well water sample being collected as a monthly grab sample only.
Evaluation of the monthly well water analytical results was based on a data means comparison between the Charlevoix Municipal and on-site samples as well' as with the BRP Technical Specification reporting r
limits. The Charlevoix Municipal well serves as a control.
Tritium and gross beta analyses are required for both the Charlevoix Municipal and on-site well water samples._ For all samples, the analytical results were < 500 pCi/L (LLD) for tritium and < 4.0 pCi/L (LLD) for gross beta. No special or supplemental analyses were necessary during 1986.
A one gallon quantity of sample is sent to Teledyne Isotopes for analysis. No treatment of the water samples with a preservative is necessary.
- 6. Crops The collection of food crops / vegetation samples is not (currently) a scheduled routine within the BRP Radiological Environmental Monitor-ing Program. There are no regular select locations where food crop (in season) samples are collected, however in order to verify stack effluent deposition patterns, several crop samples maybe obtained annually from sectors E, SE, ESE or SSE. For 1936, 2 crop samples were collected at location 23-BB (Bochniak Farm; 11.5 mi E from BRP).
i MIO487-0027A-HP01 6
Evaluation of the cabbage and beet tops from location 23-BB was
. direct. All analytical results were combined and reported. No control location was used.
Of the isotopic analyses listed on Table HP 10.2-2, only the gross beta and Sr-90 analyses resulted in any specific activity. All other analyses were less than LLD. No BRP Technical Specification action or reporting levels were exceeded nor were any special or supplemental analyses required during 1986.
Becuase of current conditions, food crop samples are not routinely collected like other sample media required by the BRP Radiological Environmental Monitoring Program: the samples are obtained seasonally, usually from the E, SE, ESE or SSE meteorological sectors and when.specifichily requested by either the BRP or RSD Radiological Environmental. Coordinator. When collected, approxi-mately 1 Kg of sample is pl' aced in a sealable plastic bag for shipment to Teledyne Isotopes. No speical treatment of the food crop samples with a preservative is necessary.
- 7. Sediment l
A total of 8 individual sedime'nt samples were collected from 3 locations during 1986. Two (2) sediment samples are obtained from BRP (discharge channel and Nine Mile Pointe locations) and two (2) sets of samples from the Ludington control station (South Jetty) semi-annually.-
Evaluation of the sediment analytical results was based on a data means comparison between the BRP and Ludington control samples as
, well as with the BRP Technical Specification reporting limits. The
! individual BRP sample locations were combined into one indicator
! (site) location for comparison purposes; however if any one indi-vidual sample location had a greater specific isotopic annual mean
- than the other location (s.), then that location is identified on
- Table HP 10.2-2.
Of the isotopic analyses listed on Table HP 10.2-2, only Co-60 and other gn=== (non-indicative /non parameter isotopes) were less than
'LLD. All other analyses resulted in trace amounts of activity present. In one instance (gross beta), the Ludington control location even reported greater activity than the BRP (site) loca-tions. No BRP Technical Specification action or reporting levels were exceeded, nor were any special or supplemental analyses re-quired during 1986.
4 Sediment samples are collected semi-annually from each designated location. A one (1) liter quantity grab sample usually obtained a
,few yards off-shore. No treatment of the samples with a preserva-tive is necessary prior to shipment to Teledyne Isotopes.

- 8. Fish A total of 19 individual fish samples were collected from 6 loca-tions during 1986. Fourteen (14) fish samples were obtained from BRP (discharge,1/4 mile South boundary,1/4 mile North boundary, Mt McSauba and Nine Mile Pointe) and five (5) samples from the Luding-ton control station (South Jetty). Fish are collected semi-annually.
Evaluation of the fish analytical results was based on a data means comparison between the BRP and Ludington control samples as well as with the BRP Technical Specification reporting ~1imits. As with the sediment samples, the individual BRP sample locations were combined into one indicator (site) location for comparison purposes; however if any one individual sample location had a greater specific iso-topic annual mean than the other locations, then that location is identified on Table HP 10.2-2.
Of the isotopic analyses listed on Table HP 10.2-2, only Sr-89 and other gamma (non-indicative /non parameter isotopes) were less than LLD.- All other analyses resulted in trace amounts of activity present. The greatest level of Sr-90 activity was found in the Ludington control fish samples. Both the Mt McSauba and 1/4 mile South boundary (BRP) locations had slight Cs-137 activity levels present in salmon samples (both caught on 10-6-86). No BRP Tech-nical Specification action or reporting levels were exceeded, nor were any special or supplemental analyses required during 1986.
As a minimum, at least two (2) different fish species (ie, forage, sport fish, etc) per designated location per year are collected. In most cases however, that criteria is exceeded. When caught, a one (1) Liter quantity of fish sample is prepared for shipment to Teledyne Isotopes. Each sample is treated with 10 ml of a 10%
formaldehyde solution for preservation.
i
- 9. Aquatic Biota l
The aquatic biota category consists of: crayfish, algae and periphy-ton. A total of 19 individual samples were collected from 6 loca -
l tions during 1986. Sample types and locations are as follows:
! Crayfish: 7 samples BRP (1/4 mile South boundary, discharge, 1/4 mile North boundary, Nine Mile Pointe). No samples were collected at Ludington Control.
Algae: 8 samples BRP (Mt. McSauba, 1/4 mile South, discharge, 1/4 mile North, Nine Mile Pointe). Two (2) samples at Ludington Control (South Jetty).
Periphyton: 2 samples BRP (1/4 mile North, discharge). No samples
{
were collected at Ludington Control.

'x Evaluation of the biota analytical results was based on a data means
'~
compariden with the BRP Technical Specification reporting limits; and in the case of the algae samples, an additional comparison was l- made with the Ludington Control Samples. All the individual BRP I
-sample locations were combined into one indicator (site) location l
i for comparison purposes; however if any one individual sample location had a greater specific isotopic annual mean than the other
!J locations, then that location is identified on Table HP 10.2-2.

i Of the isotopic analyses listed on Table HP' 10.2-2, only gross beta and Sr-90 had trace amounts fof activity present in crayfish (Dis-charge location had greatest annual mean for both isotopes) and algae (Ludington control location had greatest annual mean for.both i sotopes). All other isotopic analyses were less than LLD.- l For the periphyton samples; only' the gross beta, Cs-137 and Mn-54, and Co-60 isotopic analyses .had . trace amounts of activity present. : i The discharge location had the greatest annual mean for gross beta, Mn-54 and Co-60; with the 1/4 mile North boundary location having the greatest annual mean for Cs-137. All other isotopic analyses were less than-LLD.
No BRP Technical Specification action or reporting levels were -
exceeded, nor.were any special or supplemental analyses required during 1986.
Aquatic biota samples (crayfish, algae and periphyton) are collected semi-annually at each designated location, however inclement weather i and/or high water conditions can either make collecting sufficient sample quantities impossible or wash biota pcpulations out of the immediate sampling vicinity. This was the situation during 1986.
One (1) Liter quantities of biota are sent to Teledyne Isotopes for analysis. - Esch sample is treated with 10 ml of a 10% formaldehyde
- solution for preservation.

- 10. Broad Leaf Venetation No broad leaf vegetation samples were collected from the surrounding BRP environs during 1986. 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 1986 reporting year.
C. Assessment of Bia Rock Point's Operational Environmental-Impact i In ' reviewing the 1986 Big Rock Point radiological environmental monitor-ing data and comparing it to previous operation and pre-operational data, all. trending parameters indicate that the operation of Big Rock Point has had an insignificant environmental impact.
Since the Chine'se stopped the open atmospheric testing of nuclear devices
- in late 1981-82, environmental background levels of radiation (due to
_ fallout) have shown a continuous decrease. Evidence of an environmental isotopic build-up (attributable to plant effluents) appears negligible as well.
It is unknown at this time what the affect will be (if any) of the Chernobyl fallout on aquatic biota and fish. Immediate affects of the fallout were measured in both air and milk samples for about 6 weeks, MIO487-0027A-HP01 10

May 14, 1986 Edward.L Jordan, Director Division of Emergency Preparedness and Engineering Response Office of Inspection and Enforcement US Nuclear Regulatory Commission Washington, DC 20555 CONSJMERS POWER COMPANY - RESPONSE TO IE INFORMATION NOTICE 86-32, " REQUEST ET)R COLLECTION OF LICENSEE RADI0 ACTIVITY MEASUREMENTS ATTRIBUTED TO THE CHERNOBYL NUCLEAR PLANT ACCIDENT."
This letter is to notify the NRC of Consumers Power Company's intention to report any anomalous environmental radioactivity measurements made at our Palisades and Big Rock Point Plants that can reasonably be assumed to have resulted from the Soviet nuclear power plant (Chernobyl) event. This letter also provides specific data that we obtained from performing measurements of members of a Michigan tour group which visited the region of the Chernobyl Plant shortly after the event occurred. The normal environmental monitoring program (EMP) at our Palisades and Big Rock Point Plants has been augmented, as of May 5 and 8,1986 respectively, to include the collection and analysis of air samples from the immediate plant site. No anomalous results from the normal EMP measurements made at both plants have been noted to date. The augmented air monitoring activities at the Big Rock Point Plant have not indicated any abnormal results and will most likely be terminated at the end of the week of May 12, 1986. The augmented air sampling conducted at the Palisades Plant has, however, yielded increased iodine-131 measurements (I-131 l is not normally detected). While these results are clearly due to the Chernobyl event, the levels are so low as to not cause any health hazard to Plant site employees. This information is presented below in the format j specified by Information Notice 86-32.

This letter is a follow-up response to a previous communication submitted by
. Consumers Power Company to the NRC on 5/14/86 concerning environmental radio-activity measurements taken at Big Rock Point and Palisades Nuclear Plants.
The supplemental environmental radioactivity data provided in this report was obtained by a combination of special request and routine samples collected at Big Rock Point and Palisades in support of the Radioactive Environmental Monitoring Programs (REMP).
Big Rock Point Technical Specification 13.2.1.b and Palisades Technical Specification 4.11.1.b dictate that when the level of radioactivity as the
! resalt of plant effluents in an environmental sampling medium at a specified location exceed the NRC reporting levels (when averaged over any calendar quarter), then a Special Report shall be prepared and submitted to the Commission within thirty (30) days. This report fulfills the Technical Specification requirement, even though the reportable levels of radioactivity are the result of the Chernobyl nuclear accident. Data from this report will be incorporated in the 1986 Annual Radiological Environmental Operating Reports for Big Rock Point and Palisades.
The following analytical results are from air charcoal, air particulate and milk samples:

Table 10.11-1 references the distance from Big Rock Point to the nearest residence, garden, beef / dairy cattle and goat per meteorological sector. Table 10.11-2 identifes the locations of the nearest residence, of all gardens (greater.than 500 square. feet) within a three mile radios of the plant, and all beef / dairy cattle within a five mile radius of the plant. No goats were located while conducting the 1986 Land Use Census. Table 10.11>3 lists the critical receptor locations used in calculation of offsite doses by the GASPAR computer program. An accompanying map illustrates Table 10.11-2.
Prior to conductint the 1986 Big Rock Point Land Use Census, both the Charlevoix County Agricultural Extension Office and Consumers Power Northern Region Office were contacted on June 11, 1986 as specified in Palisades HP Procedure 10.11. There were less gardens and dairy cows observed than in previous years.
