Introduction i

4 j

The 1996 Big Rock Point Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Big Rock Point l

Radiological Environmental Monitoring Program 6s conducted during the 1996 reporting period. Reporting requirements are detailed in Technical j

Specifications 6.9.2.1,13.2 and Tables 13.3-1 through 13.3-3.

i j

There are no remaining 1996 laboratory sample analyses pending

}

completion for inclusion into this report. Detailed sample station j

identification and location information can be found in Attachment 2 of j

Health Physics Procedure HP 10.9 (Enclosure D). The results of all i

environmental samples collected were evaluated as follows:

l 4

l A. Air iodine and particulate, TLDs (monthly and quarterly), and milk data f

were statistically evaluated at the 95% confidence level by th6 i

i methodology detailed in Health Physics Procedure HP 10.2. Tne data i.

was compared against two criteria: the first criterion is the statistical difference which indicates whether the sample results from near sites i

are greater than those from control sites, and whether or not the i

difference is significant. The second criterion is the evaluation level (twice the statistical difference) which is the minimum population mean difference for which the sample mean difference will exceed the statistical difference with 95% confidence. If the evaluation levelis

)

exceeded, then correlation of the results with effluent releases is done.

l B. Well water, lake water intake / discharge, sediment, fish and other aquatic biota s,amples were evaluated using data means comparisons

(

against an appropriate control location (it available) and BRP' Technical Specification limits.

Discussion and Interoretation of Results l

A. Air Samoles l

Comparison of the airborne particulate' sample data between near-site and control locations resulted in no data exceeding the statistical difference level and no data exceeding the statistical evaluation level. In many instances, control location sample values were greater. There was no lodine-131 activity reported above minimum detectable levels.

A tot:1 of 318 Eir s:mplas wire collect:d during 1996. Thrso sampla results were not included in the statistical evaluation due to low sample volumes. Refer to Enclosure A for all sample collection anomaly evaluations. The deleted samples constitute less than 1 % of the total samples. Technical Specification sensitivities were met on all samples other l

i

)

than those already noted.

Comparison of the airborne particulate sample data between near-site and controllocations did not exceed the statistical difference. The j

means of gross beta results for indicator and controllocations were l

]

0.016 pCi/m* and 0.017 pCi/m respectively. No sample analysis 8

identified 1-131 activity above minimum detectati!e levels.

j The air iodine / particulate samples are collected on a weekly basis from j

six air sampling locations. A seventh station, located on the Big Rock Point Plant site, is used for plant trending purposes only and is not part j

j of the Radiological Environmental Monitoring Program. Air is metered through the samplir g units 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.

The 1996 air sample results are consistent with actual effluent releases and site-specific meteorology.

l B. ILDs - Gamma Dose There were a total of 143 monthly,48 quarterly and 12 annual TLDs col!ected for the Radiologica' Environmental Monitoring Program during 1996. Sixty additional on-site TLDs are used for individual reference and are not evaluated as part of the Radiological Environmental Monitoring Program. One monthly TLD was missing from the total (stolen), refer to Enclosure A for all sample anomalies, i

The Big Rock Point gamma assessment program consists of eighteen TLD locations: five on-site TLDs (locations 1-ST,14-G,15-H,17-K,18-L), six inner ring TLDs at the site boundary (locations 9-A,10-B,11-C, 12-D,13 F,16-J), three outer ring TLDs,3 to 4.5 miles out, (locations 2-NM, 3-CH, 4-SL), three control TLDs,10.5 to 50 miles out, (locations l

5-PT, 6-BC, 7-TR), and 1 TLD control placed in a lead storage cave used i

for in-transit dcse measurement.. For 1996 the average monthly gamma readings were: 3.0 mR -for-the inner ring (site boundary) TLDs; 3.0 mR l

for the outer ring (3 to 4.5 miles out) TLDs; and 3.1mR for the control l

TLD locations. The average quarterly gamma readings were: 10.1 mR -

for the inner ring (site boundary) TLDs; 10.6 mR for the outer ring (3 to j

4.5 miles out) TLDs; and 10.9 mR for the control TLD locations. The average of the annual gamma readings were: 42.1 mR for the inner ring; 43.3 mR for the outer ring TLD; and 44.7 mR for the control TLD locations. These results are consistent with historical data. The five I

3 on-site TLD locations sarvs as individual raftrcncss only end are not l

included in this evaluation.

The monthly and quarterly statistical TLD data evaluations were accomplished by comparing the inner ring TLDs and the outer ring TLDs j

against the control TLD locations. The annual TLD data evaluation was done by a direct comparison of data points only.

i in comparing the inner ring TLDs to the control TLDs, station 12-E (0.9 i

mi SSE site boundary) had the greatest monthly mean, quarterly mean, and annual mean. In comparing the outer ring TLDs to the control TLDs, station 4-SL (Susan Lake,3.5 mi SE) had the greatest monthly, mean, l

quarterly mean, and annual mean, j

Background and in-transit gamma exposure levels were accounted for i

and subtracted from the TLD data prior to statistical evaluation. No statistical or evaluating levels were exceeded, and in many instances, i

controllocation TLD data was greater than indicator TLD data. BRP i

Technical specification sensitivities were met.

4 l

Environmental gamma doses are measured monthly, quarterly and 3

annually by placement of three TLD badges per designated location.

Each Teledyne TLD badge contains a 4-zone CaSO phosphor wafer (the 4

wafer also includer an additional backup / reserve read-out zone).

l Sensitivity for the multi-zone TLDs are 1.0 millirem with a linear response of 0.1 millirem to 10D0 rem.

i C. w as i

I A total of 48 individual monthly milk samples were collected from five different dairy farms during 1996. Dairy farms 20-JG, 21-DK and 22-RM or 22-MH serve as indicator locations; and dairy farm 23-BB serves as the controllocation. In October of 1996, the RmCraney Farm (22-RM) sold his remaining dairy herd. Beginning in November 1996, the Merle Hand Farm (22-MH, 2.8 mi ESE) was selected as the replacement milk sample station. No monthly samples were missed during this transition period.

All analysis results listed in Table 10.2-2 were below LLD. No special or supplemental analysis were required,- nor were any Big Rock Technical Specification limits exceeded.

3 Milk samples are required monthly from each designated collection i

location (4 total). A two-gallon quantity of raw milk (grab sample) is i

obtained per collection location in order to meet analytical requirements.

Samples are treated with a sodium bisulfite (40 grams per gallon) preservative prior to being sent to Teledyne Brown Engineering for analysis.

j 4

1 D. Lake Water j-A total of 36 individual monthly lake water composite samples were collected from 3 locations during 1996. Lake water samples from the Lake-in (plant intake) and the Lake-out (plant discharge) are collected daily and composited into monthly samples. Monthly lake water sample composites j

from Ludington are collected as a control sample.

Evaluation of the monthly lake water analytical results was based on a data j

- means comparison between the samples collected from Lake-in and Lake-F out (indicator locations) and the Ludington control location (115 miles SSW i

of the Plant). The lake water results were also evaluated 'against BRP Technical Specification reporting limits.

i Tritium and gross beta analyses are required for all lake watar samples.

One of the twenty-four indicator location lake water samplea had detectable i

tritium levels with a result cf 236 pCi/L. One control lake water sample had l

detectable tritium levels with a result of 163 pCi/L. The means for gross beta indicator and control locations were 2.4 pCi/L and 2.7 pCi/L, l

respectively.

Sr89, Sr90, and gross alpha are required analysis for Lake-out (plant f

discharge). During 1996 gross alpha was detected in one sample, Sr89 was not detected in any sample, and Sr90 was detected in ten of twelve samples with a mean of 0.7 pCi/L. No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during I

1996.

I Ludington lake-in, BRP lake-in and BRP discharge samples are collected j

daily for composite into a monthly sample. A one-gallon quantity of sample i

is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

E. WellWater A total of 24 individual monthly well water samples were collected from the BRP site well (indicator) and the Ludington well (control) during 1996.

~

Tritium and gross beta analyses are required for each monthly sample.

Evaluation of the monthly well water analytical results was based on a data 4

means comparison between the BRP site well and the Ludington well i

samples. No indicator well water samples had any detectable tritium, j

however, two control samples had detectable tritium, with an average of i

167 pCi/L. The gross beta means for the indicator and control location j

were 1.6 pCi/L and 1.3 pCi/L, respectively. No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses j

required during 1996.

A one-gallon grab sample is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

F. Drinkina Water A total of 24 monthly samples were collected from the Charlevoix Municipal Water System (indicator) and the Ludington lake intake (control) during 1996. Tritium and gross beta analyses are required for each monthly sample.

Evaluation of the monthly drinking water analytical results was based on a data means comparison between the Charlevoix Municipal Water System and the Ludington lake samples. Two indicator location tritium results and one control sample tritium result were detectable. The gross beta means for the indicator and control location were 1.7 pCi/L and 2.7 pCi/L, respectively.

No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during 1996.

The drinking water samples are collected daily for composite into a monthly sample at Charlevoix and monthly grab samples are obtained from the Ludington well. A one-gallon quantity of sample is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

G. Crops The collection of food crops / vegetation samples is not required by the BRP Radiological Environmental Monitoring Program Technical Specifications.

There are no regular select locations where food crop samples are collected, however, several crop samples are usually obtained when in season if available. Cabbage leaves, tomato leaves, and beans leaves were collected September 06,1996 from Kuebler Farms (2.5 mi E).

Evaluation of the crop sample analytical results was direct. All data was combined and reported. No controllocation was used.

Only gross beta analyses resulted in any detectable activity. All other results were not detectable. The mean gross beta activity was 4.7 pCi/g in 1996, which is comparable to 5.5 pCi/g in 1995 and 6.1 pCi/g in 1994. No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during 1996.

I i

i 6

i Food crop samples are obtained seasonally, usually from the E, SE, ESE or SSE meteorological sectors and when specifically requested. When 2

i collected, approximately i Kg of sample is placed in a' sealable plastic bag j

' for shipment to Teledyne Brown Engineering. No special treatment of the l

t food crop samples with a preservative is necessary.

H. Sediment A total of 13 individual sediment samples were collected from six locations during 1996. Two sediment samples were obtained each from near the BRP discharge channel (1-ST); from Nine Mile Point (2-NM, 3 mi ENE); from the Ludington control station (26-LP,115 mi SSW); from 1/4 mi south of discharge (24-STS); and from Mt. McSauba (19-MS, 3 mi W); three sediment samples were collected from 1/4 mi north of discharge (25-STN).

1 Evaluation of the sediment aaai/tical results was based on data means comparisons between the BRP samples and the Ludington control samples and the BRP Technical Specification reporting limits. Gross beta, Mn-54, Co-60, and Cs-137 analyses resulted in trace amounts of activity present.

Gross beta was detected in all indicator and co.ntrol samples. Gross beta means for indicators and control stations were 8.3 pCi/g and 8.5 pCl/g, respectively. The Cs-137 was the only gamme emitter detected in control samples (in one of the two samples). Cs-137 mean for indicator and control locations locations was 0.22 pCi/g and 0.026 pCi'g respectively. The Mn-54 mean for the indicator locations was 0.28 pCi/g. The Co-60 mean for the indicator locations was 0.51 pCi/g. These results were consistent with results from 1994 and 1995.

The sediment results from station 25-STN on 10/7/96 showed Co-60 activity at 2.123 pCi/g, which is above the 10 pCi/g Action Level. Elevated Mn-54 and Cs-137 activity was also noted in this sample, however, that activity did not exceed the action level. None of the :+5er Big Rock sediment samples collected on this date showed elevated activities. A subsequant sample obtained at this station on 12/18/96 indicated Co-60, Mn-54, and Cs-137 at normal concentrations. There are no NRC reporting levels for sediment semples.

No other BRP Technical. Specification reporting levels or actic'11evels were exceeded nor were any other special or supplemental analyses required during 1996.

Sediment samples are collected semi-annually from designated locations. A one liter quantity grab sample is usually obtained a few yards off-shore. No treatment of the samples with a preservative is necessary prior to shipment to Teledyne Brown Engineering.

A total of fourteen individual fish samples were collected from four locations during 1996. -Ten samples were obtained from BRP site area: 1-ST 4

discharge,24-STS 1/4 mile south boundary, and 25-STN 1/4 mile north 4

boundary; and four samples from the Ludington control station (26-LP).

l l

l Evaluation of the fish analytical results was based on data means comparisons between the BRP indicator samples and the Ludington control

[

samples 'and the BRP Technical Specification reporting limits. Only gross i

beta and Cs-137 measurements resulted in any detectable activity. The l

gross beta means for the indicator and control locations were 2.5 pCi/g and j.

2.4 pCilg, respectively. The Cs-137 means for the indicator and control j

locations were 0.029 pCi/g and 0.025 pCi/g, respectively. Comparison of results between similar species at the different locations resulted in no l

significant differences.

I j

Two of the fish samples failed to meet the required LLD for Ba-La-140 analysis due to a combination of the small sample collected, and a delay in l

the shipment to the Laboratory. No BRP Technical Specification reporting

[

levels were exceeded, nor were any special analyses required during 1996.

i Fish samples are collected semi-annually.. If possible, at least two different fish species (i.e., forage, sport fish, etc.) are sampled semi-annually at designated sample locations. When caught, a one liter quantity of fish sample is prepared for shipment to Teledyne Brown Engineering. Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation.

J. Cravfish A total of six crayfish samples were collected from three different locations during 1996 ST discharge,24-STS 1/4 mile south boundary, and 25-STN 1/4 mile north boundary. No control samples were taken. Evaluation of the crayfish analytical results was based on a data means comparison with the BRP Technical Specification reporting limits.

Radionuclide analyses results are listed in. Table HP 10.2-2 for crayfish.

There were trace amounts of activity present in most of the samples.

Activity levels were greatest in the samples taken from the discharge area (1-ST) for Co-60, Mn-54 and Cs-137. Activity levels were greatest in the samples taken from the location a quarter mile North of the discharge (24-STN) for gross beta.

Crayfish samples are collected semi-annually at designated locations, i

however, lack of sample media, inclement weather or rough water conditions can either make collecting sufficient sample quantities impossible l.

or wash biota populations out of the immediate sampling vicinity. One liter l

quantities of crayfish are sent to Teledyne Brown Engineering for analysis.

Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation.

K. Aauatic Biota I

j The aquatic biota category consists of algae and periphyton. A total of nine l

discharge, and two from 24-STS 1/4 mile south boundary in 1996. No samples were obtained (not available) from other indicator locations or from j

the Ludington Control Location (26-LP).

i L

Periphyton: Six indicator samples were obtained, two each from BRP (1-ST l

j discharge,24-STS 1/4 mile south boundary and 25-STN 1/4 mile north i

boundary)in 1996.

I l

Evaluation of the biota analytical results was based on a data means j

comparison with the BRP Technical Specification reporting limits.

1 Analyses are listed in Table HP 10.2-2 for algae. There were detectable i

amounts of activity pic.a..t in all of the samples from indicator locations.

i Activity levels were greatest in the sample taken at the discharge 1-ST canal I

for all detectable radionuclides.

greatest in the samples from the discharge canal area for all detected radionuclides, except Cs-137, which was highest at 24-STS,1/4 mi S.

l One of the periphyton samples, and two of the algae samples failed to meet the required LLD for Ba-La-140 analysis due to a combination of a small p

sample collected, and a delay in the shipment to the Laboratory. No BRP Technical Specification reporting levels were exceeded nor were any special i

or supplemental analyses required during 1996. The algae samples taken i

-.--n-.

9 at the BRP discharge had Mn-54 and Co-60 activities in excess of the BRP action level (1 pCl/g). The results (gamma emitters) of this algae sample taken near the BRP discharge canal are lower than the results of 1995 (with the exception of gross beta) and consistent with the results of analysis from previous years. The gross beta results of the discharge algae sample are higher than the previous two years, and comparable to results seen in 1993.

There was only one algae sample obtained from this station in 1996 which contributed to the higher average. There are no NRC reporting levels for algae or periphyton.

Aquatic biota samples (algae and periphyton) are collected semi-annually at designated locations, however, lack of sample media, inclement weather or rough water conditions can either make collecting sufficient sample quantities impossible or wash biota populations out of the immediate sampling vicinity. One liter quantities of biota are sent to Teledyne Brown Engineering for analysis. Each sample is treated with 10 ml of a 10%

formaldehyde solution for preservation.

K. Broad Leaf Veaetation No broad leaf vegetation samples were collected from the surrounding BRP environs during 1996. The colleciion 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. Gaseous and Liauid Radwaste Effluent Comoosite Samoles Although not a direct reporting component in the BRP Annual Radiological Environmental Monitoring Report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. This evaluation is the basis for determining isotopic dispersion and deposition patterns within the surrounding environs of BRP. All isotopic values are compared to BRP Technical Specification reporting levels.

Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Teledyne Brown Engineering for analysis.

The liquid effluent composite sample is based on a specific volume amount of sample collected per total batch volume released. As noted in Enclosure A, for months in which there were no liquid batch effluent releases no sample is sent to Teledyne Brown Engineering. The gaseous radwaste effluent monthly composite sample results are based on analyzing four or five weekly stack gas filters. No special sample treatment with a preservative is required prior to laboratory analysis.

Assessment of Bio Rock Point's Ooerational Environmental imoact in reviewing the 1996 Big Rock Point radiological environmental monitoring i

data and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of Big Rock Point has minimal environmental impact. Most radionuclide activity is at environmental" background" levels. Evidence of an overall environmental isotopic build-up (attributable to Plant effluent) remains negligible as well. In

]

most instances, sample analytical results were below previously established environmental background levels. Station ST-1 is the licensed plant radioactive discharge point and as can be expected, this station is normally the indicator i

location with the highest annual mean when comparing analytical results..

The Ba-La 140 LLD for several aquatic Biota (fish, crayfish, periphyton, and algae) samples were not met in 1996. This LLD was not met for two reasons, one being the small sample size sent to the Laboratory for analysis, and the other was a delay in shipment of the samples to the Laboratory for analysis. Obviously the sample size is dependent upon the number of a particular species collected in the nets, or the amount of periphyton, algae, or crayfish present in the sample location, and is not subject to any corrective actions. In some instances the sample may consist of only a half-liter, which is enough to meet all LLD's with the exception of Ba-La-140.

However, in the future all fish and Biota samples will be shipped to the Laboratory within 7 days to ensure sample delay is not the cause for missing Ba-La-140 LLD's.

A thorough search of the area was conducted, however, missing TLD's were not located and vandalism is suspected. The second quarter and annual TLD's (BRSP -12nd quarter, and BRSP-1 annual) were replaced at this station on June 7,1996 at 15:30.

Thad Popa will evaluate relocating the TLD holder to a less conspicuous area at or near the meteorological tower in order to prevent recurrence.

during the week ending July 18, 1996. Over the duration of this week's sampling, the sample pump vibrated over and crimped the inlet hose restricting 3

{

A review of our monthly TLD Report from Teledyne Isotopes, 1

indicated our onsite TLD readings for stations BRP-#1 (Plant Substation) and BRP-#15 (Vent Shed Area), had increased i

generally by a factor of two.

This increase in dose can be a

accounted for by the resin work being performed on site for j

this time period.

[

TLD station BRP-#15 is within 100 ft. of the transfer l

location for our Spent Resin Tanks.

The increase in general area dose rates for this area caused by the transfer of 4

resin, equipment, and the resin transfer cask itself, i

correlates with the increase in TLD dose for the work period.

l Station BRP-#1, located at the South East corner of our substation, also showed an increase for the same period. plant This location received the shine from the Transfer Casks that were moved and stored at the North side of the Radwaste i

Building in preparation for shipment.

These dose rates should return to normal at the completion of the project in late September or early October.

It should be noted however, that Big Rock maybe unable to ship all the spent resin currently removed.

This may effect station BRP-

1. 1 at the Substation for a longer period.

The long term storage for the two to three resin casks that may not be shipped is behind the Radwaste Building.

Although this is not in direct line with station BRP-#1, a slight increase in background may be visible on this station TLD.

DCC:740/72*10*03/LP The attached tables and map are the ~esults of the Big Rock Point Land r

Use Census conducted by MLGrogan and TRSchlueter on June 28, 1996.

Table 10.11-1 references the distance from Big Rock Point to the l

nearest residence, garden, beef / dairy cattle and goat per meteorological sector within a (5) five mile radius of the plant.

Table 10.11-2 identifies the locations of the nearest residence, of all gardens (greater than 500 square feet) within a three (3) mile radius of the plant, and all beef / dairy animals within a five (5) mile radius of the plant.

Table 10.11-3 lists the critical receptor l

locations used in calculation of offsite doses by the GASPAR computer 4

The only changer from the 1995 Land Use Census are SE sector l

program.

Garden now 1.8 mi (was > 5 mi), and E sector Beef Cattle now 2.7 mi (was 3.0 mi).

There were no changes to any critical Receptor i

r Location.

This land use census is more detailed than required.

Big Rock Point Technical Specification 13.2.3 requires the identification within a i

five miles the location in each of the (9) nine distance of (5) overland meteorological-sectors of the nearest milk animal, the 7

nearest residence and the nearest garden greate.r than 500 square feet i

Air flow meters shall be calibrated annually by General Meter. All c.

in-service air meters will have affixed a valid calibration sticker stating date of calibration, and calibration due date.

d.

Airflow meters should be changed out prior to the expiration of i

calibration dates. Replacement air meters are available from the BRP Radiological Environmental coittact. If an airflow meter is not changed out prior to the calibration expiration date, document the incident on the air sample collection data form.

Interlaboratnry enmnarir.nn Pmeram Resuhn i

Teledyne's Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. Rese programs are operated by agencies which supply environmental type samples (e.g.,

milk or water) containing concentrations of radionuclides know to the issuing agency but not to participant laboratories. He 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 concentration 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.

He results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

his program is conducted by the U.S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, l

Las Vegas, Nevada.

De results in Table A 2 were obtained for hermoluminescent Dosimeters (TLDs), since 1976 via various international Intercomparisons of Envirorunental Dosimeters under the sponsorships listed in Table As2. Also Teledyne testing results are listed.

Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months.

All samples are prepared using NIST tracable sources. Data for previous years available upon request.

Table A 4 lists results of the analyses on in-house " blank" samples for the past twelve months.

Data for previous years available upon request.

Table A-5 list results of the in-house " duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

De results in Table A-6 were obtained through participation in the mixed analyte performance evaluation program.-

he results in Table A-7 were obtained through participation in the Environmental Measurement laboratory Quality Assessment Pt., gram.

Attachment A lists acceptance criteria for " spiked" samples.

Out-of-limit results are explained directly below the result.

4.1 Averages and standard deviatons listed in the tables are computed from all of the

+

{.

individual measurements om thz period averaged; for example, an annual standard i

deviation would not be the average of quarterly standard deviations. The average i 1

and standard deviation (s) of a set of n numbers x1, x2 xn are defined as follows:

F

'I(x - x,)'

s=

-n-1 4.2

- Values below the highest 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 higher.

LLD is reported.

4.4 If all but.one of the values are less than the highest LLD, the single value x s.td associated two sigma error is reported.

L 48 in rounding off, the following rtdes are followed:

4.5.1.

If the figitre 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.

f i

4.5.2.

If the figure following those to be retained is greater than or equal to 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.
