EXECUTIVE

SUMMARY

This Annual Monitoring Report for the period of January 1 through December 31, 2006 is submitted in accordance with Point Beach Nuclear Plant (PBNP) Units 1 and 2 Technical Specification 5.6.2 and submitted under Dockets 50-266, 50-301 and 72-005 for Facility Operating Licenses DPR-24 and DPR-27 respectively. The report presents the results of effluent and environmental monitoring programs, solid waste shipments, non-radioactive chemical releases, and circulating water system operation.

During 2006, the following Curies (Ci) of radioactive material were released via the liquid and atmospheric pathways:

Liquid Atmospheric Tritium (Ci) 607 74.5 1

Particulate (Ci) 0.034 0.00000075 Noble Gas (Ci) (-1 4.330

(-)Noble gases in the liquids are added to the atmospheric release totals.

1 Atmospheric particulate includes radioiodines, but not F-18, in this table.

For the purpose of compliance with the effluent design objectives of Appendix I to 10 CFR 50, doses from effluents are calculated for the hypothetical maximally exposed individual (MEI) for each age group and compared to the Appendix I objectives. Doses less than or equal to the Appendix I values are considered to be evidence that PBNP releases are as low as reasonably achievable (ALARA). The maximum annual calculated doses in millirem (mrem) or millirad (mrad) are shown below and compared to the corresponding design objectives of 10 CFR 50, Appendix I.

LIQUID RELEASES Dose Cateqorv Calculated Dose Ap~endixI Dose Whole body dose 0.0056 mrem 6 mrem Organ dose 0.0057 mrem 20 mrem ATMOSPHERIC RELEASES Dose Cateqow Calculated Dose Appendix I Dose Organ dose 0.029 mrem 30 mrem Noble gas beta air dose 0.00036 mrad 40 mrad Noble gas gamma ray air dose 0.00031 mrad 20 mrad Noble gas dose to the skin 0.00059 mrem 30 mrem Noble gas dose to the whole body 0.00028 mrem 10 mrem

The results show that during 2006, the doses from PBNP effluents were a small percentage (0.10% at the most) of the Appendix I design objectives and therefore operation of PBNP continues to be ALARA.

A survey of land use with respect to the location of dairy cattle was made pursuant to Section 2.5 of the PBNP Environmental Manual. Currently, farm land that adjoins site property is not used for cattle grazing. Therefore, the assumption that cattle graze at the site boundary used in the evaluation of doses from PBNP effluents remains conservative.

The 2006 Radiological Environmental Monitoring Program (REMP) collected 805 samples for radiological analyses and 1 15 sets of thermoluminescent dosimeters (TLDs) to measure ambient radiation in the vicinity of PBNP and the Independent Spent Fuel Storage Installation (ISFSI). Air monitoring from six different locations showed only background radioactivity from naturally occurring radionuclides. Terrestrial monitoring consisting of soil, vegetation, and milk found no influence from PBNP.

Similarly, samples from the aquatic environment, consisting of lake and well water, fish, and algae, revealed no buildup of PBNP radionuclides released in liquid effluents.

Therefore, the data showed no plant effect on its environs.

Five NUHOMS dry storage units were added to the ISFSl in 2006, for a total of 25 dry storage casks at the ISFSI. Sixteen are the ventilated, vertical storage casks (VSC-24) and nine are the NUHOMS, horizontally stacked storage modules. The subset of the PBNP REMP samples used to evaluate the environmental impact of the PBNP ISFSl showed no environmental impact from its operation.

The environmental monitoring conducted during 2006 confirmed that the effluent control program at PBNP ensured a minimal impact on the environment.

Part A EFFLUENT MONITORING

1.0 INTRODUCTION

The PBNP effluent monitoring program is designed to comply with federal regulations for ensuring the safe operation of PBNP with respect to releases of radioactive material to the environment and its subsequent impact on the public.

Pursuant to 10 CFR 50.34a, operations should be conducted to keep the levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA). In 10 CFR 50, Appendix I, the Nuclear Regulatory Commission (NRC) provides the numerical values for what it considers to be the appropriate ALARA design objectives to which the licensee's calculated effluent doses may be compared. These doses are a small fraction of the dose limits specified by 10 CFR 20.1 301 and lower than the Environmental Protection Agency (EPA) limits specified in 40 CFR 190.

10 CFR 20.1 302 directs PBNP to make the appropriate surveys of radioactive materials in effluents released to unrestricted and controlled areas. Liquid wastes are monitored by inline radiation monitors as well as by isotopic analyses of samples of the waste stream prior to discharge from PBNP. Airborne releases of radioactive wastes are monitored in a similar manner. Furthermore, for both liquid and atmospheric releases, the appropriate portions of the radwaste treatment systems are used as required to keep releases ALARA. Prior to release, results of isotopic analyses are used to adjust the release rate of discrete volumes of liquid and atmospheric wastes (from liquid waste holdup tanks and from gas decay tanks) such that the concentrations of radioactive material in the air and water beyond PBNP are below the PBNP Technical Specification concentration limits for liquid effluents and release rate limits for gaseous effluents.

Solid wastes are shipped offsite for disposal at NRC licensed facilities. The amount of radioactivity in the solid waste is determined prior to shipment in order to determine the proper shipping configuration as regulated by the Department of Transportation and the NRC.

Also operated at PBNP, under the General License granted pursuant to 10 CFR 72.210, is an Independent Spent Fuel Storage Installation (ISFSI). The release of radioactive materials from the operation of the ISFSl must also comply with the limits of Part 20 and Part 50 Appendix I design objectives. Per 10 CFR 72.44(d)(3), the results of radiological effluent monitoring are to be

reported annually. The dose criteria for effluents and direct radiation specified by 10 CFR 72.1 04 states that during normal operations and anticipated occurrences, the annual dose equivalent to any real individual beyond the controlled area must not exceed 25 mrem to the whole body, 75 mrem to the thyroid and 25 mrem to any other organ. The dose from naturally occurring radon and its decay products are exempt. Because the loading of the storage casks occurs within the primary auxiliary building of PBNP, the doses from effluents due to the loading process will be assessed and quantified as part of the PBNP Radiological Effluent Control Program.

2.0 RADIOACTIVE LIQUID RELEASES The radioactive liquid release path to the environment is via the circulating water discharge. A liquid waste treatment system in conjunction with administrative controls is used to minimize the impact on the environment and maintain doses to the public ALARA from the liquid releases.

2.1 Doses From Liquid Effluent Doses from liquid effluent are calculated using the methodology of the Offsite Dose Calculation Manual (ODCM). These calculated doses use parameters such as the amount of radioactive material released, the total volume of liquid, the total volume of dilution water, and usage factors (e.g., water and fish consumption, shoreline and swimming factors).

These calculations produce a conservative estimation of the dose. For compliance with 10 CFR 50, Appendix I design objectives, the annual dose is calculated to the hypothetical maximally exposed individual (MEI).

The ME1 is assumed to reside at the site boundary in the highest X/Q sector and is maximized with respect to occupancy, food consumption, and other uses of this area. As such, the ME1 represents an individual with reasonable deviations from the average for the general population in the vicinity of PBNP. A comparison of the calculated doses to the 10 CFR 50, Appendix I design objectives is presented in Table 2-1. The conservatively calculated dose to the ME1 is a very small fraction of the Appendix I design objective.

2.2 2006 Circulatinq Water Radionuclide Release Summaw Radioactive liquid releases via the circulating water discharge are summarized by individual source and total curies released on a monthly basis and presented in Table 2-2. These releases are composed of processed waste, wastewater effluent, and blowdown from Units 1 and 2.

The wastewater effluent consists of liquid from turbine hall sumps, plant well house backwashes, sewage treatment plant effluent, water treatment plant backwashes and the Unit 1 and 2 facade sumps.

2.3 2006 Isotopic Composition of Circulatinq Water Discharqes The isotopic composition of circulating water discharges during the current reporting period is presented in Table 2-3. The noble gases released in liquids are reported with the airborne releases, Section 3. The isotopic distribution shows little change from 2005, with tritium up slightly from 2005 and close to 2004 value. H-3 continues to be the major radionuclide released via liquid discharges.

2.4 Beach Drain Svstem Releases Tritium Summaw The quarterly and annual results of beach drain monitoring are presented in Table 2-4. These six drains are sampled once a month. The total monthly flow is calculated assuming that the flow rate at the time of sampling persists for the whole month. During 2006, no tritium was observed in any of the beach drains at the effluent LLDs used to detect and quantify H-3 released from discreet volumes such as hold up tanks and waste distillate tanks. However, special samples obtained in September and sent to the contracted REMP laboratory did detect H-3 in the 100-300 pCi/l range (Part D page 44). Assuming that the highest concentration of 328 pCi/l was maintained for the third and fourth quarters in drains S-1 and S-2, an additional 1.2E-03 Ci of H-3 would have been released. Compared to the 6.07E+02 Ci released via the normal discharge pathway, the beach drain contribution is small. The resulting beach drain dose is about 11250,000 of that resulting from the normal liquid discharges shown in Table 2-1.

2.5 Chanqes to the Waste Liquid Treatment System in 2006 There were no changes to the liquid waste treatment system in 2006.

This sewage sludge, which may contain trace amounts of radionuclides, is to be applied in accordance with methodologies approved by the NRC on January 13, 1988, pursuant to 10 CFR 20.302(a). The approved methodology requires analyses prior to every disposal. Based upon an investigation of the source of the radionuclides, a combination of engineering modifications and administrative controls has eliminated plant generated radiological inputs to the sewage. This was verified by sludge analyses using the environmental lower level of detection (LLD) criteria. No byproduct radionuclides were found in the sludge after the controls and modifications were completed. Sludge is routinely monitored and no radionuclides attributable to PBNP have been found.

There was no disposal of sewage by land application during 2006. All disposals were done at the Manitowoc Sewage Treatment Plant.

3.0 RADIOACTIVE AIRBORNE RELEASES The release paths to the environment contributing to radioactive airborne release totals during this reporting period were the Auxiliary Building Vent Stack, the Drumming Area Vent Stack, the Letdown Gas Stripper, the Unit 1 Containment Purge Stack, and the Unit 2 Containment Purge Stack. A gaseous radioactive effluent treatment system in conjunction with administrative controls is used to minimize the impact on the environment from the airborne releases and maintain doses to the public ALARA.

3.1 Doses From Airborne Effluent Doses from airborne effluent are calculated for the maximum exposed individual (MEI) following the methodology contained in the PBNP ODCM. These calculated doses use parameters such as the amount of radioactive material released, the concentration at and beyond the site boundary, the average site weather conditions, the locations of the exposure pathways (e.g., cow milk, vegetable gardens and residences), and usage factors (e.g., breathing rates, food consumption). In addition to the ME1 doses, the energy deposited in the air by noble gas beta particles and gamma rays is calculated and compared to the corresponding Appendix I design objectives. A comparison of the annual Appendix I design objectives for atmospheric effluents to the highest organ dose and the noble gas doses calculated using ODCM methodology is listed in Table 3-1. The doses demonstrate that releases from PBNP to the atmosphere continue to be ALARA.

3.2 Radioactive Airborne Release Summary Radioactivity released in airborne effluents for 2006 are summarized in Table 3-2.

3.3 Isotopic Airborne Releases The monthly isotopic airborne releases for 2006, from which the airborne doses were calculated, are presented in Table 3-3. When both the equipment hatch and the 66' elevation hatch are open during an outage, there is a measurable, convective flow out the upper hatch. Because this air is not filtered, containment air is assumed to be carried out the hatch, through the fagade, and into the environment thereby contributing to the particulate effluent and the calculated dose. This was done for the Unit 2 fall outage.

Part C RADIOLOGICAL ENVIRONMENTAL MONITORING

8.0 INTRODUCTION

The objective of the PBNP Radiological Environmental Monitoring Program (REMP) is to determine whether the operation of PBNP or the ISFSl has radiologically impacted the environment. To this end, the REMP collects and analyzes air, water, milk, soil, vegetation, and fish samples for radionuclides and uses TLDs to determine the ambient radiation background. These measurements also serve as a check of the efficacy of PBNP effluent controls.

The REMP fulfills the requirements of 10 CFR 20.1302, PBNP General Design Criterion (GDC) 17, GDC 64 of Appendix A to 10 CFR 50, and Sections IV.B.2 and IV.B.3 of Appendix I to 10 CFR 50 for the operation of the plant. Therefore, the REMP collects samples from various environmental media in order to provide data on measurable levels of radiation and radioactive materials in the principal pathways of environmental exposure.

A subset of the PBNP REMP samples, consisting of air, soil, and vegetation, also fulfills 10 CFR 72.44(d)(2) for operation of the ISFSI. Additionally, thermoluminescent dosimeters (TLDs) provide the means to measure changes in the ambient environmental radiation levels at sites near the ISFSl and at the PBNP site boundary to ensure that radiation levels from the ISFSl are maintained within the dose limits of 10 CFR 72.104. Because the ISFSl is within the PBNP site boundary, radiation doses from PBNP and the ISFSI, combined, must be used to assess compliance with 10 CFR 72.122 and 40 CFR 190. Therefore, radiological environmental monitoring for the ISFSl is provided by selected sampling sites, which are part of the PBNP REMP.

For the aquatic environment, the samples include water as well as the biological integrators, such as fish and filamentous algae. Because of their migratory behavior, fish are wide area integrators. In contrast, the filamentous algae periphyton is attached to shoreline rocks and concentrate nuclides from the water flowing by their point of attachment. Grab samples of lake water provide a snapshot of radionuclide concentrations at the time the sample is taken; whereas analysis of fish and filamentous algae yield concentrations integrated over time.

The air-grass-cow-milk exposure pathway unites the terrestrial and atmospheric environments. This pathway is important because of the many dairy farms around PBNP. Therefore, the REMP includes samples of air, general grasses, and milk from the PBNP environs. An annual land use survey is made to determine whether the assumptions on the location of dairy cattle remain conservative with respect to dose calculations for PBNP effluents. The dose calculations assume that the dairy cattle are located at the south site boundary,

the highest depositional sector. In addition, soil samples are collected and analyzed in order to monitor the potential for long-term buildup of radionuclides in the vicinity of PBNP.

For the measurement of ambient environmental radiation levels that may be affected by direct radiation from PBNP or by noble gas effluents, the REMP employs a series of TLDs situated around PBNP and the ISFSI.

9.0 PROGRAM DESCRIPTION 9.1 Results Reportinq Convention The vendor used by PBNP to analyze the environmental samples is directed to report analysis results as measured by a detector, which can meet the required lower level of detection (LLD) as specified in Table 2-2 of the Environmental Manual for each sample. The report provided by the vendor (see Appendix 1) contains values, which can be either negative, positive or zero plus/minus the two sigma counting uncertainty, which provides the 95% confidence level for the measured value.

The lower limit of detection (LLD) is an a priori concentration value that specifies the performance capability of the counting system used in the analyses of the REMP samples. The parameters for the a priori LLD are chosen such that only a five percent chance exists of falsely concluding a specific radionuclide is present when it is not present at the specified LLD.

Based on detector efficiency and average background activity, the time needed to count the sample in order to achieve the desired LLD depends upon the sample size. Hence, the desired LLD may be achieved by adjusting various parameters. When a suite of radionuclides are required to be quantified in an environmental sample such as lake water, the count time used is that required to achieve the LLD for the radionuclide with the longest counting time. Therefore, in fulfilling the requirement for the most difficult to achieve radionuclide LLD, the probability of detecting the other radionuclides is increased because the counting time used is longer than that required to achieve the remaining radionuclide LLDs.

The REMP results in this report are reported as averages of the measurements made throughout the calendar year pluslminus the associated standard deviation. If all net sample concentrations are equal to or less than zero, the result is reported as "Not Detectable" (ND),

indicating no detectable level of activity present in the sample. If any of the net sample concentrations indicate a positive result statistically greater than zero, all of the data reported are used to generate the reported statistics. Because of the statistical nature of radioactive decay, when the radionuclide of interest is not present in the sample, negative and positive results centered about zero will be seen. Excluding validly

measured concentrations, whether negative or as small positive values below the LLD, artificially inflates the calculated average value.

Therefore, all generated data are used to calculate the statistical values (i.e., average, standard deviation) presented in this report.

In interpreting the data, effects due to the plant must be distinguished from those due to other sources. A key interpretive aid in assessment of these effects is the design of the PBNP REMP, which is based upon the indicator-control concept. Most types of samples are collected at both indicator locations (e.g., nearby, downwind, or downstream) and at control locations (e.g., distant, upwind, or upstream). A plant effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuation in radiation levels arising from other sources.

9.2 Samplinq Parameters Samples are collected and analyzed at the frequency indicated in Table 9-1 from the locations described in Table 9-2 and shown in Figures 9-1, 9-2 and 9-3. (The latter two figures show sampling locations not shown in preceding figures due to space limitations. The location of the former retention pond, retired and remediated to NRC unrestricted access criteria, is indicated in Fig. 9-3). The list of PBNP REMP sampling sites used to determine environmental impact around the ISFSl is found in Table 9-3. The minimum acceptable sample size is found in Table 9-4. In addition, Table 9-1 indicates the collection and analysis frequency of the ISFSl fence TLDs.

9.3 Deviations from Required Collection Frequencv Deviations from the collection frequency given in Table 9-1 are allowed in accordance with Section 2.2.6 of the Environmental Manual. Table 9-5 lists the deviations from the scheduled sampling frequency that occurred during the reporting period.

9.4 Assistance to the State of Wisconsin The Radiation Protection Unit of the Wisconsin Department of Health and Family Services maintains a radiological environmental monitoring program in order to confirm the results from the PBNP REMP. As a courtesy to the State of Wisconsin, PBNP personnel also collect certain environmental samples (Table 9-6) for the State from sites that are near PBNP sampling sites, or are co-located. The results of the State monitoring program are available from the Radiation Protection Unit of the Wisconsin Department of Health and Family Services.

9.6 Analvtical Parameters The types of analyses and their frequencies are given in Table 9-1. The LLDs for the various analyses are found in the Section 10 (Table 10-1) with the summary of the REMP results. All environmental LLDs listed in Table 2-2 of the Environmental Manual (also in Table 10-1) were achieved during 2006.

9.7 Brief Description of Analvtical Parameters in Table 9-1 9.7.1 Gamma isotopic analysis Gamma isotopic analysis consists of a computerized scan of the gamma ray spectrum from 80 keV to 2048 keV. Specifically included in the scan are Mn-54, Fe-59, Co-58, Co-60, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141 and Ce-144. However, any other detected nuclear power plant produced radionuclides also are noted. All of the above radionuclides detected by gamma isotopic analysis are decay corrected to the time of collection. Frequently detected, but not normally reported here, are the naturally occurring radionuclides Ra-226, Bi-214, Pb-212, TI-208, Ac-228, Be-7 and K-40.

9.7.2 Gross Beta Analysis Gross beta analysis is a non-specific analysis that consists of measuring the total beta activity of the sample. No individual radionuclides are identifiable by this method. Gross beta analysis is a quick method of screening samples for the presence of elevated activity that may require additional, immediate analyses.

9.7.3 Water Samples Water samples include both Lake Michigan and well water. The Lake Michigan samples are collected along the shoreline at two locations north and two locations south of PBNP. The well water is sampled from the on-site PBNP well. Gross beta and gamma isotopic analytical results for water are obtained by measurements on the solids remaining after evaporation of the unfiltered sample to dryness. Hence, the results are indicated as "on total solids" in Table 10-1.

9.7.4 Air Samples Particulate air filters are allowed to decay at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> before gross beta measurements are made in order for naturally occurring radionuclides to become a negligible part of the total activity.

Gross beta measurements serve as a quick check for any unexpected activity that may require immediate investigation.

Quarterly composites of the particulate air filters are analyzed for long-lived radionuclides such as Cs-134 and Cs-137. Charcoal canisters for radioiodine are counted as soon as possible so the 1-131 will undergo only minimal decay prior to analyses. The weekly charcoal canisters are screened for 1-131 by counting them at the same time to achieve a lower LLD. If a positive result is obtained, each canister is counted individually.

In order to ensure that the air sampling pumps are operating satisfactorily, a gross leak check is performed weekly. The pumps are changed out annually for calibration and maintenance beyond what can be accomplished in the field.

9.7.5 Vegetation Vegetation samples consist predominantly of green, growing plant material (grasses and weeds most likely to be eaten by cattle if they were present at the sampling site). Care is taken not to include any dirt associated with roots by cutting the vegetation off above the soil line.

9.7.6 Environmental Radiation Exposure The 2006 environmental radiation exposure measurements were made using thermoluminescent dosimeter (TLD) cards. The TLD card is a small passive detector, which integrates radiation exposure. Each TLD consists of a Teflon sheet coated with a crystalline, phosphorus material (calcium sulfate containing dysprosium) which absorbs the gamma ray energy deposited in them. Each TLD is read in four distinct areas to yield four exposure values which are averaged. Prior to the third quarter of 2001, exposure data were obtained using three lithium fluoride (LiF) TLD chips sealed in black plastic. The difference in material types can impact the amount of exposure measured. As seen in 2001, the Environmental Inc. TLD cards typically produce a slightly higher measured exposure value, although within the uncertainty of that value recorded by the TLD chips.

The reported field exposure is the arithmetic average of the four exposure values obtained minus the exposure received while the field TLD is in storage and transit.

The gamma rays may originate from PBNP produced radionuclides or from naturally occurring radionuclides. The TLDs remain at the monitoring site for roughly three months prior to analyses and the results are reported as mrem per seven days. Because the TLDs are constantly bombarded by naturally occurring gamma radiation, even during shipment to and from PBNP, the amount of exposure during transportation is measured using transportation controls with each shipment of TLDs to and from the laboratory. The doses recorded on the transportation controls are subtracted from the monitoring TLDs in order to obtain the net in situ dose.

9.7.7 ISFSl Ambient Radiation Exposure Although the ISFSI fence TLDs are not considered part of the REMP because of their location directly on site, their results can be used indirectly to determine whether the operation of the ISFSl is having an impact on the ambient environmental radiation beyond the site boundary. Impacts are determined by comparison of fence TLD results to the results of the monitoring at PBNP site boundary and other selected locations.

10.0 RESULTS Summaw of 2006 REMP Results Radiological environmental monitoring conducted at PBNP from January 1 through December 31, 2006, consisted of analysis of air filters, milk, lake water, well water, soil, fish, shoreline sediments, algae, and vegetation as well as TLDs.

The results are summarized in Table 10-1.

Table 10-1 contains the following information:

Sample: Type of the sample medium

Description:

Type of measurement LLD: a priori lower limit of detection N: Number of samples analyzed Average: Average value + the standard deviation of N samples High: Highest measured value + its associated 2 sigma counting error Units: Units of measurement

For certain analyses, an LLD, which is lower than that required by REMP, is used because the lower value derives from the counting time required to obtain the LLDs for radionuclides that are more difficult to detect. For these analyses, both LLDs are listed with the REMP LLD given in parentheses. The results are discussed in the narrative portion of this report (Section 11). Blank values have not been subtracted from the results presented in Table 10-1. A complete listing of all the individual results obtained from the contracted analytical laboratory and the laboratory's radioanalytical quality assurance results and lnterlaboratory Crosscheck Program results are presented in Appendix A.

In Table 10-1, no results are reported as <LLD. A non-detectable (ND) radionuclide is one for which none of the individual measurements was statistically different from zero. When one or more of the measured radionuclide concentrations was positive and statistically different from zero, the average reported in Table 10-1 is the average & one standard deviation. Both the positive and negative results were used to calculate the average and standard deviation.

Some of the reported averages are negative because many of the measured concentrations for that sample category were negative. The highest positive value and its 2-sigma error are reported only when one or more measured values are statistically greater than zero.

The method of determining averages follows the recommendation made in NUREG-0475 (1978) "Radiological Environmental Monitoring by NRC Licensees for Routine Operations of Nuclear Facilities Task Force Report," and in Health Physics Society Committee Report HPSR-1 (1980) "Upgrading Environmental Radiation Data" released as document EPA 52011-80-012 and in more recent documents such as ANSl N42.23-1996, "Instrument Quality Assurance for Radioassay Laboratories;" ANSl N13.30-1996, "Performance Criteria for Radiobioassay;" and DE91-013607, "Environmental Regulatory Guide for Radiological Effluent Monitoring and Environmental Surveillance."

Table 10-2 contains the ISFSl fence TLD results.

Table 10-2 ISFSl Fence TLD Results for 2006 South West 11.0 DISCUSSION 11.1 TLD Cards The ambient radiation was measured in the general area of the site boundary, at an outer ring four to five miles from the plant, at special interest areas, and at one control location, roughly 17 miles southwest of the plant. The average of the indicator TLD cards is 1.14 mW7-days and 1.I1 mW7-days at the control location. These results are not significantly different from each other nor from those observed from 2001 through 2005 (tabulated below in Table 11-1). This comparison holds even though the fourth quarter TLDs were accidentally X-rayed upon arrival.

This resulted in an approximate 25% increase for the fourth quarter TLD results: 1.36 + 0.1 8 vs. 1.06 + 0.1 6 for the indicator sites and 1.37 + 0.1 7 vs. 1.02 + 0.08 for the background site, E-20. The change in TLD types in 2001 accounts for the increase in average TLD readings from 2000 to 2001. (Prior to third quarter 2001 TLD LiF chips were used versus the TLD cards, see section 9.7.6 for additional information.) Therefore, the operation of the plant has had no effect on the ambient gamma radiation.

There were five new cask additions in 2006 with no significant change in the average annual ISFSl fence TLD results (Table 11-2) The North and West fence TLDs continue to record higher doses than the South and East fence TLDs (Table 11-2) corresponding to the location of the storage units at the NW corner of the site. Compared to the background site (E-20), most of the indicator sites for the ISFSl (Table 11-3) show increases with the placement of casks at the ISFSl with the highest values at E-03 which is the closest to the ISFSl [see Figs. 9-1 and 9-2 for locations]. The results near the site boundary (E-31, E-32) are comparable to the background site E-20, within the associated measurement error, indicating no measurable increase in ambient gamma radiation at the site boundary due to the operation of the ISFSI.

Except for Sr-90, the annual average radionuclide concentrations in milk continue to be statistically not different from zero. The few statistically positive, individual monthly results for BdLa-140 (3 of 36) and "Other"( in this case, Co-60) (1 of 36) are attributed to variations in the analyses resulting from the statistical nature of radioactive decay. This conclusion is supported by the fact that PBNP did not release BdLa-140 during 2006 and that the one positive "other" (Co-60) result occurred in June whereas PBNP recorded Co-60 releases during October and November of 2006.

The Sr-90 concentrations result from the cycling of this radionuclide in the biosphere after the large-scale atmospheric weapons tests of the '50s,

'60s, and '70s and the Chernobyl accident. Although these tests also introduced Cs-137 into the environment, Cs-137 binds more strongly to soils and therefore less likely to be ingested. As summarized in Table 3-

2. PBNP did not release any airborne Sr-90 in 2006. This was true in 2005 as well (see Table 3-2 of the 2005 AMR). The 2006 average Sr-90 (0.9 + 0.3) is equivalent to previous years: 0.9 + 0.4 pCi/L in 2005, 1.1 +

These results are common throughout the Great Lakes region and North America. Therefore, it is concluded that the milk data for 2006 show no radiological effects of the plant operation.

The average annual gross beta concentrations (plus/minus the one-sigma uncertainty) in weekly airborne particulates at the indicator and control locations were 0.021 + 0.007 pci/m3 and 0.021 + 0.006 p ~ i / m 3 ,

respectively, and are similar to levels observed from 1993 through 2005 (Table 11-4).

Table 11-4 Average Gross Beta Measurements in Air

The gross beta concentration variation over the year usually reveals higher concentrations in the fall and winter as compared to the spring and summer. This is present again during 2006. However, for 2006 another high period during July-September also is apparent (Figure 11-1). This pattern will be monitored for during 2007. Similarly to 2005, there is more scatter in the data for the spring and summer months.

Instead of counting each charcoal cartridge separately, all six cartridges for the week are counted as one sample in a predetermined geometry to screen the samples for 1-131. If any airborne radioiodine were detected, each sample cartridge is counted individually. With no detectable 1-131, the reported analytical result is the minimum detectable activity (MDA) conservatively calculated using the smallest of the six sample volumes.

The reported MDAs ranged from 0.005 to 0.030 p ~ i / m 3 Because

. the analysis LLD is based on counting only one cartridge, the use of six cartridges or roughly six times the sample volume with the same count time as would be needed to achieve the desired LLD for only one sample, the actual LLD is about six times lower than the programmatic value given in Table 10-1. Similarly, the actual MDA is about one-sixth of that reported, or in the range of 0.001 to 0.005 p ~ i / m 3Therefore,

. because no 1-131 was detected, it is concluded that the release of small amounts of radioiodine during February, March, and November (Table 3-2) had no measurable impact on the environment.

Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Neither

the indicator nor the control locations show results which, on average, are significantly different than zero. The one small, positive value for Cs-137 occurred at only one site during the third quarter in which PBNP released small amounts of Cs-137 on the order of 1E-08 to 1E-10 Ci (Table 3-2).

No other sites had statistically positive airborne Cs-137. This result may be a false positive attributable to the statistical variation in radioactive decay. Similarly, there was one, first quarter, positive Co-60 ("other" category) result at the background site. Because no airborne Co-60 was released that quarter, this, also is concluded to be a false positive result.

Be-7, a naturally occurring radionuclide, was measured in quarterly composites of all indicator samples with an average of 0.070 pcilm3. This is comparable to the average of 0.082 p ~ i / mat 3 the control site. Be-7 is not required to be measured by the PBNP REMP; however, it serves as a means to monitor the internal consistency of the vendor's analytical program and for comparisons to radionuclides that may be in PBNP airborne effluent.

In summary, the air data for 2006 demonstrates the operation of PBNP did not have an impact on the surrounding environment.

11.4 Lake Water For the suite of REMP-specified gamma emitting radionuclides listed in Table 10-1, reported concentrations continue to occur as small negative and positive values scattered around zero, indicating no radiological impact from the operation of PBNP. Of the 48 lake water samples analyzed during 2006, 1 of 48 was statistically greater than zero for Cs-134, Cs-137, and Zr-Nb-95; 2 of 48 were positive for Mn-54; 3 of 48 for BaILa-140; 3 of 48 for Co-58 and Co-60; and finally, 5 of 48 for Fe-59. No Fe-59 was released by PBNP during 2006. Based on these results, it is concluded that the impact is minimal for these nuclides.

Aliquots of the monthly samples are composted quarterly and analyzed for Sr-89/90 and for tritium. Sr-90 still persists in Lake Michigan from radioactive fallout. Tritium, in addition to being produced by water-cooled reactors such as PBNP, also is a naturally occurring radionuclide. The quarterly composite lake water samples collected and analyzed in 2006 for H-3 range from ND (non-detectable) to 1017 pCi/l (fourth quarter) at a site four miles north of PBNP near the Kewaunee Power Station (KPS).

Because typical REMP H-3 values are in the range of 100-400 pCi/l, the individual months of July - September from this sampling site were analyzed for tritium with the following results: July, 70 + 85; August, 129 & 87; and September, 3096 169. The 3096 pCi/l value is 0.31 O h of the liquid effluent concentration limit of 10 CFR 20, Appendix B, Table 2.

Based on the monthly results, it is concluded that the PBNP sample was obtained shortly after a KPS discharge about 4 miles north of this

sampling site. A similar circumstance occurred in 2005. Without the September result, the quarterly average is 100 & 42 pCi/l. By the time the water mass reached the REMP sampling point immediately south (0.5 miles) of PBNP, dilution had reduced the average quarterly H-3 concentration to 124 pCi/l. These results indicate a minimal impact upon the waters of Lake Michigan from PBNP liquid discharges.

Filamentous algae attached to rocks along the Lake Michigan shoreline are known to concentrate radionuclides from the water with concentration factor over a thousand for certain radionuclides. Only one (1 of 6) small, positive concentration of Co-58 was found and that was near the PBNP discharge point. PBNP released Co-58 in 10 of the 12 months of 2006.

No Cs-137 was found. Typically, the only fission product observed in algae is Cs-137 with averages over years 1995-2004 of 0.034, 0.050, 0.030, 0.027, 0.031, 0.027, 0.019, 0.019, 0.010 and 0.018 pCi/g; all of which are less than the LLD (0.25 pCi/g). The concentrations of naturally occurring Be-7 and K-40 are higher: 0.93 and 2.07 pCi/g, respectively.

These results indicate only a minor effect upon the PBNP environment.

No specified fission/corrosion radionuclide concentrations in fish greater than the required LLD were found in 2006. Statistically positive Cs-137 concentrations were found in 8 of the 10 fish. The highest Cs-137 value of 0.055 pCi/g is lower than the high of 0.172 pCi/g in 2005. Both values are considerably less than the high of 2.8 pCi/g as seen in PBNP samples obtained in the mid-1970s during the Chinese weapons tests. However, the Cs-137 results in fish are consistent with accumulation due to the recycling of atmospheric weapons testing fallout Cs-137 in Lake Michigan.

Again, the aforementioned resuspension events make the Cs-137 more readily available to be associated with items eaten by the fish. By comparison, the concentration of naturally occurring K-40 (1.58-4.41 pCi/g) is about 30-80 times higher than the highest 0 - 1 3 7 concentration. Therefore, it is concluded that there is no indication of a plant effect.

11.7 Well Water There were three well water results statistically greater than zero. In the third quarter, Co-58 was statistically above zero and in the fourth quarter, Sr-90 and Zr-Nb-95 were statistically above zero. These results are concluded to be false positives because the impermeability of the clay layer which separates the surface ground water from the aquifer from which the PBNP well water is obtained precludes surface water from

reaching the lower aquifer. There are no release pathways which could get these radionuclides to the well water aquifer. Radionuclides would have to flow against the hydrological gradient which is from the well to the lake. The well is located west of the plant. As previously mentioned, small, positive results may occur due to the statistical nature of radioactive decay, when there is no radionuclide present. Therefore, it is concluded that these results do not indicate that PBNP effluents are getting into the aquifer supplying drinking water to PBNP.

0 - 1 3 7 is present in the soils throughout North America and the world.

The main contributor to this worldwide distribution is the weapons testing in the 1950s and 1960s with lesser amounts from Chinese atmospheric nuclear tests in the 1970s and the 1986 Chernobyl accident. Soil is an integrating sample media in that it is a better indicator of long term buildup of 0 - 1 3 7 as opposed to current deposition for local sources. The main modifiers of soil Cs-137 concentration levels are erosion and radioactive decay. The PBNP REMP results indicate that low levels of Cs-137 from fallout continue to be present in soil samples at about 1% of the levels of naturally occurring K-40. Fifteen of the 16 samples have Cs-137 concentrations statistically greater than zero ranging from 0.02 + 0.01 to 0.67 + 0.07 pCi/g The current gross beta results also are consistent with previous years (Table 11-5). Therefore, there is no indication of a plant effect.

11.9 Shoreline Sediment Shoreline sediment consists of sand and other sediments washed up on the Lake Michigan shore. As in soil samples, the only non-naturally occurring radionuclide found in these samples is Cs-137. Eight of the ten samples have Cs-137 concentrations statistically different from zero. The Cs-137 concentrations of the shoreline sediment are about one-tenth of that found in soils. This is expected because Cs-137 in the geological media is bound to clay as opposed to the sand found on the beach.

Wave action winnows clay particles from the beach leaving the heavier sand; hence the lower Cs-137 concentrations in beach samples. In contrast to K-40 which is actually part of the minerals making up the clay and sand, Cs-137 is attached to soillsand particle surfaces and is present at concentrations 1% or less of the naturally occurring concentrations of K-40. Because Lake Michigan sediments are a known reservoir of fallout Cs-137, the shoreline sediment data indicate no radiological effects from plant operation.

11.10 Veaetation The naturally occurring radionuclides Be-7 and K-40 are found in all of the vegetation samples. In contrast, the programmatically specified radionuclide Cs-134 was not detected. 1-131 was statistically different from zero in 3 of 24 vegetation samples. All three occurrences were in July. PBNP released small amounts of airborne 1-131 in February, March and November of 2006. Because of its 8-day half life, any 1-131 would be roughly one million times lower based on radioactive decay. Dilution during the transit to the sites where these positive results were obtained would lower the concentrations even more. Therefore, it is concluded that the 1-131 detected at three sites during July are false positives.

Cs-137 was detected in 2 of the 24 samples. Both occurrences were at site E-06. All the positive Cs-137 results were below the required LLD at concentrations about 100 times lower than Be-7 and K-40 concentrations. The source of Be-7 is atmospheric deposition. It is continuously formed in the atmosphere by cosmic ray spallation of oxygen, carbon, and nitrogen atoms. In contrast, K-40 is a primordial radionuclide which is incorporated into vegetation from the soil during the growing process. Cs-137 can represent both pathways. Fresh Cs-137 fallout is associated, like Be-7, with deposition on the plant surface. Old fallout from the '50s and '60s is now being incorporated into growing plants in the same manner as potassium because it is in the same chemical family as potassium. Cs-137 has been consistently present in vegetation from E-06, a campground area in the Point Beach State Forest. As has been demonstrated at other sites in the United States which are far from any nuclear plants, 1950s and 1960s fallout Cs-137 is

present in the ash produced by burning the wood in fireplaces. Typically, campground fires are put out using water and the ashes are spread on the ground. The ash acts as a fertilizer, releasing the cesium and potassium into the soil where they are available for uptake by growing plants and trees. Hence, the Cs-137 results from E-06 demonstrate that Cs-137 fallout from the Chernobyl accident and from atmospheric weapons tests continues to be recycled in the environment by the spreading of wood ash at camp sites.

Based on the 2006 vegetation sampling results, it is concluded that no effect from PBNP effluents are indicated.

11.11 Land Use Census In accordance with the requirements of Section 2.5 of the Environmental Manual, a visual verification of animals grazing in the vicinity of the PBNP site boundary was completed in 2006, to ensure that the milk sampling locations remain as conservative as practicable. No significant change in the use of pasturelands or grazing herds was noted. Therefore, the existing milk-sampling program continues to be acceptable. The assumption of grazing animals at the south boundary continues to be conservative for the purpose of calculating doses via the grass-cow-milk pathway. It should be noted that the plant entrance is at the south boundary. Therefore, an appearance of grazing animals at this location is readily visible.

12.0 REMP CONCLUSION Based on the analytical results from the 805 environmental samples and from 115 sets of TLDs that comprised the PBNP REMP for 2006, PBNP effluents had no discernable, permanent effect on the surrounding environment.

These results demonstrate that the control of effluents from PBNP continues to be acceptable pursuant to the ALARA criteria of 10 CFR 50.34a.

I Part D GROUNDWATER MONITORING I 13.0 Program Description PBNP monitors groundwater for tritium. During 2006 the sampling program consisted of beach drains, intermittent creeks and the Energy Information Center (EIC) well, as well as the main plant well. In the 1980s, the beach drains entering Lake Michigan were found to contain tritium. The beach drains are the discharge points for yard drainage system which carries storm water runoff and are postulated to be infiltrated by groundwater. The source of H-3 for this pathway was concluded to be spent fuel pool leakage into the groundwater under the plant based on the observation that after modifications were made to the pool, the tritium concentrations decreased below delectability. Beach drain effluents continue to be monitored and are accounted for in the monthly effluent quantification process. Those results are reported in Section 2.4 of this Report.

The intermittent streams and the EIC well were added to the groundwater monitoring program in late 1990s when it was discovered that tritium diffusion from the then operable, earthen retention pond was observable in the intermittent streams which transverse the site in a NW to SE direction. These streams pass on the east and west sides of the former retention pond and empty into Lake Michigan about half a mile south of the plant near the site's meteorological tower. Because the EIC is downstream of the observed flow affected by the retention pond, samples from the EIC well were included in the monitoring. The intermittent stream samples track H-3 in the surface groundwater. The EIC well monitors the much deeper, drinking water aquifer from which the main plant well draws its water.

14.0 Results The results from the groundwater monitoring associated with the former retention pond are presented in Table 14-1. Like the main plant well results (Sections 10 and 1I ) , no tritium has been found in the EIC well which draws water from a similar depth. Studies conducted during the remediation of the retention pond revealed that the tritium was confined to the upper layer of soil which is separated from the deeper, drinking water aquifer by a thick, impermeable clay layer that extends from Wisconsin into Illinois. The current stream results reveal low level H-3 concentrations consistent with the previous results.

'NO samples available for February LLD for GW-04 is 142 LLD for GW-03 is 137 LLD for GW-04 is 151 LLD for GW-01 is 181 Values are presented as the measured value and the 95% confidence level counting error.

ND = not detectable i.e. the value is not statistically different from zero at the 95% confidence level.

Note that the LLD in Table 14-1 is different from month-to-month.

(See Section 9.1 for a further discussion of the LLD.) For a given set of circumstances, it is possible to obtain results which are statistically different from zero which results in false positives. This is most prone to happen at the low levels of activity encountered in these samples given the statistical nature of radioactive decay. For example, if the net count in the H-3 quantification is based on subtracting a predetermined, average background from the total gross count and the actual background at the time of analysis is higher than the average background, a higher net count will result yielding a higher net H-3 concentration. Statistical variability may account for the positive results at GW-04 for the months of July and September. Based on the known statistical background variability, it is concluded that two positive results at GW-04 are false positives resulting from fluctuations in background.

15.0 Additional Monitoring In support of the Nuclear Energy Institute Groundwater Protection Initiative, the groundwater monitoring program was expanded. Therefore, samples were obtained at a number of various locations around the site during 2006 (Table 15-1). In addition to the system of manholes used to access underground electrical conduits, water samples were obtained from the subsurface drainage (SSD) system under the plant. Samples also were obtained from two marshy areas on site. One is located on the north side of the plant (North Bog) and one is located south of the now closed and remediated retention pond (EIC Bog).

This latter site had been sampled as part of the retention pond closure/remediation project in 2002 and found to have tritium concentrations of 3000 pCi/l. The North Bog had not been previously sampled. In addition to these samples, the beach drain samples, currently analyzed as part of the effluent program, were sent to the REMP laboratory for analyses at environmental LLDs which are lower than the ones available onsite.

  • Error is the counting error at the 95% confidence level. The <MDA indicates that the sample result was below the minimum detectable activity 1

Second sample Results indicate that the manholes and SSDs around the plant, as well as the beach drains and bogs contain low levels of tritium. The manholes and the SSDs are not connected based on plant drawings. Because the manhole H-3 concentrations are lower that the SSD H-3 concentrations, it appears that the two systems may not be filled with groundwater from the same source. The

current SSD tritium may be the residual activity from the spent fuel pool leakage in the 1970s. There are no known sources for this tritium. [It should be noted that the 7 sampled SSDs were the only ones with water. Six others were dry and one was not accessible.] In comparison, the manholes, based on their proximity to the former retention pond, most likely represent groundwater which diffused out of the retention pond during its operation. The manhole H-3 values are more in line with the values obtained from the two intermittent streams (Table 14-1, GW-02 and GW-03). The EIC Bog results are an order of magnitude lower than the values found prior to the retention pond closure in 2002 indicating the pond was one source of the bog water. Supporting this conclusion is the observation that there is less water in the bog now than there was in 2002. The beach drain results are below the plant detection limits. These results indicate an interconnection with the manhole and SSD groundwater tritium source. A plant modification in 2002 connected the SSD system to the yard drains based on not finding any H - 3 in the SSD system using plant analytical LLDs. As expected, tritium was not detected in the SBCC well which draws water from the deep, drinking water aquifer. Finally, only the Unit 1 f a ~ a d ewell sample indicated the presence of H-3. The f a ~ a d ewells are stand pipes (2 per unit) that are used to sample the groundwater under each f a ~ a d eto determine the height of the groundwater and its chemical composition. These results indicate that the groundwater under Unit 1 may not be connected to the groundwater under Unit 2.

16.0 Groundwater Summary Groundwater monitoring indicates that low levels of tritium occur in the upper soil layer but not in the deep, drinking water aquifer. These results also indicate that the low levels of tritium are restricted to a small, well defined area close to the plant. This area is bounded by the streams around the former retention pond on the west and south and by the North Bog and yard drains on the north. This is in agreement with 1997 - 2002 surveys taken for the closure and remediation of the retention pond. These former surveys also indicated that there was no tritium outside of the plant boundary.

Based on the results in Table 15-1, the groundwater monitoring program has been expanded and modified for 2007. The SBCC well, the two bogs, the facade wells and the drinking water well for Warehouse #6 located on the north side of the property were permanently added to the program. The beach drain samples are to be sent to a vendor to be analyzed using the REMP tritium LLD.

Other sampling points will be added based on an ongoing evaluation of additional groundwater access points.

POINT BEACH NUCLEAR PLANT

1.0 INTRODUCTION

The following constitutes the final 2006 Monthly Progress Report for the Environmental Radiological Monitoring Program conducted at the Point Beach Nuclear Plant, Two Rivers, Wisconsin. Results of analyses are presented in the attached tables. Data tables reflect sample analysis results for both Technical Specification requirements and Special Interest locations and samples are randomly selected within the Program monitoring area to provide additional data for cross-comparisons.

For gamma isotopic analyses, the spectrum covers an energy range from 80 to 2048 KeV. Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected in soil and sediment samples. Specific isotopes listed are K-40, TI-208, Pb-212, Bi-214, Ra-226 and Ac-228. Unless noted otherwise, the results reported under "Other Gammas" are for Co-60 and may be higher or lower for other radionuclides.

All concentrations, except gross beta, are decay corrected to the time of collection.

All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.

Dear Mr. Schuelke:

Below are the results of the analyses for tritium in three monthly lake water samples.

Concentration H-3 (pCi/L)

Location Date Collected Lab Code Activity MDA For those isotopes where both an activity and an MDA value are given, the MDA value should be considered as the reportable value (based on a 4.66 sigma counting error for the background sample ) and the activity is presented for information only. For isotopes where an activity value is given, but no MDA value, the activity is considered the reportable value and the error given is the probable counting error at the 95% confidence level.

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

January, 2006 through December, 2006

Appendix A Interlaboratory Comparison Proqram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples 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 a laboratory's analytical procedures and to alert it of 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.

Results irr Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

The results in Table A-2 list results for thermoluminescent dosimeters (TLDs), via International lntercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NlST traceable 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.

The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.

Attachment A lists acceptance criteria for "spiked" samples.

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

2.0. Sinqle Measurements Each single measurement is reported as follows: x +s where: x = value of the measurement; s = 20 counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is less than the lower limit of detection L, it is reported as: < L, where L = the lower limit of detection based on 4.660 uncertainty for a background sample.

3.0. Du~licateanalyses 3.1 Individual results: For two analysis results; x, + s, and x, + s, Reported result: x t s: where x = (112) (x, + x,) and s = (112) 4 s : + si 3.2. Individual results: < 4, < Lz Re~ortedresult: c L, where L = lower of L, and L, 3.3. Individual results: x+s,<L Re~ortedresult: x t s if x 2 L; <L otherwise.

4,O. Computation of Averaoes 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  ; and standard deviation s of a set of n numbers x,, x2 . . . xn are defined as follows:

4.2 Values below the highest lower limit of detection are not included in the average.

4.3 If all 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 number following those to be retained is less than 5, the number is dropped, and the retained number s are kept unchanged. As an example, 11.443 is rounded off to 11.44.

4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 1 1.445 is rounded off to 11.45.
