SURVEY UNIT DESCRIPTION Survey Unit (SU) 9528-0003, (Southeast Mountain Side) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 10,000 m 2 (2.47 acres) of open land area located about a quarter of a mile (0.23 miles) from the center of the Haddam Neck Plant (HNP) Containment Building (see Attachment 1-Figure 1). SU 9528-003 is located between the Discharge Canal on the south and approximately fifteen (15) meters into the interior of area Survey Unit 9528-0000 on the north. Prior to FSS, activities associated with the Independent Spent Fuel Storage Installation (ISFSI) road construction occurred in this area.The area topography was altered with typical road building activities such as tree and stump removal, silt control, grading and backfilling.

Most of the survey unit was cleared of interfering vegetation and the Canal Road was brought to sub-grade.

The reference coordinates associated with the Southeast Mountainside survey unit are E022 through E033 by S104 through S124 (see License Termnination Plan Section 5.4.3). The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS).The historic files indicate that during the survey of 9528-0000, several areas were identified along the southern border of this area that possibly contained plant related radioactive materials.

Initially the area was subdivided into one survey unit, 9528-0001.

This area, located along the Discharge Canal, was approximately 5.75 acres and designated Class 2. During the scoping survey of Unit 9528-0001, plant related activity was identified in a soil sample collected in an area along the Canal Road. Based on area limitations from the License Termination Plan (LTP), the decision was made to subdivide area 9528-0001, and create three (3) new survey units, 9528-0002, 0003 and 0004. FSS samples and scan data related to 9528-0000, 0002, and 0004 areas are excluded from this report.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification

". The historical information and scoping analyses results provide sufficient data to designate SU 9528-0003 as Class 2 in August 2001.The "Classification Basis Summary" conducted for SU 9523-0000 consisted of: a) A review of the lOCFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and "Historic Site Assessment Supplement, " c) Historic and current survey records review, Revision 1 3 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD d) Personal interviews, e) Visual inspections and a "walk down." A review of the 1OCFR50.75 (g) (1) database report listed Condition Report (CR) 01-0490 in association with 9528-0003.

The CR was written during the FSS of Survey Unit 9528-0000 and identifies the possibility that radioactive material(s) were deposited near this location.

Although not specifically listed in the data base report, a CR listed for Survey Unit 9528-0002, CR 02-0125, further identifies plant related materials being found along the haul road in the adjacent survey unit.A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" provided no additional information pertinent to classification.

The Classification Basis Summary dated August 13, 2001 indicated that the creation of Survey Unit 9528-0003 resulted from the decision to subdivide Class 3 Survey Area 9528-0000 following FSS activities Samples collected during the FSS of SU 9528-0000 was used, in part, to develop the survey design of SU 9528-0003.

Cesium-137 was the only identified radionuclide in the sample analysis.

The levels of Cs-137 were consistent with the concentrations found in soil at offsite locations within the vicinity of the HNP as presented in Health Physics Technical Support Document (TSD) BCY-HP-0063, "Background Cs-137 Concentration in Soil." The reported values of Cs-137 were not enough to warrant radiological soil remediation.

During scoping surveys of adjacent SU 9528-0002 and 9528-0004, Co-60 and Cs-137 was identified in samples collected from soil piles and excavated areas found in these survey units. This data, as well as previously collected sample data from 9528-000, were used to develop a statistical summary of the eighteen (18) samples used for the survey design of 9528-0003 (see Table 1).Table 1 -Basis Statistical Quantities for Cesium-137 and Coblat-60 from the Characterization Survey Cesium-137 Cobalt-60 Parameter (pCilg)(pCi/g)

Revision I 4 Revis on 1.

SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD Interviews with HNP health physics personnel provided no information on the cause of the apparent soil disturbance in the area.A walkdown of the area was performed by FSS Engineers.

The FSS staff noted that the survey unit contained several locations with apparent soil disturbance.

At the time of FSS, the dose impact from groundwater contamination was not considered.

The classification basis shows that the expected residual radioactivity in the survey unit would be below the site remediation criteria and are consistent with procedural guidance, thereby sufficient to justify final Class 2 designation.

3. DATA QUALITY OBJECTIVES (DQO)The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9528-0003 did not exceed the release criteria specified in the LTP, was below the 10 mrem/yr Administrative Level Derived Concentration Guideline Level (DCGL), and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).FSS design and planning endorsed the use of the Data Quality Objective (DQO)process as described by the LTP, Procedure RPM 5.1-11, "Preparation of Final Statuts Survey Plan," and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM).

A summary of the main features of the DQO process are provided herein.The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis.

Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition.

The baseline condition is technically known as the null hypothesis.

Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection.

In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria.

Rejection of the null hypothesis would satisfy the release criteria objective of the FSS.The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern during the 9528-0003 FSS process. Additionally, to provide conservatism, the Base Case DCGLs for radionuclides in soil was reduced by 60% to establish the Administrative Level DCGL. As multiple radionuclides were assumed to be present, the "unity rule" or "sum of the fractions," described by Equation 5-32 of the LTP, was used to show compliance with the release criteria.Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were performed before issue and after the instrument had been Revision I 5s Revision 1 5 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD used. Control and accountability of survey instruments were maintained to assure the quality and prevent the loss of data.Laboratory DQOs and analysis results were reported as actual calculated results.Results reported as less than Minimum Detectable Concentration

(<MDC)would not be accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result and uncertainty of two standard deviations (2a), laboratory data qualifiers, units and the required and observed MDC (see Table 2).Table 2 -FSS DCGL Values and Required Minimum Detectable Concentrations Radionuclide Base Case Soil Administrative Level Required MDC DCGL (pCig() DCGL (pCi/g) 2) (pCig)H-3 4.12E+02 1.65E+02 1.65E+01 C-14 5.66E+00 2.26E+00 2.26E-01 Mn-54 1.74E+01 6.96E+00 6.96E-01 Fe-55 2.74E+04 1.IOE+04 l.1OE+03 Co-60 3.81 E+00 1.52E+00 1.52E-01 Ag-108m 7.14E+00 2.86E+00 2.86E-01 Ni-63 7.23E+02 2.89E+02 2.89E+01 Sr-90 1.55E+00 6.20E-01 6.20E-02 Nb-94 7.12E+00 2.85E+00 2.85E-01 Tc-99 1.26E+01 5.04E+00 5.04E-01 Cs-134 4.67E+00 1.87E+00 1.87E-01 Cs-137 7.91 E+00 3.16E+00 3.16E-01 Eu-152 1.O1E+01 4.04E+00 4.04E-01 Eu-154 9.29E+00 3.72E+00 3.72E-01 Eu-155 3.92E+02 1.57E+02 1.57E+01 Pu-238 2.96E+01 1.18E+01 1.18E+00 Pu-239/240 2.67E+01 1.07E+01 1.07E+00 Pu-241 8.70E+02 3.48E+02 3.48E+01 Am-241 2.58E+01 1.03E+01 1.03E+00 Cm-243/244 2.90E+01 1.16E+01 1.16E+00 (1) The Base Case DCGLs for soil are specified by the LTP in Chapter 6.(2) The Administrative Level DCGL is 40% of the Base Case DCGL.(3) The required MDC was 10% of the Administrative Level DCGL.4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. To assist the Final Status Survey Engineers (FSSE) when preparing survey plans for FSS, guidance is provided in Procedure RPM 5.1-11. By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP.Revision 1 6 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD The LTP specifies that scanning will be performed in a combination of systematic and judgmental measurement for a Class 2 land area and cover 10%to 100% of the area. The fraction of scanning coverage was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS. Based on conditions found during the area inspection tours, three (3) areas, totaling 1,028 m 2 in area or 10.28% of the SU surface area, were selected for scanning.

These locations were determined to have the highest potential for elevated activity based on process knowledge and previous sampling results. Scans were also prescribed for a one (1) meter radius around each random and biased Sample Measurement Location (SML).Eighteen (18) data points were used to determine the radiological concentration variability in this survey unit. The population data set included data from adjacent areas collected during scoping and characterization.

Radionuclide-specific analyses of soil samples collected from this survey unit and adjacent land areas with similar history and physical characteristics have identified only a few radionuclides, principally Cs-137 and Co-60 infrequently.

The data collected prior to FSS indicated that the remaining radionuclides listed in Table 2 would not be present in quantities greater than 5% of the applicable Base Case DCGL in this survey unit at the time of FSS. It was unlikely that the aggregate concentration of the remaining radionuclides would exceed 10%;therefore, only Cs-137 and Co-60 were used in the survey planning of SU 9528-0003. The use of the 5% and 10% rule is consistent with the development of surrogate ratio DCGLs as described in the LTP.Since multiple radionuclides were assumed to be present, the "unity rule" or"sum of the fractions" was used to demonstrate compliance with the release criteria.

Therefore, the Operational DCGL is considered to be "1." Surrogate DCGLs are not required for this survey unit because of the radionuclide specific analysis and radionuclide de-selection in accordance with the 5% and 10% rule.The Elevated Measurement Comparison (EMC) does not apply to this survey unit since discrete, elevated areas of contamination are not expected.The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

This approach was conservative since it included background Cs-137 as part of the sample set.The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Numnber of Surface Samples for FSS. " Survey design specified fifteen (15) surface soil samples for the Sign Test non-parametric statistical testing.For the FSS, four (4) biased soil SMLs were selected in areas indicating soil disturbance or at the discretion of the FSS Engineer.

In addition, four (4)Revision I 7 Revision 1 7 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD samples were collected to the depth of the limit of soil disturbance, approximately two (2) feet, in areas where construction activities had occurred.Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for Hard-to-Detect (HTD) analysis, two (2) soil samples or 13% were randomly selected for HTD radionuclide analysis by using the Microsoft Excel "RANDBETWEEN" function.

Each sample would be sent for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12,"Radionuclides Potentially Present at Haddam Neck Plant." The implementation of survey specific quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey," included the collection of one (1) soil sample for "split sample" analysis by the off site laboratory.

This location was selected randomly using the MicrosoftD Excel "RANDBETWEEN" function.

The number of quality control soil samples was determined to be 6% of fifteen (15) samples, rounded up to the next whole number.The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identi ing and Marking Surface Sample Locations for FSS." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 2 area.Sample location and scan areas were identified using AutoCAD-LtD a commercially available plotting software with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample and scan locations in the field. SMLs for the design are listed with the GPS coordinates in Table 3.Revision 1 8 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD Table 3 -Sample Measurement Locations (SML) with Associated GPS Coordinates.

The Lower Bound of the Gray Region (LBGR) was adjusted in accordance with Procedure RPM 5.1-11 to 0.87 to maintain the relative shift (A/a) in the range of 1 and 3. In a Class 2 survey unit the median concentration is expected to be well below the LBGR, in which case a Prospective Power Curve would be unnecessary and was not generated.

The mean concentrations for Co-60 and Cs-137 identified during the scoping and characterization indicate this assumption to be true.Table 4 provides a synopsis of the survey design.Revision I 9 Revision 1 9 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD Table 4 -Synopsis of the Survey Design Feature Design Criteria Basis 20 Based on AutoCAD and Survey Unit Size 10,000 m Visual Sample Plan I calculations Type I (a) and Type II (P)Number of Measurements 15 were 0.05; relative shift (A/a) set at 2 by procedure, the LBGR was 0.87.Grid Spacing 10.75 m.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0002-00104-000.

The WP&IR package included a detailed FSSP, job safety analysis, job planning checklist and related procedures for reference.

Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The"Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.Survey activities occurred July 12 through July 17, 2002.Seven (7) scan areas were marked out using GPS coordinates consistent with the Connecticut State Plane System and scanned for elevated readings (see Attachment 2 for Scan Area Results).

Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector.

The E-600 was operated in the rate-meter mode and used with audio response.

The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second.Using GPS coordinates, SMLs were identified and marked with a surveyor's flag for identification.

At each SML, a one (1) meter radius around the sample flag was scanned for elevated radiation levels.Fifteen (15) surface soil samples were collected in random locations and packaged in accordance with HNP Procedure RPM 5.1-3, "Collection of Surface and Subsurface Soil, Shoreline Sediment, Asphalt and Liquid samples Revision 1 10 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD for Scoping, Characterization and Final Status Survey," and FSS design.Samples were controlled, transported, stored, and transferred to the off site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Scoping, Characterization and Final Status Survey Samples. " Two (2) samples (004F and 0019F) were randomly selected for HTD radionuclide analysis.Four (4) biased samples were collected (016F, 017F, 018F and 019F) where construction activities had occurred or had potential to impacted local soils.With the exception of 019F, these samples were analyzed by gamma spectroscopy at the HNP.Four (4) soil samples (002FD, 004FD, 01OFD and 013FD) were taken to the depth of the limit of disturbance (2 feet) where construction activities had occurred in the survey unit. These samples were analyzed by gamma spectroscopy at the HNP.The implementation of survey specific quality control measures included the collection of sample OIOF for "split sample" analysis by the off site laboratory.

6. SURVEY RESULTS One elevated reading was identified during scanning the SML 005F. Scan Area I and 2 contained areas with elevated readings, which prompted the collection of investigation samples from these areas. The investigation results are discussed in Section 8 of this report. Table 5 provides an overview of the Scan Area survey.

The laboratory analyzed the fifteen (15)samples taken for non-parametric statistical testing, the associated duplicates and the biased samples using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDC. The results of gamma spectrometry analysis for a majority of the samples indicated Cs-137 at levels consistent with concentrations of Cs-137 found in soil at offsite locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063,"Background Cs-137 Concentration in Soil." The data shows that Co-60 was reported as less than 5% of the Administrative Level DCGLSOi on all samples collected.

Sample 9528-0003-005F was scanned during collection and identified as "elevated." Sample analysis did not indicate any anomalies requiring further investigation.

Six percent (6%) of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using United States Nuclear Regulatory Commission (USNRC)acceptance criteria specified in Inspection Procedure 84750 as detailed in Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey." There was acceptable agreement between field split results. The sample analysis vendor, STL-Richland, Richland, Washington, maintains quality control and quality assurance plans as part of normal operation.

REMEDIATION AND RESULTS Historically, no remediation was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Statis Survey," determined that remediation beyond that required to meet the release criteria to be unnecessary and that the remaining residual radioactivity in soil was ALARA.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN The change made from the LTP, prior to this FSS, was a decrease in the concentrations for the Base Case DCGLSOiS.

The LTP presents DCGLs that correspond to a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr. This survey unit was evaluated against Administrative Level DCGLs that correspond to 10 mrem/yr.Sample location 9528-0003-014F was moved eighteen (18) feet from the designated location due to dense overgrowth that prohibited work in the area.FSSP Addendum 1 and 2 were submitted to perform confirmatory sampling at several locations where scan measurements have exceeded the investigation level specified plan (SML 020F to 03 IF).Revision 1 14 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD FSSP Addendumi 3 was submitted to provide DCGLs as specified in Revision#1 to the LTP. The submitted revision to the LTP included changes to DCGL values for soil, some of which are slightly different than those provided in the FSSP. The decision statement and detection sensitivity are both dependent on the correct value for DCGL. These DCGLs and MDC values have been modified to meet a 10 mremlyr release criterion as shown in Table 2.11. DATA QUALITY ASSESSMENT (DQA)The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment," for completeness and consistency.

The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. All sample results were less than the release criteria.

Therefore, the Sign Test shows that the survey unit passes FSS.Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 3.The preliminary data review consisted of converting the data into units relative to the release criteria (i.e., pCi/g) and calculating basic statistical quantities (e.g., mean, median, standard deviation).

The FSS mean values for Cs-137 and Co-60 were well below those used for survey design; whereas, standard deviations were almost equal to the values used for design, thus representing expected variability.

This type of survey optimization was expected since data from previous surveys in the area were used to obtain survey-planning parameters.

The Cs-137 range of the data is about 3.5 standard deviations.

The difference between the mean and median was 24% of the standard deviation.

The histogram of the data indicates it is skewed positive.

Two (2) samples are displayed as "outliers" in this sample set, indicating that another distribution may exist. These outliers are near or below 10% of the Administrative DCGL value for Cs-137. Survey Unit 9528-0003 was excavated for construction in the past and the graphical presentation of the data may represent this event.The Co-60 range of the data is about 2.2 standard deviations.

The difference between the mean and median was 4.6% of the standard deviation.

The histogram of the data indicates it is slightly skewed positive.

All sample results are well below 10% of the Administrative Level DCGL value for Co-60. Survey Unit 9528-0003 was excavated for construction in the past and the graphical presentation of the data may represent this event.All data, assessments and graphical representations are provided in Attachment 2.Revision I 15 Revision 1 15 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD 12. ANOMALIES All data is considered valid including negative values, zeros, values reported below the MDC and values reported with uncertainties greater than two standard deviations (2a). Some radionuclides have been reported at low concentrations that are statistically significant at the 95% confidence level, but with a relatively high level of uncertainty.

Gamma spectroscopy results identified several radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

Cesium-134 and Am-241 were frequently identified in sample results. The offsite laboratory data qualifier unit shows that these radionuclides were analyzed for and the result was less than the MDC. These very low-level "detections" may be attributed to false positive noise at the lower limit of the measuring technique.

Two (2) samples were submitted to the offsite laboratory and analyzed for HTD radionuclides.

The analysis indicates that Sr-90 was the only identified radionuclide in the samples meeting the criteria for acceptance.

Typically, the levels and geographical locations of the Sr-90, along with Cs-137, found in the analysis are associated with weapons testing and atmospheric fallout. The amounts identified in the report suggest that this is the origin of the Sr-90 along with certain amounts of Cs-137. The Sr-90 value compares favorably with research conducted in other regional areas concerning fallout resultant from nuclear testing in the past as referenced in EPRI Technical Report 1003030,"Determining Background Radiation Levels in Support of Decommissioning Nuclear Power Plants. " Plutonium was detected in one (1) of the HTD samples but below the criteria for identification.

The likely source of Pu-239/240 is the release of plutonium from past atmospheric nuclear weapons testing and bum-up and vaporization of the United States SNAP 17A satellite in the atmosphere given the extremely low levels reported.These HTD radionuclides do not represent quantities that would increase the requisite number of samples for non-parametric statistical sampling or cause the survey unit to fail to meet the release criteria.

Sample analysis did not indicate any anomalies requiring further investigation.

The analytical data shows that all the identified HTD radionuclides were reported as a small fraction of the corresponding soil DCGL. Most radionuclides were reported at levels well below the required MDC. All were reported below the desired MDC, that is, less than 10% of the soil DCGL.During the survey of Scan Area 1, an outcropping of rock was identified as containing naturally occurring radioactive materials.

Initial survey with the Eberline E-600 using a SPA-3 sodium iodide detector gave a reading of 35,000 cpm. Geological occurrences of this type are discussed in the Health Physics Revision 1 16 SOUTHEAST MOUNTAIN SIDE SURVEY UNIT 9528-0003 RELEASE RECORD TSD CY-HP-0150, "Investigation of Rock Outcropping Exhibiting Elevated Activity.

" 13. CONCLUSION Survey Unit 9528-0003 has met the DQOs of the FSS. For this survey unit, the ALARA criteria for soils as specified in Section 4 of the LTP were achieved.Elevated Measurement Comparison and remediation was not required.The sample data passed the Sign Test. The null hypothesis was rejected.Evaluation of the data shows that none of the FSS design radionuclides or HTD soil concentration values exceeded the Operational DCGL or unity. No large anomalies were observed in the graphical representation of the data. The survey unit was properly designated as Class 2. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.This survey unit was evaluated for the potential impact by radioactive contamination in groundwater based on location, topography and current hydro-geologic sampling data as referenced in Health Physics TSD CY-HP-0193,"Assessment of Existing Groundwater Dose for Phase II Release Areas of the Final Status Survey Report. " For SU 9528-0003, the highest existing groundwater dose within the zone of influence is the January 2002 Sr-90 sample results for Supply Well B (1.02 pCi/I). Tritium (H-3) was not detected in the sample and therefore no dose due to H-3 need be included.

Using the LTP 25 mrem/yr DCGL for Sr-90 of 251 pCi/l for Sr-90, the calculated dose would be 0.102 mrem/yr. As this is approximately 0.4% of the 25 mrem/yr DCGL, consistent with the LTP this dose is not required to be included in showing compliance with site unrestricted release criteria.14.

The approach, "Law of Propagation of Errors", involves the identification of all variables in an analytical method which are used to derive a result. These variables are related to the analytical result (R) by some functional relationship, R = constants

• f(xyz-,...).

The components (x~y,z) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (u) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the components, such as sample homogeneity, are combined with the component uncertainty as the square raat orthe sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (u,) multiplied by the coverage factor (1,2, or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included In the standard deviation.

Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in "NIST Technical Note 1297, 1994 Edition. The approach, 'Law of Propagation of Errors", involves the identification of all variables in an analytical method which are used to derive a result These variables are related to the analytical result (R) by some functional relationship, R = constants

• f(x,y.z...).

The components (x,y,z) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (ud) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties arm categorized as type A. evaluated by statistical methods, or type B. evaluated by other means. Uncertainties not Included in the components.

such as sample homogeneity, are combined with the component uncertainty as the square root of the sun-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (u.j multiplied by thc coverage factor (1,2, or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (Slvn), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included in the standard deviation.
