SURVEY UNIT DESCRIPTION Survey Unit (SU) 9537-0000, (Permitted Landfill) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 850 m 2 (0.21 acres) of open land area located approximately 0.85 miles from the center of the Haddam Neck Plant (HNP) Containment Building (see Attachment 1-Figure 1). Survey Unit 9537-0000 is at the south end of an excavated sandpit and west of the former pistol range (SU 9536-0000).

The landfill was constructed as a north-south trench approximately 120 feet long by 50 feet wide. The area topography was altered and graded to what was assumed to be the original grade. The area slopes upward to a wooded area (SU 9523-0000) and was cleared of all scrub growth and reseeded to prevent erosion.The reference coordinates associated with the Permitted Landfill are E041 through E047 by S129 through S134 (refer to License Termination Plan Section 5.4.4). 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 soil and spoils were transported to the general vicinity of this area as early as 1976. Specific details relevant to date or time period and exact location of placement were not available.

Excavation and trenching prior to FSS was performed in this survey unit for the purposes of removing materials and spoils (e.g., concrete, asphalt, metal, etc.).Radiological surveys for contamination did not identify radioactive material on these items. The Permitted Landfill area was staked out and measured during the 1997 scoping survey. The current area of the Permitted Landfill was assumed to be 850 m 2 based on the staked positions.

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 9537-0000 as Class 2 in August 2001.The "Classification Basis Summary" conducted for SU 9523-0000 consisted of: a) A review of the IOCFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Personal interviews, e) Visual inspections and a "walk down." Revision I 3 Revision 1 3 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD A review of the IOCFR50.75 (g) (1) database report identifies no events that might have impacted this survey unit. The only listing was a reference to scoping survey data. These data were included in the IOCFR50.75 (g) (1)database for historical purposes and to facilitate final status survey planning for this survey area.A review of the "Initial and Supplemental Characterization Reports " as well as the previous "Classification Basis Summaries" indicates that the area was established for the disposal of bulky waste on Connecticut Yankee property.The permit limited the use of the disposal area to include only bulky wastes such as scrap metals, wood, rubble, land-clearing wastes, and demolition wastes. Furthermore, the permit bars the deposition of garbage, sludge, putrescible material, and radioactive material in the area. The Permitted Landfill is thought to have never been used for the purposes of bulky waste disposal.

The origin of the materials excavated there and timeframe of placement is unknown.A Survey Sampling Work Plan (SSWP N2. BCY-SSWP-03-08-001) was developed and implemented during September 2003 to obtain the necessary data of sufficient data quality for FSS planning purposes.

Thirty-five (35) samples were obtained through biased sampling over a simple grid design approximating a triangular pattern. The samples were analyzed at HNP by gamma spectroscopy.

The only radionuclide identified in the samples was Cs-137, which was identified just once and at very low levels. The concentrations of Cs-137 found in the soil were below those concentrations determined from off-site locations as documented by Health Physics Technical Support Document (TSD) BCY-HP-0063, "Background Cs-137 Concentration in Soilr (see Table 1).Table 1 -Basis Statistical Quantities for Cesium-137 from the Characterization Survey Cesium-137 Parameter (pCilg)Minimum Value: 0.0001 Maximum Value: 0.1290 Mean: 0.0389 Median: 0.0370 Standard Deviation:

0.0252 Haddam Neck Plant staff conducted personnel interviews during the historical site assessment to ascertain the history of the Permitted Landfill.

Individuals responding to the questionnaire stated that spoils originating from construction activities such as new building construction, addition to existing buildings and general site maintenance and repairs were brought to the shooting range landfill.Revision I 4 Revision 1 4 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD FSS Engineers performed a walkdowvn of the area. The FSS staff indicated that the area is an open space with little or no obstructions.

Materials and spoils have been removed from the area. Most of the area is sand based, although rock masses have been identified during trenching.

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

The characterization data would have been sufficient to justify final designation as Class 3. Nevertheless, the survey design maintained the initial designation as a Class 2 to be prudent.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 9537-0000 did not exceed the release criteria specified in the License Termination Plan (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 Status Survey Plan," and the "Miulti-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.Characterization efforts in nearby areas have included analysis for Hard-to-Detect (HTD) radionuclides.

In some cases, HTD radionuclides were reported above the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty-2a).

Comparing reported maximum concentrations to the soil DCGLs shows no impact on FSS design. This conclusion was based on the very low percentage of the HTD radionuclide to the soil DCGL.The DQO process determined that Cs-137 would be the radionuclide of concern during the 9537-0000 FSS process. Additionally, to provide conservatism, the Base Case DCGLs for radionuclides in soil was reduced by 60% to establish the Administrative Level DCGL.Revision I 5s Revision I 5

• PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD 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 afler the instrument had been 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 (pCI/g) DCGL (pCilg) (2) (pCi/g) (3)H-3 4.12E+02 1.65E+02 1.65E+OI C-14 5.66E+00 2.26E+00 2.26E-O01 Mn-54 1.74E+01 6.96E+00 6.96E-O 1 Fe-55 2.74E+04 1.I1OE+04 1.11OE+03 Co-60 3.81 E+OO 1.52E+0O 1.52E-O1 Ag-108im 7.14E+00 2.86E+00 2.86E-O1 Ni-63 7.23E+02 2.89E+02 2.89E+O1 Sr-90 1.551E+OO 6.20E-01 6.20E-02 Nb-94 7.12E+00 2.85E+00 2.85E-O1 Tc-99 1.26E+01 5.04E+00 5.04E-O1 Cs-134 4.67E+00 1.87E+00 1.87E-O1 Cs-137 7.91 E+OO 3.16E+00 3.16E-O1 Eu-152 1.OIE+OI 4.04E+00 4.04E-O1 Eu-154 9.29E+00 3.72E+00 3.72E-O1 Eu-155 3.92E+02 1.57E+02 1.57E+O1 Pu-238 2.96E+01 1.18E+O1 1.18E+OO Pu-239/240 2.67E+01 1.07E+01 1.07E+OO Pu-241 8.70E+02 3.48E+02 3.48E+O1 Am-241 2.58E+01 1.03E+01 1.03E+OO Cm-243/244 2.90E+01 1.16E+01 1.1 6E+OO (1) The Base Case DCGLs for soil are specified by the LUP 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.Revision I 6 Revision 1 6 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD 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 FSS Engineers 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.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. Elevated areas of residual radioactivity were not considered likely based on characterization data. Nevertheless, given the historical use of the landfill the decision was made to scan 100% of the area.The scan design consisted of twenty-nine (29) evenly spaced strips oriented north to south. Scans were also prescribed for a one (1) meter radius around each random and biased Sample Measurement Location (SML).Thirty-five (35) data points were used to determine the radiological concentration variability in this survey unit. The samples were collected through biased sampling over a simple grid design.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. 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 was used in the survey planning of SU 9537-0000.

The use of the 5% and 10% rule is consistent with the development of surrogate ratio DCGLs as described in the LTP.The DQO process determined that Cs-137 would be the radionuclide of concern during the 9537-0000 FSS process. The Operational DCGL of 3.16 pCi/g for Cs-137 was used to demonstrate compliance with the release criteria.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.Revision 1 7 Revision I 7 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for FSS." Survey design specified fifteen (15) surface soil samples for the Sign Test non-parametric statistical testing.Four (4) Judgmental or biased depth samples were selected in locations randomly using the Microsoft Excel "RANDBETWEEN" functions.

The collection of the "at depth" samples was to account for soil disturbance as a result of material and spoils removal from the area prior to FSS. In addition, the Permitted Landfill was originally constructed as a north-south trench approximately 120 feet long by 50 feet wide to a depth of 5 feet. The four (4)samples were to be collected to the depth of the original grade or refusal, homogenized and analyzed by gamma spectroscopy.

The number of judgmental samples represented 25% percent of the number of samples that would be used for non-parametric statistical testing.Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for 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 two (2) soil sample for "split sample" analysis by the off site laboratory.

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

The number of quality control soil samples was determined to be 13% 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, "Identifying, and Marking Surface Samnple 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-Lt 0 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. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Revision I 8 Revision 1 8 PERMITTED LANDFILL SURVEY UNIT 9537-0000 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 0.98 of the Administrative Level DCGL to maintain the relative shift (A/a) in the range of I and 3. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.Table 4 provides a synopsis of the survey design.Revision I 9 Revision 1 9 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD Table 4 -Synopsis of the Survey Design Feature Design Criteria Basis Survey Unit Land Area 850 m GPS measurements of area Type I and Type 2 were 0.05, sigma was 0.0252, the Number of Measurements 15 LBGR was adjusted to 0.98 (3.11) to maintain Relative Shift in the range of 1 and 3 Grid Spacing 8.09 m Based on triangular grid Interval Spacing 7.01 m Based on triangular grid DCGL3.16 pCi/g Operational DCGL applied DCGL _Cs-137 to field data (1)Scan Survey Area 100% Based on historical use of Coverage landfill area Scan Investigation Level Detectable over Based on achieving the background Administrative Level DCGL (I) The Operational DCGL was based on achieving an administrative level that was 40%0 of the soil DCGL and assuming no impact from radioactive contamination in groundwater or from buried concrete debris.5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0000-00134-000.

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 November 11 through November 14, 2003.The 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 for Scoping, Characterization, and Final Statuts Survey," and FSS design.Samples were controlled, transported, stored, and transferred to the off site Revision I 10 Revision I 10 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of C'ustody for Scoping, Characterization and Final Status Survey Samples. " Two (2) samples (OOIF and 0014F) were randomly selected for HTD radionuclide analysis.Four (4) biased soil samples (005F02, 007F02, 01 1F02, and 014F02) were taken to the depth of the limit of disturbance 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 samples 002F and 006F for "split sample" analysis by the off site laboratory.

6. SURVEY RESULTS No elevated readings were identified during scanning the SMLs. Five (5) Scan Areas contained areas with elevated readings, which prompted the collection of investigation samples from these locations.

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

Cesium-137 was identified in five (5) of the fifteen(15) samples (33%). 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.

The data shows that Co-60 was reported as less than 2% of the Administrative Level DCGL on all samples collected.

Sample analysis did not indicate any anomalies requiring further investigation.

Thirteen percent (13%) of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP 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.

Refer to Attachment 2 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS Seven (7) localized areas were identified above the investigation level during the scan area survey. Soil samples were collected at each of the locations and analyzed at the offsite laboratory using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDC. Review of the sample analysis results did not identify elevated results. None of the samples exceeded 5% of the Administrative Level DCGL for Cs-137 and Co-60. No further investigation was required (see Table 9).Revision I 14 Revision I 14 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD Trahla OTnvyctfofmnn si"mrpc 'nrlagtpf]

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 Status 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.The required MDCs for Sr-90 and C-14 could not be reasonably achieved.

The data quality objectives recognized that certain analytical methods might not meet MDC requirements (e.g., C-14 in soil). The MDC were set at 4% of the soil DCGL to be as far below the DCGL as practical.

In accordance with the LTP, a value at 10% of the soil DCGL would have been the desired level of sensitivity.

Review of the data shows C-14 and Sr-90 MDCs to be well below the desired level of sensitivity specified by Section 5.5 of the LTP (i.e., <10% of the applicable soil DCGL) and are therefore acceptable.

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.Revision 1 15 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD 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 2.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).

Cesium-137 sample standard deviation was slightly less than the value used for the survey design. This indicates that a sufficient number of samples were collected to achieve the desired power. The range of the data, about 3.2 standard deviations, was not unusually large. The difference between the mean and median was 33% of the standard deviation.

The difference is enough to indicate skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The data follows a relatively normal distribution about the mean value with some positive skewness.All data, assessments, and graphical representations are provided in Attachment 2.12. 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 standard deviations uncertainty-2a).

Cesium-134 was frequently identified in sample results. Other radionuclides, such as Am-241, Mn-54, and Eu-155 were identified sporadically.

The offsite laboratory data qualifier unit shows that these radionuclides were analyzed for, however, either the result was less than the MDC or the gamma software did not identify the radionuclide.

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.

Hard-to-detect analyses results identified several radionuclides meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty-2u).

Iron-55 and H-3 (tritium) was identified in both samples (100%). Strontium-90, and Tc-99 was identified in SML 001F, Pu-241 in SML 014F. In almost all cases, the magnitude of the analytical bias was less than sample required MDC. By comparison, reported MDCs were less than the required MDCs by factors of two (2) up to 550 (with the exception of Revision I 16 Revision 1 16 PERMITTED LANDFILL SURVEY UNIT 9537-0000 RELEASE RECORD Sr-90 as described in a Section 10). These very low-level "detections" may be attributed to false positive noise at the lower limit of the measuring technique.

The analysis indicates that Sr-90 was identified in one (1) of the samples.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 MDC.The likely source of Pu-241 is the release of plutonium from past atmospheric nuclear weapons testing and burn-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 most of the identified HTD radionuclides were reported as a small fraction of the corresponding soil DCGL. Most radionuclides were reported at levels near or below the required MDC.13. CONCLUSION Survey Unit 9537-0000 has met the DQOs of the FSS. For this survey unit, the ALARA criteria for soils as specified in Chapter 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. Although several localized spots exceeded the investigation levels there were no elevated areas based on sample measurements results. 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 is not considered impacted 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 Groundwvater Dose for Phase II Release Areas of the Final Status Survey Report.

The approach.

CLaw 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 cvaluatcd to determine their contribution to the overall method uncertainty.

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

such as sample homogencity, are combined with the component uncertainty as the square root of the sum-of-thc-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.yz...).

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

The individual component uncertainties (tu) 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 root of the sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (uJ 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.

The derivation of the general 'Law of Propagation of Errors' equations and specific example are available on request.hland 6 Action Lev Batch Bias COC No Count Error (#s)Report Definitions An agreed upon activity level Uised to trigger some action when the final result is greater than or equal to the Action Level.
