SURVEY UNIT DESCRIPTJDN Survey Unit 9521-0000 (Southeast Pond) is designated as Final Status Survey (FSS) Class 3 and consists of 25,456 m 2 (6.3 acres) of uninhabited open land located approximately 0.24 miles from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1, Figure 1).The area topography varies from flat areas overgrown with brush to rocky outcroppings to wooded sloping hills with steep grades. A small pond is contained in the interior of the survey unit. Some low-lying areas near the pond are marshy. Old stone walls presumably used to mark former property lines are evident along Cove Road and the northern edge of the pond. There are no structures within the survey unit. This survey unit is bounded on the north by Survey Area 9526; by Cove Road on the east; by the Discharge Canal on the south; and by a security fence and Survey Area 9522 on the west.The reference coordinates associated with this survey unit are E010 through E020 by S076 through S092 (refer to License Termination Plan (LTP) 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).There are no known events potentially impacting this survey unit. The historical files indicate that, in the past, the public was granted access to the Canal Road area for recreational purposes (e.g. fishing).

Typical debris and litter (soda bottles, fishing line, etc.) were seen along the Canal Road during an area inspection prior to FSS. The origin of the litter and timeframe could not be determined with any certainty.

From time to time, 55-gallon drums were used for trash containers along the Canal Road to collect and control litter.Work activities to support the Independent Spent Fuel Storage Installation (ISFSI) construction have occurred in this survey unit, especially on and along the Canal Road. These activities included tree and stump removal, silt fence installation, soil removal and grading. The Canal Road is now more commonly referred to as the ISFSI Road.In Section 5.4.7.1 of the LTP, Equation 5-1 expresses the total dose contribution from three (3) components; soil contribution, existing groundwater contribution and future groundwater contribution.

The survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-1. This survey unit is considered impacted by existing groundwater radioactive contamination as the survey unit is within the capture zone perimeter for an affected monitoring well. The dose contribution from the existing groundwater contamination will be addressed later and will be included to show compliance with site unrestricted release criteria as required by the LTP. This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area. The Revision 0 3 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification. " The historical information, scoping analyses and characterization results provided sufficient data to designate Survey Unit 9521-0000 as Class 3 in June 2002.The "Classification Basis Summary" conducted for this survey unit consisted of: a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "initial Characterization Report" and the "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walkdown." A review of the 10CFR50.75 (g) (1) database report identifies five (5)documents associated with or relating to this survey area.a) Adverse Condition Report (ACR) 97-0716 indicated that tritium was identified in a liquid sample taken at a discharge point in an adjacent survey area (Survey Area 9522).b) Condition Report (CR) 02-0185 tells of a soil sample containing low-level Co-60. The soil sample was collected for characterization to support FSS planning.c) Condition Report (CR) 03-0337 is related to failure to maintain isolation and control. Standing water was being pumped for several weeks from an adjacent un-surveyed Class I and Class 2 survey area (9522) located within the Industrial Area. A re-survey of the area found no negative change in the radiological status.d) Condition Report (CR) 04-0205 is related to failure to maintain isolation and control. There was a concern that dredging operations in an adjacent un-surveyed Class 2 survey unit (Discharge Canal) could have impacted the area. A re-survey of the area found no negative change in the radiological status.e) Memo ISC 05-045: Periodic surveillance following final status survey.Surveillance is required periodically by the LTP to ensure the radiological condition does not significantly change from the FSS results. The memo documents no negative change in the radiological status.Revision 0 4 SOUTHEAST POND SURVEY UNIT 952 1-0000 RELEASE RECORD A review of the "Initial and Supplemental Characterization Reports " as well as the previous "Classification Basis Summaries" provided no additional information pertinent to classification.

A characterization survey plan was initiated and executed by Site Closure personnel in April 2002 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). Radiological results from the recent surveys indicated that plant related radioactive materials in soil (e.g., Co-60) might be present. No areas of elevated radioactivity were identified in the survey unit.Ten (10) samples were taken initially in accordance with the plan. An additional five (5) investigatory samples were taken near the pond to confirm the identification of plant-related radioactivity Co-60. In addition, a water sample and two (2) sediment samples were collected from the edges of the pond. All samples were analyzed on-site. The concentrations of Cs-137 found in the soil were for the most part consistent with those concentrations in wooded areas determined from off-site locations as documented by Health Physics Technical Support Document (TSD) BCY-HP-0063, "Background Cs-137 Concentration in Soil." Cesium-137 was identified in the sediment samples but was not detected in the liquid sample. The values for Cs-137 and Co-60 are provided in Table 1.Table 1 -Basic Statistical Quantities for Cesium-137 and Cobalt-60 from the Characterization Surve Parameter Cs-137 (pCi/g) Co-60 (pCi/g)Minimum Value: 4.3 1E-02 2.71E-03 Maximum Value: 5.37E-01 1.1 IE-01 Mean: 2.20E-01 1.91E-02 Median: 1.63E-01 1.1 8E-02 Standard Deviation:

1.43E-01 2.68E-02 The FSS Engineer performed a visual inspection and walkdown during June 2002 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

Assessment of the groundwater impact is discussed in Section 1 and Section 13.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 the final designation as Class 3.3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning is based on the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "Preparation of Final Status Survey Plan, " and the "Multi-Agency Radiation Survey and Site Investigation Revision 0 5s Revision 0 5 SOUTHEAST POND SURVEY UNIT 952 1-0000 RELEASE RECORD 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. Probabilistic sampling is a preferred method to select a sample so that each item in the population being studied has a known likelihood of being included in the sample. Probabilistic sampling might include simple random sampling where every sample has the same chance of being included, or systematic random sampling where samples are arranged in some order and a random starting point is selected.The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in this survey unit did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity.

This is done through the development of Derived Concentration Guideline Values (DCGLs). The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations.

Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soil (called Base Case Soil DCGL), existing groundwater radioactivity and additional future groundwater radioactivity from building basements and footings.A reduction to the Base Case Soil DCGLs provided in Chapter 6 of the LTP must be performed to ensure compliance with the release criteria of twenty-five millirem (25 mrem) in a year Total Effective Dose Equivalent (TEDE) when all three pathways (soil, existing groundwater and future groundwater) are potentially present. Chapter 5 of the LTP shows a compliance formula, Equation 5-1, for including the total dose from the three media. The reduced DCGL is called the Operational DCGL whose relationship to the Base Case Soil DCGL is shown by Equation 5-3 of the LTP. The Base Case Soil DCGL for Cs-137 and the DCGLs for all the other radionuclides potentially present in soil were administratively reduced by about 60% to ensure compliance with the 25 mrem in a year TEDE criterion (Table 2).Revision 0 6 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD Table 2 -Radionuclide Specific Base Case Soil DCGL, Operational DCGLs and Required Minimum Detectable Concentrations Radionuclide Base Case Soil Operational DCGL Required MDC DCGL (pCi/g)t 1) (pCi/g) ) (pCi/g)(3)

Fifteen (15) soil samples were collected and analyzed during characterization as discussed in Section 2.The samples were collected through biased sampling over a simple grid design.Characterization did not include analyses for Hard to Detect (HTD)radionuclides as data from previous survey and sampling in adjacent areas did not identify HTDs in significant quantities (the H-3 identified in Survey Area 9522 would have been less than 4% of the Base Case Groundwater DCGL provided in Table 6-2 of the LTP. Cesium-137 and Co-60 were found to be the predominate radionuclides of concern in soil. The mean and variability of Cs-137 and Co-60 in soil in this survey unit was determined during characterization.

The potential for plant-related radionuclides in the pond water, including H-3 and Sr-90, due to the runoff from Survey Area 9522 and the Industrial Area was Revision 0 7 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD considered during the DQO process and as a result these radionuclides were included in the sample design. Samples of pond water were to be collected and analyzed by gamma spectroscopy and for H-3 and Sr-90.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 to be performed before issue and after the instrument had been used. Control and accountability of survey instruments was to be maintained to assure the quality and prevent the loss of data.Laboratory DQOs and analysis results were to be reported as actual calculated results. Results reported as less than Minimum Detectable Concentration

(<MDC) would not be accepted for FSS. Sample report summaries were to include unique sample identification, analytical method, radionuclide, result, and uncertainty of two standard deviations, laboratory data qualifiers, units, and the required and observed MDC.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,"Preparation of Final Status Survey Plans". By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP. The FSSP uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.Fifteen (15) data points from characterization were used to determine concentration variability.

The samples were collected through biased sampling over a simple grid design. The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern for soil in this survey unit (refer to Section 3). The sum of fractions or unity rule will be used with the individual Operational DCGLs because multiple radionuclides (Cs-137 and Co-60) are considered in the survey design. Other radionuclides identified during FSS would be evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit because of process knowledge from FSS of nearby adjacent areas and via screening under LTP Section 5.4.7.2. Radionuclide screening or de-selection is a process where an individual radionuclide or aggregate may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since discrete, elevated areas of contamination were not expected.Revision 0 8 Revision 0 8 SOUTHEAST POND SURVEY UNIT 952 1-0000 RELEASE RECORD 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 Number of Surface Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.9 to maintain the relative shift (A/cy) 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. Survey design specified fifteen (15) surface soil samples for non-parametric statistical testing.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 Sample Locations for Final Status Survey." 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 3 area.Sample locations were identified using AutoCAD-Lt, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9521-0000-OO1F 235918.51 669762.05 9521-0000-002F 236362.48 669670.19 9521-0000-003F 236045.98 669505.63 9521-0000-004F 236443.11 669657.91 9521 -0000-005F 236007.70 669604.04 9521-0000-006F 236454.54 669615.97 9521 -0000-007F 236276.60 669618.82 9521-0000-008F 235966.26 669532.84 9521-0000-009F 236286.98 669557.55 9521 -0000-OlOF 236383.36 669645.07 Revision 0 9 SOUTHEAST POND SURVEY UNIT 952 1-0000 RELEASE RECORD Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9521-0000-01 iF 236165.95 669871.24 9521-0000-012F 235930.73 669574.78 9521-0000-013F 236415.59 669452.43 9521-0000-014F 236249.53 669634.82 9521-0000-015F 236046.15 669601.52 There were to be seven (7) judgmental samples total for soil and pond water sampling.

The four (4) soil samples were determined based on professional judgment and observation during characterization and walkdowns to determine areas having the potential for residual radioactivity (e.g., runoff and collection, area disturbance).

The three (3) pond water samples would be from the shoreline of the pond at the discretion of the FSS Engineer.

The number of judgmental samples represented about 50% 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, at least two (2) soil samples or 13% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel"RANDBETWEEN" function.

Each sample would be sent off-site 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 samples for "split sample" analysis by the off-site laboratory.

These locations were selected randomly using the Microsoft Excel "RANDBETWEEN" function.

The number of quality control soil samples was determined to be 5% of fifteen (15) samples, rounded up to the next whole number.The LTP specifies that scanning will be performed in judgmental measurements for a Class 3 land area and cover a selected amount 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. The DQOs designated five (5) judgmental or biased scan areas for this survey unit. Scans were also prescribed for a one (1)meter radius around each random and biased sample measurement location.For this Class 3 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8,"Investigation Levels." Table 4 provides a synopsis of the survey design.Revision 0 10 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD Table 4- Synopsis of the Survey Design Feature Design Criteria Basis Survey Unit Land Area 25,456 m 2 Based on AutoCAD-Lt and Visual Sample Plan calculations Type I and Type 2 errors were 0.05, sigma was 0.048, the LBGR was adjusted to 0.9 to maintain Relative Shift in the range of I and 3, Relative Shift was 2 Grid Spacing Random and Appropriate design for Class 3 random start __ _ _ _ _ _ _ _ _ _ _ _ _Interval Spacing Not Applicable Not appropriate for Class 3 Operational DCGL 3.16 pCi/g Cs-137 Administratively set to achieve 1.52 pCi/g Co-60 10 mrem in a year TEDE Judgmental scanning coverage Scan Survey Area 564 m 2 for Class 3 area based on Coverage likelihood of finding elevated areas Scan Investigation Level Detectable over Based on achieving the background Operational DCGL 5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0000-00105-000.

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 June 25, 2002 through July 10, 2002.The five (5) scan areas were marked out 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, sample measurement locations were identified and marked with a surveyor's flag for identification.

At each sample measurement location, a one (1) meter radius around the sample flag was scanned for elevated radiation levels.Fifteen (15) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Revision 0 I1I SOUTHEAST POND SURVEY UNIT 9521 -0000 RELEASE RECORD Media for 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 Final Status Survey Samples. " Four (4) soil samples (9521-0000-008F, 9521-0000-009F, 9521-0000-013F and 9521-0000-015F) were randomly selected for HTD radionuclide analysis by the off-site laboratory.

Four (4) biased soil samples (9521-0000-016FM, 9521-0000-017FM, 9521-0000-018FM and 9521-0000-019FM) were collected and analyzed using gamma spectroscopy by the on-site laboratory.

The "FM" designation was used to distinguish between on-site and off-site analyses; where "FM" means soil collected and analyzed on-site in a one liter (I L) marinelli container.

Three (3) biased pond water samples (9521-0000-020F, 9521-0000-021F and 9521-0000-022F) were collected from the pond and analyzed by the off-site laboratory using gamma spectroscopy and selected HTD analyses (i.e., for Sr-90 and H-3).The implementation of survey specific quality control measures included the collection of sample 9521-0000-004F for "split sample" analysis by the off-site laboratory.

-STL Richland, Richland, Washington.

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

All but one (1) radionuclide could be deselected or excluded using the 5% and 10%rule described in Section 4. The exception was Cs-134 which was reported in several samples. Further explanation of Cs- 134 will be provided in Section 10.Revision 0 13 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD Cesium-137 was identified in fourteen (14) of the fifteen (15) samples. Cobalt-60 was identified in six (6) of the fifteen (15) samples and Cs-134 was identified in twelve (12) of the fifteen (15) samples. The mean of the results of gamma spectrometry analysis for each ofthe samples indicated Cs-137 at levels slightly lower than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

Sample analysis did not indicate any anomalies requiring further investigation.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC with the exception of Sr-90. However, the DQOs recognize that for some HTD analyses, the radionuclides may not meet MDC requirements due to analytic method (e.g., Carbon-14 in soil). In these cases, comparison to a higher value (i.e., 50% of the DCGL) is acceptable and consistent with the LTP. Table 8 lists the results for those radionuclides meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty) in more than one sample. All but one (1) radionuclide could be deselected or excluded using the 5% and 10% rule described in Section 4. The exception was Sr-90 which was reported in concentrations greater than 5% in two of the four Revision 0 14 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD samples.

Gamma spectroscopy analysis was performed on the four (4) soil samples by the on-site laboratory to the required MDC. Off-site analysis of the water samples included gamma spectroscopy and analysis for H-3 and Sr-90. None of the samples exceeded 10% of the Operational DCGL.

Five percent (5%) of the samples were selected for analysis, which meets 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, Severn Trent Laboratories

-STL Richland, Richland, Washington, maintained 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 Three (3) localized areas were found to verifiably exceed their investigation level during the scan area survey. A sample was collected from each location.The samples were analyzed on-site using gamma spectroscopy.

The analyses reported Cs-137 as shown in Table 10.Final status survey soil sample 9521-0000-OlOF was 65% of the Operational DCGL which exceeded the investigation level specified by the DQOs. A sample was collected at that location and was designated 9521-000-026F.

The confirmatory sample was analyzed by the off-site laboratory using gamma spectroscopy.

A summary of the sample results is provided in Table 10. No further investigations were required Table 10- Confirmatory Sample Results (1) Cs-137 Co-60 Fraction of the SampleNumber pCi/g pCilg Operational DCGL (2)9521 -0000-023FM 1.23E-01 1.95E-02 0.052 9521-0000-024FM 1.02E-01 9.37E-03 0.038 9521-0000-025FM 1.43E-01 9.49E-03 0.097 9521-0000-026F 1.53E-00 9.74E-03 0.491 (1) The "FM" designation was used to distinguish between on-site and off-site analyses;where "FM" means soil collected and analyzed on-site in a I L marinelli container; an where" means soil collected and analyzed off-site.(2) The Operational DCGLs are 3.16 pCi/g for Cs-137 and 1.52 pCi/g for Co-60 used in conjunction with the unity rule 9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 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.Revision 0 16 Revision 0 16 SOUTHEAST POND SURVEY UNIT 9521-0000 RELEASE RECORD 10. CHANGES FROM THE FINAL STATUS SURVEY PLAN Several radionuclides (i.e., Cs-134 and Sr-90) were reported in concentrations exceeding the 5% and 10% rule for de-selection.

Therefore, the individual Operational DCGLs for these radionuclides were included into sample design to demonstrate compliance with the unity rule and ensure adequate survey design in accordance with the DQOs. The result of the COMPASS computer run showed adequate power for the revised survey design. The revised survey design maintained the original fifteen (15) surface soil samples for non-parametric statistical testing.Survey design required HTD analysis for three (3) pond water samples;however, the off-site laboratory processed and analyzed only two (2) of the samples. A review of the pond water sample results in Table 9b indicate that the third sample would be unnecessary given the low concentrations reported for the radionuclides of interest (Sr-90 and H-3).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. 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 calculating basic statistical quantities (e.g., mean, median, standard deviation).

The range of the data, about 3.6 standard deviations, was not unusually large.The difference between the mean and median was 15% 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 frequency plot shows slight positive skewness as confirmed by the calculated skew of 0.3 and some bimodality (two peaks) probably due to the differences in terrain or soil type.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES No anomalies were noted.Revision 0 17 SOUTHEAST POND SURVEY UNIT 952 1-0000 RELEASE RECORD 13. CONCLUSION Survey Unit 9521-0000 has met the final DQOs of the FSS. 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.Graphical representation of data indicates significant positive skewness as that is probably due to the differences in terrain and the collection of runoff. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.

The survey unit was properly designated as Class 3.As discussed in Section 1, the survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-1. This survey unit is considered impacted by existing groundwater radioactive contamination as the survey unit is within the capture zone perimeter for an affected monitoring well. The dose contribution from the existing groundwater contamination will be addressed later and will be included to show compliance with site unrestricted release criteria as required by the LTP. This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area. The dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.14.

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(xy,z,...).

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

The individual component uncertainties (A4) 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 (ut) 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 (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.

The derivation of the general "Law of Propagation of Errors" equations and specific example are available on request.STL Richland rptGcnerollnro v3.72 STL RICHLAND 4 Report Definitions Action Lev An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action Level.

Summary Report I. Introduction On October 24, 2002, four soil samples were received at STL Richland (STLR) for radiochemical analysis on one chain-of-custody (00022). Upon receipt, the samples were assigned to Lot Number J2J240255 with the laboratory ID numbers to correspond with the Bechtel Corp. (BCT) specific IDs as listed on the cover page.II. Analytical Results/Methodology The analytical results for this report are presented by laboratory sample ID. Each set of data includes sample identification information; analytical results and the appropriate associated statistical errors.The requested analyses are: Alpha Spectroscopy Americium/Curium-isotopic by method RICH-RC-5080 Plutonium-238, 239/240 by method RICH-RC-5010 Gas Proportional Counting Strontium-90 by method RICH-RC-5006 Gamma Spectroscopy Gamma Spec by method RICH-RC-5017 Liquid Scintillation Counting Tritium by method RICH-RC-5037 Technetium-99 by method RICH-RC-5065 STL Rtchland is a part o1 Sever Trent Laboratories, Inc.STL RICHLAND 3 Bechtel Corporation December 31, 2002 Page 2 Carbon-14 by method RICH-RC-5022 Iron-55 by method RICH-RC-5074 Nickel-63 by method RICH-RC-5069 Plutonium-241 by method RICH-RC-5010

m. Quality Control The analytical results for each analysis performed under SDG 21408 includes a minimum of one Laboratory Control Sample (LCS) and one method (reagent) blank and one duplicate sample analysis.

Any exceptions have been noted in the "Comments" section.QC and sample results are reported in the same units.IV. Comments Alpha Spectroscopy Americium/Curium-isotopic by method RICH-RC-5080:

All results are below the CRDL and/or below the MDC. Except as noted, the LCS, sample duplicate, batch blank and sample results are within contractual requirements.

Plutonium-238.

239/240 by method RICH-RC-50 10: All results are below the CRDL and/or below the MDC. The LCS, sample duplicate, batch blank and sample results are within contractual requirements.

Gas Proportional Counting Strontium-90 by method RICH-RC-5006:

All four samples were processed twice due to low yields caused by matrix effects. The MDA for samples 9521-O000-015F and 9521-0000-008F are greater than the MDA. Except as noted, the LCS, sample duplicate, batch blank and sample results are within contractual requirements.

Gamma Spectroscopy Gamma Soec by method RICH-RC-5017:

Seventeen of the eighteen requested radionuclides have been reported for each sample. The Bi-212 was over eight half lives since collection, therefore, not reported.

Except as noted, the LCS, sample duplicate, batch blank and sample results are within required limits.Liquid Scintillation Counting Tritium by method RICH-RC-5007:

All results are below the CRDL and/or below the MDC. The LCS, sample duplicate, batch blank and sample results are within contractual requirements.

Uncertainty Estimation SiT 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 Rx.y.z,...).

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

The individual component uncertainties

(~j) 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 (uie) 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/v n), 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.

Summary Report I. Introduction On October 24, 2002, three soil samples were received at STL Richland (STLR) for radiochemical analysis on one chain-of-custody (00029). Upon receipt, the samples were assigned to Lot Number J2J240267 with the laboratory ID numbers to correspond with the Bechtel Corp. (BCT) specific IDs as listed on the cover page.II. Analytical Results/Methodology The analytical results for this report are presented by laboratory sample ID. Each set of data includes sample identification information; analytical results and the appropriate associated statistical errors.The requested analyses are: Gas Proportional Counting Strontium-90 by method RICH-RC-5006 Gamma Spectroscopy Gamma Spec by method RICH-RC-5017 Liquid Scintillation Counting Tritium by method RICH-RC-5037 2 STL RICHLAN~D Bechtel Corporation December 19, 2002 Page 2 HI. Quality Control The analytical results for each analysis performed under SDG 21410 includes a minimum of one Laboratory Control Sample (LCS) and one method (reagent) blank and one duplicate sample analysis.

Any exceptions have been noted in the "Comments" section.QC and sample results are reported in the same units.IV. Comments Gas Proportional Counting Strontium-90 by method RICH-RC-5006:

The LCS, sample duplicate, batch blank and sample results are within contractual requirements.

Gamma Spectroscopy Gamma Spec by method RICH-RC-5017.

Seventeen of the eighteen requested radionuclides have been reported for each sample. The Bi-212 was over eight half lives since collection, therefore, not reported.

Except as noted, the LCS, sample duplicate, batch blank and sample results are within required limits.Liquid Scintillation Counting Tritium by method RICH-RC-5007:

The entire sample was inadvertently used for gamma analysis for 9521-0000-021F (client was notified via email on 11/27/02), therefore, no tritium fraction was saved before gamma analysis.All results are below the CRDL and/or below the MDC. The LCS, sample duplicate, batch blank and sample results are within contractual requirements.

I certify that this Certificate of Analysis is in compliance with the SOW, both technically and for completeness, for other than the conditions detailed above. Release of the data contained in this hard copy data package has been authorized by the Laboratory Manager, or a designee as verified by the following signature.

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

• fx,y.z....).

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 root of the 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.

The derivation of the general "Law of Propagation ol Errors" equations and specific example are available on request.STL Rtchland rDtGencralltfo v3.72 STL RICHLAND 4 Report Definitions Action Lev An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action Level.
