SURVEY UNIT DESCRIPTION Survey Unit 9520-0003 (Southwest Site Storage Area) is designated as Final Status Survey (FSS) Class 2 and consists of 8,106 m2 (2.0 acres) of uninhabited open land located approximately 1,661 feet from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1). The survey unit is bounded as follows: land Survey Unit 9520-0002 to the north (called north as oriented with the north to south flow of the Connecticut River), the Discharge Canal to the east, land Survey Unit 9530-0004 to the south, and the Connecticut River to the west. The survey unit is relatively level open space in the middle of the peninsula.

The restoration of the peninsula for FSS has removed most of the surface interference in the survey unit.The reference coordinates associated with this survey unit are E005 through E010 by S086 through S093 (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) based on the Connecticut State Plane System North American Datum (NAD) 1927.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification.

" The "Classification Basis Summary" conducted for Survey Unit 9520-0003 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 1OCFR50.75(g)(1) database report and historical files shows a documented history of the use of this survey unit as a radioactive materials storage area. Additionally, at least one (1) case of contamination to underlying soil has been recorded (refer to survey performed 3/23/1985).

Examples of some of the major events are provided below.a) Plant Incident Report (PIR) 80-37 reported the discovery of three (3)discrete sources of elevated activity on the Southeast Site Storage area in March 1980, along with other areas around the site. Two (2) of the discrete sources were identified within nearby Survey Unit 9520-0001.

The location of the third discrete source, identified as 3-24-2, was probably in Survey Unit 9520-0002, which is adjacent to Survey Unit 9520-0003, based on a review of the 1980 survey maps.Revision 0 3 Revision 0 3 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD b) Health Physics surveys performed in 1983 and 1985 document the discovery of radioactive material (strainers, bolts, wood pallets, sections of pipe, etc.) on the peninsula.

The 1985 survey documents the discovery of contaminated dirt under a pallet.c) Condition Report (CR) 05-0314: Documents the discovery of excavation spoils, intended for backfill, above the radiological criteria for use as backfill.

These spoils were likely located in Survey Units 9520-0003 and 9520-0004 based on review of the documentation.

According to the CR closure documentation, the affected spoils were removed and packaged for disposal.

Follow-up survey and sampling was performed and the results were below established action levels.A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" was performed.

Survey Unit 9520-0003 was initially designated as Class 2 during the development of the LTP. The source documents, the "Connecticut Yankee Haddam Neck Characterization Report" and "Initial Classification for Survey Areas at Connecticut Yankee", were incorporated by reference in LTP revision 0 (references 2-2 and 2-7 respectively).

The second source document justified a Class 2 designation for those areas for which there was historical evidence of contamination above the Derived Concentration Guideline Levels (DCGLs -refer to Section 2 for definition and description of DCGL), but for which recent surveys had shown that decontamination efforts had occurred and that the radiological conditions were expected to be below the DCGLs. Additional justification for a Class 2 designation based on survey and sampling data was provided as another reference to the LTP by the "Haddam Neck Plant Historical Site Assessment Supplement".

Removal of material and restoration of the peninsula for FSS has been ongoing since 2000, starting with the radiological release of the South Access Point and several abandoned trailers.

The collapse of the Radioactive Material(s)

Area (RMA) boundary and the removal of subsurface commodities has produced a large data set that has helped/characterize the radiological contaminants of concern and extent of contamination.

Co-60 has been identified in the past (refer to the "Haddam Neck Plant Historical Site Assessment Supplement"), and has the potential to exceed the screening criteria (refer to Section 3).Characterization was performed in August 2006 to support final classification and FSS planning.

Statistical quantities (mean, median and standard deviation) from the 2006 characterization survey conducted under SSWP 06-07-006 are provided in Table 1.Revision 0 4 Revision 0 4 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD serveu %-oncentraton kpLi/g) : Maximum Observed Concentration (pCi/g): 1.03E-01 1.41E-01 Mean (pCi/g): 6.63E-02 1.96E-02 Median (pCi/g): 6.86E-02 -2.93E-03 Standard Deviation (pCi/g): 3.74E-02 5.96E-02 The FSS Engineer performed a visual inspection and walk-down during September 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024) which will be a source of dose from residual radioactivity, as discussed in Section 3 under the Data Quality Objectives.

Based upon the results of radiological surveys performed over six years of restoration and the 2006 characterization survey, it was concluded that there was a low probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class 2 (refer to Section 3).3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning used 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 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 indicate that residual activity within the survey unit does not exceed the release criteria.

Therefore, the survey unit does satisfy the primary objective of the FSS plan.The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9520-0003 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).Revision 0 5 Revision 0 5 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD 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 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 future groundwater radioactivity that will be contributed by building basements and footings.The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity.

Equation 1 shows the mathematical relationship between the three (3) components and the total dose.Equation I HTotal =Hsoi +/-+HExistingGW

+HFutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr TEDE from all three (3) components.

The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for CY is nineteen (19) mrem/yr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.This survey area is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is bounded by two (2) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no buried concrete foundations or footings containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component is, therefore, zero (0) mrem/yr TEDE.Equation 2 19 mrem/yrTotal

= 17 mrem/yrsoil

+ 2 mrem/yrExisting GW+ 0 mrem/yrFutureGw The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.Revision 0 6 Revision 0 6 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORDý F -.,;;I H-3 4.12E+02 2.80E+02 1.65E+01 C-14 5.66E+00 3.85E+00 2.26E-01 Mn-54 1.74E+01 1.18E+O1 6.96E-01 Fe-55 2.74E+04 1.86E+04 1.1 0E+03 Co-60 3.81E+00 2.59E+00 1.52E-01 Ni-63 7.23E+02 4.92E+02 2.89E+01 Sr-90 1.55E+00 1.05E+00 6.20E-02 Nb-94 7.12E+00 4.84E+00 2.85E-01 Tc-99 1.26E+01 8.57E+00 5.04E-0 1 Ag- 108m 7.14E+00 4.86E+00 2.86E-01 Cs- 134 4.67E+00 3.18E+00 1.87E-01 Cs-137 7.91E+00 5.38E+00 3.16E-01 Eu-152 1.01E+01 6.87E+00 4.04E-0I Eu-154 9.29E+00 6.32E+00 3.72E-01 Eu-155 3.92E+02 2.67E+02 1.57E+01 Pu-238 2.96E+01 2.01E+01 1.18E+00 Pu-239/240 2.67E+0 1 1.82E+01 1.07E+00 Pu-241 8.70E+02 5.92E+02 3.48E+01 Am-241,5) 2.58E+O1 1.75E+01 1.03E+00 Cm-243/244 2.90E+01 1.97E+01 1.16E+00 I ) Bold inuicates Mose radionucliles consiaerea to ne ilara-to-Detect (JI I U)(2) The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to 25 mrem/yr TEDE (3) The Operational DCGL is equivalent to 17 mrem/yr TEDE (4) The required MDC is equivalent to 1 mrem/yr TEDE (5) Americium-241 can be analyzed by gamma and alpha spectroscopy and is considered to be Easy to Detect (ETD); the preferred result is the alpha spectroscopy's when both analyses are performed Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Soil samples were collected in 2006 to establish the radiological condition of Survey Unit 9520-0003 for FSS. Cs-137 and Co-60 are the only gamma emitting radionuclides reported in concentrations with the potential for exceeding the screening criteria.

The characterization data were used for the survey design and are provided in Table 1.Revision 0 7 Revision 0 7 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 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 required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) 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. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans". The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern in Survey Unit 9520-0003 (refer to Section 3). Other radionuclides identified during this FSS would be evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit based the previous FSS of this survey unit and via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates 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 it is a Class 2 area and discrete, elevated areas of contamination were 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 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 0.95 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting Adjusted Relative Shift was 2.0. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Revision 0 8 Revision 0 8 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD 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.The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing and five (5) samples at biased locations.

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 2 area. Two of the sample locations, 9520-0003-009F and 9520-0003-01OF, were selected randomly since the systematic locations fell within the boundary of Survey Unit 9520-0004, a Class 1 survey unit contained within Survey Unit 9520-0003.

Judgmental sampling was included as a feature of this survey design to account for any anomalies potentially identified in the field.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.T'Ible 3>.Sam ple Meaureni i~Locations with Associated GP'S Coordin'ates~

Two (2) soil samples, or about 10% 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 was 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" and as provided in Table 2.The implementation of 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 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 about 10% of fifteen (15) samples.The LTP specifies a required scanning coverage of 10% to 100% for outdoor Class 2 areas. 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 the historical site assessment, the characterization data available, and the use of the survey unit to store spoils from remediation, it was determined that scanning was required in six (6)separate areas. The total surface area to be scanned was approximately 20% of the survey unit.Revision 0 10 Revision 0 10 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD For this Class 2 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8.

SURVEY IMPLEMENTATION FSS field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0038.

The WP&IR package included a detailed FSS plan, 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.Six (6) scan areas were established that constituted approximately 20% of the surface area of Survey Unit 9520-0003.

Grid lines, one meter wide, were painted on the ground of the scan area. A background survey was performed around the survey unit and it was determined that, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 5,580 counts per minute (cpm) up to 9,920 cpm.The scan areas were established and scanned for elevated readings (see Attachment 2 for all scan results).

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

The E-600 was operated in the rate-Revision 0 I1I Revision 0 11 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD 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. Approximately 20% of the survey unit was scanned.Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification.

At each sample location, a one (1) meter radius around the sample flag or paint mark was scanned for elevated radiation levels.Twenty-four (24) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample 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." Two (2) samples (9520-0003-010F and 9520-0003-039F) were randomly selected for HTD radionuclide analysis.

Sample 9520-0003-039F replaced sample 9520-0003-002F, which was reassigned to another survey unit (refer to Section 10 for additional detail).The implementation of survey specific quality control measures included the collection of two (2) samples (9520-0003-004F and 9520-0003-014F) for "split sample" analysis.6. SURVEY RESULTS All field survey activities were conducted between September 25, 2006 and October 4, 2006.The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan results for sample measurement locations.

The areas were scanned in accordance with the FSS plan on September 26, 2006 through October 2, 2006. Several elevated measurement locations were identified during scanning.

One elevated area warranted analysis on-site since it was twice ambient background.

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field splits, the five (5) biased samples, and the four (4) confirmatory samples using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDCs. Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty).

However, Cs-137 and Co-60 were the only radionuclides reported in concentrations exceeding the de-selection criteria.Cs-137 was identified in thirteen (13) of the fifteen (15) samples collected for non-parametric statistical testing. Cs-137 was the primary radionuclide confirming the DQOs. The mean of the gamma spectroscopic analysis results Revision 0 14 Revision 0 14 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD for the sample population indicated that Cs-137 was present at levels 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.

Co-60 was identified in three (3) of the fifteen (15) samples collected for non-parametric statistical testing.A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 7.9520-0003-003F 5.54E-02 1.42E-02 0.016 9520-0003-004F 2.45E-02 1.33E-02 0.010 9520-0003-005F 1.07E-01 1.78E-02 0.027 9520-0003-006F 6.53E-02 1.94E-02 0.020 9520-0003-007F 1.37E-01 -4.29E-03 0.025 9520-0003-008F 1.99E-01 5.69E-03 0.039 9520-0003-009F 1.71E-01 -5.58E-03 0.032 9520-0003-01OF 4.59E-02 2.48E-02 0.018 9520-0003-01IF 5.77E-02 1.5 1E-02 0.017 9520-0003-012F 2.75E-02 6.71 E-03 0.008 9520-0003-013F 2.80E-02 -8.93E-03 0.005 9520-0003-014F 1.14E-01 1.97E-02 0.029 9520-0003-015F 1.55E-01 1.22E-02 0.034 9520-0003-039F 5.30E-02 -2.5 1E-02 0.010 (1) The Operational DCGL from Table 2 is 5.38 pCi/g for Cs-137 and 2.59 pCi/g for Co-60 used in conjunction with the unity rule to achieve 17 mrem/yr TEDE The off-site laboratory also processed two (2) samples for HTD analysis as required by the sample plan. 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.As previously stated in Section 4 of this report, the criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates.

None of the HTDs, which by analysis, met the criteria for detection (i.e., a result greater than two standard deviations uncertainty).

QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis.

Ten percent (10%) 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". Cs-137 was not detected in sufficient quantities in the field split results at location 9520-0003-004 to evaluate in accordance with procedure.

Evaluation using the reported results for K-40 resulted in acceptable agreement between the field split result at this location.

Cs-137 was not detected in one of the field split results at location 9520-0003-0014.

Evaluation using the reported results for K-40 resulted in acceptable agreement between the field split result at this location.The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation.

Refer to Attachment 4 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS Four confirmatory samples were collected from scan area 4 at locations exhibiting elevated scan readings.

The samples are denoted as shown in Table 6, with the sample results shown in Table 9 below.9520-0003-036F 4.99E-02 2.25E-02 0.018 Revision 0 16 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD 9520-0003-038F 1.24E-01 8.88E-03 0.026 (1) Samples 9520-0003-021F through 9520-0003-034F were reassigned to Class I Survey Unit 9520-0005 (refer to Section 10)(2) The Operational DCGL from Table 2 is 5.38 pCi/g for Cs-137 and 2.59 pCi/g for Co-60 used in conjunction with the unity rule to achieve 17 mrem/yr TEDE 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 is unnecessary and that the remaining residual radioactivity in soil was ALARA.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN One elevated area warranted analysis on-site since the scan measurement was twice ambient background.

The gamma spectroscopy result reported Co-60 above the Operational DCGL. Additional scanning did not identify other elevated areas indicating that the extent of contamination was localized to an area of about 36 square inches (six inches by six inches). A new Class 1 survey unit, Survey Unit 9520-0005, was created based on the sample result around the area of elevated activity and within the borders of Survey Unit 9520-0003.

The change to the FSS plan included the generation of a new sample location to complete the fifteen (15) samples for non-parametric statistical sampling.

The sample location was determined randomly using VSP. Also, most of scanning performed in scan area 1 and scan area 2 is now relevant to Survey Unit 9520-0005. The scanning that was performed in scan area 1 and scan area 2 did not identify elevated areas of activity; and, along with the other four scan areas, the minimum land area to be scanned (>10%) was satisfied for this survey unit.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 evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.Revision 0 17 Revision 0 17 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 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 after the new Class 1 survey unit (9520-0005) was created.The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation).

The mean and median values are well below the Operational DCGL. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power.Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.For Cs-137, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected.

The difference between the mean and median was about 27% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 0.44.Co-60, although included in the FSS plan for compliance purposes, was identified in only three (3) of the fifteen (15) samples collected for non-parametric statistical testing. Data assessment and graphical representation of Co-60 was not considered useful given the limited number of data points to represent the distribution.

All data, assessments, and graphical representations for Cs-137 are provided in Attachment 4.12. ANOMALIES A discrete source of elevated activity was identified during scanning as discussed in Section 10. A new Class 1 survey unit, Survey Unit 9520-0005, was created based on the soil sample result.13. CONCLUSION Survey Unit 9520-0003 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

Elevated Measurement Comparison and remediation was not required.Cs-137 and Co-60 were used for statistical testing to determine the adequacy of the survey unit for FSS.The sample data passed the Sign Test. The null hypothesis was rejected.

The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.

The survey unit is properly designated as Class 2.Revision 0 18 Revision 0 18 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0003 RELEASE RECORD The dose contribution from soil is less than 1 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) mrem/yr TEDE.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 (reference CY memo ISC 06-024); therefore, the dose contribution from future groundwater is zero (0) mrem/yr TEDE.The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity, will not exceed 3 mrem/yr TEDE. Therefore, Survey Unit 9520-0003 is acceptable for unrestricted release.14.
