The survey unit is bounded as follows: land Survey Unit 9522-0006 and land Survey Unit 9522-0007 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Unit 9522-0004 to the west, land Survey Unit 9522-0001 to the south, and land Survey Unit 9522-0002 to the east. The survey unit is located in the approximate center of Survey Area 9522. The majority of the survey unit is flat and de-vegetated. This is a result of soil grading in support of previous remediation. The southeast quadrant of the survey unit contains rock outcroppings, rock ledge, underbrush and trees. The survey unit has a moderate slope running from southeast to northwest. The reference coordinates associated with this survey unit are EO 11 through E013 by S075 through S078 (refer to "HNP 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 9522-0003 consisted of: a) A review of the 1OCFR50.75 (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 "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" was performed. Survey Area 9522 includes a former survey area, 9308, that was consolidated into Survey Area 9522 in 2006. This survey area was initially designated as Class 2 during the development of the LTP.Revision 0 3 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD 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.Survey Unit 9522-0003 was created in 2006 under Revision 4 of the LTP and was designated as Class 1.Open land Survey Area 9522 was at one time an open land area immediately adjacent to the southern boundary of the Radiologically Controlled Area (RCA) and security fences. Initially, only a small section of the north side of the unit was paved, with the remainder of the unit gradually sloping down to the original site elevation. As the result of plant operations, there was a need to expand the industrial area to support plant operations and to control exposure to radiation. According to the "Haddam Neck Plant Historic Site Assessment Supplement, " plant photos reveals that the area was gradually filled in from approximately 1972 to between 1974 and 1976, with soil that may have originated from on-site, raising the elevation up to site grade, thereby facilitating a reconfiguration and expansion of the RCA and security protected area. Photos taken in 1976 show that the area was landscaped with grass and small trees and was probably given the name "ball-field" at that time. Over the next several years, additional fill was brought in. By 1987, photos show that half of the survey area was paved and occupied with buildings. It is estimated that the elevation in the survey area may have increased by up to five (5) feet from the original site grade.Survey Area 9522 was impacted by several radiologically significant events during plant operations. These include the discovery of several discrete sources of elevated activity on the ball-field in March 1980, the spill of radioactive liquid into an uncontrolled drain system in February of 1989 and the discovery of several discrete particles outside of the RCA in 1995.Additionally, a portion of Survey Area 9522 was used as a temporary laydown area for the Steam Generator Lower Assemblies (SGLAs) and the Pressurizer until these components where shipped off-site for disposal in 2001. All of these events occurred in the northern portion of Survey Area 9522.According to PIR 89-35, a section of Survey Area 9522 was contaminated in February 1989 following the release of radioactive material into an uncontrolled drain in the Spent Fuel Building. The drain discharged directly to an open trench that drained into a marshy area of the site. Freezing conditions limited the amount of radioactive material that left the protected area. The unanticipated release of radioactive material was identified during a routine radiological surveillance of the site. The area was remediated in 1989 to the established release criteria at the time (1E-5 jiCi/g) and, according to memo CH 89-854, the Chemistry Group initiated a sampling program at the drainage site to monitor activity.Revision 0 4 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Adverse Condition Report (ACR) 95-0250 states that in 1995, several discrete particles were found outside of the RCA, but within the Industrial Area in Survey Area 9522. In addition, two (2) other areas exhibiting elevated activity were identified in 1997. In all cases, the areas of elevated activity were removed upon discovery. In May of 2005, a Survey and Sampling Work Plan (SSWP X2. 05-05-008) was developed as a post-remediation Radiological Assessment (RA) and implemented to characterize the surface soil in this survey area. Seventeen (17)soil samples were collected as part of the effort to provide sample data with regard to types and quantities of radioactive material present in the surface soil.The soil samples were analyzed by the on-site laboratory. A review of this sample data shows Cs-137 and Co-60 to be the primary radionuclides of concern, with both isotopes reported at fairly low concentrations. As part of the groundwater characterization effort, a large number of surface and sub-surface soil samples were taken and analyzed for the full suite of"Hard-to-Detect" (HTD) radionuclides specified in the LTP, Table 2-12,"Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 2. No HTD radionuclides were positively identified in concentrations greater than the screening criteria during the performance of these surveys.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. Based upon the results of the previous surveys, as it was determined that it was unlikely that HTD radionuclides were present in any significant concentration, none of the soil samples taken as part of this characterization survey were analyzed for HTD radionuclides. Statistical quantities (mean, median and standard deviation) from the 2005 characterization survey conducted under SSWP 05-05-008 are provided in Table 1.Table 1 -Basic Statistical Quantities for Cs-137 and Co-60 from the 2005 Characterization Survey Cs-137 Co-60 (pCi/g) (pCi/g)Minimum Value: 6.98E-05 -6.69E-02 Maximum Value: 4.01E+00 1. 16E+00 Mean: 9.85E-01 1.60E-01 Median: 3.50E-01 2.1OE-02 Standard Deviation: 1.28E+00 3.52E-01 Revision 0 5 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD 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 identification of radioactive material above the Derived Concentration Guideline Levels (DCGLs), and the need for radiological remediation, it was concluded that there was some probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class 1 (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.The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9522-0003 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).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 Revision 0 6 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD 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 1 HiTotal =Hsoil +HExistingGW +HFutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr Total Effective Dose Equivalent (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 mremnyrsoil + 2 mremlyrExisting GW+ 0 mrem/yrFutureaw 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 7 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Table 2 -Radionuclide Specific Base Case Soil DCGLs, Operational DCGLs and Required Minimum Detectable Concentrations (MDCs)Radionuclide ) Base Case Soil Operational DCGL Required MDC DCGL (pC/g) ( (pC/g) (3) (pC/g) (4)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 OE+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-01 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-01 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+01 1.82E+01 1.07E+00 Am-241 (5) 2.58E+01 1.75E+01 1.03E+00 Pu-241 8.70E+02 5.92E+02 3.48E+01 Cm-243/244 2.90E+01 1.97E+01 1.16E+00 (1) Bold indicates those radionucldies considered Hard to Detect (HTD)(2) The Base Case Soil DCGL(s) are specified by the LTP in Chapter 6 and are equivalent to twenty-five (25) mrem/yr TEDE (3) The Operational DCGL is equivalent to achieving seventeen (17) mrem/yr TEDE (4) The required MDC is equivalent to achieving one (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 Revision 0 8 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Soil samples were collected in 2005 to establish the radiological condition of Survey Unit 9522-0003 for FSS. Cs-137 and Co-60 were the two (2) 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.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 both Cs-137 and Co-60 would be the radionuclides of concern in Survey Unit 9522-0003 (refer to Section 3). The characterization survey did not specifically address HTD radionuclides of concern for this survey unit. Based on other survey data, surrogate DCGLs were not required as part of the survey design for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performance of this FSS would be evaluated to ensure adequate survey design.As the survey unit is classified as a Class 1 surface soils area, and discrete, elevated areas of contamination was possible, the application of the Elevated Measurement Comparison (EMC) remained an option.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 0 9 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 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 Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.5 to achieve a relative shift (A/o)in the range of 1 and 3. The resulting relative shift was 1.82. 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 (1OCFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.The survey design specified sixteen (16) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information and Characterization Survey data, the acquisition of additional judgmental surface soil samples from within this survey unit was deemed unnecessary. 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 1 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 9522-0003-0OlF 236413.31 669166.75 9522-0003-002F 236379.26 669147.10 9522-0003-003F 236379.26 669186.41 9522-0003-004F 236379.26 669225.73 9522-0003-005F 236345.21 669127.44 9522-0003-006F 236345.21 669166.75 9522-0003-007F 236345.21 669206.07 9522-0003-008F 236345.21 669245.39 Revision 0 10 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9522-0003-009F 236345.21 669284.70 9522-0003-OIOF 236311.16 669107.78 9522-0003-011F 236311.16 669147.10 9522-0003-012F 236311.16 669186.41 9522-0003-013F 236311.16 669225.73 9522-0003-014F 236277.11 669127.44 9522-0003-015F 236277.11 669166.75 9522-0003-016F 236277.11 669206.07 Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis. 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 LTP requires a minimum of 5% of the samples taken for non-parametric statistical testing be selected for QC evaluation. 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 one (1) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function.The LTP specifies a required scanning coverage of 100% for outdoor Class 1 areas.For this Class 1 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0047. 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.A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 9522-0003. 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 5,720 counts per minute (cpm) up to 10,600 cpm.The scan area was 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-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 100% 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.Sixteen (16) 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 (9522-0003-006F and 9522-0003-016F) were randomly selected for HTD radionuclide analysis.The implementation of survey specific quality control measures included the collection of one (1) sample (9522-0003-008F) for "split sample" analysis.Revision 0 13 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD 6. SURVEY RESULTS All field survey activities were conducted between October 27, 2006 and November 20, 2006.The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels.

Sample locations 9522-0003-004F and 9522-0003-016F were moved accordingly. Revision 0 14 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD The scan areas, that comprised approximately 100% of the total surface area for the survey unit, were scanned for elevated radiation levels.

The laboratory analyzed the sixteen (16) samples collected for non-parametric statistical testing, the associated field splits and the nineteen (19) investigative 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 gamma-emitting radionuclides reported in concentrations exceeding the de-selection criteria.Cs-137 was identified in fifteen (15) and Co-60 was identified in three (3) of the sixteen (16) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results 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.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses performed met the required minimum MDC.Sr-90 was positively identified (i.e., a result greater than two standard deviations uncertainty) in both of the two samples analyzed for HTD radionuclides. 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. For Sr-90, the Operational DCGL is 1.05 pCi/g to achieve a TEDE of seventeen (17) mrem/yr. The analytical results for Sr-90 in the two samples selected for HTD analysis respectively equated to 3%and 9% of the Operational DCGL. Subsequently, Sr-90 was added as a radionuclide of concern for this survey unit. In response, all samples that comprised the statistical sample population for this survey unit was subjected to additional analysis for the presence of Sr-90.

QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. One sample location was 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 detected in sufficient quantities in both samples to evaluate in accordance with procedure. Revision 0 19 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Analysis of the split sample results found the comparison ratio for Cs-137 to be slightly outside of the acceptable agreement range for the established resolution. Cs-137 has a likelihood to be tightly bound to organic mater in the sample matrix. Subsequently, it is presumed that there was inadequate homogeneous mixing of the sample-split matrix as the process is not very effective in dispersing the organic material uniformly throughout the aliquot due to the physical form of the organic material itself. Since K-40 was found to be present at an acceptable level of agreement, no further action is warranted. 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 Nineteen (19) investigative surface soil samples were collected from scan areas exhibiting elevated scan readings. These confirmatory soil samples were analyzed for Cs-137 and Co-60 in accordance with the DQOs used during the survey design.As previously stated, Sr-90 was positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in the two (2) surface soil samples selected for HTD analysis. Consequently, Sr-90 was added as a radionuclide of concern for this survey unit. All surface soil samples comprising the statistical sample population was subjected to additional analysis for the presence of Sr-90. Subsequently, the statistical sample population as a whole was evaluated to assess the distribution of the detected radionuclides of concern. The radionuclide distribution percentage for each sample in the population was calculated by dividing the concentration of each detected radionuclide by the total activity concentration in the sample, expressing the abundance of the specific nuclide in the sample compared against the total activity. The mean radionuclide distribution was then calculated by taking the average of the individual sample distribution fractions. The resultant distribution fractions are presented in Table 10 below.Table 10 -Radionuclide Distribution Fraction for the Radionuclides of Concern in the Statistical Soil Sample Population Detected Radionuclide Distribution Fraction Cs-137 0.826 Co-60 0.036 Sr-90 0.138 Revision 0 20 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD The potential presence of Sr-90 in the investigative samples taken that were not subjected to direct analysis for Sr-90 was addressed by using a surrogate relationship to another detectable radionuclide as recommended in NUREG-1575 (MARSSIM), in this case Cs-137. To demonstrate compliance with the release criteria by directly comparing the individual investigative sample results with the DCGL(s) as required by MARSSIM, the DCGL for the surrogate radionuclide, in this case Cs-137 was scaled to account for the fact that it was being used as an indicator for additional radionuclides, in this case Sr-90. This result is referred to as the surrogate DCGL.The surrogate DCGL was computed based on the distribution ratio between the difficult-to-detect radionuclides and the easy-to-detect radionuclides. The surrogate DCGL is computed as follows: Equation 4 1[DCL DCGL2+ DCGL 3+ DCGLJ Where: DCGLsur = Surrogate radionuclide DCGL DCGL 2 , 3...n = DCGL for radionuclides to be represented by the surrogate Rn = Ratio of concentration (or nuclide mixture fraction) of radionuclide "n" to surrogate radionuclide Using the DCGLs presented in Table 2 and the soil nuclide distribution presented in Table 10, the following surrogate calculation was deduced;Equation 5 Sur-) 1 26 = 2.90 pCi / g) +1 .13 8ý5.3 8 (CsI37) l.OS(sr--90) Subsequently, the surrogate DCGL that was used for Cs-137 in this survey unit for direct comparison of investigative sample results to demonstrate compliance with the operational dose limit of seventeen (17) mrem per year is 2.90 pCi/g.Revision 0 21 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD The samples are denoted as shown in Table 6, with the sample results shown in Table 11 below.Table 11 -Confirmatory Sample Results Cs-137 Co-60 Unity Fraction pCi/g pCi/g (1) (2)9522-0003-0017-I 8.88E-02 5.45E-03 0.03 9522-0003-0018-1 3.90E-02 7.34E-04 0.01 9522-0003-0019-I 2.40E-02 7.19E-03 9522-0003-0020-I 4.95E-02 9.93E-03 0.02 9522-0003-0021-I 7.95E-02 1.1OE-02 0.03 9522-0003-0022-I 9.49E-02 -6.1 OE-03 0.03 9522-0003-0023-I 1.83E-01 2.27E-02 0.07 9522-0003-0024-I 2.28E-01 2.29E-02 0.09 9522-0003-0025-I 8.49E-02 5.41E-03 0.03 9522-0003-0026-1 3.44E-0 1 0.OOE+00 0.12 9522-0003-0027-I 2.25E-02 1.1 5E-04 -9522-0003-0028-I 1.53E-02 -1 .78E-03 -9522-0003-0029-I 0.OOE+00 1.OOE-03 -9522-0003-0030-I 2.95E-02 1.32E-02 -9522-0003-0031-I 4.13E-0 1 0.OOE+00 0.14 9522-0003-0032-I 8.20E-02 -4.98E-03 0.03 9522-0003-0033-I 1.81E-01 8.23E-03 0.06 9522-0003-0034-I 4.78E-01 0.OOE+00 0.17 9522-0003-0035-I 8.35E-02 0.OOE+00 0.03 (1) The Operational DCGL from Table 2 is 5.38 pCi/g for Cs-137 and 2.59 pCi/g for Co-60 to achieve seventeen (17) mrem/yr TEDE respectively.

REMEDIATION AND RESULTS Significant remediation activities occurred in this survey unit prior to FSS. All above grade and below grade commodities and facility systems were removed and properly dispositioned. Contaminated soils that exceeded the screening criteria in effect for groundwater dose compliance were identified, excavated and removed as part of the "Zone 12" and "Excavation 7" remediation projects which occurred in this survey area. All excavations were characterized and backfilled with "clean" fill prior to performing FSS. As a byproduct of remediation activities, the ground area is comprised of barren dirt with no vegetation, and the soils have been graded relatively flat to the corresponding elevation of the survey units to the north and west. The majority of the southeastern half of the ground in this survey unit is comprised of stone from the ledge outcroppings along the eastern ridge. 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 Additional evaluation to account for the presence of Sr-90 was performed on the statistical survey population as a consequence of the results from the initial samples selected for HTD analysis. This was to ensure that the dose consequence from the possible presence of Sr-90 in the surface soils in this survey unit was adequately addressed.

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.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 1.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. The basic statistical quantities for the statistical sample population are provided below in Table 12.Revision 0 23 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Table 12 -Basic Statistical Quantities for Cs-137, Co-60 and Sr-90 from the Final Status Survey Cs-137 Co-60 Sr-90 pCi/g pCi/g pCi/g DCGLop: 5.38E+00 2.59E+00 1.05E+00 Minimum Value: 2.42E-02 -1.70E-02 -2.27E-02 Maximum Value: 7.30E-01 3.67E-02 1.21E-01 Mean: 2.26E-01 9.07E-03 2.54E-02 Median: 9.65E-02 9.20E-03 1.76E-02 Standard Deviation: 2.41E-01 1.38E-02 4.02E-02 For Cs- 137 and Sr-90, the range of the data, about three (3) 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 and the difference between the mean and median was about 54% and 20% 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 1.4 for Cs-137 and 1.1 for Sr-90.Co-60, although included in the FSS plan for compliance purposes, was positively identified in only three (3) of the fifteen (15) samples collected for non-parametric statistical testing. Assessment of the basic statistical quantities 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 are provided in Attachment 4.12. ANOMALIES Analysis of the split sample results found the comparison ratio for Cs-137 to be slightly outside of the acceptable agreement range for the established resolution. Cs-137 has a likelihood to be tightly bound to organic mater in the sample matrix. Subsequently, it is presumed that there was inadequate homogeneous mixing of the sample-split matrix as the process is not very effective in dispersing the organic material uniformly throughout the aliquot due to the physical form of the organic material itself. Since K-40 was found to be present at an acceptable level of agreement, no further action is warranted. Revision 0 24 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD 13. CONCLUSION Survey Unit 9522-0003 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 was not required.All identified radionuclides of concern 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 1.The dose contribution from soil is 1.18 mremlyr 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 3.18 mrem/yr TEDE. Therefore, Survey Unit 9522-0003 is acceptable for unrestricted release.14.

Concentrations are <5X the RL h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.** Indicates analyte is a surrogate compound.A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations. Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.154 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD ATTACHMENT 4 (DQA RESULTS)Revision 0 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD ATTACHMENT 4A (PRELIMINARY DATA REVIEW)Revision 0 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Attachment 4 Survey Unit: 9522-0003 Area Description Southeast Grounds (non-protected) Classification 1 Survey Media Surface Soils Type of Survey Final Status Survey Number of Measurements 16 Static, 19 Investigative STATISTICS on TOTAL POPULATION STATISTICS on NON-PARAMETRIC POPULATION Cs-137 Co-60 Sr-90 Cs-137 Co-60 Sr-90 DCGLop (pCi/g): 5.38E+00 2.59E+00 1.05E+00 DCGLop (pCi/g): 5.38E+00 2.59E+00 1.05E+00 Minimum Value: 0.OOE+00 -1.70E-02 -2.27E-02 Minimum Value: 2.42E-02 -1.70E-02 -2.27E-02 Maximum Value: 1.01E+00 3.67E-02 1.21E-01 Maximum Value: 7.30E-01 3.67E-02 1.21E-01 Mean: 1.98E-01 7.06E-03 2.54E-02 Mean: 2.26E-01 9.07E-03 2.54E-02 Median: 8.98E-02 6.70E-03 1.76E-02 Median: 9.65E-02 9.20E-03 1.76E-02 Standard Deviation: 2.38E-01 1.10E-02 4.02E-02 Standard Deviation: 2.41E-01 1.38E-02 4.02E-02 DCGLsur (pCi/g): 2.90E+00 Nuclide Distribution: 0.826 0.036 0.138 Cs-137 Co-60 Sr-90 GPS Coordinates1 1IrT Sample ID Result 2 MDA Result MDA Result MDA 2cr I____ Identified j 2cr ____ Identified 2cr Identified North East (pci/g) (pCilg) (pCi/g) (pci/g) (pCi/g) (pCi/g)9522-0003-001F 236413.31 669166.75 3.11E-02 0.037 4.51E-02 6.20E-03 0.025 4.64E-02 1.11E-02 0.020 3.37E-02 9522-0003-002F 236379.26 669147.10 1.59E-01 0.030 3.06E-02 + -2.91E-03 0.018 3.28E-02 1.21E-01 0.028 3.44E-02 +9522-0003-003F 236379.26 669186.41 3.42E-01 0.053 4.66E-02 + 1.14E-02 0.026 4.93E-02 4.78E-02 0.024 3.59E-02 +9522-0003-004F 236379.26 669225.73 7.13E-02 0.027 3.48E-02 + -5.45E-03 0.027 3.53E-02 5.04E-02 0.026 3.80E-02 +9522-0003-005F 236345.21 669127.44 9.08E-02 0.033 3.56E-02 + -6.60E-03 0.015 2.67E-02 3.77E-02 0.022 3.27E-02 +9522-0003-006F 236345.21 669166.75 1.37E-01 0.040 2.94E-02 + 8.71E-03 0.019 3.39E-02 3.37E-02 0.022 3.29E-02 +9522-0003-007F 236345.21 669206.07 6.13E-01 0.060 4.64E-02 + 3.03E-02 0.028 5.82E-02 + -2.27E-02 0.017 3.28E-02 9522-0003-008F 236345.21 669245.39 7.30E-01 0.049 2.93E-02 + 1.18E-02 0.017 3.16E-02 4.47E-02 0.014 2.12E-02 +9522-0003-009F 236345.21 669284.70 6.95E-01 0.065 4.05E-01 + 9.68E-03 0.032 4.62E-02 2.40E-02 0.012 1.97E-02 +9522-0003-010F 236311.16 66910778 7.69E-02 0.027 2.59E-02 + 1.15E-02 0.019 3.35E-02 -5.79E-03 0.011 1.98E-02 Fraction of DCGL 0.019 0.144 0.113 0.059 0.050 0.061 0.104 0.183 0.156 0.013 REVISION Page 1 of 2 SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD Attachment 4 Cs-137 Co-60 Sr-90 GPS Coordinates Sample ID Result MDA Result MDA Result MDA 2a Identified 2y Identified 2a Identified North East (pCi/g) (pCi/g) (pCi/g) (pCilg) (pCilg) (pCi/g)9522-0003-0011 F 236311.16 669147.10 2.42E-02 0023 3.60E02 0 + 9.98E-03 0017 3.42Eo02 -7.57E-03 0013 2.29E-02 9522-0003-0012F 236311.16 669186.41 7.76E-02 0.036 3.67E-02 + -1.70E-02 0.021 3.54E-02 -8.30E-03 0.011 2.04E-02............ ........ ........ .......... ... ........ ....................... .. ... .... ... ......... ..... ....... .......... ... ..... .......... ..... ..... ..... ... ............. i....... ... .. ....... ...... ........... ............ ..... .......... ............................. ,.... .... ..... ... ...... ..... ....9522-0003-0013F 236311.16 669225.73 2.87E-01 0.049 3.67E-02 + 5.72E-03 0.021 4.11 E-02 7.89E-03 0.010 1.63E-02 9522-0003-0014F 236277.11 669127.44 9.63E-02 0.038 2.90E-02 + 2.71E-02 0.020 4.22E-02 + -1.45E-02i 0.010 i 1.89E-02.. .... ... ... ...... .... ... .... ..................... .... ..... ....... ......... .. .............. .... ......... .....- ---- -- -- ---------

Description:

Comparison of split samples collected from sample measurement location #8 and analyzed using gamma spectroscopy by off-site Vendor Laboratory. The standard sample was 9522-0003-008F, the comparison sample was 9522-0003-0008FS.STANDARD COMPARISON Radionuclide Activity Standard Resolution Agreement Activity Standard Comparison Acceptable Value Error Range Value Error Ratio (Y/N)Cs-137 7.30E-01 0.025 30 0.75 -1.33 1.01E+00 0.040 1.38 N K-40 L.15E_+01 0.3285 35 0.75- 1.33 1.11E+01 0.51 0.97 Y Loomments/torrective Actions: in consiaeration or me Cs- I i results, Cs-137 has a likelihood to be tightly bound to organic mater in the sample matrix, one would not necessarily expect it to be homogeneously mixed as processing of the sample-split aliquot is not very effective in dispersing the organic material uniformly through the sample aliquot due to the physical form of the organic material itself. Since K-40 was found to be present at an acceptable level of agreement, no further action is warranted. Sable is proviaea to snow acceptance criteria used to assess split samples.Resotution 4-7 8-15 16 -50 51 -200>200 Agreement Range 0.5 -2.0 0.6 -1.66 0,75 -1.33 0.80 -1.25 0.85 -1.18 Page t of I SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA)SURVEY UNIT 9522-0003 RELEASE RECORD ATTACHMENT 4E (COMPASS DQA WITH POWER CURVE)Revision 0 DQA Surface Soil Report Assessment Summary Site: Planner(s): Survey Unit Name: Report Number: Survey Unit Samples: Reference Area Samples: Test Performed: Judgmental Samples: Assessment
