SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9522-0001 (Southeast Site Grounds (non-protected area) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 2 six thousand nine hundred and seventy two square meters (6,972 M ) of uninhabited, undeveloped land and is located approximately one thousand and fifty five feet (1,055 ft) 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 9522-0002, land Survey Unit 9522-0003 and land Survey Unit 9522-0004 to the north (called north as oriented with the north to south flow of the Connecticut River), the Discharge Canal to the west, land Survey Unit 9539-0001 to the south, and land Survey Unit 9532 to the east. The survey unit is located along the southern boundary of Survey Area 9522, from the northern transmission tower south to the owner-controlled area fence. It is comprised mostly of rock outcroppings, rock ledge, underbrush and trees. The eastern portion of the survey unit has a moderate slope running east to west. The Independent Spent Fuel Storage Installation (ISFSI) Haul Road runs north to south along the western portion of the survey unit. The reference coordinates associated with this survey unit are E009 through E016 by S078 through S081 (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 9522-0001 consisted of: a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "InitialCharacterizationReport" and the "HistoricSite Assessment Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walk-down." A review of the "Initialand Supplemental CharacterizationReports" as well as the previous "Classification Basis Summaries" was performed. Survey Unit 9522-0001 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. Revision 0 3

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD 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". Open land Survey Area 9522 was at one time an open land 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. This action raised 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 the 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. It appears based upon a review of the photographs and historical documents that Survey Unit 9522-0001 was not developed and used in the same manner as the remainder of the survey area to the north, mainly due to the physical geography of the survey unit and its lack of proximity to the south boundary of the RCA during plant operations. Leaks and spills that occurred during plant operations that affected the northern survey units in Survey Area 9522, did not affect Survey Unit 9522-0001 as the natural slope of the survey area directed flow in an east to west direction away from the survey unit. Subsequently, the Revision 0 4

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD operational incidents impacting the northern portions of the survey area do not seem to specifically apply to Survey Unit 9522-0001. During previous characterization surveys, focus was given to the northern survey units in Survey Area 9522 as most of the historical events occurred in these area. Minimal survey data was available that distinctively addressed Survey Unit 9522-0001. Subsequently, a Survey and Sampling Work Plan (SSWP X2. SSWP-06-09-006) was developed to specifically characterize the soils in Survey Unit 9522-0001. This survey plan was implemented in October of 2006. Six (6) soil samples were collected to aid in the characterization of this area and to provide sample data with regard to types and quantities of radioactive material present in the surface soil. During scanning, several areas were identified with slightly elevated readings, which prompted the collection of three (3) additional investigation soil samples at those locations. All samples were collected and analyzed by gamma spectroscopy. Two (2) of the soil samples were analyzed by an approved off-site laboratory for the presence of "Hard-to-Detect" (HTD) radionuclides. Cs-137 and Co-60 was positively identified in six (6) of the nine (9) samples at concentrations greater than MDA but far less than their respective Operational DCGL. In addition, Sr-90 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) but at concentrations less than 5% of the Operational DCGL. Subsequently, Sr-90 was deselected as an isotope of concern in accordance with Section 5.4.7.2 of the LTP. Statistical quantities (mean, median and standard deviation) from the 2006 characterization survey conducted under SSWP 06-09-006 are provided in Table 1. Table 1 - Basic Statistical Quantities for Cs-137 and Co-60 from the 2006 Characterization Survey Cs-137 Co-60 (pCi/g) (pCi/g) Minimum Value: 2.05E-02 -4.58E-02 Maximum Value: 2.55E+00 1.08E-01 Mean: 6.32E-01 2.05E-02 Median: 2.04E-01 5.63E-03 Standard Deviation: 8.96E-01 4.37E-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. Revision 0 5

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD 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 DataQuality Objectives. Based upon a review of the historical information and the results of the Characterization Survey data, 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, "Preparationof 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 would 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 9522-0001 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 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. Revision 0 6

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD Equation I HTotal=Hsoil+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/yrFuturoGw 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.

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 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 2006 to establish the radiological condition Survey Unit 9522-0001 for FSS. Cs-137 and Co-60 were the only two (2) gamma emitting radionuclides reported in concentrations with the potential for exceeding the screening criteria. Sr-90 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) but at concentrations less than 5% of the Operational DCGL. Subsequently, Sr-90 was deselected as an isotope of concern in accordance with Section 5.4.7.2 of the LTP. 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 9522-0001 (refer to Section 3). The characterization survey did not identify any HTD radionuclides of concern for this survey unit. Subsequently, surrogate DCGLs were not required 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. Radionuclide screening or de-selection is a process where the dose contribution from 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. Revision 0 9

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 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, "Determinationof the Number of Surface Samples for FinalStatus Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.5 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting relative shift was 2.99. 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 (10CFR20, 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. 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 2 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. Revision 0 10

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 Presentat 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 one (1) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function. Revision 0 I1I Revision 0 11

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD 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 this survey unit, it was determined that scanning was required in three (3) separate areas. The total surface area to be scanned was approximately 25% of the survey unit. A combination of two of the scan areas resulted in approximately 100% scan coverage of the section of the ISFSI Haul Road contained in this survey unit. A map of the scan grid locations is provided in Attachment 1. 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.

5. 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.

Three (3) scan areas were established that constituted approximately 25% of the surface area of Survey Unit 9522-0001. 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 4,210 counts per minute (cpm) up to 9,750 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-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 25% 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. Fifteen (15) 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 Custodyfor FinalStatus Survey Samples." Two (2) samples (9522-0001-008F and 9522-0001-014F) were randomly selected for HTD radionuclide analysis. The implementation of surve' specific quality control measures included the collection of one (1) sample (9*22-0001-009F) for "split sample" analysis. Revision 0 13 Revision 0 13

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field split and the eight (8) investigative samples using gamma spectroscopy. Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). HowNever, Cs-137 and Co-60 were the only gamma-emitting radionuclides reported in concentrations exceeding the de-selection criteria. Cs-137 was identified in fourteen (14) and Co-60 was identified in three (3) of the fifteen (15) 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. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 7. Revision 0 15

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. Sr-90 was positively identified (i.e., a result greater than two standard deviations uncertainty) in both of the 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. Revision 0 16 Revision 0 16

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD The analytical results for Sr-90 in the two (2) samples selected for HTD analysis respectively equated to 3% and 73% 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 were subjected to additional analysis for the presence of Sr-90.

7. 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 ". There was acceptable agreement between the field split results at location 9520-0001-009.

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 Eight (8) investigative samples were collected from scan area 1, scan area 2 and scan area 3 at locations exhibiting elevated scan readings. 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 were 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 0.841 Co-60 0.008 Sr-90 0.151 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 Revision 0 19 Revision 0 19

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD 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 hard-to-detect radionuclides and the easy-to-detect radionuclides. The surrogate DCGL is computed as follows: Equation 4 S Surrogale C _ DCGL 3 DCGL=+ Where: DCGLsur = Surrogate radionuclide DCGL DCGL 2,3..., = 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 SurrogateDCGL(Uc-137 ) .151 =2.80 pCig (5S. 3 8 (C-1 3 7 ) r+1 .0 5 (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 2.80 pCi/g. The samples are denoted as shown in Table 6, with the sample results shown in Table 11 below.

The Operational DCGL for Cs-137 has been adjusted to 2.80 pCi/g as a surrogate to account for the potential presence of HTD radionuclide Sr-90.

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 An addendum to the FSS plan was initiated on November 13, 2006 to replace sample location 9522-0001-007F, which was determined to be inaccessible due to the presence of a rock ledge and heavy brush. Sample location 9522-0001-016F was determined randomly using VSP.

Additional analysis 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. Revision 0 21 Revision 0 21

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 2. The preliminary data review consisted of 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. 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 DCGL0 p: 5.38E+00 2.59E+00 1.05E+00 Minimum Value: 2.77E-02 -7.76E-03 -1.28E-02 Maximum Value: 3.08E+00 5.70E-02 7.66E-01 Mean: 5.70E-0 1 1.32E-02 7.65E-02 Median: 2.91E-01 1. 15E-02 2.88E-02 Standard Deviation: 7.72E-01 1.90E-02 1.95E-01 For Cs-137 and Sr-90, 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 and the difference between the mean and median was about 36% and 24% 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 2.7 for Cs-137 and 3.6 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 No anomalies were noted.

SOUTHEAST SITE GROUNDS (NON-PROTECTED AREA) SURVEY UNIT 9522-0001 RELEASE RECORD

13. CONCLUSION Survey Unit 9522-0001 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.

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 2. The dose contribution from soil is 3.126 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 5.126 mrem/yr TEDE. Therefore, Survey Unit 9522-0001 is acceptable for unrestricted release.

  • A quality control analyte recovery is outside of specified acceptance criteria
    • Analyte is a surrogate compound
  • Result is less than value reported

> Result is greater than value reported RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL A The TIC is a suspected aldol-condensation product B Target analyte was detected in the associated blank B Metals-Either presence of analyte detected in the associated blank, or MDL/IDL < sample value < PQL BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample d 5-day BOD-The 2:1 depletion requirement was not met for this sample E Organics-Concentration of the target analyte exceeds the instrument calibration range E Metals-%difference of sample and SD is >10%. Sample concentration must meet flagging criteria H Analytical holding time was exceeded h Preparation or preservation holding time was exceeded J Value is estimated N Metals-The Matrix spike sample recovery is not within specified control limits N Organics-Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based on nearest internal standard response factor N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the reporting limit UI Gamma Spectroscopy-Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound Z Paint Filter Test-Particulates passed through the filter, however no free liquids were observed.

UI Gamma Spectroscopy--Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound A RPD of sample and duplicate evaluated using +/-RL. 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. 102

** 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. 61

UI Gamma Spectroscopy--Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound A RPD of sample and duplicate evaluated using +/-RL. 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
