The survey unit is bounded as follows: Survey Unit 9506-0000 is to the north and west; Survey Area 9508 is to the west, Survey Unit 9526-0000 is to the east and Survey Unit 9514-0000 is to the south.Connecticut Yankee (CY) memorandum, CY-06-093, addresses the abandonment of buried pipes, culverts, concrete, and storm drains onsite that will remain in place at the completion of the decommissioning.

The sidewalk and two (2) electric/telephone duct banks that traverse the site adjacent to the access road will be abandoned in place. Sufficient radiological assessment has been performed to confirm that the components or structures will meet all applicable unrestricted release criteria.The reference coordinates associated with this survey unit are E010 through E014 by S042 through S054 (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 historical information, scoping analyses and characterization results provided sufficient data to designate Survey Unit 9504-0000 as Class 2 in November 2006.The "Classification Basis Summary" conducted for this survey unit consisted of: a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment (HSA) Supplement," c) Historic and current survey records review, d) Visual inspections and a "walk down." e) Formal or informal interviews with cognizant personnel.

A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" was performed.

Survey Revision 0 3 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Unit 9504-0000 was initially designated as Class 3 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.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 (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".

A review of the 1OCFR50.75 (g) (1) database report identified a few significant radiological events that may have impacted this survey unit.Survey Area 9504 has historically been used to stockpile soils, spoils, snow and other materials.

Packaged radioactive materials have also been stored here over the past few years.In March 1980, Plant Incident Report (PIR) 80-37 reported the discovery of several areas of elevated activity throughout the site, including three (3)discrete sources of elevated activity on the North Parking Lot. The investigation into the incident concluded that the elevated activity was most likely ejected from the Primary Vent Stack as a result of operational events in 1979. In all cases, the areas of elevated activity were removed upon discovery.

In 1997, scoping surveys were performed of the parking lot. Radionuclide specific analysis of soil and some spoil material identified low-level concentrations of Cs-137 with a maximum observed concentration of 9.8E-02 pCi/g. Scanning of the parking lot was conducted using a floor monitor. No additional areas of elevated activity were identified.

Flood control culverts have been installed under the roadway and parking area. These culverts conduct runoff water from the hillside to the east of the survey unit to the west bank of the adjacent pond.A final characterization survey was performed in accordance with SSWP 06-07-005 in October 2006. This survey included biased samples at the outfalls of all culverts.

Two of the soil samples were selected for additional analysis for Hard-to-Detect (HTD) radionuclides.

Cs-137 was positively identified at concentrations greater than MDA but far less than the Operational DCGL. In addition, Sr-90 and Tc-99 were also positively identified (i.e., a result greater than two (2) standard deviations uncertainty) at concentrations greater than 5% of their respective Operational DCGL. Section 5.4.7.2 of the LTP states that radionuclide screening or de-selection is a process where an individual radionuclide or aggregate may be Revision 0 4 Revision 0 4 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD 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.

Subsequently, Sr-90 and Tc-99 were selected as radionuclides of concern in this survey unit. Statistical quantities (mean, median and standard deviation) from the 2006 characterization survey conducted under SSWP 06-07-005 are provided in Table 1.Table 1 -Basic Statistical Quantities for Cs-137, Sr-90 and Tc-99 from the Characterization Survey Cs-137 Sr-90 Tc-99 Prmtr(pCilg) (pCilg) (pCilg)Minimum Value: -7.03E-03 0.OOE+00 0.OOE+00 Maximum Value: 6.84E-01 1.78E-01 1.20E+00 Mean: 1. 12E-01 1.33E-02 1.05E-01 Median: 4.01E-02 0.OOE+00 0.OOE+00 Standard Deviation:

1.83E-01 4.48E-02 3.15E-01 The FSS Engineer performed a visual inspection and walk-down during October 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

Based upon the historical information and the results of radiological surveys performed during characterization, it was concluded that there was a low probability for residual radioactivity to be present in this survey unit in concentrations greater than the Operational DCGLs justifying a final survey unit classification of Class 2 (refer to Section 3).3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning is based on the Data Quality Objective (DQO)process as described by the LTP, Procedure RPM 5.1-11, "Preparation of Final Status Survey Plan, " and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM).

A summary of the main features of the DQO process are provided herein.The DQO process incorporates 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 Revision 0 5 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD criteria.

Rejection of the null hypothesis would satisfy the release criteria objective of the FSS.The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9504-0000 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA)A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity.

This is done through the development of Derived Concentration Guideline Levels (DCGLs). The DCGLs represent the concentration of radioactivity above background, equivalent to a dose-based release criterion and is 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), for existing groundwater radioactivity and for future groundwater radioactivity that will be contributed by building foundations 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 1: HTotal-Hsoil (sediment)

-HExisting GW + HFuture GW The total dose under the LTP criteria is 25 mrem/yr TEDE from all three components.

The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for Connecticut Yankee (CY) is 19 mrem/yr TEDE. To satisfy both the LTP and CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.This survey unit is not affected by existing groundwater (reference CY memo ISC 06-024). Therefore, dose contribution from existing groundwater is 0 mrem/yr TEDE, based on field data.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no concrete foundations or footings remaining within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contributions from future groundwater, the third component are, therefore, 0 mremryr TEDE.Revision 0 6 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Equation 2: 19 mrem/yriotal=

The concentration of residual radioactivity resulting in 19 mrem/yr TEDE is designated as the Operational DCGL (DCGLop), and has been established for the radionuclides of concern as provided in Table 2.Revision 0 7 Revision 0 7 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Table 2 -Radionuclide Specific Base Case Soil DCGLs, Operational DCGLs and Required Minimum Detectable Concentrations (MDCs)Radionuclide (1) Base Case Soil Operational DCGL Required MDC DCGL (pCi/g) (2) (pCi/g) (3) (pCi/g) (4)H-3 4.12E+02 3.13E+02 1.65E+01 C-14 5.66E+00 4.30E+00 2.26E-01 Mn-54 1.74E+01 1.32E+01 6.96E-01 Fe-55 2.74E+04 2.08E+04 1.10E+03 Co-60 3.8 1E+00 2.90E+00 1.52E-01 Ni-63 7.23E+02 5.49E+02 2.89E+01 Sr-90 1.55E+00 1.18E+00 6.20E-02 Nb-94 7.12E+00 5.41E+00 2.85E-01 Tc-99 1.26E+01 9.58E+00 5.04E-01 Ag-108m 7.14E+00 5.43E+00 2.86E-01 Cs-134 4.67E+00 3.55E+00 1.87E-01 Cs-137 7.91E+00 6.01E+00 3.16E-01 Eu-152 1.01E+01 7.68E+00 4.04E-01 Eu- 154 9.29E+00 7.06E+00 3.72E-01 Eu-155 3.92E+02 2.98E+02 1.57E+01 Pu-238 2.96E+01 2.25E+01 1.18E+00 Pu-239/240 2.67E+01 2.03E+O1 1.07E+00 Pu-241 8.70E+02 6.6 1E+02 3.48E+0 1 Am-241 (5) 2.58E+01 1.96E+01 1.03E+00 Cm-243/244 2.90E+01 2.20E+01 1.16E+00 (1)(2)(3)(4)(5)Bold indicates those radionuclides considered to be Hard to Detect (HTD)The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to twenty-five (25) mrem/yr TEDE The Operational DCGL is equivalent to nineteen (19) mrem/yr TEDE The required MDC is equivalent to one (1) mrem/yr TEDE 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 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Characterization was performed in October of 2006 as discussed in Section 2. The characterization survey identified Cs-137, Tc-99 and Sr-90 as the radionuclides of concern.The basic statistical quantities (i.e., mean, standard deviation, median) for Cs-137, Sr-90 and Tc-99 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 dose for soil used for this survey unit to demonstrate compliance with the LTP criteria is nineteen (19) mrem/yr TEDE, as discussed in Section 2 of this Release Record.The DQO process determined that Cs-137, Sr-90 and Tc-99 would be the radionuclides of concern in Survey Unit 9504-0000 (refer to Section 3). Sr-90 and Tc-99 are classified as HTD radionuclides as specified in Table 2. As all soil samples would be subjected to direct analysis for these HTD radionuclides, surrogate DCGLs were not required as part of the survey design for this survey unit. 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.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 Revision 0 9 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD The Sign Test was selected as the non-parametric statistical test to demonstrate that the null hypothesis was rejected.

The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

In addition, this approach is conservative since it includes 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 Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.85 to maintain the relative shift (A/G) in the range of 1 and 3. The resulting 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 Commission (USNRC) for implementation of 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. This indicates that the survey unit has a high probability of rejecting the null hypothesis, assuming that the characterization data are representative of the FSS results. Survey design specified fifteen (15) soil samples for non-parametric statistical testing.The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14,"Identifying, and Marking Surface Sample Locations for Final Status Survey. " Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 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.Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9504-0000-00IF 237577.625 667481.803 9504-0000-002F 237517.152 667516.718 9504-0000-003F 237456.678 667551.632 9504-0000-004F 237456.678 667621.462 Revision 0 10 Revision 0 10 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Table 3 -(continued)

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 additional HTD radionuclide analysis using the Microsoft Excel "RANDBETWEEN" function.

In addition to the analysis already performed for the quantification of Sr-90 and Tc-99, the two selected samples were sent off-site for a full suite analysis of all 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 survey specific quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " included the collection of two (2) soil 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 samples exceeded the 5% requirement.

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 five (5) separate areas. The total surface area to be scanned was approximately 35% of the survey unit. A map of the scan grid locations is provided in Attachment 1.Revision 0 I1I Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 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.Table 4 provides a synopsis of the survey design.Table 4 -Synopsis of the Survey Design (1)Feature Design Criteria Basis Survey Unit 5,645 m 2 Based on AutoCAD-LT and Visual Land Area Sample Plan calculations Type 1 and Type 2 errors were 0.05, Number of 26 sigma was .0772 and the LBGR was set to Measurements (15 systematic grid) 0.85 to maintain Relative Shift in the (11 judgmental) range of 1 and 3, the resultant Relative Shift was 2.0 Grid Spacing 20.61 m Based on triangular grid 6.01 pCi/g Cs-137 Design DCGL 1.18 pCi/g Sr-90 To achieve nineteen (19) mrem/yr TEDE 9.58 pCi/gTc-99 6.01 pCi/g Cs-137 To achieve nineteen (19) mrem/yr TEDE Operational 1.18 pCi/g Sr-90 () to demonstrate compliance with DCGL 9.58 pCi/g Tc-99 Equation 2 of this Release Record Approximately The LTP requires >10% area coverage for Scan Coverage 35% of the area Class 2 survey units Scan Investigation Detectable over Administratively set to achieve nineteen Level background (19) mrem/yr TEDE (1)(1) The allowable dose for soil in this survey unit is nineteen (19) mrem/yr TEDE as the total dose from existing and future groundwater has been established (reference CY memo ISC 06-024)5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0038.

The WP&IR package included a detailed FSSP, job safety analysis, job planning checklist and related procedures for reference.

Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The"Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.Five (5) scan areas were established that constituted approximately 35% of the surface area of Survey Unit 9504-0000.

Grid lines, one meter wide, were painted on the ground of the scan areas. A background survey was performed around the survey unit.Revision 0 12 Revision 0 12 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD 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 35% 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 (HJNP) 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, 9504-0000-004F and 9504-0000-006F, were randomly selected for additional HTD radionuclide analysis.Eleven (11) biased samples, 9504-0000-016J through 9504-0000-026J were collected to be analyzed by the offsite laboratory for gamma spectroscopy.

The judgmental samples were also processed for the HTD radionuclides Sr-90 and Tc-99.The implementation of quality control measures included the collection of two (2) split samples at locations 9504-0000-01 1F and 9504-0000-015F for comparative analysis by the off-site laboratory.

6. SURVEY RESULTS All field survey activities were conducted between November 15, 2006 and November 17, 2006.The sample locations identified in the FSSP 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 off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the fifteen (15) samples taken for non-parametric statistical testing, the associated duplicates and the eleven (11) biased 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).

However, Cs-137 was the only gamma-emitting radionuclide reported in concentrations exceeding the de-selection criteria.The off-site laboratory also processed all fifteen (15) samples and the eleven (11) biased samples for Sr-90 and Tc-99 analyses as well as the two (2)samples for additional 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.Cs-137 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in three (3), Sr-90 was identified in one (1) and Tc-99 in six (6) of the fifteen (15) samples. 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.

In the two (2) samples analyzed for the full suite of HTD radionuclides as specified in the LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 2, two (2) additional HTD radionuclides were positively detected (i.e., a result greater than two (2)standard deviations uncertainty) in more than one sample; however, each of the HTD radionuclides could be de-selected based on the 5% and 10% rules in accordance with LTP Section 5.4.7.2, "Gross Activity DCGLs".Revision 0 15 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Table 7- Summary of Gamma Spectroscopy Results for Surface Soil Samples Comprising the Statistical Sample Population Cs-137 Sr-90 Tc-99 Sample Number pCi/g pCi/g pCi/g 9504-0000-00IF 4.12E-02 -1.12E-02 2.66E-0 1 9504-0000-002F 5.17E-03 -1.63E-02 1.88E-02 9504-0000-003F 1.64E-02 5.94E-03 5.34E-02 9504-0000-004F 7.97E-02 -3.20E-02 2.04E-01 9504-0000-005F 3.37E-03 3.06E-01 4.33E-03 9504-0000-006F 4.69E-03 -8.40E-03 2.55E-03 9504-0000-007F 1.98E-02 -6.95E-03 3.11 E-0 1 9504-0000-008F 0.OOE+00 -1.35E-02 7.96E-02 9504-0000-009F 3.41 E-03 -1.29E-02 3.82E-02 9504-0000-01OF 0.OOE+00 -9.28E-03 2.93E-01 9504-0000-011 F 4.50E-03 -2.49E-02

The samples were 9504-0000-011F/FS and 9504-0000-015F/FS.

The data was evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 and as detailed in HNP Procedure RPM 5.1-24,"Split Sample Assessment for Final Status Survey. " In consideration of the Cs-137, Co-60 and Sr-90 results, guidance for agreement ranges, obtained from USNRC Inspection Procedure 84750, does not address resolution ratios less than four (4); therefore, a determination of acceptability for such rations cannot be made. The acceptance criteria for nuclide identification were not met in sample 9504-0000-011F/FS for the radionuclides of concern.Normally, in such situations, naturally occurring K-40 results are used to determine an acceptable level of agreement.

Aggregate size or distribution of organics can account for such disagreement for K-40. CY Condition Report 06-0223 addresses this issue. The 9504-0000-015F sample set will be used for QC process validation.

There was acceptable agreement between the fields split results at sample location 9504-0000-015F.

The sample analysis vendor, GEL, maintains quality control and quality assurance plans as part of normal operation.

Refer to Attachment 2 for data and data quality analysis results.Revision 0 18 Revision 0 18 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD 8. INVESTIGATIONS AND RESULTS Scan investigation levels were not exceeded for this unit, consequently none were performed.

9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria to be unnecessary and that the remaining residual radioactivity in soil was ALARA.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN No changes were made to the FSS plan 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.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 sample standard deviation was slightly more than the value used for the survey design. This is represented by the shift in the retrospective power curve as shown in Attachment 2g. This would indicate a change to the original LBGR to maintain the number of samples at fifteen (15) to meet the Operational DCGL. However, the value of the LBGR is less of a critical issue as the survey unit has passed the statistical test, and the mean and median values are well below the Operational DCGL when used in conjunction with the unity rule. 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 release criteria with adequate power as required by the DQOs.The basic statistical quantities for the statistical sample population are provided below in Table 10.Revision 0 19 Revision 0 19 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Table 10 -Basic Statistical Quantities the Final Status Survey for Cs-137, Sr-90 and Tc-99 from Cs-137 Sr-90 Tc-99 pCi/g pCi/g pCi/g DCGLop: 6.01E+00 1.18E+00 9.58E+00 Minimum Value: -6.18E-03

2.17E-02 8.39E-02 1.20E-01 The range of the data, about 3.84 standard deviations, was not unusually large. The difference between the mean and median was 37.5% 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 shows some positive skewness as confirmed by the calculated skew of 3.55.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES No anomalies were noted in the performance of this FSS.13. CONCLUSION Survey Unit 9504-0000 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.Revision 0 20 Bypass Road and Secondary Parking Lot SURVEY UNIT 9504-0000 RELEASE RECORD Survey Unit 9504-0000 has met the final DQOs of the FSS plan and has demonstrated compliance with the dose based, unrestricted release criterion.

The sample data passed the Sign Test and the null hypothesis was rejected.The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

The application of Elevated Measurement Comparison, reclassification or remediation of this survey unit was not required.

All identified radionuclides of concern were used for statistical testing to determine the adequacy of the survey unit for FSS.Graphical representation of data indicates some positive skewness that is probably due to localized differences in particulate deposition rates, hydraulic velocity and sedimentation rates. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.

The survey unit was properly designated as a Class 2 survey unit.The dose contribution from soil in this survey unit is 0.40 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey unit is not affected by existing groundwater (reference CY memo ISC 06-024).This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no 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, 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 0.40 mrem/yr Total Effective Dose Equivalent (TEDE).14.
