The eastern portion of the survey unit contains a small stream that collects water from the hillside to the south and east of the survey unit and flows from south to north through the survey unit until it discharges into the onsite retention pond (Survey Unit 9508-0000).

The reference coordinates associated with this survey unit are E004 through E012 by S050 through S058 (refer to 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 9514-0001 as Class 2 in February 2007.The "Classification Basis Summary" conducted for Survey Unit 9514-0001 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 "walk-down." of the area were performed.

Revision 0 3 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Survey Area 9514, which consists of the Primary Parking Lot, is a surface survey area (the corresponding sub-surface Survey Area is 9803) that has historically been used to stockpile soils, asphalt spoils, snow and other materials.

Containerized radioactive materials have also been stored here over the past few years. The historical assessment of the survey area indicated that the age of the paved area dates back to the earliest days of plant operation.

The scoping report in 1997 had little information on this area, but did note that Plant Incident Report (PIR) 80-37 reported the discovery of several sources of elevated activity in March 1980, along with other areas of the site. The investigation into the incident concluded that the elevated activity was most likely due to radioactive materials ejected from the Primary Vent Stack as a result of operational events in 1979. Isotopic analysis of the particles indicated that the short-lived fission products, Ce- 144 and Ru- 106, dominated the particulate radioactivity.

All elevated areas were removed upon detection according to supplemental reports.A review of the 10 CFR 50.75(g) files identified five (5) additional entries identifying Survey Area 9514 (Survey dated 6/11/79; Contract, drawings and Spec. work logs from 10/11/82; Email from GTS Duratek dated 1/26/99; memo HP 111; memo HP-99-113);

however, these sources did not provide a significant amount of additional information for characterization of Survey Area 9514. Additionally, Warehouse

1. 2 and the Office Building #3/Primary Access Point were constructed in 1989 and the primary parking lot was re-configured.

The primary parking lot was enlarged, re-paved and storm drains installed.

Scanning of the parking lot was conducted on September 17-25, 1997 using a floor monitor. No elevated areas of activity were identified.

Soil samples were taken of a proposed sanitary sewer sump location just west of the Security Building Primary Access Point (PAP). No plant related radioactivity was identified in these samples. Areas behind the Building Maintenance Equipment Warehouse and the Chemical Storage Warehouse were also used as storage areas for radioactive materials returned to site as a result of the Offsite Materials Recovery Program.A storm drain system was installed under the parking area. The storm drain system's purpose was to conduct runoff water from the parking lot, including the northern-most side of Survey Area 9313 (adjacent to the office building and warehouses), and the west hillside primarily to the retention pond. Outfalls from the storm drain system discharge to the southeast and southwest banks of the pond (Survey Area 9508). Overflow from the retention pond discharges to the west bank of the Connecticut River (Survey Area 9512).Recent decommissioning activities included the removal of asphalt, concrete and sub-surface commodities such as storm drain and sewer system piping.Two (2) potential pathways for residual contamination to exist within this survey area are from the mixing of surface soils with paving materials during demolition or from storm drain pipe leakage.Revision 0 4 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD After remediation was complete in Survey Area 9514, characterization samples were collected and analyzed in accordance with Survey and Sampling Work Plan (SSWP) 06-09-001.

Evaluation of soil samples collected for the SSWP provided the information with regard to the radionuclides of concern within Survey Area 9514. These results are summarized in Table 1.Table 1- Basic statistical quantities from SSWP 06-09-001 Radiological Assessment survey Parameter Cs-137 Co-60 Sr-90 (pci/g) (pC00) (pci/g)Operational DCGL: 5.38E+00 2.59E+00 1.05E+00 Minimum Value: -9.68E-03

2.06E-01 2.64E-02 2.18E-02 Characterization sample data indicated that several locations in the eastern portion of Survey Area 9514 contained elevated amounts of Sr-90 at levels up to seven percent (7%) of the Operational Derived Concentration Guideline Level (DCGL) for Sr-90.Based on the characterization results provided in Table 1, Survey Area 9514 was split into two (2) survey units. Survey Unit 9514-0001 (the survey unit covered by this Release Record) is a Class 2 survey unit which consists of open land and comprises the eastern portion of the former primary parking lot.The western portion of the former primary parking lot is covered by Survey Unit 9514-0000, a Class 3 survey unit.The characterization results for Survey Unit 9514-0001 indicate that Cs-137 and Co-60 are the primary radionuclides of concern for this survey unit.Additionally, HTD radionuclide analysis indicated that Sr-90 was present in several samples at levels up to seven percent (7%) of the Operational DCGL.Therefore, Sr-90 was selected as a radionuclide of concern. No other HTD radionuclides were present in concentrations above 5% of the Operational DCGL for soil individually or 10% of the Operational DCGL for soil as a composite.

The FSS Engineer performed a visual inspection and walk-down during February 2007 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

Revision 0 5 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 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 Data Quality Objectives.

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 used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "Preparation of Final Status Survey Plan, " and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM).

A summary of the main features of the DQO process are provided herein.The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis.

Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition.

The baseline condition is technically known as the null hypothesis.

Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection.

In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria.

Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria.

Therefore, the survey unit does satisfy the primary objective of the Final Status Survey Plan (FSSP). Probabilistic sampling is a preferred method to select a sample so that each item in the population being studied has a known likelihood of being included in the sample. Probabilistic sampling may include simple random sampling where every sample has the same chance of being included, or systematic random sampling where samples are arranged in some order and a random starting point is selected.The primary objective of the FSSP was to demonstrate that the level of residual radioactivity in Survey Unit 9514-0001 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.Revision 0 6 Revision 0 6 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity.

Equation 1 shows the mathematical relationship between the three (3) components and the total dose.Equation I HTotal =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/yrFuturcGW 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 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Table 2 -Radionuclide Specific Base Case Soil DCGL, Operational DCGLs and Rpnauired Minimum Detectahle Radionuclide (1) Base Case Soil Operational DCGL Required MDC DCGL (pCi/g) (2) (pCi/g) (3) (pCi/g) (4)H-3 4.12E+02 2.81E+02 1.65E+01 C-14 5.66E+00 3.84E+00 2.26E-01 Mn-54 1.74E+01 1.18E+O1 6.96E-01 Fe-55 2.74E+04 1.87E+04 1.1OE+03 Co-60 3.81E+00 2.59E+00 1.52E-01 Ni-63 7.23E+02 4.91E+02 2.89E+01 Sr-90 1.55E+00 1.05E+00 6.20E-02 Nb-94 7.12E+00 4.85E+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 Pu-241 8.70E+02 5.92E+02 3.48E+01 Am-241(5) 2.58E+01 1.75E+01 1.03E+00 Cm-243/244 2.90E+01 1.97E+01 1.16E+00 k1) Bod inuicates mHose rauionucliues consiuereu to be ham LO ueeCLL.(2) 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.(3) The Operational DCGL is equivalent to seventeen (17) mrem/yr TEDE.(4) The required MDC is equivalent to 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.

Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Fifteen (15) samples were collected and analyzed during characterization, as discussed in Section 2.The mean and variability of Cs-137, Co-60 and Sr-90 in soil in this survey unit was determined during characterization 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 Revision 0 8 Revision 0 8 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD 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 FSSP uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.Characterization sampling was used to determine concentration variability.

The DQO process determined that Cs-137, Co-60 and Sr-90 would be the radionuclides of concern in survey unit 9514-0001 (refer to Section 3). The sum of fractions or unity rule was used with the individual Operational DCGLs because multiple radionuclides (Cs-137, Co-60 and Sr-90) are considered in the survey design. Other radionuclides identified during FSS were evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of adjacent areas and via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 2 area and discrete, elevated areas of contamination were not expected.The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

This approach was conservative since it included background Cs-137 as part of the sample set.The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.91 to maintain the relative shift (A/a) in the range of 1 and 3. The resulting Adjusted Relative Shift was 2.0. A Prospective Power Curve was generated using COMPASS, a software package Revision 0 9 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.Survey design specified fifteen (15) surface soil samples for non-parametric statistical testing.The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 2 area.Judgmental sampling was included as a feature of this survey design to investigate suspect areas and account for any anomalies identified in the field.Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a Global Positioning System (GPS) to locate sample points in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Revision 0 10 Revision 0 10 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Table 3 -Sample Measurement Locations identified for Non-parametric Statistical Testin2 with their Associated GPS Coordinates Designation")

Although Procedure RPM 5.1-11 only specified that 5% of the samples are required to be selected for HTD analysis, two (2) soil samples or 13% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RANDBETWEEN" function.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12,"Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 2.The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey," included the collection of two (2) soil samples for "split sample" analysis by the off-site laboratory.

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

The number of quality control soil samples was determined to be 13% of fifteen (15) samples.The LTP specifies that scanning will be performed along with a combination of systematic and judgmental measurements (samples) for a Class 2 land area and should cover 10% to 100% of the area. The fraction of scanning coverage was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS.Revision 0 I1I Revision 0 11 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Based on the historical site assessment and the characterization data available, it was determined that three (3) separate scan grids needed to be established.

The total surface area to be scanned was approximately 25% of the 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.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under a detailed FSSP 9514-0001 that included the implementation of a 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 9514-0001.

Grid lines, one (1) meter wide, were Revision 0 12 Revision 0 12 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD painted on the ground of each of the three (3) scan areas. A background survey was performed around the survey unit and it was determined that the range of background measurements, using a Eberline E-600 with a SPA-3 sodium iodide detector, was varied from 4,000 counts per minute (cpm) in the western part of the survey unit up to 9,000 cpm near the southeastern part of the survey unit toward the hillside.The scan areas were established and each area was 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 fixed measurement locations were identified and marked with a surveyor's flag or paint for identification.

At each sample fixed measurement location, a one (1) meter radius around the sample flag or paint mark was scanned for elevated radiation levels.One (1) of the original fifteen (15) samples identified, 9514-0001-008F was not collected because the sample location was found to be inaccessible.

Additionally, the sample location could not be identified within 3 meters of the original location.

As part of the survey design, several additional alternate sample locations were selected randomly, as determined by using Visual Sample Plan (VSP), in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." One (1) of the random sample locations was selected and designated as 9514-0001-016F.

Fifteen (15) surface soil samples were collected for non-parametric statistical testing 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 (9514-0001-001F and 9514-0001-010F) were randomly selected for HTD radionuclide analysis.The implementation of survey specific quality control measures included the collection of two (2) samples (9514-0001-001F and 9514-0001-013F) for "split sample" analysis.Follow-up sampling was conducted at each of the elevated measurement locations.

1.6. SURVEY

RESULTS All field survey activities were conducted between February 22 and February 27, 2007.On February 22, 2007, three (3) scan areas, that comprised approximately 25%of the total surface area for the survey unit, were scanned for elevated radiation levels.Six (6) elevated measurement locations within scan area three (3) were identified during scanning.

Each of the locations was evaluated using the Exploranium, and were determined to be Naturally Occurring Radioactive Material (NORM) based on the presence of loose rock. Table 5 provides an overview of the scan area survey. Attachment 1 contains a map that identifies the locations of the three (3) scan grids.

One (1) of the original fifteen (15) samples established by VSP using a random start, systematic triangular grid pattern, was deemed not accessible and was therefore replaced by a random sample location that was also identified by VSP. Sample number 9514-0001-008F was replaced by sample number 9514-0001-016F.

Additionally, on February 26, 2007, six (6) investigative samples were collected at the elevated measurement locations identified by the scan surveys and were designated as 9514-0001-024F, 9514-0001-025F, 9514-0001-026F, 9514-0001-027F, 9514-0001-028F and 9514-0001-029F.

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated duplicates, the five (5) biased samples and the six (6) 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 (2) standard deviations uncertainty).

Cs-137 was identified in thirteen (13) of the fifteen (15) samples collected for non-parametric statistical testing. Co-60 was not identified in any of the fifteen (15) samples collected for non-parametric statistical testing. Sr-90 was identified in five (5) of the fifteen (15) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results for the samples indicated that Cs-137 was present at levels that are similar to 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 "sum-of-fractions" or "unity rule" is the mathematical test used to evaluate compliance with radiological criteria for license termination when more than one radionuclide has been determined to be potentially present. The combination of the fractions of each detected radionuclide against their respective Operational DCGL must be less than or equal to one (1).The unity rule is: Equation 3 Ci C 2 C,-÷++ C2 -- <1 DCGLI DCGL 2 DCGL, Where: Cn = concentration of radionuclide n and DCGLn = DCGL of radionuclide n.The results of the unity rule calculation for the radionuclides of concern in the statistical sample population for Survey Unit 9514-0001 are provided in Table 7.Revision 0 18 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Table 7- Summarv of Soil SamDle Results Fraction of Sample Number Cs-137 Co-60 Sr-90 the pCi/g pCi/g pCi/g Operational DCGL (1)9514-0001-OOIF 2.71E-02 2.88E-03 -8.87E-04 0.005 9514-0001-002F 6.23E-02 7.82E-03 -2.05E-02

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. No HTD radionuclides, other than Sr-90, met the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

Additionally, all HTD radionuclide, other than Sr-90, met 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.

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

Two (2) samples or thirteen percent (13%), of the fifteen (15) total samples collected for non-parametric statistical testing were selected for split sample 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." Split samples 9514-0001-004F/FS were assessed and it was determined that there were low resolution ratios (<4) for both Cs-137 and Co-60. The agreement Revision 0 19 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD range could not be established because NRC Inspection Procedure 84750 does not address resolution ratios below 4. Therefore, a determination of the acceptability for such low rations cannot be made. However, Potassium-40 (K-40) was found to be present at an acceptable level of agreement.

Therefore, no further action was warranted.

Split samples 9514-0001-010F/FS were assessed and it was determined that there was an acceptable level of agreement for Cs-137. Therefore, no further action was warranted.

Due to the extremely low levels of Co-60 reported the same situation was exhibited as was observed for split sample numbers 9514-0001-004F/FS.

The sample analysis vendor, General Engineering Laboratories, LLC, Charleston, South Carolina, maintains quality control and quality assurance plans as part of normal operation.

Refer to Attachment 3 and Attachment 4 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS Five (5) biased samples were collected at locations along the creek bottom that runs south to north along the eastern edge of the survey unit.Six (6) investigative samples were collected at elevated scan locations throughout the survey unit.Gamma spectroscopy and Sr-90 analyses was performed by the off-site laboratory to the required MDC. None of the samples exceeded 19% of the Operational DCGL. No further action or investigations were required (see Table 8).Table 8- Judgmental and Investigative Sample Results Fraction of the Sample Number (2) Cs-137 Co-60 Sr-90 Oprtoa pCi/g pCi/g pCi/g Operational DCGL(" 9514-0001-024F

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 Sample location number 9514-0001-008F was deemed inaccessible and was replaced by sample location number 9514-0001-016F.

None other changes to the FSSP were made.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 standard deviation was slightly less than the value used for the survey design. This would indicate that the number of samples collected was sufficient to meet the Operational DCGL. 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 unrestricted release criteria with adequate power as required by the DQOs.For Cs-137, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected.

The difference between the mean and median was 32% 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 a positive skewness as confirmed by the calculated skew of 3.02.Revision 0 21 Revision 0 21 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD Since Co-60 was not identified (i.e., a result greater than two (2) standard deviations uncertainty) in any of the fifteen (15) samples collected for non-parametric statistical testing, the data was not used to determine the adequacy of statistical testing for this survey unit.For Sr-90, the range of the data, about three (3) standard deviations, was not a particularly large variation considering that the levels were at extremely low levels where such variation is to be expected.

The difference between the mean and median was 36.7% of the standard deviation which indicates a small skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot shows a slightly positive skew as confirmed by the calculated skew of 0.367.All data, assessments, and graphical representations are provided in Attachment 3 and Attachment 4.12. ANOMALIES The anomalies associated with the disagreement between the field splits was presented in Section 7. The source of the disagreement for Co-60 is likely due to extremely low levels of activity being reported and the statistical uncertainties associated with the comparison of very small numbers. Standard statistical tests, ratio comparisons and skew, may not provide the same information at extremely low numbers as compared to higher numbers.No other anomalies were noted.13. CONCLUSION Survey Unit 9514-0001 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.Cs-137 and Sr-90 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 1.43 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is two (2)mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no buried concrete foundations and footings containing residual radioactive material within the groundwater saturated zone Revision 0 22 Revision 0 22 EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD 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 3.43 mrem/yr Total Effective Dose Equivalent (TEDE). Therefore, Survey Unit 9514-0001 is acceptable for unrestricted release.14.

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.ill EAST PRIMARY PARKING LOT SURVEY UNIT 9514-0001 RELEASE RECORD ATTACHMENT 4 (DQA RESULTS)
