The survey unit is bounded by Survey Unit 9520-0003.

The survey unit is relatively level open space in the middle of the peninsula.

The restoration of the peninsula for FSS has removed most of the surface interference in the survey unit.The reference coordinates associated with this survey unit are E005 through EO1 1 by S086 through S091 (refer to License Termination Plan (LTP) Section 5.4.4). The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification.

" The "Classification Basis Summary" conducted for Survey Unit 9520-0004 consisted of: a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walkdown." A review of the 1OCFR50.75(g)(1) database report and historical files shows a documented history of the use of this survey unit as a radioactive materials storage area. Examples of some of the major events are provided below.a) Plant Incident Report (PIR) 80-37 reported the discovery of three (3)discrete sources of elevated activity on the Southeast Site Storage area in March 1980, along with other areas around the site. The three (3)discrete sources were identified within adjacent Survey Units 9520-0001 and 9520-0002.

The elevated areas were removed upon detection according to the report.b) Health Physics surveys performed in 1983 and 1985 document the discovery of radioactive material (strainers, bolts, wood pallets, sections of pipe, etc.) on the peninsula.

The 1985 survey documents the discovery of contaminated dirt under a pallet.Revision 0 3 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD c) Condition Report (CR) 05-0314: Documents the discovery of excavation spoils, intended for backfill, above the radiological criteria for use as backfill.

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

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

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

Survey Unit 9520-0004 was initially included in Survey Unit 9520-0003, a Class 2 survey unit. However, in March of 2006, Co-60 and Cs-137 were identified in subsurface soils in sufficient quantities to warrant radiological remediation.

Radiological remediation was performed in July 2006. A new Class I survey unit, Survey Unit 9520-0004, was established to bound the area of remediation.

Characterization was performed in August 2006 to support final classification and FSS planning.

Statistical quantities (mean, median and standard deviation) from the 2006 characterization survey conducted under SSWP 06-07-006 are provided in Table 1.Table I Basic Statisticn centr ation( :. -.!S u rN ey Minimum ObservedCocnrto(pig:I 8E0-v.Maximum Observed Concentration (pCi/g): 4.80E-04 Mean (pCi/g): 1.62E-01 Median (pCi/g): 6.12E-02 Standard Deviation (pCi/g): 5.88E-02 The FSS Engineer performed a visual inspection and walk-down during September 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

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

Based upon the identification of radioactive material above the Derived Concentration Guideline Levels (DCGLs), and the need for radiological remediation, it was concluded that there was some probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class 1 (refer to Section 3).Revision 0 4 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD 3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "Preparation of Final Status Survey Plan, " and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM).

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

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

The baseline condition is technically known as the null hypothesis.

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

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

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

Therefore, the survey unit does satisfy the primary objective of the FSS plan.The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9520-0004 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.Equation 1 HTota =Hsoi- HExistingGW

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

The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation Revision 0 5 Revision 0 5 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD standard for CY is nineteen (19) mrem/yr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.This survey area is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is bounded by two (2) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no buried concrete foundations or footings containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component is, therefore, zero (0) mrem/yr TEDE.Equation 2 19 mrem/yrTotal

= 17 mrem/yrsoil

+ 2 mrem/yrExisting GW+ 0 mrem/yrFutureGW The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.1t-3 4.1 ZIL,+/-U2 2.ZOl?+SU 1.65E+01 C-14 5.66E+00 3.85E+00 2.26E-01 Mn-54 1.74E+01 1. 1 8E+01 6.96E-01 Fe-55 2.74E+04 1.86E+04 1.1 OE+03 Co-60 3.81 E+00 2.59E+00 1.52E-01 Ni-63 7.23 E+02 4.92E+02 2.89E+O1 Sr-90 1.55E+00 1.05E+00 6.20E-02 Nb-94 7.12E+00 4.84E+00 2.85E-01 Tc-99 1.26E+01 8.57E+00 5.04E-01 Ag-108m 7.14E+00 4.86E+00 2.86E-01 Cs-134 4.67E+00 3.18E+00 1.87E-01 Cs-137 7.91E+00 5.38E+00 3.16E-01 Eu-152 1.01E+01 6.87E+00 4.04E-0 i Eu- 154 9.29E+00 6.32E+00 3.72E-01 Eu- 155 3.92E+02 2.67E+02 1.57E+01 Revision 0 6 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD Pu-239/240 2.67E+O 1 1.82E+01 1.07E+00 Pu-241 8.70E+02 5.92E+02 3.48E+O1 Am-241 (5) 2.58E+01 1.75E+01 1.03E+00 Cm-243/244 2.90E+O1 1.97E+O1 1.16E+00 (1) Bold indicates those radionuclides considered to be Hard-to-Detect (HTD)(2) The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to 25 mrem/yr TEDE (3) The Operational DCGL is equivalent to 17 mrem/yr TEDE (4) The required MDC is equivalent to I mrem/yr TEDE (5) Americium-241 can be analyzed by gamma and alpha spectroscopy and is considered to be Easy to Detect (ETD); the preferred result is the alpha spectroscopy's when both analyses are performed Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Soil samples were collected in 2006 to establish the radiological condition of Survey Unit 9520-0004 for FSS. Cs-137 was the only gamma emitting radionuclide reported in concentrations with the potential for exceeding the screening criteria.

The characterization data were used for the survey design and are provided in Table 1.Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans". The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.Revision 0 7 Revision 0 7 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD The DQO process determined that Cs-137 would be the radionuclide of concern in Survey Unit 9520-0004 (refer to Section 3). Other radionuclides identified during this FSS would be evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit based the previous FSS of this survey unit and via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did apply to this survey unit since it is a Class 1 area and discrete, elevated areas of contamination were 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 5.27 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting Adjusted Relative Shift was 2.0. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing.The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1 14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 1 area.Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Revision 0 8 Revision 0 8 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD' Table 3 -Sample Measuremnent Locationis iNith Asso~ciated GP-S Coordinates Designaiti n Northiing Fasting 9520-0004-OOIF 235584.13 669733.34 9520-0004-002F 235619.22 669753.61 9520-0004-003F 235654.32 669773.87 9520-0004-004F 235619.22 669794.13 9520-0004-005F 235584.13 669773.87 9520-0004-006F 235549.03 669753.61 9520-0004-007F 235549.03 669794.13 9520-0004-008F 235584.13 669814.39 9520-0004-009F 235619.22 669834.65 9520-0004-01 OF 235584.13 669854.91 9520-0004-01 IF 235549.03 669834.65 9520-0004-012F 235513.94 669814.39 9520-0004-013F 235513.94 669854.91 9520-0004-014F 235549.03 669875.18 9520-0004-015F 235584.13 669895.44 Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis.

Two (2) soil samples, or about 10% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel"RANDBETWEEN" function.

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

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

The number of quality control soil samples was about 10% of fifteen (15) samples.The LTP specifies a required scanning coverage of 100% for outdoor Class 1 areas.Revision 0 9 Revision 0 9 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD For this Class 1 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8.

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

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

Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The "Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 9520-0004.

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 4,950 counts per minute (cpm) up to 7,230 cpm.Revision 0 10 Revision 0 10 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD The scan area was established and scanned for elevated readings (see Attachment 2 for all scan results).

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

The E-600 was operated in the rate-meter mode and used with audio response.

The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. Approximately 100% of the survey unit was scanned.Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification.

At each sample location, a one (1) meter radius around the sample flag or paint mark was scanned for elevated radiation levels.Seventeen (17) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design. Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples." Two (2) samples (9520-0004-011F and 9520-0004-014F) were randomly selected for HTD radionuclide analysis.The implementation of survey specific quality control measures included the collection of two (2) samples (9520-0004-004F and 9520-0004-012F) for "split sample" analysis.6. SURVEY RESULTS All field survey activities were conducted between October 13, 2006 and October 23, 2006.Table 5 provides an overview of the scan results for sample measurement locations.

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field splits, and the two (2) confirmatory samples using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDCs. Gamma spectroscopy results identified some radionuclides meeting the accepted criteria Revision 0 12 Revision 0 12 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD for detection (i.e., a result greater than two standard deviations uncertainty).

However, Cs-137 was the only radionuclide reported in concentrations exceeding the de-selection criteria.Cs-137 was identified in thirteen (13) of the fifteen (15) samples collected for non-parametric statistical testing. Cs-137 was the primary radionuclide confirming the DQOs. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentration of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC.Revision 0 13 Revision 0 13 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD 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.

H-3 was the only HTD, which by analysis, met the criteria for detection (i.e., a result greater than two standard deviations uncertainty).

The highest result for H-3 was at 4% of the Operational DCGL.9520-0004-014F 9.45E+00 0.034 (1) The Operational DCGL from Table 2 is 280 pCi/g for H-3 to achieve 17 mrem/yr TEDE 7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis.

Ten percent (10%) of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey". Cs-137 was not detected in sufficient quantities in the field split results at location 9520-0004-004 to evaluate in accordance with procedure.

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

There was acceptable agreement between the field split results at location 9520-0004-012.

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 Two confirmatory samples were collected at the locations exhibiting elevated scan readings.

REMEDIATION AND RESULTS Radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to FSS. The results for Cs-137 following remediation were well below the Operational DCGL provided in Table 2.Cs-137 was not identified in any of the samples. 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 No changes were made to the FSS plan.11. DATA QUALITY ASSESSMENT (DQA)The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment, " for completeness and consistency.

The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 1.The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation).

The mean and median values are well below the Operational DCGL. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power.Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.For Cs- 137, the range of the data, about five (5) standard deviations, was not an overly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected.

The difference between the mean and median was about 20% of the standard deviation which indicates slight skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 0.88.All data, assessments, and graphical representations are provided in Attachment 4.12. ANOMALIES No anomalies were noted.Revision 0 15 Revision 0 15 SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9520-0004 RELEASE RECORD 13. CONCLUSION Survey Unit 9520-0004 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved following remedial action. Elevated Measurement Comparison was not required.Cs-137 was used for statistical testing to determine the adequacy of the survey unit for FSS.The sample data passed the Sign Test. The null hypothesis was rejected.

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

The survey unit is properly designated as Class 1.The dose contribution from soil is less than 1 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024); therefore, the dose contribution from future groundwater is zero (0) mrem/yr TEDE.The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity, will not exceed 3 mrem/yr TEDE. Therefore, Survey Unit 9520-0004 is acceptable for unrestricted release.14.
