SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9520-0006 (Southwest Site Storage Area (non-protected area) is designated as Final Status Survey (FSS) Class 1 and consists of approximately nineteen thousand, four hundred and sixty one square feet (19,461 ft2) or one thousand eight hundred eight square meters (1,808 M 2 ) of uninhabited, undeveloped land and is located approximately one thousand eight hundred four feet (1,804 ft) from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1). The survey unit is bounded as follows:

land Survey Unit 9304-0001 to the north (called north as oriented with the north to south flow of the Connecticut River), and land Survey Unit 9522-0001 to the east, south, and to the west. The survey unit is flat and de-vegetated. This is a result of soil grading in support of commodity removal.

The reference coordinates associated with this survey unit are E004 through E006 by S072 through S074 (refer to "HNP License Termination Plan" (LTP)

Section 5.4.4). The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10, "Survey Unit Classification."

The "Classification Basis Summary" conducted for Survey Unit 9520-0006 consisted of:

a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "InitialCharacterizationReport" and the "HistoricSite Assessment Supplement,"

c) Historic and current survey records review, d) Visual inspections and a "walk-down."

A review of the "Initialand Supplemental CharacterizationReports" as well as the previous "Classification Basis Summaries" was performed. Survey Unit 9520-0006 was initially part of Survey Unit 9520-0001, designated as the Southwest Site Storage Area, which was designated as Class 2 during the development of the LTP. The source documents, the "Connecticut Yankee Haddam Neck CharacterizationReport" and "Initial Classificationfor Survey Areas at Connecticut Yankee", were incorporated by reference in LTP revision 0.

Revision 0 3

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD The Southeast Site Storage area had a documented history as a radioactive materials storage area in which at least one (1) case of contamination to underlying soil had been recorded. Examples of some of the major events are provided below.

0 Plant Incident Report (PIR) 80-37 reported the discovery of three (3) discrete sources of elevated activity within the Southeast Site Storage area in of March 1980, along with other areas around the site. The ground level dose rate over one (1) spot was 3 millirem per hour (mr/hr) and, after digging below about one and a half feet (1 1/2 ft) of dirt, the contact reading was reported at about 400 mr/hr. The activity was found above a piece of uncontaminated construction rubble. Isotopic analysis of this discrete source identified Co-60 as the predominate isotope. Subsequent radiological surveys identified an additional discrete source which was also identified as predominately Co-60. Both these locations are believed to be associated with Survey Unit 9520-0001 based on a review of the 1980 survey maps. Records indicate that both elevated areas were removed.

• In 1989, contaminated soil was found along the peninsula access road in both the upper and middle peninsula areas (Areas 9520 and 9530). The soil was subsequently removed, and was determined to have come from the area south of the 115 kV switchyard.

9 In 2006, utilities were being removed as part of the decommissioning effort on the Upper Peninsula which included Survey Areas 9520 and 9530.

Construction debris, including Asbestos Containing Material (ACM) was identified and remediated. In addition to the ACM, two (2) objects were also identified that had detectable radioactivity. The first was a piece of angle iron located in the water utility trench in Survey Area 9530-0004, and the second was a weathered drum containing turbine blades in Survey Area 9520-0002. To further characterize the extent of buried metallic objects, and to identify if any additional drums were present, an Electromagnetic (EM) survey was performed. The survey was conducted in three phases from February 2006 through March 2006 and identified over ninety (90) locations which were then further characterized by test pitting the areas. A total of ninety-four (94) test pits were completed to characterize subsurface materials.

In 2006, surface soil samples were collected to characterize the radiological condition of the surface soils following the decommissioning of buried commodities and systems. Cs-137 was the only gamma emitting radionuclide positively identified in concentrations meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

The statistical quantities (i.e., mean, median and standard deviation) from the characterization are provided in Table 1.

Systematic soil samples were taken in a triangular grid pattern from a random start location. This was combined with a scan survey of 50% of the surface and investigative soil samples at locations exceeding the scan alarm set-point.

Fifteen (15) systematic, four (4) biased and six (6) investigative surface soil samples where taken in Survey Unit 9520-0001. Of the twenty five (25) total samples taken, Cs-137 was positively identified (i.e. a result greater than two (2) standard deviations) in fifteen (15) soil samples. Other radionuclides were also positively identified by gamma spectroscopy and HTD analysis but at concentrations less than the screening criteria. 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% of the Operational DCGL for individual radionuclides and less than 10% of the combined Operational DCGL for aggregates. A summary of the results for the statistical sample population are provided in Table 2.

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD Initial FSS results were documented in the Connecticut Yankee Final Status Survey Final Report - Phase V. Following the completion of FSS, the area was used to stockpile "radiologically clean" rubblized asphalt intended to be used to pave the ISFSI access road after final site grading was complete. In June of 2007, a surveillance survey was performed on the surface soils under the asphalt pile following the removal of the pile. Removal of the pile had removed additional soil below the original grade and exposed additional buried commodities. In addition, two elevated areas were identified at the same location. On-site analysis of soil samples indicated the presence of Co-60 and Cs-137 in sufficient concentrations to warrant remediation and a Class 1 designation for a new survey unit, 9520-0006, which was established around the area of concern that is located within the original boundary of 9520-0001.

Due to the reconfiguration of the survey unit boundaries, the remainder of Survey Unit 9520-0001 was re-subjected to FSS.

In Survey Unit 9520-0006, remediation was performed to remove the discovered buried pipe (broken pieces of vitreous clay piping believed to be part of the original sanitary leech, field that was decommissioned in 1979) and the identified soils exhibiting elevated activity. Following remediation, the area was scanned and six (6) post remediation surface soil samples were taken at the locations exhibiting the highest scan results. The results of the post remediation soil samples were used to design the Final Status Survey. The statistical quantities (i.e., mean, median and standard deviation) are provided in Table 3.

Table 3 - Sample Analysis Results for Post Remediation Soil Samples Cs-137 (pCi/g)

Minimum Value: 6.73E-02 Maximum Value: 1.68E+00 Mean: 4.95E-01 Median: 3.08E-01 Standard Deviation: 6.09E-01 No HTD radionuclides were positively identified (i.e. a result greater than two (2) standard deviations) in the initial FSS soil samples.

The FSS Engineer performed a visual inspection and walk-down during June 2007 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.

Revision 0 6

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD 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 for Survey Unit 9520-0006 (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "Preparationof Final Status Survey Plan," and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM). A summary of the main features of the DQO process are provided herein.

The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis. Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition. The baseline condition is technically known as the null hypothesis. Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection. In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria. Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria. Therefore, the survey unit would satisfy the primary objective of the FSS plan.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9520-0006 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).

A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of DCGLs. The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations.

Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soil (called Base Case Soil DCGL), existing groundwater radioactivity and future groundwater radioactivity that will be contributed by building basements and footings.

The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity. Equation 1 shows the mathematical relationship between the three (3) components and the total dose.

Revision 0 7 Revision 0 7

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD Equation I HTotal =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 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 mrern/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 4.

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Soil samples were collected in 2006 to establish the radiological condition of Survey Unit 9520-0001 for FSS and again in 2007 for post-remediation in Survey Unit 9520-0006. In both cases, Cs-137 was the only gamma emitting radionuclide reported in a concentration with the potential for exceeding the screening criteria. Other radionuclides were positively identified (i.e., a result greater than two (2) standard deviations uncertainty) but at concentrations less than 5% of the Operational DCGL. Subsequently, Cs-137 was selected as the sole isotope of concern for this survey. The radiological survey data that was used for the survey design is provided in Table 3.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans". The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The DQO process determined that Cs-137 would be the sole radionuclide of concern in Survey Unit 9520-0006 (refer to Section 3). The previous characterization and FSS survey data did not identify any HTD radionuclides of concern for this survey unit. Subsequently, surrogate DCGLs were not required for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performance of this FSS would be evaluated to ensure adequate survey design. Radionuclide screening or de-selection is a process where the dose contribution from an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

Revision 0 10

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD As the survey unit is classified as a Class 1 surface soils area, and discrete, elevated areas of contamination was possible, the application of the Elevated Measurement Comparison (EMC) remained an option.

The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. This approach was conservative since it included background Cs-137 as part of the sample set.

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 FinalStatus Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 4.16 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 (10CFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.

The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information, the results of previous Characterization Surveys, the result of the previous FSS and the result of the post-remediation soil samples, the acquisition of additional judgmental surface soil samples from within this survey unit was deemed unnecessary.

The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status' Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 1 area.

Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 5.

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 4.

The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey," included the collection of one (1) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function.

The LTP specifies a required scanning coverage of 100% for outdoor Class 1 areas.

For this Class 1 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under a FSS Plan package.

The 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 9520-0006. Grid lines, one (1) 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 6,470 counts per minute (cpm) up to 8,790 cpm.

The scan area was established and scanned for elevated readings (see Attachment 2 for all scan results). Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with audio response. The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. Approximately 100% of the survey unit was scanned.

Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification. At each sample location, a one (1) meter radius around the sample flag or paint mark was scanned for elevated radiation levels.

Fifteen (15) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design. Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custodyfor FinalStatus Survey Samples."

Two (2) samples (9520-0006-007F and 9520-0006-010F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of one (1) sample (9520-0006-015F) for "split sample" analysis.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing and the associated field split 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.

Cs-137 was identified in eleven (11) of the fifteen (15) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 9.

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 were detected.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. One sample location was selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey". Evaluation using the reported results for Cs-137 resulted in acceptable agreement between the field-split results at the selected location. The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachments 3 and 4 for data and data quality analysis results.

8. INVESTIGATIONS AND RESULTS Although no elevated scan measurements were observed, six (6) additional judgmental surface soil samples were collected at the discretion of FSS supervision during the performance of FSS. These judgmental biased soil samples were analyzed for Cs-137 in accordance with the DQOs used during the survey design. Judgmental sample designations are listed with the GPS coordinates in Table 10.

9. REMEDIATION AND RESULTS Radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to FSS. Remediation was performed to remove buried broken pieces of vitreous clay piping believed to be part of the original sanitary leech field that was decommissioned in 1979 and surrounding soils exhibiting elevated activity. All excavations were characterized and backfilled with "clean" fill prior to performing FSS. In the area where remediation occurred, the ground area is comprised of barren dirt with no vegetation, and the soils have been graded relatively flat to the corresponding elevation of the adjacent survey units. The results for Cs-137 following remediation were well below the Operational DCGL provided in Table 3.

Health Physics TSD BCY-HP-0078, "ALARA Evaluationof 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 2.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). The mean and median values are well below the Operational DCGL. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power.

Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs. The basic statistical quantities for the statistical sample population are provided below in Table 12.

SURVEY UNIT 9520-0006 RELEASE RECORD Table 12 - Basic Statistical Quantities for Cs-137 from the Final Status Survey ICs-137 pCi/g DCGLop: 5.38E+00 Minimum Value: 0.OOE+00 Maximum Value: 6.87E-01 Mean: 1.21E-01 Median: 7.36E-02 Standard Deviation: 1.71E-01 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 and the difference between the mean and median was about 28% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 2.9 for Cs-137. All data, assessments, and graphical representations are provided in Attachment 4.

12. ANOMALIES No anomalies were noted.

13. CONCLUSION Survey Unit 9520-0006 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison was not required.

All identified radionuclides of concern were used for statistical testing to determine the adequacy of the survey unit for FSS.

The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit is properly designated as Class 1.

The dose contribution from soil is 0.38 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.

Revision 0 20

SOUTHWEST SITE STORAGE AREA (NON-PROTECTED AREA)

SURVEY UNIT 9520-0006 RELEASE RECORD This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground foundations or footings 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 2.38 mrem/yr TEDE. Therefore, Survey Unit 9520-0006 is acceptable for unrestricted release.

Cheryl; We're sending 16 samples under MSR 07-0197 to GEL today. All of the samples have a 7 day TAT request. It is acceptable for GEL to use the traced/untraced Tc-99 process for these quick TAT requests. See attached COC for requested analyses.

Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.

h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

• • Indicates analyte is a surrogate compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.

Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.

h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

• • Indicates analyte is a surrogate compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
