ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9539-0001, which encompasses the northern portion of the access road to the Independent Spent Fuel Storage Installation (ISFSI) and the Southeast Landfill Area is designated as Final Status Survey (FSS) Class 2 and consists of approximately nine thousand three hundred thirty-two (9,332) square meters of open land and is located approximately one thousand, three hundred forty-four (1,344) feet from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1).

The survey unit is an open land area located along the east shore of the Discharge Canal from the non-protected area southeast grounds of the site to the ISFSI vehicle barrier.

The survey area is a narrow strip of land encompassing the access road and 25 feet on both sides of the road. A minimal amount of brush and trees remain in the survey area. The area topography consists. mostly of steep, rocky or vegetated hillsides. A majority of the trees have been cleared for the construction of the access road. The ISFSI access or "Haul" road crosses north to south through this survey unit.

The survey unit is bounded as follows: land Survey Unit 9522-0001 to the north (called north as oriented with the north to south flow of the Connecticut River),

the Discharge Canal to the west, land Survey Unit 9539-0002 to the south, and land Survey Unit 9532 to the east.

Work activities to support the ISFSI access road construction have occurred in this survey unit. These activities included tree and stump removal, silt fence installation, soil removal, grading and rock blasting. Hillsides grading left some locations showing a steeper incline. Rock shelves and outcroppings were located along the hillside, especially in the east and south. There are occasional voids along the access road where the grading process has stripped away underlying rock.

The reference coordinates associated with this survey unit are E009 through E014 by S081 through S096 (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 9539-0001 consisted of:

a) A review of the 10CFR50.75 (g) (1) database, Revision 0 3

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD 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."

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

Survey Area 9539 was previously designated as Survey Area 9528. Survey Unit 9539-0001 is the northern portion of Survey Area 9539 and includes the former Survey Unit 9528-0002 and a portion of 9528-0003. Survey Area 9528 was initially designated as Class 3 during the development of the LTP.

The source documents, the "Connecticut Yankee Haddam Neck Characterization Report" and "Initial Classification for Survey Areas at Connecticut Yankee", were incorporated by reference in LTP revision 0.

The second source document justified a Class 2 designation for those areas for which there was historical evidence of contamination above the Derived Concentration Guideline Levels (DCGL), but for which recent surveys had shown that decontamination efforts had occurred and that the radiological conditions were expected to be below the DCGLs. Additional justification for a Class 2 designation based on survey and sampling data was provided as another reference to the LTP by the "Haddam Neck Plant Historical Site Assessment Supplement".

The historical documents (e.g., the 10CFR50.75(g)(1) files) identify a number of events that may have impacted this survey unit.

In the past, the public was granted access to this area for recreational purposes (e.g. hiking). Typical debris and litter (soda bottles, fishing line, etc.) were found in the area. From time to time, 55-gallon drum trash containers were positioned along the Canal Road to.

collect and control litter.

In December of 2001, scan surveys in an area along the road indicated the possible deposition of radioactive material in an unauthorized location (CR 01-0490). In March of 2002, investigative soil sampling was performed in the area where elevated scan results were observed. The soil sample results identified low-level plant-related radioactive material (Co-60). The presence of Co-60 was not expected as this area was previously identified as Survey Unit 9528-000, a Class 3 area (CR 02-0125).

Although measurement results were very low relative to the DCGL, soil containing the Cobalt-60 were removed from the area as a prudent measure.

Approximately twenty-five (25) cubic meters of soil was removed for disposal as waste.

Post excavation soil sample analyses results did not identify any remaining residual activity.

Based on the findings of the survey and the subsequent remediation, Survey Unit 9528-0000 was reclassified as a Class 2 open land area. In accordance with the survey unit size limitations in the License Termination Plan (LTP), Survey Unit 9528-0000 was subdivided into three (3) new survey units designated as 9528-0002, 9528-0003 and 9528-0004.

Revision 0 4

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD Low-level licensed material from the plant and the Offsite Material Recovery Program (OMRP) utilized the canal roads as a route to the Southeast Landfill and Material Storage areas. Sample data associated with the OMRP identified two (2) Hard-to-Detect (HTD) radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

However, the reported concentrations of Ni-63 and Fe-55 were a very low fraction of the applicable Base Case Derived Concentration Guideline Level (DCGL) for soil (<1%). Other radionuclides were not expected to be present in any significant percentage of their DCGL.

In July of 2002, Survey Units 9528-0002, 9528-0003 and 9528-0004 were subjected to FSS under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0002-00104-000.

FSS consisted of surface soil samples and scan measurements. Scan surveys were performed with an Eberline E-600 using a SPA-3, 2"x2" sodium iodide detector.

Fifteen (15) surface soil samples were collected from each of the three (3) survey units contained within Survey Area 9528. During scanning, several areas were identified with slightly elevated readings, which prompted the collection of additional investigation soil samples,from these areas.

All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory.. -Nine (9) of the forty-nine (49) total samples collected were analyzed for "Hard-to-Detect" (HTD) radionuclides. Cs-137 and Co-60 were the primary radionuclides detected in the sample population. No HTD radionuclides were positively identified.

FSS results from 2002 demonstrated that all three (3) survey units were acceptable for unrestricted release. The sample analysis results from the 2002 FSS survey are provided in Table 1.

The asphalt was a byproduct of demolition activities in various areas of the site. The material had been stock-piled awaiting disposal. Prior to introducing the material into the survey area, volumetric samples were taken and analyzed by gamma spectroscopy.

Low levels of Cs-137 and Co-60 were detected. However, as the origin of the material was from impacted areas and the volumetric samples were not completely Revision 0 5

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD representative of all the material that was deposited, the previously performed FSS in Survey Area 9528 was invalidated. Survey Area 9528 was subsequently renamed as Survey Area 9539 to support the resurvey.

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 a review of the historical information and the results of the Characterization Survey data, it was concluded that there was a low probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class 2 (refer to Section 3).

3.

DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "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 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 9539-0001 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

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 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 1 HTotal =Hsoil + HExistingGW + HFutureG W The total dose under the LTP criteria is twenty-five (25) mremlyr 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.

CY memo ISC 06-024 addresses the impact of existing and future groundwater on specific survey areas at CY. Survey Area 9539 is not specifically addressed by this reference. However, CY memo ISC 06-024 does state that Survey Area 9528 is affected by existing groundwater and is not considered impacted by future groundwater radioactive contamination, as there are no concrete foundations or footings remaining, within the groundwater saturated zone in the area.

Since Survey Area 9528 became Survey Area 9539, the dose contribution from existing and future groundwater will impact Survey Area 9539 in the same manner as it did Survey Area 9528.

Therefore the dose contribution from existing groundwater in Survey Unit 9539 is bounded by two (2) mrem/yr TEDE and the dose contribution from future groundwater, the third dose component, is zero (0) mremlyr TEDE.

Equation 2 19 mrem/yrTotal = 17 mrem/yrsoil + 2 mremnyrExisting 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 (DCGLop), and has been established for the radionuclides of concern as provided in Table 2.

Revision 0 8

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Soil samples were collected in 2002 as part of the previous FSS to establish the radiological condition of Survey Unit 9539-0001.

Cs-137 and Co-60 were the only two (2) gamma emitting radionuclides reported in concentrations with the potential for exceeding the screening criteria. No HTD radionuclides were positively identified. The previous FSS data were used for this survey design and are provided in Table 1.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL.

Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS.

Sample report summaries included unique sample identification, analytical

method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4.

SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards.

Guidance for preparing FSS plans is provided in Procedure RPM 5. 1-11, "Preparation of Final Status Survey Plans".

The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The DQO process determined that both Cs-137 and Co-60 would be the radionuclides of concern in Survey Unit 9539-0001 (refer to Section 3).

The characterization survey did not identify any HTD radionuclides of concern for this survey unit.

Subsequently, surrogate DCGLs were not required for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs".

Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performance of this FSS would be evaluated to ensure adequate survey design.

Radionuclide screening or de-selection is a process where the dose contribution from an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 2 area and discrete, elevated areas of contamination were not expected.

Revision 0 9

ISFSI HAUL ROAD (NORTHERN SECTION)

SURVEY UNIT 9539-0001 RELEASE RECORD The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

This approach was conservative since it included background Cs-137 as part of the sample set.

The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "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 0.8 to maintain the relative shift (A/a) in the range of 1 and 3. The resulting relative shift was 2.00. 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 (IOCFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing.

Based upon a review of the historical information and Characterization Survey data, the acquisition of additional judgmental surface soil samples from within this survey unit was deemed unnecessary.

The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 2 area.

Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.

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 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 10% to 100% for outdoor Class 2 areas. The fraction of scanning coverage was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS. Based on the historical site assessment, the characterization data available, and the use of this survey unit, it was determined that scanning was required in six (6) separate areas. 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. Table 4 provides a synopsis of the survey design.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0048.

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.

Six (6) scan areas were established that constituted approximately 25% of the surface area of Survey Unit 9539-0001. Grid lines, one meter wide, were painted on the ground of the scan area. A background survey was performed around the survey unit and it was determined that, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 4,290 counts per minute (cpm) up to 9,620 cpm.

The scan areas were established and scanned for elevated readings (see 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 Revision 0 12

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 1or 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 (9539-0001-OOIF and 9539-0001-007F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of one (1) sample (9539-0001-003F) for "split sample" analysis.

6.

SURVEY RESULTS All field survey activities were conducted between January 3, 2007 and January 9, 2007.

The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan results for sample measurement locations. Scan results for the entire survey unit are provided in Attachment 2.

T he action level is based on a measurement above ambient background in accordance with the FSS plan The FSS plan requires movement of the sample measurement location to the area within the 1 meter radius yielding the response above the action level. Sample locations 9539-0001-006F and 9539-0001-014F were moved accordingly.

The scan areas, that comprised approximately 25% of the total surface area for the survey unit, were scanned for elevated radiation levels.

The areas were scanned in accordance with the FSS plan on January 4, 2007 through January 9, 2007. Several elevated measurement locations were identified during scanning.

Table 6 provides an overview of the scan area survey. Complete scan results are provided in Attachment 2.

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field split and the six (6) investigation samples using gamma spectroscopy.

Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

However, Cs-137 and Co-60 were the only gamma-emitting radionuclides reported in concentrations exceeding the de-selection criteria.

Cs-137 was identified in ten (10) and Co-60 was identified in two (2) of the fifteen (15) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 7.

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.

Tc-99 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in one (1) of the two (2) samples analyzed for HTD radionuclides. In accordance with LTP Section 5.4.7.2, "Gross Activity DCGLs",

the criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates.

For Tc-99, the Operational DCGL is 8.57 pCi/g to achieve a TEDE of seventeen (17) mrem!yr. The positive analytical result for Tc-99 equated to 4.5% of the Operational DCGL. Subsequently, Tc-99 was deselected as a radionuclide of concern for this survey unit.

QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. One (1) sample location was selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey".

There was acceptable agreement between the field split results at location 9539-0001 -003F.

The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation. Refer to for data and data quality analysis results.

REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

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 10.

The difference between the mean and median was about 41% of the standard deviation which indicates some skewness in the data.

The data was represented graphically through postinig plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 0.91 for Cs-137.

SURVEY UNIT 9539-0001 RELEASE RECORD Co-60, although included in the FSS plan for compliance purposes, was positively identified in only two (2) of the fifteen (15) samples collected for non-parametric statistical testing. Assessment of the basic statistical quantities and graphical representation of Co-60 was not considered useful giyen the limited number of data points to represent the distribution.

All

data, assessments, and graphical representations are provided in.

ANOMALIES No anomalies were noted.

13.

CONCLUSION Survey Unit 9539-0001 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison and remediation was not required.

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

The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit is properly designated as Class 2.

The dose contribution from soil is 0.276 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 2.276 mremnyr TEDE.

Therefore, Survey Unit 9539-0001 is acceptable for unrestricted release.

Range Anist Date Time Notes:

The Qualifiers in this report are defined as follows:

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

The TIC is a suspected aldol-condensation product B

Target analyte was detected in the associated blank BD Results are either below the MDC or tracer recovery is low C

Analyte has been confirmed by GC/MS analysis D

Results are reported from a diluted aliquot of the sample H

Analytical holding time was exceeded J

Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the detection limit R

Sample results are rejected U

Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

UI Gamma Spectroscopy--Uncertain identification X

Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y

QC Samples were not spiked with this compound A

RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL h

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

• • Indicates analyte is a surrogate compound.

^ 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.
