SURVEY UNIT DESCRIPTION

Survey Unit 9312-0001 (Containment) is designated as Final Status Survey (ESS)Class 1 and consists of approximately one thousand nine hundred-seventy five(1,975) square meters of open land and is located approximately one thousand fourhundred eighty feet (1,480 ft) to the southeast of the site benchmark (Northing:237370.20, Easting: 667394.57) site reference coordinate system benchmark used atHaddam Neck Plant (HNP) (see Attachment 1). The survey unit is bounded asfollows: land Survey Unit 93 12-0005 and land Survey Unit 93 12-0006 to the north(called north as oriented with the north to south flow of the Connecticut River), landSurvey Unit 9312-0003 to the west and south and land Survey Unit 9312-0002 to theeast and south. As a result of demolition and remediation activities, the areatopography is mostly flat and de-vegetated. The survey unit has a moderate sloperunning from east to west.

The reference coordinates associated with this survey unit are E009 through E0 12 byS067 through S069 (refer to "HNP License Termination Plan" (LTP) Section 5.4.4).The reference coordinates provide the maximum dimensions of a rectangle containingthis survey unit. Some areas contained in this rectangle may not be part of this surveyunit. 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, "SurveyUnit Classification. "

RELEASE RECORD

During plant operation, Survey Unit 9312-0001 was the location of significant,radiologically contaminated structures and systems, namely the reactor, the reactorsystems and the Containment structure.

The Containment Building housed the reactor, reactor primary systems andcomponents as well as numerous other support systems. With the exception ofvarious service water, gas and air systems, the majority of the systems within theContainment were radiologically contaminated. Radioactive material concentrationsin many of these components and systems were high enough to create high radiationareas in their vicinity. The entire Containment Building interior was posted as a"Contaminated Area". Hi storical surveys of the building show that significant levelsof fixed and loose contamination were present in this structure. Some components,equipment, structural steel and concrete became radioactive due to neutron activation.

A review of the Historical Site Assessment and Supplement, as well as, otherhistorical documents (e.g., the I OCFR5O.75(g)(l) files) indicated a significant numberof operational events have impacted Survey Unit 9312-0001. These events includedsignificant spills and leakage from contaminated systems. These events would havehad the most impact on the radiological condition of subsurface structures and footers;and the underlying soil and bedrock prior to system and structural decontaminationand demolition.

Major demolition and remediation activities began in 2002. All contaminatedsystems and components located inside the Containment Building, including thereactor vessel, were removed and appropriately packaged and shipped to an approvedoff-site disposal facility. Interior structural surfaces inside the Containment Buildingwere decontaminated to ensure contamination levels were acceptable for controlleddemolition, Interior walls and floors were then demolished and removed. TheContainment liner was removed with the exception of the Incore Sump, which wasfilled with grout to the basement floor elevation. The remaining interior surfacesinside the Containment shell were decontaminated.

Following decontamination, the Containment basement was filled with soil to thegrade of the exterior open land. The above grade portion of the Containmentstructure was then demolished and removed. Fill was then placed over the surveyunit, raising the grade of the area by approximately four (4) feet. No above gradestructures currently remain within Survey Unit 93 12-000 1.

Outside of the structures, considerable remediation was performed on the soilssurrounding the Containment structure, particularly around the northeast, northwestand southeast quadrants of the survey unit. A large excavation was created to thenorth of the Containment that was designated as Excavation #1. This excavationincluded the area in the vicinity of the Refueling Waster Storage Tank and thePrimary Auxiliary Building (PAB) corridor. A second large excavation, designatedas Excavation #2 was located over the Primary Auxiliary Building (PAB) footprint.A third excavation, designated as Excavation #3 was located in the area between theContainment Building and Spent Fuel Building (SFB).

As adjacent structures were demolished, soil was excavated and removed. Thisprocess continued until bedrock was exposed. Subsurface structures and footings thatremained following demolition and excavation include the Containment Mat, theCable Vault wall, the Service Building east wall, a remnant of the PAB northwestwall, Waste Disposal Building (WDB) footing and miscellaneous fragments offootings and slabs on the bedrock. As with the Containment basement shell, allexcavations were backfilled following the performance of radiological assessments.

In Survey Area 9312, post-remediation soil samples were taken from the as-leftsurface soils under two (2) Survey and Sampling Work Plans, SSWVP-06-08-000 andSSWPT-06-12-001. Thirty-five (35) post remediation surface soil samples werecollected from the various locations within Survey Area 9312. All samples werecollected and analyzed by gamma spectroscopy by an approved off-site laboratory.Ten (10) of the thirty-five (35) post remediation samples collected were analyzed forthe full suite of "Hard-to-Detect" (HTD) radionuclides specified in the LTP,Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and asprovided in Table 3. Statistical quantities (mean, median and standard deviation)from the 2006 post-remediation survey conducted under SSWP-06-08-000 andSSWP-06-12-001 are provided in Table 1.

A review of this sample data shows Cs-137 and Co-60 to be the primaryradionuclides of concern, with both isotopes reported at fairly low concentrations.The sample population as a whole was evaluated to assess the distribution of thedetected radionuclides. The radionuclide distribution percentage for each sample inthe population was calculated by dividing the concentration of each detectedradionuclide by the total activity concentration in the sample, expressing theabundance of the specific nuclide in the sample compared against the total activity.The mean radionuclide distribution was then calculated by taking the average of theindividual sample distribution fractions. The results are provided in Table 2.

RELEASE RECORD

Cs-137 0.689

Co-60 0.3 11

No HTD radionuclides were positively identified in concentrations meeting theaccepted criteria for detection (i.e., a result greater than two (2) standard deviationsuncertainty). Radionuclide screening or de-selection is a process where an individualradionuclide or aggregates may be considered insignificant and eliminated from theFSS. The criteria for de-selection are concentrations less than 5% for individualradionuclides and less than 10% for aggregates.

While Sr-90 was not identified in the soil characterization results, it was decided toinclude Sr-90 is a radionuclide of concern for this survey unit as Sr-90 was prevalentin the soils prior to remediation. Therefore, all volumetric soil samples taken as partof the survey design for this survey unit were subjected to direct analysis for Sr-90.

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

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

Based upon the identification of radioactive material above the DerivedConcentration Guideline Levels (DCGLs), and the need for radiological remediation,it was concluded that there was some probability for residual radioactivity inconcentrations greater than the DCGLs, justifying a final survey unit classification ofClass 1 (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process asdescribed by the LTP, Procedure RPM 5. 1-11, "Preparation of Final Status SurveyPlan," and the "Multi-Agency Radiation Survey and Site Investigation Manual"(MARSSIM). A summary of the main features of the DQO process are providedherein.

The DQO process incorporated hypothesis testing and probabilistic samplingdistributions to control decision errors during data analysis. Hypothesis testing is aprocess based on the scientific method that compares a baseline condition to analternate condition. The baseline condition is technically known as the nullhypothesis.

Revision 06 6



RELEASE RECORD

Hypothesis testing rests on the premise that the null hypothesis is true and thatsufficient evidence must be provided for rejection. In designing the survey plan, theunderlying assumption, or null hypothesis was that residual activity in the survey unitexceeded the release criteria. Rejection of the null hypothesis would indicate thatresidual activity within the survey unit does not exceed the release criteria.

The primary objective of the FSS plan was to demonstrate that the level of residualradioactivity in Survey Unit 9312-0001 did not exceed the release criteria specified inthe LTP and that the potential dose from residual radioactivity is As Low AsReasonably Achievable (ALARA).

A fundamental precursor to survey design is to establish a relationship between therelease criteria and some measurable quantity. This is done through the developmentof DCGLs. The DCGLs represent average levels of radioactivity above backgroundlevels 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 forsoil (called Base Case Soil DCGL), existing groundwater radioactivity and futuregroundwater radioactivity that will be contributed by building basements andfootings.

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

Equation 1

Hiotai -H Soil ±H ExistingGW ±H FutureG W

The total dose under the LTP criteria is twenty-five (25) mrem/yr Total EffectiveDose Equivalent (TEDE) from all three (3) components. The allowable total doseunder the Connecticut Department of Environmental Protection (CTDEP)radiological remediation standard for CY is nineteen (19) mrem/yr TEDE. To satisfyboth the LTP and CY CTDEP criteria, the dose from soil must be reduced whenusing the existing and future groundwater dose values discussed above.

This survey area is affected by existing groundwater (reference CY memoISC 06-024). Therefore, the dose contribution from existing groundwater is boundedby two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactivecontamination, as there are underground foundations containing residual radioactivematerial within the groundwater saturated zone in the area (reference CY memoISC 06-024). The dose contribution from future groundwater, the third dosecomponent, is bounded by two (2) mremlyr TEDE.

The concentration of residual radioactivity resulting infifteen (15) mremlyr TEDE is designated as the Operational DCGL (DCGLop), andhas been established for the radionuclides of concern as provided in Table 3.

RELEASE RECORD

Another important facet of the DQO process is to identify the radionuclides ofconcern and determine the concentration variability. Soil samples were collected in2006 to establish the radiological condition of Survey Unit 9312-0001 for FSS.Cs-137 and Co-60 were the two (2) gamma emitting radionuclides reported inconcentrations with the potential for exceeding the release criteria. Sr-90 wasincluded as a radionuclide of concern due to its prevalence in the soil prior toremediation. The characterization data were used for the survey design and areprovided in Table 1.

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

As, part of the DQOs applied to laboratory processes, analysis results were reported asactual calculated results. Results reported as less than Minimum DetectableConcentration (MDC) were not accepted for FSS. Sample report summaries includedunique sample identification, analytical method, radionuclide, result, and uncertaintyto two (2) standard deviations, laboratory data qualifiers, units, and the required andobserved MDC.

4. SURVEY DESIGN

The level of effort associated with planning a survey is based on the complexity ofthe survey and nature of the hazards. Guidance for preparing FSS plans is providedin Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans". The FSS planuses an integrated sample design that combines scanning surveys and sampling whichcan be either random or biased.

The DQO process determnined that Cs-137, Co-60 and Sr-90 would be theradionuclides of concern in Survey Unit 93 12-0001 (refer to Section 3). Thecharacterization survey did not include any other additional HTD radionuclides ofconcern for this survey unit. As Sr-90 concentrations were determined by directanalysis, surrogate DCGLs were not required as part of the survey design for thissurvey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Otherradionuclides that were positively identified in concentrations greater than thescreening criteria during the performnance of this FSS would be evaluated to ensureadequate survey design.

As the survey unit is classified as a Class 1 surface soils area, and discrete, elevatedareas of contamination was possible, the application of the Elevated MeasurementComparison (EMC) remained an option.

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

RELEASE RECORD

The number of soil samples for FSS was determined in accordance with ProcedureRPM 5.1-12, "Determination of the Number of Surface Samples for Final StatusSurvey." The Lower Bound of the Gray Region (LBGR) was set in accordance withProcedure RPM 5. 1-11 ito 0.73 to achieve a relative shift (A/cy) in the range of 1 and 3.The resulting adjusted relative shift was 2.0. A Prospective Power Curve wasgenerated using COMPASS, a software package developed under the sponsorship ofthe United States Nuclear Regulatory Commission (USNRC) for implementation ofthe MARS SIM in support of the decommissioning license termination rule(I OCFR2O, Subpart E). The result of the COMPASS computer run showed adequatepower for the survey design. The survey design specified. fifteen (15) surface soilsamples for non-parametric statistical testing. Based upon a review of the historicalinformation and Characterization Survey data, four (4) judgmental samples weretaken in this survey area. One (1) judgmental sample was taken at the northeastcorner of the survey unit in the vicinity of the "Tank Farm" excavation; two (2)judgmental samples were taken in the southeast corner of the survey unit in thevicinity of the Fuel Transfer Tube excavation and the Spent Fuel Building foundationand one (1) judgmental sample was taken in the northwest quadrant in the vicinity ofthe Primary Auxiliary Building excavation.

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

Sample locations were identified using AutoCAD-LT, a commercially availableplotting software package with coordinates consistent with the Connecticut StatePlane System. These coordinates were integrated with a GPS to locate samplelocations in the field. Sample Measurement Locations for the design are listed withthe GPS coordinates in Table 4.

Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selectedfor HTD analysis. Two (2) soil samples, or 13% of the number of samples that wouldbe used for non-parametric statistical testing were randomly selected for HTDradionuclide analysis using the Microsoft Excel "RANDBETWEEN" function. Eachsample was sent off-site for a full suite analysis of the HTD radionuclides specified inthe LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" andas provided in Table 3.

The LTP requires a minimum of 5% of the samples taken for non-parametricstatistical testing be selected for QC evaluation. The implementation of qualitycontrol measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessmentfor Final Status Survey," included the collection of one (1) soil sample for "splitsample" analysis by the off-site laboratory. This location was selected randomlyusing the Microsoft Excel "RANDBETWEEN" fuinction.

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 soilsample measurement results are those levels specified in LTP, Table 5-8. Table 5provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION

Final status survey field activities were conducted under a Final Status Survey Plan(FSSP). The FSSP package included a detailed survey plan, job safety analysis, jobplanning checklist and related procedures for reference. Daily briefings wereconducted to discuss the expectations for job performance and the safety aspects ofthe survey. The "Daily Survey Journal" was used to document field activities andother inform-ation pertaining to the FSS.

A single scan area was established that constituted approximately 100% of the surfacearea of Survey Unit 9312-0001. Grid lines, one (1) meter wide, were painted on theground of the scan area. A background survey was performed around the survey unitand it was determined that, using an Eberline E-600 with a SPA-3 sodium iodidedetector, background ranged from 7,170 counts per minute (cpm) up to 13,200 cpm.

RELEASE RECORD

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

Meastfr ement locations were identified* in North American Datum (NAD) 1927coordinates using GPS coordinates; sample locations were identified and marked witha surveyor's flag or paint for identification. At each sample location, a one (1) meterradius circle was established around the sample flag or paint mark was scanned forelevated radiation levels.

Nineteen (19) surface soil samples were collected and packaged in accordance withHaddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media forFinal Status Survey" and FSS design. Samples were controlled, transported, stored,and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol inaccordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status SurveySamples."

Two (2) samples (93 12-0001-005F and 9312-0001-015F) were randomly selected forHTD radionuclide analysis.

The implementation of survey specific quality control measures included thecollection of one (1) sample (9312-0001-003F) for "split sample" analysis.

6. SURVEY RESULTS

All field survey activities were conducted between March 24, 2007 and March 26,2007.

The sample locations identified in the FSS plan were scanned over approximately aone (1) meter radius for elevated radiation levels. Table 6 provides an overview ofthe scan results for sample measurement locations. Scan results are provided inAttachment 2.

The off-site laboratory employed for the radiological analyses of samples wasGeneral Engineering Laboratories, LLC. The laboratory analyzed the fifteen (15)samples collected for non-parametric statistical testing, the associated field splits andthe four (4) judgmental samples using gamma spectroscopy. Gamma spectroscopyanalysis was performed to the required MDCs. Gamma spectroscopy resultsidentified some radionuclides meeting the accepted criteria for detection (i.e., a resultgreater than two (2) standard deviations uncertainty). However, Cs-137 was the onlygamma-emitting radionuclide reported in any appreciable concentration.

Cs-137 was positively identified in six (6) of the fifteen (15) samples collected fornon-parametric statistical testing. Co-60 was positively identified in one (1) samplefrom the statistical sample population. The mean of the gamma spectroscopicanalysis results for the sample population indicated that Cs-137 was present at levelsat or below expected environmental levels for Cs-137 within the vicinity of the HNPas presented in the Health Physics TSD BCY-HP-0063.

The "sum-of-fractions" or "unity rule" is the mathematical test used to evaluatecompliance with radiological criteria for license termnination when more than oneradionuclide has been determined to be potentially present. The combination of thefractions of each detected radionuclide against their respective Operational DCGLmust be less than or equal to one (1).

RELEASE RECORD

In addition to the non-parametric statistical sample population, four (4) judgmentalsurface soil samples were taken at biased locations. These locations were selected bythe FSS Engineer based upon a review of the historical site assessment for this areaand previous survey results. These judgmental soil samples were analyzed forCs- 137, Co-60 and Sr-90 in accordance with the DQOs used during the survey design.A summary of the four (4) judgmental samples collected as well as the results of theunity rule calculation for the identified radionuclides are provided in Table 9.

In addition to Cs-137 and Co-60, Sr-90 was also identified during the DQO processas a radionuclide of concern. Subsequently, all samples were subjected to analysis bygas proportional counting for Sr-90. All analyses met the required minimum MDC.

Sr-90 was not positively identified (i.e., a result greater than two (2) standarddeviations uncertainty) in any of the fifteen (15) samples collected for non-parametricstatistical testing nor in any of the judgmental soil samples. In addition to Sr-90, theoff-site laboratory also processed, as required by the sample plan, two (2) samples forthe full suite of HTD radionuclides as specified in LTP, Table 2-12, "RadionuclidesPotentially Present at Haddam Neck Plant" and as provided in Table 3. Therequested analyses included alpha spectroscopy, gas proportional counting, and liquidscintillation depending on the radionuclide and the measurement method. Allanalyses performed met the required minimum MDC. No other HTD radionuclideswere positively identified.

7. QUALITY CONTROL

The off-site laboratory processed the split samples and performed gammaspectroscopy analysis. One sample location was selected for analysis, which exceedsthe 5% minimum required by the LTP. The data were evaluated using USNRCacceptance criteria specified in Inspection Procedure 84750 as detailed in HNPProcedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey ".

Revision 0 18



RELEASE RECORD

Cs-137 was not detected in sufficient quantity in the field split results at location93 12-0001-003FS to evaluate in accordance with procedure. Evaluation using thereported results for naturally occurring K-40 resulted in acceptable agreementbetween the field-split results at this location.

Cs-137, Co-60 and Sr-90 were not positively identified in any of the seven (7)samples collected for investigation. Gamma spectroscopy results identified someradionuclides meeting the accepted criteria for detection (i.e., a result greater than two(2) standard deviations uncertainty). However, no gamma emitting radionuclide wasreported in any concentration greater than its respective MDC.

9. REMEDIATION AND RESULTS

Radiological remedial action as described by MARSSIM Section 5.4 was performedin this survey unit prior to FSS. All excavations were characterized and backfilledprior to performing FSS. In the area where remediation occurred, the ground area iscomprised of barren dirt with no vegetation, and the soils have been graded relativelyflat to the corresponding elevation of the adjacent survey units. The results forCs-137 following remediation were well below the Operational DCGL provided inTable 3. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of SoilRemediation in Support of Final Status Survey, " determined that remediation beyondthat required to meet the release criteria is unnecessary and that the remainingresidual 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 RPM5.1-23, "Data Quality Assessment, " for completeness and consistency. The samplingdesign had adequate power as indicated by the Retrospective Power Curve. The SignTest was performed on the data and compared to the original assumptions of theDQOs. The evaluation of the Sign Test results demonstrates that the survey unitpasses the unrestricted release criteria, thus, the null hypothesis is rejected.

Revision 0 220



RELEASE RECORD

Documentation was complete and legible. Surveys and sample collection wereconsistent with the DQOs and were sufficient to ensure that the survey unit wasproperly 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 theOperational DCGL. Also, the retrospective power curve shows that a sufficientnumber of samples were cOllected to achieve the desired power. Therefore, thesurvey unit meets the unrestricted release criteria with adequate power as required bythe DQOs. The basic statistical quantities for the statistical sample population areprovided below in Table 9.

DCGLoP: 4.75E±00 2.29E±00 9.30E-01

Minimum Value: -2.03E-02 -4.50E-03 -3.49E-02

Maximum Value: 7.99E-02 2.57E-02 2.82E-02

Mean: 2.15E-02 5.43E-03 -3.5 1E-03

Median: 1.20E-02 2.14E-03 -7.40E-04

Standard Deviation: 3.28E-02 9.40E-03 1.44E-02

Cs-137 was positively detected in six (6) of the samples collected for non-parametricstatistical testing. The range of the data is less than one (1) standard deviation andthe data set exhibits a calculated positive skew of 0.74. The Cs-137 results arerepresented graphically through posting plots, a frequency plot, and a quantile plot.

Co-60 and Sr-90, although included in the FSS plan for compliance purposes, waspositively identified in only one (1) of the fifteen (15) samples collected for non-parametric statistical testing. Assessment of the basic statistical quantities andgraphical representation of Co-60 and Sr-90 was not considered useful given the non-existent number of actual data points to represent the distribution.

All data, assessments, and graphical representations are provided in Attachment 4.

12. ANOMALIES

No anomalies were noted.

13. CONCLUSION

Survey Unit 9312-0001 has met the final DQOs of the FSS plan. The ALARAcriteria for soils as specified in Chapter 4 of the LTP were achieved. ElevatedMeasurement Comparison was not required.

Revision 0 21



RELEASE RECORD

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

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

The dose contribution from soil is 0.10 mremlyr TEDE based on the averageconcentration 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 considered impacted by future groundwater radioactivecontamination, as there are underground foundations containing residual radioactivematerial within the groundwater saturated zone in the area (reference CY memo ISC06-024). The dose contribution from future groundwater, the third dose component,is bounded by two (2) mremlyr TEDE.

The average total dose from residual radioactivity in this survey unit, includingexposures from the three (3) components as described in Section 3, that is, residualradioactivity in soil, existing groundwater radioactivity, and future groundwaterradioactivity from the burial of concrete foundations or footings from site buildingscontaining residual radioactivity will not exceed 4.10 mremlyr TEDE. Therefore,Survey Unit 9312-0001 is acceptable for unrestricted release.

Data Review Qualifier Definitions

Qualifier Explanation

* 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

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

A The TIC is a suspected aldol-condensation product

* Target analyte was detected in the associated blank

B Metals-Either presence of analyte detected in the associated blank, or

MDL/IDL < sample value < PQL

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

d 5-day SOD-The 2:1 depletion requirement was not met for this sample

E Organics-Concentration of the target analyte exceeds the instrument calibration range

E Metals-%difference of sample and SD is >10%. Sample concentration must meet flagging criteria

H Analytical holding time was exceeded

h Preparation or preservation holding time was exceeded

J Value is estimated

N Metals-The Matrix spike sample recovery is not within specified control limits

N Organics-Presumptive evidence based on mass spectral library search to make a tentative

identification of the analyte (TIC) . Quantitation is based on nearest internal standard

response factor

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 reporting limit

UT Gamma Spectroscopy-Uncertain identification

X Consult Case Narrative, Date Summary package, or Project Manager concerning this qualifier

Y QC Samples were not spiked with this compound

Z Paint Filter Test-Particulates passed through the filter, however no free liquids were observed.

Parmname NOM Sample Qual ~QC Units RPD% REC% Range Anlst Date TimeN/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 thesample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value isless 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 therequirements of the NELAC standard unless qualified on the QC Summary.
