The Discharge Canal is a man-made mile long waterway that runs parallel to, and ultimately communicates with the Connecticut River. The Discharge Canal is subdivided into fifteen (15) survey units including two (2) permanent wetland areas for FSS purposes.

The survey unit is bounded as follows: Discharge Canal Survey Unit 9106-0004 is to the north (called north as orientated with the north to south flow of the Connecticut River), Survey Area 9528 is to the east, Discharge Canal Survey Unit 9106-0006 is to the south and Survey Area 9530 is to the west. The survey unit comprises the canal sediments to the depth of three (3) feet from the top of the sediment layer or the original construction depth and it extends up the canal banks to the mean high water level.This survey unit is bounded by reference coordinates EO 17 through E023 and by S100 through S115 (refer to License Termination Plan Section 5.4.4). The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification. " The historical information, scoping analyses and characterization results provided sufficient data to designate Survey Unit 9106-0005 as Class 2 in May 2006.The "Classification Basis Summary" conducted for this survey unit consisted of: a) A review of the 1OCFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment (HSA) Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walkdown." e) Formal or informal interviews with cognizant personnel.

A review of the 1OCFR50.75(g)(1) database report identified a number of events that may have impacted this survey unit. Several events indicated the potential for plant related contamination in the survey unit. These included a number of primary side system to secondary side system leakage events, Revision 0 3 Revision 0 3 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD contamination found to be present in secondary side systems and components, and unmonitored spills that drained to the discharge canal. In 1986, samples were taken from the legacy dredge spoils removed in 1979 dredged spoils area and from recently dredged canal sediment.

The sample analyses indicated that the concentrations of Cs-137, Co-60 and other radionuclides were a small fraction of the DCGLs for those nuclides that could be identified by gamma spectroscopy. (refer to NE-86-RA-1142 dated 11-13-86).

None the available historical information reviewed would support a conclusion that any residual activity in this survey unit is likely to be present at concentrations greater than the respective DCGLs.Additional information was provided by several historical documents, including the "Results of Scoping Survey", (completed 9/1/98), the "Historical Site Assessment", and the HSA Supplement (dated 6-30-00).

These documents presented the results of several sediment samples taken in 1997. These sample results indicated concentrations of 0.5 pCi/g for Co-60, 0.024 pCi/g for Cs-134 and 0.722 pCi/g for Cs-137.An initial characterization survey of the Discharge Canal was performed during April and May of 2004. However, none of these samples were taken from within the footprint of survey Unit 9106-0005.

A final characterization was performed by Site Closure personnel in April of 2006 to obtain the necessary data of sufficient data quality for Final Status Survey (FSS) planning purposes.

Six (6) 3-foot core sediment samples were taken from six (6) locations.

All of the samples were analyzed by gamma spectroscopy.

Since Hard-to-Detect (HTD) analyses were not performed and since Sr-90 was found to be a nuclide of concern in an adjacent discharge canal Survey Unit (SU 9106-0006), for conservatism it was included as a nuclide of concern in Survey Unit 9106-0005.

The Sr-90 concentration statistics were also.included in the variance calculations to determine the size of the sample population for FSS. Although no additional HTD testing was performed for characterization; four (4) of the fifteen (15) samples taken to demonstrate compliance with the release criteria during FSS were tested for the full suite of HTD nuclides to provide additional assurance that all of the radionuclides of concern were appropriately addressed.

As a result of characterization, the radionuclides of concern identified for FSS planning purposes were Cs-137, Co-60 and Sr-90 (refer to Table 1).Revision 0 4 Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD Minimum Value: 6.64E-02 1.16E-01 1. 14E-OY Maximum Value: 2.79E-01 5.59E-01 7.16E-02 Mean: 1.73E-01 3.08E-01 4.17E-02 Median: 1.63E-01 2.64E-0I 3.94E-02 Standard Deviation:

Based upon the historical information and the results of radiological surveys performed during characterization, it was concluded that there was a low probability for residual radioactivity to be present in this survey unit in concentrations greater than the Operational DCGLs justifying a final survey unit classification of Class 2 (refer to Section 3).3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning is based on 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 incorporates 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 satisfy the release criteria objective of the FSS.The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9106-0005 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).Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD 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 Derived Concentration Guideline Levels (DCGLs). The DCGLs represent the concentration of radioactivity above background, equivalent to a dose-based release criterion and is 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), for existing groundwater radioactivity and for future groundwater radioactivity that will be contributed by building foundations and footings.As described in detail in the LTP, the dose model applied to the discharge canal presumes that the canal sediments are dredged to a depth of three (3) feet below the top of the sediment layer and spread for the planting of crops per the Resident Farmer Scenario.

Consequently, the soil DCGLs are directly applied to the canal sediment media.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 I shows the mathematical relationship between the three (3) components and the total dose.Equation I.HTotal=Hsoil (sediment)

+ HExisting GW +/- HFuture GW 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 Connecticut Yankee (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 groundwater dose values discussed above.This survey unit is not affected by existing groundwater or by future groundwater (reference CY memo ISC 06-024). Therefore, dose contribution from existing and future groundwater is zero (0) mrem/yr TEDE, based on field data.Equation 2: 19 mrem/yrTotaI=

19 mrem/yrsoi 0+0 mrem/yrExisting GW+0 mrem/yrFuture GW The allowable dose for soil in this survey unit is nineteen (19) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in nineteen (19) mrem/yr TEDE is designated as the Operational Revision 0 6 Revision 0 6 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD DCGL, and has been established for the radionuclides of concern as provided in Table 2.Note: The survey design used a much smaller value for investigation than the Operational DCGL provided by Table 2 to conservatively account for the contribution to the total dose from existing and future groundwater which had not been established at the time of planning the FSS.C-14 5.66E+00 4.30E+00 2.26E-01 Mn-54 1.74E+01 1.32E+O1 6.96E-0 I Fe-55 2.74E+04 2.08E+04 1.1OE+03 Co-60 3.81E+00 2.90E+00 1.52E-01 Ni-63 7.23E+02 5.49E+02 2.89E+0 I Sr-90 1.55E+00 1.18E+00 6.20E-02 Nb-94 7.12E+00 5.41 E+00 2.85E-01 Tc-99 1.26E+01 9.58E+00 5.04E-01 Ag- 108m 7.14E+00 5.43E+00 2.86E-01 Cs-134 4.67E+00 3.55E+00 1.87E-01 Cs-137 7.91 E+00 6.01E+00 3.16E-01 Eu-152 1.01E+01 7.68E+00 4.04E-01 Eu-154 9.29E+00 7.06E+00 3.72E-01 Eu-155 3.92E+02 2.98E+02 1.57E+01 Pu-238 2.96E+O1 2.25E+01 1.18E+00 Pu-239/240 2.67E+O 1 2.03E+01 1.07E+00 Pu-241 8.70E+02 6.61E+02 3.48E+01 Am-241 (5) 2.58E+01 1.96E+O1 1.03E+00 Cm-243/244 2.90E+0 I 2.20E+O 1 1.1 6E+00 (1) Bold indicates those radionuclides that are considered to be Hard to Detect (HTD)(2) The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to twenty-five (25) mrem/yr TEDE (3) The Operational DCGL is equivalent to nineteen (19) mrem/yr TEDE (4) The required MDC is equivalent to one (1) mrem/yr TEDE (5) Americium-241 can be analyzed by gamma and alpha spectroscopy and is considered to be Easy to Detect (ETD). The preferred result is the alpha spectroscopy's when both analyses are performed.

Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

The radiological data that was used to support the DQO process, was provided by the characterization surveys performed in 2004 and 2006, as discussed in Section 2. Cs-137, Co-60 and Sr-90 were found to be the predominate radionuclides of concern., The basic statistical quantities (i.e., mean, standard deviation, median) for Cs-137, Co-60 and Sr-90 are provided in Table 1.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 ".This survey was initially designed to ten (10) mrem/yr TEDE. At the time when the survey was designed, the dose contribution for existing and future groundwater had not yet been determined.

Consequently, a conservative value was chosen for the Operational DCGL. This approach is no longer required as the total dose from existing and future groundwater has been established.

The dose for soil used for this survey unit to demonstrate compliance with the LTP criteria is nineteen (19) mrem/yr TEDE, as discussed in Section 2 of this Release Record.The DQO process determined that Cs-137, Co-60 and Sr-90 were the radionuclides of concern (refer to Section 3). The sum of fractions or unity rule was used with the individual Operational DCGLs because multiple radionuclides (Cs-137, Co-60 and Sr-90) were considered in the survey design.Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of nearby adjacent areas and via screening process described in LTP Section 5.4.7.3, "Gross Activity DCGLs". Sr-90 concentrations in sediment and soil were ascertained by direct analysis.Radionuclide screening or de-selection is a process, described in LTP Section 5.4.7.2, where an individual radionuclide or aggregate 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 the aggregate of all radionuclides de-selected.

This process was applied to analysis data for this survey unit.Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 2 area and discrete, elevated areas of contamination were not expected.The Sign Test was selected as the non-parametric statistical test to demonstrate that the null hypothesis was rejected.

The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

In addition, this approach is conservative since it includes background Cs-137 as part of the sample set.The number of sediment samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set to 0.78 in accordance with Procedure RPM 5.1-11 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting 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 MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. This indicates that the survey unit has a high probability of rejecting the null hypothesis, assuming that the characterization data are representative of the FSS results. Survey design specified fifteen (15) sediment core samples for non-parametric statistical testing.The grid pattern and locations of the sediment samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14,"Identifying, and Marking Surface Sample Locations for Final Status Survey. " Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 2 area.Judgmental sampling was included as a feature of this survey design to account for any anomalies potentially identified in the field.Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Revision 0 9 Revision 0 9 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD Table 31 -,ample Measurement Loc'ationis N~ith Associated

Sample locations 9106-0005-006F and 9106-0005-012F were found to be on dry land. Consequently, they were randomly re-located using the VSP software to two (2) new locations designated as 9106-0005-017F and 9106-0005-018F.

Since sample 9106-0005-012F was randomly selected as a Quality Control (QC) split sample, sample 9106-0005-018F was designated as the replacement QC sample. Any location(s) identified by biased methods, were not included in Table 3.One (1) biased sample was required by the sample plan. This sample was designated as sample location 9106-0005-016F.

Sample results for sample location 9106-0005-016F are presented in Section 6, "Survey Results" and are also provided in Table 6.Four (4) sediment samples were analyzed for the full suite of radionuclides specified in Table 1, exceeding the requirement to analyze 5% of the sample population for HTD analysis specified in procedure RPM 5.1-11. Two (2) of the four (4) samples were randomly selected using the Microsoft Excel"RAND" function.

The two (2) samples exhibiting the highest observed radionuclide concentrations by gamma analyses were also selected.The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " required the collection of two (2) soil samples for "split sample" analysis by the off-site laboratory.

These locations were selected randomly using the Microsoft Excel Revision 0 10 Revision 0 10 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD"RAND" function.

The number of quality control samples exceeded the 5%requirement as specified by the LTP.Section 5.7.3.2.6 of the LTP specifies that scanning is not required for the FSS of the Discharge Canal.

SURVEY IMPLEMENTATION Final Status Survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0021.

The WP&IR package included a detailed FSSP, 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.Measurement locations were identified in North American Datum (NAD) 1927 coordinates that were supplied to the sampling vendor, Ocean Surveys, Inc.(OSI) of Old Saybrook, Connecticut.

Discharge Canal sampling was accomplished using direct push technology to collect composite samples of Revision 0 I1I Revision 0 11 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD bottom and mean high water mark sediments.

Sediment cores from the Discharge Canal were obtained by OSI using a vibrating corer that is platform mounted on a sampling vessel. The core barrel was a three (3) inch diameter thin-walled aluminum tube which also served as a core liner (ten (10) feet or less). A core catcher was available to prevent the sample from sliding out of the bottom of the tube. Vessel positioning and the determination of sample locations were accomplished using a GPS interfaced with a navigation and data logging system.After extraction, water was drained from above the sample by drilling holes above the sediment.

The liner was cut, capped, sealed, labeled and turned over to site personnel who processed and controlled the samples under Chain of Custody (COC) protocols in accordance with procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples. " Rinsing of the barrel and associated equipment was performed between sampling events. New aluminum tubes were used for each sample to prevent cross-contamination of subsequent samples.The fifteen (15) sediment 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 COC protocols.

Four (4) samples (9106-0005-005F, 9106-0005-009F, 9106-0005-OIOF and 9106-0005-014F) were selected for HTD radionuclide analysis by the off-site laboratory.

The implementation of quality control measures included the collection of two (2) split samples at locations 9106-0005-003F and 9106-0005-018F for comparative analysis by the off-site laboratory.

6. SURVEY RESULTS The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories (GEL) -Charleston, South Carolina.

The laboratory analyzed the fifteen (15) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy.

Sr-90 was analyzed by gas flow proportional counting.

All analyses were performed to the required MDC.Cesium-137 was identified in twelve (12), Co-60 was identified in eight (8) and Sr-90 in four (4) of the fifteen (15) samples.Several other radionuclides which were positively identified (i.e., a result greater than two (2) standard deviations uncertainty) could be de-selected or excluded using the 5% and 10% rule described in Section 5.4.7.2 of the LTP.Revision 0 12 Revision 0 12 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD The off-site laboratory also processed four (4) samples for full HTD analysis as required by the sample plan. The requested analyses included alpha spectroscopy and liquid scintillation depending upon the radionuclide and the measurement method. All analyses were performed to the required MDC. Four (4) of the HTD radionuclides met the acceptance criteria for detection (i.e., a result greater than two standard deviations uncertainty) in more than one (1)sample; however, each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10% rules.None of the sample results exceeded the Operational DCGL or required further investigation.

Sample locations 9106-0005-006F and 9106-0005-012F were found to be on dry land. Consequently, they were randomly re-located using the VSP software to two (2) new locations designated as 9106-0005-017F and 9106-0005-018F.

Since sample 9106-0005-012F was randomly selected as a Quality Control (QC) split sample, sample 9106-0005-018F was designated as the replacement QC sample.One (1) biased sample was required by the sample plan. This sample was designated as sample location 9106-0005-016F.

Sample results for sample location 9106-0005-016F are presented in Table 6 below.Revision 0 13 Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD Tabihe 6 -Biasei SampleResults C-17 Co-60 Sr-9O0 Fraction of the Sample Number p>i,- 1&p1/g_ pCi/g, Operational 9106-0005-016F

QUALITY CONTROL The two (2) split samples taken for QC were analyzed by the off-site laboratory.

The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 and as detailed in HNP Procedure RPM 5.1-24,"Split Sample Assessment for Final Status Survey. " One (1) split-sample (9106-0005-018F/S) did not meet the comparison criterion for Co-60. A possible cause for this anomaly could be the presence of Co-60 in the form of discrete particles.

Such a physical form does not lend itself to homogenous mixing in a sediment matrix and, therefore, is not necessarily an indicator of inadequate sampling or sample preparation methodology.

In this sample, K-40, a natural radioisotope, was found to be present at an acceptable level of agreement, therefore, the comparison was determined to be acceptable.

For the other QC split samples, there was an acceptable level of agreement between the samples for all other detectable radionuclides.

The sample analysis vendor, GEL, maintained quality control and quality assurance plans as part of normal operation.

Refer to Attachment 2 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS One (1) sample result was found to exceed the design DCGL, but was below the nineteen (19) mrem/yr operational DCGL, as specified in Table 4. Confirmatory samples were collected to determine the extent of contamination.

The extent was bounded by taking four (4) confirmatory samples, one (1) in each major compass direction (i.e., North, East, South, West), two (2) meters distant from the elevated sample location.

The gamma spectroscopy results are included in Table 7.Revision 0 14 Revision 0 14 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD 01OF O0OA 4.63E-02 7.70E-02 0.00442 3.80E-02 010B 9.08E-02 1.15E-01 -0.00561 5.01E-02 010C 1.92E-01 5.22E-01 0.00471 2.16E-01 010D 6.30E-01 2.24E+00 0.0219 8.97E-0I (1) The investigation of sample 01OF was initiated upon a sample result greater than the original design dose often (10) mrem/yr, prior to finalization of the dose contribution due to groundwater.

Final results were evaluated against an Operational DCGL which considered the groundwater dose contribution.

(2) The Operational DCGLs are 6.01 pCi/g for Cs-137, 2.90 pCi/g for Co-60 and 1.18 for Sr-90; these are used in conjunction with the unity rule to achieve nineteen (19)mrem/yr TEDE.The confirmatory results demonstrated that no measurements exceeded the nineteen (19) mrem/yr Operational DCGL, indicating that no further actions are warranted.

9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria to be unnecessary and that the remaining residual radioactivity in soil was ALARA.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN The survey was designed to ten (10) mrem/yr TEDE which was conservative and necessary at the time of FSS planning.

It is no longer required as the total dose from existing and future groundwater has been established.

The dose for soil used to demonstrate compliance with the LTP and CTDEP criteria is nineteen (19) mrem/yr TEDE as discussed in Section 2 of this Release Record.11. DATA QUALITY ASSESSMENT (DQA)The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment. " The sample 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 indicates that the survey unit passes the unrestricted release criterion, thus, the null hypothesis is rejected.Revision 0 15 Revision 0 15 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 2.The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation).

The standard deviation was slightly more than the value used for the survey design. This is represented by the shift in the retrospective power curve as shown in Attachment 2f. This would indicate a need to change the original LBGR in order to maintain the number of samples at fifteen (15) to meet the Operational DCGL. However, the value of LBGR is not a critical issue as the survey unit has passed the statistical test, and the mean and median values are well below the Operational DCGL when used in conjunction with the unity rule. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power.Therefore, the survey unit meets the unrestricted release criterion with adequate power as required by the DQOs.The range of the data, about 3.23 standard deviations, was not unusually large.The difference between the mean and median was 40.8% 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 shows some positive skewness as confirmed by the calculated skew of 2.01.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES The anomalies associated with the disagreement between the field splits has been discussed in Section 7. The source of the disagreement for Co-60, was likely due to Co-60 being present in the form of discrete particles.

Such a physical form does not lend itself to homogenous mixing in a sediment matrix.No other anomalies were identified in this survey unit.13. CONCLUSION Survey Unit 9106-0005 has demonstrated compliance with the dose based, unrestricted release criterion.

The sample data passed the Sign Test and the null hypothesis was rejected.

The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

Reclassification and remediation of this survey unit was not required.Graphical representation of data indicates some positive skewness that is probably due to localized differences in particulate deposition rates, hydraulic velocity and sedimentation rates. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.

The survey unit was properly designated as a Class 2 survey unit.Revision 0 16 Revision 0 16 DISCHARGE CANAL SURVEY UNIT 9106-0005 RELEASE RECORD The dose contribution from sediment in this survey unit is 2.2 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey unit is not affected by existing groundwater (reference CY memo ISC 06-024). It has been determined that the dose contribution from existing groundwater sources is bounded by zero (0) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no 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.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 2.2 mrem/yr Total Effective Dose Equivalent (TEDE).14.
