17 Attachment 1 -Figures (6 pages including cover)Attachment 2 -Sample and Statistical Data (273 pages including covers)Revision 0 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9106-0006 (Discharge Canal) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 9,716 m 2 (2.40 acres) of water covered sediment in an area located approximately 0.68 miles from the reference coordinate system benchmark used at the Haddam Neck Plant (HNP)(see Attachment 1, Figure 1). 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 9106-0005 is to the north (called north as orientated with the north to south flow of the Connecticut River), land surface area Survey Unit 9521 is to the east, Discharge Canal Survey Unit 9106-0007 is to the south and Discharge Canal area 9106-0012 (formerly a part of 9530) is to the west. The survey unit comprises the canal sediments to the deeper of three (3) feet or the original construction depth and it extends up the canal banks to the mean high water level.The reference coordinates associated with this survey unit are E026 through E032 by S120 through S133 (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 9106-0006 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 lOCFR50.75(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 9106-0006 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 ýof 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.A final characterization was performed by Site Closure personnel in April and May of 2004. Six (6) sediment samples were taken. All of the samples were analyzed by gamma spectroscopy, Sr-90 and tritium. Additionally, Hard-to-Detect (HTD) analyses were performed on one (1) sample. The radionuclides of concern identified in the sample data for FSS planning purposes were Cesium-137, Cobalt-60 and Sr-90. All other positively detected isotopes could be screened out based on the 5%/10% rule of Section 5 of the LTP. The statistics for each of the radionuclides of concern are listed in Table 1.-asic StatisticalQuanties for- (s137 a 0 fd 99fmin the et~r:; Characterization Sm-Nu paalttrCs137 (pCi/~g) I ~Co'-6ý (jpCig)~ I Sr-90.(pCi/g)

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).Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 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 9106-0006 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity.

This is done through the development of 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 1 shows the mathematical relationship between the three (3) components and the total dose.Equation 1: Revision 0 5 Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 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 existing and future groundwater dose values discussed above.This survey unit is not affected by existing or 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/yr 1 otaff 19 mrem/yrsoil+

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 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.Revision 0 6 Revision 0 6 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD Table 2 -Radionjuclide Specific Base Case Soil DCGL, Operational C s and Required Minimum Detectable Concentrations Radionuclide Case Soil Operational pCGL Requi red MDCo H-3 4.12E+02 3.13E+02 1.65E+01 C-14 5.66E+00 4.30E+00 2.26E-0I Mn-54 1.74E+OI 1.32E+01 6.96E-01 Fe-55 2.74E+04 2.08E+04 1.1 OE+03 Co-60 3.81E+00 2.90E+00 1.52E-01 Ni-63 7.23E+02 5.49E+02 2.89E+01 Sr-90 1.55E+00 1.1 8E+00 6.20E-02 Nb-94 7.12E+00 5.41E+00 2.85E-0I Tc-99 1.26E+OI 9.58E+00 5.04E-01 Ag- 108m 7.14E+00 5.43E+00 2.86E-0I Cs-134 4.67E+00 3.55E+00 1.87E-01 Cs-137 7.91E+00 6.01E+00 3.16E-01 Eu- 152 1.01E+01 7.68E+00 4.04E-0I Eu-154 9.29E+00 7.06E+00 3.72E-0I Eu-155 3.92E+02 2.98E+02 1.57E+01 Pu-238 2.96E+OI 2.25E+01 1.18E+00 Pu-239/240 2.67E+O I 2.03EE+01 1.07E+00 Pu-241 8.70E+02 6.61E+02 3.48E+01 Am-241 (5) 2.58E+01 1.96E+01 1.03E+00 Cm-243/244 2.90E+O I 2.20E+01 1.16E+00 (1) Bold indicates those radionuclides considered to be Hard to Detect (HTD)(2) The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to 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.

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 Revision 0 7 Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 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 5.4.7.2, "Gross Activity DCGLs". Sr-90 concentrations in sediment and soil were ascertained by direct analysis.Radionuclide screening or de-selection is a process where an individual radionuclide or aggregate may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations that are less than 5%for individual radionuclides and that are less than 10% for the aggregate of all radionuclides that are de-selected.

This process was applied to analysis data for this survey unit.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 soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Samples for Final Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.5 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting relative shift was 2.7. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.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 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.'TaIbie 3 -apeMeasur~emeiutlocations with Associated GPS Coordinates"-

Grid Sample locations 9106-0006-002F and 9106-0006-013F were found to be on dry land. This was also the case for biased sample location 9106-0006-16F.

Consequently, the grid sample locations were randomly re-located using the VSP software to two (2) new locations designated as 9106-0006-019F and 9106-0006-020F.

Biased sample 9106-0006-016F was relocated to location 9106-0006-018F, a location that also was in the vicinity of the outfall that was of interest.Three (3) 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)samples were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RAND" functions.

In addition, the two (2) samples, which were determined to contribute the greatest dose based on gamma only analyses, were also selected for HTD analyses.

Coincidentally, one of these (sample 9106-0006-010F) was selected in the earlier random selections, so only one additional sample was analyzed based on the gamma results The implementation of survey specific quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " included the collection of two (2) soil samples for "split sample" analysis by the off-site laboratory.

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

The number of quality control samples exceeded the 5% requirement.

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 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 Revision 0 I1I Revision 0 11 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 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.

Three (3) samples (9106-0006-005F, 9106-0006-009F and 9106-0006-010F) 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 9106-0006-007F and 9106-0006-018F for "split sample" 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 ten (10), Co-60 was identified in nine (9) and Sr-90 in one (1) 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.The off-site laboratory also processed three (3) 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. Two (2) of the HTD radionuclides met the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty) in more than one (1)Revision 0 12 Revision 0 12 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 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.

These samples were designated as sample locations 9106-0006-017F and 9106-0006-018F.

The sample results are presented in Table 6 below.9106-0006-017F 2.34E-02 1.44E-02 9106-0006-018F 5.69E-02 1.20E-01 6.14E-03 5.27E-02 2.23E-03 I (1) The Operational DCGLs from Table 2 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 7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis.

Two (2) of the samples were selected for analysis, which Revision 0 13 Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD exceeds the 5% minimum required by the LTP. 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. " For one (1) of the split-sample comparisons (9106-0005-01 8F/S), Cs- 137 was found to not meet the comparison criterion; however, this nuclide may not be present in a particulate form and, therefore, is not necessarily an indicator of a non-homogenous mixing of the soil matrix. K-40, a natural radioisotope, was also found not to be present at an acceptable level of agreement, so the comparison issue was dispositioned to the Condition Report (CR) process, to resolve the issue. The issue is not believed to affect the outcome of the FSS for the following reasons:* The other quality control split sample comparison (9106-0006-007F/S) was found to meet the agreement criteria." The balance of quality control samples for the discharge canal area numbering some thirty-six (36) samples were found to be in acceptable agreement." The sediment samples were found to be at approximately fifteen (15)percent of the nineteen (19) mrem/yr DCGL.The sample analysis vendor, General Engineering Laboratories (GEL) -Charleston, South Carolina, 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 area extent was bounded by taking four (4) confirmatory samples, one (1) in each direction of the compass, two (2) meters distant from the elevated sample location.

The gamma spectroscopy and Sr-90 results are included in Table 10.005F 005B 1.14E-01 4.36E-01 5.01E-03 1.94E-01 005C 3.17E-01 8.21E-01 7.38E-03 3.83E-01 005D 1.03E-01 1.48E-01 4.46E-04 7.67E-02 (1) The Operational DCGLs from Table 2 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 Revision 0 14 Revision 0 14 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD The confirmatory results demonstrate that no measurements exceed 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 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, " 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 Sign Test shows that the survey unit passes FSS.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 sample 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 change to the original LBGR to maintain the number of samples at fifteen (15) to meet the Operational DCGL. However, the value of LBGR is less of 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 release criteria with adequate power as required by the DQOs.Revision 0 15 Revision 0 15 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD The range of the data, about 3.8 standard deviations, was not unusually large.The difference between the mean and median was 34% 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 2.14.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES The anomalies associate with the disagreement between the field splits at sample location (9106-0006-018F) has been discussed in Section 7. The issue was referred to Condition Report (CR-06-0223).

No other anomalies were identified for this survey unit.13. CONCLUSIONS Survey Unit 9106-0006 has met the final DQOs of the FSS. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

Elevated Measurement Comparison and remediation was not required.The sample data passed the Sign Test. The null hypothesis was rejected.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 Class 2.The dose contribution from sediment is 2.8 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 that from sediment, will not exceed 2.8 mrem/yr Total Effective Dose Equivalent (TEDE).Revision 0 16 Revision 0 16 DISCHARGE CANAL SURVEY UNIT 9106-0006 RELEASE RECORD 14.

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.65 General Narrative Page 1 of 105 CASE NARRATIVE For CONNECTICUT YANKEE RE: Soil PO# 002332 Work Order: 168404 SDG: MSR #06-0652, 06-0675, 06-0687, 06-0688, 06-0707, 06-0743, 06-0755 August 15, 2006 Laboratory Identification:

fl I Comments/Corrective Actions: The agreement level for Cs-137 results may be explained by differences in realtive quantities of organic material constiuent to each sample. This does not necessarily indicate a problem with the sample preparation methodology.

On the other hand, the agreeement level for K-40 results may indicate an incomplete mixing of the sample aliqot during on-site sample prep. In consideration of Sr-90 results, guidance for agreement ranges, obtained from USNRC Inspection Procedure 84750, does not address resolution ratios less than 4, therefore, a determination of acceptability for such rations cannot be made.
