16 14.1 Attachment 1 -Figures (6 pages including cover)14.2 Attachment 2 -Sample and Statistical Data (194 pages including covers)Revision 0 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9106-0003 (Discharge Canal) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 8,292 m 2 ( 2.05 acres) of water covered sediment in an area located approximately 0.28 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 which includes two (2) permanent wetland areas for FSS purposes.

With"called north" oriented with the north to south flow of the Connecticut River, the survey unit is bounded as follows: Discharge Canal Survey Unit 9106-0002 is to the north, land surface area Survey Unit 9521 is to the east, Discharge Canal Survey Unit 9106-0004 is to the south and Survey Area 9520 is to the west. The survey unit comprises the canal sediments to the deeper of three (3)feet or the original construction depth. It extends up the canal banks to the mean high water level.The reference coordinates associated with this survey unit are E010 through E015 by S084 through S092 (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 9106-0003 as Class 2 in April 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 1 OCFR50.75(g)(1) database report identifies 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, contamination Revision 0 3 Revision 0 3 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD 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 of the available historical information reviewed would support a conclusion that any residual activity in this survey unit was 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.A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" provided no additional information pertinent to classification.

Characterization was performed by Site Closure personnel in April and May of 2004 to obtain the necessary data of sufficient data quality for final status survey (FSS) planning purposes.

Fifteen (15) samples were initially obtained by biased sampling throughout the area. The samples were analyzed off-site using gamma spectroscopy.

Hard-to-Detect analyses were also conducted on two (2) of the fifteen (15) samples. The only plant-related dosimetrically significant radionuclides identified in the samples were Cesium- 137 and Cobalt-60 (refer to Table 1).Table I -Basic 'Statitical Cs-137 and Co-60 fromn the ChrceiainSte Minimum Value: -6.28E-03

1.32E-01 3.85E-01 NOTE: The Operational DCGLs are 5.38 pCi/g for Cs-137, 2.59 pCi/g for Co-60; these are used in conjunction with the unity rule to achieve 17 mrem/yr TEDE The FSS Engineer performed a visual inspection and walkdown during May 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

Based upon the historical information and the results of radiological surveys performed during characterization, it was concluded that there was a low Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD 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 9106-0003 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 and spread for the planting of crops per the Resident Farmer Scenario.Consequently, the soil DCGLs are directly applied to the canal sediment media which are sampled by coring to a nominal depth of three (3) feet.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 Revision 0 5 Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD residual radioactivity.

Equation 1 shows the mathematical relationship between the three (3) components and the total dose.Equation 1: HTotal=HSoil (sediment)

+ HExisting GW + HFuture GW The total dose under the LTP criteria is twenty-five (25) mrem/yr TEDE from all three 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 affected by existing groundwater (reference CY memo ISC 06-024). The dose contribution from existing groundwater is bounded to be less than two (2) mrem/yr TEDE, based on field data.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no concrete foundations or footings remaining within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contributions from future groundwater, the third component is, therefore, zero (0) mrem/yr TEDE.Equation 2: 19 mrem/yr~otaj=

17 mrem/yrsoi 1+2 mrem/yrExisting GW+O mrem/yrFuture GW The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 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 9 106-0003 RELEASE RECORD 1-1-.5 4.1 bU-t-O 2.80E+02 1.65E+01 C-14 5.66E+00 3.85E+00 2.26E-01 Mn-54 1.74E+01 1.18E+O1 6.96E-0I Fe-55 2.74E+04 1.86E+04 1 .1 OE+03 Co-60 3.81E+00 2.59E+00 1.52E-01 Ni-63 7.23E+02 4.92E+02 2.89E+O1 Sr-90 1.55E+00 1.05E+00 6.20E-02 Nb-94 7.12E+00 4.84E+00 2.85E-01 Tc-99 1.26E+O1 8.57E+00 5.04E-01 Ag- 108m 7.14E+00 4.86E+00 2.86E-01 Cs-134 4.67E+00 3.18E+00 1.87E-01 Cs-137 7.91E+00 5.38E+00 3.16E-01 Eu-152 1.01E+01 6.87E+00 4.04E-01 Eu-154 9.29E+00 6.32E+00 3.72E-01 Eu-155 3.92E+02 2.67E+02 1.57E+01 Pu-238 2.96E+01 2.01E+O1 1.18E+00 Pu-239/240 2.67E+01 1.82E+01 1.07E+00 Pu-241 8.70E+02 5.92E+02 3.48E+O I Am-241 (5) 2.58E+01 1.75E+01 1.03E+00 Cm-243/244 2.90E+01 1.97E+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 seventeen (17) 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.

Characterization was performed in April and May of 2004 as discussed in Section 2. Cesium-137 and Cobalt-60 were found to be the predominate radionuclides of concern. The basic statistical quantities (i.e., mean, standard deviation, median) for Cs-137 and Co-60 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 Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD 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. To assist the FSS Engineers when preparing survey plans for FSS, guidance is provided in Procedure RPM 5.1-11,"Preparation of Final Status Survey Plans". By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP.Characterization was performed by Site Closure personnel in April and May 2004 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern (refer to Section 3). The sum of fractions or unity rule would be used with the individual Operational DCGLs because multiple radionuclides (Cs-137 and Co-60) were considered in the survey design. Other radionuclides identified during FSS would be evaluated to ensure adequate survey design and compliance with the unity rule.Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of nearby adjacent areas and via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". 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 less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since the survey unit is a Class 2 and discrete, elevated areas of contamination were not expected.The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

This approach was conservative since it included background Cs-137 as part of the sample set.The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.5 to maintain the relative shift (A/a) in the range of 1 and 3. The resulting relative shift was 1.9. 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.Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD Survey design specified sixteen (16) sediment 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.STable 3 -Sampl~e Wasurment Locations N~ith Associated

The location was selected based on its proximity to the outfall of a culvert which drains from a low-lying area along the Independent Spent Fuel Storage Installation (ISFSI) haul road.Although Procedure RPM 5.1-11 specifies that 5% of the samples must be selected for HTD analysis, four (4) sediment samples were analyzed for HTDs, exceeding the percentage required.

Two (2) samples for statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel"RAND" function.

In addition, two (2) samples, which were determined to contribute the greatest dose based on gamma only analyses were also selected Revision 0 9 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD for HTD analyses.

This number of HTD analyses exceeded the 5%requirement.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in Table 2.The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " included the collection of two (2) sediment 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.

Section 5.7.3.2.6 of the LTP specifies that scanning is not required for the FSS of the Discharge Canal. Table 4 provides a synopsis of the survey design.Survey Unit Area d on AutoUAD-LI and Visual Sample Plan calculations Type I and Type 2 errors were 0.05, Number of 16 sigma was 0.257 the LBGR was set to 0.5 Measurements to maintain Relative Shift in the range of I and 3, Relative Shift was 1.9 Grid Spacing 24.5 Based on triangular grid Design DCGL 3.16 pCi/g Cs-137 To achieve 10 mrem/yr TEDE 1.52 pCi/g Co-60 Operational 5.38 pCi/g Cs-137 To achieve 17 mrem/yr TEDE (2) to demonstrate compliance with DCGL 2.59 pCi/g Co-60 Equation 2 of this Release Record Scan Coverage N/A The LTP exempts this area Sediment Investigation 5.38 pCi/g Cs-137 The Operational DCGL meets the LTP Level 2.59 pCi/g Co-60 criteria for a Class 2 survey unit (1) The survey design used a much smaller value for investigation than the Operational DCGL provided by Table 2 as the total dose from existing and future groundwater had not been established at the time of planning the FSS (2) The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as the total dose from existing and future groundwater has been established (reference CY memo ISC 06-024)5. 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.Revision 0 10 Revision 0 10 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD Using GPS coordinates, sample measurement locations were identified in NAD 1927 coordinates that were supplied to the sampling vendor, Ocean Survey Inc. (OSI) of Old Saybrook, Connecticut.

Discharge Canal sampling was accomplished using direct push technology to collect composite samples of bottom and average 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 serves 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 will be accomplished using a global positioning system (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 from the Ocean Surveys, Inc. to site personnel who processed and controlled the samples under Chain-of-Custody (COC). Rinsing of the barrel and associated equipment was performed between sampling events. New aluminum tubes were used to prevent cross-contamination of subsequent samples.The sixteen (16) 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 Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples ".Four (4) samples (9106-0003-004F, 9106-0003-008F, 9106-0003-0014 and 9106-0003-015F) were selected for HTD radionuclide analysis by the off-site laboratory.

Two (2) of these samples (008F and 014F) were selected at random. The others were selected based on being the most dosimetrically significant samples from spectroscopic gamma analyses.One (1) biased sediment sample (9106-0003-017F) was collected and analyzed by the offsite laboratory for gamma spectroscopy.

The implementation of survey specific quality control measures included the collection of two (2) split samples at locations 9106-0003-004F and 9106-0003-01OF 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 sixteen (16) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy.

Gamma Revision 0 I1I Revision 0 11 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD spectroscopy analysis was performed to the required MDC. Gamma spectroscopy results identified some radionuclides meeting the acceptance criteria for detection (i.e., a result greater than two standard deviations uncertainty).

All could be de-selected or excluded using the 5% and 10% rule described in Section 4.Cesium-137 was identified in fourteen (14) and Co-60 was identified in eleven (11) of the sixteen (16) samples.None of the samples exceeded the Operational DCGL. Gamma spectroscopy sample analysis did not require further investigation.

For those samples not measured for HTD isotopes, an average calculated value of 6.1% of the DCGL was added to each sample.The sample location designations of Table 5 are not sequentially inclusive because of the necessity to relocate some samples due to the accessibility of the original sample locations.

Sample number 9106-0003-01 IF could not be sampled due to an obstruction.

Therefore sample number 9106-0003-018F was added as a replacement sample. Sample number 9106-0003-017F was a biased sample location; not part of the non-parametric design.The off-site laboratory also processed four (4) samples for HTD analysis as required by the sample plan. The requested analyses included alpha Revision 0 12 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC. Four (4) 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) sample. Each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10% rules, except for Pu-241. These results are presented in Table 6.<pC/g' I 1Qprational DCG L 9106-0003-004F 8.31 0.014 9106-0003-008F 54.2 0.092 9106-0003-014F 19.0 0.032 9106-0003-015F 6.63 0.011 (1) The Operational DCGL from Table 2 is 592 pCi/g for Pu-241.One (1) biased sample was collected at a location selected by FSS Supervision based on professional judgment and observation.

Gamma spectroscopy analysis was performed by the off-site laboratory to the required MDC. The sample was at 0.8% of the Operational DCGL. No further action or investigations were required (see Table 7).STable 7 -Biased Sample Results"'..s-..

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 exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey. " There was acceptable agreement between the field split results for both of the "split sample" pairs tested.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.Revision 0 13 Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD 8. INVESTIGATIONS AND RESULTS Sample investigation levels were not exceeded for this unit, consequently none were performed.

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 seventeen (17) 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.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 of the sample results was below the design value used. This is represented by a favorable shift in the retrospective power curve as shown in Attachment 2f. This would indicate the retrospective power exceeds the prospective power, indicating that the design sample population was adequate.

The mean and median values are well below the Operational DCGL when used in conjunction with the unity rule.Therefore, the survey unit meets the unrestricted release criterion with adequate power as required by the DQOs.Revision 0 14 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD The range of the data, about 2.98 standard deviations, was not unusually large.The difference between the mean and median was 5.5% of the standard deviation which indicates limited 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 1.2.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES An anomaly was encountered at one non-parametric sample location which could not be sampled due to an obstruction.

The sample (9106-0003-01 IF) was replaced with another randomly generated location (9106-0003-018F).

This is noted in the field notes and other documentation associated with this survey unit.In addition, one HTD radionuclide was reported in concentrations exceeding the 5% and 10% rule for de-selection.

Therefore, the individual Operational DCGLs for Pu-239 was included into sample analyses in conjunction with the unity rule to ensure adequate survey design in accordance with the DQOs. The result of the COMPASS computer run showed adequate power and maintained the original sixteen (16) sediment samples for non-parametric statistical testing.13. CONCLUSION Survey Unit 9106-0003 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 the differences in terrain and the collection of runoff. 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 soil is 4.3 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey unit is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is two (2) 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 0 mrem/yr TEDE.Revision 0 15 DISCHARGE CANAL SURVEY UNIT 9106-0003 RELEASE RECORD 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 6.3 mrem/yr Total Effective Dose Equivalent (TEDE).14.

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.
