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 9106-0006 is to the north (called north as orientated with the north to south flow of the Connecticut River), survey area 9521 is to the east, Discharge Canal Survey Unit 9106-0008 is to the south and Discharge Canal Survey Unit 9106-0013 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.A distinguishing feature of this Survey Unit is that it completely surrounds Class 1 survey unit 9106-0015.

Survey Unit 9106-0015 was created in response to receiving a sample result (9106-0007-017F) which exceeded the design limits for a class 2 Survey Unit. The design changes made to accommodate the removal of this 1,170 m 2 area from the initial design for Survey Unit 9106-0007 is discussed in section 4.This survey unit is bounded by reference coordinates E026 through E032 by S122 through S140 (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 9106-0007 as Class 2 in May 2006.The "Classification Basis Summary" conducted for this survey unit consisted of: a) A review of the 10CFR50.75 (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." Revision 0 3 Revision 0 3 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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. In 1986, samples of the 1979 dredge spoils area and canal sediment were taken. The sample analyses indicated that the concentrations of Cs-137, Co-60 and other radionuclides were a small fraction of the DCGL for those nuclides that could be identified by gamma spectroscopy. (refer to NE-86-RA-1142 dated 11-13-86).

None the available information indicates that the residual activity present is likely to be above the DCGL for the area.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, 0.024pCi/g for Cs-134 and 0.722 pCi/g for Cs-137.An initial characterization survey was implemented during April and May of 2004. Six (6) samples from three (3) locations were obtained by biased sampling throughout the area. The samples were analyzed off-site by gamma spectroscopy and with radiochemical analyses for Sr-90 and Tritium. Hard-to-Detect analyses were also conducted on one (1) of the six (6) samples. The only plant-related dosimetrically significant radionuclides identified in the samples were Cs-137, Co-60 and Sr-90. No samples indicated radioactive material in quantities above the ten (10) mrem/yr design DCGL. Co-60 accounted for the majority of the dose in these samples with a maximum concentration of 0.44 pCi/g.A final characterization was performed by Site Closure personnel in April of 2006. Six (6) sediment samples from six (6) locations were taken. All of the samples were analyzed by gamma spectroscopy.

Based on the initial and final characterization results, the radionuclides of concern identified in the sample data for FSS planning purposes were Cs-137, Co-60 and Sr-90. Since HTD analyses were not performed for all radionuclides of interest during characterization, additional HTD analyses were performed as a part of the FSS.The statistics for each of the radionuclides of concern are listed in Table 1.Revision 0 4 Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD Table 1 -Basic Statistical Quantities for Cs-137,,Co-6)0 and Sr-90 fromn thle tharacterizaition SurveyýMinimum Value: -8.61E-02 2.15E-03 2.44E-02 Maximum Value: 5.3 8E-01 4.36E-01 5.25E-02 Mean: 1.84E-01 1.35E-01 3.61E-02 Median: 1.79E-01 7.32E-02 3.55E-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 9106-0007 did not exceed the release criteria specified in the LTP and that the potential Revision 0 5 Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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.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 not affected by either existing or future groundwater (reference CY memo ISC 06-024). Therefore, dose contribution from both groundwater components is zero (0) mrem/yr TEDE, based on field data.Equation 2: 19 mrern/yrTotal=

19 mrem/yrsoil+0 mrem/yrExisting GW+O 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 Revision 0 6 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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.T~able 2 -Radionuclide Specific ~Base Cs olD';, prtoa C~and Required Minimumn Detectable Concentrations, Radionuclide ( Base Case Soil Operational DML, Reqnihred MDC-H-3 4.12E+02 3.13E+02 1.65E+01 C-14 5.66E+00 4.30E+00 2.26E-01 Mn-54 1.74E+01 1.32E+01 6.96E-0I Fe-55 2.74E+04 2.08E+04 1.1 OE+03 Co-60 3.8 1 E+00 2.90E+00 1.52E-01 Ni-63 7.23E+02 5.49E+02 2.89E+OI Sr-90 1.55E+00 1.18E+00 6.20E-02 Nb-94 7.12E+00 5.41E+00 2.85E-01 Tc-99 1.26E+01 9.58E+00 5.04E-0I 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-0I Eu-152 1.01E+O1 7.68E+00 4.04E-0I 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+OI 2.25E+01 1.1 8E+00 Pu-239/240 2.67E+O I 2.03E+01 1.07E+00 Pu-241 8.70E+02 6.61 E+02 3.48E+O1 Am-241 () 2.58E+O1 1.96E+01 1.03E+00 Cm-243/244 2.90E+O1 2.20E+O1 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.

Revision 0 7 Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Initial characterization was performed in April of 2004 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.

Subsequently, 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.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 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.Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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 0.735 to maintain the relative shift (A/G) 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 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.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 9106-0007 RELEASE RECORD Twtable 3 -Sample Measurement Locations with ssoiated GPS Coordinates D~esignationi

Samples locations 9106-0007-009F and 9106-0007-OIOF were found to be on dry land, consequently, they were randomly relocated using the VSP software to two (2) new locations designated as 9106-0007-016F and 9106-0007-017F.

When the sample result for 9106-0007-017F was received from the off-site laboratory, it was determined that the sample exceeded the Operational DCGL of nineteen (19) mrem/yr (the sample's activity was equivalent to 22.4 mrem/yr).

Since sample results cannot exceed the DCGL in a Class 2 area, an approximately square rectangle of 1,170 m2 was removed from the footprint of the FSS design for Survey Unit 9106-0007.

A consequence of removing Survey Unit 9106-0015 from Survey Unit 9106-0007 was that four (4) sample locations were now located outside the boundary of Survey Unit 9106-0007, and needed to be relocated.

The samples locations were relocated using randomly generated locations from the VSP software.

The four locations removed from the FSS survey were locations 9106-0007-006F, 008F, 016F and 017F. These were replaced with sample locations 9106-0007-018F through 9106-0007-02 1F.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 Revision 0 10 Revision 0 10 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD"RAND" function.

The two (2) samples exhibiting the highest observed radionuclide concentrations by gamma analyses were also selected.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. Table 4 provides a synopsis of the survey design.Table 4 -Synopsis of IheScie-,'nr

I.e. Survey Unit 9106-0015 was a part of Survey Unit 9106-0007 when the grid sizes were calculated.

(3) The allowable dose for soil in this survey unit is nineteen (19) mrem/yr TEDE as the bounding dose from existing and future groundwater has been established based on field data (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 Revision 0 I1I Revision 0 11 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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 Survey, 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 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 (1-INP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey ". Samples were controlled, transported, stored, and transferred to the off-site laboratory using COC protocols.

Four (4) samples (9106-0007-001F, 9106-0007-002F, 9106-0007-014F and 9106-0007-021F) were selected for HTD radionuclide analysis by the off-site laboratory.

The implementation of survey specific quality control measures included the collection of two (2) split samples at locations 9106-0007-004F and 9106-0007-013F 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.Revision 0 12 Revision 0 12 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD Cesium-137 was identified in ten (10), Co-60 was identified in nine (9) and Sr-90 in two (2) of the fifteen (15) samples. The results reported for the remaining sample analyses indicated that activity was present at levels approaching or below the established detection limit in the remaining samples collected and analyzed for non-parametric testing.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 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.Some of the HTD radionuclides met the acceptance criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty) in more than one 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.

Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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 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. " Each of the comparisons met the acceptance criteria.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 None of the sample results exceeded the operational DCGL, thus no investigations were required.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.Revision 0 14 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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 the 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.The range of the data, about 3.6 standard deviations, was not unusually large.The difference between the mean and median was 25% 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 1.37.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES The configuration of this survey unit was changed from its initial design to a smaller Class 2 Survey Unit and a new Class 1 Survey Unit (Survey Unit #9106-0015) that had a surface area of approximately 1,170 in 2.The new survey unit became necessary when the sample result for 9106-0007-017F was received from the off-site laboratory, it was determined that the sample exceeded the Operational DCGL of nineteen (19) mrem/yr (the sample's activity was equivalent to 22.4 mrem/yr).

Since sample results cannot exceed the DCGL in a Class 2 area, an approximately square rectangle of 1,170 m2 was removed from the footprint of the FSS design for Survey Unit 9106-0007.

Addendum 1 to the FSS plan was implemented to address the changes to the plan associated with the establishment of a new Class 1 Survey Unit and the relocation of four (4) sample points that would no longer reside within Survey Unit 9106-0007.

In accordance with Addendum 1, four (4) new sample locations were identified and sampled within Survey Unit 9106-0007.

No other anomalies were noted within this survey unit.13. CONCLUSION Survey Unit 9106-0007 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.Revision 0 15 Revision 0 15 DISCHARGE CANAL SURVEY UNIT 9106-0007 RELEASE RECORD 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 2.2 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.This survey unit is unaffected by existing groundwater (reference CY memo ISC 06-024). It has been determined that the dose contribution from groundwater sources is zero (0) mrem/yr TEDE.This survey unit is also 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 2.2 mrem/yr Total Effective Dose Equivalent (TEDE).14.

Cheryl: Per our earlier discussion, please analyze samples 9106-0007-014F and 9106-0007-021 F to the FSSALL protocol per MSR 06-1310, with a 7 day TAT. Each of these samples were previously tested for FSSGAM and Sr-90 under MSR 06-0730 and MSR 06-1035 respectively.

Thank you for your assistance.

Concentrations are <SX the RL A The TIC is a suspected aldol-condensation product B Target analyte was detected in the associated blank B Metals-Either presence of analyte detected in the associated blank, or MDL/IDL < sample value < PQL BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample d 5-day BOD-The 2:1 depletion requirement was not met for this sample E Organics-Concentration of the target analyte exceeds the instrument calibration range E Metals-%difference of sample and SD is >10%. Sample concentration must meet flagging criteria H Analytical holding time was exceeded h Preparation or preservation holding time was exceeded J Value is estimated N Metals-The Matrix spike sample recovery is not within specified control limits N Organics-Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based on nearest internal standard response factor N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the reporting limit UI Gamma Spectroscopy-Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound Z Paint Filter Test-Particulates passed through the filter, however no free liquids were observed.GENERAL ENGINEERING LABORATORIES, LLC a Member of THE GEL GROUP, INC.P.O.
