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 completely surrounded by Discharge Canal Survey Unit 9106-0007. The survey unit comprises the canal sediments to the depth of three feet from the top of the sediment layer or the original construction depth. This survey unit is bounded by reference coordinates E022 through E029 and by S133 through S143 (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 9106-0015 as Class I in June 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 "walk-down." e) Formal or informal interviews with cognizant personnel. A review of the IOCFR50.75(g)(I) 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, 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 Revision 0 3 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD fraction of the DCGLs for those nuclides that could be identified by gamma spectroscopy. (refer to NE-86-RA-1 142 dated 11-13-86). None of the available historical information reviewed would support a conclusion that any residual activity in this survey unit is likely to be present at concentrations greater than the respective DCGLs.Additional information was provided by several historical documents, including the "Results of Scoping Survey", (completed 9/1/98), the "Historical Site Assessment", and the HSA Supplement (dated 6-30-00). These documents presented the results of several sediment samples taken in 1997. These sample results indicated concentrations of 0.5 pCi/g for Co-60, 0.024 pCi/g for Cs-134 and 0.722 pCi/g for Cs-137.The survey area that constitutes Survey Unit 9106-0015 was initially a portion of Class 2 Survey Unit 9106-0007. However, upon reviewing the FSS data for Survey Unit 9106-0007, it was determined that one (1) sample exceeded the Operational DCGL for the area. This required that a portion of Survey Unit 9106-0007 be reclassified as a Class I survey unit. This was done and the newly created survey unit was designated 9106-0015. The FSS data taken in association with the initial FSS design for Survey Unit 9106-0007, was deemed to be appropriate for characterization data for Survey Unit 9106-0015. This consisted of fifteen (15) sediment samples taken from fifteen (15) locations. All of the samples were analyzed by gamma spectroscopy and for Sr-90. In addition, two (2) of these samples were analyzed for all Hard-to-Detect (HTD) nuclides. The results indicated that the radionuclides of concern identified for FSS planning purposes were Cs-137, Co-60 and Sr-90 (refer to Table 1).Tobie I Baisic staitisticaI Q uantities For Cs-137, Co-60 and Sr 90~P~arfromethe Charcteizaio ' S C t-60Se9 C Minimum Value: -1.62E-02 -1.46E-02 -9.81E-03 Maximum Value: 6.42E-01 3.09E+00 4.04E-02 Mean: 2.25E-01 4.90E-01 8.03 E-03 Median: 2.21 E-0 1 1.20E-0 1 7.30E-03 Standard Deviation: 2.22E-01 8.32E-01 1.08E-02 NOTE: 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 The FSS Engineer performed a visual inspection and walk-down 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 significant probability for residual radioactivity to be present in this survey unit in Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD concentrations greater than the Operational DCGLs justifying a final survey unit classification of Class 1 (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 9106-0015 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 I shows the mathematical relationship between the three (3) components and the total dose.Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD 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 groundwater dose values discussed above.This survey unit is not affected by existing groundwater, (reference CY memo ISC 06-024). Therefore, dose contribution from existing groundwater is zero (0) mrem/yr TEDE.This survey unit is not 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 contribution from future groundwater is zero (0) mrem/yr TEDE.Equation 2: 19 mrem/yrTotal= 19 mrem/yrsoi 1+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 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 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD Taible 2 -Radionuclide Specific Base Case Soil DCGL, Operational DCG.Is~~~ >iand I eqiii, 4 d Minimnum DetectnbIe Concentitotjs~ Radionuclide" D 'Base(' Cse Sol 'Operational DCG(L< Requir-ed MWC 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+O1 1.32E+01 6.96E-01 Fe-55 2.74E+04 2.08E+04 1.10E+03 Co-60 3.81E+00 2.90E+00 1.52E-01 Ni-63 7.23E+02 5.49E+02 2.89E+O1 Sr-90 1.55E+00 1.18E+00 6.20E-02 Nb-94 7.12E+00 5.41 E+00 2.85 E-01 Tc-99 1.26E+01 9.58E+00 5.04E-0 I Ag- 108m 7.14E+00 5.43 E+00 2.86E-01 Cs-134 4.67E+00. 355E+00 1.87E-01 Cs-137 7.91 E+00 6.01 E+00 3.16E-01 Eu-152 1.01E+01 7.68E+00 4.04E-01 Eu- 154 9.29E+00 7.06E+00 3 .72E-0 I Eu-155 -).92E+02 2.98E+02 1.57E+01 Pu-238 2.96E+01 2.25E+01 1.18E1+00 Pu-239/240 2.67E+01 2.03 E+O 1 -1.07E+00 Pu-241 8.70E+02 6.61E+02 3.48E+O1 Am-241 () 2.58E+01 1.96E+01 1.03E+00 Cm-243/244 2.90E+01 2.20E+01 1.1 6E+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. 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 Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0015 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.The Elevated Measurement Comparison (EMC) consists of comparing each measurement from the survey unit with the investigation levels discussed in Section 4 (and presented in Table 4). As stated in Section 5.8.3 of the LTP, any measurement from the survey unit that is greater than an investigation level indicates an area of relatively high concentrations that should be investigated, regardless of the outcome of the nonparametric statistical tests. Thus the use of the EMC against the investigation levels may be viewed as assurance that unusually large measurements will receive proper attention regardless of the outcome of those tests and that any area having the potential for significant dose contributions will be identified. The LTP (by way of Equation 5-3 1) states that if residual radioactivity exists in an isolated area of elevated activity in addition to residual radioactivity distributed relatively uniformly across a survey unit, the unity rule will be used to ensure the total dose is within the release criterion. This is demonstrated in equation 3.Equation 3.: 6 + Celevated 6 <1 DCGLW (AreaFactor) x DCGL W Where: 6 =average concentration outside the elevated area, Celevaled = average concentration in the elevated area.A separate term will be used in Equation 3.0 for each elevated area in a survey unit.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 Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD was chosen for the design 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 3 of this Release Record.The DQO process determined that Cs-137, Co-60 and Sr-90 were the radionuclides of concern (refer to Section 2). 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 EMC applies to this survey unit since it is a Class I area.The Sign Test was selected as the non-parametric statistical test to demonstrate that the null hypothesis was rejected. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. In addition, this approach is conservative since it includes background Cs-137 as part of the sample set.The number of sediment samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.394 to maintain the relative shift (A/a) in the range of I and 3. The resulting relative shift was 1.1. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.This indicates that the survey unit has a high probability of rejecting the null hypothesis, assuming that the characterization data are representative of the FSS results. Survey design specified twenty-eight (28) sediment core samples for non-parametric statistical testing.The grid pattern and locations of the sediment samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14,"Identifying, and Marking Surface Sample Locations for Final Status Survey. " Revision 0 9 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD 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 I 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.Table 3 -Sample Measurement Locations with Associated GPS Coordinates De>+/-'i:sign Northing [Easting 9106-0015-OO1F 235153.65 672480.81 9106-0015-002F 235133.21 672445.41 9106-0015-003 F 235133.21 672469.01 9106-0015-004F 235133.21 672492.61 9106-0015-005F 235112.77 672410.01 9106-0015-006F 235112.77 672433.61 9106-0015-007F 235112.77 672457.21 9106-0015-008F 235112.77 672480.81 9106-0015-009F 235112.77 672504.40 9106-0015-01 OF 235092.34 672421.81 9106-0015-01 IF 235092.34 672445.41 9106-0015-012F 235092.34 672469.01 9106-0015-013F 235092.34 672492.61 9106-0015-014F 235092.34 672516.20 9106-0015-015F 235071.90 672433.61 9106-0015-016F 235071.90 672457.21 9106-0015-017F 235071.90 672480.81 9106-0015-018F 235071.90 672504.40 9106-0015-019F 235071.90 672528.00 9106-0015-020F 235051.46 672445.41 9106-0015-021F 235051.46 672469.01 9106-0015-022F 235051.46 672492.61 9106-0015-023F 235051.46 672516.20 9106-0015-024F 235051.46 672539.80 9106-0015-025F 235031.02 672457.21 9106-0015-026F 235031.02 672480.81 9106-0015-027F 235031.02 672504.40 9106-0015-028F 235010.58 672469.01 Five (5) 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.

The two (2) samples exhibiting the highest observed radionuclide concentrations by gamma analyses were also selected.The results of one (1) additional sample, number 9106-0007-017F, were included in this report as a result of the investigation that was conducted based on the results of the sample analyses.The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " required the collection of three (3) 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 as specified by the LTP.Section 5.7.3.2.6 of the LTP specifies that scanning is not required for the FSS of the Discharge Canal.

SURVEY IMPLEMENTATION Final Status Survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0021. The WP&IR package included a detailed FSSP, job safety analysis, job planning checklist and related procedures for reference. Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The "Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.Measurement locations were identified in North American Datum (NAD) 1927 coordinates that were supplied to the sampling vendor, Ocean Surveys, Inc.(OSI) of Old Saybrook, Connecticut. Discharge Canal sampling was accomplished using direct push technology to collect composite samples of 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 twenty-eight (28) 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. Five (5) samples (9106-0015-002F, 9106-0015-004F, 9106-0015-015F, 9106-0015-018F and 9106-0015-021 F) of the total number of samples identified for non-parametric testing were selected for HTD radionuclide analysis by the off-site laboratory. A sixth sample, 9106-0007-017F, was originally collected and analyzed as part of Survey Unit 9106-0007. However, since the sample results exceeded the limits for a Class 2 survey unit, Survey Unit 9106-0015, a Class 1 survey unit, was created. The results of sample number 9106-0007-017F were included in this survey unit as a investigative sample result that required Revision 0 12 Revision 0 12 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD additional sampling and analysis and not for non-parametric testing purposes (refer to Section 8).The implementation of quality control measures included the collection of three (3) split samples at locations (9106-0015-005F, 9106-0015-012F and 9106-0015-01 8F for comparative analysis by the off-site laboratory.

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

The laboratory analyzed the twenty-eight (28) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy. Sr-90 was analyzed by liquid scintillation analyses. All analyses were performed to the required MDC.Cs-137 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in twenty-four (24), Co-60 was positively identified in twenty-one (21) and Sr-90 was positively identified in five (5) of the twenty-eight (28) samples.Several other radionuclides, which were positively identified, could be de-selected or excluded using the 5% and 10% rule described in Section 5.4.7.2 of the LTP.None of the sample results exceeded the Operational DCGL or required further investigation. A summary of the sample results is provided in Table 5.Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD 9106-0015-0031F 4.67E-02 1.42E-0 1 -3 .33E-03 5.319E-02 1.08E-0 1 9106-0015-004F -8.56E-03 9.74E-03 1.98E-02 1.86E-02 1.88E-02 9106-0015-005F 5.89E-02 9.29E-04 1.33E-02 2.13E-02 7.54E-02 9106-0015-006F 3.22E-01 3.50E-01 8.64E-03 1.82E-01 2.36E-01 9106-0015-007F 2.85E-01 3.55E-01 2.98E-03 1.72E-01 2.26E-01 9106-0015-008F 2.15E-0I 3.49E-01 1.05E-02 1.65E-01 2.19E-01 9106-0015-009F 1.1 9E-02 3.23E-02 1.55E-02 2.61 E-02 8.03E-02 9106-0015-01OF 2.53E-01 0.OOE+00 3.71E-03 4.52E-02 9.93E-02 9106-0015-011 F 4.93E-01 3.96E-01 1.88E-02 2.34E-01 2.88E-01 9106-0015-012F 3.47E-01 6.55E-01 3.27E-03 2.86E-0I 3.40E-01 9106-0015-01 3F 4.43E-01 7.05E-01 5.OOE-03 3.21 E-01 3.75E-01 9106-0015-014F 4.43E-02 4.32E-02 2.22E-02 4.09E-02 9.90E-02 9106-0015-015F 2.08E-01 7.07E-02 2.11 E-02 7.67E-02 4.79E-02 9106-0015-016F 3.02E-01 1.01 E-01 -2.59E-03 8.29E-02 1.37E-01 9106-0015-017F 4.74E-0 I 2.90E-01 4.49E-03 1.83E-01 2.37E-01 9106-0015-018F 3.54E-01 1.1 6E+00 -1.1 5E-02 4.49E-01 4.72E-01 9106-0015-019F 9.01 E-02 2.38E-01 9.59E-03 1.05E-01 1.59E-01 9106-0015-020F 9.79E-02 2.03E-01 -8.28E-03 7.93E-02 1.33E-01 9106-0015-021 F 3.98E-01 0.OOE+00 -1.17E-02 5.64E-02 7.43E-02 9106-0015-022F 3.46E-01 6.97E-01 2.53E-03 3.OOE-01 3.54E-01 9106-0015-023F 3.28E-01 1.06E+00 -1.20E-02 4.1 OE-0 I 4.64E-01 9106-0015-024F 6.71E-02 1.15E-01 2.52E-02 7.20E-02 1.03E-01 9106-0015-025F 1 .17E-02 -3.63E-03 1.28E-02 1.1 5E-02 4.25E-02 9106-0015-026F 3.23E-01 5.75E-02 6.5 1E-03 7.90E-02 1.1 OE-01 9106-0015-027F 2.73E-0I 1.39E-01 3.14E-03 9.60E-02 1.27E-0 I 9106-0015-028F 4.90E-03 -3.79E-03 -1.53E-02 -1.33E-02 1.77E-02 (1) The Operational DCGLs from Table 2 are 6.01 pCi/g for Cs-137, 2.90 pCi/g for Co-60, 1.18 pCi/g for Sr-90; the Operational DCGL for C-14, a HTD radionuclide identified in one (1)or more FSS samples analyzed for HTD, is 4.30 pCi/g, These values were used in conjunction with the unity rule to achieve nineteen (19) mrem/yr TEDE.(2) This column is the sum of the DCGL unity fraction from identified radionuclides of concern and HTD isotope(s) exceeding the 5%/10% rule for one (1) or more FSS samples. For those samples not measured for HTD isotopes, an average calculated value of 3.1% of the DCGL was added to each sample.The off-site laboratory also processed a total of five (5) samples, collected for non-parametric testing, for HTD analysis as required by the sample plan.Sample number 9106-0007-017F was including in this report for the following reasons; because the sample result exceeded the Operational DCGL, the sample Revision 0 14 Revision 0 14 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD result precipitated the creation of this survey unit, and as a part of the investigation relating to this sample to ensure that it complies the DCGLEMC comparison Test of Section 5 of the LTP.The analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC.Three (3) of the five (5) samples collected for non-parametric testing, and analyzed for HTD radionuclides, met the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty. Each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10%rules, with the exception of one (1) sample, 9106-0015-002F, which exceeded the 10% rule for a total of four (4) HTD radionuclides.

These values were used in conjuncture with the unity rule to achieve nineteen (19) mrem/yr TEDE.(2) This column is the sum of the DCGL unity fraction from identified HTD radionuclides identified in one (1) or more FSS samples.(3) Sample number 9106-0007-017F was the initiating sample for the generation of this survey unit. This sample was analyzed for HTD radionuclides as part of the investigative process for an EMC. The results of the sample analyses of 9106-0007-017F were not included in the results of sample analyses conducted for non-parametric testing. (sample 9106-0007-017F was not taken as a part of the sample design for this survey unit).7. QUALITY CONTROL The three (3) split samples taken for QC were analyzed by the off-site laboratory. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 and as detailed in HNP Procedure RPM 5.1-24,"Split Sample Assessment for Final Status Survey. " Revision 0 15 Revision 0 '5 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD One (1) split-sample (9106-0015-005F/S) did not meet the comparison criterion for Cs-137. A possible cause for this anomaly could be the presence of Cs-137 tightly bound to organic material in the sample aliquot. This distribution of material does not lend itself to homogenous mixing in a sediment matrix and, therefore, is not necessarily an indicator of inadequate sampling or sample preparation methodology. Additionally, since the resolution ratios for both Co-60 and Sr-90 were less than four (4), and the USNRC Inspection Procedure 84750 does not give guidance on resolution ratios below four (4), a determination on acceptability for such ratios can not be made. In this sample, K-40, a natural radioisotope, was found to be present at an acceptable level of agreement; therefore, the comparison was determined to be acceptable. For the other two (2) QC split samples (9106-0015-012F/S & 9106-0015-018F/S), there was an acceptable level of agreement between the samples for Cs-137, Co-60 and K-40. However, the resolution ratio for Sr-90 was less than four (4), and the USNRC Inspection Procedure 84750 does not give guidance on resolution ratios below four (4), a determination on acceptability for such rations can not be made.The sample analysis vendor, GEL, maintained quality control and quality assurance plans as part of normal operation. Refer to Attachment 2 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS One (1) sample result, that led to the creation of this survey unit, was found to exceed the Operational DCGL of nineteen (19) mrem/yr, exceeding the investigation level from Table 4. Thus an investigation was required to determine compliance with Equation 3 of Section 3.The first step in determining whether compliance with the EMC unity rule is to determine the area extent of the elevated measurement region. This was done by taking investigation samples at a distance of one (1) meter in each of the four (4) compass directions about the elevated sample point (9106-0007-017F). When these sample results were determined to be below the investigation levels specified in Table 4, the area was said to be bounded.The area of the elevated measurement location (also the area used to determine area factors) was conservatively calculated by assuming the area was a circle with a radius equal to the most distant bounding measurement location. This was done using actual GPS log data. This was the most prudent approach since maneuvering the sampling vessel to obtain samples within such closely spaced locations imposes unusually high positioning precision. Table 7 provides sample measurement location information (in NAD 1927) and distances from sample location 9106-0007-017F.

These values were not subtracted from the mean activity of the elevated area, which is conservative. Revision 0 17 Revision 0 17 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD 9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria to be unnecessary and that the remaining residual radioactivity in soil was ALARA.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN The survey was designed to ten (10) mrem/yr TEDE which was conservative and necessary at the time of FSS planning. It is no longer required as the total dose from existing and future groundwater has been established. The dose for soil used to demonstrate compliance with the LTP and CTDEP criteria is nineteen (19) mrem/yr TEDE as discussed in Section 2 of this Release Record.11. DATA QUALITY ASSESSMENT (DQA)The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment." The sample design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs.The evaluation of the Sign Test results indicates that the survey unit passes the unrestricted release criterion, thus, the null hypothesis is rejected.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 1.The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). The standard deviation was slightly more than the value used for the survey design. This is represented by the shift in the retrospective power curve as shown in Attachment 2f. This would indicate a need to change the original LBGR in order to maintain the number of samples at twenty-eight (28) to meet the Operational DCGL. However, the value of LBGR is not a critical issue as the survey unit has passed the statistical test, and the mean and median values are well below the Operational DCGL when used in conjunction with the unity rule. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criterion with adequate power as required by the DQOs The range of the data, about 3.47 standard deviations, was not unusually large.The difference between the mean and median was 42.2% 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 1.09.Revision 0 18 Revision 0 18 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD The survey area had one (1) elevated measurement location, which was evaluated using the unity EMC test. This resulted in a passing value of 0.264, which is significantly below unity.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES The anomalies associated with a disagreement on one (1) of the field splits has been discussed in Section 7. The source of the disagreement for Cs-137 is believed to be due to Cs-137 being tightly bound to organic materials in the sample media. Such a physical form does not lend itself to homogenous mixing in a sediment matrix.13. CONCLUSION Survey Unit 9106-0015 has demonstrated compliance with the dose based, unrestricted release criterion. The sample data passed the Sign Test and the null hypothesis was rejected. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Reclassification and remediation of this survey unit was not required.Graphical representation of data indicates some positive skewness that is probably due to localized differences in particulate deposition rates, hydraulic velocity and sedimentation rates. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit was properly designated as a Class I survey unit.The dose contribution from sediment in this survey unit is 3.1 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 groundwater sources is bounded by zero (0) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no concrete foundations or footings containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component is, therefore, zero (0) mrem/yr TEDE.The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity, will not exceed 3.1 mrem/yr Total Effective Dose Equivalent (TEDE).Revision 0 19 DISCHARGE CANAL SURVEY UNIT 9106-0015 RELEASE RECORD 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. 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.37 CASE NARRATIVE For CONNECTICUT YANKEE RE: Soil PO# 002332 Work Order: 170683 SDG: 170683 September 6, 2006 Laboratory Identification: General Engineering Laboratories, LLC Mailing Address: P.O.
