SURVEY UNIT DESCRIPTION Survey Unit 9106-0014 (Discharge Canal) is designated as Final Status Survey (FSS) Class 1 and consists of approximately 1,870 m2 (0.46 acres) of water covered sediment in an area located approximately 0.16 miles from the reference coordinate system benchmark used at the Haddam Neck Plant (HNP)(see Attachment 1, Figure 1). The Discharge Canal is a man-made mile long waterway that runs parallel to, and ultimately communicates with the Connecticut River. The Discharge Canal is subdivided into fifteen (15) survey units including two (2) permanent wetland areas for FSS purposes.

The survey unit is bounded as follows: Survey Unit 9106-000lis to the north (called north as oriented with the north to south flow of the Connecticut River), Survey Unit 9521 is to the east, Discharge Canal Survey Unit 9106-0002 is to the south and land Surface Area 9520 is to the west. 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 and it extends up the canal banks to the mean high water level.The survey unit comprises the canal sediments to the depth of three (3) feet from the top of the sediment layer or the original construction depth. This survey unit is bounded by reference coordinates E006 through E010 and by S074 through S080 (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 9106-0014 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)(1) database report identified a number of events that may have impacted this survey unit. Several events indicated the Revision 0 3 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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 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 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.This area was initially a portion of then Class 2 Survey Unit 9106-0001.

Upon reviewing the FSS data for this area it was determined that at least one sample exceeded the seventeen (17) mrem/yr DCGL for the area. This required that the area be reclassified as two (2) Class 1 survey units. In order to optimize the amount of area covered by Class 1 surveys, a portion of Survey Unit 9106-0002 was also included into the southern most area of the two (2) newly designated Class 1 survey units. This was done and the newly created survey unit was designated 9106-0014.

An initial characterization was performed 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 obtained by biased sampling from five (5) locations 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 of the 15 samples. The only plant-related dosimetrically significant radionuclides identified in the samples were Cs-137 and Cobalt-60.

All sample analysis results were below the (ten) 10 mrem/yr target level. Cobalt-60 accounted for the majority of the dose in these samples with a maximum concentration of 1.04 pCi/g.A final characterization survey was performed in May 2006. Samples were collected and analyzed on-site by gamma spectroscopy.

Fifteen (15) sediment samples from fifteen (15) locations were collected and analyzed for radioactive materials.

All of the samples were analyzed by gamma spectroscopy.

A summary of the results are presented in Table 1 below.Revision 0 4 Revision 0 4 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD Table 1 -Basic Statistical Quantities for Cs-137 and Co-60 from the Characterization Survey Parameter Cs-137 (pCi/g) Co-60 (pCi/g)Minimum Value: 2.15E-02 1.03E-03 Maximum Value: 1.57E+00 2.25E+00 Mean: 5.96E-01 6.15E-01 Median: 6.39E-01 3.81E-01 Standard Deviation:

4.96E-01 6.97E-01 NOTE: The Operational DCGLs from Table 2 are 5.38 pCi/g for Cs-137 and 2.59 pCilg for Co-60; these are used in conjunction with the unity rule to achieve seventeen (17)mrem/yr TEDE The FSS Engineer performed a visual inspection and walk-down during June 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 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 I (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 9106-0014 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 Revision 0 5 Revision 0 5 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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 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 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 contribution from future groundwater is zero (0) mrem/yr TEDE.Equation 2: 19 mrem/yrTotal=

17 mrem/yrsoil+2 mrem/yrExisting GW+O mreml/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 Revision 0 6 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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.Table 2 -Radionuclide Specific Base Case Soil DCGL, Operational DCGLs and Required Minimum Detectable Concentrations Radionuclide (1) Base Case Soil Operational DCGL Required MDC DCGL (pCi/g) (2) (pCi/g) (3) (pCi/g) (4)H-3 4.12E+02 2.80E+02 1.65E+01 C-14 5.66E+00 3.85E+00 2.26E-01 Mn-54 1.74E+01 1.18E+01 6.96E-01 Fe-55 2.74E+04 1.86E+04 1.10E+03 Co-60 3.81E+00 2.59E+00 1.52E-01 Ni-63 7.23E+02 4.92E+02 2.89E+01 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+0 1 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 1.01 E+0 I 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+O 1 2.01E+01 1.18E+00 Pu-239/240 2.67E+0 1 1.82E+01 1.07E+00 Pu-241 8.70E+02 5.92E+02 3.48E+01 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) mremlyr 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.

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 7 Revision 0 7 DISCHARGE CANAL SURVEY UNIT 9106-0014 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 and Co-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 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 4.0 (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 5-31) 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 (LTP Equation 5-31):Celevated

<-(-+ <1 DCGLW (AreaFactor) x DCGL W Where:= Average concentration outside the elevated area, C elevated = Average concentration in the elevated area.A separate term will be used in Equation 3.0 for each elevated area in a survey unit.Revision 0 8 Revision 0 8 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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 seventeen (17) mrem/yr TEDE, as discussed in Section 3 of this Release Record.The DQO process determined that Cs-137 and Co-60 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 and Co-60) 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".Radionuclide screening or de-selection is a process where an individual radionuclide or aggregate may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations that are less than 5%for individual radionuclides and that are less than 10% for the aggregate of all radionuclides that are de-selected.

This process was applied to analysis data for this survey unit.The Elevated Measurement Comparison (EMC) applies to this survey unit since it is a Class I area and discrete, elevated areas of contamination are expected.A description of the application of the EMC is provided in section 3.0.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 0.633 to maintain the relative shift (A/cr) in the range of 1 and 3. The resulting relative shift was 1.3. 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 Revision 0 9 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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. For statistical purposes, the survey design specified twenty-one (21)samples were required.

However, due to a special requirement to double the number of statistical samples in this section of the discharge canal, resulting from an agreement with the State of Connecticut Department of Environmental Protection (CTDEP), this number needed to be doubled to forty-two (42)sediment core samples for non-parametric statistical testing.The grid pattern and locations of the sediment samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14,"Identifying, and Marking Surface Sample Locations for Final Status Survey. " Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 1 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.Revision 0 10 Revision 0 10 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9106-0014-OO1F 236196.66 669170.85 9106-0014-002F 236196.66 669194.31 9106-0014-003F 236176.34 669088.74 9106-0014-005F 236176.34 669159.12 9106-0014-006F 236176.34 669182.58 9106-0014-007F 236156.02 669077.01 9106-0014-008F 236156.02 669100.47 9106-0014-009F 236156.02 669123.93 9106-0014-OIOF 236156.02 669147.39 9106-0014-011F 236156.02 669170.85 9106-0014-012F 236135.70 669041.82 9106-0014-013F 236135.70 669065.28 9106-0014-014F 236135.70 669088.74 9106-0014-015F 236135.70 669112.20 9106-0014-016F 236135.70 669135.66 9106-0014-017F 236135.70 669159.12 9106-0014-018F 236115.39 669030.09 9106-0014-019F 236115.39 669053.55 9106-0014-020F 236115.39 669077.01 9106-0014-021F 236115.39 669100.47 9106-0014-022F 236115.39 669123.93 9106-0014-023F 236115.39 669147.39 9106-0014-024F 236095.07 669018.36 9106-0014-025F 236095.07 669041.82 9106-0014-026F 236095.07 669065.28 9106-0014-027F 236095.07 669088.74 9106-0014-028F 236095.07 669112.20 9106-0014-029F 236095.07 669135.66 9106-0014-030F 236074.75 669006.63 9106-0014-031F 236074.75 669030.09 9106-0014-032F 236074.75 669053.55 9106-0014-033F 236074.75 669077.01 9106-0014-034F 236074.75 669100.47 9106-0014-035F 236074.75 669123.93 9106-0014-036F 236054.43 669041.82 9106-0014-037F 236054.43 669065.28 9106-0014-038F 236054.43 669088.74 9106-0014-039F 236054.43 669112.20 9106-0014-040F 236034.12 669053.55 9106-0014-041F 236034.12 669077.01 9106-0014-042F 236034.12 669100.47 9106-0014-043F 236145.72 669151.52 The sample location designations of Table 3 because of the necessity to relocate a sample are not sequentially inclusive due to the accessibility of an Revision 0 I1I Revision 0 11 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD original sample location.

Sample location 9106-0005-004F was found to be on dry land. Consequently, it was randomly re-located using the VSP software to a new location designated as 9106-0014-043F.

Seven (7) 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. Five (5) of the Seven (7) samples were randomly selected using the Microsoft Excel"RAND" function.

The two (2) samples exhibiting the highest observed radionuclide concentrations by gamma analyses were also selected.The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey," required the collection of five (5) 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 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 forty-two (42) 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.

Seven (7) samples (9106-0014-003F, 9106-0014-01 IF, 9106-014-012F, 9106-0014-018F, 9106-0014-033F, 9106-0007-37F and 9106-0014-038F) were selected for HTD radionuclide analysis by the off-site laboratory.

The implementation of quality control measures included the collection of five (5) split samples at locations (9106-0014-002F, 9106-0014-008F, 9106-0014-018F, 9106-0014-027F and 9106-0014-028F) for comparative analysis by the off-site laboratory.

Revision 0 13 Revision 0 13 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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 forty-two (42) 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 thirty-seven (37) and Co-60 was positively identified in thirty-four (34) of the forty-two (42) samples.Several other radionuclides which were positively identified (i.e., a result greater than two (2) standard deviations uncertainty) could be de-selected or excluded using the 5% and 10% rule described in Section 5.4.7.2 of the LTP.The off-site laboratory also processed a total seven (7) samples for full HTD analysis as required by the sample plan, and for gamma results that indicated additional testing was warranted.

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.Several of the HTD radionuclides met the accepted criteria for detection (i.e., a result greater than two 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.One of the sample results (9106-0014-033F) exceeded the Operational DCGL and required further investigation.

Five (5) of the seven (7) samples were statistical locations that were selected at random. The remaining two (2)samples, were selected for additional testing based on having the highest dose equivalence, based on gamma spectroscopy measurements.

A number of the HTD radionuclides met the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty).

However, each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10% rules.Revision 0 15 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 7. QUALITY CONTROL The five (5) 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. " For all QC split samples, there was an acceptable level of agreement.

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 results was found to exceed the operational DCGL of seventeen (17) mrem/yr, exceeding the investigation level from Table 4. Thus investigations were required to determine compliance with Equation 3 of Section 3.The first step in assessing 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 two (2) meters in each of the (4) four compass directions (north, south, east and west) about the elevated sample point (9106-0014-033F).

When these sample results were reported to be below the investigation levels specified in Table 4, the area was determined to be bounded.The investigation survey was based on original coordinates (those in the Final Status Survey Plan) for the FSS of 9106-0014-033F.

However, when these coordinates were later compared against field logs, it was determined that sampling location was 2.6 meters away from that specified in the sample plan.Consequently, the region was not completely bounded by the samples taken for investigation.

To remedy this situation, samples 9106-0014-026F, 9106-014-027F and 9106-0014-32F were used in conjunction with 9106-0014-033B and 9106-0014-033C to bound the extent of the elevated area. 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 6 provides sample measurement location information (in NAD 1927) and distances from sample location 9106-0014-033F.Revision 0 16 Revision 0 16 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD Table 6 -Investigation Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting Distance from location 9106-0014-033F 236080.09 669070.38 9106-0014-033F (m)9106-0014-033B 236079.67 669077.22 2.09 9106-0014-033C 236074.91 669068.61 1.67 9106-0014-026F 236094.51 669067.28 4.50 9106-0014-027F 236088.10 669082.62 4.46 9106-0014-032F 236073.08 669058.21 4.28 Area (M2) 62.53 Since the bounded area was determined to be 62.5 m 2 , the Area Factor (AF)values from Table 5-5 of the LTP for 75 m2 was conservatively applied to determine the DCGLEMC for each nuclide. With this information, it is possible to assess compliance with the EMC rule.

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 Revision 0 17 Revision 0 17 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 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 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 forty-two (42) 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 4.12 standard deviations, was not unusually large.The difference between the mean and median was 46.3% 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 1.62.The survey area had one elevated measurement location, which was evaluated using the unity EMC test. This resulted in a passing value of 0.324, which is significantly below unity.Revision 0 18 Revision 0 18 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES The anomalies associated with the positioning of investigation samples relative to the area being bounded is discussed in Section 8. This anomaly had no consequences with regards to the conclusion or other findings of this report.13. CONCLUSION Survey Unit 9106-0014 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.An EMC calculation was performed, for the discrete area (62.5 m2 around sample location 9106-0014-033F, in accordance with the LTP equation 5-31 and equation 3 of this report. The results indicated that the area was less than unity. No further action is warranted.

See Tables 6 & 7 of this report for specific information with regard to the EMC calculation.

The dose contribution from sediment in this survey unit is 3.5 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). It has been determined that the dose contribution from groundwater sources is bounded by 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, 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 5.5 mrem/yr Total Effective Dose Equivalent (TEDE).Revision 0 19 DISCHARGE CANAL SURVEY UNIT 9106-0014 RELEASE RECORD 14.

Concentrations are <5X the RL h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.** Indicates analyte is a surrogate compound.^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.Page 108 of 108 Table of Contents G eneral N arrative ...................................................................
