DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9106-0001 (Discharge Canal) is designated as Final Status Survey (FSS) Class 1 survey area and consists of approximately 1,917 m 2 (0.47 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 (FHNP)

(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 Area 9522 is to the north and east (called north as orientated with the north to south flow of the Connecticut River),

Survey Area 9520 is to the north and west, Discharge Canal Survey Unit 9106-0014 is to the south. 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.

This survey unit is bounded by reference coordinates E006 through EO10 and by S072 through S078 (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 "ClassificationBasis Summary" conducted for this survey unit consisted of:

a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "Initial CharacterizationReport" and the "HistoricSite Assessment (HSA) Supplement, "

c) Historic and current survey records review, d) Visual inspections and a "walkdown."

e) Formal or informal interviews with cognizant personnel.

A review of the 10CFR50.75(g)(1) database report identified a number of events that may have impacted this survey unit. This was expected since the discharge canal served as the licensed discharge pathway for liquid releases.

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 Revision 0 3

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD sample analyses indicated that the concentrations of Cs-137, Co-60 and other radionuclides were a small fraction of the Derived Concentration Guideline Limits (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 Historical Site Assessment (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 larger Class 2 survey unit, also designated as 9106-0001. Upon reviewing the FSS data for this area, it was determined that at least one (1) sample exceeded the 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 the Class 1 surveys, a portion of Class 2 Survey Unit 9106-0002 was also included into the southern most area of the two newly designated Class 1 survey units. Survey Unit 9106-0001 encompasses the northern portion of the newly reclassified area and Survey Unit 9106-0014 (new) encompasses the southern portion of the newly reclassified area.

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, at an approved off-site laboratory, by gamma spectroscopy and with radiochemical analyses for Sr-90 and Tritium. Hard-to-Detect analyses were also conducted on one (1) of the fifteen (15) samples. The only plant-related dosimetrically significant radionuclides identified in the samples were Cs-137 and Co-60. All sample analysis results were below the ten (10) mrem/yr design DCGL. Co-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 of 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.

Based upon the results of radiological surveys performed during characterization, it was concluded that there was a significant probability for residual radioactivity to be present in this survey unit in concentrations greater than the Operational DCGL justifying a final survey unit classification of Class 1 (refer to Section 3).

Since the pre-remediation data presented in Table 1 is determined to be sufficient to adequately characterize the survey area, no further characterization efforts were undertaken.

A Class 1 Final Status Survey (FSS) plan was developed and implemented in this survey unit starting in May of 2006.

Prior to completion of the FSS plan, it was determined that a remediation was required to remove sediment material in a region exceeding the associated DCGLEMC. A post-remediation Remedial Action Survey (RAS) was performed under SSWP 06-07-002. This survey confirmed that grab samples of the dredge spoils materials were below the Operational DCGL, indicating that remediation was completed in the affected areas.

The FSS Engineer performed a visual inspection and walk-down during July 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

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, "Preparationof FinalStatus 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 Revision 0 5 Revision 0 5

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD 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 9106-0001 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 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-Hsoii (sediment) + HExisting GW + HFuture GW The total dose under the LTP criteria is twenty-five (25) mrem/yr TEDE from all three (3) components. The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for Connecticut Yankee (CY) is nineteen (19) mrem/yr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the groundwater dose values discussed above.

Revision 0 6 Revision 0 6

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD This survey unit is affected by existing groundwater (reference CY memo ISC 06-024). The dose contribution from existing groundwater is 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/yrTotai= 17 mrem/yrso1l+2 mrem/yrExisting GW+O mrem/yrFuture GW The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.

Note: The survey design used a much smaller value for investigation than the Operational DCGL provided by Table 2 to conservatively account for the contribution to the total dose from existing and future groundwater which had not been established at the time of planning the FSS.

(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 and May of 2004 and final characterization in May of 2006 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 Revision 0 8 Revision 0 8

DISCHARGE CANAL SURVEY UNIT 9106-0001 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 4.0 (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 elevated levels of residual radioactivity are present over portions of the survey unit area, they will be evaluated in conjunction with the average level of residual activity present across the balance of the survey unit to determine whether the total dose associated with the distribution of activity present is in compliance with the release criteria. This is demonstrated in Equation 3.

A separate term will be used in Equation 3 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 ".

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 1 area and discrete, elevated areas of contamination are expected.

A description of the application of the EMC is provided in section 3.0.

Revision 0 10 Revision 0 10

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD 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 0.652 to maintain the relative shift (A/o) in the range of 1 and 3. The resulting relative shift was 2.3. 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 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 fifteen (15) 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 if Environmental Protection (CTDEP), this number needed to be doubled to thirty (30) 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 Locationsfor Final Status Survey. "

VSP 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.

Sample locations 9106-0001-102F, 9106-0001-105F and 9106-0001-1 18F were found to be on dry land. Consequently, they were randomly re-located using the VSP software to three (3)new locations designated as 9106-0001-13 IF through 9106-001-0133F.

The sample plan specified that all sample were to be collected within three (3) meters of the specified coordinates. This is a satisfactory positioning tolerance given the challenges associated with positioning the sampling vessel to fixed locations. In addition, sample procurement was, at times, hindered by rock and other obstructions that limited the penetration of the coring device and in some Revision 0 12 1

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD cases prevented sampling all together. The vendor's positioning logs were reviewed to determine that the positioning was within the specified tolerances.

It was determined that for this survey unit, the maximum sample location offset was found to be 8.51 feet (2.59 meters) at sample point 9106-0001-119.

Three (3) sediment samples were analyzed for the full suite of radionuclides specified in Table 1, exceeding the requirement to analyze 5% of the sample population for HTD analysis specified in procedure RPM 5.1-11. Two (2) of the three (3) samples were randomly selected using the Microsoft Excel "RAND" function. Additionally, the gamma results were screened to ensure that the sample exhibiting the highest observed radionuclide concentration by gamma analysis was selected. This process resulted in selecting an additional sample for HTD 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 two (2) 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. Table 4 provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION Final Status Survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0021. The WP&IR package included a detailed FSSP, job safety analysis, job planning checklist and related procedures for reference. Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The "Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.

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 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 thirty (30) 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". Samples were controlled, transported, stored, and transferred to the off-site laboratory using COC protocols.

Three (3) samples (9106-0001-112F, 9106-0001-121F and 9106-0001-132F) were selected for HTD radionuclide analysis by the off-site laboratory.

The implementation of quality control measures included the collection of two (2) split samples at locations 9106-0001-106F and 9106-0001-117F 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 Revision 0 14 Revision 0 14

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD laboratory analyzed the thirty (30) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy. 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-five (25) and Co-60 was positively identified in twenty-one (21) of the thirty (30) samples. The results reported for the remaining sample analyses indicated that activity was present at levels approaching or below the established detection limits 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.

One (1) of the sample results exceeded the Operational DCGL and required further investigation. A summary of the sample results is provided in Table 5.

For those samples not measured for HTD isotopes, an average calculated value of 5.9% of the DCGL was added to each sample.

Revision 0 16

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD The off-site laboratory also processed a total of three (3) 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 one (1) or more samples; however, each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10% rules, except for C-14. These results are presented in Table 6.

7. QUALITY CONTROL The two (2) 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 In order to expedite the survey design and implementation, unprocessed excess sample aliquot was measured on-site in non-specification geometry (usually a plastic bag). This provided the ability to screen as many sample locations as possible, in advance of receiving the official results from the offsite laboratory, to determine whether any locations may exceed the investigation levels. In turn, this allowed locations to be investigated to assess the extent of suspected elevated areas on a shortened schedule. This process identified two (2) sample results that appeared 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 locations identified for investigation were 9106-0001-112F and 9106-0001-132F. Investigational sample plans were designed and implemented for these locations.

Revision 0 17

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD Upon receiving the official off-site laboratory results it was found that only one (1) (9106-0001-112F) of the two (2) investigated samples exceeded the Operational DCGL. However, investigational sample 9106-0001-132B, intended to bound the extent of contamination about sample 9106-0001-132F, was found to exceed the Operational DCGL. As a result, the EMC test was applied to the elevated region surrounding samples 9106-0001-112F and sample 9106-0001-132B.

The first step in assessing compliance with the EMC unity rule is to determine the extent of the elevated measurement region. In the case of elevated sample location 9106-0001-112F, this was done by taking investigation samples at a distance of approximately two (2) meters in each of the four (4) major compass directions (north, east, south, and west) about the elevated sample point. The actual area for the elevated measurement location was determined by using actual GPS log data and is graphically displayed in Figures 6 & 7 of this report.

2 The extent of the elevated area was approximately 20.2 m2.

For sample 9106-0001-132B, which was found to be in excess of the Operational DCGL after demobilization of the sampling contractor, the extent of the elevated area was bounded by using existing statistical sampling grid points and boundaries. Samples 9106-0001-123F, 9106-0001-124F, 9106-0001-128F and 9106-0001-132F in conjunction with the survey area boundary with Survey Unit 9106-0014 were used to completely bound the elevated area. The actual area for the elevated measurement location was determined by using actual GPS log data and is graphically displayed in Figures 6 & 7 of this report.

2 The extent of the elevated area was approximately 80.4 m2.

Table 7 provides sample measurement location information (in NAD 1927) and distances from sample locations 9106-0001-112F and 9106-0001-132B respectively.

Since the bounded areas were determined to be 20 m 2 and 80 m2 respectively, the Area Factor (AF) values from Table 5-5 of the LTP for 25 m2 and 100 m2 were conservatively applied to determine the DCGLEMC for each nuclide. With this information, it was possible to assess compliance with the EMC rule. This is demonstrated in Table 8.

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD Sample 9106-0001-112A exceeded the Operational DCGL. It would not normally be acceptable to consider samples exceeding the Operational DCGL to be bounding. However, the samples are located essentially on a survey unit boundary, (refer to the maps of attachment 2.) thus, the elevated area extent within the survey unit is bounded. More specifically, in this case, the sample was located adjacent to the concrete pad of the discharge canal outfall structure.

This structure, which was surveyed and released as part of the buried concrete dose model, was observed to have insufficient depths of sediment to permit sampling.

9. REMEDIATION AND RESULTS Prior to designing and implementing this FSS, a Remedial Action Survey (RAS) was performed to determine when the remediation was complete. When an area was believed to be remediated, grab samples were collected from the dredge spoils media and counted on-site using gamma spectroscopy. It was determined that the remediation was completed when dredge materials from the survey unit were below the operational DCGL unitized concentrations.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN No significant changes were made to the Final Status Survey Plan as a result of remediation of a portion of the survey unit.

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 thirty (30) 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 Revision 0 21 Revision 0 21

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD The range of the data, about 4.91 standard deviations, was larger than other survey units in the discharge canal, as would be expected for a Class 1 survey unit. The difference between the mean and median was 26.6% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot shows some positive skewness as confirmed by the calculated skew of 2.62.

The survey area had two (2) elevated measurement locations, which were evaluated using the EMC unity test. This resulted in a less than unity combined passing value of 0.786.

All data, assessments, and graphical representations are provided in Attachment 2.

12. ANOMALIES The anomalies associated with having bounding samples for elevated areas exceeding the operational DCGL are discussed in Section 8. These anomalies had no consequences with regards to the conclusion or other findings of this report.

13. CONCLUSION Survey Unit 9106-0001 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 were required prior to performing the FSS survey presented in this document.

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 1 survey unit.

The dose contribution from sediment in this survey unit is 4.1 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.

Revision 0 22 Revision 0 22

DISCHARGE CANAL SURVEY UNIT 9106-0001 RELEASE RECORD The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity, will not exceed 6.1 mremlyr Total Effective Dose Equivalent (TEDE).

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 cone. by a factor of 4 or more.

- Indicates analyte is a surrogate compound.

A 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.

- 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.

The Qualifiers in this report are defined as follows:

A quality control analyte recovery is outside of specified acceptance criteria

< Result is less than value reported

> Result is greater than value reported A The TIC is a suspected aldol-condensation product B Target analyte was detected in the associated blank 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 H Analytical holding time was exceeded J Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

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 RPD of sample and duplicate evaluated using +/-RL. 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.
