DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD

1. SURVEY UNIT DESCRIPTION Survey Unit 9106-0002 (Discharge Canal) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 5520 m2 ( 1.36 acres) of water covered sediment in an area located approximately 0.20 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: Discharge Canal Survey Unit 9106-0014 is to the north, (called north as orientated with the north to south flow of the Connecticut River), survey unit 9521 is to the east, Discharge Canal Survey Unit 9106-0003 is to the south and Survey Area 9520 is to the west. 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 and it extends up the canal banks to the mean high water level.

This survey unit is bounded by reference coordinates E006 through E010 by S077 through S081 (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 9106-0002 as Class 2 in May 2006.

The "ClassificationBasis Summary" conducted for this survey unit consisted of:

a) A review of the IOCFR50.75 (g) (1) database, b) A review of the "InitialCharacterizationReport" 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 IOCFR50.75(g)(1) database report identified a number of events that may have impacted this survey unit. 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 Revision 0 3

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD 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 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, 0.024pCi/g for Cs-134 and 0.722 pCi/g for Cs-137.

An initial characterization survey of the Discharge Canal was performed during April and May of 2004. However, none of these samples were taken from within the footprint of Survey Unit 9106-0002.

A final characterization was performed by Site Closure personnel in April of 2006 to obtain the necessary data of sufficient data quality for Final Status Survey (FSS) planning purposes. Seven (7) 3-foot core sediment samples were taken from seven (7) locations. All of the samples were analyzed by gamma spectroscopy. Hard-to-Detect analyses were also conducted on one (1) of the seven (7) samples. Sr-90 was found to be a nuclide of concern based on the analysis of the sample. Since a variance cannot be determined from one (1) sample result, the variance associated with the fifteen (15) characterization samples measured for Sr-90 in an adjacent Survey Unit (SU9106-0003) was applied. Although no additional HTD testing was performed for characterization; four (4) of the fifteen (15) samples taken to demonstrate compliance with the release criteria during FSS were tested for the full suite of HTD nuclides to provide additional assurance that all of the radionuclides of concern were appropriately addressed. As a result of characterization, the radionuclides of concern identified for FSS planning purposes were Cs-137, Co-60 and Sr-90 (refer to Table 1).

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 DCGLsjustifying a final survey unit classification of Class 2 (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning is based on the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "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 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 9106-0002 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 9106-0002 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 I shows the mathematical relationship between the three (3) components and the total dose.

Equation 1:

HTotal=Hsoil (sediment) +/- HExisting GW + HFuture GW The total dose under the LTP criteria is twenty-five (25) mrem/yr TEDE from all three (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 existing and future groundwater dose values discussed above.

This survey unit is affected by existing groundwater, but is unaffected by future groundwater (reference CY memo ISC 06-024). Therefore, dose contribution from existing groundwater is two (2) mrem/yr TEDE, based on field data.

This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no concrete foundations or footings remaining within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contributions from future groundwater, the third component is, therefore, zero (0) mrem/yr TEDE.

19 mrem/yriotal= 17 mrem/yrsoil+2 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 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.

The preferred result is the alpha spectroscopy's when both analyses are performed.

Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Characterization was performed in April and May of 2004 as discussed in Section 2. Cesium-137, Cobalt-60 and Strontium-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 8

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, "Preparationof 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 2 of this Release Record.

The DQO process determined that Cs-137, Co-60 and Sr-90 were the radionuclides of concern (refer to Section 3). The sum of fractions or unity rule was used with the individual Operational DCGLs because multiple radionuclides (Cs-137, Co-60 and Sr-90) were considered in the survey design.

Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of nearby adjacent areas and via screening process described in LTP Section 5.4.7.2, "Gross Activity DCGLs". Sr-90 concentrations in sediment and soil were ascertained by direct analysis.

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) did not apply to this survey unit since it is a Class 2 area and discrete, elevated areas of contamination were not expected.

The Sign Test was selected as the non-parametric statistical test to demonstrate that the null hypothesis was rejected. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. In addition, this approach is conservative since it includes background Cs-137 as part of the sample set.

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 Revision 0 9 Revision 0 9

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD accordance with Procedure RPM 5.1-11 to 0.867 to maintain the relative shift (A/a) in the range of I and 3. The resulting relative shift was 2.0. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for. implementation of MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.

This indicates that the survey unit has a high probability of rejecting the null hypothesis, assuming that the characterization data are representative of the FSS results. Survey design specified fifteen (15) sediment core samples for non-parametric statistical testing.

The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey. " Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 2 area.

Subsequent to the initial design, the northern boundary of the survey unit was moved southward. The following are summary explanations of the design considerations and how these affected Survey Unit 9106-0002:

• An adjacent survey unit (SU 9106-0001) was reclassified to a Class I area.

• Since SU 9106-0001 exceeded the 2000 m2 size limit for a Class I area, it was divided into a northern survey unit (SU 9106-0001) and a southern survey unit (SU 9106-0014).

" In order to maximize the area of the two (2) Class I Survey Units, the boundaries of Survey Units 9106-0002 and 9106-0014 were pushed southward.

• Changing the boundaries placed three (3) statistical sample locations (001F, 003F and 006F) and one (1) bias sample location (016F) outside of Survey Unit 9106-0002.

• The affected statistical sample locations were replaced with three (3) randomly generated sample locations (017F, 018F and 019F).

• The biased location was not relocated as it was placed to target an area of interest that was removed from the survey unit as a consequence of the boundary change.

Revision 0 10 Revision 0 10

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD 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.

Two (2) samples were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RAND" function. In addition, two (2) samples, which were determined to contribute the greatest dose based on gamma only analyses, were also selected for HTD analyses. Each sample would be sent off-site for a full suite analysis of the HTD radionuclides specified in Table 2.

The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " included the collection of two (2) 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 LTP requirement of 5%.

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 Revision 0 12

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD locations were accomplished using a GPS interfaced with a navigation and data logging system.

After extraction, water was drained from above the sample by drilling holes above the sediment. The liner was cut, capped, sealed, labeled and turned over to site personnel who processed and controlled the samples under Chain of Custody (COC) protocols in accordance with procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples. " Rinsing of the barrel and associated equipment was performed between sampling events. New aluminum tubes were used for each sample to prevent cross-contamination of subsequent samples.

The fifteen (15) sediment samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Mediafor FinalStatus Survey ". Samples were controlled, transported, stored, and transferred to the off-site laboratory using COC protocols.

Four. (4) samples (9106-0002-004F, 9106-0002-007F, 9106-0003-0011 and 9106-0003-012F) 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 9106-0002-014F and 9106-0002-018F 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 fifteen (15) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy. Sr-90 was analyzed by gas flow proportional counting. All analyses were performed to the required MDC.

Cesium-137 met the acceptance criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty) in thirteen (13), Co-60 met the accepance criteria for detection in fourteen (14) and Sr-90 met the acceptance criteria for detection in two (2) of the fifteen (15) samples.

Several other radionuclides that met the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty) could be de-selected or excluded using the 5% and 10% rule described in Section 5.4.7.2 of the LTP.

The off-site laboratory also processed four (4) samples for full HTD analysis as required by the sample plan. The requested analyses included alpha spectroscopy and liquid scintillation depending upon the radionuclide and the measurement method. All analyses were performed to the required MDC. Four Revision 0 13

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD (4) of the HTD radionuclides met the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty) in more than one sample; however, each of the positive results for HTD radionuclides could be de-selected based on the 5% and 10% rules.

None of the sample results exceeded the Operational DCGL or required further investigation. A summary of the sample results is provided in Table 5.

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. " One (1) split-sample (9106-0002-018F/S) did not meet the comparison criterion for Co-60. A possible cause for this anomaly could be the presence of Co-60 in the form of discrete particles. Such a physical form 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. In this sample, Cs-137 and K-40, a natural radioisotope, were both found to be present at acceptable levels of agreement, therefore, the comparison was determined to be Revision 0 14 Revision 0 14

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD acceptable. For the other QC split samples, there was an acceptable level of agreement between the samples for the radionuclides of concern.

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 Sample investigation levels were not exceeded for this unit, consequently none were performed.

9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN The survey was designed to ten (10) mrem/yr TEDE, which was conservative and necessary at the time of FSS planning. It is no longer required as the total dose from existing and future groundwater has been established. The dose for soil used to demonstrate compliance with the LTP criteria is 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, " for completeness and consistency.

The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The Sign Test shows that the survey unit passes FSS.

Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 2.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation).

Revision 0 15

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD The sample standard deviation was slightly more than the value used for the survey design. This is represented by the shift in the retrospective power curve as shown in Attachment 2g. This would indicate a change to the original LBGR to maintain the number of samples at fifteen (15) to meet the Operational DCGL. However, the value of the LBGR is less of a critical issue as the survey unit has passed the statistical test, and the mean and median values are well below the Operational DCGL when used in conjunction with the unity rule.

Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power. Therefore, the survey unit meets the release criteria with adequate power as required by the DQOs.

The range of the data, about 3.84 standard deviations, was not unusually large.

The difference between the mean and median was 37.5% of the standard deviation which indicates some skewness in the data. The data's 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 1.69.

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

12. ANOMALIES The anomaly associated with the disagreement between the field split number 9106-0002-018F/S has been discussed in Section 7. The source of the disagreement for Co-60, was likely due to Co-60 being present in the form of discrete particles. Such a physical form does not lend itself to homogenous mixing in a sediment matrix. However, comparisons of results for other radionuclides present in the sample were sufficient to demonstrate appropriate implementation of sampling Quality Controls.

13. CONCLUSION Survey Unit 9106-0002 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 2 survey unit.

The dose contribution from sediment in this survey unit is 1.9 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.

Revision 0 16

DISCHARGE CANAL SURVEY UNIT 9106-0002 RELEASE RECORD 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 2.0 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, 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 3.9 mrem/yr Total Effective Dose Equivalent (TEDE).

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.

Re: Missing sample results from GEL (MSR #06-0755)

Dale, It appears that the direction in Jack's original email was misunderstood. Talking this situation over with Cheryl Duffy, it's clear that we took his direction to 'withdraw and exclude samples 1, 3, 6, and 16 from analysis' to be our sample IDs and not the location IDs from the COC. In this case, we should have requested clarification and I apologize that we did not. We have the sample container for 9106-0002-014FS and will relog it today for the requested analyses. Do you need these results expedited?

Also, will you need the narrative for 164220 corrected to reflect the requested cancellation email?

Thanks, Cheryl Dale Randall wrote:

I You are correct. My notes also indicate that due to a design change, we intended to stop analysis for samples 9106-0002-001F, 9106-0002-003F, 9106-0002-006F, 9106-0002-006FS, and 9106-0002-016F. (Before seeing your notes I was a little confused as to why we have a result for 9106-0002-006FS but not 9106-0002-006F) In any case, that leaves the result for sample 9106-0002-014FS as missing. Could this sample result be provided?

Jack, The documentation in the package is incomplete. The COC has a note written on the bottom indicating that the analyses were canceled for several samples at the request of an email received on 6/5/06. The email should have also been included in the package to document the request and this information should have been listed in the Items of I of 3 8 7I/2.51065I PMLOD;U I

Jack:

MSR #06-0755 does not contain results for samples 9106-0002-006F or 9106-0002-014FS. We have documentation indicating that the listed samples were received by GEL, but they were not included with results package (either in hardcopy or electronically). Please query the lab as to their status.

Thanks, Dale P.S. Each of these samples is one half of a split, which would be a problem except that we collected an additional split in the second round of sampling. We thus meet the 5% spilt-sample requirement.

Bottom line: we comply with the FSS requirements, but less justification will be needed if we receive the two sample results that 2 of 3 9 7/25/2006 5:04 PM

• • 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.
