NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9302-0000, is an open land surface soil survey area located in the northwestern portion of the former protected area and outside of the former Radiologically Controlled Area (RCA). Survey Unit 9302-0000 is designated as Final Status Survey (FSS) Class 3 and consists of approximately three thousand four hundred and ninety (3,490) square meters of open land and is located approximately one thousand one hundred and twenty-five (1,125) feet from the reference coordinate system benchmark used at Haddam Neck Plant (HINP) (see Attachment 1). The site benchmark is based on the Connecticut State Plan System North American Datum (NAD) 1927 (Northing 237370.20, Easting 667394.51). The topography is fairly level throughout Survey Area 9302 with a slight slope from east to west, toward the Connecticut River. This survey unit is bounded on the north (plant north is oriented by the general north to south flow of the Connecticut River) by Survey Unit 9514-0000, a Class 3 survey unit, on the east by Survey Unit 9313-0000, a Class 2 survey unit, on the south by 9306-0000 and 9304-0001, both Class 2 survey units and on the west by 9512-0000, a Class 3 survey unit.

The reference coordinates associated with this survey unit are E002 through E006 by S062 through S067 (refer to "HNP License Termination Plan" (LTP) 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 "Classification Basis Summary" conducted for Survey Unit 9302-0000 consisted of:

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

c) Historic and current survey records review, d) Visual inspections and a "walk-down."

The Historical Site Assessment (HSA) and Supplement, as well as, other historical documents (e.g., the IOCFR50.75(g)(1) files) identify a number of events that may have impacted this survey area.

a. ACR# 97-1055-Floor monitor identified three (3) small radioactive spots embedded in the asphalt north of the Turbine Building roll-up doors, east of GS-1 and inside the Turbine Building.

Revision 0 3

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD

b. CR# 98-0992-During a clean-up outside the Radiological Control Area (RCA), sand was inadvertently scooped up and placed in a dumpster.

Follow-up analysis indicated that the sand contained low levels of radioactive material above the environmental release levels.

c. CR# 02-0037-A mop head containing licensed radioactive material was found in the industrial area trash.

d. CR# 03-0450-Fixed contamination (3,400 ccpm) was found in the asphalt outside the North RCA gate.

e. CR# 03-0562-Radioactive material was found at GS-1.

f. CR# 05-0509-Several Barrels were identified during excavation of the southwest portion of the former Service Building.

g. CR# 05-0579-Spill at Chemistry trailer.

h. CR# 05-0736-The north waste storage tent area was leaking through the north berm.

The radiological assessments and characterization surveys in this area to support decommissioning activities commenced in 2004 and continued through 2006 as work progressed. Sampling was performed in the footprints of the PBX Utilities and Commodities Tent or the location of the Former ADMREC Buildings (numbers 201, 134 & 180). Soil samples were analyzed at the on-site laboratory by Gamma Spectroscopic Analysis. A total of fourteen (14) demolition support or characterization samples were identified from this survey area. All of these samples were utilized to determine both the radionuclide(s) of concern and the standard deviation of the sample population for FSS plan development.

Cs-137 and Co-60 were positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in eight (8) of the fourteen (14) samples in concentrations up to 0.6% of the Operational Derived Concentration Guideline Level (DCGL) when incorporating the "sum of fractions". Therefore, both Cs-137 and Co-60 are both identified as radionuclides of concern for FSS. Based on the lack of evidence in the HSA and the sample results from adjacent survey areas, HTD radionuclides were de-selected as radionuclides of concern for this FSS plan. A summary of the demolition support and surface characterization sample results are provided in Table 1.

Revision 0 4

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD Parameter Cs-137 Co-60 Operational Soil Derived Concentration Guideline Level (DCGL) (pCi/g): 4.75E+00 2.29E+00 Minimum Value: -2.28E-03 -1.05E-02 Maximum Value: 9.1 1E-02 9.38E-02 Mean: 1.55E-02 8.64E-03 Median: 1.86E-03 -4.20E-04 Standard Deviation: 5.16E-02 5.24E-02 The FSS Engineer performed a visual inspection and walk-down on October 31, 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

This survey area is affected by existing and future groundwater (reference CY memo ISC 06-024) which will be a source of dose from residual radioactivity, as discussed in Section 3 under the Data Quality Objectives.

Based upon a review of the historical information and the results of the Characterization Survey data, it was concluded that there was a low probability for residual radioactivity at levels approaching a small fraction of the DCGLs, justifying a final survey unit classification of Class 3 (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-11, "Preparationof 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 incorporated 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 indicate that residual activity within the survey unit does not exceed the release criteria. Therefore, the survey unit would satisfy the primary objective of the FSS plan.

Revision 0 5

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9302-0000 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 average levels of radioactivity above background levels and are 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), existing groundwater radioactivity and future groundwater radioactivity that will be contributed by building basements and footings.

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 I H Total HSoil + HExistingGW + HFutureGW 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 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.

CY memo ISC 06-024 addresses the impact of existing and future groundwater on specific survey areas at CY. CY memo ISC 06-024 states that Survey Area 9302 is affected by existing groundwater and is also considered impacted by future groundwater radioactive contamination, as there are concrete foundations or footings remaining within the groundwater saturated zone in the area.

Therefore, the dose contribution from existing groundwater in Survey Unit 9302-0000 is bounded by two (2) mrem/yr TEDE and the dose contribution from future groundwater, the third dose component, is also two (2) mrem/yr TEDE.

Equation 2 19 mrem/yrotaIl = 15 mremnyrsil + 2 mremlyrExisting Gw+ 2 mrem/yrFutureGw The allowable dose for soil in this survey unit is fifteen (15) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity Revision 0 6

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD resulting in fifteen (15) mrem/yr TEDE is designated as the Operational DCGL (DCGLop), and has been established for the radionuclides of concern as provided in Table 2.

However, the preferred result is the alpha spectroscopy when both analyses are performed.

Revision 0 7 Revision 0 7

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

As stated previously, Cs-137 and Co-60 were positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in eight (8) of the fourteen (14) samples at concentrations up to 0.6% of the Operational DCGL when incorporating the "sum of fractions". Therefore, both Cs-137 and Co-60 were identified as radionuclides of concern for FSS. Based on the lack of dvidence in the HSA and the sample results from adjacent survey areas, HTD radionuclides were de-selected as radionuclides of concern for this FSS plan. A summary of the post remediation and characterization sample results are provided in Table 1.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparationof Final Status Survey Plans".

The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The DQO process determined that both Cs-137 and Co-60 would be the radionuclides of concern in Survey Unit 9302-0000 (refer to Section 3). The characterization survey did not identify any HTD radionuclides of concern for this survey unit. Subsequently, surrogate DCGLs were not required for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs".

Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performance of this FSS would be evaluated to ensure adequate survey design. Radionuclide screening or de-selection is a process where the dose contribution from an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 3 area and discrete, elevated areas of contamination were not expected.

Revision 0 8 Revision 0 8

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. This approach was conservative since it included background Cs-137 as part of the sample set.

The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.98 to maintain the relative shift (A/a) in the range of 1 and 3. The resulting relative shift was 2.00. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10CFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing. Additionally, three (3) judgmental or biased surface soil samples were collected within this survey unit. Two (2) of the judgmental samples were located in the vicinity of the east end of the survey unit (closest to the Radiological Control Area) and one (1) additional judgmental sample was located in the vicinity of GS- 1. The general locations of the judgmental samples are illustrated in Attachment 1 and the coordinates are provided in Table 3.

The locations of the fifteen (15) soil samples used for non-parametric testing were determined randomly using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Random sampling locations were selected for this survey unit, which is appropriate for a Class 3 area. Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy.

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 numerical designations are provided along with the GPS coordinates in Table 3.

Revision 0 10

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis. Two (2) soil samples, or about 10% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RANDBETWEEN" function. Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided 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. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function.

Table 5-9 of the LTP states that the scanning coverage requirements for an outdoor Class 3 area are judgmental. The fraction of scanning coverage was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS. Based on the historical site assessment, the characterization data available, and the use of this survey unit, it was determined that scanning was necessary to be performed in two (2) separate areas. The total surface area to be scanned was approximately 10% of the survey unit. A map of the scan grid locations is provided in Attachment 1.

For this Class 3 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8. Table 4 provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Final Status Survey Plan 9302-0000. The FSS plan included a 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.

Two (2) scan areas were established that constituted approximately 10% of the surface area of Survey Unit 9302-0000. Grid lines, one (1) meter wide, were painted on the ground of the scan area. A background survey was performed around the survey unit and it was determined that, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 6,510 counts per minute (cpm) up to 9,330 cpm.

Revision 0 12

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD The scan areas were established and scanned for elevated readings (see Attachment 2 for all scan results). Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with audio response. The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. Approximately 10% of the survey unit was scanned.

Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification. At each sample location, a one (1) meter radius around the sample flag or paint mark was scanned for elevated radiation levels.

Fifteen (15) surface soil 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 Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples."

Three (3) judgmental or biased surface soil samples (9302-0000-016B, 9302-0000-017B and 9302-0000-018F) were identified and collected within this survey unit.

Two (2) samples (9302-0000-001F and 9302-0000-014F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of two (2) samples (9302-0000-013F and 9302-0000-015F) for "split sample" analysis.

6. SURVEY RESULTS All field survey activities were conducted between March 29, 2007 and April 3, 2007.

The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan results for sample measurement locations. Scan results for the entire survey unit are provided in Attachment 2.

The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels approaching the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 7.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC.

No HTD radionuclides were positively identified (i.e., a result greater than two (2) standard deviations uncertainty). In accordance with LTP Section 5.4.7.2, "Gross Activity DCGLs", the criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. Two (2) sample locations were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey". There was acceptable agreement between the field split results at locations 9302-0000-013F and 9302-0000-015F.

The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachment 4 for data and data quality analysis results.

8. INVESTIGATIONS AND RESULTS One (1) investigative sample was collected from scan area 1 at a location that exhibited an elevated scan reading. The investigative sample results are shown in Table 9 below.

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 No changes were made to the FSS plan for this survey unit.

11. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "DataQualityAssessment, " 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 evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, 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 3.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). The mean and median values are well below the Operational DCGL. 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 criteria with adequate power as required by the DQOs. The basic statistical quantities for the statistical sample population are provided below in Table 10.

DCGLop: 4.75E+00 2.29E+00 Minimum Value: -5.37E-03 -3.63E-02 Maximum Value: 2.15E-01 1.1OE-01 Mean: 2.74E-02 8.26E-03 Median: 1.09E-02 5.63E-03 Standard Deviation: 5.67E-02 3.20E-02 For Cs-137, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected. The difference between the mean and median was about 29% 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 indicates positive skewness as confirmed by the calculated skew of 3.15 for Cs-137.

Revision 0 20

NORTHWEST PROTECTED AREA GROUNDS SURVEY UNIT 9302-0000 RELEASE RECORD Co-60, although included in the FSS plan for compliance purposes, was positively identified in only one (1) of the fifteen (15) samples collected for non-parametric statistical testing. Assessment of the basic statistical quantities and graphical representation of Co-60 was not considered useful given the limited number of statistically significant data points to represent the distribution.

All data, assessments, and graphical representations are provided in Attachment 4.

12. ANOMALIES No anomalies were noted.

13. CONCLUSION Survey Unit 9302-0000 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison and remediation was not required.

All identified radionuclides of concern were used for statistical testing to determine the adequacy of the survey unit for FSS.

The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit is properly designated as Class 3.

The dose contribution from soil is 0.196 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations and footings containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024); therefore, the dose contribution from future groundwater is two (2) 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 4.196 mrem/yr TEDE. Therefore, Survey Unit 9302-0000 is acceptable for unrestricted release.

Data Review Qualifier Definitions Page 10 of 85

Data Review Qualifier Definitions Qualifier Explanation

• A quality control analyte recovery is outside of specified acceptance criteria

• • Analyte is a surrogate compound

• Result is less than value reported

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

The Qualifiers in this report are defined as follows:

• • Analyte is a surrogate compound

< Result is less than value reported

> Result is greater than value reported A The TIC is a suspected aldol-condensation product B For General Chemistry and Organic analysis the 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 ND Analyte concentration is not detected above the detection limit 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 QC Samples were not spiked with this compound Page 84 of 85

A 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.

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.

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.

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.
