EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD

1. SURVEY UNIT DESCRIPTION Survey Unit 9527-0004 (East Mountain Side) is designated as Final Status Survey (FSS) Class 2 and consists of 3,500 m2 (0.86 acres) of uninhabited open land located approximately 0.10 miles from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1, Figure 1).

The survey unit is bounded by a Class 3 survey unit, 9526-0000 to the north (called north as oriented with the north to south flow of the Connecticut River),

a running trail to the east, a fence to the south, and a stone wall to the west. The survey unit comprises wooded terrain with some steep rock ledge and rock outcroppings within the interior. A stream runs through the interior of the survey unit.

The soil of this survey unit meets the requirements for unrestricted release as a Class 2 survey unit under the criteria and requirements of the HNP License Termination Plan (LTP).

The reference coordinates associated with this survey unit are E015 through E025 by S045 through S062 (refer to 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).

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 9527-0004 as Class 2 in August 2005.

The Classification Basis Summary conducted for Survey Unit 9527-0004 consisted of:

a) A review of the 10CFR50.75 (g) (1) database, b) A review of the Initial Characterization Report and the Historic Site Assessment (HSA) Supplement, c) Historic and current survey records review, d) Visual inspections and a walkdown.

A review of the 10CFR50.75 (g) (1) database report identifies six (6) documents associated with or relating to this survey unit.

a) Event PIR 80-37: Contamination was documented to be present in an area outside the restricted area. Small areas of low-level contamination were found on the facility grounds through routine survey in a normally non-radioactive area. The areas were cleaned up in 1980.

Revision 1 3

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD b) Radiological Assessment Branch (RAB) memo NE-83-RA-1374 (September 1983): Results of a contamination survey outside the southeast RCA boundary has identified plant related activity in an adjacent survey unit to 9527. According to the memo the source could have been the events described by PIR 80-37.

c) Adverse Condition Report ACR 97-0994: Soil sample analysis identified plant related radioactivity on hillside east of plant (in another survey unit of 9527).

d) Scoping Survey Report 1998: Results of scoping samples performed for decommissioning characterization data. Cesium-137 was the predominate radionuclide found in this survey unit during the scoping survey. No other plant-related radionuclides were identified in this survey unit.

e) Event CR 05-0244: Tank farm material with low-level fixed contamination was found on the East Mountain Side in another survey unit of 9527. The single piece of tent material was found in survey unit 9527-0005 along the fence and about five hundred fifty (550) feet from the nearest boundary of 9527-0004.

f) Memo ISC 05-045: Periodic surveillance following final status survey.

Surveillance is required periodically by the LTP to ensure the radiological condition does not significantly change from the FSS results. The memo documents no negative change in the radiological status.

A review of the Initial and Supplemental Characterization Reports as well as the previous Classification Basis Summaries provided no additional information pertinent to classification.

Characterization was performed by Site Closure personnel in April 2005 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). The reported concentrations of Cs-137 found in the soil were statistically consistent with those concentrations in wooded areas determined from off-site locations as documented by Health Physics Technical Support Document (TSD) BCY-HP-0063, Background Cs-137 Concentration in Soil. The average concentration was 0.695 pCi/g as expected; however, one (1) sample reported Cs-137 at a concentration of 2.37 pCi/g. The same sample reported Co-60 at a concentration of 0.0954 pCi/g. The basic statistical quantities (i.e., mean, standard deviation, median) for Cs-137 and Co-60 are provided in Table 1.

The final designation was Class 2 based on historical information (HSA Supplement and LTP Table 2.10 and 2.11B) and characterization survey data which resulted in the expectation that no FSS sample would be reported in a concentration that that would exceed the LTP criteria.

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, Preparation of Final Status Survey Plan, and the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). A summary of the main features of the DQO process are provided herein.

The DQO process 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 satisfy the release criteria objective of the FSS. Probabilistic sampling is a preferred method to select a sample so that each item in the population being studied has a known likelihood of being included in the sample. Probabilistic sampling might include simple random sampling where every sample has the same chance of being included, or systematic random sampling where samples are arranged in some order and a random starting point is selected.

The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9527-0004 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).

Revision 1 5

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of Derived Concentration Guideline Values (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 from 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 1 shows the mathematical relationship between the three (3) components and the total dose.

Equation 1:

HTotal=HSoil + HExisting GW + HFuture GW The total dose under the LTP criteria is 25 mrem/yr TEDE from all three components. The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for Connecticut Yankee (CY) is 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 (reference CY memo ISC 06-024 and the Final Status Survey Final Report Phase III). The dose contribution from existing groundwater is bounded at 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 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.

Equation 2:

19 mrem/yrTotal=17 mrem/yrSoil+2 mrem/yrExisting GW+0 mrem/yrFuture GW The allowable dose for soil in this survey unit is 17 mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in 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 Revision 1 6

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD 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 spectroscopys 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 2005 as discussed in Section 2. Cesium-137 was found to be the predominate radionuclide of concern. Cobalt-60 was included in the survey design based on the characterization survey results. The basic statistical Revision 1 7

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD quantities (i.e., mean, standard deviation, median) for Cs-137 and Co-60 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.

Laboratory DQOs and analysis results were to be reported as actual calculated results. Results reported as less than Minimum Detectable Concentration

(<MDC) would not be accepted for FSS. Sample report summaries were to include unique sample identification, analytical method, radionuclide, result, and uncertainty of two 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. To assist the FSS Engineers when preparing survey plans for FSS, guidance is provided in Procedure RPM 5.1-11, Preparation of Final Status Survey Plans. By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP. The FSSP uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

Characterization was performed by Site Closure personnel in April 2005 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern (refer to Section 3). The sum of fractions or unity rule would be used with the individual Operational DCGLs because multiple radionuclides (Cs-137 and Co-60) were considered in the survey design. Other radionuclides identified during FSS would be evaluated to ensure adequate survey design and compliance with the unity rule.

Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of nearby adjacent areas and via screening under 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 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 the survey unit is a Class 2 and discrete, elevated areas of contamination were not expected.

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, Revision 1 8

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD 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 0.5 to maintain the relative shift

) in the range of 1 and 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 the 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. Survey design specified fifteen (15) surface soil 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.

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.

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD A minimum of two (2) judgmental or biased samples were to be collected at locations selected by FSS Supervision based on professional judgment and observation during characterization and walkdowns to determine areas having the potential for residual radioactivity (e.g., runoff and collection, area disturbance). The number of judgmental samples represented 10% percent of the number of samples that would be used for non-parametric statistical testing.

Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for HTD analysis, three (3) soil samples or 20% 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 would be 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 survey specific 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 RANDBETWEEN function. The number of quality control soil samples was determined to be 10% of the samples used for non-parametric statistical testing.

The LTP specifies that scanning will be performed in a combination of systematic and judgmental measurements for a Class 2 land area and cover 10%

to 100% of the area. 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. Approximately 25% of the survey unit was to be scanned based on the characterization survey and sampling results.

For this Class 2 survey unit, the Investigation Level for soil sample measurement results and area scanning are those levels specified in LTP, Table 5-8, Investigation Levels. 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. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2005-0054. 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.

Survey activities occurred August 10 through August 17, 2005.

The scan areas were marked out and scanned for elevated readings (see Attachment 2 for Scan Area Results). Scanning was performed with an Revision 1 11

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD 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 26% of the survey unit was scanned.

Using GPS coordinates, sample measurement locations were identified and marked with a surveyors flag for identification. At each sample measurement location, a one (1) meter radius around the sample flag 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) samples (9527-0004-004F, 9527-0004-009F and 9527-0004-012F) were randomly selected for HTD radionuclide analysis by the off-site laboratory.

Two (2) biased soil samples (9527-0004-016F and 9527-0004-017F) were collected and analyzed by the off-site laboratory for gamma spectroscopy.

The implementation of survey specific quality control measures included the collection of two (2) samples (9527-0004-002F and 9527-0004-013F) for split sample analysis by the off-site laboratory.

6. SURVEY RESULTS The seventeen (17) sample measurement locations identified in the FSS plan were scanned about a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan area survey. Scan area results are provided in Attachment 2.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC, Charleston, South Carolina. The laboratory analyzed the fifteen (15) samples taken for non-parametric statistical testing, the associated duplicates, and the biased samples using gamma spectroscopy. Gamma spectroscopy analysis was performed to the required Revision 1 14

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD MDC. Gamma spectroscopy results identified radionuclides other than Cs-137 and Co-60 meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty). All could be de-selected or excluded using the 5% and 10% rule described in Section 4.

Cesium-137 was identified in all of the fifteen (15) samples. Cobalt-60 was identified in two (2) of the fifteen (15) samples. The average gamma spectroscopy results for Cs-137 were slightly higher than 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.

None of the samples exceeded 61% of the Operational DCGL. Two (2) reported sample results exceeded the soil investigation criteria based on achieving 8 mrem/yr TEDE. Investigation was conducted in accordance with the FSSP (refer to Section 8). A summary of the sample gamma spectroscopy results is provided in Table 7.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. Ten percent (10%) of the samples 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 unacceptable agreement between field split results for Cs-137 which was identified under Condition Report (CR) 05-0781.

Evaluation of the data using the reported results for NORM resulted in acceptable agreement. The source of the disagreement for Cs-137 is likely a disproportionate amount of organic material in the field splits. A review of the Daily Survey Journals (field notes) and interviews with FSS Supervision indicate this to be the apparent cause. Field Supervision noted that the rocky terrain and undergrowth made sample collection difficult (refer to Section 8 for additional discussion on this topic).

The sample analysis vendor, General Engineering Laboratories, LLC, Charleston, South Carolina, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachment 2 for data and data quality analysis results.

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD

8. INVESTIGATIONS AND RESULTS Fourteen (14) localized areas were found to verifiably exceed their investigation level during the scan area survey. The Daily Survey Journals described the areas as abounding with rock outcroppings covered by a thin layer (about 1 inch to 2 inch) of dead roots and dead vegetation (refer to picture 1).

Picture 1 - A view showing the topography of the survey unit looking north-northeast.

The suspected source of the high background is NORM given the survey units geology. The rock types found on the hill and under the station area consist of a suite of recrystallized volcanic rocks mapped regionally as the Monson Gneiss and Middletown Formation (refer to the HNP Historical Site Assessment Supplement). Rock outcroppings and ledges containing microcline-quartz pegmatite, a coarse grained rock of granitic composition, have been identified on HNP property (refer to Health Physics TSD CY-HP-0150, Investigation of Rock Outcropping Exhibiting Elevated Activity.) Uranium is included with the minerals associated with this pegmatite. A primary component of pegmatite intrusives is the mineral orthoclase which contains K-40. Although the concentrations of K-40 are relatively small compared to the other isotopes, it is enough to be detected during a survey considering the fact that the pegmatites are extensively injected into the bedrock.

Evaluation of the soil sample data shows that two (2) sample results were higher than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP and the survey design specification for investigation (see Note in Table 4). The sample locations were 9527-0004-0002 and 9527-0004-Revision 1 17

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD 0003 (the results can be found in Table 7). Confirmatory samples were collected to determine the cause and extent of contamination. The samples were analyzed by the off-site laboratory and the reported results confirmed elevated radioactivity. Additional samples were collected at sample location 9527-0004-003 and were analyzed by gamma spectroscopy on-site. Additional samples could not be collected at sample location 9527-0004-002 due to the amount of bedrock outcropping and lack of soil to collect according to the Daily Survey Journal. The on-site and off-site gamma spectroscopy results are included in Table 10.

However, subtracting background from past atmospheric nuclear weapons testing yields a net Cs-137 concentration below the Operational DCGL. The concentration of Cs-137 found in off-site wooded locations was 0.819 pCi/g +/- 0.460 as documented by Health Physics Technical Support Document (TSD) BCY-HP-0063, Background Cs-137 Concentration in Soil.

The corresponding net result for confirmatory sample 9527-0004-002C is 4.71 pCi/g, a fraction of the Operational DCGL equal to 0.876. Secondly, what has been identified is a topical and likely artificially biased, increase of Cs-137 due to natural conditions and mechanisms based on the following explanation.

The likely source of the high activity in the confirmatory sample is accumulation and concentration of Cs-137 in the sample media. The media in Revision 1 18

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD this case was not soil taken to a depth of 6 inches, the minimum equal depth of soil mixing used in Cy LTP conceptual model for the Resident Farmer scenario, but organic detritus and humus from decaying plant and tree material clumped in a thin, dense layer over rock. The layer of material available for sampling, 1 inch to 2 inches, would have required collecting the media horizontally as opposed to vertically to obtain sufficient sample material. This would tend to bias the Cs-137 activity high due to the increase of surficial activity (pCi/m2) across the area of collection.

Furthermore, sample location 9527-0004-002 is within an area that receives considerable runoff from the mountainside. Pooling has been observed in the area from runoff and from a nearby stream which swells into the area following heavy rainfall and during spring thaws. The area also contains a dense root system as discussed previously. The MARSSIM recognizes that vegetative cover and foreign material (e.g., plant roots) are generally not considered part of the sample and should be removed. Picture 2 clearly shows a dense root system within the layer of material available for sampling which would be difficult to remove in the field using available equipment and techniques. Cumulative bioaccumulation of deposited radionuclides from the soil to the plant roots would be another likely source of higher than expected radioactivity, especially given the down gradient location and the favorable conditions for runoff and pooling.

Revision 1 19

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD Additional scanning was performed in two (2) small locations in February 2006 to obtain additional data relevant to the DQOs. The scanning was performed in two (2) sections of approximately nine hundred square feet (900 ft2). The Daily Survey Journals report that exposed bedrock comprises 70% to 85% of the scan area. Two (2) elevated areas were identified and the source was determined to be exposed bedrock.

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

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN The survey was designed to 8 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 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 passed 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).

The sample standard deviation was slightly more than the value used for the survey design. This would indicate a change to the original LBGR to maintain the number of samples at fifteen to meet the Operational DCGL. However, the value of 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.

Revision 1 20

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD The range of the data, about 3.3 standard deviations, was not unusually large.

The difference between the mean and median was 27% of the standard deviation. The difference is enough to indicate skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot shows significant positive skewness as confirmed by the calculated skew of 1.5 and probably due to the differences in terrain and the collection of runoff activity in low-lying areas.

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

12. ANOMALIES The anomalies associate with the disagreement between the field splits has been discussed in Section 7. The source of the disagreement for Cs-137, especially at sample location 9527-0004-0002, was likely a disproportionate amount of organic material between the field splits.

Evaluation of the data showed that one of the investigation sample results exceeded the Operational DCGL in conjunction with the unity rule. Subsequent explanation of the elevated results for Cs-137 was discussed in Section 8. The likely source of the high activity in the samples was accumulation and concentration of Cs-137 due to natural conditions and mechanisms in samples comprised of organic detritus and humus.

No other anomalies were noted.

13. CONCLUSION Survey Unit 9527-0004 has met the final DQOs of the FSS. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison and remediation were not required.

The sample data passed the Sign Test. The null hypothesis was rejected.

Graphical representation of data indicates significant positive skewness as that is probably due to the differences in terrain and the collection of runoff. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. One confirmatory sample, 9527-0004-002C, was above the Operational DCGL; however, this has been identified as a topical and likely artificially biased increase of Cs-137 due to natural conditions and mechanisms.

The survey unit is properly designated as Class 2.

The dose contribution from soil is less than 4 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 and the Final Status Survey Final Report Phase III). Therefore, the dose contribution from existing groundwater is bounded by 2 mrem/yr TEDE.

Revision 1 21

EAST MOUNTAIN SIDE SURVEY UNIT 9527-0004 RELEASE RECORD 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 and the Final Status Survey Final Report Phase III). The dose contribution from future groundwater, the third dose component, is therefore 0 mrem/yr TEDE.

• • 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.
