SURVEY UNIT DESCRIPTION Survey Unit 9527-0002 (East Mountain Side) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 9,740 m 2 (2.41 acres) of wooded area located approximately 0.13 miles from the reference coordinate system benchmark used at the Haddam Neck Plant (HNP) (see Attachment 1, Figure 1). The survey unit is bounded by a fence on the eastern and western sides, an unpaved road along the western side and a stone wall along the northern side. A Class 3 survey unit, 9527-0003, bounds this survey unit on the south. The survey unit comprises wooded terrain with some steep rock ledge and rock outcroppings within the interior.The reference coordinates associated with this survey unit are E016 through E025 by S062 through S070 (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).A review of the historical files indicates two (2) events potentially impacting this survey unit. Contamination was found in 1980 in uncontrolled areas including the East Mountain Side (refer to Plant Information Report PIR 80-37).Recently, tank farm tent material with low-level fixed contamination was found on the East Mountain Side (refer to Condition Report CR 05-0244). This material was found in another survey unit of 9527. Walkdowns of the remaining East Mountain Side did not identify more tent material. The single piece of tent material was found in Survey Unit 9527-0005 along the fence and adjacent to the western boundary of Survey Unit 9527-0002. In Section 5.4.7.1 of the LTP, Equation 5-1 expresses the total dose contribution from three (3) components; soil contribution, existing groundwater contribution and future groundwater contribution. The survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-1. This survey unit is considered impacted by existing groundwater radioactive contamination as the survey unit is within the capture zone perimeter for an affected monitoring well. The dose contribution from the existing groundwater contamination will be addressed later and will be included to show compliance with site unrestricted release criteria as required by the LTP. This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area. The dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.Revision 0 3 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 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 9527-0002 as Class 2 in August 2005.The "Classification Basis Summary" conducted for this survey unit consisted of: a) A review of the IOCFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walkdown." A review of the 1OCFR50.75 (g) (1) database report identifies six (6) documents associated with or relating to this survey area.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.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 area 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. A single piece of tent material was found in Survey Unit 9527-0005 along the fence and adjacent to Survey Unit 9527-0002. 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 Revision 0 4 -EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 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. A survey plan was initiated and executed by Site Closure personnel in April 2005 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). No areas of elevated radioactivity were identified in the survey unit.Seventeen (17) soil samples were collected and analyzed using gamma spectroscopy. The concentrations of Cs-137 found in the soil were slightly lower than 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 values for Cs-137 and Co-60 are provided in Table 1.Table I -Basic Statistical Quantities for Cesium-137 from the._ Characterization Survey Parameter Cs-137 (pCL/g) CO-60 (PCIIR)Minimum Value: 1.78E-01 -1.23E-02 Maximum Value: 1.04E+00 5.399E-02 Mean: 5.34E-01 1.64E-02 Median: 5.52E-01 1.32E-02 Standard Deviation: 2.42E-01 2.02E-02 The FSS Engineer performed a visual inspection and walkdown during August 2005 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions. Assessment of the groundwater impact is discussed in Section I and Section 13.The classification basis shows that the expected residual radioactivity in the survey unit would be below the site remediation criteria and are consistent with procedural guidance, thereby sufficient to justify the final designation as Class 2.3. DATA QUALITY OBJECTIVES (DQO)FSS design and planning is based on the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5.1-1 1, "Preparation of Final Status Survey Plan, " and the "Multi-Algency 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 Revision 0 5 Revision 0 5 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD an alternate condition. The baseline condition is technically known as the null hypothesis. Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection. In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria. Rejection of the null hypothesis would satisfy the release criteria objective of the FSS. 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 this survey unit 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 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 additional future groundwater radioactivity from building basements and footings.A reduction to the Base Case Soil DCGLs provided in Chapter 6 of the LTP must be performed to ensure compliance with the release criteria of twenty-five millirem (25 mrem) in a year Total Effective Dose Equivalent (TEDE) when all three pathways (soil, existing groundwater and future groundwater) are potentially present. Chapter 5 of the LTP shows a compliance formula, Equation 5-1, for including the total dose from the three media. The reduced DCGL is called the Operational DCGL whose relationship to the Base Case Soil DCGL is shown by Equation 5-3 of the LTP. The Base Case Soil DCGL for Cs-1 37 and the DCGLs for all the other radionuclides potentially present in soil were administratively reduced by about 70% to ensure compliance with the 25 mrem in a year TEDE criterion (Table 2).Revision 0 6 Revision 0 6 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD Table 2- Radionuclide Specific Base Case Soil DCGL, Operational DCGLs and Required Minimum Detectable Concentrations Radionuclide Base Case Soil Operational DCGL Required MDC DCGL pCi/g)(1) (pCi/g) (2) (pCl/g)(') H-3 4.12E+02 1.32E+02 1.65E+O1 C-14 5.66E+00 1.81E+00 2.26E-01 Mn-54 1.74E+01 5.57E+00 6.96E-01 Fe-55 2.74E+04 8.77E+03 I.

Seventeen (17) soils samples were collected and analyzed during characterization as discussed in Section 2. The samples were collected through biased sampling. Cesium-137 was found to be the predominate radionuclide of concern in soil. Cobalt-60 was included in the survey design based on the 1997 scoping survey results. The mean and variability of Cs-137 and Co-60 in soil in this survey unit was determined during characterization. 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 to be performed before issue and after the instrument had been used. Control and accountability of survey instruments was to be maintained to assure the quality and prevent the loss of data.Revision 0 7 Revision 0 7 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 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.Seventeen (17) data points from characterization were used to determine concentration variability. The samples were collected through biased sampling over a simple grid design. The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern for soil in this survey unit (refer to Section 3). The sum of fractions or unity rule will be used with the individual Operational DCGLs because multiple radionuclides (Cs-137 and Co-60) are considered in the survey design. Other radionuclides identified during FSS would be evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit based low potential for HTD radionuclides and via screening under LTP Section 5.4.7.2. 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 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, 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 Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.81 to maintain the relative shift (A/a) in the range of I 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 Revision 0 8 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 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.Table 3 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9527-0002-001 F 237214.49 668896.74 9527-0002-002F 237135.71 668851.26 9527-0002-003F 237135.71 668942.22 9527-0002-004F 237135.71 669033.18 9527-0002-005F 237056.94 668805.78 9527-0002-006F 237056.94 668896.74 9527-0002-007F 237056.94 668987.70 9527-0002-008F 236978.16 668760.30 9527-0002-009F 236978.16 668851.26 9527-0002-OlOF 236978.16 668942.22 9527-0002-01 IF 236978.16 669033.18 9527-0002-012F 236899.39 668805.78 9527-0002-013F 236899.39 668896.74 9527-0002-014F 236899.39 668987.70 9527-0002-01SF 236820.61 668942.22 There were to be two (2) judgmental samples total for soil sampling. The soil sample locations would be determined 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 about 13%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, at least three (3) soil samples or 20% of the number of samples that would be used for non-parametric statistical testing were Revision 0 9 Revision 0 9 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 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." 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 13% of fifteen (15) samples, rounded up to the next whole number.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 area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8,"Investigation Levels."

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 23, 2005 through September 22, 2005.The scan areas were marked out and scanned for elevated readings (see Attachment 2 for Scan Area 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.Using GPS coordinates, sample measurement locations were identified and marked with a surveyor's 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, "Collecfion 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 Custodyfor Final Status Survey Samples." Three (3) soil samples (9527-0002-004F, 9527-0002-009F and 9527-0002-012F) were randomly selected for HTD radionuclide analysis by the off-site laboratory. Two (2) biased soil samples (9527-0002-016F and 9527-0002-017F) were collected and analyzed by the offsite laboratory for gamma spectroscopy. The implementation of survey specific quality control measures included the collection of two (2) samples (9527-0002-OOF and 9527-0002-01 IF for "split sample" analysis by the off-site laboratory.

The laboratory analyzed the fifteen (15) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy. Gamma spectroscopy analysis was performed to the required MDC. Gamma spectroscopy results identified some radionuclides 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 fifteen (15) samples. The mean of the results of gamma spectrometry analysis for each of the samples indicated Cs-137 at levels consistent with 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 the Operational DCGL. Gamma spectroscopy sample analysis did not require further investigation; however, investigation was required with the inclusion of those HTD radionuclides that exceeded the de-selection criteria of 5% and 10% (refer to Table 7 and Section 8).

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. Four (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.

QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. Thirteen percent (13%) 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 Assessmentfor Final Status Survey." There was acceptable agreement between the field split results for sample 9527-0002-01 IF. There was unacceptable agreement between the field split results for Cs-137 in sample 9527-0002-OO1F which was identified under Condition Report (CR) 05-078 1. Evaluation of the data for location 1 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 recalls that the rocky terrain and undergrowth made sample collection difficult. The sample analysis vendor, General Engineering Laboratories (GEL) -Charleston, South Carolina, 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 A sample was collected August 24, 2005 at a location exhibiting elevated readings during scanning (9527-0002-018F). The Daily Survey Journal describes the source as "no larger than a [sic] probe area", indicating that a small, discrete source of activity was present. Post sample collection scanning confirmed no that no elevated activity remained. The FSS Engineer at the time had the sample processed to include removal of the discrete entity, according to interviews with FSS Supervision and Health Physics Technicians present at the time. The remaining soil, following removal of the source of activity, was stored at the Emergency Operations Facility in a storage area. The final disposition of the discrete source is unknown. Gamma spectroscopy analysis was performed on the remaining soil on March 9, 2006 by the on-site laboratory to the required MDC. The samples results did not exceed 30% of the Operational DCGL. No further action or investigations were required (see Table 10).Revision 0 16 Revision 0 16 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD A sample was collected August 25, 2005 at a location exhibiting elevated readings during scanning (9527-0002-019F). Gamma spectroscopy analysis was performed by the off-site laboratory to the required MDC. The sample results did not exceed 40% of the Operational DCGL. No further action or investigations were required (see Table 10).Additional scanning was performed in two (2) small locations in March 2006 to obtain additional data relevant to the DQOs. The scanning was performed in two (2) strips approximately three (3) feet wide by thirty (30) feet long in scan area 3 and scan area 5. No elevated readings were identified. Confirmatory sampling was performed in March 2006 at sample location #4 when the Operational DCGL was found to have been exceeded. Two (2)samples were collected, were dried, and were analyzed by gamma spectroscopy to the required MDCs by the on-site laboratory (9527-0002-020F and 9527-0002-021F). The sample results did not exceed 33% of the Operational DCGL.No further action or investigations were required (see Table 10).Table 9 -Confirmatozy Sample Results Cs-137 Co-60 Fraction of the Sample Number pCig pCI/g DCGLO t 9527-0002-018F 1.18E-01 3.29E-01 0.316 9527-0002-019F 9.22E-01 3.76E-02 0.395 9527-0002-020F 6.88E-01 3.05E-02 0.297 9527-0002-021F 7.611E-01 3.10E-02 0.326 (1) The Operational DCGLs are 2.53 pCi/g for Cs-137 and 1.22 pCi/g for Co-60 used in conjunction with the unity rule 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 Four (4) HTD radionuclides were reported in concentrations exceeding the 5%and 10% rule for de-selection. Therefore, the individual Operational DCGLs for Sr-90, H-3, C-14 and Tc-99 were included into sample design in conjunction with the unity rule to ensure adequate survey design in accordance with the DQOs. The result of the COMPASS computer run showed adequate power and maintained the original fifteen (15) surface soil samples for non-parametric statistical testing.Revision 0 17 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD It was noted that all samples, including biased and investigatory, sent to the off-site laboratory were analyzed for H-3 and Sr-90. The analyses were not identified as being necessary for all samples by the DQOs, nor were they specified in the instructions of the FSS plan for completing the COC for the laboratory. The reason could have been a decision made by the FSS Engineer at the time (which is more conservative) who then forgot to pen and ink the FSS plan and record the basis in the FSS plan or in a Daily Survey Journal 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). 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 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.The range of the data, about 4.1 standard deviations, was not unusually large.The difference between the mean and median was 30% of the standard deviation which indicates positive skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot shows some positive skewness as confirmed by the calculated skew of 0.4 and is probably due to the differences in terrain and the collection of runoff.All data, assessments, and graphical representations are provided in Attachment 2.12. ANOMALIES No anomalies were noted.Revision 0 18 Revision 0 18 EAST MOUNTAIN SIDE SURVEY UNIT 9527-0002 RELEASE RECORD 13. CONCLUSION Survey Unit 9527-0002 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 was not required.The sample data passed the Sign Test. The null hypothesis was rejected.Graphical representation of data indicates some positive skewness 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. The survey unit was properly designated as Class 2.As discussed in Section 1, the survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-1. This survey unit is considered impacted by existing groundwater radioactive contamination as the survey unit is within the capture zone perimeter for an affected monitoring well. The dose contribution from the existing groundwater contamination will be addressed later and will be included to show compliance with site unrestricted release criteria as required by the LTP. This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area. The dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.14.
