SURVEY UNIT DESCRIPTION Survey Unit (SU) 9526-0002, (Northeast Mountain Side) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 6,068 m 2 (1.5 acres)of uninhabited, undeveloped land located about a tenth of a mile (0.09 miles)from the center of the Haddam Neck Plant (HNP) Containment Building (see Attachment 1-Figure 1). The Northeast Mountain Side Survey Unit 9526-0002 is bounded on the west by Survey Area 9521 and on the east by a long concrete utility vault containing telephone and electrical cable, which separates Survey Units 9526-0000 and 9526-0002.

The northern boundary is the fence separating SU 9526-0002 and 9527-0003.

An arbitrary line between SU 9526-0001 and 9526-0002, following the bed of a small stream, bounds the survey unit on the south. The area topography ranges from rocky, open spaces to steep, rocky hillsides that are heavily wooded' and overgrown with brush in many locations.

Some locations may be inaccessible or difficult to penetrate for practical or safety reasons.The reference coordinates associated with the Northeast Mountainside survey unit are E017 through E026 by. S074 'through S080 (refer to License Termination Plan Section 5.4.4); The reference 6bordinates 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).The historic files indicate that this area was originally included as part of the Class 3 SU 9526-0000.

During the FSS of Area 9526-0000, a soil sample identified Cs-137 above those concentrations identified at off site locations within the vicinity of the.HNP. Based on these sample results, a small section of Survey Unit 9526 was subdivided and a new Class 2 SU 9526-0001 was created. Survey Unit 9526-0001.

included the location where the elevated Cs-137 radioactivity was identified and confirmed.

Laterit was determined that the land area for SU 9526-0001 exceeded the License Termination Plan (LTP) size requirements for FSS Class 2 and the unit -was split into two units designated as 9526-0001 and 9526-0002.

Cable Vaults This survey unit contains a typical, concrete utility vault used for communications and electrical cable run, distribution and protection.

The vault, approximately eight feet in depth, is designed with connecting nodes with hatchway access and considered an OSHA permit required confined space.Cable penetrations are sealed to prevent in-leakage of groundwater and rain.Some of the vaults appear abandoned over the years and may or may not contain old cable runs. When last opened, just prior to this FSS, technicians observed that the access vault in this survey unit had become the home to several dozen or more indigenous snakes. The dark, dry, solar heated structure is an ideal reptilian habitat. No entries into the vaults have occurred within last Revision I 3 Revision I 3 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD seven or more years and during this FSS no entry was made, only the opening and "look-see" into the interior.

No "rad-related" plant postings or markings were observed in the interior.

The vault was closed and the exterior surveyed.This survey was evaluated and met the unconditional release criteria of the HNP decommissioning project. The cable vaults are referenced or discussed throughout this report. Copies of related surveys are provided in Attachment 1.2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification

"; The historical information and scoping analyses results provide sufficient data to designate SU 9526-0002 as Class 2 in November 2001.The "Classification Basis Summary" conducted for SU 9538-0000 consisted of: a) Areviewofthe lOCFR50.75 (g)(1)database, b) A review of the "Initial Characterization Report" and "Historic Site Assessment Supplemenlt, " c). Historic and current survey records review, d) Personal interviews, e) Visual inspections and a '"Valk down." A review of the 1OCFR50.75 (g) (1) database identified two radiological events associated with Survey Area 9526. Incident report Plant Incident Report (PIR)80-37 describes the discovery of radioactive particles found on the hillside and other areas of the site. The investigation into the incident concluded that the particles were most likely ejected from the primary vent stack because of several operational events in 1979. Isotopic analysis of the particles indicated that the short-lived fission products Ce-144 and Ru-106 dominated the particle radioactivity.

A comprehensive survey was performed in 1980 where all identified particles were removed at the time of detection; During that survey, essentially all of Survey Area 9526 was radiologically surveyed.The second event was detailed in the report Adverse Condition Report (ACR)97-0994. During the site characterization, radioactive material was found on the hillside area located immediately to the east of the station (Area 9526).Subsequently, in the fall of 1997, scoping surveys were performed on the hillside area and approximately forty-eight (48) soil samples were collected.

Sample analysis indicated Cs-137 as the primary isotope of concern. The average concentration of Cs-137 in the forty-eight (48) samples was 0.82 +/- 0.35 pCi/g. These values are consistent with the concentrations of Cs-137 found in soil at off site locations within the vicinity of the HNP as presented in Health Physics Technical Support Document (TSD) BCY-HP-0063, "Background Cs-137 Concentrations in Soil. " Revision I 4 Revision 1 4 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD A review of the "Initial and Supplemental Characterization Reports " as well as the previous "Classfi cation Basis Summaries" provided no additional information pertinent to classification.

Characterization efforts in nearby areas have included analysis for Hard-to-Detect (HTD) radionuclides.

In some cases, HTD radionuclides were reported above the accepted criteria for detection (i.e., a result greater than two standard deviations-2a uncertainty).

A comparison of HTD reported maximum concentrations to the soil Derived Concentration Guideline Levels (DCGLs)shows no impact on classification.

Seventeen (17) data points were used to determine the radiological concentration variability in this survey unit. The population data set included data from this and adjacent survey units collected during scoping and characterization.

All survey units included in this assessment were part of the original Survey Area 9526.Radionuclide-specific analyses of soil samples collected from this survey unit and adjacent land areas with similar history and physical characteristics have identified only a few of the radionuclides listed, principally'Cs'137 and Co-60 infrequently.

Analyses of soil samples ciollected during the FSS and follow-up investigation of Survey Area 9526 in November 2001 did not- identify a majority of the Table 2 listed radionuclides.

Only trace amounts of-Eu-155, Pu-238 and Pu-239/240 were reported.

However, the concentrations were well below the required sensitivities-and could represent statistical fluctuations'in background and therefore be "false positives".

The Eu-155 was reported at 0.187 pCi/g, which is <0.05% of the Base Case DCGL. Plutonium-238 and Pu-239/240 are 0.11% and 0.13% of the corresponding Base Case DCGL. The aggregate is below 10% as well.Seventeen (17) soil samples collected during characterization were used to determine the basic statistical quantities and variability.

The -results for Cs-137 included the two anomalous results from previous FSS activities in Survey Area 9526 (both were from the same location, one was a duplicate measurement).

The two (2) anomalous results increase the overall variability of Cs-137.Witho-ut the two (2) anomalous~results, the Cs-137 levels are consistent with those concentrations determined from off site locations as documented by Health Physics TSD BCY-HP-0063 (see Table 1). The range and standard deviation for the Co-60 shows large variability as expected since the data set included results for Co-60 whether or not this radionuclide was identified.

Cobalt-60 was identified in only a few soil samples with the highest reported concentration being 4% of the Table 2 Base Case DCGL.Revision 1 5 Revision I 5 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD Table 1 -Basis Statistical Quantities for Cesium-137 and Cobalt-60 from the Characterization Survey Cesium-137

Discussions with veteran HNP personnel provided no additional information relative to classification of SU 9526-0002.

The Site Radiological Release Supervisor performed a '"walkdown" of the area.The interior of the survey unit appears to-have been clear-cut in the uftility right-of-way. There were no obvious or perceptible signs of recent dumping or excavation activities.

At the time of FSS, the dose impact from groundwater contamination was not considered.

The classification basis shows that the expected residual.radioactivity in the survey unit would be below th'e site remediation criteria and are consistent with procedural guidance, thereby. sufficient to justify final designation as Class 2.3. DATA QUALITY OBJECTIVES (DQO)The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in SU 9526-0002 did not exceed the release criteria specified in the LTP, was below the 10 mrem/yr Administrative Level DCGLs, and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).FSS design and planning endorsed the use of 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-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 Revision l 6 Revision 1 6 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria.

Rejection of the null hypothesis would satisfy the release criteria objective of the FSS.The DQO process determined that Cs-137. and Co-60 would be the radionuclides of concern during the SU 9526-0002 FSS process. Additionally, to provide conservatism, the Base Case DCGLs for radionuclides in soil was reduced by 60% to establish the Administrative Level DCGL. As multiple radionuclides were assumed present, the "unity rule" or "sum of the fractions," described by Equation 5-32 of the LTP, was used to show compliance with the release criteria.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 performed before issue and after the instrument had been used. Control -and accountability of survey instruments were maintained to assure the quality and prevent the loss of data.Laboratory DQOs and analysis results were reported as actual calculated results.Results reported.

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 Final Status Survey Radiological Engineers when preparing survey plans for FSS, guidance is provided in Procedure RPM '5.1-11. By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP.The LTP specifies that scanning will be performed in a combination of systematic and judgmental measurement 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. Based on conditions found during the area inspection tours, five (5) areas, totaling 675.2 m 2 in area or 11.1% of the SU surface area, were selected for scanning.

These locations were determined to have the highest potential for elevated activity based on process knowledge and previous sampling results. Emphasis was given to flat open areas or runoff Revision I 8 Revision 1 8 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD routes from hillsides directly down wind from probable release pathways (e.g., Primary Vent Stack). Some of these locations, which were included in Scan Area 4, show evidence of elevated activity in the past. In addition, as part of design, scans were performed at each Sample Measurement Location (SML).Scans were also prescribed for a 1-meter radius around each random and biased SML.The utility poles and cable vaults readily indicate that service personnel accessed the area, albeit infrequently.

Based on historic data and potential for use, approximately 20% of the cable vault exteriors were surveyed at the time of FSS. In addition, Scan Area 3 is located adjacent to the cable vaults. Any anomalies encountered in this area during the scan would prompt further investigation of the cable vaults exteriors.

Seventeen (17) data points were used to determine the radiological concentration variability in this survey unit.Radionuclide-specific analyses of soil samples collected from this survey unit and adjacent land areas with similar history and physical characteristics have identified only a few radionuclides, principally Cs-137 and Co-60 infrequently.

The data collected prior .to -FSS indicated that the remaining eighteen (18)radionuclides listed in Table 2 would not be present in quantities greater than 5% of the applicable Base'Case DCGL in this survey unit at the time of FSS. It was unlikely that the aggregate concentration of the remaining radionuclides would exceed 10% of the DCGL; therefore, only Cs-137 and Co-60 were used in the survey planning of SU 9526-0002.

The use of the 5% and 10% rule is consistent with the development of surrogate ratio DCGLs as described in the LTP.Since multiple radionuclides were assumed present, the "uniity rule" or "sum of the fractions" was used to demonstrate compliance with the release criteria.Therefore, the Operational DCGL is considered "1." Surrogate DCGLs are not required for this survey. unit. because of the radionuclide specific analysis and radionuclide de-selection in accordance with the 5% and 10% rule.The Elevated-Measurement Comparison (EMC) does not apply to this survey unit since discrete, elevated areas of contamination are 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 Surface Samples for FSS. " Survey design specified seventeen (17) surface soil samples for the Sign Test non-parametric statistical testing.Revision 1 9 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD For the FSS, seven (7) biased soil SMLs were selected in areas based on available historical information and observations of the area made during area inspections and "walkdowns".

Three of the sample locations were areas near the drainpipes that are located near the cable vaults; two locations were along the fence line separating SU 9526-0002 from SU 9527-0003; and, the final two locations were selected from the areas formed by the separation of the vaults in areas indicating soil disturbance or at the discretion of the Radiological Engineer.Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for HTD analysis, two (2) soil samples or 12% were randomly selected for HTD radionuclide analysis by using the Microsoft Excel"RANDBETWEEN" function.

Each sample would be sent 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 12% of- seventeen (17) samples, rounded up to the next whole number.The grid pattern and locations of the soil samplestwere determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying and Marking Surface Sample Locaitions for FSS. " 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 location and scan areas were identified using AutoCAD-Lt 0 a commercially available plotting software with coordinates consistent with- the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample and scan locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Revision I 10 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD Table 3 -Sample Measurement Locations (SML) with Associated GPS Coordinates.

The Lower Bound of the Gray Region-(LBGR) was adjusted in accordance with Procedure RPM 5.1-11 to 0.5 to maintain ihe relative shift (A/aF) in the range of 1 and 3. In a Class 2 survey unit the median concentration is expected to be well below the LBGR, in which case a Prospective Power Curve would be unnecessary and was not generated.

The mean concentrations for Co-60 and Cs-137 identified during the scoping and characterization indicate this assumption to be true.Table 4 provides a synopsis of the survey design.Revision 1 11 Revision 1 11 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD Table 4 -Synopsis of the Survey Design Feature Design Criteria Basis Based on AutoCAD and Survey Unit Size 6,068 m 2 Visual Sample Plan calculations Type I (a) and Type It (bid Number of 17 error were 0.05; relative shift Measurements (A/a) set at 1.7 by procedure, the LBGR was set to 0.5.Grid Spacing 20.32 m Based on triangular grid Interval Spacing 17.6 m Based on triangular grid DCGL 1Operational DCGL applied to DCIfield data L 675.2 m 2 Based on likelihood of finding Scan Survey Coverage (11 1%) elevated readings in this.1 particular Class 2 survey unit Scan Investigation Detectable over Based on achieving the Level background Administrative Level DCGL (I) The Operational DCGL was based on achieving an administrative level that was 40%0 of the soil DCGL and assuming no impact from radioactive contamination in groundwater or from buried concrete debris.5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0000-00119-000.

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 between November 6 and December 6, 2001. FSS operations were suspended in late December due to weather and safety conditions.

The survey was resumed in April 2002 when the weather permitted.

Additional field activities occurred in 2004 under Addendum 1. The addendum was issued May 11, 2004 to collect investigation-or "confirmatory" soil samples. This is discussed further in Section 10.Five (5) land areas, Scan Areas 1 through 5, were marked out using GPS coordinates consistent with the Connecticut State Plane System and scanned for elevated readings (see Attachment 2 for Scan Area Results).

Scanning was performed with an-Eberline E-600 using a SPA-3 sodiumiodide 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. As provided by the FSSP, sample 025F was collected in Scan Area 3 at an elevated reading location.Revision 1 12 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD The access hatches for the cable vaults and. the vaults adjacent to Scan Area 3 were surveyed and documented in accordance with the HNP radiological control procedures.

Using GPS coordinates, SMLs were identified and marked with a surveyor's flag for identification.

At each SML, a one (1) meter radius around the sample flag was scanned for elevated radiation levels.Seventeen (17) surface soil samples were collected and-packaged in accordance with HNP Procedure RPM 5.1-3, "Collection of Surface and Subsurface Soil, Shoreline Sediment, Asphalt and Liquid. Samples for Scoping, Characterization and Final Status Survey," and FSS design. Soil 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 Scoping, Characterization and Findl Status Survey Samples. " Two (2) soil samples (015F and 017F) were randomly selected for HTD radionuclide analysis.Seven (7) biased samples were collected for analysis.

Three of the (3) biased samples (020F, 023F, 024F) were collected near the three drainpipes that are located near the utility vaults; tw6'(2) samples (021F, 022F) were collected along the fence line separating SU 9526-0002 from 9527-0003;-

and two (2)samples (018F, 019F) were collected from the areas formed by the branching of the telephone and electrical utilities vaults.Two (2) "split samples" were collected at SML 003F and 015F for analysis by.the off site laboratory.

6. SURVEY RESULTS No elevated areas were identified during scanning at the SMLs. Scan Area 3, 4, and 5 contained areas with elevated-readings, which prompted the collection of investigation samples from these areas.

The laboratory analyzed the seventeen (17) samples taken for non-parametric statistical testing, the associated duplicates, biased and scan area samples using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDC. Cesium-137 and Co-60 were the only gamma-emitting radionuclides detected at statistically significant concentrations and in most cases greater than the MDC.

Addendum 1 to the FSSP was issued to perform sampling at these locations.

Sections 8 and 12 provide details on this action.The off site laboratory processed two (2) samples -for HTD analysis including alpha spectroscopy, gas proportional counting and liquid scintillation depending on the radionuclide and the measurement method. In both samples, Sr-90 was the only HTD identified in significant quantities (results greater than two standard deviations-2a uncertainty).

The Sr-90 levels reported in association with the gamma emitting radionuclides present in the sample exceeded the investigation level for the Administrative Level DCGL. The investigation and confirmatory sampling results for samples 015F and 017F are discussed further in Sections 8 and 12.

The results of gamma spectrometry analyses of this sample indicated only Cs-137 at levels consistent with concentrations of Cs-137 found in soil at off site locations within the vicinity of the HNP. No further action or investigations were required.Revision 1 15 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD Three elevated locations were identified during the surveying of Scan Area 4.Samples 9526-0002-026F, 027F and 028F were obtained from these locations.

The results of gamma spectrometry analyses of these samples indicated Cs-137 at levels consistent with concentrations of Cs-137 found in soil at off site locations within the vicinity of the HNP. Cobalt-60 levels were less than 2% of the Administrative Level DCGLck 0 o. No further action or investigations were required.One elevated location was identified during the surveying of Scan Area 5.Sample 9526-0002-029F was collected at this location.

Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey," determined that Revision I 16 Revision 1 16 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD 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 change made from the LTP, prior to this FSS, was a decrease in the concentrations for the Base Case DCGLSOS. The LTP presents DCGLs that correspond to a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr. This survey unit was evaluated against Administrative Level DCGLs that correspond to 10 mrem/yr.To perform confirmatory sampling at locations where soil analysis have exceeded the investigation level specified in the FSSP, Addendum I to the FSSP was issued in May 2004 to take verification samples at locations 9526-0002-015F, 016F and 017F.During data review, the elevated sample results from-three (3) areas prompted confirmatory sampling at locations' 9526-0002-015F, 016F and 017F. The results of the confirmatory sampling Were included in the statistical analysis and the Sign Test with the previous data being excluded as suspect.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 designi had adequate power as indicated by the Retrospective Power Curve. The Sign Test was.performed on the data and compared to the original assumptions 6f the DQOs. All sample results were less than the release criteria.

Therefore, 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 converting the data into units relative to the release criteria (i.e., pCi/g) and calculating basic statistical quantities (e.g., mean, median, standard deviation).

For Cs-137, the sample standard deviation was less than the value used for the survey design. This indicates that a sufficient number of samples were collected to achieve the desired power. The range of the data, about three (3) standard deviations, was not unusually large. The difference between the mean and median was about 3% of the standard deviation.

The frequency plot indicates that the data is skewed positive.

Analysis of the data utilizing a cumulative frequency distribution indicates that the data set exhibits a "somewhat flat" distribution with "outliers" both high and low.Revision I 17 Revision I 17 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD For Co-60, the sample standard deviation was less than the value used for the survey design. This indicates that a sufficient number of samples were collected to achieve the desired power. The range of the data was about 3.5 standard deviations.

The difference between the mean and median was 40% of the standard deviation.

The frequency plot indicates that the data is skewed positive since most of the data values were negative or below MDC. Analysis of the data set utilizing a Cumulative Frequency Distribution (CFD) indicates six samples that are "outliers" of the distribution.

The data set exhibits a "flatter" than normal distribution; however, when the negative sample values are removed from the data set and the remaining data analyzed with the CFD, the sample results are somewhat normally distributed around the mean.All data, assessments and graphical representations are provided in Attachment 2.12. ANOMALIES All data is considered valid including negative values, zeros, values reported below the MDC and values reported with uncertainties greater than two standard deviations.

Some radionuclides have been irported at low concentrations that are statistically significant at the 95% confidence level, but with a relatively high level of uncertainty.

Based upon the confirmatory analysis of samples 9526-0002-Q015F, Oi6F and 017F, the initial lab results were considered as "suspect" and hot included in the data evaluation and analysis.

No further action was required.Gamma spectroscopy results for all samples identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two standard deviations-2a uncertainty).

Cesium-134 was frequently identified in sample results; whereas, Am-241, Eu-154, Eu-155 and Nb-94 were identified sporadically.

The off site laboratory data qualifier unit shows that these radionuclides were analyzed for, however, either the result was less than the MDC or the gamma software did not identify the radionublide.

These very low-level "detections" may be attributed to false positive noise at the lower limit of the measuring technique.

Hard-to-Detect analyses results identified Sr-90 in three samples. The Sr-90 value compares favorably with research conducted in other regional areas concerning fallout resultant from nuclear testing in the past as referenced in EPRI Technical Report 1003030, "Determining Background Radiation Levels in Support of Decommissioning Nuclear Powver Plants." No further actions were taken or needed.The data shows that the quantities of identified radionuclides do not represent quantities that would increase the requisite number of samples for non-parametric statistical sampling or cause the survey unit to fail to meet the Revision I 18 Revision 1 18 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0002 RELEASE RECORD release criteria.

Most radionuclides were reported at levels near or below the required MDC.13. CONCLUSION Survey Unit 9526-0002 has met the DQOs of the Final Status Survey. For this survey unit, the ALARA criteria for soils as specified in Section 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.Although several localized areas exceeded the Administrative Level DCGLSOiJ, confirmatory samples could not verify the initial results. Evaluation of the final data shows that none of the FSS design radionuclides or HTD soil concentration' values exceeded the Operational DCGL, or unity. No large anomalies were observed in the graphical representation of the data. The survey unit was properly designated as Class 2. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.This survey unit is not considered impacted by radioactive contamination in.groundwater based on location, topography and current hydro-geologic sampling data as referenced in Health Physics TSD CY-HP-0193, "Assessment of Existing Groundwvater Dose for Phase II Release Areas of the Final Status Survey Report.

Thc approach. "Law ofPropagation of Errors", Involves the Identification of all variables in an analytical method which are used to derive a resuIL These variables arc related to the Analytical result (R) by some functional relationship.

R = constants

f(x,y.z,).

The components (x,y,z) arc evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (ua are then combined using a statistical model that prmvides the most probable overall uncertainty value. All component uncertainties are categorized as typc A, evaluated by statistical methods, or type B. cvaluated by other means. Uncertainties not included in the components.

such as sample homogeneity, nre combined with the component uncertainty as the square root of the sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (u) multiplied by the coverage factor (1,2, or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included in the standard deviation.

The approach, "Law of Propagation of Errors", involves the identification of all variables in an nnalytical method which are used to dcrive a result. These variables are related to thc analytical rcsult (R) by some functional relationship, R = constants

ixy,z,...).

1he components (xyz) arm evaluatcd to dctermine their contribution to the overall method uncertainty.

The individual component uncertaintics (uO) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the components.

such ns sample homogeneity, arc combined with the component uncertainty as the square root of the sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (uj multiplied by the coverage factor (l.2. or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties arc all other random or non-random components that arc not included in thc standard deviation.

Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in 'WIST Technical Note 1297, 1994 Edition"'.

The approach.

'Law of Propagation of Errors, involves the identification of all variables in an analytical method which are used to derive a resulL These variables are related to the analytical result (R) by some functional relationship, R = constants

f(x,yz,...).

The components (xyz) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertaintics (u 1) arc then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not Included in the components, such us sample homogeneity, are combined with the component uncertainty as the square root of the sum--i l the-squarts of the individual uncertainties.

The uncertainty associated with the derived result Is the cumbined uncertainty (uj multiplied by the coverage factor (1,2, or 3).NVhen three or more sample replicates are used to derive the analytical result, the type A unrenainty Is the standard deviation of the mean value (Slvn), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included in the standard deviation.

The derivation of the general 'Law of Propagation of Errors' equations and specific example are available (n request.L-5Th Rfchiand runZU.(;wrnilllf v.3.72 6 STL RICHLAIND Remort Definitions Action I.eY Batch BiUS COC No Count Error (Rs)Total Uncert (Us)* i,. Coinbhled UCUnertainty.
