SURVEY UNIT DESCRIPTION Survey Unit (SU) 9526-0001, (Northeast Mountain Side) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 6,535 m 2 (1.6 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). Survey Unit 9526-0001 is bounded on the west by SU 9521-0000 and on the east by SU 9526-0000.

The northern boundary follows the bed of a small stream. SU 9526-0002 bounds the southern border. The area topography ranges from relatively flat open spaces to steep, rocky hillsides that are heavily wooded and overgrown with brush in several locations.

The topography of the upper portion of this survey unit is mildly sloping to the west.Most of this area is wooded and covered with dense brush interspersed with patches of exposed rock, a small stream and a stone wall. In the relatively flat section of the survey unit near Cove Road, three soil mounds where dumping or excavation activities occurred are visible.The reference coordinates associated with SU 9526-0001 are E019 through E021 by S080 through S083 (see 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).The historic files indicate that this area was originally included as part of the Class 3 SU 9526-0000.

During the FSS of SU 9526-0000, a soil sample identified Cs-137 above those concentrations identified at off site locations within the vicinity within the vicinity of the HNP as presented in Health Physics Technical Support Document (TSD) BCY-HP-0063, "Background Cs-137 Concentrations in Soil." Based on these sample results, a small section of Survey Unit 9526-0000 was subdivided and a new Class 2 SU 9526-0001 was created. Later, it 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.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classification. " The data analysis completed for the classification SU 9526-0001 and 0002 were considered equivalent.

The topography and locations of these units is generally the same, which allowed for the characterization data to be managed as a combined survey area. The historical information and scoping results provide sufficient data to designate SU 9526-0001 as Class 2 in November 2001.Revision 1 3 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD The "Classifi cation Basis Summary" conducted for SU 9538-0000 consisted of: a) A review of the 1OCFR50.75 (g) database, b) A review of the "Initial Characterization Report" and "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Personal interviews, e) Visual inspections and a "walk down." A review of the IOCFR50.75 (g) database identified two radiological events associated with Survey Area 9526. 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 as a result 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 scanned.The second event was detailed in the 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 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 TSD BCY-HP-0063.

A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classi(Ication 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 uncertainty).

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

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 collected 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-Revision I 4 Revision 1 4 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD 238 and Pu-239/240 were reported.

However, the concentrations were 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) samples 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 anomalous results increase the overall variability of Cs-137. Without the two 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.

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 Base Case shown in Table 2.Table 1 -Basis Statistical Quantities for Cesium-137 and Cobalt-60 from the Characterization Survey Cesium-137 Cobalt-60 Parameter (pCilg) (pCi/g)Minimum Value: 0.1368 0.00482 Maximum Value: 3.89 0.15 Mean: 0.9496 0.03229 Median: 0.7294 0.0213 Standard Deviation:

0.9439 0.03644 Measured Standard Deviation 0.30 of the weighted sum('): (1) MARSSIM Section 1.1 1.3 describes the use of the measured standard deviation of the weighted sum when measured concentrations of the various radionuclides are assumed to be uncorrelated (i.e., there is no fixed ratio between the concentrations).

Discussions with veteran HNP personnel provided no additional information relative to classification of SU 9526-0001.

The Site Radiological Release Supervisor performed a "walkdown" of the area prior to classification.

The interior of the survey unit is wooded with dense brushy undergrowth interspersed with patches of exposed rock, a small stream and stone wall. In a relatively flat section of the survey unit near Cove Road are three mounds of soil where dumping and excavation seems to have occurred.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 the site remediation criteria and Revision 1 5s NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD 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 9526-0001 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 5.1-11, "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.The DQO process determined that Cs-137 and Co-60 would be the radionuclides of concern during the 9526-0001 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 to be 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 as <MDC (i.e., less than Minimum Detectable Concentration) would not be accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result and uncertainty of two standard deviations (2a), laboratory data qualifiers, units and the required and observed MDC (see Table 2).Revision I 6 Revision 1 6 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD Table 2 -FSS DCGL Values and Required Minimum Detectable Concentrations Radionuclide Base Case Soil Adninistrative Level Required MDC DCGL (pCilg) DCGL (pCilg) (2) (pCilg) (3 H-3 4.12E+02 1.65E+02 1.65E+O1 C-14 5.66E+00 2.26E+00 2.26E-01 Mn-54 1.74E+01 6.96E+00 6.96E-01 Fe-55 2.74E+04 1.lOE+04 I.IOE+03 Co-60 3.81E+00 1.52E+00 1.52E-O1 Ag-108m 7.14E+00 2.86E+00 2.86E-01 Ni-63 7.23E+02 2.89E1302 2.89E+O1 Sr-90 1.551E+O0 6.20E-01 6.20E-02 Nb-94 7.12E+00 2.85E+00 2.85E-O01 Tc-99 1.26EfOI 5.04E+00 5.04E-01 Cs-134 4.67E+00 1.87E+o0 1.87E-01 Cs-137 7.91 E+O0 3.16E+00 3.16E-OI Eu-152 1.OIE+O1 4.04E+00 4.04E-01 Eu-154 9.29E+00 3.72E+00 3.72E-O01 Eu-i55 3.92E+02 1.57E+02 1.57E+OI1 Pu-238 2.96E+01 1.188E+01 1.18E+00 Pu-239/240 2.67E+01 1.07E+0 I 1.07E+0O Pu-241 8.70E+02 3.48E+02 3.48E+01 Am-241 2.58E+01 1.03E1+01 1.03E+00 Cm-243/244 2.90E+01 1.16E+ 01 1.1 6E+OO (1) The Base Case DCGLs for soil are specified by the LTP in Chapter 6.(2) The Administrative Level DCGL is 40% of the Base Case DCGL.(3) The required MDC was 10% of the Administrative Level DCGL.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 Final Status Survey 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. Based on conditions found during the area inspection tours, five (5) areas, totaling 663.36m 2 in area or 10.2% of the SU surface area, were selected for scanning.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. Areas around piles, trenches and access points where it was determined to have the highest potential for elevated activity based on Revision I 7 Revision 1 7 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD process knowledge and previous sampling results were selected.

For example, Scan Area 4 was selected where Co-60 was previously found during characterization.

In addition, consideration was given to locations that are adjacent to areas containing plant radioactivity or elevated activity.

The shape of several scan locations reflects the difficult topography of the region (e.g., exposed rock cliffs with steep banks). The shape had little impact on achieving the survey objectives since the locations were biased to identify areas with the highest potential for elevated activity.

Scans were also prescribed for a 1-meter radius around each random and biased Sample Measurement Location (SML).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 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%; therefore, only Cs-137 and Co-60 were used in the survey planning of SU 9526-0001.

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 to be present, the "unity rule" or"sum of the fractions" was used to demonstrate compliance with the release criteria.

Therefore, the Operational DCGL is considered to be "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.For the FSS, five (5) biased soil SMLs were selected in the soil mounds and a trench found near Cove Road identified during the walkdown.Revision I 8 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD 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 Samnple 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 MicrosoftD 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 samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifring and Marking Surface Sample Locations 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 9 Revision I 9 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 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 the relative shift (A/cr) in the range of I and 3. In a Class 2 survey unit the median concentration is expected to be 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 I 10 Revision 1 10 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD Table 4 -Syn psis of the Survey Design Feature Design Criteria Basis Based on AutoCAD and Survey Unit Size 6,535 m 2 Visual Sample Plan calculations Type I (a) and Type II (1)error were 0.05; relative shift Number of Measurements 17 (A/a) set at 1.7 by procedure, the LBGR was set to 0.5.Grid Spacing 25.4 m Based on triangular grid Interval Spacing 22.0 m Based on triangular grid Operational DCGL applied DCGL I to field data (1)Based on likelihood of 663 m 2 finding elevated readings in Scan Survey Coverage (10%) this particular Class 2 survey unit Detectable over Based on achieving the Scan Investigation Level background Administrative Level DCGL (I) The Operational DCGL was based on achieving an administrative level that was 40% 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-0000-001 19-000. 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.Additional field activities occurred in May 2004 under a separate addendum to the sample plan. Addendum 1 was issued May 11, 2004 to collect investigation or "confirmatory" soil samples. This is discussed further in Sections 8 and 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 2x2 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, 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.Revision 1 11 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD Seventeen (17) surface soil samples were collected and packaged in accordance with 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 Final Statues Survey Samples." Two (2) soil samples (002F and 010F) were randomly selected for HTD radionuclide analysis.Five (5) biased soil samples (018F, 019F, 020F, 021F, 022F) were collected in the small piles and a trench found near Cove road.Two (2) "split samples" were collected at SML 00WF and 006F for analysis by the off site laboratory.

6. SURVEY RESULTS No elevated areas were identified during scanning at the SMLs. Scan Area 2, 3, 4, and 5 contained areas with elevated readings, which prompted the collection of investigation soil samples from these areas. The investigation results are discussed in Section 8 of this report. Table 5 provides a summary of the scan area survey.

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

Gamma spectroscopy analysis was performed to the required MDC.

QUALITY CONTROL The off site laboratory processed the split soil samples and performed gamma spectroscopy analysis.

Twenty percent (20%) of the soil 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 Procedure RPM 5.1-24. There was acceptable agreement between field split results. The sample analysis vendor, STL-Richland, maintains quality assurance and quality control plans as part of normal operation.

Refer to Attachment 2 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS During Area 2 scanning, four (4) locations above the scan investigation level were identified and designated ER-0001 through ER-0004. Samples 023F, 024F and 025F were collected from these locations.

ER-0004 was not sampled but indicated the presence of a rock formation that contained naturally occurring radioactive materials.

The results of gamma spectrometry analyses of these soil samples 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.An elevated location, above the scan investigation level, was identified in Areas 3, 4 and 5. Samples 026F, 027F and 028F were collected from these locations.

The results of gamma spectrometry analyses of these soil samples indicate 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 did not exceed 1.3% of the DCGLco-o.

Based on analytical results, no further action was required.

This prompted an evaluation, which basically requires the area to be re-sampled for results confirmation (see Table 10). Addendum I to the FSSP was issued May 11, 2004. SML 002F area was re-sampled for analysis and submitted to General Engineering Laboratories-LLC, Charleston, S.C. The off site laboratory processed the soil samples for HTD Sr-90 and gamma spectrometry analyses.The confirmatory sample results were below any required investigation levels established by the FSSP and LTP. The initial sample results for 002F could not be verified.

No further action was required or taken.Table 10- Confirmatory Analysis Results for HTD and Gamma Emitting Radionuclides Compared to the DCGL.-Cs-137 l Sr-90 fDCGL~'Sample Number &D o th G L 9526-0001-002F 0.409 0.0847 0.266 (I) f-1CGLfraction of the Administrative Level DCGL 9. REMEDIATION AND RESULTS Historically, no remediation 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 Rernediation 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 change made from the LTP, prior to this FSS, was a decrease in the concentrations for the Base Case DCGLSOilS.

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 for evaluation as specified in the FSSP, Revision 1 15 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD Addendum 1 to the FSSP was issued in May 2004 to collect a verification sample from location 9526-0000-002F.

This sampling was completed the same day that the addendum was issued.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. 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 3 standard deviations, was not unusually large. The difference between the mean and median was 12% of the standard deviation.

The frequency plot indicates that the data is slightly skewed positive.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 is about 3.8 standard deviations.

The difference between the mean and median was 11% of the standard deviation.

The frequency plot indicates that the data is slightly skewed negative.The frequency plot indicates a distribution of generally standard proportions with outliers both high and low. The samples represented by the low outliers may be attributed to the area being disturbed or the soil being removed or mixed with other materials, or lab variability in the analytical method. The samples in the high outlier locations were from the close vicinity of a stream that drains a vast open area and represent typical variability found in this type of terrain.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 Revision I 16 Revision 1 16 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD standard deviations.

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

Gamma spectroscopy results for all soil samples identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than 2 standard deviations 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 radionuclide.

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 one sample. 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 Power Plants." No further actions were taken or needed.Although present in sample 002F, the Pu-239/240 quantity was less than 1% of the Administrative Level DCGL. The likely source of Pu-239/240 was the release of plutonium from past atmospheric nuclear weapons testing and burn-up and vaporization of the United States SNAP 17A satellite in the atmosphere given the extremely low levels reported.During the initial data review, it was noted that the required MDC for Sr-90 (sample OIOF) in the February 27, 2004 report was not achieved by the off site laboratory.

The lab also reported that the sample aliquot was taken in the improper amount in order to meet the requested MDC. The lab stated that since the results were greater than the Minimum Detectable Activity (MDA) the data was accepted.

The lab reported value of 0.15 pCi/g Sr-90 meets the MDC value required by the LTP (10% of the Base Case DCGL of the 25 mrem/yr value)and is considered acceptable.

In the February 27, 2004 lab report for sample 9526-0001-OIOF, Sr-90 analytical results were 5.29 times the DCGLSr.90.

This greatly exceeded the typical Cs-137/Sr-90 ratios (4:1) previously found in the outland areas around HNP. A request to re-analyze the sample was issued to the STL laboratory.

The re-analysis report dated March 26, 2004 indicates that Sr-90 for sample OlOF was below the reported MDCs,9 0 of 0.156 pCi/g. Although this MDC is above the Table 2 required value of 0.062 pCi/g Sr-90, the results were considered acceptable as meeting the criteria for MDC in accordance with the LTP.Revision I 17 Revision 1 17 NORTHEAST MOUNTAIN SIDE SURVEY UNIT 9526-0001 RELEASE RECORD Conservatively estimated, the final calculated DCGL fraction for OIOF was 0.81 or 81% of the 10 mrem/yr Administrative Level DCGL. This value assumes that Sr-90 was present at the reported MDC level of 0.156 pCi/g. No further action was required.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 release criteria.

Most radionuclides were reported at levels near or below the required MDC.During the survey of Scan Area 2 (ER-0004), an outcropping of rock was identified as containing naturally occurring radioactive materials.

Initial survey with the Eberline E-600 using a SPA-3 2x2 sodium iodide detector gave a reading of 12,700 counts per minute (cpm). Geological occurrences of this type are discussed in the Health Physics TSD CY-HP-0150, "Investigation of Rock Outcropping Exhibiting Elevated Activity." This area designated as ER-0004 was not sampled, but noted.13. CONCLUSION Survey Unit 9526-0001 has met the DQOs of the FSS. For this survey unit, the ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.The Elevated Measurement Comparison and remediation was not required.The sample data passed the Sign Test. The null hypothesis was rejected.Evaluation of the data shows that none of the FSS design radionuclides or HTD soil concentration values exceeded the Operational DCGL of "1" 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 Groundwater Dose for Phase II Release Areas of the Final Status Survey Report.

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

• f(x,y,z,...).

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

The individual component uncertaInties (u 1) 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 as sample homogeneity, arc combined with the component uncertainly as the square root or 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 or the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties are DlD other random or non-random components that are not included in the standard deviation.

Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in "NIST 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 result. These variables are related to the analytical result (R) by some functional relationship, R = constants

• f(x,yz,...).

The components (x,yz) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (uj) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated bv 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-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (uj) 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.

Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in 'NIST 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 arc related to the analytical result (R) by some functional relationship, R = constants

• f(xy,z,...).

The components (xy~z) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (u 1) 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 as sample homogeneity, are 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 (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 (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 on request.5. 1 ST1 Rlchland ratGenerallnfo Y3.72 4 Report Definitions Action Lev An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action Level.
