SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD

1. SURVEY UNIT DESCRIPTION Survey Unit (SU) 9535-0002, (Southeast Landfill Area) is designated as Final Status Survey (FSS) Class 2 and consists of approximately 3,320 m (0.82 acres) of uninhabited, undeveloped land located 0.81 miles from the center of the Haddam Neck Plant (HNP) Containment Building (see Attachment 1, Figure 1). A Class 3 survey unit (9524-0000) encompasses the Survey Area 9535 in whole. The Survey Area 9535 is divided east to west into two survey units. The southern parcel is the Class 1 SU 9535-0001. The northern section is SU 9535-0002. The Survey Area 9535 is located north of the pistol range, and between Dibble Creek and the Salmon River. It is 45 meters upgrade from and east of the creek and separated from the Salmon River by a tall, sandy, tree-lined ridge. The topography of the area has changed considerably as a result of material and spoils removal from the area. The debris piles are gone, materials removed and the area graded. Most of the area is sand based, although trenching identified some large rock masses.

The reference coordinates associated with SU 9535-0002 are E050 through E055 by S128 through S133 (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, in the past, vehicle barriers were used to restrict public access to the land space of Survey Area 9535. The landfill, due to its proximity to the road and relatively level surface, was a convenient place to dispose truckloads of construction materials and debris during plant construction and operation. Occasionally small amounts of miscellaneous material were mixed in with fill material. The area has a rhomboid shape that was fenced and posted, "Caution, Radioactive Materials", after the discovery of radioactive soil there.

Following the remedial action and remedial action surveys, the fence and posting were no longer necessary and removed (refer to HP Technical Support Document (TSD) CY-HP-0154).

Non-radiological remediation was performed in the landfill area in 2003 using cleanup criteria specified by the Regulatory Affairs group (refer to memorandum RA-CY-03-058, CY). The scope for this project was the physical investigation and cleanup of the landfill to include the removal of all manmade materials, other than unpainted concrete, from the area. Blast rock also remained in the area.

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 provided sufficient data to designate SU 9535-0002 as Class 2 in April 2004.

The "ClassificationBasis Summary" conducted for SU 9535-0002 consisted of:

Revision I 3 Revision 1 3

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD a) A review ofthe 10CFR50.75(g)(1) 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 10CFR50.75(g)(1) database identified several radiological events pertinent to Survey Area 9535. The database did not distinguish the events between SU 9535-0001 and SU 9535-0002. The final determination was to separate the survey area such that the elevated activity events would not be in the land space of SU 9535-0002. The following events are under the report of "Survey Area 9535-0000":

a) ACR 97-0450, 7/17/1997 - Contaminated material found outside the protected area. As part of the Site Characterization Survey, contaminated material and soil were identified in the rifle area. During the implementation of a scoping survey, elevated activity was detected in the landfill adjacent to the rifle range. A subsequent investigation identified two locations of fixed contamination, insulation material and a concrete block.

b) ACR 97-0785, 9/24/1997 - Follow-up to ACR 97-0450. An assessment of the soil indicates that the amount of radioactivity counted in the soil may exceed the limits of 10CFR20.2203(a)(3)(ii).

c) Results of Scoping Survey, 9/1/1998 - Results of scoping surveys performed for decommissioning characterization data.

d) Duratek Shooting Range, 12/7/1999 - Characterization survey to determine the extent and magnitude of plant related radionuclides within the Shooting Range Landfill.

Review of the 10CFR50.75(g)(1) database concluded that the fundamental event was the identification of radioactive material in July, 1997. The remaining items reflect subsequent characterization findings and a couple of non-radiological material discoveries (e.g., asbestos and hydraulic oil).

A review of the "Initial and Supplemental CharacterizationReports," "Historic Site Assessment Supplement," as well as the previous "Classification Basis Suumnaries" provided no additional information pertinent to classification.

A survey plan was initiated and executed in late 1997 to determine existing conditions and obtain radiological data for scoping. Radiological results from the initial scoping surveys indicated the presence of both Co-60 and Cs-137 in soil.

The site characterization group performed radiological surveys of the landfill area with confirmatory surveys conducted by Oak Ridge Institute for Science and Engineering (ORISE). The initial characterization surveys were completed in 1997.

Revision 1 4 Revision 1 4

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD Results of the radiological survey and ground penetrating radar survey established the size of the landfill area to be approximately 5,000 square meters and an approximate depth of 3 meters.

A characterization study was performed in 1999 to determine the extent and magnitude of the plant-related radionuclides in the area.' Soil sample results for SU 9535-0002 did not identify plant-related radionuclides (i.e., Cs-137 or Co-60) above the survey design criteria (i.e., 1.68 pCi/g for Cs-137 and 0.15 pCi/g for Co-60) in the ten (10) soil samples collected. Note, the survey design assumed that Cs-137 results below 1.68 pCi/g were attributed to fallout from atmospheric nuclear testing.

A characterization plan to support FSS design was developed and implemented on November 7, 2003 and November 8, 2003. Excavation and trenching was performed in this survey unit for the purposes of removing manageable spoils and materials (e.g., concrete, asphalt, metal, etc.). The materials were surveyed for radiological contamination in accordance with health physics procedures. No materials were found to exceed the radiological release criteria for unrestricted use.

Judgmental scan measurements were performed in the area, particularly near suspect items (e.g., crushed barrel, PVC piping, buckets). Three (3) areas were identified as having exceeded twice ambient background and were marked for biased sampling. Seven (7) other locations were selected for a total of ten sample locations. The ten (10) soil samples were collected and analyzed on-site using gamma spectroscopy. Sample results for Cs-137 and Co-60 are provided in Table 1.

Table 1 - Basic Statistical Quantities for Cs-137 and Co-60 Derived from the Characterization Survey Parameter Cs-137 (pCi/g) Co-60 (pCi/g)

(1-17) describes the use of the measurement 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).

A review of the soil relocation files shows that soil and spoils were transported to the general vicinity of the Southeast Landfill as early as 1976. Specific details relevant to date or time period and exact location or placement were not available.

Personnel interviews with HNP veteran personnel were conducted during the historical site assessment to ascertain the history of the Southeast Landfill.

Shooting Range Landfill Characterization Survey Report; December 1999.

Revision I 5 Revision 1 5

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD Individuals responding to the questionnaire stated that spoils originating from construction activities such as new building construction, addition to existing buildings and general site maintenance and repairs were brought to the shooting range landfill.

A Final Status Survey Engineer (FSSE) performed a visual inspection and "walkdown" in April 2004. The visual inspection and walkdown did not conclude any observations impacting the classification of the survey unit.

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 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 9535-0002 did not exceed the release criteria specified in the LTP, was below the 10 mrem/yr Administrative Level Derived Concentration Guideline Levels (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, "Preparationof Final Status Survey Plans" and the "Multi-Agency Radiation Survey and Site Investigation Manuarl (MARSSIM). A summary of the main features of the DQO process is 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 FSS process for SU 9535-0002. To provide conservatism, the Base Case DCGLs for radionuclides in soil were reduced by 60% to establish the Administrative Level DCGLs. 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.

Revision I 6 Revision 1 6

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD 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 less than Minimum Detectable Concentration (<MDC) 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 (Table 2).

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 FSSE 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 Class 2 land areas and cover 10% to 100% of the area. The fraction of the scanning coverage was determined during the DQO process and locations based on the likelihood of finding elevated activity during the FSS.

Survey data collected to date (including soil samples and survey for radioactive contamination on removed material) indicates a low probability of finding elevated areas of residual radioactivity relative to the DCGL. Nevertheless, the historical use of the landfill to store materials and spoils from construction projects and the relatively small area of the survey unit justify scan coverage representing 100% of the total area. For a visual depiction of the scan area locations refer to Attachment 1, Figure 2.

The FSSP required a radiation scan of one (1) meter radius around each Sample Measurement Location (SML) to identify areas of elevated activity. Sample measurement locations within a surveyed FSS scan area did not required a duplicate scan survey.

Ten (10) data points were used to determine the radiological concentration variability in this survey unit. The population data set was from the characterization survey soil samples with sample locations from within the boundaries of 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%;

therefore, only Cs-137 and Co-60 were used in the survey planning of SU 9535-0002. 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 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".

Revision 1 8 Revision 1 8

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD Surrogate DCGLs are not required for this survey unit because of radionuclide specific analysis and radionuclide deselection 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.

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." In accordance with Procedure RPM 5.1-11 the Lower Boundary of the Gray Region (LBGR) was adjusted from 0.5 to 0.92 to maintain the relative shift (A./a) in the range of 1 to 3. Survey design specified fifteen (15) surface soil samples for the Sign Test non-parametric statistical testing.

For the FSS, three (3) biased soil SMLs were incorporated in the survey design.

The basis for this professional judgment decision was historical documentation review and process knowledge.

Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for HTD analysis, two (2) soil samples or 13% were randomly selected for HTD radionuclide analysis 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 14% of fifteen samples, rounded up to the next whole number.

The grid pattern and location 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 FSS". Pacific Northwest National Laboratory (PNNL) created VSP for the United States Department of Energy Input parameters included a systematic grid spacing consisting of a triangular pitch pattern, and a random starting point which is appropriate for a Class 2 survey unit. .

Sample locations and scan areas were identified using AutoCAD-LtO, a commercially available plotting software with coordinates consistent with the Connecticut State Plane Coordinate System. The FSSP specified the use of a Revision I 9 Revision 1 9

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD Global Positioning System (GPS) to locate SMLs and scan area locations in the field. The GPS coordinates for the fifteen (15) SMLs designed for the non-parametric statistical testing are provided in Table 3.

In a Class 2 survey unit the median concentration is expected to be below the LBGR. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The Prospective Power Curve showed adequate power for the survey design. The final remedial action survey data of this survey unit indicated the mean concentrations of Co-60 and Cs-137 is below the LBGR. Table 4 provides a synopsis of the FSS design.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-9535-01017-000. The WP&IR package included a detailed FSSP, job safety analysis, job planning checklist and related procedures to be used 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 April 28 and May 10, 2004.

Using the GPS, the scan area and SMLs were identified and marked with surveyor's flags. A 100% scan survey of SU 9535-0002 was performed and evaluated for elevated readings. See Attachment 2 for scan area results. The survey unit was divided north to south into two halves and surveyed in one meter strips east to west.

Given the shape of the northern tip of the survey unit a few sections had distinct shapes not sensibly receptive to the one meter strip methodology. Scan surveys were performed with an Eberline E-600 using a SPA-3 2"x2" 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 feasible and was moved at a scan speed of about 0.5 meters per second.

The fifteen (15) surface soil samples were collected and packaged in accordance with the FSS design and the Procedure RPM 5.1-3, "Collection of Surface and Subsurface Soil, Shoreline Sediment, Asphalt and Liquid Samples for Scoping, Characterizationand Final Status Survey", and FSS Design. Soil samples were Revision 1 11

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD controlled, transported, stored, and transferred to the off site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Scoping, Characterization and Final Status Survey Samples."

Two (2) soil samples, 9535-0002-004F, and 006F, were collected and sent to the off site laboratory for gamma spectroscopy and HTD radionuclide analysis.

Three (3) biased soil samples were collected, 9535-0002-016F through 018F, and sent to the offsite laboratory for gamma spectroscopy analysis. See Attachment 1, Figure 5 for a visual depiction.

Two (2) field "split samples", 9535-0002-008F/FS and 009F/FS, were collected for analysis by the offsite laboratory.

6. SURVEY RESULTS No elevated areas were identified during scanning at the SMLs. The Scan Area 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.

All scan area results are provided in Attachment 2.

The laboratory analyzed the fifteen (15) 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.

The results of gamma spectrometry analysis for all of the 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 (Health Physics TSD BYC-HP-0063). The Revision I 12 Revision 1 12

The maximum reported f-DCGL for any individual soil sample was 12%. Validation/verification of the survey data, a Data Quality Assessment (DQA) and the Sign Test were performed. The data passed the Sign Test. Refer to Attachment 2 for data and DQA results.

7. QUALITY CONTROL The off site laboratory processed the "split samples" and performed gamma spectroscopy analysis. Thirteen percent (13%) of the soil samples were selected for analysis which exceeds the minimum of 5% which is 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. General Engineering Laboratories, LLC, maintains quality assurance and quality control plans as part of normal operation.

Refer to Attachment 2 for data and data quality control analysis results.

8. INVESTIGATIONS AND RESULTS During the scan survey, seven (7) locations exceeding the scan Investigation Level were identified. Seven (7) soil samples, 9528-0004-0191 through 025I, were collected at the locations to these scan readings. The investigation soil samples were analyzed by gamma spectroscopy at the HNP on site laboratory. The analysis met the required MDC. No data analysis results were a significant percentage of the Operational DCGL, with the maximum f-DCGL < 9% (see Table 9). Soil sample analysis results did not exceed the Investigation Level; therefore, no further actions or investigations were required.

9. REMEDIATION AND RESULTS Historically, no radiological remediation was performed in this survey unit prior to or as a result of the FSS. Excavation and trenching was performed in this survey unit for the purposes of removing manageable spoils and materials (e.g., concrete, asphalt, metal, etc.). The materials were surveyed for radiological contamination in accordance with health physics procedures. No materials were found to exceed the radiological release criteria for unrestricted use. Health Physics Department TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support ofFinalStatus Survey," has determined that remediation beyond that required to meet the release criteria to be unnecessary and that the remaining residual radioactivity in the soil was ALARA.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN There were no changes from the FSSP. There were no FSSP Addendums created.

11. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessnment," for completeness and consistency. The sampling design had adequate power as indicated by the Retrospective Power Curve. The Retrospective Power Curve was generated using COMPASS. The Sign Test was performed on the data and compared the results with the original assumptions of the DQOs. All soil sample results were less than the release criteria.

Therfore, 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).

The Cs-137 range of the data is about 4.2 standard deviations. The difference between the mean and the median was about 24% of the standard deviation. The Skew of the data was about 3.2. Excluding the highest Cs-137 result (6.60E-01 pCi/g) the range of the data is about 1.15. Statistical analyses reveal only one (1) positive outlier. This could be attributed to natural variations of environmental soil sampling with inductions from topographical and geological features. The total range of the sample results is consistent with concentrations of Cs-137 found in soil at offsite locations within the vicinity of the HNP. The maximum f-DCGLC,.13 7 was 21%.

Revision I 15 Revision 1 15

SOUTHEAST LANDFILL SURVEY UNIT 9535-0002 RELEASE RECORD The Co-60 range of data was about 3.9 standard deviations. The difference between the mean and the median was about 20% of the standard deviation. The Skew of the data was about 0.61. Statistical analyses reveal only one (1) positive outlier.

None of the samples exceeded 3% of the DCGLcO,60.

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

12. ANOMALIES Soil sample 9535-0002-06F yielded a positive identification of Sr-90 at 5% of the Base Case DCGL. The combined fraction of the Base Case DCGL including the Sr-90 results is <10%. The Sr-90 result did not impact the release of SU 9535-0002.

13. CONCLUSION Survey Unit 9535-0002 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 were 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 GroundwvaterDosefor PhaseII Release Areas of the FinalStatuts Survey Report ".
