FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9312-0009 (part of the former Radiologically Controlled Area (RCA)) is designated as Final Status Survey (FSS) Class 1 and has an area of approximately one thousand five hundred eleven (1,511) square meters of open land and is located approximately one thousand three hundred twenty six feet (1,326 ft) to the southeast of the site benchmark (Northing: 237370.20, Easting: 667394.57) used at Haddam Neck Plant (TINP) (see Attachment 1). The survey unit is bounded as follows: land Survey Unit 93 13-0000 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Unit 9312-0004, land Survey Unit 9312-0005, land Survey Unit 9312-0002 and land Survey Unit 9312-0010 to the west, land Survey Unit 9312-0010 to the south and land Survey Unit 9527-0005 to the east.

Survey Unit 9312-0009 includes all portions of the RCA that have the steep topography of the rock face and hillside. A smaller flat level gravel covered area is also located within the survey unit at the northwest boundary.

The reference coordinates associated with this survey unit are E0 13 through E0 15 by S064 through S071 (refer to ",HNP License Termination Plan" (LTP) Section 5.4.4).

The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10, "Survey Unit Classification."

The "ClassificationBasis Summary" conducted for Survey Unit 9312-0009 consisted of:.

a) A review of the I1OCFR5O.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historical Site Assessment Supplement, "

c) Historic and current survey records review, d) Visual inspections and a "walkdown."

A review of the "Initial and Supplemental CharacterizationReports" as well as the previous "ClassificationBasis Summaries" was performed. The source documents, the "Connecticut Yankee Haddam Neck Characterization Report" and "Initial Classification for Survey Areas at Connecticut Yankee", were incorporated by reference in LTP, Revision 0.

Revision 03 3

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD During plant operation, Survey Area 9312 was the location of significantly radiologically contaminated structures and systems, namely the reactor, the reactor systems and the Containment structure. Various radiologically contaminated structures that resided within or adjacent to Survey Unit 9312-0009 included the Yard Crane, the "Hot Tool Crib" and the Seavan Storage Shed. However a majority of the survey unit is comprised of a steep vertical rock face that runs north to south in the approximate center of the survey unit, roughly twenty (20) to twenity-five (25) feet high, with a depressed drainage trench along its base and a steep, grass-covered hillside along the summit, sloping from east to west.

A review of the historical documentation indicated a significant number of operational events that may have impacted Survey Unit 9312-0009. Operational events were considered to be spills and leakage from contaminated systems. These events would have had the most impact on the radiological condition of the underlying soil and bedrock prior to system and structural decontamination and demolition. Some of the major events are summarized as follows;

" In 1972, contamination was found on personnel that were breaking up rock on the east hillside for the relocation of a fire main. Contamination was discovered in the trench adjacent to the ion exchange cubicle. The area was decontaminated.

• Atmospheric releases from the stack have impacted the east hillside area, particularly a series of events that occurred in 1979. Stack discharges involving particulate activity occurred in February and December of 1979 as a result of the failure of the letdown degassifier and the actuation of the degassifier rupture disk.

The discharge line from the rupture disk was routed directly to the main discharge stack. Surveys performed following these events identified several areas of discrete contamination within the RCA, in the parking lot and along the east hillside.

• A resin overflow from a liner occurred in the vicinity of the resin pit that affected the east trench. Resin was removed from the pit and the sump and the affected areas were decontaminated.

• Recent radiological surveys resulted in the identification of contamination on the hillside east and southeast of the industrial area. It is not known if this contamination was the result of chronic release's or one or more episodic events.

Given the area where the contamination was found, potential sources include both plant main stack discharges and outdoor resin handling activities.

Major demolition and remediation activities began in 2002. All systems and components located inside this survey unit were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. All above grade structures were then demolished to grade.

Revision 04 4

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 93 12-0009 RELEASE RECORD Outside of the Containment shell, extensive soil remediation was performed in Survey Area 9312. A large excavation was created to the north of the Containment that was designated as Excavation #2. This excavation included the area in the vicinity of the Refueling Water Storage tank (RWST) and the Primary Auxiliary Building (PAB) corridor. A second large excavation, designated as Excavation #1 was located over the PAB footprint. A third excavation, designated as Excavation #3 was located in the area between the Containment Building and Spent Fuel Building (SFB). Soil was excavated and removed as adjacent structures were demolished.

This process continued until bedrock was exposed.

Subsurface structures and footings that remained following demolition and excavation include the Containment Mat, the Cable Vault wall, the Service Building east wall, a remnant of the PAB northwest wall, the Waste Disposal Building footing, the "B" Switchgear Building footing and miscellaneous fragments of footings and slabs on the bedrock. As with the Containment basement shell, all excavations were backfilled following the performance of a radiological assessment. No above grade structures currently reside within Survey Unit 9312-0009.

In Survey Area 9312, post-remediation soil samples were taken from the as-left surface soils under two (2) Survey and Sampling Work Plans, SSWP-06-08-000 and SSWP-06-12-00l. Thirty-five (35) post remediation surface soil samples were collected from the various locations within Survey Area 9312. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory.

Ten (10) of the thirty-five (35) post remediation samples collected were analyzed for the full suite of "Hard-to-Detect" (HTD) radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 3. Statistical quantities (mean, median and standard deviation) from the 2006 post-remediation survey conducted under SSWP-06-08-000 and SSWP-06-12-001 are provided in Table 1.

Table 1 - Basic Statistical Quantities for Cs-137 and Co-60 from the 2006 Post Remediation Survey Cs-137 Co-60 (pCilg) (Pci/g)

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD A review of this sample data showed Cs-137 and Co-60 to be the primary radionuclides of concern. Cs-137 was the predominant radionuclide over Co-60. No HTD radionuclides were positively identified in concentrations meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty).

While Sr-90 was not identified in the soil characterization results, it was decided to include Sr-90 as a radionuclide of concern for this survey unit as Sr-90 was prevalent in the soils prior to remediation. Therefore, all volumetric soil samples taken as part of the survey design for this survey unit were subjected to direct analysis for Sr-90.

In January of 2007, a FSS was designed and performed in this survey unit.

Systematic soil samples were taken in a triangular grid pattern from a random start location. This was combined with a scan survey of all accessible surfaces and investigative soil samples at locations exceeding the scan alarm set-point. Fifteen (15) systematic and thirty-three (33) investigative surface soil samples where taken in Survey Unit 9312-0009. Of the forty-eight (48) total samples taken, Cs-137 was positively identified (i.e. a result greater than two (2) standard deviations) in forty-five (45) soil samples, Co-60 was positively identified in twenty-seven (27) soil samples and Sr-90 was positively identified in twenty-six (26) soil samples. Other radionuclides were also positively identified by gamma spectroscopy and HTD analysis but at concentrations less than the screening criteria. Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates. In four (4) investigative soil samples, the concentration of Cs-137 exceeded the Operational DCGL of 4.75 pCi/g. A summary of the sample results are provided in Table 2.

Soil was removed from the four (4) identified locations that exhibited elevated activity greater than the Operational DCGL.

Revision 06 6

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Following remediation, twelve (12) post remediation surface soil samples were collected from the subject areas as well as the base of the rock-face. Soil samples were collected and analyzed by gamma spectroscopy by the on-site laboratory. No activity in excess of the Operational DCGL for Cs-137 and Co-60 was identified.

Based upon the sample results, the subject areas were considered to be successfully remediated.

The FSS Engineer performed a visual inspection and walk-down during March 2007 to assess the physical condition of the survey unit, evaluate access points, travel paths and identify potentially hazardous conditions.

This survey area is affected by existing and future groundwater (reference CY memo ISC 06-024) which will be a source of dose from residual radioactivity, as discussed in Section 3 under the Data Quality Objectives.

Based upon the identification of radioactive material above the Derived Concentration Guideline Levels (DCGLs), and the need for radiological remnediation, it was concluded that there was some probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class I (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5. 1-11, "Preparationof 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 indicate that residual activity within the survey unit does not exceed the release criteria.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9312-0009 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).

Revision 07 7

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 93 12-0009 RELEASE RECORD A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of DCGLs. The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations. Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soil (called Base Case Soil DCGL), existing groundwater radioactivity and future groundwater radioactivity that will be contributed by building basements and footings.

The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity.

Equation 1 shows the mathematical relationship between the three (3) components and the total dose.

Equation 1 HTotal =ITsoil +HExistingGw +/-LFutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr Total Effective Dose Equivalent (TEDE) from all three (3) components. The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for CY is nineteen (19) mremlyr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is bounded by two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mrem/yr TEDE.

Equation 2 19 mremlyrTotal =15 mremlyrs 1 il + 2 mremlyrExisting Gw+ 2 mrem/yrFutureGW The allowable dose for soil in this survey unit is fifteen (15) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in fifteen (15) mremlyr TEDE is designated as the Operational DCGL (DCGLop), and has been established for the radionuclides of concern as provided in Table 3.

The preferred result is the alpha spectroscopy's when both analyses are performed Revision 09 9

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Soil samples were collected as part of the previous FSS attempt in Survey Unit 9312-0009 for FSS. Cs-137, Co-60 and Sr-90 were the three (3) radionuclides reported in concentrations with the potential for exceeding the release criteria. The data from the previous FSS attempt was used for the design of FSS and are provided in Table 2.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparationof FinalStatus Survey Plans". The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The DQO process determined that Cs-137, Co-60 and Sr-90 would be the radionuclides of concern in Survey Unit 9312-0009 (refer to Section 3). Both the characterization survey and the previous FSS did not identify any other additional HTD radionuclides of concern for this survey unit. As Sr-90 concentrations were determined by direct analysis, surrogate DCGLs were not required as part of the survey design for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity' DCGLs". Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performance of this FSS would be evaluated to ensure adequate survey design.

As the survey unit is classified as a Class 1 surface soils area, and discrete, elevated areas of contamination was possible, the application of the Elevated Measurement Comparison (EMC) remained an option.

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- 13 7 as part of the sample set.

Revision 0 10

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 93 12-0009 RELEASE RECORD The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.73 to achieve a relative shift (A/aT) in the range of 1 and 3.

The resulting calculated relative shift was 1.29. 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 (I1OCFR2O, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified twenty-one (21) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information, the Characterization Survey data, the previous FSS data and the results of post-remediation sampling, the acquisition of additional judgmental surface soil samples from within this survey unit was deemed unnecessary.

The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 1 area.

Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 4.

Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis. Three (3) soil samples, or about 20% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RANDBETWEEN" function.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant"'and as provided in Table 3.

The LTP requires a minimum of 5% of the samples taken for non-parametric statistical testing be selected for QC evaluation. The implementation of 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.

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 93 12-0009. Grid lines, one (1) meter wide, were painted on the ground of the scan area. A background survey was performed around the survey unit and it was determined that, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 5,450 counts per minute (cpm) up to 17,900 cpm.

The large variance in background is caused by the presence of large deposits of exposed natural rock surfaces in the survey unit.

The scan area was established and scanned for elevated readings (see Attachment 2 for all scan results). Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with audio response. The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. Approximately 100% of the survey unit was scanned.

Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification. At each sample location, a one (1) meter radius circle was established around the sample flag or paint mark and was scanned for elevated radiation levels.

Twenty-one (21) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey"' and FSS design. Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples."

Three (3) samples (9312-0009-104F, 9312-0009-lIIOF and 9312-0009-118F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of two (2) samples (9312-0009-1 03F and 9312-0009-120) for "split sample" analysis.

6. SURVEY RESULTS All field survey activities were conducted between March 15, 2007 and April 23, 2007.

The sample locations identified in the ESS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 6 provides an overview of the scan results for sample measurement locations. Scan results are provided in Attachment 2.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the twenty one (2 1) samples collected for non-parametric statistical testing, the associated field splits and the fifteen (15) investigative samples using gamma spectroscopy. Gamma spectroscopy analysis was performed to the required MDCs.

Revision 0 16

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). However, Cs-137 and Co-60 were the only two gamma-emitting radionuclides reported in any appreciable concentration.

Cs-137 was positively identified in nineteen (19) and Co-60 was identified in eight (8) of the twenty-one (2 1) samples collected for non-parametric statistical testing. In sample 9312-0009-106F, Cs-137 was present at a concentration exceeding the Operational DCGL of 4.75 pCi/g. In sample number 9312-0009-1 19F, the sum of the concentrations for the radionuclides of concern exceeded the unity value of one (1).

A summary of the twenty-one (21) samples collected for non-parametric statistical testing results is provided in Table 8.

In addition to Sr-90, the off-site laboratory also processed, as required by the sample plan, three (3) samples for the full suite of HTD radionuclides as specified in LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 3. The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses performed met the required minimum MDC. No additional HTD radionuclides were positively identified (i.e., a result greater than two (2) standard deviations uncertainty).

The "sum-of-fractions" or "unity rule" is the mathematical test used to evaluate compliance with radiological criteria for license termination when more than one radionuclide has been determined to be potentially present. The combination of the fractions of each detected radionuclide against their respective Operational DCGL must be less than or equal to one (1).

The unity rule is:

Equation 3 C, + C2+ <1 DCGLI DCGL 2 DCGL,,

Where: QC concentration of radionuclide n and DCGLn = DCGL of radionuclide n.

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Cs-137, Co-60 and Sr-90 were all positively identified. The investigative samples taken from sample locations 93 12-0009-127-I, 93 12-0009-132-I, 9312-0009-133-1, 9312-0009-135-I and 9312-0009-136-I exceeded the Operational DCGL of 4.75 pCi/g for Cs-137 and the investigative sample taken from sample location 9312-0009-137-I contained sufficient concentrations of Cs-137, Co-60 and Sr-90 to exceed the "unity rule" parameter of one (1). The results of the investigative samples were displayed on a posting plot (see Attachment 1) to illustrate the relative size and orientation of the areas exhibiting elevated activity.

At sample location 93 12-0009-127-I, the surface is predominantly composed of natural rock outcroppings at the base of the vertical rock face. Surface scanning indicated elevated activity in a crack in the rock face at this location in excess of the action level. Subsequently, a surface soil sample was collected from the crack that was composed of essentially all the soil that was present in the crack. The soil at the base of the rock face under the crack was scanned as well and no measurements in excess of the action level were observed. The analysis of the soil sample taken from the rock crack indicated the presence of Cs-137 at a concentration of 25.5 pCi/g or five (5) times the Operational DCGL for Cs-137. The action for the identification of residual radioactivity concentrations of this magnitude would normally prompt additional remediation. However, as the investigative soil sample that was taken had removed all of the soil, there was no volumetric material remaining inside the rock crack to remediate. Additional surface scans were performed to confirm that no additional elevated scan measurements in excess of the action level remained.

Subsequently, the sample result for survey location 9312-0009-127-1 was not included in the EMC calculation.

Following a review of the posting plot, it was subsequently determined that three (3) distinct areas of elevated activity were present. In addition, only one of the areas was adequately bounded by the statistical grid and investigation soil samples. It was subsequently determined that eight (8) additional surface soil samples would be necessary to adequately bound the two (2) remaining areas of elevated activity identified at sample locations 9312-0009-1 06F and 9312-0009-137-I.

Additional bounding sample locations were identified in Addendum 2 to the Final Status Survey Plan. Four (4) additional samples were taken at a distance of one-half (V2) meter from each of the designated sample locations, oriented relative to the compass points of north, east, south and west. The sample results and the results of the unity rule calculation for the radionuclides of concern in the bounding sample population are provided in Table 13.

Cs-137 was positively identified in six (6), Co-60 was positively identified in four (4) and Sr-90 was positively identified in two (2) of the eight (8) additional samples taken for area bounding. One (1) of the bounding surface soil samples contained sufficient concentration of Sr-90 to exceed the Operational DCGL of 0.93 pCi/g for Sr-90 by a factor of three (3). The results of the additional bounding samples were displayed on the posting plot to further refine the relative size and orientation of the areas exhibiting elevated activity.

Following a review of the posting plot, it was determined that one (1) additional surface soil sample would be necessary to further define the boundary of one of the previously identified areas of elevated activity. The sample location was identified in Addendum 3 to the Final Status Survey Plan. One (1) additional sample was taken at a distance of one-half (V2) meter to the west of sample location 9312-0009-141-I, where the elevated Sr-90 concentration was observed. The sample results and the results of the unity rule calculation for the radionuclides of concern in the additional bounding sample are provided in Table 14.

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Cs-137 and Co-60 was positively identified at concentrations less that their respective Operational DCGL. Sr-90 was not positively identified in this sample. The results of the additional bounding sample was displayed on the posting plot to further refine the relative size and orientation of the one remaining unbounded area. It was concluded that the area of elevated activity was adequately bounded and no additional bounding sample were deemed necessary.

The Elevated Measurement Comparison (EMC) protocol was applied to the three (3) identified areas of elevated activity in accordance with LTP Section 5.8.3 and 5.4.7.4.

The values used for the area factor for each area was determined from the area bounded by the adjacent samples or by the area bounded by additional samples at or below the DCGLOP.

Two (2) of the three (3) elevated areas are located along the top of the twenty (20) foot high vertical rock face. The other area, identified at sample location 9312-0009-1 06F, is located in the drainage trench at the base of the vertical rock face in the northern portion.of the survey unit. This area is designated as Elevated Area

1. 1. The second area, designated as Elevated Area #2, is located at the summit of the rock face, toward the north end of the survey unit, approximately adjacent to land Survey Unit 9312-0005 and the former location of the Ion Exchange structure.

Elevated Area #1 and Elevated Area #2 were bounded by the additional nine (9) surface samples taken around each identified area at a distance of one (1) and one-half

('/2) meters respectively. The approximate area of Elevated Area #1 is four (4) square meters and the approximate area of Elevated Area #2 is one (1) square meter. The third area, designated as Elevated Area #3 is located toward the south end of the rock face along a notch in the hillside adjacent to where the Primary Water Storage Tank was located. The "inquiry" function included with the AutoCAD-LT computer program was used to establish the size of the larger elevated area in the southern portion of the survey in square meters. The approximate area of elevated activity is seventy six (76) square meters.

Area Factors for each radionuclide corresponding to the size of the elevated area was selected from Table 5-5, Area Factorfor the Resident Farmer Scenario, in Section 5.4.7.4 of the LTP. The Area Factors selected are provided in Table 15.

As this value is less than one (1), this survey unit passes the unity EMC test.

9. REMEDIATION AND RESULTS Radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit. Soils exhibiting residual radioactivity in excess of Operational DCGLs were removed along the base of the vertical rock face, from ledges on the rock face and from four (4) different locations along the summit of the rock face.

Excavations along the base of the rock face were characterized and backfilled prior to performing FSS. Areas subjected to remediation that were located on or on top of the rock face were remediated to bedrock. The results of post remediation samples taken in each of these areas following remediation were below the Operational DCGL for Cs-137 provided in Table 3.

Revision 0 27

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of FinalStatus Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN A soil sample from location 9312-0009-11 8F was unobtainable due to the presence of rock and lack of volumetric soil within a three (3) meter radius of the sample location.

Sample location 9312-0009-126F was added under an addendum to the FSS plan as a replacement sample location. Sample location 9312-0009-1 26F was determined randomly using VSP.

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. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.

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 1.

The preliminary data review consisted of calculating basic statistical quantities (e.g.,

mean, median, standard deviation). The mean and median values are well below the Operational DCGL. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs. The basic statistical quantities for the statistical sample population are provided below in Table 17.

Table 17 - Basic Statistical Quantities for Cs-137, Co-60, and Sr-90 from the Final Status Survey Cs-137 Co-60 Sr-90 pCilg pCilg pCilg DCGL0 ,P: 4.75E+00 2.29E+00 9.30E-01 Minimum Value: 6.l1OE-03 -1.13E-02 -2.07E-02 Maximum Value: 5.55E+00 4.43E-01 4.5 1lE-02 Mean: 9.43E-01 4.85E-02 7.75E-03 Median: 1.57E-01 9.9 1E-03 5.42E-03 Standard Deviation: 1.50E+00 L.OOE-01 1.95E-02 Revision 0 28

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 93 12-0009 RELEASE RECORD The range of the data, approximately three (3) to four (4) standard deviations for all three (3) radionuclides, was not a particularly large variation. The two (2) identified areas of elevated activity caused the data set to skew positively as represented by a calculated skew of 2.29 for Cs-137 and 3.39 for Co-60. The calculated skew for Sr-90 is 0.42. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. All data, assessments, and graphical representations are provided in Attachment 4.

12. ANOMALIES An investigative soil sample taken from a crack in the vertical rock face indicated a Cs-137 concentration of 25.5 pCi/g. The process of taking the investigative soil sample removed all volumetric soil from the crack, essentially performing remediation. Due to the fact that the soil exhibiting the elevated activity was removed and is no longer present in the survey unit, the results of the elevated measurement observed at investigative sample location 9312-0009-127-I was not included as part of the EMC calculation.

13. CONCLUSION Survey Unit 9312-0009 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

An EMC calculation was performed for three (3) identified areas of elevated activity in accordance with LTP Section 5.8.3 and Equation 4 of this report. The results indicated that the area was less than unity. No further action is warranted. See Tables 13 through 16 of this report for specific information with regard to the EMC calculation.

All identified radionuclides of concern were used for statistical testing to determine the adequacy of the survey unit for FSS.

The sample data passed the Sign Test. The null hypothesis was rejected with adequate power. The survey unit is properly designated as Class 1.

The dose contribution from soil is 3.42 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) mremlyr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mremlyr TEDE.

Revision 0 229

FORMER RADIOLOGICALLY CONTROLLED AREA EAST TRENCH NORTH SURVEY UNIT 9312-0009 RELEASE RECORD The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity will not exceed 7.42 mrem/yr TEDE. Therefore, Survey Unit 93 12-0009 is acceptable for unrestricted release.

Data Review Qualifier Definitions Qualifier Explanation

• A quality control analyte recovery is outside of specified acceptance criteria

• • Analyte is a surrogate compound

• Result is less than value reported

• Result is greater than value reported RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL A The TIC is a suspected aldol-condensation product B Target analyte was detected in the associated blank B Metals-Either presence of analyte detected in the associated blank, or MDL/IDL < sample value < PQL BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample d 5-day BOD-The 2:1 depletion requirement was not met for this sample E Organics-Concentration of the target analyte exceeds the instrument calibration range E Metals-%difference of sample and SD is >10%. Sample concentration must meet flagging criteria H Analytical holding time was exceeded h Preparation or preservation holding time was exceeded J Value is estimated N Metals-The Matrix spike sample recovery is not within specified control limits N Organics-Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC) . Quantitation is based on nearest internal standard response factor N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Anslyte concentration is not detected above the reporting limit DI Gamma Spectroscopy-Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound Z Paint Filter Test-Particulates passed through the filter, however no free liquids were observed.

The Qualifiers in this report are defined as follows:

• • Analyte is a surrogate compound

• Result is less than value reported

• Result is greater than value reported A The TIC is a suspected aldol-condensation product B For General Chemistry and Organic analysis the target analyte was detected in the associated blank.

BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample H Analytical holding time was exceeded J Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the detection limit R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

UI Gamma Spectroscopy--Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound A RPD of sample and duplicate evaluated using +/-RL.

• • Indicates analyte is a surrogate compound.

^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.

• • Analyte is a surrogate compound

• Result is less than value reported

• Result is greater than value reported A The TIC is a suspected aldol-condensation product B For General Chemistry and Organic analysis the target analyte was detected in the associated blank.

BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GClMS analysis D Results are reported from a diluted aliquot of the sample H Analytical holding time was exceeded J Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the detection limit R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

UI Gamma Spectroscopy--Uncertain identification

• Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier

• QC Samples were not spiked with this compound A RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

• • Indicates analyte is a surrogate compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
