FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9312-0005 (inside the formner Radiologically Controlled Area (RCA)) is designated as Final Status Survey (FSS) Class 1 and has an area of approximately one thousand four hundred sixty (1,460) square meters of open land and is located approximately one thousand three hundred fifty nine feet (1,359 ft) to the southeast of the site benchmark (Northing: 237370.20, Easting: 667394.57) used at Haddam Neck Plant (IJNP) (see Attachment 1). The survey unit is bounded as follows: land Survey Unit 9312-0004 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Unit 9312-0006 to the west, land Survey Unit 93 12-0001 and land Survey Unit 93 12-0002 to the south and land Survey Unit 93 12-0009 to the east. As a result of demolition and remediation activities, the area topography is mostly flat and de-vegetated. The survey unit has a moderate slope running from east to west.

The reference coordinates associated with this survey unit are EO 11I through EO013 by S064 through S066 (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 9312-0005 consisted of:

a) A review of the IOCFR5O.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 TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD During plant operation, Survey Unit 9312-0005 was the location of several significant reactor support structures and systems, primarily consisting of a grouping of liquid storage tanks referred to as- the "Tank Farmn" and the Spent Resin Facility.

The Tank Farmn was an asphalt covered area located to the northeast of the former location of the Containment structure where the Refueling Water Storage Tank (RWST), the Waste Test Tanks A & B, the Aerated Drains Holdup Tank (ADHUT),

the Borated Waste Storage Tank (BWST) and the Recycle Test Tanks (RTT's) were located. Rupture-containment dikes were constructed around the bases of these tanks.

In addition, the area also contained sub-grade covered and shielded pipe trenches that housed subsurface piping and conduit associated with the tanks and other adjacent support systems. All of these tanks and systems had contained radioactive liquids over their history and were highly contaminated. Contamination levels in several of the systems were high enough to create high radiation areas in their vicinity.

The Resin Slurry and Ion Exchange Area included the "Ion Exchange Structure", the "Spent Resin Facility" and "Spent Resin Storage Facility". This area was located in the yard on the east side of the Tank Farmn. All surfaces within these areas were contaminated during facility operation. On multiple occasions, there was documentation of the loss of contamination control during filter change-outs and resin processing activities, resulting in the spread of alpha, beta and gamma contamination.

Samples taken in 1980 during the installation of modifications indicated the presence of significant concentrations of Cs- 13 7 and Co-60 in the area of the original concrete support pad and the soil around it.

A review of the historical documentation indicated a significant number of operational events that may have impacted Survey Unit 9312-0005. 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 subsurface structures and footers; and the underlying soil and bedrock prior to system and structural decontamination and demolition. Some of the major events are summarized as follows;

" Diaphragm rupture, valve failure and gasket leakage from components associated with the Refueling Water Storage Tank (RWST) resulted in documented spills of radioactive liquid into the alleyway between the Containment structure and the Primary Auxiliary Building (PAB) in November 1973, February 1976, December 1976, February 1978 and January 1979.

" A frozen degassifier line in February 1979 caused the rupture of the diaphragm disc and led to leakage of reactor cavity water into the main stack drain and subsequently onto the surrounding area in the PAB alleyway. The report estimated a release of mixed fission and activation products onto the ground and the storm drains.

Revision 04 4

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD

• A series of events in September 1979 resulted in the release of steam generator contents into the stack. The steam condensed in the stack ductwork and subsequently leaked 50 to 75 gallons of contaminated water onto the alleyway.

All of the liquid was removed and the area was decontaminated.

" The degassifier rupture diaphragm actuated in December 1979 and vented gaseous contents up the stack and liquid conltents near the base of the stack. The impacted areas and systems were storm sewers, roof drain lines, stack, stack duct and drain lines and the PAB roof. All impacted areas were remediated.

• In September of 1981 and again in October of 1981, contaminated water overflowed from the RWST hatch onto the nearby ground due to a valve misalignment and the activation of the thermo siphon heater.

" Contaminated water from RWST cleanup hoses leaked onto the alleyway in April 1990. The area was decontaminated and released.

" In September 1990 and July 1994, cracks in the welds located in the base of the RWST led to leakage of contaminated water onto the tank pedestal.

" An improperly fabricated flange led to water leakage from the RWST in November 1991 and January 1992.

" During a rainstorm in August 1997, an overflow of water from the RWST catch basin area to an uncontrolled sand area was observed. Analysis of the water indicated H-3, Co-60 and Cs-137. The Condition Report identified the catch basin overflow as a potential source of historical tritium contamination of the yard drains and external containment mat sump.

" In June 1998, leakages from the RWST floor plates and manway port flanged joints were observed. The water accumulated around the tank foundation and trough areas on the western side of the tank. Analysis of water samples from both leaking areas identified the source of both leakages as the RWST.

" An HP survey in October 1998 revealed loose contamination at levels inside the catch containment at the base of the RWST.

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.

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 RWST and the 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 Revision 05 5

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD 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 remynant 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 93 12-0005.

In Survey Area 9312, post-remediation soil samples were taken from the as-left surface soils under two (2) Survey and Sampling Work Plans, SSWPT-06-08-000 and SSWP-06-12-001. 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.

Minimum Value: 1.32E-02 -5.OOE-02 Maximum Value: 1.70E+/-00 1.43E+/-00 Mean: 2.3 8E-0 I 1.08E-01 Median: 1.65E-01 1.46E-02 Standard Deviation:T 3. 1OE-0 I 2.76E-0 I A review of this sample data shows Cs-137 and Co-60 to be the primary radionuclides of concern, with both isotopes reported at fairly low concentrations.

The sample population as a whole was evaluated to assess the distribution of the detected radionuclides. The radionuclide distribution percentage for each sample in the population was calculated by dividing the concentration of each detected radionuclide by the total activity concentration in the sample, expressing the abundance of the specific nuclide in the sample compared against the total activity.

The mean radionuclide distribution was then calculated by taking the average of the individual sample distribution fractions. The results are provided in Table 2.

Revision 06 6

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD Cs-137 0.689 Co-60 0.311 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). 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. 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.

The FSS Engineer performed a visual inspection and walk-down during January 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 remediation, 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" (MARS SIM). 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.

Revision 07 7

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD 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 9312-0005 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).

A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of 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 Hiotai -H Soil +/-HExistingGW +/-HFutureGW 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) mremlyr TEDE.

The concentration of residual radioactivity resulting in fifteen (15) mremi/yr TEDE is designated as the Operational DCGL (DCGLOp), and has been established for the radionuclides of concern as provided in Table 3.

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD Another important facet of the DQO process Is to identify the radionuclides of concern and determnine the concentration variability. Soil samples were collected in 2006 to establish the radiological condition of Survey Unit 9312-0005 for FSS.

Cs-137 and Co-60 were the two (2) gamma emitting radionuclides reported in concentrations with the potential for exceeding the release criteria. Sr-90 was included as a radionuclide of concern due to it's prevalence in the soil prior to remediation. The characterization data were used for the survey design and are provided in Table 1.

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 Final Status 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 9312-0005 (refer to Section 3). The characterization survey did not include any other additional HTD radionuclides of concern for this survey unit. As Sr-90 concentrations were determnined 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 I 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-I137 as part of the sample set.

Revision 0 II

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 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/cs) in the range of 1 and 3.

The resulting adjusted relative shift was 2.0. 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 MARS SIM in support of the decommissioning license termination rule (I OCFR2O, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified, fifteen (15) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information and Characterization Survey data, four additional (4) judgmental samples were taken in this survey area. One (1) judgmental sample was taken adjacent to the former location of the Waste Test Tanks, one (1) judgmental sample was taken adjacent to the former location of the RWST, one (1) judgmental sample was taken adjacent to the former location of the BWST and one (1) judgmental sample was taken adjacent to the former location of the ADHUT.

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.

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 Su~rvey," included the collection of one (1) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function.

The LTP specifies a required scanning coverage of 100% for outdoor Class 1 areas.

For this Class 1 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8. Table 5 provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under a Final Status Survey Plan (FSSP). The FSSP package included a*detailed survey plan, 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.

A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 93 12-0005. 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 5,640 counts per minute (cpm) up to 12,500 cpm.

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD 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 was scanned for elevated radiation levels.

Nineteen (19) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (H-NP) 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 (9312-0005-006F, 9312-0005-014F and 9312-0005-015F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of one (1) sample (93 12-0005-01lIF) for "split sample" analysis.

6. SURVEY RESULTS All field survey activities were conducted between March 1, 2007 and March 14, 2007.

The sample locations identified in the FSS 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 fifteen (15) samples collected for non-parametric statistical testing, the associated field splits and the four (4) judgmental samples using gamma spectroscopy. Gamma spectroscopy analysis was performed to the required MDCs. 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 four (4) and Co-60 was identified in two (2) of the fifteen (15) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels slightly lower than expected environmental levels for Cs-137 within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 8.

Subsequently, all samples were subjected to analysis by gas proportional counting for Sr-90. All analyses met the required minimum MDC.

Sr-90 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in three (3) of the fifteen (15) samples collected for non-parametric statistical testing. The results of the Sr-90 analysis for the statistical sample population are provided below in Table 9.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method.

Tc-99 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in one of the three (3) samples analyzed for HTD radionuclides. As previously stated in Section 4 of this report, the criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates.

Revision 0 19

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 93 12-0005 RELEASE RECORD For Tc-99, the Operational DCGL is 7.60 pCi/g to achieve a TEDE of fifteen (15) mrem/yr. The analytical results for Tc-99 in sample 93 12-0005-014F equated to 16.20 pCi/g or 213% of the Operational DCGL. Subsequently, Tc-99 was added as a radionuclide of concern and all soil samples for this survey unit were subjected to additional analysis for the presence of Tc-99. No other HTD radionuclides were detected. The results of the Tc-99 analysis for the statistical sample population are provided below in Table 10.

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 9312-0005 RELEASE RECORD The analytical results for the soil sample taken from location 9312-0005-014F indicate residual radioactive material present in concentrations exceeding the individual Operational DCGLs for Co-60 and Tc-99 and exceeding the unity value of one (1). Additional samples were taken to bound the discrete area of elevated activity. The results of the bounding samples and Elevated Measurement Comparison (EMC) are presented in Section 8 of this report.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. One sample location was selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey". Cs-137 was not detected in sufficient quantity in the field split results at location 93 12-0005-01 IF to evaluate in accordance with procedure. Evaluation using the reported results for naturally occurring K-40 resulted in acceptable agreement between the field-split results at this location. The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachments 3 and 4 for data and data quality analysis results

8. INVESTIGATIONS AND RESULTS Following a review of the analytical results for the designed sample population, it was determined that four (4) additional surface soil samples would be necessary to adequately bound the area of elevated activity identified by sample 9312-0005-01 4F.

Bounding sample locations were identified in Addendum 1 to the Final Status Survey Plan. The four (4) bounding samples were taken at a distance of one (1) meter from the location of sample number 9312-0005-014F, 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 12 below.

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 9312-0005 RELEASE RECORD Cs-137, Co-60 and Sr-90 were not positively identified in any of the bounding samples. Tc-99 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in three (3) of the four (4) samples, but at concentrations meeting the criteria for de-selection (i.e. a concentration that is less than 5% of the Operational DCGL for an individual radionuclide). Subsequently, the area of elevated activity was deemed to be adequately bounded.

The Elevated Measurement Comparison (EMC) protocol was applied to the area of elevated activity in accordance with LTP Section 5.8.3 and 5.4.7.4. The value used for the area factor for each area was determined from the area bounded by the adjacent samples at or below the DCGLOP. Due to the fact that the bounding samples were taken at a distance of one (1) meter in each direction from the sample location identified as elevated, the elevated area size was determined to be four (4) 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 13.

Cs-137 8.98 Co-60 4.22 Sr-90 314 Tc-99 276 Using the Area Factors presented in Table 13 and the results of the soil samples, the following EMC calculation was deduced; Equation 4 (5 l'evafedl J + elevatedi DCGLOP (A reaFactor)xD CGLOP + (AreaFactor)XDCGLOP where:

J= average concentration outside of the elevated area Celevated 1,2, i= average concentration inside elevated area i The average concentration of the area within the survey unit outside of the elevated areas (6) was calculated by taking the average radionuclide concentration from all surface soil samples and subtracting the radionuclide concentration average from the elevated area. This information is presented in Table 14.

9. REMEDIATION AND RESULTS Radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to FSS. All excavations were characterized and backfilled with "clean" fill prior to performing FSS. In the area where remediation occurred, the ground area is comprised of barren dirt with no vegetation, and the soils have been graded relatively flat to the corresponding elevation of the adjacent survey units.

The results for Cs-137 following remediation were well below the Operational DCGL provided in Table 3. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

Revision 0 224

FORMER RADIOLOGICALLY CONTROLLED AREA TANK FARM SURVEY UNIT 9312-0005 RELEASE RECORD

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN An addendum to the FSS plan was initiated on March 14, 2006 to implement the acquisition of additional soil samples necessary to adequately bound an area of elevated activity identified by the initial sample results.

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 16.

DCGL0 ,P: 4.75E+/-00 2.29E+/-00 9.30E-01 7.60E+00 Minimum Value: -2.47E-02 -1.16E-02 -1.36E-02 -2.41 E-01I Maximum Value: 2.37E+/-00 2.6 1E+00 3.99E-02 1.62E+/-01 Mean: 1.65E-01 1.75E-01 1.21E-02 1.13E+/-00 Median: 8.59E-03 2.48E-03 1.36E-02 8.99E-02 Standard Deviation: 6. 1OE-0 I 6.74E-0 1 1.60E-02 4.1 7E+/-00 The range of the data, about four (4) standard deviations for all four (4) radionuclides, was not a particularly large variation. The single area of elevated activity represented by sample location 9312-0005-014F caused the data set to skew positively as represented by a calculated skew of 3.87 for Cs-137, Co-60 and Tc-99. The calculated skew for Sr-90 is -0.15. 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 Analysis of the surface soil sample taken from location 9312-0005-014F indicated the presence of Co-60 at a concentration greater than the Operational DCGL for Co-60 and Tc-99 at a concentration three (3) times the Operational DCGL for Tc-99. Scan surveys of the area and subsequent bounding soil samples indicate that no additional discrete areas exhibiting elevated activity were present.

13. CONCLUSION Survey Unit 93 12-0005 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 an area 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 determnine 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 4.11 mremlyr 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) mrem/yr TEDE.

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 8.11 mrem/yr TEDE. Therefore, Survey Unit 93 12-0005 is acceptable for unrestricted release.

• 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 e5X 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-Concentrat ion 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 Analyte 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. Concentrations are <5X the RL h Preparation or preservation holding time was exceeded 33

• • 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.
