The survey unit is bounded by land Survey Unit 9530-0004.

The survey unit is relatively level open space in the middle of the peninsula.

The restoration of the peninsula for FSS has removed most surface interference in the survey unit;however, there are some trees and bushes remaining in the area.The reference coordinates associated with this survey unit are E013 through E018 by S095 through S109 (refer to 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 historical information, scoping analyses and characterization results provided sufficient data to designate Survey Unit 9530-0001 as Class 2 in August 2006.The "Classification Basis Summary" conducted for Survey Unit 9530-0001 consisted of: a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site.Assessment Supplement, " c) Historic and current survey records review, d) Visual inspections and a "walkdown." A review of the 1OCFR50.75(g)(1) database report identified two documents associated with this survey unit.a) Event PIR 80-37: Contamination was documented to be present in an area outside the restricted area. Small areas of low-level contamination were found on the facility grounds through a routine survey in a normally non-radioactive area.b) Event PIR 89-35: Contamination was identified in the 115 kV switchyard moat (Structure 111, refer to Connecticut Yankee (CY)Drawing SK-16112-10032 sheet 2. The source of the contamination was the discharge of approximately fifty (50) gallons of radioactive liquid using an unmonitored, unmarked drain line in the Spent Fuel Building.

Once identified, decontamination was performed in the Revision 0 3 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD switchyard moat and an outfall area outside the Radiologically Controlled Area (RCA). However, a plant survey performed on 2/28/89 shows that some of the radioactive material was deposited along the unpaved road in this survey unit. The survey also documents that the area was excavated and surveyed when the condition was identified.

The survey documents that count rates using portable beta detection instrumentation were less then one hundred corrected counts per minute above background (100 ccpm).A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" provided no additional information pertinent to classification.

The survey unit had undergone FSS in the fall of 2004 and release records documenting the satisfactory completion of the FSS objectives were in preparation.

In 2006, utilities were being removed as part of the decommissioning effort on the Upper Peninsula.

Construction debris including Asbestos Containing Material (ACM) was identified and remediated.

In addition to the ACM, several objects were also identified that had detectable radioactivity.

Two pieces of angle iron were located in a water utility trench in adjacent Survey Unit 9530-0004.

Most of the work involved two areas adjacent to Survey Unit 9530-0001.

Some of the excavated spoils from these areas were temporarily stored in Survey Unit 9530-0001 during the investigation.

Based on the potential to change the final radiological status of the survey unit, another FSS was considered prudent to define the as-left radiological condition.

Soil samples were collected in 2006 to establish the radiological condition of the surface and subsurface area following removal of soil. Cs-137 was the only gamma emitting radionuclide reported in concentrations with the potential for exceeding the screening criteria.

Therefore, the previous FSS data and statistical parameters were used for the survey design. Statistical quantities from the previous FSS survey are provided in Table 1.Table I -Baic nities fon tepo FSSSurvey Minimum Observed Concentration (pCi/g): 6.39E-02 Maximum Observed Concentration (pCi/g): 3.15E-01 Mean (pCi/g): 1.61E-01 Median (pCi/g): 1.15E-01 Standard Deviation (pCi/g): 9.16E-02 Revision 0 4 Revision 0 4 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD The FSS Engineer performed a visual inspection and walk-down during August 2006 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

This survey area is affected by existing 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 historical information and the results of radiological surveys performed during characterization, it was concluded that there was a low probability for residual radioactivity to be present in this survey unit in concentrations greater than the Operational Derived Concentration Guideline Levels (DCGLs) justifying a final survey unit classification of Class 2 (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, "Preparation of Final Status Survey Plan, " and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM).

A summary of the main features of the DQO process are provided herein.The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis.

Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition.

The baseline condition is technically known as the null hypothesis.

Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection.

In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria.

Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria.

Therefore, the survey unit does satisfy the primary objective of the FSS plan.The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9530-0001 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 Revision 0 5 Revision 0 5 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 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 =Hsoil +HExistingGW

+-HFutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr 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) mrem/yr 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 not considered impacted by future groundwater radioactive contamination, as there are no buried concrete foundations or footings 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, therefore, zero (0) mrem/yr TEDE.Equation 2 19 mrem/yrTotal

= 17 mrem/yrsoil

+ 2 mrem/yrExisting GW+ 0 mrem/yrFutureGW The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.Revision 0 6 Revision 0 6 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD C-14 5.66E+00 3.85E+00 2.26E-01 Mn-54 1.74E+01 1.18E+O1 6.96E-01 Fe-55 2.74E+04 1.86E+04 1.1 OE+03 Co-60 3.81 E+00 2.59E+00 1.52E-01 Ni-63 7.23E+02 4.92E+02 2.89E+O1 Sr-90 1.55E+00 1.05E+00 6.20E-02 Nb-94 7.12E+00 4.84E+00 2.85E-01 Tc-99 1.26E+01 8.57E+00 5.04E-01 Ag-108m 7.14E+00 4.86E+00 2.86E-01 Cs-134 4.67E+00 3.18E+00 1.87E-01 Cs-137 7.91E+00 5.38E+00 3.16E-01 Eu- 152 1.01E+01 6.87E+00 4.04E-0 1 Eu-154 9.29E+00 6.32E+00 3.72E-01 Eu-155 3.92E+02 2.67E+02 1.57E+01 Pu-238 2.96E+0 1 2.01 E+O1 1.1 8E+00 Pu-239/240 2.67E+01 1.82E+01 1.07E+00 Pu-241 8.70E+02 5.92E+02 3.48E+O 1 Am-241 (5) 2.58E+01 1.75E+01 1.03E+00 Cm-243/244 2.90E+01 1.74E+01 1.16E+00 (1) Bold indicates those radionuclides considered to be Hard-to-Detect (HTD)(2) The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to 25 mrem/yr TEDE (3) The Operational DCGL is equivalent to 17 mrem/yr TEDE (4) The required MDC is equivalent to I mrem/yr TEDE (5) Americium-241 can be analyzed by gamma and alpha spectroscopy and is considered to be Easy to Detect (ETD); the preferred result is the alpha spectroscopy's when both analyses are performed Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability.

Soil samples were collected in 2006 to establish the radiological condition of the surface and subsurface area following removal of soil. Cs-137 was the only gamma emitting radionuclide reported in concentrations with the potential for exceeding the screening criteria.

The previous FSS data and statistical parameters 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 Revision 0 7 Revision 0 7 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 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, "Preparation of 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 would be the radionuclide of concern in survey unit 9530-0001 (refer to Section 3). Other radionuclides identified during this FSS would be evaluated to ensure adequate survey design.Surrogate DCGLs were not required for this survey unit based the previous FSS of this survey unit and via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". 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.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 2 area and discrete, elevated areas of contamination were not expected.The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation.

This approach was conservative since it included background Cs-137 as part of the sample set.The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 5.26 to maintain the relative shift (A/a) 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 MARSSIM in support of the decommissioning license termination rule (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.Revision 0 8 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD The survey design specified fifteen (15) surface soil samples for non-parametric statistical testing and two (2) samples at biased locations.

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 2 area.Judgmental sampling was included as a feature of this survey design to account for any anomalies potentially identified in the field.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 3.Table3 -Samp!le Measurement Locations with Associated GPS Coordinates1 Desigmaion i Northing Ea4stinp 9530-0001-OOIF 235541.75 670285.43 9530-0001-002F 235541.75 670353.87 9530-0001-003F 235541.75 670422.31 9530-0001-004F 235541.75 670490.75 9530-0001-005F 235482.48 670388.09 9530-0001-006F 235482.48 670456.53 9530-0001-007F 235482.48 670524.97 9530-0001-008F 235482.48 670593.41 9530-0001-009F 235423.21 670490.75 9530-0001-01OF 235423.21 670559.19 9530-0001-01 IF 235423.21 670627.63 9530-0001-012F 235423.21 670696.07 9530-0001-013F 235423.21 670764.51 9530-0001-014F 235363.93 670661.85 9530-0001-015F 235363.93 670730.29 9530-0001-016F 235442.18 670580.76 9530-0001-017F 235463.77 670617.68 Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis.

Two (2) soil samples, or about 10% of the number of samples that would be used for non-parametric statistical testing were Revision 0 9 Revision 0 9 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 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 2.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.

The number of quality control soil samples was about 10% of fifteen (15) samples.The LTP specifies that scanning will be performed along with a combination of systematic and judgmental measurements (samples) for a Class 2 land area and should cover between 10% to 100% of the area. The fraction of scanning coverage was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS.Based on the historical site assessment, the characterization data available, and the use of the survey unit to store spoils from remediation, it was determined that scanning was required in three (3) separate areas. The total surface area to be scanned was approximately 15% of the survey unit. A map of the scan grid locations is provided in Attachment 1.For this Class 2 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0038.

The WP&IR package included a detailed FSS 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.Three (3) scan areas were established that constituted approximately 15% of the surface area of Survey Unit 9530-0001.

Grid lines, one meter wide, were painted on the ground of each of the three (3) scan areas. A background survey was performed around the survey unit and it was determined that, using a Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 6,200 counts per minute (cpm) up to 8,100 cpm.The scan areas were established and each area was 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 15% 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 around the sample flag or paint mark was scanned for elevated radiation levels.Fifteen (15) 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." Revision 0 I1I Revision 0 11 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD Two (2) samples (9530-0001-003F and 9530-0001-008F) were randomly selected for HTD radionuclide analysis.The implementation of survey specific quality control measures included the collection of two (2) samples (9530-0001-006F and 9530-0001-014F) for "split sample" analysis.6. SURVEY RESULTS All field survey activities were conducted between September 8, 2006 and September 15, 2006.The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan results for sample measurement locations.

The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field splits, the two (2) biased samples, and the one (1) confirmatory sample 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 standard deviations uncertainty).

Revision 0 13 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD Cs-137 was identified in fourteen (14) of the fifteen (15) samples collected for non-parametric statistical testing. Cs-137 was the primary radionuclide confirming the DQOs. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC.Revision 0 14 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 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.

Sr-90 and Pu-238 were the only HTDs, which by analysis, met the criteria for detection (i.e., a result greater than two standard deviations uncertainty).

The highest result for both Sr-90 and Pu-238 was <1% of the Operational DCGL.9530-0001-008F 2.67E-03 0.003 1.02E-01 0.005 (1) The Operational DCGL from Table 2 is 1.05 pCi/g for Sr-90 and 20.1 pCi/g for Pu-238 to achieve 17 mrem/yr TEDE Two (2) biased samples were collected at locations selected by FSS Supervision based on professional judgment and observation.

Gamma spectroscopy analysis was performed by the off-site laboratory to the required MDC.9530-0001-017F 1.82E-01 0.034 (1) The Operational DCGL from Table 2 is 5.38 pCi/g for Cs-137 to achieve 17 mrem/yr TEDE 7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis.

Thirteen percent (13%) of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey." There was acceptable agreement between field split results for Cs-137 at location 9530-0001-006.

However, Cs-137 was not detected in sufficient quantities in the field split results at location 9530-0001-014 to evaluate in accordance with procedure.

Evaluation using the reported results for K-40 resulted in acceptable agreement between the field split results at location 9530-0001-014.

The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation.

Refer to Attachment 4 for data and data quality analysis results.Revision 0 15 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 8. INVESTIGATIONS AND RESULTS One (1) confirmatory sample was collected in scan area 2 at a location exhibiting elevated scan readings.

The sample is denoted as shown in Table 6, with the sample result shown in Table 10 below.Table 10 -Cofirtniat'oyy Sample Resuths,~Sam~e~umbe I Cs4137 ~ ~Fraction of the Sarnle umbr 1)'i/ I pera~tional DCGL~9530-0001-018F 1.67E-01 0.031 (1) The Operational DCGL from Table 2 is 5.38 pCi/g for Cs-137 to achieve 17 mrem/yr TEDE 9. REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil 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.10. CHANGES FROM THE FINAL STATUS SURVEY PLAN No changes were made to the FSS plan.11. DATA QUALITY ASSESSMENT (DQA)The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment, " for completeness and consistency.

The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. 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 2.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 when used in conjunction with the unity rule.Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.Revision 0 16 Revision 0 16 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD For Cs-137, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected.

The difference between the mean and median was -21% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 1.3.All data, assessments, and graphical representations are provided in Attachment 4.12. ANOMALIES No anomalies were noted.13. CONCLUSION Survey Unit 9530-0001 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

Elevated Measurement Comparison and remediation was not required.Cs-137 was 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.

The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.

The survey unit is properly designated as Class 2.The dose contribution from soil is less than 1 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) mrem/yr TEDE.This survey unit is not considered impacted by future groundwater radioactive contamination, as there are underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024); therefore, the dose contribution from future groundwater is zero (0) 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 3 mrem/yr TEDE. Therefore, Survey Unit 9530-0001 is acceptable for unrestricted release.Revision 0 17 Revision 0 17 CENTRAL PENINSULA SURVEY UNIT 9530-0001 RELEASE RECORD 14.
