SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9802-0000 (Subsurface Area Associated with the West Industrial Site Grounds (non-protected area) is designated as Final Status Survey (FSS)

Class "B" subsurface soils area and consists of approximately eighteen thousand two hundred and ninety two (18,292 M2 ) square meters of area under uninhabited land and is located approximately eleven hundred and eighty eight feet (1,188 ft) from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1). Survey Unit 9802-0000 includes the subsurface soils located under open land area Survey Units 9304-0001, 9304-0002 and 9306-0000.

Additionally parts of survey areas 9302, 9313 and 9512 are located over the footprint of Survey Unit 9802-0000. The southeast quadrant of the survey unit is comprised mostly of rock outcroppings, rock ledge, underbrush and trees. The survey unit has a moderate slope running from southeast to northwest.

The reference coordinates associated with this survey unit are E002 through E008 by S065 through S072 (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 "Classification Basis Summary" conducted for Survey Unit 9802-0000 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, These documents identified a number of events that may have impacted this survey area:

ACR #-95-509-Particle found near West gate during routine survey.

" Plant survey #10-Spot frisk survey performed in southwest protected area indicated some valves appeared to have residual contamination up to 150 corrected counts per minute (ccpm).

" CR# 98-0240- Contamination found in the sludge at the bottom of manhole #3, southwest of the 1 5kev yard.

CR# 98-0992-During a clean-up outside the Radiological Control Area Revision 0 3

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD (RCA), sand was inadvertently scooped up and placed in a dumpster.

Follow-up analysis indicated that the sand contained low levels of radioactive material above the environmental release levels.

" CR# 03-0450-Fixed contamination (3,400 ccpm) was found in the asphalt outside the North RCA gate.

CR# 05-0509-Several Barrels were identified during excavation of the southwest portion of the former Service Building.

CR# 05-0736-The north waste storage tent area was leaking through the north berm.

In July of 2006, the Circulation Water Piping system was excavated from this survey unit (in surface survey area 9306). During the backfill and survey of the excavation, a discrete area of radioactive soil contamination was observed. The area was remediated and re-surveyed and sampled and all post remediation surveys and samples did not indicate radioactive contamination above detection limits. However, because remediation was conducted within the boundaries of survey unit 9304-0001, it was re-classified as a Class 1 area.

The radiological assessments and characterization surveys of subsurface soil in this area to support decommissioning activities commenced in 2005 and continued through 2006 as work progressed.

Sampling was performed in the footprints of the Control Building, Turbine Building, Service Building (excavations II and IV), and Discharge Tunnel (or Circulating Water) excavations. All soil samples were either analyzed at the on-site laboratory or at an approved off-site laboratory for all radionuclides of concern, including HTD radionuclides. Within the subsurface survey area 9802, samples were collected from surface survey units 9302-0000, 9313-0000, 9304-0001, 9304-0002 and 9306-0000. A total of one hundred and forty (140) samples were identified as either post remediation or subsurface characterization samples from this survey area. All of these samples were utilized to determine both the radionuclide(s) of concern and the standard deviation of the sample population for FSS plan development. A summary of the one hundred and forty (140) post remediation or subsurface characterization sample results are provided in Table 1. Following the removal of all above grade commodities, below grade systems and soils identified by previous surveys as contaminated, post-remediation soil samples were taken prior to backfill and grading.

2.17E-01 3.85E-02 The sample results indicate that Cs-137 and Co-60 were the primary radionuclides detected in the sample population and were detected in concentrations up to 21.2% of the Operational Derived Concentration Guideline Level (DCGL) when incorporating the "sum of fractions". Cs-137 was the predominant radionuclide over Co-60 by a factor of 5 to 1. Cs-137 was positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in thirty-three (33) samples where the sample results were predominantly at very low concentrations that were frequently approaching or below detection limits. Co-60 was positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in thirteen (13) samples where the sample results were predominantly at very low concentrations that were frequently approaching or below detection limits. Therefore, both Cs-137 and Co-60 are both identified as radionuclides of concern for FSS.

Thirty-three (33) samples in this group were also sent to an approved off-site laboratory for HTD analysis.

Other than Sr-90 and H-3, no additional HTD radionuclides were positively identified. Sr-90 and H-3 were positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in seven (7) and ten (10) samples respectively. However, none of the thirty-three (33) samples analyzed for HTD were identified at levels above 5% or 10% of the Operational DCGL either individually or in combination. Therefore, Sr-90 and H-3 were de-selected as radionuclides of concern for FSS.

DATA QUALITY OBJECTIVES 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.

Revision 0 5

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD 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 9802-0000 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 HTotal =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) 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.

Revision 0 6

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD 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 mrem/yrvot 0, = 15 mrem/yrsoil + 2 mrem/yrExisting 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) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. During the characterization of the subsurface soils in this survey unit, Cs-137 and Co-60 were identified as the principle gamma emitting radionuclides which were present in sufficient concentrations that could potentially exceed the screening criteria.

Two (2) soil samples were selected to be analyzed by an approved off-site laboratory for all radionuclides specified in Table 2.

This exceeds the LTP requirement that a minimum of 5% of the subsurface soil samples be analyzed by an approved off-site laboratory for all HTD radionuclides of concern as specified by the LTP.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. 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 a sample design that includes either random or biased media sampling.

The DQO process determined that both Cs-137 and Co-60 would be the primary radionuclides of concern in Survey Unit 9802-0000.

Other radionuclides positively identified in concentrations greater than the screening criteria during the performance of this FSS were evaluated to ensure adequate survey design.

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 survey unit was classified as a Class B subsurface soils area as individual sample measurements exceeding the unitized DCGL 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.

LTP Section 5.7.3.2.2 states that there will be a minimum of twenty five (25) measurement locations in a Class B subsurface soils survey unit. In addition, four (4) biased measurements or samples were obtained at the locations of localized remediation efforts where there was the potential for soil contamination. LTP Section 5.7.3.2.2 states that the range of the number of measurements in Class B Revision 0 9

SURVEY UNIT 9802-0000 RELEASE RECORD areas corresponds to the range of values for N (for Sign test), considering a = 0

.05, 13

= 0.05, and a relative shift of < 3.0.

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 B subsurface survey 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 3.

The four (4) locations identified were 9802-0000-002F, 9802-0000-009F, 9802-000-011F and 9802-0000-023F.

Subsequently, four (4) additional sample measurement locations were designated to replace the locations that were deemed to be inaccessible. The location of the samples were determined using Visual Sample Plan (VSP) in accordance with RPM 5.1-14, "Identifying and Marking Surface Sample Locations for FSS in Open Land Areas" using a random selection which is appropriate for relocating a small number of sample locations in a Class B area.

Sample Measurement Locations for the additional samples are listed with the GPS coordinates in Table 4.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0007.

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.

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.

Twenty-nine (29) subsurface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Revision 0 13 Revision 0 13

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD Sample Media for Final Status Survey" and FSS design. Samples were collected using direct push probe technology (GeoProbe).

All samples were obtained to a depth of three (3) meters or where refusal was encountered due to the presence of bedrock prior to reaching a three (3) meter depth. In addition, four (4) sample locations 9802-0000-002F, 9802-0000-009F, 9802-0000-015F and 9802-0000-023F were relocated using the VSP software due to accessibility issues. Large stones, wood and/or root pieces were removed and the soil matrix was homogenized from each 3 meter soil column. 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."

Two (2) samples (9802-0000-008F and 9802-0000-022F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of two (2) samples (9802-0000-01 IF and 9802-0000-013F) for "split sample" analysis.

SURVEY RESULTS All field survey activities were conducted between April 3, 2007 and April 7, 2007.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the twenty-five (25) 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 standard deviations uncertainty).

However, Cs-137 and Co-60 were the only gamma-emitting radionuclides reported in concentrations exceeding the de-selection criteria.

Cs-137 was identified in six (6) and Co-60 was identified in three (3) of the twenty-five (25) 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 lower than the concentrations of Cs-137 found in surface soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063. A summary of the twenty-five (25) samples collected for non-parametric statistical testing results is provided in Table 7.

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

Ten percent (10%) 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 ".

Cs-137 and Co-60 were not detected in sufficient quantities in the field split results at location 9802-0000-011 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 these locations.

An acceptable level of agreement was achieved for both radionuclides of concern in the other field-split sample result (9802-0000-013).

The sample analysis vendor, GEL, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachment 3 for data and data quality analysis results.

8.

INVESTIGATIONS AND RESULTS No investigations were conducted within this survey unit.

9.

REMEDIATION AND RESULTS Some minor remediation activities occurred in this survey unit prior to FSS. All above grade and below grade commodities and facility systems were removed and Revision 0 18

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD properly dispositioned.

Contaminated soils were identified, excavated and removed.

All excavations were characterized and backfilled with "clean" fill prior to performing 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 During the performance of the survey, it was discovered that four (4) of the twenty-five (25) sample locations identified for non-parametric testing were deemed to be inaccessible.

The four (4) locations identified were 9802-0000-002F, 9802-0000-009F, 9802-0000-015F and 9802-0000-023F.

Subsequently, four (4) additional sample measurement locations (9802-0000-030F, 9802-0000-031F, 9802-0000-032F and 9802-0000-033F) were designated to replace the locations that were deemed to be inaccessible. This was accomplished through an addendum 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 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 B.

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 12.

The difference between the mean and median for both Cs-137 and Co-60 were about 20% 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 for both isotopes, as confirmed by the calculated skew of 1.74 for Cs-137 and 0.99 for Co-60.

All data, assessments, and graphical representations are provided in Attachment 4.

12.

ANOMALIES No anomalies were noted.

13.

CONCLUSION Subsurface soils Survey Unit 9802-0000 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 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 survey unit is properly designated as Class B.

SUBSURFACE AREA ASSOCIATED WITH THE WEST INDUSTRIAL SITE GROUNDS (NON-PROTECTED AREA)

SURVEY UNIT 9802-0000 RELEASE RECORD The dose contribution from soil is 0.1 mrem/yr TEDE based on the average radionuclide concentrations in 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 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 4.1 mrem/yr TEDE.

Therefore, Survey Unit 9802-0000 is acceptable for unrestricted release.

Cheryl; We're sending 31 samples under MSR 07-0143 to GEL today. All of the samples have a 7 day TAT request. It is acceptable for GEL to use the traced/untraced Tc-99 process for these quick TAT requests. See attached COC for requested analyses.

We will be sending another batch toward the end of the week (about 17-21 samples).

Thanks; Rick Gault CYAPCO 860-267-3903 Content-Description: COC 07_00115_00116_00117.pdf COC 07_00115_00116_00117.pdf. Content-Type:

Range AnIst Date Tim4e Notes:

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.

Ul 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 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.
