Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report 1.0 Executive Summary The Humboldt Bay Power Plant (HBPP) site, owned by Pacific Gas and Electric (PG&E), consists of 143 acres on the southern edge of Humboldt Bay four miles southwest of the town of Eureka, in Humboldt County, in the state of California. PG&E maintains four operational electricity generating units at the HBPP site that run on fossil type fuels and one nuclear powered unit that has been in cold shutdown and safe storage (SAFSTOR) since 1976.

PG&E and HBPP personnel are preparing for the decommissioning of Unit 3 and subsequent license termination. Full-scale decommissioning activities can not proceed until a new fossil plant is constructed and placed into service due to the electricity demands of northern California. The new fossil fueled electricity generating units are being constructed in an area that is referred to as the New Generation (New Gen) area or the New Generation Footprint Area (NGFA). The construction project has been named the Humboldt Bay Repowering Project (HBRP) and is being managed by the Humboldt Bay Generating Station (HBGS) staff, which has a separate management team than the Humboldt Bay Power Plant.

The purpose of the characterization survey was to establish the final radiological status of the soil within the NGFA before the construction of the New Generation Power Plant. Much of this soil will be inaccessible following the New Generation Power Plant construction. Sampling activities were done in conjunction with Oak Ridge Institute for Science and Education (ORISE). ORISE was under contract to the Nuclear Regulatory Commission (NRC) to perform independent verification surveys. The scope of the project consisted dividing the NGFA into two survey units; conducting soil sampling in each of the units, specifically for Cs-137 and Co-60. In addition, a gamma walkover scan of at least 10% of each survey units is performed.

Fourteen samples were collected from each survey unit and sent to GEL Laboratories for gamma spectroscopy analysis. The sample results were compared to an interim DCGL equivalent to the USNRC "Interim Screening Values of Common Radionuclides for Soil Surface Contamination Levels", as they appeared in the December 7, 1999 edition of the Federal Register (64 FR 68395).

All sample results for of Cs- 137 were less than 10% of the 11 pCi/g DCGL and all sample results for Co-60 were less than MDC. The gamma walkover survey did not detect any areas greater than the DCGL.

Therefore, the null hypothesis is false and the NGFA meets the requirements for unrestricted release.

Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report 2.0 Introduction 2.1 Project Background The Humboldt Bay Power Plant (HBPP) site, owned by Pacific Gas and Electric (PG&E), consists of 143 acres on the southern edge of Humboldt Bay four miles southwest of the town of Eureka, in Humboldt County, in the state of California. PG&E maintains four operational electricity generating units at the HBPP site that run on fossil type fuels and one nuclear unit that has been in cold shutdown and safe storage (SAFSTOR) since 1976.

PG&E and HBPP personnel are preparing for the decommissioning of Unit 3 and subsequent license termination. The current electrical generating Units have reached the end of their service life and have been radiologically impacted by the operation of the Unit 3 nuclear reactor. Full-scale decommissioning activities can not proceed until a new fossil plant is constructed and placed into service due to the electricity demands of northern California. The new fossil fueled electricity generating units are being constructed in an area that is referred to as the New Generation (New Gen) area or the New Generation Footprint Area (NGFA). The construction project has been named the Humboldt Bay Repowering Project (HBRP) and is being managed by the Humboldt Bay Generating.Station (HBGS) staff, which is a separate organization from the Humboldt Bay Power Plant.

HBPP performed a radiological characterization of the surface soils of the entire New Gen area in 2007, collecting 14 surface soil samples and performing a gamma walkover scan of all accessible areas. The 2007 radiological characterization was performed in the manner of a MARSSIM final status survey. This data was used to determine the sample set size for the radiological characterization described in this report.

Previous usage of the area consisted of a gravel parking lot, office trailers, a paint shop and sandblasting facility, some storage warehouses, and two diesel storage tanks. These buildings were characterized and removed prior to the soil survey being performed. Since the radiological survey in 2007, most of the soil within the New Generation Footprint is pre-surveyed back-fill due to many utility lines and pipelines being removed from the area.

Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report

2.2 Purpose and Scope

This characterization report describes the objectives, approach, and methodology used during the Radiological Soil Characterization Survey of the New-Generation Footprint Area of the Humboldt Bay Repowering Project. The purpose of the characterization was to establish the final radiological status of the soil before the construction of the New Generation Power Plant. Much of this soil will be inaccessible following the New Generation Power Plant construction.

The New Generation Footprint area is classified as a MARSSIM class 3 area. The surface soils within the footprint of the HBRP have been determined to have the potential to be radiologically impacted by operation of the Unit 3 Nuclear Reactor, according to the Humboldt Bay Power Plant Historical Site Assessment (HSA). Therefore, the area is expected to contain levels of residual radioactivity at a small fraction of established Derived Concentration Guideline Levels (DCGL). The Humboldt Bay Power Plant (HBPP) Historical Site Assessment (HSA) states that because Reactor Unit 3 has been in SAFSTOR status since 1976, the primary radioisotopes that would be present are Cs-137 and Co-60.

Sampling procedures and sampling activity were done in conjunction with ORISE to ensure that unrestricted radiological release of the impacted area could occur. The scope of the project consisted of soil sampling in two separate survey units, specifically for Cs-137 and Co-60, and a gamma walkover scan of at least 10% of the footprint area.

HBPP-RPT-002, Rev 0 6

Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report 3.0 Summary of Technical Approach 3.1 Data Quality Objectives The MARSSIM provides guidance for performing radiological surveys in support of license termination, i.e. Final Status Surveys (FSS). The Data Quality Objective (DQO) process for this radiological survey was stated as follows in the sampling procedure, HBPP-OP-0 15, Soil CharacterizationProcedurefor the New GenerationPlant FootprintArea of the Humboldt Bay Repowering Project:

Step 1: State the problem.

The area south of HBPP Unit 3 is to be cleared for the construction of two new fossil fuel power generating facilities. A Final Status Survey (FSS) cannot be performed because a License Termination Plan (LTP) has not been approved by the United States Nuclear Regulatory Commission (USNRC).

Step 2: Identify the decision.

The decision is to perform characterization of the soil that will be covered by concrete or asphalt in the future, in a method that is consistent with the final status survey that will be performed after the LTP is approved by the USNRC. Surface soil samples will be taken to a depth of six inches.

Step 3: Identify inputs to the decision; The characterization to be performed requires the following procedural or administrative controls to ensure the soil sample analysis data is sufficient to potentially qualify as the FSS and will be addressed in this procedure:

Sample Frequency - This input is based on a projected Derived Concentration Guideline Level (DCGL), a projected standard deviation of the average concentration of radionuclides in the soil samples, and the initial MARSSIM Classification from the HSA.

The projected DCGL and projected standard deviation are assumptions that are used to determine the number of samples required for a survey unit.

Laboratory analysis requirements Step 4: Define the study boundaries.

The characterization will be limited to accessible soils comprising the new generation footprint. The projected interim DCGLs are taken from the USNRC "Interim Screening Values of Common Radionuclides for Soil Surface Contamination Levels", as they appeared in the December 7, 1999 edition of the Federal Register (64 FR 68395). These values will be used until site specific DCGLs are established.

Step 5: Develop decision rule.

-The area will not be considered as meeting the interim DCGLs unless the characterization soil analysis data demonstrates compliance with the release criteria through the non-parametric statistical tests contained within the MARS SIM.

Step 6: Limits on decision errors.

Improper FSS may result in the DPR-7 USNRC license not being terminated by the USNRC. Maintaining the land in the NGRP area under the DPR-7 license is not a cost effective option. Using the interim DCGLs should reduce and/or eliminate the risk of the area failing FSS. The anticipated project DCGLs are expected to be higher than the interim USNRC screening values based on preliminary site specific DCGL development and historical precedence at the Sacramento Municipal Utility District's Rancho Seco Nuclear Plant. Therefore, use of USNRC interim values is expected to be conservative.

Step 7: Optimize the design.

To limit decision errors that could adversely affect the unrestricted release of the HBPP DPR-7 license, specifically in the number of samples to be collected, a conservative relative shift is utilized in the survey design. This conservative factor, based on professional judgment, along with the use of conservative interim DCGLs, is expected to yield a conservative characterization survey that may be used as a future FSS.

3.2 Radionuclides of Concern According to the HSA, the primary radionuclides of concern for beta/gamma decay are Cs-137 and Co-

60. The HSA Alpha decay radionuclides of concern are Am-241 and Pu-239/240; however, previous sampling has shown that these alpha radionuclides are not present. In addition, Co-60 is a primary HBPP-RPT-002, Rev 0 8

Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report marker for alpha radionuclide contamination. At HBPP, alpha contamination is not found without the presence of Co-60. The land area surface scan was performed under the assumption that primarily Cs-137 would be the contributing radioisotope, with a small potential that Co-60 may contribute as well.

3.3 Radiological Survey Criteria Instrument sensitivities, scan rates, and measurements were based on the USNRC "Interim Screening Values of Common Radionuclides for Soil Surface Contamination Levels", as they appeared in the December 7, 1999 edition of the Federal Register (64 FR 68395). USNRC interim screening values for soil are 1l.OpCi/g for Cs-137 and 3.8pCi/g for Co-60. It should be noted that HBPP has developed DRAFT Derived Concentration Guideline Levels (DCGLs) using site specific parameters and using an industrial release scenario, but have not submitted these DCGLs to the NRC for approval. The interim screening values will be used until site specific DCGLs are established.

3.3 Survey Design The New Generation Footprint Area was divided into West and East sections. In order to meet MARSSIM data quality, the sample distribution was generated using a randomly generated layout. For these MARSSIM Class 3 survey units, the sampling layout was generated using the sample design program, Visual Sample Plan© (VSP). Sample locations were plotted on a Sample Location Map. The projected site layout of the New Plants is presented in Appendix A. To be consistent with guidance in the MARSSIM, a relative shift between 1 and 3 was utilized in the survey design. Relative shift, a unit-less value used to determine the number of samples collected from a survey unit, is a function of the applicable DCGLs, the anticipated mean value, and the standard deviation of the sample results. The MARSSIM allows flexibility when choosing the relative shift in order to optimize the survey design.

Conservatism was obtained by developing a lower relative shift that the calculated relative shift, which has the affect of increasing the number of samples.

Sample locations were generated by VSP using the following parameters:

Type A Errors 5%

Type B Errors 5%

DCGLw 11.0 pCi/g Cs-137 LBGR 5.5 pCi/g Cs-137 Width of Gray Region 5.5 pCi/g Cs-137 HBPP-RPT-002, Rev 0 9

-7 Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report Max 0.65 Mean 0.13 Standard Deviation 0.17 The characterization sample set size was developed using a relative shift of 3. The relative shift was calculated by dividing width of the grey region by the standard deviation. In this case, the relative shift was calculated to be 32, but the value of 3 was used as a conservative value. The result is a set of 14 required sample locations for each area, i.e. east section of the NGFA and the west section of the NGFA.

3.4 Sample Identification Samples locations were identified consistently using a format of "NGFA-XXX-##," where "XXX" was replaced with "WST" for the West section and "EST" for the East section. "##" is a sequential number for each section. This was consistent with section 7.3 of HBPP-OP-015 Soil CharacterizationProcedure for the New GenerationPlant FootprintArea of the Humboldt Bay Repowering Project.

3.5 Survey Instrumentation Radiological survey instrumentation was selected to ensure that sensitivities were sufficient to detect the expected radionuclides at the minimum detection requirements. For the gamma walkover survey, a Ludlum Model 2221 scaler/ratemeter with a Ludlum Model 44-10 2"x2"Sodium-Iodide (Nal) detector was used. To log the gamma scan results, the meter/detector combination was coupled to a Trimble GeoXH Global Positioning System (GPS) unit.

3.5.1 Instrument Calibrations Portable electronic field instruments were calibrated in accordance with approved procedures to NIST traceable standards at frequencies not exceeding 12 months by the manufacturer.

3.5.2 Sources The Ludlum Model 2221 with 44-10 was calibrated using a Cs-137 source. The radioactive source used to perform the daily instrument operational checks was a Cs-137, with an activity of 4.82 !ICi.

HBPP-RPT-002, Rev 0 10

Humboldt Bay Repowering Project 4New Generation Footprint Area Soil Characterization Survey Report 3.6 Minimum Detectable Concentration The minimum detectable concentration (MDC) is the concentration of radioactivity that an instrument can be expected to detect radioactivity; typically at a 95% confidence level. For the gamma walkover scan, the MDC was determined from the HBPP Technical Basis Document (TBD) Gamma Scan Detection Capabilities,TBD-006.

Humboldt Bay Repowering Project New Generation Footprint Area Soil Characterization Survey Report 4.0 Summary of Results The following sections summarize the results of the radiological characterization effort. The Analytical Sample Results can be found in Appendix C.

4.1 New Generation Footprint West Area There were 14 sample locations located within the West survey area of the New Generation Footprint Area. Samples were collected from each location. These samples were then sent to an off-site laboratory (GEL Laboratories LLC) for radiographic analysis.

The New Generation Footprint West Area contained no elevated measurements of radioactive materials.

The sample results for Cs-137 are summarized below in Table 4-1. All sample measurements of Cs-137, and Co-60 in the west area were below the MDC.

Mean Max Std Dev 14 2.76E-2 1.95E-1 5.83E-2 4.3 New Generation Footprint Area Gamma Scan The Gamma Scan of the New Generation Footprint Area contained no elevated measurements of radioactive materials. For the purposes of determining the scan MDC, a background count rate of 1700 cpm was used based on the average daily background from the daily pre-operational source checks for the gamma walkover instruments. Per the calculations in TBD-006, an investigation threshold was calculated. The investigation threshold count rate was calculated at 1140 cpm above background (net cpm), which equates to 11 pCi/g Cs-137 and 5 pCi/g Co-60.

The gamma walkover data was recorded by the GPS system. In addition, the Field Technicians listened for detection anomalies using the speaker on the scaler/ratemeter. There were no observed points or areas greater than the investigation threshold during the gamma walkover. The maximum recorded value was 2249 gross cpm or 549 net cpm. The 'area of each survey unit scanned is listed below in table 4-3 and gamma walkover paths are shown in Appendix C.
