Subject:

Radiological Status of the Humboldt Bay Repowering Project Soils

Dear Mr. Sokolsky:

The intent of this letter is to describe the current radiological status of the soils in the Humboldt Bay Repowering Project (HBRP) area. ENERCON Services, Inc. (ENERCON) has determined that the area has no significant detectable residual contamination from Nuclear Reactor Operations at the Humboldt Bay Power Plant (HBPP). This determination is based upon the review of data from three different sampling efforts of the soils in the HBRP area; specifically, the characterizations performed by IT/Duratek in 1997, ENERCON in 2007, and TRC Solutions in 2008 were reviewed. Since the characterization performed by ENERCON for the License Termination Plan (LTP) is still underway,. a summary of the sampling effort and the analysis data from the ENERCON soil sampling effort in the HBRP area in 2007 is attached.

The highlights from the different sampling efforts specific to the HBRP area are as follows:

IT/Duratek Summary - Subsurface borings were advanced to a depth of 4 feet in 9 locations in the HBRP area. Samples were collected at I-foot intervals beginning at 0.5 feet. One location had 6 additional borings in the immediate area. This grouping of samples was to determine the extent of contamination located at the end of a drainage pipe that ran along the northern edge of the train tracks. The tracks and the drain line had been covered by fill and gravel. All samples in the HBRP area were less than the accepted site background of 0.5 pCi/g Cs-137, except the one location with close grouping of borings had three samples at a depth of 3.0 to 3.5 feet with concentrations ranging from 1.34 pCi/g to 1.84 pCi/g and three samples had detectable Co-60 with a.

maximum concentration of 0.9 pCi/g. The location with detectable Co-60 and elevated Cs-137 is on the northern edge of the HBRP boundary and should not be near the foundation of the actual generating plants or ancillary equipment. Additional samples were not collected to confirm or determine the extent of the elevated radioactive material since the concentrations were less than potential release criteria. A drawing with IT/Duratek sample data from samples collected in the HBRP area is included in Attachment 1.

ENERCON Data Summary - The survey of the area indicated no significant detectable contamination from HBPP Unit 3 nuclear reactor operations. One surface soil sample result indicated a Cs-137 concentration of 0.653 pCi/g with a two-sigma uncertainty of+

0.084pCi/g. All other samples Cs-137 results were less than the HBPP site established background of 0.5 pCi/g Cs-137. All results for Co-60, Am-241, Pu-239/240, 4490 Old William Penn Highway Murrysville, PA 15668 phone 724.733.8711 fax 724-325.6383 enercon.com

Mr. David Sokolsky September 2, 2008 Page 2 of 3 Cm-242/244, Sr-90, and Tritium were not detected. The result of the soil sample Gamma radiation surveys indicated no levels of gamma radiation greater than twice background.

Laboratory analysis reports from General Engineering Laboratories are attached as well as drawings of the surface soil sample locations and the gamma walkover measurement locations. Additional samples were not collected to confirm or determine the extent of the elevated radioactive material since the concentrations were less than potential release criteria. A summary of the ENERCON sample collection process, drawings depicting the sample locations, and laboratory analysis results are included in Attachment 2.

TRC Data Summary - TRC Solutions, Inc. advanced 44 borings, with approximately 3 samples per boring, in the HBRP area in support of their Environmental Remedial Investigations in July 2008. In addition to the remedial investigation analyses for non-radiological materials, all samples were submitted for gamma spectroscopy analysis to gain additional knowledge of the subsurface soils in the HBRP area. It was necessary to determine whether or not the soils could be released off site for disposal without restriction, i.e. no radionuclide concentrations derived from Unit 3 operations. All subsurface samples collected from the borings in HBRP Area were less than the site background of 0.5 pCi/g Cs-137, except for one sample with a concentration of 1.23 pCi/g +/- 0.146 pCi/g at a depth of 4.5 feet. Additional samples were not collected to confirm or determine the extent of the elevated radioactive material since the concentrations were less than potential release criteria. A drawing of the sample locations and the laboratory analysis results are included in Attachment 3.

• The aforementioned soil characterization efforts primarily addressed soil exposure routes from the air or groundwater. Two additional exposure routes, burial or subsurface migration along subsurface pipe trenches, may be possible. The operating history and personal accounts do not indicate a high potential for these routes to occur. As a conservative measure, additional sampling will occur during the initial construction phase of the HBRP (i.e. interference removal of buildings, subsurface structures, and pipes and area preparation/grading) to assess whether or not soils were exposed to radioactive material through either of these exposure routes. During the interference removal phase as previously non-accessible soils become accessible, samples will be collected and analyzed for Cs-137. The non-accessible areas include soils below pipes, soils beneath foundations, and soil that does not appear to be native to the immediate area. Objects and other items encountered during excavation of soils in HBRP, will be surveyed with a portable radiation detection instrument before disposal offsite. As a final check, all disposal trucks leaving HBPP with soils or debris for unrestricted release will be scanned independently by the HBPP Radiation Protection Department to ensure compliance with disposal facility waste acceptance criteria Based on the characterization survey results and historical operations at HBPP, a high degree of confidence has been obtained that future worker(s) assigned to the HBRP facility will receive no significant radiation dose above background. Survey results indicate radioactive material concentrations exist in the surface and subsurface soils;. however, the data also indicates that the average concentration should be significantly less than the Nuclear Regulatory Commission's screening levels for residual radioactive material, and will not require any remediation.

Furthermore,. it is ENERCON's opinion that these values are significantly below proposed Derived Concentration Guideline Levels (DCGLs) currently in development for the site.

During the decommissioning of HBPP Unit 3 Nuclear Reactor, a Cross Contamination Prevention and Monitoring Plan will be implemented to ensure the HBRP area and facilities are not impacted

Mr. David Sokolsky September 2, 2008 Page 3 of 3 from Unit 3 decommissioning activities. As part of this plan, routine surveys will be conducted at the facility and continuous environmental air samples will be collected. HBPP has also completed the installation of 7 groundwater monitoring wells to augment the existing network of monitoring wells. Additionally, engineering and administrative controls will be implemented to minimize or eliminate the risk of inadvertent releases of radioactive material during decommissioning activities.

Based on the above discussion, there is no significant radiological impact to construction workers or.the future personnel in the HBRP area.

Sincerely, Health Physicist/Project Manager DGM:dmm cc: John Albers Keith Mahosky Gerald Williams Attachments

ATTACHMENT 2 A Summary Of The ENERCON Sample Collection Process, Drawings Depicting The Sample Locations, And Laboratory Analysis Results

HBRP Area History and ENERCON Surface Soil Characterization Summary EN7ERCON has been contracted by PG&E to develop the License Termination Plan (LTP) for HBPP Unit 3. The characterization effort to support the development of the HBPP LTP is in the final stages and a final report has not been written. Therefore, the following information is summarized from the data contained in the ENERCON Characterization Survey Package 005SS3, New GenerationArea:

Operational History of Survey Unit The HBRP area was not involved in typical plant work activities during operation of the H3BPP Unit 3 Nuclear Reactor. The northern portion of this area is downwind of the Unit 3 stack, for the typical winter south to southeast winds. A large portion of this area has been covered by fill material with about one third of the fill material placed prior to Unit 3 operation and about half of the fill material placed since the beginning of Unit 3 operation. The historical activities in filled portions of this survey area are related to landscaping, operation of the Mobile Electric Power Plants (MEPPs), diesel oil storage, material/equipment storage, painting (and sandblasting to prepare for painting), office space and employee parking. The area has underground piping and electrical conduits. Items of interest in the survey area include the original sanitary sewer leach field for Unit 3 (south of the Oily Water Separator), and the filled drainage ditch/drainpipe that was constructed parallel to the rail spur roadbed.

Detailed Physical Description of the HBRP This survey unit contains the land area where the HBRP will occur. Some of the survey unit, approximately 50%, is covered by asphalt and/or rock. The remaining surface soil is covered with grass and other natural vegetation. This area has been initially classified as a MARSSIM Class 3 area due to the very low potential for radiological contamination to be present based off of soil sample data from the IT/Duratek 1997 Characterization effort.

Characterization Survey Instructions Summary The characterization survey consisted of 14 soil samples and a gamma radiation walkover survey.

The design of the Characterization Survey was based on criteria from NUREG-1757, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSM). Soil samples were collected at locations that were determined by random selection using the current version of Visual Sample Plan. Physical collection of the soil samples was delineated in the survey I

instructions which included the sampling process, field decontamination of tools, sample labeling requirements, and sample location. The procedure HPP-OP-002, Chain of Custody, was used to delineate the required chain of custody process and requirements to ensure the integrity of the samples collected. Soil samples were submitted to General Engineering Laboratories (GEL) for gamma spectroscopy for Cs-137 and Co-60 and for analysis of Am-241, Pu-239/240, Cm-242/244, Sr-90, and Tritium.

The survey instructions also described the procedures to be followed for the gamma radiation walkover survey which covered 100% of accessible surface soil areas using a 2x2 Sodium Iodide (Nal) detector with a scanning speed of less than 0.5 m/s. The gamma walkover survey was' performed using a Ludlum Model 44-10 (2" x 2") Nal detector coupled to a Ludlum Model 2221 meter. A Trimble Pathfinder ProXR Global Positioning System (GPS) was used to log the position and radiation measurements collected during the gamma walkover survey. The GPS was also used to located and log the surface soil samples collected in the area.

Characterization Data Results The survey of the area indicated no significant detectable contamination from HBPP Unit 3 nuclear reactor operations. One surface soil sample result indicated a Cs-137 concentration of 0.653 pCi/g with a twO-sigma uncertainty of+/- 0.084pCi/g. 'All other Cs-137 sample results were less than the HBPP site established background of 0.5 pCi/g Cs-137. All results for Co-60, Am-241, Pu-239/240, Cm-242/244, Sr-90, and Tritium were not detected. The result of the soil sample Gamma radiation surveys indicated no levels of gamma radiation greater than twice background. Laboratory analysis reports from General Engineering Laboratories are attached as well as drawings of the surface soil sample locations and the gamma walkover measurement locations.

" The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance 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+i- the RL is used to evaluate the DUP result.

• Indicates that a Quality Control parameter was not within specifications.

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.

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 M M if above MDC and less than LLD N/A RPD or %Recovery limits do not apply.

ND Analyte concentration is not detected above the detection limit NJ Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

U1 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. Qualifier Not Applicable, for Radiochemistry.

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.

The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than five titnes (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.

• Indicates that a Quality Control parameter was not within specifications.

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.
