OLD MAGPIE CREEK CHANNEL WORK UNITS

2 NOVEMBER 2022

1.0 INTRODUCTION

This statement of work (SOW) defines the requirements for remediation of radium-226 (Ra-226) contamination at Installation Restoration Program (IRP) site Old Magpie Creek Channel

(OMCC) (SD290) at the former McClellan Air Force Base (AFB) located in Sacramento County, California. The purpose of this SOW is to implement the excavation remedy selected by the

Follow-on Strategic Sites (FoSS) Record of Decision (ROD) for Ra-226 contaminated soil in the

OMCC. The ROD also selected an institutional control (IC) remedy for other contaminants found at the site, but it is not the purpose of this SOW to implement the ICs or address contamination other than Ra-226.

The Contractor shall furnish the personnel, services, equipment, materials, facilities, and other requirements necessary for, and incidental to, the performance of work set forth herein. Primary technical services shall be performed by individuals who are credentialed members of architectural, planning, science, and engineering professions. Generally, a credentialed professional (a) is licensed (e.g., registered professional engineer) to practice in the state where a facility is located and/or (b) commands the necessary expertise, in terms of knowledge and experience, to undertake the specified task.

1.1 Site Description

The OMCC is a former creek bed, now buried beneath about 12 feet of clean fill, located in the western portion of McClellan AFB, south of the current Magpie Creek channel, in the vicinity of

Building 690 (B690; the capital letter B followed by a number is used throughout this SOW to identify buildings at McClellan AFB) and MAT K (also referred to as the Sun Gro Lot). In plan view (Attachment 1 to the SOW) the buried channel forms a V-shape which intersects the current Magpie Creek east of B690, runs southwest beneath B690 to about the middle of MAT

K, and then runs northwest until it intersects Magpie Creek again. The creek bed was contaminated with Ra-226 and other contaminants. A contaminated layer of soil approximately two (2) feet thick exists at about 12 feet below ground surface (bgs). The cross-section of the buried channel is a crescent shape with a width of approximately 30 ft. at the top and approximately 15 feet at the floor of the channel. The contaminated soil layer is dark in color.

Because of its darker color with respect to the soil above and below it, the contaminated layer is referred to as the gray layer. In much of the former creek bed there is hard pan beneath the gray layer. Soil above the gray layer and the hard pan beneath it appear to be uncontaminated. This gray layer probably consists of sediment from the old creek channel, and can be used as a marker for the creek bed. The eastern end of the site, from the current Magpie Creek to 13 feet east of B690 has been remediated and granted unrestricted radiological release. The portion of the site still needing remediation is about 1,500 feet long, from 13 feet west of B690 through MAT

K to the current Magpie Creek. The remedy for the site is excavation for the radium contamination and engineering/institutional controls for the chemical contamination. This SOW addresses the radium contamination only. Remediation of the site requires (1) all soil contaminated with Ra-226 greater than 2.0 picoCuries per gram (PCi/g) to be excavated and disposed in the McClellan AFB Consolidation Unit (CU), (2) a radiological final status survey to

2 NOVEMBER 2022

be done in accordance with the Multi-Agency Radiation Survey and Site Investigation Manual

(MARSSIM) and a final status survey report (FSSR) to be completed, (3) the grade, surfacing, utilities, and infrastructure be restored to pre-remediation condition, (4) a Remedial Action

Completion Report (RACR) to be completed, (5) the Air Force Radioisotope Committee (RIC) to remove the OMCC from the McClellan AFB Multi-Sites Radioactive Materials (RAM) Permit

(CA-00366-02/01AFP), and (6) the California Department of Health Services (CDPH) to issue a recommendation for unrestricted radiological release (RURR) of the site.

Contamination is known to be present in three locations: (1) Trench 1 which is about 13 feet east of B690 where the previous excavation of the OMCC ended, (2) Trench 2 which is an exploratory trench dug about 15 feet west of B690 following the previous OMCC excavation, and (3) Trench 3 which is an exploratory trench dug approximately 30 feet west of B708 in

MAT K following the previous OMCC excavation. All three trenches have been backfilled and repaved. The western end of Trench 1 is marked by a subsurface slurry wall at the depth of the gray layer. The trenches are shown in Attachment 1 to this SOW. Based on the contamination in Trenches 1 and 2, the Air Force presumes there is contamination beneath B690. However, that contamination has not been confirmed. It is uncertain whether contamination is continuous between Trenches 2 and 3 and how far downstream contamination extends from Trench 3.

Since all soil that exceeds the Ra-226 cleanup level must be excavated and taken to the CU, the

Contractor shall be responsible for determining the bounds of the contamination and demonstrating that all contamination has been excavated.

Building 690 is a slab-on-grade ribbed metal structure 127 feet wide (east-west) and 424 feet 10 inches long (north-south). It has two main bays (North and South) separated by a 31 foot-wide plenum. Each bay has a peaked roof with the ridge oriented east-west at the center line of the bay. The roofs slope from a maximum height of 41 feet 10 ¾ inches to a minimum height of 34 feet. The west side of each bay has hangar doors that open to a width of 144 feet with a vertical clearance of 29 feet. The hangar doors are rail-mounted at the top and bottom. The surrounding area is paved with asphalt (2-inch coarse bituminous surface over a 6-inch aggregate base compacted to 97%) on the east, north, and south and concrete (10-inch concrete over 6-inch aggregate base compacted to 97%) on the west. OMCC runs beneath B690 from northeast to southwest, starting about 13 feet west of the North Bay and running beneath parts of the North

Bay, Central Plenum, and South Bay. The roof of B690 is supported by columns running around the perimeter of the building and a double row of support columns running east-west through the plenum. Eight of the support columns, two on the east edge of the building and six inside the plenum, lie inside the OMCC boundary. It is unknown whether there is Ra-226 contamination beneath these support columns. Detailed drawings of the building are available in Applicable

Documents 6 and 7 (Section 1.4 of this SOW).

Section 3.15 of this SOW) and comply with all relevant DoD, Air Force, federal, state, and local statutes, codes, requirements, and guidance

2 NOVEMBER 2022

• The inspections and documentation the Contractor shall use to verify equipment, materials, and infrastructure construction are in accordance with the specifications and work standards in the final 60% design

• The corrective actions process the Contractor shall use to address deficiencies found during the inspections, including the selection and documentation of corrective actions, time frame for corrective actions, and re-inspection to confirm the implementation and effectiveness of corrective actions.

• Construction Quality Assurance (QA) personnel, responsibilities, and reporting chain

The contractor shall decide, in consultation with the Air Force, whether there will be a single

CQP for the entire project or separate plans for each work unit.

3.7 Health and Safety Plans

The Contractor shall prepare HSPs as required by Title 29 of the Code of Federal Regulations

Part 1910.120 (29 CFR 1910.120), Title 10 of the Code of Federal Regulations Part 20

(10 CFR 20), and AFMAN 40-201. The HSP(s) shall apply to all field activities required to perform the OMCC remediation and infrastructure restoration. The Contractor shall use USEPA guidelines, AFMAN 40-201, and 10 CFR 20 for designating the appropriate levels of protection needed at the site. The Contractor shall maintain written certification that the approved HSP(s) have been reviewed with all personnel that work at the project site prior to their mobilization.

The Contractor shall decide, in consultation with the Air Force, whether separate HSPs are needed for the remediation and construction phases of the work and whether the HSP(s) will be issued as stand-alone documents or as parts of the RAWP and/or CWP. The HSP(s) are IAG primary documents. (CDRL A007)

3.8 Other Plans

The Contractor shall prepare any other plans necessary to describe the work required at the site, protect human health and the environment and comply with federal, state, and local requirements during the performance of this SOW. Such plans might include but are not limited to plans for site security and access control, transportation, dust mitigation, surface water management, storm water pollution prevention, wildlife conservation, and confined space entry. The Contractor shall determine the need for any such plans in consultation with Air Force and the regulatory agencies. These plans shall be primary documents unless otherwise negotiated with the Air

Force and regulatory agencies. The Contractor shall determine in consultation with Air Force whether each plan will be issued as a stand-alone document or as part of the RAWP and/or CWP.

(CDRL A0007)

3.9 Engineering Study Report for B690

The Contractor shall prepare a technical report documenting the results of the engineering study for B690 (see Section 4.3 of this SOW). This will be an Air Force-internal document, and will not require review by the regulatory agencies. The report shall be prepared in draft and final

2 NOVEMBER 2022

versions. The Air Force shall have 30 days to review the draft report, and the Contractor shall issue the final version, incorporating the Air Force’s comments on the draft within 30 days of receiving the Air Force comments. At the Air Force’s discretion this report may be shared with

MBP and Sacramento County. (A001a)

3.10 Biological Resources Field Investigation Report

The Contractor shall prepare a technical report for each work unit documenting the results of the biological resources field investigation for that work unit (see Section 4.1 of this SOW). These will be IAG secondary documents. The associated primary document will be the RACR. The report shall be prepared in working copy, draft, and final versions. The Air Force shall have 30 days to review the working copy, and the regulatory agencies shall have 30 days to review the draft. The Contractor shall issue the draft version, incorporating the Air Force’s comments on the working copy, within 30 days of receiving the comments, and issue the final, incorporating comments from the regulators on the draft, within 30 days of receiving the comments. (A001b)

3.11 Radiation Scoping Survey Reports

The Contractor shall prepare a radiation scoping survey report for each work unit (see

Attachment 1). Pre-excavation data collection is discussed in Section 4.2 of this SOW. The scoping survey reports shall present the following information:

• Locations, boundaries, and MARSSIM classification of each survey unit

• Locations and depths of all samples

• Sampling and analysis methods used

• Laboratory results for each sample

• Quality assurance/quality control (QA/QC) measures used during the sampling and analysis

• Data validation

• Conclusions and recommendations

• Disposal of any waste generated during the sampling, i.e., Investigation Derived Waste

IDW)

• Decontamination of tools and equipment used during the sampling and transport to the lab

• Any restoration done to return the site to its pre-sampling condition

• All necessary backup information needed to decide whether the SAP was followed, human health and the environment were protected during the sampling, and the data are usable for decision making, including but not limited to field logs; boring logs; laboratory reports; visitor access logs; incident, accident, and spill reports; and reports of actions taken to control fugitive dust and surface water run-on and run-off.

The conclusions and recommendations must explicitly address whether the work unit or any part of the work unit requires excavation and whether all or part of the work unit is suitable for unrestricted radiological release without excavation. The Contractor shall decide in consultation with the Air Force whether the scoping survey reports for each work unit shall be issued as

2 NOVEMBER 2022

stand-alone documents or combined into a single document. For a work unit where the sampling shows no excavation is needed, the scoping survey report can be converted to a FSSR if the

Air Force and regulatory agencies agree. (CDRL A001c)

3.12 Final Status Survey Reports

The Contractor shall prepare a FSSR for each work unit (see Attachment 1). Final status surveys are discussed in Section 4.6 of this SOW. The FSSRs shall present the following information:

• Locations, boundaries, and MARSSIM classification of each survey unit

• Surface scan results, instruments used for the surface scans, and instrument calibration and QA/QC

• Locations and depths of all samples

• Sampling and analysis methods used

• Laboratory results for each sample

• QA/QC measures used during the sampling and analysis

• Data validation

• Conclusions and recommendations

• All necessary backup information needed to decide whether the SAP was followed, and the data are usable for decision making including but not limited to field logs, boring logs, and laboratory reports.

The conclusions and recommendations must explicitly state that the ROD cleanup levels have been met, a reasonable effort was made to remove all radioactive contamination, and that the work unit is suitable for unrestricted radiological release. The remediation at OMCC will be phased in order to manage the impact of the remediation on MBP and its tenants, so final status surveys for the different work units will be done at different times. Therefore, the FSSRs for each phase of work shall be issued at different times. The Contractor shall decide in consultation with the Air Force whether the FSSRs for each work unit done during a specific phase of the remediation shall be issued as stand-alone documents or combined into a single document.

(CDRL A001d)

3.13 Backfill Suitability Reports

The Contractor shall prepare one or more technical reports documenting the sampling results for backfill soil (see Section 4.7 of this SOW). The contractor shall decide, in consultation with the

Air Force, whether there will be a single backfill suitability report for all backfill soil used in the project or separate reports for each work unit. These will be IAG secondary documents. The associated primary document will be the RACR. (CDRL A001e)

3.14 Pre-final Inspection Reports and Final Inspection Reports

The Contractor shall prepare a pre-final inspection report and a final inspection report for each work unit. The pre-final inspection report shall be prepared once the work unit has been restored to its pre-excavation condition. It will be used as the basis for the final inspection of the work

2 NOVEMBER 2022

unit. The final inspection report will be prepared after the final inspection has been completed and all final inspection punch list items have been completed. This report will document the final condition of the work unit. These are IAG secondary documents. The associated primary document is the RACR. (CDRL A001?)

3.15 Remedial Action Completion Report (RACR)

The Contractor shall prepare a RACR for the entire OMCC remediation effort (see

Attachment 1). The RACR shall present the following information:

• Remediation conducted at each work unit (If the scoping survey showed no excavation was needed at a work unit and the Air Force and regulatory agencies concur, then the remediation description will summarize the results of the scoping survey and state that no active remediation was required in order to meet the cleanup levels in that work unit.)

• Quantity of soil removed

• Where the excavated soil was disposed

• Depth and width of the excavations and any lay-backs or terracing that was required

• A summary of the data, conclusions, and recommendations from the FSSR demonstrating that the ROD cleanup levels have been met

• The source of backfill material and sampling results showing the backfill meets the ROD cleanup levels

• Disposal of any IDW generated during the final status survey

• Decontamination of tools and equipment used during the remediation and final status survey

• Any restoration, including construction, done to return the site to its pre-remediation condition

• An explicit determination that the remedy selected in the ROD has been performed and the cleanup levels in the ROD have been met

• All necessary backup information needed to decide whether the RAWP was followed, human health and the environment were protected during the remediation, and the data collected during the final status survey are usable for decision making, including but not limited to field logs, boring logs, laboratory reports, visitor access logs, incident, accident, and spill reports, and reports of actions taken to control fugitive dust and surface water run-on and run-off.

The RACR will be largely repetitive of information presented in the FSSRs. However, the

RACR and FSSRs cannot be combined into a single document because they follow different guidance concerning how to determine and document whether remediation is complete. (CDRL

A001f)

3.16 Construction Drawings and Specifications

The Contractor shall prepare construction drawings and specifications (collectively referred to as the design) for all infrastructure requiring construction work to restore to its pre-remediation

2 NOVEMBER 2022

condition. At a minimum this shall include B690. It shall also include the following to the extent they are disturbed during remediation and need to be repaired/restored:

• Paving east of B690 and between B690 and Kilzer Ave.

• Roadway and west margin of Kilzer Ave.

• Utilities and landscaping west of Kilzer Ave.

• B708

• Paving inside MAT K

• B751 and B752

• Paving between MAT K and Magpie Creek

• The liner of Magpie Creek

Construction drawings and specifications will be IAG “other” documents, and shall be prepared in 60% and as-built versions. The as-built version shall reflect the final configuration of the infrastructure as actually constructed and finished. The Air Force shall have 30 days to review the internal draft of the 60% design, and the regulatory agencies shall have 30 days to review the draft 60% design. The Contractor shall issue the draft 60% design, incorporating the Air Force’s comments within 30 days of receiving the comments, and issue the final 60% design, incorporating comments from the regulators, within 30 days of receiving their comments. The

Contractor shall deliver the draft as-built design within 30 days of the end of construction. The

Air Force shall have 30 days to review the as-built design, and the Contractor shall issue the final as-built design, incorporating the Air Force’s comments within 30 days of receiving the comments. (CDRL A009b, A009c)

4.0 REMEDIAL ACTION (RA)

The Contractor shall implement the remedy selected in the FoSS ROD for Ra-226 contaminated soil in the OMCC—excavation to unrestricted use levels with disposal in the CU. The unrestricted use cleanup level for Ra-226 is 2.0 pCi/g. The Contractor shall completely or partially demolish infrastructure such as buildings, utilities, and roads as necessary to implement the remedy, excavate soil that exceeds the Ra-226 cleanup level, transport the contaminated soil to the CU for disposal, perform final status surveys, backfill the excavation, and restore infrastructure to its pre-remediation condition. The Contractor shall restore to its original condition all infrastructure affected by the work performed pursuant to this SOW.

4.1 Biological Resources Field Investigation

The Contractor shall perform a biological resources field investigation in each work unit prior to mobilization and site preparation. The purpose of the investigation is to determine whether any species protected by federal or state statutes or regulations are present at the site and, if so, to define mitigation actions commensurate with federal and state requirements. There are no wetlands or sensitive habitat within the OMCC or its surroundings.

2 NOVEMBER 2022

4.2 Pre-Excavation Sampling

The Contractor shall perform pre-excavation sampling in each work unit. The pre-excavation sampling shall consist of (1) a radiation scoping survey to (a) identify what areas are contaminated above the cleanup level and which areas are not, (b) determine if any of the soil being sent for disposal will exceed CU radiological waste acceptance criteria (WAC), (c) estimate the radiological source term being sent for disposal, and (2) chemical sampling to determine if any of the soil being sent for disposal will exceed CU chemical WAC. Soil samples shall be taken from trenches or continuous core borings in order to make sure the samples are collected from the gray layer. The radiation scoping surveys shall be based on MARSSIM recommendations for a Class 1 final status survey. Radiological soil samples shall be analyzed for Ra-226 by gamma spectroscopy in an analytical laboratory accredited by the DoD

Environmental Laboratory Accreditation Program (ELAP). Chemical soil samples shall be analyzed for OMCC chemical contaminants of concern in an ELAP accredited laboratory. The radiological and chemical pre-excavation sampling results will be used to prepare waste profiles for disposal. Areas that the radiation scoping surveys show exceed the cleanup level must be excavated. (CDRL A001g)

4.3 Engineering Study for B690

The Contractor shall perform an engineering study to determine how best to excavate in and around B690. For the purposes of this SOW, the term excavate is used to mean removal of the contaminated soil from the site. It is not meant to require or imply the use of any specific methodology. The Contractor shall be responsible for selecting an appropriate methodology and obtaining approval for it from the Air Force and regulatory agencies. The Contractor shall perform a radiation scoping survey to determine which parts of the OMCC beneath B690 are contaminated either before or as part of the engineering study (see Section 4.2 of this SOW).

The engineering study must document a technical approach to remove contaminated soil beneath

B690, perform a MARSSIM final status survey of beneath the building, and preserve or restore the functionality, structural integrity, and appearance of B690. At a minimum, the study must address the following:

• How the Contractor will decide what parts of the OMCC inside B690 to excavate, and if any areas of the OMCC under B690 are not to be excavated how it can be demonstrated that the remediation beneath B690 meets the requirements of the FoSS ROD

• How the structural integrity of B690 will be maintained during the excavation, final status survey, and backfill

• Whether the soil beneath the eight structural supports inside the OMCC boundary will be sampled during the pre-excavation sampling and if so how

• Whether the soil beneath the eight structural supports inside the OMCC boundary will be removed during excavation and if so how building integrity and worker safety will be

2 NOVEMBER 2022

maintained during that process and how permanent structural support for the roof will be restored

• If the eight structural supports inside the OMCC…
