1.0 SCOPE

This requirement is for environmental remediation activities at Fairchild Air Force Base (AFB).

This Performance Work Statement (PWS) defines the scope of environmental services necessary to conduct site restoration under the Optimized Remediation Contract (ORC). The range of activities includes maintenance of established remedies, optimization at applicable sites, and achievement of site-specific objectives. The Contractor shall undertake Environmental Remediation activities to achieve Performance Objectives (POs) at thirteen (13) Installation Restoration Program (IRP) sites.

NOTE: For purposes of this ORC, the term “Government” includes the Air Force (AF) and 772nd ESS. While regulators are a governmental entity, they are also a third party over whom the Air Force has no control and, as such, will be referred to as “regulators.”

1.1 Introduction

Fairchild AFB is in eastern Washington, 12 miles west of the City of Spokane, in Spokane County, and occupies approximately 4,300 acres. Fairchild AFB was established in 1942 as the Spokane Army Depot. In 1950, the name was changed to Fairchild AFB. The 92d Air Refueling Wing (ARW) is the host unit at Fairchild AFB. Fairchild AFB is also home to the 141st ARW;

the 336th Training Group, which operates the USAF Survival, Evasion, Resistance, and Escape School; Armed Forces Reserve Center; and the Joint Personnel Recovery Agency. Its primary mission is to maintain and repair aircraft, primarily large aircraft such as bombers and tankers.

Fairchild AFB is regulated by the U.S. Environmental Protection Agency (EPA), Region 10 and the Washington Department of Ecology (WA Ecology) under a Federal Facilities Agreement (FFA) signed in 1990. It has been on the National Priorities List (NPL) since March 1989.

Remediation activities at Fairchild AFB are being conducted pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA), and the State Voluntary Cleanup Program (VCP). Regulatory oversight is provided by EPA Region 10 and the WA Ecology.

1.2 Overview of ORC Scope and Requirements

The Contractor shall perform all the necessary environmental remediation activities needed to achieve the performance requirements described in Section 1.3 of the PWS, inclusive of the POs listed in Table 1, Performance Table, and additional scope in Section 1.3.2. This PWS and the enclosures listed below detail the project requirements needed to meet the AF objectives:

• Enclosure 1 – Acronyms and Definitions

• Enclosure 2 – Government Furnished Information (GFI) o Enclosure 2A – Administrative Record Spreadsheet o Enclosure 2B – GFI Compact Disc

• Enclosure 3 – Government Furnished Property (GFP)

• Enclosure 4 – Community Involvement Plan (CIP) Guidance version 4

The intent of the ORC initiative is to advance site cleanup during the Period of Performance (POP) in the most efficient and cost-effective manner, as supported by a cost-benefit analysis and exit strategy that achieves the greatest reduction in life-cycle cost (LCC). The AF is interested in substantial reduction of long-term environmental liabilities and total LCC.

Technical approaches that are simply reduced to a minimal level of effort with no well-planned contingencies provide no assurance to the Government that the POs will be achieved without work stoppages or change orders which is not in keeping with the intent of this performance-based contracting effort. The AF is required to implement remedies as necessary to enable the mission, protect human health and the environment, and comply with laws and regulations. The goal of the ORC initiative is to ensure the AF continues to fulfill all facets of its Environmental Restoration Program (ERP) mission by effectively and efficiently managing the program in a performance-based, results-oriented, and cost-conscious framework.

The AF requires that all sites be cleaned up to standards that allow for the current or reasonably anticipated future land use of the property. Accurate documentation and reporting of contaminant removal and cost savings are critical adjuncts to optimization success. In keeping with Defense Environmental Restoration Program (DERP) and Air Force Instruction (AFI) 32- 7020, the AF defines optimization under the ORC as the reduction of contaminant mass and concentrations, reduction in LCC, or any combination of activities leading to acceleration of Response Complete (RC)/Site Closeout (SC) as a result of remedial implementation the Contractor undertakes, above and beyond what is required to maintain compliance in accordance with an approved Decision Document (DD).

The Contractor shall maintain compliance with all binding agreements (including but not limited to DDs/Records of Decision (RODs), Proposed Plans, RCRA Permits) that are currently in place until no longer required, or an alternate approach is approved. The contractor shall conduct DD/ROD amendments or Explanation of Significant Differences (ESD) as required to implement new approaches.

The Contractor shall function as an integral team member in support of the Air Force Civil Engineer Center (AFCEC) mission to include the sharing of information with other AFCEC Contractors, and AF personnel, in cooperation with community stakeholders, regulators, and other Government entities.

Requirements for efficient management of this contract include the achievement of the POs in the Performance Period (PP) per Table 1 and work described in Section 1.3.2 of this PWS.

Requirements include timely identification and solution of impediments to successful project execution. The Contractor shall provide all personnel, equipment, supplies, tools, materials, and other items necessary to perform the tasks defined in this PWS. The Contractor is solely responsible for reviewing all available information and forming their independent, professional conclusions/interpretations of site conditions and requirements to achieve the POs of this contract within PP specified. AFCEC will rely on the Contractor’s expertise in recognizing and addressing problematic issues during the execution of this contract. The Contractor shall perform all work in accordance with federal, state, and local statutes and regulations. The Contractor shall also comply with installation regulations. Remedies shall conform to environmental permits, DD requirements, and/or other legal requirements. The Contractor shall continue work throughout the entire duration of the POP. The expectation is that the Contractor will complete all field activities within the POP. If reporting on the field activities extends beyond the POP it is expected that the Contractor will turn over all data, native files, field documentation, etc. required for the reporting to be completed under subsequent contracts.

Conversely, the Contractor is expected to complete reporting for the field activities completed in the calendar year of the award unless specified otherwise. The Contractor’s local office presence will be relied upon to provide rapid-response actions for field activities and on-site meetings.

POs are identified in Section 1.3.1 Table 1: Performance Table and in Section 1.3.2. POs that are in keeping with standard DERP milestones are defined in Enclosure 1. In addition, for certain categories of sites, the AF has set POs based on current site conditions and consistency with the POP of the contract and ORC goals.

1.2.1 Specific Scope Discussion and Limits

The scope of this contract is to perform environmental remediation services listed in Table 1 and Section 1.3.2. The ORC Contractor shall assume contractual liability and responsibility for achieving the POs. If the selected technical approach is not working, as demonstrated by the trends in the performance model, the Contractor shall develop and implement a revised technical approach to achieve the POs, including DD amendments, if required, to implement the remedial approach. This scope includes all known contaminants linked to the specific sites per Table 1 of the PWS (includes contaminants on, under, or sourced at/migrating from the specific sites) without regard to quantity (e.g., plume size, concentrations). See reference to Section 1.3.2.j of the PWS for exclusions. The AF remains statutorily responsible for all sites listed in Table 1 and work described in Section 1.3.2.

1.2.2 Preliminary Assessment/Site Inspection, Remedial Investigation or Remedial

Investigation/Feasibility Study (including Supplemental Investigations), and Decision Document

Table 1 of the PWS identifies Preliminary Assessment/Site Inspection (PA/SI), Remedial Investigation (RI) or RI/Feasibility Study (FS), including Supplemental Investigations, and DDs as the PO for selected sites. The Contractor is responsible for achieving these POs as identified in Table 1 and work described in Section 1.3.2. See PO definitions in Enclosure 1, Acronyms and Definitions.

1.2.3 Response Complete or Site Closeout

NOT APPLICABLE

1.2.4 Remedial Action-Operation with Optimization

NOT APPLICABLE

1.2.5 Remedial Action-Operation and Reduce Life Cycle Cost; Long Term Management and Reduce Life Cycle Cost

NOT APPLICABLE

1.2.6 Remedial Action-Operation or Long-Term Management (as appropriate) Table 1 of the PWS identifies Remedial Action-Operation (RA-O) or Long-term Management (LTM) in accordance with the approved DD/ROD as the PO for selected sites. The Contractor shall achieve the following objectives for each RA-O and LTM site:

• Maintain compliance with all DDs and permits (currently in place or to be approved) throughout the PP. Update or revise site-specific work plans, monitoring plans, and/or DDs, as appropriate.

• For RA-O sites, develop performance models addressing all Contaminants of Concern (COC)s and breakdown products. Refer to Section 8.1.3.1, Performance Models.

• Provide a realistic projection to achieve SC or RC after the POP (the Contractor shall identify which PO is the optimal endpoint).

1.2.7 Alternate Objectives

This section and the subparagraphs below describe the Alternate Objective Sites and a general overview of the work associated with these sites. Please see Table 1 and work described in Section 1.3.2 for specific elements of work required for each site with an Alternate Objective PO. These sites have complex attributes that have, to date, inhibited progress toward the achievement of RC. For Alternate Objective sites, as for all sites in Table 1 of the PWS where applicable, the Contractor shall maintain compliance throughout the POP of the contract with all existing regulatory requirements, including but not limited to regulations, FFAs, RCRA Permits, final or interim RODs, or other equivalent remedial DDs. The Contractor is responsible for implementing changes to the monitoring program based on activities conducted in the Advanced Site Characterization (PWS Section 1.2.7.1), including the addition and decommissioning of wells in the monitoring well network as agreed by all parties and the addition of new delineation monitoring where new information indicates our understanding of the plumes is changed.

Based on technical review of existing site conditions/activities, the AF placed sites in the category of Alternate Objective if one or more of the following conditions exist:

• Achieving RC is expected to require substantially longer than 30 years.

• Achieving RC is unattainable with standard characterization and/or existing remediation technology due to technical or other limitations related to site conditions.

• Achieving RC is anticipated to require advanced site characterization technologies to improve the Conceptual Site Model (CSM), determine appropriate remedial technology, and/or characterize recently regulated contaminants.

The AF will use data and information obtained during execution of this PWS to determine restoration potential and future investment strategies at Alternate Objective sites. Each Sub- CLIN for the Alternate Objective sites will only be awarded if the activities are needed to determine the future investment strategy for the site. The decision to award each Sub-CLIN resides solely at the discretion of the AF.

The Contractor shall conduct project scoping sessions before work plan development and throughout the planning and execution of the project to meet the PO, including the Installation Point(s) of Contact (POC[s]): the AFCEC Program Manager (PM), Remedial Project Manager (RPM), the AF technical support team, and the Contracting Officer’s Representative (COR).

Upon approval by the AF and the COR, the Contractor shall participate in scoping sessions with the regulators as appropriate.

1.2.7.1 Advanced Site Characterization

Based on existing data, the AF has determined that the existing remedial approaches at the Alternative Objective sites are not achieving satisfactory remedial progress toward their intended goals. In order for the AF to determine the best path forward for these sites, the Contractor shall conduct Advanced Site Characterization to collect data to update and refine the CSM in order to achieve the following goals: (1) Fill data gaps; and (2) Collect data needed to: (A) Determine why existing and previous remedial actions are not effective at achieving remedial progress; (B) Determine appropriate remedial technology(ies) based on site conditions; C) Develop remediation design parameters for recommended technology(ies); and D) Determine extent and concentrations of recently regulated contaminants, if required.

Advanced Site Characterization includes one or more of the following three activities: (1) Supplemental Site Investigation (SSI), (2) Revised CSM, and (3) Groundwater Monitoring Program Update.

1.2.7.1.1 Supplemental Site Investigation

The Contractor shall conduct a SSI to collect data necessary to improve the CSM, determine appropriate remedial technology, support remediation design and construction, and/or characterize recently regulated contaminants. The Contractor shall implement advanced characterization methods, both established approaches and state-of-science techniques consistent with AF, regulatory, Interstate Technology and Regulatory Council (ITRC), and Strategic Environmental Research and Development Program/Environmental Security Technology Certification Program (SERDP/ESTCP) guidance to attain these objectives. Data collection includes better definition of geology, hydrogeology, geochemistry, and/or source(s) and distribution of COCs, as required. The Contractor shall evaluate the need for, and collect the following data where appropriate: (1) Source Zone Delineation; (2) Source Mass/Extent1,2,3; (3) Vertical and lateral extent of contamination, if not sufficiently defined; (4) Plume Stability4; (5) Migration pathway, rates, and fluxes in 3-D; (6) Mass distribution; (7) Biogeochemical conditions and influences on contaminant degradation pathways; (8) Impact of recent and historical remedies on site conditions; and (9) Comprehensive Risk including the vapor intrusion pathway.

The SSI report shall document data collection efforts to include a risk evaluation, if appropriate.

The Contractor shall evaluate and provide recommendations regarding whether additional source control is needed or whether the plume, or portions of the plume, are amenable to natural attenuation by conducting source strength and plume stability evaluations as needed.

1.2.7.1.2 Conceptual Site Model

The Contractor shall develop a revised CSM in 3-D to include establishing or updating existing fate and transport models based on existing data and data gathered during the SSI. The CSM should cover the source area and the distal plume, to include the lateral and vertical extent of the contaminants in the context of geologic/hydrogeological parameters and the remedial actions conducted to date.

1.2.7.1.3 Groundwater Monitoring Program Update

The Contractor shall evaluate the current horizontal and vertical well distribution to determine if the following can be properly evaluated:

Remedy performance in treatment areas

Hydrogeology, plume geometry, horizontal and vertical plume stability, and matrix diffusion across site

Plume migration through use of perimeter/boundary wells and sentinel wells Based on the well network evaluation, coordinated and approved by the Government and regulators (if required), the Contractor shall optimize the monitoring well network to include adjusting sample collection frequency and the addition of new wells as appropriate. The Contractor shall update the Basewide or Site-Specific Monitoring Plan or other equivalent document, as appropriate.

1.2.7.2 Remedy Evaluation and Recommendation

Based on all existing data and data gathered during the Advanced Site Characterization, the Contractor shall evaluate the existing active and/or passive remedy(ies)5,6,7. The Contractor shall provide recommendations to augment, modify, and/or replace the existing remedy8. The evaluation and recommendations will include a cost-benefit analysis and evaluation of the usability, expandability, and/or discontinued use of any existing infrastructure. All remedy recommendations must include a performance model addressing all COCs and breakdown products. Refer to Section 8.1.3.1, Performance Models.

Where necessary to evaluate the proposed technology, the Contractor shall conduct pilot-scale technology demonstrations. The Contractor shall identify appropriate remedial technologies and target zones, design/plan, conduct, and evaluate the pilot and/or field scale technology consistent with AF, regulatory, and ITRC guidance. The Contractor shall determine performance

monitoring criteria and identify a control sub-site (current state) for comparison and to evaluate results.

In some instances, achievement of RC may not be feasible with currently available technologies within a reasonable timeframe. If this is the case, Contractor shall develop and evaluate alternatives for site management that will be protective of human health and the environment. If this recommendation is made, it must include the rationale, recommended target when active remediation can cease, and a strategy for obtaining regulatory approval.

1.2.7.2.1 Cost/Benefit Analysis

The Contractor shall provide a cost/benefit analysis for proposed alternatives. Alternatives may include optimizing the remedy in the DD or other remedies with the potential for better performance. All alternatives identified shall be evaluated against one another to determine which alternative can achieve RC in the shortest time and has the lowest overall LCC. The cost/benefit analysis shall include:

• A focused analysis of alternative approaches, to include conceptual designs and engineering cost estimates. The analysis shall identify the total cost of executing the optimized remedy (including the plan and reports).

• An estimate of the reduction of LCC of each alternative evaluated.

• Any risk inherent in implementing the alternative optimized remedy.

• A summary comparison of the LCC and risk of each alternative in a cost/benefit analysis that clearly states the recommended alternative.

1.2.7.3 Decision Document Amendment

Based on the results of the remedy evaluation and recommendation, it may be necessary to amend the Decision Document to augment, modify, and/or replace the existing remedy. If warranted, the Contractor shall update the Decision Document.

1.3.2 Additional Scope Discussion and Limits

In addition to the requirements identified in Table 1, the Contractor shall be responsible for:

Operations and Maintenance (O&M) of all remediation equipment to include all wells belonging to the FAFB ERP and well abandonment with AF and regulatory approval (if required) when the well is no longer necessary.

Establishing a quality control/quality assurance process to ensure documents are of an acceptable quality and do not contain typos, formatting issues, contradictory information in tables and text, etc.

Contaminants for which there are promulgated federal, state, or local standards.

AFCEC may determine during the POP that clean-up needs to be accomplished at a particular site where PFAS is present if there is a promulgated State Maximum

Contaminant Level (MCL) that is approved for use by the Department of Defense (DoD) as an Applicable or Relevant and Appropriate Requirement (ARAR) standard. These determinations may result in additional sites or additional work related to existing sites being added to the contract via modification.

1,4-Dioxane investigations shall be conducted as described in “Interim Air Force Guidance on Sampling and Response Actions for 1,4-Dioxane at Operational and [Base Realignment and Closure] BRAC Installations,” dated 24 May 2013. The Contractor shall present results in one Tech Memo/Report per installation documenting the analytical methods and maps depicting sampling locations within the trichloroethene (TCE) plume and sample analysis results.

Manage and dispose of investigation-derived waste (IDW) media associated with PFAS in accordance with the AF Guidance Memorandum “Interim Guidance on Destruction or Disposal of Materials Containing Per- and Polyfluoroalkyl Substances in the United States” dated 11 July 2023, AF Guidance Memorandum “Guidance on Incineration of Materials Containing Per- and Polyfluoroalkyl Substances” dated 14 July 2023, and Section 4.14.2 of this document.

The Contractor shall also comply with federal, state, local, and base requirements for any task involving the transportation of hazardous wastes and/or contaminated materials to off-site treatment, storage and/or disposal facilities. This includes 40 Code of Federal Regulations (CFR) Parts 260 and 263, 49 CFR Parts 172, 173, 174, 178, and 179, and all other applicable local, state, and federal transportation regulations.

The Contractor shall test IDW for PFAS using EPA test method 1633 as required for waste acceptance.Washington waste disposal facilities are rejecting all waste without PFAS sampling, therefore all IDW must be analyzed for PFAS. If waste contains detectable levels of PFAS, it must go to a Subtitle C landfill (closest is in Oregon). If waste does not have detectable levels of PFAS it can go to the local landfill.

For wastewater treatment sites that may be retrofitted for PFAS during the ORC POP by a non-ORC contractor, ongoing O&M activities – such as filter changeouts and the collection of influent, mid, and effluent samples for evaluation – may be added to the ORC contract via modification.

Ensuring that remedial actions do not negatively impact the distribution of any other contaminants and/or emerging contaminants (e.g., PFAS, 1,4-dioxane).

Basewide monitoring well network inventory, inspection, affixing monitoring well ID tags, and repair Annual Report (to include basewide maps).

An Annual Basewide LUC report including the Voluntary Cleanup Program (VCP) sites.

Preparing for (create and mailout invitations, support poster sessions) and conducting RAB meetings; performing community outreach activities; and preparing CIPs or Updates as described in Sections 4.6.1, 4.6.2, and Enclosure 4.

Participation in Town Hall meeting presentations and providing posters when necessary.

Generating a Basewide Well and LUC Boundaries map and updating annually.

Providing maps of proposed affected areas as required for all dig permits.

For off-base sampling locations, preparation of necessary Access Agreement, Easements, etc., on AF behalf, and/or coordination/scheduling of field activities, or providing results to homeowners.

The Contractor shall NOT be responsible for:

Reasonably unanticipated contaminants at sites identified in Table 1 (e.g., previously undetected mercury within a TCE plume); however, Contractors would be responsible for reasonably anticipated contaminants (e.g., vinyl chloride in a TCE plume).

Remediation or treatment of contaminants for which there are no promulgated federal, state, or local standards or AF agreements at time of contract award unless included via modification.

Official regulatory changes occurring after contract award, as documented in Administrative Code, laws, and regulations, e.g., decrease in residential Soil Cleanup Target Levels, Groundwater Cleanup Target Levels, etc.

Sites not identified in Table 1.

4.1 Project Management Plan

The Contractor shall develop and maintain a detailed PMP. The PMP shall specify the project’s resources and tasks corresponding to the Sub-CLINs for this contract as required for the planning, execution, control, and completion of the stated POs. At a minimum, the PMP shall include the following sections: technical approach for achieving the POs in accordance with the PWS, management approach including sub-contractor management, organization and integration of the project team, schedule management, project controls, transitional activities, risk management, quality management, health and safety management, procurement management, security management, and communications plans. The Contractor is responsible for complying with the “Optimized Remediation Contract (ORC) Program Management Plan (PMP) Guidance” latest version, as well as standard industry practice. Clarification on PMP content and the level of detail required to address the ORC program shall be provided by the COR.

The PMP shall demonstrate a comprehensive decomposition of each work package/PO deliverable and exhibit a clear and concise correlation between the PWS, IMS, and MPS. The Contractor is responsible for complying with the guidance for the Development of Contract Line Item Number Structures, Integrated Master Schedules, and Milestone Payment Schedules (CLIN, IMS, and MPS Guidance) per the latest version of the “Optimized Remediation Contract (ORC) Program Management Plan (PMP) Guidance.”

The first draft of the PMP shall be submitted in accordance with Table 1. The Draft PMP and subsequent revisions shall be subject to AF review and approval. The Final PMP shall be due within fourteen (14) calendar days of receipt of AF comments on the Draft versions. The Contractor shall maintain the PMP throughout the duration of the contract utilizing dated page changes and track change deletions and insertions (electronic copies) as practicable. Whole document PMP updates during the life of the ORC may be necessary based on the accumulation of small incremental changes or significant changes (e.g., contract requirements, technical approaches, risk and issue management, or key personnel). The Contractor shall prepare two whole document updates during the POP of the ORC. The AF will determine when PMP updates are warranted.

4.2 Schedule and Planning Requirements – Integrated Master Schedule The Contractor shall prepare and submit an Integrated Master Schedule (IMS) in hardcopy and in electronic format (Microsoft Project, Adobe Acrobat portable document file (.pdf)). The Baseline IMS will be finalized during development of the PMP, and the Contractor shall update monthly.

The following are minimum AF requirements for the IMS:

• Presents a realistic sequence and timing of all activities and documents necessary to demonstrate achievement of the PO within the PP. The IMS shall demonstrate full compliance with the PWS, including achieving POs within the required PP.

• Utilizes a realistic calendar (i.e., work week of five eight-hour days, no submittals on Federal holidays, etc.), appropriate logic ties, clearly defined constraints, and identifies key points where risk mitigation/contingency actions may need to be taken.

• Includes the following columns in the exact order as shown below:

o Installation Name: Identify Enterprise Environmental, Safety, and Occupational

Health Management Information System (EESOH-MIS) Installation Name per Table 1. The Installation name must be included in every line of every Sub-CLIN.

o Site Number: Identify EESOH-MIS Site ID per Table 1 and Site Alias, if applicable. The EESOH-MIS Site ID must be included on every line of the IMS where applicable.

o CLIN/Sub-CLIN: Identify CLIN and/or Sub-CLIN per Section B of the contract.

The CLIN or Sub-CLIN must be included on every line of the IMS, as appropriate.

Note: Sub-CLINs for compliance activities (routine regulatory requirements to comply with binding agreements) are denoted as ####CX and Sub-CLINs for performance activities (remedial advancement or progress towards the PO) are denoted as ####AX. For example, for POs of RA-O with Optimization, the Performance Goal “A” Sub-CLINs are specifically for reporting progress in achieving the performance goal identified in the performance model (separate reports for each year). This requires a separate report identifying the most recent result for the performance indicator(s), usually a COC concentration, and how that compares with the projected value of the performance indicator in the performance model. The “C” Sub-CLINs are specifically for operating the remedy and reporting all required results, such as COC concentrations, geochemical, groundwater elevations, etc.

o Task Description: Include detailed description of all activities (e.g., meetings, permitting, site access, work plans, mobilization, field work, documents, reviews, coordination with stakeholders, etc.) associated with achievement of the PO, and a clear indication of regulatory CERCLA/State Program phase completions (e.g., RIP Achieved, RC Achieved, etc.) and PO achievement.

Activities should not be grouped together; every activity must have a separate entry. For example, the IMS must show separate activities for sample collection, sample analysis, data validation, ERPIMS upload, injections (mobilization, substrate injection, demobilization), and well installation (mobilization, drilling/well completion, demobilization).

o Start and Finish Dates: Document Start date and Finish date for each required activity and document, including appropriate durations and Government and Regulatory review periods in accordance with Section 6.2 of the PWS.

Include an obligation date, notice to proceed date, or projected award date as the first activity for each Sub-CLIN.

Include a clearly identified final field work (e.g., FINAL FIELD

ACTIVITY) Start date and Finish Date for each site (i.e., indicate when the final set of field activities such as injections, groundwater sampling, or others will be complete).

o Milestone Payment Amount:Include negotiated amount consistent with the approved MPS ensuring the sum of all milestone payments equals the value of the CLIN/Sub-CLIN per Section B of the contract.

o Percent Complete: Record completion status of all activities and documents as approved by the COR.

o Predecessor and Successor: Define relationships and constraints associated with activities and documents.

The Contractor shall prepare and maintain the IMS in accordance with the PMP Guidance (latest version). The Contractor shall maintain and submit an IMS monthly in electronic format in accordance with the requirements above and include updates to progress and approved changes (e.g., Government or regulatory review periods, technical approaches, milestone payment updates, or contract requirements). The IMSs shall be submitted electronically to the Contractor’s ORC document repository and in accordance with instructions from the COR. The Contractor shall prepare and maintain the IMS in accordance with the PMP Guidance (latest version).

4.3 Milestone Payment Schedule

The Contractor shall prepare and submit an IMS, from which they will extract the information required to generate an MPS and will submit each as two separate files. NOTE: The MPS is not part of the proposal. Award of the contract does not equate to final acceptance of the IMS or of the MPS. The IMS and MPS, including payment milestones and percentages, will be discussed and agreed upon among the Government and Contractor during the review of the initial PMP/IMS/MPS and approved by the COR.

The following are minimum AF requirements for the MPS:

• Presents appropriate milestone payments considered integral and necessary to the achievement of the POs.

• Ties interim and final milestone payments to performance models as described in Section

8.1.3.1 (also see Sections 1.2.6 and 1.2.7.2).

• Includes a reasonable number of milestone payments per CLIN/Sub-CLIN based on the scope and anticipated duration to achieve CLIN/Sub-CLIN objective and/or PO.

• Aligns with the CLINs/Sub-CLINs in Section B of the award document and includes the following columns:

o Installation Name: Identify EESOH-MIS Installation Name per Table 1.

o EESOH-MIS Site ID: Identify EESOH-MIS Site ID per Table 1 and Site Alias, if applicable.

o CLIN/Sub-CLIN: Identify CLIN and/or Sub-CLIN per Section B of the contract.

Note Sub-CLINs for compliance activities (routine regulatory requirements to comply with binding agreements) are denoted as ####CX and Sub-CLINs for performance activities (remedial advancement or progress towards the PO) are denoted as ####AX. For example, for POs of RA-O with Optimization, the Performance Goal “A” Sub-CLINs are specifically for reporting progress in achieving the performance goal identified in the performance model (separate reports for each year). This requires a separate report identifying the most recent result for the performance indicator(s), usually a COC concentration, and how that compares with the projected value of the performance indicator in the performance model. The “C” Sub-CLINs are specifically for operating the remedy and reporting all required results, such as COC concentrations, geochemical, groundwater elevations, etc.

o Milestone Payment Identification Number: Include unique number assigned to each milestone payment for tracking purposes.

o Milestone Payment Description: Include detailed description of definable and measurable step considered integral and necessary to the achievement of the CLIN/Sub-CLIN objective and/or PO.

o Milestone Payment Amount: Include negotiated amount ensuring the sum of all milestone payments equals the value of the CLIN/Sub-CLIN per Section B of the contract.

o Milestone Payment Percentage: Include percentage of the milestone payment in relation to the total CLIN/Sub-CLIN value. The final payment milestone(s) within a CLIN/Sub-CLIN demonstrating achievement of the CLIN/Sub-CLIN objective must be a minimum of 20% of the total CLIN/Sub-CLIN value. This may include both the AF approved and regulator approved versions. Milestones should not be front-loaded but instead be commensurate with the work completed.
