3.0 BACKGROUND INFORMATION

The Coeur d’Alene Trust is undertaking a variety of environmental cleanup-related actions at the

Bunker Hill Mining and Metallurgical Complex Superfund Site located in the Silver Valley of north

Idaho, as required by the Coeur d’Alene Trust Agreement with the U.S. Environmental Protection

Agency (EPA). The Coeur d’Alene Trust will implement this work in cooperation with and under the oversight of the EPA. The overall objective for the Coeur d’Alene Trust is to initiate and complete priority work identified in the EPA decision documents, such as the Record of Decision (ROD) and

ROD Amendments. EPA has identified the cleanup of mine and mill sites within the Canyon Creek basin as one of the Coeur d’Alene Trust activities.

Construction of the Canyon Complex Repository (CCR)/Waste Consolidation Area (WCA) and infrastructure improvements have been ongoing and adequate space is available at the CCR/WCA for mine waste disposal from the Standard-Mammoth Reach RA Construction Project and the Frisco

Black Bear Reach RA Construction Project. It is anticipated that all mine waste at the Canyon Creek

Garbage Dump RA Construction Project will be regraded and consolidated on-site and waste removal is not necessary. State Highway 4 will be used for hauling mine waste and backfill materials to and from the Standard-Mammoth Reach, Frisco Black Bear Reach, and Canyon Creek Garbage

Dump projects to/from the CCR/WCA. This RFQ is for the work associated with the Standard-

Mammoth Reach RA Construction Project, the Frisco Black Bear Reach RA Construction Project, and the Canyon Creek Garbage Dump RA Construction Project as described in Section 4.0 of this document.

Respondent. The SOQ should also include brief resumes or bios of key supervisory personnel and descriptions of relevant projects completed by key supervisory personnel, including years of experience completing the types of work outlined in Section 4.0. Additionally, the following topics should be addressed.

• Company Capacity: The three projects discussed in this RFQ will be bid separately;

however, the successful bidder(s) may be awarded more than 1 project bid. The SOQ should provide information that demonstrates the respondent’s capacity to perform multiple projects for the Coeur d’Alene Trust within the same construction year. If the respondent has the capacity to perform multiple projects per year, please provide management, subcontracting, or teaming plan to perform multiple projects. At a minimum, provide organizational charts and resumes for key staff down to project superintendents.

• Subcontracting Approach: The SOQ should provide information on all key subcontractors that the Respondent anticipates using for the RA Construction Projects. Include resumes or bios of key subcontractor employees to be used for the RA Construction Projects.

• Local Labor Requirement: The Coeur d’Alene Trust’s objective is to have 50% local labor and subcontractors for field and office personnel; however, if it is anticipated that this objective cannot be attained by the Respondent, the SOQ should discuss the reasoning. The

Coeur d’Alene Trust Request for Qualifications: 2027 Remedial Action Construction Projects Page 7 percent local labor will be calculated based on average utilization by the hour for Respondent and subcontractor employees. For the Coeur d’Alene Trust RA Construction Projects, local encompasses the area east of the Idaho/Washington border and west of Lookout Pass. The

SOQ must describe the Respondent’s proposed plan to achieve this local labor objective (i.e., subcontracting, hiring local, etc.) or the reasons why this objective may not be achieved.

• Relevant Work Experience: The SOQ should describe work completed by the Respondent that is similar in scope and site conditions to the work described in Section 4.0. Respondent shall include any relevant work experience pertaining specifically to the excavation and hauling of mine waste materials, regrading and consolidating mine waste, stream diversion, construction dewatering, stream reconstruction, bank stabilization, Redi-Rock retaining wall installation, liner installation, storm water construction, adit work, asbestos abatement, traffic control, coordinating with utility companies, working in steep terrain, revegetating, etc.

Respondent shall provide no more than 10 project work experience profiles as part of this section. Each project work experience profile shall include, at a minimum, reference contact information for owner/agency, original bid cost, final cost, project description, Respondent’s role in project, and days completed ahead of or behind schedule.

The Project contracts will require a Site Safety and Health Officer (SSHO) with a minimum of 2 years of experience in implementing safety and health programs at hazardous waste sites where Level C personal protective equipment is potentially required, and with a working knowledge of federal and state occupational safety and health regulations. The

Project contracts will also require that the Respondent prepare and implement an exposure monitoring/air sampling program to identify and quantify safety and health hazards and airborne levels of hazardous substances. The SOQ should describe the Respondent’s health and safety program and experience working on hazardous waste sites. The SOQ must include a resume or abbreviated biography for an individual qualified to fill the SSHO position.

• QAPP Implementation Experience: The SOQ should describe the Respondent’s experience with collecting and tracking field samples, collecting and tracking quality control samples

(e.g., field duplicates and rinsate blanks), managing stockpiled materials awaiting sample results, subcontracting analytical laboratories, and performing data validation.

• Demonstrated Document Management Experience: The SOQ should provide information that demonstrates the Respondent’s ability to comply with rigorous administrative requirements for submittals, document management, and reporting. EPA is the ultimate approving agency for the work, and EPA standard administrative requirements are incorporated into Coeur d’Alene Trust projects.
