Remedial Investigation/Feasibility Study and Corrective Action Plan

The Confederated Tribes of Siletz Indians (CTSI) are seeking qualified environmental professionals (QEPs) to conduct a comprehensive Remedial Investigation/Feasibility Study (RI/FS) and Corrective Action Plan (CAP) for the Upper Mill Property located in Toledo, Oregon. The procurement targets environmental assessment and remediation services for a former industrial site with potential contamination risks from historical lumber mill, warehousing, and equipment storage activities. Required deliverables include developing a Quality Assurance Project Plan (QAPP), Sampling and Analysis Plan (SAP), conducting soil and groundwater sampling, evaluating remediation alternatives, and creating a corrective action plan. Consultants must engage stakeholders and coordinate with regulatory agencies such as the Oregon Department of Environmental Quality (ODEQ) and EPA. Key procurement dates include a mandatory site walk on April 10, 2025, proposal submission deadline of May 2, 2025, proposal evaluation completion by May 16, 2025, award notification on May 28, 2025, and a project kickoff meeting on June 10, 2025. Potential environmental issues to be addressed include petroleum contamination, potential PCB-containing transformers, and site-specific drainage and fill material concerns.

The solicitation does not explicitly specify set-aside designations or restrictions on responding organizations. The Phase I Environmental Site Assessment will be exclusively provided to consultants attending the mandatory site walk, which may limit participation for firms unable to attend. The project involves a closed RCRA-designated wood waste landfill, suggesting potential complexity in environmental remediation requirements. While specific budget ranges are not disclosed in the provided documentation, the comprehensive nature of the project—involving detailed site investigation, stakeholder engagement, and regulatory coordination—implies a substantial investment in environmental assessment and potential remediation efforts. The project's location in Lincoln County and involvement of the Confederated Tribes of Siletz Indians suggest potential opportunities for local or tribal business engagement, though no specific procurement preferences are outlined in the available information.
