Description

The California Department of Transportation (Caltrans) is seeking a qualified contractor to provide comprehensive hazardous‑waste disposal services across eight northern California counties. The work includes on‑call collection, packaging, transport, disposal, recycling, sampling, laboratory testing, manifesting, and detailed reporting for a broad range of hazardous and universal waste streams. All work must be performed by the contractor’s own resources—subcontracting is prohibited—and the contractor must hold a full set of state and federal licenses, permits, and insurance coverages. Bids are due September 10, 2026, with the contract expected to run for three years, approximately October 2026 through September 2029. • Scope covers pickup, transport, treatment, disposal and recycling of hazardous, regulated, universal, and medical waste (paints, solvents, fuels, batteries, lamps, medical sharps, etc.). • Contractor must provide all required equipment (hazard‑rated drums, trucks, pressure washers, PPE) and handle sampling, lab analysis (included in rates), and full documentation (manifests, weight receipts, spill diaries). • Must maintain numerous certifications (CSLB General Engineering, HAZ, Motor Carrier Permit, DOT hazardous‑materials registrations, etc.) and meet extensive insurance, safety‑training, and reporting requirements (certified payroll, DVBE/SB utilization reports).

Budget estimate

$6,000,000 – $12,000,000

No total contract value is disclosed, but the scope covers eight counties with extensive on‑call services, numerous waste streams, and a three‑year term. Similar Caltrans hazardous‑waste contracts for multi‑county service areas typically range between $2 million and $4 million per year, depending on waste volume and travel distances. Assuming an average mid‑range of $3 million annually, the total contract value would be roughly $9 million over three years. This estimate accounts for equipment, labor, disposal fees, transportation, and required reporting, but actual pricing could vary based on the bidder’s unit‑rate proposals and waste volume.
