Description

The California Department of Transportation (Caltrans) is seeking a qualified contractor to provide hazardous waste disposal services across eight northern California counties. The contract requires on‑call collection, transport, and disposal or recycling of a wide range of hazardous materials—including industrial, laboratory, medical, and organic waste—while complying with federal, state, and local regulations. The contractor must supply licensed personnel, appropriate trucks and equipment, packaging materials, and may need to subcontract ELAP‑certified laboratory analysis. Small‑business and Disabled Veteran Business Enterprise preferences are available, and prevailing‑wage rules apply for contracts exceeding $15,000. • Core services: on‑call pickup, transport, disposal/recycling of hazardous waste streams (paints, solvents, batteries, medical waste, etc.) in Siskiyou, Modoc, Plumas, Tehama, Lassen, Trinity, Shasta, and Butte counties. • Mandatory certifications: Class A General Engineering license, HAZ hazardous‑substance removal certification, motor‑carrier permit, multiple hazardous‑material transport registrations, and ELAP‑certified lab subcontractor (if lab work is performed). • Contract terms: Estimated start Dec 1 2026, end Nov 30 2029 (≈3 years), with quarterly reporting, strict invoice documentation, and insurance requirements; small‑business/DVBE incentives up to $150 k total.

Budget estimate

$10,000,000 – $30,000,000

No contract ceiling is disclosed, but based on the scope (hazardous‑waste services for eight counties over three years) a typical market rate ranges from $10 million to $30 million. The estimate considers per‑ton disposal fees, equipment operation costs, labor (including prevailing‑wage rates), and the extensive regulatory compliance burden. Small‑business incentives are modest relative to the total contract value.
