The Colorado Department of Public Health and Environment (CDPHE) is procuring hazardous waste removal services under a sole-source justification, with proposals due August 27, 2026. The intended awardee is Clean Harbors Environmental Services, Henderson, Colorado, under a five-year term from September 1, 2026 through August 31, 2031.

The sole-source determination rests on Clean Harbors being the only vendor in Colorado that owns and operates its own treatment, storage, and disposal facility (TSDF), a capability identified as critical and non-duplicable for safe, compliant hazardous waste disposal. The CDPHE Laboratory requires hazardous waste removal services including lab packing, 24-hour emergency response for spills, APHIS-regulated waste disposal, and cannabis product waste disposal, all subject to full EPA, DOT, and RCRA compliance. Clean Harbors holds hazardous waste permits, RCRA permits, TSDF permits, hazardous waste transportation permits, and APHIS permits.

The estimated contract value is $200,000 over five years. Pricing was determined fair and reasonable through comparison to established catalog prices and historical rates for similar services. The prior contractor, RCRA Waste Services, failed to meet contract obligations due to lacking a TSDF, which constrained laboratory operations and informed the justification for sole-source procurement with a vendor possessing in-state infrastructure.

The contract is advertised in both Denver County and Denver City jurisdictions.
