Colorado's manifest requirements
- Use either a printed or e-manifest uniform hazardous waste manifest form.
- Handlers of hazardous waste can print and distribute forms from any source that’s registered with the U.S. EPA.
- We don’t require copies of hazardous waste manifests be submitted to us unless we specifically requested them (for example, as follow-up to a hazardous waste inspection).
State-specific waste codes
- The only state-specific waste codes for Colorado are related to waste chemical weapons, including:
- Mustard gas.
Associated treatment residues and contaminated materials that came in contact with chemical weapons.
