Hazardous Waste Removal

Hazardous waste removal task is part of the Hazardous Waste program on Complyrs.

Hazardous Waste ICON Removal


There are limits on how long hazardous waste can only be stored at a facility. Hazardous waste can only be removed from a generation site by an approved Hazardous Waste Transporter. The transporter must provide the facility with a Hazardous Waste Manifest or a Bill of Lading when hazardous waste is removed from the site.

Large Quantity Generator- More than 1000 kg

If a facility generates more than 1000 kg of hazardous waste in any calendar month, it is considered a Large Quantity Generator (LQG) and the waste must be removed within 90 days of the “accumulation start date” recorded on the waste label.

Small Quantity Generator- Less than 1000kg

If a facility generates less than 1000 kg of hazardous waste in any given calendar month, it is considered a Small Quantity Generator (SQG) and waste can be maintained on-site for up to 180 days from the “accumulation start” date.

Conditionally Exempt Small Quantity Generator- Less than 100 kg

Facilities that generate less than 100 kg of hazardous waste may be considered Conditionally Exempt Small Quantity Generators (CESQG) and have even greater latitude in waste storage duration and other requirements.

Manifesting and Bills of Lading

Hazardous waste transporters must provide documentation that waste has been removed from a facility. Usually the documentation is a Uniform Hazardous Waste Manifest. If the waste is being consolidated by the transporter, a bill of lading can be used. The bill of lading must include the hazardous waste manifest number the transporter is using to document the legal transport and disposal of hazardous waste.

Hazardous waste manifests are essentially a “Chain-of-Custody” document that track the generation, transportation and disposal of hazardous waste from cradle to grave. Hazardous waste manifests and bills of lading for hazardous waste disposal should be retained indefinitely. In addition, hazardous waste generators in California must make an additional copy of the “Generator’s” copy of the hazardous waste manifest and send it to the DTSC. The mailing address is:

DTSC Generator Manifests

P.O. Box 400

Sacramento, CA 95812-0400

Bills of lading do not need to be sent to the DTSC.
