Hazardous Waste ID Number

You will need a Hazardous Waste ID number before you contact us to schedule an appointment. The exception is for electronic waste, household batteries, fluorescent bulbs, and latex paint, which do not require an ID number.

The Hazardous Waste ID Number, issued by the California Department of Toxic Substance Control (DTSC), identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID Number enables regulators to track waste from its origin to final disposal (“cradle to grave”). For more information, visit DTSC’s Hazardous Waste Generators page .

Which ID number do you need?

Temporary Hazardous Waste Number: If your business generates hazardous waste only once or twice a year, you may want to apply for a Temporary Hazardous Waste Number.

Permanent Hazardous Waste Number: If your business generates hazardous waste monthly, you need to apply for a Permanent Hazardous Waste Number. This process can take up to 15 business days and is necessary for businesses that regularly drop off hazardous waste at our facility.
