Hazardous Waste ID Numbers
DTSC issues ID numbers to generators, transporters and disposal facilities. This includes EPA ID numbers, and State ID numbers for non-RCRA hazardous waste. Temporary ID numbers are issued to people or businesses who do not typically generate hazardous waste. These ID numbers are valid for 90 days. Permanent ID numbers are issued to people or businesses who routinely generate hazardous wastes.
There is no fee to obtain an ID number.
PLEASE NOTE: Processing times for both EPA ID and State ID numbers may take up to 15 WORKING days from the date we verify your application is complete. Failure to provide a complete application may delay the issuance of your ID number.

HOW DO I OBTAIN A HAZARDOUS WASTE ID NUMBER?
If you know which type (Temporary or Permanent) of number you need, click on one of the following buttons. Below these buttons, you will find some additional information on who needs a hazardous waste ID number. If you do not know which category of number you need, read the rest of this web page for more information.
Anyone who generates, transports, offers for transport, treats, stores, or disposes of hazardous waste (All are collectively called "handlers".) generally must have an ID number, which is used to identify the hazardous waste handler, and to track the hazardous waste from the point of origin to its final disposal (Also known as "From Cradle to Grave".). State ID numbers are owner and site specific. EPA ID numbers are site specific. The ID number is placed on the manifest for each generator, transporter, and facility that handles the waste.
CATEGORIES OF HAZARDOUS WASTE ID NUMBERS
Temporary and Permanent ID numbers are also divided into two categories of ID numbers, called EPA ID numbers and State ID numbers. The category of ID number issued is dependent on the classification (RCRA hazardous waste or non-RCRA hazardous waste) and amount of hazardous waste generated/handled.
Generators who produce, in each month, less than or equal to 100 kilograms of RCRA hazardous waste that is hazardous only due to silver, such as spent photo-processing solutions, do not need an ID Number. This exemption does not apply if the generator produces any other hazardous waste or is otherwise required to get an ID Number.
