California Identification (ID) Numbers

An ID number identifies each handler of hazardous waste.  See DTSC’s EPA Identification Numbers fact sheet for general information and answers to the most common questions about ID Numbers.

Most generators, transporters and disposal facilities need an ID number to handle, store and/or treat hazardous waste.

Some businesses that generate and handle universal waste and businesses that generate less than 100kg per month of photographic waste containing silver are exempt from having an ID number.

California Permanent ID Numbers
Businesses that generate waste on an ongoing basis must have a permanent ID number.  To get a permanent ID number, you need to complete the required application, DTSC Form 1358.  There is no fee to obtain a permanent ID number.  Remember, if 5 or more tons of hazardous waste will be generated in a calendar year on your permanent ID number, generator fees may be due.  Go to www.boe.ca.gov/pdf/boe400-efa.pdf

Federal (RCRA) ID Numbers
Waste regulated by the federal government under the Resource Conservation and Recovery Act is known as "RCRA waste." If a business generates more than 1 kilogram of RCRA acutely hazardous waste per month or more than 100 kilograms of other RCRA waste per month, they must have a federal ID number that is issued by U.S. EPA.  Remember, if 5 or more tons of hazardous waste will be generated in a calendar year on your federal ID number, generator fees may be due.  Go to www.boe.ca.gov/pdf/boe400-efa.pdf

If you generate 5 or more tons of hazardous waste in a calendar year regardless of the final disposition of the waste on an type of ID number, California permanent or temporary; or federal permanent or temporary, you must contact the Board of Equalization to obtain a generator fee account number.   Please contact the Board of Equalization if you have any questions regarding the requirements of registering, at http://www.boe.ca.gov/pdf/boe400-efa.pdf or at (916) 323-9555

DTSC sends out a verification questionnaire to businesses holding permanent federal or California ID numbers.  Businesses are required to respond with any updates to their business information.  Failure to respond to the verification questionnaire will lead to inactivation of the ID number.  An ID Number Verification Fee and Manifest Fee assessment is included with the verification questionnaire.  Fees are assessed for holders of ID Numbers. Questionnaires are mailed annually.  Additional fee information is available in the Hazardous Waste Fee Summary.
