EPA ID Numbers, Manifests and Fees

DTSC is briefly delaying the annual mailing of the 2008 Verification Questionnaire and Fees Assessment, in an effort to improve the quality of our customer service and increase the efficiency of our operations. DTSC is simplifying the documentation and streamlining the fee processing in an effort to reduce costs and provide improved service to our EPA ID and manifest fee payers. The verification questionnaire and fee assessments are typically mailed in early June, but the process improvement efforts have delayed the mailing until late summer or early fall.  If you have questions, you may contact our Telephone Information Center at (800) 618-6942.

To apply for, reactivate, or inactivate a permanent California identification number, submit DTSC Form 1358.

Persons who generate, transport or offer for transport, treat, store, or dispose of hazardous waste generally must have an Identification (ID) Number, which is used to identify the hazardous waste handler and to track the waste from its point of origin to its final disposal ("From Cradle to Grave").

Most hazardous waste falls into two types in California: waste regulated by the federal government under the Resource Conservation and Recovery Act is known as "RCRA waste"; waste regulated by California law alone is known as "non-RCRA" or "California-only" waste.  All hazardous waste in (RCRA and non-RCRA) California is regulated under state statutes and regulations.  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.  If the business generates 100 kilograms or less of RCRA waste or one kilogram or less per month of acutely hazardous waste, and meet certain other requirements, they are exempt from having a federal ID number.  These businesses are called conditionally exempt small-quantity generators or CESQGs.

DTSC issues ID Numbers for generators, transporters, and treatment, storage, and disposal facilities that handle hazardous wastes not regulated under RCRA. As stated above, this depends on the type of waste that you generate and the rate at which you generate it.  U.S. EPA issues federal (RCRA) ID Numbers.  If you need a California ID Number, you can find more information on our California ID Number page. 

The law requires that most hazardous waste be transported from hazardous waste generators to permitted recycling, treatment, storage, or disposal facilities (TSDF) by registered hazardous waste transporters, and that each shipment be accompanied by a hazardous waste manifest. The manifest is the document that provides information for “cradle-to-grave” tracking of the hazardous waste.  Learn more about Hazardous Waste Manifests.
