What is the purpose of the Annual ID Number Verification Questionnaire?
Anyone who generates, transports, offers for transport, treats, stores, or disposes of hazardous waste must have a hazardous waste identification (ID) number, which is used to identify the hazardous waste handler and track the hazardous waste from the point of origin to its final disposal ("cradle to grave"). The purpose of this verification is to ensure that the information on record for the ID Number is correct and current.
The annual Verification Questionnaire for hazardous waste ID numbers and hazardous waste manifests is required by Health & Safety Code section 25205.16. Any generator, transporter, or facility operator who fails to provide the information required by the department to verify the accuracy of hazardous waste activity data shall be subject to suspension of any identification numbers assigned and to any other enforcement action (Health & Safety Code section 25205.16(c)).
No Fees Paid to DTSC in the Verification Questionnaire
In Step 9 Summary and Certification of the Verification Questionnaire, if there is a total in the Total Tonnage Subject to the G&H Fee Calculation line, it is only an estimate based on the information in your questionnaire. There may be further considerations that affect your G&H Fee liability. The California Department of Tax and Fee Administration (CDTFA) collects the G&H Fee. The G&H Fee imposes a flat rate per ton or fraction of a ton on manifested and unmanifested hazardous wastes. Sites that generate five or more tons of hazardous waste in a year must pay a fee. To pay the fee, they must register for an account, and then file a return with the CDTFA on their website.
For more information on the G&H Fee, visit CDTFA's Hazardous Waste Generation and Handling Fee page and DTSC's Generation and Handling Fee page or contact fees@dtsc.ca.gov or the CDTFA at (800) 400-7115.
