What is the purpose of the Annual EPA 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 EPA ID Number is correct and current.

The annual Verification Questionnaire and fees assessment for hazardous waste ID numbers and hazardous waste manifests is required by Health & Safety Code section 25205.15 and 25205.16. Any generator, transporter, or facility operator who fails to provide information required by the department to verify the accuracy of hazardous waste activity data shall be subject to suspension of any and all identification numbers assigned and to any other enforcement action (Health & Safety Code section 25205.16(c)).
