WHAT IS THE PURPOSE OF THE ANNUAL EPA ID NUMBER VERIFICATION QUESTIONNAIRE?
Generators, transporters, and facilities who are authorized to store, transport, treat, and dispose of
hazardous waste are required by law to annually verify their EPA ID Number information per Health & Safety
Code section 25205.16(b). The purpose of this annual verification is to ensure that the information on record
for the EPA ID Number is correct and current.
In approximately June of each year, the Department of Toxic Substances Control mails the EPA ID Number
Verification Questionnaire forms to EPA ID Number holders who have active status or who have had their
EPA ID Number used on a manifest during the prior calendar year. The Verification Questionnaire Package
also includes a Schedule A fee form for the calculation of manifest fees owed and a Schedule B fee form
to calculate total EPA ID Number verification and manifest fees owed.
Any generator, transporter, or facility operator who fails to return the Verification Questionnaire forms
shall be subject to suspension of any and all identification numbers and to any other enforcement action
(Health & Safety Code section 25205.16(c)).
