Electronic Verification Questionnaire (eVQ) System

PLEASE NOTE: The electronic Verification Questionnaire (eVQ) is for the annual verification process only. The system is now closed to access. You will be able to log into the system for the 2014 Verification cycle approximately the first week in June. If you currently have an eVQ account, you do not need to establish a new one for 2014. We will notify eVQ users in June when access to the 2014 eVQ is available. To make sure that you receive the email notification, please add eVQ@dtsc.ca.gov to your list of "safe senders". Note for the 2013 Verification cycle: Access to the 2013 Verification is now closed. EPA ID Numbers without a 2013 Verification submission were inactivated. You can check the status of your EPA ID Number at www.hwts.dtsc.ca.gov, "Reports", Report #3. If you need to reactivate your EPA ID Number, submit a DTSC Form 1358. You can access the form at http://www.dtsc.ca.gov/HazardousWaste/upload/GISS_-FORM_1358.pdf.

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)).
