Hazardous Waste ID Number Verification Questionnaire

General Questions

Q. Does my company need to complete the 2019 Verification Questionnaire?

A. Your company is required to complete the 2019 Verification Questionnaire if you meet one or both of the following criteria:

  • Your hazardous waste EPA ID number was active any time during the 2018/2019 fiscal year from July 1, 2018 – June 30, 2019.
  • Your company manifested hazardous waste using an assigned hazardous waste EPA ID number during the 2018 calendar year from January 1, 2018 – December 31, 2018.
Q. Does DTSC mail paper Verification Questionnaires?

A.  One of the reasons DTSC has created the electronic Verification Questionnaire (eVQ) system was to reduce our carbon footprint, so we will not be mailing hard copies of the Verification Questionnaires. If you do not have internet or computer access and/or need assistance with completing the electronic Verification Questionnaire please call us at 1-800-618-6942 for assistance. Our telephone hours are Monday to Friday from 9:00am to 4:00pm.

Q. How will I be notified when the 2019 VQ cycle begins?

A. When the 2019 Verification Questionnaire cycle begins, you will be notified in one of the following ways.

  • By email. An initial email notification will be sent, followed by subsequent reminder emails. The email notifications will be sent to the primary and alternate contacts’ emails associated with the eVQ account. For handlers completing the VQ for the first time, the email notification will be sent to the site contact’s email associated with the EPA ID number. Please add eVQ@dtsc.ca.gov to your safe senders list to ensure that you will receive the email notices.
  • By mail. For EPA ID numbers that do not have an email associated with it, a paper notification will be mailed to the mailing address associated with the EPA ID number.
Q. When is the deadline to complete the 2019 VQ?

A. The deadline to complete the 2019 VQ is 30 days from the date you have received the notification from DTSC.

Q. What happens if I do not complete the 2019 VQ by the deadline date?

A. Failure to complete the 2019 VQ by the deadline date constitutes as failure to comply with the California Health and Safety Code sections 25205.15 and 25205.16; as a result, DTSC will inactivate your EPA ID number.

Q. How do I complete the Verification Questionnaire?

A. To complete the Verification Questionnaire, go to the eVQ home page at eVQ.dtsc.ca.gov. If you have an existing eVQ account proceed with logging in to access your Verification Questionnaire. If you do not have an account, create an account first then log in. For guidance on how to complete the questionnaire, please download the VQ User Guide.

Q. Do generators have to complete the Verification Questionnaire every year?

A. Generators with hazardous waste EPA ID numbers that were active anytime during the previous fiscal year from July 1 – June 30 or manifested hazardous waste using an assigned hazardous waste EPA ID number during the previous calendar year from January 1 – December 31 will need to complete that respective year’s VQ.

Q. Am I required to complete the 2019 VQ if I had a temporary EPA ID number in 2018?
  1. You or your company are/is exempt from reporting a temporary EPA ID number in the annual Verification Questionnaire if you or your company meet one of the following conditions:
  • You are a homeowner with a one-time cleanup of hazardous waste with less than four uniform hazardous waste manifests reported in the 2018 calendar year.
  • Your company did not have a permanent EPA ID number during the required reporting period of July 1, 2018 – June 30, 2019 and zero uniform hazardous waste manifests were reported on the temporary ID number.
  • Your company had only one temporary EPA ID number with less than four manifests reported in the 2018 calendar year and less than 100 employees.
Q. Why did I receive a notification to complete the 2019 VQ when my business was closed in 2018?

A. Although your business was closed in 2018, you have received a notification to complete the 2019 VQ because your hazardous waste EPA ID number was active sometime during the 2018/2019 fiscal year from July 1, 2018 – June 30, 2019 or your company manifested hazardous waste using an assigned hazardous waste EPA ID number during the 2018 calendar year from January 1 – December 31, 2018.

Please note that your EPA ID number does not automatically inactivate when your business closes. Your EPA ID number is still active if you did not officially inactivate your EPA ID number with DTSC. When the 2019 Verification Questionnaire cycle opens you can inactivate your EPA ID number in step 3. If the 2019 VQ is closed, you will need to inactivate your EPA ID number by completing the appropriate form, DTSC Form 1358 if you have a permanent State EPA ID number or EPA Form 8700-12 if you have a federal EPA ID number.

If you have already inactivated your EPA ID number when your business closed in 2018, you are still required to complete the 2019 Verification Questionnaire. Completing the 2019 Verification Questionnaire will not reactivate your EPA ID number if you want to keep the number in inactive status.

Q. How can I check the status of an ID number?

A. To check the status of your ID number please search for your ID number using one of the following options:

By ID Number | View

By Company | View

Q. Who can I contact with questions concerning hazardous waste management, site cleanup, and other DTSC regulatory information?

A. DTSC’s Regulatory Assistance Office (RAO) responds to inquiries from the regulated community, environmental firms, other agencies, and the public at large about departmental issues. Regulatory Assistance Officers can be reached at RAO@dtsc.ca.gov or by calling (800) 728-6942 (within California) or (916) 324-2439 (if calling from out-of-state).

This includes recycled waste, treated wood waste, and waste sent outside California for disposal.

Q. I have an EPA ID number that is inactive. Why is it inactive?

A. Your EPA ID number may have been inactivated due to, but not limited to the following reasons:

  • DTSC may have inactivated your EPA ID number because you failed to comply with the California Health and Safety Code sections 25015 and 25205.16 and did not complete the Verification Questionnaire.
  • Someone from your company requested to inactivate your EPA ID number.
  • Your EPA ID number was inactivated because of procedural violations.
