To register an eVQ account follow these steps:

1. Go to the eVQ home page. Click the “Register” button.
2. Enter your ID number in the first field and click “Add”. An ID number is 12 characters long and begins with a lettered prefix of “CA.” There is no space between the lettered prefix and the numbers.
3. If the ID number you have entered is correct, the information associated with the ID number will populate in some of the fields on the registration form.
4. Complete all the required fields (indicated by a red asterisk).
5. When you have successfully registered for an account, you will receive an email confirmation.

Note: Registering an eVQ account does not mean you have filed the Verification Questionnaire. After you have registered your account, log into the eVQ System to file the Verification Questionnaire.

First, verify that you have entered the correct ID number. An ID number is 12 characters long and begins with a lettered prefix of “CA”. If you still see the error message after verifying your ID number entry, email eVQ@dtsc.ca.gov and include the ID number that you were trying to register and the error message.

You can have multiple ID numbers under one eVQ account provided that the ID numbers all share the same Federal Tax Identification Number (FEIN). If your ID numbers have different FEINs, you must create a separate eVQ account for each ID number with a different FEIN. Each account must have a unique username; however, all the accounts can use the same contact email address.

Send an email to eVQ@dtsc.ca.gov. In the email, provide all your account usernames and specify which account you would like to keep. Your ID numbers will be consolidated under that account, and the other accounts will be deactivated.

If your company has an eVQ account, you will not be able to register another eVQ account. However, you can update the account contact information and designate yourself as the new contact. Refer to the VQ User Guide for instructions.

A Federal Employer Identification Number (FEIN), also known as a Federal Tax Identification Number, is used to identify a business entity. Most businesses have a FEIN unless you are a sole proprietorship. If you do not have a FEIN, this field will be left blank. For more information on FEINs, visit the Internal Revenue Service website.

The North American Industry Classification System (NAICS) is the standard used by federal statistical agencies in classifying business establishments to collect, analyze, and publish statistical data related to the U.S. business economy. The NAICS Code is a two to six-digit code that describes your company’s primary business activity. If your company has more than one NAICS Code, enter the code that reflects your business or organization’s primary activity. If you do not know your NAICS Code, please visit census.gov/naics/ or naics.com.

Tp update this information, you will need to complete the appropriate form. Email eVQ@dtsc.ca.gov for assistance.

The California Department of Tax and Fee Administration (CDTFA) collects the Hazardous Waste Generation and Handling (G&H) Fee. The G&H Fee Account Number – also known as the CDTFA number –  is nine digits long with no letters, spaces, or dashes. The fee applies to each generator of hazardous waste at each generation site that generates five or more tons of hazardous waste within a calendar year. This includes recycled waste, treated wood waste, and waste sent outside of California for disposal. If the G&H Fee Account Number does not apply to you, leave this field blank. If you need a G&H Fee Account Number, visit CDTFA’s website or call (800) 400-7115 for more information.

To calculate the total number of employees, count the organization’s total number of California employees, not the total number of employees at a respective site generating hazardous waste.

In your eVQ account, you may add additional ID numbers in Step 3 by clicking the “Add ID” button. You can only add ID numbers that have the same Federal Employer Identification Number (FEIN) as the other ID number(s) currently in your account.

The manifested waste tonnage reflects what is listed in the Hazardous Waste Tracking System (HWTS) rounded to the nearest hundredth. Verify the tonnage against your records and correct the tonnage if needed. If there is a discrepancy, correct the manifest tonnage and then contact the Manifest Corrections help desk at manifestcorrections@dtsc.ca.gov. To obtain manifest information, click on the ID number to see a list of the manifest tracking number(s) that are in DTSC’s records.

In Step 4 of eVQ, you are only required to report and verify hazardous waste tracked on a Uniform Hazardous Waste Manifest that is reported under your/your company’s ID number. Consolidated hazardous waste is reported in Step 8 of eVQ.

You can find information about manifest corrections on DTSC’s Hazardous Waste Manifest Information web page. After completing the Verification Questionnaire, email manifestcorrections@dtsc.ca.gov for further instructions.

You will receive an email confirmation when your questionnaire has been successfully submitted. A common reason for an incomplete questionnaire is failing to click the button “Save and Flag as Completed” in Step 5 of the questionnaire. If this button is not clicked, the questionnaire will show as incomplete on DTSC’s end.

No. All fees will be calculated as $0 on your eVQ invoice. Senate Bill 158 eliminated the Verification Fee and the Manifest Fee, assessed according to H&SC section 25205.16. Please consult the California Department of Tax and Fee Administration (CDTFA) regarding your waste detail information such as the total tonnage subject to the G&H Fee if an estimate is provided.

The total tonnage subject to the G&H Fee is only an estimate based on the data provided in eVQ. There may be further considerations that affect your G&H Fee liability. Contact fees@dtsc.ca.gov or CDTFA at (800) 400-7115 for more information.

DTSC’s tax ID number is 68-0281381.

To make payments for a past Verification Questionnaire, use our online payment processing system. In the field that reads “Purpose of payment (reference)”, enter your VQ number (located on your invoice), to ensure that the payment will be applied to the correct invoice. If you have any fee-related questions, contact DTSC’s Accounting Unit at accounting@dtsc.ca.gov.

Yes. If the Verification Questionnaire cycle is open, log in to your eVQ account and complete steps 1 and 2 of the Verification Questionnaire. When you reach step 3, ID Number Overview, select the “Reactivate” check box and click the “Save Changes” button. Proceed with the remaining questions to complete the questionnaire. Your ID number will be reactivated within 1-3 business days. You can check your ID number status by visiting HWTS.

If the Verification Questionnaire cycle is closed you can reactivate your ID number by submitting the appropriate form.

• For permanent state ID numbers, submit DTSC Form 1358
• For permanent federal ID numbers, submit EPA Form 8700-12 through the RCRAInfo System (recommended) or by mail.

Avoid an ID Number Inactivation in 2024. If your hazardous waste ID number was active at any time during the 2023 calendar year (from January 1 –  December 31, 2023) and/or your company shipped hazardous waste using an assigned hazardous waste ID number during the 2023 calendar year (from January 1 – December 31, 2023), your company is required to file the 2024 eVQ by the deadline.

The most common reasons ID numbers are inactivated include:

• Failure to file the annual Verification Questionnaire, as required by California Health and Safety Code section 25205.16.
• Someone from the company requested that the ID number be inactivated.
• Procedural violations.
