California Environmental Reporting System (CERS)

As of 2013, all businesses in California that are subject to one of the hazardous materials or hazardous waste programs are required to report all documentation electronically in the California Environmental Reporting System (CERS).

Businesses submitting in CERS for the first time must designate a lead user and create an account. The lead user is someone authorized to review, edit and submit all CUPA regulatory documents on behalf of your business. To create an account, log into the CERS Central Business portal and “create a new account”.

Editing, reviewing and submitting documents in CERS:

Ensure each element of your submittal is complete, all required documents are uploaded and all programs are reported. All sections of CERS will remain in draft until it is “submitted” by the lead user. When documents are in draft form, only the business can see them. Submitted documents will be reviewed by Ventura County Environmental Health Division. If a section of the submittal is “not approved”, an email will be sent to the lead user detailing the required corrections. The corrections are required to be completed and resubmitted within 30 days.


Business are required to:

  • Electronically review and certify the CERS submittal at least 1 time per calendar year, no later than 12/31.

  • Update the CERS submittal within 30 days of any significant changes to the business or inventory.

  • Ensure all required documentation is available for review on-site (electronic or paper).

Multi-jurisdictional businesses may establish an organization in CERS with approval from Cal EPA.
