 Getting Started: How to Create a CERS Account
  1. Complete the CERS Access Form; be sure to have the business owner or main operator sign it. 
  2. Submit form to the Hazardous Materials Duty Desk via e-mail, mail or fax
  3. Once the form is processed, an email invitation will be sent to the two contacts on the form (the lead users) to create a CERS username and password.
  4. Both lead users will need to go to https://cers.calepa.ca.gov/ to log in, review, and submit the required forms that for their facility in CERS. 
Only lead users can add/remove additional users to the account. Once access is granted, the County of San Diego can no longer grant access to a CERS account so more than one lead user is recommended.  

Please refer to our User Permissions Guidance Document to learn how to add users and choose permission levels.
