Getting Started: New CERS Application!

  1. Complete & submit the CERS Application Form
  2. 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.
  3. 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 more about permission levels.

Your CERS account will tell you which documents to upload based on your business activities and permit requirements. Many of our forms are no longer accepted in paper format. Please view our HMD Forms page for a list of required forms, templates, and submission requirement information.
