STEP 5: User authentication email.

After EPA has reviewed and approved the forms, you will receive an email from the CDX Helpdesk ( The content of this email depends on the type of user.

New users will receive instructions for receiving your Customer Retrieval Key (CRK). You will use your CRK to complete your EV-CIS account registration.

Existing users that are adding new roles (e.g., CROMERR Signer) will be notified that the additional role has been added.

STEP 6: Account finalization.

This step also looks slightly different, depending on the user.

New users will login to CDX using the URL provided in the authorization email.

They will input the CRK provided in the Help Desk phone call, as well as other information. This step must be completed  before the user can access their account.

New or existing users that are adding the "CROMERR Signer" role will establish security questions/answers that will be used during the certificate request process.
