Instructions for Submitting Applications via Email

The Portable Equipment Registration Program (PERP) now accepts all registration applications and reports via email at: PERPapplications@arb.ca.gov. Follow the instructions below to ensure prompt application processing; failure to follow the instructions will result in delays.

• All applications require current forms downloaded from the Application Forms webpage.  Forms are updated periodically. Ensure you have the most up-to-date forms to prevent any delays in application processing by downloading current forms.
• Submit only one company account per email. This will ensure equipment is registered to the correct account. Accounts are based on both mailing and street addresses. If you have multiple accounts or are unsure, please contact portable@arb.ca.gov. 
• Include Form 1 with Form Numbers 2 to 15. Only one Form 1 is required per email as units will be registered for one company account.
• There will be a limit of five (5) units with supporting documentation per emailed request. This limit avoids size-related undeliverable emails.
• If submitting multiple units, all units must be the same unit type. Each form number is a different unit type. If unsure of which form to use, please contact portable@arb.ca.gov.
• Rename forms and supporting documentation by the form number and serial number listed on the form. This will allow PERP staff to organize and combine your application quickly and accurately, especially if submitting multiple units.
  • Examples:
    • Form 1: Form 1_Company Information
    • Form 2: Form 2_AB1234C123456
    • Photos: Form 2_AB1234C123456_Photo1 and Form 2_AB1234C123456_Photo2
    • Documentation: Form 2_AB1234C123456_Doc1 and Form 2_AB1234C123456_Doc2
• Email completed and signed application forms and associated photos, documents, flow diagrams, and compliance reports to: PERPapplications@arb.ca.gov.

Note: For registrations being renewed, you may submit modification, correction, placard replacement, and/or company update forms with your renewal invoice to: PERPrenewals@arb.ca.gov. This will ensure processing of both requests at the same time.

When PERP receives your application,you will receive a response within 30 days. Please contact PERP staff at portable@arb.ca.gov if you do not receive a billing invoice or staff follow-up within 30 days. Per the PERP Regulation, PERP has 90 days to issue registration once the application is deemed complete and registration fees are paid.
