PERP Application, Record Keeping & Reporting Forms
Effective November 30, 2018, PERP initiated implementation of an invoicing process in which applicants will be requested to submit all PERP applications without fees. Once the application is deemed complete, the applicant will receive an invoice detailing the fees required to process the application. These fees will not, generally, be refundable.
Please mail your PERP applications and other program correspondence to the address below. Applications sent to the general CARB PO Box, or via FedEx, UPS, or by other means will delay processing.
Faxed, emailed, and hand-delivered applications are not accepted.
