How To Get Into PERP

The Statewide Portable Equipment Registration Program (PERP), established in 1997, has emission standards that engines must satisfy. As a consequence all portable engines are not automatically eligible for registration. Certified engines which have been tested by the U.S. EPA or the ARB and meet the federal off-road engine emission standards are eligible for the PERP. Older engines that do not meet the most stringent California emissions standards but have still been issued emission certifications have been designated as Tier 1 and 2 engines.

Due to emergency amendments adopted by the Air Resources Board (ARB), Tier 1 and 2 engines have again been given the opportunity to register in PERP for a limited time (as long as they meet the residency requirements). In order to meet the residency requirements an engine must have operated in California between March 1, 2004 and October 1, 2006. This opportunity to register Tier 1 and 2 engines will end on December 31, 2009.

Owners of portable engines and equipment wishing to register in PERP should visit the ARB online and download and fill out the necessary forms with all the required information. All PERP forms are available online ARB’s website.

Notification Requirements

If you own, operate, or rent a registered portable equipment unit (not engine) and plan to operate it in a district for more than five days than you must notify that district within two days of commencing operations. Notification can be made via facsimile, electronic mail, in writing, or by telephone, and should include the following information:

PERP Registration Number
Contact Person
Contact Number
Location Equipment Will Be Used
Date of Equipment Arrival
Estimated Duration of Equipment Use (In Days)

If it is unknown that operation of the equipment unit would warrant the need to notify the district, then notifications must be made within 12 hours of determining the need to operate more than five days in a single location.

Reporting and Recordkeeping

If you own a registered portable equipment unit or engine, the PERP requires records to be maintained of the operation of each registered engine and equipment unit. Effective April 27, 2007 recordkeeping for all engines not previously required to maintain records are now required to do so.

All records shall be maintained at a central place of business for five years and shall be made available to the districts upon request.

The list of items required to be maintained please refer to the PERP Regulation under Record Keeping Requirements.
