Owners or operators of portable engines and certain other types of equipment can register their units under the Air Resources Board's (ARB) Statewide Portable Equipment Registration Program (PERP) in order to operate their equipment throughout California without having to obtain individual permits from local air districts. The following is provided to help you complete the registration process.

NOTICE:  Effective immediately, PERP will no longer accept applications and renewal invoice payments via fax due to security issues with credit card numbers transmitted by this method.  Please mail them directly to the address listed on the application form and renewal invoice.

NEW REQUIREMENTS

Recently, there were revisions made to the PERP Regulation and Portable Engine Airborne Toxic Control Measure (ATCM).  These revisions became effective on February 19, 2011, and all holders of PERP Registrations are now subject to the new requirements.  Updated operating conditions reflecting the new requirements will be issued upon renewal for all existing registrations. A flyer containing a summary of the changes will be mailed to all holders of PERP registration. En Espanol Aqui.

CRITICAL REGISTRATION REQUIREMENTS

For 2012, engine manufacturers are required to produce engines in all power categories that are certified to the Interim Tier 4 level. Engines that were produced under the "flex" provisions of either 40 CFR part 89.102 or 1039.625 will continue to be eligible for initial registration in PERP.

Pursuant to sections 93116.3(b)(2)(B) and 93116.3.1 of the Portable Engine ATCM, ARB will accept initial registration applications for non-flex Tier 3 engines rated at 75 to 750 bhp and also non-flex Tier 2 engines rated over 750 bhp only until June 30, 2012.

On July 1, 2012 to apply for initial registration in PERP, all non-flex diesel engines rated 50 bhp and above must be certified to the interim Tier 4 emission standard.

The fleet standards from the Portable Engine ATCM take effect January 1, 2013. Please see our flyer about this requirement:  New Fleet Requirements Flyer.

PERP Advisory

Effective September 1, 2011, the Air Resources Board will no longer accept applications for initial registration of Tier 1 and/or Tier 2 engines that were originally submitted on or before December 31, 2009 and subsequently returned due to insufficient information. If you are currently in possession of an application for these engines that was date stamped by the ARB, then it must be re-submitted no later than August 31, 2011.
