Statewide Portable Equipment Registration Program (PERP)

PERP Overview

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.

 

Registration Requirements

To register in PERP, all engines must meet the following tier levels:

  • Engines rated 50 to 75 bhp:  Interim Tier 4.
  • Engines rated 75 to 750 bhp:  Tier 3.
  • Engines rated over 750 bhp and over: Tier 2.

Beginning January 1, 2011, engine manufacturers are required to produce engines in the 175 to 750 bhp category that are certified to the Interim Tier 4 level. PERP will continue to register the previous tier engines for six months beyond this date -- until June 30, 2011.  On July 1, 2011, to register in PERP, all engines must meet the following tier levels:

  • Engines rated 50 to 75 bhp: Interim Tier 4.
  • Engines rated 75 to 175 bhp: Tier 3.
  • Engines rated 175 bhp and over: Interim Tier 4.
 

District Notification

You Must Notify EKAPCD if portable equipment unit will be residing in District for more than five days. According to Section 2459 of the PERP regulation, the owner or operator or renter shall notify the district in writing, via facsimile, or by telephone, within 2 working days of commencing operations in that district. The 5-day trigger starts when the equipment unit is brought onto the location, not when it starts to operate.
