Information Sheet
Portable Equipment Registration Program

What is the Portable Equipment Registration Program?
The Portable Equipment Registration Program (PERP) is a voluntary statewide program to register portable equipment such as air compressors, generators, concrete pumps, tub grinders, wood chippers, water pumps, drill rigs, pile drivers, rock drills, abrasive blasters, aggregate screening and crushing plants, concrete batch plants, and welders. Portable equipment registered in PERP may operate throughout the state without obtaining permits from any of California's 35 air quality management or air pollution control districts (air districts).

Who is currently eligible for PERP?
For a limited time, owners and operators of older, dirtier certified engines may register in PERP. Uncertified engines (Tier 0) are not eligible to register in PERP. (However, at the discretion of the air pollution control officer, a local air pollution district may permit Tier 0 engines). The portable equipment must have resided in California between March 1, 2004 and October 1, 2006. This opportunity ends on December 31, 2009. Do not wait! Early applicants pay less!

How does this affect me?
If you own or operate a portable engine 50 horsepower or greater, you must have a permit or registration to legally operate in California. California has 35 local air districts that are responsible for taking enforcement action against individuals who own or operate portable equipment without a registration or permit. Recently, California air districts received a significant increase in funds for their enforcement activities. It is very likely that the owners and operators of unregistered or unpermitted engines will be cited and fined. Avoid being penalized! Register today!

What is included with my PERP registration?
PERP registrations are valid for three years and include a certificate and an identification plate that allows air district inspectors to easily determine from a distance that your equipment
is registered.

What does PERP registration cost?
PERP fees depend on whether or not your engine meets the current tier standard. Here is how to determine the tier level for your engine and the current tier standard.

• Fees for Tier 1 engines.
• Fees for Tier 2 engines that do not meet the current tier standard.
• Fees for engines that meet the current tier standard.
