PERP

Portable Equipment Registration Program (PERP)

NEW Portable Wood Chipper Permit Requirement Advisory (PDF) to Owners/ Operators of a wood chipper.  On May 5, 2017, the SCAQMD Governing Board adopted amendments to Rule 219, clarifying permit exemptions.

 

The Portable Equipment Registration ProgramLink to external website. (PERP) is a statewide program created by the California Air Resources Board (CARB) to register portable equipment as an alternative to securing permits from local air quality control districts. PERP registered equipment may operate throughout the state without obtaining permits to operate from any of California's 35 air quality management or air pollution control districts.

Generally portable engines over 50 hp and portable equipment units that emit particulate matter cannot be operated within the jurisdiction of the South Coast Air Quality Management District (AQMD) without either an AQMD Permit to Operate, or PERP Registration. In some cases, portable equipment may be ineligible for PERP registration, leaving the AQMD permit as the only option.

Whether registered under PERP or permitted by AQMD, the responsibility for inspection of portable equipment and enforcement of applicable clean air requirements resides with AQMD. 

AQMD Permit or PERP?

The most significant difference is that PERP allows the freedom to operate portable engines and portable equipment units anywhere in the state without the need to obtain separate permits from each air quality district. Highlights of each program are summarized in the table below.
