Portable Engines

Internal combustion engines are used to power a variety of portable equipment categories

Internal combustion engines are used to power a variety of portable equipment categories, including, but not limited to:

  • well drilling

  • barges

  • diesel pile-driving hammers

  • pumps

  • service or work-over rigs

  • cranes

  • welders

  • compressors

  • dredges

  • power generation 

  • tactical support equipment (TSE)

  • wood chippers

Generally, portable engines with a brake horsepower rating of 50 HP or more can be operated within the jurisdiction of the South Coast Air Quality Management District provided a South Coast AQMD Permit to Operate or PERP Registration has been issued for the equipment.  

The exceptions to this rule include:

  • a limited number of portable engine categories that are ineligible for PERP Registration; and

  • an even smaller category (Tier 0 engines) that cannot participate in either PERP or South Coast AQMD's permitting program.

Arranged Inspections

Unlike portable equipment units, portable engines registered under the PERP program require a fee, paid in advance, for South Coast AQMD to conduct an arranged inspection once every 3 years.

What's New!

Recently, there were revisions made to the PERP Regulation and Portable Engine 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 (PDF) containing a summary of the changes was mailed to all holders of PERP registration. En Espanol Aqui (PDF).
