Owners or operators of portable engines must also comply with CARB Air Toxic Control Measures and 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.
Air Toxic Control Measure (ATCM) for Diesel Particulate Matter from Portable Engines
The purpose of this airborne toxic control measure (ATCM) is to reduce diesel particulate matter (PM) emissions from portable diesel-fueled engines and portable engine-driven equipment units.
The Portable Engine Airborne Toxic Control Measure (ATCM) fleet standards went into effect on January 1, 2013. Owners of portable engines should have submitted a statement of compliance to the Air Resources Board by March 1, 2013. In addition, a summary that identifies each portable engine in the fleet and the associated emission rate (g/bhp-hr) must be included. For more information and to locate the statement of complianceand fleet summary forms go to Fleet Emission Calculators.
