Portable Equipment Registration Program (PERP)

PERP is a statewide program created by the California Air Resources Board (CARB) to register portable equipment and engines designed to move from one location to another throughout California. CARB issues the PERP registrations, and the Sac Metro Air District (District) enforces the program's requirements in Sacramento County. For more information on how to apply for a PERP registration, fees, and other requirements, please visit CARB's PERP website.
​

For more information on how to operate under the PERP program, watch the presentation hosted by the Clean Air Partnership Technical Advisory Committee ​​below:
