Portable Equipment Registration

Owners and operators of portable engines (>50HP) and portable equipment can register their units under the California Air Resources Board (CARB) Statewide Portable Equipment Registration Program (PERP) in order to legally operate their equipment throughout California without having to obtain individual permits from local air districts.  As an alternative to the State PERP program, the District offers a local registration program for portable engines and portable equipment operated solely in Butte County.

Airborne Toxic Control Measure (ATCM)Рfor Diesel Particulate Matter from Portable Engines Rated at 50 Horsepower and Greater  (amended 11/30/18).  This regulation is applicable to both State and local registration programs.
