We reiterate here that this is a DIESEL Regulation. All Non-Diesel vehicles are currently exempt from regulation requirements.

The regulation exempts non-diesel trucks and trucks less than 14,000 lb. GVWR. Light Duty Diesel Trucks are classified as those between 14,001 and 26,000 lb. GVWR, and Heavier Diesel trucks are classified as those over 26,001 lb. GVWR.

Portable Power

YOUR PORTABLE POWER CHECKLIST

By way of background, portable equipment 50 horsepower and greater requires a permit from the local air district in which the unit is operating. To lessen the burden (and costs) of reporting in multiple air districts throughout the state, CARB established the Portable Equipment Registration Program (PERP), which enables fleet owners to acquire a statewide portable equipment permit for qualifying portable units. Note that this is a Voluntary Program, and, as such, may set rules and standards independent of local air district rules.
