Regulations/Programs Regarding
bullet Verification Program The ARB adopted the "verification" procedures for diesel emission control strategies (DECS) to ensure real emission reductions, along with ensuring DECS durability and compatibility with various engines and applications.
   
This table lists the current technologies or DECS which have been "verified" by the ARB.
   
bullet On-Road New Vehicle & Engine Certification Program ARB is responsible for the certification and production audit of new passenger cars (PC), light-duty trucks (LDT), medium-duty vehicles (MDV), heavy-duty engines (HDE) and vehicles (HDV) including urban buses (UB), on- and off-road motorcycles (ONMC and OFMC), all-terrain vehicles (ATV), and electric golf carts (eGC). Vehicles and engines are not legal for sale in California until certified by ARB to meet California's vehicle and engine exhaust emission standards.
   
Once a vehicle or engine is certified to meet California's vehicle and engine exhaust emission standards, an executive order is issued by the ARB.
   
bullet image Mobile Source In-Use Fleet Rules The Heavy-Duty Diesel In-Use Strategies Program develops and implements strategies to significantly reduce emissions from all existing on- and off-road diesel engines, with a special emphasis on reducing diesel particulate emissions.
   
The Fleet Rule for Transit Agencies requires fleetwide NOx and PM reductions and more stringent engine emission standards for new urban buses.
The Fleet Rule for Solid Waste Collection Vehicles mandates the use of "BACT" on waste collection vehicles to reduce diesel PM emissions by specified implementation dates.
The Fleet Rule for Public Agencies and Utilities mandates municipal and utility vehicle owners to reduce diesel PM emissions from their affected vehicles by specified implementation dates.
The ARB is developing a control measure to reduce diesel PM emissions from in-use (existing) off-road mobile equipment in California. Such equipment is used in construction, mining, and industrial operations.
   
The ARB is developing a control measure to reduce diesel PM emissions from private fleets of on-road heavy-duty diesel-fueled vehicles operated in California.
   
bullets Grant Programs  
The Carl Moyer Memorial Air Quality Standards Attainment Program provides incentive grants for cleaner-than-required engines and equipment.
   
The Lower-Emission School Bus Program provides grant funds to replace or clean-up dirtier school buses in California.
   
bullet Diesel Risk Reduction Plan
The ARB adopted the Diesel Risk Reduction Plan in response to the August 1998 identification diesel-fueled engine exhaust (diesel PM) as a toxic air contaminant (TACs). This Plan identifies specific statewide regulations designed to reduce diesel PM emissions from diesel-fueled engines and vehicles in California.
