RULES & REGULATIONS

The Rule for On-Road Heavy-Duty Diesel-Fueled Public and Utility Fleets is one of the California Air Resources Board’s efforts to reduce both criteria pollutant emissions and exposure to toxic air contaminants. The rule mandates Public Agency and utility vehicle owners reduce diesel PM emissions from their affected vehicles through the application of Best Available Control Technology or BACT on these vehicles by specified implementation dates. Implementation is phased-in by engine model year groups.
