The Air Resources Board has a regulation to reduce emissions from existing
off-road diesel vehicles used in California in construction, mining, and
other industries. The In-Use Off-Road Diesel Vehicle Regulation
(Off-Road Regulation) requires fleet owners to report to ARB and label
their off-road vehicles now, and then requires fleets to reduce the emissions
from their older equipment beginning in 2014. Recently, ARB adopted amendments
to the Off-Road Regulation that changed the compliance dates, administrative
requirements, and also brought both engines on privately-owned, two-engine
vehicles with certified auxiliary engines greater than 50 bhp into the Off-Road
Regulation, except for street sweepers. Owners of off-road vehicles and/or
two-engine vehicles (mentioned above) are strongly encouraged to attend this training.
Course #504 will provide an overview of the amended Off-Road Regulation,
including the applicability of the regulation, requirements currently in effect,
future compliance requirements, and will also include an overview of the Diesel
Off-Road Online Reporting System (DOORS). ARB staff will also be available
after the training to answer individual questions. For more information
regarding the Off-Road Regulation please go
