arbcombo -- Truck and Bus Regulation Early Access to Certain Approved Amendments

Posted: 27 Jun 2014 16:59:53
The Air Resources Board (ARB or Board) approved amendments to the
Truck and Bus Regulation at its April 24-25, 2014 meeting.   The
approved amendments are intended to better ensure that the air
quality benefits originally envisioned by the regulation will be
achieved, while concurrently providing additional flexibility to
vehicle owners.

An advisory has been made available to explain how truck and bus
owners can plan for and take advantage of recently approved
amendments to the Truck and Bus regulation.  The advisory also
describes the steps owners that previously claimed good faith
efforts must now take to comply.

The regulation requires diesel truck and bus owners to take steps
to reduce their engine emissions.  The regulation is a part of
the State's plan to meet federal ambient air quality standards
and to protect public health, particularly near roadways and
distribution centers where exposures frequently reach unhealthy
levels.  Nearly all trucks and buses with a manufacturer's gross
vehicle weight rating greater than 14,000 pounds that operate in
California are required to be upgraded between 2012 and 2023 to
reduce exhaust emissions.  

Most heavier trucks and buses (with a gross vehicle weight rating
greater than 26,000 pounds) will be required to have a PM filter
by January 1, 2014.  There are certain exceptions to these
requirements for owners that have reported to use flexibility
options allowed under the regulation.  These include, but are not
limited to, certain agricultural and limited-use work trucks,
low-use vehicles, and vehicles operated in certain rural areas.
