On December 11, 2008, the Air Resources Board (ARB or
Board)approved for adoption the Truck and Bus regulation to
control emissions from nearly all existing diesel powered
heavy-duty trucks and buses operating in California.  The
regulation became effective under California law on January 8,
2010. On December 17, 2010, the staff recommended amendments to
the regulation that were subsequently adopted by the Board on
September 19, 2011. The Office of Administrative Law approved the
amendments on December 14, 2011 and the regulation became
effective on the same day.

The amended Truck and Bus Regulation delays the initial
requirement to phase-in installation of PM filters by one year to
January 1, 2012 and extends the time before a vehicle equipped
with a PM filter would have to have an engine that meets 2010
model year emission standards.  The amendments also defer initial
engine replacements for older vehicles without PM filters for two
years until January 1, 2015 at the earliest.  Prior to 2020,
replacements are limited only to 20 year old or older trucks that
are not equipped with PM filters.  By January 1, 2023, most
vehicles will need to be equipped with an engine meeting 2010
model year emission standards.
