Abstract:The Environmental Protection Agency (EPA
or the Agency) established in 2000 new far
reaching emission standards beginning in 2007 for
heavy-duty diesel vehicl
es and the fuel used
in them. These standards were premised on
the introduction of new
catalyst based emission
controls for diesel engines and the removal of
a catalyst poison, sulfur, from diesel fuel. The
scale of the changes and the long-term benefit for
society have only one para
llel in the thirty plus
year history of mobile source emission cont
rol: the introduction of unleaded gasoline and
catalysts on cars in the 1970s. The monetized bene
fits of this program exceed its cost by more
than 16 to one.
Given the scope of these new
regulations and their importan
ce for public health, it is only
prudent that the Agency carefully follow the prog
ress of industry in impleme
nting this rule. This
report is the second in a series of technical pr
ogress reviews by EPA to document the status of
engine and vehicle technology development to
meet the 2007 standards. The first report,
published in June of 2002, conclude
d that progress to that time ha
d been substantial and was in
keeping with the expected progress necessary fo
r successful implementati
on of the new standards
in 2007. We concluded this based
primarily on the extensive resear
ch efforts since the rule was
finalized and the good results from that research.
This second report also considers the continui
ng progress in the research laboratory but,
more importantly, the transition of these technol
ogies from research into business plans, product
development programs, engines and
vehicles for field testing, and
finally into real products for
sale in the marketplace in 2007. Thus, while we
continue to be impressed by the amount of
technical progress shown in the laboratory, it is
the concrete steps that
manufacturers have taken
in their new product developm
ent programs that gives us great confidence for 2007.
