One of the best diesel articles I have seen I a while.  Especially points
out the emissions changes that must be in place by 2007.
Reduced sulfur and low sulfur fuels are already in the system in many parts
of the US and Canada.
BP and some other major fuels providers have clearly stated that the only
way to make some plants meet fuels requirements and to meet the demand is to
blend B20 with their normal reduced sulfur fuel output

It also mentions the 50 state issue.  Several northeast states formed a
coalition and created rules when nothing was in place and exempted US
vehicles by defining an exemption for passenger vehicles with commercial and
truck based SUV.  This created a regular US/Canada class, a California
class(based on solid science), and a Northeast politics as usual class.
However note that these laws are all about to become "leveled" because they
based them on what at the time were the proposed 2007 and 20010 emissions
standards. The phase in only permits federal exemptions.
