Rule eases diesel fuel transition
To facilitate the transition to
the ultra-low sulfur diesel (ULSD) fuel, EPA will issue a rule
later this year that will take two actions. The first action will
shift the retail compliance date from September 1 to October 15,
2006, to allow more time for terminals and retail outlets to comply.
During this extended transition
period, diesel fuel meeting a 22 ppm level can be marketed as
ULSD downstream in order to speed the transition. This action
will help ensure nationwide transition to 15 ppm ULSD prior to
the introduction of new clean diesel trucks and buses.
The second action will establish
a test program, in cooperation with the fuel industry, to collect
the data necessary to determine if the current 2 ppm testing tolerance
is sufficient. These transitional items will not interfere with
the planned introduction of clean diesel vehicles and engines
anticipated in the autumn of 2006, nor will they reduce the environmental
benefits that will be achieved by this historic Clean Diesel Program.
