SPADDs have moved to ULSD at different rates.  The figure on the left shows PADDs 2 and 3 still were producing a fairly sizable volume of 500 ppm diesel.  The figure on the right shows the shares of distillate being produced in each PADD.
	SIn PADDs 2 and 3, ULSD projects are in the works that should be completed in 2007.
	SPADD 4 was an area of concern before the program began because of its isolation and the ability of some PADD 4 refineries to take advantage of the small-refinery delays that were allowed.  But PADD 4 refineries converted almost entirely to ULSD.
