Don't know what you are reading but all major USA refineries are producing enormous quantities of "Non ULSD" fuel. Marine diesel, agricultural diesel, commercial power plant diesel fuel is not ULSD. The USA sells a lot of diesel - much of it to the northern neighbor. Off highway diesel is dyed.
It was only a few posts ago I posted this......

After December 1, 2014 all highway, non-road, locomotive and marine diesel fuel produced and imported will be ULSD.

After 2014, all nonroad, locomotive, and marine (NRLM) diesel fuel must be ULSD, and all NRLM engines and equipment must use this fuel
There are others if anyone wants to research.
