Locomotive, marine and non-road diesel fuel standards begin at later dates (except in California).

EPA fuel standards for locomotive, marine and non-road diesel fuel engines and equipment,
such as farm or construction equipment, become effective at dates later than those for
highway vehicles:

Except in California, compliance dates for Non-Road, Locomotive and Marine fuels in the years indicated are: June 1 for refiners and importers, August 1 downstream from refineries through fuel terminals, October 1 for retail outlets, and December 1 for in-use.
In California, all diesel fuel transitioned to ULSD in 2006. Locomotive and Marine diesel fuels were required to transition to 15 ppm ULSD effective January 1, 2007.
