Carriers Must Separate Diesel by Sulfur Content, EPA Says

eginning June 1, trucking companies that use in-house central refueling facilities will be required to label their diesel pumps as either ultra-low-sulfur diesel or low-sulfur diesel, said the Environmental Protection Agency.

Carriers that buy their own fuel in bulk will be required to segregate ULSD — which must contain no more than 15 parts per million of sulfur — from low-sulfur diesel, which contains anywhere from 16 ppm to 500 ppm of sulfur.

The regulation is part of EPA’s ULSD rule, due to take effect later this year. EPA will require that 80% of highway diesel fuel refined after June and sold after Oct. 15 may have no more than 15 ppm sulfur. ULSD is needed for lower-emission 2007-model truck engines to run properly.
