Ultra Low Sulfur Diesel (ULSD) Fuel Hazard
Avoid Static Electricity Risk When Refueling
WARNING - EXPLOSION HAZARD
Ultra Low Sulfur Diesel (ULSD) poses a greater
static ignition hazard than earlier diesel
formulations with higher Sulfur content. Avoid death
or serious injury from fire or explosion; consult
with your fuel or fuel system supplier to ensure
the delivery system is in compliance with
fueling standards for proper grounding and
bonding practices.
EPA Regulation Overview for
Clean Air Diesel
U.S. Environmental Protection Agency (EPA)
regulations require a major reduction in the sulfur
content of diesel fuels and emission levels from
diesel engines and vehicles. To meet the EPA
regulations, the petroleum industry is producing
Ultra Low Sulfur Diesel (ULSD) fuel, a cleaner-
burning diesel fuel containing a maximum 15 parts-
per-million (ppm) sulfur.
Since 2006, diesel fuel produced or imported is
required to be ULSD fuel. ULSD is replacing Low
Sulfur Diesel (LSD) fuel, which contains a
maximum of 500 ppm sulfur. Used in combination
with cleaner-burning diesel engines and vehicles,
ULSD fuel helps to improve air quality by
significantly reducing emissions. As of
December 1, 2010, all highway and non-highway
diesel fuel offered for sale must be ULSD fuel.
EPA Suggested Diesel Fuel Pump
Labels
Below are example EPA 40 CFR compliant labels
that should be seen on ULSD fuel pumps used for
on-highway and off-highway applications. These
types of labels help identify the different types of
fuel now available to users.
