1. Ultra Low Sulfur Diesel (ULSD)
Labeling Requirements
and
Implementation Dates

2. Ultra Low Sulfur Diesel (ULSD) - What is it?
A rule promulgated by the Federal EPA mandates the use of ULSD in diesel powered vehicles
The rule affects the entire United States
What is ULSD?
Diesel fuel that contains no more than 15 ppm sulfur
Current on-road diesel fuel may contain no more than 500 ppm sulfur
Current off-road diesel fuel can contain greater than 500 ppm sulfur

3. Ultra Low Sulfur Diesel (ULSD) - What is it?
ULSD can be used in any diesel engine – the grade is still #1 or #2
2007 model year and newer vehicles must use ULSD
End users who intentionally misfuel are subject to civil penalties
Care must be taken not to cross contaminate 15 ppm ULSD with 500 ppm sulfur diesel during handling and transportation -
This includes pump calibration testing and return of product to storage tanks by weights and measures officials and service agents

4. Ultra Low Sulfur Diesel (ULSD) – in California
The California Air Resources Board is making no distinction in their switch to ULSD - it will be required for both on-road and off-road vehicles and equipment with no exceptions. All diesel will be required to meet the 15 ppm sulfur content.
The rule becomes effective June 1, 2006 – 100% of diesel produced must be 15 ppm ULSD
July 15, 2006 – terminals must distribute 15 ppm ULSD
September 1, 2006 – retailers must sell 15 ppm ULSD
Intra-state locomotives and marine harbor craft must use ULSD by January 1, 2007

5. Ultra Low Sulfur Diesel (ULSD) – Labeling Requirements
The Federal EPA has amended their regulations to define “California diesel fuel” as any diesel fuel physically within California and sold as a engine fuel in California that meets the requirements of CCR Title 13 after May 31, 2006.
California labeling requirements will remain as they are:
Brand name, Grade (#1 or 2) and Product (Diesel Fuel)
The following implementation dates and labeling requirements will not apply in California.

6. Ultra Low Sulfur Diesel (ULSD) - What is it?
The rule becomes effective June 1, 2006 –
80% of on-road diesel produced must be 15 ppm ULSD
20% of on-road diesel produced can be 500 ppm sulfur diesel**
October 15, 2006 – retail dispensers must reflect which fuel is being sold **
May sell either 15 ppm or 500 ppm diesel fuel or may sell both at retail as long as each dispenser is labeled properly **
After October 1, 2010 all on-road diesel fuel must be 15 ppm ULSD **
Off-road diesel fuel must be 500 ppm diesel by 2010 – most will be ULSD by then **
** Except in California

7. Ultra Low Sulfur Diesel (ULSD) – Labeling Requirements
Highway (On-Road) Fuel Pump Labels
For pumps dispensing 15-ppm ULSD highway diesel, the following label is required from June 1, May 31, 2010:
ULTRA LOW SULFUR DIESEL FUEL (15-ppm Sulfur Maximum)
Required for use in all model year 2007 and later highway diesel vehicles
and engines. Recommended for use in all diesel vehicles and engines.

8. Ultra Low Sulfur Diesel (ULSD) – Labeling Requirements
Highway (On-Road) Fuel Pump Labels
For pumps dispensing 500 ppm diesel fuel, the following label is required from June 1, 2006 – September 30, 2010:
The label may not be posted after September 30, 2010
LOW SULFUR HIGHWAY DIESEL FUEL (500-ppm Sulfur Maximum)
WARNING
Federal law prohibits use in all model year 2007 and later vehicles and
engines. Its use may damage these vehicles and engines.

9. Ultra Low Sulfur Diesel (ULSD) – Labeling Requirements
Off-Road Pump Labels
For pumps dispensing off-road diesel fuel that does not meet motor vehicle fuel standards, the following label is required from June 1, 2006 – May 31, 2007:
NON-HIGHWAY DIESEL FUEL (May exceed 500-ppm Sulfur)
WARNING
Federal Law prohibits use in any highway vehicle or
engine. Its use may damage these vehicles and engines.

10. Ultra Low Sulfur Diesel (ULSD) – Labeling Requirements
The EPA label must be conspicuously posted in the upper two-thirds of the front panel on each customer side of the dispenser
Required to be legible block letters, not less than 24 point bold type, in a color that contrasts with the background
Enforcement of the required labeling is the responsibility of the Federal EPA
