   New Sulfur Limits for On-Road Diesel Fuels

The U.S. Environmental Protection Agency's (EPA)
ultra low sulfur diesel fuel (ULSD) regulations
require refiners to drastically reduce the sulfur 
content in on-road diesel fuel.  Under the USLD
regulations, 80% of all on-road diesel fuel 
produced by refiners must contain a sulfur content
no greater than 15 parts per million (ppm)
beginning June 1, 2006.  The remaining 20% of
on-road diesel (LSD) fuel must meet a 500-ppm
or less sulfur content.  These two on-road diesel
fuels will coexist side by side until June 1, 2010,
when all on-road diesel fuel produced by refiners
must meet the 15-ppm sulfur standard.  Jet fuel
will remain at 3,000-ppm or less and the sulfur
content of heating oil, locomotive and marine
diesel fuel is not changed under the ULSD on-road
regulations.
