The Low Sulfur Era Begins

Posted on June 1, 2006

Starting June 1 the U.S. Environmental Protection Agency (EPA) requires refiners and fuel importers to cut the sulfur content of on-highway diesel fuel 97 percent, from 500 ppm to 15 ppm. The rules are issued in line with the Bush Administration's promotion of renewable energy sources and cleaner fuels, such as Ultra Low Sulfur Diesel (ULSD), the agency said.

ULSD enables advanced pollution control technology for cars, trucks and buses. Consumers will be able to purchase ULSD and vehicles with clean diesel technology later this year. The agency said it expects a smooth transition and will closely monitor the industry as it transitions to ULSD.

In keeping with its efforts to ensure smooth implementation, EPA is a member of the Clean Diesel Fuel Alliance, a stakeholder group dedicated to providing the public ULSD-related information. More information is at: http://www.clean-diesel.org
