One of the most celebrated achievements of Christie Todd Whitman as US EPA Director is the regulations of particulates from diesel fuel. As a matter of fact, yesterday, the regulation celebrated it's 13th year of environmental improvement.

The Bush administration (click here) proposed rules yesterday that would deeply cut the soot, sulfur and smog-forming pollution from diesel engines in construction, farm and other industrial equipment.
Over the next decade, the proposed rules would phase in both a cleanup of the high-sulfur diesel fuel consumed by such engines and far stricter requirements for emissions controls on the engines themselves.
Shifting to cleaner diesel for the nonroad fleet would cost about $1.5 billion a year over the next 27 years, but that would be more than offset by savings estimated at $16 billion to $80 billion a year from prolonged lives and avoided health-care costs, administration officials said.
The proposed changes were lauded by environmentalists often at odds with the Bush administration and received muted support from affected industry groups.
The rules, proposed by the Environmental Protection Agency, could be adjusted before they start taking effect next spring. But Christie Whitman, the E.P.A. administrator, said the threat to public health was clear and the costs were justified....
That was 2003 and the 'phase in' began spring of 2004. The 'phase in' was to be completed in ten years or 2013.
The reason such new regulations are phased in is because of the capital investment companies have to make in compliance of the law. Ten years.
This is Koch today.

...The planned upgrades (click here) are designed to more efficiently process hydrocarbons that have gone through initial refining steps, turning them into ultralow-sulfur motor fuels, he said. The largest investment is the replacement of two 1960s-era coking units and integrated heaters that are a key step in converting asphalt, or “bottoms,” into higher-value fuels. The refinery will remain a major asphalt producer, however.
Federal rules already require refineries to produce diesel with less sulfur, a major contributor to diesel particulate emissions. Rules for reducing sulfur in gasoline are being phased in over several years.
