of Air Pollution From Nonroad Diesel Engines and Fuel (278 pages, in English)
6. Description of content:   The Agency is proposing new emission standards for nonroad
diesel engines and sulfur reductions in nonroad diesel fuel that will dramatically reduce
emissions attributed to nonroad diesel engines.  This comprehensive national program will
regulate nonroad diesel engines and diesel fuel as a system.  New engine standards will
begin to take effect in the 2008 model year.  These standards are based on the use ofadvanced exhaust emission control devices.  Nonroad diesel fuel sulfur reductions of up
to 99% from existing levels will provide signific ant health benefits as well as facilitate the
introduction of high-efficiency catalytic exhaust emission control devices as these devices
are damaged by sulfur.  These fuel controls would begin in mid 2007.  Today’s nonroad
proposal is largely based on the Agency’s 2007 highway diesel program.

To benefit public health and welfare and the environment.
