The Environmental Protection Agency recently gave its nod of approval to Caterpillar's full line of off-road engines compliant with Tier 3 standards. Tier 3 regulations, which apply to clean diesel engines used in construction and mining machines and industrial power equipment, do not go into effect until January 2005.

Caterpillar was able to meet these standards earlier by using ACERT technology. For more information on Caterpillar's clean engines, visit www.cat.com.
