In 2004 the Environmental Protection Agency (EPA) signed the final rule introducing Tier 4 emission standards. The goals of the regulation are designed to preserve and improve health, but the rules also impact businesses making, selling, servicing, and purchasing portable air compressors and a wide range of other equipment with affected diesel engines. 

The impact Tier 4 final engines have on these businesses and their operations are profound. In some cases, the new engines cause outright panic to adapt to what some users consider complex technology but these changes impact many commonly used machines. The complications are not limited to air compressors and encompass just about ever diesel engine driven product/piece of equipment in the rental store's fleet including excavators and other construction equipment, forklifts, and utility equipment such as generators, pumps, and compressors.
