The goal of the emission standards for nonroad
equipment is to lower harmful exhaust emissions, such as particulate matter (PM) and nitrogen oxides (NOx), to help promote cleaner air and maintain a sustainable environment.

Diesel power touches virtually every sector of our economy and nonroad
diesel engines are essential to the industries that are the backbone of our nation --including construction, mining, farming, industrial, railroad transportation, port and marine transportation, and airport services industries.
In its most recent nonroad
diesel rulemaking, the EPA estimated that standards imposed for nonroad
land-based diesel engines typically used in construction, agricultural, industrial and mining operations will achieve particulate matter (PM) reductions in excess of 95%.
The four Clean Air Act ("CAA") rules listed, for example, preempted state regulation of air pollution (except for California) under the CANs express preemption provisions by setting federal standards for nonroad
emission controls (280) and sulfur fuel controls.

Vehicles Require Cleaner Fuel, Slashing Emissions by 90%, S.
The waiver does not apply to motorcycles, heavy-duty vehicles, or nonroad
engines such as those in lawn mowers and chainsaws.
Coolmation says when EU regulation, Tier 4/ Stage 4 nonroad
emissions limits, required reductions in engine emission levels, JCB decided to construct new test cells to ensure its engines met the new requirements.
Indications are that most will add SCR to the mix for-Tier 4 final in 2014, though there are already some companies, mainly MTU and AGCO Sisu Power, that have adopted SCR for nonroad
applications at interim.
