Nonroad Vehicles and Equipment

Reducing Nonroad Diesel Emissions EPA is proposing new emission standards for nonroad diesel engines used in construction, agricultural and industrial operations. The Agency is also proposing a more than 99-percent reduction in the sulfur content in fuel used by these engines. The proposed emission standards would achieve a reduction in particulate matter (PM) and nitrogen oxide (NOx) levels of more than 90 percent. This will significantly improve the air quality for Americans nationwide.
