Proposed Rule for Control of Air Pollution From New Motor Vehicles: Proposed Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements
On this page:
Rule Summary
The U.S. Environmental Protection Agency (EPA) is proposing a major program to significantly reduce emissions from heavy-duty engines and vehicles. This comprehensive national control program regulates the heavy-duty vehicle and its fuel as a single system. We are proposing new emission standards that will begin to take effect in 2007 and corresponding diesel fuel requirements that take effect in 2006. If fully implemented as proposed, this program will reduce emissions of oxides of nitrogen (NOx) and nonmethane hydrocarbons (NMHC), key ingredients in ozone, by 2.8 million and 305,000 tons per year in 2030, respectively. Particulate emissions from these vehicles would be reduced by 110,000 tons per year in 2030.
