Abstract	The oxides of nitrogen (NOx) emission levels from heavy duty engines used in vehicles over 8,500 lbs gross vehicle weight (GVW) will drop from the current level of 5 grams per brake horsepower-hour (g/bhp-hr) to 4.0 g/bhp-hr in 1998. The SOP proposes that engine manufacturers meet a combined standard of 2.4 g.bhp-hr for nonmethane hydrocarbon (NMHC) and NOx emissions by 2004. The methods that might be used to reach the SOP goals are the content of this report. Descriptions of the technologies and costs of technologies to meet the proposed 2.4 g/bhp-hr NOx plus NMHC standards were obtained through candid conversations with heavy-duty engine manufacturers, equipment manufacturers, manufacturer associations, research organizations, and various publications. This information was used to present a coherent set of likely technologies for meeting the future standards. When information was not provided or only partially provided, engineering and economic judgement was used to provide additional details.
