Emission Factors are taken from the NSPS standards and AP-42. These factors are intended to be conservative. Actual emissions may be lowered depending on the exact model year and power rating for an individual engine. Owner/operators may use a lower EF if the specific NSPS standard for their engine is lower than the EF used here. Where needed, the following conversions were used: 1 hp = 0.7457 kW, 1 lb = 453.592 g, average BSFC = 7000 Btu/hp-hr.
