In this report, emissions were estimated for vessels propelled by Category 3 engines (those with cylinder displacements above 30 liters). Chapter 1 reviews the emissions data available for these types of engines and provides estimates of average emission factors to be used in later emission estimates. Chapter 2 details which ports were considered similar and matched to each of several ports for which detailed port call data was available from earlier EPA work in order to estimate emissions for all ports. Chapter 3 provides a description of how the emission estimates near and at US ports were performed and summarizes results for all ports combined. Chapter 4 describes and summarizes emissions estimates for these type of vessels operating in US waters outside the area covered by the Chapter 3 estimates. Chapter 5 estimates future year emissions at US ports. Chapter 6 provides a sensitivity analysis for a number of assumptions and estimates used in the compilation of the Chapter 3 results. / Supplementary Notes: Prepared in cooperation with Pechan (E.H.) and Associates, Inc., Springfield, VA.
