Development of an improved inventory of emissions from pleasure craft in California. Final report

Technical Report ·
OSTI ID:166985
An updated emissions inventory for California pleasure craft covers total organic gases (TOG), Nox, CO, SOx, and particulate matter (PM). A survey of over 10,000 pleasure craft owners from June 1993 to May 1994 ascertained spatial and temporal utilization of pleasure craft and collected updated consumption rates. Annual fuel consumption is estimated for vessels by propulsion/engine combinations by region (Northern, Central, and Southern). From these, regional and county-level emissions are estimated using a model (PCEM) that includes emission estimates from DMV-registered vessels, Coast Guard-documented vessels, and rental vessels. Fuel consumption is multiplied by emission factors for each propulsion/engine type and allocated to counties with spatial allocation factors developed from the survey data. Temporal activity profiles are derived from the survey data.
