This informational document provides basic and current descriptions of gasoline marketing operations and methods that are available to control hydrocarbon emissions from these operations. The three types of facilities that are described are terminals, bulk plants, and service stations. Operational and business trends are also discussed. Emissions from typical facilities, including transport trucks, are estimated. The operations which lead to emissions from these facilities include (1) gasoline storage, (2) gasoline loading at terminal and bulk plants, (3) gasoline delivery to bulk plants and service stations, and (4) the refueling of vehicles at service stations. Available and possible methods for controlling emissions are described with their estimated control efficiencies and costs. The costs for control of a unit weight of hydrocarbon are calculated from these estimates. This report also includes a bibliograpy of references cited in the text, and supplementary sources of information.
