An investigation of the economic impact of various gasoline removal schedules is reported. These schedules varied in rapidity of lead removal and in the number of gasoline grades produced. Eleven proposal schedules were grouped into two classes, one related to a two-pump market system, the other to a three-pump system. In all cases one grade of gasoline was required to be lead free by 1974 to satisfy the needs of any 1975 model cars equipped with exhaust reactors requiring unleaded fuel. The basic research octane level of this gasoline was set at 93 RON. A feasibility analysis, which was required for all eleven schedules, examined approximate capital costs, pool octane numbers, aronmatics concentrations, prime blending component requirements, and year-to-year rates of increase in gasoline volume times octane. A preliminary selection was made of the slowest and fastest lead removal schedules for 3-grade cases and for 2-grade cases. Spot year detailed analysis of all schedules was also determined. The report includes a detailed summary of conclusions, and a detailed description of the methodology used. (Author)
