Table 4-16 shows the VOC emissions from oil production on g/gal basis. The refining and production values in Table 4-16 are shown on a total refinery emissions per gallon of gasoline basis. These emissions must be allocated to gasoline (46 percent for production and 55 percent for refining as shown in Table 4-16).

Energy inputs for producing reformulated diesel were estimated from an EMA study on low sulfur diesel formulations. LP model runs, performed by MathPro, estimated the energy inputs for an oil refinery shown in Table 4-17. Only the energy inputs that changed with fuel formulations are shown. Diesel production was 35 kbbl/day for all of the model runs. 80 kbbl/day of gasoline as well as other products are also produced by the refinery. The energy inputs represent a relatively small fraction of the energy in the product diesel. Taking the difference between the 20 and 150 ppm sulfur case, energy inputs to the refinery are -0.2 kbbl/day of crude oil and fuel and 18 MWh of electric power. The net difference in energy input is 4000 Btu/gal of diesel or about 3 percent
