Frequent Questions

For those with graphical data on E200/E300, will EPA allow use of either the equation or graphical for both baseline and compliance?

Graphical approaches to calculating E200 and E300 for all fuels (i.e. both baseline and compliance fuels) can be used when curve-fitting or linear interpolation are not feasible. The conversion equations provided in the regulations can only be used if the only data available to a refiner is T50 and T90 measurements (i.e. no other distillation data is available).(7/1/94)
