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)

The original was posted in the Q&A posted on 7/1/94 which can found at http://www.epa.gov/otaq/rfg_qa.htm" See Question ID 3857 for RFG (Taken from the first question on http://www.epa.gov/otaq/regs/fuels/rfg/qa/420r03009.pdf)
For those with graphical data on E200/E300, will EPA allow use of either the equation or graphical for both baseline and compliance?
