Q333. Can you change configuration types from year to year?

A337.  No, you are only required to identify fuel types for which you calculated emissions according to Part 98. However, if a fuel was carried over from a prior year by e-GGRT and you expect to use the fuel again in future years, you can keep it in e-GGRT and report zero emissions so that it will continue to be carried forward by eGGRT.
