Q308. How do you report in e-GGRT a fuel that changed calculation methodology from Tier 1 to Tier 2 for a given configuration during the middle of the year?
A308. You must add the fuel twice for the configuration. Each addition of the fuel should specify a different calculation methodology and the calculation methodology periods should be discrete. You also must identify the change in calculation methodology in the subpart A reporting module. This approach is valid when switching between Tiers 1, 2, or 3. If switching from Tiers 1, 2, or 3 to Tier 4, a new configuration would have to be added for when the methodology was switched to Tier 4.
