Cal e-GGRT Help

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?

Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.

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.
