Q175. What biomass activities are included in Equation MM-3, and in what cases should I subtract biomass out of equation MM-8?
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.

One example of a biomass activity included in Equation MM-3 is bringing animal fat on site to be co-processed with distillates to produce renewable diesel. Equation MM-8 only applies to blended fuels, so if you co-process biomass to produce renewable diesel, you should not use Equation MM-8.
