Q327. If multiple subparts apply to our sources such as subparts A, C, and D, are we reporting data under all three subparts?
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.

Yes, you would be required to report data for each applicable subpart at a facility. Units subject to subpart D would not need to be separately identified and reported under subpart C, but if a facility contains subpart C units and subpart D units, the units should be reported under subparts C and D in e-GGRT, respectively.
