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

A327. 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.
