For each unit, subpart D requires the facility to provide the following aggregated fuel emissions data:

• The total annual CO₂ emissions at the monitored location in short tons (as reported in part 75) [98.36(d)(1)(ii)]
• The total annual CO₂ emissions at the monitored location in metric tons (conversion from the short ton value reported in part 75) [98.36(d)(1)(ii)]
• The total annual biogenic CO₂ emissions. This includes both CO₂ emissions from the combustion of biomass fuels and the biogenic portion of CO₂ emissions from fuels with a mixed biogenic and fossil component [98.36(d)(1)(ix)]

For each unit for which the facility selects "CEMS" as the Part 75 methodology used to determine CO₂ mass emissions, subpart D requires the facility to provide the following additional information [98.3(c)(8)]:

• The total number of operating hours during the year that CO₂ concentration was missing
• The total number of operating hours during the year that stack gas flow rate was missing
• The total number of operating hours during the year that moisture content was missing (only if a continuous moisture monitor was in use)

For each unit for which the facility selects "Appendix G, Equation G-1" as the Part 75 methodology used to determine CO₂ mass emissions, subpart D requires the facility to provide the following additional information [98.3(c)(8)]:

• The total number of operating hours during the year that fuel carbon content was missing

For each unit for which the facility selects "Appendix G, Equation G-4" as the Part 75 methodology used to determine CO₂ mass emissions, subpart D requires the facility to provide the following additional information [98.3(c)(8)]:

• The total number of operating hours during the year that fuel flow rate was missing
• The total number of operating hours during the year that high heating value was missing

For each unit for which the facility selects "LME calculation methods in §75.19(c)(4)(iii)" as the Part 75 methodology used to determine CO₂ mass emissions, no additional information is required.
