• An optional unit or stack description or label [optional]
• The Part 75 methodology used to determine the CO₂ mass emissions [98.36(d)(1)(v)]
  • CEMS
  • Appendix G, Equation G-1
  • Appendix G, Equation G-4
  • Low Mass Emissions (LME) (§75.19(c)(4)(iii))
• The methodology start date and end date [98.36(d)(1)(vi)-(vii)]

  • Steam Turbine
  • Stirling Engine
  • Wind Turbine
  • Other
• The type of thermal energy generation, from the following list::
  • Cogeneration Topping Cycle
  • Cogeneration Bottoming Cycle
  • Bigeneration
  • Not Applicable (unit does not generate thermal energy)
• Gross generation, in MWh
• Net generation, in MWh
• For cogeneration or bigeneration, the total gross thermal output, in mmBtu

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

• The total annual CO₂ emissions, including biomass, at the monitored location in short tons (as reported under part 75) [98.36(d)(1)(ii)]
• The total annual CO₂ emissions, for fossil fuels only, at the monitored location in metric tons (conversion from the short ton value reported under 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)]
  • Report zero for this value if the facility elects to use the option specified in 98.3(c)(12) for the 2010 reporting year (where the facility chooses not to separately report biogenic emissions from part 75 units)

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-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 "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 "LME calculation methods in 40 CFR 75 19" as the Part 75 methodology used to determine CO₂ mass emissions, provide the following additional information:

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

You should use the Validation Report to check your work. The Validation Report performs two types of checks:

• Data Completeness: Data that are required for reporting is missing or incomplete.
• Data Quality: Data are outside of the expected range of values.

You may view the Validation Report at any time.
