  • The total annual CO{~}2~ 2 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 CO{~}2~ 2 emissions. This includes both CO{~}2~ 2 emissions from the combustion of biomass fuels and the biogenic portion of CO{~}2~ 2 emissions from fuels with a mixed biogenic and fossil component \ [98.36(d)(1)(ix)\]unmigrated-wiki-markup

    For each unit for which the facility selects "*CEMS*" as the Part 75 methodology used to determine CO{~}2~ 2 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 CO{~}2~ 2 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 CO{~}2~ 2 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.

    Excerpt

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