| Excerpt |

For each unit, subpart D requires the facility to provide the following aggregated fuel emissions data: | Wiki Markup |
|---|
The total annual CO{~}2~ emissions, including biomass, at the monitored location in short tons (as reported under part 75) \[98.36(d)(1)(ii)\] |
| Wiki Markup |
|---|
The total annual CO{~}2~ emissions, for fossil fuels only, at the monitored location in metric tons (conversion from the short ton value reported under part 75) \[98.36(d)(1)(ii)\] |
| Wiki Markup |
|---|
The total annual biogenic CO{~}2~ emissions. This includes both CO{~}2~ emissions from the combustion of biomass fuels and the biogenic portion of CO{~}2~ 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)
| Wiki Markup |
|---|
For each unit for which the facility selects "*CEMS*" as the Part 75 methodology used to determine CO{~}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)
| Wiki Markup |
|---|
For each unit for which the facility selects "*Appendix G, Equation G-4*" as the Part 75 methodology used to determine CO{~}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
| Wiki Markup |
|---|
For each unit for which the facility selects "*Appendix G, Equation G-1*" as the Part 75 methodology used to determine CO{~}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 "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
