emissions associated with each fuel using the methods specified in section 95125(g)(4).
Start-Up Fuels. The operators of generating facilities that primarily combust biomass-derived fuels but that combust fossil fuels for start-up, shut-down, or malfunction operating periods only, shall calculate and include CO2 emissions from fossil fuel combustion using the method provided in section 95125(a) or methods provided in sections 95125(c)-(e).
Calculation of N2O and CH4 from Stationary Combustion. Operators of generating facilities shall use the methodologies provided in section 95125(b) to calculate and include N2O and CH4 emissions from stationary combustion.
(e) Calculation of CO2 Process Emissions from Acid Gas Scrubbing. Operators that use acid gas scrubbers or add an acid gas reagent to the combustion source shall include CO2 emissions from these processes if these emissions are not already captured in CO2 emissions calculations based on a continuous emissions monitoring system. The operator shall calculate CO2 emissions from the acid gas processes using the following equation:
CO2 = S * R * (CO2 MW
CO2 = CO2 emitted from sorbent for the report year, metric tonnes; S = Limestone or other sorbent used in the report year, metric tonnes; R = Ratio of moles of CO2 released upon capture of one mole of acid gas;
= molecular weight of carbon dioxide (44);
Sorbent MW = molecular weight of sorbent (if calcium carbonate, 100).
Determining Fugitive SF6 Emissions. Operators of generating facilities, retail providers, and marketers shall use the methodology provided by the U.S. EPA SF6 Emission Reduction Partnership for Electric Power Systems to determine fugitive SF6 emissions as specified in Appendix A. The operator shall convert pounds of SF6 into kilograms.
Determining Fugitive HFC Emissions. Operators of generating facilities shall calculate fugitive HFC emissions separately for each HFC compound used in cooling units that support power generation or are used in heat transfers to cool stack gases using the methodology provided by U.S. EPA SF6 Emission Reduction Partnership but substituting HFCs for SF6 in the methodology. The operator shall convert pounds of HFCs into kilograms. This section does not apply to air or water cooling systems or condensers that do not contain HFCs.
(1) Operators who are reporting by individual cooling unit may elect to use service logs to document HFC usage and emissions. Service logs should
