Q75. For a unit that combusts fossil and biomass fuels that has a CEMS for CO2 and uses Tier 4, must CO2 be reported by fuel type?
Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.
The combined CO2 from all fossil fuels must be reported separately from the combined CO2 from all biomass fuels; however, reporting CO2 by specific type of fuel (e.g., coal, oil, gas, etc.) is not required. (See 98.36(b)(7)(ii))
