Q86. Does Tier 3 have to be used if a unit is less than or equal to 250 mmBtu per hour, but has a continuous gas chromatograph to determine carbon content?
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.
Tier 3 is not required for any unit that is less than or equal to 250 mmBtu/hr, however a source may opt to use Tier 3 if it has the capability of determining carbon content and (if applicable) molecular weight at the required frequency specified in §98.34(b).
