Q69. Does fuel use for comfort heating and hot water heaters need to be reported?
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.

Per 40 CFR 98.30, stationary fuel combustion units are devices that combust solid, liquid, or gaseous fuel, generally for the purposes of producing electricity, generating steam, or providing useful heat or energy for industrial, commercial, or institutional use. Building facility heaters, including comfort heating and water heaters that combust solid, liquid, or gaseous fuel meet this definition of a stationary fuel combustion source. Therefore, they must be included in determining rule applicability and included in annual reports if they are located at an industrial, commercial, or institutional facility that is subject to the rule. A comfort heater or hot water heater that is located at a residence would not meet the source category definition in 40 CFR 98.30 and would not need to be reported.
