In a small number of cases, facilities report emissions from stationary combustion as well as two or more other processes. For example, a refinery who also produces petrochemicals would report the total process emissions from petroleum refining, the total process emissions from petrochemical production and the total emissions from stationary combustion. EPA is unable to determine the portion of the stationary combustion emissions that should be included in each industry group's total. In these cases, EPA attributes 100% of the stationary combustion emissions to the industry type considered to be most fossil fuel intensive. The list below shows the hierarchy of industry types considered. In the case where a facility reports emissions from 2 or more of the process listed below, the emissions from stationary combustion are attributed to the highest ranking process on this list.

1 If a facility reports emissions from stationary fuel combustion and LNG storage, Fugitive emissions from local gas distribution or onshore oil and gas production, industrial wastewater treatment, industrial waste landfills, electrical transmission and distribution equipment or miscellaneous uses of carbonates then the reported emissions from stationary combustion are allocated to a sector based on the facility’s reported NAICS code.
