26.1 Sector Descriptions and Overview
Industrial, Commercial, and Institutional (ICI) fuel combustion sources are a significant portion of the total emissions inventory for many areas and include emissions from boilers, engines, and other combustion sources from the industrial, commercial, and institutional sectors that are not reported as point sources. This source category includes emissions from combustion of coal, distillate fuel oil, residual fuel oil, kerosene, liquefied petroleum gas (LPG), natural gas, and wood. Unless all ICI combustion emission sources are provided in an S/L/T point inventory submittal, it is necessary for inventory preparers to estimate ICI combustion nonpoint source emissions.
The EIS sectors documented in this section include these nonpoint emissions from ICI fuel combustion:
• Fuel Comb - Industrial Boilers, ICEs - Biomass
• Fuel Comb - Industrial Boilers, ICEs - Coal
• Fuel Comb - Industrial Boilers, ICEs - Natural Gas
• Fuel Comb - Industrial Boilers, ICEs - Oil
• Fuel Comb - Industrial Boilers, ICEs - Other
• Fuel Comb - Comm/Institutional - Biomass
• Fuel Comb - Comm/Institutional - Coal
• Fuel Comb - Comm/Institutional - Natural Gas
• Fuel Comb - Comm/Institutional - Oil
• Fuel Comb - Comm/Institutional - Other
We document all these sectors in this section because EPA generates all the nonpoint emissions from these EIS sectors via the “ICI Tool” module. S/L/Ts were encouraged to submit Point inventory activity data -via many options reflecting sector and fuel type- in order to compute the “remaining” nonpoint emissions component to these sectors.
Table 26.1 shows, for ICI fuel combustion, the nonpoint SCCs covered by the EPA ICI Tool as well emissions directly submitted by State/Local and Tribal agencies for the 2020 NEI. The SCC level 2, 3 and 4 descriptions are also provided except for the last SCC (2801520000), where the full SCC description is provided. The SCC level 1 description is “Stationary Source Fuel Combustion” for all SCCs except the last one. The leading sector description is “Fuel Comb” for all SCCs.
