Particulate Matter Emission Factor Updates from U.S. EPA for Natural Gas, Process Gas and LPG
Particulate matter emission factors for natural gas, process gas and LPG have been revised by Roy Huntley of the EPA. The reason for this adjustment is that the EPA believes that the current AP-42 factors for condensable PM emissions are too high.
The electronic emission inventory reporting website (e-Services) will perform calculations using the revised EPA emission factors from Roy Huntley as the default emission factors. The unrevised emission factors will still be available in AP-42/WebFIRE. Please select the link below based on your facility’s air permit type to reference the updated emission factors.
An explanation of this issue can be found on the EPA’s National Emission Inventory (NEI) website.
- Option C and Option D registration permittees revised natural gas, process gas and LPG emission factors
- Large Inventory Type Permit holders revised natural gas, process gas and LPG emission factors
