The 1988 AP-42 Section 1.11 used these results to determine emission factors for particulate matter, particulate matter less than ten microns in diameter (PM-10), lead, carbon monoxide, and HC1. The same results are incorporated into the emission factor determinations for the updated AP-42 section.
The U.S. Environmental Protection Agency (EPA) has developed and published emission factors for various industries and sources. These emission factors are documented in the EPA publication Compilation of Air Pollutant Emission Factors (AP-42) 1 and also in the EPA Clearinghouse for Inventories and Emission Factors (CHIEF) 2.
Search and Retrieval of EPA Emissions Factors; Search and Retrieval of EPA Emissions Factors. WebFIRE contains the EPA’s emissions factors for criteria and hazardous air pollutants (HAP) for industrial and non-industrial processes. To retrieve EPA emissions factors, you can use either a Simple or Detailed Search.
In general, the use of country-specific emission factors would provide more accurate estimates of emissions than the use of the default emission factors. According to the IPCC, if an activity is a major source of emissions for a country ('key source'), it is 'good practice' to develop a country-specific emission factor for that activity.
Due to the large variation in emissions from internal combustion engine and changing emissions standards, AP-42 emission factors may not be the best choice if a stack test will be required. Potential Issues When Calculating Air Emissions. Using the wrong emission factor based on the process or emission source type.
Emission factor ratings in AP-42 (discussed below) provide indications of the robustness, or appropriateness, of emission factors for estimating average emissions for a source activity. Usually, data are insufficient to indicate the influence of various process parameters such as temperature and reactant concentrations.
Emission factors / AP 42 (Compilation of air pollutant emission factors) This EPA document includes factors from a wide variety of industries and processes. Some factors are useful for estimating emissions associated with polyurethane manufacturing processes e.g. solvents or other volatile organic compounds (VOCs).

Sep 07, 2012· The listed emission factors have a rating, A through D, which indicates the effective confidence in the factor (A indicates the highest confidence). If you think your facility’s emissions deviate slightly from the emission factors in AP-42, you’d have a better chance of making a convincing argument over a factor rated D than one rated A.
