Emissions Factors Emissions Factors & Policy Applications Center Emissions Factors & AP 42 Emissions Factors & AP 42, Compilation of Air Pollutant Emission Factors An emissions factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that

The AP 42 Compilation of Air Pollutant Emission Factors is a compilation of the US Environmental Protection Agency (EPA)'s emission factor information on air pollution, first published in 1968.As of 2018, the last edition is the 5th from 2010.

An alternative, consisting of the exist- ing AP-42 emission factor equation with adjustments to the original coefficient to approximate IP and PM-10 emission factors, does not acceptably predict the new emission factor data base.

(PM) emissions (not PM 10) for individual emission source at aggregate (sand and gravel), brick and tile, hot mix asphalt, cement, concrete batch plants. These factors are also applicable to emission sources other than processes identified in recently adopted Rules 1156 and 1157. The factors and equations are extracted from the US EPA AP-42 ...

Recently, EPA revised AP-42 Section 13.2.2, which contains emission factor information related to the unpaved road source category. Significantly, the recent revisions to that section changed the equation for estimating particulate matter emissions for unpaved roads creating a variable between filterable particulate matter and PM10 emissions.

Air Emission Factors for Metals Finishing Operations Glenn A. Zinkus, Zinkus Consulting Group and Kevin Klink, CH2M HILL It is widely known that limited air emission factor data related to electroplating and metals finishing operations are available. In recent years, EPA has published AP-42 emission factors related to certain

4 wheels. These emission factors will be used for vehicle travel over unpaved roads for all activities in the study area. Table 11.9-2 in Section 11.9 of AP-42, Western Surface Coal Mining, presents a PM10 emission factor for bulldozing of overburden of 0.75 lb/ton moved. The truck loading and unloading

Data from a total of six boilers were used to calculate the new emission factors. The six boilers ranged in capacity from 11,250 to 11,700 kg steam/hour (25,000 to 26,000 Ibs steam/hr). Filterable PM emission factors from the 1988 version of AP-42 Section 1.2 were retained for hand fired units.
