4 wheels. These emission factors will be used for vehicle travel over unpaved roads for all activities in the study area. Table in Section of AP42, Western Surface Coal Mining, presents a PM10 emission factor for bulldozing of overburden of lb/ton moved. The truck loading and unloading
Available data indicate that PM10 and emissions from limestone and granite processing operations are similar. Therefore, the emission factors developed from the emissions data gathered at limestone and granite processing facilities are considered to be representative of typical crushed stone processing operations. Emission factors for ...
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 AP42 Section were retained for hand fired units.

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 of 2018, the last edition is the 5th from 2010.
Criteria for Recommendations Three criteria form the basis for recommending addition of emission factors to AP42: 1. Emission factors are available for sources for which no factors are currently reported in AP42. 2. For sources that have factors currently reported in AP42, addi tional factors of equal or higher quality rating are ...

Aug 15, 2017· This work focuses on dust emissions from mineral storage piles, which are usually modelled as source terms by means of the algorithm proposed in the AP42 US EPA standard. Unfortunately, this algorithm tends to overestimate emissions, and when coupled with a Gaussian dispersion model, it leads to inaccurate results in terms of estimation of ...

The aggregate handling process emission factors for various particle sizes depend uponthe particle size multiplier.

Recently, EPA revised AP42 Section, 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.
The data provided by the FHWA is useful in determining the new miles of roadway constructed on a yearly basis. Information Sources—Construction Emission Factors Two chapters of the EPA handbook, "Compilation of Air Emission Factors" [AP 42]l apply to particulate matter emissions from construction activities.
The document "Compilation of Air Pollutant Emission Factors" (commonly known as AP42) has been published by the Environmental Protection Agency (EPA) since February 1972, and represents a compilation of emission factors for the most significant emission source categories.
