The general equation for estimation using an emission factor: E = A x EF where: E = emissions A = activity rate EF = emission factor Input data and substance releases The emission factors for estimating particulate emissions from a drop operation can be calculated as a function of the particle size, mean wind speed, and material moisture …

Each of these mining operations has specific emissions factors accounting for the different means by which the resources are extracted. In 2014, mining and quarrying in the US, Puerto Rico, and US Islands resulted in approximately 585,991 tons of PM10-PRI emissions. For this source category the following SCC is assigned: SCC SCC Level 1

The sulfur dioxide emission factor was shown as 0.087 lb/ton of total feed charged. The conversion was incorrect. The factor was corrected to 0.87 lb/ton. …

Total dust emissions from aggregate storage piles result from several distinct source activities within the storage cycle: 1. Loading of aggregate onto storage piles …

AP-42, Compilation of Air Pollutant Emission Factors, has been published since 1972 as the primary compilation of EPA's emission factor information. It contains emission factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.

2. Secondary Crushing uses Tertiary Crushing emission factors per footnote (n) of AP-42 Ch. 11.19.2-2. from AP-42 Ch. 13.2.4 was used to estimate PM2.5 emission factors. PM2.5 EF = (PM10 EF/0.35)*0.053 Truck Unloading Fragmented Stone Truck Loading Conveyor, Crushed Stone Emission Factor Source Total PM emissions (ton/yr) Total …

English units). Although no emission factors are presented for construction sand and gravel processing, emission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section 11.19.2, "Crushed Stone Processing." In the absence of other data, the emission factors presented in ...

Emission Factors, Volume 1, Fifth Edition, AP-42 in October 1997 that presents estimates of ... Western Surface Coal Mining, presents a PM10 emission factor for bulldozing of overburden of 0.75 lb/ton moved. The truck loading and unloading emission factor comes from Section 13.2.4, Aggregate Handling and Storage Piles. The equation

EPA has drafted new/revised emission factors for AP-42 Chapter 2, Section 2 – Sewage Sludge Incineration. These factors can be found on the Draft Revisions to AP-42 Chapter 2, Section 2 – Sewage Sludge Incineration page. The comment period for these factors ends on March 10, 2023. To submit comments, please email …

The emissions factors have been developed and compiled from source test data, material balance studies, and engineering estimates. The Fifth Edition of AP-42 was published in January 1995. Since then EPA has published supplements and updates to the fifteen chapters available in Volume I, Stationary Point and Area Sources.
