emission factors. AP-42 is periodically updated by EPA to respond to new emission factor needs of EPA, State, and local air pollution control programs and industry. An emission factor relates the quantity (weight) of pollutants emitted to a unit of activity of the source. The uses for the emission factors reported in AP-42 include 1.
Jul 09, 2021 Air Emissions Factors and Quantification. slide 1 of 1. An emissions factor is a representative value that attempts to relate the quantity of a pollutant emitted with an industrial activity. 1. Emissions factors are tools for building emissions inventories, guiding air quality management decisions and developing emissions control strategies.

Feb 01, 2006 Total dust emissions from aggregate storage piles result from several distinct source activities within the storage cycle 1. Loading of aggregate onto storage piles (batch or continuous drop operations). 2. Equipment traffic in storage area. 3. Wind erosion of pile surfaces and ground areas around piles. 4. Loadout of aggregate for shipment or for return to the
