controlled PM-10 emission factor was developed from only Reference 10. e Emission factors were developed by using the Aggregate and Sand Transfer Emission Factors in conjunction with the ratio of aggregate and sand used in an average yard3 of concrete. The unit for these emission factors is lb of pollutant per ton of aggregate and sand.

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. Estimates of areawide emissions; 2. Estimates of emissions for a specific facility; and 3. Evaluation of emissions relative to ambient air quality.
