Emission Estimation Calculators - Booklet 1

Fugitive Dust Emissions from Abrasive Blasting

Abrasive blasting involves blasting particles of sand or other material to clean or texturize a surface. The substances of concern in this activity are Criteria Air Contaminants (Part 4 Substances). Depending on the composition of the abrasive material and the material being abraded, other contaminants may also be released (ex. metals).

Suggested estimation methodology: Emission Factor

Input Data

The emission factors for estimating total particulate matter emissions from abrasive blasting operation are available at three different wind speeds. Determine the annual mean wind speed for your area. Annual mean wind speed data is available at the Climate Data web site. The emission factors for PM10 (Particulate matter with a diameter less than or equal to 10 micrometres) and PM2.5 (Particulate matter with a diameter less than or equal to 2.5 micrometres.) do not vary with wind speed.

Use the emission factors to determine the annual emissions of each substance using the general equation for emissions estimation:

E = A x EF

where:

  • E = annual emissions
  • A = activity rate
  • EF = emission factor

Note on Emissions Factors

National Pollutant Release Inventory (NPRI) Basis of Estimate Code = E2 (Published Emission Factors).

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column. If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

The emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)
