The ASG modelling team has a wealth of experience in generating Emission Inventories that can assist in providing the answers to complex air pollution problems.

Use of applicable emission factors and rates is critical for developing permitting strategies, determining applicable regulations, and performing air dispersion modelling analyses. We are practiced at using EPA and EU emissions factors for projects when necessary.

Air quality permitting requires a comprehensive facility/plant inventory development of all potential, design and actual air emissions sources.

ASG can:

  • Support in the development of a precise inventory of emissions that is necessary for correct annual permit fees to regulatory agencies, supporting companies’ key performance indices such as tracking air shed contributions and, understanding the magnitude of emission contribution from sources.
  • Build client specific custom built GUI interfaces. An example is a mine facility where dust emissions need to be kept below a certain level. By managing the various sources at the mine site through real time and forecast modelling and monitoring, the mine manager can control and better manage those sources on a day-to-day basis.

Emission inventories are often highly complex. Most facilities have emission sources that are difficult to classify and quantify, such as raw material storage piles, material handling operations, solvent cleaning of parts and machinery, surface coating operations, and dust from roadways and parking lots.

ASG staff have:

  • Performed complex calculations in generating Emission Inventories for numerous facilities internationally.
  • Dealt with many discrete emissions from point sources, area sources, line sources and mobile sources (transportations cars, truck, rail and aviation) as well as non-discrete emissions such as fugitive emissions from various operations.
  • Worked on various sources such as oil well-head emissions operations, tank truck loading operations, fume hood emissions, aluminium plants, cement factories, oil and gas pipeline leakages, and fugitive emissions.

We will engage our experience and resources to ensure that appropriate emission factors for each source and multiple species are correctly addressed.
