Air Quality Data and Dispersion Modeling

What is Air Dispersion Modeling?

An air dispersion model is a set of mathematical equations that relates the release of air pollutants from emission sources to the corresponding concentration of pollutants in the ambient air. These models are tools used to determine if the emissions from a source can meet a specific ambient standard.

Who needs to do this?

The emission sources/facilities can use air dispersion modeling to show compliance with federal and/or state air pollution control laws and regulations, such as:

Other approaches may be allowed in these regulations, but air dispersion modeling is typically the least expensive and least time consuming of these approaches.

Additional Information can be found in the Air Quality Modeling Guidelines.
