Step 5b

Emission Modeling

Before a permit is issued, the department must determine if the emissions from the facility meet ambient air quality standards and all applicable emission limitations. This is done by calculating the worst case emission rates and where appropriate, using computer models to predict the concentration of air pollution around the facility. If the project cannot meet a standard or a limitation, the facility has an opportunity to propose equipment changes, emission reductions, or material substitutions that would ensure that the standards and limitations will be met. Examples include changing the height of a stack or adding air pollution control equipment.
