Air Dispersion Modeling

Geosyntec skillfully guides clients through the development of strategic approaches to air permitting that often result in the avoidance of major source permitting requirements, such as Prevention of Significant Deterioration (PSD) or non-attainment area New Source Review.

However, when avoidance is not an option, our team of air dispersion modelers and control technology experts have the experience necessary to respond to the challenges associated with major source permitting requirements, including performing control technology evaluations (Best Available Control Technology and Lowest Achievable Emission Rate) and ambient air impact analyses (National Ambient Air Quality Standards, PSD Increment, and state Toxic Air Pollutant demonstrations).

Our advanced collection and measurement methods allow us to generate robust data for air dispersion models that describe the complex behavior of pollutants in the air and how they interact with their environment. By replicating such conditions as wind speed, wind direction, atmospheric chemistry, temperatures, and mixing height, our models can estimate the concentration of a wide array of emissions as they move through or away from their source.

Armed with this data, our engineers and scientists can accurately assess how a source affects a particular area and consult with clients on the development of comprehensive environmental management strategies that allow industrial facilities to meet local, state, and national compliance requirements.
