Air Dispersion Modeling

Services Provided

  • Assisted with the monitoring of process emissions and developed appropriate emission factors.
  • Utilized dispersion modeling software to determine off-site impacts from process and combustion operations, and to demonstrate compliance with state and national ambient air quality standards.

Dispersion modeling software required input of stationary sources, receptors, planning distances, emission rates and concentrations of chemicals of concern.

Process emission sampling was performed to gather information about input parameters necessary to run the model. Using the site-specific sample results, appropriate emission factors were developed for the operations. The dispersion model was executed and the resulting impacts at placed receptors was determined.
