Our meteorologists use sophisticated dispersion modeling techniques to show accurate predictions of ambient concentrations to meet air quality standards. Our CCMs are experts in complex air dispersion modeling. They use modeling systems such as CALPUFF, AERMOD and CAL3QHC, and three-dimensional meteorological modeling with CALMET. They not only apply the models, but also have experience in model development, model evaluation, and training.
Modeling scenarios include stack emissions, accidental releases, fugitive emission sources, and mobile sources. We also model atypical release scenarios, such as cooling tower modeling with SACTI. By performing these complex air pollution control assessments we are able to guide our oil-, natural gas-, and coal-fired energy projects and industrial clients through how best to meet regulatory requirements.
We are skilled at applying the results of modeling analyses to inform human health risk and environmental justice-related concerns. In support of these analyses, Epsilon’s trusted senior staff have provided expert testimony to state oversight boards, local planning boards, and at public hearings.
