Air Dispersion Modeling Overview

Overview

As part of the air permitting process, facilities in South Carolina are required to demonstrate that the emissions coming from their sources will not cause the violation of any applicable South Carolina air pollution control regulations or standards. It is a required part of many air construction permits (including all Prevention of Significant Deterioration (PSD) construction permits) and some Title V, conditional major, and state operating permits and renewals.

These forms are intended for guidance purposes only and may not be applicable to all facilities. Some forms require manipulation so that spreadsheets represent materials used at your facility.
