Introduction to the ISC2 Model

The Industrial Source Complex Model (ISC2) is a steady-state Gaussian plume model which can be used to assess pollutant concentrations from a wide variety of sources associated with an industrial source complex. This model can account for the following: settling and dry deposition of particals; downwash; area; lone and volume sources; plume rise as a function of downwind distance; separation of point sources; and limited terrain adjustment. It operates in both long-term and short-term modes. And allows the user to select either Urban and Rural dispersion coefficients. Chemical transformations are treated by using first order exponential decay.
