Expert interface for modeling air quality impacts from superfund sites

Abstract

The Expert Interface software program aids the novice user in choosing the correct release scenario and specifying the inputs required by the EPA Industrial Source Complex (ISC) air dispersion model. This innovative system provides a framework so that users follow consistent methodologies for modeling various release scenarios. This is achieved through the use of a graphical interface that includes a query methodology enabling the program to identify the release scenario and ask appropriate questions for more details. In this paper we describe the design, implementation, capabilities and use of the Expert Interface for Superfund applications. The Expert Interface program is written in Microsoft Visual C++ for the Windows environment. For illustration purposes, this phase of the development considers two source categories. The generic source category consists of a point source, while the Superfund category includes a lagoon source. For each source type the program queries the relevant variables from the user. In addition, the Expert Interface asks questions regarding control options, receptors, meteorology and output formats. The Expert Interface then creates the input file required by the ISC dispersion model. Finally, the Expert Interface enables the user to run the ISC model and browse the results file.
