1.2 OVERVIEW OF THE ISC MODELS
This section provides an overview of the ISC models, including a discussion of the regulatory applicability of the models, a description of the basic options available for running the models, and an explanation of the basic input data and hardware requirements needed for executing the models.
1.2.1 Regulatory Applicability
The U.S. Environmental Protection Agency (EPA) maintains the Guideline on Air Quality Models (Revised) (hereafter referred to as the "Guideline") which provides the agency's guidance on regulatory applicability of air quality dispersion models in the review and preparation of new source permits and State Implementation Plan (SIP) revisions. Regulatory application of the ISC models should conform to the guidance set forth in the Guideline, including the most recent Supplements. Any non‑guideline application of the models should meet the requirements of the applicable reviewing agency, such as an EPA Regional Office, a State or a local air pollution control agency. In general, regulatory modeling applications should be carried out in accordance with a modeling protocol that is reviewed and approved by the appropriate agency prior to conducting the modeling. The modeling protocol should identify the specific model, modeling options and input data to be used for a particular application.
 The Guideline is published as Appendix W to 40 CFR Part 51.
