In complex terrain situations, where the stack exhaust is at or below the height of nearby terrain features, EPA (1990) recommends various screening techniques to evaluate plume impact during stable conditions. The preferred screening techniques are: (1) Valley; (2) CTSCREEN; (3) COMPLEX I; (4) SHORTZ/LONGZ; and (5) Rough Terrain Dispersion Model (RTDM). If these screening techniques demonstrate a possible exceedance of the NAAQS, EPA suggests that a more refined analysis may need to be conducted. The Complex Terrain Dispersion Model Plus Algorithms for Unstable Situations (CTDMPLUS) is the EPA preferred air quality model for this situation. This paper discusses the dispersion models, the wind tunnel modeling methodology, and the comparison between the screening model and wind tunnel concentration predictions.
