Following previous tentative identification of the computer program packages LIRAQ and ADPIC as useful for application in studying air quality processes in the region of the Athabasca Oil Sands, this report examines these models in greater detail. After a brief examination of the relevant conditions in the area to identify possible (or necessary) simplifications each model is examined in detail. For the LIRAQ program package it is concluded that the model assumptions are too restrictive for application to this problem. The ADPIC program package is found to be more applicable although reactive pollution photochemistry is not handled. The relatively low computer capacity currently available in Canada makes application of this model computationally impractical. A modified version of the ADPIC code, acronym PATRIC, is identified as having potential for AOSERP although the code would need to be almost completely restructured to overcome current physical and computer limitations.
