The results of using three different types of models to assess the potential effectiveness of ozone control strategies are described. Data collected during the RAPS program conducted in St. Louis were used to develop inputs for a complex photochemical air quality simulation model. The model was used to simulate a number of control strategies to establish their potential for lowering ozone levels. These strategies were replicated with two simpler models - City-specific and Rollback. The results obtained with the simpler models were then compared to those found with the more complex model. Neither of the simpler models agreed with the complex under all conditions. However, in estimating the degree of control necessary to reduce peak ozone to the level of the national standard, the differences between the complex model and City-specific EKMA were usually less than 10%. Differences between Rollback and the complex model were usually less than 20%.
