Presents a quantitative assessment of the control costs and emission reductions that might be expected from then current EPA policy and from three Congressional alternatives introduced in Congress in 1987-8.  VOC control cost model input data and calculation procedures are described in Chapter II, which also discusses the base year emission inventories, control cost equations, growth projections, emission constraints, and results reporting.  Chapter III presents similar information for the CO model.  Although a model was not developed for the NOx control cost analysis, organization of the NOx emission data base and development of NOx control cost equations are explained in Chapter IV.  Chapters V through VIII present analysis results for all four policy alternatives. Summary results for all alternatives are presented in Chapter IX.  Because CO control costs are much lower that those for VOC and NOx, they are only reported in Chapter IX.  Because the results are sensitive to the growth rates used in the VOC model, a sensitivity analysis is performed and reported in Chapter X.  Key analysis caveats are delineated in Chapter XI.
