The report presents the model framework used to estimate state level and national future volatile organic compound (VOC) emissions and control costs for stationary industrial and utility sources. The framework involves a projection approach using the 1980 National Acid Precipitation Assessment Program (NAPAP) inventory for VOC emissions aggregated by 101 defined source categories apportioned by ozone attainment and nonattainment areas for each state. The projection approach involves applying expected industry activity factors (growth/decline/replacement-rates) and emission constraint factors (environmental control reductions) to the base year emission levels. Future year uncontrolled and controlled VOC emissions and annualized control costs are estimated using annualized control cost values (1980 dollars/ton) for each source category. The model has five data files which interact to provide uncontrolled/controlled VOC emission projections and cost controls for: any year from 1980 to 2030; 49 geographic regions (48 contiguous states and the District of Columbia); and 90 industrial/utility point source categories and 11 industrial area sources.
