As part of the environmental assessment of the US Department of Energy's Fifth National Energy Policy Plan (NEPP-5), Argonne National Laboratory projected emissions of sulfur dioxide (SO/sub 2/) and nitrogen oxides (NO/sub x/) out to the year 2030 and emissions of volatile organic compounds (VOC) to the year 2010. The projections indicated changes in emissions at the national level, but, more significantly, suggested a fundamental shift in regional emission patterns over the next 50 years. This paper examines the regional and sectoral distribution of these projected emissions and relates them to potential changes in deposition levels over the next 50 years. Specifically, changes in sulfur deposition in five sensitive areas are examined with the ASTRAP model of atmospheric transport, transformation, and deposition. Expected changes in regional emissions of NO/sub x/ and VOC are also presented, but their implications for deposition cannot be assessed quantitatively at this time due to limitations in the capabilities of current long-range transport models. 11 refs., 9 figs., 1 tab.
