The National Acid Precipitation Assessment Program (NAPAP) was established by Congress in 1980 to coordinate and expand research relevant to acid deposition in North America. The Interagency Task Force on Acid Precipitation (ITFAP) manages the program through eight subordinate task groups that coordinate specific technical areas of research. Task Group I coordinates the research in the areas of man-made pollution sources and their control technologies. A major goal of Task Group I is the development and maintenance of detailed inventories of anthropogenic emissions. The Acid Deposition Emission Inventory Plan, prepared as one of the EPA contributions to Task Group I, identifies the need for emissions inventories of current base years to support both assesment activities and the development, evaluation and use of long-range transport and transformation models. The uncertainty estimates of emissions data are an integral part of the inventory. In a previous project, a basic statistical framework was developed to assess the uncertainties associated with the emissions data as presented in the NAPAP emissions inventory. Work has continued in two parallel directions: adaptation of the statistical methodologies previously developed for use in conjunction with the NAPAP 1980 base year inventory and continued study of the sources of uncertainty in the NAPAP 1985 base year emissions calculation, with development of statistical methodologies to properly account for these uncertainties. This report details the work accomplished during FY 1986. 7 refs., 3 tabs.
