United States Environmental Protection Agency Air and Energy Engineering • Research Laboratory / / Research Triangle Park NC 27711 Research and Development EPA/600/S9-85/015 June 1985 &ER& Project Summary Proceedings: First Annual Acid Deposition Emissions Inventory Symposium James B. Homolya, Compiler A 2-day symposium, on the progress of implementing the National Acid Precipitation Assessment Program (NAPAP) Task Group B's emission inventory programs, was intended pri- marily for government, academic and private sector individuals involved in either the development or use of at- mospheric emission inventories for acid deposition and air quality research. Topics included the development of emission factors for a wide range of pollutant emissions and the use of detailed emission inventories for atmos- pheric transport, transformation, and deposition modeling. The meeting: (1) provided detailed. presentation and information transfer of the NAPAP emission inventory pro- gram; (2) illustrated and strengthened the relationship between the emission inventory data base and its users; and (3) compared and contrasted the NAPAP emission inventory with other on-going emission inventory develop- ment programs. This Project Summary was developed by EPA's Air and Energy Engineering Research Laboratory, Research Triangle Park, NC. to announce key findings of the research project that is fully docu- mented in a separate report of the same title (see Project Report ordering infor- mation at back). Background The proceedings document presen- tations during a symposium (cosponsored by EPA and the Department of Energy), held December 3-4,1984, in Raleigh, NC. I n 1980, Congress established the Nation- al Acid Precipitation Assessment Program (NAPAP) to coordinate and expand re- search relevant to the problems posed by acid deposition in and around the U.S. The program is organized and managed through the Interagency Task Force on Acid Precipitation (ITFAP) and 10 subor- dinate task groups coordinating specific technical areas of research. One of these 10 groups is Task Group B, Man-Made Sources, chaired by a representative of the Office of Fossil Energy, Department of Energy (DoE). The task group includes members representing the Environmental Protection Agency, the Tennessee Valley Authority, and the National Laboratory Consortium. Major objectives of Task Group B are to: 1. Provide an accurate and complete inventory of emissions from an- thropogenic sources believed to be important in acid deposition pro- cesses. The inventories are to be provided with adequate geographic, temporal, and sectoral resolution. 2. Provide models which predict how acidic and acid-precursor emissions may be altered by factors such as economic growth, fuel supply, emissions regulations, and control techniques. These models will have the capability to permit the calcula- tion of alternative control strategies. The 2-day symposium discussed the progress in the implementation of the Task Group B emission inventory pro- grams. J. David Mobley of EPA's Air and Energy Engineering Research Laboratory was Symposium Chairman, with planning ------- and coordination support from John Fink, of EPA's Office of Air Quality Planning and Standards, and Edward Trexler, of DoE's Office of Fossil Energy. The sym- posium focused on the National Acid Precipitation Program Task Group B's development of a comprehensive emis- sions inventory for use in acid deposition research. The meeting was intended primarily for government, academic, and private sector individuals involved in either the development or use of atmos- pheric emission inventories for acid de- position and air quality research. Topics included the development of emission factors for a wide range of pollutant emissions and the use of detailed emis- sion inventories for atmospheric trans- port, transformation, and deposition modeling. The following presentations were made on NAPAP emission inventory activities, application of emission inven- tories for scientific purposes, and related emission inventory development projects.

Benkovitz, Brook- haven National Laboratory The meeting was attended by 104 people, representing an excellent cross- section of the target audience. Foreign representatives to the meeting were from Canada, the Netherlands, and the United Kingdom. The meeting: 1. Provided detailed presentation and information transfer of the NAPAP emission inventory program, 2. Illustrated and strengthened the relationship between the emission inventory data base and its users, and 3. Compared and contrasted the NAPAP emission inventory with other on-going emission inventory development programs. Handout material provided at the meet- ing included a brief summary of each presentation. Copies of the papers are available as the meeting proceedings, along with a list of registrants. ------- J.
