Homolya and P.A. Cruse The 2-day symposium discussed pro- gress made by the National Acid Precip- itation Assessment Program and other organizations in the development of emission inventories. The symposium was sponsored by EPA's Air and Energy Engineering Research Laboratory, in cooperation with EPA's Office of Air Quality Planning and Standards, the U.S. Department of Energy, the Na- tional Oceanic and Atmospheric Ad- ministration, and the National Acid Pre- cipitation Assessment Program. The meeting was intended primarily for government, academic, and private sector individuals involved in the devel- opment or use of emission inventories for acid deposition. Topics addressed at the meeting included historical emis- sions estimates, the 1980 and 1985 emission inventories, Eulerian model- ing analyses, and uncertainties in emis- sion inventories. The proceedings pro- vide valuable documentation of results of efforts to date to develop emission factors and emission inventories for an- thropogenic and natural sources. This Project Summary was devel- oped by EPA's Air and Energy Engineer- ing Research Laboratory, Research Tri- angle Park, NC, to announce key findings of the research project that is fully documented in a separate report of the same title (see Project Report or- dering information at back). The Symposium The Second Annual Acid Deposition Emission Inventory Symposium was held in Charleston, SC, November 13- 14, 1985. The purpose of the meeting was to discuss progress made by the National Acid Precipitation Program (NAPAP) in development of emission inventories for use in acid deposition re- search. EPA's Air and Energy Engineer- ing Research Laboratory sponsored the symposium with support from EPA's Office of Air Quality Planning and Standards, DOE, NOAA, and NAPAP. The 72 attendees included representa- tives of EPA, DOE, NOAA, state air pol- lution control agencies, several univer- sities, and the private sector. The symposium consisted of five ses- sions. Robert Friedman, Office of Tech- nology Assessment, U.S. Congress, de- livered the keynote address on regulatory and legislative needs related to emission inventories. Session chair- men and speakers were: Welcome and Introduction Michael A.
