Project  Summary
Proceedings:  Second  Annual
Acid  Deposition  Emission
Inventory  Symposium
(November  1985)
J.B. 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:
