Project  Summary
Solvent Chemical  Inventory of
the Newark AFB  Building  4
Facility
P.J. Brewer, A.S. McElligott, and J. Ayer
   A solvent chemical  inventory was
performed at Newark AFB to develop a
chemical usage profile of the Building 4
facility, and identify primary sources of
solvent emissions. This survey was per-
formed in two parts. Part 1 consisted of
a chemical inventory survey which de-
fined solvent chemical usage rates and
locations. Part 2 was the development
of a mass balance profile for the two
most commonly used solvents:  1,1,2-
trichloro-1,2,2-trifluoroethane (CFC-113)
and 1,1,1-trichloroethane (TCA). The re-
sults of the mass balance efforts were
used to identify significant CFC-113 and
TCA emission sources  and develop  a
test matrix for quantifying solvent emis-
sions from the identified sources. It was
found that nearly all of the CFC-113 is
lost from sources that are vented either
directly to the atmosphere or to poorly
operated solvent vapor recovery sys-
tems.
   This  Project Summary was devel-
oped by EPA's Air and Energy  Engi-
neering Research Laboratory, Research
Triangle Park, NC, to announce key find-
ings of the research project that is fully
documented in a separate report of the
same title (see Project Report ordering
information at back).
