Updated
inputs
for
Sony
Maria,

Dave
and
I
have
talked
with
Mark
Farmer
of
Sony,
and
he
is
going
to
e­
mail
us
th
e
coordinates
for
the
emission
points.
Until
then,
I
am
sending
you
the
rest
of
the
revised
inputs
for
Sony
(
along
with
the
inputs
for
the
other
magnetic
tape
facilities).

As
I
mentioned
during
our
call,
there
are
two
processes
at
the
Sony
plant
which
are
emitting
HAP:
(
1)
an
advanced
metal
evaporation
(
ME)
process
(
which
uses
met
allic
cobalt)
and
(
2)
a
conventional
magnetic
tape
process
(
which
uses
MEK,
tolu
ene,
and
cobalt­
doped
iron
oxide­­
with
cobalt
only
2­
3
weight
percent
of
the
mix
).
The
ME
process
is
located
in
the
ME
Plant,
which
is
at
the
bottom
of
the
Son
y
plant
diagram.
The
conventional
process
is
located
in
the
P­
1
and
P­
2
Plants,
which
are
near
the
center
of
the
Sony
plant
diagram.

As
I
mentioned,
I
have
adjusted
the
cobalt
and
cobalt
compound
emission
estimate
s
based
on
the
information
from
Sony
(
i.
e.,
used
3
percent
of
the
TRI
cobalt
com
pound
emissions
and
used
the
adjusted
2000
metallic
cobalt
emission
estimate
fro
m
Sony­­
0.29
tpy).

Let
me
know
if
you
have
any
questions.
