Hello
TJ:

Just
to
follow
up
on
our
conversation
today:­

Kodak's
TRI
data
for
2002
for
both
D/
Fs
and
total
PACs
was
based
upon
analyses
of
sludge
from
our
wastewater
treatment
facility
and
estimations
of
the
concentration
of
solids
in
the
effluent.

As
I
mentioned
for
D/
Fs,
some
more
recent
analyses
of
the
effluent
have
confirmed
that
our
estimates
for
these
materials
were
very
representative.

For
PACs,
we
don't
have
very
much
profile
data
to
go
on.
We
have
a
single
study
(
1995)
that
looked
at
three
samples
of
sludge
at
one
time
point,
but
we
wouldn't
regard
these
to
be
representative
of
a
typical
profile.

Hope
this
(
finally!)
answers
your
questions,
and
sorry
for
the
earlier
confusion.

Regards,
