Re:
your
question:

"
PS
­
Did
not
hear
back
from
TJ
Finseth
re:
our
Titanium
Dioxide
plant
data
submittal.
Have
you
received
any
feedback
from
him?
Assume
it
satisfied
the
current
request.
We
still
plan
to
submit
supplemental
(
primarily
more
recent)
data
and
are
having
a
conference
call
with
our
plants
next
Monday
to
discuss
this."

The
answer
is
that
we
do
not
need
any
more
information
on
the
Dupont
TiO2
plants
at
this
time.
We
do,
however,
have
a
few
questions
regarding
the
DuPont
Chamber
Works
facility
in
Deepwater,
NJ.
I
would
appreciate
it
if
you
could
answer
these
questions
or
could
forward
them
on
to
the
appropriate
person.
Thank
you.

1.
Where
do
the
discharges
of
chlorine,
heptachlor
and
pendimethalin
originate
from?
Is
it
from
plant
operations
(
manufacturing
processes)
or
from
the
centralized
waste
treatment
plant?
Are
the
pesticides
coming
from
off­
site
or
on­
site
wastewater?

2.
Does
DuPont
Chambers
Works
report
any
heptachlor
discharges
in
its
DMRs?

3.
What
other
chemicals
are
reported
released
(
to
TRI
or
PCS/
the
state)
from
the
CWT
plant?

Please
send
