GENERAL
SUBJECT
:
Dioxins
at
OCPSF
Sites
TOPICS
DISCUSSED
AND
ACTION
TAKEN
I
called
Gary
Amendola
to
discuss
some
findings
on
dioxins
and
the
chlorine
chemical
industry.

Mr.
Amendola
discussed
dioxins
treatment
control:

For
EDC/
VCM
producing
sites,
most
perform
some
form
of
steam
stripping
for
volatile
pollutants
prior
to
biological
treatment.
Some
sites
prevent
their
filter
bottoms
from
entering
the
biological
treatment,
and
this
can
reduce
the
amount
of
dioxin
in
the
wastewater.

Plants
with
the
chlor/
alkali
process
isolate
the
chlorine
gas
condensates,
routing
them
through
GAC
canisters
to
removed
dioxin.
Sometimes
treatment
of
these
condensates
requires
2
or
3
beds
in
series,
if
the
flow
is
large
enough.

PVC
manufacturing
does
not
generate
nearly
as
much
dioxin
as
the
chlor­
alkali
plants
or
manufacture
of
EDC/
VCM.
Suspension
PVC
plants
are
more
common,
and
dispersion
PVC
plants
less
common.
Sites
manufacturing
PVC
co­
located
with
other
processes
usually
treat
their
wastewater
with
biological
treatment
and
solids
removal.
Because
dioxin
is
hydrophobic
it
adsorbs
to
solids.
Thus,
extensive
solids
removal
would
remove
more
dioxin.

I
asked
Mr.
Amendola
if
he
knew
when
the
2000
Dioxin
Inventory
data
would
be
available
for
the
Chlorine
Chemical
Industry.
He
said
unfortunately,
with
industry
carefully
verifying
their
information,
some
companies
had
still
not
gotten
information
to
him.
He
estimated
that
the
data
would
be
available
sometime
in
late
February.
