GENERAL
SUBJECT
:
Dioxin
Releases
TOPICS
DISCUSSED
AND
ACTION
TAKEN
On
November
13,
2003,
I
spoke
with
Scott
Pleskonko
of
PPG
Industries,
Inc.
concerning
the
release
of
dioxin/
dioxin­
like
compounds
to
surface
waters
by
PPG
Industries,
Inc.
in
2000.
PPG
Industries,
Inc.
reported
a
release
of
2.8
grams
of
dioxin/
dioxin­
like
compounds
to
the
Ohio
River
on
there
2000
Toxic
Release
Inventory
(
TRI)
Form
R.
Forty­
two
percent
of
that
amount
was
the
two
least
toxic
of
the
17
dioxin/
dioxin­
like
congeners
on
Form
R
Mr.
Pleskonko
said
that
the
source
of
the
dioxin
is
process
water
from
the
manufacture
of
chlorine.
The
chlorine
process
is
operated
365
days
per
year.

Mr.
Pleskonko
confirmed
that
monitoring
data
and
measurements
were
used
to
determine
the
amount
of
dioxin
released
to
the
Ohio
River
by
PPG
Industries.
He
said
that
wastewater
samples
from
three
process
streams
were
collected
and
analyzed
for
dioxin.
When
the
sample
results
were
reported
as
non
detected,
the
value
for
one
half
of
the
detection
limit
was
used
to
calculate
the
mass
of
dioxin
released.
The
estimated
flow
rates
for
the
process
streams
were
200,000
gallons
per
day
(
gpd),
10,000,000
gpd,
and
20,000,000
gallons
per
day
for
a
total
plant
process
flow
rate
of
30.2
million
gallons
per
day.
The
concentration
of
dioxin
in
the
release
to
the
Ohio
River
is
20
ng/
l.

Based
on
the
results
of
my
conversation
with
Mr.
Pleskonko,
the
reported
release
of
dioxin
to
the
Ohio
River
by
PPG
Industries
in
2000
is
a
valid
number
and
should
be
included
in
the
2000
estimated
pollutant
loads
and
Total
Weighted
Pound
Equivalent
(
TWPE)
loads
for
the
inorganic
chemicals
manufacturing
industry.
