Subject
TWPEs
for
Dioxin/
Furan
Releases
from
SIC
Code
2491
Facilities
Mr.
Johnston:

I
am
writing
on
behalf
of
the
Pentachlorophenol
Task
Force
(
Task
Force)
concerning
the
Toxic
Weighted
Pounds
Equivalents
(
TWPE)
for
dioxin/
furan
releases
from
penta
wood
treating
facilities
in
SIC
Code
2491.
In
the
Timber
Industry
memo
that
you
provided
to
us
on
June
8,
2004,
the
TWPE
for
dioxin
and
dioxin­
like
compounds
for
facilities
within
SIC
Code
2491
was
calculated
at
379,324
pounds
equivalent.
Since
that
time,
EPA
has
published
revisions
to
the
Toxic
Weighing
Factors
(
TWFs)
for
Dioxins
and
Congeners
(
August
10,
2004
Zipf
Memo).
Also,
the
PTF
has
obtained
additional
analytical
data
on
the
dioxin
and
furan
content
of
technical
pentachlorophenol
(
penta).
As
explained
below,
these
two
developments
lead
to
a
recalculation
of
the
TWPE
for
dioxins
and
dioxin­
like
compounds
for
facilities
in
SIC
Code
2491.
The
recalculated
TWPE
is
41,481.

1.
High
Resolution
Gas
Chromatography/
Mass
Spectral
Analysis
of
the
Dioxin
Content
of
Penta.

In
compiling
the
Y2000
TRI
reports
for
dioxin
and
dioxin­
like
compounds,
facilities
within
SIC
Code
2491
utilized
available
data
on
penta
concentrations
in
stormwater
effluent.
This
was
typically
a
single
grab
sample
taken
30­
minutes
after
a
rain
fall
event
pursuant
to
the
facilities'
general
stormwater
permits.
Factors
for
converting
penta
levels
to
dioxin
and
furan
levels
were
then
applied.
The
penta­
to­
dioxin
and
furan
conversion
factors
were
based
on
supplier­
provided
data
on
the
dioxin
and
furan
content
in
penta.
The
supplier
data
were
such
that
it
permits
an
estimated
TM­
17
breakdown
only
by
the
individual
2,3,7,8­
substituted
dioxin
and
furan
congener
groups,
but
not
a
further
differentiation
of
the
specific
isomers
within
a
given
congener
group.
Thus,
for
example,
the
two
2,3,7,8­
heptachlorodibenzofuran
isomers
(
1,2,3,4,6,7,8­
and
1,2,3,4,7,8,9­)
were
assumed
to
be
present
in
equal
amounts
because
no
data
were
available
to
allow
a
further
differentiation.

In
connection
with
the
reregistration
of
penta,
the
Task
Force
commissioned
a
state­
of­
the­
art
High
Resolution
GC­
MS
of
the
TM­
17
content
of
penta
by
the
Alta
Analytical
Laboratory.
The
results
of
the
analysis,
which
have
been
provided
to
the
Office
of
Pesticide
Programs,
are
attached.
The
penta
sample
is
designated
PETDC01A
in
the
analytical
report.
The
analysis
permits
a
revised
and
more
accurate
distribution
of
the
specific
TM­
17
compounds
in
penta.
It
should
be
noted
that
for
chemical
reasons
not
all
of
the
possible
TM­
17
compounds
are
coproduced
during
penta
manufacture.
As
such,
certain
TM­
17
compounds
are
Non­
detected
in
the
Alta
analysis
and
are
assigned
a
Zero
value
in
the
TM­
17
distribution.

2.
Recalculation
of
TWPE
for
Dioxin
and
Dioxin­
like
Compounds
The
attached
Excel
spreadsheet
provides
a
recalculation
of
the
TWPE
for
releases
of
dioxin
and
dioxin­
like
compounds
to
surface
water
reported
by
facilities
within
SIC
Code
2491
in
the
Y2000
TRI.
The
recalculation
reflects:
(
1)
the
revised
TWFs
for
Dioxins
and
Congeners
as
set
forth
in
the
August
10,
2004
Zipf
Memo,
and
(
2)
the
refined
TM­
17
distribution
for
those
dioxins
and
furans
found
in
penta
as
reflected
in
the
High
Resolution
GC­
MS
by
the
Alta
Analytical
Laboratory.
The
recalculated
TWPE
for
the
SIC
code
is
41,481.
3.
Task
Force­
Commissioned
Guidance
Document
for
TRI
Reorting
of
Dioxins
and
Dioxin­
like
Compounds
At
our
August
meeting,
you
asked
for
a
copy
of
the
guidance
used
by
facilities
within
SIC
Code
2491
to
prepare
TRI
reports
for
dioxin
and
dioxin­
like
compounds.
A
copy
is
being
provided
to
you
by
mail.

4.
Request
for
Follow­
up
Meeting
We
have
previously
discussed
a
follow­
up
meeting
for
sometime
this
fall
to
review
additional
data
on
releases
of
dioxin
and
furans
from
the
industry
sector.
The
Task
Force
requests
that
such
a
meeting
be
held
in
mid­
December,
2004
at
which
time
we
expect
to
have
additional
data
on
penta
concentrations
in
stormwater
effluent
to
share
with
the
Agency.
Kindly
advise
as
to
your
availability
for
the
meeting.
Also,
we
would
request
that
the
meeting
be
limited
to
penta
and
dioxin
and
dioxin­
like
compounds
in
order
to
focus
specifically
on
those
data.

I
thank
you
for
your
time.
