EPA
ECA
Proposal
for
Fluoropolymer
Incineration
Testing
Rationale
Incineration
testing
of
fluoropolymers
and
fluoropolymer
treated
articles
was
not
included
in
the
FMG
LOI
commitments.
The
degradents
of
perfluorinated
materials
vary
greatly
as
a
function
of
incineration
temperature
and
residence
time.
Thermodynamically,
at
a
temperature
of
about
1200
°
C
a
destruction
efficiency
of
99.99%
for
a
C­
F
chemical
bond
can
be
obtained.
Information
on
the
extent
of
destruction
and
full
characterization
of
the
types
of
degradents
formed
at
lower
incineration
temperatures
is
unknown.
This
is
further
confounded
because,
based
on
US
information,
there
are
three
types
of
incinerators
in
operation
across
the
US:
1)
medical
waste
incinerators
operating
around
650
°
C;
2)
municipal
waste
incinerators
(
static
grate)
operating
between
400­
600
°
C;
and
3)
chemical
(
hazardous
waste)
incinerators
operating
up
to
1300
°
C;
and
it
is
expected
that
the
extent
of
destruction
and
types
of
degradents
will
vary
across
each
incinerator
type.

ECA
Proposal
It
is
proposed
that
incineration
testing
be
conducted
to
meet
the
following
data
needs:
<
Define
by
test,
the
temperature
needed
to
provide
99.99%
destruction
of
each
perfluorinated
test
substance/
material,
both
as
the
manufactured
perfluoro
compound
and
the
article
employing
the
perfluoro
compound.
<
Create
an
incineration
temperature
profile
versus
characterized
degradants
Test
substances:
<
Tier
1:
EPA
recommends,
as
a
starting
point,
that
testing
be
conducted
for
each
of
the
12
fluoropolymer
products
identified
by
FMG.
<
Tier
2:
Depending
on
test
results,
an
additional
representative
number
of
product
formulations
and
articles
in
commerce
may
need
to
be
tested.
EPA
recommends
that
the
formulations
and
articles
be
determined
by
members
of
a
technical
subgroup
on
Incineration
Testing.

Test
Method:
Testing
is
to
be
conducted
using
methods
equivalent
to
those
described
or
reviewed
in
"
Guidelines
for
Determination
of
Poly­
halogenated
Dibenzo­
p­
dioxins
and
Dibenzofurans
in
Commercial
Products"
(
see
40CFR,
section
766.1
through
766.18)
and/
or
the
3M
protocol.

Although
the
average
residence
time
may
vary
across
incinerators,
testing
under
this
ECA
proposal
should
satisfy
a
2
second
residence
time.
Incineration
testing
within
these
three
(
3)
temperature
ranges
will
provide
data
that
is
crucial
in
determining
potential
pathways
into
the
environment
of
perfluoro
compounds
and
their
degradants
which
may
be
precursors
to
PFOA.

The
laboratory
equipment
needed
to
define
temperatures,
residence
times
and
byproducts
produced
includes
a
high
temperature
tubular
furnace
with
carrier
gas
connected
to
a
gas
chromatograph
followed
by
a
mass
spectrometer.
Note:
a
GC­
GC­
MS
arrangement
will
likely
be
necessary
for
sub­
ppm
data
generation.
Thermogravimetric
analysis
will
be
used
before
initiating
the
laboratory
incineration
testing
to
document
the
low
temperature
(<
500
°
C)
behavior
of
the
test
compounds
(
or
articles)
and
to
verify
gasification
of
material
following
ASTM
E1641,
Decomposition
Kinetics
by
Thermogravimetric
Analysis.

EPA
GLP
Data
Quality
and
Quality
Assurance
Requirements:
All
testing
must
conform
with
EPA
GLP
Data
Quality
and
Quality
Assurance
requirements.

Data
Reporting:
The
final
report
on
each
test
substance
tested
must
include
a
detailed
description
of
the
specific
test
conditions
used,
the
test
data
including
any
associated
calculations,
spectra
and
curves.
Details
of
specific
data
to
be
reported
shall,
at
a
minimum,
include
information
similar
to
those
outlined
under
40
CFR,
section
761.70
for
Incineration.

°
Objective:
Determination

byproducts
of

°
The
industry
group
recommends
that
incineration
testing
be
included
in
an
ECA
°
To
facilitate
the
creation
of
an
ECA
for
incineration
testing
the
industry
group
recommends
the
following;

 
Using
the
3M
incineration
protocol
as
a
model,
the
industry
group
will
develop
a
protocol
and
submit
it
for
review
by
the
interested
parties
 
The
interested
parties
will
review
the
protocol
and
submit
questions
 
The
protocol
will
be
finalized
in
a
technical
meeting
to
be
scheduled
21
ECA
Framework
Item

°
Objective:

°
The
industry
group
suggests
that
Framework

can
not
be
discussed
until
the
completion
of
incineration
testing
called
for
in

Industry
submitted

for

polymers
P­

on
June

The
industry
group
proposes
the
following
°
Similar
P­
chem
property
documents
will
be
prepared
for
remaining
Fluoropolymers
and
Fluoroelastomers
and
submitted
by

°

to
submit

document
by

°
Based
on
the
data
submitted
for
PTFE,
FEP,
and
PFA,

Framework
Item
2
is
complete
for
those
materials
°
With
the
submittal
of
the
data
for
APFO
and
other
polymers,
and
subsequent
review
by
the
interested
parties,

Item
2
will
be
then
be
evaluated
for
completion
23
ECA
Framework
Item
3
°
Objective:
elucidation
of
degradation
pathways
and
identification
of
degradation
products
°
Based
on
the
data
submitted
for
PTFE,
FEP,
and
PFA
in
Framework
Item
2,
the
industry
group
suggests
that
Item
3
is
not
relevant
to
the
study
of
"
outstanding
PFOA
source
and
exposure
questions."

The
industry
group
proposes
the
following
°
Interested
parties
review
the
data
submitted
in
Item
2
and
the
suggestion
that,
based
on
the
data,
Item
3
is
not
relevant.

°
If
technically
based
questions
can
not
be
adequately
answered
by
technical
professionals,
then
additional
testing
would
be
considered
in
an
ECA.

°
If
it
is
concluded
that
the
industry
suggestion
is
valid,
then
Framework
Item
3
will
be
considered
complete
for
PTFE,
FEP,
and
PFA.

°
The
same
review
process
will
be
followed
for
the
remaining
fluoropolymers
and
fluoroelastomers
when
the
data
is
submitted
for
Framework
Item
2.

products
°
Based
on

for
PTFE,

and

in
Framework
Item
2,
the
industry
group
suggests
that
Item
4
is
not
relevant
since
these
polymers
are
stable
and
do
not
degrade
via
normal
degradation
pathways
25
ECA
Framework

4
The
industry
group
proposes
the
following
°
Interested

review
the

the
suggestion
that,
based
on
the
data,
Item
4
is

If
