Mission
Statement:
The
Telomer
Workgroup
will
develop
ECA
proposal(
s)
for
telomers
and
telomer­
treated
products
as
identified
by
the
Plenary
Group.
The
initial
focus
will
be
for
the
data
needs
identified
in
items
2,
3,
4,
5,
6,
7,
8,
9,
and

of
the
Preliminary
Framework
document
prepared
by
EPA,
specifically
addressing:
(
a)
P­
chem
properties
to
inform
fate
testing
for
telomer
chemicals
not
included
in
the
industry­
sponsored
LOI;
(
b)
elucidation
of
degradation
pathways
and
identification
of
degradation
products;
(
c)
determination
of
pchem
fate
and
transport
properties
of
major
degradation
products;
(
d)
determination
of
incineration
byproducts
of
telomers
and
telomer­
treated
products
and
articles;
(
e)
determination
of
p­
chem,
fate
and
transport
properties
of
major
incineration
byproducts;
(
f)
presence/
quantification
of
PFOA
precursors
in
telomer
chemical
products
and
in
telomertreated
or
telomer­
containing
products
and
articles;
(
g)
presence
of
PFOA
precursors
emitted
from
telomer­
treated
products
and
articles
as
they
age
during
use;
and
(
h)
product
stewardship
information.

Meeting
Objective:
Development
meeting
to:
1.
Clarify
the

topics
for
ECA
development.
2.
Discuss
and
develop
an
ECA
proposal
for
incineration
testing.
3.
Discuss
additional
ECA
candidate
topics
and
develop
initial
proposals.
4.
Prepare
workgroup
presentation
to
plenary
session
and
select
spokesperson.
5.
Identify
workgroup
next
steps
and
assignments.

EPA
ECA
Proposal
for
Telomer
Incineration
Testing
Rationale
Incineration
testing
of
telomers,
telomer
products,
and
articles
treated
with
telomers
containing
perfluoroalkyl
groups
was
not
included
in
the
TRP
LOI
commitments.
The
degradants
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
degradants
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
degradants
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
products
TRP
committed
to
PFOA
testing
for
the
LOI.
Tier
2:
Depending
on
test
results,
specifically
whether
higher
C
chain
length
(
C8
typically)
acids
form,
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
Polyhalogenated
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,
as
specified
under
Rationale
section
above,
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
(

to

Requirements:

Data
Reporting:

substance
tested
must

used,
the
test

Incineration
:
Study
Approach

TRP
has
agreed
to
study
the
applicability
of
incineration
to
its
Telomer­
treated
products
and
related
articles
in
the
US
in
a
"
desk
study"

Initial
steps
will
be
to
first
understand
the
US
disposal
methods
and
in
what
markets
incineration
is
applicable

Second
review
the
US
incinerator
conditions
to
understand
permitted
temperatures
and
compare
with
known
Telomer
degradation
temperatures

The
"
desk
study"
will
define
the
scope.
The
design
of
the
study
and
nature
of
the
methodology
needs
to
be
discussed
to
measure
PFOA
emissions
from
incineration
of
telomertreated
articles
