The
purpose
of
the
workshop
is
to
discuss
the
molecular
induction

pathogenesis,
and
the
extrapolation
of
a
dose

relationship.
Expert
panelists
will
discuss
the
following
topic
areas:
Molecular,
chemical

biochemical
mechanisms
of
asbestos
fiber
toxicity;
mechanisms
of
fiberinducing
lung

pleural
disease;
and
exposure

SUPPLEMENTARY
INFORMATION:
EPA's
current
assessment
of
asbestos
toxicity
is
based
primarily
on
an
asbestos
assessment
completed
in
1986,
and
EPA's
assessment
has
not
changed
substantially
since
that
time.
However,
since
1986,
there
have
been
substantial
improvements
in
asbestos
measurement
techniques
and
in
the
understanding
of
how
asbestos
exposure
contributes
to
disease.
To
incorporate
the
knowledge
gained
over
the
last
17
years
into
the
agency's
toxicity
assessment
for
asbestos,
EPA
is
interested
in
reviewing
the
most
up­
to­
date
peer
review
literature
on
the
mechanisms
of
asbestos
toxicity.
The
experts
will
include
scientists
with
extensive
expertise
in
relevant
fields,
such
as
mechanistic
toxicology,
pulmonology
toxicology,
and
risk
assessment.
The
panelists
will
be
asked
to
respond
to
several
questions
that
address
key
issues,
including
interpretations
of
epidemiology
and
toxicology
literature,
mechanistic
toxicity
and
general
topics.
The
product
of
the
workshop
will
be
a
report
that
summarizes
the
panelists'
and
observers'
comments,
conclusions,
and
recommendations
on
the
proposed
methodology.

II.
Background
A.
What
Action
is
the
Agency
Taking?

This
notice
constitutes
and
announces
the
closing
of
the
comment
periods
for
the
difenzoquat
and
diquat
dibromide
TREDs.
These
decisions
have
been
developed
as
part
of
the
public
participation
process
that
EPA
and
the
U.
S.
Department
of
Agriculture
(
USDA)
are
using
to
involve
the
public
in
the
reassessment
of
pesticide
tolerances
under
FFDCA.
EPA
must
review
tolerances
and
tolerance
exemptions
that
were
in
effect
when
FQPA
was
enacted
in
August
of
1996,
to
ensure
that
these
existing
pesticide
residue
limits
for
food
and
feed
commodities
meet
the
safety
standard
of
the
new
law.
In
reviewing
these
tolerances,
the
Agency
must
consider,
among
other
things,
aggregate
risks
from
nonoccupational
sources
of
pesticide
exposure,
where
there
increased
susceptibility
to
infants
and
children,
and
the
cumulative
effects
of
pesticides
with
a
common
mechanism
of
toxicity.
The
tolerances
are
considered
reassessed
once
the
safety
finding
has
been
made
that
the
aggregate
risks
are
not
of
concern.
A
reregistration
eligibility
decision
(
RED)
was
completed
for
difenzoquat
in
September
1994
and
for
diquat
dibromide
in
July
1995,
both
prior
to
FQPA
enactment,
and
therefore
needed
updated
assessments
to
consider
the
provisions
of
the
Act.
The
30
 
day
comment
periods
for
the
difenzoquat
and
diquat
dibromide
TREDs
were
closed
on
June
12,
2002
(
67
FR
40296)
(
FRL
 
7181
 
4).
As
neither
chemical
received
any
adverse
comments,
the
Agency
considers
the
TREDs
for
these
pesticides
as
immediate
final
decisions
and
hereby
closed.

B.
What
is
the
Agency's
Authority
for
Taking
this
Action?
The
legal
authority
for
this
decision
falls
under
FIFRA,
as
amended
in
1988
and
1996.
Section
4(
g)(
2)(
A)
of
FIFRA
directs
that,
after
submission
of
all
data
concerning
a
pesticide
active
ingredient,
``
the
Administrator
shall
determine
whether
pesticides
containing
such
active
ingredient
are
eligible
for
reregistration,''
and
either
reregister
products
or
take
other
``
appropriate
regulatory
action.''
