Chlorpropham
will
be
reevaluated
at
that
time
and
additional
studies
may
be
required.
Additionally,
the
Agency
has
evaluated
the
dietary
risk
associated
with
chlorpropham
and
has
determined
that
provided
the
Special
Local
Need
(
SLN)

Easter
lily

use
is
amended
to
reduce
the
maximum
rate
of
application
from
3.99
pounds
active
ingredient/
acre
to
2.0
pounds
active
ingredient/
acre,
as
agreed
upon
by
stakeholders,
there
is
a
reasonable
certainty
that
no
harm
to
any
population
subgroup
will
result
from
aggregate
exposure
to
chlorpropham
when
considering
dietary
exposure
and
all
other
non­
occupational
sources
of
pesticide
exposure
for
which
there
is
reliable
information.
Therefore,
with
this
mitigation
measure
in
place,
15
tolerances
are
now
considered
reassessed
and
9
new
tolerances
will
be
established
for
residues
of
chlorpropham
in/
on
raw
agricultural
commodities
under
section
408(

of
the
FFDCA.
All
registrants
of
pesticide
products
containing
the
active

listed

this

have
been
sent
the
appropriate
TRED

and
must
respond

The

is
being
conducted
under
Congressionallymandated

and
EPA
recognizes
both
the
need

``
the

either
reregistering

taking
``
other
appropriate

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

In
1995,
the
Agency
published
its
Reregistration
Eligibility
Decision
(
RED)
for
diquat
dibromide.
Subsequent
to
the
publication
of
the
1995
RED,
the
technical
registrant
submitted
additional
data
to
further
refine
diquat
dibromide
worker
exposure
and
residential
broadcast
spray
use
scenarios.
Changes
to
the
PPE
label
requirements
of
the
1995
RED
are
based
on
the
submission
of
additional
data
from
a
biomonitoring
study
of
knapsack
applications
of
the
closely
related
chemical
paraquat,
and
a
reconsideration
of
the
acute
dermal
toxicity
endpoint.
The
Agency
reevaluated
the
dermal
toxicity
endpoint
and
rendered
a
decision
that
the
repeated
dose
dermal
toxicity
study
used
for
the
1995
RED
was
not
appropriate
for
use
in
the
risk
assessment
because
the
skins
of
the
rats
used
in
the
study
were
compromised.
Instead,
the
Agency
extrapolated
a
dermal
toxicity
endpoint
from
a
shortterm
oral
study
on
rabbits.
The
Agency
has
also
reevaluated
dermal
absorption
assumptions.
Previously,
EPA
assumed
a
standard
absorption
rate
of
4.1%,
based
on
a
rat
dermal
absorption
study.
Syngenta
cited
a
human
dermal
absorption
study
estimating
a
0.3%
dermal
absorption
rate
for
diquat
dibromide
(
Feldman
RJ
and
Maibach
HI,
``
Percutaneous
penetration
of
some
pesticides
and
herbicides
in
man''
Tox.
Appl.
Pharm.
28
126
 
132,
1974).
The
Agency
has
relied
on
data
provided
by
the
Feldman­
Maibach
study
for
previous
risk
assessments,
and
believes
the
study
to
be
acceptable
and
the
data
valid
for
use
in
this
risk
assessment.
The
use
of
the
dermal
absorption
factor
of
0.3%
further
refines
all
aggregate
margins
of
exposure
(
MOEs)
above
the
target
MOE
of
100,
which
would
not
be
of
concern
to
the
Agency.
The
Agency
has
evaluated
the
request
to
modify
the
cited
label
requirements
and
summarized
its
assessment
in
the
Occupational
Risk
Evaluation:
``
Assessing
Syngenta's
Request
to
Modify
Diquat
Dibromide
Label
Requirements,''
dated
February
14,
2002.
In
addition,
the
``
HED
Risk
Assessment
for
Tolerance
Reassessment
Eligibility
Document
(
TRED),''
March
6,
2002,
and
the

Data,''
March
13,
2002,
were
used
to
aid
in
the
assessment
of
aggregate
risks
from
residential
uses.
Any
labeling
changes
are
presented
in
the
``

Table,''
which
summarizes
the
labeling
requirements
for
this
action.

In
summary,
the
Agency
expects
to
change
the
label
requirements
of
the
1995
RED
for
worker
PPE
and
residential
broadcast
spray
uses.
