potential

of
quinoxyfen
in
an
aggregate
exposure
assessment.

E.
Safety
Determination
1.
U.
S.
population.
The
chronic
dietary
exposure
was
evaluated
using
a
chronic
reference
dose
(
RfD)
of
0.2
mg/
kg/
day
based
on
a
no
observed
adverse
effect
level
(
NOAEL)
of
20
mg/
kg/
day
from
chronic
rat,
chronic
dog,
and
rat
reproduction
studies
and
uncertainty
factor
of
100.
No
additional
Food
Quality
Protecction
Act
(
FQPA)
uncertainty
factor
is
needed.
For
the
U.
S.
general
population,
the
TMRC
was
estimated
to
be
0.000192
mg/
kg/
day.
Using
the
conservative
exposure
assumptions
described
in
Section
C.
and
based
on
the
completeness
and
reliability
of
the
toxicity
data,
the
aggregate
exposure
to
quinoxyfen
utilizes
0.1%
of
the
RfD
for
the
U.
S.
population.
EPA
generally
has
no
concern
for
exposures
below
100%
of
the
RfD
because
the
RfD
represents
the
level
at
or
below
which
daily
aggregate
dietary
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
Thus,
there
is
a
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
quinoxyfen
residues
from
the
proposed
uses.
2.
Infants
and
children.
FFDCA
section
408
provides
that
EPA
may
apply
an
additional
safety
factor
for
infants
and
children
in
the
case
of
threshold
effects
to
account
for
prenatal
and
postnatal
toxicity
and
the
completeness
of
the
data
base.
Based
on
the
current
toxicological
data
requirements,
the
data
base
for
quinoxyfen
relative
to
prenatal
and
postnatal
effects
for
children
is
complete.
In
assessing
the
potential
for
additional
sensitivity
of
infants
and
children
to
residues
of
quinoxyfen,
data
from
developmental
toxicity
studies
in
rats
and
rabbits
and
a
2­
generation
reproduction
study
in
the
rat
are
considered.
The
developmental
toxicity
studies
are
designed
to
evaluate
adverse
effects
on
the
developing
organism
resulting
from
pesticide
exposure
during
prenatal
development.
Reproduction
studies
provide
information
relating
to
effects
from
exposure
to
the
pesticide
on
the
reproductive
capability
and
potential
systemic
toxicity
of
mating
animals
and
on
various
parameters
associated
with
the
well­
being
of
offspring.
The
population
subgroup
with
the
highest
potential
exposure
are
children
(
1
 
6
yrs
old)
with
TMRC
of
0.00071
mg/
kg/
day.
Using
the
conservative
exposure
assumptions
previously
described
in
Section
C.
the
percent
RfD
utilized
by
the
potential
aggregate
exposure
to
quinoxyfen
residues
is
about
0.4%
for
children
(
1
 
6
yrs
old),
the
population
subgroup
with
highest
potential
exposure.
Quinoxyfen
had
no
effect
on
reproduction
or
embryo­
fetal
development
at
any
dosage
tested.
Therefore,
no
additional
FQPA
uncertainty
factor
is
needed.
Based
on
the
completeness
and
reliability
of
the
toxicity
data
and
the
conservative
exposure
assessment,
Dow
AgroSciences
concludes
that
there
is
a
reasonable
certainty
that
no
harm
will
result
to
infants
and
children
from
aggregate
exposure
to
quinoxyfen
residues
from
proposed
uses.
The
drinking
water
level
of
concern
(
DWLOC)
for
the
general
U.
S.
population
and
children
1
 
6
years
old
(
population
subgroup
with
the
highest
potential
exposure)
was
calculated
to
be
6,993
µ
g/
L
and
1,993
µ
g/
L,
respectively.
The
DWLOCs
are
substantially
greater
than
the
estimated
residue
concentration
in
ground
water
or
surface
water;
therefore,
exposure
to
quinoxyfen
would
not
result
in
unacceptable
levels
of
aggregate
human
health
risk.

F.
International
Tolerances
There
are
no

maximum
residue
levels
established
for
residues
of
quinoxyfen
on
grapes,
hops,
and
cherries.

Background
Information
Diazinon
is
an
organophosphorous
insecticide
and
is
one
of
the
most
widely
used
insecticides
in
the
U.
S.
It
is
used
for
outdoor
non­
agricultural,
as
well
as
agricultural,
pest
control.
Under
a
December
5,
2000
Memorandum
of
Agreement
(
MOA)
between
Syngenta
Crop
Protection,
Inc.
and
EPA,
Syngenta
requested,
under
FIFRA
section
6(
f),
that
EPA
cancel,
effective
as
of
June
30,
2003,
the
registrations
of
all
of
Syngenta's
diazinon
manufacturing­
use
products
which
are
used
in
formulation
for
outdoor
non­
agricultural
use.
In
the
MOA,
EPA
expressed
that
it
would
not
contemplate
permitting
sale,
distribution
or
use
of
existing
stocks
of
these
outdoor
non­
agricultural
manufacturing­
use
products,
except
for
return
to
the
registrant
for
purposes
of
relabeling
for
export,
or
disposal.
In
a
letter
dated
April
8,
2003,
Syngenta
Crop
Protection,
Inc.
requested
a
voluntary
cancellation
of
all
its
remaining
registrations
(
agricultural
uses)
for
products
containing
diazinon,
to
be
effective
June
30,
2003.
Syngenta's
April
8
request
is
contingent
upon
EPA's
granting
of
certain
existing
stocks
provisions,
which
are
set
forth
in
Unit
IV.
of
this
Notice.
EPA
intends
to
grant
Syngenta's
requests
by
issuing
a
cancellation
order
at
the
close
of

Diazinon
belongs
to
a
group
of
pesticides
known
as
organophosphates
(

EPA
has

an

B.
Requests
for
Voluntary
Cancellation
Under
section
6(
f)(
1)(
A)
of
FIFRA,
registrants
may
request,
at
any
time,
that
their
pesticide
registrations
be
canceled
or
amended
to
terminate
one
or
more
pesticide
uses.
Section
6(
f)(
1)(
B)
of
FIFRA
requires
that
before
acting
on
a
request
for
voluntary
cancellation,
EPA
must
provide
a
30
 
day
public
comment
period
on
the
request
for
voluntary
cancellation.
In
addition,
section
6(
f)(
1)(
C)
of
FIFRA
requires
that
EPA
provide
a
180
 
day
comment
period
on
a
request
for
voluntary
termination
of
any
minor
agricultural
use
before
granting
the
request,
unless:
(
1)
The
registrants
request
a
waiver
of
the
comment
period,
or
(
2)
the
Administrator
determines
that
continued
use
of
the
pesticide
would
pose
an
unreasonable
adverse
effect
on
the
environment.
Syngenta
requested
a
waiver
of
the
180
 
day
comment
period.
The
Agency
will
therefore
apply
a
30
 
day
comment
period.
Unless
the
Agency
determines
that
there
are
substantive
comments
that
warrant
further
review
of
this
request,
an
order
will
be
issued
canceling
all
of
these
registrations.

What
is
the
Agency's
Authority
for
Taking
this
Action?

Section
6(
f)(
1)
of
FIFRA
provides
that
a
registrant
of
a
pesticide
product
may
at
any
time
request
that
any
of
its
pesticide
registrations
be
canceled.
FIFRA
further
provides
that,
before
acting
on
the
request,
EPA
must
publish
a
notice
of
receipt
of
any
such
request
in
the
Federal
Register.
Thereafter,
the
Administrator
may
approve
such
a
request.
IV.
Provisions
for
Disposition
of
Existing
Stocks
The
Agency
intends
to
issue
a
cancellation
order
following
consideration
of
all
comments
received
during
the
comment
period,
unless
the
comments
warrant
further
review
of
this
request.
Any
cancellation
order
issued
in
response
to
this
request
will
have
an
expected
effective
date
of
June
30,
2003.
Existing
stocks
are
those
stocks
of
registered
pesticide
products
which
are
currently
in
the
United
States
and
which
have
been
packaged,
labeled,
and
released
for
shipment
prior
to
the
effective
date
of
the
cancellation
action.
EPA
intends
to
include
the
following
existing
stocks
provisions
in
the
cancellation
order
issued
pursuant
to
Syngenta's
cancellation
requests
described
in
this
Notice.
