Dear
Registrant:

This
is
to
inform
you
that
the
Environmental
Protection
Agency
(
hereafter
referred
to
as
EPA
or
the
Agency)
has
completed
its
review
of
the
available
data
and
public
comments
received
related
to
the
preliminary
risk
assessment
for
the
miticide
propargite.
The
Agency
has
revised
the
human
health
and
environmental
effects
risk
assessments
based
on
the
comments
received
during
the
public
comment
period
and
additional
data
received
from
the
registrant.
Based
on
the
EPA's
revised
risk
assessments
for
propargite,
EPA
has
identified
risk
mitigation
measures
that
the
Agency
believes
are
necessary
to
address
the
human
health
and
environmental
risks
associated
with
the
current
use
of
propargite.
EPA
is
now
publishing
its
reregistration
eligibility,
risk
management,
and
tolerance
reassessment
decisions
for
the
current
uses
of
propargite,
and
its
associated
human
health
and
environmental
risks.
The
Agency's
decision
on
the
individual
chemical
propargite
can
be
found
in
the
attached
document
entitled,
"
Reregistration
Eligibility
Decision
for
Propargite"
which
was
approved
on
September
28,
2001.

A
Notice
of
Availability
for
the
Reregistration
Eligibility
Decision
for
Propargite
is
being
published
in
the
Federal
Register.

As
part
of
the
Agency's
effort
to
involve
the
public
in
the
implementation
of
the
Food
Quality
Protection
Act
of
1996
(
FQPA),
the
Agency
is
undertaking
a
special
effort
to
maintain
open
public
dockets
and
to
engage
the
public
in
the
reregistration
and
tolerance
reassessment
processes.
In
cooperation
with
the
U.
S.
Department
of
Agriculture,
the
Agency
held
a
teleconference
on
July
19,
2000,
during
which
the
results
of
the
human
health
and
environmental
effects
risk
assessments
were
presented
to
interested
stakeholders.
Information
discussed
during
the
call,
such
as
propargite
usage
and
occupational
practices,
are
reflected
in
this
RED.
Also,
a
close­
out
conference
call
was
conducted
on
September
25,
2001
with
many
of
the
same
participants
from
the
July
19
conference
call,
to
discuss
the
risk
management
decisions
and
resultant
changes
to
the
propargite
labels.
4
A
risk
mitigation
proposal
for
propargite
was
submitted
by
Uniroyal
Chemical,
the
technical
registrant.
During
the
public
comment
period
provided
for
the
preliminary
risk
assessment,
EPA
also
received
comments
from
the
Almond
Hullers
and
Processors
Association
and
the
National
Agricultural
Aviation
Association
(
NAAA).
Subsequent
to
the
comment
period
for
the
propargite
preliminary
risk
assessment,
EPA
also
received
a
series
of
letters
and
e­
mails
from
several
growers
groups
and
extension
services
attesting
to
the
benefits
of
propargite.
These
comments
can
also
be
found
in
the
public
docket
for
propargite.

Please
note
that
the
propargite
risk
assessment
and
the
attached
RED
concern
only
this
particular
pesticide.
The
Food
Quality
Protection
Act
(
FQPA)
requires
that,
when
considering
whether
to
establish,
modify,
or
revoke
a
tolerance,
the
Agency
consider
"
available
information"
concerning
the
cumulative
effects
of
a
particular
pesticide's
residues
and
"
other
substances
that
have
a
common
mechanism
of
toxicity."
At
this
time,
the
Agency
does
not
believe
that
propargite
shares
a
common
mechanism
of
toxicity
with
other
pesticides.
Therefore,
propargite
is
not
subject
to
any
cumulative
risk
assessment
as
required
by
the
Food
Quality
Protection
Act
(
FQPA).

This

specific
Data
Call­
In(
s)

DCI)
that
outline(
s)
further
data
requirements
for
this
chemical.
Note
that
registrants
of
propargite
must
respond
to
DCIs
issued
by
the
Agency
within
90
days
of
receipt
of
this
letter.
This
RED
also
contains
labeling
requirements
for
propargite
products.
End­
use
product
labels
must
be
revised
by
the
manufacturer
to
adopt
the
changes
set
forth
in
Section
IV
of
this
document.
Instructions
for
registrants
on
submitting
revised
labeling
and
the
time
frame
established
to
do
so
can
be
found
in
Section
V
of
this
document.

Should
a
registrant
fail
to
implement
any
of
the
risk
mitigation
measures
outlined
in
this
document,
the
Agency
will
continue
to
have
concerns
about
the
risks
posed
by
propargite.
Where
the
Agency
has
identified
any
unreasonable
adverse
effect
to
human
health
and
the
environment,
the
Agency
may
at
any
time
initiate
appropriate
regulatory
action
to
address
this
concern.
At
that
time,
any
affected
person(
s)
may
challenge
the
Agency's
action.

There
will
be
a
60­
day
public
comment
period
for
this
document,
commencing
on
the
day
the
Notice
of
Availability
publishes
in
the

Executive
Summary
EPA
has
completed
its
review
of
public
comments
on
the
preliminary
risk
assessments
and
is
issuing
its
risk
management
decision
for
propargite.
The
revised
risk
assessments
are
based
on
review
of
the
required
target
data
base
supporting
the
use
patterns
of
currently
registered
products
and
additional
information
received.
The
Agency
invited
stakeholders
to
provide
proposals,
ideas
or
suggestions
on
appropriate
mitigation
measures
before
the
Agency
issued
its
risk
mitigation
decision
on
propargite.
After
considering
the
risks
identified
in
the
revised
risk
assessment,
mitigation
measures
proposed
by
Uniroyal
Chemical
Company,
the
technical
registrant
of
propargite,
and
comments
and
mitigation
suggestions
from
other
interested
parties,
EPA
developed
its
risk
management
decision
for
uses
of
propargite
that
pose
risks
of
concern.
This
decision
is
discussed
fully
in
this
document.

Propargite
is
an
organosulfur
miticide/
acaricide
used
on
a
variety
of
bearing
and
non­
bearing
agricultural
food
crops,
as
well
as
non­
food
agricultural
sites.
It
was
first
registered
in
1969.
Approximately
2
million
pounds
of
propargite
active
ingredient
are
applied
annually.
Sites
on
which
propargite
has
the
highest
percent
of
crop
treated
include
grapes,
walnuts,
almonds,
nectarines,
and
mint.

The
Food
Quality
Protection
Act
(
FQPA)
requires
that,
when
considering
whether
to
establish,
modify,
or
revoke
a
tolerance,
the
Agency
consider
"
available
information"
concerning
the
cumulative
effects
of
a
particular
pesticide's
residues
and
"
other
substances
that
have
a
common
mechanism
of
toxicity."
The
Agency
does
not
believe
that
propargite
shares
a
common
mechanism
of
toxicity
with
other
chemicals.
Although
chemical
class
is
not
necessarily
synonymous
with
a
common
mechanism
of
toxicity,
structurally
similar
chemical
substances
do
frequently
exhibit
common
modes
of
toxicity
and
may
be
considered
together
by
EPA
for
purposes
of
cumulative
risk
assessment.
Propargite
is
the
only
organosulfur
chemical
that
is
subject
to
reregistration
under
FIFRA
and
tolerance
reassessment
under
the
FQPA.
Therefore,
propargite
is
not
subject
to
any
cumulative
risk
assessment
as
required
by
the
Food
Quality
Protection
Act
(
FQPA).

Overall
Risk
Summary
EPA's
human
health
risk
assessment
for
propargite
indicates
that
food
risk,
both
acute
and
chronic,
are
not
a
concern
(
2%
of
aPAD
and
<
1%
of
cPAD).
The
drinking
water
risk
estimates
for
acute
and
chronic
exposures,
based
on
screening
models
and
USGS
monitoring
data,
are
also
not
of
concern
for
either
ground
or
surface
waters.
Propargite
is
classified
as
a
B2
chemical
carcinogen
based
on
the
appearance
of
intestinal
tumors
in
test
animals.
The
cancer
dietary
risk
from
food
alone
is
1.8
x
10
­
7
for
the
general
U.
S.
population,
and
is
not
a
concern
for
the
Agency.
However,
the
cancer
drinking
water
risk
from
surface
water
alone
may
be
of
concern,
based
on
the
screening
models
and
USGS/
NAWQA
monitoring
data.
There
are
also
concerns
for
workers
who
mix,
load,
and
apply
propargite
to
agricultural
sites.
Finally,
EPA
has
identified
a
chronic
reproductive
risk
of
concern
to
birds
and
mammals,
and
some
risk
to
aquatic
species.

To
mitigate
risks
of
concern
posed
by
the
uses
of
propargite,
EPA
considered
the
mitigation
15
proposal
submitted
by
the
technical
registrant,
as
well
as
comments
and
mitigation
ideas
from
other
interested
parties,
and
has
decided
on
a
number
of
label
amendments
to
address
the
worker,
and
ecological
concerns.
Results
of
the
risk
assessments,
and
required
label
amendments
to
mitigate
those
risks,
are
presented
in
this
RED.

Dietary
Risk
 
Food
EPA's
dietary
risk
analysis
consists
of
three
parts:
acute
dietary
risk,
chronic
(
non­
cancer)
dietary
risk,
and
chronic
cancer
risk.
The
acute
dietary
exposure
analysis
was
performed
using
a
refined
Tier
3
approach
based
on
the
Dietary
Exposure
Evaluation
Model
(
DEEM
 
)
.
The
DEEM
 
analysis
evaluated
the
individual
food
consumption
as
reported
by
respondents
in
the
USDA
1989­
91
Continuing
Surveys
for
Food
Intake
by
Individuals
(
CSFII)
and
accumulated
exposure
to
the
chemical
for
each
commodity.
Under
this
analysis,
a
risk
estimate
that
is
less
than
100%
of
the
acute
Population
Adjusted
Dose
("
aPAD")
(
the
dose
at
which
an
individual
could
be
exposed
on
any
given
day
and
no
adverse
health
effects
would
be
expected)
does
not
exceed
the
Agency's
level
of
concern.
Based
on
the
estimates
for
acute
exposure
to
propargite,
the
percentage
of
aPAD
utilized
is
2
percent;
therefore
the
acute
dietary
(
food)
risk
estimate
for
propargite
is
not
of
concern.

For
the
chronic
(
non­
cancer)
dietary
risk
assessment,
an
average
of
consumption
values
for
each
sub­
population
is
combined
with
average
residue
values
in/
on
commodities
over
a
70­
year
lifetime
to
determine
average
exposure.
A
risk
estimate
that
is
less
than
100%
of
the
chronic
PAD
(
the
dose
at
which
an
individual
could
be
exposed
over
the
course
of
a
lifetime
and
no
adverse
health
effects
would
be
expected)
does
not
exceed
the
Agency's
level
of
concern.

The
chronic
dietary
analysis
utilized
USDA
Pesticide
Data
Program
(
PDP)
monitoring
data,
field
trial
data,
calculated
livestock
anticipated
residues,
and
percent
crop
treated
information.
Based
on
that
analysis,
the
percentage
of
cPAD
utilized
is
expected
to
be
less
than
1
percent
for
the
U.
S.
population
and
all
subpopulations.
Therefore,
the
chronic
dietary
(
food)
risk
estimate
is
also
not
of
concern.

Chronic
(
cancer)
dietary
risk
is
also
calculated
by
using
the
average
consumption
values
for
food
and
average
residue
values
for
those
foods
over
a
70­
year
lifetime.
The
chronic
exposure
value
is
combined
with
a
linear
low­
dose
risk
model
("
Q
1
*")
to
determine
the
lifetime
(
cancer)
risk
estimate.
The
Agency
generally
considers
risks
greater
than
1
x
10­
6
(
1
in
1
million)
to
exceed
its
level
of
concern
for
cancer
dietary
exposure.
Propargite
is
classified
as
a
B2
chemical
carcinogen
(
likely
human
carcinogen),
based
on
the
appearance
of
intestinal
tumors
in
rats.
The
results
of
the
Q
1
*
model
indicate
that
the
cancer
dietary
risk
from
food
alone
is
1.8
x
10­
7
for
the
general
U.
S.
population.
Therefore,
the
cancer
dietary
risk
from
food
alone
is
not
a
concern.

Dietary
Risk
 
Drinking
Water
Drinking
water
exposure
to
pesticides
can
occur
through
groundwater
and
surface
water
contamination.
EPA
considers
acute
(
one
day)
and
chronic
(
lifetime)
drinking
water
risks
and
uses
either
modeling
or
actual
monitoring
data,
if
available,
to
estimate
those
risks.
To
determine
the
16
maximum
allowable
contribution
from
water
allowed
in
the
diet,
EPA
first
looks
at
how
much
of
the
overall
allowable
risk
is
contributed
by
food
and
then
determines
a
"
drinking
water
level
of
comparison"
(
DWLOC)
to
determine
whether
modeled
or
monitoring
estimated
environmental
concentration
(
EEC)
levels
exceed
this
level.
EECs
that
are
above
the
corresponding
DWLOC
exceed
the
Agency's
level
of
concern.
Modeling
is
generally
considered
to
be
an
unrefined
assessment
and
provides
high­
end
estimates.

Based
on
modeling
data,
the
acute
drinking
water
exposures
for
females
13­
50
years
old
for
surface
water
and
groundwater
were
less
than
the
acute
DWLOC
of
2400
ppb.
Since
the
EEC
of
34
ppb
for
surface
water
and
0.006
for
groundwater
is
less
than
the
DWLOC,
the
acute
dietary
risk
from
food
and
drinking
water
are
not
a
concern.
Similarly,
modeling
data
for
chronic
drinking
water
concentrations
for
surface
water
and
groundwater
exposures
also
indicated
that
chronic
dietary
risk
from
food
and
drinking
water
are
not
of
concern.
The
DWLOCs
were
1400
ppb
for
the
U.
S.
population
and
400
ppb
for
infants
and
children
compared
to
a
chronic
EEC
of
8.7
for
surface
water
and
0.006
for
groundwater.
However,
modeling
data
does
indicate
a
concern
for
cancer.
The
EECs
for
surface
water
of
4.8
ppb
exceed
the
cancer
DWLOC
of
0.71
ppb.

Although
the
cancer
drinking
water
risk
estimates
from
surface
water
is
above
the
Agency's
level
of
concern,
the
Agency
believes
the
modeling
estimates
and
monitoring
data
upon
which
the
assessment
is
based
are
conservative.
Actual
drinking
water
exposure
to
propargite
from
surface
water
sources
is
expected
to
be
less.
Moreover,
the
registrant
has
agreed
to
add
label
statements
prohibiting
application
of
propargite
by
ground
within
50
feet
or
by
air
within
75
feet
of
aquatic
areas
to
mitigate
the
drinking
water
(
and
ecological)
risk
concerns.
The
registrant
has
also
agreed
to
conduct
a
drinking
water
monitoring
study
to
confirm
the
Agency's
belief
that
drinking
water
exposures
will
not
exceed
the
level
of
concern.

Residential
Risk
Use
of
propargite
in
residential
settings
is
not
permitted.
Therefore,
the
Agency
does
not
expect
residential
exposures
to
propargite.

Aggregate
Risk
An
aggregate
risk
assessment
looks
at
the
combined
risk
from
dietary
exposure
(
food
and
drinking
water
routes)
as
well
as
exposures
from
non­
occupational
sources
(
e.
g.,
residential
uses).
Generally,
all
risks
from
these
exposures
must
have
MOEs
of
greater
than
100
to
be
not
of
concern
to
the
Agency.
Because
there
are
no
residential
uses
of
propargite,
the
aggregate
risks
are
limited
to
dietary
(
food
and
water)
exposure.
The
risks
from
those
combined
exposures
are
discussed
above
in
the
preceding
"
Dietary
Risk
­
Drinking
Water"
section.

Occupational
Risk
Occupational
exposure
to
propargite
is
of
concern
to
the
Agency,
and
it
has
been
determined
17
that
a
number
of
mitigation
measures
are
required.
For
the
agricultural
uses
of
propargite,
several
mixer/
loader/
applicator
risk
scenarios
currently
exceed
the
Agency's
level
of
concern
(
i.
e.,
dermal
MOEs
are
less
than
100)
at
baseline
level
of
protection
(
shoes,
socks,
long­
sleeved
shirts
and
long
pants,
and
no
gloves)
for
acute
and
chronic
health
effects.
Also,
mixer
and
loader
cancer
risks,
when
calculated
without
personal
protective
equipment
or
engineering
controls,
can
range
up
to
1
x
10­
3.
That
estimate
also
exceeds
the
Agency's
level
of
concern.
EPA
believes
these
risks
can
be
mitigated
to
an
acceptable
level
with
the
following
label
restrictions:
(
1)
requiring
use
of
personal
protective
equipment
for
certain
scenarios;
(
2)
requiring
engineering
controls
for
certain
scenarios;
(
3)
increasing
restricted
entry
intervals
for
certain
uses,
and
(
4)
reclassifying
propargite
as
a
restricted
use
pesticide.

Ecological
Risk
Ecological
risks
are
of
concern
to
the
Agency.
Based
on
toxicity
studies
submitted
by
the
Registrant,
propargite
poses
a
potential
for
adverse
effects
on
reproduction
in
birds
and
mammals.
Risk
to
aquatic
organisms
and
plants
is
generally
lower
than
the
risk
for
birds
and
mammals;
however,
the
chronic
risk
concern
levels
for
freshwater
invertebrates
and
freshwater
fish
are
either
approached
or
exceeded
for
over
60
days
from
multiple
propargite
applications.
Propargite
is
also
expected
to
be
highly
toxic
to
amphibians.
To
address
these
ecological
risks,
the
registrant
has
agreed
to:

°
Decrease
seasonal
maximum
rates
for
several
high
use
crops.
See
Table
11.
°
Add
spray
intervals
of
21
days
for
most
food
crops
(
28
days
for
citrus).
See
Table
12.
°
Decrease
the
number
of
annual
applications
for
cotton.
°
Add
label
statements
prohibiting
application
of
propargite
by
ground
within
50
feet
or
by
air
within
75
feet
of
aquatic
areas.
°

Conclusions
The
Agency
is
issuing
this
Reregistration
Eligibility
Document
(
RED)
for
Propargite,
as
announced
in
a
Notice
of
Availability
published
in
the
Federal
Register.
This
RED
document
includes
guidance
and
time
frames
for
complying
with
any
required
label
changes
for
products
containing
propargite.
With
the
addition
of
the
label
restrictions
and
amendments
detailed
in
this
document,
the
Agency
has
determined
that
all
currently
registered
uses
of
propargite
are
eligible
for
reregistration.

There
is
a
60­
day
public
comment
period
for
this

Introduction
The
Federal
Insecticide,
Fungicide,
and
Rodenticide
Act
(
FIFRA)
was
amended
in
1988
to
accelerate
the
reregistration
of
products
with
active
ingredients
registered
prior
to
November
1,
1984.
The
amended
Act
calls
for
the
development
and
submission
of
data
to
support
the
reregistration
of
an
active
ingredient,
as
well
as
a
review
of
all
submitted
data
by
the
U.
S.
Environmental
Protection
Agency
(
referred
to
as
EPA
or
"
the
Agency").
Reregistration
involves
a
thorough
review
of
the
scientific
database
underlying
a
pesticide's
registration.
The
purpose
of
the
Agency's
review
is
to
reassess
the
potential
hazards
arising
from
the
currently
registered
uses
of
the
pesticide;
to
determine
the
need
for
additional
data
on
health
and
environmental
effects;
and
to
determine
whether
the
pesticide
meets
the
"
no
unreasonable
adverse
effects"
criteria
of
FIFRA.

On
August
3,
1996,
the
Food
Quality
Protection
Act
of
1996
(
FQPA)
was
signed
into
law.
This
Act
amends
FIFRA
to
require
tolerance
reassessment
during
reregistration.
It
also
requires
that
by
2006,
EPA
must
review
all
tolerances
in
effect
on
the
day
before
the
date
of
the
enactment
of
the
FQPA,
which
was
August
3,
1996.
FQPA
also
amends
the
FFDCA
to
require
a
safety
finding
in
tolerance
reassessment
based
on
factors
including
an
assessment
of
cumulative
effects
of
chemicals
with
a
common
mechanism
of
toxicity.
Propargite
is
an
organosulfur
chemical,
and
is
the
only
chemical
in
this
class
that
is
subject
to
tolerance
assessment
under
FQPA.
Although
chemical
class
is
not
necessarily
equivalent
to
a
common
mechanism
of
action,
in
some
cases,
chemicals
within
the
same
class
have
been
shown
to
share
a
common
mechanism
of
action
and
are
being
considered
together
for
purposes
of
a
cumulative
assessment
(
e.
g.,
the
organophosphates).
For
propargite,
there
are
no
other
organosulfur
chemicals
being
reviewed
under
FQPA,
and
the
Agency
does
not
believe
that
propargite
shares
a
common
mechanism
of
toxicity
with
other
chemicals.
Therefore,
propargite
is
not
subject
to
any
cumulative
risk
assessment
as
required
by
the
FQPA.

This
document
presents
the
Agency's
revised
human
health
and
ecological
risk
assessments;
the
tolerance
reassessment;
and
the
reregistration
eligibility
decision
for
propargite.

The
implementation
of
FQPA
has
required
the
Agency
to
revisit
some
of
its
existing
policies
relating
to
the
determination
and
regulation
of
dietary
risk,
and
has
also
raised
a
number
of
new
issues
for
which
policies
need
to
be
created.
These
issues
were
refined
and
developed
through
collaboration
between
the
Agency
and
the
Tolerance
Reassessment
Advisory
Committee
(
TRAC),
which
was
composed
of
representatives
from
industry,
environmental
groups,
and
other
interested
parties.
The
TRAC
identified
the
following
science
policy
issues
it
believed
were
key
to
the
implementation
of
FQPA
and
tolerance
reassessment:

C
Applying
the
FQPA
10­
fold
safety
factor
C
Whether
and
how
to
use
probabilistic
analyses
in
dietary
exposure
assessments
C
How
to

assessments
C

C
How
to
conduct
a

assessment
for
organophosphate
or
other
pesticides
with
a
common
mechanism
of
toxicity
C
Selection
of
appropriate
toxicity
endpoints
for
risk
assessments
of
organophosphates
C
Whether
and
how
to
use
data
derived
from
human
studies
The
process
developed
by
the
TRAC
calls
for
EPA
to
provide
one
or
more
documents
for
public
comment
on
each
of
the
policy
issues
described
above.
Each
of
these
issues
is
evolving
and
in
a
different
stage
of
refinement.
Some
issue
papers
have
already
been
published
for
comment
in
the
Federal
Register
and
others
will
be
published
shortly.

This
document
consists
of
six
sections.
Section
I
contains
the
regulatory
framework
for
reregistration/
tolerance
reassessment
.
Section
II
provides
a
profile
of
the
use
and
usage
of
the
chemical.
Section
III
gives
an
overview
of
the
revised
human
health
and
environmental
effects
risk
assessments
resulting
from
public
comments
and
other
information.
Section
IV
presents
the
Agency's

II.
Chemical
Overview
A.
Regulatory
History
Propargite
was
first
registered
in
the
United
States
in
1969
for
control
of
mites
on
a
variety
of
field,
fruit,
and
vegetable
crops,
as
well
as
ornamentals.
It
is
manufactured
by
Uniroyal
Chemical,
the
sole
propargite
registrant,
under
the
trade
names
Omite
and
Comite.
EPA
issued
a
Registration
Standard
for
Propargite
on
September
30,
1986
(
PB
87­
139358).
A
data
call­
in
was
issued
on
October
13,
1995.
In
April
5,
1996,
the
Agency
and
the
registrant
signed
an
agreement
under
which
the
registrant
voluntarily
canceled
certain
uses
of
the
pesticide.
The
uses
canceled
under
the
agreement
included
those
for
apricots,
apples,
peaches,
pears,
plums,
figs,
cranberries,
strawberries,
green
beans,
and
lima
beans.
Based
on
Agency
analysis
of
submitted
residue
monitoring
data,
those
uses
were
believed
to
pose
an
unacceptable
carcinogenicity
dietary
risk.
Tolerances
for
these
10
uses
were
subsequently
revoked
(
64
FR
39068;
July
21,
1999).

In
an
effort
to
promote
transparency
of
the
reregistration
process
and
public
understanding
of
regulatory
decisions,
the
Agency,
in
cooperation
with
the
U.
S.
Department
of
Agriculture
(
USDA)
modified
the
reregistration
and
tolerance
reassessment
process
in
1998.
This
modified
process
provides
opportunities
for
stakeholders
to
ask
questions
about
and
provide
input
to
the
risk
assessment
and
risk
mitigation
strategies,
via
conference
calls
and
other
formats.
Consistent
with
this
process,
a
conference
call
was
conducted
on
July
19,
2000
with
EPA,
USDA,
the
registrant,
and
other
stakeholders
(
i.
e.,
growers,
commodity
groups,
and
others)
to
discuss
the
basis
of
the
calculated
risks
of
propargite,
and
the
Agency's
resultant
risk
concerns.
Information
discussed
during
the
call,
such
as
propargite
usage
and
occupational
practices,
are
reflected
in
this
RED.

with
many
of
the
same
participants
from
the
July

2000
conference
call,
to
discuss
the
risk
management
decisions
and
resultant
changes
to
the
propargite
labels.

This
RED
was
signed
on
September
28,
2001.
A
post­
signature
comment
period
opened
April
18,
2002
and
closed
June
17,
2002.
The
Environmental
Protection
Agency
has
reviewed
and
responded
to
the
public
comments.
As
a
result
of
its
review
of
the
public
comments,
the
Agency
revised
this
Propargite
RED,
where
appropriate.
The
comments
and
the
Agency's
responses
are
available
for

for
propargite
were
made
available
in
the
public
docket
and
on
the
internet
on
August
2,
2000.
The
Agency
reviewed
and
addressed
all
comments
on
the
risk
assessment
documents.
There
is
a
discussion
of
these
comments
in
Section
IV,
later
in
this
document.

A.
Human
Health
Risk
Assessment
In
response
to
comments
and
studies
submitted,
the
risk
assessments
were
updated
and
refined.
The
conclusions
of
the
risk
assessment
are
summarized
below.

Dietary
Risk
from
Food
a.
Toxicity
The
Agency
has
reviewed
all
toxicity
studies
submitted
and
has
determined
that
the
toxicity
database
is
sufficiently
complete,
and
that
it
supports
a
reregistration
eligibility
determination
for
all
currently
registered
uses.

Propargite
is
classified
as
a
B2
chemical
carcinogen
based
on
the
appearance
of
intestinal
tumors
in
test
animals.
The
cancer
concern
was
based
on
a
2­
year
cancer
bioassay
conducted
on
Sprague
Dawley
("
SD")
rats.
In
that
study,
propargite
caused
fatal
tumors
of
the
intestine
in
both
male
and
female
rats.
In
other
studies
on
mice
and
Wistar
rats,
propargite
did
not
exhibit
carcinogenicity
or
mutagenicity.
In
the
SD
rat
study,
there
was
a
greater
response
in
males
and
therefore,
intestinal
tumors
in
male
rats
were
selected
for
dose­
response
modeling.
Statistical
analysis
conducted
on
the
survival
data
indicated
that
there
was
a
dose­
related
increase
in
mortality.
The
usual
Agency
practice
in
such
instances
is
to
use
the
Weibull
time­
to­
tumor
model
which
takes
into
account
both
time
and
dose
in
estimating
probability
of
tumor
occurrence
to
calculate
the
cancer
risk
in
humans.
After
discussions
with
the
Registrant
and
Agency
experts
on
alternative
approaches
to
statistical
cancer
modeling,
the
Agency
concluded
that
it's
initial
analysis,
based
on
the
time­
to­
tumor
model,
had
not
correctly
accounted
for
the
survival
data
and
that
the
simpler
Quantal
model,
which
estimates
tumor
incidence
only
as
a
function
of
dose,
should
be
used
instead.

A
time­
to­
tumor
model
is
appropriate
when
there
is
dose­
related
mortality
in
test
animals
from
26
non­
cancer
toxicity.
When
such
dose­
related
responses
occur,
animals
dying
early
from
non­
cancer
causes
would
presumably
not
be
at
risk
for
developing
a
tumor.
In
the
present
case,
however,
the
Agency
realized
that
the
early
deaths
occurring
in
the
study
were
explained
by
animals
dying
from
the
intestinal
tumors
before
the
end
of
the
study,
and
therefore,
those
animals
were
clearly
at
risk
for
developing
tumors.
Thus,
the
more
complex
time­
to­
tumor
model
was
not
appropriate.
Additionally,
further
statistical
analysis
performed
by
the
registrant
clearly
demonstrated
that
the
Quantal
model
fit
the
data
from
the
study
very
well,
while
the
fit
of
the
time­
to­
tumor
was
poor.
The
net
effect
of
the
use
of
the
Quantal
Model
for
propargite
is
that
the
estimated
cancer
potency
of
propargite
is
approximately
6
times
lower
than
that
presented
in
the
preliminary
risk
assessment
of
June
6,
2000.

Further
details
on
the
toxicity
of
propargite
can
be
found
in
the
September
13,
2001
Human
Health
Risk
Assessment,
and
the
August
14,
2001
Memorandum
"
Recommendation
for
Selection
of
Cancer
Dose­
Response
Model
and
Q
1
*
for
Propargite".
A
brief
overview
of
the
studies
used
for
the
dietary
risk
assessment
and
other
relevant
information
is
outlined
in
Table
2
.

b.
FQPA
Safety
Factor
The
FQPA
Safety
Factor
was
reduced
to
1X
based
on
the
following
factors:
first,
the
toxicity
database
includes
an
acceptable
two­
generation
reproduction
study
in
rats
and
acceptable
prenatal
developmental
toxicity
studies
in
rats
and
rabbits.
These
studies
show
no
increased
sensitivity
to
fetuses
as
compared
to
maternal
animals
following
acute
in
utero
exposure
in
the
developmental
rat
and
rabbit
studies
and
no
increased
sensitivity
to
pups
as
compared
to
adults
in
a
multi­
generation
reproduction
study
in
rats.
Although
propargite
produced
developmental
effects
in
the
rabbit,
these
effects
were
observed
at
the
maternally
toxic
dose.
Second,
the
Agency
believes
that
its
exposure
assessments
will
not
underestimate
the
potential
dietary
exposures
for
infants
and
children
from
the
use
of
propargite.
Third,
there
are
currently
no
approved
residential
uses
of
propargite.
Based
on
these
factors,
the
additional
10X
factor
as
required
by
FQPA
was
reduced
to
1X.

c.
Population
Adjusted
Dose
(
PAD)

The
PAD
is
a
risk
expression
describing
the
dietary
risk
of
a
chemical,
and
reflects
the
Reference
Dose,
either
acute
or
chronic,
that
has
been
adjusted
to
account
for
the
FQPA
safety
factor
(
i.
e.,
RfD/
FQPA
safety
factor).
In
the
case
of
propargite,
the
FQPA
safety
factor
is
1;
therefore,
the
acute
RfD
equals
the
acute
PAD
and
the
chronic
RfD
equals
the
chronic
PAD.
A
risk
estimate
that
is
less
than
100%
of
the
acute
or
chronic
PAD
does
not
exceed
the
Agency's
risk
concern.
The
Agency's
acute
assessment
concerns
women
of
child­
bearing
age
only,
since
the
toxicological
endpoint
relates
to
developmental
toxicity.
No
suitable
acute
toxicological
endpoint
was
identified
for
the
general
population.

Exposure
Assumptions
Revised
acute
and
chronic
dietary
risk
analyses
for
propargite
were
conducted
with
the
Dietary
Exposure
Evaluation
Model
(
DEEM
 
)
.
DEEM
incorporates
consumption
data
generated
in
USDA's
Continuing
Surveys
of
Food
Intakes
by
Individuals
(
CSFII),
1989­
91.
For
the
acute
dietary
risk
assessment,
the
entire
distribution
of
single
day
food
consumption
events
was
combined
with
a
distribution
of
residues.
This
is
known
as
a
probabilistic
analysis.
Risk
is
reported
at
the
99.9
th
percentile
of
exposure
to
obtain
a
distribution
of
exposure
in
mg/
kg/
day.
For
the
chronic
dietary
risk
assessment,
the
three­
day
average
of
consumption
for
each
sub­
population
is
combined
with
residues
in
commodities
to
determine
average
exposure
in
mg/
kg/
day.

In
the
case
of
propargite,
a
probabilistic
acute
dietary
analysis
was
conducted
utilizing
USDA
Pesticide
Data
Program
(
PDP)
monitoring
data,
field
trial
data,
calculated
livestock
anticipated
residues,
and
percent
crop
treated
information.

e.
Food
Risk
Characterization
Because
no
relevant
effects
following
a
single
dose
of
propargite
were
identified
for
the
U.
S.
general
population,
an
acute
dietary
risk
assessment
for
the
entire
U.
S.
population
was
not
conducted.
However,
an
assessment
was
conducted
for
the
subpopulation
of
women
of
childbearing
age
("
females
13­
50
years
old")
because
developmental
effects
(
birth
defects)
in
rats
were
noted
in
one
developmental
rat
toxicity
study.
The
effects,
skeletal
malformations,
are
presumed
to
occur
after
a
single
exposure
(
dose),
and
thus,
are
appropriate
for
the
acute
risk
assessment.
There
was
no
increased
susceptibility
to
infants
or
children.
Estimated
acute
dietary
exposure
is
below
EPA's
level
of
concern
at
the
99.9th
percentile
(
the
maximum
dietary
risk
estimate
of
2
percent
of
the
aPAD).
28
Estimated
chronic
dietary
risk
estimate
is
also
below
EPA's
level
of
concern.
Less
than
1
percent
of
the
chronic
PAD
for
the
U.
S.
general
population
and
all
population
subgroups
is
estimated.

The
maximum
lifetime
cancer
dietary
risk
is
estimated
to
be
1.8
x
10­
7
for
the
general
U.
S.
population.
Therefore,
the
cancer
risk
from
food
is
also
not
a
concern
since
the
risk
is
less
than
1
x
10­
6.

2.
Dietary
Risk
from
Drinking
Water
Drinking
water
exposure
to
pesticides
can
occur
through
ground
water
and
surface
water
contamination.
EPA
considers
both
acute
(
one
day)
and
chronic
(
lifetime)
drinking
water
risks
and
uses
either
modeling
or,
if
available,
actual
monitoring
data
to
estimate
those
risks.
Modeling
is
generally
considered
to
be
an
unrefined
assessment
and
provides
a
high­
end
estimate
of
risk.

The
GENEEC
and
PRZM­
EXAMS
models
were
used
to
estimate
surface
water
concentrations,
and
SCI­
GROW
was
used
to
estimate
groundwater
concentrations.
Both
of
these
models
are
considered
to
be
screening
tools,
with
the
PRZM­
EXAMS
model
being
somewhat
more
refined
than
the
other
two.
In
addition,
the
Agency
used
time­
weighted
annual
mean
for
propargite
concentrations
in
surface
water
samples
from
the
United
States
Geologic
Survey
National
Water
Quality
Assessment
("
USGS
/
NAWQA")
(
Oristimba
Creek
Watershed)
for
the
years
1992
and
1993.

Propargite
is
moderately
persistent
(
metabolism
half­
lives
=
38­
168
days)
and
immobile
(
K
d
s
ranged
from
60
to
218
mL/
g,
while
K
oc
s
ranged
from
2963
to
57966
mL/
g)
.
It
degrades
rapidly
under
alkaline
hydrolytic
conditions
(
half­
life
=
2.2
days)
and
is
moderately
persistent
to
persistent
under
neutral
(
half­
lives
=
75
days)
and
acid
(
pH
5;
half­
life
=
120
days)
hydrolytic
conditions.
Soil
and
aquatic
photolysis
and
aerobic
and
anaerobic
metabolism
occur
at
moderate
rates
(
half­
lives
=
39­
168
days).
Because
of
its
high
affinity
for
soil
and
sediment,
propargite
has
the
potential
to
move
off
the
site
of
application
during
rainfall,
irrigation,
erosion,
runoff
on
soil
particles
and
by
drift.
Given
the
moderate
to
slow
degradation
rates
for
metabolism
and
photolysis,
and
the
high
K
oc
values,
propargite
will
probably
be
adsorbed
to
sediments
and
organic
material
if
transported
to
surface
waters.
The
Agency
Metabolism
Assessment
Review
Committee
has
concluded
that
the
residue
of
concern
in
plants
and
animals
is
propargite
per
se
and
not
its
metabolites
or
degradate
products.
29
a.
Surface
Water
PRZM­
EXAMS
("
Tier
II")
modeling
was
conducted
as
a
refinement
to
the
drinking
water
exposure
assessment
because
the
GENEEC
("
Tier
I")
surface
water
modeling
predicted
that
the
56­
day
average
propargite
concentrations
in
surface
water
were
likely
to
exceed
the
cancer
drinking
water
level
of
comparison
(
DWLOC).

The
Tier
II
modeling
simulated
average
propargite
a
peak
residue
of
34
ppb
for
the
acute
value,
and
average
residues
of
8.7
ppb
for
the
chronic
value,
and
4.8
for
the
cancer
value.
Since
the
cancer
value
exceeded
the
cancer
DWLOC
of
0.71,
EPA
investigated
the
United
States
Geologic
Survey
("
USGS")
National
Water
Quality
Assessment
("
NAWQA")
monitoring
data
further
to
evaluate
how
it
compared
to
the
modeling
results.
In
that
monitoring
program,
propargite
was
detected
in
175
of
5196
samples
for
the
period
1991
to
1995,
with
a
maximum
concentration
of
20.0
ppb.
The
next
highest
concentration
was
3.7
ppb.
Out
of
the
total
5196
samples,
propargite
was
detected
in
53
of
1000
samples
taken
from
agricultural
streams.
Propargite
was
detected
in
1
of
327
samples
taken
from
urban
streams,
at
a
concentration
of
0.015
ppb.
Propargite
was
detected
in
8
of
245
samples
taken
from
14
integrator
sites
on
large
streams
and
rivers,
with
a
maximum
concentration
of
2.0
ppb.

Propargite
detections
in
the
NAWQA
study
were
predominantly
associated
with
the
San
Joaquin­
Tulare
study
unit
at
intensive­
fixed
monitoring
sites.
This
region
corresponds
with
high
propargite
use
(>
1.526
lb
propargite/
mile2/
year)
in
the
San
Joaquin
region
and
is
associated
primarily
with
beans,
cotton,
and
almond
production.

Although
the
cancer
drinking
water
risk
estimates
from
surface
water
is
above
the
Agency's
level
of
concern,
the
Agency
believes,
in
the
case
of
propargite,
the
modeling
and
monitoring
data
upon
which
the
estimates
are
based
are
conservative
and
overestimates
of
actual
exposure
to
propargite
in
drinking
water
from
surface
water
sources.
The
reasons
for
this
are
described
in
the
next
section
under
"
DWLOCs
for
Cancer."

b.
Ground
Water
A
Tier
I
screening
model,
SCI­
GROW,
was
used
to
provide
an
upper­
end
estimate
of
drinking
water
concentrations
derived
from
ground
water.
The
Agency's
default
body
weights
and
water
consumption
values
used
to
calculate
drinking
water
exposures
are
as
follows:
70
kg/
2L
(
adult
male),
60
kg/
2L
(
adult
female),
and
10
kg/
1L
(
child).
The
predicted
groundwater
concentration
is
0.006
ppb.
Fate
studies
also
suggest
that
propargite
has
a
low
potential
to
reach
groundwater.
Therefore,
the
Agency
does
not
have
a
concern
for
human
exposure
to
propargite
for
drinking
water
from
ground
water
sources.
30
c.
Drinking
Water
Levels
of
Comparison
(
DWLOCs)

To
determine
the
maximum
allowable
contribution
of
water­
containing
pesticide
residues
permitted
in
the
diet,
EPA
first
looks
at
how
much
of
the
overall
allowable
risk
is
contributed
by
food
(
and
if
appropriate,
residential
uses)
then
determines
a
"
drinking
water
level
of
comparison"(
DWLOC)
to
determine
whether
modeled
or
monitoring
levels
exceed
this
level.
The
Agency
uses
the
DWLOC
as
a
surrogate
to
capture
risk
associated
with
exposure
from
pesticides
in
drinking
water.
The
DWLOC
is
the
maximum
concentration
in
drinking
water
which,
when
considered
together
with
dietary
exposure,
does
not
exceed
a
level
of
concern.
In
the
case
of
propargite,
there
are
no
residential
uses,
therefore,
only
food
and
drinking
water
contributions
were
considered.

The
results
of
the
Agency's
drinking
water
analysis
are
summarized
here.
Details
of
this
analysis,
which
used
screening
models
and
actual
monitoring
data,
are
found
in
the
Revised
Human
Health
Risk

Propargite,

is
the
concentration
of
a
pesticide
in
drinking

of
the
aggregate
chronic
exposure
that
results
in
a

Aggregate
Risks
(
Food
and
Water)

An
aggregate
risk
assessment
considers
the
combined
risk
from
dietary
exposure
(
food
and
drinking
water)
and
residential
risk
or
other
non­
occupational
exposures,
when
appropriate.
The
Food
Quality
Protection
Act
amendments
to
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA,
Section
408(
b)(
2)(
A)(
ii))
require
that
for
establishing
a
pesticide
tolerance
"
that
there
is
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
pesticide
chemical
residue,
including
all
anticipated
dietary
exposures
and
other
exposures
for
which
there
are
reliable
information."
Aggregate
exposure
will
typically
include
exposures
from
food,
drinking
water,
and
residential
uses
of
a
pesticide,
and
other
non­
occupational
sources
of
exposure.
When
appropriate,
aggregate
risk
assessments
are
conducted
for
acute
(
one
day),
short­
term
(
one
to
seven
days),
intermediate­
term
(
seven
days
to
several
months),
and
chronic
(
lifetime)
exposure.
Occupational
exposure
is
not
considered
in
any
aggregate
exposure
assessment.

a.
Acute
Aggregate
Risk
The
acute
aggregate
risk
estimates
for
propargite
address
exposure
from
food
and
drinking
water.
There
are
no
residential
uses
of
propargite.
Acute
exposure
is
considered
to
occur
in
a
oneday
time
frame
via
the
oral
route
of
exposure.
Acute
dietary
risks
are
below
the
Agency's
level
of
concern
if
less
than
100
%
of
the
aPAD.
The
estimated
concentrations
of
propargite
in
drinking
water,
which
are
34
ppb
for
surface
water
and
0.006
ppb
for
groundwater,
are
below
the
Agency's
level
of
concern
for
all
subpopulations
including
children
1­
6
years
(
DWLOC
=
2400
ppb).
The
Agency
is,
therefore,
not
concerned
with
aggregate
risks
associated
with
propargite
use.

b.
Chronic
(
Non­
Cancer)
Aggregate
Risk
A
chronic
aggregate
assessment
estimates
risk
from
long
term
exposure
to
food
and
water.
There
are
no
residential
uses
of
propargite.
The
chronic
DWLOC
for
infants
and
Children
is
400
ppb
and
1400
ppb
for
the
general
population,
while
the
EEC
in
surface
water
is
8.7
ppb
and
ground
water
is
0.006
ppb.
The
chronic
EEC
s
are
less
than
than
the
chronic
DWLOCs.
The
Agency
is,
therefore,
not
concerned
with
aggregate
risks
associated
with
propargite
use.

c.
Aggregate
Risk
for
Cancer
The
EECs
for
surface
water
(
4.8
ppb)
were
greater
than
the
cancer
DWLOC
(
0.71
ppb),
indicating
that
the
chronic
exposure
to
propargite
in
food
and
water
is
greater
than
the
Agency's
level
of
concern.
Surface
water
concentrations
below
1.0
ppb
would
result
in
cancer
risks
below
1
x
10­
6
for
drinking
water
alone
when
back
calculated.
Based
on
monitoring
data,
the
time
weighted
average
propargite
concentration
in
ambient
surface
water
samples
from
the
USGS/
NAWQA
(
Oristimba
Creek
Watershed)
for
the
years
1992
and1993
were
0.30
and
1.24
ppb,
respectively.
Therefore,
there
is
a
potential
cancer
risk
of
concern
when
ambient
monitoring
data
are
used
to
estimate
drinking
water
exposure
to
propargite
from
surface
water
sources.

The
EECs
for
groundwater
were
less
than
the
cancer
DWLOC,
and
therefore
not
a
concern.
4.
Occupational
Risk
33
Occupational
workers
can
be
exposed
to
a
pesticide
through
mixing,
loading,
and/
or
applying
a
pesticide,
or
re­
entering
treated
sites.
Occupational
handlers
of
propargite
include:
individual
farmers
or
growers
who
mix,
load,
and/
or
apply
pesticides,
and
professional
or
custom
agricultural
applicators.
Risk
for
all
of
these
potentially
exposed
populations
is
measured
by
a
Margin
of
Exposure
(
MOE)
which
determines
how
close
the
occupational
exposure
comes
to
a
No
Observed
Adverse
Effect
Level
(
NOAEL).
In
the
case
of
propargite,
MOEs
greater
than
100
for
dermal
and
1000
for
inhalation
do
not
exceed
the
Agency's
risk
concern.

a.
Toxicity
The
toxicity
of
propargite
is
integral
to
assessing
the
occupational
risk.
All
risk
calculations
are
based
on
the
most
current
toxicity
information
available
for
propargite.
The
toxicological
endpoints,
and
other
factors
used
in
the
occupational
and
residential
risk
assessments
for
propargite
are

It
is
EPA's
policy
to
combine
chemical
specific
studies
with
similar
surrogate
data
from
the
Pesticide
Handlers
Exposure
Database
(
PHED)
to
assess
handler
exposures
for
regulatory
actions.
This
policy
is
in
effect
because
individual
chemical­
specific
studies
do
not
necessarily
encompass
the
variety
of
equipment
in
use
throughout
the
country
and
the
large
variability
of
exposures
among
handlers.
While
data
from
PHED
provides
the
best
available
information
on
handler
exposures,
it
should
be
noted
that
some
aspects
of
the
included
studies
(
e.
g.,
duration,
acres
treated,
pounds
of
active
ingredient
handled)
may
not
accurately
represent
labeled
uses
in
all
cases.
PHED
was
designed
by
a
Task
Force
of
representatives
from
the
U.
S.
EPA,
Health
Canada,
the
California
Department
of
Pesticide
Regulation,
and
member
companies
of
the
American
Crop
Protection
Association.
The
quality
of
the
data
and
exposure
factors
represents
the
best
sources
of
data
currently
available
to
the
Agency
for
completing
these
kinds
of
assessments;
the
application
rates
are
derived
directly
from
propargite
labels.
The
exposure
factors
(
e.
g.,
body
weight,
amount
treated
per
day,
protection
factors,
etc.)
are
all
standard
values
that
have
been
used
by
the
Agency
over
several
years,
and
the
PHED
unit
exposure
values
are
the
best
available
estimates
of
exposure.
Some
PHED
unit
exposure
values
are
high
quality
while
others
represent
low
quality,
but
are
the
best
available
data.
The
quality
of
the
data
used
for
each
scenario
assessed
is
discussed
in
the
September

Anticipated
use
patterns
and
application
methods,
range
of
application
rates,
and
daily
amount
of
acres
treated
were
derived
from
current

labeling.
Application
rates
specified
on
propargite
labels
range
from
0.5
to
4.5
pounds
of
active
ingredient
per
acre
in
agricultural
settings.
The
Agency
typically
uses
acres
treated
per
day
values
that
are
thought
to
represent
8
hours
of
application
work
for
specific
types
of
application
equipment.

EPA
calculated
the
baseline
MOE
(
short­
term
and
intermediate­
term)
and
cancer
risk
for
each
of
the
exposure
scenarios
using
the
following
baseline
PPE
assumptions:
Long­
sleeved
shirt,
long
pants,
shoes
(
or
boots)
and
socks
(
no
gloves).

If
the
short­
term
or
intermediate­
term
MOE
calculated
using
this
baseline
PPE
was
100
or
greater
for
an
exposure
scenario,
then
no
further
calculations
were
made.
If
the
baseline
short­
term
or
intermediate­
term
MOE
was
less
than
100
for
any
exposure
scenario,
an
additional
short­
term
or
intermediate­
term
MOE
was
calculated
based
on
increasing
the
levels
of
protection
(
additional
PPE).
EPA
calculated
a
short­
term
and/
or
intermediate­
term
MOE
using
additional
PPE
for
each
occupational
exposure
scenario
that
had
baseline
total
MOE
of
less
than
100,
using
the
following
additional
PPE
assumptions:

°

Occupational
Handler
Risk
Summary
EPA
has
determined
that
there
are
potential
exposures
to
mixers,
loaders,
applicators,
or
other
handlers
during
usual
use­
patterns
associated
with
propargite.
Based
on
the
use
patterns
and
potential
exposures
described
above,
14
major
agricultural
exposure
scenarios
are
identified
in
this
document
to
represent
the
extent
of
propargite
uses.

Agricultural
exposure
scenarios
include:
(
1a)
mixing/
loading
liquids
for
aerial
application,
(
1b)
mixing/
loading
liquids
for
chemigation,
(
1c)
mixing/
loading
liquids
for
groundboom
application,
(
1d)
mixing/
loading
liquids
for
orchard
airblast
sprayer
application,
(
1e)
mixing/
loading
liquids
for
application
of
high
pressure
handwand,
(
2a)
mixing/
loading
wettable
powder
for
aerial
application,
(
2b)
mixing/
loading
wettable
powder
for
groundboom
application,
(
2c)
mixing/
loading
wettable
powder
for
orchard
airblast
sprayer
application,
(
2d)
mixing/
loading
wettable
powder
for
application
of
high
pressure
handwand,
(
3)
applying
sprays
with
fixed­
wing
aircraft,
(
4)
applying
sprays
using
a
groundboom
sprayer,
(
5)
applying
sprays
with
an
airblast
sprayer,
(
6)
applying
liquids
with
a
high
pressure
handwand
and
(
7)
flagging
during
aerial
spray
application.

In
most
cases,
EPA
assesses
the
exposure
and
risk
to
mixer/
loaders
and
applicators
separately
for
tractor
drawn
applications
(
i.
e.,
airblast,
groundboom,
and
granular
spreaders).
This
practice
has
evolved,
not
because
it
is
believed
that
there
are
always
separate
job
functions,
but
rather
because
of
the
limited
amount
of
information
regarding
these
practices
along
with
limited
exposure
data.

EPA
has
adopted
a
methodology
to
present
the
risks
separately
for
some
scenarios
and
combine
others.
Most
of
the
hand­
held
equipment
such
as
backpack
sprayers,
and
push
type
granular
spreaders
are
assessed
as
a
combined
function.
With
these
types
of
small
operations
the
mixing,
loading,
and
applying
are
almost
always
carried
out
by
the
same
individual
and
there
are
data
available
to
estimate
exposure
from
these
activities.
For
equipment
such
as
fixed­
wing­
aircraft,
groundboom
tractors,
and
airblast
sprayers
the
applications
are
assessed
separately
from
the
individual
who
mixes
and
loads
the
formulated
product.
EPA
assumes
that
the
pilots
are
rarely
involved
in
the
mixing/
loading.
By
separating
the
two
job
functions,
EPA
can
determine
the
most
appropriate
PPE
37
or
engineering
control
without
requiring
the
handler
to
wear
PPE
throughout
the
entire
workday
or
engineering
controls
that
are
not
needed.

The
potential
handler
exposures
are
assessed
using
the
toxicological
endpoints
and
uncertainty
factors
associated
with
the
active
ingredient.
Therefore,
the
PPE
and
engineering
controls
are
determined
by
the
assessment
of
the
active
ingredient
and
not
the
currently
required
risk
mitigation
measures
on
propargite
labels.
This
distinction
of
determining
risk
mitigation
measures
based
on
the
active
ingredient
instead
of
the
label
required
PPE
is
also
important
because
of
the
nature
of
the
enduse
products.
For
example,
some
end­
use
products
require
additional
PPE
that
are
not
necessary
for
the
active
ingredient
but
rather
because
of
the
end­
use
product's
potential
for
eye
and/
or
skin
irritation
based
on
other
ingredients
of
the
formulation.
Conversely,
the
Agency
does
not
want
to
mandate
additional
PPE
(
e.
g.,
heat
stress
issues)
if
the
PPE
ensemble
is
not
required
based
on
the
endpoint
and
uncertainty
factors.

Agricultural

Risk
Table
8
below
summarizes
the
numeric
MOE
values
for
both
the
short
and
intermediate­
term
exposure
durations
as
well
as
cancer
risk
estimates.
In
the
majority
of
cases,
dermal
exposure
rather
than
inhalation
exposure
contributes
relatively
more
exposure
(
dermal
and
inhalation
exposures
were
not
combined
in
this
assessment
for
the
short
and
intermediate­
term
MOEs.
However,
dermal
and
inhalation
exposures
were
added
for
the
cancer
risk
estimates).
The
MOEs
are
presented
for
baseline,
PPE
and
engineering
controls.
Cancer
risk
estimates
are
also
summarized
at
different
levels
of
mitigation.
MOEs
100
or
above
are
not
a
concern
for
dermal
exposure,
while
MOEs
1000
or
above
are
required
to
be
above
the
Agency's
level
of
concern
for
inhalation
exposure
(
and
extra10X
factor
is
included
due
to
lack
of
a
NOAEL,
severity
of
effects
at
the
lowest
dose
tested,
and
4
hour
duration).
The
target
for
cancer
risk
is
1
x
10­
6,
however,
the
Agency
will
not
accept
risks
above
1
x
10­
4.
For
risks
between
1
x
10­
6
and
1
x
10­
4,
the
Agency
will
pursue
risk
mitigation
where
feasible.

Post­
Application
Occupational
Risk
The
post­
application
occupational
risk
assessment
considered
exposures
to
workers
entering
treated
sites.
EPA
has
determined
that
there
are
potentially
significant
short
and
intermediate­
term
post­
application
exposures
to
workers
entering
treated
fields
for
post­
treatment
activities,
e.
g.,
weeding,
pruning,
irrigating,
harvesting.

Table
9
below
summarizes
the
Agency's
risk
assessment
for
workers,
based
on
various
activities
and
application
rates
for
each
crop.
This
table
shows
the
number
of
days
that
must
pass
after
propargite
is
applied
before
the
risk
is
above
the
Agency's
level
of
concern
(
MOE
$
100
for
intermediate­
term
dermal
exposure).
The
table
also
shows
the
life­
time
cancer
risk
that
would
result
if
workers
were
to
re­
enter
a
propargite
treated
field
on
the
first
day
the
MOE
$
100
for
35
years.

The
re­
entry
interval
(
REI)
is
the
period
of
time
after
propargite
application
(
expressed
in
days)
that
must
elapse
before
an
unprotected
worker
may
re­
enter
the
field
to
perform
a
given
operation.
The
REI
is
established
for
a
crop
by
considering
the
worker
activities
associated
with
the
crop
and
determining
the
number
of
days
after
treatment
must
elapse
before
a
the
risk
is
no
longer
a
concern.
Typically,
the
activity
with
the
highest
risk
will
drive
the
selection
of
the
appropriate
REI
for
the
crop.
All
of
the
post­
application
risk
calculations
for
handlers
completed
in
this
assessment
are
included
in
the
July
31,
2001
document
entitled,
"

Occupational

Residential
Exposure

Human
Incident
Data
The
Agency
consulted
and
reviewed
several
sources
of
information
on
health
incidents
involving
human
exposure,
finding
a
history
of
propargite
cases
mostly
related
to
handler
and
worker
exposure.
The
general
incident
trend,
however,
appears
to
be
downward.
The
four
sources
of
information
are
OPP's
Incident
Data
System
(
IDS),
American
Association
of
Poison
Control
Centers
(
PCC),
California
Department
of
Pesticide
Regulation
(
CDPR),
and
the
National
Pesticides
Telecommunication
Network.
CDPR
and
OPP
data
tend
to
provide
the
most
insight
into
propargite's
association
with
human
health
incidents.
Detailed
descriptions
of
the
above
sources
and
the
cases
involving
propargite
are
provided
in
the
human
health
risk
assessment.

The
incident
data
contain
cases
showing
propargite
poses
skin
illness
and
eye
irritation
concerns
for
handlers
and
post­
application
workers.
From
CDPR
data,
field
residue
exposure
was
associated
with
the
majority
(
66%)
of
the
exposures
cases
in
California.
A
large
proportion
of
cases
resulted
from
field
reentry
and
worker
activities
involving
extensive
contact
with
treated
foliage
such
as
turning
cane
for
grapes
and
harvesting
citrus.
Applicators
and
other
handlers
accounted
for
the
bulk
of
the
balance
(
28%).
These
data
illustrate
that
human
incidents
have
historically
occurred
mostly
among
workers
and
handlers.

Propargite
usually
effects
the
skin
in
human
exposure
cases.
Of
the
confirmed
propargite
cases
reported
to
the
CDPR
between
1982
and
1996,
79%
of
the
individuals
developed
skin
illnesses
as
a
result
of
exposure
(
528
of
671
persons).
Data
covering
the
years
1982­
1989
found
that
propargite
was
the
leading
cause
of
skin­
related
injuries
among
all
pesticides
in
California.
For
the
years
1990­
1994,
propargite
dropped
to
seventh
place
among
pesticides.
The
drop
in
the
frequency
47
of
illnesses
in
the
early
1990'
s
is
apparently
attributable
to
increasing
restricted
entry
intervals
(
REI),
which
were
put
into
place
in
1989.
Depending
on
the
crop,
REIs
were
extended
from
2­
7
days
to
14­
42
days.
Promulgation
of
the
final
Worker
Protection
Standard
regulations
in
the
1990'
s
may
have
also
contributed
to
the
reduction
of
incidents.
In
addition,
the
registrant
fielded
a
voluntary
product
stewardship
program
during
this
same
time
frame,
presumably
facilitating
greater
compliance
with
labels
by
educating
handlers
and
workers.

Notwithstanding
the
number
and
types
of
exposure
cases,
both
PCC
and
CDPR
data
indicate
that
incidents
rarely
result
in
hospitalization
or
long,
prolonged
absences
from
work.
In
some
cases,
the
skin
effects
may
be
severe
and
absences
from
work
are
significant.
Nonetheless,
compared
to
all
other
pesticides,
propargite
has
a
favorable
profile
suggesting
low
risk
of
moderate
or
serious
effects.
Despite
the
downward
trend
in
exposure
cases,
incidents
still
occur
on
a
regular
basis
involving
field
workers,
suggesting
additional
mitigation
may
be
warranted
on
certain
crops.

B.
Environmental
Risk
Assessment
A
summary
of
the
Agency's
environmental
risk
assessment
is
presented
below.
For
detailed
discussions
of
all
aspects
of
the
environmental
risk
assessment,
see
the
Environmental
Fate
and
Effects
Division
Science
Chapter
for
Reregistration
Eligibility
Document
for
Propargite,
dated
June
7,
2000,
available
in
the
public
docket.

1.
Environmental
Fate
and
Transport
Propargite
is
moderately
persistent
(
metabolism
half­
lives
=
38­
168
days)
and
immobile
(
K
d
s
ranged
from
60
to
218
mL/
g,
while
K
oc
s
ranged
from
2963
to
57966
mL/
g)
.
It
degrades
rapidly
under
alkaline
hydrolytic
conditions
(
half­
life
=
2.2
days)
and
is
moderately
persistent
to
persistent
under
neutral
(
half­
lives
=
75
days)
and
acid
(
pH
5
half­
life
=
120
days)
hydrolytic
conditions.
Soil
and
aquatic
photolysis
and
aerobic
and
anaerobic
metabolism
occur
at
moderate
rates
(
half­
lives
=
39­
168
days).
Degradates
are
carbon
dioxide,
propargite
glycol
ether
(
TBPC,
2­[
4­(
1,1­
dimethylethyl)
phenoxy]
cyclohexane­
1­
ol,
also
identified
as
2­(
p­
tertiarybutyl
phenoxycyclohexanol
and
PTBP
(
p­
tertiary
butylphenoxy
cyclohexanol.
However,
the
Agency
Metabolism
Assessment
Review
Committee
has
concluded
that
the
residue
of
concern
in
plants
and
animals
is
propargite
per
se
and
not
its
metabolites
or
degradate
products.
Because
of
its
high
affinity
for
soil
and
sediment,
propargite
has
the
potential
to
move
off
the
site
of
application
during
rainfall/
irrigation
by
erosion/
runoff
on
soil
particles
and
by
drift.
Given
the
moderate
to
slow
degradation
rates
for
metabolism
and
photolysis,
and
the
high
K
oc
values,
propargite
will
probably
be
adsorbed
to
sediments
and
organic
material
if
transported
to
surface
waters.

2.
Ecological
Toxicity
The
Agency's
ecological
risk
assessment
compares
toxicity
endpoints
from
ecological
toxicity
studies
to
estimated
environmental
concentrations
based
on
environmental
fate
characteristics,
pesticide
use,
and/
or
monitoring
data.
To
evaluate
the
potential
risk
to
nontarget
organisms
from
the
use
of
propargite
products,
EPA
calculates
a
Risk
Quotient
(
RQ),
which
is
the
ratio
of
the
estimated
exposure
concentration
to
the
toxicity
endpoint
values,
such
as
the
LC
50
(
the
median
concentration
of
a
substance
which
causes
death
to
50%
of
the
test
animals).
The
RQ
is
simply
a
means
of
integrating
the
results
of
ecological
exposure
and
ecological
toxicity.
These
RQ
values
are
compared
to
levels
of
concern
(
LOCs),
which
provide
an
indication
of
the
relative
risk
the
particular
pesticide
and/
or
use
may
pose
for
nontarget
organisms.
If
the
RQ
does
not
exceed
the
LOC,
it
is
unlikely
that
the
pesticide
will
pose
a
significant
risk.
Similarly,
when
RQs
are
equal
to
or
greater
than
the
LOC,
additional
refinements
or
mitigation
may
be
necessary.
Use,
toxicity,
fate,
and
exposure
are
considered
to
characterize
the
risk
as
well
as
the
level
of
certainty
and
uncertainty
in
the
assessment.
EPA
further
characterizes
ecological
risk
based
on
any
reported
aquatic
or
terrestrial
incidents
to
nontarget
organisms
in
the
field
(
e.
g.,
fish
or
bird
kills).

Based
on
toxicity
studies
submitted
by
the
Registrant,
propargite
poses
a
potential
for
adverse
effects
on
reproduction
in
birds
and
mammals.
Risk
to
aquatic
organisms
and
plants
is
generally
lower
than
the
risk
for
birds
and
mammals;
however,
the
chronic
risk
concern
levels
for
freshwater
invertebrates
and
freshwater
fish
are
either
approached
or
exceeded
for
over
60
days
from
multiple
propargite
applications.

a.
Risk
to
Birds
and
Mammals
EPA's
assessment
suggests
that
the
most
significant
ecological
risk
posed
by
the
use
of
propargite
is
the
potential
for
adverse
effects
on
reproduction
in
birds
and
mammals.
The
assessment
indicates
that
reproduction
risk
to
birds
may
occur
where
propargite
is
applied
a
single
time
at
0.5
lb
active
ingredient
per
acre
or
greater.
Concerns
for
reproduction
risk
to
mammals
are
triggered
at
application
rates
of
1.6
lb
ai/
A
or
greater.
These
concerns
are
heightened
when
multiple
applications
of
propargite
are
factored
into
the
assessment.
Multiple
applications
of
a
pesticide
may
raise
the
risk
to
an
organism
by
increasing
the
concentration
of
residues
on
food
items
and
by
extending
the
period
during
which
these
residues
may
be
present.
EPA's
conclusions
for
propargite's
potential
effects
to
birds
and
mammals
are
based
on
the
following
labeled
use
rates
and
numbers
of
applications:
2
applications
at
4.5
lb
ai/
A;
2
applications
at
3
lb
ai/
A;
2
applications
at
2
lb
ai/
A;
and
2
or
3
applications
at
1.6
lb
ai/
A.

The
timing
of
propargite
applications
to
control
target
pests
coincides
with
breeding
seasons
of
some
birds
common
to
the
labeled
crop
areas.
This
could
expose
nesting
birds
and
their
developing
young
to
residues
which
could
negatively
impact
their
reproductive
success.
The
chronic
effects
to
birds
reported
in
registrant­
submitted
studies
included
reductions
in
mean
numbers
of
eggs
laid/
female(
mallard
and
bobwhite),
viable
embryos
(
mallard),
live
3­
week
embryos
(
mallard),
hatch
success
(
mallard),
hatchling
survival
and
weight
(
mallard
and
bobwhite),
and
adult
body
weight
49
change
(
mallard)
at
dietary
concentration
of
288
ppm.
At
a
dietary
concentration
of
84.7
ppm,
slight
reductions
were
also
observed
in
adult
body
weight
change
(
bobwhite
and
mallard),
eggs
laid/
female,
live
embryos,
and
hatchling
survival.

With
the
exception
of
multiple
applications
at
4.5
lb
ai/
A
(
RQ
=
0.59
for
species
expected
to
ingest
high
amounts
of
short
grass
or
foliage),
avian
acute
risk
assessment
scenarios
for
propargite
did
not
exceed
acute
risk
level
of
concern
(
LOC
=
3401
ppm)
for
birds.
LOCs
for
acute
risk
are
approached,
but
not
exceeded
for
multiple
applications
at
3
lb
ai/
A.
Shorter
application
intervals
could
increase
exposure
and
risk
for
these
scenarios.
A
number
of
application
scenarios
triggered
the
restricted
use
criteria
at
rates
of
1.6
lb
ai/
A
and
above
(
RQ>
0.2).
For
acute
toxicity
to
endangered
avian
species,
all
multiple
application
scenarios
assessed
exceeded
the
LOC
(
RQ>
0.1)
for
short
and
tall
grass
and
broadleaf
plants.
RQs
for
acute
effects
to
birds
ingesting
primarily
fruits
and
seeds
were
below
levels
of
concern
for
acute
risk,
restricted
use,
and
endangered
species.

The
assessment
suggests
the
potential
for
acute
effects
to
mammals
for
multiple
applications
at
the
highest
labeled
rate
of
~
4.5
lb
ai/
A
(
walnut,
and
avocado).
Levels
of
concern
for
acute
risk
are
approached
but
not
exceeded
for
multiple
applications
at
3
lb
ai/
A.
Mammalian
chronic
levels
of
concern
(
400
ppm
exposure
levels)
may
be
exceeded
at
single
application
rates
over
1.6
lb
ai/
A
(
which
is
allowed
for
many
crop
uses
of
propargite)
and
at
multiple
application
rates
above
0.75
lb
ai/
A
which
are
allowed
for
all
crop
uses.
However,
there
were
a
number
of
LOCs
for
the
acute
restricted
use
that
were
exceeded
for
herbivorous
or
herbivorous/
insectivorous
mammals
(
RQs
>
0.2)
based
on
terrestrial
exposure
scenarios.
There
are
acute
endangered
species
risk
concerns
for
herbivorous
or
herbivorous/
insectivorous
mammals
(
RQs>
0.1)
for
many
uses.
Granivorous
mammals
are
not
predicted
to
be
exposed
to
residues
that
could
result
in
acute
effects.

The
lack
of
data
on
propargite
persistence
on
foliage
and
other
avian
and
mammalian
food
items
is
a
source
of
uncertainty
in
the
terrestrial
risk
assessment.
Because
no
data
were
available,
a
default
foliar
half­
life
of
30
days
was
assumed.
Foliar
dissipation
is
not
expected
to
be
rapid,
however,
because
of
propargite's
photolytic
stability,
slow
hydrolysis
at
neutral
pH
values,
and
low
vapor
pressure.
Rainfall
could
result
in
residue
washoff
thereby
reducing
terrestrial
exposure.
Reapplication
could
result
in
repeated
exposure
of
terrestrial
organisms
to
propargite
residues.

b.
Risk
to
Aquatic
Species
The
standard
method
for
assessing
aquatic
risk
results
in
concern
for
potential
chronic
effects
to
freshwater
fish
and
invertebrates.
Although
EPA's
criteria
for
acute
risk
to
freshwater
invertebrates
and
estuarine
fish
were
not
exceeded,
the
assessment
suggests
that
adverse
effects
could
occur
in
shallow
bodies
of
water
that
are
not
represented
by
standard
scenarios.
No
data
are
available
to
assess
risk
to
estuarine
and
marine
organisms.
Also,
as
noted
for
the
terrestrial
risk
assessment,
an
element
of
uncertainty
is
added
to
the
aquatic
risk
assessment
by
the
lack
of
established
application
intervals
on
propargite
labels.
The
time
between
applications
could
have
an
impact
on
exposure
levels
used
to
assess
aquatic
risk.
50
Chronic
toxicity
effect
levels
were
low
for
freshwater
aquatic
invertebrates
and
fish.
Given
the
persistence
characteristics
of
propargite,
the
potential
for
chronic
effects
is
most
likely
if
residues
reach
aquatic
habitats
in
concentrations
exceeding
9­
16
ug/
L
(
the
Daphnia
magna
No
Observable
Effect
Concentration
[
NOEC]
=
9
ug/
L;
fathead
minnow
NOEC
=
16
ug/
L).
Chronic
LOCs
for
invertebrates
were
exceeded
in
three
of
the
five
scenarios
in
Tier
II
modeling
simulations.
There
were
no
data
available
to
assess
potential
chronic
effects
to
estuarine
and
marine
organisms.
In
aerobic
and
anaerobic
aquatic
metabolism
studies,
propargite
half­
lives
were
38
and
46
days,
respectively.
These
data,
along
with
hydrolysis
half­
lives
of
75
and
120
days
at
pH
7
and
5,
respectively,
suggest
that
propargite
will
be
relatively
persistent
in
aquatic
environments.
Any
impact
on
aquatic
life,
then,
is
likely
to
be
greatest
where
neutral
to
acidic
conditions
predominate
(
pH
5.0
to
7.0).
This
could
include
tributaries
fed
by
acid
drainage
or
that
receive
runoff
from
watersheds
where
highly
organic
soils
predominate.
Because
aqueous
photolysis
of
residues
is
not
an
important
process,
water
clarity
is
not
likely
to
play
an
important
role
in
degradation.
Because
of
its
high
affinity
for
soil,
propargite
has
the
potential
to
move
into
aquatic
habitats
through
runoff
or
wind
erosion
of
soil
particles.
Other
offsite
transport
is
possible
by
spray
drift
from
aerial,
airblast,
or
ground
boom
applications.
Given
the
moderate
to
slow
degradation
rates
for
metabolism
and
photolysis,
and
the
high
K
oc
values,
propargite
is
likely
to
partition
to
sediment
and
organic
material
found
in
surface
waters.
Thus,
impacts
to
benthic­
dwelling
organisms
from
prolonged
exposure
to
contaminated
sediments
must
be
a
consideration
when
characterizing
long­
term
risk
potential
for
exposed
aquatic
areas.
Toxicity
to
these
organisms
from
residues
on
sediment
is
uncertain
because
relevant
data
are
not
available.

Though
propargite
is
highly
toxic
to
all
fish
and
invertebrate
species
tested
(
96
hour
LC
50
values
for
7
aquatic
species
were
below
168
ug/
L),
the
RQs
calculated
from
EECs
derived
from
Tier
II
simulations
suggest
little
potential
for
acute
risk
to
fish
or
invertebrates.
However,
several
RQs
ranged
between
0.2
and
0.5
suggesting
that
exposure
in
small,
shallow
water
bodies
(
i.
e.,
those
not
represented
by
EPA's
standard
aquatic
risk
scenario)
could
result
in
adverse
effects
to
organisms
present.
Acute
restricted
use
exceedences
(
RQ=
0.2)
for
fish
and
invertebrates
are
noted
for
a
number
of
application
scenarios.
For
endangered
aquatic
species,
all
modeled
scenarios
exceeded
Agency
acute
levels
of
concern
(
RQ>
0.05).

c.
Endangered
Species
At
currently
proposed
rates,
endangered
species
risk
presumption
levels
are
exceeded
for
both
freshwater
and
estuarine/
marine
fish
and
invertebrates
at
the
label
permitted
application
scenarios
for
propargite.
Although
concern
levels
for
estuarine
invertebrates
are
exceeded,
there
are
no
federally
listed
estuarine
invertebrates.
Mammalian
and
avian
acute
risk
for
endangered
species
is
exceeded
for
certain
species
which
may
feed
heavily
on
vegetation
or
insects.
Chronic
risk
concern
levels
for
listed
birds
and
mammals
are
indicated
for
many
uses.

The
Agency
consulted
with
the
US
Fish
and
Wildlife
Service
(
FWS
or
the
Service)
on
the
corn
use
of
propargite
as
part
of
the
corn
cluster
analysis
in
1983
and
on
several
agricultural
uses
of
propargite
in
the
"
reinitiation"
of
the
cluster
assessments
in
1988.
The
resulting
Opinions
found
51
jeopardy
to
one
amphibian
species,
eight
fish
species
and
one
invertebrate
species.
The
Service
proposed
Reasonable
and
Prudent
Alternatives
(
RPAs)
to
avoid
the
likelihood
of
jeopardizing
the
continued
existence
of
these
species.
In
addition,
the
Service
had
Reasonable
and
Prudent
Measures
(
RPMs)
to
reduce
incidental
take
of
22
fish
and
one
aquatic
invertebrate
species.
These
consultations
and
the
findings
expressed
in
the
Opinions,
however,
are
based
on
old
labels
and
application
methods,
less
refined
risk
assessment
procedures,
and
an
older
approach
to
consultation
which
is
currently
being
revised
through
interagency
collaboration.

EPA's
current
assessment
of
ecological
risks
uses
both
more
refined
methods
to
define
ecological
risks
of
pesticides
and
new
data,
such
as
that
for
spray
drift.
Therefore,
the
Reasonable
and
Prudent
Measures
(
RPMs)
in
the
Biological
Opinion(
s)
may
need
to
be
reassessed
and
modified
based
on
these
new
approaches.

The
Agency
is
currently
engaged
in
a
Proactive
Conservation
Review
with
FWS
and
the
National
Marine
Fisheries
Service
under
section
7(
a)(
1)
of
the
Endangered
Species
Act.
The
objective
of
this
review
is
to
clarify
and
develop
consistent
processes
for
endangered
species
risk
assessments
and
consultations.
Subsequent
to
the
completion
of
this
process,
the
Agency
will
reassess
the
potential
effects
of
propargite
use
to
federally
listed
threatened
and
endangered
species.
At
that
time,
the
Agency
will
also
consider
any
regulatory
changes
recommended
in
the
RED
that
are
being
implemented.
Until
such
time
as
this
analysis
is
completed,
the
overall
environmental
effects
mitigation
strategy
articulated
in
this
document
and
any
County
Specific
Pamphlets
described
below
which
address
propargite,
will
serve
as
interim
protection
measures
to
reduce
the
likelihood
that
endangered
and
threatened
species
may
be
exposed
to
propargite
at
levels
of
concern.

3.
Ecological
Incidents
The
Agency
incident
database
contains
a
single
incident
with
propargite.
The
incident
involved
crop
injury
to
82
acres
of
newly
planted
cotton
crops
in
Arvin,
CA.
Propargite,
chlorpyrifos,
and
amitraz
were
all
applied.
Propargite
(
Comite)
labels
warn
against
possible
phytotoxicity
to
young
cotton
plants.

No
mortality
incidents
with
wildlife,
non­
target
insects,
or
aquatic
organisms
have
been
reported
for
propargite.
However,
the
types
of
chronic
concerns
for
birds
and
mammals
expressed
for
propargite
are
unlikely
to
be
observed
in
normal
usage.
Also,
acute
mortality
to
non
target
invertebrates
(
terrestrial
or
aquatic)
is
generally
not
observed
or
reported
in
incident
reports,
even
when
high
mortality
is
reported
for
birds,
mammals,
amphibians
or
fish.

IV.
Risk
Management
and
Reregistration
Decision
A.
Determination
of
Reregistration
Eligibility
Section
4(
g)(
2)(
A)
of
FIFRA
calls
for
the
Agency
to
determine,
after
submissions
of
relevant
data
concerning
an
active
ingredient,
whether
products
containing
the
active
ingredient
are
eligible
for
reregistration.
The
Agency
has
previously
identified
and
required
the
submission
of
the
generic
(
i.
e.,
an
active
ingredient
specific)
data
required
to
support
reregistration
of
products
containing
the
active
ingredient
propargite.

The
Agency
has
completed
its
assessment
of
the
occupational,
non­
occupational,
and
ecological
risks
associated
with
the
use
of
pesticides
containing
the
active
ingredient
propargite,
as
well
as
a
propargite­
specific
dietary
risk
assessment.
Based
on
a
review
of
these
data
and
on
public
comments
on
the
Agency's
assessments
for
the
active
ingredient
propargite,
EPA
has
sufficient
information
on
the
human
health
and
ecological
effects
of
propargite
to
make
decisions
as
part
of
the
tolerance
reassessment
process
under
FFDCA
and
reregistration
process
under
FIFRA,
as
amended
by
FQPA.
The
Agency
has
determined
that
propargite
products
are
eligible
for
reregistration
provided
that:
(
i)
current
data
gaps
and
additional
confirmatory
data
needs
are
addressed;
(
ii)
the
risk
mitigation
measures
outlined
in
this
document
are
adopted,
and
(
iii)
label
amendments
are
made
to
reflect
these
measures.
Label
changes
are
described
in
Section
V.
Appendix
A
summarizes
the
uses
of
propargite
that
are
eligible
for
reregistration.
Appendix
B
identifies
the
generic
data
requirements
that
the
Agency
reviewed
as
part
of
its
determination
of
reregistration
eligibility
of
propargite,
and
lists
the
submitted
studies
that
the
Agency
found
acceptable.
Data
gaps
are
identified
as
generic
data
requirements
that
have
not
been
satisfied
with
acceptable
data.

Based
on
its
evaluation
of
propargite,
the
Agency
has
determined
that
propargite
products,
unless
labeled
and
used
as
specified
in
this
document,
would
present
risks
inconsistent
with
FIFRA.
Accordingly,
should
a
registrant
fail
to
implement
any
of
the
risk
mitigation
measures
identified
in
this
document,
the
Agency
may
take
regulatory
action
to
address
the
risk
concerns
from
use
of
propargite.
If
all
changes
outlined
in
this
document
are
incorporated
into
the
product
labels,
then
all
current
risks
for
propargite
will
be
adequately
mitigated
for
the
purposes
of
this
determination.

B.
Summary
of
Public
Comments
and
Responses
When
making
its
initial
reregistration
decision
in
2001,
the
Agency
took
into
account
all
comments
received
after
opening
of
the
public
docket.
These
comments
in
their
entirety
are
available
in
the
docket.
A
summary
of
the
comments
and
the
Agency
response
is
noted
below.

Comment:
During
the
public
comment
period
provided
for
the
preliminary
risk
assessment,
EPA
received
comments
from
the
Almond
Hullers
and
Processors
Association
and
the
National
Agricultural
Aviation
Association
(
NAAA).
The
Almond
Hullers
and
Processors
Association
questioned
the
appropriateness
of
the
transfer
coefficients
that
EPA
used
to
determine
postapplication
risks.
The
Almond
Hullers
also
expressed
concern
that
the
31­
day
REI
that
was
proposed
53
in
the
preliminary
risk
assessment
was
too
long.
The
Almond
Hullers
also
asked
for
guidance
on
what
activities
would
be
restricted
by
the
REI.

Response:
EPA
has
revised
the
post­
application
risk
assessment
using
new
transfer
coefficients
derived
from
the
Agricultural
Reentry
Task
Force
(
ARTF).
These
new
transfer
coefficients
can
be
found
in
the
Science
Advisory
Council
for
Exposure,
Policy
number
3.1
dated
August
7,
2000.
The
propargite
RED
uses
the
standard
values
found
in
this
new
policy
unless
a
chemical/
crop
specific
study
is
available,
as
was
the
case
for
tree
shakers
for
nut
crops
(
MRID
418486­
04).
As
a
result
of
using
the
new
transfer
coefficients,
the
REI
for
almonds
(
at
maximum
use
rate
of
3lbs
ai/
A)
is
now
22
days.
Many
of
the
other
activities
of
concern
to
almond
growers
can
be
accommodated
with
existing
exemptions
under
the
Worker
Protection
Standard.
Scouting
is
a
handler
activity
under
the
WPS,
so
anyone
performing
this
activity
may
legally
enter
the
treated
field
during
the
REI
provided
they
use
the
handler
personal
protective
equipment
(
PPE)
specified
on
the
label.
In
addition,
if
the
scout
is
a
certified
crop
advisor
as
defined
in
the
WPS
(
40CFR170.112(
e)),
the
individual
can
determine
the
appropriate
PPE
to
be
used.
For
many
of
these
crops,
irrigation
equipment
is
not
routinely
moved
by
hand.
For
these
methods,
the
primary
activity
involves
entering
the
field
to
turn
the
watering
equipment
on
and
off.
This
activity
is
allowed
during
the
REI
under
the
no
contact
exception
to
WPS
(
40CFR170.112(
b)).
Should
irrigation
equipment
need
unexpected
repairs
during
the
REI,
WPS
allows
workers
to
enter
a
treated
field
provided
early
entry
PPE
is
used
(
40CFR170.112(
c)).
This
exception
also
applies
to
mechanical
harvesting,
tree
shaking
or
winrowing
for
nut
crops
in
enclosed
cabs,
and
often
applies
to
mowing.

Comment:
The
NAAA
was
concerned
that
EPA's
occupational
risk
assessment
for
propargite
is
based
on
out­
of­
date
data
that
are
not
reflective
of
current
practices.
Their
comments
specifically
mentioned
that
technological
advances
such
as
use
of
Global
Positioning
Satellite
(
GPS)
and
automatic
flagging
systems
have
replaced
human
flagging;
and
mixers/
loaders
for
aerial
applicators
routinely
use
personal
protective
equipment
and
engineering
controls,
such
as
closed
mixing
loading
systems,
body
suits,
respirators
and
other
equipment.

Response:
The
risk
mitigation
measures
outlined
in
this
RED
are
consistent
with
the
standard
practices
that
are
currently
followed
in
the
industry,
as
described
by
the
NAAA
comments
on
propargite.
Based
on
the
risk
assessment,
there
will
be
no
new
requirements
for
human
flaggers;
closed
mixing/
loading
systems
will
be
required
for
aerial
applications
of
propargite
for
corn
and
cotton;
and
enclosed
cockpits
will
be
required.
With
these
risk
mitigation
measures
in
place,
EPA
believes
that
risks
will
not
be
unreasonable.

Other
Comments:
Subsequent
to
the
comment
period
for
the
propargite
preliminary
risk
assessment,
EPA
also
received
a
series
of
letters
and
e­
mails
attesting
to
the
benefits
of
propargite.

C.
Regulatory
Position
1.
FQPA
Assessment
a.
"
Risk
Cup"
Determination
As
part
of
the
FQPA
tolerance
reassessment
process,
EPA
assessed
the
risks
associated
with
this
pesticide.
EPA
has
determined
that
risk
from
dietary
(
food
sources
only)
exposure
to
propargite
is
within
its
own
"
risk
cup."
In
other
words,
EPA
has
concluded
that
the
tolerances
for
propargite
meet
the
FQPA
safety
standards.
In
reaching
this
determination
EPA
has
considered
the
available
information
on
the
special
sensitivity
of
infants
and
children,
as
well
as
the
acute
and
chronic
food
exposure.
An
aggregate
assessment
was
conducted
for
exposures
through
food
and
drinking
water
exposure
only
since
there
are
no
residential
uses
of
propargite.
Results
of
this
aggregate
assessment
indicate
that
the
human
health
risks
from
these
combined
exposures
are
within
acceptable
levels;
that
is,
that
is,
when
aggregated,
propargite
exposures
fit
within
the
risk
cup.

Therefore,
there
are
no
changes
in
propargite
tolerances
due
to
risk
concerns
and
most
tolerances
will
remain
in
effect
(
except
the
dried
citrus
pulp,
poultry
meat
and
meat
by­
products
tolerances
are
no
longer
needed
for
other
reasons
discussed
below).
The
Agency
will
establish
tolerances
for
aspirated
grain
fractions;
cotton
gin
byproducrts,
and
citrus
oil.

b.
Determination
of
Safety
for
U.
S.
Population
EPA
has
determined
that
the
established
tolerances
for
propargite,
with
amendments
and
changes
as
specified
in
this
document,
meet
the
safety
standards
under
the
FQPA
amendments
to
section
408(
b)(
2)(
D)
of
the
FFDCA,
that
there
is
a
reasonable
certainty
of
no
harm
for
the
general
population.
In
reaching
this
determination,
EPA
has
considered
all
available
information
on
the
toxicity,
use
practices,
and
scenarios,
and
the
environmental
behavior
of
propargite.
As
discussed
in
chapter
3,
the
acute
and
chronic
dietary
(
food
alone)
risk
is
below
the
level
of
concern,
as
is
the
cancer
dietary
risk
from
food
alone.
Regarding
risks
from
drinking
water
exposures,
acute
and
chronic
risks
from
drinking
water
are
not
of
concern
for
surface
or
groundwater
supplies,
and
although
the
projected
surface
water
concentrations
exceed
the
Agency's
cancer
concern
level,
the
Agency
believes
that
those
projections
are
conservative
and
over­
estimate
the
human
exposure
to
propargite
that
will
result
from
drinking
water
sources
from
surface
water
(
See
Regulatory
Rationale
55
under
Drinking
Water
in
section
IV.
D.
1.
a.
iv.).

c.
Determination
of
Safety
for
Infants
and
Children
EPA
has
determined
that
the
established
tolerances
for
propargite,
with
amendments
and
changes
as
specified
in
this
document,
meet
the
safety
standards
under
the
FQPA
amendments
to
section
408(
b)(
2)(
C)
of
the
FFDCA,
that
there
is
a
reasonable
certainty
of
no
harm
for
infants
and
children.
The
safety
determination
for
infants
and
children
considers
the
factors
noted
above
for
the
general
population,
but
also
takes
into
account
the
possibility
of
increased
dietary
exposure
due
to
the
specific
consumption
patterns
of
infants
and
children,
as
well
as
the
possibility
of
increased
susceptibility
to
the
toxic
effects
of
propargite
residues
in
this
population
subgroup.

In
determining
whether
or
not
infants
and
children
are
particularly
susceptible
to
toxic
effects
from
propargite
residues,
EPA
considered
the
completeness
of
the
database
for
developmental
and
reproductive
effects,
the
nature
of
the
effects
observed,
and
other
information.
An
FQPA
safety
factor
is
not
required
for
propargite
because
(
1)
the
toxicology
database
is
complete
for
the
FQPA
assessment,
and
provides
no
indication
of
increases
susceptibility
of
young
rats
or
rabbits
to
propargite;
(
2)
the
Agency
determined
that
a
developmental
neurotoxicity
study
is
not
required;
(
3)
the
exposure
estimates
do
not
underestimate
the
potential
dietary
(
food
and
drinking
water)
exposures
for
infants
and
children
from
the
use
of
propargite;
and
(
4)
there
are
no
residential
uses
of
propargite.

d.
Endocrine
Disruptor
Effects
EPA
is
required
under
the
FFDCA,
as
amended
by
FQPA,
to
develop
a
screening
program
to
determine
whether
certain
substances
(
including
all
pesticide
active
and
other
ingredients)
"
may
have
an
effect
in
humans
that
is
similar
to
an
effect
produced
by
a
naturally
occurring
estrogen,
or
other
endocrine
effects
as
the
Administrator
may
designate."
Following
recommendations
of
its
Endocrine
Disruptor
Screening
and
Testing
Advisory
Committee
(
EDSTAC),
EPA
determined
that
there
was
scientific
basis
for
including,
as
part
of
the
program,
the
androgen
and
thyroid
hormone
systems,
in
addition
to
the
estrogen
hormone
system.
EPA
also
adopted
EDSTAC's
recommendation
that
EPA
include
evaluations
of
potential
effects
in
wildlife.
For
pesticides,
EPA
will
use
FIFRA
and,
to
the
extent
that
effects
in
wildlife
may
help
determine
whether
a
substance
may
have
an
effects
in
humans,
FFDCA
authority
to
require
the
wildlife
evaluations.
As
the
science
develops
and
resources
allows,
screening
of
additional
hormone
systems
may
be
added
to
the
Endocrine
Disruptor
Screening
Program
(
EDSP).

When
the
appropriate
screening
and/
or
testing
protocols
being
considered
under
the
EDSP
have
been
developed,
propargite
may
be
subject
to
additional
screening
and/
or
testing
to
better
characterize
effects
related
to
endocrine
disruption.

e.
Cumulative
Risks
56
The
Food
Quality
Protection
Act
(
FQPA)
requires
that,
when
considering
whether
to
establish,
modify,
or
revoke
a
tolerance,
the
Agency
consider
"
available
information"
concerning
the
cumulative
effects
of
a
particular
pesticide's
residues
and
"
other
substances
that
have
a
common
mechanism
of
toxicity."
Propargite
is
the
only
organosulfur
pesticide
with
registered
food
uses
and
therefore
the
only
organosulfur
chemical
that
is
subject
to
tolerance
assessment
under
the
FQPA.
Although
chemical
class
is
not
necessarily
synonymous
with
a
common
mechanism
of
toxicity,
structurally
similar
chemical
substances
do
frequently
exhibit
common
modes
of
toxicity
and
are
being
considered
together
by
EPA
for
purposes
of
cumulative
risk
assessment.
The
Agency
does
not
believe
that
propargite
shares
a
common
mechanism
of
toxicity
with
other
chemicals,
however.
Therefore,
propargite
is
not
subject
to
any
cumulative
risk
assessment
as
required
by
the
Food
Quality
Protection
Act
(
FQPA).

f.
Tolerances
Summary
A
summary
of
the
propargite
tolerance
reassessments
is
presented
in
Table
10.
In
the
assessment,
tolerances
for
residues
of
propargite
in/
on
plant
commodities
[
40
CFR
§
180.259]
are
presently
expressed
in
terms
of
the
parent
only.
Adequate
field
trials
are
available
pending
submission
of
required
storage
stability
data,
sample
storage
information,
or
required
label
amendments.

i.
Tolerances
Listed
Under
40
CFR
§
180.259(
a)

°
Citrus
pulp,
dried:
The
citrus
processing
study
did
not
detect
residue
concentration
in
dried
pulp,
indicating
that
the
current
40
ppm
tolerance
is
not
necessary
and
should
be
revoked.
°
Cottonseed:
Although
one
sample
of
cottonseed
showed
a
residue
of
0.11
ppm,
based
on
the
residue
data
for
other
samples
after
treatment
at
higher
rates,
the
Agency
considers
the
existing
0.1
ppm
tolerance
adequate
to
cover
the
current
label
use.
This
0.1
ppm
tolerance
is
also
in
harmony
with
the
Codex
level.
°
Oranges:
Data
on
oranges
indicate
that
residues
up
to
8.3
ppm
may
occur
from
registered
use
and
that
the
5
ppm
tolerance
is
inadequate.
This
tolerance
should
be
increased
to
10
ppm.
°
Poultry
meat
and
meat
byproducts:
These
tolerances
are
not
necessary
and
can
be
revoked;
propargite
was
absent
from
muscle
and
liver
in
the
metabolism
study
and
<
LOQ
in
a
10x
feeding
study.
°
Sorghum
grain:
The
residue
data
show
maximum
propargite
residues
were
as
high
as
3.8
ppm,
supporting
a
reduction
in
the
current
10
ppm
tolerance
to
a
new
tolerance
of
5
ppm.
°
All
other
tolerances
for
propargite
in
40
CFR
§
180.259(

For
all
other
crops
the

support
the
established

revoked
the
following
tolerances
effective
October
19,
1999;

1999].
Uses
of
propargite
on
these
crops
have
been
canceled
for
over
3
years.
Previous
rulemaking
also
revoked
the
tolerances
for
dried
apple
pomace,
dried

because
these
are
no
longer
considered
significant

ii.
Tolerances
to
be
Proposed
Under
40
CFR
§
180.259(
a)

°
Aspirated
Grain
Fractions
of
Field
Corn:
The
available
data
indicate
that
residues
of
propargite
concentrated
in
the
aspirated
grain
fractions
of
field
corn
but
do
not
concentrate
in
the
aspirated
grain
fractions
of
sorghum.
A
tolerance
for
aspirated
grain
fractions
must
be
proposed
at
0.4
ppm.
°
Cotton
Gin
Byproducts:
A
tolerance
for
residues
in/
on
cotton
gin
byproducts
is
required.
Additional
field
trials
are
needed
on
cotton
to
determine
a
tolerance
for
propargite
residues
in/
on
cotton
gin
byproducts.
°
Orange
oil:
Propargite
residues
concentrated
7x
in
orange
oil.
Based
upon
this
observed
concentration
and
Highest
Average
Field
Trial
(
HAFT)
residues
of
4
ppm
in
oranges,
a
tolerance
of
30
ppm
would
be
appropriate
for
residues
in
citrus
oil.

Although
residues
concentrated
in
raisins
by
1.7x,
this
factor
applied
to
the
HAFT
of
4.7
ppm
yields
a
concentration
in
raisins
of
8
ppm,
which
is
lower
than
the
10
ppm
tolerance
for
residues
in/
on
grapes.
Therefore,
a
tolerance
for
raisins
is
not
required.

The
U.

tolerances
for

and
Codex
MRLs
are
identical
with
respect
to
the
residue
regulated;
both
are

Harmonization
with
the
Codex
tolerance
limit
in/
on
citrus
fruits,
nectarines,
and
milk
is
not
possible
at
this
time
because
data
indicate
the
need
for
different

The
U.
S.
tolerance
for
citrus
fruits
is
being
proposed
as
10
ppm
(
raise
from

while
the

The
U.

And
finally,

Residue
Analytical
Methods
Analytical
methods
available
for
enforcing
propargite
tolerances
include
Methods
II,
V,
and
VI
for
plant
commodities
and
Methods
III
and
IV
for
animal
commodities
in
PAM,
Volume
II
(
Sec.
180.259).
The
preferred
enforcement
analytical
method
for
plant
commodities
is
Method
V.
All
are
gas
liquid
chromatography
(
GLC)
methods
with
either
sulfur­
specific
microcoulometric
detection
(
Method
II),
microcoulometric
detection
(
Method
III),
or
flame
photometric
detection
(
Methods
IV,
V,
and
VI).
Limits
of
quantitation
are
0.08
(
milk)
and
0.1
ppm
(
plant
and
animal
commodities).

GC/
FPD
methods
used
for
collecting
data
on
propargite
per
se
in
plant
and
animal
matrices
are
adequate
and
have
been
successfully
radiovalidated
using
samples
from
metabolism
studies.
However,
the
extraction
solvents
used
in
these
methods
are
not
the
same
as
those
employed
in
the
PAM
II
methods.
Radiovalidations
should
be
conducted
using
the
extraction
solvents
in
the
preferred
PAM
II
plant
and
animal
enforcement
methods,
or
other
methods
should
be
proposed
as
enforcement
methods.
For
other
methods
to
be
enforcement
methods,
independent
laboratory
method
validations
and
EPA
method
validations
would
be
needed.

The
GC/
FPD
data
collection
methods
that
are
based
on
the
PAM
II
methods
are
sensitive
to
0.05
ppm.
If
these
methods
were
tested
and
approved
for
enforcement
purposes,
numerous
tolerances
currently
set
at
the
0.1
ppm
LOQ
for
the
PAM
methods
could
be
lowered
to
0.05
ppm.
61
This
should
be
considered
only
after
detailed
scientific
review
by
the
Agency
of
the
residue
data..

Methods
have
been
submitted
for
enforcement
of
tolerances
for
residues
in
dried
tea
leaves.
The
Agency
has
determined
that
the
method
must
be
modified
to
include
Soxhlet
extraction.

D.
Regulatory
Rationale
The
following
is
a
summary
of
the
rationale
for
managing
risks
associated
with
the
current
use
of
propargite.
Where
labeling
revisions
are
warranted,
specific
language
is
set
forth
in
the
summary
tables
of
Section

of
this

Human
Health
Risk
Management
a.
Dietary
(
Food)
Risk
Mitigation
A
refined
Tier
3
dietary
risk
assessment
using
the
Dietary
Exposure
Evaluation
Model
(
DEEMTM)
was
completed
for
acute,
chronic
(
non­
cancer),
and
chronic
(
cancer)
food
exposure.
The
DEEMTM
analysis
evaluated
the
individual
food
consumption
as
reported
by
respondents
in
the
USDA
1989­
91
Continuing
Surveys
for
Food
Intake
by
Individuals
(
CSFII)
and
accumulated
exposure
to
the
chemical
for
each
commodity.
For
all
analyses,
anticipated
residues
and
percent
of
crop
treated
data
were
used.

i.
Acute
Dietary
(
Food)

Based
on
estimates
for
acute
exposure
to
propargite,
the
percentage
of
the
acute
Population
Adjusted
Doses
utilized
is
2
percent
for
females
13
­
50,
the
only
sub­
population
for
which
an
acute
endpoint
was
identified.
Therefore,
the
acute
dietary
(
food)
risk
estimate
for
propargite
is
not
of
concern,
and
no
mitigation
measures
are
needed.
62
ii.
Chronic
Dietary
(
Food)

The
chronic
dietary
analysis
utilized
USDA
Pesticide
Data
Program
(
PDP)
monitoring
data,
field
trial
data,
calculated
livestock
anticipated
residues,
and
percent
crop
treated
information.
Based
on
that
analysis,
the
percentage
of
cPAD
utilized
is
expected
to
be
less
than
1
percent
for
the
U.
S.
population
and
all
subpopulations.
Therefore,
the
chronic
dietary
(
food)
risk
estimate
is
also
not
of
concern,
and
no
mitigation
measures
are
needed.

iii.
Chronic
Cancer
Dietary
(
Food)

A
cancer
dietary
exposure
and
risk
analysis
was
performed
based
upon
revised
cancer
Q
1
*
of
0.033
(
mg/

day)
­
1
derived
from
a
2­
year
cancer
bioassay
on
rats
and
upon
Agency
analyses
anticipated
residues
of
propargite
in
food.
Based
on
that
analysis,
which
yielded
a
cancer
risk
of
1.8
x
10­
7,
the
Agency
has
concluded
that
the
cancer
dietary
risk
from
food
alone
is
not
of
concern,
and
that
no
mitigation
measures
are
needed
to
address
the
cancer
food
risk.

iv.
Drinking
Water
The
Agency
has
determined
that
there
are
no
acute
or
chronic
(
non­
cancer)
drinking
water
concerns
(
see
Section
III.
A.
3).
However,
the
Agency
risk
assessment
shows
potential
dietary
cancer
risks
of
concern
for
drinking
water
derived
from
surface
waters.
This
assessment
was
based
on
modeling
simulations
and
United
States
Geological
Survey
("
USGS")
monitoring
data.
The
modeling
simulations
predict
that
propargite
residues
in
surface
waters
have
a
20­
year
mean
concentration
of
4.8
ppb,
and
can
be
as
high
as
34
ppb.
The
annual
mean
concentrations
detected
at
the
USGS
monitoring
sites
ranged
from
0.3ppb
to
1.24
ppb.
The
cancer
DWLOC
is
0.71.

As
described
previously,
EPA
believes
that,
in
the
case
of
propargite,
the
modeling
simulations
and
monitoring
data
over­
estimate
the
actual
exposures
through
drinking
water.
In
the
modeling
simulations,
for
example,
the
model
input
variables
assumed
maximum
use
rates
and
frequencies
for
the
highest
use
crop.
Data
obtained
from
the
State
of
California,
where
about
75
percent
of
all
domestic
propargite
is
used,
indicate,
however,
that
typical
use
rates
are
significantly
below
maximum
use
rates.
In
fact,
the
California
data
indicate
that
the
maximum
use
rate
is
utilized
in
fewer
than
5
percent
of
all
applications.
This
figure
is
consistent
with
information
provided
to
EPA
from
several
grower
groups
indicating
that
propargite,
because
of
its
efficacy
against
adult
mites,
is
frequently
used
as
a
spot­
treatment
on
an
as­
needed
basis.
Similarly,
in
the
case
of
propargite,
the
Agency
believes
that
the
model
simulations
are
conservative
because
they
do
not
account
for
the
effect
of
water
treatment
processes.
Conventional
water
treatment
(
coagulation­
flocculationsedimentation
will
be
effective
in
removing
propargite
because
test
data
verifies
that
propargite
has
a
high
affinity
to
bind
with
soil
particles.

Regarding
the
USGS
monitoring
data,
which
measured
annual
mean
concentrations
of
propargite
in
the
San
Joaquin,
California
watershed
at
0.3
ppb
and
1.24
ppb
in
1992
and
1993,
respectively,
it
is
critical
to
note
that
these
data
were
developed
to
assess
ambient
surface
water
levels
of
pesticides
rather
than
drinking
water
exposures.
As
such,
the
data
does
not
account
for
such
factors
as
distance
between
sampling
locations
and
public
drinking
water
uptakes,
or
pesticide
63
removal
by
water
treatment
processes.
In
the
case
of
Oristimba
Creek,
the
propargite
concentrations
in
that
location
measured
20
ppb
on
one
occasion
during
the
2­
year
study.
However,
the
monitoring
station
on
that
creek
is
located
23
to
30
miles
upstream
of
the
two
nearest
drinking
water
intakes,
and
the
water
from
that
creek
empties
into
the
much
larger
San
Joaquin
river
shortly
after
the
monitoring
site.
If
the
values
from
that
one
creek
are
omitted
from
the
data
set,
the
time
weighted
average
would
be
.02
ppb,
a
value
below
the
cancer
DWLOC.

Because
propargite
has
a
strong
affinity
to
bind
to
soil,
it
is
likely
that
a
significant
portion
of
the
residues
in
surface
water
are
the
result
of
direct
spray
drift
rather
than
run­
off
from
soil.
Therefore,
reducing
spray
drift
is
likely
to
produce
a
significant
risk
reduction
in
propargite
resides
in
surface
water.
The
registrant
has
agreed
to
add
buffer
zones
(
no
application
of
propargite
by
ground
within
50
feet
or
by
air
within
75
feet
of
aquatic
areas)
and
spray
drift
requirements
to
the
label
to
minimize
propargite
runoff
into
surface
waters.

The
registrant
has
also
agreed
to
decrease
the
maximum
seasonal
application
and
frequencies
for
several
crops
(
beans
(
dry),
citrus,
corn,
cotton,
mint,
walnuts),
and
increase
spray
intervals
for
several
crops
from
7
to
21
days
(
28
days
for
citrus).
See
Table
11
for
new
seasonal
maximum
rates,
and
see
Table
12
for
new
spray
intervals.
These
measures
will
reduce
environmental
loading
of
propargite.
The
registrant
has
further
agreed
to
conduct
a
confirmatory
monitoring
study
to
ensure
that
actual
drinking
water
exposures
are
below
the
Agency's
level
of
concern.
That
study
will
institute
a
3­
year
sampling
regimen
designed
to
measure
concentrations
of
propargite
residues
in
surface
drinking
water
supplies
under
highly
vulnerable
conditions.

Aggregate
Risk
Mitigation
(
acute
and
chronic)

Because
there
are
no
residential
uses
of
propargite,
the
aggregate
risks
are
limited
to
dietary
(
food
and
water)
exposure.
The
risks
from
those
combined
exposures
are
discussed
above
in
the
preceding
section.
65
b.
Occupational
Risk
Mitigation
As
discussed
in
Chapter
III,
EPA
combines
chemical­
specific
studies
with
similar
surrogate
data
from
the
Pesticide
Handlers
Exposure
Database
("
PHED")
to
assess
handler
exposures
for
regulatory
actions.
In
addition,
the
exposure
estimates
from
PHED
are
used
to
assess
exposure
where
no
chemical
specific
data
are
available.
The
handler
exposure
assessments
encompass
all
of
the
major
uses
of
propargite
throughout
the
country.
Because
it
is
difficult
to
assess
"
typical"
agricultural
uses,
an
assessment
has
been
developed
that
is
believed
to
be
realistic
and
yet
provides
a
reasonable
certainty
that
the
exposures
are
not
underestimated.
For
example,
for
handlers,
the
assessment
assumes
that
handlers
are
exposed
to
the
maximum
concentrations
of
propargite,
for
the
highest
estimated
acreage,
for
8
hours
per
day
for
14
days
per
year.
Similarly,
for
post­
application
workers,
exposure
values
are
calculated
assuming
that
fields
are
100%
treated
at
maximum
allowable
rates,
and
that
workers
work
exclusively
in
those
treated
field
for
8
hours/
day,
for
30
days/
year.
The
cancer
post­
application
assessment
assumes
that
same
exposure
over
a
35­
year
period.
Also,
no
allowance
is
made
for
environmental
degradation
of
propargite,
further
ensuring
that
risks
are
not
likely
to
be
under­
estimated.

i.
Handler
Exposure
Handler
exposure
assessments
are
completed
by
EPA
using
a
baseline
exposure
scenario
and,
if
required,
increasing
levels
of
mitigation
(
PPE
and
engineering
controls)
to
achieve
a
margin
of
exposure
(
MOE)
of
100
or
greater
for
dermal
exposure
and
1,000
or
greater
for
inhalation
exposure.
For
non­
dietary
cancer
risks,
the
Agency
seeks
to
reduce
individual
risks
to
the
greatest
extent
feasible;
risks
greater
than
1
x
10­
6
are
of
concern.
The
Agency
typically
will
not
accept
risks
greater
than
1
x
10­
4.
For
risks
between
10­
6
and
10­
4,
EPA
carefully
evaluates
exposure
scenarios
to
seek
ways
to
reduce
the
cancer
risks
to
the
greatest
extent
feasible,
preferably
a
risk
less
than
1
x
10­
6.

To
mitigate
risks
to
mixers,
loaders,
and
applicators
from
propargite,
the
following
measures
have
been
agreed
to
by
the
Registrant:

°
To
address
the
risk
from
mixing
and
loading
liquids
for
aerial
application
of
propargite
to
corn
and
cotton
(
scenario
1a
in
table
8),
a
closed
mixing
loading
system
will
be
necessary.
°
To
protect
applicators
in
fixed­
wing
aircraft
(
scenario
3),
enclosed
cockpits
will
be
required.
°
To
address
the
risk
from
mixing
and
loading
wettable
powders
(
scenario
2)
water
soluble
packaging
is
necessary.
°
To
address
the
risk
from
airblast
spray
applications
(
scenario
5)
enclosed
cabs
(
that
provide
dermal
protection)
will
be
required.
66
°
To
protect
against
risks
for
all
other
scenarios,
personal
protective
equipment
(
socks,
shoes,
long­
sleeved
shirts,
long
pants,
and
gloves
are
necessary
for
all
scenarios
[
except
gloves
are
not
necessary
for
flagging
during
aerial
application
(
scenario
7).

In
addition,
as
a
Toxicity
Category
1
pesticide
that
is
corrosive
to
both
the
eye
and
skin
(
MRID
##
42857004
and
42857005),
propargite
end­
use
products
meet
the
restricted
use
criteria
under
40
CFR
152.170(
2)(
v)
and
(
vi).
As
such,
EPA
will
reclassify
propargite
as
a
restricted
use
pesticide
(
RUP).

For
most
worker
exposure
scenarios,
these
protections
provide
estimated
dermal/
inhalation
MOEs
equal
to
or
greater
than
the
100/
1000
MOE
target
values
described
above.
The
exception
is
mixing
and
loading
at
the
maximum
application
rate
for
aerial
application
on
corn.
While
the
registrant
has
agreed
to
the
maximum
protection
feasible
for
this
scenario,
which
is
requiring
closed
mixing
and
loading
systems,
the
MOE
achieved
is
only
80.
However,
because
the
MOE
is
based
on
the
conservative
assumptions
that
workers
would
be
mixing
and
loading
for
the
maximum
rate
for
the
maximum
acres
treated,
the
Agency
believes
workers
are
adequately
protected
for
this
scenario.
Although
the
estimated
cancer
risks
for
some
of
the
scenarios
are
slightly
above
the
1
x
10­
6
target
value,
the
Agency
is
confident
that,
with
the
above­
described
conservative
assumptions
built
into
its
exposure
models,
the
identified
mitigation
measures
provide
an
acceptable
level
of
protection.

ii.
Post­
application
Exposure
EPA
completes
exposure
assessments
on
post­
application
workers
for
various
crops
and
activities
at
intervals
following
the
application
until
risk
falls
below
a
target
level.
For
propargite,
the
target
level
for
dermal
risk
concerns
is
an
MOE
of
100;
for
inhalation
risk
concerns,
it
is
an
MOE
of
1000;
and
for
cancer,
the
target
risk
is
1
x
10­
6.
For
cancer
risks
between
1
x10
­
4
and
1
x
10­
6,
the
Agency
strives
for
risk
reduction
with
mitigation
measures
where
feasible.

In
order
to
determine
the
REI
for
a
crop,
EPA
calculates
the
number
of
days
that
must
elapse
after
pesticide
application
until
residues
dissipate
and
risk
to
a
worker
falls
below
the
target
risk
estimate
(
usually
expressed
as
an
MOE).
The
Agency
also
estimates
cancer
risk
at
that
target
interval.
In
addition,
occupational
risks
are
regulated
under
the
FIFRA
section
3(
c)(
5)
standard
­
"
without
unreasonable
adverse
effects
on
the
environment"
­
which
means
that
both
risks
and
benefits
must
be
considered
in
making
a
risk
management
decision.
This
standard
may
be
met
at
a
level
below
the
target
MOE
when
there
are
significant
benefits
associated
with
a
specific
activity.
As
the
worker
exposure
database
has
improved,
risk
assessments
are
now
conducted
for
a
variety
of
postapplication
activities
based
on
the
level
of
exposure
for
each
worker
activity
(
see
table
9,
"
Occupational
Postapplication
Risk
from
Propargite:
Days
After
Treatment
at
Which
the
MOE
is
$
100").
For
a
specific
crop/
pesticide
combination,
the
duration
required
to
achieve
the
target
MOE
can
vary
depending
on
the
activity
assessed.
In
general,
EPA
prefers
to
set
a
single
REI
for
all
activities
related
to
a
crop
or
crop
group
67
without
additional
activity­
based
labeling.
This
approach
is
favored
because
handlers
and
workers
are
more
likely
to
understand
and
comply
with
simpler
labels.
Also,
permitting
activity­
based
entry
for
one
crop
could
cause
confusion
and
compromise
the
effectiveness
of
the
WPS.
However,
when
the
consideration
of
risks
and
benefits
indicate
that
a
simple
REI
is
unworkable,
EPA
may
consider
either
setting
an
REI
with
early
entry
exceptions
for
one
or
more
critical
tasks
or
establishing
a
entry
prohibition
for
a
specific
task
after
the
REI
has
expired.
For
most
propargite
uses,
a
single
REI
is
being
proposed
because
no
critical
use
was
identified
that
warrants
the
use
of
an
exception
or
prohibition.
During
the
60­
day
comment
period
for
this
RED,
however,
EPA
will
accept
further
comments
from
growers
regarding
needs
for
additional
REI
exceptions
for
specific
activities,
and
will
add
such
exceptions
where
needed
if
there
are
adequate
MOEs
and/
or
benefits
associated
with
such
activities.

In
considering
worker
risks
and
benefits,
the
Agency
considered
the
timing
of
field
activities
that
are
critical
to
crop
production.
For
many
of
the
propargite
uses
discussed
below,
scouting
and
irrigation
are
critical
activities
in
crop
production,
and
these
activities
routinely
need
to
be
performed
soon
after
application.
In
evaluating
the
restricted
entry
intervals,
the
Agency
considered
the
exceptions
to
the
Worker
Protection
Standard
that
could
inform
the
decision.
EPA's
proposed
REIs
take
into
account
the
flexibility
already
provided
by
these
exceptions.
Scouting
is
a
handler
activity
under
the
WPS,
so
anyone
performing
this
activity
may
legally
enter
the
treated
field
during
the
REI
provided
they
use
the
handler
personal
protective
equipment
(
PPE)
specified
on
the
label.
In
addition,
if
the
scout
is
a
certified
crop
advisor
as
defined
in
the
WPS
(
40
CFR
170.204(
b)),
the
individual
can
determine
the
appropriate
PPE
to
be
used.
For
many
of
these
crops,
irrigation
equipment
is
not
routinely
moved
by
hand.
For
these
methods,
the
primary
activity
involves
entering
the
field
to
turn
the
watering
equipment
on
and
off.
This
activity
is
allowed
during
the
REI
under
the
no
contact
exception
to
WPS
(
40
CFR
170.112(
b)).
Should
irrigation
equipment
need
unexpected
repairs
during
the
REI,
WPS
allows
workers
to
enter
a
treated
field
provided
early
entry
PPE
is
used
(
40
CFR
170.112(
c)).
This
exception
also
usually
applies
to
mechanical
harvesting,
tree
shaking
for
nut
crops
in
enclosed
cabs,
and
often
applies
to
mowing.

For
all
post­
application
worker
exposure
scenarios
described
above,
the
proposed
REIs
provide
estimated
dermal/
inhalation
MOEs
equal
to
or
greater
than
the
100/
1000
MOE
target
values
described
above.
Although
the
estimated
cancer
risks
for
some
of
the
scenarios
are
slightly
above
the
1
x
10­
6
target
value
(
see
table
9),
the
Agency
believes
REIs
provide
an
acceptable
level
of
protection.
Many,
if
not
most,
workers
are
actually
not
at
risk
at
this
level
because
the
assessment
assumes
workers
perform
their
activities
for
8
hours
a
day,
30
days
a
year,
for
35
years
in
propargite
treated
crops
that
were
treated
at
the
maximum
rate.
The
probability
of
a
worker
meeting
all
these
conditions
is
small.
Further,
it
was
determined
to
be
infeasible
to
decrease
the
estimated
cancer
risk
by
increasing
the
REIs.
Even
large
increases
in
the
REI
produced
only
marginal
decreases
in
cancer
risk
when
calculated
over
a
35
year
lifetime
exposure.
This
is
because
of
the
persistence
of
propargite
residues
on
foliage.

To
address
potential
risks
to
post­
application
workers,
the
Agency
is
modifying
the
REIs
for
propargite
as
described
in
table
13
below.

2.
Environmental
Risk
Mitigation
a.
Avian
and
Mammalian
Risk
Mitigation
As
described
in
Chapter
III.,
chronic
toxicity
testing
on
bobwhite
quail
and
mallard
duck
indicates
that
propargite
has
adverse
reproductive
effects
on
avian
species.
Based
on
a
NOAEL
of
43.2
ppm
from
these
studies,
exposures
projected
in
the
Agency's
risk
assessment
are
expected
to
result
in
chronic
risk
concerns
for
birds
(
RQs
>
1.0).
These
chronic
risk
concerns
for
birds
are
predicted
by
the
risk
assessment
for
all
propargite
crop
applications
scenarios
with
rates
over
0.5
lb
ai/
acre.
For
mammals,
chronic
risk
concerns
for
herbivorous/
insectivorous
mammals
were
exceeded
for
all
five
modeled
single
and
multiple
application
crop
use
scenarios,
and
is
predicted
for
any
application
scenario
over
1.5
lb
ai/
A.
Acute
risk
concerns
were
approached
or
exceeded
by
predicted
exposures
to
multiple
applications
of
propargite
at
rates
of
3.0
to
4.5
lb
ai/
A.

Before
discussing
the
avian
and
mammalian
risk
management
aspects
of
this
reregistration
eligibility
decision,
it
should
be
noted
that
there
are
some
uncertainties
in
the
Agency's
terrestrial
risk
assessment
which
suggest
that
identified
risks
to
birds
and
mammals
may
be
lower
than
projected
in
this
specific
case.
First,
because
there
are
no
spray
intervals
on
the
current
product
labels,
the
risk
assessment
assumed
a
7­
day
spray
interval
in
its
exposure
model.
Given
propargite's
expected
high
persistence
on
foliage,
however,
it
is
unlikely
that
many
growers
actually
apply
it
with
such
frequency.
Moreover,
although
neither
EPA
nor
USDA
were
provided
with
specific
documentary
data,
both
71
Agencies
have
been
advised
by
numerous
grower
groups
that
a
significant
portion
of
propargite
applications
are
spot
applications
used
to
address
localized
mite
outbreaks,
whereas,
the
Agency's
model
assessed
exposures
from
full
field
applications.
Second,
as
described
in
the
drinking
water
section
of
this
chapter,
use
data
compiled
by
the
State
of
California,
where
75
percent
of
total
propargite
is
used,
indicate
that
propargite
is
frequently
applied
at
rates
well
below
the
maximum
permitted
use
concentrations
used
in
EPA's
modeling
scenarios.

In
light
of
these
uncertainties
surrounding
exposures
and
risks
to
avian
and
mammalian
species,
the
registrant
has
agreed
to
develop
further
data
to
better
characterize
the
risk
to
avian
species
likely
to
be
exposed
to
propargite.
The
registrant
has
also
agreed
to
a
number
of
measures
which
will
reduce
exposures
to
birds
and
mammals.
These
measures
are
as
follows:

°
Lowering
annual
application
amounts
for
mint,
walnuts,
citrus,
dry
beans,
cotton,
jojoba,
field
corn,
and
pop
corn
(
see
Table
11);
°
lowering
the
number
of
annual
applications
for
cotton
and
jojoba;
°
adding
spray
intervals
of
21
days
for
most
food
crops
(
28
days
for
citrus)
(
see
Table
12)
°
Adding
requirements
to
minimize
spray
drift;
°
Adding
label
language
advising
against
use
of
maximum
application
rates
unless
high
mite
infestations
exist.

Given
the
conservative
assumptions
used
in
the
propargite
model,
the
mitigation
outlined
above
and
the
considerable
benefits
(
discussed
below
in
Section
IV.
D.
2.
c.),
the
Agency
believes
that
no
further
action
is
required
at
this
time
to
address
avian
and
mammalian
risks
from
the
use
of
propargite.

b.
Aquatic
Risk
Mitigation
As
stated
in
Chapter
III.,
although
propargite
is
highly
toxic
to
all
fish
and
invertebrate
species
tested
(
96
hour
LC
50
values
for
7
aquatic
species
were
below
168
ug/
L),
the
RQs
calculated
from
EECs
derived
from
Tier
II
simulations
suggest
little
potential
for
acute
risk
to
fish
or
invertebrates.
However,
several
RQs
ranged
between
0.2
and
0.5
suggesting
that
exposure
in
small,
shallow
water
bodies
(
i.
e.,
those
not
represented
by
EPA's
standard
aquatic
risk
scenario)
could
result
in
adverse
effects
to
organisms
present.

All
of
the
risk
mitigation
measures
described
above
in
the
avian
and
mammalian
risk
mitigation
section
above
also
serve
to
mitigate
risks
to
aquatic
species.
In
addition
to
those
measures,
the
registrant
has
also
agreed
to
institute
no­
spray
zones
around
lakes
reservoirs,
rivers,
permanent
streams,
marshes
or
natural
ponds,
estuaries,
and
commercial
fish
farm
ponds.
The
buffer
zones
will
be
50
feet
for
ground
applications
and
75
feet
for
aerial
applications.
This
requirement
will
decrease
the
amount
of
propargite
reaching
surface
waters
directly
via
spray
applications
and
indirectly
via
field
runoff
of
precipitation
and
irrigation
water.
The
Agency's
current
models
are
unable
to
quantify
reductions
in
surface
water
concentrations
attributable
to
buffers
because
of
the
large
number
of
variables
that
affect
the
calculation
(
type
of
vegetation
in
the
buffer
area,
grade
and
topography
of
72
the
buffer
area,
soil
type,
etc.)
It
is
clear,
however,
that
some
reduction
in
runoff
concentrations
reaching
surface
waters
will
occur
.

c.
Benefits
In
making
a
reregistration
eligibility
determination
for
a
given
pesticide,
the
Agency
assesses
not
only
the
potential
risks
that
the
pesticide
may
present
to
human
health
or
the
environment,
but
also
the
benefits
which
accrue
from
its
use.
In
the
case
of
propargite,
the
Agency
identified
several
significant
benefits.
First,
as
shown
on
Table
14
below,
there
are
very
few
other
registered
miticides
on
the
market
which
have
the
efficacy
of
propargite,
and
those
alternatives
that
do
exist
are
either
not
approved
for
use
in
some
key
states,
or
are
significantly
more
expensive
to
apply.
Second,
several
of
the
miticides
which
are
potential
alternatives
to
propargite
have
been
reported
as
having
increasing
levels
of
resistance
over
the
last
few
years.
Mites,
some
species
of
which
undergo
20
life­
cycles
per
growing
season,
are
particularly
adept
at
developing
pesticide
resistance.
Third,
because
it
is
nontoxic
to
4
out
of
the
5
mite
predator
species
tested,
propargite
is
expected
to
be
an
important
component
of
several
Integrated
Pest
Management
(
IPM)
programs
currently
under
development
by
grower
groups.
Finally,
because
propargite
is
effective
against
adult
mites,
application
can
be
delayed
until
actual
infestations
are
detected.
Most
alternative
chemicals
need
to
be
applied
prophylactically
at
the
beginning
of
the
growing
season;
because
propargite
can
be
used
as
a
spot
treatment
on
an
asneeded
basis,
lower
overall
amounts
of
pesticides
are
frequently
used
on
mite­
prone
fields
propargite
is
the
miticide
selected.

Other
Label
Statements
In
order
to
be
eligible
for
reregistration,
various
use
and
safety
information
must
also
be
placed
on
the
labeling
of
all
end­
use
products
containing
propargite.
For
the
specific
labeling
statements,
refer
to
Section
V
of
this
document
a.
Endangered
Species
Statement
The
Agency
has
developed
the
Endangered
Species
Protection
Program
to
identify
pesticides
whose
use
may
cause
adverse
impacts
on
endangered
and
threatened
species,
and
to
implement
mitigation
measures
that
address
these
impacts.
The
Endangered
Species
Act
requires
federal
agencies
to
ensure
that
their
actions
are
not
likely
to
jeopardize
listed
species
or
adversely
modify
designated
critical
habitat.
To
analyze
the
potential
of
registered
pesticide
uses
to
affect
any
particular
species,
EPA
puts
basic
toxicity
and
exposure
data
developed
for
REDs
into
context
for
individual
listed
species
and
their
locations
by
evaluating
important
ecological
parameters,
pesticide
use
information,
the
geographic
relationship
between
specific
pesticides
uses
and
species
locations,
and
biological
requirements
and
behavioral
aspects
of
the
particular
species.
This
analysis
will
take
into
consideration
any
regulatory
changes
recommended
in
this
RED
that
are
being
implemented
at
that
time.
A
determination
that
there
is
a
likelihood
of
potential
impact
to
a
listed
species
may
result
in
limitations
on
use
of
the
pesticide,
other
measures
to
mitigate
any
potential

The
Endangered

Program
as
described
in
a
Federal
Register
notice
(
54
FR
27984­
28008,
July
3,
1989)
is
currently
being
implemented
on
an
interim
basis.
As
part
of
the
interim
program,
the
Agency
has
developed
County
Specific
Pamphlets
that
articulate
many
of
the
specific
measures
outlined
in
the
Biological
Opinions
issued
to
date.
These
Pamphlets
are
available
for
voluntary
use
by
pesticide
applicators,
on
EPA's
web
site
at
www.
EPA.
gov/
espp
.
A
final
Endangered
Species
Protection
Program,
which
may
be
altered
from
the
interim
program,
is
scheduled
to
be
proposed
for
public
comment
in
the
Federal
Register
before
the
end
of
2001.

Spray
Drift
Management
The
Agency
is
in
the
process
of
developing
more
appropriate
label
statements
for
spray,
and
dust
drift
control
to
ensure
that
public
health,
and
the
environment
is
protected
from
unreasonable
adverse
effects.
In
August
2001,
EPA
published
draft
guidance
for
label
statements
in
a
pesticide
registration
(
PR)
notice
("
Draft
PR
Notice
2001­
X"
http://
www.
epa.
gov/
PR_
Notices/#
2001).
A
Federal
Register
notice
was
published
on
August
22,
2001,
66
FR
44141
(
http://
www.
epa.
gov/
fedrgstr)
announcing
the
availability
of
this
draft
guidance
for
a
90­
day
public
comment
period.
After
receipt,
and
review
of
the
comments,
the
Agency
will
publish
final
guidance
in
a
PR
notice
for
registrants
to
use
when
labeling
their
products.
75
Until
EPA
decides
upon,
and
publishes
the
final
label
guidance
for
spray,
and
dust
drift,
the
registrant
for
propargite
has
agreed
to
add
the
following
spray
drift
related
language,
in
part
to
address
concerns
of
surface
water
runoff
of
propargite.

Do
not
allow
this
product
to
drift
off
target
site.

Do
not
apply
by
ground
within
50
ft.
or
by
air
within
75
ft.
of
lakes,
reservoirs,
rivers,
permanent
streams,
marshes
or
natural
ponds;
estuaries
and
commercial
fish
farm
ponds.

For
ground
applications
apply
the
coarsest
droplet
size
spectrum
that
provides
sufficient
coverage
and
mite
control.
Use
the
lowest
nozzle
height
that
provides
uniform
coverage.
Apply
only
when
wind
speeds
are
10
mph
or
less
when
measured
by
an
anemometer
outside
the
spray
area
on
the
upwind
side.

For
aerial
applications
apply
the
coarsest
droplet
size
spectrum
that
provides
sufficient
coverage
and
mite
control.
Apply
from
the
lowest
possible
height
that
provides
good
pest
control
and
flight
safety.
Use
the
shortest
boom
length
that
is
practical.
Apply
only
when
wind
speeds
are
10
mph
or
less
when
measured
by
an
anemometer
outside
the
spray
area
on
the
upwind
side.

Risk
of
exposure
to
sensitive
aquatic
areas
can
be
reduced
by
making
applications
when
the
wind
direction
is
away
from
the
aquatic
area.

Do
not
make
aerial
or
ground
applications
during
temperature
inversions.

1.
CONTENTS
OF
BIBLIOGRAPHY.
This
bibliography
contains
citations
of
all
studies
considered
relevant
by
EPA
in
arriving
at
the
positions
and
conclusions
stated
elsewhere
in
the
Reregistration
Eligibility
Document.
Primary
sources
for
studies
in
this
bibliography
have
been
the
body
of
data
submitted
to
EPA
and
its
predecessor
agencies
in
support
of
past
regulatory
decisions.
Selections
from
other
sources
including
the
published
literature,
in
those
instances
where
they
have
been
considered,
are
included.

2.
UNITS
OF
ENTRY.
The
unit
of
entry
in
this
bibliography
is
called
a
"
study."
In
the
case
of
published
materials,
this
corresponds
closely
to
an
article.
In
the
case
of
unpublished
materials
submitted
to
the
Agency,
the
Agency
has
sought
to
identify
documents
at
a
level
parallel
to
the
published
article
from
within
the
typically
larger
volumes
in
which
they
were
submitted.
The
resulting
"
studies"
generally
have
a
distinct
title
(
or
at
least
a
single
subject),
can
stand
alone
for
purposes
of
review
and
can
be
described
with
a
conventional
bibliographic
citation.
The
Agency
has
also
attempted
to
unite
basic
documents
and
commentaries
upon
them,
treating
them
as
a
single
study.

3.
IDENTIFICATION
OF
ENTRIES.
The
entries
in
this
bibliography
are
sorted
numerically
by
Master
Record
Identifier,
or
"
MRID"
number.
This
number
is
unique
to
the
citation,
and
should
be
used
whenever
a
specific
reference
is
required.
It
is
not
related
to
the
six­
digit
"
Accession
Number"
which
has
been
used
to
identify
volumes
of
submitted
studies
(
see
paragraph
4(
d)(
4)
below
for
further
explanation).
In
a
few
cases,
entries
added
to
the
bibliography
late
in
the
review
may
be
preceded
by
a
nine
character
temporary
identifier.
These
entries
are
listed
after
all
MRID
entries.
This
temporary
identifying
number
is
also
to
be
used
whenever
specific
reference
is
needed.

4.
FORM
OF
ENTRY.
In
addition
to
the
Master
Record
Identifier
(
MRID),
each
entry
consists
of
a
citation
containing
standard
elements
followed,
in
the
case
of
material
submitted
to
EPA,
by
a
description
of
the
earliest
known
submission.
Bibliographic
conventions
used
reflect
the
standard
of
the
American
National
Standards
Institute
(
ANSI),
expanded
to
provide
for
certain
special
needs.

a.
Author.
Whenever
the
author
could
confidently
be
identified,
the
Agency
has
chosen
to
show
a
personal
author.
When
no
individual
was
identified,
the
Agency
has
shown
an
identifiable
laboratory
or
testing
facility
as
the
author.
When
no
author
or
laboratory
could
be
identified,
the
Agency
has
shown
the
first
submitter
as
the
author.

b.
Document
date.
The
date
of
the
study
is
taken
directly
from
the
document.
When
the
date
is
followed
by
a
question
mark,
the
bibliographer
has
deduced
the
date
from
the
evidence
contained
in
the
document.
When
the
date
appears
as
(
1999),
the
Agency
was
unable
to
determine
or
estimate
the
date
of
the
document.
115
c.
Title.
In
some
cases,
it
has
been
necessary
for
the
Agency
bibliographers
to
create
or
enhance
a
document
title.
Any
such
editorial
insertions
are
contained
between
square
brackets.

d.
Trailing
parentheses.
For
studies
submitted
to
the
Agency
in
the
past,
the
trailing
parentheses
include
(
in
addition
to
any
self­
explanatory
text)
the
following
elements
describing
the
earliest
known
submission:

(
1)
Submission
date.
The
date
of
the
earliest
known
submission
appears
immediately
following
the
word
"
received."

(
2)
Administrative
number.
The
next
element
immediately
following
the
word
"
under"
is
the
registration
number,
experimental
use
permit
number,
petition
number,
or
other
administrative
number
associated
with
the
earliest
known
submission.

(
3)
Submitter.
The
third
element
is
the
submitter.
When
authorship
is
defaulted
to
the
submitter,
this
element
is
omitted.

(
4)
Volume
Identification
(
Accession
Numbers).
The
final
element
in
the
trailing
parentheses
identifies
the
EPA
accession
number
of
the
volume
in
which
the
original
submission
of
the
study
appears.
The
six­
digit
accession
number
follows
the
symbol
"
CDL,"
which
stands
for
"
Company
Data
Library."
This
accession
number
is
in
turn
followed
by
an
alphabetic
suffix
which
shows
the
relative
position
of
the
study
within
the
volume.

Appendix
G:
EPA
Batching
of
End
Use
Products
for
Meeting
Data
Requirements
for
Reregistration
In
an
effort
to
reduce
the
time,
resources
and
number
of
animals
needed
to
fulfill
the
acute
toxicity
data
requirements
for
reregistration
of
products
containing
propargite
as
the
primary
active
ingredient,
the
Agency
has
batched
products
which
can
be
considered
similar
for
purposes
of
acute
toxicity.
Factors
considered
in
the
sorting
process
include
each
product's
active
and
inert
ingredients
(
identity,
percent
composition
and
biological
activity),
type
of
formulation
(
e.
g.,
emulsifiable
concentrate,
aerosol,
wettable
powder,
granular,
etc.),
and
labeling
(
e.
g.,
signal
word,
use
classification,
precautionary
labeling,
etc.).
Note
the
Agency
is
not
describing
batched
products
as
"
substantially
similar"
since
some
products
with
in
a
batch
may
not
be
considered
chemically
similar
or
have
identical
use
patterns.

Using
available
information,
batching
has
been
accomplished
by
the
process
described
in
the
preceding
paragraph.
Notwithstanding
the
batching
process,
the
Agency
reserves
the
right
to
require,
at
any
time,
acute
toxicity
data
for
an
individual
product
should
need
arise.

Registrants
of
products
within
a
batch
may
choose
to
cooperatively
generate,
submit
or
cite
a
single
battery
of
six
acute
toxicological
studies
to
represent
all
the
products
within
that
batch.
It
is
the
registrants'
option
to
participate
in
the
process
with
all
other
registrants,
only
some
of
the
other
registrants,
or
only
their
own
products
within
in
a
batch,
or
to
generate
all
the
required
acute
toxicological
studies
for
each
of
their
own
products.
If
the
registrant
chooses
to
generate
the
data
for
a
batch,
he/
she
must
use
one
of
the
products
within
the
batch
as
the
test
material.
If
the
registrant
chooses
to
rely
upon
previously
submitted
acute
toxicity
data,
he/
she
may
do
so
provided
that
the
data
base
is
complete
and
valid
by
to­
days
standards
(
see
acceptance
criteria
attached),
the
formulation
tested
is
considered
by
EPA
to
be
similar
for
acute
toxicity,
and
the
formulation
has
not
been
significantly
altered
since
submission
and
acceptance
of
the
acute
toxicity
data.
Regardless
of
whether
new
data
is
generated
or
existing
data
is
referenced,
the
registrants
must
clearly
identify
the
test
material
by
EPA
Registration
Number.
If
more
than
one
confidential
statement
of
formula
(
CSF)
exists
for
a
product,
the
registrant
must
indicate
the
formulation
actually
tested
by
identifying
the
corresponding
CSF.

In
deciding
how
to
meet
the
product
specific
data
requirements,
registrants
must
follow
the
directions
given
in
the
Data
Call­
In
Notice
and
its
attachments
appended
to
the
RED.
The
DCI
Notice
contains
two
response
forms
which
are
to
be
completed
and
submitted
to
the
Agency
within
90
days
of
receipt.
The
first
form,
"
Data
Call­
in
Response,
"
asks
whether
the
registrant
will
meet
the
data
requirements
for
each
product.
The
second
form,
"
Requirements
Status
and
Registrant's
Response,"
lists
the
product
specific
data
required
for
each
product,
including
the
standard
six
acute
toxicity
tests.
A
registrant
who
wishes
to
participate
in
a
batch
must
decide
whether
he/
she
will
provide
the
data
or
depend
on
someone
else
to
do
so.
If
the
registrant
supplies
the
data
to
support
a
batch
of
products,
he/
she
must
select
the
one
of
the
following
options:
Developing
data
(
Option
1),
Submitting
an
existing
Study
(
Option
4),
Upgrading
an
existing
Study
(
Option
5),
or
Citing
an
Existing
Study
(
Option
).
If
a
registrant
depends
on
another's
data,
he/
she
must
choose
among:
Cost
sharing
(
Option
2),
Offers
to
Cost
Share
(
Option
3)
or
Citing
an
Existing
Study
(
Option
6).
If
a
registrant
does
not
want
to
participate
in
a
batch,
the
choices
are
Options
1,
4,
5
or
6.
However,
a
registrant
should
know
that
choosing
not
to
participate
in
a
batch
does
not
preclude
other
registrants
in
the
batch
from
citing
his/
her
studies
and
offering
to
cost
share
(
Option
3)
those
studies.
