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
assessments
for
the
antimicrobial,
Para­
Tertiaryamylphenol
(
4­
t­
amylphenol).
The
enclosed
Reregistration
Eligibility
Decision
(
RED)
document
was
approved
on
September
30,
2005.
Public
comments
and
additional
data
received
were
considered
in
this
decision.

Based
on
its
review,
EPA
is
now
publishing
its
Reregistration
Eligibility
Decision
(
RED)
and
risk
management
decision
for
4­
t­
amylphenol
and
its
associated
human
health
and
environmental
risks.
A
Notice
of
Availability
will
be
published
in
the
Federal
Register
announcing
the
publication
of
the
RED.

The
RED
and
supporting
risk
assessments
for
4­
t­
amylphenol
are
available
to
the
public
in
EPA's
Pesticide
Docket
OPP­
2005­
0181
at:
http://
www.
epa.

edockets.

The
4­
t­
amylphenol
RED
was
developed
through
EPA's
public
participation
process,
published
in
the
Federal
Register
on
July
20,
2005,
which
provides
opportunities
for
public
involvement
in
the
Agency's
pesticide
tolerance
reassessment
and
reregistration
programs.
Developed
in
partnership
with
USDA
and
with
input
from
EPA's
advisory
committees
and
others,
the
public
participation
process
encourages
robust
public
involvement
starting
early
and
continuing
throughout
the
pesticide
risk
assessment
and
risk
mitigation
decision
making
process.
The
public
participation
process
encompasses
full,
modified,
and
streamlined
versions
that
enable
the
Agency
to
tailor
the
level
of
review
to
the
level
of
refinement
of
the
risk
assessments,
as
well
as
to
the
amount
of
use,
risk,
public
concern,
and
complexity
associated
with
each
pesticide.
Using
the
public
participation
process,
EPA
is
attaining
its
strong
commitment
to
both
involve
the
public
and
meet
statutory
deadlines.

Please
note
that
the
4­
t­
amylphenol
risk
assessment
and
the
attached
RED
document
concern
only
this
particular
pesticide.
This
RED
presents
the
Agency's
conclusions
on
the
dietary,
drinking
water,
occupational
and
ecological
risks
posed
by
exposure
to
4­
t­
amylphenol
alone.
This
document
also
contains
both
generic
and
product­
specific
data
that
the
Agency
intends
to
require
in
Data
Call­
Ins
(
DCIs).
Note
that
DCIs,
with
all
pertinent
instructions,
will
be
sent
to
registrants
at
a
later
date.
Additionally,
for
product­
specific
DCIs,
the
first
set
of
required
responses
will
be
due
90
days
from
the
receipt
of
the
DCI
letter.
The
second
set
of
required
responses
will
be
due
eight
months
from
the
receipt
of
the
DCI
letter.

As
part
of
the
RED,
the
Agency
has
determined
that
4­
t­
amylphenol
will
be
eligible
for
reregistration
provided
that
all
the
conditions
identified
in
this
document
are
satisfied,
including
implementation
of
the
risk
mitigation
measures
outlined
in
Section
IV
of
the
document.
Sections
IV
and
V
of
this
RED
document
describe
labeling
amendments
for
end­
use
products
and
data
requirements
necessary
to
implement
these
mitigation
measures.
Instructions
for
registrants
on
submitting
the
revised
labeling
can
be
found
in
the
set
of
instructions
for
product­
specific
data
that
accompanies
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
4­
t­
amylphenol.
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.

If
you
have
questions
on
this
document
or
the
label
changes
necessary
for
reregistration,
please
contact
the
Chemical
Review
Manager,

Executive
Summary
The
Environmental
Protection
Agency
(
hereafter
referred
to
as
EPA
or
the
Agency)
has
completed
its
review
of
public
comments
on
the
human
health
and
environmental
risk
assessments
for
para­
tertiary­
amylphenol
(
4­
t­
amylphenol)
and
its
potassium
and
sodium
salt
and
is
issuing
its
risk
management
decision.
The
Agency
has
determined
4­
t­
amylphenol
and
its
potassium
and
sodium
salts
are
eligible
for
reregistration
provided
all
measures
outlined
in
this
document
are
implemented.
4­
t­
Amylphenol
is
a
member
of
the
phenolic
class
of
antimicrobials.
4­
t­
Amylphenol
is
an
active
ingredient
in
disinfectant,
food­
contact
sanitizer
and
deodorizer
products
used
in
agricultural,
food
handling,
commercial,
institutional,
industrial,
residential,
public
access,
and
medical
settings,
primarily
on
hard,
non­
porous
surfaces.
The
majority
of
the
products
are
virucidal,
fungicidal,
tuberculocidal
or
bactericidal.
Examples
of
registered
uses
for
4­
t­
amylphenol
include
application
to
hard
surfaces
(
e.
g.,
walls,
floors,
tables,
fixtures),
textiles
(
e.
g.,
clothing,
diapers,
mattresses,
bedding),
carpets,
medical
instruments,
and
agricultural
equipment.
Additionally,
there
are
registered
uses
for
fogging
in
occupational
settings
and
air
deodorization
in
both
occupational
and
residential
settings.

Overall
Risk
Summary
The
Agency's
human
heath
risk
assessment
indicates
no
risks
of
concern
for
dietary
or
drinking
water
exposures.
An
acute
dietary
risk
estimate
was
completed
for
females
13­
49
years
old,
the
only
population
subgroup
with
an
acute
toxicity
endpoint,
and
is
below
the
Agency's
level
of
concern.
Chronic
dietary
risk
estimates
were
provided
for
the
general
U.
S.
population
and
all
population
subgroups.
All
chronic
dietary
risk
estimates
are
below
the
Agency's
level
of
concern.

4­
t­
Amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters
based
on
its
use
patterns
and
fate
characteristics.
Thus,
a
drinking
water
assessment
was
not
conducted.
Therefore,
no
risk
mitigation
measures
are
required
to
address
4­
t­
amylphenol
exposure
from
drinking
water.

Residential
risks
from
handler
and
post­
application
exposure
were
calculated
for
shortand
intermediate­
term
dermal,
inhalation
and
incidental
oral
exposures.
All
exposure
and
risk
estimates
for
residential
handler
scenarios
are
below
the
Agency's
level
of
concern.
Risks
of
concern
have
been
identified
for
several
post­
application
exposure
scenarios
including
children's
dermal
exposure
to
treated
clothing
and
treated
diapers
and
children's
incidental
oral
exposure
to
treated
clothing.
The
Agency
believes
that
adding
clear
instructions
for
washing
and
rinsing
textile
items
will
result
in
the
adequate
removal
of
residues
from
the
treated
items
and
address
the
Agency's
concerns
for
this
scenario.
The
MOE
for
dermal
exposure
to
children
to
treated
surfaces
in
daycare
centers
slightly
exceeds
the
Agency's
level
of
concern
(
MOE
=
940
with
a
target
MOE
of
1,000).
However,
the
Agency
believes
actual
exposure
from
this
pathway
to
not
exceed
its
level
of
concern
when
taking
into
account
the
conservative
nature
of
the
risk
estimate
which
is
likely
to
overestimate
potential
exposures.
xvi
Aggregate
short
and
intermediate
term
risk
assessments
were
conducted
for
this
chemical
that
includes
incidental
oral
and
inhalation
risks
only.
Dermal
risks
are
not
included
in
the
aggregate
risk
estimates
because
they
have
a
different
toxicity
endpoint.
The
aggregate
oral
and
inhalation
risks
are
not
of
concern
for
adults,
as
the
total
aggregate
MOE
is
greater
than
the
target
of
3,000.
For
children,
the
aggregate
risk
estimates
are
also
above
the
target
MOE
of
3,000
and
thus
are
not
of
concern.
However,
incidental
oral
exposures
to
treated
textiles
are
not
included
in
the
aggregate
assessment
because
the
oral
MOE
is
already
of
concern.

For
the
occupational
handler
dermal
and
inhalation
risk
assessment,
the
short­
and
intermediate­
term
risks
calculated
at
baseline
exposure
(
no
gloves
and
no
respirators)
were
above
target
MOEs
for
all
scenarios.
For
most
of
the
occupational
scenarios,
postapplication
dermal
exposure
is
not
expected
to
occur
or
is
expected
to
be
negligible
based
on
the
application
rates
and
chemical
properties
of
the
chemical.
Postapplication/
bystander
inhalation
exposures,
however,
were
assessed
for
entry
into
a
building
after
a
fogging
application.
The
representative
building
selected
was
a
poultry
barn.
The
calculated
inhalation
MOEs
were
above
the
target
MOE
of
300
for
all
fogging
postapplication
scenarios
with
the
exception
of
the
scenario
for
8­
hr
exposure
to
the
product
with
a
2­
hr
reentry
interval
(
MOE
=
86).

There
is
a
concern
about
the
possibility
of
endocrine
disruption
in
fish,
since
4­
tamylphenol
is
considered
an
ecoestrogen.
However,
since
this
chemical
is
restricted
to
indoor
uses
only,
the
possibility
for
exposure
to
fish
to
4­
t­
amylphenol
would
be
limited.
The
limited
exposure
resulting
from
indoor
uses
of
4­
t­
amylphenol
and
its
salts
is
not
anticipated
to
cause
adverse
effects
to
terrestrial
or
aquatic
organisms.

Dietary
Exposure
Risk
An
acute
dietary
risk
assessment
was
conducted
for
4­
t­
amylphenol
indirect
food
uses.
Dietary
risk
estimates
are
provided
for
females
13­
49
years
old,
the
only
population
subgroup
for
which
an
endpoint
was
selected.
The
result
of
this
assessment
showed
the
risk
estimate
to
be
2.7%
of
the
aPAD
and
therefore
is
not
of
concern
A
chronic
dietary
risk
assessment
was
conducted
for
4­
t­
amylphenol
food
uses.
The
risk
analysis
assumes
daily
exposure
from
the
hard
surface
disinfection
of
counter
tops.
The
result
of
this
assessment
showed
the
risk
estimates
to
be
<
42%
of
the
cPAD
and
therefore
are
not
of
concern.

Drinking
Water
Risk
4­
t­
Amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters
based
on
its
use
patterns
and
fate
characteristics.
There
are
no
currently
registered
outdoor
uses
of
4­
t­
amylphenol
and
its
salts.
Further,
the
estimated
value
for
biodegradation
indicates
it
may
biodegrade
linearly
within
days
in
the
aquatic
environment,
although
ultimate
biodegradation
(
mineralization)
may
take
months.
It
also
is
volatile
based
on
its
vapor
pressure
of
0.00116
mmHg,
and
has
a
moderate
to
slight
mobility
in
soils
based
on
its
estimated
Koc
value
of
3799.
The
sodium
and
potassium
salts
of
4­
t­
amylphenol
also
are
slightly
to
moderately
mobile
in
xvii
soils,
and
are
estimated
to
biodegrade
within
days
to
weeks.
Because
of
the
possibility
of
biodegradation
in
water
and
soils
and
the
lack
of
outdoor
uses,
4­
t­
amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters.
Thus,
a
drinking
water
assessment
was
not
conducted.

Residential
Handler
Risk
For
residential
handlers
that
handle
products
containing
4­
t­
amylphenol
and
its
salts,
short­
term,
and
intermediate­
term
MOEs
were
above
the
target
MOEs
(
i.
e.,
 
>
1,000
for
dermal
and
>
3,000
for
inhalation)
for
all
scenarios
evaluated
and
thus,
do
not
exceed
the
Agency's
level
of
concern.

Residential
Post­
Application
Risk
Risks
of
concern
have
been
identified
for
several
post­
application
exposure
scenarios
including
children's
dermal
exposure
to
treated
clothing
and
treated
diapers
and
children's
incidental
oral
exposure
to
treated
clothing.
The
Agency
believes
that
adding
clear
instructions
for
washing
and
rinsing
textile
items
will
result
in
the
adequate
removal
of
residues
from
the
treated
items
and
address
the
Agency's
concerns
for
this
scenario.
The
MOE
for
dermal
exposure
to
children
to
treated
surfaces
in
daycare
centers
slightly
exceeds
the
Agency's
level
of
concern
(
MOE
=
940
with
a
target
MOE
of
1,000).
However,
the
Agency
believes
actual
exposure
from
this
pathway
to
not
exceed
its
level
of
concern
when
taking
into
account
the
conservative
nature
of
the
risk
estimate
which
is
likely
to
overestimate
potential
exposures.

Aggregate
Risk
Short­
and
intermediate­
term
aggregate
risks
are
considered
together
because
the
exposure
and
toxicity
endpoints
are
identical
for
incidental
oral
and
inhalation
residential
exposures
for
both
durations.
For
children,
the
short­
and
intermediate­
term
aggregate
assessment
includes
average
dietary
exposure
(
food)
and
estimated
incidental
oral
exposures
to
children
from
residential
uses
such
as
hard
surface
disinfection.
In
addition,
inhalation
exposure
from
post­
application
of
an
air
deodorizer
use
was
aggregated
with
the
oral
exposures
since
the
toxicity
endpoint
is
the
same.
For
adults,
the
aggregate
assessment
includes
dietary
(
oral)
and
residential
inhalation
exposures
from
wiping
a
hard
surface
disinfectant,
in
addition
to
post
application
inhalation
exposure
from
the
air
deodorizer.

Aggregate
oral
and
inhalation
risks
are
not
of
concern
for
adults,
as
the
total
aggregate
MOE
is
greater
than
the
target
of
3,000.
For
children,
the
aggregate
risk
estimates
are
also
above
the
target
MOE
of
3,000
and
thus
are
not
of
concern.
As
noted
previously,
incidental
oral
exposures
to
treated
textiles
are
not
included
in
the
aggregate
assessment
because
the
oral
MOE
is
already
of
concern.

A
dermal
aggregate
assessment
was
not
conducted
because
the
toxicity
effects
for
the
dermal
exposure
route
are
not
the
same
as
the
oral/
inhalation
exposure
route.
However,
short
xviii
and
intermediate
dermal
risks
are
already
of
concern
for
residents
for
the
treated
textile
and
diaper
use.

Occupational
Risk
To
assess
the
handler
risks,
the
Agency
used
surrogate
unit
exposure
data
from
both
the
proprietary
Chemical
Manufacturers
(
CMA)
antimicrobial
exposure
study
and
the
Pesticide
Handlers
Exposure
Database
(
PHED).
For
the
occupational
handler
dermal
and
inhalation
risk
assessment,
the
short­
and
intermediate­
term
risks
calculated
at
baseline
exposure
(
no
gloves
and
no
respirators)
were
above
target
MOEs
for
all
scenarios
(
i.
e.,
dermal
MOEs
>
100
and
inhalation
MOEs
were
>
300).
Note,
however,
that
high
pressure
spray
application
method
in
the
agricultural
use
site
category
was
assessed
using
gloved
data.

For
most
of
the
occupational
scenarios,
post­
application
dermal
exposure
is
not
expected
to
occur
and
it
is
expected
to
be
negligible
based
on
the
application
rates
and
chemical
properties
of
the
chemical.
However,
post­
application/
bystander
inhalation
exposures
were
assessed
for
entry
into
a
building
after
fogging
application.
The
representative
building
selected
was
a
poultry
barn.
The
Agency
used
MCCEM
(
Multi­
Chamber
Concentration
and
Exposure
Model)
to
estimate
post­
application/
bystander
exposures.
The
calculated
inhalation
MOEs
were
above
the
target
MOE
of
300
for
all
fogging
post­
application
scenarios
with
the
exception
of
the
scenario
for
8­
hour
exposure
to
the
product
with
a
2­
hour
re­
entry
interval
(
MOE
=
86).

The
Agency
does
not
believe
that
any
mitigation
is
necessary
to
address
the
postapplication
scenario
with
a
2­
hr
reentry
interval
at
this
time.
The
risk
estimate
was
calculated
using
the
Agency's
standard
assumptions
for
air
exchange
rates.
The
Agency
believes
that
in
the
case
of
animal
barns
and
facilities
this
assumption
in
very
conservative
given
the
relatively
high
air
exchange
rates
for
such
facilities.

Ecological
Risk
There
is
a
concern
about
the
possibility
of
endocrine
disruption
in
fish,
since
4­
tamylphenol
is
considered
an
ecoestrogen.
This
was
documented
in
several
studies
on
carp
(
Cyprimus
carpio).
However,
since
this
chemical
is
restricted
to
indoor
uses
only,
the
possibility
for
exposure
to
fish
to
4­
t­
amylphenol
would
be
limited.
The
limited
exposure
resulting
from
indoor
uses
of
4­
t­
amylphenol
and
its
salts
is
not
anticipated
to
cause
adverse
effects
to
terrestrial
or
aquatic
organisms.

Regulatory
Decision
The
Agency
has
completed
its
review
and
has
determined
that
the
data
are
sufficient
to
support
reregistration
of
all
supported
products
containing
4­
t­
amylphenol.
The
Agency
is
issuing
this
RED
for
4­
t­
amylphenol,
as
announced
in
a
Notice
of
Availability
published
in
the
Federal
Register.
This
RED
document
includes
guidance
and
time
frames
for
making
any
necessary
label
changes
for
products
containing
4­
t­
amylphenol.
xix
Summary
of
Mitigation
Measures
The
Agency
has
determined
that
4­
t­
amylphenol
and
its
salts
(
potassium
and
sodium)
are
eligible
for
reregistration
provided
the
mitigation
measures
described
in
this
document
and
the
label
changes
included
in
Table
13
in
Section
V
of
the
RED
are
implemented.

Residential
Risk
Mitigation
To
reduce
residential
exposure,
the
Agency
has
determined
that
the
following
mitigation
and
label
changes
for
specific
scenarios
are
appropriate
and
required
for
reregistration
eligibility:

­
Delete
all
diaper
uses
­
Delete
all
use
on
non­
laundered
textiles\
items
including
mattresses,
helmets,
headgear,
headphones,
facegear,
and
mouthpieces.
­
All
labels
with
laundered
textile
uses
must
have
directions
that
indicate
that
items
must
be
treated
prior
to
washing
and
rinsing.

I.
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
and
amended
again
by
the
Pesticide
Registration
Improvement
Act
of
2003
to
set
time
frames
for
the
issuance
of
Reregistration
Eligibility
Decisions.
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
(
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
or
not
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.
The
Agency
has
decided
that,
for
those
chemicals
that
have
tolerances
and
are
undergoing
reregistration,
the
tolerance
reassessment
will
be
initiated
through
this
reregistration
process.
The
Act
also
requires
that
by
2006,
EPA
must
review
all
tolerances
in
effect
on
the
day
before
the
date
of
the
enactment
of
the
FQPA.
FQPA
also
amends
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA)
to
require
a
safety
finding
in
tolerance
reassessment
based
on
factors
including
consideration
of
cumulative
effects
of
chemicals
with
a
common
mechanism
of
toxicity.
This
document
presents
the
Agency's
revised
human
health
and
ecological
risk
assessments;
and
the
Reregistration
Eligibility
Decision
(
RED)
for
4­
tertiary­
amylphenol
(
4­
t­
amylphenol),
and
salts
(
potassium
and
sodium).

4­
t­
Amylphenol
and
salts
are
active
ingredients
in
disinfectant
and
food­
contact
sanitizer
products
used
in
agricultural,
food
handling,
commercial/
institutional/
industrial,
residential,
public
access,
and
medical
settings
 
primarily
on
hard,
non­
porous
surfaces.
The
majority
of
the
products
are
virucidal,
fungicidal,
bactericidal,
pseudomonacidal,
or
staphylocidal.
Examples
of
registered
uses
for
4­
t­
amylphenol
and
salts
include
application
to
hard
surfaces
(
e.
g.,
walls,
floors,
tables,
and
fixtures),
textiles
(
e.
g.,
clothing,
diapers,
mattresses,
and
bedding),
carpets,
medical
instruments,
and
agricultural
equipment.
Additionally,
there
are
registered
uses
for
fogging
in
occupational
settings
and
air
deodorization
in
both
occupational
and
residential
settings.
Concentrations
of
4­
t­
amylphenol
and
salts
in
products
range
from
0.0027%
to
10%.
The
products
are
formulated
as
soluble
concentrates,
ready­
to­
use
liquid
solutions,
pressurized
sprays,
and
impregnated
wipes.

The
Agency
has
concluded
that
the
hazard
based
FQPA
safety
factor
should
be
retained
at
10X.
The
toxicology
data
base
is
not
complete
with
respect
to
assessing
the
increased
susceptibility
to
infants
and
children
as
required
by
FQPA
for
4­
t­
amylphenol.
The
rat
prenatal
developmental
study
showed
no
quantitative
evidence
of
increased
susceptibility
(
i.
e.,
developmental
NOAELs
/
LOAELs
were
higher
than
those
for
maternal
effects).
However,
there
was
qualitative
evidence
of
increased
susceptibility
as
the
fetal
effects
(
i.
e.,
skeletal
abnormalities,
decreased
body
weight
gain)
were
considered
to
be
more
severe
than
maternal
toxicity
(
reversible
clinical
signs).
In
addition,
there
is
an
absence
of
developmental
toxicity
data
in
the
rabbit,
and
an
absence
of
reproductive
toxicity
data.
Furthermore,
studies
in
the
open
2
literature
suggest
that
4­
t­
amylphenol
may
be
an
endocrine
disruptor.
It
increased
non­
pregnant
uterine
weight
in
rats
and
was
associated
with
elevated
blood
levels
of
billirubin
in
children
exposed
to
4­
t­
amylphenol
and
other
phenols
in
disinfectants.
These
studies,
while
not
indicative,
are
suggestive
of
a
basis
for
increased
concern
for
reproductive
and/
or
developmental
effects
due
to
exposure
to
4­
t­
amylphenol.

Risks
summarized
in
this
document
are
those
that
result
only
from
the
use
of
the
active
ingredients
4­
t­
amyphenol
and
its
salts
(
potassium
and
sodium).
The
Food
Quality
Protection
Act
(
FQPA)
requires
that
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
reason
for
consideration
of
other
substances
is
due
to
the
possibility
that
lowlevel
exposures
to
multiple
chemical
substances
that
cause
a
common
toxic
effect
by
a
common
toxic
mechanism
could
lead
to
the
same
adverse
health
effect
that
would
occur
at
a
higher
level
of
exposure
to
any
of
the
substances
individually.
Unlike
other
pesticides
for
which
EPA
has
followed
a
cumulative
risk
approach
based
on
a
common
mechanism
of
toxicity,
EPA
has
not
made
a
common
mechanism
of
toxicity
finding
for
4­
t­
amyphenol
and
its
salts
(
potassium
and
sodium)
and
any
other
substances.
4­
t­
Amyphenol
and
it
salts
(
potassium
and
sodium)
do
not
appear
to
produce
a
toxic
metabolite
produced
by
other
substances.
For
the
purposes
of
this
action,
therefore,
EPA
has
not
assumed
that
4­
t­
amyphenol
and
it
salts
(
potassium
and
sodium)
has
a
common
mechanism
of
toxicity
with
other
substances.

The
Agency
has
reviewed
all
toxicity
studies
submitted
for
4­
t­
amylphenol
and
has
determined
that
the
toxicological
database
is
sufficient
for
reregistration.
Major
features
of
the
toxicology
profile
are
presented
below.
The
toxicology
database
for
4­
t­
amylphenol,
in
terms
of
guideline
studies,
is
largely
incomplete.
4­
t­
amylphenol
appears
to
be
a
primary
dermal
and
eye
irritant
(
Category
I),
and
it
may
be
in
Category
III
for
acute
oral
dermal
studies,
according
to
data
from
the
open
literature,
and
two
registrant
submitted
studies.
However,
four
acceptable
guideline
acute
studies
are
not
available,
and
the
literature
data
protocols
were
inadequate.

In

4­

amylphenol
produced
clinical
signs
along
with
decreased
food
consumption
and
body
weight
in
a
developmental
toxicity
study,
but
not
systemic
effects
in
a
13­
week
dermal
study.
The
structural
abnormalities
and
developmental
delays
that
occurred
in
the
developmental
study
occurred
at
higher
dose
levels
than
the
maternal
effects,
suggesting
that
increased
quantitative
susceptibility
concerns
are
not
warranted.
However,
the
minimal
maternal
effects
(
reversible
clinical
signs)
seen
in
the
presence
of
developmental
effects
increases
concern
for
qualitative
susceptibility.

Available
data
suggest
that
4­
t­
amylphenol
has
endocrine
disrupter
capabilities
(
uterotrophic
and
estrogenic
effects)
and
increased
billirubin
production
in
babies.
When
taken
with
the
lack
of
available
developmental
and
reproductive
toxicity
data,
concerns
for
FQPA
issues
are
heightened.

General
Toxicity
Observations
Dietary
The
acute
RfD
is
0.67
mg/
kg/
day
for
females
(
13­
50
years),
based
on
adverse
developmental
effects
(
skeletal
effects
and
decreased
fetal
body
weight)
at
500
mg/
kg/
day
in
a
rat
developmental
study.
The
chronic
RfD
is
0.17
mg/
kg/
day
based
on
clinical
signs
of
toxicity
and
decreased
body
weight
and
food
consumption
at
200
mg/
kg/
day
in
a
rat
developmental
study.
An
uncertainty
factor
of
300
(
10X
for
interspecies
extrapolation,
10X
for
intraspecies
variability,
and
3X
for
database
uncertainties)
was
applied
to
the
NOAEL
to
obtain
the
acute
and
chronic
RfDs.
A
database
uncertainty
factor
of
3x
is
applied
to
non­
occupational
risk
assessments
for
4­
t­
amylphenol,
due
to
the
number
and
significance
of
the
data
gaps
including
lack
of
repeated
oral
toxicity
studies.
An
additional
Food
Quality
Protection
Factor
(
FQPA)
safety
factor
is
applied,
which
is
discussed
below.
8
Incidental
Oral
The
short­
and
intermediate­
term
incidental
oral
NOAEL
is
50
mg/
kg/
day
from
a
rat
oral
developmental
toxicity
study
that
noted
clinical
signs,
decreases
in
body
weight
and
body
weight
gain,
coupled
with
decreased
food
consumption
at
200
mg/
kg/
day.
The
target
margin
of
exposure
(
MOE)
is
3,000
(
includes
10X
FQPA
factor).

Short­
and
Intermediate­
term
Dermal
The
short­
and
intermediate­
term
dermal
NOAEL
is
25
mg/
kg/
day,
which
is
based
on
the
lack
of
systemic
effects
identified
up
to
and
including
a
dose
of
25
mg/
kg/
day
in
a
rat
subchronic
dermal
toxicity
study.
Uncertainty
factors
or
"
target"
margins
of
exposure
(
MOE)
for
4­
tamylphenol
dermal
exposures
are
100
for
occupational
scenarios
and
1,000
for
residential
scenario
(
includes
10X
FQPA
factor).

Short­,
Intermediate­
and
Long­
term
Inhalation
The
short­,
intermediate­
and
long­
term
inhalation
NOAEL
is
50
mg/
kg/
day
from
a
rat
oral
developmental
toxicity
study
that
noted
clinical
signs,
decreases
in
body
weight
and
body
weight
gain,
coupled
with
decreased
food
consumption
at
200
mg/
kg/
day.
In
the
absence
of
data,
it
was
conservatively
assumed
that
inhalation
absorption
is
equivalent
to
oral
absorption
(
i.
e.,
100%).
For
inhalation
exposures,
the
uncertainty
factors
are
300
for
occupational
scenarios
and
3,000
for
residential
scenarios
(
includes
10X
FQPA
factor).
An
additional
3X
database
uncertainty
factor
was
applied
due
to
the
absence
of
inhalation
toxicity
data,
and
studies
that
address
the
sensitivity
of
infants
and
children.
The
3,000
MOE
represents
the
maximum
uncertainty
that
can
be
applied
under
Agency
guidelines
and
applies
to
residential
exposures.

Carcinogenicity
Classification
There
are
no
lifetime
carcinogenicity
studies
available
for
4­
t­
amylphenol.

Mutagenicity
Potential
The
data
base
for
mutagenicity
is
considered
adequate
based
on
EPA's
1991
mutagenic
guidelines
and
indicates
that
4­
t­
amylphenol
is
not
mutagenic
or
genotoxic.

Endocrine
Disruption
Potential
EPA
is
required
under
the
Federal
Food
Drug
and
Cosmetic
Act
(
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
such
endocrine
effects
as
the
Administrator
may
designate."
4­
t­
Amylphenol
has
properties
that
could
indicate
Endocrine
Disrupting
Chemical
(
EDC)
properties
given
that
available
data
suggest
that
4­
t­
Amylphenol
has
endocrine
disruptor
capabilities
(
uterotrophic
and
estrogenic
effects)
and
increased
billirubin
production
in
babies.

of
1996)
is
intended
to
provide
an
additional
10­
fold
safety
factor
(
10X),
to
protect
for
special
sensitivity
in
infants
and
children
to
specific
pesticide
residues
in
food,
drinking
water,
or
residential
exposures,
or
to
compensate
for
an
incomplete
database.
The
FQPA
Safety
Factor
has
been
9
retained
(
i.
e.,
remains
10X)
for
4­
t­
amylphenol
based
on
the
limited
database,
qualitative
evidence
of
sensitivity
in
the
developmental
toxicity
study,
and
the
suggestive
evidence
in
the
open
literature
of
possible
endocrine
effects.

The
toxicology
data
base
is
not
complete
with
respect
to
assessing
that
increased
susceptibility
to
infants
and
children
as
required
by
FQPA
for
4­
t­
Amylphenol.
The
rat
prenatal
developmental
study
showed
no
quantitative
evidence
of
increased
susceptibility
(
i.
e.,
developmental
NOAELs/
LOAELs
were
higher
than
those
for
maternal
effects).
However,
there
was
qualitative
evidence
of
increased
susceptibility
[
i.
e.,
fetal
effects
(
skeletal
abnormalities,
decreased
body
weight
gain)
were
considered
to
be
more
severe
than
the
maternal
toxicity
(
reversible
clinical
signs)
observed
at
the
same
dose
level].
In
addition,
there
is
an
absence
of
developmental
toxicity
data
in
the
rabbit
and
an
absence
of
reproductive
toxicity
data.

3.
Population
Adjusted
Dose
(
PAD)

Dietary
risk
is
characterized
in
terms
of
the
Population
Adjusted
Dose
(
PAD),
which
reflects
the
reference
dose
(
RfD),
either
acute
or
chronic,
that
has
been
adjusted
to
account
for
the
FQPA
Safety
Factor
(
SF).
This
calculation
is
performed
for
each
population
subgroup.
A
risk
estimate
that
is
less
than
100%
of
the
acute
or
chronic
PAD
is
not
of
concern.

a.
Acute
PAD
Acute
dietary
risk
for
4­
t­
amylphenol
is
assessed
by
comparing
acute
dietary
exposure
estimates
(
in
mg/
kg/
day)
to
the
acute
Population
Adjusted
Dose
(
aPAD).
Acute
dietary
risk
is
expressed
as
a
percent
of
the
aPAD.
The
aPAD
is
the
acute
reference
dose
(
0.67
mg/
kg/
day)
modified
by
the
FQPA
safety
factor.
The
acute
reference
dose
was
derived
from
a
developmental
toxicity
study
in
rats
in
which
both
the
NOAEL
(
200
mg/
kg/
day)
and
the
LOAEL
(
500
mg/
kg/
day)
were
determined.
Acute
dietary
exposure
was
estimated
only
for
females
ages
13­
49
because
available
studies
did
not
show
a
toxicity
endpoint
attributable
to
a
single
exposure
for
the
general
population.
The
4­
t­
amylphenol
aPAD
is
0.067
mg/
kg/
day
based
on
a
reference
dose
of
0.6
mg/
kg/
day,
and
incorporating
the
FQPA
safety
factor
of
10X.

b.
Chronic
PAD
Chronic
dietary
risk
for
4­
t­
Amylphenol
is
assessed
by
comparing
chronic
dietary
exposure
estimates
(
in
mg/
kg/
day)
to
the
chronic
Population
Adjusted
Dose
(
cPAD).
Chronic
dietary
risk
is
expressed
as
a
percent
of
the
cPAD.
The
cPAD
is
the
chronic
reference
dose
(
0.17
mg/
kg/
day)
modified
by
the
FQPA
safety
factor.
The
cPAD
was
derived
from
a
developmental
toxicity
study
in
rats
in
which
both
the
NOAEL
(
50
mg/
kg/
day)
and
the
LOAEL
(
200
mg/
kg/
day)
were
determined.
The
4­
t­
amylphenol
cPAD
is
0.017
mg/
kg/
day
based
on
a
reference
dose
of
0.17
mg/
kg/
day,
which
includes
the
incorporation
of
the
FQPA
safety
factor
(
10X)
for
the
overall
U.
S.
population
or
any
population
subgroups.

4.
Exposure
Assumptions
The
use
of
antimicrobial
chemicals
on
food
or
feed
contact
surfaces,
agricultural
commodities,
in
animal
premises
and
poultry
premises
including
hatcheries
and
application
to
food­
grade
eggs
may
result
in
pesticide
residues
in
human
food.
The
Agency
must
determine
the
risk
to
human
health
that
may
occur
from
exposure
to
these
chemicals.

Refrigerators,
counter
tops,
sinks
and
stoves
are
use
sites
on
registered
labels.
These
surfaces
that
have
been
treated
with
the
4­
t­
amylphenol
products
may
bear
small
residues
of
the
4­
t­
amylphenol
products
after
rinsing
with
potable
water;
i.
e.,
rinsing
with
potable
water
may
not
remove
all
residues
deposited
on
the
treated
surfaces
from
the
proposed
uses.
Residues
from
treated
surfaces
can
migrate
to
food
coming
into
contact
with
the
treated
and
rinsed
surfaces
and
can
be
ingested
by
humans.

In
the
absence
of
residue
data
for
4­
t­
amylphenol
on
treated
food
contact
surfaces,
the
Agency
estimated
residue
levels
that
may
occur
in
food
using
the
highest
application
rate
for
food
contact
surfaces.
To
estimate
the
Estimated
Daily
Intake
(
EDI),
the
Agency
has
used
an
FDA
model.
The
maximum
ingredient
percentage
for
4­
t­
amylphenol
in
food
handling
establishments
from
the
various
labeled
ready­
to­
use
products
is
0.054
%
a.
i
(
540
ppm).
The
Agency
assumed
that
food
can
contact
2000
cm2
of
treated
surfaces,
and
that
10%
of
the
pesticide
migrates
to
food
based
on
the
Agency
Residential
SOPs.
The
use
of
the
10%
transfer
rate
instead
of
the
use
of
a
100%
transfer
rate
that
is
used
in
the
FDA
Sanitizer
Solution
Guidelines
requires
the
submission
of
confirmatory
data
to
establish
the
reliability
of
the
use
of
the10%
transfer
rate.
These
daily
estimates
were
conservatively
used
to
assess
both
acute
and
chronic
dietary.

5.
Dietary
(
Food)
Risk
Assessment
Generally,
a
dietary
risk
estimate
that
is
less
than
100%
of
the
acute
or
chronic
PAD
does
not
exceed
the
Agency's
risk
concerns.
A
summary
of
acute
and
chronic
risk
estimates
are
shown
in
Table
3.

a.
Acute
Dietary
Risk
An
acute
dietary
risk
assessment
was
conducted
for
4­
t­
amylphenol
food
uses.
Dietary
risk
estimates
are
provided
for
females
13­
49
years
old,
the
only
population
subgroup
for
which
an
endpoint
was
selected.
The
result
of
this
assessment
showed
the
risk
estimate
to
be
2.7%
of
the
aPAD
and
therefore
is
not
of
concern
b.
Chronic
(
Non­
cancer)
Dietary
Risk
A
chronic
dietary
risk
assessment
was
conducted
for
4­
t­
amylphenol
food
uses.
The
risk
analysis
assumes
daily
exposure
from
the
hard
surface
disinfection
of
counter
tops.
The
result
of
this
assessment
showed
the
risk
estimates
to
be
<
42%
of
the
cPAD
and
therefore
are
not
of
11
concern.
However,
since
the
Agency
assumed
10%
of
the
residues
are
transferred
to
foods
it
is
requiring
confirmatory
data
for
this
transfer
rate
because
100%
residue
transfer
indicates
risks
of
concern.

Dietary
Risk
from
Drinking
Water
4­
t­
Amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters
based
on
its
use
patterns
and
fate
characteristics.
There
are
no
currently
registered
outdoor
uses
of
4­
t­
amylphenol
and
its
salts.
Further,
the
estimated
value
for
biodegradation
indicates
it
may
biodegrade
linearly
within
days
in
the
aquatic
environment,
although
ultimate
biodegradation
(
mineralization)
may
take
months.
It
also
is
volatile
based
on
its
vapor
pressure
of
0.00116
mmHg,
and
has
a
moderate
to
slight
mobility
in
soils
based
on
its
estimated
Koc
value
of
3799.
The
sodium
and
potassium
salts
of
4­
t­
amylphenol
also
are
slightly
to
moderately
mobile
in
soils,
and
are
estimated
to
biodegrade
within
days
to
weeks.
Because
of
the
possibility
of
biodegradation
in
water
and
soils
and
the
lack
of
outdoor
uses,
4­
t­
amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters.
Thus,
a
drinking
water
assessment
was
not
conducted.

6.
Residential
Exposure
Residential
exposure
assessment
considers
all
potential
pesticide
exposure,
other
than
exposure
due
to
residues
in
food
or
in
drinking
water.
Exposure
may
occur
during
and
after
application
as
a
hard
surface
disinfectant
(
e.
g.,
walls,
floors,
tables,
fixtures),
to
textiles
(
e.
g.,
clothing,
diapers,
mattresses,
bedding)
and
to
carpets.
Each
route
of
exposure
(
oral,
dermal,
inhalation)
is
assessed,
where
appropriate,
and
risk
is
expressed
as
a
Margin
of
Exposure
(
MOE),
which
is
the
ratio
of
estimated
exposure
to
an
appropriate
NOAEL.
Based
on
its
use
patterns,
4­
t­
amylphenol
has
been
assessed
for
the
residential
mixing/
loading/
applicator
(
or
"
handler")
exposure
for
applications
by
homeowners
mopping,
wiping
and
spraying
hard
surfaces.
For
post­
application
exposure,
4­
t­
amylphenol
has
been
assessed
for
adults
and
children
contacting
treated
hard
surfaces/
floors,
wearing
treated
clothing,
wearing
treated
diapers
(
children),
mouthing
treated
textiles
(
children)
and
bystander
inhalation
exposure.

a.
Toxicity
The
toxicological
endpoints
and
associated
uncertainty
factors
used
for
assessing
the
nondietary
risks
for
4­
t­
amylphenol
are
listed
in
Table
4.

A
MOE
greater
than
or
equal
to
3,000
is
considered
adequately
protective
for
the
residential
exposure
assessment
for
the
incidental
oral
and
inhalation
routes
of
exposure.
The
MOE
of
3,000
includes
10x
for
interspecies
extrapolation,
10x
for
intraspecies
variation,
3x
for
database
uncertainty
and
the
10x
FQPA
factor.
For
the
dermal
route
of
exposure,
a
MOE
greater
than
or
equal
to
1,000
is
considered
adequately
protective
for
the
residential
exposure
assessment.
The
MOE
of
1,000
includes
10x
for
interspecies
extrapolation,
10x
for
intraspecies
variation
and
the
10x
FQPA
factor.

i.
Exposure
Scenarios,
Data
and
Assumptions
Residential
exposure
may
occur
during
application
of
4­
t­
amylphenol
as
a
hard
surface
disinfectant
(
e.
g.,
walls,
floors,
tables,
fixtures),
to
textiles
(
e.
g.,
clothing,
diapers,
mattresses,
bedding)
and
to
carpets.
A
number
of
assumptions,
or
estimates,
such
as
adult
body
weight
and
area
treated
per
application,
are
made
by
the
Agency
for
residential
risk
assessment.
Also,
note
that
residential
handlers
are
sometimes
addressed
somewhat
differently
than
occupational
handlers
in
that
homeowners
are
assumed
to
complete
all
elements
of
an
application
(
mix/
load/
apply)
without
the
use
of
personal
protective
equipment.

The
quantitative
exposure/
risk
assessment
developed
for
residential
handlers
is
based
on
these
scenarios:

(
1)
mopping
hard
surfaces,
(
2)
wiping
hard
surfaces,
(
3)
using
trigger
pump
equipment
to
treat
hard
surfaces
and/
or
textiles,
and
(
4)
application
to
air
using
an
aerosol
spray
can
4­
t­
Amylphenol
products
are
widely
used
disinfectants
and
have
a
large
number
of
use
patterns
that
are
difficult
to
completely
capture
in
this
assessment.
As
such,
the
Agency
has
selected
representative
scenarios
for
each
use
site
that
are
believed
to
be
representative
of
the
vast
majority
of
4­
t­
amylphenol
uses,
based
on
end­
use
product
application
methods
and
use
amounts.

Surrogate
data
are
available
for
mopping,
wiping,
trigger
pump
spray
and
aerosol
can
application
methods.
Dermal
and
inhalation
exposures
were
assessed
for
mopping
and
wiping
using
proprietary
Chemical
Manufacturers
Association
(
CMA)
data
(
CMA
1992,
USEPA
1999).
These
data
are
based
on
individuals
mopping
floors
and
receiving
exposure
via
contact
with
the
mop
or
with
the
bucket,
or
using
a
finger
pump
sprayer
to
apply
the
product
and
then
wipe
the
surfaces
with
a
paper
towel.
Dermal
and
inhalation
exposures
were
assessed
for
trigger
pump
spray
and
aerosol
application
methods
using
PHED
Version
1.1
values
found
in
the
Residential
Exposure
SOPs
(
U.
S.
EPA,
1997a,
2001).
The
surrogate
exposure
data
in
PHED
are
based
on
test
subjects
applying
an
aerosol
insecticide
to
baseboards
in
kitchens.
The
dermal
and
inhalation
exposures
from
these
techniques
have
been
normalized
by
the
amount
of
active
ingredient
handled
and
reported
as
unit
exposures
(
UE)
expressed
as
mg/
lb
ai
handled.

In
addition,
product
label
maximum
application
rates,
related
use
information,
and
Agency
standard
values
were
used
to
assess
residential
handler
exposures.
For
example,
it
was
assumed
that
one
gallon
of
diluted
solution
is
used
for
mopping
floors,
while
0.5
liters
(
0.13
gallons)
are
used
in
the
wiping
and
trigger
pump
spray
scenario.
For
aerosol
can
spray,
it
was
assumed
that
one
16
oz
can
of
product
is
used
in
a
day.
The
residential
handler
scenarios
are
assumed
to
be
of
short­
and
intermediate­
term
duration
(
1­
30
days
and
1­
6
months)

ii.
Residential
Handler
Risk
Estimates
Based
on
toxicological
criteria
and
potential
for
exposure,
the
Agency
has
conducted
dermal
and
inhalation
exposure
assessments.
As
noted
previously,
MOEs
greater
than
or
equal
to
3,000
for
the
inhalation
route
of
exposure
and
1,000
for
dermal
exposure
are
considered
adequately
protective
for
the
residential
exposure
assessment.

A
summary
of
the
residential
handler
exposures
and
risk
are
presented
on
Table
5.
For
residential
handlers
that
handle
products
containing
4­
t­
amylphenol
and
its
salts,
short­
term,
and
intermediate­
term
MOEs
were
above
the
target
MOEs
(
i.
e.,
 
>
1000
for
dermal
and
>
3000
for
inhalation)
for
all
scenarios
evaluated
and
thus,
do
not
exceed
the
Agency's
level
of
concern.

Residential
Post­
Application
i.
Exposure
Scenarios,
Data
and
Assumptions
Residential
postapplication
exposures
result
when
bystanders
(
adults
and
children)
come
in
contact
with
4­
t­
amylphenol
in
areas
where
pesticide
end­
use
products
have
recently
been
applied
(
e.
g.,
treated
hard
surfaces/
floors),
or
when
children
incidentally
ingest
the
pesticide
residues
through
mouthing
the
treated
end
products/
treated
articles
(
i.
e.,
hand­
to­
mouth
or
object­
to­
mouth
contact).

For
the
purposes
of
this
screening
level
assessment,
postapplication
scenarios
have
been
developed
that
encompass
multiple
products,
but
still
represent
a
high
end
exposure
scenario
for
all
products
represented.
Representative
postapplication
scenarios
assessed
include:

°
contacting
treated
hard
surfaces/
floors
(
dermal
and
incidental
oral
exposure
to
children),
°
wearing
treated
clothing
(
dermal
exposure
to
adults
and
children),
°
wearing
diapers
treated
with
a
trigger­
pump
spray
(
dermal
exposure
to
children),
°
mouthing
treated
textiles
such
as
clothing
and
blankets
(
incidental
oral
exposure
to
children),
and
15
°
postapplication/
bystander
inhalation
exposures
from
use
of
disinfecting/
deodorizing
products
(
vapor
exposure
to
adults
and
children).

Typically,
most
products
used
in
a
residential
setting
result
in
exposures
occurring
over
a
short­
term
time
duration
(
1
 
30
days).
If
the
products
are
used
on
a
routine
basis
(
i.
e.,
once
a
week)
and
the
active
ingredient
has
a
long
indoor
half­
life,
exposures
may
occur
over
an
intermediate­
term
time
duration
(
30
days
 
6
months).
At
this
time,
the
Agency
does
not
have
residue
dissipation
data
or
reliable
use
pattern
data,
including
the
frequency
and
duration
of
use
of
antimicrobial
products
in
the
residential
setting.
Even
though
the
Agency
does
not
believe
that
the
use
patterns
of
many
residential
products
result
in
intermediate­
term
exposure,
they
are
assessed
to
provide
an
upper
bound
estimate
of
exposure.
The
Agency
does
believe,
however,
that
intermediate­
term
exposure
to
children
may
occur
in
day
care
centers
where
disinfecting
products
are
used
more
frequently.

A
number
of
conservative
assumptions
were
used
in
assessing
postapplication
risks
including
maximum
application
rate
from
the
label.
In
addition
quantities
handled/
treated
were
estimated
based
on
information
from
various
sources,
including
the
Draft
Standard
Operating
Procedures
(
SOPs)
for
Residential
Exposure
Assessments
(
USEPA
2000,
2001)
and
the
AD
Draft
Residential
SOP
use
table.
In
certain
cases,
no
standard
values
were
available
for
some
scenarios.
Assumptions
for
these
scenarios
were
based
on
AD
estimates
and
could
be
further
refined
from
input
from
affected
sectors.
In
the
absence
of
data,
for
both
the
textile
and
diaper
scenarios,
it
was
assumed
that
either
100%
or
5%
of
4­
t­
amylphenol
could
transfer
and
be
available
for
dermal
contact.
The
Agency
will
require
data
to
confirm
the
actual
transfer
factor
of
4­
t­
amylphenol.

No
postapplication
air
concentration
data
have
been
submitted
for
4­
t­
amylphenol
to
determine
potential
vapor
inhalation
risk.
Therefore,
the
Multi­
Chamber
Concentration
and
Exposure
Model
(
MCCEM
v1.2)
was
used
to
present
a
screening­
level
estimate
of
the
potential
inhalation
risk
to
adults
and
children
for
the
air
deodorizer
use.
MCCEM
estimates
average
and
peak
indoor
air
concentrations
of
chemicals
released
from
products
or
materials
in
houses,
apartments,
townhouses,
or
other
residences.
The
data
libraries
in
MCCEM
contain
information
about
residential
settings.
MCCEM
estimates
inhalation
exposures
to
chemicals,
calculated
as
single
day
doses,
chronic
average
daily
doses,
or
lifetime
average
daily
doses.
All
dose
estimates
are
potential
doses;
they
do
not
account
for
actual
absorption
into
the
body.

ii.
Residential
Post­
Application
Risk
Estimates
Based
on
toxicological
criteria
and
potential
for
exposure,
the
Agency
has
conducted
dermal,
incidental
oral
and
inhalation
exposure
assessments.
As
noted
previously,
MOEs
greater
than
or
equal
to
3,000
for
incidental
oral
and
inhalation
exposure
and
1,000
for
dermal
exposure
are
considered
adequately
protective
for
the
residential
exposure
assessment.
A
summary
of
the
residential
post­
application
exposures
and
risk
are
presented
on
Table
6.

The
child
short­
and
intermediate­
term
dermal
MOEs
for
contact
following
hard
surface
disinfection
is
above
the
target
MOE
of
1,000
for
residential
settings
and
slightly
below
the
MOE
for
daycare
centers.
The
short­
and
intermediate­
term
MOEs
for
dermal
contact
with
16
treated
clothing
is
of
concern
for
young
children
(
MOEs
are
<
1
assuming
a
100%
transfer
factor;
MOE=
17
assuming
a
5%
transfer
factor).
For
adults,
the
dermal
MOE
is
below
the
target
MOE
of
1,000
using
a
100%
transfer
factor
(
MOE
=
140)
and
above
the
MOE
using
the
5%
transfer
factor.
The
dermal
MOE
for
children
wearing
treated
diapers
is
only
of
concern
(
MOE=
59)
using
a
transfer
factor
of
100%,
but
it
not
of
concern
when
using
a
transfer
factor
of
5%.
In
addition,
it
should
be
noted
that
4­
t­
amylphenol
caused
dermal
irritant
effects
following
repeated
dermal
exposure,
and
may
also
be
a
potential
dermal
sensitizer.

The
short­
and
intermediate­
term
incidental
oral
MOEs
following
hard
surface
disinfection
are
above
the
target
MOE
of
3,000
for
residential
settings
and
daycare
centers,
and
thus
are
not
of
concern.
However,
the
oral
MOE
for
children
mouthing
treated
textiles
exceeds
the
Agency's
level
of
concern
(
MOE=
650
compared
to
target
MOE>
3,000).

For
both
adults
and
children,
the
calculated
inhalation
MOEs
are
greater
than
the
target
MOE
of
3,000
for
inhalation
exposures
following
use
of
an
air
deodorizer,
and
thus
are
not
of
concern.

Aggregate
Risk
The
Food
Quality
Protection
Act
amendments
to
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA,
Section
408(
b)(
2)(
A)(
ii))
require
"
that
there
is
a
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,
residential
uses
of
a
pesticide,
and
other
non­
occupational
sources
of
exposure.
Since
no
drinking
water
estimates
17
were
developed
for
4­
t­
amylphenol,
aggregate
assessments
include
exposure
to
food
and
as
a
result
of
residential
uses
only.

Typically,
aggregate
risk
assessments
are
conducted
for
acute
(
1
day),
short­
term
(
1­
30
days),
intermediate­
term
(
1­
6
months)
and
chronic
(
6
months
to
lifetime)
exposures.
However,
acute
and
chronic
aggregate
assessments
were
not
conducted
because
there
are
no
significant
impacts
to
drinking
water
sources,
nor
are
there
long­
term
residential
uses.
Thus,
only
short­
and
intermediate­
term
aggregate
assessments
were
conducted.
Oral
and
inhalation
exposure
and
risk
estimates
were
combined
for
the
aggregate
risk
assessment
because
these
endpoints
are
based
on
the
same
toxicity
study
(
oral
developmental
study)
and
effects
of
concern
(
clinical
signs
and
changes
in
body
weight
and
food
consumption).
Dermal
exposures
were
not
aggregated
with
the
oral
or
inhalation
exposures
due
to
different
toxicological
endpoints
for
oral
(
clinical
signs
and
body
weight
changes),
and
dermal
(
no
systemic
effects
at
the
highest
dose
tested).

a.
Short­
and
Intermediate­
Term
Aggregate
Risk
Aggregate
short­
and
intermediate­
term
risk
assessments
are
designed
to
provide
estimates
of
risk
likely
to
result
from
exposures
to
the
pesticide
or
pesticide
residues
in
food,
water,
and
from
residential
(
or
other
non­
occupation)
pesticide
uses.
Short­
and
intermediateterm
aggregate
risks
are
considered
together
because
the
exposure
and
toxicity
endpoints
are
identical
for
incidental
oral
and
inhalation
residential
exposures
for
both
durations.
For
children,
the
short­
and
intermediate­
term
aggregate
assessment
includes
average
dietary
exposure
(
food)
and
estimated
incidental
oral
exposures
to
children
from
residential
uses
such
as
hard
surface
disinfection.
In
addition,
inhalation
exposure
from
postapplication
of
an
air
deodorizer
use
was
aggregated
with
the
oral
exposures
since
the
toxicity
endpoint
is
the
same.
For
adults,
the
aggregate
assessment
includes
dietary
(
oral)
and
residential
inhalation
exposures
from
wiping
a
hard
surface
disinfectant,
in
addition
to
post
application
inhalation
exposure
from
the
air
deodorizer.

The
results
of
the
aggregate
short­
and
intermediate­
term
risk
assessments
are
presented
in
Table
7.
The
aggregate
oral
and
inhalation
risks
are
not
of
concern
for
adults,
as
the
total
aggregate
MOE
is
greater
than
the
target
of
3,000.
For
children,
the
aggregate
risk
estimates
are
also
above
the
target
MOE
of
3,000
and
thus
are
not
of
concern.
As
noted
previously,
incidental
oral
exposures
to
treated
textiles
are
not
included
in
the
aggregate
assessment
because
the
oral
MOE
is
already
of
concern.

A
dermal
aggregate
assessment
was
not
conducted
because
the
toxicity
effects
for
the
dermal
exposure
route
are
not
the
same
as
the
oral/
inhalation
exposure
route.
However,
as
shown
previously
on
Table
6,
short­
and
intermediate
dermal
risks
are
already
of
concern
for
residents
for
the
treated
textile
and
diaper
use.

A
long­

(
or
chronic)
aggregate
assessment
was
not
undertaken
because
the
only
long­
term
residential
use
(
diaper
use)
results
in
dermal
exposure,
which
has
a
different
toxicological
effect
than
the
chronic
dietary
oral
exposure.

Occupational
Exposure
and
Risk
Workers
can
be
exposed
to
a
pesticide
through
mixing,
loading,
and/
or
applying
a
pesticide,
or
re­
entering
treated
sites.
Occupational
handlers
of
4­
t­
amylphenol
include
workers
in
a
variety
of
occupational
settings.
Additionally,
postapplication
exposures
are
likely
to
occur
in
these
settings.
The
representative
scenarios
selected
for
assessment
were
evaluated
using
maximum
application
rates
as
recommended
on
the
product
labels
for
4­
t­
amylphenol.

Occupational
risk
is
assessed
for
exposure
at
the
time
of
application
(
termed
"
handler"
exposure)
and
is
assessed
for
exposure
following
application,
or
post­
application
exposure.
Application
parameters
are
generally
defined
by
the
physical
nature
of
the
formulation
(
e.
g.,
formula
and
packaging),
by
the
equipment
required
to
deliver
the
chemical
to
the
use
site,
and
by
the
application
rate
required
to
achieve
an
efficacious
dose.

Occupational
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)
from
toxicological
studies.
In
the
case
of
4­
tamylphenol
MOEs
greater
than
100
for
dermal
exposures
and
300
for
inhalation
exposures
are
not
of
concern
to
the
Agency.
For
workers
entering
a
treated
site,
MOEs
are
calculated
for
each
day
after
application
to
determine
the
minimum
length
of
time
required
before
workers
can
safely
re­
enter.

Occupational
Handler
Exposure
Potential
occupational
handler
exposure
can
occur
at
various
use
sites,
including
agricultural
premises,
food
handling,
commercial/
institutional/
industrial
premises,
and
medical
premises.
MOEs
are:
>
100
for
dermal
exposure
and;
>
300
for
inhalation
exposure.
Only
the
high
pressure
spray
in
the
agricultural
use
scenario
was
evaluated
using
gloved
data.

The
Agency
has
determined
that
there
is
potential
for
dermal
and
inhalation
worker
exposure
to
4­
t­
amylphenol
at
various
use
sites
including
agricultural
premises,
food
handling,
commercial/
institutional/
industrial
premises,
and
medical
premises.
To
assess
handler
risks,
the
Agency
used
surrogate
unit
exposure
data
from
both
proprietary
Chemical
Manufacturers
(
CMA)
antimicrobial
exposure
study
and
the
Pesticide
Handlers
Exposure
Database
(
PHED).

Summary
For
the
occupational

dermal
and
inhalation
risk
assessment,
the
short­
and
intermediate­
term
risks
calculated
at
baseline
exposure
(
no
gloves
and
no
respirators)
were
above
target
MOEs
for
all
scenarios
(
i.
e.,
dermal
MOEs
were
>
100
and
inhalation
MOEs
were
>
300).
Note,
however,
that
the
high

application
method
in
the
agricultural

category
was
assessed
using
gloved

Occupational
Post­
application
Risk
Summary
For
most
of
the
occupational
scenarios,
postapplication
dermal
exposure
is
not
expected
to
occur
or
is
expected
to
be
negligible
based
on
the
application
rates
and
chemical
properties
of
the
chemical.
Postapplication/
bystander
inhalation
exposures,
however,
were
assessed
for
entry
into
a
building
after
a
fogging
application.
The
representative
building
selected
was
a
poultry
barn.
The
Agency
used
the
MCCEM
(
Multi­
Chamber
Concentration
and
Exposure
Model)
to
estimate
postapplication/
bystander
exposures.
The
calculated
inhalation
MOEs
were
above
the
target
MOE
of
300
for
all
fogging
postapplication
scenarios
with
the
exception
of
the
scenario
for
8­
hr
exposure
to
the
product
with
a
2­
hr
reentry
interval
(
MOE
=
86).

The
Agency
does
not
believe
that
any
mitigation
is
necessary
to
address
the
postapplication
scenario
with
a
2­
hr
reentry
interval
at
this
time.
The
risk
estimate
was
calculated
using
the
Agency's
standard
assumptions
for
air
exchange
rates.
The
Agency
believes
that
in
the
case
of
animal
barns
and
facilities
this
assumption
in
very
conservative
given
the
relatively
high
air
exchange
rates
for
such
facilities.

e.
Human
Incident
Data
There
are
some
reported
incidents
associated
with
exposure
to
end­
use
products
containing
4­
t­
amylphenol.
Dermal,
ocular
and
inhalation
are
the
primary
routes
of
exposure.
Most
of
the
incidents
are
related
to
irritation
reaction.
The
most
common
symptoms
reported
for
cases
of
inhalation
exposure
were
respiratory
irritation/
burning,
irritation
to
mouth/
throat/
nose,
coughing/
choking,
shortness
of
breath,
dizziness,
flu­
like
symptoms,
and
headache.
Eye
pains,
burning
of
eyes,
conjunctivivitis,
blurring
vision,
and
acute
inflammation
have
been
reported
in
ocular
incidents.
Neurological
effects,
such
as
dizziness,
headache
and
blurred
vision
also
have
been
reported.

Environmental
Risk
Assessment
A
summary
of
the
Agency's
environmental
risk
assessment
is
presented
below.
The
following
risk
characterization
is
intended
to
describe
the
magnitude
of
the
estimated
environmental
risks
for
4­
t­
amylphenol
use
sites
and
any
associated
uncertainties.
A
detailed
ecological
hazard
and
environmental
risk
assessment
for
4­
t­
amylphenol
and
its
salts
is
presented
in
"

and
Environmental
Risk
Assessment
for
4­
tert­
amylphenol
and
salts
to
be
included
in
the
RED",
September
2005.
A
brief
summary
is
presented
below.

1.
Environmental
Fate
and
Transport
The
environmental
fate
assessment
for
4­
t­
amylphenol
and
its
potassium
and
sodium
salts
is
based
on
US
EPA
=

s
Estimation
Programs
Interface
(
EPI)
Suite.
EPI
Suite
provides
estimations
of
physical/
chemical
properties
and
environmental
fate
properties.

4­
t­
Amylphenol
may
be
bioaccumlative
(
log
KOW
3.91)
and
is
likely
to
pose
a
concern
for
aquatic
organisms.
It
is
expected
to
have
moderate
to
slight
mobility
in
soils
based
upon
the
estimated
Koc
value
of
3799.
Estimated
value
for
biodegradation
probability
indicates
that
it
22
may
biodegrade
linearly
within
days
in
aquatic
medium.
However,
ultimate
biodegradation
(
mineralization)
may
take
months.
It
is
volatile
and
may
vaporize
into
the
atmosphere.
The
estimated
half
life
in
the
air
for
4­
t­
amylphenol
is
about
three
hours
which
indicates
that
it
is
not
persistent
in
air.
Because
of
the
possibility
of
biodegradation
in
water
and
soils,
it
is
not
likely
to
contaminate
surface
and
ground
waters.

4­
t­
Amylphenol,
potassium
salt,
is
not
likely
to
be
bioaccumlative
(
log
KOW
1.23)
and
may
not
pose
a
concern
for
bioconcentration
in
aquatic
organisms.
It
may
be
expected
to
have
moderate
to
slight
mobility
in
soils
as
its
estimated
Koc
value
is
3799.
Estimated
probability
of
biodegradation
of
4­
t­
amylphenol,
potassium
salt,
in
soils
and
water
indicates
that
it
is
likely
to
biodegrade
within
days
to
weeks.
Therefore,
it
may
be
unlikely
that
soil
and
water
contamination
would
take
place.
It
has
low
volatility
and
its
estimated
half
life
in
air
is
about
4.68
hours
and
is
not
likely
to
be
persistent
in
air.

4­
t­
Amylphenol,
sodium
salt,
is
not
likely
to
be
bioaccumlative
(
log
KOW
is
1.23)
and
may
not
pose
a
concern
for
bioconcentration
in
aquatic
organisms.
It
may
be
expected
to
have
moderate
to
slight
mobility
in
soils
as
its
estimated
Koc
value
is
the
same
as
the
parent
molecule,
4­
t­
amylphenol.
Probability
for
sodium
4­
t­
amylphenate
biodegradation
is
the
same
as
the
parent
molecule,
4­
t­
amylphenol.
Hence,
it
is
not
likely
to
persist
in
soils
and
water,
and
surface
and
ground
water
contamination
is
not
likely
to
occur.
It
has
low
volatility
and
its
estimated
half
life
in
air
is
about
4.68
hours
and
is
not
likely
to
be
persistent
in
air.

2.
Ecological
Risk
Guideline
ecological
effects
data
has
not
submitted
for
4­
t­
amylphenol.
The
only
data
that
was
available
was
found
in
the
peer­
reviewed
literature.
None
of
these
studies
met
current
guideline
requirements
and
therefore,
could
not
be
used
in
a
risk
assessment.
There
is
a
concern
about
the
possibility
of
endocrine
disruption
in
fish,
since
4­
t­
amylphenol
is
considered
an
ecoestrogen.
This
was
documented
in
several
studies
on
carp
(
Cyprimus
carpio).
However,
since
this
chemical
is
restricted
to
indoor
uses
only,
the
possibility
for
exposure
to
fish
to
4­
tamylphenol
would
be
limited.
The
limited
exposure
resulting
from
indoor
uses
of
4­
tamylphenol
and
its
salts
is
not
anticipated
to
cause
adverse
effects
to
terrestrial
or
aquatic
organisms.

The
acute
toxicity
data
for
4­
t­
amylphenol
are
summarized
on
Table
9.
As
shown
in
Table
9,
acute
toxicity
for
freshwater
fish
ranged
from
2.50
mg/
L
to
16
mg/
L
in
the
fathead
minnow.
The
first
study
was
conducted
using
criteria
similar
to
OPP/
OPPTS
guidelines
and
would
have
more
weight
than
the
second
study
which
did
not
provide
any
information
on
how
the
study
was
conducted.
Therefore,
the
data
indicates
that
4­
t­
amylphenol
is
moderately
toxic
to
coldwater
species,
such
as
the
fathead
minnow.
The
fathead
minnow
is
considered
to
be
less
sensitive
than
the
bluegill.
Also
shown
in
Table
9,
acute
toxicity
to
shrimp
was
LC50
=
1.7
mg/
L.
This
indicated
that
4­
t­
amylphenol
was
moderately
toxic
to
shrimp.
The
study
does
not
meet
current
guideline
requirements.

Endocrine
Effects
in
Fish
As
mentioned
above,
potential
endocrine
effects
for
4­
t­
amylphenol
have
been
identified.
Examples
of
the
impacts
of
4­
t­
amylphenol
affecting
the
reproductive
processes
of
carp
have
been
reported
in
the
peer­
reported
literature.
Since
the
use
pattern
for
this
chemical
is
restricted
to
indoor
uses,
exposure
to
fish,
such
as
carp,
should
be
limited.
Therefore,
no
additional
testing
for
endocrine
disruption
effects
on
fish
is
necessary.

Act
Section
7
of
the
Endangered
Species
Act,
16
U.
S.
C.
Section
1536(
a)(
2),
requires
all
federal
agencies
to
consult
with
the
National
Marine
Fisheries
Service
(
NMFS)
for
marine
and
anadromous
listed
species,
or
the
United
States
Fish
and
Wildlife
Services
(
FWS)
for
listed
wildlife
and
freshwater
organisms,
if
they
are
proposing
an
"
action"
that
may
affect
listed
species
or
their
designated
habitat.
Each
federal
agency
is
required
under
the
Act
to
insure
that
any
action
they
authorize,
fund,
or
carry
out
is
not
likely
to
jeopardize
the
continued
existence
of
a
25
listed
species
or
result
in
the
destruction
or
adverse
modification
of
designated
critical
habitat.
To
jeopardize
the
continued
existence
of
a
listed
species
means
"
to
engage
in
an
action
that
reasonably
would
be
expected,
directly
or
indirectly,
to
reduce
appreciably
the
likelihood
of
both
the
survival
and
recovery
of
a
listed
species
in
the
wild
by
reducing
the
reproduction,
numbers,
or

of
the
species."

R.
§
402.02.

To
facilitate
compliance
with
the
requirements
of
the
Endangered
Species
Act
subsection
(
a)(
2)
the
Environmental
Protection
Agency,
Office
of
Pesticide
Programs
has
established
procedures
to
evaluate
whether
a
proposed
registration
action
may
directly
or
indirectly
reduce
appreciably
the
likelihood
of
both
the
survival
and
recovery
of
a
listed
species
in
the
wild
by
reducing
the
reproduction,
numbers,
or
distribution
of
any
listed
species
(
U.
S.
EPA
2004).
After
the
Agency's
screening­
level
risk
assessment
is
performed,
if
any
of
the
Agency's
Listed
Species
LOC
Criteria
are
exceeded
for
either
direct
or
indirect
effects,
a
determination
is
made
to
identify
if
any
listed
or
candidate
species
may
co­
occur
in
the
area
of
the
proposed
pesticide
use.
If
determined
that
listed
or
candidate
species
may
be
present
in
the
proposed
use
areas,
further
biological
assessment
is
undertaken.
The
extent
to
which
listed
species
may
be
at
risk
then
determines
the
need
for
the
development
of
a
more
comprehensive
consultation
package
as
required
by
the
Endangered
Species
Act.

For
certain
use
categories,
the
Agency
assumes
there
will
be
minimal
environmental
exposure,
and
only
a
minimal
toxicity
data
set
is
required
(

Chemicals
in
these
categories
therefore
do
not
undergo
a
full
screening­
level
risk
assessment,
and
are
considered
to
fall
under
a
"

determination.
Due
to
the
low
likelihood
of
exposure
form
the
indoor
uses
of
4­
t­
amylphenol
,
the
Agency
expects
no
effects
to
listed
species
or
critical

and
therefore
makes
a
"
No

determination
for
this
chemical.

Amylphenol
end­
use
products
(
EPs)
may
also
contain
other
registered
pesticides.
Although
the
Agency
is
not
proposing
any
mitigation
measures
for
products
containing
4­
tamylphenol
specific
to
federally
listed
species,
the
Agency
needs
to
address
potential
risks
from
other
end­
use
products.
Therefore,
the
Agency
requires
that
users
adopt
all
listed
species
risk
mitigation
measures
for
all
active
ingredients
in
the
product.
If
a
product
contains
multiple
active
ingredients
with
conflicting
listed
species
risk
mitigation
measures,
the
more
stringent
measure(
s)
should
be
adopted.

Decision
A.
Determination
of
Reregistration
Eligibility
Section
4(
g)(
2)(
A)
of
FIFRA
calls
for
the
Agency
to
determine,
after
submission
of
relevant
data
concerning
an
active
ingredient,
whether
or
not
products
containing
the
active
ingredient
are
eligible
for
reregistration.
The
Agency
has
previously
identified
and
required
the
submission
of
the
generic
(
i.
e.,
active
ingredient­
specific)
data
required
to
support
reregistration
of
products
containing
4­
t­
amylphenol
and
its
salts
(
potassium
and
sodium)
as
active
ingredients.
The
Agency
has
completed
its
review
of
these
generic
data,
and
has
determined
that
the
data
are
sufficient
to
support
reregistration
of
all
supported
products
containing
4­
t­
amylphenol
and
salts,

The
Agency
has
completed
its
assessment
of
the
dietary,
occupational,
drinking
water
and
ecological
risks
associated
with
the
use
of
pesticide
products
containing
the
active
ingredients
4­
t­
amylphenol.
Based
on
a
review
of
these
data
and
on
public
comments
on
the
Agency's
assessments
for
the
active
ingredients
4­
t­
amylphenol
and
its
salts
(
potassium
and
sodium),
the
Agency
has
sufficient
information
on
the
human
health
and
ecological
effects
of
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
products
containing
4­
t­
amylphenol
and
its
salts
are
eligible
for
reregistration
provided
that:
(
i)
current
data
gaps
and
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
4­
t­
amylphenol
and
salts
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
4­
t­
amylphenol
and
salts,
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
4­
t­
amylphenol
and
salts,
the
Agency
has
determined
that
4­
tamylphenol
and
salts
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
the
use
of
4­
t­
amylphenol
and
salts.
If
all
changes
outlined
in
this
document
are
incorporated
into
the
product
labels,
then
all
current
risks
for
4­
t­
amylphenol
and
salts
(
potassium
and
sodium)
will
be
substantially
mitigated
for
the
purposes
of
this
determination.

B.
Public
Comments
and
Responses
Through
the
Agency's
public
participation
process,
EPA
worked
with
stakeholders
and
the
public
to
reach
the
regulatory
decisions
for
4­
t­
amylphenol.
During
the
public
comment
period
on
the
risk
assessments,
which
closed
on
September
19,
2005,
the
Agency
received
comments
from
the
Clariant
Corporation
regarding
risk
assessment
assumptions
and
endocrine
disruption
potential
and
from
a
private
citizen
concerned
about
the
diaper
use
of
this
chemical.

Act
(
FQPA)
Considerations
a.
"
Risk
Cup"
Determination
As
part
of
the
FQPA
tolerance
reassessment
process,
EPA
assessed
the
risks
associated
with
4­
t­
amylphenol.
The
Agency
has
concluded
that
the
tolerance
exemption
for
4­
tamylphenol
meets
the
FQPA
safety
standards
and
that
the
risk
from
dietary
(
food
sources
only)
exposure
is
within
the
"
risk
cup."
An
aggregate
assessment
was
conducted
for
exposures
through
food,
drinking
water
and
residential
exposure.
The
Agency
has
determined
that
the
human
health
risks
from
these
combined
exposures
are
within
acceptable
levels
provided
that
the
mitigation
contained
in
this
document
is
implemented.
In
reaching
this
determination,
EPA
has
considered
the
available
information
on
the
special
sensitivity
of
infants
and
children,
as
well
as
aggregate
exposure
from
food,
water
and
residential
exposures.

b.
Determination
of
Safety
to
U.
S.
Population
As
part
of
the
FQPA
tolerance
reassessment
process,
EPA
assessed
the
risks
associated
with
4­
t­
amylphenol
and
its
salts
(
potassium
and
salts).
The
Agency
has
determined
that
the
established
tolerance
exemption
for
4­
t­
amylphenol
and
its
salts
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,
and
that
there
is
a
reasonable
certainty
no
harm
will
result
to
the
general
population
or
any
subgroup
from
the
reregistered,
labeled
uses
of
4­
t­
amylphenol
and
salts.
In
reaching
this
conclusion,
the
Agency
has
considered
all
available
information
on
the
toxicity,
use
practices
and
exposure
scenarios,
and
the
environmental
behavior
of
4­
t­
amylphenol
and
its
salts.
Both
the
acute
dietary
(
food
alone)
and
chronic
dietary
risks
from
4­
t­
amylphenol
are
not
of
concern.
4­
t­
Amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters
based
on
its
use
patterns
and
fate
characteristics.
Thus,
a
drinking
water
assessment
was
not
conducted.

Short­
and
intermediate­
term
aggregate
risk
assessments
were
conducted
for
4­
tamylphenol
The
aggregate
oral
and
inhalation
risks
are
not
of
concern
for
adults,
as
the
total
aggregate
MOE
is
greater
than
the
target
of
3,000.
For
children,
the
aggregate
risk
estimates
are
also
above
the
target
MOE
of
3,000
and
thus
are
not
of
concern.
As
noted
previously,
incidental
oral
exposures
to
treated
textiles
are
not
included
in
the
aggregate
assessment
because
the
oral
MOE
is
already
of
concern.

A
dermal
aggregate
assessment
was
not
conducted
because
the
toxicity
effects
for
the
dermal
exposure
route
are
not
the
same
as
the
oral/
inhalation
exposure
route.
However,
as
shown
previously
on
Table
6,
short­
and
intermediate
dermal
risks
are
already
of
concern
for
the
treated
textile
and
diaper
uses.
28
c.
Determination
of
Safety
to
Infants
and
Children
EPA
has
determined
that
the
established
tolerance
exemption
for
4­
t­
amylphenol,
with
amendments
and
changes
as
specified
in
this
document,
meets
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
factors
of
the
toxicity,
use
practices,
and
environmental
behavior
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
4­
t­
amylphenol
residues
in
this
population
subgroup.

A
Special
FQPA
Safety
Factor
is
necessary
to
protect
the
safety
of
infants
and
children.
In
determining
whether
or
not
infants
and
children
are
particularly
susceptible
to
toxic
effects
from
4­
t­
amylphenol
residues,
the
Agency
considered
the
completeness
of
the
database
for
developmental
and
reproductive
effects,
the
nature
of
the
effects
observed,
and
other
information.
The
FQPA
Safety
Factor
has
been
retained
(
i.
e.,
remains
10X)
for
4­
t­
amylphenol
based
on
a
lack
of
guideline
studies,
qualitative
evidence
of
sensitivity
in
the
developmental
toxicity
study,
and
the
suggestive
evidence
in
the
open
literature
of
possible
endocrine
effects.

The
toxicology
data
base
is
not
complete
with
respect
to
assessing
that
increased
susceptibility
to
infants
and
children
as
required
by
FQPA
for
4­
t­
amylphenol.
The
rat
prenatal
developmental
study
showed
no
quantitative
evidence
of
increased
susceptibility
(
i.
e.,
developmental
NOAELs/
LOAELs
were
higher
than
those
for
maternal
effects).
However,
there
was
qualitative
evidence
of
increased
susceptibility
(
i.
e.,
fetal
effects
(
skeletal
abnormalities,
decreased
body
weight
gain)
were
considered
to
be
more
severe
than
the
maternal
toxicity
(
reversible
clinical
signs)
observed
at
the
same
dose
level).
In
addition,
there
is
an
absence
of
developmental
toxicity
data
in
the
rabbit
and
an
absence
of
reproductive
toxicity
data.

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
a
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
effect
in
humans,
FFDCA
authority
to
require
the
wildlife
evaluations.
As
the
science
develops
and
resources
allow,
screening
of
additional
hormone
systems
may
be
added
to
the
Endocrine
Disruptor
Screening
Program
(
EDSP).
29
When
the
appropriate
screening
and/
or
testing
protocols
being
considered
under
the
EDSP
have
been
developed,
4­
t­
amylphenol
may
be
subject
to
additional
screening
and/
or
testing
to
better
characterize
effects
related
to
endocrine
disruption.

e.
Cumulative
Risks
Risks
summarized
in
this
document
are
those
that
result
only
from
the
use
of
4­
tamylphenol
and
salts.
The
Food
Quality
Protection
Act
(
FQPA)
requires
that
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
reason
for
consideration
of
other
substances
is
due
to
the
possibility
that
low­
level
exposures
to
multiple
chemical
substances
that
cause
a
common
toxic
effect
by
a
common
toxic
mechanism
could
lead
to
the
same
adverse
health
effect
as
would
a
higher
level
of
exposure
to
any
of
the
substances
individually.
Unlike
other
pesticides
for
which
EPA
has
followed
a
cumulative
risk
approach
based
on
a
common
mechanism
of
toxicity,
EPA
has
not
made
a
common
mechanism
of
toxicity
finding
for
4­
t­
amylphenol.
For

EPA's
efforts

such
chemicals,

D.
Regulatory
Rationale
The
Agency
has
determined
that
4­
t­
amylphenol
is
eligible
for
reregistration
provided
that
additional
required
data
confirm
this
decision
and
that
the
risk
mitigation
measures
outlined
in
this
document
are
adopted,
and
label
amendments
are
made
to
reflect
these
measures.

The
following
is
a
summary
of
the
rationale
for
managing
risks
associated
with
the
use
of
4­
t­
amylphenol.
Where
labeling
revisions
are
warranted,
specific
language
is
set
forth
in
the
summary
tables
of
Section
V
of
this
document.

1.
Human
Health
Risk
Management
a.
Dietary
(
Food)
Risk
Mitigation
For
all
supported
uses,
the
acute
and
chronic
dietary
exposure
estimates
are
below
the
Agency's
level
of
concern.
Therefore,
no
risk
mitigation
measures
are
required
to
address
exposure
to
4­
t­
amylphenol
residues
in
food.
Residue
data
are
required
to
confirm
the
10%
transfer
assumption
used
in
the
risk
assessment.

b.
Drinking
Water
Risk
Mitigation
4­
t­
Amylphenol
and
its
salts
are
not
likely
to
contaminate
surface
and
ground
waters
based
on
its
use
patterns
and
fate
characteristics.
Thus,
a
drinking
water
assessment
was
not
conducted.
Therefore,
no
risk
mitigation
measures
are
required
to
address
4­
t­
amylphenol
exposure
from
drinking
water.

c.
Residential
Risk
Mitigation
Residential
risks
from
handler
and
post­
application
exposure
were
calculated
for
shortand
intermediate­
term
dermal,
inhalation
and
incidental
oral
exposures.
All
exposure
and
risk
estimates
for
residential
handler
scenarios
are
below
the
Agency's
level
of
concern.
Therefore,
no
risk
mitigation
measures
are
required
for
these
handler
scenarios.

Risks
of
concern
have
been
identified
for
several
post­
application
exposure
scenarios
including
children's
dermal
exposure
to
treated
clothing
and
treated
diapers
and
children's
incidental
oral
exposure
to
treated
clothing.
The
Agency
believes
that
adding
clear
instructions
for
washing
and
rinsing
textile
items
will
result
in
the
adequate
removal
of
residues
from
the
treated
items
and
address
the
Agency's
concerns
for
this
scenario.
The
MOE
for
dermal
exposure
to
children
to
treated
surfaces
in
daycare
centers
slightly
exceeds
the
Agency's
level
of
concern
(
MOE
=
940
with
a
target
MOE
of
1,000).
However,
the
Agency
believes
actual
exposure
from
this
pathway
to
not
exceed
its
level
of
concern
when
taking
into
account
the
conservative
nature
of
the
risk
estimate
which
is
likely
to
overestimate
potential
exposures.
31
In
summary,
to
reduce
residential
exposure,
the
Agency
has
determined
that
the
following
mitigation
and
label
changes
for
specific
scenarios
are
appropriate
and
required
for
reregistration
eligibility:

­
Delete
all
diaper
uses
­
Delete
all
use
on
non­
laundered
textiles\
items
including
mattresses,
helmets,
headgear,
headphones,
face
gear,
and
mouthpieces.
­
All
labels
with
laundered
textile
uses
must
have
directions
that
indicate
that
items
must
be
treated
prior
to
washing
and
rinsing.

d.
Occupational
Risk
Mitigation
i.
Handler
Exposure
Occupational
risks
from
handler
and
applicator
exposures
were
calculated
for
short­
term
and
intermediate­
term
dermal
and
inhalation
exposures.
All
exposure
and
risk
estimates
for
occupational
handler
scenarios
are
below
the
Agency's
level
of
concern.
Therefore,
no
risk
mitigation
measures
are
required
for
these
handler
scenarios.

ii.
Post­
Application
Risk
Mitigation
Post­
application
exposure
to
re­
entry
workers
is
possible
because
4­
t­
amylphenol
can
be
applied
as
a
fogging
application
to
animal
buildings.
The
Agency
used
the
MCCEM
(
Multi­
Chamber
Concentration
and
Exposure
Model)
to
estimate
postapplication/
bystander
exposures.
The
calculated
inhalation
MOEs
were
above
the
target
MOE
of
300
for
all
fogging
postapplication
scenarios
with
the
exception
of
the
scenario
for
8­
hr
exposure
to
the
product
with
a
2­
hr
reentry
interval
(
MOE
=
86).

The
Agency
does
not
believe
that
any
mitigation
is
necessary
to
address
the
postapplication
scenario
with
a
2­
hr
reentry
interval
at
this
time.
The
risk
estimate
was
calculated
using
the
Agency's
standard
assumptions
for
air
exchange
rates.
The
Agency
believes
that
in
the
case
of
animal
barns
and
facilities
this
assumption
is
very
conservative
given
the
relatively
high
air
exchange
rates
for
such
facilities.

2.
Environmental
Risk
Management
As
the
uses
of
4­
t­
amylphenol
considered
in
this
RED
make
it
unlikely
that
any
appreciable
exposure
to
terrestrial
or
aquatic
organisms
would
occur,
no
risk
mitigation
measures
are
required
to
address
environmental
exposure
to
4­
t­
amylphenol.

3.
Other
Labeling
Requirements
In
order
to
be
eligible
for
reregistration,
various
use
and
safety
information
will
be
included
in
the
labeling
of
all
end­
use
products
containing
4­

Act
Section
7
of
the
Endangered
Species
Act,
16
U.
S.
C.
Section
1536(
a)(
2),
requires
all
federal
agencies
to
consult
with
the
National
Marine
Fisheries
Service
(
NMFS)
for
marine
and
anadromous
listed
species,
or
the
United
States
Fish
and
Wildlife
Services
(
FWS)
for
listed
wildlife
and
freshwater
organisms,
if
they
are
proposing
an
"
action"
that
may
affect
listed
species
or
their
designated
habitat.
Each
federal
agency
is
required
under
the
Act
to
insure
that
any
action
they
authorize,
fund,
or
carry
out
is
not
likely
to
jeopardize
the
continued
existence
of
a
listed
species
or
result
in
the
destruction
or
adverse
modification
of
designated
critical
habitat.
To
jeopardize
the
continued
existence
of
a
listed
species
means
"
to
engage
in
an
action
that
reasonably
would
be
expected,
directly
or
indirectly,
to
reduce
appreciably
the
likelihood
of
both
the
survival
and
recovery
of
a
listed
species
in
the
wild
by
reducing
the
reproduction,
numbers,
or
distribution
of
the
species."

§
402.02.

To
facilitate
compliance
with
the
requirements
of
the
Endangered
Species
Act
subsection
(
a)(
2)
the
Environmental
Protection
Agency,
Office
of
Pesticide
Programs
has
established
procedures
to
evaluate
whether
a
proposed
registration
action
may
directly
or
indirectly
reduce
appreciably
the
likelihood
of
both
the
survival
and
recovery
of
a
listed
species
in
the
wild
by
reducing
the
reproduction,
numbers,
or
distribution
of
any
listed
species
(
U.
S.
EPA
2004).
After
the
Agency's
screening­
level
risk
assessment
is
performed,
if
any
of
the
Agency's
Listed
Species
LOC
Criteria
are
exceeded
for
either
direct
or
indirect
effects,
a
determination
is
made
to
identify
if
any
listed
or
candidate
species
may
co­
occur
in
the
area
of
the
proposed
pesticide
use.
If
determined
that
listed
or
candidate
species
may
be
present
in
the
proposed
use
areas,
further
biological
assessment
is
undertaken.
The
extent
to
which
listed
species
may
be
at
risk
then
determines
the
need
for
the
development
of
a
more
comprehensive
consultation
package
as
required
by
the
Endangered
Species
Act.

For
certain
use
categories,
the
Agency
assumes
there
will
be
minimal
environmental
exposure,
and
only
a
minimal
toxicity
data
set
is
required
(

Chemicals
in
these
categories
therefore
do
not
undergo
a
full
screening­
level
risk
assessment,
and
are
considered
to
fall
under
a
"
no
effect"
determination.
Due
to
the
low
likelihood
of
exposure
of
4­
t­
amylphenol,
the
Agency
expects
no
effects
to
listed
species
or
critical
habitat
and
therefore
makes
a
"
No
Effect"
determination
for
this
chemical.

General
Risk
Mitigation
4­
t­
Amylphenol
end
use
products
(
EPs)
may
also
contain
other
registered
pesticides.
Although
the
Agency
is
not
proposing
any
mitigation
measures
for
products
containing
4­
tamylphenol
specific
to
federally
listed
threatened
and
endangered
species,
the
Agency
needs
to
address
potential
risks
from
other
end­
use
products.
Therefore,
the
Agency
requires
that
users
adopt
all
threatened
and
endangered
species
risk
mitigation
measures
for
all
active
ingredients
in
33
the
product.
If
a
product
contains
multiple
active
ingredients
with
conflicting
threatened
and
endangered
species
risk
mitigation
measures,
the
more
stringent
measure(
s)
should
be
adopted.

V.
What
Registrants
Need
to
Do
The
Agency
has
determined
that
4­
t­
amylphenol
is
eligible
for
reregistration
provided
that:
(
i)
additional
data
that
the
Agency
intends
to
require
confirm
this
decision;
and
(
ii)
the
risk
mitigation
measures
outlined
in
this
document
are
adopted,
and
(
iii)
label
amendments
are
made
to
reflect
these
measures.
To
implement
the
risk
mitigation
measures,
the
registrants
must
amend
their
product
labeling
to
incorporate
the
label
statements
set
forth
in
the
Label

Additional
Generic
Data
Requirements
The
generic
database
supporting
the
reregistration
of
4­
t­
amylphenol
has
been
reviewed
and
determined
to
be
substantially
complete.
However,
the
following
additional
data
requirements
have
been
identified
by
the
Agency
as
confirmatory
and
included
in
the
generic
DCI
for
this
RED.

The
Agency
has
established
an
interim
two­
tiered
system
for
toxicology
testing
requirements.
Tier
I
toxicology
data
requirements
would
apply
to
all
indirect
food
additives
that
result
in
residue
concentrations
ranging
from
0­
200ppb
which
applies
to
4­
t
amylphenol.
The
requirements
would
consist
of
an
acute
toxicity
testing
battery,
subchronic
toxicity
studies
in
the
rodent,
a
developmental
toxicity
study
in
the
rat,
and
a
mutagenicity
testing
battery.
The
developmental
toxicity
study
in
the
rat,
mutagenicity
testing
battery,
the
acute
oral
toxicity
and
the
acute
dermal
irritation
data
requirements
has
been
fulfilled
for
4­
t
amylphenol.
The
Agency
also
conducts
a
literature
search
and
can
also
conduct
a
Structural
Activity
Relationship
analysis
(
SAR)
if
appropriate.
The
Agency
also
will
hold
in
reserve
a
two­
generation
reproduction
toxicity
study
in
the
rat
and
a
subchronic
toxicity
studies
in
a
non­
rodent
which
would
become
data
requirements
if
warranted
by
the
Agency's
evaluation
of
the
Tier
1
data.
A
2­
generation
reproduction
study
and
a
subchronic
toxicity
study
in
a
non­
rodent
are
being
held
in
reserve
for
4­
t
amylphenol.

Tier
II
studies
would
be
triggered
by
the
presence
of
significant
(
i.
e.
>
200ppb)
residues
in
food
or
evidence
of
significant
toxicity
from
the
Tier
I
data
set,
which
may
include
developmental
/
reproductive,
or
other
systemic
toxicity
such
as
presence
of
neoplastic
growth
or
significant
target
organ
toxicity.
In
such
cases,
chronic
toxicity
and
carcinogenicity
testing
would
be
required.

As
mentioned
earlier,
the
Agency
assumed
that
food
can
contact
2000
cm2
of
treated
surfaces,
and
that
10%
of
the
pesticide
migrates
to
food
based
on
the
Agency
Residential
SOPs
in
its
dietary
risk
assessment.
The
use
of
the
10%
transfer
rate
instead
of
the
use
of
a
100%
transfer
rate
that
is
used
in
the
FDA
Sanitizer
Solution
Guidelines
requires
the
submission
of
confirmatory
data
to
establish
the
reliability
of
the
use
of
the10%
transfer
rate.

The
Agency
is
also
holding
in
reserve
a
developmental
toxicity
study
in
rabbits
based
on
the
potential
endocrine
disruption
effects
of
this
chemical.
The
need
for
this
study
will
be
determined
following
the
Agency's
review
of
the
90­
day
oral
study
in
rodents.

The
risk
assessment
noted
deficiencies
in
the
surrogate
dermal
and
inhalation
exposure
data
available
from
the
Chemical
Manufacturers
Association
(
CMA)
data
base.
Therefore,
the
Agency
is
requiring
confirmatory
data
to
support
the
uses
assessed
with
the
CMA
exposure
data
within
this
risk
assessment.
The
risk
assessment
also
noted
that
many
of
the
use
parameters
37
(
e.
g.,
amount
handled
and
duration
of
use)
were
based
on
professional
judgments.
Therefore,
descriptions
of
human
activities
associated
with
the
uses
assessed
are
required
as
confirmatory.

A
28­
day
rat
inhalation
study
for
hazard
considerations
because
4­
t­
amylphenol
is
an
air
deodorizer
was
considered,
however,
the
Agency
does
not
believe
this
study
is
necessary
because
the
MOEs
are
sufficiently
high
for
this
use,
and
thus
not
of
concern.
In
addition,
the
Agency
believes
the
repeat
dermal
toxicity
study
with
end
use
formulation
product,
and
confirmatory
residue
migration
data
are
not
necessary
because
the
diaper
and
textile
use
are
no
longer
eligible
for
registration.

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
4­
t­
amylphenol
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
sixdigit
"
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
75
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.

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.

Batching
of
Products
for
Meeting
Acute
Toxicity
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
4­
t­
amylphenol
as
the
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
that
the
Agency
is
not
describing
batched
products
as
"
substantially
similar"
since
some
products
within
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.
Not
with­
standing
the
batching
process,
the
Agency
reserves
the
right
to
require,
at
any
time,
acute
toxicity
data
for
an
individual
product
should
the
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
a
batch,
or
to
generate
all
the
required
acute
toxicological
studies
for
each
of
their
own
products.
If
a
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
a
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
today's
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,
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
a
registrant
supplies
the
data
to
support
a
batch
of
products,
he/
she
must
select
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
6).
If
a
registrant
depends
on
another's
82
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.

The
batching
information
will
