II.
What
Action
is
the
Agency
Taking?
EPA
has
assessed
the
risks
of
tetrachlorvinphos
and
reached
an
Interim
Tolerance
Reassessment
Eligibility
Decision
(
TRED)
or
a
Report
on
FQPA
Tolerance
Reassessment
Progress
and
Interim
Risk
Management
Decision
for
this
pesticide.
With
risk
mitigation
measures
adopted,
tetrachlorvinphos
fits
into
its
own
risk
cup­
its
individual,
aggregate
risks
are
within
acceptable
levels.
The
RED
for
tetrachlorvinphos
was
completed
in
1995.
At
that
time,
the
Agency
assessed
the
risk
for
dietary,
occupational,
ecological,
and
residential
concerns.
With
the
passage
of
FQPA,
the
tolerances
for
tetrachlorvinphos
needed
to
be
reassessed
according
to
the
FQPA
safety
standard.
In
this
current
assessment,
the
Agency
looked
at
dietary,
residential
and
occupational
concerns.
Tetrachlorvinphos
is
currently
applied
dermally
to
livestock
to
control
flies
and
mites;
used
as
a
feed­
through
(
oral)
larvicide
in
cattle,
hogs,
goats,
and
horses;
in
cattle
ear
tags
to
control
flies;
and
in
poultry
production
to
control
beetles,
flies,
and
mites.
Tetrachlorvinphos
also
is
used
as
a
dust/
powder,
aerosol,
and
pump
spray
on
pets
and
in
pet
sleeping
areas,
and
in
collars
and
shampoos
for
direct
treatment
of
pets.
It
is
used
as
a
spray
to
control
nuisance
and
public
health
pests
(
flies)
in
and
around
refuse
sites,
recreational
areas,
and
for
general
outdoor
treatment.
Dietary
risks
from
eating
food
items
containing
residues
of
tetrachlorvinphos
are
below
the
level
of
concern
for
the
entire
U.
S.
population,
including
infants
and
children.
Drinking
water
is
not
a
significant
source
of
exposure.
Residential
handler
and
post
application
risks
were
also
not
of
concern
for
all
exposure
scenarios.
However,
the
Agency
has
concern
over

the
potential
for
over­
application
of
powder
products.
Labels
need
to
be
modified
to
specify
how
much
product
to
apply
to
treat
pets
of
different
sizes.
Additionally,
based
on
discussions
with
stakeholders,
EPA
believes
that
directions
for
outdoor
uses
as
premise
sprays
around
kennels,
yards,
campgrounds,
and
parks,
and
along
foot
paths
and
roadways
leading
to
such
areas,
must
clearly
limit
use
to
spot
treatments
only.
Worker
risks
for
most
scenarios
are
not
of
concern
if
measures
to
reduce
exposure,
such
as
personal
protective
equipment,
are
used.
However,
use
of
the
EC
formulation
as
a
paint­
on
poses
high
risks
to
workers
despite
the
maximum
protection
feasible.
Therefore
this
use
will
be
removed
from
product
labels.
For
other
scenarios,
such
as
applying
dusts
with
power
dusting
equipment,
additional
data
are
needed
to
confirm
that
risks
to
workers
will
not
be
excessive.
In
addition,
EPA
has
determined
that
labels
for
tetrachlorvinphos
feedthrough
products
for
horses
must
state
that
the
product
is
a
chlolinesterase
inhibitor,
describe
signs
of
cholinesterase
inhibition
in
horses,
caution
against
the
use
with
other
cholinesterase
inhibiting
compounds,
and
direct
horse
owners
to
consult
a
veterinarian
before
using
products
containing
tetrachlorvinphos
on
debilitated,
aged,
breeding,
pregnant
or
nursing
animals.
The
interim
risk
management
decision
document
for
tetrachlorvinphos
was
made
through
the
organophosphate
pesticide
pilot
public
participation
process,
which
increases
transparency
and
maximizes
stakeholder
involvement
in
EPA's
development
of
risk
assessments
and
risk
management
decisions.
The
pilot
public
participation
process
was
developed
as
part
of
the
EPA­
USDA
Tolerance
Reassessment
Advisory
Committee
(
TRAC),
which
was
established
in
April
1998,
as
a
subcommittee
under
the
auspices
of
EPA's
National
Advisory
Council
for
Environmental
Policy
and
Technology.
A
goal
of
the
pilot
public
participation
process
is
to
find
a
more
effective
way
for
the
public
to
participate
at
critical
junctures
in
the
Agency's
development
of
organophosphate
pesticide
risk
assessments
and
risk
management
decisions.
EPA
and
USDA
began
implementing
this
pilot
process
in
August
1998,
to
increase
transparency
and
opportunities
for
stakeholder
consultation.
EPA
worked
extensively
with
affected
parties
to
reach
the
decisions
presented
in
the
interim
risk
management
decision
documents,
which
conclude
the
pilot
public
participation
process
for
tetrachlorvinphos.
As
part
of
the
pilot
public
participation
process,
numerous
opportunities
for
public
comment
were
offered
as
these
interim
risk
management
decision
documents
were
being
developed.
The
tetrachlorvinphos
interim
risk
management
decision
document
therefore
is
issued
in
final,
without
a
formal
public
comment
period.
The
docket
remains
open,
however,
and
any
comments
submitted
in
the
future
will
be
placed
in
the
public
docket.
The
risk
assessments
for
tetrachlorvinphos
were
released
to
the
public
through
a
notice
published
in
the
Federal
Register
of
January
15,
1999
(
64
FR
2644)
(
FRL
 
6056
 
9)
and
March
27,
2000
(
65
FR
16197)
(
FRL
 
6551
 
4).
Addenda
to
these
assessments
are
also
available
in
the
public
docket.
EPA's
next
step
under
FQPA
is
to
complete
a
cumulative
risk
assessment
and
risk
management
decision
for
the
organophosphate
pesticides,
which
share
a
common
mechanism
of
toxicity.
The
interim
risk
management
decision
document
on
tetrachlorvinphos
cannot
be
considered
final
until
this
cumulative
assessment
is
complete.
When
the
cumulative
risk
assessment
for
the
organophosphate
pesticides
has
been
completed,
EPA
will
issue
its
final
tolerance
reassessment
decision
for
tetrachlorvinphos
and
further
risk
mitigation
measures
may
be
needed.
