The
RED
was
completed
before
the
implementation
of
FQPA.
A
TRED
needs
to
be
completed
to
satisfy
the
requirements
of
FQPA.
Therefore,
the
review
team
will
be
working
on
the
dietary
exposure
aspect
of
the
pesticide's
use.
(
There
are
no
residential
uses
of
4­
CPA.)

Lead
Risk
Assessor
(
Carol
Christensen)
reported
that
4­
CPA
will
be
assessed
through
the
inerts/
low
toxicity
review
process
rather
than
the
traditional
SARC
(
science
review
committee)
process.
This
should
greatly
expedite
the
risk
assessment.

Currently,
there
are
two
tolerances,
one
for
tomatoes
and
one
for
mung
beans.
The
registrant
petitioned
the
Agency
to
delete
the
tomato
tolerance
and
reduce
the
mung
bean
tolerance
from
2.0
ppm
to
0.2
ppm
at
the
time
of
the
RED.
Further,
there
is
a
metabolite
in
the
tolerance
expression
that
was
proposed
to
be
removed.
None
of
the
tolerance
changes
have
been
accomplished
to
date.

Dick
Otten
stated
that
there
has
been
no
new
data
generated
or
submitted
since
the
time
of
the
RED.
He
reiterated
that
the
only
use
is
an
indoor
operation,
with
no
outdoor
use.

Several
questions
were
posed
by
OPP
staff,
about
how
much
4­
CPA
is
now
used
annually,
how
often,
at
how
many
production
sites,
and
how
the
(
effluent
and
landfill)
disposal
practice
occurs.
Mr.
Otten
indicated
that
he
will
get
updated
information
on
usage
and
attempt
to
find
the
old
video
that
demonstrates
how
the
process
is
done.
In
the
past,
one
batch
of
active
ingredient
that
lasts
for
several
years
was
manufactured.
Approximately
50
lbs
of
a.
i.
is
used
annually
at
one
site.
It
is
not
clear
if
one
or
more
sites
have
been
added
since
the
RED
was
completed.

In
addition
to
quantitative
use
information,
Mr.
Otten
agreed
to
look
for
any
additional
information
on
metabolism
of
4­
CPA
and
any
incident
data.
