MEMORANDUM
SUBJECT:
Tolerance
Reassessment
Decisions
Regarding
Exemptions
from
a
Tolerance
for
Two
Viral

PIPs
(

FROM:
Janet

Andersen,
Director
Biopesticides
and
Pollution
Prevention
Division
TO:
Lois
Rossi,
Director
Special
Review
and
Reregistration
Division
BPPD
has
compiled
a
list
of
sections
of
40
CFR
180.
that
have
been
completely
incorporated
and
subsumed
into
more
recent
sections
of
40
CFR
180.
Therefore,
these
earlier,
redundant
portions
of
the
CFR
can
be
removed
with
the
assurance
that
the
affected
tolerance
exemptions
are
being
reassessed
as
required
by
FQPA.
Two
PIP
tolerance
exemptions
are
discussed
here.

The
table
lists
the
two
viral
coat
protein
PIP
tolerance
exemptions
in
40
CFR
180.1132
that
have
been
superseded
by
40
CFR
180.1184.

Conclusion
BPPD
concludes
that
the
indicated
two
tolerance
exemptions
in
40
CFR
180.1132,
are
no
longer
necessary
to
protect
public
health,
including
infants
and
children.
These
tolerance
exemptions
are
candidates
for
tolerance
revocation
because
they
are
superseded
by
40
CFR
180.1184
and
can
be
considered
reassessed.
BPPD
is
preparing
a
revocation
rule
for
publication
in
the
Federal
Register.

Background
Viral
coat
proteins.
In
1994,
EPA
enacted
tolerance
exemptions
for
watermelon
mosaic
virus­
2
coat
protein,
for
zucchini
yellow
mosaic
virus
coat
protein,
and
for
the
genetic
material
necessary
to
produce
these
proteins
in
a
specified
squash
plant.
In
1997,
the
tolerance
exemptions
for
the
coat
proteins
and
genetic
material
were
extended
to
all
raw
agricultural
commodities
(
62
FR
44579­
82,
August
22,
1997).
In
the
course
of
extending
the
tolerance
exemptions,
all
the
supporting
data
to
justify
the
new
tolerances
were
reviewed.
Therefore,
these
two
tolerances
are
considered
reassessed.
