BASF
Corporation
has
provided
error­
only
comments
for
the
sethoxydim
preliminary
RED
and
supporting
documents
in
a
letter
dated
May
26,
2005.
In
response
to
the
error­
only
comments,
HED
has
revised
the
preliminary
risk
assessment,
the
residue
chemistry
chapter,
and
the
occupational
and
residential
chapter.
These
revised
memos
will
issued
under
the
following
DP
barcodes:
D318165,
D318169,
and
D318167
for
the
preliminary
risk
assessment,
the
residue
chemistry
chapter,
and
the
occupational
and
residential
chapter,
respectively.
HED
has
corrected
the
errors
identified
by
BASF
with
the
exception
of
minor
changes
requested
for
the
dose
levels
and
percent
active
ingredient
used
in
some
of
the
toxicology
studies.
These
changes
have
no
impact
on
the
conclusions
of
the
risk
assessment
and
would
require
revisions
of
the
supporting
DERs
and
HIARC
memo.
