MEMORANDUM
SUBJECT:
Typographical
errors
correction
TO:
Gwen
DiPietro
OSW,
HWID
FROM:
Thea

OSW,
EMRAD
The
purpose
of
this
memo
is
to
correct
the
typographical
error
discovered
in
Appendix
D
of
the
Risk
Assessment
Technical
Background
Document
for
the
Dye
and
Pigment
Hazardous
Waste
Listing
Determination,
November
11,
2003.

In
Appendix
D
on
page
D­
3,
as
cited
Table
D­
1:
Source
Model
Variable
for
Landfill,
the
minimum
dry
waste
loading
rate
is
recorded
as
1.32
Mg/
yr.
The
correct
value
is
69.16
Mg/
yr.
Note
that
this
value
must
be
multiplied
by
the
concentration
modeled
in
the
WMU
and
appropriate
unit
conversion
factors
to
obtain
the
minimum
constituent
loading
modeled
in
landfills
in
the
same
units
as
are
used
in
equation
9.5
(
i.
e.,
ConstitLoadinitial
in
kg/
yr),
as
found
in
Section
9.0
of
the
referenced
document.

This
error
reflects
a
value
used
in
earlier
modeling
runs.
The
correct
value
of
69.16
Mg/
yr
was
used
to
generate
the
loading
levels
proposed
in
the
Federal
Register.
