Chemical

List
The
Inventory
Update
Rule
(
IUR)
requires
manufacturers
of
certain
chemicals
to
report
every
four
years
information
concerning
the
manufacturing,
processing,
and
use
of
their
subject
chemical.
Chemicals
listed
at
40
CFR
710.46
(
b)(
2)
are
partially
exempt
from
this
reporting
requirement
and
do
not
report
the
processing
and
use
information
required
by
40
CFR
710.52(
c)(
4).
The
Environmental
Protection
Agency
is
adding
aluminum,
chlorodiethyl­
(

aluminum,
triethyl­
(

and
aluminum,
trichlorotrimethyldi­
(
CASRN

to
this
partial
exemption
through
a
direct
final
rulemaking
action.
The
addition
of
these
10
chemicals
results
in
a
cost
savings
of
$
135,776
to
$
146,546
in
the
first
cycle
and
$
108,621
to
$
117,237
in
future
cycles.
This
paper
provides
the
basis
for
this
conclusion.

The
non­
CBI
IUR
reporting
represents
only
a
portion
of
IUR
reporting.
Based
on
that,
EPA
assumes
25
reports
in
excess
of
300,000
pounds
would
be
received
for
these
10
chemicals.
