PREFACE
On
January
7,
2003,
the
U.
S.
Environmental
Protection
Agency
(
EPA)
promulgated
a
final
rule
amending
the
Inventory
Update
Rule
(
IUR)
(
see
40
CFR
Part
710).
Sites
affected
by
this
rule
are
subject
to
the
revised
reporting
requirements
beginning
in
2006
for
activities
conducted
during
the
2005
calendar
year.
The
first
reports
are
due
by
December
26,
2006;
sites
are
to
use
the
revised
2006
Form
U
for
reporting
to
EPA.

The
primary
goal
of
this
document
is
to
help
the
regulated
community
comply
with
the
requirements
of
the
IUR
regulations.
This
document
does
not
substitute
for
those
regulations,

nor
is
it
a
regulation
itself.
It
does
not
impose
legally
binding
requirements
on
the
regulated
community
or
on
EPA.
Determinations
regarding
compliance
with
the
IUR
requirements
will
be
based
solely
on
the
Toxic
Substances
Control
Act
15
U.
S.
C.
§
2607
and
the
IUR
regulations
(
40
CFR
Part
710).
Interested
parties
are
free
to
raise
questions
about
the
application
of
this
guidance
to
a
particular
situation.
Where
appropriate,
EPA
retains
the
discretion
to
accept
approaches
on
a
case­
by­
case
basis
that
differ
from
this
guidance,
to
the
extent
that
such
approaches
comply
with
TSCA
and
the
implementing
regulations.

document
contains

U.
S.
commerce.
This
inventory
is
called
the
TSCA
Chemical
Substance
Inventory
(
TSCA
Inventory).
In
1986,
EPA
promulgated
the
Inventory
Update
Rule
(
IUR),
also
under
TSCA
section
8(
a),
to
facilitate
the
periodic
updating
of
the
TSCA
Inventory
database
and
to
support
activities
associated
with
implementing
TSCA.
When
first
promulgated,
the
IUR
required
chemical
manufacturers
(
including
importers)
to
report
to
EPA
every
4
years
the
identity
of
chemical
substances
manufactured
(
including
imported)
annually
in
quantities
of
10,000
pounds
or
greater
at
each
plant
site
they
owned
or
controlled.
In
2003,
EPA
amended
the
IUR,
adjusting
the
universe
of
chemicals
and
plant
sites
reporting,
the
type
of
data
reported,
and
the
Confidential
Business
Information
(
CBI)
claim
procedures.

In
the
past,
EPA
has
used
the
TSCA
Inventory
and
IUR
data
to
support
many
TSCA­
related
activities
and
to
provide
overall
support
for
a
number
of
EPA
and
other
federal
health,
safety,
and
environmental
protection
activities.
In
addition
to
the
past
uses,
EPA
will
use
the
new
information
reported
in
2006
to
help
EPA,
other
agencies,
and
the
general
public
more
readily
screen
chemicals
for
exposure
and
risk.
These
reviews
will
allow
for
better
prioritization
of
chemicals
to
identify
those
warranting
more
detailed
assessments
and
to
eliminate
chemicals
of
lesser
concern
from
further
review.

This
document
updates
the
2002
guidance
manual
(
EPA
749­
B­
02­
001)
to
incorporate
the
IUR
Amendments
(
IURA)
reporting
requirements
for
2006
reporting.
Manufacturers
and
importers
of
chemical
substances
are
encouraged
to
carefully
review
the
IUR
reporting
requirements
in
40
CFR
Part
710
to
determine
whether
they
are
subject
to
these
requirements
and
what
information
is
to
be
reported.

Businesses
required
to
comply
with
the
IUR
should
have
a
thorough
understanding
of
the
TSCA
Inventory
and
the
criteria
used
to
determine
a
substance's
presence
in
the
TSCA
Inventory.
Information
on
the
scope
and
organization
of
the
TSCA
Inventory
can

introductory
pages
of
the
TSCA
Chemical

Recent
Changes
to
IUR
Reporting
Requirements
In
2003,
EPA
made
several
major
changes
to
the
IUR
reporting
requirements,
which
are
highlighted
in
Table
1­
1
and
explained
later
in
this
document.
In
addition,
Form
U
was
revised
to
incorporate
these
changes.
Appendix
A
contains
the
2006
Form
U.

1.2
Rationale
for
IUR
Changes
EPA
amended
the
IUR
on
January
7,
2003
for
three
primary
reasons:


To
tailor
the
chemical
substance
reporting
requirements
to
more
closely
match
EPA's
information
needs;


To
obtain
new
and
updated
information
concerning
potential
exposures
to
a
subset
of
chemical
substances
listed
in
the
TSCA
Inventory;
and

To
improve
the
utility
of
the
information
reported.

These
goals
are
supported
by
the
policy
in
TSCA
§
2(
b)(
1)
that
"
adequate
data
should
be
developed
with
respect
to
the
effect
of
chemical
substances
and
mixtures
on
health
and
the
environment
and
that
the
development
of
such
data
should
be
the
responsibility
of
those
who
manufacture
and
those
who
process
such
chemical
substances
and
mixtures."
EPA
believes
that
the
data
currently
available
to
EPA
are
generally
inadequate
for
risk
screening
purposes.
TSCA
§
8(
a)(
2)
authorizes
EPA
to
require
manufacturers
and
processors
of
chemical
substances
to
report
a
wide
variety
of
data,
including
exposure­
related
information
of
the
type
that
will
be
reported
for
certain
chemical
substances
under
the
revised
IUR.
The
IUR
amendments
removed
certain
reporting
requirements
and
added
others
to
allow
the
Agency
to
collect
information
that
is
most
needed
by
EPA
and
other
federal
agencies
for
screening,
assessing,
and
managing
risk.
The
availability
of
these
data
will
also
enhance
public
awareness
of
basic
information
about
chemical
substances.

The
information
collected
under
this
revised
IUR
will
enable
EPA
to
develop
a
more
systematic
and
comprehensive
approach
to
the
chemical
prioritization
process.
EPA
uses
exposure
information
in
a
wide
variety
of
analyses
and
decision­
making,
including
that
associated
with
projects
within
the
Existing
Chemicals
Program
and
Design
for
the
Environment
(
DfE).
(
Further
information
on
these
projects
can
be
found
at
http://
www.
epa.
gov/
opptintr/.)
Often
under
these
programs,
EPA
completes
an
initial
review
of
chemical
substances
to
identify
those
substances
that
raise
particular
concerns
as
to
the
potential
risks
they
present
to
human
health
and
the
environment.

Data
Use
Plan

anticipated
uses
of
the
IUR
exposure
data.

must
now
be
reported
(
40

Reporting
of
inorganic
chemical

added
For
2006
reporting,
a
partial
reporting
exemption
for
inorganic
chemical
substances
is
in
place,
i.
e.,
no
reporting
of
industrial,

as
required
based
on
production
volume
(
40
CFR
710.46(

710.57).

Reporting
changed
The
period
for
which
reporting
is
required
was
changed
from
a
corporate
fiscalyear
basis
to
a
calendar­
year
basis
(
40
CFR
710.52).

CBI
claims
for
production
volume
ranges
allowed
Submitters
can
now
claim
their
production
volume
ranges
as
CBI,
in

a
specific
production
volume
number
and
the
CBI
status
of
that
number
(
40
CFR
710.52(

v)).
This
change
allows
submitters
to
assert
a
confidentiality
claim
for
specific
production
volume
information
while
releasing
the
more
general
production
volume
range
as
public

Use
of
Exposure­
Related
Information
The
new
IUR
reporting
requirements
for
exposure­
related
information
are
related
to,
or
are
indicative
of,
three
components
of
exposure:


The
number
of
ecosystems
or
size
of
human
populations
potentially
exposed
(
e.
g.,
data
elements
concerning
number
of
sites,
number
of
workers,
and
use
in
consumer
products);


The
potential
routes,
magnitudes,
and
concentrations
of
exposures
experienced
by
the
environment
or
by
humans
(
e.
g.,
data
elements
concerning
function
of
chemical
substances
in
industrial
processes,
physical
form
of
chemical
substances,
industrial
sectors
where
chemical
substances
are
manufactured
and
used,
and
maximum
concentration);
and

The
frequency
and
duration
of
potential
exposures
(
e.
g.,
data
elements
concerning
industrial
function
categories
and
commercial
and
consumer
use
categories).

Effective
risk
screening
and
risk
management
depend
on
both
exposure
information
and
hazard
information.
The
IUR
will
provide
EPA
with
data
that
will
more
accurately
and
realistically
gauge
potential
exposure.
The
exposure­
related
information
reported
under
the
IUR
will
be
used
in
combination
with
hazard
information
such
as
that
developed
under
TSCA
section
4
test
rules
and
enforceable
consent
agreements/
orders,
through
voluntary
efforts
such
as
the
HPV
Challenge
Program,
and
other
sources.
Because
of
the
limitations
of
the
data
available
from
past
information
collections
such
as
the
one­
time
reporting
of
information
by
a
subset
of
the
manufacturers
of
a
small
number
of
selected
high
production
volume
chemicals,
as
was
included
in
EPA's
voluntary
Use
and
Exposure
Information
Project
(
UEIP),
EPA
is
collecting
the
information
necessary
to
develop
an
exposure
database.
Table
1­
2
provides
examples
of
how
the
exposure
information
will
be
used.
The
new
data
elements
included
in
the
2006
IUR
collection
improve
EPA's
ability
to
evaluate
exposure.
This
new
exposure­
related
information
will
facilitate
a
more
efficient
and
effective
screening
of
chemical
substances
based
either
on
exposure
or
on
risk.

Reporting
Requirements
This

the
reporting
requirements
for
the
2006
IUR
reporting
cycle.
Reporting
requirements
have
changed
since
the
last
IUR
reporting
cycle
in
2002.
There
are
two
things
to
consider
in
determining
your
reporting
requirements
for
each
chemical
substance
that
you
manufacture
in
the
United
States
or
import
into
the
United
States:


Is
the
substance
reportable
under
the
IUR?


Are
you
a
manufacturer
(
or
importer)
who
is
required
to
report
that
substance?

Figure

is
a
decision
tree
summarizing
the
questions
to
answer
when
determining
your
reporting
obligations
for
a
particular
substance.
Detailed
reporting
obligations
are
discussed
further
in
this
chapter.
Appendix
B
provides
definitions
of
terms
used
for
IUR
reporting.

2.1
Is
Your
Chemical
Substance
Reportable
Under
the
IUR?

A
chemical
substance
is
reportable
under
the
IUR
if
it
is
in
the
TSCA
Inventory
as
of
August
25,
2006,
and
not
be
exempt
from
reporting
under
the
IUR
(
40
CFR
710.45).
The
TSCA
Inventory
and
the
specific
exemptions
from
reporting
are
described
below.

2.1.1
Is
Your
Chemical
Substance
in
the
TSCA
Inventory?

The
following
subsections
provide
information
to
determine
if
your
chemical
substance
is
listed
in
the
TSCA
Inventory.

2.1.1.1
What
is
the
TSCA
Inventory?
Authorized
by
§
8(
b)
of
TSCA,
the
TSCA
Inventory
is
a
list
of
chemical
substances
manufactured,
imported,
or
processed
for
commercial
purposes
in
the
United
States.
The
TSCA
Inventory
was
originally
compiled
from
reports
submitted
in
1978
and
1979
by
manufacturers,
importers,
and
certain
processors
of
chemicals
in
commerce
during
those
years.
Subpart
A
of
40
CFR
Part
710
prescribes
criteria
for
including
a
substance
in
the
TSCA
Inventory.
New
chemical
substances
are
added
to
the
TSCA
Inventory
when
companies
that
have
submitted
Premanufacture
Notifications
(
PMNs)
to
EPA
under
section
5
of
TSCA
notify
EPA
that
they
have
begun
to
manufacture
or
import
the
chemical
substance
(
under
40
CFR
720.102).

2.1.1.2
How
Do
You
Determine
Whether
a
Chemical
Substance
is
Listed
on
the
TSCA
Chemical
Substance
Inventory?
The
following
methods
may
help
you
determine
if
your
chemical
substance
is
listed
in
the
TSCA
Inventory:


Locate
the
substance
in
the
Public
Inventory
(
see
Chapter
7
for
more
information);


Search
company
records
to
determine
if
the
substance
was
previously
reported
to
EPA
under
the
IUR;


Search
company
records
for
a
PMN
or
other
communication
that
confirmed
with
EPA
the
substance
was
in
the
TSCA
Inventory;
and

Search
company
records
for
a
Notice
of
Commencement
of
manufacture
or
import
for
a
PMN
substance
that
was
submitted
to
EPA.

Several
commercial
databases
have
incorporated
the
Public
Inventory
(
which
excludes
substances
with
confidential
identities)
and
indicate
whether
a
given
chemical
substance
is
included
in
the
TSCA
Inventory.
Because
these
databases
are
not
generated
or
peer­
reviewed
by
EPA,
the
Agency
cannot
guarantee
the
accuracy
of
the
information
in
these
databases.
Thus,
there
is
no
penalty
for
reporting
a
substance
that
may
be
listed
on
a
commercial
database,
but
is
not
required
to
be
reported.
However,
if
a
commercial
database
that
you
use
fails
to
include
all
reportable
chemicals
and,
as
a
result,
you
fail
to
report
information
for
these
chemicals,
you
may
be
in
violation
of
TSCA
(
40
CFR
710.1(
c)).
Please
note
that
hydrates
are
not
listed
in
the
TSCA
Inventory;
however,
you
are
required
to
report
the
CAS
registry
number
of
the
corresponding
anhydrous
form
(
40
CFR
710.3).
You
should
adjust
the
reported
production
volume
to
exclude
water.

For
example,
Company
A
manufactures
50,000
pounds
of
copper
(
II)
sulfate
pentahydrate,
CuSO
4

5H
2
O.
This
chemical
should
be
reported
under
the
anhydrous
form
of
copper
(
II)
sulfate,
CuSO
4.
To
calculate
the
production
volume,
multiply
the
mass
of
hydrated
compound
by
the
weight
fraction
(
ratio
of
molecular
weights)
of
anhydrous
copper
(
II)
sulfate,
CuSO
4,
in
the
hydrated
copper
(
II)
sulfate,
CuSO

The
molecular
weights
of
CuSO

and
CuSO

O
are
159.6
pounds
per
pound­
mole
and
249.7
pounds

respectively.
Company
A
should
report
31,958
pounds
of
anhydrous
copper
(
II)
sulfate
on
Form

based
on
the
following
calculation:

to
determine
whether
the

is
listed.
Because
searches
of

are
labor­
intensive,
you
are
urged
to
request
such
a
search
only
if
your
search
of
the

for
you
to
complete
the

period.

In
communicating
with
EPA,
you
must
substantiate
the
fact
that
you
are
manufacturing
or
importing
the
substance
in
question
by
providing
the
following
information
(
40
CFR
720.25):


Company

that
your

pursuant
to
the
IUR;
and

An

If
you
assert
that
any
of
the

you
must
clearly
identify
the

carefully
to
ensure
that
the
information
in

falls
within
the
protection
of
TSCA
section

as
CBI,
EPA
recommends
that
you
place
your
letter
and
any
accompanying
materials
in
a
double­
wrapped
package
for
maximum
security.
The
inner
wrapper
should
be

and
address
of
the
recipient
and
your
return
address.
Nothing
on
the
outer
wrapper
should
indicate
that
the
package
contains
CBI.
This
package
should
be
sent
to

Regular
first
class
mail
should
never
be
used
to
send
CBI
to
EPA.
Failure
to
follow
proper
procedures
regarding
CBI
materials
may
result
in
EPA
making
the
information
available
to
the
public
without
further
notice
to
you.

After
processing
your
response,
EPA
will
inform
you
whether
the
chemical
substance
is
in
the
TSCA
Inventory
and
whether
the
substance
is
subject
to
reporting
under
the
IUR.
If
the
chemical
substance
is
found
on
the
confidential
TSCA
Inventory,
EPA
will
notify
the
person(
s)
who
originally
reported
the
substance
that
another
person
has
requested
information
pursuant
to
the
IUR
procedures
and
was
told
that
the
chemical
substance
is
in
the
TSCA
Inventory
and
that
it
is
subject
to
reporting.
Your
identity
will
not
be
revealed
to
the
person
originally
reporting
the
substance.

If
you
are
an
importer
and
cannot
provide
all
of
the
required
information
because
your
foreign
manufacturer/
supplier
is
maintaining
it
as
confidential,
the
manufacturer/
supplier
can
send
the
information
directly
to
EPA.
Be
advised
that
it
is
the
obligation
of
the
importer
to
ensure
that
the
foreign
manufacturer
complies
with
the
IUR
requirements
(
40
CFR
720.25(
b)).

2.1.2
Is
Your
Chemical
Substance
Excluded
from
Reporting?

Four
categories
of
substances,
though
included
in
the
TSCA
Inventory,
are
largely
excluded
from
reporting
under
the
IUR.
These
categories
are
polymers,
certain
natural
gas
streams,
microorganisms,
and
naturally
occurring
substances.
Refer
to
section
710.46
of

submitters
are
responsible
for
verifying
exemptions.
If
a
substance
does
not
bear
an
"

flag
and
section
710.46
of
the

2.1.2.1
Polymers.
Polymers
are
exempt
from
IUR
reporting.
The
IUR
definition
of
polymer
is
sufficiently
broad
to
include
virtually
all
those
substances
that
are
generally
considered
polymers.
These
include
siloxanes
and
silicones,
rubber,
lignin,
polysaccharides
(
such
as
starch
and
gums),
proteins
(
such
as
gelatin
and
hemoglobin),
and
enzymes.
However,
substances
that
result
from
hydrolysis,
depolymerization,
or
chemical
modification,
regardless
of
the
extent
of
these
processes,
of
polymers
so
that
the
final
products
are
no
longer
polymeric
(
e.
g.,
a
mixture
of
amino
acids
that
is
the
result
of
hydrolysis
of
a
polypeptide)
are
not
considered
to
be
polymers
and
must
be
reported
if
not
otherwise
excluded
(
40
CFR
710.46(
a)(
1)).
For
reporting
purposes,
salts
of
polymers
are
also
considered
to
be
polymers.
Please
note
that
a
few
of
the
polymerization
gases
that
are
not
considered
polymers
might
have
been
incorrectly
flagged
with
"
XU"
because
of
the
inclusion
of
the
word
fragment
"
polym"
in
the
chemical
name.
These
substances
are
reportable
under
the
IUR.
See
40
CFR
710.46(
a)(
1)
for
the
regulatory
definition
of
polymers.

2.1.2.2
Microorganisms.
Microorganisms
are
exempt
from
IUR
reporting.
A
microorganism
is
any
combination
of
chemical
substances
that
is
a
living
organism
and
that
meets
the
definition
of
"
microorganism"
at
40
CFR
725.3.
Any
chemical
substance
produced
from
a
living
microorganism
is
reportable
unless
otherwise
excluded
(
40
CFR
710.46(
a)(
2)).

2.1.2.3
Natural
Gases.
Table

identifies
certain

of
natural
gas
that
are
exempt
from
IUR
reporting;
the
natural
gas
exemption
is
new
for
the
2006
reporting
cycle.
EPA
believes
that
adequate
IUR
information
has
been
collected
on
these
chemical
substances
to
date
to
fulfill
EPA's
current
needs
and
the
needs
of
other

Naturally
Occurring
Substances.
Chemical
substances
that
are
described
in
40
CFR
710.4(
b)
of
the
TSCA
Inventory
Reporting
Regulations
are
considered
"
naturally
occurring"
and
are
automatically
on
the
TSCA
Inventory
but
are
not
reportable
under
IUR.
Examples
of
substances
that
are
typically
naturally
occurring
materials
are
raw
agricultural
commodities,
water,
air,
natural
gas,
crude
oil,
rocks,
ores,
and
minerals.
However,
since
the
section
710.4(
b)
exclusion
is
a
process­
specific
exclusion
rather
than
a
chemical­
specific
one,
if
you
produce
any
substance
in
a
manner
other
than
as
described
in
section
710.4(
b),
you
are
required
to
report
unless
otherwise
excluded
(
40
CFR
710.46(
a)(
3)).
For
this
reason
minerals
and
certain
agricultural
products
are
sometimes
considered
not
to
be
naturally
occurring
because
of
their
method
of
production.

Further,
section
710.46(
a)(
3)
intentionally
exempts
from
IUR
reporting
any
chemical
substance
that
is
isolated/
removed
from
nature
for
a
commercial
purpose
by
the
means
specified
in
section
710.4(
b).
It
also
exempts
any
other
chemical
substance
derived
or
separated
from
the
substance
originally
removed
from
nature,
provided
such
derivation
involved
only
the
means
specified
in
that
section
(
e.
g.,
being
obtained
by
aqueous
extraction
or
flotation
or
by
pressing).
Whether
a
substance
is
considered
"
naturally
occurring"
depends
on
the
manner
in
which
it
is
produced
and
isolated.
Table
2­
2
presents
some
examples
of
evaluating
the
naturally
occurring
substance
exemption.

Table
2­
2.
Examples
of
Evaluating
Substances
for
the
Naturally
Occurring
Exemption
!

Calcined
clays
that
are
formed
by
heating
naturally
occurring
clay
must
be
reported
because
such
heating
is
not
done
solely
to
remove
water;
a
chemical
change
is
primarily
intended
(
40
CFR
710.4(
b)).

!

The
naturally
occurring
substance
category
contains
only
those
substances
that
are
removed/
isolated
from
nature
essentially
by
physical
or
natural
means.
Using
water
to
extract
a
chemical
substance
from
a
naturally
occurring
substance
is
considered
a

However,
using
any

!

In
an
electrostatic
separation,
small
particles
are
removed
from
a
liquid
or
gas
stream.
The
process
is
essentially
analogous
to
a
filtration
or
gravitational
separation.
Substances
that
are
processed
by
this
means
fall
within
the
naturally
occurring
substances
category
(
40
CFR
710.4(
b)).

!

The
mining
of
coal
is
included
in
the
naturally
occurring
chemical
substances
category.
However,
heating
coal
to
produce
light
oils
or
other
chemical
substances
is
not
included
in
this
category
and
must
be
reported
(
40
CFR
710.4(
b)).

!

Ammonia
and
nitric
acid
are
generally
produced
by
chemical
synthesis
and
are,
therefore,
not
considered
naturally
occurring
(

When
Must
You
Still
Report
an
Excluded
Substance?

With
the
exception
of
naturally
occurring
substances,
a
chemical
substance
that
falls
into
one
of
the
excluded
categories
must
still
be
reported
if
it
is
the
subject
of
any
of
the
following:
a
rule
proposed
or
promulgated
under
sections
4,
5(

that
has
been
granted
under
a

(
40
CFR
710.46).
Appendix
C
lists
the
chemical
substances
that
fall
into
these
categories.
However,
if
you
are
unable
to
determine
whether
the
specific
chemical
substance
you
manufacture
or
import
is
listed
in
Appendix
C,
you
can
contact
EPA
to
see
if
the
specific
substance
is
reportable
(
see
Chapter
8
for
contact
information).

If
you
qualify
as
a
small
manufacturer
(
see
Section
2.2.1),
you
must
still
report
if
you
produce
25,000
pounds
or
more
in
a
year
of
a
reportable
substance
that
is
the

Chemical
Substances
Subject

When
checking
the
chemical
substances
you
manufacture
or

against
the
TSCA
Inventory,
you
may
discover
that
you
are
manufacturing
or
importing
substances
that
are
not
in
the
TSCA
Inventory
but
should
be
listed.
Such
manufacture
or
importation
is
in
violation
of
section
15
of
TSCA
and
could
subject
you
to
administrative
or
criminal
penalties.
Similarly,
if
you
are
manufacturing
or
importing
a
substance
that
was
previously
in
the
TSCA
Inventory
but
has
subsequently
been
delisted,
then
you
are
also
in
violation
of
section
15
of
TSCA.
If
either
of
these
situations
applies
to
you,
you
should
send
a

Small
manufacturers
are
still
required
to
report
on
substances
subject
to
a

proposed
or
promulgated
under
certain
sections
of
TSCA.
See
Section
2.1.3
for

2.2
Are
You
a
Manufacturer
Who
Is
Required
to
Report?

Even
if
you
manufacture
(
including
companies
that
manufacture
solely
for
export)
or
import
a
chemical
substance
reportable
under
the
IUR,
you
may
be
exempt
from
the
reporting
requirements
for
that
substance.
To
determine
whether
you
must
report,
you
should
answer
the
following
three
questions:


Do
you
qualify
as
a
small
manufacturer
with
respect
to
the
chemical
substance?


Did
you
manufacture
or
import
25,000
pounds
or
more
of
the
reportable
substance
at
any
single
site
during
the
reporting
year
(
e.
g.,
during
2005)?


Did
you
manufacture
or
import
the
reportable
substance
under
circumstances
that
do
not
require
reporting
(
e.
g.,
considering
other
reporting
exemptions)?

2.2.1
Are
You
a
Small
Manufacturer?

Small
manufacturers
(
including
both
manufacturers
and
importers)
are
usually
exempt
from
reporting
under
the
IUR.
Small
manufacturers
are
still
required
to
report
on
substances
subject
to
a
rule
proposed
or
promulgated
under
certain
sections
of
TSCA.
See
Section
2.1.3
for
more
details.
You
qualify
as
a
small
manufacturer
if
you
meet
either
one
of
the
following
criteria:


Your
total
annual
sales,
combined
with
those
of
your
parent
company,
domestic
or
foreign
(
if
any),
do
not
exceed
$
4
million
regardless
of
annual
production
volume
(
40
CFR
704.3);
or

Your
total
annual
sales,
combined
with
those
of
your
parent
company,
domestic
or
foreign
(
if
any),
are
less
than
$
40
million
for
those
plant
sites
at
which
annual
production
volume
of
that
substance
does
not
exceed
100,000
pounds
(
40
CFR
704.3).
If
the
annual
production
volume
of
the
substance
at
any
of
your
sites
is
over
100,000
pounds,
you
are
required
to
report
only
for
those
sites.
Note
that
it
is
possible
to
qualify
as
a
small
manufacturer
with
respect
to
some
substances
and
not
others
or
with
respect
to
some
plant
sites
and
not
others.

2.2.2
Do
You
Manufacture
the
Chemical
in
Quantities
of
25,000
Pounds
or
More?

Unless
you
are
a
small
manufacturer
as
described
in
Section
2.2.1,
if
you
manufactured
(
including
imported)
25,000
pounds

more
of
a
reportable
chemical
substance
at
any
single
site
you
owned

any
given
time
during
calendar
year
2005,
you
are
subject
to

Manufacture
means
to
import,
produce,
or
manufacture
with
the
purpose
of
obtaining
an
immediate
or
eventual
commercial
advantage.
This
includes,
for
example,
manufacturing
or
importing
any

of
a
chemical
substance
for
commercial
distribution
(
including
test
marketing)
or
for
use
by

2.2.2.1
Meeting
the
25,000­
Pound
Annual

You
must
report
a
chemical
substance
only
if
you
manufactured
(
including
imported)
25,000
pounds
or
more
of
the
substance
at
any
single
site
you
owned
or
controlled
during
the
calendar
year
immediately
preceding
the
submission
period.
Moreover,
if
during
the
year
you
manufactured
25,000
pounds
or
more
of
the
substance
at
some
sites
and
less
than
25,000
pounds
at
other
sites,
you
will
need
to
report
the
substance
only
for
those
sites
at
which
you
manufactured
(
including
imported)
25,000
pounds
or
more
(
40
CFR
710.48).
Some
companies
may
both
manufacture
and
import
the
same
substance.
These
companies
should
add
together
the
manufacturing
and
importation
volumes
at
each
site
to
determine
whether
they
exceed
the
25,000­
pound
threshold,
based
on
the
definition
of
manufacture.

In
many
cases,
reportable
substances
are
contained
within
a
mixture.
Although
mixtures
are
not
reportable,
the
chemical
substances
making
up
a
mixture
are
reportable
(
40
CFR
710.3).
If
you
manufacture
the
substances
as
part
of
a
mixture,
you
should
determine
whether
the
production
volume
for
each
substance
in
the
mixture
was
over
25,000
pounds.
Similarly,
if
you
import
a
mixture,
you
should
determine
whether
its
importation
volume
for
each
substance
in
the
mixture
is
25,000
pounds
or
more.
Note,
however,
that
a
person
who
produces
a
mixture
by
combining
existing
substances
without
a
chemical
reaction
is
not
a
manufacturer
of
those
substances
and,
therefore,
does
not
have
to
report
those
substances
under
the
IUR.

2.2.3
Do
You
Qualify
for
Any
Additional
Reporting
Exemptions?

If
you
manufacture
or
import
reportable
substances
under
the
following
circumstances,
you
are
not
required
to
report
for
those
substances
under
the
IUR:


The
chemical
substance
is
imported
as
an
article
or
part
of
an
article.
An
article
is
defined
in
40
CFR
710.3(
d)
as
"
a
manufactured
item
(
1)
which
is
formed
to
a
specific
shape
or
design
during
manufacture,
(
2)
which
has
end­
use
function(
s)
dependent
in
whole
or
in
part
upon
its
shape
or
design
during
end
use,
and
(
3)
which
has
either
no
change
of
chemical
composition
during
its
end
use
or
only
those
changes
resulting
in
compositions
which
have
no
commercial
purpose
separate
from
that
of
the
article
and
that
may
occur
as
described
in
section
710.4(
d)(
5),
except
that
fluids
and
particles
are
not
considered
articles
regardless
of
shape
or
design."
EPA
considers
imported
items
as
articles
if
they
are
manufactured
in
a
specific
shape
or
design
for
a
particular
end­
use
application
and

Chapter

this
design
is
maintained
as
an
essential
feature
in
the
finished
product.
Thus,
EPA
views
materials
such
as
metal
or
plastic
sheets,
wire,
coated
fabric,
rolled
carpet,
sheets
of
plywood,
and
other
similar
materials
as
articles,
even
if,
for
example,
subsequent
to
import
they
are
rolled
or
drawn
thinner,
cut,
printed,
laminated,
or
thermoformed,
so
long
as
they
meet
the
above
criteria.
Substances
that
are
part
of
such
articles
are
not
subject
to
reporting
under
the
IUR.
If
an
item
is
manufactured
in
a
particular
shape
for
the
purpose
of
shipping
convenience
and
the
shape
has
no
function
in
the
end
use,
it
would
not
be
considered
an
article.
Thus,
chemical
substances
that
are
part
of
items
such
as
metal
ingots,
billets,
and
blooms
are
subject
to
reporting
under
the
IUR.


The
chemical
substance
is
manufactured
as
an
impurity,
by­
product,
or
nonisolated
intermediate.
Sections
40
CFR
710.3(
d),
40
CFR
710.23,
and
40
CFR
720.30(
g)
provide
the
regulatory
definitions
of
these
terms.


If
between
August
25,
2005,
and
August
24,
2006,
you
submitted
the
information
required
by
the
IUR
in
response
to
another
rule
promulgated
under
TSCA,
such
as
the
Preliminary
Assessment
Information

Subpart
B,
you
are
not
required
to

Chemical
X
never
leaves
Reactors
1
or
2
without
being
reacted.
Company
A
does
not
need
to
report
a
Form
U
for
Chemical
X
because
it
is
considered
to
be
a
non­
isolated
intermediate
and
is
therefore
fully
exempt.

Company
B
manufactures
400,000
pounds
of
a
chemical
intermediate
called
Chemical
Y
during
the
production
of
a

polymer,
at
which
point
Chemical
Y
is
destroyed.
Chemical
Y
never
leaves
this
production
site.
Company
B
is
required
to
report
Chemical
Y
because
the

isolated"
Chemical
Y.

Company
C
imports
10,000,000
pounds
of
Chemical
Z
in
the
form
of
thin
sheets.
Company
C
cuts
these
sheets
into
the
desired
size
and
shape,
which
is
sold
to
consumers.
Company
C
is
not
required
to
report
Chemical
Z
because
it
is
considered
to
be
an
article
and
therefore
exempt
from
reporting.

Is
Over
300,000
Pounds?

If
you
produce
300,000
pounds
or
more
in
calendar
year
2005
of
a
reportable

Three
categories
of
substances
are
exempt
from
this
reporting
requirement.
Manufacturers
and
importers
of
certain
petroleum
process
streams,
regardless
of
the
production
volume,
are
partially
exempt
and
do
not
need
to
complete
Part
III
of
Form
U
for
these
substances.
EPA
created
a
partial
exemption
for
specific
chemical
substances
where
EPA
has
identified
that
there
is
a
low
current
interest
in
the
IUR
processing
and
use
information
related
to
the
chemical.
For
the
2006

Chemical
Identifying

currently
requires
manufacturers
(

to
report
both
the
specific
chemical
substance
name
and
the
CAS
Registry
Number
(

manufactured
(
including
imported)
in
amounts
over
25,000
pounds
per

(
40

You
may
claim
the
identity
of
a
substance
that
is
listed
as
confidential
on
the
TSCA
Inventory
as
confidential
by
checking
the
CBI
box.
EPA
will
not
honor
a
chemical

CBI
claim
for
a
substance
that
is
listed
on
the
nonconfidential
Public

No
CBI
claim
for
chemical
identity
will
be
accepted
unless
accompanied
by
a
separate
written
substantiation
for
each
chemical
substance
claimed
as
CBI;
see
Section

4.5.1.1
CAS

and
Other
Identifying

Every
chemical
substance
reported
on
Form
U
must
be
accompanied
by
its
CAS
Registry
Number
(
entered
into
Block
1.1
of
Part

or
other
identifying
number
(
40
CFR
710.52(

The
printed
edition
of
the
TSCA
Inventory
contains
detailed
instructions
on
how
to
locate
the
CAS
Registry
Number
for
a
substance
listed.
When
you
report
a
CAS
Registry
Number,
please
verify
that
the
number
you
are
reporting
is
the
correct
number
for
your
substance.

The
CAS
Registry
Number
is
the
preferred
identifier
for
chemical
substances
being
reported
as
part
of
the
IUR.
If
you
are
unable
to
find
a
CAS
Registry
Number
in
the
Public
Inventory,
then
the
substance
was
not
in
the
TSCA
Inventory
as
of
the
date
of
printing
or
the
substance
is
listed
as
confidential
(
in
which
case
the
specific
identity
is
not
listed
and
the
chemical
substance
has
an
Accession
Number
rather
than
a
CAS
Registry
Number).
If
this
is
the
case,
you
can
use
one
of
the
following
acceptable
identifying
numbers:


EPA
Accession
Number;
or

PMN
Number.

EPA
Accession
Number.
If
the
identity
of
a
chemical
substance
in
the
TSCA
Inventory
is
confidential,
the
printed
Inventory
lists
an
Accession
Number
for
that
substance
and
uses
a
generic
name
rather
than
a
specific
identity.
You
can
use
an
Accession
Number
as
an
identifying
number
only
if
EPA
has
communicated
the
appropriate
Accession
Number
to
you
(
e.
g.,
following
your
report
for
the
original
Inventory
in
1978
or
1979,
or
following
commencement
of
manufacture
or
import
of
a
substance
for
which
you
filed
a
PMN).
You
may
be
reporting
for
the
wrong
substance
if
you
find
a
generic
chemical
identity
in
the
printed
Inventory
that
you
think
belongs
to
your
substance
and
report
using
the
Accession
Number
that
pertains
to
that
substance.
An
Accession
Number
may
not
be
used
for
a
nonconfidential
chemical
substance.
A
typical
Accession
Number
is
a
5­
digit
number
such
as
"
29735."

PMN
Number.
If
you
filed
a
PMN
for
a
substance
that
is
now
reportable
under
the
IUR
and
that
PMN
was
assigned
a
PMN
number,
you
can
use
that
as
an
identifying
number.
A
typical
PMN
number
looks
like
this:
"
P­
85­
0243"
or
"
P­
83­
0001A."

Please
be
aware
that
a
chemical
substance
that
has
a
PMN
number
is
not
automatically
reportable
under
the
IUR.
A
PMN
substance
is
reportable
under
the
IUR
only
if
it
is
included
in
the
TSCA
Inventory.
A
PMN
substance
is
included
in
the
TSCA
Inventory
only
if
a
Notice
of
Commencement
was
received
by
EPA
for
the
substance.

If
you
manufacture
the
chemical
substance
at
the
plant
site
identified
and
do
not
distribute
the
chemical
substance
or
any
mixture
containing
that

for
commercial
purposes,
enter
"
Y"
in
the

next
to
the
CBI
box.
Otherwise,
enter
"
N."
Note:
you
cannot
report
an
imported
chemical
substance
as
site­
limited
(
40
CFR
710.43).
To
claim
this
information
as
confidential
for
the
substance,
enter
"
X"
in
the
CBI
box.
You
may
claim
the
fact
that
a

is
not
site­
limited
as
confidential,
if
appropriate.

4.6.4
Activity
(
Manufacture
and/
or
Import)
(
Part

Block
2.4)

If
you
manufacture
the
substance,
enter
"
M"
in
the
Activity
box;
enter
"

Activity
box.
Check
the
CBI
box
to
claim
the
nature
of
the
activity
(
i.
e.,
manufacture
vs.
importation)
as
confidential
for
the
substance.
Claiming
activity
as
CBI
does
not
protect
the
link
between
your
company
and
the
substance;
that
link
will
not
be
protected
unless
you
check
the
CBI
box
next

volumes
together
and
report
the
total
volume
(
40
CFR
710.52(
c)(
3)(

Report
the
quantity
to
at
least
two
significant
figures;
it
should
be
accurate
to
the
extent
known
or
reasonably
ascertainable
by
you.
Production
volumes
should
be
reported
in
numeric
format
(
i.
e.,
50,000
or
6,352,000)
since
the
Agency's
automated
equipment
cannot
read
volumes
other
than
numeric
format.
For
example,"
2

are
not
acceptable,
nor
are
abbreviations
such
as
M
(
12,000,000

or
K
(
50,000

to
claim
production
volume
as

4.6.6
Production
Volume
Range
(
Part

4.6.7
Number
of
Workers
(
Part
II,
Block
2.7)

EPA
requires
that
you
report
your
estimate
of
the
total
number
of
workers
reasonably
likely
to
be
exposed
to
the
chemical
substance
at
each
reporting
site
(
40
CFR
710.52(
c)(
3)(
vi)).
For
Block
2.7,
report
the
total
number
of
workers
reasonably
likely
to
be
exposed
at
the
manufacturing
site.
For
each
substance,
report
the
range
code
that
corresponds
to
the
appropriate
number
of
workers
as
shown
in
Table
4­
3.
When
an
import
site
aggregates
and
reports
the
quantity
of
chemical
imported,
the
administrative
site
should
likewise
aggregate
and
report
the
number
of
exposed
workers.
For
imported
substances,
your
site
may
not
have
any
workers
reasonably
likely
to
be
exposed.
You
should
report
code
W1
to
reflect
fewer
than
ten
workers
exposed.

EPA
defines
"
reasonably
likely
to
be
exposed"
as
an
exposure
to
a
chemical
substance
that,
under
foreseeable
conditions
of
manufacture,
processing,
distribution
in
commerce,
or
use
of
the
chemical
substance,
is
more
likely
to
occur
than
not
to
occur
(
40
CFR
710.43).
Such
exposures
during
manufacturing
would
normally
include,
but
not
be
limited
to:
charging
reactor
vessels;
drumming;
bulk
loading;
cleaning
equipment;
maintenance
operations;
materials
handling
and
transfers;
sampling;
and
analytical
operations.
Covered
exposures
include
exposures
through
any
route
of
entry
(
inhalation,
ingestion,
skin
contact
or
absorption,
etc.),
but
exclude
accidental
exposures.
Workers
that
would
be
exposed
if
not
for
the
use
of
personal
protective
equipment
and
engineering
controls
should
be
included
in
the
reported
estimate.
For
example,
if
a
worker
wears
a
dust
mask
and
gloves
while
handling
a
powdered
chemical
substance,
then
that
worker
should
be
reported
as
a
worker
reasonably
likely
to
be
exposed.
Check

CBI
box
to
claim
the
number
of
workers
as
confidential.

volume
that
is
attributable
to
each
unique
combination
of
process/

code,
NAICS
code,
and

The
quantity
should
be
accurate
to

obtainable
by
you.
Round
the

to
the
nearest
10

5
percent
or
less
of
the
total

volume
of
a

to
0
percent
if
the

is
greater
than
or
equal
to
300,000
pounds
(
40
CFR
710.52(
c)(

In
such
cases,
you
must
report
the
percentage
of
production
volume
attributable
to
that
combination
to
the
nearest
1
percent
of
production
volume
(
40

This
exception
to
the
general
rounding
rule
is
to
ensure
that
adequate
use
information
is
reported
for
gross

The
total
percentage
of
production
volumes
associated
with
the
NAICS
code/

may
add
up

your
estimate
of
the
total
number
of
workers,
including
those
at
sites
not
under
your
control,
that
are
reasonably
likely
to

exposed
to
the
chemical
substance
at
facilities
that

the
substance
in
a
manner
that
corresponds
to
each
unique
combination
of
process/
use
code,
NAICS
code,
and
IFC
code
(
40
CFR
710.52(
c)(

You
need
only
report
this
information
to
the
extent
that
it
is
readily
obtainable.
For
each
substance,
report
the
range
code
listed
in
Table
4­
9
that
corresponds
to
the
appropriate
number
of
workers.

EPA
defines
"
reasonably
likely
to
be
exposed"
as
an
exposure
to
a
chemical
substance
under
foreseeable
conditions
of
manufacture,
processing,
distribution
in
commerce,
or
use
of
the
chemical
substance
(
40
CFR
710.43).
Such
exposures
would
normally
include,
but
not
be
limited
to:
charging
reactor
vessels;
drumming;
bulk
loading;
cleaning
equipment;
maintenance
operations;
materials
handling
and
transfers;
sampling;
and
analytical
operations.
Such
exposures
during
industrial
uses
could
include,
but
not
be
limited
to,
spray
applications
of
the
chemical
(
paints,
coatings,
etc.)
and
misting
during
roll
coating/
printing.
Covered
exposures
include
exposures
through
any
route
of
entry
(
inhalation,
ingestion,
skin
contact
or
absorption,
etc.),
but
exclude
accidental
exposures.
Workers
that
would
be
exposed
if
not
for
the
use
of
personal
protective
equipment
and
engineering
controls
should
be
included
in
the
reported
estimate.
For
example,
if
a
worker
wears
a
dust
mask
and
gloves
while
handling
a
powdered
chemical
substance,
then
that
worker
should
be
reported
as
a
worker
reasonably
likely
to
be
exposed.

a
product
that
is
specifically
intended
for
use
by
children
age
14

children
when
you
answer
"
yes"
to
at
least
one
of
the
following
questions
for
the
product
into
which
your
chemical
substance
or
mixture
is
incorporated:
(
1)
Is
the
product
commonly
recognized
(
i.
e.,
by
a
reasonable
person)
as
being
intended
for
children
age
14
or
younger;
(
2)
Does
the
manufacturer
of
the
product
state
through
product
labeling
or
other
written
materials
that
the
product
is
intended
or
will
be
used
by
children
age
14
or

or
(
3)
Is
the
advertising,
promotion,
or
marketing
of
the
product
aimed
at
children
age
14
or
younger?
Using
this
definition,
if
you
determine,
based
on
readily
obtainable
information,
that
your
chemical
substance
or
mixture
is
used
in
a
product
that
is
intended
to
be
used

How
to
Assert
Confidentiality
Claims
Under
the
proper
circumstances,
information
submitted
to
EPA
under
the
IUR
can
be
claimed
confidential.
However,
such
claims
will
not
be
accepted
and
honored
if
they
are
not
asserted
at
the
time
information
is
submitted
to
EPA
or
if
they
are
submitted
in
a
manner
inconsistent
with
the
rule
and
reporting
instructions.

You
can
claim
certain
information
submitted
to
EPA
under
this
rule
as
confidential
if
you
believe
that
doing
so
is
warranted
under
the
substantive
criteria
for
determining
confidentiality
found
within
40
CFR
2.208.
EPA's
procedures
for
processing
and
reviewing
confidentiality
claims
are
set
forth
at
40
CFR
Part
2,
Subpart
B.
EPA
strongly
encourages
you
to
review
confidentiality
claims
carefully
to
ensure
that
the
information
in
question
falls
under
the
protection
of
TSCA
section
14
and
fully
meets
the
substantive
criteria
within
the
Part
2
regulations
referred
to
above.

To
claim
information
as
confidential,
you
must
check
the
appropriate
boxes
on
Form
U
and
have
an
authorized
official
sign
the
certification
statement
on
the
reporting
form
(
40
CFR
710.58(
a)).
If
you
fail
to
do
so,
EPA
could
release
the
information
to
the
public
without
further
notice
to
you.
As
reflected
in
the
regulations,
by
signing
the
certification
statement
you
certify
that
your
claims
of
confidentiality
are
made
in
good
faith.
Procedures
for
claiming
information
submitted
electronically
(
such
as
a
submission
on
diskette)
as
confidential
are
specified
in
Chapter
6.
CBI
must
not
be
submitted
by
e­
mail.
See
Section
2.1.1.3
for
CBI
packaging
instructions.

Specific
procedures
for
CBI
claims
of
chemical
identity,
manufacturing
plant
and
plant
site
information,
and
chemical
production
volume
information
are
addressed
below.

5.1
Chemical
Identity
You
may
assert
a
confidentiality
claim
for
the
specific
identity
of
a
chemical
substance
only
if
EPA
treats
that
substance
identity
as
confidential
in
the
TSCA
Inventory
at
the
time
your
report
is
submitted
(
i.
e.,
the
substance
is
not
on
the
Public
Inventory)
(
40
CFR
710.58(
b)).
Both
confidential
and
nonconfidential
substances
can
be
included
in
the
same
submission.
Confidential
substances
can
be
included
in
diskette
submissions
(
see
Chapter
6
for
further
discussion
of
diskette
submission
procedures).

A
claim
of
confidentiality
for
the
identity
of
a
chemical
will
not
be
accepted
unless
accompanied
by
a
separate
written
substantiation
for
each
chemical
substance
claimed
as
CBI.
To
assert
a
claim
of
confidentiality
for
the
identity
of
a
reportable
chemical
substance,
you
must
submit
detailed
written
answers
to
the
questions
at
40
CFR
710.58(
b)(
1),
which
are
repeated
in
DRAFT:
Chapter
5.0
How
to
Assert
Confidentiality
Claims
5­
2
Table
5­
1.
In
addition,
an
authorized
official
from
your
company
must
sign
and
date
Form
U.
The
answers
must
be
complete
and
specific
to
the
chemical
substance
in
question.
If
any
of
the
information
contained
in
the
answers
to
these
questions
is
asserted
to
contain
CBI,
you
must
clearly
identify
the
information
that
is
claimed
confidential
by
marking
the
specific
information
on
each
page
with
a
label
such
as
"
confidential
business
information,"
"
proprietary,"
or
"
trade
secret"
(
40
CFR
720.25).
If
the
required
substantiation
does
not
accompany
your
Form
U,
EPA
may
make
the
chemical
identities
reported
on
the
form
available
to
the
public
without
further
notice
to
you.
See
Section
2.1.1.3
for
CBI
packing
instructions.

If
you
are
manufacturing
or
importing
a
chemical
substance
that
is
currently
listed
in
the
TSCA
Inventory
as
confidential,
you
are
encouraged
not
to
assert
confidentiality
claims
if
circumstances
are
now
such
that
confidentiality
is
no
longer
necessary.
If
you
report
a
previously
confidential
substance
as
nonconfidential,
that
substance
will
subsequently
be
listed
in
the
TSCA
Inventory
as
nonconfidential.

5.2
Manufacturing
Plant
Site
Identity
Under
the
IUR,
you
may
assert
a
claim
of
confidentiality
for
the
identity
of
the
manufacturing
facility
if
release
of
that
identity
would
reveal
confidential
business
information
as
contemplated
under
Section
14
of
TSCA.
EPA
believes
claims
for
CBI
should
be
limited
to
circumstances
in
which
they
are
absolutely
necessary
and
legally
justified.

To
assert
a
claim
of
confidentiality,
you
are
required
to
check
the
CBI
box
at
block
2.2
of
Part
II
on
the
reporting
form
indicating
a
confidentiality
claim
for
plant
site
identity
information
and
you
are
required
to
substantiate
that
claim
(
40
CFR
710.58(
c)).
To
do
this,
you
must
submit
with
Form
U
detailed
written
answers
to
the
two
questions
at
40
CFR
710.58(
c)(
1),
which
are
also
listed
in
Table
5­
2.
In
addition,
an
authorized
official
from
your
company
must
sign
and
date
Form
U
(
40
CFR
710.58(
c)(
1)).
This
upfront
substantiation
is
not
required
for
company
information
CBI
claims
(
block
2.1
on
Form
U).
Please
note
that
both
plant
site
and
company
information
claims
are
to
be
made
in
conjunction
with
a
specific
chemical
substance
on
page
2
of
Form
U.
For
instance,
if
you
report
four
chemical
substances
on
one
Form
U
(
by
photocopying
additional
pages
of
Part
II
and
III)
you
are
able
to
claim
CBI
for
plant
site
identity
for
one
chemical
while
releasing
information
for
the
other
three.

Questions
To
Be
Answered
When
Making
Plant
Site
Identity
CBI
Claims
No.
Question
1.
Has
site
information
been
linked
with
a
chemical
identity
in
any
other
Federal,
state,
or
local
reporting
scheme?
For
example,
is
the
chemical
identity
linked
to
a
facility
in
a
filing
under
the
EPCRA
section
311,
namely
through
a
Material
Safety
Data
Sheet
(
MSDS)?
If
so,
identify
all
such
schemes.
Was
the
linkage
claimed
as
confidential
in
any
of
these
instances?

2.
What
harmful
effect,
if
any,
to
your
competitive
position
do
you
think
would
result
from
disclosure
of
the
identity
of
the
site
and
the
chemical
substance?
How
could
a
competitor
use
such
information?
Would
the
effects
of
disclosure
be
substantial?
What
is
the
causal
relationship
between
the
disclosure
and
the
harmful
effects?

If
you
assert
that
any
of
the
information
contained
in
the
answers
to
these
questions
contains
CBI,
you
must
clearly
identify
the
information
that
is
claimed
confidential
by
marking

submitted
to
EPA
under
this

EPA
may
make
the

for
CBI
packaging
instructions.

5.3
Chemical
Production
Volume
Information
Under
the
IUR,
you
may
check
the
appropriate
box
on
Form
U
to
assert
a
claim
of
confidentiality
for
chemical
production
volume
information,
if
the
information
qualifies
as
confidential
under
Section
14
of
TSCA
and
the
substantive
criteria
under
40
CFR
Part
2.
Additionally,
if
you
do
assert
a
claim
of
confidentiality
for
your
specific
production
volume,
you
may
also
choose
to
determine
if
CBI
protection
is
warranted
for
production
volume
information
in
ranges.
The
ranges
are
similar
to
those
used
for
the
original
TSCA
Inventory
and
are
listed
in
Table
5­
3.
If
you
determine
that
your
production
volume
range
also
warrants
CBI
protection,
you
must
check
the
appropriate
box
on
Form
U
for
claiming
this
information
as
CBI
(

6.2
Correcting
Errors
in
Submissions
for
Original
Inventory
In
reporting
under
the
IUR,
you
may
find
that
an
error
was
made
when
you
reported
for
the
original
Inventory.
That
error
may
fall
into
one
of
the
following
categories:


The
chemical
identity
originally
reported
was
incomplete
or
inaccurate;


An
isolated
intermediate
produced
during
the
manufacture
of
a
substance
was
not
recognized
when
previously
reported
for
the
Inventory;
or

EPA
informed
your
company
of
a
reporting
error
and
requested
a
correction
from
you,
to
which
you
did
not
respond.

If
an
error
occurred,
you
should
file
an
Inventory
Correction,
following
the
procedures
outlined
in
the
Federal
Register
notice
of
July
29,
1980
(
45
FR
50544).
Reference
the
original
Inventory
report
form
and
line
number
(
if
appropriate)
when
you
file
a
correction.
For
copies
of
the
Federal
Register
notice
or

with
an
Inventory
Correction,

Explain
the

in
a

6.3
Recordkeeping
Requirements
The
Inventory
regulations
require
you
to
retain
records
on
IUR
reports
for
5
years
after
the
effective
date
of
the
applicable
reporting
period
(
40
CFR
710.57).
For
example,
if
you
submit
an
IUR
report
in
reporting
year
2006,
you
would
be
required
to
retain
the
records
on
which
the
report
is
based
until
December
23,
2011.

As
long
as
the
records
are
maintained
in
a
manner
consistent
with
normal
business
practice,
you
may
determine
their
exact
format.
Required
records
include
those
that
show
the
production
volume,
plant
site,
and
site­
limited
status
of
each
substance
reported.
If
a
substance
is
not
reported
because
its
site­
specific
annual
production
is
less
than
25,000
pounds,
EPA
suggests
you
maintain
records
to
document
your
reasons
for
not
filing
Form
U.

If
you
qualify
as
an
exempt
small
manufacturer,
you
need
to
keep
records
only
for
those
chemical
substances
that
you
are
required
to
report;
however,
in
claiming
an
exemption,
you
bear
the
burden
of
documenting
that
you
qualify
for
the
exemption.

6.4
Special
Instructions
for
Importers
and
Foreign
Suppliers
This
section
applies
to
importers
who
do
not
know
the
specific
chemical
identity
of
a
substance
because
the
foreign
supplier
chooses
to
keep
it
confidential.
If
you
are
such
an
importer,
you
are
still
responsible
for
ensuring
that
the
information
is
submitted
to
EPA
(
40
CFR
720.25).
You
can
accomplish
this
by
having
your
foreign
supplier
complete
some
of
the
information
on
Form
U,
as
follows:

1.
Include
a
cover
letter
with
your
Form
U,
stating,
"
The
identifying
numbers
and
specific
chemical
identities
for
the
substances
on
this
form
and
the
technical
contact
will
be
submitted
by
our
foreign
supplier."

2.
Use
a
separate
Form
U
for
each
foreign
supplier
who
does
not
inform
you
of
the
identity
of
the
chemical
substances
you
are
importing.
Do
not
report
by
diskette.
Do
not
use
the
same
report
form
for
substances
for
which
you
know
the
specific
identity.

3.
Photocopy
a
blank
Form
U
before
entering
any
information
on
the
form.

4.
On
the
original
form,
sign
the
certification
statement,
enter
the
technical
contact,
and
complete
Parts
I
through
IV
for
each
chemical
substance.
In
Part
II,
Section
I,
Block
1.1,
instead
of
entering
the
identifying
number,
enter
the
trade
name
or
other
designation
by
which
you
know
each
chemical
substance.
Leave
Block
1.2
blank.
Check
the
"
Chemical
CBI"
box
only
if
you
wish
to
claim
the
identities
of
the
chemicals
identified
on
the
form
as
confidential
(
you
must
answer
the
substantiation
questions
described
in
Section
5.1).
Foreign
suppliers
are
responsible
for
their
own
CBI
claims.
Send
this
original
form
to
EPA.

5.
On
the
photocopy
of
the
blank
form,
enter
only
the
plant
site
information.
Send
this
copy
to
your
foreign
supplier
to
complete
and
forward
to
EPA.

6.
The
foreign
supplier
should
enter
technical
contact­
company
information
on
the
copy
(
the
technical
contact
listed
here
should
be
the
foreign
supplier),
complete
Parts
I
through
IV,
and
enter
the
appropriate
specific
chemical
identities
in
Part
II,
Section
I.
Make
sure
that
your
supplier
understands
which
chemical
identities
belong
with
each
copy
of
the
Form
U.
If
the
foreign
supplier
wishes
to
claim
the
DRAFT:
Chapter
6.0
How
to
Submit

Report
to
EPA
6­
4
chemical
identities
as
confidential,
the
supplier
should
check
the
"
CBI"
box
and
submit
a
substantiation
as
described
in
Section
5.1.
The
supplier
should
include
with
Form
U
a
letter
stating
that
this
information
is
being
submitted
by
a
foreign
supplier
on
behalf
of
the
importer,
who
should
be
identified.
Information
in
the
letter
may
be
claimed
as
confidential
by
circling
or
bracketing
the
text
to
be
protected
and
marking
the
page
"
CONFIDENTIAL."
Failure
to
so
mark
this
information
may
result
in
EPA
making
the
information
available
to
the
public
without
further
notice
to
the
supplier.
The
foreign
supplier
should
then
send
the
form
and
letter
to
EPA.

Note
that
it
is
your
responsibility
to
ensure
that
your
foreign
supplier
understands
how
to
complete
the
copy
of
Form
U
(
including
any
relevant
CBI
claims)
and
that
the
supplier
sends
the
information
to
EPA
by
the
end
of
the
reporting
period.
If
the
supplier
fails
to
submit
the
information,
your
company
may
be
subject
to
an
enforcement
action.

in

The

These
can
be
obtained
from
the
National
Technical

(
703­

The
computer

version
consists
of
two

The
first
tape,
the
Inventory

is
sorted
by
CAS

same

as
the
first
tape
but
differs
in
two
ways.
First,
it
is
sorted
by
chemical
name,
not
CAS
Registry
Number.
Second,
in
addition
to
the
CA
Index/
Preferred
names,
this
file
also
includes
valid
names
(
synonyms)
as
supplied
to
EPA
by
Inventory
submitters.
In
contrast
to
the
printed
version
of
the
Public

which
includes
CAS­
derived
synonyms,
the
synonyms
listed
on
this
tape
are
only
those
reported
to
EPA
by
Inventory
submitters.

The
CD

contains
the
information
on
both
computer
tapes
combined,
with
duplicate
information
removed.
CAS
Registry
Numbers
are
listed
