INTRODUCTION
This
Appendix
presents
seven
hypothetical
case
studies
to
illustrate
how
to
report
information
on
Form
U.
EPA
designed
the
case
studies
to
cover
a
variety
of
reporting
scenarios.
These
case
studies
are
not
based
on
actual
data,
but
are
hypothetical
situations
generated
to
assist
submitters.
None
of
these
hypothetical
situations
are
binding.
EPA
will
assess
each
situation
in
a
case­
by­
case
basis.
Each
case
study
is
divided
into
the
following
sections:

°
Scenario
­
This
section
presents
a
sample
manufacturing
scenario
for
a
single
chemical
including
processing
and
use
information.
For
some
cases,
a
figure
is
included
to
clarify
the
manufacture,
process,
and
use
information;

°
EPA
Approach
­
This
section
discusses
the
rationale
for
each
of
the
three
criteria
presented
in
Chapter
2
and
identifies
which
parts
of
Form
U
must
be
completed;

°
Key
Points
­
This
section
highlights
important
information
which
is
helpful
for
completing
Form
U;

°
Completing
the
Form
­
This
section
discusses
the
responses
which
should
be
entered
on
Form
U
for
each
manufacturing
scenario.
This
section
explains
the
basis
and
rationale
for
the
reported
information;
and
°
Sample
Form
U
­
A
completed
Form
U
for
each
scenario
is
included.
Part
I
of
Form
U
was
completed
for
Case
Study
A
only.
Parts
II
and
III
of
Form
U
were
completed
for
all
cases,
as
necessary.

EPA
created
these
case
studies
to
cover
the
following
frequently
asked
questions:

1.
How
do
I
know
if
my
chemical
is
site
limited?
A
chemical
is
site
limited
if
it
is
manufactured
at
your
plant
site
and
you
do
not
distribute
the
substance
or
any
mixture
containing
the
substance
outside
the
plant
site
for
commercial
purposes.
See
Section
4.6.3
and
Case
Study
A
for
additional
guidance.

What
if
my
site
only
imports
a
chemical?
Manufacturers
and
importers
are
required
to
report
under
the
IURA.
Importers
should
check
the
"
import"
box
in
Block
2.
B.

Sections
2.2.1.2
and
4.6.4
and
Case
Study
B
of
this
document
provide
additional
guidance
for
reporting
this
information.

3.
What
if
my
site
exports
the
entire
volume
of
the
manufactured
chemical?
If
you
manufacture
an
IUR­
reportable
chemical
substance
solely
for
export,
you
are
required
to
report
and
otherwise
comply
with
all
IUR
requirements
for
Parts
I
and
II
of
Form
U.
Case
Study
C
illustrates
how
to
complete
Form
U
for
a
chemical
that
is
exported.

4.
What
if
my
site
both
manufactures
and
imports
the
same
chemical?
Sites
both
manufacturing
and
importing
a
chemical
substance
should
check
both
boxes
in
Block
2.
B.
4.
The
total
volume
of
chemical
(
both
manufactured
and
imported)
should
be
reported
in
Parts
II
and
III
of
Form
U.
See
Sections
2.2.1.2
and
4.6.4
and
Case
Study
G
for
additional
guidance.

5.
How
do
I
report
the
number
of
workers
at
my
site
and
at
downstream
sites?
Estimates
for
the
number
of
workers
reasonably
likely
to
be
exposed
are
required
for
both
the
manufacturing
and
industrial
processing
sections
of
Form
U.
Sections
4.6.7
and
4.7.1.6
of
this
document
describe
how
to
report
these
codes
and
give
examples
of
worker
activities
that
could
potentially
result
in
exposure.
All
case
studies
provide
examples
of
how
to
report
the
number
of
potentially
exposed
workers
along
with
the
basis
and
rationale
for
selecting
the
reported
code.

6.
How
do
I
report
the
maximum
concentration
of
my
chemical?
You
are
required
to
report
the
maximum
concentration,
by
weight,
of
your
chemical
at
the
time
it
sent
off­
site
from
each
site.
If
a
chemical
is
site­
limited,
report
the
maximum
concentration
before
it
is
reacted
on­
site
to
produce
a
different
chemical
substance.
Section
4.6.8
of
this
document
provides
guidance
for
reporting
this
information.

7.
What
if
I
manufacture
my
chemical
in
more
than
one
physical
form?
You
are
required
to
report
all
physical
forms
of
the
chemical
substance
at
the
time
it
leaves
your
site
and
the
percent
of
production
volume
for
each
form.
The
percentage
must
be
rounded
off
to
the
nearest
10%;
the
sum
of
the
percentages
for
each
form
must
not
add
up
to
more
than
100%.
Section
4.6.9
of
this
document
provides
guidance
for
reporting
the
physical
form
and
the
percent
production
volume
in
each
physical
form.

What
if
there
are
multiple
NAICS,
IFC,
and
"
Types
of
Process
or
Use"
code
combinations
for
my
chemical?
You
are
required
to
report
up
to
ten
unique
combinations
of
codes.
If
more
than
10
unique
combinations
apply,
you
need
only
report
the
ten
combinations
that
represent
the
largest
percentage
of
production
volume.
Section
4.7.1
and
Case
Studies
F
and
G
provide
additional
guidance.

9.
What
if
my
percent
production
volume
is
less
than
5%
for
a
process/
use,
NAICS,
and
IFC
code
combination
and
the
total
production
volume
is
less
than
300,000
pounds?
As
discussed
in
Section
4.7.1.4
of
this
document,
if
a
particular
combination
accounts
for
less
than
5%
of
the
percent
production
volume
and
is
less
than
300,000
pounds,
then
you
may
report
the
percent
production
volume
as
0%.
Case
Study
G
illustrates
how
to
report
this
information.

10.
What
if
my
percent
production
volume
is
less
than
5%
for
a
process/
use,
NAICS,
and
IFC
code
combination
but
the
total
production
volume
is
greater
than
300,000
pounds?
As
discussed
in
Section
4.7.1.4
of
this
document,
if
a
particular
combination
accounts
for
less
than
5%
of
the
percent
production
volume
and
is
300,000
pounds
or
greater,
then
you
must
report
the
percent
production
volume
to
the
nearest
1%
of
production
volume.
Case
Study
G
illustrates
how
to
report
this
information.

11.
What
if
the
values
I
report
for
percent
production
volume
for
each
end
use
add
up
to
more
than
100%?
As
discussed
in
Section
4.7.1.4,
the
total
percent
production
volumes
may
add
up
to
more
than
100%
since
you
are
reporting
on
the
distribution
of
the
chemical
to
downstream
sites.
The
values
may
add
up
to
less
than
100%
if
the
information
on
production
volume
is
not
readily
obtainable.
Case
Studies
F
and
G
illustrate
how
to
report
this
information.

12.
What
if
my
chemical
has
multiple
commercial
and
consumer
uses?
You
must
report
up
to
10
commercial
and
consumer
product
categories
for
which
your
chemical
is
used.
Section
4.7.2.1
and
Case
Studies
F
and
G
provide
additional
guidance
for
completing
Column
"
a"
in
Part
III,
Section

13.
What
if
my
substance
is
used
in
children's
products?
You
must
determine,
within
each
commercial
and
consumer
product
category
reported,
whether
any
amount
of
each
reportable
chemical
substance
is
present
in
consumer
products
intended
for
use
by
children
age
14
or
younger.

How
do
I
report
chemicals
that
are
intermediates?
Definitions
for
"
intermediate"
and
"
non­
isolated
intermediate"
are
provided
in
Appendix
B.
Section
2.2.3
of
this
document
states
that
impurities,
byproducts,
and
non­
isolated
intermediates
are
exempt
from
reporting.
However,
reporting
the
manufacture
of
an
isolated
intermediate
is
required.
Case
Study
A
provides
a
possible
scenario
for
reporting
an
isolated
intermediate.
Additional
examples
are
available
in
section
2.2.3
of

How
do
I
report
hydrates
of
a
chemical
substance?
You
are
required
to
complete
Form
U
for
the
corresponding
anhydrous
form.
Section
2.1.1.2
of
this
document
specifically
addresses
how
to
report
a
hydrate
of
a
chemical
substance
and
provides
an

presents
another
example
of
how
to
report
a
hydrate
of
a
chemical
substance.

16.
How
do
I
report
inorganic
chemical
substances?
Inorganic
chemical
substances
are
partially
exempt
from
reporting
for
the
2006
reporting
period
and
will
not
be
exempt
for
subsequent
reporting
periods.
For
the
2006
reporting
period,
you
only
need
to
complete
Parts
I
and

2006
reporting
period.

17.
What
if
my
chemical
is
listed
on
the
"
specific
exempted
chemical

CASE
STUDY
A
This
example
illustrates
how
to
report:

Site­
limited
chemicals;
and

Intermediates.

Scenario:
Company
A
manufactures
1,100,000
lbs/
yr
of
an
intermediate
called
Monomer
#
1
(
Accession
#
99999)
at
the
Big
Lot
site.
Monomer
#
1
is
used
for
the
manufacture
of
a
polyamide
and
is
sitelimited
meaning
it
is
only
used
at
the
Big
Lot
site.
Monomer
#
1
is
produced
as
part
of
a
liquid
solution
at
89.6%
concentration
and
transferred
to
an
on­
site
storage
tank
for
future
use.
Monomer
#
1
is
subsequently
consumed
during
the
reaction
to
produce
the
polyamide.
Twelve
workers
are
potentially
exposed
during
the
manufacture
of
Monomer#
1
during
sampling
and
equipment
cleaning.
Two
additional
workers
transfer
Monomer
#
1
from
the
storage
tank
to
the
reactor
that
produces
the
polyamide.
Four
administrative
workers
are
on­
site
but
not
directly
involved
with
the
manufacture
of
any
chemicals.

John
Doe
is
the
plant
manager
for
the
Company
A's
Big
Lot
site.
The
mailing
address
for
this
site
is
100
John
Doe
Highway,
Richmond,
VA
23222.
The
Dun
&
Bradstreet
number
for
the
site
is
099999999.
The
mailing
address
for
Company
A's
headquarters
is
100
First
Street,
Suite
100,
New
York,
NY
10001.
The
Dun
&
Bradstreet
number
for
this
office
is
999999999.

EPA
Approach:
Criterion
I:
Monomer
#
1
is
on
the
TSCA
Inventory
and
in
not
subject
to
a
special
regulatory
action
under
TSCA.
Monomer
#
1
is
used
to
produce
a
polyamide.
The
polyamide
is
excluded
from
reporting
under
the
polymer
exemption,
but
Monomer
#
1
does
not
qualify
for
this
exemption.

Criterion
II:
Company
A
manufactures
25,000
pounds
or
more
of
Monomer
#
1
and
does
not
qualify
as
a
small
manufacturer.
Monomer
#
1
is
considered
to
be
site­
limited
because
it
is
not
imported
to
the
site
and
does
not
leave
the
site.
Monomer
#
1
is
defined
as
isolated
because
the
transfer
operation
from
the
reactor
to
the
storage
tank
isolates
Monomer
#
1;
therefore,
Monomer
#
1
does
not
qualify
for
the
nonisolated
intermediate
exemption.

Criterion
III:
Company
A
manufactures
300,000
pounds
for
more
of
Monomer
#
1
and
Monomer
#
1
does
not
qualify
for
any
partial
exemptions.
Therefore,
Company
A
must
complete
Parts
I,
II,
and
III.

CASE
STUDY
B
This
example
illustrates
how
to
report:

A
chemical
substance
that
is
imported
only;

TSCA­
exempt
uses
(
cosmetic
lotions).

Scenario:
Company
B
imports
400,000
pounds
of
2­
propanol
(
IPA)
(
CAS#
67­
63­
0)
to
its
only
site
during
a
reporting
year
as
part
of
a
liquid
solution
at
95%
concentration.
Company
B
employs
5
workers
per
shift
for
3
shifts
(
15
total
workers)
to
incorporate
the
IPA
into
mixtures
and
formulations
ranging
from
10%
to
50%
in
concentration.
Half
the
production
volume
(
200,000
pounds)
is
incorporated
into
industrial
solvents
and
cleaners
and
is
sold
to
hundreds
of
sites.
Company
B
estimates
3
workers
are
exposed
at
each
of
these
sites.
100,000
pounds
of
IPA
is
used
in
commercially­
used
soaps
and
cleaners.
The
remaining
100,000
pounds
is
incorporated
into
cosmetic
lotions
for
consumer
use.
The
soap
and
lotion
products
are
used
at
thousands
of
sites.

EPA
Approach:
Criterion
I:
IPA
is
on
the
TSCA
Inventory
and
is
not
a
substance
excluded
from
reporting.

Criterion
II:
Company
B
imported
25,000
pounds
or
more
of
IPA
and
does
not
qualify
as
a
small
manufacturer.
Company
B
does
not
qualify
for
any
additional
reporting
exemptions
for
IPA.

Criterion
III:
Company
B
imported
300,000
pounds
or
more
of
IPA
and
the
IPA
is
not
listed
as
a
partial
exemption;
therefore,
Company
B
must
report
Parts
I,
II,
and
III
for
IPA.

Key
Points:
Since
IPA
is
imported,
no
exposed
workers
are
reported
for
the
manufacturing
section
in
Part
II.
Use
of
cosmetic
lotions
is
exempt
from
TSCA
reporting
because
it
is
regulated
by
the
Food
and
Drug
Administration
(
FDA),
but
the
manufacture
and
processing
of
IPA
into
these
products
is
not
exempt.
Therefore,
the
consumer
use
of
cosmetic
lotions
is
not
required
in
Part
III
of
Form
U
and
does
not
need
to
be
reported.

This
example
illustrates
how
to
report:

$
A
chemical
substance
that
is
exported
only
(
production
volume
is
300,000
lbs/
yr
or
more).

Scenario:
Company
C
manufactures
400,000
pounds
of
liquid
cyclohexane
(
CAS#
110­
82­
7)
in
solution
at
90%
concentration
during
a
reporting
year.
The
manufacturer
exports
the
entire
production
volume
outside
the
United
States.
Since
cyclohexane
is
extremely
volatile,
all
manufacturing
operations
occur
in
closed
systems
with
engineering
controls
to
minimize
releases
and
worker
exposures.
However,
Company
C
estimates
4
workers
will
perform
transfer
and
drumming
operations
and
4
workers
will
perform
maintenance
and
equipment
cleaning
activities.

EPA
Approach:
Criterion
I:
Cyclohexane
is
on
the
TSCA
Inventory
and
is
not
excluded
from
reporting.

Criterion
II:
Company
C
manufactures
25,000
pounds
or
more
of
cyclohexane
and
does
not
qualify
as
a
small
manufacturer.
Company
C
does
not
qualify
for
any
additional
reporting
exemptions.

Criterion
III:
Company
C
manufactures
300,000
pounds
or
more
of
cyclohexane
and
cyclohexane
does
not
qualify
for
any
partial
exemptions.
Therefore,
Company
C
must
complete
Parts
I,
II,
and
III
of
Form
U
for
cyclohexane.

Key
Points:

Company
C
should
report
8
workers
potentially
exposed
during
manufacturing
operations
despite
the
use
of
engineering
controls
and
personal
protection
equipment.

Reporting
the
industrial,
commercial,
and
processing
use
information
of
this
chemical
is
not

This
example
illustrates
how
to
report:

A
hydrate
of
a
chemical
substance;

Inorganic
chemical
substances
(
partial
exemption
for
2006
reporting
year);
and

TSCA­
exempt
use
(
as
a
pesticide).

Scenario:
Company
D
produces
800,000
lbs/
yr
of
copper
sulfate
pentahydrate
(
CuSO
4
·
5H
2
O)
crystals
at
93%
purity.
70%
of
the
production
volume
is
used
for
metal
electroplating
and
30%
is
used
as
pesticides.
This
site
employs
60
workers
in
the
manufacturing
area.

EPA
Approach:
Criterion
I:
Copper
sulfate
pentahydrate
is
a
hydrate
and
not
listed
on
the
TSCA
Inventory.
However,
copper
sulfate
is
on
the
TSCA
Inventory
and
is
required
to
be
reported
under
IUR.
Copper
sulfate
does
not
qualify
as
a
substance
excluded
from
reporting.

Criterion
II:
Company
D
manufacturers
25,000
pounds
or
more
of
copper
sulfate
(
not
copper
sulfate
pentahydrate)
and
does
not
qualify
as
a
small
manufacturer.
Company
D
does
not
qualify
for
any
additional
reporting
exemptions.

Criterion
III:
Company
D
manufactures
300,000
pounds
or
more
of
copper
sulfate
(
not
copper
sulfate
pentahydrate).
Copper
sulfate
is
an
inorganic
substance
and
is
partially
exempted
for
the
2006
reporting
period.
Therefore,
Company
D
must
complete
Parts
I
and
II
of
Form
U
for
copper
sulfate.

Key
Points:

This
material
is
a
hydrate,
therefore
only
the
weight
fraction
of
the
non­
hydrated
form
of
copper
sulfate
(
CuSO
4)
(
CAS#
7758­
98­
7)
should
be
reported.
To
determine
the
weight
fraction,
multiply
the
production
volume
of
the
copper
sulfate
pentahydrate
by
the
molecular
weight
of
copper
sulfate
(
CuSO
4)
divided
by
the
molecular
weight
of
the
copper
sulfate
pentrahydrate
(
CuSO

when
the
sum
of
the

is
greater
than
100%.

Scenario:
At
one
site,
Company
F
manufacturers
a
total
of
800,000
lb/
yr
of
C.
I.
Pigment
Yellow
100
(
CAS#

of
C.
I.
Pigment
Yellow

is
sold
as
a
liquid
at
concentrations
between
1%
and
30%
as
a
coloring
agent
to
approximately
50
paint
manufacturers.
The
paint
manufacturers
then
sell
60%
of
this
paint
(
300,000
lbs.)
directly
to
the
consumer
and
the
other
40%
to
about
10
toy
manufacturers
that
paint
wooden

Scenario:
Company
G
produced
19,000,000
pounds
of
xylene,
mixed
isomers
(
CAS#
1330­
20­
7)
(
referred
to
as
xylene
throughout
this
case
study)
and
imported
an
additional
1,000,000
pounds
during
the
same
reporting
year
to
the
same
site.
The
xylene
is
manufactured
at
100%
concentration.
Company
G
estimates
8
exposed
workers
during
the
manufacture
of
xylene
for
sampling
and
maintenance,
in
addition
to
6
exposed
workers
during
the
drumming
of
product.

Company
G
distributes
4,000,000
pounds
of
xylene
directly
to
3
chemical
manufacturing
facilities
at
100%
concentration
to
be
used
as
a
chemical
reactant.
Company
G
estimates
4
workers
are
potentially
exposed
at
each
manufacturing
facility
to
transfer
the
xylene
from
shipping
containers
to
the
reactor.

The
remaining
16,000,000
pounds
of
xylene
is
shipped
to
15
different
distributors
for
formulation
of
products.
Company
G
estimates
6
workers
are
potentially
exposed
at
each
distribution
site.
The
distributors
formulate
4,000,000
pounds
of
xylene
and
sell
it
as
a
metal
degreaser
at
95%
concentration
to
200
hardware
manufacturers;
and
Company
G
estimates
3
workers
are
potentially
exposed
to
xylene
per
hardware
manufacturer.
The
formulator
dilutes
the
remaining
12,000,000
pounds
such
that
xylene
is
present
at
a
concentration
ranging
between
0.5%
and
95%
and
places
the
final
product
into
smaller
containers.
Of
the
12,000,000
pounds
of
xylene
that
is
processed,
6,000,000
pounds
is
used
in
automotive
care
products
(
35%
max.
conc.)
used
both
commercially
and
by
consumers.
3,200,000
pounds
will
be
used
in
paint
formulations
(
15%
max.
conc.)
which
are
then
sold
for
commercial
and
consumer
applications.
2,200,000
pounds
is
formulated
into
pesticides
(
10%
max
conc.)
which
is
then
sold
for
commercial
use.
400,000
pounds
is
sold
for
formulation
of
a
wood
preservative
(
20%
conc.)
to
be
used
on
furniture
for
residential
use.
200,000
pounds
is
sold
as
a
component
of
solvents
on
the
consumer
market
(
95%
max
conc.).

EPA
Approach:
Pesticides
are
regulated
by
the
Federal
Insecticide,
Fungicide,
and
Rodenticide
Act
(
FIFRA)
and
are
exempt
from
TSCA
regulations.
Therefore,
the
portion
of
xylene
used
in
pesticides
does
not
need
to
be
reported
under
IUR.

Criterion
I:
Xylene
is
listed
on
the
TSCA
Inventory
and
is
not
a
substance
excluded
from
DRAFT:
Appendix
G
Case
Studies
G­
34
reporting.

Criterion
II:
Company
G
manufactures
25,000
pounds
or
more
of
xylene
and
does
not
qualify
as
a
small
manufacturer.
Company
G
does
not
qualify
for
any
additional
reporting
exemptions.

Criterion
III:
Company
G
manufactures
300,000
pounds
or
more
of
xylene
and
does
not
qualify
for
any
partial
exemptions.
Therefore,
Company
G
must
complete
Parts
I,
II,
and
III
of
Form
U
for
xylene.

Key
Points:

Pesticides
are
exempt
from
regulation
under
TSCA,
therefore
the
use
of
xylene
for
the
preparation
of
a
commercial
pesticide
formulation
does
not
need
to
be
included
in
Form

The

lbs.
of
xylene
used
as
a
component
of
solvents
sold
to
consumers
should
not
be
reported
in

because
it
