CASE
STUDY
D
This
example
illustrates
how
to
report:
1.
a
hydrate
of
a
chemical
substance;
2.
inorganic
chemical
substances
(
partial
exemption
for
2006
reporting
year);
3.
TSCA­
exempt
use
(
as
a
pesticide).

Scenario:
Company
D
produces
800,000
lbs/
yr
of
copper
sulfate
pentahydrate
(
CuSO

·
5H

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.

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

The
manufacture
and
use
of
pesticides
is
exempt
from
TSCA­
regulations,
therefore
the
portion
of
the
production
volume
used
in
pesticides
does
not
need
to
be
reported
for
Part
III.
Additionally,
copper
sulfate
is
an
inorganic
substance.
For
the
2006
reporting
year,
inorganic
substances
are
partially
exempt,
so
only
Parts
I
and
II
need
to
be
reported.
Company
D
produces
800,000

of
copper
sulfate
pentahydrate

(

at
93%

560,000
lbs.
of
copper

(

240,000

of
copper

is
used
as

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.
The
remaining
16,000,000
pounds
of
xylene
is
shipped
to
15
different
distributors
for
formulation
of
products.
The
distributors
formulate
4,000,000
pounds
of
xylene
and
sell
it
as
a
metal
degreaser
at
95%
concentration
to
200
hardware
manufacturers.
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.).

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
U.
The
200,000
lbs.
of
xylene
used
as
a
component
of
solvents
sold
to
consumers
should
not
be
reported
in
Part
III
because
it
is
less
than
5%
of
the
total
production
volume
and
less
than
the
300,000
pounds
threshold.
The
percent
production
volumes
for
use
as
wood
preservatives
and
paint
used
by
consumers
should
be
reported
to
the
nearest
percentage
point
because
it
is
less
than
5%
of
the
production
volume
and
totals
300,000

or
