section
4(
a)
of
TSCA
requiring
testing
of
chemicals
and
chemical
mixtures
in
order
to
develop
data
relevant
to
determining
the
risks
that
such
chemicals
and
chemical
mixtures
may
present
to
health
or
the
environment.
Section
4(
e)
of
TSCA
established
the
ITC
to
recommend
chemicals
and
chemical
mixtures
to
the
Administrator
of
the
EPA
for

ITC's
Activities
During
this
Reporting
Period
(
May
to
November
2002)

A.
Voluntary
Information
Submissions
To
promote
more
efficient
use
of
information
submission
resources,
the
ITC
developed
the
VISP
and
the
VISION.
The
VISP
is
described
in
the
ITC's
41st
Report
(
Ref.
9),
while
the
VISION
is
described
in
the
ITC's
42nd
Report
(
Ref.
5).
The
ITC
developed
the
VISP
and
VISION
as
tools
to
provide
a
more
cost­
effective
method
for
chemical
producers,
importers,
processors,
and
users
of
ITC­
recommended
chemicals
to
provide
voluntary
information.
Except
for
a
few
industries,
the
ITC
received
voluntary
information
submissions
through
the
VISION
on
<
15%
of
the
chemicals
for
which
voluntary
information
was
solicited.
The
ITC
has
not
yet
determined
the
reasons
for
the
apparent
low
utilization
of
the
VISION.
In
its
50th
Report
(
Ref.
4),
the
ITC
requested
comments
on
procedures
that
could
be
implemented
to
make
the
VISION
or
other
procedures
for
submitting
voluntary
information
more
effective.
The
American
Chemistry
Council
(
ACC)
provided
an
explanation
of
the
chemical
industry's
limited
participation
in
the
VISION
(
Ref.
10).
The
ACC
expressed
concerns
about
the
need
to
protect
Confidential
Business
Information
(
CBI),
the
problems
associated
with
soliciting
voluntary
submissions
on
non­
HPV
chemicals,
the
potential
non­
existence
of
specific
data
being
requested
by
the
ITC,
and
the
resources
required
to
submit
studies
in
portable
document
format
(
PDF).
To
supplement
the
efforts
to
obtain
studies
in
PDF
through
the
VISION,
the
ITC
Staff
has
been
contacting
the
producers
and
importers
of
ITCrecommended
chemicals
to
obtain
voluntary
information
submissions.
These
efforts
were
highly
successful
for
the
chemicals
identified
through
DEBITS.
The
ITC
Staff
will
continue
to
contact
the
producers
and
importers
of
ITC­
recommended
chemicals
to
obtain
voluntary
information
submissions
as
it
continues
its
efforts
to
improve
the
utility
of
the
VISP
and
VISION.
During
this
reporting
period,
the
ITC
acknowledges
the
voluntary
information
submissions
from
the
following
organizations:
3M
Corporation;
Albemarle
Corporation;
Amfine
Chemical
Corporation;
Alkylphenol
&
Ethoxylates

Following
the
transmittal
of
this
51st
Report
to
the
USEPA
Administrator,
the
ITC
Staff
will
contact
the
producers
and
importers
of
the
9
indium
compounds
remaining
on
the
Priority
Testing
List
to
obtain
the
following
information
to
adequately
access
the
extent
and
degree
of
exposure
and
potential
hazard
associated
with
indium
compounds:
1.
Recent
non­
CBI
estimates
of
annual
production
or
importation
volume
trends.
2.
Use
information,
including
percentages
of
production
or
importation
that
are
associated
with
different
uses.
3.
Estimates
of
the
number
of
workers
and
concentrations
of
indium
compounds
to
which
workers
may
be
exposed
during
manufacture
or
processing
including
smelting
processes,
leaching
processes,
recovery
of
scrap
material,
deposition
of
film
coatings,
soldering,
and
production
of
electrical
components
including,
but
not
limited
to
semiconductors.
B.
DEBITS
In
its
45th
through
50th
Reports
(
Refs.
2
 
4,
6,
7,
and
11),
the
ITC
described
its
strategies
to
screen
and
evaluate
chemicals
with
persistence
and
bioconcentration
potential.
These
activities
are
referred
to
as
DEBITS.
DEBITS
provides
a
means
to
prioritize
chemicals
for
information
reporting
and
testing
based
on
degradation
and
bioconcentration
potential
and
availability
of
effects
data.
For
DEBITS
1,
the
ITC
used
criteria
to
screen
12,685
chemicals
and
ultimately
review
458,
the
disposition
of
which
was
described
in
the
45th
through
50th
Reports
(
Refs.
2
 
4,
6,
7,
and
11).
As
a
result
of
implementing
DEBITS
1,
the
Priority
Testing
List
contains
three
chemicals
with
persistence
and
bioconcentration
potential
that
the
USEPA
may
consider
for
its
PBT
Program:
Benzenamine,
3­
chloro­
2,6­
dinitro­
N,
N­
dipropyl­
4­
(
trifluoromethyl)­;
stannane,
dimethylbis[(
1­
oxoneodecyl)
oxy]­;
and
benzene,
1,3,5­
tribromo­
2­(
2­
propenyloxy)­.
DEBITS
2
started
with
8,511
chemicals
with
production
volumes
>
10,000
lbs
reported
to
USEPA
in
response
to
the
1998
Inventory
Update
Rule
(
IUR).
From
these
8,511
chemicals,
30
non­
HPV
chemicals
were
identified
that
had
1998
production
volumes
>
50,000
lbs,
predicted
biodegradation
half­
lives
>
2
months
and
predicted
bioconcentration
factors
>
1,000.
The
ITC
contacted
manufacturers
and
importers
of
these
30
DEBITS
2
chemicals
to
solicit
voluntary
information
on
production
and
uses,
and
unpublished
toxicity
data.
The
ITC
received
production
and
use
information
for
22
DEBITS
2
chemicals
and
unpublished
toxicity
studies
for
13
DEBITS
2
chemicals.
After
reviewing
this
and
other
available
information
the
ITC
deferred
the
30
DEBITS
2
chemicals
for
information
reporting
rules.
A
brief
rationale
for
deferring
each
DEBITS
2
chemical
is
given
in
Table
3
of
this
unit.

Recommendation.
Forty­
three
vanadium
compounds
are
being
added
to
the
Priority
Testing
List
to
obtain
importation,
production,
use,
exposure,
and
health
effects
information
to
meet
U.
S.
Government
data
needs
(
Table
4
of
this
unit).
These
compounds
were
identified
by
searching
reference
sources
and
chemical
databases
maintained
by
agencies
in
the
United
States
and
Canada.
The
ITC
believes
the
list
of
vanadium
compounds
in
Table
4
of
this
unit
includes
those
most
likely
to
be
in
current
use.
Toxicological
effects
of
vanadium
compounds
were
recently
summarized
by
the
International
Program
on
Chemical
Safety
under
the
auspices
of
the
World
Health
Organization
(
WHO)
(

Rationale
for
recommendation.
Long­
term
inhalation
exposure
to
vanadium
pentoxide
increased
the
incidence
of
lung
tumors
in
male
and
female
mice.
As
a
result,
vanadium
pentoxide
and
other
vanadium
compounds
may
be
potentially
carcinogenic
to
humans.
Existing
occupational
exposure
limits
for
vanadium
dusts
were
primarily
developed
to
protect
workers
from
irritation
and
acute
pulmonary
effects
and
may
not
be
sufficiently
protective
against
an
increased
risk
of
lung
cancer.
3.
Information
needs.
The
ITC
needs:
i.
Recent
non­
CBI
estimates
of
annual
production
or
importation
volume
data
and
trends,
and
use
information,
including
percentages
of
production
or
importation
that
are
associated
with
different
uses.
ii.
Estimates
of
the
number
of
humans
and
concentrations
of
vanadium
chemicals
to
which
humans
may
be
exposed
in
each
relevant
manufacturing
or
processing
scenario.
iii.
Health
effects
data
including
pharmacokinetics,
genotoxicity,
subchronic
toxicity,
reproductive
and
developmental
toxicity,
and
any
human
data
from
occupationally
exposed
workers.
The
ITC
seeks
this
information
in
order
to
adequately
assess
the
extent
and
degree
of
exposure
and
potential
hazard
associated
with
the
various
forms
of
vanadium.
4.
Supporting
information.
Vanadium
is
widely
distributed
in
low
amounts
as
a
constituent
of
mineral
ores
and
crude
petroleum
deposits.
The
U.
S.
consumption
of
vanadium
compounds
was
reported
to
be
3,210
metric
tons
in
2001
(
Ref.
14).
The
majority
of
vanadium
was
utilized
as
an
alloying
agent
in
the
steel
industry
or
in
the
production
of
ferrovanadium
and
other
metal
alloys.
A
smaller
portion
of
vanadium
was
used
as
industrial
catalysts
and
in
the
production
of
pesticides,
dyes,
inks,
and
pigments.
More
recent
applications
of
vanadium
compounds
are
thought
to
include
manufacture
of
semiconductors,
vanadate
glasses,
and
electro­
optical
switches.
There
were
over
5,000
potentially
exposed
workers
reported
in
the
National
Occupational
Exposure
Survey
conducted
between
1980
and
1983.
Vanadium
exposure
has
been
found
in
over
300
personal
air
samples
reported
in
OSHA's
Integrated
Management
Information
System
since
1995.
Worker
exposures
are
known
to
occur
during
manufacture
and
handling
of
vanadium
containing
materials,
such
as
welding
operations
or
during
cleaning
of
oil­
fired
furnaces
and
boilers.
General
population
exposure
to
vanadium
most
likely
occurs
through
ingestion
of
food­
bearing
soil
residue
and
inhaled
air
in
areas
with
high
levels
of
residual
fuel
oil
consumption
(
Ref.
15).
For
vanadium
pentoxide
and
most
vanadium
dusts
and
fumes,
NIOSH's
Recommended
Exposure
Limit
(
REL)
is
a
ceiling
value
of
0.05
milligram/
meter
cubed
(
mg/
m3).
The
American
Council
of
Government
Industrial
Hygienists
(
ACGIH)
threshold
limit
value
(
TLV)
for
vanadium
pentoxide
is
0.05
mg/
m3
as
an
8
 
hour
time
weighted
average.
OSHA's
Permissible
Exposure
Limit
(
PEL)
is
a
0.1
mg/
m3
ceiling
for
vanadium
pentoxide
fumes
and
a
0.5
mg/
m3
ceiling
for
respirable
dust.
These
occupational
exposure
limits
were
developed
to
protect
against
respiratory
tract
irritation
and
acute
pulmonary
effects
and
may
not
be
adequate
against
an
increased
risk
of
lung
cancer.
In
a
2­
year
inhalation
study,
NTP
found
clear
evidence
of
carcinogenic
activity
of
vanadium
pentoxide
(

The
incidence
of
benign
and
malignant
neoplasms
was
increased
in
the
lungs
of
the
experimental
animals
at
doses
of
1,
2,
and
4
mg/

There
was
also
some
lesser
evidence
of
increased
lung
tumor
incidence
in
male
and
female
rats
at
similar
exposure
levels.
Exposures
to
vanadium
pentoxide
caused
a
spectrum
of
nonneoplastic
lesions
in
the
respiratory
tracts
of
rats
and
mice,
including
epithelial
hyperplasia,
inflammation
and
fibrosis.
The
NTP
report
raises
concerns
for
other
vanadium
chemicals
and
their
potential
health
effects.

Chemicals
Removed
From
the
Priority
Testing
List
1.
Thiophenol.
Thiophenol
(
CAS
No.
108
 
98
 
5)
was
designated
in
the
ITC's
28thReport
(
Ref.
16)
because
there
was
a
low
confidence
in
the
Reference
Dose
(
RfD)
and
no
Reference
Concentration
(
RfC).
The
USEPA's
RfC/
RfD
Workgroup
requested
that
the
ITC
review
health
effects
data
for
thiophenol
and
recommend
health
effects
testing
that
would
increase
the
confidence
in
the
RfD
and
provide
a
RfC.
Since
thiophenol
was
designated,
the
ITC
has
learned
that
it
is
not
currently
produced
in
the
United
States,
that
the
NTP
has
conducted
developmental
toxicity
(
Refs.
17
and
18)
and
reproductive
effects
(
Ref.
19)
studies,
and
that
Japan
is
developing
a
SIDS
dossier.
Thiophenol
is
being
removed
from
the
Priority
Testing
List
because
it
is
no
longer
produced
and
the
ITC
anticipates
the
SIDS
dossier
will
address
the
testing
data
needs
recommended
by
the
ITC.
