Fifty-Sixth Report of the TSCA
Interagency Testing Committee to the
Administrator of the Environmental
Protection Agency; Receipt of Report
and Request for Comments
Environmental Protection
Agency (EPA).
ACTION: Notice.
AGENCY:
SUMMARY: The Toxic Substances Control
Act (TSCA) Interagency Testing
Committee (ITC) transmitted its 56th ITC
Report to the Administrator of EPA on
September 15, 2005. In the 56th ITC
Report, which is included with this
notice, the ITC is revising the TSCA
section 4(e) Priority Testing List by
adding 5 High Production Volume
(HPV) orphan chemicals and 2 tungsten
compounds and removing 28 HPV
orphan chemicals, 3 pyridinamine
compounds, 6 indium compounds, and
6 vanadium compounds. The ITC is
requesting that EPA add the 5 HPV
orphan chemicals and 2 tungsten
compounds to the TSCA section 8(a)
Preliminary Assessment Information
Reporting (PAIR) rule and the 5 HPV
orphan chemicals to the TSCA section
8(d) Health and Safety Data Reporting
(HaSDR) rule. To facilitate the efforts of
EPA, other Federal and State agencies,
interested stakeholders, and members of
the public in obtaining basic health
effects and environmental data on HPV
chemicals, the ITC conducted a
December 2004 Data-Availability Study
of 235 substances that were HPV
chemicals in the 1998 and 2002
Inventory Update Rules (IURs), but not
in the 1990 or 1994 IURs. The study is
discussed and the list of 235 substances
is appended to this 56th ITC Report.
DATES: Comments must be received on
or before November 23, 2005.
ADDRESSES: Comments, identified by
docket identification (ID) number
OPPT–2005–0039, may be submitted

delivery/courier. To ensure proper
receipt by EPA, identify the appropriate
docket ID number in the subject line on
the first page of your comment. Please
ensure that your comments are
submitted within the specified comment
period. Comments received after the
close of the comment period will be
marked ‘‘late.’’ EPA is not required to
consider these late comments. If you
wish to submit CBI or information that
is otherwise protected by statute, please
follow the instructions in Unit I.D. Do
not use EPA Dockets or e-mail to submit
CBI or information protected by statute.
1. Electronically. If you submit an
electronic comment as prescribed in this
unit, EPA recommends that you include
your name, mailing address, and an email address or other contact
information in the body of your
comment. Also include this contact
information on the outside of any disk
or CD ROM you submit, and in any
cover letter accompanying the disk or
CD ROM. This ensures that you can be
identified as the submitter of the
comment and allows EPA to contact you
in case EPA cannot read your comment
due to technical difficulties or needs
further information on the substance of
your comment. EPA’s policy is that EPA
will not edit your comment, and any
identifying or contact information
provided in the body of a comment will
be included as part of the comment that
is placed in the official public docket,
and made available in EPA’s electronic
public docket. If EPA cannot read your
comment due to technical difficulties
and cannot contact you for clarification,
EPA may not be able to consider your
comment.
i. EPA Dockets. Your use of EPA’s
electronic public docket to submit
comments to EPA electronically is
EPA’s preferred method for receiving
comments. Go directly to EPA Dockets
at https://www.epa.gov/edocket/, and
follow the online instructions for

D. How Should I Submit CBI to the
Agency?
Do not submit information that you
consider to be CBI electronically
through EPA’s electronic public docket
or by e-mail. You may claim
information that you submit to EPA as
CBI by marking any part or all of that
information as CBI (if you submit CBI
on disk or CD ROM, mark the outside
of the disk or CD ROM as CBI and then
identify electronically within the disk or
CD ROM the specific information that is
CBI). Information so marked will not be
disclosed except in accordance with
procedures set forth in 40 CFR part 2.
In addition to one complete version of
the comment that includes any
information claimed as CBI, a copy of
the comment that does not contain the
information claimed as CBI must be
submitted for inclusion in the public
docket and EPA’s electronic public
docket. If you submit the copy that does
not contain CBI on disk or CD ROM,
mark the outside of the disk or CD ROM
clearly that it does not contain CBI.
Information not marked as CBI will be
included in the public docket and EPA’s

II. Background
The Toxic Substances Control Act
(TSCA) (15 U.S.C. 2601 et seq.)
authorizes the Administrator of EPA to
promulgate regulations under TSCA
section 4(a) requiring testing of
chemicals and chemical groups in order
to develop data relevant to determining
the risks that such chemicals and
chemical groups may present to health
or the environment. Section 4(e) of
TSCA established the ITC to
recommend chemicals and chemical
groups to the Administrator of EPA for
priority testing consideration. Section
4(e) of TSCA directs the ITC to revise
the TSCA section 4(e) Priority Testing
List at least every 6 months.

SUMMARY
The ITC is revising the Toxic
Substances Control Act (TSCA) section
4(e) Priority Testing List by adding 5
High Production Volume (HPV) orphan
chemicals and 2 tungsten compounds
and removing 28 HPV orphan
chemicals, 3 pyridinamine compounds,
6 indium compounds, and 6 vanadium
compounds. The ITC is requesting that
EPA add the 5 HPV orphan chemicals
and 2 tungsten compounds to the TSCA
section 8(a) Preliminary Assessment
Information Reporting (PAIR) rule and
the 5 HPV orphan chemicals to the
TSCA section 8(d) Health and Safety
Data Reporting (HaSDR) rule. To
facilitate the efforts of EPA, other
Federal and State agencies, interested
stakeholders and members of the public
in obtaining basic health effects and
environmental data on HPV chemicals,
the ITC conducted a December 2004
data-availability study of 235 substances
that were HPV chemicals in the 1998
and 2002 Inventory Update Rules
(IURs), but not in the 1990 or 1994 IURs.
The study is discussed and the list of
235 substances is appended to this 56th
ITC Report.

I. Background
The ITC was established by section
4(e) of TSCA ‘‘to make
recommendations to the Administrator
respecting the chemical substances and
mixtures to which the Administrator
should give priority consideration for
the promulgation of rules for testing
under section 4(a).... At least every six
months ..., the Committee shall make
such revisions to the Priority Testing
List as it determines to be necessary and
transmit them to the Administrator
together with the Committee’s reasons
VerDate Aug<31>2005

for the revisions’’ (Public Law 94–469,
90 Stat. 2003 et seq., 15 U.S.C. 2601 et
seq.). ITC reports are available from the
ITC’s web site (https://www.epa.gov/
opptintr/itc) within a few days of
submission to the Administrator and
from the EPA’s web site (https://
www.epa.gov/fedrgstr) after publication
in the Federal Register. The ITC
produces its revisions to the Priority
Testing List with administrative and
technical support from the ITC staff, ITC
members and their U.S. Government
organizations, and contract support

II. TSCA Section 8 Reporting
A. TSCA Section 8 Reporting Rules
Following receipt of the ITC’s report
(and the revised Priority Testing List) by
the EPA Administrator, the EPA’s Office
of Pollution Prevention and Toxics
(OPPT) may add the chemicals from the
revised Priority Testing List to the TSCA
section 8(a) PAIR or TSCA section 8(d)
HaSDR rules. The PAIR rule requires
manufacturers (including importers) of
E:\FR\FM\24OCN4.SGM
24OCN4
Federal Register / Vol. 70, No. 204 / Monday, October 24, 2005 / Notices
chemicals added to the Priority Testing
List to submit production and exposure
reports (https://www.epa.gov/opptintr/
chemtest/pairform.pdf). The HaSDR
rule requires manufacturers (including
importers) of chemicals added to the
Priority Testing List to submit
unpublished health and safety studies
under TSCA section 8(d) that must be in
compliance with the revised HaSDR
rule (Ref. 1). All submissions to both
rules must be received by the EPA
within 90 days of the reporting rules’
Federal Register publication date, i.e.,
60 days from the reporting rules’
effective date, because 30 days are
allowed for public comment.
B. ITC’s Use of TSCA Section 8 and
Other Information
The ITC’s use of TSCA section 8 and
other information is described in the
52nd ITC Report (https://www.epa.gov/
opptintr/itc/rptmain.htm).
C. Previous Requests to Add Chemicals
to the TSCA Section 8(a) PAIR and
Section 8(d) HaSDR Rules
In its December 8, 2004, 55th ITC
Report to the EPA Administrator, the
ITC added 276 HPV Challenge Program
Orphan chemicals to the Priority Testing
List, and requested that EPA add them
to TSCA section 8(a) PAIR and 8(d)
HaSDR rules. HPV Challenge Program
chemicals are those with U.S. annual
production or importation volumes of 1
million pounds or more reported to EPA
in the 1990 IUR (https://www.epa.gov/
opptintr/chemrtk/hpv_1990.htm)
supplemented with additional HPV
chemicals from the 1994 IUR (https://
www.epa.gov/opptintr/chemrtk/
hpv_1994.htm). HPV orphan chemicals
are those for which companies have not
made commitments under the EPA’s
HPV Challenge Program to prepare
Robust Summaries, sponsor testing, etc.
On February 11, 2005, the 55th ITC
Report was published in the Federal
Register and included 270 HPV orphan
chemicals (Ref 2). The smaller number
of HPV orphan chemicals (270) in the
Federal Register version of the 55th ITC
Report was attributed to new
commitments for 6 HPV orphan
chemicals made by companies under
the HPV Challenge Program.
As noted in section IV.B.1.,
commitments for 2 of the 6 HPV orphan
chemicals, ethanol, 2-methoxy(Chemical Abstracts Service Registry
Number (CAS No.) 109–86–4) and
tetradecane (CAS No. 629–59–4) were
transferred to the International Council
of Chemical Association (ICCA) HPV
Initiative. As a result, these 2 HPV
orphan chemicals will not be added to
TSCA section 8(a) PAIR and 8(d) HaSDR
VerDate Aug<31>2005
15:25 Oct 21, 2005
Jkt 208001
rules and are not included in Appendix
A.
However, 4 of the 6 HPV orphan
chemicals that were not included in the
February 11, 2005 Federal Register
notice are being retained on the
December 8, 2004 Priority Testing List
and added back to the February 11, 2005
Priority Testing List because these new
commitments were received by EPA
after December 8, 2004 (Table 2 of this
section).
61523
commitments from U.S. manufacturers
and importers of HPV chemicals and
defines specific timelines for submitting
test plans and robust summaries.
At this time, the 8 HPV orphan
chemicals in Tables 2 and 3 of this
section will not be added to TSCA
section 8(a) PAIR and 8(d) HaSDR rules
and are not included in Appendix A.
However, maintaining these 8 HPV
orphan chemicals on the Priority Testing
List will ensure that recourse to future
TSCA 8(a) and 8(d) rules can address
those chemicals for which commitments
are not met according to the June 27,
2005 policy.

section 8(d) HaSDR rules. The ITC
requests that tungsten oxides, W10O29
(CAS No. 12037–58–0) and W18O49
(CAS No. 12037–57–9), be added to a
different TSCA section 8(a) PAIR rule
than the HPV orphan chemicals.
III. ITC’s Activities During this
Reporting Period (December 2004 to
August 2005)
A. Status of HPV Challenge Program
Orphan Chemicals
During this reporting period, the ITC
Director met with EPA to discuss the
EPA Policy Regarding Acceptance of
New Commitments to Sponsor
Chemicals under the HPV Challenge
Program (https://www.epa.gov/chemrtk/
hpvpolcy.htm). Under this Policy, EPA
will accept new commitments for the
243 HPV orphan chemicals listed in
Appendix A. Appendix A includes the
5 HPV orphan chemicals discussed in
section IV.A.1., but not the 2 HPV
orphan chemicals transferred to the
ICCA HPV Initiative, the 8 HPV orphan
chemicals in Tables 2 and 3, and the 28
HPV orphan chemicals discussed in
section IV.B.1. EPA will accept new
commitments from the date the ITC
submitted its 55th ITC Report to the EPA
Administrator (i.e., December 8, 2004)
until 14 days following publication of
the TSCA section 8(a) PAIR and 8(d)
HaSDR rules for the 243 HPV orphan
chemicals listed in Appendix A. HPV
orphan chemicals for which new
commitments are accepted based on
EPA’s policy will either not be included
in or will be removed from the 8(a)
PAIR and 8(d) HaSDR rules prior to
their effective dates.
In contrast to Appendix A, the

chemicals in Tables 2 and 3, but not the
2 HPV orphan chemicals transferred to
the ICCA HPV Initiative and the 28 HPV
orphan chemicals discussed in section
IV.B.1. for a total of 246 HPV orphan
chemicals. With the addition of the 5
HPV orphan chemicals discussed in
section IV.A.1., there are a total of 251
HPV orphan chemicals on the Priority
Testing List.
B. Data-Availability Study for HPV
Chemicals in the 1998 and 2002 IURs,
But Not in the 1990 or 1994 IURs
To facilitate the efforts of EPA, other
Federal and State agencies, interested
stakeholders and members of the public
in obtaining basic health effects and
environmental data on HPV chemicals,
the ITC conducted a data-availability
study in December 2004. The study
focused on 235 substances that were
HPV chemicals in the 1998 and 2002
IURs, but not in the 1990 or 1994 IURs.
The HPV status of these chemicals was
confirmed on May 25, 2005. Since the
ITC conducted its study, the American
Chemistry Council (ACC), Soap and
Detergent Association (SDA) and
Synthetic Organic Chemical
Manufacturers Association (SOCMA)
announced its Extended HPV (EHPV)
Program on March 15, 2005. The goal of
the EHPV Program is to collect and
publish health and environmental
information on approximately 500
chemicals that did not qualify as HPV
chemicals under the EPA’s original HPV
Challenge program but have since
reached the 1 million pound per year
threshold according to the 2002 IUR.
The ITC is making the results of the
study available in this 56th ITC Report
to provide the ACC, SDA, SOCMA, and
others involved in the industry-led
EHPV Program with information that
will assist these organizations in
determining if there are existing
unpublished studies that can provide
the basic health and environmental
effects data on these HPV chemicals.To
complement the data-availability study
of 235 HPV chemicals included in both
the 1998 and 2002 IURs, the ITC
conducted a data-availability study in
August 2005 of about 284 additional
chemicals that were HPV chemicals
only in the 2002 IUR but not in the
1990, 1994 or 1998 IURs. None of these
284 chemicals were included in the
data-availability study of 235 HPV
chemicals in the 1998 and 2002 IURs.
The ITC will make the results of this
study public in its 57th ITC Report to the
EPA Administrator. In addition, the ITC
has initiated data-availability studies on
categories of non-HPV chemicals and
will make the results of these studies
VerDate Aug<31>2005
15:25 Oct 21, 2005
Jkt 208001
public in future reports to the EPA
Administrator. At this time, the ITC has
not determined whether to conduct a
data-availability study on approximately
237 chemicals that were HPV chemicals
only in the 1998 IUR, but not in the
1990, 1994 or 2002 IURs, because the
ITC wants to review the 2006 IUR data
for these chemicals. The goal of the
ITC’s data-availability studies is to
provide tools for ACC, SDA, SOCMA,
and other stakeholders to use in efforts
to provide information on publicly
available studies for IUR chemicals.
The data-availability study of the 235
substances that were HPV chemicals in
the 1998 and 2002 IURs, but not in the
1990 or 1994 IURs was based on the
methods that EPA used for assessing the
availability of data for the 1990 HPV
Challenge Program List of Chemicals
(see https://www.epa.gov/chemrtk/
hazchem.pdf), but was expanded to
include studies sponsored by the NTP
(https://ntp-server.niehs.nih.gov/). The
methods that EPA used for the 1990
HPV chemicals were designed to
determine if there were available studies
for 6 endpoints that were required for
the Organization for Economic
Cooperation and Development (OECD)
Screening Information Data Set (SIDS)
dossiers. These 6 endpoints included 4
health-effects related endpoints (acute
toxicity, chronic toxicity, mutagenicity,
reproductive effects/developmental
toxicity), an ecological effects endpoint
and an environmental fate endpoint.
Expanding the EPA methods to include
NTP studies provided opportunities to
capture studies on other health-effects
related endpoints (e.g., neurotoxicity
and carcinogenicity) and on the 4
health-effects related endpoints that
might not be included in information
sources that were searched. The results
of the data-availability study of the 235
substances that were HPV chemicals in
the 1998 and 2002 IURs, but not in the
1990 or 1994 IURs are summarized in
Table 4 of this section.

C. Status of Requests for Data on
Vanadium Compounds in Surface
Impoundments
As discussed in the 55th ITC Report,
the ITC is concerned that vanadium
compounds may be released into fly ash
ponds and related impoundments and
could be toxic to avian and wildlife
species as exemplified by a recent report
of dead Canada geese at a petroleum
refinery fly ash pond in Delaware.
During this reporting period, the ITC
contacted the ACC, American Petroleum
Institute (API), Electric Power Research
Institute (EPRI), Alabama Power
Company, Barrick Goldstrike Mines,
Kerr-McGee Chemical, Newmont
Mining Corporation and U.S. Vanadium
Corporation to determine if these
organizations could provide data on
concentrations and species of vanadium
compounds in surface impoundments
(fluid-filled depressions). The API
reported that one of their members
found less than 1 part per billion (ppb)
vanadium in their waste ponds. EPRI
suggested that higher concentrations of
vanadium compounds are likely to be
found in fly-ash ponds at coal-fired
power plants than at other electricitygenerating facilities, but that
concentrations in ponds would likely
range from 10 to 100 ppb vanadium.
From the companies listed above, none
reported vanadium concentrations as
high as the 478,000 ppb vanadium in
the Delaware petroleum refinery fly ash
pond.

Priority Testing List
A. Chemicals Added to the Priority
Testing List
1. HPV orphan chemicals. Naphtha
(petroleum), clay-treated light straightrun (CAS No. 68527–22–0) is being
added to the Priority Testing List
because it was inadvertently left off the
original list of HPV orphan chemicals
that were HPV chemicals in either the
1998 or 2002 IURs (Table 5 of this
section). EPA has confirmed that this
chemical was produced at HPV volumes
in 2002. Four additional HPV orphan
chemicals are being added because
previous sponsors withdrew their
sponsorship commitments (Table 5 of
this section).

to meet U.S. Government data needs
(Ref. 3). In this 56th ITC Report, the ITC
is adding tungsten oxide (W18O49) (CAS
No. 12037–57–9) and tungsten oxide
(W10O29) (CAS No. 12037–58–0) to the
Priority Testing List and is soliciting
information on health effects and
occupational exposures.
B. Chemicals Removed from the Priority
Testing List
1. HPV orphan chemicals. The ITC is
removing ethanol, 2-methoxy- (CAS No.
109–86–4) and tetradecane (CAS No.
629–59–4) from the December 8, 2004
Priority Testing List because
sponsorship of these two substances
was transferred to the ICCA HPV
Initiative. The ITC is removing 11 HPV
orphan chemicals from the December 8,

effects information to meet U.S.
Government data needs (Ref. 3). Since
then, the ITC has reviewed reports
submitted in response to the December
7, 2004 PAIR rule (Ref. 4). In this 56th
ITC Report, the ITC is removing 2pyridinamine (CAS No. 504–29–0), 3pyridinamine (CAS No. 462–08–8) and
4-pyridinamine (CAS No. 504–24–5)
from the Priority Testing List because
information submitted in response to
the PAIR rule suggested low potential
for occupational exposure.
3. Indium compounds. In its 47th ITC
Report, the ITC added 37 indium
compounds to the Priority Testing List
to obtain importation, production, use,
exposure, and health effects information
to meet U.S. Government data needs
(Ref. 5). Twenty-eight indium

compounds were removed from the
Priority Testing List because no
production or importation data were
submitted to EPA in response to the July
26, 2001, PAIR rule (Ref. 6). These 28
indium compounds are listed in the 51st
ITC Report (Ref. 7). The remaining 9
indium compounds were added to the
May 4, 2004 TSCA section 8(d) HaSDR
rule (Ref. 8). In this 56th ITC Report, the
ITC is removing 6 indium compounds
from the Priority Testing List because
information submitted in response to
the PAIR rule suggested low potential
for occupational exposure and because
only one study was submitted in
response to the HaSDR rule (Table 8 of
this section).

its 54th ITC Report, the ITC removed 25
vanadium compounds from the Priority
Testing List because information
submitted in response to the PAIR rule
suggested low potential for occupational
exposure (Ref. 10).
At this time, the ITC needs data on
water and sediment concentrations of
vanadium species in fly ash ponds and
related impoundments (fluid-filled
depressions) and the pH of these ponds
and impoundments. In addition, the ITC
needs information on any wildlife
mortality events occurring near these
impoundments. A recent study that
described the toxicity and hazard of
vanadium to mallard ducks and Canada
geese was conducted because of wildlife
mortalities that occurred in a Delaware
oil refinery fly ash pond contaminated
with vanadium compounds (Ref. 11).
In this 56th ITC Report, the ITC is
removing 6 vanadium compounds from
the Priority Testing List (Table 10 of this
section).

which workers may be exposed during
manufacturing and downstream uses
and 2) numbers of workers associated
with manufacturing and downstream
uses. The ITC needs this information to
assess occupational exposures.
4. Vanadium compounds. In its 51st
ITC Report, the ITC added 43 vanadium
compounds to the Priority Testing List
to obtain importation, production, use,
exposure, and health effects information
to meet U.S. Government data needs
15:25 Oct 21, 2005

27774–13–6) from the Priority Testing
List because information submitted in
response to the PAIR rule suggested low
potential for occupational exposure. The
ITC is removing vanadium carbide (CAS
No. 11130–21–5) and vanadium
hydroxide oxide phosphate (CAS No.

Fifty-Sixth Report of the TSCA Interagency Testing Committee to
the Administrator of the Environmental Protection Agency; Receipt of
Report and Request for Comments
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Toxic Substances Control Act (TSCA) Interagency Testing
Committee (ITC) transmitted its 56\th\ ITC Report to the Administrator
of EPA on September 15, 2005. In the 56\th\ ITC Report, which is
included with this notice, the ITC is revising the TSCA section 4(e)
Priority Testing List by adding 5 High Production Volume (HPV) orphan
chemicals and 2 tungsten compounds and removing 28 HPV orphan
chemicals, 3 pyridinamine compounds, 6 indium compounds, and 6 vanadium
compounds. The ITC is requesting that EPA add the 5 HPV orphan
chemicals and 2 tungsten compounds to the TSCA section 8(a) Preliminary
Assessment Information Reporting (PAIR) rule and the 5 HPV orphan
chemicals to the TSCA section 8(d) Health and Safety Data Reporting
(HaSDR) rule. To facilitate the efforts of EPA, other Federal and State
agencies, interested stakeholders, and members of the public in
obtaining basic health effects and environmental data on HPV chemicals,
the ITC conducted a December 2004 Data-Availability Study of 235
substances that were HPV chemicals in the 1998 and 2002 Inventory
Update Rules (IURs), but not in the 1990 or 1994 IURs. The study is
discussed and the list of 235 substances is appended to this 56\th\ ITC
Report.
DATES: Comments must be received on or before November 23, 2005.
ADDRESSES: Comments, identified by docket identification (ID) number
OPPT-2005-0039, may be submitted electronically, by mail, or through
hand delivery/courier. Follow the detailed instructions as provided in
Unit I. of the SUPPLEMENTARY INFORMATION.

Certain types of information will not be placed in the EPA Dockets.
Information claimed as CBI and other information whose disclosure is
restricted by statute, which is not included in the official public
docket, will not be available for public viewing in EPA's electronic
public docket. EPA's policy is that copyrighted material will not be
placed in EPA's electronic public docket but will be available only in
printed, paper form in the official public docket. To the extent
feasible, publicly available docket materials will be made available in
EPA's electronic public docket. When a document is selected from the
index list in EPA Dockets, the system will identify whether the
document is available for viewing in EPA's electronic public docket.
Although not all docket materials may be available electronically, you
may still access any of the publicly available docket materials through
the docket facility identified in Unit I.B.1. EPA intends to work
towards providing electronic access to all of the publicly available
docket materials through EPA's electronic public docket.
For public commenters, it is important to note that EPA's policy is
that public comments, whether submitted electronically or in paper,
will be made available for public viewing in EPA's electronic public
docket as EPA receives them and without change, unless the comment
contains copyrighted material, CBI, or other information whose
disclosure is restricted by statute. When EPA identifies a comment
containing copyrighted material, EPA will provide a reference to that
material in the version of the comment that is placed in EPA's
electronic public docket. The entire printed comment, including the
copyrighted material, will be available in the public docket.
Public comments submitted on computer disks that are mailed or
delivered to the docket will be transferred to EPA's electronic public
docket. Public comments that are mailed or delivered to the docket will
be scanned and placed in EPA's electronic public docket. Where
practical, physical objects will be photographed, and the
[[Page 61521]]
photograph will be placed in EPA's electronic public docket along with
a brief description written by the docket staff.
C. How and to Whom Do I Submit Comments?
You may submit comments electronically, by mail, or through hand
delivery/courier. To ensure proper receipt by EPA, identify the
appropriate docket ID number in the subject line on the first page of
your comment. Please ensure that your comments are submitted within the
specified comment period. Comments received after the close of the
comment period will be marked ``late.'' EPA is not required to consider
these late comments. If you wish to submit CBI or information that is
otherwise protected by statute, please follow the instructions in Unit
I.D. Do not use EPA Dockets or e-mail to submit CBI or information
protected by statute.
1. Electronically. If you submit an electronic comment as
prescribed in this unit, EPA recommends that you include your name,
mailing address, and an e-mail address or other contact information in
the body of your comment. Also include this contact information on the
outside of any disk or CD ROM you submit, and in any cover letter
accompanying the disk or CD ROM. This ensures that you can be
identified as the submitter of the comment and allows EPA to contact
you in case EPA cannot read your comment due to technical difficulties
or needs further information on the substance of your comment. EPA's
policy is that EPA will not edit your comment, and any identifying or
contact information provided in the body of a comment will be included
as part of the comment that is placed in the official public docket,
and made available in EPA's electronic public docket. If EPA cannot
read your comment due to technical difficulties and cannot contact you
for clarification, EPA may not be able to consider your comment.
i. EPA Dockets. Your use of EPA's electronic public docket to
submit comments to EPA electronically is EPA's preferred method for
receiving comments. Go directly to EPA Dockets at https://www.epa.gov/
edocket/, and follow the online instructions for submitting comments.
Once in the system, select ``search,'' and then key in docket ID number
OPPT-2005-0039. The system is an ``anonymous access'' system, which
means EPA will not know your identity, e-mail address, or other contact
information unless you provide it in the body of your comment.
ii. E-mail. Comments may be sent by e-mail to oppt.ncic@epa.gov,
Attention: Docket ID Number OPPT-2005-0039. In contrast to EPA's
electronic public docket, EPA's e-mail system is not an ``anonymous
access'' system. If you send an e-mail comment directly to the docket
without going through EPA's electronic public docket, EPA's e-mail
system automatically captures your e-mail address. E-mail addresses
that are automatically captured by EPA's e-mail system are included as
part of the comment that is placed in the official public docket, and
made available in EPA's electronic public docket.
iii. Disk or CD ROM. You may submit comments on a disk or CD ROM
that you mail to the mailing address identified in Unit I.C.2. These
electronic submissions will be accepted in WordPerfect or ASCII file
format. Avoid the use of special characters and any form of encryption.
2. By mail. Send your comments to: Document Control Office (7407M),
Office of Pollution Prevention and Toxics (OPPT), Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001.
3. By hand delivery or courier. Deliver your comments to: OPPT
Document Control Office (DCO), EPA East Bldg., Rm. 6428, 1201
Constitution Ave., NW., Washington, DC. Attention: Docket ID Number

(202) 564-8930.
D. How Should I Submit CBI to the Agency?
Do not submit information that you consider to be CBI
electronically through EPA's electronic public docket or by e-mail. You
may claim information that you submit to EPA as CBI by marking any part
or all of that information as CBI (if you submit CBI on disk or CD ROM,
mark the outside of the disk or CD ROM as CBI and then identify
electronically within the disk or CD ROM the specific information that
is CBI). Information so marked will not be disclosed except in
accordance with procedures set forth in 40 CFR part 2.
In addition to one complete version of the comment that includes
any information claimed as CBI, a copy of the comment that does not
contain the information claimed as CBI must be submitted for inclusion
in the public docket and EPA's electronic public docket. If you submit
the copy that does not contain CBI on disk or CD ROM, mark the outside
of the disk or CD ROM clearly that it does not contain CBI. Information
not marked as CBI will be included in the public docket and EPA's
electronic public docket without prior notice. If you have any
questions about CBI or the procedures for claiming CBI, please consult
the person listed under FOR FURTHER INFORMATION CONTACT.

II. Background
The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.)
authorizes the Administrator of EPA to promulgate regulations under
TSCA section 4(a) requiring testing of chemicals and chemical groups in
order to develop data relevant to determining the risks that such
chemicals and chemical groups may present to health or the environment.
Section 4(e) of TSCA established the ITC to recommend chemicals and
chemical groups to the Administrator of EPA for priority testing
consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA
section 4(e) Priority Testing List at least every 6 months.

I. Background
The ITC was established by section 4(e) of TSCA ``to make
recommendations to the Administrator respecting the chemical substances
and mixtures to which the Administrator should give priority
consideration for the promulgation of rules for testing under section
4(a).... At least every six months ..., the Committee shall make such
revisions to the Priority Testing List as it determines to be necessary
and transmit them to the Administrator together with the Committee's
reasons for the revisions'' (Public Law 94-469, 90 Stat. 2003 et seq.,
15 U.S.C. 2601 et seq.). ITC reports are available from the ITC's web
site (https://www.epa.gov/opptintr/itc) within a few days of submission
to the Administrator and from the EPA's web site (https://www.epa.gov/
fedrgstr) after publication in the Federal Register. The ITC produces
its revisions to the Priority Testing List with administrative and
technical support from the ITC staff, ITC members and their U.S.
Government organizations, and contract support provided by EPA. ITC
members and staff are listed at the end of this report.
II. TSCA Section 8 Reporting
A. TSCA Section 8 Reporting Rules
Following receipt of the ITC's report (and the revised Priority
Testing List) by the EPA Administrator, the EPA's Office of Pollution
Prevention and Toxics (OPPT) may add the chemicals from the revised
Priority Testing List to the TSCA section 8(a) PAIR or TSCA section
8(d) HaSDR rules. The PAIR rule requires manufacturers (including
importers) of
[[Page 61523]]
chemicals added to the Priority Testing List to submit production and
exposure reports (https://www.epa.gov/opptintr/chemtest/pairform.pdf).
The HaSDR rule requires manufacturers (including importers) of
chemicals added to the Priority Testing List to submit unpublished
health and safety studies under TSCA section 8(d) that must be in
compliance with the revised HaSDR rule (Ref. 1). All submissions to
both rules must be received by the EPA within 90 days of the reporting
rules' Federal Register publication date, i.e., 60 days from the
reporting rules' effective date, because 30 days are allowed for public
comment.
B. ITC's Use of TSCA Section 8 and Other Information
The ITC's use of TSCA section 8 and other information is described
in the 52\nd\ ITC Report (https://www.epa.gov/opptintr/itc/rptmain.htm).
C. Previous Requests to Add Chemicals to the TSCA Section 8(a) PAIR and
Section 8(d) HaSDR Rules
In its December 8, 2004, 55\th\ ITC Report to the EPA
Administrator, the ITC added 276 HPV Challenge Program Orphan chemicals
to the Priority Testing List, and requested that EPA add them to TSCA
section 8(a) PAIR and 8(d) HaSDR rules. HPV Challenge Program chemicals
are those with U.S. annual production or importation volumes of 1
million pounds or more reported to EPA in the 1990 IUR (https://
www.epa.gov/opptintr/chemrtk/hpv_1990.htm) supplemented with
additional HPV chemicals from the 1994 IUR (https://www.epa.gov/
opptintr/chemrtk/hpv_1994.htm). HPV orphan chemicals are those for
which companies have not made commitments under the EPA's HPV Challenge
Program to prepare Robust Summaries, sponsor testing, etc.
On February 11, 2005, the 55\th\ ITC Report was published in the
Federal Register and included 270 HPV orphan chemicals (Ref 2). The
smaller number of HPV orphan chemicals (270) in the Federal Register
version of the 55\th\ ITC Report was attributed to new commitments for
6 HPV orphan chemicals made by companies under the HPV Challenge
Program.
As noted in section IV.B.1., commitments for 2 of the 6 HPV orphan
chemicals, ethanol, 2-methoxy- (Chemical Abstracts Service Registry
Number (CAS No.) 109-86-4) and tetradecane (CAS No. 629-59-4) were
transferred to the International Council of Chemical Association (ICCA)
HPV Initiative. As a result, these 2 HPV orphan chemicals will not be
added to TSCA section 8(a) PAIR and 8(d) HaSDR rules and are not
included in Appendix A.
However, 4 of the 6 HPV orphan chemicals that were not included in
the February 11, 2005 Federal Register notice are being retained on the
December 8, 2004 Priority Testing List and added back to the February
11, 2005 Priority Testing List because these new commitments were
received by EPA after December 8, 2004 (Table 2 of this section).

In addition, there are 4 HPV orphan chemicals that are being
retained on the December 8, 2004 and February 11, 2005 Priority Testing
List because these new commitments were also received by EPA after
December 8, 2004 (Table 3 of this section).

The commitments for the 8 HPV orphan chemicals in Tables 2 and 3 of
this section are being treated as new commitments in accordance with
EPA's Policy Regarding Acceptance of New Commitments to Sponsor
Chemicals under the HPV Challenge Program. The June 27, 2005 policy is
described in https://www.epa.gov/chemrtk/hpvpolcy.htm and outlines a
process by which EPA continues to encourage commitments from U.S.
manufacturers and importers of HPV chemicals and defines specific
timelines for submitting test plans and robust summaries.
At this time, the 8 HPV orphan chemicals in Tables 2 and 3 of this
section will not be added to TSCA section 8(a) PAIR and 8(d) HaSDR
rules and are not included in Appendix A. However, maintaining these 8
HPV orphan chemicals on the Priority Testing List will ensure that
recourse to future TSCA 8(a) and 8(d) rules can address those chemicals
for which commitments are not met according to the June 27, 2005
policy.
D. New Requests to Add Chemicals to the TSCA Section 8(a) PAIR and
Section 8(d) HaSDR Rules
In this report, the ITC is requesting that EPA add the 5 HPV orphan
chemicals discussed in section IV.A.1. to the TSCA section 8(a) PAIR
and section 8(d) HaSDR rules. The ITC requests that tungsten oxides,
W10O29 (CAS No. 12037-58-0) and
W18O49 (CAS No. 12037-57-9), be added to a
different TSCA section 8(a) PAIR rule than the HPV orphan chemicals.
III. ITC's Activities During this Reporting Period (December 2004 to
August 2005)
A. Status of HPV Challenge Program Orphan Chemicals
During this reporting period, the ITC Director met with EPA to
discuss the EPA Policy Regarding Acceptance of New Commitments to
Sponsor Chemicals under the HPV Challenge Program (https://www.epa.gov/
chemrtk/hpvpolcy.htm). Under this Policy, EPA will accept new
commitments for the 243 HPV orphan chemicals listed in Appendix A.
Appendix A includes the 5 HPV orphan chemicals discussed in section
IV.A.1., but not the 2 HPV orphan chemicals transferred to the ICCA HPV
Initiative, the 8 HPV orphan chemicals in Tables 2 and 3, and the 28
HPV orphan chemicals discussed in section IV.B.1. EPA will accept new
commitments from the date the ITC submitted its 55\th\ ITC Report to
the EPA Administrator (i.e., December 8, 2004) until 14 days following
publication of the TSCA section 8(a) PAIR and 8(d) HaSDR rules for the
243 HPV orphan chemicals listed in Appendix A. HPV orphan chemicals for
which new commitments are accepted based on EPA's policy will either
not be included in or will be removed from the 8(a) PAIR and 8(d) HaSDR
rules prior to their effective dates.
In contrast to Appendix A, the Priority Testing List from the
55\th\ ITC
[[Page 61524]]
Report includes the 8 HPV orphan chemicals in Tables 2 and 3, but not
the 2 HPV orphan chemicals transferred to the ICCA HPV Initiative and
the 28 HPV orphan chemicals discussed in section IV.B.1. for a total of
246 HPV orphan chemicals. With the addition of the 5 HPV orphan
chemicals discussed in section IV.A.1., there are a total of 251 HPV
orphan chemicals on the Priority Testing List.
B. Data-Availability Study for HPV Chemicals in the 1998 and 2002 IURs,
But Not in the 1990 or 1994 IURs
To facilitate the efforts of EPA, other Federal and State agencies,
interested stakeholders and members of the public in obtaining basic
health effects and environmental data on HPV chemicals, the ITC
conducted a data-availability study in December 2004. The study focused
on 235 substances that were HPV chemicals in the 1998 and 2002 IURs,
but not in the 1990 or 1994 IURs. The HPV status of these chemicals was
confirmed on May 25, 2005. Since the ITC conducted its study, the
American Chemistry Council (ACC), Soap and Detergent Association (SDA)
and Synthetic Organic Chemical Manufacturers Association (SOCMA)
announced its Extended HPV (EHPV) Program on March 15, 2005. The goal
of the EHPV Program is to collect and publish health and environmental
information on approximately 500 chemicals that did not qualify as HPV
chemicals under the EPA's original HPV Challenge program but have since
reached the 1 million pound per year threshold according to the 2002
IUR.
The ITC is making the results of the study available in this 56\th\
ITC Report to provide the ACC, SDA, SOCMA, and others involved in the
industry-led EHPV Program with information that will assist these
organizations in determining if there are existing unpublished studies
that can provide the basic health and environmental effects data on
these HPV chemicals.To complement the data-availability study of 235
HPV chemicals included in both the 1998 and 2002 IURs, the ITC
conducted a data-availability study in August 2005 of about 284
additional chemicals that were HPV chemicals only in the 2002 IUR but
not in the 1990, 1994 or 1998 IURs. None of these 284 chemicals were
included in the data-availability study of 235 HPV chemicals in the
1998 and 2002 IURs. The ITC will make the results of this study public
in its 57\th\ ITC Report to the EPA Administrator. In addition, the ITC
has initiated data-availability studies on categories of non-HPV
chemicals and will make the results of these studies public in future
reports to the EPA Administrator. At this time, the ITC has not
determined whether to conduct a data-availability study on
approximately 237 chemicals that were HPV chemicals only in the 1998
IUR, but not in the 1990, 1994 or 2002 IURs, because the ITC wants to
review the 2006 IUR data for these chemicals. The goal of the ITC's
data-availability studies is to provide tools for ACC, SDA, SOCMA, and
other stakeholders to use in efforts to provide information on publicly
available studies for IUR chemicals.
The data-availability study of the 235 substances that were HPV
chemicals in the 1998 and 2002 IURs, but not in the 1990 or 1994 IURs
was based on the methods that EPA used for assessing the availability
of data for the 1990 HPV Challenge Program List of Chemicals (see
https://www.epa.gov/chemrtk/hazchem.pdf), but was expanded to include
studies sponsored by the NTP (https://ntp-server.niehs.nih.gov/). The
methods that EPA used for the 1990 HPV chemicals were designed to
determine if there were available studies for 6 endpoints that were
required for the Organization for Economic Cooperation and Development
(OECD) Screening Information Data Set (SIDS) dossiers. These 6
endpoints included 4 health-effects related endpoints (acute toxicity,
chronic toxicity, mutagenicity, reproductive effects/developmental
toxicity), an ecological effects endpoint and an environmental fate
endpoint. Expanding the EPA methods to include NTP studies provided
opportunities to capture studies on other health-effects related
endpoints (e.g., neurotoxicity and carcinogenicity) and on the 4
health-effects related endpoints that might not be included in
information sources that were searched. The results of the data-
availability study of the 235 substances that were HPV chemicals in the
1998 and 2002 IURs, but not in the 1990 or 1994 IURs are summarized in
Table 4 of this section.

1994 IURs are listed in Appendix B. A table identifying the publicly
available studies for the 235 HPV chemicals in the 1998 and 2002 IURs
is posted on the ITC's web site (https://www.epa.gov/opptintr/itc).
C. Status of Requests for Data on Vanadium Compounds in Surface
Impoundments
As discussed in the 55\th\ ITC Report, the ITC is concerned that
vanadium compounds may be released into fly ash ponds and related
impoundments and could be toxic to avian and wildlife species as
exemplified by a recent report of dead Canada geese at a petroleum
refinery fly ash pond in Delaware. During this reporting period, the
ITC contacted the ACC, American Petroleum Institute (API), Electric
Power Research Institute (EPRI), Alabama Power Company, Barrick
Goldstrike Mines, Kerr-McGee Chemical, Newmont Mining Corporation and
U.S. Vanadium Corporation to determine if these organizations could
provide data on concentrations and species of vanadium compounds in
surface impoundments (fluid-filled depressions). The API reported that
one of their members found less than 1 part per billion (ppb) vanadium
in their waste ponds. EPRI suggested that higher concentrations of
vanadium compounds are likely to be found in fly-ash ponds at coal-
fired power plants than at other electricity-generating facilities, but
that concentrations in ponds would likely range from 10 to 100 ppb
vanadium. From the companies listed above, none reported vanadium
concentrations as high as the 478,000 ppb vanadium in the Delaware
petroleum refinery fly ash pond.
[[Page 61525]]
IV. Revisions to the TSCA Section 4(e) Priority Testing List
A. Chemicals Added to the Priority Testing List
1. HPV orphan chemicals. Naphtha (petroleum), clay-treated light
straight-run (CAS No. 68527-22-0) is being added to the Priority
Testing List because it was inadvertently left off the original list of
HPV orphan chemicals that were HPV chemicals in either the 1998 or 2002
IURs (Table 5 of this section). EPA has confirmed that this chemical
was produced at HPV volumes in 2002. Four additional HPV orphan
chemicals are being added because previous sponsors withdrew their
sponsorship commitments (Table 5 of this section).
Table 5.--HPV Orphan Chemicals Being Added to the Priority Testing List
in this 56\th\ ITC Report
------------------------------------------------------------------------

-------------------------------------------
72162-15-3 1-Decene, sulfurized
------------------------------------------------------------------------
2. Tungsten compounds.In its 53\rd\ ITC Report, the ITC added 20
tungsten compounds to the Priority Testing List to obtain importation,
production, use, exposure, and health effects information to meet U.S.
Government data needs (Ref. 3). In this 56\th\ ITC Report, the ITC is
adding tungsten oxide (W18O49) (CAS No. 12037-57-
9) and tungsten oxide (W10O29) (CAS No. 12037-58-
0) to the Priority Testing List and is soliciting information on health
effects and occupational exposures.
B. Chemicals Removed from the Priority Testing List
1. HPV orphan chemicals. The ITC is removing ethanol, 2-methoxy-
(CAS No. 109-86-4) and tetradecane (CAS No. 629-59-4) from the December
8, 2004 Priority Testing List because sponsorship of these two
substances was transferred to the ICCA HPV Initiative. The ITC is
removing 11 HPV orphan chemicals from the December 8, 2004 Priority
Testing List that were sponsored before the 55\th\ ITC Report was sent
to the EPA Administrator on December 8, 2004 (Table 6 of this section).

2. Pyridinamine compounds. In its 53\rd\ ITC Report, the ITC added
3 pyridinamine compounds to the Priority Testing List to obtain
importation, production, use, exposure, and health effects information
to meet U.S. Government data needs (Ref. 3). Since then, the ITC has
reviewed reports submitted in response to the December 7, 2004 PAIR
rule (Ref. 4). In this 56\th\ ITC Report, the ITC is removing 2-
pyridinamine (CAS No. 504-29-0), 3-pyridinamine (CAS No. 462-08-8) and
4-pyridinamine (CAS No. 504-24-5) from the Priority Testing List
because information submitted in response to the PAIR rule suggested
low potential for occupational exposure.
3. Indium compounds. In its 47\th\ ITC Report, the ITC added 37
indium compounds to the Priority Testing List to obtain importation,
production, use, exposure, and health effects information to meet U.S.
Government data needs (Ref. 5). Twenty-eight indium
[[Page 61526]]
compounds were removed from the Priority Testing List because no
production or importation data were submitted to EPA in response to the
July 26, 2001, PAIR rule (Ref. 6). These 28 indium compounds are listed
in the 51\st\ ITC Report (Ref. 7). The remaining 9 indium compounds
were added to the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 8). In
this 56\th\ ITC Report, the ITC is removing 6 indium compounds from the
Priority Testing List because information submitted in response to the
PAIR rule suggested low potential for occupational exposure and because
only one study was submitted in response to the HaSDR rule (Table 8 of
this section).

22398-80-7 Indium phosphide (InP)
-------------------------------------------
50926-11-9 Indium tin oxide.
------------------------------------------------------------------------
For these 3 indium compounds, the ITC needs data on: 1)
concentrations to which workers may be exposed during manufacturing and
downstream uses and 2) numbers of workers associated with manufacturing
and downstream uses. The ITC needs this information to assess
occupational exposures.
4. Vanadium compounds. In its 51\st\ ITC Report, the ITC added 43
vanadium compounds to the Priority Testing List to obtain importation,
production, use, exposure, and health effects information to meet U.S.
Government data needs (Ref. 7). At the ITC's request, the EPA added the
43 vanadium compounds to the June 11, 2003 PAIR rule (Ref. 9). In its
54\th\ ITC Report, the ITC removed 25 vanadium compounds from the
Priority Testing List because information submitted in response to the
PAIR rule suggested low potential for occupational exposure (Ref. 10).
At this time, the ITC needs data on water and sediment
concentrations of vanadium species in fly ash ponds and related
impoundments (fluid-filled depressions) and the pH of these ponds and
impoundments. In addition, the ITC needs information on any wildlife
mortality events occurring near these impoundments. A recent study that
described the toxicity and hazard of vanadium to mallard ducks and
Canada geese was conducted because of wildlife mortalities that
occurred in a Delaware oil refinery fly ash pond contaminated with
vanadium compounds (Ref. 11).
In this 56\th\ ITC Report, the ITC is removing 6 vanadium compounds
from the Priority Testing List (Table 10 of this section).

The ITC is removing vanadium oxide (VO) (CAS No. 12035-98-2),
vanadium oxide (VO2) (CAS No. 12036-24-1), vanadium nitride (VN) (CAS
No. 24646-85-3) and vanadium, oxo[sulfato(2-)-.kappa.O]- (Vanadyl
sulfate) (CAS No. 27774-13-6) from the Priority Testing List because
information submitted in response to the PAIR rule suggested low
potential for occupational exposure. The ITC is removing vanadium
carbide (CAS No. 11130-21-5) and vanadium hydroxide oxide phosphate
(CAS No. 65232-89-5) from the Priority Testing List because neither is
likely to be a contaminant in fly ash ponds and related impoundments.
