Fifty-Fifth 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 Fifty-Fifth Report to the Administrator
of EPA on December 8, 2004. In the 55\th\ ITC Report, which is included
with this notice, the ITC is revising the Priority Testing List by
adding a category of high production volume (HPV) orphan chemicals and
requesting that EPA add these chemicals to the TSCA section 8(a)
Preliminary Assessment Information Reporting (PAIR) rule and the TSCA
section 8(d) Health and Safety Data Reporting (HaSDR) rule. The ITC is
also removing the following chemicals from the Priority Testing List:
3-amino-5-mercapto-1,2,4-triazole; glycoluril; benzenamine, 3-chloro-
2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)-; stannane,
dimethylbis[(1-oxoneodecyl)oxy]-; benzene, 1,3,5-tribromo-2-(2-
propenyloxy)-; and1-triazene, 1,3-diphenyl-.]. Since the 55\th\ Report
was ITC transmitted to the Administrator and made publicly available on
http://www.epa.gov/opptintr/itc/, five HPV orphan chemicals have been
removed from the Priority Testing List because chemical manufacturers
committed to prepare robust summaries for these chemicals in response
to the HPV Challenge Program. The ITC encourages other manufacturers to
make similar commitments so their chemicals can be removed from the
Priority Testing List and potentially avoid being added to PAIR and
HaSDR rules.

DATES: Comments, identified by docket identification (ID) number OPPT-
2004-0130, must be received on or before March 14, 2005.

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. 260l et seq.)
authorizes the Administrator of the EPA to promulgate regulations under
section 4(a) of TSCA 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 the 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.

A. The ITC's 55\th\ Report

The 55\th\ ITC Report was transmitted to EPA's Administrator on
December 8,

[[Page 7366]]

2004, and is included in this notice. In the 55\th\ ITC Report, the ITC
is revising the Priority Testing List by adding a category of HPV
orphan chemicals and requesting that EPA add these chemicals to the
TSCA section 8(a) PAIR rule and the TSCA section 8(d) HaSDR rule. The
ITC is also removing the following chemicals from the Priority Testing
List: 3-amino-5-mercapto-1,2,4-triazole; glycoluril; benzenamine, 3-
chloro-2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)-; stannane,
dimethylbis[(1-oxoneodecyl)oxy]-; benzene, 1,3,5-tribromo-2-(2-
propenyloxy)-; and 1-triazene, 1,3-diphenyl-.

B. Status of the Priority Testing List

The current TSCA 4(e) Priority Testing List as of December 2004 can
be found in Table 1 of the 55\th\ ITC Report, which is included in this
notice.

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 (http://www.epa.gov/
opptintr/itc/) within a few days of submission to the Administrator
and from the EPA's web site http://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 and 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)
Preliminary Assessment Information Reporting (PAIR) and TSCA section
8(d) Health and Safety Data Reporting (HaSDR) rules. The PAIR rule
requires producers and importers of chemicals added to the Priority
Testing List to submit production and exposure reports (http://
www.epa.gov/opptintr/chemtest/pairform.pdf/). The HaSDR rule
requires producers, importers and processors of all 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 must be received by the
EPA within 90 days of the reporting rules Federal Register
publication date.

[[Page 7367]]

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 previous ITC Reports (http://www.epa.gov/opptintr/itc/
rptmain.htm/).

C. Previous Requests to Add Chemicals to the TSCA Section 8(a) PAIR
Rule

In its 53\rd\ Report, the ITC requested that EPA add 3
pyridinamines and 20 tungsten compounds to the TSCA section 8(a)
PAIR rule (Ref. 2). On December 7, 2004, EPA issued a final rule,
pursuant to TSCA section 8(a) requiring producers and importers of
these 23 chemicals to report production, importation, and exposure
data to EPA (Ref. 3).

D. New Requests to Add Chemicals to the TSCA Section 8(a) PAIR and
8(d) HaSDR Rules

In this report, the ITC is requesting that EPA add the HPV
orphan chemicals listed in Appendix A to the TSCA section 8(a) PAIR
and 8(d) HaSDR rules. The ITC is requesting that these HPV orphan
chemicals be added to the TSCA section 8(a) PAIR and 8(d) HaSDR
rules because no voluntary studies have been submitted to the EPA in
response to the HPV Challenge Program (http://www.epa.gov/opptintr/
chemrtk/volchall.htm/).

III. ITC's Activities During this Reporting Period (May to November
2004)

During this reporting period, the ITC reviewed the reports
submitted in response to the June 11, 2003, PAIR rule (Ref. 4) and
the May 4, 2004, TSCA section 8(d) HaSDR rule (Ref. 5). The ITC is
continuing to review these reports.
The ITC also met with EPA to discuss procedures for making data
publicly available on HPV orphan chemicals (HPV chemicals for which
no sponsors have volunteered to develop and submit robust summaries
to the EPA). The ITC's discussions with EPA are described in section
IV. of this report.
As noted in the 51\st\ and 54\th\ ITC Reports (Refs. 6 and 7),
the ITC continues to request the following information on vanadium
compounds:
1. 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.
2. Estimates of the number of humans and concentrations of
vanadium chemicals to which humans may be exposed in each relevant
manufacturing or processing scenario.
3. 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.
In addition, the ITC is concerned that some of these compounds
may be released into fly ash ponds at power plants, petroleum and
chemical refineries, and mining sites and could be toxic to avian
and wildlife species as exemplified by a recent report of dead and
dying Canada geese at a petroleum refinery fly ash pond in Delaware.
In these geese, the vanadium concentrations in pooled liver and
kidney samples were 57 and 226 [mu]g/gram (g) dry weight,
respectively. Background concentrations of vanadium in various
tissues of higher vertebrates, including waterfowl, rarely exceed 1
[mu]g/g dry weight. Limited data are available on vanadium toxicity
in birds and other wildlife making it difficult to interpret the
findings from the geese die-off.
The ITC knows that vanadium is released into impoundments at 172
facilities in 33 states and that the TRI does not have vanadium
concentrations for these impoundments. The ITC is soliciting data on
concentrations and species of vanadium compounds in impoundments at
power plants, petroleum and chemical refineries, and mining sites
and information on the use, release, and presence of vanadium
compounds at these facilities. The ITC needs these data and
information to determine if avian wildlife in the vicinity of the
172 facilities are at risk from exposure to vanadium compounds. If
you have any questions regarding the applicability of this action to
a particular entity, consult the technical person listed under FOR
FURTHER INFORMATION CONTACT.

IV. Revisions to the TSCA Section 4(e) Priority Testing List

A. Chemicals Added to the Priority Testing List: HPV Orphan
Chemicals

1. Recommendation. EPA requests that the ITC add the category
HPV orphan chemicals listed in Appendix A of this report to the
Priority Testing List to obtain importation, production, use, and
exposure information as well as unpublished physical/chemical
property, environmental fate, health effects, and ecological effects
information to meet U.S. Government data needs.
2. Rationale for recommendation. While the success of the HPV
Challenge Program has been significant, hundreds of chemicals that
were eligible for sponsorship in the Program continue to remain
unsponsored. These chemicals are referred to as ``orphans.'' There
is little or no publicly available information regarding the
potential hazards associated with these chemicals. EPA remains
committed to obtain basic screening level hazard information on
these chemicals through voluntary sponsorship, as well as through
TSCA information gathering and test rules, as necessary.
3. Supporting information. In developing the list of HPV orphan
chemicals presented in Appendix A of this report, EPA considered all
of the HPV orphan chemicals and then removed selected HPV orphan
chemicals. The HPV orphan chemicals presented in Appendix A of this
report do not include those HPV orphan chemicals that:
a. Had 2002 Inventory Update rule reported production/
importation volumes > one million pounds (http://www.epa.gov/oppt/
iur/iur02/index.htm/ ) and were proposed for testing in the first
HPV test rule (Ref. 8).
b. Meet the ``No Longer HPV'' criteria (i.e., chemicals with
production/importation volumes < 1 million pounds based on 1998 and
2002 Inventory Update Rule data (http://www.epa.gov/oppt/iur/iur02/
index.htm/)).
c. Are being considered for a second HPV TSCA section 4 test
rule because they may meet the TSCA section 4(a)(1)(B) statutory
requirements.
At EPA's request, the ITC encourages manufacturers of these
chemicals to visit the EPA's HPV Challenge Program web site (http://
www.epa.gov/opptintr/chemrtk/volchall.htm/) and to make a commitment
to sponsor these chemicals at the present time, before regulatory
actions are initiated. EPA will initiate development of TSCA section
8(a) PAIR and 8(d) HaSDR rules soon after these chemicals are added
to the Priority Testing List and the ITC's 55\th\ Report is
published in the Federal Register. Also at EPA's request, the ITC
encourages the submission of robust summaries of studies submitted
under the TSCA section 8(d) HaSDR rule to facilitate EPA's review of
the unpublished TSCA section 8(d) studies (see USEPA. 1999. Draft
Guidance on Developing Robust Summaries. October 22, 1999 (http://
www.epa.gov/chemrtk/robsumgd.htm/)). While some of the HPV orphan
chemicals have been previously added to the TSCA section 8(d) HaSDR
rule, all of the sunset dates for these chemicals have expired (see
Appendix A of this report), thus new and so far unreported studies
would need to be submitted. Information about the environmental fate
and potential hazards associated with these chemicals when combined
with information about exposure and uses will allow the EPA and
others to evaluate and prioritize potential health and environmental
effects and determine the need for test rules under TSCA section
4(a). If you have any questions regarding the applicability of this
action to a particular entity, consult the technical person listed
under FOR FURTHER INFORMATION CONTACT.
4. Information needs. For each individual substance listed in
Appendix A of this report, EPA needs the following information to
assess the extent and degree of exposure and potential hazard
associated with these substances:
a. Production, importation, processing, use and associated
exposure information that is captured under the TSCA section 8(a)
PAIR form.
b. Unpublished studies of:
i. Physical/chemical properties and environmental fate for the
properties listed in 40 CFR 716.50 as well as melting point and
boiling point.
ii. Health effects including pharmacokinetics, genotoxicity,
acute toxicity, subacute toxicity, subchronic toxicity, chronic
toxicity, reproductive toxicity, developmental toxicity,
immunotoxicity, neurotoxicity, and oncogenicity/carcinogenicity.
iii. Ecological effects including acute and chronic toxicity
studies of aquatic and terrestrial vertebrates and invertebrates and
aquatic plants.
c. Only studies where the recommended HPV orphan chemical is >=
90% of the test substance by weight should be submitted. In

[[Page 7368]]

addition, only studies that were conducted using TSCA, Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA), Organization
for Economic Cooperation and Development (OECD), or other
internationally accepted test guidelines or voluntary consensus
standards should be submitted. Studies performed where the
recommended HPV orphan chemical is < 90% of the test substance by
weight are not requested at this time.

B. Chemicals Removed From the Priority Testing List

1. 3-Amino-5-mercapto-1,2,4-triazole. 3-Amino-5-mercapto-1,2,4-
triazole (Chemical Abstracts Service Registry Number (CAS No.)
16691-43-3 ) was added to the Priority Testing List in the ITC's
42\nd\ Report to obtain annual production/importation volumes and
trends, use, exposure, and health effects data (Ref. 9). The
addition was based on concerns that 3-amino-5-mercapto-1,2,4-
triazole was structurally related to 3-amino-1,2,4-triazole
(Amitrol[reg]), a herbicide that affects thyroid hormone activity
(Ref. 10). In response to the ITC's request, the EPA added 3-amino-
5-mercapto-1,2,4-triazole to the July 24, 2000, PAIR rule (Ref. 11)
and the May 4, 2004 HaSDR rule (Ref. 5). Numerous studies were
submitted in response to the HaSDR rule. These studies are
summarized in this unit. 3-Amino-5-mercapto-1,2,4-triazole was
positive in the mouse bone marrow micronucleus test, clastogenic to
rat lymphocytes, but not mutagenic in the Ames assay using strains
TA98, 100, 1535, and 1537 or in the E. coli assay, using strain WP2
uvrA-. 3-Amino-5-mercapto-1,2,4-triazole was a mild eye and skin
irritant, but not a skin sensitizer. In a 4-week inhalation study
the no observed effect level of 3-amino-5-mercapto-1,2,4-triazole
was 20 milligram/meter cubed (mg/m\3\).
3-Amino-5-mercapto-1,2,4-triazole is being removed from the
Priority Testing List because information submitted in response to
the PAIR rule suggested that 3-amino-5-mercapto-1,2,4-triazole is an
on-site intermediate and the production/importation volumes were
lower than the 250,000 pounds of 3-amino-5-mercapto-1,2,4-triazole
imported into the United States in 1993 (Ref. 9).
2. Glycoluril. Glycoluril (CAS No. 496-46-8) was also added to
the Priority Testing List in the ITC's 42\nd\ Report to obtain
annual production/importation volumes and trends, use, exposure, and
health effects data. The addition was based on a potential for human
exposure and a suspicion of carcinogenicity (Ref. 9). In response to
the ITC's request, the EPA added glycoluril to the July 24, 2000
PAIR rule (Ref. 11) and the May 4, 2004 HaSDR rule (Ref. 5). No
studies were submitted in response to the HaSDR rule.
Glycoluril is being removed from the Priority Testing List
because information submitted in response to the PAIR rule suggested
that glycoluril is an on-site intermediate and the production/
importation volumes were less than the 10,000 to 1,000,000 pounds of
non-CBI annual production/importation volumes reported to the EPA in
1986, 1990, and 1994 (Ref. 9).
3. Benzenamine, 3-chloro-2,6-dinitro-N,N-dipropyl-4-
(trifluoromethyl)-. Benzenamine, 3-chloro-2,6-dinitro-N,N-dipropyl-
4-(trifluoromethyl)- (aka 3-Chlorotrifluralin (CAS No. 29091-20-1)
was added to the Priority Testing List in the ITC's 48\th\ Report to
obtain information on uses, exposures, environmental releases,
pharmacokinetics, subchronic toxicity, mutagenicity, reproductive
and developmental effects, carcinogenicity, and ecological effects
(Ref. 12). Benzenamine, 3-chloro-2,6-dinitro-N,N-dipropyl-4-
(trifluoromethyl)- was added to the Priority Testing List because it
has an estimated bioconcentration factor (BCF) of 7,700 and is a
chlorinated analog of trifluralin (CAS No. 1582-09-8), the herbicide
that causes adverse effects in experimental animals and is
considered to be a possible human carcinogen by the EPA (Ref. 12).
In response to the ITC's request, the EPA added benzenamine, 3-
chloro-2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)- to the June 11,
2003 PAIR rule (Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR
rule (Ref. 5). No information was submitted in response to the PAIR
or HaSDR rules. The ITC is removing benzenamine, 3-chloro-2,6-
dinitro-N,N-dipropyl-4-(trifluoromethyl)- from the Priority Testing
List because the PAIR rule did not provide any additional exposure
information implying that benzenamine, 3-chloro-2,6-dinitro-N,N-
dipropyl-4-(trifluoromethyl)- is not produced at greater than 1,000
pounds per site.
4. Stannane, dimethylbis[(1-oxoneodecyl)oxy]-. Stannane,
dimethylbis[(1-oxoneodecyl)oxy]- (CAS No. 68928-76-7) was added to
the Priority Testing List in the ITC's 49\th\ Report to obtain use,
exposure, environmental fate, health effects, and ecological effects
data (Ref. 13). Stannane, dimethylbis[(1-oxoneodecyl)oxy]- was added
to the Priority Testing List because it has an estimated BCF of
8,600 and signs of toxicity, including neurotoxic effects that were
observed in a rat oral gavage study (Ref. 13).
In response to the ITC's request, the EPA added stannane,
dimethylbis[(1-oxoneodecyl)oxy]- to the June 11, 2003 PAIR rule
(Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5).
No information was submitted in response to the HaSDR rule. The ITC
is removing stannane, dimethylbis[(1-oxoneodecyl)oxy]- from the
Priority Testing List because the information submitted in response
to the PAIR rule suggested that the production/importation volumes
of stannane, dimethylbis[(1-oxoneodecyl)oxy]- were not greater than
the 10,000-500,000 pounds of non-CBI production/importation volumes
reported to the EPA in 2002 (http://www.epa.gov/oppt/iur/iur02/
index.htm/).
5. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)-. Benzene, 1,3,5-
tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5) was added to the
Priority Testing List in the ITC's 50\th\ Report to obtain use,
exposure, environmental fate, health effects, and ecological effects
data (Ref. 14). Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- was added
to the Priority Testing List because of an estimated BCF of 4,000
and potential for exposure from its use as a flame retardant for
expanded polystyrene insulation board (Ref. 14).
In response to the ITC's request, the EPA added benzene, 1,3,5-
tribromo-2-(2-propenyloxy)- to the June 11, 2003 PAIR rule (Ref. 4)
and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5).
Information submitted in response to the HaSDR rule indicated that
the concentrated chemical may be slightly irritating to the skin.
The ITC is removing benzene, 1,3,5-tribromo-2-(2-propenyloxy)- from
the Priority Testing List because the information submitted in
response to the PAIR rule suggested that the production/importation
volumes of benzene, 1,3,5-tribromo-2-(2-propenyloxy)- were not
greater than 10,000-500,000 pounds of non-CBI production/importation
volumes reported to the EPA in 2002 (http://www.epa.gov/oppt/iur/
iur02/index.htm/).
6. 1-Triazene, 1,3-diphenyl-. 1-Triazene, 1,3-diphenyl- (aka
diazoaminobenzene (CAS No. 136-35-6) was added to the Priority
Testing List in the ITC's 50\th\ Report to obtain annual production/
importation volumes and trends, use, exposure, and health effects
data (Ref. 14). 1-Triazene, 1,3-diphenyl- was added to the Priority
Testing List because it is a predicted carcinogen based on its
metabolism and similarity in toxic effects to benzene and aniline
(Ref. 14).
In response to the ITC's request, the EPA added 1-triazene, 1,3-
diphenyl- to the June 11, 2003 PAIR rule (Ref. 4) and the May 4,
2004 TSCA section 8(d) HaSDR rule (Ref. 5). No information was
submitted in response to the PAIR or HaSDR rules. The ITC is
removing 1-triazene, 1,3-diphenyl- from the Priority Testing List
because the PAIR rule did not provide any additional exposure
information implying that 1-triazene, 1,3-diphenyl- is not produced
at greater than 1,000 pounds per site.
