[OPPTS-41040; FRL-4750-9]
Thirty-Third Report of the TSCA Interagency Testing Committee to
the Administrator; Receipt of Report and Request for Comments
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The TSCA Interagency Testing Committee (ITC), established
under section 4(e) of the Toxic Substances Control Act (TSCA),
transmitted its Thirty-Third Report to the Administrator of EPA on
November 29, 1993. As noted in this Report, which is included with this
notice, the ITC revised the Priority Testing List by removing 2
chemicals and 4 chemical groups from the List for priority
consideration by the EPA Administrator for promulgation of test rules
under section 4(a) of the Act. The chemicals being removed are 2,4-
dinitrophenol and 3,4-dimethylphenol. The groups being removed are
imidazolium and ethoxylated quaternary ammonium compounds (8
chemicals), brominated flame retardants (23 chemicals), and alkyl
phosphates (20 chemicals). The Report indicates that removal of these
chemicals and chemical groups from the List should be interpreted only
as a reordering of priorities and not a statement that the testing
recommended earlier has been completed or is not needed. Prior to
removing chemicals from the List, the ITC reviewed about 80 TSCA
section 8(a) reports and 850 TSCA section 8(d) studies. The ITC is
sharing summaries of these reviews with appropriate EPA programs
offices and other concerned Federal agencies to assist them in risk
assessment and management activities.
There are no additions to the Priority Testing List.
EPA invites interested persons to submit written comments on the
Report.
DATES: Written comments on the Thirty-third ITC Report should be
submitted by February 25, 1994.
ADDRESSES: Send six copies of written submissions to: TSCA Docket

SUPPLEMENTARY INFORMATION: EPA has received the TSCA Interagency
Testing Committee's Thirty-Third Report to the Administrator.
I. Background
TSCA (Pub. L. 94-469, 90 Stat. 2003 et seq; 15 U.S.C. 260l et seq.)
authorizes the Administrator of EPA to promulgate regulations under
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 Interagency Testing Committee to
recommend chemicals and chemical groups to the Administrator of EPA for
priority testing consideration. Section 4(e) directs the ITC to revise
the TSCA section 4(e) Priority Testing List at least every 6 months.
The most recent revisions to this List are included in the ITC's
Thirty-Third Report. The Report was received by the Administrator on
November 29, 1993, and is included in this Notice. The Report removes
two chemicals and four chemical groups from the TSCA section 4(e)
Priority Testing List.
These chemical substances and chemical groups were previously added
to the TSCA section 8(d) Health and Safety Data Reporting Rule (40 CFR
part 716) in response to the ITC testing recommendations. These
substances will be considered for removal from the 8(d) rule during the
next 8(d) rule ``biennial review,'' scheduled to occur during 1995. See
40 CFR 716.65(b).
II. Written and Oral Comments
EPA invites interested persons to submit detailed comments on the
ITC's Report. All submissions should bear the identifying docket number
(OPPT-41040).
III. Status of List
The ITC's Thirty-Third Report notes the removal of 2 chemicals and
4 chemical groups from the Priority Testing List. The current TSCA
section 4(e) Priority Testing List contains 16 chemicals and 12
chemical groups, with two chemical groups and 7 chemicals designated
for testing.
Authority: 15 U.S.C. 2603.

Thirty-Third Report Of The TSCA Interagency Testing Committee To
The Administrator, U.S. Environmental Protection Agency
Summary: This is the 33rd Report of the TSCA Interagency Testing
Committee (ITC) to the Administrator of the U.S. Environmental
Protection Agency (EPA). The ITC is revising its Priority Testing List
by removing two chemicals and four chemical groups. The chemicals being
removed are 2,4-dinitrophenol and 3,4-dimethylphenol. The groups being
removed are imidazolium and ethoxylated quaternary ammonium compounds,
brominated flame retardants, and alkyl phosphates. These revisions are
based on current priorities of ITC Member agencies and a review of
production and exposure reports and health and safety studies submitted
by manufacturers, processors, and distributors for these chemicals and
chemical groups.
I. Background
The TSCA Interagency Testing Committee (ITC) was established by
subsection 4(e) of the Toxic Substances Control Act (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 a rule for testing under
subsection 4(a)... At least every 6 months..., the Committee shall make
such revisions in the List as it determines to be necessary and to
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.). Since its creation in 1976, the ITC has
submitted 32 semi-annual Reports to the EPA Administrator transmitting
the Priority Testing List and its revisions. These Reports have been
published in the Federal Register and are available from the ITC. The
ITC meets monthly and produces its revisions with the help of staff and
technical contract support provided by EPA. ITC membership and support
personnel are listed at the end of this Report.
Following receipt of the ITC's Report, the EPA's Office of
Pollution Prevention and Toxics may promulgate TSCA subsection 8(a) and
8(d) rules that require manufacturers, processors, and/or distributors
of chemicals on the Priority Testing List to submit production and
exposure data (8a), and health and safety studies (8d), within 2 months
of the rules' effective dates. The submissions are indexed and
maintained by EPA. The ITC reviews the 8(a) and 8(d) information and
other available data on chemicals and chemical groups to determine if
revisions to the Priority Testing List are necessary. Revisions include
changing a recommendation to a designation for action by the
Administrator within 12 months, modifying the recommended testing, or
removing the chemical or group from the List.
The substituted phenols were recommended for testing in 1990 and
the chemical groups were added to the Priority Testing List following
the Committee's 1986 sixth scoring exercise (Ref. 1). The sixth scoring
exercise was a systematic, computerized chemical selection procedure
for identifying chemicals of concern, further defined by chemical
substructural features (Ref. 5).
II. Revisions to the TSCA Section 4(e) Priority Testing List
The ITC removes the following chemicals and chemical groups from
the TSCA Section 4(e) Priority Testing List (Table 1).

a Brominated flame retardants were recommended as 2 groups in the 25th
Report (7 chemicals) and 26th Report (16 chemicals).
III. Rationale for the revisions
A. ITC's Activities During this Reporting Period
During the 6 months covered by this Report, May through October
1993, the ITC reviewed the 8(a) and 8(d) submissions and other
available data for chemicals and chemical groups recommended in its
22nd, 23rd, 25th, 26th, and 27th Reports. The Federal Register
citations for the 8(a) and 8(d) rules and the number of 8(d) studies
reviewed by the ITC for each chemical or chemical group are summarized
in the following Table 2. Approximately 80 TSCA 8(a) reports were
reviewed by the ITC; but the exact number is not reported for each
chemical or group to protect TSCA Confidential Business Information.

------------------------------------------------------------------------
a Brominated flame retardants were recommended as two groups in the 25th
and 26th Reports.
Also during this reporting period, the ITC reevaluated the priority
for testing these chemicals and chemical groups at the urging of EPA in
view of current EPA and Member agency priorities. The ITC has
determined that the chemicals and groups listed in its recent Reports
are of higher priority than some of the chemicals recommended in
earlier Reports and is reordering priorities to reflect this
determination. For the chemicals removed from the List, the ITC will
forward to the appropriate EPA program office(s), or other Federal
Government organizations, its review of 8(d) studies and other relevant
information to assist them in risk assessment and management
activities, regulatory actions, or for renomination to the TSCA section
4(e) Priority Testing List. The ITC will also include these TSCA 8(d)
summary reports in the public docket supporting this ITC Report. In
those cases in which the testing recommendations originally made by the
ITC have not been met, the ITC encourages manufacturers, processors,
and distributors of the removed chemicals to conduct voluntary testing
programs to provide the recommended test data.
B. Specific Rationales
1. 2,4-Dinitrophenol and 3,4-Dimethylphenol. These substituted
phenols were nominated to the ITC by EPA in June 1990 and added to the
Priority Testing List in November 1990. Chemical fate, health effects
and ecological effects testing were recommended as described in the
ITC's 27th Report to the EPA Administrator (56 FR 9534, March 6, 1991).
The rationale for recommending health effects testing of these
chemicals was to provide needed test data to increase the confidence
for EPA's Reference Concentrations (RfC) and Reference Doses (RfD). The
rationale for recommending chemical fate and ecological effects testing
was to provide data that could be used by EPA to assess ecological
risk.
Based on a review of 8(d) studies for these chemicals, the
recommended testing has not been conducted. However, the ITC decided
that these testing recommendations are currently of relatively lower
priority than others and removes these chemicals from the Priority
Testing List.
2. Imidazolium and ethoxylated quaternary ammonium compounds.
Imidazolium and ethoxylated quaternary ammonium compounds were
recommended for health effects, chemical fate and ecological effects
testing in the ITC's 22nd Report (53 FR 18196, May 20, 1988). The major
concerns were for long-term dermal consumer exposure, toxicity to
aquatic organisms and persistence in aquatic environments. For this
33rd Report, the ITC reviewed toxicity and exposure data summarized in
the 22nd Report, data submitted to EPA under TSCA sections 8(a) and
8(d) and reports from the Chemical Specialties Manufacturing
Association (CSMA) describing structures, testing and uses of
imidazolium and ethoxylated quaternary ammonium compounds in fabric
softeners, and studies on health effects, chemical fate and ecological
effects (Ref. 2, 3, and 4). After reviewing all these studies, the ITC
concludes that there is no additional suspicion of health hazard or
human exposure for these quaternary ammonium compounds and that
potential effects to aquatic organisms are likely to be mitigated by
the binding of these quaternary ammonium compounds to particulate
organic carbon. For these reasons, the ITC believes that the previously
recommended testing is not of sufficiently high priority at this time.
The imidazolium and ethoxylated quaternary ammonium compounds are,
therefore, being removed from the Priority Testing List. If, in the
future, sufficient concerns arise regarding the health or ecological
effects of these compounds, individual members of this group may be
designated for testing.
3. Brominated Flame Retardants. Two groups of brominated flame
retardants were added to the Priority Testing List in November 1989 and
May 1990. Chronic health and ecological effects and physical/chemical
properties and persistence testing were recommended for a group of
seven brominated flame retardants in the ITC's 25th Report (54 FR
51114, December 12, 1989). Physical/chemical properties and persistence
testing were recommended for a group of 16 brominated flame retardants
in the ITC's 26th Report (55 FR 23050, June 5, 1990). Based on review
of TSCA section 8(a) and 8(d) submissions, available production data
and EPA's testing priorities, the ITC removes the brominated flame
retardants from the Priority Testing List. The most recent, available
production data reviewed by the ITC were submitted to EPA in response
to the 1990 TSCA Inventory Update Rule (55 FR 39586, September 27,
1990) and the 8(a) rules.
Fifteen of the brominated flame retardants are being removed from
the List because they are not known to be domestically produced or
imported in substantial quantities. These include 3 from the 25th
Report: ethylene bis(tetrabromophthalimide) (32588-76-4); ethylene
bis(5,6-dibromonorbornane-2,3-dicarboximide) (41291-34-3) and ethylene
bis(pentabromophenoxide) (61262-53-1) and 12 from the 26th Report:
3,4',5-tribromo- salicylanilide (87-10-5); 2,3,4,5,6-pentabromotoluene
(87-83-2); 1,2,3,4,5-pentabromo-6- chlorocyclohexane (87-84-3); 2,3-
dibromopropanol (96-13-9); 2,4-dibromophenol (615-58-7); ethoxylated
tetrabromobisphenol A (4162-45-2); tetrabromobisphenol A bis(allyl
ether) (25327-89-3); tetrabromodichlorocyclohexane (30554-72-4);
tribromotrichlorocyclohexane (30554-73-5); tribromoneopentyl alcohol
(36483-57-5); tetrabromobisphenol A diacrylate (55205-38-4) and
C10-18 bromochloroalkanes (68955-41-9).
Tribrominated polystyrene (57137-10-7) from the 25th Report; 2,4-
(or 2,6)- dibromophenol homopolymer (69882-11-7); and brominated
polystyrene (88497-56-7) from the 26th Report are being removed from
the List because they are polymers with a lower probability of
absorption into biological tissues than nonpolymeric organic chemicals.
Dibromoneopentyl glycol (3296-90-0) from the 25th Report as well as
bromochloromethane (74-97-5) and vinyl bromide (593-60-2) from the 26th
Report are being removed from the List because their health effects are
reasonably well characterized and their occupational and environmental
exposures can be estimated.
2,4,6-Tribromophenol (118-79-6) and tetrabromophthalic anhydride
(632-79-1) from the 25th Report are being removed from the List at this
time to give adequate priority to recently identified testing needs for
other chemicals.
The ITC has prepared a report summarizing its review of the TSCA
8(d) studies for transmittal to the EPA's Existing Chemical Program and
other appropriate Federal Government organizations for possible risk
assessment and management activities, regulatory actions, or for
renomination to the TSCA section 4(e) Priority Testing List. This TSCA
8(d) summary report is included in the public docket supporting this
ITC Report.
4. Alkyl phosphates. Twenty alkyl phosphates were added to the
Priority Testing List in May 1990. Physical/chemical properties and
persistence testing were recommended in the ITC's 26th Report to the
Administrator (55 FR 23050, June 5, 1990).
The following 13 alkyl phosphates are being removed from the
Priority Testing List because they are not known to be domestically
produced or imported in substantial quantities: dibutyl phosphate (107-
66-4), triisobutyl phosphate (126-71-6), monomethyl phosphate (812-00-
0), mono(2-ethylhexyl) phosphate (1070-03-7), monobutyl phosphate
(1623-15-0), mono(isopropyl) phosphate (1623-24-1), monooctadecyl
phosphate (2958-09-0), monohexyl phosphate (3900-04-7), monooctyl
phosphate (3991-73-9), di-n-dodecyl phosphate (7057-92-3), 2-(2-
butoxy)ethanol phosphate (7332-46-9), dodecyl phosphate (12751-23-4)
and diisooctyl phosphate (27215-10-7).
Testing to provide physical/chemical properties and persistence
data for tributyl phosphate (126-73-8) is being conducted under TSCA
section 4 (54 FR, 33400, August 14, 1989). The remaining 6 alkyl
phosphates have substantial production volumes: triethyl phosphate (78-
40-0), tris(2-ethylhexyl) phosphate (78-42-2), tris(2-butoxyethyl)
phosphate (78-51-3), di(2-ethylhexyl) phosphate (298-07-7), ethyl
dichlorophosphate (1498-51-7) and 2-ethylhexyl phosphate (12645-31-7).
The ITC is removing them from the Priority Testing List because they
are not of sufficiently high priority at this time.
Dibutyl phosphate, which the ITC is removing from the Priority
Testing List because it is not substantially produced in the U.S., is
currently being tested as part of the Organisation for Economic
Cooperation and Development (OECD) Screening Information Data Set
(SIDS) program. The six ``substantially-produced'' alkyl phosphates
being removed from the List at this time are on OECD's High Production
Volume list of chemicals and may be subject to SIDS testing in the
future. Therefore, the ITC has forwarded a report summarizing its
information on the alkyl phosphates to the U.S. representative to the
OECD SIDS program. The ITC has prepared a report summarizing its review
of the TSCA 8(d) studies to send to the EPA's Existing Chemical Program
and other appropriate Federal Government organizations for possible
risk assessment and risk management activities, regulatory actions, or
for renomination to the TSCA section 4(e) Priority Testing List. This
TSCA 8(d) summary report is included in the public docket supporting
this ITC Report.
