### Background

The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 etseq.) authorizes the Administrator ofthe EPA to promulgate regulations under section 4(a) 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 orthe environment. Section 4(e) of TSCA established the ITC to recommend chemicals and chemical mixtures to the Administrator ofthe EPA for priority testing consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA section 4(e) PriorityTestingListat least every 6 months.

I. Background

The ITC was established by section 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 fortesting under section 4(a).... At least every six months

.... the Committee shallmake such revisions to the PriorityTestingListas it determines to be
necessary and transmit them to the Administrator togetherwith the Committee's

reasons for the revisions" (Public Law 94- 469, 90 Stat. 2003 etseq., 15 U.S.C. 2601 et seq.). Since its creation in 1976, the ITC has submitted 51 semi-annual (May and November) reports to the EPA Administrator transmitting the PriorityTestingListand its revisions. ITC reports are available from the ITC's web site (http://www.epa.govlopptintrlitc) within a few days of submission to the Administrator and from http://www.epa.govlfedrgstr after publication in the Federal Register. The ITC
meets monthly and produces its revisions to the PriorityTestingListwith 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 thisreport.

II. TSCA Section 8 Reporting

A. TSCA Section 8ReportingRules

Following receipt ofthe ITC's report (and the revised Priority TestingList)by the EPA Administrator, theEPA's Office ofPollution Prevention and Toxics (OPPT) appends the chemicals added to thePriorityTestingList to 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 andimporters ofChemical Abstract Service (CAS)-numbered chemicals added to thePriorityTestingListto submit production and exposure reports (http:// www.epa.gov/opptintr/chemtest/ pairform.pdfl. The HaSDR rule requires producers, importers, and processors ofall chemicals (including those with no CAS numbers) added to thePriorityTestingList 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 bereceived by the EPA within 90 days ofthe reporting rules Federal Register publication date. The reporting rules are automatically promulgated by OPPT unless otherwise requested by the ITC.
B.ITC's UseofTSCA Section 8and Other Information

The ITC reviews the TSCA section 8(a) PAIR rule reports, TSCA section 8(d)HaSDR rule studies and other information that becomes available after the ITC adds chemicals to the Priority TestingList. Other information includes TSCA section 4(a) studies, TSCA section 8(c) submissions, TSCA section 8(e) "substantial risk" notices, "For YourInformation" (FYI) submissions, unpublished data submitted to and from U.S. Government organizations represented on the ITC, published papers, as well as use, exposure, effects, and persistence data that 

### 43610

### Federal Register/Vol. 68, No. 141/Wednesday, July 23, 2003/Notices

are voluntarily submitted to the ITCby manufacturers, importers, processors, and

users ofchemicals recommended by the ITC. The ITCreviews this information and determines ifdata needs should berevised, ifchemicals should be removed from the PriorityTestingListorifrecommendations shouldbe changed to designations. To avoid duplicate reporting, the ITC carefully coordinates its information solicitations and reporting requirements with other national and international testing programs, e.g., the National Toxicology Program (NTP) (http:ll ntp-server.niehs.nih.gov/),the Organization for Economic Cooperation and Development (OECD) Screening Information Data Set (SIDS) Program (http://www.oecd.org)and EPA's High Production Volume (HPV) Challenge Program (http://www.epa.govl opptintrchemrtk volchall.htm).

C.PreviousandNew Requests toAdd Chemicalsto TSCA Section 8(a)PAIRRules

The following chemicals will be added to

a TSCA section 8(a) PAIR rule: Benzenamine, 3-chloro-2,6-dinitro-N,N-dipropyl-4- (trifluoromethyl)- (CAS No. 29091-20-1) (Ref. 2); stannane, dimethylbis[(1- oxoneodecyl)oxy]- (CAS No. 68928-76-7), benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5) and 1-triazene, 1,3- diphenyl- (CAS No.136-35-6) (Ref. 3); and 43 vanadium compounds (Ref. 4). At thistime, there are no new requests to add chemicals
to the TSCA section 8(a) PAIR rule.

D.PreviousandNew RequeststoAdd Chemicalsto TSCA Section 8(d)HaSDR Rules

The ITChas requested inprevious reports to the EPA Adminstrator that the following chemicals be added to TSCA section 8(d) HaSDR rules: H-1,2,4-triazole-3-thione, 5- amino-1,2-dihydro- (3-amino-5-mercapto1,2,4-triazole) (CAS No. 16691-43-3) and imidazol[4,5-d]imidazole-2,5(IH,3H)-dione, tetrahydro- (glycoluril) (CAS No. 496-46-8) (Ref. 5); 9 indium compounds (Ref. 6); benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)- (CAS No. 29091-20-1) (Ref. 2); and stannane, dimethylbis[(1-oxoneodecyl)oxy]- (CAS No. 68928-76-7), benzene, 1,3,5-tribromo-2-(2- propenyloxy)- (CAS No. 3278-89-5) and Itriazene, 1,3-diphenyl- (CAS No.136-35-6) (Ref. 3). At this time, the ITCis requesting that theEPA not add vanadium compounds
to the TSCA section 8(d) HaSDR rule to allow producers and importers of vanadium compounds an opportunity to voluntarily provide the information requested in section IV.A.3. of the 5111ITC Report (Ref. 4).

For 3H-1,2,4-triazole-3-thione, 5-amino1,2-dihydro- (3-amino-5-mercapto-1,2,4- triazole) and imidazo[4,5-d]imidazole-2,5- (1H,3H)-dione, tetrahydro- (glycoluril), the ITCrequests that the TSCA section 8(d) HaSDR rule require the submission of pharmacokinetics, subchronic toxicity, immunotoxicity, genotoxicity, carcinogenicity, reproductive effects and developmental toxicity, and ecological effects studies. Only studies for which 3-amino-5- mercapto-1,2,4-triazole or glycoluril is > 90% ofthe test substance by weight should be submitted. For the 9 indium compounds remaining on the PriorityTestingList,the ITC requests that the TSCA section 8(d) HaSDR rule require the submission ofpharmacokinetics, genotoxicity, subchronic and chronic toxicity, reproductive effects and developmental toxicity studies. Only studies where indium compounds are> Y90% ofthe
test substance by weight should be submitted. Indium tin oxide was inadvertently listed inthe 5 1st ITC Report with CAS No. 17906-67-7. The correct CAS number for indium tin oxide is 50926-11-9

as listed inthe 4 7th ITC Report. Indium tin oxide with CAS No. 50926-11-9 will be added to the TSCA section 8(d) HaSDR rule.

For benzenamine, 3-chloro-2,6-dinitroN,N-dipropyl-4- (trifluoromethyl)-, the ITC requests that the TSCA section 8(d)HaSDR rule require the submission of biodegradation, bioconcentration, pharmacokinetics, subchronic toxicity, mutagenicity, reproductive effects and developmental toxicity, carcinogenicity, and ecological effects studies. Only studies where benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4- (trifluoromethyl)- is >90% of the
test substance by weight should be submitted.

For stannane, dimethylbis[(1- oxoneodecyl)oxy]-, the ITCrequests that the TSCA section 8(d) HaSDR rule require the submission ofhydrolysis, biodegradation, bioconcentration, pharmacokinetics, subchronic toxicity, mutagenicity, neurotoxicity, reproductive effects and developmental toxicity, carcinogenicity, and ecological effects studies. Only studies where stannane, dimethylbis[(1-oxoneodecyl)oxy]- is > 90% ofthe test substance by weight should be submitted.

For benzene, 1,3,5-tribromo-2-(2- propenyloxy)-, the ITCrequests that the TSCA section 8(d) HaSDR rule require the submission ofbiodegradation, bioconcentration, pharmacokinetics, subchronic toxicity, neurotoxicity, reproductive effects and developmental toxicity, carcinogenicity, and ecological effects studies. Only studies where benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is > 90% of the test substance by weight should be submitted.

For 1-triazene, 1,3-diphenyl-, the ITC requests that the TSCA section 8(d)HaSDR rule require the submission of pharmacokinetics, genotoxicity, subchronic and chronic toxicity, reproductive effects and developmental toxicity studies. Only studies where 1-triazene, 1,3-diphenyl- is > 90% of the test substance by weight should be submitted.

At this time, there are no new requests to add chemicals to the TSCA Section 8(a) HaSDR Rule.

III. ITC's Activities During this Reporting Period (November 2002 to May 2003): Voluntary Information Submissions Innovative Online Network (VISION)

In its 51st ITC Report, the ITC announced that it would consider revising its voluntary information submission procedures to encourage greater and more efficient use of its VISION. The ITChas reviewed its voluntary information submission procedures and considered industry
comments discussed inthe 5 1stITC Report. At this time, the ITC is revising the VISION

as outlined inthis unit. The revised VISION will be accessible on the ITCweb site following submission ofthis 5 2 nd ITCReport
to the EPA Administrator.

1.The ITCwill continue to acknowledge trade organizations and companies that voluntarily submit information in response to

an ITC solicitation. During this reporting period, the ITCacknowledges the voluntary submissions ofinformation from the Color Pigments Manufacturers Association on DEBITS chemicals and vanadium compounds and from the Indium Corporation ofAmerica on indium compounds as requested in previous ITC reports.

2. The ITC has requested that the EPA include ITC's solicitations for voluntary information submissions in the summary and body ofthe preambles that are prepared for publication ofthe ITC's reports in the Federal Register. This change should allow companies to readily determine ifthe ITCis soliciting voluntary information for chemicals they produce orimport.

3. The ITCwill notify major chemical trade associations by e-mail that new ITCreports have been posted to the ITC's web site (http:/ /www.epa.govlopptintrlitc/).The e-mails will include a summary ofthereport and
announcements ofnew information solicitations. This change should increase

awareness ofthe ITCinformation solicitations and encourage voluntary submission ofdata.

4. The voluntary information submissions should be submitted within 90 days ofthe date the ITCreport is published inthe Federal Register. Failure to voluntarily submit information in a timely manner may lead ITC to request that the EPA promulgate the appropriate TSCA section 8(a) and 8(d) reporting rules in a subsequent report to the EPA Administrator.

5. The ITCwill accept hard copy or electronic voluntary information submissions. All submissions should be titled as ITC-FYI and should bear the document control number or document ID number ofthe ITC report for which the submission is being provided, e.g., the docket ID number forthe 5 0 th ITC Report is OPPT2002-0026. Confidential Business Information (CBI) must be submitted as hard copies. Both sanitized (no CBI) and unsanitized (CBI) versions must be provided.

6. Information submitted voluntarily will
not have to be re-submitted under a TSCA section 8(d) rule.

7. Voluntary information may be submitted by mail, inperson orby courier, or electronically.
