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 mixtures in order to develop data relevant to determining the risks that such chemicals and chemical mixtures may present to health or the environment. Section 4( e) of TSCA established the ITC to recommend chemicals and chemical mixtures to the Administrator of the EPA for 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 51th ITC Report The 51th ITC Report was transmitted to the EPA's Administrator on November 26, 2002, and is included in this notice. In the 51st ITC Report, the ITC: 1.

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 a rule 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.). Since its creation in 1976, the ITC has submitted 50 semi annual ( May and November) Reports to the USEPA Administrator transmitting the Priority Testing List and its revisions. 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 http:// www. epa. gov/ fedrgstr after publication in the Federal Register. The ITC meets monthly and 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 USEPA. 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 USEPA Administrator, the USEPA's Office of Pollution Prevention and Toxics ( OPPT) appends the chemicals added to the Priority Testing List to TSCA section 8( a) PAIR and TSCA section 8( d) HaSDR rules. The PAIR rule requires producers and importers of Chemical Abstract Service ( CAS) numbered 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 ( including those with no CAS numbers) 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 USEPA within 90 days of the reporting rules Federal Register publication date. The reporting rules are automatically promulgated by OPPT unless otherwise requested by the ITC.

B. ITC's Use of TSCA Section 8 and 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 Testing List. Other information includes TSCA section 4( a) and 4( d) studies, TSCA section 8( c) submissions, TSCA section 8( e) `` substantial risk'' notices, `` For Your Information'' ( 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 are voluntarily submitted to the ITC by manufacturers, importers, processors, and users of chemicals recommended by the ITC. The ITC reviews this information and determines if data needs should be revised, if chemicals should be removed from the Priority Testing List or if recommendations should be 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:// ntpserver niehs. nih. gov/), the Organization for Economic Cooperation and Development ( OECD) Screening Information Data Set ( SIDS) Program ( http:// www. oecd. org), and the USEPA's High Production Volume ( HPV) Challenge Program ( http:// www. epa. gov/ opptintr/ chemrtk/ volchall. htm). C. Previous and New Requests to Add Chemicals to TSCA Section 8( a) PAIR Rules The ITC has requested in previous reports that USEPA add the following chemicals to the TSCA section 8( a) PAIR rules: Benzenamine, 3 chloro 2,6 dinitro N, N dipropyl 4 ( trifluoromethyl) ( CAS No. 29091   20   1) ( 48th Report, Ref. 2); stannane, dimethylbis[( 1 oxoneodecyl) oxy] ( CAS No. 68928   76   7) ( 49th Report, Ref. 3); and benzene, 1,3,5 tribromo 2( 2 propenyloxy) ( CAS No. 3278   89   5) and 1 triazene, 1,3 diphenyl ( CAS No. 136   35   6) ( 50th Report, Ref. 4). The ITC requests that USEPA add the 43 vanadium compounds described in this 51st Report to the TSCA section 8( a) PAIR rule.

D. Rescinding Requests to Add Chemicals to TSCA Section 8( a) PAIR Rules The ITC is rescinding its 48th Report ( Ref. 2) request to add 3H pyrazol 3 one, 5[( 2 chloro 5 nitrophenyl) amino] 2,4 dihydro 2 ( 2,4,6 trichlorophenyl) ( CAS No. 30707   68   7) to the TSCA section 8( a) PAIR rule because of decreasing production volume trends from 1990 to the present. The ITC is also rescinding its 48th Report ( Ref. 2) request to add phenol, 4,4'[ 2,2,2 trifluoro 1 ( trifluoromethyl) ethylidene] bis ( CAS No. 1478   61   1) to the TSCA section 8( a) PAIR rule because the ITC has learned that the predicted bioconcentration factor ( BCF) of 500 is below the BCF threshold currently considered for action by USEPA under its Persistent, Bioaccumulative and Toxic ( PBT) Chemical Program ( http:// www. epa. gov/ opptintr/ pbt).

E. Previous Requests to Add Chemicals to TSCA Section 8( d) HaSDR Rules The ITC has requested in previous reports to the USEPA Adminstrator that the following chemicals be added to TSCA section 8( d) HaSDR rules: 3H 1,2,4 triazole 3 thione, 5 amino 1,2 dihydro ( 3 amino 5 mercapto 1,2,4 triazole) ( CAS No. 16691   43   3) and imidazo[ 4,5 d] imidazole 2,5( 1H, 3H) dione, tetrahydro ( glycoluril) ( CAS No.

At this time, the ITC is requesting that USEPA 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 this report. For 3H 1,2,4 triazole 3 thione, 5 amino 1,2 dihydro ( 3 amino 5 mercapto 1,2,4 triazole) and imidazo[ 4,5 d] imidazole 2,5( 1H, 3H) dione, tetrahydro ( glycoluril), the ITC requests 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% of the test substance by weight should be submitted. For the 9 indium compounds remaining on the Priority Testing List, the ITC requests that the TSCA section 8( d) HaSDR rule require the submission of pharmacokinetics, genotoxicity, subchronic and chronic toxicity, and reproductive effects and developmental toxicity studies. Only studies where indium compounds are   90% of the test substance by weight should be submitted. For benzenamine, 3 chloro 2,6 dinitro N, 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, N dipropyl 4 ( trifluoromethyl) is   90% of the test substance by weight should be submitted. For stannane, dimethylbis[( 1 oxoneodecyl) oxy], the ITC requests that the TSCA section 8( d) HaSDR rule require the submission of hydrolysis, 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% of the test substance by weight should be submitted. For benzene, 1,3,5 tribromo 2( 2 propenyloxy), the ITC requests that the TSCA section 8( d) HaSDR rule require the submission of biodegradation, 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.

F. Rescinding Requests to Add Chemicals to TSCA Section 8( d) HaSDR Rules The ITC is rescinding its request to USEPA to add 8 nonylphenol polyethoxylate degradation products and 28 indium compounds to the TSCA section 8( d) HaSDR rule. The request to add 8 nonylphenol polyethoxylate degradation products to the TSCA section 8( d) HaSDR rule is being rescinded because the ITC learned that they are not commercially produced ( Table 2 of this unit). Data on the 8 nonylphenol polyethoxylate degradation products were summarized in the 46th Report ( Ref. 7). The ITC is rescinding its request to add 28 indium compounds to the TSCA section 8( d) HaSDR rule because no PAIR reports were submitted for these chemicals in response to the July 26, 2001, PAIR rule ( 1,000 pound reporting threshold) ( Ref. 8). Data on the indium compounds were summarized in the 47th Report ( Ref. 6).

A. Voluntary Information Submissions To promote more efficient use of information submission resources, the ITC developed the VISP and the VISION. The VISP is described in the ITC's 41st Report ( Ref. 9), while the VISION is described in the ITC's 42nd Report ( Ref. 5). The ITC developed the VISP and VISION as tools to provide a more cost effective method for chemical producers, importers, processors, and users of ITC recommended chemicals to provide voluntary information. Except for a few industries, the ITC received voluntary information submissions through the VISION on < 15% of the chemicals for which voluntary information was solicited. The ITC has not yet determined the reasons for the apparent low utilization of the VISION. In its 50th Report ( Ref. 4), the ITC requested comments on procedures that could be implemented to make the VISION or other procedures for submitting voluntary information more effective. The American Chemistry Council ( ACC) provided an explanation of the chemical industry's limited participation in the VISION ( Ref. 10). The ACC expressed concerns about the need to protect Confidential Business Information ( CBI), the problems associated with soliciting voluntary submissions on non HPV chemicals, the potential non existence of specific data being requested by the ITC, and the resources required to submit studies in portable document format ( PDF). To supplement the efforts to obtain studies in PDF through the VISION, the ITC Staff has been contacting the producers and importers of ITCrecommended chemicals to obtain voluntary information submissions. These efforts were highly successful for the chemicals identified through DEBITS. The ITC Staff will continue to contact the producers and importers of ITC recommended chemicals to obtain voluntary information submissions as it continues its efforts to improve the utility of the VISP and VISION. During this reporting period, the ITC acknowledges the voluntary information submissions from the following organizations: 3M Corporation; Albemarle Corporation; Amfine Chemical Corporation; Alkylphenol & Ethoxylates Research Council; Akzo Nobel Chemicals, Inc.; BASF Corporation; Bayer Corporation; Biddle Sawyer Corporation; Canon USA, Inc.; Ciba Specialty Chemicals Corporation; Cognis Corporation; Crompton Corporation; E. I. duPont de Nemours and Company; Eastman Chemical Company; ExxonMobil Corporation; Great Lakes Chemical Company; Hercules, Inc.; Lonza, Inc.; Lubrizol Corporation; Magruder Color Company; Noveon, Inc.; Schenectady International, Inc.; Society of Plastics Industry; and Strucktol Company. Following the transmittal of this 51st Report to the USEPA Administrator, the ITC Staff will contact the producers and importers of the 9 indium compounds remaining on the Priority Testing List to obtain the following information to adequately access the extent and degree of exposure and potential hazard associated with indium compounds: 1. Recent non CBI estimates of annual production or importation volume trends. 2. Use information, including percentages of production or importation that are associated with different uses. 3. Estimates of the number of workers and concentrations of indium compounds to which workers may be exposed during manufacture or processing including smelting processes, leaching processes, recovery of scrap material, deposition of film coatings, soldering, and production of electrical components including, but not limited to semiconductors. B. DEBITS In its 45th through 50th Reports ( Refs. 2   4, 6, 7, and 11), the ITC described its strategies to screen and evaluate chemicals with persistence and bioconcentration potential. These activities are referred to as DEBITS. DEBITS provides a means to prioritize chemicals for information reporting and testing based on degradation and bioconcentration potential and availability of effects data. For DEBITS 1, the ITC used criteria to screen 12,685 chemicals and ultimately review 458, the disposition of which was described in the 45th through 50th Reports ( Refs. 2   4, 6, 7, and 11). As a result of implementing DEBITS 1, the Priority Testing List contains three chemicals with persistence and bioconcentration potential that the USEPA may consider for its PBT Program: Benzenamine, 3 chloro 2,6 dinitro N, N dipropyl 4 ( trifluoromethyl); stannane, dimethylbis[( 1 oxoneodecyl) oxy]; and benzene, 1,3,5 tribromo 2( 2 propenyloxy). DEBITS 2 started with 8,511 chemicals with production volumes > 10,000 lbs reported to USEPA in response to the 1998 Inventory Update Rule ( IUR). From these 8,511 chemicals, 30 non HPV chemicals were identified that had 1998 production volumes > 50,000 lbs, predicted biodegradation half lives > 2 months and predicted bioconcentration factors > 1,000. The ITC contacted manufacturers and importers of these 30 DEBITS 2 chemicals to solicit voluntary information on production and uses, and unpublished toxicity data. The ITC received production and use information for 22 DEBITS 2 chemicals and unpublished toxicity studies for 13 DEBITS 2 chemicals. After reviewing this and other available information the ITC deferred the 30 DEBITS 2 chemicals for information reporting rules. A brief rationale for deferring each DEBITS 2 chemical is given in Table 3 of this unit.

Revisions to the TSCA Section 4( e) Priority Testing List A. Chemicals Added to the Priority Testing List: Vanadium Compounds 1. Recommendation. Forty three vanadium compounds are being added to the Priority Testing List to obtain importation, production, use, exposure, and health effects information to meet U. S. Government data needs ( Table 4 of this unit). These compounds were identified by searching reference sources and chemical databases maintained by agencies in the United States and Canada. The ITC believes the list of vanadium compounds in Table 4 of this unit includes those most likely to be in current use. Toxicological effects of vanadium compounds were recently summarized by the International Program on Chemical Safety under the auspices of the World Health Organization ( WHO) ( Ref. 13).

Long term inhalation exposure to vanadium pentoxide increased the incidence of lung tumors in male and female mice. As a result, vanadium pentoxide and other vanadium compounds may be potentially carcinogenic to humans. Existing occupational exposure limits for vanadium dusts were primarily developed to protect workers from irritation and acute pulmonary effects and may not be sufficiently protective against an increased risk of lung cancer. 3. Information needs. The ITC needs: i. Recent non CBI estimates of annual production or importation volume data and trends, and use information, including percentages of production or importation that are associated with different uses. ii. Estimates of the number of humans and concentrations of vanadium chemicals to which humans may be exposed in each relevant manufacturing or processing scenario. iii. Health effects data including pharmacokinetics, genotoxicity, subchronic toxicity, reproductive and developmental toxicity, and any human data from occupationally exposed workers. The ITC seeks this information in order to adequately assess the extent and degree of exposure and potential hazard associated with the various forms of vanadium. 4. Supporting information. Vanadium is widely distributed in low amounts as a constituent of mineral ores and crude petroleum deposits. The U. S. consumption of vanadium compounds was reported to be 3,210 metric tons in 2001 ( Ref. 14). The majority of vanadium was utilized as an alloying agent in the steel industry or in the production of ferrovanadium and other metal alloys. A smaller portion of vanadium was used as industrial catalysts and in the production of pesticides, dyes, inks, and pigments. More recent applications of vanadium compounds are thought to include manufacture of semiconductors, vanadate glasses, and electro optical switches. There were over 5,000 potentially exposed workers reported in the National Occupational Exposure Survey conducted between 1980 and 1983. Vanadium exposure has been found in over 300 personal air samples reported in OSHA's Integrated Management Information System since 1995. Worker exposures are known to occur during manufacture and handling of vanadium containing materials, such as welding operations or during cleaning of oil fired furnaces and boilers. General population exposure to vanadium most likely occurs through ingestion of food bearing soil residue and inhaled air in areas with high levels of residual fuel oil consumption ( Ref. 15). For vanadium pentoxide and most vanadium dusts and fumes, NIOSH's Recommended Exposure Limit ( REL) is a ceiling value of 0.05 milligram/ meter cubed ( mg/ m3). The American Council of Government Industrial Hygienists ( ACGIH) threshold limit value ( TLV) for vanadium pentoxide is 0.05 mg/ m3 as an 8   hour time weighted average. OSHA's Permissible Exposure Limit ( PEL) is a 0.1 mg/ m3 ceiling for vanadium pentoxide fumes and a 0.5 mg/ m3 ceiling for respirable dust. These occupational exposure limits were developed to protect against respiratory tract irritation and acute pulmonary effects and may not be adequate against an increased risk of lung cancer. In a 2 year inhalation study, NTP found clear evidence of carcinogenic activity of vanadium pentoxide ( CAS No. 1314   62   1) in male and female VerDate Jan< 31> 2003 15: 11 Feb 25, 2003 Jkt 200001 PO 00000 Frm 00010 Fmt 4701 Sfmt 4703 E:\ FR\ FM\ 26FEN3.

The incidence of benign and malignant neoplasms was increased in the lungs of the experimental animals at doses of 1, 2, and 4 mg/ m3. There was also some lesser evidence of increased lung tumor incidence in male and female rats at similar exposure levels. Exposures to vanadium pentoxide caused a spectrum of nonneoplastic lesions in the respiratory tracts of rats and mice, including epithelial hyperplasia, inflammation and fibrosis. The NTP report raises concerns for other vanadium chemicals and their potential health effects.

B. Chemicals Removed From the Priority Testing List 1. Thiophenol. Thiophenol ( CAS No. 108   98   5) was designated in the ITC's 28thReport ( Ref. 16) because there was a low confidence in the Reference Dose ( RfD) and no Reference Concentration ( RfC). The USEPA's RfC/ RfD Workgroup requested that the ITC review health effects data for thiophenol and recommend health effects testing that would increase the confidence in the RfD and provide a RfC. Since thiophenol was designated, the ITC has learned that it is not currently produced in the United States, that the NTP has conducted developmental toxicity ( Refs. 17 and 18) and reproductive effects ( Ref. 19) studies, and that Japan is developing a SIDS dossier. Thiophenol is being removed from the Priority Testing List because it is no longer produced and the ITC anticipates the SIDS dossier will address the testing data needs recommended by the ITC. 2. Seven alkylphenols and alkylphenol ethoxylates. The ITC is continuing to review data on the alkylphenols and alkylphenol ethoxylates that were recommended in ITC Reports 37 ( Ref. 20), 39 ( Ref. 21), and 41 ( Ref. 9). For these chemicals the ITC has reviewed the PAIR reports submitted by producers and voluntary information provided by the Alkylphenol & Ethoxylates Research Council ( APERC). At this time the ITC is removing from the Priority Testing List 4 alkylphenols from the 37th Report ( Ref. 20) 1 nonylphenol ethoxylate from the 39th Report ( Ref. 21) and 2 alkylphenols from the 41st Report ( Ref. 9) ( Table 5 of this unit).

CAS No. 1987   50   4 for Phenol, 4 heptyl denotes a linear structure of the C7 chain and was previously used and reported on the IUR though it is not the most appropriate CAS number for the commercial heptylphenol product.

There are 2 alkylphenols from the 37th Report ( Ref. 20) and 1 alkylphenol from the 41st Report ( Ref. 9) remaining on the Priority Testing List ( Table 6 of this unit).

For phenol, 4( 1,1 dimethylethyl) ( CAS No. 98   54   4), the ITC anticipates reviewing the SIDS dossier and the ongoing reproductive effects study. For phenol, 4( 1,1,3,3 tetramethylbutyl) ( CAS No. 140   66   9) and phenol, 4 nonyl, branched ( CAS No. 84852   15   3), the ITC anticipates receiving amphibian toxicity data, avian reproductive effects data, and fish reproductive effects data. 3. DEBITS 1 chemical. 3H Pyrazol 3 one, 5(( 2 chloro 5 nitrophenyl) amino) 2,4 dihydro 2( 2,4,6 trichlorophenyl) is being removed from the Priority Testing List because of decreasing production volume trends from 1990 to the present. Phenol, 4,4'[ 2,2,2 trifluoro 1 ( trifluoromethyl) ethylidene] bis is being removed from the Priority Testing List because the ITC has learned that the predicted BCF of approximately 500 is not sufficient to be considered by USEPA's PBT Program. Pentachlorothiophenol ( CAS No. 133   49   3) is being removed from the Priority Testing List because of low exposure potential from current use.
