II. Background-

The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.) authorizes the Administrator of the 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 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 50th ITC Report

The 50th ITC Report was transmitted to EPA's Administrator on May 28, 2002, and is included in this notice.

In the 50th ITC Report, the ITC:

1. Rescinds its request in the 48th ITC Report to EPA for the addition to the PAIR rule of 12 of the 15 DEBITS chemicals. The 12 DEBITS chemicals are 3 “chloroalkenes,” 5 “chlorinated trihalomethyl pyridines,” 1 “trihaloethylidene bisbenzene” (benzene, 1,1'-(2,2,2-trichloroethylidene)bis-, CAS No. 2971-22-4); and 3 “trichlorophenyldihydropyrazols” (benzamide, 3-amino-N-[4,5-dihydro-5-oxo-1-(2,4,6-trichlorophenyl)-1H-pyrazol-3-yl]-, CAS No. 40567-18-8); 3H-pyrazol-3-one, 5-((5-amino-2-chlorophenyl)amino)-2,4-dihydro-2-(2,4,6-trichlorophenyl)-, CAS No. 53411-33-9; and benzamide, N-(4,5-dihydro-5-oxo-1-(2,4,6-trichlorophenyl)-1H-pyrazol-3-yl)-3-nitro-, CAS No. 63134-25-8.

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 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 49 semi-annual (May and November) reports to the EPA 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, 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.

The 50th ITC Report marks a significant milestone for the ITC. Since its first meeting on February 5, 1977, the ITC has convened 425 meetings, screened thousands of chemicals, and reviewed more than 2,500 organic, organo-metallic, and inorganic chemicals to identify those with suspicions of toxicity, environmental release, and consumer or occupational exposures, but few, if any data (Ref. 14). In its 50 Reports, the ITC has added to the Priority Testing List and recommended testing or information reporting for 81 individual chemicals and 80 chemical groups (about 1,400 chemicals) for priority consideration by the EPA Administrator. In response, the EPA has published 200 Federal Register notices and reviewed hundreds of test protocols and data submissions and the U.S. chemical industry has developed over 1,000 tests and submitted more than 75,000 unpublished health and safety studies to the EPA.

As of 1992, testing was ongoing, proposed, under consideration, required or voluntarily conducted for 85% of the chemicals and chemical groups recommended by the ITC (Ref. 14). Many of the data developed as a result of ITC's recommendations have been incorporated into Material Safety Data Sheets, used by U.S. Government and industry organizations to develop hazard assessments and included in the Organization for Economic Cooperation and Development (OECD) Screening Information Data Set (SIDS) dossiers (e.g., 100% of the Start Printed Page 49533chemicals in phase I of the OECD SIDS program were reviewed by the ITC prior to preparation of SIDS dossiers), (Ref. 14). Well-known examples of chemicals for which data have been developed as a result of ITC recommendations include alkyl phthalates, chlorinated paraffins and hexachlorobutadiene (Ref. 1), acrylamide, aryl phosphates, methylene chloride and trichloroethane (Ref. 2), chlorinated benzenes (Refs. 1 and 3), benzidine-, o-dianisidine- and o-toluidine-based dyes (Ref. 4), phenylenediamines (Ref. 5), alkyl tins and fluoroalkenes (Ref. 6), octylphenol (Ref. 7), bisphenol A (Ref. 8), tetrabromobisphenol A (Ref. 9), methyl tertiary butyl ether or MTBE (Ref. 10), and brominated flame retardants, including brominated diphenyl ethers (Ref. 11).

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) promulgates TSCA section 8(a) PAIR and TSCA section 8(d) HaSDR rules for chemicals added to the Priority Testing List. 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 under TSCA section 8(a). 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 (63 FR 15765, April 1, 1998) (FRL-5750-4) codified at 40 CFR part 716. All submissions must be received by the EPA 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. Under the ITC's VISION and VISP, promulgation of HaSDR rules for most chemicals that are added to the Priority Testing List has been delayed to allow voluntary submission of studies of specific interest (see section II.C. for further details on VISION and VISP). -

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; ITC voluntary 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.-

C. Promoting More Efficient Use of Information Submission Resources

To promote more efficient use of information submission resources, the ITC developed the VISP and VISION. The VISP provides examples of data needed by ITC member U.S. Government organizations, examples of studies that should not be submitted, the milestones for submitting information, guidelines for using the TSCA Electronic HaSDR Form and instructions for electronically submitting full studies. The VISP is described in the ITC's 41st Report (63 FR 17658, April 9, 1998) (FRL-5773-5) and is accessible through the world wide web (http://www.epa.gov/​opptintr/​itc/​visp.htm ). To facilitate the implementation of the VISP, the ITC developed the VISION. The VISION is described in the ITC's 42nd ITC Report (63 FR 42554, August 7, 1998) (FRL-5797-8) and is also accessible through the world wide web (http://www.epa.gov/​opptintr/​itc/​vision.htm). The VISION includes links to the TSCA Electronic HaSDR Form (http://www.epa.gov/​opptintr/​.er/​hasd.htm) including revised section 3.2 of the TSCA Electronic HaSDR Form to provide more use and exposure information (for details see the 46th ITC Report; 65 FR 75552, December 1, 2000) (FRL-6594-7). -

The ITC requests that chemical producers, importers, processors, and users provide information electronically via VISION on chemicals for which the ITC is soliciting voluntary information. If the ITC does not receive voluntary information submissions to meet its data needs according to the procedures in VISP, the ITC may then ask the EPA to add those chemicals to a TSCA section 8(d) HaSDR rule to determine if there are unpublished data to meet those needs (see section III.A. that requests comments on the need to continue VISION and VISP). -

D. Coordinating Information Rrequests

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, the OECD SIDS program and the EPA's High Production Volume (HPV) Challenge program). The ITC is currently focusing its efforts on persistent non-HPV chemicals that have bioconcentration and exposure potential, but few, if any, publicly available ecological or health effects data. The ITC is working with the EPA Persistent Bioaccumulative Toxics (PBT), Endocrine Disruption, and perfluoroctylsulfonate chemicals workgroups to identify potentially toxic chemicals with few data to complement the objectives of those programs.-

E. Requests to Promulgate TSCA Section 8(a) PAIR and Section 8(d) HaSDR Rules

The ITC asked the EPA to add 3 chloroalkenes to the TSCA section 8(a) PAIR rule in its 48th ITC Report (66 FR 51276, October 5, 2001) (FRL-6786-7). In addition, the ITC asked the EPA to add 5 chlorinated trihalomethyl pyridines, 2 trihaloethylidene bisbenzenes, 4 trichlorophenyldihydropyrazols, and 3-chloro-2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)-benzeneamine to the TSCA section 8(a) PAIR rule in its 48th ITC Report (66 FR 51276, October 5, 2001).-

At this time, the ITC is rescinding its request to add the 3 chloroalkenes; 5 chlorinated trihalomethyl pyridines; 1 of the trihaloethylidene bisbenzenes (benzene, 1,1'-(2,2,2-trichloroethylidene)bis-, CAS No. 2971-22-4); and 3 of the trichlorophenyldihydropyrazols (benzamide, 3-amino-N-[4,5-dihydro-5-oxo-1- (2,4,6-trichlorophenyl)-1H-pyrazol-3-yl, CAS No. 40567-18-8, 3H-pyrazol-3-one, 5-((5-amino-2-chlorophenyl)amino)-2,4-dihydro-2-(2,4,6-trichlorophenyl)-, CAS No. 53411-33-9, and benzamide, N-(4,5-dihydro-5-oxo-1-(2,4,6-trichlorophenyl)-1H-pyrazol-3-yl)-3-nitro-, CAS No. 63134-25-8) to the TSCA section 8(a) PAIR rule, either because no production or importation data were submitted to the EPA in response to the 1998 Inventory Update Rule (IUR) or because the predicted bioconcentration factors (BCFs) were judged to be too low to warrant priority consideration at this time. -

The ITC is not rescinding its request to add 3-chloro-2,6-dinitro-N,N-dipropyl-4- (trifluoromethyl)-benzeneamine (CAS No. 29091-20-1), 3H-pyrazol-3-one, 5-((2-chloro-5- nitrophenyl)amino)-2,4-dihydro-2-(2,4,6-trichlorophenyl)- (CAS No. 30707-68-7), and phenol, 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis- (CAS No. 1478-61-1) to the TSCA section 8(a) PAIR rule.-

At this time, the ITC is also asking the EPA to add 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) to the TSCA section 8(a) PAIR rule. Stannane, dimethylbis[(1-oxoneodecyl)oxy]- and benzene, 1,3,5-tribromo-2-(2-propenyloxy)- are being added to the TSCA section 8(a) PAIR rule, because they are estimated to persist and have predicted BCFs of 8,650 and 4,019, respectively, few toxicity data and a need for additional use and exposure data, beyond that provided by the manufacturers. 1-Triazene, 1,3-diphenyl is being added to the TSCA section 8(a) PAIR rule, because it is a predicted carcinogen based on its metabolism and because the ITC needs occupational exposure data.-

At this time, the ITC is also asking the EPA to add stannane, dimethylbis[(1-oxoneodecyl)oxy]-, benzene, 1,3,5-tribromo-2-(2-propenyloxy)- and 1-triazene, 1,3-diphenyl to the TSCA section 8(d) HaSDR rule. Stannane, dimethylbis[(1-oxoneodecyl)oxy]- is being added to the TSCA section 8(d) HaSDR rule, because the ITC needs to know if there are other toxicity data in addition to that described in section IV.A.2. and 3. of the 49th Report (67 FR 10298, March 6, 2002) (FRL-6820-8).

III. ITC's Activities During this Reporting Period (November 2001 to April 2002)-

A. VISION-

The ITC is the only organization for which the EPA can promulgate direct TSCA section 8(d) HaSDR final rules. As such, when the EPA convened public meetings to discuss revisions to the TSCA section 8(d) HaSDR rule (63 FR 15765, April 1, 1998) (FRL-5750-4), the ITC was invited to provide and respond to comments on this rule. One of the most consistent comments by the chemical industry was that the ITC should offer more opportunities to provide voluntary information submissions (to avoid the mandatory requirements of submitting information in response to a TSCA section 8(d) HaSDR rule). In response to these chemical industry requests, the ITC developed VISP, VISION, and the TSCA Electronic HaSDR Form, and is currently evaluating their effectiveness.-

The ITC developed VISP, VISION, and the TSCA Electronic HaSDR Form as tools to provide a more cost-effective method for chemical producers, importers, processors, and users of ITC-recommended chemicals to provide voluntary information. With the exception of 3 trade organizations, the Alkylphenols & Ethoxylates Research Council (APERC), the Color Pigment Manufacturers Association (CPMA), and the Ecological and Toxicological Association of Organic Dye Manufacturers (ETAD), and 4 manufacturers, 3M Specialty Materials, Ciba Speciality Chemicals, E. I. du Pont de Nemours and Company, and Rohm and Haas Company, these tools have not been used by chemical producers, importers, processors, and users of ITC-recommended chemicals. The ITC has received voluntary information submissions on <15% of the approximately 500 chemicals for which the ITC has solicited voluntary information since implementing the VISP and VISION, in effect delaying the ITC's ability to obtain the information it needs to make decisions and meet U.S. Government data needs.

The ITC recognizes that there are increasing demands on the chemical industry to provide information in response to voluntary initiatives, e.g., the OECD SIDS program, EPA HPV Challenge program and Voluntary Children's Chemical Evaluation Program (VCCEP). The ITC supports and coordinates its voluntary information requests with these programs. However, as a statutory-mandated organization charged with screening and identifying potentially hazardous chemicals, the ITC also recognizes that the chemical industry has the responsibility under TSCA and under the principles of Responsible Care® and Chemical Right-to-Know, to promptly and voluntarily provide information on the ITC's recommended chemicals to be used in subsequent hazard, exposure, and risk assessments by the U.S. Government organizations represented on the ITC.

The ITC is considering whether to continue the use of the VISP, VISION, and the TSCA Electronic HaSDR Form for chemicals added to the Priority Testing List, as the lack of use of these tools has resulted in substantial delays in obtaining information that could be used to meet the ITC's data needs. The ITC requests comments on procedures that could be implemented to make these existing tools or other procedures for submitting voluntary information more effective. Comments in a word processing file attached to an e-mail to walker.johnd@epa.gov are preferred, but the ITC will also accept comments submitted to Dr. John D. Walker at the address listed at the end of this Report by September 30, 2002.

B. DEBITS

In its 45th through 49th ITC Reports, 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.

Prior to this reporting period the ITC made information reporting or testing deferral decisions on 206 DEBITS chemicals. During this reporting period, the ITC completed its review of the remaining 252 DEBITS chemicals, including the 9 chemicals discussed in this section:

1. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5),

2. 2,9-Dimethylquinacridone (CAS No. 980-26-7),

3. 1,2-Ethanediyl tetrakis (2-chloro-1- methylethyl) phosphate (CAS No. 34621-99-3),

4. Oxirane, 2,2',2''-(methylidynetris(phenyleneoxymethylene))(tris- (CAS No. 66072-38-6),

5. P-cresol, 2,6-di-tert-butyl-alpha-(dimethylamino) (CAS No. 88-27-7),

6. Spiro isobenzofuran-1(3H),9'-9H xanthen-3-one, 3',6'-bis(ethylamino)-2',7'-dimethyl- (CAS No. 41382-37-0),

7. 1H-indole-2-carboxaldehyde, 2,3-dihydro-2-hydroxy-1,3,3-trimethyl-(4-methoxyphenyl) methylhydrazone (CAS No. 81241-99-8),

8. Phenoxazin-5-ium, 3,7-bis(diethylamino)-, (T-4)-tetrachlorozincate(2-) (2:1) (CAS No. 63589-47-9), and

9. Oxirane, 2-[2-(4-chlorophenyl)ethyl]-2-(1,1-dimethylethyl)- (CAS No. 80443-63-6).

The ITC is adding benzene, 1,3,5-tribromo-2-(2-propenyloxy)- to the Priority Testing List as discussed in section IV.A.1. The ITC deferred making a testing recommendation for 2,9-dimethylquinacridone because its absorption potential into mammalian tissues is expected to be low based on absorption data for the structurally related EPA HPV Challenge chemical, 5,12-dihydroquino(2,3-b)acridine-7,14-dione (CAS No. 1047-16-1). 1,2-Ethanediyl tetrakis (2-chloro-1- methylethyl) phosphate was previously removed from the Priority Testing List in the ITC's 36th ITC Report (60 FR 42982, August 17, 1995) (FRL-4965-6).

Oxirane, 2,2',2''-(methylidynetris (phenyleneoxymethylene))tris- was deferred for testing because its predicted hydrolysis half life was 3 days. The ITC deferred making testing recommendations for p-cresol, 2,6-di-tert-butyl-alpha-(dimethylamino); spiro isobenzofuran-1(3H),9'-9H xanthen-3-one, 3',6'-bis(ethylamino)-2',7'-dimethyl-; 1H-indole-2-carboxaldehyde, 2,3-dihydro-2-hydroxy-1,3,3-trimethyl-(4-methoxyphenyl) methylhydrazone; and phenoxazin-5-ium, 3,7-bis(diethylamino)-, (T-4)-tetrachlorozincate(2-) (2:1) because of their low-exposure potential. Oxirane, 2-[2-(4-chlorophenyl)ethyl]-2-(1,1-dimethylethyl)- was deferred for testing because it is likely to be tested under one of the voluntary HPV chemical testing programs.

The remaining 243 DEBITS chemicals deferred for testing include 7 DEBITS chemicals with predicted BCFs <1,000 (see Table 2 of this appendix), 28 EPA HPV Challenge program DEBITS chemicals (see Table 3 of this appendix), and 208 non-HPV DEBITS chemicals with predicted BCFs of 3-13 (see Table 4 of this appendix).

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

A. Chemicals Added to the Priority Testing List--

1. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- —i. Recommendation. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5) is recommended to obtain unpublished exposure, environmental fate, health effects, and ecological effects data.---

ii. Rationale for recommendation. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is predicted to persist and bioconcentrate. There are very few toxicity data. Depending on the exposure, environmental fate, health effects, and ecological effects data that are provided, the EPA may consider benzene, 1,3,5-tribromo-2-(2-propenyloxy)- for their PBT Initiative.----

iii. Supporting information. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is produced in excess of 500,000 pounds per annum and used as a flame retardant for expanded polystyrene insulation board. The predicted BCF of benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is 4,019. The rat oral LD50 was 5 grams/kilograms (g/kg) and it was not mutagenic in an Ames assay. A TOXLINE search identified one report that benzene, 1,3,5-tribromo-2-(2-propenyloxy)- was detected in sewer slime (Ref. 13).---

iv. Information needs. The ITC needs exposure, environmental fate, health effects, and ecological effects data. Only studies where benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is > 90% of the test substance by weight should be submitted.--

2. 1-Triazene, 1,3-diphenyl—i. Recommendation. 1-Triazene, 1,3-diphenyl (diazoaminobenzene) (CAS No. 136-35-6) is being recommended to obtain annual production/importation volumes and trends, use, exposure, and health effects data.---

ii. Rationale for recommendation. -No occupational exposure limits have been established by the American Conference of Government Industrial Hygienists (ACGIH), the National Institute for Occupational Safety and Health (NIOSH), or the Occupational Safety and Health Administration (OSHA). Occupational exposures have not been characterized and there are no estimates of the number of workers exposed. The ITC needs occupational exposure data from the uses of diazoaminobenzene, e.g., to manufacture dyes and insecticides. ---

iii. Supporting information. A recent National Toxicology Program Report indicated that diazoaminobenzene is metabolized in rats and mice to the known carcinogens benzene and aniline (Ref. 12). Although not tested for carcinogenicity, diazoaminobenzene is a predicted carcinogen based on its metabolism and similarity in toxic effects to benzene and aniline. Diazoaminobenzene is used as an intermediate, complexing agent, and polymer additive. It is an impurity in certain color additives used in cosmetics, food products, and pharmaceuticals. It may also be used as a propellant for molding of rubbers and plastics and as a coupler to promote adhesion of natural rubber to steel tire cords. Since diazoaminobenzene has semiconducting properties it may have applications in the semi conductor industry.---

Diazoaminobenzene may put workers at a heretofore unrecognized increased risk of cancer if they are exposed in the workplace. Importation, production, use, and exposure information will assist in determining if diazoaminobenzene may need further testing to adequately assess potential hazards associated with occupational exposures.----

iv. Information needs.—a. Recent non-CBI estimates of annual production or importation volume data and trends.-

b. Use information, including percentages of production or importation that are associated with different uses.-

c. Estimates of the number of humans and concentrations of diazoaminobenzene compounds to which humans may be exposed from use, manufacturing, or processing.-

d. Health effects data including pharmacokinetics, genotoxicity, subchronic Start Printed Page 49545and chronic toxicity, reproductive, and developmental toxicity, and any human data from occupationally exposed workers. This information is needed in order to adequately access the extent and degree of exposure and potential hazard associated with diazoaminobenzene.-

e. Only studies where diazoaminobenzene is ≥90% of the test substance by weight should be submitted.-

B. Chemicals Removed From the Priority Testing List--

1. Acetone. Acetone was designated in the ITC's 28th ITC Report for reproductive effects testing as a chemical with a low confidence reference dose or RfD (56 FR 41212, August 19, 1991) (FRL-3937-4). Acetone is being removed from the Priority Testing List because it was in the OECD SIDS program (see http://irptc.unep.ch/​irptc/​sids/​sidspub.html volume 6) and because it is included in the EPA's VCCEP for reproductive effects and developmental toxicity testing (http://www.epa.gov/​chemrtk/​childhlt.htm). The EPA anticipates that under the VCCEP, tier 2 testing for prenatal developmental toxicity, reproductive and fertility effects testing will be conducted for acetone.--

2. Twenty alkylphenols and alkylphenol ethoxylates. The ITC is continuing to review data on the alkylphenols and alkylphenol ethoxylates that were recommended in ITC's 37th ITC Report (61 FR 4188, February 2, 1996) (FRL-4991-6), 39th ITC Report (62 FR 8578, February 25, 1997) (FRL-5580-9), and 41st ITC Report (63 FR 17658 , April 9, 1998) (FRL-5773-5). At this time, the ITC is removing from the Priority Testing List, 9 alkylphenols and alkylphenol ethoxylates from the 37th ITC Report, 7 nonylphenol ethoxylates from the 39th ITC Report, and 4 alkylphenols and alkylphenol ethoxylates from the 41st ITC Report (see Table 5 of this appendix). The rationales for removing these alkylphenols and alkylphenol ethoxylates are provided as footnotes to Table 5 of this appendix.

2. No domestic production or importation volumes were reported to the EPA in response to 1986, 1990, 1994, and 1998 IURs or no domestic production or importation volumes were reported to the EPA in response to the July 5, 2000 PAIR rule (65 FR 41371) (FRL-6589-1).
3. Data developed from testing phenol, 4-(1,1,3,3-tetramethylbutyl)- (CAS No. 140-66-9) in response to the HPV Challenge program may be used to predict toxicity.
4. Data developed from testing p-dodecylphenol (CAS No. 210555-94-5) in response to the HPV Challenge program may be used to predict toxicity.
5. Data developed from testing branched nonylphenol (CAS No.84852-15-3) in response to the HPV Challenge program may be used to predict toxicity.

There are 10 alkylphenols and alkylphenol ethoxylates remaining on the Priority Testing List (see Table 6 of this appendix).

3. Three DEBITS chemicals from the 46th ITC Report. In its 46th ITC Report, the ITC discussed 2 groups of DEBITS chemicals, polychlorophenols and polychlorobenzenethiols and chlorotrifluoromethylphenoxy benzenes (65 FR 75552, December 1, 2000) (FRL-6594-7). Two of the polychlorophenols and polychlorobenzenethiols (pentachlorothiophenol, CAS No. 133-49-3 and tetrachloropyrocatechol, CAS No. 1198-55-6) and two of the chlorotrifluoromethylphenoxy benzenes (p-toluidine, 5-chloro-.alpha.,.alpha.,.alpha.-trifluoro-2-nitro-N-phenyl, CAS No. 1806-24-2 and benzoic acid, 3-[2-chloro-4-(trifluoromethyl)phenoxy]-, 2-ethoxy-1-methyl-2-oxo, CAS No. 88185-22-2) were subsequently added to the Priority Testing List in the ITC's 47th ITC Report. All 4 of these chemicals were added to the July 26, 2001 PAIR rule (66 FR 38955) (FRL-6783-6). All of these chemicals, except pentachlorothiophenol, are being removed from the Priority Testing List because no production or importation data were submitted to the EPA in response to the 1998 IUR (10,000 pound reporting threshold) or the July 26, 2001 PAIR rule (1,000 pound reporting threshold).

4. Three DEBITS chemicals from the 47th ITC Report. In its 47th ITC Report, the ITC added 3 chloroalkenes to the Priority Testing List: 1,3-butadiene, 1,1,2,3,4-pentachloro-4-(1-methylethoxy)- (CAS No. 68334-67-8); 3-butenoic acid, 2,2,3,4,4-pentachloro-butyl ester (CAS No. 75147-20-9); and 3-butenoic acid, 2,2,3,4,4-pentachloro- (CAS No. 85743-61-9). The ITC is removing these 3 chloroalkenes from the Priority Testing List because no production or importation data were submitted to the EPA in response to the 1998 IUR.

5. Nine DEBITS chemicals from the 48th ITC Report. In its 48th ITC Report, the ITC added 5 chlorinated trihalomethyl pyridines, 2 trihaloethylidene bisbenzenes, 4 trichlorophenyldihydropyrazols and 3-chloro-2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl) -benzeneamine to the Priority Testing List. The ITC is removing the 5 chlorinated trihalomethyl pyridines, 1 of the trihaloethylidene bisbenzenes (benzene, 1,1'-(2,2,2-trichloroethylidene)bis-), and 3 of the trichlorophenyldihydropyrazols (benzamide, 3-amino-N-[4,5-dihydro-5-oxo-1- (2,4,6-trichlorophenyl)-1H-pyrazol-3-yl; 3H-pyrazol-3-one, 5-((5-amino-2-chlorophenyl)amino) -2,4-dihydro-2-(2,4,6-trichlorophenyl)-; and benzamide, N-(4,5-dihydro-5-oxo-1- (2,4,6-trichlorophenyl)-1H-pyrazol-3-yl)-3-nitro-) from the Priority Testing List because no production or importation data were submitted to the EPA in response to the 1998 IUR or because the predicted BCFs were judged to be too low to warrant priority consideration at this time.
