Make sure to submit your comments by the comment period deadline identified. II. Background The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq.) authorizes the Administrator of 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 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. You may access additional information about the ITC at https:// www.epa.gov/opptintr/itc. A. The 62\nd\ ITC Report The ITC is revising the TSCA section 4(e) Priority Testing List by removing four tungsten compounds and four cresols. B. Status of the Priority Testing List The Priority Testing List includes 2 alkylphenols, 1 tungsten compound, 12 lead compounds, 16 chemicals with insufficient dermal absorption rate data, and 208 High Production Volume (HPV) Challenge Program orphan chemicals.

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 website (https://www.epa.gov/opptintr/itc) within a few days of submission to the EPA Administrator and from the EPA's website (https:// 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, ITC members, and their U.S. Government [[Page 27452]] 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, 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) or TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rules. The PAIR rule requires manufacturers (including importers) of chemicals added to the Priority Testing List to submit to EPA certain production and exposure information (https:// www.epa.gov/oppt/chemtest/pubs/pairform.pdf). As provided for in the PAIR rule, whenever EPA announces the receipt of an ITC report, EPA amends, unless otherwise instructed by the ITC, the PAIR rule by adding the recommended (or designated) chemicals that have been added to the Priority Testing List by the ITC. The HaSDR rule requires certain past, current, and proposed manufacturers, importers, and (if specified by EPA) processors of listed chemicals to submit to EPA copies and lists of unpublished health and safety studies on the listed chemicals that they manufacture, import, or (if specified by EPA) process. As provided for in the HaSDR rule, whenever EPA announces the receipt of an ITC report, EPA amends, unless otherwise instructed by the ITC, the HaSDR rule by adding the recommended (or designated) chemicals that have been added to the Priority Testing List by the ITC. 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 the 52\nd\ ITC Report (https://www.epa.gov/opptintr/itc). III. ITC's Activities During this Reporting Period (December 2007 to May 2008) During this reporting period, the ITC discussed tungsten compounds and cresols. IV. Revisions to the TSCA Section 4(e) Priority Testing List: Chemicals Removed from the Priority Testing List A. Tungsten Compounds Of the 22 tungsten compounds added to the Priority Testing List in the 53\rd\ ITC Report (Ref. 1) and the 56\th\ ITC Report (Ref. 2), 12 were removed in the 58\th\ ITC Report (Ref. 3), and 5 were removed in the 59\th\ ITC Report (Ref. 4). At this time the ITC is removing 4 tungsten compounds from the Priority Testing List (see Table 2 of this unit). Table 2.--Tungsten Compounds Being Removed From the Priority Testing List ------------------------------------------------------------------------ CAS No. Chemical Name ------------------------------------------------------------------------ 1314-35-8 Tungsten oxide (WO3) ------------------------------------------------------------------------ 7440-33-7 Tungsten ------------------------------------------------------------------------ 11120-25-5 Tungstate (W12(OH)2O40\10\- ), ammonium (1:10) ------------------------------------------------------------------------ 13472-45-2 Tungstate (WO4\2\-), sodium (1:2), (T-4)- ------------------------------------------------------------------------ Prior to removing these 4 tungsten compounds, the PAIR reports submitted in response to the December 7, 2004, PAIR rule (Ref. 5) were reviewed. The ITC is removing tungstate (W 12 (OH)2 O40 \10\-), ammonium (1:10) and tungstate (WO4 \2\-), sodium (1:2), (T-4)- because the data submitted in response to the December 7, 2004 PAIR rule suggested low potential for occupational exposure. The ITC is removing tungsten from the Priority Testing List because the toxicological profile for tungsten (https://www.atsdr.cdc.gov/ toxprofiles/tp186.html) summarizes the health effects information. The ITC is removing tungsten oxide (WO3 ), a.k.a. tungsten trioxide because of the voluntary information provided by the International Tungsten Industry Association and their cooperation in a National Toxicology Program/National Institute for Occupational Safety and Health research program to address exposure and toxicity data needs. The ITC is retaining tungstate (WO4 \2\-), disodium, dihydrate, (T-4)-, a.k.a. sodium tungstate (Na2 (WO4 )), dihydrate (CAS No. 10213-10-2), on the Priority Testing List because of ongoing discussions with the International Tungsten Industry Association to obtain: 1. Recent non-Confidential Business Information estimates of annual production or importation volume data and trends, and chemical- specific use information, including percentages of production or importation that are associated with different uses. 2. Estimates of the number of exposed humans and concentrations of sodium tungstate, dihydrate to which humans may be exposed in each relevant manufacturing, processing, or other occupational scenario. 3. Case studies from occupationally exposed workers and pharmacokinetics, dermal, inhalation, as well as any oral acute toxicity, subchronic toxicity, chronic toxicity, genotoxicity, carcinogenicity, neurotoxicity, reproductive and developmental toxicity, and epidemiology studies. B. Cresols Cresols were added to the Priority Testing List in the 61\st\ ITC Report to obtain unpublished data on dermal sensitization (Ref. 6). The four cresols are listed in Table 3 of this unit. Table 3.--Cresols Being Removed From the Priority Testing List ------------------------------------------------------------------------ TSCA Inventory CAS No. Name Common Name ------------------------------------------------------------------------ 95-48-7 Phenol, 2-methyl- o-Cresol ------------------------------------------------------------------------ 106-44-5 Phenol, 4-methyl- p-Cresol ------------------------------------------------------------------------ 108-39-4 Phenol, 3-methyl- m -Cresol ------------------------------------------------------------------------ 1319-77-3 Phenol, methyl- Mixed Cresols ------------------------------------------------------------------------ In response to the 61\st\ ITC Report, the Cresols Panel of the American Chemistry Council (ACC) submitted a February 27, 2008 letter to EPA's Office of Pollution Prevention and Toxics Document Control Office (Ref. 7). The Cresols Panel also submitted several references which are summarized in this unit. In a 1972 report to the Research Institute for Fragrance Materials, Kligman performed a maximization test on 25 volunteers and determined that p-cresol at 4% concentration in petrolatum produced no sensitization reactions (Ref. 8). In a 1980 report to the Research Institute for Fragrance Materials, Kligman performed a maximization test on 25 volunteers and determined that o- cresol at 4% concentration in petrolatum produced no sensitization reactions (Ref. 9). In later reports, Bruze (1986) showed that guinea pigs sensitized with 2-methylolphenol (CAS No. 623-05-2) or 4-methylolphenol (CAS No. 90-01-7) and challenged with o-cresol or p-cresol following a guinea pig maximization test protocol react positively at re-challenge with both o- and p-cresol (Ref. 10). Bruze and Zimerson (1997) challenged patients with known contact allergy to phenol-formaldehyde resin and methylol phenol to o-cresol and p-cresol and found that 4 of 10 patients were sensitive to o-cresol, and 1 of 2 patients were sensitive to p-cresol (Ref. [[Page 27453]] 11). Bruze and Zimerson (2002) established a dose-response relationship to cresol sensitization (Ref. 12). Seidenari et al. (1991) patch-tested adult patients that were sensitized to textile dyes for reaction to m- cresol and found that there were positive effects in 2 of 81 patients tested with 2% m-cresol (Ref. 13). These findings were summarized in the 2006 Cosmetic Ingredient Review (Ref. 14). At this time there do not appear to be any dermal sensitization studies with mixed cresols. After reviewing the studies submitted by the Cresols Panel, it was determined that the information contained in this voluntary submission met the data needs. As a result, the ITC is removing o-cresol, p- cresol, m-cresol and mixed cresols from the Priority Testing List. V. References 1. ITC. Fifty-Third Report of the ITC.
