Sixty-First Report of the TSCA Interagency Testing Committee to the Administrator of the Environmental Protection Agency; Receipt of Report and Request for Comments

Agency

Environmental Protection Agency (EPA).

Action

Notice.

Summary

The Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) transmitted its 61 st ITC Report to the Administrator of EPA on December 18, 2007. In the 61 st ITC Report, which is included with this notice, the ITC is revising the TSCA section 4(e) Priority Testing List by adding 4 cresols and removing 35 High Production Volume (HPV) Challenge Program orphan chemicals. The cresols were added to obtain dermal sensitization data. To obtain dermal sensitization data, including case reports of workers and any in vivo animal sensitization test data, the ITC is asking EPA to add the 4 cresols to the TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rule. The 35 HPV Challenge Program orphan chemicals are being removed from the Priority Testing List either because: Commitments were made to sponsor these chemicals under the EPA’s HPV Challenge Program, the Organization for Economic Cooperation and Development (OECD) HPV Screening Information Data Set (SIDS) Program, and/or the International Council of Chemical Associations (ICCA) HPV Initiative, or because the substances were determined by EPA to be “no longer” HPV chemical substances.

Dates

Comments must be received on or before February 27, 2008.

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 http://www.epa.gov/opptintr/itc.

A. The 61

The ITC is revising the TSCA section 4(e) Priority Testing List by adding 4 cresols and removing 35 HPV Challenge Program orphan chemicals. The cresols were added to obtain dermal sensitization data. To obtain dermal sensitization data, including case reports of workers and any in vivo animal sensitization test data, the ITC is asking EPA to add the 4 cresols to the HaSDR rule. The 35 HPV Challenge Program orphan chemicals are being removed from the Priority Testing List either because:

1. Commitments were made to sponsor these chemicals under the EPA’s HPV Challenge Program, the OECD HPV SIDS Program, and/or the ICCA HPV Initiative, or

2. Because the substances were determined by EPA to be “no longer” HPV chemical substances.

B. Status of the Priority Testing List

The Priority Testing List includes 2 alkylphenols, 4 cresols, 5 tungsten compounds, 12 lead compounds, 16 chemicals with insufficient dermal absorption rate data, and 208 HPV Challenge Program orphan chemicals.

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 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 (http://www.epa.gov/opptintr/itc) within a few days of submission to the EPA Administrator and from the EPA's website (http://www.epa.gov/fedrgstr) after publication in theFederal 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 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, the 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) HaSDR rules. 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 PAIR rule requires manufacturers (including importers) of chemicals added to the Priority Testing List to submit to EPA certain production and exposure information (http://www.epa.gov/oppt/chemtest/pubs/pairform.pdf). 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 (Ref.1).

C. New Request to Add Chemicals to the TSCA Section 8(d) HaSDR Rule

The ITC is requesting that EPA add cresols to the HaSDR rule only to obtain dermal sensitization data, including case reports of workers and any in vivo animal sensitization test data. The ITC is requesting that EPA not add cresols to the PAIR rule. The cresols are discussed in Unit IV. of this report.

III. ITC's Activities During this Reporting Period (June to November 2007)

During this reporting period, the ITC discussed cresols.

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

A. Chemicals Added to the Priority Testing List

The ITC is adding the cresols listed in Table 2 of this unit to the Priority Testing List to obtain unpublished data on dermal sensitization, including case reports of workers and any in vivo animal sensitization test data.

Table 2.—Cresols Being Added to the Priority Testing List
CAS No.Cresol
95-48-7Phenol, 2-methyl-
106-44-5Phenol, 4-methyl-
108-39-4Phenol, 3-methyl-
1319-77-3Phenol, methyl-

The ITC is aware of the skin sensitization data for phenol, 4-methyl-(p-cresol) available at http://www.oecd.org/dataoecd/17/29/34357669.pdf. While these data indicate that phenol, 4-methyl- did not cause skin sensitization, data on a mixture containing 0.6% phenol, 4-methyl- did indicate that the mixture caused skin sensitization (Ref. 2).

B. Chemicals Removed from the Priority Testing List

The ITC is removing the 35 HPV Challenge Program orphan chemicals listed in Table 3 of this unit from the Priority Testing List.

Twenty-six of the HPV Challenge Program orphan chemicals are being removed from the Priority Testing List because commitments were made to sponsor 22 chemicals in the HPV Challenge Program and 4 chemicals in either the OECD SIDS Program or the ICCA HPV Initiative (Ref. 3). Seven chemicals are being removed from the Priority Testing List because EPA no longer considers them to be HPV chemical substances (Ref. 3). Two of the HPV Challenge Program orphan chemicals are being removed from the Priority Testing List because they were incorrectly listed as HPV Challenge Program orphan chemicals (Ref. 4). Thirty-four of the HPV Challenge Program orphan chemicals are being removed from the 55 th ITC Report (Ref. 5). One HPV Challenge Program orphan chemical, 1,3-propanediol, 2-amino-2-(hydroxymethyl)-, is being removed from the 56 th ITC Report (Ref. 6).
