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.

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\st\ ITC Report

    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 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 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

1319-77-3                                   Phenol, 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).
