Sixtieth 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 60\th\ ITC Report to the Administrator 
of EPA on June 14, 2007. In the 60\th\ ITC Report, which is included 
with this notice, the ITC is revising the TSCA section 4(e) Priority 
Testing List by adding ``lead and lead compounds'' to the Priority 
Testing List so that EPA may expeditiously obtain unpublished health 
and safety studies that relate to the lead content of consumer products 
that are intended for use by children.

DATES: Comments must be received on or before August 27, 2007.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPPT-2007-0420, by one of the following methods:

II. Background

    The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 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

I. Background

    The ITC was established by TSCA section 4(e) ``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

[[Page 41416]]

..., 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/oppt/itc
) within a few days of submission to the EPA Administrator and from 

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) rule (40 CFR part 712) and/or the TSCA 
section 8(d) Health and Safety Data Reporting (HaSDR) rule (40 CFR part 
716). 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 manufacturers (including 

importers) of chemicals added to the Priority Testing List to submit 
unpublished health and safety studies to EPA.

B. ITC's Use of TSCA Section 8 and Other Information

     ITC's use of TSCA section 8 and other information is described in 
the 52\nd\ ITC Report (http://www.epa.gov/opptintr/itc/rptmain.htm).


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

    ITC is requesting that EPA add lead and lead compounds to the TSCA 
section 8(d) HaSDR rule. The lead and lead compounds are discussed in 
Unit IV. of this report.

III. ITC's Activities During this Reporting Period (December 2006 to 
May 2007)

    During this reporting period, the ITC discussed:
     Lead and lead compounds.
     Alkylphenols.
     Brominated flame retardants.
     Flavoring agents that cause airway obstruction during 
occupational exposures.

Lead and lead compounds are discussed in Unit IV. of this report.

    1. Alkylphenols. As noted in the 59\th\ ITC Report, the ITC is 
leaving phenol, 4-(1,1,3,3-tetramethylbutyl)- (CAS No. 140-66-9) and 
phenol, 4-nonyl-, branched (CAS No. 84852-15-3) on the Priority Testing 
List (Ref. 1). The ITC made this decision because it needed time to:
    i. Determine if the existing fish reproductive effects data are 
sufficient to meet the ITC's data needs.
    ii. Determine if phenol, 4-(1,1,3,3-tetramethylbutyl)- or phenol, 
4-nonyl-, branched should be tested for avian reproductive effects.
While the ITC is considering whether phenol, 4-(1,1,3,3-
tetramethylbutyl)- or phenol, 4-nonyl-, branched should be tested for 
avian reproductive effects, it has determined that existing fish 
reproductive effects data are sufficient to meet the ITC's data needs 
(Tables 2 and 3 of this unit).

185-Day life-cycle test with Zebra Fish (Ref. 7). Based on growth,
 time to first spawn, egg production, and fertilization success on
 fish maturing from fry to breeding adults, the NOEC and LOEC were
 12.0 and 35.0 [mu]g/L, respectively..................................
------------------------------------------------------------------------


    2. Brominated flame retardants. During discussions with the 
American Chemistry Council's Brominated Flame Retardants Industry Panel 
(BFRIP), Canadian Wildlife Service, and McGill University scientists, 
the ITC learned that the BFRIP will be sponsoring avian reproductive 
testing of 1,2,5,6,9,10-hexabromocyclododecane (CAS No. 3194-55-6) or 
hexabromocyclododecane (CAS No. 25637-99-4) using American Kestrels. 
The BFRIP provided the ITC with the International Uniform Chemical 
Information Database (IUCLID) data set for hexabromocyclododecane (CAS 
No. 25637-99-4) as well as the IUCLID data set and Voluntary Children's 
Chemical Evaluation Program (VCCEP) Tier I and II data summary for 
decabromodiphenyl ether (DBDE) (CAS No. 1163-19-5). In addition, the 
ITC discussed the National Institute of Standards and Technology's 
(NIST) ongoing work with the National Oceanic and Atmospheric 
Administration (NOAA), including the collaboration with the National 
Marine Fisheries Service (NMFS) via cooperation with the Marine Mammal 
Health and Stranding Response Program. The ITC also discussed the NOAA/
NMFS Dolphin Health Assessments, and the Seabird Tissue Archival and 
Monitoring Project to measure persistent bioaccumulative contaminants, 
including brominated flame retardants.
    3. Flavoring agents that cause airway obstruction during 
occupational exposures. The ITC discussed the National Institute for 
Occupational Safety and Health (NIOSH) alert,

[[Page 41417]]

``Preventing Lung Disease in Workers Who Use or Make Flavorings'' 
(http://www.cdc.gov/niosh/docs/2004-110), because of concerns related 

to occupational exposures to flavoring agents that may be respiratory 
irritants.

IV. Revisions to the TSCA Section 4(e) Priority Testing List: Chemicals 
Added to the Priority Testing List: Lead and Lead Compounds

    1. Recommendation. EPA requests that the ITC add the category 
``lead and lead compounds'' to the Priority Testing List (Table 4 of 
this unit).

              7446-27-7  Phosphoric acid, lead(2+) salt (2:3)
------------------------------------------------------------------------
              7758-95-4  Lead chloride (PbCl2)
------------------------------------------------------------------------
              7758-97-6  Chromic acid (H2CrO4), lead(2+) salt (1:1)
------------------------------------------------------------------------
             13814-96-5  Borate (1-), tetrafluoro-, lead(2+) (2:1)
------------------------------------------------------------------------
             53466-66-3  Silicic acid, lead salt, basic
------------------------------------------------------------------------
             63653-42-9  Sulfuric acid, lead salt (1:?), basic
------------------------------------------------------------------------

     EPA is making this request to obtain unpublished health and safety 
studies that relate to the lead content of consumer products that are 
``intended for use by children (as that term is defined at 40 CFR 
710.43)\1\ (excluding children's metal jewelry) and studies that assess 
children's exposure to lead from such products (including studies of 
bioavailability).
---------------------------------------------------------------------------

    \1\ For the purposes of this recommendation, ``Intended for use 
by children'' has the meaning provided in 40 CFR 710.43 of the TSCA 
section 8(a) Inventory Update Rule. The definition was originally 
intended for a different audience (those submitting information 
under the Inventory Update Rule) but the same concepts can apply to 
the products at issue here. The definition reads as follows:
    Intended for use by children means the chemical substance or 
mixture is used in or on a product that is specifically intended for 
use by children age 14 or younger. A chemical substance or mixture 
is intended for use by children when the submitter answers ``yes'' 
to at least one of the following questions for the product into 
which the submitter's chemical substance or mixture is incorporated:
    (1) Is the product commonly recognized (i.e., by a reasonable 
person) as being intended for children age 14 or younger?
    (2) Does the manufacturer of the product state through product 
labeling or other written materials that the product is intended for 
or will be used by children age 14 or younger?
    (3) Is the advertising, promotion, or marketing of the product 
aimed at children age 14 or younger?
---------------------------------------------------------------------------

    2. Rationale for recommendation. In pursuit of the Federal goal of 
eliminating childhood lead poisoning by 2010 (Ref. 8), EPA is looking 
beyond paint-related sources in an effort to address risks from other 
potentially significant sources. Although the Consumer Product Safety 
Commission (CPSC) has an effort underway to address risks from 
children's metal jewelry containing lead (Ref. 9), there is less 
information available on the lead content of, and exposure to lead 
from, other children's products.CPSC is currently addressing lead 
containing children's metal jewelry, but has not yet established a 
definition of these products. Thus, EPA recommends that the ITC include 
the category listing for lead and lead compounds described in Unit 
IV.1. Information obtained on this category may assist both EPA and 
CPSC in taking further action as appropriate to protect children from 
lead poisoning due to lead in products. It should be noted that for the 
purposes of regulating products by CPSC, products intended for children 
might not be defined in the same manner as for actions by EPA under 
TSCA.
    3. Supporting information. EPA has a long-standing interest in 
limiting human and environmental exposure to lead and lead compounds, 
with special concern for exposures to children. In the context of its 
Toxic Release Inventory (TRI) Program, EPA has classified lead as a 
``persistent, bioaccumulative, toxic chemical,'' (TRI Lead Rule 
published in the Federal Register of January 17, 2001 (66 FR 4500) 
(FRL-6722-4)) and in past actions has presented evidence that lead can 
cause significant deleterious health effects, particularly in children 
(e.g., Identification of Dangerous Levels of Lead; Proposed Rule 
published in the Federal Register of June 3, 1998 (63 FR 30301) (FRL-
5791-9)). A major focus of EPA has been on lead and lead compounds in 
paint, with a particular emphasis to limit lead exposures from paint 
following enactment of the ``Residential Lead-Based Paint Hazard 
Reduction Act of 1992.'' Public Law 102-550. In that Act, Congress 
emphasized its concerns about children's exposure to lead.
    CPSC recently published an Advance Notice of Proposed Rulemaking 
(ANPRM) in the Federal Register of January 9, 2007 (72 FR 920) 
addressing certain products beyond paint; CPSC is considering whether 
there may be a need to ban children's metal jewelry containing more 
than 0.06% lead by weight in metal components. In addition to 
children's metal jewelry products, EPA also believes there may be 
potential risks to children's health from exposure to other products 
intended for use by children that contain lead or lead compounds. 
However, information regarding such products is currently incomplete.
    4. Information needs. EPA is interested in health and safety 
studies that relate to the lead content of consumer products that are 
``intended for use by children'' (as defined at 40 CFR 710.43), but 
excluding ``children's metal jewelry'' as described by the CPSC in its 
ANPRM of January 9, 2007.
    For all lead and lead compounds, EPA needs the following 
information to assess the extent and degree of exposure and potential 
hazard associated with these substances:
     Studies that relate to the lead content of consumer 
products that are intended for use by children (includes studies 
showing any measurable lead content), and/or
     Studies that assess children's exposure to lead from such 
products (including studies of bioavailability).
    With regards to grade or purity, studies showing any measurable 
lead content in such products are of interest.
