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


### 41416 Federal Register / Vol. 72, No. 144 / Friday, July 27, 2007 / Notices

..., 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 The HaSDR rule requires manufacturers (including importers) of chemicals added to the Priority Testing List to submit unpublished health and safety studies to EPA.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).

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,


### 41417 Federal Register / Vol. 72, No. 144 / Friday, July 27, 2007 / Notices

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? ‘‘ 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).

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).

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.
