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 * * *, 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 Web site ( http://www.epa.gov/oppt/itc ) and from regulations.gov ( http:// www.regulations.gov ) 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 and ITC members. ITC members and staff are listed at the end of this report.

II. ITC’s Activities During This Reporting Period (June to October 2012)

During this reporting period, the ITC discussed the 164 High Production Volume (HPV) Challenge Program orphan chemicals remaining on the TSCA section 4(e) Priority Testing List. As a result of these discussions, the ITC removed 16 HPV Challenge Program orphan chemicals from the TSCA section 4(e) Priority Testing List. Orphan chemicals are those HPV chemicals for which no sponsors have volunteered to develop and submit robust summaries of basic hazard and fate testing data to the EPA. The hazard and fate testing data requested by the ITC for HPV Challenge Program orphan chemicals are necessary to establish a screening level understanding of their potential human health and environmental impacts. III. HPV Challenge Program Orphan Chemicals Removed From the TSCA Section 4(e) Priority Testing List

The Chemical Abstract Service (CAS) Registry numbers and names of the 16 HPV Challenge Program orphan chemicals being removed from the Priority Testing List are listed in Table 2 of this unit. Also listed in Table 2 of this unit are the ITC reports in which the HPV Challenge Program orphan chemicals were added to the Priority Testing List and the rationale for their removal. The Universal Resource Locators (URLs or Web site addresses) provide additional information about the disposition of these chemicals and are included as footnotes to Table 2 of this unit.

Fourteen of the HPV Challenge Program orphan chemicals that were removed from the Priority Testing List in this 71st ITC Report were added to the Priority Testing List in the 55th ITC Report (Ref. 1). Two of the HPV Challenge Program orphan chemicals that were removed from the Priority Testing List in this 71st ITC Report were added to the Priority Testing List in the 56th ITC Report (Ref. 2). Six of the HPV Challenge Program orphan chemicals were removed because they were added to a Notice of Proposed Rulemaking (NPRM) that proposed to require manufacturers and processors of these chemicals to conduct testing for acute toxicity, repeated dose toxicity, developmental and reproductive toxicity, genetic toxicity, ecotoxicity, and environmental fate (Ref. 3). Three of the HPV Challenge Program orphan chemicals were removed because they were in the Organization for Economic Cooperation and Development (OECD) Screening Information Data Set (SIDS) program ( http://www.epa.gov/opptintr/ chemtest/pubs/oecdsids.html ). The URLs for the three OECD SIDS chemicals are provided as footnotes b, e, and i to Table 2 of this unit. Six of the HPV Challenge Program orphan chemicals were removed because their testing was sponsored by the chemical’s producers. The URLs for the six sponsored chemicals are provided as footnotes c, d, f, and g to Table 2 of this unit. One chemical was removed because it was an analog to a chemical with robust summaries and test plans. The URL for that chemical is provided as footnote h to Table 2 of this unit.
