v. If you estimate potential costs or burdens, explain how you arrived at


## 65487 Federal Register / Vol. 73, No. 213 / Monday, November 3, 2008 / Notices

your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified. II. Background

The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq .) authorizes the Administrator of the 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.

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, 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) Health and Safety Data Reporting (HaSDR) rules. 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 ). 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.


## 65488 Federal Register / Vol. 73, No. 213 / Monday, November 3, 2008 / Notices

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 ( http://www.epa.gov/opptintr/itc).
III. ITC’s Activities During this Reporting Period (June to October 2008)

During this reporting period, the ITC discussed tungsten compounds and HPV Challenge Program orphan chemicals.
IV. Revisions to the TSCA Section 4(e) Priority Testing List: Chemicals Removed From the Priority Testing List
A. Tungsten Compounds

Of the 22 tungsten compounds added to the Priority Testing List in the 53 rd ITC Report (Ref. 1) and the 56 th ITC Report (Ref. 2), 12 were removed in the 58 th ITC Report (Ref. 3), 5 were removed in the 59 th ITC Report (Ref. 4), and 4 were removed in the
62 nd ITC Report (Ref. 5). At this time the ITC is removing tungstate (WO 4 2- ), disodium, dihydrate, (T-4)-, a.k.a. disodium tungstate (Na 2WO 4 ) dihydrate (CAS No. 10213–10–2) from the Priority Testing List because of the voluntary information provided by the International Tungsten Industry Association and their cooperation in a National Toxicology Program/National Institute for Occupational Safety and Health research program to address exposure and toxicity data needs.
B. HPV Challenge Program Orphan Chemicals

270 HPV Challenge Program orphan chemicals were added to the Priority Testing List in the 55 th ITC Report (Ref. 6) and 5 were added to the Priority Testing List in the 56 th ITC Report (Ref. 2).

30 HPV Challenge Program orphan chemicals were removed from the Priority Testing List in the 56 th ITC Report (Ref. 2). The HPV Challenge Program orphan chemicals that were removed in the 56 th ITC Report included ethanol, 2-methoxy- (CAS No. 109–86–4) and tetradecane (CAS No. 629–59–4) that were on the Priority Testing List when the 55 th ITC Report was sent to the EPA Administrator on December 8, 2004, but removed from Priority Testing List before the
55 th ITC Report was published in the Federal Register because sponsorship of these 2 substances was transferred to the International Council of Chemical Associations HPV Initiative. The HPV Challenge Program orphan chemicals that were removed in the 56 th ITC Report also included 11 chemicals that were sponsored before the 55 th ITC Report was sent to the EPA Administrator on December 8, 2004 (see Table 6 in the 56 th ITC Report) and 17 chemicals that no longer meet the HPV criterion (see Table 7 in the 56 th ITC Report).

8 HPV Challenge Program orphan chemicals were removed from the Priority Testing List in the 58 th ITC Report (Ref. 3) (see Table 2 in the 58 th ITC Report). These 8 chemicals included 4 that were on the Priority Testing List when the 55 th ITC Report was sent to the EPA Administrator on December 8, 2004, but removed from Priority Testing List before the 55 th ITC Report was published in the Federal Register . These 4 chemicals were retained on the December 8,
2004 Priority Testing List because sponsorship commitments were received by EPA after December 8, 2004. These 4 chemicals are phosphoric acid, tris(2- ethylhexyl) ester (CAS No. 78–42–2); phosphoric acid, 2-ethylhexyl ester (CAS No. 12645–31–7); 1-propanamine, 3- (tridecyloxy)-, branched (CAS No. 68511–40– 0); and hydrocarbons, C 8– 11 (CAS No. 68553– 14–0).

35 HPV Challenge Program orphan chemicals were removed from the Priority Testing List in the 61 st ITC Report (Ref. 7) (see Table 4 in the 61 st ITC Report). These 35 chemicals included 1,3-propanediol, 2- amino-2-(hydroxymethyl)- (CAS No. 77–86– 1) that was added to the Priority Testing List in the 56 th ITC Report (Ref. 2).

In this 63 rd ITC Report, disulfides, C 5– 12 - alkyl (CAS No. 68513–62–2) are being removed from the Priority Testing List because they no longer meet the HPV criterion. Disulfides, C 5– 12 -alkyl were added to the Priority Testing List in the 55 th ITC Report (Ref. 6).
