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.

[[Page 65488]]

    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listed chemicals to submit to EPA copies and lists of unpublished 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 (WO4\2\-), disodium, dihydrate, (T-
4)-, a.k.a. disodium tungstate (Na2WO4) 
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, C8-11 (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, C5-
12-alkyl (CAS No. 68513-62-2) are being removed from the 
Priority Testing List because they no longer meet the HPV criterion. 
Disulfides, C5-12-alkyl were added to the 
Priority Testing List in the 55\th\ ITC Report (Ref. 6).
