Certain types of information will not be placed in the EPA Dockets. Information claimed as CBI and other information whose disclosure is restricted by statute, which is not included in the official public docket, will not be available for public viewing in EPA's electronic public docket. EPA's policy is that copyrighted material will not be placed in EPA's electronic public docket but will be available only in printed, paper form in the official public docket. To the extent feasible, publicly available docket materials will be made available in EPA's electronic public docket. When a document is selected from the index list in EPA Dockets, the system will identify whether the document is available for viewing in EPA's electronic public docket. Although not all docket materials may be available electronically, you may still access any of the publicly available docket materials through the docket facility identified in Unit I.B.1. EPA intends to work towards providing electronic access to all of the publicly available docket materials through EPA's electronic public docket.

For public commenters, it is important to note that EPA's policy is that public comments, whether submitted electronically or in paper, will be made available for public viewing in EPA's electronic public docket as EPA receives them and without change, unless the comment contains copyrighted material, CBI, or other information whose disclosure is restricted by statute. When EPA identifies a comment containing copyrighted material, EPA will provide a reference to that material in the version of the comment that is placed in EPA's electronic public docket. The entire printed comment, including the copyrighted material, will be available in the public docket.

Public comments submitted on computer disks that are mailed or delivered to the docket will be transferred to EPA's electronic public docket. Public comments that are mailed or delivered to the docket will be scanned and placed in EPA's electronic public docket. Where practical, physical objects will be photographed, and the photograph will be placed in EPA's electronic public docket along with a brief description written by the docket staff.

C. How and to Whom Do I Submit Comments?

You may submit comments electronically, by mail, or through hand Start Printed Page 33529delivery/courier. To ensure proper receipt by EPA, identify the appropriate docket ID number in the subject line on the first page of your comment. Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

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 web site (http://www.epa.gov/​opptintr/​itc/​) within a few days of submission to the Administrator and from the EPA's web site 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 U.S. EPA's Office of Pollution Prevention and Toxics (OPPT) adds the chemicals from the revised Priority Testing List to the TSCA section 8(a) PAIR and TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rules. The PAIR rule requires producers and importers of Chemical Abstract Service (CAS)-numbered chemicals added to the Priority Testing List to submit production and exposure reports (http://www.epa.gov/​opptintr/​chemtest/​pairform.pdf/​). The HaSDR rule requires producers, importers, and processors of all chemicals added to the Priority Testing List to submit unpublished health and safety studies under TSCA section 8(d) that must be in compliance with the revised HaSDR rule (Ref. 1). All submissions must be received by EPA Start Printed Page 33531within 90 days of the reporting rules Federal Register publication date.

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 previous ITC reports (http://www. epa.gov/opptintr/itc/rptmain.htm/).

C. Previous Requests to Add Chemicals to the TSCA Section 8(a) PAIR Rule

In its 53rd ITC Report, the ITC requested that EPA add 3 pyridinamines and 20 tungsten compounds to the TSCA section 8(a) PAIR rule (Ref. 2).

D. Previous Requests to Add Chemicals to the TSCA Section 8(d) HaSDR Rule

In previous ITC reports it was requested that the following chemicals be added to the TSCA section 8(d) HaSDR rule: 3H-1,2,4-triazole-3-thione, 5-amino-1,2-dihydro- (3-amino-5-mercapto-1,2,4-triazole) (CAS No. 16691-43-3) and imidazo[4,5-d]imidazole-2,5(1H,3H)-dione, tetrahydro- (glycoluril) (CAS No. 496-46-8) (42nd ITC Report, Ref. 3), 9 indium compounds (47th ITC Report, Ref. 4); benzenamine, 3-chloro-2, 6-dinitro-N,N-dipropyl-4-(trifluoromethyl)- (CAS No. 29091-20-1) (48th ITC Report, Ref. 5); and stannane, dimethylbis[(1-oxoneodecyl)oxy]- (CAS No. 68928-76-7) (49th ITC Report, Ref. 6); benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5) and 1-triazene, 1,3-diphenyl- (CAS No.136-35-6) (50th ITC Report, Ref. 7). The TSCA section 8(d) studies requested for these chemicals were listed in the ITC's 51st Report (Ref. 8). On May 4, 2004, EPA issued a final rule pursuant to TSCA section 8(d) requiring manufacturers (including importers) of these 15 chemicals to report certain unpublished health and safety data to EPA (Ref. 9).

III. ITC's Activities During this Reporting Period (November 2003 to April 2004)

During this reporting period, the ITC received voluntary submissions of exposure-related information on vanadium compounds. The ITC acknowledges and appreciates the submissions received from BASF Corporation; Cormetech, Inc.; Engelhard Corporation; OSRAM Sylvania, Inc.; W.R. Grace & Company; Color Pigments Manufacturers Association; Sud Chemie; Akzo Nobel Chemicals, Inc.; American Acryl L.P. International, Inc.; and the Vanadium Producers and Reclaimers Association (VPRA). The procedures for submitting voluntary information through the ITC's Voluntary Information Submissions Innovative Online Network (VISION) are described on the ITC's web site (http://www.epa.gov/​opptintr/​itc/​vision.htm/​).

During this reporting period, the ITC reviewed the CBI PAIR reports submitted in response to the June 11, 2003, PAIR rule (Ref. 10). The ITC is exploring the idea of sanitizing the CBI data to create broad non-CBI categories of worker numbers and worker hours that it could share with the public. To accomplish this, the ITC is proposing the idea of posting these broad non-CBI categories of worker numbers and worker hours on the ITC's web site (http://www.epa.gov/​opptintr/​itc/​).

There is a precedent for the ITC to do this. In its November 30, 1999, 45th ITC Report to the EPA Administrator (Ref. 11), the ITC discussed the idea of sharing non-CBI production volume ranges with the public. In May 2001, the EPA posted on its web site non-CBI production volume ranges for chemicals that were reported in response to the 1998 Inventory Update Rule (IUR) (http://www.epa.gov/​oppt/​iur/​iur98/​index.htm/​). Since then, these ranges have been revised and the non-CBI production volume ranges for chemicals that were reported in response to the 1986, 1990, 1994, and 2002 IUR have been posted on EPA's web site (http://www.epa.gov/​oppt/​iur/​iur02/​index.htm/​ ).

By making broad non-CBI categories of worker numbers and worker hours available to the public, the ITC is suggesting that this information could be used to make more recent occupational-exposure estimates then provided by the 1981-1983 NIOSH National Occupational Exposure Survey. The ITC is proposing posting the following broad non-CBI categories on its web site:

Worker ranges: <100;100-1,000; 1,000-10,000; and >10,000.

Worker hour ranges: <100, 100-1,000; 1,000-10,000; and >10,000.

Comments on these proposals should be sent to the ITC Director by July 15, 2004.

IV. Revisions to the TSCA Section 4(e) Priority Testing List

In its 45th ITC Report (Ref. 11), the ITC removed 47 chemicals from the Priority Testing List, because EPA published a June 9, 1999, Federal Register notice proposing in vitro dermal absorption rate testing for these chemicals (Ref. 12). In its June 9, 1999, Federal Register notice, the EPA also mentioned that in vitro dermal absorption rate testing did not have to be conducted for tert-butyl alcohol (CAS No. 75-65-0) because an in vivo study of its dermal absorption rate was submitted to the EPA in 1998. The ITC is removing tert-butyl alcohol from the Priority Testing List in this 54th ITC Report because the EPA found that the 1998 in vivo study was sufficiently adequate not to require in vitro dermal absorption rate testing of tert-butyl alcohol. On April 26, 2004, EPA issued a final rule pursuant to TSCA section 4(a) requiring manufacturers (including importers) to conduct in vitro dermal absorption rate testing for 34 of these chemicals (Ref. 13).

Forty-three vanadium compounds were added to the Priority Testing List in the ITC's 51st Report (Ref. 8). Based on responses to the June 11, PAIR rule (Ref. 10), the ITC is removing 25 vanadium compounds from the Priority Testing List (Table 2). The 18 vanadium compounds remaining on the Priority Testing List are listed in Table 3.
