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

[[Page 33529]]

delivery/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. If you wish to submit CBI or information that is 
otherwise protected by statute, please follow the instructions in Unit 
I.D. Do not use EPA Dockets or e-mail to submit CBI or information 
protected by statute.
    1. Electronically. If you submit an electronic comment as 
prescribed in this unit, EPA recommends that you include your name, 
mailing address, and an e-mail address or other contact information in 
the body of your comment. Also include this contact information on the 
outside of any disk or CD ROM you submit, and in any cover letter 
accompanying the disk or CD ROM. This ensures that you can be 
identified as the submitter of the comment and allows EPA to contact 
you in case EPA cannot read your comment due to technical difficulties 
or needs further information on the substance of your comment. EPA's 
policy is that EPA will not edit your comment, and any identifying or 
contact information provided in the body of a comment will be included 
as part of the comment that is placed in the official public docket, 
and made available in EPA's electronic public docket. If EPA cannot 
read your comment due to technical difficulties and cannot contact you 
for clarification, EPA may not be able to consider your comment.
    i. EPA Dockets. Your use of EPA's electronic public docket to 
submit comments to EPA electronically is EPA's preferred method for 
receiving comments. Go directly to EPA Dockets at http://www.epa.gov/edocket/, and follow e online instructions for submitting comments. 
Once in the system, select ``search,'' and then key in docket ID number 
OPPT-2004-0090. The system is an ``anonymous access'' system, which 
means EPA will not know your identity, e-mail address, or other contact 
information unless you provide it in the body of your comment.
    ii. E-mail. Comments may be sent by e-mail to [email protected], 
Attention: Docket ID Number OPPT-2004-0090. In contrast to EPA's 
electronic public docket, EPA's e-mail system is not an ``anonymous 
access'' system. If you send an e-mail comment directly to the docket 
without going through EPA's electronic public docket, EPA's e-mail 
system automatically captures your e-mail address. E-mail addresses 
that are automatically captured by EPA's e-mail system are included as 
part of the comment that is placed in the official public docket, and 
made available in EPA's electronic public docket.
    iii. Disk or CD ROM. You may submit comments on a disk or CD ROM 
that you mail to the mailing address identified in Unit I.C.2. These 
electronic submissions will be accepted in WordPerfect or ASCII file 
format. Avoid the use of special characters and any form of encryption.
    2. By mail. Send your comments to: Document Control Office (7407M), 
Office of Pollution Prevention and Toxics (OPPT), Environmental 
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-

Friday, excluding legal holidays. The telephone number for the DCO is 
(202) 564-8930.

D. How Should I Submit CBI to the Agency?

    Do not submit information that you consider to be CBI 
electronically through EPA's electronic public docket or by e-mail. You 
may claim information that you submit to EPA as CBI by marking any part 
or all of that information as CBI (if you submit CBI on disk or CD ROM, 
mark the outside of the disk or CD ROM as CBI and then identify 
electronically within the disk or CD ROM the specific information that 
is CBI). Information so marked will not be disclosed except in 
accordance with procedures set forth in 40 CFR part 2.
    In addition to one complete version of the comment that includes 
any information claimed as CBI, a copy of the comment that does not 
contain the information claimed as CBI must be submitted for inclusion 
in the public docket and EPA's electronic public docket. If you submit 
the copy that does not contain CBI on disk or CD ROM, mark the outside 
of the disk or CD ROM clearly that it does not contain CBI. Information 
not marked as CBI will be included in the public docket and EPA's 
electronic public docket without prior notice. If you have any 
questions about CBI or the procedures for claiming CBI, please consult 
the technical person listed under FOR FURTHER INFORMATION CONTACT.

E. What Should I Consider as I Prepare My Comments for EPA?

    We invite you to provide your views and comments on the ITC 54\th\ 
Report. You may find the following suggestions helpful for preparing 
your comments:
    1. Explain your views as clearly as possible.
    2. Describe any assumptions that you used.
    3. Provide copies of any technical information and/or data you used 
that support your views.
    4. Provide specific examples to illustrate your concerns.
    5. Make sure to submit your comments by the deadline in this 
notice.
    6. To ensure proper receipt by EPA, be sure to identify the docket 
ID number assigned to this action in the subject line on the first page 
of your response. You may also provide the name, date, and Federal 
Register citation.

II. Background

    The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601et 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.

A. The ITC's 54\th\ Report

    The 54\th\ ITC Report was transmitted to the EPA's Administrator on 
April 23, 2004, and is included in this notice. In the 54\th\ ITC 
Report, the ITC is revising the Priority Testing List by removing 25 
vanadium compounds. In addition, the ITC is soliciting public comments 
on the idea of posting on the ITC's web site, broad non-CBI categories 
of worker numbers and worker hours created from TSCA section 8(a) PAIR 
rule submissions.

B. Status of the Priority Testing List

    The current TSCA 4(e) Priority Testing List as of April 2004 can be 
found in Table 1 of the 54\th\ ITC Report, which is included in this 
notice.

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 
...

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

[[Page 33531]]

within 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 53\rd\ 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) (42\nd\ ITC Report, 
Ref. 3), 9 indium compounds (47\th\ ITC Report, Ref. 4); benzenamine, 
3-chloro-2, 6-dinitro-N,N-dipropyl-4-(trifluoromethyl)- (CAS No. 29091-
20-1) (48\th\ ITC Report, Ref. 5); and stannane, dimethylbis[(1-
oxoneodecyl)oxy]- (CAS No. 68928-76-7) (49\th\ 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) (50\th\ ITC Report, Ref. 7). 
The TSCA section 8(d) studies requested for these chemicals were listed 
in the ITC's 51\st\ 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, 45\th\ 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 45\th\ 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 54\th\ 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 51\st\ 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.
