ENVIRONMENTAL PROTECTION AGENCY
[EPA-HQ-OPPT-2004-0128; FRL-8095-1]
National Advisory Committee for Acute Exposure Guideline Levels
(AEGLs) for Hazardous Substances; Proposed AEGL Values; Notice of
Availability
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The National Advisory Committee for Acute Exposure Guideline
Levels for Hazardous Substances (NAC/AEGL Committee) is developing
AEGLs on an ongoing basis to provide Federal, State, and local agencies
with information on short-term exposures to hazardous chemicals. This
notice provides a list of 46 proposed AEGL chemicals that are available
for public review and comment. Comments are welcome on both the AEGL
values and the technical support documents placed in the docket.
DATES: Comments must be received on or before November 13, 2006.
ADDRESSES: Submit your comments, identified by docket identification
(ID) number EPA-HQ-OPPT-2004-0128, by one of the following methods:
Federal eRulemaking Portal: http://www.regulations.gov.
Follow the on-line instructions for submitting comments.
Mail: Document Control Office (7407M), Office of Pollution
Prevention and Toxics (OPPT), Environmental Protection Agency, 1200
Pennsylvania Ave., NW., Washington, DC 20460-0001.

included in the docket without change and may be made available on-line
at http://www.regulations.gov, including any personal information
provided, unless the comment includes information claimed to be
Confidential Business Information (CBI) or other information whose
disclosure is restricted by statute. Do not submit information that you
consider to be CBI or otherwise protected through regulations.gov or e-
mail. The regulations.gov Web site is an ``anonymous access'' system,
which means EPA will not know your identity or contact information
unless you provide it in the body of your comment. If you send an e-
mail comment directly to EPA without going through regulations.gov,
your e-mail address will be automatically captured and included as part
of the comment that is placed in the docket and made available on the
Internet. If you submit an electronic comment, EPA recommends that you
include your name and other contact information in the body of your
comment and with any disk or CD-ROM you submit. 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. Electronic
files should avoid the use of special characters, any form of
encryption, and be free of any defects or viruses. For additional
information about EPA's public docket, visit the EPA Docket Center
homepage at http://www.epa.gov/epahome/dockets.htm.
Docket: All documents in the docket are listed in the
regulations.gov index. Although listed in the index, some information
is not publicly available, e.g., CBI or other information whose
disclosure is restricted by statute. Certain other material, such as
copyrighted material, will be publicly available only in hard copy.
Publicly available docket materials are available electronically at
http://www.regulations.gov, or, if only available in hard copy, at the
OPPT Docket, EPA Docket Center (EPA/DC). The EPA/DC suffered structural
damage due to flooding in June 2006. Although the EPA/DC is continuing
operations, there will be temporary changes to the EPA/DC during the
clean-up. The EPA/DC Public Reading Room, which was temporarily closed
due to flooding, has been relocated in the EPA Headquarters Library,
Infoterra Room (Room Number 3334) in EPA West, located at 1301
Constitution Ave., NW., Washington, DC. The EPA/DC Public Reading Room
[[Page 60142]]
is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding
legal holidays. The telephone number of the EPA/DC Public Reading Room
is (202) 566-1744, and the telephone number for the OPPT Docket is
(202) 566-0280. EPA visitors are required to show photographic
identification and sign the EPA visitor log. Visitors to the EPA/DC
Public Reading Room will be provided with an EPA/DC badge that must be
visible at all times while in the EPA Building and returned to the
guard upon departure. In addition, security personnel will escort
visitors to and from the new EPA/DC Public Reading Room location. Up-
to-date information about the EPA/DC is on the EPA Web site at http://www.epa.gov/epahome/dockets.htm

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this Action Apply to Me?
This action is directed to the general public to provide an
opportunity for review and comment on proposed AEGL values and their
supporting scientific rationale. This action may be of particular
interest to anyone who may be affected if the AEGL values are adopted
by government agencies for emergency planning, prevention, or response
programs, such as EPAs Risk Management Program under the Clean Air Act
and Amendments Section 112r. It is possible that other Federal agencies
besides EPA, as well as State and local agencies and private
organizations, may adopt the AEGL values for their programs. As such,
the Agency has not attempted to describe all the specific entities that
may be affected by this action. If you have any questions regarding the
applicability of this action to a particular entity, consult the DFO
listed under FOR FURTHER INFORMATION CONTACT.
B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM
that you mail to EPA, 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 claimed as CBI. In addition to one complete version
of the comment that includes 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. Information so marked
will not be disclosed except in accordance with procedures set forth in
40 CFR part 2.
2. Tips for preparing your comments. When submitting comments,
remember to:
i. Identify the document by docket ID number and other identifying
information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at 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. What Action is the Agency Taking?
EPAs Office of Prevention, Pesticides and Toxic Substances (OPPTS)
provided notice on October 31, 1995 (60 FR 55376) (FRL-4987-3) of the
establishment of the NAC/AEGL Committee with the stated charter
objective as ``the efficient and effective development of AEGLs and the
preparation of supplementary qualitative information on the hazardous
substances for Federal, State, and Local agencies and organizations in
the private sector concerned with [chemical] emergency planning,
prevention, and response.'' The NAC/AEGL Committee is a discretionary
Federal advisory committee formed with the intent to develop AEGLs for
chemicals through the combined efforts of stakeholder members from both
the public and private sectors in a cost-effective approach that avoids
duplication of efforts and provides uniform values, while employing the
most scientifically sound methods available.
This action provides notice of availability, for public review and
comment, of proposed AEGL values and underlying supporting documents
for 46 hazardous substances. These values represent the ninth set of
exposure levels proposed and published by the NAC/AEGL Committee. EPA
published the first ``proposed'' AEGLs for 12 chemicals from the
initial priority list in the Federal Register of October 30, 1997 (62
FR 58840-58851) (FRL-5737-3); for 10 chemicals in the Federal Register
of March 15, 2000 (65 FR 14186-14197) (FRL-6492-4); for 14 chemicals in
the Federal Register of June 23, 2000 (65 FR 39263-39277 ) (FRL-6591-
2); for 7 chemicals in the Federal Register of December 13, 2000 (65 FR
77866-77874) (FRL-6752-5); for 18 chemicals in the Federal Register of
May 2, 2001 (66 FR 21940-21964) (FRL-6776-3); for 8 chemicals in the
Federal Register of February 15, 2002 (67 FR 7164-7176) (FRL-6815-8);
for 10 chemicals in the Federal Register of July 18, 2003 (68 FR 42710-
42726) (FRL-7189-8); and for 15 chemicals in the Federal Register of
September 7, 2004 (69 FR 54144-54148) (FRL-7350-2) in order to provide
an opportunity for public review and comment. Background information on
the AEGL Program may be found in these earlier Federal Register
notices, in regulations.gov, or on the AEGL Web site at http://www.epa.gov/oppt/aegl
