Proposed Acute Exposure Guideline Levels for Hazardous
Substances; 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 substances. This
notice provides a list of 13 proposed AEGLs that are available for
public review and comment. Comments are welcome on both the proposed
AEGLs and their Technical Support Documents placed in the docket.
DATES: Comments must be received on or before August 27, 2010.

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 website is an ``anonymous access'' system,

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.
Docket: All documents in the docket are listed in the docket index
available at http://www.regulations.gov. 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. The OPPT Docket is located in the EPA
Docket Center (EPA/DC) at Rm. 3334, EPA West Bldg., 1301 Constitution
Ave., NW., Washington, DC. The EPA/DC Public Reading Room hours of
operation are 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. Docket visitors are required to show photographic

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 AEGLs and their
Technical Support Documents. This action may be of particular interest
to anyone who may be affected if the AEGLs 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 AEGLs 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
[[Page 44250]]
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?
EPA's Office of Prevention, Pesticides and Toxic Substances
(OPPTS), renamed the Office of Chemical Safety and Pollution Prevention
(OCSPP), as of April 22, 2010, 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 hazardous substances 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 AEGLs and underlying supporting documents for 13
hazardous substances. These AEGLs represent the 13\th\ set of exposure
levels proposed and published by the NAC/AEGL Committee. These 13 sets
of AEGLs cover 261 hazardous substances. Background information on the
AEGL Program may be found in these earlier Federal Register notices, on
regulations.gov, or the AEGL webpage (http://www.epa.gov/oppt/aegl).
Following public review and comment, the NAC/AEGL Committee will
reconvene to consider relevant comments, data, and information that may
have an impact on the NAC/AEGL Committee's position and will again seek
consensus for the establishment of Interim AEGLs. Although the Interim
AEGLs will be available to Federal, State, and local agencies and to
organizations in the private sector as biological reference values, a
National Academies subcommittee for AEGLs will serve as a peer review
of the Interim AEGLs and as the final arbiter in the resolution of
issues regarding the AEGLs, and the data and basic methodology used for
setting AEGLs. Following concurrence, Final AEGLs will be published
under the auspices of the NAS.
III. List of Hazardous Substances
On behalf of the NAC/AEGL Committee, EPA is providing an
opportunity for public comment on the proposed AEGLs for the 13
hazardous substances identified in the table in this unit. Technical
Support Documents are available in the docket for this notice. See
