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 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
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 19
hazardous substances. These AEGLs represent the 12\th\ set of exposure
levels proposed and published by the NAC/AEGL Committee. These 12 sets
of AEGLs cover 259 hazardous substances. Background information on the
AEGL Program may be found in these earlier Federal Register notices, in
the regulations.gov, or on the AEGL
[[Page 41898]]
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 Committees 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, it
is intended to have them reviewed by a subcommittee of the National
Academies (NAS). The NAS subcommittee 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 19
hazardous substances identified in the table in this unit. Technical
Support Documents are available in the docket for this notice. See
