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?
EPA’s Office of Prevention, Pesticides and Toxic Substances (OPPTS) provided notice in the Federal Register of 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 AEGL values for hazardous 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 62 hazardous chemicals. These AEGL values represent the 11th set of exposure levels proposed and published by the NAC/AEGL Committee. These 11 sets of AEGL values cover 239 hazardous chemicals. Background information on the AEGL Program may be found in the earlier Federal Register notices available in regulations.gov or on the AEGL website (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 AEGL values. Although the interim AEGL values 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 AEGL values and as the final arbiter in the resolution of issues regarding the AEGL values, and the data and basic methodology used for setting AEGL values. Following concurrence, final AEGL values will be published under the auspices of NAS.
