ENVIRONMENTAL PROTECTION AGENCY
[OPPTS-41047;FRL-5713-7]
National Advisory Committee for Acute Exposure Guideline Levels
for Hazardous Substances; List of Priority Chemicals for Guideline
Development
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of list of priority chemicals.
-----------------------------------------------------------------------
SUMMARY: The National Advisory Committee for Acute Exposure Guideline
Levels for Hazardous Substances (NAC/AEGL), established by EPA under
the Federal Advisory Committee Act (FACA), develops AEGLs on an ongoing
basis to assist with Federal, State, and other organization needs for
short-term hazardous chemical exposure information. An initial listing
of 85 priority chemicals is provided in this notice to facilitate
participation by the public in the AEGL process. Sixteen (16) of these
priority chemicals have already been addressed by the NAC/AEGL (as
noted in the table) and it is anticipated that proposed AEGL values and
accompanying rationale for approximately 13 chemicals will be published
in the Federal Register for comment within the next several months.
NAC/AEGL encourages the submission of acute toxicology data or other
pertinent information on these chemicals and all other chemicals on the
list to the Designated Federal Officer, see ``FOR FURTHER INFORMATION
CONTACT''.
ADDRESSES: Submit three copies of the data or other pertinent
information identified by the docket control number [OPPTS-41047] to:
TSCA Document Control Office (7407), Office of Pollution Prevention and
Toxics, Environmental Protection Agency, Room ET-G99, 401 M St., SW.,
Washington, DC 20460 and one copy to the Designated Federal Officer in
``FOR FURTHER INFORMATION CONTACT''.
A public version of this record, which does not include any
information claimed as Confidential Business Information (CBI), is
available for inspection from 12 noon to 4 p.m., Monday through Friday,
excluding legal holidays. The public record is located in TSCA Dockets,
Room NEB-607, Environmental Protection Agency, 401 M St., SW.,
Washington, DC.
FOR FURTHER INFORMATION CONTACT: Paul S. Tobin, Designated Federal
Officer, Office of Prevention, Pesticides, and Toxic Substances (7406),
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460.
Location, phone number, and e-mail address: Room 349A, East Tower,
Environmental Protection Agency, 401 M St., SW., Washington, DC, 202-
260-1736, e-mail: tobin.paul@epamail.epa.gov.
SUPPLEMENTARY INFORMATION: The list of 85 priority chemicals is a
composite of numerous priority lists of acutely toxic chemicals and
represents the selection of chemicals for AEGL development by the NAC/
AEGL during the next 2 to 3 years. The list has been assembled from the
individual lists of chemicals nominated by NAC/AEGL member
organizations for AEGL development. Although this priority list of
chemicals, published in this notice, is subject to modification as
priorities of the NAC/AEGL committee or the NAC/AEGL member
organizations change, it is anticipated that most of the chemicals on
the priority list will remain as high priority for AEGL development
during the next several years. The NAC/AEGL intends to address at least
30 chemicals
[[Page 27734]]
per year in the AEGL development process and, therefore, this list of
chemicals will be expanded as the NAC/AEGL continues to focus on
chemicals of interest to its member organizations. Any suggested
additions to this initial priority list and the rationale for their
addition may be addressed to the Designated Federal Officer.
It is believed that publication of this initial list of chemicals
will provide individuals and organizations with ample time to gather
existing data and information and, where appropriate, to develop new
data and information on the acute toxicity of the chemicals listed
herein, for the consideration of the NAC/AEGL. Parties possessing such
data and information or those anticipating the future conduct of
toxicity studies on any of these chemicals should contact the
Designated Federal Officer.
