II. Background

A. What Action is the Agency Taking?

    This list of 371 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 
several years. The list has been assembled from the individual lists of 
chemicals nominated by NAC/AEGL member organizations for AEGL 
development. Although the 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 per year in the 
AEGL development process. There are 137 chemicals on this list of 371 
priority chemicals that are considered a higher priority (indicated by 
an asterisk below), based on considerations of toxicity, volatility, 
presence on numerous organization chemical lists, and other factors. 
These chemicals are planned to be addressed prior to the other listed 
chemicals. Any suggested additions to this priority list and the 
rationale for their addition may be addressed to the Designated Federal 
Officer. An initial listing of 85 priority chemicals was published in 
the Federal Register of May 21, 1997 (62 FR 27733) (FRL-5713-7), to 
facilitate participation by the public in the AEGL process.
    It is believed that publication of today's list of chemicals will 
provide individuals and organizations with

[[Page 38108]]

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.
