SUPPLEMENTARY INFORMATION: The U.S. Environmental Protection Agency is 
undertaking a reassessment of the health risk of 1,3-butadiene to 
support decision making regarding the Air Toxic Rule's Section 
202(l)(2) of the Clean Air Act Amendments. This assessment focuses on 
mutagenicity, carcinogenicity, and reproductive/developmental effects, 
and is not intended to be a comprehensive health assessment. The 
exposure information included in this document is an overview of the 
ambient exposure and exposure to populations adjacent to emission 
sources, without any actual exposure assessment as such.
    The draft document also will undergo review by the Agency's Science 
Advisory Board (SAB) at a public meeting to be held in Washington, DC, 
in May of 1998. Specific details about that meeting will be announced 
in a later Federal Register document. Interested parties will be 
afforded an opportunity to present brief oral comments on the draft at 
the meeting.

    Dated: February 5, 1998.

Director, National Center for Environmental Assessment.
