SUPPLEMENTARY INFORMATION:

The Superfund Amendments and Reauthorization Act of 1986 (SARA) (42 U.S.C. 9601

et seq.

) amended the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA or Superfund) (42 U.S.C. 9601

et seq.

) by establishing certain requirements for ATSDR and for the U.S. Environmental Protection Agency (EPA) with regard to hazardous substances most commonly found at facilities on the CERCLA National Priorities List (NPL). One such requirement directs the ATSDR Administrator to prepare toxicological profiles for each substance included on the priority lists of hazardous substances. These lists identify 275 hazardous substances determined by ATSDR and by EPA to pose the most significant potential threat to human health. The availability of the revised list of the 275 priority substances was announced in the

Federal Register

on December 7, 2005 (70 FR 234). For previous versions of the list of substances, see
