SUPPLEMENTARY INFORMATION:

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

et seq.

] amended the CERCLA (or Superfund) [42 U.S.C. 9601

et seq.

] by establishing certain requirements for ATSDR and the U.S. Environmental Protection Agency (EPA) with regard to hazardous substances most commonly found at facilities on the CERCLA NPL. Among these statutory requirements is a mandate for the Administrator of ATSDR to prepare toxicological profiles for each substance included on the Priority List of Hazardous Substances. This identifies 275 hazardous substances that ATSDR and EPA have determined pose the most significant potential threat to human health (

http://www.atsdr.cdc.gov/cercla/07list.html

). The availability of the revised list of the 275 priority substances was announced in the

Federal Register

on March 6, 2008 (73 FR 12178). For prior versions of the list of substances, see
