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 the U.S. Environmental Protection Agency 
(EPA) with regard to hazardous substances that are most commonly found 
at facilities on the CERCLA National Priorities List (NPL). Among these 
statutory requirements is a mandate for the Administrator of ATSDR to 
prepare toxicological profiles for each substance included on the 
priority lists of hazardous substances. These lists identified 275 
hazardous substances that ATSDR and EPA determined 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 prior versions of 
the list of substances, see Federal Register notices dated April 17, 
1987 (52 FR 12866); October 20, 1988 (53 FR 41280); October 26, 1989

52166); October 28, 1992 (57 FR 48801); February 28, 1994 (59 FR 9486);
