SUPPLEMENTARY INFORMATION: The Superfund Amendments and Reauthorization Act (SARA) (Pub. L. 99-499) amends the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) (42 U.S.C. 9601 
                    *et seq.*) by establishing certain statutory requirements for ATSDR and the U.S. Environmental Protection Agency (USEPA) regarding hazardous substances most commonly found at facilities on the National Priorities List (NPL). Among the 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 list identifies 275 hazardous substances that ATSDR and U.S. 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 March 6, 2008 (73 FR 12178). For previous versions of the list of substances, see
