SUPPLEMENTARY INFORMATION:

The Superfund Amendments and Reauthorization Act (SARA) (Pub. L. 99-499) amended the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) (42 U.S.C. 9601

et seq.

) by establishing certain requirements for ATSDR and the Environmental Protection Agency (EPA) regarding hazardous substances which are most commonly found at facilities on the 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 most hazardous substances was announced in the

Federal Register
