SUPPLEMENTAL INFORMATION

The Superfund Amendments and Reauthorization Act (SARA) (Pub. L. 99499) amends 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 U.S. Environmental Protection Agency (EPA) concerning 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. ATSDR and EPA identified 275 hazardous substances that 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 November 7, 2003 (68 FR 63098). 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 (54 FR 43619); October 17, 1990 (55 FR 42067); October 17, 1991 (56 FR 52166); October 28, 1992 (57 FR 48801); February 28, 1994 (59 FR 9486); April 29, 1996 (61 FR 18744); November 17, 1997 (62 FR 61332); October 21, 1999 (64 FR 56792); and October 25, 2001 (66 FR 54014).
