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 List of Hazardous Substances (www.atsdr.cdc.gov/SPL). This 
list names 275 hazardous substances that pose the most significant 
potential threat to human health as determined by ATSDR and EPA. The 
availability of the revised list of the 275 priority substances was 
announced in the Federal Register on November 3, 2011 (76 FR 68193). 
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); October 25, 
2001 (66 FR 54014); November 7, 2003 (68 FR 63098); December 7, 2005 
(70 FR 70284); and March 6, 2008 (73 FR 12178).
    Notice of the availability of drafts of these four updated 
toxicological profiles for public review and comment will be published 
in the Federal Register on or about October 17, 2012, with notice of a 
90-day public comment period for each profile, starting from the actual 
release date. Following the close of the comment period, chemical-
specific comments will be addressed, and, where appropriate, changes 
will be incorporated into each profile.
