SUPPLEMENTARY INFORMATION: The Superfund Amendments and Reauthorization 
Act of 1986 (42 U.S.C. 9601 et seq.) amended the Comprehensive 
Environmental Response, Compensation, and Liability Act of 1980 
(CERCLA) (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. 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 (http://www.atsdr.cdc.gov/cercla/07list.html). 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 March 6, 2008 (73 
FR 12178). 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); and December 7, 
2005 (70FR 70284).
    Notice of the availability of drafts of one updated and one new 
toxicological profile for public review and comment will be published 
in the Federal Register on or about October 17, 2010, 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-

will be incorporated into each profile.
