SUPPLEMENTARY INFORMATION: The Superfund Amendments and Reauthorization 
Act (SARA) of 1986 (Pub. L. 99-499) amended the Comprehensive 
Environmental Response, Compensation, and Liability Act (CERCLA or 
Superfund). Section 211 of SARA also amended Title 10 of the U.S. Code, 
creating the Defense Environmental Restoration Program. Section 2704 of 
Title 10 of the U.S. Code directs the Secretary of Defense to notify 
the Secretary of Health and Human Services (HHS) of not less than 25 of 
the most commonly found unregulated hazardous substances at defense 
facilities. The Secretary of HHS is to prepare toxicological profiles 
of these substances. Each profile is to include an examination, summary 
and interpretation of available toxicological information and 
epidemiologic evaluations. This information is used to ascertain the 
level of significant human exposure for the substance and the 
associated health effects. The toxicological profile includes a 
determination of whether adequate information on the health effects of 
each substance is available or in the process of development. When 
adequate information is not available, ATSDR, in cooperation with the 
National Toxicology Program (NTP), may plan a program of research 
designed to determine these health effects.
    Notice of the availability of the draft profile for public review 
and comment was published in the Federal Register on August 26, 2010, 
(75 FR 52535), with notice of a 90-day public comment period starting 
from the actual release date. Following the close of the comment 
period, chemical-specific comments were addressed, and, where 
appropriate, changes were incorporated into each profile. The public 
comments and other data submitted in response to the Federal Register 
notice bears the docket control number ATSDR-266. This material is

Disease Registry, 4700 Buford Highway, Building 106, Second Floor,
