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 available for public inspection at the Agency for Toxic Substances and Disease Registry, 4700 Buford Highway, Building 106, Second Floor, Chamblee, Georgia 30341 between 8 a.m. and 4:30 p.m., Monday through Friday, except legal holidays.
