Agency for Toxic Substances and Disease Registry March 2008 – Federal Register Recent Federal Regulation Documents

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA or Superfund), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), requires that ATSDR and the Environmental Protection Agency(EPA) prepare a Priority List of Hazardous Substances commonly found at facilities on the CERCLA National Priority List (NPL). The Priority List of Hazardous Substances includes substances that have been determined to be of greatest public health concern to persons at or near NPL sites. CERCLA as amended also requires that ATSDR and EPA periodically revise the Priority List of Hazardous Substances. Pursuant to these CERCLA mandates, the agencies announce that based on the most recent information available, they have developed and now make available a revised CERCLA Priority List of 275 Hazardous Substances. Because CERCLA as amended also requires ATSDR to prepare and to periodically revise toxicological profiles on hazardous substances included in the priority list, each priority list substance is a potential toxicological profile subject, as well as a candidate for identification of priority data needs. In addition to the Priority List of Hazardous Substances, ATSDR has developed a Completed Exposure Pathway Site Count Report. This report lists the number of sites or events at which ATSDR is involved and wherein a substance has been found in a completed exposure pathway (CEP). This report is included in the Support Document of the Priority List.
