Agency for Toxic Substances and Disease Registry December 7, 2005 – Federal Register Recent Federal Regulation Documents

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund), as amended by the Superfund Amendments and Reauthorization Act (SARA), requires that ATSDR and the Environmental Protection Agency (EPA) revise the Priority List of Hazardous Substances. This list includes substances most commonly found at facilities on the CERCLA National Priorities List (NPL) which have been determined to be of greatest concern to public health at or around these NPL hazardous waste sites. This announcement provides notice that the agencies have developed and are making available a revised CERCLA Priority List of 275 Hazardous Substances, based on the most recent information available. Each substance on the priority list is a candidate to become the subject of a toxicological profile prepared by ATSDR and subsequently a candidate for the 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 with ATSDR activities where a substance has been found in a completed exposure pathway (CEP). This report is included in the Support Document of the Priority List.
