Agency for Toxic Substances and Disease Registry November 2011 – 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 Priorities 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 the Priority List of Hazardous Substances be revised periodically. This announcement provides notice that a revised Priority List of 275 Hazardous Substances has been developed and is now available for download. CERCLA as amended also requires ATSDR to prepare and to periodically revise toxicological profiles on hazardous substances included in the priority list. Thus, 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).
