List: Extremely Hazardous Substances (Superfund)
Description
The Superfund Amendments and Reauthorization Act (SARA) of 1986 was enacted by Congress to help local communities protect public health, safety, and the environment from chemical hazards. Section 302 defines a list of extremely hazardous substances (EHSs). The presence of EHSs in amounts in excess of a "threshold planning quantity" requires that certain emergency planning activities be conducted.

The initial list in Section 302 of extremely hazardous substances is based on the list of substances published in November 1985 by the U.S. EPA in Appendix A of the "Chemical Emergency Preparedness Program Interim Guidance." Substances are listed based on concerns about acute toxicity, reactivity, volatility, dispersability, combustability, or flammability.
