In 1990, the US Environmental Protection Agency (EPA) revised procedures for evaluating uncontrolled releases of hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA). These revised procedures include substantial changes to the Hazard Ranking System (HRS), the scoring system EPA uses to assess a site`s relative threat to public health and the environment. This information brief provides an overview of the HRS as it applies to DOE facilities and the relationship of the HRS to other site activities under CERCLA and the Resource Conservation and Recovery Act (RCRA).
