What is one of the primary responsibilities of the EPA under the SARA amendments?

The primary responsibility of the EPA under the Superfund Amendments and Reauthorization Act (SARA) is to revise and update the Hazard Ranking System (HRS). The HRS is a key tool used by the EPA to evaluate and prioritize sites for cleanup under the Superfund program. This revision process helps ensure that the HRS remains effective in assessing the potential risks associated with hazardous waste sites, allowing the agency to focus resources on the most critical areas that pose the highest threat to human health and the environment. By updating this system, the EPA can adapt to new scientific data and emerging environmental issues, thereby enhancing its ability to manage and mitigate the risks associated with hazardous substances.
