The National Priorities List (NPL) identifies hazardous sites under which act?

The National Priorities List (NPL) identifies hazardous sites under the Superfund Act, formally known as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This legislation was enacted in response to growing concerns about hazardous waste and its impact on human health and the environment.

The Superfund Act provides the necessary framework for identifying and cleaning up some of the most contaminated sites in the United States. The NPL is a list of those sites that have been prioritized for cleanup based on their risk to human health and the environment. This process is vital because it ensures that limited federal resources are allocated to the most pressing cases of contamination.

The other acts mentioned, while important in their own right, serve different purposes. The Clean Water Act focuses primarily on regulating discharges of pollutants into the waters of the United States, while the Resource Conservation and Recovery Act governs the disposal and management of solid and hazardous waste. The Toxic Substances Control Act addresses the regulation of industrial chemicals but does not specifically identify or prioritize hazardous waste sites.
