What does CERFA clarify regarding remedial action?

The correct answer highlights that less contaminated parts of Superfund sites can indeed be sold. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, allows for the management of contaminated sites. Under this legislation, it is possible to delineate areas within a contaminated site that are less impacted by hazardous substances. These areas can be sold or reused, promoting redevelopment and economic revitalization while still managing the overall site’s contamination issues.

This provision is particularly significant because it offers a pathway for communities to move forward with development opportunities, rather than being entirely hampered by the presence of contamination. It supports the idea that not all parts of a site are equally polluted and that careful assessment can lead to productive reuse of contaminated properties.

The other options do not accurately reflect the intent and provisions of the CERCLA framework. The law does not mandate full immediate cleanup for all sites; rather, it focuses on managing risks based on contamination levels. It also does not state that remedial actions are unnecessary for undeveloped sites or that public health assessments are unnecessary for remediation, as these assessments are fundamental to understanding the risks posed by contaminants and determining the appropriate remedial actions.
