1. National Priorities List (NPL): This list identifies sites that pose the greatest risk to health and the environment, prioritizing them for long-term cleanup efforts. 2. Remedial Investigation and Feasibility Study (RI/FS): These studies determine the nature and extent of contamination and evaluate potential cleanup options. 3. Record of Decision (ROD): A document that outlines the chosen cleanup method for a site. 4. Potentially Responsible Parties (PRPs): CERCLA enforces the "polluter pays" principle, holding parties responsible for contamination accountable for the costs of cleanup.
